esearch. This study aimed to identify and evaluate the effects of different dietary manipulations on the physiology, biochemistry, organ Coefficient and histopathology of the rats. The rats were given different time intervals on feeding for intermittent fasting and different calorie feeds for calorie restriction. The combined intermittent fasting and calorie restriction observed the fasting interval with different calorie preparations. The weight, temperature, blood chemistry, organ coefficient and histopathology were monitored for four weeks. On the physiological parameters, results showed a significant decrease in the weight of the rats and changes in their body temperature. Biochemically, there was a significant decrease in the blood glucose level, LDL level, Triglyceride level and an increase in HDL level. On the organ coefficient or ratio of organ to body weight, there were neither abnormalities nor significant changes observed. For the histopathological aspect, there were no Histopathological remarkable lesions observed on all the organs coming from the different treatments. These findings indicate additional prospect of the possible practice of combining intermittent fasting with calorie restriction in dieting. In this way, enhanced knowledge and new biological application may be achieved, which can be a driving force in improving human health and longevity in the coming years.

"Evaluation of Dried Banana Fiber Reinforced Paving Bricks" Adviser: Engr. Alan N. Morales This paper was able to evaluate the effectiveness of Dried Banana Fiber (DBF) as a reinforcement and substitute for cement in paving bricks in terms of weight. The statistical method used to analyze the data was Analysis of Variance. In terms of Mechanical Property, the bricks with 2% DBF was the strongest among the treatments as it had a mean compressive strength of 6.34 MPa in 7 days of curing, 7.31 MPa in 14 days of curing, and 9.86 MPa in 28 days of curing. Comparatively, the Control had the highest mean compressive strength of 10.94 MPa in 28 days of curing. Based on the Water Absorption Test, most of the block with Dried Banana Fiber absorbed more water than the control. Paving bricks with 4% dried banana fiber got the highest mean water absorption. The researcher concluded that dried banana fiber created voids within the paving bricks that allows the water to pass thru. In the drop test, the best treatment showed no signs of cracks or breaks after being dropped | meter above the ground. Just some part of its edge got chipped away because of the impact. Comparing the cost between Dried Banana Fiber Reinforced Paving Bricks and Commercial Paving Bricks. DBFRPB was more economical having a cost of Php 5.82 for a paving brick with 2% DBF, Php 5.81 for a paving brick with 3% DBF and Php 5.79 for a paving brick with 4°% DBF.
