Analysis of thermodynamics of two-fuel power unit integrated with a carbon dioxide separation plant
Authors: Kotowicz Janusz , Bartela Łukasz , Mikosz Dorota 
Published: March 2015

Abstract
The article presents the results of thermodynamic analysis of the supercritical coal-fired power plant with gross electrical output of 900 MW and a pulverized coal boiler. This unit is integrated with the absorption-based CO2 separation installation. The heat required for carrying out the desorption process, is supplied by the system with the gas turbine. Analyses were performed for two variants of the system. In the first case, in addition to the gas turbine there is an evaporator powered by exhaust gases from the gas turbine expander. The second expanded variant assumes the application of gas turbine combined cycle with heat recovery steam generator and backpressure steam turbine. The way of determining the efficiency of electricity generation and other defined indicators to assess the energy performance of the test block was showed. The size of the gas turbine system was chosen because of the need for heat for the desorption unit, taking the value of the heat demand 4 MJ/kg CO2. The analysis results obtained for the both variants of the installation with integrated CO2 separation plant were compared with the results of the analysis of the block where the separation is not conducted.
Identification of the objective function for optimization of a seasonal thermal energy storage system
Authors: Milewski Jarosław , Szabłowski Łukasz , Bujalski Wojciech 
Published: March 2015

Abstract
The article shows the proposed solution of the objective function for the seasonal thermal energy storage system. In order to develop this function the technological and economic assumptions were used. In order to select the optimal system configuration mathematical models of the main elements of the system were built. Using these models, and based on the selected design point, the simulation of the entire system for randomly generated outside temperatures was made. The proposed methodology and obtained relationships can be readily used for control purposes, constituting model predicted control (MPC).
Prediction of flow boiling heat transfer data for R134a, R600a and R290 in minichannels

Published: March 2015

Abstract
In the paper presented is the analysis of the results of calculations using a model to predict flow boiling of refrigerants such as R134a, R600a and R290. The latter two fluids were not used in the development of the model semiempirical correction. For that reason the model was verified with present experimental data. The experimental research was conducted for a full range of quality variation and a relatively wide range of mass velocity. The aim of the present study was also to test the sensitivity of developed model to a selection of the model of two-phase flow multiplier and the nonadiabatic effects. For that purpose two models have been analysed namely the one due to Muller-Steinhagen and Heck, and Friedel. In addition, the work shows the importance of taking surface tension into account in the calculation of the flow structure.

Rate and direction of changes in tree species composition of natural stands in selected forest associations in the Białowieża Forest
Authors: Paluch Rafał 
Published: March 2015

Abstract
The main aim of the study was to determine changes in the species composition and structure of natural tree stands in the Białowieża Forest (BF), which occurred in the years 1975-2012, as well as to evaluate their trends, directions and rate. The study was carried out on 121 permanent research plots (50 × 50 m), which represented the most important forest phytocenoses in BF, i.e. fresh pine-whortleberry forest Vaccinio vitisidaeae- Pinetum Sokoł. 1980, fresh mixed spruce-reed grass forest Calamagrostio-Piceetum Sokoł. 1968, oligotrophic form of hornbeam - bastard balm forest Melitti-Carpinetum Sokoł. 1976, different forms of lindenhornbeam forest: Tilio-Carpinetum Tracz. 1962, alder-ash forest Fraxino-Alnetum W. Mat. 1952 and sub-boreal spruce forest on bog moss Sphagno girgenshonii-Piceetum Polak. 1962. On the plots selected, there was measured the diameter at breast height (DBH) of all trees, as well as every tree and shrub up to 1.3 m high was counted and described with reference to species. The measurements and observations were regularly repeated every 10-15 years. The results showed that over the last period of nearly 40 years, there has increased a share of common hornbeam Carpinus betulus L. in the structure of forest stands in numerous BF associations. This tree species has expanded into different forest habitats including poor, medium fertile and wetland sites. The results obtained indicate a trend towards formation of linden-hornbeam forests in BF phytocenoses. The most evident changes were recorded in hornbeam - bastard balm forest. In natural conditions of the majority of forest associations analysed, there prevailed hornbeam trees in forest regeneration, except for the stands in fresh mixed pine forest and spruce forest on bog moss. In the latter two cases, hornbeam showed signs of its presence in the last observation period. Norway spruce (Picea abies L.) retreated into oligotrophic forest associations. In the recent decades, spruce populations have been dramatically reduced in the stands in mixed coniferous and different kinds of broadleaved forests. There have also decreased a share of light-demanding tree species, such as Scots pine (Pinus silvestris L.), pedunculate oak (Quercus robur L.) and silver birch (Betula pendula L.) in BF tree stands, including their regeneration-layer. Especially, Scots pine regeneration has not been successful. In the short period of time (about 15 years) there has been observed rapid and outsized reduction of ash Fraxinus excelsior L. populations in natural conditions of alder-ash forests. All through the last 10-15 years, there has been also observed increased rate of change in stand species composition. The trend and rate of change in stand species composition point out to a possibility of human intervention towards stimulation of natural regeneration so as to preserve valuable populations of threatened tree species in the Białowieża Forest.
Collaboration Leads to Enhanced Curriculum

Summary
Background: In 2007, we initiated a health information management (HIM) track of our biomedical informatics graduate program, and subsequent ongoing program assessment revealed a confluence of topics and courses within HIM and clinical informatics (CI) tracks. We completed a thorough comparative analysis of competencies derived from AMIA, AHIMA, and CAHIIM. Coupled with the need to streamline course offerings, the process, described in this paper allowed new opportunities for faculty collaboration, resulted in the creation of a model assessment for best practice in courses, and led to new avenues of growth within the program.
Objective: The objective of the case study is to provide others in the informatics educational community with a model for analysis of curriculum in order to improve quality of student learning.
Methods: We describe a case study where an academic informatics program realigned its course offerings to better reflect the HIM of today, and prepare for challenges of the future. Visionary leadership, intra-departmental self-analysis and alignment of the curriculum through defined mapping process reduced overlap within the CI and HIM tracks. Teaching within courses was optimized through the work of core faculty collaboration.
Results: The analysis of curriculum resulted in reduction of overlap within course curriculum. This allowed for additional and new course content to be added to existing courses.
Conclusions: Leadership fostered an environment where top-down as well as bottom-up collaborative assessment activities resulted in a model to consolidate learning and reduce unnecessary duplication within courses. A focus on curriculum integration, emphasis on course alignment and strategic consolidation of course content raised the quality of informatics education provided to students. Faculty synergy was an essential component of this redesign process. Continuous quality improvement strategy included an ongoing alignment of curriculum and competencies through a comparative analysis approach. Through these efforts, new innovation was possible.

Published: March 2015

SummaryBackground: Hospital closures are becoming increasingly common in the United States. Patients who received care at the closing hospitals must travel to different, often farther hospitals for care, and nearby remaining hospitals may have difficulty coping with a sudden influx of patients.Objectives: Our objectives are to analyze the dispersion patterns of patients from a closing hospital and to correlate that with distance from the closing hospital for three specific visit types: emergency, inpatient, and ambulatory.Methods: In this study, we used data from a health information exchange to track patients from Saint Vincent’s Medical Center, a hospital in New York City that closed in 2010, to determine where they received emergency, inpatient, and ambulatory care following the closure.Results: We found that patients went to the next nearest hospital for their emergency and inpatient care, but ambulatory encounters did not correlate with distance.Discussion: It is likely that patients followed their ambulatory providers as they transitioned to another hospital system. Additional work should be done to determine predictors of impact on nearby hospitals when another hospital in the community closes in order to better prepare for patient dispersion.Citation: Garg N, Husk G, Nguyen T, Onyile A, Echezona S, Kuperman G, Shapiro JS.

Information Ownership and Materiality in an Age of Big Data Surveillance
Authors: Hogan Mél , Shepherd Tamara 
Published: March 2015

Abstract
Can private data “havens,” localized servers, and offline infrastructure empower secure and private user control over data? Contrasting Sealand's counter-surveillance policies with the NSA's Utah Data Center mass surveillance apparatus, the authors analyze how control of the physical location of data centers shapes the possibilities of data agency and ownership. They note that to whom data belongs has become regulated asymmetrically through technological capacity rather than through socially articulated norms or deliberative legal processes. They offer a number of policy approaches to enhance the democratic potential of information stewardship, but question whether any are sufficient to subvert the power of agencies such as the NSA.

Resistance. An introduction
In the introduction of the special issue of the Journal on Crime & Culture on ‘Resistance’, the editors focus on the theoretical history of the concept of resistance in the field of Criminology. Against the background of the Birmingham School and the themes and ideas of Critical Criminology, the authors argue that new issues are rebelled against, and new styles and rituals become en vogue. The street fighting man on the barricades is no longer the obvious icon, and resistance is not per se intergenerational, interclass or a confrontation between minorities and mainstream culture. Resistance may have epidemic proportions as the Arabic Spring. Movements like Occupy or WikiLeaks operate across borders, but resistance also includes subtle transgressions within organizations.

To resist = to create? Some thoughts on the concept of resistance in cultural criminology
This article provides a theoretical analysis of the label ‘resistance’. It sets out from the premise that the notion of resistance, although it has been current in criminology for some time, is still vaguely defined. We argue that resistance is not just a negative term, but can also be seen as a positive and creative force in society. As such, the primary function of resistance is to serve as a solvent of doxa, to continuously question obviousness and common sense. In the process of resistance we distinguish three processes: invention, imitation and transformation. The third stage warrants deeper investigation within cultural criminology.
Jusqu’ici tout va bien. Jongeren en de productie van parochiale plaatsen in La Haine

Jusqu’ici tout va bien. Youth and the production of parochial places in La Haine
La Haine (Kassovitz, 1995) shows practices of resistance of youngsters in public space. Next to the traditional milieus of socialisation – at home, at school or in institutionalised leisure facilities – youngsters demand their ‘place’ in public space. In doing so, they partly privatise public space (‘parochial space’). In this article we argue that transgressive behaviour of youngsters should be conceptualised as both a side-effect of growing up and socialisation, and as resistance against adult domination, especially in public space. As such, hanging around is cause and effect of control and criminalisation.
Commodifying compliance? UK urban music and the new mediascape

Commodifying compliance? UK urban music and the new mediascape
Subcultural theory and cultural criminology have traditionally viewed ‘underground’ youth movements as providing images of deviance/resistance which the cultural industries harvest to turn a profit. The logic follows that street and sub cultures imbue products with a ‘transgressive edge’ that increases their appeal within youth markets. This paper uses the example of UK ‘grime’ music to demonstrate how this dynamic cannot be viewed as applying universally in contemporary times. Where their street orientated content is censured, many grime artistes express a desire for commercial success which would ultimately emerge through muting their rhetorical links to crime and violence and explicitly championing ‘mainstream’ values. This case is used as an empirical cue to explore the use and critique of the concept of ‘resistance’ within cultural criminology and subcultural theory. The paper problematizes commodification of resistance discourses as they apply to the rugged culture of the streets and indeed its supposed ‘oppositional’ character where disadvantaged urban youth clearly embody and practice the logic of neoliberalism. It furthermore suggests that certain critiques of cultural criminology go too far in denying any meaning to criminality and subcultural practice beyond consumer desire. Ultimately, the concept of ‘defiance’ is suggested as a useful tool to understand the norms of and behaviours of the excluded.
Verzet of collaboratie? Hoe de strijd tegen genocide kan bijdragen aan genocide
Authors: Moerland Roland

Resistance or collaboration? How the struggle against genocide can facilitate genocide.
The politization of the concept of genocide by Western states has been severely criticised, because it has led to an impunity for genocidal crimes. In certain instances however, such criticism has contributed to the dynamic of victimization, instead of resisting it. The article discusses how Professor Edward S. Herman and journalist David Peterson’s staunch criticism of the politics of genocide amounts to a brazen denial of the genocide against the Tutsi which recycles much of the extremist discourse of the former Rwandan authorities that were implicated in genocide. In this case Herman and Peterson’s resistance against the politics of genocide has profound implications, several of which the article will address.

Effects of test stress during an objective structured clinical examination
Authors: Zhang Niu , Rabatsky Ali 
Published: March 2015

Objective
The existence of test stress has been widely reported among professional students. To our knowledge, no studies exist that explore student stress response to objective structured clinical examinations. The aim of this study was to evaluate possible correlations between stress and objective structured clinical examination performance in a sample of chiropractic students.

Methods
A total of 116 students completed a 2-part questionnaire to assess test stress and the physiological symptoms and signs of stress. Heart rate, systolic blood pressure, and diastolic were measured during the physical examination laboratory class within the first 3 weeks and then again just prior to their objective structured clinical examination in week 5. Statistical tests were then performed for questionnaire data, heart rate and blood pressure differences, and correlation between the objective structured clinical examination grade and symptoms and signs.

Results
Questionnaire results showed that 5.1%–22.4% of students sometimes or often felt a certain degree of stress. More than 50% had 1 or more physiological symptoms and signs of stress. The objective structured clinical examination heart rate (75.23 ± 11.20 vs 68.16 ± 8.82, p &lt; .001), systolic blood pressure (120.43 ± 9.59 vs 114.97 ± 11.83, p &lt; .001), and diastolic blood pressure (73.00 ± 7.93 vs 69.32 ± 7.76, p &lt; .001) were significantly higher than baseline. There were also negative linear correlations between objective structured clinical examination grades and physiological symptoms and signs and between objective structured clinical examination grades and feeling statement score.

Conclusion
The results support our hypothesis that chiropractic students experience stress when performing the objective structured clinical examination and that high levels of stress had a negative impact on performance.

AbstractTo better understand the current carbon cycle and potentially detect its change in the rapidly changing Arctic Ocean, we examined sinking particles collected quasi‐continuously over a period of 7 years (2004–2011) by bottom‐tethered sediment trap moorings in the central Canada Basin. Total mass flux was very low (<100 mg m−2 d−1) at all sites and was temporally decoupled from the cycle of primary production in surface waters. Extremely low radiocarbon contents of particulate organic carbon and high aluminum contents in sinking particles reveal high contributions of resuspended sediment to total sinking particle flux in the deep Canada Basin. Station A (75°N, 150°W) in the southwest quadrant of the Canada Basin is most strongly influenced while Station C (77°N, 140°W) in the northeast quadrant is least influenced by lateral particle supply based on radiocarbon content and Al concentration. The results at Station A, where three sediment traps were deployed at different depths, imply that the most likely mode of lateral particle transport was as thick clouds of enhanced particle concentration extending well above the seafloor. At present, only 1%–2% of the low levels of new production in Canada Basin surface waters reaches the interior basin. Lateral POC supply therefore appears to be the major source of organic matter to the interior basin. However, ongoing changes to surface ocean boundary conditions may influence both lateral and vertical supply of particulate material to the deep Canada Basin.
Morphodynamics: Rivers beyond steady state
Authors: Church M. , Ferguson R. I. 
Published: March 2015

AbstractThe morphology of an alluvial river channel affects the movement of water and sediment along it, but in the longer run is shaped by those processes. This interplay has mostly been investigated empirically within the paradigm of Newtonian mechanics. In rivers, this has created an emphasis on equilibrium configurations with simple morphology and uniform steady flow. But transient adjustment, whether between equilibrium states or indefinitely, is to be expected in a world in which hydrology, sediment supply, and base level are not fixed. More fundamentally, water flows and all the phenomena that accompany them are inherently unsteady, and flows in natural channels are characteristically nonuniform. The morphodynamics of alluvial river channels is the striking consequence. In this paper, we develop the essential connection between the episodic nature of bed material transport and the production of river morphology, emphasizing the fundamental problems of sediment transport, the role of bar evolution in determining channel form, the role of riparian vegetation, and the wide range of time scales for change. As the key integrative exercise, we emphasize the importance of physics‐based modeling of morphodynamics. We note consequences that can be of benefit to society if properly understood. These include the possibility to better be able to model how varying flows drive morphodynamic change, to understand the influence of the sediments themselves on morphodynamics, and to recognize the inherent necessity for rivers that transport bed material to deform laterally. We acknowledge pioneering contributions in WRR and elsewhere that have introduced some of these themes.
