Among livestock types, beef cattle production is ranked as a very important sub-sector in the extremely harsh natural conditions characterising the northern uplands of Vietnam, where ethnic minorities are often concentrated on land resources which are not hospitable to crops. To help local people to escape from poverty, many organisations have initiated development projects featuring beef cattle production, but it still remains under-developed, hence the generally high level of poverty faced by farmers. <br /> <br />Thus, the study aims to assess the characteristics and appropriateness of beef cattle feeding systems, which are compared from the point of view of sustainability. <br /> <br />Stratified sampling was used to select 97 households within free-range, part-time grazing, and cut-and-carry feeding systems, which were surveyed in Bac Kan province between 2007 and 2009. The collection of field data was implemented using various survey instruments such as structured questionnaires and interview guides. Data processing consisted in descriptive statistics, correlations between the variables, and the calculation of socio-economic indicators. Based on the sample surveyed, the differences between the three systems of cattle management were highlighted. <br /> <br />Access to grazing land and its topography, the ethnicity of the communities, the relative importance of agricultural and forest production, and opportunities for off-farm employment were all factors influencing the cattle systems. Those using the “cut-and-carry” fodder system are practicing the most efficient husbandry style among the systems from both the social and economic points of view, except for lack of proper management and use of cattle manure. Manure use for cultivation in this system was limited because of the predominantly steep slope lands and the habits of the indigenous peoples. Animal manure utility was evaluated as less important in the cut-and-carry system compared to other systems practiced in the lowlands. <br /> <br />However, good prospects are seen to improve conditions in the rural uplands in the future. Thus, different strategies should be implemented to fill the gap and improve the position of farmers. The study derives helpful recommendations for farmers keeping beef cattle to strongly develop their production, alleviate poverty, and improve their livelihoods. [less ▲]

In this article we describe the organization of the ovine BEGAIN gene, located 138 kb proximally from the imprinted DLK1 gene and 203 kb from the CLPG mutation that causes the callipyge phenotype. We have shown that in sheep BEGAIN is ubiquitously expressed, including in skeletal muscle, throughout development. We have identified four major BEGAIN transcripts resulting from a combination of alternate promoter usage and alternative splicing. In ovine brain, kidney, liver, and skeletal muscle, these four BEGAIN transcripts exhibited paternal or biallelic expression in a tissue- and promoter-specific manner. Our results indicate that the CLPG mutation does not alter transcript levels of BEGAIN, contrary to its effect on a core cluster of genes in the DLK1-GTL2 domain. Thus, although the BEGAIN gene represents another paternally expressed gene in the ovine DLK1-GTL2 imprinted domain, its expression is not governed by the long-range regulatory element that contains the CLPG mutation.

Overbeet is de meest voorkomende congenitale tandafwijking bij het veulen. Minimale overbeten behoeven waarschijnlijk geen specifieke behandeling echter in erg aangetaste dieren kunnen zich secundaire tandproblemen ontwikkelen. Erge overbeet kan gemakkelijk bij het onvolwassen dier door middel van een orthodontische behandeling worden aangepakt. Hiertoe wordt een beugel geplaatst die de groei van de maxilla remt. Bij volwassen dieren echter zal een erge overbeet enkel middels een dure en invasieve chirurgische ingreep gecorrigeerd kunnen worden. Dit artikel geeft een overzicht van de courante terminologie ter beschrijving van overbeet bij het paard en bespreekt achtereenvolgens de verschillende mogelijkheden tot correctie van deze afwijking bij onvolwassen en volwassen dieren.

Anxiety disorders are known to be comorbid with migraine, and cortical spreading depression (CSD) is the most likely cause of the migraine aura. To search for possible correlations between susceptibility to CSD and anxiety we used the open field test in male Sprague-Dawley rats chronically treated with the preventive anti-migraine drugs valproate or riboflavin. Animals avoiding the central area of the open field chamber and those with less exploratory activity (i.e. rearing) were considered more anxious. After 4 weeks of treatment CSDs were elicited by application of 1M KCl over the occipital cortex and the number of CSDs occurring over a 2h period was compared to the previously assessed open field behavior. Higher anxiety-like behavior was significantly correlated with a higher frequency of KCl-induced CSDs. In saline-treated animals, fewer rearings were found in animals with more frequent CSDs (R=-1.00). The duration of ambulatory episodes in the open field center correlated negatively with number of CSDs in the valproate group (R=-0.83; p<0.005) and in riboflavin treated group (R=-0.69; p<0.05) as well as total time spent in the open field center in both groups (R=-0.75; p<0.05 and R=-0.58; p<0.1 respectively). These results suggest that anxiety symptoms are associated with susceptibility to CSD and might explain why it can be an aggravating factor in migraine with aura. [less ▲]

The effect of desialylation of rat and human transferrins on hepatocyte processing of the protein and its iron was studied in rats. No alteration in early transferrin catabolism was observed. Radioiron disappearance from the plasma and liver iron uptake were more rapid for asialotransferrins than for normal transferrins (P less than .001). Furthermore, radioiron plasma clearance of human tri-sialotransferrin was faster (P less than .05) and liver uptake higher (P less than .002) than for human pentasialotransferrin. When the asialoglycoprotein receptor was blocked by the prior injection of asialofetuin, asialotransferrin behaved like normal transferrin. When the transferrin receptor was blocked by the prior injection of 50 mg human diferric transferrin, iron uptake from all transferrins was delayed to such an extent that uptake through both receptors seemed to be affected. Approximately 90% of the hepatic radioiron from all transferrins was chelated by desferrioxamine and excreted into the bile, indicating its uptake by the hepatocyte rather than the reticuloendothelial (RE) cell. The rate of iron release into the plasma and its subsequent accumulation in the red cell mass over a 2-week period was similar for human asialotransferrin, ferritin, and hemoglobin iron. This study 1) confirmed that asialotransferrin-iron uptake by the hepatocyte is mediated by both transferrin and asialoglycoprotein receptors; 2) demonstrated that not only asialotransferrin but also transferrin of low sialic acid content will increase iron turnover and lead to excessive iron loading of the hepatocyte; 3) and showed that the intrahepatocyte metabolism of asialotransferrin-iron did not differ from that of iron delivered by normal transferrin.

Crossed-magnetic-field effects on bulk high-temperature superconductors have been studied both experimentally and numerically. The sample geometry investigated involves finite-size effects along both (crossed-)magnetic-field directions. The experiments were carried out on bulk melt-processed Y-Ba-Cu-O single domains that had been premagnetized with the applied field parallel to their shortest direction (i.e., the c axis) and then subjected to several cycles of the application of a transverse magnetic field parallel to the sample ab plane. The magnetic properties were measured using orthogonal pickup coils, a Hall probe placed against the sample surface, and magneto-optical imaging. We show that all principal features of the experimental data can be reproduced qualitatively using a two-dimensional finite-element numerical model based on an E-J power law and in which the current density flows perpendicularly to the plane within which the two components of magnetic field are varied. The results of this study suggest that the suppression of the magnetic moment under the action of a transverse field can be predicted successfully by ignoring the existence of flux-free configurations or flux-cutting effects. These investigations show that the observed decay in magnetization results from the intricate modification of current distribution within the sample cross section. The current amplitude is altered significantly only if a field-dependent critical current density Jc(B) is assumed. Our model is shown to be quite appropriate to describe the cross-flow effects in bulk superconductors. It is also shown that this model does not predict any saturation of the magnetic induction, even after a large number (~ 100) of transverse field cycles. These features are shown to be consistent with the experimental data. (C) The American Physical Society. [less ▲]

We have experimentally investigated the crossed magnetic field effects on bulk melt-processed YBCO single domains. The samples were first permanently magnetized along their c-axis and then subjected to several cycles of a transverse magnetic field parallel to the ab planes. The magnetic properties along the c and ab directions were simultaneously measured using a couple of orthogonal pick-up coils as well as a Hall probe placed against the sample surface. The effects of both sweep amplitude and polarity were investigated. Field sweeps of alternate polarities are shown to affect the decay of the c-axis magnetization much more strongly than field sweeps of unique polarity do. However, the c-axis magnetization does not show any saturation even after a large number of field sweeps. Next, a micro-Hall probe scanning system was used to measure the distribution of magnetic induction over the top surface of the single domain subjected to the same combination of magnetic fields. The results are shown to be consistent with those determined with the sensing coils and bring out the role played by geometric effects. (C) 2003 IEEE. [less ▲]

While anchor heads are particularly useful in the case of large bars which require significant development lengths, the ACI code provides design guidance for bars #11 or smaller. This paper presents a test of a large deep beam reinforced with a single #18 headed bar. The behavior of the beam is evaluated in comparison to the behavior of a specimen with more conventional reinforcement of 6#8 headed bars, and to the behavior of a specimen with lap-spliced anchor hooks. Despite the extreme detailing of the specimen with a single #18 bar, the beam had the same strength as the specimen with 6#8 bars. The compressive stress in front of the anchor head reached about 1.5 times the compressive strength of the concrete and the stress in the #18 bar reached about 414 MPa (60 ksi) before the beam failed in shear along a diagonal crack away from the anchorage zone. Shear strength calculations according to Appendix A of the ACI code showed that the current strut-and-tie provisions can overestimate the shear strength of deep beams by as much as 23%. [less ▲]

Non-slender reinforced concrete beams find extensive application in cases where heavy loads need to be transferred over a given span. The safety of this kind of structural elements is often critical for the safety of the structure as a whole. The research described in this thesis is devoted to studying the behaviour of lightly-reinforced non-slender beams under monotonic and reversed cyclic loads, as particular consideration is given to the load-bearing mechanisms which occur in moderately-deep beams. The choice of this topic was motivated in part by verification studies which show that the current code procedures for shear design of members without web reinforcement are least accurate in the range of transition from deep to slender beams. Furthermore, the issue of cyclic response of lightly-reinforced deep beams is of great importance for seismic assessment of existing structures, especially if the similarity between the load-bearing mechanisms in deep beams and those in other non-slender components such as coupling beams, squat shear walls, and frame joints is recognized. An experimental program consisting of ten tests of large non-slender reinforced concrete beams has been performed. All specimens failed in shear after transition from beam load-bearing mechanism to arch action (specimens without stirrups) or truss actions (specimens with stirrups). A suggested kinematic model was successfully used for interpretation of the various deformation measurements. The results showed that part of the ultimate shear was carried in the cracked concrete. It was concluded that load reversals had little effect on the overall response. A test of deep beam provided with single bar #18 demonstrated that anchorage by anchor heads is effective even when the biggest ASTM reinforcing bar is used. Comparison between experimentally-obtained and calculated shear strengths showed that the CSA code rendered reasonably conservative predictions compared to the mostly unconservative results of the ACI and EC2 codes. Theoretical work resulted in a derivation of an improved strut-and-tie model (ISTM) which is based on the CSA shear provisions but accounts for shear carried under the critical diagonal cracks of non-slender beams without web reinforcement. Verification against a large number of tests showed that the new model is consistent with physical observations and explains the transition from deep to slender beams. Furthermore, it was shown that the ISTM can be used in combination with the above-mentioned kinematic model for estimation of the ultimate displacement and deformed shape of non-slender beams.
