description: Various components of human development of poor households have been studied in North Bihar. The data has revealed that a higher proportion of females are chronically energy deficient than of males in the rural areas. The prevalence of chronic energy deficiency (CED) has been reported in both poor and non-poor households. The incidence of illiteracy and non-enrolment in schools have been found higher in the poor households, whereas the rate of completion of schooling has been observed comparatively high in the non-poor households. The study has further indicated low stake of poor households in the management of rural organizations. The analysis of determinants of poverty has suggested that level of poverty could be reduced through higher investments for the improvement of educational and nutritional status of the rural poor as well as launching of more rural development programmes. The study has observed that targeting of rural poor households in formulating strategies and implementing development programmes warrant special attention. These factors need to be addressed immediately for increasing their capability and skill so that they could be able to get out of poverty sphere. The improvement in social and human development aspects has been the per-requisite for implementation of any programme for poverty attenuation in Bihar.

description: Quantum communication has been leading the way of many remarkable theoretical results and experimental tests in physics. In this context, quantum communication complexity (QCC) has recently drawn earnest research attention as a tool to optimize the amounts of transmitted qubits and energy that are required to implement distributed computational tasks. On this matter, we introduce a novel multi-user quantum fingerprinting protocol that is ready to be implemented with existing technology. Particularly, we extend to the multi-user framework a well-known two-user coherent-state fingerprinting scheme. This generalization is highly non-trivial for a twofold reason, as it requires not only to extend the set of protocol rules but also to specify a procedure for designing the optical devices intended for the generalized protocol. Much of the importance of our work arises from the fact that the obtained QCC figures of merit allow direct comparison with the best-known classical multi-user fingerprinting protocol, of significance in the field of computer technologies and networking. Furthermore, as one of the main contributions of the manuscript, we deduce innovative analytical upper bounds on the amount of transmitted quantum information that are even valid in the two-user protocol as a particular case. Ultimately, comparative results are provided to contrast different protocol implementation strategies and, importantly, to show that, under realistic circumstances, the multi-user protocol can achieve tasks that are impossible by using classical communication alone. Our work provides relevant contributions towards understanding the nature and the limitations of quantum fingerprinting and, on a broader scope, also the limitations and possibilities of quantum-communication networks embracing a node that is accessed by multiple users at the same time.

description: In a recent article, W.-S. Hou and G.-G. Wong [Phys. Rev. D {\bf 67}, 034003 (2003)] have investigated the spectrum of two-gluon glueballs below 3 GeV in a potential model with a dynamical gluon mass. We point out that, among the 18 states calculated by the authors, only three are physical. The other states either are spurious or possess a finite mass only due to an arbitrary restriction of the variational parameter.

description: Variations in agricultural productivity in different states across the country are mainly due to large differences in the level of adoption of selected agricultural technologies and the underlying determinants of adoption of these technologies. Agricultural technologies selected in this paper include high-yielding varieties of seeds, chemical fertilizers, pesticides, use of machinery, etc. The pattern of adoption has been examined across the country based on the 54th round of NSSO dataset. The quantification of adoption has been carried out for each state in the form of a novel ‘adoption index’. The relation between adoption index and status of the infrastructure in the corresponding state has been examined. The strong correlation between adoption index and composite index of infrastructure and development has emphasized the need for improving infrastructure to increase adoption of improved agricultural technologies, which would increase the value of per hectare crop productivity. The functional analysis has revealed that infrastructures like electricity, irrigation, credit and extension organizations positively influence the adoption of the improved technologies. The study has suggested that there is a need to formulate policies which would help increase the availability of electricity, irrigation and institutional credit and improve the access to the extension organizations for the adoption of improved agricultural technologies and enhancement in productivity.

description: The study has revealed that agricultural research and development (R&D) has potential to offer long-term solutions to the problems of Indian agriculture. With the changing environment and supply-side constraints, the role of R&D has become more important. This realization alongwith past performance of agricultural R&D has convinced the government to commit a significant proportion of its resources for developing appropriate technologies. The ICAR-SAUs system has come out with a number of improved agricultural technologies for major agro-climatic conditions. The paper has provided a list of some of these technologies, which are capable of making farm operations easy, provide savings in resources, reduce production losses, improve product quality and increase shelf-life of products, etc. These technologies eventually provide higher availability of quality foods and higher farm income, including maintaining productive capacity of agro-ecosystems. Since some of the new technologies are information-intensive, the role of ICT has become more important alongwith empowerment of farmers with scientific know-how.

description: Farming systems of households in the western Uttar Pradesh have been analyzed based on the primary data collected through a sample of 197 farmers in 2004-05. The sugarcane- based farming system has been found predominant in the study area. Livestock, vegetables, cereals and sugarcane have been observed to be the main sources of farm income. The study has indicated that cross-bred breeding programme has not become popular due to low demand for milk of cross-bred cows. Credit has significant impact on farm income and credit requirement of about 86 per cent farmers is met by the institutional sources. Fragmentations and sub-divisions of landholdings, scarcity of labour, low yield of crops, less reliable markets, scarcity of owned-fund, depleting natural resources, non-availability of good quality seeds and sheds for poultry, etc. have been identified as the major constraints to promote integrated farming system in this area.

description: Light-shifts are known to be an important limitation to the mid- and long-term fractional frequency stability of different types of atomic clocks. In this article, we demonstrate the experimental implementation of an advanced anti-light shift interrogation protocol onto a continuous-wave (CW) microcell atomic clock based on coherent population trapping (CPT). The method, inspired by the Auto-Balanced Ramsey (ABR) spectroscopy technique demonstrated in pulsed atomic clocks, consists in the extraction of atomic-based information from two successive light-shifted clock frequencies obtained at two different laser power values. Two error signals, computed from the linear combination of signals acquired along a symmetric sequence, are managed in a dual-loop configuration to generate a clock frequency free from light-shift. Using this method, the sensitivity of the clock frequency to both laser power and microwave power variations can be reduced by more than an order of magnitude compared to normal operation. In the present experiment, the consideration of the non-linear light-shift dependence allowed to enhance light-shift mitigation. The implemented technique allows a clear improvement of the clock Allan deviation for time scales higher than 1000 s. This method could be applied in various kinds of atomic clocks such as CPT-based atomic clocks, double-resonance Rb clocks, or cell-stabilized lasers.

description: The authors make in this essay a critical analysis of the original text of John Stuart Mill [1861/1863] entitled “Utilitarianism”, in which the English author seeks to make two doctrines compatible: the doctrine of the greatest good for the greatest number of people and, the doctrine of ius naturalism that considers that there is an a priori moral canon that introduces absolute concepts such as intrinsic good or evil itself as criteria for decision-making. In this work, the influence that classical pragmatism exerted, and exerts, as a theory of legal thought and, above all, for action and decision is underlined. Utilitarianism interprets the world from various epistemological approaches, especially from law, economics an politics. The authors conclude that utilitarianism is justified as a valid precept for the application of positive law, in which the ac

description: The study has reported the impact of training on lac growers in terms of host utilization, livelihood conditions and income and employment generation. The study is based on the data collected from randomly selected 500 lac growers (trained and untrained) in the Ranchi and West Singhbhum districts of Jharkhand in the years 2003-04 and 2004-05. The host utilization has been found to increase significantly after training of lac growers in comparison to untrained lac-growers for all the three hosts, viz. palas (Butea monosperma), ber (Zizyphus mauritiana) and kusum (Schleichera oleosa). A significant shift from lower production group to higher production group has been observed by trained lac-growers. The share of lac income in total income has increased in the case of trained lac-growers from 18.5 per cent to 24.0 per cent. More employment generation and increase in net returns have been found in lac cultivation on all the three hosts for trained lac-growers. Higher level of broodlac (seed) production has resulted in self-sufficiency in broodlac and more utilization of host trees for lac cultivation. Higher BC ratio and reduction in cost of production of broodlac and sticklac have been found in trained than untrained lac-growers for lac cultivation on all the three hosts. The study has emphasized on the need of strengthening and widening the extension activity to empower the lac growers with scientific knowledge on lac cultivation for increasing their income level.

We deduce from this classification result the complete classification of volume-preserving quasiconformal diffeomorphisms whose stable and unstable distributions are at least two dimensional. Our central idea is to take a good time change so that perodic orbits are equi-distributed with respect to a lebesgue measure.

description: The dynamics of shift among different land-use classes has been studied in the state of Jammu and Kashmir. A significant decline has been observed in the total reported area, which necessitates a proper land-use survey through remote sensing. A declining trend has also been observed in the area under forests. The unfavourable increasing trends in the area put to non-agricultural uses and barren and unculturable land are likely to have serious implications on ecological balance. Inter-sectoral land budgeting analysis has revealed that shifts in area are occurring from desirable ecological towards undesirable ecological sector. The estimates of regression analysis have revealed that the net irrigated area, literacy and area not available for cultivation have significantly improved the cropping intensity in the state agriculture, whereas agricultural density and area under rice are significant determinants of current fallow lands. The study has emphasized on the evolution of suitable institutional mechanism for scientific management, conservation and development of land resources in the state.

description: Although recent works try to improve collective communication in grid systems by separating intra and inter-cluster communication, the optimisation of communications focus only on inter-cluster communications. We believe, instead, that the overall performance of the application may be improved if intra-cluster collective communications performance is known in advance. Hence, it is important to have an accurate model of the intra-cluster collective communications, which provides the necessary evidences to tune and to predict their performance correctly. In this paper we present our experience on modelling such communication strategies. We describe and compare different implementation strategies with their communication models, evaluating the models' accuracy and describing the practical challenges that can be found when modelling collective communications.

description: The two-axes pricing policy is followed normally in the dairy business centres of Tamil Nadu. Though it is scientifically rational, it ignores the input prices, technology and government policies. For sustaining the growth momentum and achieving an annual average growth of 7-8 per cent in the next five years and considering that dairying is practised as a component of mixed farming systems, it becomes imperative to take into account the interrelationship among the enterprises and general economic factors while fixing the milk price. In this study, development of a price determination model has been reported. It is based on the cost of production and takes into account price and non-price factors, viz. technology, and projected different price scenarios of milk for the coming years. The study undertaken in the Tamil Nadu state, is based on primary data collected for the year 2002-03 and has used normalized restricted quadratic profit function analysis and price determination models. It has been found that to maintain constant returns to the production cost of milk, the milk price would need an upward adjustment of 9.97 per cent, whereas to provide constant net monetary income, the milk price would need an upward adjustment by 10.30 per cent for buffalo milk. Considering 2002-03 as the base year, the estimated price for milk per litre is expected to be Rs 23.64 at constant monetary income and Rs 23.15 at constant return to production cost in the year 2009-10. The results of the paper are illustrative of the utility approach in generating consistent price sets for milk in response to alternative policy interventions.

description: We develop a potential algorithm to relate the depth development of ultra high energy extensive air showers and the time delay for individual muons. The time distributions sampled at different positions at ground level by a large air shower array are converted into distributions of production distances using an approximate relation between production distance, transverse distance and time delay. The method is naturally restricted to inclined showers where muons dominate the signal at ground level but could be extended to vertical showers provided that the detectors used can separate the muon signal from electrons and photons. We explore the accuracy and practical uncertainties involved in the proposed method. For practical purposes only the muons that fall outside the central region of the shower can be used, and we establish cuts in transverse distance. The method is tested using simulated showers by comparing the production distance distributions obtained using the method with the actual distances in the simulated showers. It could be applied in the search of neutrinos to increase the acceptance to highly penetrating particles, as well as for unraveling the relative compositions of protons and heavy nuclei. We also illustrate that the obtained depth distributions have minimum width when both the arrival direction and the core position are well reconstructed.

description: We develop a hierarchical structure (HS) analysis for quantitative description of statistical states of spatially extended systems. Examples discussed here include an experimental reaction-diffusion system with Belousov-Zhabotinsky kinetics, the two-dimensional complex Ginzburg-Landau equation and the modified FitzHugh-Nagumon equation, which all show complex dynamics of spirals and defects. We demonstrate that the spatial-temporal fluctuation fields in the above mentioned systems all display the HS similarity property originally proposed for the study of fully developed turbulence [Z.-S. She and E. Leveque, Phys. Rev. Lett. {\bf 72}, 336 (1994)]. The derived values of a HS parameter $β$ from experimental and numerical data in various physical regimes exhibit consistent trends and characterize the degree of turbulence in the systems near the transition, and the degree of heterogeneity of multiple disorders far from the transition. It is suggested that the HS analysis offers a useful quantitative description for the complex dynamics of two-dimensional spatiotemporal patterns.

description: The baryon acoustic oscillations (BAO) provide an important bridge between the early universe and the expansion history at late times. While the BAO has primarily been used as a standard ruler, it also encodes recombination era physics, as demonstrated by a recent measurement of the neutrino-induced phase shift in the BAO feature. In principle, these measurements offer a novel window into physics at the time of baryon decoupling. However, our analytic understanding of the BAO feature is limited, particularly for the range of Fourier modes measured in surveys. As a result, it is unclear what the BAO phase teaches us about the early universe beyond what is already known from the cosmic microwave background (CMB). In this paper, we provide a more complete (semi-)analytic treatment of the BAO on observationally relevant scales. In particular, we compute corrections to the frequency and phase of the BAO feature that arise from higher order effects which occur in the tight coupling regime and during baryon decoupling. The total phase shift we find is comparable to a few percent shift in the BAO scale (frequency) and thus relevant in current data. Our results include an improved analytic calculation of the neutrino induced phase shift template that is in close agreement with the numerically determined template used in measurements of the CMB and BAO.

description: New food processing technologies are developed on a continuous basis. While food scientists may applaud the progress of science, consumers have been known to take a more conservative approach and do not always readily see the benefits of new processing methods. As learned from earlier examples (such as GM and irradiation), the advantages that a new processing technology has to offer do not necessarily guarantee the success of a product in the market place. If consumers do not perceive the benefits of a new technology as relevant, its application is threatened. For example, studies of consumer attitudes towards GM foods have found that consumer acceptance depends on whether consumers perceive specific benefits associated with the product (Frewer et al. 1996; Frewer et al. 1997). Hence, a benefit that is perceived only to be in the interest of the manufacturer is not sufficient. This paper examines consumers’ attitudes towards apple juice produced by two new food processing technologies, high-pressure processing (HPP) and pulsed electric field processing (PEF) in four European countries.2 Products produced by these technologies are soon to be introduced on the markets in Europe on a larger scale. Therefore, from a managerial point of view it is interesting to learn more about how consumers perceive food products produced by these novel processing technologies.

description: We propose a novel method to constrain the Milky Way (MW) mass $M_{\rm vir}$ with its corona temperature observations. For a given corona density profile, one can derive its temperature distribution assuming a generalized equilibrium model with non-thermal pressure support. While the derived temperature profile decreases substantially with radius, the X-ray-emission-weighted average temperature, which depends most sensitively on $M_{\rm vir}$, is quite uniform toward different sight lines, consistent with X-ray observations. For an Navarro-Frenk-White (NFW) total matter distribution, the corona density profile should be cored, and we constrain $M_{\rm vir}=(1.19$ - $2.95) \times 10^{12} M_{\rm sun}$. For a total matter distribution contributed by an NFW dark matter profile and central baryons, the corona density profile should be cuspy and $M_{\rm vir,dm}=(1.34$ - $5.44) \times 10^{12} M_{\rm sun}$. Non-thermal pressure support leads to even higher values of $M_{\rm vir}$, while a lower MW mass may be possible if the corona is accelerating outward. This method is independent of the total corona mass, its metallicity, and temperature at very large radii.

Molecular characterization of Mycobacterium tuberculosis PKNB
Creators: name: Drews, Steven Jeffrey
Publisher: name: University of British Columbia
Year: 2009

description: The Mycobacterium tuberculosis genome contains eleven genes encoding for proteinserine/ threonine kinases (PSTKs). The putative PSTK gene pknB was chosen for study because the location of this gene within the chromosome led us to suspect that pknB encodes for a protein that may control mycobacterial growth. Recombinant M. tuberculosis PknB was expressed in Eschericia coli and was shown to be a functional kinase that is autophosphorylated on serine and threonine residues during in vitro kinase assays. In vitro kinase assays also showed that PknB phosphorylates myelin basic protein (MBP). A putative pknB promoter was cloned as a transcriptional fusion to a green fluorescence protein gene (gfp) within an epichromosomal mycobacterial shuttle vector. This putative promoter was active during log phase growth in M. smegmatis cultures, with attenuated activity in stationary phase growth. Anti-PknB antibodies were used to show that M. tuberculosis PknB is a membrane-localized protein. PknB protein expression also increased during log phase growth, with maximal expression evident during stationary phase growth. Attempts to knock out the pknB gene within M. tuberculosis H37Rv were unsuccessful due to a very low efficiency of electroporation and illegitimate recombination of the knock out construct. The pSJD202 vector was constructed by cloning pknB, with its putative promoter, into the integrative vector pGint. M. tuberculosis strains containing pSJD202 grew faster and produced relatively more PknB than pGINT strains. On-going experiments in our laboratory will use the anti-PknB antibodies as well as the pSJD202 vector as tools for future pknB disruption. The protein kinase inhibitor l-(5-isoquinolinesulfonyl)-2-methylpiperazine (H7) inhibited the growth of both the slow growing Mycobacterium bovis BCG, and the fast-growing saprophyte M. smegmatis mc 155, in a dose dependent manner. Furthermore, micromolar concentrations of H7 compound induced a significant decrease in the activity of the Mycobacterium tuberculosis protein-serine/threonine kinase (PSTK) PknB. This thesis outlines a variety of approaches used to study the function of pknB as well as other kinases of M. tuberculosis. The combination of information gained in these experiments provides a picture of PknB as a membrane-associated PSTK that is differentially expressed during mycobacterial growth and may play a role in both cell wall biosynthesis and growth.

Bubbles with a rich dynamical behaviour are observed depending on the topological properties of the heterogeneity. The linear stability analysis of soliton-bubbles predicts the formation of oscillating bubbles and the insertion of new bubbles inside an expanding precursor bubble. Numerical simulations in 2+1 dimensions are in good agreement with theoretical predictions.

description: We provide a discussion of the density and photoexcitation sensitivity of the X-ray spectra of Fe L-shell ions (Fe XVII-Fe XXIV) calculated with the Livermore X-ray Spectral Synthesizer, a suite of IDL codes that calculates spectral models of highly charged ions based primarily on HULLAC atomic data. These models are applicable to collisionally ionized laboratory or cosmic plasmas with electron temperatures T_e ~ 2-45 MK (0.2-4 keV) and electron densities n_e > 1E11 cm^{-3}. Potentially useful density diagnostics are identified for Fe XVII and Fe XIX-Fe XXIII, with the most straightforward being the Fe XVII I(17.10 A)/I(17.05 A) line ratio and the Fe XXII I(11.92 A)/I(11.77 A) line ratio. Applying these models to the Chandra X-ray Observatory High Energy Transmission Grating spectrum of the intermediate polar EX Hya, we find that the strength of all the Fe L-shell lines are consistent with electron densities n_e > 1E14 cm^{-3}. Specifically, from the observed Fe XVII I(17.10 A)/I(17.05 A) line ratio, we infer an electron density n_e > 2E14 cm^{-3} at the 3 sigma level, while from the observed Fe XXII I(11.92 A)/I(11.77 A) line ratio, we infer n_e = 1.0^{+2.0}_{-0.5}E14 cm^{-3} at the 1 sigma level and n_e > 2E13 cm^{-3} at the 3 sigma level.

description: In this article we analysed the role of acceptance of a new food within innovation processes in the Italian food sector. Our analysis focused on preferences and the opinions expressed by three distinct groups of young consumers in relation to functional foods (FFs). Such products represent an innovation both in terms of technology and commerce for Italian food companies, and the segment of young consumers would appear especially interested in them. Our results showed that a different cultural education, hence the degree of knowledge cumulated by young consumers, is a key element in the preference for, and perception of FFs. This implies the need to identify highly differentiated marketing strategies for firms seeking to reach this segment of FF demand in Italy.

description: In the rapid cycling synchrotron of the China Spallation Neutron Source, the anti-correlated painting was adopted for the design scheme of the injection system. In the beam commissioning, with the optimization of the anti-correlated painting,the injection beam loss has been well controlled and the injection efficiency has exceeded 99%. Combined with other aspects of adjustments, the beam power on the target has reached 50 kW smoothly. In this paper, we have studied the injection optimization in the beam commissioning. Compared to the simulation results of the design scheme, the transverse beam distribution, transverse coupling effect and beam loss of the anti-correlated painting in the beam commissioning are somewhat different. Through the machine studies, we have carefully analyzed these differences and studied their reasons.

description: Consumer demand in relation to food is increasingly shifting towards products that are safe, nutritious, and of good eating quality. Beef consumers are demanding for experience quality that matches their quality expectations formed prior to consumption, particularly with respect to beef tenderness. The development of a beef quality guarantee system, backed up by objective knowledge obtained through muscle profiling research, can allow the beef industry to meet these consumer demands. A qualitative consumer study has been carried out to assess European consumers’ opinions about beef quality and beef related technologies. This paper reports on consumer opinions and perceptions about muscle profiling and a beef quality guarantee system. Findings indicate that both concepts are well accepted by European beef consumers, although not unconditional. The insights obtained from this study indicate good opportunities for the development of a beef quality guarantee system in Europe. As an increase in consumers’ satisfaction with beef products could lead to higher consumption rates and industry profitability, the introduction of a quality guarantee system can contribute to further market development and improved competitiveness of the European beef industry.

description: D3.1.14 E-learning module ‘Nutrient analysis for non-chemists’

Summary

The first case ‘fat & fatty acids’ of the e-learning module on “Nutrient analysis for non-chemists” has been field tested and evaluated by the participants of the EuroFIR Food Composition Course in Bratislava in October 2008. The overall rating of the whole module was marked 4.4 (on a scale of 1-5); the visual aspects were rated 4.5 and the English language was clear and understandable for 92% of the participants. The comments and experiences from these participants will be used to further improve and optimise the following cases in the module (annex 1). The progress of the first case on Fats & Fatty acids has been shown electronically at the SMB meeting in Prague. The development of the first case took longer than predicted; the other cases on protein and carbohydrates & minerals were finalised in 2009. In 2009 the final prototype was presented in Vienna at the annual meeting of EuroFIR and at the ICN in Bangkok in October 2009. In 2010 the e-learning module will be installed at the new EuroFIR website and will become available for the EuroFIR partners and EuroFIR AISBL members.

description: We show that a spontaneous strain and spontaneous magnetization can arise in the doped topological insulators with a two-component superconducting vector order parameter. The details of the effects crucially depend on the symmetry of the superconducting order parameter, whether it is nematic or chiral. The transition from the nematic state to the chiral one can be performed by application of a magnetic field while the transition from the chiral state to the nematic one is tuned by the external strain. These transitions associated with a jump of the magnetic susceptibility and mechanical stiffness. Possible experimental observations of the predicted effects are discussed.

description: Irrigation with raw or diluted wastewater is a widespread phenomenon, occurring on 20 million hectares across the developing world, especially in Asian countries, but also in peri-urban areas around almost every city of sub-Saharan Africa and in many Latin American cities. Growing urban populations and consequent increases in demand for food and water has spurred the use of sewage to water crops as this is, in many cases, the only form of irrigation for farmers who either lack clean water or for whom clean water is too expensive. Wastewater has high nutrient value and constitutes a reliable source (Scott et al., 2004). It is mostly used to produce cash crops (e.g. vegetables and cereals). For example, it has been estimated that in most parts of Sub- Saharan Africa, urban and peri-urban farms irrigated with polluted water resources contribute 60-100 percent of the vegetables needed in most cities (IFPRI, 2008). Production of these cash crops is found to generate significant livelihood opportunities, not only for urban and peri-urban farmers but also for traders, input suppliers and other service providers (Scott et al., 2004; Water Policy Briefing, 2006).
