  • The maintenance of intestinal health is complex and relies on a delicate balance between the diet, the normal microflora and mucosa, including the digestive epithelium and overlying mucus layer. The colorectal mucosa is protected by a visco-elastic mucus gel formed by high molecular mass glycoproteins referred to as mucins. Abnormality of mucin have been identified with colorectal disease. Constipation increases with age, and is more common among women than men in all age groups, e.g. 10% of men and 20% of women in the USA. The aim of the present study was conducted to investigate that the effects of formulation KTG075 from edible plants on intestinal function on mucus secretion, were examined by loperamide-induced constipation method using Sprague Dawley male rats. Epithelial cells of colonic crypt contained more mucus in the KTG075 group compared with those of the control group and the thickness of the mucus layer stained with alcian blue was significantly thicker in KTG075 treated rats compared with in control rats. Mucus production of epithelial cells of crypt and mucus contents at fecal and mucosa surfaces were reduced by loperamide-induced constipation. These results indicates that a poly herbal formulation KTG075 accelerates evacuation and activated intestines.

  • Theoretical analysis for the thermal performance on the low-cost trickle collector, which is easy to manufacture and construct, has been performed. The results were in reasonably good agreement with those of the experiments. They have been applicable to predict long-term thermal performance on the low-cost solar collecting system. The dialogue type of computer program has been written based on the f-chart method and it can be used for designing a these collecting system, and investigating its economic feasibility.

  • Compressive strength in concrete increases with time. Regression analysis with time is conventionally performed for strength evaluation and prediction. In this study, hydrate amount is assumed as a function of hydration rate and porosity, and modeling on compressive strength is carried out considering decreasing porosity with time, which does not need the regression analysis with time. For twenty one mix proportions of HPC (High Performance Concrete), DUCOM (FE program) which can simulate the behavior in early aged concrete is utilized, and porosity from each mix proportions is obtained with time. For HPC with OPC (Ordinary Portland Cement) concrete, modeling on compressive strength is performed considering hydration rate, unit content of cement, and porosity with time. For HPC with mineral admixtures, a long-term parameter which can handle long-term strength development is additionally considered. From the comparison with the previous test results, the applicability of the proposed model is verified.
