/in /by

COVID-19, caused by SARS-CoV-2, expanded worldwide because of its easier transmission process, which emerged as respiratory infections, multi-organ disorders, and asymptomatic effects. Though several vaccines have been invented to prevent the virus affection, still lots of people are affecting from mild to severe Covid. In this study, we mainly focus on the natural ways that helped the patients to cure COVID-19 in the recent post-covid scenario. Our goal is to find the effectiveness of protein-rich foods and physical activities that may reduce the risks and boost immunity to fight off SARS-CoV-2. This study was conducted in Bangladesh and data was collected from 208 cured people through face-to-face interviews, phone calls, and social media. It was found that protein-rich foods such as sea fish, river fishes, pigeon meat, lemon, ceevit, and physical activities such as walking, jogging, and pushing up were associated with a lower recovery period. Males has the higher recovery period after being cured than females.

The Impact of Exam Related Stress on Gastroesophageal Reflux Disease (GERD) Symptoms among High School Students in Bangkok

/in /by

Gastroesophageal reflux disease (GERD) is a digestive condition where the stomach’s acidic contents consistently flow back up into the esophagus which serves as the conduit linking the throat to the stomach. In most cases, individuals with GERD experience symptoms such as heartburn and regurgitation due to the weakening or improper relaxation of the lower esophageal sphincter. Stress, on the other hand, is an instinctive response that stimulates individuals to address challenges in the environment through adaptations to cope with the situation. Correspondingly, it has been frequently observed that high-stress intensities can significantly affect our bodily functions which could potentially progress to more severe disorders. Thus, we conducted survey research on high school students in Bangkok using an online questionnaire to determine the impact of exam-related stress on an individual’s development of symptoms related to Gastroesophageal reflux disease (GERD). The survey conducted in this research has shown that stress and anxiety from exams are correlated with a person developing GERD symptoms. Albeit it can be concluded that stress from exam expectations influences GERD, further research is required to identify other causes relating to this outcome. Therefore, it is crucial that individuals efficiently manage their stress as it has the potential to prevent the onset of GERD symptoms. Thus, examining the impact of exam-related stress on the development of GERD symptoms among Bangkok high school students can promote awareness about effective stress management to attain healthy well-being.

/in /by

Experiment aimed was determined the influence of using crude papain as coagulant on the chemical properties and energy value  of susu goreng based on goat  milk.  The completely randomized design (CRD) with 4 treatments and 4 replications was applied in this experiment. The crude papain levels tested consist of P1= 0.5%, P2= 1.0%, P3= 1.5% and  P4= 2.0% of milk volume. The variables measured was moisture, protein, fat, total sugar, lactose, calcium and energy value. Susu goreng obtained has moisture ranged of 52.99 to 54.08%; protein 24.88 to 29.05%; fat 22.30 to 25.75%; lactose 0.69 to 1.38%; total sugar 2.72 to 4.4%; calcium 0.68 to 0.77% and energy value 1989.28 to 2507.09 kcal/100 g. Analysis of variance showed that treatment had close significant effect (P<0.01) on total sugar, calcium and lactose, significant (P<0.05) on energy value but had no significant (P>0.05) on moisture, protein and fat. It can be concluded that the use of crude papain as a coagulant with a level of 0.5 to 2% produces susu goreng with varying chemical characteristics. The use of crude papain level 0.5% is the best where the susu goreng produced has the characteristics of the higher protein content, calsium and energy value, the lowest lactose content and total sugar.

Carbon Nanotube-Polyaniline Reinforced Flexible and Stretchable Strain Sensor with Enhanced Sensitivity for Smart Wearable and Skin-Mounted Applications

/in /by

Flexible and stretchable strain sensors have emerged as promising components for integration into smart wearable devices and skin-mounted applications. These sensors enable accurate detection of physiological signals, thereby finding unique applications in diverse fields such as human health monitoring, soft robotics, human-machine interface, prosthetics, virtual reality, and professional sports. Two commonly utilized types of strain sensors are capacitive and resistive strain gauges, owing to their low production cost, simplified circuitry, and ease of construction. While resistive strain gauges exhibit high sensitivity, they are prone to nonlinearity and hysteresis. On the other hand, capacitive strain gauges demonstrate linear behavior with minimal hysteresis but offer lower sensitivity. In this study, we capitalize on the exceptional properties of carbon nanotubes, including high mechanical strength, electrical conductivity, and thermal stability, along with using polyaniline as an exemplary conductive polymer. These materials are employed as a reinforcing phase within the polymer matrix, while the dielectric layer is comprised of Ecoflex® 00-30. An interdigitated pattern is specifically designed for this strain gauge to enhance sensitivity. Through this research, we aim to develop a flexible and stretchable strain sensor with enhanced sensitivity and improved performance characteristics.

Extraction and Characterization of Bio-Silica from Sri Lankan Traditional Rice Husks and Evaluation to TLC Application

/in /by

Rice husk (RH) is one of the most abundant agricultural wastes, but can be identified as a useful bio resource. Gonabaru, Kahawanu, Patchaperumal, Dahanala and Suwandel are five immerging traditional rice varieties, competing with genetically improved rice in Sri Lankan rice market. Ash content of RHs of traditional rice varieties (>20.0%) was comparatively higher than genetically improved rice. It was identified that additional acid washing step was essential to improve the purity of bio silica. Mineral impurities such as Na, K, Ca, Fe and Mn were determined using atomic absorption spectrometer (AAS). High silica content was extracted from RHs of traditional rice varieties (>23.0%) than that of improved variety, BW 364 (~16.2%). The functional groups present in Rice husk ash (RHA) and rice husk silica (RHS) were determined using Fourier transform infrared (FTIR) analysis. The potential application of purified RHS was observed by preparing and analyzing the thin layer chromatography (TLC) in comparison with commercial TLC silica.
