Continuous monitoring of progress of a clinical trial is known as health monitoring. It is to assure compliance with policy, best clinical practice, regulatory norms, and standard operating procedures. Monitoring is vital in several health settings. This creates an environment where physician and patient can engage. The doctor may also be up to date with the current patient’s health status. Sensor initialization is this system's first stage. This project includes of many sensor kinds such as blood pressure sensor, temperature sensor, pulse rate sensor. The sensor is then connected to the Raspberry Pi 3 Model B+ which transmits a signal over the internet allowing the doctor to interact with patient data. All sensor data is stored in a cloud database. If the sensor value exceeds the threshold sensor value and the alert email is sent to the doctor and caretaker, then a precautionary notification is sent to the patient. Doctor and patient can interact through a user application where the doctor can even write the patient's prescription. This approach can monitor several patients in severe conditions and save time. This project provides low-cost monitoring from one's home. This is a secure and reliable project that helps patients worldwide.

Effluent is wastewater flowing out of a sewer which constitutes environmental problems ranging from long-term ecological damage to increased water-borne diseases. In Nigeria, palm kernel oil is extracted from oil palm fruits in oil mills and the effluent is discharged without treatment to the soil in the vicinity of such mills. The effluent-receiving soil has been observed not to support the growth of vegetation. Hence in this work, the impact of palm kernel oil mill effluent on the soil physicochemical characteristics and growth of tomato plant was determined and compared with the effluent discharge limit established by the Federal Environmental Protection Agency. Samples of untreated and treated effluent, untreated and treated effluent-polluted soil and unpolluted soil were used for the study. The physicochemical analysis was carried out using standard physicochemical methods. The physicochemical values of the untreated effluent, except the pH, which was acidic, were higher than those of the treated effluent. Most of the physicochemical values of the untreated effluent-polluted soil were higher than those of the treated effluent-polluted soil and the unpolluted soil. The tomato plant grown in the unpolluted soil had better growth characteristics and yielded more fruits than those grown in the treated effluent-polluted soil. In addition, the tomato plant grown in the untreated effluent-polluted soil showed the lowest growth characteristics and yielded no fruits due to its elevated level of heavy metals and total petroleum hydrocarbons. The study showed that the untreated palm kernel oil mill effluent had a negative impact on the soil's physicochemical and growth characteristics of the tomato plant. Therefore, the effluent must be adequately treated to remove hazardous substances before its discharge into the terrestrial environment.

The prosperity of a country is highly dependent on its public health. Bangladesh is very keen to achieve a sustainable public health sector as a developing country. Bangladesh reached the goal of MDG (Millennium Development Goals) and pursued the goal of SDG (Sustainable Development Goals). Without sound public health, it is impossible to achieve SDG. So, Bangladesh is investing a good amount of money in the public health sector. As a part of this grand vision, this research has been conducted on the disease demography of Bangladesh. An interested pharmaceutical company collected prescription data from all administrative districts of Bangladesh, and weather and population data have been collected as a part of this work. An in-depth analysis of these data has been performed to discover insights into Bangladesh’s disease demography. Finally, a set of recommendations has been presented to assist the public health sector of Bangladesh.

Good quality water is indispensable to human and animal existence. Storage facilities are commonly used to ensure sufficient water, predominantly where piped water supply operates occasionally. Therefore, water samples from five boreholes were analyzed before and during storage for three weeks in household plastic containers using standard physicochemical methods. There was an increase in pH, temperature, electrical conductivity, total dissolved solids, total solids, turbidity, nitrates, phosphates, sulfates, alkalinity, copper, and lead and a decrease in dissolved oxygen, chlorides, total hardness, total acidity, zinc, cadmium, iron, and chromium. In contrast, the total suspended solids remained unchanged during storage. The physicochemical parameters were within the World Health Organization Standard for drinking water quality except for the pH, total acidity, cadmium, and lead levels during storage. This study showed that water storage for three weeks in plastic household containers adversely affected the physicochemical quality of the water. Therefore, water must not be stored for an extended period in plastic containers to avoid deterioration in its quality.

COVID-19 pandemic has impacted all facets of society, including students, as daily learning activities were severely affected while the face-to-face classes were forced to be held online. As a result, students underwent tremendous stress and were exposed to severe mental health conditions. Thus, this study investigates how the integration of casual video games into online learning can relieve stress among science students. An online survey was designed and disseminated to students via social media. The respondents were pre-assessed for stress and emotional conditions during their online learning. Then, the respondents were instructed to watch a tutorial video from YouTube and play a quiz-like casual video game that we had developed. The respondents were then reassessed for stress and emotional level (post-assessment) to understand how casual video games can relieve their anxiety in online learning. All questionnaires in this survey were tested for the Likert scale, with one being strongly disagreed and five strongly agreed. Similar pre-and post-survey questionnaires were designed and tested against academicians for their perceived efficiency of casual video games in online learning. The outcome from this study has shown significant improvements in students' stress and mental emotional levels when casual video game is introduced as part of their online lesson. On the other hand, the academicians perceived that online teaching alone is as effective as casual video games during online learning. However, the academicians also perceived that casual video games could significantly reduce students' stress and emotional during online classes. We propose that casual video games are considered an integral tool for online teaching and learning as they can significantly reduce students' stress in online learning during the Covid-19 lockdown.

Lung cancer is among the leading cause of death among men and women. Early detection of lung cancers can increase the possibility of survival amongst patients. The preferred 5-years survival rate for lung most cancers sufferers will increase from 16% to 50% if the disease is detected on time. Computerized tomography (CT) is frequently used for diagnosis and is more efficient than X-ray. However, the images need to be reviewed by a qualified physician who specializes in interpreting the CT scan. This may lead to misinterpretation and conflicting reports among physicians. Therefore, a lung cancer detection system that uses image processing methods to categorize lung cancer in CT images will be more consistent and precise. This paper presents a lung cancer detection system using the Artificial Intelligence (AI) method. The study uses Median, Gaussian, and Watershed segments to reduce noisy and shredded CT images. Then, the Weight Optimization Neural Network method was used to improve accuracy and reduce the computational time. The results were compared with previous works and shows higher accuracy and shorter computational time.

COVID-19 hit the world unexpectedly, forcing humans to isolate themselves. It has placed the lives of people in jeopardy with its fury. The COVID-19 has a detrimental effect on the world's education spheres. It has imposed a global lockdown, with a negative impact on the students' lives. Continuing regular classes’ on-campus were out of the question. At that moment, online learning came to us as a savior. The quality of online education was yet to be tested on a large scale compared to regular education. This paper reveals the factors that influence four programming courses from Computing students at X University and puts them on the table with an analysis backing it up so that, in future, authorities can design the proper structure for high quality online education.

Biodiesel is an alternative source of fuel that is non-toxic and biodegradable than conventional fossil-based fuel. In this research, biodiesel was produced by the cultivation of Chlorella sorokiniana in Palm Oil Mill Effluent (POME). The lipid content of the algae was obtained using the solvent extraction method. Gas-chromatography mass spectrometer was used for the identification of Fatty Acid Methyl Esther (FAME). Based on the results of biodiesel analysis, the components of FAME confirmed in microalgae biomass are mostly saturated fatty acid and they include tridecyclic acid (C13:0), myristic acid (C14:0), pentadecylic acid (C15:0), palmitic acid (C16:0) and stearic acid (C18:0). These indicated that the biomass of C. sorokiniana after POME treatment has the potential to be used for bioenergy production.

The old method used for examining data correctness is to recover the entire data from the cloud and then validate data reliability by scrutinizing the correctness of signatures or numeric values of the data as a whole. In modern cryptology, an essential problem to study here is to maintain the greatest benefit of the privacy of given information to perform multiple encryptions. The study shows how a decryption key is made stronger in the sense that it enables several ciphertexts to be decrypted without increasing their size. The statement of the problem lies in the fact that creating an effective public-key encryption system that supports flexible delegation is decipherable by a fixed-size decryption key that could be produced by the holder of the master-secret key. The solution to this problem is by presenting a definite type of public-key encryption known as key-aggregate cryptosystem (KAC). By using this method, users who hold master-secret key could convert a message through a public-key, and an identifier of ciphertext called “class”. This means that the ciphertexts could be further categorized into various classes. The main objective of this paper is to design a secure data storage system that provides multiple stimulating functions by which the storage system is divided and has no major authority.
