Production of biodiesel from Algae in selected Mediterranean Countries

The potential of producing bio-fuel from microalgae has been recognized as an alternative to fossil fuels, especially under the form of liquid fuel (diesel, ethanol), which can be used in the transport sector. The use of microalgae as a biomass resource for production of biodiesel has drawn a lot of attention from researchers, governments and the private sector. To foster the development of microalgae as alternative fuel, the MED-ALGAE project will contribute to the establishment of a new value chain for the production of renewable energy based on microalgae which can secure sufficient quantity and quality of biodiesel. Microalgae by-products and related new business opportunities will also be identified by the project.
The Slurrying Properties of Coal Water Slurries Containing Raw Sewage Sludge

Municipal sewage sludge always includes considerable amount of water, noxious substances, and varying chemical compositions; therefore, sludge utilization is imposed. Coal-sludge slurry (CSS), which is made by blending sewage sludge with coal, water, and additives, is being identified as a new and effective sludge utilization technology. The main objectives of the present investigation are research on the slurrying, rheology, and stability properties of five CSSs, and determine the influence of sludge type, sludge mixing proportion (α), temperature, and shear rate on the slurrying properties that play a critical role in CSS technology. Results showed that (i) the maximum solids loading (MSL) dropped sharply with the rise of α, ranging from 55.22% to 59.41% in the α = 15% case, compared to 69.16% in the α = 0 case; and (ii) the apparent viscosity dropped as the temperature rose from 20 °C to 50 °C, in an approximate linear correlation. All CSSs exhibited a pseudo-plastic rheology, and increasing ω and α re...
Metal pollution status in Zhelin Bay surface sediments inferred from a sequential extraction technique, South China Sea

Surface sediments collected from Zhelin Bay, the largest mariculture base of eastern Guangdong Province, were analyzed for total metal concentrations and chemical speciation. The results demonstrated that the average total concentration (mg/kg) ranges were 36.7-65.8 (Pb), 53.8-98.8 (Cr), 39.0-87.1 (Ni), 50.9-144.5 (Cu), and 175.0-251.2 (Zn), which were clearly higher with respect to their corresponding benchmark values. The predominant speciation of Pb was reducible and comprised a residual fraction, whereas a major portion (57.6-95.4%) of Cr, Ni, Cu, and Zn was strongly associated with the residual fractions. Taking as a whole, surface sediments of Zhelin Bay had a 21% probability of toxicity based on the mean effects range-median quotient.

Assessments on surface water resources and their vulnerability and adaptability in China

A clear understanding of the changes of water resources under the background of environmental changes is of great significance for scientific management and utilization of water resources in China. This study systematically analyzed the spatial–temporal variations of surface water resources in China since 2000. Water vulnerability in current (2010s) and its trends from 2000 to late-2010s in different regions of China were also summarized. In addition, the correspondingly adaptive measures to counter regional risks to water resources were proposed. We concluded that the runoff of major rivers had been decreasing in eastern China and increasing in western China during 2000–2018. In the arid area of Northwest China, the alpine runoff has shown an overall upward trend since the late-1990s/early-2000s, with a 10%–25% increase caused by the increase of glacial meltwater and precipitation. While the runoff of each hydrological station in the 2000s–2010s was 34.7% lower than that in the 1950s–2010s on average. The increases in precipitation and glacial meltwater with global warming caused a rapid expansion of lakes in the Qinghai-Tibet Plateau and Xinjiang, thus leading to an increase in total area and water quantity of lakes in China from 1995 to 2015. The mean contribution rates of climate change and human activity to runoff change in river basins of China were 53.5% and 46.5%, respectively, during the period of 2000–2010s. The driving factor of runoff change in many river basins has gradually changed from climate change (1950s‒2000) to human activity (2000–2018). During 2000–2018, the contributions of human activities to runoff change were 50%–80% in major rivers of eastern China. The vulnerability in most areas of Northwest China and North China is generally high, with the vulnerability index greater than 0.6. Comparatively, in Northeast, East, South, and Central China, it is lower or not vulnerable. In Southwest China, the vulnerability varies greatly with Yunnan and Sichuan relatively low while Chongqing and Guizhou relatively high. The precipitation increase, the application of water-saving technology, the establishment of flood control and drought relief engineering facilities, and the introduction of relevant policies and measures have helped to gradually reduce the vulnerability of water resources in most areas of North and Northwest China (except Xinjiang) from 2000 to 2010s. Water vulnerability has been increasing in southern China, caused by climate change and the development of industry and agriculture, which increases water resource exposure since 2000. Based on the typical risk factors and vulnerability characteristics of water resources in different regions, this study proposed some targeted adaptive measures correspondingly so as to scientifically deal with the problems of surface water resources in China.

Effective Falls Detection Method Using Two Tri-Axial Accelerometers

Falls detection systems have been developed in recent years because falls are detrimental events that can have a devastating effect on health of the elderly population. Current fall detecting methods mainly employ accelerometer to discriminate falls from activities of daily living (ADL). However, this makes it difficult to distinguish real falls from certain fall-like activities such as jogging and jumping. In this paper, an accurate fall detection system was implemented using two tri-axial accelerometers. By attaching the accelerometers on the chest and the abdomen, our system can effectively differentiate between falls and non-fall events.The Diff_Z and Sum_diff_Z parameter resulted in falls detection rate of 100%, respectively.
Children in comics: an intercultural history from 1865 to today

Owing to their visual essence and status as a popular, modern medium, comics – newspaper strips, comics magazines and graphic novels – provide valuable insight into the transformation of collective consciousness. This project advances the hypothesis that children in comics are distinctive embodiments of the complex experience of modernity, channeling and tempering modern anxieties and incarnating the freedom denied to adults. In testing this hypothesis, the project constructs the first intercultural history of children in European comics, tracing the changing conceptualizations of child protagonists in popular comics for both children and adults from the mid-19th century to the present. In doing so, it takes key points in European history as well as the history of comics into account. 
Assembling a team of six multilingual researchers, the project uses an interdisciplinary methodology combining comics studies and childhood studies while also incorporating specific insights from cultural studies (history of family life, history of public life, history of the body, affect theory and scholarship on the carnivalesque). This enables the project to analyze the transposition of modern anxieties, conceptualizations of childishness, child-adult power relations, notions of liberty, visualizations of the body, family life, school and public life as well as the presence of affects such as nostalgia and happiness in comics starring children.
The project thus opens up a new field of research lying at the intersection of comics studies and childhood studies and illustrates its potential. In studying popular but often overlooked comics, the project provides crucial historical and analytical material that will shape future comics criticism and the fields associated with childhood studies. Furthermore, the project’s outreach activities will increase collective knowledge about comic strips, which form an important, increasingly visible part of cultural heritage.

The shock-wave application for increasing of a critical current in composite HTSC

This paper aims to find methods for effective pinning centres generation using shock waves in order to increase the current-carrying capability of high temperature superconductors in high magnetic fields. It presents the results of the effect of a shock wave on properties of composite high temperature superconductor tapes (HTSC): YBCO(123) and Bi(2223). To generate the shock wave, authors used the interaction of a solid state target with a high speed cumulative plasma jet generated in a Plasma Focus setup. Shock waves have a front-edge pressure of 1011 Pa. The sample was exposed to the plasma pulse for about 50 ns. A significant and lasting increase of the critical current density of composite HTSC tapes was observed as a result of the effect of shock waves, also in high magnetic fields. This paper discusses the presumed reasons for the increase of the critical current. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Uncertain Data Dependency Constraints in Matrix Models

Uncertain data due to imprecise measurements is commonly specified as bounded intervals in a constraint decision or optimization problem. Dependencies do exist among such data, e.g. upper bound on the sum of uncertain production rates per machine, sum of traffic distribution ratios from a router over several links. For tractability reasons existing approaches in constraint programming or robust optimization frameworks assume independence of the data. This assumption is safe, but can lead to large solution spaces, and a loss of problem structure. Thus it cannot be overlooked. In this paper we identify the context of matrix models and show how data dependency constraints over the columns of such matrices can be modeled and handled efficiently in relationship with the decision variables. Matrix models are linear models whereby the matrix cells specify for instance, the duration of production per item, the production rates, or the wage costs, in applications such as production planning, economics, inventory management. Data imprecision applies to the cells of the matrix and the output vector. Our approach contributes the following results: 1) the identification of the context of matrix models with data constraints, 2) an efficient modeling approach of such constraints that suits solvers from multiple paradigms. An illustration of the approach and its benefits are shown on a production planning problem.
High temporal and spatial-resolution detection of D-layer fluctuations by using time-domain lightning waveforms

[1] This paper presents a new method for probing ionospheric D-layer fluctuations with time-domain very-low and low-frequency (VLF/LF) lightning waveforms detected several hundred kilometers away from lightning storms. The technique compares the amplitude and the time delay between the direct ground wave and the first-hop ionospheric reflection of the lightning signal to measure the apparent D-layer reflectivity and height. This time-domain technique allows a higher time and spatial resolution measurement of the D-layer fluctuations compared to previously reported frequency-domain techniques. For a region near a nighttime thunderstorm, results demonstrate that the apparent reflectivity and height exhibit significant variation on spatial scales of tens of kilometers and over time periods of hours. The range of the reflectivity variation was observed as large as 100% away from the averaged reflectivity for some localized regions, and the height varies by as much as 5% (4 km). The time scales and propagation velocities of the fluctuations appear to be consistent with signatures of atmospheric gravity waves at D-layer altitudes, and the direction of the fluctuation propagation suggests that the gravity waves are originated from the storm. Superimposed on the fluctuations, a general decreasing trend (by ∼4–8 km) in reflection height over the nighttime is observed. In some localized ionosphere regions, apparent splitting of the D-layer by 2–4 km is observed to last a short time period of about 10 min.
Swarming : An Investigation Practice Supporting a Bottom-up Ecological Transition

Dans cet article, nous rendons compte des pratiques d'essaimage d'initiatives locales de transition portées par des collectifs citoyens et associatifs en région Bourgogne Franche-Comté. L'essaimage, défini comme une façon d'enquêter pour agir, caractérise un « activisme environnemental du faire » qui se structure de manière réticulaire et translocale. Ces multiples initiatives qui font des gestes du quotidien un levier de transformation écologique s'activent avec ou sans les institutions territoriales. Celles-ci, indépendamment de l'écho qu'elles renvoient à ces expérimentations, sont interpellées dans leur manière de concevoir l'action publique sous contrainte écologique forte.

ELECTRICAL ENERGY CONVERSION CIRCUIT DEVICE

The present invention is related to an electrical energy conversion circuit device (190), a method (600) of operating an electrical energy conversion circuit device, an electrical apparatus (500) and a computer program. The circuit device (190) allows earth connection and comprises two parallel connected buck-boost converters for converting a direct input voltage (110) into a direct output voltage (120). The converters are adapted to generate two phase-shifted currents (131, 141) that are received by an output capacitor (160). Due to the phase-shift, a current ripple is reduced. The direct output voltage (120) and the direct input voltage (110) preferentially have a common potential (114) and are of opposite polarities. Therefore, a second voltage of high magnitude, the sum of the direct input voltage (110) and the direct output voltage (120) is also provided.
