Oxide Based Dilute Magnetic Semiconductor- A Brief Review
Authors: Mandal Jayanta
Published: March 2022

Dilute magnetic semiconductors (DMS) play an important role in interdisciplinary materials science. Out of this oxygen based DMS this system has been the subject of intense research for Enhancement of magnetic property as well as the Curie temperature. In this system the charge and spin degrees of freedom are accommodated into single matter and their interplay is expected to explore novel physics and new devices. Rare earth oxides have become a interesting field of study for their interesting properties as well as their versatile applications in different fields. Recently the various physical properties, viz., optical (absorption spectra, IR spectra, Raman spectra), magnetic, thermal and hyperfine properties of rare earth oxides have been reported. The various 3d transition metal ion (e.g., Fe, Ni, Co etc) which has also high value of magnetic moment, has been doped in different rare earth oxides, in recent years and it is reported that there is an enhancement in the magnetization. Doping of 3-d metal ion in different rare earth oxide and other semiconducting oxide system can be interesting for the enhancement of magnetization. From the viewpoint of DMS, there may be strong ferromagnetic exchange coupling between localized spins due to carrier induced ferromagnetism and double exchange interaction when localized spin is introduced in the oxide semiconductor.

Metode yang digunakan adalah metode deskriptif analitis dengan pendekatan kualitatif. Deskripsi analitis digunakan untuk menggambarkan keadaan masyarakat yang diteliti. Pendekatan kualitatif menekankan pada data kualitatif. Hasil penelitian menunjukkan bahwa orang Melayu jauh lebih banyak daripada pendatang, tetapi mereka belum memenuhi syarat untuk mendominasi budaya lain. Mereka juga tidak unggul dalam bidang ekonomi. Hal ini terlihat ketika perekonomian umumnya didominasi oleh etnis pendatang seperti Madura, Padang, dan Tionghoa. Hubungan sosial bidang kekerabatan fokus pada pernikahan dalam satu suku. terutama dalam memilih pasangan masih menginginkan pasangan dari sukunya, namun perkawinan antar suku sering terjadi. Hubungan sosial dalam bidang agama tampak sangat toleran antarpemeluk agama yang berbeda. Hubungan sosial dalam kehidupan masyarakat antarkelompok etnis berjalan cukup harmonis, yang berbeda berusaha untuk hidup berdampingan, mempromosikan dan menjaga keharmonisan, terlepas dari asal etnis atau budaya. Mereka cocok dengan masyarakat tempat mereka tinggal.

The method used is descriptive analytical qualitative method with a qualitative approach. Analytical descriptions are used to describe the state of the community being studied as it is. The qualitative approach emphasizes research methods that use qualitative data. The results show that there are far more Malays than immigrants, but they are not yet qualified to dominate other cultures. They also do not excel in the economic field. This can be seen when the economy is generally dominated by ethnic immigrants such as Madurese, Padang, and Chinese. Social relations in the field of kinship, especially in choosing a partner, still want a partner from their tribe, but inter-tribal marriages often occur. The religious factor is still being considered. Social relations in the field of religion seem very tolerant between adherents of different religions. Social relations in peoples lives between different ethnic groups seek to coexist, promote and maintain harmony, regardless of ethnic or cultural origin. In other words, they fit into the society they live in.

Al-Ma’ālāt approach in Islamic Finance: Literature Review as First Step
Authors: Al-Quradaghi Bahnaz , Hassan Aznan , Adewale Abideen Adeyemi
Published: March 2022

The jurisprudence of al-Ma’ālāt is an ancient jurisprudence rooted in Islamic law, and it is concerned with analyzing and taking into consideration the consequences and results people’s actions can generate. The Fiqh was used by the Prophet and Sahaba, and it, thereafter, became so famous during the period of Imam Abu Hanifah, the founder of the Hanafi School of Jurisprudence. Fiqh of al-Ma’alat is a great distinctive feature and one of the important jurisprudential aspects of the Hanafi School. The school makes copious use and reference to the theory and practices of al-Ma’ālāt. Where the Hanafi school uses the term “Ariat i.e., have you pondered if that happened” and then builds the fatwa ruling based on this future event and also on the expected results of this event. History also mentions Al-Shaṭibī’s attempts to draw the attention of the imams of his time to the importance of this jurisprudence through his book Al-Muwafaqāt. But despite all the attempts, the writings on it are still few compared to Maqasid Al shariah, and the writings in it in Islamic economics and finance in the English language are almost non-existent, as there is only one source in English according to the researcher’s knowledge. Unusually however, this important discipline was not given adequate attention especially by later scholars. Despite its significance. The reasons behind that, as the researcher think due to it is not easy to discover and need deep knowledge and interdisciplinary approach which not easy for each imam to discover or can do it. This article is an attempt to restore interest in it by looking at it through several Islamic, economic and administrative aspects, but to start with this jurisprudence to “gain an understanding of the existing research and debates relevant to a particular topic or area of study, and to present that knowledge in the form of a written report. You will also gain insight into how researchers apply the concepts you are learning in your unit to real world problems.

Здійснено спробу аналітичного огляду сучасного українського інформаційного простору щодо питання впливу на людину за допомогою вербальних засобів, які можуть використовуватися під час комунікації з метою отримання бажаного результату. Зокрема увагу зосереджено на такому різноплановому явищі, як сугестія. Це явище нині набуває все більшої актуальності. Загальною метою досліджень у цьому напрямі є систематичний аналіз владного дискурсу крізь призму комунікативних стратегій влади, які допомагають встановити певний порядок у суспільстві. Такий аналіз потрібен для глибшого розуміння державотворчих процесів, набуття уміння розпізнавати маніпулятивні технології задля запобігання небажаним їх проявам та отримання можливості вчасно застосовувати відповідний інструментарій протидії. З’ясовано, що певні мовні висловлювання, які наповнюють український інформаційний простір, можна інтерпретувати як сугестивні. Сугестивні технології зазвичай використовуються для отримання позитивного (потрібного) результату. Зроблено припущення щодо можливості різного трактування сугестивних технологій впливу: або пояснювати їхнє використання отриманням потрібних для розвитку держави процесів, або ж розглядати їх як маніпуляцію та навіювання. У контексті захисту інформаційного простору держави наголошено на важливості та необхідності більше уваги приділяти саме можливим негативним наслідкам такого впливу. Проблема подальшого розвитку нашої держави є комплексним, багатофакторним і складно структурованим завданням, яке потребує інноваційного підходу до формування й реалізації публічної політики за всіма напрямами, галузями й сферами, здатної адекватно реагувати на виклики та забезпечувати виконання вимог, що постають перед Україною в умовах глобалізованого світу.

Findings. The directions of improving the fastening and protection structures, which ensure the stability of reused mine workings, have been determined. In this case, the most lightweight protection structure is proposed, the functions of which are transferred to the collapsed and compacted rocks of the uncontrolled collapse zone. Originality. The basic concept of repeated use of mine workings, taking into account resource-saving technologies, has been formulated and implemented. The stress-strain state of the “mass – support – protection elements” system has been studied, and its rational parameters have been optimized. An example of an optimization solution based on the stated methodology is presented. Practical implications.

Substantiation of mining-technical and environmental safety of underground mining of complex-structure ore deposits
Authors: Lyashenko Vasyl , Andreev Boris , Dudar Tamara
Published: March 2022

Purpose. Substantiation of mining-technical and environmental safety of underground mining of complex-structure ore deposits based on the study of a rock mass stress-strain state (SSS), as well as determining the safe parameters of stopes for specific mining-geological conditions and patterns of rock pressure propagation in various environments. Methods. To assess the improvement of mining-technical and environmental safety of mining operations, the research includes theoretical generalizations with the use of mathematical statistics, physical and mathematical modeling, performing calculations, as well as technical and economic feasibility, laboratory and full-scale experimental studies, industrial tests in mine conditions and on the earth's surface in the zone of blasting influence, based on the standard and new methods. Findings. A functional interrelation between the rock mass SSS value and the number of impulses (destruction sounds) per minute, characterizing its structural (а) and strength (b) properties, is proposed, which is described by a curvilinear dependence of the type y = axb and allows to quickly determine the stable parameters of stopes. Assessment and prediction are made for various forms of rock pressure manifestation, based on the stress concentration coefficient within 0.91 Kv 0.70, taking into account the conditions of the elastic behavior of rocks. The value of = 0.0002-0.0003 is taken as permissible relative deformation, which ensures both mining-technical and environmental safety, as well as the rock mass stability during repeated blasting operations. Originality. A classification of the rock mass SSS has been developed depending on the direction of the maximum stresses relative to the mine working location, the level of the rock mass stress state and the mechanism of rock pressure manifestation (η), as well as the category of rock-bump hazard. In particular, the rock mass with the values in the range oof 0.12 < η ≤0.2; 0.2 < η ≤ 0.3; 0.3 < η ≤ 0.5 and η > 0.5 are classified as non-rock-bump hazardous and belong to III, II, and I hazard categories, respectively. Practical implications. To substantiate the safe parameters of stopes based on the results of multi-year research into underground mining of complex-structure deposits, depending on the rock mass properties, a graphical-analytic method (nomographic charts and calculation formulas) is recommended. These parameters are determined for highly fractured, medium fractured and weakly fractured rock mass with its horizontal outcropping to the surface. Using this method, the Instruction on the Geomechanical Substantiation of the Safe Mining of the Reserves at the Skhidnyi Hirnycho-Zbahachuvalnyi Kombinat, DP (SE VostGOK), Ukraine, has been developed.

Published: March 2022

Purpose.Increasing the load-bearing capacity of metal arch supports used to maintain the mine workings due to strengthening in places with the highest bending moment. Methods. The stress-strain state of the rock mass and support is analyzed using the ANSYS software package. The problem is studied in three variants: a support without strengtheners, a support with one strengthener in the area with the maximum bending moment, and a support with three strengtheners in the areas with the highest bending moments. To determine the bending moments and normal forces in a three-section metal arch support, the finite element method is used for specific and existing conditions, which is followed by the selection of the required standard size of the support. Findings. The conducted research gives reasons to believe that the proposed variant for increasing the load-bearing capacity of the support, made from a special replaceable rolled profile (SCP), can significantly improve the state of mine workings. Obviously, the proposed solution can be applied not only to arch supports, but also to other structures of rolled metal support. Originality. The pattern of changes in the values of internal forces arising in metal arch frame supports, depending on the deformation characteristics, the location of the strengtheners, as well as on the geometric characteristics of the mine working and the ratio of lateral and vertical loads on the support, has been determined. Practical implications. The proposed variant for increasing the load-bearing capacity of the support can be used to sustainably maintain mine workings in difficult mining-geological conditions of the Karaganda Coal Basin mines.

Authors: Akther Sonia , Hassan Md Zakir
Published: March 2022

Preventive measures to combat with Newcastle disease virus (NDV) can be achieved by vaccination programs that are practiced in many countries of the world. Even after vaccination outbreaks of NDV occurred in the flock indicate that vaccination against NDV cannot provide effective immunity that may cause disease in partially vaccinated flock. Hence, the objectives of this study was to development of flock immunity in chicken against Newcastle disease in a local community. In this study a vaccination programme for the native flock in a locality (Dhamrai, Savar, Dhaka, Bangladesh) was conducted and effectiveness of the Ranikhet disease vaccine (RDV) was identified with detection of antibody titers that may protect the native flocks against the disease but mortality or the infection was present. The study showed that after routine vaccination with BCRDV (Baby Chicks Ranikhet Disease Vaccine) and RDV (Ranikhet Disease Vaccine) vaccine the native chicken showed high antibody titre in native chicken. Overall herd immunity of native chickens can be achieved if the maximum (>80%) chicken obtains high antibody titers (log2 haemagglutination inhibition titer ≥3) after vaccinations. So, it can be concluded that successful vaccinations programme is the key point to control NDV with higher herd health immunity.

Published: March 2022

Soybean mosaic virus (SMV) is the major constraints for soybean cultivation in many parts of the country. Experiments were carried out to study the seed transmission of SMV and to identify the resistant sources through screening of 30 promising soybean genotypes obtained from different sources under natural infections conditions in between 2000 and 2001. Indirect-ELISA was performed against TRSV, TMV, CPMV, CMV, BBSV, BBTMV and SMV in leaf materials, both from healthy and diseased plant materials and the results showed that the seeds and the plants in the field were free from those 6 viruses. The highest seed transmission was found in Gaurab (15.07%) followed by G-2120 and the lowest (1.5%) seed transmission was found in TG-893 followed by BS-32, CM and AGS-129. Seed mottling was found related to seed transmission. No disease incidence was found in AGS-129 but there were seed mottling (1.25%). On the other hand, genotype AGS- 160 was free from mottled seeds but produced infected seedlings. Mosaic symptom became apparent 15 days after sowing (DAS), highest at 60 DAS and disappear after 90 DAS. Seeds from seed lot containing up to 20% mottled symptom could not hamper production. Screening of 30 soybean genotypes based on the natural infections revealed that AGS-129 was identified as resistant and grading 1, 10 were identified as moderately resistant (MR) considered as grading 3 and the remaining genotypes were susceptible (S) and moderately susceptible (MS) considered as grading 7 and 5, respectively. The 10 genotypes viz. CM, BS-32, ACAGS-154, G-2261, AGS-129, Durga, Williams, AGS-160, EC-1178 and PR-164 could be used for further study to locate resistant genes against soybean mosaic virus and varietal improvement in breeding purpose.

D-Optimal Designs for dose Finding in Phase I Clinical Trials
Authors: Sujan Hasan Mahmud , Alam M Iftakhar
Published: March 2022

Determining the maximum tolerated dose (MTD) is the main challenge of phase I clinical trials. There are many methods in the literature to determine the MTD. The D-optimal design can also be used to find the MTD. The D-optimal design depends on the Fisher information matrix (FIM), and it minimizes the generalized variance of the parameter estimates. However, the D-optimal design is yet to receive much attention from clinicians. Since a dose-response model is usually non-linear, the FIM depends on the unknown model parameters. To optimize the FIM through the D-criterion, values need to be assumed for the model parameters. This paper focuses on investigating four different D-optimal designs depending on parameter values: design based on posterior Bayes estimators, design based on maximum likelihood estimators, sequential Bayesian design and two-stage Bayesian design. Six plausible dose-response scenarios and a real scenario are investigated through a simulation study. Except for the D-optimal design that utilizes maximum likelihood estimates in FIM optimization, all other D-optimal designs are found very competitive for the correct MTD recommendation. The D-optimal designs are also compared with an A optimal design. The performance of A-optimal design is not attractive as these designs. Because of its numerical simplicity compared to the others, the posterior-based D-optimal design is recommended for dose-finding in phase I clinical trials.

Published: March 2022

The Ti-6Al-4V alloy has been widely used for structural materials due to high specific strength property, however it is difficult to cast because of high reactivity at high temperature. In this study casting characteristics and post-casting heat treatment were studied in the cast Ti alloy. The cast alloy was prepared using high-frequency induction heating and horizontal vacuum centrifugal casting to reduce reaction with crucible and mold by minimizing overheating of the molten metal and casting fast. In the thin casting with a thickness of 2 mm, α’ martensite was observed, and in the casting with a thickness of 4~8 mm, α+β Widmanstätten was observed. As the thickness of the casting increased, the grain size, α-lath width, and α-case thickness increased. Accordingly, as the thickness of the casting increased, the hardness of the matrix decreased and the hardness of the surface increased. In addition, when the casting was heat treated below the β-phase transformation temperature, the α-lath width increased, and when quenched after heat treatment in the β-phase transformation temperature region, an α’ martensite was formed. On the other hand, when the casting was heat treated in the atmosphere, it was confirmed that the elongation was very low because hydrogen and oxygen in the atmosphere were induced. In addition it was confirmed that casting defects can be removed through HIP.

Does High Vitamin B12 Levels Cause Proteinuria?
Authors: Bayraktar Mustafa , Kösedag Murat
Published: March 2022

Aim: Cubilin receptors, which are responsible for the absorption of vitamin B12 from the intestine, are also found in the kidney and regulate protein reuptake from urine. We claimed that vitamin B12 deficiency may lead to less proteinuria as a result of increased Cubilin receptors, or higher vitamin B12 levels may cause proteinuria by down regulating the receptors. To support this hypothesis, the relationship between vitamin B12 and urine protein levels was investigated.

Methods: The last two-year hospital records of patients between the ages of 18-65 were retrospectively scanned. Patients who were tested for the vitamin B12, plasma creatinine, and urine protein analyses and whose eGFR value was calculated as >60mL/min were included. Patients diagnosed with diseases that may cause proteinuria such as diabetes, malignancies, or kidney diseases were excluded. Vitamin B12 level 1000 pg/ml as hypervitaminosis.

Results: Of the 31,776 patients who met the criteria, vitamin B12 deficiency was found to be 38.6% in men; 33.1% in women, and 35% in total. Rates of hypervitaminosis B12 were 1.4% in both men and women, and overall. Urinary protein was observed in 13% of all patients. A statistical significance was found between vitamin B12 levels and proteinuria. In post-hoc analysis, this statistical difference was detected between the hypervitaminosis group and the other levels.

Conclusion: Vitamin B12 hypervitaminosis was found to be statistically associated with proteinuria, indicating that caution should be exercised in vitamin B12 treatment.

Keywords: vitamin B12, hypervitaminosis, proteinuria

Published: March 2022

Exposure of dairy cows to heat stress negatively affects welfare and performance during all phases of the lactation cycle. Detrimental effects include decreased milk and reproductive performance, reduced immune status and health, and altered natural behaviors. While we understand how mature cows respond to heat stress, the effects of late gestation heat stress on pregnant heifers is still unknown. Automated monitoring devices were used to document the behavioral activity of heifers during the pre- (final 60 d of gestation) and postpartum (first 60 d of lactation) periods. Twenty-five pregnant Holstein heifers were housed in a free-stall barn and enrolled to heat stress (HT; shade; n = 13) or cooling (CL; shade, soakers and fans; n = 12) treatments during the last 60 days of gestation. All animals were provided active cooling postpartum. Upon enrollment, heifers were fitted with a leg tag, which measured daily lying time, number of steps, and standing bouts, and a neck tag that measured eating and rumination times. Rectal temperatures (RT) and respiration rates (RR) were measured thrice weekly during the prepartum period. Relative to CL, HT heifers had elevated RT (38.8 vs. 38.7 ± 0.04°C) and RR (59.6 vs. 44.4 ± 1.9 breaths/min) during the prepartum period. Heat-stressed heifers tended to spend more time eating (224 vs. 183 min/d) and less time ruminating (465 vs. 518 min/d) during the prepartum period compared to CL, but dry matter intake did not differ. During the postpartum period, HT heifers spent more time eating (209 vs. 180 min/d) during weeks 1–4 of lactation, but rumination time was similar. Lying time was reduced by 59 and 88 min per day during weeks −7 and −6 prepartum and 84 and 50 min per day during weeks 2 and 3 postpartum in HT heifers, relative to CL. The number of steps was greater for HT during the postpartum period, from weeks 2 to 9 (3019 vs. 2681 steps/d). Eating frequency was similar during pre- and postpartum periods, however, based on semi quantitative visualization of the smarttag reports, HT consumed larger meals at night during the pre- and postpartum periods compared with CL heifers. In summary, late-gestation exposure to heat stress affects the daily time budget of first lactation heifers during both the pre- and postpartum periods. Current insights of heat stress effects on behavioral responses of dairy heifers may contribute to the development of more effective management strategies to mitigate heat load.
The Effects of Geometric Features of Intraluminal Thrombus on the Vessel Wall Oxygen Deprivation
Authors: Carbino Burton , Guy Alexander , Durka Michael , Zakerzadeh Rana
Published: March 2022

The objective of this paper is to analyze the association of intraluminal thrombus (ILT) presence and morphology with oxygen transport in abdominal aortic aneurysms (AAA) and local hypoxia. The biomechanical role of the ILT layer in the evolution of the aneurysm is still not fully understood. ILT has been shown to create an inflammatory environment by reducing oxygen flux to the arterial wall and therefore decreasing its strength. It has been also hypothesized that the geometry of the ILT may further affect AAA rupture. However, no previous research has attempted to explore the effect of morphological features of ILT on oxygen distributions within the AAA, in a systematic manner. In this study, we perform a comprehensive analysis to investigate how physiologically meaningful variations in ILT geometric characteristics affect oxygen transport within an AAA. We simulate twenty-seven AAA models with variable ILT dimensions and investigate the extent to which ILT attenuates oxygen concentration in the arterial wall. Geometric variations studied include ILT thickness and ILT length, as well as the bulge diameter of the aneurysm which is related to ILT curvature. Computer simulations of coupled fluid flow-mass transport between arterial wall, ILT, and blood are solved and spatial variations of oxygen concentrations within the ILT and wall are obtained. The comparison of the results for all twenty-seven simulations supports the hypothesis that the presence of ILT in AAA correlates to significantly impaired oxygen transport to the aneurysmal wall. Mainly, we observed that ILT thickness and length are the parameters that influence decreased oxygen flow and concentration values the most, and thick thrombi exacerbate hypoxic conditions in the arterial wall, which may contribute to increased tissue degradation. Conversely, we observed that the arterial wall oxygen concentration is nearly independent of the AAA bulge diameter. This confirms that consideration of ILT size and anatomy is crucial in the analysis of AAA development.
