Within the framework of the SLAC/CERN studies of 30 GHz linear colliders, an attempt has been made to scale as closely as possible the existing X-band NLC damped detuned accelerating structure to 30 GHz. A simple scaling was not possible because of mechanical and RF constraints. The 30 GHz design has 101 cells and a minimum aperture of 3.4 mm. In order to obtain acceptably small values for both...

The screening properties of fullerene molecules are described by means of a continuum model which uses the electronic wavefunctions of planar graphite as a starting point. The long distance behavior of the system gives rise to a renormalizable theory, which flows towards a non trivial fixed point. Its existence implies an anomalous dielectric constant. The screening properties are neither metal...

Animalsand Treatments. Male albinoDonryurats, weighing 100 to 120 g (supplied by Kitayama Rabes Corp., Kyoto, Japan), were given laboratory chow and water ad !ibitum and were adapted to constant laboratory conditions (17, 18). Rats weighing 190 to 220 g were used for experiments. When specified, the rats were adrenalectomized 7 days before 70% hepatectomy. At the beginning of the experiment, th...

Previous studies have demonstrated that electrically induced seizures in rat result in an increased brain intracellular sodium which can be decreased by treatment with sodium diphenylhydantoin (DPH). The correlation of cation transport with membrane-oriented sodium-potassium-adenosine triphosphatase (Na-K-ATPase) prompted an investigation of the effect of DPH upon ATPase enzyme activity.Rat cer...

onion (allium cepa) bulb from liliaceae has antioxidant, spasmolytic and antihypertensive activities. the aim of present study was to investigate the antispasmodic effect of onion peel on rat ileum contractility. onion peel powder was extracted by maceration in 70% alcohol for 72 h. a terminal portion of ileum from male wistar rat was dissected and its contractions were recorded isotonically in...

were studied in the forward and reverse directions. As expected from the separate reactions, the apparent equilibrium constant for the combined reactions (KC + C) is dependent on both Z and free [M&+1 and can vary from 180 X 10m7 at Z = 0.1, free [M&‘] = 5 pM to 3000 X lo-’ at Z = 0.4, free [M$’ l] = 1.4 mM. At the cellular free [Mti’], 1 mu, Z = 0.25, and 38”C, KC+C for the combined reactions ...

The effects of mefloquine on the mechanical activity of the mouse isolated rectal smooth muscle was studied. Mefloquine (4.1 x 10(-5) - 5.2 x 10(-3)M) when applied alone and separately exerted variable effects on the rectum. In some preparations, it caused slight phasic contractions while in others no response was elicited. When the external Ca(2+) was increased from 1.8 mM to 300 mM mefloquine...
