background: vaginal sonograghy and serial -hcg are the most common diagnostic methods for ectopic pregnancy but about 50% of cases are initially misdiagnosed. in tubal pregnancy the zygote lies next to the muscular layer, and this invasion causes an increase in creatine phosphokinase (cpk) in blood. objective: assessment of cpk and its isoenzyme cpk-mb as a diagnostic marker for tubal pregnanc...
introduction zayanderood basin is one of the major internal river basins in the central iran, where zayanderood river is the only permanent river. fluctuations in rainfall in recent years have affected different areas of iran. because of the dependence of the provinces of isfahan, yazd, and kerman on water resources of this basin, changes and fluctuations in precipitation within this watershed ...
A comparatively unbiased set of wind statistics at jet-stream level from Japan eastward to the 180th meridian may be obtained from the United States Navy constant level balloon (transosonde) flights launched from Japan in 1957-59. Wind speeds so derived are presented as a function of time of year and longitude at pressure surfaces of 300 and 250 mb. At these longitudes and heights the average s...
Context. NGC 300 X-1 is the second extragalactic candidate, after IC 10 X-1, in the rare class of Wolf-Rayet/compact object X-ray binary systems exemplified in the Galaxy by Cyg X-3. From a theoretical point of view, accretion onto a black hole in a detached system is possible for large orbital periods only if the mass of the relativistic object is high or the velocity of the accreted wind is l...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
چکیده diphyllidea van beneden in carus, 1863 راسته ای است از رده eucestoda که گونه های آن همگی تنها در دریاها زیست کرده و از گونه های مختلف سفره ماهی و یک خانواده از کوسه ماهیان به عنوان میزبان نهایی استفاده می کنند. در این مطالعه گونه ای جدید از جنس coronocestus caira, marques, jensen, kuchta and ivanov, 2013 متعلق به راسته diphyllidea از یک گونه کوسه ماهی به نام iago omanensis (norman) از د...
هدف تحقیق حاضر بررسی تاثیر نشانه های فرا گفتمان متنی بر فهم متون انگلیسی به وسیله ی زبان اموزان فارسی زبان است.این تحقیق علاوه بر این کوشیده است تا میزان اگاهی این زبان اموزان و نحوه ی تعامل انان را با متون خوانده شده در زبان انگلیسی به وسیله ی پرسش نامه ی تهیه شده بررسی کند.بر اساس محتوای یک متن انگلیسی یازده سوال درست /غلط طرح گردید و یک مرتبه با ان متن و یک مرتبه با نسخه ای که نشانه ها...
