    Deficiency of feed and fodder accounts for half of the total loss in dairy farming therefore, forages are called as backbone of livestock industry. The scarcity of green forages and grazing resources in the country has made the livestock to suffer continuously with malnutrition resulting in their production potentiality at sub-optimum level as compared to many developed nations (Anonymous, 2012). Arunachal Pradesh is well known for its ever green vegetation and biodiversity under hilly ecosystem. Though, it is situated at remotest part of country but possess huge scope of livestock farming. Namsai district of Arunachal Pradesh is a bordering district of Assam and having huge potential of milk production and its marketing which may help to improve the economic condition and poverty eradication of rural people. Cow is a major dairy animal here, however, the milk production capacity is very low as compared to other parts of the country. Dairy cow are reared in century old traditional way therefore, there are several areas of dairy management which needs improvement. Scarcity of feed and fodder is one of the major bottleneck which needs to be addressed urgently. Namsai district has very limited number of fodder crop and farmers mainly depend on non-conventional, public grazing land and forest vegetation. KVK Lohit (Namsai district) has introduced fodder sorghum in rainy and winter season for the first time in the district purposefully to improve the fodder availability under organized dairy farming in Namsai district

    A Note on the use of Ethnomedicine in Treatment of Diabetes by Mishing Communities in Assam, India

    Ethnomedicinal field surveys were conducted in several places of Sonitpur district and near by areas of Lakhimpur district in Assam, where diverse ethnic groups have lived since time immemorial. The ethnic groups have very rich tradition of herbal medicines used in the treatment of various ailments. Among the tribal communities, Mishings constitute the largest group along with Bodos. The ethnomedicinal information was collected on the basis of interview and field studies with local healers among those communities. Medicinal plants were collected and identified with help from indigenous healers. Such medicines have been shown to have significant healing power, either in their natural state or as the source of new products processed by them. Generally these formulations of crude products are considered moderate in efficacy and thus less toxic than most pharmaceutical agents. Our study is mainly concentrated with plants used in relation to cure of diabetes. In our report, detailed notes on the method of preparation, precise dosage, the part/parts of plants used and method of application is given. Scientific name, vernacular names and family names of the collected plants are also given in this report

    Signal Durations and local Richter magnitudes in northeast india: An empirical approach

    Twenty four analog seismic stations are operated by the Regional Research Laboratory (Jorhat), National Geophysical Research Institute (Hyderabad) and by the India Meteorological Department (IMD) in the Northeastern region (NER) of India. 8000 seismograms of 1992 shallow (5-30km) earthquakes recorded by these stations during the period from January 1985 to December 1999, have been used to establish relationships between signal durations and the local Richter magnitudes (ML). In order to obtain the empirical relations for the determination of duration magnitudes (MD), signal duration estimates have been fitted using regression analysis to models of the form Model-I: MD = C0 + C1 Log10 (S.D) + C2 Δ + C3 h Model-II: MD = C0 + C1 Log10 (S.D) + C2 Δ + C3 h + C4 [Log10 (S.D)]2, where S.D is the signal duration in seconds, Δ epicentral distance in degree and h focal depth in km. The models yielded duration magnitudes at each of the 24 stations having standard deviations as low as 0.07. For these stations, station factors are obtained by finding the average of the deviations of network magnitude (i.e. mean estimate of station magnitudes for each earthquake, denoted by MD A) from station magnitudes (MD) for the earthquake events in NER. Over - and under - estimations of station magnitudes with respect to ML are also determined for each station. It has been observed that the estimates of MD (A) scatter up to about 0.8units with respect to ML for both the models. Application of these factors reduced scatter down to ± 0.25 units for both the models. © Geol. Soc. India

    Grand unification in the minimal left-right symmetric extension of the standard model

    Full text link
    The simplest minimal left-right symmetric extension of the standard model is studied in the high energy limit, and some consequences of the grand unification hypothesis are explored assuming that the parity breaking scale is the only relevant energy between the electro-weak scale and the unification point. While the model is shown to be compatible with the observed neutrino phenomenology, the parity breaking scale and the heavy boson masses are predicted to be above 10^7 TeV, quite far from the reach of nowadays experiments. Below that scale only an almost sterile right handed neutrino is allowed with a mass M \approx 100 TeV

    Dicarbonylrhodium(I) complexes of pyridine alcohol ligands and their catalytic carbonylation reaction

    Get PDF
    Reaction of dimeric complex [Rh(CO)2Cl]2 with two molar equivalent of pyridine alcohol ligands (L) like 2-hydroxymethylpyridine (a), 3-hydroxymethylpyridine (b) and 4-hydroxymethylpyridine (c) afford the rhodium(I) dicarbonyl complexes [Rh(CO)2ClL](1a–c). The ligands are coordinated to the metal center through N-donor site. The complexes 1 undergo oxidative addition (OA) reactions with various alkyl halides (RI) like CH3I, C2H5I to produce Rh(III)complexes of the type [Rh(CO)(COR)IClL], where R = –CH3(2), –C2H5(3). Kinetic data for the reaction of 1 with CH3I indicate a first order reaction. The catalytic activity of the complexes 1 in the carbonylation of methanol was higher than that of the well known species [Rh(CO)2I2]−

    diphenylphosphinomethyl) ethane trichalcogenide ligands, [CH3C(CH2P(X)Ph2)3], where X= Se(a), S(b) and O(c) in 1:1 (metal:ligand) molar ratio to afford hexa-coordinated complexes of the type �2-(X,X)- [Ru(CO)2Cl2P3X3] (1a–c). The complexes 1a–c exhibit two equally intense �(CO) bands in the range 1979–2060cm−1 indicating cis-disposition of the two terminal carbonyl groups. The values of �(CO) frequencies containing different ligands, in general, follow the order: P3O3 >P3S3 >P3Se3 which may be explained in terms of ‘Soft–Hard’ (Ru(II)–O) and ‘Soft–Soft’ (Ru(II)–S/Se) interactions. The complexes have been characterized by elemental analyses, mass, 1H, 31P, 77Se and 13C NMR spectroscopy. The thermal stability of the complexes has also been studie

    Constrained analytical interrelations in neutrino mixing

    Full text link
    Hermitian squared mass matrices of charged leptons and light neutrinos in the flavor basis are studied under general additive lowest order perturbations away from the tribimaximal (TBM) limit in which a weak basis with mass diagonal charged leptons is chosen. Simple analytical expressions are found for the three measurable TBM-deviants in terms of perturbation parameters appearing in the neutrino and charged lepton eigenstates in the flavor basis. Taking unnatural cancellations to be absent and charged lepton perturbation parameters to be small, interrelations are derived among masses, mixing angles and the amount of CP-violation.Comment: To be published in the Springer Proceedings in the Physics Series under the heading of the XXI DAE-BRNS Symposium (Guwahati, India
