Authors:   Institute for Oil and Gas, Azerbaijan Republic, Allakhverdiyeva R.G.
Published: June 2023

Influence of the electrical current fields and various type solutions of the surface-active substances on an interfacial tension, adsorption, desorption and on oil recovery factor from heavily clay porous medium has been investigated in the article. Nonionic alfenol, cation-active DMABACH (Dimethyl Alkyl Benzyl Ammonium Chloride) and anion-active sulfonic acid have been used as SAS. Quartz sand and rock from surface exposure of Kirmakian Suite (KS) of Balakhany field are as an adsorbent. It was revealed that direct and alternating current at 50 and 100 V through solutions of different type of SAS doesn’t practically influence on their interfacial tension on the boundary of nonpolar hydrocarbon liquid. Direct and alternating current through the porous medium containing clays and carbonates doesn’t influence on value of dynamic adsorption of nonionic SAS but promotes a decrease of their desorption from the rocks surface. It was determined that shared use of the direct-current field and solution of nonionic surface-active substance in comparison with mineralized water doesn’t practically influence on value of the oil recovery factor due to high adsorption of its molecules on surface of the heavily clay rock of Kirmakian suite. The use of direct current at 100 V considerably allowed (up to 23 %) to increase the Kirmakian oil recovery factor by the stratal alkaline water

There is enough research work on the effective use of non-hydrocarbon gases in order to increase the component recovery of hydrocarbon deposits. Over a long period, we have also carried out a number of research works on the effect of nitrogen and carbon dioxide on the final condensate recovery factor of fields, as well as on the productivity of gas condensate wells. However, it is known that the formation systems of gas condensate fields, along with other non-hydrocarbon gases, contain nitrogen and carbon dioxide. Sometimes their number has a rather large share in the total volume. But, the effect of the amount of nitrogen and carbon dioxide naturally present in reservoir systems on the final condensate recovery coefficient of gas condensate fields has not been studied enough. The influence of the amount of nitrogen and carbon dioxide in the composition of reservoir systems on the condensate recovery coefficient of gas condensate fields has been studied. To this end, a multicomponent hydrodynamic model of the Bulla-Sea field was used as a base case, the factors influencing the process were studied by comparing the final condensate recovery coefficient of the field with other systems containing nitrogen and carbon dioxide.

Authors:   Institute for Petrochemical Processes, Azerbaijan Republic, Javadova M.N.
Published: June 2023

The field of organic synthesis (plastics, synthetic detergents, rubbers, etc.) is based on the processing of olefins and diolefins - pyrolysis products. As demand for basic petrochemical products increases worldwide, so does the need for pyrolysis feedstock itself, and today one of the problems of pyrolysis plants is to provide them with feedstock. Currently, the amount of raw materials supplied to the pyrolysis unit EP-300 of the Sumgayit petrochemical complex is several times lower than the needs of the plant, and incomplete loading of the plant with raw materials negatively affects the cost of the main products of the process: ethylene and propylene, and ultimately on the performance of the entire industry. Therefore, the possibility of using low-quality gasoline fractions of the processing of heavy oil residues, including gasolines from coking and hydrocracking of tar, as a raw material for pyrolysis, as well as the effect of process intensification on production efficiency were studied.

This research was motivated by the existence of several siri marriage couples who registered their marriages with the KUA. There was one siri marriage couple that the author managed to interview, and found data that the couple remarried at the KUA after they had previously conducted a siri marriage first. The purpose of writing this article is to examine the pros and cons in the view of the Head of the KUA in Temanggung Regency regarding remarriage after siri marriage. This research is field research or Field Research, using a qualitative descriptive approach, in which the author conducts observations and interviews directly with the Head of the KUA in Temanggung Regency. The result of the research is that there are differences of opinion about remarriage after siri marriage in the view of the Head of the KUA in Temanggung Regency. Some argue that there is no problem with the implementation of remarriage after siri marriage on the grounds that basically siri marriage is a marriage that is not valid according to the state so that the perpetrator of siri marriage is considered never married as long as the marriage has not been recorded by an authorised official. And there are those who disagree with the existence of remarriage, because there is another alternative, namely isbat nikah. Meanwhile, in the context of tajdīdu'n-nikāḥ (renewing marriage) according to most scholars, the law is permissible. This research is expected to open the insights of all parties that in addition to remarriage, isbat nikah also has an important role in alternative solutions to the problem of nikah siri.

Authors: Jaiswal Sushma , Pandey Manoj Kumar
Published: June 2023

In this paper, blind image watermarking is proposed for grey-scale images using LWT and Arnold maps. A comprehensive analysis of robustness and imperceptibility for different sub-band is analyzed, and a robust sub-band against different attacks is determined for designing a system robust against intentional attacks or combined attacks. The importance of embedding a watermark in several sub-bands has been examined to increase the robustness against various image attacks while retaining a reasonable level of imperceptibility. During the study, robustness is analyzed and watched against the number of attacks such as compression attacks, noisy attacks, de-noising attacks, and geometric attacks. It is moreover seen that higher sub-bands are seen to offer good imperceptibility, and robustness performance depends on the nature of attacks. It has also been noticed that entire attacks affect the watermarked image in a different way. A standard image dataset is used to test the suggested concept, and it is discovered that sub-band 1 performs admirably for strength (robustness) and imperceptibility against different image attacks.

Objective: BRAF activating mutations represents approximately 10% colorectal cancer (CRC) patients who are associated with a poor prognosis in stage II, III and IV. Therefore, to better understand the antitumor effects of Selumetinib in BRAF V600E -mutated CRC, gene set enrichment analysis (GSEA) of gene expression profile of BRAFV 600E - mutated HT-29 cells treated of Selumetinib is proposed in this study. Methods: The differentially expressed genes across the comparison of groups of non- treated and treated of Selumetinib in BRAF V600E -mutated HT-29 cells were analyzed by GSEA. Results: We identified the significant pathways of DNA dependent DNA replication, DNA replication, regulation of DNA replication, cell activation, leukocyte activation, receptor complex, endoplasmic reticulum membrane, RNA processing, RRNA processing, amino acid transmembrane transporter activity, nucleolar part, ribonucleoprotein complex, ribosome biogenesis and assembly and regulation of protein modification process for the upregulated genes and the significant pathways of response to hypoxia, response to extracellular stimulus, ATPase coupled to transmembrane movement of ions, ATPase coupled to transmembrane movement of ions phosphorylative mechanism, lipase activity, MAP kinase activity, phospholipase activity and actin filament for the downregulated genes relevant to resistance of Selumetinib in BRAF V600E - mutated HT-29 cells. Our data revealed that GLI2, IL8, LAT2, ICOSLG, TLR4, SPINK5, HDAC4, LAT and TGFB1 are the upregulated important genes and PDIA2, TGFB2, GIPR and GCGR are the importantly downregulated genes associated with resistance of BRAF V600E -mutated HT-29 cells to Selumetinib. Conclusion: We identified the upregulated and/or downregulated genes significantly associated with the resistance of Selumetinib in BRAF V600E -mutated HT-29 cells. These top upregulated and/or downregulated genes have significant value in prediction of sensitivity of CRC patients to Selumetinib and in identification of effective combination strategy for treatment of CRC patients.

Method The study was conducted from the government’s perspective and within a time frame of three years from 2017 to 2020. Scale Up Nutrition’ framework for nutrition was used as a reference for the study and an activity-based costing method was applied. Nutrition expenditure was principally categorized into nutrition specific or sensitive spending. Data was collected via public expenditure settlement reports in government portals. Consultation meetings with related stakeholders were conducted to verify the data. Results Spending on nutrition during 2017-2020 from the central budget accounted for 0.03% of total general government spending at national level, while they ranges from 0.04% to 2.25% at sub-national level. Provinces in remote areas and with higher prevalences of stunting in under-5-year-old children tended to have higher nutrition spending. The average government spending on nutrition per capita was estimated at VND80 per capita annually, which accounted for 0.0001% of gross domistic product per capita or 0.0011% of government spending on health. The expenditure for nutrition-sensitive activities was dominant (92%-97%) of the total nutrition expenditure. Conclusion Government spending on nutrition in Viet Nam was very limited during 2017-2020.

Authors: Zhao Hua , Xin Yue , Gao Jinwu , Gao Yin
Published: June 2023

Power-barrier option is a typical exotic option formed by attaching some restrictions to the power option, where the power option evolves from standard European option with the strike price and underlying good price attached to some power. Compared with the ordinary options, power-barrier option can provide investors with stable leverage and premium income. Therefore, power-barrier option is more favored by investors. This paper mainly discusses the pricing problems of power-barrier option in uncertain financial market. The fluctuation of stock price is regarded as an uncertain process and the interest rate is floating. The uncertain differential equation is invoked to simulate this fluctuation in an uncertain environment. Then, the clear pricing formulas of power-barrier option are given. Finally, the corresponding numerical examples and a real data example are put forward to illustrate the method.

In this paper, we study the output tracking control problem based on the event-triggered mechanism for cascade switched nonlinear systems. Firstly, an integral controller based on event-triggered conditions is designed, and the output tracking error of the closed-loop system can converge to a bounded region under the switching signal satisfying the average dwell time. Secondly, it is proved that the proposed minimum inter-event interval always has a positive lower bound and the Zeno behavior is successfully avoided during the sampling process. Finally, the numerical simulation is given to verify the feasibility of the proposed method.
MLSFF: Multi-level structural features fusion for multi-modal knowledge graph completion
Authors: Zhai Hanming , Lv Xiaojun , Hou Zhiwen , Tong Xin , Bu Fanliang
Published: June 2023

With the rise of multi-modal methods, multi-modal knowledge graphs have become a better choice for storing human knowledge. However, knowledge graphs often suffer from the problem of incompleteness due to the infinite and constantly updating nature of knowledge, and thus the task of knowledge graph completion has been proposed. Existing multi-modal knowledge graph completion methods mostly rely on either embedding-based representations or graph neural networks, and there is still room for improvement in terms of interpretability and the ability to handle multi-hop tasks. Therefore, we propose a new method for multi-modal knowledge graph completion. Our method aims to learn multi-level graph structural features to fully explore hidden relationships within the knowledge graph and to improve reasoning accuracy. Specifically, we first use a Transformer architecture to separately learn about data representations for both the image and text modalities. Then, with the help of multimodal gating units, we filter out irrelevant information and perform feature fusion to obtain a unified encoding of knowledge representations. Furthermore, we extract multi-level path features using a width-adjustable sliding window and learn about structural feature information in the knowledge graph using graph convolutional operations. Finally, we use a scoring function to evaluate the probability of the truthfulness of encoded triplets and to complete the prediction task. To demonstrate the effectiveness of the model, we conduct experiments on two publicly available datasets, FB15K-237-IMG and WN18-IMG, and achieve improvements of 1.8 and 0.7%, respectively, in the Hits@1 metric.

Published: June 2023

Sorghum is the most important cereal crop in Sub-Saharan Africa including Ethiopia. The productivity and production of the crop are not increased as expected due to many limitations in the generation of demand-driven technologies and innovation upscaling in integrated and impact-oriented approaches to sorghum production. The study was focused on sorghum production systems and factors affecting sorghum production for sorghum producers. For this study both purposive and random sampling techniques were applied to select 123 households. OLS regression was used to analyze factors affecting sorghum productivities. In the study areas, the majority of the farmers used the local sorghum variety. Only 17.89% of sample households used improved sorghum varieties including lalo, chemeda, and gemedi varieties. The technology attributes improved sorghum varieties were better performance than the local variety. The regression model revealed that variables including sex, age, education, improved variety, soil slope and fertility, TLU, and extension services affected sorghum productivity positively and significantly at 10%, 5%, and 1% significance levels. Respective experts (BoANR, research centers, NGOs, and Universities) should be advised and support sorghum producers to enhance sorghum productivity.

Published: June 2023

Small-scale commercial farming firms play a critical role in achieving the objectives of the African Union’s Agenda 2063, and the United Nations Sustainable Development Goals (SDGs) in the rural economies of Sub-Saharan Africa. South Africa has a sizeable number of households engaged in small-scale agriculture to supply rural market demand. Small scale commercial agriculture has become a key source of revenue, employment, and food security for communities in rural areas. As such, the South African government has been assisting small-scale farmers financially via the Micro-Agriculture Finance Institutions of South Africa and the Department of Agriculture, Forestry, and Fisheries. This support aims to alleviate poverty, create jobs, and improve food security by promoting small-scale commercial farming, primarily in rural areas. Despite this assistance, there is no clear strategy for achieving significant and evidence-based development. This study outlines a four-step intervention strategy for promoting small-scale commercial farming as a strategy for rural economic development in South Africa.

The seeds of Guibourtia coleosperma serve as potential source of nutritious food for rural communities in northern Botswana though underutilized. The objective of this study was to determine the proximate and mineral composition of G. coleosperma seeds collected from northern Botswana. Seed samples were collected from Shakawe and Kasane areas in northern Botswana. The proximate composition and mineral contents of the seed were determined following standard procedures. The data were analyzed using T-test. Seeds collected from Shakawe had average moisture (%), crude fat (%), crude fiber (%), crude protein (%), ash (%), total carbohydrate (%) and energy (kcal/100g) contents of 8.48 ± 0.29, 9.24 ± 0.31, 4.72 ± 0.60, 15.34 ± 0.48, 2.40 ± 0.02, 59.81 ± 1.00 and 383.80 ± 4.81, respectively. The corresponding values for seeds collected from Kasane were 9.00 ± 0.10, 10.17 ± 0.37, 7.13 ± 0.21, 16.44 ± 0.43, 2.45 ± 0.02, 54.80 ± 0.58 and 376.50 ± 2.22, respectively. Seeds collected from Kasane had significantly higher (p< 0.05) crude fat, crude fiber, crude protein and ash contents than seeds collected from Shakawe. However, the total carbohydrates content of seeds collected from Shakawe was significantly higher (p< 0.05) than those collected from Kasane. No significant differences (p> 0.05) were observed for moisture and energy contents between the seed samples collected from the two locations. The predominate proximate component in the seeds was total carbohydrate followed by crude protein and, therefore, the seeds can serve as good sources of energy and protein. The average zinc, iron, magnesium, potassium, calcium, sodium (mg/100 g) and phosphorus (mg/g) contents of seeds collected from Shakawe were 2.96 ± 0.53, 2.40 ± 0.27, 116.80 ± 2.82, 468.69 ± 19.28, 316.70 ± 21.15, 1.21 ± 0.67 and 1.35 ± 0.04, respectively. The corresponding values for False Mopane seeds collected from Kasane were 2.53 ± 0.31, 3.34 ± 0.18, 173.65 ± 5.83, 460.86 ± 10.53, 367.59 ± 15.37, 3.51 ± 0.44 and 1.45 ± 0.12, respectively. The values for iron, magnesium, calcium and sodium were significantly higher (p< 0.05) for seeds collected from Kasane than those collected from Shakawe. However, no significant differences (p> 0.05) were observed between the seed samples collected from the two locations for zinc, potassium and phosphorus. Quantitatively, the predominant mineral observed in seed was potassium followed by calcium. The seeds could serve as good source of magnesium, iron, zinc, calcium and potassium since they contribute higher proportions of the recommended daily intake of these minerals. The results showed that location has a significant effect both on the proximate composition and mineral contents of False Mopane seeds.

The holometabolous insects go through a complete metamorphosis that includes four life stages: egg, larva, pupa, and imago (adult). Chironomus riparius is a suggested model organism by the Organization for Economic Cooperation and Development (OECD) that is used in acute and chronic tests of chemicals. Tissue morphology of healthy non-biting midge larval stage was already described but the faith of the midgut digestive cells and tissue organization during the metamorphosis is unknown. We here described histological alterations of the midgut during ecdysis to distinguish them from the ones caused by toxins’ negative effects. The present study showed differences in tissue architecture of the midgut in the larval, prepupal, and pupal stages of development of C. riparius. During ecdysis, larval digestive cells detached from the midgut epithelium and moved to the lumen. In the pupa, the larval midgut layer was replaced with an adult midgut that had considerably reduced width. These changes in the midgut tissue morphology and organization probably follow changes in the environment and feeding behavior of C. riparius at different stages of development.

Elements content in plants varies considerably, which is a consequence of various factors, such as plant species, vegetative stage, pedological characteristics of the soil and environmental conditions. The subject of this work is an investigation of the elemental composition of Xanthium italicum ripe and unripe seed collected in Temska using ICP OES. Out of the analyzed macroelements, potassium is the one with the highest concentration, and its content significantly differs in the ripe and unripe seeds. Iron showed five times higher concentration in unripe (27.7 µg/g) compared to ripe (6.2 µg/g) seed. The content of Ba, Cr, Cu, Mn, Pb, and Zn also differ in the ripe and unripe stages of the analyzed seed, which indices that elemental composition is affected by the vegetative stage. Lead and arsenic content are higher than permissible limits, which might affect honey production in this region.

Müdahalenin tanımı veya meşru müdahalenin kapsamıyla ilgili uluslararası hukukta görüş birliği mevcut değildir. Müdahale tanımı oldukça geniştir ve Birleşmiş Milletler (BM) uluslararası hukukla ilgili bilimsel çalışmalarda kapsamlı tartışmaların konusu olmuştur. Ukrayna, Avrupa Birliği (AB), Rusya ve Türkiye’nin Karadeniz Bölgesi arasında stratejik açıdan oldukça önemli bir alanda yer almaktadır. AB ve NATO’nun doğuya doğru genişleme stratejisi sonucu Ukrayna’nın AB ve NATO’ya katılma arzusu Rusya için gerilime yol açan bir unsur olmuştur. Ukrayna devlet başkanı Yanukoviç’in 2013 yılında AB ile Ortaklık görüşmelerine katılmayacağını bildirmesi üzerine Kiev'de Bağımsızlık Meydanında başlayan gösteriler iç krize yol açmıştır. Rusya’nın Kırım’a müdahale etmesiyle bu iç kriz uluslararası bir boyuta ulaşmıştır. Bu bağlamda Ukrayna krizi, Rusya’nın uluslararası topluma ve uluslararası hukuka Soğuk Savaş sonrası çevresinde meydana gelebilecek değişikliklere yeniden meydan okuyacağını göstermiştir. Buradan hareketle çalışmada amaçlanan Rusya’nın Kırım’a müdahalesinin gerçekleşmesine yol açan unsurları incelemektir. Ayrıca, müdahalelerin etkinliğini, uluslararası hukuka uygunluğunu AB-NATO etkisini de göz önünde bulundurarak araştırmaktır. Rusya, Kırım’a müdahale etmesiyle Kırım’ın bağımsızlık referandumu sonrası Rusya’ya bağlanma gerekçelerini uluslararası toplum karşısında haklı çıkarmak için argümanlar sağlasa da mevcut uluslararası hukuk sistemi içerisinde etkin bir çözüm bulunmaması Rusya’nın müdahalesine zemin hazırlamıştır.

The effect of aluminum oxide nanoparticles (Al2O3) on the stability and conductivity of BLM (the bilayer lipid membrane) in solution was studied.  It has been shown that Al2O3 nanoparticles increase the stability of BLM in an electric field, and BLM becomes more stable with increasing their concentration. The experimental data are analyzed in terms of the well-known theory of BLM stability, which is based on the concept of spontaneous formation of microscopic pores on the BLM, the development of which leads to the loss of BLM stability. It is shown that aluminum oxide nanoparticles increase the value of the coefficient of linear tension of the pore edge, and with an increase in the concentration of nanoparticles, the linear tension also increases. It has been shown that the presence of nanoparticles in the solution leads to a decrease in BLM conductivity.
