Economic analysis of integrated farming systems in the Kuttanad region of Kerala state, India: A case study

Agriculture, with its allied sectors, is unquestionably the largest livelihood provider in India. According to Committee on Doubling of Farmers’ Income Report, the average annual earning of a small and marginal farmer household was Rs 79,779 in 2015-16 and indicates that 86% of farmer households earn only 9% of total income and rest of the farmers earn 91% of total income. Integrated farming system practised mostly by small and marginal farmers, is a viable option for increasing farm income. The present study was undertaken to identify the farming systems practised by small and marginal holdings in Kuttanad region of Kerala state, India and also attempts to assess the profitability of these farms and suggest optimal farm plans using linear programming technique. The study revealed that rice + fish and Coconut + Banana+ Dairy cow + Poultry+ Goat were the most profitable farming systems with a benefit cost ratio of 2.63 and 2.86, respectively. The resource allocation in the existing plan was sub-optimal. The optimisation of resource use led to maximization of net returns, indicating the potential for realising greater income. The net returns of rice + fish increased from Rs. 181724 to Rs. 220010 in the optimal plan. The study also suggests the extent to which net returns can be increased with additional units of constraint resources viz., land/labour. The net returns in FS IV can be increased by Rs.286177.9 per additional acreage of land allotted.  Thus, the farmers in Kuttanad can increase their income by optimal resource allocation and by deploying additional units of land or labour

India’s trade potential and export opportunities for spices

Economic growth and development of a country rely on trade as it serves as a driving force with efficient utilization of factor of endowments. Several commodities are traded world-wide, among them spices which has a long history of being one of the highly traded commodity. Developing countries including India are the leading producer and exporter of spices in the world. The demand for Indian spices has gone up in the United States of America, Vietnam, United Arab Emirates, United Kingdom, etc. The study assess the comparative advantage of major spices exporting countries for pepper, cardamom and turmeric-based on data available in International Trade Centre. To analyse the effect of trade liberalisation, a simulation model (SMART) developed by UNCTAD was used to estimate trade creation, diversion and revenue effect on importing and exporting countries. The result shows that India has a comparative advantage in the export of Turmeric, Guatemala in Cardamom and Vietnam in Pepper. The impact of tariff relief on India has greater advantage, which has trade creation in the export of cardamom and turmeric. Whereas in pepper, comparatively, trade diversion is higher than trade creation, indicating that less efficient countries are given a chance to export to the top importing countries due to a reduction in tariff. Indian spice exporters should focus on promoting or exporting spices to countries like Netherlands, United States, United Kingdom, and Germany

A Review On Hadoop: Privacy For A Multi-Skyline Queries With Map Reduce

The significance of skyline  brings about numerous applications, for example, multi-criteria basic leadership, information mining, and data prescribed frameworks. Horizon inquiries are valuable for finding intriguing tuples from an extensive informational collection as indicated by different criteria. The sizes of informational collections are always expanding and the design of back-closes are changing from single-hub situations to non-traditional ideal models like MapReduce The horizon administrator has pulled in impressive consideration as of late because of its wide applications. In any case, processing a horizon is testing today since we need to manage huge information. For information concentrated applications, the MapReduce structure has been broadly utilized as of late. In this paper, also, we apply the strength control sifting technique to adequately prune non-horizon focuses ahead of time. We next parcel information in light of the areas separated by the quad tree and process competitor horizon focuses for each segment utilizing MapReduce.   At long last, MapReduce Grid Partitioning based Single-Reducer Skyline Computation (MR-GPSRS) utilizes a solitary reducer to amass the neighborhood horizons properly to figure the worldwide horizon. Conversely, MapReduce Grid Partitioning based Multiple Reducer Skyline Computation (MR-GPMRS) additionally separates neighborhood horizons and disperses them to different reducers that process the worldwide horizon in a free and parallel way. The proposed calculations are assessed through broad analyses, and the outcomes demonstrate that MR-GPMRS fundamentally beats the choices in different settings. we propose an effective technique for preparing multi-horizon inquiries with MapReduce with no alteration of the Hadoop internals. Through different analyses, we demonstrate that our approach beats past examinations by requests of extent

Physiological Studies of Chlorobiaceae Suggest that Bacillithiol Derivatives Are the Most Widespread Thiols in Bacteria

Low-molecular-weight (LMW) thiols mediate redox homeostasis and the detoxification of chemical stressors. Despite their essential functions, the distribution of LMW thiols across cellular life has not yet been defined. LMW thiols are also thought to play a central role in sulfur oxidation pathways in phototrophic bacteria, including the Chlorobiaceae. Here we show that Chlorobaculum tepidum synthesizes a novel LMW thiol with a mass of 412 ± 1 Da corresponding to a molecular formula of C14H24N2O10S, which suggests that the new LMW thiol is closely related to bacillithiol (BSH), the major LMW thiol of low-G+C Gram-positive bacteria. The Cba. tepidum LMW thiol structure was N-methyl-bacillithiol (N-Me-BSH), methylated on the cysteine nitrogen, the fourth instance of this modification in metabolism. Orthologs of bacillithiol biosynthetic genes in the Cba. tepidum genome and the CT1040 gene product, N-Me-BSH synthase, were required for N-Me-BSH synthesis. N-Me-BSH was found in all Chlorobiaceae examined as well as Polaribacter sp. strain MED152, a member of the Bacteroidetes. A comparative genomic analysis indicated that BSH/N-Me-BSH is synthesized not only by members of the Chlorobiaceae, Bacteroidetes, Deinococcus-Thermus, and Firmicutes but also by Acidobacteria, Chlamydiae, Gemmatimonadetes, and Proteobacteria. Thus, BSH and derivatives appear to be the most broadly distributed LMW thiols in biology

Performance characteristics of an instrument-free point-of-care CD4 test (VISITECTVR CD4) for use in resource-limited settings

Objective: CD4þ T lymphocyte count remains the most common biomarker of immune status and disease progression in human immunodeficiency virus (HIV)-positive individuals. VISITECTVR CD4 is an instrument-free, low-cost point-of-care CD4 test with a cut-off of 350 CD4 cells/lL. This study aimed to evaluate VISITECTVR CD4 test’s diagnostic accuracy. Methods: Two hundred HIV-positive patients attending a tertiary HIV centre in South India were recruited. Patients provided venous blood for reference and VISITECTVR CD4 tests. An additional finger-prick blood sample was obtained for VISITECTVR CD4. VISITECTVR CD4’s diagnostic performance in identifying individuals with CD4 counts 350 cells/lL was assessed by calculating sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) taking flow cytometry as the reference. Results: The overall agreement between VISITECTVR CD4 and flow cytometry was 89.5% using venous blood and 81.5% using finger-prick blood. VISITECTVR CD4 showed better performance using venous blood [sensitivity: 96.6% (95% confidence interval: 92.1%–98.9%), specificity: 70.9% (57.1%–82.4%), PPV: 89.7% (83.9%–94.0%) and NPV: 88.6% (75.4%–96.2%)] than using fingerprick blood [sensitivity: 84.8% (77.9%–90.2%), specificity: 72.7% (59.0%–83.9%), PPV: 89.1% (82.7%–93.8%) and NPV: 64.5% (51.3%–76.3%)]. Conclusion: VISITECTVR CD4 performed well using venous blood, demonstrating its potential utility in decentralization of CD4 testing services in resource-constrained settings

The results concluded that majority of the respondents purchased jaggery and sugar, cold pressed oil, snacks and millets category from the retail shops of FPOs. The quality and nutrient content were major product traits influencing consumers for purchasing the FPO food products. Most of the consumers felt that the quality and price of the food products were high in FPOs retail stores compared with other retail stores. So, FPOs should target high income people with high purchasing power who appreciate quality. Local people were purchasing the FPOs food products anytime. FPOs can devise effective marketing strategies to attract new customers from local and non-local customers. Most of the people have no awareness about FPOs retail outlets. Therefore, FPOs should pay attention in promoting their products and increasing the retail outlets for attracting the consumers and increasing the sales

Enhancement of Lutein Production in Chlorella sorokiniana (Chorophyta) by Improvement of Culture Conditions and Random Mutagenesis

Chlorella sorokiniana has been selected for lutein production, after a screening of thirteen species of microalgae, since it showed both a high content in this carotenoid and a high growth rate. The effects of several nutritional and environmental factors on cell growth and lutein accumulation have been studied. Maximal specific growth rate and lutein content were attained at 690 μmol photons m−2 s−1, 28 °C, 2 mM NaCl, 40 mM nitrate and under mixotrophic conditions. In general, optimal conditions for the growth of this strain also lead to maximal lutein productivity. High lutein yielding mutants of C. sorokiniana have been obtained by random mutagenesis, using N-methyl-N′-nitro-nitrosoguanidine (MNNG) as a mutagen and selecting mutants by their resistance to the inhibitors of the carotenogenic pathway nicotine and norflurazon. Among the mutants resistant to the herbicides, those exhibiting both high content in lutein and high growth rate were chosen. Several mutants exhibited higher contents in this carotenoid than the wild type, showing, in addition, either a similar or higher growth rate than the latter strain. The mutant MR-16 exhibited a 2.0-fold higher volumetric lutein content than that of the wild type, attaining values of 42.0 mg L−1 and mutants DMR-5 and DMR-8 attained a lutein cellular content of 7.0 mg g−1 dry weight. The high lutein yield exhibited by C. sorokiniana makes this microalga an excellent candidate for the production of this commercially interesting pigment
