The main aim of this paper is to study fuzzy congruences of typeB semigroups. After obtaining some properties and characterizations of fuzzy good congruences on adequate semigroups, we consider fuzzy good congruences on type-B semigroups. Finally, we prove a theorem giving equivalent conditions on fuzzy cancellative congruences of such semigroups. Mathematics Subject Classification: 06F05; 20M10

Personality and heart rate variability (HRV) each are strong predictors of well-being, particularly cardiac health and longevity. The present study compares the changes in HRV during resting state in the Type ̳A‘ and Type ̳B‘ personalities. The personality of subjects is chosen according to Glazer questionnaire. In each of these two groups 30 males were taken. After general interview of these s...

The class of nearly balanced incomplete block designs with concurrence range l, or NBBD(l), is defined. This extends previous notions of “most balanced” designs to cover settings where off-diagonal entries of the concurrence matrix must differ by a positive integer l ≥ 2. Sufficient conditions are found for optimality of NBBD(2)’s under type-1 criteria, then used to establish Aand D-optimality ...

BACKGROUND Certain personalities are ascribed to physicians. This research aims to measure the extent to which physicians identify with three predetermined personalities (workaholic, Type A and control freak) and to explore links to perceptions of professional performance, and wellness outcomes. METHODS This is a cross-sectional study using a mail-out questionnaire sent to all practicing phys...

The aand l-glucosidase activity in natural samples can be readily measured during short incubation times (20 min) by using the artificial substrates 4-methylumbelliferyl-a-D-glucoside and 4-methylumbelliferyli--Dglucoside. The apparent Km of both aand ,I-glucosidase for these respective substrates is 0.01 ,uM. The homologous disaccharides maltose and cellobiose competitively inhibit aand I-gluc...
