Effect of Level of Barley in Finishing Diets of Swine Performance and Carcass Characteristics

Barley continues to be a feed ingredient available to swine producers in South Dakota, that can be used as a substitute for corn. In experiments reported in the 1984 South Dakota Swine Day Proceedings we reported that pigs fed barley diets gained slower during the grower period (60 to 125 lbs) but not during the finisher period (125 to 220 lb). This experiment was designed to evaluate various levels of barley, 0 to 100% of the grain, in diets fed to pigs from an average of 80 to 220 lb market weight

Comparison of Required Energy Intake of Gilts and Sows to Obtain Recommended Gestation Gains

Three trials utilizing 104 crossbred sows and gilts were conducted to evaluate energy needs to provide_ predetermined gestation gains for gilts and sows. In trial l» gilts required similar energy levels (6918 kcal ME) to gain .9 lb/day as bred sows required (7008 kcal ME) to gain .5 lb/day during gestation. Open sows and gilts consumed much more energy but were unable to gain at the predetermined levels. In trial 2, 8 month old gilts required more energy than mature sows (5898 vs 5028 kcal ME) and 11 month old gilts consumed more than either other group to gain at an intermediate level. In trial 3, a daily difference in energy consumption of approximately 800 kcal of ME existed between gilts and sows fed to predetermined gestation gains. If the results of the last two trials are averaged, a difference in energy consumption of 840 kcal of ME/day is found between gilts fed to gain .9 lb/day and sows fed to gain .5 lb/day. This difference is approximately .6 lb of additional gestation feed needed per day for the bred gilt if gestation gain is used as a criteria of evaluation

Comparison of Sow and Gilt Performance as Affected by Gestation Energy Intake

Gestation energy needs of sows include maintenance as well as tissue growth associated with pregnancy and fetal development. Gilts have the additional demands of body tissue growth but less maintenance needs because of smaller body size. Differences in total daily energy needs between sows and gilts have not been resolved. Results of three trials conducted to compare energy needs for specific gestation gains for sows and gilts were reported last year (Swine 84-10). These results suggested the need for approximately 870 Kcal of additional metabolizable energy (ME) (.6 lb of feed) for gilts with the desired gains of .5 lb/day for sows and .9 lb/day for gilts. The trial reported herein was designed to evaluate comparative performance of sows and gilts fed a wide range of ME levels

Influence of Gestation Energy on Large White x Landrace Sow Productivity

Production remains extremely important in our swine industry today. In the past 5-10 years, there has been an increase in the usage of white breeds in swine herds. The white or mother breeds are noted for their increased productivity; however, a question has stirred as to the feeding regime of these productive females. This question is important as feed costs are the major portion of operating expenses for the hog producers. Little controlled research has been conducted in the United States to establish the caloric intake requirement of the white sows during gestation. The National Research Council (NRC, 1979) lists the energy requirement of the bred sow and gilt as 6.1 Meal of. digestible energy (DE) or 5.8 Meal of metabolizable energy (ME) daily. This recommendation is largely based on research with traditional 3-way crossbred sows. Great Britain swine researchers in the 1960\u27s and United States researchers Frobish and workers (1966) were the last to evaluate the effect of gestation energy on strictly white sows. To help answer the current concerns of white sow nutrition, this research project was designed to study the influence of gestation energy on Large White x Landrace sow productivity

Effect of P‐induced gettering on extended defects in n‐type multicrystalline silicon

AbstractThe electrical properties and the minority charge carrier recombination behaviour of grain boundaries (GBs) and intragrain dislocations in different n‐type multicrystalline silicon (mc‐Si) ingots were systematically studied through microwave‐detected PhotoConductance Decay (µW‐PCD), Electron Beam Induced Current (EBIC) and PhotoLuminescence (PL) spectroscopy on as‐grown samples and on samples submitted to P‐diffusion step. It was confirmed that the overall quality of n‐type mc‐Si is high, indicating that n‐type‐Si is a valid source for photovoltaic applications. As expected, the average lifetime increases after the P‐diffusion process, which induces impurity gettering effects at the external surfaces, like in the case of p‐type samples, but an evident local increase of electrical activity of some GBs after that process was also observed using the EBIC mapping technique. Apparently, a redistribution of impurities occurs at the processing temperature and impurities are captured at the deepest sinks. In fact, while all GBs act as heterogeneous segregation/precipitation sites, some of them will compete with the external surfaces sinks, partly vanishing the effect of P‐gettering. Last but not least, it was experimentally demonstrated that the average lifetime values measured with the µW‐PCD technique well correlate with the recombination activity of GBs measured with the EBIC technique, showing the extreme importance of GBs on the effective lifetime of this material.

Effectiveness of Mechanisms and Models of Coordination between Organizations, Agencies and Bodies Providing or Financing Health Services in Humanitarian Crises: A Systematic Review.

BACKGROUND: Effective coordination between organizations, agencies and bodies providing or financing health services in humanitarian crises is required to ensure efficiency of services, avoid duplication, and improve equity. The objective of this review was to assess how, during and after humanitarian crises, different mechanisms and models of coordination between organizations, agencies and bodies providing or financing health services compare in terms of access to health services and health outcomes. METHODS: We registered a protocol for this review in PROSPERO International prospective register of systematic reviews under number PROSPERO2014:CRD42014009267. Eligible studies included randomized and nonrandomized designs, process evaluations and qualitative methods. We electronically searched Medline, PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, PsycINFO, and the WHO Global Health Library and websites of relevant organizations. We followed standard systematic review methodology for the selection, data abstraction, and risk of bias assessment. We assessed the quality of evidence using the GRADE approach. RESULTS: Of 14,309 identified citations from databases and organizations' websites, we identified four eligible studies. Two studies used mixed-methods, one used quantitative methods, and one used qualitative methods. The available evidence suggests that information coordination between bodies providing health services in humanitarian crises settings may be effective in improving health systems inputs. There is additional evidence suggesting that management/directive coordination such as the cluster model may improve health system inputs in addition to access to health services. None of the included studies assessed coordination through common representation and framework coordination. The evidence was judged to be of very low quality. CONCLUSION: This systematic review provides evidence of possible effectiveness of information coordination and management/directive coordination between organizations, agencies and bodies providing or financing health services in humanitarian crises. Our findings can inform the research agenda and highlight the need for improving conduct and reporting of research in this field

LARGE AREA SCREEN PRINTED N-TYPE MC-SI SOLAR CELLS WITH B-EMITTER: EFFICIENCIES CLOSE TO 15% AND INNOVATIVE MODULE INTERCONNECTION

ABSTRACT In this paper we present n-type Si solar cells on large area mc-Si wafers with a boron diffused emitter at the front side. The focus of our studies is mainly related to the front surface of the solar cell. We have optimised BBr3-diffusion and in-situ oxidation with respect to the homogeneity of the sheet resistance and substrate degradation. After diffusion even a slight improvement of the minority charge carrier lifetime was measured, which can be related to Bgettering. The emitter is contacted by AgAl-paste and passivated by thermal SiO2. The development and optimisation of all processes led to solar cells with efficiencies of 14.7% on mc-Si and 17.1% on Cz-Si substrates. In addition to this we present an innovative interconnection of modules using our developed cell (patent pending). We show an alternate serial interconnection of p-and n-type solar cells resulting in easier module processing

The sociological significance of domestic violence: Tensions, paradoxes and implications

Sociology and sociological theory has been effective in analyzing societal and institutional conflict and violence, but less so the specifics of interpersonal violence. This article examines the sociological significance of domestic violence. This relationship, or sometimes its neglect, is underlain by several tensions and paradoxes, which in turn have broader implications for sociology and sociological theory. These matters are examined through: the possible paradox of violence and intimacy in the phenomenon of domestic violence; the importance of the naming and framing of such violence; explanation, responsibility and agency; and gender, hegemony and discourse in men’s violence to known women, as part of a multifaceted power approach
