نانوسیم های آلیاژی nicu به روش الکترونهشت پالسی نامتقارن بر روی زیرلایه ی zn در قالب آلومینای آندی تهیه شده به روش آندیزاسیون سخت ساخته شد. با استفاده از الکترولیت های با غلظت مختلف cu2+و همچنین تغییر ولتاژ کاهش الکتروشیمیایی نانوسیم های x-1 nixcu با 5/0 -25/0 x = و قطر حدود 50 نانومتر به دست آمد. نتایج اندازه گیری اشعه ی x نشان داد که در نمونه های مورد بررسی دو فاز بلوری مرکز وجهی نیکل و فاز ب...
PURPOSE The purpose of this study was to conduct a comparative analysis between the perception of parents with premature infants in the NICU and parents with full-term newborns, and in the process to evaluate the effects of NICU educational support on parents with regard to their perception of neonate and parental stress. METHODS A mixed quantitative design was employed to compare parental pe...
Background. Mothers of infants admitted to a neonatal intensive care unit (NICU) are believed to have heightened distress. The purpose of this paper was to determine depression and anxiety symptoms and attachment style in NICU mothers. Methods. The NICU group consisted of mothers whose infants were admitted to the NICU and the control group consisted of mothers of healthy term infants. The psyc...
OBJECTIVE To compare the psychosocial functioning of the parents (mother and father) of infants admitted to a neonatal intensive care unit (NICU) with the parents of infants born at term and not admitted to the NICU. DESIGN Random sample of NICU parents and term non-NICU parents were assessed across a variety of psychiatric and psychosocial measures shortly after the birth of their infant. ...
در این تحقیق نانوسیمهای آلیاژی cocu و nicu درون حفره های قالب پلی کربنات با قطر اسمی 30nm به روش الکتروانباشت تهیه شدند. به منظور رشد نانوسیمهای cocu و nicu به ترتیب از دو الکترولیت مجزای حاوی نمکهای co، cu وni ، cu استفاده شد. برای بررسی رفتار پتانسیودینامیکی الکترولیتها و تعیین ولتاژ بهینه انباشت، منحنی cv مربوط به هر یک از الکترولیتها تهیه و مورد مطالعه قرار گرفت. ساختار نانوسیمها با استفاد...
The goal was to identify sound pressure level (SPL) at the neonatal intensive care unit (NICU) and inside the incubator of a teaching hospital of a public university from São Paulo - SP, Brazil. SPL inside the NICU and the incubator were measured using four dosimeters in January/2010. SPL at the NICU varied from 52.6 dBA to 80.4 dBA and inside the incubator, from 45.4 dBA to 79.1 dBA. SPL both ...
OBJECTIVE In 1976, the Committee on Perinatal Health recommended that hospitals with no neonatal intensive care unit (NICU) or intermediate NICUs transfer high-risk mothers and infants that weigh <2000 g to a regional NICU. This standard was based on expert opinion and has not been validated carefully. This study evaluated the effect of NICU level and patient volume at the hospital of birth on ...
OBJECTIVES To determine whether newborn hearing screening in a well-baby nursery (WBN) and neonatal intensive care unit (NICU) nursery: 1) meet three targeted, screening, referral, and diagnostic follow-up rates; 2) compare the average age of diagnosis for infants admitted to the WIN and NICU; and 3) determine prevalence of hearing loss in neonatal population; and 4) try to find a practical new...
Neonatal intensive care units (NICUs) and intensive care units (ICUs) provide care for newborns in need of specialized medical attention. Across Canada, rates of NICU/ICU admission vary. Due to the high cost of monitoring and interventions these admissions cost more than general newborn stays - whether the newborn is in a specialized NICU or in an ICU in those facilities without specialized uni...
