Authors: Corda Maria Cecilia , Viñas Mariela , Coria Marcela Karina , Vallefín Camila
Published: November 2019

En el presente trabajo se aborda la cuestión de la gestión del riesgo en relación con un tipo de biblioteca específica, la universitaria. En él se revisa bibliografía proveniente de distintos ámbitos y se vincula con la realidad de esta clase de instituciones, presentando, asimismo, el análisis de las entrevistas realizadas a las directoras de las bibliotecas pertenecientes a la Universidad Nacional de La Plata, Argentina. Dichas entrevistas tomaron diferentes ejes, tales como políticas y procedimientos, interés de las autoridades, capacitación, medidas adoptadas, factores de riesgo, entre otros. Los resultados demuestran que, si bien se han realizado algunos desarrollos específicos en este sentido, aún existe una cuenta pendiente en cuestiones vinculadas a la implementación de una gestión del riesgo en las bibliotecas universitarias de la Universidad Nacional de La Plata.
Guardianas de la sabiduría: Pedagogía de los cantos ancestrales del pueblo Embera Eyabida
Authors: Domico-Murillo Nataly
Published: November 2019

El siguiente artículo presenta los resultados de la investigación desarrollada desde y con el pueblo Embera Eyábida de Chigorodó sobre los cantos ancestrales de las mujeres y su vinculación con los espacios pedagógicos y didácticos de las escuelas indígenas. Como pregunta de investigación se planteó ¿Qué elementos pedagógicos pueden aportar los cantos ancestrales al modelo de educación propia que se ejerce dentro de las escuelas indígenas de la comunidad Embera Eyábida?El objetivo de la investigación fue recuperar cantos ancestrales o truambis de las mujeres abuelas de este pueblo indígena, para construir material pedagógico que aporte a la educación propia de los niños y niñas. El trabajo se inscribió dentro del paradigma de investigación indígena sustentando por Linda Smith y profundizó el método de investigación Embera adelantado por el lingüista indígena de pueblo Embera Dobida, Baltasar Mecha.Encontramos que existen cinco tipos de cantos ancestrales o truambis en el pueblo Embera de Chigorodó: cantos de animales, cantos de sanación, cantos de duelos, cantos de arrullos y cantos de parejas. Estos cantos ancestrales se encuentran en riesgo de desaparecer si no se realizan procesos pedagógicos que fortalezcan y visibilicen su práctica. Las amenazas del sistema dominante están desvirtuando los intereses de la niñez y las juventudes Embera, enrutándoles a asimilar perspectivas occidentales en sus prácticas culturales que afectan notoriamente el arraigo identitario.  Aprendimos que en la actualidad el grupo poblacional que practica y enseña estos conocimientos, está integrado por las mujeres Embera Eyábida, quienes a su vez son guardianas y pedagogas de la sabiduría ancestral. Se hace urgente reconocer y profundizar en sus saberes para fortalecer la memoria comunitaria del pueblo Embera.

The objective is using a clinical example to demonstrate the possibilities of intra-arterial polychemotherapy (PCT) in the combined treatment of oral squamous cell carcinoma.

Clinical case. A 43-year-old oral squamous cell carcinoma patient with metastases to cervical lymph nodes, left side (T3N2bM0, stage IV) underwent 2 courses of regional neoadjuvant intra-arterial PCT (docetaxel at a dose of 105 mg, cisplatin at a dose of 105 mg), accessed through a. lingualis. A total dose of 6,800 mg of 5-fluorouracil was administered as a 96-hour infusion. PCT induced oral mucositis of grade 2, no hematological side effects were observed. Clinical examination revealed that tumor volume decreased by 60 %. Ultrasound detected no changes in lymph nodes. Second step included resection of oral cavity bottom tissues, atypical tongue resection, marginal resection of the lower jaw on the left, radical neck dissection on the left. Histological study of the surgical material of primary tumor region as well as metastases of the cervical lymph nodes on the tumor side revealed pathomorphism of 4 grade. In the postoperative period, oral cavity and neck were irradiated from 2 sides. No signs of the disease were detected within 9 months after the combined treatment.

Conclusion. The clinical case demonstrates the high efficiency of regional intra-arterial PCT in patients with locally invasive oral squamous cell carcinoma. It seems relevant to further study its possibilities in the combined treatment of locally invasive forms of oral squamous cell carcinoma.

Published: November 2019

One of the earliest and most common adverse events of radiotherapy in patients with oropharyngeal cancers is mucositis. Radiation-induced mucositis significantly impairs the quality of life, patient compliance, and sometimes even long-term treatment outcomes. Currently, there is a wide range of drugs and techniques for the prevention and treatment of this complication. Nevertheless, these methods are not always highly effective and often have their own adverse events; therefore, the search for a universal method still continues. The present review aims to analyze the efficacy of hyaluronic acid in the prevention and treatment of oropharyngeal mucositis.

Effect of Vermicompost on Macro and Micro Nutrients of Lettuce (Lactuca Sativa Var. Crispa) Under Salt Stress Conditions
Authors: DEMİR Zeynep , KIRAN Sevinç
Published: November 2019

This study was conducted in order to determine the
effect of vermicompost (V) on macro and micro nutrients of lettuce (Lactuca sativa Var. crispa) exposed to salt stress (SS). V doses; 0 (V0), 2.5% (V1) and
5% (V2) (w/w) and salt stress levels; control (SS0) (0 dS m-1 NaCl),
medium salt stress (SS4) (4 dS m-1 NaCl), severe salt stress (SS8)
(8 dS m-1 NaCl) were used. In order to make evaluation in terms of
the nutrients, plants were kept under controlled conditions (relative
humidity 50-55%, daytime/night time temperature 24/20 °C) in
the greenhouse for 46 days (May 24 and July 10, 2017).
While the medium and severe salt stress decreased the P, K, Mg, Fe, Mn and Zn
concentrations of plants significantly, compared to the control, it caused
increase in N and Na concentration. While Na decreased due to the V, other
mineral element concentrations increased significantly and these increases were
found more effective in 5% V application. The effect of SS x V interaction was
statistically significant in terms of N, P, Mg, Na, Fe, Mn and Zn, whereas it
was found insignificant for K, Ca and Cu. It was shown that in lettuce growing,
V applications in areas with salinity problems could contribute to reducing the
toxic effects of salinity on the plant and improving the imbalance in nutrient
intake.
Effects of task structure on young learners’ writing quality
Authors: Cheung Yin Ling , Jang Hari
Published: November 2019

In the past decade, research has yielded mixed results regarding the relationship between task complexity and writing quality. Some studies have suggested that an increase in task complexity results in the improvement of syntactic complexity, accuracy and fluency. Other studies have demonstrated partial improvement in fluency, accuracy, syntactic complexity, or lexical complexity. This study examines the impact of task structure on writing quality among English-as-a-second-language (ESL) young learners. The analysis is based on 236 ESL fourth-grade pupils’ narrative compositions. Using the Limited Attention Capacity Model and the Cognitive Hypothesis, the analysis revealed that Primary Four pupils wrote significantly longer and syntactically more complex texts in structured tasks, and they scored higher in lexical variety in unstructured tasks. The accuracy of writing did not vary significantly based on task structure. The study provides new empirical evidence for the argument that task structure affects ESL young learners’ writing performance in terms of syntactic complexity, fluency, and lexical variety. The findings contribute new knowledge to the field of second language writing. In particular, how task structures influence writing quality and how such knowledge can inform writing pedagogy and the evaluation of students’ written work.
Narrowing the Gap between EFL and ESL:
Authors: Chen Xin
Published: November 2019

The sharp increasing number of international students in the U.S. has warranted more research into the academic literacy development of those students whose first language is not English. A great number of studies have found that how to socialize themselves into the new discourse communities at university remains a challenge for most international students because of language and cultural barriers. The gap between learning the English language in EFL contexts and using the language in ESL contexts also becomes an issue in international students’ academic performance that needs to be addressed. This case study examines how a graduate student from Korea (an EFL country) developed her academic English when pursuing her degree in the U.S. (an ESL context for her). The research demonstrated her strategies of surviving the academic life despite the language limitations and investigated the factors that influenced her language development. Implications for how to support international graduate students in improving linguistic and cross-cultural competences are discussed.

Authors: Pivovarova M. V. , Gladkiy I. L.
Published: November 2019

Currently, operation of gas turbine engines takes place in the aggressive medium of the atmosphere of some climatic regions. As a consequence, this may cause fast degradation of the strength properties of parts of gas turbine equipment and their subsequent premature failure. The problem of determining the life of gas turbine engine components under corrosive exposure is vital. We present an analysis of the state of the art in the field of assessment of gas turbine engine component life under the influence of corrosive environment in Russia and abroad. UEC-Aviadvigatel, FSUE VIAM and NPO TSKTI JSC formulated approaches to the development of the lifing process for engine parts operating in corrosive environment.

Authors: Privalov A. E. , Bugaichenko P. Yu.
Published: November 2019

The article presents a solution of the problem of substantiating the architecture of an interactive information model for the launch preparation of an integrated launch vehicle (ILV). The relevance of the research is due to the complexity and high dynamics of the ILV launch preparation process, as well as the latest achievements in the field of information modeling and decision support theory. The aim of the research is to raise the situational awareness of the decision maker in managing the process of preparing ILV for launch. The process of formation of situational awareness as an integral part of the decision-making process is analyzed. On the basis of this analysis a model of an indicator of the effectiveness of situational awareness formation is proposed for the first time. A model for evaluating the effectiveness of the process under study is developed on the basis of the mathematical apparatus of the theory of continuous-time Markov chains. The results of numerical experiments confirming the adequacy of the model and making it possible to state the quantitative requirements for the process of formation of situational awareness, ensuring its maximum efficiency, are presented. The tasks of the information system aimed at satisfying the requirements are stated, and the architecture of the information model of the ILV launch preparation process is developed. The research results can be used to justify the quantitative requirements for the developed information models of the launch situation at the stage of development of technical specifications.
Сalculated analysis of the influence of operation and design factors on the parameters of oxygen-hydrogen low-thrust rocket engines
Authors: Ryzhkov V. V. , Morozov I. I.
Published: November 2019

The paper presents the results of calculating thermodynamic and thermophysical properties of the combustion products of gaseous oxygen-hydrogen fuel according to the ideal LRE model taking into account the phase state of the components, as well as the parameters of a low-thrust engine according to the model of computational gas dynamics to ensure the selection of operation and design factors that define the design of a thruster for advanced aerospace objects. It is shown that ideal models can be used for the selection of some parameters, such as: the excess oxidant ratio, the pressure in the combustion chamber, the geometric degree of area expansion ratio. High-level computational gas dynamics models need to be used for the selection of some of the parameters of the engine to be designed, such as: design parameters of the propellant injection pattern, reduced length of the combustion chamber and some others. Air specific impulse was used as the selection criterion. The obtained calculation data allow one to choose the main parameters of the engine being designed with account for real processes in the combustion chamber and the nozzle of the engine.
Determining the rheological properties of viscoelastic materials by the values of creep strain
Authors: Ivanov E. Yu. , Kirpichev V. A.
Published: November 2019

Determination of creep strain arising due to stresses acting up to the moment of time t is considered. The phenomenon of constant-stress creep is described. A method is proposed to determine the parameters of the Arutyunyan creep kernel selected to describe the behavior of a material using two creep curves of a material with viscoelastic properties and nonlinear dependence of creep strain on the stress. In addition, the constant in the expression describing nonlinear dependence of creep strain on the stress is defined. The AMg6M alloy, widely used in the design of aerospace products, was chosen as the material to be analyzed. The tests were carried out on samples 3 mm thick at strains of 65MPa and 156.9MPa. According to the results of testing samples of materials on the test bench of Samara University creep curves were obtained. By determining the parameters of the approximation of the Arutyunyan kernel and the parameter included in the expression of nonlinear dependence of creep strain on the stress, it is possible to determine the value of the creep strain of the material for arbitrary values of stress and time. Comparison of the experimental and calculated creep curves for the AMg6M alloy confirms the validity of determination of the rheological characteristics of the tested material.

Published: November 2019

This paper presents the results of theoretical and experimental research of a prototype of a propulsion system for periodical low-Earth orbit correction of research-and-educational nanosatellites. For that purpose, the prototype is to provide at least 20 m/s relative velocity for a 3U CubeSat with a mass not exceeding 4.5 kg. The personnel and environment safety were taken into account during testing and operation along with the ability to be launched as an associated payload by a Soyuz-series launch vehicle or from the ISS. An electro-thermal propulsion system (ResistoJet) was designed with nonfreezing mixture of ethanol and distilled water used as the working fluid. It is shown that a standard vehicle power system is capable of initiating one corrective thrust impulse per orbit with flight velocity change of about 0.1 m/s by introducing pulse energy storage units and allocating sufficient time for their charging in the flight profile. The propulsion system prototype was tested in atmospheric conditions. For that purpose shortened atmospheric nozzles were used. Testing was carried out using a zero-torque test-bench with high-speed cameras. The measured thrust value was in agreement with the calculated value of 44 mN.
Gas dynamic calculation of detonation in constant-cross-section ducts
Authors: Grigoriev A. V. , Rudakov O. A. , Solovieva A. V.
Published: November 2019

The paper presents a computational method with the use of gas-dynamic functions of parameters of detonation in a one-dimensional subsonic flow of ideal gas behind the shock wave propagating in chemically active air-and-fuel mixture in a uniform-cross-section duct, where the resultant of normal pressure forces acting on its side surface is equal to zero. Stabilization of the shock wave is provided by the onset of thermal crisis with the air-and-fuel mixture combustion heat supply to the gas behind the wave. In this case the value of the specific speed of the combustion products is equal to the critical one. The solution of the total-impulse equation considering the above mentioned peculiarities of the flow in a uniform-cross-section duct establishes clear correlation of the specific speed of the stabilized shock wave to the rate of rise of the temperature of the gas behind it, which gives an opportunity to determine all detonation parameters. The shock wave can be initiated by the detonation of an explosive substance and carries a huge amount of energy. It is shown that the shock wave can be obtained only if the source of small disturbances itself moves at the supersonic speed. It is shown that total pressure behind the shock wave decreases significantly and the entropy increases due to the wave losses, whereas the static pressure increases significantly. An explanation of this effect is given. A formula for calculating the rate of gas temperature rise was derived as a function of the specific speed of the shock wave, the air-and-fuel mixture heat value and the heat availability factor that designates the dissociation of the combustion products and heat loss through the duct wall under specified initial conditions. The reliability of the method of calculating detonation was experimentally substantiated. The work is currently important for the evaluation of the detonation engine efficiency.

Authors: Alhelo Amjad , Samara Bashar
Published: November 2019

Aim: to evaluate awareness and the use of evidence-based medicine resources among physicians in Jordan. 

Method: A cross-sectional study by internet was performed among 517 doctors who were responsive from a total of 717 doctors, a total of 72.1% response rate. Doctors from all specialties were contacted from a Facebook group called doctors café in Jordan. A questionnaire was given to each one of them to measure their awareness and use of Evidence based database.  

Result: From 517 physicians 377 they are using evidenced based resources frequently, and 91 using resources but not frequently and 49 not using evidence-based resources. The resource that was mostly used by the doctors was PubMed, followed by other resources such as Up to date, National Guideline Clearinghouse, Medscape, BMJ best practice, e-books and other online journals for published papers. The Cochrane Library was surprisingly not so familiar amongst physicians.

Conclusion: There is good awareness about EBM among physicians in Jordan, and that benefits health care in Jordan.
Математическая модель инжекции сероводорода в пласт, частично насыщенный водой
Authors: Хасанов Марат Камилович
Published: November 2019

Актуальность исследования связана с разработкой теоретических основ технологий подземного захоронения, вырабатываемого промышленными объектами сероводорода с целью снижения его эмиссии в атмосферу. Рассматривается метод утилизации сероводорода в газогидратном состоянии, в котором одинаковое количество газа может храниться при значительно меньших значениях давления. Целью исследования является выяснение особенностей протекания процесса образования газового гидрата H 2 S при инжекции жидкого сероводорода в пористый резервуар. Объект: пористый пласт, насыщенный нефтью и водой, исходное давление которого ниже равновесного давления образования газогидрата сероводорода. Методы исследования. На основе уравнений механики сплошной среды построена математическая модель тепломассопереноса в природном пласте, сопровождающегося образованием газогидрата сероводорода. Принято, что в рассматриваемом случае в пласте возникают три характерные зоны и соответственно два подвижных межфазных фронта - между первой и второй зонами, где происходит полный переход воды в газогидратное состояние (фронт гидратообразования), и между второй и третьей зонами, где осуществляется вытеснение нефти сероводородом (фронт вытеснения). Методом сведения к автомодельной переменной построены аналитические решения для безразмерных значений давления и температуры в каждой из трех областей пласта. Исследованы зависимости координаты и температуры межфазных границ от температуры закачиваемого сероводорода и исходной температуры пласта. Результаты. Установлено, что с повышением начальной температуры пласта и температуры инжектируемого жидкого сероводорода координата фронта образования газогидрата H 2 S уменьшается, а температура фронта вытеснения нефти сероводородом увеличивается. Показано, что при достаточно низких значениях температуры пласта и инжектируемого сероводорода может происходить выравнивание координат фронтов гидратообразования и вытеснения. На плоскости параметров «температура инжекции - начальная температура пласта» построены карты решений, т. е. критические диаграммы, определяющие существование режима, при котором фронт вытеснения нефти сероводородом опережает фронт образования газогидрата H 2 S.

Authors: Tacca Huamán Daniel Rubén , Tacca Huamán Ana Luisa , Alva Rodriguez Miguel Angel
Published: November 2019

En los últimos años la didáctica universitaria se está adaptando a los estilos de aprendizaje de los estudiantes y la neurociencia se ha convertido en una disciplina que aporta gran cantidad de información sobre el funcionamiento del cerebro, sus implicancias en la construcción del conocimiento y la importancia de considerar los aspectos cognitivos, afectivos y sociales inmersos en el proceso de aprendizaje. El propósito principal de la investigación fue conocer la relación que existe entre las estrategias neurodidácticas del docente con la satisfacción y el rendimiento académico en los estudiantes de una universidad de Lima, Perú. El estudio fue cuantitativo, correlacional, transversal y con una muestra de 311 estudiantes de los dos primeros años de formación universitaria. Los resultados indican que las estrategias neurodidácticas se correlacionan positivamente con la satisfacción y el rendimiento académico (.72 y .51 respectivamente). Asimismo, se presentó una relación moderada entre la satisfacción y el rendimiento académico (.45). En cuanto a los tipos de estrategias neurodidácticas se ha encontrado que los docentes evaluados usan con mayor frecuencia las estrategias metodológicas. Sin embargo se ha observado que las estrategias socioemocionales presentan un coeficiente de correlación más alto con la satisfacción (.63), en comparación con otros tipos de estrategias.
Sound Financial Management and Happiness: Economic Pressure and Relationship Satisfaction as Mediators
Authors: Spuhlera Bryan K. , Dew Jeffrey
Published: November 2019

This study examines the relationship between sound financial management behaviors and happiness using a national sample of adults collected in 2009 (N = 1,014). We used Maslow's hierarchy of needs (1943) as a theoretical framework to examine associations between sound financial management behavior, economic pressure, relationship satisfaction, and happiness. Findings suggested that economic pressure and relationship satisfaction both mediated the association between sound financial management and happiness, but the mediator effects were only partial. That is, even after accounting for participants' actual financial context, feelings of economic pressure, and relationship satisfaction, a positive association between sound financial management behavior and happiness remained.
The Effect of Parental Warmth During Adolescence on Later Income and Subjective Well-Being: Comparing Sexual Minority and Heterosexual Young Adults
Authors: Lawson Derek R. , Scroggs Barrett , Vennum Amber
Published: November 2019

This study explores the influence of parental warmth during adolescence on financial experiences and well-being across the transition to adulthood. Given the poorer financial outcomes and more complicated parental relationships reported by sexual minorities compared to their sexual majority counterparts, the present study examined the moderating impact of sexual orientation during emerging adulthood. The current study used three waves of data from the National Longitudinal Study of Adolescent eHealth. Groups were categorized as identifying as either heterosexual (n = 4,337) or nonheterosexual (referred to as “sexual minorities,” n = 482), resulting in an overall sample size of (n = 4,819). Using a multiple group structural equation model, results indicated that while mediated by future financial expectations, parental warmth during adolescence positively predicted income and well-being during adulthood in both sexual minority and heterosexual individuals. Significant differences were found between these two groups. Parental warmth was a stronger predictor of later well-being in sexual minority individuals. Implications for practitioners are discussed including the need for further cultural competency related to sexual minority populations.
Poética del espacio aumentado en la obra de Paul Sermón

Published: November 2019

En este trabajo se concibe como el principio de otras formas de comunicación humana, el concepto de comunicación intersubjetiva comparte el objeto empírico de la comunicación interpersonal pero se diferencia de ella en perspectiva, destacando la construcción social inherente al fenómeno. Para comprender la comunicación intersubjetiva como objeto de investigación en nuestro caso en la obra de Sermon, más que enlazar con el concepto de sujeto o de subjetividad, hay que enlazar directamente al concepto de “intersubjetividad” que se relaciona con la posibilidad de intercambio de perspectivas respaldando la construcción social de un mundo compartido, una cultura abierta y dinámica de todos y para todos y que como veremos podemos comprobar  y experimentar en las obras de Sermon.

“E tudo o resto é paisagem…”
Authors: Lambert Maria de Fátima
Published: November 2019

O texto compila ideias autónomas que inquirem sobre viagem, enquanto ímpeto para recolher, armazenar e conceber a paisagem, organizando sua dimensão imagética em pluralidade e polissemia. As tipologias de paisagem acompanham-se e distinguem-se, decorrendo das finalidades autorais que as questionam e interseccionam. O conceito de paisagem acolhe modelos estéticos e artísticos que, simultaneamente, transformam o pensamento crítico e historiográfico que lhe tem assistido ao longo dos últimos dois séculos, muito em particular. Pretende-se, assim, contribuir, quer para a formulação de novas interrogações, quer para a aferição de algumas conclusões parcelares; promulgando novas aceções e definições dos três conceitos-chave consolidados pela memória: paisagem, viagem, imagem.

Procurarei seguir pelo caminho ilimitado da escrita em busca dum naufrágio imperfeito ocorrido no oceano tumultuoso da poesia e da arte, um naufrágio imprevisível enxergado a partir de terra firme, que guarda dentro de si memórias de acontecimentos que subrepticiamente nos olham e desafiam na busca incessante de verdades impensáveis e experiências singulares que habitam no seio da natureza e no coração das obras criadas pelo espírito do homem. Natureza e obra, corpo e máquina, amor e sexualidade, saber e religião, orgânico e abstracto são multiplicidades binárias singulares que colidem entre si além de quase sempre entrarem em ruptura com os territórios e as culturas com que têm de se confrontar.

Este artigo discute as dificuldades enfrentadas pela arte contemporânea, em especial aquela de cunho colaborativo, diante de novas demandas que clamam por uma maior inserção da arte no campo social. A partir da interlocução com autores como Claire Bishop, Hans Haacke, Linda Nochlin, Stephen Wright e Jacques Rancière, entre outros, procuramos investigar aspectos que compõem o cenário de certa encruzilhada que se apresenta para as práticas de arte colaborativa na contemporaneidade que, por sua vez, precisam encontrar os termos de sua articulação com o campo social e com o campo político na busca por uma presença qualificada da arte no mundo.
Hydrogen Sulfide Exposure to Public Health Risk Around Cibereum Landfill Area at Banjar City
Authors: Rufaedah Arie Ardiyanti
Published: November 2019

The process of spoilage of waste in the landfill produces air pollutant gases such as hydrogen sulfide (H2S) which was a colorless gas, highly flammable, and has a characteristic rotten egg odor. Communities around TPA who were continuously exposed to H2S gas has very at risk of experiencing health problems. The main entrance of H2S gas through the respiratory system so that it was quickly absorbed by the lungs rather than exposure through the mouth. This study aims to analyze the great health risks arising from exposure to hydrogen sulfide gas at the Cibeureum landfill in Banjar City. This research was a descriptive-analytic type with cross-sectional study design and it was analyzed with an environmental health risk assessment (EHRA) approach. The results of H2S concentration measurements were 0,004 ppm and still below the 0,02 ppm standard. Exposure projections indicate that people in the surrounding areas do not yet have non-carcinogenic risks (0,42≤1). The safe duration of exposure is 24 years. If residents still live around the landfill for more than 24 years, it will endanger them and cause non-carcinogenic health risks. Complaints caused by civilians around the landfill consist of coughing, headaches, colds, shortness of breath, chest pain, and sore throat.

Periplaneta Americana has long been acknowledged as mechanical vector for infectious diseases. Baiting gel is considered as an advantegous mechanical vector control because it is relatively affordable and convenient for users. However, further studies to understand dose-response effects and effective ingredient composition still limited. Therefore, the aim of this research was to analyze the effect of the combination doses of baiting gel with active ingredients boric acid and sulfur materials on Periplaneta americana mortality. This research was true experimental with Randomized Controlled Trial (RCT) study design. The researchers intervened the formula of baiting gel with a combination of boric acid and sulfur at different doses. The treatment of baiting gel at various dose levels produced a significant difference in the mortality of Periplaneta americana imago. Partial eta squared values showed the model design formed and the dose of baiting gel that had been applied had an effect on the mortality of Periplaneta americana imago at 90.4%. The observed power results show that the percentage to reject the hypothesis H0 for all diversity is 100%. The most effective dose in killing Periplaneta Americana cockroaches is a combination of Boric Acid: 10 grams and Sulfur: 0.25 grams. The conclusion of this research was to it is recommended to determine the weight of baiting gel before and after the application in order to optimize the results.

The mucopolysaccharidoses (MPS) are a group of 11 lysosomal storage diseases (LSDs) produced by mutations in the enzymes involved in the lysosomal catabolism of glycosaminoglycans. Most of the mutations affecting these enzymes may lead to changes in processing, folding, glycosylation, pH stability, protein aggregation, and defective transport to the lysosomes. The use of small molecules, called pharmacological chaperones (PCs), that can restore the folding, trafficking and biological activity of mutated enzymes has been extensively explored in LSDs as a therapeutic alternative. PCs have the advantage of wide tissue distribution, potential oral administration, lower production cost, and fewer issues of immunogenicity. In this paper, we will review the advances in the identification and characterization of PCs for the MPS. These molecules, mainly based in molecules mimicking the enzyme substrates, have been described for MPS II, IVA, and IVB, showing a mutation-dependent enhancement of the mutated enzymes. Although the results show the potential of this strategy, further studies should focus in the development of disease-specific cellular models that allow a proper screening and evaluation of the identified PCs. In addition, in vivo evaluation, both pre-clinical and clinical, should be performed, before they can become a real therapeutic strategy for the treatment of MPS patients.
An Ontological and Semantic Foundation for Safety and Security Science
Authors: Blokland Peter , Reniers Genserik
Published: November 2019

When discussing the concepts of risk, safety, and security, people have an intuitive understanding of what these concepts mean, and, to a certain level, this understanding is universal. However, when delving into the real meaning of these concepts, one is likely to fall into semantic debates and ontological discussions. In industrial parks, it is important that (risk) managers from dierent companies, belonging to one and the same park, have the same understanding of the concepts of risk, safety, and security. It is even important that all companies in all industrial parks share a common understanding regarding these issues. As such, this paper explores the similarities and dierences behind the perceptions of these concepts, to come to a fundamental understanding of risk, safety, and security, proposing a semantic and ontological ground for safety and security science, based on an etymological and etiological study of the concepts of risk and safety. The foundation has been induced by the semantics used in the ISO 31000 risk management guidance standard. Hence, this article proposes a coherent, standardized set of concepts and definitions with a focus on the notion “objectives” that can be used as an ontological foundation for safety and security science, linking “objectives” with the concepts of safety, security, risk, performance and also failure and success, theoretically allowing for an increasingly more precise understanding and measurement of (un)safety across the whole range of individuals, sectors and organizations, or even society as a whole.

The article is devoted to the assessment of the network community as a collective subject, as a group of interconnected and interdependent persons performing joint activities. According to the main research hypothesis, various forms of group subjectness, which determine its readiness for joint activities, are manifested in the discourse of the network community. Discourse constitutes a network community, mediates the interaction of its participants, represents ideas about the world, values, relationships, attitudes, sets patterns of behavior. A procedure is proposed for identifying discernible traces of the subjectness of a network community at various levels (lexical, semantic, content-analytical scales, etc.). The subjective structure of the network community is described based on experts’ implicit representations. The revealed components of the subjectness of network communities are compared with the characteristics of the subjectness of offline social groups. It is shown that the structure of the subjectness of network communities for some components is similar to the structure of the characteristics of the subjectness of offline social groups: the discourse of the network community represents a discussion of joint activities, group norms and values, problems of civic identity. The specificity of network communities’ subjectness is revealed, which is manifested in the positive support of communication within the community, the identification and support of distinction between “us” and “them”. Two models of the relationship between discursive features and the construct “subjectness” are compared: additive-cumulative and additive. The equivalence of models is established based on the discriminativeness and the level of consistency with expert evaluation by external criteria.

The aim of performed studies was to fabricate an antibacterial and degradable scaffold that may be used in the field of skin regeneration. To reach the degradation criterion the biocompatible polyurethane (PUR), obtained by using amorphous macrodiol α,ω-dihydroxy(ethylene-butylene adipate) macrodiol (PEBA), was used and processed with so-called “fast-degradable” polymer polylactide (PLA) (5 wt% or 10 wt%). To meet the antibacterial requirement obtained hybrid PUR-PLA scaffolds (HPPS) were modified with ciprofloxacin (Cipro) (2 wt% or 5 wt%), the fluoroquinolone antibiotic inhibiting growth of bacteria such as Pseudomonas aeruginosa, Escherichia Coli and Staphylococcus aureus, which are main cause of wound infections. Obtained unmodified and Cipro-modified HPPS were studied towards their chemical composition to detect presence or absence of characteristic functional groups of PUR, PLA and Cipro, and as well to indicate the participation of hydrogen bonds in the HPPS structure in dependence on PLA addition and ciprofloxacin modification. Mechanical properties were studied to determine the possible application of HPPS as a skin tissue scaffold. Scanning electron microscopy (SEM) was used to study morphology of unmodified and Cipro-modified HPPS and to performed elementary analysis by using energy-dispersive x-ray spectroscopy (EDX) of obtained materials. Finally, the microbiological tests were performed to indicate the antibacterial effect of Cipro-modified HPPS on S.aureus growth. Performed studies showed that Cipro-modified HPPS, obtained by using 5 % of PLA, possess suitable mechanical characteristic, morphology, degradation rate and demanded antimicrobial properties to be further developed as a potential scaffolds for skin tissue engineering.
