conclusions the results of our study showed that non-albicans species of candida are more frequent than c. albicans in patients with vvc. this result is in line with some recent studies indicating that non-albicans species of candida must be considered in gynecology clinics due to the reported azole resistance in these species. results out of 234 patients with vulvovaginitis, 66 (28.2%) patient...
objectives the current study aimed to determine the incidence of neonatal infection (nicus) in south sinai neonatal intensive care units, egypt. methods the study included 1023 neonates admitted to neonatal intensive care units in the south sinai state hospitals from january 2010 to september 2014 and scanned for demographic data and the potential risk factors for neonatal septicemia. results t...
Quality control of textile products is an important stage in textile industries. To this end, the conventional method in fault detection is human inspection. In the present work, Wavelet transform was applied on images of simple circular knitted fabrics to diagnose five regular defects. The results showed that the method applied was accurate and fast in addition to being capable of determining ...
This paper investigates the incentive effects of automobile insurance, compulsory insurance laws, and no-fault liability laws on driver behavior and traffic fatalities. We analyze a panel of 50 U.S. states and the District of Columbia for 1970–98, a period in which many states adopted compulsory insurance regulations and/or nofault laws. Using an instrumental variables approach, we find evidenc...
background: cancer is the third cause of death in iran and its incidence is rising alarmingly. however, a study reported that kohgilooyeh and boyerahmad (a small province in iran) seems to have substantially lower incidence rate of cancer compared to the other parts of the country. this study is conducted to investigate the epidemiological features of cancer regarding three key factors (sex, ag...
background: the induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. in developing countries 94% of human radiation is from natural sources. in iran some high altitude regions such as, chaharmahal & bakhtiari has high levels of the natural background radiation (higher than the worldwide average). therefore, investigation o...
the purpose of this study was to investigate the incidence of different types of skin diseases among 657 children who were seen during one year period (oct. 1971-setp. 1972) at the skin clinics of the isfahan university hospital. the incidence of different types of skin disease was compared with those of the adults. in general this study shows that in isfahan area the incidence of skin infectio...
objective neonates, for many reasons, are at particular risk for the development of seizures, which are a strong predictor of later morbidity and mortality in infants. we undertook this study to determine the incidence, etiologic distribution and neonatal seizure type in neonates with hospital admission over a period of 4 years. materials and methods this, a retrospective study of newborns admi...
iran is one the most tectonically active parts of the world and regularly experiences earthquakes of both low and high magnitude. therefore, earthquake hazard assessment before any kind of building construction and for already built and populated area is essential. a vital first step in this type of study is to identify, map, and determine the activity of faults within a given region. investiga...
Superconductor fault current limiter (SFCL) is an effective device to suppress high fault currents. This paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view. Appropriate location and type of the limiters in a HV substation is selected by a qualitative approach based on the equal area criterion. Study system is simulated by...
