Music is one of the strongest triggers of emotions. Recent studies have shown strong emotional predispositions for musical instrument timbres. They have also shown significant correlations between spectral centroid and many emotions. Our recent study on spectral centroid-equalized tones further suggested that the even/odd harmonic ratio is a salient timbral feature after attack time and brightn...

objectives: the current study was performed to investigate the relationship between mental impairment and each component of activity of daily living (adl) in elderly residents of the kahrizak charity foundation. methods & materials: standardized iranian mini mental examination and barthel index were used to assest cognitive status and adl in 184 elderly residents of kahrizak, respectively. resu...

introduction: during the past few years, an increasing body of evidence has suggested a possible role for human herpes virus 6 (hhv-6) in multiple sclerosis (ms) pathogenesis. despite the many reports supporting the relationship between hhv-6 and ms, this association has not been definitely proved or refuted, and the matter remains unresolved. the current study was aimed to investigate any rela...

In this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. Let G = (V,E) be a graph with p vertices and q edges. G is said be skolem odd difference mean if there exists a function f : V (G) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : E(G) → {1, 3, 5, . . . , 2q−1} de...

AIM OF THE STUDY This study tried to identify risk factors of aggressive behavior in a population of schizophrenic inpatients. We tested the association between aggressive behavior and socio-demographic characteristics, addictive disorders, history of suicide attempt, and sexual violence, impulsivity, and sensation seeking. METHODS All consecutive schizophrenic inpatients (100) were assessed ...

background : plasmodium falciparum infection is endemic in most tropical countries and will definitely infect human immunodeficiency virus (hiv) positive patients living in this region at one time or the other during the course of their infection. this study was conducted to determine the prevalence of malaria infection in hiv-infected patients on highly active antiretroviral therapy in benin c...

to evaluate the effectiveness of a relapse prevention cognitive-behavioral model, based on marlatt treatment approach, in opioid-dependent patients participating in the methadone maintenance treatment (mmt) in iran.the study consisted of 92 individuals treated with methadone in iranian national center of addiction studies (incas). participants were randomized into two groups: educational interv...

If qα is the Euler factor of an odd perfect number N, then we prove that its so-called index σ(N/qα) � qα ≥ 32 × 5× 7 = 315. It follows that for any odd perfect number, the ratio of the non-Euler part to the Euler part is greater than 32 × 5× 7/2.

In this paper, we investigate the ratio of numbers odd and even cycles in outerplanar graphs. We verify that generally diverges to infinity as order a graph infinity. also give sharp estimations for several classes graphs, obtain constant upper bound some them. Furthermore, consider similar problems graphs with pairs forbidden subgraphs/minors, propose challenging problem concerning claw-free
