Heat assisted magnetic recording HAMR is a potential solution to extend the limits of conventional magnetic recording. In HAMR, the heating of the recording medium is achieved with a near-field optical transducer. Although the literature suggests novel transducers, there is little consideration of the optical and thermal aspects of the magnetic medium. In this letter we suggest a recording medi...

abstract background: the aim of this study was to compare the efficiency of conventional slow sand filter with modified filter bed with crushed recycled glass in removing of turbidity and total and fecal coliforms from water resources.   methods: in this study efficiency of conventional slow sand filter and modified filter bed with crushed recycled glass during 4 months was compared and their p...

AIMS To test the bactericidal activity of standard organ culture medium, and to compare the sensitivity and rapidity of blood culture bottles with conventional microbiological methods for detection of bacteria and fungi inoculated in a standard cornea organ culture medium. METHODS The bactericidal activity of contaminated standard organ culture medium containing 100 IU/ml penicillin, 0.1 mg/m...

In this study; iron based powder metal (PM) bushing compacts were sintered via medium frequency induction heating system. Iron based powders were mixed with 2 wt.% copper (Cu), 0.3 wt.% carbon (C) and 1 wt.% zinc stearat (Zn-st) via V-Type mixer. PM compacts were sintered by 2 different sintering processes. One of them was conventional sintering method other was medium frequency induction sinte...

background and objectives: diagnosis of avian tuberculosis by conventional culture method is still considered as the “gold standard” technique. the main objective of this study was to compare growth of mycobacterium avium subsp. avium on four specific mycobacterial cultures such as glycerinated lowenstein-jensen medium, pyruvate-enriched lowenstein- jensen medium, mycobactin j-supplemented herr...

PURPOSE To establish a culture technique for human corneal epithelial equivalents that do not require fetal bovine serum (FBS), feeder cells, or bovine pituitary extracts and compare this system with conventional culture medium with FBS and mouse 3T3 fibroblasts. METHODS Human corneal limbal tissue from donor corneas was dissociated on denuded amniotic membranes and then cultured for 3 weeks ...

various techniques and culture media were developed for rapid identification of salmonella serovars. however, there are still problems with their sensitivity and specificity. in an attempt to reduce the time spent to obtain a result and to minimize the problems associated with rapid detection systems such as interference from food ingredients debris, micro flora in feces, and lack of sensitivit...
