Antibiotic resistance among pathogenic bacteria continues to be a major growing public health problem worldwide. It is well documented that the overuse of antibiotics also leads to new resistant strains, thus decreasing the effectiveness of “front line” antibiotics. Therefore, the detection of the antibiotics to which a bacterium is resistant is critical in designing an effective medical treatm...

induction of systemic resistance to cucumber against marginal leaf blight disease caused by pseudomonas marginalis using silicon application (as 1 &2 mm of sodium silicate) was studied under greenhouse conditions. results indicated that application of 2 mm of sodium silicate remarkably increased resistance in cucumber against the pathogen. according to the results, disease severity in plants tr...

We study the linear resistance at the Kosterlitz–Thouless transition by Monte Carlo simulation of vortex dynamics. Finite size scaling analysis of our data show excellent agreement with scaling properties of the Kosterlitz–Thouless transition. We also compare our results for the linear resistance with experiments. By adjusting the vortex chemical potential to an optimum value, the resistance at...

OBJECTIVES The purpose of this research was to determine the mass concentrations of ions eluted from dental ceramic after an exposure to hydrochloric acid and, drawing on those results, to develop a feedforward backpropagation neural network (NN). MATERIALS AND METHODS Four dental ceramics were selected for this study. The experimental measurement was conducted after 1, 2, 3, 6 and 12 months ...

Oesophageal carcinoma is a common form of cancer in developing countries, especially in the Caspian littoral and northern China. In contrast, it has a much lower incidence in Japan, the U.S.A. and western Europe. Certainly in the case of squamous cell oesophageal carcinoma, dietary composition, smoking, alcohol and exposure to nitrosamines are major risk factors that may partly explain the dise...

Plant phenolics are secondary metabolites that encompass several classes structurally diverse of natural products biogenetically arising from the shikimate-phenylpropanoids-flavonoids pathways. Plants need phenolic compounds for pigmentation, growth, reproduction, resistance to pathogens and for many other functions. Therefore, they represent adaptive characters that have been subjected to natu...

Water vapor condensation is commonly observed in nature and routinely used as an effective means of transferring heat with dropwise condensation on nonwetting surfaces exhibiting heat transfer improvement compared to filmwise condensation on wetting surfaces. However, state-of-the-art techniques to promote dropwise condensation rely on functional hydrophobic coatings that either have challenges...

fusarium head blight (fhb) disease caused by fusarium graminearum is one of the most destructive diseases of wheat that in addition to the loss of product quality and quantity is able to produce the dangerous carcinogenic toxins in human and animals. in this study, the effects of different fertilizer treatments (vermicompost, chemical fertilizer and mycorrhiza) on performance components and exp...

It has been shown that Smad3 exerts both tumor-suppressive and -promoting roles. To evaluate the role of Smad3 in skin carcinogenesis in vivo, we applied a chemical skin carcinogenesis protocol to Smad3 knockout mice (Smad3 / and Smad3 / ) and wild-type littermates (Smad3 / ). Smad3 / mice exhibited reduced papilloma formation in comparison with Smad3 / mice and did not develop any squamous cel...

Heat strain in chemical protective clothing is an important factor in industrial and military practice. Various improvements to the clothing to alleviate strain while maintaining protection have been attempted. More recently, selectively permeable membranes have been introduced to improve protection, but questions are raised regarding their effect on heat strain. In this paper the use of select...
