Обоснование. В детском возрасте кардиальная патология представлена преимущественно невоспалительными заболеваниями. В структуре ука-занных заболеваний в последние десятилетия наметилось устойчивое преобладание вегетососудистых дисфункций (ВСД). В подавляющем боль-шинстве случаев при этом развивается их гипотензивный тип. Материалы и методы. Обследованы 89 подростков в возрасте от 11 до 14 лет, страдающих ВСД по гипотензивному типу, среди них 36 подростков, у которых ВСД сочеталась с гиперплазией щитовидной железы 1-й степени (ВСД+ЩЖ), и 53 подростка с ВСД, имеющих в анамнезе указания на перинатальное поражение центральной нервной системы (ППЦНС). Контрольную группу составили 69 здоровых подростков аналогичного воз-раста. Всем обследованным выполнено типирование 15 антигенов группы А и 24 антигена группы В главного комплекса гистосовместимости HLA. Результаты. При определении силы ассоциации типированных антигенов с ВСД+ЩЖ наиболее выраженная связь констатирована у антигена В44, в меньшей степени – антигенов В15 и В5, а также антигена А1. Ассоциация с ППЦНС наиболее выраженной оказалась для антигенов В44 и А29. Достаточно сильной была связь с болезнью антигена В13. В несколько меньшей степени она определялась для антигенов А25 и А19. Досто-верно более частая встречаемость у подростков с ВСД антигена В44 как при сопутствующей гиперплазии щитовидной железы, так и при наличии анамнестических указаний на перенесенное в перинатальном периоде поражение ЦНС свидетельствует о подобном механизме наследования и развития ВСД у подростков. Наличие у ребенка антигена В44 позволяет с высокой долей вероятности прогнозировать возможность развития у него ВСД. Ключевые слова: подростки, вегетососудистая дисфункция, гиперплазия щитовидной железы, антигены. Для цитирования: Мельникова И.Ю., Буряк В.Н.

Exploring social innovation in health in Central America and the Caribbean
Authors: Mothe Josselyn , Vacaflor Luis E. , Castro-Arroyave Diana M. , Cuervo Luis Gabriel , Gore Saravia Nancy
Published: August 2020

Universal health coverage is a public health priority in the Americas. Social innovation in health offers novel solutions to unmet needs, by enabling health care delivery to be more inclusive, affordable, and effective. In 2017, an international collaborative consortium launched an open call for solutions that sought to identify social innovations in health in Central America and the Caribbean. The focus was set on how these solutions can strengthen health care delivery, with emphasis on reducing the impact of neglected transmissible diseases. A crowdsourcing strategy was implemented to identify social innovations in health. These were evaluated by an external panel of experts and practitioners and civil society representing the health and social innovation sectors, based on the appropriateness, innovativeness, and affordability of the solution. The three top-scoring solutions were analyzed through case studies including site visits by a team of investigators. Two key findings emerged from the response to the call: 1) innovative solutions were based on the knowledge and experience of individuals and communities facing adverse situations; 2) this knowledge was shared through health promotion and education, leading to empowerment of the communities. The principal challenges addressed by the solutions were the limited access to quality health care services and failed traditional strategies for vector control. The solutions identified demonstrated how social innovation can strengthen health systems by delivering novel solutions to health needs and articulating communities to enable them to work hand-in-hand with the health system toward universal health.

Kolonialisasi Inggris dan Pengaruhnya Terhadap Masyarakat Tradisional Afrika dalam Novel Things Fall Apart Karya Chinua Achebe
Authors: Hadiyanto -
Published: August 2020

This paper discusses England colonization and its impacts on African tribal culture in African Anglophone novel Things Fall Apart written by Chinua Achebe. The approach used in this research is post-colonial approach by using post-colonial theory to analyze phenomena as well as implication of the colonizer and the colonized relationship. The result of this research indicates that the coming of England colonialists in African Ibo tribe community with their colonization and cultural imperialism is implemented with varied strategies. Those strategies are proven effectively in strengthening England's colonial hegemony in Africa. The England colonialists' imperialism results in horizontal conflict and cultural-social disintegration in African native society; between the   pro-colonial and the anti-colonial. Anti-colonial resistence is shown by most African native society to fight against colonial government arrogance and to resist England imperialism in Africa.
EVALUATION OF GROWTH IN ATLANTIC WHITE SHRIMP LITOPENAEUS SETIFERUS (LINNAEUS, 1767) JUVENILES, USING BIOFLOC AS A FOOD SOURCE IN A CONTROLLED ENVIRONMENT
Authors: Zarza Mez Eduardo Alfredo , Mundo Jonathan Gómez , González Rodrigo Cuervo
Published: August 2020

Biofloc is a new system, little known or applied in Mexico, that offers a high level of sustainability for aquaculture due to its great versatility in terms of nutrient recycling, which enables savings in feed costs and a significant reduction in water exchange. With the objective of evaluating the results of the use of Biofloc in aquaculture, a simulation of an aquaculture facility using Biofloc culture techniques was conducted under controlled laboratory conditions. The use of a combination of shrimp feed and refined sugar as a carbon source enabled the development of floccules, not only enabling the identification of those high-performing organisms and their development in the medium, but also facilitating shrimp capture in order to evaluate growth during each treatment. The treatments were undertaken in two different culture media, one in brackish water and the other in seawater, in which the length and weight of the animals was measured, with their behavior during the bioassay also recorded. It was found that the brackish medium enabled better shrimp development than the seawater medium, provided that the parameters and material in suspension are kept at stable levels, with the former medium providing shrimp an environment rich in food and free of pathogens.

Published: August 2020

Numbers of real-time data (E-BAM) of PM2.5 were collected in the period from Jan 8th 2012 to Jan 1st 2013 at the laboratory of Tropical Ocean University (Sanya, China). The average mass concentration was 19.7 μg/m³. The highest 40.5 μg/m³ in October compared to the lowest 14.1 μg/m³ in July. From a seasonal perspective, the average PM2.5 mass concentration in fall and winter are relatively higher than that in both spring and summer. On the basis of satellite map of fire points and backward trajectories of the air masses, we primarily deduced that the PM2.5 in Sanya may be caused by the biomass burning and industrial pollutants from the area of Pearl River Delta of China and the Indo-China peninsula (e.g. Vietnam, Laos).

Disclosure of information about environmental performance (environmental performance information) to external parties is an important step to show that the company is a good corporate citizenship. Top management realized that the commitment on environmental sustainability can provide a competitive advantage to companies through reduced costs, increased market share, image enhancement and technological leadership. In addition, the role of the management accountant had already increasingly taken into account. The seriousness of top management and company management accountants will be reflected in the establishment of an information system in which to accommodate information about the environment. In practice, most companies do not have adequate systems for measuring and managing environmental costs, or coordinate the collection of environmental data for managerial decisions. This study aims to determine the effect of directly or indirectly from the top management commitment and the role of the management accountant which is mediated by the information system environment on environmental performance.

The move toward a paperless environment has become the driving force behind sustainable development and e-government usage in many public sector institutions. It is equally at the heart of the government campaign to make service delivery in public institutions cost effective, seamless, and efficient. The universities are supposed to be at the front-line of this campaign due to their operations which involves the heavy usage of papers at huge costs. Thus, making it important for university management to provide ICT support in order to promote paperless exchange of information and presentations. It is however, understood recently, that there are issues which surround the low usage of ICT among university managements and ultimately, paperless environment. The purpose of this paper is to discuss the main issues and challenges that hinder the implementation of paperless environment in Nigerian universities. The paper highlights the cyclical order of document generation, document management and document sharing as the process in which a paperless environment can take place within both the academic and the administrative settings in the university. The paper highlights and discussed the challenges hindering the attainment of paperless environment among which are infrastructural gap, inadequate ICT support and attitudinal challenge. It is recommended that for smooth operation of paperless environment, government must show strong political will, bridge the infrastructure gap especially electricity as well as train staff on the path to ICT usage.

Bilingual acoustic voice variation is similarly structured across languages
Authors: Johnson Khia A. , Babel Molly , Fuhrman Robert A.
Published: August 2020

When a bilingual switches languages, do they switch their "voice"? Using a new conversational corpus of speech from early Cantonese-English bilinguals (N = 34), this paper examines the talker-specific acoustic signature of bilingual voices. Following prior work in voice quality variation, 24 filter and source-based acoustic measurements are estimated. The analysis summarizes mean differences for these dimensions, in addition to identifying the underlying structure of each talker's voice across languages with principal components analyses. Canonical redundancy analyses demonstrate that while talkers vary in the degree to which they have the same "voice" across languages, all talkers show strong similarity with themselves.

Blatant dehumanization in the mind's eye: Prevalent even among those who explicitly reject it?
Authors: Petsko Christopher D , Lei Ryan , Kunst Jonas R. , Bruneau Emile , Kteily Nour
Published: August 2020

Research suggests that some people, particularly those on the political right, have a tendency to blatantly dehumanize low-status groups. However, these findings have largely relied on self-report measures, which are notoriously subject to social desirability concerns. To better understand just how widely blatant forms of intergroup dehumanization might extend, the present paper leverages an unobtrusive, data-driven perceptual task to examine how U.S. respondents mentally represent ‘Americans’ vs. ‘Arabs’ (a low-status group in the U.S. that is often explicitly targeted with blatant dehumanization). Data from two reverse-correlation experiments (original N = 108; pre-registered replication N = 336) and seven rating studies (N = 2,301) suggest that U.S. respondents’ mental representations of Arabs are significantly more dehumanizing than their representations of Americans. Furthermore, analyses indicate that this phenomenon is not reducible to a general tendency for our sample to mentally represent Arabs more negatively than Americans. Finally, these findings reveal that blatantly dehumanizing representations of Arabs can be just as prevalent among individuals exhibiting low levels of explicit dehumanization (e.g., liberals) as among individuals exhibiting high levels of explicit dehumanization (e.g., conservatives)—a phenomenon into which exploratory analyses suggest liberals may have only limited awareness. Taken together, these results suggest that blatant dehumanization may be more widespread than previously recognized, and that it can persist even in the minds of those who explicitly reject it.
Do drivers change their manual car-following behaviour after automated car-following?
Authors: Louw Tyron , Goncalves Rafael , Torrao Guilhermina , Radhakrishnan Vishnu , Lyu Wei , Guillen Pablo Puente , Merat Natasha
Published: August 2020

There is evidence that drivers’ behaviour adapts after using different advanced driving assistance systems. For instance, drivers’ headway during car-following reduces after using adaptive cruise control. However, little is known about whether, and how, drivers’ behaviour will change if they experience automated car-following, and how this is affected by engagement in non-driving related tasks (NDRT). The aim of this driving simulator study, conducted as part of the H2020 L3Pilot project, was to address this topic. We also investigated the effect of the presence of a lead vehicle during the resumption of control, on subsequent manual driving behaviour. Thirty-two participants were divided into two experimental groups. During automated car-following, one group was engaged in an NDRT (SAE Level 3), while the other group was free to look around the road environment (SAE Level 2). Both groups were exposed to Long (1.5 s) and Short (.5 s) Time Headway (THW) conditions during automated car-following, and resumed control both with and without a lead vehicle. All post-automation manual drives were compared to a Baseline Manual Drive, which was recorded at the start of the experiment. Drivers in both groups significantly reduced their time headway in all post-automation drives, compared to a Baseline Manual Drive. There was a greater reduction in THW after drivers resumed control in the presence of a lead vehicle, and also after they had experienced a shorter THW during automated car following. However, whether drivers were in L2 or L3 did not appear to influence the change in mean THW. Subjective feedback suggests that drivers appeared not to be aware of the changes to their driving behaviour, but preferred longer THWs in automation. Our results suggest that automated driving systems should adopt longer THWs in car-following situations, since drivers’ behavioural adaptation may lead to adoption of unsafe headways after resumption of control.
Michela de Montaigne’a filozofia człowieka
Authors: Błaszczyk Marek
Published: August 2020

The article aims to show the main aspects of Michel de Montaigne’s philosophy of man, exposing the existential themes presented in it. The paper presents Montaigne’s critique of speculative (academic) philosophy, his reluctance to construct a philosophical system, to describe and explain human life experience as a whole. The article emphasizes that the French philosopher appears as a defender of religious tolerance, a spokesman of dialogue and cultural relativism, and also – considering the existential themes of his work (the problem of loneliness, moral values or art of living) – that he may be considered a pioneer of existential philosophy.

Published: August 2020

The article aims to address the dynamically changing western gaze on the oriental scenery of Casablanca analysed from the perspective of psychoanalytical theory. Crucial to the analysis is the psychoanalytical interpretation of visual culture whose time-space transformations coincide on the border of cultures. The interpretation is particularly focused on the interpersonal relationship between the characters and space-time flashbacks by the symptomatic reading of elements of narrative derived from textual analysis of storytelling. The psychoanalytical framework puts an emphasis on the interpretation of the places where the film’s events occurred in terms of a phantasmatic scene.
Effect of vulcanization time on crosslink density and aging performance of natural rubber composites
Authors: Yilmaz Ece Unur , Dayioglu Ahu Kor , Balaban Seda
Published: August 2020

Natural rubber composites are widely used in the automotive industry because of their improved viscoelastic characteristics that are mostly governed by crosslink density. However, rubber parts suffer deterioration of performance over long service lives. Therefore, optimization of crosslink density and prediction of changes in physico-mechanical properties over time at elevated temperatures is extremely important for the production of safe auto parts. In this work, the effect of vulcanization time on crosslink density and thus the performance and lifetime of natural rubberbased auto parts was investigated. The natural rubber mixture prepared in this context was vulcanized for 3, 5, 10 and 15 minutes at a constant temperature of 160 °C. The crosslink density of each vulcanizite was determined by equilibrium swelling tests and the Flory-Rehner equation. The maximum crosslink density (10.75 × 10-5 mol × cm-3) and the minimum permanent compression set values (10 % at 70 °C and 25 % at 100 °C) were recorded for the sample vulcanized for 10 minutes (v10). Aging behavior of the samples were investigated by stress relaxation tests performed at 85 °C, 100 °C and 120 °C. The service lives of the vulcanizites at different temperatures were predicted by linear Arrhenius fits of degradation times. The sample vulcanized for 10 minutes (v10) was shown to exhibit a service life of 2282 hours at 70 °C in air and the optimum physico-mechanical performance under real operating conditions. The performance and lifetime prediction procedure used in this work could be employed in an early design of rubber components for specific applications.
Investigations on microstructural and mechanical properties of friction stir welded AA 2024-T351
Authors: Kasman Şefika , Ozan Sertan
Published: August 2020

In the present study, AA 2024-T351 plates with a thickness of 6 mm were joined using the friction stir welding technique with three different tool rotational speeds and two different pin profiles. Microstructural features and mechanical properties of welded joints were investigated. The grains in recrystallized regions along the stir zone were observed to be almost with invariable sizes. The grain size was revealed to increase with the increase in tool rotational speed. The average grain size was observed to dramatically increase from 2.3 μm to 5.6 μm for welded joints produced with pentagonal shaped pin. All the welded joints were observed to contain defects; the presence of defects exhibited a negative effect on the tensile properties of the welded joint. Most of the defects were observed to localize at the root region of joints. The joint, welded with the tool rotational speed of 250 rpm using pentagonal shaped pin, exhibited ultimate tensile strength with a value of 365 MPa. The ultimate tensile strength of welded joints was found to be higher with the decrease in the tool rotational speed. The welding efficiency of joints was compared with the ultimate tensile strength of base metal; notably, welding efficiency values between 46 % and 80 % were achieved. Microstructural characterizations revealed that Al2Cu (θ phase), Al2CuMg (S phase), and AlCuFeMnSi, Al7Cu2Fe intermetallic particles were dispersed in the stir zone.
Polícia: etimologia e evolução do conceito
Authors: Afonso João José Rodrigues
Published: August 2020

A palavra polícia tem um longo percurso onomasiológico. Nasce na Antiguidade Clássica greco-romana, com o vocábulo ‘politeia’ dos gregos e ‘politia’ dos romanos, com o significado de governo da Cidade-estado.Na Idade Média, o conceito de polícia evoluiu para significar a boa ordem da sociedade civil, promovida pelo príncipe.Na Idade Moderna, com a emergência das teorias absolutistas do Poder, o conceito de polícia passou a designar toda a atividade do Estado tendente ao bom governo da nação e à ordem pública em geral. O direito policial (jus politiae), entendido como a ciência de governar os homens, constituía o meio através do qual o príncipe atingia o fim eudemonológico do Estado: a felicidade da nação.Com o fim do Antigo Regime e a introdução dos valores liberais, o conceito de polícia tomou um novo rumo, reduzindo-se às dimensões de garante da segurança pública para o exercício dos demais direitos e liberdades. O Estado de direito ajustou-o aos seus princípios dogmáticos. Assim nos chega o sentido atual de polícia.
Penectomia total para tratamento de parafimose crônica em cão: relato de caso
Authors: Braga Filho Cleyson
Published: August 2020

Disorders that affect the reproductive system generate a lot of problems for animals and become a source of concern for tutors. Paraphimosis is one of the most common diseases that affect the genital organ, because it affects dogs of different breeds and ages, and it has a congenital or acquired causes. The disease is characterized by permanent exposure of the canine penis, which does not return to the preputial cavity. However, its evolution may be in stages, such as that the treatment of choice will depend on the severity of the case, and may be both clinical and surgical. Diagnosis is made through visual inspection associated with the tutor's report. In cases of long-term paraphymoses, which are accompanied by tissue involvement, total or partial penile amputation becomes necessary. Therefore, this paper has the objective of report a case of paraphimosis in a dog, which was treated at a private clinic in the city of Crateús-Ce, presenting a story of penile exposure over a period of approximately 10 days. Among the other symptoms that the animal had on physical examination, an extensive fibrous lesion, which a proliferative aspect was observed, affecting the entire mucosa of the glans and external urethral orifice. Giving the definitive diagnosis for paraphimosis, and considering the current stage, the real choice was consisted of total penectomy surgery associated with scrotal urethrostomy, which provided a great recovery and a great patient response.
Experiments in Excreta to Energy
Authors: Chalfin Brenda
Published: August 2020

In the quest for alternatives to energy extraversion and carbon-heavy extraction, transformation of waste to energy is growing worldwide. In Ghana’s working-class city of Ashaiman, an international NGO converts faecal waste into electricity through a massive biodigester. Fed by public toilets, the power is sold back to residents. Touted as an exemplar of sustainable development, Ashaiman’s case demonstrates that when power comes from human waste, the entanglement of energopolitics and biopolitics, but also energopower and necropower – the political uses of death and decay – is undeniable. Premised on such ‘bio-necro collaborations’ and enabled by sustainability science, these interventions activate state monopolies of waste while assimilating bodily excesses of urban dwellers. Marking the intimate exploitations of internal energy frontiers, an ever-tightening circuitry of energy production and political-economic incorporation results.

Cricket is the most famous game but no research work in cricket in the field of biomechanics. The aim of study was to find out the relationship of body segments angles, height of release, angle of release and average speed with deviation of ball. Eight males off spin bowlers has to bowl six legal deliveries. Descriptive statistics was used for describing the data. Pearson product moment correlation was used for the various relationship of the variable to the deviation of the ball. Angle of release (r=0.895**), average velocity (r=0.852), ankle joint left (r=.604), knee joint left (r=0.642), shoulder joint left (r=-.610) and elbow joint left (r=-.694) were significantly correlated to the deviation of the ball.

When choosing the optimal number of sampling intervals of the range of values of a one-dimensional random variable, it is established
that the functional of the square of the probability density is a constant. The values of the constant are independent of the probability density
parameters. The functional dependencies of the studied constant on the coeffi cient of antikurtosis of the distribution law of a random variable
are determined. The analysis of the established dependences for families of lognormal probability densities, Student's distribution laws and
families of probability densities with Gauss distribution is carried out. Based on the results obtained, a generalized model is formed between
the studied constant and the antikurtosis coeffi cient. The generalized model does not depend on the type of probability density, but is
determined by the estimation of the antikurtosis coeffi cient. On this basis, we develop a method for estimating the integral of the square of
the probability density, which involves the following actions. The random variable interval and the antikurtosis coeffi cient are estimated from
the initial sample. At known values of these estimates, the integral of the square of the probability density is calculated. The eff ectiveness
of the proposed method is confi rmed by the results of computational experiments. The conditions of the computational experiment diff er
signifi cantly from the information used in the synthesis of models of the dependence between the studied constant and the antikurtosis
coeffi cient. The conditions of competence of the method of estimating the probability density square integral from the antikurtosis coeffi cient
are established using the proposed models of the dependence of the studied constant on the conditions of the computational experiment.

Published: August 2020

The issues of introducing broadband technologies in civil and special purpose radar systems are considered. The popularity of these technologies for solving a number of practical problems determines the relevance of research related to a detailed analysis of long-range portraits of observed objects at a new qualitative level. The influence of the systematic error of the measuring channel on the reliability of the identification of the geometric shape of the local reflectors of the observation object using the results of broadband radar sounding is studied. The created broadband radar measuring channel with linear frequency modulation of the signal based on the method of generalized heterodyning is described. A technique is proposed for compensating systematic measurement errors for a channel of a given type using calibration spheres. The systematic error in measuring the frequency characteristics of the sphere is estimated, and an error indicator for estimating the frequency characteristics of objects is proposed. The dependence of the statistical indicators of the identification results of the geometric shape of local reflectors on the specified indicator is given. The possibility of identifying the geometric shape of local reflectors of objects by the parameters of their frequency characteristics has been experimentally confirmed. The results can be used to assess the reliability of identifying the geometric shape of local reflectors at the stage of calibration of the measuring channel, as well as to decide on the feasibility of implementing algorithms for identifying the geometric shape of local reflectors on an existing radar.

The issues of using of information and measurement systems based on processing of digital images of microscopic preparations for solving large-scale tasks of automating the diagnosis of acute leukemia are considered. The high density of leukocyte cells in the preparation (hypercellularity) is a feature of microscopic images of bone marrow preparations. It causes the proximity of cells to eachother and their contact with the formation of conglomerates. Measuring of the characteristics of bone marrow cells in such conditions leads to unacceptable errors (more than 50%). The work is devoted to segmentation of contiguous cells in images of bone marrow preparations. A method of cell separation during white blood cell segmentation on images of bone marrow preparations under conditions of hypercellularity of the preparation has been developed. The peculiarity of the proposed method is the use of an approach to segmentation of cell images based on the watershed method with markers. Key stages of the method: the formation of initial markers and builds the lines of watershed, a threshold binarization, shading inside the outline. The parameters of the separation of contiguous cells are determined. The experiment confirmed the effectiveness of the
proposed method. The relative segmentation error was 5 %. The use of the proposed method in information and measurement systems of computer microscopy for automated analysis of bone marrow preparations will help to improve the accuracy of diagnosis of acute leukemia.
