Osteotome technique: A Minimally Invasive Way to Increase Bone for Dental Implant Placement in The Posterior Maxilla and Prevent Sinus Membrane Perforation for Single and Multiple Teeth Replacements

The posterior maxilla presents with limitations due to the presence of the maxillary sinus as well as overall poor bone quality due to decreased bone density. As a result, procedures such as sinus and ridge augmentations are often required following tooth loss to prepare future implant sites for dental implant placement. The methods that are available for sinus augmentation involve the lateral (direct) approach and the crestal (indirect) approach. While a number of studies find comparable results for bone gain after sinus augmentation, the lateral approach presents with limitations including post op morbidity, and limited access for single tooth areas as well as higher potential of Schneiderian membrane damage. As a result, the crestal approach has been advocated. A number of modifications have been made to the approach to improve its efficacy since it was described by Summers in 1994 and the goal of this article is to review some of these improvements and how they have affected overall success of the technique.
Understanding Why Firms Hold So Much Cash : A Tax Risk Explanation

A recent puzzle in the corporate finance literature is the observation that both multinational and domestic U.S. corporations hold large amounts of cash on their balance sheets. We test whether tax risk is a determinant of cash holdings. Because tax authorities can challenge and disallow tax positions, demanding cash tax payments in the future, firms may hold cash in order to satisfy these potential future demands. We find that both domestic and multinational firms that bear tax risk hold significantly larger cash balances than firms that do not. The data suggest that there is a tax-based precautionary motive to hold cash. This particular type of precautionary motive has not been examined before and adds to both our knowledge of why firms hold so much cash and to our knowledge about the real effects of tax avoidance. *We thank Effrain Benmelech, Nittai Bergman, Amy Dittmar, and David Scharfstein for helpful comments.

The concepts of surveillance and sousveillance: A critical analysis

The concept of surveillance has recently been complemented by the concept of sousveillance. Neither term, however, has been rigorously defined, and it is particularly unclear how to understand and delimit sousveillance. This article sketches a generic definition of surveillance and proceeds to explore various ways in which we might define sousveillance, including power differentials, surreptitiousness, control, reciprocity, and moral valence. It argues that for each of these ways of defining it, sousveillance either fails to be distinct from surveillance or to provide a generally useful concept. As such, the article concludes that academics should avoid the neologism, and simply clarify what sense of surveillance is at stake when necessary.
Clinical outcomes of four liver parenchymal transection techniques for hepatocellular carcinoma : a single institution ’ s experience

Background: To evaluate the safety, efficacy and long-term outcomes of the different techniques of parenchymal transection during liver resections. Methods: We analyze the clinical data of 681 HCC patients who received surgical treatment in West China Hospital from June 2008 to February 2010. Among these patients, 115 cases underwent radical hepatic resection using the Clamp-crush technique, 137 cases using the Water-jet dissection, 249 cases using the Cavitron Ultrasonic Surgical Aspirator (CUSA) and 180 cases using the Harmonic Scalpel. The clinical data including intraoperative parameters, postoperative complications, perioperative morbidity and mortality, hospital stay were collected and analyzed. The overall survival (OS) and recurrence-free survival (RFS) were analyzed using the Kaplan-Meier method and compared the groups via the log-rank test. Results: Clamp-crush group has a minimum of operation time (P=0.001), lowest intraoperative estimate blood loss volume (P=0.045) and shortest length of hospitalization (P=0.004). The 1-, 3-, and 5-year overall survival (OS) rates exhibits no significant difference in clamp-crushing group (70.4%, 53.3% and 43.4%), Harmonic scalpel group (79.8%, 59.9% and 41.9%), Water-jet group (77.2%, 57.3% and 37.8%) and CUSA group (81.5%, 51.9% and 38.5%). The 1-, 3-, and 5-year recurrence-free survival (RFS) rates also exerts no significant difference in Clamp-crushing group (68.9%, 34.6% and 20.7%), Harmonic scalpel group (67.1%, 44.3% and 25.8%), Water-jet group (69.4%, 45.1% and 18.1%) and CUSA group (65.6%, 31.8% and 21.7%). Subgroup analysis also suggested no significant difference in the 1-, 3and 5-year OS or RFS rates. Conclusions: In our study, we believe in that the four techniques for performance of liver parenchymal transection are safe and effective. The Clamp-crush technique should be considered as the first-choice with advantages in less bleeding, short operation time and hospitalization time. And, there is no disadvantageous impact on the OS or RFS for patients with HCC.
Curti Glass Dissolution Parameters : Update for Entsorgungsnachweis

This document provides updated long-term corrosion rates for borosilicate glasses used in Switzerland as a matrix for high-level radioactive waste. The new rates are based on long-term leaching experiments conducted at PSI and are corroborated by recent investigations. The asymptotic rates have been determined through weighted linear regressions of the normalised mass losses, directly calculated from B and Li concentrations in the leaching solutions. Special attention was given to the determination of the analytical uncertainty of the mass losses. The sensitivity of the corrosion rates to analytical uncertainties and to other criteria (e.g. the choice of data points for the regressions) was also studied. A major finding was that the uncertainty of the corrosion rate mainly depends on the uncertainty of the specific glass surface area. The reference rates proposed for safety assessment calculations are 1.5 mg m d for BNFL glasses and 0.2 mg m d for COGEMA glasses. The relevance of the proposed corrosion rates for repository conditions is shown based on the analysis of processes and parameters currently known to affect the long-term kinetics of silicate glasses. Specifically, recent studies indicate that potentially detrimental effects, notably the removal of silica from solution through adsorption on clay minerals, are transitory and will not affect the long-term corrosion rate of the Swiss reference glasses. Iron corrosion products are also known to bind silica, but present data are not sufficient to quantify their influence on the long-term rate.
Impact of an Absorber Ring on Acoustic Damping in Rocket Engine Chambers

A representative combustion chamber-nozzle configuration with perforated inlet and choked outlet is numerically investigated to study the influence of absorber ring location and cavity length on damping of acoustic amplitudes for the first transverse mode under non-reactive ambient temperature conditions. Linearized Euler equations are solved on the basis of a stabilized Finite-Element discretization in order to account for the mean flow effects. The results confirm experimental findings showing a reduction of damping rates for an absorber ring located closely to the inlet, while an absorber ring located closely to the nozzle greatly enhances damping. Furthermore, the reduction of the damping rates in case of an absorber ring located closely to the inlet due to a shielding effect of the transverse mode from the highly dissipative inlet is demonstrated for different cavity lengths and illustrated using numerical field results. Furthermore, the appearance of an additional transverse mode is found, which occurs only in the crosssection of the absorber ring. Finally, it is shown that an absorber ring located at the nozzle effectively enhances damping with a maximum for a cavity length close to the theoretically optimum.

Potential Viroporin Candidates From Pathogenic Viruses Using Bacteria-Based Bioassays

Viroporins are a family of small hydrophobic proteins found in many enveloped viruses that are capable of ion transport. Building upon the ability to inhibit influenza by blocking its archetypical M2 H+ channel, as a family, viroporins may represent a viable target to curb viral infectivity. To this end, using three bacterial assays we analyzed six small hydrophobic proteins from biomedically important viruses as potential viroporin candidates. Our results indicate that Eastern equine encephalitis virus 6k, West Nile virus MgM, Dengue virus 2k, Dengue virus P1, Variola virus gp170, and Variola virus gp151 proteins all exhibit channel activity in the bacterial assays, and as such may be considered viroporin candidates. It is clear that more studies, such as patch clamping, will be needed to characterize the ionic conductivities of these proteins. However, our approach presents a rapid procedure to analyze open reading frames in other viruses, yielding new viroporin candidates for future detailed investigation. Finally, if conductivity is proven vital to their cognate viruses, the bio-assays presented herein afford a simple approach to screen for new channel blockers.
Optimal Monetary Policy Rules and House Prices: The Role of Financial Frictions Alessandro Notarpietro, Bank of Italy

We consider the scope for targeting house prices in simple monetary policy rules using a New Keynesian Dynamic Stochastic General Equilibrium model of the euro area with a housing sector and financial frictions on the household side. If the central bank’s main objective is the minimization of inflation and output fluctuations, then a systematic response to house prices does not entail any systematic sizeable welfare improvement. When the objective of monetary policy is the maximization of aggregate (and individual) welfare, then the optimized rule does feature a systematic reaction to house price variations. The sign and size of such reaction crucially depend on the degree of financial frictions in the economy. If the economy is characterized by both a large share of constrained agents and a high average loan-to-value ratio, then it is optimal to positively react to house price movements. Finally, we show that uncertainty about the actual degree of financial frictions suggests some caution in the construction of optimal monetary policy rules. The welfare costs generated by systematically counteracting house price movements are in general smaller than those implied by a procyclical response. JEL classification: E20; E44; E52.

Serological, clinical, and risk factors of the Newcastle disease on broilers flocks in Algeria

Aim: The work aimed at studying the serological and clinical factors, as well as the risk factors of the Newcastle disease (ND) on broilers herds in Algeria. Materials and Methods: A sample of 1248 birds was randomly selected from 52 broiler flocks. We took blood samples from each bird at the level of the wing vein area where an indirect enzyme-linked immunosorbent assay technique was carried out through the use of an IDvet kit. Results: The flocks showed 82.69% of seroprevalence. Clinically speaking, the most common symptoms were sneezing, rale, greenish diarrhea, torticollis, and motor discords. Most commonly observed postmortem lesions were the proventriculitis, tracheitis, and enteritis. Especially, the caeca are hemorrhagic. The scores show the effect of risk factors. There was a significant effect on the mortality, the hygiene and vaccination groups on antibody titers in time 2. The antibody titers were elevated in the herd that recorded a high mortality (more than 10%) compared with those which recorded a low mortality (<10%) (p=0.002). Therefore, the antibody titers were elevated in herds with bad hygiene, compared with the ones with good hygiene (p=0.04). At last, when broiler chicken were not boosted by ND vaccine, flocks appeared to be more seropositive (p=0.02). Conclusion: The serological survey conducted in this study provided an important scope for ND as a dominant viral disease in broilers. Many factors are responsible for the onset of these diseases; correct biosecurity measures are needed to reduce the impact of this pathology in poultry farms.
AXIAL TENSILE CAPACITY OF HELICAL PILES FROM FIELD TESTS AND NUMERICAL STUDY

Helical piles are used to support structures subjected to axial and lateral loads. The main object of the paper is to study the behavior of helical piles in cohesive and cohesionless soils using a full scale field testing. Then, the field test results are numerically verified using the finite element analysis software ADINA [1]. The tested piles are having two circular pitched bearing plates welded at a spacing of two and half the helix diameter welded to a solid-circular shaft. Field and numerical results showed that the most effective parameters on the helical pile uplift capacity are the embedment depth, soil strength, and number of helix, along with other parameters.
2nd ECATS Conference Preoceedings

The representation of contrail cirrus in climate models has advanced in the last years tremendously. Nevertheless, uncertainties in particular regarding the representation of contrail microphysics still remain. We extend a contrail cirrus scheme within a climate model by implementing a microphysical two-moment scheme to improve the simulation of microphysical properties of contrail cirrus. The global radiative forcing of contrail cirrus estimated for the year 2002 is close to the results of Burkhardt and Kärcher (2011). Although a higher fraction of optical visible contrails are simulated, the larger compensation of longwave and shortwave radiative forcing due to differences in the vertical overlap with natural clouds and a new radiation scheme prevent larger values of radiative forcing. The global radiative forcing of contrail cirrus for the year 2006 is estimated to be 56mW/m2. We also estimate the radiative forcing due to contrail cirrus for several aviation scenarios for the year 2050, considering the increase of air traffic volume, the shift of flight level, the climate change and the reduction of soot emissions.
HeporCloud : An energy , performance and cost efficient resource orchestrator for hybrid heterogeneous cloud computing environments

In major IT companies such as Google, Rackspace and Amazon AWS, virtualisation and containerization technologies are usually used to execute customers’ workloads and applications – as part of their cloud computing services offering. The computational resources are provided through large-scale datacenters, which consume substantial amount of energy and, consequently, affect our environment with global warming. Since long, Google run users’ applications in containers, Rackspace offer bare-metal hardware, whereas AWS run them either in VMs (EC2), containers (ECS) and/or containers inside VMs (Lambda); therefore, ensuring efficient resource management a tedious activity. The role of a resource management system is of the greatest importance, principally, if IT companies practice various kinds of sand-boxing technologies, such as bare-metal, VM and/or containers, in their datacenters (hybrid platforms) to offer quality services to customers. The absence of a single, workload-aware resource manager creates questions on datacenters energy efficiency and performance of the workloads. In most public clouds, resources are idle as peak demand for resources is not regular; therefore, wasting energy, resources and costs. Energy could be saved and performance can be maintained to the expected level through efficient resource management tools. In this paper, we demonstrate the possibility of: (i) using workload-aware resource managers in hybrid clouds; and (ii) achieving energy and cost savings, in heterogeneous hybrid datacenters such that the workload performance is not affected, negatively. Our empirical evaluation suggests that single scheduler is approximately 7.62% more energy and performance efficient than distributed schedulers. Moreover, our proposed resource manager can save approximately 30.47% energy at cost of only 2.14% loss in workload performance.
Concurrent Node Recovery From Failure In Wireless Sensor-Actor Networks

The effectiveness of WSAN deployed in search and rescue, surveillance, battlefield reconnaissance and other applications depends on the inter-node interaction. In sensor networks, sensors collect their information from the physical world and forward their data to actor node then actors collaboratively respond to achieve predefined application missions. The networks can be partitioned into disjoint blocks if an actor suddenly fail and violate such a connectivity goals. The simultaneous node recovery scheme imposes a large node relocation overhead and lot of topology changes and also extent inter-actor data path. Our approach explores the simultaneous node recovery from a multinode failures with maintain nominal topology changes by using the Least Disruptive PILOT Node algorithm. The LDPN algorithm, uses a set of PILOT node that can be used whenever link failures between two sensor node. Inthis approach removes the faulty nodes by using best PILOT nodes and it act as a bridge between the two neighbors of failed nodes. The LDPN algorithms can reestablish the network connectivity and also make sure that the minimal topology changes within the sensor network.
Imagining Transnational Modernity in Contemporary Malaysia : Malay Women , Asian Soap Operas , and Moral Capabilities

This paper is concerned with how urban Malay women negotiate and imagine their modernity as mediated through imported television dramas. It is clear that one of the platforms through which to articulate modernity in contemporary Malaysia is the consumption of popular culture. Promoted at first as an appropriate television genre to strengthen the agenda of Malaysian modernity, Asian soap opera has not been without its tensions. Some authorities have expressed anxiety over what they consider to be the negative influences of foreign issues of morality, which they believe might undermine the standards of Malay womanhood and compromise Malay cultural and national boundaries. Against this perception, however, we propose that urban Malay women negotiate their cultural resources to establish specific watching competencies with which to intelligently and adeptly engage foreign lifestyles in Asian soap operas imported to Malaysia. Watching competencies involve an active mobilization of those resources through which Malay women watch these soaps and measure their adherence to tradition. This paper will focus on how selected urban Malay women exercise their cultural resources, particularly those of adat (the traditional Malay custom as practiced by the Malays in Malaysia) and Islam, to form specific watching competencies for engaging with the depictions of complex inappropriate foreign lifestyles portrayed in Asian soap operas.
Group Sense Making of Multiple Sources in a Hypertext Environment

: Collaboration is important for learning science through inquiry. Hypertext and hypermedia environments are increasingly being used to help support inquiry and enable students to build background conceptual knowledge. Previous research has found that students have difficulty reading multiple texts in groups, so this study explored collaborative discussion of multiple sources in a hypertext system after students read individually. Results indicated that the group that engaged most frequently in monitoring the understanding of group members, evaluating ideas and generating questions to share with the class developed the most sophisticated scientific conceptions. Simply navigating the hypertext system effectively and engaging in elaborated science reasoning was not sufficient for students to develop sophisticated conceptual understandings, reiterating the importance of helping young learners to actively reflect on their understanding and question development during collaboration.
NR 1 H 4 gene single nucleotide polymorphisms are associated with susceptibility to colorectal polyps , ulcerative colitis and colorectal cancer

Background: Down-regulation of farnesoid X Receptor (FXR, NR1H4 gene), a nuclear receptor of bile acids (BA), has been reported in colorectal carcinoma (CRC). FXR may influence BA homeostasis and thus promote CRC, but underlying mechanism remains unknown. The aim of this study was to examine the possible association of single nucleotide polymorphisms in the NR1H4 gene with susceptibility to colorectal polyps, ulcerative colitis (UC) and CRC. Methods: A total of 284 patients (96 CRC, 144 polyps, 44 UC) at Peking Union Medical College Hospital or Henan Cancer Hospital between January and May 2015 were genotyped for five SNP variants of the NR1H4 gene (rs56163822, rs12313471, rs7138843, rs35724, rs10860603) using Sequenom MassARRAY assays. A total of 504 East Asian samples from the NCBI 1000 Genome Project were used as control. Results: In our study rs56163822 allele T and rs7138843 allele A were found to be significantly associated with polyps, UC and CRC. The rs35724 C allele was found significantly associated with polyps and the genotype CC+CG was more frequent in all groups. SNPs rs12313471, rs10860603 were not associated with any of the colorectal pathologies examined. Conclusions: NR1H4 polymorphisms rs56163822 and rs7138843 were associated with susceptibility to polyps, UC and CRC.
Motivations for Tax Compliance: The Case of Small Business Taxpayers in New Zealand

This study investigates small business taxpayers' psychological and social disposition towards taxation based on the motivational postures framework. Our findings show that small business taxpayers can adopt more than one posture towards taxpaying. Sometimes they cooperate and sometimes they defy, depending on the circumstances. In general, the perception of an authority's trustworthiness and fairness helps to close the perceived social distance between taxpayers and the authority. Resistant defiance is about grievance over the way an authority carries out its duties and could be reduced by treating people fairly, fostering trust and improving tax knowledge. Game playing and disengagement postures indicate that people are questioning why an authority exists. This deeper form of defiance is not easily managed. The results support the call for authorities to deal with taxpayers in a fair, respectful and trustworthy manner before deep defiance sets in.
