koorosh Holakooyi Naeini,Reza Chaman,Abbas Rahimi,Masoomeh Javaheri
Knowledge & Health Journal , 2010,
Abstract: Introduction: Influenza pandemic H1N1 is an acute respiratory infectious disease that is combination of two types of influenza virus type A (H1N1). This study aimed to identify risk factors affecting influenza pandemic H1N1. Methods: In this case-control study, the cases were 18 positive cases of pandemic influenza H1N1 and the controls were the patients who were admitted during the same time as the cases to sections of Orthopedics, Urology, Surgery and Women of the same hospital for reasons other than influenza. The data were collected through a form by two experienced nurses and then were fed into SPSS, and were analyzed using independent T-test and chi-square. Results: A significant relationship was observed between pandemic H1N1 influenza infection and a history of domestic travel, contact with confirmed patients, respiratory diseases, and diabetes (P0.05). Conclusion: People with underlying diseases, especially respiratory diseases, diabetes, heart disease and a secondary infection and cardiovascular disease most likely are susceptible to influenza pandemic H1N1.
Effectiveness Life Review on Life Satisfaction among Adolescents under the Supervision of Qazvin Well-Being Center  [PDF]
Masoomeh Esmaeili, Ahmad Usefynezhad
Open Journal of Psychiatry (OJPsych) , 2016, DOI: 10.4236/ojpsych.2016.61001
Abstract: Objective: The aim of this study was to determine Effectiveness Life Review on Life Satisfaction among Adolescents under the Supervision of Qazvin Well-being Center 2012-2013. Method: This study was a quasi-experimental research including experimental and control groups with a pretest-posttest design. The statistical population consisted of all 12 - 18 years old male students who were nurtured in Qazvin Well-being Center, among whom 16 individuals were selected through applying purposive sampling method and were randomly divided into experimental and control groups with equal number of subjects. The investigation was done using Diener’s (1985) Satisfaction with Life Scale (SWLS) Questionnaire. The experimental group received life review therapyin 6 sessions (90 minutes per session). Data were analyzed by using Analysis of Covariance(ANCOVA), using SPSS software. Results: Results indicated that life review therapywas effectivein increasing male adolescents’ life satisfaction living in the welfare center. Conclusion: Life review therapy improves quality of life and life satisfaction; therefore, this treatment can be used as an effective method to improve the living conditions of young people.
Treatment of obstructive and central sleep apnoea in heart failure: practical options
S. Javaheri
European Respiratory Review , 2007,
Abstract: Sleep apnoea, both central and obstructive disordered breathing, commonly occurs in patients with heart failure. Obstructive sleep apnoea occurs both in systolic and diastolic heart failure and is best treated with nasal positive airway pressure devices. Central sleep apnoea occurs primarily in systolic heart failure and therapeutic options are evolving. Optimal therapy of systolic heart failure, nocturnal use of supplemental oxygen, theophylline, acetazolamide and positive airway pressure devices have been shown to improve central sleep apnoea. Among these therapeutic modalities only continuous positive airway pressure has been studied in a long-term trials; unfortunately, it failed to improve survival.
Harmonic functions via restricted mean-value theorems
Mohammad Javaheri
Mathematics , 2007,
Abstract: Let $f$ be a function on a bounded domain $\Omega \subseteq \mathbb{R}^n$ and $\delta$ be a positive function on $\Omega$ such that $B(x,\delta(x))\subseteq \Omega$. Let $\sigma(f)(x)$ be the average of $f$ over the ball $B(x,\delta(x))$. The restricted mean-value theorems discuss the conditions on $f,\delta,$ and $\Omega$ under which $\sigma(f)=f$ implies that $f$ is harmonic. In this paper, we study the stability of harmonic functions with respect to the map $\sigma$. One expects that, in general, the sequence $\sigma^n(f)$ converges to a harmonic function. Among our results, we show that if $\Omega$ is strongly convex (respectively $C^{2,\alpha}$-smooth for some $\alpha\in [0,1]$), the function $\delta(x)$ is continuous, and $f\in C^0(\bar \Omega)$ (respectively, $f\in C^{2,\alpha}(\bar \Omega)$), then $\sigma^n(f)$ converges to a harmonic function uniformly on $\bar \Omega$.
Line crossing problem for biased monotonic random walks in the plane
Mohammad Javaheri
Mathematics , 2007,
Abstract: In this paper, we study the problem of finding the probability that the two-dimensional (biased) monotonic random walk crosses the line $y=\alpha x+d$, where $\alpha,d \geq 0$. A $\beta$-biased monotonic random walk moves from $(a,b)$ to $(a+1,b)$ or $(a,b+1)$ with probabilities $1/(\beta + 1)$ and $\beta/(\beta + 1)$, respectively. Among our results, we show that if $\beta \geq \lceil \alpha \rceil$, then the $\beta$-biased monotonic random walk, starting from the origin, crosses the line $y=\alpha x+d$ for all $d\geq 0$ with probability 1.
Lower bounds for warping functions on warped-product AHE manifolds
Mohammad Javaheri
Mathematics , 2007,
Abstract: Let $[\gamma]$ be the conformal boundary of a warped product $C^{3,\alpha}$ AHE metric $g=g_M+u^2h$ on $N=M \times F$, where $(F,h)$ is compact with unit volume and nonpositive curvature. We show that if $[\gamma]$ has positive Yamabe constant, then $u$ has a positive lower bound that depends only on $[\gamma]$.
A Collatz-type conjecture on the set of rational numbers
Mohammad Javaheri
Mathematics , 2010,
Abstract: Define $\theta(x)=(x-1)/3$ if $x\geq 1$, and $\theta(x)=2x/(1-x)$ if $x<1$. We conjecture that the orbit of every positive rational number ends in 0. In particular, there does not exist any positive rational fixed point for a map in the semigroup $\Omega$ generated by the maps $3x+1$ and $x/(x+2)$. In this paper, we prove that the asymptotic density of the set of elements in $\Omega$ that have rational fixed points is zero.
O-segments on topological measure spaces
Mohammad Javaheri
Mathematics , 2008,
Abstract: Let $X$ be a topological space and $\mu$ be a nonatomic finite measure on a $\sigma$-algebra $\Sigma$ containing the Borel $\sigma$-algebra of $X$. We say $\mu$ is weakly outer regular, if for every $A \in \Sigma$ and $\epsilon>0$, there exists an open set $O$ such that $\mu(A \backslash O)=0$ and $\mu(O \backslash A)<\epsilon$. The main result of this paper is to show that if $f,g \in L^1(X,\Sigma, \mu)$ with $\int_X f d\mu=\int_X g d\mu=1$, then there exists an increasing family of open sets $u(t)$, $t\in [0,1]$, such that $u(0)=\emptyset$, $u(1)=X$, and $\int_{u(t)} f d\mu=\int_{u(t)} g d\mu=t$ for all $t\in [0,1]$. We also study a similar problem for a finite collection of integrable functions on general finite and $\sigma$-finite nonatomic measure spaces.
Chord theorems on graphs
Mohammad Javaheri
Mathematics , 2007,
Abstract: The Horizontal Chord Theorem states that if a continuous curve connects points $A$ and $B$ in the plane, then for any integer $k$ there are points $C$ and $D$ on the curve such that $\overrightarrow{AB}=k \overrightarrow{CD}$. In this note, we discuss a few combinatorial-analysis problems related to this theorem and introduce a different formulation that gives way to generalizations on graphs.
Semigroups of real functions with dense orbits
Mohammad Javaheri
Mathematics , 2009,
Abstract: Let ${\mathcal F}_I=\{f:I \to I| f(x)= (Ax+B)/(Cx+D); AD-BC \neq 0 \}$, where $I$ is an interval. For $x\in I$, let ${\Omega}_x$ be the orbit of $x$ under the action of the semigroup of functions generated by $f,g \in {\mathcal F}_I$. Our main result in this paper is to describe all $f,g \in {\mathcal F}_I$ such that $\Omega_x$ is dense in $I$ for all $x$.
