the present study examined the effect of packaging film on the quantitative and qualitative properties of button mushrooms. the three types of packaging tested were a clear polyvinyl chloride box, polyvinyl chloride stretch film and biaxially-oriented polypropylene film (bopp). the five types of moisture absorbers examined were silica gel (2.5 g, 1.25 g), sodium chloride (2.5 g, 1.25 g), and si...
over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (tfc) membranes. in advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (tfn) membranes. however, in the last generation of tfns, an ultrathin selective film of nanoparticles is coated...
If a tangle, K ⊂ B, has no planar, meridional, essential surfaces in its exterior then thin position for K has no thin levels.
OBJECTIVE To find out what proportion of Plasmodium falciparum infections are treated in rural Gambia. METHODS Subjects from four villages in the Gambia were followed over nine months through visits to village health workers. Monthly cross-sectional malaria surveys measured the prevalence of P. falciparum infection. Linked databases were searched for treatment requests. Treated cases were ind...
In the interwar period VD prevention films accompanied the introduction of new "permanent" treatments for syphilis. While they still warned the audience about the dangers of infection, these films were primarily designed to inform about these new methods for curing syphilis. These methods could only be effective if the infected patient immediately consulted a certified doctor (as opposed to a c...
Introduction: Regular using of the toothbrush, mouthwash and dental floss is useful in prevention and treatment of the oral diseases. Aims: This paper examines the impact of an educational film on the promotion of the student’s oral health behavior. Methods and Material: This research was conducted in Chabahar in 2011-2012, on 10-12 year old girls .Three hundred students were randomly assigned ...
Background: Self-medication is a serious health problem. The aim of this study is determining the effect of education based on health belief model on improving the preventive behaviors of self-medication in women under the supervision of health institutions of zone 3 of Tehran. Methods: This quasi-experimental case-control survey was carried out on 88 women. Sampling method was clust...
– gafchromic xrct radiochromic film is a self developing high sensitivity radiochromic filmproduct which can be used for assessment of delivered radiation doses which could match applications suchas computed tomography (ct) dosimetry. the dose response of gafchromic xrct radiochromic film hasbeen measured with reflectance spectrophotometry and desktop scanners. the film automatically changescol...
in this research, tellurium (te) film with thicknesses of 100-250 nm were deposited on ceramic substrates by thermal evaporation at 373 k. the thickness of the film was determined by rutherford backscattering spectroscopy. the influence of the thickness on the structural, morphological and molecular bonds was characterized using xrd, scanning electron microscope, and raman spectroscopy. the xrd...
A desired reflectance profile versus frequency (wavenumber) can be directly Fourier transformed into the index of refraction profile as a function of thickness which would produce the desired spectral reflectance profile. This tool has existed for some years now but does not seem to be in common use. This paper lays out some of the principles to aid in making the process more understandable, in...
