String-Dust Distributions with the Kerr-NUT symmetry

We attempt to solve the Einstein equations for string dust and null flowing radiation for the general axially symmetric metric, which we believe is being done for the first time. We obtain the string-dust and radiating generalizations of the Kerr and the NUT solutions. There also occurs an interesting case of radiating string-dust which arises from string-dust generalization of Vaidya's solution of a radiating star.Comment: 15 pages, TeX version. tex error correcte

Study of Parasite Hosts of the Genus Cuscuta and its Traditional Uses in Planpur Taluka, Gujarat, India

Cuscuta is a parasitic plant belonging to family Cuscutaceae. The present paper is an investigation of its various host plant species and its traditional uses in Palanpur Taluka of North Gujarat during 2005-2008. Two species of Cuscuta occur in the Palanpur Taluka. The preservation and documentation of traditional knowledge is a matter of prime importance. This will not only provide recognition of this knowledge but will also help in conservation of such gradually vanishing endangered semi/arid plant species. The present paper provide ethnomedicinal information of 2 species of Cuscuta. For each plant species listed, the botanical name, family, vernacular name, part used, uses/ailments treated, preparations/administrations, use (%) and locality are given

Global monopole as dual-vacuum solution in Kaluza-Klein spacetime

By application of the duality transformation, which implies interchange of active and passive electric parts of the Riemann curvature (equivalent to interchange of Ricci and Einstein tensors) it is shown that the global monopole solution in the Kaluza-Klein spacetime is dual to the corresponding vacuum solution. Further we also obtain solution dual to flat space which would in general describe a massive global monopole in 4-dimensional Euclidean space and would have massless limit analogus to the 4-dimensional dual-flat solution.Comment: 8 pages, LaTEX versio

Ethno-medicinal Plants used for Amenorrhoea and Abnormal Menstruation Diseases in Danta Taluka (Gujarat)

The present paper deals with species of flowering plants commonly used by different Adivasi communities to cure amenorrhoea and abnormal menstruation diseases and disorder. The cause of disease, its symptoms, and plant organs utilized and methods of preparation of remedies are provided. Tribes associated with specific remedial preparation have been mentioned, however, they may not be always exclusive since Adivasi communities are widely distribution in Danta Taluka and have considered communication with each other. It is hoped that the present study will not only confirm earlier findings recorded in literature, but also provide additional clues in this fields of vital interests. The Danta taluka is situated between 24° - 24’’ to 24° - 30’’ N latitudes and between 72° - 45’’ to 73° - 30’’ E longitudes. In the north it is bounded by Rajasthan State, in the south by the Mahesana District, in the east by the Sabarkantha district and in the west by Palanpur and Vadgam taluka. The total area of the Danta taluka is 86074.75 sq.km. Danta taluka has 187 villages and forest area of 47941.97 hectare. Tribals in Danta taluka mainly cast Adivasi which sub-tribes are Bumbadiya, Bhemiyat, Dabhi, Dhrangi, Gamar, Kodarvi, Laur, Makvana, Parghi, Parmar, Rohisa, Solanki and Taral are main tribal group inhabiting this area

Singularity Free Inhomogeneous Models with Heat Flow

We present a class of singularity free exact cosmological solutions of Einstein's equations describing a perfect fluid with heat flow. It is obtained as generalization of the Senovilla class [1] corresponding to incoherent radiation field. The spacetime is cylindrically symmetric and globally regular.Comment: 6 pages, TeX, to appear in Class.Quant.Gra

Ethno-medicinal Plants Used for Gonorrhoea Diseases in Danta Taluka (Gujarat)

The present paper deals with species of flowering plants commonly used by different Aadeevasee communities to cure gonorrhoea diseases. The cause of disease, its symptoms, and plant organs utilized and methods of preparation of remedies are provided. Tribes associated with specific remedial preparation have been mentioned, however, they may not be always exclusive since Adeevasee communities are of wide distribution in Danta taluka and have considered communication with each other. It is hoped that the present study will not only confirm earlier findings recorded in literature, but also provide additional clues in this field of vital interests

Promoting positive communication environments: a service evaluation.

Purpose The purpose of this paper is to present an evaluation of a programme of training and support provided to staff, which aimed to encourage supported communication environments for people with learning disabilities. Design/methodology/approach Training, monitoring and support for communication, specifically augmentative and alternative communication (AAC) strategies, was provided by speech and language therapy staff to two residential services over 46 weeks. Staff and service user communications were observed pre- and post-intervention. Findings In one provision there was an increase in service user initiations and the use of some AAC strategies by support staff. In the other provision there was no change in service user initiations and a decrease in the range of AAC strategies used. It appears that some forms for AAC remain challenging for staff to implement. Originality/value This evaluation explores ways of using specialist support services to improve communication environments for people with learning difficulties. Possible reasons for differences in the outcome of the intervention are discussed. Future research into the types of communication interactions experienced by people with learning disabilities across the range of communication styles may be useful so that support staff can be better helped to provide sustained and enriched communication environments

Formulation and Evaluation of Floating Oral In Situ Gelling System of Amoxicillin

Purpose. Effective Helicobacter pylori eradication requires delivery of the antibiotic locally in the stomach. High dose of amoxicillin (750 to 1000 mg) is difficult to incorporate in floating tablets but can easily be given in liquid dosage form. Keeping the above facts in mind, we made an attempt to develop a new floating in situ gelling system of amoxicillin with increased residence time using sodium alginate as gelling polymer to eradicate H. pylori. Methods. Floating in situ gelling formulations were prepared using sodium alginate, calcium chloride, sodium citrate, hydroxypropyl methyl cellulose K100, and sodium bicarbonate. The prepared formulations were evaluated for solution viscosity, floating lag time, total floating time, and in vitro drug release. The formulation was optimized using a 32 full factorial design. Dissolution data were fitted to various models to ascertain kinetic of drug release. Regression analysis and analysis of variance were performed for dependent variables. Results. All formulations (F1–F9) showed floating within 30 s and had total floating time of more than 24 h. All the formulations showed good pourability. It was observed that concentration of sodium alginate and HPMC K100 had significant influence on floating lag time, cumulative percentage drug release in 6 h and 10 h. The batch F8 was considered optimum since it showed more similarity in drug release (f2 = 74.38) to the theoretical release profile. Conclusion. Floating in situ gelling system of amoxicillin can be formulated using sodium alginate as a gelling polymer to sustain the drug release for 10 to 12 h with zero-order release kinetics
