Published: June 2019

The aim of this research was to assess the nutraceutical potential of Hura crepitans seed oil in food chemi- stry. For that, we determined the phytochemical composition, physicochemical parameters, mineral composition, as well as proximates of the oil under study. The yield of the oil obtained by the Soxhlet method was 47.8 ± 0.2%. According to the phytochemical screening result, the oil contained saponin, alkaloid, terpenoids, steroids, and cardenolides. Quantitative analysis of proximates for the Hura crepitans seed oil displayed 10.1 ± 0.4% of protein,

19.4 ± 0.1% of crude fibres, 14.5 ± 0.5% of carbohydrates, 5.3 ± 0.2% of water, and 2.9 ± 0.1% of ash. Some selected physicochemical parameters such as refractive index, pH, and specific gravity were 1.47; 5.2; and 0.80, respectively. Cloud point was 6.20°C. Metal content determination revealed the presence of mineral substances such as magne- sium (119.51 ± 0.25 mg/kg), potassium (4.25 ± 0.04 ppm), iron (4.01 ± 0.03 mg/kg), manganese (3.66 ± 0.02 ppm), so- dium (2.18 ± 0.02 ppm), calcium (0.11 ± 0.001 ppm), zinc (0.04 ± 0.001 µg/g), and cadmium (0.0028 ± 0.0004 mg/kg). However, such minerals as nickel and lead were not detected. The structural analyse was carried out based on phy- sicochemical properties and spectroscopic data of the Hura crepitans seed oil. The results of the research proved the nutraceutical potential of this oil to use as raw materials in various areas of industry.
Developing freeze-dried bioproducts for the Russian military in the Arctic
Authors: Artyukhova Svetlana , Kozlova Oksana , Tolstoguzova Tatiana
Published: June 2019

The Arctic is currently a strategic region of Russia and it requires military protection. Good nutrition is a prerequisite for successful performance of the servicemen in such extreme conditions. The Russian armed forces do not have a special ration for the Arctic region. The existing rations lack products enriched with biologically ac- tive substances, probiotics, prebiotics, or vitamin and mineral complexes. Subcaloric nutrition, even with short-term physical exertion, in combination with low temperatures deprives the human body of vitamins and minerals. There- fore, the development of freeze-dried bioproducts with functional properties is highly relevant. This article presents the results of a study aimed to develop new freeze-dried milk-based bioproducts for the Russian military in the Arc- tic. For this, we created a microbial consortium of lactic acid bacteria with a wide spectrum of antimicrobial activity. We also used a range of functional ingredients, namely pectin, pine nut meal, a ‘Lactobel’ prebiotic protein-and-car- bohydrate product, rowan puree, and rosehip syrup in the amounts established during the study. The new freeze- dried milk-based bioproducts named ‘Pobeda’, enriched with combiotics and metabiotics, will provide the Russian military with better nutrition in the extreme conditions of the Arctic.

Published: June 2019

Rice is now the main food for about 35 million people in Nigeria, and consumption is increasing faster than that of any other food crop in many countries in Africa. This study provided essential engineering data on the physical properties of selected varieties of local rice in Nigeria. Some selected physical properties of Igbemo, Ofa- da and Abakaliki rice varieties at harvest, market, and storage conditions were evaluated as a function of moisture content. The latter ranged from 12.38 to 25.69% (dry base). We also determined the physical properties of the rice samples, such as moisture content, linear dimensions, geometric mean diameter, arithmetic mean diameter, surface area, aspect ratio, sphericity, bulk density, and hundred kernel weights. A result of the linear dimensions for the major diameter was 8.4–10.3 mm, 6.4–6.55 mm, and 5.9–7.4 mm for harvested, marketed, and stored rice, respec- tively. The minor diameter ranged from 2.70 to 3.29 mm, 2.49 to 2.63 mm, and 2.56 to 2.74 mm, and the intermedi- ate diameter of the rice varieties at harvest, market, and storage conditions was 1.92–2.29 mm, 1.90–2.02 mm, and 1.87–1.99 mm, respectively. Depending on the conditions and varieties, the bulk density, true density, and porosity, was observed to be between 0.59 to 0.90 g/cm3, 2.28 to 5.57 g/cm3 and 70.38 to 85.35% respectively.

Police officers are first responder with special lay category. Police have an additional duty to provide first aid to victims of accidents because medical personnel are still limited to provide help. Certainly the police have their own experience that needs to be explored to find out what expectations are for their daily activities in helping victims of current traffic accidents. This study used a qualitative design of hermeneutic phenomenology to explore and interpret police officers' expectations as first responder in traffic accident victims. The number of participants as many as 5 people who served at the Post Purwodadi Lands Area Pasuruan Police. Instruments in this study that researchers as a core instrument and other supporting tools that is in the form of a netbook equipped with a camtasia studio voice recorder program, ballpoint pen, and paper for field notes. Data collected through indepth interview processed into tranksrip and then analyzed by using method Dikelmann et al (1989). The results of the research are two cross-sectoral cooperation and the need for an award. The theme of cross-sector cooperation is built on two sub themes, namely cooperation with hospitals and cooperation with the community. The theme of need for an award is built by a sub theme that needs rewards. The conclusion of this research is that police officers have big expectation to the related parties to give the best first aid for the safety of traffic accident victims. Thus, it is hoped that the cooperation will be strengthened to support police officers in helping victims of traffic accidents to reduce the mortality and morbidity of traffic accident victims.

Published: June 2019

This article is a summary of the updated version of the review article “The impact of the space experiments on our knowledge of the physics of the Universe” (Giovannelli & Sabau-Graziati 2004: GSG2004) and subsequent slow updating (Giovannelli 2013; Giovannelli & Sabau-Graziati 2012a, 2014a,b, 2015, 2016a,b). We will go along different stages of the evolution of our Universe discussing briefly several examples of results that, in accordance with our opinion, are the pillars carrying the Bridge between the Big Bang and Biology. A significant part of these results come from great experiments in Earth or from space. Similarly, small experiments on Earth or in space have provided—and will provide—significant results. Due to the limited extension of this work and according to our knowledge, we have made a strict selection of the topics.

ResumenEn la costa de Campeche se puede encontrar aproximadamente el 30% de todos de mamíferos acuáticos documentados para el país; de estas especies, 13 son estrictamente marinas. La “ballena Minke” y la “peponocéfala o calderón pigmeo” han sido registradas en la parte norte del Golfo de México y para las costas de México son escasos los registros y más aún los varamientos vivos. Los días 4 y 5 de octubre de 2014 en el poblado de Champotón Campeche se varó viva una ballena Minke Balaenoptera acutorostrata. Su longitud total se estimó entre 4-5 m., asumiendo que se trataba de un subadulto, se regresó viva mar adentro. Por otra parte, del día 8 julio 2017 se varó una Peponocephala electra en Punta Xen, Champotón, Campeche. Se enterró en la playa de acuerdo con los procedimientos de profepa. Solo había registros previos de varamientos y avistamientos de estas dos especies en la parte norte del Golfo de México y el varamiento de una cría de B. acutorostrata en Celestún Yucatán, por lo que estos son los primeros registros para la costa de para ambas especies, lo cual es importante como contribución al acervo de diversidad de mamíferos acuáticos tanto para el estado como para el sur del Golfo de México.Palabras clave: Ballena Minke, Campeche, Peponocéfala, primeros registros, varamiento vivo.AbstractThe coast of Campeche registers approximately 30% of all aquatic mammals documented for Mexico; of these species, 13 are strictly marine.

Authors: Silvani Indiamara De Oliveira Flores Dal Magro , Grasel Eliane , Pansera Suelen
Published: June 2019

Introdução: nas indústrias que utilizam a madeira como matéria-prima, várias partículas estão suspensas no ar e o ambiente é rico em substâncias químicas e partículas orgânicas. O trato respiratório está diretamente em contato com o meio ambiente e acredita-se que a inalação de aerodispersoides possa causar diferentes tipos de respostas ou dano local no organismo. Durante o processamento da madeira nos seus vários tipos de emprego, finas partículas são produzidas. O tamanho das partículas de poeira tem entre 1,3 a 33 micrômetros (μm). A reação pela poeira da madeira é frequentemente encontrada em carpinteiros, marceneiros, serradores e polidores. Objetivo: traçar o perfil respiratório por meio da espirometria dos trabalhadores expostos à poeira de madeira da indústria moveleira do município de Coronel Freitas-SC. Materiais e métodos: foi realizado um estudo com 120 testes espirométricos dos trabalhadores das indústrias de móveis do município, atendidos durante o período de um ano, entre 2006 e 2007, vinculados a várias funções com exposição à poeira da madeira. Resultados: os testes demonstram que apenas 1,67% está com alteração na Capacidade Vital, Capacidade Vital Forçada, Volume Expiratório Forçado no primeiro segundo e a Ventilação Voluntária Máxima. A exposição à poeira da madeira pode contribuir para problemas respiratórios, mas a prevalência da normalidade nas espirometrias está presente na amostra estudada, com 6,66% dos indivíduos com distúrbios ventilatórios. Porém, ressalta-se a necessidade de um trabalho preventivo nas indústrias de móveis, visando à redução da exposição do trabalhador à poeira, diminuindo assim o risco de futuras patologias.

Authors: Güvenç Özge
Published: June 2019

Doris Lessing’in The Temptation of Jack Orkney başlıklı kısa öykü kitabından alınan “An Old Woman and Her Cat” adlı öykü, yaşlı ve evsiz bir kadının çeşitli mekanlardaki gezgin deneyimlerini ve kedisiyle birlikte kötü hayat koşullarında verdiği yaşam mücadelesini anlatmaktadır. Bu kadın kahramanın geçici olarak kaldığı sosyal konutlar, gecekondu mahallesinde bir oda ve zengin muhitte harap olmuş bir daire gibi mekanlar, insanların kendilerini ait hissettikleri evlerden değildir. Aksine bu mekanlar yaşlı kadının herhangi bir sıcaklık hissi ve bağlılık duygusu olmaksızın kısa süreliğine kişiselleştirdiği sığınaklardır. Kadın kahramanın ve kedisinin çevreleriyle olan ilişkilerine odaklanmak, mekan ve gezgin kavramlarını Henri Lefebvre’in algılanan, tasarlanan ve yaşanan mekan üçlemesi ve Rosi Bradiotti’nin gezgin kuramı bakımından incelemeyi mümkün kılmaktadır. Bu yaklaşım diğer bir yandan, büyük bir şehirde yaşlı bir kadın ve kedisinin yaşam savaşını görmezden gelen sosyal kaideler ve değerleri açığa çıkarır. Bundan dolayı bu çalışmanın amacı, sadece Londra’daki geçici yerlerin fiziksel özellikleri ile yoksul ve evsizleri zenginden ayıran mekan anlayışını değil, aynı zamanda bu yaşlı kadının kendisi için çevresindeki harabe yerleri yaşanan alternatif mekanlara dönüştürdüğünü tartışmaktır.
A Historical Evaluation of the Single Audit: Thirty Years from Initial Legislation to Uniform Guidance
Authors: Tassin Kerri L. , Waymire Tammy R. , Hines Christopher S.
Published: June 2019

The U.S. government, through federal granting agencies (grantors), awards grants to state/local governments and nonprofit organizations (grantees) to meet national objectives. Since its initial legislation in 1984, the single audit has been used as a mechanism for ensuring accountability with these federal grants. Despite the consistent goal of accountability, concerns with single audit quality (i.e., whether audits reach appropriate conclusions) persist. In this historical evaluation of the single audit, we examine the major legislative and administrative developments associated with the single audit including (1) Single Audit Act of 1984, (2) Single Audit Act Amendments of 1996, (3) National Single Audit Sampling Project in 2007, (4) Improper Payments Initiative in 2009, and (5) administrative consolidation of all single audit circulars with Uniform Guidance issued in 2013. Understanding these developments should be helpful to researchers and policymakers in directing studies designed to better understand and improve single audit quality.

Published: June 2019

The objective of this paper is to empirically investigate the applicability of the asset pricing model in a portfolio made up of groups of countries, the G20 for this case. In the meantime, it was intended to compare a complete sample of 14 constituent countries of the group, a subsample of four countries belonging to the BRICS and another of the countries that do not belong. The survey sample consisted of long-term interest rate data from these countries collected in the OECD database and also from the Central Bank of Brazil (Bacen). Based on the results of the regression of Panel data on fixed effects, we found evidence that there is a statistically positive relationship between the market risk premium and the interest rate risk premiums. The regression betas showed that the interest rate risk premium is not sensitive when considering the full sample of the G20 countries but is sensitive in the BRICS sample.

Os resultados evidenciam o estudo das figuras geométricas com nuances de teoria dos conjuntos, sobretudo pela linguagem; com noções e princípios representativos do MMM como a correspondência biunívoca, a precisão da linguagem e a justificativa de propriedades. Contudo, embora a iniciação à Geometria por meio de uma abordagem topológica tenha sido uma das propostas importantes da Matemática Moderna para os primeiros anos escolares, esta perspectiva não parece ter repercutido. A Geometria euclidiana estudada com atividades de construção com régua, compasso, transferidor, o recurso aos materiais didáticos ou manipuláveis – planificações, entre outros – transformou o modo como a Geometria era ensinada/aprendida.
Humanities Fiction: Translation and ‘Transplanetarity’ in Ted Chiang’s “The Story of Your Life” and Denis Villeneuve’s Arrival
Authors: Nicol Bran
Published: June 2019

One of the more interesting science fiction movies of recent years, at least to Humanities academics, is Denis Villeneuve’s 2016 alien-invasion movie, Arrival. It is a film which not only features a Professor of Linguistics as its heroine, but the plot of which is organised around the critical global importance of a multi-million dollar translation project. This essay compares the film with the original novella upon which it was based – Ted Chiang’s “Story of Your Life” (1998) – to examine the role translation plays in both, with the aim of placing this in the context of the crisis in the Humanities which has marked universities over the last few years, and can be linked to a more general crisis in liberal values. While founded upon a time-honoured science fiction scenario the movie also clearly articulates the sense of global peril which is typical of much of the cultural production of our current times, manifested in fears about ecological catastrophe, terrorist attacks, and the anthropocene, etc. Another of its crisis-points is also ‘very 2016’: its ability to use science fiction tropes to express an anxiety about how liberal values are in danger of being overtaken by a self-interested, forceful, intolerant kind of politics. Arrival is as much a work of ‘hu-fi’ as it is ‘sci-fi’, that is, ‘Humanities fiction’, a film which uses Chiang’s original novella to convey a message about the restorative potential of ‘Humanities values’ in the face of a new global threat.

The aim of this study was to determine the pathological, mycological and molecular findings in turkey poults with different immunological status experimentally infected with Aspergillus fumigatus. The investigation was carried out 1, 3, 7, 14 and 21 days after intratracheal inoculation of 5.056×107 spores of A. fumigatus to 14-day-old turkey poults in group G-1, as well as to turkey poults in group G-2 which were treated prior to infection with dexamethasone. A. fumigatus was isolated on day 1 p.i. in both groups, but the number of positive samples was bigger in group G-1. A. fumigatus was isolated from the respiratory organs of group G-1as early as on day 1 and 3 p.i. in 4 out of 12 examined specimens (33%). On day 7 p.i. A. fumigatus was possible to isolate from the respiratory organs of 50% of infected birds, on day 14 in 83.33% and on day 21 p.i. A. fumigatus was isolated in 6 out of 6 sacrificed turkey poults (100%). In dexamethasone-treated group A. fumigatus isolates from the respiratory organs on day 1 and 3 p.i. were same as in group G-1, whereas on days 7 and 14 p.i. the number of turkey poults positive to A. fumigatus increased in comparison with the untreated G-1 group. The histopathological lesions in turkey poults treated with dexamethasone developed earlier, were more intensive and extensive. The mycological and nested PCR results revealed a higher number of samples positive for the presence of A. fumigatus DNA in the group G-2, pretreated with dexamethasone.

Background: Written health educational materials are an integral part of the treatment process. Because of the constantly increasing gestational diabetes mellitus (GDM) global rate, pregnant women require accessible, easy-to-understand and evidence-based medical information about this pregnancy complication.

Aim: To adapt and elaborate printed educational materials on GDM and to evaluate the usefulness of the produced training materials and pregnant women’s satisfaction.

Materials and methods: The present study implemented a methodological approach covering three phases: (1) systematic literature review; (2) compilation of printed educational materials for pregnant women with GDM; (3) evaluation of the usefulness and satisfaction with the produced educational materials through a focus group consisting of pregnant women. A seven-item self-administered feedback questionnaire was adopted for evaluation of patient satisfaction after the use of educational materials.

Results: An educational manual was developed in compliance with the main requirements for effectiveness of educational materials referring to content, structure, language, layout and illustrations. The usefulness of the educational manual and patient satisfaction were evaluated by a sample group of 20 women with GDM. Approximately 95% agreed or strongly agreed that the information in the educational manual was useful. The patients’ assessment of the understanding and readability of the written materials showed a satisfaction rate of 85%. The overall assessment for the educational materials was very high - excellent (65%), very good (30%) and good (5%).

Conclusion: The provision of educational materials on GDM can enhance pregnant women’s health literacy as well as their responsibility, motivation and attitude to their personal health.

Published: June 2019

Background: Lycium barbarum has gained immense popularity over the past decade because of its antioxidant properties. There are many reports of observed health benefits of juice consumption, including prophylaxis in neoplastic disease and treatment of tumors.

Materials and methods: In this study, we isolated three fractions of Lycium barbarum fruits – total water, pectin-free and polysaccharide, and determined their antioxidant activity by ORAC and HORAC assays. We investigated the antiproliferative effects of Lycium barbarum’s pectin-free and polysaccharide fraction on three different breast cell lines - MCF-10A (non-tumorigenic epithelial breast cell line), MCF-7 (breast cancer cell line, estrogen, progesterone receptors +, HER2-), and MDA-MB-231 (breast cancer cell line, triple negative), by the MTT dye reduction assay.

Results: The Lycium barbarum’s pectin-free fraction showed concentration-dependent growth inhibition on the three cell lines, moreover, on cancer cells (MCF- 7 and MDA-MB-231) it was significantly more pronounced. The polysaccharide fraction showed negligible activity on the three cell lines, only the highest concentration (1000 μg/mL), suppressed the proliferation of MCF-7 cells. The combination of pectin-free and polysaccharide fraction on MCF-7 did not show the expected synergistic effect.

Conclusion: We found a relative correlation between the polyphenolic content of the extracts and the observed effects. The pectin-free extract had the highest content of polyphenols with the best antioxidant and antineoplastic activity against breast cancer cells. Addition of polysaccharide to the pectin-free fraction contributes to its pharmacological activity.

Background: Stress associated with learning of a psychomotor task can influence the trainees learning ability. Surgical simulation is a validated training milieu designed to replicate real-life situations, prevent biases and provide objective metrics. However, the complexity of stress mechanisms and the absence of a reliable detection method make stress estimation difficult to quantify and to interpret.

Aim: a) To assess the feasibility of a new watch-sized device to noninvasively measure stress parameters in novices during a simulation task and b) to compare its derived cardiac stress parameters to those of an ambulatory Holter monitor.

Materials and methods: Twenty-one novices were trained on a basic skills module. During base line, exercise, and recovery phases, all subjects wore a wearable device and data regarding blood volume pressure, heart rate, inter beat interval, electrodermal activity, and skin temperature were recorded. Additionally, Holter Monitoring was used to concomitantly capture heart rate, R-R intervals and heart rate variability. Before and after each experiment, all subjects completed the short, six-item STAI scale.

Results: Data analysis showed: a) when compared to STAI, electrodermal activity exhibited the best correlation, sensitivity and specificity and b) the device derived cardiac parameters highly correlated with the reciprocal Holter values during all experiment phases.

Conclusion: This wearable device is an easy to use and well accepted by the participants noninvasive tool, which can provide accurate stress estimation in our simulation setting. Additionally, it can replicate Holter derived stress related heart parameters, thus eliminating the need to wear a rather cumbersome device.
The Main Characteristics of the Urban Climate in Relation to the Built Space Evolution in Bucharest, Romania
Authors: Ilea Raul-Gabriel , Manea Cosmina-Andreea , Antonescu Marina-Aurelia
Published: June 2019

The urban climate is a specific type of topoclimate characteristic to big cities, like Bucharest, which is formed due to the horizontal and vertical expansion of the space, the nature of the materials used for constructions, the pollution, and other side effects of the socio-economic activities. The main objective of this study is the analysis of the variability of four main meteorological elements (air temperature, atmospheric precipitation, relative air humidity, duration of sunshine) in Bucharest and its neighboring area, in relation to the built space evolution. In the last decades, Bucharest has been experiencing an exceptional development, materialized both by territorial expansion, as well as structural-functional and architectural-urbanistic transformations. The fact that the population of the city is increasing, correlated with the expansion of the built space area, suggests the intensity of the urban sprawl phenomena. This has numerous side effects, among which is the creation of a specific topoclimate, different from the one in the periphery. As an example, the results of the meteorological analysis showed that the air temperature is higher inside the city, at the Filaret station, with 0.1ºC, than at the periphery (Baneasa station) and the periurban area (Afumati station).
Application of Geographic Information Systems for Flood Risk Analysis: A Case Study from Accra Metropolitan Area

Published: June 2019

The main objective of the study was to identify high flood risk zones in AMA. The study also used questionnaires to assess local knowledge on what accounts for the high flood risk in their community. Spatial analysis techniques were used to model flood risk based on the following contributory factors; land cover, soil, drainage density, topography and proximity to rivers. The results show that high flood risk areas covered 46.3km2(20%), moderate risk area, 72.9km2(31.6%), low risk area 41.5km2(18%) and very low risk areas, about 6.7km2(2.9%). The high flood risk zones were low-lying areas below 50 meters above sea level and closely associated with poor drainage systems. People perceived not just low-lying areas as a paramount reason accounting for flooding but also very bad waste disposal habit of the public. These offsets the efforts of waste management companies to keep drains free of refuse.
