The influence of dipping in hot salt solution on water absorption in nylon6 composites with dispersed aluminum powders was investigated. Dipping in hot salt solution (3mass%NaCl in distilled water) for 10 s at 373K increased the overweight of composite samples, whereas the addition of aluminum with dispersed powders (A1-addition) from zero to 40 vol%Al decreased the overweigh of the sample. Bas...

One typically expects classifiers to demonstrate improved performance with increasing training set sizes or at least to obtain their best performance in case one has an infinite number of training samples at ones’s disposal. We demonstrate, however, that there are classification problems on which particular classifiers attain their optimum performance at a training set size which is finite. Whe...

Chitosan is a food preservative of natural origin that has drawn the attention of scientists working in the field of radiation processing and natural polymer products development. The effectiveness of 1% chitosan (CS) and chitosan oligosaccharides (COS) (chitosan subjected to γ irradiation, 50 or 100 kGy) dipping to preserve fresh beef slices during refrigerated storage was investigated. The mi...

Blood pressure variability (BPV) is a classical physiological phenomenon. This paper describes major epidemiological and clinical issues of BPV which may be important to understand the background of this interesting feature. In healthy subjects, BPV is a measure of hemodynamic condition and refl ects function of autonomic nervous system. BP fl uctuations result from the complex interaction betw...

A survey conducted in 5 magisterial districts involving rapid rural appraisal and a questionnaire showed participation in state-managed and funded dipping programmes by cattle owners in communal areas of the central Eastern Cape to be nearly complete, with 98% of livestock owners interviewed participating in all dipping events. Disease control was the main reason for participation, but farmers ...

Objective: Gestational diabetes mellitus (GDM) is related with cardiovascular risk factors. Non-dipping blood pressure pattern and high mean platelet volume, which is an indicator of increased platelet activation, are associated with cardiovascular morbidity and mortality. The aim of our study is to determine circadian variation of blood pressure and to study the impact of hematological indices...

OBJECTIVES The goal of this study was to evaluate the relationship between serum albumin levels and 24-hour ambulatory blood pressure monitoring (24-h ABPM) recordings in non-diabetic essential hypertensive patients. METHODS A total of 354 patients (mean [SD] age: 55.5 [14.3] years, 50% females) with essential hypertension and 24-h ABPM recordings were included. Patient 24-h nighttime and day...

In this paper we examine the effect of increased MFI competition, focusing on its implications for borrower targeting, both in the presence and the absence of double-dipping. In the absence of competition we find that the loans are more likely to go to relatively richer borrowers whenever inequality is not too large, and the technology is sufficiently convex. In the presence of competition, the...

background: diabetic patients have a higher prevalence of non-dipping pattern in blood pressure (bp) than general population. non-dipping arterial pressure pattern is associated with increased cardiovascular risk. the objective of this study was to investigate the association between the clinical and paraclinical characteristics of the diabetic patients with circadian bp variability. m aterials...
