The Question of Deployment Length in Peacekeeping Missions
Authors: Nový Marek
Published: December 2015

From research reports cited in this article, the period of six months seems to be suitable time for the deployment abroad. A soldier should not be redeployed for at least one year, following his previous mission. The majority of soldiers cope with deployments well and without any psychopathology. Most reported mental problems are alcohol misuse, followed by posttraumatic stress disorder (PTSD) and by the depression. Alcohol seems be even the higher risk for soldiers less exposed to combat stressors (e.g. fire), but more to chronic stressors (boredom, isolation, helplessness) than PTSD for a soldier in action. Therefore pre-deployment training of our soldiers should be more devoted to mental health aspects, starting with alcohol overuse.
La souffrance au travail
Authors: Foucart Jean
Published: December 2015

La souffrance relève de l’insupportable. Les analyses en sociologie et en psychodynamique du travail opposent, dans une tentative d’explication, les facteurs macrosociaux à la dimension microsociale. Si souffrance au travail il y a, la question qui se pose est « pourquoi et comment ça tient ? ». Ne faut-il pas faire intervenir un troisième terme au niveau de l’explication ? Des concepts tels ceux d’espace intermédiaire ou de jeu prendront toute leur importance.
Pour une formation interprofessionnelle englobant la santé et les services sociaux. Quelques leçons du Royaume-Uni
Authors: Storrie Tom
Published: December 2015

En raison de la complexification du monde professionnel, les champs d’expertise se démarquent les uns des autres et ils tendent à se cloisonner et à se hiérarchiser. C’est un moyen de contrôle des savoirs qui se renouvellent sans cesse ; il a pour effet d’interdire toute vision holistique. Les usagers des services médicaux et sociaux risquent de recevoir des soins spécialisés fournis par des professionnels entretenant peu de relations entre eux. Les systèmes de communication entre les différents secteurs et services dysfonctionnent souvent, avec des conséquences désastreuses. En dépit de multiples réformes bien intentionnées, des services formellement dédiés au maintien du bien-être des personnes et des populations sont incapables de se coordonner régulièrement et de répondre convenablement aux urgences des usagers. Une formation interprofessionnelle pourrait être un remède.
Création de soi et santé spirituelle : le rôle subtil des arts
Authors: Dallet Sylvie
Published: December 2015

La santé est une expression fondamentale de la personne, tant du point de vue personnel qu’environnemental. La sophistication contemporaine des outils de la santé ne fait pas disparaître la métamorphose subtile appelée la création de soi. La médecine est un art qui puise sa vitalité aux racines du vivant : la création de soi est un exercice lent, spécifique à chacun ; elle se nourrit, comme une plante, des soins qu’elle reçoit et des obstacles qu’elle apprivoise. L’environnement ne fonctionne pas autrement : négligé ou violenté, il périclite et contamine dans son dépérissement les êtres qui le peuplent. La question de la santé interroge les philosophies de terrain et de respect de la différence. L’attention au malade favorise la guérison de la maladie, dans une dialectique qui fait intervenir le respect de la personne et la qualité des lieux qui l’accueillent.

L’épreuve(s) constitue un élément de l’expérience, mais à quelle(s) condition(s), notamment au regard de la Validation des acquis de l’expérience (VAE) ? L’intention est d’aborder la question des usages et du concept d’épreuve(s) autant que de la mise à l’épreuve(s) dans le champ de la VAE, afin de mettre en exergue la pluralité d’une utilisation caractéristique d’une mobilité conceptuelle. Dans une perspective épistémologique, l’épreuve est d’abord pensée quels que soient les contextes et les objets, puis elle est envisagée en prenant appui sur des faits et des réalités analysés en référence aux représentations, aux pratiques, aux postures, aux contextes relevant de la VAE.

Panel sequencing is a practical option in genetic diagnosis. Enrichment and library preparation steps are critical in the diagnostic setting. In order to test the value of HaloPlex technology in diagnosis, we designed a custom oncogenetic panel including 62 genes. The procedure was tested on a training set of 71 controls and then blindly validated on 48 consecutive hereditary breast/ovarian cancer (HBOC) patients tested negative for BRCA1/2 mutation. Libraries were sequenced on HiSeq2500 and data were analysed with our academic bioinformatics pipeline. Point mutations were detected using Varscan2, median size indels were detected using Pindel and large genomic rearrangements (LGR) were detected by DESeq. Proper coverage was obtained. However, highly variable read depth was observed within genes. Excluding pseudogene analysis, all point mutations were detected on the training set. All indels were also detected using Pindel. On the other hand, DESeq allowed LGR detection but with poor specificity, preventing its use in diagnostics. Mutations were detected in 8% of BRCA1/2-negative HBOC cases. HaloPlex technology appears to be an efficient and promising solution for gene panel diagnostics. Data analysis remains a major challenge and geneticists should enhance their bioinformatics knowledge in order to ensure good quality diagnostic results.
Temperatura de color correlacionada de la luz natural: análisis dinámico en espacios interiores
Authors: Monteoliva J. M. , Villalba A. , Pattini A.
Published: December 2015

Actualmente los estudios de la iluminación natural focalizan en la amabilidad visual del espacio. Esta nueva tendencia surge de la necesidad de profesionales e investigadores de definir indicadores de la calidad de la iluminación natural. Uno de ellos es la temperatura de color correlacionada (TCC). En este trabajo, se propone analizar la influencia de la orientación de las ventanas y sus sistemas de sombreado en la percepción de color del ambiente (TCC). Para ello se propone una metodología de caracterización dinámica (espacial y temporal) de la TCC de la fuente luz natural. El análisis se desarrolló en un modelo a escala de un espacio interior, bajo condiciones de cielo claro. Los resultados han evidenciado la importancia de la orientación de la ventana en la TCC de un espacio, obteniendo variaciones de hasta el 50 %. De manera complementaria, se detecta la capacidad de modificar la TCC de los ambientes interiores que poseen las superficies vidriadas y los dispositivos de control solar.
La bóveda anular del Palacio de Carlos V en Granada. Hipótesis constructiva
Authors: Líndez B. , Rodríguez M.
Published: December 2015

La bóveda anular de perfil carpanel del cortile del palacio de Carlos V es un sistema estructural mecánicamente autoestable una vez finalizada la construcción. De tal modo que los empujes hacia el exterior se equilibran por el peso de la masa construida perimetralmente, mientras que los empujes hacia el interior, son absorbidos por un anillo de dovelas que conforma un arco plano apoyado sobre columnas, en el que actúa un sistema de fuerzas de resultante nula. Por el contrario, durante el proceso constructivo la estructura es inestable. Dada la complejidad constructiva, resulta aún más intrigante desentrañar cuál pudo ser el proceso de ejecución, tanto por la excelencia en la factura estereométrica como por la perfección geométrica lograda. Con este trabajo proponemos una hipótesis para el procedimiento constructivo que se ajuste al principio de economía de medios, orden racional de los trabajos, seguridad del proceso y excelencia de resultados.
Eficiencia isoterma de los modelos de ventilación exterior en patios de edificios residenciales. Estudio de casos
Authors: Padilla-Marcos M. A. , Feijó-Muñoz J. , Meiss A.
Published: December 2015

Muchos edificios han sido diseñados y construidos con patios interiores para satisfacer exigencias de habitabilidad, ya que estos espacios surten de luz y aire a los locales interiores. Sin embargo, la calidad del aire confinado en muchos de ellos es insalubre para el uso humano debido a la mermada capacidad que tienen para renovar su aire. El propósito del estudio es catalogar diferentes modelos de patio interior en edificios aislados, en condiciones isotermas, según sus dimensiones. El objetivo consiste en cuantificar la eficiencia en la renovación del aire en cada modelo y analizar la influencia de sus dimensiones en unas condiciones externas controladas. Adicionalmente, se comparan las normativas vigentes en España con los resultados así obtenidos. Como conclusión se determina la razón de cómo dicha eficiencia de la ventilación de patios interiores de los edificios desciende en función de su diseño.
Eficacia de los criterios de identificación del hormigón en la normativa europea (EN 206) y la reglamentación española (EHE-08)
Authors: Revuelta D. , Carballosa P. , García Calvo J. L.
Published: December 2015

La normativa europea y la reglamentación española establecen una serie de criterios de conformidad y aceptación para el hormigón, así como para la identificación del producto servido. La eficacia de los primeros ha sido suficientemente estudiada mediante el análisis de las Curvas Operativas de Control, que proporcionan la probabilidad de aceptación o rechazo de hormigones conformes. Sin embargo no es posible encontrar en la bibliografía trabajos similares sobre la eficacia de los criterios de identificación, a pesar de la importancia que tienen en la toma de decisiones para el fabricante, el legislador y el consumidor. En este trabajo los autores, empleando la simulación de Monte Carlo, han investigado la eficacia de los criterios de identificación europeos y españoles trazando las curvas de probabilidad de identificación de un hormigón no conforme con lo solicitado, y de la probabilidad de rechazo de un hormigón conforme al aplicar estos criterios.

Authors: S Chetan , Seshadri H S , Lokesha V
Published: December 2015

In the digital world of medical transcription involving various dimensions of processes, detecting the edge of a standard medical image for clinical research/diagnosis, telemedicine and other applicative purposes requires various efficient and effective methodologies to address the needs of the processes. Among these various meta-heuristics, as the size of the problem tends to increase along with time, the processes and their elemental techniques, proven to have been providing viable solutions appeals for reserve management and lesser computation times, with the efficiency of such algorithms and algorithmic operations to be enhanced at suitable levels of abstraction.

In this paper we propose an effective topological algorithm, which inhibits the characteristic features of high performance parallel enumeration in such heterogeneous computation environments. The proposed scheduler in the defined topological algorithm takes into consideration the metrics generated by As Built Critical Path (ABCP) - A hybrid methodological process. These metrics are re-initialized and processed to address the management of resources and the realization of search space. We also propose a methodology for shared memory access by the ants to perform parallel computation and as well implement the optimization factor in detecting the edge. An in-depth analysis with respect to the Speedup factor and the Execution time metrics are analyzed for various scenarios under consideration. The differentiations are evaluated and plotted for further futuristic analysis

Published: December 2015

The transmission of a suitably compressed image over a bandwidth, over long distances, gives rise towards a new era in the field of information technology. A gradual increase in this appending scenic application, involving the transfer of the images securely over the Ethernet has become an increasingly important aspect to be addressed during thou phenomenon, especially in the transfer of the digital medical images vividly, encapsulated with abundant information related to these images. The compressed medical images of the DICOM format contain certain amount of confidential data, pertaining to a clinical research or to an individual, and the confidentiality of the same has to be preserved from various security threats and eves-dropping. With a widespread applications among various multimedia applicative systems, telemedicine, medical imaging, military and certain safety-critical applications, inter-net and intra-net communicative applications, etc, a reliable transfer of suitable information, efficiently & securely is considered as one of the revolutionary aims in today’s communication technology and visual cryptographic methodologies. Real-time applications as such detailed above majorly is concerned with the security measures and many algorithms have been developed as a proof for various visual cryptographic methodologies.

In this paper we propose an efficient and a reliable visual cryptographic methodology which focuses on the encryption and decryption of the two-dimensional DICOM standard compressed medical image, effectively.

This paper discusses an efficient design of 192 bit encoder using AES Rijndael Algorithm with the decomposition of an image into square image size blocks and the image blocks are shuffled using 2D CAT map.

The shuffling of the image blocks/pixels employs a Logistic map of these image pixels coupled with 2D mapping of the pixels of the DICOM standard medical image, generated randomly, being the control parameter thereby creating a confusion between the cipher and the plain image, gradually increasing the resistive factor against the significant attacks. This paper proposes various analytical metrics such as correlation analysis,

entropy analysis, homogeneity analysis, energy analysis, contrast and mean of absolute deviation analysis, to evaluate the proposed algorithm, and their suitability in image encryption applications.

Application of the Cosine Gray Model Based on System Cloud in the Forecast of Higher Education Scale
Authors: Ge Chao , Li Cun
Published: December 2015

The scale of higher education is an essential link in the process of the formulation of education planning and reasonable allocation of teaching resources. At the same time, it also provides the required basis and support for the government to formulate educational planning and policy. The scale of higher education development is influenced not only by the level of economic development and industrial structure, but also by the total population and the living standards of residents. We take these elements as the influence factors, which contain noise information. Because the scale of higher education and its impact factors have complex nonlinear relationship, the traditional forecasting method cannot describe their changing trends, which leads to the low accuracy of prediction. In order to solve the above problems, this paper bases on the traditional GM (1,1) model to judge the number of students in the future, and uses the weakening buffer operator to amend the historical data. Secondly, this paper analyzes the structure of the system cloud gray forecasting model, and demonstrates its integral generation principle. We propose a new method for the cosine gray forecasting model which is based on the system cloud SCOS-GM (1, 1), and prove the effectiveness of SCOS-GM (1, 1) model by the residual test.

Finally, the SCOS-GM (1, 1) model is utilized to predict the scale of higher education in China during the period of 2012-2014. The results show that the scale of higher education will demonstrate a gradual upward trend in the next few years.

Skrifkritiese opstandingsperspektiewe – beoordeel vanuit die gereformeerde teologie
Authors: Coetzee Carel , Smith Stephan
Published: December 2015

Hierdie artikel ondersoek die aard en omvang van skrifkritiese opstandingsperspektiewe binne die Suid-Afrikaanse teologie. Spesifieke klem word op die konsekwensies gelê wat skrifkritiese opstandingsperspektiewe vir die kernleerstukke van die Christelike geloof inhou. Verdere konsekwensies raak die hart van die individu se daaglikse geloofslewe en die praktyk van die kerk. Ten einde hierdie doel te bereik, word enkele skrifkritiese opstandingsperspektiewe kortliks gestel. Standpuntstelling word deur ’n beoordeling van elke standpunt vanuit ’n skrifverantwoorde teologie gevolg. Die standpunt word gestel dat skrifkritiese teoloë dikwels die ryke betekenis van Christus se opstanding ontken of onderbeklemtoon. Die navorsing vir hierdie artikel het verder getoon dat skrifkritiese opstandingsperspektiewe verreikende negatiewe konsekwensies vir ’n skrifverantwoorde teologie inhou. Die gevolgtrekking is dat skrifkritiese opstandingsperspektiewe onversoenbaar met die tradisioneel-reformatoriese leer van die Christologie is.This article investigates the nature and extent of scripture-critical views of the resurrectioni n the context of South African theology. Special attention is given to the consequences that a scripture-critical view of the resurrection has on the core doctrines of reformed theology. Further consequences also affect the day-to-day faith of believers and the mission and effectiveness of the church. In order to conclude this investigation a number of scripturecritical views of the resurrection are critically investigated and evaluated from the perspective of the paradigm of reformed Dogmatics. Research has proven that scripture-critical scholars of theology displace or undervalue the impactful meaning of Christ’s resurrection. Scripturecritical views of the resurrection have numerous negative consequences for the traditional doctrines of reformed theology. This article has determined that a scripture-critical view of the resurrection is not reconcilable with the traditional reformed doctrine of Christology.
A smart phone based gait monitor system
Authors: Qin Dong , Huang Ming-Chun
Published: December 2015

Gait is a person’s manner of walking. Analysis of gait can be used in many areas like healthcare, therapy, sports training and characteristic recognition. The goal of this paper is to present a smart phone based system to collect and calculate gait parameters. These parameters which consists of steps, step length, velocity, cadence, motion intensity and walking regularity were collected by the inertial sensor in the smartphone. A prototype of gait parameter collection and visualization system has been built to collect accelerometer data from the smartphone, providing a reliable algorithm to calculate several gait parameters closely related to walking activity. The system also contains a fall detection function. Once the user suffers from fall, an alarm message will be send to another. Experiment has been done on 4 subjects for testing the stability and accuracy of the system. The experiment result has been compared with the real data. It shows a high accuracy and reliability for counting steps (error<5.47%) and walking duration (error<4.55%). Based on the gait monitor system, an anomaly data detection method is presented. Four independent gait parameters (cadence and motion intensity in three axis) are chosen from previous results during normal activity and their mean and standard deviation are calculated individually. If the latest data deviate from the normal activity model too far, this data is defined as an abnormal event.

Authors: Hofer Thomas , Schumacher Michael , Bromuri Stefano
Published: December 2015

In the past years the progress on the mobile market has made possible an advancement in terms of telemedicine systems and definition of systems for monitoring chronic illnesses. The distribution of mobile devices in developed countries is increasing. Many of these devices are equipped with wireless standards including Bluetooth and the amount of sold Smartphones is constantly increasing. Our approach is oriented towards this market, using existing devices to enable in-home patient monitoring and even further to ubiquitious monitoring. The idea is to increase the quality of care, reduce costs and gather medical grade data, especially vital signs, with a resolution of minutes or even less, which is nowadays only possible in an ICU (Intensive Care Units). In this paper we will present the COMPASS personal health system (PHS) platform, and how this platform enables Android devices to collect, analyze and send sensor data to an observation storage by means of interoperability standards. Furthermore, we will also present how this data can be compressed using advanced compressed sensing techniques and how to optimize these techniques with genetic algorithms to improve the RMSE of the reconstructed signal after compression. We also produce a preliminary evaluation of the algorithm against the state of the art algorithms for compressed sensing.
Haptic Feedback in Motor Hand Virtual Therapy Increases Precision and Generates Less Mental Workload
Authors: Ramírez-Fernández Cristina , Morán Alberto L. , García-Canseco Eloísa
Published: December 2015

In this work we show that haptic feedback in upper limb motor therapy improves performance and generates a lower mental workload. To demonstrate this, two groups of participants (healthy adults and elders with hand motor problems) used a low-cost haptic device (Novint Falcon) and a non-robotic device (Leap Motion Controller). Participants conducted the same rehabilitation task by using a non-immersive virtual environment. Results show significant differences for all participants regarding precision on the use of the haptic feedback device. Additionally, participants in the older adult group demonstrated a lower mental workload while using the haptic device (Novint Falcon). Finally, qualitative results show that participants preferred to conduct their therapy exercises by using the haptic device, as they found it more useful, easier to use and easier to learn.
Molecular Detection and Clinical Implications of HTLV-1 Infections among Antiretroviral Therapy-Naïve HIV-1-Infected Individuals in Abuja, Nigeria
Authors: Nasir Idris Abdullahi , Ahmad Abdurrahman Elfulaty , Emeribe Anthony Uchenna , Shehu Muhammad Sagir , Medugu Jessy Thomas , Babayo Adamu
Published: December 2015

Background

Individuals with human T-cell lymphotrophic virus type-1 (HTLV-1)/HIV-1 coinfection have been demonstrated to undergo CD4+ lymphocytosis even in the face of immunodeficiency and increased vulnerability to opportunistic pathogens that can lead to poor prognosis.

Objective

This study investigated the prevalence as well as the effects of HIV-1/HTLV-1 coinfection on CD4+ cell counts, routine hematology, and biochemical parameters of study participants.

Materials and Methods

This prospective cross-sectional study involved 184 blood samples collected from HIV-1-seropositive individuals attending HIV-special clinic of the University of Abuja Teaching Hospital, Gwagwalada, Nigeria. These samples were analyzed for anti-HTLV-1/2 IgM antibodies using enzyme-linked immunosorbent assay, CD4+ cell counts, and some routine hematological and biochemical parameters. All samples were also tested for HTLV-1 provirus DNA using real-time polymerase chain reaction (PCR) assay.

Results

Of the 184 subjects studied, 9 (4.9%) were anti-HTLV-1/2 IgM seropositive; however, upon real-time PCR testing, 12 (6.5%) had detectable HTLV-1 provirus DNA. The CD4+ cell count was significantly high in HTLV-1-positive (742 ± 40.2) subjects compared to their HTLV-1-negative (380 ± 28.5) counterpart ( P-value = 0.025). However, there was no significant association between HTLV-1 positivity with other hematology and biochemical parameters studied ( P > 0.05).

Conclusion

All subjects (100%) who were HTLV-1/HIV-1-coinfected had normal CD4+ counts. This gives contrasting finding on the true extent of immunodeficiency of subjects. So it is suggested to be very careful in using only CD4+ counts to monitor disease progression and as indicators for antiretroviral therapy (ART) in resource-limited settings. In such conditions, there may be a need to test for HTLV-1 alongside HIV viral loads in order to begin appropriate ART regimens that contain both pathogens.

Authors: Schwartz Yifat , Averbuch Sara , Katz Noomi , Sagiv Aliza
Published: December 2015

The Functional Loewenstein Occupational Therapy Cognitive Assessment (FLOTCA) was developed to assess integrative higher cognitive abilities in people with traumatic brain injury (TBI). The FLOTCA measures performance on three tasks: navigating on a map, organizing a toolbox, and planning a daily schedule. This study assessed the psychometric properties of the FLOTCA with a sample of 25 participants with TBI ages 18–49 and 25 matched healthy participants. The FLOTCA showed high interrater reliability (intraclass correlation = .996) and internal consistency reliability for the total score (α = .82). Construct validity was supported for the total score, t (48) = −5.48, d = 1.52, and the separate tasks. Moderate ecological validity was obtained with the combined FIM™ and Functional Assessment Measure, r (19) = .44, p < .05. The results indicate that the FLOTCA can be used to assess higher cognitive abilities in functioning and can serve as the basis for intervention planning.
Rapid growth in nitrogen dioxide pollution over Western China, 2005–2013
Authors: Cui Y.-Z. , Lin J.-T. , Song C. , Liu M.-Y. , Yan Y.-Y. , Xu Y. , Huang B.
Published: December 2015

Abstract. Western China has experienced rapid industrialization and urbanization since the implementation of the National Western Development Strategies (the "Go West" movement) in 1999. This transition has affected the spatial and temporal characteristics of nitrogen dioxide (NO2) pollution. In this study, we analyze the trends and variability of tropospheric NO2 vertical column densities (VCDs) from 2005 to 2013 over Western China, based on a wavelet analysis on monthly mean NO2 data derived from the Ozone Monitoring Instrument (OMI) measurements. We focus on the anthropogenic NO2 by subtracting region-specific "background" values dominated by natural sources. We find significant NO2 growth over Western China between 2005 and 2013 (8.6 ± 0.9 % yr−1 on average, relative to 2005), with the largest increments (15 % yr−1 or more) over parts of several city clusters. The NO2 pollution in most provincial regions rose rapidly from 2005 to 2011 but stabilized or declined afterwards. The NO2 trends were driven mainly by changes in anthropogenic emissions, as confirmed by a nested GEOS-Chem model simulation and a comparison with Chinese official emission statistics. The rate of NO2 growth during 2005–2013 reaches 11.3 ± 1.0 % yr−1 over Northwestern China, exceeding the rates over Southwestern China (5.9 ± 0.6 % yr−1) and the three well-known polluted regions in the east (5.3 ± 0.8 % yr−1 over Beijing–Tianjin–Hebei, 4.0 ± 0.6 % yr−1} over the Yangtze River Delta, and −3.3 ± 0.3 % yr−1 over the Pearl River Delta). Additional socioeconomic analyses suggest that the rapid NO2 growth in Northwestern China is likely related to the fast developing resource- and pollution-intensive industries along with the "Go West" movement as well as relatively weak emission controls. Further efforts should be made to alleviate NOx pollution to achieve sustainable development in Western China.

Abstract. Fine carbonaceous aerosols (CAs) is the key factor influencing the currently filthy air in megacities of China, yet seldom study simultaneously focuses on the origins of different CAs species using specific and powerful source tracers. Here, we present a detailed source apportionment for various CAs fractions, including organic carbon (OC), water-soluble OC (WSOC), water-insoluble OC (WIOC), elemental carbon (EC) and secondary OC (SOC) in the largest cities of North (Beijing, BJ) and South China (Guangzhou, GZ), respectively, using the measurements of radiocarbon and anhydrosugars. Results show that non-fossil fuel sources such as biomass burning and biogenic emission make a significant contribution to the total CAs in Chinese megacities: 56 ± 4 % in BJ and 46 ± 5 % in GZ, respectively. The relative contributions of primary fossil carbon from coal and liquid petroleum combustions, primary non-fossil carbon and secondary organic carbon (SOC) to total carbon are 19, 28 and 54 % in BJ, and 40, 15 and 46 % in GZ, respectively. Non-fossil fuel sources account for 52 % in BJ and 71 % in GZ of SOC, respectively. These results suggest that biomass burning has a greater influence on regional particulate air pollution in North China than in South China. We observed an unabridged haze bloom–decay process in South China, which illustrates that both primary and secondary matter from fossil sources played a key role in the blooming phase of the pollution episode, while haze phase is predominantly driven by fossil-derived secondary organic matter and nitrate.

Abstract. Complex oceanic circulation and air–sea interaction make the eastern tropical Pacific Ocean (ETPO) a highly variable source of CO2 to the atmosphere. Although the scientific community have amassed 70 000 surface fugacities of carbon dioxide (fCO2) data points within the ETPO region over the past 25 years, the spatial and temporal resolution of this data set is insufficient to fully quantify the seasonal to interannual variability of the region, a region where fCO2 has been observed to fluctuate by > 300 μatm. Upwelling and rainfall events dominate the surface physical and chemical characteristics of the ETPO, with both yielding unique signatures in sea surface temperature and salinity. Thus, we explore the potential of using a statistical description of fCO2 within sea-surface salinity–temperature space. These SSS/SST relationships are based on in situ surface ocean CO2 atlas (SOCAT) data collected within the ETPO. This statistical description is then applied to high-resolution (0.25°) Soil Moisture and Ocean Salinity (SMOS) sea surface salinity (SSS) and Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) sea surface temperature (SST) in order to compute regional fCO2. As a result, we are able to resolve fCO2 at sufficiently high resolution to elucidate the influence that various physical processes have on the fCO2 of the surface ETPO. Normalised (to 2014) oceanic fCO2 between July 2010 and June 2014 within the entire ETPO was 39 (±10.7) μatm supersaturated with respect to 2014 atmospheric partial pressures, and featured a CO2 outgassing of 1.51 (±0.41) mmol m−2 d−1. Values of fCO2 within the ETPO were found to be broadly split between the Gulf of Panama region and the rest of the tropical eastern Pacific Ocean. The northwest, central and offshore regions were supersaturated, with wintertime wind-jet-driven upwelling found to constitute the first-order control on fCO2 values. This contrasts with the southeastern/Gulf of Panama region, where heavy rainfall combined with rapid stratification of the upper water column act to dilute dissolved inorganic carbon, and yield fCO2 values undersaturated with respect to atmospheric fugacities of CO2.

Abstract. Accurate projections of marine particle export production (EP) are crucial for predicting the response of the marine carbon cycle to climate change, yet models show a wide range in both global EP and their responses to climate change. This is, in part, due to EP being the net result of a series of processes, starting with net primary production (NPP) in the sunlit upper ocean, followed by the formation of particulate organic matter and the subsequent sinking and remineralization of these particles, with each of these processes responding differently to changes in environmental conditions. Here, we compare future projections in EP over the 21st century, generated by four marine ecosystem models under IPCC's high emission scenario RCP8.5, and determine the processes driving these changes. The models simulate small to modest decreases in global EP between −1 and −12 %. Models differ greatly with regard to the drivers causing these changes. Among them, the formation of particles is the most uncertain process with models not agreeing on either magnitude or the direction of change. The removal of the sinking particles by remineralization is simulated to increase in the low and intermediate latitudes in three models, driven by either warming-induced increases in remineralization or slower particle sinking, and show insignificant changes in the remaining model. Changes in ecosystem structure, particularly the relative role of diatoms matters as well, as diatoms produce larger and denser particles that sink faster and are partly protected from remineralization. Also this controlling factor is afflicted with high uncertainties, particularly since the models differ already substantially with regard to both the initial (present-day) distribution of diatoms (between 11–94 % in the Southern Ocean) and the diatom contribution to particle formation (0.6–3.8 times lower/higher than their contribution to biomass). As a consequence, changes in diatom concentration are a strong driver for EP changes in some models but of low significance in others. Observational and experimental constraints on ecosystem structure and how the fixed carbon is routed through the ecosystem to produce export production are urgently needed in order to improve current generation ecosystem models and their ability to project future changes.

Abstract. During the period from approximately 150 to 35 million years ago, the Cretaceous–Paleocene–Eocene (CPE), the Earth was in a "greenhouse" state with little or no ice at either pole. It was also a period of considerable global change, from the warmest periods of the mid Cretaceous, to the threshold of icehouse conditions at the end of the Eocene. However, the relative contribution of palaeogeographic change, solar change, and carbon cycle change to these climatic variations is unknown. Here, making use of recent advances in computing power, and a set of unique palaeogeographic maps, we carry out an ensemble of 19 General Circulation Model simulations covering this period, one simulation per stratigraphic stage. By maintaining atmospheric CO2 concentration constant across the simulations, we are able to identify the contribution from palaeogeographic and solar forcing to global change across the CPE, and explore the underlying mechanisms. We find that global mean surface temperature is remarkably constant across the simulations, resulting from a cancellation of opposing trends from solar and paleogeographic change. However, there are significant modelled variations on a regional scale. The stratigraphic stage–stage transitions which exhibit greatest climatic change are associated with transitions in the mode of ocean circulation, themselves often associated with changes in ocean gateways, and amplified by feedbacks related to emissivity and albedo. Our results also have implications for the interpretation of single-site palaeo proxy records. In particular, our results allow the non-CO2 (i.e. palaeogeographic and solar constant) components of proxy records to be removed, leaving a more global component associated with carbon cycle change. This "adjustment factor" is illustrated for 7 key sites in the CPE, and applied to proxy data from Falkland Plateau, and we provide data so that similar adjustments can be made to any site and for any time period within the CPE.

Abstract. It is the purpose of this paper to document the NCAR global model topography generation software for unstructured grids (NCAR_Topo (v1.0)). Given a model grid, the software computes the fraction of the grid box covered by land, the grid-box mean elevation (deviation from a geoid that defines nominal sea level surface), and associated sub-grid-scale variances commonly used for gravity wave and turbulent mountain stress parameterizations. The software supports regular latitude–longitude grids as well as unstructured grids, e.g., icosahedral, Voronoi, cubed-sphere and variable-resolution grids.

Abstract. In today's world, the necessity for spatial data for various organizations is becoming so crucial that many of these organizations have begun to produce spatial data for that purpose. In some circumstances, the need to obtain real time integrated data requires sustainable mechanism to process real-time integration. Case in point, the disater management situations that requires obtaining real time data from various sources of information. One of the problematic challenges in the mentioned situation is the high degree of heterogeneity between different organizations data. To solve this issue, we introduce an ontology-based method to provide sharing and integration capabilities for the existing databases. In addition to resolving semantic heterogeneity, better access to information is also provided by our proposed method. Our approach is consisted of three steps, the first step is identification of the object in a relational database, then the semantic relationships between them are modelled and subsequently, the ontology of each database is created. In a second step, the relative ontology will be inserted into the database and the relationship of each class of ontology will be inserted into the new created column in database tables. Last step is consisted of a platform based on service-oriented architecture, which allows integration of data. This is done by using the concept of ontology mapping. The proposed approach, in addition to being fast and low cost, makes the process of data integration easy and the data remains unchanged and thus takes advantage of the legacy application provided.
