Digital transient torque measurement for rotating or linear AC machines (real time measurement)

The digital transient torque measuring device presented in this paper is able to make a "real time" calculation in steady-state and transient conditions of the electromagnetic torque or force of an extremely wide range of ac electrical machines supplied with sinusoidal voltages or through frequency converters with frequencies up to 30 kHz. The device needs no shaft position or speed sensors, it uses exclusively the acquisition of the stator currents and voltages. The main fields of applications are: test shop, control, measurement, integration in a control or regulation unit, element of a monitoring system

Clinical features, antimicrobial susceptibility patterns and genomics of bacteria causing neonatal sepsis in a children's hospital in Vietnam: protocol for a prospective observational study.

INTRODUCTION: The clinical syndrome of neonatal sepsis, comprising signs of infection, septic shock and organ dysfunction in infants ≤4 weeks of age, is a frequent sequel to bloodstream infection and mandates urgent antimicrobial therapy. Bacterial characterisation and antimicrobial susceptibility testing is vital for ensuring appropriate therapy, as high rates of antimicrobial resistance (AMR), especially in low-income and middle-income countries, may adversely affect outcome. Ho Chi Minh City (HCMC) in Vietnam is a rapidly expanding city in Southeast Asia with a current population of almost 8 million. There are limited contemporary data on the causes of neonatal sepsis in Vietnam, and we hypothesise that the emergence of multidrug resistant bacteria is an increasing problem for the appropriate management of sepsis cases. In this study, we aim to investigate the major causes of neonatal sepsis and assess disease outcomes by clinical features, antimicrobial susceptibility profiles and genome composition. METHOD AND ANALYSIS: We will conduct a prospective observational study to characterise the clinical and microbiological features of neonatal sepsis in a major children's hospital in HCMC. All bacteria isolated from blood subjected to whole genome sequencing. We will compare clinical variables and outcomes between different bacterial species, genome composition and AMR gene content. AMR gene content will be assessed and stratified by species, years and contributing hospital departments. Genome sequences will be analysed to investigate phylogenetic relationships. ETHICS AND DISSEMINATION: The study will be conducted in accordance with the principles of the Declaration of Helsinki and the International Council on Harmonization Guidelines for Good Clinical Practice. Ethics approval has been provided by the Oxford Tropical Research Ethics Committee 35-16 and Vietnam Children's Hospital 1 Ethics Committee 73/GCN/BVND1. The findings will be disseminated at international conferences and peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN69124914; Pre-results

Quality assessment of marketed eggs in Hanoi (Vietnam)

Poultry farming is the first sector of livestock that has been industrialized. The poultry sector plays an important role in the GDP of Vietnam. It is the second largest livestock after the pig livestock. The production and consumption of eggs in Vietnam is estimated as 5.64 billion and 102.6 eggs per person per year respectively. The aim of this study was to assess the quality of eggs in relation to the chicken breed and different marketing channels in Hanoi, Vietnam. In total, 431 chicken eggs were purchased from four different marketing channels in Hanoi, including households (89 eggs), supermarkets (152 eggs), public markets (130 eggs) and small grocery stores (50 eggs). Out of the 431 above-mentioned eggs, 119 eggs came from the commercial chicken breeds and 312 eggs from traditional local breeds. The quality of eggs for a consumer is represented by its cleanliness, nutritional quality, freshness, and price. A series of measurements is carried out just after their purchase. According to the breed and the marketing channel, highly significant differences (P 0.05) the freshness of the eggs, however, they have a significant effect (P <0.05) on the size of the eggs marketed in Hanoi. The results of this study show an important diversity in marketing channels and marketed eggs in Hanoi
