Quality metrics currently used in academic radiology departments: results of the QUALMET survey
Authors: Walker Eric A , Petscavage-Thomas Jonelle M , Fotos Joseph S , Bruno Michael A 
Published: January 2017

Objective:
We present the results of the 2015 quality metrics (QUALMET) survey, which was designed to assess the commonalities and variability of selected quality and productivity metrics currently employed by a large sample of academic radiology departments representing all regions in the USA.

Methods:
The survey of key radiology metrics was distributed in March–April of 2015 via personal e-mail to 112 academic radiology departments.

Results:
There was a 34.8% institutional response rate. We found that most academic departments of radiology commonly utilize metrics of hand hygiene, report turn around time (RTAT), relative value unit (RVU) productivity, patient satisfaction and participation in peer review. RTAT targets were found to vary widely. The implementation of radiology peer review and the variety of ways in which peer review results are used within academic radiology departments, the use of clinical decision support tools and requirements for radiologist participation in Maintenance of Certification also varied. Policies for hand hygiene and critical results communication were very similar across all institutions reporting, and most departments utilized some form of missed case/difficult case conference as part of their quality and safety programme, as well as some form of periodic radiologist performance reviews.

Conclusion:
Results of the QUALMET survey suggest many similarities in tracking and utilization of the selected quality and productivity metrics included in our survey. Use of quality indicators is not a fully standardized process among academic radiology departments.

Advances in knowledge:
This article examines the current quality and productivity metrics in academic radiology.

How Do Contract Parameters Influence the Economics of Vehicle-to-Grid?
Authors: Broneske Gerald , Wozabal David 
Published: January 2017

By modifying the charging patterns of a pool of electric vehicles (EVs), aggregators are able to provide services to the electric grid. The parameters that shape the agreement between aggregators and EV owners, such as plug-in duration and guaranteed driving range, affect the appeal of signing up with an aggregator. Our study examines how these contract parameters influence the profitability of vehicle pools. We use a bottom-up model that encompasses the entire planning problem faced by an aggregator. The model is applied to the German secondary reserve market using actual driving patterns and market data. Our results indicate that contract parameters influence EVs’ value to aggregators in surprising ways, partially contradicting findings in previous literature. In essence, high levels of plug-in durations or low levels of guaranteed driving for planned trips do not necessarily provide the highest profit. Furthermore, we find that realistic nonanticipative strategies lead to annual profits in the range of €167 to €125 per vehicle, which is in the lower range of previous studies. Our results are a starting point for a discussion about optimal contract parameters and the design of corresponding marketing strategies.

Withdrawal of ICS treatment in primary care: A practical guide
Authors: Chalmers James , Bobak Alex , Scullion Jane , Murphy Anna 
Published: January 2017

There is increasing concern over the inappropriate prescribing of inhaled corticosteroids for patients with COPD. Here the authors discuss how to step down ICS treatment without adverse effects. By James Chalmers, Alex Bobak, Jane Scullion, and Anna Murphy Inhaled corticosteroids (ICS) are frequently inappropriately prescribed for patients with COPD resulting in up to 70% of patients in current practice receiving them. ICS (prescribed as a combination inhaler with a long-acting beta2-agonist (LABA)) are primarily indicated for patients with an FEV1<50% predicted and a history of frequent exacerbations. There is a consensus that they provide no benefit for patients with preserved lung function and no history of exacerbations. Safety concerns, particularly with regard to pneumonia, osteoporosis, bruising, adrenal suppression and diabetes have been reported in ICS users. Withdrawal of ICS in these patients may therefore promote cost-effective prescribing, and reduce the risk of adverse effects. Nevertheless, in the absence of recognised national guidelines, removing a longstanding therapy from patients with COPD can be challenging. Concerns and barriers reported by clinicians include the risk that patients may subsequently exacerbate or experience a worsening of symptoms, the risk of inadvertently removing ICS from patients with a diagnosis of asthma, and the risks of adrenal insufficiency. Recent randomised controlled trials clearly demonstrate it is possible to remove ICS in a subgroup of patients with COPD and replace with bronchodilator therapies, and that such withdrawal does not result in clinically important increases in exacerbations or worsening of symptoms. In this article, we provide practical advice about when and how to withdraw ICS in patients with COPD.

Authors: Taylor Claire , Rickard Helen 
Published: January 2017

Colorectal is the third most common cancer in the UK and even when successfully treated, its effects on the patient can be complex and life-changing. Claire Taylor and Helen Rickard discuss how to manage them All patients face consequences as a result of being diagnosed and treated for cancer. These can include physical, emotional, social and/or financial factors which can occur both acutely and in the longer-term. This article focuses on the common consequences of being treated for colorectal cancer and suggests some ways these concerns can be managed holistically and effectively in general practice. In doing so, nursing can play an important role in helping individuals to live well with, and beyond, cancer.

Increased vimentin mRNA expression in MCF-7 breast cancer cell line after repeated endoxifen-treatment
Authors: Paramita Paramita , Louisa Melva , Nafrialdi Nafrialdi 
Published: January 2017

Background: Epithelial mesenchymal transition (EMT) plays a significant role in the development of cancer cell resistance to drugs. Vimentin, a type III intermediate filament protein, is a marker of EMT. Vimentin's over-expression in cancer correlates well with increased tumor growth, change in cell shape and poor prognosis. Endoxifen is an active metabolite of tamoxifen and has become a new potent agent in the treatment of breast cancer. This is a study that aimed to investigate the effect of endoxifen exposure with or without estradiol on cell viability, cell morphology and EMT progression through the analysis of vimentin mRNA expression after 4-week treatment.
Methods: Endoxifen, 100 nM or 1,000 nM, with or without beta-estradiol were given repeatedly to MCF-7 cells. Cells treated with dimethyl sulfoxide (DMSO) 0.001% were used as control. After 2- and 4-week exposure, the cells were counted, analyzed for mRNA vimentin expression, and observed for morphological changes.
Results: Compared to control, there were significant decreases in vimentin mRNA expressions in endoxifen and endoxifen+β-estradiol treated cells after 2-weeks, which then significantly increased after 4-week compared with the 2-week exposure. We found no change in morphology of MCF-7 cells.
Conclusion: Repeated exposure of endoxifen might induce EMT progression through increased expression of vimentin in MCF-7 breast cancer cell line.

Published: January 2017

Background Adolescents with hypertension are at risk of morbidity and mortality due to cardiovascular problems in later life. Hypertension may be influenced by poor quality of sleep, so early detection of hypertension and ensuring good quality of sleep in adolescence is needed.Objective To assess for a possible association between poor sleep quality and hypertension in adolescents.Methods We conducted a cross-sectional study from January to March 2013 in Mustafawiyah Boarding School, Mandailing Natal, North Sumatera. Subjects’ quality of sleep was assessed by the Pittsburgh Sleep Quality Index (PSQI) questionnaire and their systolic and diastolic blood pressures were measured. Quality of sleep was categorized as either good or poor. Blood pressure was categorized as either normotensive or hypertensive. An association between poor sleep quality and hypertension was analyzed by Chi-square test.Results Two hundred forty adolescents participated in this study, of whom 210 (87.5%) subjects were normotensive and 30 (12.5%) subjects were hypertensive. We found higher systolic blood pressure [114.9 (SD 11.7) vs. 109.5 (SD 10.5) mmHg as well as diastolic blood pressure [74 (SD 9.1) vs. 69.9 (SD 7.5) mmHg in adolescents with poor sleep quality compared to those with good sleep quality (P=0.001).Conclusion Poor sleep quality is associated with hypertension in adolescents.

Published: January 2017

This experiment was conducted to study the effect of different fertilizing and farming systems in annual medic (Medicago scutellata ‘Robinson’) on soil organic matter and nutrients status. Fertilizing systems consisted of control (no fertilizer), chemical fertilizer, biological fertilizer and integrated fertilizers (different combinations of chemical and biological fertilizing systems). The farming systems included irrigated and dry-farming systems. The experiment was conducted in two experimental sites with diverse climatic and soil conditions in Kermanshah province, Iran, during 2009 growing season. The highest amount of soil organic matter of 1.28 % was observed in integrated fertilizing system of nitrogen-fixing bacteria + phosphorus-solubilizing bacteria. Most of the nitrogen applied through chemical fertilizers was leached out of the plant access, however, application of integrated fertilizer resulted in increasing the concentration of nitrogen in soil because of its slow release and efficient utilization by plants. According to the results of this study it was concluded that the integrated fertilizing system was more successful in dry farming compared to other fertilizing systems.

Published: January 2017

Sesame collections were evaluated for quantitative floral characters and data obtained were subjected to various statistical analyses. Result showed narrow diversity in most of the quantitative floral characters with moderate variability in length of flower (2.03-3.27 cm), length of style (1.10-1.40 cm), length of capsule (2.33-2.98 cm) and number of seeds per capsule (38.67 – 57.67). Correlation study revealed significantly (p < 0.01) positive correlations for length of ovary versus length of flower (r= 0.70) and length of capsule versus length of style (r= 0.77). The first two principal components accounted for 61.59 % of which the first component had 34.13 % and the second was 27.46 %. Dendrogram divided the seventeen accessions/landraces into two major groups (A and B). Group A had only one cluster with five members whilegroup B had three clusters (Cluster II, III and IV) with seven, three and two members respectively. Each accession within a cluster could be employed as baseline parent in crossbreeding for improvement of yield in Nigerian sesame.

Published: January 2017

Green areas in cities and their ecosystem services (ES) offer residents various benefits. The range of services depends on biodiversity of a green space. The aim was to determine the relationship between biodiversity in different categories of green areas in the city and the ecosystem services, which appear in it. We made 108 relevés in the autumn and spring time, within nine categories of green areas in the Municipality of Ljubljana. In each category the range of ES was assessed based on field analysis and compared with literature assessed ecosystem services. Results showed that the category of forests differ from others. Other categories were similar to each other, in particular grassland categories. Also, a positive relationship linkage was found - more plant species mean more assessed ecosystem services in a specific green infrastructure category.

Published: January 2017

The increasing popularity of mobile device usage has ushered in many features in modern search engines that help users with various information needs. One of those needs is Knowledge Exploration, where related documents are returned in response to a user query, either directly through right-hand side knowledge panels or indirectly through navigable sections underneath individual search results. Existing knowledge exploration features have relied on a combination of Knowledge Bases and query logs.
In this paper, we propose Knowledge Carousels of two modalities, namely sideways and downwards, that facilitate exploration of IS-A and HAS-A relationships, respectively, with regard to an entity-seeking query, based on leveraging the large corpus of tables on the Web. This brings many technical challenges, including associating correct carousels with the search entity, selecting the best carousel from the candidates, and finding titles that best describe the carousel. We describe how we address these challenges and also experimentally demonstrate through user studies that our approach produces better result sets than baseline approaches.
Internal Structure of Vitrinite and Sporinite in the View of Micro-FTIR Spectroscopy Using the Example of Coal from the Seam 405 of the Upper-Silesian Coal Basin (USCB)
Authors: Komorek Joanna 
Published: January 2017

Abstract
The aim of the study was to compare the internal structure of vitrinite and sporinite obtained from coal from the seam 405. The examinations were performed with the use of infrared spectroscopy in the micro-area (micro-FTIR).
Studies have shown that vitrinite is characterized by lower content of aliphatic components and greater content of aromatic components than sporinite. Sporinite is characterized by longer and less branched aliphatic chains than vitrinite.
It was found that vitrinite internal structure is characterized by a greater relative content of aromatic than aliphatic components. The degree of condensation of aromatic rings in structure of vitrinite increases, when the coal rank rises. Studies have shown that the transformation of the vitrinite internal structure towards a structure characterized by a greater degree condensation of aromatic components proceeds at the cost of restructuring the aliphatic groups and is related to the restructuring of the aromatic systems.
The structure of sporinite is characterized by a greater participation of aliphatic bonds as compared to aromatic bonds. The relative content of the aliphatic components decreases together with increase of aromatic hydrogen functional group CHar content in the internal structure of sporinite when the coal rank rises. The aliphatic bonds in the sporinite are subject to restructuring. The aliphatic chains are getting increasingly shorter.

Equilizing of the Primary Stress State in the Rock Mass, Simulated by a Model of Layer in an Elastic-Viscous Medium
Authors: Kortas Grzegorz 
Published: January 2017

Abstract
This paper is devoted to the analysis of the stress development process in the homogeneous and non-homogeneous rock mass. The rock-mass model consists of an elastic-viscous medium containing a layer (Fig. 1) that displays distinct geomechanical strain properties. When examining the process of stress equilizing in time, the Norton-Bailey power creep law was applied in the numerical analysis. The relationship between effective stresses and time, the modulus of elasticity, Poisson’s coefficient, and creep compliance were obtained. It was demonstrated that the relationship between effective stress and time or creep compliance, for the assumed conditions in a homogeneous rock-mass, was approximated by hyperbolic functions (10 and 16). The process parameter included a certain value of creep compliance or of time at which there occurred a half-way equilizing of primary stresses. An analogous function binds effective stresses with creep compliance. Our model studies indicated a number of relationships between bulk and shear strain with time and creep compliance in the homogeneous and non-homogeneous rock mass, presented in Figs. 2-14, expressed by the functions of those specific parameters.
The relationships obtained in this work resulted from our model assumptions. However, they demonstrated the influence of the geomechanical strain properties of rocks on the process of shaping the primary stress state in the rock mass and the tendency to reduce the principal stress differences in time. Our research results suggested the necessity to simulate the primary stress state as an initial condition of the geomechanical numerical analysis concerning the rock-mass behaviour showing rheological properties.

Published: January 2017

Abstract
Perspectives of development of control system dedicated for areas threatened by methane and/or coal dust explosion hazard are presented. Development of self-powered sensors, dedicated for operation in wireless network is one of the development directions. Such a solution will complement typical control systems and it can be used in the places, where there is no possibility of using the typical sensors, in close vicinity to the machine – due to lack of wired connection. General concept of the self-powered sensors with use of two methods of power supply – piezoelectric energy harvester and thermoelectric generator, is given. Perspective of using the methods of artificial intelligence in automatic configuration of sensors network is suggested.

Published: January 2017

Abstract
Method of the influence of assessment of longwall effective working time onto obtained mining output, has been discussed in the present study.
Mean flow rate of the winning stream being also considered as directional factor of linear function describing relation between daily output and effective mining in the longwall face, has been determined. Such relation – presented also graphically in form of the diagram – determines significance and influence of the effective working time onto obtained mining output. This relation should be considered as motivation in particular for supervisory personnel, as it shows advantages resulting from elongation of this time, as well as it shows possible loses of the daily output in a case, when the effective working time in given longwall face was shortened.
A Game of Time: Time Travel, Video Game and Cinema in the Era of Algorithm
Authors: Liu Xiao 
Published: January 2017

Abstract
How do we experience time in an era of digital, networked communication? What if time becomes an algorithmic database that provides random accesses and entries to different moments in the past or the future? This essay focuses on a 2009 Chinese film, Lee’s Adventures, to explore the intricate interrelations between digital media and the representability of time. The film features a young urban professional named Lee, who is frenetically obsessed with playing a video game in order to travel to a different time. The film constantly highlights a suffocating, efficiency-centered corporate time that Lee has to endure as a petty clerk in a cold, glass-surfaced office building. The video game is taken by him as a “time machine” to escape from the homogenous, hollow present. Yet ironically, although the video game becomes a vehicle for Lee to travel to a different time, his access is structured by the algorithmic database of the game. Developing from an analysis of the algorithmic aesthetic of the film, I argue that the ideological functions of the index of analog cinema are now taken over by algorithm, which provides a new structure to manage the contingent. Tracing this tension between the determinacy and the play inherent in the standardization of time since the early modern period, this essay in the end asks how digital media redefine cinema’s role in restructuring time.
