This research aims to analyze the determinant of capital structure and profitability. Besides, it will also be tested to know whether there is a reciprocal relationship between this capital structure and profitability or not. The object of this research is using the registered manufacture company on the Indonesian Stock Exchange. The number of companies pointed as the samples in this research is 115 companies. The observation period is between 2012 – 2018 or for about 7 years so that the analysis units of this research are 805. The analysis tool used in this research is the Structural Equation Modeling by using generalized structural component analysis. It creates the results of Nondebt tax shield, effective tax rate, financial flexibility, liquidity; growth, uniqueness, assets utilization, firm size, tangibility, volatility, and profitability have an impact on the capital structure. It is known that only a firm age that doesn’t have any significant impacts on the capital structure. Liquidity, growth, firm age, uniqueness, firm size, tangibility, volatility, advertising, assets turnover, and capital affect profitability. Besides that, capital structure and profitability have a significant reciprocal relationship.

Techniques for recognizing and mapping of land-slides are complex in mountainous terrains. Most of the methodsapplied to landslide identification and prediction involves assign-ment of different contributing factors in landslide hazard zonation;digital elevation modeling capabilities and Guided Visual Program(GVP) module of Datamine Software is utilized to successfullyenumerate the various contributing factors for causing the land-slide in Sikim, Eastern Himalaya in the case study of ChandmariLandslide. A landslide warning system is discussed for the site-specific Chandmari landslide area.

Piezoelectric-magnetostrictive (magnetoelectric) composites using piezoelectric lead zirconate titanate (PZT) ceramic and magnetostrictive Ni-Zn ferrite (NZF) with compositional formulae (1-x) PbZr0.65Ti0.35O3-x Ni0.8Zn0.2Fe2O4 with x = 0 to 0.15 in steps of 0.05, were prepared by a conventional solid state route. The presence of individual phases was confirmed using X-ray diffraction. Dielectric properties were studied as a function of temperature and frequency presuming that the interactions between the piezoelectric and magnetostrictive phases may result in various anomalies in the dielectric properties of these composites. To study the ferroelectric properties, P-E hysteresis loops were recorded.

Objectives: The coronavirus disease (COVID-19) pandemic and news of daily increasing cases inside Nepal and worldwide is adding to the fear that leads to anger, anxiety, frustration, and stress, emotions that directly affect sleep quality. This study aimed to assess sleep disturbances during the COVID-19 pandemic in a Nepalese population.Methods: This cross-sectional study recruited 206 Nepali residents who completed anonymous self-administered questionnaires. The Insomnia Severity Index (ISI) questionnaire was used to measure sleep disturbances before and after the COVID-19 pandemic. The gathered data were analyzed using descriptive statistics and inferential statistics using SPSS version 20 statistical software.Results: There was a significant variation in sleep disturbances among Nepalese residents before versus after the COVID-19 pandemic (p<0.001). The prevalence of clinical moderate insomnia has increased tremendously in Nepalese individuals. Before the pandemic’s onset, only 3.9% of the participants had moderate to severe levels of clinical insomnia; after its onset, this value increased to 17.5%. The mean ISI scores were 6.35±4.65 and 8.01±6.01 before and after the pandemic’s onset, respectively.Conclusions: Our study findings suggest that people are suffering tremendously with sleep disturbances and calls for further research and active measures to help increase sleep quality during the COVID-19 pandemic.

A 38-year-old woman who presented with unexplained fever and pancytopenia was subjected to a bone marrow examination. Her bone marrow aspirate smear showed no obvious pathological finding except for the presence of hemophagocytosis and mild plasmacytosis. In view of hemophagocytosis, a thorough examination of the smear was conducted and revealed the presence of histoplasmosis. She was advised to undergo evaluation of her immunological status, and she tested positive for human immunodeficiency virus (HIV) infection. This case highlights that hemophagocytosis in the marrow may be an early sign of underlying disease, and that careful examination of bone marrow smears may reveal subtle infections. In addition, histoplasmosis with hemophagocytosis may be associated with pancytopenia, and hence, the HIV status of the patient should always be investigated.
