(Bull. Chem. Soc. Jpn. 2020(93): 1164–1170.)Effects of the alteration of the glomerular barrier morphology and the hemodynamic factors associated with diabetic nephropathy on the first step of renal urine formation is investigated through a mathematical model where the glomerular capillary is assumed to be a network of cylinders with complex multi-layered walls separating blood plasma and primary urine. The filtrated excess fluid across the capillary wall causes the protein and test solutes concentration to increase as a function of the distance from the capillary afferent end. The average sieving coefficient, the ratio between the test solute concentration in the primary urine and that in the blood plasma in the lumen, is obtained from the steady-state finite element solution of the convection-diffusion equation and is compared to the sieving coefficient of ficolls from an in vivo study performed in healthy and early diabetic Wistar rats.This study aimed to investigate the effectiveness of microbially induced carbonate precipitation (MICP) process for repairing plastic shrinkage cracks. Self-healing composites were prepared by mixing bacterial spores with nutrients. Bacillus sphaericus spores were added at 0%, 0.5% and 1% by weight of cement. The nutrients used were yeast extract, urea, and calcium nitrate tetrahydrate (Ca(NO3)2・4H2O). The results showed that the MICP process was successful in healing the plastic shrinkage cracking when 1% bacterial spore was incorporated. The XRD patterns showed that the CaCO3 crystals favored the formation of calcite phase. However, the 28-day compressive strength decreases with the inclusion of nutrients used to growth the bacteria.Mango is one of the most important economic fruit in Thailand. However, mango is susceptible to anthracnose disease causing quality loss and reduced market value. This research developed a rapid, nondestructive and chemical-free method based on hyperspectral imaging spectroscopy (HIS) coupled with chemometrics and pseudo-color image processing for early detection of anthracnose caused by Colletotrichum gloeosporioides on mango. The HIS system covering the wavelength range of 400-1000 nm was used to acquire the hypercube data of the samples. The HIS integrated with chemometrics including principal component analysis (PCA) and discriminant factor analysis (DFA) was able to detect the infection at the early stage of disease symptoms and classify different levels of infection. Anthracnose symptom distribution maps were constructed using pseudo-color image processing to facilitate visualization of the anthracnose symptom. The HIS coupled with chemometrics and pseuso-color image processing can be used to rapidly identify and classify samples with anthracnose infection.
