Rational Design of Peptide-Functionalized Surface Plasmon Resonance Sensor for Specific Detection of TNT Explosive
Authors: Wang Jin , Muto Masaki , Yatabe Rui , Onodera Takeshi , Tanaka Masayoshi , Okochi Mina , Toko Kiyoshi
Published: October 2017

In this study, a rationally-designed 2,4,6-trinitrotoluene (TNT) binding peptide derived from an amino acid sequence of the complementarity-determining region (CDR) of an anti-TNT monoclonal antibody was used for TNT detection based on a maleimide-functionalized surface plasmon resonance (SPR) sensor. By antigen-docking simulation and screening, the TNT binding candidate peptides were obtained as TNTHCDR1 derived from the heavy chain of CDR1, TNTHCDR2 derived from CDR2, and TNTHCDR3 from CDR3 of an anti-TNT antibody. The binding events between candidate peptides and TNT were evaluated using the SPR sensor by direct determination based on the 3-aminopropyltriethoxysilane (APTES) surface. The TNT binding peptide was directly immobilized on the maleimide-functionalized sensor chip surface from N-γ-maleimidobutyryl-oxysuccinimide ester (GMBS). The results demonstrated that peptide TNTHCDR3 was identified and selected as a TNT binding peptide among the other two candidate peptides. Five kinds of TNT analogues were also investigated to testify the selectivity of TNT binding peptide TNTHCDR3. Furthermore, the results indicated that the APTES-GMBS-based SPR sensor chip procedure featured a great potential application for the direct detection of TNT.
Experimental and Numerical Investigations in Shallow Cut Grinding by Workpiece Integrated Infrared Thermopile Array
Authors: Reimers Marcel , Lang Walter , Dumstorff Gerrit
Published: October 2017

The purpose of our study is to investigate the heat distribution and the occurring temperatures during grinding. Therefore, we did both experimental and numerical investigations. In the first part, we present the integration of an infrared thermopile array in a steel workpiece. Experiments are done by acquiring data from the thermopile array during grinding of a groove in a workpiece made of steel. In the second part, we present numerical investigations in the grinding process to further understand the thermal characteristic during grinding. Finally, we conclude our work. Increasing the feed speed leads to two things: higher heat flux densities in the workpiece and higher temperature gradients in the material.
A Novel Position Compensation Scheme for Cable-Pulley Mechanisms Used in Laparoscopic Surgical Robots
Authors: Liang Yunlei , Du Zhijiang , Wang Weidong , Sun Lining
Published: October 2017

The tendon driven mechanism using a cable and pulley to transmit power is adopted by many surgical robots. However, backlash hysteresis objectively exists in cable-pulley mechanisms, and this nonlinear problem is a great challenge in precise position control during the surgical procedure. Previous studies mainly focused on the transmission characteristics of the cable-driven system and constructed transmission models under particular assumptions to solve nonlinear problems. However, these approaches are limited because the modeling process is complex and the transmission models lack general applicability. This paper presents a novel position compensation control scheme to reduce the impact of backlash hysteresis on the positioning accuracy of surgical robots’ end-effectors. In this paper, a position compensation scheme using a support vector machine based on feedforward control is presented to reduce the position tracking error. To validate the proposed approach, experimental validations are conducted on our cable-pulley system and comparative experiments are carried out. The results show remarkable improvements in the performance of reducing the positioning error for the use of the proposed scheme.

Authors: Lester Diarmuid , McGrane Bronagh , Belton Sarahjane , Duncan Michael , Chambers Fiona , O’Brien Wesley
Published: October 2017

(1) Background: Research has shown that post-primary Irish youth are insufficiently active and fail to reach a level of proficiency across basic movement skills. The purpose of the current research was to gather cross-sectional baseline data on Irish adolescent youth, specifically the prevalence of movement skills and patterns, in order to generate an overall perspective of movement within the first three years (Junior Certificate level) of post-primary education. (2) Methods: Data were collected on adolescents (N = 181; mean age: 14.42 ± 0.98 years), attending two, mixed-gender schools. Data collection included 10 fundamental movement skills (FMS) and the seven tests within the Functional Movement Screen (FMS™). The data set was analysed using the Statistical Package for Social Sciences (SPSS) version 20.0 for Windows. (3) Results: Overall, levels of actual mastery within fundamental and functional movement were low. There were statistically significant age-related differences observed, with a progressive decline as age increased in both the object control (p = 0.002) FMS sub-domain, and the in-line lunge (p = 0.048) test of the FMS™. (4) Conclusion: In summary, we found emerging evidence that school year group is significantly associated with mastery of movement skills and patterns. Results from the current study suggest that developing a specifically tailored movement-oriented intervention would be a strategic step towards improving the low levels of adolescent fundamental and functional movement proficiency.
Long-Term Sustainability from the Perspective of Cullet Recycling in the Container Glass Industry: Evidence from Italy
Authors: Testa Mario , Malandrino Ornella , Sessa Maria , Supino Stefania , Sica Daniela
Published: October 2017

Glass manufacturing is a high-volume process, during which large substance quantities are transformed into commercial products, and significant amounts of non-renewable resources and energy (i.e., thermal fuels and electrical power) are consumed. The main purpose of this study is to give a critical explanation of the performance of the Italian container glass industry from the perspective of cullet being recycled, to outline the opportunities for transition towards circular business models that stimulate innovation in new sectors based on reverse-cycle activities for recycling. In 2015, disparate performances have been achieved as regards the container glass recycling rate in northern, central, and southern Italy, accounting for around 73%, 64%, and 55%, respectively. In fact, only northern Italy is in line with European targets, as by 2025 it will only need to increase its current performance by two percentage points, unlike central and southern Italy that will have to increase performance by, respectively, 11% and 20%. This shows a need to improve the efficiency of municipal waste collection systems in central and southern Italy, where undifferentiated waste still holds appreciable amounts of glass. Consequently, we propose several improvement channels, from the revision of waste legislation to the re-engineering of waste management supply chains.
Built Environment, Travel Attitudes and Travel Behaviour: Quasi-Longitudinal Analysis of Links in the Case of Greeks Relocating from US to Greece
Authors: Milakis Dimitris , Efthymiou Dimitrios , Antoniou Constantinos
Published: October 2017

In this study, the possible causal links between the built environment, travel attitudes and travel behaviour of people that have moved between totally different urban and transportation contexts were investigated. A quasi-longitudinal design was developed to collect data about the perceived neighbourhood characteristics, neighbourhood preferences, travel attitudes and changes in car, walking and bicycle usage of 51 Greeks who relocated from the US to Greece. Variable reduction techniques were applied prior to developing our models because of the small sample size. The results of this study offer support for a causal relationship between the built environment and travel behaviour identified in the existing literature. For instance, longer travel time to city center was associated with higher car use, higher density neighbourhoods and increased accessibility to local amenities were associated with increased bike use and better access to a district shopping center was associated with more walking after relocation. Our results also showed that in contexts like Greece, where transport infrastructures are not adequately developed, lack of safe bike conditions and easy access to public transportation are important determinants of bicycle use and walking. Thus, according to our results, promoting sustainable mobility in contexts like Greece would require not only enhancing accessibility through relocation of activities, but also by improving infrastructures for public transport, bicycle and walking.
Bonus Point System for Refuse Classification and Sustainable Development: A Study in China
Authors: Guo Shijie , Ding Guomin , Zhao Qian , Jiang Meini
Published: October 2017

The rapid growth of household waste not only endangers the environment and people’s health, but also limits social and economic development. The effective sorting and recycling of garbage can control this problem. Adopting a semi-quantitative case study method, our researchers investigated the effect of a bonus point system for refuse classification that improves the accuracy of refuse classification and the residents’ environment awareness. In the system, residents will receive some gifts after sorting the garbage correctly. We also investigated the attitudes of residents and companies towards this novel system. Our researchers employed various methods to analyze garbage-sorting data, questionnaires completed by residents, and interview records. The results show that use of a bonus point system affects the management of domestic waste by improving the accuracy and enhancing the awareness of garbage sorting. Overall, residents support the system and benefit from it, which increases participation and consciousness of environmental protection. However, continuous publicity and coordination of various policies are required to promote the wide-range implementation and sustainable development of this system.
Residential Spatial Differentiation Based on Urban Housing Types—An Empirical Study of Xiamen Island, China
Authors: Sun Caige , Lin Tao , Zhao Yu , Lin Meixia , Yu Zhaowu
Published: October 2017

Residential spatial differentiation, also called residential segregation, is a representation of the differentiation of social stratum in economic income, social status, education degree, lifestyle, and other aspects, based on an urban geographical space. In this paper, Xiamen Island is taken as example to calculate the dissimilarity index and the multi-group dissimilarity index at three scales (districts, sub-districts, and communities) by using the land area, population size, and green space area of different housing types. The characteristics of residential differentiation are analyzed. It is found that both spatial differentiation and multi-group spatial differentiation have significant scale effects. The smaller the scale of the spatial statistics unit, the larger the spatial differentiation and multi-group spatial differentiation. Significant differences are found in residential differentiation among different housing types. The residential differentiation is, not only demonstrated in land area and population size, but also in the resources of green space. More importantly, a balanced allocation of green space will help to reduce the degree of residential differentiation. With urban expansion and social-economic development, residential spatial differentiation will likely change. An understanding of residential differentiation is a guide for urban master planning and detailed regulatory planning. It will help to promote social harmonious development and urban sustainable development by the reasonable configuration of land and resources.

Published: October 2017

By evaluating green process innovation and its innovator’s benefit including short- and long-term dimensions, we first analyzed the relationship between green process innovation and its benefits. Second, we set up a regression model to test the hypotheses using 267 survey data from coal mining firms in China. Finally, we verified the positive relationship between green process innovation and its long-term benefit, and the non-significant relationship between green process innovation and its short-term benefit, and the mediating effect played by firm image in the long run.
Estimating River Depth from SWOT-Type Observables Obtained by Satellite Altimetry and Imagery
Authors: Tourian Mohammad , Elmi Omid , Mohammadnejad Abolfazl , Sneeuw Nico
Published: October 2017

The proposed Surface Water and Ocean Topography (SWOT) mission aims to improve spaceborne estimates of river discharge through its measurements of water surface elevation, river width and slope. SWOT, however, will not observe baseflow depth, which limits its value in estimating river discharge especially for those rivers with heterogeneous channel geometry. In this study, we aim to obtain river depths from spaceborne observations together with in situ data of river discharge. We first obtain SWOT-like observables from current satellite techniques. We obtain river water level and slope time series from multi-mission altimetry and effective river width from satellite imagery (MODIS). We then employ a Gauss–Helmert adjustment model to estimate average river depth for 16 defined reaches along the Po River in Italy, for which we use our spaceborne observations in two recognized models for discharge estimation. The average river depth estimates along the Po River are validated against surveyed cross-section information, which shows a generally good agreement in the range of ∼10% relative root mean squared error. Furthermore, we analyzed the sensitivity of error in the estimated river depth to errors of individual parameters. We show that the estimated river depth is less influenced by errors of river width and river discharge, while it is strongly influenced by errors in water level. This result gives a perspective to the SWOT mission to infer river depth by coarse estimates of river width and discharge.
The Importance of Institutional Design for Distributed Local-Level Governance of Groundwater: The Case of California’s Sustainable Groundwater Management Act
Authors: Kiparsky Michael , Milman Anita , Owen Dave , Fisher Andrew
Published: October 2017

In many areas of the world, groundwater resources are increasingly stressed, and unsustainable use has become common. Where existing mechanisms for governing groundwater are ineffective or nonexistent, new ones need to be developed. Local level groundwater governance provides an intriguing alternative to top-down models, with the promise of enabling management to better match the diversity of physical and social conditions in groundwater basins. One such example is emerging in California, USA, where new state law requires new local agencies to self-organize and act to achieve sustainable groundwater management. In this article, we draw on insights from research on common pool resource management and natural resources governance to develop guidelines for institutional design for local groundwater governance, grounded in California’s developing experience. We offer nine criteria that can be used as principles or standards in the evaluation of institutional design for local level groundwater governance: scale, human capacity, funding, authority, independence, representation, participation, accountability, and transparency. We assert that local governance holds promise as an alternative to centralized governance in some settings but that its success will depend heavily on the details of its implementation. Further, for local implementation to achieve its promise, there remain important complementary roles for centralized governance. California’s developing experience with local level groundwater management in dozens of basins across the state provides a unique opportunity to test and assess the importance and influence of these criteria.
Low Impact Development Planning and Adaptation Decision-Making under Climate Change for a Community against Pluvial Flooding
Authors: Chen Pei-Yuan , Tung Ching-Pin , Li Yuan-Hua
Published: October 2017

This study integrates and develops methods, namely low impact development (LID) selection method and an LID spatial planning model, to enable decision-making to minimize pluvial flooding for a community. The objective is to minimize the flood risk under the worst case of the design storm within the budget constraints. Design storms in current and future climate scenarios are analyzed as input to the Storm Water Management Model (SWMM). Then, LID practices are selected based on the proposed procedure and a spatial planning model is built to identify the optimal LID layouts using the simulated annealing (SA) algorithm. The lower and upper bounds of the generated rainfall intensities of a five-year 1-h duration design storms for the Hadley Centre Global Environment Model version 2 for the atmosphere and oceans (HadGEM2-AO), the Norwegian Earth System Model (NorESM1-ME), and the CSIRO-Mk3.6.0 Atmosphere-Ocean GCM (CSIRO-Mk3.6.0) during 2021–2040 are derived. The LID selection helps efficiently identify appropriate LID. Results show that nearly no flood occurs under the optimal LID layouts found by the LID spatial planning model. Moreover, it is more optimal to invest in LID in the lower sub-catchments in LID planning when the budget is limited. These methods are generally applicable for a community using LIDs as adaptation measures against pluvial flooding.
Application of a Hybrid Interpolation Method Based on Support Vector Machine in the Precipitation Spatial Interpolation of Basins
Authors: Zhang Xiaoxiao , Liu Guodong , Wang Hantao , Li Xiaodong
Published: October 2017

In this paper, we applied the support vector machine (SVM) to the spatial interpolation of the multi-year average annual precipitation in the Three Gorges Region basin. By combining it with the inverse distance weighting and ordinary kriging method, we constructed the SVM residual inverse distance weighting, as well as the SVM residual kriging precipitation interpolation model and compared them with the inverse distance weighting, ordinary kriging, linear regression residual inverse distance weighting and linear regression residual kriging interpolation methods. The TRMM 3B43 V7 satellite precipitation information, which is processed by the latest revision algorithm, is used as the auxiliary variable for ground site precipitation interpolation along with latitude and elevation. Our results show that: (1) adding the TRMM 3B43 V7 satellite precipitation data as an auxiliary variable significantly improves the interpolation accuracy of the linear regression equation and SVM model; (2) the support vector machine hybrid interpolation method obtains superior interpolation results compared to the inverse distance weighting method, ordinary kriging method and linear regression hybrid interpolation method; (3) the interpolation accuracy of the SVM hybrid interpolation method depends on the SVM fitting degree, so we should choose a suitable fitting accuracy rather than the highest fitting accuracy; (4) the linear regression equation has a greater degree of dependency on the TRMM data than the SVM. The SVM accepts the TRMM data information while better maintaining its independence, taking into account that the TRMM data linear regression and linear regression hybrid interpolation method are not suitable for TRMM data evaluation.

Title: Laparoscopic Approach in Patient with Situs Inversus Totalis and Colelithiasis: a Case Report.

Background: Situs Inversus Totalis is a rare clinical condition that gives a mirror aspect to the position of the organs. It is a congenital condition and though it does not affect normal health or longevity, it may be a challenge in cases requiring surgical intervention.

Case: The authors report a case of cholelithiasis in a patient with previous diagnosis of Situs Inversus Totalis. The patient presented abdominal pain, related to eating and associated with nausea and vomiting. After the image exams, it was performed the surgical procedure, without intercurrences.

Conclusion:Situs Inversus Totalis is a challenge for surgical approach because of the mirrored configuration of the organs, which can lead to misdiagnosis. Using image exams anda complete evaluation of the patient helps the correct management in caso of surgical procedures, and consequently influence in the prognosis.
Thoracic Syndesmophytes Commonly Occur in the Absence of Lumbar Syndesmophytes in Ankylosing Spondylitis: A Computed Tomography Study
Authors: Tan Sovira , Yao Lawrence , Ward Michael M.
Published: October 2017

Objective.

To determine the extent of thoracic involvement with syndesmophytes in ankylosing spondylitis (AS) relative to lumbar involvement.

Methods.

We performed thoracolumbar spine computed tomography (CT) and lumbar radiography on 18 patients. We quantitated syndesmophytes in 11 intervertebral disc spaces and related these to the presence of syndesmophytes on lumbar radiographs.

Results.

Syndesmophytes were slightly more common in the thoracic than in the lumbar spine and bridging was significantly more common. Thoracic syndesmophytes were universally present in patients without visible lumbar syndesmophytes on either radiographs or CT.

Conclusion.

Syndesmophytes predominate in the thoracic spine. Lumbar radiographs underestimate the degree of thoracic involvement.
De l’intérêt heuristique du concept de « fantôme géographique » pour penser les régionalisations culturelles

Le passage en revue du postcolonial
Authors: Collier Anne-Claire
Published: October 2017

Cet article étudie six revues ayant publié un (ou deux) numéro(s) thématique(s) sur le postcolonial en 2006-2007. En adoptant un prisme circulatoire, nous souhaitons montrer que l’orientation de ces numéros (plus ou moins politique) est dépendante de l’identité de la revue et de la trajectoire des coordinateurs de ces numéros, la prise en compte des « traducteurs » dans une analyse de circulation internationale des idées est essentielle pour comprendre les distorsions et les retraductions que connaissent ces idées. Nous argumenterons finalement que ces numéros thématiques ont peu à voir avec la circulation des auteurs classiques du postcolonial mais correspondent plutôt à une repolitisation de l’espace intellectuel français au lendemain de l’année 2005.
L’institutionnalisation de domaines d’études pluridisciplinaires autour de 68
Authors: Dormoy-Rajramanan Christelle
Published: October 2017

Cet article propose une analyse socio-historique de demandes et offres d’institutionnalisation de domaines d’études pluridisciplinaires dans l’enseignement supérieur et la recherche, au cours des années 1950-1970. En étudiant, d’abord, les débats relatifs à la politique de la science et de l’enseignement supérieur et les acteurs qui y ont pris une part active (responsables politiques et administratifs, patronat, enseignants-chercheurs, étudiants), apparaissent des intérêts économiques, savants et militants comme ressorts de l’injonction croissante à la « pluridisciplinarité ». Cette dernière figure parmi les revendications majeures de la mobilisation universitaire de mai-juillet 1968, présentée comme une condition de l’amélioration de la formation des étudiants et du renouvellement des savoirs, d’un point de vue épistémologique et/ou « critique ». Entérinée par la loi Faure de 1968, la « pluridisciplinarité » constitue l’un des trois piliers de la refondation des universités dans l’après-68 et une institution telle que l’université de Paris VIII-Vincennes aura notamment pour prérogative de l’expérimenter, avec des usages entre science et militantisme qui ont contribué à la construction et l’évolution de certains savoirs, notamment relatifs aux femmes.
From disciplines to “studies”
Authors: Monteil Lucas , Romerio Alice
Published: October 2017

The studies are debated within the academic space, with regard to the structure of disciplines. They claim an ability to produce conceptual or paradigmatic shifts. Taking epistemic and analytical issues seriously, their study also implies understanding the long term of scientific institutionalization. The historical sociology of disciplines indicates that a process of segmentation underlies the modern development of academic and scientific life. The analysis of their development argues for their reinstatement in historically changing power structures. Interdisciplinarity questions the future of the disciplinary organization of science. The emergence of studies appears to be the high point of recent transformations in the academic space.

Published: October 2017

Neer type II distal clavicle fractures are inherently unstable. The purpose of this study was to review the outcome of Neer type II distal clavicle fractures arthroscopically treated using a suspensory cortical button technique. Between 2008 and 2012, a total of 17 Neer type IIB fractures were managed operatively at the authors' institution. Functional outcomes were assessed using the pain score, the Disabilities of the Arm, Shoulder and Hand score, the Penn Shoulder Score, and the American Shoulder and Elbow Surgeons score. Radiographic union was also assessed. At a mean of 1 year, the mean pain score was 0.9±1.1, the mean Disabilities of the Arm, Shoulder and Hand score was 10.9±11.1, the mean Penn Shoulder Score was 90.3±7.9, and the mean American Shoulder and Elbow Surgeons score was 90.1±10.1. Radiographic union occurred in 14 patients. An all-arthroscopic surgical fixation of Neer type II distal clavicle fractures using a suspensory cortical button technique can result in a predictable outcome with a low complication rate. [

Published: October 2017

The purpose of this study was to evaluate functional outcomes for hemiarthroplasty using a direct anterior approach or a direct lateral approach for femoral neck fracture. This retrospective review used data collected from a single institution between 2006 and 2016. Eighty-five and 75 consecutive patients who underwent hemiarthroplasty via a direct anterior approach and a direct lateral approach, respectively, met inclusion criteria. All patients with femoral neck fractures were treated by 1 of 2 fellowship-trained orthopedic surgeons using the direct anterior approach or the direct lateral approach to hemiarthroplasty. Disposition, ambulation, and other perioperative surgical outcomes were compared between the cohorts. Compared with the direct lateral cohort, the direct anterior cohort had a shorter mean operative time (2.4 minutes,
P
<.01), a shorter mean length of hospital stay (2.7 days,
P
<.01), and a smaller mean decrease in hemoglobin postoperatively (0.7 g/dL,
P
<.01). No significant difference was observed between the cohorts for postoperative disposition, the number of feet ambulated on the second postoperative day, or the prevalence of ambulatory decline at 4- to 6-week and 4- to 6-month follow-up visits. Compared with the direct lateral approach, the direct anterior approach may benefit patients by small, but statistically significant, improvements in blood loss, surgical time, and length of hospital stay after hemiarthroplasty. However, the direct anterior approach does not appear to decrease the likelihood of transfer to a skilled nursing facility postoperatively or accelerate return to preoperative function. [

Published: October 2017

El conocimiento detallado de los endemismos pirenaicos resulta de gran utilidad en la adopción de medidas de conservación y en la investigación de patrones ecológicos de la flora. Describimos la distribución espacial y distintos aspectos florísticos y ecológicos de la lista revisada de endemismos pirenaicos tras la edición digital del “Atlas de flora vascular de los Pirineos”. Las 88 especies endémicas genuinas representan el 2,4% del conjunto de la flora pirenaica, se incluyen en 27 familias taxonómicas y se concentran en la parte central de la cadena. Los endemismos estudiados presentan notables diferencias ecológicas respecto al conjunto de la flora, en términos de una distribución territorial más reducida y localización en altitudes más elevadas, pero no presentan una distribución fragmentada en el conjunto de los Pirineos. Su distribución también indica que la dispersión Este-Oeste es más limitada que la Norte-Sur, a pesar de la barrera altitudinal del eje de la cordillera. Los endemismos son mayoritariamente caméfitos y están más representados en los hábitats rocosos calizos. En conjunto, estos resultados indican que el aislamiento durante las glaciaciones puede haber sido moderado y sirven como punto de partida para futuras investigaciones.
Impact of Outbound Logistics in Purchase Decision of Small Electronic Home Appliance Traders in Chittagong
Authors: Ahmed Mohammad Naveed
Published: October 2017

Outbound logistics focuses on the distribution to the point of sales, such as - collection, storage, and distribution systems etc. Marketers must understand – what the customer wants in terms of logistics and how it can create value to the customers? Based on this scenario, this study focuses on the fact that lack of understanding about the elements of outbound logistics is leading to lack of identifying it as value creation tool to impact the purchase decision in home appliances industry. In total around 490 home appliance traders is selected based on convenience from Chittagong city and interviewed based on a questionnaire in May 2016. Factor Analysis is used to identify the most relevant factors from 14 variables and then a regression analysis is used to show how each of those factors related to outbound logistics in small home appliance sector is impacting the purchase decision. The outcome is the trader's purchase decision equation which a marketer can use to identify the elements of outbound logistics where he can focus more to strengthen his logistics channel.

With practically all the service providers offering products and services with cloud features and functionality and investing in creating a cloud computing ecosystem, it has become important to understand what these ecosystem means to the organizations based out of UAE who have to decide whether to adopt cloud computing or shun it. There are several factors impacting an organization's decision on its choice of cloud computing adoption (like data security, Legal implications and derived benefits especially in UAE) (Al Tamimi & Company, 2005). There is a need for an assessment of cloud ecosystem in UAE which would be one of the significant factors considered cloud adoption in this region. This study analyzes the current cloud ecosystem providers in UAE and their product and services on cloud computing. It also tries to relate the relation between the cloud ecosystem and the factors impacting organization's decision to adopt cloud computing.

Accounting students should enrich themselves with the technical knowledge, critical thinking, and problem-solving skills to be successful in today's competitive environment. To reach these objectives, they should be highly engaged and motivated in the learning process. It has been argued that games can play a useful role in making the study of accounting more interesting, hence increasing motivation. The research presented in this paper explores the impact of learning in an introductory accounting course attributable to the use of games supplementary to the traditional teaching methods. The perceptions of 18 students and six faculties at a tertiary institution in the United Arab Emirates relating to the integration of games in an introductory accounting course were uncovered through semi structured interviews. Prior to the students being interviewed, they had been given the opportunity to play three different types of games in a controlled classroom. The exploratory research found that faculty and students believe that games can motivate students and maintain their enthusiasm and interest in learning in an introductory accounting course. However, faculty are generally not in a favour of introducing accounting concepts in introductory accounting course to students through games. They do agree that games should be used for practicing homework and as fillers in an introductory accounting course. The study accentuates that games are one of the motivational factors to maintain student's interest in the course consistently. This exploratory research will give an idea of innovative learning in the accounting class. It will assist accounting faculty to understand the fact that the use of games can make complex and quantitative subjects like accounting easy to understand and fun without sacrificing the quality of students' foundation learning in the subject.

Vehicular User Equipment (UE) performance during mobility faces two issues relating to signaling and transmission, namely Handover (HO) and link adaptation. This paper shows that both processes are experiencing degradation during mobility and that vehicular UEs suffer from call drops and loss of connections. Therefore, this work presents an effective technique using Mobile-Femtos to improve vehicular UEs' HO process and link quality. Results show that vehicular UEs attached to a Mobile-Femto achieved better signalling and Link Ergodic capacity and as a consequence the outage probability was reduced. The achieved results indicated that deploying Mobile-Femtos under 25dB Vehicular Penetration Loss (VPL) has improved the vehicular UE Link Ergodic capacity by 1% and reduced the signal outage probability by 1.8% compared to the eNB direct transmission. Consequently, Drop Calls Probability (DCP) and Block Calls Probability (BCP) have been reduced by 7% and 14% respectively compared to the direct transmission from the eNB.

In this paper, a novel security-enhanced agile software development process, SEAP, is introduced. It has been designed, tested, and implemented at Ericsson AB, specifically in the development of a mobile money transfer system. Two important features of SEAP are 1) that it includes additional security competences, and 2) that it includes the continuous conduction of an integrated risk analysis for identifying potential threats. As a general finding of implementing SEAP in software development, the developers solve a large proportion of the risks in a timely, yet cost-efficient manner. The default agile software development process at Ericsson AB, i.e. where SEAP was not included, required significantly more employee hours spent for every risk identified compared to when integrating SEAP. The default development process left 50.0% of the risks unattended in the software version that was released, while the application of SEAP reduced that figure to 22.5%. Furthermore, SEAP increased the proportion of risks that were corrected from 12.5% to 67.9%, a more than five times increment.
Hardenability of ASSAB 760 Steel during Tempering for Punch Holder Applications
Authors: Anggraini Lydia
Published: October 2017

The purpose of this research was to evaluate the hardenability of ASSAB 760 (equivalent to AISI 1045 and JIS S45C) steel subjected to the gas cementation, the quenching and the tempering processes. Gas cementation is a heat treatment surface process by means of carbon diffusing into steel. This process is carried out in a furnace in a fluidized bed by using media of liquid petroleum gas (LPG) and nitrogen gas at a temperature of 1203 K and various holding times of 7.2, 10.8 and 14.4 ks, respectively. The rapid quenching process is carried out in an oil media for 420 sec. In order to remove the tension in the specimen, the tempering process is carried out in a furnace at a low temperature of 473 K with holding time of 3.6 ks. The result shows that, the Vickers hardness values can be achieved from 568 to 584 HV. Therefore, it is confirmed that by using these processes, the hardening of ASSAB 760 steel can be carried out and the punch holder can be manufactured.

Aluminum dross residue is a by-product produced at secondary re-melt plants where aluminum scraps are recycled. In this study, aluminum dross residue was utilized as a major component in the fabrication of unglazed ceramics for wall tile applications. The use of this by-product can reduce the landfill and environmental problems. The amount of aluminum dross residue used in the ceramic compositions varied in the range 50-90 wt.%. Other components utilized in the ceramic compositions included recycled glass alumino-silicate based clays. Firing was carried out between 1140 and 1200°C with 4h holding time which resulted in strong ceramic samples. Alpha-alumina, α-Al2O3 was the main crystalline phase found in all sintered ceramic samples. The appearance of mullite phase, Al6Si2O13 was evident in all fired samples. Overall, the synthesized ceramics had excellent densification characteristics when the amount of aluminum dross residue was less than 70 wt% in the ceramic composition.

Generally, metal injection molding (MIM) method utilizes SS 17-4 PH as material for application of orthodontic bracket. One of the process of MIM is thermal debinding, which binder is eliminated by thermal energy. In this study, thermal debinding process is conducted with variation of temperature, i.e. 480, 510, and 540°C, holding time, i.e. 0.5, 1 and 2 hours, heating rate, i.e. 0.5, 1, 1.5, and 2°C/min.The effect of temperature shows that the increased temperature will result in the mass reduction percentage due to formation of oxide on the sample, which will be proven through TGA testing. The highest mass reduction was 6.4137 wt% which was obtained at 480°C. For the variation of holding time, the longer the holding time will result in increased mass reduction and the highest mas reduction was 6.255 wt% which was obtained during 2 hours of holding time. For the heating rate, the slower the heating rate will result in increased mass reduction and decreased the presence of crack formation. The best variable was obtained at heating rate of 0.5°C/min, which resulted mass reduction of 6.2488 wt% and less crack formation.

The use of industrial by-products could provide a feasible solutions for the construction industry to reduce the strain on supply of natural aggregate as well as achieving the concept of environmentally friendly binder material by replacing part of Portland cement. This paper reports the results of an experimental study, mainly on the permeability and porosity characteristic of pervious concrete developed by substituting 26% Portland cement with air-cooled blast furnace slag and replacing part of natural coarse aggregate with granular blast furnace slag of different aggregate size and different water/cement ratio. The pervious concrete with lower water cement ratio and 25% GBFS affected either the porosity or the compressive strength of the pervious concrete. As expected, the porosity increased in pervious concrete with bigger aggregate size, but decreased when the smaller aggregate size was used. Partial substitution of coarse aggregate with granular GBFS of the same gradation size did not affect the permeability coefficient. Specimens developed using water cement ratio of 0.34 and coarser aggregate size tend to have a greater water permebility compared with those of 0.3 water/cement ratio.
