Role of NABARD in financing marine fisheries projects

National Bank for Agriculture and Rural Development Is the apex organisation dealing with the policy, planning and operational matters relates to credit for development of agriculture and allied sectors including marine fisheries. NABARD has been playing a significant role in promoting marine fisheries development as a refinancing agency as well as developmental agency through conducting training programmes, supporting innovative type of schemes and funding research projects. NABARD has been extending refinance assistance to schemes for acquiring fishing vessels, mariculture and for building Infrastructural facilities. The experiences of NABARD in Implementing various fisheries schemes (s discussed in this paper. The significant features of the pilot credit project Implemented in Orissa with BOBP assistance are highlighted. With view to increasing the participation of financial institutions in the process of marine fisheries development, suggestions are made to Improve flow of credit to marine fisherie

Repulsive Fermions in Optical Lattices: Phase separation versus Coexistence of Antiferromagnetism and d-Superfluidity

We investigate a system of fermions on a two-dimensional optical square lattice in the strongly repulsive coupling regime. In this case, the interactions can be controlled by laser intensity as well as by Feshbach resonance. We compare the energetics of states with resonating valence bond d-wave superfluidity, antiferromagnetic long range order and a homogeneous state with coexistence of superfluidity and antiferromagnetism. We show that the energy density of a hole $e_{hole}(x)$ has a minimum at doping $x=x_c$ that signals phase separation between the antiferromagnetic and d-wave paired superfluid phases. The energy of the phase-separated ground state is however found to be very close to that of a homogeneous state with coexisting antiferromagnetic and superfluid orders. We explore the dependence of the energy on the interaction strength and on the three-site hopping terms and compare with the nearest neighbor hopping {\it t-J} model

Physical method of upgradation for low grade wolframite pre-concentrate from Degana, Rajasthan

Tungsten is a strategic metal and mostly used in defence. It is also used in cutting tools, industrial, electrical, textile and leather sectors. India's tungsten reserves are very limited and the only workable deposit is restricted to Degana in Rajasthan. Tungsten deposit occurs in association with metamorphic rocks and granite igneous rock throughout the world. At Degana, two types of deposit are being worked at, one being quartz load wherein wolframite is mineralised in quartz vein and the other is finely disseminated tungsten mineralisation in the granite body. The sample under investigation belonged to off-grade tungsten pre-concentrate - I (PC - 1) produced at Degana Plant site, assaying 14.50% WOe 20.20% SiO, and 4.13% S. The objective of this study was to find the upgradation conforming to DMRL specification i.e. final wolframite concentrate with >65.0% WO,, and S and SiO, < 1.0% each. Detailed studies indicated that grinding the feed to 200 mesh followed by sulphide flotation at 4.5 and 8.0 pH and repeated vanning of non-sulphide could produce a wanner concen¬trate assaying 64.8% WO,. 1.0% SiO, and 3.0% S with a distribution of 48.8% WO3 in it. Thorough desliming followed by sulphide flotation and then treating on vanner times could produce a concentrate analysing 68.47% WO j, 0.5% SiO3 and 0.48% S which conforms to the DMRL sped¬fications

Research Notes : India : Performance of winter soybean under varying levels of irrigation

Possibility of growing soybean during winter season has been revealed by several workers (Sarmah, 1979; Mandloi and Tiwari, 1971). But the success of a winter crop depends mainly on available soil moisture. The average rainfall for the last ten years at the station during winter months (November to March) was 104.28 rrun, which is not enough to sustain a good crop of soybea

Effect of Silver on the Sintering Characteristics of High T Ceramic Superconductors

A detailed investigation on the densification behaviour of Y-Ba-Cu-oxide (YBCO)-AgX and Bi-Pb-Sr-Ca-Cu-oxide (BPSCCO)-AgX composite powder synthesised by a chemical pyrophoric decomposition technique is made. It has been observed that Ag plays a significant role on the lowering of sintering temperatures and melting points of these superconductors. In YBCO-AgX, for 0< x<_0.6 the rate of densification increases and for 0.6<x<1.2 the rate of densification decreases. The densification behaviour is due to oxygen absorption at the interface of YBCO and Ag grains and a low temperature eutectic Ag,,OX formed which promotes liquid phase sintering. Studies on the sintering characteristics under inert atmosphere indicate increased densification with the silver addition. The removal of oxygen from Ag,OX to the inert sintering atmosphere enhances the densification rates . This is also confirmed from the weight loss of the pellets observed in the TG experiments. Sintering studies of BPSCCO-AgX composites show decrease of densification with the Ag content in the matrix. The degradation of superconducting properties is attributed to the change of chemical compositions of the composites. The evaporation loss of Bi, Pb, Sr and Cu during sintering is observed to be the cause of degradation. The evaporation losses are increased with x

Role of the van Hove Singularity in the Quantum Criticality of the Hubbard Model

A quantum critical point (QCP), separating the non-Fermi liquid region from the Fermi liquid, exists in the phase diagram of the 2D Hubbard model [Vidhyadhiraja et. al, Phys. Rev. Lett. 102, 206407 (2009)]. Due to the vanishing of the critical temperature associated with a phase separation transition, the QCP is characterized by a vanishing quasiparticle weight. Near the QCP, the pairing is enhanced since the real part of the bare d-wave p-p susceptibility exhibits algebraic divergence with decreasing temperature, replacing the logarithmic divergence found in a Fermi liquid [Yang et. al, Phys. Rev. Lett. 106, 047004 (2011)]. In this paper we explore the single-particle and transport properties near the QCP. We focus mainly on a van Hove singularity (vHS) coming from the relatively flat dispersion that crosses the Fermi level near the quantum critical filling. The flat part of the dispersion orthogonal to the antinodal direction remains pinned near the Fermi level for a range of doping that increases when we include a negative next-near-neighbor hopping t' in the model. For comparison, we calculate the bare d-wave pairing susceptibility for non-interacting models with the usual two-dimensional tight binding dispersion and a hypothetical quartic dispersion. We find that neither model yields a vHS that completely describes the critical algebraic behavior of the bare d-wave pairing susceptibility. The resistivity, thermal conductivity, thermopower, and the Wiedemann-Franz Law are examined in the Fermi liquid, marginal Fermi liquid, and pseudo-gap doping regions. A negative next-near-neighbor hopping t' increases the doping region with marginal Fermi liquid character. Both T and negative t' are relevant variables for the QCP, and both the transport and the motion of the vHS with filling suggest that they are qualitatively similar in their effect.Comment: 15 pages, 17 figure

Estimation of Phreatic Line Using Dimensional Analysis

A new technique using dimensional analysis (D.A.) is presented here to draw profile of phreatic line through an earthen dam. A universal equation is formulated using D.A. to get numerous points on a steady-state phreatic surface. The prediction of phreatic line using D.A. is then compared with those of conventional methods by Kozeny, A. Casagrande, Stello and also with centrifuge model test results and large scale prototype field results to evaluate applicability of this equation. It has been observed that D.A. can predict the results reasonably well. Thus Dimensional Analysis method can prove to be an easy and sufficiently accurate method to predict solutions to complex and multiparameter problems

Evaluation of Grass Bales Stored under Cover and Plinth System of Storage

The feed and fodder requirement for dairy animals is primarily met by roughages, green fodder and homemade concentrate mixtures. Roughages are high in crude fibrous material which essentially consists of cellulose, hemi-cellulose and to some extent lignin. Livestock production is backbone of Indian Agriculture and source of employment in rural areas for centuries. To meet the demand of feeding these huge livestock population an adequate supply of feed throughout the year is the prerequisite for successful animal production programmes. A huge gap between demand and supply of feed and fodder exists in our country. This huge gap between requirement and availability of livestock feeds like dry fodders, green fodders could however be bridged by proper post harvest management of all kind of forage resources and search for alternate source of protein rich forage supplement. The most common livestock feed resources are crop reduces (straw, stover, haulms etc). All of these fodder resources are highly voluminous and having lower density varying from 40-70 kg/m3 due to which there transportation, storage and handling are very cumbersome and expensive and therefore cannot be utilized up to a maximum extent. Storage is a repeated phase during transit of agricultural produce and the product needs to be stored from one harvest to next thus, demanding additional carry over as safe guard, against speculation in price and market demand or against shortage and famine
