Rozdělovací koeficienty příměsí v hořčíku | Results of a systematic study of available magnesium-admixture binary systems are presented in this work. By means of second-degree polynomials solidus and liquidus curves in the region of the melting point of pure magnesium are expressed for 43 systems. Values of equilibrium distribution coefficients of admixtures in magnesium are determined. These values represent the main material parameters of the zone melting and directional solidification and the results are compared with experiments. The periodic correlation dependence of distribution coefficients of admixtures in magnesium on the proton number of admixtures is drawn up. This dependence enables to predict the behaviour of other admixtures during the crystallization of magnesium. |
Developing care in the community: GPs and the HIV epidemic | Abstract Services for HIV infection and AIDS in Parkside DHA have been largely hospital based with little active involvement of local GPs. In response to the wishes of those with HIV/AIDS and predicted increases in the number of patients the DHA is now developing an AIDS strategy which identifies the development of primary and community care as a major objective. A postal survey of all 263 GPs within the DHA was undertaken in order to ascertain their views about the role of primary care in the management of HIV infection/'AIDS. Replies were received from 75% (196). The responses to the survey indicated both the potential of general practice and willingness of GPs to be involved in the care of this client group. However, two key issues in developing this strategy were identified. These were information exchange and confidentiality. It is suggested that both hospitals and general practice must develop rigorous confidentiality policies to overcome these difficulties. |

Products of hermitian matrices and symmetries | It is the main purpose of this note to prove that every complex matrix with real determinant is the product of four hermitian matrices; Theorem 2 is an actually stronger result. Every real square matrix is the product of two real hermitian matrices [1]; this is a special case of our Theorem 1 which is of interest in itself, if it is indeed new. Theorem 3 was motivated by a theorem of Halmos and Kakutani [3 ] who proved that every unitary operator on an infinitedimensional Hilbert space is the product of four symmetries (i.e., operators that are hermitian and unitary). We also show that the number of factors in these results cannot be reduced in general. |
Prognostic value of a prepartum and intrapartum risk-scoring method. | A simple prepartum and intrapartum scoring technic for the identification of high-risk patients was applied to 1,224 patients managed at the Charleston Area Medical Center, Memorial Division. The patients were classified as being at low, moderate, or high risk, according to the total risk score. Perinatal mortality worsened as the risk category increased. Seventy percent of all perinatal deaths occurred in 25% of patients who were identified as moderate- and high-risk patients. The simple one-page scoring form that we used seems to be practical and effective in identifying patients at risk. Such information can be very useful in providing appropriate levels of obstetric care. |
A Subtour Elimination Algorithm for the Bottleneck Traveling Salesman Problem. | Abstract : In this paper we propose a LIFO implicit enumeration algorithm for the bottleneck traveling salesman problem which uses the bottleneck assignment problem as a relaxation. We also present computational experience on a UNIVAC 1108 with symmetric and asymmetric problems, ranging in size from 30 to 2000 nodes. Our results indicate that for asymmetric problems the time requirement of the proposed algorithm grows slower than the square of the problem size -- i.e. the algorithm is empirically good (in the sense of Edmonds).

Optimal design of single phase permanent magnet brushless DC motor using particle swarm optimisation | Purpose – The purpose of this paper is to perform an optimal design of single phase permanent magnet brushless DC motor (SPBLDCM) using efficiency of the motor as objective function. In the design procedure performed on SPBLDCM, particle swarm optimisation (PSO) as an optimisation tool is used. Design/methodology/approach – The created computer programme for optimal design of electrical machines is based on the PSO. According to the design characteristics of SPBLDCM, some of the motor parameters are chosen to be constant and others variable. A comparative analysis of both motor models based on the value of the objective function, as well as the values of the optimisation parameters, is performed. Findings – From the comparative data analysis of both motor models, it can be concluded that the main objective of the optimisation is realised, and it is achieved by an improvement of the efficiency of the motor. Originality/value – An optimisation technique based on PSO has been developed and applied to the des... |

Sulfur species at chalcopyrite (CuFeS2) fracture surfaces | Pristine fractured surfaces of chalcopyrite (CuFeS2) have been studied using Synchrotron Radiation X-ray Photoelectron Spectroscopy and conventional X-ray Photoelectron Spectroscopy. These high-resolution spectra reveal for the first time three distinct contributions to the S 2 p spectrum. The main symmetric peak is located at 161.33 eV and is likely derived from fully coordinated bulk S atoms. A core-level shifted peak was observed at 160.84 eV and is attributed to surface monomeric species (S2−). A second broad contribution at 161.88 eV likely represents surface polymeric species (![Formula][1] ). The data suggest that surface polymers form where S-terminated surfaces such as the (111) plane are exposed during fracture. ::: ::: [1]: /embed/tex-math-1.gif |
GEOTECHNICAL PROPERTIES OF SALT MARSH AND TIDAL FLAT SUBSTRATES AT TILLINGHAM, ESSEX, UK. | Salt marshes and, to a lesser extent, tidal flats, attenuate incoming hydrodynamic energy, thus reducing flood and erosion risk in the coastal hinterland. However, marshes are declining both globally and regionally (the Northwest European region). Salt marsh resistance to incoming hydrodynamic forcing depends on marsh biological, geochemical and geotechnical properties. However, there currently exists no systematic study of marsh geotechnical properties and how these may impact both marsh edge and marsh surface erosion processes (e.g. surface removal, cliff undercutting, gravitational slumping). This has led to poor parameterization of marsh evolution models. Here, we present a systematic study of salt marsh and tidal flat geotechnical properties (shear strength, bulk density, compressibility, plasticity and particle size) at Tillingham, Essex, UK. |
Thin films of WO3 for practical electrochromic windows | Abstract It is shown that practical spectrally-selective transmittance modulation can be achieved with thin (50–100 nm) WO3 films, and therefore such films should be useful for fabricating electrochromic windows. The transmittance and reflectance modulation results are compared with theoretical predictions. The results indicate an excess intraband absorbance, which is attributed to free electron scattering arising from extended defects. |
Vacuum apparatus, vacuum processing system and pressure control method of vacuum chamber | The present invention relates to a vacuum device, a vacuum treating system and a pressure control method of vacuum chamber. The rapid opening of gate valve can be prevented at the state that the supply of air for the action of gate valve in the vacuum chamber is insufficient. In a pressure control mechanism (201), when the air supplying into a cylinder (123) is stopped, the port of mechanical valve (121) is switched, and a pneumatic valve (113) is opened. The external gas gradually flows into a conveying chamber (3) in the vacuum state through a vacuum leakage port (109), a gas introduction tube (111) and a communicating hole (107). The pressure control of conveying chamber (3) is executed with a one-way valve (103) and a buffer vessel (105) at a state that the state of gas for the actionof cylinder (47) is ensured. Therefore, the rapid opening of gate valve (7b) can be prevented. |

[Case of pancreatic ascites successfully treated with endoscopic pancreatic drainage]. | We report a 47-year-old man with abdominal distension without other distinct signs. Massive ascites with any singular lesions was revealed on computed tomography, and the ascites was high-amylase and high-protein. on these findings, pancreatic ascites was suspected and he was first treated with conservative therapy, but it failed. Computed tomography one month from the start of therapy demonstrated a pancreatic cyst, and endoscopic retrograde pancreatography revealed transudation of contrast medium from the cyst. A pancreatic duct stent was placed, and the ascites was smoothly eliminated. Endoscopic pancreatic stenting is considerable treatment for pancreatic ascites. |
CTAB-Influenced Electrochemical Dissolution of Silver Dendrites | Dendrite formation on the electrodes of a rechargeable battery during the charge–discharge cycle limits its capacity and application due to short-circuits and potential ignition. However, understanding of the underlying dendrite growth and dissolution mechanisms is limited. Here, the electrochemical growth and dissolution of silver dendrites on platinum electrodes immersed in an aqueous silver nitrate (AgNO3) electrolyte solution was investigated using in situ liquid-cell transmission electron microscopy (TEM). The dissolution of Ag dendrites in an AgNO3 solution with added cetyltrimethylammonium bromide (CTAB) surfactant was compared to the dissolution of Ag dendrites in a pure aqueous AgNO3 solution. Significantly, when CTAB was added, dendrite dissolution proceeded in a step-by-step manner, resulting in nanoparticle formation and transient microgrowth stages due to Ostwald ripening. This resulted in complete dissolution of dendrites and “cleaning” of the cell of any silver metal. This is critical for p... |
Concurrent small bowel adenocarcinoma and carcinoid tumor in Crohn's disease--case report and literature review. | Adenocarcinomas of the large and small bowel, as well as intestinal carcinoid tumors have been reported at increased rates in Crohn's disease. We herein report a rare case of concurrent adenocarcinoma and carcinoid tumor of the small bowel presenting as intestinal obstruction and found incidentally at laparotomy in a 55 year old male with longstanding ileal Crohn's disease. We performed a Medline Pubmed search for cases of synchronous or composite adenocarcinoma and carcinoid tumor in the setting of Crohn's disease and identified four similar cases. Concurrent adenocarcinoma and carcinoid tumor occurred both in newly diagnosed and longstanding Crohn's disease, most commonly involved the terminal ileum and presented with symptoms mimicking Crohn's disease. Diagnosis was made incidentally at laparotomy in all cases. Lymph node involvement was variable. Clinicians should be aware of this rare entity for expeditious surgical intervention. |
Dynamic changes of platelet endothelial cell adhesion molecule-1 (PECAM-1/CD31) on pulmonary injury induced by ischemia-reperfusion in rats. | OBJECTIVE ::: To evaluate the dynamic changes of PECAM-1/CD31 on pulmonary injury induced by ischemia-reperfusion (IR) in rats. ::: ::: ::: METHODS ::: An isolated lung ischemia in rats was performed for 60 min, followed separately by 0, 2, 4, 6 or 8 h for reperfusion. At the end of reperfusion, the expression of PECAM-1/CD31 was detected by using flow cytometry (FCM). Simultaneously, we examined the ultrastructure changes of cells by transmission electron microscope. ::: ::: ::: RESULTS ::: The expressions of PECAM-1/CD31 in neutrophils and lymphocytes of the blood were increased after IR; the peak was at 2 h after IR, then the expressions were gradually decreased to control level at 6 and 8 h after IR. Ultrastructural morphological changes including proliferation of alveolar type II and apoptotic bodies were seen after IR, the most prominently at 2 h after IR. ::: ::: ::: CONCLUSION ::: PECAM-1/CD31 is involved in the pulmonary injury induced by IR. |
Transfusion-Associated Hepatitis and AIDS | Recent concerns about disease transmission through blood transfusion have prompted frequent questions to physicians about the safety of transfusion. Patients who may need transfusions are anxious to know, often in considerable detail, about their chances of contracting the acquired immunodeficiency syndrome (AIDS) or hepatitis as a result. Patients who have received transfusions ask about their chances of having been infected. Unfortunately, there are few data that allow an easy or accurate answer to either question. The truth is that we do not know the risk of acquiring hepatitis or AIDS as a result of transfusion; the available data permit estimates . . . |

Discipline Domain of Science of Historical Documents | The nature of discipline and object of study of historical documents is still a controversial issue in the academic circle.Based on the literature review,especially that about the nature of discipline and object of study,it is suggested that the study of historical documents should be separated from the general study of documents,namely philology.The interdisciplinary methodology is employed in this research. |
Simple and Efficient Fabrication of Mayenite Electrides from a Solution-Derived Precursor | Mayenite (12CaO·7Al2O3, C12A7) electride with an anti-zeolite nanoporous structure has attracted intense attention due to its versatile promising application potentials. However, the synthesis difficulty because of extremely harsh conditions (e.g., reduction in sealed calcium or titanium vapor) significantly obstructs its realistic applications. In this work, we employed a simple, efficient, and cost-effective route for synthesizing mayenite electrides (C12A7:e–) in both powder and dense ceramic. C12A7:e– powders with efficient electron doping (3.5 × 1020 cm–3) were obtained via simple graphite reduction of a novel mixture precursor of CaAl2O4 (CA) and Ca3Al2O6 (C3A) derived from a modified Pechini method. The structural evolution during the electride formation was investigated, and it was found that reduction below 1300 °C induced the formation of Ca5Al6O14 (C5A3), while reduction above 1400 °C helped retain the mayenite structure. Fully dense C12A7:e– ceramics were also fabricated via graphite reduction... |
Comparison between four piezoelectric energy harvesting circuits | This paper investigates and compares the efficiencies of four different interfaces for vibration-based energy harvesting systems. Among those four circuits, two circuits adopt the synchronous switching technique, in which the circuit is switched synchronously with the vibration. In this study, a simple source-less trigger circuit used to control the synchronized switch is proposed and two interface circuits of energy harvesting systems are designed based on the trigger circuit. To validate the effectiveness of the proposed circuits, an experimental system was established and the power harvested by those circuits from a vibration beam was measured. Experimental results show that the two new circuits can increase the harvested power by factors 2.6 and 7, respectively, without consuming extra power in the circuits. |
Grants Vs Loans! What works best for young entrepreneurs? | Access to formal financial services remains limited in Uganda. Only 4 percent of the youth have access to formal credit institutions. As a result, youth are increasingly accessing microcredit to finance their business enterprises. However, several studies reviewed reveal that in-kind grants perform better than cash grants. In addition, impacts differ across gender with male youths registering more notable successes on business turnover than their female counterparts. Strict eligibility criteria, approval of business plans, family pressure, motivation, initial credit constraints and few initial assets were some of the contributing factors in driving gender differences of financial impacts. |
Null Biminimal General Helices in the Lorentzian Heisenberg Group | In this paper, we study null biminimal curves in the Lorentzian Heisenberg group Heis 3 .

The anthropology of nepotism: Social distance and reciprocity in organizations in developing countries | Nepotism is widespread in organizations in developing countries but has so far received scant attention in cross-cultural management research. The paper seeks to contribute to the underdeveloped research topic suggesting an anthropological explanation of nepotism. It is argued that nepotism reflects the presence of tribal and peasant social morals in organizations where they replace norms and principles typical of industrial society. Examples from African and Latin American organizations show how nepotism works, and drawing on quantitative data it is suggested that nepotism is relatively common in countries at the earlier stages of industrial development. Four managerial approaches to nepotism are outlined: managers can accept nepotistic ambiguity; they can attempt to strengthen the modern organization; they can use the tribal and peasant norms underlying nepotism as the basic principle of the organization; or they can codify the pre-industrial norms and make them part of the formal organization. |
Final-state interactions and neutron-neutron scattering parameters | A method is presented to extend the calculations of McVoy and Bander to determine the low-energy neutron-neutron scattering parameters from the spectrum of the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}+d\ensuremath{\rightarrow}2n+\ensuremath{\gamma}$. The transition amplitude for the capture reaction is derived in the impulse approximation and is related to 12 rotationally invariant amplitudes. The final-state interactions between the two neutrons are treated by means of dispersion relations and a closed-form exact solution is obtained in the effective range approximation and for different Bargmann parametrizations of the $^{1}S_{0}$ neutron-neutron phase shift. A theoretical uncertainty of less than 0.3 fm is expected in the scattering length. |

Excellence or quality? Impact of the current competition regime on science and scientific publishing in Latin America and its implications for development | The current competition regime that characterizes international science is often presented as a quest for excellence. It diversely affects research in Latin America and research in the Organization for Economic Co-operation and Development (OECD) countries. This article asks how this competition regime may orient the direction of research in Latin America, and to whose advantage. It is argued that, by relating excellence to quality differently, a research policy that seeks to improve the level of science in Latin America while preserving the possibility of solving problems relevant to the region can be designed. Competition, it is also argued, certainly has its place in science, but not as a general management tool, especially if the goal is to improve overall quality of science in Latin America. Scientific competition is largely managed through journals and their reputation. Therefore, designing a science policy for Latin America (and for any ‘peripheral’ region of the world) requires paying special atte... |

Dynamic taxation schemes to manage irrigation-induced salinity | This paper uses a dynamic model to explore the issue of irrigation-induced salinity, which puts irrigation at risk in most irrigated areas throughout the world. We address the design of instruments that an irrigation district board could implement to induce irrigators to take sustainable irrigation decisions. In our approach, the irrigators located above an aquifer participate in the accumulation of groundwater, a stock pollution. We analyse input-based instruments to induce the agents to follow the optimal stock path. |
Mood Analysis Recognized on a Movie Script of Toy Story 3 | Key words : mood analysis, functional grammar, movie script This study examines mood analysis in a movie script of Toy Story 3 written by John Lasseter. The researcher has an interest to use conversation in Toy Story 3 movie written by John Lasseter because there are so many clauses that may give a high varied of sentence types and they may give a lot of knowledge related to considerable study. The teory proposed by Halliday (2004) was used as the framework to analyze the mood types and tenor of the discourse built in the movie script and the result of which identified the mood types in the conversation are 28,12% unmarked and 39,19% marked declarative clauses as the majority, it means that the commodity exchange in the movie script is mostly giving information. And then 21,4% wh- and 5,29% polar interrogative clauses as the second majority which consist of 89 wh-clause and 22 polar clause. For the first minority, identified 16 imperative clauses (3,84%) and the second minority is 2,17% exclamative clauses. |
“An Invitation to All Persons:” The Dublin Society and Public Reason in Eighteenth-Century Ireland | The paper explores the activities of the Dublin Society as a form of public reason. Founded in 1731 when the Irish legislature and all trade policy was under the oversight of the British parliament, the Dublin Society undertook two roles usually under the purview of the government: economic improvement and public reason. Rawls’ definitions of public reason, with some qualifications are used. Given the nature of Irish governance, the Society transmutes the idea of public reason into the economic realm. Through its various projects, experiments, contests, schools, and publications, which all had public input, the Society develops a process whereby factual conclusions and social consensus can be made on the Irish economy. Although it did not fully escape the prejudices of its time, the Society provides a larger space than Irish political institutions for members of the public to engage in public reason as economic citizens rather than political or religious ones. |
Neurons of the peripheral nervous system express thymidine phosphorylase | Platelet-derived endothelial cell growth factor (PD-ECGF) is an angiogenic factor which recently has been shown to be identical to thymidine phosphorylase. We describe here, high levels of expression of PD-ECGF/thymidine phosphorylase in neurons of the peripheral nervous system (PNS) but very little in the central nervous system (CNS). Monoclonal and polyclonal antibodies were used for the staining of sections of dorsal root ganglia, sympathetic cervical ganglia and the enteric plexus as well as the brain and spinal cord. In addition, in situ hybridisation confirmed the results of immunohistochemistry. The possible role of thymidine phosphorylase in the PNS is discussed. |

Information analysis techniques for the competitive intelligence process | In this article, the authors discuss useful techniques for information analysis in the CI process. Nowadays, managers usually suffer of a flood of information that takes too much time to select and analyze for decision-making. Managers also are faced with a negotiation or “bargain” process, which requires some kind of mathematical support for ranking alternative actions. The problems of the information flood can be solved through data-mining techniques that allow for the discovery of hidden knowledge in the pieces of available information available. Moreover, a mathematically based decision-making support theory provides “bargaining” support. The authors experience with such techniques is presented. © 2001 John Wiley & Sons, Inc. |
Noncustodial Fathers' Involvement With Their Children: A Right Or a Privilege? | This study explores the key determinants of noncustodial fathers' involvement with their children. The stereotype that fathers have little interest in parenting their children is contradicted. The findings reveal that fathers are committed to parenting; however, actions on the part of the mothers and what the participants perceive to be bias on the part of the courts prevent fathers from having the relationship with their children they desire. Even fathers who have been committed early in the relationship to their children, pay child support, and give no justification for being denied parental rights do not necessarily get to spend time with their children. Parenting plans should be negotiated at the same time as child support orders and revisited periodically. |
TRIPS: ADEQUATE PROTECTION, INADEQUATE TRADE, ADEQUATE COMPETITION POLICY | This article analyzes the relationship between trade and competition pol- icy with respect to intellectual property, focusing particularly on the inclusion into the Uruguay Round of the Trade Related Aspects of Intellectual Property ("TRIPS"). The article sets forth the traditional framework of protection as established by the Paris Convention for the Protection of Industrial Property in 1883. The TRIPS agreement provides new rules and principles to manage emerging problems in the field of industrial property. The main focus of this article is to analyze the effect that TRIPS will have on harmonizing (but not unifying) the system of intellectual property protection. |
Clinical significance of contagious disease indexes detection in patients preparing for blood transfusion | OBJECTIVE To investigate the prevalence of hepatitis B surface antigen(HBsAg),hepatitis C antibody(anti-HCV),human immunodeficiency virus antibody(anti-HIV)and anti-Treponema pallidum antibody(antiTP)in patients preparing for treatment of blood transfusion.so as to provide proofs to reduce the risk of blood transfusion and enhance the doctors and nurses′consciousness of self protection.METHODS From 2010to 2012.4152patients in the hospital were recruited.The detection of HbsAg,anti-HCV and anti-HIV was performed by ELISA method.RESULTS Among the 4152patients,the positive rates of HbsAg,Anti-HCV and anti-TP were15.07%,1.37% and 3.66%,respectively,while anti-HIV was only detected in one patient 0.02%.CONCLUSION Although the prevalence of the markers for transmission diseases is still low,the importance of detecting these markers should be concerned. |

Resistance and accommodation: factors for the (non-) adoption of machine translation among professional translators | ABSTRACTDespite considerable advances in machine translation (MT), adoption by professional translators still meets with resistance. Research on the human factors associated with MT (non-)adoption is required to understand this state of affairs. We investigate whether two specific groups of professional translators use MT, what reasons they advance for its use/non-use and what factors might explain the reasons given. Participants advanced an equally diverse set of reasons for using MT as for not using it, and this was strongly linked to text type, language pair, quality and trust. Using an agency theory lens, we found evidence of Pickering’s dialectics of resistance and accommodation in the focus group data. We also found that one group of translators is more open to the use of MT, and suggest that the socio-technical context of deployment might explain this finding. |
[Modifications of respiratory function during pregnancy]. | During pregnancy, changes in the thoracic configuration subsequent to progressive increase in the abdominal volume have a moderate effect on respiratory function. The cephalic displacement of the diaphragm reduces the expiratory reserve volume and the residual volume. The main consequence is an increase in the closing volume of the airways due to the fact that the lower residual functional capacity occurs during the tidal volume. The increase in the closing volume decreases the ventilation of the adjacent alveolar areas which could explain an increased heterogenicity of the ventilation-perfusion ratios. Increased tidal volume is almost always observed during pregnancy and is the cause of hyperventilation and a major increase in alveolar ventilation which can reach 70% of the post partum value. This hyperventilation is probably due to increased chemosensitivity of the CO2 respiratory centers induced by the hyperprogesteronism observed during pregnancy. |
Bone Mineral Density Changes Among Young, Healthy African Women Receiving Oral Tenofovir for HIV Preexposure Prophylaxis | Background: ::: Limited data exist on effect of tenofovir disoproxil fumarate (TDF) when used for preexposure prophylaxis (PrEP) on bone mineral density (BMD) in HIV-negative women.

[Two site-specific endonucleases from the thermophilic strain Bacillus species LU11]. | Upon screening of natural strains of thermophilic bacteria, a strain has been found which contains two restriction endonucleases. One of those, BspLU11II, is an isoschizomer of XbaI, while the other one, BspLU11I, recognizes the new palindromic sequence 5'-A decreases CATGT-3' and cleaves it as indicated by the arrow. Functionally pure enzymes were obtained by stepwise chromatography with blueagarose, hydroxyapatite and heparin-Sepharose. The restriction endonuclease BspLU11I produces sticky ends identical to those produced by the restriction endonuclease NcoI; hence a combination of BspLU11I and NcoI can be used for enzymatic selection of recombinant DNA. The recognition sequence of BspLU11I contains the ATG codon and can be used to construct expression vectors for chemically synthesized genes. |
Checking integrity of data and recovery in the cloud environment | Cloud computing provides many services to access them dynamically over the internet as per the user's demand. The data is growing in tremendous amount and it should be managed correctly where storage service proves efficient. The Data stored online can be hacked by the third party so to secure this data verifying integrity is essential. Because of the human error or natural disaster, the data may get deleted from the cloud servers. Therefore, there is a requirement of improving the existing algorithm to recover data efficiently. Many algorithms are proposed, but they lack in efficiency, computational cost, and reliability. The proposed system in this paper is having the feature of verifying data integrity using Identity Based Remote Data Integrity Checking and recovery using the XOR operation. When the data is unavailable to the user, the proposed system provides flexibility for the user to regain data from the remote server. |

A high-throughput, low-cost method for the preparation of "sequencing-ready" phage DNA template. | We have developed a simple and efficient protocol for the isolation of good-quality recombinant phage DNA useful for all downstream processing, including automated sequencing. The overnight-grown phage particles were effectively precipitated (without any contaminating Escherichia coli DNA and other culture media components) by adjusting the pH of the culture medium to 5.2 with sodium acetate, followed by addition of ethanol to 25%. The phage DNA was selectively precipitated with ethanol in the presence of guanidinium thiocyanate under alkaline pH, resulting in uniform quality and quantity of phage DNA. The quality of the phage DNA preparation was demonstrated by DNA sequencing that provided an average read length of >700 bases (PHRED20 quality). This protocol for plating, picking, growing, and subsequent DNA purification of individual phage clones can be completely automated using any standard robotic platform. This protocol does not require any commercial kits and can be completed within 2 h. |

Application of the Meikirch Model to independent medical evaluations for Social Security eligibility determinations in Switzerland and potential for use by physicians in many other situations | The Meikirch Model of Bircher and Kuruvilla provides a new and very interesting definition of health and disease, based on a biopsychosocial framework and the idea of an interaction of an individual with social and environmental determinants of health. It is a modern systems approach, not only for acute, but particularly for chronic diseases. For this reason, I have adopted this analytic approach for conducting independent medical evaluations in the Swiss system of Social Security. |
Securing the Automobile: a Comprehensive Approach | Previous research has demonstrated the software and network vulnerabilities that exist in modern automobiles.

Spherical nonspreadingness of resolvents of convex functions in geodesic spaces | In this paper, we propose the concepts of a spherically nonspreading mapping and a firmly spherically nonspreading mapping in a complete geodesic space with curvature bounded above by one and we prove that the resolvent of a proper lower semicontinuous convex function in that space is both well defined and firmly spherically nonspreading. We further discuss the existence and approximation of fixed points of such mappings and apply our results to convex optimization in geodesic spaces. |
IDENTIFICATION OF FLAVOUR COMPONENTS IN INSTANT RICE PROCESSED BY STEAMING AND BOILING AT FIRE | The flavour components produced in processing instant rice by both steaming and boiling at fire were extracted by synchronous distillation and extract(SDE), and 44 and 69 flavour components produced with two processing methods were respectively identified by mass spectroscopy. A comparison as to the relative quantity of flavour components was made. The result showed that the instant rice by boiling at fire had much better flavour than that by steaming. |
Detection of Chondromalacia Patellae by Analysis of Intrinsic Mode Functions in Knee-Joint Vibration Signals | This paper presents the knee-joint vibration signal processing and pathological localization procedures using the empirical mode decomposition for patients with chondrom alacia patellae.The artifacts of baseline wander and random noise were identified in the decomposed monotonic trend and intrinsic mode functions (IMF) using the modeling method of probability density function and the confidence limit criterion.Then, the fluctuation parts in the signal were detected by the signal method turning for count. The results demonstrated that the quality of reconstructed signal can be greatly improved, with the removal of the baseline wander(adaptive trend) and the Gaussian distributed random noise. By detecting the turn signals in the artifact-free signal, the pathological segments related to chondrom alacia patellae can be effectively localized with the beginning and ending points of the span of turn signals. |
Research and Development of Digital Design Manufacturing System about shoe last | Shoe last is the basis of shoes,of which the manufacturing process is one of the key processes for shoe-making.It is of great significance to enhance the design and manufacture level of shoe last using digital technology.In the system,a reverse engineering device for measuring and reconstruction of shoe last(foot-model)3D solid model is developed applying stereo vision technique,then the solid model database of shoe last is set up,therefore,the digital management for shoe last(foot-model)3D solid model can be carried out.On this basis,some local modification is made using CAD technology,and the re-design of shoe last is realized.Finally,a software is developed,by which the tool path and NC code of shoe last processing can be generated from the shoe last CAD solid model directly.Thus the integration of digital design and manufacture for shoe last is achieved. |

A 3D Ground Object Model Base on Spatial Cognition | With the development of 3D-GIS and Web 3D-GIS,the conflict between huge data in 3D GIS and the limited computer resource become more and more obviously,especially for the huge data volume of 3D ground object model.Based on Spatial Cognition Theory,a object-oriented design method is presented here,which can reduces the data volume of 3D ground object model and benefit for model multi-scale display in LOD.This paper presets the theoretical basis of model design.An experiment is carried out with 3Dmodel tool of 3DMax,which proves the method has good effect. |
HR practices and turnover intention: the mediating roles of organizational commitment and organizational engagement in a selected region in Malaysia | This study examined the mediating effects of organizational commitment (OC) and organizational engagement (OE) on the relationship between human resource (HR) practices (career management, performance appraisal, compensation, person–job fit and job control) and turnover intention. A total of 457 employees working in various sectors in a selected region in Malaysia participated in this study. It was found that all the variables used to measure HR practices have significant effects on OC and OE. However, multiple regression analyses indicated that career management and job control did not have any significant influence on turnover intention. OC and OE were discovered to give partial mediating effects on the relationship between HR practices and turnover intention. |

Target feature extraction of infrared image of landmine field based on wavelet decomposition | To extract target feature of infrared image with low SNR, a new scheme based on combination of wavelet decomposition and energy feature is proposed in this paper. According to the energy distribution defference between target and background in wavelet field, the target feature is extracted by calculating the energy feature values of every subchannels obtained from multiscale decomposing. The experimental results demonstrate the vaility of the presented scheme . |
Energy threshold effects in the collisionless dissociation of polyatomic molecules by ir laser radiation | The threshold for collisionless dissociation of SF6, SiF4, and CF2Cl2 by focused CO2 laser radiation has been measured. This threshold is a laser pulse energy effect and, within experimental error, is found to be the same for all three gases. Provided collisions cannot occur during the laser pulse, the degree of dissociation produced depends only on the energy in the pulse, which is consistent with simple adiabatic vibrational heating of the molecules by the laser. |
Muscle ammonia stores are not determined by pH gradients | The theory of non-ionic diffusion predicts that ammonia will distribute between intracellular and extracellular tissue compartments according to transmembrane pH gradients. The distribution of ammonia and14C-DMO were compared in white muscle and plasma of rainbow trout (Salmo gairdneri) at rest, and following exhaustive exercise. Under both experimental conditions, intracellular ammonia levels far exceeded those predicted by transmembrane pH gradients. Calculated equilibrium potentials for\(NH_4^ + (E_{NH_4^ + } )\)) were very close to published resting values of membrane potential Em in fish white muscle. We conclude that NH 4 + is permeable across cell membranes and that intracellular ammonia stores are not determined by pH gradients. |
The study of a fluorescent biosensor based on polyelectrolyte microcapsules with encapsulated glucose oxidase | A fluorescent biosensor is synthesized and described. The biosensor consists of polyelectrolyte microcapsules with glucose oxidase (GOx) entrapped in the cavities and an oxygen-sensitive fluorescent indicator Ru(dpp) immobilized in shells, where Ru(dpp) is tris(4,7-diphenyl-1,10-phenanthroline)ruthenium(II) dichloride. The theoretical activity of the encapsulated GOx and the effect storage time and medium composition have on the stability of sensor microcapsules are determined from polarographic measurements. No change in the activity of the encapsulated enzyme and or its loss to the storage medium are detected over the test period. The dispersion medium (water or a phosphate buffer) are shown to have no effect on the activity of microcapsules with immobilized GOx. The described optical sensor could be used as an alternative to electrochemical sensors for in vitro determination of glucose in the clinically important range of concentrations (up to 10 mmol/L). |
Comparison of whole-body low-dose computed tomography and conventional radiography in the staging of multiple myeloma | e120 Conclusion: Our data suggests that AKI due to ATN at the time of myeloma diagnosis is more likely to recover compared to MCN with a faster time to response.

Effects of sulfur dioxide on resistance to bacterial infection in mice. | Abstract Continuous exposure to approximately a 10-ppm concentration of sulfur dioxide for periods of up to 3 weeks reduced the resistance of female mice to infection by aerosol inoculation with Klebsiella pneumoniae . The mortality rate rose and survival time shortened in SO 2 -exposed animals compared to controls. Insofar as these results can be extrapolated to humans, the SO 2 concentration used in this work is only found on certain industrial premises. |
Cornish Bagpipes: Fact and Fiction | The Cornish bagpipe Pyba is closely connected to the music revival in Cornwall, UK, which started in the late 1970s. Belonging to one of the six so-called Celtic nations - alongside Ireland, Scotland, Wales, the Isle of Man and Brittany - the Cornish revivalists were eager to promote Cornwall’s music as Celtic rather than English. They saw the bagpipe as a particularly Celtic instrument, which would legitimise their claim for a unique musical Cornish heritage and might promote Cornwall’s Celticity at parades on local feast days and at Interceltic Festivals. |
Localization and identification of three-dimensional sound source with beamforming based acoustic tomography | Beamforming based commercial planar microphone array could only localize and identify the sound source when the distance between source and array is known. This paper presents a beamforming based acoustic tomography (BBAT) method to locate and identify the source in 3D space, say, the BBAT method can not only locate the source in X-Y plane that is parallel to the array, but also the depth Z of the source. In this method, the sound field is reconstructed on the virtual planes at different distances along depth direction (Z direction). The maximum response of sound field on every virtual reconstruction plane is tracked, where the largest value among those maximum responses appears at Z direction is the depth of the source. The location of source at X and Y directions can then be easily identified based on beamforming principle, which is utilized by commercial planar array. The BBAT method is evaluated theoretically by simulation of monopole source, the experimental evaluation is done as well in anechoic cha... |
Heideggerian epistemology and personalized technologies | The paper examines the personalization of information technology from the p.c. onwards to the 3-D printing and mobile technologies in order to show that the current process of technological evolution puts the human personality in the centre of its functionality. This new centre opens the discussion about authenticity and in-authenticity of human Dasein, since the common element of these new technologies is that they employ faciality and personalization in a new condition of ready-to-hand and present-at-hand mode. By applying the Heideggerian modes of being on the process of personalization new forms of digital ethics appear. I suggest that the above take place in the navigation memory of the net, in the creativity of the self through the 3-D printer, and in the localization of the "psyche" in the hard drive disk. The paper defends the possibilities of an ethical, authentic and sheltering personalization, where human beings and information technology responsibly engage. |

Statistical analysis of the Wigner-Ville distribution with applications to wideband detection | A time-frequency statistical description of the Wigner-Ville distribution of random processes that exploits the statistical parameters constituting the Karhunen-Loeve expansion of the original time process is introduced. This provides a method for constructing Wigner-Ville-based detector structures that are of analytical handiness. As an illustration of the utility of this statistical analysis, an algorithm for detection of weak signals of unknown parameters that are obliterated by additive wideband Gaussian noise is proposed. The algorithm utilizes samples from an orthogonal function expansion in the time-frequency domain, the performance measure of which is ascertained. Theoretical evidence of its potential superiority over the radiometer (an energy-detecting device) is presented. Monte-Carlo simulations are then implemented to demonstrate its effectiveness and display probability performance curves. > |
The three Rs and high school writing instruction: bridging in- and out-of-school writing to reach “struggling writers” | We present a novel take on “the three Rs” – in this case recognition, relevance and renegotiation – as an approach to bridging in- and out-of-school writing practices with struggling high school writers. Our study draws on a year-long research project involving a university literacy instructor co-teaching a composition class in an urban, alternative school for former dropouts. We use socio-cultural and socio-historical literacy theories, in particular the New Literacy Studies framework, to argue that educators need to help students recognize Discourse practices as arbitrary or socially and historically constructed rather than immutable. We need to help students see themselves as successful writers in contexts other than school and begin to draw on various writing conventions in order to renegotiate their status as “novice”, “failing” or “incompetent” writers. In making these efforts, we can help “struggling” students become competent, confident and empowered writers. |

Revised Uncertainties in Big Bang Nucleosynthesis | Big Bang Nucleosynthesis (BBN) explores the first few minutes of nuclei formation during the Big Bang. We present updated 2σ for the abundances of the four primary light nuclides — D, 3He, 4He, and 7Li — in BBN. A modified standard BBN code was used in a Monte Carlo analysis of the nucleosynthesis uncertainties as a function of the baryon-to-photon ratio. Reaction rates were updated to those of NACRE, REACLIB, and R-Matrix calculations. The results were then used to derive a new constraint on the effective number of neutrinos. |
Probe of the Josephson vortex lattice in BSCCO-2212 single crystal | Interlayer coupling in Bi2Sr2CaCu2O8+σ (BSCCO-2212) is examined with the out-of-plane resistance,R, in magnetic field,H, up to 15T applied parallel to (ab)-plane of a single crystal withT c >90K. Sharp hysteretic jump in the tail ofR(T, H) curve is observed at 5.5≤H≤11T while the crossover to the monotonousR(T) curve of non-Arrenius type occurs beyond that range of fields. Effect is found to be completely wiped out by the minor tilt of the crystal from the orientationH‖(ab) and could be related with a first-order phase transition in the Josephson vortex system. |
Precautionary Volatility and Asset Prices | Many theories of asset prices assume time-varying uncertainty in order to generate time-varying risk premia. This paper generates time-varying uncertainty endogenously, through precautionary saving dynamics. Precautionary motives prescribe that, in bad times, next period's consumption should be very sensitive to news. This time-varying sensitivity results in time-varying consumption volatility. Production makes this channel visible, and external habit preferences amplify it. An estimated model featuring this channel quantitatively accounts for excess return and dividend predictability regressions. It also matches the first two moments of excess equity returns, the risk-free rate, and the second moments of consumption, output, and investment. |
Rotating topological black holes | A class of metrics solving Einstein's equations with a negative cosmological constant and representing rotating, topological black holes is presented. All such solutions are in the Petrov type-$D$ class, and can be obtained from the most general metric known in this class by acting with suitably chosen discrete groups of isometries. First, by analytical continuation of the Kerr\char21{}de Sitter metric, a solution describing uncharged, rotating black holes whose event horizon is a Riemann surface of arbitrary genus $gg1,$ is obtained. Then a solution representing a rotating, uncharged toroidal black hole is also presented. The higher genus black holes appear to be quite exotic objects; they lack global axial symmetry and have an intricate causal structure. The toroidal black holes appear to be simpler; they have rotational symmetry and the amount of rotation they can have is bounded by some power of the mass. |

Genetic relationships between Bidens forbesii and six species in the Hawaiian and the Marquesas Islands | A crossing program was carried out between the Kauai endemicB. forbesii and six other Polynesian species, five of which are Hawaiian and one Marquesan. All crosses produced vigorous F1 hybrids, portraying a strong genetic relationship betweenB. forbesii and the other species. The results indicate a close systematic relationship among the Polynesian species ofBidens placed by Sherff in sect.Campylotheca and strengthen the argument that this group dispersed from North America to the Hawaiian Islands, then from Hawaii to the Marquesas Islands. |
Rotationally resolved A 3 R -X 3 Rspectrum of HC 7 H | The A 3 R � u –X 3 R � g electronic spectrum of the linear carbon chain radical HC7H has been recorded fully rotationally resolved. Cavity ring-down spectroscopy is used to record the origin band transition in direct absorption through a supersonically expanding planar plasma, discharging a diluted gas mixture of acetylene in helium. Rotational resolution is obtained by operating a commercial pulsed dye laser system in a second grating order configuration, resulting in a narrower bandwidth of about 0.035 cm � 1 . In total, 39 |

The power Tx consists of an inverted L-shaped open stub. The power Rx consists of two inverted L-shaped open stubs based on method of image, and a differential output can be obtained by it. Our power Tx and Rx are explained by the equivalent circuits and are designed through electromagnetic simulation. From the measurement results at multiple positions, it was revealed that the higher RF-dc efficiency was achieved at all positions than the conventional monopole probes. |
Aspect Separation in Web Service Orchestration: A Reflective Approach and its Application to Decentralized Execution | Web service orchestration is becoming widely spread for the creation of composite Web services using standard specifications such as BPEL4WS. The myriad of specifications and aspects that should be considered in orchestrated Web services are resulting in increasing complexity. This complexity leads to software infrastructures difficult to maintain with interwoven code involving different aspects such as security, fault tolerance, distribution, etc. In this paper, we present ZenFlow a reflective BPEL engine that enables to separate the implementation of different aspects among them and from the implementation of the regular orchestration functionality of the BPEL engine. We illustrate its capabilities and performance exercising the reflective interface through a decentralized orchestration use case. |
Delayed hydrological response to Greenland cooling at the onset of the Younger Dryas in western Europe | During the Younger Dryas cold event about 12,800 years ago, environmental change in western Europe seems to occur 170 years after cooling over Greenland. Lake sediment analyses confirm this delay, and suggest European hydrological and vegetation change occurred only after the build-up of sea ice in the North Atlantic pushed the westerly wind system south. |

Finite homogeneous deformations of symmetrically loaded compressible membranes | Abstract.The equilibrium problem of nonlinear, isotropic and hyperelastic square membranes, stretched by a double symmetric system of dead loads, is investigated. Depending on the form of the stored energy function, the problem considered may admit asymmetric solutions in addition to the expected symmetric solutions. For compressible materials, the mathematical condition allowing the computation of these asymmetric solutions is given. Moreover, explicit expressions for evaluating critical loads and bifurcation points are derived. Results and basic relations obtained for general isotropic materials are then specialized for a compressible Mooney–Rivlin material and a broad numerical analysis is performed. The qualitatively more interesting branches of asymmetric equilibrium are shown and the influence of the material parameters is discussed. Finally, using the energy criterion, some stability considerations are made. |

3D Mapping in Tunnel Environments: Maximizing Mission Range | This paper presents an analysis of the power and computational requirements for 3D tunnel mapping using an autonomous ground vehicle and a single Microsoft Kinect sensor. A comparison of existing mapping algorithms, including RGB-D SLAM and KinectFusion, is performed on a representative hallway to demonstrate the accuracy with which tunnels can be mapped. The power requirements for both the vehicle locomotion and onboard computation are assessed, and representative tunnel mapping ranges are computed. Finally, a system is proposed that minimizes power consumption without sacrificing map quality that could operate continuously for 26 hours and collect over x km of map data, which could be processed online for real-time mapping and refined offline for more accurate results. Extension to UAV/UGV teams is also considered. |
Newt Opportunities for Understanding the Dedifferentiation Process | Urodele amphibians, such as the newt Notophthalmus viridescens, have the unique ability to regenerate limbs, spinal cord, eye structures, and many vital organs through a process called epimorphic regeneration. Although the cellular basis of regeneration has been studied in detail, we know relatively little about the molecular controls of the process. This review provides an overview of forelimb regeneration in the newt, addressing what we know about cellular and molecular aspects. Particular focus is placed on the dedifferentiation process, which yields a population of embryonic-like pluripotent cells that will eventually reform the lost structure. This cellular plasticity seems to be the key to regenerative ability. We discuss the dedifferentiation process in newt forelimb regeneration and outline the various studies that have revealed that mammalian cells also have the ability to dedifferentiate if given the appropriate triggers. |
Clinical Guideline-Driven Personalized Self-Management Diary for Paediatric Cancer Survivors | Shared Decision Making (SDM) is the process of patients and clinicians working together to manage medical treatment using the existing knowledge base. This paper presents the YouCan framework, a system for summarizing and presenting the necessary knowledge for SDM related to pediatric cancer follow-up management. Knowledge modelling of a Clinical Practice Guideline produced a customized ontology, which was then passed through a pellet reasoned to produce a customized patient diary that summarizes a patient's oncological history as well as the potential issues they may face in follow-up. |
