The present study is intended to develop a Preventive Maintenance (PM) policy for industrial applications, while considering two different objectives: the first objective is to optimize the total maintenance costs, i.e., the Preventive Maintenance (PM) and Emergency Maintenance (EM) Costs Per Unit Time. (CPUT). The second objective is to design the policy in such a way that the simplicity of it...

Indoor air particulate (PM) exposure is several folds more dangerous than  outdoor air  owing to burning of different materials. Burning biomass emits toxic fumes that are found to be associated with  numerous health problems  such as respiratory diseases, etc. In our study area,  approximately 80% of the population of Chhattisgarh state, central India use biomass  such as wood, and cow dung as...

Ambient particulate matter (PM) was sampled in Zabrze (southern Poland) in the heating period of 2009. It was investigated for distribution of its mass and of the masses of its 18 component elements (S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Ge, As, Br, Sr, Cd, Sb, Ba, and Pb) among 13 PM size fractions. In the paper, the distribution modality of and the correlations between the ambient concentrati...

The changes of calretinin (CR)-immunoreactive periglomerular cells in the glomerular layer of the main olfactory bulb (MOB) were investigated in rats differing ages from postnatal month 1 (PM 1) to PM 24. The number of cresyl violet-positive periglomerular cells was similar between PM 1 and PM 12, but they decreased slightly in the PM 24 group. The size of CR-immunoreactive periglomerular cells...

We introduce the pseudo-m-ary (Pm) number system in which numbers are represented by sums of the form ∑ i≥0 ai(m i+1 − 1). We characterize the Pm representations that are produced by the greedy algorithm and show that they form a regular set. In addition, we show that the set of Pm representations that are the sole representations for their corresponding numbers is also a regular set.

The European Corn Borer (ECB), Ostrinia nubilalis (Hübner), is a major corn insect pest. Estimates of damage in the United States due to ECB range between $1-$2 billion per year from yield loss and control costs (Russnogle). A common rule of thumb suggests that one borer per plant can cause a 5% yield loss if the attack occurs during the corn’s critical early development stages (see sidebar). T...

The anti-neoplastic prodrug, cyclophosphamide, requires biotransformation to phosphoramide mustard (PM), which partitions to volatile chloroethylaziridine (CEZ). PM and CEZ are ovotoxicants, however their ovarian biotransformation remains ill-defined. This study investigated PM and CEZ metabolism mechanisms through the utilization of cultured postnatal day 4 (PND4) Fisher 344 (F344) rat ovaries...

The present study, a secondary analysis of published data, assessed (a) the influence of initial positive mood (PM) on smoking cessation and (b) whether smokers low in PM benefited from fluoxetine versus placebo for cessation. Euthymic adult smokers (N = 103) received 10 weeks of cessation treatment. Analyses showed a Time x PM interaction, indicating that higher baseline PM predicted decreased...
