Abnormal platelet aggregation was found in eight (44%) of 18 patients with beta-thalassaemia major and transfusional iron overload. The aggregation defect bore no correlation with the degree of hepatic fibrosis, liver function tests, whether or not splenectomy had been performed, the degree of iron overload, haematocrit, platelet count, serum vitamin E level, or leucocyte ascorbate concentratio...

Chiclana et al. [Chiclana, F., Herrera-Viedma, E., Herrera, F., Alonso, S. (2007). European Journal of Operational Research 182, 383–399] provided some IOWA operators for aggregating the individual fuzzy preference elations. The aim of this work is further to study their desired properties under group decision making problem with fuzzy preference relations. First, it is proved that the collecti...

OBJECTIVE While familial aggregation of bulimia nervosa (BN) is known to occur, the extent to which aggregation of a broader spectrum of eating disorders (ED) occurs in the families of individuals with BN is less certain. METHOD Direct interviews and blind best-estimate diagnostic procedures were used to assess lifetime histories of EDs among first-degree relatives (n = 177) of probands with ...

The quality of manufactured products is characterized by many controllable quality factors. These factors should be optimized to reach high quality products. In this paper we try to find the controllable factors levels with minimum deviation from the target and with a least variation. To solve the problem a simple aggregation function is used to aggregate the multiple responses functions then a...

OBJECTIVE To asses the degree of erythrocyte aggregation in the peripheral blood of women with preterm premature rupture of the membranes (PPROM). STUDY DESIGN This was a prospective case control study. Twenty patients with preterm premature rupture of the membranes and matched controls were recruited at the Lis Maternity Hospital. A slide test and image analysis were used to quantitate the d...

OBJECTIVE Our aim was to evaluate familial aggregation of migraine in a large group of Portuguese families, and to assess if familial aggregation differs between MA and MO. METHODS Familial aggregation was evaluated by estimating relative risk (RR) of migraine in 143 first-degree relatives of 50 probands with MA, in 196 first-degree relatives of 94 probands with MO and also in proband's spous...

the ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. in the present work, aggregation of the purified hemoglobinin adult (hba) and in fetus or newborn (hbf) in the presence of nitrite ions were studied.hemoglobin aggregation was perform...

aggregation of pharmaceutical proteins reduces the efficiency and increases the cost of production. it can also lead to the reduced efficacy of drug or cause side effects on the patient’s body. investigating how to create them plays an important role to find agents that prevents the aggregation. this study was allocated for understanding the mechanism of formation of the reteplase protein using...

Data aggregation in wireless sensor networks is widely accepted as an essential paradigm for energy efficient routing but with low reliability under node and link failures. In wireless sensor networks, malicious sensor nodes send false data reports to distort aggregation results. Existing trust systems rely on general reputation to mitigate the effect of this attack. This paper presents one of ...

in this work, we define a fuzzy soft set theory and its related properties. we then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.
