Published: October 2023

In the current study, the PS/SiC/Sb2O3 nanocomposites have been prepared by using solution casting method with different concentrations of SiC/Sb2O3 nanoparticles (0,2,4,6,8) % wt. The structural and dielectric properties of (PS/SiC/Sb2O3) nanocomposites have been investigated. Full emission scanning electron microscope (FE-SEM) used to study the surface of nanocomposite. FE-SEM confirmed that good distribution of SiC and Sb2O3 NPs into the polymer matrix. Optical microscope (OM) was tested the morphological of nanocomposite  that proven that the  polystyrene is exceptionally miscible, as seen by its finer form and smooth, homogeneous surface, while the additive concentration SiC and Sb2O3 NPs  are well distributed on the surface of the polymer nanocomposite films. Fourier transformation spectroscopy (FTIR) was examine the structural of nanocomposite and give the information of the vibration of molecules. From FTIR, the  additive  SiC and Sb2O3 NPs caused interaction with polymer matrix. FTIR proven that there is physical interactions between polystyrene and SiC and Sb2O3 NPs. According to AC electrical properties, dielectric constant and dielectric loss of the NCs reduce with increasing the frequency of the applied electric field and increased with increasing concentration of SiC/Sb2O3 nanoparticles, while AC electrical conductivity increased with increasing frequency and concentration of SiC/Sb2O3 NPs. The results of structural and electrical characteristics show that the PS/SiC/Sb2O3 nanocomposites may be used for various electronics devices.
The Role of Surface in Hydride Formation Processes

Published: October 2023

Several LaNi5-based hydrogen storage alloys were studied using secondary ion mass spectrometry (SIMS) technique. Ar+ ions with the energy of 10 - 18 keV were used as primary ions. The study of the initial stages of the processes of LaNi5-based alloys interaction with hydrogen under the experimental conditions showed that on the areas of clean surface, hydrogen formed chemical compounds with the both of the main components of the alloy: nickel and lanthanum. As hydrogen accumulates on the surface and in the near-surface region, a hydrogen-containing structure is formed, which is characterized by a certain stoichiometric ratio of components. Nickel in this structure has strong chemical bonds with two hydrogen atoms, and lanthanum – with two or more hydrogen atoms. Along with such compounds, some structures with lower hydrogen content are also formed. The formed hydrogen-containing structure includes both main alloy components, La and Ni for all the studied samples, even though only lanthanum is generally accepted to be the hydride-forming element in such alloys. The SIMS studies of the chemical composition of the surface monolayers of the intermetallic alloy LaNi5, in the process of its interaction with oxygen, showed the following. As a result of the oxygen interaction with the alloy, a complex chemical structure including oxygen, lanthanum and nickel is formed on the surface and in the near-surface region of LaNi5. Oxygen in such a structure, similarly to hydrogen, forms strong chemical bonds with both components of the alloy. This is indicated by the presence in the mass spectra of a large set of oxygen-containing emissions of positive and negative secondary ions with lanthanum and nickel, as well as oxygen-containing lanthanum-nickel cluster secondary ions. The formed oxide compounds have a three-dimensional structure and occupy tens of monolayers. Oxygen poisoning of the surface of the hydride-forming alloy LaNi5 can occur regardless of whether the surface of the alloy was clean from the very beginning or it was covered with a layer of hydrogen-containing chemical compounds.

Published: October 2023

Lead halide perovskites have attracted considerable attention as one of the most promising materials for optoelectronic applications. The structural, electronic, and optical properties of the cubic perovskite CsPbF3 were studied using density functional theory in conjunction with plane waves, norm-conserving pseudopotentials, and Perdew-Berg-Erzenhof flavor of generalized gradient approximation. The obtained structural parameters are a good agreement with the experimentally measured and other’s theoretically predicted values. The obtained electronic band structure revealed that cubic CsPbF3 has a direct fundamental band gap of 2.99 eV at point R. The calculated energy band gaps at the high symmetry points agree with the other available theoretical results. The GW method is adapted to correct the underestimated fundamental energy gap value to 4.05 eV. The contribution of the different bands was analyzed from the total and partial density of states. The electron densities show that Cs and F have strong ionic bonds, whereas Pb and F have strong covalent bonds. The optical properties of CsPbF3 were calculated using the density functional perturbation theory and Kramers-Kronig relations. The wide and direct bandgap nature and the calculated optical properties imply that cubic CsPbF3 can be used in optical and optoelectronic devices for high frequencies visible and low frequencies ultraviolet electromagnetic radiation.

The paper determines the technological regimes for obtaining GexSi1-x alloys by introducing germanium atoms into single-crystal silicon by the diffusion method. From the results of the study, it was found that the fundamental parameters of the formed GexSi1-x alloys differ from the fundamental parameters of the original silicon, in particular, the energy values of the silicon band gap change. Elemental analysis of the surface of the samples showed that the concentration of silicon (in atomic percent) was ~70.66%, germanium ~29.36%. It was assumed that on the silicon surface and in the front part, a thin layer of an alloy of a compound with a composition of approximately Ge0.3Si0.7 (0.5÷2 μm) would be formed. Analysis of the spectra (p shows that the spectrum contains peaks ~303 cm-1 and ~406 cm-1, corresponding to the Ge-Ge and Si-Ge bonds, respectively. It was also shown that GexSi1-x binary compounds are a new material for modern electronics, the possibility of creating properties on their basis in electronics was shown. It is proposed on their basis to create devices with new functionality and highly efficient solar cells.

Published: October 2023

Silicon doped with gadolinium and silver impurities were studied using a Renishaw InVia Raman spectrometer. Registration and identification of both crystalline and amorphous phase components in the samples was carried out. Some changes are observed in the Raman spectra of gadolinium-doped silicon samples compared to the initial sample. It has been experimentally found that an increase in the silver impurity concentration in gadolinium-doped silicon leads to a smoothing of the Raman spectrum, which indicates the formation of a more perfect crystal structure.
Exogenous application of gibberellic acid on lateral bud emergence in pineapple
propagated through stem cuttings
Authors: Valleser V.C.
Published: October 2023

The effects of gibberellic acid (GA3) on lateral bud emergence in pineapple stem is still
not known. Hence, this study was conducted. ‘MD2’ pineapple stems were sectioned into
vertical halves. The first half served as the control (untreated). Whereas the other halves
were soaked in 500 ppm GA3 for 2 hrs. The study was performed in two trials. Results in
both trials show that untreated stem sections produced lateral buds after one week. In
contrast, the GA3 treatment prevented the development of buds. In trial 1, only 2 out of 18
stem sections (11.11%) soaked in 500 ppm of GA3 produced buds after one week. In trial
2, GA3-treated stem sections failed to produce buds. The average number of buds
emergence per stem section and diameter of lateral buds were consistently better in
untreated pineapple stem sections. These findings implied that the exogenous application
of GA3 could prevent the emergence of lateral buds in the pineapple stem.
Citation Practices in Colombian Undergraduate English Teachers’ Academic Writing
Authors: Salazar Obeso Wilmar
Published: October 2023

Citation is a crucial rhetorical aspect that plays a fundamental role within academic writing and it is a problematic area for novice writers, especially nonnative undergraduate English   teachers. However, little is known about how these teachers cite in the theoretical framework chapters of their monograph. This articles aims at describing the citation practices in a corpus conformed by 22 theoretical framework chapters of monographs written by undergraduate English teachers (UETs) in Colombia. The analysis was constituted by the citation typology of Swales (1986,1990) and Petriḉ’s (2007) functional taxonomy of citations.  The results indicate that integral citation is the most used citation type in the corpus of UETs which depicts a simple for of citation. Related to functions, the attribution is highly dominant   in this corpus which entails an undergraduate English teachers’ limitation in the variety of function citation. This study can be used to raise awareness on nonnative undergraduate English teachers towards better citation practices in their disciplinary academic papers.

In recent years there has been a tendency in the Russian Federation to increase the area under rapeseed, the area of which is constantly expanding. Research on economic and biological evaluation of spring rape varieties and hybrids was carried out in one of the farms of the Kirov region. Promising varieties and hybrids were studied under comparative aspect in production conditions. The seeds field germination was studied, the safety of the plants by the time of harvesting was determined. The duration of interphase and vegetation periods of the promising varieties and hybrids of spring rape was estimated, the yield of their seeds was compared. Analysis of the productivity structure elements of these varieties and hybrids is presented. In the experiment spring rape varieties Heros, Campino, Yarilo, obtained under farm conditions and having appropriate quality documents, and the first generation hybrids Joy, Jazz, Hephaestus, Joker, Jerome, Jerry were sown. When assessing the duration of the vegetation period, it was found that all the samples by biological rhythms fit into the vegetation period of the Kirov region and belong to the medium-maturing group. Field germination of the studied varieties and hybrids on average during the years of the study ranged from 48.8 to 75.8%. On average for 2 years, the highest field germination was observed in the first generation hybrids Joker and Hephaestus (75.8 and 69.1%, respectively). Preservation of plants for harvesting higher than the control (84%), on average for 2 years was observed in the varieties Campino and Yarilo. In terms of seed yield, hybrids Jerry F1 (16.7 c/ha) and Joker F1 (16.2) and the variety Yarilo (16.3 c/ha) significantly outperformed the control (15.5 c/ha). Hybrids Joy (450), Joker (482) and the variety Yarilo (459) reliably surpassed the control (358) by the number of pods on one plant on average for 2 years.
Worker and Peasant Questions in the Journalistic Legacy of N.D. Obleukhov
Authors: Shakhmatov V. V.
Published: October 2023

This article summarizes the experience in the broadcasting and promoting among the general population the views expressed by the Russian conservative thought during the early 20th century on acute social problems, including the worker and peasant questions. As one of the most striking examples, N.D. Obleukhov’s article “Tsarist autocracy as a bulwark of public freedom and equality”, which was published in December 1915 in three issues of the right-wing daily newspaper “Russkoe Znamya” (‘Russian Banner’), is analyzed. The obtained results reveal that the beliefs of the rightwing Russian monarchists were based to a certain degree on democratic ideas, such as the demand for extensive public self-government to control the establishment and development of new internal class organizations, particularly those for workers and peasants, as well as for the abolition of the privileges of the ruling class. According to this system, the “tsarist autocracy” appears to be the only force capable of truly protecting the interests of the working people, while the proponents of the constitution, including social democrats, directly or indirectly promote the interests of the bourgeoisie. Furthermore, N.D. Obleukhov proposed some tactics to preserve and further advance monarchical ideas among workers and peasants – they were limited to “permissible and quite legitimate ways” without armed struggle. N.D. Obleukhov’s article thus shows that the Russian monarchists held a controversial position on the eve of the revolution: on the one hand, they opposed the administrative authorities and the ruling elite of that time, but, on the other hand, they grew distant from the common people because of their radical revolutionary ideology.
The Image of an Ideal History Teacher from the Recollections about the Russian School in the 1840s and 1850s
Authors: Kozina N. G.
Published: October 2023

This article discusses the teaching methods that shaped the Russian school in the 19th century. The image of an “ideal teacher” is analyzed based on the recollections of historians of that period. The dynamics of its features is explored on a historical time scale. The factors that forced its transformation and evolution are considered. The sources used include memoirs written between the 1860s and 1870s, as well as those published at the turn of the 19th–20th centuries. The first group of memoirs is characterized by the juxtaposition of the “old” and “new” history teachers who differed in their preferred “teaching methods”, moral beliefs, and attitudes to teaching. In the second group of memoirs, the trend to a negative view of the “old” teachers and the effectiveness of their methods is rejected, while the “young” teachers are criticized. The obtained results show that an “ideal history teacher” was endowed by the memoirists of the 1840s and 1850s with such new personal and professional qualities as: humanity, morality, “expertise” (a high level of scientific knowledge), as well as a sincere desire to awake students’ interest in what they are being taught and to help them become self-reliant in their reasoning.
Restructuring of Universities in the Middle Volga Region and New Forms of Work Organization in the 1930s
Authors: Khabibrakhmanova O. A.
Published: October 2023

This article examines the changes in the higher education system of Russia during the 1930s when the long-established educational system was transformed to meet the state’s demands. The Soviet state faced the problem of training and fostering highly qualified specialists to solve the problems of the country’s industrialization. For this reason, an extensive campaign was launched to create technical universities in the country. The Middle Volga region, where several technical universities were opened in a short time, played an important role in this process. Based on archival documents, the steps taken to build a new higher school are analyzed. Due to the state demand for the economy industrialization, new forms of work organization were introduced into the professional activities of professors and lecturers, in some cases either against their actual will or under pressure from the authorities. A close connection between science and production contributed to the emergence of new work formats that did not always “fit” into the academic environment. By the end of the 1930s, however, the Soviet state, which had set a clear course for the development of industrialization, defined technical specialization as a priority direction in the system of higher education.

Pseudoloma neurophilia (Pn), the causative agent of the most commonly reported disease of zebrafish, is a microsporidianparasite that confounds research by inducing behavioral and physiologic changes in zebrafish. Although a treatmentfor P. neurophilia has not been documented in zebrafish, albendazole (ALB) and fumagillin (FUM) have been used to treatmicrosporidian infections of other fish species. To investigate the efficacy of oral ALB and FUM in the treatment of Pn, weperformed a pilot study that demonstrated the safety and palatability of novel gel-based diets containing FUM or ALB inadult AB zebrafish. In a subsequent study, approximately 250 adult AB zebrafish (previously infected with Pn) were treatedwith these medicated diets for 4 wk. At 4 different time points (weeks 0, 5, 10, and 16 of the study), fish were euthanized andwhole-body qPCR was performed to assess Pn prevalence across treatment and control groups. There was no statisticallysignificant association between treatment group and Pn prevalence at any time point, although potential biologically relevantreductions in Pn prevalence occurred in the combination therapy group at weeks 5 and 16 and in the ALB group at week 5.Based on high-performance liquid chromatography analyses, the medicated diets contained less ALB and more FUM thanexpected, highlighting the importance of validating medicated feed concentrations to ensure safety, efficacy, and consistency.While Pn remains challenging to eradicate and control, results of this study warrant further investigation into the utility ofALB and FUM as potential treatments for this pathogen.

Published: October 2023

Hash-based signatures are one of the most promising classes of cryptographic schemes considered quantum resistant ones. The strength of cryptographic hash functions is one of the most important aspects of ensuring the security of hash-based schemes.

Since classical hash-based signatures require tracking the number of signatures used, they were considered to be stateful for a long time. The SPHINCS scheme overcome this limitation, subsequently refined to SPHINCS+.

The paper provides an assessment of the security of ES based on hash functions relative to side channel attacks.It also gives an analysis of recommendations for the use of one of the candidates of the NIST competition, based on hash cryptography - SPHINCS+, and conclusions about the feasibility of its use.

Coffee is a mainstay of the plantation sector which has long been a driving force for the economy in Indonesia which has export value. The still not optimal production of coffee in Indonesia has a lot to do with productivity. Factors causing the low productivity of Indonesian coffee include lack of mastery of Good Agricultural Practices (GAP) and Good Handling Practices (GHP), low-quality beans at the farm level, attacks by plant-disturbing organisms, old plants that are no longer productive and farmer institutions that are still weak. Seeing the conditions of the existing problems, the development of coffee businesses needs to be studied for the feasibility of the business. The method used in conducting a business feasibility financial analysis is Net Present Value (NPV), Internal Rate of Return (IRR), Net B/C Ratio, Gross B/C Ratio, R/C Ratio , Return Of Investment (ROI), Payback Period and Profitability Index (PI). The method used is literature study by conducting a review of ten journals related to research. All journals use Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Period calculations. Net B/C Ratio is used by eight journals. Profitability Index (PI) is used by two journals. The Gross B/C Ratio is used by the three journals. R/C Ratio and , Return of Investment (ROI) are only used by one journal. The results of this study are expected to be a reference in assessing the feasibility of the coffee business.

Kecemasan sosial timbul akibat intensitas perbandingan sosial yang tinggi dan diikuti dengan harga diri yang rendah pada remaja. Penelitian ini bertujuan untuk menguji peran mediasi harga diri dalam hubungan antara perbandingan sosial dan kecemasan sosial pada remaja yang tinggal di panti asuhan. Pelatian dilakukan pada 124 remaja yang tinggal di panti asuhan dengan usia 13-18 tahun. Instrumen penelitian menggunakan skala kecemasan sosial, Rosenberg Self-Esteem Scale (RSES) dan Iowa Netherland Comparison Orientation Measure (INCOM). Data diolah dengan analisis mediasi menggunakan program statistik JASP versi 0.14. Hasilnya, harga diri dapat berperan sebagai mediator terhadap hubungan antara perbandingan sosial dan kecemasan sosial pada remaja yang tinggal di panti asuhan.

New Brunswick has high rates of sexually transmitted infections and unplanned pregnancies among youth, indicative of high-risk sexual behaviours. Positive parent-child sexual health communication can help youth develop healthy sexual practices, though a lack of available resources to support caregivers in their role as sexual health educators for their children has been reported. This study investigated the current sexual health education practices and needs of parents, step-parents, and guardians to inform the development and/or adaptation of resources to support parents as sexual health educators. Parents, step-parents, and guardians were recruited via email, social media, and poster-based outreach ( N = 5,462). Using the “Ask Me Anything” survey containing 41 items, participants’ demographic characteristics, current sexual health education practices, and sexual health education needs were captured. Descriptive statistics analyzed demographic characteristics and survey variables. Most participants indicated that they were primarily responsible for children’s sexual health education and felt they had sufficient knowledge and comfort to provide it. Parents reported communicating about sexual health a moderate amount with their children and were ambivalent about their satisfaction with existing resources and the sexual health education provided in schools. One-third of participants expressed needing more resources to support school-based education and to identify age-appropriate topics. Understanding parental needs and attitudes regarding sexual health education highlights opportunities for improvement by provincial health authorities and school districts. Recommendations to support the development of resources to address the specific needs of New Brunswick parents and guardians are suggested.

COVID-19, which has become a pandemic is caused by coronavirus and led to severe acute respiratory syndrome. Its complication include respiratory incompetence, damage in the muscles of the lung and heart , problems in nervous system and kidney or death. One of the characteristic symptoms of COVID-19 is the low levels of oxygen in patients' blood, a condition known as hypoxemia. Patients with hypoxemia often show the following symptoms: coughing wheezing, difficulty in breathing, headache, feeling disoriented, cyanosis in which the skin, lips, or fingernails become blue colored, even though hypoxemia is diagnosed by some tests, such as analysis of blood gas and pulse oximetry, caution should be considered when pulse oximetry interpreted, because of shifting in the left-sided of the oxyhemoglobin dissociation curve. Hypoxemia causes acute respiratory distress syndrome, that includes inflammation and edema, leadings to impairment in the alveolar homeostasis, modification in the physiology of lung resulting in vascular thrombosis, endothelial inflammation and pulmonary fibrosis, therefore any tardiness in diagnosis and introducing proper treatment can led to mortal outcomes. In this review we present hypoxemia as one of the symptoms resulting from infection with COVID-19 infection, focusing on their types, causes and possible treatment for this condition.
Pulpit and Politics: Christianity in the Struggle for Good Governance in Nigeria
Authors: O. IJAOLA Samson , A. ADEROJU Matthew
Published: October 2023

AbstractChristian pulpits are vocal and powerful political platforms in most countries of the world today. Through diverse forms of oracular messages, Christian pulpits engage itself in state affairs and governance of Nigeria. From blatant or cautious prophecies to flagrant or stealth solicitations for political candidates and their parties, some pulpits immerse themselves in politics. Moreover, either with the view to compliment or disparage the pulpit, the diverse politically inclined pews and the public often argue on the boundary of Christian pulpits in politics. As the pulpit actors often claim a divine responsibility to guide the country in the political space, it is confronted with the poser, on where and how to draw the line between its spiritual mandate and political stewardship. It is against this background that this study seeks to examine the roles of Christian pulpits in the struggle for good governance in Nigeria. Adopting literal criticism, the study concludes that the roles of the pulpit can be well-defined in politics. In addition, it should not limit its contributions to politics, as long as good governance remains its primary concern.

Returnees, Institutions, and Networks
Authors: Benton William
Published: October 2023

This article explores the development of Beirut's innovation ecosystem in the context of its social composition, complementing popular narratives of informal power in Lebanon. Drawing on ethnographic research, this article explores the extensions of existing institutions and practices—how universities, banks, and diaspora returnees collaboratively developed a context for venture development. By focusing on diaspora returnee expertise as a key driver for innovation ecosystem founding, the article also qualifies a key element of Lebanese economic development—the loops of emigration and return immigration of Lebanese people and the resulting economic and managerial cosmopolitanism inherent in their involvement in their country's commercial and financial settings. The emergent innovation ecosystem is a function of existing Lebanese cultural and organisational tendencies.

La investigación expone el diseño de una cartilla de actividades desde el aprendizaje dialógico como estrategia didáctica para mejorar la comprensión lectora de los estudiantes de quinto grado. Se ubicó en el enfoque cualitativo, en el paradigma sociocrítico y en el método de investigación acción pedagógica. La investigación se desarrolló en tres fases: inmersión inicial, que contó con un diagnóstico con los docentes y estudiantes; elaboración e implementación del plan, aquí se diseñó y aplicó la cartilla titulada La lectura mediada por el aprendizaje dialógico, y proceso de evaluación de los logros, donde se realizó la aplicación de actividades complementarías para evaluar los niveles de comprensión lectora. Los resultados indicaron que las estrategias utilizadas por los docentes no concordaban con los principios del aprendizaje dialógico; el diseño de la estrategia y la aplicación de las tertulias literarias dialógicas demandaban la presencia de los educadores y estudiantes. Por otro lado, se evidenció que los estudiantes adquirieron competencias lectoras con mejoramiento en los niveles literal, inferencial y crítico, dado que fueron capaces de identificar los temas, reconocieron las ideas explícitas o sugeridas por el autor, relacionaron los significados de las palabras u oraciones con sus propias experiencias y conocimientos previos. Se concluyó que, el uso de las tertulias literarias dialógicas facilitó la oralidad y mejoró significativamente la comprensión lectora de los estudiantes, permitiendo la transmisión de opiniones y expectativas de su propia realidad.
Overview of breast cancerpatients and their prognostic factors treated in Baghdad teaching hospital/ oncology department in the year 2010
Authors: Al Naqqash Manwar A.
Published: October 2023

Background:The breast cancer is the most common non-skin malignancy in women and prognostic factors are important in predicting disease free survival and overall survival.Objective: To detect prognostic factors of breast cancer patients and study the correlation between these prognostic factors.Patients and methods: this is a retrospective study which included87 patients with breast cancer receiving chemotherapy in Baghdad teaching hospital/ oncology department in the year 2010. Prognostic factors were registered including: age, histopathological subtype, degree of differentiation, lymph node involvement, ER and PR, Her 2/neu and lymphovascular invasion.Results: Regarding breast cancer; 55(63.2%) of patients were early breast cancer as compared to32(36.8%)patients with locally advanced breast cancer.Regarding lymph node involvement 31(36.9%) of patients had N0,28(33.3%) had N1, 23(27.4%) had N2 and 2(2.4%) were with N3. Regarding degree of differentiation the most common type was moderately differentiated with 58(66.7%) followed by poorly differentiated with 23 (26.4%) and at last well differentiated tumors with 6(6.9%) patients. Infiltrative ductal carcinoma was the most common subtype other histopathological subtypes as infiltrative lobular carcinoma (13.8%) and medullary carcinoma (2.3%). Intraductal carcinoma were present in 23 cases (25.8%).ER was negative in 33% and PR was negative in 37.5% while the remaining cases shows positivity with different percentage scores.Cross tabulation between different prognostic factors ( tumor size, lymph node, degree of differentiation, lymphovascular invasion) were done and results were statistically not significant, regarding ER and PR showed strong significant correlation( p < 0.0005).between the two markers also significant correlation was found between lymphovascular invasion and lymph nodes involvement.Conclusion: breast cancer is the most common solid malignancy treated in Baghdad teaching hospital. Early stage breast cancer were more common than advanced breast cancer, ER and PR(good prognostic factors) were statistically correlated to each other so were lymphovascular invasion with lymph nodes involvement(bad prognostic factors).
