Authors: Muhammad Habibullah Nur Ihsan  , Muhammad Silmy Amjad  , Bima Andhika Fernanda  , Mohamad Bastomi
Published: April 2023

Investment is the placement of some funds at this time with the hope of obtaining future profits. The fundamental thing in the investment decision process is to understand the relationship between the expected rate of return and the risk of an investment. The uncertainty of risk makes investors take a strategy to form a portfolio. Portfolio is a combination or combination or a set of assets, both in the form of real assets and financial assets owned by investors. Investors always want to maximise the expected return with a certain level of risk that they are willing to bear, or look for a portfolio that offers the lowest risk with a certain level of return in forming a portfolio. The characteristics of such a portfolio are referred to as an efficient portfolio. An investor needs to understand the meaning of investment, investment objectives, investment risk, and investment return. This study aims to introduce the Markowitz model in analysing the expected rate of return and its risks. The research method used in writing this article uses qualitative research with literature studies. From the discussion, it can be concluded that an investment portfolio can consist of several classes of the same asset or the same asset but consists of several different names. Investors can find out what stocks can be included in the optimal portfolio and the proportion of funds for each of these stocks formed by the Markowitz model

Structural, dynamical, thermodynamic properties of CdYF3 perovskite
Authors: J. Liu  , R. Yang
Published: April 2023

The thermoelectric and thermodynamic characteristics of CdYF3 were examined for the first time using the density functional theory (DFT) framework within the generalized gradient approximation (GGA). The stability of the material is justified by calculating the optimization and phonon calculation. We employed diverse approximations like LDA, WC- GGA, PBE-GGA, and GGA-PBE-sol approximation to analyse the variation in the band gap while these approximations reveal an underestimate of the bandgap. Therefore we, employed the GGA+Trans-Blaha modified Becke–Johnson (TB-mBJ) approach to get the accurate bandgap with 2.305 eV value from (M-X) of the CdYF3 compound. Additionally, we computed transport properties against the temperature, Chemical potential, and charge carrier concentrations of the CdYF3 compound. At the optimum charge carriers, the calculated power factor suggests that p-type CdYF3 has a power factor. We also calculated the thermodynamics properties to evaluate the heat capacity at constant volume and pressure, enthalpy, etc. As a result, significant ZT in CdYF3 was achieved at higher values at room temperature to use in the thermal devices

Authors: L. Li  , S. Naher
Published: April 2023

The present manuscript reports structural stability, half-metallic behavior, thermophysical and thermoelectric properties of Co2MoAl and Co2TcAl full Heusler compounds using first-principle calculations. The full-potential linearized augmented plane wave method within the framework of density functional theory is implemented and WIEN2k code is incorporated in the stable Fm- 3m phase to attain the desired results. The L21 phase is found as the most stable phase for both compounds. The optimized equilibrium lattice parameters in the stable phase are 5.89Å, 5.86Å for Co2MoAl and Co2TcAl respectively. The electronic band structure study proves that both compounds Co2MoAl and Co2TcAl have indirect band gaps of 0.74eV and 0.85eV respectively in majority spin alignment. The half-metallic performance of the present set of compounds is explained by the spin-resolved density of states. The Fermi level at the Brillouin zone point approves the metallic as well as semiconducting behavior. To elucidate the thermodynamical stability of these materials against pressure and temperature by implementing the quasi-harmonic approximation of various parameters like Debye temperature, Gruneisen parameters and specific heat are studied successfully. To know the thermoelectric response, Seebeck coefficient and electrical conductivity are computed using the BoltzTrap code. The thermodynamic profile delivers that the present set of compounds possesses no anomalies with respect to the phase transition or instabilities. The computational study insights that the compounds can be synthesized experimentally and find a route towards spintronic and thermoelectric applicability.

Published: April 2023

The compositional dependence of the polarities, elastic constants, elastic moduli, Poisson's ratio, and linear compressibility has been computed for zinc blende AlxIn1-xPySbzAs1-y-z alloys with composition y ranging from 0 to 1. Also, the compositional influence of the bond-stretching force constant, bond-bending force constant, internal strain parameter, Cauchy ratio, effective charge, the Born ratio, anisotropy factor, and sound velocity has been determined. The experimental data and the studied properties for the novel studied alloy lattice matched to the InP substrate show a good level of agreement. The empirical pseudo-potential approach and the virtual crystal approximation have been employed in this work. The obtained results are predicted to help understand the elastic characteristics of AlxIn1-xPySbzAs1-y-z and for applications in optoelectronics.

The concept of transparency is a fundamental principle in administrative management that allows citizens to access any type of information or document issued by public entities as part of their functions. This article aims to describe the transparency of public information in the era of the metaverse and artificial intelligence. The guarantee of this right implies, first, the commitment to provide public information openly and freely in all terms, without any kind of restriction and with appropriate truthfulness; second, responding to citizens in a truthful, timely and efficient manner with the aim of covering their needs and interests; and third, producing and/or capturing public information in order to achieve citizen satisfaction. The transparency of public information remains essential in the era of the metaverse and AI. While these new technological developments present challenges, they also offer opportunities to develop innovative transparency practices that can improve democracy and life in society. The era of the metaverse and AI presents significant challenges for the transparency of public information. The limitations to verify information in the metaverse and the opacity of AI pose important barriers to ensure transparency and accountability. It is necessary to develop specific transparency policies and practices for the metaverse and AI, and to promote public education on these topics. It is essential to work on solutions to ensure transparency and responsibility in the digital era.

Published: April 2023

The aim of this study was to evaluate the effect of methanol leaf extract of Terminalia catappa. Freshly harvested leaves of T. catappa were washed, dried and ground into fine powder. The powdered plant sample was processed into extract. Twenty five adult male wistar rats were divided into five groups of five rats. Group I: was the normal control fed only with rat chow and water, Groups II-V were administered with 100, 200, 400 and 600 mg/kg of methanol leaf extract of Terminalia catappa (MLETC). Treatment lasted for 28 days, after which animals were sacrificed and blood sample collected analysed using standard procedures. The result obtained showed that oral administration of extract significantly (P<0.05) increased the activity of liver enzyme in a dose dependent manner. This may or may not necessarily imply that the extract is hepatotoxic as certain compounds can induce the said enzymes and may not mean that the liver is damaged.

Authors: Zahur-Uz-Zaman Md. , Anjum Nishat , Dey Sayket , Zakir Hossain Mohammad
Published: April 2023

The most vitally significant ingredient that all life on earth needs in order to survive is water. The global rate of wastewater discharge is rising quickly in tandem with population growth. As a result, wastewater treatment is a viable option to take into account for increased water demands. This investigation's primary objectives are to examine the contaminants found in wastewater and assess the efficiency of filtering collected wastewater using a mixture of coconut fibers, rice husks, sand, and stone chips. The untreated wastewater was gathered from KUET's six separate residence halls in Bangladesh. Inflow water and outflow water from filter media were used to measure a number of wastewater quality characteristics for the samples that were collected. Physical and chemical tests such as those for suspended particles, pH, turbidity, total coliform, and fecal coliform are among the factors examined in this study. Both coconut fiber and rice husk have been found to be useful as filter medium for the removal of contaminants present in wastewater. Because coconut fiber has a large number of micro pores with a standard surface area, it eliminates fungus and rice husk functions as an adsorbent for pollutants in wastewater.

Authors: CHUKWUMATI JA  , IKIRIKO M
Published: April 2023

Study was conducted at the screen house of department of crop and soil science, University of Port Harcourt to investigate the influence of two waste dumpsites on soil chemical properties and performance of okra in Obio/Akpor. A composite soil samples was randomly collected at two depths (0-15 and 15-30) cm from two dumpsites from Choba and Rumunduru at a distance of (0-1) and 100 meters (control) away from the dumpsites. The soil was placed on 10kg perforated bucket; three seeds of okra were planted per bucket and later thinned to two after germination. It was left for eight weeks. The experiment was on complete randomized design. Results showed significant (P<0.05) increase in soil chemical properties (%TOC, available P, TN, Ca, Mg and K) in impacted zone (0-1)meter over control (100) meter away in the two dumpsites. The soil chemical properties were significantly higher in Rumunduru dumpsite than Choba. There was no significant (P>0.05) difference in soil depths in the two locations, however, the concentration of soil chemical properties slightly decrease with increase in soil depth. There was a decrease in the concentration of heavy metals (Ni, Pb , Fe and Zn) along the main dumpsites away from the control in the two locations studied. Significant increase was observed in concentration of heavy metals in Rumunduru dumpsite over that of Choba. Concentration of the four metals decreased with increase in soil depth. All the metals were above the permissible limits with the exception of nickel. There was a significant (P<0.05) reduction in plant height on the impacted zone (0-1) m in distance over the reference point (control) in the two dumpsites. Significant difference was not noticed between the two soil depths, though the height was slightly higher at 0-15 depth than 15-30cm. Waste dumpsites affected negatively the plant performance especially at the impacted zone as there was retardation of growth and an increase in concentration of heavy metals.

Published: April 2023

The study aims to treat polluted water before it is released into the environment or used in reinjected oil wells. The test runs were done by an electrocoagulation unit that was collected and introduced in the lab. The current was utilized as a part of the unit with various densities to test the turbidity-expelling effectiveness. The exploratory outcomes revealed that the grouping of oil was diminished to (10.7, 11.2, 11.7, 12.3) mg/l when distinctive current densities of (0.00253, 0.00633, 0.01266, 0.0253) A/cm2 were utilized separately. We conclude from this research that the best current in terms of stagnation removal is 0.0126 A/cm2 and the minimum distance between the electrodes, and in terms of oil removal, the highest removal at the current is 0.0253 A/cm2.

Authors: Jamaladdeen Kabir , Bashir Gide Muhammad  , Ahmed Rufai Usman
Published: April 2023

The amount of radiation dose received by patient undergoing Head computed tomography examination in General Amadi rimi orthopedics and specialist hospital, Katsina has been estimated. Computed tomography dose output was used to determine the effective dose and organ dose of non-contrast to the head region of 30 patients. The tube potential ranged from 127 kVp to 130 kVp, while the mAs ranged from 130 mAs to 140. The aims of this study are, first, to assess the mean effective doses received by patients undergoing Head CT examinations and compare them with other studies. Mean values of CTDIvol. was (43.1mGy), the mean DLP values was (1206 mGy.cm), the mean effective dose (HEDLP) value was (2.4 mSv). The result was compared with the European Union reference dose level and other published factor. HEDLP was slightly higher than the values reported from the literature for the united nation and European union report by 0.4 factor. It was concluded that patient organ doses could be substantially minimized, optimized and justified. The high variation in the doses in this study may be due to differences in imaging protocols such as large range of mAs and scan length and also algorithms of the scanner.

The relevance of the research is associated with the need to study changes in the lungs caused by rapidly growing strains of nontuberculous mycobacteria (NTM). Objective: to analyze results obtained by the complex study of the lungs for evaluation of the frequency and nature of terminal bronchiole lesions in patients with nontuberculous mycobacterial (NTM)infection caused by rapidly growing strains. Materials and methods. We carried out clinical, radiological, morphological, and spirometric studies of the lungs of 35 patients with rapidly growing NTM strains isolated by real-time PCR. All the patients underwent multislice CT (MSCT) of the chest using the Somatom Emotion 16 scanner (Siemens, Germany) based on the high resolution computed tomography (HRCT) algorithm with 0.8 mm slice thickness and 1.5 mm slice increment. Lung ventilation was studied using the standard spirometry. Morphological studies were performed using resection samples from 11 patients with pulmonary TB comorbidity and 7 patients with only TB (the comparison group). Results. Rapidly growing strains of NTM cause exudative lymphocytic bronchiolitis, cell infiltration of the peribronchial tissue, which is not typical for TB infection. Later, lymphocytic bronchiolitis of terminal bronchioles develops into chronic constrictive bronchiolitis accompanied by the development of bronchiolectasis, atelectasis, and emphysema confirmed by HRCT results. They show prevailing bronchogenic lesions of small airways, accompanied by obstructive-type pulmonary ventilation disorders in 80% of cases (FEV1 is more than 70% of the predicted values). The results of the complex study should be considered in diagnosis and treatment of patients with NTM infection of the lungs.

Objective: to investigate T cell immune response to SARS-CoV-2 in children and adolescents with pulmonary TB with history of the novel coronavirus disease and/or exposure to the novel coronavirus infection. Materials and methods. We chose patients aged 12–17 years with pulmonary TB and different variants of interaction with the novel coronavirus infection. We studied 15 blood samples using the TigraTest® SARS-CoV-2 assay (after 5 months of the disease or exposure to COVID-19), and the qualitative determination of IgG antibodies (after 2, 4, and 6 months). We performed complex clinical, microbiological, and radiological studies to assess the dynamics of TB process. The course and severity of COVID-19 disease was assessed according to the methodological recommendations of the Russian Ministry of Health (as of 17.11.2021). Results. Positive results of TigraTest® SARS-CoV-2 were obtained in 9 out of 11 patients (after the disease or exposure to COVID-19), negative results were obtained in 2 patients without IgG antibodies to SARS-CoV-2. The patients had mild course of COVID-19; exacerbations were not observed. In 4 patients (without history of COVID-19 disease, exposure was not reliably established) negative T cell and humoral immune responses were observed. Conclusion. It is important to investigate T cell immune response to SARS-CoV-2 due to rapid disappearance of IgG antibodies (by the 4th month after the disease). The absence of IgG antibodies impedes the prognosis of nosocomial infection in a hospital.

Materials and methods: aretrospective comparative study enrolled 141 patients aged 2–17 years with different forms of pulmonary TB. Upon completion of the main chemotherapy course consisting of the intensive and continuation phases, the patients were divided into two groups: group 1 – patients with treatment failure, group 2 – patients with treatment success. We compared the patients’ gender and age, social status of the families, the presence of medical or biological risk factors (the absence of anti-TB vaccination, concomitant chronic diseases, acute infectious diseases during the treatment, TB  process at detection, drug resistance patterns in the patients and infection sources, the time of drug resistance development, the information about chemotherapy regimens and treatment administration, the occurrence and duration of treatment interruptions) in the groups. The obtained data were processed using binary logistic regression carried out by the SPSS 21.0 software. Results: we built a mathematical statistical model of the individual risk for treatment failure among children and adolescents with pulmonary TB. Conclusion: the major risk factors for treatment failure among children andadolescents with pulmonary TB were associated with inadequate chemotherapy: ignorance of drug resistance patterns on the initial treatment phase, defective use of chemotherapy potentials, wrong choice of treatment administration form. Late detection of TB (lung destruction, advanced TB process) was a more frequent factor in group 2 than group 1 but did not significantly influence treatment outcome.

Pulmonary mycobacteriosis has become a new global health challenge. The development of severe lung pathology, which requires long-term complex therapy with broad-spectrum antibiotics, can only be caused by some of the currently described nontuberculous mycobacteria. The treatment for mycobacteriosis requires long-term administration of combined antibacterial drugs, may cause adverse drug reactions, or fail. A clinical case of progressive pulmonary mycobacteriosis in a 53-year-old female patient is described in the article.

Published: April 2023

Öngörülemezlik inançları, kişinin kendisini, diğer insanları ve dünyayı tutarsız olarak değerlendirmesiyle ilişkili bir kavramdır. Bağlanma kuramı, öğrenilmiş çaresizlik kuramı, yaşam öyküsü kuramı ve duygunun değerlendirme kuramı temelinde ortaya çıkmıştır. Yapılan araştırmalar öngörülemezlik inançlarının aile öngörülemezliği, nedensel belirsizlik ve sürekli kaygı gibi olumsuz sonuçlarla ilişkili olduğunu göstermiştir. Bu araştırmanın amacı, öngörülemezlik inançları düzeyini ölçmek için geliştirilen Öngörülemezlik İnançları Ölçeğinin Türkçeye uyarlama, geçerlik ve güvenirlik çalışmalarının yürütülmesidir. Öncelikle çeviri çalışması yapılmış ve veri toplama aşamasına geçilmiştir. Araştırmaya 18-30 yaş aralığındaki (Ortalama = 21.17, Standart Sapma = 2.06), 445’i kadın ve 118’i erkek toplamda 563 kişi katılmıştır. Katılımcılar Demografik Bilgi Formu, Öngörülemezlik İnançları Ölçeği, Geçmişe Dönük Aile Öngörülemezliği Ölçeği ve Kısa Semptom Envanterini tamamlamıştır. Yapılan doğrulayıcı faktör analizi sonucunda orijinal formdaki 3 faktörlü yapı doğrulanmıştır. Ölçeğin iç tutarlılık düzeyini belirlemek için hesaplanan Cronbach Alfa katsayıları .76-.87 arasındadır. Test-tekrar test güvenirlik katsayıları ise .78-.87 arasında değişmektedir. Bu bulgulardan yola çıkarak ölçeğin Türkiye’de kullanım için geçerli ve güvenilir olduğu sonucuna varılmıştır. Böylelikle Türkiye’de yapılacak çalışmalarda kullanılmak üzere önemli bir ölçüm aracı dilimize kazandırılmıştır. Ayrıca, erken dönem kişilerarası ilişkilerin yanı sıra erken dönem çevrenin de yetişkin yaşamındaki psikopatolojilerle olan bağlantısı ortaya konmuştur.

Background: The present study was performed to assess the therapeutic effects of combined intra and extraarticular dextrose prolotherapy on knee osteoarthritis and its comparison with intra- articular triamcinolone injection. Methods: In this study, 50 patients suffering from knee osteoarthritis were allocated into two groups as a double-blind randomized clinical trial. The first group received one session of dextrose prolotherapy as one intra-articular injection of 10cc dextrose 16% and periarticular intradermal injections of dextrose 12% at 4 points around the knee (2.5 cc at each point). The second group underwent therapy with one intra-articular injection of triamcinolone (40 mg). Results: Compared to pretreatment, both interventions caused significant improvement in pain (evaluated by VAS) and WOMAC (all its components) in 1 and 3 months postintervention (all with P-value < 0.005). In the first month, pain reduction was significantly better in corticosteroid group (P-Value 0.002 and 0.048 respectively). In third month post intervention, improvements in VAS and WOMAC components were significantly greater in prolotherapy group. Conclusions: Both methods of corticosteroid and dextrose prolotherapy (combined intra and extraarticular technique) are effective on pain and function of patients with knee osteoarthritis. Compared to corticosteroid, prolotherapy method was associated with less pain reduction in short- term, but its effects were more persistent and in midterm examinations (3 months), it was more effective than corticosteroid.

Published: April 2023

: Urethral cancer is one of the rarest cancers. This study reported four cases treated in our department during the last two years. The patients’ medical histories differed and showed various symptoms and courses of illness. Each patient was treated surgically and received additional treatment. Two patients had pelvic injuries recorded in their medical history. One patient had progressive cancer on the basis of condyloma. The late diagnosis was a significant problem. None of the patients presented distal metastasis at the time of diagnosis, but the local advancement was significant. The courses of disease were aggressive in all patients. This study also reviewed the literature concerning primary male urethral cancer regarding the course of the disease and possible treatment methods.

Discute-se, no presente artigo, como a denominada grande mídia do estado do Espírito Santo divulgou os movimentos de ocupação estudantil, ocorridos no ano de 2016. Definimos como objeto de análise, as reportagens sobre as ocupações escolares veiculadas no ESTV 1ª Edição – noticiário televisivo líder de audiência em seu horário. O nosso objetivo foi levantar e discutir elementos da construção da narrativa em relação às ocupações das escolas capixabas. Em uma segunda camada interpretativa, dado o hiato temporal, comparar com os resultados formativos tendo por base resultados de pesquisas. Para tal, analisamos as referidas reportagens, a partir do conceito de sociedade do espetáculo de Debord (2003), das considerações sobre o showrnalismo de Abex Jr. (2001) e da compreensão sobre a construção das agendas sociais e políticas, baseada no conceito de conflito social, defendido por Santos (2009). Os resultados apontam para as correlações entre os interesses manifestos nas edições das reportagens da época.
