Authors: Aleksandrzak Tomasz , Zabielska Kamila , Gabruś Elżbieta 
Published: April 2024

Abstract
The paper presents the results of experimental and model studies of the pressure swing adsorption (PSA) process in a column with a zeolite 13X bed with a height of 0.5 m. The gas mixture consisted of CO2 (10–20%), N2, and H2O (RH 50%) in different ratios. As a result of the column tests, concentration, and temperature evolutions were obtained for each of the adsorption and desorption stages, which were used to determine the breakthrough and bed saturation times and other parameters important for the analysis of the column operation. A mathematical model of the PSA process for the separation of CO2 from the gas mixture was developed. The system of second-order partial differential equations was solved using Matlab software. The research focuses on adsorptive CO2 capture and shows the influence of water vapor and operational parameters on the quality of model validation.
Liquid-liquid two phase-system stabilized by tween 40 and 80 surfactants: multiparametric study
Authors: Murasiewicz Halina , Illienko Khrystyna 
Published: April 2024

Abstract
The purpose of this study was to investigate the impact of process parameters such as interfacial tension, type of surfactants, and their concentration on simple oil-in-water dispersion. Explored systems were prepared with 5% liquid paraffin oil and aqueous phase with emulsifiers Tween 40 of concentrations from 0.008325 mM to 0.025 mM and Tween 80 with concentrations ranging from 0.00375 mM to 0.011 mM. All systems were characterized in terms of their density and interfacial tension. In the next step analysis of droplet size distributions and mean droplet diameter was performed. The results showed that the size of paraffin droplets decreased as the concentration of surfactants grew. This trend is accompanied by decrease in the interfacial tension between phases. The correlation between mean drop size and the energy input and physical properties of both liquids was developed. The last step provides scientific evidence for the formulation of stable droplets of liquid paraffin.

يقصد بها الأحاديث التي يُعبَّر عنها بكلام غير مباشر ومن غير تصريح ،وقد ضمّنت دلالتها لذاتها أو لعارض فهي ما أشتبه معناه وخفي مرادهُ فهذا النوع من الأحاديث يعتمد على إشارات ِغير ظاهرة أو قائمة على الستر والكتمان ولها ابعاد نفسية واجتماعية تتعلق بالفرد، ثم بالجماعة وهذا ما اعطى لنصوصهم ابعاداً اجتماعية لأنَّ كل نص شكّل إشارة داعمة لتزيد من فاعلية النص وتمده بسياقات جديدة ومبتكرة بعيدًا عن السياق النصي.
ولا يقتصر حديث الإشارة على الألفاظ فقط بل كل ما يصاحبها من وسائل الاتصال غير اللفظي كأن يستعمل أعضاء جسمه للتواصل مع الآخرين، أي يتكلم بجسمهِ كما يتكلم بلسانهِ وهذا بدورهِ يساعد في تعيين المعنى، وكشف دلالات الاتصال وتفسيرها تفسيرًا مناسبًا فلغة الجسد مساعدة للفظ ومدعمة له، فحظيت الإيماءات بالعين بنصيبٍ وافرٍ فوردت الإيماءة بالعين وملحقاتها(الطَّرْف، النظر، الغمز، الحاجب، الوجه، التبسم،...) في اشعارهم فشكّلت اللفظ المحوري، فالشاعر لم يعد مضطرًا لتبرير معرفة ما. فداخل لغته خصوصية معينة، فهو يشير للغة أخرى ليعبر عن ثقافة مكونة من العلامات عبر اختلاق إشارات شعرية ،فالحديث الإشاري له ميزة تكمن في أنه يمنح نفسه للتأويل ويدعو إلى ضرورته.

State-supported language strategies in Azerbaijan: promotion of Azerbaijani and multilingual initiatives.
Authors: Abdullayev Ramil Sahib 
Published: April 2024

The wealth of every independent and sovereign country is the abundance of language on its territory, in which the nationalities living there can freely use their languages. In addition to the State language, there are more than 15 languages spoken by ethnic minorities in the Republic of Azerbaijan. In addition to the languages of ethnic minorities, the population of the country uses other foreign languages, which are included in the group of world languages. The objects of research in this article are foreign languages and their relationship to the state language. The legislative acts adopted to regulate the language vector in the country are the subject of research. The author describes in detail and highlights the legislative bodies and government structures that play a crucial role in the development of language policy in the country. In the course of studying language policy, one cannot do without considering the following two main sociolinguistic terms: language regulation and language planning, which are of the nature of state or social impact on the functioning or development of languages in the state. The author mainly used the theoretical method in the study of the article, and also conducted a general analysis of the data. The conclusions are based on legal methods, as well as sociolinguistic methods (statistical and expert assessments). The necessary information in the field of the current language policy in the country was obtained during the analysis of legal documents. Foreign languages of global importance are in great demand among young people, increasingly studying these languages, they delve into the origins of this language, study the history of this country and through this prism the phenomenon of acculturation through language is observed. The author considers in more detail the status of the state language both de jure and de facto, and also considers in detail the position of the most widespread foreign languages in the republic. The language reforms carried out in the Republic of Azerbaijan mainly serve to strengthen the role of the Azerbaijani language as the state language and have the character of linguistic purism. Despite the ongoing reforms in the field of strengthening the state language, we are also considering a balanced language policy with regard to other languages existing on the territory of the Republic of Azerbaijan, the purpose of which is to preserve linguistic pluralism.

Abstract
Low-permeability laminated reservoirs have been a challenge for accurate characterization, more so when realtime decisions are critical for operations. Innovative and automated logging-while-drilling (LWD) measurements have come a long way to address this challenge. This work presents a study from the Alaska North Slope where two sections of a well were drilled with nuclear magnetic resonance (NMR) and bore-hole images (BHI) in conjunction with triple combo well-logs to characterize the challenging reservoirs.
In this study, the traditional measurements were supplemented with the new generation nine wait-time LWD NMR measurement as well as high-resolution LWD images. Realtime streaming of both NMR and image logs enabled by innovative data compression methodology resulted in automated answers as the intervals in the subsurface were getting drilled. Realtime porosity-distributions were made available with associated answer products of bound and free fluid volume and permeability of the thin sands, validated with realtime borehole images. The data were processed using a rate of penetration (ROP) aware 2D inversion (T1 and T2) to correct for any logging speed effects.
Subsequently, to fully unlock the potential of the acquired nine wait-time NMR data in conjunction with the other measurements, special methodologies were employed including "Factor Analysis" using a parallel analysis-based application and Viscosity Transforms based on empirical relations. These techniques enabled a comprehensive analysis and revealed a degree of variability in fluid viscosity along the drilled section, hitherto not understood. This variability is considered crucial for making informed completion decisions.
It is important to note that such analysis would not have been possible earlier during drilling, enabling realtime decisions in thin beds. Integration of new technology LWD NMR with borehole images revealed critical insights for development of low-permeability laminated reservoir, validated with core data.

Перспективным источником обогащающих ингредиентов являются ягоды дикорастущих растений и про- дукты их переработки. Являясь ценным источником макро- и микронутриентов, они способны выполнять определен- ную технологическую функцию при формировании пищевых систем. Исследованы функциональный состав и кислот- ные свойства высушенных и измельченных выжимок ягод шикши, брусники и клюквы, полученных как вторичный продукт низкотемпературной технологией сока прямого отжима. Спектрограммы исследованных образцов показали сходство функциональных составов. Основу высушенных образцов выжимок ягод составляет целлюлоза и ее произ- водные. Идентифицированы кислородсодержащие соединения с карбоксильными и сложноэфирными группировками, а также азотсодержащие вещества с амидными и иминными связями. Установлено более высокое содержание карбоно- вых кислот, карбонильных соединений и сложных эфиров в выжимках ягод шикши. Наибольшей кислотностью среди исследованных образцов обладают выжимки клюквы, 86,7% кислотности которых обусловлено наличием водораство- римых карбоновых кислот и соединений, проявляющих кислотную активность. Выжимки шикши и брусники близки по общему содержанию кислот. Однако при набухании выжимок ягод шикши в воде кислотность раствора лишь на 72,7% формируется за счет водорастворимых кислот. Результаты исследования позволили разработать рекомендации по ис- пользованию выжи мок из ягод дикорастущих растений в технологии пищевых систем, преимущественно кондитерских.
Berries of wild plants and products of their processing are a promising source of enriching ingredients. Being a valuable source of macro- and micronutrients, they are able to perform a certain technological function in the formation of food systems. The functional composition and acidic properties of dried and crushed pomace of shiksha, lingonberry and cranberry berries obtained as a secondary product by low-temperature direct-pressed juice technology have been studied. Spectrograms of the studied samples showed a similar functional compositions. The basis of dried samples of berry pomace is cellulose and its derivatives. Oxygen-containing compounds with carboxyl and ester groups, as well as nitrogen-containing substances with amide and imine bonds have been identified. Cranberry pomace has the highest acidity among the studied samples, 86,7% of the acidity of which is due to the presence of water-soluble carboxylic acids and compounds exhibiting acid activity. Pomace of shiksha and lingonberries are similar in total acid content. However, when the pomace of shiksha berries swells in water, the acidity of the solution is only 72,7% formed due to water-soluble acids. The results of the study made it possible to develop recommendations on the use of pomace from berries of wild plants in the technology of food systems, mainly confectionery.

This work aimed to map the Permanent Preservation Area (PPA) along the Mumbuca stream located in Monte Carmelo - MG. The determination of irregular occupation areas, as well as the mapping of land use and occupation, were obtained from the classification supervised through the SAS Planet computer program. In the Mumbuca stream PPA area, 64.43% were occupied by vegetation, 22.17% of urban use, and 13.39% by water. The initial section of the PPA that passes through the city center, was responsible for most of the irregular occupations in the area of permanent preservation, being that 21,02% of the 22,17% of the urban use, was located in this region. The rest of the PPA, which corresponded to about two-third of the total area, had only the remaining 1.15% of irregular occupations in the permanent preservation area.
