Considerable neuromuscular involvement also occurs in patients with AIDS.47 100 Peripheral neuropathies, myopathies, and various CNS manifestations (dementia, other psychological manifestations) can occur directly from HIV infection or secondarily, due to some other opportunistic infection.31 85 100 Likewise, peripheral neuropathies are a common side effect of certain anti-HIV drugs (didanosine, stavudine, zal-citabine), and myopathies are a side effect of zidovudine therapy.63 Patients with HIV disease often have painful symptoms such as joint pain, back pain, and pain related to neuropathies and myopathies.100 Hence, HIV disease can often be regarded as a degenerative neuromuscular disorder from the standpoint of a rehabilitation professional. Therapists can therefore help improve function and decrease pain in patients with HIV infection and AIDS.1 33... [Pg.536]

The decrease in < 0 < (t) > depends on the slope of the potential surface at the point at which the wavepacket is initially placed. The slope of the potential in the Qy direction is steeper on the positive Qx side of the surface than on the negative Qx side. When the slope in the Qy dimension is large, the Qy part of the two-dimensional wavepacket will rapidly change its shape and < 010 (t) > will decrease rapidly. Therefore, for a positive Qx displacement in the coupled potential, the autocorrelation function will decrease more rapidly than it would for a negative displacement. [Pg.183]

In the simplest version, the Powell method utilises the unit vectors as a set of directions. Using one-dimensional minimisation, the algorithm moves along the first direction to its minimum, then from there along the second direction to its minimum, etc. The whole process is repeated as many times as necessary until the function stops decreasing. All the direction set methods consist of prescriptions for updating the set of directions as the method proceeds. [Pg.343]

The second part of the principle regards the evolution in the direction of the improved or increased degree of ideality. This increase will be a result of two interrelated processes. First, it will be the growth of the useful functions (the nominator in the ideality ratio formula). Second, it will be the parallel reduction of the harmful functions (the denominator in the ideality ratio formula). In the case of internal combustion engines, their useful functions are constantly growing, for example their power and torque, while their harmful functions are decreasing, for example their CO2 pollution and noise. [Pg.325]

It is clear that the reduced gradient direction decreases the objective function. It cannot be considered to be either the only one or the best one. [Pg.462]

The third direction which was the concept of diameter reduction has led to the group of nano fibers, although such fibers can also be built up in a bottom-up way [1]. This group is the combination of the two former directions because the aim in this case is both increased strength and functionalization. The decrease of fiber diameter generally leads to an increased strength because of the so-called size-effect [2]. This phenomenon revived the development of nanocomposites and nano-reinforcements where the typical size of reinforcement is in the nanometer or submicron scale. [Pg.302]

There is increasing evidence that niacin has potential benefit in decreasing inflammation, an important part of atherosclerosis. This may be mediated in part by ability of niacin to increase HDL or direct anti-inflammatory effect independent of the HDL (Vaccari et al. 2007a,b). For instance, administration of extended-release niacin (1000 mg/day) in 52 individuals with the metabolic syndrome was shown to be associated with a marked change of carotid intima-media thickness (IMT), improvement of endothelial function and decrease in high sensitivity C-reactive protein (Thoenes et al. 2007). [Pg.673]

The calculated resonance energies (RE) of 12 (equation 11) and of benzene (equation 2) are 53.1 kcalmoD and 63.8 kcalmoD, respectively (at CCSD(T)/DZP//CISD/DZP), indicating that 12 has 83% of the aromaticity of benzene". Similar results were obtained with lower levels of theory , but this is probably fortuitous. The addition of polarization functions changes the 12/benzene RE ratio from 84% at DZ to 99% at DZP, while electron correlation acts in the opposite direction, decreasing the above ratio to 83%. The existence of aromatic stabilization in 12 can also be concluded from the large difference of 27 kcalmol (MP2/6-31G //MP2/6-31G ) in the stability of the Si=C double bonds in the aromatic 1,3,5-trisilabenzene and the non-aromatic 1,3,5-silacyclohexadiene i.e. AE = —35.3 and 8.5 kcalmoD for equations 12 and 13, respectively. The calculated r-atomic populations and 7r-bond-orders point to a similar degree of aromaticity in CeHe, CsSisHe and SieHe ". [Pg.21]

A large majority of edge compnters on the Internet are probably snsceptible to attack and subversion at any given time. Becanse it is not economically feasible to harden all of these hosts, they are isolated from the rest of the Internet and many potential attacks by breaking the end-to-end model. It is impossible to mount a direct attack on a computer that cannot be reached. The trade-off between security and functionality does decrease the envisioned power and functionality of the Internet somewhat. Often, there is no satisfactory trade-off the choice is between an unsafe service and no service at all. [Pg.94]

The presented four main parts of a detector may be or may not be separate units. Actually, both their structures and their functions may overlap. For instance, the blocks (a) and (b) indirectly decrease noise by decreasing the active area volume. The block (b) also directly decreases noise since it increases reabsorption. [Pg.42]

The ToF-SIMS intensity variation of the most characteristic peaks of PP and PIB is shown in Fig. 8(a, b), as a function of the cumulated ion dose. For PIB, the decrease with the ion dose of characteristic fragments at 83 and 97 amu is already initiated at the first point of measurement, while for PP, the peak at 69 amu increases first to a maximum value, before decreasing. The direct decrease in the intensity of the most characteristic ions is related to the degradation of the precursor, while the maximum observed for the most important peak of PP shows competition between two different processes the degradation, and the ion formation which may be induced by the initial degradation. The close relationship between the secondary molecular ion production and the polymer degradation under the ion beam bombardment was pointed out. [Pg.658]

Preparations of nanoparticles have yielded synthesis methods that are widely used to obtain nanoparticle samples for research pinposes [3-5]. These preparations have led to detailed examinations of the opto-electronic properties of nanostmctures as they deviate from those of the bulk material. For example, the blue shift in the absorption onset as a function of decreasing nanoparticle size can be directly related to quantum confinement of excitons within the nanoparticle [6]. Due to their extremely small size and large specific surface area, nanoparticles usually exhibit unusual physical and chemical properties compared to that of bulk materials [7]. The use of polymer matrix as an environment for in situ nanoparticle growth combines, synergistically. [Pg.3]

As a function of the anisotropic orientation of aspect ratio for the montmorillonite and elastomer in the preferred direction of the flow of the injection molder, the expansion coefficient of the composite in the flow direction decreased from approximately 9.7 x 10 mm/mm°C for 0% montmorillonite content to approximately 5.3x10 mm/mm°C for 7% montmorillonite content when the ratio of compatibilizer to montmorillonite was 2. Similar values were observed for compatibilizer montmorillonite ratios of 0.5 and 1.0. [Pg.120]

The quality of the TEM pictures was poor. The dispersions appeared to be intercalated and poorly dispersed. No information was provided with regard to the alignment of the particles in relation to the direction of the applied stress. Because each polymer has a different modulus, the most useful comparison for the determination of reinforcement efficiency of the polymers with Cloisite 30B was the ratio of the modulus of the polymer with and without montmorillonite content. As the content of Cloisite 30B was increased, the polymer with the best modulus response was a function of decreasing chlorine content chlorinated PVC (3% Cloisite 30B content produced a 15% increase in modulus) PVC (5% Cloisite 30B content produced a 24% increase in modulus) chlorinated PE and PVC has similar moduli at 10% Cloisite 30B content (50% increase). Note that the modulus of the pure polymers decreases significantly as the chlorine content decreases (approximately 2400 MPa for chlorinated PVC 2000 MPa for PVC and 4 MPa for chlorinated PE). Percent elongation to failure increases from approximately 900% for the pure polymer to 1000% for chlorinated PE at 5% content of Cloisite 30B. [Pg.134]

The quantity gH indicates the direction in which the error function should decrease. By making a very small step in that direction, there is a high probability that the error function will, in fact, decrease. On the other hand, if the step is very small, then the number of function evaluations becomes prohibitively large. However, the value of the calculated data using the new parameters can be rapidly estimated using the first derivatives of these data with respect to the parameters ... [Pg.2003]

Even though SO2 has decreased substantially, it is still included in all functions, as is the effect of wet acid deposition (acid rain). NO2 is not included in any of the functions directly but is closely related to HNO3. The parameter HNO3 was significant for zinc and limestone while PMio was included in the functions for carbon sfeel, cast bronze and limestone. [Pg.691]
