    The energetics of the wheat crop on rainfed farms have been worked out and compared with the farms having canal and tube well irrigation. A survey was conducted to investigate the pattern of energy used in production of wheat. The information was recorded from selected farms through biweekly visits. Results indicated that the farmers on bullock operated farms used more family labour than tractor operated farms, whereas, farmers on tractor operated farms used more casual labour. Bullocks were main source of power for all farms operations on bullock operated farms, however, threshing was performed with tractor driven threshers on almost all farms. Farmers on tube well irrigated farms used maximum energy to irrigate their crop.(author)

  2. The sustainability of changes in agricultural technology: The carbon, economic and labour implications of mechanisation and synthetic fertiliser use.

    Gathorne-Hardy, Alfred

    2016-12-01

    New agricultural technologies bring multiple impacts which are hard to predict. Two changes taking place in Indian agriculture are a transition from bullocks to tractors and an associated replacement of manure with synthetic fertilisers. This paper uses primary data to model social, environmental and economic impacts of these transitions in South India. It compares ploughing by bullocks or tractors and the provision of nitrogen from manure or synthetic urea for irrigated rice from the greenhouse gas (GHG), economic and labour perspective. Tractors plough nine times faster than bullocks, use substantially less labour, with no significant difference in GHG emissions. Tractors are twice as costly as bullocks yet remain more popular to hire. The GHG emissions from manure-N paddy are 30 % higher than for urea-N, largely due to the organic matter in manure driving methane emissions. Labour use is significantly higher for manure, and the gender balance is more equal. Manure is substantially more expensive as a source of nutrients compared to synthetic nutrients, yet remains popular when available. This paper demonstrates the need to take a broad approach to analysing the sustainability impacts of new technologies, as trade-offs between different metrics are common.

    2001-01-01

    Pinhole aperture point backlighter (PAPBL) imaging has been used on experiments on Omega, but results have been compromised by large backgrounds. This technique has advantages over traditional area backlighting/pinhole imaging, and the Omega experiments could benefit from this capability, but Omega time is expensive and not the place for developing diagnostic techniques if they can be developed on Trident instead. PAPBL, shot from Direct Drive Cylinder Mix experiments on Omega (DDCYLMIX 00-1, January 18 and 19, 2000). (See LA-UR-00-4187, Post-Shot Report, Direct Drive Cylinder Mix). In this campaign, they used Trident to obtain clean PAPBL images. Having accomplished that, they attempted to replicate the noise environment of Omega by producing hot electrons and having them impinge on material to produce high-energy x-rays similar to those that might be produced by hot electrons impinging on diagnostics or target positioner components on Omega. Backlighter target design was based, to some degree, on that shown by Bullock et al. at the 42nd Annual APS-DPP Meeting in Quebec City, Quebec, Canada, October 23-27, 2000. (A.B. Bullock et al., Bull. Am. Phys. Soc. 45,(7) 359 (2000); A.B. Bullock et al., Rev. Sci. Instrum. 72, 690 (2001).) We accomplished this to some degree and then attempted, with some success, to obtain a good PAPBL image in the presence of this noise. Results of this work suggest methods that might reduce the background noise in Omega PAPBL images. The goals are to obtain a pinhole aperture point backlighter (PAPBL) image on Trident and develop a method to simulate the high-energy background contribution to PAPBL imnages seen on Omega experients in order to allow future experiments to optimize signal-to-noise in PAPBL imaging.

  18. Impact of chashma right-canal on energy-inputs and crop production in dera ismail khan

    Khan, M.A.; Rehman, A.; Singh, G.

    2005-01-01

    The main objective of the present study was to investigate the patterns of energy-consumption and their relationship with crop-production and poverty-alleviation of the farming community, before and after the completion of Chashma Right-Bank Canal (CRBC) Project. A survey was made of daily inputs of energy for crop-production operations on more than 60 crop plots of 10 farms in three villages. The selection of farms in the villages was based on the financial condition of the farmers, as judged by the main power-source (bullock or tractor) that the farmer uses on his farm. Sources of energy recorded on biweekly basis were: human labor, bullocks and tractors. Crops-yields and values of output were recorded. Energy-inputs were computed on per hectare basis by summing the energy inputs to all crop-plots. Results indicated that the use of tractors does result in a reduction of human labor-hours and bullock-energy on per hectare basis. Due to lack of a permanent source of irrigation (crops were dependent on rain and floodwater), the crop-yield in the study areas was low before CRBC improvement work. Moreover, floods also damaged the crops on some plots before harvesting; therefore the consumption of energy on both bullock-operated farms (BOF) and Tractor-Operated Farms (TOF) was very low in the 1992-93 year. Post CRBC project, during 1997-98 and 2000-2001, the farms used more energy. In 1997-98, TOF obtained higher wheat-yields than BOF. However, in 2000-2001, both BOF and TOF were using tractors as their main power source, which indirectly indicated a reduction 'in poverty. As the yields and therefore crop-values were higher on TOF than BOF, the TOF obtained higher gross margins. Cost of production was low in 1992-93, but the crop-values were also low, so the gross margins remained low. Results indicate that there will be an increase in production and a reduction in cost of production through mechanized farming, however, there will be an increase in energy

    The author's objective is to correct many of the misconceptions about India and to combat mistaken analysis. He highlights the hundreds of millions who live in poverty, the rampant corruption and the incompetence of the administration. He asserts that comparisons with China are always to the disadvantage of India, except in the field of democracy, and suggests that the Indian Space Programme is symptomatic of a wide-spread misallocation of resources. And to suggest that the traffic problems in Delhi and Mumbai are being caused by more motor vehicles is a misdiagnosis. The real cause is an increase in the number of bullock carts.

While formats vary, the key component is self-analysis of strengths and weaknesses. This article describes a nurse administrator's successful use of a PDP to progress her career from a mid-level manager position at a small, rural hospital to a senior executive level position at the USA's second largest Veterans Health Administration (VHA) facility. The PDP used VHA's eight core leadership competencies: personal mastery, systems thinking, organisational stewardship, creative thinking, technical skills, interpersonal effectiveness, flexibility, and customer service. These core competencies mirror the VHA's 360° self-assessment tool supported by the National Center for Organization Development ( US Department of Veterans Affairs 2014 ).

    Cayratia trifolia Linn. Domin Syn. Vitis trifolia (Family: Vitaceae) is commonly known as Fox grape in English; Amlabel, Ramchana in Hindi and Amlavetash in Sanskrit. It is native to India, Asia and Australia. It is a perennial climber having trifoliated leaves with 2-3 cm long petioles and ovate to oblong-ovate leaflets. Flowers are small greenish white and brown in color. Fruits are fleshy, juicy, dark purple or black, nearly spherical, about 1 cm in diameter. It is found throughout the hills in India. This perennial climber is also found in the hotter part of India from Jammu and Rajasthan to Assam extending into the peninusular India upto 600 m height. Whole plant of Cayratia trifolia has been reported to contain yellow waxy oil, steroids/terpenoids, flavonoids, tannins upon preliminary phytochemical screening. Leaves contain stilbenes (piceid, reveratrol, viniferin, ampelopsin). Stem, leaves, roots are reported to possess hydrocyanic acid, delphinidin and several flavonoids such as cyanidin is reported in the leaves. This plant also contains kaempferol, myricetin, quercetin, triterpenes and epifriedelanol. Infusion of seeds along with extract of tubers is traditionally given orally to diabetic patients to check sugar level of blood. Paste of tuberous is applied on the affected part in the treatment of snake bite. Whole plant is used as diuretic, in tumors, neuralgia and splenopathy. Its climbers wrapped around the neck of frantic bullock and poultice of leaves are used to yoke sores of bullock. The bark extract shows the antiviral, antibacterial, antiprotozoal, hypoglycemic, anticancer and diuretic activity. This article focuses on the upgraded review on chemical and biological properties of Cayratia trifolia Linn. and triggers further investigation on this plant.

    Full Text Available Soil organic matter accumulation provides benefits to soil productivity and reduces atmospheric carbon concentration. However, little is known about the accumulation of C and N by sandy soils under perennial irrigated crops in semiarid regions. The objective of this study was to evaluate the effect of irrigated fruit orchard cultivation on the stocks of soil organic carbon (SOC and total nitrogen (N of an Arenosol/Quartzpsament from Paraipaba-CE, Semiarid Brazil. Soil samples were taken from irrigated orchards of banana (Musa ssp., cashew (Anacardium ocidentale, guava (Psidium guajava, bullock's heart (Annona reticulata, mango (Mangifera indica, and sapote (Manilkara zapota in the wetted-bulb and non-irrigated area between the plant rows. Additional samples were collected from adjacent areas under secondary Caatinga forest, and under a 2-year-old deforested area. Sampling depths were: 0-0.1, 0.1-0.2, and 0.2-0.4 m. The highest contents of SOC and N were found in the surface layer. The soil bulk density did not change in depth. The stocks of SOC and total N under secondary forest at 0-0.40 m layer were 27.6 and 2.4 Mg ha-1, respectively. Caatinga Forest conversion into fruit orchard cultivation led to a decrease of 5 to 23% and 4 to 21% on SOC and N stocks, respectively. Compared to other soil uses, sapote and bullock's heart contributed for a lower decrease of SOC and N stocks after deforestation. Guava, bullock's heart, mango and sapote contributed for improving the SOC stratification index.O acúmulo de matéria orgânica beneficia a produtividade do solo e reduz a concentração do carbono atmosférico.

    Auditory evoked potentials (AEP) were first used to examine hearing in elasmobranchs by Corwin and Bullock in the late 1970s and early 1980s, marking the first time AEPs had been measured in fishes. Results of these experiments identified the regions of the ear and brain in which sound is processed, though no actual hearing thresholds were measured. Those initial experiments provided the ground work for future AEP experiments to measure fish hearing abilities in a manner that is much faster and more convenient than classical conditioning. Data will be presented on recent experiments in which AEPs were used to measure the hearing thresholds of two species of elasmobranchs: the nurse shark, Ginglymostoma cirratum, and the yellow stingray, Urobatis jamaicencis. Audiograms were analyzed and compared to previously published audiograms obtained using classical conditioning with results indicating that hearing thresholds were similar for the two methods. These data suggest that AEP testing is a viable option when measuring hearing in elasmobranchs and can increase the speed in which future hearing measurements can be obtained.

    Mines Rescue teams in the 1991 E.K. Healy cup competition handled an underground exercise based on the Moura No. 4 colliery explosion which killed 12 miners on July 16, 1986. The contest organisers and hosts went to great lengths to achieve realism. This included underground water barriers and ventilation tubes being tossed around, meat, offal and bullock's blood being strewn and using trickel dusters to produce a smoke effect restricting visibility to 20 metres. The other exercises in the contest were: a theory test; and exercise involving gas monitoring, power isolation and fire fighting; and a first aid section dealt with an electrical accident near water. The task in the underground exercise was to retrieve information. The Chairman of the Assessors reported that the theory and fire fighting were handled fairly well. Handling of the electrical incident was not too bad, with the life saving techniques being very well done. The underground exercise revealed different ways of gathering information. While leadership styles and team member interaction varied this was not detrimental to efficiency. 9 photos.

    Annona reticulata Linn. (Common name: Bullock's-heart) (Annonaceae family) is a semi-evergreen and small deciduous tree. The extracts of various parts of Annona reticulata L. have been reported as cytotoxic to many cancer cells. Annona reticulata L. leaves' methanolic extract (ARME) was prepared and used against the breast cancer cells. The breast cancer cells (T-47D) viability and IC50 were evaluated by Vybrant® MTT Cell Proliferation Assay Kit. Detection of phosphatidylserine on membranes of apoptotic cells was done by Attune flow cytometer. RNA transcripts were quantified in ARME treated and untreated cells. Finally, the Vybrant® FAM Poly Caspases assay kit was used for analysis of polycaspases activity in T-47D cells. The IC50 (5 ± 0.5 µg/mL) of the ARME was found against breast cancer cells (T-47D). The Paclitaxel was used as a control standard drug for the study. The downregulation of Bcl-2 and upregulation of Bax and Bak, and caspases activation suggested induction of apoptosis in T-47D cells by ARME through mitochondrial pathway. The cell cycle halted at G2/M phase in the ARME treated cells. The ARME was found to be effective against Breast cancer cells (T-47D).

    Published information is scanty on the response of crops in mixed cropping systems to the various tillage systems practised by farmers in the northern savanna zone of Ghana. A field experiment assessed the yield and nitrogen (N) fixation of cowpea (Vigna unguiculata (L.) Walp) intercropped with maize (Zea mays L.) on four different tillage systems at Nyankpala in the Northern Region of Ghana. The experiment was laid in a split-plot design with four replications. The main factor was tillage systems comprising conventional (Con), bullock plough (BP), hand hoe (HH) and zero tillage (ZT). The sub-factor was cropping systems (CRPSYT) which consisted of sole maize, sole cowpea, maize/cowpea inter-row cropping system, and bare fallow in 2000. The last named was replaced by maize/cowpea intra-row cropping system in 2001. The results showed that Con and BP, which produced over 10 cm plough depth, significantly reduced soil bulk density that favoured significant (P I). The LERs ranged from 1.43 to 1.79 in 2000, and from 1.23 to 1.24 in 2001 for Con and ZT, respectively. These indicate 33 and 52 percent mean increases in productivity of cowpea and maize, respectively, over their pure stands across the 2 years. However, grain yields of both crops from the inter- and intra-row cropping systems were not different. (au)

    Firmiana malayana also known as "Bullocks eye or Mata Lembu" in Malaysia and can be found along riverbanks and open forests in Peninsular Malaysia and seldom planted in populated areas. The flowers of the Firmiana malayana are vivid orange in colour, on tassels up to 12 cm long. Usually this species will shed its leaves after a dry period and remains bare for six to eight weeks. The objective of this study is to determine the pollen morphological characteristics of the Firmiana malayana in order to add more information on the species under the family of Sterculiaceae in Malaysia. Methods for this study includes acetolysis technique for the pollens and viewed under light microscope and scanning electron microscope. Results shown that the pollens of the species Firmiana malayana appeared to be monad and dyad with tricolporate class with both porate and colpus present. The shape of this species is prolate with P/E index of 1.49. This species was considered as medium-size pollens as the pollens ranges from 26 - 36 µm. The ornamentation of the pollen is reticulate where the ornamentation is network-like pattern formed by exine elements of lumen and murus. Based on the results obtained, pollen morphology is a great tool that can aid in plant identification and classification as well having taxonomic values.

    Physicochemical properties and fatty acid profiles of meat from Bos indicus, Bos taurus and crossbred B. taurus×B. indicus bullocks (n=216), finished on pasture or grain, were used to estimate the effects of heterosis. Meat quality and fatty acid profiles generally benefited with crossbreeding, but the advantages from heterosis differed among finishing systems. The Warner-Bratzler shear-force in fresh and aged meat was reduced due to heterosis in pasture-finishing, but the effect was minor under grain-finishing. With pasture-finishing, heterosis caused an increase of 5% in CLA concentration, but few other changes in fatty acid profiles. In grain-finishing, heterosis caused a reduction in intramuscular fat and cholesterol, increased amounts of PUFA, n-6 fatty acids and PUFA/SFA ratio, and a decline in atherogenic index. The Δ(9) desaturase estimated activity in crossbreds showed a behavior close to B. indicus, suggesting the existence of few loci and a dominance genetic effect on enzymes involved in fatty acid synthesis and metabolism.

    We use the Bullock and Johnston suite of simulations to study the density profiles of L*-type galaxy stellar halos. Observations of the Milky Way and M31 stellar halos show contrasting results: the Milky Way has a 'broken' profile, where the density falls off more rapidly beyond ∼25 kpc, while M31 has a smooth profile out to 100 kpc with no obvious break. Simulated stellar halos, built solely by the accretion of dwarf galaxies, also exhibit this behavior: some halos have breaks, while others do not. The presence or absence of a break in the stellar halo profile can be related to the accretion history of the galaxy. We find that a break radius is strongly related to the buildup of stars at apocenters. We relate these findings to observations, and find that the 'break' in the Milky Way density profile is likely associated with a relatively early (∼6-9 Gyr ago) and massive accretion event. In contrast, the absence of a break in the M31 stellar halo profile suggests that its accreted satellites have a wide range of apocenters. Hence, it is likely that M31 has had a much more prolonged accretion history than the Milky Way.

    Full Text Available Potato is one of the most important staple foods supporting food security and livelihood to millions of marginalized and poor farmers in Nepal. Generally the smallholders’ farmers, especially those located in remote villages are inadequately informed about technical knowledge, inputs and efficient use of resources causing poor production and low productivity. Thus, the present survey aimed to examine the efficiency of resources used in potato production in Baglung District, one of the remote hilly place located in Central Himalaya. The total of 120 potato growing households was selected using simple random sampling technique from the two potato pocket in 2016. The regression coefficients of each inputs using Cobb-Douglas production function were estimated using Stata software. Our results showed that major inputs such as labor, bullock, Farm Yard Manure (FYM and intercultural operations were overused and need to decrease in terms of cost by 109, 177, 51 and 185%, respectively for its optimum allocation. Similarly, seed was found underused and need to increase its cost by 70% for optimum allocation. We concluded that inadequate training, exposure, knowledge gap and extension service to farmers in study sites were the reasons that farmers were using their resources inefficiently. It is recommended that the farmers involved in potato farming in the surveyed sites should be provided with additional proper technical knowledge for optimizing the use of resources which would help to increase the production and return from potato production.

  17. Indian draught animals power

    Full Text Available With the modernization of agriculture, the use of mechanical power in agriculture has increased but draught animal power (DAP continues to be used on Indian farms due to small holdings and hill agriculture. More than 55% of the total cultivated area is still being managed by using draught animals as against about 20% by tractors. India possessed the finest breeds of draught animals. Bullocks, buffaloes and camels are the major draught animals for field operations. Horses, mules, donkeys, yak and mithun are the pack animals for transport. The quality of work from the draught animals depends upon the power developed by them. The design of traditional implements is based on long experience and these have served the purpose of the farmers. However there is plenty of scope to improve the design based on animal-machine-environment interaction so as to have more output and increased efficiency without jeopardizing animal health.

    Agrobiodiversity and agroecosystem management have changed in central Himalaya due to increasing emphasis on market economy and the motive 'maximization of profit'. Such changes have benefited local people in economic terms, but at the same time increased their vulnerability to environmental and economic risks. The present study addressed the issue of how the ecological functions that are provided by agrobiodiversity translate into tangible benefits for the society. Important characteristics of agrodiversity management are the use of bullocks for draught power, human energy as labour, crop residues as animal feed and animal waste mixed with forest litter as organic input to restore soil fertility levels. The present analysis of resource input-output energy currency in traditional crop production indicated that inputs into different crop systems were significantly higher during kharif season compared to rabi season both under rainfed and irrigated conditions. The maximum input for crop during rabi season (second crop season) was about 31% of that of kharif season (first crop season after fallow) under rainfed conditions. Under irrigated conditions the rabi season input was about 63% of kharif season input. Under rainfed conditions, paddy sole cropping required maximum inputs (231.31 GJ/ha) as compared to mustard sole cropping (11.79 GJ/ha). The present investigation revealed that the total energy inputs and outputs are higher for irrigated agriculture as compared to rainfed system, the difference in inputs is about 5 fold and outputs is about 2 fold. The output-input ratio showed that irrigated systems have higher values as compared to rainfed systems. -- Highlights: → Agriculture continues to be biggest employment provider in the region. → Ecological functions that are provided by agrobiodiversity translate into tangible benefits for the society. → Analysis of resource input-output energy currency in traditional crop production. → Improvements in crop

    The ancient scientific Sanskrit texts of Ayurveda (science of longevity) deal with waters, plants, and animals in relation to human health. Based on the studies mentioned in Ayurveda and modern literature, biological responses of grazing animals in Mangampeta barite mining area in Kadapa District, Andhra Pradesh, were studied. A non-mineralized Tirupati area in Chittoor District, Andhra Pradesh, was selected for the purpose of comparison. In these areas, certain animal products of selected grazing animals were studied if they could be used as tools in mineral exploration. Samples of dung, urine, and milk from cow, bullock, she-buffalo, he-buffalo, sheep, and goat were collected from these two areas during winter and summer seasons. Goat dung was found to have lowest moisture content and highest organic matter while goat urine contained highest amounts of organic matter and ash content. All these animal products were analyzed for 11 trace elements. The concentration of trace elements released through dung, urine, and milk widely varied in different animal species with seasonal variations. The elemental concentration was higher in dung and lower in urine, when compared to that of milk. The concentration of all elements in dung, urine, and milk of all animals, in both the areas, was higher in winter than that in summer. Dung represents the metabolic process of the whole animal and reflects the dietary conditions whether fed on natural or inorganic supplement. It can be inferred that dung, urine, and milk of any animal can be used as tools in mineral exploration during winter, while during summer, only dung can be useful. The dung of goat when compared to that of the other cattle serves as a better tool in environmental studies as goat depends almost entirely on natural vegetation without human interference.

    The spherical Jeans equation is a widely used tool for dynamical study of gravitating systems in astronomy. Here, we test its efficacy in robustly weighing the mass of Milky Way analogues, given they need not be in equilibrium or even spherical. Utilizing Milky Way stellar haloes simulated in accordance with Λ cold dark matter (ΛCDM) cosmology by Bullock and Johnston and analysing them under the Jeans formalism, we recover the underlying mass distribution of the parent galaxy, within distance r/kpc ∈ [10, 100], with a bias of ˜ 12 per cent and a dispersion of ˜ 14 per cent. Additionally, the mass profiles of triaxial dark matter haloes taken from the SURFS simulation, within scaled radius 0.2 < r/rmax < 3, are measured with a bias of ˜ - 2.4 per cent and a dispersion of ˜ 10 per cent. The obtained dispersion is not because of Poisson noise due to small particle numbers as it is twice the later. We interpret the dispersion to be due to the inherent nature of the ΛCDM haloes, for example being aspherical and out-of-equilibrium. Hence, the dispersion obtained for stellar haloes sets a limit of about 12 per cent (after adjusting for random uncertainty) on the accuracy with which the mass profiles of the Milky Way-like galaxies can be reconstructed using the spherical Jeans equation. This limit is independent of the quantity and quality of the observational data. The reason for a non-zero bias is not clear, hence its interpretation is not obvious at this stage.

  2. Complex Engineered Systems: A New Paradigm

    Science.gov (United States)

    Mina, Ali A.; Braha, Dan; Bar-Yam, Yaneer

    Human history is often seen as an inexorable march towards greater complexity — in ideas, artifacts, social, political and economic systems, technology, and in the structure of life itself. While we do not have detailed knowledge of ancient times, it is reasonable to conclude that the average resident of New York City today faces a world of much greater complexity than the average denizen of Carthage or Tikal. A careful consideration of this change, however, suggests that most of it has occurred recently, and has been driven primarily by the emergence of technology as a force in human life. In the 4000 years separating the Indus Valley Civilization from 18th century Europe, human transportation evolved from the bullock cart to the hansom, and the methods of communication used by George Washington did not differ significantly from those used by Alexander or Rameses. The world has moved radically towards greater complexity in the last two centuries. We have moved from buggies and letter couriers to airplanes and the Internet — an increase in capacity, and through its diversity also in complexity, orders of magnitude greater than that accumulated through the rest of human history. In addition to creating iconic artifacts — the airplane, the car, the computer, the television, etc. — this change has had a profound effect on the scope of experience by creating massive, connected and multiultra- level systems — traffic networks, power grids, markets, multinational corporations — that defy analytical understanding and seem to have a life of their own. This is where complexity truly enters our lives.

    The monoecious, bird-pollinated epiphytic Tillandsia achyrostachys E. Morr. ex Baker var. achyrostachys is an endemic bromeliad of the tropical dry forests of Mexico with clonal growth. In the Sierra de Huautla Natural Reserve this species shows a host preference for Bursera copallifera (Sessé & Moc ex. DC) Bullock. As a result of deforestation in the study area, B. copallifera has become a rare tree species in the remaining forest patches. This human-induced disturbance has directly affected the population densities of T. achyrostachys. In this study the genetic consequences of habitat fragmentation were assessed by comparing the genetic diversity, gene flow and genetic differentiation in six populations of T. achyrostachys in the Sierra de Huautla Natural Reserve, Mexico. Allozyme electrophoresis of sixteen loci (eleven polymorphic and five monomorphic) were used. The data were analysed with standard statistical approximations for obtaining diversity, genetic structure and gene flow. Genetic diversity and allelic richness were: HE = 0.21 +/- 0.02, A = 1.86 +/- 0.08, respectively. F-statistics revealed a deficiency of heterozygous plants in all populations (Fit = 0.65 +/- 0.02 and Fis = 0.43 +/- 0.06). Significant genetic differentiation between populations was detected (Fst = 0.39 +/- 0.07). Average gene flow between pairs of populations was relatively low and had high variation (Nm = 0.46 +/- 0.21), which denotes a pattern of isolation by distance. The genetic structure of populations of T. achyrostachys suggests that habitat fragmentation has reduced allelic richness and genetic diversity, and increased significant genetic differentiation (by approx. 40 %) between populations. The F-statistic values (>0) and the level of gene flow found suggest that habitat fragmentation has broken up the former population structure. In this context, it is proposed that the host trees of T. achyrostachys should be considered as a conservation priority, since they represent the

    Sexually transmitted infections (STIs) are ongoing concerns. The best method for preventing the transmission of these infections is the correct and consistent use of condoms. Few studies have explored the use of games in interventions for increasing condom use by challenging the false sense of security associated with judging the presence of an STI based on attractiveness. The primary purpose of this study was to explore the potential use of computer simulation as a serious game for sex education. Specific aims were to (1) study the influence of a newly designed serious game on self-rated confidence for assessing STI risk and (2) examine whether this varied by gender, age, and scores on sexuality-related personality trait measures. This paper undertook a Web-based questionnaire study employing between and within subject analyses. A Web-based platform hosted in the United Kingdom was used to deliver male and female stimuli (facial photographs) and collect data. A convenience sample group of 66 participants (64%, 42/66) male, mean age 22.5 years) completed the Term on the Tides, a computer simulation developed for this study. Participants also completed questionnaires on demographics, sexual preferences, sexual risk evaluations, the Sexual Sensation Seeking Scale (SSS), and the Sexual Inhibition Subscale 2 (SIS2) of the Sexual Inhibition/Sexual Excitation Scales-Short Form (SIS/SES - SF). The overall confidence of participants to evaluate sexual risks reduced after playing the game (Psimulations as a serious game for sex education. Engaging in the Term on the Tides game had an impact on participants' confidence in evaluating sexual risks. ©Anastasia Eleftheriou, Seth Bullock, Cynthia A Graham, Roger Ingham.

    When Pioneer Venus arrived at Venus in 1978, it detected anomalously high concentrations of SO2 at the top of the troposphere, which subsequently declined over the next five years. This decline in SO2 was linked to some sort of dynamic process, possibly a volcanic eruption. Observations of SO2 variability have persisted since Pioneer Venus. More recently, scientists from the Venus Express mission announced that the SPICAV (Spectroscopy for Investigation of Characteristics of the Atmosphere of Venus) instrument had measured varying amounts of SO2 in the upper atmosphere; VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) measured no similar variations in the lower atmosphere (ESA, 4 April, 2008). In addition, Fegley and Prinn stated that venusian volcanoes must replenish SO2 to the atmosphere, or it would react with calcite and disappear within 1.9 my. Fegley and Tremain suggested an eruption rate on the order of approx 1 cubic km/year to maintain atmospheric SO2; Bullock and Grinspoon posit that volcanism must have occurred within the last 20-50 my to maintain the sulfuric acid/water clouds on Venus. The abundance of volcanic deposits on Venus and the likely thermal history of the planet suggest that it is still geologically active, although at rates lower than Earth. Current estimates of resurfacing rates range from approx 0.01 cubic km/yr to approx 2 cubic km/yr. Demonstrating definitively that Venus is still volcanically active, and at what rate, would help to constrain models of evolution of the surface and interior, and help to focus future exploration of Venus.

    Foram analisados 71 hemossoros de bovinos mestiços holandês-zebu, procedentes de cinco municípios da micro-região Mato-Grosso de Goiás. Os autores observaram que os valores obtidos para o gado mestiço holandês-zebu não diferem dos parâmetros fisiológicos estabelecidos pelos investigadores consultados, que trabalharam com gado de origem européia. As diferenças ocorridas poderão ser atribuídas a condições diversas, como por exemplo, as em que se desenvolveram o presente trabalho. Concluímos que, nas condições em que se realizou o presente trabalho, com animais em regime de campo, o gado mestiço holandês-zebu apresenta a importante característica de não aumentar a atividade de sua tireóide, em comparação com o gado de origem européia, apesar de habitar uma região onde as necessidades de dissipação do calor e de circulação sangüínea são mais intensas.

The Keck Array was first deployed in late 2010 and will observe through 2016 with five receivers at several frequencies (95, 150, and 220 GHz). bicep2 and the Keck Array share a common optical design and employ the field-proven bicep1 strategy of using small-aperture, cold, on-axis refractive optics, providing excellent control of systematics while maintaining a large field of view. This design allows for full characterization of far-field optical performance using microwave sources on the ground. Here we describe the optical design of both instruments and report a full characterization of the optical performance and beams of bicep2 and the Keck Array at 150 GHz.

    A study was conducted to determine the management practices followed by the farmers for draught cattle in Tamil Nadu state, India. Methods of procurement of animals, use of female animals, breeds preferred, housing, health, disposal of animals, feeding, shoeing, purchase of animal-drawn implements and their maintenance were all assessed with 210 farmers from seven districts across different agro-climatic zones in Tamil Nadu. The results revealed that 86 % of the respondents purchased the draught cattle from the livestock markets, most were bullocks but 20 small farmers and 5 medium farmers used female animals for ploughing. Among the indigenous breeds, Kangeyam (33 %) and Hallikar (30 %) breeds were the most popular for work. Most farmers (69 %) provided a mixed type of housing (provision of housing only during the night time and the rainy season) for their draught cattle. The major health problem reported by 63 % of respondents was pyrexia. Almost all farmers sold their animals at the age of 8-10 years. The feeding practices for draught cattle were poor especially with the small farmers. The cattle were fed with mainly paddy straw and rice bran. Oilcakes and cotton seeds were given to the animals which work throughout the year mainly for ploughing and carting. The draught cattle were first shod at around 2.5 years of age. The majority of the farmers (71 %) used the traditional animal-drawn implements made by local artisans, and the farmers were not aware of the new implements to reduce the drudgery of work cattle, designed by the Agricultural Machinery Research Centre and Agricultural Engineering Departments located in India.

    Youth, as future citizens, play an important role in obtaining and maintaining water resources. Water EducaTion for Alabama's Black Belt (WET Alabama) provides off-campus environmental and water-education activities designed to increase the appreciation, knowledge, conservation, and protection of water resources by middle-school teachers and children from predominantly African-American families in some of Alabama's poorest counties. The project is structured around a variety of indoor and outdoor activities held at two field sites, Auburn University's E. V. Smith Center in Macon County and the Robert G. Wehle Nature Center in Bullock County located in Alabama's "Black Belt" region, a region in which the prosperity of local communities is low. The educational activities provide an engaging laboratory and field experience for children from rural schools that lack scientific facilities and equipment. Both hosting centers have easy access to surface water (ponds, wetlands, streams) and offer facilities for basic hydrologic experiments (e.g., aquifer models, permeameter, water quality). The E.V. Smith site has access to groundwater through pairs of nested wells. Educational activities are designed to help students and teachers visualize groundwater flow and its interaction with surface water in an aquifer tank model; compare the hydrologic properties (porosity and permeability) of different aquifer materials (sands, gravels, and clays); learn about groundwater purging and sampling; and assess water quality and flow direction in the field. Simple exercises demonstrate (1) the balance of recharge and discharge, (2) the effects of flooding, drought and pumping, and (3) movement of contaminants through aquifers. A set of ready-to-teach laboratory exercises and tutorials address goals specified by the State of Alabama science curriculum for grades 6 to 8. The ultimate goal of Project WET Alabama is to help students and teachers from resource-poor schools become knowledgeable

    Farm power and equipment role was established in agriculture beyond doubt for sustainable development but hill farming is still facing shortage of farm power and matching equipment for timely and precisely operations. A study was carried out on performance evaluation of different light weight power tillers/weeders designated as P1, P2, P3 and P4 under dry and wet land conditions to meet out the demand of farm power for mechanizing hill agriculture, particularly under small and irregular shaped terraces having high vertical intervals where it is difficult to operate commercially available power tillers. Four power tillers in the horse power range of 3.0-7.0 hp manufactured and marketed by Indian firms were tested in silty-clay-loam soil at the HPKV farm, Palampur, India. The results showed that the depth of operation was less than 80 mm with P1, P2 as well as P3 power tiller after two passes of rotary at soil moisture content of 16.4% whereas, it was 102 mm with P4. The average effective field capacity was 0.055, 0.051, 0.042 and 0.060 ha/h under dry land conditions with P1, P2, P3 and P4, respectively whereas in wetland condition the capacity was 0.042, 0.038 and 0.05 with P1, P2, and P4, respectively. P3 power tiller could not be possible to test under wet land conditions due to less ground clearance of the engine. The cost of repair and maintenance was observed to be very high in case of P1, P2 and P3 power tillers due to the occurrence of frequent breakdowns. It was construed from the study that the power tillers up to 5 hp are not suitable for seed-bed preparation but it could be used as weeder for interculture operations in wide row spaced crops. However, P4 power tiller performed better than other models under different conditions. There was saving of 50-66% in time and 66-75% cost of operation observed with different makes of power tillers as compared to bullock ploughing.

    A growing number of online communities have been established to support those who self-harm. However, little is known about the therapeutic affordances arising from engagement with these communities and resulting outcomes. The aim of this study was to explore the presence of therapeutic affordances as reported by members of self-harm online support communities. In total, 94 respondents (aged 13-63 years, mean=23.5 years; 94% female) completed an online survey exploring their experiences of engaging with a self-harm online support community. Respondents varied in terms of how long they had been accessing an online community, with 22% (21/94) accessing less than 1 year, 39% (37/94) 1 to 2 years, 14% (13/94) 2 to 3 years, and 24.5% (23/94) more than 3 years. Responses were analyzed using deductive thematic analysis. The results of our analysis describe each of the five therapeutic affordances that were present in the data, namely (1) connection, the ability to make contact with others who self-harm for the purposes of mutual support and in so doing reduce feelings of loneliness and isolation; (2) adaptation, that is, how use of online support varies in relation to the personal circumstances of the individual user; (3) exploration, that is, the ability to learn about self-harm and learn about strategies to reduce or stop self-harming behavior; (4) narration, that is, the ability to share experiences, as well as read about the experiences of others; and (5) self-presentation, that is, how and what users present about themselves to others in the online community. Our findings suggest that engagement with self-harm online support communities may confer a range of therapeutic benefits for some users, which may serve to minimize the psychosocial burden of self-harm and promote positive coping strategies. In addition, the online nature of the support available may be helpful to those who are unable to access face-to-face support. ©Neil S Coulson, Emma Bullock, Karen Rodham

    with 606 and 228 articles respectively. According to inclusion and exclusion criteria, 18 articles were selected for study. For any knee injury risk factors are a previous injury, fatigue and muscle strength imbalance between hamstrings and the quadriceps muscle (McCall y col., 2014. In the case of ACL injury studies focus on causes like the Q angle, the valgus knee, the genu recurvatum, the pronator foot and the external tibial torsion among others. In addition, the ACL of women is smaller in length and has smaller cross section than the ACL of men (Sutton y Bullock, 2013. Prevention programs included training the core, propioception, flexibility, motor control, learn technique and eccentric work (McCall y col., 2014; Myer y col., 2012; Stevenson y col., 2014; Sugimoto y col., 2014. In conclusion, the specific risk factors for this injury in women are presented with the effectiveness shown in the different preventive programs analyzed. The prevention programs analyzed include improvements for neuromuscular strength, stretching, plyometry, balance, core and correction of the technique of jump landing and changes of direction.

    definition of scaled radius, or concentration; and gamma approx 1.2-1.3 deduced from more recent high-resolution simulations (Diemand et al. 2004, Reed et al. 2005). No evident correlation is found between SDH dynamical state (relaxed or merging) and asymptotic inner slope of the fitting logarithmic density profile or (for SDH comparable virial masses) scaled radius. Mean values and standard deviations of some parameters are calculated, and in particular the decimal logarithm of the scaled radius, xivir, reads =0.74 and sigma_s log xivir=0.15-0.17, consistent with previous results related to NFW density profiles. It provides additional support to the idea, that NFW density profiles may be considered as a convenient way to parametrize SDH density profiles, without implying that it necessarily produces the best possible fit (Bullock et al. 2001). A certain degree of degeneracy is found in fitting GPL to SDH density profiles. If it is intrinsic to the RFSM5 method or it could be reduced by the next generation of high-resolution simulations, still remains an open question.

    The National Beef Quality Audit-2000 was conducted to assess the current status ofthe quality and consistency of U.S. fed steers and heifers. Between May and November 2000, survey teams assessed hide condition (n = 43,415 cattle for color, brands, mud/manure), bruises (n = 43,595 carcasses), offal and carcass condemnation (n = 8,588 cattle), and carcass quality and yield information (n = 9,396 carcasses) in 30 U.S. beef packing plants. Hide colors were black (45.1%), red (31.0%), yellow (8.0%), Holstein (5.7%), gray (4.0%), white (3.2%), brown (1.7%), and brindle (1.3%). Brand frequencies were no (49.3%), one (46.2%), and two or more (4.4%), and brands were located on the butt (36.3%), side (13.7%), and shoulder (3.6%). Most cattle had no (18.0%) or a small amount (55.8%) of mud/manure on their hides, and they had no (77.3%) horns. Most carcasses (53.3%) were not bruised, 30.9% had one bruise, and 15.8% had multiple bruises. Bruise location and incidence were round (14.9%), loin (25.9%), rib (19.4%), chuck (28.2%), and brisket, flank, and plate (11.6%). Condemnation item and incidence were liver (30.3%), lungs (13.8%), tripe (11.6%), heads (6.2%), tongues (7.0%), and carcasses (0.1%). Carcass evaluation revealed these traits and frequencies: steer (67.9%), heifer (31.8%), and bullock (0.3%) sex-classes; dark-cutters (2.3%); A (96.6%), B (2.5%), and C or older (0.9%) overall maturities; and native (90.1%), dairy-type (6.9%), and Bos indicus (3.0%) breed-types. Mean USDA yield grade traits were USDA yield grade (3.0), carcass weight (356.9 kg), adjusted fat thickness (1.2 cm), longissimus muscle area (84.5 cm2), and kidney, pelvic, and heart fat (2.4%). USDA yield grades were Yield Grade 1 (12.2%), Yield Grade 2 (37.4%), Yield Grade 3 (38.6%), Yield Grade 4 (10.4%), and Yield Grade 5 (1.3%). Mean USDA quality grade traits were USDA quality grade (Select85), marbling score (Small23), overall maturity (A66), lean maturity (A65), and skeletal maturity (A67). Marbling

    signal variation, or to see at which scales signals are most correlated. This can give us an insight into the dominant processes An alternative to both of the above methods has been described recently. Relative entropy and increments in relative entropy has been applied in soil images (Bird et al., 2006) and in soil transect data (Tarquis et al., 2008) to study scale effects localized in scale and provide the information that is complementary to the information about scale dependencies found across a range of scales. We will use them in this work to describe the spatial scaling properties of a set of field water content data measured in an extension of a corn field, in a plot of 500 m2 and an spatial resolution of 25 cm. These measurements are based on an optics cable (BruggSteal) buried on a ziz-zag deployment at 30cm depth. References Bird, N., M.C. Díaz, A. Saa, and A.M. Tarquis. 2006.

    Livestock are vital to sustainable agriculture in most developing countries. In Asia, in general, the integration of livestock, fish and crops has proved to be a sustainable system through centuries of experience. Traditional use of dung for manuring the fields and bullocks for ploughing is the 'biodynamic farming', which has special significance in dry land agriculture comprising about 65 percent of India's cropped area. Gene-based technologies will be useful for developing special draught breeds of cattle so that their valuable source of energy remains available especially to the small and marginal farmers. Further, the livestock in the developing countries form an essential part of an integrated agricultural system and, therefore, development strategies for gene-based applications should consider the total production system (i.e., breeding fodder and forage crops, animal and crop disease and pest management etc). The gene-technologies of relevance to the developing countries are (i) rumen molecular techniques for reducing methane production and for increasing protein and energy supply; ruminant food stuffs currently used in India and a few other developing countries are fibrous, low in nitrogen, and contain anti-nutritive factors, (ii) improving animal productivity in developing countries by manipulation of nutrition in utero to alter gene expression of key metabolic hormones and enzymes for a long period after birth in cattle, (iii) genetic resistance to Helminthes in sheep, and (iv) molecular methods of diagnosis, molecular epidemiology and treatment of swine fever. Although not gene-based, artificial insemination (AI) for genetic improvement of dairy cattle and buffalo, and embryo-transfer (ET) for rapid multiplication of elite cattle are also relevant. Cloning (of the 'Dolly' - the sheep kind) will be useful to revive the rare and endangered animal species such as one-horned rhinoceros, swamp deer, wild buffalo and dugongs in India, for restoring

    en él se pueden celebrar competiciones deportivas y gimnásticas, espectáculos musicales, cinematográficos y circenses e incluso exposiciones, reuniones y congresos. La entrada, desde la plaza, se realiza a través de una galería acristalada que rodea al edificio y que comunica con el corredor interior que circunda la pista. Tiene capacidad para más de 11.000 plazas, si bien hay unas plataformas telescópicas que se despliegan en el nivel de la pista, y sillas portátiles que la aumentan hasta un total de 16.500 plazas. El edificio está cubierto por una armadura de acero, limitada exteriormente con un amplio voladizo metálico. Todo el sistema va apoyado sobre 32 grandes pilares de hormigón, en forma de U, que quedan manifestados en el exterior de la fachada. El Coliseo cuenta con instalaciones de iluminación y sonido del tipo teatral, con lo que se consigue adecuarlo a cada una de las distintas manifestaciones. Bajo la plaza adyacente se ha dispuesto una gran sala de exposiciones subterránea, que complementa al Coliseo. Tiene una superficie de más de 5.700 m2, que se puede subdividir en espacios más pequeños, de acuerdo con las necesidades, por medio de paneles plegables. Centro comercial de Bullock´s en Norhtridge. La principal característica de este gran almacén es su total tratamiento a modo de escenario para las diversas mercancías que en él se exponen. Por otra parte, su diseño ha roto con el molde tradicional en forma de caja, típico de estos edificios, sustituyéndolo por un volumen poliédrico de efecto más dinámico. En él se ha dado tanta importancia a los espacios arquitectónicos como al sistema de iluminación y a la decoración. Así, mediante los distintos efectos luminosos, se consigue resaltar o quitar importancia a las diversas zonas, mientras que los adornos y las formas arquitectónicas limitan, diferenciando, las distintas áreas de exposición de artículos. Un sistema ornamental y de particiones móviles dotan al conjunto

  1. EDITORIAL: Environmental justice: a critical issue for all environmental scientists everywhere

    when an issue of water contamination becomes an issue of environmental injustice? How do we measure the impacts of environmental harm today on future generations? How do we measure the distribution of multiple or cumulative impacts on poorer groups? How do we quantify the responsibility of richer citizens in the world for the environmental harms distributed unequally to the poorer citizens? The papers in this focus issue do not answer all these questions, but we hope that this theme will recur in Environmental Research Letters and that more environmental scientists will begin to frame their analyses around the critical issues of distributions of environmental harms and benefits.

    stimulate further research on this critical subject. The study of climate involves much more than understanding atmospheric processes. This subtlety is particularly appreciated for Earth, where chemical cycles, geology, ocean influences, and biology are considered in most climate models. In Part IV, Surface and Interior, we look at the role that geochemical cycles, volcanism, and interior mantle processes play in the stability and evolution of terrestrial planetary climates. There is one vital commonality between the climates of all the planets of the solar system: Regardless of the different processes that dominate each of the climates of Earth, Mars, Venus, and Titan, they are all ultimately forced by radiation from the same star, albeit at variable distances. In Part V, Solar Influences, we discuss how the Sun's early evolution affected the climates of the terrestrial planets, and how it continues to control the temperatures and compositions of planetary atmospheres. This will be of particular interest as models of exoplanets, and the influences of much different stellar types and distances, are advanced by further observations. Comparisons of atmospheric and climate processes between the planets in our solar system has been a focus of numerous conferences over the past decade, including the Exoclimes conference series. In particular, this book project was closely tied to a conference on Comparative Climatology of Terrestrial Planets that was held in Boulder, Colorado, on June 25-28, 2012. This book benefited from the opportunity for the author teams to interact and obtain feedback from the broader community, but the chapters do not in general tie directly to presentations at the conference. The conference, which was organized by a diverse group of atmospheric and climate scientists led by Mark Bullock and Lori Glaze, sought to build connections between the various communities, focusing on synergies and complementary capabilities.
