Mass internal

The first DNA preparations in this part of the study was PCR product - DNA of Chlamydia trachomatis 17 > bp), in the presence of a smaller by molecular mass internal control of human DNA. After migration the gel was exposured for 5, 30, 300 and 600 seconds by transilluminator Vilber Lourmat, equipped with 6 UV lamps with irradiance W = 0,24 W/m2 and 254 nm filter. The degree of structural integrity loss of amplificated DNA was evaluated by the decrease of brightness intensity of the of the bands processed by using the tools of "ImageJ" computer program. [Pg.191]

Different technical solutions are used in the temperature control of industrial reactors. The heat carriers mentioned in Section 9.2.f may be used by different technical means the direct way whereby the heat carrier is directly mixed with the reaction mass, internal or external coils, jacket, simple circuits, and indirect systems with a double circulating system. These techniques with their advantages and drawbacks, in terms or process safety, are reviewed in the following sections. [Pg.208]

The state of a system is defined by its properties. Extensive properties are proportional to the size of the system. Examples include volume, mass, internal energy, Gibbs energy, enthalpy, and entropy. Intensive properties, on the other hand, are independent of the size of the system. Examples include density (mass/volume), concentration (mass/volume), specific volume (volume/mass), temperature, and pressure. [Pg.4]

In the previous section we used the result dS = 0 to identify the equilibrium state of an initially nonuniform system constrained to remain at constant mass, internal energy, and volume. In this section we explore the information content of the stability criterion... [Pg.276]

In CFAST, a set of equations that predict state variables (pressure, temperamre, etc.) are solved based on the enthalpy and mass flux over small increments of time. These equations are derived from the conservation equations for mass, momentum, energy and the ideal gas law together with plume models, vent flow equations, radiation and combustion models. Forney and Moss reviewed that there are 11 variables to be solved the mass, internal energy, density, temperature and volume for the upper and lower layers (Mu, Eu, qu, Tu, Vu and ML, EL, qL, TL, VL), and the pressure R Because there are seven constraints, any four of those variables have to be chosen as solution variables. The four variables solved are the pressure... [Pg.903]

A compartment is divided into two control volumes, a relatively hot upper layer and a relatively cool lower layer, as illustrated in Fig. 4. The gas in each layer has attributes of mass, internal /energy, density, temperature, and volume denoted respectively by m, Ei, ni, Ti, and Vi where i = Lfoi the lower layer and / = U for the upper layer. The compartment as a whole has the attribute of pressure P. These 11 variables are related by means of the following seven constraints (counting density, internal eneigy and the ideal gas law twice, once for each Iayer)[14]. [Pg.903]

The composite figures of pressure, mass, internal fluid, and external shell temperatures indicate no unusual characteristics in the recorded parameters such as were noted previously in the 20% fill trial. However, a detailed frame-by-frame analysis of the video record clearly shows that the fast fracture phase of vessel failure was preceded, at about 1 to 2 seconds (approximately 25 to 50 video frames), with the formation of a crack that permitted a vapor and then two-phase discharge to occur through the rupture. [Pg.477]

The chemical potential is the driving force for the change in the number of molecules in a chemical process. The molecules of kind i will decrease in number spontaneously as we approach equilibrium. If G decreases when the number of molecules of kind i is decreased, Pi is positive. As is the case with temperature and pressure, and heat capacity, the chemical potential is an intensive property, which is independent of the size of the system. Extensive properties or quantity properties, on the other hand, are volume, mass, internal energy, and free energy, which depend on the amount of molecules, that is, the size of the system. [Pg.152]

It should not be an eluent that is considered an environmental contaminant. It is usually grouped with analyte elanents of a similar mass range. For example, a low-mass internal standard is grouped with the low-mass analyte elements, and so on, up the mass range. [Pg.133]

We can just as well describe the system using the entropy or the internal energy instead of looking at the free energy. For example, with the mass internal energy e, we obtain ... [Pg.43]
