    The present study was aimed to evaluate the characteristics of the olive barb sperm. Milt was collected fortnightly from 49 male fish (mean weight 90.8 g and length 18.64 cm) from April to July in 2008. In the olive barb ejaculated milt, volume (µl/g), motility (%), duration of motility (s), concentration (x 10 super(10)/ml) and pH values were found to be 6.06±0.32, 88.27±0.71, 171.41±7.41, 5.16±0.05 and 7.75±0.04, respectively. Milt volume was significantly (P<0.05) correlated with sperm concentration. Milt volume, sperm concentration, motility and duration of motility significantly varied (P<0.05) during spawning season

    An application for solving truth functions

    Get PDF
    Nowadays, many technical devices are controlled by logic circuits. These circuits evaluate the situation based on the proposed truth functions, which they then use to perform one of the defined actions. In line with the increasing complexity of individual technical devices, the logic circuits and truth functions are also increasingly complex. For this reason, it makes sense to minimise these functions since they can thereby achieve a simpler technological process and the higher reliability of whole logic systems. This paper describes the Karnaugh Studio application, which resolves the minimisation of these truth functions - and was developed at our faculty (FAI, TBU in Zlín). The minimisation is performed using the Karnaugh Map Method - with support for up to eight variables on input. The application is based on the C++ programming language and the Dear ImGui and Magick++ libraries. Its functionality has been verified on a number of examples. This proved its applicability and ability to be used in the solution of logic circuits in industrial practice. © 2020, Springer Nature Switzerland AG

    Risk stratification of newly diagnosed multiple myeloma patients

    Background: Multiple Myeloma is a neoplastic proliferation of plasma cells, associated with an M (monoclonal) protein in serum and/or urine and evidence of organ damage. Despite advances in treatment, the disease remains heterogeneous, necessitating a comprehensive understanding of its risk stratification. Risk-adapted initial therapy, maintenance therapy, refractory disease management and prognosis varies according to risk group. The aim of our study is to categorize the newly diagnosed MM patients according to their risk groups. Methods: This cross-sectional observational study was conducted at the Department of Haematology of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, from August 2019 to July 2020. A total of 31 newly diagnosed MM patients were enrolled based on specific inclusion and exclusion criteria. Risk stratification was performed using ISS, R-ISS, mSMART criteria and Avets risk group categorization. Result: The majority of the patients were male (64.52%) and aged between 55-64 years (45.16%). Clinical features predominantly included low back pain (74.19%) and general weakness (38.71%). Cytogenetic abnormalities were noted in 38.7% of the patients, with del (13q) being the most common (32.30%). Most patients were in ISS Stage III (70.97%) and R-ISS Stage II (48.39%). According to mSMART criteria, 80.65% were at standard risk while Avet's risk stratification identifies 58.06% were at intermediate risk. Conclusion: The study reveals a high prevalence of patients in advanced ISS stages and intermediate to high-risk categories, emphasizing the need for early and personalized intervention strategies

    The latent digital divide and its drivers in e-learning among bangladeshi students during the COVID-19 pandemic

    The devastating COVID-19 pandemic forced academia to go virtual. Educational institutions around the world have stressed online learning programs in the aftermath of the pandemic. However, because of insufficient access to Information Communication Technology (ICT), a substantial number of students failed to harness the opportunity of online learning. This study explores the latent digital divide exhibited during the COVID-19 pandemic while online learning activities are emphasised among students of Bangladesh. It also investigates the digital divide exposure and the significant underlying drivers of the divide. In order to accomplish this, a cross-sectional survey was employed to collect quantitative data, mixed with open-ended questions were utilised to gather qualitative information from the student community. The findings revealed that despite the majority of students having physical access to ICT, only 32.5% of students could attend online classes seamlessly. In total, 34.1% reported data prices as the critical barrier, while 39.8% identified poor network infrastructure as the significant barrier preventing them from participating in online learning activities. Although most students possess physical access to various devices and the Internet, they face the first-level digital divide due to the quality of access and price of cellular Internet. Consequently, they fail to take advantage of physical access, resulting in the third-level digital divide (utility gap), which submerges them into a digital divide cycle. The primary objective of this study is to explore the underlying issues of the digital divide among Bangladeshi students. This will assist relevant stakeholders (e.g., the Bangladesh government, educational institutions, and researchers) to gain necessary insights and theoretical understanding of underlying limitations and emergent directions to arrange adequate support for underprivileged students to undertake essential online learning activities

    Abstract: Genetically Improved Farmed Tilapia (GIFT) is one of the most successful one of all exotic fish species in Bangladesh from the view of acceptance and prevalence in cultured water bodies. Manual separation of male and female tilapia is one of the methods for obtaining single sex. In Bangladesh, abundance of sex reversed GIFT male is very limited, therefore, the experiment was conducted to compare the yield of manually separated 1 1 GIFT with others. Highest yield (5285.3±289.9 kg haG) and gross return (358343.7±23555.6 tk haG) were found from manually separated male GIFT, which was significantly different from others. Even manually separated female GIFT gave the better production than culture of both sexes together and of carps also
