On the order of a non-abelian representation group of a slim dense near hexagon

We show that, if the representation group $R$ of a slim dense near hexagon $S$ is non-abelian, then $R$ is of exponent 4 and $|R|=2^{\beta}$, $1+NPdim(S)\leq \beta\leq 1+dimV(S)$, where $NPdim(S)$ is the near polygon embedding dimension of $S$ and $dimV(S)$ is the dimension of the universal representation module $V(S)$ of $S$. Further, if $\beta =1+NPdim(S)$, then $R$ is an extraspecial 2-group (Theorem 1.6)

Time Dependence of Brans-Dicke Parameter w for an Expanding Universe

We have studied the time dependence of w for an expanding universe in the generalised B-D theory and have obtained its explicit dependence on the nature of matter contained in the universe,in different era.Lastly we discuss how the observed accelerated expansion of the present universe can be accomodated in the formalism.Comment: 10 pages,No figure

THERMOSENSITIVE HYDROGELS–A POTENTIAL CARRIER FOR THE DELIVERY OF DRUGS AND MACROMOLECULES

In this review, the authors have discussed scientific advances in thermosensitive hydrogels over the past two decades. The ability of the thermo-sensitive hydrogel to undergo rapid changes with response to temperature makes it an attractive candidate for many biomedical applications such as targeted drug delivery, wound healing, soft contact lenses, sensors, tissue regeneration, gene, and protein delivery. This review aims to deliver a brief overview of gelation properties, merits, and demerits of various natural and synthetic thermo-sensitive polymers that have significant clinical relevance. The report emphasizes the importance of injectable thermosensitive hydrogels, as it can offer improved solubility of hydrophobic drugs and site-specificity, extended-release of drugs and macromolecules, improved safety, and local administration of drugs. The authors has also provided a commentary on the delivery of drugs or macromolecules from thermo-sensitive hydrogels through various approaches. This review highlights the current status of research in thermo-sensitive hydrogels and emphasizes the importance of developing nontoxic thermo-sensitive hydrogels, dual responsive, and multi-responsive hydrogel systems

Influence of rotation and sources of nutrients on soil properties and productivity of finger millet (Eleusinecoracana L. Gaertn.)

A field experiment was conducted at the All India Co-ordinated Research Project for Dryland Agriculture, UAS, GKVK, Bengaluru during kharif 2013-14. The experiment was laid out with 20 treatment combinations with three factors using factorial RBD with two replications comprised of on a permanent manurial trial with 35th crop cycle. Application of FYM at 10 t ha-1 has recorded significantly higher grain yield (1.76 t ha-1), maximum water holding capacity (MWHC) of 43.85 % and dehydrogenase activity (DHA) of 357.60?g TPF g-1 24 h-1 obtained after harvest of the crop as compared to application of maize residues at 5 t ha-1 (1.37 t ha-1, 42.27 % and 193.0?g TPF g-1 24 h-1 respectively) due to improved growth and yield parameters of finger millet. However, finger millet-groundnut rotation has given significantly higher grain yield (1.78 t ha-1), MWHC (43.66 %) and DHA (298.48?g TPF g-1 24 h-1) after harvest of the crop over mono cropping of finger millet (1.34 t ha-1, 42.46% and 252.12?g TPFg-1 24 h-1respectively ). Among different nutrient sources, application of organic matter with 100 % RDF have given significantly higher grain yield (2.74 t ha-1), MWHC (45.86 %) and DHA (431.13?g TPF g-1 24 h-1) after harvest of the crop compared to absolute control (0.28 t ha-1, 41.76 % and 133.67?g TPFg-1 24 h-1 respectively). The 100 % recommended dose of fertilizer + organic matter significantly increased yield attributes because of improved soil physical and chemical properties and increased microbial activity of the soil with continued application of organic matter

Entropy function for rotating extremal black holes in very special geometry

We use the relation between extremal black hole solutions in five- and in four-dimensional N=2 supergravity theories with cubic prepotentials to define the entropy function for extremal black holes with one angular momentum in five dimensions. We construct two types of solutions to the associated attractor equations.Comment: 15 pages, minor change
