The need of a generalised flow curves considering strain (ε), strain rate ( ) and temperature ( T ) is a primary requirement for material modelling related to several conventional and strategic mechanical processing to meet critical and non-critical engineering applications. The realistic coefficients of flow curves need to be obtained for such model. In the present study a modified Johnson–Cook (JC) material model has been proposed with physical significance. Six constants of this model can be obtained through the regression analysis. When compared to the JC model, proposed model is found to be more reliable for Al-2024 alloy.

Aim: The aim of the present experiment was to examine whether waterlogging induced deficiency or excess of elements, is the cause for reduction in cane weight of sugarcane genotypes under waterlogged conditions. Methodology: The experiment was conducted in pots with eleven sugarcane genotypes grown under control and waterlogged conditions. Waterlogging treatment was imposed at 120 days crop age for a period of 60 days. Cane weight and element concentrations were measured at the end of waterlogging. Results: Compared to control, reduction in cane weight of sugarcane genotypes under waterlogging varied from 5.3% (A-46-11) to 32.3% (CoJ 64). Waterlogging caused a significant decrease in leaf N, P, K, S, Zn and Cu concentrations of sugarcane genotypes; the extent of decreases in leaf N and S were more and values for these elements dropped below their reported critical deficiency level for most genotypes. There was a significant inverse correlation between leaf K and S concentration, and reduction in cane weight of sugarcane genotypes, indicating that genotypes with high leaf K and S under waterlogging have relatively less reduction in cane weight. There were significant increase in the leaf Fe, Al, Mn and Na concentrations under waterlogging, however, increase in these elements were not correlated with reduction in cane weight of sugarcane genotypes. Interpretation: The results suggest that deficiencies of N, K and S rather than excess of Fe, Al and Mn is a major cause for reduction in cane weight of sugarcane genotypes under waterlogged condition. The genotypes tolerant to N, K and S deficiencies under waterlogging can be utilized in breeding program for developing sugarcane varieties with improved waterlogging tolerance.

The blood pressure (BP) lowering response to renal denervation (RDN) remains variable with about one-third of patients not responding to ultrasound or radiofrequency RDN. Identification of predictors of the BP response to RDN is needed to optimize patient selection for this therapy. This is a post-hoc analysis of the RADIANCE-HTN SOLO study. BP response to RDN was measured by the change in daytime ambulatory systolic blood pressure (dASBP) at 2 months post procedure. Univariate regression was used initially to assess potential predictors of outcome followed by multivariate regression analysis. In the univariate analysis, predictors of response to RDN were higher baseline daytime ambulatory diastolic blood pressure (dADBP), the use of antihypertensive medications at screening, and presence of orthostatic hypertension (OHTN) whilst the presence of untreated accessory arteries was a negative predictor of response. Multivariate analysis determined that dADBP and use of antihypertensive medications were predictors of response to RDN with a trend for OHTN to predict response. Obese females also appeared to be better responders to RDN in an interaction model. RDN is more effective in patients with elevated baseline dADBP and those with OHTN, suggesting increased peripheral vascular resistance secondary to heightened sympathetic tone. These assessments are easy to perform in clinical setting and may help in phenotyping patients who will respond better to RDN.

Aim : The present investigation was carried out to study root anatomy of sugarcane cultivars (CoLk 94184 and CoJ64) planted under waterlogged condition through Scanning Electron Microscopy (SEM). Methodology : Two sugarcane (Saccharum spp. hybrid) cultivars, CoLk 94184 and CoJ 64 were evaluated for changes in root anatomy in response to waterlogging during 2017-2018. For waterlogging treatment, crop was grown in deep plot which was waterlogged upto a depth of 1 m during active grand growth stage (monsoon season) along with untreated control plot. After three months of waterlogging, the plants were uprooted to study the root morphology and anatomy through SEM. Results : Waterlogged plants showed aerial root formation in both the cultivars but number and mass were higher in CoJ64. Aerenchyma was formed in the cortical region of both control and waterlogging roots but the size was relatively increased in waterlogged. Control Roots Irregular and damaged surface cells with longer root hairs were observed in waterlogging treatment. Waterlogged roots exhibited cell distortion, loss of uniformity in endodermis and pericycle regions and higher number of metaxylem vessels. Interpretation : The study concluded that waterlogging treatment caused structural anomalies and induced anatomical and surface ultra-structural changes in both the cultivars, but the level of deformation was relatively higher in genotype CoJ 64, indicating sensitivity towards waterlogging as compared to cultivar CoLk 94184.

Aim: To determine the effect of severity of Haemonchus contortus infection on performance and economics of raising kids fed on two respective plane of nutrition. Materials and Methods: The feeding trial was conducted for 120 days with non- descript female kids (3-5 months age). The kids were randomly allocated into two dietary treatments having normal protein normal energy (NPNE) and high protein medium energy (HPME) using conventional feedstuffs (crushed maize, ground nut cake, berseem hay and chaffed paddy straw), fortified with mineral mixture (1%), salt (0.5%) and vitamin premix (@ 20g[q.sup.-1] feed), each treatment having three levels of H. contortus infection ([W.sub.0], [W.sub.500] and [W.sub.2000]) in a 2x3 factorial design. The study was undertaken to ascertain the performance and economics of raising kids fed on higher plane of nutrition. Results: The total dry matter intake (DMI: kg) was 41.18, 39.56 and 41.11 in [W.sub.0], [W.sub.500] and [W.sub.2000] in group HPME; whereas in NPNE the DMI was 39.66, 38.03 and 35.95 kg in the respective infection levels. The highest body weight gain was obtained in HPME than NPNE from 1st to 16th week of experiment. The infected kids at NPNE gained at a slower rate as compared to the kids maintained at HPME. The mean percentage of monocytes, lymphocytes and neutrophils fluctuated in different ways throughout the experiment without any significant difference and these cells were not followed any specific trend. However, significantly higher (P<0.05) eosinophils count was recorded in [W.sub.500] and [W.sub.2000] of HPME fed kids as compared to [W.sub.500] and [W.sub.2000] of NPNE fed kids. In the present study the maximum benefit could be obtained by feeding of HPME diet with [W.sub.500] infection as compared to other treatments. Conclusions: The cost of raising kids per kg meat was worked out to be the most economical at high plane of nutrition even with the heavy H. contortus infection.
