Authors: Luksta Ilze , Mika Taras , Spalvins Kriss
Published: September 2024

This paper presents a study on the use of supercritical carbon dioxide (SC-CO2) extraction to isolate yeast metabolites from beer and wine matrices effectively. A major contributor to the flavour and aroma profiles of alcoholic beverages, yeast contains a rich reservoir of bioactive compounds that can be used in various industries, including food and pharmaceuticals. Conventional extraction methods often fail to obtain comprehensive and high-quality recoveries of these valuable metabolites. In response, this study explores the use of SC-CO2, a green and tuneable solvent, to overcome the limitations of conventional extraction methods. The study investigates the influence of critical process parameters such as pressure, temperature, and extraction time on the yield and composition of extracted yeast metabolites. Advanced analytical methods (gas chromatography for the determination of fatty acids and high-performance liquid chromatography for the determination of the amino acid composition of the yeast residue left after extraction) are used in the analysis to characterize the chemical profile of the extracts. The results show that SC-CO2 extraction offers a promising alternative to extract a diverse range of yeast-derived compounds, including flavour-enhancing esters, phenolic compounds, and bioactive peptides. The optimized extraction conditions show a significant improvement in extraction efficiency compared to traditional methods. Sensory analysis reveals that beverages produced with SCCO2-extracted yeast have distinctive and desirable flavour profiles. This research not only contributes to the development of extraction technologies in the beverage industry but also opens up new opportunities for the use of yeast-derived bioactive compounds in various applications. The environmentally friendly nature of SC-CO2 extraction meets the growing demand for sustainable and clean technologies in food and beverage processing. Overall, the results of this study highlight the potential of SC-CO2 extraction as a valuable tool for improving the extraction of bioactive yeast metabolites, thereby influencing the quality and sensory properties of beer and wine.

Recent challenges in space access include cost optimization and space debris reduction. The European Space Agency has envisioned the evolution of in-orbit transportation involving re-usable service vehicles, moving payloads from high parking orbits to their target orbits. This concept for orbital infrastructure requires de-risking activities and the development of building blocks, such as standardized interfaces and communication. Mastery of close-proximity operations and docking is essential for the new transportation system. This new branch of space operations represents a good opportunity to introduce more sustainable propulsion solutions, especially given the high costs and uncertain future of hydrazine and its derivatives. IOSHEX, a service spacecraft to be equipped with a green propulsion system utilizing 98% hydrogen peroxide, serves as a reference. This paper presents a design concept for this propulsion system, including trade-off analyses, calculations, and a three-dimensional model integrated with IOSHEX.

Bali Metropolitan Area faces challenges in managing the increasing volume of waste generation. This research was inspired by the need to understand the dynamics behind urban waste production, particularly the role of socioeconomic factors such as the Human Development Index (HDI), income, and education level. The aim of this research is to examine the influence of HDI, income and education level on the volume of waste generation in the Metropolitan Area of Bali. This study aims to identify socioeconomic variables that contribute significantly to waste production, to inform more effective waste management strategies. This study uses multiple linear regression methodology to identify statistical relationships between HDI, income, and education level and the volume of waste generation. This method allows a comprehensive analysis of how each socioeconomic variable influences urban waste production. The research results show that HDI and education level have a significant influence on increasing the volume of waste generation in the area, while income does not show a significant influence. These findings highlight the complexity of the relationship between socioeconomic factors and waste production, as well as the need for a more mature approach in waste generation prediction modeling. This study concludes that improving the quality of human development and education play an important role in waste management strategies, reducing the environmental impact of generation waste in urban areas. These findings support the implementation of comprehensive environmental education programs and suggest more in-depth community surveys and social mapping to develop more effective and sustainable waste management strategies.

The coastal area of Banda Aceh is claimed as a vulnerable area to tsunami, including Meuraxa subdistrict, Peukan Bada sub-district and Jaya Baru sub-districts, which categorized as red zone for tsunami risk. One of the government's structural disaster mitigation efforts is to build the BPBA Evacuation Building in 2016. This study aims to identify the factors that influence community decisions in choosing tsunami evacuation routes to the BPBA Tsunami Evacuation Building at a radius of 2 km and to discover the probability of the community's demand in selecting tsunami evacuation routes based on the width of road. The Stated Preference technique is used to obtain data on factors that influence route selection decisions, which then modeled using the Discrete Choice Model. The data is processed by using binomial logit model, and analized by using Goodness of Fit test. Goodness of fit of the data is selected based on the criteria of logistic regression which consist of Rho square (ρ2) between 0-1, LR test sig ꭓ2 ≤ 5% andt test sig ≤ 5%. The results showed that the factors that influenced the community's decision in choosing tsunami evacuation routes in a 2 km radius from the BPBA evacuation building were age of individual, level of household income, number of car ownership, and type of evacuation route. Type of the evacuation route is assumed as familiar route to individuals. Understanding the factors influencing the individual decision of tsunami evacuation will enhance evacuation efforts and provide equal opportunity for people to reach designated safe zones in time.

Authors: Дыбовский Александр Сергеевич
Published: September 2024

Over the past few decades, the Japanese language has experienced a noteworthy surge in Western loanwords, wherein English has conspicuously impacted the phonetics, graphics, vocabulary, and grammar of contemporary Japanese. In 1980, American cultural anthropologist Herbert Passin foresaw the complete Westernization of the Japanese language in his publication. This article investigates the reasons behind the non-realization of this prediction, exploring issues pertaining to the rivalry between "Western" and proto-Chinese linguistic forms in modern Japanese. Additionally, it scrutinizes the role of Sino-Japanese elements in the written styles and genres of the language.

For accuracy, the proton interaction channels with 100Mo, the excitation functions of reactions,100Mo(p,2n)99mTc, 100Mo (p, pn)99Mo, and 100Mo (p, nonelastic) are calculated, using Kalbach Systematic approach in Exciton model gathered with Feshbach-Kerman-Koonin (FKK) statistical theory. The results are compared with the available published data in the experimental nuclear reaction data (EXFOR) version of November 2022. The comparisons show acceptable results for the maximum cross-section of producing 99mTc at 16 MeV protons. Also, rare data was searched for the reactions, 100Mo (p, p n)99Mo, and 100Mo (p, nonelastic), to compare the present calculated results.
Studying the Physicochemical Properties of Water Activated by Cold Atmospheric Plasma Jet
Authors: Humud Hammad R. , Hameed Tamara A.
Published: September 2024

This research aim is to activate water using a plasma jet that works with argon gas and to study the effect of the plasma on the physicochemical properties of the water. The plasma consists of a power supply capable of supplying a high alternating voltage of up to 12 kV in the form of a sinusoidal wave with a frequency of 20 kHz. The temperature of the produced plasma (Te) was (1.028) eV, and its electron density (ne) was (4.392×1017) cm-3 at a flow rate of 1L/min. The physicochemical properties of the water are determined by determining the concentration of each of NO2, NO3, and H2O2, the pH of the water, and the water temperature during exposure to the plasma. The effect of storage time on the properties of the activated water is determined after 48 hours of exposure to plasma. The RONS species were measured using kits purchased from USA (Bartovation) Company manufactured for this purpose. The pH was measured with a pH meter, and the working gas temperature was remotely measured with an IR thermometer. The concentration of the three active species increases with exposure time, but the active species NO2 concentration decreases to zero at an exposure time of 120 minutes. The concentrations of the three components decrease with the decrease in the flow rate. The pH decreases with the exposure time until it reaches 2, and the temperature increases until it reaches 35oC. The concentration of NO3 increases with the increase of the water storage time. In the case of H2O2, the concentration increases slightly, then after 10 hours it begins to decrease exponentially, reaching a value close to zero after the passage of 48 hours. For NO2, its concentration begins to decrease exponentially from the start of storage and reaches a concentration close to zero after 48 hours of storage. The pH increases with the storage time, and the water reaches its natural state with a pH of 7 after 48 hours of storage. From this, it is concluded that the best storage time for PAW is ten minutes after the end of the activation process, and also that the activation time should be short, but not exceeding ten minutes.

The impact of adopting (IAS 8) accounting policies, changes in accounting estimates and errors on the financial performance An applied study in the (ETT) Company for General Trading Limited operating in the Kurdistan Region
Authors: Jamal Anwer Yaba
Published: September 2024

The study aims primarily to explain the changes that occur in the financial performance of the study company as a result of the application of (IAS 8) accounting policies, changes in accounting estimates, and errors on the financial performance of the study company.
The researcher relied on the deductive approach to complete the study, on the texts of international standards, and on the financial statements of the (ETT) Company for General Trading Limited operating in the Kurdistan Region for the fiscal years (2020, 2021). By applying the three cases adopted by (IAS 8) (accounting policies, accounting estimates, errors) and observing its impact on financial performance. The researcher reached a set of conclusions, the most important of which is that the changes that occur with the expansion in the size of companies and the occurrence of any changes in the nature of their business, undoubtedly create the need for accounting standards that contribute to unifying accounting procedures and work. Thus improving the quality of their results from the financial statements. One of the most important recommendations of the research is the need to limit the freedom that companies enjoy in choosing methods and methods and setting accounting estimates in order to move towards unification in accounting work in accordance with the requirements of international accounting standards.
Measuring the Causal Relationship Between Inflation and Unemployment in Iraq using the Phillips Curve for the Period (2004-2021)
Authors: Gnin Mohammad Salih
Published: September 2024

This study aims to analyze and measure the causal relationship between the inflation rate and the unemployment rate in Iraq for the period during (2004-2021) using the Phillips curve methodology in analyzing the causal relationship between inflation and unemployment rates. The theoretical and applied importance of the study can be reviewed, which stems from the extent of the need for all countries to address the problems of Macroeconomic, represented primarily by the problems of unemployment and inflation. As the Iraqi economy, like other countries, suffers from high rates of inflation and unemployment, and from their many negative effects, whether economically or socially. As we find that there are many intertwined factors behind these two problems. This led to many risks that affected the individual and society, which in turn led to a waste of Iraq’s economic and human potential. Therefore, these two problems must be addressed quickly in order to reduce their repercussions and their ongoing consequences. From this logic, our study came to answer the following question: Is there an inverse relationship between the unemployment rate and inflation in Iraq during the period (2004-2021)?
The study found that the low frequency of the inverse relationship between the inflation rate and the unemployment rate in Iraq for the period (2004-2021) indicates a relative separation in the effect between the change in inflation and unemployment, meaning that a decrease in the unemployment rate by (0.013%) on average is accompanied by an increase in the inflation rate. By 10%, while the correlation coefficient was calculated between the study variables and it was found that there is a direct relationship between them. If it is not possible to achieve the Phillips curve for the period (2004-2021) and the emergence of the so-called pure economic recession, as through this we have reached that there is a slight inverse relationship between the variables. But not for all years of study, and this is consistent with the theoretical aspect of the Phillips curve and what was proven by the mathematical analysis of the study.

Penelitian ini bertujuan untuk : mengetahui Human Capital di PT. Mustika Tembakau Bandung, mengetahui konstribusi kinerja Human Capital di PT. Mustika Tembakau Bandung, mengetahui hasil pengukuran Human Capital dengan menggunakan metode Return On Investment di PT. Mustika Tembakau Bandung.
Metode yang digunakan dalam penelitian ini adalah metode Return On Investment, yaitu suatu perhitungan untuk menentukan jumlah usaha yang diterima dari penanaman sejumlah modal yang berupa uang atau sumber daya. Berdasarkan hasil penelitian dengan menggunakan metode Return On Investment, dapat diketahui untuk karyawan tetap perusahaan mengalami penurunan pada tahun 2022, dimana tingkat pengembalian investasi menurun menjadi 4,37% dari yang sebelumnya 5,12%, sedangkan ke tahun 2023 mengalami peningkatan menjadi 5,18%.  Sedangkan untuk karyawan keseluruhan juga menurun pada tahun 2021 ke 2022 dari 5,03% menjadi 4,44% dan mengalami peningkatan lagi di tahun 2023 menjadi 5,28%.
Dari perhitungan Aspek finansial human capital pada PT. Mustika Tembakau Bandung, dapat diketahui bahwa investasi yang diberikan oleh karyawan kepada perusahaan menunjukan hasil yang positif terhadap perkembangan perusahaan. Akan tetapi masih perlu dilakukan program pengembangan sumber daya manusia yang lebih baik dan efektif karena jika dilihat dari metode Return On Investment walaupun hasilnya positif tetapi terjadi penurunan dari tahun 2021 ke 2022 meskipun penurunannya tidak terlalu tinggi.

DOPPLER EFFECT IN OPTICS
Authors: ИЗБРЕХТ А.Р.
Published: September 2024

В статье рассматривается возможность уточнения классической формулы и формулы СТО для эффекта Доплера в оптике на основании представления о преимущественной инерциальной системе отсчета (ПИСО), связанной с невещественной структурой физического вакуума. Принимается, что электромагнитные волны распространяются в физическом вакууме со скоростью C0 относительно его невещественной структуры. Обосновывается положение о том, что скорость частиц материи, определенная по отношению к космическому микроволновому фоновому излучению (КМФИ) является одновременно и скоростью их движения относительно невещественной структуры физического вакуума, т.е. ПИСО может быть связана и с КМФИ. Так как скорости движения тел относительно КМФИ, а, соответственно, и относительно ПИСО могут быть надежно определены, то, используя классическую формулу для эффекта Доплера и полученную в [5] формулу зависимости частоты излучаемых веществом фотонов от скорости движения вещества относительно ПИСО, можно получить общую формулу для эффекта Доплера в оптике, в которую классическая формула и формула СТО входят как частные случаи. С помощью общей формулы для эффекта Доплера получено соотношение, определяющее относительное смещение спектров источника и приемника излучения в зависимости от скоростей их движения относительно ПИСО.

The paper discusses the possibility of adjusting the classical formula and the SRT formula for the Doppler effect in optics based on the concept of preferential inertial reference frame (PIRF) related to the immaterial structure of a physical vacuum. It is assumed that electromagnetic waves travel in a physical vacuum at speed C0 relative to its immaterial structure. It is substantiated that the speed of matter particles determined relative to the cosmic microwave background radiation (CMBR) is concurrently the speed of their motion relative to the immaterial structure of the physical vacuum, i.e. PIRF may be related to CMBR as well. Since the speeds of bodies in motion relative to the CMBR and, hence, relative to PIRF can be determined reliably, then using the formula correlating to the frequency of photons irradiated by a substance and speed of the substance motion relative to PIRF, which was obtained in [5], and the classical formula for the Doppler effect, one can deduce a general formula for the Doppler effect in optics that includes the classical formula and the SRT formula as in particular cases. With the help of the deduced general formula for the Doppler effect, the correlation was deduced, which determines the relative shift of spectra of the source and receiver of radiation depending on the speed of their motion relative to the PIRF.
REACTIVE ELECTRODYNAMICS OF UNCLOSED CONDUCTORWITH ALTERNATIVE CURRENT

Ток смещения, возникающий между концами незамкнутого проводника, замыкает ток проводимости, что позволяет переменному току течь в незамкнутом проводнике. Учет пондеромотороного воздействия магнитного поля только на ток проводимости приводит к появлению так называемой силы самодействия, что нарушает закон сохранения импульса. Для того, чтобы закон сохранения импульса выполнялся, необходимо учитывать импульс, передаваемый переменному электро-магнитному полю. Сила Абрагама, которая, формально говоря, представляет собой силу, с которой переменное магнитное поле действует на ток смещения, полностью компенсирует силу самодействия. Эту силу можно рассматривать как реактивную, посредством которой незамкнутый проводник с переменным электрическим током должен отталкиваться от поля. Для бесконечно тонкого проводника эта сила может быть экстремально большой.

Displacement current between ends of an unclosed conductor closes the conduction electric current that means that the alternative current can flow in the unclosed electric contour. Accounting the ponderomotive action of the magnetic field on the conduction current only leads to appearance of the so called self-force violating the law of conservation of momentum. In order to conserve the momentum one needs to take into account the hidden momentum transferred to the alternative electromagnetic field. The Abraham force is the force with which, formally speaking, the alternative magnetic field acts on the displacement current compensating the self-force. One may consider such a force as a reactive one by means of which the unclosed electric contour repulses the field. When the electric circuit is infinite thin, this force can be extremely large.
ON THE MECHANISMS OF FORMATION OF FINELY DISPERSED SOLID WASTE AT EXPLOSIVE CRUSHING OF ORES AND ROCKS

На современном уровне нашего технологического развития на основе вещества и энергии, извлекаемых почти исключительно из литосферы, ведущее место в образовании мощного потока минеральной пыли, загрязняющей атмосферу и биосферу, занимает взрывное дробление горных пород. Важной особенностью развития процессов в ближней от заряда зоне, создающей дополнительные энергетические предпосылки для сверхтонкого разрушения материала, является эффект вторичного дробления в результате смены механизма разрушения. При значительных деформациях среды вблизи зарядов ее разрушение происходит, как на динамическом фронте дробления, так и при последующем деформировании дезинтегрированной среды. Основным приоритетом при создании модели распределения и потребления энергии взрыва в горном массиве является определение количественных и качественных показателей дробления материала в прилегающей к зоне экстремальной концентрации энергии. Выполнен комплекс теоретических исследований по изучению характера и особенностей распределения и поглощения энергии взрыва в полиминеральных геологических материалах. Установлено, что разрушение этих материалов на фронте дробления по мере удаления от центра заряда происходит по различным механизмам. При этом определяющее значение имеют не столько интегральные свойства массива, сколько его минеральный состав, через соотношение размеров и прочности зёрен породообразующих минералов.

At the present level of our technological development on the basis of matter and energy extracted almost exclusively from the lithosphere, the leading place in the formation of a powerful stream of mineral dust polluting the atmosphere and the biosphere, is explosive fragmentation of rocks. An important feature of the development of processes in the nearcharge zone, which creates additional energy conditions for ultra-thin destruction of the material, is the effect of secondary crushing as a result of the change of the mechanism of destruction. With significant deformations of the medium near the charges, its destruction occurs both on the dynamic front of the crushing and the subsequent deformation of the disintegrated medium. The main priority in creating a model of distribution and consumption of explosion energy in the rock mass is to determine the quantitative and qualitative indicators of crushing material in the area adjacent to the extreme energy concentration. The complex of theoretical studies on the nature and characteristics of distribution and absorption of the energy of the explosion in polymineralic geological materials. It is found that the destruction of these materials at the crushing front as the distance from the center of the charge occurs by various mechanisms. In this case, the determining value is not so much the integral properties of the massif as its mineral composition, through the ratio of the size and strength of the grains of rock-forming minerals.
