Authors: Nonyenim Solomon Enyidah  , Esther Ijeoma Nonye-Enyidah
Published: February 2022

Background: Puerperal depression is the most common of the mood disorders occurring within the first six weeks postpartum. It affects more than 15% of women across the globe and constitutes a considerable public health problem for the women and their families. It accounts for more than 20% of maternal deaths after child birth. Children of mothers with puerperal depression are likely to suffer severe behavioral problems. It is therefore imperative that factors that contribute to it be identified and considered in their management. Objectives: To determine the prevalence, risk factors and possible predictors of puerperal depression. Methods: women visiting the postnatal clinic six weeks after child birth, who met the study inclusion criteria and consented to the study were interviewed, and screened for depression using a socio-demographic risk factor questionnaire and the Edinburg postnatal depression scale (EPDS). Using the statistical package for social sciences (SPSS) version 23.0, data obtained was analyzed. P-values<0.05 were statistically significant. Results: Four hundred and five (405) women consented to the study and 135, (33.3%) had depression. Among the risk factors isolated, cohabitation, poor emotional and social support, partner violence, mode of delivery, death of children and children’s health challenges were predictive risk factors for puerperal depression. Conclusion: There is a need for urgent overhaul of social systems that favor women before and during pregnancy and after childbirth which will consider these predisposing predictive factors in their management.

Розглядається підвищення достовірності радіолокаційної інформації в багатопозиційних радіолокаційних системах за рахунок використання кооперативного прийому відбитих сигналів. Підвищення достовірності радіолокаційної інформації досягається за рахунок усунення хибних вимірів в багатопозиційній радіолокаційній системі не за рахунок введення додаткових позицій, а за рахунок використання багатопозиційних методів визначення координат повітряних об’єктів. Використання багатопозиційних методів визначення координат повітряних об’єктів передбачає значне зменшення імовірності виникнення хибних вимірів без збільшення кількості позицій. Проведено порівняльний аналіз імовірності виникнення хибного виміру в даній системі при використанні кооперативного прийому відбитих сигналів та без нього.

Stability of Free Available Chlorine Levels in Dilute Sodium Hypochlorite Solutions over a 6-Week Period
Authors: Gow Christopher K , Weinhouse Caren , Johnson Graham O'Brien , Saunders Kim E
Published: February 2022

Animal care and use programs commonly use chlorine and chlorine-based disinfectants to help prevent facility acquired infections in animals. The Department of Comparative Medicine (DCM) at Oregon Health and Science University (OHSU) follows the Centers for Disease Control and Prevention
(CDC) disinfection guidelines for preparing and storing these disinfectants. DCM prepares bottles of dilute solutions of sodium hypochlorite (that is, commercial bleach) daily. In this study, we tested whether dilute bleach solutions, as prepared following the DCM protocol, remained stable
under real-world practice conditions for up to 6 wk. We tested 4 groups of spray bottles filled with 0.5% bleach solutions in these experiments. Specifically, we sprayed 2 groups of bottles daily to mimic use while 2 other groups of bottles were not sprayed. We then measured free available
chlorine (FAC) using 2 methods, spectrophotometry and colorimetric strips. All 4 test groups showed stable maintenance of FAC concentration for the length of the experiment. Mean FAC loss from baseline levels was not significantly different in the group of bottles not sprayed daily (6% for
group 2 at week 5 compared with 7% for Group 4 at week 6). All bottles in Groups 1 and 3 measured by colorimetric strips showed concentrations at or near 5000 mg/L at all weekly time points throughout the experiment. This study shows that 0.5% sodium hypochlorite solutions stored and used
in a standard rodent housing room and sprayed daily will maintain acceptable FAC concentrations for at least 5 to 6 wk, perhaps longer. In addition, we report that colorimetric strips may be a useful and accessible quality control tool for testing freshly prepared solutions at regular intervals.
We conclude that sodium hypochlorite solutions can be prepared on a weekly, biweekly, or monthly basis with no loss in disinfection effectiveness.
The effect of reference conductor location on the ultrashort pulse decomposition in a modal filter on a double-sided printed circuit board.

The location of the reference conductor in a modal filter (MF) on a double-sided printed circuit board (PCB) could affect the decomposition of an acting ultrashort pulse (USP) in the MF. The paper considers two ways of connecting the reference conductors: at the ends of the MF and along the entire MF length. The effect of the filter cross-sectional parameters on the decomposition of USPs is also discussed. The results showed that for two ways of connecting the reference conductors, the difference in per-unit-length mode delays increases with decreasing h and increasing w and s. This, in turn, leads to the increase in the MF attenuation factor. It was revealed that the difference in per-unit-length mode delays is slightly larger in the case of connecting the reference conductors at the end for all values of the parameters. It was also found that if the reference conductors are connected only at the ends, 3 pulses arrive at the MF output (despite the 5 propagating modes in the line). And when the conductors are located along the entire length there are 2 pulses. Accordingly, the decomposition of the input action into 3 pulses allows achieving a larger attenuation of the USP (3.2 times relative to half of the e.m.f.).

Los Mapas de Riesgo son representaciones cartográficas que permiten visualizar la distribución de determinados riesgos en un territorio específico, en este caso, anegamientos producidos por precipitaciones recurrentes. En el presente trabajo se dispone a realizar un Mapa de Riesgo de Inundaciones (MRI) para un sector del norte de la ciudad de Mar del Plata. Varios proyectos de agua y saneamiento para la ciudad de Mar del Plata son desarrollados por Obras Sanitarias Sociedad de Estado (OSSE). Este MRI se acopla al Sistema de Información Geográfica (SIG) de la empresa y servirá para gestionar y planificar futuros proyectos. Este trabajo muestra la primera etapa del proyecto del MRI, el cual tiene como objetivo cartografiar toda la ciudad y ubicar sectores con alto riesgo para poder prevenir potenciales conflictos con la infraestructura de la empresa y posibles consecuencias sobre la población local. También se tuvieron en cuenta los Objetivos de Desarrollo Sostenible de la agenda 2030. Mediante el uso del software libre QGIS se realizó un análisis multivariable, siguiendo los lineamientos legales y de recomendación de organismos locales, nacionales e internacionales. Se obtuvo como resultado un MRI para cuatro sectores del norte de la ciudad, ubicando distintas zonas de riesgo: fueron analizadas y corroboradas in situ y con fotografías históricas georeferenciadas de diversas inundaciones. Dentro de las conclusiones se determinan los próximos pasos a seguir para lograr un MRI de todo el ejido urbano de Mar del Plata y cómo ampliar el proyecto a los sectores periurbanos del partido de General Pueyrredon.
Análisis espacial de evaluación multicriterio con la lógica fuzzy y sistemas de información geográfica aplicado a la vulnerabilidad global en el departamento Pocito (San Juan-Argentina)
Authors: Narváez Luciana Maricel
Published: February 2022

El departamento Pocito, se encuentra afectado por diferentes amenazas de origen natural. Pero el grado de impacto de estos fenómenos peligrosos está en función de la vulnerabilidad, por lo que se considera de suma importancia evaluar su distribución espacial. En este sentido, el objetivo del trabajo consiste en determinar áreas con diferentes niveles de vulnerabilidad global. La metodología empleada consiste en la integración de la evaluación multicriterio y sistemas de información geográfica, donde la conjunción de ambas técnicas es potencialmente valiosa para el análisis espacial. Complementando dicha técnica con el análisis de sensibilidad explícitamente espacial, como uno de los varios soportes para la importante etapa de la validación de los resultados propuesto como modelo decisional. Los resultados obtenidos representan en un mapa las áreas de alta vulnerabilidad que deben ser consideradas para generar políticas de prevención y mitigación del riesgo. Se destacan como áreas vulnerables la zona Este del departamento y próximo al centro de Pocito en donde se encuentran asentamientos precarios. Por otro lado, el análisis de sensibilidad determinó un conjunto de criterios que son significativos y robustos en el modelo de vulnerabilidad. Con esta metodología planteada se pretende avanzar en la reducción de la probabilidad de tomar una decisión incorrecta reduciendo el riesgo de una resolución, mediante la disminución de la incertidumbre de la base de datos y la vacilación de la regla de decisión.

New aspects of eye-head illusions in some British moths
Authors: Craik Clive
Published: February 2022

Photographs are shown of putative false eyes on wings of moths from Scotland. They can be grouped as simple ocelli (small dots and circles); as larger eye-like marks of various sizes, shapes, colours and positions, not recognisably based on any animal group; and as false eyedheads variously
reminiscent of but not species-specific to snake, owl, raptor, primate, cat, rodent, fox and other canids. The most well-known, such as Emperor Moth Saturnia pavonia (Linnaeus, 1758) have large, ostentatious, multi-coloured false eyes but again no definitely recognisable model species.
All this is consistent with the proposal of Janzen, Hallwachs & Burns (2010) that, in this large class of images, a pair of false eyes in a false face or head is the effective anti-predator component, rather than mimicry of species or groups that a predator might regard as harmful to itself.
Examples are also shown and discussed of small blue false eyes, of eye-like marks on hindwings and on thorax rather than on forewings, of false eyes in forewing positions that can differ between individuals of a species, and of crypsis and aposematism that alternate repeatedly as needed within
a single larval instar. A false-eyed head on the forewings of Alder Moth Acronicta alni (Linnaeus, 1767) adds to the well-known defensive images in the two final larval stages of that species. Finally, photographs are shown of putative false eyed-heads on forewings of three species
of Microlepidoptera.

Seroprevalence of hepatitis B in previously undiagnosed patients: A community screening study
Authors: Chahal Daljeet , Lee Joseph GH , Yoshida Eric M , Lowe Chris , Ho Francis , Sum Vivian , Kwan Peter
Published: February 2022

BACKGROUND: Forty percent of hepatitis B carriers have no knowledge of their diagnosis. A prior study in British Columbia suggested high rates of hepatitis B among immigrants. The authors undertook a large-scale screening study to validate these rates. METHODS: Attendees at Asian health fairs without knowledge of their hepatitis B status participated. They completed a questionnaire, and blood was drawn for HBV serologies. Active HBV was defined as HBV surface antigen positive. RESULTS: Of 2,726 patients, 1,704 (62.5%) were female and 1,022 (37.5%) male. Mean age was 62.7 (SD 22.1) years, and mean time of residing in Canada was 27.5 (SD 15.3) years. Most patients originated from China (1,042 patients, 38.2%) and Hong Kong (871, 31.2%). Fifty-six patients tested positive (seroprevalence rate 2.05%, 95% CI 1.52%–2.59%). Most seropositive patients were from China (28 patients, 50.0%). Mean time of residence in Canada for seropositive patients (23.8 [SD 2.1] y) was less than seronegative patients (27.6 [SD 0.3] y) ( p = 0.06). There was a trend towards association of seropositivity with time of residence in Canada (OR 0.98, 95% CI 0.96–1.00, p = 0.09). 8 (14.3%) seropositive patients did not have family doctors, compared with 128 (4.8%) seronegative patients. Lack of a family doctor was strongly associated with seropositivity (OR 3.31, 95% CI 1.32–7.25, χ2 = 10.42, p = 0.001). INTERPRETATION: The authors have shown that high risk immigrant populations may have seroprevalence rates as high as 2,700 per 100,000. Lack of a family physician was associated with seropositivity. These results should be used to design improved outreach programs.
Neurological symptoms and complications of COVID-19. Minireview
Authors: Kulbayeva Z.D. , Klyuyev D.A. , Kaliyeva S.S.
Published: February 2022

Since the first official case of COVID-19 in China in December 2019, researchers have been trying to uncover the mechanism of action of the severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2), which attacks several organs in addition to the lungs and causes circulatory changes that can lead to death not only because of lung failure but also failure of other organs. The aim of this study is to find out the neurological consequences of COVID-19. A systematic review of the literature was concretized by mobilizing the descriptors: “SARS-CoV-2”, “coronavirus infections” and “Neurological Consequences”. Although the effects of SARS-CoV-2 on the lung are exemplary and frightening, the long-term effects on the nervous system may be greater and even more overwhelming, as the regeneration of nerve tissue is difficult and can lead to general disability, as the nervous system coordinates the functions of the entire body. Considered studies point out the presence of various injuries (mild or severe) to central nervous system because of COVID-19 infection. It can be said that the studies all agree on the possibility of existing neurological sequelae and a majority emphasize on the need for further investigation.
Высотная организация равнинных ландшафтов (на примере Центрального Черноземья России)
Authors: Горбунов А.С. , Быковская О.П.
Published: February 2022

Абсолютные и относительные высоты местности выступают важным фактором формирования механизмов организации геосистем не только в горах, но и на равнинах. Они предопределяют различия в показателях морфометрии земной поверхности, интенсивности и направленности ландшафтообразующих процессов, характере ландшафтных рисунков. Основная цель исследования состояла в выявле-нии зависимостей между высотами земной поверхности и ландшафтными метриками на четырех масштабных уровнях. В качестве исследуемой территории было выбрано хорошо изученное в ландшафтном плане Центральное Черноземье России. В ходе работ были подготовлены цифровые модели рельефа и ландшафтные карты, проведен их морфометрический, гидрологический, инсоляционный и текстурный анализы, результаты которых были сведены в базы данных оперативно-территориальных единиц разной размерности. Показатели ландшафтного устройства были разделены на три группы: условие, процесс, результат. В ходе проведенного исследования с помощью регрессионного анализа было установлено, что зависимость параметров расчлененности рельефа от абсолютных высот уменьшается с увеличением масштабного уровня исследования. В то время как зависимость показате-лей, характеризующих ландшафтообразующие процессы и ландшафтные текстуры от относительных высот, растут при уменьшении масштабного уровня исследования. Ранжирование оперативно-территориальных единиц разной размерности по показателям абсолютных и относительных высот позволило выделить единые в морфологическом и динамическом отношении высотно-ландшафтные системы. Также была разработана таксономическая схема высотно-ландшафтных систем, которая включает в себя следующие таксоны: отдел, класс, подкласс, тип, подтип, семейство, род, вид и под-вид.

Following the call to mobilize studies of social-ecological systems and sociotechnical systems, the paper presents the case for studying integrated social-ecological-technological systems (SETS), and dynamic systems that include social, natural and technological (engineering) elements. Using the case study of informal roads in the Baikal region, authors of the article argue that refocusing on SETS creates additional synergies and convergence options to improve the understanding of coupled systems and infrastructure in particular. Historically, transportation infrastructure has contributed to changes in natural and social systems of Northern Eura-sia: Trans-Siberian and Baikal-Amur railroads and Eastern Siberia–Pacific Ocean and Power of Siberia pipe-lines have been the main drivers of social-ecological transitions. At the local scale, informal roads serve as one of the most illustrative and characteristic examples of SETS. The examination of development and trans-formation of the informal roads allows exploring the interactions between socioeconomic processes, ecological dynamics and technological advances. The variety of informal roads reflects the importance of specific social, natural or technological factors in the SETS transformation largely unconditioned by policy and regulations thus providing a unique opportunity to better understand sustainability challenges facing infrastruc-ture-based SETS. Relying on interviews and in-situ observations conducted in 2019 in the Baikal region, the following factors affecting sustainability of informal road SETS were identified: social (identification of ac-tors involved in location, construction, maintenance, use and abandonment of informal roads), technological (road cover, width, frequency and nature of use by different kinds of vehicles), environmental (geomorphology and landscape sensitivity and vulnerability). The sustainability challenges of SETS development and transformations are found in changing mobility practices, social structure and economies of local communities, in-creased occurrences of forest fires and development of erosion and permafrost degradation in local environ-ment and push for development of new technologies of transportation and communication.

Published: February 2022

This article presents the experiment data on pre-sowing treatment of Suaeda salsa Pall. seeds by different concentrations of salts (Na2SO4and NaCl) and soil extract solutions (0 %, 0.6 %, 1.2 %, 1.8 %, 2.8 %, and 3.6 %). The reaction of seedlings and young roots of S. salsa was observed, grown after treatment to salt solutions and soil extracts. In addition, based on the results of the growth of young roots and shoots which are exposed to salt, a comparative description of the growth rates of seedlings and young roots before and after salt stress was made. The results of the experiment showed that S. salsa seeds have a high germination capacity after the elimination of the high level of salt stress and soil extract solution. The significant changes in development rate of S. salsa juvenile root and shoot during and after the salt stress, as well as increasing the germination rate after influence of salt stress were noticed. It was discovered that the growth rates of young roots and shoots of S. salsa are different, salt solutions considerably inhibited the growth of roots of plants seedlings compared to soil extract solution. The salt concentration has a greater effect on roots development. It was found that after the removal of salt stress, the germination rate and regenerative capacity of S. salsa seedlings increased.

The purpose of the article is to analyze the influence of the «female factor» in the family of General Judge Vasyl Kochubey (about 1640–1708), to trace the role of women in supporting the socio-political activity of this family in the elite environment of the Hetmanate. Based on historical sources, contemporary reports and historical intelligence, the author paints a portrait of his wife Lyubov Kochubey and daughters. The methodology of the research his based on a combination of general scientific (analysis, synthesis, generalization) and special-historical methods (historical-structural, historical-anthropological, historical-comparative, prosopographic) with the principles of historicism and objectivity. The application of these methods made it possible to conduct a systematic analysis of the sources, which in their interconnection helped to characterize the activities of the "female" component of the Kochubey family, to analyze the relationships between family members and their environment. Scientific novelty of the work is that for the first time a comprehensive analysis of the situation of women from the family of V. Kochubey has been made, their role in the socio-political and economic sphere was determined. The history of the acquisition and return of Kochubei land holdings during the second half of the 17th–18th centuries is traced from new positions. Conclusions. Research and reproduction of the biography of the Cossack-officer family Kochubey, showed that its representatives were part of the elite stratum of society of the Hetmanate. Successful marital contacts led to the enrichment of the family, the formation of its property potential, provided political and economic support. The members of the family became related to Zhuchenko, Skoropadsky, Obidovsky, Mazepa, Chuykevych, Apostol, Sulima, Zabila, through whose ties vital issues were resolved. During the investigation initiated after V. Kochubey’s denunciation of Hetman I. Mazepa, his wife L. Kochubey supported the family, defending her rights and interests using family ties. It is observed that the «female factor» played a major role in the return of land holdings, which were selected by order of Russian Tsar Peter I.

The article focuses on the analysis of the character references presented by village councils and boards of collective farms in the Vinnytsia region for those people who were subject to exile to remote regions of the USSR in accordance with the Decree of the Presidium of the Supreme Soviet of the USSR “On the eviction of the individuals for evading agricultural work and leading an antisocial parasitic lifestyle from the territory of the Ukrainian SSR” of February 21, 1948. The research methodology is based on the combination of general scientific (abstraction, analysis and synthesis, generalization) and specific historical (historical and critical, historical and systemic, concrete and problematic, quantitative) methods with the principles of historicism, consistency and scientific nature. The paper’s scientific novelty lies in the analysis of the previously unexplored archival sources and documents which served as the basis for exiling the villagers to special settlements for 8 years. Conclusions. Materials of character references confirm the practice of permanent coercive methods of regimes in relation to the rural population that refused to work in collective farms primarily due to the lack of interest in the results of labor, minimal payment, or its complete absence.

The Role of Islamic Ideology in Iran-Pakistan Relations from 1947 to 1979
Authors: Qadir Abdul , Kasi Mirwais
Published: February 2022

Ideology is an important determinant in foreign policy.However, it has its implications. Pahlavi Shah's Westernization policies and their dissociation with Islamic ideology were the main features of their rule. The early leadership of Pakistan and Iran(Muhammad Reza Shah) were secular in outlook, paid little attention to ideology and had shared interests. While in Pakistan, the religious identity and its liberal national identity are still debated, and Pakistan has to reconcile between the two competing points of view. The Islamic revolution was unique in character as the earlier resolutions in the world were predominantly secular, while in Iran, it had religious trappings. The intellectuals in Iran like Jalal Al-Ahmed, Shariati, and all shades of parties played a significant role in inciting the people for the revolution. In South Asia, Allama Iqbal, Jamal ud-din Afghani, and Maulana Maududi influenced the people for Pan-Islamism and a utopian Islamic society. The after math of the Iranian revolution were grim, and people at the helm of affairs at the time of Shah were either executed or left the country for good. The relations between Zia ul-Haq and Khomeini, two proponents of Islamic ideology, were not good. Zia combined the elements of Islamism with pragmatism, while Khomeini was more radical and committed to its ideology.
