EFFECT OF Cu SUBSTITUTION ON THE STRUCTURE ELECTRICAL AND DIELECTRIC PROPERTIES OF   Co-Ni FERRITE MATERIALS
Creators: name: ADANE BOGALE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Synthesis and characterization of nanoparticles, which is less than 100 nm  ferrite materials
have gained much attention in recent years because of their unique properties and potential
for many applications such as magnetic storage systems, magnetic resonance imaging,
spintronics etc. Cu substitute Co0.7-xNi0.3CuxFe2O4  for x = 0.05 and 0.1  ferrite materials are
successfully synthesized by sol-gel method processing at pH  value  of 7. The synthesized
ferrites are annealed at  a temperature of  800 °C for 8 hrs. The  structure,  chemical
composition, electrical and dielectric properties of both ferrites are characterized by the x-ray
powder diffraction (XRD), energy dispersive X-ray spectroscopy  (EDX), Fourier transform
infrared (FT-IR) spectroscopy and complex impedance spectroscopy (CIS).
XRD analysis reveals that both ferrites show cubic spinel structure with space group Fd3m.
The lattice parameter decreases from 8.447Å to 8.441 Å with increasing Cu content from x =
0.05 to x = 0.1. The average crystallite sizes of the synthesized samples  are determined by
using the X-ray analysis broadening of the (311) diffraction peak by using Debye-Scherrer’s
formula and it is found in the values of 72 and 70.90 nm. The elemental analysis as obtained
from the EDX measurement  indicates the quantitative presence of Co, Ni, Cu, Fe and O in
the synthesized samples. It also confirms the absence of impurities in Co0.65Ni0.3Cu0.05Fe2O4
and Co0.6Ni0.3Cu0.1Fe2O4  ferrite samples. The FT-IR  spectra show  the tetrahedral stretching
vibration modes of Co0.65Ni0.3Cu0.05Fe2O4 and Co0.6Ni0.3Cu0.1Fe2O4  ferries.  The two strong
frequency bands  appeared at wavenumber 569.02 and 572.90 cm−1
  are responsible for the
formation of Co0.65Ni0.3Cu0.05Fe2O4 and Co0.6Ni0.3Cu0.1Fe2O4 ferrites, respectively.
From the electrical and dielectric properties studies, it is found that the value of the dielectric
constant
as well as the real impendence
 of both samples decreases exponentially with an
increasing frequency due to interfacial polarization. For the case of conductivity, the effect of
the variation of frequency on the electrical conductivity of both synthesized sample  are
identified. Their  conduction mechanism  is  explained on the basis of hopping of charge
carriers between Fe
2+
 - Fe
3+
 ions on octahedral sites.
title: Seeing Below The Surface Of Mars: Volatile sublimation in the martian regolith
Creators: name: Patel, Narissa
Publisher: name: The Open University
Year: 2022

description: The discovery of buried carbon dioxide (CO2) ice between water (H2O) ice layers within the martian south polar layered deposits has renewed interest in subsurface CO2 ice. In this thesis, subsurface CO2 ice stability is explored using a 1-D thermal and vapour diﬀusion numerical model that simulates three phases of H2O, two phases of CO2, and adsorption of both for the ﬁrst time.

 Numerical experiments were run to examine how these two ices inﬂuence one another, under a variety of ice-layer conﬁgurations that are expected to be valid for Mars. The results demonstrate that an overlying near-surface H2O ice-ﬁlled regolith layer increases subsurface CO2 ice stability by an order of magnitude. This stability increases further with the addition of an underlying H2O ice-ﬁlled regolith layer. The initial porosity and geological materials used to represent the subsurface also have a large inﬂuence on CO2 ice stability. The porosity limits the vapour diﬀusion rate, while the geological materials inﬂuence thermal conductivity and, therefore, subsurface temperatures.

 Simulations at diﬀerent orbital obliquities demonstrate that CO2 ice stability in the polar regions is greatest at low obliquities and smallest at high obliquities. The reverse is true for the equatorial regions. At higher obliquities (>45◦) and atmospheric pressures, the results suggest subsurface CO2 ice deposition could occur in the equatorial region.

 The model results suggest that a 0.7–27 km CO2 ice layer could sublimate away while 1 m of low-porosity H2O ice forms (in 14–550 kyr depending on method) in the south polar layered deposits. The results also suggest CO2 ice sublimation is dependent on obliquity: ∼0.15 km sublimates at low obliquity and ∼1.9 km sublimates at high obliquity over 100 kyr.

 The subsurface model is a useful tool for future investigations into the historical behaviour of ices on Mars, particularly during the Noachian period when the CO2 frost-point temperature was higher.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The main purpose of this study was to identify and characterize students‘ misconceptions
about basic electricity (simple electric circuit). The study was carried out in Heto
Secondary School in Hadya Zone with special reference to grade 10 students. Case study
was employed to address the problem. To conduct this study, 60 students were selected
through random sampling technique from total population of 360 students. In order to
achieve the objectives, the study employed conceptual understanding test and semi
structured interview about simple electric circuit. Each question in the conceptual
understanding test and interview was designed to probe students‘ knowledge and
understanding about electric circuit. All data collected using different tools were analyzed
quantitatively and qualitatively.
The study identified some students‘ misconceptions in electric circuit. These were: I)
some students believed that the total resistance of the circuit increased when two or more
resistors were connected in parallel, II) the power supply provided constant current
regardless of how the circuit is changed, III) only one wire connected to a battery was
needed for the circuit to work, IV) each device consumes some of current passing through
it and others. The study also described the causes for these misconceptions. These were
students‘ personal experience, inappropriate use of laboratory, and unevaluated text
books. Thus, to improve the situation, it is recommended that every educator should be
aware students back ground, their daily life experience, and their pre conceptions before
providing the lessons on electric circuit, teachers should also spent more time to produce
more conceptual talk about the topic to bring conceptual understanding, different
instructional methods should be applied to support conceptual understanding of students
about simple electric circuit. Replacing those misconceptions by scientifically accepted
conceptual views were necessary and efforts should be made to create awareness
continuously for students, teachers, school principals and educational experts. Conducting
trainings and different workshops with those concerned bodies was more advisable to
increase the understanding and to avoid misconceptions in basic electricity.

Республика Башкортостан

description: В статье отмечена необходимость исследования тенденций и величин изменения определенных агрометеорологических показателей на территории Республики Башкортостан. Указано, что в условиях изменяющегося климата важно выявить динамику температурного режима, влияющего на развитие сельскохозяйственных культур в период их вегетации. При этом достаточно информативным показателем является скорость нарастания положительных температур и интервал времени ее перехода через определенные пороговые значения, так как существует прямо пропорциональная связь скорости развития растений со скоростью нарастания температур. Впервые для изучаемой территории рассмотрена проблема изменения длительности времени перехода через пороговые температуры 0°, 5°, 10°, 15°С весной и осенью за период 1945–2018 гг. Установлено, что после года заметных климатических изменений в Республике Башкортостан самым стабильным и практически неизменным остался временной интервал перехода температур от 0° до 5°С весной и от 5° до 0°С осенью. Пространственные отличия в длине периода 5°–10°С по абсолютным значениям близки к этим показателям и также невелики. Однако на территории республики повсеместно существенно увеличена длительность весеннего периода нарастания температур 10°– 15°С. Особенно четко эта тенденция проявляется в пределах лесостепной и степной зон Русской равнины. Это приводит к заметному нарастанию продолжительности весеннего периода в пределах этих природных зон. Такая же тенденция наблюдается в данных природных зонах и в период начала осени, при переходе температур от 15° до 10°С. Проведенные исследования также фиксируют общее увеличение продолжительности осеннего периода на территории республики. При анализе географических закономерностей при изменении тенденций и продолжительности времени перехода между указанными пороговыми температурами ожидаемо проявляются различия, связанные с широтными изменениями температуры воздуха.

description: We report the discovery of two millisecond pulsars in a search for radio pulsations at the positions of \emph{Fermi Large Area Telescope} sources with no previously known counterparts, using the Nançay radio telescope. The two millisecond pulsars, PSRs J2017+0603 and J2302+4442, have rotational periods of 2.896 and 5.192 ms and are both in binary systems with low-eccentricity orbits and orbital periods of 2.2 and 125.9 days respectively, suggesting long recycling processes. Gamma-ray pulsations were subsequently detected for both objects, indicating that they power the associated \emph{Fermi} sources in which they were found. The gamma-ray light curves and spectral properties are similar to those of previously-detected gamma-ray millisecond pulsars. Detailed modeling of the observed radio and gamma-ray light curves shows that the gamma-ray emission seems to originate at high altitudes in their magnetospheres. Additionally, X-ray observations revealed the presence of an X-ray source at the position of PSR J2302+4442, consistent with thermal emission from a neutron star. These discoveries along with the numerous detections of radio-loud millisecond pulsars in gamma rays suggest that many \emph{Fermi} sources with no known counterpart could be unknown millisecond pulsars.

description: Every machine vibrates and emits noise. This is unused energy that, with an appropriate
mechanism, can be returned to the system. Utilizing an array of piezoelectric micro
electromechanical systems micro-electro mechanical system (MEMS) devices to harvest
this otherwise wasted energy; it is possible to improve the efficiency of any number of
mechanical devices. Piezoelectricity is the mechanism by which certain crystalline
structures generate electric potential when under strain, or, conversely, deform when
subjected to an electric potential. It is this first effect that is important to this application.
Though each micro-electro mechanical system (MEMS) device will generate a very small
amount of power, a 1 m
2
 area can contain an array of millions of these devices.
Energy harvesting, conservation, and efficiency are the universal application of these
devices makes them ideal for any expeditionary platform, such as ships, aircraft, and
automobiles. This project work designs and tests the first generations of acoustic and
vibrational piezoelectric micro-electro mechanical system (MEMS) devices; including
time-dependent finite element models, microfabrication processes, and the initial attempts
at characterization and optimization.

description: This paper studies the monotonicity of equilibrium costs and equilibrium loads in nonatomic congestion games, in response to variations of the demands. The main goal is to identify conditions under which a paradoxical non-monotone behavior can be excluded. In contrast to routing games with a single commodity, where the network topology is the sole determinant factor for monotonicity, for general congestion games with multiple commodities the structure of the strategy sets plays a crucial role.
 We frame our study in the general setting of congestion games, with a special focus on singleton congestion games, for which we establish the monotonicity of equilibrium loads with respect to every demand. We then provide conditions for comonotonicity of the equilibrium loads, i.e., we investigate when they jointly increase or decrease after variations of the demands. We finally extend our study from singleton congestion games to the larger class of constrained series-parallel congestion games, whose structure is reminiscent of the concept of a series-parallel network.

They are the general relativistic gravitoelectromagnetic (GEM) fields of the SBH, its quadrupole mass moment Q2, and a diffuse dark matter distribution around the SBH. All of them induce non-zero secular radial accelerations proportional to the eccentricity e of the orbit. By taking the S2 star, orbiting the SBH along a highly eccentric (e = 0.8831) ellipse with a period Pb = 15.9 yr, we numerically compute the magnitudes of its radial accelerations (Abridged).

description: В статье рассматриваются итоги работы офтальмологических отрядов, действовавших от имени Попечительства императрицы Марии Александровны о слепых в период 1893– 1917 гг. и охвативших практически всю Российскую империю. Из-за отсутствия специализированной офтальмологической помощи в большинстве населенных пунктов страны офтальмологические отряды, единственные в своем роде, возглавили продвижение доступной и бесплатной медицинской помощи населению. Авторы дают анализ работы офтальмологических отрядов на территории Уфимской губернии, выявивших большое количество нуждавшихся в лечебных мероприятиях в связи с болезнями глаз. Самым значимым результатом работы отрядов в Уфимской губернии стало формирование офтальмологической службы в регионе, начавшееся с развертывания первых двух глазных лечебниц. В статье использованы архивные документы из Российского государственного исторического архива и Национального архива Республики Башкортостан. Отчеты о выездах офтальмологических отрядов имели практическую значимость: они предоставляли статистические данные о распространенности глазных заболеваний у населения империи и тем самым помогали выстроить полноценную картину для дальнейшей тактики борьбы с ними. В этом направлении прекрасным дополнением стали работы профессоров С.С. Головина [1] и Л.Г. Беллярминова [7], дающие представление о ситуации в стране с распространением офтальмологических заболеваний и о роли отрядов в деле продвижения глазной помощи населению труднодоступных регионов. Труды профессора С.В. Лобанова [14] и врача М.М. Фиша [12] посвящены их работе в составе глазных отрядов на территории Уфимской губернии и состоянию офтальмологии в нашем регионе. Ценным литературным источником является работа В.В. Нероева с соавторами [5], где проводится параллель между прошлым и будущим оказания выездной помощи населению. Интересна работа А.А. Хитрова [8], характеризующая благотворительную направленность офтальмологической помощи, в частности, на выездах, и раскрывающая недостатки данной формы собственности. Статья раскрывает роль выездной офтальмологической помощи в зарождении и становлении офтальмологической службы в регионе. В работе, во-первых, показаны проблемы в деятельности офтальмологических отрядов, основу которых составили финансовый и кадровый дефицит, во-вторых, преемственность между частным благотворительным обществом и государственным учреждением здравоохранения на примере Уфимского отделения Попечительства императрицы Марии Александровны о слепых и Башкирским трахоматозным институтом Наркомздрава БАССР. Актуальность статьи обусловлена малоизученностью темы.
EXPLORING THE IMPACT OF CLASSROOM GROUP INTERACTION ON STUDENTS’ ACADEMIC ACHEIVEMENT IN PHYSICS: THE CASE OF BONOSHA SECONDARY AND PREPARATORY SCHOOL

description: The goal of this research was to explore the impact of classroom group interaction on
students’ academic achievement in physics. Both correlation and case study research designs
were used to answer the two  research questions. Is there significant relation  between
classroom group interaction and students academic achievement in physics? This research
question was answered by using Pearson correlation. How do classroom group interactions
affect students’ academic achievement? This  research question was answered by using case
study. Pearson Correlation was used to investigate the relationship between classroom group
interaction and students’ academic achievement in physics in Bonosha secondary and
preparatory school. Case study was used to examine how classroom group interactions affect
academic achievement. Pearson Correlation analyse showed that there is positive correlation
between classroom group interaction and students’ academic achievement. The results of this
study showed that classroom group interactions affect students’ academic achievement while
student-  student interaction is disrespectful. Descriptive case study analyses indicated that
teacher’s lack of supportive relationship/interaction, reluctance to work in groups, absence of
group leader, teacher’s lack of supportive relationship/interaction, teacher’s failure to give
clear explanation for the given tasks, and absence of face to face interaction were  the major
factors that have been affecting the implementation of classroom group interaction which in
turn affect students’ academic achievement. The results suggest the need for teachers to be
provided with appropriate resources and assistance to meet the needs of their students beyond
academic instruction. More over it was suggested that an attempt must be made to use group
work activities regularly and students should be made to take part in meaningful classroom
group interaction.

description: We study the evaporation of planets orbiting close to hot (extreme) horizontal branch (EHB) stars. These planets survived the common envelope phase inside the envelope of the reg giant star progenitor. We find that Jupiter-like planets orbiting within 10Ro from an EHB star suffers a non-negligible mass-loss during their 10^8 yr evolution on the horizontal branch. The evaporated gas is ionized and becomes a source of Balmer lines. Such planets might be detected by the periodic variation of the Doppler shift of the Balmer lines.

description: A measurement of the Higgs boson (H) production via vector boson fusion (VBF) and its decay into a bottom quark-antiquark pair ($\mathrm{b\bar{b}}$) is presented using proton-proton collision data recorded by the CMS experiment at $\sqrt{s}$ = 13 TeV and corresponding to an integrated luminosity of 90.8 fb$^{-1}$. Treating the gluon-gluon fusion process as a background and constraining its rate to the value expected in the standard model (SM) within uncertainties, the signal strength of the VBF process, defined as the ratio of the observed signal rate to that predicted by the SM, is measured to be $μ^\text{qqH}_\mathrm{Hb\bar{b}}$ = 1.01 $^{+0.55}_{-0.46}$. The VBF signal is observed with a significance of 2.4 standard deviations relative to the background prediction, while the expected significance is 2.7 standard deviations. Considering inclusive Higgs boson production and decay into bottom quarks, the signal strength is measured to be $μ^\text{incl.}_\mathrm{Hb\bar{b}}$ = 0.99 $^{+0.48}_{-0.41}$, corresponding to an observed (expected) significance of 2.6 (2.9) standard deviations.

Channel stability in alluvial gravel-bed streams
Creators: name: MacKenzie, Lucy
Publisher: name: University of British Columbia
Year: 2019

description: Alluvial fans, conic depositional landforms that develop where headwater streams outlet into a main valley, are desirable locations for development in mountainous regions worldwide. Alluvial fans may become hazardous during high flow events; the relatively high gradient and the abundance of loosely packed sediment allows alluvial fan channels to undergo rapid morphodynamic change, putting bordering infrastructure at great risk. Despite these hazards, our understanding of channel dynamics on alluvial fans remains limited. Through physical modelling, this thesis investigates the processes contributing to channel stability in such environments. Using three sets of paired experiments, I show that channel stability is mediated by the mobility of the largest grains in the channel. Pairs of experiments were identical in all regards (i.e. discharge, sediment supply, gradient, median grain size), the only difference was a slight increase in the proportion of large grains found in the bed material, while the median sediment size for the experimental pairs remained essentially the same. Overall, I found that channels with bed material containing fewer large grains experienced two to four times as much erosion and deposition across a range of discharges and rates of sediment supply. These findings contradict the conventional models of channel stability, that use the median grain size to represent the bed surface; these models commonly assume that streams undergo morphodynamic change once that grain size is mobile. My experiments demonstrate that channel stability is linked to the mobility of the largest grains, not the median size. Using high resolution models of the bed surface, I show that the channels containing the greater proportion of large grains tend to be more stable due to their increased frequency at the bed surface. Based on these results, I propose a three phase model of channel stability wherein the thresholds between stable/dynamically stable and dynamically stable/unstable are governed by the thresholds of entrainment and full mobility of the largest grains, respectively. This new model of channel stability could improve our capacity to predict when catastrophic events may occur in steep, alluvial channels.

description: The mass assembly of galaxies leaves imprints in their outskirts, such as shells and tidal tails. The frequency and properties of such fine structures depend on the main acting mechanisms - secular evolution, minor or major mergers - and on the age of the last substantial accretion event. We use this to constrain the mass assembly history of two apparently relaxed nearby Early-Type Galaxies (ETGs) selected from the Atlas-3D sample, NGC 680 and NGC 5557. Our ultra deep optical images obtained with MegaCam on the Canada-France-Hawaii Telescope reach 29 mag/arcsec^2 in the g-band. They reveal very low-surface brightness (LSB) filamentary structures around these ellipticals. Among them, a gigantic 160 kpc long tail East of NGC 5557 hosts gas-rich star-forming objects. NGC 680 exhibits two major diffuse plumes apparently connected to extended HI tails, as well as a series of arcs and shells. Comparing the outer stellar and gaseous morphology of the two ellipticals with that predicted from models of colliding galaxies, we argue that the LSB features are tidal debris, the star-forming objects near NGC 5557, long lived Tidal Dwarf Galaxies and that each of the two ETGs was assembled during a relatively recent, major wet merger, which likely occurred at a redshift below z = 0.5. The inner kinematics of NGC 680 is typical for fast rotators which make the bulk of nearby ETGs in the Atlas-3D sample. NGC 5557 belongs to the poorly populated class of massive, round, slow rotators that are predicted by semi-analytic models and cosmological simulations to be the end-product of a complex mass accretion history, involving ancient major mergers and more recent minor mergers. Our observations suggest that under specific circumstances a single binary merger may dominate the formation history of such objects and thus that at least some massive ETGs may form at relatively low redshift (abridged).

description: Статья посвящается проблемам классификации мифологизированных персонажей башкирской мифологии группы «невольные носители зла и добра». Данную группу персонажей условно можно разделить на две подгруппы. Первую подгруппу составляют персонажи, называемые «люди с удачливой рукой (ногой)», «люди с удачливой дорогой» и др. Ко второй подгруппе относятся персонажи, которых в этнографии называют «люди с дурным глазом, или глазливые», «люди с невезучей дорогой, или бездорожные», «люди с тяжелой невезучей рукой (ногой)». В статье раскрывается этиология каждой подгруппы персонажей. В частности, судя по материалу, появление удачливых людей связано с получением отдельными людьми ҡот ‘жизненной силы’ и өлөш ‘особой доли’ от высших сил. По представлениям башкир, носители добра являются любимцами Аллаха / Худая. Полученным даром они щедро делятся с другими, одаривая всех окружающих ҡот и өлөш. В статье приводятся общие и локальные названия персонажей данной группы, выделяются наиболее распространенные термины, относящиеся к каждой подгруппе. В работе более широко освещается этиология группы персонажей, которых в этнографии называют «невольными носителями зла». По представлениям башкир, у данной группы персонажей вредоносные свойства бывают как врожденными, так и приобретенными в результате нарушения каких-либо табу или других предписаний. В частности, новорожденный, оставленный один до 40 дней, может стать носителем вредоносных свойств. В этнографии многих народов, в том числе и башкир, вредоносным мог быть человек, рожденный вне брака, люди, имеющие какие-либо изъяны, сироты и другие обездоленные, ущербные люди. По представлениям башкир, ущербные, завистливые люди способны нанести вред человеку с помощью тяжелого взгляда, дурных помыслов, различных манипуляций и др. Что же касается врожденной вредоносности, характерной для отдельных персонажей башкирской мифологии, то их появление в том или ином человеке связано с грехами, получением проклятий, нарушением табу его родителями или другими предками. В статье отмечается, что как первая, так и вторая подгруппа персонажей наделена некими ирреальными свойствами, о присутствии которых эти персонажи не знают, но тем не менее они могут нанести вред или, наоборот, наделить окружающих добром, благостью, везучестью. В статье, опираясь на этнографические, фольклорные и лингвистические материалы, описываются основные представители каждой подгруппы, приводятся параллели из других тюркских традиций, объясняется происхождение мифологических представлений, связанных с «невольными носителями добра и зла» у башкир.
Secondary star formation within massive star clusters: Origin of multiple stellar populations in globular clusters

description: We numerically investigate whether and how gaseous ejecta from AGB stars can be converted into new stars within originally massive star clusters (MSCs) in order to understand the origin of multiple stellar populations in globular clusters (GCs). We adopt a scenario in which (i) MSCs with masses of M_s can be formed from high-mass, high-density giant molecular clouds (GMCs) in their host galactic building blocks embedded in dark matter halos at high redshifts and (ii) their evolution therefore can be significantly influenced by M_s, their initial locations, and physical properties of their hosts. Our 3D hydrodynamical simulations show that gaseous ejecta from AGB stars can be retained within MSCs and consequently converted into new stars very efficiently in the central regions of MSCs, only if M_s exceed a threshold mass (M_th) of ~10^6 M_sun. The new stars can correspond to the ``second generation (SG)'' of stars with higher Na and lower O abundances observed in GCs. Star formation efficiencies during the formation of SG stars within MSCs with M_s > M_th can be rather high (0.3-0.9) so that very compact new clusters within original MSCs can be formed. M_s should be as large as 10^6-10^7 M_sun to explain the observed large fraction of SG stars in the present ordinary Galactic GCs, because new stars can consist of only 1-4% among all stars for the standard IMF. Nuclear MSCs are found to retain much more effectively the AGB ejecta and convert more efficiently the gas into new stars owing to much deeper gravitational potential of their hosts. We suggest that both M_s and their locations within their hosts can determine whether abundance spread can be seen only in light elements or even in heavy ones.

Subjects: : Loneliness, disability, social well-being

description: Loneliness is an emotional state characterized by feelings of isolation and disconnection from others which is perceived to be influenced by many factors. This study employs a comprehensive review methodology utilizing the Prismal Model, ensuring a systematic approach to inclusion and exclusion criteria. By meticulously analyzing relevant literature, this study aims to provide a holistic understanding of the effect of loneliness on social well-being of individual with disability yielding valuable insights for future research and practical applications. This study find a significant effect of loneliness on the social well-being of people with disability in Nigeria. Nigeria been a developing country, little things were done in favor of disable people to make life easy for them and enhance their optimal participation in the society. This study find no statistical significant difference in the experience of loneliness among individuals based on the type of disability they possess. It’s important that more attention should be given to the social well-being of people with any form of disability. Structures that help their maximal participation in the society such as improving accessibility in infrastructure and transportation, along with providing assistive technologies, is essential. Expanding economic opportunities through inclusive employment policies, vocational training, and entrepreneurship support is crucial. Strengthening institutional support by enforcing disability rights laws, promoting inclusive education, and improving healthcare services is necessary. Advocacy organizations and representation in policymaking ensure their voices are heard. Enhancing social support systems, including caregiver support and mental health services, further reduces loneliness and improves quality of life

description: В статье рассматривается распространенность разводов у мусульманского населения Уфимской губернии (башкир, татар, мещеряков и тептярей) во второй половине ХIХ в. в пореформенный период. Краткий анализ научной литературы показывает, что проблема разводов изучалась лишь у башкир, у других же народов края – нет. Исследователи считали, что разводы у башкир были нередким явлением. Источниками для данной работы послужили опубликованные и неопубликованные статистические материалы, которые были составлены в 1860–1880-е гг. по вероисповеданиям. Статистика разводов после 1890 г. не обнаружена. Автор впервые вводит в научный оборот статистические материалы по разводам за некоторые годы. В статье сопоставляется коэффициент разводимости по губернии за указанный период с аналогичными сведениями за 1930–60-е гг. по Башкирской АССР, а также за 1880-е гг. у народов Средней Азии. В то же время введение в научный оборот сохранившихся поуездных статистических материалов по разводам в 1870-е гг. позволяет выявить особенности распространения разводов по конкретным уездам и народам края. Так, в тех уездах, где башкиры составляли большинство мусульманского населения, коэффициент разводимости был существенно ниже, чем в западных уездах, в которых доминировали тептяри, мещеряки и татары. Все это позволяет сделать вывод, что у башкир разводы практиковались все же меньше, чем у других мусульманских народов края. Несмотря на широкую распространенность, разводы в тот период практически не влияли на уровень рождаемости, который оставался очень высоким.
