Evolusi Konstruksi Agama di Indonesia: Sinkretisme dan Koeksistensi dalam Lanskap Keagamaan
Authors: Latief Hilmy Abdul , Yacobus Ari Respati
Published: July 2024

Evolusi arsitektur keagamaan di Indonesia mencerminkan perjalanan yang panjang dan dinamis, dari masa prasejarah hingga era modern. Pada periode awal, kepercayaan animisme dan politeisme tercermin dalam struktur megalitik, sementara pengaruh Hindu-Buddha terlihat jelas dalam keagungan candi-candi seperti Borobudur dan Prambanan. Kedatangan Islam membawa transformasi besar, memperkenalkan masjid-masjid yang memadukan elemen arsitektur lokal dan prinsip Islam, seperti yang terlihat pada Masjid Agung Demak dan Masjid Menara Kudus. Era kolonial membawa pengaruh arsitektur Eropa yang berbaur dengan tradisi lokal, menghasilkan bentuk-bentuk hibrida yang unik. Di era modern, arsitektur keagamaan di Indonesia terus berkembang dengan mengintegrasikan nilai-nilai keberlanjutan dan efisiensi sambil tetap menghormati warisan budaya dan spiritual yang kaya. Selain itu, Indonesia juga mempromosikan moderasi beragama melalui pendidikan dan kebijakan sosial untuk menjaga kerukunan dalam masyarakat yang multikultural. Bangunan keagamaan di Indonesia berfungsi tidak hanya sebagai tempat ibadah tetapi juga sebagai simbol integrasi budaya dan inovasi modern. Secara keseluruhan, arsitektur keagamaan di Indonesia mencerminkan interaksi harmonis antara pengaruh eksternal dan kekayaan lokal, menjadikannya cerminan dari dinamika sejarah dan budaya yang kaya di Indonesia.

Published: July 2024

The experiment was carried out in the Teaching and Research Farm of the Department of Animal Science, Faculty of Agriculture Usmanu Danfodiyo University, Sokoto, Nigeria, to determine the effects of dietary oregano leaf powder on meat quality of broiler meat. The diets were supplemented with oregano leaf powder at 15g/kg, 20g/kg, 25g/kg and 0g/kg (control group), represented as TI, T2, T3 and T4, respectively, dietary oregano leaf powder did not affect muscle pH a* values of broiler meat (P>0.05). However, oregano leaf powder significantly affected b* value, water holding capacity, drip and cooking losses. Higher inclusion level (25g) of oregano leaf powder improves meat quality parameters while supplementation of up to 15g did not affect most of the meat quality parameters. The study recommended 25g inclusion levels of oregano leaf powder due to the positive effects on meat quality parameters of broiler chicken meat. Further studies on the mode of action of oregano leaf powder using different species of poultry on meat quality may be commercially interesting.

Authors: Pham Le Trinh Viet , Ngo Hang Thi
Published: July 2024

The paper investigates the impact of foreign ownership on the stock return volatility of financial firms in Vietnam. Applying panel regression models on a year-end research sample of 23 banks and financial firms listed on stock exchanges in Vietnam from 2017 to 2022, the study assures the negative relationship between foreign ownership and the stock return volatility, implying that increasing foreign ownership reduces the volatility of stock returns of financial firms. Our study’s novelty is reflected in following aspects. First, our study, examining about the foreign ownership's impact on stock returns’ volatility in emerging stock market conditions, will enrich this research field by contributing additional empirical evidence to the field through a concrete and well-designed research. Additonally, our research findings not only provide useful information about the volatility of those influential shares in mentioned industries coupled with its determinants but also support investors and policymakers in making investment decisions informedly as well as reviewing suitable regulations for investors and capitals from foreign countries, which is a critical aspect in helping Vietnam's stock market to expand more steadily and sustainably.
THE EMERGENCE OF WOMEN AS HISTORICAL SUBJECTS: DECONSTRUCTING THE HISTORY OF SPAIN FROM TEXTBOOKS
Authors: Peinado Rodríguez Matilde
Published: July 2024

The work we present is not an analysis of the presence of women in textbooks, a very fruitful historiographical line from which magnificent works have been published in recent years. The methodology is logical-argumentative and qualitative, where the written and visual contents of the textbooks are the pretext to rethink/deconstruct History in the light of the gender perspective. We start from an evolutionary analysis of the presence of women in the current manuals of History of the second year of Baccalaureate, for the period from 1931 to 1975, to understand the keys to the inclusion/exclusion of the female collective in the historical narrative and to propose how the conception of citizenship present in the LOMLOE can become a challenge and an opportunity to rethink and, Consequently, to rewrite a subject that continues to be largely articulated from androcentrism, patriarchy and classism, although its main mission is to develop the critical thinking of students and prepare them to think historically and act socially. We present, for this, a conceptual proposal that necessarily starts from an epistemological deconstruction of history as a science. For this, we have taken as a reference a representation of the research published in recent years that make visible the significance of women in the historical story, with the aim of outlining the thematic lines that allow us to move towards history free of androcentric and patriarchal biases, where women are integrated and made visible as historical subjects.

Despite the fact that most people are aware of contemporary contraceptives, there is still a significant unmet need for family planning. Therefore, this study evaluated the variables linked to Ugandan women of reproductive age using contemporary contraceptives. Data from a cross-sectional 2016 Uganda Demographic and Health Survey was used in this study. The study employed quantitative approach where descriptive statistics were used to summarize the characteristics of the respondents and a random intercept model was run. This study found that women of reproductive age used contemporary contraceptives on average at a rate of 27.3% (95% CI: 26.3, 28.3), women aged 25 to 29 made up the largest percentage of users (AOR = 1.38, 95% CI: 1.10, 1.73), while those aged 15 to 19 made up the smallest percentage of users yet it is the most sexually active age bracket. Very few Ugandan women of reproductive age used contemporary contraceptives on a regular basis. This low rate was attributed to a variety of woman, household, and community factors, including age of the mother, education level (mother and husband), employment status of the mother, ever had a pregnancy terminated, access to television, frequency of internet use, possession of a personal phone, last birth being caesarean, wealth quintile, sex of household head, religion, and region, all of which were significantly associated with the use of modern family planning. Therefore, while pushing the shift to the use of contemporary contraceptives, all these issues must be taken into account.

A musical genre is a term used to classify specific musical styles in accordance with a sense of their significance or a set of guidelines. There are many techniques to classify music into different genres, but attempts to automate this process using machine learning have received much less attention from the media. Blues, Classical, Country, Disco, Hiphop, Jazz, Metal, Pop, Reggae and Rock are the most common musical genres. Objective: This study develops and creates a model that can classify music into their respective genre. The dataset, which contains 1000 songs divided into 10 sections with 100 songs each, was obtained from the open-source service "Kaggle" and utilized for the classification. To train and test the model, the dataset was then converted into a JSON format, the new dataset was then splitted into 30% for testing the model and 70% for the training of the model. This model was created using the Convolutional Neural Network (CNN) machine learning technique. The result shows that the model was able to correctly classify 7 audios out of 10 audios and correctly classify them into their original genre. The classifier achieved an accuracy score of about 73%. In conclusion, the study provided a model that will aid in the classification of various types of music into their appropriate genres. This will be highly useful for record companies and other music retailers to group songs for search and retrieval.

The influence of leverage on accrual-based and real earnings management: Evidence from the UK
Authors: Al-Shattarat Basiem
Published: July 2024

The crucial aim of this study is to observe the association between leverage and earnings management using accrual-based earnings management (AEM) and real earnings management (REM) practices among the firms listed on the London Stock Exchange. To keep unobservable elements under control, this study employs a Two-Stage Least Squares approach to analyse data from UK-listed firms for the years 2009-2020. The findings reveal that there is a significant negative association between leverage and earnings management through REM but not through AEM. The results are aligned with the premise that leverage works towards limiting REM activities, which eventually influences the accounting earnings quality. Therefore, high leverage calls for debt repayment to minimise the available cash for management’s non-optimal spending, depending on the lender-induced spending limitations. Further, this is predicted to minimise managers’ opportunistic behaviours and encourage their conservativeness. The study findings have implications for the regulatory and stock market players as it provides in-depth information concerning current practices in accounting and reporting.

El objetivo crucial de este estudio es observar la asociación entre el apalancamiento y la gestión de beneficios mediante prácticas de gestión de beneficios basadas en el devengo (AEM) y gestión de beneficios reales (REM) entre las empresas que cotizan en la Bolsa de Londres. Para mantener bajo control los elementos no observables, este estudio emplea un enfoque de mínimos cuadrados en dos etapas para analizar los datos de las empresas que cotizan en el Reino Unido durante los años 2009-2020. Los resultados revelan que existe una asociación negativa significativa entre el apalancamiento y la gestión de beneficios a través de REM, pero no a través de AEM. Los resultados concuerdan con la premisa de que el apalancamiento contribuye a limitar las actividades de REM, lo que a la larga influye en la calidad de los beneficios contables. Por lo tanto, un apalancamiento elevado exige el reembolso de la deuda para minimizar el efectivo disponible para gastos no óptimos de la dirección, en función de las limitaciones de gasto inducidas por el prestamista. Además, se predice que esto minimiza los comportamientos oportunistas de los directivos y fomenta su conservadurismo. Las conclusiones del estudio tienen implicaciones para los agentes reguladores y bursátiles, ya que proporciona información en profundidad sobre las prácticas actuales en materia de contabilidad y presentación de informes.
KINETIC CHARACTERISTICS OF THERMOLYSIS PROCESSES OF WASTE RUBBER PRODUCTS
Authors: Makarevich Evgeniya A. , Papin Andrey V. , Cherkasova Tat’yana G.
Published: July 2024

In this paper, the kinetic parameters of various stages of the processes occurring during the thermal decomposition of waste rubber products are determined. To study the physico-chemical and chemical transformations occurring in waste samples of rubber products with temperature changes, a thermal analysis was carried out. It has been established that the processes of thermal destruction of the carbon component of rubber products are similar to the processes occurring during pyrolysis of solid natural combustible minerals, and conditionally consist of four stages. On the basis of the derivatogram, the temperatures of the endothermic minima were determined, and the temperatures of the processes were determined from the beginning of the peaks of the effects on the DTA curve. To determine the kinetic parameters of various stages of the process of thermal destruction of rubber products without air access, the Arrhenius law was used as the initial equation, which describes the dependence of the reaction rate constant on temperature. It is established that a first-order kinetic equation is acceptable for the process of thermal decomposition of waste rubber products during pyrolysis, activation energies and pre-exponential multipliers of each stage of thermal decomposition are calculated. The lowest reaction rate is observed in the temperature range of 510-780 °C, respectively, this stage is limiting and determines the rate of the process. Based on the results of thermal analysis, a method has been proposed and developed that allows to obtain a refined solid carbon-containing pyrolysis residue by calcining it at a temperature of 800-850 °C in an oxygen-free environment until the complete cessation of gas emission processes. The data obtained are necessary for modeling the pyrolysis process of rubber products on a production scale. Based on laboratory studies and experimental data obtained, it is possible to optimize existing pyrolysis plants for rubber waste.

PLASMA PARAMETRS AND SILICON ETCHING KINETICS IN CF4 + C4F8 + O2 MIXTURE: EFFECT OF CF4/C4F8 MIXING RATIO
Authors: Efremov Alexander M. , Bobylev Alexander V. , Kwon Kwang-Ho
Published: July 2024

In this work, we investigated the influence of fluorocarbon component ratio in the CF4 + C4F8 + O2 gas mixture on electro-physical plasma parameters, steady-state densities of active species and silicon etching kinetics under typical reactive-ion process conditions. The combination of plasma diagnostics (double Langmuir probes, optical emission spectroscopy) and plasma modeling confirmed known peculiarities of plasma chemistry of individual fluorocarbons in the presence of oxygen as well as provided an extended analysis of both fluorine and oxygen atom kinetics in the three-component gas mixture. It was shown that the substitution of CF4 by C4F8 at the constant fraction of O2 a) causes the weak disturbance in electrons- and ions-related plasma parameters (electron temperature, electron density, ion energy flux); b) provides drastically increasing density of polymerizing CFx (x = 1, 2) radicals; and c) results in monotonically decreasing F atoms density. The latter is due to simultaneous changes in both F atom formation rate and their loss frequency, especially in C4F8-rich plasmas. From experiments, it was found that Si etching rate is by more than 85% controlled by its chemical component (in a form of ion-stimulated heterogeneous reaction Si + xF → SiFx) and decreases with increasing C4F8 fraction in a feed gas. The change in effective reaction probability contradicts with the growth of polymer deposition rate and film thickness (as it follows from changes in gas-phase plasma characteristics) but may reflect the weakening of surface passivation by oxygen atoms.

Authors: Kataeva Natalia N. , Naronova Natalia A. , Golitsyna Kristina O. , Belokonova Nadezda A. , Shulepova Ksenia E.
Published: July 2024

As a part of the study, a comparative analysis of different generations three representative’s lipophilic properties of cephalosporin antibiotics, namely cefazolin, cefotaxime and cefepime, was carried out. Lipophilicity is a very important physicochemical property of medicinal substances, since it determines their ability to pass through protective barriers, distribute, accumulate in tissues and body fluids, be broken down and excreted, which, in turn, affects the manifestation of antibacterial activity and the cytotoxic effect of antibiotics. During the experiment, a series of drugs aqueous solutions were prepared, then the antibiotics were extracted with highly purified olive oil, after which the aqueous phase was taken and the osmolality value for it was determined. Based on the calibration dependences of the osmolality value on the concentration of the antibiotic in the aqueous phase after extraction, the logarithms of the distribution coefficients in the «oil/water» system were calculated, which is a numerical indicator of the lipophilicity of substances. Using the capabilities of the online platform «Molinspiration Cheminformatics Software», the theoretical values of the studied drugs distribution coefficients logarithms were also determined, and the theoretical values correlated with the experimental ones. Based on the data obtained, it was revealed that the studied antibiotics have low lipophilicity, which decreases in the order: cefotaxime > cefazolin > cefepime. The work also assessed the relationship between solution pH and lipophilic properties. Pearson's r-coefficients between pH and antibiotic concentrations in oil after extraction of cefotaxime and cefazolin show a weak inverse relationship between the studied parameters. For cefepime solutions, a similar linear correlation coefficient demonstrates a direct high relationship between the pH of the solution and the lipophilicity of the antibiotic. The results of the study can be taken into account during antibiotic therapy with appropriate cephalosporins, as well as when creating a new generation of antibiotics.

Published: July 2024

French bean (Phaseolus vulgaris L.), a type of common bean, is an important legume vegetable crops grown for its tender pods, and is also known as snap bean, garden bean or vegetable bean. The pods of French beans (green, yellow and purple in colour) are harvested when they are rapidly growing, fleshy, tender (not tough and stringy), bright in colour, and the seeds are small andunderdeveloped (8 to 10 days after flowering). After that period, excessive seed development reduces quality and the pod becomes fibrous, pithy and tough, and loses its bright colour (Singh and Singh 2015).

Master B as foliar nutrients application with boron, manganese, and zinc at shooting, flowering, and podding stages. The results showed that foliar application of micronutrient (boron, manganese, andzinc) at all three stages enhanced most vegetative growth characters, shelling ratio, seed yield and its components, seed germination percentage, chlorophyll leaf contents and seed protein content. It was found that the foliar application of boron, manganese, and zinc at three stages of growth seemed to be the best effective treatment for more robust vegetative growth and seed yield and quality enhancement.

The experiment was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar (Haryana) to find out the effect of high RSC water, farmyard manure and gypsum on growth and phenological parameters in radish field during the year 2017- 18 & 2018-19. The treatments comprising of three levels of farmyard manure (0, 10 and 20 t/ha) and three levels of gypsum (0, 50 and 100% neutralization of RSC) were laid out in a randomized block design (factorial) with thrice replicationkeeping a net plot size of 3.0x3.0 m and Punjab Safed cultivar was used for this study. The application of farmyard manure individually and in combination of farmyard manure and gypsum significantly influenced the vegetative growth and phenological parameters in radish crop under semi-arid conditions of Hisar. Among the interaction combinations, the plant height at 80 days after planting (cm) and at harvest (cm), number of leaves per plant at 80 days after planting, number of primary and secondary branches per plant at harvest were recorded significantly maximum in F2G2 treatment where farmyard manure was applied at the rate of 20 t/ha in combination with 100% neutralization of RSC by gypsum. However, minimum days to 50% flowering, days to 50% pod formation and days to maturity were recorded in F0G0 treatment combination where no farmyard manure and gypsum was applied during 2017-18 and 2018-19.

Six different isolates of Sclerotinia sclerotiorum were isolated from vegetable host crops namely brinjal, cauliflower, French bean, and pea on potato dextrose agar. These isolates were subjected for morphological characterization, cross infectivity/pathogenicity test andchemo-sensitivity towards bioagent and new molecules of fungicides. On the basis of morphological characteristics viz., colony colour and texture, the tested isolates were categorized into two groups. Cross infectivity / pathogenicity test were performed on French bean, dolichos bean and pea using leaf detachment technique. Results on cross infectivity revealed non-host specificity of tested isolates of the pathogen. As regards to chemo- sensitivity of these isolates with tebuconazole 250 EC, azoxystrobin 23 SC, fluopyram 17.7+ tebuconazole 17.7 SC, Fluopicolide 6.25 %+Propamocarb Hydrochloride 62.5% SC at concentration of 250, 500, 1000 and 1500 ppm, the combination fungicide fluopyram 17.7+ tebuconazole 17.7 SC was found most effective at concentration of 250 ppm against tested isolates of S. sclerotiorum. In case of in vitro evaluation of bioagent, Trichoderma asperellum against these isolates, the highestmycelial growth inhibition (50.46%) against pea isolate (PSS- 1) and the lowest inhibition (26.15%) in case of French bean isolate (BSS-1) was observed. Cross infectivity and chemo sensitivity of the pathogen clearly indicate the emergence of this pathogen as broad spectrum covering wide host range.

In the present experiment three levels each of plant growthregulators (NAA, GA3, Ethrel) and trace elements (ZnSO4,MnSO4, Boric acid), respectively, were sprayed at secondand fourth leaves stage along with control treatment onbottle gourd plants to find out their effect on fruit yield. Thestudy was conducted at Research Farm of the Departmentof Vegetable Science, CCS, Haryana Agricultural University,Hisar during Spring summer season of 2017-18. The resultsof the study clearly indicated that application of Ethrel 200ppm significantly increased the fruit yield and its relatedattributes over control treatment. The spraying of Ethrel200 ppm significantly reduced the length of internodes (11.7cm), node number to bear first female (7.3), number ofstaminate flowers per plant (104.3), length of internodes(11.7) as well as main vine length (357.2 cm) whereas itincreases number of primary branches /vine (17.7), thenumbers of pistillate flower per plant (17.0), longest fruitlength & diameter (32.9; 7.5 cm), length of pedicel (15.9 cm),number of fruits per vine (7.7) and fruit yield per plot and perhectare (30.1 kg and 361.1 q), respectively. Whereas, thespray of GA3 75 ppm delayed the node number to bear firstfemale flower (15.3) and increased the number of staminateflowers per plant (145.7) and length of internodes & mainvine length (16.7 and 487 cm) as well as it decreased thenumber of pistillate flowers per vine (9.3) and fruit yield perplot and per hectare (19.8 kg, 237.6 q). The highest nodenumber to bear first male flower (13.3) and maximum numberof days to opening of first male flower (54.7) were recordedin treatment NAA 300 ppm. From the study, it was concludedthat bottle gourd plants of cv. GH-22 when sprayed withEthrel 200 ppm produced the maximum fruit yield (361.1q/ha).

The production of fruits and vegetables in India aregrowing at compounded annual rates of 5% and 6%,respectively over the past decade (Singh 2019). So faras its contribution to Indian economy is concerned, fruitsand vegetables are grown only on 7–8% of gross croppedarea but contribute more than 18.8% of the gross valueof agricultural output and 52% export earnings from totalagricultural produce (Singh 2019). Although, India is thesecond largest producer of vegetables and third largestproducer of fruits with annual production of 141 and 80million tones, respectively, it is estimated that 20 -30percent of horticultural crop such as fruits and vegetablesperish due to lack of proper methods of processing andstoring. The loss in monetary term is estimated to beabout Rs.20 crores annually. It is also estimated thatonly 2% fruits and vegetables produced in our countryis being processed (Singh 2019).

India is considered as the domestication center for eggplant and its diverse germplasm is notable. In present study, 84 germplasm lines including 79 breeding lines of cultivated eggplant along with five wild species were differentiated on the basis of 21 morphological trait descriptors and 40 simple sequence repeat (SSR) markers. According to principle component analysis (PCA) of morphological traits, 70.33% of the total variation was explained with first 8 PCs. Out of 40 SSR markers, only 19 (50-100%) revealed polymorphism among various cultivated and wild genotypes with a range of 2 and 10 alleles and a mean of 4.9 alleles per marker. Onthe basis of PIC values and number of amplified alleles per marker, EEMS28 was the highest polymorphic marker, which was followed by CSM31 and CSM27. Jaccard’s similarity coefficient among genotypes varied from 0.38 -0.98 being the highest between cultivated genotypes and S. torvum. The morphological and SSR data were analyzed individually as well as combined using UPGMA cluster analysis. Morphogenetic divergence within the cultivated eggplant highlighted the possibility of their use in future breedingprogrammes. Wild species diverged into separate group on the basis of SSRs data, but merged into small round group of cultivated eggplant morphologically as well as morphogenetically.S. laciniatum and S. aethiopicum were more close to the cultivated eggplant and can be used in introgression breeding.

This scientific work provides a comparison and analysis of the quality and hygiene requirements of raw cow’s milk obtained from individual producers of large and small farms in three regions of Pelagonia in accordance with the Rulebook on requirements for quality, safety and hygiene of milk. The examinations include analysis of the parameters of the chemical composition, determination of the number of somatic cells and total number of bacteria from milk samples taken throughout the year from small and large farms. The best results (p<0.05) for the protein content are observed in the milk coming from small and large farms from the Southern part of the Pelagonia region, compared to the Northern part of the Pelagonia region and Prilep region. The amount of dry fat-free matter in the milk from small farms in all three regions did not show a statistically significant difference (p<0.05). The results for the lactose content of milk from all three examined regions are within the limits of the Rulebook for raw milk. A significant difference (p<0.01) was found for the content of somatic cells in small farms. It is noteworthy that small farms deviate significantly from the safety and hygiene requirements outlined in the Rulebook, primarily due to the hygiene practices concerning dairy cows. The results obtained will be valuable for the dairy industry, as they will identify weaknesses among domestic producers. Professional services will implement measures and activities to help farmers meet EU standards in milk production. Additionally, these findings will provide a significant basis for establishing strategies in this agricultural sector.
