Nearly a century has passed since the establishment of nursing education programs in Iran. The first nursing school was established in 1916 (1294 Solar Hijri) in Urmia and moved to Tabriz after a year due to the World War. Also, nursing research in Iran has a history of nearly half a century. Nursing research in Iran first began independently in 1970s (1350s SH) with starting admission i...
مقدمه: تصمیمگیری در مورد تعداد فرزند مدنظر، یکی از مهمترین وقایع چرخۀ زندگی خانوار است که آثار و عواقب مهمی را در پی دارد که یکی از آنها، وضعیت سلامت فرزندان است. هدف مطالعه این است تا مشخص شود آیا میان تعداد و سلامت فرزندان رابطهای برقرار است؟ درصورت مثبت بودن پاسخ، تعیین تعداد فرزندان نمیتواند فارغ از در نظر داشتن وضعیت سلامت آنها باشد. روش: استدلال قیاسی، روش تحلیل مسئله در این مطالعه ر...
Silvopasture, the combination of trees, forage, and livestock, is a management practice that gaining interest throughout southeastern U.S. This research analyzed hay-based alley cropping field trial transitioning into silvopasture system. We planted four different tree spacings—2.4 × 2.4 m, 3.0 1.8 m (8 8 ft, 10 10ft, 6 ft)—of loblolly pine (Pinus taeda L.) used secondary data for possible plan...
BACKGROUND Although prostate cancer is one of the most common male cancers, its aetiology-and particularly the role of comorbidity-remains poorly understood. PATIENTS AND METHODS Between 1991 and 2002, a case-control study on prostate cancer was conducted in Italy. This included 1294 men under the age of 75 years with incident, histologically confirmed prostate cancer, and 1451 controls, admi...
Li2S has a high theoretical capacity of 1166 mAh g(-1), but it suffers from limited rate and cycling performance. Herein we reported in-situ synthesis of thermally exfoliated graphene-Li2S (in-situ TG-Li2S) nanocomposite and its application as a superior cathode material alternative to sulfur. Li2S nanoparticles with the size of ~8.5 nm homogeneously anchored in graphene nanosheets were prepare...
Nitrate in serum and urine was assayed by a modification of the cadmium-reduction method; the nitrite produced was determined by diazotization of sulfanilamide and coupling to naphthylethylene diamine. After samples were deproteinized with Somogyi reagent, the nitrate was reduced by Cu-coated Cd in glycine buffer at pH 9.7 (2.5 to 3 g of Cd granules for a 4-mL reaction mixture). The reduction f...
We review theoretical work on global oscillations of Be star disks and summarize possible observational tests. In addition, we analyze existing records on photometric data andV/R ratio for a sample of 6 V/R variable Be stars. Five stars showed coupled long-term photometric-V/R variations. In all cases the photometric extrema coincided with times of V = R transits, the fainter state being follow...
Background In T1DM, delayed pubertal development and reduced final height are associated with inadequate metabolic control. Objective To assess whether T1DM affects pubertal growth spurt and whether metabolic control during puberty is gender-related. Methods Using a large multicentre database, longitudinal data from 1294 patients were analysed. Inclusion criteria: complete records of height...
Posttranslational modification is critical for the function of the gene products of ras oncogenes, which are frequently mutated in cancer. Ras proteins are modified by farnesyltransferase (FTase), but many related small GTPases that also end in a CAAX motif (where C is cysteine, A is often an aliphatic amino acid, and X is any amino acid) are modified by a closely related enzyme known as gerany...
Sleep deficiency is a significant issue across higher education campuses and has a detrimental effect on students’ academic achievement, physical and mental health, and overall wellbeing. The purpose of this study was to carry out a campus-wide survey determining students’ self-reported sleep patterns, sources of advice for sleep problems, current sleep promoting practices, and preferred mechan...
