Kinetic behavior of the two-enzyme system (lipase-lipoxygenase) in biphasic media (curve c in Fig. 5) is compared with kinetics of lipoxygenase in the same biphasic medium (b) and in an aqueous medium (a). These curves demonstrated that the configuration of the media influences the production rate of HP. As previously stated, lipoxygenase in biphasic media has an apparent kinetic behavior different from that in aqueous media (see difference between curves a and b in Fig. 5). [Pg.574]

The polar media influences the reaction of peroxyl radicals with ether as on the reaction of two polar reagents [10] and on chain generation by the reaction of ether with dioxygen as reaction with the polar TS. [Pg.308]

All reactions collected in Table 19.6 are slow. They occur with rate constants that are sufficiently lower than the rate constants of diffusion in polymer, as well as the frequency of reactant orientation in the cage (vor =vrx P). Hence, physical processes are not limited by the rates of these reactions. However, polymer media influences the kinetics of these reactions. [Pg.662]

Polymer media influences the activation energy of the bimolecular reaction and causes the effect of reactivity leveling (see earlier)... [Pg.671]

Kinetics of initiated radical polymerization of styrene is well studied at the initial stages. At the high-conversion of polymerization the growth of viscosity of media- influences the mechanism and kinetics of process greatly (12),In our research we have attempted to obtain tne empirical dependence of some rate constants of initiated polymerization of styrene on conversion with the aim of using them at mathematical simulation of the process. [Pg.214]

It is clear from the above formula that the highest harmonics will be observed with atoms of high ionization potential, such as He. Unfortunately, the intensities of these higher harmonics are considerably lower than the plateau harmonics of Ne and Xe. One might also contemplate using ionized atoms. However, the intensity of the harmonics from ions are considerably lower due to the reduced efficiency of the single-ion response and to the poorer phase matching in ionized media, influenced by the free electron dispersion. [Pg.24]

Analysis of the liquid media influence on reaction (37.16) based on the experimental and theoretical studies shows that polar aprotic solvents (acetone, acetonitrile, etc.) can inhibit this process and the effective value increases by 20-30 kJ/mol (Table 37.6) [39]. [Pg.474]

PEO, a poloxamer, resulted in a pH-sensitive as well as a thermosensitive hydrogel. Determan et al. (2007) loaded this hydrogel with lysozyme and observed its release kineties in vitro. They found that pH of the release media influenced the release rate of the lysozyme from the hydrogel, specifically in that an increase in pH resulted in a decrease in release rate (Determan et al. 2007). [Pg.277]

Because of low energy of [9.60, 9.61] processes, it is not possible to assign any solvents strictly to a universal or specific group. That is why only a limited number of binary solvents can be used for the analysis of universal media influence on conformer equilibrium constants. It is interesting to note that over the years, the real benzene basicity in liquid phase has not been sufficiently investigated. There were available conformer equilibrium constants in benzene, toluene, etc., highly differing from those in other low-polar media. Such phenomenon is proposed to be called the benzene effect . ... [Pg.531]

A hypothesis is developed to explain the formation mechanism of the ROS ring by the polymer rheology in high pH caustic media influenced by the microscopic heterogeneity of porous medium. [Pg.263]

There were some early reports that reaction media influences the polymerizations of vinyl chloride in aliphatic aldehydes at 50°C [80, 81]. This was not confirmed in subsequent studies [82-84]. Subsequently, the rate of polymerization was shown to be influenced by the pH of the reaction medium in polymerizations of monomers such as methacrytic acid (MAA) [85, 88]. Also, the rate of polymerization and solution viscosities increase in polymerizations of acrylamide and acrylic acid with an increase in water concentration [83]. It is not quite clear whether this is due to increases in the speeds of propagations or due to decreases in the termination rates. In the free-radical polymerization of vinyl benzoate, the rate of propagation varies in different solvents in the following order [88, 89] ... [Pg.87]

Clearly the societal reaction - even that portion of it reflected in the mass media - is not homogeneous. One cannot assume that the inventory images and the themes discussed in this chapter, diffused outwards to be absorbed symmetrically by all of society. Standard research on mass media influences indicates how complicated and uneven this flow is, and basic questions need to be asked about the representativeness of these images and themes and whether significant differences exist in terms of age, sex, social class, region, political affiliation and so on. The already processed images of deviance are further coded and absorbed in terms of a plurality of interests, positions and values. [Pg.66]

Matty of the industrial processes and work activities that are carried out have an effect on people both inside and outside the workplace. Escaping chemicals, noise, dust and dumping of industrial wastes are just a few examples. There is undoubtedly a strong public and media influence in the drive for safer and healthier work. [Pg.9]

Media influence. This can be positive or ne tive. Quite often the media will warn of a risk before parliamentarians and judges, as social arbiters, act to increase people s protectioa But the media can also create unbalanced attitudes, panic or lysteria... [Pg.50]

Standardization of medium is an important parameter in in vitro tissue culture technology since the composition of the culture media influences both the biomass yield as well as secondary metabolite production. Composition of the medium, culture conditions, and exogenous phytohormone combinations together influence the metabolite accumulation in the cell. Composition of macro- and micronutrients, nature and amount of carbon source, and level of total nitrogen has been found to play a vital role in the production of secondary metabolites. [Pg.470]

A strong trust can overcome many other factors such as media influence, lack of knowledge, uncertainty, complex technologies, etc. Trust can be seen as a kind of compensation factor (Huang et al., 2013) that people can use to overcome other influential perception modifiers (Williamson Weyman, 2005). [Pg.457]
