Abstract:
BackgroundTail docking is common practice in the sheep industry to prevent soiling of the breech and flystrike. To ensure optimal healing after tail docking and reduce the risk of arthritis, perineal cancers and prolapses, it is recommended to dock tails equivalent to the length of the vulva. However, recent studies have found that some tails are docked too short (24–86 per cent).MethodsTo address this issue, this study aimed to identify key drivers behind tail docking length decisions. Two focus groups, phone (n=30) and online surveys (n=21) were conducted in regional Victoria, Australia to examine farmer knowledge of and attitudes towards appropriate lamb tail length and barriers to best practice. The focus group data were analysed qualitatively, and the surveys were analysed qualitatively and quantitatively.ResultsIn total, 57 per cent of farmers were classed as docking tails short. Short tail docking appeared to be influenced by unawareness of the recommended length and docking at a length that shearers approve of. Other potential factors included lack of knowledge of negative health consequences associated with short tails, importance placed on dag and flystrike prevention, and impracticality of measuring where to dock.ConclusionAddressing these factors in future education and intervention programmes may improve tail docking practice and sheep welfare.

Abstract:
A direct punching of inclined ultra-high strength steel sheets having low ductility was carried out to improve the quality of the sheared edge. In the direct punching of an inclined sheet, the contact between the sheet and punch became gradual because of touch from the bottom edge of the punch, and thus the sheared portion tended to bend in the latter half of punching. As the strength of the sheet increased, defects such as burr and secondary burnished surface were occurred around the sheared edge due to the low ductility. The range of direct punching for sheared edge without defects was shown for the high strength steel sheets. To prevent the occurrence of defects, a punch having inclined bottom was used. In this punch, the contact with the sheet was changed, the uniform contact with the inclined bottom was given. In the punch having the inclined bottom, the secondary burnished surface in the edge of 980 MPa grade steel sheet was prevented.

Abstract:
Abstract. As a sequence of Ugai (2010b), the present paper studies in detail the structure and dynamics of large-scale (principal) plasmoid, generated by the fast reconnection evolution in a sheared current sheet with no initial northward field component. The overall plasmoid domain is divided into the plasmoid reconnection region P and the plasmoid core region C. In the region P, the magnetized plasma with reconnected field lines are accumulated, whereas in the region C, the plasma, which was intially embedded in the current sheet and has been ejected away by the reconnection jet, is compressed and accumulated. In the presence of the sheared magnetic field in the east-west direction in the current sheet, the upper and lower parts of the reconnection region P are inversely shifted in the east-west directions. Accordingly, the plasmoid core region C with the accumulated sheared field lines is bent in the north-south direction just ahead of the plasmoid center x=XC, causing the magnetic field component in the north-south direction, whose sign is always opposite to that of the reconnected field lines. Therefore, independently of the sign of the initial sheared field, the magnetic field component Bz in the north-south direction has the definite bipolar profile around XC along the x-axis. At x=XC, the sheared field component has the peak value, and as the sheared fields accumulated in the region C become larger, the bipolar field profile becomes more distinct.

Abstract:
The occupation of sheep-shearing is classified as heavy to very-heavy physical work requiring a high level of energy expenditure while performing a repetitive task in a predominantly sustained trunk flexion posture. The task is further complicated by unpredictable animal behaviour. Shearing is considered to carry a high risk of injury particularly to the lumbar spine and epidemiological studies have demonstrated that the prevalence of low back pain (LBP) in shearers is high relative to other occupations. The emergence of a commercial shearing-aid (Warrie Back-Aid TM) that is purported to decrease loading on the spine, reduce injury rate and alleviate symptoms of spinal origin has been welcomed by many sectors of the wool-harvesting industry. However, the precise biomechanical influence of the Warrie Back-Aid TM (WBA) on the sheep-shearing task has not been quantified. The purpose of this study was to investigate the effect of the WBA on three-dimensional kinematics and electromyography of the trunk for 12 experienced shearers during the occupational task of sheep-shearing. Sheep-shearing is a highly patterned process comprised of specific interlinked phases. Nine distinct phases of the shearing-task where the harness was worn during the removal of the sheep�s fleece were investigated. The study used an opto-electronic motion analysis system and rigid body dynamic modelling. The shearer�s trunk and pelvis were considered as a series of three coupled rigid segments; pelvis, lumbar, and thorax with four passive retro-reflective markers defining each segment. The kinematic variables of angular displacement, velocity and acceleration at the thoraco-lumbar and lumbo-pelvic joint centres were calculated for each shearer while shearing with and without the WBA. An eight channel sEMG telemetry system was used to simultaneous record activity in four pairs of trunk muscles. Temporal analysis of the sEMG signal gave information on the duration and relative intensity of trunk muscle activity. The results demonstrated that the task of sheep-shearing required endurance-based muscle activity and the adoption of quasi-static posturing combined with complex asymmetrical trunk motion for extensive periods of the task time. There was considerable variability in the trunk motion of individual shearers despite the pattern-taught and repeatable nature of the shearing task. The introduction of the WBA had no effect on the time taken to shear or trunk kinematics however it resulted in reductions in muscular activity of the trunk extensors. When the complete shearing task was analysed there was a statistically significant reduction in mean intensity of muscle activity for the left multifidus (p = 0.010), right multifidus (p = 0.001), right iliocostalis (p = 0.004) and right longissimus (p = 0.002) when the WBA was used. A reduction in muscular activity of the trunk extensors during the sheep-shearing task may result in a decrease in spinal loading, energy expenditure and muscular fatigue. The clinical recommendation based on the biomechanical results of this and other studies is that the WBA should be incorporated into the practice of sheep-shearing to assist in the reduction of inherent risks associated with the shearing task. Prospective studies into the effect of the harness on LBP are required to endorse this recommendation.

Abstract:
The air found in a shearing shed environment is normally contaminated with many different airborne substances. These contaminants include dust (predominantly organic), bioaerosols (fungi and bacteria), and gases (ammonia and carbon monoxide). Respiratory disorders have been associated with exposure to the types of contaminants found in a normal sheep shearing environment. Twenty nine shearing sheds in the state of New South Wales in Eastern Australia were sampled for concentrations of airborne contaminants. Based on the results of this study the following recommendations are made for the shearing industry: under the current dust and bioaerosol exposure standards there are no requirements to investigate mechanical ventilation to reduce airborne contaminants and there is no need for respiratory protection in any of the monitored sheds. However, it is recommended that if a person has a known predisposition to respiratory illness/stress they should be closely monitored while working in a shearing shed. There are issues raised in this thesis that require further research including the need for an epidemiological study on the health of people working in shearing sheds in relation to their respiratory health. The monitoring of shearing sheds in other regions of Australia needs to be undertaken and based on available literature similar studies are also needed in other livestock industries in Australia.

Abstract:
Fine blanking is a near net shape process that is used for manufacturing of final product. In the fine blanking process, V-ring indentation is applied to create hydrostatic pressure and prevent premature fracture in an undesired direction. Furthermore, a small clearance between the punch and die is employed along with a counterforce punch that causes concentrated strain in the sheared band region. This process generally applies for sheet metal up to 6 mm. Application of this process for blanking of sheets thicker than 6 mm require some precautions for sound production. In the present research work, finite element analyses have been performed to investigate the effects of thickness variations on the shear band localization and shear surface quality in the fine blanking process. Simulations have been performed for two thicknesses of 6 and 8 mm. As blank materials, steel sheets of AISI 1045 have been used for numerical investigations.

Abstract:
The article points out on new trends in the bending technology, elimination possibilities of defects originating in bending and it deals with designing of forming line for hooks production by bending technology. It was suggested change of previous manner of production and material of produced bearing hooks as well. In previous manner of production the unfinished surface of semi product in form of roll sheet was galvanic zinc coated, it was thereafter sheared on needed length with shearing machine, followed punching in fixture, roll bending by sequence bending by help of fixture. Suggested forming line is dedicated for processing of zinc coated roll strip in automation production cycle. Forming line enables the automation work flow which includes the uncoiling of strip, feeding and leveling of strip, punching of holes and shearing of strip, roll bending of pressed part, repeated feeding of strip by leveler. Forming line consists of two-sided uncoiler without drive, feeding leveler, block of forming tools, rotary roll head. It is possible to set production of hook according to required dimensions, forming line is able to produce several dimensions of hooks with several numbers of holes. The bearing hooks from suggested original zinc coated roll strip have higher surface quality without defects. Production innovation with feeding of automation in comparison to previous manner of production enables savings of four or five workers, increasing number of produced parts per hour, to achieve repeated pressed part precision,, less manual work, increasing operation safety, minimized noise level, reducing of production costs and production of time.
