due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. the known world class cu-mo deposit, sarcheshmeh porphyry deposit (central iran) selected as the study area. the hypogene zone of the deposit was chosen as the space in which estim...

We present a study of a sample of LMC red giants exhibiting Long Secondary Periods (LSPs). We use radial velocities obtained from VLT spectral observations and MACHO and OGLE light curves to examine properties of the stars and to evaluate models for the cause of LSPs. This sample is much larger than the combined previous studies of Hinkle et al. (2002) and Wood, Olivier & Kawaler (2004). Binary...
In this study, we analysed IgG avidity to p 15.5 kD, p 17 kD and p 47 kD antigens by a new avidity assay termed avidity western blot. The determination was performed in two groups. Group I consisted of 27 patients with primary and secondary syphilis and group II comprised 10 subjects with latent syphilis. We found that low avidity antibodies were directed against the p 17 kD and p 47 kD antigen...
Purpose: Self-efficacy as a part of self refers to belief and confidence to one's abilities to achieve goals and tasks. Therefore, the aim of this study was investigating the impact of curriculum literacy and media literacy on job self-efficacy in secondary school teachers. Methodology: The method of research was descriptive from type of correlation. The statistical population in this study we...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
ABSTRACT Pulmonary hypertension is one of the causes of cyanosis in children. Pulmonary hypertention may be primary or secondary. Etiology of secondery PH are variable and one of them is pulmonary ventilation abnormality. One of the rare causes of secondary PH is congenital central hypoventilation syndrome or ondines curse. The patient was 6 years old boy presented with easy fati...
