during the croatian homeland war in 1991, the capacitor batteries of the zadar electric powersubstation (ts 110/35 kv) were damaged, resulting in the severe pollution of the soil with polychlorinatedbiphenyls (pcbs). due to porosity of karstic soil pcbs represent great environmental and human health risksthat need some action. the polluted soil was collected and an experimental field was formed...

the effect of underground cavities in site seismic response was studied over the subway tunnels that are under construction in the city of karaj, using ambient noise measurements as well as numerical modeling. the idea for this research comes from the observation of differences in experimental site transfer function, calculated on more than 100 locations of the city, for the areas near the unde...

introduction: cesarean surgical site infection (ssi) occurs in 3% to 17% of patients who undergo cesarean delivery. ssis increase postcesarean maternal morbidity and health costs and cause longer hospital stays. therefore, we designed a study to assess the effects of normal saline and cefazolin irrigation on the incidence of ssis. methods: in this study, 200 participants were divided into 3 gro...

it was shown that permethrin resistance in adult anopheles stephensi is due to at least three separate mechanisms. cytochrome p-450s and esterases are responsible for two-thirds of the 8-fold enhanced tolerance of the dub-apr resistant strain as compared with a sensitive strain, ind-s. it was postulated that target site insensitivity is also involved. to test this hypothesis, we conducted a neu...

Objective: The aim of this study was to compare the long-term efficacy and safety of combined phacotrabeculectomy (phaco-trab) and trabeculectomy (trab) alone. Methods: Retrospective, non-randomized, interventional case series of phaco-trab and trab. Inclusion criteria were diagnosis of glaucoma for both plus vision impairing coexisting cataracts for phaco-trab. Primary outcome measures were ch...

geographic information systems (gis) are one of the fastest growing computer-based technologies of past two decades, yet, full potential of this technology in construction has not been realized. based upon gis capabilities, construction site layout is one of the areas that gis could be applied. the layout of temporary facilities (tfs) such as warehouses, fabrication shops, maintenance shops, co...

closure of donor site of the flap has special problems. reduction of this site will decrease the morbidity of operation. in this study, we present our experience in donor site size reduction. methods between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. in all patients, coverage of defect was performed with various flaps. substratum horizontal mat-tress sutur...

introduction: direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. we compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (lfp) and lfpspike signals, respectively. methods: signals recorded from mt area of a macaque’s brain was used in a simulation app...
