Background Outdoor work is associated with high and chronic exposure to solar ultraviolet radiation which might lead an increased risk of developing skin (pre)malignancies. Prevalence actinic keratosis (AK), basal cell carcinoma (BCC), cutaneous squamous (cSCC) melanoma (cM) in Dutch outdoor workers (OW) has not previously been investigated. Objective This study compares the prevalence premalig...

Using the method of homogenization, we present a systematic derivation of the macroscopic equations for air ̄ow and chemical vapor transport in an unsaturated zone with a periodic structure of heterogeneity. The e€ective speci®c discharge and hydrodynamic dispersion coecient are expressible in terms of some cell functions, whose analytical solutions are sought for the simple case of alternate s...

Activated water irrigation has been widely investigated as an effective production increasing measure. However, the response of activated in plant growth and use efficiency (WUE) with amount is not well understood. Here, a pot experiment was conducted to determine effects on winter wheat growth, yield, WUE under amount. Twelve treatments included four types, (i) tap (TW), (ii) magnetization (MW...

it is known that a stochastic dierential equation (sde) induces two probabilisticobjects, namely a diusion process and a stochastic ow. while the diusion process isdetermined by the innitesimal mean and variance given by the coecients of the sde,this is not the case for the stochastic ow induced by the sde. in order to characterize thestochastic ow uniquely the innitesimal covariance give...

fifty-four specimens of the kingsoldier bream, argyrops spinifer (forsskal, 1775) from coastal waters of the persian gulf, in bushehr province, were aged by otolith readings to assess the suitability of using otolith length/weight for age estimation in this fish. otolith length and weight increased along with an increase in length and age of the fish. the relationship between fish length (tl) a...

The effects of swirl and vaporization on droplet dispersion are investigated in the near region of a two-phase, swirling, heated jet. Simulations are based on the numerical solution of time-dependent, axisymmetric gas-phase equations.Droplets’ trajectories are tracked byusingaLagrangianapproach.Forall of the swirl cases investigated, the droplet dispersion exhibits a nonmonotonic behavior, with...

background: aflatoxins (afs) are the most prevalent carcinogenic mycotoxins, produced mainly by aspergillus flavus and a. parasiticus. the general purpose of the present study was to use dehydroacetic acid (dha) and ozonated water (ow) to control a. flavus growth and accumulation of aflatoxin b1 (afb1) in iranian pistachios. methods: three treatment pistachio groups were separately immersed in ...

The effects of viscous dissipation and thermal dispersion due to the presence of ultraŽ ne particles in the lubricating  uid are studied on  ow and heat transfer inside a nonisothermal and incompressible bearing during relief and squeezing stages. The governing equations are nondimensionlized and reduced to simpler forms based on an order-ofmagnitude analysis. Analytical solution for the ener...

We study the dispersion of wind-induced near-inertial oscillations (NIOs) in a fully turbulent baroclinicmesoscale eddy Ž eld characterizedby a continuouswavenumber spectrum. The in uence of the eddy Ž eld on the horizontal dispersion of the differentNIO modes is analyzed using a vertical normal mode expansion. Previous studies have identiŽ ed two dispersion regimes: trapping and strong disper...
