Carbon isotope studies on calcite - graphite system yield narrow Δ Cat - Gr values, varying from 3.9 to 4.3, indicating equilibrium between coexisting calcite and graphite. Calcite - graphite geothermometry has assigned temperatures ranging from 630° to 700°C for the calc - granulites found to the NE of Usilampatti area. The inferred temperatures correspond to the retrograde temperatures obtained by cation exchange thermometry on the granulites from other areas in the Madurai Block. These temperatures may correspond to the late isobaric cooling event. X-ray diffraction studies indicate well ordered nature of these graphites and corroborate the findings of isotope geothermometric inferences.Keywords

Carbon isotope records on carbonates from the Bhima basin are characterized by 13C enriched values (up to 4‰ PDB). These data are integrated with the available palaeontological records to suggest a Terminal Proterozoic (post - Varanger) age for the Bhima sediments. The carbon isotope compositions of Katamadevarhalli and Shahabad carbonates analysed in the present study exhibit two distinct trends. While the Katamadevarhalli carbonates show a positive trend, those from Shahabod display a negative trend from bottom to top, probably indicating long-term temporal trend of carbon isotope values.Keywords

Background:Terminalia arjuna is being used in various cardiovascular diseases as cardiotonic, diuretic&in hypercholesterolemia. Studies conflict each other for its mechanism of action. This study aims to investigate effect of 90% alcoholic extract of Terminalia arjuna on in vitro isolated rabbit's heart&to find its probable mechanism of action.Objective: To study the preliminary pharmacological effects of 90% alcoholic extract of Terminalia arjuna in-vitro on isolated heart, coronary blood flow, and to study its probable mechanism of action.
Material&Methods: Effect of Terminalia arjuna was observed on heart rate, coronary blood flow, amplitude on in vitro isolated perfused rabbit's heart mounted on langendorff apparatus&further cholinergic&adrenergic blockers were used to study the mechanism of action. Six experiments were conducted for each parameter&data was analysed using Student's t test.
Results: Terminalia arjuna causes mean percentage decrease of 7.26%, 9.31%&20.51% in heart rate, decrease of 10.34%, 16.64%, 20.51% in coronary blood flow&decrease of 15.11%, 12.61%, 11.65% in amplitude at 25μg, 50μg&100μg doses respectively. The decrease in heart rate, coronary blood flow&litude persists even after cholinergic&adrenergic blockers suggesting that cholinergic&adrenergic receptors are not involved in mechanism of Terminalia arjuna.
Conclusion: Terminalia arjuna cardiodepressant effect does not involve cholinergic&adrenergic receptors.

Peripheral vascular disease is a major macrovascular complication of diabetes mellitus. This study was done to determine the prevalence of peripheral arterial disease in type 2 diabetes mellitus using the ankle brachial pressure index. An 12 MHz doppler probe was used in the arms and legs to assess the ankle brachial index (ABI) in 200 type 2 diabetes mellitus patients aged more than 40 years. Thorough history of patients including age, smoking history, history of symptoms of peripheral arterial disease, complete physical examination and routine investigations were collected at the time of enrolment for all subjects. A ratio of the highest blood pressure from the posterior tibial or pedal arteries of each leg to the highest blood pressure from the brachial arteries < 0.9 was considered abnormal. Abnormal ABIs were found in 33% (66/200) patients with type 2 diabetes mellitus. 45.5% patients had ABI 0.80-0.89, 33.3% patients had ABI 0.50-0.79 and 21.2% patients had ABI <0.5 Prevalence of peripheral vascular disease in type 2 diabetes mellitus is on rise in northern India so there is need to educate the patients regarding risk factor modification and importance of early intervention to prevent future progression of peripheral vascular disease.Keywords

We present here the results of Laser-Raman Spectroscopic studies on graphite samples from the Archaean metasedimentary rocks of Dharwar craton to correlate the structural parameters of graphite with the metamorphic grade of the host rocks. The present studies show that the first order Raman peak (O) of the graphite samples appears in the wave number range from 1581 to 1585 cm-1; the second order Raman peak (S) appears in the wave number range from 2699 to 2721 cm-1; and the disorder Raman (D) peak appears in the wave number range from 1349 to 1356 cm-1. It is suggested that the intensity ratios of the Rarnan peaks (D/O)a are the inverse function of in-plane crystallite size of the graphite. The observed values of intensity ratio (D/O)h, varies from 0.095 to 0.591, (D/D+O)a varies from 0.18 to 0.46 and (S/O)h, varies from 0.21 to 0.32. This range of values indicates that the graphite samples are well crystallized. A correlation of (D/O) area ratios along with the in-plane crystallite size La (50 to 193 Å) and the metamorphic grade shows that the metamorphic grade of the host rocks of the studied samples lies in the range between upper chlorite zone and lower sillimanite zone. The estmated peak metamorphic temperatures of the host rocks are in the range of 575 to 625°C and they are in excellent agreement with temperatures obtained by the Powder X- ray diffraction studies and conventional geothermometry studies.Keywords

We report here., the results of powder x-ray diffraction studies on six graphite samples from the Archaean metasedimentary rocks of Dharwar craton, with the motivation of correlating the graphitization process of carbonaceous matter during metamorphism with metamorphic grade. Our studies show that interplanar spacing d(002) and crystallinity Lc(002) for all the studied samples are very close to that of well crystallized graphite.
The observed decrease in full width at half maximum (FWHM) of the (002) diffraction peak from 0.20 to 0.102 Å. increase in crystallite size, Lc(002) from 408 to 800 Å and graphitizing degree from 86 to 362 indicate different metamorphic grades. Our results indicate that the rocks from Hampapura are of low metamorphic grade and those from Arjun Bettahalli are highly metamorphosed. The peak metamorphic temperatures of metasedimentary rocks are estimated to be around 600±50°C. The temperature estimates based on graphite crystallinity studies and the temperatures estimated by silicate mineral geothermometry studies of the coexisting mineral assemblages were found to be consistent.

An experiment was conducted to examine the magnitude of genetic diversity and characters contributing to genetic diversity among 35 core elite wheat germplasm from INDIA and CIMMYT under water deficit condition. Principal components (PC) analysis showed that three components explained 67.73 per cent of the total variation among traits. The first PC contribute 38.8 per cent, second PC contribute 17.17 per cent and third PC contribute 11.66 per cent of total variation between traits. The first PC was more related to LSR, DSI, SCMR, RWC, ear weight per plant, harvest index and grain yield. The second PC was more related to plant height, LSR, tillers per plant, biological yield, thousand kernel weight and RWC. Therefore, selection based on first component is helpful for a good hybridization breeding program. Genetic divergence was carried out and grouped genotypes into six genetically distinct clusters. Cluster II genotypes viz., CHIRYA7, HW2041 and PBW502 shows superiority for functional stay green trait by exhibiting low cluster mean for leaf and DSI, and high cluster mean for SCMR, photosynthetic rate, RWC, tillers per plant, ear weight, 1000 kernel weight, biological yield, harvest Index, grain yield per plant and in contrast Cluster IV genotypes are non-stay green and drought susceptible by exhibiting high cluster mean for LSR and DSI. A three dimensional (3D Plot) depicts maximum genetic divergence between HW2041 and CBW38 and CHIRYA7 and HW2033. Stay green trait and all yield attributing traits except plant height can be improved by intermating HW2041 with CBW38 and CHIRYA7 with HW2033 genotypes which result in a highly heterotic hybrid for these traits under water deficit stress in wheat.Keywords

Carbon isotopic compositions of carbonate rocks from Narji and Koilkuntla Formations belonging to the Kurnool Group range frorn -1.5 to +2.2%0 and +3.1 to +4.3%0 respectively. 13C values on coexisting organic carbon are around -26%0. 87Sr/86Sr ratios of limestones from Koilkuntla Formation (0.7086 - 0.7104) exhibit less variation than those belonging to Narji limestones (0.7073 - 0.7132). Bivariant plots of 87Sr/86Sr and δ13C against Mn/Sr and δ18O show open system diagenetic trends for the carbonate rocks of Narji Formation. Similar plots for Koilkuntla Formation do not reveal any definite alteration trends. Comparison of carbon isotope data coupled with the least altered 87Sr/86Sr values of Narji and Koilkuntla limestones shows similarity in the isotopic ratios exhibited by other worldwide Late Neoproterozoic carbonate successions. This finding is corroborated by available age information on the underlying Cuddapah Supergroup of rocks as well as palaeontological evidences on the rock formations of Kurnool Group.Keywords

Open source software in libraries, with description of a variety of software packages and successful library projects. There are many shared principles between Open source software and Librarianship, especially the free and equal access to information. Because of the freedom we gain with the use of Open source software is it possible to have greater control over how libraries operate. Anybody who worked with computers on a daily basis can contribute to open source software because things like information architecture, usability testing, documentation, and staffing are key skills required for successful projects, and these skills are inherent in the people who use computers as a primary tool in the work.
Koha is a full featured Integrated Library System (ILS) specially meant for automation of library services and activities. DSpace is an Open Source Software package that provides the tools for management of digital assets, and is commonly used as the basis for an institutional repository.
Now the library and information sectors have become totally users oriented so the concept of ‘customer’s satisfaction’ also applies here and Open source software is essential in libraries to fulfill the user’s needs in appropriate manner. This paper highlights how the libraries are highly influenced by the digital resources especially the internet usage by the user community to retrieve information for various. This also highlights various features of the Open source software for Library Automation, Open source software for Digital Library and Institutional Repositories and Open source software for content management in libraries.

The present investigation is concerned with effects of distinct conductive and thermodynamic temperatures on reflection and transmission cofficients at an interface of two different micropolar viscothermoelastic solid half spaces. Reflection and transmission phenomenon of plane waves impinging obliquely at a plane interface between two different micropolar viscothermoelastic solid half spaces with two temperatures are investigated in the context of Green-Lindsay (G-L) theory (1972). The incident wave is assumed to be striking at the plane interface after propagating through one of the micropolar viscothermoelastic solid with two temperatures. Amplitude ratios of the various reflected and transmitted waves are obtained in closed form and it is found that these are function of angle of incidence, frequency and are affected by the micropolar, viscoelastic properties of the media. Viscosity effects are shown on these amplitude ratios for a specific model. Results of some earlier workers have also been deduced from the present investigation.Keywords
