Late-Onset Nonthrombotic Left Common Iliac Vein Compression Secondary to Degenerative Lumbar Disc: A Case Report of May-Thurner Variant
Authors: Khalid Salman , Youn Young Jin , Azrin Michael , Lee Juyong
Published: August 2018

May-Thurner syndrome (MTS) refers to venous outflow obstruction caused by extrinsic compression of the left common iliac vein (LCIV) by the overlying pulsatile right common iliac artery against lumbar vertebrae. The classic clinical presentation is acute unilateral left leg painful swelling due to deep venous thrombosis in a young woman in the second or third decade of life. We present a case of a 66-year-old woman who presented with late-onset left leg swelling caused by nonthrombotic venous hypertension due to degenerative lumbar disc bulge leading to LCIV compression against the left common iliac artery which was confirmed by computed tomography and intravascular ultrasound. Our case highlights the importance of high index of suspicion for MTS in elderly patients with unilateral leg swelling and the importance of multimodality imaging for understanding the mechanism and appropriate treatment of MTS.
A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams
Authors: Xu Bin , Zhou Yang , Liu Jingmao , Yu Xiang
Published: August 2018

Equivalent linear dynamic analysis is the primary method of analysis for concrete-faced rockfill dams during earthquake. However, this method cannot be directly used to estimate permanent deformation during earthquake, which is important to evaluate the dynamic safety of concrete-faced rockfill dams. To bridge this gap, an elasto-plastic dynamic response procedure based on finite element method is presented to estimate the construction, impoundment, and dynamic characteristics of concrete-faced rockfill dams. This procedure involves a generalized plasticity model for rockfill materials and an ideal elasto-plastic model for interface between concrete face slab and rockfill material. The construction, impounding process, and seismic behavior of a 150-m-tall concrete-faced rockfill dam were simulated using seismic motion based on Chinese code for seismic design of hydraulic structures of hydropower project with the peak ground acceleration of 0.3 g as an excitation to validate the procedure. On the basis of the numerical simulation results of the step-by-step construction, reservoir impoundment and seismic response of a concrete-faced rockfill dam, dam settlement, joint deformation, stress, and deformation of slab were analyzed. The results indicate that the dam settlement and deformation of joint can be directly obtained by the procedure during earthquake. The construction, impoundment, and seismic analysis could be considered in one procedure.
The EPA Cancer Risk Assessment Default Model Proposal: Moving Away From the LNT
Authors: Calabrese Edward J. , Hanekamp Jaap C. , Shamoun Dima Yazji
Published: August 2018

This article strongly supports the Environmental Protection Agency proposal to make significant changes in their cancer risk assessment principles and practices by moving away from the use of the linear nonthreshold (LNT) dose–response as the default model. An alternate approach is proposed based on model uncertainty which integrates the most scientifically supportable features of the threshold, hormesis, and LNT models to identify the doses that optimize population-based responses (ie, maximize health benefits/minimize health harm). This novel approach for cancer risk assessment represents a significant improvement to the current LNT default method from scientific and public health perspectives.
Cancer is not associated with higher short or long-term mortality after successful resuscitation from out-of-hospital cardiac arrest when adjusting for prognostic factors
Authors: Winther-Jensen Matilde , Kjaergaard Jesper , Hassager Christian , Køber Lars , Lippert Freddy , Søholm Helle
Published: August 2018

Objective:

As the prevalence of malignancies in the general population increases, the odds of an out-of-hospital cardiac arrest (OHCA) patient having a history of cancer likewise increases, and the impact on post-cardiac arrest care and mortality is not well known. We aimed to investigate 30-day and 1-year mortality after successful resuscitation in patients with cancer prior to OHCA compared with OHCA patients without a previous cancer diagnosis.

Methods:

A cohort of 993 consecutive OHCA patients with successful resuscitation during 2007–2011 was included. Vital status was obtained from the Danish Civil Register, and cancer diagnoses from the Danish National Patient Register dating back to 1994. Primary endpoints were 30-day, 1-year and long-term mortality (no cancer: mean 811 days; cancer: mean 406 days), analysed by Cox regression. Functional status assessed by cerebral performance category at discharge and use of post-resuscitation care were secondary endpoints.

Results:

A total of 119 patients (12%) were diagnosed with cancer prior to OHCA. Mortality was higher in patients with cancer (30-day 69% vs. 58%, P=0.01); however, after adjustment for prognostic factors cancer was no longer associated with higher mortality (hazard ratio (HR)30 days 0.98, 95% confidence interval (CI) 0.76–1.27, P=0.88; HR1 year 0.99, 95% CI 0.78–1.27, P=0.96 HRend of follow-up 0.95, 95% CI 0.75–1.20, P=0.67). Favourable cerebral performance category scores in patients alive at discharge did not differ (cerebral performance category 1 or 2 n=310 (84%) vs. n=31 (84%), P=1).

Conclusion:

Cancer prior to OHCA was not associated with higher mortality in patients successfully resuscitated from OHCA when adjusting for confounders. Cancer prior to OHCA should be used with caution when performing prognostication after OHCA.
Self-Control in Learning for Healthy Living Among Students in a Nigerian College of Education
Authors: Nwagu Evelyn N. , Enebechi Jude C. , Odo Amelia N.
Published: August 2018

The rapid increase in health information requires that learners exert some degree of self-control in learning to make an appropriate selection of what to learn about healthy living. The objective of this study was to determine the students’ level of self-control in learning for healthy living. A questionnaire adapted from the self-control subscale of the Self-Directed Learning Readiness (SDLR) Scale developed by Fisher, King, and Tague was used in determining the levels of self-control in learning for healthy living among students in Enugu State College of Education (Technical), Enugu, Nigeria. The study revealed that the students’ level of self-control was a little less than the recommended level. A significant difference was found in the male and female students’ level of self-control in learning for healthy living with the male students possessing a higher level of self-control. Significant differences also occurred in the students’ level of self-control in learning for healthy living when the students were classified based on their courses of study. The students’ level of self-control in learning for healthy living at the College of Education (Technical), Enugu, needs to be improved. Educators at the college should employ self-control-enhancing strategies to improve the level of self-control in learning among the students.
Why topology matters in predicting human activities
Authors: Ma Ding , Omer Itzhak , Osaragi Toshihiro , Sandberg Mats , Jiang Bin
Published: August 2018

Geographic space is better understood through the topological relationship of the underlying streets (note: entire streets rather than street segments), which enables us to see scaling or fractal or living structure of far more less-connected streets than well-connected ones. It is this underlying scaling structure that makes human activities predictable, albeit in the sense of collective rather than individual human moving behavior. This topological analysis has not yet received its deserved attention in the literature, as many researchers continue to rely on segment analysis for predicting human activities. The segment analysis-based methods are essentially geometric, with a focus on geometric details of locations, lengths, and directions, and are unable to reveal the scaling property, which means they cannot be used for the prediction of human activities. We conducted a series of case studies using London streets and tweet location data, based on related concepts such as natural streets, and natural street segments (or street segments for short), axial lines, and axial line segments (or line segments for short). We found that natural streets are the best representation in terms of human activities or traffic prediction, followed by axial lines, and that neither street segments nor line segments bear a good correlation between network parameters and tweet locations. These findings point to the fact that the reason why space syntax based on axial lines, or the kind of topological analysis in general, works has little to do with individual human travel behavior or ways that humans conceptualize distances or spaces. Instead, it is the underlying scaling hierarchy of streets – numerous least-connected, a very few most-connected, and some in between the least- and most-connected – that makes human activities predictable.
Natural History and Clinical Significance of Multiple Cysts in a Single Choroid Plexus
Authors: Petrikovsky B. M. , Terrani M. , Sichinava L. G.
Published: August 2018

Different types and locations of choroid plexus cysts (CPCs) have been described, including oversized and bilateral. It appears that the type, size, and number of CPCs are correlated with various degrees of aneuploidy risk. This report deals with the natural history and significance of CPCs filling only one choroid plexus. Multiple CPCs filling the entire choroid plexus were detected in 9 of 4211 consecutive second-trimester sonographic examinations. Karyotyping via amniocentesis or neonatal blood analysis was performed in all cases. CPCs in a single choroid plexus were associated with transient ventriculomegaly in five of nine fetuses. Resolution of CPCs took place between 25 and 33 weeks of pregnancy, with most resolving after the 30th week. Karyotyping revealed normal results in all cases. Favorable prognosis of newly described multiple CPCs in a single choroid plexus should be mentioned during patient counseling.
Structural, mechanical and Raman spectroscopic characterization of the layered uranyl silicate mineral, uranophane-α, by density functional theory methods
Authors: Colmenero Francisco , Timón Vicente , Bonales Laura J. , Cobos Joaquín
Published: August 2018

The layered uranyl silicate clay-like mineral, uranophane-α, Ca(UO2)2(SiO3OH)2·5H2O, was studied by first-principles calculations based on the density functional theory method. The structure, observed in nature in a wide variety of compounds having the uranophane sheet anion topology, is confirmed here for the first time by means of rigorous theoretical solid-state calculations. The computed lattice parameters, bond lengths and bond angles were in very good agreement with the experimental ones, and the calculated X-ray powder trace accurately reproduced its experimental counterpart. The mechanical properties of uranophane-α, for which there are no experimental data for terms of comparison, were determined, and the satisfaction of the mechanical stability Born conditions of the structure was demonstrated by calculations of the elasticity tensor. The Raman spectrum was computed by the density functional perturbation theory and compared with the experimental spectrum. The vibrational properties of this mineral were well characterized, showing a good performance in all of the studied spectral range. Theoretical methods allowed assignment of the Raman bands to vibrations localized in different fragments within the crystal unit cell. Finally, the possibility of incorporation of strontium inside the uranophane structure was studied. The computed structure, X-ray powder trace and Raman spectrum of Sr-exchanged uranophane were very close to those of the ordinary Ca-uranophane.

Formation of 53BP1 foci and ATM activation under oxidative stress is facilitated by RNA:DNA hybrids and loss of ATM-53BP1 expression promotes photoreceptor cell survival in mice
Authors: Bhatia Vaibhav , Valdés-Sánchez Lourdes , Rodriguez-Martinez Daniel , Bhattacharya Shom Shankar
Published: August 2018

Background: Photoreceptors, light-sensing neurons in retina, are central to vision. Photoreceptor cell death (PCD) is observed in most inherited and acquired retinal dystrophies. But the underlying molecular mechanism of PCD is unclear. Photoreceptors are sturdy neurons that survive high oxidative and phototoxic stress, which are known threats to genome stability. Unexpectedly, DNA damage response in mice photoreceptors is compromised; mainly due to loss of crucial DNA repair proteins, ATM and 53BP1. We tried to understand the molecular function of ATM and 53BP1 in response to oxidative stress and how suppression of DNA repair response in mice retina affect photoreceptor cell survival.

Methods: We use the state of art cell biology methods and structure-function analysis of mice retina. RNA:DNA hybrids (S9.6 antibody and Hybrid-binding domain of RNaseH1) and DNA repair foci (gH2AX and 53BP1) are quantified by confocal microscopy, in retinal sections and cultured cell lines. Oxidative stress, DNA double strand break, RNaseH1 expression and small-molecule kinase-inhibitors were used to understand the role of ATM and RNA:DNA hybrids in DNA repair. Lastly, retinal structure and function of ATM deficient mice, in Retinal degeneration 1 (Pde6brd1) background, is studied using Immunohistochemistry and Electroretinography.

Results: Our work has three novel findings: firstly, both human and mice photoreceptor cells specifically accumulate RNA:DNA hybrids, a structure formed by re-hybridization of nascent RNA with template DNA during transcription. Secondly, RNA:DNA-hybrids promote ataxia-telangiectasia mutated (ATM) activation during oxidative stress and 53BP1-foci formation during downstream DNA repair process. Thirdly, loss of ATM -in murine photoreceptors- protract DNA repair but also promote their survival. 

Conclusions: We propose that due to high oxidative stress and accumulation of RNA:DNA-hybrids in photoreceptors, expression of ATM is tightly regulated to prevent PCD. Inefficient regulation of ATM expression could be central to PCD and inhibition of ATM-activation could suppress PCD in retinal dystrophy patients.
Assessing the feasibility of mobilisation of C0–C3 cervical segments to reduce headache in migraineurs
Authors: Davidson Ian , Crooks Kathryn , Newington Lisa , Pilling Mark , Todd Christopher
Published: August 2018

Background:

Migraine headache poses a major public health problem. Pharmacological treatment is the most common management strategy, however patients are increasingly seeking alternative treatments. The Watson Headache® Approach (targeted and sustained non-manipulative mobilisation on C0–C3) is used to reduce headache symptoms and provide sustained relief. This research aimed to assess this approach as a treatment strategy for migraine headache and to provide data to inform a subsequent randomised controlled trial.

Methods:

One-hundred-and-one migraineurs were randomised to either the ‘treat now’ (n=54) or ‘wait list’ (n=47) group. Physiotherapists trained in the approach provided the intervention. Participants received six sessions. Outcome data were collected as a headache diary, including: headache score, headache days, headache duration, pain and medication use. Follow up was immediately post treatment (FU0) and at 3 (FU3), 6 (FU6) and 12 months (FU12).

Results:

Between-group analysis found no difference between the wait list group at baseline 2 and the treat now group at FU0 for any of the variables of interest. Within-group analysis found that after treatment participants experienced a reduction in headache intensity (P=0.007) and duration (P<0.001), had fewer headache days/28 days (P<0.001), hours of severe migraine headache (P<0.001) and used 20% fewer medications compared with before treatment (P<0.001).

Conclusion:

The Watson Headache® Approach shows promise as a potential strategy for migraine management, however further work is required to assess the efficacy of this technique in a larger, randomised placebo-controlled trial. Future studies should aim to identify those most likely to benefit from treatment and who may be at risk of potential adverse event.
Validation of the Behavioural Regulation in Exercise Questionnaire-2 for adults with chronic musculoskeletal pain
Authors: Brooks Jessica M , Kaya Cahit , Chan Fong , Thompson Kerry , Sánchez Jennifer , Cotton Brandi Parker , Fortuna Karen
Published: August 2018

Background/Aims:

The Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) has demonstrated reliability and validity in the general population; yet the psychometric properties have not been tested among rehabilitation populations, such as persons experiencing chronic musculoskeletal pain. The objective of the current study was to examine the factorial structure and psychometric properties of the BREQ-2 in a sample of adults with chronic musculoskeletal pain.

Methods:

Adults with chronic musculoskeletal pain (n=211) were recruited from clinical and community networks in the United States. Data were collected using a cross-sectional online survey and analysed using confirmatory factor analysis, multiple indicators multiple causes analysis, and correlational techniques. Participants completed the BREQ-2 and other measures relevant to self-determination theory, including outcome expectancies, self-efficacy and family and friend support for physical activity and exercise.

Findings:

Results indicated the intercorrelated model fit the data well. The five factors of amotivation, external regulation, introjected regulation, identified regulation and intrinsic regulation toward physical activity and exercise demonstrated good reliability and construct validity.

Conclusions:

This study provides evidence of factorial and construct validity for the BREQ-2 among people with chronic musculoskeletal pain. Implications for rehabilitation practitioners and researchers are discussed.
Educating mental health staff in sensory approaches using an e-learning package: a 3-month follow-up
Authors: Meredith Pamela , Hutchens Sarah , Kerley Lachlan , Taylor Michelle , Slattery Maddy
Published: August 2018

Background/Aims:

Emerging evidence suggests that people with mental illness report improved emotional regulation through the use of sensory approaches; however, incorporating sensory approaches into clinical practice requires training. While use of a sensory approaches e-learning training package has revealed short-term improvements in staff knowledge, confidence and attitudes towards sensory approaches, the preservation of these changes over time has not been investigated.

Methods:

A multi-method longitudinal survey design was used. Data were collected pre-, post- and 3-months after participants completed a sensory approaches e-learning package. Surveys included multiple-choice questions, a Knowledge, Confidence and Attitudes Scale, and questions regarding the implementation of sensory approaches.

Findings:

Three months following course completion, participant scores on knowledge (actual and perceived), confidence and attitudes about sensory approaches had decreased slightly from scores immediately after training; however, perceived knowledge and confidence remained significantly higher than pre-training. Most participants reported that they were implementing more sensory approaches 3 months after completion of the package. Key barriers to the implementation of sensory approaches were staff roles and time/resources.

Conclusions:

This study revealed sustained improvements in clinician confidence and knowledge following completion of the package and identified factors influencing implementation. Findings highlight the need for continued educational support and workplace changes to increase the inclusion of sensory approaches in clinical practice.

Published: August 2018

BACKGROUND

Biomarkers are needed for noninvasive early detection of gastric cancer (GC). We investigated salivary extracellular RNA (exRNA) biomarkers as potential clinical evaluation tools for GC.

METHODS

Unstimulated whole saliva samples were prospectively collected from 294 individuals (163 GC and 131 non-GC patients) who underwent endoscopic evaluation at the Samsung Medical Center in Korea. Salivary transcriptomes of 63 GC and 31 non-GC patients were profiled, and mRNA biomarker candidates were verified with reverse transcription quantitative real-time PCR (RT-qPCR). In parallel, microRNA (miRNA) biomarkers were profiled and verified with saliva samples from 10 GC and 10 non-GC patients. Candidate biomarkers were validated with RT-qPCR in an independent cohort of 100/100 saliva samples from GC and non-GC patients. Validated individual markers were configured into a best performance panel.

RESULTS

We identified 30 mRNA and 15 miRNA candidates whose expression pattern associated with the presence of GC. Among them, 12 mRNA and 6 miRNA candidates were verified with the discovery cohort by RT-qPCR and further validated with the independent cohort (n = 200). The configured biomarker panel consisted of 3 mRNAs (SPINK7, PPL, and SEMA4B) and 2 miRNAs (MIR140-5p and MIR301a), which were all significantly down-regulated in the GC group, and yielded an area under the ROC curve (AUC) of 0.81 (95% CI, 0.72–0.89). When combined with demographic factors, the AUC of the biomarker panel reached 0.87 (95% CI, 0.80–0.93).

CONCLUSIONS

We have discovered and validated a panel of salivary exRNA biomarkers with credible clinical performance for the detection of GC. Our study demonstrates the potential utility of salivary exRNA biomarkers in screening and risk assessment for GC.

Micro and macro approaches to sustainability in fashion and design
Authors: Lin Dian-Jen
Published: August 2018

What is sustainability? How do we define and approach sustainable practices? How is sustainability perceived in the context of fashion? In the current fashion industry, terms like ‘organic’ or ‘recycled’ materials are often referred to as indicators for sustainable practices. However, is this the future of sustainability in fashion? If we take one step back from the fashion world and look at how sustainable practices are pursued in other contexts, we can easily discover a blind spot that is hardly mentioned or attempted in the fashion context.
Designing a sustainable brand strategy for the fashion industry
Authors: Moorhouse Debbie , Moorhouse Danielle
Published: August 2018

Fashion is widely considered the second most destructive industry to the environment, with a global supply chain employing 58 million people worldwide. During the period of 2000–14, clothing production increased by 50 per cent, as fast-fashion evolved and the luxury sector ascended. Recently, a number of high-profile fashion designers are taking the decision to consciously depart from the constraints of the seasonal fashion calendar, enabling them to reconnect with the creative process, focusing on quality and customer experience. ‘With fashion there is too much fear, not enough time, and not enough love’ (Elbaz 2017). While sustainable fashion has often been considered a consumer-led movement, which brands have been pressured to act upon, it is important that businesses demonstrate social responsibility through a collaborative approach incorporating design, innovation, technology and communication to successfully create desirable sustainable products with integrity. With constant news updates as a result of technology and the overriding competitiveness of social media, brands need to design and launch unique products that attract attention. This article will explore the connection between sustainable design and brand identity in relation to the fashion industry. The article will identify economic and commercial business opportunities, incorporating how combining sustainable design principles with communicative story telling provides additional emotional value for both designer and consumer, and aligning brands with social and environmental issues that are directly related to the products they are selling.
Mixing as a performance: Educating tertiary students in the art of playing audio equipment whilst mixing popular music
Authors: Anthony Brendan
Published: August 2018

The development of technology and popular music production creative practice are forever interrelated; following the introduction of digital technology there have been significant changes in the way popular musicians mix their music. Analogue eras culminated in pre-automation days with mixers manipulating tactile devices like pots and faders on analogue consoles in a manner akin to that of a performance. During this process many mixers would use the studio as an instrument to craft a mix. However, the Digital Audio Workstation has made mixing a more computer-based practice, which perhaps involves different performance practices than in decades past. This article intends to re-position the current understanding of mixing as a performance and presents a case study of a working higher education pedagogical framework for teaching mixing as a performance. Therefore, this article is intended as a pedagogical starting point for popular music creative practice in higher education.
Rock god or game guru: Using Rocksmith to learn to play a guitar
Authors: Graham Kevin , Schofield Damian
Published: August 2018

Multiple studies were undertaken to investigate the effectiveness of the video game Rocksmith (Ubisoft, 2011) as a learning tool, specifically assessing whether players actually learn to play the guitar while playing the game. The study also examines player motivations and attempts to understand the reasons different players spent time playing the game. One of the stated purposes of the Rocksmith video game is to teach users how to play the guitar, and a number of claims have been made of the effectiveness of this game as a musical training system with little empirical evidence to back up these claims. A number of experiments and user tests were administered in order to improve understanding of how the game educates its users and improves their skill levels when playing an electric guitar. The type of experience the users expected and experienced within the Rocksmith game was also investigated. By structuring the study in a way that allowed the users to have freedom of choice in the testing process, it was anticipated that an experience that felt natural to the participant would occur.
Envisioning Arctic Futures: Digital and Otherwise
Authors: Bodenhorn Barbara , Ulturgasheva Olga
Published: August 2018

The production of Never Alone (a recent video game incorporating Inupiaq narrative traditions and aesthetics) is one example of how indigenous peoples use digital technologies to spark young people’s interest in their own knowledge. Using comparative material from game players in Siberia and Alaska, this article explores interfaces between the knowledge needed to play such games and that required for hunting in real time. Combining attention to decolonizing education and new museology strategies, the authors suggest that the pedagogical impact of such games is strengthened when combined with face-to-face interactions with local knowledge holders. This, in turn, suggests the importance of recognizing the work of the museum as its capacity to animate knowledge, not simply to store it.

Poor germination and subsequent low grain yield of dry seeded upland rice in the existing anaerobic and short niche between lowland rice and dry season crops in the inland valley necessitate the screening of 19 rice varieties. The identification of vigorous growth and short duration upland rice variety in anaerobic condition would optimize this niche. The potted experiment was carried out in the screen house of the Department of Crop Science and Horticulture, Federal University Oye-Ekiti, Ikole campus in 2015 to screen and evaluate the performance of upland rice varieties in inundated soils with a view to selecting the suitable variety or varieties that will fit into the existing niche in the inland valley. The experiment was laid in a complete randomization design and replicated three times. The number of leaves, biomass and grain weight plant−1 of the varieties were significantly (P ≤ 0.05 %) different. The number of tillers observed in WAB 56-104, NERICA 4, NERICA 6, NERICA 3, NERICA 5, NERICA 10, NERICA 9, ARICA 4 NERICA 1, FARO 63, FARO 65 and NERICA 8 varieties were significantly (P < 0.05) lower than those of Igbemo varieties. The numbers of days to 50 % flowering of NERICA 1, NERICA 2, NERICA 10, NERICA 5, NERICA 9, NERICA 3, NERICA 7, NERICA 8, ARICA 4 and WAB 56-104 varieties were the lowest. Although Igbemo brown, Igbemo white varieties had the highest grain yields per plant, their maturity period exceeded the short period. Thus, NERICA 2 and NERICA 5 varieties which had lower number of days to flowering could be considered as candidate varieties that can be optimized in the niche in question.
Improved alarm flood analysis by cluster identification and alarm assignment
Authors: El Sakka Feras , Bloch Henry , Kinghorst Jakob , Fahimi Pirehgalin Mina , Fay Alexander , Vogel-Heuser Birgit
Published: August 2018

Alarm analysis aims to group similar and frequently occurring alarm sequences in alarm clusters. These clusters are so far identified by data-driven approaches based on the historical alarm data. To improve the alarm analysis, especially the handling of alarm floods, additional information can be integrated into state of the art alarm analysis approaches. This additional information consists of plant and process information, which improves the identification and detection of alarm clusters. Information such as neighborly relations of alarm sources or the heat transmission between two not directly connected alarm sources, improve the identification of alarm clusters. The handling of unknown alarms, which occur during runtime, and the assignment to known alarms and additionally to identified alarm clusters can be supported by process and plant information as well. Based on the combination of alarm analysis approaches and the evaluation of process and plant information, it seems feasible to identify causal coherent alarms within alarm floods. This improvement supports the plant operator to handle the abnormal situation by a reduction of the occurring alarms and information about the causal relations between alarms.

Evaluation of the Suitability of the Strain-Gauge Method for Measuring Deformations during the Fatigue Tests of Aviation Composite Structures
Authors: Rośkowicz Marek , Leszczyński Piotr
Published: August 2018

The paper discusses the results of selected fatigue tests of a motor glider’s insulated spar structure. The results of the experimental tests were used to assess the potential of the strain-gauge method for diagnosing the spar damage involving the unbolting of one of metal fittings in the spar pin. The usefulness of the deformation measurement method in the composite structure diagnostic process was confirmed, while simultaneously drawing attention to the need for conducting a process optimizing the number of sensors and their distribution on a tested object, in the context of the sensitivity of diagnostic signals received.
Design and Strength Analysis of Curved-Root Concept for Compressor Rotor Blade in Gas Turbine
Authors: Wdowiński Wojciech , Szymczyk Elżbieta , Jachimowicz Jerzy , Moneta Grzegorz
Published: August 2018

The motivation of the article is fatigue and fretting issue of the compressor rotor blades and disks. These phenomena can be caused by high contact pressures leading to fretting occurring on contact faces in the lock (blade-disk connection, attachment of the blade to the disk). Additionally, geometrical notches and high cyclic loading can initiate cracks and lead to engine failures. The paper presents finite element static and modal analyses of the axial compressor 3rd rotor stage (disk and blades) of the K-15 turbine engine. The analyses were performed for the original trapezoidal/dovetail lock geometry and its two modifications (new lock concepts) to optimize the stress state of the disk-blade assembly. The cyclic symmetry formulation was used to reduce modelling and computational effort.

We investigated, using density functional theory, the possible interaction sites and the nature of interaction, adsorption energy assessments, band gap energy evaluations, charge transfer analyses, and some diagnostic vibrational band assignments for valproic acid (VPA) and aluminum, silicon, and boron decorated fullerene systems. The present research shows that VPA has strong interaction with the doped fullerene cages particularly at its carbonyl edge. Therefore, these doped fullerenes can be suggested as possible drug delivery agents.

In this article, ZnO thin-film deposition on a glass substrate was done using microwave induced oxygen plasma based CVD system. The prepared thin-films were tested in terms of crystallinity and optical properties by varying the microwave power. The effect of power variation on the morphology and size of final products was carefully investigated. The crystal structure, chemical composition and morphology of the final products were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis spectroscopy, Raman spectroscopy and photoluminescence (PL). This technique confirmed the presence of hexagonal ZnO nanocrystals in all the thin-films. The minimum crystallite grain size as obtained from the XRD measurements was ~9.7 nm and the average diameter was ~18 nm.
An experimental study of the chipping process with focus on energy consumption and chipping angles

Published: August 2018

A series of chipping experiments were performed under both dynamic and quasi-static conditions in a laboratory wood chipper (dynamic) and in a MTS-servohydraulic testing machine (quasi-static). One aim with the experiments was to investigate the rate dependency of the energy consumption during chipping. Another aim was to try to determine the load per unit knife edge length required to initiate cutting. The experiments were carried out using different combinations of spout and edge angles. It was found that for large edge angles (keeping the spout angle constant at

30
°

30^\circ

) there was a slight rate dependency such that the energy consumption was larger at higher cutting rates which is quite in opposite of what is expected if wood is assumed to be a viscoelastic material. It was also found that to determine the force at initiation of cutting, is not a trivial task. Both Acoustic Emission monitoring and visual inspection was used to this end. The wood species used in this study was pine (Pinus silvestris).
Time-Dependency in Producers’ Price Adjustments: Evidence from Micro Panel Data
Authors: Nilsen Øivind A. , Pettersen Per Marius , Bratlie Joakim
Published: August 2018

Existing micro evidence of firms’ price changes tends to show a downward sloping hazard rate – the longer the price of a product has remained the same, the less likely it is that the price will change. Using a panel of Norwegian plant- and product-specific prices, we also find a downward sloping hazard when applying a Kaplan–Meier model. After having controlled for both observed and unobserved characteristics, we find flat hazards with spikes in the first and twelfth months. This suggests time-dependent price-setting by at least some of the producers. The spike after 12 months might be explained by seasonal demand effects, but also by the pricing season effect related to information acquisition and processing, negotiation and signing of price contracts. The revealed price adjustment pattern is at odds with the predictions of the Calvo model, a central element in many dynamic stochastic general equilibrium models, as this assumes constant frequencies of price adjustments over time. Our empirical findings instead point to a modified Calvo model where firms in some periods experience lower menu costs. Finally, the empirical findings may have implications for the effectiveness of monetary policy interventions.
The Current State of Transradial Access: A Perspective on Transradial Outcomes, Learning Curves, and Same-Day Discharge
Authors: Rymer Jennifer A. , Rao Sunil V.
Published: August 2018

The adoption of transradial access in the United States and internationally has been growing over the past few years. In the population of patients presenting with acute coronary syndromes, particularly ST-elevation myocardial infarction, transradial access has the benefit of fewer vascular and bleeding complications and lower mortality rates over transfemoral access. We will examine the current evidence supporting transradial access for several patient populations, including those patients presenting with acute coronary syndromes. We will review the literature regarding the learning curve for transradial access with new operators, as well as experienced transfemoral operators new to transradial access. Finally, we will investigate the role of transradial access in same-day discharge for stable patients undergoing percutaneous coronary intervention.
The Use of Direct Oral Anticoagulants for Prevention of Stroke and Systemic Embolic Events in East Asian Patients with Nonvalvular Atrial Fibrillation
Authors: Ma Chang-Sheng
Published: August 2018

As patients in East Asia age, the prevalence of age-related and chronic disease, including nonvalvular atrial fibrillation, may increase. Although warfarin has been the primary choice of anticoagulant for the prevention of stroke and systemic embolic events, the use of direct oral anticoagulants (DOACs) is increasing. DOACs do not require monitoring of the international normalized ratio to determine the optimal dose, and have a lower potential for food and drug interactions, improved benefit-risk profiles, and a quicker onset and offset of action relative to warfarin. The pivotal phase 3 trials for each of the DOACs – dabigatran, rivaroxaban, apixaban, and edoxaban – included at least some East Asian patients. Additionally, several clinical trials were conducted specifically for East Asian patients. This review discusses patterns and predictors of anticoagulant use in East Asian patients with nonvalvular atrial fibrillation, summarizes current guideline recommendations for East Asian patients, details the primary results demonstrating the safety and efficacy of DOACs in East Asian patients relative to non–East Asian patients, provides real-world data supporting the phase 3 testing results, and addresses the clinical profile of DOACs in East Asian populations, including patients at high risk of stroke.
The Contemporary Role of Femoral Artery Access
Authors: Shah Syed Raza , Park Ki
Published: August 2018

The scope of interventional cardiology has rapidly expanded over the last several decades. In a field where procedural treatment options for a variety of complex cardiovascular conditions have grown exponentially, the importance of procedural safety continues to come to the forefront. This is most evident in the movement toward radial access as the initial approach for operators in the cardiac catheterization laboratory. As the evidence grows for the superiority of radial access over femoral access with regard to reducing bleeding events and improving clinical outcomes, we discuss the modern approach to obtaining access, and highlight best practices.
Motivation Modulates Brain Networks in Response to Faces Varying in Race and Status: A Multivariate Approach

Previous behavioral and neuroimaging work indicates that individuals who are externally motivated to respond without racial prejudice tend not to spontaneously regulate their prejudice and prefer to focus on nonracial attributes when evaluating others. This fMRI multivariate analysis used partial least squares analysis to examine the distributed neural processing of race and a relevant but ostensibly nonracial attribute (i.e., socioeconomic status) as a function of the perceiver’s external motivation. Sixty-one white male participants (Homo sapiens) privately formed impressions of black and white male faces ascribed with high or low status. Across all conditions, greater external motivation was associated with reduced coactivation of brain regions believed to support emotion regulation (rostral anterior cingulate cortex), introspection (middle cingulate), and social cognition (temporal pole, medial prefrontal cortex). The reduced involvement of this network irrespective of target race and status suggests that external motivation is related to the participant’s overall approach to impression formation in an interracial context. The findings highlight the importance of examining network coactivation in understanding the role of external motivation in impression formation, among other interracial social processes.

Confirming the presence of a fourth species of non-native house gecko of the genus Hemidactylus Oken, 1817 (Squamata, Gekkonidae) in Colombia
Authors: Vásquez-Restrepo Juan D. , Lapwong Yingyod
Published: August 2018

The Indo-Pacific Gecko, Hemidactylus garnotii Duméril & Bibron, 1836, is a species of house gecko native to Southeast Asia and Pacific Islands. As with many of its congeners, this gecko species has been accidentally introduced to other parts of the world. In January 2018, several photographs of “H. frenatus” from Colombia posted in iNaturalist.org, were noticed to have some morphological features related to H. garnotii. This discrepancy led us to inspect museum specimens and to confirm the presence of H. garnotii for more than a decade in Colombia.

The business model for organizational diversity states that “diverse” organizations have a competitive advantage over non-“diverse organizations. These advantages arise from increased creativity,1 problem solving,2,3 decision making,4 and overall quality of results,5 among other observed outcomes. Within academia, increasing diversity benefits performance and persistence of students by reducing the deleterious effects of solo status (being the only representative of a social group)/tokenism (member of a minority social group in a given organization) and stereotype threat.
