Reduction of fully oxidized Clostridium pasteurianum 8-Feox.,ox. ferredoxin by using pulse-radiolysis techniques yields the half-reduced species 8-Feox.,red. ferredoxin. The subsequent oxidation of 8-Feox.,red. ferredoxin with Co(NH3)5Cl2+ was studied. From a comparison with stopped-flow studies on the 2:1 Co(NH3)5Cl2+ oxidation of 8-Fered.,red. ferredoxin to the 8-Feox.,ox. form it is conclude...

fered a myocardial infarction would be facilitated by better communication between the general practitioner who has the key role, the hospital and the doctor working in industry. Following the symposium, a brief questionnaire completed by participants showed that more than half had changed their practice in direct response to what they had heard. The most frequently cited changes were those rel...

1 A productivity growth rates in Africa have lagged behind the rest of the world due to lack of investment in agriculture in general and in agricultural research and development (R&D) in particular.1,2 Low productivity has especially affected basic African food crops such as sorghum, millet, cassava, sweet potato and cowpea, which are barely traded inter nationally and which benefited very litt...

the saline tannery wastewater also contains the high concentration of organic materials and various chemical compounds like lime, sodium sulfite, sulfate ammonium, sodium chloride, disinfections, vegetable tannins, salts of chromium and chloride. in recent years different applications of advanced oxidation processes (aops) are applied to remove organic loading (cod) from wastewater. advanced ox...

The seventh CCIlT (Consultive Committee of International Telephone and Telegraph), Plenary Assembly has defined ISDN (Integrated Services Digital Network) as a evolution from the existin telephone network that provides end to end digita f connectivity. Wide range of services are antici ated. Both voice and non-voice services will be o /' fered. The network users will have access to these servic...

We present the architecture and practical VLSI implementation of a 4-Tb/s single-stage switch. It is based on a combined input-and crosspoint-queued structure with virtual output queuing at the ingress, which has the scalability of input -buffered switches and the performance of output-buf-fered switches. Our system handles the large fabric-internal transmission latency that results from packag...
