contamination of soil and air due to hydrocarbon is a global issue and bioremediation providesprobably the best way to remediate the contaminants. the current study shows the biodegradation of crudeoil, diesel and used engine oil by a newly isolated bacillus cereus strain drdu1 from an automobile engine.hydrocarbon degrading strains were screened on bh (bushnell and haas broth) agar supplemente...

the tumors in which odontogenic differentiation is fully expressed are the odontomas. odontomas are considered as hamartomas rather than a true neoplasm. these tumors are composed of enamel, dentine, cementum and pulp tissue. it is most commonly associated with the eruption of the teeth. they are usually discovered on routine radiographic examination. in exceptional cases, the odontoma erupts i...

colletotrichum species are associated with citrus plants as pathogens, saprobes and endophytes. according to the most recent multigene phylogenetic analysis, a lot of changes were happened in the taxonomy and species delimitation in the genus colletotrichum. in this investigation, 292 colletotrichum isolates were obtained from leaves, fruits and stems of citrus species at golestan, mazandaran, ...

candidiasis , the main opportunistic fungal infection has been increased over the past decades. this study aimed to characterize c.albicans species complex ( c.albicans , c.dubliniensis , and c.africana ) isolated from patients with respiratory infections by molecular tools and in vitro antifungal susceptibilities by using broth microdilution method according to clsi m27-a3 guidelines. totally,...

diosmin, a vascular-protecting agent, is practically insoluble in water, and its oral absorption is limited by its extremely low dissolution rate. in this study, β-cyclodextrin (βcd) and 2-hydroxypropyl-β-cyclodextrin (hpβcd) were obtained to improve the solubility and dissolution rate of diosmin. phase solubility studies of diosmin with βcd and hpβcd in distilled water were conducted to charac...

we investigate buchbaum and eisenbud's construction of the second symmetric power $s_r(x)$ of a chain complex $x$ of modules over a commutative ring $r$. we state and prove a number of results from the folklore of the subject for which we know of no good direct references. we also provide several explicit computations and examples. we use this construction to prove the following ...
