abstract. in this paper, we classify all of the finite p-groups with at most three non linear irreducible character kernels.

in this paper, we give some characterizations for legendre spherical, legendre normal and legendre rectifying curves in the 3-dimensional sasakian space. furthermore, we show that legendre spherical curves are also legendre normal curves. in particular, we prove that the inverse of curvature of a legendre rectifying curve is a non-constant linear function of the arclength parameter.

this paper investigates the dynamics and stability properties of a discrete-time lotka-volterra type system. we first analyze stability of the fixed points and the existence of local bifurcations. our analysis shows the presence of rich variety of local bifurcations, namely, stable fixed points; in which population numbers remain constant, periodic cycles; in which population numbers oscillate amo...

abstract background: coherent scattering leads to diffraction effects and especially constructive interferences. theseinterferences carry some information about the molecular structure of the tissue. as breast cancer isthe most widespread cancer in women, this project evaluated the application of small anglex-ray scattering (saxs) for differentiation between normal and cancerous breast tissues....

curcumin is a natural substance with anti-cancerous properties without many disadvantages of currently-used anticancer drugs. its toxicity is significantly higher in tumor cells compared with normal cells. we hypothesized the difference of p53 function between normal and tumor cells as one of the presumable causes of this phenomenon. we knocked down the expression of p53 in normal fibroblasts u...

introduction: acute kidney injury (aki) is a common postoperative complication of cardiac surgery, which is associated with an increased risk of morbidity and mortality. this study investigated the frequency of postoperative aki in low risk adult patients undergoing off-pump coronary artery bypass grafting (cabg).materials & methods: all consecutive adult patients of american society of anesthe...

abstract background: the functions and use of mouthwashes are variable depending on their type. oral care in patients with endotracheal tubes is important to prevent side effects such as pneumonia. the aim of this study was to determine the antimicrobial effects of chlorhexidine, drop of matrica mouthwash (chamomile extract), and normal saline on hospitalized patients with endotracheal tube in ...

objective: theory of mind (tom) or mindreading is an aspect of social cognition that evaluates mental states and beliefs of oneself and others. validity and reliability are very important criteria when evaluating standard tests; and without them, these tests are not usable. the aim of this study was to systematically review the validity and reliability of published english comprehensive tom tes...

introduction: newborns should be evaluated immediately after birth and the traditional way of assessing is to use the apgar score. the aim of this study was to estimate the apgar score and evaluate the first 24 hour- clinical outcome of babies born at yazd hospitals. methods: in a descriptive cross-sectional study, apgar score was assessed for 462 newborns at the 4 centers of afshar, madar, kar...
