Abstract Co-simulation is a method which makes it possible to study the electric machine and its drive at once, as one system. By taking into account the actual inverter voltage waveforms in a finite element model instead of using only the fundamental, we are able to study the electrical machine's behavior in more realistic scenario. The recent increase in the use of variable speed drives justifies the research on such simulation techniques. In this paper we present the co-simulation of an inverter fed permanent magnet synchronous machine. The modelling method employs an analytical variable speed drive model and a finite element electrical machine model. By linking the analytical variable speed drive model together with a finite element model the complex simulation model enables the investigation of the electrical machine during actual operation. The methods are coupled via the results. This means that output of the finite element model serves as an input to the analytical model, and the output of the analytical model provides the input of the finite element model for a different simulation, thus enabling the finite element simulation of an inverter fed machine. The resulting speed and torque characteristics from the analytical model and the finite element model show a good agreement. The experiences with the co-simulation technique encourage further research and effort to improve the method.

Background: Laparoscopic living-donor nephrectomy is the current epitome of living kidney donation surgery. We review our experience in living-donor nephrectomies over the last 19 years, transitioning from open surgery to hand-assisted laparoscopy to full laparoscopic techniques. Methods: We retrospectively identified all living-donor nephrectomies performed at our institution from 1976 to 2018. The donors were categorised according to surgical techniques: open (ODN), hand-assisted laparoscopy (HALDN) and full laparoscopy (LDN). We reviewed changes in donor demographics over the years. Surgical outcomes between groups were compared from 2000 to 2018. We also compared the outcomes of LDN between different time periods to evaluate our learning curve. Results: A total of 214 living-donor nephrectomies were performed between 2000 and 2018. The majority were left sided (93%) and had single renal artery anatomy (90%). There were 22 ODN, 20 HALDN and 163 LDN cases. The mean operating time was 84±43, 151±32 and 179±37 minutes for ODN, HALDN and LDN, respectively ( p<0.001). There were no statistically significant differences in mean warm ischaemia times ( p=0.921) and length of hospital stay ( p=0.114) between groups. The overall 30-day surgical morbidity rate was 9.3%, with a major complications rate of 0.9%. The mean warm ischaemia time for LDN was significantly different ( p<0.001) between time periods: 281±260, 184±94 and 140±42 seconds for the periods between 2005–2009, 2010–2014 and 2015–2018, respectively. Conclusion: This study confirms the safety of living-donor nephrectomies performed at our institution, a centre with a modest volume of kidney transplants.

Anthropological insights into the use of race/ethnicity to explore genetic contributions to disparities in health were developed using in-depth qualitative interviews with editorial staff from nineteen genetics journals, focusing on the methodological and conceptual mechanisms required to make race/ethnicity a genetic variable. As such, these analyses explore how and why race/ethnicity comes to be used in the context of genetic research, set against the background of continuing critiques from anthropology and related human sciences that focus on the social construction, structural correlates and limited genetic validity of racial/ethnic categories. The analyses demonstrate how these critiques have failed to engage geneticists, and how geneticists use a range of essentially cultural devices to protect and separate their use of race/ethnicity as a genetic construct from its use as a societal and social science resource. Given its multidisciplinary, biosocial nature and the cultural gaze of its ethnographic methodologies, anthropology is well placed to explore the cultural separation of science and society, and of natural and social science disciplines. Anthropological insights into the use of race/ethnicity to explore disparities in health suggest that moving beyond genetic explanations of innate difference might benefit from a more even-handed critique of how both the natural and social sciences tend to essentialize selective elements of race/ethnicity. Drawing on the example of HIV/AIDS, this paper demonstrates how public health has been undermined by the use of race/ethnicity as an analytical variable, both as a cipher for innate genetic differences in susceptibility and response to treatment, and in its use to identify ‘core groups’ at greater risk of becoming infected and infecting others. Clearly, a tendency for biological reductionism can place many biomedical issues beyond the scope of public health interventions, while socio-cultural essentialization has tended to stigmatize ‘unhealthy behaviours’ and the communities where these are more prevalent.
