Background

Marijuana use is common in persons with HIV, but there is limited evidence of its relationship with potential health benefits or harms.

Objective

The Marijuana Associated Planning and Long-term Effects (MAPLE) study was designed to evaluate the impact of marijuana use on HIV-related health outcomes, cognitive function, and systemic inflammation.

Methods

The MAPLE study is a longitudinal cohort study of participants living with HIV who were recruited from 3 locations in Florida and were either current marijuana users or never regular marijuana users. At enrollment, participants completed questionnaires that included detailed marijuana use assessments, underwent interviewer-administered neurocognitive assessments, and provided blood and urine samples. Ongoing follow-ups included brief telephone assessments (every 3 months), detailed questionnaires (annually), repeated blood and urine samples (2 years), and linkage to medical records and statewide HIV surveillance data. Supplemental measures related to intracellular RNA, COVID-19, Alzheimer disease, and the gut microbiome were added after study initiation.

Results

The MAPLE study completed enrollment of 333 persons between 2018 and 2021. The majority of participants in the sample were ≥50 years of age (200/333, 60.1%), male (181/333, 54.4%), cisgender men (173/329, 52.6%), non-Hispanic Black (221/333, 66.4%), and self-reported marijuana users (260/333, 78.1%). Participant follow-up was completed in 2022, with annual updates to HIV surveillance data through at least 2027.

Conclusions

The MAPLE study is the largest cohort specifically designed to understand the use of marijuana and its effects on HIV-related outcomes. The study population has significant diversity across age, sex, gender, and race. The data will help clinicians and public health officials to better understand patterns of marijuana use associated with both positive and negative health outcomes, and may inform recommendations for future clinical trials related to medical marijuana and HIV.

Quality of Life in multiple scenarios: The impact of work mode and social contact quantity (Preprint)
Authors: Leng Cheng-Han , Tsai Chi-Shiun , Chan Ta-Chien , Lee Hsuan-Wei
Published: July 2022

UNSTRUCTURED

This study aims to explore issues, such as (i) whether there is a difference in quality of life (QoL) among subgroups of the work mode (working from home (WFH) vs. working in the office (WIO)), social contact quantity, and face contact ratio; (ii) whether employees' QoL is moderated by the social contact quantity and face contact ratio given their work mode; (iii) whether the three-way interaction effect of work mode, social contact quantity, and face contact ratio on employee's QoL is significant; and (iv) whether the WHOQOL-BREF invariantly measures for the subgroups of the work mode, social contact quantity, and face contact ratio. We assessed the QoL of 803 WFH employees and 588 WIO employees during the same time period and divided them into sixteen groups resulting from the levels of work mode, social contact quantity, and face contact ratio, forming a case-control study. A differential item functioning (DIF) analysis was used for analyzing the responses on the WHOQOL-BREF under the 4-dimensional rating scale model fitting. Our results indicated that WFH employees' QoL was superior to that of WIO employees. However, since the work mode was moderated by the social contact quantity and face contact ratio, WFH employees' QoL was worse than that of WIO employees if their amount of social contact was low and if most social contacts were not face-to-face. Moreover, WFH employees' QoL was better than WIF employees' QoL when most contacts were not face-to-face and the number of social contacts was high. Besides, the WHOQOL-BREF measured employees' QoL biasedly as many facets of the WHOQOL-BREF were found to diverge among subgroups of the work mode and social contact quantity. The WFH mode was practical in the COVID-19 pandemic. However, maintaining social connections is equally important so that employees can maintain good performance in jobs. The facets detected as DIF items provided implications for QoL research methodology and insight into factors affecting employees' QoL.

Authors: Panchakshari Aradhya Abhishek Budiguppe , Jain Spoorthy
Published: July 2022

Fast mapping refers to the acquisition of new words in children just by the virtue of mere exposure. With a minimal exposure the words are imbibed. This study was carried with the aim of comparing the fast mapping and slow mapping in typically developing children. A total of 20 children in the age range of 5-6 years were considered for the study and the participants were divided into two groups on random basis. Fast mapping and slow mapping methods were used to train the first and group respectively. In fast mapping, the participants were exposed to the label of the target word for 5 times. In slow mapping method, the semantic features related to the target word was taught to the participants. The number of words learnt by group 1 and group 2 children was computed on immediate naming task and delayed naming. Statistically there was no significant difference between number of words learnt on fast mapping and slow mapping as observed on Mann-Whitney U test. While there was significant difference between the two methods on delayed naming as proven by the same statistic. More number of words learnt through slow mapping suggested that it was effective in evoking learning.

Abstract: One recent technique in the field of cryptography is DNA cryptography. DNA can be utilised to do computations as well as encrypt data for storage and transmission. Making a DNA sequence plays a key function in DNA cryptography. Based on the data carrier and biological technology, the DNA sequence is produced. The goal of this work is to make the DNA sequence more complicated. Giving the data a high level of security is the major goal of this research. Two degrees of security are what this paper's recommended work is. The shift key is used to convert plain text to ASCII text, which is then transformed into a binary integer in the first level. Utilizing the insertion approach, change binary numbers into DNA sequences, which are then represented as cypher text. The receiver will decrypt the cypher text using the Insertion method, and the plaintext will then be displayed. The data compression of the suggested work is measured using the Shannon entropy, and the execution time is measured using the time complexity.
Partial Replacement of Cement in Concrete Mixes Using Ground Granulated Blast Furnace Slag (GGBS) as Secondary Cementitious Material (SCM)
Authors: Kumar Pramod , Parida Ananya P , Mangaraj Abhijit
Published: July 2022

Abstract: Blast furnace slag is a byproduct of Iron & steel industry across the world. It is an industrial waste material obtained by iron and steel making process. Approx 300 kg waste slag is produced for every MT of crude steel production. Annual production of Slag is 35 MT in Odisha, 150 MT in India and approx. 2000 MT in the world. Such a huge volume of industrial waste is generated every year. Considering the physical and chemical properties of slag, it can be utilized in construction industry. Slag is used in cement industry. Slag can be used as partial replacement for sand. The production of cement has always lead to massive exploitation of natural resources. Ordinary Portland Cement being produced yearly around the globe contributes to 5 percent of greenhouse gas and 2.5% of total worldwide waste emissions from industrial sources. One effective way to reduce the environmental impact is to use mineral admixtures, as a partial cement replacement both in concrete and mortar, which will have the potential to reduce costs, conserve energy, and minimize waste emission.

The effect of venting structures on overpressure caused by an indoor explosion
Authors: Gorev V. A. , Korolchenko A. D.
Published: July 2022

Introduction. The article considers an accidental indoor gas explosion on condition of pressure relief through openings in which venting structures were installed.

A solution to this problem can protect residential buildings from consequences of explosions due to the fact that the volume of premises in residential buildings is small compared to industrial buildings, and it determines more stringent pressure relief conditions at the initial moment of the explosion development. The article shows that pressure can reach critical values in a small space during the motion of a venting structure in the opening before the onset of pressure relief.

Goals. The authors aim to identify the pattern of blast load development from the moment of explosion to the attainment of the maximum pressure value with account taken of the properties of venting structures and patterns of their opening. This goal is relevant due to the fact that until now at this stage pressure development has been considered without any account taken of how deeply the venting structure is installed in the wall opening. Much attention was focused on the selection of the opening size.

Methods. The methods of the theory of dimensions, numerical and analytical modeling of explosion processes, patterns of gas escape and rigid body motion were applied to obtain dimensionless groups describing the development of an explosive load until maximum values. These dimensionless groups allow identifying explosive loads for rooms having different volumes, which is also a new result.

Results. In this work, the influence of individual factors on the ultimate result has been identified. These factors are the room volume, the pressure at which the venting structure starts moving, the mass and position of the venting structure in the opening, the opening perimeter and the rate of explosive combustion.

Conclusions. The results, obtained in the course of this work, allow identifying the dynamic load of an explosion at the stage of its growth. This value can be used to set more reliable bearing characteristics of structures for cases of accidental explosions in living accommodations.

Published: July 2022

Introduction. One of the ways to reduce the fire hazard at industrial facilities is the application of intumescent coatings. It is known that intumescent compositions are multicomponent composite materials, whose effectiveness is due to complex chemical transformations of the components of the studied flame retardant exposed to high temperatures. In this regard, the problem of studying the physicochemical processes and thermophysical characteristics of flame retardant thermal expansion materials is in demand and relevant.

The purpose of this article is to analyze the thermophysical properties of water- and acrylic compound-based intumescent flame retardants to improve the safety of oil and gas facilities.

To accomplish this purpose, the following objectives were attained:

studying acrylic dispersion-based intumescent flame retardant materials using methods of thermal analysis;

analyzing aqueous dispersion-based intumescent flame retardant materials using methods of thermal analysis;

making a comparative analysis of the thermo-oxidative degradation of the studied flame retardant materials.

Methods. During the study, thermogravimetric analysis, differential thermogravimetric analysis, differential scanning calorimetry, and quadrupole mass spectrometry were chosen as the main methods.

Results. As a result of the studies performed using methods of synchronous thermal analysis of water- and acrylic compound-based intumescent flame retardants, the similarity of ongoing physicochemical processes was identified, including the presence of four main stages of mass loss and a high exothermic effect. This high thermal effect has proven high flammability of the studied flame retardant materials.

Conclusions. Following the analysis, the authors have concluded that intumescent flame retardants, containing acrylic vinyl acetate emulsion and aqueous dispersion, begin to lose their performance characteristics, necessary for a flame retardant material, when the temperature reaches approximately ~600 °C.
Mathematical simulation of inert heating and pyrolysis of forest fuel under the influence of a forest fire front, if the process of sooting is taken into account
Authors: Baranovskiy N. V. , Vyatkina V. A.
Published: July 2022

Introduction. Large amounts of pollutants, including carbonaceous particles of soot, are released into the atmosphere during a forest fire. High concentrations of these particles in the air can lead to the development of cardiorespiratory diseases or death. It has been noticed that a certain number of soot particles is produced at the stage of forest fuel pyrolysis. In this regard, it is advisable to study the processes of pyrolysis and sooting to develop effective methods of their prediction and prevention.

Goal of the study. The goal of this study is the mathematical simulation of heat transfer in an element of standard forest fuel (a birch leaf), taking into account the thermal decomposition of dry organic matter and sooting.

Materials and methods. Within the framework of the work, scenario modeling of heat and mass transfer processes in an element of forest fuel (a birch leaf), subjected to the influence of a high-temperature environment, was conducted. A one-dimensional heat transfer equation and a kinetic equation, having respective initial and boundary conditions, were solved by means of numerical simulation. The finite difference method was employed to solve the resulting system of differential equations. The calculations were conducted using the RAD Studio software package. Graphical results were processed using the OriginPro software package.

Results. Scenario modeling took into account the type of forest fire, the period of the fire hazard season, forest fuel properties, the degree of the forest fuel dispersion, and the initial moisture content in a forest fuel element. The authors have found that the major influence is made by the extent of dispersion and the type of forest fire. The similarity of qualitative characteristics of sooting has also been established for all types of forest fires.

Conclusion. The proposed mathematical model can be used in conjunction with geoinformation systems to visualize the initial and output information in the process of assessment, monitoring and forecasting of forest fires and their environmental consequences.

Authors: Garashchenko A. N. , Antonov S. P. , Danilov A. I. , Pavlov V. V. , Novikov N. S.
Published: July 2022

Introduction. The authors focus on preventing the explosive spalling of concrete and the fireproofing of reinforced concrete structures. The relevance of this issue is explained by the insufficient number of fire tests of such structures under loading and thermal engineering calculations, needed for an objective analysis of testing results.

Goal and objectives. The authors analyze the results of a series of fire tests, involving concrete columns and slabs with and without polypropylene microfiber, if no fireproofing is applied, as well as the results of the same tests involving the same items fireproofed by plates or plaster.

Methods. The fire resistance of full-scale specimens of concrete was evaluated according to a standardized testing in a fire furnace under loading. It encompasses additional thermocouple measurements used to make a thermal engineering analysis. The analysis entailed both one- and two-dimensional problem formulations, methods and programmes for the numerical computation of non-stationary temperature fields in fireproof structures.

Results. New data, obtained in the course of the fire experiments, show the efficiency of the polypropylene microfiber used to prevent the explosive spalling of concrete. The fire resistance limit is R 120 and R 150 under constant static loading. The fire resistance limit of similar structures, fireproofed by PROSASK Firepanel plates or IGNIS LIGHT plaster, was demonstrated. The specimens show the efficiency of methods and programmes for the one- and two-dimensional numerical analysis of non-stationary temperature fields in fireproof structures. The calculation results are presented for various fireproofing options.

Conclusions. The testing results and their thermal analysis represent important items of information necessary to ensure the fire safety and the pre-set fire resistance of concrete structures under loading. They can also be used to outline the development pattern of this experimental and theoretical research project. The efficiency of thermal engineering calculations as a tool for evaluating fire protection parameters and the fire resistance of concrete structures is demonstrated, also as an option to reduce the number of expensive fire tests.
Estimating the maximum size of explosive iron sulfide particles
Authors: Poletaev N. L.
Published: July 2022

Introduction. There are estimates of the maximum size dcr of explosive particles of the two types of sulfide ores. The estimates are based on a qualitative approach to the dispersion analysis of combustible ore specimens (Soundararajan, Amyotte & Pegg, 1996): 49 μm < dcr, PO < 63 μm for pyrrhotite (PO) and 85 μm < dcr, PY < 145 μm for pyrite (PY). The task was to refine these estimates using the quantitative method of the mentioned analysis, taking into account the lower explosive limit (LEL) of flame propagation in terms of ore suspensions. Experimental data processing method. Continuous functions F of particle size distribution d were constructed for the two polydisperse specimens of pyrrhotite (LELPO,1 = 475 g/m3 and LELPO,2 = 1,375 g/m3) and two polydisperse specimens of pyrite (LELPY,1 = 375 g/m3 and LELPY,2 = 500 g/m3). The obtained functions FPO,1(d), FPO,2(d), FPY,1(d) and FPY,2(d) were converted using Rosin – Rammler distributions, filling the gaps between the discrete data of the grain-size analysis of the specimens. dcr rating. The procedure for estimating dcr (Poletaev, 2014) was employed to find the values of dcr, PO and dcr, PY using the following equations: FPO,1(dcr, PO)/FPO,2(dcr, PO) = LELPO,2/LELPO,1 and FPY,1(dcr, PY)/FPY,2(dcr, PY) = LELPY,2/LELPY,1. The solutions were presented in the visual graphic format.

Discussion of the results. Due to the low values of explosion parameters of pyrrhotite and pyrite in a 20‑liter chamber (maximum explosion pressure Pmax ≤ 350 kPa, index Kst ≤ 2 MPa ∙ m/s), the validity of classifying ores as explosive dusts was discussed. Low explosion values have proven that sulfur is the main fuel in the air suspension. The explosiveness of ores is proven empirically (Selle & Zehr, 1954) by estimating the combustion temperature, which exceeds 1,000 °С.

Conclusions. The values of dcr for sulfide ores have been refined: for pyrrhotite, dcr = 40 μm; for pyrite dcr = 107 μm. In the air suspensions of ores, only sulfur is burnt out, which substantially reduces the explosiveness of ores.
Theory and practice of diagnostics of fire hazardous modes of operation of catalytic converters
Authors: Lozhkin V. N.
Published: July 2022

Introduction. The wide-scale use of catalytic converters and particulate filters in automobile engines has aggravated the problem of their ignition and updated the research and methodological framework for the examination of causes of fire emergency modes (FEMs) of operation of fuel catalytic units (FCUs). The relationship between the FEMs of the FCU operation and failures of the fuel equipment, wear of the cylinder-piston group of engines and deviations in fuel compositions was confirmed. The goal was to develop a diagnostic method for fire hazardous modes of operation of FCUs of vehicles.

Methodology. A model of oxidative catalysis underway in the FCU has been proven rational. The model is used to calculate the thermo-catalytic efficiency and heat generation in the active layer of the γ-Al2O3 platinum catalyst depending on the temperature of exhaust gases (EG), concentrations of CO, CH and soot. It has been found out that catalysis can theoretically develop in four limit domains: internal kinetic domain, internal diffusion domain, external diffusion domain, and external kinetic domain.

Results and discussion. Experimental and computational studies have shown the probability of emergence of breakdown vehicles with a multiple excess of soot emissions and thermal stresses. A 10‑fold increase in CO, CH and soot in EG rises the thermal performance of the catalytic reaction from 17,282 to 491,907 kJ/h, creating a fire hazard in a KamAZ engine. To identify a FEM, the diagnostic method based on the «free acceleration» (FA) mode according to GOST 33997–2016 is proposed. The procedure is supplemented with maximum revolutions and restrictions (0.5 s) of the FA mode time. The latter is necessary for the guaranteed operation of the engine in the «full load mode». The method was applied in the course of the fire engineering studies on a Ford Mondeo car having a TDCi (Common Rail System) diesel engine and a catalytic particulate filter. Laboratory examination and analytical studies have found that the main reason for the operation of FCU in emergency (due to environmental and fire hazards) modes is the corrosion of precision parts of the fuel equipment accumulated during its long-term operation. Progressive corrosion is caused by excessive sulfur and moisture content in fuel and oil.

Conclusions. It’s been proven that the emergency heating of a catalytic converter causes a sharp rise in the car combustion risk. The authors have proposed an original method for the diagnostics of fire-hazardous modes of operation of catalytic converters based on procedures set in GOST 33997–2016 (ТР ТС 018/2011).
Classification of hotels taking into account fire risks
Authors: Prisadkov V. I. , Konstantinova N. I. , Muslakova S. V. , Abashkin A. A.
Published: July 2022

Introduction. The current Russian Regulation on classification of hotels hardly takes into account their fire safety conditions. The system, adopted in the Regulation, provides for an expert scoring assessment of hotel parameters for their assignment to a certain category (star rating). The purpose of the article is to develop methods that allow determining the level of fire safety of hotels in points commensurate with the accepted rating system, for its further use in the course of assignment of appropriate categories to hotels. Theoretical fundamentals of scoring methods of assessment of fire safety of hotels. Three approaches to the calculation of «fire points» of hotels have been developed, based on the breakdown of hotels into classes and identification of the fire safety index of hotels within one class. The first scoring method is the Gretener method used for calculating the integral fire safety index. The first and third quartiles are identified for the hotel statistics. Hotels, whose index does not exceed the first quartile, belong to the subgroup featuring a high level of fire safety; those ranging from the first (inclusively) to the third quartile belong to the medium level. If the values of the fire hazard index of hotels are not smaller than the third quartile, they belong to the subgroup that has a low level of fire safety. The second method is based on the use of a «safety reserve» in terms of evacuation time. The third model of assessing the fire hazard of hotels includes the breakdown of hotels into groups, identification of the value of individual fire risk, ranking hotels by the fire risk that varies from the lowest to the highest.

Results and their discussion. As for the classification of hotels, problems that accompany the consolidation of the physical approach to the fire hazard assessment with the expert method of scoring are solved by choosing the proportion between the points of the system and the «fire points» set by the adjustment coefficient. The fire points, assigned to the subgroups of hotels, are indicative and should be corrected within the framework of the proposed approach.

Conclusions. The experimental application of the developed methods using the cases of real hotel facilities will allow choosing the optimal engineering method of taking into account the fire safety of hotels in the process of their classification.

Authors: Pekhotikov A. V. , Ivashchuk R. A. , Gomozov A. V. , Luchkin S. A.
Published: July 2022

Introduction. Methodological provisions must be developed to evaluate the impact of the fire resistance factor of building structures on human safety during evacuation and rescue with account taken of the composition andfunctional characteristics of other fire safety systems to formulate modern regulatory requirements for the fire resistance of building structures under fire conditions, develop science-based solutions for the fire safety of buildings and structures in case of forced deviations from the fire resistance requirements set in regulatory documents, and justify the construction of buildings and structures, based on modern structural systems, having non-standard fire resistance limits, etc.

The purpose of the article is to develop general methodological provisions and mathematical relationships that allow evaluating the impact of the fire resistance limits of building structures both on safe evacuation and safe rescue from buildings.

Methods. Analytical and mathematical methods are used to evaluate the combined effect of changes in the fire hazard arising along the evacuation routes, in a room with a person waiting to be rescued by fire departments, as well as along the routes taken by fire departments carrying this person out, in combination with the evaluated time span needed for the structure to lose its fire resistance. The value of this time span is used to identify the time available for the safe evacuation and rescue of people.

Results. Theoretical provisions have been developed to take into account the influence of the fire resistance factor of building constructions on the safety of people in a building in case of a fire.

Conclusions. The research findings were contributed to the general methodological provisions and mathematical relationships needed to determine the quantitative relationships between the extent of fire resistance of a building, fire resistance limits of building structures, the time of arrival of fire departments, types of fire alarm and evacuation control systems, and the possibility of safe evacuation and rescue of people from a building.

In Silico Strategy to Control or Treat Nipah Virus Infection in Humans Through Saikosaponin Biomolecules
Authors: Ray Sriparna , Sinha Jayanta
Published: July 2022

The penetrance of deadly Nipah virus causing high mortality in humans is mediated by bats and pigs, and there is lack of licensed drugs against it till date. In India the transmittance is caused among humans through direct contamination of secretion and excretion. In order to combat the fatal Nipah virus, so far one strategy has been concerned in this paper; exploiting extract and resources that are of botanical origin. Usually in India, Favipiravir (T-705) is used as anti-viral medicine against Nipah virus. Chemically it is a pyrazinecarboxamide derivative and is an experimental antiviral drug being developed by Toyama Chemical of Japan with activity against many RNA viruses. As Favipiravir is a synthetic analogue, it may cause some side effects in renal function. This paper aims towards identifying various Saikosaponins as an anti-Nipah viral agent and establish its efficacy in binding of these molecules with a viral phosphoprotein. Thus with such an aim and considering the limitation of synthetic drugs, this paper focuses on the interaction between Nipah virus and natural bioactive compounds Saikosaponins (A, B2, C, D, etc.), which are triterpene glycosides (naturally occurring) being isolated from medicinal plants such as Bupleurum spp, Heteromorpha spp, and Scrophularia scorodonia. Molecular docking of these herbal compounds with Nipah virus phosphoprotein was carried out through Molecular docking server. Lower energy scores represent better binding between Nipah virus phosphoprotein target and Saikosaponins as ligands. It is observed that best binding occurred between Nipah virus and saikosaponins K among the Saikosaponins clearly indicates its importance to be served as a potent drug. Ligplot+ server revealed polar and hydrophobic residues mainly involved in docking.

Bu nedenlerden dolayı günümüz dünyasında kripto paraya olan ilgi gün geçtikçe artmakla beraber kripto paranın kullanımı da yaygınlaşmıştır. Kripto para kullanımın yaygınlaşmasıyla birlikte kripto paraların nasıl muhasebeleştireceği konusu da gündeme gelmiştir. Muhasebe standartları açısından da kripto paralar için herhangi bir düzenleme bulunmamaktadır. Bununla birlikte yapılan çalışmalarda kripto paraların ne tür bir varlık olarak sınıflandırılması gerektiği üzerinde durulmuştur. Yapılan bu çalışmada ilk olarak kripto paralar ile bu paraların ortaya çıkmasına neden olan blokcahin sistemine değinilmiş. Akabinde TMS/TFRS kapsamında kripto paraların ne tür bir varlık olduğu ve muhasebeleştirilmesi örnek olaylarla irdelenmiştir. Çalışma sonucunda spekülatif amaçlı alım-satım yapan işletmeler için kripto paraların “108 Diğer Hazır Değerler” Hesabında, kripto para işletmeciliği yapan işletmeler içinse kazım sonucunda elde edilen kripto paraların “157 Diğer Stoklar” Hesabında izlenmesinin uygun olacağı düşünülmektedir.

Published: July 2022

Sadri Maksudi Arsal, Rusya’nın egemenliği altındaki Kazan’da dünyaya gelmiş Müslüman-Türk azınlığın bir üyesidir. Arsal’ın yaşadığı dönemde Rus hükümeti azınlıkları Ruslaştırma politikası uyguluyordu. Bu durum karşısında Müslüman-Türk azınlık, kendi milli benliklerini koruma mücadelesine girmiştir. Arsal da Müslüman-Türk azınlığın milli mücadelesine katılmıştır. Duma’ya seçilen Arsal, burada soydaşlarının haklarını savunmuştur. İdil-Ural Milli Medeni Muhtariyeti’nin oluşumunda da önemli rol almıştır. Arsal, anayasasını hazırladığı muhtariyetin meclis başkanı ve devlet başkanı olmuştur. Ancak bu muhtariyet yönetiminin ömrü uzun olmamıştır. Politik gelişmelerin ardından Arsal’ın Rusya’da yaşama imkânı kalmamıştır. Arsal’ın soydaşlarına ve Türklüğe olan ilgisi gittiği Paris’te de devam etmiştir. Sorbon Üniversitesi’nde Türklerin tarihi konusunda ders vermiştir. Bu dönemde Arsal yeni kurulan Türkiye Devleti’nde yaşanan gelişmeleri takip etmiştir. Türkiye’de cumhuriyet rejimine geçilmiştir. Arsal, yeni kurulan Türkiye Cumhuriyeti devletine gelmenin hayalini kurmaktadır. Arsal, Türk Ocaklarının davetinden sonra yaşamına Türkiye’de devam etmiştir. Arsal, yeni kurulan devlette önemli görevlerde bulunmuştur. Bu çalışmanın amacı Sadri Maksudi Arsal’ın Türk milliyetçiliğine yapmış olduğu katkıyı ortaya koymaktır. Araştırmanın yöntemi niteliksel içerik analizi ve hermeneutik yaklaşım olarak belirlenmiştir. Bu bağlamda Arsal’ın eserleri, konuşmaları ve Arsal hakkında yapılmış araştırmalar incelenmiştir. Araştırmanın sonucunda Arsal’ın Türk milliyetçiliğine önemli katkılar sunduğu görülmüştür. Arsal, Türk hukuk tarihi, Türklerin tarihi, Türk dili ve milliyetçilik konularında dönemin önde gelen isimlerinden olmuştur.

Authors: AYDIN Salih
Published: July 2022

Küçük ve Orta Ölçekli İşletmeler olarak bilinen KOBİ’ler ülkenin ekonomik kalkınmasına katkı yapan ekonomik birimlerdir. KOBİ’ler, nihai tüketiciye ulaşan ürünleri üretip satmanın yanında büyük işletmelerin ihtiyaç duyduğu ara mal ihtiyacını karşılama noktasında önemli bir misyona sahiptir. KOBİ’ler günlük ihtiyaçlarının finansmanında ihtiyaç duyduğu kaynaklara ulaşma noktasında birtakım problemlerle karşılaşabilir. KOBİ’lerin finansman ihtiyacının karşılanması noktasında ülkemizde birçok kurum ve kuruluş aktif görev almaktadır. Bu kurumlardan birisi de Küçük ve Orta Ölçekli İşletmeleri Geliştirme ve Destekleme İdaresi Başkanlığı olan ve halk arasında KOSGEB olarak bilinen kurumdur. KOSGEB, KOBİ’lerin finansal problemlerine çözüm bulmak adına faaliyette bulunan bir kamu kuruluşudur. Bu çalışmada Artvin ilinde faaliyette bulunan KOBİ’lere sağlanan desteklerde KOSGEB’in rolü incelenmiştir. Bu kapsamda Artvin’deki KOBİ’lere 2021 yılı içerisinde KOSGEB tarafından sağlanan finansal destekler incelenmiştir. Aynı zamanda her bir destek programı kapsamında Artvin’in Türkiye’deki sıralamasına değinilmiştir. Çalışmada, Artvin’de faaliyetlerini sürdüren KOBİ’lerin sınırlı sayıda destekten faydalandığı tespit edilmiştir. Ancak Artvin kadın girişimciliğinin toplam girişimcilik içerisindeki payı anlamında ülke geneline bakıldığında 2. sırada yer almıştır. Artvin’de desteklenen girişimcilerin yarısı kadın girişimcilerden oluşmaktadır. Çalışmanın sonunda Artvin’de faaliyetlerini sürdüren KOBİ’lerin finansal desteklerden daha fazla yararlanabilmeleri için birtakım öneriler sunulmuştur.
Dual-pulse Two-target Resolution for Four-channel Monopulse Radars Configured with Nonrectangular Arrays
Authors: Ｗａｎｇ Ｙｕｆｅｉ , Ma Jiazhi , Tang jianglan , Shi Longfei
Published: July 2022

The two-target resolution algorithm enables four-channel monopulse
radars to estimate the locations of the unresolved two-target within a
3dB beamwidth. However, the algorithm mentioned above has limited
practical use due to the antenna pattern inconsistent of nonrectangular
arrays. For this case, an dual-pulse two-target resolution (DTR) method
for monopulse radars with a nonrectangular array configuration is
proposed in this letter. By solving the eight equations from the
received signals of two continuous pulses, matching functions with nulls
at the real locations of the targets are established, which eliminate
the errors caused by the nonrectangular array configuration. By
searching the nulls, the locations of the two unresolved targets can be
estimated accurately. Simulations demonstrate the superior performance
of the DTR approach.

Published: July 2022

Genomics data analysis requires efficient tools to address the vast
amount of data generated by current next-generation sequencing
technologies. K-mer counting works face difficulties in balancing high
memory overhead with statistical precision. We designed a high-frequency
k-mer statistical computation based on the Space Saving algorithm and a
novel hash table structure, which reduces the memory overhead by
50\% while ensuring high computational efficiency.
Impacto laboral de la COVID-19 en las familias de los estudiantes de la Universidad Tecnológica de Tecamachalco
Authors: Solares Muñoz María Leticia , Flores-Aguilar María de los Angeles , Gámez de la Vega Alicia Sagrario , Hernández-Barrera Tania Ivette
Published: July 2022

Problemática: la problemática se origina en el fenómeno que provocó el aislamiento por la COVID-19. Se observan conflictos colaterales, sobre todo en las familias de los estudiantes. Conservar el alumnado en este contexto inédito tendrá repercusiones en el mantenimiento económico del núcleo familiar y en la accesibilidad al ámbito escolar por medios virtuales. Objetivo: el objetivo es identificar el impacto de la pandemia de la COVID-19 en los empleos de las familias de los alumnos de la Universidad Tecnológica de Tecamachalco, Puebla, México, para identificar las acciones implementadas por los sujetos de estudio. Materiales y métodos: los materiales y métodos utilizados implican un diseño de investigación no experimental, transversal en el espacio / tiempo. Su propósito es describir variables y analizar su incidencia e interrelación en un momento dado. Aunado a ello, esta investigación es correlacional y el enfoque es cuantitativo. Resultados: la muestra de 340 está definida dentro de una población de 2917 estudiantes de la Universidad. Los resultados obtenidos del levantamiento de información se lograron al calcular los índices al agrupar las preguntas dentro de una misma dimensión. En consecuencia, la significancia bilateral en las correlaciones del conjunto de variables estudiadas se encuentra en un rango de 0,387 a 0,0. Discusión: la discusión oscila en la incertidumbre de no saber qué rumbo tomaría la pandemia, el esfuerzo del empleador por mantenerse y la expectativa de una pérdida de empleo. Dadas las observaciones internacionales y la medición del impacto de manera prematura, se obtuvieron resultados no significativos. Conclusiones: finalmente se concluye que el impacto es bajo y casi nulo, por ello queda la posibilidad de realizar futuras investigaciones sobre las causas que definen la situación laboral actual de las familias de los estudiantes de la Universidad. Contribución / originalidad: la contribución y originalidad consisten en que estudiar un fenómeno, como lo es esta pandemia, resulta más complejo aún de lo que pudieran ser números aislados de empleo y desempleo, ya que es un todo integral y, como se verá en la discusión, se tuvo que recurrir a otros datos para comprender el resultado.
