Toulouse face à la Garonne: emprise de l'urbanisation dans la plaine inondable et geohistoire des amenagements fluviaux
Authors: Valette Philippe , Carozza Jean Michel 
Published: September 2017

The city of Toulouse in France settled on the banks of the Garonne.The evolution of the urbanization of the city reflects the ambivalent relationship with the river: scourge to fight against dams which is landscape,but also sought to resource which is created mills, ports ... The historical geography of river developments facing urbanization reveals the development and juxtaposition of artifacts on the river. Urban river landscapes Toulouse are the result of a slow time construction. The objective of this work is to define these different temporalities that produced the current river landscapes. These are the subject of development projects and their implementation will change the looks by putting the Garonne in the center and heart of the city.
Vertical Strain-rate Measurements in an Arctic Ice Cap and deductions from them
Authors: Paterson W. S. B. 
Published: September 2017

AbstractClosely spaced measurements of diameter of thermally drilled bore holes reveal a pattern of small variations. These patterns serve to igerntify points on the bore-hole wall; thus the change in length of sections of bore hole can be gertermined as a function of time. This method has been used to measure vertical strain-rate as a function of gerpth in two bore holes near the crest of the Devon Island ice cap. The measured strain-rate, corrected for firn compaction, varies significantly with gerpth. The vertical component of velocity at the surface was gertermined freom the contraction rate of a bore hole that penetrated to the base of the ice. Comparison of this velocity with the present accumulation rate suggests that the ice cap, in the vicinity of the bore hole, is thickening slightly at present. The age of the ice at various gerpths, as calculated freom the measured vertical velocities, is in broad agreement with radio-carbon dates covering the past 6 000 years. This suggests that the flow of the ice cap has not varied significantly over this period, and thus that the present accumulation rate, which is causing thickening, is slightly above the average for the period.
A Correction Factor for Rogh's Stability Index of Slab Avalanche Release
Authors: Sommerfeld R. A. , King R. M. , Budding F. 
Published: September 2017

AbstractRoch (1966) proposed that the ratio of the strength of a bed layer to the load on it could be used to predict slab avalanche release. However, both he and Perla (unpublished) found that the mean strength was approximately twice the mean stress for snow layers known to have failed. A strength-size relationship is proposed to explain this discrepancy.
Assessing knee strength ratios and bilateral deficit via dynamic vs. static tests in amateur rugby union players
Authors: Dobbs Ian J. , Watkins Casey M. , Barillas Saldiam R. , Wong Megan A. , Brown Lee E. 
Published: September 2017

BACKGROUND: Assessing players’ leg strength ratios prior to season is important in order to measure performance and identify weaknesses. Leg ratios are calculated by dividing the moment of hamstring by quadriceps. The simple (concentric only) HQ ratio and the dynamic control ratio (DCR) (Hamstring eccentric/Quadriceps concentric) are used to detect asymmetry, knee strength, and bilateral deficit (BD). However, open (OKC) and closed kinetic chain (CKC) tests potentially provide different information regarding muscle strength and balance. OBJECTIVE: The purpose of this study was to measure the abovementioned ratios in male and female amateur rugby union players and to assess difference between OKC and CKC tests. METHODS: Six males (age [Formula: see text] 22.00 [Formula: see text] 2.61 y, height [Formula: see text] 172.67 [Formula: see text] 6.12 cm, mass [Formula: see text] 80.28 [Formula: see text] 11.13 kg) and 11 females (age [Formula: see text] 24.73 [Formula: see text] 3.66, height [Formula: see text] 164.00 [Formula: see text] 5.23, mass [Formula: see text] 74.00 [Formula: see text] 18.14 kg) rugby union players performed an isometric-mid thigh pull (IMTP) and isokinetic knee extension/flexion at 60[Formula: see text]/s. RESULTS: The non-dominant leg simple ratio (0.81 [Formula: see text] 0.13%) was greater than dominant (0.74 [Formula: see text] 0.14%) while the DCR (0.81 [Formula: see text] 0.14%) was greater than simple ratio (0.73 [Formula: see text] 0.10%). The OKC BD ([Formula: see text]21.00 [Formula: see text] 13.86%) was significantly greater than its CKC counterpart ([Formula: see text]6.76 [Formula: see text] 9.79%) while males’ OKC BD ([Formula: see text]30.55 [Formula: see text] 14.93%) was significantly greater than females’ ([Formula: see text]15.79 [Formula: see text] 10.55%). CONCLUSION: The DCR may be more sport specific when measuring knee strength, while an OKC test is more likely to detect BD due to muscle isolation.
PET Imaging of Tau Pathology and Relationship to Amyloid, Longitudinal MRI, and Cognitive Change in Down Syndrome: Results from the Down Syndrome Biomarker Initiative (DSBI)

Published: September 2017

Background: Adults with Down syndrome (DS) represent an enriched population for the development of Alzheimer’s disease (AD), which could aid the study of therapeutic interventions, and in turn, could benefit from discoveries made in other AD populations. Objectives: 1) Understand the relationship between tau pathology and age, amyloid deposition, neurodegeneration (MRI and FDG PET), and cognitive and functional performance; 2) detect and differentiate AD-specific changes from DS-specific brain changes in longitudinal MRI. Methods: Twelve non-demented adults, ages 30 to 60, with DS were enrolled in the Down Syndrome Biomarker Initiative (DSBI), a 3-year, observational, cohort study to demonstrate the feasibility of conducting AD intervention/prevention trials in adults with DS. We collected imaging data with 18F-AV-1451 tau PET, AV-45 amyloid PET, FDG PET, and volumetric MRI, as well as cognitive and functional measures and additional laboratory measures. Results: All amyloid negative subjects imaged were tau-negative. Among the amyloid positive subjects, three had tau in regions associated with Braak stage VI, two at stage V, and one at stage II. Amyloid and tau burden correlated with age. The MRI analysis produced two distinct volumetric patterns. The first differentiated DS from normal (NL) and AD, did not correlate with age or amyloid, and was longitudinally stable. The second pattern reflected AD-like atrophy and differentiated NL from AD. Tau PET and MRI atrophy correlated with several cognitive and functional measures. Conclusions: Tau accumulation is associated with amyloid positivity and age, as well as with progressive neurodegeneration measurable using FDG and MRI. Tau correlates with cognitive decline, as do AD-specific hypometabolism and atrophy.

Double Interatrial Septum appearing as an Atrial Myxoma: A Case Report and Review of the Literature
Authors: Wyrobek Julie , Chales H Brown IV , Kostibas Megan P , Mayer Susan A , Cameron Duke E , Hayanga Heather K 
Published: September 2017

ABSTRACT
A double interatrial septum (DIS) is a rare finding during echocardiographic evaluation and can often be mistaken for other more common atrial anomalies. The interatrial cavity created by the septum creates a low-flow state that increases risk of thrombus formation and thromboembolic events. Transesophageal echocardiography (TEE) plays a vital role in accurate diagnosis as a DIS is often not seen during transthoracic echocardiography (TTE). In this case, we report a patient who presented for surgery with a preoperative diagnosis of an atrial myxoma, was instead discovered to have a DIS, and then subsequently underwent DIS resection without complication. We discuss the differential of a DIS, including an atrial septal pouch, cor triatriatum, atrial myxoma, and aneurysmal interatrial septum and the classic features of each anomaly for appropriate diagnosis and management.

New Intracardiac Mass in Right Atrium Postcardiac Surgery: Thrombus or Artifact?
Authors: Choudhary Minati , Aggarwal Shivani , Bhoje Amolkumar 
Published: September 2017

ABSTRACT
Intracardiac masses namely thrombus, vegetation, and tumors may have overlapping echocardiographic appearance. Differentiating them from artifacts and normal anatomic structures further adds to the confusion. We report a similar scenario about the appearance of a new hyperechoic mass in the right atrium (RA) after mitral valve replacement (MVR) surgery.

Role of Perioperative Echocardiography in the Diagnosis of Hypertrophic Cardiomyopathy: Decoding Special Problem in the Background of Commoners
Authors: Mandal Banashree , Ghotra Gurpinder S 
Published: September 2017

ABSTRACT
We present a case posted for CABG with double valve replacement (DVR) for triple-vessel coronary artery disease (CAD), rheumatic severe mitral regurgitation, and severe aortic stenosis. However, preprocedure echocardiography in the operation theater confirmed the diagnosis of hypertrophic obstructive cardiomyopathy (HOCM) instead of valvular aortic stenosis, thereby altering the procedure performed to CABG, mitral valve replacement (MVR), and myectomy.

Modification in Surgical Plan following Intraoperative Detection of Co-existent Right Atrial Thrombus by Transesophageal Echocardiography in Chronic Constrictive Pericarditis
Authors: Mahajan Sachin , Ganesan Rajarajan 
Published: September 2017

ABSTRACT

Introduction
Chronic constrictive pericarditis (CCP) is common in developing countries, tuberculosis being the most common cause. Dyspnea and congestive symptoms are the most common nonspecific presenting symptoms that require further evaluation for clinching the diagnosis. Coexistent right atrial (RA) thrombus and CCP are rare occurrences. Preoperative detection of RA thrombus is very important to avoid the risk of pulmonary thromboembolism during pericardiectomy or cannulation for establishing cardiopulmonary bypass (CPB). Perioperative echocardiography may play a crucial role in this setting. We report a case of CCP in which preoperative transesophageal echocardiography (TEE) detected RA thrombus that led to change in surgical plan and provided continuous monitoring during surgery.

Case Report
A 14-year-old male presented with a history of abdominal distension and pedal edema for 5 months. Physical examination revealed raised jugular venous pulse with normal heart sounds and no murmurs. Transthoracic echocardiography (TTE) revealed constrictive physiology and thickened pericardium. After induction of anesthesia, TEE revealed an irregular hyperechoic mass (50 × 36 × 30 mm) in the RA free wall that was not detected on preoperative TTE and computerized tomography (CT). Thickened pericardium all around mandated limited pericardiectomy under TEE guidance to allow bicaval cannulation for establishing CPB. This was followed by surgical removal of the thrombus and remaining pericardiectomy using CPB. His postoperative period was uneventful and the patient was discharged home on postoperative day 7.

Conclusion
The TEE may be instrumental in diagnosis of coexistent RA thrombus in the case of CCP resulting in major change in surgical plan and providing perioperative monitoring to avert significant morbidity and mortality.

A Novel Approach for the Closure of Multiple Diastema: A Clinical Technique
Authors: Karale Rupali , Jha Shirin , Aswathanarayana Srirekha , Santhosh Lekha , Kapadia Megha 
Published: September 2017

ABSTRACT
Correction of multiple diastema without much preparation of the teeth is one of the challenges in clinical esthetic dentistry. Indirect restorative procedures render excellent esthetics; however, these are invasive procedures that lead to the removal of unnecessary tooth structure in order to achieve the desired result. Whenever possible, the most conservative approach is preferred over the invasive procedures. Many innovative techniques have been advocated, varying from restorative procedures, frenectomy, or orthodontic treatment for the closure of spaces in between the anterior teeth. When a relatively smaller diastema is present in between the teeth, extensive preparation of the tooth structure is not necessary and utilization of free hand bonding of composite resin may yield the desired result. So far, innumerable cases have been reported in the literature which has illustrated various techniques for closure of diastema. The following case report discusses a novel technique for closure of multiple diastema.

Conservative Management of Traumatic Tooth Fracture by Fracture Fragment Reattachment and Single Visit Nonsurgical Endodontic Treatment
Authors: Mazumdar Paromita 
Published: September 2017

ABSTRACT
Anterior crown fractures are common form of traumatic dental injuries that mainly affect the maxillary anterior teeth in children, teenagers as well as adult population. A trauma with accompanying fracture of anterior teeth is an agonizing experience for an individual requiring immediate attention, not only because of the physical disfigurement but also because of the psychological impact on the patient. Over time numerous techniques and materials have evolved for the restoration of the injured teeth, such as, resin composite with or without pin, orthodontic bands, resin crown, and ceramic crowns. Reattachment of fractured tooth fragments can provide good and long-lasting esthetics and function. Patient cooperation and understanding of the limitations of the treatment is important for good prognosis. This article reports management of complicated coronal tooth fracture treated by reattachment on tooth fragments on the palatal aspect and single visit nonsurgical endodontic treatment.

“ENDOCROWN”—An Effective Viable Esthetic Option for Expurgated Endodontically treated Teeth: Two Case Reports
Authors: Vinola Selvanathan MJ , Balasubramanian Saravanakarthikeyan , Mahalaxmi Sekar 
Published: September 2017

ABSTRACT
Endocrowns are a viable option for the restoration of extensively damaged endodontically treated posterior teeth. The main objective is to achieve a bonded biomimetic reconstruction, i.e., minimally invasive of root canals. The clinical procedure that involves the endocrown fabrication may be considered less complex, more practical, and easier to perform when compared with that of conventional crowns with post and core. This article highlights two different case reports of badly mutilated endodontically treated teeth, effectively managed by means of endocrown-type restorations fabricated with both metal-free and metal ceramic-based prostheses with a 6-month follow-up period.

An Empirical Study of Information and Communication Technology for Empowerment of Rural Women in Ghana
Authors: Kwapong O. Adwoa Tiwaah Frimpong 
Published: September 2017

There is a relationship between ICTs and empowerment of rural women. ICTs are applicable to all sectors of development for women, most especially education, livelihoods, healthcare and government which are directly linked to poverty alleviation. Meanwhile there are arguments that tight fiscal constraints facing Ghana may frustrate the widespread use of ICT by households. This is especially troublesome in the case of poor rural female households because without some type of government assistance, the ICT revolution may escape them altogether. Most scholars and policy leaders recognize that ICT is one of the contributing factors to social and economic disparities across different social and economic groups, for example, disparities between developed and developing countries, between rural and urban dwellers, and between men and women. The critical information needed for making appropriate and relevant ICT policies to improve rural conditions for women is to identify the characteristics of rural female households, and how these characteristics influence the choice of ICT technology.
The study uses results from a survey of 1000 households from the ten regions in Ghana to assess rural female household heads’ willingness to pay for alternative ICT use in the delivery of information to them. A pooled cross section technique was used to estimate an aggregate technology choice function for the entire country. Among the principal factors in the empirical model were households’ incomes, levels of education, sizes of households, availability of cooperatives or community organizations, age, and marital status. Standard regression techniques that correct for possible heteroscedastic errors due to the differences in regional and households’ attributes were used to estimate the model.
The results of the study leads to a need to set rural empowerment policies and programs within the broader poverty reduction policies of the government and also within the attainment of the Millennium Development Goals (MDGs). The results enforce that the attainment of the MDGs would boost ICT use in delivering information to rural households since income was found to be consistently statistically significant in explaining rural women’s willingness to pay for information. Considering the context of the relationship between incomes and ICT use to empower rural women the key issue is for policy and program planners to better understand the dynamics in the enterprises of rural women and to recognize shifts in economic activity that may be counter to the historical pattern of economic activity which is agriculture oriented and design programs that will respond adequately to such shifts. By so doing rural women will be in a good position to utilize the full potential of ICT which will in turn improve their productivity/income and facilitate their empowerment
Open Access to Resource Management in Multimedia Networks
Authors: Pencheva Evelina Nikolova , Atanasov Ivaylo Ivanov 
Published: September 2017

The paper is dedicated to mechanisms for open
access to resource management in the Internet Protocol (IP)
multimedia networks. First we present the concept of IP
Multimedia Subsystem (IMS) and explain the IMS functional
architecture, principles of quality of service management and
service control in IMS. Then we describe the idea behind the
opening of network interfaces for third parties so that others
besides the network operator can create and deploy services.
Open Service Access (OSA) and Parlay appear to be the
technologies for value-added service delivery in multimedia
networks. In the paper we take a closer look to the
Parlay/OSA interfaces that allow third party applications to
access the resource management functions in IMS. OSA
"Connectivity Manager" interfaces and OSA "Policy
Management" interfaces are considered. Parlay X Web
Services interfaces provide a higher level of abstraction than
Parlay/OSA interfaces and gain an amazing amount of
support among service developers. We address "Applicationdriven Quality of Service" Parlay X Web Service and
"Policy" Parlay X Web Service also.
Layered Mobility Model Architecture - LEMMA
Authors: Pelov Alexander P , Noel Thomas 
Published: September 2017

This paper presents the
generic layered architecture for mobility
models (LEMMA), which can be used to
construct a wide variety of mobility
models, including the majority of models
used in wireless network simulations. The
fundamental components of the
architecture are described and analyzed,
in addition to its benefits. One of the core
principles stipulates that each mobility
model is divided in five distinct layers that
communicate via interfaces. This allows
their easy replacement and
recombination, which we support by
reviewing 19 layers that can form 480
different mobility models. Some of the
advanced features provided by the
architecture are also discussed, such as
layer aggregation, and creation of hybrid
and group mobility models. Finally, some
of the numerous existing studies of the
different layers are presented.
A Pedagogy for Integrating a Value Congruence and Ethics Connection into Course Work: The Nine Dots Exercise
Authors: Weinstein Dianne 
Published: September 2017

Value congruence, i.e., the agreement between personal and organizational values, may be viewed as the foundation for one’s ethical well-being on-the-job. Yet, the linkage between value congruence and ethics is not soundly addressed in college classrooms. This article describes the pedagogy used to successfully incorporate the value congruence-ethics connection into course work. The author first provides a theoretical introduction as a backdrop for developing the pedagogy including research on value congruence and ethics, the rationale for strengthening the role of “values” in ethics education, and the teaching strategy applied. Thereafter, the author describes steps to teach value congruence and ethics, including learning objectives and an instructional model. The learning objectives and instructional model can be modified to apply within ethics training programs in the workplace.
