Abstract:

The dissociative ionization by electron impact of H₂, H₂O, and H₂S was investigated between the electron impact energies of 20 and 45 eV. Protons were the detected fragments, and a time-of-flight method was used to measure the proton kinetic energies. By also measuring the thresholds for the production of discrete energy groups of protons, it was possible to determine the dissociation limits and kinetic energy distributions for individual electronic states. It was found that autoionizing states that lead to dissociation were the major contributors of proton fragments for all of the molecules i

Abstract:

A coincidence has been observed between H(2S) and H⁺ fragments resulting from the bombardment of H₂ with 100 eV electrons. A significant source of this coincidence is believed to be the 2sσ(g) state of H₂⁺. The time-of-flight (TOF) distribution of H(2S) fragments from the 2sσ(g) state was measured and converted to the kinetic energy distribution from which the potential energy of the 2sσ(g) state in the Franck-Condon region was constructed. The result is in good agreement with a published calculation.

Abstract:

Two identical instruments have been developed for use in the field to make radiometric measurements. They have been described as spectropolarimeters because of their ability to make polarization measurements in narrow spectral passbands. They have been used as part of a NASA sponsored project to monitor the spectral and temporal response of the thematic mapper satellites. These satellites allow many natural and man-tended resources to be monitored over years of time, thus allowing their use to be planned for in the future.

Abstract:

The La Crosse (LAC) virus is a member of the California encephalitis group of bunyaviridae (Porterfield et al., 1975 and 1976). It is one of an envelope virus and this virus under acidic conditions (below pH 6.3) has been demonstrated to result in cell-to-cell fusion (Gonzalez-Scarano, 1984). The LAC virus is also capable of forming virus-to-virus fusion particles. The focus of this thesis is the analysis of the structure and function of this virus-to-virus fusion by cryo-electron microscopy at different pH and temperatures. The results of this study provide the basis for further study of the

Abstract:

Nitrification is a central part of the nitrogen cycle, whereby the most reduced form, ammonia, is converted to the most oxidised form, nitrate via nitrite. The first step is performed by ammonia oxidising bacteria (AOB) and archaea (AOA), with the second step performed by nitrite oxidising bacteria (NOB). Although both groups are closely associated in nature, ammonia oxidisers have received more attention compared to NOB as ammonia oxidation is considered the rate-limiting step. Nitrobacter and Nitrospira are two important groups of soil NOB. To determine whether there are specific association

Abstract:

The adsorption of zinc ions as a function of pH and total dissolved metal concentration was experimentally investigated for three types of clays (kaolinite. montmonllonite. and Londonderry). The results indicate increases in adsorption of the zinc ions occurs with increases in pH for each of the three clays. Langmuir and Freundlich isotherms were created for each of the clay types.

Abstract:

The thermoalkaliphilic Bacillus sp. strain TA2.A1 was able to grow in pH-controlled batch culture containing a fermentable growth substrate (i.e. sucrose) from pH 7.5 to 10.0 with no significant change in specific growth rate, suggesting that this bacterium is a facultative alkaliphile. However, when strain TA2.A1 was grown on non-fermentable carbon sources like succinate, no growth was observed until the external pH was > 9.0, suggesting this bacterium is an obligate alkaliphile. Growth on succinate at pH 9.5 was sensitive to both carbonyl cyanide m-chlorophenylhydrazone (CCCP) and monensin r

Abstract:

The effect of transferring fish from water at pH 7.0 to either more acid or more alkaline conditions was to reduce the maximum critical velocity of the fish. In water of pH 4.0, 5.0, and 10.0, the maximum critical velocity was only 54.5%, 66.5%, and 61% respectively of that recorded for fish in the water of pH 7.0. Thus, both acid and alkaline conditions in the water reduce the aerobic swimming capacity of trout. Exposure to acid conditions increased mucus secretion and this was associated with an increase in coughing and breathing frequency in resting fish. Coughing rate increased from 41/hr

Abstract:

The oral cavity is the most complex and accessible microbial ecosystem in the human body. It is the entrance to the respiratory and gastrointestinal tracts and, as such is exposed to unique environmental constraints. The human mouth is home to a myriad of microorganisms, many of which are exclusively found in this unique habitat. These microbial inhabitants can establish themselves and thrive in this environment by attaching to the various surfaces of the oral cavity. Following attachment, they form three-dimensional, complex and highly-integrated microbial communities. Despite their complexit

Phosphate is an essential but often growth-limiting nutrient for bacteria. At low concentrations of phosphate in the growth medium, bacteria induce high-affinity uptake systems for phosphate, and this is usually the ABC-type phosphate specific transport system Pst.

The reasons for the presence of multiple copies of pst genes in pathogenic mycobacteria are not understood, and

The concept of maximal oxygen consumption (VO2 max) implies that there is a limit to the amount of oxygen that can be consumed by an organism in a given time. Many attempts have been made to delineate exactly what factor or factors are limiting to VO2 max. Current models focus on the steps over which oxygen must traverse in order to get from the ambient air to the mitochondria. However, no model has addressed the issue of whether or not carbon dioxide flux may impose a limit to VO2 max.

RESUMO: O corpo carotídeo (CB) é um pequeno órgão sensível a variações na PaO2, PaCO2 e pH. As células tipo I (células glómicas) do corpo carotídeo, as unidades sensoriais deste órgão, libertam neurotransmissores em resposta às variações dos gases arteriais. Estes neurotransmissores atuam quer em recetores pré-sinápticos, localizados nas células tipo I, quer em recetores póssinápticos, localizados nas terminações do nervo do seio carotídeo, ou em ambos. A activação dos recetores pré-sinápticos modula a atividade do corpo carotídeo, enquanto que, a activação dos recetores pós-sinápticos, de

No primeiro experimento, canais radiculares de dentes bovinos foram instrumentados. Uma cavidade de 4 mm de comprimento, 2 mm de largura e 0,5 mm de profundidade foi confeccionada no terço médio/apical radicular de cada amostra. A abertura coronária e a superfície externa radicular fo

Abstract:

La vía secretora se caracteriza por la acidificación progresiva de sus orgánulos, este gradiente es crucial para funciones tales como la modificación postraduccional de proteínas o el trafico de membranas. El principal responsable de generar y mantener este gradiente es la H+-ATPasa vacuolar (V-ATPase), que transporta protones desde el citosol hacía el interior del Golgi. Esta bomba está compuesta de dos dominios, el dominio V1 y el V0, a su vez ambos están formados por varias subunidades. Se ha descrito que las subunidades B y C del dominio V1 contienen dominios de unión a actina. Existen si

MATERIALS AND METHODS: Flat mid-coronal dentin surfaces of extracted third molars (n = 28) were subjected only to grinding with a 600-grit SiC paper for 1 min (sound dentin S, n = 14) or additionally to erosive pH cycling with a cola-based soft-drink (eroded dentin E, n = 14).
