Due to its document exchange, virtual communication, and knowledge production capabilities, social media is a helpful tool for learning and teaching. The research embraces multiple goals. First, this study examines Bangladeshi university students' social value, communication and collaboration, trust, and perceived benefits of knowledge sharing through social media in academic advancement. The second goal is to examine how families and technology support mediates those aspects of social media knowledge sharing with student academic development. We used Technology Acceptance Model and Social Exchange Theory as examples of how social media sharing of knowledge impacts academic progress in Bangladeshi university students through family and technological support. PLS-SEM was used using survey data from 737 Bangladeshi students to test the model. Social value, communication and collaboration, trust, and percei...

The banking sector’s performance and profitability have been impacted as a result. In this paper, we analyze the effect of COVID-19 pandemic on the financial performance of banking sector in Bangladesh before and throughout the present era of COVID-19. Methodology: In this regard, the study considered the 14 banks over the period of 2014-2021. The random-effects regression model is utilized to identify the profitability drivers. The random effect model investigates the influence of bank-specific variables and macroeconomic variables on the profitability of banks. Findings: During the pandemic era of COVID-19, our article found that a high degree of nonperforming loans, retaining more liquid assets, and a significant amount of hedging funds reduced banks' profitability. In contrast, a suitable bank size, non-interest revenue, ...

Various treatment modalities have been reported in the literature with their merits, demerits and diverse success rate. Materials and Method: We report our experience in reconstruction of Ramal Condylar Unit (RCU) in temporomandibular joint ankylosis patients in a retrospective review. A total of 06 cases of TMJ ankylosis were included in the review. The cases were managed in our tertiary care centre from June 2019 to June 2020. Demographic distribution of the patients, preoperative findings, surgical modalities used for RCU reconstruction and postoperative outcome were recorded and compared. Results: Average mouth opening increased from 8.5 mm pre-operatively to 29.5 mm 3 months postoperatively. 02 cases of Sawhney’s type I and II ankylosis were managed by interpositional gap arthroplasty using temporalis myofascial...

The most common lung diseases are Asthma, Allergies, Chronic obstructive pulmonary disease (COPD), bronchitis, emphysema, lung cancer and so on. It is important to foresee the odds of lung sicknesses before it happens and by doing that individuals can be causes and make fundamental strides before it occurs. In this paper, we have worked with a collection of data and classified it with various machine learning algorithms. We have collected 323 instances along with 19 attributes. These data have been collected from patients suffering from numerous lung diseases along with other symptoms. The Lung diseases attribute contains two types of category which are ‘Positive’ and ‘Negative’. ‘Positive’ means that the person has a lung disease and so forth. The training of the dataset has been done with K-Fold Cross Validation Technique and specifically, five Machin...

This article outlines a virtual role-playing game where a user or gamer can do anything (which actions are loaded previously) in the virtual gaming environment There is growing attentiveness in the case of video games. The recent improvement of online, social joined video games (broadly multiplayer online role-playing games) now has created an experience for new gamers. A system in the Role-Playing Game (RPG) has some real-world scenarios that can be interconnected to the people of the real world, and some real action of life. An interactive environment in the gaming world has some characteristics that can participate in some action of the game based on the option available and in the choice of the user or gamer Developing a new 3D virtual environment by using a game engine strategy is to incorporate various multimedia data in one platform. Doing so we create the domain for a virtual reality console experience. We created this R...

The method is well suited for frequency-selective surface (FSS)-based absorbers. By employing the PPW structure, only a small sample size, i.e., 1-D array of FSS, is required for the measurement. The thru-reflect-line (TRL) calibration is implemented to remove the time-gating ambiguity in the conventional PPW-based method. A measurement system working up to 6 GHz is designed such that its length is adjustable to ensure all three calibration standards (thru, reflect, and line) can be carried out in a single device. Moreover, the height of the PPW is also adjustable to allow the measurement of absorbers with a different periodicity of FSSs. Two single-layer FSS-based absorbers with different periodicity are fabricated and measured. The results agree well with the conventional free-space measurement system, which validates the proposed method.

The specific absorption rate (SAR) values and total absorbed power in the human head phantom are used to evaluate EM absorption for both antennae. Moreover, antenna performances in terms of return loss, radiation efficiency, and gain are also investigated in this study. The finite integration technique (FIT) based on CST Microwave studio and SAM head phantom are used in this study. The antenna performances are measured in an anechoic chamber and the SAR is tested using COMOSAR measurement system. The obtained results indicate that the printed monopole antenna lead to higher EM absorption in the human head as compared to PIFA for both GSM frequencies.

The effects of the metal-glass casing of mobile phone on the SAR values were observed in the vicinity of the human head model. Additionally, the reflection coefficients were investigated in all cases to evaluate antenna performance. This analysis was performed by adopting finite-difference time-domain (FDTD) method on Computer Simulation Technology (CST) Microwave Studio. The results indicate that by increasing the distance between the user&#39;s head and antenna, SAR values are decreased.
