Mask-Based Approach in Phasing and Restoring of Single-Particle Diffraction Data
Authors: Lunin V.Y. , Lunina N.L. , Petrova T.E.
Published: March 2020

The development of experimental techniques, in particular the emergence of the X-ray free-electron lasers, allows one to register the scattering from an isolated particle and, thereby, opens a door to the study of a fine three-dimensional structure of non-crystalline biological objects by X-ray diffraction methods. The possibility to measure non-Bragg reflections makes experimental data mutually dependent and essentially simplifies the structure solution. The sampling of experimental scattering data to a sufficiently fine grid makes the structure determination equivalent to phasing of structure factor magnitudes for a 'virtual' crystal with extremely large solvent content. This makes density modification phasing methods especially powerful supposing the object envelope is known. At the same time, such methods may be sensitive to the accuracy of the predefined envelope and completeness of experimental data and may suffer from non-uniqueness of the solution of the phase problem. The mask-based approach is a preliminary phasing method that performs random search for connected object envelopes possessing of the structure factor magnitudes close to the values observed in X-ray experiment. The alignment and averaging of the phase sets corresponding to selected putative envelopes produce an approximate solution of the phase problem. Beside the estimation of unknown phase values this approach allows one to estimate the values of structure factor magnitudes lost in the experiment, e.g. those corresponding to beam-stop shade zone or to oversaturated reflections.

Published: March 2020

Gas turbines are actively used as a part of combined-cycle power units having less impact on the environ-ment than installations operating on other types of fuel. However, their emissions contain harmful carbon compounds and nitrogen oxides. Some research studies considered the effect of emissions upon changes in the coefficient of excess air. At the same time, no attention was paid to the influence of other operational parameters and technological limitations associated with the safe operation of combined-cycle CCGT equipment, and no assessment was made of the impact of climatic factors on environmental indicators. Thus, it is important to conduct separate studies to assess the influence of regime and climatic factors on the stability of the combustion process in the combustion chamber of a gas turbine, on the environmental performance of the installation and the compliance of these indicators with the standards. The research used data from the control system archive, and a simulation model was developed in the SimInTech environment. The following assumptions are made in the model: the fuel composition does not change and it enters the single combustion zone without separation into the pilot and central zones of the combustion chamber. The methodology for calculating emissions is reduced to dividing their volume into NO and NO2 due to the transformation of nitrogen oxides in the air. Subsequently, the values of the total concentration are recalculated to a single NOx value. A simulation model for calculating emissions has been obtained. The effect of excess air on nitrogen oxide emissions considering the technological zones of gas turbines of outdoor air temperature (To.a) from –20 to +30 оС and the power from 48 to 110 MW has been assessed. It has been shown that near the nominal load the maximum NOx emission are observed. In general, the results obtained indicate that the requirements for NOx emission standards are met in the entire operating range of gas turbine load changes. However, the reserve of a possible deviation of emissions to a critical level is only 10 %. The verification of the developed model is based on operational trends. The recommendations on operational management have been formulated for power unit operators in order to maintain an ac-ceptable level of NOx emissions.

Published: March 2020

Earlier, we obtained a solution to the heat transfer problem in multi-threaded multi-stage heat-exchanging units with one-component heat carriers. However, in the energy, food, and petrochemical industries, often heat and mass transfer processes involve coolants consisting of components whose heat and physical properties differ significantly. For carrying out heat engineering calculations with such coolants, averaging of the indicated properties of the components is usually performed. However, in a number of industrial technologies based on distinguishing thermo-physical properties, in particular, differences in the boiling temperature of the components, processes for their separation by distillation are used. In this case, when calculating heat and mass transfer processes to obtain pure components with acceptable impurities, it is necessary to take into account the difference in their thermo-physical properties precisely. The development of calculating methods for the systems of multi-threaded multi-stage heat transfer processes with multi-component coolants to analyze the efficiency of their separation is a topical issue facing the energy sector and related industries. To study and simulate heat and mass transfer systems, the equations of mass and energy balances and linear algebra methods of are used. Within the framework of the matrix approach, for the case of using a mixture of components with different boiling points as heat transfer agents, a heat and mass transfer process model has been obtained. The model allows evaluating the degree of separation of components and the quality of the finished product by the content of impurities in it for various methods of organizing the process. The solutions of the model equations have been obtained and analyzed. The results can be used to increase the efficiency of resource and energy-saving technologies in solving problems of the optimal distribution of temperatures at the system stages due to recirculation of the selected components and to obtain pure components with an acceptable content of impurities in the energy, chemical and food industries.
As leis sobre o exílio no 'Código Teodosiano'
Authors: Silva Érica Cristhyane Morais da
Published: March 2020

O exílio sempre foi uma forma de punição adotada pelos romanos antigos. Na República e no contexto do Principado são vários os casos de banimentos de senadores. Na Antiguidade Tardia, quase não temos notícias de casos de exílio senatorial presentes na historiografia especializada. Os exílios mais evidentes, mais explorados e estudados, neste contexto, são os casos de banimento episcopal, em especial, durante o governo de Constâncio II (337‑361). Não obstante, os exílios senatoriais continuaram a ocorrer mesmo no contexto da Antiguidade Tardia, embora estes não tenham sido tema de estudo dos historiadores. No Código Teodosiano, não encontramos evidências precisas sobre exílios direcionados a senadores, excetuando o estatuto 14, 10, 3, sobre vestimentas militares utilizadas inapropriadamente, que menciona especificamente o uso de trajes militares por senadores, que é proibido por este estatuto. Não obstante, mesmo com esparsa evidência, neste documento, sob o caso senatorial, nos dedicaremos no espaço desse artigo, à reflexão acerca dos exílios previstos no Código Teodosiano, de modo a compreender os exílios senatoriais como parte do fenômeno do banimento na Antiguidade Tardia.

The article highlighted the advantage of information systems in front of centralized systems in terms of ensuring the security of network infrastructure, data transmitted, and procedures used in the software environment of the complex. It was pointed out the technical simplicity of the methods of expansion of information systems and, accordingly, their scalability. A multilevel energy balance scheme and computing resources of the information system infrastructure, based on the optimization of the task graph, have been developed. The methods of estimating the optimization of the graph of tasks, which are based on the indicators of the normalized graph normalized distribution of energy, are determined. The results of mathematical modeling in comparison with statistical data for such methods of working with task graphs as calculations by hierarchical structure, graph split algorithms, methods based on algebraic theory of graphs, structuring of "Diamond Dags" type. The analysis was conducted for such types of distribution as uniform distribution, binomial distribution, geometric distribution. The results of the comparison point to a sufficiently upstart prediction accuracy at the level of mathematical modeling. In most cases, the value of the maximum deviation, presented as a relative error, between simulation results and statistical data remains within 10%, which shows the adequacy of the simulation. Nevertheless, for the four pairs of functions of the length of the normalized graph and the normalized energy distribution, the maximum deviation is greater than 10%, indicating the need for a revision of the model and further statistical studies. It is proposed to use in organizing the protection of resources of the information system of clusterization methods, which allow to construct a transparent scheme of functioning of the complex and to construct monitoring algorithms.

The conceptual basements of constructing an effective encoding method within the bit rate control module of video traffic in the video data processing system at the source level are considered. The essence of using the proposed method in the course of the video stream bit rate controlling disclosed, namely, the principles of constructing the fragment of the frame code representation and approaches for determining the structural units of the individual video frame within which the control is performed. The method focuses on processing the bit representation of the DCT transformants, and at his processing stage transformant was considered as a structural component of the video stream frame at which the encoding is performed. At the same time, to ensure the video traffic bit rate controlling flexibility, decomposition is performed with respect to each of the transformants to the level of the plurality of bit planes. It is argued that the proposed approach is potentially capable to reducing the video stream bit rate in the worst conditions, that is, when component coding is performed. In addition, this principle of video stream fragmen code representation forming allows to control the level of error that can be made in the bit rate control process. However, in conditions where the bit representation of the transformant is encoded, the method is able to provide higher compression rates as a result of the fact that the values of the detection probability of binary series lengths and the values of detected lengths within the bit plane will be greater than in the case of component coding. This is explained by the structural features of the distribution of binary elements within each of the bit planes, which together form the transformer DCT. In particular, highfrequency transformer regions are most often formed by chains of zero elements. The solutions proposed in the development of the encoding method are able to provide sufficient flexibility to control the bit rate of the video stream, as well as the ability to quickly change the bit rate in a wide range of values.

Authors: Forseeva I.V.
Published: March 2020

The article presents the experience and results of the work of the compensatory type Kindergarten No. 7 teachers with children with autism spectrum disorders on the use of art-pedagogical technologies in practice. 97 preschoolers with disabilities are brought up in this Kindergarten, and 15 people have autism spectrum disorders. All kindergarten preschool children with autism spectrum disorders are integrated into groups of compensating orientation for children with severe speech disorders, taking into account age characteristics. Education and training of preschool children in this category is complicated by violations of their social interaction, scattered attention, backwardness of large and small motor skills, increased excitability and exhaustion, impulsivity and short temper. They do not know how to obey group rules for a long time, listen to and follow instructions, bring the work started to the end, and achieve a certain result. In working with preschoolers with autism spectrum disorders, teachers see prospects for correcting and compensating for violations in the development of artistic and creative activities. The tasks that are solved in an educational organization using methods of artistic and creative habilitation are to develop the child’s personality; develop and correct emotional and volitional processes, reduce fears through isotherapy; create conditions for free experimentation with artistic materials and tools; create an emotional atmosphere that will engage children with autism spectrum disorders in artistic activities. Teachers in their work rely on scientific theories that confirm the validity of the practice of isotherapy, on the results of scientific and applied research in this area, as a result of artistic and creative habilitation, contact was established with every child with autism spectrum disorders (100%). Children have a desire to engage in artistic and creative activities (100%), many began to respond adequately emotionally in various situations of interaction with adults and peers (65%), show empathy for other children (40%), decreased anxiety and fears in new situations of interaction.

Constraining Properties of Sedimentary Strata Using Receiver Functions: An Example from the Atlantic Coastal Plain of the Southeastern United States
Authors: Cunningham Erin , Lekic Vedran
Published: March 2020

Thickness and seismic velocities of sedimentary sequences strongly affect their response during earthquakes, which can prolong and amplify ground motions. We characterize shallow structure of Atlantic Coastal Plain (ACP) sediments using a passive-seismic approach based on high-frequency P-to-S receiver functions. We map the site-specific fundamental frequency for 64 USArray Transportable Array stations and confirm that the method yields results similar to those from traditional spectral ratio techniques, with fundamental frequencies between 0.1 and 1 Hz. In addition, using sediment S-wave reverberations and P-to-S phase arrival times measured directly from the receiver functions, we invert for average S- and P-wave velocity profiles of the ACP sedimentary strata. We find that VS increases with depth following a power-law relationship (VS∝z) whereas the increase of VP with depth is more difficult to constrain using converted wave methods; therefore, we choose to use the Brocher (2005) relationship to obtain VP through a VP/VS relationship. Finally, we use the variation of measured S-reverberation amplitudes with depth to validate these velocity profiles. These results have implications for seismic shaking across the ACP, which covers large portions of the eastern United States.
A Referenced Empirical Ground-Motion Model for Arias Intensity and Cumulative Absolute Velocity Based on the NGA-East Database
Authors: Farhadi Ali , Pezeshk Shahram
Published: March 2020

In this study, we use the referenced empirical method of Atkinson (2008) to develop a ground-motion model (GMM) for estimating Arias intensity (IA) and cumulative absolute velocity (CAV) for the central and eastern North America. We use Campbell and Bozorgnia (2019) as the reference model. To achieve the objectives of this study, we begin with computing the geometric mean of the IA and CAV from the two as-recorded horizontal components of the motion for the recording motions in the Next Generation Attenuation-East strong-motion database. Then, we calculate the residuals of Campbell and Bozorgnia (2019) reference GMM for both IA and CAV. Next, we use the mixed-effect regression approach introduced by Abrahamson and Youngs (1992) to define adjustment factors to the Campbell and Bozorgnia (2019) model. Finally, we evaluate the proposed referenced empirical model by performing a set of residual analyses and comparing model predictions with observed data. The proposed model shows no apparent residual trend for magnitude or distance and implicitly accounts for the site term using the site factors proposed by Campbell and Bozorgnia (2019) model. The valid distance and magnitude range of the proposed model is the same as the selected reference model. In addition, we consider our new model to be applicable for time-averaged shear-wave velocity in the upper 30 m (VS30) between 150 and 2000  m/s.
Development Issues and Potential Safeguards: A Study on Bangladesh Stock Market

The capital market is a very prankish place that holds two types of risk. One is the risk at the efficiency level of the market that refers to the structural weakness. And the other one is the man-made danger that indicates the stakeholders’ irrational behaviors some examples of which are manipulation, gambling, speculation, rumor and so on. Out of the two, the structural weakness is a sensitive issue of the market, and it can be abated at a great extend when the market is properly structured. Here, the author has mentioned five shields which are termed as the “Financial Safeguards” symbolically. Those are adapting Corporate Governance, introducing Financial Reporting Act, making stock market tribunal, exploring product diversification and enhancing the investors’ knowledge. The complete implementation of these safeguards is absent in Bangladeshi market though they leave a little impact. This article examines those points and how they can be effective rooting the existing problems out from the market.

Published: March 2020

Human behavior in the sphere of life in general and in the area of job, in particular, depends on both internal and external factors. There are many well-accepted academic theories in regard to internal factors that affect job environment of the employees which eventually lead to their satisfaction or dissatisfaction. The external factors have not got such attention because these are country- specific and culture-specific phenomenon. Each country has its uniqueness which forms unique characteristic within her habitants. These country characteristics depend on various factors, and the fundamentals are those that are apparently beyond the immediate control of their people. History, topography, weather, socio-economic status of the people are few of the prominent factors that affect the job environment of most of the people of any particular country. In this paper, a theoretical evaluation of the effects of such prominent factors has been outlined keeping a farther scope to verify the postulates with real-time data.

¿Los supuestos de la mecánica cuántica contribuirían a entender ciertas desigualdades sistémicas capitalistas? El asunto Piketty
Authors: Congote-Ochoa Bernardo
Published: March 2020

El artículo busca probar la hipótesis de que ciertas desigualdades del crecimiento económico se podrían entender más allá de las características del sistema capitalista mismo. El artículo, primero expone algunos aspectos de las formas de pensar determinista newtoniana y mecánica cuántica. Luego, utiliza herramientas cuánticas propuestas, entre otros, por Hawking y Otro (2010), Morin (1990), Prigogine (1990, 1993, 1997) y Russell (1986), probando su utilidad para comprender desigualdades capitalistas expuestas, entre otros, por Marx y Engels (2000), Marx (1970) y Keynes (1970). Y, al final, intenta desvirtuar algunas propuestas de Piketty (2014) en relación con su crítica al crecimiento desigual. La metodología del artículo es descriptivo-comparada. A manera de hallazgo, el artículo propone que la ausencia de herramientas cuánticas en los análisis y terapias aplicadas para resolver problemas cada vez más complejos, explicaría cierto creciente desprestigio de los economistas contemporáneos en el entorno global.

Authors: G Sharmila , V Praba
Published: March 2020

Cervical lymphadenopathy is a common clinical presentation. Enlarged cervical lymphnodes could be due to variety of causes ranging from simple infectious process to malignant neoplastic conditions. Enlarged salivary glands, thyromegaly are also mimickers for enlarged cervical lymphnodes, hence posing diagnostic challenges clinically.In those cases, FNAC can be used as first line diagnostic test.

Purpose of this study is to utilize the usefulness of FNAC in diagnosis of both pediatric and adult cervical lymphadenopathy and to determine the spectrum of disease distribution among various age group patients in a tertiary care hospital.

This is a retrospective study carried out at IRT Perundurai medical college for aperiod of two years from January 2018 to December 2019. 318 patients with enlarged neck nodes more than6-week duration were registered and aspirated. Aspirated material was used for cytology analysis using Haematoxylin and eosin staining, MGG staining. Special stains such as modified ziehlneelson staining for AFB was also done. Datas were statistically analyzed.

Out of 318 cases of FNAC performed in patients with enlarged cervical nodes,268 cases were found to be adults, the most frequent cause in adults was found to be tuberculous lymphadenitis followed by metastatic carcinomatous deposit and third most common cause was reactive lymphoid hyperplasia, whereas in pediatric patients the most common cause was found to be reactive lymphoid hyperplasia.

:In our study was conducted in a tertiary care hospital, the most common cause of cervical lymphadenopathy in adults was found to be tuberculous lymphadenitis followed by metastatic carcinomatous deposit whereas in case of pediatric cases the most common cause of cervical lymphadenopathy is reactive lymphoid hyperplasia closely followed by tuberculous lymphadenitis. As per WHO –Sustainable development goals-to end TB epidemic in 2030-this study alarms the increasing burden on health sector in fighting against mycobacterium. FNAC is particularly efficacious in our country where mycobacterial infection is endemic. Hence early intervention is mandatory.

Se estudió el efecto de la valencia emocional y los tiempos de exposición en la consolidación de la memoria implícita mediante el uso del paradigma de priming perceptual enmascarado modificado, con reconocimiento de emociones bajo condiciones de consciencia limitada. Se presentaron rostros priming con expresiones emocionales de felicidad, rabia y neutro, en tiempos de exposición de 17ms, 33ms y 83 ms; posteriormente, los sujetos ejecutaron la tarea de memoria implícita, la cual consistía en recordar la emoción del rostro target de la primera tarea. Se encontraron diferencias estadísticamente significativas a nivel de la valencia emocional entre los diferentes tiempos de exposición en la tarea de procesamiento perceptual, en comparación con la tarea de consolidación de la memoria implícita a nivel de los tiempos de reacción. Igualmente, se encontraron diferencias estadísticamente significativas en los tiempos de exposición al comparar la tarea de procesamiento perceptual y la de consolidación de la memoria implícita. Los resultados obtenidos explican que existe una correlación entre las respuestas correctas de esta última tarea y las valencias emocionales, con cada uno de los tres tiempos de exposición. Estos resultados sugieren que las valencias emocionales influyen diferencialmente en las tareas de procesamiento perceptual y consolidación de la memoria implícita.

This cross-sectional study was conducted on 139 residents recruited through the census method. Data were collected usingthe American Board of Internal Medicine Professionalism Questionnaire. The first part of the questionnaire was on residents’ personal characteristics, and the second part containedfifteen items in the three domains of professionalism, namely excellence, honor/integrity, and altruism/respect. The mean scores of the questionnaire and its domains were calculated and their relationships with residents’ personal characteristics were evaluated. The mean scores (± SD) of professionalism and its excellence, honor/integrity, and altruism/respect domains were 4.93 ± 2.4, 5.92 ± 1.85, 4.94 ± 3.39, and 4.35 ± 3.27, respectively (in a range of 0-10). Professionalism had significant relationships only with residents’ specialty and gender. The level of professionalism in residents was low, which requires the attention of educational authorities. Moreover, the mean score of professionalism among residents in surgical specialties was significantly lower than non-surgical specialties. Various factors can be considered in this regard and it cannot be concluded that the lower score means worse professionalbehavior.

Authors: T. J. Bystrova , L.V Tokarskaya
Published: March 2020

This article raises the question of the impossibility of standardized use of augmented reality technologies in the educational process. This approach changes the status of augmented reality and transforms it into a phenomenon of visual culture. The authors represent a hypothetical ratio of physical and augmented realities in educational products for people with autism spectrum disorders (ASD), considering their needs, behavioral patterns and states. The proportion is based on the authors’ advanced research.
Keywords: augmented reality, visual culture, education, educational product, needs, autism spectrum disorders.

Published: March 2020

Este é um estudo transversal, quantitativo e qualitativo, e do tipo estudo de caso, realizado em 2016, que tem como objetivo verificar a ocorrência de violência obstétrica entre as mulheres atendidas pelo Programa Mulheres Mil em um município no interior de Minas Gerais. Para as variáveis quantitativas, foi realizada a análise descritiva dos dados e para a análise qualitativa utilizou-se a Análise de Conteúdo Temática a partir de Bardin. A pesquisa teve a participação de 20 mulheres e, a faixa etária mais prevalente foi de 36 a 40 anos (40%), 40% das mulheres declararam viver uma união estável e 35% afirmaram possuir ensino médio completo. Verificou-se falta de informações que deveriam ser prestadas às gestantes. A cesariana vem sendo usada como uma prática de programação da mãe e, além de não saberem as informações básicas sobre obstetrícia humanizada, desconheciam seus direitos, como o de ter um acompanhante. Assim, a forma mais eficaz de combate à violência obstétrica é despertando a população para a existência dessa realidade.

Trata-se de estudo transversal de base populacional com amostra de 1489 mulheres residentes em Uberaba, Minas Gerais, m 2014. As mulheres mais jovens (18-40 anos) foram frequentes no grupo insatisfeitas com a saúde (p<0,001), assim como aquelas com mais anos de escolaridade (9 anos ou mais) (p=0,002) e as insatisfeitas com a renda (p<0,001). As mulheres entre 41-59 anos (p<0,001), com maior escolaridade (p<0,001) e com renda insuficiente (p<0,001) avaliaram a qualidade de vida como ruim com mais frequência do que as mulheres em outros grupos (p<0,001).

Background: Few studies have evaluated intentions to undergo periodic sexually transmitted infection (STI) and HIV testing among female sex workers (FSW) in Sub-Saharan Africa. We aimed to assess intention to seek periodic syphilis and HIV testing among FSW in Uganda. Methods: Between July and October 2018, we conducted a cross-sectional study among 441 FSW. Participants were recruited through peer referrals. Self-reported data on intention to take a syphilis test in the next 3 months and an HIV test in next 6 months were obtained using an interviewer-administered questionnaire. We used constructs of the Integrated Change Model to assess intentions, attitudes, norms, social influences and self-efficacy towards 3-monthly syphilis and 6-monthly HIV testing. Predictors of intention to seek testing were estimated using linear regression.Results: A total of 441 FSW were included in the analysis, and the median age was 26 years (interquartile range [IQR] 23–30). Most (66.9%) reported high intention to take an HIV test in the next 6 months, and 51.9% showed high intention to take a serological syphilis test in the next 3 months. In multivariable analysis, never testing for HIV was associated with low intention of testing (β=-0.15, p=0.001). Factors significantly associated with high intentions to test for HIV in the next 6 months were perceived influence of significant others (β=0.08, p=0.03), high self-efficacy (β=0.26, p=0.001) and high attitude scores (β=0.45, p=0.001). Similarly, high attitude (β=0.30, P=0.001) and descriptive norms (β=0.32, P=0.001) were associated with high intentions to test for syphilis in the next three months. Conclusion: These results suggest public health programs promoting routine HIV and syphilis testing should consider factors such as attitudes, descriptive norms, social influences, self-efficacy and past behaviours which inform intention to undergo STI testing.
Clients Input Improves Satisfaction on HIV and AIDS Program

Published: March 2020

Background: AIDS Vancouver is a donor funded non-profit organization that supports people living with HIV and AIDS (PLWHA). Like many health providers there is need to look for effective less costly methods of not only delivering services but improve the quality and coverage as well. Literature indicates that the participation of clients is an effective low-cost method of improving service. PLWHA are reluctant to participate in client input initiatives because of negative reactions in society to their condition. Innovative methods to engage clients need to be utilized.Methods: An initial survey was conducted to determine the base satisfaction level. The survey also indicated areas for improvement. Consultation sessions were conducted with clients, volunteers and staff on which issues to tackle and how. This process has been repeated for three consecutive years. Appreciative Inquiry (AI)and Social Constructivism (SC) theories were selected as guidelines on client engagement. AI was selected to encourage participants to use the strengths and resources around them to improve the program. Social Constructivism was selected for its ability to combine individual perspectives in constructing meaning that is acceptable to all participants.Results: Annual surveys have become a useful tool to determine the client satisfaction level on the program. They have also highlighted the dynamic issues related to supporting our clients. The follow-up consultation sessions have generated 41 proposals of which 26 have been implemented successfully. Client satisfaction is up, client participation in running the program continues to grow. The cost implications are minimal, yet the benefits are significant. Client participation raised program satisfaction level by 16 percentage points after one year and has maintained the satisfaction level high in two consecutive years.Conclusions: Client participation was essential in improving the satisfaction level of the program. It was important to create the space for clients to participate and also build trust with clients. Clients have a lot of knowledge about their conditions and provide valuable input. Their contribution is mainly on social aspects rather than technical aspects. These social aspects are essential in improving the client experience and need to be included in improvement initiatives.
