AbstractThis work presents a synthesis of the present-day knowledge on both emerged and submerged carbonate platforms of the Guadeloupe archipelago. Onshore and offshore data acquired during the KaShallow project are presented. Since the early Zanclean, some isolated platforms developed onto a Jurassic to Tortonian basement which displayed reliefs inherited from a major extensional tectonic episode dated from −8 to −5 Ma. Marie-Galante, Grande Terre and the southern shelf of Grande-Terre show strong similarities with Zanclean to Gelasian red-algal facies upward changing into early Calabrian coral facies. A major erosional unconformity (SB2) was recognized and allows to distinguish two early Calabrian formations (Calcaires à Agaricia Formation and Calcaires à Acropora Formation). The final emersion of these platforms is late Calabrian. The La Désirade platform displays Zanclean to early Piacenzian red-algal facies upward changing into coral facies. This platform emerged as soon as in the late Piacenzian. The island subsided again in relation with later extensional tectonic episode and early Calabrian reef platform then unconformably deposited. The Colombie bank deposits comprise Pliocene basinal deposits overlain by late Calabrian coral reefs. The Flandre bank might have emerged synchronously with La Désirade but was drowned only in the late Pleistocene-Holocene interval. Four extensional tectonic episodes have been identified in the late Miocene-Recent interval. Their effects depend on the location of the platforms within the fore-arc.

Published: March 2013

SUMMARYThe incorporation of hydrophilic and acidic resin monomers substantially improved the initial bonding of contemporary etch-and-rinse (ER) and self-etch (SE) adhesives to intrinsically wet dental substrates, providing quite favorable immediate results, regardless of the bonding approach used. However, in the long term, the bonding effectiveness of most simplified ER and SE adhesives drop dramatically. This review examines the fundamental processes that are responsible for the aging mechanisms involved in the degradation of the resin-bonded interfaces and some possible clinical approaches that have been effective in minimizing or even preventing the degradation of the adhesive interfaces produced with simplified adhesives. The incorporation of some of the feasible approaches - described in this review - may improve the quality of the adhesive restorations performed in clinical practice, while manufacturers develop bonding materials that are less susceptible to the aging mechanisms present in the oral environment.

Published: March 2013

AbstractIn this paper we have generalized $$F^{\bar \xi }$$-calculus for fractals embedding in ℝ3. $$F^{\bar \xi }$$-calculus is a fractional local derivative on fractals. It is an algorithm which may be used for computer programs and is more applicable than using measure theory. In this Calculus staircase functions for fractals has important role. $$F^{\bar \xi }$$-fractional differential form is introduced such that it can help us to derive the physical equation. Furthermore, using the $$F^{\bar \xi }$$-fractional differential form of Maxwell’s equations on fractals has been suggested.

Published: March 2013

AbstractAn approach for improving the power generation of a dual-chamber microbial fuel cell by using a nanostructured polyaniline (PANI)-modified glassy carbon anode was investigated. Modification of the glassy carbon anode was achieved by the electrochemical polymerisation of aniline in 1 M H2SO4 solution. The MFC reactor showed power densities of 0.082 mW cm−2 and 0.031 mW cm−2 for the nano- and microstructured PANI anode, respectively. The results from electron microscopy scanning confirmed formation of the nanostructured PANI film on the anode surface and the results from electrochemical experiments confirmed that the electrochemical activity of the anode was significantly enhanced after modification by nanostructured PANI. Electrochemical impedance spectroscopic results proved that the charge transfer would be facilitated after anode modification with nanostructured PANI.
Effect of flow-rate on ethanol separation in membrane distillation process
Authors: Gryta Marek 
Published: March 2013

AbstractThe separation of diluted ethanol solutions and fermentation broths by membrane distillation was investigated. The influence of stream flow-rate on the ethanol flux was studied. An evaluation of the process conditions on the separation degree of ethanol was performed with the application of hydrophobic capillary membranes composed of polypropylene. By removing the alcohol via membrane distillation, it is possible to achieve a higher content of ethanol in the permeate than that in the broth. The enrichment coefficient amounted to 4–6.5, and decreased with an increase of the ethanol concentration in the broth. It was found that the flow-rate affects the value of the enrichment coefficient. A positive influence of carbon dioxide on the ethanol transport through the capillary membrane was observed. The evolution of CO2 bubbles from the broth increases the stream turbulence, probably enhancing the alcohol concentration in the layer adjacent to the membrane surface.

Published: March 2013

Abstract
In this work, the effective diffusion coefficient of boron in the Fe2B phase was evaluated by considering the effect of chemical stresses in the case of paste-boriding of AISI 4140 steel. Two kinetic approaches were proposed to evaluate the diffusion coefficient of boron in the Fe2B phase in the temperature range of 1 123–1 273 K, and considering the effect of the boride incubation times. By applying the mass balance equation at the (Fe2B/substrate) interface and the theory of elasticity, it is possible to determine the effective diffusion coefficient of boron in the Fe2B phase. The obtained value of activation energy of boron diffusion in the presence of chemical stresses was estimated as 158.78 kJ mol−1 using the experimental parabolic growth constants taken from the literature. In addition, the simulated values of effective diffusion coefficients of boron in the Fe2B phase are found to be sensitive to the change in the boriding temperature and to the increase in the upper boron content in the Fe2B phase within its composition range

Abstract
Warpage reduction, dimensional tolerance accomplishment and time and cost saving are some of the most important problems in the injection molding production process. In this study, a real case of a thermoplastic injected part is analyzed. The mold for a pipeline connecting element has been designed, according to known technical and economical criterion to fulfill customer requirements. Particularly for this element, warpage of a specified surface and two diameter sizes are fundamental for correct part functionality and assembling. The analysis is centered on the effects of four process parameters, i. e. packing pressure, packing time, melt temperature and cooling time that heavily influence final results. A finite element model has been used to evaluate their effects on four important final objectives that are the geometrical entities and production cycle time. Each variable has been varied into its proper range, in accordance with a central composite design DoE plan; 25 simulations have been executed and results have been represented using response surfaces. Pareto Front for above listed objectives has been extracted using a genetic algorithm and the best set of parameters has been determined after application of specific selection criteria and a weighted objective function. After numerical evaluation, the CCD DoE plan has been experimentally repeated. Results have been measured on real components, and then represented with response surfaces as well. The same algorithm and objective function have been used for optimization, to determine the experimental optimum parameter set. Finally, the two parameter sets have been compared.

Published: March 2013

We discuss the historic mortality record corresponding to the initial focus of the yellow fever epidemic outbreak registered in Buenos Aires during the year 1871 as compared to simulations of a stochastic population dynamics model. This model incorporates the biology of the urban vector of yellow fever, the mosquito Aedes aegypti, the stages of the disease in the human being as well as the spatial extension of the epidemic outbreak. After introducing the historical context and the restrictions it puts on initial conditions and ecological parameters, we discuss the general features of the simulation and the dependence on initial conditions and available sites for breeding the vector. We discuss the sensitivity, to the free parameters, of statistical estimators such as: final death toll, day of the year when the outbreak reached half the total mortality and the normalized daily mortality, showing some striking regularities. The model is precise and accurate enough to discuss the truthfulness of the presently accepted historic discussions of the epidemic causes, showing that there are more likely scenarios for the historic facts.

Published: March 2013

ABSTRACTIn India, 20 to 40% of all cancer arises in the head and neck region. The highest rate is seen in the eastern and southern regions of our country. The alarming high prevalence of head and neck cancer (HNC) in this region has prompted us to undertake this retrospective study. This study is to give the picture on the prevalence of HNC in the region, as such studies are lacking, till date. This is a 5 years retrospective study of cancer patients from 2007 to 2011 who have been registered in Civil Hospital, Shillong. The period of study is short as registry before 2007 was not properly recorded, but the high prevalence of cancer especially HNC warranted the need to undertake this retrospective study. During the 5-year period, there were a total of 3,123 cancer patients, registered in Civil Hospital, Shillong. In this study, HNC and esophageal cancer constitute 2,207 (70.67%) cases of the total body malignancy (TBM) which is much higher than other studies done in other parts of the country. Fourth decade is the most common age group comprising of 471 cases which accounts for 32.72% of all HNC. This high prevalence of HNC in the young population of the region is alarming and hence needs a comprehensive afford to meet this challenge.This paper, therefore, is an attempt to quantify the spectrum of HNC in the region hoping that this paper will help the health professionals to understand the burden of HNC in the region, so as to generate strategies for future planning.How to cite this articleShunyu NB, Syiemlieh J.

ABSTRACTAimsTo assess preoperative and postoperative shoulder function by electromyography (EMG) in spinal accessory nerve (SAN) sparing neck dissections in head and neck cancers.Materials and methodsA prospective study was done on 50 patients (51 shoulders) with histopathologically proven head and neck cancers with N0 or N1 neck who underwent nerve sparing neck dissections. Patients were assessed preoperatively and postoperatively at 3 weeks and 3 months by needle EMG and muscle strength tests of upper trapezius.Resultsand interpretation: At 3 weeks postoperatively, 11 shoulders (39.3%) in FND group and four shoulders (33.3%) in modified radical neck dissection (MRND) group showed severely abnormal EMG, while in supraomohyoid neck dissection (SOHND) group only two (18.2%) shoulders showed severely abnormal EMG. All patients who underwent nerve sparing neck dissections showed improvement in at least one category on the second electromyogram at 3 months. This could be attributed to neuropraxia or transient devascularization of the accessory nerve. In our study, 11 patients in FND group showed severely abnormal EMG finding, but they did not have as great a degree of shoulder dysfunction as would be expected. This could be due to factors like preoperative condition of other synergistic shoulder girdle muscles, postoperative exercises, etc.ConclusionSAN injuries are common in all types of nerve sparing neck dissections requiring aggressive physiotherapy for an improved shoulder function. To conclude, in patients in whom it is oncologically sound, nerve sparing neck dissections offers significant benefit in terms of shoulder function.How to cite this articleMohiyuddin A, Raj S, Merchant S, Oomen, Kottaram PJ.

ABSTRACTMen with severe infertility suffer a high risk of Y chromosome deletion, hence screening for these cases is recommended prior to treatment with assisted reproduction. Our study aimed to investigate and detect the azoospermia factor (AZF) region deletion, rearrangement and deleted azoospermia (DAZ) gene copy number variations in Egyptian azoospermic infertile men. This was tested on 54 Egyptian nonobstructive azoospermic (NOA) infertile men, with age ranged from 21 to 45 years (mean: 31.4 ± 6.1 years), by STS ± multiplex PCR using a set of 14 sequence tagged sites (STSs) from three different regions of the Y chromosome: AZFa, AZFb, AZFc and sY587/DraI PCRRFLP assay to determine DAZ copy number variations. The results revealed a significant prevalence of AZFc subtypes deletion and reduced DAZ gene dosage in Egyptian azoospermic cases affecting Y chromosome deletions. To our knowledge, this study is the first one to investigate AZFc subtypes deletion and DAZ gene dosage in Egyptian infertile men. We concluded that DAZ genes deletion is a risk factor for spermatogenic damage.How to cite this articleFayez AG, El-Sayed AS, El-Desouky MA, Zarouk WA, Kamel AK, Fahmi IM, El-Ruby MO.

Published: March 2013

Several open surgical techniques have been used to treat recalcitrant cases of snapping iliotibial band with varying results. Recently, endoscopic techniques have become available. The purpose of this study was to investigate the results of a modified endoscopic iliotibial band release using a longitudinal retrospective case series. Fifteen patients (three men and 12 women) with symptomatic external snapping hip were treated with an endoscopic release of the iliotibial band. The average age was 25 years (range 16-37 years). The procedure was performed in the lateral decubitus position using two portals; the iliotibial band was transversally released using a radiofrequency hook probe. The mean follow-up period was 33.8 months (range 12-84 months). The snapping phenomenon was overcome in all the patients. The mean pre-op pain VAS score was 5.5 mm (range 5-7 mm) and the mean post-op pain VAS score was 0.53 mm (range 0-2 mm) with a statistically significant reduction with respect to the pre-operative value (p<0.0001); sixty percent of the patients were pain-free. The mean postoperative Harris Hip Score was 97.5 (range 94-100). No revision procedures were indicated and all the patients returned to their previous level of activity. The mean patient satisfaction score was, on average, 9.3 mm (range 8-10 mm) on the VAS scale. No complications occurred. Endoscopic iliotibial band release is a safe and reproducible technique with excellent results in terms of snapping phenomenon resolution, patient satisfaction, and return to previous level of activity. After strenuous sporting activities 40% of patients complained of very slight pain.

Published: March 2013

Posterior wall fractures are the most common acetabular fractures. Despite being frequently the easiest to treat, posterior acetabular wall reconstruction following such injuries can be challenging. A prospective study was conducted to evaluate the efficacy of a new surgical technique using gluteus medius muscle-pedicled intertrochanteric crest graft for the reconstruction of comminuted posterior acetabular wall fractures where primary comminuted fragments were beyond fixation. This technique has been performed on six patients from 2010 to 2012. The radiologic (Matta score) and clinical evaluation (modified Merle d'Aubigne and Postel score) were recorded at their final follow-up. The mean follow-up was 15.2 months. The radiological outcome by plain radiographs was graded as anatomical in all six patients, the clinical outcome by modified Merle d'Aubigne and Postel score was considered to be excellent in two patients, good in four. Reconstruction of the posterior acetabular wall using gluteus medius muscle-pedicled intertrochanteric crest graft may be appropriate in some instances. The early radiological and clinical results of this new technique were promising.
Are Crutches Required after Hip Arthroscopy? a Case-Control Study
Authors: Jayasekera Narlaka , Aprato Alessandro , Villar Richard N. 
Published: March 2013

Hip arthroscopy provides a less invasive alternative to arthrotomy and has the potential for more rapid rehabilitation. Few guidelines exist for rehabilitation after hip arthroscopic surgery. However, these are not corroborated with evidence of objective outcome measures. In particular, the period for which crutches should be used is imprecisely explained, if explained at all. The purpose of this study was to determine whether or not crutch use is required after hip arthroscopic surgery, and if so, for how long. We compare a postoperative regimen of four weeks partial weight bearing on crutches (Group 1, n = 85) with a regimen that permitted patients to fully weight bear immediately after surgery if comfort allowed (Group 2, n = 80). We used the modified Harris hip score (mHHS) as an outcome measure at six weeks and six months after surgery. For Group 1, the mean duration of crutch use was 28.2 days and the mean postoperative mHHS at six weeks and six months showed significant improvement compared with pre-operatively. For Group 2 the mean duration of crutch use was 13.4 days and the mean postoperative mHHS at six weeks and six months also showed significant improvement compared with pre-operatively. The results demonstrated no significant difference in postoperative mHHS between the two groups at six weeks and six months after surgery. There thus appears to be no need to enforce a defined period of partial weight bearing on crutches after hip arthroscopic surgery, irrespective of the procedure undertaken.
