A rapid and efficient protocol is developed for in vitro plantlet regeneration of Populus deltoides clone G48 using petiole explants. The highest frequency of shoot regeneration (74.75%) from petiole was obtained on MS medium supplemented with 0.50 mg/l BAP and 0.20 mg/l IAA. The regenerated shoots started turning brown and necrotic after 10–15 days in(More)
Biotechnology holds promise for genetic improvement of important vegetable crops. Broccoli (Brassica oleracea L. var. italica) is an important vegetable crop of the family Brassicaceae. However, various biotic and abiotic stresses cause enormous crop yield losses during commercial cultivation of broccoli. Establishment of a reliable, reproducible and(More)
This paper presents an application of Differential Evolution (DE) to determine optimal crop plan for command area of Pamba-Achankovil-Vaippar (PAV) link project, so as to maximize the net irrigation benefit. The mathematical model of the problem is linear in nature subject to various constraints due to availability of total land area, water, fertilizers,(More)
It has been recently shown [2] that the values of J T and J L which appear in Eq.(2) and (5) are too large by a factor of 4, in the Ref. [1]. Correcting for this changes the Fig. 2 (see below). Moreover , now the emissions from the quark matter dominate only for p T < 1 GeV/c. The basic result of the paper, that the upper limit of the single-photon(More)
We examine P b + P b collisions at CERN SPS energy 158 A GeV, by employing the earlier developed and recently refined parton-cascade/cluster-hadronization model and its Monte Carlo implementation. This space-time model involves the dynamical interplay of perturbative QCD parton production and evolution, with non-perturbative parton-cluster formation and(More)
With the advent of molecular biotechnology, plant genetic engineering techniques have opened an avenue for the genetic improvement of important vegetable crops. Vegetable crop productivity and quality are seriously affected by various biotic and abiotic stresses which destabilize rural economies in many countries. Moreover, absence of proper post-harvest(More)
AIM This work was carried out to study the hematologic profile of human immunodeficiency virus (HIV)-positive patients and its association with the clinicoimmunologic stage of the disease. MATERIALS AND METHODS A total of 187 patients with HIV, whether symptomatic or asymptomatic, diagnosed by enzyme-linked immunosorbent assay (ELISA) method according to(More)
Irrigation management has gained significance due to growing social needs and increasing command for food grains while the available resources have remained limited and scarce. Irrigation management includes optimal allocation of water for irrigation purposes, optimal cropping pattern for a given land area and water availabilities with an objective to(More)
A mathematical model has been developed for prediction of off axis ratio (OAR), using Wood - Saxon term used to represent nuclear potential. This method has been satisfactorily applied for predicting OAR in case of (60)Co γ-rays and high energy X-rays. Investigations are considered upto a depth of 25 cm in the case of 4MV LINAC for which measurements were(More)
Sixty patients of pulmonary tuberculosis selected through a specified selection procedure were followed up after one year of treatment. The psychiatric assessment was done by Present State Examination (P.S.E.) brief version and an open ended life event questionnaire. Results indicate that the non-life event group patients improved significantly (p<0.001)(More)
