The rice variety,Co 51,was specifically selected for the development of white polished rice,brown rice(BR),and germinated brown rice(GBR).GBR rendered significant increases in nutrients,including dietary fiber,resistant starch,total antioxidant activity,γ-amino butyric acid(GABA),γ-oryzanol,and ferulic acid content compared with *** cooked GBR and white polished rice(120 g)were served with a known quantity of pulses and vegetables without affecting the physical activities of selected groups and the total experimentation period spanned 120 *** the end of the study period,the experimental group consuming GBR showed a significant decrease in fasting blood glucose(FBG),average glycated hemoglobin(HbA1c),total cholesterol(TC),triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C),compared with the group taking white polished *** findings suggest that owing to GBR’s better nutrient composition and bioactive functional ingredients,the long-term consumption of GBR would effectively lower the risk of prediabetes related to FBG,HbA1c,and TG.

Elie Metchnikoff’s lecture illustrated that‘men were free from microbes at birth and within tenth and seventeenth hour of birth the surface of skin,mucous membranes,respiratory passages,and more abundantly the digestive organs became peopled with microbes derived from the air or water’.1 It is interesting to note that the revised ratio of human cells to the number of bacteria in the body is 1:1,which is further tipped towards the human cell mass following each defecation.

In the recent years, the phase field method for simulating fracture problems has received considerable attention. This is due to the salient features of the method: 1) it can be incorporated into any conventional finite element software;2) has a scalar damage variable is used to represent the discontinuous surface implicitly and 3) the crack initiation and subsequent propagation and branching are treated with less complexity. Within this framework, the linear momentum equations are coupled with the diffusion type equation, which describes the evolution of the damage variable. The coupled nonlinear system of partial differential equations are solved in a 'staggered? approach. The present work discusses the implementation of the phase field method for brittle fracture within the open-source finite element software, FEniCS. The FEniCS provides a framework for the automated solutions of the partial differential equations. The details of the implementation which forms the core of the analysis are presented. The implementation is validated by solving a few benchmark problems and comparing the results with the open literature.

Synchrophasor devices guarantee situation awareness for real-time monitoring and operational visibility of smart grid. With their widespread implementation,significant challenges have emerged, especially in communication, data quality and cybersecurity. The existing literature treats these challenges as separate problems,when in reality, they have a complex interplay. This paper conducts a comprehensive review of quality and cybersecurity challenges for synchrophasors, and identifies the interdependencies between them. It also summarizes different methods used to evaluate the dependency and surveys how quality checking methods can be used to detect potential cyberattacks.
