Abstract

Fifty four progenies of Melia azedarach (Linn.) from eleven geographical locations were evaluated for leaf senescence, fruit characters and wood specific gravity. Large variations were recorded for leaf senescence period ranged from 35 to 119 days per year in 8-year-old progeny trial, however, few progenies remained semi-evergreen. Between progeny and within progeny differences were found significant. The narrow sense heritability (progeny basis, within progeny basis and individual plant basis) was calculated for all the characters. High heritabilities were recorded for fruit characters and specific gravity. Fruit characters have high genetic gain, whereas, specific gravity has low genetic gain. Genetic gain for within family selection was higher than family selection for all traits.

Abstract

This paper describes mineral chemistry of biotites from Jalor, Tosham and Jhunjhunu ring complexes of Malani igneous suite, India. The chemistry reveals iron enrichment trend in all the biotite samples of the three complexes. FeO*/MgO ratio is the highest (6.72) in Jalor samples whereas lower values of (4.08) and (3.72) have been observed in Tosham and Jhunjhunu samples respectively. Higher MgO has not affected the enhanced proportions of FeO in the biotites of Tosham and Jhunjhunu. Mg ⇌ Fe and 2A1 ⇌ 3Fe²⁺ substitution is dominant in Jalor samples whereas, influence of 3M ⇌ Al is deciphered in the Tosham and Jhunjhunu samples. Most of the biotites fall in the anorogenic (A-type) suites, representing extensional tectonic environment for their host rocks.

Abstract

The purpose of the present study was to examine the role of family relationship in child rearing of drug addiction afflicted and normal families. Sample for the present investigation was comprised of 270 students (7th to 10th classes) from Govt. High schools of rural areas (Mandoli, Harpalpur and Ajrawar) of Patiala district. Sample covered children who are from drug addiction afflicted families (N=135) as GrI and children from non-drug addiction afflicted families or normal families (N=135) as GrII. Family relationship inventory (Sherry & Smha, 1987) was used to measure three types of perceived parental attitudes, namely acceptance, concentration and avoidance. It was hypothesized that Family relationship in drug addiction afflicted families would be characterized by low concentration, low acceptance and high avoidance rejection as compared to normal families. T-ratio was used to analyze the data. The results of t-ratio revealed that Family relationships in GrI, i.e., students belonging to drug addiction afflicted families were characterized by significant higher attitude of avoidance that is abuse and rejection of children. Family relationships in GrII (normal families) were characterized by significant higher acceptance and concentration and very low on avoidance attitude toward children. Implications of the findings have been discussed.

Abstract

In the present analysis, the effect of quantum corrections on the gravitational instability of a viscoelastic fluid through porous medium in the presence of uniform magnetic field has been studied in the transverse and longitudinal mode of wave propagation. For the mathematical formulation of the physical problem Generalized Hydrodynamic and Hass model have been used. A general dispersion relation has been derived by using the normal mode analysis. The general dispersion relation is discussed separately for both the modes of wave propagation under the strongly and weakly coupling limits. It is found that the porosity of the medium and quantum effects modifies the Jeans criterion of instability for both the modes of wave propagation under the strongly and weakly coupling limits. Further, the effects of various parameters on the growth rate of gravitational instability has been numerically studied and depicted graphically.

Abstract

In the present paper the problem of Jeans instability of a self gravitating viscoelastic medium in the presence of nonuniform magnetic field for both longitudinal and transverse mode of wave propagation under the kinetic and hydrodynamic limits has been investigated, using the generalized hydrodynamic model. It is found that magnetic field has no effect on the Jeans criterion for the onset of gravitational instability in case of longitudinal mode of wave propagation, whereas it modifies the Jeans criterion in the case of transverse mode of wave propagation and has stabilizing effect on the onset of instability. Further, it is observed that the magnetic field has no effect on the growth rate of Jeans instability of a viscoelastic medium. The effects of shear viscosity, bulk viscosity and Mach number on the Jeans criterion and on the growth rate of Jeans instability have also been studied numerically and the obtained results are depicted graphically, for both strongly coupled plasma (SCP) and weakly coupled plasma (WCP).

Abstract

Sixteen weed control treatments viz. pinoxaden (40 g ha^-1), isoproturon (1250 g ha^-1) alone, isoproturon + pinoxaden (1000 + 40 g ha^-1), isoproturon + pinoxaden (750 + 30 g ha^-1), isoproturon + 2,4-D (1000 + 500 g ha^-1), isoproturon + metsulfuron-methyl (1000 + 4 g ha^-1), pinoxaden + 2,4-D (40 + 1000 g ha^-1), pinoxaden + metsulfuron-methyl (40 + 4 g ha^-1), isoproturon fb pinoxaden (1000 fb 40 g ha^-1), isoproturon fb pinoxaden (750 fb 30 g ha^-1), pinoxaden fb isoproturon (40 fb 1000 g ha^-1), pinoxaden fb isoproturon (30 fb 750 g ha^-1), pinoxaden fb 2,4-D (40 fb 1000 g ha^-1), pinoxaden fb metsulfuron-methyl (40 fb 4 g ha^-1), handweeding (30&60 DAS) and weedy check were evaluated at Palampur to study their effect on nutrient depletion by wheat associated weeds. Avena ludoviciana and Phalaris minor were the major weeds constituting 31 and 19.6%, respectively of total weed dry weight. Lolium temulentum, Vicia sativa, Anagallis arvensis and Coronopus didymus constituted 12.2, 17.1, 10.9 and 9.2%, respectively of the total weed dry weight. Weed control treatments significantly decreased total weed dry weight and thereby NPK depletion by weeds as compared to weedy check. Application of pinoxaden fb MSM (40 fb 4 g ha^-1) being statistically at par wih pinoxaden + MSM (40 + 4 g ha^-1), pinoxaden fb 2,4-D (40 fb 1000 g ha^-1) and hand weeding was significantly superior in reducing the total weed dry matter and nutrition depletion and increasing yield and NPK uptake as compared to the other herbicidal treatments. Weeds in weedy check removed 60.5 kg N, 14.8 kg P and 58.9 kg K ha-1 depriving thereby the wheat crop for that much amount of nutrients. Pinoxaden fb MSM (40 fb 4 g ha^-1) increased NPK uptake by wheat to 88.5, 19.2 and 49.6 kg/ha from 47.5, 9.1 and 29.2 kg/ha, respectively, that under weedy check.

Abstract

Many of the underexploited fruits have nutritional, therapeutic and medicinal values and holds lots of potential to become as new fruit crops. Dheu is among such potential fruits which is neglected from post harvest technological view point. It contains some valuable nutrients such as ascorbic acid and fibre and minerals. In dheu based toffee the acceptability scores was increased with blending with papaya. The product was found to be acceptable during storage upto 90 days. The results revealed that with the addition of papaya the ascorbic acid content of toffee decreased significantly from 31.20 mg/100g to 24.0 mg/100g. With increase in proportion of papaya pulp in dheu pulp, scores for texture of toffee decreased from 8.05 to 7.90. Similarly, the mean scores for overall acceptability for fresh toffee were 8.15 which decreased to 7.89 in toffee prepared with 50:50, dheu and papaya pulp. Although, the overall acceptability scores decreased with storage but the values ranged between liked moderately to liked very much. In the present scenario, where lot of emphasis is being laid on the consumption of health foods, development of such products may help the consumers to harness the nutritional and medicinal properties of such fruits.
