The enriched thermal mechanisms and progressive of nanomaterial has enthused scientists to give devotion to this area in current days. The versatile and synthesizing utilization of such particles embrace energy production, solar systems, heating and cooling monitoring processes, renewable energy systems, cancer treatments, hybrid-powered motors and Nano electronics. Furthermore, in this era of biotechnology and bioengineering, the bio convection of Nano fluids provides for some enthralling applications, such as enzymes, biosensors and biofuels. With such magnetic applications and attentions. A mathematical model is presented for evaluating the electrical conducting Williamson nano fluid with heat and mass transfer over a porous stretched sheet in the existence of bioconvection. The bioconvection of swimming microorganisms, thermal radiation,thermal conductivity and Arrhenius energy are new facets of this investigation. The higher order non-linear governing partial differential equations (PDEs) are solved by applying appropriate similarity variables and resulting couple of ordinary differential equations (ODEs) is produced. The developing set of ODEs is solved numerically by utilizing well known shooting technique with ND solve command in Wolfram MATHEMATICA and compare the result with pvb4c code in MATLAB. The graphs for different physical quantities of interest together with non-dimension velocity, temperature, concentration and density of micro-organisms profiles are discovered for involving parameters like .magnetic parameter, Brownian motion, Rayleigh number, Peclet number, Bioconvective Lewis number, parameter of thermophoresis and buoyancy ratio parameter. The influence of numerous parameters on flow and heat transfer characteristics are debated.

Authors: Alawi Badiaa Ismal , Ali Nadia Abbas 
Published: October 2023

Herein, the PMMA/MWCNT/Ag hybrid composite films are prepared by solvent casting method to be used in an electrical application. The AC conductivity and dielectric characteristics have been investigated at room temperature. The electrical conductivity of the hybrid composite reaches a percolation critical concentration of 2.14×10-4 S/cm by Ag doping. For all PMMA/MWCNT/Ag hybrid composites, the frequency-dependent dielectric constant decreases as the frequency area widens. As the concentrations of MWCNT and Ag increase, the AC conductivity exhibits an increasing trend. The MWCNT and Ag content was found to significantly affect the SE of the given composites. A high electromagnetic (EM) shielding efficiency (SE) was achieved between 8.2 and 12.4 GHz (X-band). The highest EM attenuation of 18 dB at 12 GHz was achieved using 0.5 wt% MWCNT and Ag. The thermal analysis of the formed PMMA/MWCNT/Ag hybrid composites showed that exothermic reactions with the greatest weight loss took place between 200°C and 300°C. FESEM show that PMMA/MWCNT/Ag hybrid composites had uniform dispersion of the carbon nano tube and silver particles within the PMMA matrix .

In this study, the Density Function Theory (DFT), Generalized Gradient Approximation (GGA) and Local Density Approximation (LDA) were used, based on the Siesta code, in order to study the magnesium oxide compound (MgO) and focus on the (B4) Wurtzite phase. This is to find the primary cell constants and energy gap at 0 pressure, which are consistent with previous results. The effect of pressure on the energy gap and the size of the primary cell as well as the dielectric constant were studied. The study also revealed that the (B4) phase can move to the (B2) phase at the pressure of 45.86 GPa and from the h-MgO phase to the (B2) phase at 70 GPa.

Published: October 2023

Based on the diffusion technology, many scientists and specialists have conducted research on obtaining materials that are fundamentally different in electrical and photo-thermal parameters from the original material by introducing various input atoms into semiconductor materials and creating deep energy levels in their band gap. The electrical, photoelectric, optical, and magnetic properties of these semiconductor materials have been extensively studied with metal group elements, isovalent elements, and rare earth elements added to silicon through the process of growth, ion implantation, or diffusion from the gaseous state. The technology of introducing impurity atoms into silicon by the diffusion method is distinguished from other methods in its simplicity, energy efficiency, and low cost. Up-to-date, the technology of changing the resistivity and conductivity of the initial sample by diffusion of manganese atoms into single-crystal silicon is studied insufficiently. In the article, it was determined that when manganese atoms diffuse into silicon, a high-manganese silicide is formed on its surface and in the near-surface layer. Based on the analysis of the experimental results, the thermal EMF (electromotive force) in Mn4Si7-Si -<Mn>-Mn4Si7 structures in a certain temperature range and under illumination (with monochromatic or integrated light) is explained by the fact that it based on the Pelte effect, observed in semiconductors.The volt-ampere characteristics (VAC) of the obtained structures were measured at various temperatures, in the dark and in the light. Formation of a boundary layer with high resistivity at the boundary of the higher manganese-silicon transition, the transition from higher manganese silicide to the base of the structure due to the effect of ionization of pores during illumination of structures and external influence. The applied field was clarified based on VAC results. The manganese high silicide layer formed on the silicon surface has the properties of a semiconductor, and the formation of a heterojunction upon transition to silicon is shown on the basis of the sphere diagram.

Published: October 2023

Purpose: The objective of this research was to conduct a comparative and dosimetric analysis of three different radiotherapy techniques used in lung stereotactic body radiotherapy (SBRT), the three-dimensional conformal radiotherapy (3DCRT), intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT), using a 10 MV flattening filter-free (FFF) photon beam. Materials and methods: The present study employed computed tomography (CT) images of a humanoid phantom for the purpose of treatment planning. The gross tumour volumes (GTVs) delineated in both the central and peripheral positions of the lungs. The determination of Planning Target Volumes (PTVs) involved the addition of a margin of 0.5 cm to the Gross Tumour Volume (GTV). Three-dimensional conformal radiotherapy (3DCRT), intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT) treatment plans produced employing a 10-megavolt (MV) flattening filter-free (FFF) photon beam. The calculation of dosage for all plans Performed using the anisotropic analytical algorithm (AAA). Results: IMRT and VMAT had better PTV dose conformation than 3DCRT for both central and peripheral targets. PTV conformity improved in VMAT compared to IMRT, and CI values were acceptable for VMAT, IMRT, and 3DCRT plans. VMAT plans had slightly better CI than IMRT, with better results in peripheral lung PTVs compared to central PTVs. VMAT and IMRT are superior for treating HDV and D2cm, with lower HDV for peripheral lung tumours. Both 3DCRT and IMRT improved outcomes for peripheral lung PTVs, while VMAT was better for central lung PTVs. The former proved better with less low lung doses and improved D2cm results. 3DCRT plans demonstrated higher precision in dose distribution than VMAT and IMRT plans, with superior average GI values. VMAT and IMRT had higher HI, Dmax, and D2% than 3DCRT. VMAT plans compared to IMRT plans, with similar HI values for central lung PTVs. VMAT better spares OARs than other techniques, but V20 and V30 lung doses were lower with 3DCRT. VMAT increases lung dose, but OAR stays below thresholds.
Conclusion: The investigation found that all three treatment techniques can deliver SBRT plans that meet RTOG dose constraints. However, VMAT is a better treatment strategy than IMRT and 3DCRT for both peripheral and central lung PTVs, based on dosimetric indices like CI, D2cm, HI, and HDV. The study found that 3DCRT improves dosimetric indices, especially gradient index (GI), more than VMAT. Despite the need for more monitor units (MUs) in VMAT plans, treatment time reduced due to faster gantry velocity and higher dose rates (2400cGy/min) via free flatting filter energy.

Method: Description of a Case Report Diffuse Large B-Cell Non-Hodgkin Lymphoma with a spontaneous bowel perforation: A 39-year-old female patient presented with a one-day history of acute abdomen. She is known retroviral disease reactive with CD4 count 534, Viral Load 131 on Antiretroviral Treatment-Fixed Dose Regimen duration of more than 5 years and was being treated for Peptic Ulcer Disease. Chest X-ray: showed pneumoperitoneum consistent with a perforation. A Laparotomy was performed and found a perforated Jejunum leaking small bowel contents. Resection and primary anastomosis were performed, and washout was done. Post-Operative condition was uneventful, and she was discharged four days after the operation. The resected portion was sent for histology, which showed perforation of the Jejunum secondary to a Diffuse Large B Cell Non-Hodgkin Lymphoma. Conclusion: The diagnosis of Intestinal Lymphoma poses a diagnostic challenge for both developed and developing countries; however, coupling the risk factors with signs and symptoms can assist one in making a diagnosis. It is therefore important to always have a high index of suspicion, particularly for HIV patients with lymphadenopathy. Doi: 10.28991/SciMedJ-2023-05-01-05 Full Text: PDF

Research aim: The study aims to assess the value of the impact of PT PLN UIK TJB's CSR program on the implementation of social innovation in Tubanan agroforestry. In this approach, the effect of the program has an essential meaning for the beneficiaries of the program, namely the farming community group in Tubanan Village.
Design/Methode/Approach: This study used social return on investment (SROI) as a research methodology. This research was conducted on the beneficiaries of the Tubanan agroforestry program and considered all stakeholders directly or indirectly involved in the program. The research informants numbered 20 people who were members of the LMDH Tunas Agung in Tubanan Village.
Research Finding: The results showed that the CSR programs generated social benefits on investment and provided economic, social, and environmental benefits. SROI as a solution that changes the mindset of investment analysis based on outcomes is not just output.
Theoretical contribution/Originality: This study allows us to expand the evidence of the critical role of social innovation for farming community groups, but so far, little has been studied about the application of SROI as an assessment methodology.
Practitionel/Policy implication: The results of the SROI analysis become the basis for improving the planning of subsequent CSR programs.
Research limitation: The selection of financial results and the proxies used are potentially biased, even though the proxies have been quantified over a potential range, the impact value has been reduced by filters (deadweigh, attribution, displacement, drop-off), and only emphasizes the impact on hard results rather than soft ones, which are considered less valuable.

Background: neurodegenerative processes are prognostically dramatic conditions. They are actively studied by both neurologists and psychiatrists. Nosological forms are diverse and include regressive autism, dementia, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, progressive epilepsy of infancy and childhood, generalized hyperkinesis, Tourette’s syndrome and many other conditions that are common to progressive neurological deficit, loss of cognitive functions, the appearance of nonspecific symptoms of brain irritation (epileptic seizures, hyperkinesis, dystonic states, stereotypes, psychotic episodes and other symptoms). Despite many ongoing studies the treatment of the described conditions is limited to temporary, incomplete and pharmacologically dependent relief of symptoms, since the problem of the etiopathogenesis of these conditions remains open. The aim of review is to present current immunological concepts of pathogenesis of neurodegenerative diseases. Material and method: using keywords “neuroinflammation, neurodegeneration, multiple sclerosis, Parkinson disease, epilepsy, parasitosis, microbiota” selected relevant scientific publications in domestic and international databases. Conclusion: recent advances in neuroimmunology show a significant role of neuroinflammation in the triggering and development of neurodegenerative processes, some of which are autoimmune in nature, which is confirmed by the indicators of immunity intensity introduced into clinical practice and by the detected antibody titers to brain tissues. In recent decades in a series of scientific works attention has been paid to the study of infectious agents detected in the immunological screening of patients with neurodegeneration, however, these data are fragmented and contradictory, and therefore are ignored by the medical community. This review presents a modern view of the etiopathogenesis of neurodegenerative diseases from the point of view of the summative antigenic burden, assessment of the immunological potential, homeostatic resource, and compensatory capabilities of the human body, which as a result can become a starting point for proposing new therapeutic strategies for the treatment of these intractable diseases.
