Main text Extending visiting hours in adult intensive care units (ICUs) promotes family-centered care, but physicians may be concerned about increased distractions from visitors [1]. We sought empirical evidence within our 20-bed medical ICU, assuming that distractions could cause medical errors [2]. During office hours (07.30 to 17.30 on weekdays; 07.30–12.30 on weekends), two physician teams ...

The new curve contains all of the information about the original curve’s tangent lines. For example, it crosses the y-axis whenever the original curve has a horizontal tangent line. The straight line y = mx + b, or (x(t), y(t)) = (t,mt + b), has only one tangent line and thus a trivial transformation to a point, (x∗(t), y∗(t)) = (m, b). Some conic sections transform to conic sections. For examp...

Let be a positive measure on the real line, with orthogonal polynomials fpng and leading coe¢ cients f ng. The Geronimus type identity 1 jIm zj Z 1 1 P (t) jzpn (t) pn 1 (t)j dt = n 1 n Z P (t) d (t) ; valid for all polynomials P of degree 2n 2 has known analogues within the theory of orthogonal rational functions, though apparently unknown in the theory of orthogonal polynomials. We present ne...

BACKGROUND Cicatricial alopecia encompasses a diverse group of disorders characterized by the permanent destruction of hair follicles and irreversible hair loss. Follicular unit transplantation was developed in 1994. However, large-scale clinical trials are necessary to study follicular unit transplantation for treating Chinese cicatricial alopecia patients. OBJECTIVE To investigate the effic...

The primary objective of this study is to develop a numerical scheme for accurate and eecient simulation of phase change and transport processes of industrial importance. These processes may include a variety of heat transfer and ow mechanisms in irregularly shaped domains with moving and/or free boundaries. Based on the multizone adaptive grid generation (MAGG) technique 1], a curvilinear nite...

transfer of patients from the cardiac intensive care unit to the general ward, is one of the main reasons for anxiety. given that the transfer anxiety may be due to receive at least, inconsistent or do not receive enough information before the patients leaving the intensive care unit, therefore, this study aimed to determine the effect of information provision on anxiety levels in patients tran...

Background & Aims: Exposure Keratitis (EK) is a common problem in critically ill patients admitted to the Intensive Care Unit (ICU). We conducted exposure keratitis in mechanical ventilatory patients in the intensive care unit of Imam Khomeini Hospital in Urmia for five years. Materials & Methods: In this retrospective cross-sectional study, the records of the patients were taken from the medi...

Abstract The study of analytic semiflows on the open unit disc and the particular form of its infinitesimal generator G makes possible the study of semigroups of composition operators (T (t))t≥0 on various well-known spaces of holomorphic functions such as Hardy, Dirichlet and Bergman spaces. We will provide compactness, analyticity and invertibility complete characterization of (T (t))t≥0 in t...

objective: professional nursing is recognised for having high working anxiety levels due to continuous interaction with patients, their family and colleagues in a high stress working environment. as a compilation of non cognitive skills and abilities, emotional intelligent could be helpful in controlling stress and increasing the individual’s productivity at work. intensive care units’ employee...

the issue of unit commitment is one of the most important economic plans in power system. in modern and traditional power systems, in addition to being economical of the planning, the issue of security in unit operation is also of great importance. hence power system operation confronts units’ participation and input considering network security constrains. the issue of units’ participation is ...
