the purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the ctpa on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, q...

this study was conducted to evaluate the association between aging and regenerative potential of spinal cord injury. three groups of male sprague-dawley rats, including young (40 days), mature (5-6 months) and old (28-29 months) were spinally hemisected at the l1 level. the locomotor performance was assessed weekly for eight weeks after lesion using locomotors' rating scale developed by basso, ...

patients with solitary rectal ulcer syndrome (srus) come to a physician with passage of mucus and bloody liquid within defecation. the treatment for srus is depended to the severity of symptoms and the existance of rectal prolapse. this study is a report of the assessing of rectopexy as surgical modalities for 62 medical treatment resistant srus patients who were referred to the gastrointestina...

introduction:it is well-recognized that collimator-detector response (cdr) is the main image blurring factor in spect.  in this research, we compensated the images for cdr in molecular spect by using stir reconstruction framework. methods: to assess resolution recovery capability of the stir, a phantom containing five point sources along with a micro derenzo phantom were investigated. influence...

monolithic aerogels of high molecular weight polyethylene (mw= 3x106- 6x106 g/mol) have been prepared by solvent extraction with supercritical carbon dioxide from thermoreversible gels prepared in decalin. these low density and highly porous aerogels present an apparent porosity up to 90%. the aerogel morphology observed by scanning electron microscopy (sem) is characterized by spherulitic stru...

medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .it is achievable by shape memory effect. for this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. then shape memory effect was ind...

recovery factor is an important parameter in determining commercial viability of the oil reservoirs. wettability is a major factor that affects oil recovery. therefore, changing rock wettability may enhance oil recovery. in this paper, the effect of polysilicon nanoparticles on wettability change of iranian carbonate reservoir is investigated. to assess this, hydrophilic changes of carbonate ro...

mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. a failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. a number of approaches have bee...

purpose to verify whether active recovery (ar) applied after a kickboxing match resulted in better performance in anaerobic tests when compared to passive recovery (pr). methods eighteen kickboxers volunteered to participate on a kickboxing match preceded and followed by anaerobic tests: squat jump (sj), the counter movement jump (cmj) and the upper-body wingate test. blood lactate (bl), heart ...

results the maximum si was obtained at the highest applied flip angle (45°). the linear relationship between si and nanoparticle concentration was seen up to 112.21 and 98.83 μmol fe/l for the short (10°) and the long (45°) flip angles, respectively (r2 = 0.95). these values were reduced up to 48.54 and 42.73 μmol fe/l for these flip angles with r2 of 0.99. conclusions the maximum si will be in...
