Abstract

An experiment was conducted to study the effect of irrigation and nitrogen on pearl millet during summer 2010 at Anand Agricultural University, Anand. Twelve treatment combinations of four irrigation levels (0.4, 0.6, 0.8 and 1.0 IW: CPE ratio), three levels of nitrogen (80, 120 and 160 kg N ha^-1) were tested in split plot design with four replications. The result revealed that the frequent irrigations at 1.0 IW : CPE ratio significantly increased the plant height, tillers per meter row length and leaf : stem ratio and produced significantly the highest green forage, dry matter and crude protein yields and registered the highest net returns. However, lower irrigation level of 0.4 IW: CPE ratio was significantly superior in WUE than 1.0 IW : CPE ratio. Successive increase in nitrogen application increased yield attributes, leaf, stem ratio, crude protein content as well as WUE. Application of 160 kg N ha-1 recorded significantly the highest green forage, dry matter and crude protein yields of pearl millet and gave the highest net returns.

Abstract

In the present investigation solid dispersion of olanzapine has been prepared to improve its solubility. Further, using solid dispersion, mouth dissolving tablet was prepared to overcome the problem of swallowing. A Simplex Lattice design was applied using three factors, i.e. superdisintegrants like croscarmellose sodium(X₁) crospovidone(X₂), and sodium starch glycolate(X₃) in tablet formulation. Disintegration time and T₅₀ (Time required to 50% drug release) taken as responses. Solid dispersion showed significant enhancement in solubility of olanzapine. For mouth dissolving tablet, batch containing 5% croscarmellose sodium alone had minimum disintegration time (44 sec.) and faster drug release (T₅₀: 40 sec) compared to other batches.

Abstract

Objectives: The current manuscript presents a detailed study on physical properties of aggregates procured from all seventeen districts in Gujarat (India), having coarse aggregate availability. Methods/Analysis: Statistical analysis carried out shows that in Gujarat State (India) having 33 districts, coarse aggregates are available in 22 districts of which 5 districts have coarse aggregates supplied from common source. Hence leading to 17 districts having actual availability of coarse aggregates within themselves. Remaining 11 districts do not have any source of coarse aggregates, and thereby procure aggregates from nearby 7 districts. Findings: Technological advancement has led humanity to achieve new horizons of innovations in Concrete and Concrete Structures. With passage of time, we have come up with partial replacement of Cement by other materials, which lead towards environmental conservation by means of reduction in environmentally hazardous materials. We also have come up with partial replacement of sand. However when it comes to aggregates, we do not trust any other material as a partial or complete replacement to aggregates. Moral of the story is, binders (Cement) can be replaced, fillers (Sand) can be replaced, but in order to replace the material imparting strength (i.e. Coarse Aggregates), it demands a higher degree of reliability. As a part of findings for the current research, comparisons have been made for each property of coarse aggregates amongst all seventeen samples procured directly from field from the particular district. Novelty/Improvement: Utmost care has been taken pertaining to the authenticity of the information while procuring the samples. Results are interesting and give a clear cut understanding of difference in physical properties amongst the aggregates available in Gujarat province, India. Results can help in purpose specific selection of aggregates in Gujarat (India).
