introduction: cesarean surgical site infection (ssi) occurs in 3% to 17% of patients who undergo cesarean delivery. ssis increase postcesarean maternal morbidity and health costs and cause longer hospital stays. therefore, we designed a study to assess the effects of normal saline and cefazolin irrigation on the incidence of ssis. methods: in this study, 200 participants were divided into 3 gro...

normal pressure hydrocephalus (nph) is characterized by gait apraxia, urinary incontinence, and dementia. mixed connective tissue disease (mctd) is an autoimmune connective tissue disease that has never been reported to cause nph. our patient was a 67-year man with a one-year history of gradual worsening gait and balance, urinary urgency with urge incontinence and decreased short-term memory. p...

normal 0 false false false en-us x-none ar-sa background : routine episiotomy is a controversial issue among gynecologists. the aim of this study was to compare early maternal and neonatal complications of restrictive episiotomy and routine episiotomy in primiparus vaginal delivery. methods : in this descriptive cross-sectional study, two groups of primiparus normal vaginal delivery (nvd) cases...

background: we aimed to compare the effect of albumin 5% in half normal saline (half ns) versus normal saline (ns) infusion on the plasma viscosity in the near-normal physiological condition. according to the high oncotic pressure of albumin along with prolonged half-life of its molecules in comparison to ns in the intra-vascular compartment, it has been proposed that a more significant reducti...

in this descriptive study, we investigated how mother and infant rooming method after delivery are implementing in academic hospitals of tehran university of medical sciences in 1993. in this research, fifteen wards include post delivery ward, surgical ward that mothers after cesarean section hospitalized in them and jointed ward that mothers who underwent cesarean section and normal vaginal de...

We study the magnetic Laplacian in the case when the Neumann boundary contains an edge. We provide complete asymptotic expansions in powers of h of the low lying eigenpairs in the semiclassical limit h→ 0. In order to get our main result we establish a general method based on a normal form procedure, microlocal arguments, the Feshbach-Grushin reduction and the Born-Oppenheimer approximation.

Representation and reasoning about dynamic spatial phenomena requires at its foundation a formalism of spatial change. This paper extends our understanding of topological change, by providing a classification and analysis of events associated with changes in topological structures of spatial areal objects as they evolve through time. Tree structures are employed to represent topological relatio...

The centrepiece of this paper is a normal form for primitive elements which facilitates the use of induction arguments to prove properties of primitive elements. The normal form arises from an elementary algorithm for constructing a primitive element p in F(x, y) with a given exponent sum pair (X, Y ), if such an element p exists. Several results concerning the primitive elements of F(x, y) are...

Using an appropriate notion of equivalence, those classical Hamiltonian systems which admit a first integral of motion polynomial of degree one in momentum are classified. The classification is effected by means of finding a normal form for a skew-symmetric matrix under the action of orthogonal symmetry.
