Role of Dietary Fiber in the Correction of Gut Microbiocenosis Disorders Against the Background of Antibacterial Therapy
Authors:   Central State Medical Academy of the President of the Russian Federation, Ardatskaya M.D.
Published: December 2021

Antibiotic-associated gut microbiocenosis disorders develop on average in every third patient in the form of both mild disorders and severe life-threatening conditions. The negative impact of antibacterial agents on the gut microbiota causes a decrease in the number and species diversity of microorganisms that produce butyric acid. Low concentrations of butyric acid can often induce inflammatory and atrophic processes of the gut mucosa, the water-electrolyte balance regulation disorders and, as a result, the gut motility and functions disorders. Long-term gut microbiocenosis disorders themselves can cause the development of the disease and in future, they become factors of its progression, thereby launching a whole cascade of new pathological processes. The article analyzes a representative clinical data published in authoritative international magazines from 1990 to 2020, indicating the effectiveness of the dietary fiber (DF) management for the correction of gut microbiocenosis disorders caused by antibacterial drugs intake. Partially hydrolyzed guar gum, registered in our country under the trade name “OptiFiber”, due to its effects such as the gut regulation, abdominal pain reduction, flatus and bloating reduction, increase the resident gut microflora amount and its metabolic activity, helps to restore and maintain of the gut eubiosis. Conclusion. “OptiFiber” can be administered for a long-term intake in order to increase the effectiveness of antibiotic therapy for various infectious diseases, as well as for the correction and prevention of gut microbiocenosis disorders associated with antibacterial drugs intake

In March 2020, an outbreak of a new coronavirus infection COVID-19 occurred in Russia. During a pandemic, patients do not always have the opportunity to receive full-time medical care. It became necessary to choose other methods of communication "doctor-patient" to solve the problems associated with the need to maintain the availability of medical care for patients with IBD. The progressive nature of the course of ulcerative colitis and Crohn's disease in some cases requires careful monitoring of the patient's condition. During a pandemic, doctors are advised to make wider use of the telemedicine resource. The article presents options for using distance counseling methods during the period of coronavirus restrictions

The relationship between the maximum deflections from a static uniformly distributed load W0 and the fundamental frequency of natural transverse vibrations of a round isotropic plate of linearly variable thickness with thickening to the edge under homogeneous conditions of support along the outer contour, depending on the ratio of the thickness of the plate in the center to the thickness along the edge, is considered. According to the results of the study, graphs of the dependence of the maximum deflection and the frequency of natural vibrations of the plate on the ratio t1 / t2 are constructed. It is shown that for round plates of linearly variable thickness at t1/t2<1.1 coefficient K with an accuracy of 5.9% coincides with the analytical coefficient for round plates of constant thickness. Numerical studies shows that when the ratio of the thicknesses on the contour and in the center is equal to two, the difference in the coefficient K, which depends on the relationship between the static and dynamic characteristics of the platinum, is about 25% for hinged support along the contour and up to 37% for rigid support. This indicates a more significant effect of uneven mass distribution for such boundary conditions.

In the Russian Federation, most low-melting clays used in the production of ceramic bricks have a low content of aluminum oxide (Al2O3=12-15%). With such a low content of aluminum oxide in clay materials, it is impossible to obtain bricks of grades M150 and higher from them. For the construction of load-bearing walls of the lower floors of high-rise buildings (15 floors or more), ceramic bricks of the M150-M300 brands are required. In such clay materials, to obtain earthquake-resistant bricks M150 and higher, it is necessary to introduce a thinning agent containing A12O3>50%. Taking into account the reduction of reserves of traditional high-alumina natural raw materials, it is necessary to find new ways to replace it with various types of waste. The experience of advanced foreign countries has shown the technical feasibility of this direction and its application as a tool for protecting the natural environment from pollution. In this paper, instead of natural traditional desiccants, it is proposed to use slag from the smelting of carbon-free ferrochrome containing A12O3=55.8%. As a clay material, substandard beidellite clay was used, which is not suitable for the production of ceramic bricks without thinners. A ceramic earthquake-resistant brick M125-M175 was obtained on the basis of slag from the smelting of carbon-free ferrochrome and substandard clay in the temperature range of 1050-1100oC

Arunachal Pradesh is rich with networks of drainage systems with enormous wild fish diversity due to varied climatic and topographical features. Most of the streams harbour very alluring small indigenous minnows, loaches, catfishes and barbs that have hardly been exploited for the ornamental fish market. If these aquatic resources are sustainably utilised as a trade commodity, then the pattern of livelihood of the local populace may be uplifted economically. The present investigation was undertaken to establish the market potential of certain indigenous ornamental fishes of Arunachal Pradesh. The survey was conducted during 2019–2020 for 6 months (October–March) based on the feasibility of accessible collections. A total of 52 ornamental fish species under 6 orders and 15 families were documented and collected during the surveys in various streams and rivers. The collection showed that 4 species namely Balitora brucei Gray, 1830, Aborichthys kempi Chaudhuri, 1913, Schistura devdevi Hora, 1935, and Neolissochilus hexagonolepis (McClelland, 1839) were recorded under near threatened; Lepidocephalichthys arunachalensis (Datta & Barman, 1984) and Botia rostrata Günther, 1868, under endangered and vulnerable categories, respectively as per International Union for Conservation of Nature (IUCN) status. The species documented exhibiting natural ornamental features herein considered an indigenous ornamental fish (IOF) for depicting their market demand showing the minimal price of each individual species towards the development of organised trade in Arunachal Pradesh.

Palinustus waguensis Kubo, 1963, is the deep-sea Japanese blunthorn lobster belonging to the Family Palinuridae. It is a species that has been rarely reported, living in rocky habitats on deep-reef slopes at a depth of 100–250 m. An estimated catch of 100 kg of P. waguensis consisting of 113 males, 54 females, and 23 berried lobsters were collected during the first fortnight of January 2019 from the multi-day shrimp trawls operating off Sakthikulangara, Kerala, India. The mean total length was recorded as 112.3 mm in males, 102.6 mm in females. The parameters of the length-weight relationship were estimated as, a = 0.041, b = 2.84 for males and a = 0.05, b = 2.86 for females, which were not significantly different (P > 0.05, r2 > 0.90) between the males and females. The relative condition factor (K) in the males and females of P. waguensis ranged from 2.07–4.96 and 1.87–3.86, respectively, attributing to the better feeding efficiency in males. Food and feeding analysis revealed the dietary content as fish (53 %), crab (23.5 %), shrimp (7.8 %), digested matter (11.6 %), and foraminifera (4 %). Feeding intensity analysis about the fullness of the stomach showed the specimens bearing full stomachs (11.3 %), three-fourth full (9.9 %). Length at 50 % maturity (Lm50) was 96.9 mm. Gonado-somatic index (GSI) ranged from 3.39 to 8.13. The present study forms the first report on the biology of the deep-water Japanese blunthorn lobster, P. waguensis from India.

Language undergoes some changes over time. These changes contribute to the development of the language. Tamil Grammar texts including Agathiyam, Tolkappiyam, Yapparungalam, Yapparungalakarikai, Purapporul Venpamalai which appeared in Tamil have been grammarized according to the Tamil tradition. However, Veerasozhiyam, which appeared in the 11th century AD, is a slightly different grammar text from this tradition. In particular, the Sanskrit language is written following the grammatical tradition. The author of this text, Ponparri Kavalar Puthamithranar, has written with the thought that Sanskrit Language mother for all tamil words. This Text has five Chapters: Eḻuttu, col, poruḷ, yāppu, alaṅkāram. The comprehensive authority of this Text is the authority to say.

Published: December 2021

The problems encountered in the production of the lentisk trees, which are one of the important endemic plants of our country have led to the use of biotechnological methods. In this research for this purpose, the TCL (Thin Cell Layer) technique was consideredto investigate of in vitro regeneration potential of expants used for production of lentisk. Firstly, the leaf, node and stem parts of the plant were cut by TCL technique and these explants had been cultured in semi-solid MS media supplemented with 2,4-D and KIN at different concentrations (0.1, 0.2, 0.5 and 1.0 mg/L). The highest callus formation percentage was 100% in transverse stem layers and longitudinal node in MS media including 1 mg/L 2,4-D and 1 mg/L KIN. The lowest callus regeneration ratios were found as 26.67% for three explant types (transverse leaf, transverse stem, longitudinal node). Due to the high rate of darkening in regenerated calli, these were transferred primarily to semi-solid media containing different antioxidants (ascorbic acid, citric acid, PVP, active charcole) and after that culturedin liquid media containing different plant growth regulators (IAA, KIN and BAP) to induced somatic embryogenesis. Later, the calli were encapsulated to prevent darkening and the nurse technique was applied with Aloe vera L. and Gossypium hirsutum L. calli as a different application. As a result of all these trials, somatic embryogenesis didn’t occur, but darkening ratio was reduced to 6.67%.
Endüstride Yaygın Olarak Kullanılan Asit Çözeltileri İçinde AA5754 Yüzeyinin ve Korozyon Davranışının İncelenmesi
Authors: KARACA Erhan , ALKAN Engin
Published: December 2021

Çeşitli uygulama alanlarında elektrolit olarak kullanılabilecek borik asit (H3BO3), tartarik asit (TA), okzalik asit (H2C2O4), hidroklorik asit (HCl), hidroflorik asit (HF) ve tetrafloroborikasitin (HBF4) sulu çözeltileri içinde alüminyum 5754 alaşımının (AA5754) korozyon çalışmaları gerçekleştirilerek ortamdaki asit niteliğinin aliminyum oksit oluşumu üzerine etkisi birbiriyle karşılaştırılarak incelenmiştir. Asitlerde bekletilen AA5754 yüzeyi XRD, XPS, AFM ve profilometre yöntemleri ile karakterize edilmiştir. XRD sonuçları Al2O3 oluşumunu gösterirken XPS sonuçları bu oluşumun doğrulanmasının yanında spektrumda B, O, C, Cl ve F piklerinin gözlenmesi nedeniyle asitlerin yüzeye adsorblandığına işaret etmiştir. AFM ve profilometre görüntülerinden H3BO3, TA ve H2C2O4 ortamlarında elde edilen oksit tabakalarının HCl, HF ve HBF4’dekilere göre daha düzgün topografyaya sergilediği belirlenmiştir. Tüm asitler karşılaştırıldığında H3BO3 ortamında en düşük pürüzlülük değerlerine (24.28 nm) sahip, homojen ve en kalın (15.4 nm) oksit filmin oluştuğu belirlenirken HBF4 ortamında tam tersidir (sırasıyla 99.44 nm ve 0.64 nm). AA5754 numunesinin korozyon davranışı asit çözeltileri içinde OCP, Tafel ve EIS ölçümleri ile incelenmiştir. Buna göre HBF4, HF, HCl, H2C2O4, TA ve H3BO3 sıralamasıyla OCP değerleri pozitif potansiyellere kaymakta, ikor değerleri azalmakta ve Rct değerleri artmaktadır. AA5754 numunesi HF ve HBF4 ortamlarında diğerlerine göre çok farklı bir korozyon davranışı sergilediği gözlenmiştir. Bunun nedeni HBF4’ün sulu ortamda kısmi ayrışması sonucu üretilen HF sayesinde yüzeyde AlF6-3 kompleksinin oluşumu ile çözünmenin daha fazla gerçekleşmesi olmalıdır. Tersine, H3BO3'te ortaya çıkan oksit tabakası, korozyona karşı en etkili yüzeyi sağlamıştır, çünkü diğerlerine göre zayıf asidik karakteri (pKa = 9.27) nedeniyle çekirdeklenme ve ardından pasivasyon çok hızlı gerçekleşmektedir.

Nükleer enerji, kesintisiz güç sağladığı için yenilenebilir enerji kaynaklarına göre geçerli bir alternatif oluşturmaktadır. Nükleer enerjinin ticari kullanımı ise nükleer reaktörlerde gerçekleşen kontrollü fisyon reaksiyonu yoluyla gerçekleşmektedir. Bu çalışmada, fisyon reaksiyonunu tetikleyen nötronlar çabuk ve geciken nötronlar olmak üzere ikiye ayrılmıştır. Süperkritik bir reaktör için, iki-nokta kinetik model numerik ve iteratif olarak çözülmüştür. Reaktivitenin lineer olarak arttığı durum için çekirdek, reflektör ve geciken nötron sayıları ilk değerler seçilerek zamanın fonksiyonu olarak hesaplanmıştır. Sonuçlarımız, artan geciken nötron oranı 'nın çekirdek ve reflektördeki nötron sayılarının üstel artış trendini kırdığını göstermektedir. =0.5 değerine ulaşıldığında çekirdek ve reflektördeki nötron sayıları stabilleşmekte, >0.5 bölgesinde ise asimptotik olarak sıfıra yakınsamaktadır. Geciken nötronlar β<0.5 iken üstel olarak artarken, =0.5 olduğunda lineer olarak artmaktadır. >0.5 olduğunda geciken nötron sayısı sıfırdan farklı bir değere asimptotik olarak yakınsamaktadır. Bu şekilde, geciken nötron oranını artırarak süperkritik bir reaktörde fisyon reaksiyonunun kontrol altında tutulabileceği gözlenmiştir.

Since the coronavirus pandemic hit Indonesia, tourists have become more careful when doing tourist activities. Natural or outdoor tourist destinations are assumed as safe and preferable destinations because they have the lowest risk of coronavirus transmission. One of the activities that can be done in natural or outdoor tourist destinations is camping. Using the AIDA (Attention, Interest, Desire, and Action) Model, this research was conducted to determine how much tourists are interested in camping, especially in South Bandung, West Java, Indonesia, as it has many natural tourist destinations with camping areas. This study uses a quantitative descriptive method, frequency analysis techniques, and scoring analysis. Samples were taken using a stratified random sampling technique to 111 respondents. Respondents are tourists who know or have visited one of the three natural tourist destinations in South Bandung, used as samples, namely Mount Puntang, Ranca Upas, and Rancabali. The results show that tourists are quite interested in camping as an alternative tourism activity during the coronavirus pandemic. However, they have some limitations or prerequisites in visiting the camping area during these uncertain times.

El presente artículo explora las representaciones sobre el movimiento social contra la dictadura chilena en la obra Tengo Miedo Torero (2001) de Pedro Lemebel. Considerando las potencialidades que tiene el análisis de las obras de arte para el abordaje de fenómenos sociales y la progresiva inclusión de la dimensión emocional en el estudio de los movimientos sociales, el análisis muestra que la novela de Lemebel integra representaciones del movimiento social contra la dictadura cercanas a la Nueva Historia Social, que incluye la descripción de escenarios de marginalidad, cesantía, juventud, represión, entre otras representaciones. Por otro lado, las emociones integradas en la narrativa de Lemebel (indiferencia, miedo, valentía) permiten abordar en mayor profundidad la etapa dictatorial chilena, explorando en dichos constructos emocionales que tradicionalmente las corrientes historiográficas no atienden.
El grupo político de las revistas Militancia Peronista para la Liberación y De Frente con las bases peronistas (1973-1974): una experiencia editorial y militante
Authors: Stavale Mariela
Published: December 2021

El presente artículo se concentra en la experiencia del grupo político que publicó las revistas Militancia peronista para la liberación y De frente con las bases peronistas, entre los años 1973-1974. Nuestra intención es, por un lado, reflexionar brevemente sobre el desafío teórico metodológico de trabajar con revistas político-culturales que devienen objetos de estudio y, por el otro, colocadas en la perspectiva de la nueva izquierda, reconstruir los orígenes del grupo político que se conformó en torno a las revistas, para identificar ideas-fuerza que surcaron los espacios de experiencia previos y compartidos y que permiten dar cuenta de cambios y continuidades en el proceso de transformación de su identidad peronista.
THE RELATIONSHIP BETWEEN COMPETITIVE INTELLIGENCE PROCESSES AND HOTELS' PERFORMANCE: EVIDENCE FROM MALAYSIA

Published: December 2021

Competitive intelligence (CI) is a proven systematic process used to improve an organization's competitiveness through the systematic collection, analysing, and communication of information to decision-makers. However, there is still ambiguity about the impact of each process of competitive intelligence process (CIPs) on performance, particularly in the hotel industry in a developing country like Malaysia. Thus, the purpose of this research is to detect the level of CIP practiced in Malaysian hotels, as well as to investigate the impact of each process from the CI processes (planning and focus, gathering, analysis, and communication) on the financial and non-financial performance of Malaysian hotels. A quantitative research design was adopted in this study. To obtain the necessary data for analysing the hypothesised model of the study, 505 questionnaires were issued to marketing managers in member hotels of the Malaysian Association of Hotels (MAH), and a total of 184 analysable questionnaires were gathered, with a response rate of 34.44%. The research data were analysed using partial least squares structural equation modelling. Despite that half of the responding hotels practiced CI informally, and many of these hotels began practicing CI five years ago, the study found that the level of CIP practice was high. Furthermore, the results indicate that the planning and focus, gathering, and analysis processes of CIP had a positive and significant impact on hotels' performance, while the communication process had a negative but insignificant impact on hotels' performance. Additionally, the results show that the planning and focus process is the most relevant, followed by the analysis processes, and finally the gathering process. These findings enrich those in positions of power like owners, managers, and practitioners, as well as academicians, with greater knowledge of the relationship and influence of CIPs on firms' performance, particularly for hospitality and tourism firms.

Published: December 2021

The higher demanding factor for residential and commercial units has seen an increasing number of STP maintained by IWK every year. This increasing number of STP has forced IWK to incur increased operating and maintenance costs. With a limited number of employees and a large catchment area, it has raised several issues and problems such as the issue of encroachment into the STP land. To overcome the issues and problems, strategic land development is needed where it is also a method in achieving sustainable development. This study used a qualitative method by analyzing the current work procedures or guidelines and government documents used by IWK such as the Federal Constitution of Malaysia, National Land Code, and Malaysian Sewerage Industry Guidelines. The findings of the study found that the function of IWK in sewerage land management for public STP and the former STP site is quite limited. Thus, a new procedure or guidelines need to be developed to improve these weaknesses. Based on the land issues faced by IWK, it shows that the strategic land development will be able to help IWK in the planning stages in the future effectively. While sustainable development can be achieved by IWK using a combination between the new land management model and GIS application. This new land management model needs to be combined and should include all the existing procedures or guidelines and be controlled by one unit only. GIS as the most powerful tool today seen can help IWK to manage all the matter related sewerage lands, such as finding the decommissioned STP site, selecting the new location for the Regional STP project, and selection of the new alignment for a property connection project. Indirectly, it can help IWK to reduce the cost of operation and maintenance, sewerage land issues, environmental issues, and others.

Urban design is part of the planning process that covers aspects of the physical quality of the environment and urban development relationships. Urban design is formed gradually along with the development of an area. Meanwhile, urban morphology is the expansion and shape of urban change, structure, and function of a city's fabric. Therefore, the purpose of this study conducted is to overview the urban morphology pattern and to determine the urban design elements that are being implemented in the Pekan Rembau. This study is conducted to identify the pattern of urban morphology and all the elements of urban design. The methodology applied for this paper is exploratory research in Rembau District, which consists of field observation and case study or field research of urban design and morphology toward creating sustainable development has been identified. The findings of this study are the urban morphology of Rembau City centre pattern as linear patterns were successfully built as planned to reveal their various functions. Then, according to Lynch’s theories of urban design elements, Pekan Rembau has identified five urban design elements. It locates urban morphology and urban design as products and processes within a framework based on the distinction between a few elements of urban. The paper concludes with suggestions of potential development and strategies.

Представлено результати експериментальних досліджень по запису мікрорельєфних структур сфокусованим лазерним випромінюванням з довжиною хвилі 405 нм на плівках неорганічних фоторезистів системи Ge-Se. Показано, що мікрорельєфні структури глибиною 100 нм можуть бути отримані на неорганічних фоторезистах складу GeSe3. Збільшення вмісту германію (досліджувався склад GeSe2) не дозволяє отримувати мікрорельєфні структури з глибиною рельєфу, необхідною для виготовлення дисків-оригіналів, які використовуються у виробництві DVD і BD компакт-дисків. Плівки з високим вмістом Se (GeSe8) характеризуються наявністю кристалічних включень і не можуть бути використані для отримання мікрорельєфних структур при запису інформації на диски-оригінали.
