performances of electronic and mechanical draft control systems on a mf399 tractor were the objectives of the study to be evaluated and compared under field conditions. hence, the effects of two draft control systems (mechanical and electronic) under four ground speed levels and three set values of draft levels on rear wheel slippage, fuel consumption, compressive force within the top link and ...

A cluster of papers in this month’s Bulletin describes the facets of maternal and congenital syphilis and lists the current barriers to effective control and treatment. Bidia Deperthes et al. (pp. 410–416) describe antenatal syphilis control programmes in Bolivia, Kenya and South Africa, and outline ways to improve the effectiveness of these programmes. Sarah Hawkes et al. (pp. 417–423) take a ...

Introduction:  Nowadays  the  medical,  therapeutic  and  pharmacological  application  of  magnetic  fields  (MF)  and  its  biological  effect  has  raised  question  about  the  safety  of  MF.  This  study  aimed  at  scrutinizing the effect of static MF on the resistance of S. aureus to antibiotic.  Materials and Methods: This prospective, case–control study was conducted to evaluate the e...

A high intake of fruit and vegetables (FV) has been shown to be associated with reduced risk of a number of chronic diseases, including CVD. This review aims to provide an overview of the evidence that increased FV intake reduces risk of CVD, focusing on studies examining total FV intake. This evidence so far available is largely based on prospective cohort studies, with meta-analyses demonstra...

Systemic lupus erythematosus (SLE) is a multi-system inflammatory disease where genetic susceptibility coupled with largely undefined environmental factors is reported to underlie the aetiology of the disease. One such factor is low vitamin D status. The primary source of vitamin D is endogenous synthesis following exposure of the skin to UVB light. Photosensitivity, sunlight avoidance and the ...
