  9. Comparative economics of bullock and tractor use in Rajasthan

    Energy Technology Data Exchange (ETDEWEB)

    Goyal, D.; Joshi, B.R.; Taimni, V.


    Bullocks have traditionally been an important source of traction power in the agricultural sector of arid areas of western Rajasthan. The advent of the green revolution and massive allocation of planned resources for rapid agricultural development have generated sizable element of competition in the pattern of power use in farm sectors. This study has revealed a positive case for limited substitution of bullocks by tractors in the arid region and has further indicated that under the constrained availability of tractors, complete substitution of bullocks would result in wastage of the available power resource of the arid region. It has been inferred that a limited substitution of power use should be allowed in arid farms where the time of completing farm chores is the overriding consideration. Even this limited substitution will need a vigorous infra-structural development for meeting the input-demands created by the increased quantum of mechanical energy use.

  10. Lean color characteristics of bullock and steer beef. (United States)

    Shackelford, S D; Purser, D E; Smith, G C; Griffin, C L; Stiffler, D M; Savell, J W


    Twelve young bulls and 12 steers were slaughtered and the carcasses were fabricated at 48 h postmortem. Top rounds, bottom rounds, and rib eyes were vacuum-packaged and stored at 0 degrees C until 21 d postmortem. After subprimal storage, steaks were removed from each cut and displayed under simulated retail conditions for 3 d. Consumer panelists (n = 110) showed little difference in buying preference for top round, bottom round, and rib eye steaks from steers vs bullocks. Also, consumer panelists could not detect color differences between steaks from steers and bullocks. Experienced panelists (n = 6) detected brighter (P less than .05) muscle color for top round and rib eye steaks from steers but detected no difference in muscle color of bottom round steaks from bullocks and steers. Generally, overall desirability scores favored steaks from steer carcasses. This was particularly true of rib eye steaks. Sex-class of carcass did not affect aerobic plate counts of top round, bottom round, or rib eye steaks either before or after 3 d of retail display. Muscle pH was lower for top round and rib eye steaks from steer carcasses; however, the magnitude of this difference was not large enough to affect retail display stability. Muscle pH of bottom round steaks was not affected by sex-class. Although experienced panelists could detect differences in visual appearance of beef retail cuts from steers and bullocks, consumer panelists did not show a clear purchase preference for steer vs bullock beef. These data suggest that beef retail cuts from bullocks are acceptable in visual appearance.

  11. Energetics on bullock- and tractor-powered farms in India

    Energy Technology Data Exchange (ETDEWEB)

    Gupta, R.S.R.; Malik, R.K.; Gupta, R.R.; Rao, A.R.


    Data collected for 20 tubewell-irrigated farms of the Karnal district in North India have been analyzed for the energy inputs through animate and inanimate resources into farm equipment and machinery. All the inputs into equipment from mining to fabrication and maintenance, or as fodders to raise and maintain bullocks, have been taken into account with due weight given for scrap. Energy inputs due to agricultural equipment for a hectare of wheat crop are estimated at 38.7 GJ on bullock-powered farms, and 14.6 GJ on tractor-operated farms. 10 references, 6 tables.

  19. Theodore H. Bullock: pioneer of integrative and comparative neurobiology. (United States)

    Zupanc, G K H; Zupanc, M M


    Theodore H. Bullock (1905-2005) was a pioneer of integrative and comparative neurobiology and one of the founders of neuroethology. His work--distinguished by the tremendous number of different research themes and animal taxa studied--provided the basis for a comprehensive analysis of brain evolution. Among his major achievements are: one of the first physiological analyses of rhythmic central pattern generators; the first simultaneous recording from both the presynaptic and postsynaptic region of a chemical synapse; the demonstration of intercellular communication through graded potentials; and the discovery of two novel sensory organs formed by infrared receptors in pit vipers and electroreceptors in electric fish. He was also one of the first who applied computational tools to the analysis of complex neural signals and to perform a comparative analysis of cognitive events. His two-volume treatise "Structure and function in the nervous system of invertebrates" (with G. Adrian Horridge) remains the most comprehensive, authoritative review of this topic ever written. In addition to his research merits, his legacy is particularly based on his cosmopolitan way of thinking and acting, his large, worldwide school of students, and his committed advocacy for comparative and systems-oriented neurobiology.

  20. Lectin binding patterns in hyperplastic and metaplastic bullock prostate tissues after diethylstilbestrol administration. (United States)

    Fernández, P E; Barbeito, C G; Portiansky, E L; Gimeno, E J


    Hyperplasia and squamous metaplasia of the prostatic epithelium are conditions induced by oestrogens. Diethylstilbestrol (DES) has been banned from cattle used for beef production because of the health risks. The potential use of molecular markers for the detection of illegal oestrogen administration was evaluated by taking samples of prostatic tissue from control bullocks, bullocks which had been treated with oestrogens, and bullocks sacrificed 21 and 90 days after a single dose of DES. The expression of the glycoconjugates was examined by lectinhistochemistry and the lectin binding pattern was characterised in epithelium and connective tissue. In the animals sacrificed after 21 days there was an increase in the binding of one lectin (JAC) and there was an increase in the binding of one of the other lectins (DBA) in the animals sacrificed after 90 days. An increase in SWGA lectin staining was observed in the bullocks that had probably been treated with oestrogen and in the animals sacrificed 90 days after the inoculation with DES. There were also differences between the binding of SWGA in the control bullocks and the other groups.

  2. Effects of prostaglandins and thromboxane analogues on bullock and dog iris sphincter preparations. (United States)

    Dong, Y J; Jones, R L


    1 The bullock iris sphincter was contracted by low concentrations of prostaglandin E2 (PGE2), 16, 16-dimethyl PGE2 and 17,18,19,20-tetranor-16-p-chlorophenoxy PGE2. Other compounds with thromboxane-like actions, for example 11,9-epoxymethano PGH2, were also potent spasmogens, ZK 36374, a stable carbacyclin, was a partial agonist on the PGE-sensitive system of this tissue. 2 The thromboxane antagonist, EP 045, had little effect on the action of PGE2 and 16,16-dimethyl PGE2 on the bullock iris. 3 The dog iris sphincter was sensitive to PGF2 alpha but not to PGE2 and 11,9-epoxymethano PGH2. 4 16,16-dimethyl PGE2 had very low activity on the dog iris in contrast to its high activity on the bullock iris. The reverse was found with the 17,18,19,20-tetranor-16-m-trifluoromethylphenoxy analogue of PGF2 alpha (ICI 81008). This indicates a considerable selectivity of action of the two analogues. 5 The results are discussed in relation to the existing knowledge of prostanoid receptors.

  6. Anti-herpes simplex virus activities of Eugenia caryophyllus (Spreng.) Bullock & S. G. Harrison and essential oil, eugenol. (United States)

    Tragoolpua, Y; Jatisatienr, A


    In this study, an extract from the flower buds of Eugenia caryophyllus (Spreng.) Bullock & S. G. Harrison and the essential oil, eugenol, were evaluated for their anti-herpes simplex virus properties on standard HSV-1(F), standard HSV-2(G) and ten HSV isolates. The plaque reduction assay showed that HSV-1(F), HSV-2(G), two HSV-1 isolates (2, 30) and four HSV-2 isolates (1, 2, 3, 21) were inhibited by E. caryophyllus. Only HSV-1 isolates 1 and 30 were inhibited by eugenol. Thus, strains or isolates of viruses may affect the range of inhibition. Moreover, particles of HSV standard strains were directly inactivated by E. caryophyllus and eugenol. The total virus yield of HSV standard strains and isolates at 30 h also declined after treatment with E. caryophyllus and eugenol. The E. caryophyllus extract exerted higher antiviral replication on HSV-2(G) than on HSV-1(F). The inhibition of the viral yield of HSV-1 isolates was higher than standard HSV-1(F) and standard HSV-2(G) was also inhibited more than most of the HSV-2 isolates. The anti-HSV activity of eugenol against HSV-1(F) and HSV isolates was stronger than with the E. caryophyllus crude extract. However, the percentage inhibition was more pronounced on HSV-1(F) than on HSV-2(G). Moreover, HSV-1(1) and HSV-2(1, 32) could not replicate when eugenol was included in the assay.

  7. Similar reproductive status and body size of horse flies (Diptera: Tabanidae) attracted to carbon dioxide-baited canopy traps and a Jersey bullock. (United States)

  20. Present status and future demand for energy for bullock-operated paddy-farms in Assam (India)

    Energy Technology Data Exchange (ETDEWEB)

    Baruah, D.C.; Das, P.K.; Dutta, P.K. [Assam Agricultural Univ., Jorhat (India). Dept. of Agricultural Engineering


    The existing energy-use pattern, based on the prevailing cultivation practices and the optimal energy-demand based on the optimal mechanization strategy for animal operated paddy farms of Assam (India) were assessed. Two categories of paddy farms, i.e. with and without the use of chemical fertilizers were identified. Lower yield (1976 kg/ha) associated with a lower energy-input (5681 MJ/ha) was the characteristic feature of farms not using fertilizer in contrast to the higher yield (3165 kg/ha) and energy input (9290 MJ/ha) of fertilizer-user farms. Human and animal (as also chemical fertilizer for fertilizer-user farms) were the major energy sources under the existing practices contributing to more than 70% of the total energy-input. The optimal demand of energy to achieve a potential paddy yield of 6000 kg/ha was estimated as 11,168 MJ/ha comprising human, animal, diesel, and fertilizers as the major energy sources. Though the overall energy demand increased, the introduction of improved tillage implements could reduce the future optimal demand of animal energy for animal-operated paddy farms in Assam. (author)

  1. Why Pr. Bullock Is Not Entirely Right and Pr. Tullock Is Completely Wrong: The Case for Road Privatization

    Directory of Open Access Journals (Sweden)

    Laurent A.H. Carnis


    Full Text Available The private provision of road services and road privatisation has been extensively studied and has generated numerous debates among scholars. Block and Tullock exchanged on the possibility of having a completely privatised road system. Tullock defends the idea such a system is not viable, whereas Block shows a free market for road provision can be easily conceived.This article proposes a re-examination of this debate and defends a pragmatic and realist approach. Although it shares Block’s conclusions on the possibility of having a free market for road services, it justifies them on a different ground. In fact, the ‘physical obstacle’ argument is less important that it could be previously imagined but it reflects more a socialist tendency to pose the problem.

  12. Pharmacological investigation on nigrescigenin-a cardenolide from Parquetina nigrescens (Afzel.) Bullock: comparative studies on cardiotonic effects of Parquetina nigrescens, g-strophanthin and noradrenaline in guinea-pig isolated atria. (United States)

    Datté, J Y; Ziegler, A


    The cardiotonic and catecholamine-like effects of Parquetina nigrescens extract-induced contractile force of guinea-pig left and right atria were investigated in-vitro. Isometric contractions were recorded. P. nigrescens extract, 5-150 microg mL(-1), increased the force of contraction dose dependently in electrically driven left atria. The concentration of P. nigrescens extract producing 50% of the maximal effect (EC50 value) was 7.5 microg mL(-1). The positive inotropic response differed from that of g-strophanthin by its high rate of onset and its complete reversibility upon removal of the extract from the incubation medium. In spontaneously beating right atrial muscle, P. nigrescens extract increased the rate of contractions. Its positive chronotropic and inotropic effects were partly antagonized by propranolol and atenolol indicating the presence of an adrenergic acting principle in P. nigrescens extract. In contrast, the inotropic response to P. nigrescens extract could not be completely suppressed by beta-blocking agents, suggesting that the force of contraction is not only increased by a sympathomimetic ingredient of P. nigrescens extract but also by the cardenolides known to be present in P. nigrescens.

  1. A further note on the scientific name of Bullocks’ Oriole (United States)

    Chesser, R. Terry


    Chesser (2013) intended to introduce a justified emendation to Icterus bullockii under Article 32.5.1 of the Code (ICZN 1999), because the name honors both William Bullock, Sr., and William Bullock, Jr. However, the correction bullockorum is "incorrect" and therefore is an unjustified emendation (Article 33.2.3). Under the assumption that the name Bullock was latinized (cf. Article 31.1.1) to Bullockius (bullocki– + the nominative case ending –us) and therefore that the name bullockii comprises the stem bullocki– + the genitive case ending –i, the justified correction bullockiorum is required.

  13. On the correct name of Icterus bullockii (Passeriformes: Icteridae) (United States)

    Chesser, R. Terry


    William Bullock was an Englishman who owned the Egyptian Hall (also known as the London Museum or Bullock’s Museum) at Piccadilly in London, a museum opened in 1812 to display his collection of antiquities, artifacts, and natural history specimens. Following the sale of Bullock’s collection in 1819, the Egyptian Hall served as an exhibition space. Bullock and his son, William Bullock, Jr., both enthusiastic naturalists, travelled in Mexico in 1822–1823, spending some six months together collecting natural history specimens and other artifacts for exhibition and investigating mining and other business opportunities (Costeloe 2006). The elder Bullock returned to London with the collections in 1823, but his son, while ostensibly managing the silver mine his father had purchased in Temascaltepec, outside of Mexico City, continued to travel in Mexico and collect specimens, often in the company of German naturalist Ferdinand Deppe (Costeloe 2006). William Bullock, Sr., meanwhile prepared the Mexican collection for exhibition at the Egyptian Hall. Twin exhibitions on ancient and modern Mexico opened, with much fanfare, in April 1824, and were a great success, remaining open until September 1825 (Costeloe 2006). Afterwards, the contents of the exhibitions were dispersed via auction, but not before Bullock had made the bird specimens available to English naturalist William Swainson for “recording this portion of his discoveries” (Swainson 1827: 365).

  18. The sustainability of changes in agricultural technology: The carbon, economic and labour implications of mechanisation and synthetic fertiliser use. (United States)

    Gathorne-Hardy, Alfred


    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.

  1. The management and welfare of working animals: identifying problems, seeking solutions and anticipating the future. (United States)

    Abul Rahman, S; Reed, K


    Working animals, mainly equids, camelids and bovids, are draught animals that perform transport and traction activities. In developed countries technological development has resulted in animal power being minimised, however, in developing countries most agricultural operations are still being conducted by animals, and animal welfare is a major concern. Inadequate knowledge and inappropriate attitudes and practices regarding the management and welfare of working animals are the main contributory factors to welfare problems. The paper highlights the situation of working animals in developing countries, especially those of equids in Africa and Asia and bullocks in India, which are examined as examples. There is much room for improvement in the welfare of working animals, via the provision of basic veterinary care, technical advice on health and husbandry, including foot care, improved design and maintenance of harnesses and other equipment, and the development of appropriate policies and legislation. The paper discusses the role of the World Organisation for Animal Health in addressing these issues.

  2. Probing Milky Way's hot gas halo density distribution using the dispersion measure of pulsars

    CERN Document Server

    Nugaev, Emin Ya; Zhezher, Yana V


    A number of recent studies indicates a significant amount of ionized gas in a form of the hot gas halo around the Milky Way. The halo extends over the region of 100 kpc and may be acountable for the missing baryon mass. In this paper we calculate the contribution of the proposed halo to the dispersion measure (DM) of the pulsars. The Navarro, Frenk & White (NFW), Maller & Bullock (MB) and Feldmann, Hooper & Gnedin (FHG) density distibutions are considered for the gas halo. The data set includes pulsars with the distance known independently from the DM, e.g. pulsars in globular clusters, LMC, SMC and pulsars with known parallax. The results exclude the NFW distribution for the hot gas, while the more realistic MB and FHG models are compatible with the observed dispersion measure.

  3. Recognizing Small-Circuit Structure in Two-Qubit Operators

    Shende, V V; Markov, I L; Shende, Vivek V.; Bullock, Stephen S.; Markov, Igor L.


    This work describes numerical tests which determine whether a two-qubit quantum computation has an atypically simple quantum circuit. Specifically, we describe forumulae, written in terms of matrix coefficients, characterizing operators implementable with exactly zero, one, or two controlled-not gates with all other gates being local unitary. Circuit diagrams are provided in each case. We expect significant impact in physical implementations where controlled-not's are more difficult than one-qubit computations. Our results can be contrasted with those by Zhang et al., Bullock and Markov, Vidal and Dawson, and Shende et al. In these works, small quantum circuits are achieved for arbitrary two-qubit operators, and the latter two prove three controlled-not's suffice. However, unitary operators with the sort of structure described above may not be detected. Our work provides results similar to those by Song and Klappenecker but for a wider range of operators.

    Full Text Available The objective of this study was to evaluate the effects of feeding cattle with isoprotein and isoenergetic diets, with and without the addition of polyclonal antibody preparation (PAP, yeasts (YST or monensin sodium (MON on performance, carcass characteristics and gain cost in feedlot. Ninety-five 20-month old bullocks (323.3±21.8 kg were distributed in 25 pens. The completely randomized experimental design had a 2 × 2 + 1 factorial arrangement and the treatments were replicated 5 times. There was no effect of MON for DMI throughout the feedlot period; however, MON reduced the dry matter intake (DMI in g/kg of BW in the first 28 days when compared with the other treatments. The gain cost decreased with MON addition in relation to the other treatments. Inclusion of YST decreased average daily gain (ADG, final body weight, hot carcass weight, carcass weight, gain to feed ratio and DMI in g/kg body weight, worsening feed conversion and increasing the gain cost in the feeding periods. Inclusion of PAP increased ADG and decreased the gain cost, besides improving feed conversion. For MON and PAP, a difference was found for kidney-pelvic fat and kidney-pelvic fat per 100 kg of hot carcass weight. For MON and YST, there was a difference in ADG, feed conversion, gain cost and carcass yield and kidney-pelvic fat per 100 kg of hot carcass. Treatment YST worsened performance in relation to the non-supplemented treatments. Feeding PAP to animals did not influence performance and carcass characteristics of bullocks in feedlot negatively. Thus, PAP shows potential to substitute MON in cattle feeding using isoprotein and isoenergetic diets.

    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.

  8. Architecture of the Andromeda galaxy: a quantitative analysis of clustering in the inner stellar halo (United States)

    Kafle, P. R.; Sharma, S.; Robotham, A. S. G.; Lewis, G. F.; Driver, S. P.


    We present a quantitative measurement of the amount of clustering present in the inner ˜30 kpc of the stellar halo of the Andromeda galaxy (M31). For this we analyse the angular positions and radial velocities of the carefully selected planetary nebulae in the M31 stellar halo. We study the cumulative distribution of pairwise distances in angular position and line-of-sight velocity space, and find that the M31 stellar halo contains substantially more stars in the form of close pairs as compared to that of a featureless smooth halo. In comparison to a smoothed/scrambled distribution, we estimate that the clustering excess in the M31 inner halo is roughly 40 per cent at maximum and on average ˜20 per cent. Importantly, comparing against the 11 stellar halo models of Bullock & Johnston, which were simulated within the context of the ΛCDM (Λ cold dark matter) cosmological paradigm, we find that the amount of substructures in the M31 stellar halo closely resembles that of a typical ΛCDM halo.

  10. Bioinspired Design and Computational Prediction of Iron Complexes with Pendant Amines for the Production of Methanol from CO2 and H2. (United States)

    Chen, Xiangyang; Yang, Xinzheng


    Inspired by the active site structure of [FeFe]-hydrogenase, we built a series of iron dicarbonyl diphosphine complexes with pendant amines and predicted their potentials to catalyze the hydrogenation of CO2 to methanol using density functional theory. Among the proposed iron complexes, [(P(tBu)2N(tBu)2H)FeH(CO)2(COOH)](+) (5COOH) is the most active one with a total free energy barrier of 23.7 kcal/mol. Such a low barrier indicates that 5COOH is a very promising low-cost catalyst for high-efficiency conversion of CO2 and H2 to methanol under mild conditions. For comparison, we also examined Bullock's Cp iron diphosphine complex with pendant amines, [(P(tBu)2N(tBu)2H)FeHCp(C5F4N)](+) (5Cp-C5F4N), as a catalyst for hydrogenation of CO2 to methanol and obtained a total free energy barrier of 27.6 kcal/mol, which indicates that 5Cp-C5F4N could also catalyze the conversion of CO2 and H2 to methanol but has a much lower efficiency than our newly designed iron complexes.

  11. Asymptotically Optimal Quantum Circuits for d-level Systems

    CERN Document Server

    Bullock, S S; O'Leary, D P; Brennen, Gavin K.; Bullock, Stephen S.; Leary, Dianne P. O'


    As a qubit is a two-level quantum system whose state space is spanned by |0>, |1>, so a qudit is a d-level quantum system whose state space is spanned by |0>,...,|d-1>. Quantum computation has stimulated much recent interest in algorithms factoring unitary evolutions of an n-qubit state space into component two-particle unitary evolutions. In the absence of symmetry, Shende, Markov and Bullock use Sard's theorem to prove that at least C 4^n two-qubit unitary evolutions are required, while Vartiainen, Moettoenen, and Salomaa (VMS) use the QR matrix factorization and Gray codes in an optimal order construction involving two-particle evolutions. In this work, we note that Sard's theorem demands C d^{2n} two-qudit unitary evolutions to construct a generic (symmetry-less) n-qudit evolution. However, the VMS result applied to virtual-qubits only recovers optimal order in the case that d is a power of two. We further construct a QR decomposition for d-multi-level quantum logics, proving a sharp asymptotic of Theta(d...

  12. Angular Momentum in the Formation of Disk Galaxies

    Institute of Scientific and Technical Information of China (English)

    LUO Zhi-Jian; SHU Cheng-Gang


    @@ Within the current framework of disk galaxy formation, we discuss the resulted surface-density profiles according to the theoretical angular momentum distributions (AMDs) presented by Bullock et al. [Astrophys. J.555 (2001) 240(B01)] for the ACDM cosmology in both spherical and cylindric coordinates. It is found that the derived surface density distribution of a disk in the outer region is in general similar to an exponential disk for both the theoretical AMDs. In the central region, the results from both the theoretical AMDs are inconsistent with observations whatever the disk bar-instability is taken into account or not. The cylindric form of the theoretical AMD leads to the bar-instability more easily for a give galaxy than that for spherical AMD, which could result in a more massive bulge. After comparing the model predictions with our Milky Way galaxy, we find that the theoretical AMDs predict larger mass fractions of baryons with low angular momentum than the observed ones, which would lead to the disk sizes to be smaller. Two possible processes which could solve the angular momentum problem are discussed.

  13. Indian draught animals power

    Directory of Open Access Journals (Sweden)

    K. L. Phaniraja

    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.

  14. Social network analysis in encouraging role-players in the beef market to take breeding decisions: a methodological study

    Directory of Open Access Journals (Sweden)

    Gaetano Martino


    Full Text Available The aim of the research is to apply the social network analysis (SNA to the Italian Romagnola beef meat market in order to better understand the interrelationships of the supply chain. Knowledge of the market exchange system is very important in order to be able to choose the most suitable breeding approach. The analysis was carried out using data concerning the heifers exchanged during the year 2008 within the framework of the activities of the Italian consortium of white bullock producers of the central Apennine region of Italy (Vitellone Bianco dell’Appennino Centrale. The social network analysis shows that very few of the possible links between the agents are used and that this leads to a lack of competitiveness. At the same time, the agents have shown themselves able to place themselves at the most important points along the supply chain. Furthermore, the results of the analysis show the need for a stronger farming phase with a greater emphasis on the farmers, given that, from an economic point of view, they are the most important role-players.

    Stojanovska-Dimzoska Biljana


    Full Text Available Liquid chromatography - fluorescence detector and fluorometry (fluorescence spectrometry with previous immunoaffinity column clean-up, are two methods that are compared in order to evaluate their performances in determination of total aflatoxins content in feed. Method validation was established, linearity of the methods was checked, and a good coefficient of correlation was found for bought methods (0,9994 and 0,978 respectively. The limits of detection were 0,003 ng/ml (average for HPLC-FD method and 0,12 ng/ml for fluorometry. The accuracy of the methods was determined using reference materials with known concentration and spiked aflatoxins free samples. The recoveries were found to be 85,82% (average for HPLC-FD method and 56,75%, for fluorometry. Twenty feed concentrates for bullock and 20 feed concentrates for swine, were analyzed parallel with bought methods. The results are in correlation only in higher concentration range. For lower concentration range (below 1,0 μg/kg fluorometry shows limited sensitivity and selectivity. It was found that it is applicable only as a screening method for the prediction of aflatoxins. HPLC-FD method remains a method of choice for the analyst in order to achieved accurate and reliable results.

Our results confirm that the average halo concentration declines monotonically with mass; a power-law fits well the concentration-mass relation for over 3 decades in mass, up to the most massive objects to form in a LCDM universe (~ 10^15 h^-1 Msol). This is in clear disagreement with the predictions of the model proposed by Bullock et al. for these rare objects, and agrees better with the original predictions of Navarro, Frenk, & White. The large volume surveyed, together with the unprecedented numerical resolution of the MS, allow us to estimate with confidence the distribution of concentrations and, consequently, the abundance of systems with unusual properties. About one in a hundred cluster haloes (M200 >~ 3x10^14 h^-1 Msol) have concentrations exceeding c200 = 7.5, a result that may be used to interpret the likelihood of unusually strong massive gravitational lenses, such as Abell 1689, in the LCDM co...

  19. On Universal Gate Libraries and Generic Minimal Two-qubit Quantum Circuits

    CERN Document Server

    Shende, V V; Bullock, S S; Shende, Vivek V.; Markov, Igor L.; Bullock, Stephen S.


    We show how to implement exactly an arbitrary two-qubit unitary operation in several universal gate libraries using the smallest possible number of gates. To this end, we prove that n-qubit circuits using CNOT and one-qubit gates require at least ceil((4^n - 3n -1)/4) CNOT gates in the worst case. For two-qubit operators, this yields a lower bound of three gates, which we match with an upper bound of three gates. Using quantum circuit identities, we improve an earlier lower bound of 17 elementary gates by Bullock and Markov to 18, and their upper bound of 23 elementary gates to 18. We also improve upon the generic circuit with six CNOT gates by Zhang et al. (our circuit uses three), and that by Vidal and Dawson with 11 basic gates (we use 10). Given the available results, it appears that some universal gate libraries are at a disadvantage, at least in the sense that no construction is known to produce smallest possible circuits.

  20. Effects of slaughter weight and carcass electrical stimulation on the quality and palatability of beef from young purebred bulls. (United States)

    Solomon, M B; West, R L; Hentges, J F


    Seventy-eight purebred Angus and Brahman bulls (10 to 18 mo at slaughter) were used to determine the effects of slaughter weight (60, 80, 90 or 100% of the average mature-cow weight for the respective breed) and carcass electrical stimulation (500 V, 20 2-s impulses on the right side) on carcass and meat characteristics. Angus bulls grazed summer forage (millet) after weaning, while Brahman bulls were fed to stimulate gains achieved on forage by Angus bulls. Bulls were then placed in the feedlot for finishing to their designated slaughter weight (293, 381, 412 and 463 kg for Angus and 316, 420, 463 and 516 kg for Brahman). Coarse dark band formation and lean color problems normally associated with bullock carcasses were either eliminated or reduced by stimulation. Increasing slaughter weight from 60 to 90% was associated with an increase in panel tenderness scores for loin steaks. However, increasing slaughter weight from 90 to 100% little change was detected. On the other hand, shear values for loin steaks decreased with increasing slaughter weight. Stimulation increased the tenderness of loin steaks as determined by both panel scores and shear values, and of bottom round steaks (shear-force values). The data from this study suggest that meat from the bulls slaughtered at lighter weights was generally tough, but was improved when bulls were fed to heavier, yet acceptable weights. This research encourages implementation of electrical stimulation on carcasses from young bulls to improve quality-indicating factors.

  1. Dwarf Dark Matter Halos

    CERN Document Server

    Colin, Pierre; Valenzuela, O; Gottlöber, S


    We use N-body simulations to study properties of dwarf halos with virial masses in the range 10^7-10^9 Msun/h. Unlike recent reported results, we find that the density profiles of relaxed dwarf halos are well fitted by the NFW profile and do not have cores. We estimate the distribution of concentrations for halos in mass range that covers six orders of magnitude from 10^7 Msun/h to 10^13 Msun/h, and find that the data are well reproduced by the model of Bullock et al. (2001). We predict that present-day isolated dwarf halos should have a very large median concentration of ~ 35. For halos with masses that range from 4.6 x 10^9 Msun/h to 10^13 Msun/h we measure the subhalo circular velocity function and find that they are similar when normalized to the circular velocity of the parent halo. We compute the halo mass function and the halo spin parameter distribution and find that the former is very well reproduced by the Sheth and Tormen model while the latter is well fitted by a lognormal distribution with lambda...

  3. The Hohmann-Parker Effect and its Consequences Measured by the Mars Science Laboratory on the Transfer from Earth to Mars (United States)

    Posner, A.; Odstrcil, D.; MacNeice, P. J.; Rastaetter, L.; Zeitlin, C. J.; Elliott, H. A.; Frahm, R. A.; Hayes, J. J.; von Rosenvinge, T. T.; Christian, E. R.; Andrews, J.; Brinza, D.; Epperly, M. E.; Neal, K.; Seimetz, L.; Smith, K. D.; Tyler, Y.; Weigle, E.


    We show that a spacecraft launched from Earth towards Mars following a Hohmann minimum energy transfer trajectory has a strong tendency to remain well-connected magnetically to Earth, in the early phase of the transfer, or to Mars in the late phase, via the Parker spiral magnetic field. On the return trip, the spacecraft would remain reasonably well-connected first to Mars and later to Earth. Moreover, good magnetic connectivity occurs on all Hohmann transfers between neighboring planets in the inner solar system out to Mars. We call this hitherto unnamed circumstance the Hohmann-Parker effect. We show consequences of the effect by means of simultaneous cosmic radiation proxy observations made near Earth, near Mars, and at the Mars Science Laboratory on the transfer from Earth to Mars in 2011/2012. We support the observations with simulations of the large-scale magnetic field of the inner heliosphere during this period and compare the results with our predictions. The implications of the Hohmann-Parker effect are discussed. MSL RAD Science Team: R. Beaujean, S. Boettcher, M. Bullock, S. Burmeister, F. A. Cucinotta, B. Ehresmann, D. Grinspoon, J. Guo, D. M.

    We present a general methodology for determining the gamma-ray flux from annihilation of dark matter particles in Milky Way satellite galaxies, focusing on two promising satellites as examples: Segue 1 and Draco. We use the SuperBayeS code to explore the best-fitting regions of the Constrained Minimal Supersymmetric Standard Model (CMSSM) parameter space, and an independent MCMC analysis of the dark matter halo properties of the satellites using published radial velocities. We present a formalism for determining the boost from halo substructure in these galaxies and show that its value depends strongly on the extrapolation of the concentration-mass (c(M)) relation for CDM subhalos down to the minimum possible mass. We show that the preferred region for this minimum halo mass within the CMSSM with neutralino dark matter is ∼ 10{sup −9}–10{sup −6} M{sub s}un. For the boost model where the observed power-law c(M) relation is extrapolated down to the minimum halo mass we find average boosts of about 20, while the Bullock et al (2001) c(M) model results in boosts of order unity. We estimate that for the power-law c(M) boost model and photon energies greater than a GeV, the Fermi space-telescope has about 20% chance of detecting a dark matter annihilation signal from Draco with signal-to-noise greater than 3 after about 5 years of observation.

  5. Assessment of an oxfendazole pulsed release bolus for control of parasitic gastroenteritis in calves in a rotational grazing system. (United States)

    Mitchell, G B


    A group of 71 Friesian bullocks, aged six to nine months, vaccinated against lungworm, were randomly allocated on a liveweight basis to two groups of 40 and 31 animals. At turn-out each calf in the group of 40 calves was dosed orally with a pulsed release bolus designed to deliver five doses of oxfendazole at regular intervals during a period of up to 130 days, the first dose being released about 21 days after administration. The group treated with the bolus grazed 2.4 ha and the control group grazed 3.6 ha of permanent pasture for six weeks before having additional access to similar areas of silage aftermath. The control group was treated 99 days after turn-out and when they were housed with fenbendazole (7.5 mg/kg). Faecal worm egg counts, plasma pepsinogen activities, pasture larval counts and liveweights were recorded fortnightly. Significant reductions in worm egg counts and plasma pepsinogen activities were recorded in the calves dosed with the pulsed release bolus together with significant improvements in the liveweight of younger calves compared with control animals. Pasture larval counts were lower in the fields grazed by animals treated with the bolus.

  6. Lode-gold mineralization in the Tanami region, northern Australia (United States)

    Huston, David L.; Vandenberg, Leon; Wygralak, Andrew S.; Mernagh, Terrence P.; Bagas, Leon; Crispe, Andrew; Lambeck, Alexis; Cross, Andrew; Fraser, Geoff; Williams, Nick; Worden, Kurt; Meixner, Tony; Goleby, Bruce; Jones, Leonie; Lyons, Pat; Maidment, David


    The Tanami region of northern Australia has emerged over the last two decades as the largest gold-producing region in the Northern Territory. Gold is hosted by epigenetic quartz veins in sedimentary and mafic rocks, and by sulfide-rich replacement zones within iron formation. Although limited, geochronological data suggest that most mineralization occurred at about 1,805-1,790 Ma, during a period of extensive granite intrusion, although structural relationships suggest that some deposits predate this period. There are three main goldfields in the Tanami region: the Dead Bullock Soak goldfield, which hosts the world-class Callie deposit; The Granites goldfield; and the Tanami goldfield. In the Dead Bullock Soak goldfield, deposits are hosted by carbonaceous siltstone and iron formation where a late (D5) structural corridor intersects an early F1 anticlinorium. In The Granites goldfield, deposits are hosted by highly sheared iron formation and are interpreted to predate D5. The Tanami goldfield consists of a large number of small, mostly basalt-hosted deposits that probably formed at a high structural level during D5. The D5 structures that host most deposits formed in a convergent structural regime with σ 1 oriented between E-W and ENE-WSW. Structures active during D5 include NE-trending oblique thrust (dextral) faults and ESE-trending (sinistral) faults that curve into N- to NNW-trending reverse faults localized in supracrustal belts between and around granite complexes. Granite intrusions also locally perturbed the stress field, possibly localizing structures and deposits. Forward modeling and preliminary interpretations of reflection seismic data indicate that all faults extend into the mid-crust. In areas characterized by the N- to NW-trending faults, orebodies also tend to be N- to NW-trending, localized in dilational jogs or in fractured, competent rock units. In areas characterized by ESE-trending faults, the orebodies and veins tend to strike broadly east

Thirty steers, aged at 28 month-bullocks were selected to measure the IMF content in L. Dorsi. Two groups of bullocks (three heads per group) with the highest and the lowest contents of IMF were selected to build a RNA pool, and DEGs of two groups were analyzed by ACP system. Twelve DEGs were identified and sequenced by amplification with 20 arbitrary primers (fragment sizes were 200-890 bp). In these genes, eight were already known as functional groups of cytoskeleton, cytokine signal transduction, protein synthesis, energy metabolismand, and others, four were unknown. All the 12 ESTs were screened by ACP system, which may participated in regulating on lipidosis in muscle. This study established a foundation for further screening of lipidosis related genes.

  8. A naturalistic study of children and their parents in family learning courses in science (United States)

    Ostlund, Karen; Gennaro, Eugene; Dobbert, Marion

    During the 1960s and 1970s a number of family learning projects evolved, most of which focused on pre-schoolers and their parents. The goal of some of these programs was to provide enjoyable, structured experiences in which parents and their children learned together. Recently, a number of institutions have been sponsoring enrichment science classes or learning experiences for parents and older children. The study described here is based on a project funded by the National Science Foundation (DISE No. 07872) which was attempting to show that it was possible to increase scientific literacy of two different age groups by simultaneously exposing parents and their middle school children to short courses in science. The project is an outgrowth of a study previously reported (Gennaro, Bullock, & Alden, 1980) carried out at the Minnesota Zoological Gardens. The study is based on data obtained during the first two years of the project and used various data gathering procedures such as the use of questionnaires, interviews, observations, and cognitive testing. It was found that children register for the courses primarily because of interest in the subject matter of the courses and that parents register because of their desire to nurture the child and the child's interest in the subject matter of the course. Both parents and children made significant gains in learning as measured by subject matter tests. Participants reported that the experience was both enjoyable and valuable. Children's attitudes toward their parents and the course were significantly higher if the children perceived a highly cooperative learning environment with their parents. Parents who scored in the medium or high range on the pretest had significantly more interactions with their children concerning information about course tasks than those who scored low on the pretest.

    The safety of many African traditional herbal remedies is doubtful due to lack of standardization. This study therefore attempted to standardize two polyherbal formulations from Ogbomoso, Oyo State, Nigeria, with respect to the relative proportions (weight-for-weight) of their botanical constituents. Information supplied by 41 local herbal practitioners was statistically screened for consistency and then used to quantify the composition of antimalarial (Maloff-HB) and haematinic (Haematol-B) powdered herbal formulations with nine and ten herbs, respectively. Maloff-HB contained the stem bark of Enantia chlorantha Oliv. (30.0), Alstonia boonei De Wild (20.0), Mangifera indica L. (10.0), Okoubaka aubrevillei Phelleg & Nomand (8.0), Pterocarpus osun Craib (4.0), root bark of Calliandra haematocephala Hassk (10.0), Sarcocephalus latifolius (J. E. Smith) E. A. Bruce (8.0), Parquetina nigrescens (Afz.) Bullock (6.0), and the vines of Cassytha filiformis L. (4.0), while Haematol-B was composed of the leaf sheath of Sorghum bicolor Moench (30.0), fruit calyx of Hibiscus sabdariffa L. (20.0), stem bark of Theobroma cacao L. (10.0), Khaya senegalensis (Desr.) A. Juss (5.5), Mangifera indica (5.5), root of Aristolochia ringens Vahl. (7.0), root bark of Sarcocephalus latifolius (5.5), Uvaria chamae P. Beauv. (5.5), Zanthoxylum zanthoxyloides (Lam.) Zepern & Timler (5.5), and seed of Garcinia kola Heckel (5.5). In pursuance of their general acceptability, the two herbal formulations are recommended for their pharmaceutical, phytochemical, and microbial qualities.

  10. Probing the Anisotropy of the Milky Way Gaseous Halo-II: Sightline toward Mrk 509 (United States)

    Gupta, A.; Mathur, S.; Krongold, Y.


    Hot, million degree gas appears to pervade the Milky Way halo, containing a large fraction of the Galactic missing baryons. This circumgalactic medium (CGM) is probed effectively in X-rays, both in absorption and in emission. The CGM also appears to be anisotropic, so we have started a program to determine CGM properties along several sightlines by combining absorption and emission measurements. Here we present the emission measure close to the Mrk 509 sightline using new Suzaku and XMM-Newton observations. We also present new analysis and modeling of Chandra HETG spectra to constrain the absorption parameters. The emission measure in this sightline is high, EM = 0.0165 ± 0.0008 ± 0.0006 cm‑6 pc, five times larger than the average. The observed O vii column density N(O vii) = 2.35+/- 0.4× {10}16 cm‑2, however, is close to the average. We find that the temperature of the emitting and absorbing gas is the same: logT(K) = 6.33 ± 0.01 and logT(K) = 6.33 ± 0.16 respectively. We fit the observed column density and emission measure with a β-model density profile. The central density is constrained to be between n 0 = 2.8–6.0 × 10‑4 cm‑3 and the core radius of the density profile has a lower limit of 40 kpc. This shows that the hot gas is mostly in the CGM of the galaxy, not in the Galactic disk. Our derived density profile is close to the Maller & Bullock profile for adiabatic gas in hydrostatic equilibrium with an NFW dark-matter potential well. Assuming this density profile, the minimum mass of the hot CGM is 3.2× {10}10 M ⊙.

    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.

  12. The kinetic Sunyaev-Zel'dovich tomography - II. Probing the circumgalactic medium (United States)

    Shao, Jiawei; Fang, Taotao


    We propose the use of the kinetic Sunyaev-Zel'dovich (kSZ) effect to probe the circumgalactic medium (CGM), with the aid of a spectroscopic survey covering the same area of a SZ survey. It is possible to design an optimal estimator of the kSZ effect of the CGM with a matched filter, and to construct the cross-correlation between the estimator and the peculiar velocity recovered from the galaxy survey, which can be measured by stacking a number of galaxies. We investigate two compelling profiles for the CGM - the Maller-Bullock (MB) profile and the β profile - and we estimate the detectability against the synergy of a fiducial galaxy survey with number density 10-3 h3 Mpc-3 and an Atacama Cosmology Telescope-like SZ survey. We show that the shape of the filter does not change much with redshift for the β profile, while there are significant side lobes at z < 0.1 for the MB profile. By stacking ˜104 Milky Way-size haloes around z ˜ 0.5, we can obtain ≳1σ signal-to-noise ratio (S/N) for both profiles. The S/N increases with decreasing redshift before it reaches a maximum (˜7.5 at z ≃ 0.12 for the MB profile and ˜19 at z ≃ 0.03 for the β profile). Because of the large beam size, a Planck-like cosmic microwave background survey can marginally detect the kSZ signal by stacking the same number of galaxies at z < 0.1. The search for the CGM in realistic surveys will involve dividing the galaxies into subsamples with similar redshift and mass of host haloes, and scaling the results presented here to obtain the S/N.

  15. The pairwise velocity difference of over 2000 BHB stars in the Milky Way halo

    Institute of Scientific and Technical Information of China (English)

    Xiang-Xiang Xue; Hans-Walter Rixm; Gang Zhao


    Models of hierarchical galaxy formation predict that the extended stellar halos of galaxies like our Milky Way show a great deal of sub-structure,arising from disrupted satellites.Spatial sub-structure is directly observed,and has been quantified,in the Milky Way's stellar halo.Phase-space conservation implies that there should be sub-structure in position-velocity space.Here,we aim to quantify such position-velocity sub-structure,using a state-of-the art data set having over 2000 blue horizontal branch (BHB) stars with photometry and spectroscopy from SDSS.For stars in dynamically cold streams ("young"streams),we expect that pairs of objects that are physically close also have similar velocities.Therefore,we apply the well-established "pairwise velocity difference" (PVD)statistic (△r),where we expect to drop for small separations △r.We calculate the PVD for the SDSS BHB sample and find (△r)≈ const., such signal.By making mock-observations of the simulations by Bullock & Johnston and applying the same statistic,we show that for individual,dynamically young streams,or assemblages of such streams,drops for small distance separations △r,as qualitatively expected.However,for a realistic complete set of halo streams,the pair-wise velocity difference shows no signal,as the simulated halos are dominated by "dynamically old" phase-mixed streams.Our findings imply that the sparse sampling and the sample sizes in SDSS DR6 are still insufficient to use the position-velocity sub-structure for a stringent quantitative data-model comparison.Therefore,alternate statistics must be explored and much more densely sampled surveys,dedicated to the structure of the Milky Way,such as LAMOST,are needed.

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.

  18. The redshift dependence of the structure of massive Λ cold dark matter haloes (United States)

    Gao, Liang; Navarro, Julio F.; Cole, Shaun; Frenk, Carlos S.; White, Simon D. M.; Springel, Volker; Jenkins, Adrian; Neto, Angelo F.


    We use two very large cosmological simulations to study how the density profiles of relaxed Λ cold dark matter dark haloes depend on redshift and on halo mass. We confirm that these profiles deviate slightly but systematically from the NFW form and are better approximated by the empirical formula, d logρ/d logr ~ rα, first used by Einasto to fit star counts in the Milky Way. The best-fitting value of the additional shape parameter, α, increases gradually with mass, from α ~ 0.16 for present-day galaxy haloes to α ~ 0.3 for the rarest and most massive clusters. Halo concentrations depend only weakly on mass at z = 0, and this dependence weakens further at earlier times. At z ~ 3 the average concentration of relaxed haloes does not vary appreciably over the mass range accessible to our simulations (M >~ 3 × 1011h-1Msolar). Furthermore, in our biggest simulation, the average concentration of the most massive, relaxed haloes is constant at ~ 3.5-4 for 0 Frenk & White. With their original parameters, the NFW prescription overpredicts halo concentrations at high redshift. This shortcoming can be reduced by modifying the definition of halo formation time, although the evolution of the concentrations of Milky Way mass haloes is still not reproduced well. In contrast, the much-used revisions of the NFW prescription by Bullock et al. and Eke, Navarro & Steinmetz predict a steeper drop in concentration at the highest masses and stronger evolution with redshift than are compatible with our numerical data. Modifying the parameters of these models can reduce the discrepancy at high masses, but the overly rapid redshift evolution remains. These results have important implications for currently planned surveys of distant clusters.

  19. Complex Engineered Systems: A New Paradigm (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.

  1. Joint Multifractal Analysis of penetration resistance variability in an olive orchard. (United States)

    Lopez-Herrera, Juan; Herrero-Tejedor, Tomas; Saa-Requejo, Antonio; Villeta, Maria; Tarquis, Ana M.


    Spatial variability of soil properties is relevant for identifying those zones with physical degradation. We used descriptive statistics and multifractal analysis for characterizing the spatial patterns of soil penetrometer resistance (PR) distributions and compare them at different soil depths and soil water content to investigate the tillage effect in soil compactation. The study was conducted on an Inceptisol dedicated to olive orchard for the last 70 years. Two parallel transects of 64 m were selected as different soil management plots, conventional tillage (CT) and no tillage (NT). Penetrometer resistance readings were carried out at 50 cm intervals within the first 20 cm of soil depth (López de Herrera et al., 2015a). Two way ANOVA highlighted that tillage system, soil depth and their interaction are statistically significant to explain the variance of PR data. The comparison of CT and NT results at different depths showed that there are significant differences deeper than 10 cm but not in the first two soil layers. The scaling properties of each PR profile was characterized by τ(q) function, calculated in the range of moment orders (q) between -5 and +5 taken at 0.5 lag increments. Several parameters were calculated from this to establish different comparisons (López de Herrera et al., 2015b). While the multifractal analysis characterizes the distribution of a single variable along its spatial support, the joint multifractal analysis can be used to characterize the joint distribution of two or more variables along a common spatial support (Kravchenko et al., 2000; Zeleke and Si, 2004). This type of analysis was performed to study the scaling properties of the joint distribution of PR at different depths. The results showed that this type of analysis added valuable information to describe the spatial arrangement of depth-dependent penetrometer data sets in all the soil layers.

  5. The statistics of Λ CDM halo concentrations (United States)

    Neto, Angelo F.; Gao, Liang; Bett, Philip; Cole, Shaun; Navarro, Julio F.; Frenk, Carlos S.; White, Simon D. M.; Springel, Volker; Jenkins, Adrian


    We use the Millennium Simulation (MS) to study the statistics of Λ cold dark matter (ΛCDM) halo concentrations at z = 0. Our results confirm that the average halo concentration declines monotonically with mass; the concentration-mass relation is well fitted by a power law over three decades in mass, up to the most massive objects that form in a ΛCDM universe (~ 1015h-1Msolar). This is in clear disagreement with the predictions of the model proposed by Bullock et al. for these rare objects, and agrees better with the original predictions of Navarro, Frenk & White. The large volume surveyed, together with the unprecedented numerical resolution of the MS, allows us to estimate with confidence the distribution of concentrations and, consequently, the abundance of systems with unusual properties. About one in a hundred cluster haloes (M200 >~ 3 × 1014h-1Msolar) have concentrations exceeding c200 = 7.5, a result that may be useful in interpreting the likelihood of unusually strong massive gravitational lenses, such as Abell 1689, in the ΛCDM cosmogony. A similar fraction of about 1 per cent of galaxy-sized haloes (M200 ~ 1012h-1Msolar) have c200 < 4.5 and this could be relevant to models that attempt to reconcile the ΛCDM cosmology with rotation curves of low surface brightness galaxies by appealing to haloes of unexpectedly low concentration. We find that halo concentrations are independent of spin once haloes manifestly out of equilibrium have been removed from the sample. Compared to their relaxed brethren, the concentrations of out-of-equilibrium haloes tend to be lower and have more scatter, while their spins tend to be higher. A number of previously noted trends within the halo population are induced primarily by these properties of unrelaxed systems. Finally, we compare the result of predicting halo concentrations using the mass assembly history of the main progenitor with predictions based on simple arguments regarding the assembly time of all progenitors

    The 2011 National Beef Quality Audit (NBQA-2011) assessed the current status of quality and consistency of fed steers and heifers. Beef carcasses (n = 9,802), representing approximately 10% of each production lot in 28 beef processing facilities, were selected randomly for the survey. Carcass evaluation for the cooler assessment of this study revealed the following traits and frequencies: sex classes of steer (63.5%), heifer (36.4%), cow (0.1%), and bullock (0.03%); dark cutters (3.2%); blood splash (0.3%); yellow fat (0.1%); calloused rib eye (0.05%); overall maturities of A (92.8%), B (6.0%), and C or greater (1.2%); estimated breed types of native (88.3%), dairy type (9.9%), and Bos indicus (1.8%); and country of origin of United States (97.7%), Mexico (1.8%), and Canada (0.5%). Certified or marketing program frequencies were age and source verified (10.7%), ≤A(40) (10.0%), Certified Angus Beef (9.3%), Top Choice (4.1%), natural (0.6%), and Non-Hormone-Treated Cattle (0.5%); no organic programs were observed. Mean USDA yield grade (YG) traits were USDA YG (2.9), HCW (374.0 kg), adjusted fat thickness (1.3 cm), LM area (88.8 cm2), and KPH (2.3%). Frequencies of USDA YG distributions were YG 1, 12.4%; YG 2, 41.0%; YG 3, 36.3%; YG 4, 8.6%; and YG 5, 1.6%. Mean USDA quality grade (QG) traits were USDA quality grade (Select(93)), marbling score (Small(40)), overall maturity (A(59)), lean maturity (A(54)), and skeletal maturity (A(62)). Frequencies of USDA QG distributions were Prime, 2.1%; Choice, 58.9%; Select, 32.6%; and Standard or less, 6.3%. Marbling score distribution was Slightly Abundant or greater, 2.3%; Moderate, 5.0%; Modest, 17.3%; Small, 39.7%; Slight, 34.6%; and Traces or less, 1.1%. Carcasses with QG of Select or greater and YG 3 or less represented 85.1% of the sample. This is the fifth benchmark study measuring targeted carcass characteristics, and information from this survey will continue to help drive progress in the beef industry. Results will

    Background: The plant species Bursera copallifera (DC) bullock is used in traditional medicine to treat inflammation. The leaves of this plant can be prepared as an infusion to treat migraines, bronchitis, and dental pain Objective: The purpose of this study was to determine the anti-inflammatory and cytotoxic activities of organic extracts from the stems, stem bark, and leaves of B. copallifera, which was selected based on the knowledge of its traditional use. Materials and Methods: We evaluated the ability of extracts to inhibit mouse ear inflammation in response to topical application of 12-O tetradecanoylphorbol-13-acetate. The extracts with anti-inflammatory activity were evaluated for their inhibition of pro-inflammatory enzymes. In addition, the in vitro cytotoxic activities of the organic extracts were evaluated using the sulforhodamine B assay. Results: The hydroalcoholic extract of the stems (HAS) exhibited an anti-inflammatory activity of 54.3% (0.5 mg/ear), whereas the anti-inflammatory activity of the dichloromethane-methanol extract from the leaves (DMeL) was 55.4% at a dose of 0.1 mg/ear. Methanol extract from the leaves (MeL) showed the highest anti-inflammatory activity (IC50 = 4.4 μg/mL), hydroalcoholic extract of leaves, and DMeL also reduce the enzyme activity, (IC50 = 6.5 μg/mL, IC50 = 5.7 μg/mL), respectively, from stems HAS exhibit activity at the evaluated concentrations (IC50 =6.4 μg/mL). The hydroalcoholic extract of the stems exhibited the highest cytotoxic activity against a breast adenocarcinoma cell line (MCF7, IC50 = 0.90 μg/mL), whereas DMeL exhibited an IC50 value of 19.9 μg/mL. Conclusion: In conclusion, extracts from leaves and stems inhibited cyclooxygenase-1, which is the target enzyme for nonsteroidal anti inflammatory drugs, and some of these extracts demonstrated substantial antiproliferative effects against the MCF7 cell line. These results validate the traditional use of B. copallifera. PMID:26664022

  11. Mineralogy and geochemistry of the Jurassic coals from the Gheshlagh mine, Eastern Alborz

    Directory of Open Access Journals (Sweden)

    Gholam Hossein Shamanian


    Full Text Available Introduction The Alborz structural zone in northern Iran is the host of a number of important coal deposits. The Gheshlagh coal mine is one of them, which is located 35 km southeast of Azadshahr. Coal bearing strata in the Gheshlagh mining district occur in the middle part of the Lower Jurassic Shemshak Formation which consists mainly of shales, siltstones and sandstones. The Geshlagh coals have a low sulfur content and a low ash yield. The ash content of coal and its geochemical character depends on the environment of deposition and subsequent geological history (Yazdi and Esmaeilnia, 2004. The purpose of this study was to investigate the texural and mineralogical characteristcs of the Ghashlagh coals and to identify the geochemistry of the major and trace elements and their relationship to specific mineralogical components. These results are necessary to improve the understanding of coal characterization and to relate the mineralogy of different materials to their potential for producing acidic or alkaline mine waters associated with mining and preparation processes. Materials and methods About 20 samples were collected from the main coal seams. These samples were taken from fresh faces of the mine to avoid weathered surfaces and get fresh samples. The petrography of the samples was carried out by the conventional microscopic methods at the Golestan University. Mineralogical analyses were done by a X-ray diffractometer equipped with a CuKα tube and monochrometer (XRD Philips PW 1800 at the Kansaran Binaloud Company. The coal samples were initially crushed to less than 200 μm and homogenized. Then, 50 g from each sample was heated to 525 oC according to the United States Geological Survey procedure(Bullock et al., 2002. The concentration of the major and trace elements in the resulting ash samples was determined using a wavelength Xray fluorescence spectrometer (XRF Philips PW1480 at the Kansaran Binaloud Company.

    Uncontrolled harvesting of non-timber forest products (NTFPs) poses a serious risk of extermination to several of these species in Nigeria.Yet,there is a paucity of information on the distribution,population status and sustainable management of NTFPs in most of the tropical lowland rainforests.We,therefore,assessed the population,distribution and threats to sustainable management of NTFPs within the tropical lowland rainforests of Omo and Shasha Forest Reserves,south western Nigeria.Data were obtained through inventory surveys on five top priority species including:bush mango (Irvingia gabonensis (Aubry-Lecomte ex O'Rorke) Baill),African walnut (Tetracarpidium conophorum (Mull.Arg.) Hutch.& Dalziel syn.Plukenetia conophora),chew-stick (Massularia acuminata (G.Don) Bullock),fever bark (Annickia chlorantha Setten & P.J.Maas syn.Enantia chloranta) and bush pepper (Piper guineense Schumach.& Thonn.).Purposive and stratified random sampling techniques were used for the inventory.Each forest reserve was stratified into three,viz:less disturbed natural forest (for areas that have been rested for at least ten years),recently disturbed natural forest (for areas that have suffered one form of human perturbation or the other in the last five years),and plantation forest (for areas carrying forest plantation).Data were collected from eighteen 10 m ×500 m belt transects located in the above strata.The species were generally fewer in both plantation and recently disturbed natural forest than the less disturbed natural forest,suggesting that forest disturbances (habitat modification) for other uses may have an effect on the occurrence and densities of the NTFPs.Exceptions to this trend were found for P.guineense and T.conophorum,which were fairly common in both plantation and recently disturbed natural forest.Among three tree NTFP species (i.e.I.gabonensis,M.acuminata and A.chlorantha),only I.gabonensis showed a significant difference in overall DBH size classes for both

    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.

    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

  16. Chemical reactions between Venus' surface and atmosphere - An update. (Invited) (United States)

    Treiman, A. H.


    hypothetical early Venus with a water-rich atmosphere. Martin et al. [13] investigated the fate of weathered rock when heated (by igneous or impact events). Our understanding of Venus' geological history is stymied by a lack of data - spacecraft observations of and/or at its surface. VMC on VEx may continue to provide new data on surface emissivity, but their interpretation is inherently ambiguous. Laboratory experiments seem the most promising approach - attempting to quantify rates of weathering and thus volcanism [3], and (with luck) framing significant problems that can be directly answered by spacecraft observations.

    In order to detect cotton’s position on a plant, a laser measurement experiment was designed, which included a crossgirder, and beneath which a model LMS291-S05 laser scanner produced by SICK Co., Ltd was fixed. Then the three-dimensional coordinate values of a single cotton plant can be measured with the devices mentioned above, and the acquired distance image was furthermore processed with computer image processing technology and pattern recognition theory and also with the agronomic characteristics of cotton taken into consideration. The sampling interval of the laser sensor on axis X and axis Y was both 0.004 m, and the sampled points formed a image that illustrated the distance from the laser sensor to the plant surface point cloud. For the purpose of removing the unneeded background of the plant in the image, the acquired plant distance image was first processed with binaryzation at the threshold value of 0.9 m, because that 0.9 m happened to be the longest distance from the laser sensor to the bottom part of the cotton plant surface according to the measured data. Observing the cotton plant’s morphological characters in the formerly binarized image, and it was not hard to find out that the cotton part in the image appeared to be circular with a large area, while the stalk part in the image was thin and tiny. On this basis, morphology opening operations were carried out toward the edge of the bimarized image with the structural elements from a circle whose radius ranges from 0.01 m to 0.02 m, which is the usual width of a cotton stalk, in order to remove the unneeded cotton stalk background and extract the binary image of cotton. After a series of comparisons among different distances namely Euclidean, Mahalanobis, Bullock, and Minkowski distances, and considering that the pixel gray value was one-dimensional data, the distance between pixels was found to be insensitive to computing methods. The similarity between pixels in the image was calculated with

  1. EDITORIAL: Environmental justice: a critical issue for all environmental scientists everywhere (United States)

    Stephens, Carolyn


    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.

  2. Comparative Climatology of Terrestrial Planets (United States)

    Mackwell, Stephen J.; Simon-Miller, Amy A.; Harder, Jerald W.; Bullock, Mark A.

    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.
