FLOW AND HEAT TRANSFER ANALYSIS OF MICROCHANNEL HEAT SINK WITH SOLID INSERTS FOR ELECTRONIC COOLING APPLICATIONS
Authors: Kumar D. Sathish , Jayavel Somasundaram
Published: June 2023

The emerging field of electronic industry requires compact electronic components without sacrificing the reliability
and performance of the equipment. The microchannel heat sink is the efficient liquid cooling technique to dissipate
large heat flux in a miniature electronic component. In this study, the improvement in hydrothermal performance
of conventional plane microchannel heat sink is analyzed by introducing different solid inserts in the channel
flow path. A three-dimensional thin-walled rectangular microchannel with fixed aspect ratio and hydraulic
diameter is considered for numerical analysis. The study aims to enhance the heat transfer by breaking the thermal
boundary layer and decreasing the convective thermal resistance with small increase in pumping power. The
coolant and solid insert used in the study are water and aluminum, respectively. Finite volume method-based
solver ANSYS Fluent is used for simulating all cases. The effects of different inserts on fluid flow and heat transfer
characteristics are analyzed for the Re number range of 500 ≤ Re ≤ 1000. The entropy generation minimization
principle and performance index are the methods used for analysis. Based on the combined effect of flow and thermal
characteristics, the insert with converging rectangular geometry gives the overall best performance. The optimum
insert is further modified by varying the convergent angle in order to achieve a maximum possible heat transfer
enhancement.
AN ALTERNATIVE PROCESS-BASED APPROACH TO PREDICTING THE RESPONSE OF WATER-SATURATED POROUS MEDIA TO HARMONIC HYDRODYNAMIC LOADS
Authors: van Damme Myron , der Horst D. den Ouden-van
Published: June 2023

Methods have been developed to predict how hydrodynamic loads acting on nearly saturated porous media are transmitted to the subsoil. In line with the effective stress principle of Terzaghi, these methods apply the boundary conditions that the effective stresses at the surface of a porous medium are zero, and that the pore water pressures carry the full load. Here, a new approach is presented which is based on defining a stress and a stress gradient as boundary conditions.
The stress gradient follows from the momentum balance equation, thereby assuring that the solution abides
by d'Alembert's principle of minimization of virtual work. The corresponding solution is in full accordance with the
volume and momentum balance equations of the linear elastic soil matrix and the volume and momentum balance
equations of the pore water across the computational domain. The new method is thereby able to correctly reproduce
measurements of pore pressure changes due to hydrodynamic loads under the assumption of a porous medium consisting
of incompressible particles and pore water which could either be compressible or incompressible. The advantage of
the proposed method is that it requires one less boundary condition at the surface of the porous medium. The method
is therefore able to predict the magnitude of the effective stresses on a soil surface. Due to the ability to retain the assumption of incompressible water, the method has also become independent on a calibration parameter. The results of the method induce questions with respect to the validity of Terzaghi's principle of effective stress at the boundary when porous media are subjected to hydrodynamic loads.

Authors: JO Jeje , KT Oladepo , SO Oyegoke
Published: June 2023

This study undertook the generation of electricity from abattoir waste with the aim of eliminating the polluting effects of this waste. To achieve the aim of the study, three abattoirs were randomly selected within Ile-Ife in Osun State, southwest Nigeria. Using interactive and investigative methods, the average number of cows and goats that were slaughtered daily, weekly and monthly was established; and the amount of waste generated was subsequently estimated. Water samples were collected from water sources for the abattoirs. Wastewater samples were also collected at different carefully selected stages of the abattoir processes. The wastewater samples were exposed to air for 6 hours to 48 hours. The water and wastewater samples were then subjected to physico-chemical analysis, using standard procedures. Using standard method and appropriate materials, salt bridge was prepared and Microbial Fuel Cells (MFC) were assembled. Subsequently, electrical set up was done, abattoir wastewater introduced into the chamber and electricity generated and evaluated. Voltage, voltage drop, power and current readings were observed and recorded for a period of six (6) days (between 131-144 hours). Surveys revealed that an average of two (2) cows was slaughtered daily in each abattoir. Results showed that the quantity of waste generated from each abattoir per day stands at 100-120 kg per day. For fresh water samples, the pH fell within WHO standard (6.98 to 7.05); while the average pH value for the wastewaters showed that it is basic. Also, for fresh water samples, TS, TSS and BOD values met WHO standard (340 to 440 mg/l), 200 to 220 mg/l and 240 to 600 mg/l) respectively, while the values were excessively high for wastewaters. Generally, the voltage generated from waste with longest exposure to air had the least values. The study concluded that electricity generation is possible from abattoir waste using microbial fuel cells.

Published: June 2023

İklim değişikliği ve nüfus artışı baskısıyla yükselen gıda güvenliği tehlikesi ekilebilir arazilere olan ihtiyacı artırmakta; aynı zamanda yenilenebilir enerji yatırımlarının hızlanması arazi kullanımı üzerinden enerji üretimi ile tarımsal üretim arasında çatışma olasılığı yaratmaktadır. Son yıllarda güneş enerjisi alanında yenilikçi bir çözüm olarak geliştirilen tarım-fotovoltaik (agri-photovoltaic) sistemler ise aynı arazi üzerinde ikili kullanımı mümkün kılmakta, tarımsal arazi üzerinde yükseltilmiş paneller sayesinde enerji üretimi ve tarımsal faaliyetler eş zamanlı olarak sürdürülebilmektedir. Türkiye’de hem iklim değişikliğinin tarımsal üretim üzerindeki etkileri ile ortaya çıkması muhtemel üretim ve gelir risklerini hafifletme potansiyeli açısından, hem de tarımsal üretimin sulama gibi ana ihtiyaçların karşılanmasında yüksek düzeyde dışa bağımlı enerji ihtiyacını ikame etme potansiyeli açısından TarımFV’nin etkilerinin değerlendirilmesi önemlidir. Bu çalışma Türkiye’de bu alanda yapılmış ilk çalışmalardan biri olarak literatürün sistematik bir analizi ile TarımFV sistemlerinin ortaya çıkardığı olası fırsat ve zorlukları tartışmakta ve literatür taraması bulguları ışığında Türkiye’deki tarım sektörünün durumu özelinde (özellikle bir tarım girdisi olan enerji ihtiyacının artışı ve iklim değişikliğinin tarım üzerinde yarattığı zorlayıcı etkiler göz önüne alınarak) TarımFV potansiyelini değerlendirmektedir. Ayrıca tarım ve enerji alanındaki aktörlerin henüz pratikte kullanmadıkları TarımFV’ye ilişkin görüşlerine dair bir ön inceleme sunmak amacıyla Türkiye’de TarımFV kapsamında yapılan ilk saha çalışmasının sonuçlarına da yer verilmektedir.
İKİ BAŞKAN TEK KURAL: TCMB’NİN TAYLOR TİPİ REAKSİYON FONKSİYONU TAHMİNİ

Published: June 2023

2008 küresel finansal krizi para politikalarını köklü biçimde değiştirmiş olmasına rağmen Taylor Kuralı’nın uygulamada hala geniş yer bulduğu görülmektedir. Bu çalışmanın amacı iki alt dönem için Türkiye Cumhuriyet Merkez Bankası’nın reaksiyon fonksiyonunu Genişletilmiş Taylor Kuralı modeliyle incelemektir. Bu sayede kriz sonrası dönemde Türkiye’de para politikasının hangi makro iktisadi değişkenlere ne kadar duyarlı biçimde değiştiği belirlenmektedir. Bu amaçla, 2011:04-2019:07 dönemi para politikası genişletilmiş Taylor Kuralı ile modellenerek, doğrusal Vektör Otoregresif (VAR) yöntemiyle tahmin edilmiştir. Analizde TCMB başkanlarına göre iki alt döneme ayrılmıştır. 2011:04-2016:03 arası dönem Erdem Başçı, 2016:04-2019:07 arası dönem de Murat Çetinkaya dönemini temsil etmektedir. Ekonometrik analizde kullanılan veriler TCMB ağırlıklı ortalama fonlama maliyeti, enflasyon oranı, sanayi üretim endeksi ve USD/TL döviz kurudur. Etki tepki analizine göre temel bulgular, her iki dönemde TCMB’nin döviz kurundaki meydana gelen bir şoka karşı artarak tepki vermekte, sanayi üretim endeksinde meydana gelen bir şoka tepki vermemektedir. Şokların şiddeti ise iki dönemde farklı olmaktadır. Çetinkaya döneminde faiz oranı Başçı dönemine göre döviz kurundaki dalgalanmalara daha şiddetli tepki vermektedir. Varyans ayrıştırması da bu sonucu destekler niteliktedir. Çetinkaya döneminde döviz kurunun, faiz oranının varyansı içerisindeki payı daha yüksektir. Sonuç olarak iki alt dönemde de reaksiyon fonksiyonu farklı değişkenlere farklı şiddette tepki vermektedir. Çalışma alt dönemdeki etki tepki analizlerine bakarak politika önerileri sağlayacaktır.

Первая произошла после открытия энергии пара, вторая — с внедрением конвейера, третья случилась благодаря созданию компьютера. Фундаментом четвертой стало возникновение цифровых технологий.

Цифровая трансформация привела к появлению качественно новых общественных благ, взаимодействие с которыми рождает новые правоотношения. Новые объекты данных отношений, в свою очередь, также нуждаются в правовом регулировании. Так, информационная трансформация повлияла на быстрый рост рынка цифровой интеллектуальной собственности, значительно увеличивая финансовые активы владельцев этих объектов. Однако такое стремительное появление различных объектов, созданных интеллектуальным трудом в цифровой среде, также способствовало различным злоупотреблениям и правонарушениям в связи с отсутствием четкого правового регулирования. Одним из таких быстро развивающихся объектов сегодня являются невзаимозаменяемые токены NFT. Первыми в использовании NFT выступили предприниматели творческой индустрии, которые стремились повысить свои доходы и найти новые способы взаимодействия с покупателями. Несмотря на быстрый рост популярности, были высказаны опасения по поводу законного владения активами NFT и распространению спекуляций и мошенничества, связанных с торговлей NFT.
THE MMP9 −1562 C/T POLYMORPHISM IS ASSOCIATED WITH INCREASED RISK OF DIABETIC RETINOPATHY IN TURKISH TYPE 2 DIABETES MELLITUS PATIENTS
Authors: MUTLU İÇDUYGU Fadime , AKGÜN Egemen , ALP Ebru , DOĞUİZİ Sibel , ÖZER Murat Atabey
Published: June 2023

Objective

Type 2 diabetes mellitus (T2DM) and diabetic

retinopathy (DR) development is affected by genetic

factors. Matrix metalloproteinases (MMPs) are involved

in many cellular processes, such as remodeling of

extracellular matrix proteins and angiogenesis. In

this study, we investigated the relationship between

MMP9 −1562 C/T (rs3918242) polymorphism and the

development of T2DM and DR in Turkish population.

Material and Method

A total of 510 participants, involving 168 T2DM

cases with DR, 168 T2DM cases without DR,

and 174 controls, were included in the study. The

polymerase chain reaction-restriction fragment length

polymorphism (PCR-RFLP) method was carried out

to identify genotypes.

Results

The CT, CT+TT genotypes and the T allele of the

MMP9 −1562 C/T polymorphism were associated with

increased risk of DR (p=0.001). On the other hand,

no relationship was found between the development

of T2DM and this polymorphism. In addition,

CT (p=0.010) and CT+TT (p=0.015) genotype

frequencies were found to be higher in proliferative

diabetic retinopathy (PDR) cases compared to nonproliferative

diabetic retinopathy (NPDR) cases, but

after regression analysis, only insulin use (p=0.003)

was found to be associated with the development of

PDR.

Conclusion

Our data show that the MMP9 −1562 C/T polymorphism

is associated with the development of DR in Turkish

T2DM patients, but no significant relationship was

found between this polymorphism and the severity of

DR and the development of T2DM.

Authors: Lara Flores Erika , Qi Andy , Reilly Luke , Santiana Marianita , Cookson Mark
Published: June 2023

Induced pluripotent stem cell (iPSC)-derived neurons are an important tool for studying diverse types of neurodegenerative disorders, including Alzheimer’s Disease, Parkinson’s disease, and related dementias. Understanding the molecular and cellular mechanisms associated with these diseases is an important step in developing new therapeutic targets. Here we describe a robust differentiation protocol in which we expressed the human neurogenin 2 (NGN2) transcription factor under a tetracycline-inducible promoter as previously described (Fernandopulle et al. 2018), with several modifications and using a PiggyBac system for delivery. This differentiation protocol yields high percentages of cortical neuron markers.
Desynchronization and Oscillatority in Excitable FitzHugh-Nagumo Networks
Authors: Plotnikov S. A.
Published: June 2023

Study of dynamics of complex networked systems is one of the relevant problems. Networked systems can be in various states, ranging from complete synchronization, when all systems in the network are coherent, to complete desynchronization, i.e. complete incoherence in the functioning of systems. Synchronization phenomenon has already been well studied, namely, the mathematical definitions of synchronization are introduced, algorithms of studying synchronization are proposed, and synchronization conditions of various types of networked systems are established. Whereas a few works are devoted to the study of desynchronization nowadays. This paper introduces output desynchronization notion for networks of nonlinear systems. The definitions about Yakubovich oscillatority are considered and the link between oscillatority and desynchronization in networks of excitable nonlinear systems is established. Excitable systems are stable; therefore, they do not generate oscillations. Adding couplings between such systems can lead to occurrence of oscillations. The conditions about oscillatority in diffusively coupled networks of FitzHugh-Nagumo systems, which are the simplest neuron models, are derived. Firstly, the case of the simplest network of two coupled systems is considered, and afterwards, obtained result is generalized for the case of several systems. Laplace matrix spectrum plays crucial role in dynamics of such networks. The condition that connects the parameters of the uncoupled system in the network and the eigenvalues of the Laplace matrix, is obtained which determines whether the network is oscillatory or not. The number of systems that generate oscillations in such a network depends on the number of eigenvalues of the Laplace matrix that satisfy the obtained conditions. Obtained analytical results are confirmed by simulation. The results of simulation of complete desynchronization in the network, when all systems begin to oscillate, as well as a chimera-like state, in which only a part of the systems oscillates, while the other part are rest, are presented.
Production and investigation of the mechanical properties of polypropylene-biosilica composites
Authors: SUDİ Solomon , MSHELİA Richard Balthi
Published: June 2023

Polypropylene (PP) as thermoplastic has found use in the production of a variety of items due to its cheapness which is related to its ease of production. However, its usage is limited due to limitations inherent in its mechanical properties. On the other hand, the production of biosilica (BS) from rice husk ash is a relatively easy process and a cheap source for silica. This, therefore, makes the possibility of production of polypropylene-biosilica composite to further reduce the cost of PP and increase its wide range of applications a field of research. This research developed PP-BS composites with varying compositions of BS and tested their mechanical properties. The mechanical properties like tensile strength, flexural strength, toughness and hardness were experimentally determined using ASTM standard test methods. It was found that the addition of BS to PP does not significantly change its ultimate tensile strength. It was also found that the addition of biosilica to PP causes an average rise in other mechanical properties of the PP matrix-like Young’s Modulus and Flexural Modulus. Whereas, for other mechanical properties such as toughness and hardness, the addition of biosilica to the PP matrix caused an average decrease in these properties.

Meyve kalitesini belirlemek amacıyla her çeşit/anaç kombinasyonundan tesadüfi olarak 50 meyve alınmış ve 5 tekerrürlü (10 meyve/tekerrür) olarak fiziksel ölçüm ve kimyasal analizler yapılmıştır. Alıç anacı, yenidünya çöğür anacına göre meyve deriminde (17 Mayıs) iki gün erkencilik sağlamıştır. Meyve ağırlığı ve meyve boyutları, alıç anacında sırasıyla, 16.89 g, 32.13 mm ve 34.62 mm; yenidünya çöğür anacında 18.32 g, 31.72 mm ve 33.67 mm olarak belirlenmiştir. Tohum sayısı ve tohum ağırlığı, alıç anacında (sırasıyla 3.40 adet ve 4.40 g) yenidünya çöğür anacından (sırasıyla 4.02 adet ve 5.25 g) daha düşük bulunmuştur. Et/tohum oranı bakımından alıç anacından (2.84) yenidünya çöğür anacına (2.50) göre daha yüksek değer elde edilmiştir. Suda çözünebilir kuru madde değeri, alıç anacı üzerinde yetiştirilen meyvelerde %9.40 yenidünya çöğür anacı üzerinde yetiştirilen meyvelerde %11.30 olarak belirlenmiştir. Titre edilebilir asit değeri, alıç anacında %0.34, yenidünya anacında %0.44 olarak hesaplanmıştır. Anaçların, meyve kabuk ve et renklerine etkisi genellikle benzer olmuştur. Sadece meyve kabuk rengi L ve a*(kırmızı-yeşil renk) yenidünya anacı üzerinde yetiştirilen meyvelerde alıç anacına göre daha yüksek bulunmuştur. Birim gövde kesit alanına düşen verim ve birim alana verim bakımından alıç anacı (sırasıyla, 1.48 g mm2 -1 ve 1141 kg da-1), yenidünya çöğür anacından (sırasıyla, 0.79 g mm2 -1 ve 1051 kg da-1) daha yüksek değerler vermiştir. Ancak, daha kesin yargıya varılabilmesi için çalışmanın devam ettirilmesi gerekmektedir.
Seasonal Gene Profiling in Tuz Lake with Regard to Biogeochemical Cycling
Authors: Sahin Dogan Suzan , Kocabaş Aytaç
Published: June 2023

Tuz Lake, a thalassohaline lake with a salt rate of 32%, is a unique habitat for a halophilic microbiome. Culture-dependent and independent methods have been applied to identify prokaryotic microbial diversity in Tuz Lake. However, the key processes and genes involved in biogeochemical cycles in Tuz Lake have not been investigated seasonally. The aim of the study is to investigate seasonal gene profiling in Tuz Lake associated with biogeochemical cycling and thereby reveal more about the ecosystem dynamics of this extreme environment. Therefore, the PICRUSt2 tool was applied to analyze the metabolic function of archaeal and bacterial diversity in Tuz Lake. As a result of metabolic functions based on 16S rDNA amplicon sequencing data, it was observed that methane production by H2 and CO2 by anaerobic archaea in Tuz Lake was the predominant methanogenesis pathway. It was determined that sulfur oxidation was the dominant sulfur metabolism, while the reductive citric acid cycle was the dominant carbon fixation pathway.
A Mental Health Self-Screening Tool for Graduate Students
Authors: Tucker Sharon , Ohr Sidney , Roberts Haley
Published: June 2023

Background: Excessive perceived stress and mental health crises are escalating among college students. About 50% meet mental health disorder criteria, and half of them receive inadequate treatment.
Aim: This study aimed to evaluate the feasibility and outcomes of a 15-20 minute online, anonymous, mental health self-screening survey and resource tool for graduate students across a large midwestern university campus.
Methods: A descriptive, correlational design addressed the study's aims. Recruitment occurred through multiple campus communication mechanisms and included a brief study description, quick reference (QR) code, and weblink to access the tool and survey. Data collected with the tool included demographic items and scores from standardized screening instruments measuring burnout, perceived stress, depression, anxiety, post-traumatic stress disorder (PTSD), alcohol misuse, and health behavior practices. Descriptive and correlational statistics were computed.
Results: Among 778 graduate students who accessed and completed the survey, nearly 60% met the burnout threshold, 58% scored 8 (of 16) on the stress scale, 32% met the depression threshold, 47% met the anxiety threshold, 54% reported one or more symptoms of PTSD, and 38% reported poor health behaviors. Significant positive correlations (r = 0.184 to 0.615) were found between burnout, perceived stress, depression, and anxiety. Health behavior scores were significantly negatively correlated (r = -0.151 to -0.283) with burnout, perceived stress, depression, and anxiety. Scores differed by gender, race, and graduate student status (part-time vs. full-time). Female identifying students, age, and hours worked per week were associated with various outcome scores. Students commented that the tool needed more specific resources tailored to their scores.
Conclusions: The data support the need for tailored coping resources based on student self-reported data. Video-based micromodules guiding individuals through coping skills (breathing, mindfulness, identifying negative thoughts, gratitude exercises) have since been developed and will be studied as a tailored resource for students.
Student Responses to Switching to Online Nutritional Interventions During Pandemic in a Latin-American University
Authors: Enriquez Jean Pierre , Hernandez Santana Adriana
Published: June 2023

Background: Creating positive visions and attitudes in university students through educational interventions is challenging. Gamification-based programs can create an inclusive space where the student and trainer can strengthen learning in a dynamic process, which helps students find a mechanism that facilitates learning, and provides a useful way to comprehend academic content.
Aim: The aim of this study was to document the final experience of first-year university students on the adaptability to transition from in-person to online interventions from a program of nutritional and sustainability education through gamification concept theory.
Methods: This study reviews the results of the transition to online modality, due to COVID-19, of a nutritional education intervention with first-year university students (n = 85) from 16 countries in the Americas.
Results: The findings indicate that most of the students perceived improvement in their eating habits during the confinement period due to the information provided in the different sessions of the educational intervention.
Conclusions: Most students would have preferred that the intervention had been in person; however, they did not feel a sudden change due to the transition from face-to-face to online, demonstrating their resilience to the pandemic.

Real-time Fast Selection System with Object Recognition and TSP algorithms
Authors: Demir Mert
Published: June 2023

The stage before the conversion of agricultural products into post-harvest consumer products is the process of separating the raw products into appropriate classes. Today, this difficult manual separating process is a process in which a large number of workers work at an intense pace on the product line and the workforce is intensively spent. Disruptions in separating as a result of carelessness cause product loss, loss of time and cost increases. In this study, as an alternative to manual separating processes, a real-time separating system, which detects the products in the factory band with object recognition methods and enables fast positioning of the separating tool on the products, works simultaneously with object recognition and traveling salesman problem algorithms has been created. In this way, a low-budget separating system is recommended for large selecting processes with a time- and cost-effective selecting model. In the study, the creation of a real-time fast separating system with the support of the traveling salesman algorithm, performance evaluation and research and findings on the fast separating model are presented.
Recursive-Parallel Algorithm for Solving the Maximum Common Subgraph Problem
Authors: Vasilchikov Vladimir V.
Published: June 2023

The paper proposes an algorithm for solving the problem of finding the maximum common subgraph. Both the sequential and the parallel version of the algorithm, their software implementation are described, and an experimental study of their effectiveness is carried out.

This problem is one of the most famous NP-complete problems. Its solution may be required when solving many practical problems related to the study of complex structures. We solve it in a statement when we need to find all possible isomorphisms of the found common subgraph. Due to the extremely high complexity of the problem, it is natural to want to speed up its solution by parallelizing the algorithm.
To organize parallel computing, the author used the RPM_ParLib library. It allows to develop effective applications for parallel computing on a local network under the control of the runtime environment .NET Framework.The library supports a recursive-parallel programming style and provides effective work distribution and dynamic load balancing of computational modules during program execution. It can be used for applications written in any programming language supported by the .NET Framework.
The purpose of the numerical experiment was to study the acceleration achieved due to the recursive-parallel organization of calculations. For the experiment, the author developed a special application in the C# language designed to generate various sets of initial data with specified parameters. The paper describes the features of the generated initial pairs of graphs, as well as the results obtained during the experiment.

Published: June 2023

This study aims to identify Muslim hospitality potential in the Central Java tourism industry. This research uses a hybrid research method or a Multiphase Mixed Method. Multiphase data were collected simultaneously between qualitative and quantitative data. Data were taken from literature studies, field observations, and in-depth interviews with key informants. The analytical methods used in this study included the Mic-Mac and Mactor analytical instruments, descriptive statistics, and Triangulation Methods. Results of the study show that although Central Java has not applied MFH regulations, the halal tourism industry is practiced in tourism. Central Java has all the potential for Muslim Hospitality with a score of 3.8 out of 5 based on the Indonesian Muslim Travel Index (IMTI) category. The potential for various scenic destinations, polite manner of community, stable and safe political conditions, financial institutions’ support, the existence of Islamic boarding schools, and both tangible and intangible Islamic historical heritage are all the strengths of MFH in Central Java. The theoretical implication of this research can be used as a starting point for further research. Whereas the applied implication suggests that the government needs a seed to immediately formulate regulations on Halal Tourism as affirmed by the state.

Современные зарубежные исследования самоотношения у студентов с нарушением пищевого поведения
Authors: Осинская С.А., , Венгер В.В
Published: June 2023

Представлен теоретический обзор современных научных работ зарубежных исследователей по проблеме самоотношения у лиц юношеского возраста с нарушениями пищевого поведения. Описаны особенности негативного самоотношения молодых людей, их влияние на развитие и поддержание нарушений пищевого поведения. Высокая распространенность расстройств пищевого поведения приводит исследователей к необходимости изучения доклинических проявлений, которые создают дополнительный риск развития нарушений в области питания и оказывают неблагоприятное влияние на соматическое и психологическое благополучие. Юношеский возраст является периодом манифеста пищевых расстройств. Переход к студенческой жизни может быть стрессовым для большинства молодых людей, поскольку требует адаптации к новым условиям и социальным ролям, что также повышает риск развития нарушений пищевого поведения. Теоретическую основу работы составили основные положения отечественных и зарубежных концепций самосознания как динамического образования психики, которое пребывает в постоянном движении не только в онтогенезе, но и в повседневном функционировании. Особенности самосознания оказывают значимое влияние на формирование психических нарушений различного генеза и нарушений пищевого поведения, в частности, поскольку поведение человека неразрывно связано с функцией самосознания
