Unfertilized eggs of the marine worm Nereis limbata subjected to electrical currents (direct or alternating) undergo remarkable changes. Certain minute granules just inside the surface of the egg absorb water and swell to more than 300 times their original size and thereby produce a mass of jelly which surrounds the egg with a zone about as wide as the original diameter of the egg. The amount o...

In order to expand the possibilities of designing technological processes for finishing shut-off valve parts, in some cases it is advisable use varying various influences a single combined method with imposition an electromagnetic field. A reasonable combination physical allows us provide necessary design parameters, sufficient productivity and increase resource finished products.

Guanidine does not inhibit the translation of viral RNA into virus specific proteins but it seems to prevent the generation of functional viral polymerase from precursor material. In the presence of guanidine, "inhibitory protein (s) " responsible for the shut-off of cellular protein synthesis are still produced provided that the multiplicities of infection are high. The incoming (parental) vir...

etc., were removed from the cavity. These bones were macerated and no fleshy part of the foetus was found. The cavity was entirely shut off from the general abdominal cavity. Coils of intestines could be seen behind separated by a very thin membrane. The Assistant Surgeon examined the patient per vaginam at the time of operation and found the uterus not enlarged and entirely separate from the c...

Willem Bilderdijk (1756–1831), Dutch writer and poet, son of an Amsterdam physician. When he was 6 years old he was struck by an accident to a foot, causing inflammation of the periosteum. Medical errors caused him to stay inside, shut off from the outside world and his peers. He devoted his childhood and youth to study, drawing and writing. He became a historian, linguist, poet and lawyer. Sou...

We derive the distribution of the time-to-empty for an open tandem Jackson network assuming that, while in equilibrium at time 0, the arrival stream is suddenly shut off. The analysis is based on analogous results regarding the distribution of the time-to-empty for the corresponding closed tandem Jackson network. The results obtained are used in the analysis of a two-class tandem Jackson networ...

Two types of neurons are involved in the regulation of rapid eye movement (REM) sleep, the REM-ON and the REM-OFF neurons. As the name suggests, the REM-OFF neurons cease firing during REM sleep and they are norepinephrinergic. It has been shown that cessation of these neurons is a pre-requisite for the generation of REM sleep and GABA shuts them off. Further, if these neurons do not shut off, ...

We determined the microbicidal activities of antibacterials against nonreplicating Mycobacterium smegmatis grown in a starvation-based Loebel model for persistence. Whereas most drugs lost their activity, fluoroquinolones retained lethal potency. Dose-response characterizations showed a paradoxical more-drug-kills-less Eagle effect. Pretreatment of cultures with chloramphenicol blocked the leth...

One highly undesirable characteristic of mature assets that inhibits oil recovery is high water production. Polymer gel treatment a popular conformance improvement technique applied in this regard due to its cost effectiveness and proved efficiency. Despite popularity, optimum performance polymer hydrogels shut off inhibited by excessive aggregation, difficulty controlling gelation, their insta...
