six hundred 1-d-old male broilers (ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. from d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. mortalities were inspected to determine the cause of death and diagnose of ...

T HE prothrombic activity of plasma, as measured by the one-stage method, decreases as plasma ages (x-3) because of deterioration of ‘labile factor’ necessary for the rapid conversion of prothrombin to thrombin by thromboplastin plus calcium. When, however, determinations are made by a modified procedure in which the test plasma is first diluted with pdkombin-free fresh plasma, the aged plasma ...

1. A specific method is described for the measurement of angiotensin I converting enzyme activity in plasma with 125 I-labelled angiotensin I used as substrate. 2. Converting enzyme activity in plasma from fifteen normal subjects, eleven patients with sarcoidosis, twelve patients with chronic obstructive pulmonary disease and three patients with shock lung was assayed by this technique. 3. Pati...

A microwave-induced, steam/Ar/O2, plasma "torch" was operated at atmospheric pressure to determine the feasibility of destroying volatile organic compounds (VOCs) of concern. The plasma process can be coupled with adsorbent technology by providing steam as the fluid carrier for desorbing the VOCs from an adsorbent. Hence, N2 can be excluded by using a relatively inexpensive carrier gas, and the...

In a low-temperature plasma, the electrons pick up energy from electric field in collisions with atoms and molecules, gaining high kinetic that must be sufficient for ionizing reactions to sustain plasma. For molecular gases, an average per heavy gas particle is thus available specific input, yielding plasma activation by inelastic collisions. Following distribution law, probability mechanism c...

A twin surface dielectric barrier discharge is used for the catalyst-enhanced plasma oxidation of 300 ppm n-butane in synthetic air. Plasma-only operation results conversion into CO and CO2. Conversion improved by increasing temperature feed gas, but selectivity shifts to undesired CO. ?-MnO2 as a catalyst deposited on electrodes spray coating with distance 1.5 mm between uncoated grid lines sq...

Plasma-catalytic ammonia decomposition as a method for producing hydrogen was studied in packed-bed dielectric barrier discharge (DBD) reactor at ambient pressure and fixed plasma power. The influence of packing the zone with various materials, typically used catalyst supports, examined. At conditions (21 W, 75 Nml/min NH 3 ) where an conversion 5% achieved alone, improved found when introducin...
