Before the development of egg mediums, serum was used extensively as a medium in the cultivation of tubercle bacilli. Eastwood in 1907 reported that horse, bovine, dog, and pig serums supported good growth of stock cultures of human and bovine tubercle bacilli and also served well as isolation mediums. Since the introduction of egg mediums there has been little use of serum as a medium in itsel...

3 gehaltenen Sonde analysiert. Zusätzlich wirkende Potentiale und die Viskosität des umgebenden Mediums können gemessen werden.

An annual increase of CO2 concentrations in the atmosphere causes global environmental problems, addressed by systematic research to develop effective technologies for capturing and utilizing carbon dioxide. Electrochemical catalytic reduction is one directions conversion into valuable chemicals fuels. The electrochemical at catalytically active electrodes aqueous solutions most studied. Howeve...

The dispersion relations for conventional uniaxial dielectric mediums may be characterized as elliptical or elliptical–like, according to whether the medium is nondissipative or dissipative, respectively. However, under certain constitutive parameter regimes, the dispersion relations may be hyperbolic or hyperbolic–like. We investigate planewave propagation in a hyperbolic/hyperbolic–like uniax...

Communication is an integral part of everyday life. Consumers chat with friends, search for information, and complain to customer service. Salespeople pitch products, employees answer questions, market researchers ask them. But communication doesn’t occur in a vacuum. Modalities (e.g., speaking or writing), channels text, phone call, email), devices smartphone computer) are the mediums through ...

The importance of accurate, reliable recording mediums cannot be understated. Function and esthetics are directly related to this critical step. Dental recording materials must be accurate, easily manipulated, and economical for effective use. Five types of intraoral records of 31 patients were registered and placed on an arcon, semiadjustable articulator to measure the magnitude and direction ...

A light ray, incident at about 5 degrees to the normal, is geometrically plotted through the drawing of the cross section of a soybean leaf using Fresnel's equations and Snell's law. The optical mediums of the leaf considered for ray tracing are air, cell sap, chloroplast, and cell wall. The above ray is also drawn through the same leaf cross section considering cell wall and air as the only op...

I. Overview. The mobile phone (and the smart phone, in particular) is increasingly displacing other mediums as a way to channel content. Given the growth and importance of the telecommunications industry in Africa, and the relentless penetration of smart phone technology, it is therefore unsurprising that Africans are consuming, and creating, an increasing volume of content, of both African and...

Cobalt has great biological effects on human beings and also other living organisms, hence its determination is very important. In this regard, a novel coated graphite electrode was designed for determination of Co2+ ions by exploiting 6-chloro-11- azabenzo[a]phenothiazin-5-one as a neutral ion carrier, for the first time. The foremost function was witnessed from the membrane composition of PVC...
