Comparative Anatomical, Histological and Histochemical Study of the Liver in Three Species of Birds

The aim of this study is to determine the anatomical features and histological structures as well as some histochemical aspects of the liver of three species of birds that differ in their nutrition, habitat and classification, by using light microscope. The birds were Larus canus, Agaporins fischeri and Numida meleagris. The results showed that the liver of the three species of birds was a dense, large and bilobed organ, it differed in size, color, lobes shape and presence of secondary lobes among the three species. The liver tissue of the three species consisted of hepatocytes which were radially arranged around the central veins interconnecting laminae of one to two cell thickness. The hepatocytes differed in size among the three species. Lumen of sinusoids contained mainly erythrocytes, macrophages and lining by the Kupffer cells. Histochemically, the hepatic cells in the three species of birds were weakly positive to periodic acid Schiff and alcian blue reactions, while they were negative to bromophenol blue reaction and they were moderately positive to Sudan black B reaction.
On Cournot-Nash equilibrium distributions for games with a nonmetrizable action space and upper semi-continuous payoffs

We report results on the existence of a Cournot-Nash equilibrium distribution for games in which the action space is not necessarily metrizable and separable and the payoff functions are not necessarily continuous. Our work relies on the theory of Radon measures as developed by Schwartz-Topsoe and on the epitopology as developed by Dolecki-Salinetti-Wets
Nanohole plasmons in optically thin gold films

The optical properties of single nanoholes in optically thin (t = 20 nm) gold films on glass have been studied experimentally and theoretically. The measured elastic scattering spectra from the nanoholes exhibit a broad resonance in the red part of the visible spectrum, which is qualitatively similar to localized surface plasmon (LSP) resonances in gold nanodisks. The hole resonance red-shifts with increasing hole diameter (D = 60−107 nm), similar to particle LSP resonances. These features could be well reproduced by electrodynamic simulations based on the boundary element method (BEM). Further, the electric field distribution around the resonant nanoholes, obtained from the BEM simulations, exhibits a clear electric dipole pattern. This confirms the assignment of the hole resonance to a dipolar LSP resonance mode. However, in comparison with Au nanodisks of similar size, the hole LSP resonance exhibits a shorter dephasing time (τ). This observation can be understood in terms of an additional decay channe.
Exits in the gasoline market: Evidence from Austria

The retail gasoline market is going through a process of restructuring and consolidation in many developed economies. During the past decade, a large number of gasoline stations have been closed down. The present paper aims to investigate this process. One of the key characteristics of the retail gasoline market is that competition is localised, and this spatial dimension of competition has to be taken into account when investigating the (binary) decision of whether or not to exit from this business. The results of a probit model estimated on the Austrian retail gasoline sector suggest that the degree of spatial differentiation (distance between gasoline stations) as well as other station-specific and regional characteristics can explain parts of the actual exit behaviour observed between 2003 and 2011.
Representation type of -Schur algebras

We give a complete classification of the classical Schur algebras and the infinitesimal Schur algebras which have tame representation type. In combination with earlier work of some of the authors on semisimplicity and finiteness, this completes the classification of representation type of all classical and infinitesimal Schur algebras in all characteristics.
Experimental study of lower-hybrid drift turbulence in a reconnecting current sheet

The role of turbulence in the process of magnetic reconnection has been the subject of a great deal of study and debate in the theoretical literature. At issue in this debate is whether turbulence is essential for fast magnetic reconnection to occur in collisionless current sheets. Some theories claim it is necessary in order to provide anomalous resistivity, while others present a laminar fast reconnection mechanism based on the Hall term in the generalized Ohm’s law. In this work, a thorough study of electrostatic potential fluctuations in the current sheet of the magnetic reconnection experiment (MRX) [Yamada et al., Phys. Plasmas 4, 1936 (1997)] was performed in order to ascertain the importance of turbulence in a laboratory reconnection experiment. Using amplified floating Langmuir probes, broadband fluctuations in the lower hybrid frequency range (fLH∼5–15 MHz) were measured which arise with the formation of the current sheet in MRX. The frequency spectrum, spatial amplitude profile, and spatial cor.
An Overview of Motion Estimation Algorithms

: With emergence of new technologies for enhancing user experience such as 3-D television results in larger amount of video data to be processed and transmitted. Video compression is likely to be an essential component of video processing for many years to come as bandwidth of today’s network is limited. It is well known that in the coding pipeline, motion estimation and motion compensation are most important and time consuming components. There is need of efficient coding and decoding with development of new range of real time applications. In this paper we have presented overview of various motion estimation algorithms.
TOXICITY OF HYDRAMETHYLNON TO BLATTA ORIENTALIS L. BY DIRECT AND INDIRECT EXPOSURE, AND EFFECTS OF HYDRAMETHYLNON BAITS AGAINST A MIXED POPULATION OF BLATTA ORIENTALIS L. AND BLATTELLA GERMANICA (L.) IN A SIMULATED DOMESTIC ENVIRONMENT

dall groups of nymphs and adults, or of 5th and 6th instar nymphs of the Oriental cockroach Blatta orientalis, were exposed to hydramethylnon baits axfo force@) for periods of time ranging from 1 to 14 days. These insects were also given access to standard laboratory cockroach food as an alternative to the hydramethylnon baits. In these tests, hydrarnethylnon baits produced high mortality (>go%) when exposure to the baits was allowed for 3 days or longer. When exposure to hydramethylnon baits was limited only to 24 iir, mortality also reached high levels, although populations containing adults appeared to be rather less affected than populations comprising 5th and 6th instar nymphs only. In tests investigating the transfer of hydramethylnon from treated cockroaches to conspecifics, 5th and 6th instar nymphs that had been exposed to hydramethylnon baits for different periods of time, were transferred to a clean glass tank containing a second, similar group of cockroaches that had not previously been exposed to the baits. After transfer, all cockroaches were fed only on standard laboratory cockroach food. In these tests, the mortality of the cockroaches directly exposed to the baits was similar to that recorded in the previous test. However, after 28 days, there was a noticeable mortality (30-50%) in the insects that had not had any previous direct exposure to hydramethylnon bait, but did have contact with cockroaches that had been exposed previously to the bait for 3-7 days. After 10 weeks, mortality in some of these indirectly-exposed cockroaches reached 100%. This transferred toxic effect was found to be transmitted by contact with (or consumption of) hydramethylnoncontarninated dead bodies, faeces and harbourages. Finally, a mixed, semi-natural infestation of B. orientalir and Blattella germanica was established in a simulated domestic environment, and exposed to hydramethylnon baits. During the first 12 weeks of this large-scale experiment, average Roatel trap counts (a standard method of population assessment) declined from a mean total of 504 insects to only 2 insects in the case of Blattella germanica, and from 208 insects to 33 insects in the case of B. orientalis.
Geomorphological aspects of gypsum karst areas with special emphasis on exposed karst

1. Mediumand large-sized forms Mediumand large-sized gypsum karst landforms are similar in many respects to those found on carbonate karst. However, there are also some differences. This chapter will review the typical landforms of gypsum karst, stressing the similarities and the differences when compared with carbonate karst forms, and discussing their morphogenetic peculiarities. In gypsum karst areas it is also commonly possible to recognise landforms produced by erosion due to surface flow and the effects of fluvial deposition, both of which are to some degree related to the presence of lenses and layers of other rock types. Landforms produced by different types of landslides are also present. Among the typical karst landforms, the following have been recognised: 1) dolines, 2) blind valleys, 3) polje-like depressions, 4) subsidence and collapse basins in rocks that overlie gypsum.
Methicillin-Resistant Staphylococcus Aureus risk perception by Healthcare Personnel in a public hospital

This study examines perceived risk of contamination by methicillin-resistant staphylococcus aureus (MRSA) among healthcare personnel in a French university hospital. MRSA poses a public health threat for healthcare staff who work in a hospital environment. This study is part of a pluridisciplinary research project on the risk factors of MRSA contamination. In many studies (Kouabenan, 1998; Slovic, 1987; Slovic et al., 1981), risk perception appears to be an important factor in understanding attitudes towards accident prevention and self-protective behavior. A questionnaire measuring several dimensions of perceived MRSA risk (risk for oneself, risk for others, severity, controllability, frequency, preventive efforts) and a questionnaire assessing optimism were administered to 187 hospital staff members of various occupations. The results revealed that the risk of MRSA contamination was well perceived as a whole by healthcare personnel. However, certain factors like proximity to patients and length of service tended to be accompanied by an underestimation of the risk, while other factors like little education, working part-time, and a lack of experience tended to cause overestimation. Preventive measures are recommended.
Analysis of the Parameters Involved in the Iris Recognition System

: Biometric recognition is a computerized identification method which is based on unique features or characteristics possessed by human beings and Iris recognition has proved itself as one of the most reliable biometric methods available owing to the accuracy provided by its unique epigenetic patterns. The main steps in any iris recognition system are image acquisition, iris segmentation, iris normalization, feature extraction and features matching. EER (Equal Error Rate) metric is considered the best metric for evaluating an iris recognition system. In this paper, different parameters viz. the sigma for blurring with Gaussian filter while detecting edges, the scaling factor to fasten the CHT (Circle Hough Transform), the gamma correction factor for gamma correction and the radius for weak edge suppression for the edge detector during segmentation; the sigma upon central frequency and the central wavelength for convolving with Log-Gabor filter during feature extraction have been thoroughly tested and analyzed on the CASIA-IrisV1 database to get an optimized parameter set. This paper provides an insight into how the parameters must be set to have an improved Iris Recognition System
The Way to the Top: Career Patterns of Fortune 100 CEOS

How have the CEOs of Fortune 100 companies worked their way to the top position? Are there several paths to the top, or have most present-day CEOs moved up the ranks in a similar fashion? We examine the employment trajectories of all of the current Fortune 100 CEOs across their entire working careers to answer these questions. The analysis developed in this article is carried out in two steps. We first use sequence analysis to find the patterns that are characteristic of the career paths of these CEOs. We then apply clustering techniques to identify distinct groups of career paths that have led individuals to the uppermost management level. Our results show that the careers of the Fortune 100 CEOs have largely followed traditional career paths that are symbolized by steady progression toward more responsibility, little mobility between firms and industries, and a strong focus on general management functions. © 2015 Wiley Periodicals, Inc.
The Use of Social Media by Prospective Teachers and Their Practice Aims of Web Technologies in Turkey

The purpose of this research is to find out prospective teachers' use of social media tools and their practice aim of web technologies. The research was prepared in survey model. Convenience sampling technique was used in the research. The sample of the research is composed of 61 prospective elementary teachers from education faculty of a state university, and 53 prospective teachers in the Department of Computer and Instructional Technology (CEIT). The data collection tool is social media and web technology usage scale which is developed by the researcher. This scale consists parts of using social media and web technologies. The first part of this scale consists of terms about social media tools and the other part consists of information about usage of web technologies. At the end of the research, it was concluded that prospective teachers always use YouTube and Instagram as readers and also other social media tools such as WhatsApp application. However, it has been found that prospective teachers tend to use Web technologies very much in their daily work, lessons and entertainment at sub-dimensions. It is advisable to carry out studies related to different science and different departments except for the prospective teachers regarding the usage of web technology.
On estimating the rank of semidefinite matrix ∗

This paper concerns the problem of rank estimation in situations where the object of interest is a semidefinite matrix using an estimator that is either indefinite or semidefinite and satisfies an asymptotic normality condition. Several rank tests are examined, based on either available approaches or basic new results. A number of related issues are discussed such as the choice of matrix estimators and rank tests based on finer assumptions than those of the asymptotic normality of matrix estimators. Several examples where rank estimation for a semidefinite matrix is of interest are studied and serve as a guide.
Abundances in planetary nebulae: Hb 5

The ISO spectra of the bilobal planetary nebula Hb 5 are presented. These spectra are combined with the spectra in the visual wavelength region to obtain a complete, extinction corrected, spectrum. The chemical composition of the nebula is then calculated in several ways. First by directly calculating and adding individual ion abundances, assuming that all the ionic lines are formed in an ionized region surrounding the ionizing star. Secondly by building an “end-to-end model” nebula in which we have included a neutral region and a photodissociation region (PDR) beyond the ionized nebula. In this way we attempt to interpret the molecular hydrogen lines observed by ISO in a more self-consistent way. In the final analysis, the model is found to be basically heuristic, but gives new insights about the PDR and the PN. The implications of these are discussed.
Trends in Bottled water Use Survey in Addis Ababa: Implication on Reverse Logistics of Bottled Water Manufacturing in Ethiopia

The trend in the changing life style of the Ethiopian people in drinking bottled water at home, work place, recreation and travel in and outside the country provided another opportunity to sale bottled water as a product in the local market and sought its potential sale in the international market as far as international water quality standards are met. However, regardless of increasing trend in the distribution logistics of bottled water to the Ethiopian domestic market and the commencement of export of plastic packaged water to international market by few branded bottled water companies raised the issue of environmental regulation as a result of the existing plastic packaged branded water products are unfriendly to the environment. In the absence of green packaging of water products for commercial use in Ethiopia, it demands for reverse logistics for recycling of plastic packages for water use. Unlike soft drink companies which voluntarily apply reverse logistics for re use of bottle for their product packaging, water bottling companies in Ethiopia are not required by law to re use/recycle plastic packages for water regardless of their negative impact on the environment as plastics take thousands of years to decompose. As a result, it is not uncommon to observe in the streets of Addis Ababa and regional towns to find plastic packages of water dumped here and there regardless of increased use by residents at home, workplace or recreation centers in daily basis. Besides, the city government of Addis Ababa organized informal sectors at micro enterprise level to play the role of collectors to remove waste from the city as their regular day to day economic activity creating significant number of employment in the city. Besides, individual households pay for removing these plastic packages for bottled water and other solid wastes from their areas to the collectors. The study explored and described the water resources management of Ethiopia focusing on trends in bottled water use by residents of Addis Ababa as unit of analysis excluding irrigation and hydropower development capabilities on water resources of Ethiopia from this study. Based on the current trend in commercializing of bottled water in national and international market, manufacturers of bottled water in Ethiopia are tapping the opportunities in the increasing consumers demand and use style for bottled water at workplace, meeting, home, and recreation and hotel services centers without due consideration of wider impact on environment of the plastic packages of water use. Therefore, the study recommends the application of reveres logistics by bottled water manufacturing companies in Ethiopia for recycling plastic packages of bottled water that should be enforced legally for environmental sustainability.
An empirical real-world study of losses disguised as wins in electronic gaming machines

Abstract Losses disguised as wins (LDWs) appear to reinforce gambling persistence. However, little research has examined this phenomenon with real gamblers in natural gambling settings. We aimed to examine the relationship between within-session outcome size and subsequent gambling persistence. Account-based gambling data of individuals playing LDW games over a randomly selected day (2,035,339 bets made by 8636 individuals) was examined. We used a logistic mixed effects model to examine the relationship between the outcome of the previous bet (loss, LDW and real wins) and the odds of continuing betting in a game session. The odds of continuing betting in a game session were positively associated with the outcome of the previous bet. Compared to LDWs, losses lowered the odds of continuing a game session. In contrast, real wins implied greater odds of continuing a game session compared to LDWs. It is concluded that LDWs increase the likelihood of continuing betting compared to losses, but decrease the likelihood of continuing to gamble compared to real wins. As LDWs increase the number of bets made within a gambling session, and hence within-session gambling persistence, LDWs may potentially play an etiological role in the development of gambling problems over time.
The Importance of Motivation in Second Language Acquisition

According to Rost (2006) motivation has been called the “neglected heart” of language teaching. As teachers, we often forget that all of our learning activities are filtered through our students’ motivation. In this sense, students control the flow of the classroom. Without student motivation, there is no pulse; there is no life in the class. When we learn to incorporate direct approaches to generating student motivation in our teaching, we will become happier and more successful teachers. The issue of motivation, particularly in EFL settings, is so important that other considerations about teaching methodology seem to pale in comparison. It is important to think about motivation as the essence of language teaching because of the stark realities of learning English for most of our students.
New observations on matildite

A study of matildite from another occurrence in the Camsell River area, N.W. T. is reported. The mineral occurs as pure irregular grains in a deposit containing native silver, native bismuth and Co-Ni arsenides and in which galena has not been identified. Single crystal studies and reflectivity measurements confirm the hexagonal symmetry postulated by Geller and Wernick, but with the a-cell dimension doubled, yielding values of a = 8.12; c = 19.02A. Electron-probe microanalysis shows that the mineral is homogeneous with a formula of Ag (sub 0.95) Bi (sub 1.00) S (sub 1.97) which agrees very well with the ideal formula AgBiS 2 . Microhardness values (25-gram load) range from VHN 59 to 76.
