Published: May 2021

From year to year, the role of Social Media has become increasingly important. In this context, public institutions in Romania have started to use social networks more and more often, in order to increase the interest of citizens for interaction through social media. Usually, online communication channels do not replace other means of communication, but offer the advantage of the large number of users who are increasingly active in these social networks. Also, public institutions maintain a close relationship with the media, given the fact that it can be a good channel of communication with citizens. Through this communication channel, they build a favorable image and make the activity of public administration transparent, which leads to an improvement in the relationship with citizens. Therefore, the relations of public institutions with the media are materialized through the organization of press conferences, through press releases or interviews with public administration leaders.
Language education and intercultural style
Authors: Hysenaj Valdet , Mujaj Hasan
Published: May 2021

Language education in the state of Kosovo is not given due attention during schooling at all levels of education. A major flaw in education at the country level. Language education is a broad, very broad and highly contemplative notion. It captures a long range of sub-factors of personality formation, so it is not just a matter of language, but also of other components of various social activities. However, the state does not deal with this major identity issue because the statesmen, ministers, deputies, etc. themselves. they do not know how to write no or no, nor to discuss according to the laws of the standard Albanian language. Very big surprise! For any criticism.

THE RELIGIOUS HIERARCHY AND SPIRITUAL LIFE OF JEWISH COMMUNITIES FROM THE EIGHTEENTH TO THE EARLY TWENTIETH CENTURIES
Authors: KARIMOV Jamolitdin
Published: May 2021

The Jews have come a long way in the historical process. It had an impact on all aspects of social and material culture related to daily life. Most of the Central Asian Jews reached high peaks and played a significant role in trade. Studies show that the Jewish community in Bukhara was well developed in the middle of the 19th century and had its orderly organizational structure. At the head of the administration was a man named Kalantar, and the chief rabbi, nicknamed Mullai Kalan, served as a representative for religious affairs. It also observed that from time to time, one person performed these two functions. Secular and religious administrations were closely intertwined but operated autonomously. The article analyzes the socio-religious structure of Bukharian Jews in the region, the tasks and activities of Kalantar, Mullai Kalan, Aksakal, Kaywani, and their role in the life of Jews. The article also contains information about the education system of Bukharian Jews, types of education, and the specialists who taught there. The article also includes the analysis of the written and oral literature of the Jews of Bukhara, individually written works, translations of religious texts and, the works of scientists who have made a great contribution to improving the literacy of the Jews of Bukhara.
ISSUES OF SOURCE STUDIES IN THE WORKS OF THE FOLLOWERS OF YASSAWI
Authors: ISHMUKHAMEDOVA Maryam
Published: May 2021

This article deals with the works of the poets of the poetry school called Poets of the Yassawiya School, founded by Ahmad Yassavi. As its content has come via manuscript sources, the work derives its core from manuscripts kept at the Institute of Oriental Studies named after Abu Rayhan Beruni under the Academy of Sciences of the Republic of Uzbekistan. The poets of this school are introduced through examples illustrating comparisons in their works. The research analyses the usage of their work in manuscripts and shows the growth in their number. We have tried to analyze and logically group those manuscripts retained in the institute fund we mentioned. Next, we looked through the writing methods used in various works and made some comparative analyses. The research touched on projects related to poetic storytelling written by the poets and offered several solutions to solve some issues related to their belongingness to this school. It showed the need for serious source study and linguistic analysis. Reflecting on the current problems facing the researchers of Yassawi’s work, we can say that the works of his followers require serious study, that the creation of a catalog of manuscripts is an urgent task. Currently, insufficiencies in research done over Yassawi studies are vivid, this creates a great need to initiate the stud over the works of their followers. Moreover, it illustrates an immense need to study each manuscript, their writing method, and the structure where their projects exist. Here, we did comparative analyses of some poetic text of stories in manuscripts attributed to Ahmad Yassawi from a methodological point of view for compliance with the style of Yassawi before including the results of the research. In the study of the work of Yassawi, there have been no cases of writing poetic stories. We have to take this issue seriously
and not rush to conclusions. With this regard, we compared the poems attributed to Yassawi to the works of his followers.

Высокое потребление энергии и ее стоимость увеличивается во всем мире, и наша страна не исключение. В настоящее время процессы динамичного развития возобновляемых источников энергии (ВИЭ) и сфера ветроэнергетики становится крайне актуальной. Возобновляемые источники энергии за последние несколько лет стали рассматриваться правительством Казахстаном как один из главных векторов развития энергетики, однако процесс развития ветроэнергетики имеет более хаотический характер. Большую тревогу вызывает масштабного загрязнения атмосферного воздуха вредными веществами, связанные работой теплоэнергетических предприятий. На сегодняшний день большинство электростанций в Казахстане работают на угольном топливе, что сопровождается выбросом опасных соединений тяжелых металлов и окиси углерода. В целях ее снижения рассмотрим перспективные ветроэнергетические технологии. Ветрогенераторы на базе горизонтально-осевых турбин – не единственное возможное решение для качественного преобразования энергии ветра в электричество. Есть и другие конструкции, иногда показывающие большую эффективность чем осевые турбины. Пример такой альтернативной конструкции – ветрогенератор с вертикальным ротором Дарье. Это необычное решение было предложено еще в 1931 году французским авиаконструктором Жоржем Дарье, который поставил перед собой задачу создать такой ветрогенератор, который бы работал при любом направлении ветра, при том не требуя строгой ориентации.

Published: May 2021

В статье рассматриваются исследования по разработке молотка для энергоемкого измельчения мясокостного сырья. Описывается разработанная конструкция молотка с острозубчатыми стержнями различной длины по двум рабочим поверхностям прямоугольного молотка, которая позволяет снизить энергоемкость процесса измельчения, повысить работоспособность устройства для измельчения, улучшить качество и интенсивность измельчения. Применение острозубчатых стержней молотков на 7–9 % увеличивает производительность мясокостной кормовой муки по сравнению с плоскими молотками, что связано больше всего за счет дополнительного раскалывания мясокостного сырья острыми зубьями стержней молотков, образующих интенсивное трещинообразование и раскол в частицах мясокостного сырья.

Приведены результаты исследования по математической постановке задачи принятия решений по управлению режимами работы установки каталитического риформинга ЛГ-35-11/300-95 Атырауского нефтеперерабатывающего завода в нечеткой среде и разработке эвристического метода ее решения. Для постановки и решения нечеткой задачи принятия решений по управлению объектом исследования модифицированы принципы главного критерия и Парето оптимальности для адаптации их работы в нечеткой среде. В результате получена многокритериальная задача принятия решений с несколькими нечеткими ограничениями. Разработанный эвристический алгоритм решения полученной нечеткой задачи основана на привлечение лица, принимающего решения, т.е. использования его опыта, знания и интуиции в процессе выбора решения. Полученные теоретические результаты по постановке и решению задачи принятия решений в нечеткой среде на основе эвристического подхода эффективно применены на практике. Оригинальность и новизна разработанного нечеткого подхода к решению задачи принятия решений по управлению режимами работы технологических установок заключается в том, что при постановке и решении задачи исходная нечеткая информация используется максимально. За счет этого обеспечивается высокая адекватность и эффективность принимаемых решений в нечеткой среде.

Published: May 2021

В настоящей статье авторы рассматривают примеры реализации токовых защит с использованием магнитоуправляемых контактов – герконов для электроустановок с комплектными распределительными устройствами (КРУ). Представленные защиты используются вместо или дублируют традиционные защиты, выполненных с использованием трансформаторов тока с ферромагнитными сердечниками и по сути являются ресурсосберегающими, а проблема создания устройств релейной защиты электроустановок от коротких замыканий без применения металлоемких трансформаторов тока (ТТ), неоднакратно отмечалась на международных конференциях по большим энергетическим системам (СИГРЭ). Само же создание таких устройств, начатое еще во второй половине прошлого столетия, остается актуальным и сегодня. Для повышения надёжности релейной защиты необходимо дублирование, как трансформаторов тока, так и защиты, от которых они получают информацию. Оптимальным решением построения устройств релейной защиты без ТТ является использование герконов, имеющих известные преимущества в сравнении с другими магниточувствительными элементами. За два десятилетия 21 века разработан ряд устройств, действие которых основано на срабатывании геркона, помещенного вблизи токоведущих шин электроустановки, предлагающих совершенно иной подход в реализации релейной защиты.

Oncogenic hypophosphatemic osteomalacia is a rare acquired condition (about 160 reported cases). The initial abnormality is the unregulated secretion of FGF-23 by small growth mesenchymal tumors. Fibrous dysplasia is a well-known cause of oncogenic osteomalacia, with the polyostotic form complicated in 50% of cases with severe hypophosphatemia. We report here the case of a 43 years-old man, admitted for diffuses bone pain and muscular proximal weakness, evolving for 2 years, complicated with a pathological femoral neck fracture. Lab studies found severe hypophosphatemia and an elevation of alkaline phosphatases with normal levels of serum calcium, 25OH-vit D3 and PTH. X-Rays revealed a diffuse bone demineralization with multiple vertebral fractures and a fracture of the femoral neck associated with multiple lytic lesions of the femoral diaphysis. Histological examination has concluded fibrous dysplasia. Main etiologies, such as iatrogenic causes and Fanconi syndrome, have not been considered. Treatment with phosphorus associated with 1,25OH-Vit D3 has been installed, associated with intravenous infusions of bisphosphonates.

Epidermodysplasia verruciformis (EV) is a rare autosomal recessive genodermatosis, characterized by an abnormal sensitivity to cutaneous infection for some types of human papillomaviruses (HPV) associated with a cellular immune deficit. It expresses the appearance of squamous macules and spread verrucous papules, with chronic evolution. In half of the cases, before the age of 30, appears preepitheliomatous lesions and squamous-cell carcinomas. Here we report the case of a patient having an EV complicated with squamous-cell carcinoma of the face.
Development of the pharmaceutical practice: an alternative to recovery from the crisis of the Algerian pharmacy
Authors:   Pharmacien libéral, 19 rue Chenaf Ammar – La Verdure – Batna 05000 – Algérie., Keddad Abdellatif
Published: May 2021

Pharmaceutical practice around the world has much changed. It progressed from simple delivery of medicines with advice during the last decade to a more active role including notions of responsibility for results of engaged therapies and the delivery of services. The world health organization (WHO), along with the International Pharmaceutical Federation (IPF), made a study of this problem in order to set up orientations that may allow the health ally professional who is the pharmacist, to better answer the care requirements of the population and better control the cost of drugs. In Algeria, where the pharmacist outcome is essentially indexed on the commercial margin, the issue is more specific. In fact, through a progressive reduction of the purchasing power of the pharmacists since 1998, the commercial activity has largely replaced the activity linked to public health, calling into question the utility of the dispensary pharmacist as a health actor in society. It would appear to be necessary, in the light of the Classification of the Activities for the pharmaceutical practice, established by the WHO and the IPF in 2006, entitled “Enlargement of the pharmaceutical practice”, to pave the ground for the pharmacy profile of tomorrow in Algeria. This pharmacy will allow to better serve the population’s health. This approach is illustrated with the Jordanian and the Swiss examples. This includes the optimization of the resources for health ally professionals by establishing a performance-related remuneration (PRR). This may allow the creation of a project that may precise the role and missions of the pharmacist in order to maintain the quality of life of the patient in the context of a multidisciplinary approach. This article is largely inspired by a working document intended to be released and tried on the ground and revised.

Authors:   Service de médecine nucléaire, CAC Batna, Batna – Algérie, Nezzar Adlen
Published: May 2021

Single-Photon Emission Computed Tomography-Computerized Tomography (SPECT-CT) is a new hybrid technique that offers new diagnostic capabilities in daily nuclear medicine practice due to the possible attenuation and/or scatters correction of the SPECT functional images and the availability of helpful anatomic information and that can be used as SPECT alone or as isolated CT. This technique not only allows acquiring fusioned anatomic and functional images at the same time but also, it greatly increases the sensitivity and accuracy of SPECT for particular clinical indications. Until now, SPECT-CT data have been mainly used in oncology and Cardiology, but now, many authors spread its use to many scan studies. SPECT-CT seems to increase diagnostic performances and to modify management of many patients. SPECT-CT the development will probably modify nuclear medicine practice and many studies have to be conducted to highlight consensual procedure guidelines. Daily practice shows indisputably the important contribution of this new nuclear adopted by physicians as by clinicians imaging technique.

Published: May 2021

Pharmacodynamic interactions are manifested by a change in pharmacological effect at the site of action. There may be a synergistic action, a potentiation or antagonism. Pharmacodynamic interactions are predictable and preventable since the mechanisms of drug action are defined in advance, the interaction drug-target is systematically described and various effectors and signal transduction systems are highlighted. Any time the plurality of molecular targets of the same drug should be considered when prescribing. The wide diffusion of pharmacological information and the updating of knowledge are then two tools to manage this kind of interaction.

Compatibility problems are frequently encountered in hospitals, particularly in intensive care units. Physico-chemical incompatibilities (PCI) may have different origins and several types. The result is inactivation of the active ingredient reacted training or derivative(s) more or less toxic. The issue of PCI is made complex, moreover, by the fact that the reactions involved may be influenced by many factors. This chemical problem becomes a public health concern because it poses a risk to the patient.

An approach towards an Improvement in performance of cook stoves has been a great challenge to scientists and researchers as biomass cook stoves are one of the basic needs of people living in rural areas. But due to household pollution by Traditional Cook stoves causes illness to people preparing for their regular meals near it. So, taking an initiative for Designing, Fabricating and Improvisation in the performance of Forced Draft cook stoves by placing proper Primary and Secondary holes in combustion chamber which gives better air distribution for proper combustion to get Lower Emission rates. Various experimentations are being performed on the basis of standard protocols i.e. BIS (Bureau of Indian Standards), VITA (Volunteer in Technical Assistance), EPTP (Emission Performance Test Protocol), WBT (Water Boiling Test) amongst which BIS had an upper hand and had very less uncertainty of errors due to which it is mostly being used in checking and improving emission performance of cook stoves for more efficient use with less chances of health issues. This paper consists of Design, Calculations and Constructional working of Forced Draft Biomass Cook stove and also the Burning rate Calculations were carried out to check fuel burnt rate.
Protective effect of casticin in myocardial ischemia/reperfusion injury in rats via attenuation of oxidative stress and inflammation
Authors: Ji Lei , Tian Zhen , Liu Yingying , Liu Min
Published: May 2021

Introduction

Myocardial ischemic/reperfusion injury is the main prognostic factor after myocardial infarction. However, by the time reperfusion is
achieved, the cardiac tissues have already undergone necrosis and initiated inflammation and oxidative stress. Therefore, the present study aimed
to evaluate the beneficial effect of casticin (CST) on myocardial ischemia/
reperfusion (MI/R) injury and to explore its mechanism of action.

Material and methods

MI/R injury was induced using 30-min left anterior descending coronary artery (LAD) occlusion followed by 4 h reperfusion.
CST was administered to rats before reperfusion. The outcome of CST was
determined according to various indices of oxidative stress, inflammation,
apoptotic genes and nuclear factor k-light-chain-enhancer of activated
B cells (NF-kB).

Results

The results suggested that CST causes significant improvement in
left ventricular systolic pressure (LVSP) and derivative of pressure over time
of maximal rate of rise of (usually) left ventricular pressure (± dp/dtmax) with
reduction of left ventricular end-diastolic pressure (LVEDP). It also reduces
increased ST segment together with restoration of the changes in RR interval and QRS complex. The histopathological analysis of cardiac tissue
further corroborated the effect of CST. It also causes improvement of the
antioxidant system by reducing malondialdehyde (MDA) level with increase
in superoxide dismutase (SOD) and glutathione peroxidase (GPx). The levels
of cytokines (TNF-α, IL-1β and IL-6) were also found to be reduced upon CST
treatment. The expression of NF-kB, inducible nitric oxide synthase (iNOS)
and BCL2-associated X protein (Bax) was found to be reduced in the CST
treated group together with an increase in Bcl-2.

Conclusions

Collectively, the results of the study demonstrated that casticin protects rats from MI/R damage possibly via attenuation of oxidative
stress, the inflammatory response and apoptosis. It was also shown to inhibit NF-kB and iNOS in western blot analysis.
Long non-coding RNA SNHG16 contributes to progression of carotid atherosclerosis by regulating miR-30c-5p/ADAM10 axis
Authors: Zhao Chunlan , Zhang Xiaopei , Hao Yugui
Published: May 2021

Introduction

Carotid atherosclerosis (CAS) is one of the main causes of cerebral infarction in the ageing population. Long non-coding RNA small nucleolar RNA host gene 16 (lnc-SNHG16) could promote the development of atherosclerosis. However, the mechanism of lnc-SNHG16 in CAS remains vague.

Material and methods

The expression levels of lnc-SNHG16, microRNA-30c-5p (miR-30c-5p) and disintegrin and metalloproteinase 10 (ADAM10) were detected by real-time quantitative polymerase chain reaction (RT-qPCR). Cell viability and migration were detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) and transwell assays, severally. The levels of interleukin-6 (IL-6), IL-β and tumor necrosis factor-α (TNF-α) were assessed by enzyme-linked immunosorbent assay (ELISA). Protein levels of spinal muscular atrophy (SMA), calponin and ADAM10 were examined by western blot assay. The binding relationship between miR-30c-5p and lnc-SNHG16 or ADAM10 was predicted by Starbase, then verified by the dual-luciferase reporter assay.

Results

Lnc-SNHG16 and ADAM10 were increased, and miR-30c-5p was decreased in CAS patient and oxidized low-density lipoprotein (ox-LDL)-treated human aortic smooth muscle cells (hASMCs). Lnc-SNHG16 silencing repressed cell viability, migration, inflammation, facilitated differentiation in ox-LDL-treated hASMCs. Moreover, mechanical analysis proved that lnc-SNHG16 improved ADAM10 expression by sponging miR-30c-5p.

Conclusions

Our data indicated that lnc-SNHG16 could regulate the progression of ox-LDL induced CAS model by the miR-30c-5p/ADAM10 axis, implying a potential therapeutic strategy for CAS
The underlying mechanisms of FGF2 in carotid atherosclerotic plaque development revealed
by bioinformatics analysis
Authors: Li Jian , Wang Haifeng , Dong Chenjie , Huang Junling , Ma Wenlin
Published: May 2021

Introduction

The purpose of this study was to explore the regulatory mechanisms of FGF2 on carotid atherosclerotic plaque development using bioinformatics analysis.

Material and methods

Expression profiles of 32 atheroma plaque (AP) and 32 paired distant macroscopically intact (DMI) tissues samples in the GSE43292 dataset were downloaded from the Gene Expression Omnibus database. Following identification of differential expression genes (DEGs),
correlation analysis of fibroblast growth factor 2 (FGF2) and DEGs was conducted. Subsequently, functional enrichment analysis and the proteinprotein interaction network for FGF2 significantly correlated DEGs were constructed. Then, microRNAs (miRNAs) that regulated FGF2 and regulatory pairs of long noncoding RNA (lncRNA)-miRNA were predicted to construct the lncRNA-miRNA-FGF2 network.

Results

A total of 101 DEGs between AP and DMI samples were identified, and 31 DEGs were analyzed to have coexpression relationships with FGF2, including 23 positively correlated and 8 negatively correlated DEGs. VAV3 had the lowest r value among all FGF2 negatively correlated DEGs. FGF2 positively correlated DEGs were closely related to “regulation of smooth muscle contraction” (e.g., calponin 1 [CNN1]), while FGF2 negatively correlated
DEGs were significantly associated with “platelet activation” (e.g., Vav guanine nucleotide exchange factor 3 [VAV3]). In addition, a total of 12 miRNAs that regulated FGF2 were predicted, and hsa-miR-15a-5p and hsamiR-16-5p were highlighted in the lncRNA-miRNA-FGF2 regulatory network.

Conclusions

CNN1 might cooperate with FGF2 to regulate smooth muscle contractility during CAP formation. VAV3 might cooperate with FGF2 to be responsible for the development of CAP through participating in platelet activation. Hsa-miR-15a-5p and hsa-miR-16-5p might participate in the development of CAP via regulating FGF2.

Authors: Jiao Luyan , Zhang Guoqing , Yuan Yi , Cao Ling
Published: May 2021

Introduction

The present study was to explore the correlation between cough variant asthma (CVA) and repeated episodes of mycoplasma pneumonia in children.

Material and methods

Multiple databases were searched for relevant studies, and the articles that eventually satisfied the inclusion criteria were included. All the meta-analyses were conducted with the Review Manager 5.2. To estimate the quality of each article, the risk of bias table was performed. Totally 1223 patients with CVA and 1437 patients with simple cough (SC) were included.

Results

Finally, 9 studies including 2660 patients were included, who eventually satisfied the eligibility criteria. The results of heterogeneity test suggested that the serum level of IgE (MD = 80.69, 95%CI [77.75, 83.62], P < 0.001; P for heterogeneity <0.001, I2 = 95%), eosinophil count (MD= 2.93, 95%CI [2.72, 3.13], P < 0.001; P for heterogeneity < 0.001, I2 = 71%) and the number of children with positive IgM (OR = 4.44, 95%CI [3.73, 5.29], P < 0.001; P for heterogeneity = 0.63, I2 = 0%) were significantly different. The value of IgE in CVA was higher than that in SC, eosinophil count in CVA was higher than that in SC and the number of IgM positive children in the CVA group was higher than that in the SC group.

Conclusions

This study demonstrated a correlation between cough variant asthma and mycoplasma pneumonia.
