"Socioeconomic Conditions of the Settlers in Nam Ngum Project"
The study was undertaken mainly to identify the socioeconomic conditions of the settlers and the factors associated with their problems. Subjects of the study were 100 farm households in three sample villages in the Nam Ngum settlement area...

The study sought to determine the extent of protein loss during rice milling and the effects of mill type and settings on such loss. Rice varieties used in the experiment were IR 20, IR 26 (both medium-bold subtype), IR 30 and C4-63 (both...

This study was conducted to determine the effect of temperature, reaction time, and type and concentration of acid on the hydrolysis of coconut and soybean meals. Release of free amino nitrogen from peptide bonds was used as a measure of... Read more.MS (University of the Philippines Los Baños)"Supply Response of Corn to Price in the Philippines, 1957-1974"
The study involved a test of major hypothesis about the economic behavior of Philippine corn producers. Supply response functions were estimated to test whether corn producers respond rationally, in terms of quantity produced and area planted, to...

The photosynthetic rate water hyacinth plants was measured with the use of URAS infra red gas analyzer at constant CO2 concentration of 400 ppm, 25°C and 70% relative humidity. The photosynthetic rate was found to vary from 1.61 to 15.52 mg...

The effect of shower frequency on the reproductive performance and physiological responses was investigated in 32 seven-month-old crossbred gilts. The animals were divided into four treatment groups composed of no shower, shower once, shower...

The study sought to determine the effect of hulling, cooking time and fermentation time on the quality of soymilk. Results showed that total protein content, amino acid nitrogen viscosity, pH of soymilk before and after processing and...
