Accurate estimations of circumstellar and interstellar lines of quadruply ionized vanadium using the coupled cluster approach

Accurate {\it ab initio} calculations have been carried out to study the valence electron removal energies and oscillator strengths of astrophysically important electromagnetic transitions of quadruply ionized vanadium, $V^{4+}$. Many important electron correlations are considered to all-orders using the relativistic coupled-cluster theory. Calculated ionization potentials and fine structure splittings are compared with the experimental values, wherever available. To our knowledge, oscillator strengths of electric dipole transitions are predicted for the first time for most of the transitions. The transitions span in the range of ultraviolet, visible and near infrared regions and are important for astrophysical observations.Comment: Submitted in Astrophysical

SYNTHETIC AND ANTIMICROBIAL ACTIVITY OF 4 THIAZOLIDINONES

Objective: Thiazolidinone, a saturated form of thiazole with carbonyl group on the fourth carbon, has been considered as magic moieties (Wonder nucleus) which possess almost all types of biological activities. This diversity in the biological response profile has attracted the attention of many researchers to explore this skeleton to its multiple potential against several activities Methods: Looking to the importance of N and S hetero cycles in the medical field, 4-thiazolidinone derivatives (3b,4b) have been synthesized by cyclization of substituted imines(1a,2a) with mercaptoacetic acid in presence of anhydrous ZnCl2 as a catalyst in DMF. The 4-thiazolidinone derivatives have also been tested against two bacterial strains viz. S. aureus and E. coli and two fungal pathogens viz. A. niger and C. albicans using Kirby-Bauer method. Result: New series of azomethines and 4 thiazolidinones compounds have been prepared. The synthesized compounds were characterized on the basis of IR, 1H-NMR, and elemental analysis. The purity of the compounds was checked using pre coated TLC plates (MERCK) using n-hexane: ethyl acetate (8:2) solvent system. The synthesized compounds show good antimicrobial acivity. Conclusion: The zone of inhibition is directly proportional to the degree of sensitivity of the bacterial, fungal strain and concentration of compound under test. A systematic perusal data of antimicrobial activity reveals that, with the increase in concentration of drug, increase in zone of inhibition occur in petridish. Better antimicrobial activity have been pointed out in synthesized compounds

Relativistic calculations of the lifetimes and hyperfine structure constants in 67^{67}Zn+^{+}

This work presents accurate {\it ab initio} determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying excited states in $^{67}$Zn$^{+}$, which is one of the interesting systems in fundamental physics. The coupled-cluster (CC) theory within the relativistic framework has been used here in this calculations. Long standing demands for a relativistic and highly correlated calculations like CC can be able to resolve the disagreements among the lifetime estimations reported previously for a few low-lying states of Zn$^{+}$. The role of different electron correlation effects in the determination of these quantities are discussed and their contributions are presented.Comment: 9 pages, 1 figure. submitted to J. Phys.

Study of the Efficacy of Malathion Impregnated Cotton Cords in Housefly Control

A comparative study on the efficacy of malathion impregnated cords on 13 mm and 22 mm circumference in housefly control has been carried. The results have shown that 13 mm cord is more economical weight for weight, but both afford protection from four to five months. Other factors like temperature and humidity which influence the efficacy of cords are discussed

Tillage Management Strategy in Fodder-Food Cropping System for Sustainable Production

The per capita availability of land is consistently decreasing, while food and fodder demand is increasing. Indiscriminate and injudicious use of farm inputs for achieving potential yield of crops has not only enhanced the cost of cultivation but also threatened the environment and sustainability of the system. Combination of these factors and their interface are serious threats to agriculture and mankind. In rainfed condition of central India, fodder sorghum+cowpea –wheat is potential cropping system among farmers maintaining 2-4 livestock’s. The conventional tillage system which inverts and mixes the soil, introduces large amounts of oxygen into the soil and thus stimulates aerobic micro-organisms. Use of no till system in agriculture also reduces the rate of soil organic matter loss (Doran and Smith, 1987). There is lower labor, energy, and machinery costs associated with no-till farming relative to conventional tillage systems (Uri, 2000). In view of escalating energy cost and associated ill effects of conventional tillage practices, it is become imperative to optimize tillage requirement of fodder – food cropping system

Computing welfare losses from data under imperfect competition with heterogeneous goods

We study the percentage of welfare losses (PWL) yielded by imperfect competition under product differentiation. When demand is linear, if prices, outputs, costs and the number of firms can be observed, PWL is arbitrary in both Cournot and Bertrand equilibria. If in addition, the elasticity of demand (resp. cross elasticity of demand) is known, we can calculate PWL in Cournot (resp. Bertrand) equilibrium. When demand is isoelastic and there are many firms, PWL can be computed from prices, outputs, costs and the number of .rms. In all these cases we find that price-marginal cost margins and demand elasticities may influence PWL in a counterintuitive way. We also provide conditions under which PWL increases or decreases with concentration

A prospective study to compare the efficacy of vilazodone and escitalopram tablets in the treatment of patients with newly diagnosed major depressive disorder

Background: With the availability of large number of anti-depressant drugs, a thorough knowledge of comparative efficacy of the commonly used antidepressants is necessary to prescribe best drug molecule to the patient. This improves the compliance and therapeutic outcome. The aim of the study is to compare the efficacy of vilazodone and escitalopram in the treatment of patients with newly diagnosed major depressive disorder in a prospective study.Methods: 200 patients attending the psychiatry out-patient department diagnosed with major depressive disorder were assessed and enrolled into vilazodone 40 mg and escitalopram 20 mg treatment groups. Hamilton depression rating scale score (HDRS) was used to assess the severity of depression disorder at regular intervals.Results: Maximum cases were in the 21-30 age group and minimum cases in above 60 years age group. Males contributed maximum to number of depression cases with respect to females in both the treatment groups. Both escitalopram and vilazodone therapy group showed onset of improvement   at the end of 1st week. The efficacy of both treatment arms in reducing HDRS is comparable till 2nd week of treatment, but at 6th month vilazodone was more efficacious than escitalopram therapy. Conclusions: Escitalopram tablet given once/twice daily is significantly effective in reducing HDRS score as early as 2nd week. At 6th month vilazodone tablet was more efficacious than escitalopram therapy. Vilazodone is safe with fewer adverse effects as compared to escitalopram.
