abstract heavy metals uptake and their distribution in plants are different. in addition to the genetic factors, environmental factors such as interactions of heavy metals with essential elements are very important on the amount of heavy metals uptake. in this study, the effects of iron and manganese on accumulation of cadmium in shoot and root of sunflower and corn in different concentration o...

BACKGROUND In 1992, Congress enacted the Synar Amendment, requiring states and territories to enact a law prohibiting the sale of tobacco to minors and to enforce that law in a manner that could reasonably be expected to decrease the availability of tobacco to minors. The Department of Health and Human Services (DHHS) was mandated to withhold block grant funding from noncompliant states. OBJE...

Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...

abstract background & aim: food insecurity is defined as limited availability at all times to sufficient food of an active life. the aim of this study was assessing the food insecurity status and some associated socioeconomic factors in women with metabolic syndrome. methods: the present cross-sectional study was conducted on 130 women between 30-60 years of age with metabolic syndrome referred...

service availability is important for any organization. this has become more important with the increase of dos attacks. it is therefore essential to assess the threat on service availability. we have proposed a new model for threat assessment on service availability with a data fusion approach. we have selected three more important criteria for evaluating the threat on service availability and...

Discounting is a causal-reasoning phenomenon in which increasing confidence in the likelihood of a particular cause decreases confidence in the likelihood of all other causes. This article provides evidence that individuals apply discounting principles to making causal attributions about internal cognitive states. In particular, the three studies reported show that individuals will fail to use ...

Electronic effects were investigated on the singlet–triplet energy gaps of divalent unsaturated seven- membered ring R2C6H6M (M=C, Si, Ge, Sn, Pb, R= –H, -CH3, i-Pr , t-Bu) at B3LYP/6-311++G** level. All the triplet states of R2C6H6C were more stable than the related the singlet states while all the singlet states of R2C6H6M (M= Si, Ge, Sn, Pb, R= –H, -CH3, i-Pr , t-Bu) were more stable than th...
