Authors: Veinbergs Arturs , Lagzdins Ainis , Jansons Viesturs , Abramenko Kaspars , Sudars Ritvars
Published: July 2017

This study is focused on water quality and quantity modelling in the Berze River basin located in the Zemgale region of Latvia. The contributing basin area of 872 km2 is furthermore divided into 15 sub-basins designated according to the characteristics of hydrological network and water sampling programme. The river basin of interest is a spatially complex system with agricultural land and forests as two predominant land use types. Complexity of the system reflects in the discharge intensity and diffuse pollution of nitrogen compounds into the water bodies of the river basin. The presence of urban area has an impact as the load from the existing wastewater treatment plants consist up to 76 % of the total nitrogen load in the Berze River basin. Representative data sets of land cover, agricultural field data base for crop distribution analysis, estimation of crop management, soil type map, digital elevation model, drainage conditions, network of water bodies and point sources were used for the modelling procedures. The semi-distributed hydro chemical model HYPE has a setup to simulate discharge and nitrogen transfer. In order to make the model more robust and appropriate for the current study the data sets previously stated were classified by unifying similar spatially located polygons. The data layers were overlaid and 53 hydrological response units (SLCs) were created. Agricultural land consists of 48 SLCs with the details of soils, drainage conditions, crop types, and land management practices. Manual calibration procedure was applied to improve the performance of discharge simulation. Simulated discharge values showed good agreement with the observed values with the Nash-Sutcliffe efficiency of 0.82 and bias of −6.6 %. Manual calibration of parameters related to nitrogen leakage simulation was applied to test the most sensitive parameters.
Environment Quality: Impact From Traffic, Power Plant and Land Morphology, a Case Study of Prishtina
Authors: Bajcinovci Bujar
Published: July 2017

Environmental air pollution is a global health concern, a complex phenomenon which is directly reflected on public health, economic and human development. Environmental air pollution has been drastically multiplied, followed by the beginning of the new Millennia in Prishtina, the capital city of the Kosovo. The new millennium began as a crucial activity for the city of Prishtina in terms of demographic, human geography, social and economic phenomena. The presented study aims to determine prevalent traffic and land morphology composition attributes, which have influenced and continue to have environmental impact in the city of Prishtina. According to the conceptual findings from the empirical observations, the heavy city traffic and the land morphology structure, determine the urban air pollution level. Prishtina is generally polluted due to its geomorphic position in relation to the power plants Kosovo A, and Kosova B. The impact of the above cited factors, is even bigger when the dominant winds prevail through valley, which encompasses the city. The findings from this paper propose the necessity of careful driven urban solutions.
A Note on Reference to Kinds in Mandarin: the N-leikindCompound
Authors: Li XuPing
Published: July 2017

This squib examines a special kind-referring expression in Mandarin Chinese, the N-leikindcompound. We show that like Mandarin bare nouns, N-leikindcompounds also denote kinds, but they can only be instantiated by sets of (sub) kind entities at type , and not sets of individuals at type . Specifically, those kind entities belong to basic-level categories in some folk taxonomy. We claim that N-lei is the nominalization counterpart of the classifier phrase lei-N, and it denotes superkinds, which are instantiated by sets of subkind entities. Accordingly, Mandarin bare nouns are comparable to bare plurals in English, whereas N-lei is comparable to definite singulars in English.
The Syntax of the Abstract-type Measurement Construction in Mandarin Chinese
Authors: Jin Jing
Published: July 2017

This paper investigates a special sub-type of measurement construction in Mandarin Chinese, namely the [Num-measure word-de-N] construction where the N is an abstract dimension-denoting noun. Evidence is presented to show that the abstract-type [Num-measure word-de-N] should be fundamentally distinguished from the quantifying-/modifying-type [Num-measure word-de-N], in which the [Num-measure word] sequence serves to quantize/modify a semantically concrete, entity-denoting N. At the interpretive level, this paper claims that the abstracttype [Num-measure word-de-N] is semantically definite. At the syntactic level, a clausal analysis within the framework of the Predicate Inversion theory is pursued to account for the derivation of the abstract-type measurement construction. Last, it is proposed that the word order distinction between the Chinese abstracttype measurement construction, which is N-final, and its English counterpart, where the N linearly precedes [Num-measure word], can be explained in terms of a parametric variation with respect to the (non-)application of N-raising after Predicate Inversion.

Since the early 1940s, a significant amount of research has been conducted to describe the impact of the high-G acceleration on the cardiovascular system. The objective of the present study was to examine the role of the antioxidant enzyme system under biodynamic stress in the liver, heart and gastric mucosa in response to high-magnitude +Gz exposure in a rat model. Twenty adult male Wistar albino rats (10 rats per group; 9-11 weeks old, 200-250 g b.w.) were divided into the following two groups: control and G (exposed to a biodynamic stress model under positive (+7 Gz) acceleration for 40 s). The influence of acute biodynamic stress on pro-oxidative parameters in the rat liver (xanthine oxidase (XOD), catalase (CAT), peroxidase (Px), glutathione peroxidase (GSH-Px), total content of glutathione (GSH), lipid peroxidation (LPx)) and on histopathological alterations in the liver, cardiac muscle and gastric mucosa was examined. Biodynamic stress resulting from positive (+7 Gz) acceleration resulted in a highly statistically signifi cant increase of CAT GSH-Px activity compared to the control group. The LPx levels were significantly decreased, but the GSH contents and the activities of other enzymes were not significantly changed. Significant microscopic changes in the liver, heart and gastric mucosa were observed in the G group. These results clearly indicate that +Gz acceleration alters biochemical systems. These alterations in cellular processes may be mediated by influences of hypoxia or ischaemia via changes in the antioxidant capacity.

Published: July 2017

There is limited knowledge on the global prescription and consumption patterns of therapeutic (TD) and illicit drugs (ID). Pooled urine analysis and wastewater-based epidemiology (WBE) has been used for local-based drug screening. It is, however, difficult to study the global epidemiology due to difficulties in obtaining samples. The aims of the study were to test the detectability of TD and ID in airplane wastewater samples categorized according to their geographical origin.

Wastewater samples (n= 17) were collected from long-distance flights and prepared with enzymatic conjugate cleaving followed by either precipitation or solid phase extraction. Aliquots were analysed on various liquid chromatography – mass spectrometers. TDs were grouped according to their Anatomical Therapeutic Chemical (ATC) codes.

Identification confidence was assigned to three levels based on variables including detection on multiple instruments and number of targets per compound. A total of 424 compounds were identified across all samples, distributed on 87 unique TD and 2 ID. Two principal components in a principal component analysis separated three clusters of wastewater samples corresponding to geographical origin of the airplanes with therapeutic subgroup ATC codes as variables. Airplane wastewater analysis is useful for identifying targets for WBE and toxicological analysis and explore drug use and abuse patterns.
Study On Budget Revenue Collection, Shadow Economy and Tax Losses Caused By It
Authors: Radu Claudia Florina , Dumiter Florin Cornel , Dudas Lavinia , Jimon Stefania Master
Published: July 2017

Tax avoidance is a phenomenon faced by all countries, to a lesser or greater extent, and we can say that it has begun to manifest itself since the introduction of taxes. It is known that generally taxes are not pleasing to taxpayers, especially when their level is high. However, it is important for individuals, as a whole, not to evade from their tax obligations. In this context taxes can be regarded as a necessary evil to ensure the resources needed for state functioning. But often some taxpayers are looking for ways to avoid taxes, engaging either in tax evasion to the shelter of the law or in fraudulent evasion. In this paper we present some of the aspects that motivate individuals to pay taxes. Also we analyze the situation of budgetary revenues in Alba County and also the evolution of the main income of consolidated general budget in Romania. In the end of the paper we intend to draw a parallel between shadow economy, tax burden and tax losses due to shadow economy for a sample of 32 countries. In this way we can see where underground economy and tax losses have the highest values and where are required measures to mitigate them.
The Geographical and Administrative Landscape of Lower Middle Egypt in Text B of the Wilbour Papyrus
Authors: Antoine Jean Christophe
Published: July 2017

The geographical information contained in text B of P. Wilbour has not been fully exploited. Completing text A, they suggest that the Memphite administration conducted the land surveys recorded in the papyrus with the consequence that the 17th and 20th Nomes of Upper Egypt (encompassing at that time the 18th, 19th, 21th and 22th Nomes) were probably administratively attached to Lower Egypt. It was also possible to propose the identification of Ope (ʾIpt) with modern Biba, P-Tjesy-Haur (PꜢ-ṯsy-Ḥur) with Saft Meidum and Onayna (ꜤꜢnꜢynꜢ) with Greek Οννη, while Su (Sw) may have been located in the vicinity of Kiman al-Arus. Furthermore, W-ḥry-ı͗b, the Middle Country, as ʾIw-ḥry-ı͗b of the contending of Horus and Seth, probably designated a part of the valley comprised between the Nile and a perennial or seasonal and probably discontinuous waterway running in the central part of the floodplain from the Herakleopolite Nome to the region of Neferusi in the 16th Nome.

Authors: Kołtuniuk Aleksandra , Rozensztrauch Anna , Beniak Marzena , Rosińczuk Joanna
Published: July 2017

Introduction. Myasthenia gravis is an autoimmune disease caused by disruption in normal neuromuscular transmission due to the reduction in the number of the acetylcholine receptors. Patients with myasthenia gravis require an individual and comprehensive nursing care to meet the needs of both biological and social nature. Properly undertaken nursing interventions improve the quality of life of patients and allow them to function independently in a daily life. An important issue is cooperation not only with the very patient, but also with their family.Case Report. A case of 57-year-old patient with myasthenia gravis, the dominant muscle weakness in both lower and upper limbs. The weakening of facial muscles and tongue, dysphagia and problems with food intake led to malnutrition and poor health condition. The onset of disease was at the age of 26, on the first day after giving birth.Discussion. Care for patients with myasthenia gravis must be comprehensive, and nursing-therapeutic care should meet individual patient’s needs in accordance with applicable guidelines.Conclusions. The case of the patient with myasthenia gravis allowed to identify the difficulties she struggled with. The main activities of nursing care provided the patient with the feeling of safety, better psychomotor activity and assistance in self-care activities. The knowledge about disease and its complications helped to improve daily functioning and coping with difficult situations. All measures taken in this regard proved to be effective, as they reduced anxiety and weakened the sense of isolation and loneliness. (JNNN 2017;6(2):88–97)

Deep brain stimulation of the subthalamic nucleus (STN-DBS) can improve the motor symptoms of Parkinson’s disease (PD) and negate the problematic side effects of dopamine replacement therapy. Although there is concern that STN-DBS may enhance the development of gambling disorder and other impulse control disorders in this patient group, recent data suggest that STN-DBS may actually reduce iatrogenic impulse control disorders, and alleviate obsessive-compulsive disorder (OCD). Here, we sought to determine whether STN-DBS was beneficial or detrimental to performance of the rat gambling task (rGT), a rodent analogue of the Iowa Gambling Task (IGT) used to assess risky decision making clinically. Rats chose between four options associated with different amounts and probabilities of sugar pellet rewards versus timeout punishments. As in the IGT, the optimal approach was to favor options associated with smaller per-trial gains but lower timeout penalties. Once a stable behavioral baseline was established, electrodes were implanted bilaterally into the STN, and the effects of STN-DBS assessed on-task over 10 consecutive sessions using an A-B-A design. STN-DBS did not affect choice in optimal decision makers that correctly favored options associated with smaller per-trial gains but also lower penalties. However, a minority (∼25%) preferred the maladaptive “high-risk, high-reward” options at baseline. STN-DBS significantly and progressively improved choice in these risk-preferring rats. These data support the hypothesis that STN-DBS may be beneficial in ameliorating maladaptive decision making associated with compulsive and addiction disorders.
Amyloid precursor protein in pancreatic islets
Authors: Kulas Joshua A , Puig Kendra L , Combs Colin K
Published: July 2017

The amyloid precursor protein (APP) has been extensively investigated for its role in the production of amyloid beta (Aβ), a plaque-forming peptide in Alzheimer’s disease (AD). Epidemiological evidence suggests type 2 diabetes is a risk factor for AD. The pancreas is an essential regulator of blood glucose levels through the secretion of the hormones insulin and glucagon. Pancreatic dysfunction is a well-characterized consequence of type 1 and type 2 diabetes. In this study, we have examined the expression and processing of pancreatic APP to test the hypothesis that APP may play a role in pancreatic function and the pathophysiology of diabetes. Our data demonstrate the presence of APP within the pancreas, including pancreatic islets in both mouse and human samples. Additionally, we report that the APP/PS1 mouse model of AD overexpresses APP within pancreatic islets, although this did not result in detectable levels of Aβ. We compared whole pancreas and islet culture lysates by Western blot from C57BL/6 (WT), APP−/−and APP/PS1 mice and observed APP-dependent differences in the total protein levels of GLUT4, IDE and BACE2. Immunohistochemistry for BACE2 detected high levels in pancreatic α cells. Additionally, both mouse and human islets processed APP to release sAPP into cell culture media. Moreover, sAPP stimulated insulin but not glucagon secretion from islet cultures. We conclude that APP and its metabolites are capable of influencing the basic physiology of the pancreas, possibly through the release of sAPP acting in an autocrine or paracrine manner.

En este artículo se indagan y comparan las teorías de Jacques Rancière y Nelly Richard sobre la relación entre arte y política desde el pensamiento  posfundacional, y se producen reflexiones y análisis de manifestaciones artísticas latinoamericanas vanguardistas o críticas en diálogo con ambas. Para ello, se parte de una presentación de las teorías de Rancière y Richard  en términos generales, se focaliza en las ideas que dichos autores tienen de la política y, específicamente, en la conceptualización que hacen del arte y su relación con la política. Al mismo tiempo, se desarrolla una interpretación de producciones artísticas desde una mirada centrada en sus diversas conexiones con lo político, más allá del contenido temático de estas. Se utiliza la perspectiva metodológica cualitativa transdisciplinaria, que articula distintas
áreas de conocimiento (filosofía política, sociología, historia del arte). En el caso de los desarrollos de Jacques Rancière, se recurre a herramientas teóricas metropolitanas para resituarlas y repensarlas en función del arte de Latinoamérica. En este sentido, se trata de potenciar sus ideas en el análisis de casos locales. En cuanto a la teoría de Nelly Richard, sus conceptos de arte crítico y vanguardista se ponen en relación con el arte latinoamericano. Finalmente, se propone una comparación en la cual se destacan similitudes y diferencias conceptuales entre ambos en combinación con análisis de casos para abrir el panorama analítico e interpretativo que vincule teorías actuales con estudios de manifestaciones artísticas locales.
Two Types of Etiological Mutation in the Limb-Specific Enhancer ofShh
Authors: Amano Takanori , Sagai Tomoko , Seki Ryohei , Shiroishi Toshihiko
Published: July 2017

An enhancer named MFCS1 regulates Sonic hedgehog (Shh) expression in the posterior mesenchyme of limb buds. Several mutations in MFCS1 induce ectopic Shh expression in the anterior limb bud, and these result in preaxial polydactyly (PPD). However, the molecular basis of ectopic Shh expression remains elusive, although some mutations are known to disrupt the negative regulation of Shh expression in the anterior limb bud. Here, we analyzed the molecular mechanism of ectopic Shh expression in PPD including in a mouse mutation—hemimelic extra toes (Hx)—and in other MFCS1 mutations in different species. First, we generated transgenic mouse lines with a LacZ reporter cassette flanked with tandem repeats of 40 bp MFCS1 fragments harboring a mutation. The transgenic mouse line with the Hx-type fragment showed reporter expression exclusively in the anterior, but not in the posterior margins of limb buds. In contrast, no specific LacZ expression was observed in lines carrying the MFCS1 fragment with other mutations. Yeast one-hybrid assays revealed that the msh-like homeodomain protein, MSX1, bound specifically to the Hx sequence of MFCS1. Thus, PPD caused by mutations in MFCS1 has two major types of molecular etiology: loss of a cis-motif for negative regulation of Shh, and acquisition of a new cis-motif binding to a preexisting transcription factor, as represented by the Hx mutation.

América Latina en tiempos de restauración neoliberal: ?qué hacemos ahora?
Authors: Mora-Ramírez Andrés
Published: July 2017

Este ensayo ofrece una perspectiva de interpretación de la coyuntura política latinoamericana de los últimos dos a tres años caracterizada por un lado, por lo que algunos analistas llaman fin del ciclo progresista y nacional-popular; y por el otro, por el ascenso electoral de gobiernos y partidos de derecha, que impulsan una restauración del proyecto neoliberal en la región. Se presenta una contextualización de este doble proceso y de sus principales dimensiones de conflicto, y se reflexiona, desde una posición de identificación y acompañamiento crítico con el proyecto progresista y nacional-popular latinoamericano, sobre  la necesidad de que los movimientos sociales, partidos políticos e intelectuales orgánicos de las izquierdas latinoamericanas asuman como tarea la disputa por la hegemonía política y cultural frente al proyecto de actualización del neoliberalismo.

Authors: Zapata Zapata Arley David , Hours Roque Alberto , Cavalitto Sebastian Fernando
Published: July 2017

Protopectinasa-SE (PPasa-SE) es una poligalacturonasa producida por Geotrichumklebahnii con capacidad de liberar pectina por hidrólisis de protopectina. La reacción de liberación de pectina responde a un sistema de catálisis heterogenea, donde la interacción enzima-protopectina y la liberación de pectina, son objetivos de esta investigación. La interacción enzima-protopectina resultó dependiente del tamaño y estructura de las partículas del sustrato, así como de la naturaleza de la solución amortiguadora. Para partículas pequeñas la cinética de adsorción siguió un comportamiento definido por la isoterma de Langmuir. La reacción respondió al modelo cinético de Michaelis-Menten, con valores de Km y Vmax de 30.2 g/L y 57.3 g/L.h. Los mejores resultados en cuanto a la adsorción de la enzima y la solubilización de pectina fueron obtenidos con una solución amortiguadora de citrato y citrato-fosfato. Este trabajo constituye un primer reporte en cuanto a la solubilización de pectina que involucra un modelo de unión al sustrato asociado en sistemas pectinasa-protopectinasa.

Estados físicos da matéria. Simulações computacionais no 5º ano de escolaridade
Authors: Araújo Fatima Maria , Lopes Bernardino , Cravino José , Soares Armando

As mudanças do estado físico da matéria poderão ser melhor compreendidas pelos alunos do 5.º ano de escolaridade se os alunos adquirirem noções básicas da teoria corpuscular e cinético-molecular. A introdução precoce do conceito de partícula, da sua dinâmica e da interação entre partículas também poderá reduzir o aparecimento de conceções alternativas e facilitar a compreensão futura dessas teorias. Apesar de serem conceitos abstratos e de difícil compreensão, tanto pela natureza das partículas como pela sua dimensão, a utilização de simulações computacionais poderão reduzir a abstração necessária à compreensão de tais conceitos. O objetivo deste estudo foi avaliar a eficácia de diferentes estratégias de utilização de simulações computacionais, na aprendizagem das mudanças do estado físico da matéria a nível microscópico, em alunos com idades entre os 9 e os 11 anos. O estudo foi realizado em quatro turmas. Foram utilizadas duas simulações e quatro formas de as integrar no currículo. Recolheram-se dados sobre o ensino e da aprendizagem recorrendo em particular à realização de um pré-teste e de um pós-teste. O estudo permitiu verificar qual das estratégias de integração das simulações computacionais no currículo foi mais eficaz.

O que leva alguém a cursar uma pós-graduação? Com o objetivo de explorar e descrever variáveis motivacionais associadas à busca e permanência do ensino nesse nível, realizou-se uma pesquisa quantitativa, on-line, com 78 participantes (67,9% mulheres; 93,6% do Sudeste), mestrandos e doutorandos, em 2015. A partir de um instrumento criado para tal finalidade e psicometricamente adequado (χ2(62) = 74,873, p = 0,126; CFI = 0,96, TLI = 0,95, RMSEA = 0,05), concluiu-se que aspectos voltados à empregabilidade (por exemplo, diferenciação e remuneração) foram preponderantes nos resultados. Esses achados apontam para uma modificação no perfil acadêmico, ainda pouco associado ao retorno financeiro. Como se sabe que a educação faz parte de investigações que atravessam aspectos administrativos, econômicos e sociais, este trabalho permite ações em diversas áreas.

Published: July 2017

ABSTRACT: Zeolites are minerals that have intriguing properties such as water absorption, ion adsorption and cation exchange capacity. There are approximately 80 species of natural zeolites recognized and hundreds of artificial zeolites, which have been researched in several fields. Due to their chemical characteristics, zeolites have great potential for use in animal production, especially in poultry and swine farms, as food additives, litter amendment and treatment of residues, with direct and indirect effects on performance, yield and quality of carcass, ambience of farm sheds and reduction of environmental pollution.

ABSTRACT: Seventeen outbreaks of dermatophilosis are reported from three farms affecting Santa Inês and Santa Inês x Dorper sheep that were reared in irrigated areas with rotational grazing at a stocking rate of 50 to 100 sheep per hectare, in the Brazilian semiarid region. Most outbreaks occurred after rains and affected sheep of different ages, with morbidity rates of 0.77% to 31%. Clinical signs were dermatitis with crusts that stood out easily and left areas of alopecia. Dermatophilus congolensis was isolated in cultures in 5% sheep blood agar by means of Haalstra’s method. Histologically, the epidermis showed extensive multifocal areas of ortho and parakeratotic hyperkeratosis with intracorneal microabscesses and presence of D. congolensis. Sheep affected were isolated from the flocks and they recovered after treatment with 70,000IU of procaine penicillin G and 70mg of dihydrostreptomycin sulphate per kg of bodyweight. Dermatophilosis is a frequent endemic disease in rotational grazing systems with irrigated pastures and high stocking rates, which occurs with higher frequency after rains and can be controlled efficiently through isolation of the affected sheep, followed by application of a single dose of penicillin and streptomycin.
Predicting financial distress in publicly-traded companies

ABSTRACT Several models for forecasting bankruptcy have been developed over the years, one of the reasons for which is the important part it plays in decision-making. However, forecasting a company’s bankruptcy leaves a very short time for stakeholders to change the situation. It is in this context that this paper arises in order to develop a model for predicting financial distress, which is identified as a step prior to bankruptcy. The predictive model uses the logistic regression technique with panel data and a sample of Brazilian publicly-traded companies with shares listed on the São Paulo Stock, Commodities, and Futures Exchange between 2001 and 2014. As well as financial variables, the final model includes market expectations (macroeconomic) and sector variables. These variables are statistically tested and the hypothesis is confirmed that they improve the accuracy of the model. The research identified the existence of financial distress in 96% of the companies that went bankrupt. In addition, the relationship between the phenomena of bankruptcy and financial distress is verified, using financial and macroeconomic explanatory variables. The results demonstrate that most (83%) of the explanatory variables in the model for predicting bankruptcy are also present in the model for predicting the phenomenon of financial distress. The expected gross domestic product variables and the quick ratio, asset turnover, and net equity over total liabilities financial variables are statistically significant in predicting both phenomena. With this evidence, the study suggests the use of the concept of financial distress as a stage prior to bankruptcy and provides a model for predicting financial distress with 89% accuracy when applied to publicly-traded companies in Brazil in the period examined.

RESUMO Objetivo Compreender a percepção de usuários de um Centro de Atenção Psicossocial sobre o cuidado no contexto do consumo de drogas. Métodos Estudo fundamentado na Fenomenologia de Maurice Merleau-Ponty, desenvolvido no segundo semestre do ano de 2015. Foram realizados dois encontros de Grupo Focal, com dez usuários de um Centro de Atenção Psicossocial Álcool e outras Drogas. Os dados foram submetidos à técnica Analítica da Ambiguidade. Resultados O consumo de drogas ora proporciona ao consumidor sensações de prazer, ora contribui para a ocorrência de prejuízos biopsicossociais e/ou novas possibilidades de relação com a droga. Conclusões O consumo de drogas constitui-se em um processo ambíguo, que corresponde à percepção de diferentes perfis de cuidado na relação do consumidor com a droga. Cabe aos profissionais de saúde reconhecer as diversas possibilidades de cuidado e favorecer a construção de projetos terapêuticos baseados na escuta e respeito às necessidades dos consumidores de drogas.
