Authors: Sutherland Oliver , Kafwimbi Stefan , Chinyama Jonathan , Sichone James , Bwanga Osward
Published: December 2022

Background: Globally, breast cancer among females is the number one cause of morbidity at 11.6% and is the leading cause of mortality at 6.6%. In Zambia, it is the most common malignancy among women. However, the demographic characteristics of suspected breast cancer female patients accessing ultrasound breast cancer services in Zambia are still unclear. Objective: This study aimed to determine the demographic characteristics of suspected female breast cancer patients. The demographic characteristics may then be used by responsible authorities such as the Ministry of Health (MoH) in Zambia and aligned Non-governmental organisations (NGOs) such as the Zambia cancer association in concentrating their efforts to curtail the scourge. Methods: Systematic random sampling was used for the selection of participants in this study. The selected participant’s demographic information was obtained from their medical records such as the medical files, Cancer Diseases Hospital (CDH) ultrasound register and University Teaching Hospital (UTH) histology registers. Further, the researcher personally interviewed the selected participants to obtain the demographic information required for the study. Results: The median age for the study participants was 43, with the interquartile range (IQR)=36-50. The median parity status was 3, with IQR=1-5. The majority of breast cancer patients were married (57) (55.9%) and employed (80) (78.4%). There was no significant difference in education level and classification of residence for study participants between participants with a histology-positive and histology-negative result, P greater than 0.05. Conclusion: This study has found evidence that the reproductive age group, low to no parity status, married marital status and employed employment status are associated with breast cancer. Education level and classification of residence did not show any association with breast cancer in this study.

Authors: - Peter Obeng , - John Kofi Brewu , - Edward Opoku
Published: December 2022

The purpose of the study was to collect some indigenous and folk-game songs that are developmentally appropriate for teaching and learning in early childhood education setting. The research identified some of the repertoire pre-school children use during musical activities and collected some indigenous songs and folk game songs for teaching and learning in early childhood settings. The researchers Adopted qualitative research approach supported by interpretivists’ paradigm and implemented the case study strategy. Purposive sampling technique was used to select twenty five participants (twenty pupils, four teachers, and one early childhood coordinator).The schools were conveniently selected. The instruments used were interview, observation and Ghanaian pre-school Creative Arts Curriculum. Findings revealed that indigenous and folk games songs in teaching would bring pre-school children to interact with environment since teachers will be compared to prepare teaching and learning aids using local materials of which pupils may be conversant with and this will make concept learning easier. The implication is that the use of Indigenous materials for teaching music are in line with the multiple intelligences by Gardner as it echoes cultural education and total development of the child. Teachers should not exhaust the early childhood music curriculum with Western and contemporary music, and leave no room for Ghanaian children’s indigenous and folk songs. Teachers should also apply diverse pedagogical strategy to unearth children’s musical intelligences through the use of indigenous and folk game songs.

An Analysis of Occupational Stress among College and School Teachers During COVID-19 Pandemic with Special Reference to Pavaratty Region
Authors: - Swaliha Mariyam K.N.
Published: December 2022

The COVID-19 pandemic has brought enormous changes in the working pattern of teachers. The noteworthy changes are work from home and usage of electronic gadgets for official work. The methodology of teaching too changed from physical classrooms to online modes. This compulsion to change the working pattern brought high challenge to the teachers which lead to occupational stress in them. In this paper, the attempts have been made to study the level of occupational stress, factors related to it and to identify the barriers that school and college teachers experienced while working during the pandemic. For this purpose analytical research design was adopted and convenience sampling with self administered questionnaire was used for data collection. IBM SPSS and Microsoft Excel is used for the data analysis and then the inferences were drawn. The study reveals that, there is a high level of prevalence of occupational stress among the school and college teachers during online teaching. The reduction of occupational stress will induce the teachers to provide efficient and effective service to the society. So, this study calls for appropriate interventions taken by the authorities to reduce stress among school and college teachers and to resolve causes of occupational stress among them.
Transcriptomic Analysis of Aromatic Amino Acid Biosynthesis Under Nitrogen Starvation in Saccharomyces Cerevisiae
Authors: - Mehmet Şerafeddin Solak , - Tülay TURGUT GENÇ
Published: December 2022

Yeast Saccharomyces cerevisiae has been a preferred organism for scientific research on many sensing and signaling processes. Its ability to adapt to changes in reproductive conditions, especially its fermentative properties have made this yeast species an industrially important species. Because of that S. cerevisiae has been genetically modified to create many kinds of beneficial chemicals from biomass. S. cerevisiae cells have the ability to detect the quality of nitrogen sources in their environment. And It has many regulatory mechanisms to utilize alternative nitrogen sources after the favored sources have been depleted. And proline is the least desired nitrogen source for many laboratory yeast strains. Usage of proline results in the slowest growth rates. The yeast S. cerevisiae can only get cellular nitrogen from tryptophan, tyrosine, or phenylalanine. The major products of this catabolism are tryptophol, phenylethanol, and tyrosol, which are elements of the mixture of alcohols known as fusel oil and this makes yeast S. cerevisiae important also in the production of seconder metabolites. Next Generation Sequencing allows deep analysis of gene expression. The effect of growth in media containing poor nitrogen source, proline, on the aromatic amino acid biosynthetic pathway was observed using NGS technologies in this work. According to the transcriptomic analysis results, we found that 14 genes are responsible for aromatic amino acid biosynthesis and 12 genes (ARO1, ARO2, ARO4, ARO7, ARO8, ARO9, PHA2, TRP1, TRP2, TRP3, TRP4, and TYR1) were down-regulated, while 2 genes (ARO3 and TRP1) were up-regulated. In addition, ARO1, ARO2, ARO4, ARO7, ARO9, PHA2, TRP1, TRP2, TRP3, TRP4, and TYR1 genes have showed 1.5-fold or more expression.
A Critical Study on Why Did People, ‘Accustomed to Nakedness’, Begin to Cover or Decorate Their Bodies?

Published: December 2022

Evidence of the very first clothing is mostly indirect. Almost all of what we know about early clothes is based on conjecture and assumption. It is impossible to say when humans first started wearing garments. Based on the cave drawings, carved figures and other such evidences including remnants and traces of very early cloths, the archeologists suggested that humans may have begun wearing clothing between 100,000 to 500,000 years ago. Neanderthal man, who lived between 200,000 B.C.E. to 30,000 B.C.E., learnt to use the hides of the animals they hunted to keep themselves warm and dry, referred as the first known person to fabricate clothing. It's also possible that clothes were designed for other functions at first, such as adornment, worship, or prestige, and were later discovered to be useful as well. This paper includes the investigation about need and psychology behind the origin of clothing through some fundamental theories of clothing and their applications to perform very specific functions. This research aims to reveal fashion concepts, as well as the path from prehistoric man's clothing demands to present fashion trends. Furthermore, it lays the foundation for those who are keen to learn fashion by starting a discussion on why people wear clothes so that the readers/ fashion graduates and professionals can recognize the motivations behind the desires of individuals in order to design and construct clothes in creative ways to maximize wearer’s satisfaction level.

Фрагмент лексической системы казымского диалекта хантыйского языка: глаголы pitti ‘упасть, попасть’ и χɔjti ‘задеть, попасть’ и их аргументная структура
Authors:   HSE University (Moscow), Ryzhova Daria
Published: December 2022

The study describes the semantics of the Kazym Khanty verbs pitti ‘to fall; to get into somewhere’ and χɔjti ‘to touch; to hit the target’ as analyzed from the perspective of the frame-based approach to lexical typology. According to this approach, semantic fields consist of certain situation types, or frames, which are denoted by the lexemes belonging to the field. The situation types correspond to distributional patterns and serve as a basis for cross-linguistic comparison of word meanings. The paper identifies and illustrates the sets of physical meanings of the verbs in question, with a special focus on the domain of variation between pitti and χɔjti. It is shown that these verbs concur in contexts involving the semantics of either getting (occasionally) into somewhere (cf. A fly got into my soup) or hitting the target (cf. The arrow hit him in the arm). Evidence from Kazym Khanty, as well as from available cross-linguistic data, suggests that these meanings are adjacent to each other, while the meaning ‘to get into somewhere’ is closer to the domain of falling, and the meaning ‘to hit the target’ is closer to the domain of physical contact. Thus, the meanings ‘to fall’, ‘to get into somewhere’, ‘to hit the target’, and ‘to touch’ form a semantic continuum with no clear-cut boundaries between the semantic fields. This hypothesis is further supported by morphosyntactic variation in encoding of the patientive argument of the verb χɔjti, which seems to be influenced by the morphological pattern inherent to the verb pitti.
Отражение особенностей говоров жителей Семиреченской области в «Сказке о Кара-Мергене»

Published: December 2022

The article describes vowel and consonant features of “The Tale of Kara-Mergen” (Kazan, 1901) from N. N. Pantusov’s collection which was recorded in Semirechye. The author considers in detail the monument`s writing system and analyzes the phonological and morphological features of the text’s language in comparison with the data of previously studied Cyrillic books in the Kazakh language [Wisdom of Jesus the Son of Sirach 1891; Primer for Kyrgyz people 1892; School of Piety 1892; The Baptism of Russia 1892], which were published within the framework of the Kyrgyz mission at the end of 19th and the beginning of the 20th century. The analysis showed that the vocalism presented in “Kara-Mergen” does not differ significantly from the vocalism of the compared first Cyrillic books in Kazakh. A review of examples illustrating the tendencies of labial vowel harmony showed that the labialization of narrow vowels of the second, third and fourth syllables is fixed in writing in all cases. As a result of the study, it was concluded that the system of vowel harmony in “Kara-Mergen” differs from the literary Kazakh language and from the first books studied earlier. This confirms the fact that scientists have not previously studied the first books in the Semirechensk dialect. An analysis of the accusative affix, the archaic version of which (-ny) sporadically preserved in “Kara-Mergen” and in Western [Wisdom 1891] and Northern [Primer 1892] dialect books, shows that its change, apparently, was not yet completed at the end of the 19th century.
Макроструктурный анализ повествовательных текстов тюркоязычных школьников-билингвов

Published: December 2022

The present study is devoted to the analysis of the macrostructure of oral narrative texts of Turkic-speaking bilingual schoolchildren. The research material was obtained using a MAIN — Multilingual Assessment Instrument for Narratives — a tool for assessing the narrative abilities of bilinguals. Subjects for the analysis represent the most common language groups among children in Kazakhstan. The results of the study differ significantly from previous findings regarding the ratio of qualitative and quantitative indicators of the macrostructural complexity of bilingual stories in two languages, as well as in the comparative description of the features of closely related languages, their connections, similarities and differences in the conditions of bilingualism and multilingualism. Observations show that narrative competence develops depending on the subject’s age and propensity for storytelling and becomes fully structured only in the adulthood. Children begin to create narratives at about two years old, and from that moment their narrative competence develops intensively, although at different rates speed. A closer look at the various macrostructural components showed that the production was strikingly similar in the three language groups, both for frequently used and rarely encountered components of the macrostructure. The complexity of the plot was also considered from the other side — by estimating the number of episodes in which participants implemented complete GАО sequences. In all three language groups, on both L1 and L2, most speakers used at least one complete sequence. Nevertheless, it becomes clear that when conducting scientific research on bilingualism in the republic, it is necessary to take into account the regional socio-economic, demographic and ethno-linguistic conditions that have historically developed on the vast territory of the country.
The Origin of High-energy Emission in the Young Radio Source PKS 1718–649

Published: December 2022

We present a model for the broadband radio-to-γ-ray spectral energy distribution of the compact radio source PKS 1718–649. Because of its young age (≃100 yr) and proximity (z = 0.014), PKS 1718–649 offers a unique opportunity to study the nuclear conditions and the jet/host galaxy feedback process at the time of the initial radio jet expansion. PKS 1718–649 is one of a handful of young radio jets with γ-ray emission that has been confirmed by the Fermi/LAT detector. We show that in PKS1718−649 this γ-ray emission can be successfully explained by Inverse Compton scattering of the UV photons, presumably from an accretion flow, off nonthermal electrons in the expanding radio lobes. The origin of the X-ray emission in PKS 1718–649 is more elusive. While Inverse Compton scattering of the IR photons emitted by a cold gas in the vicinity of the expanding radio lobes contributes significantly to the X-ray luminosity, the data require an additional source of X-rays, e.g., a weak X-ray corona or a radiatively inefficient accretion flow, as expected from a LINER-type nucleus, such as that of PKS 1718–649. We find that the jet in PKS 1718–649 has low power, L

The inferred mass accretion rate and gas mass reservoir within 50–100 pc of the galactic center are consistent with estimates from the literature obtained by tracing molecular gas in the innermost region of the host galaxy with SINFONI and the Atacama Large Millimeter/submillimeter Array.

Our Milky Way should host an ancient, metal-poor, and centrally concentrated stellar population, which reflects the star formation and enrichment in the few most massive progenitors that coalesced at high redshift to form the proto-Galaxy. While metal-poor stars are known to reside in the inner few kiloparsecs of our Galaxy, current data do not yet provide a comprehensive picture of such a metal-poor “heart” of the Milky Way. We use information from Gaia Data Release 3, especially the XP spectra, to construct a sample of 2 million bright (G
BP < 15.5 mag) giant stars within 30° of the Galactic center (GC) with robust [M/H] estimates, δ[M/H] ≲ 0.1. For ∼1.25 million stars we calculate orbits from Gaia Radial Velocity Spectrometer velocities and astrometry. This sample reveals an extensive, ancient, and metal-poor population that includes ∼18,000 stars with −2.7 < [M/H] < −1.5, representing a stellar mass of ≳5 × 107

around the GC, with most orbits confined to the inner Galaxy. At high orbital eccentricities, there is clear evidence for accreted halo stars in their pericentral orbit phase. Most stars show [α/Fe] enhancement and [Al/Fe]–[Mn/Fe] abundances expected for an origin in the more massive portions of the proto-Galaxy. Stars with [M/H] < −2 show no net rotation, whereas those with [M/H] ∼ −1 are rotation dominated. These central, metal-poor stars most likely predate the oldest disk population (τ
age ≈ 12.5 Gyr), which implies that they formed at z ≳ 5, forging the proto-Milky Way.

Generating large-volume hydrodynamical simulations for cosmological observables is a computationally demanding task necessary for next-generation observations. In this work, we construct a novel fully convolutional variational autoencoder (VAE) to synthesize hydrodynamic fields conditioned on dark matter fields from N-body simulations. After training the model on a single hydrodynamical simulation, we are able to probabilistically map new dark-matter-only simulations to corresponding full hydrodynamical outputs. By sampling over the latent space of our VAE, we can generate posterior samples and study the variance of the mapping. We find that our reconstructed field provides an accurate representation of the target hydrodynamical fields as well as reasonable variance estimates. This approach has promise for the rapid generation of mocks as well as for implementation in a full inverse model of observed data.
Proton and Helium Heating by Cascading Turbulence in a Low-beta Plasma

How ions are energized and heated is a fundamental problem in the study of energy dissipation in magnetized plasmas. In particular, the heating of heavy ions (including 4He2+, 3He2+, and others) has been a constant concern for understanding the microphysics of impulsive solar flares. In this article, via two-dimensional hybrid-kinetic particle-in-cell simulations, we study the heating of helium ions (4He2+) by turbulence driven by cascading waves launched at large scales from the left-handed polarized helium ion cyclotron wave branch of a multi-ion plasma composed of electrons, protons, and helium ions. We find significant parallel (to the background magnetic field) heating for both helium ions and protons due to the formation of beams and plateaus in their velocity distribution functions along the background magnetic field. The heating of helium ions in the direction perpendicular to the magnetic field starts with a lower rate than that in the parallel direction, but overtakes the parallel heating after a few hundreds of the proton gyro-periods due to cyclotron resonances with mainly obliquely propagating waves induced by the cascade of injected helium ion cyclotron waves at large scales. There is, however, little evidence for proton heating in the perpendicular direction due to the absence of left-handed polarized cyclotron waves near the proton cyclotron frequency. Our results are useful for understanding the preferential heating of 3He and other heavy ions in the 3He-rich solar energetic particle events, in which helium ions play a crucial role as a species of background ions regulating the kinetic plasma behavior.
The Variation of the Solar Wind Correlation Scale and Taylor Scale Upstream of Mars Observed by MAVEN
Authors: Cheng Long , Wang Yuming
Published: December 2022

The correlation scale and Taylor scale, which characterize the turbulence and dissipation levels, of the solar wind upstream of Mars are determined using the Mars atmosphere and volatile evolution magnetic field data from 2015 to 2020, which covers half of a solar cycle from the solar maximum to the solar minimum. Our analysis suggests that the correlation scale varies between 10 and 20 hr and the Taylor scale between 0.3 and 1 s. Applying the frozen-in flow approximation, we convert the two temporal scales to the two spatial scales, which are about (1.5–3.0) × 107 km and 150–500 km, respectively. We further compare the correlation scale and Taylor scale to the sunspot number (SSN) to study the impacts of solar activity. The highest correlation coefficient between the correlation scale and the SSN is 0.78, where the two data sets are shifted by 16 months with the correlation scale behind the SSN. For the Taylor scale, the highest correlation coefficient is 0.52 with the time lag of 17 months. We also analyze the effective magnetic Reynolds number that is the square of the ratio of the two scales. It is more than 3 × 109, suggesting the good assumption of the frozen-in flow. However, its correlation with the SSN is weak.

In this work, we calculate the merger rate of primordial black hole–neutron star (PBH–NS) binaries within the framework of ellipsoidal-collapse dark matter models and compare it with that obtained from spherical-collapse dark matter halo models. Our results exhibit that ellipsoidal-collapse dark matter halo models can potentially amplify the merger rate of PBH–NS binaries in such a way that it is very close to the range estimated by the LIGO–Virgo observations. In contrast, spherical-collapse dark matter halo models cannot justify PBH–NS merger events as consistent results with the latest gravitational wave data reported by the LIGO–Virgo collaborations. In addition, we calculate the merger rate of PBH–NS binaries as a function of PBH mass and fraction within the context of ellipsoidal-collapse dark matter halo models. The results indicate that PBH–NS merger events with masses of M

Published: December 2022

BACKGROUND: Physical activity, healthy diet and avoiding risk factors are essential for a healthy lifestyle of older adults and for their life satisfaction.

AIM: The aim of the research was to determine the connection between lifestyle and life satisfaction of older adults in relation to the living environment (home environment, institutional environment).

METHODS: The research was based on a non-experimental quantitative research approach. We used the Oldwellactive standardised questionnaire to obtain lifestyle data and the SWLS scale to determine life satisfaction. The study included 656 older adults with an average age of 78.2 years who lived in a domestic (n = 380) and institutional environment (276).

RESULTS: Older adults living in the home environment rate their lifestyle higher (AV = 2.38, SD = 0.77) than those in the institutional environment (AV = 2.31, SD = 0.88), the difference is not statistically significant p = 0.304). Eating habits with regard to the location of residence showed statistically significant differences in the consumption of meat, fish and fish products and milk and dairy products (p <0.001). In the institutional environment, older adults are more likely to perform balance-enhancing exercises, while they consume more alcohol in the home environment. By assessing conditional associations, we establish a positive association between life satisfaction and lifestyle (estimated value = 21,600, p = 0,000). Older adults living in the institutional environment are more satisfied with life (v= 23,097) than those living in the home environment (N= 21.774).

CONCLUSION: The satisfaction of older adults with their life increases if an individual’s lifestyle improves. Older adults living in the institutional environment are more satisfied with life than those living in the home environment. In the future, it will be necessary to pay more attention to the study of living in a home environment, in accordance with the strategy of long-term care for the older adults.

BACKGROUND: COVID-19 is a condition that is characterized by an abnormal coagulation state, which is a reason for severe thrombotic problems.
AIM: We aim to determine the correlation of coagulation parameters levels with clinical outcomes of critically ill patients with COVID-19 admitted to intensive care at a national referral hospital in Indonesia.
METHODS: This retrospective cohort study analyzed 227 patients with a primary diagnosis of COVID-19 on mechanical ventilation who were admitted to the COVID-19 intensive care unit, Dr. M. Djamil from 2020 to 2021 taken in the medical record. Numerical data were analyzed using an independent t-test, while the categorical data were analyzed using the Chi-square test.
RESULTS: One hundred and one patients were >65 years old. The mean ± SD of INR levels, D-dimer levels, and platelet count on the first and the 5th days were 1.22 ± 0.77 and 1.36 ± 1.16; 4.624 ± 3.533 μg/L and 4.334 ± 3.365 μg/L; and 160.162 ± 117.203/μl and 234.070 ± 126.816/μl. There was a significant correlation between age (p = 0.002), INR levels on the 5th day (p = 0.041), platelet count on the 5th day (0.012) with clinical outcomes of patients.
CONCLUSION: There is a significant increase in the average platelets and INR levels on day 5. There is a significant correlation between INR levels and platelet count on 5th days with clinical outcomes of patients.
