Correlation among QPO frequencies and Quiescence-state Duration in Black Hole Candidate GRS 1915+105

We discover a definite correlation between the frequency of the quasi-periodic oscillations (QPO) in quiescence states and the duration of the quiescence state of the transient X-ray source GRS 1915+105. We find that while the QPO frequency can be explained with the oscillation of shocks in accretion flows, the switching of burst to quiescence states (and vice versa) and their duration can be explained by assuming an outflow from the post-shock region. The duration of the quiescence state is inversely related to the QPO-frequency. We derive this relation. We also find the correlation between the observed low ($\sim 0.001-0.01$Hz) and the intermediate (1-10Hz) QPO frequencies. Our analytical solutions are verified by analyzing several days of public-domain data from RXTE.Comment: Latex, 13 pages with 3 figures; Accepted for Publication in Astrophysical Journal Letter

Ethnobotanical Utilization of \u3cem\u3ePoecilineron pauciflorum\u3c/em\u3e Bedd. by the Kani Tribes of Agasthiamalai, Western Ghats, Tamil Nadu, India

This paper presents the Kani tribal uses of an endemic plant species, Poecilineuron pauciflorum Bedd. (Family Cluciaceae). The Kani tribals use it for the treatment of Mendel disorder and infectious diseases, and for exorcism activities. The information presented here was collected from the Kani community at Karaiyar, Kalakad Mundanthurai Tiger Reserve (KMTR) forest, South India, Tamil Nadu

Ethnomedicinal Uses of Plants in the Plains Area of the Tirunelveli-District, Tamilnanu, India

India has a rich heritage of using medicinal plants for indigenous uses and practices. Some of the country\u27s best herbal medicines have also been introduced worldwide, and new applications have been found for them in different parts of the world. This new found fame , however, has proven to be troublesome for India in some instances. For example, the “turmeric case” highlights the problems faced by this country in preventing bio-piracy. Traditional systems of medicine such as Ayurveda, Sidda, Unani, and homeopathy make use of more than 2000 plant species. Local People, medicinal practitioners and tribal healers of this country where oral tradition is closely followed, have made some of our medicinal plants world famous as they find diverse applications across the world. Traditional systems of medicine make use of nearly 7000 plant species. Out of the 17,000 economic species of angiosperms known worldwide, about 5000 occur in India. Of these, 3000 are medicinal plants in which root drugs constitute the largest number of species (680) followed by drugs originating from fruits (450). Bearing the above facts in mind, an attempt has been made here to enumerate the medicinal plants available in the Tirunelveli plains, with help of local people and medicinal practitioners. Approximately three hundred fifteen plants were at one time medicinally used in the plains area of the Tirunelveli district, of which 95 have been treated in the following account

Implementation of lean tools and techniques in an ethical papers production industry

Lean manufacturing (LM) is established as a best practice to improve the performance of manufacturing industries. Not all the manufacturing industries realize the benefits of LM practices specifically continuous process industries. The present research work is intended to study the advantages of implementing LM practices in an ethical paper industry which is a continuous production industry. Presently, the industry suffers with the problems such as lack of productivity, raw material wastes, underutilized resources, and lack of standard practices in the production. Gemba technique is adapted to record the information related to the present manufacturing environment. Based on the current state analysis, the feasible lean tools are selected and implemented such as 5S, Kaizen, and Total Productive Maintenance (TPM). The improvements have been noted as reduced tool change over time, reduced material wastes, effective utilization of resources and provide safety guidelines to workers and operations. The implications of these improvements increased the productivity also

How to Identify Rare and Endangered Ferns and Fern Allies

Identification of rare and endangered plant species is the first requirement for any conservation programme. The IUCN guideline is the only available method to identify the rare and endangered species and it requires vast data on the wild population of the target species. None of the biological characters, which are playing main role in the survival and distribution of several species, is used in IUCN guideline. In the meantime there are several difficulties in following IUCN guideline, particularly the non availability of complete field data. Moreover, the same guideline can not be used for all the groups of species in equal importance. The vascular cryptogams, pteridophytes, are also an important component of any mountainous flora and they have also to be conserved in nature. As they are the primitive vascular plants on the earth, they are getting depleted in the flora due to various reasons and it is the right time to identify the rare and endangered pteridophytes to conserve them. By considering various difficulties of IUCN method for the identification rare and endangered pteridophytes, a very simple method has been adopted by using just four criteria and this method can be applied to Pteridophytes from any region of the world
