This study was carried out to evaluate the effect of different levels of garlic (Allium sativum) on growth survival and nutritional characteristics of goldfish (Carassius auratus). For this purpose, 180 goldfish with an average initial weight of 1.18± 0.08 g were introduced randomly into 12 aquaria (50×30×40 cm) at 4 groups. After one week feeding on basal diet, the treatments were fed on exper...
An important issue in survival data analysis is the identification of risk factors. Some of these factors are identifiable and explainable by presence of some covariates in the Cox proportional hazard model, while the others are unidentifiable or even immeasurable. Spatial correlation of censored survival data is one of these sources that are rarely considered in the literatures. In this paper,...
Application of data mining methods as a decision support system has a great benefit to predict survival of new patients. It also has a great potential for health researchers to investigate the relationship between risk factors and cancer survival. But due to the imbalanced nature of datasets associated with breast cancer survival, the accuracy of survival prognosis models is a challenging issue...
this study aimed to evaluate the effects of prebiotic immunoster on growth and nutrition performance, survival rate and body composition and intestine bacterial flora of common carp (cyprinus carpio) fingerlings. 15 fish with initial weight 12 + 1 g distributed in 12 tanks and fed with different dietary levels of prebiotic (0.5, 1.5, 2.5 g/kg diet) for 60 days. at the end of experimental period...
recently, reports have shown that gastric cancer has high abundance in iran and is at the second level in men, and fourth in total. this study aimed to determine the 5-year survival of gastric cancer patients and to investigate factors affecting the performance, based on tnm-7 staging system. in this study, we investigated 760 patients with gastric cancer since the beginning of 1993 to the end ...
Microfluidic continuous cell separation based on hydrodynamic interaction in a microfluidic channel has attracted attention because of its robustness, high throughput and cell viability. This paper systematically gives an overview on recent advances in hydrodynamic particle and cell separation in microfluidic devices. It presents the basic ideas and fluid mechanics for the hydrodynamic interact...
This study was conducted to evaluate the influence of exogenous supplement Natuzime plus enzyme on growth performance, body composition and survival rate of beluga (Huso huso) juveniles. Juveniles (n = 17 fish per each tank with initial weight of 30 g) were randomly distributed in 150-L tanks and fed with four diets (each in three replicates) containing 0, 2, 5 and 10 % of Natuzime plus multi ...
conclusions parametric models may provide complementary data for clinicians and researchers about how risks vary over time. the weibull model seemed to show the best fit among the parametric models of the survival of hemodialysis patients. results the results of a multivariate analysis of the variables in the parametric models showed that the mean serum albumin and the clinic attended were the ...
The aim of this study was to determine the effect of anthocyanin from roselle (Hibiscus sabdariffa) supplemented diets on growth, survival and body composition of rainbow trout (Oncorhynchus mykiss) for 60 days. Fish were fed 0 % (control), 0.5 %, 1 % and 2 % anthocyanin extract in complete random design. Fifteen fish with the same initial weight (14 ± 0. 1 g) were selected and randomly distr...
