Published: November 2014

Abstract
Detonation nanodiamonds (ND) present a significant part of nanocarbons group, which could be produced on commercial scale by detonation
of explosives in a closed chamber. Their unique properties of high surface area, low weight and radiation resistance make ND
a prospective candidate for applications in sorption processes in radiochemistry. To study the influence of surface chemistry on
sorption properties, apristine sample of ND was treated with acids and hydrogen. The surface chemistry of the samples was characterised
by infrared spectroscopy, X-ray photoelectron spectroscopy and Boehm titration. The sorption properties of ND were tested fordifferent
radionuclides. The sorption capacity of ND was shown to be higher than those of commonly used radionuclide sorbents like activated
carbon and compariable to other members of nanocarbon group like graphene oxide and carbon nanotubes. The sorption properties were
shown to be influenced by the presence of oxygen-containing groups on the surface of ND. This represents an opportunity to increase the
sorption capacity of ND.

Testing for short-run threshold effects in a vector error-correction framework: a reappraisal of the stability of the US money demand
Authors: Lieb Lenard , Candelon Bertrand 
Published: November 2014

AbstractIn this paper we analyze the stability of the money demand system in the US. To this aim, we develop an estimation and testing framework for a threshold vector error-correction model (VECM), where short-run dynamics are regime dependent and are driven by an exogenous, stationary and ergodic threshold variable. We modify a traditional Wald-type test for linearity and derive its asymptotic distribution, which turns out to be non-standard, but similar to the one proposed by Andrews [Andrews, D. 1993. “Tests for Parameter Instability and Structural Change with Unknown Change Point.”Econometrica61 (4): 821–856]. Accounting for the diversity of the potential determinants of money holdings, a broad scope of money demand systems is analyzed. The linearity test confirms that money demand is not only suffering from structural breaks, but is driven by regimes governed by business cycles. Moreover, a similar pattern and a robust dating of the regimes is observed no matter the money demand system considered, offering hence a reconciling picture of previous empirical studies. From a policy perspective, our findings supports the implementation of cyclical monetary policy by the Federal Reserve.
Moves and steps to sell a paper: a cross-cultural genre analysis of applied linguistics conference abstracts
Authors: Samar Reza Ghafar , Talebzadeh Hossein , Kiany Gholam Reza , Akbari Ramin 
Published: November 2014

AbstractConference abstracts are under-represented promotional texts in spite of their key role in the academic life of and communication among scholars. This generic study attempts to capture the structures and strategies of 160 applied linguistics conference abstracts from four world areas in terms of semantic units of Introduction, Method, and Findings and their Moves and Steps. Results revealed similarities and differences arising mainly from the idiosyncratic nature of genre, place of presentation, and western versus non-western, center versus periphery, and theory- versus application-oriented cultures. Implications for novice and non-native researchers to communicate and submit conference abstracts effectively follow a detailed report.
Balancing multiple roles through consensus: making revisions in haircutting sessions
Authors: Oshima Sae 
Published: November 2014

Abstract
This study demonstrates how participants in haircutting sessions merge different roles during one of the most sensitive moments of an encounter: requesting and/or making revisions to a new cut. During the process of arriving at a consensus of whether or not changes need to be made to the new cut, the stylist and the client negotiate not only the quality of the cut, but also their expected roles. Caring about both the bodies and the minds of customers is an important element in measuring the quality of cosmetological services, a consideration which may oblige stylists to immediately agree with and act upon every client request or concern. However, simply yielding to the customer’s opinions can threaten the stylist’s role as a beauty expert, one who possesses their own professional standards. The analysis reveals that the participants frequently transform revision requests/offers into mutual decisions through a combination of verbal and bodily actions. In doing so, they harmonize the sometimes conflicting responsibilities of “service provider/patron” and “expert/novice.”
Quantification of Anisotropy-Related Uncertainties in Relative Photoluminescence Quantum Yield Measurements of Nanomaterials – Semiconductor Quantum Dots and Rods
Authors: Würth Christian , Geißler Daniel , Resch-Genger Ute 
Published: November 2014

Abstract
In order to assess the anisotropy-related uncertainties of relatively
determined photoluminescence quantum yields (Φ
PL) of
molecular emitters and luminescent nanomaterials, we compared
Φ
PL values measured without and with polarizers using
magic angle conditions and studied systematically the dependence of
the detected emission intensity on the polarizer settings for samples
of varying anisotropy. This includes a dispersion of a spherical
quantum dot (QD) with an ideally isotropic emission, a solution of
a common small organic dye in a fluid solvent as well as dispersions
of elongated quantum dot rods (QDR) with an anisotropic luminescence
and a small organic dye in a rigid polymeric matrix, as ideally
anisotropic emitter. Our results show that for instruments lacking
polarizers, anisotropy-related measurement uncertainties of relative
photoluminescence quantum yields can amount to more than 40%,
with the size of these systematic errors depending on the difference
in emission anisotropy between the sample and the standard.
Physical Modeling on Ground Responses to Tunneling in Sand Considering the Existence of HDPE Pipes
Authors: Wang Fei , Du Yan-Jun , Yang Xiaoming 
Published: November 2014

Abstract
Ground settlement and relevant prediction methods related to underground tunneling have been investigated extensively in previous studies. However, the effects of the existence of service pipelines on the ground movement induced by tunneling have not been well addressed. This study involved a series of physical modeling tests on ground responses to tunneling in sand considering the existence of high-density polyethylene (HDPE) pipes using a custom-made physical modeling system. The system included a model box, a pipe fixing frame, and a number of settlement plates. The developed model box had dimensions of 2.0 m by 2.0 m by 1.5 m, and the bottom of the box consisted of eight movable plates with dimensions of 0.25 m by 2 m by 0.1 m. The plates were lowered down at four levels of maximum vertical distance (10, 20, 30, and 40 mm) to form normal distribution curves, simulating tunneling effects in the sand stratum. Four normal distribution curves were created with maximum lowering distances of the movable plates of 10, 20, 30, and 40 mm to simulate different volumes of ground loss in the tunnel. We performed the four tests one after another by successively lowering down the movable bottom plates. Prior to filling, the required density of backfilled sand was determined using a self-designed instrument. The HDPE pipes, with two diameters (i.e., 300 and 200 mm), were installed in the model box at two different buried depths (i.e., 1.05 and 0.75 m from the spring line of the pipes to the fill surface) using a custom-made fixing frame. The test results demonstrate that the existence of the HDPE pipes resulted in a wider but shallower settlement trough than in the greenfield (without pipe) case. The width of the settlement trough at a given depth decreased with decreasing buried depth of the pipe, whereas it increased with decreasing pipe diameter. The volume of the settlement trough at a given depth was approximately constant, regardless of the existence of pipes, and the vertical displacement of the pipes increased with decreasing diameter and buried depth of the pipe.

Published: November 2014

Abstract
This paper presents an experimental study in which laboratory tests were conducted to investigate how the different interlayers (between the pavement surface slabs and the bases) could improve the performances of vibration response and anti-erosion of the bases. In the tests for vibration response of the bases, geotextile and rubber sheet were used as the interlayers, and the micro-seismic testing system was employed to characterize the vibration response of bases of concrete pavements beneath different interlayers under impact loading. The vibration test results indicated that under the same impact loading, compared with the bases without an interlayer atop, vector sum of the maximum vibration velocity of the bases beneath a rubber sheet interlayer and two layers of geotextile interlayer decreased by 35 % and 80 %, respectively; and vector sum of their maximum vibration displacement decreased by 18 % and 26 %, respectively. In the laboratory tests for anti-erosion, the bases with geotextile or emulsified asphalt slurry seal as the interlayer atop were tested for performances of resisting water erosion via a self-made testing apparatus. The anti-erosion test results indicated that, under the same other conditions, compared with the bases without an interlayer atop, the erosion rate (after 12 min of testing) of the bases with geotextile or emulsified asphalt slurry seal as interlayers atop decreased by 99 % or 59 %, respectively. The interlayer has the effects of damping vibration and resisting water erosion on the pavement base.

ObjectiveIGF1 and IGFBP3 gene polymorphisms have been recently described. However, their potential role in the setting of acromegaly and its outcome is unknown. In this study, we analyze these polymorphisms in patients with acromegaly and investigate their association with clinical presentation and response to treatments.DesignA retrospective observational study was conducted in patients with acromegaly to analyze IGF1 and IGFBP3 gene polymorphisms.MethodsA total of 124 patients with acromegaly (57.3% women, mean age 44.9±13.1 years old) were followed up for a period of 11.4±8.0 years in eight tertiary referral hospitals in Spain. Clinical and analytical data were evaluated at baseline and after treatment. IGF1 and IGFBP3 gene polymorphisms were analyzed using PCR and specific primers.ResultsBaseline laboratory test results were GH 19.3 (8.0–39.6) ng/ml, nadir GH 11.8 (4.1–21.5) ng/ml, and index IGF1 2.65±1.25 upper limit of normal. Regarding the IGF1 gene polymorphism, we did not find any association between the number of cyto-adenosine (CA) repeats and patients’ baseline characteristics. Nevertheless, a trend for higher nadir GH values was observed in patients with <19 CA repeats. Regarding the IGFBP3 polymorphism, the absence of an A allele at the −202 position was associated with a higher baseline IGF1 and a higher prevalence of cancer and polyps. There were no differences in response to therapies according to the specific genotypes.ConclusionsPolymorphisms in the IGF1 and IGFBP3 genes may not be invariably determinant of treatment outcome in acromegalic patients, but they may be associated with higher nadir GH levels or baseline IGF1, and determine a higher rate of colorectal polyps and cancer.

Published: November 2014

BACKGROUND AND OBJECTIVES:
Excessive cardiac monitor alarms lead to desensitization and alarm fatigue. We created and implemented a standardized cardiac monitor care process (CMCP) on a 24-bed pediatric bone marrow transplant unit. The aim of this project was to decrease monitor alarms through the use of team-based standardized care and processes.

METHODS:
Using small tests of change, we developed and implemented a standardized CMCP that included: (1) a process for initial ordering of monitor parameters based on age-appropriate standards; (2) pain-free daily replacement of electrodes; (3) daily individualized assessment of cardiac monitor parameters; and (4) a reliable method for appropriate discontinuation of monitor. The Model for Improvement was used to design, test, and implement changes. The changes that were implemented after testing and adaptation were: family/patient engagement in the CMCP; creation of a monitor care log to address parameters, lead changes, and discontinuation; development of a pain-free process for electrode removal; and customized monitor delay and customized threshold parameters.

RESULTS:
From January to November 2013, percent compliance with each of the 4 components of the CMCP increased. Overall compliance with the CMCP increased from a median of 38% to 95%. During this time, the median number of alarms per patient-day decreased from 180 to 40.

CONCLUSIONS:
Implementation of the standardized CMCP resulted in a significant decrease in cardiac monitor alarms per patient day. We recommend a team-based approach to monitor care, including individualized assessment of monitor parameters, daily lead change, and proper discontinuation of the monitors.
Changes in Child Mortality Over Time Across the Wealth Gradient in Less-Developed Countries
Authors: Bendavid Eran 
Published: November 2014

BACKGROUND:
It is unknown whether inequalities in under-5 mortality by wealth in low- and middle-income countries (LMICs) are growing or declining.

METHODS:
All Demographic and Health Surveys conducted between 2002 and 2012 were used to measure under-5 mortality trends in 3 wealth tertiles. Two approaches were used to estimate changes in under-5 mortality: within-survey changes from all 54 countries, and between-survey changes for 29 countries with repeated survey waves. The principal outcome measures include annual decline in mortality, and the ratio of mortality between the poorest and least-poor wealth tertiles.

RESULTS:
Mortality information in 85 surveys from 929 224 households and 1 267 167 women living in 54 countries was used. In the subset of 29 countries with repeat surveys, mortality declined annually by 4.36, 3.36, and 2.06 deaths per 1000 live births among the poorest, middle, and least-poor tertiles, respectively (P = .031 for difference). The mortality ratio declined from 1.68 to 1.48 during the study period (P = .006 for trend). In the complete set of 85 surveys, the mortality ratio declined in 64 surveys (from 2.11 to 1.55), and increased in 21 surveys (from 1.58 to 1.88). Multivariate analyses suggest that convergence was associated with good governance (P ≤ .03 for 4 governance indicators: government effectiveness, rule of law, regulatory quality, and control of corruption).

CONCLUSIONS:
Overall, under-5 mortality in low- and middle-income countries has decreased faster among the poorest compared with the least poor between 1995 and 2012, but progress in some countries has lagged, especially with poor governance.
Mechanical and Microstructural Properties of Friction Welded AISI 304 Stainless Steel to AISI 1060 Steel AISI 1060
Authors: Ates H. , Kaya N. 
Published: November 2014

Abstract
Rotary Friction welding is one of the most popular methods of joining similar and dissimilar materials. It is widely used with metals and thermoplastics in a wide variety of aviation, transport and aerospace industrial component designs. This study investigates the influence of friction and upsetting pressures on the hardness, tensile properties and microstructure of the welds. The experimental results showed that as the friction and upsetting pressures increased, the hardness and tensile strength values increased, as well. The tensile fracture of welded joint occurred in the AISI 1060 side. The friction processed joints were evaluated for their integrity and quality aspects by optical and scanning electron microscopy. For the perfect interfacial bonding, sufficient upsetting and friction pressures are necessary to reach the optimal temperature and severe plastic deformation to bring these materials within the attraction range.

Published: November 2014

Abstract
In the present investigation, the effects of processing parameters, such as roughing, finishing and coiling temperatures, on the strain hardening exponent and yield strength of a Nb-microalloyed steel has been studied by Taguchi method. In order to achieve maximum n-value and yield strength, tests were done in a laboratorial pilot considering a L16 orthogonal array of Taguchi method under following condition: roughing temperature of 1000, 1050, 1100, 1150 °C, finishing temperature of 800, 850, 900, 950 °C, coiling temperature of 550, 600, 650, 700 °C. Then, analysis of variance and signal to noise ratios are performed on the measured data. The results indicated that the finishing and coiling temperatures were the major factor affecting the mechanical properties. The confirmation tests at optimal conditions approve the effectiveness of this robust design methodology in investigating the hot rolling process of the microalloyed steels.

Published: November 2014

Abstract
The paper presents web base system for an application of parallel object-oriented programming technique in modelling of rolling process of steel plates with semi-solid zone. It also throws light on the problem of semi-solid steels yield stress relationship, one of the main input data of the simulation, and on application of inverse solution, the only possible method of development of the stress-strain curves at extremely high temperatures. Due to limitations of available computer resources a very accurate computation can sometimes be impossible or the time performance can be a barrier for practical application of complex sequential models. Taking advantage of parallel computing the authors have developed an algorithm allowing for fast computation using multiple processors, which is the main subject of the presented paper.

Authors: Winnicki M. , Piwowarczyk T. , Małachowska A. , Ambroziak A. 
Published: November 2014

Abstract
The paper deals with effect of working gas pressure and temperature on surface stereometry of coatings deposited by low-pressure cold spray method. Examinations were focused on aluminium coatings which are commonly used to protect substrate against corrosion. A commercial Al spherical feedstock powder with admixture of Al2O3 (Al + 60vol.-% Al2O3), granulation -50+10 µm, was used to coat steel, grade S235JR. Thedeposited coatings were studied to determine their stereometry, i.e. roughness, transverse and longitudinal waviness, topography of surface and thickness as the functions of gas pressure and temperature. A profilometer and focal microscope were used to evaluate the stereometric properties. In order to reduce the number of variables, the remaining process parameters, i.e. shape and size of de Laval nozzle, nozzle-to-substrate distance, powder mass flow rate, linear velocity of spraying gun, were kept unchanged. The investigation confirmed influence of temperature and pressure on coating thickness as well as on the surface seterometry.

Authors: Hadryś D. , Węgrzyn T. , Piwnik J. 
Published: November 2014

Abstract
Micro-jet welding is an innovative method of weld forced cooling immediately after welding. It allows to obtain weld with superior properties in comparison to conventional welding. The reason for this is to obtain a more favorable structure of the weld metal deposit (WMD) with much higher amount of acicular ferrite (AF). Different structures and mechanical properties of weld metal deposit were obtained by using various gases for cooling. The paper shows the relationship between the type of gas for micro-jet cooling and plastic properties of the weld joint. Coefficient of restitution and plastic strain were selected to describe changes of weld plastic properties for different micro-jet cooling gases. The tests were performed in dynamic conditions (impact).

Published: November 2014

Abstract
The article concerns the issues of flotation process effectiveness in relationship to the operating conditions of a high-pressure comminution process course. Experimental programme covering a flotation laboratory batch tests was a verification technique of a high-pressure crushing operations course. The most favorable values of flotation concentrate weight recoveries were obtained for the pressing force 6 kN and 4% of the feed moisture. It was also determined the model of the concentrate weight recovery as a function of pressing force in the press and feed moisture content. This model was the basis for the optimization of effects of copper ore flotation processes preceded in high-pressure crushing operation in roller presses.
