Lipid peroxidation and cadmium bioaccumulation in Volema cochlidium snails in Bacoor Bay.
No full textThis study determined whether oxidative stress in snails inhabiting Bacoor Bay is due to its exposure to heavy metal concentrations specifically cadmium. About 30 snails were collected in Bacoor Bay and assessed for cadmium bioaccumulation and lipid peroxidation assay through the malondialdehyde. All snails examined were found to be contaminated with traces of cadmium. Results showed no significant relationship existing between cadmium bioaccumulation and lipid peroxidation. This implies that the cadmium bioaccumulation in the snails does not play an active role in the malondialdehyde production
The effects on rice germination and seedling growth of volcanic soil from Bacolor, Pampanga.
No full textThe eruption of Mt. Pinatubo in 1991 caused drastic changes in the geomorphology and soil of the area. Pampanga is one of the provinces that was greatly affected by the eruption. Agriculture is the major industry in the province, and rice is their principal crop. Since a vast expanse of the area around Mt. Pinatubo was covered by volcanic soil during its 1991 eruption, the lahar-covered areas have not been utilized for agricultural purposes. To determine whether volcanic soil can be used in growing rice, the effects on rice germination and seedling growth of volcanic soil were compared with loam soil. Rice seeds were germinated and planted on volcanic soil and loam soil. The differences in the growth of the rice seedlings were related to the physio-chemical properties of their respective soils. Both setups have the same percent seed germination despite the low moisture content of volcanic soil. Rice seedlings sown in volcanic soil have significantly lower root length. In spite of this, the rice seedlings that were sown in volcanic soil have significantly higher shoot length and number of leaves. There were no significant differences observed in fresh weight, dry weight, and leaf area. The effects of volcanic soil on seed germination and seedling growth are either better or comparable with loam soil. The study has shown that volcanic soil can be an alternative substrate for rice germination and seedling growth
An ecological survey of mollusk species in the intertidal zone of Nagbalayong Beach, Morong, Bataan (2013).
No full textBataan is coastal province in the Philippines. It is connected to several other coastal areas of the country such as the Manila Bay. Morong, one of the municipalities in Bataan, is home to a large variety of flora and fauna however; very few studies have been done on the diversity of the marine life. In this study, a survey was done on the intertidal region of Nagbalayong Beach in Morong to determine the diversity of mollusks in the beach. A 100-meter transect was laid down on the shoreline of the beach to mark the sampling areas. The high, middle and low intertidal zones were sampled using a 1x1 meter quadrat. Thirty-five species of mollusks were identified in the beach. Through the use of various diversity indices, it was found that Nagbalayong Beach has an average diversity value of 1.63 for the high intertidal zone, 1.83 for the mid intertidal zone, 1.95 for the low intertidal zone and 1.523 for the area 20 meters beyond the low intertidal zone based on the Shannon-Wiener index. The most dominant species in the area were Siphonaria javanica from the family Siphonariidae. Horizontal zonation of species was affected by the type of substrate and abundance of marine vegetation while only substrate type and height affects vertical zonation. Ecologically significant species that may be used as indicators of the health of the beach such as, Atrina pectinata, Circe scripta and Angaria delphinus were also found in the intertidal zone
Database Encryption using CryptDB for DentISt: Dental Information System (DentISt) 4.0
No full textDentISt 4.0 is the fourth version of the electronic patient record in UPCD. Compared
to the earlier version, the new one has an additional security feature which
increases database security and con dentiality.
As security in a system is one of the main concerns in converting from paper based
to electronic-based, hence there is a need to increase database security.
CryptDB encrypts all the data in the database and performs query processing as
if the user is querying over unencrypted data. It encrypts each data in database
according to di erent encryption levels based on the query. This makes the system's
data secure from malicious database administrator and adversaries that may
compromise the server. This in turn leads to providing greater con dentiality and
least privilege access to users, which are the standards of Health Insurance Portability
and Accountability Act (HIPAA)
Renewable Energy Act of 2008: assessment and monitoring of the implementation of the law (2008-2013).
No full textThe development of renewable energy sources has been fairly new to why the establishment of markets in the RE sector requires the intervention of the government. In relation, the Philippines in 2008 have passed its policy on the development, commercialization and utilization of renewable energy, otherwise known as the Renewable Energy Act of 2008. The researcher interviewed key-point persons who has great knowledge about renewable energy and the RE Act of 2008. A survey was also conducted in community to learn how the RE development has affected their area and to what extent the law has affected the community. Reports and other data have been gathered to expose to where the law is at today, 5 years in its implementation. The data has showed the law been effective in enhancing development but lack of efficiency on the implementation. Issues with the government have been recognized to affect the implementation of the law. To which the research concludes three things; The Renewable Energy Act of 2008, otherwise known as R.A. 9513, has been concluded to be effectivity on its implementation but simultaneously having inefficiencies in the implementation process. And finally the law has been concluded to be a policy favouring the private sector taking out in consideration the public’s interest especially when it comes in answering to social issues. The researcher recommends further research should be conducted the better the progress in the development of renewable energy sources, measure should be done to ensure accountability and transparency with the procedures and transactions of the implementation of the law and finally, the creation and passage of a policy complementing the law to which social issues could now be answered
Physic nut (Jatropha curcas) seed cake extract downregulates heat shock protein 70 expression in zebrafish (Danio rerio) liver.
No full textThe use of Jatropha curcas in biodiesel production is one of the emerging alternative sources of renewable energy. However, the extraction process leaves a seed cake waste and the lack of disposal protocols poses serious threat to ecosystems. This study aims to determine the toxicity of the seed cake extract to zebrafish through the analysis of heat shock protein 70 expression. The median lethal concentration (LC) was first determined through an acute toxicity test coupled with probit analysis. For the HSP70 induction test, fishes were subjected to a nonexposed setup and sub-lethal concentration setups of detoxified, washed, and untreated seed cake. RNA was isolated and reverse transcribed followed by polymerase chain reaction and gel profiling. Results indicate an LC50 of 0.172% (w/v) or 1.72 g/L. The heat shock induction test showed a significant downregulation of HSP70 expression in fishes exposed to washed and untreated setups. This under-expression may be attributed to phytochemicals such as lectins which have been noted to interact with HSP70. Furthermore, mRNA levels in the detoxified setup have no significant difference with the non-exposed setup, possibly indicating a successful inactivation of toxic phytochemicals in the seed cake. Moreover, the present study shows that downregulation of HSP70 is also an indicator of stress, and low HSP70 levels may lead to decreased resistance to stress-inducing agents
Assessment of Aeromonas contamination of shellfish sold in public markets of Bacoor, Cavite.
No full textAeromonas spp. is an emerging foodborne pathogen associated in fish and other seafood. The assessment of Aeromonas spp. From oysters and mussels sold for human consumption in public markets is of public health concern as it may bring about morbidities to people who are exposed to it. This study aimed to assess the shellfish sold in a public market in Bacoor, Cavite for the possible Aeromonas spp. contamination. A total of ten pooled samples of oysters and mussels obtained from Bacoor bay, Cavite was assessed for Aeromonas contamination. Colonial morphological and biochemical characterization were done to isolate the Aeromonas sp. Organisms. Three out of the ten samples tested were suspected for Aeromonas spp. contamination
A critical analysis on the socio-economic effects of Philippine-China trade and foreign direct investment
No full textEvery country has its different advantages and specializations. Certain ingredients add up to this variation such as geographical location, historical events, culture, society, etc. Due to their uniqueness and distinction, certain products are only available to be produced efficiently in a certain place. With the advent of globalization, these products can now be within reach by different countries that are in need of said commodities. These do not only pertain to consumer goods such as food, beverages, and clothing, but also to labor forces that are cheap as well. In the case of the Philippines and China, different factors contribute to the continuous exchange of goods. These are land, or the raw materials that the two posses, labor, and the bamboo network, which is the a network of close-knit Chinese entrepreneurs with large corporate empires in southeast Asia that contribute mostly to the advancement of China’s economy. With the opening up of China’s market, it has now become one of the global superpowers that dominate the international trade relations. The Philippines, being one of its long-time partner, should maintain its authority over its territories, and resources. It should uphold national sovereignty and assert its rights for the benefit and welfare not just of the few elites, but also for the masses, which contribute the majority of the population in the Philippines
An evaluation of CHD’s alternative health care system at the community level.
No full textThis paper will serve as an evaluation of the Council for Health and Development’s forty-year performance as of year 2013. It will serve as an unbiased critique so as to aid in the improvement of their services. In order to do so, the researcher will interview the head of the Advocacy and Research Department, Ms. Kat Berza, as she is most informed of the programs and mobilizations that the council participates in. After the data gathering, the researcher found out that the council has been well-adjusted to social changes and technological innovations that the country has went through. They also consult with credible research institutions such as the IBON FOUNDATION to supplement their theoretical foundations. They also offer non-band aid solutions but rather grassroots and long-term benefitial answers to problems that communities face. They, however, just like any other organization are still flawed. The council still needs to improve on its information dissemination mechanism, the level of skills of their Community Based health Programs and staff, Luzon-centeredness, and their social impact management. It is then recommended by the researcher that the council focus on these flaws, improve on their strengths, and if possible, create a self-evaluating mechanism so as they further improve as the years go by, letting them adapt well to the constant flux of society
NIH-TRB Research Monitoring and Tracking Information System (ReMTIS 2.0)
No full textThe creation of the National Institutes of Health (NIH) under the UP Manila System was a boost to the University’s existing research infrastructure. Research Monitoring and Tracking Information System (ReMTIS 2.0) enables research facilitators of NIH to manage health research records and ensure secured, convenient and systematic flow of information with emphasis on the Technical Review Board of NIH. Protocol information is stored in a single database. This reduces the problems of redundancy and inconsistencies using a paper-based system and OpenOffice applications. It also allows users to view protocol information depending on their role. This allows not only sharing but also distinction and confidentiality among the records. It also serves as an electronic tracking system of research projects with the use of a notification system and a calendar system that help prevent time management issues. The system also allows administrative report generation
