Using the concept of s-formality we are able to extend the bounds of a Theorem of Miller and show that a compact k-connected 4k + 3or 4k + 4-manifold with bk+1 = 1 is formal. We study simply-connected 7and 8-manifolds with a hard Lefschetz-like property and prove that in this case if b2 = 2, then the manifold is formal, while, in 7-dimensions, if b2 = 3 all Massey products vanish. We finish wit...

introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

this paper is an investigation of $l$-dual frames with respect to a function-valued inner product, the so called $l$-bracket product on $l^{2}(g)$, where g is a locally compact abelian group with a uniform lattice $l$. we show that several well known theorems for dual frames and dual riesz bases in a hilbert space remain valid for $l$-dual frames and $l$-dual riesz bases in $l^{2}(g)$.

background: respiratory problem is one of the major health hazards in dust-exposed workers; it is a major cause of morbidity and mortality all over the world. objective: to determine the prevalence of respiratory problems and lung function impairment among quarry workers in ebonyi state, nigeria. methods: respiratory problems and lung function were studied in 403 quarry workers aged 10–60 years...

we establish a sharp maximal function estimate for some vector-valued multilinear singular integral operators. as an application, we obtain the $(l^p, l^q)$-norm inequality for vector-valued multilinear operators.

This paper will define the random walk on an integer lattice and will approximate the probability that the random walk is at a certain point after a certain number of steps by using a modified version of the Central Limit Theorem. To accomplish this, we will define the characteristic function of the random walk, find the Taylor expansion of this function, and bound the difference between this f...

background: increase in world population is one of the serious and threatening issues in this century. therefore, it is vitally important to find safe and effective contraceptive methods, especially for men which already have few choices in this regard. medicinal plants that were used for contraception in ancient times could be good sources of investigation in this filed. ruta graveolens l. is ...
