A plastic optical fiber and a method for producing the same is disclosed. The plastic optical fiber is formed as a fiber of core-cladding structure. A protective layer or shield layer may be provided on the outer surface of the optical fiber of core-cladding structure for improving thermal resistance of the optical fiber and protecting the optical fiber from air and moisture. The plastic optical fiber uses fluorinated plastic, which contains a rare earth component as a core material, and a cladding material, which does not comprise a rare earth component but essentially consists of a polymer chain, which essentially consists of bonded -ACF2Un- monomers and has a refractive index lower than that of the core material. The optical fiber is produced by a melting-drawing technique.


Developing correct, scalable and efficient concurrent programs is a complex and difficult task, due to the large number of possible concurrent executions that need to be taken into account. Modern multi-core processors with weak memory models and lock-free algorithms make this task even more difficult, as they introduce additional executions that confound the developers' reasoning. Because of these complex interactions, concurrent programs often contain bugs that are difficult to find, reproduce, and fix. Stress testing is known to be very ineffective in detecting rare concurrency bugs as all possible executions of the programs have to be explored explicitly. Consequently, testing by itself is often inadequate for concurrent programs and needs to be complemented by automated analysis tools that enable detection of bugs in a systematic and symbolic way. In the first part of the talk, I provide an overview of Lazy-CSeq, a symbolic method based on Bounded Model Checking (BMC) and Sequentialization. Lazy-CSeq first translates a multi-threaded C program into a nondeterministic sequential C program that preserves reachability for all round-robin schedules with a given bound on the number of rounds. It then re-uses existing high-performance BMC tools as backends for the sequential verification problem. This translation is carefully designed to introduce very small memory overheads and very few sources of nondeterminism, so that it produces tight SAT/SMT formulae, and is thus very effective in practice. In the second part of the talk, I present Swarm-CSeq, which extends Lazy-CSeq with a swarm-based bug-finding method. The key idea is to generate a set of simpler program instances, each capturing a reduced set of the original program's interleavings. These instances can then be verified independently in parallel. Our approach is parametrizable and allows us to fine-tune the nondeterminism and randomness used for the analysis. In our experiments, by using parallel analysis, we show that this approach is able, even with a small number of cores, to find bugs in the hardest known concurrency benchmarks in a matter of minutes, whereas other dynamic and static tools fail to do so in hours.


Working towards the 'good society' is an important aspiration to hold, but equally its subjectivity complicates the realisation for all – each person's view of what 'good' means in relation to society differs. The notion is also open to statutory appropriation and mainstreaming using rhetoric to suggest its centrality to governmental thinking, but the reality reveals policy and practice, which undermines the accomplishment of social justice and thus a good society. This paper seeks to explore this complexity through dissecting the processes of representation of the 'good society' in theory and in practice. The paper will argue that the 'good society' might be termed a doxic construct. Bourdieu used 'doxa' to explain how arbitrariness shapes people's acceptance of their place in the world, the covert process is 'internalised', seemingly objectively, into the 'social structures and mental structures', producing a universal and accepted knowledge of something (Bourdieu, 1977). The possibility of difference is undermined; thus, the varied needs and contexts of people's lived realities are consumed within prevailing normative narratives. Foucault (cited in Simon, 1971: 198) referred to a 'system of limits' and Bourdieu (1977: 164) 'sense of limits', both authors will assist in seeking to uncover how such invisible practices limit and constrain the imagining of possibilities beyond the taken-for-granted. The paper argues that community development can be a catalyst to challenge this invisibility by utilising Freire's (1970) conscientisation, enabling people to recognise structural oppression to challenge the status quo. This paper will draw on examples offered within a northern city to build on Knight's, 2015 research, which posed the question '[w]hat kind of society do we want?', identifying, when asked, a hunger for change. The paper explores whether there is a desire to overturn the predominant individualism of the neoliberal era to reignite the notion of the common good.


This paper treats the global stabilization problem of continuous-time switched affine systems that have rank-deficient convex combinations of their dynamic matrices. For these systems, the already known set of attainable equilibrium points has higher dimensionality than in the full-rank case due to the existence of what we define as singular equilibrium points. Our main goal is to design a state-dependent switching function to ensure global asymptotic stability of a chosen point inside this set with conditions expressed in terms of linear matrix inequalities. For this class of systems, global exponential stability is generally impossible to be guaranteed. Hence, the proposed switching function is shown to ensure global asymptotic and local exponential stability of the desired equilibrium point. The position control and the velocity control with integral action of a dc motor driven by an h-bridge fed via a boost converter are used for validation. This practical application example is composed of eight subsystems, and all possible convex combinations of the dynamic matrices are singular.

This radical new reading suggests that Wittgenstein is best understood as a covert Jewish thinker in times of lethal anti-Semitism. The argument first establishes that there was one Wittgenstein, not an « early and a « later. By looking afresh at the role of the Bible, God, Augustine, Otto Weininger, and science, among other things, in Wittgenstein's thought, Ranjit Chatterjee shows how well Wittgenstein matches with Jewish tradition because he had internalized talmudic and rabbinic modes of thought. An abundance of evidence is brought forward of Wittgenstein's Jewish self-identification from his writings and from remarks noted in conversations by his closest friends. Written in an engaging style, this powerful and unexpected understanding of Wittgenstein includes a chapter on his relation to postmodernism (Levinas and Derrida), a personal epilogue, an appendix on his descent, and a full bibliography.


Balance laws arise from many areas of engineering practice specifically from the fluid mechanics. Many numerical methods for the solution of these balanced laws were developed in recent decades. The numerical methods are based on two views: solving hyperbolic PDE with a nonzero source term (the obvious description of the central and central-upwind schemes; (Kurganov & Levy, 2002; LeVeque, 2004)) or solving the augmented quasilinear nonconservative formulation (Gosse, 2001; Le Floch& Tzavaras, 1999; Pares, 2006). Furthermore, the methods can be interpreted using flux-difference splitting (or flux-vector splitting), or by selecting adaptive intervals and the transformation to the semidiscrete form (for example (Kurganov & Petrova, 2000)). We prefer the augmented quasilinear nonconservative formulation solved by the flux-difference splitting in our text. We try to formulate the methods in the most general form. The range of this text does not give the complete overview of currently used methods.

Background Computerized decision support systems (CDSS) and performance-based incentives (PBIs) can improve health-worker performance. However, there is minimal evidence on the combined effects of these interventions or perceived effects among maternal and child healthcare providers in low-resource settings. We thus aimed to explore the perceptions of maternal and child healthcare providers of combined CDSS-PBI support on performance in twelve primary care facilities in Ghana's Upper East Region. Methods We conducted a qualitative study drawing on semi-structured key informant interviews with 24 nurses and midwives, 12 health facility managers, and 6 district-level staff familiar with the intervention. We analysed data thematically using deductive and inductive coding in NVivo 9 software. Results Interviewees suggested

It is an important scientific research object and valuable engineering project to calculate the local geoid accurately.In this paper,the basic method and process to calculate the local geoid are discussed with an instance in some area.


The Earth has been both a habitable and inhabited planet for around 4 billion years, yet distant observers studying Earth at different epochs in our history would have detected substantially different and probably varying conditions. Understanding Earth's history thus has much to tell us about how to interpret observations of potentially habitable exoplanets. In this talk I will review the history of life on Earth, from the earliest microbial biosphere living under a relatively methane-rich atmosphere to the modern world of animals, plants, and atmospheric oxygen, with a focus on how observable conditions on Earth changed as the planet and its biosphere evolved. I'll discuss the implications of this history for assessing the habitability of-or presence of life on-planets around other stars.


A PC based microreactor control system is developed with Visual C++ 6 0 under Microsoft Windows 95/98 environment. The SCADA(System Configuration and Data Aquariums) system controls the reactor through an A/D D/A card. The A/D D/A card receives instructions through its I/O port. We develop a class to encapsulate all I/O operations in SCADA system. This paper demonstrates the object oriented method used in the development of the system and discusses some technical details.


In this article we study the nonlinear Robin boundary-value problem −Δp(x)u = λf(x, u), in Ω ; |∇u| ∂u ∂ν + β(x)|u|u = 0, on ∂Ω. Using the variational method, under appropriate assumptions on f, we obtain a result on existence and multiplicity of solutions.


The Cadi Nu'man b. Muhammad is the jurist and lawgiver of the Fatimids (1); it is on his Da'd'imu 'I-Islam, vol. II, that this my study is principally based. The first volume was edited and published in Cairo in 1951; the edition of the second volume has been delayed for reasons beyond the control of the editor, but he hopes that it will see the light of day in 1958. Nu'man's major works relating to law are the Idah (lost), Iqlisdr (ready for publication by the Institut Frangais de Damas and edited by Dr. Muhammad Wahid MIrz5, Professor and Head of the Department of Arabic and Islamic Culture, Lucknow University), Mukhlasaru 'I-Athdr; Yanba' (only Part II extant), and Tahdra. He also wrote several historical and polemical works. The relation between these works has not yet been definitely established but it seems tolerably clear (a) that the Idah was the original source, now lost; (b) that the Da'd'im came next, to define and consolidate the law; and (c) that the Mukhtasaru 'I-Athdr, for judges, the Iqtisdr, for students, and the Tahdra and the Yanbi' were later productions by other hands. A detailed discussion of this problem would be of great interest, but it is proposed to postpone it to a more convenient occasion. The Book of Inheritance Kitbtu 'l-Fard'id is to be found in


Fournier's gangrene is a rare type of necrotizing fasciitis specific to the superficial fascia and subcutaneous tissues of the external genitalia, perineum, perirectal, and ischiorectal regions. It is usually diagnosed clinically, and imaging is used to support the diagnosis, assess the extent of the necrosis, and aid in surgical planning. Computed tomography (CT) is the primary imaging modality to diagnose Fournier's gangrene, usually after symptoms are severe. Sonography may be used to diagnose early stages of this disease and to differentiate it from intrascrotal pathology or benign cellulitis. A case of Fournier's gangrene is presented that discusses sonographic findings of Fournier's gangrene and the disease process.


Wind farm grid codes require wind generators to ride through voltage sags, which means that normal power production should be re-initiated once the nominal grid voltage has been recovered. Doubly Fed Induction Generator (DFIG) based wind farm is gaining popularity these days because of its inherent advantages like variable speed operation and independent controllability of active and reactive power over conventional Induction Generator (IG). This paper proposes a new control strategy using DFIGs for stabilizing a wind farm composed of DFIGs and IGs. Simulation analysis by using PSCAD/EMTDC shows that the DFIGs can effectively stabilize the IGs and hence the entire wind farm through the proposed control scheme by providing sufficient reactive power to the system.

A theoretical method for predicting the octane number of pure hydrocarbon liquids is presented. The method is based on a structural group contribution approach and requires no experimental procedure or knowledge of the physical or chemical properties only the chemical structure of the molecule. The proposed model is simple and can predict the research and motor octane numbers of more than 200 pure hydrocarbon liquids with an average deviation of 4 and 5.7, respectively. The results of two different sets of structural groups derived from the Joback group contribution approach are tested and compared. The method is notable for the absence of any theoretical procedure which has previously been used to estimate the pure-component octane number. In addition, the method has the potential advantage of synthesis of additional hydrocarbons with knock measurements as a major objective.


The act of moving a running virtual machine (VM) from one physical host to another, without interruption to its services or resulting in downtime, is called virtual machine migration. Live virtual machine migration (LVMM) is a vital component of cloud computing that enables scalability, reliability, and load balancing capabilities in virtualized environments, with no apparent downtime for the end-user. This research paper outlines several LVMM methods and provide an analysis on the basis of downtime, total migration and total data transfer


Transportation system in a region, act as a vein and also tools to measure the development progress of that particular region, therefore the system growth is usually corelates the growth of other sectors in society, such as economy, social, culture, politics and citizenship, thus the transportation system becomes a deciding factor of a regional growth. A good transportation system is able to ensure the mobility of goods, service and people in an effective, efficient, safe, comfortable integrated and sustainable. One way to achive that is through traffic control, in which the Tololiu Roundabout in Tomohon city as a crossing point that connects Tomohon city and other administrative regions in North Sulawesi, whereas the current roundabout requires data to be able to be adapted with the increasing regional growth. The purpose of this research is expected to describe the existing Level of Service (LoS) of the roundabout and predicts the future condition up to 2022 and able to be used as an accountable data for future growth of Tomohon city. The method applied in this research are literature study, primary and secondary data collection, data analysis using MKJI 1997 method and software simulation using AutoCAD 2017, Microsoft Excel 2016 and Synchro Studio 9,0. AutoCAD used to simplify the roundabout geometric analysis, Microsoft Excel used to calculate the MKJI 1997 RWEAV-I and RWEAV-II form and Synchro studio 9,0 used to create a real-time simulation of the traffic characteritics in the field of study. The result of the MKJI 1997 analysis coupled with the regional demografic data to predict the future condition up to 2022 shows that the Degree of Saturation (DS), exceeded the boundary threshold of 0,75 in the year of 2019 and so is adviced to apply a geometric and/or volume engineered solution. The result of the Synchro Studio 9,0 simulation shows B grade LoS for the existing data of 2015, but exceeded the boundary threshold of DS in US HCM 2010 method in the following year. The different result by the two methods analyses are due to the different parameters incorporated in both method where the US HCM 2010 in Synchro 9,0 is leaning on Delay Control (and more complex parameters) and the MKJI 1997 mothod rely on the Volume and Capacity. Either way, the study and analysis show that the Tololiu Roundabout in Tomohon city is in need of re-engineering in order to adapt to the future regional growth by applying geometric road widening, no-parking zone, volume divertion through the two minors approach available and also a social education of the roundabout rules and regulation coupled with the good-will of the government to provide the neccesarry facility and tools for the roundabout. Keywords: Tololiu Roundabout, Level of Service (LoS), Degree of Saturation (DS), US HCM, MKJI.


The effects of landscape structure and crop management on insect community and associated ecosystem services and disservices within coffee plantations Habitat loss and fragmentation are considered the major threat to biodiversity at global scale. The main driving force behind this process is agricultural intensification that is based on pesticide overuse and expansion of monocultures resulting in landscape simplification as well as loss of species and associated ecosystem services. Despite recognized importance, little is known about how agricultural intensification affects the occurrence of different insect functional groups at multiple spatial scales in the Neoptropical region. The aim of this study is investigate how landscape structure and local factors (e.g. microclimate and pesticides) affect insect community and the provision of ecosystem services and disservices in crop matrix. For this, wasps (natural enemies), bees and flower flies (pollinators) were collected in 16 coffee plantations and in 16 forest fragments located in different landscape contexts in southeast Brazil. Moreover, the abundance of the coffee leaf miner Leucoptera coffeella (pest) and mortality rates related to predation (biological control) were estimated within coffee plantations. Landscape structure was represented by the following metrics: percentage of forest cover, landscape diversity and edge. These metrics were calculated at four spatial scales 250, 500, 750 and 1000 meters in the surroundings 0of coffee-forest interfaces. Over 13 months, we collected 13,658 wasps distributed in 86 species and 26 genres; 8,393 bees belonging to 116 species and 73 genres; and 4,984 flower flies within 63 species and 20 genres. Pest abundance and biological control varied from 5.3 to 32.5 % and from 12.7 to 72.8 %, respectively. Pest abundance was negatively correlated with the increment of forest cover and decreasing temperature. Species richness and abundance of wasps and bee species richness increased with increasing forest cover. The beta diversity of wasps and bees presented high values of nested component between pairs of interfaces located in landscapes with high and low forest cover indicating species loss in structurally simple landscapes dominated by monocultures. These results were found at all spatial scales from 250 to 1000 meters suggesting that forest conservation and restoration can enhance the balance between crop production and biodiversity conservation, and that it should be promoted at landscape scale. Increasing forest cover in crop dominated landscapes can result in higher availability of resources resulting in the high species diversity and provision of associated ecosystem services such as pollination and pest biological control.


Tunable diode laser heterodyne spectrophotometry (TDLHS) has been used to make extremely high-resolution (0.0005-cm−1) solar spectra in the 9.6-μm ozone band. Observations have shown that a SNR of 120:1 for an integration time of ⅛ s can be achieved at a resolution of 0.0016 wave numbers. The measured SNR at 0.0016-cm−1 resolution is ~30% of that theoretically obtain able. The spectral data have been inverted to yield a total column amount of ozone of 311-m-atm-cm compared to a value of 355-m-atm-cm obtained at the nearby National Oceanographic & Atmospheric Administration ozone monitoring facility in Boulder, CO. Line positions are reported for several ozone lines in the 996-997-cm−1 spectral region.


The subject. The authors create an instrumental apparatus that saturates existing and emerging data needs in the theory constituting process and thus create preconditions for police practice development.The methodology. The research is based on the content analyses of final research reports, the object of which is police proceedings and the subject is police reality,The purpose. The authors substantiate the following hypothesis. The source of the development of knowledge in police practice and the development of police theory is a permanent solution to the philosophical contradiction between police theory and police practice, with police practice being the defining aspect of this contradictory unity. The need and areas of scientific knowledge of activities in the police proceedings structure are therefore determined by police practice.The main results. By verifying police practice, the authors confirm the necessary obligatory interaction between theory and practice, which is predominantly determined by the achieved research outputs and their acceptance. At the same time, they respect that systematically processed knowledge from applied research can show the character of a theory. In accordance with their knowledge, consisting of a system of knowledge presented by the achieved outputs from scientific research, evaluation and explanation of phenomena registered in the purposeful implementation of activities in the structure of police proceedings (research object). The term police action can be understood as a synthetic term for a holistic grasp of the police activity and its bodies. The activity of police and security authorities means: a special form of professional service for the state, self-governing as well as commercial organizations and, last but not least, citizens. It contains a set of executive, organizational, management and other activities that have the character of official interventions, official acts, other official activities and other measures. They are carried out in accordance with the rule of law and ethical principles of civil democratic society, preventive and, where necessary, repressive methods of police work. Their aim is to protect the fundamental human rights of citizens and society from crime and other anti-social activities. They define the identity of these phenomena through the subject (optics) of research, systematically defining the police reality by the process parameters, their determinants and constructs of specific police activities. In the Slovak Republic, the authors of this paper participate in the performance of tasks related to the constitution of police sciences. The outputs of applied research offer a system of scientific knowledge about police reality. With the dialectical approach, in relation to the examined activities in the structure of police proceedings, they define the reasons related to the assumption of the existence of links among the elements of police reality, or they reveal their objective absence. By identifying systems, the authors create a model of these purposefully implemented activities with properties characterizing their behaviour. At the same time, they respect that the strategic form of the parameters of this model is expressed by the achieved set intentions and goals of certain specific activities. Determining them is a concentrated expression of this will. The basic context in their work (participation in the process of constituting police sciences), determining the meaning and mission, is a specific subject accepted by them. This is the police reality, an objective fact that the theory of police sciences examines and uses to explain existing and emerging objects. Therefore, their activity in the process of constituting police sciences corresponds to changes in social processes. When creating their instruments (conceptual system, categories, theoretical models, forms of thinking), they combine it with the explanation of new approaches related to the development and advancement of policing processes, characterized by openness and possibilities of social control in their purposeful implementation. This confirms that this process forms a system. Its design shows relative stability and closeness. They do not include any inputs in its content, just those that are foreseen and anticipated. In this context, they realize that the interdisciplinary of concepts enriches the view of constituted police science. For the police sciences , the abstractness and generality of statements from other scientific disciplines is not a starting point, but already the result of research into specific systems (disposition of knowledge), significantly contributing to increase effectiveness of their scientific work. In the conditions of the Slovak Republic, the police sciences are constituted as practical, social and security sciences. Therefore, the authors of this paper accept that the theoretical and methodological development of police sciences requires them to be confronted and independently dealt with the current state in the theory and methodology of science in the early 21st century, to be sensitive to the current development of the overall scientific atmosphere and independently and critically. In this process, the meaningfulness of their scientific work is evident. This corresponds to the registered needs for the transfer of scientific knowledge into police practice.Conclusions. From these findings it is clear that in the current stage of development of the Slovak Republic, the process of constituting police sciences forms a structured system with to the point management. Its successful completion is also determined by the results of a constructive discussion, the authors participated in with this presented knowledge.

Thiosemicarbazones are class of compounds which are obtained by the condensation of thiosemicarbazide with carbonyl compounds. The transition metal complexes of thiosemicarbazones are widely considered due to their broad spectrum of biological activities such as antibacterial, antitumor and antifungal activities. In present research work a series of four novel Cu(II) aryl thiosemicarbazones complexes having the general composition [Cu(L1)2Cl2], [Cu(L2)2Cl2], [Cu(L3)2Cl2] and [Cu(L4)2Cl2]{where L1= 4-nitroacetophenone thiosemicarbazones (4NAT), L2 = 3-nitrobenzaldehyde thiosemicarbazone (3NBT), L3 = 4-hydroxybenzaldehyde thiosemicarbazone (4HBT) and L4 = 4-aminoacetophenone thiosemicarbazone (4AAT)} have been synthesized by the reaction of thiosemicarbazide with substituted aromatic aldehydes and ketones by conventional heating as well as microwave irradiations method followed by complexation with Cu(II) metal. The synthesized compounds have been characterised by elemental analysis, melting point determination, FTIR, UV-visible spectral analysis. Thiosemicarbazone ligands behave as bidentate ligand and forms octahedral complexes with Cu(II). The synthesized ligands and their new metal complexes have been screened in vitro for antibacterial activity against Escherichia coli, Staphylococcus aureus and Bacillus subtilis bacteria. The result shows that all the Cu(II) complexes are potent antibacterial agents against these bacteria.


User-role based security (URBS) has drawn signi cant attention in recent years for its ability to customize security privileges according to the responsibilities of individual user roles. To provide access to object-oriented applications, the public interface of each class contains methods for all potential users of the class. In order to nely tune this access, URBS can be introduced to promote a strategy that controls access on a role-by-role basis, with di erent roles having access to speci c subsets of each public interface based on their responsibilities within the application. Our previous e orts have been working towards such a capability. This paper continues these e orts by investigating approaches for extensible and reusable URBS enforcement mechanisms for object-oriented systems. Such approaches should insulate software engineers from security concerns while simultaneously embedding the URBS policies into compiled applications that then behave di erently based on an individual's role. We consider generic security classes that stress uniformity and encapsulate security details, while promoting software reuse. We also explore exception handling as an vehicle for achieving dynamic role-based behavior in applications. By combining both generics and exception handling, the bene ts of both can accrue in an approach that attains software reuse and software evolution.


Previous studies demonstrated the involvement of transforming growth factor-α (TGFα), a member of the epidermal growth factor (EGF) family, in the developmental regulation of hypothalamic LHRH release. Although both TGFα and EGF stimulate LHRH release, they do not appear to act directly on LHRH neurons, as no EGF/TGFα receptors are detected on these cells in vivo. Instead, the stimulatory effect of TGFα on LHRH release seems to require a glial intermediacy. The present study identifies one of the glial molecules involved in this process. In vitro exposure of purified hypothalamic astrocytes to TGFα or EGF in a defined medium led to activation of the cyclooxygenase-mediated pathway of arachidonic acid metabolism, as indicated by an increase in PGE2 release, but failed to affect lipooxygenase-mediated metabolism, as assessed by the lack of increase in leukotriene C4 production; addition of TGFα- (T-CM) or EGF-conditioned medium to cultures of LHRH-producing GT1-1 cells stimulated LHRH release. In contrast, ...


Urban utility tunnels (UUTs) can have great external benefits in terms of social and environmental aspects for the sustainable development of a city. However, the high initial construction cost has been the main obstacle to the promotion of UUT projects for a long time. Although several evaluation methods for the benefits of UUTs have been proposed, most of them focus on the cost assessment during the construction period and are limited in terms of their scientificity, the feasibility of the valuation methodology and the comprehensiveness of external categories. The external benefit assessment of UUTs during their service life remains lacking, leading to an incomplete insight into UUT projects. Therefore, a scientific evaluation method of the long-term external benefits of UUTs is still needed from the perspective of urban sustainable development. This paper proposes a composite market price method to carry out a simple but systematic evaluation of the positive externalities of UUTs in monetary terms. Detailed instructions on the operation of the method are also elucidated to further improve its practicability. The feasibility and validity of the method is then demonstrated through a case study of the UUT project in Xiong'an New Area, China. It is also concluded that UUTs can benefit all social subjects and that a classification of externalities based on different social subjects can foster better development and broader support for the implementation of UUTs.


The Cana Brava complex is an anorogenic stratiform complex, whose layers dip from 30° to 50° NW. The massif is made up of five units composed of layers containing several associations of cumulus phases and variable amounts of inter-cumulus minerals. Transition between units are characterized by abrupt changes in the composition of these phases. From base to top, the sequence consists of amphibolites (PICB1), overlain by serpentinites (PICB2), metawebsterites (PICB3), and metagabbros (PICB4 and PICB5). This sequence was originally formed by microgabbros, peridotites, websterites, and gabbros. Isotopic data indicate that the parental magma of the Cana Brava complex evolved as follows: (a) Mantle derivation at about 2.5 Ga and subsequent retention at subcrustal levels; (b) Intrusion within the Palmeiropolis volcano-sedimentary sequence and igneous crystallization at about 2.0 Ga; (c) Metamorphism and ductile-ruptile deformation under compression at about 1.3 Ga; and (d) Further metamorphic reequilibration during the Brasiliano Cycle at about 0.77 Ga.


In this study the Navarro fault system is defined based on geologic, geomorphologic, and seismological observations. This fault system is located between the northern slopes of the Talamanca cordillera and the southern and southeastern slopes of the Irazu and Turrialba volcanoes and is characterized by left-lateral displacements. The Navarro fault system trends between east-west and northeast-southwest and includes the following fault segments: Tarrazu, Navarro, Cachi, Urasca, Paraiso, and Maravilla. There are two transtensional structures along the fault system: the step over Estrella and the Ujarras tectonic depression. Earthquakes during 1973-2015 were relocated illuminating the fault segments of the southwest portion of the system. The focal mechanisms calculated mainly correspond to strike-slip faults in agreement with morphotectonic observations.


Significance Programmed death-ligand 1 (PD-L1) expression on tumor cells and tumor-infiltrating immune cells is regulated by distinct mechanisms and has nonredundant roles in regulating anticancer immunity, and PD-L1 on both cell types is important for predicting best response to atezolizumab in non-small cell lung cancer. Programmed death-ligand 1 (PD-L1) expression on tumor cells (TCs) by immunohistochemistry is rapidly gaining importance as a diagnostic for the selection or stratification of patients with non-small cell lung cancer (NSCLC) most likely to respond to single-agent checkpoint inhibitors. However, at least two distinct patterns of PD-L1 expression have been observed with potential biological and clinical relevance in NSCLC: expression on TC or on tumor-infiltrating immune cells (ICs). We investigated the molecular and cellular characteristics associated with PD-L1 expression in these distinct cell compartments in 4,549 cases of NSCLC. PD-L1 expression on IC was more prevalent and likely reflected IFN-γ–induced adaptive regulation accompanied by increased tumor-infiltrating lymphocytes and effector T cells. High PD-L1 expression on TC, however, reflected an epigenetic dysregulation of the PD-L1 gene and was associated with a distinct histology described by poor immune infiltration, sclerotic/desmoplastic stroma, and mesenchymal molecular features. Importantly, durable clinical responses to atezolizumab (anti–PD-L1) were observed in patients with tumors expressing high PD-L1 levels on either TC alone [40% objective response rate (ORR)] or IC alone (22% ORR). Thus, PD-L1 expression on TC or IC can independently attenuate anticancer immunity and emphasizes the functional importance of IC in regulating the antitumor T cell response.


Objective: To prepare chitosan nanoparticles carrying gene,study its transfection efficiency and immunological enhancement in mice. Methods: The nanoparticles was based on the foot and mouth disease DNA vaccine, and was prepared by complex coacervation. Its morphology was observed by transmission electronic microscopy (TEM). Particle size, polydispersity and zeta potential were determined by nanoparticle size analyser. The molecular localization of pDNA in the chitosan nanoparticles was determined by gel retardation assay. Transfection efficiency of pDNA-chitosan nanoparticles was determined by gene transfection experiment in vitro. Balb/c mice were immunized by pDNA- chitosan nanoparticles to test both humoral and cellular immune responses. Results: The morphology of the nanoparticles were mostly spherical. The average particle size was 150nm, and the polydispersity of particle size0.26,the zeta potential of the nanoprticles was 21 mV. The results of gel retardation showed chitosan could completely combine the pDNA by electronic combination and pDNA was mostly encapsulated within the nanoparticles.The gene transfection experiment in vitro showed that the pDNA-chitosan nanoparticles can transfect BHK celles, and the gene can express in these celles. Immunity test proved that the nanoparticles not only induced high cellular immunogenecity, but also induced a good humoral immunogenecity in mice. Conclusion: chitosan nanoparticles can deliver gene into cell and express in these celles. Immunity test proved that it has favourable immunological enhancement.


A new intermodal transport link with vertical transhipment of semi-trailers now connects the terminals in Lovosice (Czech Republic) and Hamburg-Billwerder. The service operates three times a week with three merry-go-round train pairs, helping relieve the overburdened road link and reducing environmentally harmful emissions. The article also looks at the potential for shifting a larger share of road traffic to rail using the ModaLohr or CargoBeamer systems and assesses their economic prospects.


It was found that cobalt supported on active carbon showed an excellent catalytic activity for the carbonylation of dibromo methane in the liquid phase. For example, when the reaction was conducted under the conditions of 140 °C, P(CO) = 31 atm, the yields of dimethyl malonate and bromomethyl acetate were 34.4% and 22.2%, respectively. Pd and Rh also showed catalytic activities.


Author(s): Choe, Ronny C. | Advisor(s): Glanzman, David L | Abstract: Prepulse inhibition (PPI) in larval zebrafish can be utilized as a behavioral marker for neural dysfunction. In this study, we show that application of pharmacological agents to affect the Mauthner Cell mediated startle movement in response to acoustic stimuli can be used to quantify dysfunction. By establishing a robust protocol, we were able to confirm the effects of numerous pharmacological agents on PPI. We were also able to establish that haloperidol had a negative effect on PPI. This parallels some recent mammalian PPI studies that indicate that haloperidol has mixed effect on PPI. Dose dependent effects, timing, and even the nature of the reductionist zebrafish model may be responsible for this difference. However, the large sample sizes and simple neural circuitry makes the larval zebrafish and excellent model for high throughput screens of psychotropic therapeutic agents.

IF SO, can we not more effectively increase, aid and develop them ? What can we discern and apply towards such ends ?—and learn from biologists, psychologists, and from eugenists ? What have educationalists to say in this matter ? And economists ? And what of the various respective methods of diagnosis, and policies of encouragement ? What have the sociologist and social psychologist, the moralist and the philosopher further to say of these matters ? What can we learn from biographies of men and women of talent and genius, past and present ? What of the general public, in its various occupational and social classes, its political parties and religious denominations ? What, too, of their respective Elites, among all of which there are so obviously men of talent, and sometimes of genius. And as these are so diversified, can we not learn something from each .'


Phytochemical investigations on the chloroform and ethyl acetate soluble fractions of the roots of the Daphne oleoids led to the isolation of the coumarin glycosides 1–6. Compound 5 with IC50 values 22.05 and 26.30 μM repectively, was found to be the most active of these compounds when screened against Bacillus pasteurii and jack bean urease enzymes in a concentration-dependent fashion.


The weighted least squares approach to phase unwrapping, an extension of the unweighted least squares approach, is a robust and accurate method for phase unwrapping. This approach zero-weights portions of the phase data to avoid unwrapping across regions of corrupted phase, which are typically caused by the SAR phenomena of layover and radar shadow. Recently the first practical method for accomplishing this weighted phase unwrapping was introduced. This method is based on preconditioned conjugate gradients (PCGs). We present a new method that is an extension of our multigrid algorithm for unweighted least squares phase unwrapping. This new method features a carefully defined operator for transferring the phase weights to the coarse grids of the multigrid scheme. The algorithm converges in only a few multigrid cycles, and on phase data that contain severe discontinuities or shear we demonstrate that it is up to 25 times faster than the PCG algorithm. We also present methods for defining the initial phase weights, thus yielding a completely automated algorithm for fast and accurate phase unwrapping.

We propose a novel Coordinate Rotation Digital Computer (CORDIC)-based architecture of the Triangular Systolic Array for QR-Decomposition (QRD) of large-size complex matrices. The proposed architecture relies on QRD using a three angle complex rotation approach that provides significant reduction of latency (systolic operation time) and makes the QRD in such a way that the upper triangular matrix R has only real diagonal elements.


Several studies indicate that unregulated nautical tourism can have negative implications on cetacean behaviour. In recent years, dolphin watching activities (DWA) have increased off the West coast of Istria, Croatia, a region in which the NATURA 2000 site: 'Akvatorij zapadne Istre' has been proposed to be designated for bottlenose dolphins (Tursiops truncatus M.). For data collected between 2016 and 2019, we compared dolphin group behaviours from this region during impact (presence of nautical tourism boats (NTBs)) and control (absence of NTBs) scenarios, as well as providing descriptive analysis on the displacement of individuals in the presence of NTBs. Throughout the study years, 48.5 % of NTBs were observed within 15m of the dolphin focal groups and 97 % were observed within 50 m distance. The greatest rates of displacement in dolphin focal groups occurred when NTB numbers were greatest per individual dolphin. Markov chain analysis were used to quantify the short-term effects of NTB presence on dolphin behaviour. In the presence of NTBs, dolphins were more likely to spend time milling and less time foraging. Cumulative behavioural budgets, derived by accounting for the time bottlenose dolphins spent in the presence or absence of NTBs, indicated that vessel exposure levels of 14 % and 25 % were enough to statistically affect milling and foraging behaviours respectively. To lessen the lack of sustainable DWA, the implementation of relevant guidelines, e.g. Global Best Practice Guidance for Responsible Whale and Dolphin Watching (50 m no approach and 300 m caution zone) is therefore crucial to mitigate any long-term consequences the actions of NTBs may have on this key species. To date, 162 bottlenose dolphins have been photo-identified off West coast of Istria and cumulative interference to this population could affect direct ecosystem functioning.

4582 Background: Although it is well known that the quantity of specific immune cell types can provide prognostic information in bladder cancer, only little is known about the prognostic relevance of the localization of immune cells within the tumor microenvironment. Methods: To study the spatial interplay of different immune cell subpopulations and its prognostic role in bladder cancer, 2463 urothelial bladder carcinomas were immunostained with 21 antibodies (i.e., TIM-3, PD-L1, PD-1, CTLA4, CD3, CD8, CD4, FOXP3, CD20, CD68, CD163, CD11c, panCK, Ki67, CD31, Vimentin, HLA-DRa, Myosin-11, Desmoglein 3, PAX-8, and CDH16) using BLEACH&STAIN multiplex fluorescence immunohistochemistry in a tissue microarray format and analyzed using a framework of neuronal networks for image analysis. Thus, Spatial immune parameters were compared with histopathological parameters and overall survival data. Results: The identification of more than 300 different immune cell subpopulations and the characterization of their spatial relationship resulted in numerous spatial interaction patterns. 32 immune parameters showed prognostic significance in univariate analyses of which 16 were independent from pT, pN, and histologic grade in muscle-invasive bladder cancer. The strongest association to clinical outcome was identified for intraepithelial CD8+ cytotoxic T-cells (AUC: 0.70) while stromal CD8+ cells were less relevant (AUC: 0.64, p=0.016). A favorable prognosis of inflamed cancers with high levels of "exhaustion markers" suggests that TIM3, PD-L1, PD-1, and CTLA-4 on inflammatory cells do not hinder anti-tumoral immune response in tumors rich of tumor infiltrating tumor cells. Conclusions: The density of intraepithelial CD8+ T-cells was the strongest prognostic feature in muscle-invasive bladder cancer. Given that tumor cell killing by CD8+ cytotoxic T-lymphocytes through direct cell-to-cell-contacts represents the "terminal end route" of anti-tumor immunity, the quantity of "tumor-cell adjacent CD8+ T-cells" may constitute a surrogate for the efficiency of cancer recognition by the immune system that can be measured straightaway using conventional brightfield IHC in routine pathology as the CD8 labelling index.


We concentrate on the quasi-coincidence of a fuzzy interval value with an interval valued fuzzy set and introduced the notion of an i-v (∈,∈∨ q) fuzzy ternary subsemiring and an i-v (∈,∈∨ q) fuzzy ideals in ternary semirings which can be regarded as the generalization of i-v fuzzy ternary subsemiring and interval-valued fuzzy ideals in ternary semirings.We concentrate on the quasi-coincidence of a fuzzy interval value with an interval valued fuzzy set and introduced the notion of an i-v (∈,∈∨ q) fuzzy ternary subsemiring and an i-v (∈,∈∨ q) fuzzy ideals in ternary semirings which can be regarded as the generalization of i-v fuzzy ternary subsemiring and interval-valued fuzzy ideals in ternary semirings.


Abstract : The relations of leadership style and behavior to work group performance and subordinate job satisfaction have been investigated for 22 first-level and eight second-level nursing supervisors in a Veterans Administration Hospital of 1,680 beds. Nursing assistants supervised by task-oriented (Low LPC) leaders received higher performance ratings at the first level of supervision, while relationship-oriented (High LPC) leaders performed better at the second-level of supervision. Subordinate's job satisfaction was positively related to leader Consideration at both levels of supervision. However, Initiating Structure leader behavior contributed to high subordinate job satisfaction at the first level of supervision but low subordinate job satisfaction at the second level. These differences in effective management patterns are interpreted in the light of apparent differences in situational leadership demands at the two supervisory levels. (Author)

By means of a number of general models the relationships are analysed which are of importance when applying shiftwork systems : for the organization which applies them, its employees, the owners and the community. A quantitative model gives an insight into the shiftwork system which can be regarded as an optimum from an economic angle (depending on the pay level, shift allowances and invested capital). Divergences from the optimum may decrease the rate of return considerably. The outcomes of an analysis of alternatives in a series of companies axe discussed. The approach on the side of companies frequently proves not to be satisfactory. It appears that better information is desirable, with regard to both the economic and the social aspects of shiftwork.


The most Indonesian written manuscripts were written in the Netherlands language. These manuscripts could be accessed by one of the following catalogs: Juynboll Catalogue (1899), Ronkel Catalogues (1909), Riclefs and P. Voorhoeve Catalogue (1977) etc. Unfortunately, the Indonesian researchers have no way to utilize them. According to the international catalogs written in Indonesian and foreign languages, The Malay manuscripts found in Banda Aceh reached about 300 titles. After conducting preliminary research and direct observation to the individual and institutional collectors, it was found that the real numbers of them could reach to a thousand titles of manuscripts that still have separated in various local places. On behalf these facts, the research aims to rescue these manuscripts from a disappearing and extinction by conducting inventory that is predicted to be able to push the Indonesian researchers ahead to discovering their substantial contents that in opinion useful for human life. The output of the research is compiling catalog documents of 1000 titles of Malay manuscripts found in Banda Aceh. The theory and method used in this research are the theory of the codicology and the method of the catalog of manuscripts register. The codicology is subfield studying all of the manuscript's aspects in details such as the place of storing, the owner of the manuscript, the content of the manuscript, etc. Whereas the catalog of a manuscript register is describing all of systematically manuscript's physical and objective aspect in details. The results of the research will be proposed to be the main gate for entering later philology works i.e. presenting and interpreting the text that in turn can be positioned as a manual directive in social and national life.


Objective To explore the clinical value of the virtual endoscope technique in examination and diagnosis of children with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods From July 2006 to December 2010,38 cases of children with OSAHS were enrolled,male 20,female 18,aged 6-7 years old,mean age 6.44 years old,which performed nose pharynx ministry with virtual endoscope.The patients divided into 2 groups,group Ⅰ(n = 18) was merged secretory otitis media and group Ⅱ(n = 20) was without otitis media.The adenoid thickness of the most prominent part,the anteroposterior diameter of nosopharynx,adenoid thickness/the anteroposterior diameter of nosopharynx(A/N) ratio and the depth of lateral sulcus of adenoids were measured with virtual endoscope.Results In group Ⅰand group Ⅱ,the adenoid thickness were(16.21 ± 1.74) mm and(15.75 ± 1.44) mm;anteroposterior diameter of nosopharynx were(19.52 ± 1.37) mm and(19.36±1.27) mm;A/N ratio were 0.85 ± 0.06 and 0.83 ± 0.05 respectively.There were no statistically significant(P 0.01).But the depth of lateral sulcus of adenoids in the group Ⅰ and group Ⅱ were(1.69 ± 0.52) mm and(2.90 ± 0.68) mm respectively,the depth of lateral sulcus of adenoids group Ⅰwas much more shallow than that in group Ⅱ(P 0.01).Conclusion It is demonstrated that the adenoids merger with secretory otitis mediathe is associated with the form of adenoid.The virtual endoscopic technique not only could measure the thickness,but also could evaluate the form of adenoid.The virtual endoscope technique has much more useful in the clinical diagnosis of children with OSAHS and it is worth to introduce.


Banana is a tropical fruit plant that popular in people. The availability of Raja Bulu banana seedling insufficient to cover the needs. Problems in commercial banana cultivation is the least availability of clonal superior seeds. Multiplication in tissue culture technique can potentially overcome all limitations of Raja Bulu conventional seedling. So that, the objective of this research was to multiplicate an amount of Raja Bulu banana shoot using plant growth regulator in MS medium to initially produce shoot organs. The multiplication was done by Completely Randomized Design with 2 factor of IAA (0; 0,5; 1 ppm) and BAP (0, 2, 4 ppm). The data were analyzed by ANOVA and the mean compared using Duncan's pairwise comparisons at p = 0,05. The acclimatization was design by Completely Randomized Block Design with 3 different media of palm fiber, bagasse, and banana pseudo stem then analyzed by ANCOV. The results showed there was interaction of IAA and BAP on variables at the appearance of shoots and the leaf appearance in multiplication. The medium without IAA and contained BAP 2 ppm showed the highest mean number of shoot but it was not cost effective with other treatment in this multiplication. Giving IAA 0,5 ppm with BAP 4 ppm accelerated when the shoots appear and when the leaves appear on multiplication Raja Bulu banana. There was no significant interaction or influence of IAA and BAP on plant height, leaf number, and pseudo stem diameter as acclimatization variable with 3 medium used. The percentage of acclimatization success is 76,5%.


The article analyses the principles of personnel policy implemented in the Altai Control Department at the beginning of the 20th century. Reconstructing the personal of the institution on the basis of the array of personal files of the Department officials, the author compares their staff tables. The 1899 staff provided officials promotion opportunities and gradual training of specialists in grass-roots positions with subsequent promotion. But the lack of promotion prospects for comptrollers could slow down both of these processes. Therefore, the stable position of comptrollers "frozen" personnel movements, which increased only during periods of extraordinary situations in the work of the department. The new staff of 1913 provided some opportunities for personnel dynamics, generally preserving the basic principles of the previous staff. Also at the beginning of the 20th century there was a change of generations of employees of the Altai Control Department. The author concludes that, depending on the conditions and the tasks before the establishment, various possibilities of implementing the staff could be used to create the most stable and workable team of employees of the Altai Control Department.


Experimental studies of radiofrequency renal denervation (RDN) have shown a strong relation of the depth of structural lesions and completeness of renal nerve injury to the relative drop in impedance during the treatment caused by the increased permeability of the cell membranes. Thus, the otherwise successful treatments but with low impedance drop may be, in fact, totally ineffective.

 We assessed the relation between impedance drop during single radiofrequency treatments and local structural changes of vascular wall at the electrode positions using optical coherence tomography.

 Optical coherence tomography of the treated segments was performed during radiofrequency RDN in 14 patients with resistant hypertension. The parameters of contrast injection depended on the position of the guiding catheter: for selective branch imaging 15 ml volume was injected at 8 ml/sec speed; otherwise 30 ml of contrast was injected at the speed 15 ml/sec to flush the whole renal artery. Automatic pullback of the sensor was done with the standard speed 20 mm/sec. In total, 423 mm of treated segments in 22 renal vessels (mostly distal branches) had sufficient quality of imaging and were studied for structural changes.

 There was almost no local structural changes of the arterial wall after the treatments with low impedance drop <10% reflecting a rather weak heating of even superficial tissue layers. No effect on the deeper tissue layers is expected in this case because these layers are heated almost exclusively by the heat transfer from superficial layer. In contrast, the treatments with the impedance drop 10% or greater were able to significantly affect the arterial structure causing local edema, small dissections, and local thrombi formation as a result of significant resistive heating of the superficial tissue, and, therefore, high potential for heating of the deep layers containing the renal nerves. Only approximately 40% of the point treatments had the impedance drop 10% or greater suggesting adequate lesion depth and sufficient completeness of renal nerve injury. This may indicate a rather low procedural efficacy of the current mode of radiofrequency RDN due to a large proportion of small-depth treatments marked by only a few percent decrease in impedance yet considered fully "successful". Also, it means a potential for significant increase in the efficacy of radiofrequency RDN through controlling/guiding the treatment by the impedance drop.

 Our study shows that variable efficacy of radiofrequency RDN may be explained by a significant proportion of the small-depth point treatments ineffective in terms of renal nerve injury, and, thereby, may be significantly improved if the procedure is guided by the impedance drop during the treatment.

Intra and inter-speaker variability is studied as a way to better understand how voice can be used as biometric data. Formant values from 328,016 exemplars of the 10 French oral vowels uttered by 111 speakers were compared to estimate their speaker discrimination power. The vowels /œ/, /ɛ/ and /a/ appear to convey more idiosyncratic information than other oral vowels. A more comprehensive phonetic analysis is carried out for each speaker on 2 samples leading to either high or low discrimination performance when used in the Alize/spkDet SVS. However, no direct explanation can be drawn from phonetic measures to predict


The following paper aims at shedding some light on Albanian language case system with special focus on the assignment of accusative case. As a member of the vast Indo-European family Albanian language is characterized by an inflected case system and as so a free word order. Traditionally, we are taught and we still teach to the coming generations that accusative case is assigned mostly by the verb to that sentence noun phrase syntactically representing the direct object and semantically introducing the Theme or the Patient.   Moreover in Albanian accusative is also assigned by another morphological category bearing the distinctive features [+noun;+verb], namely the preposition. Furthermore, as a researcher in the field of generative syntax I have a stake at analyzing certain exceptional cases of accusative case assignment to the subject NP of the Albanian subjunctive clause. In conclusion, I was really tempted to adopt Chomsky's reconciling proposal in accusative case assignment under the specifier-head structural and schematic relation.


1. Fifty-six patients were treated with amphetamine sulfate during the early post-intoxication period of the acute alcoholic cycle. The cycle was interrupted in 49 cases, with 7 patients failing to respond satisfactorily. The cycle was not interrupted in the control group treated with placebos. 2. It was found that physical and mental "hangover effects" were markedly reduced by amphetamine sulfate in doses of 10 milligrams. 3. A marked improvement in awareness, sensory perception and activity drive was observed soon after treatment. 4. Mood and rapport were improved, patients demonstrating greater cooperation, increased accessibility and decreased negativism, thus facilitating the initiation of a rehabilitative program.


This study was designed to answer the following four research questions. Firstly, it aims to identify optimal brand experience of G-Star game show and trade for inducing visitors' transportation. Secondly, it examines the relationship between transportation, convention loyalty, and purchase intention. Thirdly, it investigates the moderating role of visitors' involvement in the relationship between brand experience and transportation. Fourthly, it investigates the moderating role of consumers' innovativeness in the relationship between transportation and convention loyalty. Moreover, it examines the moderating role of consumers' innovativeness in the relationship between transportation and purchase intention. Based on the existing theoretical backgrounds, four brand experiences in convention were derived. The proposed conceptual model was empirically tested via a structural equation modeling analysis using data collected from 331 visitors. The study results show that three types of brand experience in convention are crucial factors in the formation of visitors' transportation. And transportation has positive effects on convention loyalty and purchase intentions. This study indicates that consumers' involvement moderates the relationship between behavioral brand experience and transportation. Consumers' innovativeness moderates the relationship between transportation and convention loyalty. The critical theoretical and managerial implications of findings are discussed in the article.


Analogy to the method of active contours is presented for the problem of form recognition in the case when etalon objects are described in terms of flexible object, while test objects are closed 1-connected domains.


III- method of manufacturing a nitride-based semiconductor device includes: (a) a step of growing the semi-polar or non-polar GaN-substrate or on one or more of the buffer layer thereon, which includes the buffer layer are the semi-polar or non-polar III- Nitride buffer layer phase, and (b) a step of doping said buffer layer, one or a number of crystal defects in the III- nitride device layers formed on the doped buffer layers or on or more of the undoped buffer layers in or on so that not more than the number of crystal defects in the III- nitride device layers formed on a step of doping of the buffer layer. The doping may reduce or prevent the formation of potential miss-fit lines and additional threading dislocations. The thickness and / or composition of the buffer layer is a buffer layer that may be determined to have a greater thickness near or on their critical thickness for relaxation. In addition, one or more (AlInGaN) or III- nitride device layers can be formed on the buffer layers or on top of it.


Many colonial invertebrates settle and grow beside conspecific individuals. As a result tissues of different individuals come frequently into direct contact with each other. Self/non-self recognition mechanisms are known in a number of colonial animals from different phyla including sponges, cnidarians, bryozoans and tunicates. These mechanisms control rejection or fusion of adjacent tissues that come into contact with each other. Many studies have documented the existence of naturally occurring chimeras in these phyla and it has been proposed that several types of ecological and biological benefits accrued to these chimeric colonies. The present paper summarizes past results from field and laboratory studies on the outcomes of natural conspecific-fusions in a reef branching coral Stylophora pistillata (Cnidaria) and a colonial tunicate Botryllus schlosseri (Protochordata). These two species represent two different types of natural chimeras, sectorial and cytomictical (mixed cell) chimeras, respectively. In a fused pair of corals, photosynthetic metabolites are translocated from the "inferior" colony to the "superior" one, which utilizes these products for its metabolic requirements. A significant decline in both somatic and germinal development usually results. After a long period of fusion one of the partners in the chimera (usually the subordinate) dies. Similarly, after somatic fusion in Botryllus colonies, a complete resorption of one of the chimera is often the result. Death of one of the fused colonies often subsequently led to the death of the other colony. In some cases eggs of one colony were transferred and brooded within the developed zooids of the second colony of the pair . B. RINKEVICH AND I.L. WEISSMAN We suggest that chimerism in invertebrates may present substantial fitness costs, and involves an array of competitive interactions between the two partners. These include cell lineage competitions and competition for energy resources. If the alternate suggestion is that chimeras between closely related organisms is advantageous, such chimeras should be abundant in nature. This is not yet documented. We therefore propose that chimerism in the invertebrates is characterized by somatic and germ cell parasitism rather than synergistic symbiosis and other benefits.


The Fisher information matrix summarizes the amount of information in a set of data relative to the quantities of interest. There are many applications of the information matrix in statistical modeling, system identification and parameter estimation. This short paper reviews a feedback-based method and an independent perturbation approach for computing the information matrix for complex problems, where a closed form of the information matrix is not achievable. We show through numerical examples how these methods improve the accuracy of the estimate of the information matrix compared to the basic resampling-based approach. Some relevant theory is summarized.


1. This paper reports a study of the behaviour of five strains of ryegrass (Devon Eaver, Irish S. 24 and New Zealand certified mother perennial ryegrass and H.I) under three different conditions of spacing and two types of management. Strain performances are compared on the basis of green and dry-weight data of total herbage, and green weight of sown strain contributions under the three techniques of evaluation. 2. Under both managements, the total annual production per unit area was greatest from broadcast and least from single-plant areas. Some individual cut yields were, however, greater than those from broadcast plots, with the drill-row production intermediate. 3. Yield differences between the four perennial ryegrasses were greatest as spaced plants and least in broadcast plots. Single plants and broadcast plots of H. 1 were outstanding compared with the perennial strains. Under neither management were there significant interactions between strains and sowing method in 1952, though such interactions were detected in both cases during 1953. 4. The relative yield performance of strains under similar spacing conditions were almost identical under both managements.


A hearing aid having a microphone (10), a microcomputer (12) for digital signal processing of digitized microphone signals and an electroacoustic converter (14) for acoustic reproduction of the processed digitized signals, is equipped with at least one further sensor (16, 18) responsive to signals outside the acoustical range of audibility. These further sensor signals are processed according to a different program stored in a second memory (19) and supplied as additional data via an output (B2) of the microcomputer (12) preferably to the electro-acoustical converter (14). As a result, data such as the signals of a traffic light transmitter, signals from a paging system, or signals announcing a telephone call, door bell or the like, can be superimposed on the normal auditory functions. By appropriately coordinate signal trains, for example generated in accordance with the program stored in the second memory, a hearing-impaired person can easily distinguish among these additional functions.

Royan Institute Interna-tional Summer School on Developmental Biology and Stem Cellswas held at the Royan Institute in Tehran, Iran (Figure 1). Thisextensive Summer School was devoted to the germ cell cycle andepigenetics and covered subjects such as mammalian preimplan-tation development, gastrulation, formation of the germ lineage inmammals and the accompanying epigenetic programming. Thisfirst Summer School was a great success with around 200students (MSc and PhD), mostly from Iran. It was enjoyable forstudents, teachers and organizing staff alike, and the idea is tohave an annual follow-up focused on other themes in develop-mental biology.In reality, the organizing committee experienced difficulty infinding international lecturers. Indeed, when we [B.R. and S.C.]were invited to lecture at this Summer School, our emotions weremixed between being honored, curiosity and admittedly alsosome form of anxiety. After all, there are certain laws or religiouscustoms in Iran that westerners are not used to or disagree with.Other customs can be rather uncomfortable, such as wearing ahead scarf and long-sleeved manteau (a kind of trenchcoat) whichis compulsory for women. Colleagues replied in a similar fashionwhen we spoke about the Summer School. "Iran, but isn't thatdangerous!?" and "Are you sure you want to go there?" were themost heard comments. Before our visit to Iran, we also visited thewebsite of the Dutch Ministry of Foreign Affairs for travelling tips.The advice was clear: "code 5" meaning "only visit the countrywhen strictly necessary" which made us seriously consider can-celling the visit. Our families and friends were also apprehensiveregarding our decision to accept the invitation. But we weredetermined to go and we were looking forward to spending timeteaching and discussing our favorite themes: germ cell develop-ment, stem cells, epigenetics and early embryonic development.And this we found was the right decision; we encountered ahospitable and modern institute that hosted the Summer School,and the participating students were all highly motivated andenthusiastic. To our relief, both men and women were part of theorganizing staff, and both male and female students participated.Men and women contributed equally to the discussions betweeneach other and with the teachers. As a bonus, the cultural heritageof Iran is of jaw-dropping beauty and we had the opportunity toexperience at least some of the highlights. We hope that in thenear future more scientists accept the invitation to visit andparticipate in scientific events in Iran.

A maximum-likelihood receiver (MLR) is synthesized, and asymptotically exact expressions for detection and estimation of the unknown arrival time of the random pulse are derived. The efficiency of the synthesized receiver and the applicability limits of the derived expressions are determined with the help of computer statistical simulation.


Anomaly like central cusp is accessory cusp which is similar to Dens Evaginatus (DE) in premolars. Such accessory occlusal/central cusps are rarely being reported in mandibular molars. The presence of these structures can be a cause of concern when they interfere with occlusion, get fractured or pulp is exposed. This report presents an unusual case of 21-year-old male patient with bilateral accessory cusp in permanent mandibular second molars, the left with Occlusal central cusp (7-cusp anatomy) and the right with a prominent expression of tuberculum sextum (5-cusp anatomy). The patient reported with sensitivity on lower left second molar. Radiograph did not reveal any pulpal extension in both the teeth. Buccal caries on left second molar was restored with composite resin and the accessory cusp was incrementally grinded. The patient reported on follow-up visit after 6 months and was asymptomatic. Early identification of supernumery occlusal central cusp and proper treatment can avoid pulpal complications.


Some dynamical behaviors of fractional-order commutative quaternion-valued neural networks (FCQVNNs) are studied in this paper. First, because the commutative quaternion does not satisfy Schwartz triangle inequality, the FCQVNNs are divided into four real-valued neural networks (RVNNs) through quaternion commutative multiplication rules. Furthermore, several types of dynamical behaviors including global Mittag-Leffler stability, the boundedness with bounded disturbances, complete synchronization and quasi-synchronization of FCQVNNs are studied. Simultaneously, several conditions for these dynamical behaviors are driven by fractional-order Lyapunov direct method, some inequality techniques and fractional differential equation theory. At last, the effectiveness and feasibility of the obtained theoretical results are verified by several numerical simulation examples.


Some scenarics in partioning/transmutation operations require the separation of americium from curium for transmutation of the former element while storing the latter for subsequent use. Aqueous processes for such separations have been utilized for several decades, and modifications of these are currently being used to separate macro quantities of these elements. Improvements in the separation process can be realized by incorporating in-line monitoring of the process conditions through fiber optic spectrophotometric techniques and using advanced ion exchange media. Current developments in these areas along with the dominant physical and chemical factors will be presented.


"There are living systems; there is no living matter", Jacques Monod.1 Dental practice system is a framework that is based on the belief that teeth's ultimate treatment can be best chosen in the context of intervening relationships between themselves and between them and other systems, such as the periodontal system and the facial system, rather than in isolation. The question that keeps on bursting is: which is the best to choose between root canal retreatment and implants without misleading the patients? In this paper, an attempt is made to answer this query. Many previous studies have been carried out, and various authors, mostly endodontists (Cohen et al. 2005), reported that the survival rate of implant and endodontic retreatment are both the same.2,3 However, the latest findings, related to this subject, were mainly directed to the consideration of patient needs and clinical expectations.4


Benign cystic mature teratomas are the most common variant of ovarian germ cell tumors (OGCTs) accounting for more than 95 percent of ovarian teratomas and is almost invariably benign. Malignant transformation occurs in 0.2 to 2 percent of dermoid and comprise of 2.9 percent of all malignant OGCTs. A 58-year-old postmenopausal lady presented with adnexal mass. Her CA-125 was 123 U/ml, CEA-1.71. Ascitic fluid cytology was negative for malignancy. CT scan showed left adnexal mass 5.8x5.2 cm and ascites was present. After surgical staging, a diagnosis of moderately differentiated squamous cell carcinoma in dermoid cyst of left ovary FIGO stage 1C2 was made.


This review describes new engineering solutions for Ti:Sapphire lasers obtained at Laseroptek during the development of laser devices for dermatology and aesthetic medicine. The first device, PALLAS, produces 311 nm radiation by the third harmonic generation of a Ti:Sapphire laser, which possesses similar characteristics to excimer laser-based medical devices for skin treatments. In comparison to excimer lasers, Ti:Sapphire laser services are less expensive, which can save ~10% per year for customers compared to initial excimer laser costs. Here, the required characteristics were obtained due to the application of a new type of diffraction grating for spectral selection. The second device, HELIOS-4, based on the Ti:Sapphire laser, produces 300 mJ, 0.5 ns pulses at 785 nm for tattoo removal. The characteristics of HELIOS-4 exceed those of other tattoo removal laser devices represented in the medical market, despite a simple and inexpensive technical solution. The development of the last laser required the detailed study of a generation process and the investigation of the factors responsible for the synchronization of the generation in Ti: Sapphire lasers with short (several millimeters) cavities. The mechanism that can explain the synchronization in such lasers is suggested. Experiments for the confirmation of this concept are conducted and analyzed.


Under the present large-scale and multi-tier patterns of postgraduate training,it is an imperative to establish a scheme to promote students' academic integrity.A comprehensive education should be provided to foster high moral values as well as professional competence with an integrated framework to facilitate the accomplishment of the objectives.


Background:
In a perfect world, a company would not have to keep any cash at all but because of market imperfections created by information asymmetries and agency problems it has to. Previous research has suggested that a firm's cash holding level is related to its size, growth opportunities and leverage. The Swedish market is particularily interesting to study from a corporate governance perspective, due to a number of specific features such as family ownership, dual class shares, and foreign listing of major companies. Purpose:
The purpose of this study is to investigate the cash holding behaviour among Swedish firms and to study how different corporate governance variables impact cash holdings.
Method: A quantitative approach using regression analysis have been used. Results:
Swedish firms hold more cash than firms from other nations. The cash holding behaviour of Swedish firms is larglely similar to that of firms from other nations, in that size and leverage are highly influential. Further, foreign listing and insider holdings mitigates cash holdings, suggesting a decrease in information asymmetries. In contrast to previous studies, we show that CEO presence on the board decreases the cash holdings of a firm. Conclusions: Corporate governance influence cash holdings of Swedish firms, but not in ways previously suggested by studies made on other countries. The impact of family ownership is beneficial to shareholders and the debate regarding dual shares is overrated.


Communication Constructs That Influence Information Technology Project Failure by Vanessa Mackey MISM, Walden University, 2010 BS, University of Arkansas at Pine Bluff, 1977 Dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Management Walden University May 2015 Abstract Ineffective communication behavioral constructs in the workplace that lead to information technology (IT) project failure and in some cases organization failure are increasingly becoming a management concern. Despite this trend, there is little research on the communication behavioral constructs that contribute to IT project failure rates. The purpose of this phenomenological study was to explore the lived experiences ofIneffective communication behavioral constructs in the workplace that lead to information technology (IT) project failure and in some cases organization failure are increasingly becoming a management concern. Despite this trend, there is little research on the communication behavioral constructs that contribute to IT project failure rates. The purpose of this phenomenological study was to explore the lived experiences of business analysts, programmers, and programmer analysts pertaining to the behavioral constructs associated with effective and ineffective communication. The research questions addressed these behaviors from a conceptual framework based on communication theory, organizational information processing theory, and critical social theory. This framework guided data collection using electronic interviews of a snowball sample of social media participants. Data were coded using open and axial techniques, analyzed for themes and patterns, and member checked to bolster trustworthiness. Findings included 10 communication behavioral constructs that influence communication in IT software development teams. Included in the findings were potential options for improving communication among end users, management, programmers, and other employees. Recommendations to improve communication among stakeholders included involvement of the correct stakeholders, clear project requirements, frequent communication, active listening, and feedback. Other recommendations were stakeholder education and training, and knowledge of goals and processes. Implications for positive social change could be realized by using the findings to improve the way communication is addressed, shared, and implemented to reduce IT project failure for stakeholders.

The crew explored radiation exposure in space ahead of the 4th of July holiday. The astronauts also sent down an Independence Day message as the station nears 20 years of continuous human presence.


The construct of Self-regulated Learning has been conceptualized as the process through which the activities directed by goals are instigated and sustained so that learning is conscious, deliberate and expert, which must constitute one of the main objectives that every educative system should develop in their students. In this work, we intend to determine, first, if there exist significative differences in reported self-regulation of learning among university students with regard to the gender. Second, prove which are the motivational variables that predict better an optimal level of self-regulated learning with respect to the gender differences. The results show, fi rst, that the woman displayed signifi cantly higher self-regulated learning. And second, a different contribution of the studied motivational variables with respect to students´ gender.

Genetic programming is a new technique for machine learning, program induction and optimization loosely based on an evolutionary paradigm. Genetic programming is easily amenable to parallel computing which help relieve the intrinsic slowness of the approach. We describe a parallel implementation of genetic programming on the T3D computer. We apply the system to a problem of induction of binary decision diagrams used in logical circuit design. It is shown that the results depend in a critical way on the representation of the decision diagrams and that the parallel implementation is able to find the correct solution with less computational effort than the sequential version.


During the past five or six years, practically all of the American cable manufacturers have made some changes in their impregnating compound to produce cable having a low dielectric loss. In a number of cases, these compounds were not well chosen. During the same period, some of the operating companies have reduced the thickness of their insulation, resulting in increased dielectric stresses. In a number of cases the compounds, and perhaps also the paper that was used, developed faults that were more serious than high dielectric loss. Some cables have been very deficient in dielectric strength and others have developed a new type of trouble which has been termed "ionization;" after a comparatively short time, the operating voltage of such cable had to be materially reduced or the cable replaced, in order to keep the lines in service. The cable manufactured during this period has generally passed, with a wide margin, the high-voltage tests required by the specifications. Occasionally a lot of cable which passes these tests by a narrow margin will be shipped by a manufacturer and, in such cases, the service record of the cable is unsatisfactory. The investigations which form the basis of this paper consist of, (a) laboratory tests to determine what high-voltage tests cable, known to be of good quality, will withstand; as well as similar tests on other grades of cable, (b) A careful examination and dissection of samples of the cable as received from the factory and samples removed from lines which have failed in service or which have been in service for a number of years without failure, (c) A comparison of the operating records of the cable with the results of the dissection and examination of the samples and with the factory inspection and tests made on the cable before shipment, (d) Accelerated life tests on long samples of cable having a wide range in quality. The results of these investigations have been correlated in a manner which permits of the determination of the relative quality of several lots of cable purchased, as well as changes in the specifications which must be made in order to secure satisfactory high tension cable with impregnated paper insulation.
