Total adenylate kinase activity was determined in developing rat liver. The activity was 18 units/g wet weight of tissue in foetal liver; this increased to 41 units/g immediately after birth and continued increasing until adult activities of 150 units/g were reached after two weeks. The adenylate kinase activity was separated into four isoenzymes. Only isoenzymes II and III were observed in foe...

Using some new processing of the multichannel sonic (MCS) log data from Site 418A, the resulting P, S, and Stoneley wave velocity estimates and apparent attenuation were integrated with the natural gamma, spectral gamma, resistivity, neutron, density, and caliper logs and core lithology information for interpretation of lithologic cycles and possible paleo fluid flow intervals. These data indic...

introduction: increasing costs of health and treatment services has led health economics specialists and even physicians in all countries to seek new methods for controlling and reducing costs in medical and health services. the present study was aimed to estimate the costs of a cardiac care unit (ccu) in a governmental hospital in iran. methods: in order to determine the end cost, a stepwise p...

Consider a simple network flow problem in which there are n channels directed from a source to a sink. The channel capacities are unknown and we wish to determine a feasible network flow of value D. Flow problems with unknown capacities arise naturally in numerous applications, including inter-domain traffic routing in the Internet, bandwidth allocation for sending files in peer-to-peer network...

Tactical communication network environment is different to the civil mobile adhoc network. It is of special connectivity, traffic flow characteristic and mobility. Its traffic flow model is the foundation for adhoc network designing, planning, controlling and managing. Each characteristic can be depicted correctly only when the model is accuracy. This thesis studied the traffic flow characteris...

This paper presents a Particle Swarm Optimization (PSO) based algorithm for Optimal Power Flow (OPF) in Combined Economic Emission Dispatch (CEED) environment of thermal units while satisfying the constraints such as generator capacity limits, power balance and line flow limits. Particle Swarm Optimization is a population based stochastic optimization, developed by Kennedy and Eberhart [12], in...

Continuous flow is one of the main focuses of scheduling repetitive projects. Construction practitioners and researchers have proposed approaches to maintain continuous flows. However, many of these approaches only consider deterministic activity durations or have some other methodological limitations. Accordingly, a continuous flow simulation model is presented in this paper in order to overco...
