The scientific targets of the EUROSUNMED project are the development of new technologies in three energy field areas, namely photovoltaics (PV), concentrated solar power (CSP) and grid integration (GI), in strong collaboration with research institutes, universities and SMEs from Europe in the north side of the Mediterranean sea and from Morocco and Egypt from the south of the sea. The focus in PV will be on thin film (Si, CZTS) based solar cells and modules while the goal in CSP field is to design and test new heliostats as well as novel solutions for energy storage compatible with these technologies. The project aims at producing components that will be tested under specific conditions of MPC (hot climate, absence of water, etc.). Such investigations are complemented with studies on grid integration of energy sources from PV and CSP in Morocco and Egypt context. Additionally, the consortium envisages to train PhD students and Post-Docs in these interdisciplinary fields in a close and fruitful collaboration between academic institutions and industry from EU and MPCs. The consortium is well placed around leading academic groups in materials science and engineering devices and equipments for the development of PV and CSP, and also in the promotion of the renewable energies in general. Moreover, technology transfer and research infrastructure development in the targeted areas will be provided. Disseminating the results of the projects will be done through the organization of summer schools, workshops and conferences towards large public from universities, engineering schools and stakeholders involved in the three selected energy areas and beyond. Another outreach of the project will be the proposal for a roadmap on the technological aspects (research, industry, implementation) of the PV, CSP and grid area as well as on the best practice for the continuation of strong collaboration between the EU and MPCS partners and beyond for for mutual interest and benefits.

BACKGROUND: The modified Karydakis flap and the modified Limberg flap are commonly used in the surgical management of sacrococcygeal pilonidal sinus disease. OBJECTIVE: The study aimed to compare short- term results of these techniques. DESIGN: The modified Karydakis flap and the modified Limberg flap were compared in a randomized controlled trial. SETTINGS: The study was conducted in the day-case surgery department of a large academic teaching hospital in Alexandria, Egypt, from February 2009 through September 2011. PATIENTS: Patients undergoing surgery for chronic sacrococcygeal pilonidal sinus disease were eligible for the study. Patients with sepsis were eligible only after aggressive treatment to eliminate sepsis. INTERVENTIONS: Patients were randomly allocated to undergo surgery with either the modified Karydakis flap or the modified Limberg flap. MAIN OUTCOME MEASURES: The primary end point was operative time. Secondary endpoints included proportion of patients with postoperative complications, proportion of patients who were satisfied with the cosmetic results, and the rate of recurrence. LIMITATIONS: Follow-up times were not sufficient to evaluate long-term recurrence rates. RESULTS: Of 154 patients screened, 125 were enrolled, and 120 patients completed the study. The median operative time was significantly shorter in patients with the modified Karydakis flap than in those with the modified Limberg flap: 33 (range, 28-40) min vs 52 (range, 48-62) min; p < 0.001). No significant differences were found between study groups regarding overall complication rate (23% vs 40%, p = 0.08), wound infection (3% vs 5%, p > 0.99), subcutaneous fluid collection (5% vs 0%, p = 0.24), or hypoesthesia (10% vs 23%, p = 0.09). Full-thickness wound disruption was encountered in 9 patients (15%) in the modified Limberg group vs no patient in the modified Karydakis group (p = 0.003). The median follow-up duration was 20.5 months in each study group. One patient (2%) in the modified Karydakis group developed recurrent disease vs 2 patients (3%) in the modified Limberg group (p > 0.99). In the modified Karydakis group, 58 patients (97%) were satisfied with the cosmetic outcome and were willing to recommend the operation to others vs 43 patients (72%) in the modified Limberg group (p < 0.001). CONCLUSIONS: Both techniques provide effective treatment for pilonidal sinus disease and can be performed safely as day-case surgery. The modified Karydakis flap is associated with significantly shorter operative time, a lower full-thickness wound disruption rate, and a higher patient satisfaction rate. © The ASCRS 2013.

The spectral-amplitude-coding optical code-division multiple-access (SAC-OCDMA) technique is a vital candidate for future optical networks. Until now, there has been no exact analysis for the performance of systems using these techniques, and most researchers use upper and/or lower bounds to obtain the bit-error rate (BER) of these systems. In this letter, a more accurate analysis of the statistics, in terms of the mean and variance, of the decision current in SAC-OCDMA receivers is developed. These statistics are used to evaluate the BER of SAC-OCDMA techniques based on the Gaussian approximation method. Furthermore, the derived BER is evaluated numerically, for two different types of SAC-OCDMA codes, and is shown to fit properly between the upper and lower bounds of the BER. © 2012 IEEE.

Objective: To learn the incidence of erectile dysfunction (ED) after pelvic fracture urethral injury (PFUI) and to identify the related risk factors. Methods: Patients who had sustained a PFUI from 1984 to 2010 were identified from database and invited to participate in the study. All responders were queried after a minimum of 2 years from the time of trauma to assess their erectile function (EF) using the EF domain of the International Index of Erectile Function (IIEF). Medical records and imaging studies were reviewed with a focus on 6 variables that may predict ED. Univariate and multivariate analyses were used to identify parameters predictive of ED. Results: Overall, 90 patients participated in the study, among whom 40 (44%) had ED. On univariate analysis, 4 variables were significant factors for prediction of ED, whereas on multivariate analysis only 3 factors remained strong and independent predictors, namely diastasis of pubic symphysis, lateral displacement of prostate, and long urethral gap. The results of analyses showed that these 3 variables were significant at odds ratios (ORs) of 15.9, 6.9, and 2.0, respectively. Conclusion: The development of ED after PFUI can be predicted by 3 factors, namely diastasis of pubic symphysis, lateral prostatic displacement, and long urethral gap. Pubic diastasis has the highest predictive accuracy. A tendency for higher risk of ED could be observed after bilateral rami and Malgaigne's fractures, but they failed to reach the level of significant predictors on multivariate analysis. No relationship was evidenced between ED and age at traumatism. © 2013 Elsevier Inc. All Rights Reserved.

Developing effective vaccines is an important weapon in the battle against potential pathogens and their evolving antibiotic resistance trends. Several vaccine delivery vectors have been investigated among which the generally regarded as safe (GRAS) Lactococcus lactis has a distinguished position. In this review, different factors affecting the efficacy of L. lactis-based vaccines are discussed. In addition, the issues of biological containment and pharmaceutical quality assurance of L. lactis vaccines are highlighted. These issues are critical for the success of medical translation of L. lactis-based vaccines from research laboratories to clinical use by ensuring consistent manufacturing of safe and efficacious vaccines. © 2011 Elsevier Ltd.

A fertile technique, for increasing single-user throughput while keeping a constraint on the light pulsewidth, is proposed for spectral-amplitude-coding optical code-division multiple-access (SAC-OCDMA) systems. In this technique, two-level M-ary overlapping pulse-position modulation (M-OPPM) scheme is adopted and each user is assigned two orthogonal code sequences to represent these two levels. The code sequences are selected from a minimum cross-correlation code set. The bit error rate (BER) of the proposed system is derived, taking into account the effects of phase-induced intensity noise, shot noise, and thermal noise in addition to the multiple-access interference. The BER performance of this system is compared to other systems adopting M-PPM and OOK schemes under same pulsewidth constraints. Our results reveal that, while keeping the BER well below a prescribed threshold, the proposed M-OPPM SAC-OCDMA system achieves higher transmission rate as compared to both M-PPM and OOK SAC-OCDMA systems under same constraints. Specifically the transmission rate of a single user of the proposed system can be increased by about 34.44% as compared to traditional systems. © 1983-2012 IEEE.

Purpose We sought to determine the incidence of erectile dysfunction following pelvic fracture urethral injuries in children, and to identify the related causes and risk factors. Materials and Methods All consecutive children who had undergone repair of a pelvic fracture urethral injury between 1980 and 2010 were invited to participate in the study. All responders were queried after a median of 13 years (range 3 to 28) following trauma to assess erectile function using the erectile function domain of the International Index of Erectile Function. Patients who had erectile dysfunction underwent penile duplex ultrasonography. Medical records and imaging studies were reviewed with a focus on 4 variables, ie pattern of pelvic fracture, pubic diastasis, prostatic displacement and urethral gap length. Univariate and multivariate analyses were used to identify parameters predictive of erectile dysfunction at puberty. Results A total of 60 patients participated in the study, of whom 28 (47%) had erectile dysfunction. On univariate analysis all 4 parameters were significant predictors of erectile dysfunction, while on multivariate analysis only 2 parameters remained strong and independent predictors, namely urethral gap length 2.5 cm or greater and prostatic displacement in a lateral direction. Duplex ultrasound revealed the cause of erectile dysfunction as arteriogenic in 19 patients (76%), arteriovenogenic in 2 (8%) and likely neurogenic in 4 (16%). Conclusions For every 2 children sustaining a pelvic fracture urethral injury 1 will exhibit erectile dysfunction at puberty. The risk of erectile dysfunction is appreciably increased in the presence of a long urethral gap and/or lateral prostatic displacement. The cause of erectile dysfunction is most commonly primarily arteriogenic and less commonly neurogenic. © 2014 by American Urological Association Education and Research, Inc.
