Given a set N of radio stations located on an Euclidean space, a source station s and an integer h (16 h6 |N | − 1), the minimum bounded-hop broadcast range assignment problem consists in 8nding a range assignment for N of minimum total power consumption that allows broadcast operations from s to every station in N in at most h hops. The problem is known to be NP-hard on d-dimensional spaces fo...

INTRODUCTION Diarrhoea is one of the main causes of morbidity and mortality among children in sub-Saharan Africa, and one of the main causes of hospital admissions in rural areas of Kenya. In Kenya, antimicrobial resistance surveillance has been conducted only at the institutional levels, with limited sharing of information and analysis of data. As a result, the actual scale of regional or nati...

INTRODUCTION Hemorrhage is a major complication after percutaneous nephrolithotomy (PCNL). In the current study, we analyzed the risk factors for severe bleeding after PCNL. MATERIAL AND METHODS Medical records of 982 consecutive patients undergoing PCNL at the Department of Urology, the Third Xiangya Hospital, were reviewed. The type of stone included: solitary (n = 471), multiple (n = 192) ...

A series of experiments was undertaken to determine whether kosher salt reduces persistence of Salmonella serotypes that might cross-contaminate chicken skin on the conveyor belt between the soaking and salting stations in a kosher processing line. The line was simulated in the laboratory because Salmonella could not be inoculated onto chickens in a commercial plant. Prevalence of Salmonella Ty...

OBJECTIVES This study examines whether aspects of social relations at baseline are related to functional decline at 5-year follow-up among nondisabled old men and women. METHODS The investigation is based on baseline and follow-up data on 651 nondisabled 75-year-old persons in Jyväskylä (Finland) and Glostrup (Denmark). The analyses are performed separately for men and women. Possible selecti...

This study aims to improve the understanding of consumer behaviour in use a disruptive technology such as online supermarkets. By this process, we can gain further insight into behaviour. Based on sample 651 supermarket users, structural equations are used empirically analyse validity model. The effect flow is identified terms perceived ease use, usefulness and current importance factor demonst...
