Geo-spatial technology application for prioritization of land resources in Udham Singh Nagar District of Uttarakhand, India
595-603A loss of soil resources by prolific watersheds is a frequent problem confronting hydrologists and watershed managers. Soil erosion is a major factor in losses of soil. Different models are used for prediction of the amount of soil loss by erosion. In the present study, modelling using Revised Universal Soil Loss equation (RUSLE) is integrated with Remote Sensing (RS) and Geographical Information Systems (GIS) techniques and employed to estimate soil erosion and prioritization of watersheds of Udham Singh Nagar district of Uttarakhand, India. The results showed that Udham Singh Nagar district’s major portion (38.66%) is covered with agriculture land and only 17.57% area is covered with forest. Water-bodies have occupied 2.18% area of US Nagar district. A large variation has been noticed in case of built-up land which has been recorded as 5.71%. US Nagar has more agricultural land. Udham Singh Nagar is having plane topography hence the range of soil erosion is from 0 to 40 ton/ha/year. However, most region of Udham Singh Nagar district falls under the category of 0-2 ton/ha/year soil erosion. The value of soil losses in most of cases is less than 1 t/ha/yr except in case of 11 watersheds, where it is slightly higher than 1 t/ha/yr. Moreover, it has been concluded that major portion of Udham Singh Nagar district were slight prone category of soil erosion, and therefore, no major plan/activity is required for reducing soil losses. Only checking large amount of runoff and enhancing organic matter build up in the soil will suffice the purpose

Event-by-event correlations between () hyperon global polarization and handedness with charged hadron azimuthal separation in Au+Au collisions at from STAR
Global polarizations () of () hyperons have been
observed in non-central heavy-ion collisions. The strong magnetic field
primarily created by the spectator protons in such collisions would split the
and global polarizations (). Additionally, quantum chromodynamics (QCD) predicts
topological charge fluctuations in vacuum, resulting in a chirality imbalance
or parity violation in a local domain. This would give rise to an imbalance
() between left- and right-handed
() as well as a charge separation along the magnetic field,
referred to as the chiral magnetic effect (CME). This charge separation can be
characterized by the parity-even azimuthal correlator () and
parity-odd azimuthal harmonic observable (). Measurements of
, , and have not led to definitive
conclusions concerning the CME or the magnetic field, and has not
been measured previously. Correlations among these observables may reveal new
insights. This paper reports measurements of correlation between and
, which is sensitive to chirality fluctuations, and correlation
between and sensitive to magnetic field in Au+Au
collisions at 27 GeV. For both measurements, no correlations have been observed
beyond statistical fluctuations.Comment: 10 pages, 10 figures; paper from the STAR Collaboratio

Measurement of and binding energy in Au+Au collisions at = 3 GeV
Measurements of mass and binding energy of and
in Au+Au collisions at GeV are
presented, with an aim to address the charge symmetry breaking (CSB) problem in
hypernuclei systems with atomic number A = 4. The binding energies
are measured to be MeV and MeV for and , respectively. The measured binding-energy difference
is MeV for ground states. Combined with
the -ray transition energies, the binding-energy difference for excited
states is MeV, which is negative and
comparable to the value of the ground states within uncertainties. These new
measurements on the binding-energy difference in A = 4 hypernuclei
systems are consistent with the theoretical calculations that result in
and present a new method for the study of CSB effect using relativistic
heavy-ion collisions.Comment: 8 pages, 5 figure

Not AvailableA limnological investigation of the manmade reservoir is necessary to evaluate the potential fish production and to provide information that could be useful in fisheries development planning. In this direction, the present study was conducted on Nanak Sagar reservoir located on Deoha River in the Tarai region of Uttarakhand. The reservoir was divided into three zones viz., in Riverine, Transitional and Lacustrine. Fourteen hydrological parameters were analyzed for various seasons such as Monsoon, Post-monsoon and Pre-monsoon from July 2014 to June 2015. The assessment of water quality of the reservoir reflects the uses of water, as well as the condition of the site from where water sample was taken. It is also noteworthy that when intensive sampling has been carried out throughout a reservoir basin to generate a “true” mean for the more common trophic state variables such as nitrogen, phosphorus and silicate concentrations, the volume weighted mean values have often been statistically indistinguishable from those measured in the different zone. Tropic status of the reservoir was mesotropic in nature found on the basis of hydrological indices. Good status of water quality of this reservoir is essential for the development of culture and capture based fisheries.Not Availabl

Not AvailableMicrobial biofilms are gaining importance in agriculture, due to their multifaceted agronomic benefits and resilience to environmental fluctuations. This study focuses on comparing the influence of single inoculation-Azotobacter chroococcum (Az) or Trichoderma viride (Tv) and their biofilm (Tv-Az), on soil and plant metabolic activities in wheat and cotton grown under Phytotron conditions. Tv-Az proved superior to all the other treatments in terms of better colonisation, plant growth attributes and 10-40% enhanced availability of macronutrients and micronutrients in the soil, over control. Confocal and scanning electron microscopy showed that the cells attached to the root tips initially, followed by their proliferation along the surface of the roots. Soil polysaccharides, proteins and dehydrogenase activity showed several fold enhancement in Tv-Az biofilm inoculated samples. Time course studies revealed that the population of Az and Tv in the rhizoplane and rhizosphere was significantly higher with a 0.14-0.31 log colony-forming unit (CFU) increase in the biofilm-inoculated treatment in both crops. Enhancement in soil biological activities was facilitated by the improved colonisation of the biofilm, due to the synergistic association between Tv and Az. This demonstrates the utility of Tv-Az biofilm as a multifunctional plant growth promoting and soil fertility enhancing option in agriculture.Not Availabl

Not AvailableSince independence, Indian agriculture has made rapid strides in different perspectives because of innovative interventions
through developmental programmes by different institutions of the country. Today agriculture is very rapidly transforming
towards agribusiness. For this gaol, MANAGE is playing a very crucial role by implementing a central sector scheme named
as 'Agriclinics and Agribusiness Centers (ACABC)' which was launched by Ministry of Agriculture and Farmers' Welfare
(MoA&FW), Government of India in 2002. The main objective of the scheme is to supplement the public extension system
through agripreneurs and provide gainful self-employment opportunities to the unemployed agricultural graduates through
agribusiness. Till now the success rate of the scheme is not up to the expected level as trained candidates were facing
constraints in starting the agribusiness. This resulted in a delay for starting the agribusiness or failed to start it by the trained
candidates. Therefore a study was undertaken in Uttar Pradesh and Telangana states to investigate the constrained in starting
the agribusiness after completion of the training under ACABC scheme. A total of 120 agripreneurs were interviewed with a
semi-structured questionnaire to find out the constraints and also focus group discussion was conducted to know different
constraints. A research synthesis approach (purely a qualitative research design) was utilized to analyze the collected data
thematically. The roots of the problems were outlined through the problem tree analysis, hence potential strategies have been
proposed through objective tree and logical framework analysis (LFA) to handle the constraints faced by trained candidates.
By overcoming these constraints with suggested strategies, the agribusiness establishment can be increased under the
ACABC scheme.Not Availabl
