This abstract presents a laboratory study of a coagulation/flocculation process on an urban snow melt mixture. Coagulation/flocculation is ubiquitous in water treatment, but has seen little use in the stormwater context. Using a jar-test procedure five different chemicals are evaluated as primary coagulants and their treatment performance on urban snow melt with respect to solids removal and me...

The Jewish Autonomous Region (JAR) of Birobidzhan in Siberia is still alive. once famous “Siberian Zion”, at the confluence Bira and Bidzhan rivers, a stone’s throw away from China day Pacific Ocean, 9,000 km six days by train Moscow, geographical reality. political class Soviet Union decided to create territory size Belgium for settlement Jews, choosing region on border between Union. It belie...

Technical limitations restrict routine anaerobe isolation from clinical materials in resource-limited laboratories. An innovative two steps combustion candle jar technique may be suitable for such setup. This system was tried with one case of chronic osteomyelitis developed on supracondyler compound fracture. Porphyromonas spp. was isolated and identified. Vancomycin was recommended based on in...

7or-(4'-Amino)phenylthio-l,4-androstadiene-3,17-dione(7a-APTADD), a potent enzyme-activated irreversible inhibitor, was examined in two different human cell culture lines, MCF-7 human mammary carcinoma cells and JAr choriocarcinoma cells. Both the MCF-7 and JAr cell culture systems exhibit aromatase activity, and 7a-APTADD was evaluated for its aromatase-inhibitory activity, for its ability to ...

BACKGROUND Topical erythromycin/benzoyl peroxide (EBP), marketed for acne treatment, must be compounded by a pharmacist and requires subsequent refrigeration, warranting the development of alternate formulations. OBJECTIVE This trial compared the efficacy and tolerability of a single-use EBP combination package (EBP Pak) with those of its matching vehicle control (VC Pak) and the original, re...

BACKGROUND Bioflocculants effect the aggregation of suspended solutes in solutions thus, a viable alternative to inorganic poly-ionic and synthetic organic flocculants which are associated with deleterious health problems. Consequently, a consortium of two bacteria species were evaluated for optimized bioflocculant yield following the inadequacies of axenic cultures. RESULTS 16S rDNA nucleoti...

The gymnotiform fish Eigenmannia generates weakly electric signals for electrolocation and communication. The signals are produced by electric organ discharges (EODs) that are driven by a medullary pacemaker nucleus. To avoid jamming by neighboring conspecifics with similar frequencies, a fish raises its own EOD frequency if the neighbor's frequency is lower, and it lowers its EOD frequency if ...
