Using a combined lagged-group and cross-panel design we assessed the effectiveness of a sequence of four different instructional components: observation and group reflection on a mastery model, direct (declarative) instruction, peer feedback and solo practice. Cumulative effects on written product and writing process were assessed at baseline and after each component. Findings supported the effectiveness of strategy-focused intervention: All three groups showed gains, relative to controls, in the quality of their written products assessed by both holistic and text-analytic measures, and a more structured and goal-focused planning processes. These effects were associated almost exclusively with the modelling and reflection component. Improved performance was sustained through other instructional components but there was no strong evidence that they provided additional benefit. This finding was replicated in all three groups, and across two different text-types.

Heavy metals has been one of the feared toxins today because of its psychological andphysiological effect. This research was designed to determine the heavy metals present inCalbayog and Antiao River and to obtain the concentration of the present heavy metals. Thisstudy was conducted based on instrumental analysis which has been accepted in determiningthe presence and concentration of heavy metals. The environmental parameters weredetermined first. pH of Antiao and Calbayog River is 7.53 and 7.23, respectively, thus they areslightly basic. Salinity of Antiao and Calbayog is 30 ppt and 34 ppt respectively, which are high.Turbidity of Antiao River and Calbayog are 0.94 m and 0.81 m, respectively, therefore they arequite turbid. Samples are tested for the presence of heavy metal, Mercury (Hg) is present in thetwo rivers. Cadmium (Cd) is present in the sediment of Antiao River. Concentrations of Cd andHg was analyzed using AAS, the concentration of the two are below detection limit. The resultsimplied that the levels of heavy metals found in selected rivers are low, though this does notmean that the threat of these metals is absent. Bioaccumulation in living organisms could posea greater threat.

Pain has always been a cause of concern to humans. People often searched for remedy from plants because of the many documented side effects of commercial medicines. This study was conducted to determine the analgesic efficacy of the root decoction of Salacia korthalsiana Miq (Polipog) found in Mondragon Northern Samar. Acetic acid-induced writhing method was used to test the analgesic activity of polipog. Writhing test is a chemical method used to induce pain of peripheral origin by injection of irritant (ex. acetic acid). The manifestations of abdominal writhing in mice were described as an arching of back, extension of hind limbs and contraction of abdominal musculature. Analgesic activity of the test compound is inferred from decrease in the frequency of writhing.  From the results obtained, polipog is comparable to the commercially available drugs in terms of analgesic efficacy.

Phytochemical profiling focuses on the determination of the secondary metabolite present on a sample. Aims: In this research, a phytochemical profiling was done in Saribus rotundifolius (Anahaw) leaves and fruit crude extracts. Methodology: This study determines the secondary metabolites; alkaloid, tannin, flavonoid, cardiac glycoside, saponin, and terpenoid. The samples were cut into pieces and was submerged in an ethanol solution for the extract of crude extract and undergo a rotary evaporator for the separation of the ethanol solvent. Results: The finding showed that the anahaw leaves and fruit crude extract contains secondary metabolites present in both leaves and fruit crude extracts, that can be used in pharmaceutical and drug development, this includes an anti-microbial potential.
