النسب : تكمن أهميته عند العرب المسلمين كونه يمثل أساس الشرف ومناط الفخر ومن خلاله يعرف الصحيح من اللصيق ، ويٌعدَ علم الانساب من أهم العلوم التي وضعها الله سبحانه وتعالى حيث قال الله في كتابه الكريم يَا أَيُّهَا النَّاسُ إِنَّا خَلَقْنَاكُم مِّن ذَكَرٍ وَأُنثَىٰ وَجَعَلْنَاكُمْ شُعُوبًا وَقَبَائِلَ لِتَعَارَفُوا ۚ إِنَّ أَكْرَمَكُمْ عِندَ اللَّهِ أَتْقَاكُمْ ،وقوله سبحانه وتعالى ((وَهُوَ الَّذِي خَلَقَ مِنَ الْمَاءِ بَشَرًا فَجَعَلَهُ نَسَبًا وَصِهْرًا)) ،فالنسب مجلبة للعز ومدعاة للقوة والألفة والمحبة والتواصل  وبناءً على أهمية النسب والأنساب عند العرب قبل الإسلام وبعده أصبح علماً من العلوم الاسلامية وأخذ حصة لا يستهان بها في الكتابة التاريخية فكان أحد أهم الاتجاهات في الكتابة التاريخية للقرن الثالث الهجري ، فكان للأخباريين والرواة والنسابة الدور الكبير في كتابة الأنساب
مطلب الارض ومطلب الامن في كفتي ميزان العلاقات الحدودية العراقية الكويتية
Authors: Mohammed Saad Jassim
Published: August 2020

برزت مشاكل الحدود بين العراق و الكويت في اعقاب غزو العراق للكويت,  وما نتج عنه من قرارات دولية بتأثير الولايات المتحدة الامريكية التي قادت حربا دولية لإجبار العراق على الانسحاب من الكويت وكانت تلك القرارات تحت الفصل السابع و أجبر العراق على تنفيذها مرغما.

كان احدى هذه القرارات الدولية اعادة ترسيم الحدود بين البلدين و قد منح هذا القرار الكويت امتيازات كثيرة على حساب الاراضي العراقية المجاورة للكويت وهي غنية بالنفط (حقول الرميلة الجنوبي). كان ذلك القرار ذو طابع سياسي وأمني بالدرجة الاولى ولم يأخذ في نظر الاعتبار و بنفس الدرجة الجوانب التاريخية والقانونية, والاهم  هو الجانب الجغرافي عند تطبيق القرار.  لقد اعتمد  القرار على منح الارض لتحقيق او للوصول الى الامن للكويت الا ان هذا القرار, وبهذا الشكل, قد اسس لمشاكل و نزاعات ربما تنشأ مستقبلا .

من هذا المنطلق , يقع علينا كجغرافيين و مراقبين للأوضاع السياسية والأمنية بين البلدين ان يكون لنا دور في تقديم الحلول الواقعية و العقلانية  التي ترضي جميع الاطراف مما يؤدي الى حفظ الامن و السلام الاقليمي و الدولي خاصة وان البلدين يقعان في اهم و اخطر مناطق التنافس الدولي في العالم ( الخليج العربي). ختاما, نحن ندرك بان الارض تحقق الامن و لا يتحقق الامن بسلب اراضي الطرف الاخر.

(مُلَخَّصُ البَحث)

ما يتميّز به العصر الحديث هو التقدم الهائل في (تكنولوجيا) الاتصال، ومواقع التواصل الاجتماعيّ المتعددة الأنواع والأشكال، وقد ظهرت هذه الوسائل بوصفها منجزاً حضارياً أفرزته العقول العملاقة المبدعة، عبر (التكنولوجيا) المتطوّرة الفذّة، ووسائل الاتصال هذه لها آثار إيجابيّة عظيمة، وأخرى سلبيَّة.

هناك ثلاثة مليارات شخص حول العالم يستعملون مواقع التواصل الاجتماعي، أي ما يعادل 40 في المئة من سكان العالم. كما إننا نقضي في المتوسط نحو ساعتين يوميا في تصفح هذه المواقع والتفاعل من خلالها، وذلك وفقا لبعض الدراسات الحديثة. ويمكن القول إن هناك نحو نصف مليون تغريدة وصورة تنشران على الفيس بوك كل دقيقة (http://www.bbc.com ) ولأهمية الموضوع قام الباحث باعداد دراسة حاولت الاجابة عن تساؤل رئيس هو الى أي مدى يثق طلبة كلية الشرطة بما ينشر في مواقع التواصل الاجتماعي ( الفيس بوك ) وما هو تأثيره في سلوكهم الحالي ومستقبلهم المهني ، وفي ضوء مشكلة البحث أعتمد الباحث على المنهج المسحي ، إذ قام ببناء مقياس وتوزيعها على مجتمع البحث الذي يبلغ (170) مفردة ، وكانت ابرز النتائج ان (77.6%) من المبحوثين يرون ان الناشرين على موقع الفيس بوك يسعون الى نشر المعلومات والاخبار التي تتمتع بالإثارة والتشويق لاستقطاب اكبر عدد ممكن من المتصفحين من دون النظر الى مدى مصداقية هذه المعلومات والاخبار التي تنشر .
A Feminist Stylistic Analysis of Katherine Mansfield’s
Authors: Ibrahim Farah Hafedh
Published: August 2020

هناك اعتقاد دائم بأن النساء بشكل عام يعاملن بقمع ، وينظر إليهن على أنهن أقل من الرجال ويخضعن للتمييز الشخصي والمؤسسي. نظرًا لأن الأدب يعكس الطريقة التي يفكر بها الناس ويظهر العلاقة بين الخيارات اللغوية والمعاني التي تم تفسيرها اجتماعيًا ، يتناول هذا البحث قصة "الانسة بريل" لكاثرين مانسفيلد من خلال تحليل اسلوبي نسوي لمعرفة كيفية تمثيل الشخصيات النسائية. ويهدف أيضًا إلى استكشاف ما إذا كانت كاتبة النص المعني قامت بتعزيز أو تحدي الصورة النمطية للمرأة عن طريق النظر إليها على أنها أدنى من الرجل أو مساوية له. إن إجراء تحليل أسلوبي نسائي ، من خلال استخدام نموذج تحليل سارة ميلز (1995) ، ينطوي على توظيف ثلاثة مستويات من التحليل أي مستوى الكلمة ومستوى العبارة ومستوى الخطاب. ومن خلال تحليل القصة القصيرة المشار اليها تم التوصل إلى أن الطريقة التي يتم بها تمثيل النساء تتأثر اجتماعيًا بالمعتقدات السائدة بأن النساء سلبيات ، وخاضعات ، يعتمدن على الرجال، وأقل من الرجال وغير متساوين معهم.
BAHASA ARAB DI ERA DIGITAL: EKSISTENSI DAN IMPLIKASI TERHADAP PENGUATAN EKONOMI KEUMATAN
Authors: Muis Muhsin
Published: August 2020

As long as we hold fast to the Qur'an and the Hadith in every activity of our lives, there is a role for Arabic in it. No even exception in the economic field, especially those based on Islamic law. Although lately there have been various translations into several languages, even all languages on earth, but it cannot be denied that it requires an in-depth and comprehensive understanding of Arabic before carrying out any process of translation, especially the language of the two Islamic Shari'a sources uses diction or sentence structure which cannot be easily transliterated or interpreted. Thus, as long as Muslims in this world exist, Arabic language continues to exist as well and its impact on every activity of life will always be strong, including the matter of strengthening the economic welfare
The “Innocence of Muslims” in the US Media: An Analysis of the Media Discourses on Islam and Muslims
Authors: Iqbal Zafar , Khan Fazal Rahim , ur Rehman Haseeb
Published: August 2020

The release of trailer of ‘Innocence of Muslims’ generated a huge debate on free speech, hate speech and the representation of the Muslims and Islam in the Western media. This paper investigates these issues in detail by taking instances from the mainstream US print media. Some other interesting debates in the mass media like the identification of the filmmaker and denigration of the Muslims and Islam in historical context have also been undertaken in the paper. Discourse theory and social construction of reality by Schutz (1976) and Berger and Luckmann (1991) have been applied as theoretical framework to evaluate the relationship between mass media and social construction of reality, and to see as how the US mass media constructed the reality about the movie (trailer). Three major aspects were selected for analysis; viz., filmmaker(s) and their associates, issues concerning freedom of speech and expression, and the representation of the Muslims’ protesting against the YouTube clip and the ensuing violence in some Muslim countries.

Authors: Naveed Shagufta , Khurshid Muzammil , Azeem Muhammad
Published: August 2020

The objective of this study is to check the gender-wise awareness level and willingness regarding products and services of Islamic Banking in Pakistan. Islamic banking means a system in which banking operations and activities are defined by Islamic Jurisprudence.As Pakistan is a Muslim majority country, it is important to analyze the awareness level about Islamic Banking products and services. By using random sampling, a questionnaire was distributed to 300 men and women respondents from different cities of Pakistan to collect data. This study employed descriptive analysis and independent t-test to analyze the results.The study concluded that there is a lack of awareness of Islamic Banking products and services in both men and women.The study found that women exhibited a low level of awareness but they are more willing to move towards Islamic Banking products and services if the management of Islamic Banks properly guides and explains them the attributes of Islamic Banking products and services because they are keen toward religion as compared with men.
Role of Socialization Patterns in Adopting Rigid Sectarian Identities
Authors: Jamil Muhammad Faizan , Sohail Tayyaba
Published: August 2020

Religion is an essential part of individuals’ daily routine practices in the Pakistani society. People rigorously own and defend their particular religious beliefs in the extremely diversified population of the country. The induction of sectarian ideologies in the mindset of children begins with their early socialization. This process further develops with the passage of time and the mindset of children becomes extremely rigid. Sectarian rigidity advances the elements of disrespect and intolerance among the believers of adverse sectarian groups. This study was aimed to explain the role of socialization patterns (religious ideological orientation, cultural socialization and peer group pressure) in enhancing sectarian rigidity in the society. Survey research was conducted in two high ranking universities of Lahore (one government university and one private university). It was based on the responses collected from 250 participants who were selected through the application of simple ransom sampling technique. Two hypotheses were tested to evaluate the relationship and the predictive role of socialization patterns in enhancing the element of sectarian rigidity in individuals. The results of the current study revealed that there was a significant positive relationship between socialization patterns and sectarian rigidity after the application of Pearson product-moment correlation test. Furthermore, the results computed through multilinear regression analysis showed a significant and positive predictive role of socialization patterns in enhancing sectarian rigidity. Thus, religious ideological orientation, cultural socialization and peer group pressure influenced the behavior of individuals that generate rigid sectarian identities in the society.
Islamic Habitus in English Language Textbooks Produced by Boards in Pakistan
Authors: Khokhar Ashar Johnson , Muhammad Yaar
Published: August 2020

The textbook is an important and powerful tool used by the state to reproduce the social and cultural habits of a group, most often, of the majority group’s social and cultural imaginations. The habitus produces and instills the world-view about society, the social and cultural values that a state valorized and would like pupils to internalize and make it part of their world-view. This study analyzes the English textbook published by the state textbook boards (Punjab, Khyber Pakhtunkhwa, and Sindh) for the academic year 2018-2019 for pupils of classes four to eight. The textbook content was analyzed using the Qualitative Content Analysis method. The content of 15 textbooks was digitized (scanned and made readable) to electronically categorized the text into categories using Nvivo 12 Plus software. The analysis revealed that the content is focused on developing and promoting Islamic habitus through stories weaved around family, making it a core component of a Muslim country. The family members practiced Islamic values, social and cultural, not only through their everyday lives at home, in school, and at other public places but also within their community through the celebration of cultural and religious festivals. The textbooks presented the Prophet Muhammad (PBUH) and his family’s life as an ideal life to be lead by all, whether Muslims or non-Muslims. The textbook highlighted the ‘good,’ the ‘bad,’ valorizing the former and stigmatizing the latter to encourage pupils to develop an Islamic world-view. The textbooks fail to look into the micro-level national habitus, that is, portraying the habitus of its minorities, ethnic and religious, as the content did not integrate their habitus into the national habitus of Pakistan, making it the habitus of the majority. The current fast globalizing world needed to be presented to pupils a world-view, and this required, broadening the scope of textbook content to make it reflective of true Pakistani habitus aligned and rooted in the humane global world-view.
Epidemic of youth nicotine addiction? What does the National Youth Tobacco Survey 2017-2019 reveal about high school e-cigarette use in the USA? (Preprint)
Authors: West Robert , Brown Jamie , Jarvis Martin
Published: August 2020

Background: Between 2018 and 2020, the US Food and Drug Administration announced various restrictions on e-cigarette manufacturers in response to a perceived epidemic of e-cigarette use and nicotine dependence among high school students. The stimulus came from headline figures from the 2018 and 2019 National Youth Tobacco Survey (NYTS). We analysed e-cigarette use and dependence in the NYTS in relation to lifetime history of use of tobacco products.

Design and setting: Nationally representative annual survey of high school students 2017 to 2019.

Participants: 10,186 students in 2017, 10,991 in 2018 and 10,097 in 2019.

Measurements: Any use of e-cigarettes in past 30 days, frequent e-cigarette use (≥20 of past 30 days) and indicators of tobacco or nicotine dependence (strong craving in past 30 days; wanting to use within 30 minutes of waking) were analysed in relation to lifetime tobacco product use history, ranging from never use through to lifetime smoking of >100 cigarettes.

Findings: Past-30-day e-cigarette use increased from 11.7% in 2017 to 20.8% in 2018, and 27.5% in 2019. In 2019 it was reported in 13.3% of never tobacco users, 30.9% of those who had tried only a non-combustible product (OR 2.9, CI 1.9-4.5), and in 73.8 % of those who had smoked more than 100 cigarettes in their lifetime (OR 18.3, CI 8.4-40.1) Frequent use occurred in 1.0% of never tobacco users in 2018 and 2.1% in 2019. Among otherwise tobacco naive past-30-day e-cigarette users in 2019, 8.7% reported craving and 2.9% reported wanting to use within 30 minutes of waking.

Conclusions: While use of e-cigarettes in US high-school students increased sharply between 2017 and 2019, frequent use and signs of e-cigarette dependence remained rare in students who had never used tobacco.

Abstract. Purpose. The research is aimed at studying and substantiating the directions of improving the state planning system and adapting the methodology of its use to the trends of modern economic reality. Methods. The methodological apparatus of research on the stated problem is based on methods of economic and comparative analysis, expert assessments. Methodological aspects of the development of the state territorial plan for agricultural development are described. Results and practical significance. The article examines the features of the formation of the state planning system in the agricultural sector of the economy. The mechanism of forming a program-target approach in the national system of state planning is studied. The necessity of using state planning tools in the conditions of adaptation of the agricultural sector of the economy to the trends of turbulence in the world and national economy is substantiated. It is argued that the lack of effective scientific-based tools for the system of state regulation of the economy is becoming the main factor hindering the development of the agricultural production sector of the country. The results of the study show that in modern conditions, the use of state planning tools should be systematic, including macro-and microeconomic aspects. The conceptual provisions of the study and its practical conclusions can be used by economic entities to improve the quality of management decision-making, as well as by public authorities at various levels of management as a tool for scientific foresight and variant analysis to stabilize the agricultural sector of the economy in the new economic reality. Scientific novelty. The developed model of state territorial planning of development of agrarian sector of economy of Russia, presented the key elements of the state strategic planning: plans, forecasts, programmes and projects, and adapted to the new economic reality. The trends of the pandemic allowed us to emphasize once again the author's hypothesis that state planning is a tool for the progressive development of agriculture in modern conditions.

Transdisciplinary Collaboration in ESD Teacher Education Programs
Authors: Hoiß Christian
Published: August 2020

Putting Education for Sustainable Development (ESD) into effect will become a major task for the 21st century, particularly for future teachers who are expected to participate in ESD but whose studies often do not prepare them for this task. This article responds to the question how collaboration in teacher education can help bridge that gap and how it can contribute to the transdisciplinary demands of ESD. It assumes an essential role in enabling collaborative spaces of dialogue and transfer of knowledge between educators and students of all academic disciplines, schools, universities, local stakeholders, and CSO. This speciﬁcally includes perspectives from the Global South.

Presenting the certiﬁcate program “el mundo – ESD in university level teacher education” (LMU Munich) as an example for collaborative ESD practice, the article identiﬁes and presents four central ﬁelds of transdisciplinary collaboration in teacher education: content– related, institutional, and biography–affecting collaboration, as well as collaboration in pedagogical–didactic contexts.

La cartografía social y la educación para el desarrollo y ciudadanía global (EpDCG) comparten entre sus ﬁnes la perspectiva democrática y participativa, el compromiso con la reﬂexión y el diálogo sobre la realidad social, la comprensión de las dinámicas de poder, la orientación hacia el cambio y transformación cara cotas más altas de justicia social. Es por ello que se eligió la sala cartográﬁca como instrumento para mapear experiencias de EpDCG en Galicia. La intención es visibilizar estas experiencias a la vez que se crean redes de colaboración. Las dos salas cartográﬁcas puestas en marcha han permitido crear espacios de encuentro, deliberación y debate, que han tenido como resultado, tanto la propia construcción colaborativa de la sala, como la realización de un mapeo inicial de experiencias de EpDCG.

NECROPSY OF AN OLIVE TURTLE: Lepidochelys olivacea (Eschscholtz, 1829)
Authors: Furtado Gil Dutra , Silva Rute Cavalcante da , Oliveira Patrícia Aguiar
Published: August 2020

The necropsy is an action composed of several stages carefully organized and performed on a corpse, aiming to elucidate or confirm what happened to the animal, so that it would die. The autopsy performed on a turtle by the team of academics from the Veterinary Medicine course at UNINASSAU, was of great value in making it possible to better understand its cause of death. Many convalescent turtles are sent to specialized environments in order to have their health restored, but some unfortunately end up dying, due to the seriousness of their case. The necropsy is then performed to clarify, refute, confirm or even modify a diagnosis previously established. Each necropsy stage is performed with great responsibility, where the qualification of veterinary medicine students is of paramount importance for this specific purpose. The necropsy performed on this chelonian Lepidochelys olivacea, aimed to provide an active practice and present a range of scientific knowledge, which academics will deal with now or in their professional lives. The conclusion regarding the autopsy performed, revealed that the cause of death was due to a cranial laceration probably caused by a propeller of a motor boat.

A anatomia é o ramo da biologia que estuda as formas e estruturas dos organismos, sendo disciplina básica na formação de profissionais em todos os cursos nas áreas da saúde como a medicina, enfermagem, fisioterapia, medicina veterinária entre outras. O estudo da anatomia via de regra é associado por meio da administração de conteúdos teóricos e práticos em laboratórios especializados a partir de peças anatômicas, já o estudo da anatomia veterinária não difere em nada quando comparado a anatomia humana apenas que as peças estudadas são oriundas de animais mortos quer sejam in natura, conservadas, ou mesmo manequins e peças sintéticas. Nas escolas de educação básica tanto as de ensino público como as privadas têm se verificado um escasso conhecimento sobre ciências, pois muito pouco do que se é ensinado, é aproveitado, desta forma esse déficit de conhecimento e saberes provenientes do ensino prévio geram dificuldades nos discentes quando ingressos nas instituições de educação superior resultando em problemas na aprendizagem dos estudantes e até mesmo levando ao total abandono do curso por parte dos acadêmicos. Neste contexto que o uso da anatomia veterinária como instrumento pedagógico aparece nas escolas de ensino fundamental e médio, tendo em vista que a partir do momento em que o alunado tem um contato direto com peças anatômicas permiti uma maior absorção e fixação dos conteúdos ao serem associados com atividades práticas, desta forma compreendemos que por meio da inserção das aulas práticas de anatomia veterinária nas escolas conseguimos uma contribuição direta no processo educacional e aprimoramento do ensino-aprendizagem.
Intermediate Strain Rate Testing Devices
Authors: Bhujangrao Trunal
Published: August 2020

The existing experimental tests are mainly designed to study the mechanical response of materials at various strain rates. Many researchers performed the experimental test in tension, compression, and shear (with torsion test) over a wide range of strain rates. They found out that material exhibits an increase in yield stress as well as flows stress with an increase in strain rate. It illustrates that there is a need for experimental data to study the material behaviour over the full range of strain rates, from quasi-static to high strain rate test. Many special techniques have been developed to bridge the strain rate gap between quasi-static and high strain rate testing to provide a method for an intermediate strain rate test for engineering materials. Some researchers have tried to conduct intermediate strain rate tests with standard servo-hydraulic load frames. However, the results of such tests are not accurate. The problem is that during the experiment, the whole machine is not in static equilibrium. The inertial effect influences the experimental data. The records obtained from these machines are often noisy with large oscillation. therefore, the comprehensive review is given to describes the development and evolution of the existing intermediate strain rate testing devices which includes the working principles, some critical theories, technological innovation in load measurement techniques, components of the device, basic technical assumption, and measuring techniques. In addition, some research direction on future implementation and development of an intermediate strain rate apparatus is also discussed in detail.

Authors: Mancini Leonardo
Published: August 2020

Biomaterials derive either from nature or synthesized in the laboratory using chemical approaches utilizing metallic components, polymers, ceramics, or composite materials. They are often used and adapted for medical applications. A biomaterial is also defined as autograft, allograft, or xenograft used as a transplant material. In the last decade also tissue engineering and stem cells were deeply studied trying to make better autologous biomaterials ready to be used in regenerative procedures. Micrografts are a new concept of biomaterial, they are enriched of progenitor cells that are a particular type of stem cell excellent in enhancing the regenerative potential. Moreover, another advantage is the easy handling and tissue availability.
Ciguatoxins in Fish
Authors: Pasinszki Tibor , Lako Jimaima , Dennis Todd
Published: August 2020

Ciguatoxins are very potent marine neurotoxins, that accumulate to toxic levels in edible fish in certain circumtropical areas, and are associated with ciguatera fish poisoning worldwide. Ciguatoxins are produced by specific benthic dinoflagellate species, enter the marine food chain via herbivorous fish and invertebrates, and eventually biotransformed in herbivorous, omnivorous, and carnivorous fishes to more poisonous forms. Ciguatoxins cause risks to human health at very low concentrations. To decrease the risk of ciguatera fish poisoning, it is important to know fishing areas with low risk of ciguatoxins, as well as to test fish tissue for toxins before consumption. Modern laboratories are using several detection techniques, such as mouse bioassay, cell-based assays, receptor-binding assays, antibody-based immunoassays, electrochemical methods, and analytical techniques, to obtain information about the total toxicity of fish tissue samples, as well as to identify toxins and to determine the toxin profile. State-of-the-art ciguatoxin detection involves the combination of a cell-based assay or receptor-binding assay to screen the total toxicity and liquid chromatography coupled with mass spectrometry to confirm toxins and provide toxin profiles.

Although many preventive and treatment approaches have been proposed, cardiovascular disease (CVD) remains one of the leading causes of deaths worldwide. Current epidemiological data require the specification of new causative factors, as well as the development of improved diagnostic tools to provide better cardiovascular management. Excessive accumulation of adipose tissue among patients suffering from obesity not only constitutes one of the main risk factors of CVD development but also alters adipokines. Increased attention is devoted to bioactive adipokines, which are also produced by the adipose tissue. The retinol-binding protein 4 (RBP4) has been associated with numerous CVDs and is presumably associated with an increased cardiovascular risk. With this in mind, exploring the role of RBP4, particularly among patients with obesity, could be a promising direction and could lead to better CVD prevention and management in this patient group.

It is advisable to use two-phase heat transfer circuits (TPC) on spacecraft with high heat release in thermal control systems (TCS). TPC has many advantages over single-phase heat transfer loops. In such circuits, heat is accumulated and transferred in the form of latent heat of vaporization. TPC can transfer a much larger amount of heat per unit mass flow rate, the temperature of objects can be maintained almost constant throughout the heat supply area and close to the saturation temperature. Besides, all heat transfer processes occurring during boiling are more intense than with conventional convective heat transfer. Therefore, the mass and dimensions of the TCS based on the TPC will be less than based on single-phase circuits. The thermally regulated pressure accumulator (HCA) is the most important element of the TPC. The article proposes a simplified two-temperature mathematical model for describing nonequilibrium heat-mass transfer processes in HCA under zero gravity. The mathematical model of the HCA is formed using the method of idealized elements. The authors detail the energy conservation equations for control volumes and thermal units, mass conservation equations, equations for heat fluxes and mass sweats. It allows you to quickly carry out the calculation and analyze an acceptable result for preliminary estimates. Previously, the authors published the work, which describes a detailed multi-temperature model that allows us to estimate the nonequilibrium in the liquid phase. A detailed model allows you to calculate almost any process in the HCA with fairly high accuracy, but the program is quite voluminous and the calculation takes a lot of time. Therefore, on the recommendation of the developers of the AMESim software package, the authors formed a simplified two-temperature nonequilibrium HCA model. The model is implemented in Fortran software and tested to establish a quasistationary regime and tested for thermal balance. Based on the data of a space experiment on heating HCA with ammonia, the estimated value of the convective component of heat transfer under zero gravity is estimated. This concept and model can be refined based on the actual design of the accumulator. For example, equations can be written for a cylindrical HCA, placing the heater on the surface of the housing or in the center, etc.

To determine the influence of the igniter body various geometric parameters, affecting the formation and combustion of the fuel-air mixture, a parametric model was developed. This model together with the developed project in the ANSYS Workbench software package made it possible to automate the modeling process. The influence of the geometric parameters of the igniter body and external factors on the average flame temperature has been studied via a numerical model of the stationary combustion process of the air-fuel mixture formed inside the igniter of the combustion chamber of a gas turbine engine by evaporation and spraying particles of aviation kerosene in the air stream. The adequacy of the numerical simulation results was confirmed by the implementation of a series of full-scale experiments using the Fisher criterion.The uniformity of temperature and adequacy of the average temperature estimation algorithm was established using the correlation analysis of the results of measured temperature at various points of the flame. To determine the degree and nature of their influence, sequentially screening (fractional), as well as full-factor experiments with varying factors at two and three levels were implemented. Based on the results of the analysis of variance, the most statistically significant factors were selected. A regression dependence was established that relates the diameter of the air inlet orifice and the air pressure drop to the flame temperature. A qualitative and quantitative assessment of the influence of the considered factors on the process of formation of a hot air mixture and its combustion has been performed. The optimal values of the geometric parameters of the igniter body and its operating conditions are determined under which the maximum flame temperature at the stationary combustion stage is ensured. Relationships between design features, igniter operation mode, and the temperature of the flame are established. This allows expanding the range of stable ignition of gas turbine engine combustion chambers in accordance with the design of the igniter, the starting fuel supply mode, and the air pressure drop.

The problem of utilization of low-potential thermal emissions of the Power plants of industry, transport, energy, with the help of thermoacoustic energy-saving systems may be solved. Such systems are separate functional modules connected to the main power plan with transitional systems that provide energy exchange between external energy sources and thermoacoustic engines (TAE). These intermediate systems are circulating circuits, include external heat exchangers, for direct contact with energy sources, and internal, which are components of the thermoacoustic engine. Design features of thermoacoustic energy-saving systems define the use of recuperative heat exchangers of tubular-rib design with cross-movement of coolants.Known, that at the outlet of such heat exchangers, the coolants have a significantly inhomogeneous temperature distribution in the cross-sections. In this case, this will lead to the formation of inhomogeneous temperature distribution in the structural elements of the thermoacoustic transformation core of TAE, which is an unwanted phenomenon. Existing theoretical models of thermoacoustic and methods of calculation of TAE have built within the linear theory, which assumes the presence of a purely homogeneous distribution of thermophysical parameters in the cross-sections of any elements of TAE - resonators, heat exchangers, matrices, etc.The mathematical model of temperature distribution in the TAE matrix depending on the temperature field on the surface of heat exchangers of the TAE was developed. The peculiarity of the proposed model is taking into account the influence of the initial hydrodynamic stabilization of the flow on the intensity of heat transfer. Cases of using different types of intermediate coolants, such as water or thermal fluids, have been investigated. Numerical simulations have shown that the inhomogeneity of the temperature distribution in the cross-section of the TAE matrix leads to a decrease in the possible capacity of TAE by 1.1 to 1.4 times.  The use of heat exchangers based on phase transitions in thermoacoustic energy-saving systems can reduce the level of temperature field inhomogeneity in the matrix, which will increase the efficiency of the thermoacoustic system.

The task of synthesizing optimal signal processing in synthetic aperture radars equipped with a selection mode of power lines was solved by the maximum likelihood method. The distinguishing features of power lines from the earth's surface selected polarization and Doppler differences. The useful signal at the output of the coherent receiver specified in an analytical form with a complex envelope and high-frequency harmonic oscillations. The background radiation of the underlying surface is presented in a stochastic form and is completely determined by the matrix of correlation functions. The internal noise of a multichannel receiver is described by a delta-correlated random Gaussian process with the same power spectral density in different observation channels. Since the background radiation of the earth's surface is correlated in time and at different polarizations functional likelihood recorded with the inverse matrix inverse correlation functions. The obtained optimal algorithm consists of suppression of passive interference in decor-leveling filters, optimal coherent accumulation of trajectory signals for synthesizing the on-board antenna aperture, and their optimal filtering in filters matched with the reference signal.  Simultaneous use of Doppler and polarization differences between wanted signals and passive interference allows you to effectively allocate power lines against the background of reflections from the ground in multichannel synthetic aperture radars. The proposed sequence of operations on the received oscillations can be a functional addition to the operating modes of aerospace-based cognitive radars, adapting by the covariance scattering matrix of the underlying surface known in advance or measured during remote sensing. The block diagram of a multichannel onboard polarization radar with a synthesized antenna aperture is synthesized based on the obtained results. The development of such a radar is relevant for a collision warning system for helicopter pilots, especially in bad weather conditions at any time of the year, day and night.

It is proposed to evaluate the efficiency of the application of the technology for the production and safe accumulation of hydrogen from the Black Sea hydrogen sulfide by effective capacity, which includes: thermal power of hydrogen, power of the regeneration circuit; the power needed to carry out hydrogen production processes. It is proposed to use the 20RPD-4.4/1.75 rotary piston engine as a hydrogen sulfide expansion machine that will satisfy all the requirements. Rational operating modes and limiting values of the efficiency of using the technology for obtaining and safe accumulation of hydrogen from the Black Sea hydrogen sulfide for daily hydrogen production of 200 kg/day were determined depending on the degree of hydrogen sulfide conversion during destruction, the gas content of hydrogen sulfide in seawater and the depth of immersion of the lifting pipeline using the regeneration circuit. The minimum permissible degrees of conversion at which the efficiency of using the technology for obtaining and safe accumulation of hydrogen from the Black Sea hydrogen sulfide for a gas content of hydrogen sulfide of 2.5 m3/m3 at a depth of immersion of the lifting pipeline of 250...1000 m is 0.427 ... 0.413, for 5 m3/m3 – 0.375...0.363, for 7.5 m3/m3 – 0.363...0.350, for 10 m3/m3 – 0.356...0.343. The use of the regeneration circuit allowed us to reduce the minimum permissible degrees of conversion for the gas content of hydrogen sulfide of 2.5...10 m3/m3 at a depth of immersion of the lifting pipeline of 250...1000 m by 0.136 ... 0.069.

The thrust of a turboprop engine depends on many factors, one of which is hydraulic loss when flowing around the propeller blades. When using coaxial propellers, this factor plays an even greater role, since in this case the losses associated with the swirl sheet behind the first propeller were added. The aim of the work is to assess the influence of the axial clearance between the rows of the coaxial propeller on the thrust. The object of the study is a coaxial propeller. The axial clearance between the rows of the propeller ranged from 650 mm to 950 mm. Geometrically, the calculation model was a cylinder with a radius of 75 m and a height of 150 m. A coaxial propeller was located in the center of the cylinder. The investigated computational model is divided into four subregions: the external environment, the input guide vane, the first row of the propeller, the second row of the propeller. Separation of the calculation model into those listed below for the region allows us to evaluate the effect of the engine air intake on the propeller parameters and to ensure the correct modeling of flow around two rows of the propeller. In the first step of the study, a comparison was made of the results of numerical simulation with the results of an approved mathematical model for a version of a propeller with an axial clearance of 650 mm. The calculations were carried out with three models of turbulent viscosity: k-ω, SST, SST Gamma Theta Transitional. Based on the comparison, the SST turbulent viscosity model was selected for further research. The second research step included flow modeling for a modified coaxial propeller with an axial clearance between the propeller rows of 950 mm. According to the results of the study, it was found that the magnitude of the axial clearance between the rows of coaxial propeller affects the thrust. It is shown that when the clearance between the rows of the propeller increases from 650 mm to 950 mm, the thrust of the propeller increases by 17 %. This can be explained by a decrease in the level of unevenness and hydraulic losses behind the second row of the propeller. In the future, the obtained results of a numerical experiment require agreement with a field experiment.

To reduce the vibration stresses arising in the working blades of turbines during resonant excitations caused by the frequency of passage of the blades of the nozzle apparatus, it is necessary to control the level of aerodynamic exciting forces. One of the ways to reduce dynamic stresses in rotor blades under operating conditions close to resonant, in addition to structural damping, maybe to reduce external exciting forces. To weaken the intensity of the exciting forces, it is possible to use a nozzle apparatus with multi-step gratings, as well as with non-radially mounted blades of the nozzle apparatus.This article presents the results of numerical calculations of exciting aerodynamic forces, as well as the results of experimental measurements of stresses arising in pairwise bandaged working blades with a frequency zCA ⋅ fn, where fn – is the rotor speed, zCA – is the number of nozzle blades. The object of research was the high-pressure turbine stage of a gas turbine engine. Two variants of a turbine stage were investigated: with the initial geometry of the nozzle apparatus having the same geometric neck area in each interscapular channel and with the geometry of the nozzle apparatus obtained by alternating two types of sectors with a reduced and initial throat area.The presented results are obtained on the basis of numerical simulation of a viscous unsteady gas flow in a transonic turbine stage using the SUnFlow home code, which implements a numerical solution of the Reynolds-averaged Navier-Stokes equations. Discontinuity of a torrent running on rotor blades is aggravated with heat drops between an ardent flow core and cold jets from film cooling of a blade and escapes on clock surfaces. Therefore, at simulation have been allowed all blowngs cooling air and drain on junctions of shelves the impeller.As a result of the replacement of the nozzle apparatus with a constant passage area by a nozzle apparatus with a variable area, a decrease in aerodynamic driving force by 12.5 % was obtained. The experimentally measured stresses arising in a pairwise bandaged blade under the action of this force decreased on average by 26 %.
