Good health depends on moderate and proper nutritional food. There is a noticeable difference in eating patterns between individuals living in rural and urban regions. The central aspect of this study is to make a comparative analysis of the health of rural and urban people with their eating habits. In February 2022, data were collected from 1,400 people in Bangladesh’s major cities through offline and online surveys and analyzed using IBM SPSS Statistics 25 and Microsoft Excel. Three types of correlation are brought out among the selected parameters, such as local people will be able to protect themselves from heart disease by consuming vegetables. The paper highlights the staple food of people of all ages in Bangladesh as well as their daily food intake time and quantity through a comprehensive survey. People will be able to adjust their health depending on the type and amount of food they consume, and they will also be able to know whether urban people are ahead of rural people and vice versa. This research can bring good health to the people by reviewing the food habits of the people of the village and the city.

Abstract Background The surge in digital media consumption, coupled with the ensuing consequences of digital addiction, has witnessed a rapid increase, particularly after the initiation of the COVID-19 pandemic. Despite some studies exploring specific technological addictions, such as internet or social media addiction, in Bangladesh, there is a noticeable gap in research focusing on digital addiction in a broader context. Thus, this study aims to investigate digital addiction among students taking the university entrance test, examining its prevalence, contributing factors, and geographical distribution using GIS techniques. Methods Data from a cross-sectional survey were collected from a total of 2,157 students who were taking the university entrance test at Jahangirnagar University, Bangladesh. A convenience sampling method was applied for data collection using a structured questionnaire. Statistical analyses were performed with SPSS 25 Version and AMOS 23 Version, whereas ArcGIS 10.8 Version was used for the geographical distribution of digital addiction. Results The prevalence of digital addiction was 33.1% (mean score: 16.05 ± 5.58). Those students who are attempting the test for a second time were more likely to be addicted (42.7% vs. 39.1%), but the difference was not statistically significant. Besides, the potential factors predicted for digital addiction were student status, satisfaction with previous mock tests, average monthly expenditure during the admission test preparation, and depression. No significant difference was found between digital addiction and districts. However, digital addiction was higher in the districts of Manikganj, Rajbari, Shariatpur, and Chittagong Hill Tract areas, including Rangamati, and Bandarban. Conclusions The study emphasizes the pressing need for collaborative efforts involving educational policymakers, institutions, and parents to address the growing digital addiction among university-bound students. The recommendations focus on promoting alternative activities, enhancing digital literacy, and imposing restrictions on digital device use, which are crucial steps toward fostering a healthier digital environment and balanced relationship with technology for students.

Heavy metal (HM) poisoning of agricultural soils poses a serious risk to plant life, human health, and global food supply. When HM levels in agricultural soils get to dangerous levels, it harms crop health and yield. Chromium (Cr), arsenic (As), nickel (Ni), cadmium (Cd), lead (Pb), mercury (Hg), zinc (Zn), and copper (Cu) are the main heavy metals. The environment contains these metals in varying degrees, such as in soil, food, water, and even the air. These substances damage plants and alter soil characteristics, which lowers crop yield. Crop types, growing circumstances, elemental toxicity, developmental stage, soil physical and chemical properties, and the presence and bioavailability of heavy metals (HMs) in the soil solution are some of the factors affecting the amount of HM toxicity in crops. By interfering with the normal structure and function of cellular components, HMs can impede various metabolic and developmental processes. Humans are exposed to numerous serious diseases by consuming these affected plant products. Exposure to certain metals can harm the kidneys, brain, intestines, lungs, liver, and other organs of the human body. This review assesses (1) contamination of heavy metals in soils through different sources, like anthropogenic and natural; (2) the effect on microorganisms and the chemical and physical properties of soil; (3) the effect on plants as well as crop production; and (4) entering the food chain and associated hazards to human health. Lastly, we identified certain research gaps and suggested further study. If people want to feel safe in their surroundings, there needs to be stringent regulation of the release of heavy metals into the environment.

The fungal disease Verticillium wilt is a soil-borne pathogen that is caused by Verticillium dahliae. This disease affects a wide range of crops and can cause significant yield losses. Recent findings suggest that Verticillium wilt has been affecting potato crops in abundant domains around the global world, including in North America, parts of Europe, and Asia. In some cases, the disease has been observed in fields where it has not been previously reported, indicating that it has been spreading. Farmers and researchers are working to manage the disease through a variety of measures, including rotation of crops, the use of resistant varieties of potato developed from resistant strains, and the application of fungicides. However, the potency of these measures can vary depending on the ferocity of the disease and the local growing circumstances. Overall, the recent findings of Verticillium wilt in potato underscore the importance of continued monitoring and research to better understand the disease and develop effective management strategies. This review has highlighted the up-to-date information on Verticillium wilt and management strategies. The study also helps the scientific community understand this devastating plant disease by offering a thorough review of the situation.

The production of sustainable crops and environmental management in farming face several significant potential obstacles, including climate change, resource depletion and environmental degradation. Weeds and insect pests that considerably reduce yields have put crop production systems in danger. The greatest worry for farmers is the decline in productivity due to illnesses and pests. Insects, weed pests, and plant pathogens destroy more than 40% of all potential food production every year. The widespread use of integrated pest management (IPM) is a result of worries about the long-term viability of conventional agriculture. IPM ensures sufficient, secure, equitable, and steady flows of both food and ecosystem services, as well as increased agricultural profitability due to lower pest management expenditures. A number of studies conducted on IPM have been combined. Important information from all these studies was analyzed and summarized in this literature review. In this article, we investigated the following: (1) explanation of different management components; (2) development in organically integrated weed and insect pest management, with possible ramifications and scope; (3) knowledge and adaptation status of IPM in the modern world; (4) resources and tools of IPM; (5) current challenges and suggested future research priorities. Regular training related to IPM should be arranged to spread the knowledge of IPM to all farmer levels. This requires the cooperation of the government. Furthermore, IPM will reach a new milestone if Internet of Things technology is practiced along with the existing pest control method. Overall, this review addresses the possibilities for researchers and farmers to use a variety of natural control agents as a full or partial replacement for synthetic pesticides.

Microplastics are currently a major global threat as they enter the ecosystem in large quantities daily and are able to persist in the environment for a long period of time. Current research focuses mainly on aquatic and related ecosystems; however, little information is available on the sources, possible accumulation, and pathways of microplastics in agroecosystems. It was previously thought that plastic particles could not be taken up or accumulate in plant bodies, but with modern technology, it has been observed that plastic particles are able to penetrate plants at the micro and nanoscales through transpiration pull forces, and in some cases through the leaves with foliar application. The purpose of the study was to identify potential sources of microplastics, their ways of entry into agroecosystems as well as into plants, and the effects of microplastics on the physiological processes of plants. We highlighted the harmful effects of these pollutants on agricultural ecosystems. Microplastics causes pore space blockages on root surfaces and oxidative damage. Moreover, they inhibit nutrient and water uptake, decrease germination capability, and have negative effects on product quality.

The use of smartphones has improved individuals significantly in this age of information technology. Yet farmers cannot use this smartphone due to a lack of proper knowledge. Where smartphones could easily be used by farmers to solve their agricultural problems. The aims of the study to improve the daily life of a farmer as well as to gain skills in the use of smart phones. Nine characters have been selected to find out the relation between knowledge of farmers' use of smartphones in agriculture. The data are collected through interviews from 128 farm families from Mymensingh of Bangladesh. A semi-structured questionnaire is distributed for collecting data. Those data were pre-arranged and categorized by using M.S. Excel. Spearman's Rank Order were used to create correlations among the characteristics of farmers. Among the selected farmers 56% have low knowledge and only 3% of farmers have high knowledge about the use of smartphones in the agricultural sector. Among nine characters ages and firm experience have a strong negative significant correlation (-0.548* and -0.541*, respectively). On the other hand, extension media interaction has a strong positive relationship (0.588*). From this output, farmers will be able to gain a complete understanding of smartphones to solve the agricultural problems with proper training and experience.

Introduction: Anemia of prematurity (AOP) is a common problem of very low birth weight (VLBW) babies. Blood transfusion is a necessity when it occurs in moderate to severe form putting the child in to the risk of transfusion related complications. Erythropoietin, a potent stimulator of hemopoesis is available in breast milk in good amount and absorbed intact under physiologic condition. In this background oral recombinant human erythropoietin (rhEPO) can be a useful alternative to its subcutaneous administration in prevention of AOP. Methods: This randomized controlled study was conducted in the NICU of BSMMU from Jan-15 to Dec-15. Total 60 preterm ( 0.05). Similar weight gain was recorded in both groups. One neonates in each group required blood transfusion. Conclusion: Administration of oral rhEPO in preterm VLBW infants after the first two weeks of life along with iron and folic acid supplementation stimulated erythropoiesis, increased weight gains and the need for red cell transfusions similar to that of subcutaneous rhEPO.

Background and Aim: Subclinical mastitis (SCM) is an economically important disease for dairy cattle worldwide; therefore, regular screening is imperative to detect SCM at an early stage so as to control it. The study was conducted to compare the test characteristics of sodium lauryl sulfate (SLS) as a test reagent to detect SCM in dairy cows. Materials and Methods: First, 106 milk samples of dairy cows were subjected to available indirect screening tests (white side test [WST], surf field mastitis test, Leucocytest, and Immucell) considering somatic cell count (SCC) as gold standard test. Then 273 milk samples were allowed to react with different concentrations of SLS with or without sodium hydroxide (NaOH) and indicators (bromothymol blue [BTB] and bromocresol purple [BCP]). Results: SLS with or without NaOH yielded best reaction with the milk samples similar to Leucocytest. It was observed that the reaction of milk samples with SLS added with indicators (BTB and BCP) was easier to visualize than without indicators. SLS 3%+NaOH 1.5% with BTB and SLS 2% with BCP had high sensitivity, specificity, and substantial agreement with SCC. The area under the receiver operating characteristics curve of SLS 2% with BCP and SLS 3%+NaOH 1.5% with BTB was 0.917 and 0.875, respectively. Conclusion: It may be concluded that SLS 3%+NaOH 1.5% with BTB and SLS 2% with BCP may be the potential reagents for the development of an effective cow-side test to detect SCM, as the main ingredient SLS is considerably cheap and readily available in developing countries.

Battery management systems can measure the performance of batteries. Most significantly, they can estimate expected run time under certain discharge conditions. The calculation is defined as the average current coming from the battery multiplied by the time it takes to reach a safe cutoff point of the battery. These two variables, average discharge current and duration, are directly proportional to each other. Using the average current and time multiplied together provides amp hour rating. An efficient and low cost way to measure these values is by using a microcontroller such as Arduino Nano [1]. The Arduino determines average discharge current and can record time to estimate the Ah rating of the battery. After some fine adjustment using designing methods, the system was obtaining acceptable values from discharging tests using a EFest IMR18650 2Ah Li-Mn battery. Using a standard battery datasheet, the proper shutoff voltage was determined to be 2.5V [2]. The test results were within our acceptable range on the printed battery Ah value. The voltages were then plotted in Matlab using a CSV file created by the serial monitor print out from the microcontroller.

Goal of this research is to improve the capability of ultrasound images for detecting breast microcalcifications (MCs) and remove the major barriers of ultrasound for early breast cancer detection. The low detection rate of MCs with ultrasound is due to the low spatial resolution of the ultrasound images and to the presence of speckle noise, which masks the tiny microcalcifications. The first objective of this project is to investigate the efficiency of time reversal multiple signal classification (TR-MUSIC), algorithm in detecting breast microcalcifications and we did our experiments on numerical phantoms for detecting point microcalcifications and got the

Early detection is key to surviving breast cancer. The earliest indication of potential breast cancer detectable by current screening methods is the presence of microcalcifications. The low efficiency of ultrasound in detecting these microcalcifications is due to several factors, including the low spatial resolution of the ultrasound images and the speckle noise, which masks the tiny microcalcifications. This paper aims to investigate the efficiency of the time reversal multiple signal classification algorithm in detecting breast microcalcifications. Experiments were performed on numerical phantoms, and results show that the TR-MUSIC algorithm efficiency depends on several parameters.

We used PIC18F452 microcontroller for hardware and software implementation of our home security system design. Based on PIC18F452, our system can monitor doors and windows of a house and can set alarm and warming signal to a nearest police station if anybody tries to break in. This security system also provides the functionality to identify the residents ID card to get access to the house without turning on the warning signal and alarm. Also, the security system provides a status that is not monitoring the door and windows since there is some possibility that the host do not want the system always checks the status of their house.

Mastitis is a serious problem for the dairy cattle in many countries of the world including Bangladesh. Among the microbial etiology bacteria plays a major role in the onset of the clinical form of the disease. Many of these bacteria are resistant to one or more antibiotics thus make the mastitis cases difficult to cure. In the present study Staphylococcus spp., Streptococcus spp., Bacillus spp. and E. coli were identified as the dominant bacterial species causing clinical mastitis in cattle in Mymensingh. Antibiogram study revealed chloramphenicol and erythromycin as the most effective antibiotic for the treatment of mastitis in these animals except those caused by Bacillus spp. and E. coli, respectively.
