The sprayed chemicals on tea leaves disappear over a period of time by the influence of rainfall elution, evaporation, growth dilution, and photodegradation. Influence of plant growth on the four fungicides (hexaconazole, propiconazole, tridemorph, and c) was studied to know the constructive loss of fungicides. The study shows that residues of fungicides sprayed on tea shoots got diluted by the growing process. The expansion of a leaf took 8 to 11 d and more than 50% of the fungicide residues were cleaned out during this leaf expansion period. Under south Indian agroclimatic condition, the fungicides are sprayed at an interval of 10 d, so it is safe that the tea is harvested on the 10th day of the application of fungicides.

Type 2 diabetes mellitus (T2DM) has become a global epidemic, where increasing urbanization encourages sedentary lifestyles. Persistent physical inactivity can lead to T2DM and increase the risk of T2DM in the general population. Therefore, the aim of this study was to explore the knowledge, attitudes, and practices (KAP) regarding exercise amongst T2DM and non-diabetic (ND) staff at a tertiary institution in KwaZulu Natal South Africa.

This work investigates the adhesive property of Soy Protein Isolate(SPI)polymer solution by studying mechanical properties of composites formed using waste wood granules and SPI solutions. To improve the adhesive strength of SPI solution, Carboxymethyl Cellulose Sodium(NaCMC)was mixed (in the weight ratios of 9:1 and 8:2) due to its strong gel formation capabilities. The adhesive performance of these composites was further investigated in the presence and absence of non-toxic additives, including sorbitol (SOR) and stearic acid (SA).

Gestational Weight Gain (GWG) modulates pregnancy outcomes and long-term offspring metabolic health. The 2009 Institute of Medicine (IOM) GWG recommendations have largely been validated in Caucasian and mono-ethnic East Asian cohorts. Asians are at higher metabolic risk at a lower body mass index (BMI), and this has prompted the World Health Organization (WHO) to identify lower BMI cut-offs for risk evaluation amongst Asians.
