Published: June 2015

ABSTRACTThe role of ferroelectric LiNbO3 (LNB) in altering the frequency dependence of the capacitance of CaCu3Ti4O12 (CCTO) thin films has been investigated. A cost effective spin coating deposition process was used to integrate the oxide heterostructures onto silicon substrates. This study showed that the frequency stability of the CCTO/LNB structure was much improved when the crystallization conditions and physical dimension of each layer were optimized. To integrate this structure with current silicon technology, heterostructures of CCTO and LNB thin films were fabricated on HF terminated Si using chemical solution deposition. It was found that the order of deposition of the two layers was important for the structural quality of the heterostructures with the CCTO layer followed by the LNB layer being the preferred structure. In addition to improvement of the capacitance variation with frequency, the heterostructures also provide a path to tuning the frequency of operation.

Published: June 2015

Abstract
We experienced a case of life-threatening hypotension and bronchoconstriction associated with edema in a patient undergoing resection of a tumor of the right mandible following intravenous midazolam for induction of general anesthesia. We decided to postpone surgery for further examination of a possible drug-induced allergic reaction, and we rescheduled surgery for 1 week later. After administering H1 and H2 histamine antagonists, we administered a slow induction with sevoflurane in nitrous oxide and oxygen plus intravenous atropine sulfate after performing a test dose injection. We safely induced and maintained anesthesia with nitrous oxide, oxygen, and sevoflurane.
Inadvertent Endobronchial Intubation in a Patient With a Short Neck Length
Authors: Cornelius Bryant , Sakai Tetsuro 
Published: June 2015

Abstract
Inadvertent placement of the endotracheal tube into the right bronchus during intubation for general anesthesia is a fairly common occurrence. Many precautions should be taken by the anesthesia provider in order to minimize the incidence of endobronchial intubation, including bilateral auscultation of the lungs, use of the 21/23 rule, and palpation of the inflated endotracheal cuff at the sternal notch. These provisions, however, are not foolproof; anesthesia providers should realize that endobronchial intubation may occur from time to time because of variations in patient anatomy, changes in patient positioning, and cephalad pressures exerted during surgery. A 58-year-old man with chronic obstructive pulmonary disease received general endotracheal anesthesia for a laparoscopic cholecystectomy. His height was 165 cm (5 ft, 5 in) and the endotracheal tube was secured at his incisors at 21 cm after placement with a rigid laryngoscope. Bilateral breath sounds were confirmed with auscultation, although they were distant because of his chronic obstructive pulmonary disease. After radiographic examination in the postanesthesia care unit, a right main-stem intubation was revealed to have taken place, resulting in complete atelectasis of the left lung. After repositioning of the endotracheal tube, radiography confirmed that the patient had an anatomically short tracheal length.

Abstract
The aim of this study was to investigate the effect of changes in end-tidal carbon dioxide tension (ETCO2) during remifentanil (Remi) infusion on oral tissue blood flow in rabbits. Eight male tracheotomized Japan White rabbits were anesthetized with sevoflurane under mechanical ventilation. The infusion rate of Remi was 0.4 μg/kg/min. Carbon dioxide was added to the inspired gas to change the inspired CO2 tension to prevent changes in the ventilating condition. Observed variables were systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), common carotid artery blood flow (CCBF), tongue mucosal blood flow (TBF), mandibular bone marrow tissue blood flow (BBF), masseter muscle tissue blood flow (MBF), upper alveolar tissue blood flow (UBF), and lower alveolar tissue blood flow (LBF). The CCBF, TBF, BBF, UBF, and LBF values were increased, while MBF was decreased, under hypercapnia, and vice versa. The BBF, UBF, and LBF values were increased, while the MBF value was decreased, under hypercapnia during Remi infusion, and vice versa. The BBF, MBF, UBF, and LBF values, but not the CCBF and TBF values, changed along with ETCO2 changes during Remi infusion.

The study evaluated the farmers participatory methods of upscaling technologies for increasing mungbean production in the south-western region of Bangladesh. It was a descriptive survey study and data were collected by interviewing 120 sample farmers in DFID-Mungbean Project areas in Bangladesh. The participatory methods trailed in the project were farmers seed exchange program, demonstrations trials, agricultural training and workshops on mungbean production. However, farmers to farmers seed exchange program was identified as the most effective method. During the project phase, the farmers selected and adopted their preferred mungbean varieties, developed and practiced appropriate land preparation techniques along with improved post-harvest operations. Farmers participation in technology generation and upscaling resulted in increasing area and production of the mungbean many fold during 2004 to 2008. The average yield of mungbean was 1370 kg/ha and almost all framers obtained yields more than that of the national average of 705 kg/ha. Agricultural training, farm size and extension contact accounted for 83% of the total variation in upscaling technology and 90% of the variation in yield of mungbean. The extent of upscaling technology in terms of increase in area and yield of mungbean were associated with various participatory methods practiced by the farmers in the study area.

The main focus of the study was to determine the food security status of the women involved in food for work program in terms of access to food (meals/day/person) and intake of energy (kilo calorie) and to explore the relationship between some selected characteristics of the beneficiaries with the changes in food security. The study was conducted in Kapasia upazila of Gazipur district during July 2013 to September 2013. Data were collected through pre-tested interview schedule. One hundred and ten women were selected following simple random sampling method. All of the family members of the respondents used to take three-meals/day when Food for Work Program (FFW) program was ongoing. More than four-fifth (84.55%) of the household members received optimum to above optimum kcal/day when FFW was running, but only three-fifth (60.90%) of the respondents family members took optimum to above optimum kcal/day when FFW program did not run. Optimum level and above optimum level calorie in taking family members increased by 12.73 percent and 10.91 percent, respectively when FFW program was running. The difference between per capita calorie intake by the respondents and their family members when FFW program was and was not running was found significant. Correlation analyses showed that annual income and credit facility had positive and significant relationship with contribution of FFW program on changes in food security status of the beneficiaries.

Published: June 2015

The long term behaviour of ultimate industrial waste was modellid by considering a “source term” made of stabilized waste, and a “transfer compartment” consists of a clay layer acting as a passive barrier between the waste and the aquifer underlying the disposal site. The possible pollutant release from the stabilized waste is accounted for via the diffusion of non-sorbeb species, so as chloride ions. The transfert of these pollutants throught the clay barrier is the result of the complete set up transport mechanisms through porous media, i.e. convection, diffusion and dispersion. Ion-exchange phenomena inside the clay barrier are also taken into account by instantaneous reversible adsorption mechanism. The first results of this modelling work highlights the respective influences of the waste stabilization, the disposal lay-out, the geochemical interaction phenomena within the clay barrier, and the properties of the underlying aquifer. Furthermore, this first set of calculations about no-retarded species (chloride ions) show that it should be possible, in all cases, to select appropriate combinations for the “stabilized waste + active barriers +passive barriers” system so that safety criteria (such as drinking water quality standards for the aquifer underlying the disposal site) can be met at any time.
Le comportement à long terme des stockages de résidus industriels ultimes fait l'objet de travaux de modélisation incluant un terme source, constitué par des produits stabilisés et un terme transfert, constitué par une barrière argileuse servant d'écran passif entre les déchets et un aquifère circulant sous le stockage. Les éventuelles émissions provenant du déchet stabilisé sont représentées par une diffusion d'ions non retardés tels que les ions chlorures. Les transports de polluants, au travers de la barrière cumulent l'ensemble des moteurs du transport en milieux poreux à savoir, la convection, la diffusion et la dispersion. Les mécanismes d'échanges d'ions sont également pris en compte sous forme d'adsorption instantanée et réversible. Les premiers résultats de simulation mettent en évidence l'influence propre de la stabilisation, du mode de stockage, des phénomènes d'interactions géochimiques de la barrière argileuse et de la qualité de l'aquifère sous-jacent. De plus, ces premiers calculs sur des espèces non retardées (de type chlorure) montrent qu'il devrait être toujours possible de trouver une ou plusieurs combinaisons du système « déchet stabilisé-barrières actives-barrières passives » telles que les critères de sûreté soient constamment vérifiés (potabilité des eaux des aquifères sous-jacents par exemple).

Published: June 2015

lncineration of industrial wastes produces slags which, according to the future French regulations, will require to be stabilized prior to disposal. Portions of heavy metals contained in slags could indeed be solubilized and therefore constitute a toxic mobile fraction which has to be eliminated. Tredi-ASH is a chemical leaching process (exchange reaction with CaCI2, obtained from wet gas cleaning neutralization) used to extract mobile metal pollutants from slags. This process allows to detoxify and to stabilize an important fraction of slag's original weight (70 to 95% dry weight), reducing ultimate waste volume without transfer of pollution. Sludges generated by stirring and leaching (5 to 30% dry weight) can be recycled on waste incineration plants, to neutralize acid waters originating from wet gas cleaning.
La législation relative à la mise en décharge des mâchefers d'incinération de déchets industriels imposera dans un avenir proche la stabilisation de ces résidus comme préalable au stockage. Le procédé Tredi-ASH transforme par lixiviation chimique une fraction pondérale importante des scories traitées en résidus stables (70 à 95 % du poids sec). Les matières en suspension générées par le brassage mécanique (5 à 30 % du poids sec initial) sont séparées par filtration et peuvent être recyclées sur les unités d'incinération, en pré-neutralisation des eaux acides issues du lavage des fumées. Les métaux toxiques extraits dans les lixiviats sont traités par biosorption microbienne. Cette seconde partie du procédé fera l'objet d'un prochain article.

Published: June 2015

The commercial extraction of metals from ores by microbial leaching turns to account the iron oxidation capabilities of Thiobacillus ferrooxidans. The iron oxidation involves an electron transfer chain localized in the periplasmic space of the cell. The characterization of the redox proteins involved the determination of their physiological role, together with genetic engineering programs, could have implications to increase the leaching capacity of these bacteria.
L'extraction industrielle de métaux à partir de minerais par biolixiviation met à profit la faculté d'oxyder le fer de Thiobacillus ferrooxidans. L'oxydation du fer fait intervenir une chaîne de transfert d'électrons localisée dans le périplasme de la cellule. La caractérisation des protéines d'oxydoréduction impliquées, la détermination de leur rôle physiologique et les techniques du génie génétique pourront permettre d'améliorer le processus de biolixiviation.

Faut-il encore avoir peur de nos déchets ménagers ? Un risque redoutable : la dispersion incontrôlée
Authors: Tillier Claude 
Published: June 2015

With real examples in a french department it is seen that household refuse and other similar refuses are not so ordinary that it can be thought. Their scattering dilutes discharges, but often goes with no treatment and then increases health and environment risks. This scattering concerns as much products as refuses which follows from them.
Par des exemples concrets sur un département, on voit que les déchets ménagers et assimilés ne sont pas aussi banals qu'on pourrait le penser. Leur dispersion dilue les rejets, mais s'accompagne souvent d'une absence de traitement et accroît alors les risques pour la santé et l'environnement. Cette dispersion concerne autant les produits d'origine que les déchets qui en découlent.
Déchets de chantier de bâtiment. Les actions de la Fédération nationale du bâtiment

Published: June 2015

For our modern society, waste management becomes more and more a priority. Meanwhile, the legal framework is old: law of July 15, 1975 - anybody producing or keeping waste (...) has to manage the waste disposal. In a first step, the public Authorities action was oriented towards domestic waste disposal and in a second time aimed to dangerous waste of the industrial activities. Due to their own specificity, construction and demolition waste (about 25 millions tuns a year) couldn’t take place among the above categories, leaving alone the building firms: closing down of the dumping waste, difficulties to find places to get rid of and as well, growth of elimination costs reaching about 1 to 6% of the turnover construction. ln this downward trend, building contractors and their professional Organization are involved to set up a management in order to eliminate construction and demolition waste at the best price.
La gestion des déchets, de leur production à leur élimination, est devenue pour nos sociétés modernes une préoccupation majeure. La réglementation relative à l'élimination des déchets est cependant ancienne : la loi du 15 juillet 1975 stipulait « toute personne qui produit ou détient des déchets (...) est tenue d'en assurer ou d'en faire assurer l'élimination ». L'action des pouvoirs publics s'est orientée dans un premier temps vers l'élimination des déchets des ménages, puis vers celle des déchets dangereux de l'industrie. De par leur spécificité, les déchets de chantier du bâtiment, évalués à 25 millions de tonnes par an, ne s'inscrivant dans aucune de ces catégories ont été trop souvent oubliés, mettant les entreprises de bâtiment dans des situations inconfortables : fermeture de décharges communales, problèmes pour trouver des lieux d'élimination, mais aussi et surtout risques d'augmentation importante des coûts d'élimination pouvant atteindre 1 à 6 % du chiffre d'affaires selon les professions. Dans ce contexte défavorable, les professionnels du bâtiment et leur organisation se mobilisent pour permettre la réalisation de structures de gestion afin d'éliminer les déchets du bâtiment à un coût optimisé.
