The freshwater angel fish (Pterophyllum scalare Schultze, 1823) is South American cichlid become very popular among aquarists. There is little information on their culture and aquarium husbandry. In this study growth performance and survival rate of angelfish subjected to different feeding frequencies were evaluated. Four groups of angel fish juveniles (0.87 ± 0.01 g; 3.98 ± 0.08 mm) were fed e...

The Acehnese mahseer, locally known as keureling, Tor tambra is one of the highest economically valued freshwater fishes found in Aceh waters. The culture of T. tambra was initiated in Aceh Province, Indonesia more than five years ago. However, the growth rate in captivity has been low, probably due to feeding problems. Hence, the objective of the present study was to evaluate the optimum level...

MOTIVATION New application areas of survival analysis as for example based on micro-array expression data call for novel tools able to handle high-dimensional data. While classical (semi-) parametric techniques as based on likelihood or partial likelihood functions are omnipresent in clinical studies, they are often inadequate for modelling in case when there are less observations than features...

length-biased data are widely seen in applications. they are mostly applicable in epidemiological studies or survival analysis in medical researches. here we aim to propose a berry-esseen type bound for the kernel density estimator of this kind of data.the rate of normal convergence in the proposed berry-esseen type theorem is shown to be o(n^(-1/6) ) modulo logarithmic term as n tends to infin...

paratesticular sarcomas have happened rarely. due to the infrequency of this malignant disease and its diverse histopathologic subtypes, no standard treatment would be available. multiple treatments have reported in literature with different results. we have reported a 55 years old man with a 30 years history of paratesticular mass. after multiple operations, radical orchiectomy has revealed li...

background: breast cancer is the most common cancer and the leading cause of cancer death among the women worldwide. the risk of local and distant recurrence is the highest during the first two years following the initial treatment. very late relapse (after 12 years) is uncommon in breast cancer survivors. methods: herein, we report the characteristics and outcomes of 6 such cases of breast can...

background : iud is one of the safest and most widely used reversible methods of contraception. the purpose of this study was to determine iud survival and reasons for early discontinuation in bandar abbas, south of iran. methods: probability of iud continuation rate and factors associated with discontinuation were assessed in a historical cohort study of 400 women records from march 2002 to fe...

background: population based research contributes to our understanding of cancer at many levels. for health program planning and policy making it is important to have information about the incidence of the common cancers in the population. descriptive epidemiologic studies measure the occurrence of cancer and other health-related factors in relation to person (e.g. age, sex, race, social class,...
