Single Support Phase

Greyhounds are the fastest breed of dog and can reach a speed up to 68 km/h. These racing animals sustain unique injuries seldom seen in other breeds of dog. The highest rate of life-threatening injuries in these dogs is hock fracture, mostly of the right hind-leg. One of the main injury contributing factors in this sport is the track surface. There are some studies into the ideal track surface composition for greyhound racing but almost no study has investigated the body–surface interaction. Accordingly, the purpose of this work is to study the effect of surface compliance on the galloping dynamics of greyhounds during the hind-leg single-support phase which is a critical phase in hock injuries. Thus, a three degrees-of-freedom model for the greyhound body and substrate surface is designed using spring-loaded inverted pendulum method. The results showed that forces acting on the hind-leg were substantially affected when the surface compliance altered from the relatively hard (natural grass) to a relatively soft surface (synthetic rubber). The main contribution of this work is designing a mathematical model to predict the dynamics of the hock and the hind-leg as the most vulnerable body parts in greyhounds. Furthermore, this model can be used to optimise the greyhound track surface composition and therefore improve the safety and welfare within the greyhound racing industry.

No one wants to be treated like an object, regarded as an item of property, or put up for sale. Yet many people frame personal autonomy in terms of self-ownership, representing themselves as property owners with the right to do as they wish with their bodies. Others do not use the language of property, but are similarly insistent on the rights of free individuals to decide for themselves whether to engage in commercial transactions for sex, reproduction, or organ sales. Drawing on analyses of rape, surrogacy, and markets in human organs, this book challenges notions of freedom based on ownership of our bodies and argues against the normalization of markets in bodily services and parts. The book explores the risks associated with metaphors of property and the reasons why the commodification of the body remains problematic. The book asks what is wrong with thinking of oneself as the owner of one's body? What is wrong with making our bodies available for rent or sale? What, if anything, is the difference between markets in sex, reproduction, or human body parts, and the other markets we commonly applaud? The book contends that body markets occupy the outer edges of a continuum that is, in some way, a feature of all labor markets. But it also emphasizes that we all have bodies, and considers the implications of this otherwise banal fact for equality. Bodies remind us of shared vulnerability, alerting us to the common experience of living as embodied beings in the same world. Examining the complex issue of body exceptionalism, the book demonstrates that treating the body as property makes human equality harder to comprehend.

ABSTRACT Necrotizing fasciitis is a life threatening condition that can be quickly spread through the flesh surrounding the muscle. The disease can be polymicrobial, or caused by group A beta hemolytic Streptococci, or by Clostridium spp. We present a case of a 7 years old girl, which was hospitalized in Children Infectious Diseases Department in a 7th day of chickenpox (hematic crusts all over the body), high fever, asthenia, vomiting, oligoanuria, and tumefaction, pain and functio lessa in the right thigh. In a very short time in the right thigh swelling, edema and congestion have increased gradually, and in the third highest middle thigh the ecchymotic areas appeared evolving towards bubbles and blisters which included the right thigh and calf. After excluding the diagnosis of thrombophlebitis was raised suspicion of necrotizing fasciitis. CT pelvic scan evidenced pelvic asymmetry by maximus and medium right gluteal muscles swelling with important inflammatory infiltrate extended laterally in the subcutaneous adipose tissue. In blood culture was isolated Eggerthella lenta, and from throat swab was isolated group A Streptococci. Treatment consists of a combination of antibiotics associated with intravenous immunoglobulin administration. Despite medical treatment evolution worsened and required transfer in a pediatric surgery department where emergent surgical debridement associated with intensive antibiotic therapy was done. After this intervention evolution was slowly favorable without major limb dysfunction. Polymicrobial necrotizing fasciitis is a severe disease, which if recognized early can have a favorable outcome.

The body of a hermit crab shows asymmetrical morphology, which may be related to utilization of the dextral shell. To examine the effect of the shell, we reared Pagurus filholi (De Man, 1887) from the glaucothoe stage to full-sized adults, in a sinistral shell, in a straight tusk shell, without a shell, and in a normal dextral shell as a control. Body parts that show the most conspicuous asymmetry, uropods, pleopods and chelipeds, were checked at the time of the shedding of exuviae during rearing. No inversion of laterality on these characters was observed. However, in crabs subjected to conditions other than a dextral shell, the otherwise rather short right uropod became somewhat extended, and in those reared in sinistral shells, the right major cheliped was more enlarged.

Long duration automobile-induced vibration is the cause of many ailments to humans. Predicting and mitigating these vibrations through seat requires a good model of seated human body. A good model is the one that strikes the right balance between modelling difficulty and simulation results accuracy. Increasing the number of body parts which have been separately modelled and increasing the number of ways these parts are connected to each other increase the number of degrees of freedom of the entire model. A number of such models have been reported in the literature. These range from simple lumped parameter models with limited accuracy to advanced models with high computational cost. However, a systematic comparison of these models has not been reported till date. This work creates eight such models ranging from 8 to 26 degrees of freedom and tries to identify the model which strikes the right balance between modelling complexity and results accuracy. A comparison of the models’ prediction with experimental data published in the literature allows the identification of a 12 degree of freedom backrest supported model as optimum for modelling complexity and prediction accuracy.

The study was designed to determine the size of some body parts of the Super Kampong chicken and its relationship with body weight. The study was conducted at the Teaching Farm of Animal Science Faculty, University of Mataram, in Lingsar Village, West Lombok. The study used 60 male and 96 female Super Kampong chickens which were maintained intensively. The variables observed were body weight, head circumference, neck length, wing length, back length, chest circumference, chest width, upper and lower thigh length, metatarsus length, metatarsus circumference, and third finger length. Measurements were made for each individual bird at 13 weeks of age using yarn then measured with a tape measure, while the dimension of chest width was assigned  by measuring the distance between the right and right sides of the chest using calipers. The results found that the body parts that had the biggest contribution to the body weight of the Super Kampong chickens at 13 weeks old were the size of the lower thigh length in the male chicken and the size of the chest circumference in the female chicken.

OBJECTIVES: For violinists, it is common practice to play while standing or sitting. When playing in an orchestra, generally two persons share one music stand, with one sitting to the right and the other to the left of the stand. The present study investigated specific movement patterns while playing in these different positions. METHODS: Using a posturographic device and 3D motion capture, the body weight distributions and specific body movements of 19 violinists were analyzed. RESULTS: Results showed unbalanced weight distributions while sitting in front of or oriented to the right of the music stand compared to the almost even distributions while standing or oriented to the left of the stand. Analyses of movement patterns showed significant differences between standing and sitting, mainly in the upper body parts with less movability while sitting. While sitting in front of or oriented to the right of the music stand, the right bowing arm showed more restricted movements compared to other positions. CONCLUSION: The playing positions are discussed with regard to possible physiological stress and health risks. The study emphasizes the importance of different playing positions and offers starting points for discussion of postural influences and sensible handling of the instrument in performance and practice for violinists.

BackgroundDelusions relating to the body, a ready source of information about the immediate experiences of psychotic patients, have not been systematically studied. We attempted an account of the phenomena, looking for differences between diagnostic groupings in the type and lateralisation of such phenomena, and for evidence of localisation.MethodSomatic delusions elicited at interview with 550 Research Diagnostic Criteria-diagnosed psychotic patients were categorised according to content, and the results were compared across diagnostic groupings.ResultsSignificant differences were demonstrated, both at the level of individual delusions and in the nature and overall pattern of such delusions. There were also differences between diagnostic groups in the choice of body parts involved. Among male patients there were significant differences in laterality between the groups, with schizophrenic subjects locating abnormal phenomena principally on the left and depressive subjects on the right. A provisional taxonomy of bodily delusions was developed.ConclusionPhenomenological differences between the psychoses were demonstrated and the results offer some support for current hypotheses of localisation of brain dysfunction in the psychotic illnesses.

Motorcyclists are road users that highly exposed to hand-arm vibration that may contribute to body discomfort and fatigue that eventually will lead to road accidents and injuries. The two main objectives of this study are to identify the body parts that experience discomfort among motorcyclist and to understand the vibration exposure effect on different road types. In this study, two research methodologies were used; first, a survey questionnaire of 100 motorcyclists and second, an experimental study on hand-arm vibration (HAV) measurement exposed on motorcyclist using accelerometer mounted on the right side handlebars of the motorcycle. Two male respondents with a different weight range, 45-65 kg and >70 kg are selected for this experiment. The experiment was conducted on two different types of roads: tarmac road and pave road within a speed limit of 20-40 m/s2. Results of the study showed that the motorcyclist usually experienced body discomfort at lower back, upper back, wrist, buttock and neck area. The root-mean-square (r.m.s) frequency-weighted acceleration on the handlebars of the motorcycles was in the range of 0.07 m/s r.m.s for the tarmac road and 0.42 m/s r.m.s for the pave road. This value shows that different road type is affecting the vibration exposed to the motorcyclist. Clearly there’s a vibration felt by the motorcyclist but not on the degree of causing pain but a prolonged exposure to this vibration may induce discomfort and injuries.

Abstract Background COVID-19 (severe acute respiratory syndrome coronavirus 2) infected patients have increased risk for thrombotic events, which initially may have been under recognized. The existence of cardiovascular emboli can be directly life threatening when obstructing the blood flow to vital organs such as the brain or other parts of the body. The exact mechanism for this hypercoagulable state in COVID-19 patients yet remains to be elucidated. Case summary A 72-year-old man critically ill with COVID-19 was diagnosed with a free-floating and mural thrombus in the thoracic aorta. Subsequent distal embolization to the limbs led to ischaemia and necrosis of the right foot. Treatment with heparin and anticoagulants reduced thrombus load in the ascending and thoracic aorta. Discussion One-third of COVID-19 patients show major thrombotic events, mostly pulmonary emboli. The endothelial expression of angiotensin-converting enzyme-2 receptors makes it feasible that in patients with viraemia direct viral-toxicity to the endothelium of also the large arteries results in local thrombus formation. Up to date, prophylactic anticoagulants are recommended in all patients that are hospitalized with COVID-19 infections to prevent venous and arterial thrombotic complications.
