Recent studies show that parasites such as liver flukes have a capacity to bioaccumulate heavy metals significantly than the liver and muscle tissues of the host without compromising effects on them. One such heavy metal is lead (Pb) which is an abundant pollutant in the environment.Therefore, this study aimed to evaluate the effects of lead in the tegument of Fasciola gigantica (giant liver fluke) isolated from infected livers of carabaos in vitro using the following concentrations of lead: 0ppm, 110ppm, 160ppm, and 210ppm.

Statistics show that the primary cause of morbidity and mortality among Filipinos are pulmonary illnesses. These illnesses could have been prevented if detected and treated early. With the physicians medical knowledge and experience, early detection of possible common pulmonary diseases can be performed using a stethoscope. However, with the current physician-to-population ratio in the country, early detection of respiratory diseases may not be performed on most cases especially in the rural areas, causing even benign cases to lead to mortality.Â In this paper, we present the development of a system that classifies lung sound for possible pulmonary pathology.Using an electronic stethoscope, lung sounds were collected from healthy individuals and patients with common pulmonary problems for the developed systems training and evaluation. The collected data were pre-processed in order to remove mechanical and other external noises. Read More

This study focuses on the management of e-waste generated by the disposal of personal computers, laptops, and mobile phones because of the extraordinary growth in the use of these products over the past few years by the Filipino population. The aim was to explore the current methods of disposal of the aforementioned gadgets and to gather a baseline data in terms of the disposal methods of these three electronic gadgets within the geographical boundary of Metro Manila and the suburbs of Manila, Philippines.An attempt was also made to find the level of awareness of the respondents about the hazards of e-waste. The Filipino population largely stores three electronic gadgets; namely cellular phones, laptops, and personal computers once the models become old and obsolete. The other most popular disposal method is selling the gadgets to junk shops. Very low percentage of people actually recycled their products. Sixty-nine percent of the respondents did admit that they were actually concerned about the impact of improper disposal of e-waste on human health and environment.Â Read More

Factors that could possibly affect science performance were family structure and parental involvement. This study assessed the science performance of three hundred and one Grade 7 students of Samar National School in relation to their family structure and perceived parental involvement of their father, mother and guardian. In attaining the goal of the study, a survey using a self-made questionnaire was used in gathering data. The data revealed that student respondents’ profile has nothing to do with their science performance, on the other hand, their type of family, head of the family, perceived parental involvement of their mother in school related activities significantly affects their science performance.

A process is defined as a series of actions or steps taken in order to achieve a particular end. Currently, there are a wide range of studies involving different types of processes ranging from engineering, business, biology, to information theory. We are interested in a new type of process study, labelled as Process Based Strategy Model. The process specifically looks into the success probability of an n-step process with n independent step probabilities. In our model, there are exactly n steps that lead to the desired goal Xn a success in step i leads to step i + 1 but a failure in it only leads to goal Xi – 1 and thereby, a failure in achieving the end goal Xn.
