A heterojunction structure of semiconductor material, for a high electron mobility transistor includes a substrate, a buffer layer, arranged on the substrate, of a large bandgap semiconductor material, based on a nitride from column III, where the buffer layer is not intentionally doped with n-type carriers, a barrier layer arranged above the buffer layer, of a large bandgap semiconductor material based on a nitride from column III, where the width of the bandgap of the barrier layer is less than the width of the bandgap of the buffer layer. The heterojunction structure additionally comprises an intentionally doped area, of a material based on a nitride from column III identical to the material of the buffer layer, in a plane parallel to the plane of the substrate and a predefined thickness along a direction orthogonal to the plane of the substrate, where the area is comprised in the buffer layer.

This paper presents a probabilistic approach for the analysis and design of a strip footing subjected to an inclined load. Both the punching and sliding modes of failure were considered. The deterministic model of the soil punching mode was based on the kinematic approach of limit analysis using a non-symmetrical translational multiblock failure mechanism. The vertical and horizontal components of the footing load were considered as random variables. The soil shear strength parameters were first modelled as random variables and then as random fields to take into account the soil spatial variability. Spatial averaging was used to transform the random field problem to a simple problem of correlated random variables. The reliability index of each failure mode and the system failure probability were calculated. When the soil shear strength parameters were modelled as random variables, it was shown that the coefficient of variation of the angle of internal friction and that of the horizontal footing load have a non-negligible effect on the system failure probability. On the other hand, when the shear strength parameters were modelled as random fields, it was found that the case of (a) a finite (i.e. noninfinite) autocorrelation distance and/or (b) an anisotropic soil regarding the autocorrelation distance, leads to a greater reliability of the foundation with respect to the reference case of isotropic and infinite autocorrelation distances (i.e. the case of random variables). For both cases of random variables or random fields, it was shown that the negative correlation between the shear strength parameters gives a greater reliability of the foundation in comparison to the uncorrelated shear strength parameters. Finally, for design, an iterative procedure was performed to determine the breadth of the footing for a target system failure probability.

Under line Pathology of Materials; one of the environmental causes of damage effects on concrete is freeze thaw cycles, which deteriorate the concrete exposed to water in cold weather. An example of old concrete is a dam project that was built in Canada, in the early 1909-1913. This project was reconstructed in 1932, 1934 and 1972, and required renovation due to the ice abrasion with the freeze/thaw cycles. Before completing any renovation, it is required to analyze the structural stability and the concrete failures of this dam. An investigation was conducted to determine the quality of the concrete in the Piers and in the Bridge Deck Slab. It was also required to determine the basic materials' properties that constitute this project. This will improve the analysis of its stability [10]. Core samples were examined and used as test samples, for the Alkali-Silica reactivity test samples, as well as the compressive strength test, the Chloride Ion test, and the freeze thaw testing which was performed on two sets of 12 concrete core samples that were taken from different locations in the project. These locations are the representations of the age of the concrete. Thus, the age difference between the samples' two sets is four decades. Testing was performed on prisms cut from cores. ASTM C-666 procedure (A) was applied using an automatic test system [6]. It was suggested that a plan for renovation of this project should be performed after the analysis is undertaken to assess the conditions estimating the remaining life of the concrete in this project [15]. © 2014 Elsevier B.V.

Medication prescribing errors are made all over the world. However, exact data about them are lacking in Lebanon. Our objective was to describe medication errors, including drug-drug interactions in medication orders given to patients admitted to Lebanese hospitals. A prospective study was carried out on 313 patients taken from seven Lebanese hospitals; 1826 medication orders were assessed for errors and 456 drug-drug interactions were found. Data was entered and analyzed on SPSS. Around 40% of medication orders were judged to comprise at least one prescribing error, mainly no ordering of parameters monitoring (20%), unnecessary medication (9%), and no indication (7%). Errors occurred mainly in the pediatrics (50%) and internal medicine wards (40%). Having an infectious or gastrointestinal problem almost doubled the risk of medication prescribing error. Antiulcer agents, NSAIDs, antibiotics and steroidal agents were the medications mainly involved. Meanwhile, 12 adverse medication events were reported, with an odds ratio of association to a medication error of 7.4 (p = 0.004). As for drug-drug interaction (DDI), prescriptions comprised zero to 29 interactions, involving medications with low margin of safety such as acenocoumarol, amiodarone and valproate. Pharmacodynamic interactions were mainly found (60%). The majority of DDI were of high clinical significance and well documented (80%), with moderate (59%) to major (17%) severity. These results highlight the urgency of an intervention to improve patients' outcomes and avoid deleterious impact of inadequate medication use in Lebanon. The presence of a clinical pharmacist, the inclusion of computerized systems and the application of drug management policies are suggested to decrease medication prescribing errors and enhance the physician attention to DDI.

Gastric sleeve gastrectomy has become a frequent bariatric procedure. Its apparent simplicity hides a number of serious, sometimes fatal, complications. This is more important in the absence of an internationally adopted algorithm for the management of the leaks complicating this operation. The debates exist even regarding the definition of a leak, with several classification systems that can be used to predict the cause of the leak, and also to determine the treatment plan. Causes of leak are classified as mechanical, technical and ischemic causes. After defining the possible causes, authors went into suggesting a number of preventive measures to decrease the leak rate, including gentle handling of tissues, staple line reinforcement, larger bougie size and routine use of methylene blue test per operatively. In our review, we noticed that the most important clinical sign or symptom in patients with gastric leaks are fever and tachycardia, which mandate the use of an abdominal computed tomography, associated with an upper gastrointrstinal series and/or gastroscopy if no leak was detected. After diagnosis, the management of leak depends mainly on the clinical condition of the patient and the onset time of leak. It varies between prompt surgical intervention in unstable patients and conservative management in stable ones in whom leaks present lately. The management options include also endoscopic interventions with closure techniques or more commonly exclusion techniques with an endoprosthesis. The aim of this review was to highlight the causes and thus the prevention modalities and find a standardized algorithm to deal with gastric leaks post sleeve gastrectomy. © 2014 Baishideng Publishing Group Inc.

The sustainable access to basic sanitation services is one of the targets of the Millennium Development Goals (MDGs) adopted by the United Nations in 2000. A monitoring and reporting program on progress made on access to improved sanitation services has been pursued by the global community using the universal indicator 'proportion of population using an improved sanitation facility'. However, monitoring and reporting progress using this indicator does not reflect the effective wastewater management and pollution control. This paper presents a methodological approach for quantitative assessment of the effective wastewater management based on non-additive aggregation methodology which accounts for the interactions among indicators. Firstly, a set of indicators are identified and calculation methods are presented. Secondly, the use of 2-order Choquet integral to aggregate indicators into an Effective Wastewater Management index (EWM) is proposed. At the practical level, results of evaluation of the EWM of the Wastewater Collection Systems in Lebanon are then presented and discussed. Finally, the conclusions and further developments are presented. © 2014 Springer International Publishing Switzerland.

The CN violet system (B2Σ+ - X 2Σ+) molecular emission spectrum is frequently observed in plasma sources containing hydrocarbons and nitrogen mixture. We have simulated the spectrum of (0,0) and (1,1) bands of this system for different rotational and vibrational temperatures. The influence of the noise to signal ratio has been studied, if the noise to signal ratio is about 10% we found an error of 6% at temperature 3000K and 10% at 6000K.

Classic calculations of the magnetic moments μp and μn of the nucleons using the traditional exponential kernel show instability with respect to variations of the Borel mass as well as arbitrariness with respect to the choice of the onset of perturbative QCD. The use of a polynomial kernel, the coefficients of which are determined by the masses of the nucleon resonances stabilizes the calculation and provides much better damping of the unknown contribution of the nucleon continuum. The method is also applied to the evaluation of the coupling gA of proton to the axial current and to the strong part of the neutron-proton mass difference δMnp. All these quantities depend sensitively on the value of the 4-quark condensate (0qqqq0), and the value (0qqqq0)≃1.6(0qq0)2 reproduces the experimental results. © 2016 American Physical Society.
