One of the basic mechanisms of photo-bio-modulation is the acceleration of electron transfer by electromagnetic radiation in the visible and near infra-red region of the spectrum [1,2]. In the presence of an electron acceptor such as molecular oxygen (O2), electron transfer reduces O2 to the super-oxide anion O2 , which subsequently dismutates into hydrogen peroxide (H2O2) [3]. Both O2 and H2O2...

Sow production indicators, including litter size, litter weight, and the length of time that sows remained in the herd (sow longevity), were used to characterize sow performance and profitability. Sow longevity and production records from 148,568 sows in 32 commercial herds from Central Illinois from January 1995 to May 2001 were analyzed using survival and repeatability models, respectively. T...

The possibility of a new technique for fabricating nanoparticles from thin films using selective oxidation in an atmosphere mixture of water vapor and hydrogen was investigated. Fe-5wt.%Al films were RF-sputtered and annealed in the atmosphere mixture at 900°C for up to 200 min, in order to oxidize aluminum selectively. Thermodynamics simulation showed that temperatures exceeding 800°C are nece...

The present study investigated the effects of back-fat thickness at d 107 of gestation and housing types during gestation on reproductive performance and behavior of sows. A total of 64 crossbred sows (Landrace×Yorkshire) in their 3 to 4 parities were allotted to one of four treatments (n = 16) over two consecutive parities. During each parity, sows were assigned to two gestational housing type...

one fundamental strategy for increasing efficiency of plans which aim to develop natural resources is decreasing water loss and using this restricted water optimally. in arid and semi-arid regions such as a large part of iran, increasing period of irrigation which results in decreasing the irrigation costs, without causing water stress to planted sapling is a vital task. in this research we exa...

BACKGROUND Superoxidized water (SOW) is known to be a potent disinfectant. The aim of this study was to evaluate the toxicity and complications on the peritoneal surface and liver after infusion of pH-neutral SOW into the peritoneal cavity of rats. MATERIAL AND METHODS Thirty Wistar-Albino rats weighing 250-300 g were randomly divided into 3 groups (10 rats/group). Group1 (control group) rats r...

reactive powder concrete (rpc) is an ultra high performance concrete which has superior mechanical and physical properties. the rpc is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (w/b) (less than 0.20) and super plasticizer (sp). the rpc has a very high compressive and tensile strength with better durability prope...

Both the oxidized and reduced forms of Hipip (high-potential iron--sulphur protein) are reduced (approx. 30% yields) by eaq.- in a single-stage process, rate constants 1.7 x 10(10) and 1.8 x 10(10) M-1 . s-1 respectively, at 25 degrees C, pH 7.0 (5 mM-phosphate). Super-reduced Hipip, which is formed in the latter case, has a spectrum which closely resembles that of reduced ferredoxin, i.e. Fe4S...
