O Uso de Famílias de Circuitos e Rede Neural Artificial para Previsão de Demanda de Energia Elétrica
Authors: Todesco José Leomar , Pimentel Francisco J. S. , Bettiol Arlan L.
Published: July 2016

A busca pela melhoria na qualidade da distribuição é uma constante nas empresas de energia. As metodologias atuais de supervisão das redes de distribuição utilizando geoprocessamento baseiam-se no cálculo de demanda dos transformadores através do uso de uma única curva de correlação kWh x kVA que emprega técnicas estatísticas. Este método édenominado método indireto de previsão da carga, e dele decorrem todos os cálculos elétricos do circuito para aferir seu desempenho quanto à qualidade dos níveis de tensão, do carregamento dos equipamentos e condutores, do balanceamento da carga, bem como das perdas elétricas. Este artigo apresenta uma proposta de estudo das famílias de circuitos (residencial, comercial, industrial, rural, público e outros) utilizando informações sobre o consumo de energia através da aplicação de algoritmos de clustering e, posteriormente, da aplicação de uma Rede Neural Artificial (RNA) para a aproximação das curvas de demanda para as famílias identificadas. A RNA utilizada foi a Radial Basis Function (RBF), por ser um aproximador universal. São também apresentados no artigo testes comparativos realizados com o modelo de regressão linear simples e a RBF.
Becoming a Modern Public Research University: The Postwar Challenges of Rutgers and Penn State, 1945-1965
Authors: Geiger Roger L.
Published: July 2016

Both Rutgers and Penn State Universities developed into modern research universities in the two decades after World War II. This paper describes how both overcame uncertain relations with their respective states and relatively weak financial support. Both evolved a significant share of the public provision of higher education. And both also strived to establish a reputation for quality undergraduate education. For research, it was necessary to obtain the resources to compete for grants in the federal research economy. Continuation of the advances made in these decades have allowed both institutions to solidify their standings among the top 40 American research universities.
Cabin in the Pines: Albert Music Hall and Constructions of a Pine Barrens Musical Tradition
Authors: Lutz Christine A.
Published: July 2016

Albert Music Hall is an outpost of bluegrass, folk, and country music in the New Jersey Pine Barrens, offering hours of live music every Saturday night. It has formally been in existence since the 1970s under the auspices of the Pinelands Cultural Society, but it traces its roots back to the 1950s, when brothers Joe and George Albert started hosting informal musical gatherings at their Pines fox hunting cabin, known in the area as the Homeplace. What started as locals playing old-time and country music at a rustic cabin deep in the woods has evolved into a more formal venue that features musicians from around New Jersey and beyond. Albert Music Hall has persisted as an island of an older, more rural, and isolated Pines in an industrialized, urbanized state. Through an examination of the language, material culture, and music of the venue, this paper considers questions and constructions of authenticity in relation to notions of what a true Pine Barrens musical experience might be for Albert Music Hall audiences and musicians.
From Riot to Revolt: Asbury Park in July 1970
Authors: Weeks Daniel
Published: July 2016

This paper investigates the civil unrest that rocked the New Jersey resort city of Asbury Park for four days in July 1970. It focuses particularly on how various participants and the media represented the violent events in the West Side of the city. These representations, which were publicized in the Asbury Park Press, the New York Times, and elsewhere, demonstrate two interrelated dynamics. First, that in attempting to characterize the events in Asbury Park as either as a criminal riot or justifiable revolt participants on all sides resorted to well-worn stereotypes, and second, that these stereotypes, once publicized in the media, began to shape events in the city in consequential ways. This study also demonstrates that the civil unrest moved through several phases from a teenage "rock and bottle festival" to a true revolt against discrimination, segregation, and the general conditions of the ghetto.

Legislative Term Limits and Government Spending: Theory and Evidence from the United States
Authors: Asako Yasushi , Matsubayashi Tetsuya , Ueda Michiko
Published: July 2016

What are the fiscal consequences of legislative term limits? To answer this question, we first develop a legislative bargaining model that describes negotiations over the allocation of distributive projects among legislators with different levels of seniority. Building on several predictions from the model, we develop two hypotheses for empirical testing. First, the adoption of term limits that results in a larger reduction in the variance of seniority within a legislature increases the amount of government spending. Second, legislatures that adopt stricter term limits increase the amount of government spending, while legislatures that adopt moderate term limits show no change in the amount. We provide evidence for these hypotheses using panel data for 49 US state legislatures between 1980 and 2010.
A multipurpose modular drone with adjustable
arms produced via the FDM additive
manufacturing process
Authors: Brischetto Salvatore , Ciano Alessandro , Ferro Carlo Giovanni
Published: July 2016

The present paper shows an innovative multirotor
Unmanned Aerial Vehicle (UAV) which is able to easily
and quickly change its configuration. In order to satisfy
this feature, the principal structure is made of an universal
plate, combined with a circular ring, to create a rail
guide able to host the arms, in a variable number from 3
to 8, and the legs. The arms are adjustable and contain all
the avionic and motor drivers to connect the main structure
with each electric motor. The unique arm design, defined
as all-in-one, allows classical single rotor configurations,
double rotor configurations and amphibious configurations
including inflatable elements positioned at the
bottom of the arms. The proposed multi-rotor system is
inexpensive because of the few universal pieces needed
to compose the platform which allows the creation of a
kit. This modular kit allows to have a modular drone with
different configurations. Such configurations are distinguished
among them for the number of arms, number of
legs, number of rotors and motors, and landing capability.
Another innovation feature is the introduction of the 3D
printing technology to produce all the structural elements.
In this manner, all the pieces are designed to be produced
via the Fused Deposition Modelling (FDM) technology using
desktop 3D printers. Therefore, an universal, dynamic
and economic multi-rotor UAV has been developed.

Published: July 2016

In the last 10 years the sunflower crop area of Argentina has shifted towards the Southwest as a result of the expansion of soybean cultivation. Early sowings require greater tolerance to low temperatures in order to optimize the use of water resources by the crop, especially in the seedling stage, when cold stress limits growth and productivity.Helianthus petiolarisis a wild genetic resource that has contributed to the production of sunflower cultivars. The goal of this study was to evaluate the tolerance to low temperatures inH. petiolarisplants. Morphological traits (plant height, leaf width and leaf length) and physiological traits (electrolyte leakage, chlorophyll content, and glucose content) were compared in eight accessions having an early germination in the field and one with normal life cycle. Acclimated and non-acclimated plants were subjected to cold stress followed by a recovery period. Physiological traits during early growth stages showed differences in cold tolerance and for acclimation ability between accessions, suggesting the existence of heritable components. Four accessions were the most cold-tolerant among the studied populations, suggesting a natural adaptation related to the geographical site. Results point out thatH. petiolarisis a useful genetic resource to contribute to sunflower breeding in the search of cold tolerant cultivars.
Triathlon wetsuit removal strategy: physiological cost of running with a wetsuit
Authors: Ciulei Mihaela , Prado Aaron , Navalta James , Mercer John A.
Published: July 2016

Triathletes exiting the swim portion of an event have to decide on how and when to take a wetsuit off (if worn). The purpose of this study was to determine the physiological cost of running while not using a wetsuit, carrying a wetsuit, wearing a wetsuit halfway down or wearing a wetsuit fully up. Participants (n = 20, 30.9 ± 8.7 yrs, 1.71 ± 0.08 m, 71.6 ± 9.5 kg) completed four 5 min running conditions: 1) not wearing the wetsuit, 2) wearing the wetsuit fully up, 3) wearing the wetsuit halfway down, and 4) carrying the wetsuit. A rate of oxygen uptake, a heart rate, ratings of perceived exertion and stride frequency were measured and were each influenced by wetsuit condition (p < 0.05). Each variable (i.e., a rate of oxygen uptake, a heart rate, stride frequency) was lower during running while not wearing the wetsuit vs. any other condition (p < 0.05). The rate of oxygen uptake was greatest during wearing the wetsuit halfway down vs. any other condition (p < 0.05). The heart rate was not different between any of the combinations of either wearing the wetsuit fully up or halfway down or carrying the wetsuit (p > 0.05). The rating of perceived exertion was greater during wearing the wetsuit halfway down vs. carrying the wetsuit (p < 0.05). Stride frequency was lower during not wearing the wetsuit vs. wearing the wetsuit halfway down or fully up (p < 0.05). It was concluded that running with the wetsuit halfway down resulted in the greatest rate of oxygen uptake, heart rate and rating of perceived exertion.

Authors: Bernacka Ryszarda Ewa , Sawicki Bogusław , Mazurek-Kusiak Anna , Hawlena Joanna
Published: July 2016

The main objective of this study was to investigate whether the personality dimension of conformism/nonconformism was a predictor of stress coping styles in athletes training combat sports, and to present the characteristics of this personality dimension in the context of the competitors’ adaptive/innovative sport performance. Scores of 346 males practising combat sports such as kick boxing, MMA, thai boxing, boxing and wrestling were analyzed. The participants completed the Creative Behaviour Questionnaire (KANH III) measuring the conformity/nonconformity personality dimension and the Coping Inventory for Stressful Situations (CISS) measuring stress coping styles. The comparative analyses were conducted only for the groups of conformists and nonconformists. Differences in stress coping styles between conformists and nonconformists training combat sports were found as nonconformists tended to prefer the task-oriented coping style. Conclusively, a higher rate of nonconformity was associated with increasingly frequent occurrence of task-oriented coping and decreasingly frequent emotion-oriented coping.

Published: July 2016

This study analyzed soccer players’ retention of coaches’ feedback during training sessions. We intended to determine if the retention of information was influenced by the athletes’ personal characteristic (age, gender and the sports level), the quantity of information included in coach’s feedback (the number of ideas and redundancy), athletes’ perception of the relevance of the feedback information and athletes’ motivation as well as the attention level. The study that was conducted over the course of 18 sessions of soccer practice, involved 12 coaches (8 males, 4 females) and 342 athletes (246 males, 96 females), aged between 10 and 18 years old. All coach and athlete interventions were transposed to a written protocol and submitted to content analysis. Descriptive statistics and multiple linear regression were calculated. The results showed that a substantial part of the information was not retained by the athletes; in 65.5% of cases, athletes experienced difficulty in completely reproducing the ideas of the coaches and, on average, the value of feedback retention was 57.0%. Six variables with a statistically significant value were found: gender, the athletes’ sports level, redundancy, the number of transmitted ideas, athletes’ perception of the relevance of the feedback information and the athletes’ motivation level.
Guava Osmotic Dehydration: Description by Two-Dimensional Diffusion Models Considering Shrinkage and Variations in Process Parameters
Authors: de Farias Aires Juarez Everton , da Silva Wilton Pereira , Cavalcante de Almeida Farias Aires Kalina Lígia , Júnior Aluízio Freire da Silva , de Castro Deise Souza , Silva Cleide Maria Diniz Pereira da Silva e
Published: July 2016

This article describes the osmotic dehydration of guava dipped in sucrose solutions using two-dimensional numerical solutions of the diffusion equation with boundary condition of the first kind. Two models are used: model 1 disregards the shrinkage of the product and assumes that effective mass diffusivity does not vary during the process; model 2 takes into account shrinkage, considering effective mass diffusivity as variable. Process parameters estimation is obtained by means of an optimizer. Comparative analyzes indicate that the proposed models have similar statistical indicators. However, model 2 is recommended, for it presents much higher physical fitness when describing mass migrations. Comparison between two-dimensional numerical models presented in this research and one-dimensional models found in the literature reveals that one-dimensional models overestimate process parameters. In addition, one-dimensional models present limitations in predicting the distributions of water and sucrose on guava slices.
Multi-granularity Bandwidth Allocation for Large-Scale WDM/TDM PON
Authors: Gao Ziyue , Gan Chaoqin , Ni Cuiping , Shi Qiongling
Published: July 2016

WDM (wavelength-division multiplexing)/TDM (time-division multiplexing) PON (passive optical network) is being viewed as a promising solution for delivering multiple services and applications, such as high-definition video, video conference and data traffic. Considering the real-time transmission, QoS (quality of services) requirements and differentiated services model, a multi-granularity dynamic bandwidth allocation (DBA) in both domains of wavelengths and time for large-scale hybrid WDM/TDM PON is proposed in this paper. The proposed scheme achieves load balance by using the bandwidth prediction. Based on the bandwidth prediction, the wavelength assignment can be realized fairly and effectively to satisfy the different demands of various classes. Specially, the allocation of residual bandwidth further augments the DBA and makes full use of bandwidth resources in the network. To further improve the network performance, two schemes named extending the cycle of one free wavelength (ECoFW) and large bandwidth shrinkage (LBS) are proposed, which can prevent transmission from interruption when the user employs more than one wavelength. The simulation results show the effectiveness of the proposed scheme.

Published: July 2016

Intersymbol interference and attenuation of signal are two major parameters affecting the quality of transmission in Free Space Optical (FSO) Communication link. In this paper, the impact of these parameters on FSO communication link is analysed for delivering high-quality data transmission. The performance of the link is investigated under the influence of amplifier in the link. The performance parameters of the link like minimum bit error rate, received signal power and Quality factor are examined by employing erbium-doped fibre amplifier in the link. The effects of amplifier are visualized with the amount of received power. Further, the link is simulated for moderate weather conditions at various attenuation levels on transmitted signal. Finally, the designed link is analysed in adverse weather conditions by using high-power laser source for optimum performance.

Published: July 2016

BACKGROUND:

A sequential approach to young febrile infants on the basis of clinical and laboratory parameters, including procalcitonin, was recently described as an accurate tool in identifying patients at risk for invasive bacterial infection (IBI). Our aim was to prospectively validate the Step-by-Step approach and compare it with the Rochester criteria and the Lab-score.

METHODS:

Prospective study including infants ≤90 days with fever without source presenting in 11 European pediatric emergency departments between September 2012 and August 2014. The accuracy of the Step-by-Step approach, the Rochester criteria, and the Lab-score in identifying patients at low risk of IBI (isolation of a bacterial pathogen in a blood or cerebrospinal fluid culture) was compared.

RESULTS:

Eighty-seven of 2185 infants (4.0%) were diagnosed with an IBI. The prevalence of IBI was significantly higher in infants classified as high risk or intermediate risk according to the Step by Step than in low risk patients. Sensitivity and negative predictive value for ruling out an IBI were 92.0% and 99.3% for the Step by Step, 81.6% and 98.3% for the Rochester criteria, and 59.8% and 98.1% for the Lab-score. Seven infants with an IBI were misclassified by the Step by Step, 16 by Rochester criteria, and 35 by the Lab-score.

CONCLUSIONS:

We validated the Step by Step as a valuable tool for the management of infants with fever without source in the emergency department and confirmed its superior accuracy in identifying patients at low risk of IBI, compared with the Rochester criteria and the Lab-score.

Published: July 2016

En países con climas tropicales, como Brasil, las altas temperaturas asociadas con altas humedades relativas en el verano contribuyen como un factor de estrés en la producción animal. El calor excesivo dentro de una instalación avícola causa una reducción en el consumo de alimento y en la producción, y aumento en la mortalidad de las aves. Conociendo que el 75% de la carga de calor radiante dentro de una instalación viene desde el techo, es necesario estudiar alternativas que pueden minimizar esta radiación. El objetivo del presente trabajo fue analizar el ambiente térmico dentro de los modelos físicos de instalaciones de pollos de engorde construidos a escala reducida (1:10), donde el confort térmico se evaluó por el índice de humedad y de globo negro (BGHI) y la carga de calor radiante (RHL). Cinco modelos construidos fueron evaluados con diferentes materiales para techos. Basados en los resultados, se puede concluir que los techos construidos con tejas de cerámica (TB30), placas de fibra natural pintadas de blanco con en el lado externo (TFVP15) y placas de fabricadas con envases larga vida reciclado (TLV15), proporcionan los mejores ambientes térmicos.
Diferencias entre el uso de sulfato férrico y cloruro férrico en la biodesulfurización de un carbón con tamaño de partícula grueso

Published: July 2016

Se evaluaron tres fuentes de hierro (FeSO4, Fe2(SO4)3 y FeCl3) a diferentes concentraciones (150, 700 y 1250 mg Fe/L) en procesos de biodesulfurización de un carbón con tamaño de partícula grueso, utilizando un consorcio de Acidithiobacillus ferrooxidans (ATCC 23270) and Acidithiobacillus thiooxidans (ATCC 15494). Al usar 150 mg Fe2+/L (FeSO4), luego de 12 días se obtuvo 31.14% de pirita oxidada. Al reemplazar FeSO4 por Fe2(SO4)3, la oxidación mejoró en un 21.16%. Aunque los ensayos con las mayores concentraciones de sulfatos obtuvieron un resultado similar, al utilizar Fe2(SO4)3 permitió mejor remoción de sulfatos del carbón. Lo anterior sugiere que basta con utilizar la menor concentración de Fe2(SO4)3 para mejorar el índice de oxidación de pirita y evitar formación de precipitados. Por otra parte, los ensayos con FeCl3 tuvieron una disminución en la tasa de biooxidación, indicando a priori, que los microorganismos no fueron capaces de adaptarse adecuadamente a los iones Cl-.

Published: July 2016

Se fabricaron recubrimientos barrera térmica depositando polvos de CoNiCrAlY y YSZ, los cuales constituyeron las capas de enlace y superior, respectivamente. La primera se depositó sobre el acero inoxidable AISI 304 mediante un sistema de oxígeno combustible de alta velocidad; mientras que la segunda se depositó mediante un sistema de rociado por plasma atmosférico. Los recubrimientos se trataron térmicamente a 1200 °C por 8 y 16 h con el fin de determinar la evolución del estado de esfuerzos residuales en función del tiempo. Los perfiles de esfuerzos residuales se determinaron empleando el método de remoción de capa modificada y una adaptación de éste para recubrimientos bicapa, llamado método de remoción de capa modificada para recubrimientos dúplex. Se encontró que conforme el tiempo de exposición se incrementó los esfuerzos residuales de compresión incrementaron, siendo más notorios en las capas de enlace. Los recubrimiento sin tratamiento térmico revelaron esfuerzos residuales de tensión.

El objetivo general de este trabajo fue encontrar un nuevo valor agregado a las hojas de las agaváceas, desecho de la agroindustria. Se estudiaron cuatro especies de agaves de tres estados de la república mexicana: Agave angustifolia (Oacaxa), Agave tequilana (Jalisco), Agave salmiana y Agave lechuguilla (Hidalgo). Luego de una clasificación taxonómica, fenológica, ecológica y etnobotánica (basados en morfología comparada), se sometieron a diversos análisis físicos (humedad, molienda, tamizaje, granulometría y características foliares, MEB) y químicos (cenizas grasas y aceites, proteínas, análisis TGA y DTGA, así como FTIR). Las especies de A. angustifolia y A. tequilana son las que presentan un óptimo tamaño de fibra para la elaboración de papel. Corresponde también a los mayores porcentajes de celulosa (44.3% y 36.8%) por DTGA. Del análisis proximal, se evidencia que las dos especies definidas como mejores para la obtención de pulpa de celulosa, presentan pequeñas diferencias significativas en contenidos de grasas, proteínas, material solubilizable en agua caliente (AT) como en solución moderadamente alcalina y/o alcohólica.

La actividad de las matronas de la Beneficencia Municipal en Cuenca (España) a comienzos del siglo XX desde la perspectiva de género
Authors: González García Alberto
Published: July 2016

Las matronas constituyen un ejemplo de mujeres en las profesiones sanitarias que lucharon por su visibilidad en un universo biomédico androcéntrico que tendió a ignorarlas u ocultarlas. Por ello, el objetivo general de este artículo es analizar el proceso de incorporación de las matronas a las instituciones de Beneficencia Municipal de Cuenca (España) para poner de manifiesto cómo estuvieron relegadas a un segundo plano. La metodología incluye el análisis del proceso desde el punto de vista de las relaciones de género. Se ha consultado el Archivo Municipal de Cuenca, el Archivo Histórico Provincial y se han analizado los principales periódicos locales de la época. Los datos epidemiológicos provienen del Instituto Nacional de Estadística. Mientras que los médicos y los practicantes contaron con un ámbito profesional específico dentro del ayuntamiento, las matronas no lo consiguieron hasta 1915. Las matronas en Cuenca ejercieron sus funciones en una plaza específica y no en la Casa de Socorro, que era de dominio exclusivo de médicos y practicantes.

Authors: Brangier Peñailillo Víctor Mauricio , Morong Reyes Germán Adolfo
Published: July 2016

El artículo pretende estudiar la posición que ocupaba la judicialización de conflictos interpersonales por propiedad agro-ganadera, dentro de la cadena de resoluciones sociales sostenida informalmente por las partes. Se trata de un análisis de los tiempos y los vínculos que mediaban entre una y otra medida descompresora, en los primeros años de existencia de una provincia en Chile y de su implementación judicial de carácter lego, en la década  1820. La hipótesis apunta a explicar la integración de la justicia local en el seno de las vías resolutivas usadas por los actores sociales, ante tensiones surgidas en un período de disponibilidad decreciente en el uso, tenencia y propiedad de bienes agro-ganaderos. Para ello, se trabajó cualitativa y cuantitativamente una muestra de 83 expedientes criminales, seleccionados entre los tipos jurídicos que traducían disputas interpersonales por esta clase de bienes.

HiSTOReLo. Revista de Historia Regional y Local (Julio-Diciembre, Vol. 8, núm. 16) ofrece una temática variada procedente de Chile, México, Argentina y Colombia. Los artículos cubren marcos temporales distintos que se van desde el siglo XVI hasta el XX. El primer periodo corresponde a los siglos XVI y XVII con los textos de Andrea Margarita Armijo Reyes y José Rojas Galván, quienes se enfocan en los casos de Chile y México. El primero estudia la participación económica, socio-laboral y administrativa de las mujeres de Santiago de Chile a partir de documentos dotales y testamentos entre 1580 y 1650. El segundo se concentra en el éxito de la política de colonización y pacificación española, y la participación de los indios tlaxcaltecas en el norte de la Nueva Galicia a finales del siglo XVI.
Índice de tensión financiera para Costa Rica
Authors: Álvarez Corrales Cristian , Mora Gómez Carlos
Published: July 2016

En este documento se presenta un Índice de Tensión Financiera para Costa Rica. Este es un índice sintético construido utilizando datos semanales de 20 variables del sistema financiero costarricense para el periodo comprendido entre julio de 2008 y marzo de 2014. Los indicadores financieros son ponderados por medio del método de componentes principales, donde se supone que la tensión financiera es el principal factor responsable por los co-movimientos observados entre estas variables. El índice tiene como objetivo ser una medida contemporánea de la tensión en el sistema financiero y se espera que sea parte de los instrumentos analíticos a disposición de las autoridades económicas, con el fin de evaluar la estabilidad del sistema financiero costarricense. El índice construido identifica diversos episodios de tensión financiera experimentados en Costa Rica, especialmente los relacionados con la crisis financiera internacional del año 2008, la crisis de la deuda europea de los años 2011 y 2012, y el período de altas entradas de capitales a finales de 2012.
Arborescent Polypeptides for Sustained Drug Delivery
Authors: Alsehli Mosa , Gauthier Mario
Published: July 2016

Polypeptides are receiving increasing attention as building blocks to create nanostructures for biomedical applications. The first goal of this investigation was to explore the influence of the reaction conditions in the synthesis of well-defined dendritic graft (arborescent) polypeptides from amine-terminated poly(γ-benzyl L-glutamate) (PBG) chains. The optimization was carried out in terms of the reaction temperature, solvent, reaction time, and mole ratio of reactants and coupling agents. Size exclusion chromatography served to evaluate the grafting reaction in terms of grafting yield (fraction of side chains coupled with the substrate) and coupling efficiency (fraction of coupling sites consumed on the substrate). The maximum grafting yield and coupling efficiency achieved were 67% and 74%, respectively. These arborescent PBG substrates were subsequently grafted with poly(ethylene oxide) segments forming a hydrophilic shell, to obtain water-dispersible unimolecular micelles useful as delivery vehicles for doxorubicin.

Published: July 2016

New organic materials with semiconductor behavior were prepared from diphenyldiacetylene and aromatic amines with withdrawing groups by Reisch-Schulte reaction and characterized by IR, RMN spectroscopy. The obtained materials share the property of having electron withdrawing groups joint to the attached aromatic ring, it seems this feature accounts in large fashion to improve the semiconducting behavior of this kind of substances, this topic was studied by means theoretical calculations and the results are also discussed. The calculations were carried out by means the Gaussian09 software and all the involved species were geometrically optimized.
APOPTOSIS AND INFECTIOUS DISEASES

Published: July 2016

Apoptosis as immunomodulating form of cell death plays a stabilizing role in maintaining optimal number of cells in an organism. The biological essence of cell death in infectious diseases is poorly reflected, and the concept of negative and positive values of apoptosis in the pathogenesis of diseases is presented ambiguously. The review focuses on the classical caspase-dependent apoptosis of innate and adaptive immunity cells, whose reactivity is associated with the initiation of infectious processes. Some causative agents of bacterial and viral infections can be triggers or inhibitors of apoptosis in a eukaryotic host cell, avoiding the factors of the immune system. In severe infectious diseases that occur with the development of sepsis, a fatal importance has the massive apoptotic loss of lymphocytes expressed lymphocyte apoptosis that leads to immunodeficiency states and the majority of patients corresponds to premortem decrease in circulating lymphocytes. Further studies on the identification of the molecular elements whereby pathogenic agents cause the cell death effort to develop new therapeutic approaches, including inhibition of apoptosis, to prevent the progression of severe courses of infections.

Lipopolysaccharide (LPS) is used as activator and inductor of immune cells apoptosis in case of infectious processes modeling. It is not clear if LPS is direct inductor of apoptosis in human T-cells. The subpopulations of effector and naive CD4+ T-helper and CD8+ cytotoxic T lymphocytes of human peripheric blood were isolated and cultivated in presence of LPS. It has been shown that LPS was inductor of apoptosis in studying T-cells populations.
IN VITRO METHOD FOR EXPRESSION OF TOXIN PRODUCTION IN NON-TOXIGENIC CORYNEBACTERIUM SPP. WITH “SILENT” TOX-GENE
Authors: Gabrielyan S. A.
Published: July 2016

The «in vitro method» for expression of toxin-production by phenotypically non-toxigenic strains of C. diphtheriae containing the “silent” toxin gene has been developed. The method can be characterised as rapid, economical, not demanding use of experimental animals, available to practical and scientific laboratories. Optimal conditions using this method were defined: nutrient mediums, frequency rate of passages, which provided restoration of toxin production. This method allowed to restore toxin-production in 10 out of 18 tested strains of C. diphtheriae with the “silent” toxin gene. Moreover, there was an increase of toxin roduction of by C. ulcerans and C. diphtheriae var. intermedius to the level allowing to detect toxin in the standard tests. The phenotype of a toxin-producing was defined by the Elek-test and ICS (immunechromatography set).
ETHICAL AND LEGAL ASPECTS OF INFECTIONS DISEASES AND VACCINATION Part 4. The balance between universal ethical and ecoethics principles on zooanthroponosis
Authors: Kubar O. I. , Tokarevich N. K.
Published: July 2016

The current paper continued the presentation of the data on ethical, legal and social aspects of the problems connected with the study for prevention infections diseases, additionally including the wide list of infections diseases and increasing the specter of ethical problems in the science in comparision with previous publications in this aria. The investigation of the balance universal ethical principles and ecoethics in the field of zooanthroponosis has been done first time in this paper. Data of the paper are based on the scientific and professional experience of the authors both in infections diseases and bioethics and give the analysis of main international UNESCO documents on bioethics and ecoethics. The principal element that has been used by authors for analysis was the view on epidemiology of zooanthroponosis as ecological process for integration between ethiological agents of infections diseases on the real population of different animals including human beings. Such approach became the base for including the biological, social, economical, topographic and environmental factors for investigation the principals of control and prevention in the aria of zooanthroponosis. In the paper has been presented the set of both environmental principles: common and practical. Theoretical picture of the application the philosophical standards of environmental ethics has been done in real conditions of ethiology, patogenics, epidemiology, clinic, treatment and prevention such kinds of zooanthroponosis as: eastern equine encephalitis, tick borne encephalitis, leptospirosis, Q-fever, tularemia, hemolytic uremic syndrome, listeriosis, West Nile fever, pseudo-tuberculosis and others. In the frame of the understanding ideology and principless of environmental ethics such as “respect for all life forms, human and non-human” and “respect for biodiversity” in the practical situation of zooanthroponosis the priority of prevention human being and responsibility for protection the rights of future generations was shown. The same time the value of bioethical and environmental ethics for control of zooanthroponosis was demonstrated with the justice of such principals as: “safeguarding the sustainability of the biosphere”, “environmental justice”, “precautionary principle” and “Earth as global commons”. In general it was contributed substantially for understanding the necessarily of the balance in using the base principals of bioethics and environmental ethics with the priority of surveillance and control in health care.
