Buckle folds are common traps for hydrocarbon in several contractional provinces. Buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. An important parameter affecting buckle folding of a competent zone above a mobile decol...

Bovine genital campylobacteriosis (BGC), caused by Campylobacter fetus subsp. venerealis, is associated with production losses in cattle worldwide. This study aimed to develop a reliable BGC guinea pig model to facilitate future studies of pathogenicity, abortion mechanisms and vaccine efficacy. Seven groups of five pregnant guinea pigs (1 control per group) were inoculated with one of three st...

purpose: to evaluate the anatomical and functional outcomes of surgical management of retinal detachments associated with choroidal colobomas methods: in this retrospective study, 31 eyes of 31 patients with coloboma-related retinal detachments enrolled. all the eyes underwent standard three-port pars plana vitrectomy with internal tamponade with nonheavy silicon oil in 24 (77.4%) or 20% sulfur...

purpose: to compare the anatomical results of scleral buckling surgery with and without retinopexy in the management of phakic rhegmatogenous retinal detachment (rd). methods: in this retrospective, nonrandomized, interventional, comparative case series, data of 71 phakic eyes of 71 patients with rhegmatogenous rd that had undergone scleral buckling were evaluated. the procedure in 41 consecuti...

the purpose of this study was to compare the anatomic and visual outcome of primary vitrectomy with scleral buckling in patients with retinal detachment following cataract surgery. fifty-six consecutive patients with retinal detachment after cataract surgery were randomly assigned to two treatment groups: standard scleral buckling and standard three-port deep vitrectomy. successful treatment wa...

Spirochetes are associated with destructive periodontal diseases, and one cultivatable oral species, Treponema denticola, binds to mammalian cells and perturbs metabolism. To evaluate the cytoskeletal responses and attachment functions of human gingival fibroblasts (HGF) exposed to T. denticola, monolayers of HGF were incubated with T. denticola strains ATCC 35405, e, and e' in serum-free mediu...

the aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting esfahan's edible fig (ficus carica cv. sabz). a hand held limb shaker with adjustable shaking frequency and amplitude was used for this study. a 3x3 factorial experiment with three levels of oscillating frequency (10, 12 and 14 hz) and three levels of shaking amplitude (20, 32.5 and 45 ...

Marine particles in the ocean are exposed to diverse bacterial communities, and colonization and growth of attached bacteria are important processes in the degradation and transformation of the particles. In an earlier study, we showed that the initial colonization of model particles by individual bacterial strains isolated from marine aggregates was a function of attachment and detachment. In ...

The dispersal phase that completes the biofilm lifecycle is of particular interest for its potential to remove recalcitrant, antimicrobial tolerant biofilm infections. Here we found that temperature is a cue for biofilm dispersal and a rise by 5 °C or more can induce the detachment of Pseudomonas aeruginosa biofilms. Temperature upshifts were found to decrease biofilm biomass and increase the n...
