The North Sea has warmed in recent years and there is an ongoing debate into how this is affecting the distribution of fishes and other marine organisms. Of particular interest is the commercially important Atlantic cod (Gadus morhua L.), which has declined sharply in abundance in the North Sea over the past 20 years. Observations of the temperature experienced by 129 individual cod throughout ...

OBJECTIVE To determine the frequency of various types of improper cause-of-death (COD) statements reported on death certificates and whether the frequency differed by specialty of the certifying physician. DESIGN Cross-sectional descriptive study. SETTING 2 medical centres in Tainan, Taiwan. PARTICIPANTS A total of 2520 death certificates issued by 230 physicians. MAIN OUTCOME MEASURES ...

ÐThe need for readily biodegradable organic matter to support denitri®cation and enhanced biological phosphorus removal (EBPR) can be satis®ed using external or internal carbon sources. This paper examines the production and removal of volatile fatty acids (VFAs), mainly acetic acid, and other hydrolyzed products from sludge using hydrothermal treatment at subcritical (<3748C) and supercritical...

This paper examines the use of chemical or electrocoagulation treatment process followed by ion-exchange process of the textile dye effluent. The dye effluent was treated using polymeric coagulant (cationic dye-fixing agent) or electrocoagulation (iron and aluminum electrode) process under various conditions such as various current densities and effect of pH. Efficiencies of COD reduction, colo...

As a first step of treatment of landfill leachates (total COD – 1,430-3,810 mg/l, total nitrogen 90162 mg/l), a performance of laboratory UASB reactors has been investigated under mesophilic (30 C), sub-mesophilic (20 C) and psychrophilic (10 C) conditions. Under hydraulic retention times (HRT) of around 7 h, when the average organic loading rates (OLR) were around 5 g COD/l/day, the total COD ...

Reported herein is the synthesis of the previously unknown [Ir(1,5-COD)(μ-H)](4) (where 1,5-COD = 1,5-cyclooctadiene), from commercially available [Ir(1,5-COD)Cl](2) and LiBEt(3)H in the presence of excess 1,5-COD in 78% initial, and 55% recrystallized, yield plus its unequivocal characterization via single-crystal X-ray diffraction (XRD), X-ray absorption fine structure (XAFS) spectroscopy, el...

Treatment of starch wastewater was investigated in a 30 l capacity pilot scale anaerobic baffled reactor (ABR) under mesophillic conditions. The reactor was operated at different hydraulic retention times (HRTs) of 72; 48 and 24 h. Corresponding organic loading rates (OLRs) were 8.7; 7.6 and 22 kg COD/m 3 . d. The results showed that COD and BOD5 removals exceeded 40 and 50% respectively at OLR...

در این طرح با ایده ای کاملا نوین، با اختلاط محلول نمک نیترات فلزات نیکل و پالادیم با سل در حال تراکم پایه کاتالیست (آلومینیوم هیدروکسید)، که خود با پیش سازهای مختلف سنتز شده است، بافت نهایی دو نمونه کاتالیستni-pd/al2o3 تهیه می گردد. بدین ترتیب که در یک مورد، قطره قطره آمونیاک غلیظ به محلول آبی نیترات آلومینیوم اضافه شده ورسوب هیدروکسید آلومینیوم با10ph = حاصل می شود، سپس محلول آبی نیترات نیکل و...

Recent observations of cod movement across stock boundaries are generally consistent with historical tagging data as well as information from other stock identification approaches. This working paper provides a historical context in which to consider recent tagging data for spatial delineation of cod stock assessments (TOR C). Introduction The objective of this report is to review the literatur...
