Emissions from India’s transport sector: Statewise synthesis

A decentralized emission inventories are prepared for road transport sector of India in order to design and implement suitable technologies and policies for appropriate mitigation measures. Globalization and liberalization policies of the government in 90's have increased the number of road vehicles nearly 92.6% from 1980–1981 to 2003–2004. These vehicles mainly consume non-renewable fossil fuels, and are a major contributor of green house gases, particularly CO2 emission. This paper focuses on the statewise road transport emissions (CO2, CH4, CO, NOx, N2O, SO2, PM and HC), using region specific mass emission factors for each type of vehicles. The country level emissions (CO2, CH4, CO, NOx, N2O, SO2 and NMVOC) are calculated for railways, shipping and airway, based on fuel types. In India, transport sector emits an estimated 258.10 Tg of CO2, of which 94.5% was contributed by road transport (2003–2004). Among all the states and Union Territories, Maharashtra's contribution is the largest, 28.85 Tg (11.8%) of CO2, followed by Tamil Nadu 26.41 Tg (10.8%), Gujarat 23.31 Tg (9.6%), Uttar Pradesh 17.42 Tg (7.1%), Rajasthan 15.17 Tg (6.22%) and, Karnataka 15.09 Tg (6.19%). These six states account for 51.8% of the CO2 emissions from road transport.

Total Factor Productivity in Indian Electronic Sector after Liberalisation: Sources and Outcomes

This paper analyses the efficiency and productivity growth of the Electronic Sector of India in the liberalization era since 1991. The study gives an insight into the process of the growth of one of the most upcoming sector of this decade. This sector has experienced a vast structural change along with the changing economic structures in India after liberalisation. With the opening up of this sector to foreign market and incoming of multinational companies, the environment has become highly competitive. The law that operates is that of Darwin’s ‘Survival of the fittest’. Existing industries experience a continuous threat of exit due to entrance of new potential entrants. Thus, it becomes inevitable for the existing industries in this sector to improve productivity growth for their survival. It is thus important to analyze how the industries in this sector have performed over the years and what are the factors that have contributed to the overall output growth.

Precision and long-term stability of clumped-isotope analysis of CO2 using a small-sector isotope ratio mass spectrometer

RATIONALE The ratio of the measured abundance of 13C18O bonding CO2 to its stochastic abundance, prescribed by the delta 13C and delta 18O values from a carbonate mineral, is sensitive to its growth temperature. Recently, clumped-isotope thermometry, which uses this ratio, has been adopted as a new tool to elucidate paleotemperatures quantitatively. METHODS Clumped isotopes in CO2 were measured with a small-sector isotope ratio mass spectrometer. CO2 samples digested from several kinds of calcium carbonates by phosphoric acid at 25 degrees C were purified using both cryogenic and gas-chromatographic separations, and their isotopic composition (delta 13C, delta 18O, Delta 47, Delta 48 and Delta 49 values) were then determined using a dual-inlet Delta XP mass spectrometer. RESULTS The internal precisions of the single gas Delta 47 measurements were 0.005 and 0.02 parts per thousand (1 SE) for the optimum and the routine analytical conditions, respectively, which are comparable with those obtained using a MAT 253 mass spectrometer. The long-term variations in the Delta 47 values for the in-house working standard and the heated CO2 gases since 2007 were close to the routine, single gas uncertainty while showing seasonal-like periodicities with a decreasing trend. Unlike the MAT 253, the Delta XP did not show any significant relationship between the Delta 47 and delta 47 values. CONCLUSIONS The Delta XP gave results that were approximately as precise as those of the MAT 253 for clumped-isotope analysis. The temporal stability of the Delta XP seemed to be lower, although an advantage of the Delta XP was that no dependency of delta 47 on Delta 47 was found. Copyright (c) 2012 John Wiley & Sons, Ltd.

Corporate social responsibilities of Indian public sector enterprises-a case study of Bharat Heavy Electricals Limited (BHEL)

The high level of public accountability attached to Public Sector Enterprises as a result of public ownership makes them socially responsible. The Committee of Public Undertakings in 1992 examined the issue relating to social obligations of Central Public Sector Enterprises and observed that ``being part of the `State', every Public Sector enterprise has a moral responsibility to play an active role in discharging the social obligations endowed on a welfare state, subject to the financial health of the enterprise''. It issued the Corporate Social Responsibility Guidelines in 2010 where all Central Public Enterprises, through a Board Resolution, are mandated to create a CSR budget as a specified percentage of net profit of the previous year. This paper examines the CSR activities of the biggest engineering public sector organization in India, Bharath Heavy Electricals Limited. The objectives are twofold, one, to develop a case study of the organization about the funds allocated and utilized for various CSR activities, and two, to examine its status with regard to other organizations, the 2010 guidelines, and the local socio-economic development. Secondary data analysis results show three interesting trends. One, it reveals increasing organizational social orientation with the formal guidelines in place. Two, Firms can no longer continue to exploit environmental resources and escape from their responsibilities by acting separate entities regardless of the interest of the society and Three the thrust of CSR in public sector is on inclusive growth, sustainable development and capacity building with due attention to the socio-economic needs of the neglected and marginalized sections of the society.

On existence of periodic solutions for stable interval plants with odd, sector type nonlinearities

In several systems, the physical parameters of the system vary over time or operating points. A popular way of representing such plants with structured or parametric uncertainties is by means of interval polynomials. However, ensuring the stability of such systems is a robust control problem. Fortunately, Kharitonov's theorem enables the analysis of such interval plants and also provides tools for design of robust controllers in such cases. The present paper considers one such case, where the interval plant is connected with a timeinvariant, static, odd, sector type nonlinearity in its feedback path. This paper provides necessary conditions for the existence of self sustaining periodic oscillations in such interval plants, and indicates a possible design algorithm to avoid such periodic solutions or limit cycles. The describing function technique is used to approximate the nonlinearity and subsequently arrive at the results. Furthermore, the value set approach, along with Mikhailov conditions, are resorted to in providing graphical techniques for the derivation of the conditions and subsequent design algorithm of the controller.

Co-benefits, trade-offs, barriers and policies for greenhouse gas mitigation in the agriculture, forestry and other land use (AFOLU) sector

The agriculture, forestry and other land use (AFOLU) sector is responsible for approximately 25% of anthropogenic GHG emissions mainly from deforestation and agricultural emissions from livestock, soil and nutrient management. Mitigation from the sector is thus extremely important in meeting emission reduction targets. The sector offers a variety of cost-competitive mitigation options with most analyses indicating a decline in emissions largely due to decreasing deforestation rates. Sustainability criteria are needed to guide development and implementation of AFOLU mitigation measures with particular focus on multifunctional systems that allow the delivery of multiple services from land. It is striking that almost all of the positive and negative impacts, opportunities and barriers are context specific, precluding generic statements about which AFOLU mitigation measures have the greatest promise at a global scale. This finding underlines the importance of considering each mitigation strategy on a case-by-case basis, systemic effects when implementing mitigation options on the national scale, and suggests that policies need to be flexible enough to allow such assessments. National and international agricultural and forest (climate) policies have the potential to alter the opportunity costs of specific land uses in ways that increase opportunities or barriers for attaining climate change mitigation goals. Policies governing practices in agriculture and in forest conservation and management need to account for both effective mitigation and adaptation and can help to orient practices in agriculture and in forestry towards global sharing of innovative technologies for the efficient use of land resources. Different policy instruments, especially economic incentives and regulatory approaches, are currently being applied however, for its successful implementation it is critical to understand how land-use decisions are made and how new social, political and economic forces in the future will influence this process.

Status of the MSSM Higgs sector using global analysis and direct search bounds, and future prospects at the High Luminosity LHC

In this paper, we search for the regions of the phenomenological minimal supersymmetric standard model (pMSSM) parameter space where one can expect to have moderate Higgs mixing angle (alpha) with relatively light (up to 600 GeV) additional Higgses after satisfying the current LHC data. We perform a global fit analysis using most updated data (till December 2014) from the LHC and Tevatron experiments. The constraints coming from the precision measurements of the rare b-decays B-s -> mu(+)mu(-) and b -> s gamma are also considered. We find that low M-A(less than or similar to 350) and high tan beta(greater than or similar to 25) regions are disfavored by the combined effect of the global analysis and flavor data. However, regions with Higgs mixing angle alpha similar to 0.1-0.8 are still allowed by the current data. We then study the existing direct search bounds on the heavy scalar/pseudoscalar (H/A) and charged Higgs boson (H-+/-) masses and branchings at the LHC. It has been found that regions with low to moderate values of tan beta with light additional Higgses (mass <= 600 GeV) are unconstrained by the data, while the regions with tan beta > 20 are excluded considering the direct search bounds by the LHC-8 data. The possibility to probe the region with tan beta <= 20 at the high luminosity run of LHC are also discussed, giving special attention to the H -> hh, H/A -> t (t) over bar and H/A -> tau(+)tau(-) decay modes.

Diagnostico situacional del sector de pequeños y medianos productores avícolas de huevos de mesa en Nicaragua

En Nicaragua, la producción de huevos experimentó un crecimiento anual del 8% al cierre del año 2012, se espera que para el año 2013 sea superado. La avicultura aporta 2.8% al PIB nacional y 30% al PIB agropecuario. El consumo per cápita de huevos es de 86. No existe en Nicaragua una clasificación oficial del sector avícola de huevos debido a que no ha sido creada por ninguna entidad gubernamental concerniente. Cada actor relacionado con el sector avícola posee una apreciación particular sobre la clasificación; el parámetro con mayor coincidencia es el número de aves en explotación. La avicultura se divide en dos sectores: ANAPA y el sector de pequeños y medianos avicultores de huevos; este último está representado por tres organizaciones: APEMEPAN, UNAPA y COOMPAS. La mayoría de los pequeños y medianos avicultores del país están concentrados en la región del Pacífico con un 88.06% del total de las granjas de los avicultores de huevos de mesa. La avicultura de pequeños y medianos productores de huevos carece de una cadena productiva integrada, la mayoría no cuentan con una planta procesadora de alimentos ni con canales de distribución propios, carecen de plantas incubadoras destinadas para aves ponedoras. Además, el sector de pequeños y medianos avicultores del país posee costos de producción altos, un nivel tecnológico bajo, acceso a capacitación y asistencia técnica escaso, acceso al financiamiento es considerado poco flexible por avicultores; además, afirman que no existen políticas de apoyo al sector; sin embargo en el desarrollo de este estudio se reveló la existencia de ciertas políticas y programas de apoyo principalmente en ministerios como MEFCCA, MIFIC y MAGFOR. Históricamente no ha existido exportación de huevos en Nicaragua y hubo importaciones sólo en el año 2011; actualmente los avicultores afirman la existencia de importaciones ilegales de huevos de procedencia hondureña.

Caracterización del manejo zootécnico del cerdo criollo (Sus scrofa domesticus) en el área rural del municipio de Río Blanco, Matagalpa, 2013

El cerdo fue introducido a Nicaragua en el año 1493, durante el segundo viaje que Cristóbal Colón realizara a América durante la colonización española. La crianza de cerdo de traspatio en el país juega un rol importante en la economía de las familias rural es, siendo característica la presencia de animales criollos. Estos animales representan un recurso adaptado a condiciones adversas de crianza. El presente trabajo se realizó en el municipio de Río Blanco departamento de Matagalpa, con el objetivo de caracterizar el manejo zootécnico del cerdo criollo. Para recabar la información se diseñó un instrumento con preguntas abiertas y cerradas (encuesta) que incluyó los componentes: socioeconómico, alimentación, salud, genética , producción y reproducción, mediante un sondeo previo. Se realizaron entrevistas al nivel de tod o el sector rural del municipio, utilizando el criterio de selección de la cría de al menos 3 cerdos, las comunidades incluidas fueron un total de 20 con un total de 68 productores y se registrar con 548 cerdos. Del total de productores el 52.94% de encuestados eran mujeres y el 47.05% eran hombres, con un promedio de edad de 43.73 años; según el estudio, el papel de la mujer en la actividad de crianza de cerdos criollos en la zona rural es impactante, pues alcanza el 98% como principal ocupación. En lo que respecta a la alimentación de los cerdos en el municipio , esta tiene como base granos básicos, tubérculos y musáceas, además de los desperdicios de cocina. La base genética de los cerdos en el municipio está constituida principalmente por grupos raciales de animales criollos con características diversas en cuanto a su exterior. Según los productores en el último año se registró un 39. 71% de muertes, mientras que el 60. 29 afirmó lo contrario, el 34. 37% de muertes ocurre por trastornos de la salud, un 34 . 37% por causas desconocidas, un 21. 87% por plastamientos y un 9. 37% por diarrea. Las categorías de cerdos lactantes y en desarrollo son las más propensas a trastornos de la salud con un 56% cada un a, la categoría de cerdos en crecimiento con un 32%, cerdas adultas y engorde con 24% y cerdos adultos con 16%. En las cerdas reproductoras se estimó según la información brindada, que incorporan a la cerda hacia los 6.51 meses, obteniendo un promedio de 1. 87 partos por año, con una prolificidad de 8.11 cerditos por camada con una viabilidad del 88.26% que equivale a 7. 16 cerditos por camada al destete. De manera general, se observó que para mejorar la producción de cerdos en la zona, no es necesario reemplazar totalmente a los cerdos criollos por razas mejoradas, sino que hay que mejorar las condiciones de crianza y manejo que hasta el momento se les ofrece
