The spatial structure of zooplankton communities and trophic state of mid-city Strzeszyńskie Lake

Studies on Strzeszynskie Lake were conducted in May and June 2007. The main aim of this study was to compare the composition and dynamics of the zooplankton communities between two different zones: the open water area and the littoral zone (including Chara tomentosa and Typha angustifolia stands). The stand located within Chara tomentosa possessed the highest number of identified species and most abundant zooplankton communities, while the station located within the pelagic zone was characterised by the poorest taxonomic structure and the lowest mean zooplankton densities for both rotifers and crustaceans. Zooplanktonic organisms moved in a horizontal direction in order to avoid predators. In the littoral zone, markedly high densities of pelagic species were also recorded. Furthermore, in the zone of stoneworts six Chara-associated species were found. The open water zone of Strzeszynskie Lake was dominated by limnetic species, while within macrophyte-dominated stands a more diverse dominating structure occurred, representing both limnetic and littoral species. Among dominating species the presence of species indicating low trophic conditions was recorded. The low state of the trophic conditions of the water of Lake Strzeszynskie was also confirmed by the participation of mesotrophic species in the total zooplankton abundance which reached between 14 and 72%.
STATISTICAL METHOD TO OVERCOME OVERFITTING ISSUE IN RATIONAL FUNCTION MODELS

Abstract. Rational function models (RFMs) are known as one of the most appealing models which are extensively applied in geometric correction of satellite images and map production. Overfitting is a common issue, in the case of terrain dependent RFMs, that degrades the accuracy of RFMs-derived geospatial products. This issue, resulting from the high number of RFMs’ parameters, leads to ill-posedness of the RFMs. To tackle this problem, in this study, a fast and robust statistical approach is proposed and compared to Tikhonov regularization (TR) method, as a frequently-used solution to RFMs’ overfitting. In the proposed method, a statistical test, namely, significance test is applied to search for the RFMs’ parameters that are resistant against overfitting issue. The performance of the proposed method was evaluated for two real data sets of Cartosat-1 satellite images. The obtained results demonstrate the efficiency of the proposed method in term of the achievable level of accuracy. This technique, indeed, shows an improvement of 50–80% over the TR.
Antecedentes de las consultas de boca-oído online sobre hoteles

Online reviews about goods and services prior to purchase have received less attention in the literature than comments generation after the experience. Our work addresses the study of online word-of-mouth behaviour from the receiver perspective. The aim is to investigate the variables that contribute to word-of-mouth adoption in order to make the decision to choose a hotel. The relationships chain “motivations→consult intention→volume→adoption” is analyzed, considering three types of motivations: convenience, risk and social. With a sample of 393 guests from 3, 4 and 5 star hotels and by means of a structural equations model, the results confirm these relationships, and the motivations of convenience and risk are the only ones that influence the intention to consult online word-of-mouth. Academic implications and recommendations for business management are presented to advance in this field of study.
Comparison of the Bayesian Networks using Microarray Data

Understanding gene interactions in complex living systems can be seen as the ultimate goal of the systems biology revolution. Hence, to fully understand disease ontology and to reduce the cost of drug development, gene regulatory networks (GRN) have to be constructed. During the last decade, many GRN inference algorithms like ‘Bayesian network’ that are based on genome-wide data have been developed to unravel the complexity of gene regulation. Recently, many of structure learning algorithms were used to learn Bayesian network that have shown promise in gene regulatory network reconstruction. In this paper we apply different structure learning algorithms on actual microarray data to obtain a better understanding of their relative strengths and weaknesses on the system biology community and we evaluate their outputs from different perspectives.
Effect of lipids on biomass development in anaerobic fixed-bed reactors treating a synthetic dairy waste

The aim of this work was to follow the evolution in quantity and quality of the biomass developed during the operation of two anaerobic fixed bed reactors treating a synthetic dairy waste with different lipid contents. The feasibility of a special reactor design that allowed the biomass withdrawal with minimum operation disturbances was tested. The HRT was maintained at 1.5 days and the influent concentration was gradually increased from 3 to 12 g COD/l. Initially, one reactor was loaded with skim milk and the other one with whole milk, with equal organic loading rates (OLR). The effect of lipids was evaluated in terms of reactor performance, total, adhered and entrapped biomass and evolution of biomass quality determined in batch assays by: (i) measuring of potential specific methanogenic activity against direct (acetate, H2/CO2) and indirect (propionate and butyrate) substrates; (ii) measuring of the resistance of acetoclastic bacteria to the presence of sodium oleate. The lipids reduced the adhered fraction of biomass. The methanogenic activity against butyrate was enhanced in the presence of lipids, but no significant effect was detected on the other measured activities. The biomass taken from the reactor fed with lipids was more susceptible to the presence of sodium oleate, but, over the operation period, this susceptibility was reduced.
Orbit and Dynamical Mass of the Late-T Dwarf GL 758 B

Gl 758 B is a late-T dwarf orbiting a metal-rich Sun-like star at a projected separation of ρ ≈ 1. ″6 (25 au). We present four epochs of astrometry of this system with NIRC2 at Keck Observatory spanning 2010 to 2017 together with 630 radial velocities (RVs) of the host star acquired over the past two decades from McDonald Observatory, Keck Observatory, and the Automated Planet Finder at Lick Observatory. The RVs reveal that Gl 758 is accelerating with an evolving rate that varies between 2 and 5 m s−1 yr−1, consistent with the expected influence of the imaged companion Gl 758 B. A joint fit of the RVs and astrometry yields a dynamical mass of MJup for the companion with a robust lower limit of 30.5 MJup at the 4-σ level. Gl 758 B is on an eccentric orbit (e = 0.26–0.67 at 95% confidence) with a semimajor axis of a = au and an orbital period of P = yr, which takes it within ≈9 au from its host star at periastron passage. Substellar evolutionary models generally underpredict the mass of Gl 758 B for nominal ages of 1–6 Gyr that have previously been adopted for the host star. This discrepancy can be reconciled if the system is older—which is consistent with activity indicators and recent isochrone fitting of the host star—or alternatively if the models are systematically overluminous by ≈0.1–0.2 dex. Gl 758 B is currently the lowest-mass directly imaged companion inducing a measured acceleration on its host star. In the future, bridging RVs and high-contrast imaging with the next generation of extremely large telescopes and space-based facilities will open the door to the first dynamical mass measurements of imaged exoplanets.

Implementation of High Performance Work System in Public Organizations: Implication to Organizational Performance

A principal concern among organizational researchers is to understand why some organizations irrespective of size and location outperform others. High performance work system (HPWS) offers an explanation for this phenomenon. HPWS gives organizations the competitive advantage over others. While it has been established that HPWS affect the performance of organizations within a large and complex organizations, less have been empirically established if it also create benefit for public organizations. This has generated concerns among organizational researchers. Following this argument, this study examines this theoretical gap with a survey data collected from employees in the public sector organization. Overall, three dimensions of HPWS were identified by the researchers and the level of awareness was assessed on a seven point Likert scale. We found that two out of the three identified dimensions of HPWS has a positive relationship with organizational performance.
FINLAY GREEN TEA POSSESSES THE HIGHEST IN VITRO ANTIOXIDANT ACTIVITY AMONG THE 20 COMMERCIALLY AVAILABLE TEA BRANDS OF BANGLADESH

In vitro antioxidant activities of water extract of 20 brands of tea of Bangladesh were assessed in the present investigation. Antioxidant activities were determined by estimating total antioxidant capacity (TAC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant power (FRAP) and ferrous ion chelating (FIC) ability. Finlay Green Tea had the highest polyphenol content [103.0±0.3 mg gallic acid equivalent (GAE)/g], concurrently with the highest DPPH-radical scavenging activity (IC50) (19.0±3.0 g/mL), FRAP (97.0±1.4 mg GAE/g) and TAC (325.0±0.6 mg GAE/g) but moderate FIC ability [1.22±0.09 mg disodium ethylenediaminetetracetate (EDTA)/g]. The level of antioxidant activity, without FIC ability, was strongly associated with the total phenolic content (TPC). Therefore, the teas of Bangladesh, especially the green tea (Camellia sinensis L.), may serve as a potential dietary source of natural phenolic antioxidants.
Effects of distance from cattle water developments on grassland birds

Abstract Many North American grassland bird populations appear to be declining, which may be due to changes in grazing regimes on their breeding areas. Establishment of water developments and confining cattle (Bos taurus L.) to small pastures often minimizes spatial heterogeneity of cattle forage consumption, which may lead to uniformity in vegetative structure. This increased uniformity may provide suitable habitat for some bird species but not others. We assessed how cattle use, vegetative structure, and bird population densities varied with increasing distance from water developments (0–800 m) on the Little Missouri National Grassland (LMNG) in North Dakota. Lark buntings (Calamospiza melancorys Stejneger), which are typically associated with low vegetative cover, decreased with increasing distance from water developments. Horned larks (Eremophila alpestris L.), also a low-cover associate, followed a similar but weaker trend. Densities of another low-cover associate as well as moderate- and high-cover associates were not related to distance from water. Vegetative height-density and litter depth increased by 50 and 112%, respectively, while cowpie cover and structural variability decreased by 51 and 24%, respectively, with distance from water. Confidence interval overlap was common among all measures, showing substantial variability among study sites. Our results indicate cattle use is higher closer to water developments, and this pattern may positively affect the densities of lark buntings and horned larks. The absence of density gradients in the other bird species may be due to the paucity of locations > 800 m from water on the LMNG.
Hautinfektionen durch Insektenstiche nach Fernreisen bei Kindern

Zusammenfassung Nach Fernreisen in die Tropen und Subtropen finden sich als Grund für einen Arztbesuch neben den klassischen vektorübertragenen Erkrankungen wie Malaria oder Denguefieber und der Reisediarrhö auch zu ca. 20 % neu aufgetretene dermatologische Erkrankungen. Ursächlich ist meistens der Kontakt der Haut und Schleimhäute mit Insekten durch Biss oder Stich mit einer meist juckenden Lokalreaktion und der Gefahr einer bakteriellen Superinfektion. Einige Insektenarten dienen als Vektoren für systemische Infektionen sowie lokale Hautparasitosen, andere zeigen sich als Ektoparasitosen. Die Erregerspezies von nach Fernreisen neu aufgetretenen Hautveränderungen sind vielfältig, oft ist das Spektrum der Erreger weltweit verbreitet und somit nicht speziell auf Fernreisen bezogen. Es finden sich aber auch Infektionen, die je nach Reisestil, Reisedauer, und vor allem Reiseregion in unterschiedlicher Häufung und Wahrscheinlichkeit auftreten können. Die Hautinfektionen bei Kindern unterscheiden sich nur gering von denen bei Erwachsenen. Körpergröße, Sozial- und Spielverhalten haben jedoch einen wesentlichen Einfluss auf die Häufigkeit spezieller Hautinfektionen bei Kindern nach Fernreisen. Wichtigste Form der Krankheitsvermeidung ist die Prävention eines Kontaktes mit Insekten. In diesem Artikel soll dem niedergelassenen Pädiater und Kliniker eine Kurzübersicht und Empfehlung gegeben werden, um den wichtigsten reiseassoziierten infektiologischen Hautmanifestationen bei Kindern im Alltag zu begegnen.
Relationship between Crop Diversification and Farm Income in Odisha — An Empirical Analysis

This paper has examined the extent and pattern of crop diversification and its impact on farm income across all the districts of Odisha. The determinants of crop diversification have been identified. Using the NSSO data, the study has found three districts, namely Anugul, Jharsuguda, and Balangir, to be highly diversified districts and the average farm income in these districts is significantly higher than in both moderately and least diversified districts. The medium farmers are the most diversified category of farmers in two out of the three highly diversified districts. The marginal farmers are the most diversified category of farmers in one highly diversified district. On the basis of regression analysis, the study has found that SC households in Odisha are less diversified in comparison to other households and higher the extent of irrigated land, lower is the extent of crop diversification.
THE EFFICIENCY-STABILITY TRADE-OFF: THE CASE OF HIGH INTEREST RATE SPREADS IN VENEZUELA

This paper examines the determinants of the high intermediation spread observed in the Venezuelan banking sector during the 1990s (by far the largest in the Latin American region throughout the 1990s). We trace the evolution of the spread and its connection with other bank-specific variables. A reduced-form equation is estimated on the basis of a simple behavioral model for the banking firm previously developed by Shaffer and extended by Barajas, Steiner, and Salazar. Using different types of estimators for aggregate and pooled data of the financial system, we found that high spreads can be attributed to market power, high operating costs, and expected portfolio risk. The empirical results also suggest a trade-off between assuring bank solvency and lowering profitability.
An Attack-Defense Model for the Binder on the Android Kernel Level

In this paper, we consider to seek vulnerabilities and we conduct possible attacks on the crucial and essential parts of Android OSs architecture including the framework and the Android kernel layers. As a regard, we explain the Binder component of Android OS from security point of view. Then, we demonstrate how to penetrate into the Binder and control data exchange mechanism in Android OS by proposing a kernel level attack model based on the hooking method. In addition, we provide a method to detect these kinds of attacks on Android frameworks and the kernel layer. As a result, by implementing the attack model, it is illustrated that the Android processes are detectable and the data can be extracted from any process and system calls. On the other hand, by using our detection proposed method the possibility of using this attack approach in the installed applications on the Android smartphones will be sharply decreased.

Acoustical Phonons Transport through a Stepped Quantum Wire

This work presents a theoretical approach for the study of phonon dynamics and scattering properties of an infinite linear atomic chain perturbed by a mono atomic step. The coherent transmittance scattering cross-sections for incident phonons on the atomic waveguide structure are calculated using the Landauer-Buttiker electron scattering description and the matching method formalism with the nearest and next nearest neighbour interactions. Numerical results for different configurations yield an understanding of the chain dynamical properties and the effects on phonon transmittance due to incoming phonons. The reflectance and transmittance coefficients show spectral characteristic features depending on the cut-off frequencies for the propagating phonons. They illustrate the occurrence of Fano resonances in the scattering spectra that result from degeneracy of step localized modes and propagating continuum modes due to the breakdown of the translation symmetry in the propagating direction. Furthermore, the interferences between diffused and reflected waves in the step regions generate Fabry-Perot oscillations whose number is determined by the distance between steps and the number of terraces.

Using these data, I trace the development of these spaces and determine what relationship to gentrification they may have. I then compare production-side data with consumption-side data to determine disparities amongst class in potential LGBTQ+ bar patrons in Louisville, Kentucky.
A Study of the Key Factors in Qazvin Mellat Bank customers' Effective Loyalty

A Study of the Key Factors in Qazvin Mellat Bank customers’ Effective Loyalty 1Dr Gholamreza Rahimi and 2PhD Student Mostafa akbari ABSTRACT The aim of the research is to explore contributing factors in customers’ effective loyalty in Qazvin Mellat Bank. The research is a survey research whose statistical population consisted of all customers referred to all branches of the province. The measurement instrument of the study is questionnaire and a number of 150 questionnaires were distributed in six eclectic braches in the province, of which 142 individuals completed the distributed questionnaires. In this study, data analysis was performed at two levelsdescriptive and inferential. The results indicated that all variables (flexibility, reliability, time, service, quality and price) had a positive and direct linear relationship to loyalty, i.e. increase in each of the variables could increase loyalty. However, two linear models and goodness of fit were used to make sure the stability of linearity. In the end, ratings of variables—reliability, quality, flexibility, time, price and services-are addressed using multiple regression model.
CASCADING EFFECTS OF PREDATOR REMOVAL ON THE ECOLOGY OF SEA TURTLE NESTING BEACHES

Traditional views of food web dynamics have characterized species interactions as linear and direct. However, modern food web theory suggests that interactions can also be nonlinear and indirect, so that disturbance at one trophic level is transmitted throughout the community. Many previous studies have demonstrated that the removal of top predators from terrestrial ecosystems can have broad-scale impacts on community ecology. I examined the direct and indirect effects of raccoon removal from sea turtle nesting beaches in east-central Florida during the summers of 2003 and 2004. Raccoon and ghost crab predation are among the highest causes of egg mortality for sea turtles in Florida and raccoons are intraguild predators of ghost crabs. Because of the damage done to sea turtle nests, raccoons have been removed from some beaches during the sea turtle nesting season. I compared the diet and demography of a raccoon population that had experienced two decades of raccoon removal to a population that had previously been unmanipulated. I found that long-term raccoon removal had created a significantly male-biased sex ratio in that population. I also examined the indirect effects of raccoon removal by comparing the abundances of raccoons and ghost crabs at four study sites using passive tracking plots. My data suggest intraguild predation by raccoons limits ghost crab abundance and that reduced raccoon abundance allowed ghost crab abundance to increase, resulting in a net increase in sea turtle egg predation. These results support my hypothesis that intraguild predation of ghost crabs by raccoons is an influential interaction on sea turtle nesting beach community dynamics.
