Published: June 2020

Работа посвящена оценке потери кинетической энергии потока газа на краях активных дуг осевых малорасходных турбин, имеющих в своем составе сопловые аппараты с углами установки сопел менее 9 и рабочими колесами с большим относительным шагом рабочих лопаток. Представлены результаты экспериментальных исследований ступеней исследованных малорасходных турбин со средним диаметром соплового аппарата 250 мм в диапазоне варьирования отношения давления перед соплами соплового аппарата к давлению за рабочим колесом от 2.0 до 5.0, частоты вращения ротора от 0 до 14000 об/мин. Представлены результаты исследований потерь мощности и потерь энергии на вентиляцию и трение дисков рабочих колес ступеней исследованных турбин с различными величинами отношения давления перед соплами соплового аппарата к давлению за рабочим колесом зависимость коэффициента потерь энергии на краях активных дуг подвода при различной парциальности. Указано, что при малых степенях впуска (степень парциальности низкая) интенсивность увеличения потерь мощности на краях активных дуг исследуемых турбин с уменьшением отношения давления перед соплами соплового аппарата к давлению за рабочим колесом снижается.
The work is devoted to estimating the loss of kinetic energy of the gas flow at the edges of active arcs of axial low-consumption turbines incorporating nozzle apparatuses with nozzle installation angles of less than 9 and working wheels with large relative pitch of the blades. The results of experimental studies of stages of low-consumption turbines with an average nozzle diameter of 250 mm in the range of variation of the ratio of the pressure in front of the nozzles of the nozzle apparatus to the pressure behind the impeller from 2.0 to 5.0, the rotor speed from 0 to 14000 rpm are presented. The results of studies of power losses and energy losses for ventilation and friction of the wheels of the impeller wheels of the investigated turbines with different values of the ratio of the pressure in front of the nozzles of the nozzle apparatus to the pressure behind the impeller are presented dependence of the coefficient of energy loss at the edges of active supply arcs at different partialities. It is indicated that at low inlet degrees (low degree of partialness), the intensity of power loss at the edges of the active arcs of the turbines under study decreases with a decrease in the ratio of pressure in front of the nozzles of the nozzle apparatus to the pressure behind the impeller.

Изложены возможности и особенности использования в Арктической зоне России сети метеорной связи, которую целесообразно применить в целях обеспечения безопасности функционирования объектов транспортной инфраструктуры Северного морского пути, что способствует повышению экономической эффективности в целом всего морского транспортно-технологического процесса, а также для обеспечения безопасности судоходства в указанном регионе с учетом специфики распространения УКВ-радиосигналов и больших расстояний между объектами. Представлена временная диаграмма, характеризующая процесс функционирования радиолинии метеорной связи, соответственно, для оценки прерывистости связи предлагается использовать специальный параметр под названием коэффициент использования радиолинии. Показано, что для обеспечения энергетического контакта необходимой длительности между удаленными ведущими и ведомыми станциями метеорной связи в качестве пассивного ретранслятора может насыщенный метеорный след, способный обеспечить требуемую устойчивую связь, удовлетворяющей заданным требованиям по защите информации и по вероятности ошибочного приема ложных знаков с сохранением целостности сообщений при условии прерывистости энергетических контактов между корреспондентами.
This paper describes the possibilities and features of using the meteor communication network in the Arctic zone of Russia. It is advisable to use this meteor communication network in order to ensure the safety of the transport infrastructure of the Northern sea route. This contributes to the overall economic efficiency of the entire Maritime transport and technological process. Also, it is appropriate to ensure the safety of navigation in the region, taking into account the specifics of the propagation of VHF radio signals and long distances between the objects. A timing diagram characterizing the operation of the meteor radio link is presented, so it is proposed to use a special parameter called the radio link utilization factor to estimate communication discontinuity. It has been shown that a saturated meteor trail can be used as a passive repeater to provide energy contact of the desired duration between the remote leading and trailing meteor communication stations. This is capable to provide the required stable communication that meets the specified data protection requirements. And it is also urgent for the probability of erroneous false signs reception with preservation of messages integrity under condition of energy contacts discontinuity between correspondents.

В эпоху интеллектуальных транспортных систем (ИТС) и технологий, поддерживающих механизмы анализа и передачи видеоинформации, проблема проектирования на основе технологии система на кристалле с распределением площади кристалла между вычислительной и фотоприёмной частями проекта становится важнейшей с позиции системного уровня проектирования. Проблема анализа видеоинформации в целом, кодирования и декодирования изображений с целью своевременной доставки в частности, до сих пор считается сложной и актуальной при синтезе видеосистем на кристалле. В работе предлагается модифицированный маршрут проектирования транспортных видеосистем на кристалле на основе функционала вектора концепции, включающего информационные показатели эффективности видеосистем анализа и передачи видеоинформации. Предложен модифицированный маршрут проектирования интеллектуальных транспортных видеосистем на основе технологии система на кристалле .
In the era of intelligent transport video systems (ITVS) and technologies that support mechanisms for analyzing and transmitting video information, the problem of designing on the basis of technology system on chip and the allocation of chip area between computing and photodetector parts of the project becomes important with the system design level. The problem of analyzing video information in General, and encoding and decoding images for timely delivery in particular, is still considered complex and relevant in the synthesis of video systems on a chip. The paper proposes a modified route for designing transport video systems on a chip based on the functional vector of the concept, which includes information performance indicators of video systems for analysis and transmission of video information. A modified route for designing intelligent transport video systems based on the system n crystal technology is proposed.

Apropiación tecnológica y cuerpos femeninos: el camino del código abierto
Authors: Soria Guzmán Martha Irene 
Published: June 2020

En muchos casos, la apropiación tecnológica se ha asociado al manejo de herramientas o dispositivos que a su vez han sido mediados por corporativos que los usan como mecanismos de control. De igual forma, el sistema heteropatriarcal ha normalizado la dominación del cuerpo femenino a través de ideas sesgadas de lo que significa “ser mujer”.
En ambos casos, los posibles vehículos para la emancipación podrían ser: el conocimiento, la confianza y la capacidad de decisión sobre nuestra tecnología y nuestros cuerpos.
El presente ensayo, propone que la apropiación tecnológica vaya más allá del manejo de una herramienta, ya que es preciso saber cómo fue hecha, conocerla, intervenirla o crear una propia, lo cual, solo será posible con software libre, cuya filosofía de código abierto, compartición y colaboración en beneficio de la comunidad, coinciden con la filosofía hacker y el feminismo.
Tejiendo masculinidades: tres relatos de vida acerca de la construcción social de la masculinidad en sus narrativas sobre el cuerpo y la indumentaria
Authors: Saucedo Rodríguez Jesús Donaldo 
Published: June 2020

Los estudios de género han puesto en la mira del análisis social los procesos socioculturales que atraviesan la dimensión simbólica y práctica del género a través del cuerpo. Por ello, se propuso analizar el proceso de construcción de la masculinidad de tres hombres saltillenses con relación a sus narrativas sobre el cuerpo y la indumentaria, a partir de sus relatos de vida y un trabajo visual. El análisis sugiere que la manera en la que estos hombres llevan y adornan su cuerpo cotidianamente narra los procesos de construcción de la masculinidad por los cuales significan su experiencia subjetiva como hombres.

La comunicación como factor del intraemprendimiento: El caso de una Institución de Educación Superior de la Región Centro Occidente de México
Authors: Alcaráz Muñiz Ana Paola , Pastor Pérez María del Pilar 
Published: June 2020

Hasta el momento, el intraemprendimiento, como una actividad llevada a cabo dentro de las organizaciones, ha tenido poca relevancia teórica y empírica fuera del contexto empresarial. El propósito del presente estudio es identificar la influencia de la comunicación en el intraemprendimiento que ejercen los profesores de una institución pública de educación superior (IES). Con el fin de lograr el objetivo se realizaron 12 entrevistas semiestructuradas a docentes de las seis áreas del conocimiento adscritas a la institución. Los resultados obtenidos mediante el análisis del discurso de las entrevistas evidencian la importancia de la comunicación productiva para generar la búsqueda de nuevas oportunidades dentro de las IES, además se describen las acciones de comunicación que realiza la institución para fomentar el intraemprendimiento. A partir de este estudio, se sugiere que las IES deben adoptar una cultura intraemprendedora, a partir de propiciar estructuras organizacionales flexibles que permitan cambiar procesos, entre ellos los comunicativos, donde se fomente el intercambio de conocimiento y se apoyen las investigaciones para crear innovación y transferencia de tecnología.

On the Paradoxical Impact of Blending by Red Clump Giants
Authors: Majaess Daniel J. 
Published: June 2020

Abstract
The impact of blending by red clump giants (RCGs; or relatively metal-rich red horizontal branch stars) is discussed as it relates to RRab and classical Cepheids, and invariably establishing an improved distance scale. An analysis of Magellanic Cloud variables reaffirms that blending with RCGs may advantageously thrust remote extragalactic stars into the range of detectability. Specifically, simulations of Magellanic Cloud RRab and RCG blends partly reproduce bright non-canonical trends readily observed in amplitude–magnitude space (I

versus

). Conversely, the larger magnitude offset between classical Cepheids and RCGs causes the latter’s influence to be challenging to address. The relative invariance of a Wesenheit function’s slope to metallicity (e.g.,

) implies that a deviation from the trend could reveal blending and photometric inaccuracies (e.g., standardization), as blending by RCGs (a proxy of an evolved red stellar demographic) can flatten period-Wesenehit relations owing to the increased impact on less-luminous shorter-period Cepheids. That could partly explain both a shallower inferred Wesenheit function and overestimated H
0 values. A consensus framework to identify and exploit blending is desirable, as presently H
0 estimates from diverse teams are unwittingly leveraged without homogenizing the disparate approaches (e.g., no blending correction to a sizable

Blazar Variability: A Study of Nonstationarity and the Flux–Rms Relation
Authors: Bhattacharyya Joy , Ghosh Ritesh , Chatterjee Ritaban , Das Nabanita 
Published: June 2020

Abstract
We analyze X-ray light curves of the blazars Mrk 421, PKS 2155−304, and 3C 273 using observations by the Soft X-ray Telescope on board AstroSat and archival XMM-Newton data. We use light curves of length 30–90 ks from three to four epochs for all three blazars. We apply the autoregressive integrated moving average model, which indicates the variability is consistent with short memory processes for most of the epochs. We show that the power spectral density (PSDs) of the X-ray variabilities of the individual blazars are consistent within uncertainties across the epochs. This implies that the construction of broadband PSD using light curves from different epochs is accurate. However, using certain properties of the variance of the light curves and its segments, we show that the blazars exhibit hints of nonstationarity beyond that due to their characteristic red-noise nature in some of those observations. We find a linear relationship between the root-mean-squared amplitude of variability at shorter timescales and the mean flux level at longer timescales for light curves of Mrk 421 across epochs separated by decades as well as light curves spanning 5 days and ∼10 yr. The presence of a flux–rms relation over very different timescales may imply that, similar to the X-ray binaries and Seyfert galaxies, longer and shorter timescale variabilities are connected in blazars.

Introduction: Following the recommendation of the Global Leprosy Strategy, Ethiopia targeted to reduce the incidence of new leprosy cases, and the proportion with severe disability (grade 2) from 13.6% in 2016 to < 1% in 2020. This study assessed the clinical profile of new leprosy cases and the sequelae of previously treated ones 20 years after leprosy was eliminated as a public health problem in the country.
Methodology: Hospital based cross sectional study was conducted by reviewing the medical records of all leprosy patients seen at the dermatology clinic of Boru Meda Hospital from August to December 2018.The data were captured using a standard data collection form.
Results: Over the study period, 57 (27.4%) new cases and 151 (72.6%) previously treated cases were seen.The median age was 44 years (interquartile range 32-57). Among the newly diagnosed cases, two were under the age of 15 years , 51 (89.5%) were multibacillary and 34 (59.6%) had grade 2 disability. This included visual impairment in 10 (17.5%) and neurological complications in 44 (77.2%). Of the 151 previously treated cases, 104 (68.9%) presented with disabilities, including 97 (64.2%) with grade 2. Amongst previously treated cases, 130 (86.1%) had neurological complications. In addition, 53 (35.1%) had vision impairment.
Conclusions: This study showed evidence of ongoing leprosy transmission and delayed diagnosis in the country. This calls for operational research to determine the underlying reasons and provide ways forward. At the same time, the high burden of disabilities in previously treated cases should be addressed.

Published: June 2020

ABSTRACT
The purpose of this study was to assess multiple-choice questions used in test-banks accompanying selected nursing textbooks. A random sample of 2913 questions was selected from a convenience sample of 17 test banks. Questions were evaluated on (a) adherence to generally accepted guidelines for writing multiple-choice questions; (b) cognitive level as defined by Bloom's (1961) taxonomy; and (c) distribution of correct answers as A, B, C, or D. The results were 2233 violations of item-writing guidelines, most of which were minor but some were serious. A large number of questions (47.3%) were written at the knowledge level and only 6.5% were written at the analysis level. The correct answers were evenly distributed: C2S ranged from 0.00 to 4.84; chi square value needed to reach .05 probability was 26.30. Faculty are encouraged to evaluate multiple-choice questions from test banks carefully before using them for exams.

Published: June 2020

AbstractOssifying fibromyxoid tumors (OFMTs) are rare musculoskeletal tumors of uncertain malignant potential. Most OFMTs arise from the subcutaneous tissue, skeletal muscles of extremities, trunk, or head-and-neck region. OFMTs are usually benign, but atypical and malignant OFMT have been described with recurrence and distant metastasis. Till date, the etiopathogenesis and exact line of differentiation of OFMT is still doubtful. We are presenting an unusual case of malignant OFMT of the tongue. It is a rare case of malignant OFMT affecting an unusual site.
Ovarian Endometriosis with Borderline Serous Tumor- Association or Coincidence – A Case Report and Review of Literature
Authors: Dayal Seema 
Published: June 2020

AbstractEndometriosis is the presence of endometrial glands outside the endometrium, and ovary is the common site for endometriosis. Endometriosis can also transform into malignant tumors. When endometriosis is present within the tumors, the term endometriosis-derived tumor applies, whereas when endometriosis is recognized adjacent to the tumor, it is called as endometriosis-associated tumor. Borderline serous tumor is surface epithelial ovarian tumor. The endometriosis-associated ovarian malignancies are clear cell adenocarcinoma and endometrioid adenocarcinoma, whereas serous and mucinous are rare malignancies with endometriosis. Here, we are presenting a case report in which endometriosis was associated with borderline serous tumor.

Abstract
Background: The incidence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) is on the rise. Although the clinicopathologic characteristics of NENs have been previously reviewed in the literature, the data published in the Indian literature so far are sparse. This study aims to review the clinicopathological features of GEP-NENs, diagnosed at our institution, and that were classified and graded according to the World Health Organization 2010 classification system. Materials and Methods: One hundred patients with GEP-NENs presenting to our institute from August 2012 to May 2016 were analyzed retrospectively. Demographic data and tumor characteristics were expressed as number, percentage, and mean value. Tumor grade was correlated to metastasis through the Chi-square test. p < 0.05 was considered statistically significant. Results: Of the 100 cases studied, 58 were male and 42 were female. The most common primary site was the pancreas (n = 36), followed by the small intestine (n = 19), esophagus (n = 17), stomach (n = 15), colon (n = 6), rectum (n = 4), and appendix (n = 3). The incidence of neuroendocrine tumor (NET) Grade 1 (NET G1) was higher (n = 40) compared to NET Grade 2 (NET G2) (n = 25) and neuroendocrine carcinoma Grade 3 (NEC G3) (n = 35). Overall in these 100 cases, NET G1 tumors and NET G2 tumors were most common in the pancreas (n = 18/36) and (n = 13/36), respectively. NEC G3 tumors were most common in the esophagus (n = 16/17). The most common site of distant metastasis was the liver (n = 23/26). Conclusion: We elucidated the epidemiological and clinicopathological features of patients presenting to our institute with GEP-NENs.
Impact of Sociodemographic Factors and Nutrition on the Duration of Induction Phase of Chemotherapy in children with Acute lymphoblastic leukemia: A Tertiary Center Experience from North India
Authors: Aggarwal Priyanka , Singh TB , Gupta Vineeta 
Published: June 2020

Abstract
Background: Immunocompromised patients are at increased risk of infections, especially those living in poor hygienic conditions. Aims and Objectives: This study aims to assess the effect of weight, immunization status of the child at the start of treatment along with the socioeconomic status (SES), and demographic parameters, i.e., type of house, sanitary facility (SF), and source of drinking water on the duration of induction phase of chemotherapy (delayed if the patient received chemotherapy for >29 days). Materials and Methods: 110 pediatric acute lymphoblastic leukemia patients aged 1.5–14 years who underwent induction of remission from June 2015 to February 2018 were included. The immunization status and weight of the child were recorded at the start of treatment. SES was assessed using modified Kuppuswami scale and a questionnaire was used to determine various sociodemographic parameters. Results: The patients not immunized as per age (P = 0.000) and having poor demographic parameters, i.e., mud house (P = 0.000), absence of SF (P = 0.013), and nonfiltered drinking water (P = 0.005), had significant delay. The duration of induction phase of chemotherapy was not delayed with poor SES (P = 0.832). Although the duration was delayed in patients with weight ≥10 percentile, it was not statistically significant (P = 0.079). On analyzing the three demographic parameters together as Water-Sanitary Facility-Housing (WaSH) Score (0–4), the duration was also significantly delayed if the patients had WaSH score <2. Conclusion: The duration of induction phase of chemotherapy is delayed with inadequate immunization status and poor hygiene of the child.
