introduction: the purpose of this study was to investigate the effect of 6w power carbon dioxide laser (co2) on the biologic compatibility of the sandblasting with large grit and acid etching (sla) titanium discs through studying of the sarcoma osteogenic (saos-2) human osteoblast-like cells viability. methods: sterilized titanium discs were used together with saos-2 human osteoblast-like cells...

Background and objective: Nutrition and physical activity are two factors which affecting the control of body composition and cardiorespiratory fitness in the elderly population. Present study aimed to investigate the effects of continued training (CT) and high intensity interval training (HIIT) along with Citrus aurantium (Ca) on aerobic power and body composition of elderly rats. Material An...

In this paper the effect of plasma spray parameters, atomizing gas and substrate preheat temperature on microstructure and phase composition of YSZ coatings produced by SPPS process have been investigated. The experimental results showed that increasing the power of plasma, using hydrogen as the precursor atomizing gas and increasing substrate preheat temperature decrease the amount of non-pyro...

the effect of oleic acid (5 and 10% v/v) and xanthan gum (0.5 and 1% wt) on  partitioning and retention of ethyl acetate and diacetyl from two matrices with a different composition was investigated by applying static head space gas chromatography. two matrices with different composition have been developed: one containing carbohydrates (xanthan gum) and in the second one, called complex matrix,...

In this article, we discuss measure theoretic characterizations for weighted composition operators in some operator classes on $L^{2}(Sigma)$ such as, $n$-power normal, $n$-power quasi-normal, $k$-quasi-paranormal and quasi-class$A$. Then we show that weighted composition operators can separate these classes.

people usually associate power with military force, multinational corporations, as well as ele-vated political positions. however, marriage and family are not exempted from power strug-gles too; couples often encounter power issues. present article discusses power in families with focussing on power between married partners or conjugal power.the paper also high-lights some of the questions like...

the structure of family organization is recognized upon members’ relationship and their rights and duties. the distinction of paternal, maternal, child and couple roles cause distinction in rights and duties. therefore the rights and duties of roles are bilateral but deferent. two characteristics explain the power division in family: biological abilities and expenditure. man in his marital role...

This essay continues where we left off in [1]: the number of (unordered) partitions of 2−1 as a sum of  powers of 2 is well-understood [2, 3, 4, 5, 6]. What can be said about the number () of (ordered) compositions of 2−1 as a sum of  powers of 2? Clearly (1) = (2) = 1; (3) = 3 since there are three ways to sort {1 1 2} and (4) = 13 since there are twelve ways to sort {1 1 2 4} p...
