BACKGROUNG: There are four main types of ingrown nail. These are distal nail embedding, juvenile (subcutaneous) ingrown nail, hypertrophy of the lateral nail fold (lip), and pincer nail. OBJECTIVE: The etiology of pincer nail may be hereditary or acquired. The mechanism of the most common form, an enlarged base of the distal bony phalanx, is discussed. METHODS: Use of roentgenogram and magnetic resonance imaging highlights exophytes of the base and dorsal hyperostosis of the distal phalanx. RESULTS: Global assessment may lead in mild cases to medical therapy. Usually, however, the lateral matrix horn must be surgically removed or cauterized by phenol. Dermal grafting under the nail matrix provides excellent long-term results. [less ▲]

The pinch point method has been developed to identify energy saving opportunities in industrial processes, The use of the composite curves allows to compute the minimum energy requirement of a process and to determine optimal heat exchange between hot urd cold streams. The use of MILP (Mixed Integer Linear Programming) optimisation method allows to extend the approach to solve combined heat and power problems. The method is applied here to determine the optimal configuration of combined cycles, It allows to maximize the mechanical power production without having to consider the heat exchangersc onfiguration in the boiler nor in the preheating section. The method is also used to compute the steam extractions or productions and their optimal pressure levels that maximize the mechanical power produced From these results, the heat exchangers network structure is then determined. Three situations are analyzed: l) the heat recovery in a classical boiler using air preheating, 2) the gas turbine combined cycle and. 3) the " isothermal" gas turbine. The " isothermal" gas turbine is an innovative promising technology that uses a partial oxydation reactor followed by a staged combustion between the expansion stages to reach a quasi isothermal profile during the expansion. This allows to reduce the exergy losses in the gas turbine. The resulting flue gases are used in a combined cycle optimized with the method presented here. Diffirent configurations are discussed We show that the structure of combined cycles may strongly differ from one to another. [less ▲]

We investigate the flux pinning and dynamic properties of superconducting vortices in an Al film with an array of magnetic bars deposited on top. The dimensions of each bar are chosen in such a way that they host a single magnetic domain. These micromagnets are distributed periodically in a rectangular array with 0.5 mu m separation parallel to the longest side of the bars and displaced laterally by a distance w. We show that, for w > Lambda, where Lambda is the effective field penetration depth, the pinning strength is almost independent of w whereas the critical temperature at zero field, T(c)(0), decreases as similar to w(-1). For w < Lambda the opposite behavior is observed, i.e. T(c)(0) seems to saturate to a nearly w-independent value and the transition from large to small w is accompanied by a large suppression of the critical current j(c) together with a clear change in the shape of the current-voltage characteristics. In particular, the substantial weakening of the pinning potential for w < Lambda gives rise to an unexpected flux flow response. The field evolution of this regime allows us to determine whether the magnetic bars induce vortex-antivortex pairs in the system. The present findings suggest that practical application of magnetic pinning centers are restricted to low field values. [less ▲]

We study the influence of artificial pinning centers on the vortex critical velocity in Al thin films deposited on top of a periodic array of Permalloy (FeNi) square rings. We demonstrate that the field dependence of the flux flow velocity strongly depends on the particular magnetic state of the rings. In particular, we find that, even when the rings are in a flux closure state, i.e. with little stray field, the vortex critical velocity shows a non-monotonic magnetic field dependence. This behaviour is in sharp contrast with the results obtained in a reference plain film, with no rings underneath. A comparison with the intrinsic strong pinning Nb films previously studied, suggests an interpretation in terms of a channel-like motion of vortices, here induced by the artificial pinning structure.

Objective: In this post hoc analysis, we examined insulin requirements and regimens, glycemic control, cardiovascular outcomes, and safety in the patients treated with insulin at baseline in the Prospective Pioglitazone Clinical Trial in Macrovascular Events study. Design: The Prospective Pioglitazone Clinical Trial in Macrovascular Events study was a double-blind, placebo-controlled outcome study (mean follow-up 34.5 months) in 5238 high-risk patients with type 2 diabetes randomized to pioglitazone (force titrated to 45 mg) or placebo. One third of the total population (pioglitazone 864; placebo 896) were receiving insulin at baseline. Results: A rapid and sustained decrease in insulin dose was observed with pioglitazone vs. a progressive increase with placebo. By study end, the mean insulin dose was lower with pioglitazone (42 vs. 55 U/d with placebo; P < 0.0001). The insulin regimen (number on insulin, need for multiple injections, and reduction in oral agents) had been simplified vs. placebo; nevertheless, a greater glycosylated hemoglobin reduction was observed with pioglitazone (-0.93%) vs. placebo (-0.45%; P < 0.0001). At the final visit, insulin had been discontinued in 9% of pioglitazone vs. 2% of placebo patients (P < 0.0001). More insulin-resistant patients (defined as poorly controlled type 2 diabetes despite high doses of insulin) in the pioglitazone plus insulin group showed the greatest glycosylated hemoglobin decline. There were nonsignificant reductions with pioglitazone relative to placebo in the cardiovascular primary (hazard ratio 0.86; 95% confidence interval 0.71, 1.04; P = 0.1198) and main secondary (hazard ratio 0.85; 95% confidence interval 0.67, 1.08; P = 0.1831) end points in insulin-treated patients. The rates of overall heart failure, edema, and hypoglycemia were higher with pioglitazone [13.5 vs 10.5% (P = 0.0489); 30.8 vs. 18.2% (P < 0.0001); and 42.1 vs 29.0% (P < 0.0001), respectively], but there were no significant differences in serious events. Conclusions: Pioglitazone use in combination with insulin resulted in a sustained improved glycemic control and allowed the treatment regimens to be simplified and the insulin doses reduced.

We calculate the low energy pipi scattering lengths a(0)(0), a(0)(2), b(0)(0), b(0)(2) and a(1)(1), the coupling of the rho to the pion g(rhopipi), the total width of the rho, the low q(2) behavior of the pion electromagnetic form factor, and the pion scalar form factor within a chiral SU(2)(f) NJL-type Lagrangian where the spin 1 rho meson is generated from a four-quark tensor interaction. Such a simple model avoids the mathematical complication related to pi - a(1) mixing. Two types of regularization are discussed, mainly affecting the values of a(0)(0) and b(0)(0). We find rather good agreement with data. The p meson described in this way does not account for the meson vector dominance model: it does not contribute to the a(0)(0), a(0)(2) scattering lengths, and the charge radius of the pion is mainly ascribed to the bare photon quark coupling. Even if the shape of the electromagnetic form factor is well reproduced, the strong increase near the rho pole does not account for the p --> pipi decay but only reflects the q (q) over bar structure of the rho.

We present a method to evaluate the pion structure functions from a box diagram calculation. Pion and constituent quark fields are coupled through the simplest pseudoscalar coupling. The gamma^* pi -> q \bar q cross-section is evaluated and related to the structure functions. We then show that the introduction of non-perturbative effects, related to the pion size and preserving gauge invariance, provides us with a straighforward relation with the quark distribution. It is predicted that higher-twist terms become negligible for Q^2 larger than about 2 GeV^2 and that quarks in the pion have a momentum fraction smaller than in the proton. We enlarge the discussion concerning this violation of the momentum sum rule, emphasizing that the sum rule is recovered in the chiral limit and also when the finite size condition is not imposed.

The pion-nucleon vertex function with an off-mass-shell nucleon is obtained through sideways dispersion relations with the P[SUB]11[/SUB] and S[SUB]11[/SUB] pion-nucleon phase shifts as only input. Contrary to the recent calculation of Nutt and Shakin, we find that the proper and improper vertex functions behave quite differently, indicating the importance of the nucleon propagator dressing. In particular the proper vertex function is found to have two poles in the unphysical region.

We define the pion-photon transition distribution amplitudes (TDA) in a field theoretic formalism from a covariant Bethe-Salpeter approach for the determination of the bound state. We apply our formalism to the Nambu-Jona-Lasinio model, as a realistic theory of the pion. The obtained vector and axial TDAs satisfy all features required by general considerations. In particular, sum rules and the polynomiality condition are explicitly verified. We have numerically proved that the odd coefficients in the polynomiality expansion of the vector TDA vanish in the chiral limit. The role of PCAC and the presence of a pion pole are explicitly shown. © 2007 The American Physical Society. [less ▲]
