Long-term results of the surgical treatment of Peyronie＇s disease with Egydio＇s technique： a European multicentre study

The long-term outcomes of 157 patients affected by Peyronie＇s disease （PD） who underwent penile straightening with Egydio＇s technique between January 2004 and December 2008 are reported. Only patients with PD who were stable for at least 6-12 months prior to surgery were enrolled in this study. Preoperative assessment included a dynamic echo colour Doppler ultrasound scan to evaluate the degree of penile deformity and the peak systolic velocity in the cavernosal arteries and an assessment of erectile function with the administration of the International Index of Erectile Function 5 （IIEF-5） questionnaire. Stretched penile length was recorded pre- and postoperatively. Surgical complications, cosmesis and sexual function, patient satisfaction and postoperative erectile function were assessed postoperatively at 3 months, I year and 2 years, respectively. After a median follow-up period of 20 months （range： 12-24 months）, we found that mild residual curvature （12%） and glans hypoesthesia （3%） were the only causes of partial dissatisfaction. No rejection of the graft was observed. All patients recovered their ability to penetrate with no difficulty. In addition, an intraoperative average increase of 2.5 cm （range： 1.7-4.1 cm） in stretched penile length was recorded, with all patients engaging in penetrative sexual intercourse. In conclusion, this procedure represents a safe and reproducible technique for the correction of penile curvature resulting from PD and yields excellent cosmetic and functional results.

Reliability Based Analysis of Ground Improvement Using a Polymeric Chemical Stabilizer

In view of the challenges posed by the nature of expansive soil to structural stability which makes it necessary in some cases to improve the soils before structures can be placed on them, there is a need to investigate modern trends in ground improvement techniques in order to determine their reliability. This study is thus aimed at using the reliability based approach to analyze the use of polyvinyl alcohol (PVA) in combination with 1,2,3,4 Butane-tetracarboxylic acid (BTCA) for ground improvement. This study is necessary given the challenges posed by the nature of expansive soil to structural stability which makes it necessary in some cases to improve the soils before structures can be placed on them. Simplex lattice design was employed to build the design of experiment before experimental investigations were carried out on the PVA-BTCA treated soft soils. Reliability indices were computed on the basis of the 28th day unconfined compressive strength (UCS) of the treated soil. Reliability index models were developed using the Scheffe’s technique and optimized using excel solver. From analysis of results, reliability model developed proved adequate at 5% level of significance. PVA-BTCA combination provided a potential reliability or probability of success of 99.936% at components combination of: 98.4256% for soil, 1.2352% for PVA, 0.3392% for BTCA and 15.9934% for water. It was therefore recommended that financial implications of using PVA-BTCA for stabilization be compared to those of conventional methods, in order to compare their performance-cost ratio.

Effect of JIN's 3-needle technique and motor function trai-ning on upper extremities motor recovery of cerebral apoplexy induced hemiplegia

Objective To observe the clinical effects on upper extremities function recovery of cerebral apoplexy induced hemiplegia by combination of JIN＇s 3-needle technique and motor function trai- ning. Methods Eight-seven cases of cerebral apoplexy induced hemiplegia were randomized into an observation group （44 cases） and a control group （43 cases）. JIN＇s 3-needle technique and motor function training were both adopted for the observation group. Three temporal acupuncture points on the affected side were selected. Three lower arm points, namely Qfichi （曲池 LI 11 ）, Waiguan （外关 TE 5） and Hegu （ 合谷 LI 4） were adopted for flaccid hemiplegia. While 3 upper arm points for relieving spasm, namely Jiquan （极泉HT 1）, Chize （尺泽 LU 5） and Neiguan （内关 PC 6） were chosen for spastic hemiplegia. Motor function training was applied alone for the control group. Treating courses for both groups were 5 weeks. And scores of Brunnstrom and FugI-Meyer assessments of the affected limbs were analyzed. Results Improvement on scores of FugI-Meyer and Brunnstrom assessments were observed for both groups after the treatment（P〈0. 05, P〈0. 01 ）. The post-treatment scores of the observation group was better than that of the control group after the treatment （ P〈0.05, P〈0.01 ）. Conclusion Treat- ment of combination of JIN＇s 3-needle technique with motor function training can obviously improve the motor function of the upper extremities of patients with cerebral apoplexy induced hemiplegia.

Kerogen Kinetic Distributions and Simulations Provide Insights into Petroleum Transformation Fraction (TF) Profiles of Organic-Rich Shales

Two hundred and fifty single first-order Arrhenius reactions are simulated to generate S2 pyrograms at three heating rates 25,15,and 5°C·min-1.The activation energy(E)and pre-exponential factor(A)of the reactions simulated follow a long-established trend of those variable values displayed by shales and kerogens.The characteristics of the transformation fraction(TF)profiles(product generation window temperatures)of the simulated single reactions are compared to the TF profiles of recorded shale pyrograms generated by multiple reactions with different E-A values lying near the defined E-A trend.Important similarities and differences are observed between the TF profile values of the two datasets.The similarities support the spread of E-A values involved in shale pyrogram best fits.The differences are most likely explained by the complexity of the multiple kerogen first-order and second-order reactions contributing to the recorded shale pyrograms versus the simplicity and crispness of the single first-order reactions simulated.The results also justify the validity of using the previously described“variable E-A pyrogram-fitting method”of multi-heating-rate shale pyrograms enabling optimizers to choose multiple reactions from an unlimited range of E-A values.In contrast,further doubt is cast on the validity of the constant-A pyrogram-fitting method used by the Easy%Ro technique,in that a distribution of reactions with a single A value is unlikely to represent the complex variety of kerogen macerals observed in shale formations.TF profiles generated by the variable E-A pyrogram-fitting method lie close to the established E-A trend and are likely to provide more realistic TF generation window temperatures than TF profiles generated by the constant-A pyrogram-fitting method.

Optimal analytical and numerical approximations to the(un)forced(un)damped parametric pendulum oscillator

The(un)forced(un)damped parametric pendulum oscillator(PPO)is analyzed analytically and numerically using some simple,effective,and more accurate techniques.In the first technique,the ansatz method is employed for analyzing the unforced damped PPO and for deriving some optimal and accurate analytical approximations in the form of angular Mathieu functions.In the second approach,some approximations to(un)forced damped PPO are obtained in the form of trigonometric functions using the ansatz method.In the third approach,He’s frequency-amplitude principle is applied for deriving some approximations to the(un)damped PPO.In the forth approach,He’s homotopy technique is employed for analyzing the forced(un)damped PPO numerically.In the fifth approach,the p-solution Method,which is constructed based on Krylov–Bogoliúbov Mitropolsky method,is introduced for deriving an approximation to the forced damped PPO.In the final approach,the hybrid Padé-finite difference method is carried out for analyzing the damped PPO numerically.All proposed techniques are compared to the fourth-order Runge–Kutta(RK4)numerical solution.Moreover,the global maximum residual distance error is estimated for checking the accuracy of the obtained approximations.The proposed methodologies and approximations can help many researchers in studying and investigating several nonlinear phenomena related to the oscillations that can arise in various branches of science,e.g.waves and oscillations in plasma physics.
