In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...

BACKGROUND Early identification of children <5 yrs with acute malnutrition is a priority. Acute malnutrition is defined by the World Health Organization as a mid-upper-arm circumference (MUAC) <12.5 cm or a weight-for-height Z-score (WHZ) <-2. MUAC is a simple and low-cost indicator to screen for acute malnutrition in communities, but MUAC cut-offs currently recommended by WHO do not identify t...

OBJECTIVES To describe (1) the prevalence of overweight and obesity and their association with physical activity; (2) the effect of different cut-off points for body mass index (BMI) on weight status categorisation; and (3) associations of weight status with perceptions of body size, health and diet quality. DESIGN A cross-sectional study. SETTING Secondary schools in Barbados. SUBJECTS A...

The cross-sectional hospital based study was undertaken to provide an efficient and useful cut off point of maternal early third trimester weight, for low birth weight (LBW), based on receiver operating characteristics (ROC) curve among Bengalee mothers of Kolkata, India. A total of 233 mother-baby pairs were included in the present analysis. The means for maternal age and weight were 23.44 (SD...

We tried to understand whether there are significant cut off values simply determining body mass index (BMI). The study was performed in Internal Medicine Polyclinics on consecutive check up patients aged between 15 and 70 years to see possible consequences of excess weight on health and to avoid debility induced weight loss in elders. Insulin using diabetics and patients with devastating illne...

The paper analyses Vesna Parun’s humorous literature - satirical poetry and short forms such as aphorisms epigrams from the perspective of recent theoretical elaborations humour comic. interpretation is based on presumption that author’s poetic a kind political event can put pressure power systems in various areas human life. It encourages readers to question supposedly unquestionable worldview...

It is rigorously shown that the fluctuation formula, which is used in simulations to calculate the dielectric constant of interaction site models, corresponds to the reaction field with an individual site cut-off rather than with the usual molecular center of mass truncation. Within the molecular cut-off scheme, a modified reaction field is proposed. An influence of the truncation effects is di...
