The correction of the basis set superposition error by the counterpoise method has been investigated at the SCF level for the weak H-bonded water-formamide complex and the results have been compared with the uncorrected results at the SCF, post SCF and semi-empirical AM1 and MNDO levels. Our particular concern has been the determination of the three optimized relative degrees of freedom and the relative stability of three C(s) geometrical conformations. The conclusions are that the counterpoise correction weakly conditions the variation in the degrees of freedom and the relative stabilities of the three conformers. The correction is obviously inadequate to describe intramolecular deformation. [less ▲]

Rationale: The place conditioning procedure is increasingly used to study relapse in drug seeking in mice. However, the retention course of drug-induced place preference has not been systematically characterized. Methods: The effects of cocaine doses and number of conditioning trials on both the magnitude and the persistence of cocaine-induced conditioned place preference (CPP) were investigated in C57BL/6J mice. Twelve groups of animals were injected with saline, 4, 8 or 12 mg/kg cocaine (i.p.) and submitted to an unbiased counterbalanced place conditioning protocol including one, two or four drug-pairing sessions. Subsequently, the animals were tested at various time intervals after the last conditioning session. Results: One cocaine-pairing session was insufficient to induce a CPP. Two and four pairing sessions resulted in significant place preferences of similar magnitude for all tested doses of cocaine, the place preference induced by the greatest number of pairing sessions being the strongest. In the two-pairing groups, place preference lasted less than 14 days for any tested dose of cocaine. In contrast, all four-pairing groups still showed significant place preference 28 days after the last conditioning session. However, the magnitude of cocaine place preference slowly declined at a rate that was dependent upon cocaine dose. On the 35-day post-conditioning interval, only the 12-mg/kg cocaine group still displayed a significant place preference, whereas place preference was undetectable at 42 and 56 days post-conditioning for all groups. Conclusions: The number of cocaine-pairing sessions, but not cocaine dose, affected the magnitude of cocaine place preference in mice when tested 1 day after the last conditioning session. In contrast, both cocaine doses and the number of pairing sessions affected the persistence of cocaine place preference. Overall, these results demonstrate that cocaine-induced place preference is a long lasting phenomenon that is strongly affected by the number of drug-pairing trials. [less ▲]

Undesirable stiction, which results from contact between surfaces, is a major failure mode in micro,electro-mechanical systems (MEMS). In previous works, a statistical rough surfaces interaction,model, based on Maugis and Kim formulations has been presented to estimate the adhesive forces in MEMS switches. In this model, only elastic adhesive contact has been considered. However, during the impact between rough surfaces, at pull-in process for example, plastic deformations of the rough surfaces cannot be always neglected especially for the MEMS with metallic contact surfaces. In the present work, a new micro-model predicting the adhesive-contact force on a single elasticplastic asperity interacting with a rigid plane is presented. This model will be used later on for the interaction between two elastic-plastic rough surfaces. The MEMS devices studied here are assumed to work in a dry environment. In these operating conditions only the Van der Waals forces have to be considered for adhesion. [less ▲]

The authors have evolved the standard solar models taking account of the electrostatic correction in the equations of state and the Los Alamos Opacity Library, and computed their eigenfrequencies for p-mode and g-mode oscillations. The contribution of that correction to the pressure is up to several percent in the convective zone, and the present equilibrium models thus obtained have deeper convective zones than the conventional models. These improvements in the equilibrium model reduce the discrepancies between the theoretical frequencies and the observations concurrently for p-mode oscillations with low and high degree l. Theoretical frequencies of g-modes with low l are significantly higher than the observational ones. [less ▲]

OBJECTIVES: To compare the values of the urodynamic parameters of the lower portion of the urinary tract and vaginourethral measurements obtained during the phases of the estrous cycle in dogs and determine possible functional or anatomic modifications of the lower portion of the urinary tract associated with those phases. ANIMALS: 7 adult female Beagles. PROCEDURE: Urethral pressure profilometry, diuresis cystometry, and vaginourethrography were performed in each dog during proestrus; estrus; early, mid, and late diestrus; and early and late anestrus. The maximum urethral pressure (MUP), maximum urethral closure pressure (MUCP), urethral functional and anatomic profile lengths (UFPL and UAPL, respectively), integrated pressure, threshold pressure, threshold volume, compliance, urethral length, and vaginal length and width were measured. RESULTS: For all measurements, significant interindividual variation was detected. Integrated and threshold pressures, APL, and each morphometric value significantly increased from late anestrus to proestrus. Compared with other phases, MUP, MUCP, and integrated pressure values were significantly lower in estrus and early diestrus; UAPL and UFPL values were significantly lower in late diestrus. At each cycle phase in old dogs, MUP, MUCP, threshold pressure, and vaginal length and width were significantly lower (except in proestrus for vaginal measurements) and threshold volume and compliance values were significantly higher, compared with middle-aged dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Urodynamic and morphometric measurements of the lower portion of the urogenital tract are affected by the changes in hormonal balance that occur during the estrous cycle. In sexually intact female dogs, estrous phase determination is important for the interpretation of urodynamic data. [less ▲]

Influence of the fertilization type, the day in the paddock and the month on nitrogen rejections in dairy cows. The present study aims to quantify nitrogen (N) rejections in dairy cows on a rotational grazing system with different types of fertilization (compost, slurry and mineral N) at two different days in the paddock (days 3 and 5) and during two different periods (June and September). Grass yield and height were measured along with the chemical composition. The live weight was recorded when the cows moved into the paddock and milk yields was recorded at each milking. N intakes were measured on the basis of the energy requirement. When the cows were in the paddocks, individual samples of faeces and urine were collected to assess N rejections. The urea content in milk from the tank or from the individual cows was also measured. N intake was higher on day 3 than on day 5 and in September as compared with in June but was not influenced by the fertilization. The amount of N produced in milk was not influenced either by the fertilization, by the day on the paddock or by the month. The amount of urinary N was significantly higher in the N mineral group than in the two other groups. The N excretion in faeces and urines was higher on day 3 than on day 5. In June, the N excretion by the urine was lower than in September while the N excretion by the faeces was higher. Equations were calculated in order to estimate the N excretion by the urine in grazing dairy cows from the urea content in milk of a group of cows. [less ▲]

Several studies provide considerable insight into the role that frequency plays in language development. However, no study has investigated the direct relationship between frequency and grammatical acquisition in children with specific language impairment (SLI). In this study, we focus specifically on the influence of the frequency of functional words on the ability of children with SLI to produce grammatical constructions based on the children's own previous production but containing previously unused functional words. To test our hypothesis, the children were administered an imitative repetition task, tailored to their current level of language development. Results showed that children with SLI performed more poorly than language-matched children with typical language development. The difference between the two groups was more marked when the previously unused functional words were infrequent rather than frequent. Consequently, it would seem that the token frequency of functional words influences grammatical acquisition in children with SLI. The results and their implications for linguistic theories are discussed. [less ▲]

Quaternization of the end-groups of α,ω-(dimethylamino)polyisoprenes with monofunctional, difunctional and trifunctional halides (iodides and bromides) has been undertaken on polymers of different molecular weights (Mn = 6000 and 38000 gmol-l). The thermal stability of the ammonium end-groups is somewhat better when iodide counteranions are present. Quaternization increases the T~ of the material. This effect is more pronounced for low molecular weight chains, especially when a short alkyl group quaternizing agent is used. However, the size of the alkyl or aryl radical has a minor effect on polymer Tj when difunctional quaternizing agents are used. Nevertheless, the modulus of the rubber-like plateau of materials with difunctional agents is higher than with monofunctional quaternizing agents, owing to coupling reactions between the chain-ends. Rheological measurements indicate that the quaternized low molecular weight polyisoprenes exhibit an Arrhenius-type temperature dependence characterized by activation energies which vary between 121 and 146kJmol-1 and suggest that the relaxations attributed to dipole-dipole interactions dominate over long chain entanglements.
