We studied the evolution of relativistic electrons in the Fanaroo-Riley Type I (FR I) galaxy 3C449, by observing with the VLA at three frequencies (330, 1445 and 4835 MHz) and in all 4 conngurations for a primary resolution of 3."6. The conventional model for this type of source is that the relativistic electrons are accelerated in the core and subsequently lose energy as the jet ows outward, e...

A series of 18 flume runs were conducted in a 6-m long, 0.5-m wide recirculating flume with a bed gradient of 0.8% to determine the influence of obstruction shape on the formation and characteristics of forced pools. Six differentshaped obstructions were added to the flume with the maximum width of the obstruction held constant at 20 cm, which equaled a 40% constriction of flow. The obstruction...

background: targeting of cd20 antigen with monoclonal antibodies has become the mainstay in the treatment of non-hodgkin's lymphomas and immunotherapeutic depletion of malignant b cells. accessibility of antigen is one of the crucial factors in development of monoclonal antibodies against this antigen. one major problem in expression of full length cd20 is aggregation and misfolding. there...

this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...

The Southern Ocean, a region that will be an ocean acidification hotspot in the near future, is home to a uniquely adapted fauna that includes a diversity of lightly-calcified invertebrates. We exposed the larvae of the echinoid Sterechinus neumayeri to environmental levels of CO(2) in McMurdo Sound (control: 410 µatm, Ω = 1.35) and mildly elevated pCO(2) levels, both near the level of the arag...

Engineering application of advanced computer methods has been developed into product lifecycle management (PLM) which relies upon single but very complex and comprehensive model of product. Recently, generic product models are in the possession of self adaptive capability for the generation their instances considering well defined situations and events. The Laboratory of Intelligent Engineering...

We investigated the impact of frequency and pattern of melatonin signals on reproductive development in Siberian hamsters. Juvenile males gestated in short day lengths and housed in constant illumination to suppress melatonin secretion were infused with melatonin for 5 h either once or twice per day for 20 days. Melatonin infusions at either frequency produced equivalent increases in testes and...

Using dog food as a model of the organic waste, thermophilic composting was carried out for 14 days at a fixed temperature of 60 degrees C. The relationship between organic matter decomposition measured by CO2 evolution during the bio-stabilization process and microbial succession expressed as the changes over time in the restriction fragment length polymorphism (RFLP) patterns of 16S rDNA sequ...

This paper presents an iterative model of knowledge acquisition of gender information associated with word endings in French. Gender knowledge is represented as a set of rules containing exceptions. Our model takes noun-gender pairs as input and constantly maintains a list of rules and exceptions which is both coherent with the input data and minimal with respect to a minimum description length...

We characterize the parameters of the flowing argon plasma produced by a 16-cmdiameter plasma source utilizing a transverse magnetic filter to reduce electron temperature while maintaining the quasineutrality of the flowing plasma, as a function of the operating parameters of the source: discharge voltage, discharge current, and gas flow rate/neutral background pressure. We evaluate the plasma ...
