    Wood, S F

    1989-01-01

    The range of treatments for hay fever available to the general practitioner has changed considerably in recent years. New antihistamines have addressed the problem of sedation and moved towards one daily dose; nasally applied corticosteroids avoid the need for systemic steroid therapy and its potential adverse effect; and regulatory decisions have set a trend away from immunotherapy in general practice. However, knowledge about the mechanism of action of immunotherapy is increasing and new developments with improved safety profiles include allergen polymers, allergoids, oral immunotherapy and nasal immunotherapy. Choice of treatment depends, as always, on the individual circumstances of the patient and his or her disease. PMID:2556545

    2013-01-01

    The oxidative Glaser–Hay coupling of two terminal alkynes to furnish a butadiyne is a key reaction for acetylenic scaffolding. Although the reaction is performed under rather simple conditions [CuCl/TMEDA/O2 (air)], the mechanism is still under debate. Herein we present detailed studies...... on the scope of this reaction by using both 13C NMR and UV/Vis spectroscopic methods. The former method was used to study the kinetics of the coupling of aryl-substituted alkynes as the aryl carbon resonances of the reactants and products have similar NOEs and relaxation times. The reaction was found...... to be zero-order with respect to the terminal alkyne reactant under standard preparative conditions. Moreover, as the reaction proceeded, a clear change to slower reaction kinetics was observed, but it was still apparently zero-order. The onset of this change was found to depend on the catalyst loading...

    Full Text Available El turismo que se basa en su entorno natural es responsable por aproximadamente el 40% de los ingresos de turismo y es un mercado en crecimiento. Sin embargo, el turismo ha sido una actividad que ha generado graves impactos ambientales y sociales a nivel mundial. En el contexto ambiental ha transformado áreas de alto valor de conservación en ciudades de cemento y ladrillo, ha contaminado los recursos hídricos, ha erosionado terrenos, ha disminuido los hábitats de muchos animales ante la presencia no planificada de las actividades humanas y ha interrumpido el flujo de especies y de información genética ante la construcción de carreteras, complejos turísticos y otras edificaciones, entre otros impactos. En el contexto social, ha transformado culturalmente a muchas poblaciones locales, sin que hayan tenido la posibilidad y la capacidad de decidir sobre sus mejores opciones económicas y sociales. En muchos casos las poblaciones locales no han tenido la oportunidad, por fallas institucionales y de mercado, de participar activamente en la captura de beneficios de la actividad turística. Estos son ejemplos de los impactos negativos de la globalización cuando no hay la información, la capacidad y la participación ciudadana para la toma de decisión acertadas. Este artículo demuestra, mediante el uso de casos prácticos, cómo un turismo de naturaleza bien manejado, que permita la toma de buenas decisiones por parte de las personas relacionadas directa e indirectamente de sus actividades y que disminuya al máximo sus impactos negativos sociales y ambientales, es una actividad deseable para el desarrollo sostenible de una región y un país como Colombia.

La escritura y el modo de presentación del libro reflejan la textura de la temática y la complejidad del espacio de reflexión. Desde una sociología de los cuerpos y las emociones es posible hallar pistas que nos conduzcan a comprender el sentido que los actores dan a sus prácticas; identificar nodos conflictuales que emergen en esas comprensiones cotidianas; y dar cuenta de cómo la sociedad que se hace cuerpo, puede ser rastreada a partir del análisis de determinadas emociones sociales. Desde el título podemos reconocer que el libro deja huellas para comprender que el propio cuerpo es discusión del presente y del futuro inmediato.

    Seasonal allergic rhinitis (hay fever) is common and can considerably reduce the quality of life of sufferers. Despite the wide everyday application and promising results with homeopathy, scientific evidence of its effectiveness for most ailments is scarce. The assessment of the clinical effectiveness of homeopathic remedies in the alleviation of hay fever symptoms in a typical clinical setting. We performed a clinical observational study of eight patients in the treatment of hay fever symptoms over a two-year period (2012 and 2013) using Measure Yourself Medical Outcome Profile (MYMOP) self-evaluation questionnaires at baseline and again after two weeks and four weeks of homeopathic treatment. The individualized prescription - either a single remedy or multiple remedies - was based on the totality of each patient's symptoms. The average MYMOP scores for the eyes, nose, activity and wellbeing had improved significantly after two and four weeks of homeopathic treatment. The overall average MYMOP profile score at baseline was 3.83 (standard deviation, SD, 0.78). After 14 and 28 days of treatment the average score had fallen to 1.14 (SD, 0.36; PHomeopathy.

En una empresa en compra/venta, los recursos fijos depreciados se transmutan en un medio esencial de entrada, para las adquisiciones -parciales y totales- como modo de entrada. Las teorías de empresa han brindado escasa atención a la influencia sustantiva de los medios de trabajo depreciados, en las adquisiciones como modo de entrada. El rol de medio que desempeñan esos recursos depreciados, es evidente en la historia de las coyunturas de mercado; recesión, depresión, crecimiento y prosperidad. En recesión y depresión, dado el desarrollo de las fuerzas productivas, los medios de trabajo depreciados se tornan en recursos estratégicos. La misión de esos recursos es fortalecer y posicionar a la empresa adquiriente en el mercado global. Los recursos depreciados contribuyen a contrarrestar la tendencia a la baja de la tasa media de ganancia de la empresa adquiriente. Esta investigación busca aportar a las teorías de recursos, un modelo de análisis que contribuya a explicar el papel de medio de entrada de los recursos depreciados, en las adquisiciones como modo de entrada.

  18. The HayWired Earthquake Scenario

    2017-04-24

    ForewordThe 1906 Great San Francisco earthquake (magnitude 7.8) and the 1989 Loma Prieta earthquake (magnitude 6.9) each motivated residents of the San Francisco Bay region to build countermeasures to earthquakes into the fabric of the region. Since Loma Prieta, bay-region communities, governments, and utilities have invested tens of billions of dollars in seismic upgrades and retrofits and replacements of older buildings and infrastructure. Innovation and state-of-the-art engineering, informed by science, including novel seismic-hazard assessments, have been applied to the challenge of increasing seismic resilience throughout the bay region. However, as long as people live and work in seismically vulnerable buildings or rely on seismically vulnerable transportation and utilities, more work remains to be done.With that in mind, the U.S. Geological Survey (USGS) and its partners developed the HayWired scenario as a tool to enable further actions that can change the outcome when the next major earthquake strikes. By illuminating the likely impacts to the present-day built environment, well-constructed scenarios can and have spurred officials and citizens to take steps that change the outcomes the scenario describes, whether used to guide more realistic response and recovery exercises or to launch mitigation measures that will reduce future risk.The HayWired scenario is the latest in a series of like-minded efforts to bring a special focus onto the impacts that could occur when the Hayward Fault again ruptures through the east side of the San Francisco Bay region as it last did in 1868. Cities in the east bay along the Richmond, Oakland, and Fremont corridor would be hit hardest by earthquake ground shaking, surface fault rupture, aftershocks, and fault afterslip, but the impacts would reach throughout the bay region and far beyond. The HayWired scenario name reflects our increased reliance on the Internet and telecommunications and also alludes to the

    Igl, Lawrence D.; Johnson, Douglas H.

    2016-01-01

    The Conservation Reserve Program (CRP) is a voluntary program that is available to agricultural producers to help protect environmentally sensitive or highly erodible land. Management disturbances of CRP grasslands generally are not allowed unless authorized to provide relief to livestock producers during severe drought or a similar natural disaster (i.e., emergency haying and grazing) or to improve the quality and performance of the CRP cover (i.e., managed haying and grazing). Although CRP grasslands may not be hayed or grazed during the primary bird-nesting season, these disturbances may have short-term (1 yr after disturbance) and long-term (≥2 yr after disturbance) effects on grassland bird populations. We assessed the effects of haying on 20 grassland bird species in 483 CRP grasslands in 9 counties of 4 states in the northern Great Plains, USA between 1993 and 2008. We compared breeding bird densities (as determined by total-area counts) in idle and hayed fields to evaluate changes 1, 2, 3, and 4 years after haying. Haying of CRP grasslands had either positive or negative effects on grassland birds, depending on the species, the county, and the number of years after the initial disturbance. Some species (e.g., horned lark [Eremophila alpestris], bobolink [Dolichonyx oryzivorus]) responded positively after haying, and others (e.g., song sparrow [Melospiza melodia]) responded negatively. The responses of some species changed direction as the fields recovered from haying. For example, densities for common yellowthroat (Geothlypis trichas), sedge wren (Cistothorus platensis), and clay-colored sparrow (Spizella pallida) declined the first year after haying but increased in the subsequent 3 years. Ten species showed treatment × county interactions, indicating that the effects of haying varied geographically. This long-term evaluation on the effects of haying on breeding birds provides important information on the strength and direction of changes in

    The purpose of this study was to determine the diurnal composition and concentration of volatile fatty acids (VFA) and to determine VFA composition and concentration differences between stomach compartment 1 (C1) and caecum of alpacas fed grass and alfalfa hay. The study was divided into two experiments. In Experiment 1 (EXP 1), 10 male alpacas (3+ years old, 65 kg BW) were divided into two groups, housed in drylot pens, provided ad libitum water and fed alfalfa (AH) or grass hay (GH) for 30 days. The alpacas were slaughtered and the digestive tract collected, divided into sub-tract sections, weighed and digesta sampled for pH, dry matter (DM) and NDF. Volatile fatty acid composition and concentration were determined on C1 and caecal material. Four adult male (3+ years old, 60 kg BW), C1 fistulated alpacas were housed in metabolism crates and divided into two forage groups for Experiment 2 (EXP 2). Alpacas were fed the forages as in EXP 1. Diurnal C1 VFA samples were drawn at 1, 3, 6, 9, 12, 18 and 24 h post-feeding. There were no differences between forages for tract weight, C1 and caecum digesta DM or NDF. Differences were noted (p alpacas and the diurnal VFA patterns. Composition of VFA is similar to other ruminant species.

    A ciliate protozoa suppression can reduce methane production increasing the energy efficiency utilization by ruminants. The physicochemical characteristics of rumen fluid and the profile of the rumen protozoa populations were evaluated for sheep fed banana leaf hay in replacement of the Cynodon dactylon cv. vaqueiro hay. A total of 30 male sheep were raised in intensive system during 15 days of adaptation and 63 days of experimental period. The animals were distributed in a completely randomized design that included six replicates of five treatments with replacement levels (0, 25, 50, 75, and 100%) of the grass vaquero for the banana leaf hay. Samples of fluid were collected directly from the rumen with sterile catheters. Color, odor, viscosity, and the methylene blue reduction potential (MBRP) were evaluated and pH estimated using a digital potentiometer. After decimal dilutions, counts of genus protozoa were performed in Sedgewick Rafter chambers. The averages of pH, MBRP, color, odor, and viscosity were not influenced by the inclusion of the banana leaf hay. However, the total number of protozoa and Entodinium spp. population significantly decreased at 75 and 100% inclusions of banana leaf hay as roughage.

    On-farm production of hay and high-protein-content feed has several advantages such as diversification of on-farm cultivated crops, reduction of off-farm feed concentrates transported over long distances and a reduction in runoff during the winter season if grown crops are perennial. Among those crops cultivated for high-protein-content feed, alfalfa (Medicago sativa L.) is one of the most important in the Italian context. Nevertheless, up to now, only a few studies have assessed the environmental performance of alfalfa hay production. In this study, using the Life Cycle Assessment approach, the environmental impact of alfalfa hay production in Northern Italy was analyzed. More in detail, two production practices (without and with irrigation) were compared. The results show that alfalfa hay production in irrigated fields has a better environmental performance compared to non-irrigated production, mainly because of the yield increase achieved with irrigation. In particular, for the Climate Change impact category, the impact is equal to 84.54 and 80.21kgCO 2 /t of hay for the scenario without and with irrigation, respectively. However, for two impact categories (Ozone Depletion and Human Toxicity-No Cancer Effect), the impact of irrigation completely offsets the yield increase, and the cultivation practice without irrigation shows the best environmental performance. For both scenarios, the mechanization of harvest is the main environmental hotspot, mostly due to fuel consumption and related combustion emissions. Wide differences were highlighted by comparing the two scenarios with the Ecoinvent process of alfalfa hay production; these differences are mostly due to the cultivation practice and, in particular, to the more intensive fertilization in Swiss production.

    The aim of this study was to evaluate the effect of the inclusion of peanut (Arachis pintoi cv. Amarillo) hay in diets based on dwarf elephant grass (DEG, Pennisetum purpureum Schum cv. Kurumi) hay of different regrowth ages on forage intake and digestibility in wether lambs. The experimental treatments consisted of DEG hay with an interval of regrowth of 30 or 45 days offered as the only feed or in mixture with peanut hay (300 g/kg of total dry matter (DM)), which were tested in eight Texel × Suffolk crossbred wethers in a replicated 4 × 4 Latin square experiment. Both organic matter (OM) and digestible OM intakes were higher (P < 0.05) in animals receiving the legume forage. Total apparent OM digestibility was higher (P < 0.05) at an increased grass regrowth age. Ruminal OM digestibility increased (P < 0.05) with legume inclusion and at a higher grass regrowth age. The nitrogen (N) intake was higher (P < 0.05) in legume treatments and lower (P < 0.05) as the grass regrowth age increased, but retention of N was not affected by treatments. Duodenal flow of both, non-ammonia N and microbial N, were not affected by legume inclusion and were lower (P < 0.05) as grass regrowth age increased. The efficiency of rumen microbial protein synthesis (ERMPS) was negatively affected (P < 0.05) by legume inclusion and was lower (P < 0.05) as the grass regrowth age increased. Supplementation of dwarf elephant grass hay cut at the vegetative stage with peanut legume hay improves nutritional supply to wethers due to an increase in the forage intake.

  8. A different voice: Mary Hays's the Memoirs of Emma Courtney.

    Science.gov (United States)

    Sharma, A

    2001-01-01

    Mary Hays wrote in the decade of the 1790s, a period of intense creative flowering in England. Writing in a period enshrined to the works of the canonical Wordsworth and Coleridge, Hays explored through her Jacobinical novel, The Memoirs of Emma Courtney, the contentious relationship between self and society. Like other Jacobin women writers - Elizabeth Inchbald, Charlotte Smith and Mary Wollstonecraft - Mary Hays too used her novel to explode the insidious connection between education and gender construction. Emma Courtney is a landmark novel that wrestles with the paradigm of decorum and propriety which disallows women from voicing their aspirations. In the process, Hays merges the plots of the domestic novel of courtship and love with the novel of ideas to create a searing portrait of women's intellectual confinement and psychic dissonance in a society that only projects them in terms of their gender construction. Memoirs of Emma Courtney is a remarkable novel in its depiction of the emotional imbalance created by thwarted desire: intellectual and sexual.

    Over two years, replicate plots of lentils (Lens culinaris L.) were treated before seeding with methabenzthiazuron at a rate of 0.5 kg a.i. ha-1. In each year representative soil, lentil and hay samples were randomly collected from plots of each treatment. Soil samples were tested for residues 24 hours after treatment and harvest. Lentil and hay samples were tested at harvest. A cleanup step was conducted after extraction. Gas chromatograph equipped with a nitrogen/phosphorus detector was used to detect methabenzthiazuron. Overall average of residue levels in soil decreased significantly from 1.16+-0.15 mg kg, 24 hours after treatment, 0.12 +-0.01 mg kg at harvest. No significant difference in the maximum average residue was found in lentil and hay samples collected from various plots and tested at harvest (0.10+-0.01 and 0.19 +-0.02 mg kg in lentils and hay, respectively). Recovery tests were conducted with each group of samples tested in order to determine the efficiency of analytical procedure. (author)

    Full Text Available El propósito de este trabajo es reconstruir la línea argumentativa utilizada por la Corte Interamericana de Derechos Humanos en la resolución del caso Gonzales Lluy y otros versus Ecuador, de 1 de septiembre de 2015, conforme la tesis de que la Corte IDH aplica el argumento de igualdad en la versión del examen de proporcionalidad estricto como eje central de su argumentación, dejando de lado un posible argumento basado en el “principio de no regresividad”. Sostengo que la decisión de la Corte IDH se asienta, fundamentalmente, en el trato discriminatorio que sufrió la demandante y su familia al poner en riesgo su vida y su integridad física y su derecho a la educación. Sin embargo, para muchos de los que trabajamos en DESC, el fallo es insuficiente, pues la Corte elude la aplicación del artículo 26 de la Convención Americana de Derechos Humanos (principio de progresividad y no regresividad. La aplicación y el desarrollo de los estándares contenidos en el artículo 26 de la CADH resultan de gran utilidad práctica para los diferentes Estados de la región, generando pautas interpretativas para la exigibilidad de los DESC y otorgando herramientas concretas para evaluar su incumplimiento.

    Full Text Available Hay’s eight Biblical principles for economic lifeDonald Hay used the idea of stewardship to derive eight Biblical principles for economic life. The purpose of this article is to contribute commentary on and criticism of Hay's approach. The eight Biblical principles cover three main issues, namely creation and man's dominion, man and his work, and the distribution of goods. While social principles can be in conflict with each other, Biblical principles ought not to be in conflict. The test to determine whether the principles have been correctly derived is to revert back to the original text constantly. Upon further reflection it is possible to arrive at further applications of Biblical principles in relation to the sphere of economic life.

    The Chevilly Larue/L'Hay les Roses (Paris region, France) low energy geothermal plants are interconnected and thus represent the greatest geothermal heat network in Europe. The two plants are 2.5 km apart and supply 13000 collective lodgings in energy using a 60 km network with a 75 MW power. Gas or fuel auxiliary heating systems are used in winter to increase water temperature up to 105 C, but the part of energy released by geothermics remains of about 70 to 80%. The network will be extended in the next years to Fresnes and Villejuif neighbouring towns. In 1996, the SEMHACH company, which manage the two plants, will put into service a mixed electricity and heat production plant in L'Hay les Roses. (J.S.). 2 photos

La familia tiene, en este entramado, un papel predominante en la provisión de cuidados a las personas ancianas. Por eso, el objetivo del presente trabajo estará dirigido a demostrar algunas acciones que la sociedad cubana ha desarrollado para fortalecer la capacidad de las familias cuando alguno de sus miembros es un adulto mayor. Su desarrollo parte de la hipótesis general de que la familia sola no podrá responder a las múltiples repercusiones que acompañan el proceso de envejecimiento poblacional y necesitarán de una mayor atención social. No hay dudas de que, a escala social, se viene produciendo en el país una redefinición de la vejez en la conciencia de las personas. Ello no quiere decir que todo esté resuelto, sino que hay una mayor sensibilidad y se trabaja para atender una situación que el país ya tiene y que se agudizará en los próximos años.

    Resumen

    El artículo consiste en una descripción comparada de dos edificios: Monticello ‐la casa que Thomas Jefferson construyó para sí mismo en Virginia‐ y Taliesin ‐la casa y estudio de Frank Lloyd Wright en Wisconsin‐. El texto estudia en primer lugar las fuentes arquitectónicas y la evolución del proyecto de Monticello, para centrarse después en la explicación de Taliesin. Hay una cierta similitud en el modo en que Monticello y las casas de  Wright ‐en concreto la Ward Willitts‐ se extienden  horizontalmente en el terreno y, volviendo a Taliesin, la tesis  principal del texto es que tanto la residencia de Jefferson como la de Wright se asientan sobre una colina, pero Monticello  ‘corona’ su cima, mientras que Taliesin la bordea, se sitúa como  una ‘ceja’ respecto a la misma. En definitiva, de este  último edificio se puede afirmar que es una ‘casa natural’, que  logra una plena integración entre arquitectura y naturaleza.

    Abstract

    This article consists of a comparative description of two buildings: Monticello, Thomas Jefferson’s residence which he  built for himself in Virginia, and Taliesin, the studio and home of Frank Lloyd Wright in Wisconsin. First, the text studies the  architectural references and evolution of the project for  Monticello, in order to later focus on explaining Taliesin. There is a certain similarity in the way that Monticello and Wright’s  houses (especially the Ward Willits House extend horizontally  across the land. The thesis of this article is that both Jefferson’s and Wright’s residences rest upon a hill, but Monticello crowns  the top while Taliesin borders it like an eyebrow. In conclusion, we can say that Taliesin is a “natural house”, which manages to fully integrate its architecture with nature

The chemical treatment by ammonia causes reduction in the proportion of the cell wall, in addition to providing non-protein nitrogen for the microbial protein synthesis in the rumen. Babassu palm hay ammoniated with 4% urea (BHAU4% was evaluated in this study as a substitute for guinea grass hay in the maintenance diets of goats in terms of intake, digestibility in vivo, and the partitioning of energy and nitrogen compounds. Twenty Anglo-Nubian male goats were used in a randomised block design with four treatments (diets containing 0, 33, 66, or 100% BHAU4% and five replicates (animals/block.

    Full Text Available Digital games are a commercial product developed and distributed by media companies and often uses characters or scenarios of movies, books, and comics. The digital game play comes from individual media consumption patterns. Playing digital games also offer experience and satisfaction based on interactive communication technologies and immersive gameplay. In this digital age, digital games became more social-based, which means they implement the need to invite friends on social media to come into play and help each other in the game. The problems of this study was to determine what factors make Hay Day popular among the players and to find out how Hay Day changing the social patterns interaction of the players. This study aims to look at the functions of digital games in the context of communication with relations in social media and why certain games can achieve very high popularity, while other games failed miserably. This research focuses on Hay Day. The method used is descriptive qualitative approach with case study method. Data collection is using interviews with players active in the game, as well as observation and literature studies. The results showed that a game may gain popularity if someone has a social media environment prior to play. Interactive concept, simulation, and fantasy game technology are also the reason Hay Day became very popular. The perception that the digital game player who formerly regarded as anti-social experience has shifted in the concept of digital game-based social bookmark. Players who have a lot of friends in games are seen as someone who has a lot of friends and a high social level. This is in line with the functions of a traditional game in Indonesian culture, where the region has a wide variety of games to be played together and motivate positive social interaction. Function of digital games also increased, other than playing the game as entertainment, but also now the game became one of the effective

    Hay-hole falls are a prevalent source of trauma among Anabaptists-particularly Anabaptist youth. We sought to decrease hay-hole falls in South Central Pennsylvania through the development and distribution of all-weather hay-hole covers to members of the at-risk Anabaptist community. Following the creation of a rural trauma prevention syndicate, hay-hole cover prototypes co-designed and endorsed by the Pennsylvania Amish Safety Committee were developed and distributed throughout South Central Pennsylvania. Preintervention and postintervention surveys were distributed to recipients to gain an understanding of the hay-hole fall problem in this population, to provide insight into the acceptance of the cover within the community, and to determine the efficacy of the cover in preventing falls. A total of 231 hay-hole covers were distributed throughout eight rural trauma-prone counties in Pennsylvania. According to preintervention survey data, 52% of cover recipients reported at least one hay-hole fall on their property, with 46% reporting multiple falls (median fall rate, 1.00 [1.00-2.00] hay-hole falls per respondent). The median self-reported distance from hay-hole to ground floor was 10.0 (8.00-12.0) feet, and the median number of hay-holes present on-property was 3.00 (2.00-4.00) per respondent. Postintervention survey data found 98% compliance with hay-hole cover installation and no subsequent reported hay-hole falls. With the support of the Pennsylvania Amish Safety Committee, we developed a well-received hay-hole cover which could effectively reduce fall trauma across other rural communities in the United States.

    Sporotrichosis is a subacute/chronic fungal infection caused by Sporothrix schenckii. The fungus thrives on organic matter including hay, wood, moss, soil and plants. Zoonotic transmission has also been reported. Lesions present as superficial skin nodules that become purulent and ulcerate. Lymphocutaneous spread is common. Haematogenous spread is uncommon and case fatality is rare. The aim of this article is to describe an outbreak of sporotrichosis in New South Wales. A cluster of six cases was identified in the NSW mid-north coast area in the first half of 2013. Telephone interviews were conducted in an attempt to identify possible exposures. General practitioners were contacted to report on patients with chronic non-healing skin lesions. A batch of mouldy hay supplied by a local farmer was identified as the potential source of exposure. Despite effective treatment with oral antifungals, diagnosis of sporotrichosis is often delayed and prolonged courses of antibiotics are unnecessarily prescribed. Timely detection and management (including referral to a dermatologist or infectious diseases specialist) significantly reduces morbidity. Personal protection is the key to prevention.

    2017-04-24

    The HayWired scenario is a hypothetical earthquake sequence that is being used to better understand hazards for the San Francisco Bay region during and after an earthquake of magnitude 7 on the Hayward Fault. The 2014 Working Group on California Earthquake Probabilities calculated that there is a 33-percent likelihood of a large (magnitude 6.7 or greater) earthquake occurring on the Hayward Fault within three decades. A large Hayward Fault earthquake will produce strong ground shaking, permanent displacement of the Earth’s surface, landslides, liquefaction (soils becoming liquid-like during shaking), and subsequent fault slip, known as afterslip, and earthquakes, known as aftershocks. The most recent large earthquake on the Hayward Fault occurred on October 21, 1868, and it ruptured the southern part of the fault. The 1868 magnitude-6.8 earthquake occurred when the San Francisco Bay region had far fewer people, buildings, and infrastructure (roads, communication lines, and utilities) than it does today, yet the strong ground shaking from the earthquake still caused significant building damage and loss of life. The next large Hayward Fault earthquake is anticipated to affect thousands of structures and disrupt the lives of millions of people. Earthquake risk in the San Francisco Bay region has been greatly reduced as a result of previous concerted efforts; for example, tens of billions of dollars of investment in strengthening infrastructure was motivated in large part by the 1989 magnitude 6.9 Loma Prieta earthquake. To build on efforts to reduce earthquake risk in the San Francisco Bay region, the HayWired earthquake scenario comprehensively examines the earthquake hazards to help provide the crucial scientific information that the San Francisco Bay region can use to prepare for the next large earthquake, The HayWired Earthquake Scenario—Earthquake Hazards volume describes the strong ground shaking modeled in the scenario and the hazardous movements of

    The HayWired Earthquake Scenario—Engineering Implications is the second volume of U.S. Geological Survey (USGS) Scientific Investigations Report 2017–5013, which describes the HayWired scenario, developed by USGS and its partners. The scenario is a hypothetical yet scientifically realistic earthquake sequence that is being used to better understand hazards for the San Francisco Bay region during and after a magnitude-7 earthquake (mainshock) on the Hayward Fault and its aftershocks.Analyses in this volume suggest that (1) 800 deaths and 16,000 nonfatal injuries result from shaking alone, plus property and direct business interruption losses of more than $82 billion from shaking, liquefaction, and landslides; (2) the building code is designed to protect lives, but even if all buildings in the region complied with current building codes, 0.4 percent could collapse, 5 percent could be unsafe to occupy, and 19 percent could have restricted use; (3) people expect, prefer, and would be willing to pay for greater resilience of buildings; (4) more than 22,000 people could require extrication from stalled elevators, and more than 2,400 people could require rescue from collapsed buildings; (5) the average east-bay resident could lose water service for 6 weeks, some for as long as 6 months; (6) older steel-frame high-rise office buildings and new reinforced-concrete residential buildings in downtown San Francisco and Oakland could be unusable for as long as 10 months; (7) about 450 large fires could result in a loss of residential and commercial building floor area equivalent to more than 52,000 single-family homes and cause property (building and content) losses approaching $30 billion; and (8) combining earthquake early warning (ShakeAlert) with “drop, cover, and hold on” actions could prevent as many as 1,500 nonfatal injuries out of 18,000 total estimated nonfatal injuries from shaking and liquefaction hazards.

    Many horse owners find round bales convenient, less labor intensive, and more affordable than other hay types, but report an inability to control horse BW gain and excessive hay waste. The objectives were to compare hay waste, hay intake, and payback of 9 round-bale feeders and a no-feeder control when used during horse feeding. Nine round-bale feeders were tested: Cinch Net, Cone, Covered Cradle, Hayhut, Hay Sleigh, Ring, Tombstone, Tombstone Saver, and Waste Less. Each feeder design was placed on the ground in a dirt paddock. Five groups of 5 horses were fed in rotation for a 4-d period with each feeder. Every fourth day, groups were rotated among paddocks and a new round bale was placed in each feeder. In the 5 paddocks used, 5 feeders were installed for d 1 through 20, and the remaining 4 feeders and no-feeder control were installed for d 21 through 40. Groups of horses were sequentially assigned to feeders using two 5 × 5 Latin squares, the first for d 1 through 20, the second for d 21 through 40. Horse groups of similar age, BW, breed, and sex were formed from 25 Quarter Horse and Thoroughbred geldings and open mares (means: 11 yr; 541 kg of BW). Hay on the ground surrounding the feeder was collected daily, dried, and weighed. The total amount of hay removed around each feeder for a 4-d period was considered waste. Dry matter intake was estimated as the difference between hay disappearance and waste. Number of months for the reduction in waste to repay feeder cost (payback) were calculated using hay valued at $110/t, and improved feeder efficiency over the control. Feeder design did not affect hay intake (P > 0.05); all feeders resulted in an estimated hay intake of 2.0 to 2.4% BW; the no-feeder control resulted in a reduced intake of 1.3% BW (P = 0.001). Mean percentage of hay waste differed among feeders (P feeder control, 57%. Feeder design also affected payback (P feeder design affected hay waste and payback, but not estimated hay intake or BW change

    Prairie hay meadows are important reservoirs of grassland biodiversity in the tallgrass prairie regions of the central United States and are the object of increasing attention for conservation and restoration. In addition, there is growing interest in the potential use of such low-input, high-diversity (LIHD) native grasslands for biofuel production. The uplands of eastern Kansas, USA, which prior to European settlement were dominated by tallgrass prairie, are currently utilized for intensive agriculture or exist in a state of abandonment from agriculture. The dominant grasslands in the region are currently high-input, low-diversity (HILD) hay fields seeded to introduced C3 hay grasses. We present results from a long-term experiment conducted in a recently abandoned HILD hay field in eastern Kansas to evaluate effects of fertilization, haying, and native species sowing on community dynamics, biomass, and potential for restoration to native LIHD hay meadow. Fertilized plots maintained dominance by introduced grasses, maintained low diversity, and were largely resistant to colonization throughout the study. Non-fertilized plots exhibited rapid successional turnover, increased diversity, and increased abundance of C4 grasses over time. Haying led to modest changes in species composition and lessened the negative impact of fertilization on diversity. In non-fertilized plots, sowing increased representation by native species and increased diversity, successional turnover, and biomass production. Our results support the shifting limitations hypothesis of community organization and highlight the importance of species pools and seed limitations in constraining successional turnover, community structure, and ecosystem productivity under conditions of low fertility. Our findings also indicate that several biological and functional aspects of LIHD hay meadows can be restored from abandoned HILD hay fields by ceasing fertilization and reintroducing native species through

    Animals with partial alopecia were seen frequently in a breeding colony of guinea pigs. No pathologic aetiology could be determined. An influence of nutrition on the density of the hair coat was considered. Breeding groups were fed one of the commercial guinea pig diets of differing composition, with or without the addition of hay. Observation occurred over a period of months and the quality of the hair coat was evaluated periodically using a semi-quantitative scoring system. More extensive and more frequent fur defects were found is guinea pigs receiving a breeding diet with a high content of crude protein (23%) and a low level of crude fibre (12%), offered hay only restrictively compared with animals receiving a diet with a lower content of crude protein (15.5%) and a higher level of crude fibre (19.5%), offered the same amount of hay. The amount of hay offered is of paramount importance. Animals fed only the diet with the higher level of crude fibre (19.5%), according to the manufacturer's instructions as a complete food, without the addition of hay, showed a less dense hair coat within 4 weeks. In our colony a group of five breeding animals and their young required 200 g of hay daily in order to improve their hair coat quality to normal. Conversely, animals receiving less hay had progressively deteriorating hair coat density. Not only the amount of hay offered, but also the accessibility for all animals plays a role in preventing alopecia in guinea pigs. In larger cages (twice the usual ground surface area) fur defects were seen when the same amount of hay (200 g) was offered in only one central area, rather than spread out evenly throughout the cage. Hair loss was observed to be the result of trichophagia between adult animals kept in the same cage. The need for crude fibre of breeding animals does not appear to be completely met by pellets rich in fibre segments.

    Full Text Available Objective The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. Methods Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration containing 60% (dry matter [DM] basis of basal starter feed and 40% (DM basis of forage, but varied in composition of forage source including i alfalfa (40% DM, AH; ii alfalfa hay (26.7% DM+oat hay (13.3% DM; OH; iii alfalfa hay (26.7% DM+corn silage (13.3% DM; WS. Results Dry matter intake was not different among treatment groups (p>0.05. However, BW (p<0.05 and average daily gain (p<0.05 of calves fed AH and OH were greater than WS-fed calves, whereas heart girth was greater in OH-fed calves than those fed AH and WS (p<0.05. Ruminal fermentation parameters including proportion of butyric acid, acetated-to-propionate ratio, concentration of total volatile fatty acid, protozoal protein, bacterial protein, and microbial protein in rumen were the highest in OH (p<0.05 and the lowest in WS. Compared with the AH and WS, feeding oat hay to postweaning calves increased crude protein digestibility (p<0.05, and decreased duration of diarrhea (p<0.05 and fecal index (p<0.05. Conclusion Our results suggested that partially replacing alfalfa hay with oat hay improved ruminal fermentation, nitrogen utilization, and reduced incidence of diarrhea in post-weaning dairy calves.

    Grasslands are often abandoned due to lack of profitability. Extensively cultivating grassland for utilization in a biogas-based biorefinery concept could mend this problem. Efficient bioconversion of this lignocellulosic biomass requires a pretreatment step. In this study the effect of different steam explosion conditions on hay digestibility have been investigated. Increasing severity in the pretreatment induced degradation of the hemicellulose, which at the same time led to the production of inhibitors and formation of pseudo-lignin. Enzymatic hydrolysis showed that the maximum glucose yields were obtained under pretreatment at 220 °C for 15 min, while higher xylose yields were obtained at 175 °C for 10 min. Pretreatment of hay by steam explosion enhanced 15.9% the methane yield in comparison to the untreated hay. Results indicate that hay can be effectively converted to methane after steam explosion pretreatment. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This final report provides technical information on the development of a near infrared reflectance spectroscopy (NIRS) system for the analysis of alfalfa hay. The purpose of the system is to provide consistent quality for processing alfalfa stems for fuel and alfalfa leaf meal products for livestock feed. Project tasks were to: (1) develop an NIRS driven analytical system for analysis of alfalfa hay and processed alfalfa products; (2) assist in hiring a qualified NIRS technician and recommend changes in testing equipment necessary to provide accurate analysis; (3) calibrate the NIRS instrument for accurate analyses; and (4) develop prototype equipment and sampling procedures as a first step towards development of a totally automated sampling system that would rapidly sample and record incoming feedstock and outbound product. An accurate hay testing program was developed, along with calibration equations for analyzing alfalfa hay and sun-cured alfalfa pellets. A preliminary leaf steam calibration protocol was also developed. 7 refs., 11 figs., 10 tabs.

    Full Text Available The objective of this work was to evaluate the performance of Holstein calves in suckling and post-weaning phases, intensively managed during suckling in the absence or presence of hay. Twenty-four male Holstein calves, at an average age of 15 days and initial weight of 43 kg were used in the experiment. The experimental design was completely randomized, consisting of two treatments and six replications. The treatments were as follows: 1 suckling with milk substitute + initial concentrate for calves, ad libitum + temperate grass hay (oat/ryegrass, ad libitum; 2 suckling with milk substitute + initial concentrate for calves, ad libitum. No significant difference was found between treatments for weight gain and feed conversion. However, the supply of hay caused an increase in daily dry matter intake (2.127 vs 1.894 kg. The intake of hay promoted greater stimulus to consumption of concentrate and greater weight at weaning.

    The natural diet of free-ranging horses is grass, which is typically high in fiber and calorically dilute, however diets for high performance domestic horses are often low in fiber and calorically dense. The aim of the study was to determine the motivation of horses for hay when fed a low roughage diet. Their motivation could be used to determine if low roughage diets compromise the welfare of horses. Eight mares were fed two different diets in counterbalanced order: ad libitum orchard grass hay; a complete pelleted feed (pellets). Each trial lasted three weeks, with a one-week transition period between diets. To determine the motivation of horses for fiber they were taught to press a panel to obtain a food reward. The fixed ratio (FR) was increased using a progressive ratio ((1,2,4,7,11…) technique. When fed pellets, the horses worked for a median FR of 1 (Range=1-497) to attain pellets, and when fed hay, they worked for a median FR of 25.5 (4-497) to attain pellets. When fed hay, the horses worked for a median FR of 0 (0-0) to attain hay, and when fed pellets, they worked for a FR of 13 (2-79) to attain hay. These results indicate a greater motivation for hay, a high fiber diet, when fed a low fiber diet. The horses spent 10 (5-19.4)% of their time during a 24-hour period eating pellets compared to 61.5 (29-76) % of their time eating hay. Horses spent 58% of their time standing when fed the pellets and only 37% of their time standing when fed hay. Searching behavior (i.e. sifting through wood shaving bedding for food particles) took up 11.5 (1.4-32) % of the horse's day when fed pellets, but only 1.2 (0-3.5) % of the daily time budget when fed hay. Horses chew more times when eating a hay diet (43,476chews/day) than when eating a pellet diet (10,036chews/day). Fecal pH was lower in horses fed the pelleted diet. Copyright © 2010 Elsevier Inc.

    Full Text Available Aplicações de artefatos de borracha muitas vezes requerem um conjunto de propriedades que não podem ser fornecidas por um único elastômero sendo, então necessário, que misturas de dois ou mais polímeros sejam empregadas. Nesses casos, os demais ingredientes que normalmente são adicionados, distribuem-se de modo diferente dependendo de sua afinidade com cada uma das borrachas. O grau de dispersão de cada um desses ingredientes em cada fase elastomérica irá influenciar a velocidade e o grau de vulcanização e, certamente, terá conseqüências sobre o desempenho do composto final. Neste trabalho, a borracha natural (NR foi misturada ao elastômero de butadieno-estireno (SBR na proporção de 1:1 em peso. As composições foram preparadas em misturador de cilindros, segundo a norma ASTM D 3182, empregando-se quatro maneiras distintas para a incorporação dos aditivos. Após a vulcanização foram estudadas propriedades mecânicas, como resistências à tração e ao rasgamento e dureza, propriedades termo-dinâmico-mecânicas e a morfologia de cada uma das composições. As propriedades mecânicas foram avaliadas de acordo com as normas ASTM específicas para cada ensaio. Os resultados mostram que, apesar de se usar a mesma formulação, o modo de preparo tem grande influência sobre as propriedades, o que é detectável pelas propriedades mecânicas e pela análise morfológica, e evidenciado através de testes sensíveis, como o dinâmico-mecânico. No caso da mistura NR/SBR as melhores propriedades são obtidas quando é favorecida a vulcanização da borracha que, isoladamente, apresenta propriedades inferiores.

Os indivíduos ordenavam 4 alternativas: automóvel, táxi, ônibus expresso existente e um trem expresso proposto, descritas pelos atributos de custo, tempo esperado de viagem e confiabilidade do tempo de viagem, expressa através de uma margem de segurança. Modelos de escolha discreta foram estimados, considerando os efeitos de painel, aninhamento e de inércia. Os resultados indicaram que viajantes a negócios e de alta renda são menos sensíveis ao custo da viagem de acesso ao aeroporto. A importância da confiabilidade do tempo de viagem é maior do que a atribuída ao tempo esperado de viagem e não foi afetada por variações sistemáticas.

    Palavras-chave: valor de confiabilidade; acesso terrestre a aeroportos; escolha de modo; modelo logit misto; preferência declarada.

    Abstract: The paper analyses systematic variation of tastes and preferences of air travelers regarding the choice of mode for the ground access to the São Paulo International Airport. A stated preference survey was conducted with individuals traveling to international destinations. Each respondent ranked 4 alternatives: auto, taxi, the existing express bus, and a proposed express train. Attributes describing modes were travel cost, average travel time and travel time reliability, expressed as a safety margin – the time period allocated by the individual for arriving at the airport at the preferred time. Discrete mode choice models were estimated, considering panel, nesting and inertia effects. Results indicated that business and higher income

    Full Text Available El presente estudio investiga la comprensión de niños acerca de la covariación de los términos de la división sin la presencia explicita del número. El objetivo es verificar si hay diferencia en el desempeño cuando se incluyen cantidades que son expresadas por números o por códigos relativos. Participaron 72 estudiantes pertenecientes a una escuela particular de Recife (Brasil, distribuidos en tres grupos: Prescolar (Infantil 3, primero y segundo año. Estos grupos resolvieron 12 problemas de división conside- rando dos condiciones: C1 (con la presencia explicita del número y C2 (con la presen- cia del código relativo. Los resultados revelan que los niños de 1º y 2º año presentan mejor desempeño cuando los problemas son presentados en la C2, a diferencia de los niños de prescolar (Infantil 3 que presentan mejor desempeño en la C1. Estos resul - tados apuntan a que el uso del código relativo parece ayudar a los niños en los años iniciales, principalmente a aquellos que están iniciando el aprendizaje de operaciones a pensar sobre las relaciones presentes en los enunciados de los problemas.

    Full Text Available Este artículo se propone analizar la representación de raza, clase y moral en los programas televisivos “Magaly TeVe” y “Al fondo hay sitio” desde una mirada antro-pológica de la televisión, comprendiendo sus dimensiones comunicativas, discursivas y sociales. Por un lado, al analizar el discurso de “Magaly TeVe” fue fácil constatar que el porqué y el cómo del éxito de la estrategia comunicativa de este fenómeno televisivo alu-dían estrechamente a códigos morales socialmente compartidos y a un modo configurado de organización, relación e interacción ya validados en nuestro tejido social. Por otro lado, al examinar el discurso de “Al fondo hay sitio” fue sencillo comprobar que hemos confundido, ingenuamente, inclusión con eventuales redenciones dentro de un marco de convergencia espacio-temporal de dos códigos culturales contradictorios y que perma-nentemente se relacionan e interactúan desde directrices de raza y clase que funcionan como núcleos semánticos que configuran, por un lado, la construcción narrativa y, por el otro, una determinada relación e interacción social de poder y violencia simbólica entre sus personajes.

  9. Bitumen on Water: Charred Hay as a PFD (Petroleum Flotation Device

    Full Text Available Global demand for petroleum keeps increasing while traditional supplies decline. One alternative to the use of conventional crude oils is the utilization of Canadian bitumen. Raw bitumen is a dense, viscous, semi-liquid that is diluted with lighter crude oil to permit its transport through pipelines to terminals where it can then be shipped to global markets. When spilled, it naturally weathers to its original form and becomes dense enough to sink in aquatic systems. This severely limits oil spill recovery and remediation options. Here we report on the application of charred hay as a method for modifying the surface behavior of bitumen in aquatic environments. Waste or surplus hay is abundant in North America. Its surface can easily be modified through charring and/or chemical treatment. We have characterized the modified and charred hay using solid-state NMR, contact angle measurements and infrared spectroscopy. Tests of these materials to treat spilled bitumen in model aquatic systems have been undertaken. Our results indicate that bitumen spills on water will retain their buoyancy for longer periods after treatment with charred hay, or charred hay coated with calcium oxide, improving recovery options.

    Full Text Available ABSTRACT The effect of treatment with xylanase and β-glucanase was evaluated for gas production and the ruminal degradation of nutrients from the hay of Tifton 85 grass and the stubble of maize, sorghum, peanut, sunflower and sesame crops. Two commercial fibrolytic enzymes were used (Dyadic xylanase PLUS - Xylanase; BrewZyme LP-β-glucanase, added to the hay at doses of 7.5 units of endoglucanase and 0.46 units of xylanase per 500 mg/gDM, for the cellulase and xylanase products respectively. The chemical composition of the hay was determined for no enzyme application and 24 hours after enzyme treatment, and the in vitro gas production and in situ microbial degradation was estimated for dry matter, organic matter, neutral detergent fibre and truly-degradable organic matter after 24 hours of incubation in the rumen. Enzyme treatment of the hay from Tifton 85 grass and the stubble of maize, sorghum, sunflower, peanut and sesame crops with the exogenous fibrolytic enzymes β-glucanase and xylanase influences in vitro gas production, and the in situ degradation of dry matter, organic matter, neutral detergent fibre and truly-degradable organic matter in the rumen. This variation can be attributed to differences in the chemical composition of the hay from the grass and the crop stubble, and to the different ways the enzymes act upon the cell wall.

    Full Text Available RESUMO A instalação de um grande empreendimento de mineração transformou a dinâmica social e ambiental na região próxima à Conceição do Mato Dentro, interior de Minas Gerais. A proposta extrativista alterou profundamente as relações históricas entre sujeitos, comunidades e territórios. A partir de uma pesquisa de orientação etnográfica analisamos como os jovens se subjetivam frente aos deslocamentos provocados na região. Os modos de subjetivação se constituem na configuração de formas de ser, sentir e agir frente às mudanças objetivas no território. Embora os jovens se queixem do empreendimento em razão dos problemas socioambientais causados, os mesmos reconhecem que a mineradora gerou o aumento de renda, a oferta de empregos e a promessa de desenvolvimento. Ao escutar as palavras dos jovens, vemos como eles são sujeitos que refletem e se posicionam frente aos conflitos em curso na região.

    Full Text Available Este artigo discute os modos de subjetivação femininos no mundo contemporâneo no contexto do trabalho e da família e problematiza o conceito de gênero tomando-o como relacional, plural, em uma tentativa de escapar à lógica binária. O artigo se baseia nos dados de uma pesquisa em que foram entrevistadas seis mulheres entre 25 e 35 anos de idade, de nível socioeconômico médio, cujas respostas foram submetidas à análise de conteúdo. Os resultados mostram mulheres que fazem parte de um contexto histórico que lhes endereça um discurso de sujeito autônomo e livre, que atribuem valor ao trabalho como profissão, mas que, ao mesmo tempo, são demandadas a atender as exigências de maridos e filhos no espaço privado. As múltiplas identidades que assumem requisitam posições de sujeito contraditórias, atravessadas pelas questões de gênero masculino/feminino que não mais dão conta de suas atuações no mundo. No entanto, simultaneamente, seus discursos indicam que as mulheres começam a buscar caminhos alternativos que as ajudem a superar essas relações dicotômicas.

    The objectives were to compare the effect of exogenous fibrolytic enzyme (Biocellulase A20) or anhydrous ammonia (4% DM) treatment on the nutritive value, voluntary intake, and digestion kinetics of bermudagrass (Cynodon dactylon cultivar Coastal) hay harvested after 2 maturities (5- and 13-wk regrowths). Six individually housed, ruminally cannulated Brangus steers (BW 325 ± 10 kg) were used in an experiment with a 6 × 6 Latin square design with a 3 (additives) × 2 (maturities) factorial arrangement of treatments. Each period consisted of 14 d of adaptation and 7, 4, 1, 1, and 4 d for measuring in vivo digestibility, in situ degradability, no measurements, rumen liquid fermentation and passage indices, and rate of solid passage, respectively. Steers were fed hay for ad libitum intake and supplemented with sugarcane molasses and distillers grain (supplement total of 2.88 kg DM/d). Enzyme did not affect the nutritional composition of hay but ammonia treatment decreased hay NDF, hemicellulose, and ADL concentrations and increased the CP concentration particularly for the mature lignified 13-wk hay. The enzyme increased NDF and hemicellulose digestibility of the 5-wk hay but decreased those of the 13-wk hay. Ammoniation decreased intake of hay but increased digestibility of DM, OM, NDF, hemicellulose, ADF, and cellulose and increased the ruminal in situ soluble and potentially digestible fractions and the rate of DM degradation of the 13-wk hay. Also, ammoniation increased the concentrations of ruminal NH3, total VFA, acetate, and butyrate but enzyme treatment did not. Neither enzyme addition nor ammoniation affected rate of liquid and solid passage. In conclusion, ammoniation decreased the concentration of most fiber fractions, decreased the intake of hays, and increased their CP concentration, in vivo digestibility, and in situ degradability at both maturities whereas enzyme application increased fiber digestibility of the 5-wk hay but decreased it in the case of

    The HayWired earthquake scenario, led by the U.S. Geological Survey (USGS), anticipates the impacts of a hypothetical magnitude-7.0 earthquake on the Hayward Fault. The fault is along the east side of California’s San Francisco Bay and is among the most active and dangerous in the United States, because it runs through a densely urbanized and interconnected region. One way to learn about a large earthquake without experiencing it is to conduct a scientifically realistic scenario. The USGS and its partners in the HayWired Coalition and the HayWired Campaign are working to energize residents and businesses to engage in ongoing and new efforts to prepare the region for such a future earthquake.

    Hay plays an important role in the natural production circle of human nutrition. The level of its pollution is an important factor which can effect various branches of the food industry. The aim of the reported exercise organized by the IAEA was to provide the participating laboratories an opportunity to check their analytical performance by comparing their results with the results of other laboratories and to establish the concentration level of trace elements for certification purposes. The hay powder was analyzed by 50 laboratories from 25 countries for 42 elements. Neutron activation, atomic absorption, atomic emission and X-ray spectroscopy were predominantly used as analytical methods. The results provided by the participants of the reported intercomparison exercise have enabled to certify the concentration of eighteen trace and minor elements and to establish non-certified information values for the concentration of an additional twelve elements in Hay Powder IAEA/V-10

    Full Text Available This study was conducted to evaluate the kinetics, physicochemical characteristics and particle size of digesta in the right ventral colon (RVC of horses fed coastcross hay ground to different degrees. Four horses fitted with cannulae in the RVC were used and were fed the following forms of hay: long, chopped, ground to 5 mm and ground to 3 mm. A Latin Square 4x4 study design was used. Each experimental period included 10 days for diet adaptation, four days for feces collection and one day for digesta collection. The kinetics of the particulate and solute phases of digesta were evaluated based on the mean retention time (MRT, passage rate (k and transit time (TT using two external markers: Cr-NDF and Co-EDTA. The TT of solid phase digesta was 3 hours longer (P0.05 in k or MRT in either the liquid or solid phase of digesta as a function of the different degrees of hay grinding. However, the liquid phase of digesta presented a higher k than the solid phase, with values of 3.28 and 2.73 h-1 being obtained, respectively. The smallest particle size and the lowest neutral detergent fiber contents in colon digesta were observed when hay ground to 3 mm was offered, leading to values of 0.51 mm and 53.46%, respectively. Grinding the hay increased the transit time of the liquid phase in the digestive tract of the horses, whereas no change in the kinetics of the solid phase digesta was observed. The grinding of hay reduced the NDF and the average particle size in the right ventral colon.

    Exposure to farming environments and siblings is associated with reduced risks of childhood hay fever and atopy. We explored the independence and interaction of these protective effects in the GABRIELA study. Questionnaire surveys on farming, asthma, and allergies were conducted in four central European areas among 79,888 6-12-yr-old children. Aeroallergen-specific serum IgE was measured in a stratified sample of 8,023 children. Multiple logistic regression was used to compare gradients in allergy prevalence by sibship size across three categories of exposure to farming environments. The prevalence of hay fever ranged from 2% (95% confidence interval 1.6%; 2.7%) among farmers' children with more than two siblings to 12% (11.2%; 13.0%) among children with no farm exposure and no siblings. Farming families were larger on average. More siblings and exposure to farming environments independently conferred protection from hay fever and atopy. There was no substantial effect modification between family size and exposure to farming environments. The odds ratios for hay fever per additional sibling were 0.79 among unexposed non-farm children, 0.77 among farm-exposed non-farm children, and 0.72 among children from farming families (2df interaction test: p = 0.41). The inverse association of exposure to farming environments with hay fever is found in all sizes of family, with no substantial tendency to saturation or synergism. This suggests that different biological mechanisms may underlie these two protective factors. Combinations of a large family and exposure to farming environments markedly reduce the prevalence of hay fever and indicate the strength of its environmental determinants. © 2013 John Wiley & Sons A/S.

    The objective of the present experiment was to determine if carcass quality and fatty acid profiles of longissimus thoracis (LT) and hamburger would be affected by feeding steers extruded flaxseed on its own followed by hay (non-TMR) compared to when hay and extruded flaxseed were fed together (TMR). Forty-eight steers in six pens were assigned to TMR or non-TMR for an average of 242days. Dry matter intake was lower for non-TMR versus TMR steers (10.56 vs. 11.42kg/d; P=0.02), but final live weight (610±0.50kg) and average daily gain (1.18±0.02kg/d) did not differ. Compared to TMR, feeding non-TMR enriched LT and hamburger with α-linolenic acid (ALA; 18:3n-3) by 14%, vaccenic acid (VA; t11-18:1) by 44%, rumenic acid (RA; c9,t11-18:2) by 40%, and conjugated linolenic acid (CLnA) by 58%. Overall, feeding extruded flaxseed separately from hay in a non-TMR was more effective at enhancing deposition of ALA, VA, RA and CLnA in beef. Crown Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available The huge amount of coffee pulp waste is an environmental problem. Anaerobic fermentation is one of the alternative solutions. However, availability of coffee pulp does not appear for year-round, whereas biogas needs continuous feedstocks for digester stability. This research uses coffee pulp from Arabica Coffee Factory at Mengani, Kintamani, Bali–Indonesia. The coffee pulp was transformed into coffee pulp-hay product by sun drying for preservations to extend the raw materials through the year. Characterization of coffee pulp-hay was conducted after to keep for 15 mo for review the prospect as biogas feedstocks. Several parameters were analyzed such as C/N ratio, volatile solids, carbohydrate, protein, fat, lignocellulose content, macro-micro nutrients, and density. The review results indicated that coffee pulp-hay is prospective raw material for biogas feedstock. This well-proven preservation technology was able to fulfill the continuous supply. Furthermore, some problems were found in the recent preliminary experiment related to the density and fungi growth in the conventional laboratory digester. Further investigation was needed to implement the coffee pulp – hay as biogas feedstocks.

    A study was carried to determine the nutrients and their digestibility in Acacia seyal and Balanities aegyptiaca legume browses and compared with Chloris gayana hay. Samples were taken from these two leguminous forages at Mogotio and Emining divisions of Koibatek district and fed to sheep in a change over design. The sheep were housed in individual pens and fitted with faecal collection bags. They were fed and faeces collected twice daily. An adaptation period of 14 days, Faecal collection of 7 days and changeover of 10 days were enforced. Nutrients analysed for during digestibility included DM, OM, CP, NDF, Hemicellulose and Cellulose. The nutrients compositions were 651, 916, 112, 370, 339, 59 and 84; 665, 920, 152, 443, 341, 89 and 80, 845, 924, 68, 730, 463, 57, and 76 for DM, OM, CP, NDF, ADF, and ash in Acacia seal, Balanities aegyptiaca and Chloris gayana hay. The in vivio digestibility results were different (p<0.05) for all nutrients.

    Inclusion of forage and its physical form in starter may affect rumen development, average daily gain (ADG), and dry matter intake (DMI) of dairy calves. To evaluate the effects of forage and its physical form (chopped vs. pelleted) on growth of calves under a high milk feeding regimen, 32 Holstein calves (38.8±1.1kg) were assigned at birth to 1 of 3 treatments in a completely randomized block design. Dietary treatments (% of dry matter) were (1) 100% semi-texturized starter (CON); (2) 90% semi-texturized starter + 10% chopped alfalfa hay (mean particle size=5.4mm) as a total mixed ration (TMR; CH); and (3) 90% semi-texturized starter + 10% pelleted alfalfa (mean=5.8mm) hay as a TMR (PH). Data were subjected to mixed model analysis with contrasts used to evaluate effect of forage inclusion. Calves were weaned at 76 d of age and the experiment finished 2 wk after weaning. Individual milk and solid feed consumption were recorded daily. Solid feed consumption and ADG increased as age increased (effect of week), but neither forage inclusion nor physical form of forage affected these variables pre- or postweaning. Plasma urea N was affected by treatments such that the CON group had a lower concentration than forage-fed groups. Forage inclusion, but not physical form, resulted in increased total protein in plasma. Although days with elevated rectal temperature, fecal score, and general appearance were not affected by dietary treatments, calves fed alfalfa hay during the first month of life had fewer days with respiratory issues, regardless of physical form of hay. We concluded that provision of forage does have some beneficial effects in calves fed large amounts of milk replacer, but pelleted alfalfa hay did not result in any improvement in calf performance or health.

    1985-05-01

    Full Text Available In order to increase the fodder available for roedeer during wintertime, late harvested hay was placed on racks early in November in three consecutive years. Freeezing kept the hay dry and fresh during all three winters. In the first winter, with much snow, the bulk of the hay was consumed whereas consumption in the two subsequent mild winters was low and selective. The crude protein content of the hay was low (3.5 - 8.4% dry matter. Metabolizable energy estimated from digestion in vitro was 3.5 — 5.6 MJ per kg dry matter. Rumen liquor from roe deer during a mild winter gave lower in vitro digestion than liquor from sheep fed with ordinary rations. The value of this poor hay for roe deer is discussed with respect to the animals requirements, seasonal adaption, the energy and protein content of the hay, water consumption and normal behavior. The results indicate that late harvested hay may be more suitable than regularly harvested hay or concentrates to help roe deer to survive spells of severe winter conditions. With late harvested hay placed out at several localized feeding sites, the risks of indigestion and dehydration, associated with a more concentrated, feed, are minimized and the ranking among the roe deer in particular will be less important and thus more animals will have improved prospects of gaining access to the fodder.Tilskottsutfodring av rådjur (Capreolus capreolus L med sent skordat ho.

Portanto, é importante definir qual o melhor modo de aplicação e fonte de B para o bom desenvolvimento do eucalipto. Assim, o objetivo deste trabalho foi comparar o efeito de fontes de B com alta e baixa solubilidade na cultura do eucalipto, bem como a aplicação foliar do micronutriente. O experimento foi conduzido em uma área com latitude 20o 34’ S e longitude 51o 50’ O e altitude de 305 m, no período de 01/2012 a 02/2014. O delineamento experimental foi o de blocos casualizados com seis tratamentos e cinco repetições, dispostos em um esquema fatorial de 3 x 2, sendo: 0 kg ha-1 de B, 1 kg ha-1 de B utilizando como fonte o ácido bórico (alta solubilidade, 17% B ou1 kg ha-1 de B utilizando como fonte o borogran (baixa solubilidade, 10% B, aplicados no sulco de plantio, com ou sem aplicações de ácido bórico via foliar na dose de 0,5% de ácido bórico na calda com volume de 250 L ha-1. Com a omissão de B via foliar houve incremento em altura de plantas nos tratamentos que receberam a aplicação do micronutriente no plantio, diferindo significativamente da testemunha. Porém, ambas as fontes, independente da solubilidade, apresentaram resultados semelhantes. As duas aplicações de B via foliar foram suficientes para que houvesse incremento em altura de plantas, quando comparadas aos tratamentos que não receberam aplicação de B no plantio, aos 21 meses. Aos 24 meses após o plantio foi constatado aumento no teor foliar de B nos tratamentos que receberam aplicação foliar. No entanto, esta não incrementou o crescimento, DAP e volume de madeira do clone de eucalipto. A aplicação de B no plantio, independente da fonte utilizada, assim como aplicação foliar do elemento, foram suficientes para reduzir os sintomas de deficiência de B.

    Research to date has suggested that access to forage before weaning can limit rumen development in calves, but no research has yet addressed the role of forage for calves fed higher quantities of milk. This study compared performance and rumen development of calves provided high volumes (equivalent to approximately 20% of calf birth weight) of milk with and without access to hay. At d 3 of age, individually housed calves were randomly assigned to treatment (either ad libitum access to chopped grass hay or no forage; n=15 calves per treatment, 10 heifers, and 5 bulls). All calves were provided ad libitum access to water and starter throughout the study. All calves were offered 8L of milk/d from a nipple bottle from d 3 to 35, 4 L/d from d 36 to 53, and 2L/d until weaning at d 56. Solid feed intake and growth parameters were monitored from d 3 to 70. At d 70, males from both treatments were slaughtered to measure rumen development parameters. Overall dry matter (DM) intake from solid feed did not differ between treatments before wk 5. However, during wk 6 to 10, calves fed forage consumed more total DM (starter plus hay) than did calves fed no forage. Hip and wither height, heart girth, and body barrel at d 3, 56, and 70 did not differ between treatments. Reticulorumen weight was heavier in calves fed hay versus those fed only starter (12.77±1.29 vs. 7.99±0.69 kg with digesta; 1.89±0.05 vs.1.60±0.09 kg without digesta). Body weight without digesta was similar in calves fed forage or no forage. Mean rumen pH was higher in calves fed hay compared with those fed no forage (5.49±0.08 vs. 5.06±0.04). In conclusion, provision of chopped hay to calves fed high volumes of milk can promote solid feed DM intake and rumen development without affecting BW gain.

    Alfalfa-brome hay, haylage, .5% urea-treated corn silage, or .5% urea plus 1% dried whey-treated corn silage was fed as the only forage to one of four groups of 10 lactating cows per group for a lactation trial of 10 wk. Rumen samples were collected via stomach tube 3 to 4 h after the morning feeding. The pH of the rumen samples from cows fed hay was higher than for cows fed haylage, urea-treated corn silage, and urea-whey corn silage, 6.69 versus 6.36, 6.40, and 6.50. Total volatile fatty acids and propionate were highest from cows fed urea-whey corn silage and were higher on all three fermented forages than cows fed hay. Acetate/propionate ratio was highest from cows fed hay and lowest from cows fed corn silages. Butyrate was highest from cows fed haylage or hay. Milk protein composition was not affected by ration although nonprotein nitrogen of milk was highest from cows fed the urea-treated corn silages. Oleic acid and total unsaturated fatty acids were lowest in milk fat from cows fed hay while palmitic acid was highest from cows fed hay and haylage. These results suggest that type of forage fed may cause small changes in rumen fermentation and in milk composition. The importance of these changes is unknown but may affect properties of dairy products produced from this milk.

  4. Towards a political ontology of state power: a comment on Colin Hay's article.

    Jessop, Bob

    2014-09-01

    This article offers some critical realist, strategic-relational comments on Colin Hay's proposal to treat the state as an 'as-if-real' concept. The critique first develops an alternative account of ontology, which is more suited to analyses of the state and state power; it then distinguishes the 'intransitive' properties of the real world as an object of investigation from the 'transitive' features of its scientific investigation and thereby provides a clearer understanding of what is at stake in 'as-if-realism'; and it ends with the suggestion that a concern with the modalities of state power rather than with the state per se offers a more fruitful approach to the genuine issues raised in Hay's article and in his earlier strategic-relational contributions to political analysis. © London School of Economics and Political Science 2014.

    Both quantity and quality of forages are important in dry season feeding. Eight Thai native beef bulls were arranged in a Completely randomized design to evaluate dwarf Napier namely Sweet grass (Pennisetum purpureum cv. Mahasarakham) preserved as silage or hay on feed intake, digestibility, and rumen fermentation. The animals were fed with forage ad libitum supplemented with concentrate mixture at 1.0% of BW for 21 days; data were collected during the last 7 days. The results showed that there were differences (P  0.05) in animals fed silage and hay. Sweet grass is better preserved as hay rather than silage.

    Willet M. Hays was a great benefactor to plant breeding and the founder of the American Genetic Association (AGA). We commemorate the AGA's centennial. We mined university archives, U.S. Department of Agriculture (USDA) yearbooks, plant breeding textbooks, scientific periodicals, and descendants for information. Willet Hays first recognized the individual plant as the unit of selection and started systematic pure-line selection and progeny tests in 1888. He developed useful plant breeding methods. He selected superior flax (Linum usitatissimum L.), wheat (Triticum vulgare L.), corn (Zea mays L.), barley (Hordeum vulgare L.), and oat (Avena sativa L.) varieties, and discovered Grimm alfalfa (Medicago sativa L.); all became commercially important. He initiated branch stations for better performance testing. Willet Hays befriended colleagues in other universities, in federal stations, in a London conference, and in Europe. He gathered and spread the scientific plant breeding gospel. He also improved rural roads and initiated animal breeding records and agricultural economics records. He started the AGA in 1903, serving as secretary for 10 years. He became assistant secretary of agriculture in 1904. He introduced the project system for agricultural research. He authored or coauthored the Nelson Amendment, the Smith-Lever Act, the Smith-Hughes Act, and the protocol leading to the United Nations Food and Agriculture Organization-all involved teaching agricultural practices that improved the world.

    Full Text Available An inventory of 162 hay samples from Austrian permanent grasslands was used to obtain information about the precision of the in vitro NDF degradability (NDFd measured by the Daisy fermenter and its accuracy to predict in situ NDFd. The within forage standard error of the in vitro NDFd triplicate, obtained in five consecutive incubations, was equal to 2.8%, while the effect of the four jar positions in the fermenter was not significant. The cutting frequency had a great impact on the in situ effective NDFd of hays, which ranged (P<0.01 from values of 32.9, 43.1 and 48.3% in hays obtained from 2, 3 and 4 cuts/season, respectively. The regression analysis between the in vitro and in situ NDFd values (measured at 48h and effective, k=3%/h allowed to obtain medium degrees of correlation (r2 = 0.69 – 0.71; P<0.01 and low levels of accuracy (RSE = 4.0 -4.6 %.

    Full Text Available Resumen: Los sistemas con conmutación de modos se definen como aquéllos que pueden exhibir diferente comportamiento dinámico en función del estado en que se encuentran. Pueden por tanto ser descritos por un conjunto finito de subsistemas dinámicos y una lógica que rige la conmutación entre ellos. Una alternativa para su control es la arquitectura multi-controlador con supervisión ya que permite utilizar controladores de modo diferentes y alcanzar así múltiples objetivos de control. Pero la conmutación de controladores suele tener como consecuencia la aparición de saltos o transitorios derivados que pueden ser inaceptables. Este tipo de sistemas y problemática son frecuentes en diferentes áreas de aplicación industrial, en donde la tecnología de control más utilizada es el Controlador Lógico Programable (PLC. Es por ello que el objetivo de este trabajo es presentar un método de diseño e implementación de un mecanismo de transferencia sin salto (BT en una arquitectura multi-modo y multi-bucle para sistemas con conmutación de modos, en PLC y en conformidad con el estándar IEC 61131-3. La estrategia BT se basa en que controladores de modos candidatos a conmutar realicen un seguimiento a los controladores activos, siendo la detección del estado de operación actual y de los posibles estados siguientes, clave en la definición de la forma de ejecución de los algoritmos de control que componen la arquitectura. Se presentan también los pasos del diseño de la arquitectura completa así como resultados experimentales que validan la arquitectura. Abstract: Switched mode systems are defined as those represented by a finite set of linear subsystems and a set of logic rules orchestrating the switching among them. A set of dynamic subsystems together with a logical system that orchestrates the switching among them could be used in order to describe it. An alternative to control them is a supervisory multi-mode controller architecture

    The objective of this experiment was to investigate the effects of different levels of alfalfa hay (AH) and sodium propionate (Pro) added to starter diets of Holstein calves on growth performance, rumen fermentation characteristics, and rumen development. Forty-two male Holstein calves (40±2kg of birth weight) were used in a complete randomized design with a 3×2 factorial arrangement of treatments. Dietary treatments were as follows: (1) control = concentrate only; (2) Pro = concentrate with 5% sodium propionate [dry matter (DM) basis]; (3) 5% AH = concentrate + 5% alfalfa hay (DM basis); (4) 5% AH + Pro = concentrate + 5% alfalfa hay + 5% sodium propionate (DM basis); (5) 10% AH = concentrate + 10% alfalfa hay (DM basis); and (6) 10% AH + Pro = concentrate + 10% alfalfa hay + 5% sodium propionate (DM basis). All calves were housed in individual pens bedded with sawdust until 10wk of age. They were given ad libitum access to water and starter throughout the experiment and were fed 2L of milk twice daily. Dry matter intake was recorded daily and body weight weekly. Calves from the control, 10% AH, and 10% AH + Pro treatments were euthanized after wk 10, and rumen wall samples were collected. Feeding of forage was found to increase overall dry matter intake, average daily gain, and final weight; supplementing sodium propionate had no effect on these parameters. Calves consuming forage had lower feed efficiency than those on the Pro diet. Rumen fluid in calves consuming forage had higher pH and greater concentrations of total volatile fatty acids and molar acetate. Morphometric parameters of the rumen wall substantiated the effect of AH supplementation, as plaque formation decreased macroscopically. Overall, the interaction between forage and sodium propionate did not affect calf performance parameters measured at the end of the experiment. Furthermore, inclusion of AH in starter diets positively enhanced the growth performance of male Holstein calves and influenced

    This document reprints the communication given by F. Billiard, head of the international institute of refrigeration (IIF), at the COP-6 conference of La Haye (November 2000). In his talk, F. Billiard explains the contribution of the refrigeration industry to the global warming which is mainly due to the leaks of refrigerants (CFC, HCFC, HFC) and to the carbon dioxide emissions corresponding to the electric power consumption of refrigerating machineries, air-conditioners and heat pumps. Thus, the abatement of these greenhouse gas emissions requires an improvement of the confinement of the refrigeration equipments and a continuous optimization of their energy efficiency. A second part analyzes the key points of this communication and the choice of some objective appreciation criteria for the remedial actions to be implemented. A glossary completes the document.

    To date, no genome-wide association study (GWAS) has considered the combined phenotype of asthma with hay fever. Previous analyses of family data from the Tasmanian Longitudinal Health Study provide evidence that this phenotype has a stronger genetic cause than asthma without hay fever. We sought to perform a GWAS of asthma with hay fever to identify variants associated with having both diseases. We performed a meta-analysis of GWASs comparing persons with both physician-diagnosed asthma and hay fever (n = 6,685) with persons with neither disease (n = 14,091). At genome-wide significance, we identified 11 independent variants associated with the risk of having asthma with hay fever, including 2 associations reaching this level of significance with allergic disease for the first time: ZBTB10 (rs7009110; odds ratio [OR], 1.14; P = 4 × 10(-9)) and CLEC16A (rs62026376; OR, 1.17; P = 1 × 10(-8)). The rs62026376:C allele associated with increased asthma with hay fever risk has been found to be associated also with decreased expression of the nearby DEXI gene in monocytes. The 11 variants were associated with the risk of asthma and hay fever separately, but the estimated associations with the individual phenotypes were weaker than with the combined asthma with hay fever phenotype. A variant near LRRC32 was a stronger risk factor for hay fever than for asthma, whereas the reverse was observed for variants in/near GSDMA and TSLP. Single nucleotide polymorphisms with suggestive evidence for association with asthma with hay fever risk included rs41295115 near IL2RA (OR, 1.28; P = 5 × 10(-7)) and rs76043829 in TNS1 (OR, 1.23; P = 2 × 10(-6)). By focusing on the combined phenotype of asthma with hay fever, variants associated with the risk of allergic disease can be identified with greater efficiency.

    Full Text Available Five different hays were used to determine the effect of 5 different soaking and steaming treatments on the water soluble carbohydrate and microbial (bacteria and mould contents of UK hay. Hays were subjected to the following 5 treatments: 1. Dry; 2. Steamed for 50 minutes in the Haygain- 600 steamer; 3. Soaked in water at 16°C for 9 hours; 4. Steamed then soaked and 5. Soaked then steamed. Post treatment hays were tested for water soluble carbohydrates, bacteria and mould contents. Differences between means were determined using ANOVA and least significant difference with hay (5, bale (3 and treatment (5 as fixed factors, thus n = 75. Protein and ash proportions were unaltered in any of the treatments. Soaked, steamed then soaked and soaked then steamed treatments were all equally effective at reducing water soluble carbohydrates, with significantly (P<0.05 lower mean contents (79-83 g/kg DM compared with 126 and 122 g/kg dry matter (DM for dry and steamed respectively. Steamed and soaked then steamed had significantly (P<0.05 less bacteria (1.04×103 and 4.9×102 CFU/g DM compared with soaked which increased CFU/g DM from 6.0×104 in dry hay up to 3.5×105. Mould contents CFU/g DM were significantly (P<0.05 reduced by steaming (2 and soaking then steaming (1.9 but no difference was seen between dry (1148, soaked (692 or steamed then soaked (501. Soaking for 9 hours followed by steaming for 50 minutes in the Haygain steamer was the most effective method for reducing water soluble carbohydrates and microbial contamination in hay. Soaking or steaming+soaking lowered water soluble carbohydrates but significantly reduced the hygienic quality of the hay which could potentially compromise the health of the horse.

Se tomó como estudio de caso el subprograma local "Apoyo a Proyectos de Inversión Rural" (PAPIR de Desarrollo Rural de la Alianza Contigo. Se trabajó con un enfoque participativo con investigadores y personas beneficiarias del programa en el año 2004 en Villa Victoria, Estado de México. Se emplearon métodos de carácter cuantitativo y cualitativo considerando como enfoque a los modos de vida sustentables con el fin de interpretar los resultados desde un punto de vista amplio. Se concluyó que no existe suficiente evidencia para comprobar la operatividad funcional de las normas de operación oficiales, existe una tendencia del fomento al desarrollo rural mediante un enfoque territorial con una visión productiva. Los resultados denotan la presencia de indicadores sociales, económicos y ambientales consolidados y otros que interactúan entre sí, que no han sido considerados por la burocracia al determinar cómo evaluar el impacto del PAPIR. Se encontró que el tipo de apoyos otorgados no genera cambio alguno en el bienestar económico ni en el modo de vida de los beneficiarios.

    The quality of hay can directly affect the price of hay and also livestock productivity. Many kinds of methods have been developed for detecting the quality of hay and the method of near infrared spectroscopy (NIRS) has been widely used with consideration of its fast, effective and nondestructive characteristics during detecting process. In the present paper, the feasibility and effectiveness of application of NIRS to detecting hay quality were expounded. Meanwhile, the advance in the study of using NIRS to detect chemical compositions, extent of incursion by epiphyte, amount of toxicant excreted by endogenetic epiphyte and some minim components that can not be detected by using chemical methods were also introduced detailedly. Based on the review of the progresses in using NIRS to detect the quality of hay, it can be concluded that using NIRS to detect hay quality can avoid the disadvantages of time wasting, complication and high cost when using traditional chemical method. And for better utilization of NIRS in practice, some more studies still need to be implemented to further perfect and improve the utilization of NIRS for detecting forage quality, and more accurate modes and systematic analysis software need to be established in times to come.

    Selenium (Se) is an essential trace mineral important for immune function and overall health of cattle. The nasopharyngeal microbiota in cattle plays an important role in overall respiratory health, especially when stresses associated with weaning, transport, and adaptation to a feedlot affect the normal respiratory defenses. Recent evidence suggests that cattle diagnosed with bovine respiratory disease complex have significantly less bacterial diversity. The objective of this study was to determine whether feeding weaned beef calves Se-enriched alfalfa (Medicago sativa) hay for 9 weeks in a preconditioning program prior to entering the feedlot alters nasal microbiota. Recently weaned beef calves (n = 45) were blocked by sex and body weight, randomly assigned to 3 treatment groups with 3 pens of 5 calves per treatment group, and fed an alfalfa hay based diet for 9 weeks. Alfalfa hay was harvested from fields fertilized with sodium selenate at a rate of 0, 45.0 or 89.9 g Se/ha. Blood samples were collected biweekly and analyzed for whole-blood Se concentrations. Nasal swabs were collected during week 9 from one or two calves from each pen (total n = 16). Calculated Se intake from dietary sources was 3.0, 15.6, and 32.2 mg Se/head/day for calves consuming alfalfa hay with Se concentrations of 0.34 to 2.42 and 5.17 mg Se/kg dry matter, respectively. Whole-blood Se concentrations after 8 weeks of feeding Se-fertilized alfalfa hay were dependent upon Se-application rates (0, 45.0, or 89.9 g Se/ha) and were 155, 345, and 504 ng/mL (PLinear calves fed selenium-biofortified alfalfa hay compared with control calves showed that Se-supplementation tended to be associated with an enriched nasal microbiota. ANOSIM of unweighted UniFrac distances showed that calves fed high Se-biofortified alfalfa hay clustered separately when compared with control calves in the PCoA plot (R = 0.216, P = 0.04). The bacterial orders Lactobacillales and Flavobacteriales were increased in healthy

    Full Text Available Selenium (Se is an essential micronutrient in cattle, and Se-deficiency can affect morbidity and mortality. Calves may have greater Se requirements during periods of stress, such as during the transitional period between weaning and movement to a feedlot. Previously, we showed that feeding Se-fertilized forage increases whole-blood (WB Se concentrations in mature beef cows. Our current objective was to test whether feeding Se-fertilized forage increases WB-Se concentrations and performance in weaned beef calves. Recently weaned beef calves (n = 60 were blocked by body weight, randomly assigned to 4 groups, and fed an alfalfa hay based diet for 7 wk, which was harvested from fields fertilized with sodium-selenate at a rate of 0, 22.5, 45.0, or 89.9 g Se/ha. Blood samples were collected weekly and analyzed for WB-Se concentrations. Body weight and health status of calves were monitored during the 7-wk feeding trial. Increasing application rates of Se fertilizer resulted in increased alfalfa hay Se content for that cutting of alfalfa (0.07, 0.95, 1.55, 3.26 mg Se/kg dry matter for Se application rates of 0, 22.5, 45.0, or 89.9 g Se/ha, respectively. Feeding Se-fertilized alfalfa hay during the 7-wk preconditioning period increased WB-Se concentrations (P Linear<0.001 and body weights (P Linear = 0.002 depending upon the Se-application rate. Based upon our results we suggest that soil-Se fertilization is a potential management tool to improve Se-status and performance in weaned calves in areas with low soil-Se concentrations.

    This study aimed to examine the association of eczema, asthma and hay fever with mental health in a general child population and to assess the influence of parental socioeconomic position on these associations. We conducted a cross-sectional health survey of children aged 3, 6, 11 and 15 years in the City of Copenhagen, Denmark. Individual questionnaire data on eczema, asthma, and hay fever and mental health problems assessed using the Strengths and Difficulties Questionnaire (SDQ) was linked to register data on demographics and parental socioeconomic position. 9215 (47.9%) children were included in the analyses. Linear regression analyses showed that children with current eczema symptoms had higher SDQ scores (mean difference, 95% CI) of emotional problems (0.26, 0.12 to 0.39), conduct problems (0.19, 0.09 to 0.29) and hyperactivity problems (0.32, 0.16 to 0.48); children with current asthma symptoms had higher SDQ scores of emotional problems (0.45, 0.32 to 0.58), conduct problems (0.28, 0.18 to 0.38) and hyperactivity problems (0.52, 0.35 to 0.69); and children with current hay fever symptoms had higher SDQ scores of emotional problems (0.57, 0.42 to 0.72), conduct problems (0.22, 0.11 to 0.33), hyperactivity problems (0.44, 0.26 to 0.61) and peer problems (0.14, 0.01 to 0.26), compared with children without current symptoms of the relevant disease. For most associations, parental socioeconomic position did not modify the effect. Children with eczema, asthma or hay fever had more emotional, conduct and hyperactivity problems, but not peer problems, compared with children without these diseases. Atopic diseases added equally to the burden of mental health problems independent of socioeconomic position. Published by the BMJ Publishing Group Limited.

  17. The HayWired Scenario - How Can the San Francisco Bay Region Bounce Back Better?

    The HayWired scenario is a hypothetical yet scientifically realistic and quantitative depiction of a moment magnitude (Mw) 7.0 earthquake occurring on April 18, 2018, at 4:18 p.m. on the Hayward Fault in the east bay part of the San Francisco Bay area, California. The hypothetical earthquake has its epicenter in Oakland, and strong ground shaking from the scenario causes a wide range of severe impacts throughout the greater bay region. In the scenario, the Hayward Fault is ruptured along its length for 83 kilometers (about 52 miles). Building on a decades-long series of efforts to reduce earthquake risk in the SF Bay area, the hypothetical HayWired earthquake is used to examine the well-known earthquake hazard of the Hayward Fault, with a focus on newly emerging vulnerabilities. After a major earthquake disaster, reestablishing water services and food-supply chains are, of course, top priorities. However, problems associated with telecommunication outages or "network congestion" will increase and become more urgent as the bay region deepens its reliance on the "Internet of Things." Communications at all levels are crucial during incident response following an earthquake. Damage to critical facilities (such as power plants) from earthquake shaking and to electrical and telecommunications wires and fiber-optic cables that are severed where they cross a fault rupture can trigger cascading Internet and telecommunications outages, and restoring these services is crucially important for emergency-response coordination. Without good communications, emergency-response efficiency is reduced, and as a result, life-saving response functions can be compromised. For these reasons, the name HayWired was chosen for this scenario to emphasize the need to examine our interconnectedness and reliance on telecommunications and other lifelines (such as water and electricity). Earthquake risk in the SF Bay area has been greatly reduced as a result of previous concerted efforts; for

    Hay samples from 29 horse farms in Southern Upper Bavaria and 31 horse farms in Switzerland were taken and analysed for minerals such as calcium, magnesium, phosphorus and potassium. The content of herbs and legumes in the hay was determined and the Weende analysis was performed. Comparison between Bavaria and Switzerland resulted in comparable calcium contents of approximately 4 g Ca/kg dry matter (DM) in grass hay. Hay with more than 10% of herbs and legumes found only in Switzerland showed higher Ca contents of >7 g Ca/kg DM in hay. The mineral contents of phosphorus and potassium were lower in hay from Switzerland (P: 1.8 +/- 0.7 g/kg DM, K: 15.4 +/- 5.1 g/kg DM) than from Bavaria (P: 3.8 +/- 0.6 g/kg DM, K: 20.0 +/- 6.0 DM), whereas the magnesium content of the hay showed no difference between the regions ( approximately 1.5 g Mg/kg DM). Very late first grass hay cuts showed low magnesium and calcium (<4 g/kg DM) contents. Further minerals in the hay for horses differed from those in dairy cattle in the same region. Fertilization showed only small effects on the mineral contents of the hay produced for horses. Therefore, in calculation of ration and production of supplements for horses, these differences should be taken into account.

These items formed the basis of a questionnaire sent to over 2800 managers at the SBUs level in the Indonesia’s oil and gas companies. The empirical result indicates that All Hayes and Wheelwright’s six principles collectively have positive impact on an overall construct that may be termed world-class company (WCC. Result also points out that Hayes and Wheelwright’s six principles can be reduced into four meaningful factors of world-class company—as operations strategies—for the Indonesia’s oil and gas industry— Workforce skills and capabilities, Management technical competence, Competing through quality, and Workforce participation. These meaningful factors of WCC were shown to be reliable and valid, and offer new insights into the understanding of operations strategy implementation in an oil and gas industry.Based on the oil and gas managers (the SBU level, operations strategies (four meaningful factors of WCC can be viewed as the effective use of production and operations capability and technology for achieving business and corporate goals. Operations strategy, therefore, is to help a company’s operations organization define the common ground where it can play a proactive and collaborative role with other company functions or cross-functional relationships (Hayes et al., 1996.  Oil and gas managers in Indonesia can use these meaningful factors in concert with other critical qual-ity management practices to help them in there word-class company initiatives.

    Occupancy models are widely used to analyze presence–absence data for a variety of taxa while accounting for observation error (MacKenzie et al. 2002, 2006; Tyre et al. 2003; Royle and Dorazio 2008). Hayes and Monfils (2015) question their use for analyzing avian point count data based on purported violations of model assumptions incurred by avian mobility. Animal mobility is an important consideration, not just for occupancy models, but for a variety of population and habitat models (Boyce 2006, Royle et al. 2009, Manning and Goldberg 2010, Dormann et al. 2013, Renner et al. 2015). Nevertheless, we believe the ultimate conclusions of Hayes and Monfils are shortsighted mainly due to a narrow interpretation of occupancy. Rather than turn away from the use of occupancy models, we believe they remain an appropriate method for analyzing many data sets collected from avian point count surveys. Further, we suggest that there is value in having a broader and more nuanced interpretation of occupancy that incorporates the potential for animal movement.

    Contaminated food is responsible for a significant amount of illnesses. In Morocco, it has become a worrying concern. Numerous awareness campaigns are conducted to warn the population against the risks of such scourge in ways that will prevent foodborne illness. Lawful commissions are in charge of examining and ensuring food safety in production and catering establishments, in addition to the assessment of food poisoning risks. The aim of this study is to evaluate the hygienic quality of food handling, preparation, and storage in catering establishments within Hay Hassani prefecture in Casablanca. During the period 2006-2012 a total of 1765 food samples were taken and examined for microbiological quality tests. As analyzed, 562 per 1765 samples are declared unhealthy for consumption. We note that some products were highly contaminated as compared to other products (p <0.001), specifically vegetable dishes, and meat dishes. In Hay Hassani district food is generally prepared and sold under unhygienic conditions, adequate corrective measures have been announced to improve hygienic practices.

    Full Text Available The aim of this study was to evaluate feed intake, digestibility, nitrogen balance, water balance, and performance of lambs fed diets containing old man saltbush hay associated with a concentrate. Thirty-two castrated feedlot Santa Inês lambs at approximately eight months of age, with 22 ± 1.97 kg body weight, were distributed into a completely randomized experimental design. Acid detergent fiber intake increased (P < 0.05, whereas non-fibrous carbohydrates intake decreased (P < 0.01. Inclusion of old man saltbush in the diet reduced (P < 0.01 the digestibility of dry and organic matter, neutral and acid detergent fiber, and non-fibrous carbohydrates. The intakes of digestible dry and organic matter, ether extract, total carbohydrates, and digestible non-fibrous carbohydrates also decreased (P < 0.01. Inclusion of old man saltbush did not influence water consumption from the trough by the sheep, averaging 4,327.20 mL/day?1. Body weight at slaughter and daily weight gain decreased linearly (P < 0.05 and feed conversion worsened as old man saltbush hay was added to the diet. Inclusion of old man saltbush at up to 40% replacing the concentrate in feedlot lamb diets does not compromise the performance of these animals.

    Full Text Available Reproductive performance of grain-fed reindeer {Rangifer tarandus was evaluated over a 2-year period. Groups of pregnant reindeer were fed one of three rations, (1 100% whole-grain barley, (2 98.9% whole-grain barley and 1.2% mineral and trace element supplement, and (3 70% whole-grain barley and 30% finely-chopped bluegrass hay. Reindeer fed unsupplemented whole-barley failed to produce a single live calf. The addition of mineral and trace element supplement to the ration did not result in any significant improvement in reproductive performance. Eighty-five percent of the reindeer consuming unsupplemented and supplemented all-barley rations became pregnant; however, 76% of the pregnancies resulted in stillborn calves. One-hundred percent of the cows maintained on the grain/hay ration produced live calves. We speculate that reproductive failure in reindeer cows maintained on all-grain rations is most likely a result of a diet induced disfunction in maternal rumen and/or carbohydrate metabolism rather than a micro-nutrient deficiency. More research is neeeded to determine which metabolic pathways are affected.

    Full Text Available The main requirement for preserving European hay meadows in good condition is through prerequisite cut management. However, monitoring these practices on a larger scale is very difficult. Our study analyses the use of MODIS vegetation indices products, namely EVI and NDVI, to discriminate cut and uncut meadows in Slovakia. We tested the added value of simple transformations of raw data series (seasonal statistics, first difference series, compared EVI and NDVI, and analyzed optimal periods, the number of scenes and the effect of smoothing on classification performance. The first difference series transformation saw substantial improvement in classification results. The best case NDVI series classification yielded overall accuracy of 85% with balanced rates of producer’s and user’s accuracies for both classes. EVI yielded slightly lower values, though not significantly different, although user accuracy of cut meadows achieved only 67%. Optimal periods for discriminating cut and uncut meadows lay between 16 May and 4 August, meaning only seven consecutive images are enough to accurately detect cutting in hay meadows. More importantly, the 16-day compositing period seemed to be enough for detection of cutting, which would be the time span that might be hopefully achieved by upcoming on-board HR sensors (e.g., Sentinel-2.

    The U.S. Geological Survey partners with organizations and experts to develop multiple hazard scenarios. The HayWired earthquake scenario refers to a rupture of the Hayward fault in the Bay Area of California and addresses the potential chaos related to interconnectedness at many levels: the fault afterslip and aftershocks, interdependencies of lifelines, wired/wireless technology, communities at risk, and ripple effects throughout today's digital economy. The scenario is intended for diverse audiences. HayWired analyses translate earthquake hazards (surface rupture, ground shaking, liquefaction, landslides) into physical engineering and environmental health impacts, and into societal consequences. Damages to life and property and lifeline service disruptions are direct causes of business interruption. Economic models are used to estimate the economic impacts and resilience in the regional economy. The objective of the economic analysis is to inform policy discourse about economic resilience at all three levels of the economy: macro, meso, and micro. Stakeholders include businesses, economic development, and community leaders. Previous scenario analyses indicate the size of an event: large earthquakes and large winter storms are both "big ones" for California. They motivate actions to reduce the losses from fire following earthquake and water supply outages. They show the effect that resilience can have on reducing economic losses. Evaluators find that stakeholders learned the most about the economic consequences.

    Because legumes are a very important feed source for ruminants, the aim of this study was to evaluate the ideal inclusion level of hay Arachis pintoi cv. Belmonte in sheep diets by measuring the dry matter intake (DMI), concentration of volatile fatty acids, ammonia-nitrogen concentration, ruminal pH and the in situ degradability of dry matter (DM) and crude protein (CP). In the experiment with four sheep, a 4 × 4 Latin Square design was used with four periods and four treatments (0%, 30%, 60% and 100% Arachis replacing grass hay). Significant interactions were observed between treatments and sampling times for ammonia-nitrogen and acetate, propionate and butyrate concentration and the acetate:propionate ratio. The ruminal pH and total volatile fatty acids concentration were not affected by interaction between treatments and sampling time. The degradation of DM and CP was similar, rising with the increasing content of Arachis, showing a linear effect. The treatment containing 60% of Arachis showed best results, with good levels of daily weight gain and higher ruminal concentrations of volatile fatty acids. The legume showed high levels of CP, high digestibility and appropriate levels of fibre, with excellent standards of degradation and ruminal characteristics. The use of the legume  Arachis for ruminants is a promising option of nutrient supply to meet production demands of these animals.

    Full Text Available The aim of this experiment was to evaluate, by means of the semi-automated in vitro gas production technique, fermentation kinetics of carbohydrates and degradability of dry matter (DM and organic matter (OM of diets containing oldman saltbush hay levels (8.4; 18.8; 31.2 and 48.3% associated to forage cactus in natura. Pressure readings of the gases were done with a pressure transducer at 2, 4, 6, 8, 10, 12, 17, 20, 24, 28, 34, 48, 72 and 96h post-inoculation. The rumen kinetics was described by the following parameters: maximum potential of gas production, lag time and production rates of gas (k, fibrous carbohydrates (FC and non-fibrous carbohydrates (NFC. It could be observed that the addition of oldman saltbush hay to the diets promoted a quadratic effect in the production of gases originated from NFC. However, there was no significant effect on the production of gases originated from FC and on production rates of gases from NFC and FC. The degradability of DM and OM did not differ due to the addition of oldman saltbush hay. The use of 8.4% hay and 74.9% forage cactus promoted the maximum potential of production of gases from the fibrous fraction of diets containing cactus and oldman saltbush hay.

    The study was carried out at Woreta, Ethiopia, to determine feed intake, digestibility, body weight (BW) change, and profitability of Farta sheep fed pasture hay alone or supplemented with graded levels of concentrate mix (CM) consisting of noug seed meal (NSM) and rice bran in 2:1 ratio. Twenty yearling intact male Farta sheep with BW of 16.9 +/- 1.68 kg (mean +/- SD) were used in randomized complete block design arranged into five blocks of four animals. The dietary treatments consisting of sole natural pasture hay (T1, control), hay +200 g of CM dry matter (DM) (T2, low), hay +300 g of CM DM (T3, medium), and hay +400 g of CM DM (T4, high) were randomly assigned to sheep within each block. Common salt and water were available to animals all the time. The supplements were offered twice daily in equal portions at 0800 and 1600 h. Supplementation with the CM increased (P profitability. Among the supplemented treatments, the high level of supplementation resulted in better (P profitability. Thus, the high level of supplementation is recommended based on biological performance and profitability under conditions of this study.

    Eight rumen cannulated Simmental heifers (BW = 281.4 ± 7.28 kg) were randomly assigned to one of four experimental treatments in a 4 × 4 replicated Latin square design to ascertain the effects of increasing levels of alfalfa hay on intake, sorting, and feeding behavior in comparison to barley straw as forage source. Treatments tested were four total mixed rations with: 1) 10% barley straw (10BS) with 7.0% NDF from forage, 2) 13% alfalfa hay (13AH) and less NDF from forage (5.7%) than 10BS, 3) 16% alfalfa hay (16AH) and the same NDF from forage (7.0%) as 10BS, and 4) 19% alfalfa hay (19AH) and more NDF from forage (8.3%) than 10BS. Each experimental period consisted of 3 wk for adaptation and 1 wk for sampling. Increasing the proportion of alfalfa hay in the diet linearly increased (P comparison to the 10BS diet. In the same way, intake of long, medium, and short particle size was greater in this diet. Moreover, heifers fed 19AH sorted for medium particle size and tended to sort for long and short particles size, and against fine particle size. Sorting behavior and meal length increased in the 19AH diet, which leads us to think that sorting feed ingredients requires time and therefore lengthens the meal. Time spent ruminating was greater in heifers fed 19AH, thus reducing the risk of ruminal acidosis when animals are fed high concentrate diets.

    In an Alpine environment, diets based on local forage resources are needed to maintain the link with the territory and confer special characteristics to typical cheeses. Harvesting at a late stage of maturity, high mechanical losses, and frequent rainfall often make the hay that is harvested of a poor quality. The aim of this study was to evaluate the effects of 2 different conservation methods (late hay, LH, vs. early haylage, ES) of natural permanent meadows on milk production in dairy cows, on the chemical and microbiological characteristics of the milk, and on the quality of the cheese over the winter period. Haylage and hay were harvested from the same permanent meadow at the Vittorino Vezzani experimental farm in Sauze d'Oulx (45 degrees 02'N, 6 degrees 53'E, Italy). The ES forage was cut 4 wk earlier than traditional hay, wilted for 30 h, baled at a dry matter (DM) content of about 50%, wrapped with 6 layers of stretch film, and stored in a protected area. The LH forage was harvested later, when the weather conditions were favorable and, after a 3-d wilting, it was baled and stored indoors. After an 8-mo storage period, the ES had a greater crude protein concentration, organic matter digestibility, and net energy for lactation than LH and a lower neutral detergent fiber and acid detergent fiber. Forty multiparous lactating Aosta Red Pied cows were used in a 19-d period crossover design to assess the nutritional value of the stored forages. The diets included ES fed ad libitum and 3.5 kg of DM per cow of concentrate or LH fed ad libitum and 5.1 kg of DM per cow of concentrate. The dietary DM was 90.1% for the LH and 59.9% for the ES. The diets contained 12.6 and 13.0% crude protein and 48.6 and 48.0% neutral detergent fiber, for the LH and ES, respectively. The forage intake was greater in the ES treatment than in the LH treatment. The ES treatment produced more milk (1.7 kg/d) and more 3.5% fat-corrected milk (1.5 kg/d) than the cows on the LH treatment. The

    Wetland catchments are major ecosystems in the Prairie Pothole Region (PPR) and play an important role in greenhouse gases (GHG) flux. However, there is limited information regarding effects of land-use on GHG fluxes from these wetland systems. We examined the effects of grazing and haying, two common land-use practices in the region, on GHG fluxes from wetland catchments during 2007 and 2008. Fluxes of methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2), along with soil water content and temperature, were measured along a topographic gradient every other week during the growing season near Ipswich, SD, USA. Closed, opaque chambers were used to measure fluxes of soil and plant respiration from native sod catchments that were grazed or left idle, and from recently restored catchments which were seeded with native plant species; half of these catchments were hayed once during the growing season. Catchments were adjacent to each other and had similar soils, soil nitrogen and organic carbon content, precipitation, and vegetation. When compared with idle catchments, grazing as a land-use had little effect on GHG fluxes. Likewise, haying had little effect on fluxes of CH4 and N2O compared with non-hayed catchments. Haying, however, did have a significant effect on combined soil and vegetative CO2 flux in restored wetland catchments owing to the immediate and comprehensive effect haying has on plant productivity. This study also examined soil conditions that affect GHG fluxes and provides cumulative annual estimates of GHG fluxes from wetland catchment in the PPR.

    Distinguishing organic and conventional products is a major issue of food security and authenticity. Previous studies successfully used stable isotopes to separate organic and conventional products, but up to now, this approach was not tested for organic grassland hay and soil. Moreover, isotopic abundances could be a powerful tool to elucidate differences in ecosystem functioning and driving mechanisms of element cycling in organic and conventional management systems. Here, we studied the δ(15)N and δ(13)C isotopic composition of soil and hay samples of 21 organic and 34 conventional grasslands in two German regions. We also used Δδ(15)N (δ(15)N plant - δ(15)N soil) to characterize nitrogen dynamics. In order to detect temporal trends, isotopic abundances in organic grasslands were related to the time since certification. Furthermore, discriminant analysis was used to test whether the respective management type can be deduced from observed isotopic abundances. Isotopic analyses revealed no significant differences in δ(13)C in hay and δ(15)N in both soil and hay between management types, but showed that δ(13)C abundances were significantly lower in soil of organic compared to conventional grasslands. Δδ(15)N values implied that management types did not substantially differ in nitrogen cycling. Only δ(13)C in soil and hay showed significant negative relationships with the time since certification. Thus, our result suggest that organic grasslands suffered less from drought stress compared to conventional grasslands most likely due to a benefit of higher plant species richness, as previously shown by manipulative biodiversity experiments. Finally, it was possible to correctly classify about two third of the samples according to their management using isotopic abundances in soil and hay. However, as more than half of the organic samples were incorrectly classified, we infer that more research is needed to improve this approach before it can be efficiently

    Full Text Available One of the main concerns is the nature of the missing values. Let’s consider extremes for simplicity. If missing at random we have not to care about. But if missing shows structures that covariate with substantive variables we have to make decisions. There are, in fact, several options to take. We are speaking about one country, one mode. But if you go cross-cultural (or more precisely, cross-state nations and mixed modes many questions raise. For example, the simple one. What are we comparing? Reports and books usually go straight into variables distributions and coefficient comparisons. This is possible because the annalist presume "tabula rasa" effect from data collections procedures. But this is not, frequently, the real situation. This paper will expose the mixed missing mode imprint in international surveys. This will help to evaluate how deal with this problem. Also, to consider the real meaning of observed cross-national differences. | Una de las principales preocupaciones en la investigación mediante encuestas es la naturaleza de los valores perdidos. En el caso de que sean de ocurrencia aleatoria no generan problemas excesivos. Por el contrario, si los valores perdidos muestran estructuras que covarían con variables relevantes deben tomarse decisiones fundamentales. Eso en el caso de una encuesta en un país. Pero si se trata de una encuesta comparada, efectuada en varios países y además con modos mixtos de recolección de datos, la cuestión deviene bastante más complicada. Entre las preguntas surge la más evidente ¿Qué se está comparando realmente? Con frecuencia los investigadores emplean directamente distribuciones de frecuencia y coeficientes, haciendo “tabula rasa” de otros factores que puedan generar diferencias. Esta investigación muestra como la interacción entre las estructuras de valores perdidos, el modo de recolección de datos y el hecho de la cross-culturalidad es significativa.

Los datos fueron recolectados en el período de 2000 a 2003, por medio de observaciones de campo, análisis de manuales y el libro de registro del turno de las enfermeras. El análisis reveló que el ritual de internación es hecho desde la lógica de la institución, de los profesionales médicos y del saber construido en relación al sujeto. El examen da visibilidad al poder médico, examina el cuerpo y objetiva el paciente sujetándolo a las verdades de un campo de conocimiento. El cuidado de enfermería se expresa en los ejercicios de poder, rituales, dispositivos, simbolizaciones y juegos de intereses que circulan, traman y lo sostienen en el hospital. Por lo tanto, el cuerpo producido es fragmentado, con dominios múltiples, disciplinado, vigilado; tomado por la enfermedad. El hospital se reveló como un cuerpo "construido", al mismo tiempo que "construye" los cuerpos.

    Full Text Available El uso de la bicicleta como modo de transporte se asocia con numerosos beneficios ambientales y sociales, no obstante, se desconoce cuáles son los más valorados por los ciclistas. El objetivo de este estudio fue conocer en qué medida el Sistema de Transporte Público de Bicicletas (STPB de la ciudad de Buenos Aires produjo impactos positivos sobre los aspectos que las personas valoran en el momento de viajar, analizando si estas evaluaciones varían en función de la intensidad de uso del STPB. Para ello, se diseñó un cuestionario basado en un estudio sobre la calidad de vida residencial que fue aplicado a 161 usuarios del STPB. Los resultados indicaron que los aspectos del viajar: rapidez, control del horario de llegada, ahorro de dinero y en menor medida la salud, fueron muy importantes para los usuarios y fueron los que más mejoraron a partir del uso del STPB. Asimismo, las personas que usan el sistema con mayor intensidad son las que perciben más beneficios sobre los aspectos no instrumentales del viajar como el entretenimiento y la comodidad. Estos resultados sugieren que para lograr que las personas realicen un cambio sustentable en sus comportamientos de movilidad es necesario mantener las ventajas instrumentales que ofrece el servicio de bicicletas compartidas sobre los otros medios de transporte.

    Full Text Available La inserción de un Resonador Helmholtz (RH en las paredes laterales de un tubo, con ondas estacionarias en su interior, logra suprimir uno o más de sus modos resonantes si se elige adecuadamente la frecuencia del resonador. El RH puede actuar también como filtro de ondas propagantes.' En este caso, el RH atenua las ondas en un rango de frecuencia muy selectivo. En la mayoría de los textos de acústica, solamente se desarrolla la teoría que explica el filtrado de ondas propagantes. Sin embargo, en los laboratorios de física basica, donde se dispone solamente de tubos de Kundt de pequeña longitud, no es simple realizar un arreglo experimental que asegure la presencia de ondas propagantes puras en su interior. La falta de una teoría para ondas estacionarias y las dificultades experimentales que señalamos han producido algunas confusiones en trabajos que tratan sobre el tema. En este artículo se presenta un modelo teórico que describe satisfactoriamente el comportamiento del RH cuando funciona como filtro de ondas estacionarias y se marcan las diferencias con la situación en que opera como filtro de ondas propagantes.

    Selenium (Se) is an essential trace mineral important for immune function and overall health of cattle. The nasopharyngeal microbiota in cattle plays an important role in overall respiratory health, especially when stresses associated with weaning, transport, and adaptation to a feedlot affect the normal respiratory defenses. Recent evidence suggests that cattle diagnosed with bovine respiratory disease complex have significantly less bacterial diversity. The objective of this study was to determine whether feeding weaned beef calves Se-enriched alfalfa (Medicago sativa) hay for 9 weeks in a preconditioning program prior to entering the feedlot alters nasal microbiota. Recently weaned beef calves (n = 45) were blocked by sex and body weight, randomly assigned to 3 treatment groups with 3 pens of 5 calves per treatment group, and fed an alfalfa hay based diet for 9 weeks. Alfalfa hay was harvested from fields fertilized with sodium selenate at a rate of 0, 45.0 or 89.9 g Se/ha. Blood samples were collected biweekly and analyzed for whole-blood Se concentrations. Nasal swabs were collected during week 9 from one or two calves from each pen (total n = 16). Calculated Se intake from dietary sources was 3.0, 15.6, and 32.2 mg Se/head/day for calves consuming alfalfa hay with Se concentrations of 0.34 to 2.42 and 5.17 mg Se/kg dry matter, respectively. Whole-blood Se concentrations after 8 weeks of feeding Se-fertilized alfalfa hay were dependent upon Se-application rates (0, 45.0, or 89.9 g Se/ha) and were 155, 345, and 504 ng/mL (PLinear Microbial DNA was extracted from nasal swabs and amplified and sequenced.

    Full Text Available The objective of this study was to evaluate the effect of inclusion of exhausted substrate of Pleurotus ostreatus on the in vitro fermentation of Brachiaria brizantha hay-based diets. The experiment was conducted using the semi-automated gas production technique. The ruminal inoculum was collected from three fistulated cattle kept on Brachiaria brizantha pasture. Brachiaria brizantha hay and exhausted substrate of Pleurotus production were used for composition of the diets: ES (100% exhausted substrate, BH (100% Brachiaria brizantha hay, ES5 (5% ES + 95% BH, ES20 (20% ES + 80% BH, and ES30 (30% ES + 70% BH. The experimental design was a 5x3 factorial scheme consisting of five treatments and three ruminal inocula. The degradation kinetics of dry matter (DM was determined after 96 hours of fermentation [D (96h]. No significant differences in the cumulative volume of gas (A were observed between BH (262.6 mL/g DM, ES5 (284.3 mL/g MS, ES20 (256.6 mL/g MS and ES30 (261.7 mL/g MS, indicating that inclusion of the substrate did not affect hay fermentation. A lower gas volume (165.9 mL and lower degradability (52% were observed for the ES diet, showing a lower nutritional value of this substrate compared to Brachiaria brizantha hay, probably due to the action of enzymes that degrade structural carbohydrates found in the mycelia of Pleurotus. The ES diet exhibited a shorter colonization time (L=2.6 h; P<0.05, a finding that may be attributed to the interaction between the mycelium and substrate, facilitating initial colonization. The inclusion of exhausted substrate did not increase microbial growth or degradation compared to the BH diet, but seems to have favored initial colonization of this substrate. The use of ES does not negatively affect colonization and may be used as an ingredient of ruminant diets.

    Full Text Available Six grass species (Pennisetum purpureum, Pennisetum purpureophoides, Sorghum sudanense, Brachiaria brizantha, Imperata cylindrica, and Panicum maximum were harvested at 49 days and preserved as silage or as hay. Samples of silage and hay were evaluated by an in vitro gas production and in vitro nutrient degradability. Total gas production at 24 and 48 h as well as CH4 were higher (P<0.01 in silage than in hay. Brachiaria brizantha had the highest (P<0.01 gas production compared to other species, whereas P. purpureum had the highest CH4 production (mM/g organic matter degraded. Dry matter (DM and organic matter (OM degradations were higher (P<0.01 in silage than hay. When compared with hay, silage had higher (P<0.01 ammonia-N concentration (20.3 vs. 10.6 mg/100 ml and higher (P<0.05 butyric acid concentration (7.9 vs. 7.0 mM. Non-fiber carbohydrate (NFC and crude protein contents were positively correlated with gas production (r = 0.51; P<0.05 and CH4 production (r = 0.64; P<0.01 at 48 h of in vitro incubation.

Median numbers of viable anaerobic bacteria adherent to the plant particles (cells/g wet weight of rumen solids, growing on a habitat simulating medium (M8V, were significantly higher (P = 0.05 in the rumen of reindeer fed lichen (26.5 x 109- 53.0 x 109 and hay (4.0 x 109- 40.5 x 109, compared to reindeer fed silage (1.15 x 109 - 3.25 x 109. Anaerobic bacterial strains (n = 551 from the plant particles obtained from the rumen of the nine reindeer examined, were isolated using an acid swollen cellulose medium (M8SC and tested for their ability to hydrolyse carboxymethyl cellulose (CMC. The proportion of CMC hydrolysing adherent bacteria isolated from M8SC was significantly higher in reindeer fed hay (21.5% compared ro animals fed lichen (5.3% and silage (2.7% (P = 0.05. The CMC hydrolysing bacterial srrains (n=42 isolated from reindeer fed hay where characterised as non-cellulolytic Butyrivibrio fibrisolvens (9.5%, cellulolytic B. fibrisolvens (50.0%, Clostridium sp. (2.4% and unknowns (38.1%, while CMC hydrolysing strains (n=11 isolated from animals fed lichen and strains (n=4 isolated from animals fed silage where all characterised as B. fibrisolvens. None of the bacterial strains isolated from the rumen solids of reindeer fed lichen or silage were found to be cellulolytic. This study suggests that both lichen and timothy silage have a negative influence, compared to hay, on the numbers of cellulolytic bacteria adherent to the plant particles in the rumen of reindeer.

The present text is a fragment of a master’s research, developed within the Observatory of Education Program – OBEDUC (Brazil, which focuses on the practices of mathematical literacy and teacher training. The project team is composed of five teachers from the public-school literacy cycle, four postgraduate students, and four university professors. In bi-weekly meetings the group works to study, to select tasks that will be performed in classrooms, and to share narratives about the work accomplished by the teachers in their respective schools. The text focuses on the movement of meanings during the process of teaching and learning geometric concepts with a third-grade student diagnosed with Autism Spectrum Disorder. The results show that the learning possibilities of all students, with or without disabilities, are intertwined with the conditions offered by the surrounding environment. Therefore, the intersubjective relations that occur during the activities mediated by words and technical-semiotic instruments are emphasized. In this sense, the school has a key role. By teaching, in the context of school inclusion policy, the challenge for teachers is to create the educational conditions for every student in the classroom, while not losing sight of their singularities.

    Full Text Available It was evaluated four levels of silk flower (Calotropis procera S.W. hay (SFH as a substitute of sorghum (Sorghum bicolor hay (SBH in diet for lambs. Nutritional value of silk-flower hay was determined based on aparent digestibility and on metabolic, productive and economical performance of Santa Inês lambs. It was used twenty-four castrated males at 15.72 ± 1.92 kg body weight randomly distributed in four diets with silk-fklower and sorghum hay ratios (100:0, 66:33, 33:66, 0:100, and supplemented with a concentrate mixture based on 50% roughage:50% concentrate (weight/weight. Increase in the levels of silk-flower hay in the diet reduced weight gain and nutrient intake and it increased feed conversion and digestibility coeficients of all the nutrients. Nitrogen balance was similar in all levels of silk-flower hay, although there was a tendency of reduction in nitrogen retention at levels 66% and 100% of silk-flower hay. At the levels 0 and 33% of silk-flower hay in the diet, dry matter ingestion (170 and 180 g/day, daily average weight gain (84 and 89 g/kg0.75and feed conversion (4.99 and 5.02 were satisfactory.

    Full Text Available Este artículo se basa en la hipótesis de que la estructura de capital de las PyME está afectada por la ubicación territorial de las empresas. Este comportamiento podría estar motivado por las similitudes en las políticas financieras de las empresas ve-cinas, ya que comparten características financieras, jurídicas y de entorno econó-mico, y debido a los vínculos comerciales y financieros que existen entre ellas. Para contrastar esta idea, aplicamos una metodología econométrica espacial a una muestra de 23 279 empresas manufactureras españolas. Nuestros hallazgos confir-man que las proporciones de endeudamiento total no se distribuyen aleatoriamente en el territorio español, sino que hay regiones con un endeudamiento alto (bajo que tienden a estar rodeadas de zonas con una deuda alta (baja. Por otra parte, los determinantes tradicionales de la estructura de capital cambian un poco cuando se considera el efecto de interacción regional entre unidades productivas. Por tanto, resulta necesario considerar estos efectos en los modelos financieros de estructura de capital para evitar estimaciones erróneas.

    The objective of this study was to determine endogenous phosphorus excretion in sheep fed with different diets. Sixteen male growing sheep, received a basic diet with: 42% hydrolyzed sugarcane bagasse (HSB), 45% lucerne hay (LH) plus 14% hydrolyzed sugarcane bagasse, and 30% citrus pulp (CTP) plus 40% hydrolyzed sugarcane bagasse. A dose of 7.7 MBq 32 P was injected into the left jugular vein of each animal. The P endogenous fecal losses were: 1.69, 2.50, 2.33 and 1.45 g/animal for treatments HSB, LH, and CTP respectively (P>0.05). The type of diet influenced slight endogenous P excretion but altered excretion of P in urine. Endogenous P excreted in feces (P F ) comes mainly from saliva and represents an important loss of P. The estimation of net requirements of phosphorus (P) for ruminants includes endogenous losses, which is also essential for calculating true absorption of this mineral. Physical structure of the feed may influence endogenous losses, altering the metabolism of P and also the demand of this mineral, therefore being important to know how different feeds affect endogenous P losses.

Eighteen ewes with 39.7±4 kg mean body weight, kept in individual pens, were randomly assigned to one of the following treatments: T1: TWH, T2: TWH plus 200 g DW, T3: TWH plus 300 g DW. The ewes were synchronized with 40 mg fluorogestone acetate (FGA and 400 UI equine chorionic gonadotropin (eCG. Data were analyzed as a completely randomized design using the GLM procedure. DW supplementation had no effect on dry matter intake (p>0.05; however, a slight decrease of TWH intake was observed as DW supplementation increased. No differences (p>0.05 were found in the beginning of estrus, percentage of ewes presenting it, its duration, or pregnancy rate. There were no differences (p>0.05 on P4 concentration among treatments, or treatmentxperiod interaction (p>0.05.

The study was based on survey data and quotation activities involving price from the land preparation (repair, planting and fertilization to the processing of the product at the factory (extrusion and marketing. Transportation costs and taxes were also considered. Discounted Cash Flow (30 years was used to calculate the profitability indicator and the Profit and Loss Statement (PLS. Calculations were developed using Microsoft Office Excel® spreadsheets. Three production scenarios were simulated with different consumer prices: Scenario 1 - equivalent to the complete diet, where the ingredients are supplied together, but purchased separately; Scenario 2 - Considering a value 10% higher than the complete diet; Scenario 3 - Considering a value 20% higher than the complete diet. We observed that the project was economically viable in the three suggested scenarios with positive Net Present Value, Internal Rate of Return greater than 9.4% and payback of 11 to 2 years. The results enable us to conclude that the product may be a promising investment for both product quality and ease of use as the rapid return on invested capital.

    Full Text Available La obra de Marx ha suscitado una  añeja polémica entre sus estudiosos. Algunos han mantenido que el lenguaje desarrollado en ella es estrictamente explicativo. Dicho lenguaje expresaría ante todo un saber científico expurgado de todo contenido moral (sobre la estructura del capital, las fuerzas que causan la dinámica social y las leyes que la rigen. En el otro extremo, en cambio, otros han argüido que en Marx hallamos más bien un lenguaje ético orientado a denunciar los crímenes y miserias de una determinada formación social con el fin de oponerle otra. En este artículo defiendo la idea de que en la obra de Marx hay elementos tanto para afirmar una cosa como la otra. Sin embargo, argumento que la actualidad del pensamiento marxista  reside esencialmente en los elementos éticos y normativos que configuran la dimensión moral de su planteamiento.

    Full Text Available A espiritualidade inaciana, condensada nos Exercícios Espirituais de Santo Inácio, possibilita a produção de uma teologia profético-espiritual. O profetismo inaciano sintoniza-se com a grande tradição dos profetas bíblicos e seu modo peculiar de fazer e explicitar a experiência de Deus. A espiritualidade inaciana reflete-se na produção teológica de quem a assumiu como pauta de vida cristã. A teologia é produzida a partir do centramento em Deus, permitindo ao teólogo contemplar a realidade com o olhar de Deus. Livre diante das criaturas e atento aos anseios dos empobrecidos, o teólogo estará em condições de julgar a realidade a partir do projeto de Deus. A consciência de ser chamado para o serviço do povo leva-o a ser otimista em relação à humanidade. A teologia se faz como discernimento espiritual da história. ABSTRACT: Condensed in the Spiritual Exercices of Saint Ignatius, Ignatian spirituality fosters the production of a prophetic-spiritual theology. Ignatian prophetism gets on with the great tradition of biblical prophets and their peculiar way of having and explaining the experience of God. Ignatian spirituality is expressed on the theological production of the one who assumes it as program of Christian life. Theology is done from the perspective of God’s centrality allowing the theologian to contemplate reality with God’s eyes. Freed from creatures and paying attention to the poor’s needs the theologian will always be able to judge reality from God’s project. His/her conscience of being called to serve his/her people transforms the theologian into an optimistic about humanity. Theology is done as a spiritual discernment on history.

    Obesity and gastric ulceration are highly prevalent in horses. Management modifications for preventing squamous gastric ulceration include frequent feeding and free access to pasture; however, these practices may predispose horses to obesity. To compare the percentage of hay consumed, intragastric pH and horse activity between feeding from the ground and a hay grid feeder. Crossover experimental study. A pH electrode was inserted into the stomach to record the intragastric pH for 48 h. Horses received 1% of their body weight in grass hay twice a day. Horses were assigned to be fed from the ground or a commercial hay grid feeder for 24 h and then switched to the opposite protocol for an additional 24 h. Horses were continuously video-recorded and the percentage of time spent eating or drinking, walking or standing, and lying down were calculated. Two point data were compared by paired t test and pH over time was compared by repeated measures ANOVA. Horses consumed significantly greater amounts of grass hay when fed on the ground compared with a hay grid feeder (n = 9; PpH values (n = 6; P = 0.97), mean intragastric pH over time (n = 6; P = 0.45) the length of time the pH was below 4.0 (n = 6; P = 0.54), and the percentage of time horses spent eating or drinking (n = 9; P = 0.52), walking or standing (n = 9; P = 0.3), or lying down (n = 9; P = 0.4). Within each group horses spent more time eating during the day compared with the night (n = 9; hay grid feeder P = 0.003; ground feeding P = 0.007). The hay grid feeder studied may be used to reduce the amount of hay ingested by horses without reducing the time horses spend eating. © 2013 EVJ Ltd.

    The aims of this study were to monitor electromyographic (EMG) activity of masseter muscle in healthy horses fed (i) different types of roughage and (ii) maize after different hay allocations. Four horses were offered the following three diets ad libitum: hay, haylage or straw/alfalfa chaff (SAC). In a second trial, four horses were fed cracked maize (CM) and hay in three different orders: (i) CM after a 12-h overnight fast; (ii) CM immediately after restricted hay intake (0.6 kg hay/100 kg BW); or 3) CM after hay intake ad libitum. The activity of the masseter muscle was determined by EMG (IED(®) ), and the following were measured: amplitude (muscle action potential = MAP, maximum voltage) and duration of MAP (s). The intake of hay or haylage was associated with intense masseter muscle activity (MAP: hay, 10 ± 1.7 V; haylage, 11 ± 3.3 V; and duration of MAP: hay, 0.31 ± 0.04 s; haylage, 0.30 ± 0.04 s). Similar intense chewing was measured for SAC (MAP 13 ± 3.8 V), although duration of the chewing cycle was relatively short (0.22 ± 0.03 s, diet p haylage or SAC was associated with intensive masseter muscle activity that was likely to stimulate salivary flow rate. In contrast to roughage, concentrates like CM are consumed rapidly with less intensive masseter muscle activity. This situation is associated with a low salivary flow that may have an adverse effect on gastric function. © 2012 Blackwell Verlag GmbH.

    It was desired to observe the behavior of a two bladed wind turbine where the tower first bending natural frequency is less than twice the rotor speed. The system then passes through resonance when accelerating to operating speed. The frequency of the original Mod-O tower was reduced by placing it on a spring fixture. The fixture is adjustable to provide a range of tower bending frequencies. Fixture design details are given and behavior during initial operation is described.

    Full Text Available Este artigo debruça-se sobre as recentes reformas desenvolvidas no sector hospitalar português. Trata-se da implementação de princípios da Nova Gestão Pública, não sendo, por isso, uma opção política exclusiva nem inovadora em Portugal. Decorrente do processo de tendencial empresarialização dos hospitais públicos, elege-se como objectivo perceber em que medida estas reformas afectam o significado da prestação pública de cuidados. A abertura às regras de mercado e, consequentemente, a um contexto de concorrência entre os prestadores públicos e entre os prestadores públicos e privados associa a empresarialização à mercadorização da prestação pública de cuidados. Não estando em causa o fim de um modo de produção de saúde estatal, apresentam-se argumentos que parecem comprovar que estas reformas afectam conceptualmente o modo de produção de saúde estatal definido por Boaventura de Sousa Santos em 1987, esbatendo algumas das fronteiras em relação ao modo de produção de saúde capitalista.

    The concept of a one-bladed horizontal-axis wind turbine has been of interest to wind turbine designers for many years. Many designs and economic analyses of one-bladed wind turbines have been undertaken by both United States and European wind energy groups. The analyses indicate significant economic advantages but at the same time, significant dynamic response concerns. In an effort to develop a broad data base on wind turbine design and operations, the NASA Wind Energy Project Office has tested a one-bladed rotor at the NASA/DOE Mod-O Wind Turbine Facility. This is the only known test on an intermediate-sized one-bladed rotor in the United States. The 15.2-meter-radius rotor consists of a tip-controlled blade and a counterweight assembly. A rigorous test series was conducted in the Fall of 1985 to collect data on rotor performance, drive train/generator dynamics, structural dynamics, and structural loads. This report includes background information on one-bladed rotor concepts, and Mod-O one-bladed rotor test configuration, supporting design analysis, the Mod-O one-blade rotor test plan, and preliminary test results.

  1. Hay fever, a post industrial revolution epidemic: a history of its growth during the 19th century.

    Although other forms of allergic disease were described in antiquity, hay fever is surprisingly modern. Very rare descriptions can be traced back to Islamic texts of the 9th century and European texts of the 16th century. It was only in the early 19th century that the disease was carefully described and at that time was regarded as most unusual. By the end of the 19th century it had become commonplace in both Europe and North America. This paper attempts to chart the growth of hay fever through the medical literature of the 19th century. It is hoped that an understanding of the increase in prevalence between 1820 and 1900 may provide an insight for modern researchers and give some clues into possible reasons for the epidemic nature of the disease today.

    Children with asthma, hay fever, and food allergy may have several factors that increase their risk of speech disorder, including allergic inflammation, ADD/ADHD, and sleep disturbance. However, few studies have examined a relationship between asthma, allergic disease, and speech disorder. We sought to determine whether asthma, hay fever, and food allergy are associated with speech disorder in children and whether disease severity, sleep disturbance, or ADD/ADHD modified such associations. We analyzed cross-sectional data on 337,285 children aged 2-17 years from 19 US population-based studies, including the 1997-2013 National Health Interview Survey and the 2003/4 and 2007/8 National Survey of Children's Health. In multivariate models, controlling for age, demographic factors, healthcare utilization, and history of eczema, lifetime history of asthma (odds ratio [95% confidence interval]: 1.18 [1.04-1.34], p = 0.01), and one-year history of hay fever (1.44 [1.28-1.62], p speech disorder. Children with current (1.37 [1.15-1.59] p = 0.0003) but not past (p = 0.06) asthma had increased risk of speech disorder. In one study that assessed caregiver-reported asthma severity, mild (1.58 [1.20-2.08], p = 0.001) and moderate (2.99 [1.54-3.41], p speech disorder; however, severe asthma was associated with the highest odds of speech disorder (5.70 [2.36-13.78], p = 0.0001). Childhood asthma, hay fever, and food allergy are associated with increased risk of speech disorder. Future prospective studies are needed to characterize the associations. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    This work presents the results of a 4-year study (2009-2012) investigating the mixing and photoreactivity of dissolved organic matter (DOM) in the Nelson/Hayes estuary (Hudson Bay). Dissolved organic carbon (DOC), colored DOM, and humic-like DOM decreased with increasing salinity (r2 = 0.70-0.84). Removal of DOM was noticeable at low to mid salinity range, likely due to degradation and/or adsorption to particles. DOM photobleaching rates (i.e., decrease in DOM signal resulting from exposure to solar radiation) ranged from 0.005 to 0.030 h- 1, corresponding to half-lives of 4.9-9.9 days. Dissolved organic matter from the Nelson and Hayes Rivers was more photoreactive than from the estuary where the photodegradation of terrestrial DOM decreased with increasing salinity. Coincident with the loss of CDOM absorption was an increase in spectral slope S, suggesting a decrease in DOM molecular weight. Marked differences in photoreactivity of protein- and humic-like DOM were observed with highly humidified material being the most photosensitive. Information generated by our study will provide a valuable data set for better understanding the impacts of future hydroelectric development and climate change on DOM biogeochemical dynamics in the Nelson/Hayes estuary and coastal domain. This study will constitute a reference on terrestrial DOM fate prior to building additional generating capacity on the Nelson River.

    The influence of gamma irradiation on microbial load and chemical quality of camel hay (Cymbopogon schoenanthus) leaves was evaluated at doses of 0, 5,10, and 15 kGy in a cobalt-60 package irradiator. The results revealed that, immediately after irradiation, gamma irradiation was found to cause significant reduction in microbial load proportionate to the doses delivered. TLC analysis indicated that irradiation of camel hay leaves extract with 15 kGy doses of gamma radiation had no effect on flavonoids concentrations, however, increase in total phenols and tannins was observed. In addition, the chemical constituents of camel hay leaves as represented by HPLC retention time (min) at different wave lengths showed that the compounds of retention time 8.42, 29.08, 8.38, 16.93, 14.80 and 42.80 min remained approximately unchanged, while the compound of retention times 16.95 min was eliminated. The compounds of retention times 9.66, 2.03 and 29.35 min were decreased from 16.56 to 11.77, 14.06 to 9.88 and 8.25 to 2.88 min respectively. An increase in the chemical constituents, was observed in the compounds of the retention times 14.37 and 35.42 min from 33.76 to 40.11 and 5.64 to 10.05, respectively. (Author)

    Full Text Available An experiment was conducted to study the effects of replacing alfalfa hay with different levels of sunflower residual silage (SRS on fattening performance of Azari male buffalo calves. Thirty calves with 138.33 Kg of BW fed experimental diets in a completely randomized design with 5 groups and 6 replicates. The five groups (1, 2, 3, 4 and 5 included 0 (control, 25, 50, 75 and 100 percent replacement of alfalfa hay with SRS, respectively in basal diet. The results showed that dry matter intake (DMI was significantly different between the groups (p<0.05. The highest and the lowest DMI were shown at the groups 1 and 5, respectively, however there was no significant difference between the groups 2, 3, and 4 with control. Daily weight gain (DWG was significantly different between the groups (p<0.05. Group 5 had significantly lower DWG than groups 1, 2 and 3, furthermore there were no significant difference between groups 1, 2, 3 and 4. Feed conversion ratio (FCR was significantly different among the groups (p<0.05. There was no significant difference among the groups 1, 2, 3 and 4. But these groups had significantly better FCR than the group 5. The best FCR was obtained for group3. It may conclude that alfalfa hay can be substituted with SRS at 50 % level with no negative effects on Azari male buffalo calves fattening performance.

    A control of sliding ways in discreet time for non-linear discreet systems is designed, also the technique of the control by histograms for non-linear discreet systems was developed, and an observer of reduced order was developed for non-linear electromechanical discreet systems. All these techniques are applied to a non-linear discreet model of an induction motor that was found here, that posses electrical and mechanical dynamics, in which the load pair is considered an unknown disturbance. With complete measurements of the states are satisfied the pursuing of the rotor velocity and the amplitude of the magnetic flux of the rotor, where the unknown load does not affect the velocity regulation. Next, an observer of reduced order is implemented where the velocity and current measurements are employed to consider the load pair and the flows that are very difficult to measure. The proposed method has a design and stability procedure of direct analyses, conserving a simple structure of the control law. The simulations predict that the system is robust with respect to several types of load pairs. The responses of velocity and amplitude of the rotor flow and the entrance references evolved very well. These references have a linear dynamics of second order with time constants that can be chosen by the motor user. The practical aspects for a future digital implementation of the control law are considered, including the velocity and currents sensors, the preparation of signals, the transformation of the current in the frame of stationary reference, PWM and inverter modules, which were seen in detail. The experimental results are left as a future work.

    The objective of this study was to investigate the effect of an abrupt change from grass hay (81% DM) to grass silage (36% DM) or grass haylage (55% DM), fed at similar DM intakes, and to compare the effects of silage and haylage on the composition and activities of the colon microflora. The forages were from the same swath harvested on the same day. Four adult colon-fistulated geldings were randomly assigned to diets in a crossover design. The study started with a preperiod when all 4 horses received the hay diet, followed by an abrupt feed change to the haylage diet for 2 horses and the silage diet for 2 horses. All 4 horses then had a new second preperiod of hay, followed by an abrupt feed change to the opposite haylage and silage diet. The periods were 21 d long, and the forage-only diets were supplemented with minerals and salt. The abrupt feed changes were made at 0800 h. Colon samples were taken before the abrupt feed change, 4 and 28 h after the feed change, and 8, 15, and 21 d after the feed change, all at 1200 h. Colon bacterial counts, VFA, pH, and DM concentrations were unchanged throughout the first 28 h after the abrupt feed change from hay to haylage and silage. Also, fecal pH and DM concentrations were unchanged during the first 28 h. During the weekly observations, colon lactobacilli counts increased (P = 0.023) in horses receiving the silage diet and were greater than on the haylage diet at 21 d. Streptococci counts decreased (P = 0.046) in horses receiving the haylage diet and were less than on the silage diet at 15 and 21 d. Total VFA concentrations and colon and fecal pH did not differ between diets and were unchanged throughout the weekly observations. The DM concentration of colon digesta and feces decreased (P = 0.030 and 0.049, respectively) on both diets during the weekly observations. The results suggest that in horses fed at the maintenance level of energy intake, an abrupt feed change from grass hay to grass silage or grass haylage from

    Introduction the first months of life are the most vulnerable period in allergic disease development and it is not clear enough whether inhalant pollen allergen exposure predisposes the risk of consequent allergic reactions. To study the clinical and epidemiological criteria of hay fever with special emphasis on investigation of the relationship between the date of birth and seasonal allergic rhinitis development in children and adolescents in Kazakhstan. The prospective hospital based study was conducted during pollen season from the beginning of May to the end of October in two consequent years 2010 and 2011. 184 children and adolescents at the age of 1--17 years underwent consultations and skin prick tests in the allergological center "Umit" (Astana, Kazakhstan). Special allergological questionnaires were developed and adapted for local residents. The assessment of symptoms severity was performed using a scoring system. Skin prick tests were performed in 112 patients. The number of patients was explained by the age limitations. Correlation analysis between skin prick test results and the month of birth were performed. It was found that in summer months there were the highest number of patients with seasonal allergic rhinitis 68 (36.9%), followed by spring 44 (23.9%), then autumn 37 (20.1%) and the lowest percent of patients 35 (19.1%) was born in winter. Rhinoconjunctival syndrome was diagnosed in 180 (97.8%) patients, pollen induced bronchial asthma in 76 (41.3%) and pollen induced urticaria in 35 (19.0%) patients. Mono sensitization among Kazakhstan children and adolescents was determined only to several species of the plants, mainly to Artemisia Absinthium (68.2%) and Sunflower (25.7%), whereas multiple sensitization to the mix of weeds was determined in 75 (66.9%) patients, to the mix of meadow grass in 33 (29.4%), mix of meadow grass+mix of weeds in 25 (22.3%) and mix of trees in 9 (7.1%) patients. The mean of symptoms severity of total scoring (24) was 15

    This study was conducted to determine the compartment 1 (C1) characteristics of alpacas (fistulated male, 7 ± 1.5 years old, 61 ± 5 kg BW) fed grass hay (GH) supplemented with amaranth (AM), quinoa (Q) and barley (B) grains. Alpacas were provided water ad libitum while housed in metabolism crates. The GH and GH plus treatments were fed at 0700 every day. Treatment periods were for 14 days in which GH or GH plus one of the grain treatments were randomly allocated. On day 14, volatile fatty acids (VFA), pH and ammonia nitrogen (NH3 -N) were determined at 1, 3, 6, 10, 14, 18 and 24 h post-feeding. C1 degradation of each feed component was also determined with the alpacas being fed GH only and the samples incubated for 0, 2, 4, 8, 14, 24, 48 and 72 h. Dry matter (DM), neutral detergent fibre (NDF) and crude protein (CP) were determined and were divided into three categories: a = immediately soluble; b = the non-soluble but degradable; and u = non-degradable/unavailable, potential extent of degradation (PE), degradation rate (c) and effective degradation (ED). C1 passage rate was determined using acid detergent insoluble ash as a marker and was calculated to be 5.5%∙h-1. Total DM intake was highest (p < 0.05) for B and resulted in a higher (p < 0.05) CP intake. GH and AM were different in mean pH (6.81 and 6.66, respectively). B NH3 -N was greater (p < 0.05) than the other treatments. Total VFA was greatest (p < 0.05) for AM, with the greatest composition differences being a shift form acetate percentage to butyrate. DM, NDF and CP degradation was different across the treatments, where PE and ED were higher (p < 0.05) for the grain treatments. The pseudo-grains AM and Q had similar C1 degradation characteristics to B. Journal of Animal Physiology and Animal Nutrition © 2015 Blackwell Verlag GmbH.

Foi possível identificar que os eventos extremos chuvosos ocorreram em maior número do que os eventos extremos secos. Na análise decadal verificou-se um aumento no número de eventos, quando comparada às décadas de 80, 90 e 2000. Vale ressaltar que o número de eventos da década de 2000 em relação à década de 80 (proporcionalmente foi o mais expressivo.This work presents a study of a rainfall variability mode that acts in southern Brazil and is called "Modo Sul" of precipitation. It was tried to show that the occurrences of maximum (and minimum of the "Modo Sul" of precipitation are related to the occurrence of extreme events in Rio Grande do Sul, as windstorm, flood, hail and drought. Using principal component analysis of daily filtered precipitation data for the 10-50 day band we found spatial pattern and temporal series that represent the maximum variance of certain variabilities, which are the modes of precipitation variability. Thus, it was possible to determine the mode of variability that appears well

    Full Text Available En la etapa de escolarización, el estudiantado vivencia procesos de alfabetización múltiples (New London Group, 2000, debido a que cada disciplina llevada al currículo escolar posee formas especiales de construir conocimientos, a través de ciertos recursos, procedimientos y visiones de mundo, y formas de comunicarlos. Dicha construcción de significados situada es, entonces, particular según la comunidad disciplinar del profesor o profesora y su especialidad (Unsworth, 2001. Desde el enfoque de la semiótica social, el objetivo del presente estudio, enmarcado en el Proyecto Fondecyt 1130684, busca identificar cuáles son los medios y los modos semióticos con los que se alfabetiza en clases de geografía, para reconocer su potencial epistémico a través de las herramientas de la gramática visual (Kress y van Leeuwen, 1996. Este trabajo se basa en dos estudios de casos y el corpus está constituido por el registro audiovisual de unidades curriculares. Se realizó un inventario multimodal de los medios y los modos para comunicar (Kress, 2010 utilizados por dos profesores en la enseñanza de la geografía en primaria y secundaria en escuelas públicas en Chile. Los resultados muestran que el profesorado alfabetiza a través de distintos medios y modos, los cuales, en su mayoría, son visuales, algunos de ellos más complejos de comprender debido a la densidad y cantidad de símbolos a interpretar. Como resultado, el conocimiento en esta disciplina requiere ser aprendido y mediado de forma multimodal.

  15. Percepções sobre adoção e aconselhamento de modos de vida saudáveis por profissionais de saúde

    Taís Rocha Figueira

    Full Text Available O artigo teve como objetivo comparar a percepção de profissionais da atenção primária sobre aconselhamento de modos de vida saudáveis antes e depois de uma intervenção educativa. Trata-se de estudo qualitativo desenvolvido com 22 profissionais de um centro de saúde de Belo Horizonte, Minas Gerais. A entrevista estruturada foi aplicada antes e depois da intervenção educativa, e os dados foram submetidos à análise de conteúdo. Os resultados mostram a dificuldade dos profissionais em adotar e aconselhar modos de vida saudáveis, com poucas mudanças em suas percepções após a intervenção educativa. As dificuldades estavam relacionadas a questões financeiras, culturais, de vida e de trabalho, bem como a concepções conservadoras. Predominou a prática curativista com responsabilização individual e o enfoque sobre hábitos alimentares e de atividade física. Identificou-se que, após a intervenção educativa, um número maior de profissionais estava sensibilizado quanto às atividades educativas coletivas e lúdicas e à importância da atuação multiprofissional. Assim, é vista a necessidade de continuidade da educação permanente dos profissionais de modo que permita a reflexão sobre concepções de saúde possíveis no contexto contemporâneo, favorecendo a produção do cuidado e da autonomia.

    Full Text Available A characteristic of the glass is its fragility and the scatter of the experimental mechanical strength due to the presence of defects that appear in the process of manufacturing or handling. Accordingly, investigations on this material were priorly conducted to improve the processes of manufacturing and to establish design methodologies based on probabilistic approaches. The influence of mode II of loading was traditionally ignored or considered as ratio of mode II. Recent studies have shown that when a shear-loaded crack becomes unstable a new compressive stress concentration field builds up in the notch formed between the original crack and the branch crack. This stress field affects the energy balance and also the beginning of crack extension. A procedure to design glass elements was developed jointly with CIDA of Cristalería Española, S.A. The aim of this work is to improve the model by the consideration of a mixed mode loading and its experimental contrast.

    Una de las características del vidrio es su fragilidad y la gran dispersión de sus valores de resistencia mecánica, motivado fundamentalmente por la presencia de defectos procedentes de su fabricación o de su manipulación. Como consecuencia, las investigaciones en este material se han dirigido preferentemente a la mejora de los procesos de fabricación y al establecimiento de metodologías de diseño basadas en modelos probabilísticos. Tradicionalmente, en el análisis de la rotura se ha despreciado la influencia del modo II o se ha representado como un porcentaje del modo I. Recientes estudios demuestran la aparición de un nuevo campo de tensiones de compresión cuando una fisura crece bajo una carga en modo II puro situado en el codo que se forma entre la fisura original y su ramificación. Este campo de compresión influye en el equilibrio energético y, en consecuencia, en la predicción de la rotura. En colaboración con el CIDA de Cristalería Española, S.A. se ha

    The recharge of the aquifer in the Crau plain (550 km2, Southern Rhone Valley, France) depends on the irrigation of 15000 ha of meadow using water withdrawn from the River Durance through a dense network of channels. Traditional irrigation practice, since the XVIth century, has consisted in flooding the grassland fields with a large amount of water, the excess being infiltrated toward the water table. Today, the Crau aquifer holds the main resource in water in the area (300 000 inhabitants) but changes in the agricultural practices and progressive replacement of the irrigated meadows by urbanized area threaten the sustainability of groundwater. The distributed modeling of irrigated meadows together with the modeling of groundwater has been undertaken for quantifying the contribution of the irrigation to the recharge of the aquifer and to investigate possible evolution of hay production, water drainage, evapotranspiration and water table under scenarios of climate and land-use changes. The model combines a crop model (STICS) that simulates hay production, evapotranspiration and water drainage, a multisimulation tool (MultiSimLib) that allows to run STICS over each agricultural field in the aquifer perimeter, a groundwater model MODFLOW to simulate the water table from recharge data (simulated drainage). Specific models were developed for simulating the spatial distribution of climate, including scenario of changes for the 2025 - 2035 time period, soil properties (influenced by irrigation), and agricultural practices (calendar and amount), in particular irrigation and hay cutting. This step was crucial for correctly simulating hay production level and amount of water used for irrigation. Model results were evaluated thanks to plot experiments and information from farmers (biomass production, downward water flow, quantity of irrigated water, cutting calendar...), a network of piezometers and remote sensing maps of evapotranspiration. Main results included: - the

    Full Text Available This study aimed to evaluate the correlations of intake, digestibility and performance with the ingestive behavior of lambs fed diets containing ammoniated buffel grass hay. Buffel grass hay was treated with four levels of urea (0, 18, 36 and 54 g/kg DM basis and eight repetitions. Thirty-two sheep with no defined breed and an average body weight of 17.7 ± 1.8 kg were distributed in a completely randomized design. It was observed positive correlations were found between the feeding time and the intake of dry matter (r = 0.3120, organic matter (r = 0.3242, neutral detergent fiber (r = 0.3800, total carbohydrates (r = 0.3343 and total digestible nutrients (r = 0.3233. Positive correlations (P < 0.05 were found among the rumination efficiencies, g of DM/h and g of NDF/h with nutrient intake variables, except for ether extract intake. Positive correlations were observed (P < 0.05 between both total weight gain (TWG and average daily gain (ADG and the rumination efficiency, g of DM/h (r = 0.3330 and g of NDF/h (r = 0.3304. The feeding and rumination efficiencies have a positive relationship with the total digestible nutrients. The correlation among intake, digestibility and performance variables with the ingestive behavior, it was important for the understanding of diet containing ammoniated buffel grass hay, in which the positive correlation of rumination efficiency with intake and weight gain explained the favorable effect on productive performance of feedlot sheep.

    The nutritive value and the conserved lucerne hay as a protein supplement in the diet of calves reared on the smallholder farms of Kenya was studied in relation to feed intake, growth rate and efficiency of feed utilization. Forty Friesian calves aged one week were allocate in a completely randomised design experiment to the following five dietary treatments: Napier Grass only (N) and supplemented with 33% lucerne (NL33), 50% lucerne (NL50), 67% lucerne (NL67) and 100% lucerne hay (L100) in the diet of calves. Results showed that increasing the level of lucerne supplementation in the ratio of dairy calves from 50 to 100% lucerne hay significantly (P <0.01) increased the crude protein content the mixed ration from 13.8 t o 16.88% CP which would meet the protein, requirement of the growing ruminants. The growth rate of calves increased linearly (P < 0.001) with the levels of lucerne supplements fro 50 to 100 % lucerne hay resulting in 0.02 kg gain more growth per day per kg additional feed supplement given. The cost of production per kg gain decreased with increase in the level of lucerne supplementation and cost of could further reduced by farmers growing lucerne on the smallholder farms for use in compounding home-made ration at the farm level. Result of these study further shows that lucerne as a leguminous forage has ability to fix Nitrogen in the soil which has significantly effect on soil fertility, increased crop yields and reduction in the cost of fertilisers. It is recommended that an acre of lucerne could yield five to seven tons of dry matter per year sufficient to rear a herd of 15 to 20 calves for a period of 1 year. This research has further shown that a pure stand of lucerne crop which is very deep rooted crop has a longevity of five to seven years in the same field and that pest and diseases are not of a serious problem to lucerne, thus making it excellent supplementary legume to the Napier grass in the diet of calves on smallholder farms of Kenya

    IL-33 polymorphisms influence the susceptibility to asthma. IL-33 indirectly induces Th2-immune responses via dendritic cell activation, being important for development of atopic diseases. Furthermore, IL-33 upregulates regulatory T cells (Tregs), which are critical for healthy immune homeostasis. This study investigates associations between IL-33 polymorphisms during the development of childhood atopic diseases and underlying mechanisms including immune regulation of Tregs. Genotyping of IL-33-polymorphisms (rs928413, rs1342326) was performed by MALDI-TOF-MS in 880 of 1133 PASTURE/EFRAIM children. In 4.5-year-old German PASTURE/EFRAIM children (n = 99), CD4 + CD25 high FOXP3 + Tregs were assessed by flow cytometry following 24-h incubation of PBMCs with PMA/ionomycin, LPS or without stimuli (U). SOCS3, IL1RL1, TLR4 mRNA expression and sST2 protein levels ex vivo were measured in PASTURE/EFRAIM children by real-time PCR or ELISA, respectively. Health outcomes (hay fever, asthma) were assessed by questionnaires at the age of 6 years. rs928413 and rs1342326 were positively associated with hay fever (OR = 1.77, 95%CI = 1.02-3.08; OR = 1.79, 95%CI = 1.04-3.11) and CD4 + CD25 high FOXP3 + Tregs (%) decreased in minor allele homozygotes/heterozygotes compared to major allele homozygotes (p(U) = 0.004; p(LPS) = 0.005; p(U) = 0.001; p(LPS) = 0.012). SOCS3 mRNA expression increased in minor allele homozygotes and heterozygotes compared with major allele homozygotes for both IL-33-polymorphisms (p(rs928413) = 0.032, p(rs1342326) = 0.019) and negatively correlated to Tregs. IL-33-polymorphisms rs928413 and rs1342326 may account for an increased risk of hay fever with the age of 6 years. Lower Tregs and increased SOCS3 in combined heterozygotes and minor allele homozygotes may be relevant for hay fever development, pointing towards dysbalanced immune regulation and insufficient control of allergic inflammation. © 2016 John Wiley & Sons A/S.

    Conclusions Had the Hayes principles been embedded within our approach to health IT, and in particular to medical record implementation, we might have avoided many of the costly mistakes with the UK national programme. However, these principles need application within the modern IT environment. Closeness to the patient must not be interpreted as physical but instead as a virtual patient-centred space; data will be secure within the cloud and we should dump the vault and infrastructure mentality. Health IT should be developed as an adaptive ecosystem.

The dehydration curve was determined in the whole plant for ten times until the baling. The zero time corresponded to the plant before cutting, which occurred at 11:00 and the other collections were carried out at 8:00, 10:00, 14:00, and 16:00. The experimental design was randomised blocks with two intensities of conditioning (high and low and ten sampling times, with five replications. The high and low intensities related to adjusting the deflector plate of the free iron fingers (8 and 18 cm. In order to determine gas exchanges during Tifton 85 bermudagrass dehydration, there were evaluations of mature leaves, which were placed in the upper middle third of each branch before the cutting, at every hour for 4 hours. A portable gas analyser was used by an infrared IRGA (6400xt. The analysed variables were photosynthesis (A, stomatal conductance (gs, internal CO2 concentration (Ci, transpiration (T, water use efficiency (WUE, and intrinsic water use efficiency (WUEi. In the second part of this study, the nutritional value of Tifton 85 hay was evaluated, so randomised blocks were designed in a split plot through time, with two treatments placed in the following plots: high and low intensity of cutting and five different time points as subplots: cutting (additional treatment, baling and after 30, 60, and 90 days of storage. Subsequently, fungi that were in green plants as well as hay were determined and samples were collected from the grass at the cutting period, during baling, and after 30, 60, and 90 days of storage. It was observed that Tifton 85 bermudagrass dehydration occurred within 49 hours, so this was considered the best time for drying hay. Gas exchanges were

    André Cordeiro dos Santos

    Full Text Available RESUMO: Tomando parte na discussão que há no campo da teoria do jornalismo sobre a objetividade e a subjetividade, e falando do lugar da linguagem, neste trabalho, propomos que os modos de apropriação do discurso de outrem podem ser um meio à resolução desse impasse, pois levantamos a hipótese de que eles evidenciam posicionamentos sócio-ideológicos do sujeito-jornalista em relação ao objeto de enunciação. Para tanto, partimos da concepção de linguagem do chamado Círculo de Bakhtin e tomamos notícias dos dois jornais mais lidos do estado de Pernambuco, Diário de Pernambuco e Jornal do Commercio, respectivamente, sobre Eduardo Campos, candidato à presidência do Brasil em 2014. As análises feitas mostraram que os modos de apropriação do discurso de outrem podem servir a efeitos de sentidos diversos entre si e que, quando da apropriação do discurso de outrem, o sujeito-jornalista não cede lugar ao outro, mas, sim, fala junto com ele, evidenciando posicionamentos ideológicos por meio das notícias.

La información respecto a las prácticas de producción agrícola, entre ellas, el manejo integrado de plagas, y la toxicidad de los pesticidas constituyeron las variables dependientes. La participación en organizaciones, y la cohesión social, entre otros aspectos del capital social fueron tratados en el análisis como variables independientes. Los hallazgos sugieren que la información para la salud es transmitida por las estructuras del capital social en dependencia de su valor de uso en el marco del modo de producción agrícola.

    Full Text Available The effects of replacing Tifton hay with castor bean hulls (0, 33, 66 and 100% on the leg tissue composition, chemical composition, physicochemical parameters and sensorial traits of sheep meat were studied. A total of 28 non-castrated sheep averaging seven months in age with an average initial weight of 19.5±4.3 kg were assigned to a randomized block design with four treatments and seven replicates and were slaughtered after 70 days of confinement. At slaughter, body weight and leg, muscle and bone weights decreased linearly, whereas the muscle-to-bone ratio increased linearly according to the treatments. There was a quadratic effect on yellow intensity (maximum of 8.05 with replacement of 54.5% and the percentage of cooking losses (minimum of 33.8% with replacement of 45.17%. The treatment employed did not affect either the chemical composition or sensorial traits of the lamb meat. Although replacing Tifton hay with castor bean hulls alters the tissue composition of the leg as well as some physicochemical parameters of the meat, the sensory analysis indicated good acceptability of the meat, regardless of the inclusion of this byproduct.

    Contaminated hay harvested in the south-east of France in June 1986 was fed to lactating and non-lactating ewes for 50-60 days. The mean transfer coefficients observed were 0.075 days litre -1 to milk and 0.11 days kg -1 to meat. Adding vermiculite to feed pellets decreased the transfer coefficients by a factor of 2.5 to both milk and meat if given at 30 g day -1 ; a factor of 8 difference was reached using 60 g day -1 added vermiculite or 2 g day -1 ammonium ferricyanoferrate (AFCF). No adverse effects on intake rates, animal weight or milk production were observed during the administration period (90-100 days, 50-60 days during the oral contamination and 40 days during the depletion period), whatever the treatment. Three lactating goats were fed the same contaminated hay, but chopped and mixed with powdered maize, for 15 days. The mean milk transfer coefficient was lower than that for ewes at 0.032 days litre -1 . (author)

  20. Datura contamination of hay as the suspected cause of an extensive outbreak of impaction colic in horses : clinical communication

    Full Text Available atura poisoning of horses is extensively reviewed. An outbreak of intractable impaction colic affecting 18 of 83 horses was stopped by withdrawing dried tef hay contaminated with young Datura plants. The dried, botanically identified Datura stramonium and D. ferox contained respectively 0.15 % mass/mass (m/m hyoscyamine as well as 0.16 % m/m hyoscine (scopolamine and only hyoscine at a concentration of 0.11 % m/m. Immature, unidentifiable plants resembling D. stramonium, contained 0.14 % m/m and 0.12 % m/m of the 2 respective tropane alkaloids. The outbreak was characterised by protracted and repeated colic attacks due to impaction of the large colon and/or caecum without any other anti-muscarinic signs. Comparative analyses of single specimens of dried seed of the 2 species collected from both fertilised and waste areas revealed that young South African Datura spp. had levels of tropane alkaloids comparable to those in the well-known toxic seed and were, consequently, equally toxic. The inherent danger of tef hay being contaminated with Datura is emphasised. To our knowledge this is the 1st field case of poisoning in horses ascribed to the vegetative parts of Datura spp.

    2006-06-01

    Full Text Available Two out of a group of 23 mares exposed to tef hay contaminated with Datura ferox (and possibly D. stramonium developed colic. The 1st animal was unresponsive to conservative treatment, underwent surgery for severe intestinal atony and had to be euthanased. The 2nd was less seriously affected, responded well to analgesics and made an uneventful recovery. This horse exhibited marked mydriasis on the first 2 days of being poisoned and showed protracted, milder mydriasis for a further 7 days. Scopolamine was chemically confirmed in urine from this horse for 3 days following the colic attack, while atropine could just be detected for 2 days. Scopolamine was also the main tropane alkaloid found in the contaminating plant material, confirming that this had most probably been a case of D. ferox poisoning. Although Datura intoxication of horses from contaminated hay was suspected previously, this is the 1st case where the intoxication could be confirmed by urine analysis for tropane alkaloids. Extraction and detection methods for atropine and scopolamine in urine are described employing enzymatic hydrolysis followed by liquid-liquid extraction and liquid chromatography tandem mass spectrometry (LC/MS/MS.

    Full Text Available Six mature male Kacang goats were involved in an experiment arranged following a duplicate 3 x 3 Latin Square Design. The objectives of this experiment was to study the effect of supplementation of dried fish as compared to fishmeal on intake, digestion, rumen environment and nitrogen used by the local meat type Kacang goats maintained on urea-treated low quality grass hay. The treatments were G: goats were fed with ad libitum access of urea treated grass hay and 100 g/d putak, SDF: G plus 18.4 g sun dried fish, and FM: G plus 19.7 g/d fishmeal. The supplement in SDF and FM were at equal CP level. Intake of urea treated grass hay tended to increase (P=0.08 with supplementation. Dry matter digestibility particularly that of CP was improved by supplementation. Rumen environment was slightly modified by supplementation. Rumen pH was reduced while ammonia concentration was increased. Rumen degradation of the treated grass hay did not differ when incubated in the rumen of goats with different diets. Nitrogen balance was significantly improved (P<0.05 by fishmeal supplementation. In all parameters measured in this experiment, the incremental effects did not differ between fishmeal type. This indicate that there is no further advantage of preparing fishmeal other than sun-drying in improving the utilisation of low quality urea-treated grass hay.

    Twenty-eight indigenous ewe lambs (6 months of age and 14.4 kg body weight (BW)) were used to evaluate the effect of feeding Sporobolus grass hay (SGH) as the only source of forage on growth, and feed and water intakes. The ewe lambs were randomly and equally allocated to two treatment groups (14 lambs/group). The ewe lambs in group 1 (treatment 1) received SGH, while lambs in group 2 (treatment 2) received Rhodes grass hay (RGH) as the only source of forage. Water was available at all times for both treatment groups. Sporobolus grass was irrigated with brackish water of high salt content (20,000 ppm) and grown in saline desert lands (sabkha) in the United Arab Emirates. The average daily dry matter intake was significantly (P  .05) between the two groups at all stages. From these data, we conclude that SGH can replace Rhodes hay in sheep diet without significant effect on sheep performance.

    electrica. El controlador debe ser robusto ante variaciones parametricas que se pueden presentar por incertidumbre en los modelos, envejecimiento de los componentes de los generadores y algunas otras causas fisicas. Otro factor a considerar es que los modelos de sistemas multimaquinas son de alto orden, por lo cual se dificulta el diseno de controladores y la implementacion de los mismos en el sistema. Entonces, es conveniente disenar controles descentralizados que puede facilitar la tarea de diseno e implementacion de los mismos. Este trabajo propone tres nuevas tecnicas robustas para sistemas no lineales. La primera esta basada en la metodologia de control por bloques y modos deslizantes integrales; esta combinacion permite aplicar modos deslizantes integrales en cada bloque del sistema, rechazando las perturbaciones existentes en cada bloque. La segunda tecnica propone el diseno de una variedad deslizante a partir del modelo hamiltoniano de sistemas no lineales, misma que sera utilizada para un control por modos deslizantes. La tercera tecnica propone la aplicacion de modos deslizantes en cada bloque de un sistema no lineal controlable por bloques, mediante la utilizacion de la funcion de Lyapunov de ese bloque. Posteriormente se disenan cuatro esquemas de control descentralizado para sistemas electricos de potencia multimaquinas. Los cuatro esquemas propuestos son robustos ante las perturbaciones mencionadas. Ademas, estos controladores se pueden implementar en cualquier sistema electrico de potencia con n generadores, m lineas y k cargas.

    The Mod-O 100 kW Experimental Wind Turbine was designed and fabricated by NASA, as part of the Federal Wind Energy Program, to assess technology requirements and engineering problems of large wind turbines. The machine became operational in October 1975 and has demonstrated successful operation in all of its design modes. During the course of its operations the machine has generated a wealth of experimental data and has served as a prototype developmental test bed for the Mod-OA operational wind turbines which are currently used on utility networks. This paper describes the mechanical and control systems as they evolved in operational tests and describes some of the experience with various systems in the downwind rotor configuration.

    2010-01-01

    There has been much criticism of the NHS national programme for information technology (IT); it has been an expensive programme and some elements appear to have achieved little. The Hayes report was written as an independent review of health and social care IT in England. To identify key principles for health IT implementation which may have relevance beyond the critique of NHS IT. We elicit ten principles from the Hayes report, which if followed may result in more effective IT implementation in health care. They divide into patient-centred, subsidiarity and strategic principles. The patient-centred principles are: 1) the patient must be at the centre of all information systems; 2) the provision of patient-level operational data should form the foundation - avoid the dataset mentality; 3) store health data as close to the patient as possible; 4) enable the patient to take a more active role with their health data within a trusted doctor-patient relationship. The subsidiarity principles set out to balance the local and health-system-wide needs: 5) standardise centrally - patients must be able to benefit from interoperability; 6) provide a standard procurement package and an approved process that ensures safety standards and provision of interoperable systems; 7) authorise a range of local suppliers so that health providers can select the system best meeting local needs; 8) allow local migration from legacy systems, as and when improved functionality for patients is available. And finally the strategic principles: 9) evaluate health IT systems in terms of measureable benefits to patients; 10) strategic planning of systems should reflect strategic goals for the health of patients/the population. Had the Hayes principles been embedded within our approach to health IT, and in particular to medical record implementation, we might have avoided many of the costly mistakes with the UK national programme. However, these principles need application within the modern IT

    Full Text Available A fractografia consiste no estudo detalhado da morfologia da superfície de fratura de materiais. Para isto, a técnica de microscopia eletrônica de varredura (MEV é usualmente utilizada para determinar a causa de falha e a relação do modo de falha com a microestrutura do material em análise. Essas informações permitem estabelecer analogia entre estrutura, propriedade e processamento do material com a iniciação e a propagação da falha. Neste estudo, a análise fractográfica é utilizada para investigar os aspectos que caracterizaram a falha por delaminação em Modo II de laminados poliméricos de uso estrutural. Para isto, espécimes com um inserto de Teflon® introduzido no plano médio de uma das extremidades do laminado (End-Notched foram submetidos ao ensaio de carregamento em flexão em quatro pontos. Os espécimes foram preparados a partir de um laminado fabricado em autoclave, com camadas (0º, 90º de material pré-impregnado de tecido bidirecional em estilo plain weave de fibras de carbono IM7/resina epóxi M21. Os resultados da análise mostram que a superfície de fratura é muito irregular, com a visualização de fibras e impressões de fibras na matriz. Aspectos fractográficos de cúspides e formatos de concha, originados durante o cisalhamento da matriz polimérica, são também observados.

    Full Text Available Increasing the efficiency of utilization of fresh and preserved forage is a key target for ruminant science. Vitamin E is often used as additive to improve product quality but its impact of the rumen function is unknown. This study investigated the successional microbial colonization of ryegrass (GRA vs. ryegrass hay (HAY in presence of zero or 50 IU/d supplementary vitamin E, using a rumen simulation technique. A holistic approach was used to link the dynamics of feed degradation with the structure of the liquid-associated (LAB and solid-associated bacteria (SAB. Results showed that forage colonization by SAB was a tri-phasic process highly affected by the forage conservation method: Early colonization (0–2 h after feeding by rumen microbes was 2× faster for GRA than HAY diets and dominated by Lactobacillus and Prevotella which promoted increased levels of lactate (+56% and ammonia (+18%. HAY diets had lower DM degradation (-72% during this interval being Streptococcus particularly abundant. During secondary colonization (4–8 h the SAB community increased in size and decreased in diversity as the secondary colonizers took over (Pseudobutyrivibrio promoting the biggest differences in the metabolomics profile between diets. Secondary colonization was 3× slower for HAY vs. GRA diets, but this delay was compensated by a greater bacterial diversity (+197 OTUs and network complexity resulting in similar feed degradations. Tertiary colonization (>8 h consisted of a slowdown in the colonization process and simplification of the bacterial network. This slowdown was less evident for HAY diets which had higher levels of tertiary colonizers (Butyrivibrio and Ruminococcus and may explain the higher DM degradation (+52% during this interval. The LAB community was particularly active during the early fermentation of GRA and during the late fermentation for HAY diets indicating that the availability of nutrients in the liquid phase reflects the dynamics

    Full Text Available The effects on the digestive process and the productive performances of dairy cows fed diets containing alfalfa hay from  different germplasms and maturity were assessed in the present study. Three different lots of first-cut alfalfa hay were  used in the study: the improved variety “Boreal”, harvested at two consecutive maturity stages (early flowering and full  flowering and the ecotype “Vogherese”, at full flowering. Cutting the plant at an earlier stage of maturity improved hay  quality in comparison with the more mature forages (crude protein: 21.4 vs 16.5% DM; P  DM; P  er lignin content for the latter (8.6 vs 8.2% DM; P  tating cows were formulated using an equal amount of corn silage and the maximum inclusion of one of the tested hays  as forage base. The better quality of the early cut hay made it possible to increase its inclusion in the diet up to 44% of  total dietary DM, while the two more mature hays covered only 36% of total DM of the respective diets. According to a  3 x 3 Latin square design, the diets were fed to 3 Italian Brown cows (initial average days in milk 121 ± 24 and milk  yield 20 kg ± 1.3 fitted with ruminal cannula in 3 consecutive periods of 28 d each. Alfalfa stage of maturity and  germplasm did not affect dietary DM intake (average 16 kg/d. Degradability parameters of dietary DM, calculated by in  situ nylon bags technique, showed similar kinetics of rumen disappearance for all diets. No differences were noticed in  the ruminal rate of passage of the solid phase among diets, while the liquid phase showed a slower rate of passage for  the early flowering hay diet. Consistent with the degradation process, the stage of maturity or the alfalfa germplasm did  not affect the rumen fluid data or the in vivo digestibility coefficients of the diets. Milk yield did not show any change due  to either alfalfa maturity or cultivar, while milk protein was lowered when cows received the early cut hay

  1. Lead deposit on vegetation growing along highways traveled by automobiles. Milk cow feeding experiments with hay contaminated with lead

    Bovay, E

    1971-03-01

    Measurements conducted in Switzerland from 1967 through 1970 revealed that vegetation growing along highways contained lead in concentrations in excess of 100 ppm. Although the amounts of lead in vegetation rapidly decrease with distance from the highway, lead can be detected up to a distance of about 100 M. The rate and extent of dispersion of lead particles depended on seasonal orographic and/or meteorological conditions. Lead retention by different plant organs is governed by their nature and composition. Plants with large hairy leaves or leaves with a rough surface accumulate much more lead than plants with smooth leaves. From 35-65% of the plant tissue lead content can be removed by thorough washing, an indication that the contamination consists for the most part in a surface deposit. But plant roots growing in lead-contaminated soil absorb the element, even if present in a relatively insoluble form. In spite of these observations, no symptoms of plant disease or a decrease in crop yield has been noted. High tightly growing hedges of perennials (pine or fir) markedly reduce the dispersion of exhaust gases. Feeding trials with mild cows involving hay harvested along highways demonstrated that a high percentage of the lead ingested with the fodder was eliminated. Some organs like bones, kidneys, and the liver accumulated large quantities of lead (up to 21-fold quantities). After four weeks on the contaminated hay, the lead content in milk quadrupled. The cows ingested 1300 mg lead daily with contaminated fodder containing 99 ppm Pb. Toxic symptoms in cattle and horses do not appear until an ingestion level of about 2200 mg Pb/day is reached. 36 references.

    An experiment was conducted to evaluate the performance of dairy goats supplemented with fodder based diets. Six lactating does of Saanen, Toggenburg and Saanen X Toggenburg breed types weighing 46 + or - 7.1 at late stage of lactation were allocated to three dietary treatments in a double 3*3 Latin square design to examine the value of leucaena and gliricidia forages as nitrogen sources in supplementing Rhodes grass hay. Three supplements: Leucaena-based (L), gliricidia-based (G) or commercial concentrate (C) were used. Voluntary feed intake, milk yield, milk composition and live weight changes were measured. Total dry matter intake (DMI) was significantly higher in group G than C (1385 vs 1331 g day -1 ). Hay DMI was higher in G (835 g d -1 than L or C (789, 782 g day -1 , respectively). Diets had no effect on milk yield, crude protein or butterfat content. Total solid was higher in L than C while that of G was intermediate (15.7, 14.7, 13.7%). Weight changes were least affected although resulted in positive gain (11 g day -1 ) while the others lost (-13,-19 g day -, for L and C respectively). In the digestibility trial 6 female goats weighing 22.3 kg (sd 1.1), were allocated to the three treatments in a completely randomised block design where each goat received a different supplement in each of two periods. Thee were no differences in nutrient digestibility except for DM, which was in C compared to the other treatments (615, 622, 720 g-kg for L, G and C, respectively). It si concluded that fodder based supplement compared well with the commercial concentrate in supporting milk yield and body weight gain of dairy goats. Therefore, locally available tree fodders can be incorporated in supplement diets and utilized without any detrimental effects to substitute the expensive concentrates to improve the performance of dairy goats

    The experiment was conducted at Sekota District using 36 intact yearling males of pure Abergelle breed and Abergelle crossbred goats (50%) with a mean live weight of 18.92 ± 0.72 kg (mean ± SE). The objective of the experiment was to evaluate the effect of different levels of concentrate mixture supplementation on feed intake, live weight gain, and economic gain of the breeds. Goats were blocked based on initial body weight and were randomly assigned to the dietary treatments. The experimental design was a 2 × 3 factorial in RCBD (randomized complete block design). The treatments included ad libitum feeding of local grass hay and supplementation with three levels (184, 368, and 552 g/day) of concentrate mixture. The experiment consisted of 90 days of feeding. Daily, total dry matter and CP (crude protein) intakes were affected by diet and genotype (P < 0.01). Significant decrease (P < 0.001) in hay intake was observed as the level of the supplement increased. Besides, substitution rate increased with increasing levels of supplementation. Average daily body weight gains were significantly impacted only by diet. Animals fed on 184 significantly lower weights, while nonsignificant difference was observed in live weight gain between 368 and 552 supplemented group. Supplementation of 368 concentrate mix significantly improved (P < 0.05) feed intake, daily weight gain, and feed conversion efficiency. Supplementation of 368 g/day had showed significantly higher net return for both goat breeds. However, the Abergelle breed was significantly better in net profit and sensitivity than the crossbreed. Both genotypes performed better with the diet containing 368 g/day than that with 184 and 552 g/day of concentrate supplementation.

    The rumen microbiota enable important metabolic functions to the host cattle. Feeding of starch-rich concentrate feedstuffs to cattle has been demonstrated to increase the risk of metabolic disorders and to significantly alter the rumen microbiome. Thus, alternative feeding strategies like the use of high-quality hay, rich in sugars, as an alternative energy source need to be explored. The aim of this study was to investigate changes in rumen microbial abundances in the liquid and solid-associated fraction of cattle fed two hay qualities differing in sugar content with graded amounts of starchy concentrate feeds using Illumina MiSeq sequencing and quantitative polymerase chain reaction. Operational taxonomic units clustered separately between the liquid and the solid-associated fraction. Phyla in the liquid fraction were identified as mainly Firmicutes, Proteobacteria and Bacteroidetes, whereas main phyla of the fibre-associated fraction were Bacteroidetes, Fibrobacteres and Firmicutes. Significant alterations in the rumen bacterial communities at all taxonomic levels as a result of changing the hay quality and concentrate proportions were observed. Several intermicrobial correlations were found. Genera Ruminobacter and Fibrobacter were significantly suppressed by feeding sugar-rich hay, whereas others such as Selenomonas and Prevotella proliferated. This study extends the knowledge about diet-induced changes in ruminal microbiome of cattle. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

    In newborn dairy calves, it has been demonstrated that supranutritional maternal and colostral Se supplementation using Se yeast or sodium selenite, respectively, improves passive transfer of IgG. In beef cattle, agronomic biofortification with Se is a more practical alternative for Se supplementation, whereby the Se concentration of hay is increased through the use of Se-containing fertilizer amendments. It has been previously demonstrated that agronomic Se biofortification is an effective strategy to improve immunity and performance in Se-replete weaned beef calves. The objective of this experiment was to determine the effects of feeding beef cows Se-enriched alfalfa () hay during the last 8 to 12 wk of gestation on passive transfer of antibodies to calves. At 10 wk ± 16 d before calving, 45 cows were assigned to 1 of 3 treatment groups with 3 pens (5 cows/pen) per treatment: Control cows were fed non-Se-fortified alfalfa hay plus a mineral supplement containing 120 mg/kg Se from sodium selenite, Med-Se cows were fed alfalfa hay fertilized with 45.0 g Se/ha as sodium selenate, and High-Se cows were fed alfalfa hay fertilized with 89.9 g Se/ha as sodium selenate; both the Med-Se and the High-Se groups received mineral supplement without added Se. Colostrum and whole blood (WB) were collected from cows at calving, and WB was collected from calves within 2 h of calving and at 12, 24, 36, and 48 h of age. Concentrations of IgG1 and J-5 antibody in cow colostrum and calf serum were quantified using ELISA procedures. Selenium concentrations linearly increased in WB ( cows and in WB of newborn calves ( cows fed Se-biofortified alfalfa hay, but J-5 antibody ( = 0.43) concentrations were not. Calf serum IgG1 ( = 0.43) and J-5 antibody ( = 0.44) concentrations during the first 48 h of age were not affected by prior Se treatment of cows. These data suggest that feeding Se-biofortified alfalfa hay promotes the accumulation of Se and antibodies in colostrum but does not

    This study investigated the effect of replacing alfalfa hay by subabul leaf meal (SLM) on digestion, fermentation parameters and rumen bacteria and fungi activity of Najdi goats. Six Najdi goats (150 ± 15 days of age and initial body weight of 35 ± 1.1 kg) were randomly assigned to one of two dietary treatments in a balanced completely randomized design (three goats per treatment) for 56 days. Experimental treatments included alfalfa hay as control group and diet containing SLM (SLM replacing alfalfa hay at 50% level). Bacterial and fungi activity and rumen fermentation parameters of animals fed experimental diets were determined. Dry matter disappearance (DMD) was unaffected by replacing SLM with alfalfa hay for both rumen bacteria and fungi in different incubation times, except for 48 h of incubation in specific culture medium of mixed rumen bacteria, which decreased for SLM group (P > 0.05). NDF disappearance (NDFD) and ADF disappearance (ADFD) after 24 and 48 h of incubation in specific culture medium of mixed rumen bacteria was not affected by experimental diets (P > 0.05). However, 72 h after incubation, NDFD in SLM treatment decreased (P > 0.05). Gas production parameters of rumen bacteria were similar for both experimental diets, but partitioning factor (PF), efficiency microbial biomass production (EMBP), microbial protein production (MP), and organic matter truly digested (OMTD) decreased (p alfalfa hay by SLM had no major effect on rumen microorganisms' activity of Najdi goats, so it may be used as an alternative for alfalfa (at 50% level) in susceptible areas.

    The experiment was conducted to determine the supplementary feeding value of ground Prosopis juliflora pod (Pjp) and cottonseed meal (CSM) and their mixtures on feed intake, body weight gain and carcass parameters of Afar sheep fed a basal diet of pasture hay. Twenty-five yearling fat-tailed Afar rams with mean initial live weight 17.24 ± 1.76 kg (mean ± SD) were used in a randomized complete block design. Animals were blocked on their initial body weight. The experiment was conducted for 12 weeks and carcass evaluation followed. Treatments were hay alone ad libitum (T 1) or with 300 g CSM (T 2), 300 g Pjp (T 5), 2:1 ratio (T 3) and 1:2 ratio of CSM : Pjp (T 4). The CP contents of the hay, CSM and Pjp were 10.5, 44.5 and 16.7 %, respectively. Hay DM intake was higher (P < 0.05) for non-supplemented and total DM intake was lower in non-supplemented. Average daily weight gain (ADG) was lower (P < 0.05) for T 1 compared to all supplemented treatments except T 5. Hot carcass weight and rib-eye muscle area also followed the same trend like that of ADG. Compared with feeding hay alone, supplementing with CSM or a mixture of CSM and Pjp appeared to be a better feeding strategy, biologically, for yearling Afar rams.

    Test boring at 21 places and core sampling were conducted during September-November 1998 along the ridge to the west of Hay Gulch and in the direction crossing the northwest of the drainage canal and National King Coal Mine (NKC coal mine). It was found that A layer which NKC coal mine is now drilling is the upper part of A coal seam where the seam bifurcates. The boundary to the west of the thick A coal seam is not clear, and there is a possibility that more reserve from the thick coal seam and single seam exists toward Cherry Creek. In the existing coal drilling area, the lower A seam existing under the upper A seam becomes thin rapidly, and the seam thickness becomes less than 1 foot. The average thickness of thick coal seams is 9.9 feet, and the area is 780 acres along the ridge. The upper A coal seam except the above is 5.5 feet in average seam thickness and 910 acres in area. The reserve is 23 million tons. As to the quality of thick coal seam, the average heating value is 7,089 kcal/kg, sulfur content 0.68%, and ash content 7.50%. As coal drilling conditions, the same level as or higher than those of NKC coal mine is expected. (NEDO)

    The aim of this work was to characterize the energy consumption related to the introduction, development, hay processing and storage of Cynodon dactylon (L.) Pers allied to the analysis of the energetic efficiency. The data used in this project were collected from EMBRAPA Gado de Leite, localized in Coronel Pacheco, Minas Gerais, Brazil. The data were obtained from a seven year period of an intensive system of milk production. Energetic coefficients were used to generate the survey and several matrix components obtained from pertinent literature. The direct energy, related to the inputs, showed more efficient participation on the energetic matrix than the indirect energy and the percentages were 94.64 and 5.31, respectively. Farm tractor was the main indirect energy consumer, which is responsible for turning on all the equipment, followed by the irrigation system. The energetic efficiency presented by the whole system was 4.2, being considered positive and demonstrating that the agriculture ecosystem is sustainable. Most of the direct energy employed in this system was oil derived on fuel form. There was, however, a great consume of another oil derived energy such as fertilizer, but mainly on the nitrogen form (28.89% of the total employed energy). (author)

    Sparing zones from mowing has been proposed, and applied, to improve local conditions for survival and reproduction of insects in hay meadows. However, little is known about the efficiency of refuge zones and the consequences for local populations. We studied population densities of butterflies before and after mowing in the refuge zone of 15 meadows in 2009 and 2011. We also studied the behaviour of the meadow brown (Maniola jurtina) comparing nectar use, interactions and flights in the refuge zone before and after mowing. Densities of grassland butterflies in this zone doubled on average after mowing. The density of females of M. jurtina increased on average fourfold, while males showed a more modest increase. In line with the idea of increased scramble competition in the refuge zone after mowing, M. jurtina increased the time spent on nectar feeding, the preferred nectar source was visited more frequently, and females made more use of non-preferred nectar sources. Maniola jurtina did not interact more with conspecifics after mowing, but interactions lasted longer. Flight tracks did not change in linearity, but were faster and shorter after mowing. After mowing, only a part of the local grassland butterflies moved to the uncut refuge zone. The resulting concentration effect alters the time allocated to different activities, nectar use and movements. These aspects have been largely ignored for agri-environmental schemes and grassland management in nature reserves and raise questions about optimal quantities and quality of uncut refuge sites for efficient conservation of grassland arthropods in agricultural landscapes.

Apesar da importância desse Programa para a fixação do homem ao campo, neste artigo procura-se chamar a atenção para a necessidade de adequação da tipologia de casa do PNHR ao modo de morar na área rural. A pesquisa fundamentou-se na análise da habitação rural em Minas Gerais, mais especificamente na região da Zona da Mata, bem como na análise da legislação que rege o PNHR, como leis, portarias e decretos. Os resultados apontaram que as especificações técnicas mínimas estabelecidas pelo Ministério das Cidades para o PNHR desconsideram o modo de vida rural e os hábitos dos moradores. Embora haja o cuidado de não estabelecer áreas mínimas para os compartimentos, a fixação da área útil total em 36m2 e o dimensionamento induzido a partir do tamanho e descrição do mobiliário mínimo conduzem à formatação de um programa de necessidades muito semelhante ao da tipologia de casa adotado pela versão urbana do Programa Minha Casa Minha Vida.  Palavras-Chave: política habitacional, habitação rural, Programa Minha Casa Minha Vida.   Abstract The National Rural Housing Program (PNHR is the rural part of the “Minha Casa, Minha Vida” Program and aims to reduce rural housing deficit through the renovation or construction of new housing.

    Full Text Available RESUMO: Neste trabalho é feita uma avaliação dos modos de falha de compósitos de matriz polimérica reforçados por fibras de vidro, carbono ou aramida, submetidos a carregamento dinâmico. Os compósitos unidirecionais analisados foram fabricados por prensagem e cura à vácuo de lâminas de pré-impregnados. A energia total absorvida na fratura mostrou uma correlação inversamente proporcional ao módulo elástico das fibras usadas como reforço. Os compósitos com fibras de carbono falharam de um modo frágil. Para estes compósitos o comportamento ao impacto pode ser modelado usando-se uma análise puramente elástica. Para os compósitos com fibras de vidro a falha foi controlada por um mecanismo misto de cisalhamento ao longo da interface fibra-matriz e tensão normal trativa atuando perpendicularmente às fibras. O modelo elástico empregado para simular o comportamento ao impacto subestima a energia absorvida por estes compósitos, porém, a diferença entre os valores experimentais e os calculados não ultrapassou 20 %. A falha dos compósitos com fibras aramidas foi atribuída, principalmente, ao componente de tensão trativa atuando perpendicularmente às fibras. Nestes compósitos foi observado arrancamento superficial nas fibras aramidas e o comportamento ao impacto não obedece o modelo elástico empregado.ABSTRACT: In this work an evaluation of the fracture mode of fiber reinforced resin matrix composites submitted to three point bending dynamic impact testing was undertaken. The unidirectional glass, carbon and aramid fiber-epoxy matrix composites used were fabricated by vacuum bagging prepreg laminas.

A FMEA é uma metodologia que vem sendo amplamente utilizada no processo produtivo das organizações, tanto em projetos e produtos, por apresentar imensas possibilidades na potencialização da qualidade e na prevenção de falhas no processo. Este artigo demonstrou, sem a pretensão de esgotar a abordagem sobre o tema, que a qualidade se caracteriza de extrema importância para as organizações na atualidade. No entanto, como observado, esta ferramenta requer um bom nível de preparo e de planejamento por parte de seus executores, tanto do responsável direto, quanto da equipe executante, pois como qualquer metodologia o FMEA apresenta algumas limitações. Com a aplicação da FMEA em uma indústria de autopeças, verificou-se que o trabalho bem coordenado e planejado desempenha um papel importante na minimização de riscos, e consequentemente de custos, potencializando o processo de tomada de decisão em nível de produção. Dessa maneira, por meio do estudo de caso, pôde-se comprovar a eficácia da metodologia FMEA, que inclusive, foi ampliada para outros processos da empresa.

    Full Text Available O objetivo deste trabalho foi determinar o modo de reprodução e as condições para testes de viabilidade in vitro de pólen de três espécies de jabuticabeira (Plinia cauliflora, P. trunciflora e P. jaboticaba. Avaliaram-se a frutificação efetiva em ramos ensacados e não ensacados, e aspectos da morfologia floral. A viabilidade de pólen foi avaliada em meio de cultura com e sem ácido bórico, com pólen coletado em diferentes períodos após antese. A germinação de pólen de seis genótipos foi quantificada antes e após armazenamento. P. trunciflora e P. jaboticaba são autocompatíveis, porém os polinizadores aumentam a frutificação. A espécie Plinia cauliflora necessita de agentes polinizadores para frutificar, pois apresenta flores com maior distância estigma-anteras que as outras duas espécies, o que impede a autofecundação passiva. A adição de ácido bórico no meio de cultura aumenta a germinação in vitro de pólen de jabuticabeira. A viabilidade do pólen é máxima após seis horas da antese. É possível a conservação do pólen por até 90 dias em congelador (-18ºC, desde que apresente alta germinação inicial (maior que 80%.

    Nutritional value of Kallar grass (Leptochloa fusca Linn) hay (whole plant), a salt-tolerant plant, was estimated by determinning its composition (ash, crude protein CP, crude fibre CF, ether extract EE, neutral-detergent fiber NDF, acid-detergent fiber ADF, acid-detergent lignin ADL); and the in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), net energy of lactation (NEL) and gross energy (GE). Moreover, dry matter, energy and protein yields per hectar were also estimated. The effects of feeding Kallar grass hay to pregnant Awassi ewes on reproductive performance, serum progesterone changes using radioimmunoassay, and on birth and weaning weights of lambs born were also determined. Experimental ewes received daily 300 g of Kallar grass hay in addition to lentil straw and concentrates to cover their nutritional requirements. The results indicated that the nutritive components of Kallar grass were (g kg -1 dry matter): ash 96, CP 93, CF 290, EE 21, NDF 755, ADF 416 and ADL 94. IVOMD was 49.3%, and energy values (MJ kg -1 dry matter) were: GE 26.88, ME 6.41 and NEL 3.02. Dry matter and crude protein yields of Kallar grass hay were 7875 and 732 kg ha -1 , respectively, and the energy produced (MJ ha -1 ) was: GE 211680, ME 50479 and NEL 23783. Kallar grass had no effects on the reproductive performance of pregnant Awassi ewes duration, of pregnancy (150.1 ± 2.2 days), progesterone patterns, birth (4.7±1.0 kg) or on weaning weights (22.7 ± ≤ 5.5 kg) of lambs.

    To determine whether feeding a commercial anionic dietary supplement as a urinary acidifier to male goats may be useful for management of urolithiasis. 8 adult sexually intact male Toggenburg, Saanen, and Nubian goats. Goats were randomly assigned by age-, breed-, and weight-matched pairs to an oat or grass hay diet that was fed for 12 days. On days 13 to 14 (early sample collection time before supplementation), measurements were made of blood and urine sodium, potassium, calcium, magnesium, chloride, phosphorus, and sulfur concentrations; blood and urine pH; urine production; and water consumption. During the next 28 days, the anionic dietary supplement was added to the oat and grass hay diets to achieve a dietary cation-anion difference of 0 mEq/100g of dry matter. Blood and urine samples were analyzed during dietary supplementation on days 12 to 13 (middle sample collection time) and 27 to 28 (late sample collection time). Blood bicarbonate, pH, and urine pH of goats fed grass hay and goats fed oat hay were significantly decreased during the middle and late sample collection times, compared with the early sample collection time. Water consumption and urine production in all goats increased significantly during the late sample collection time, compared with the early sample collection time. The anionic dietary supplement used in our study increases urine volume, alters urine ion concentrations, and is an efficacious urinary acidifier in goats. Goats treated with prolonged anionic dietary supplementation should be monitored for secondary osteoporosis from chronic urinary calcium loss.

    Several studies have looked at the relationship between childhood atopic disease and health-related quality of life (HRQoL), but existing research is limited by selected populations, small samples or lack to consider each of the three atopic conditions simultaneously. Impact of 4-week and 12-month occurrences of the three conditions on HRQoL were analysed by the use of complex sample general linear models alone and adjusted for the other atopic conditions, sociodemographics and mental health in a population-based sample (n = 6,518) of children and adolescents aged 11-17. In univariate analyses, total HRQoL was significantly impacted by eczema and hay fever but not asthma with stronger effects for 4-week occurrence. In multivariate analyses, 12-month occurrence of hay fever and 4-week occurrence of eczema and hay fever significantly impacted on total HRQoL. Although most of the variance in HRQoL was explained by mental health, independent effects of the atopic conditions remained. Atopic conditions impact HRQoL over and above mental health. When analysing the relationship between atopic conditions and HRQoL, it is important to consider more immediate versus less immediate effects of the conditions. Extent of impairment and the domains affected appear to vary when different time intervals are used.

    The present study was carried out to investigate changes in milk yield and composition of Najdi ewes fed 25 % Moringa oleifera (MOD) or Moringa peregrina (MPD) leaf diets as a supplement to alfalfa hay diet (AHD). Thirty ewes (average 55 kg, 2 years old) were randomly sorted into three experimental groups with 10 animals each and were fed for a 6-week period with these diets (AHD, MOD, or MPD). Diets dry matter, crude protein, and crude fiber were comparable, while fat, nitrogen-free extract (NFE), neutral detergent fiber (NDF), acid detergent fiber (ADF), metabolizable energy (ME), total phenolic, and antioxidant activity varied (p ≤ 0.05) between the diets. Feeding ewes with MOD increased (p ≤ 0.05) the milk yield compared to those fed AHD while milk composition was similar (p ≤ 0.05) between treatments. The concentration of malondialdehyde (MDA) in the ewes' milk and serum was lower (p ≤ 0.05) for MOD, while the total antioxidant capacity, catalase activity, and vitamin C contents were increased (p ≤ 0.05). The serum cholesterol and glucose of the ewes were lower (p ≤ 0.05) for those fed MOD. Moringa diets increased (p ≤ 0.05) average daily weight gain of lambs compared to those fed alfalfa diets. The results obtained showed that the inclusion of Moringa, especially M. oleifera, in the diet of Najdi ewes can improve milk yield and quality.

    Canadian agricultural operations contribute approximately 8% of national GHG emissions each year, mainly from fertilizers, enteric fermentation, and manure management (Environment Canada, 2010). With improved management of cropland and forests, it is possible to mitigate GHG emissions through carbon (C) sequestration while enhancing soil and crop productivity. Tree-based intercropped (TBI) systems, consisting of a fast-growing woody species such as poplar (Populus spp.) planted in widely-spaced rows with crops cultivated between tree rows, were one of the technologies prioritized for investigation by the Agreement for the Agricultural Greenhouse Gases Program (AAGGP), because fast growing trees can be a sink for atmospheric carbon-dioxide (CO2) as well as a long-term source of farm income (Montagnini and Nair, 2004). However, there are relatively few estimates of the C sequestration in the trees or due to tree inputs (e.g., fine root turnover, litterfall that gets incorporated into SOC), and hybrid poplars grow exponentially in the first 8-10 years after planting. With the current study, our objectives were (1) to evaluate spatial variation in soil C and nitrogen (N) storage, CO2 and nitrogen oxide (N20), and tree and crop productivity for two hybrid poplar-hay intercrop systems at year 9, comparing TBI vs. non-TBI systems, and (2) to evaluate TBI systems in the current context of C trading markets, which value C sequestration in trees, unharvested crop components, and soils of TBI systems. The study results will provide meaningful measures that indicate changes due to TBI systems in the short-term and in the long-term, in terms of GHG mitigation, enhanced soil and crop productivity, as well as the expected economic returns in TBI systems.

    Flue gas desulfurization gypsum (FGDG) from coal-fired power plants is readily available for agricultural use in many US regions. Broiler litter (BL) provides plant available N, P, and K but can be a source of unwanted As, Cu, and Zn. As a source of Ca and S, FGDG can reduce losses of P and other elements in runoff from BL-amended areas. Rainfall simulation plots (2.0 m) were established on a Piedmont Cecil soil growing 'Coastal' bermudagrass ( L.) for hay. Accumulation and transport of As, Cu, Cd, Cr, Hg, Pb, and Zn were evaluated after annual BL applications (13.5 Mg ha) with four FGDG rates (0, 2.2, 4.5, 9.0 Mg ha) and two FGDG treatments (0 and 9 Mg ha) without BL. Runoff As concentrations were sixfold greater with BL than without ( ≤ 0.01) and were similar to BL with FGDG at 2.2, 4.5 or 9.0 Mg ha ( ≤ 0.10). Runoff concentrations of target elements did not increase where FGDG was applied alone. After three annual applications of FGDG and BL, soil concentrations of As, Cr, Pb, Hg, and Cu were well below levels of environmental concern. Our findings indicate that runoff losses of As from BL application are not reduced with FGDG but support other research indicating no identifiable environmental risks from FGDG beneficial use in agricultural systems.

    The objective of this study was to compare carcass and meat quality between Barbarine lambs raised on rangelands and those reared indoors. A total of 24 weaned male lambs (23.2 kg) were allotted into two groups. The first group (GS) grazed pasture dominated by natural shrubs and was supplemented with 100 g of concentrate. The second group (HS) received oat hay and 200 to 300 g supplement of the same concentrate in order to obtain the same average daily gain (ADG) as the GS group. Six lambs from each group were slaughtered. Lambs to be slaughtered were randomly identified at the beginning of the trial. Carcass traits (offals percentage, dressing percentage, cuts yield, tissue composition, fatness and conformation) were determined; pH and meat and fat color were measured. Samples from longissimus lumborum were collected to analyze fatty acid composition. The GS group was characterized by a higher offals percentage, associated with higher lungs, heart, liver and kidney percentage. Carcass dressing percentage defined as the rate between hot carcass weight and empty BW was lower by 3.4% in the GS group. No differences were observed for carcass meat yield and carcass and leg compactness. Shoulder bone percentage of the GS group was higher, without differences in fat and lean percentages. Fat thickness, kidney and tail fats were lower in the GS lambs. However, intramuscular fat content was not affected. Percentages of saturated fatty acids and polyunsaturated fatty acids (PUFA) were not modified, whereas levels of n-3 and long n-3PUFA (EPA, DPA and DHA) as well as Δ5 desaturase plus Δ6 desaturase index were higher for the GS group. Thrombogenic and atherogenic indexes were not altered. No significant effects were observed for meat pH, meat and fat color. Despite having the same ADG, lambs from the GS group were less fatty, and their meat was richer in beneficial fatty acids.

    Full Text Available Introducción: Las comunidades indígenas presentan un mayor riesgo de inseguridad alimentaria y malnutrición, menor disponibilidad de recursos, y una creciente dependencia de alimentos más baratos aunque con un alto grado de procesamiento. Objetivo: Identificar el estado nutricional y aspectos alimentarios en mujeres indígenas de tres comunidades del Departamento de Presidente Hayes, Chaco Paraguayo. Metodología: Estudio observacional de diseño transversal con componente analítico, que incluyó a 81 mujeres de 15 a 44 años de edad, de las etnias Maká y Toba Qom. Previo consentimiento informado, se realizó la valoración nutricional y la entrevista para obtener los datos sociodemográficos y alimentarios. Resultados: Las mujeres indígenas presentaron una frecuencia de sobrepeso de 30,8% y obesidad del 21,0%, mientras que el 1,2 % presentó desnutrición. No encontramos diferencia significativa entre las etnias, en relación al sobrepeso y obesidad, (p>0,05. Observamos que las indígenas tenían una alta ingesta de frutas, azúcares y mieles. El 87 y 88% de las mujeres indígenas de ambas etnias estudiadas refirieron no consumir lácteos y derivados y entre 65 y 69% refirieron no consumir verduras. Conclusiones: Observamos un elevado porcentaje de obesidad y sobrepeso, un bajo consumo de lácteos y verduras y un alto consumo de azúcares, relacionados posiblemente a cambios en los aspectos alimentarios y sus costumbres, influenciados por la cercanía a las zonas urbanas y el acceso a alimentos de menor precio y mayor contenido energético.

    The objective of this study was to investigate the effects of 2 alfalfa hays differing in undigested neutral detergent fiber content and digestibility used as the main forage source in diets fed to high producing cows for Parmigiano-Reggiano cheese production. Diets were designed to have 2 different amounts of undigestible NDF [high (Hu) and low (Lu)], as determined by 240-h in vitro analysis (uNDF 240 ). Alfalfa hay in vitro digestibility [% of amylase- and sodium sulfite-treated NDF with ash correction (aNDFom)] at 24 and 240 h was 40.2 and 31.2% and 53.6 and 45.7% for low- (LD) and high-digestibility (HD) hays, respectively. The 4 experimental diets (Hu-HD, Lu-HD, Hu-LD, and Lu-LD) contained 46.8, 36.8, 38.8, and 30.1% of alfalfa hay, respectively, 8.6% wheat straw, and 35.3% corn (50% flake and 50% meal; DM basis). Soy hulls and soybean meal were used to replace hay to balance protein and energy among diets. Eight multiparous Holstein cows (average milk production = 46.0 ± 5.2 kg/d, 101 ± 38 d in milk, and 662 ± 42 kg of average body weight) were assigned to a 4 × 4 Latin square design, with 2 wk of adaptation and a 1-wk collection period. Dry matter and water intake, rumination time, ruminal pH, and milk production and composition were measured. Diets and feces were analyzed for NDF on an organic matter basis (aNDFom), acid detergent fiber, acid detergent lignin, and uNDF 240 to estimate total-tract fiber digestibility. Dry matter intake and rumination times were higher in HD diets compared with LD diets, regardless of forage amount. Rumination time was constant per unit of dry matter intake but differed when expressed as a function of uNDF 240 , aNDFom, or physically effective NDF intake. No differences were found among treatments on average ruminal pH, but the amount of time with pH digestible neutral detergent fiber fraction digestibility was higher for the LD diets (88.3 versus 85.8% aNDFom in HD), for which lower feed intakes were also observed.

Trata-se de um estudo de inspiração etnográfica, que utilizou como fonte de pesquisa entrevistas com operadoras/os do direito e diários de campo, construídos a partir de observação de audiências e análise documental de processos penais. A pesquisa mostrou que as práticas rotineiras das/os operadoras/es do direito, no tratamento jurídico de casos tipificados como de “violência doméstica e familiar contra a mulher”, estavam orientadas pelos “estilos” pessoais de cada magistrado/a ao conduzir as audiências de ratificação, caracterizando formas de comunicação e interação de acordo com valores morais, marcados por diferentes concepções de gênero, família e justiça. A observação das práticas de equacionamento e julgamento evidenciou que os modos de produção de justiça estavam aliados à dimensão moral, de certa forma velada nos discursos dos/as operadores/as do direito, ao fazerem uso dos códigos legais. As posições políticas dessas/es profissionais, acerca do processo de criminalização da “violência doméstica e familiar contra a mulher”, resultaram, muitas vezes, em práticas contrárias às expectativas dos movimentos feministas com a criação da Lei Maria da Penha, mostrando a importância do debate sobre a judicialização das relações sociais no campo dos estudos de gênero.

    Full Text Available RESUMEN: Tras un esbozo de críticas recientes, el artículo analiza el concepto de subjetividad en la filosofía alemana clásica. Se señala que la apercepción pura en Kant es el principio de la lógica formal sin rastros de psicologismo, y que Kant ofrece las determinaciones básicas de la apercepción pura y de su «Yo pienso». Fichte continúa el problema de la relación entre lógica y subjetividad, y apuesta por la prioridad de la subjetividad. Su estructura se explica en detalle en una historia sistemática de la autoconciencia. Se muestra que éste es un nuevo programa idealista, que es desarrollado mucho más en la filosofía del joven Schelling. La subjetividad de acuerdo con este último programa se explica como un sistema dinámico de facultades y de estados del sujeto; por ello, la subjetividad no se fija en la relación sujeto-objeto y no se expone a la objeción de circularidad. Esto también es válido para Hegel en su «Fenomenología del Espíritu», que es esencialmente tal historia sistemática de la autoconciencia. El propósito final en Fichte es la voluntad moral; en Schelling, el genio estético; en Hegel, el conocimiento absoluto, el cual se expone en un orden sistemático de categorías, que Hegel echa de menos en Kant. En estas categorías, de acuerdo con Hegel, la subjetividad se piensa a sí misma.ABSTRACT: After a sketch of modern critics is analysed the concept of subjectivity in classical Germán philosophy. It is pointed out that puré apperception in Kant is the principie of formal logic without any psychologism, and that Kant gives basic determinations of puré apperception and its «I think». In Fichte is continued the problem of the relation between logic and subjectivity, and he votes for the priority of subjectivity. Its structure is explained in detail in a systematic history of self-consciousness. It is shown that this is a new idealistic program, that is further developed in the philosophy of the

    This experiment was conducted to determine the effects of corn silage (CS) hybrids and quality of alfalfa hay (AH) in high-forage dairy diets on N utilization, ruminal fermentation, and lactational performance by early-lactating dairy cows. Eight multiparous Holstein cows were used in a duplicated 4 × 4 Latin square experiment with a 2 × 2 factorial arrangement of dietary treatments. The 8 cows (average days in milk = 23 ± 11.2) were surgically fitted with ruminal cannula, and the 2 squares were conducted simultaneously. Within square, cows were randomly assigned to a sequence of 4 diets: conventional CS (CCS) or brown midrib CS (BMR) was combined with fair-quality AH [FAH: 46.7% neutral detergent fiber (NDF) and 18.4% crude protein (CP)] or high-quality AH (HAH: 39.2% NDF and 20.7% CP) to form 4 treatments: CCS with FAH, CCS with HAH, BMR with FAH, and BMR with HAH. Diets were isonitrogenous across treatments, averaging 15.9% CP. Each period lasted a total of 21 d, with 14 d for treatment adaptation and 7d for data collection and sampling. Intake of DM and milk yield did not differ in response to CS hybrids or AH quality. Although feeding BMR-based diets decreased urinary N output by 24%, it did not affect fecal N output. Feeding HAH decreased urinary N output by 15% but increased fecal N output by 20%. Nitrogen efficiency [milk N (g/d)/intake N (g/d)] tended to increase for BMR treatments. Ruminal ammonia-N concentration was lower for cows fed BMR-based diets than for those fed CCS-based diets but was not affected by quality of AH. Feeding BMR-based diets or HAH decreased milk urea N concentration by 23 or 15%, respectively, compared with CCS-based diets or FAH. Total volatile fatty acid concentration increased with HAH but was not influenced by CS hybrids. Feeding BMR-based diets decreased urinary N-to-fecal N ratio (UN:FN), and it was further reduced by feeding HAH. Although cows fed the BMR-based diets tended to increase milk N-to-manure N ratio, the

    Full Text Available Neste artigo analisamos os modos de regulação de uma atividade - as explicações - que é hoje um caso de sucesso em todo o mundo como oferta educativa privada e que podemos mesmo considerar paralela à do modelo escolar. Num primeiro momento, procedemos à caracterização das políticas de regulação em escala global: a situação nos países que ignoram a atividade das explicações; o caso dos países que escolheram a via da proibição, total ou parcial; o caso dos países que reconheceram a atividade e até formularam políticas educacionais que encontraram nas explicações um aliado para a melhoria dos resultados escolares. Abordaremos depois a situação em Portugal, país onde a atividade existe desde há muito, mas que conhece na atualidade um vigor novo e maior visibilidade social. Quanto às políticas de regulação das explicações em Portugal, podemos falar de uma regulação burocrática sem grande eco na prática dos profissionais, dos estudantes e das famílias. Terminaremos com algumas reflexões sobre a necessidade de se dar dimensão pública à discussão sobre a atividade das explicações, tantas e tão sérias são as suas repercussões sociais e políticas, nomeadamente em matéria de democratização do acesso e do sucesso escolares, questão nuclear que está no cerne da preocupação com a equidade no seio das políticas públicas.In this text we analyze the ways of regulation of private tutoring, an activity that is at present a success story as a private educational product with an widespread use across the world that we can even see as parallel to that of the school model.

    Our objective was to determine whether experience early in life and adaptation time (up to 72 days) to tannin-rich diets affect feed intake, digestion, nitrogen balance, and growth in Barbarine lambs given tannin-containing (Acacia cyanophylla Lindl., acacia) or tannin-free (oaten hay) diets later in life. Twelve experienced lambs (live-weight, LW: 13.2 {+-} 2.0 kg) were divided into two equal groups. Each group received air-dried acacia (tannin-containing diet) or oaten hay (hay, tannin free-diet) ad libitum. Twelve other inexperienced lambs (LW 12.3 {+-} 2.5 kg) were also divided into two equal groups. Each group received one of the above two diets. All animals were 4 months old at the start of this experiment and were supplemented with 300 g concentrate. To investigate the carry-over effect of tannins, the acacia-diet was removed on day 73, thus all lambs received thereafter the hay-diet for a further 24 days before starting a 6-day faecal collection period. Irrespective to early experience and adaptation time, the nutritive value of hay-diet was higher than that of acacia-diet and consequently lambs given hay performed better than those receiving acacia (P = 0.0001). Animals exposed to tannins early in life exhibited higher digestible crude protein intake (P = 0.0389), retained more N (P = 0.0963) and excreted more allantoin in urine (P = 0.0248) than the inexperienced lambs. Except plasma urea (P = 0.2923), the adaptation period to experimental diets affected significantly all measured parameters (P 0.0001). Animals adapted to diets for only 6 days exhibited the lowest acacia or hay intake and the highest diet digestibility compared to those adapted to these diets for 24, 48 or 72 days. Weight losses of inexperienced lambs adapted to acacia-diet for 6 days were associated with negative nitrogen balance. Sheep which received the acacia-diet, followed by the hay diet, had similar hay intake, diet digestibility, N balance and growth rate as compared to those

    The aim of the study was to compare the in vivo anthelmintic activity of sainfoin hay (Onobrychis viciifolia) and carob pod meal (Ceratonia siliqua) against gastrointestinal nematodes. Seven days before infection, 64 naive lambs were assigned to four different groups: Group S received sainfoin hay and group CAR was fed with carob pods. The remaining lambs received lucerne hay (Medicago sativa) and were assigned to positive (non-treated, NT) and negative (treated, T) control groups (treatment with albendazole). On day 0, lambs were artificially trickle infected for 6 weeks, with a mixture of infective larvae of Haemonchus contortus and Trichostrongylus colubriformis. Parasitological and pathophysiological parameters were measured repeatedly during the 2-month study. Compared to the NT group, decreases in egg excretion were observed in the CAR and S groups with significant differences only found for sainfoin (p < 0.05). At necropsy, group S showed decreases in the total worm numbers of both nematode species with significant differences for H. contortus. In contrast, no differences were noticed for the CAR group. Compared to the NT group, lower values for fecundity of female H. contortus were found in the S and CAR groups, however differences were non-significant. No differences in body weight gains were found between groups. Consistent results were found showing significantly higher packed cell volume (PCV) values in the T and S groups compared to NT and CAR groups. Overall, these results confirm a positive effect associated with the feeding of lambs with tanniniferous resources on host resilience (PCV values) and against gastrointestinal parasitic nematodes by affecting some biological traits of worm populations (e.g. eggs per gram of faeces and worm numbers). However, the anthelmintic effects differed between the two tannin-containing resources, which might be associated with the quantity and/or quality of secondary metabolites (condensed tannins and/or other

    Efficient conversion of lignocellulosic biomass to fermentable sugars requires the synergistic action of multiple enzymes; consequently enzyme mixtures must be properly formulated for effective hydrolysis. The nature of an optimal enzyme blends depends on the type of pretreatment employed as well the characteristics of the substrate. In this study, statistical experimental design was used to develop mixtures of recombinant glycosyl hydrolases from thermophilic and anaerobic fungi that enhanced the digestion of alkaline peroxide treated alfalfa hay and barley straw by mixed rumen enzymes as well as commercial cellulases (Accelerase 1500, A1500; Accelerase XC, AXC). Combinations of feruloyl and acetyl xylan esterases (FAE1a; AXE16A_ASPNG), endoglucanase GH7 (EGL7A_THITE) and polygalacturonase (PGA28A_ASPNG) with rumen enzymes improved straw digestion. Inclusion of pectinase (PGA28A_ASPNG), endoxylanase (XYN11A_THITE), feruloyl esterase (FAE1a) and β-glucosidase (E-BGLUC) with A1500 or endoglucanase GH7 (EGL7A_THITE) and β-xylosidase (E-BXSRB) with AXC increased glucose release from alfalfa hay. Glucose yield from straw was improved when FAE1a and endoglucanase GH7 (EGL7A_THITE) were added to A1500, while FAE1a and AXE16A_ASPNG enhanced the activity of AXC on straw. Xylose release from alfalfa hay was augmented by supplementing A1500 with E-BGLUC, or AXC with EGL7A_THITE and XYN11A_THITE. Adding arabinofuranosidase (ABF54B_ASPNG) and esterases (AXE16A_ASPNG; AXE16B_ASPNG) to A1500, or FAE1a and AXE16A_ASPNG to AXC enhanced xylose release from barley straw, a response confirmed in a scaled up assay. The efficacy of commercial enzyme mixtures as well as mixed enzymes from the rumen was improved through formulation with synergetic recombinant enzymes. This approach reliably identified supplemental enzymes that enhanced sugar release from alkaline pretreated alfalfa hay and barley straw.

    The effects of feeding graded levels of dried moringa (Moringa stenopetala) leaf on intake, body weight gain (BWG), digestibility and nitrogen utilization were studied using male sheep (BW of 13.8 ± 0.12 kg). Six sheep were randomly allocated to each of the four treatment diets: Rhodes grass (Chloris gayana) hay offered ad libitum (T1), hay + 150 g moringa leaf (T2), hay + 300 g moringa leaf (T3), hay + 450 g moringa leaf (T4) were offered daily. A 7-day digestibility trial and an 84-day growth experiments were conducted. Dry matter (DM), organic matter (OM) and crude protein (CP) intakes increased (P moringa leaf in the diets. Sheep fed T2, T3 and T4 diets gained (P  0.05) among treatments. The digestibility of dietary CP increased (P moringa leaf, but there was no significant difference between T2 and T3 diets. The nitrogen (N) intake and urinary N excretion increased (P moringa leaf. The N retention was highest (P moringa leaf supplementation. The control group was in a negative N balance. Supplementing a basal diet of Rhodes grass hay with dried moringa leaves improved DM intake, BWG and N retention. It is concluded that M. stenopetala can serve as a protein supplement to low-quality grass during the dry season under smallholder sheep production system.

    Eighteen dual purpose goats were used to evaluate the effects of feeding Calliandra caryothyrus leaf meal at different patterns as a supplement to Rhodes grass hay on intake, nitrogen utilization and milk yield. A basal diet of low quality Rhodes grass hay (fed at 90% ad libitum) and 100 g maize germ were offered to the goats over a 60-day experimental period. The treatments were:- (T1) 100 g day -1 calliandra for 60 days; (T2) 200 g day -1 calliandra for 30 days followed by another 30 days where 200 g or 0 g day -1 calliandra were alternated every 5 days; and (T3) 200 g or 0 g day -1 alternated every 5 days for 60 days. Total dry matter intake (DMI) was significantly (p -1 for T1, T2 and T3, respectively.Milk Yields had similar trend and averaged 166.1, 231.8 and 201.1 g day -1 for T1, T2, and T3, respectively. The utilization of nitrogen was also significantly (p<0.05) affected by pattern of supplement feeding. It was concluded from the results that the overall animal response could be influenced by how a limited quantity of supplement was fed

    Full Text Available Em consonância com uma psicologia mais afeita ao devir do que às essências, a proposta deste artigo é fundamentar a importância de se compreender a tradicional concepção de subjetividade enquanto um processo de subjetivação, principalmente no que tange as discussões sobre identidade e gênero na atualidade. Feito isso, traçamos algumas aproximações entre arte e psicologia, compreendendo a primeira como um potente dispositivo para favorecer modos de subjetivação que tenham a diferença como inerência relacional. Por fim, lançamos nossos olhares em alguns fragmentos da obra Cremaster do artista contemporâneo Mathew Barney para perceber o modo como a obra ultrapassa os binarismos de gênero e lança linhas pós-identitárias de subjetivação.

    The objective was to evaluate feed intake, digestibility, body weight change and carcass characteristics of sheep fed a basal diet of hay supplemented with banana leaves and silver leaf desmodium. Thirty yearling lambs with an average initial body weight of 15.85 ± 1.6 kg were grouped into six blocks of five rams in each block. The treatments were: hay alone (T1), hay + 100% banana leaf (T2), hay + 67% banana leaf + 33% desmodium leaf (T3), hay + 33% banana leaf + 67% desmodium leaf (T4) and hay + 100% desmodium leaf (T5). Three hundred grams of treatment diets were offered daily on as fed basis. The feeding and digestibility trial lasted for 84 and 7 days, respectively, followed by carcass evaluation. The total dry matter (DM) intake for T3, T4 and T5 were greater (P T4 > T3 > T2 > T1. Rams lambs receiving supplementary diets had higher (P<0.05) DM, OM, CP, neutral detergent fiber and acid detergent fiber digestibility compared with the control diet. The empty body weight and slaughter weight was highest (P<0.05) in rams receiving T3, T4 and T5 diets. The average daily gain and feed conversion efficiency was highest (P<0.05) in rams receiving the supplementary diets. The DP on the basis of hot carcass weight linearly increased with increasing levels of desmodium. Rams reared on supplementary diet had higher (P<0.05) rib eye area compared with the control diet. In conclusion, when banana leaf is used as a supplement to poor quality grass, better response was obtained when fed in combination with desmodium.

    Forty-four lactating Holstein cows (173±30 DIM, 42.5±6.8 kg of milk, 4.03±0.69% fat, 674±78 kg of body weight) were used in an 8-wk, completely randomized trial with a 2 × 2 factorial arrangement of treatments to determine the effect of forage source and supplemental cellulase enzyme on performance. Treatments included 2 forage combinations (corn silage plus 12.2% dry matter, DM, from either alfalfa hay or Tifton 85 bermudagrass haylage) with or without a commercial cellulase enzyme applied to the total mixed ration at the rate of 4 g/head per day (Promote N.E.T.-L, Cargill Animal Nutrition, Minneapolis, MN). Experimental diets were formulated to provide similar concentrations of protein (16.5% of DM), energy (1.63 Mcal of net energy for lactation/kg of DM), and neutral detergent fiber (41.7% of DM) and were fed once daily as a total mixed ration behind Calan doors for ad libitum intake. The cellulase enzyme provided 1,200 cellulase units of activity/g of product and was applied to the total mixed ration and allowed to mix for 5min before feeding. Before beginning the trial, all cows were trained to use Calan (American Calan, Northwood, NH) doors and then fed the alfalfa hay-based diet for 2 wk. Data collected during wk 2 were used as a covariate in the statistical analysis. At the beginning of the 6-wk experimental period, cows were assigned randomly to 1 of the 4 experimental diets. No interactions were observed between forage and enzyme for any measures. Daily DM intake; milk yield; concentrations of milk fat, true protein, lactose, and solids not fat; energy-corrected milk yield; and dairy efficiency were not different among alfalfa or Tifton 85 bermudagrass rations with or without cellulase enzyme supplementation. The results of this trial indicate that Tifton 85 bermudagrass haylage can replace alfalfa hay in diets fed to high-producing, lactating dairy cows without depressing DM intake or milk yield when rations are balanced for NDF.

    The objective of this study was to evaluate in lactating cows the effect of either chopping or ensiling of wheat roughage on: intake, digestibility, lactation performance and animal behavior. Three groups of 14 lactating cows each, were fed total mixed rations (TMRs) based on either long wheat hay (HL), short wheat hay (HS) or wheat silage (SI), as the sole roughage source (30% of TMR dry matter (DM)). Parameters examined: sorting behavior, DM intake, milk yield and composition, rumination, recumbence, average daily rumen pH, digesta passage rate, and in-vivo digestibility. Performance data was summarized by day and analyzed using a proc-mixed model. The content of physically effective neutral detergent fiber (peNDF) was similar in the HL and SI and lower in the HS, resulting in similar differences among the three corresponding TMRs. In vitro DM digestibility of wheat silage was higher than that of the two hays (65.6% v. 62.8%) resulting in higher in vitro DM digestibility of the SI-TMR compared with the hay-based TMRs (79.3 v. 77.0%). HS-TMR was better than HL- or SI-TMRs at preventing feed sorting by cows after 12 or 24 h eating of the diets. Cows fed HS-TMR consumed more DM and NDF but less peNDF than the other two groups. Average daily rumen pH was similar in the three groups, but daily rumination time was highest in the cows fed HS-TMR. Rumen retention time was longest in cows fed HL-TMR. DM digestibility in cows fed SI-TMR was higher than that of HS and HL groups (65.2%, 61.8% and 62.4%, respectively), but NDF digestibility was similar in the three treatments. The highest intake of digestible DM was observed in cows fed SI-TMR, HS cows were intermediate and HL cows were the lowest. Consequently, cows fed SI-TMR had higher yields of milk, 4% fat corrected milk and energy-corrected milk (47.1, 42.9 and 43.2 kg/day, respectively) than cows fed HS-TMR (45.7, 41.0 and 41.0 kg/day, respectively) or HL-TMR (44.1, 40.3 and 40.3 kg/day, respectively).

    A colonic separation mechanism (CSM) is the prerequisite for the digestive strategy of coprophagy. Two different CSM are known in small herbivores, the 'wash-back' CSM of lagomorphs and the 'mucous-trap' CSM of rodents. Differences between these groups in their digestive pattern when fed exclusively hay were investigated in six rabbits (Oryctolagus cuniculus) and six guinea pigs (Cavia porcellus). Intake, digestibility (by total faecal collection), solute and particle mean retention times (MRT, using Co-EDTA and Cr-mordanted fibres) were measured. Rabbits selected less fibrous parts of the hay than guinea pigs, leaving orts with higher content of neutral detergent fibre [NDF; 721 ± 21 vs. 642 ± 31 g/kg dry matter (DM) in guinea pigs]. They also expressed a lower NDF digestibility (0.44 ± 0.10 vs. 0.55 ± 0.05 of total), a similar particle MRT (15 ± 3 vs. 18 ± 6 h), a longer solute MRT (51 ± 9 vs. 16 ± 4 h), and a lower calculated dry matter gut fill (19.6 ± 4.7 vs. 29.7 ± 4.1 g DM/kg body mass) than guinea pigs (p bacterial matter from the colonic digesta plug than the 'mucous-trap' CSM found in the guinea pigs. Related to metabolic body mass, rabbits therefore need a less capacious colon for their CSM where a more efficient bacteria wash-out is reflected in the lower fibre digestibility. A lighter digestive tract could contribute to a peculiarity of lagomorphs: their ability to run faster than other similar-sized mammals. © 2010 Blackwell Verlag GmbH.

    Welsh-cross pony geldings (about 300 kg live weight) were used in a 4x4 Latin square experiment to determine the rate of passage and apparent digestibility of unchopped big-bale grass silage (BBL), chopped big-bale grass silage (BBS), unchopped grass hay (HL) and chopped grass hay (HS) offered at approximately 15 g/kg live weight per d. On day 1 of collection weeks, ponies were fed 85 g ytterbium chloride hexahydrate-marked feed 1.5 h after the morning meal. Total faecal collections commenced 8 h later and continued for 168 h. Apparent digestibilities of feed DM, organic matter (OM), crude protein (CP, Nx6.25), acid-detergent fibre (ADF) and neutral-detergent fibre (NDF) were also determined. Faecal excretion data were subjected to the models of Pond et al. (1988) and digesta mean retention time (MRT) calculated from these models and using the algebraic method of Thielmans et al. (1978). Silage had significantly (Peffect. All the models of Pond et al. (1988) accurately described (R(2)>0.8) the pattern of faecal marker excretion. MRT of BBL (29.0 h)>BBS(27 h)>HS and HL (26 h). Compartmental analysis using the G3 model of Pond et al. (1988) showed BBL and HS diets had longer MRT in the time-dependent compartment, whereas BBS and HL had longer MRT in the time-independent compartment. Results from this experiment indicate that BBL and BBS are readily accepted and digested by ponies. While Yb is a successful external marker for determining total tract MRT and for modelling faecal excretion curves in horses, the results did not allow any definite conclusions to be drawn on digesta MRT within the different compartments of the equid gut.

    Understanding Pb removal from the translocation stream is vital to engineering Pb hyperaccumulation in above ground organs, which would enhance the economic feasibility of Pb phytoextraction technologies. We investigated Cu, Pb, Sb and Zn distributions in Hay-scented fern (Dennstaedtia punctilobula) rhizomes on shooting range soils by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), analyzing digested rhizomes, stems, and fronds using ICP-MS. Nutrients Cu and Zn concentrated in fronds while toxic elements Pb and Sb did not, showing potential Pb and Sb sequestration in the rhizome. Frond and rhizome concentration of Pb was 0.17 ± 0.10% and 0.32 ± 0.21% of dry biomass, respectively. The 208 Pb/ 13 C and 121 Sb/ 13 C determined by LA-ICP-MS increased from inner sclerotic cortex to the epidermis, while Pb concentrated in the starchy cortex only in contaminated sites. These results suggest that concentration dependent bioaccumulation in the rhizome outer cortex removes Pb from the vascular transport stream. - Highlights: ► Bioimaged Cu, Pb, Sb, Zn across fern rhizomes from shooting ranges using LA-ICP-MS. ► Pb levels were highest in the outer starchy cortex. ► Pb seemed to displace nutrients Cu and Zn in contaminated site rhizomes. ► [Pb] and [Sb] were correlated across organs suggesting similar transport factors. - Using LA-ICP-MS we determined elemental distributions in Hay-scented fern rhizomes including concentration dependent Pb sequestration patterns in the outer cortex.

    Twelve artificially reared, male Holstein calves, ruminally cannulated at 53 d of age, were used in a split-plot design to study the effects of no milk replacer reduction (CON), or reduction by 30% (30R) or 60% (60R) of this value on alfalfa hay intake and digestibility, ruminal fermentation and digestive kinetics. Milk replacer reduction began at 53 d of age and continued until 135 d of age, after which no milk replacer was fed. All calves had ad libitum access to long-stemmed alfalfa hay from birth. Five collection periods were conducted at average calf ages of 72, 87, 108, 129 and 151 d. Reducing the amount of milk replacer fed resulted in a linear increase (P less than .05) in forage OM intake; however, total OM intake (forage + milk) was not different (P greater than .10) among milk reduction groups. Size of particles in feces exhibited quadratic effects in response to milk replacer reduction (P less than .05) but only in the small (less than 150 microns) size groupings. Ruminal pH and ammonia and individual VFA concentrations (except isobutyrate) were not altered by milk reduction (P greater than .10) but increased (P less than .01) with calf age. Milk replacer reduction had a quadratic effect (P less than .05) on fluid outflow rate from the rumen, increasing as milk replacer was reduced. Other fluid and particulate kinetic data, as well as NDF digestion rate and DM digestion showed no effects (P greater than .10) from milk replacer reduction but changed with calf age. Milk replacer reduction increased forage intake but had minimal effects on digestive variables evaluated, suggesting that intake of milk replacer by calves can be reduced by up to 60% without disturbing forage fermentation and passage.

    To study the effect of weaning age on average daily gain (ADG), dry matter intake (DMI) and ruminal fermentation, 10 rumen-cannulated male Holstein calves were randomly assigned to one of two treatments: (i) early weaned at 8 weeks of age (235 l milk); (ii) conventionally weaned at 12 weeks of age (347 l milk). Twice daily grass hay (9.0 MJ ME x kg(-1) DM) and a dry total mixed ration (TMR) (11.6 MJ ME x kg(-1) DM) containing 15% alfalfa hay and 85% concentrates were offered separately. Water was available ad libitum. Ruminal fluid was collected via cannulas at weeks 9, 11, 13 and 15, twice weekly just prior to as well as 1, 3, 5 and 7 h after morning feeding. Calves of both treatments achieved adequate ADG (947 vs. 959 g; p > 0.05). Just-weaned calves rapidly increased DMI (1.1-2.5 kg TMR and 2.4-3.6 kg TMR for early- and conventionally-weaned calves, respectively). From weeks 10-12 early-weaned calves consumed significantly more dry feed than conventionally-weaned calves (week 10: 2.5 vs. 1.6 kg/d; week 12: 3.4 vs. 2.4 kg/d). Early weaning stimulates DMI supporting ruminal fermentation intensity, indicated by lower ruminal pH. After weaning, only early-weaned calves achieved critical average ruminal pH (week 9: 5.7 vs. 6.0, p = 0.017; week 11: 5.9 vs. 6.2, p = 0.007). Experimental treatment did not affect the concentration of ruminal short-chain fatty acids (SCFA). For all calves, the effects of the concentrate-rich TMR were shown by a high SCFA level (daily average: 137-152 mmol x l(-1)) and an acetate to propionate to butyrate ratio between 51:36:9 and 54:33:10.

P.Beauv. grass hay. Each goat was supplemented with 0, 23 or 30 g of PEG 4000 per day in addition to dietary mixture of A. karroo and S. verticillata hay. Polyethylene glycol 4000 supplementation had no effect (P > 0.05) on nutrient intake of goats. However, a diet × PEG (P goat were optimized at PEG 4000 supplementation levels of 19.62, 19.62, 19.61 and 19.53 g/goat/day, respectively, for diets containing 20% A. karroo leaf meal. Polyethylene glycol 4000 supplementation had no effect (P > 0.05) on the apparent digestibility of all nutrients. The dietary inclusion level of A. karroo leaf meal at 20% improved (P goats. Crude protein digestibility was optimized at a PEG 4000 supplementation level of 15.78 g/goat/day. Dietary mixture level and PEG 4000 supplementation had no effect (P > 0.05) on final weights of Pedi goats. Similar results were observed for blood urea and glucose concentrations of yearling male Pedi goats. However, daily body weight gain was higher (P goats fed 50% A. karroo leaf meal than those on 20% inclusion level. Polyethylene glycol 4000 has potential to improve the feeding value of tanninifeorus A. karroo leaf meal.

Porém, estas cidades têm seguido o mesmo caminho das cidades brasileiras mais populosas e negligenciado aspectos que garantam à manutenção das condições que favorecem investimentos públicos e principalmente privados. Em relação aos sistemas de transporte e logística, cada vez mais as cidades de porte médio têm se tornado dependente do uso do automóvel e evitado políticas de incentivo à mobilidade urbana sustentável. Desta forma, entender a percepção dos usuários dos sistemas de transporte urbano é fundamental para traçar medidas de incentivo para modos alternativos de viagens urbanas. O objetivo deste estudo é apresentar uma análise da percepção dos usuários quanto aos modos de deslocamento urbano, principalmente a bicicleta e medidas específicas de incentivo ao uso deste modo não motorizado. A pesquisa foi realizada por meio de entrevistas com um questionário impresso. As respostas possibilitaram obter a opinião sobre o uso da bicicleta como modo de transporte, caracterizar o perfil socioeconômico dos entrevistados e simular um cenário em relação ao uso da bicicleta. Para o caso específico deste estudo ficou evidente que os entrevistados são favoráveis ao uso da bicicleta e uma parcela está disposta a usar o ciclismo desde que sejam implantadas medidas de incentivo.

A síntese é a sistematização das interpretações e significados do risco. A análise apresenta a existência de dois modos de atuação, permitindo empreender a aplicação do significado de risco no âmbito do domínio de um saber específico. Entre a identificação do risco e a intervenção existem processos que mesclam a racionalidade à subjetividade, a autoridade ao controle, a experiência ao conhecimento formal adquirido. O agir do profissional da VISA é constituído por conhecimentos, pela experiência adquirida, pelos contextos socioculturais e pelas interações que definem e redefinem os modos de atuar. As ações são baseadas nos significados do risco que se deslocam no plano da objetividade e da subjetividade, e a legislação é um importante instrumento de decisão e de persuasão.

    The objective of this experiment was to evaluate the effects of replacing coastcross hay NDF by soybean hull (SH) NDF on the lactation performance and eating behavior of ewes and also on the performance of their lambs. Fifty-six Santa Inês lactating ewes (56.1 +/- 6.8 kg of initial BW; mean +/- SD) were penned individually and used in a randomized complete block design with 14 blocks and 4 treatments. Diets were formulated to provide similar concentrations of NDF (56%) and CP (16%). The SH NDF replaced 33 (SH33), 67 (SH67), or 100% (SH100) of the NDF contributed by coastcross hay in a 70% forage-based diet (SH0), resulting in SH inclusion rates of 0, 25, 54, and 85% of the dietary DM. Once a week, from the second to the eighth week of lactation (weaning time), ewes were separated from their lambs, stimulated by a 6-IU i.v. oxytocin injection, and hand milked to empty the udder. After 3 h, milk production was obtained after the same procedure. Quadratic effect for milk production (142.4, 179.8, 212.6, and 202.9 g/3 h) and cubic effect for DMI (2.27, 2.69, 3.25, and 3.00 kg/d) were observed as SH inclusion increased from 0 to 85% of the dietary DM. Milk fat (7.59, 7.86, 7.59, and 7.74%), protein (4.53, 4.43, 4.40, and 4.55%), and total solids (18.24, 18.54, 18.39, and 18.64%) did not differ among the 70% forage-based diet and diets with SH NDF replacing 33, 67, or 100% of the NDF. A linear increase in lactose concentration was observed with SH inclusion. Ewe BW gain during the trial showed a cubic response (0.37, 0.03, 4.80, and 2.80 kg) with SH inclusion. The preweaning ADG of lambs increased linearly, and ADG of lambs after weaning decreased linearly with SH inclusion. Final BW of lambs (2 wk after weaning) did not differ among treatments. Eating behavior observations were conducted with 44 ewes. The same facilities, experimental design, dietary treatments, and feeding management were used. Observations were visually recorded every 5 min for a 24-h period when

  18. Corn silage versus corn silage:alfalfa hay mixtures for dairy cows: effects of dietary potassium, calcium, and cation-anion difference.

    2011-10-01

    Corn silage (CS) has replaced alfalfa hay (AH) and haylage as the major forage fed to lactating dairy cows, yet many dairy producers believe that inclusion of small amounts of alfalfa hay or haylage improves feed intake and milk production. Alfalfa contains greater concentrations of K and Ca than corn silage and has an inherently higher dietary cation-anion difference (DCAD). Supplemental dietary buffers such as NaHCO(3) and K(2)CO(3) increase DCAD and summaries of studies with these buffers showed improved performance in CS-based diets but not in AH-based diets. We speculated that improvements in performance with AH addition to CS-based diets could be due to differences in mineral and DCAD concentrations between the 2 forages. The objective of this experiment was to test the effects of forage (CS vs. AH) and mineral supplementation on production responses using 45 lactating Holstein cows during the first 20 wk postpartum. Dietary treatments included (1) 50:50 mixture of AH and CS as the forage (AHCS); (2) CS as the sole forage; and (3) CS fortified with mineral supplements (CaCO(3) and K(2)CO(3)) to match the Ca and K content of the AHCS diet (CS-DCAD). Feed intake and milk production were equivalent or greater for cows fed the CS and CS-DCAD diets compared with those fed the AHCS diet. Fat percentage was greater in cows fed the CS compared with the AHCS diet. Fat-corrected milk (FCM; 3.5%) tended to be greater in cows fed the CS and CS-DCAD diets compared with the AHCS diet. Feed efficiencies measured as FCM/dry matter intake were 1.76, 1.80, and 1.94 for the AHCS, CS, and CS-DCAD diets, respectively. The combined effects of reduced feed intake and increased FCM contributed to increased feed efficiency with the CS-DCAD diet, which contained 1.41% K compared with 1.18% K in the CS diet, and we speculate that this might be the result of added dietary K and DCAD effects on digestive efficiency. These results indicate no advantage to including AH in CS-based diets

    The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area’s water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and hydrostratigraphic units of the aquifers are needed. This report presents the detailed 1:24,000-scale bedrock hydrostratigraphic map as well as names and descriptions of the geologic and hydrostratigraphic units of the Driftwood and Wimberley 7.5-minute quadrangles in Hays and Comal Counties, Tex.Hydrostratigraphically, the rocks exposed in the study area represent a section of the upper confining unit to the Edwards aquifer, the Edwards aquifer, the upper zone of the Trinity aquifer, and the middle zone of the Trinity aquifer. In the study area, the Edwards aquifer is composed of the Georgetown Formation and the rocks forming the Edwards Group. The Trinity aquifer is composed of the rocks forming the Trinity Group. The Edwards and Trinity aquifers are karstic with high secondary porosity along bedding and fractures. The Del Rio Clay is a confining unit above the Edwards aquifer and does not supply appreciable amounts of water to wells in the study area.The hydrologic connection between the Edwards and Trinity aquifers and the various hydrostratigraphic units is complex because the aquifer system is a combination of the original Cretaceous depositional environment, bioturbation, primary and secondary porosity, diagenesis, and fracturing of the area from Miocene faulting. All of these factors have resulted in development of modified porosity, permeability, and transmissivity within and between the aquifers. Faulting produced highly fractured areas which allowed for rapid infiltration of water and subsequently formed solutionally enhanced fractures, bedding planes, channels, and caves that

    Seventy-two (36 in each of two consecutive years) lactating, British-crossbred cows (609 +/- 19 kg) were used to evaluate effects of feeding a feather meal-blood meal combination on performance by beef cows fed grass hay. Bromegrass hay (9.6% CP, DM basis) was offered ad libitum and intake was measured daily in individual Calan electronic headgates. Acclimation to Calan gates began approximately 20 d after parturition, and treatments were initiated 21 d later. Cows were assigned randomly to one of four treatments (DM basis) for 60 d: 1) nonsupplemented control (CON), 2) energy control (ENG; 790 g/d; 100% beet pulp), 3) degradable intake protein (DIP; 870 g/d; 22% beet pulp and 78% sunflower meal), or 4) undegradable intake protein (UIP; 800 g/d; 62.5% sunflower meal, 30% hydrolyzed feather meal, and 7.5% blood meal). Net energy concentrations of supplements were formulated to provide similar NE(m) intakes (1.36 Mcal/d). The DIP and UIP supplements were calculated to supply similar amounts of DIP (168 g/d) and to supply 64 and 224 g/d of UIP, respectively. Forage DMI (kg/d) decreased in supplemented vs. nonsupplemented (P = 0.03) and DIP vs. UIP (P = 0.001); however, when expressed as a percentage of BW, forage DMI was not different (P = 0.23). Supplemented cows tended (P = 0.17) to lose less BW than CON. Body condition change was not affected (P = 0.60) by postpartum supplementation. No differences were noted in milk production (P = 0.29) or in calf gain during the supplementation period (P = 0.74). Circulating insulin concentrations were not affected by treatment (P = 0.42). In addition, supplementation did not affect circulating concentrations of NEFA (P = 0.18) or plasma urea nitrogen (P = 0.38). Results of the current study indicate that supplementation had little effect on BW, BCS, milk production, or calf BW when a moderate-quality forage (9.6% CP) was fed to postpartum, winter-calving cows in optimal body condition (BCS > 5). Supplemental UIP did not enhance

    Full Text Available “An intertextual/ dialogical reading of place through photography and fiction” The article is an exploration of place and its representations based on the intertextual reading of a series of photographs (1880-82 of Tarbert, Loch Fyne by Andrew Begbie Ovenstone (1851-1935 and the dialogical reading of a novel, Gillespie (1914, by John MacDougall Hay (1881-1919 which is set in Tarbert. The proposed article is inspired by a sense that a semiotic approach to the subject will reveal far more than has been discovered within the tradition of hermeneutics and patrimony and that much will be gained by a study of the contrast between written and visual signifiers. The article raises questions about the (unexamined coded readings of place especially in relation to the photograph, and the lack of an adequately theorized tradition for the novel. The literary text is well known - if not well understood - but the images are from a rare, unpublished, private collection of photographs from Scotland, India and the furthest reaches of Empire (Ovenstone was the Atlantic Freight Manager of Anchor Line Ltd, the Glasgow shipping company. The paper emphasizes the need for the use of codes to decipher the texts. When we “read” the photographs we need to be aware of the intertextual relationship between the photograph and the landscape painting tradition as well as the common practice of the created tableau – there is then overlaid upon the image the sense of a set of conventions, a system which operates much like a language. We are able to discover through the notion of the “long quotation from appearances” the potential for more complex “synchronic” readings. Likewise, in the case of Gillespie, the novel operates within a genre which determines a “reading”. When we are aware of a code, we become aware of the way that Hay manoeuvres adroitly to thwart the reader’s best efforts to settle upon a preferred reading – especially one shaped by an

    Tarentaise heifers fitted with a rumen cannula (539 +/- 7.5 and 487 +/- 15.7 kg avg initial BW in Exp. 1 and 2, respectively) were used in two Latin square metabolism experiments having 2 x 2 factorial treatment arrangements to determine the effects of supplementation with Aspergillus oryzae fermentation extract (AO) or laidlomycin propionate (LP) on intake, digestion, and digestive characteristics of Neotyphodium coenophialum-infected (IF) or uninfected (FF) tall fescue (Festuca arundinacea) hay diets consumed ad libitum. Heifers were housed in individual stanchions in a metabolism facility with ambient temperatures controlled to range between 26.7 and 32.2 degrees C daily. Total feces and urine were collected for 5 d following a 21-d dietary adaptation period. In situ DM and NDF disappearance and ruminal fermentation characteristics were also determined. In Exp. 1, DMI was 24% greater (P or = 0.42). In Exp. 2, DMI was 18.9% greater (P < 0.01) by heifers offered FF than by those offered IF (6.6 vs 5.5 kg/d). Heifers fed LP (50 mg/d) consumed 10.6% less (P < 0.05) DM than those not fed LP (5.7 vs 6/5 kg/d). Digestibility of NDF tended to be greater (P = 0.08) and digestibility of ADF was greater (P < 0.05) from FF than from IF. Conversely, apparent N absorption (%) was greater (P < 0.05) from IF than from FF. Heifers fed LP had lower (P < 0.05) ADF digestibility than those not fed LP. In situ degradable DM and NDF fractions were greater (P < 0.01) from IF than from FF. Diets supplemented with LP had higher (P < 0.01) indigestible DM and NDF fractions than those without LP. Propionic acid and total VFA concentrations were greater (P < 0.05) from heifers offered FF than from those offered IF and from heifers fed LP than from those not fed LP. Therefore, it appears the major effect of N. coenophialum was a reduction in forage intake and total-tract fiber digestibility in certain situations. Response to the feed additives was similar whether heifers were offered IF or

Os tratamentos foram constituídos por cinco modos de incorporação: arado de discos mais duas gradagens, grade aradora mais duas gradagens, enxada rotativa, arado escarificador mais duas gradagens e distribuição na superfície sem incorporação, e por quatro doses de calcário dolomítico: 0, 2,8, 6,6 e 10,3 t ha-1, visando a elevar a saturação por bases do solo a 30, 60 e 90%. A planta teste utilizada foi o milho. Verificou-se que o modo de incorporação do corretivo no solo afeta a sua eficiência em relação à profundidade no perfil, na qual há neutralização da acidez. Houve elevação da saturação por bases do solo até a camada de 20cm, 15cm e 10cm, respectivamente, para os seguintes modos de incorporação: enxada rotativa, arado de discos ou grade aradora e arado escarificador ou calcário distribuído na superfície sem incorporação. Os valores de saturação por bases desejados não foram alcançados, três meses após a calagem, independente do modo de incorporação de calcário.The solubilization of lime in soil, without which the acidity neutralization does not occur, demands time and requires incorporation for increasing the contact between lime and soil coloides. In order to study the correction of soil acidity in function of lime incorporation manners, a field experiment was carried out, in Ponta Grossa, State of Paraná, Brazil, in a

    Metabolism of dietary nitrogen using labeled 15 N and the changes in the microbial protein mass and NH3-N were studied in five rumen-simulating-technique(RUSITEC)-fermenters, which were run simultaneously in three identically repeated experiments. Each experiment consisted of a 6-day adaptation period followed directly by a 3-day collection period. The feed of the fermenters (G1, G2, G3, G4 and G5) varied in the ratio of barley. The barley increased by 20% between the fermenters. Grass hay+barley (g/d) in the feed of the fermenters was 10+2 (G1), 8+4 (G2), 6+6 (G3), 4+8 (G4) and 2+10 (G5). The results indicated that there were no significant (P>0.05) changes in the amounts of microbial nitrogen (92-118 mg/d) and microbial mass syntheses which were (mg/d): 1154 (G1), 1063 (G2), 1152 (G3), 1127 (G4) and 1362 (G5). Increasing the proportion of barley in the fermenters (G4 and G5) decreased NH3-N amounts (G2 and G3) significantly (P<0.05). The energy was not efficiently used in G5 having a lower ratio of the microbial nitrogen and microbial mass to the total short chain fatty acids than that other fermenters. (authors)

    Geologic mapping of the Hines Creek Fault and the adjacent Trident Glacier and McGinnis Glacier Faults to the north in the eastern Alaska Range, Alaska, reveals that these faults were active during the Cenozoic. Previously, the Hines Creek Fault, which is considered to be part of the strike-slip Denali Fault system (Ridgway and others, 2002; Nokleberg and Richter, 2007), was interpreted to have been welded shut during the intrusion of the Upper Cretaceous Buchanan Creek pluton (Wahrhaftig and others, 1975; Gilbert, 1977; Sherwood and Craddock, 1979; Csejtey and others, 1992). Our geologic mapping along the west- to west-northwest-striking Hines Creek Fault in the northeastern Healy quadrangle and central to northwestern Mount Hayes quadrangle reveals that (1) the Buchanan Creek pluton is truncated by the Hines Creek Fault and (2) a tectonic collage of fault-bounded slices of various granitic plutons, metagabbro, metabasalt, and sedimentary rock of the Pingston terrane occurs south of the Hines Creek Fault.

    Bees are a key component of biodiversity as they ensure a crucial ecosystem service: pollination. This ecosystem service is nowadays threatened, because bees suffer from agricultural intensification. Yet, bees rarely benefit from the measures established to promote biodiversity in farmland, such as agri-environment schemes (AES). We experimentally tested if the spatio-temporal modification of mowing regimes within extensively managed hay meadows, a widespread AES, can promote bees. We applied a randomized block design, replicated 12 times across the Swiss lowlands, that consisted of three different mowing treatments: 1) first cut not before 15 June (conventional regime for meadows within Swiss AES); 2) first cut not before 15 June, as treatment 1 but with 15% of area left uncut serving as a refuge; 3) first cut not before 15 July. Bees were collected with pan traps, twice during the vegetation season (before and after mowing). Wild bee abundance and species richness significantly increased in meadows where uncut refuges were left, in comparison to meadows without refuges: there was both an immediate (within year) and cumulative (from one year to the following) positive effect of the uncut refuge treatment. An immediate positive effect of delayed mowing was also evidenced in both wild bees and honey bees. Conventional AES could easily accommodate such a simple management prescription that promotes farmland biodiversity and is likely to enhance pollination services. PMID:24416434

    Full Text Available Álvaro Uribe Vélez (2012 en sus memorias No hay causa perdida da cuenta de sus ocho años de presidencia pero también de ciertos elementos de su vida privada. Uno de los eventos que realza es el intento de secuestro y asesinato de su padre Alberto Uribe Sierra en 1983. Este evento, junto con el secuestro y muerte de otras reconocidas personalidades le sirven al narrador para recrear una atmósfera de zozobra y tensión para justificar toda su política de seguridad militar. Dado que las memorias están narradas de una manera maniquea y en la forma del thriller de suspenso, se utilizaron las herramientas de la narratología para desentrañar su alto contenido patriarcal. Básicamente, se encontró que el narrador entronca hábilmente eventos personales y de conocimiento público para justificar su lucha y la salvación de la patria. La presentación que hace el narrador de sí mismo es la de un héroe que está constantemente abocado a restituir un orden conservador y un pasado de felicidad bucólica.

An expected and manageable stage of its evolution, not an accident to avoid nor a reason for dismantling the set up work teams. No scapegoat no group, no regeneration group. All groups lives cyclically "the dethronement" of an earlier figure of leadership with some sort of sacrificial violence. This event closes a major conflict phase and inaugurates a renormalization group. It is therefore proposed to include itself as a phase in the generic models of group development.

    There is an increasing interest in screening instruments to detect intellectual disability (ID) in a quick and accurate way in mental health services as well as in the criminal justice system in order to provide appropriate support for people with undetected needs caused by ID. An instrument that has been proven to be useful in both settings is the Hayes Ability Screening Index (HASI). This study assessed the validity of the Dutch version of the HASI in persons with a substance abuse problem residing in mental health services, whether or not mandated to treatment by court order. The HASI was conducted along with the Wechsler Adult Intelligence Scale III as the criterion for validity to 90 participants. Additionally, the influence of psychiatric disorder and medication use on the HASI result was examined. A significant positive relationship was found between the two instruments, demonstrating convergent validity. Using a Receiver Operating Characteristic (ROC) curve analysis, the discriminative ability of the HASI with a cut-off score of 85 was found to be adequate, yielding in a good balance between sensitivity and specificity. The HASI was not distorted by the presence of the substance abuse problem or other psychiatric illnesses and medication did not influence the HASI scores in this study. These findings indicate that the HASI provides a time-efficient and resource-conscious way to detect ID in persons with a substance problem, thus addressing a critical need in mental health settings.

In order to develop the study, literature and academic articles have been consulted as a way to understand the multinationals and internationalization process, but mainly the relation between national culture distance and the choice of the market entry mode of companies willing to penetrate foreign markets, based on the research of Kogut and Singh (1988 and Brouthers and Brouthers (2001. The field study was developed in two main steps: the first one was an online survey designated to the 30 companies of the analyzed universe and two semi-structured interviews administrated to one German automaker and one auto parts company, aiming to go deeper into the information extracted from the questionnaire sent. The obtained results enabled the acknowledgment of a fundamental relation between the automakers presence in Brazil and the attraction of the auto parts companies to the Brazilian market, as well as the relation between the entrance of these companies and the economic cycle, in which Brazil was inserted at that moment. And finally confirm the relation between national culture distance, investment risk perception, and wholly-owned market entry mode choices.  Esta pesquisa tem o objetivo de analisar a relação estabelecida pela distância da cultura nacional entre Brasil e Alemanha e o modo de entrada escolhido por empresas alemãs ao penetrarem o mercado brasileiro, tendo como objeto de análise as empresas pertencentes ao setor automobilístico.

    Full Text Available The aim of this paper is to discuss a research project conducted between 2002-2005 in Porto Alegre, Brazil. The focus was exploring how a group of 90 students perceived media?s discourse ? especially television ? about ?youth.? Through the analysis of the discourse of both media and students, the research team selected a main theme for inquiry: the construction of the ?other? in the mass media and the perception of differences among these groups in relationship to social, economic, generational, racial, ethnic, and physical appearance dynamics. This research uses Foucaltian categories of analysis, specifically the concepts of normality, abnormality, and modes of subjectivity, and Hannah Arendt conceptualization about public and private spheres ? which allows for discussion of the multiple performances and images operating through media mechanisms. This work also uses other concepts like difference and alterity, follwoing Carlos Skliar studies.

    Full Text Available Bacteriocins are biologically active proteins or protein complexes that display a bactericidal mode of action towards usually closely related species. Numerous strains of bacteriocin producing Lactobacillus plantarum have been isolated in the last two decades from different ecological niches including meat, fish, fruits, vegetables, and milk and cereal products. Several of these plantaricins have been characterized and the aminoacid sequence determined. Different aspects of the mode of action, fermentation optimization and genetic organization of the bacteriocin operon have been studied. However, numerous of bacteriocins produced by different Lactobacillus plantarum strains have not been fully characterized. In this article, a brief overview of the classification, genetics, characterization, including mode of action and production optimization for bacteriocins from Lactic Acid Bacteria in general, and where appropriate, with focus on bacteriocins produced by Lactobacillus plantarum, is presented.Bacteriocinas são proteínas ou complexos protéicos biologicamente ativos que apresentam atividade bactericida contra espécies relacionadas.

Nesse estudo buscamos localizar no espaço e no tempo em quais condições históricas o sentimento de juventude apareceu para a sociedade. Em seguida, fazemos um minucioso levantamento da trajetória dessa nova categoria social nos mais diferentes períodos da história contemporânea. Chegamos, assim, ao século XX, momento em que as reuniões juvenis deixam de ser fatos isolados e adquirem conotações de manifestações verdadeiramente sociais.

    In vivo and in situ digestive characteristics of sainfoin (Onobrychis viciifolia L., a tannin-rich forage) and lucerne (Medicago sativa L., a tannin-free forage) were compared to evaluate the effects of condensed tannins (CT) and growth stage (vegetative v. early flowering) in experiment 1. In experiment 2, the hays of the two forages, harvested at early flowering, were compared. Ingestibility, organic matter digestibility (OMD) and nitrogen (N) retention were measured in sheep fed sainfoin and lucerne fresh forages and hays. The loss of dry matter (DM) and N from polyester bags suspended in the rumen, abomasum and small intestine was also measured using rumen fistulated sheep and other intestine fistulated sheep. Nitrogen content was lower in sainfoin than in lucerne. Content of CT in sainfoin decreased with growth stage (3.5 to 2.5 g CT/kg DM) and was lower for sainfoin hay (0.6 g CT/kg DM). Ingestibility and OMD did not differ between fresh-fed forage species. Total N tract digestibility in vivo was much lower for sainfoin than for lucerne fresh forages (mean value 0.540 v. 0.721, P forages. Nitrogen degradability in the rumen determined by the nylon bag technique (DegN) was lower for sainfoin than for lucerne when forages were studied both fresh (mean value 0.608 and 0.818, respectively) and as hays (0.631 and 0.767). The efficiency of forage N digestion (ENd) was higher for sainfoin at the vegetative stage. Compared with lucerne, sainfoin greatly increased the in situ estimate of forage N escaping the rumen but decreased its intestinal digestibility.

    Full Text Available En las ciudades, los espacios verdes públicos forman uno de los principales articuladores de la vida social, siendo lugares de encuentro e integración de los habitantes. La OMS considera que la superficie óptima mínima destinada a espacios verdes por habitante debe ser de 10 a 15 m2. No obstante, este indicador no garantiza la igualdad de acceso a todas las personas. Por ello, la superficie disponible y la ubicación de dichos espacios son factores fundamentales para asegurar esa igualdad y, por consiguiente, la calidad de vida urbana. Este trabajo centra su investigación en el análisis de los distintos modos de acceso y los patrones de uso de espacios verdes del Área Metropolitana de Mendoza, Argentina, con el fin de desarrollar un plan de inclusión de nuevos espacios verdes que aborden los ejes de cantidad y de igualdad de acceso peatonal. Con ese objetivo, se realizan encuestas a los usuarios, la cuales demuestran que la mayor parte de ellos llegan a estos sitios caminando, que existe relación entre el medio de transporte y la frecuencia con la que asisten a los espacios verdes, y que los radios de acción de dichos sitios varían entre 300 y 400m, dependiendo de la superficie del espacio.

O referencial teórico e metodológico fundamenta-se na perspectiva genealógica proposta por Michel Foucault, assim como em suas análises sobre os anormais e o poder psiquiátrico. No presente trabalho apresentaremos a análise do período de 1884 a 1937. Constata-se que as redes discursivas sobre as patologias nos territórios da infância e da adolescência permitem identificar algumas descontinuidades e continuidades: descontinuidade do ponto de vista dos diagnósticos encontrados, mas continuidade no que se refere às estratégias de exclusão social

    The potential for acid-detergent insoluble ash (ADIA), alkaline-peroxide lignin (APL), and acid-detergent lignin (ADL) to predict fecal output (FO) and dry matter digestibility (DMD) by cattle offered bermudagrass [Cynodon dactylon (L.) Pers.] hays of different qualities was evaluated. Eight ruminally cannulated cows (594 ± 35.5 kg) were allocated randomly to 4 hay diets: low (L), medium low (ML), medium high (MH), and high (H) crude protein (CP) concentration (79, 111, 131, and 164 g CP/kg on a DM basis, respectively). Diets were offered in 3 periods with 2 diet replicates per period and were rotated across cows between periods. Cows were individually fed 20 g DM/kg of body weight in equal feedings at 08:00 and 16:00 h for a 10-d adaptation followed by a 5-d total fecal collection. Actual DM intake (DMI), DMD, and FO were determined based on hay offered, ort, and feces excreted. These components were then analyzed for ADL, APL, and ADIA concentration to determine marker recovery and marker-based estimates of FO and DMD. Forage DMI was affected by diet (P = 0.02), and DMI from MH and H was greater (P forages. Results from such studies may be used to develop improved equations to predict energy values of forages based on the relationship of dietary components to digestibility across a wide range of forages.

The trial was divided in two periods of 14 days each. Diet (DM=53.7% was formulated in order to assure the nutritional requirements of cows producing 24 kg/d of milk (crude protein=14.4% DM; NDF=40.9% DM; milk FU=0.88/kg DM and additional amounts of concentrates were distributed using automatic feeders. Four TMR samples were collected daily (7.00 am, 10.00 am, 1.00 pm, 4.00 pm for six days during each experiment period for a total number of 48 feed samples. Each feed sample was subjected to the estimation of the particle size distribution using the separator of Pennsylvania State University composed of two sieves (diameters of 19 and 8 mm and a collector on the bottom, and to the determination of the chemical composition. Changes of all three particle size fractions for TMRs were observed during the day with distributions of the TMR both once and twice daily. With the once daily distribution, the large particles fraction increased linearly (P<0.001 from 19.7 to 23.4, 32.2, and 35.1%, while the finest particle fraction decreased (from 60.1 to 58.3, 50.0, 47.8%.

    Pine (Pinus morrisonicola Hay, PM) needles have been used as folk medicine for their antihypertension and lipid-lowering effects. As supercritical fluid extraction (SFE) is considered an ideal technique for the extraction of essential oil from plant materials, the present work investigated the optimal SFE conditions and the protective effects of different resulting fractions of PM needles on lipid peroxidation and foam cell production in macrophages. Nine PM needle extracts (PME1-9) were obtained in 1%-4% yields using different SFE conditions, of which PME1 had the lowest yield (1.1%) and PME3 the highest (3.9%). PME3 exhibited lower cytotoxic effects and stronger inhibition of lipid peroxidation and formation of foam cell in RAW 264.7 macrophages than those of other PME extracts. PME3-1 purified from PME3 by column and thin layer chromatography inhibited LDL oxidation more effectively than did PME3 in a cell-free system oxidized by Cu(2+). PME3-1 dose-dependently (25-100 μg/mL) decreased conjugated diene levels and foam cell formation induced by ox-LDL. GC/MS analyses revealed that 1-docosene, neophytadiene, and methyl abietate were increased 5.2-, 1.7- and 4.3-fold in PME3-1 relative to PME3. A new hydrocarbon compound, cedrane-8,13-diol, was identified in PME3-1. Overall, the present study demonstrates the optimal extraction conditions of SFE of PM and identifies the most potent antioxidant fractions and possible active compounds in PM.

    A study was done to evaluate banana (Musa paradisiaca) as a forage (leaves and pseudo-stems) for feeding Ovin Martinik lambs (OMK), with the aim to test its impact on carcass quality. Forty four intact OMK male were used after weaning with an initial mean live weight of 14.4 (+/- 3.3) kg, reared in individual pens. Animals were offered either Dichantium hay (control diet, Dh) or cut chopped leaves and pseudo-stems of banana (experimental diet, Blps). They were fed 200-250 g x d(-1) of commercial concentrate. Lambs were slaughtered according to 3 classes of slaughter weight (SW): SW20, SW23 and SW26. Growth and carcass performances of both groups were not significantly different, 77 vs. 81 g x d(-1) and 42% vs. 43% hot carcass yield, for Dh vs. Blps, respectively. There was a significant (P < 0.05) decrease (31.0 vs. 29.7%) for the dry matter content of the shoulder for lambs fed the banana diet. However, there was no effect observed for the other chemical component (CP, lipid and mineral 585, 317 and 95 g x kg(-1) DM, respectively). The shoulder (20% of the carcass whatever the SW) was precocious as demonstrated by the allometry coefficient relative to carcass weight (0.894) significantly (P < 0.01) less than 1. It was concluded that, the use of Blps had no significant effect on growth, carcass weights and yields of the OMK lambs, irrespective of the class of the slaughter weight. From these initial results, the use of banana foliages and pseudo-stems could be recommended as sources of forages.

Different levels [0%, 5%, 10%, 15% and 20% of dry matter (DM)] of the medicinal plants were included using alfalfa hay (AH) as a basal substrate at different incubation times (12, 18, 24 and 48 h). Total phenolic components of AH, FS and AR were 5.9, 10 and 8.3 g/kg DM, whereas total tannins were 0.4, 3.8 and 1.5 g/kg DM, respectively. Corresponding values for saponins were 10.4, 27.3 and 40.3 g/kg DM. Fenugreek seed increased (pAsparagus root also increased (p<0.05) in vitro OM digestibility and decreased (p<0.05) CP digestibility at different incubation times. Neutral detergent fibre digestibility was increased (p<0.05) by the addition of AR or FS at low levels, but decreased (p<0.05) noticeably by increasing level of two plants in the basal substrate. Ammonia-N concentration was markedly reduced (p<0.05) by the addition of AR at different incubation times, and this reduction was accompanied by the decrease in CP digestibility. True DM degradability and partitioning factor (ratio of substrate DM truly degraded to gas volume produced at different times of incubation) were increased, and total volatile fatty acid concentration and total gas production were decreased (p<0.05) with the addition of FS (at 10% and 15% DM levels) or AR (at 5%, 10% and 15% DM levels) at different incubation times. Results suggest that FS and AR may have potential as feed additives to increase the efficiency of nutrients' utilization, particularly of nitrogen in ruminant diets. © 2012 Blackwell Verlag GmbH.

    The State of Alaska’s Strategic and Critical Minerals (SCM) Assessment project, a State-funded Capital Improvement Project (CIP), is designed to evaluate Alaska’s statewide potential for SCM resources. The SCM Assessment is being implemented by the Alaska Division of Geological & Geophysical Surveys (DGGS), and involves obtaining new airborne-geophysical, geological, and geochemical data. As part of the SCM Assessment, thousands of historical geochemical samples from DGGS, U.S. Geological Survey (USGS), and U.S. Bureau of Mines archives are being reanalyzed by DGGS using modern, quantitative, geochemical-analytical methods. The objective is to update the statewide geochemical database to more clearly identify areas in Alaska with SCM potential. The USGS is also undertaking SCM-related geologic studies in Alaska through the federally funded Alaska Critical Minerals cooperative project. DGGS and USGS share the goal of evaluating Alaska’s strategic and critical minerals potential and together created a Letter of Agreement (signed December 2012) and a supplementary Technical Assistance Agreement (#14CMTAA143458) to facilitate the two agencies’ cooperative work. Under these agreements, DGGS contracted the USGS in Denver to reanalyze historical USGS sediment samples from Alaska. For this report, DGGS funded reanalysis of 670 historical USGS sediment samples from the statewide Alaska Geochemical Database Version 2.0 (AGDB2; Granitto and others, 2013). Samples were chosen from the northeastern Alaska Range, in the Healy, Mount Hayes, Nabesna, and Tanacross quadrangles, Alaska (fig. 1). The USGS was responsible for sample retrieval from the National Geochemical Sample Archive (NGSA) in Denver, Colorado through the final quality assurance/quality control (QA/QC) of the geochemical analyses obtained through the USGS contract lab. The new geochemical data are published in this report as a coauthored DGGS report, and will be incorporated into the statewide geochemical

    Two trials were conducted to test the hypotheses that (i) feeding small amount of a tanniniferous shrub foliage (Acacia cyanophylla Lindl., acacia) increases the proportion of rumen undegradable protein, and consequently benefits growth performance in Barbarine lamb; and (ii) such positive effect depends on the timing of feeding tannin source (i.e. acacia) relative to protein source (soya bean meal, SBM). Total (TT) and condensed tannin (CT) concentrations in air-dried acacia leaves used in this study averaged 29 g tannic acid and 48 g leucocyanidin equivalents per kg dry matter (DM), respectively. In trial 1, rumen fistulated ewes received oaten hay (hay) ad libitum and 200 g SBM (D1), D1 and 100 g acacia fed with the SBM (D2, mixed strategy) or as D2, but the SBM fed 1 h later than acacia when acacia was consumed completely (D3, sequential strategy). Hay intake, diet digestibility, rumen fermentation parameters (pH, ammonia nitrogen (NH 3 -N) and total volatile fatty acids) and in situ degradation of SBM nitrogen were similar between D1 and D2 (P > 0.05). However, the sequential strategy (D3) resulted in efficient use of N as reflected by the decrease of crude protein digestibility (CPD), plasma urea, NH 3 -N concentration and in situ degradation of SBM nitrogen. In trial 2, four groups each of six Barbarine lambs (initial LW 35.3 ± 3.7 kg) received for 90 days: hay ad libitum and 200 g SBM (D1), D1 and 20 g polyethylene glycol (PEG, MW 4000) mixed with SBM (D2), D1 and 100 g acacia with the SBM fed 1 h later when acacia was completely consumed (sequential strategy) (D3) or D3 and 20 g PEG fed with the SBM (D4). Polyethylene glycol was here used to deactivate tannins. Hay intake and DM, organic matter and neutral detergent fibre digestibility were similar among dietary treatment (P > 0.05). However, supplementing lambs with SBM and acacia without PEG (D3) resulted in a significant decrease (P 0.05). However, those supplemented with acacia without PEG (D3) had

Hay intake, diet digestibility, rumen fermentation parameters (pH, ammonia nitrogen (NH{sub 3}-N) and total volatile fatty acids) and in situ degradation of SBM nitrogen were similar between D1 and D2 (P > 0.05). However, the sequential strategy (D3) resulted in efficient use of N as reflected by the decrease of crude protein digestibility (CPD), plasma urea, NH{sub 3}-N concentration and in situ degradation of SBM nitrogen. In trial 2, four groups each of six Barbarine lambs (initial LW 35.3 {+-} 3.7 kg) received for 90 days: hay ad libitum and 200 g SBM (D1), D1 and 20 g polyethylene glycol (PEG, MW 4000) mixed with SBM (D2), D1 and 100 g acacia with the SBM fed 1 h later when acacia was completely consumed (sequential strategy) (D3) or D3 and 20 g PEG fed with the SBM (D4). Polyethylene glycol was here used to deactivate tannins. Hay intake and DM, organic matter and neutral detergent fibre digestibility were similar among dietary treatment (P > 0.05). However, supplementing lambs with SBM and acacia without PEG (D3) resulted in a significant decrease (P < 0.001) of CPD (0.664 versus 0.597, respectively for D1 and

    Oil and natural gas industry prospects for 1997 were reviewed. By way of providing the foundation for a very favorable forecast, a wide range of indicators of a banner year in 1996 were assembled and provided in tabular form. Some 28 tables of statistical data provide insight into the reasons for an optimistic forecast for 1997. Statistics on oil and gas production, industry expenditures, exploratory well completions, costs per barrel of oil, estimates of supply and demand for petroleum products, gas liquid production, petrochemical and fertilizer production, sulfur production, drilling statistics, natural gas sales, gross production revenues and land sales, all attest to a record year in 1996, and provide reasons for a rosy outlook for 1997. 28 tabs

    Full Text Available Muitos componentes das modernas aeronaves estão sendo manufaturados em compósitos poliméricos. Laminados de resina epóxi modificada reforçada com fibras de carbono contínuas são empregados em estruturas primárias e secundárias para reduzir o peso e melhorar o desempenho operacional. Porém, se ocorrer uma falha circunstancial, o processo de fratura desses laminados é complexo e pode envolver mecanismos de danos interlaminares. A delaminação é a descontinuidade interlaminar que pode se propagar de forma catastrófica com a aplicação de cargas mecânicas. O ensaio de corpos de prova denominado de Double Cantilever Beam (DCB é o método mais utilizado para determinar a tenacidade à fratura em Modo I de compósitos estruturais. Neste trabalho, amostras preparadas de um laminado de tecido bidirecional, estilo plain weave, foram submetidas ao carregamento estático de delaminação em Modo I, à temperatura ambiente. A análise fractográfica das superfícies delaminadas foi realizada por microscopia eletrônica de varredura. Os resultados mostram que o processo de fratura se inicia nas bolsas de resina após um inserto de Teflon® e se propaga ao longo das regiões ricas em resina posicionadas nos interstícios de entrelaçamento das mechas da trama e da urdidura. Os principais aspectos fractográficos revelados são identificados, documentados e discutidos neste trabalho.Many components of modern aircrafts are now manufactured from polymer composites. Reinforced laminates with continuous carbon fibers and modified epoxy resin are employed in primary and secondary structures to reduce weight and improve the aircraft performance. However, if a circumstantial failure happens, the complex fracture process of the laminates may involve interlaminar damage mechanisms. The delamination is the interlaminar discontinuity which may propagate catastrophically with the application of mechanical loads. The Double Cantilever Beam (DCB is the most

O objetivo do presente trabalho foi comparar fontes e modos de aplicação de Zn à cultura do milho. O experimento foi desenvolvido em casa de vegetação, em vasos de polietileno com capacidade de 10 litros, utilizando-se amostras de um Latossolo Vermelho-Escuro de textura média. Aplicou-se calcário para se atingir 70% de saturação do solo por bases. Os tratamentos consistiram da aplicação de zinco como óxido, sulfato, EDTA e lignossulfonado, na semente (90 g ha-1, no sulco de semeadura (5,3 kg ha-1 e incorporado (5,3 kg ha-1. As plantas foram colhidas 45 dias após a emergência. A aplicação de zinco via semente é eficiente no fornecimento de Zn para o crescimento das plantas até os 45 dias. A incorporação, independentemente da fonte, e o zinco aplicado como EDTA e lignossulfonado proporcionam maior disponibilidade do nutriente ao milho. O crescimento do sistema radicular é prejudicado quando há muito Zn disponível na zona de crescimento. A dose de 5,3 kg ha-1 de zinco como EDTA ou lignossulfonado, quando aplicada no sulco de semeadura, é fitotóxica ao milho.

    This study measured the effects of including 5% NaOH-treated corn straw (T-CS) as a substitute for 15% wheat hay in the control total mixed ration (TMR) of lactating cows on performance, digestibility, and rumen microbial profile. Two groups of 21 cows each, similar in initial performance, were fed individually 1 of the 2 TMR examined. Voluntary dry matter intake of cows fed the control TMR was 4.3% higher than that of the T-CS cows, but in vivo dry matter and organic matter digestibilities of both groups were similar. Crude protein digestibility was higher in the control cows but digestibility of neutral detergent fiber polysaccharides (cellulose and hemicelluloses) was higher in the T-CS TMR. This was followed by 4.6% reduction in rumination time of the T-CS group. A slightly higher milk yield was observed in the control cows compared with the T-CS group; however, milk fat and milk protein content were higher in cows fed the T-CS TMR. This was reflected in 1.3% increase in energy-corrected milk yield and 5.34% increase in production efficiency (energy-corrected milk yield/intake) of the T-CS cows compared with the control. Welfare of the cows, as assessed by length of daily recumbence time, was improved by feeding the T-CS TMR relative to the control group. As a whole, the rumen bacterial community was significantly modulated in the T-CS group in the experimental period compared with the preexperimental period, whereas the bacterial community of the control group remained unchanged during this period. Out of the 8 bacterial species that were quantified using real-time PCR, a notable decrease in cellulolytic bacteria was observed in the T-CS group, as well as an increase in lactic acid-utilizing bacteria. These results illustrate the effect of T-CS on the composition of rumen microbiota, which may play a role in improving the performance of the lactating cow.

    The provision of NaCl, according to current recommendations, to horses in moderate work has been shown to induce immediate postprandial acidosis. The present study aimed to clarify whether this NaCl induced acidosis i) persists beyond the immediate postprandial period, and ii) is still present after a 2 week adaptation period. Six adult warmblood mares in moderate work received daily 1.00 kg hay per 100 kg body weight (bwt) only together with 0.64 kg unprocessed cereal grains/100 kg bwt.d as fed basis. Using a 3x3 Latin Square, either 0 (NaCl-0), 50 (NaCl-50) or 100 (NaCl-100) g NaCl/d were fed together with the concentrates in two equal doses for 3 weeks. During the final week, a mineral digestibility trial was undertaken. The middle sodium and chloride intake (NaCl-50) at least met the most common recommendations for moderate work. Morning (7:00 AM) urine and venous blood samples were collected on days 0, 1-4, 8, and 15, and analysed for pH, acid-base status, creatinine and electrolyte concentrations. Fractional electrolyte clearances (FC) were determined. Mean apparent sodium digestibility ranged between 60-62% whereas chloride digestibility was consistently above 94%. Supplementing 100 g but not 50 g of NaCl resulted in significant reduction of blood pH and base excess as well as urinary pH and urine acid excretion. Both 50 g and 100 g NaCl supplementation caused a significant reduction in base and net acid-base excretion, urine density and potassium concentration, but increased urine sodium concentration and the FC of sodium and chloride (P salt doses is excreted renally. The above effects of NaCl supplementation persisted over the 2 week measurement period. Results suggest that feeding 100 g NaCl to moderately exercising horses results in mild metabolic acidosis, whereas feeding 50 g according to current recommendations resulted in compensated acidosis.

    This report presents the geologic framework, hydro­stratigraphy, and ichnology of the Trinity and Edwards Groups in the Blanco, Payton, and Rough Hollow 7.5-minute quad­rangles in Blanco, Comal, Hays, and Kendall Counties, Texas. Rocks exposed in the study area are of the Lower Cretaceous Trinity Group and lower part of the Fort Terrett Formation of the Lower Cretaceous Edwards Group. The mapped units in the study area are the Hammett Shale, Cow Creek Limestone, Hensell Sand, and Glen Rose Limestone of the Trinity Group and the lower portion of the Fort Terrett Formation of the Edwards Group. The Glen Rose Limestone is composed of the Lower and Upper Members. These Trinity Group rocks con­tain the upper and middle Trinity aquifers. The only remaining outcrops of the Edwards Group are the basal nodular member of the Fort Terrett Formation, which caps several hills in the northern portion of the study area. These rocks were deposited in an open marine to supratidal flats environment. The faulting and fracturing in the study area are part of the Balcones fault zone, an extensional system of faults that generally trends southwest to northeast in south-central Texas.The hydrostratigraphic units of the Edwards and Trinity aquifers were mapped and described using a classification system based on fabric-selective or not-fabric-selective poros­ity types. The only hydrostratigraphic unit of the Edwards aquifer present in the study area is hydrostratigraphic unit VIII. The mapped hydrostratigraphic units of the upper Trinity aquifer are (from top to bottom) the Camp Bullis, upper evaporite, fossiliferous, and lower evaporite which are interval equivalent to the Upper Member of the Glen Rose Limestone. The middle Trinity aquifer encompasses (from top to bottom) the Lower Member of the Glen Rose Limestone, the Hensell Sand Member, and the Cow Creek Limestone Member of the Pearsall Formation. The Lower Member of the Glen Rose Limestone is subdivided into six informal hydro

    In a first of two experiments, twenty yearling male Pedi goats weighing 21.3 +/- 0.5 kg live weight were used in a 37-day study in a 2 (levels of PEG 4000) x 2 (levels ofAcacia) Factorial arrangement in a Completely Randomised Design to determine the effect of the level of Acacia nilotica leaf meal supplementation plus 23 g polyethylene glycol 4000 on diet intake and digestibility, and growth rate of Pedi goats fed ad libitum Buffalo grass hay. Acacia nilotica leaf meal contained high amounts of total phenolics (2.04% DM) and low amounts of condensed tannins; both extracted (0.37% DM) and unextracted (1.83% DM). Supplementation with PEG 4000 increased (P < 0.05) crude protein intake as the level of Acacia nilotica leaf meal increased from 80 to 120 g. Similarly, treatment with PEG 4000 improved (P < 0.05) DM, OM and CP digestibilities when compared to 80 g Acacia nilotica leaf meal. Supplementation with PEG 4000 resulted in an increase (P < 0.05) in blood urea concentrations. Polyethylene glycol 4000 has the potential to improve the feeding value of A. nilotica leaf meal and can, therefore, be used in the feeding systems for ruminant animals. The second experiment determined the effect of A. nilotica leaf meal supplementation on in vitro digestibility of the diets similar to the actual ratios of the first experiment. Level of A. nilotica leaf meal supplementation plus 23 g PEG 4000 supplementation improved (P < 0.05) in vitro DM, OM and CP digestibilities where 120 g A. nilotica leaf meal was supplemented. Similarly, 23 g PEG 4000 supplementation also improved (P < 0.05) in vitro CP digestibility where 80 g A. nilotica leaf meal was supplemented. In vivo DM and OM digestibilities were best predicted from in vitro DM and OM digestibilities while in vivo CP was explained by in vitro OM and CP digestibilities. It is, therefore, concluded that in vitro DM and OM digestibilities have good capacity to predict in vivo DM and OM digestibilities while OM and CP

    This study evaluated the effects of particle size (PS) and dietary level of alfalfa hay (AH) on rumen fermentation parameters, blood metabolites, eating behavior, and growth performance in dairy calves during transition from liquid to solid feed. Sixty newborn dairy calves (41 ± 2.5,kg of body weight) were used in a 2 × 2 factorial arrangement with the factors dietary AH level (medium, 12.5%, or high, 25%, on DM basis) and PS (fine = 1mm or medium = 3mm, as geometric means) of AH. Hence, the dietary treatments were (1) medium level of AH with fine PS (M-FPS), (2) medium level of AH with medium PS (M-MPS), (3) high level of AH with fine PS (H-FPS), and (4) high level of AH with medium PS (H-MPS). Particle size of AH did not affect total DMI (TDMI) during the preweaning period, although TDMI was greater for calves fed MPS than in those fed FPS during the postweaning and overall periods. Calves fed MPS spent more time eating solid feed and ruminating and less time on nonnutritive oral behaviors compared with FPS calves. The dietary level of AH did not affect behavioral parameters. Average daily gain of calves was not affected by dietary treatment before weaning. During the postweaning and overall periods, average daily gain was greater in calves fed MPS than in those fed FPS at the 25% AH level, but this effect was absent with 12.5% AH. Furthermore, the rumen pH values on d 35 and 70 of the study were greater for MPS than for FPS, regardless of the dietary level of AH. Effects of AH level, PS, and their interaction did not affect blood glucose concentrations in developing calves. These results indicate that feed intake, feeding behavior, rumen fermentation parameters, and blood β-hydroxybutyrate concentration may be affected by rations differing in forage PS; thus, providing calves with MPS can improve calf performance and reduce their nonnutritive oral behaviors.

    The present study was conducted to determine the optimum age of Holstein dairy calves for an effective inclusion of alfalfa hay (AH) in starter feed on performance, apparent digestibility and feeding behavior. A total of 40 Holstein dairy calves (20 female and 20 male) were used in a completely randomized design in which calves were randomly assigned to one of four different dietary treatments including control (CON) calves fed starter feed without any forage and three treatments consisting of the same starter feed plus 15% chopped AH fed when calves were at the 2nd (AH2), 4th (AH4) or 6th (AH6) week of age. Calves were individually housed and bedded with sand that was replaced every other day. Feed and water were available ad libitum throughout the experiment. Calves were fed milk at 10% of birth BW twice daily until d 57. The study concluded when calves were 73 days old. Starter intake was recorded daily and BW was measured weekly. Data were analyzed as a complete randomized design by MIXED procedures of SAS. Results demonstrate that calves receiving AH treatments numerically consumed more starter feed (0.62 v. 0.78, 0.71 and 0.65 kg/day for CON, AH2, AH4 and AH6, respectively) and had greater average daily gain (ADG) compared with CON (0.48 v. 0.57, 0.49 and 0.49 kg/day for CON, AH2, AH4 and AH6), although the significant difference was observed only between AH2 and CON. Among AH treatments, calves in AH2 had better performance than AH6 in several cases including starter intake, ADG. No detectable differences were observed, however, in apparent dry matter, organic matter or CP digestibility among treatments. Ruminal pH and NH3 concentrations, measured on weeks 4, 6, 8 and 10, were lower for calves fed CON compared with other treatments, with ammonia concentrations decreasing over time. Calves in the AH treatments spent more time eating and ruminating compared with CON. Calves fed CON, however, spent more time on laying down compared with other treatments

    Full Text Available The objective was to evaluate the effect of a quantitative feed restriction on the voluntary intake of hay, the performance of laying hens, and on egg quality. A total of 150 Hisex Brown laying hens at 51-weeks old were distributed into five treatments and five replications of six hens each. The treatments consisted of control, with supply of 100 g of feed bird-1 day-1 without hay; and the others consisting of a feed restriction of 5, 10, 15 and 20% of the diet offered to the birds in the control treatment, along with an ad libitum supply of cunhã hay (CH, leucaena leaf meal (LLM and tifton hay (TH. A linear increase was found in the hay intake with increasing level of dietary restriction. However, egg production, egg weight, egg mass and feed conversion decreased linearly. Yolk color was affected by the treatments. Birds with 20% feed restriction presented the greatest yolk pigmentation. In conclusion, laying hens can be subjected to a 5% feed restriction with supply of hay ad libitum.O objetivo da pesquisa foi avaliar o efeito da restrição alimentar sobre a ingestão voluntária de feno, o desempenho das aves e a qualidade dos ovos. Foram utilizadas 150 poedeiras da linhagem Hisex Brown com 51 semanas de idade. As aves foram distribuídas em cinco tratamentos com cinco repetições de seis aves cada. O tratamento controle consistiu no fornecimento de 100 g de ração ave-1 dia-1 sem oferta de feno e os demais na oferta de 95, 90, 85 e 80 g de ração ave-1 dia-1, que corresponderam, respectivamente, às restrições de 5, 10, 15 e 20% da quantidade de ração, com o fornecimento de feno à vontade. Foram utilizados os fenos de cunhã, das folhas de leucena e de tifton. Com o aumento no nível de restrição, houve aumento no consumo diário de feno, redução na produção, na massa de ovo, no peso médio das aves e piora na conversão alimentar. Em relação às características de qualidade dos ovos, apenas a coloração da gema variou

    Full Text Available Com finalidade de melhor conhecimento da forma indeterminada da doença de Chagas os autores realizaram estudo anatomopatólogico sistematizado de trinta corações de chagásicos assintomáticos falecidos de modo violento. Demonstram que nos portadores da forma em questão da tripanossomiase cruzi o coração e acometido por lesões da mesma natureza, porém de intensidade muito menor do que as observadas em chagásicos crônicos que falecem subitamente ou após periodo variável de insuficiência cardíaca. Baseados em seus achados e em outros dados da literatura, concluem que a infecção chagásica, sem inflamação do coração, se ocorre, é rara. Tecem ainda considerações a respeito do significado das lesões observadas no sistema nervoso autônomo intracardíaco no sistema de condução e sobre a gênese formal da cardite chagásica crônica humana.With the purpose of better knowledge of the indeterminate form of Chagas's disease the authors carried out a systematized anatomopathological study of thirty hearts from symptomatic chagasics who had a violent death. In this specific form of the trypanosomiasis cruzi the hearts show lesions of the same nature but much less intense as those observed in chronic chagasics who had a sudden death or died after cardiac failure. Based on theses findings and on data from literature, we conclude that chagasic infection without a cardiac inflammatory process, if it occurs, is very rarely only. Also some comments are made upon the meaning of the lesions observed in the intra-cardiac autonomic nervous system, in the conduction system and on the formal origin of the human chronic chagasic carditis.

Su punto de partida fue la pregunta, Desde la perspectiva de los jóvenes "¿Cuales son aquellos aspectos de la dinámica escolar que se constituyen en facilitadores o en obstáculos de la permanencia (con sentido en la escuela?". Desde un enfoque cualitativo, que asume la importancia de la experiencia subjetiva de los individuos en la construcción del mundo social, la investigación construyó un acercamiento progresivo a la voz y la mirada de los actoresde este proceso. Se han desarrollado entrevistas biográfico narrativas sobre trayectorias escolares, entrevistas en profundidad y grupos focales incluyendo diferentes técnicas de recolección de información como la foto-elucidación. El universo de este estudio estuvo conformado por jóvenes del conurbano bonaerense que dejaron de participar de la experiencia escolar formal entre los años 2006 y 2008. Entre los resultados más relevantes de la investigación, podemos señalar la percepción de una escuela que pone en marcha modos de exclusión "instrumentales", la naturalización de las prácticas escolares, la identificación por parte de los jóvenes de "incidentes críticos" que los alejan de la escuela y el lugar que ocupa en la vida de los jóvenes el grupo de pares como factor que contribuye a la permanencia en la escuela pero que al mismo tiempo es significado como obstáculo que impide el aprendizaje y contribuye a la exclusión.

    Full Text Available Misturas com borracha são freqüentemente usadas para se conseguir o balanço das propriedades desejadas e também, em alguns casos, a redução de custos. As misturas elastoméricas são normalmente sistemas multifásicos e a distribuição dos aditivos entre as fases não é necessariamente uniforme. Neste trabalho, o polibutadieno (BR foi misturado ao elastômero de butadieno-estireno (SBR na proporção 1:1 em peso. As composições foram preparadas utilizando um misturador de rolos, segundo a norma ASTM D3182, sendo que a incorporação dos aditivos foi realizada de quatro formas diferentes. Após a avaliação das propriedades reométricas e a vulcanização, foram estudadas as propriedades mecânicas para cada composição, avaliadas de acordo com as normas ASTM específicas para cada ensaio. Os resultados mostram que os diferentes modos de preparo de uma mesma formulação podem provocar mudança significativa nas propriedades mecânicas de misturas envolvendo essas duas borrachas. No caso das misturas BR/SBR estudadas, as propriedades apresentaram valores intermediários aos das borrachas isoladas.Rubber blends are frequently prepared to give a balance of the desired properties and, in some cases, reduction of cost as well. Elastomeric mixtures are usually multiphase systems and the dispersion of the additives may not be uniform throughout the phases. In this work, polybutadiene rubber (BR was mixed with polybutadiene-styrene rubber (SBR in a 50:50 w/w ratio. The compositions were prepared in a two-roll mill, according to ASTM D3182, and the incorporation of the ingredients was carried out according to four different modes. After the determination of the rheometric properties and the vulcanization of the compounds, mechanical properties were evaluated according to specific ASTM procedures. The results show that the mechanical properties may be altered by changing the procedure to prepare a given formulation. In the case of BR

    Full Text Available Diversos autores como Capra (1996 e Kempf (2010 apresentam novas propostas para um mundo cada vez mais ávido por transformar e consumir os bens materiais que a natureza reserva para a manutenção da vida. É diante de crises ecológicas e da devastação dos recursos naturais que os autores propõem romper com o paradigma predominante, que tem como modelo econômico e político o uso cada vez mais perverso sobre a natureza, transformada em valor de troca. Nesse sentido, o sistema capitalista é incapaz de garantir os bens materiais às futuras gerações, sendo apontado pelos autores que seja necessário romper-se com a lógica do capital e inventar ou propor novos valores sociais antes que um cataclismo ambiental coloque o mundo em crise profunda. A questão que está no centro do debate sobre o uso da natureza pelo capital consiste em saber identificar como a cultura individualista opera nos indivíduos, cada vez mais ávidos pela competição desenfreada promovida pelo mercado. Dessa forma, realizou-se uma reflexão sobre o emprego do discurso de desenvolvimento sustentável dentro do sistema capitalista, entendendo que a acumulação exponencial sem fim (HARVEY, 2014 do capital se pautará numa nova captura de renda sobre os países pobres. Trata-se da imposição, por meio de normas ambientais, de novas inovações nos meios de produção e nas mercadorias que privilegiem a menor degradação do meio ambiente, mas que, por outro lado, países pobres não têm volumes grandes de capital acumulado, o que obriga a burguesia e os Estados nacionais a se endividarem na compra desses novos meios de produção. Daí o problema do discurso e da defesa do desenvolvimento sustentável no modo de produção capitalista.

La perspectiva multimodal sobre la comunicación considera el potencial semiótico de los distintos recursos que son entrelazados en el discurso para crear significados en contexto. Esta investigación (Fondecyt 1130684 se lleva a cabo siguiendo un enfoque multimodal, la lingüística sistémica funcional y la teoría de la valoración, para explorar las opciones semióticas de tres estudios de caso: profesores de historia enseñando a sus estudiantes de 1° año de educación secundaria. El corpus está constituido por el registro audiovisual de tres clases introductorias de la misma unidad curricular: la Segunda Guerra Mundial. Luego de un análisis multimodal del discurso, los hallazgos nos indican que los profesores optan por distintas combinaciones de medios y modos semióticos para enseñar el mismo contenido. Respecto del conocimiento disciplinar, el despliegue de mapas, listados y cronologías sobre el pizarrón en interacción con la lengua oral aportan a la construcción de la dimensión temporal y espacial, mientras que recursos visuales, como fotografías y videos, aportan a la evidencialidad. Entre tanto la lengua oral construye el aprendizaje de la causalidad en historia, potenciando la afiliación de los estudiantes a la interpretación propuesta de los procesos históricos. Al mismo tiempo, el recurso lingüístico es el soporte mediante el cual el propio profesor se representa a sí mismo en el discurso pedagógico como un narrador con distintos grados de subjetividad.

    The objective of this study was to investigate the effects of substituting sweet potato [Ipomoea batatas (L) Lam] vines for concentrate on growth performance, digestibility, and carcass characteristics. Thirty yearling bucks (15.3 ± 1.64 kg) were assigned into six treatments in a randomized complete block design: natural grass hay alone (T1) or supplemented with 100 % sweet potato vines (SPV) (T2), 65 % SPV + 35 % concentrate (T3), 35 % SPV + 65 % concentrate (T4), and 100 % concentrate (T5) on dry matter (DM) basis. Supplemented goats (T2, T3, T4, and T5) consumed higher (p goats (349 g/day). The crude protein (CP) intake (32.0, 48.6, 54.7, and 69.2 g/day) increased with increasing levels of the concentrate in the diet for T2, T3, T4, and T5, respectively. The DM digestibility in T2, T3, T4, and T5, respectively, was higher (P goats lost weight (-19.5 g/day). Slaughter weight, empty body weight, hot carcass weight, dressing percentage, rib-eye muscle area, and total edible offals were higher (P goats compared with nonsupplemented ones. Therefore, it could be concluded that sweet potato vine can replace the conventional concentrate and could be fed with poor quality hay to prevent body weight loss of animal in the absence of other feed supplements.

    The aim of this work was to evaluate the energy balance and the sustainability in the hay production through seven years data from a Intensive System of Milk Production, located in the region of Coronel Pacheco/MG Brazil. To the energy matrix determination, the categories of direct and indirect energy were considered. The energy inputs occurred in the implanting and establishing of the crop were distributed in the years considered as useful life. The direct energy, relative to the inputs, had larger participation that the indirect one, being the percentiles found of 93.05 and 6.95, respectively. The main consumer of indirect energy was the tractor, which turns on all the implements, followed by the irrigation system. The estimated energy efficiency by the process was of 3.19. Most of the used direct energy was that derived from fossil resources, in the form of fuel (diesel). The use of organic fertilizer, of poultry litter, promoted a relative reduction in the consumption of energy originated from fertilizer derived from fossil resources. With the obtained results, it was concluded that, despite of the several sources of energy consumption, the production of alfalfa hay is sustainable and efficient in the energy conversion. (author)

    Full Text Available The article presents results of analysis made on internship reports at Educational Management in Pedagogy courses, aiming to capture facets of the relationships established between teachers, students, staff and management team, in two São Paulo state public schools from the periphery of the Metropolitan Region, São Paulo, Brazil, and then show modes to organize educational work. We discuss the forms as trainees have identified actions that favor or not the collective participation in decision-making, from the observation they done about dynamics of the relationships were established among individuals, in the institutions where the internship was done. Three strands of analysis were structured: profile of the management teams; relationship from management with teachers; and administration and inclusion, taking as reference Blase (2000. According to the analysis, it was realized that the organization of educational work in both schools could be identified either with a more democratic manner, which implies the involvement of various school actors, and sometimes with a more centralized way of envisage the many problems that arose every day, revealing this management was not representative of the group. Those profiles explain ways to establish relationships at school, favoring or not the participation in decision-making moments. Also indicate that there are no pure models of school management. These issues need to be stressed in order to question the existing power relations in schools, associated with the reality social, that is marked by contradictions.

Nessa nova dinâmica desenvolveu-se a terceirização, na qual as empresas tomadoras repassam às empresas prestadoras e especialistas, as atividades que, supostamente, não fazem parte dos processos críticos do negócio, o core business; com pressupostos de redução de custos e aumento de eficiência. A forma de produzir bens ou serviços é resultado da conjunção de recursos materiais, tecnologia e força de trabalho, o que permite ampla gama de configurações da organização. Este artigo apresenta um estudo de caso, cuja pesquisa investigou a terceirização como forma de organização, o modelo de gestão como mecanismo de adequação das relações, e a atuação em equipes como elemento estruturante do trabalho. Buscou-se entender como se dá o atendimento dos interesses e necessidades humanas e empresariais, com foco na formação da identidade psicológica e inserção social dos indivíduos, na eficiência operacional e competitividade das empresas.   Palavras-Chave: Terceirização, relações de trabalho, equipes de trabalho.     ABSTRACT The restructuring of production, since the 70’s has been established a new order demanding for workers capacities and dedication, aiming to obtain more quality and productivity in the means of production. In this new dynamic have developed the outsourcing, in which enterprises hire a specialized company to execute the activities which are not part of the critical processes, the core business; with an aim of cost reduction and increase of the efficiency rate. The manner to produce goods or services is a result of the conjugation of material resources, technology and labour force, which allows a wide

    Full Text Available No intuito de compreender os modos de enfrentamento de um fazer diário que envolve o convívio profissional com a morte violenta é que realizei uma pesquisa de cunho etnográfico, de 2007 a 2010, no Departamento de Criminalística (DC do Instituto-Geral de Perícias (IGP do Rio Grande do Sul. Entrevistas, observação simples e participante correspondem às técnicas escolhidas para a obtenção dos dados, e a análise dos achados de campo seguiu os ditames dos estudos etnográficos ao atentar para as interlocuções entre a visão êmica, a visão ética e os teóricos referenciados. A sustentação teórica sobre a morte encontra respaldo nos estudos de DaMatta (1987, Ariès (2000, Elias (2001 e Bauman (2008. Elias (2001 afirma que a morte na contemporaneidade foi recalcada sob dois âmbitos: o individual e o social. O recalque individual impõe uma distância dos moribundos, enquanto o recalque social se dá com a morte ocupando os bastidores da vida social. No caso dos servidores do DC, o enfrentamento da consciência da morte e da violência se dá pela ênfase no “outro mundo”, das almas; pela desconstrução, ao descobrir as causas da morte violenta por meio da busca pela verdade, mediante a utilização do método e das técnicas científicas; pela banalização, em que o corpo da vítima é visto como um “objeto” ou um “boneco”; por meio do riso, do humor negro; o enfrentamento de uma morte violenta no âmbito pessoal mediante o exercício profissional que desafie o indivíduo a ficar frente a frente com essa realidade. Os trabalhos de Marta et al. (2009, Combinato e Queiroz (2006 e Brêtas, Oliveira e Yamaguti (2006 mostram que os sujeitos por eles pesquisados não foram treinados para lidar com a morte no âmbito do trabalho, situação idêntica foi detectada junto aos servidores do DC, sendo a proposição educacional de Kovács (2005 aplicável ao caso em questão.
