This experimental study was conducted in a wind tunnel using two turbines in tandem arrangement and downstream turbine is located at X/D=2. The purpose was to investigate how yawing the upstream turbine will affect the performance of the downstream turbine as well as the upstream turbine. Wind loading (thrust force), rotational frequency and power output are the parameters used to define the pe...

of the envenomation maybe both systematic and localized.5 Depending on the species of the snake involved and the amount of venom injected. Localized tissue damage is found to occur in many internal organs including the brain, lungs, heart, kidney, liver and endocrine glands.6,7 On the other hand, cobra venoms were reported to contain many active ingredients that beside neurotoxicity it can Khid...

In a recent paper Sarkar and Maitre (1950) have reported the action of cobra venoin both on the muscle and the neuromuscular junction, the paralysis of the latter setting much earlier and with smaller concentration oi the venom. This is in accordance with the pioneer investigations of Lauder, Brunton and Fayrer (1873, 1874). They have also reported that the conducting power of the nerve remains...

From the implications of the complement system in a large number of diseases, an urgent need for therapeutics effecting reduced complement activity in vivo has emerged. In this study we report the design of a novel class of enzymes of human origin that obliterate functional complement by a noninhibitory, catalytic mechanism. Combining the framework of human C3 and the enzymatic mechanism of cob...

Arisaema speciosum is a wild lily of family Araceae. This paper reports anti-inflammatory properties of the ethanolic extract of the corm of Arisaema speciosum .The ethanolic extract of corm of Arisaema speciosum showed in vitro cytotoxic effect against Ehrlich ascitic cells. When the extract was injected in tumour bearing mice, tumour disappeared in 40% animals. Injection of ethanolic extract ...

Lipide extracts of the red cells of several animal species have been analyzed chromatographically. Genetically determined differences in phospholipide composition were found. Lecithin is absent from the cells of ox, sheep, and goat. Cells containing lecithin are susceptible to the direct hemolysin of cobra venom while cells not containing lecithin are resistant. The facts indicate that the dire...

Phospholipases A, C and D are widely used for studies on the structure of membranes of mitochondria [l-3], erythrocytes [4,5] and microsomes [6]. Information about the arrangement of phospholipids in the membrane can be obtained by elucidating the accessability of certain parts of phospholipid molecules to phospholipase attack. The sensitivity of various respiratory chain segments to cobra veno...

During the past eight years the senior author has been engaged in testing the pharmacological action and therapeutic properties of Indian snake venoms. Chopra and Chowhan (1932 and 1935) showed that the efficacy of the cobra and other snake venoms in relieving the pain of malignant growths and of neuritis and neuralgias was probably due to the presence of such active principles as neurotoxin. The

1. The resistance of erythrocytes of dogs to the hemolytic activity of cobra venom is increased after splenectomy. 2. This increased resistance was observed as early as 4 days after splenectomy and usually persisted for a period of about 3 weeks, when the resistance gradually decreased to normal or slightly beyond. 3. The decrease of resistance to the hemolytic activity of venom for the erythro...

Extracts of the membranes of normal red cells and red cells from all subpopulations of paroxysmal nocturnal (PNH) red cells inhibited antibody-mediated complement activation. These extracts were shown to accelerate decay of the complement complex. C42, and the relative amount of inhibitory activity was similar in normal and PNH membranes. Inhibitors derived from normal red cells markedly decrea...
