Published: November 2013

Abstract
To maintain the integrity of the Vasa warship after salvage in 1961, conservation treatment with polyethylene glycol was carried out to prevent the collapse of cell walls. This treatment had negative effects on the strength and stiffness of the oak and the hull structure has been found to slowly deform over time. It is of interest to construct a three-dimensional numerical computer model to model and predict the deformation of the warship. This creates difficulties related to the complexity of measuring the detailed material properties that are required as input. In this context, a non-destructive methodology to predict the stiffness of the Vasa oak in terms of moduli of elasticity in the three principal directions of timber at critical positions in the ship would be useful. The twofold aim of the paper is to propose a strategy for a support system and to conduct an on-site assessment of the warship to predict the mechanical properties of the Vasa oak material. This paper also contains an up-to-date review of all essential mechanical data measured on the Vasa oak. The preliminary investigation using an X-ray technique to investigate the density properties produced promising results for future use in the evaluation of the mechanical performance. Based on these results, a procedure to establish the stiffness properties of the Vasa oak in terms of MOE was suggested, using a combination of data from previous measurements, in combination with extended tests on Vasa oak specimens and an X-ray-based density calibration procedure. The general complexity of the Vasa warship can be mainly attributed to large variations in the properties of Vasa oak due to surface degradation, chemical treatment and the disintegration of the cell-wall structure originating from centuries of waterlogged conditions. That causes difficulties when assessing mechanical and physical properties on a structural level. A combination of visual inspection together with X-ray investigation is of great importance to evaluate those properties and to obtain more accurate estimates. The results from evaluating mechanical properties can serve as input in a numerical model and serve as a foundation for decision-making relating to the modification of the support system.

Purpose To compare the diagnostic characteristics of two geriatric screening tools (G8 and Flemish version of the Triage Risk Screening Tool [fTRST]) to identify patients with a geriatric risk profile and to evaluate their prognostic value for functional decline and overall survival (OS). Patients and Methods Patients ≥ 70 years old with a malignant tumor were included if a new cancer event occurred requiring treatment decision. Geriatric screening with G8 and fTRST (cutoff ≥ 1 [fTRST (1)] and ≥ 2 [fTRST (2)] evaluated) was performed in all patients, as well as a geriatric assessment (GA) evaluating social situation, functionality (activities of daily living [ADL] + instrumental activities of daily living [IADL]), cognition, depression, and nutrition. Functionality was re-evaluated 2 to 3 months after cancer treatment decision, and death rate was followed. Functional decline and OS were evaluated in relation to normal versus abnormal score on both screening tools. Results Nine hundred thirty-seven patients were included (October 2009 to July 2011). G8 and fTRST (1) showed high sensitivity (86.5% to 91.3%) and moderate negative predictive value (61.3% to 63.4%) to detect patients with a geriatric risk profile. G8 and fTRST (1) were strongly prognostic for functional decline on ADL and IADL, and G8, fTRST (1), and fTRST (2) were prognostic for OS (all P < .001). G8 had the strongest prognostic value for OS (hazard ratio for G8 normal v abnormal, 0.38; 95% CI, 0.27 to 0.52). Conclusion Both geriatric screening tools, G8 and fTRST, are simple and useful instruments in older patients with cancer for identifying patients with a geriatric risk profile and have a strong prognostic value for functional decline and OS.

Purpose To determine whether a nurse navigator intervention improves quality of life and patient experience with care for people recently given a diagnosis of breast, colorectal, or lung cancer. Patients and Methods Adults with recently diagnosed primary breast, colorectal, or lung cancer (n = 251) received either enhanced usual care (n = 118) or nurse navigator support for 4 months (n = 133) in a two-group cluster randomized, controlled trial with primary care physicians as the units of randomization. Patient-reported measures included the Functional Assessment of Cancer Therapy–General (FACT-G) Quality of Life scale, three subscales of the Patient Assessment of Chronic Illness Care (PACIC), and selected subscales from a cancer adaptation of the Picker Institute's patient experience survey. Self-report measures were collected at baseline, 4 months, and 12 months. Automated administrative data were used to assess time to treatment and total health care costs. Results There were no significant differences between groups in FACT-G scores. Nurse navigator patients reported significantly higher scores on the PACIC and reported significantly fewer problems with care, especially psychosocial care, care coordination, and information, as measured by the Picker instrument. Cumulative costs after diagnosis did not differ significantly between groups, but lung cancer costs were $6,852 less among nurse navigator patients. Conclusion Compared with enhanced usual care, nurse navigator support for patients with cancer early in their course improves patient experience and reduces problems in care, but did not differentially affect quality of life.

Abstract
The self assembly behavior of 2,4-dihydroxyazobenzene (DHAB) and 4-hydroxyazobenzene (HAB) inclusion complexes were studied by SEM and TEM. Formation of inclusion complexes were characterized by FT-IR, DSC, PXRD, 1H NMR, UV–visible, fluorescence, time-resolved fluorescence, and molecular modeling techniques. Micrometer-sized rods were observed in DHAB:α-cyclodextrin (α-CD) and DHAB:β-cyclodextrin (β-CD) inclusion complexes while microsheets were obtained in HAB/α-CD and HAB/β-CD complexes. In DHAB/CD and HAB/CD individual “barrel” type (head to head arrangement) of 2:2 inclusion complexes form microrods and microsheets through intermolecular hydrogen bonding between the neighboring complexes. Molecular modeling calculations suggest that (i) DHAB and HAB form stable complexes with α-CD and β-CD, (ii) intermolecular hydrogen bonds form between the guests and CDs. Investigations of energetic, thermodynamic, and electronic properties by PM3 method confirmed the stability of the inclusion complex.

AbstractThe following article examines concrete examples of naturally occurring humor and laughter taken from simulated Japanese negotiations. Task-oriented negotiations were held in group settings, and participants were assigned conflicting interests to observe the occurrence of laughter in conflict situations. In-depth analyses of several negotiations are conducted in an attempt to reveal how humor and laughter are used to affect the negotiation process, and to shed light on how Japanese negotiators perceive and manage conflict situations. The current study reveals that Japanese conversations are governed by a concept known as
Utilization of Coal Deposits of Thar Colliers with Underground Coal Gasification, Opportunities and Challenges in Syngas Generation

ABSTRACT
Pakistan owns about 180 billion tons of coal buried under its surface. However, the share of the coal for power generation is just 2.25%, while oil has 58.5%. This conflicting policy of relying on imported and expensive oil is increasing budget deficit and disturbing the country economy. We studied different energy resources in detail and found that the coal deposits of Thar, approximate reserves of 175 billion tons can be an excellent energy source for the country to meet and fulfill the energy demand.
This research shows detail analyses; chemical processes, reactions, and well linking techniques used for underground coal gasification. This study also demonstrates different operational problems and their solutions mainly water flux and weak strata along the coals seams. At block-V Thar Coal, one gasifier with 36 wells has been successfully completed and a test burn was carried. To link the wells for underground coal gasification, we investigated different techniques such as directional drilling, hydraulic fracturing, and reverse combustion linking. Thus we used reverse combustion linking because of its low cost and effectiveness to link the wells. So the syngas was successfully produced from the coal reserves of Thar by underground coal gasification. This produced low cost syngas after processing can be used for fertilizer industry, gas supply, power generation, diesel production, chemicals manufacturing, and in paint industry.

Abstract
Mostly the wildcat wells are dry and extravagant, hence requires an ultimate solution during exploration. In order to overcome this issue, micro-hole drilling technology is highly result oriented technique these days. In this technique, the drilling holes with diameter ranges between 1.36" to 2.00" inches achieve the depth of 700ft using coiled tubing, drilling rig unit and micro-hole instruments.
This paper covers the definitive elucidation to make the whole process leaving less environmental foot prints and hit the depth upto 5000ft economically. This could be achieved by introducing micro sized casings by means of micro instrumentation and coiled tubing unit along with the provision of low cost, exploratory wells in reducing material, intensive labor and supporting equipments.
An integrated digital model of well bore has been developed using drilling calculator using the parameters of Sindh province lithology. The results were analyzed to investigate the influence of this technology, by comparing cost and depth graphs. It is elucidated that this technique is more environmental friendly and promising in terms of minimum cost of exploration.
Evaluating Hydraulic Fracture Properties Using Well Test Analysis on Multi Fractured Horizontal Wells
Authors: Imam Kamran 
Published: November 2013

Abstract
Drilling horizontal wells is a standard practice in the oil industry. Placing hydraulic fractures along the horizontal section of the well, to increase hydrocarbon production, is also rapidly gaining popularity, especially as more tight formations, even shale, are targeted. Understanding the behaviour of each individual fracture requires production logging. This results in additional cost and also puts the well under "operational risks".
It is desirable to use pressure data to understand the well behaviour, as this is readily available due to modern completions usually having permanent pressure gauges installed. Also, pressure data can be obtained without putting well at any "operational risks". In the region around fractured horizontal well, multiple flow regimes occur simultaneously. In pressure transient data usually a combination of all the flow regimes is observed making characterisation of the reservoir difficult.
In this paper, a comparison of the existing analytical approaches is made to analyse pressure transient data for a horizontal well intercepted by multiple fractures. Using the analytical solutions of the diffusivity equation presented by different authors for a multiply fractured horizontal well, the dimensions of Stimulated Reservoir Volume (SRV) are calculated. Also, the number of active fractures and the flow rate from each fracture are determined using the pressure data. The time for the start of interference is calculated and the time dependence of individual fracture flow rates is also estimated. An observation about the inability to find the orientation of fractures is also made.
Staged Subtalar Fusion for Severe Calcaneus Fractures with Bone Loss
Authors: Williams Chad G. , Coffey Michael J. , Shorten Peter , Lyions James D. , Laughlin Richard T. 
Published: November 2013

Background:
With high energy fractures to the calcaneus there is the potential for significant bone loss. The loss of bone can make it difficult to fully regain calcaneal alignment. In addition these fractures are often associated with significant soft tissue injury. These two factors make it difficult to address this injury in a single stage, and can have significant complications. To address these issues our initial goal in treatment has been restoration of calcaneal alignment and stabilization of the surrounding soft tissue, followed by delayed/staged subtalar arthrodesis.

Methods:
Patients with calcaneus fractures treated by a single surgeon from 2002 to 2012 were reviewed. Injuries which were found to have medial extrusion of the posterior facet and bone loss, and subsequently underwent a staged protocol involving early provisional fixation and late subtalar fusion were included.

Results:
We treated 6 calcaneus fractures with bone loss. All patients were treated with staged subtalar fusion after initial irrigation and debridement and provisional fixation. No soft-tissue complications were noted after the fusion procedure in any of the six cases. Fusion occurred in all six patients at an average of 20.6 weeks (range, 13-23 weeks). All patients were able to ambulate and wear a regular shoe by one year following the initial injury.

Conclusion:
It is important in the high energy calcaneus fracture to assess for both soft tissue integrity and bone loss. A thorough debridement of both the soft tissues and any devitalized bone should be performed as well as provisional fixation which attempts to restore near normal calcaneal anatomy. Definitive fusion should not be performed until the soft tissues have fully recovered.

Abstract
We have investigated oxygen decorating in the (10, 0) aluminum nitride nanotube (AlNNT) by density functional theory. Band gaps, total (TDOS) and partial (PDOS) densities of state and chemical-shielding isotropic (CSI) and chemical-shielding anisotropic (CSA) have been calculated or determined in three models of the investigated (10, 0) AlNNT: pristine (model.0), O-decorating at the one ring in the middle of AlNNT (Model.1) and O-decorating at the nitrogen mouth of AlNNT (Model.2). The results indicated that the dipole moment does not detect the significant effects of dopant whereas TDOS, PDOS and band gap energies detect notable effects. The CSI and CSA values for the Al and N atoms-contributed to the Al-O bonds or those atoms close to the decorated region, in both models of O-decorated AlNNTs are changed.

Abstract
Modified compositions in the system V2O5/(NH4)2Mo2O7 have been prepared by means of mechanochemical, hydrothermal, microwave and ultrasonic treatments in aqueous medium. Chemical and phase transformations occurring on the stages of modification and following calcinations have been studied with the help of XRD, DTA-TG, FTIR and UV-Vis spectroscopy, nitrogen adsorption, and SEM. It has been established that precursors of catalytically active phases possessing meso-macroporous structure have been formed during modification. The comparison of the properties of compositions prepared via different methods has been carried out. Particularly, precursors modified via various procedures possess different morphology.

Published: November 2013

Sharing parenting activities : a few years on… and hardly any change.
The division of parenting duties with regard to child care and education lies at the heart of the debates on equality between men and women and the transmission of gendered behaviour. The Survey on family and intergenerational relationships conducted in two waves (in 2005 and 2008) by the French National Institute for Demographic Studies is used to analyse the involvement of mothers and fathers according to the type of task performed (getting the children dressed, helping with their homework, taking them to school, putting them to bed, organising their leisure) as well as how this has changed in recent years. To begin with, the comparative analysis of the two periods makes it possible to draw an overview of the changing patterns of involvement among fathers and mothers, notably via a follow-up of parenting couples throughout the period. Secondly, the reasons for these changes are examined. Women’s gainful employment and its transformations across time appear to be paramount in redefining the division of parenting duties. However, this redefinition is also the outcome of other socio-demographic characteristics pertaining to the family and to the couple.
« Dis maman, comment on fait les garçons ? »
Authors: Sauvêtre Julie 
Published: November 2013

Dans la société actuelle, nous sommes amenés à recevoir en consultation de plus en plus de familles de configurations variées : familles nucléaires, séparées, recomposées, monoparentales, homoparentales... au sein desquelles chaque membre, parent, enfant, doit trouver sa place. Dans chacune de ces familles se pose souvent la question de l’articulation entre la conjugalité et la parentalité, ce qui vient mettre au travail la question des origines, prégnante dans le développement de l’enfant. Au travers d’un cas clinique retraçant l’histoire d’un petit garçon de 5 ans et de sa maman homosexuelle, nous verrons comment il peut être difficile pour le parent d’aborder une conjugalité complexe dans l’histoire de l’enfant et comment, lorsque cette question des origines reste confuse, peuvent s’instaurer des difficultés de construction identitaire chez l’enfant.
Des usages de l'Antiquité dans l'histoire
Authors: Hartog François 
Published: November 2013

Le passé antique a souvent participé à la définition d’identités nationales ou politiques. Ainsi, l’Allemagne du xix e siècle fait de la Grèce son modèle, et de la philologie sa discipline reine. En France, c’est l’héritage latin qui prédomine, et l’on cherche chez les « classiques » une vérité et une beauté immuables. La Grèce archaïque, elle, émerge à une époque où vacille la confiance dans le régime moderne d’historicité.

Rapport au savoir, besoin de croire et illusions de certitudes
Authors: Hatchuel Françoise 
Published: November 2013

À travers une analyse des ancrages psychiques de la croyance et de la quête de savoir, l’article montre comment la croyance, première, est ce qui ancre l’enfant dans son sentiment d’exister, et comment son « écroulement » va déclencher la quête de savoir. La notion de « points de certitude symboliques » (Piera Aulagnier), c’est-à-dire d’éléments certains parce que garantis comme tels par la société, permet ensuite de regarder comment, dans les sociétés dites « traditionnelles », l’insertion des sujets est fiabilisée par le collectif, à travers notamment l’institution de la filiation et le passage ritualisé à l’âge adulte, alors que dans nos sociétés hypermodernes, la perte de cette garantie pousse le sujet à une recherche de « preuves » à réitérer en permanence. L’illusion scientiste ainsi entretenue entraîne une fragilisation des sujets et un renforcement des risques d’emprise.
Subordination croyante et autonomie du sujet chez les entrepreneurs et dirigeants chrétiens
Authors: de Brémond d’Ars Nicolas 
Published: November 2013

À partir de la figure de l’adhérent au mouvement français des Entrepreneurs et dirigeants chrétiens ( edc ), l’article pose la question du conflit potentiel de souveraineté entre le domaine religieux et le domaine économique. D’une part, l’individu croyant que la vocation d’entrepreneur pousse à l’autonomie de décision ; d’autre part le fidèle censé suivre les enseignements doctrinaux (et éthiques) de l’organisation religieuse. Subordination et autonomie sont l’enjeu du débat. À partir du milieu des années 1980, les edc élaborent une pratique du témoignage qui distend les contraintes et ouvre un espace de conciliation. L’entrepreneur chrétien est invité à construire un récit-de-soi qui se projette sur l’horizon d’attente de l’ensemble des croyants. Ainsi, l’économique et ses contraintes relèvent du maintenant, tandis que le croire se positionne comme chemin vers l’horizon. Double allégeance et conflit éthique sont désamorcés par le recours à la temporalité de l’expérience. La subordination disparaît.
