Cost and Return Analysis of Kinnow Mandarin (Citrus reticulata Blanco) with the Foliar Application of Potassium and Plant Growth Regulators

Kinnow mandarin (Citrus reticulata Blanco) belongs to family Rutaceae. In India, Kinnow is being grown in Punjab, Rajasthan, Haryana, Himachal Pradesh, Jammu & Kashmir and Uttar Pradesh. To evaluate the most profitable treatment, economic analysis of treatments was worked out in terms of net return and Cost benefit ratio (C: B) ratio. The cost incurred on basin preparation per tree (` 40), Cost of FYM per tree (` 60), Cost of Urea per tree (` 3), Cost of DAP per tree (` 12.60), Cost of MOP per tree (` 30) and miscellaneous charges (Irrigation, plant protection measures, harvesting of fruits etc.) per tree (` 150) was found to be same in all the treatments. The cost incurred on the preparation of different solutions of potassium nitrate (KNO3) in various treatments was found to be ` 18.60 for 3.0 % KNO3 per tree followed by ` 12.40 for 2.0 % KNO3 and ` 6.20 for 1.0 % KNO3 and in preparation of different solutions of potassium sulphate (K2SO4) it was found to be ` 9.90 for 1.5 % K2SO4 per tree followed by ` 6.60 for 1.0 % K2SO4 and ` 3.30 for 0.5 % K2SO4. In case of preparation of ethrel in different treatments was found to be ` 6.75 for 450 ppm ethrel followed by ` 4.50 for 300 ppm ethrel and ` 2.25 for 150 ppm ethrel and the cost incurred for preparation of 75 ppm GA3 was found to be ` 22.60. It was found that 75 ppm GA3 treatment was best and showed highest net returns per tree ` 916.35. Thus, Kinnow mandarin trees treated with GA3 75 ppm was found to be best treatment combination as evidenced by cost: benefit ratio of 1: 3.8

Rarefied flow past a flat plate at incidence

Results of a numerical study using the direct simulation Monte Carlo (DSMC) method are presented for the transitional flow about a flat plate at 40 deg incidence. The plate has zero thickness and a length of 1.0 m. The flow conditions simulated are those experienced by the Shuttle Orbiter during reentry at 7.5 km/s. The range of freestream conditions are such that the freestream Knudsen number values are between 0.02 and 8.4, i.e., conditions that encompass most of the transitional flow regime. The DSMC simulations show that transitional effects are evident when compared with free molecule results for all cases considered. The calculated results demonstrate clearly the necessity of having a means of identifying the effects of transitional flow when making aerodynamic flight measurements as are currently being made with the Space Shuttle Orbiter vehicles. Previous flight data analyses have relied exclusively on adjustments in the gas-surface interaction models without accounting for the transitional effect which can be comparable in magnitude. The present calculations show that the transitional effect at 175 km would increase the Space Shuttle Orbiter lift-drag ratio by 90 percent over the free molecule value

Severe androgenetic alopecia as a maker of metabolic syndrome in male patients of androgenetic alopecia: a hospital based case control study

Background: Several previous studies have investigated the association between androgenetic alopecia (AGA) and metabolic syndrome (MS), with inconsistent results. Objectives of the study were to study the prevalence of metabolic syndrome in male patients of androgenetic alopecia and compare with control population and study the relationship of metabolic syndrome with different grades of AGA.Methods: This prospective hospital based case control study included 100 new clinically diagnosed males of androgenetic alopecia, and age and sex matched control group. Assessment for presence of various components of metabolic syndrome was done following a uniform protocol in cases and controls. AGA was classified as per Hamilton –Narwood classification, grade I to III was classified as mild –moderate and grade IV and higher as severe AGA.Results: Of the 100 male AGA patients (age range 21-50, mean 34.49), 36 had grade II AGA, 24 had grade III AGA, 20 had grade IV AGA, 15 had grade V AGA and 5 had grade VI AGA. Among AGA patients, 60 of patients had mild-moderate AGA and 40 patients had severe AGA. Metabolic syndrome was statistically significantly more common in patients with AGA compared to controls. Among patients of AGA, metabolic syndrome was statistically significantly present in severe AGA compared to mild-moderate AGA. Among the evaluated parameters, like blood pressure, fasting blood sugar, dyslipedemia, abdominal obesity, all were significantly more common in AGA patients compared to controls except abdominal obesity.Conclusions: In the present study, metabolic syndrome was found to be 4.6 times more common in patients of androgenetic alopecia as compared to controls, being statistically significant, and more common in those with severe grades. This suggests that androgenetic alopecia patients especially with severe grades are at risk of metabolic syndrome and other cardiovascular diseases

Impact of Ageratum conyzoides L. on the diversity and composition of vegetation in the Shivalik hills of Himachal Pradesh (Northwestern Himalaya), India

The flora of the Shivalik hills of Himachal Pradesh, India is under threat due to the rapid invasion of invasive species. Invasive species means an alien species, which becomes established in natural or semi-natural ecosystems and threatens native biological diversity. In their new regimes they show diverse life forms, habit, morphology, reproductive biology, grow fast, have the ability to grow under different habitats, produce enormous number of very small, light weight seeds that and can-survive in soil for years helping long distance dispersal and spread. They can out-compete native species, reduce wildlife habitat potential, alter natural ecosystem processes and limit overall biodiversity. Ageratum conyzoides is one such widely adaptive weed from sub-tropical America that has entered in the Shivalik hills of Hamrpur district of Himachal Pradesh. It has grown as monocultures, in grasslands, forests, agricultural, plantations and horticultural fields in Himachal Pradesh. Hence, it was decided to evaluate the impact of A. conyzoides on the diversity and floristic compositions of native species. It was found that as compared to control, in the Ageratum invaded area; the average number of plant species has reduced by 32.10%; the α diversity has reduced by 41.21% and the dry biomass of plants has also reduced significantly. It was concluded that invasion of A. conyzoides is drastically affecting the productivity and diversity of the invaded areas in Shivalik hills of Hamirpur district

Comparison of the safety and efficacy of caroverine and betahistine in patients of subjective tinnitus

Background: Owing to lack of any established treatment and handicap assessment methods, subjective tinnitus can be a debilitating disorder. This study was carried out to compare the safety and efficacy of caroverine and betahistine in patients of subjective tinnitus.Methods: A total of 60 patients of subjective tinnitus were randomized into two groups and followed-up for 12 weeks using tinnitus handicap inventory (THI) questionnaire. One group received 8 mg betahistine tablet TDS for a month whereas the other group was given supervised intravenous (IV) infusion of 160 mg of caroverine dihydrochloride. Data for the safety were also recorded.Results: Both the drugs showed significant improvement in severity of symptoms at 1 week, 4 weeks and 12 weeks individually as assessed by the THI scores. The response to caroverine was significant up to 4 weeks, but it was not significant at 12 weeks; whereas the response to betahistine was significant up to 12 weeks. A total of 28 adverse drug reactions (ADRs) were reported (53.6% with caroverine, 46.4% with betahistine). 24 ADRs were mild and 4 were moderate in intensity. There was no serious adverse event.Conclusions: Both the drugs are safe and efficacious in reducing the handicap of subjective tinnitus. A single IV infusion of caroverine may suffice for 4-6 weeks, so it may be repeated after 6 weeks to maintain the relief

DSMC simulations of Mach 20 nitrogen flows about a 70 degree blunted cone and its wake

Numerical results obtained with the direct simulation Monte Carlo (DSMC) method are presented for Mach 20 nitrogen flow about a 70-deg blunted cone. The flow conditions simulated are those that can be obtained in existing low-density hypersonic wind tunnels. Three sets of flow conditions are simulated with freestream Knudsen numbers ranging from 0.03 to 0.001. The focus is to characterize the wake flow under rarefied conditions. This is accomplished by calculating the influence of rarefaction on wake structure along with the impact that an afterbody has on flow features. This data report presents extensive information concerning flowfield features and surface quantities

Research Notes : Genetic and altitude effects on seed protein content in soybean

Sixty germplasm lines were raised in replicated trial at 700 m above m.s.l. and 1300 m above m.s.l. in the western zone of sub-Himalayan region to understand the genetic and altitude effects on seed protein in soybean. A larger influence of genetic effect was recorded; however, an appreciable influence of altitude, and genotype x altitude interaction effects were also noticed. Expression of protein content was maximum at the lower altitude, as compared with higher altitude

DSMC calculations for 70-deg blunted cone at 3.2 km/s in nitrogen

Numerical results obtained with the direct simulation Monte Carlo (DSMC) method are presented for Mach 15.6 nitrogen flow about a 70-deg spherically blunted cone at zero incidence. This flow condition is one of several generated in the Large Energy National Shock (LENS) tunnel during tests of a 15.24 cm diameter model with an afterbody sting. The freestream Knudsen number, based on model diameter, is 0.0023. The focus of the DSMC calculations is to characterize the near wake flow under conditions where rarefaction effects may influence afterbody aerothermal loads. This report provides information concerning computational details along with flowfield and surface quantities. Calculations show that the flow enveloping the test model is in thermal nonequilibrium and a sizable vortex develops in the near wake. Along the model baseplane the heating rates are about 0.6 percent of the forebody stagnation value while the maximum heating along the sting is about 4.2 percent of the forebody stagnation value. Comparison of a Navier-Stokes solution with the present calculations show good agreement for surface heating, pressure, and skin friction results
