Both eyes of rabbits whose right eyes had previously been injected with Neisseria meningitidis were injected with Diplococcus pneumoniae. The pneumococci failed to grow in the right eye of most rabbits challenged 2 and 4 days after the injection of the meningococci, but grew well in all left eyes. The "protective" effect was less pronounced in the rabbits challenged on days 6 and 9 and virtuall...

A method, which utilizes the large difference in ionization potentials between successive ionization states of trace atoms, for injecting electrons into a laser-driven wakefield is presented. Here a mixture of helium and trace amounts of nitrogen gas was used. Electrons from the K shell of nitrogen were tunnel ionized near the peak of the laser pulse and were injected into and trapped by the wa...

Established autochthonous sarcomas induced in the hind limbs of mice by 3-methylcholanthrene were treated with our method of "regional blood flow-interrupting hyperthermic chemotherapy." After administration of an injection of 20% of the dose of carbazilquinone (CQ) lethal for 50% of the animals (1 mg/kg i.V.), followed by temporary interruption of blood flow of the tumor-bearing limbs and warm...

Production from unconventional oil reservoirs has always been a critical issue for the industry. In this regard, we implemented set of experimental scenarios containing CO 2 /N cyclic injection, foams generated by nitrogen and carbon dioxide, dioxide combined effect surfactant enhanced recovery methods. As water injection reached plateau around two pore volume continued tests different scenario...

It has been shown by a number of observers that the administration of iodides both to dogs and to human beings causes an increase in the output of nitrogen in the urine. One of the earliest observers (1) working with dogs showed that this was in part at the expense of the nitrogen excreted in the feces, but that the total amount of nitrogen excreted was none the less increased. We have been abl...

Background and aim: Warts are the most common clinical presentation of human papilloma virus infection of human skin and mucosa. They are more common on hand, foot, face and genital area. They are benign skin colour lesions with different clinical forms. There is no specific treatment for them. In this trial the therapeutic effect of intralesional injection of bleomycin and cryotherapy on...

oxides of nitrogen are the major emission from a diesel engine. it is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of no is promoted. various techniques are therefore employed to reduce the nox emission like egr, scr, etc. in this present work a rotating injector is a tec...

A dedicated test of the effects of Nitrogen contamination in liquid Argon has been performed at the INFN-Gran Sasso Laboratory (LNGS, Italy) within the WArP R&D program. A detector has been designed and assembled for this specific task and connected to a system for the injection of controlled amounts of gaseous Nitrogen into the liquid Argon. Purpose of the test is to detect the reduction of th...

With the increase of fire in high-rise buildings recent years, demand for high-performance Water Tower Fire Truck (WTFT) is increasing day by day. In order to improve injection capacity ultrafine dry powder WTFT, this article adopts way adding blow-assisted pipe realize nitrogen-assisted blowing, and internal flow field existing was analyzed optimized CFD simulation. The influence law size para...
