Item The role of women rebel returnees in the armed conflict and transformation politics in Leon, IloiloApatan, Mildred V. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03)The study focuses on the role of the women rebel returnees in the armed conflict and transformative politics in Leon, Iloilo. Descriptive in nature, it pioneers in the study of women rebel returnees in the region. It has the following objectives: to determine the reasons of the women rebel returnees for joining the insurgency movement, to determine the nature of their political participation and role in the ai med conflict, to identify the reasons which brought them back into the mainstream of society, and to describe the role they played in transformative politics. The method used in gathering the data was personal interview with an interview guide. Also, a questionnaire on their socio- demographic profile was provided. The study found out that, in general, the women rebel returnees joined the insurgency movement for social reasons such as influence of those who were already members of the movement. Their role inside die movement was mostly reproductive in nature, that is, works that deals mostly with or involves their comrades and the movement. Their reasons for leaving the movement were also socially motivated. Their participation in transformative politics is also reproductive in nature and that their positions in various organizations and institutions belong to a relatively upper level. Their problems are mostly financial and could be addressed by giving them more projects, opportunities, and network with other women's organizations.Item Effects of high and low protein diets on the gut evacuation rate of Tilapia niloticaAndrada, Bryan Andrew S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-03)Gut evacuation rate of young Nile tilapia, Tilapia nilotica fed commercial pelleted diets containing high or low protein diet were determined in the laboratory. The decline in gut fullness of the fish with time was examined at low and high protein diets. Two mathematical models were used to express the decline in gut fullness of the fish with time. Fish fed the low protein diet followed more closely the linear model while those fed the high protein diet followed the logarithmic model. The level of protein resulted in different gut evacuation rates (GER), expressed as coefficients b of the gut fullnesstime curve. GER values were higher in either linear or logarithmic models for fish fed low protein diet than for those fed high protein diet.Item Diel feeding patterns of angelwing clam Pholas (Monothyra) orientales (Gmelin, 1970)Alojepan, Marbe Joy L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-04)Filtration rate of Pholas orientalis measured using the indirect suspension deletion method and monitored by direct algal cell counts. Phytoplankton Isochrysis galbana was used as food at an algal cell concentration of 2.5 x 103 cells ml ”'. Biological rhythms have been demonstrated in all animals and plants except bacteria. They control rhythmic patterns in behavior and physiology of a living organism. Biological rhythms, or oscillations, have a “period” that is measured from one arbitrary point or phase of the rhythm to the next occurrence of that phase. They are best demonstrated in a 24 h cycle or circadian cycle. There is a widely varying feeding activity in the 24h cycle of P. orientalis observed at a constant temperature of 27$C and hydrogen ion concentration of 35%o Like any other bivalves, P. orientalis has defined feeding periods equivalent to food uptake at 2400h-0300h. Such observation could be supported by a previous study by Corda stating that optimal feeding was obtained at total darkness. Periods of digestion occur shortly after the periods of feeding. P. orientalis when actively feeding were observed to have extended siphons, larger valve openings, and an inclination of 45. One primary external stimulus that affected filtration rate was the amount of light present. Biorhythms provide temporal information, such as the time of day or season of the year, which facilitates adaptation of the organism to internal or external environments.Item An assessment of the fishery ordinances of the different coastal municipalities in the Province of Iloilo, 1992-1998Almero, Flora B.; Gerona, Ma. Leda G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-12)This research project is an assessment of the fishery ordinances of the different coastal municipalities in the Province of Iloilo. The study covers the fourteen (14) coastal municipalities of the Province namely; the Municipality of Anilao, Banate, Barotac Nuevo, Barotac Viejo, Batad, Carles, Concepcion, Dumangas, Estancia, Miag- ao, Oton, San Dionisio, San Joaquin and Tigbauan. The primary data were taken from the various municipal fishery ordinances of the different coastal municipalities under study, and the national fishery policies (RA 7160, PD 704, RA 8550). The researchers also employed field interviews with selected fisherfolk leaders as a source of first hand information concerning the recent situation of the fishery industry in their respective municipalities. It was found that: (1) the fishery industry in the Province of Iloilo is facing problems on overexploitation, overfishing, pollution, and habitat destruction; (2) the primary concern of the over-all policy mosaic for the fishery industry is the rehabilitation and protection of the coastal environment, the limitation of access to fishery resources comes as the secondary concern, while the protection of the rights of municipal fisherfolk appears in a very limited number of promulgations only; (3) generally the provisions in the over-all policy mosaic is consistent and complimentary, both vis-a-vis the national fishery policies and within their respective municipal fishery ordinances where the provisions belongs. Assessing the municipal fishery ordinances of the different coastal municipalities in the Province of Iloilo, it was found that the goal of the over-all policy mosaic is the promotion of sustainable development for the fishery industry so as to achieve food security in terms of fish.Item A taxonomic survey of epiphytes on Enhalus acoroides in Ali Cove, Taklong Island, Nueva Valencia, GuimarasAlojado, Ezra Nelson E. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-06)Epiphytes were collected from the blades of the seagrass Enhalus acoroides which were harvested from Ali Cove, Taklong Island, Guimaras. 20 epiphytic algae were identified with the aid of taxonomic keys. Of these, five belong to the Cyanophyceae, two to the Chlorophyceae, one to the Phaeophyceae, eight to the Rhodophyceae and four to the Bacillariophyceae. Thirteen specimens were identified to the species level and seven to the genus level only. Measurements of temperature, salinity and pH were taken at the study site during the collectionItem A preliminary study on the effect of neem (Azadirachta indica) seed extract on the reproductive potential of the female Friutfly (Drosophila melanogaster)Altea, Armee H. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-04)Eqqs, first instar larvae, and third instar larvae of fruit flies (D. melanogaster), were treated with 0%, 10%, and 15% neem seed extract. This resulted in reduced number of adults that emerged from treated embryos and larvae. Females following treatment crossed with untreated males have reduced number of progeny compared with control (untreated) females. Treatment of extract at three stages of development indicated that fertilized eggs were most affected by the extract. Females derived from treated eggs were sterile. The number of progeny produced by females treated during first instar stage were considerably reduced compared to controls. On the other hand, the number of progeny produced by females treated during third instar stage was not significantly different from controls. The results suggest that neem seed extract has active components which can reduce the reproductive potential of female fruit flies exposed to the chemicals particularly at the early stages of development.Item Age and sex of Miagao public market vendors as determining factors in role preferences on women as portrayed in comic booksAlvarez, Lee T.; Cababa-an, Glenn C.; Diaz, Gladys C. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 1996-03)This research is about age and sex as determining factors in role preferences of the respondents on women as portrayed in comic books. The researchers have chosen the market vendors of Miagao as respondents in this particular study for the reason that most market vendors, if not all, do read comic books. The researchers were able to gather a total of seventy [70] respondents. Of the seventy [70] respondents, thirty-two [32] or forty-six percent [46%] are males and thirty-eight [38] or fifty-four percent [54%] are females. In this study, it was found out that most of the respondents read comic books with the love theme and only a few read comic books having mixed themes. The researchers have also discovered that both the male and female respondents agree that women in most cases were presented in a more conservative rather than in the liberal light. Chi-square statistical tool with .05 level of significance was used and it resulted to the finding that there is no significant relationship between the age, the sex and the preference of the respondents with regards to the roles of women a® portrayed in our local comic books.Item Effect of Physico-chemical parameters of rearing waters on survival rates of larvae and post larvae of Penaeus monodon in two hatchery systemsAlindong, Ray Lauron (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1995-03)Physico-chemical parameters such as temperature, pH, salinity, and D.O. of the small-scale and large-scale hatchery system were monitored daily for a duration of two months. The relationship between the physico-chemical parameters and the survival of the different larval and post-larval stages between the two hatchery systems was then determined. Results showed that the physico-chemical parameters obtained from the small-scale hatchery system were favorable to the survival of the larval stages of the prawn. However, the physico—chemical parameters obtained from the large-scale hatchery system were more suitable for the growth of the post-larval stages.Item A preliminary investigation of the antibacterial activity of the alkaloidal constituent of Hyptis suaveolens Poit (Family Labiatae)Alcayde, Glenn G. (Division of Physical Sciences & Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 1999-03)This study determined the effectiveness of the alkaloidal constituent on the leaves ofHyptis suaveolens against the four bacteria namely S. aureus, B. subtil is E. coli, and P. aeruginosa, and two fungi namely C. albicans and S. cerevisae. The alkaloidal constituent was first detected using the Culvenor-Fitzgerald method. It was then separated in the form of an alkaloidal residue. The residue was separated further using column chromatography. This process resulted in three fraction isolates.These three fraction isolates were purified and determined their physical properties. Finally, each fraction isolate was prepared into three concentrations, 100%, 50%, and 25%. The isolates of three concentrations were then tested on six microorganisms and growth of inhibition was measured. Results showed that the three fraction isolates in three different concentrations exhibited no antibacterial and antifungal effectItem A historical analysis of Pintado (Euphorbia heterophylla)Alcarde, Annabelle Z.
