Fourier transform infrared (FTIR) spectroscopy was mostly used in both pharmacopeia and literature studies to determine the assay of simethicone (SMT) in pharmaceuticals. It should be noted that HPLC is used less frequently. As an alternative to the mentioned methods a new, simple, fast, easy-to-apply and very cheap gravimetric method was developed and validated according to ICH guidance entitled Q2B Validation of Analytical Procedures: Methodology for the quantification analysis of simethicone in different pharmaceutical forms. For the simethicone suspension product provided to alleviate too much gas in the gastrointestinal tract, the simethicone amount was determined both by the validated gravimetric method and by the FTIR method defined in the USP and BP monographs, and the results were within the acceptance criteria. It is emphasized that there is no significant difference between the results of gravimetric and FTIR methods according to the calculated F- and t-test results.

The objective of this research is to know the comparison of Superjohn varieties and varieties of Granola L in Pinasungkulan Utara Village, Modoinding District. The location of the study was determined purposively (purposive sampling), the determination of the number of samples taken by census (Saturated Sampling) for farmers varieties Granola L as much as 20 farmers and 20 farmers Superjohn varieties taken simple random (Simple Random Sampling). The method of analysis used in this research is the analysis of farm income and komaparatif analysis by using t-test two samples Independent Sample T-test. The results showed that the average income of farmers Superjohn varieties is Rp.70.062.947,00 lower than the average income obtained by farmers varieties Granola L Rp.87.029.058,00. It can be seen that the average income difference between the two varieties is Rp.16.960.111,00. Based on statistical test results with MINITAB Program, the calculation of income per hectare obtained significant value of P-Value of 0.01 at α 5% that is 0,01 < 0,05. This means that H0 is rejected and H1 is tested for the fact that there is a significant difference between Superjohn varieties potato production income and Granola L varieties.

This study was conducted to determine the gossypol content in Bt cottonseed (Seeni-1) oil by using Fourier Transform Infrared (FTIR) spectroscopy with an Attenuated Total Reflectance (ATR) element. The wavelengths used were selected by spiking refined, bleached deodorized palm oil (RBDPO) to gossypol concentrations of 0-5% and noting the regions of maximal absorbance. Absorbance values of the wavelength regions 3700-2400 & 1900-750 cm-1 and a partial least squares (PLS) method were used to derive calibration models for Hamid cottonseed oil, Seeni-1 cottonseed oil, and gossypol-spiked RBDPO. The coefficients of determination (R2) for the calibration models were computed for the FTIR spectroscopy results against those found by using the wet chemical method AOCS method Ba 8�78. The R2 was 0.8916, 0.9581, and 0.9374 for Hamid cottonseed oil, Seeni-1 cottonseed oil, and gossypol-spiked RBDPO, respectively. The standard error (SE) of the calibration was 0.053, 0.078, and 0.062, respectively. The calibration models were validated using the cross-validation technique within the same set of oil samples. The results of FTIR spectroscopy as a useful technique determining gossypol content in crude cottonseed oil showed that there is a significant difference (p <0.05) in the amount of gossypol content in Hamid and Bt Seeni-1 cottonseed oils.

The paper examines the existence, if any, of differences in gross margin between rural and urban areas in Delta State, Nigeria. Data were collected from all 275 poultry farmers registered with the Delta State Ministry of Agriculture, Livestock Department. The null hypotheses was that there is no significant difference in poultry farm gross margin between locations in terms rural and urban areas; managers with formal education in agriculture and managers who have no formal education in agriculture; and managers who have and who do not have prior experience in poultry business. Data were collected from all 275 poultry farmers registered with the State Ministry Agriculture using copies of a structured questionnaire and were analyzed using frequency counts, means and T-test. Amongst the findings were: Majority of poultry business operators have low level formal education in disciplines not related to agriculture; there was a significant difference in the mean number of years of schooling and courses studied between rural and urban areas but that there was no significant difference in number of years of prior experience. The T-test results failed to reject the three null hypotheses. The study concluded that indeed elements of opportunity may vary from place to place but the ability to exploit the benefits may moderate or accentuate performance. Entrepreneurial capacity building was recommended for poultry business operators’ state wide.

The study was intended to examine the effect of mental health on old people. Aim: The aim was to estimate the prevalence of mental health in old people and to determine the association of mental health with types of family and gender. Sample: The sample consists of 120 old people from different old age home and family in Rajkot district area. The sample was selected from randomly. Design: 2*2research design was used the present study. Tools: Mental Health was measured through a questionnaire ‘Mental Health Inventory’was used. Test developed by Bhatt D & Gida G. in (1992).The data was analyzed by the t test. Results: There will be no significant difference between Gender and Types of Area in relation to their mental health. Conclusions: Our study demonstrates a higher prevalence of mental health in old people.

This study aims to find out the comparison between the performance of Islamic Banks including financial performances such as the ratio of ROA, ROE, FDR and CAR as wells economic and social performance such as MMR ratio before and after the determination of fatwa regarding the prohibition against bank interest. Quantitative approach and independent sample t-test has been used in this study. The data is a secondary data which was obtained by collecting the annual financial reports. The result of the independent sample t-test shows that there are significant differences between the performance of the Islamic banks before and after the fatwa on the ratio of ROE, FDR and MMR. Whereas on the ratio of ROA and CAR have no significant difference before and after the fatwa.

Abstract The official AOAC manual Kjeldahl methods for determining crude protein in animal feeds have several disadvantages. For the HgO catalyst method, there are environmental concerns and a lengthy digestion. For the CuS04 catalyst method, the digestion period is shorter, but still 90 min. A different catalyst combination, CuS04-Ti02, makes 40 min digestion feasible. Comparison of these catalysts on a group of representative feeds resulted in a mean difference, Cu-Ti minus HgO, of 0.034% protein. Standard deviation of the differences was 0.36. A Student’s t-test showed no significant difference. The method will be collaboratively studied.
