Analyse des anomalies de Potentiels Spontanés et mise en évidence d'un axe préférentiel d'écoulement d'eaux souterraines en zone volcanique : cas du versant nord-est du Mont Cameroun

Dans les formations volcaniques a porosite elevee telles que les basaltes pyroclastiques, l'amplitude des anomalies des potentiels spontanes (PS) est liee de facon lineaire a l'epaisseur de la zone non saturee. Ceci est rendu possible lorsque deux conditions principales sont reunies : d'une part, la presence d'un fort contraste de resistivite electrique entre la zone non saturee et l'ensemble constitue par la zone saturee et le substratum impermeable, d'autre part, l'homogeneite electrique de la zone non saturee. De cette correlation lineaire, il est developpe un concept de surface geophysique nommee Surface de Potentiels Spontanes (SPS), calculee a partir des donnees des PS et de la topographie. L'interpretation en termes d'ecoulements d'eau souterraines consiste a definir sur cette SPS, des axes de circulation preferentielle et des lignes de partage des eaux. Dans le contexte hydrogeologique des stratovolcans tel que le Mont Cameroun, ces deux conditions ne sont pas toujours reunies de facon ideale ; il convient donc de formuler des hypotheses d'interpretation de la SPS et d'identification d'eventuels ecoulements d'eau au sein de ces formations volcaniques. Dans le cadre de la presente etude, l'hypothese retenue pour interpreter la SPS calculee est que cette derniere correspond a une surface d'anciennes coulees a structure massive, ravinees et servant de substratum impermeable aux eaux souterraines. Les points bas de ce paleorelief determines a partir de la SPS, ont permis de proposer un axe preferentiel d'ecoulement des eaux souterraines dans la zone etudiee.

Cultural change for a bearable climate

Social, economic and cultural systems will have to evolve so that they can again exist within the boundaries of nature Stabilising the climate and curbing ecological decline more broadly will take nothing less than transforming cultural systems so that living sustainably becomes as natural as living as a consumer feels today. To do that, it will be necessary to harness leading societal institutions just as consumer interests did in the past century, when they so effectively normalised consumerism.
The Effect of Hydrothermal Duration on the Formation of Activated Edgesites of 2-H Molybdenum Disulfide andthe of Hydrogen Evolution Performances of the Material

Molybdenum disulfide (MoS2) is a nontoxic, environmentally friendly, abundant semiconducting material which is widely used in the areas of hydrogen storage, gas sensing and, solid super lubricant. It has three major phases called 1-T MoS2, 2-H MoS2 and 3-R MoS2. Among them 2-H MoS2 form is the stable form which has a hexagonal phase structure with an activated edge. Therefore, Activation of the material is possibly changing by making differences on nature of material edges. In this work, we report that influence of duration of hydrothermal process toward the growth of edge sites of 2-H molybdenum disulfide nanocomposites. In this study, we have synthesized three 2-H MoS2 nanostructures by facile hydrothermal route by using Ammonium molybdate, Thioacetamide, and urea as the basic precursors. All the samples were prepared at 200 ℃ temperature by changing the duration of hydrothermal process as 24h, 36h and, 48h. The samples were characterized by powder X-ray diffraction (PXRD) and Scanning electron microscope (SEM) for the phase confirmation and morphological characterizations respectively. Next, Electrochemical characterizations were carried out by using linear sweep voltammetry under the basic medium. Powder X-ray diffraction results confirmed that the prepared three products were at the Hexagonal phase of MoS2 with minor level of impurity. The SEM images show that the as-prepared structures have a Plate-like structure with sharped edges. Then the Linear sweep voltammetry of the materials verified that the high number of sharped edges of MoS2 nanocomposites leads to excellent activity for Hydrogen evaluation reaction (HER). When compared to others, 48 h material has a higher number of sharped edge sites and the best performances in HER. Finally, the sharpness and amounts of edge sites are possible to control with the duration of hydrothermal process and 2-H MoS2 with more number of sharped edge sites were found to increase the performances of HER.
Modeling medium dense cellular network and evaluation of probability of coverage

It is well known that cellular networks are continuously densifying at an enormous rate everywhere around the globe. Much work has been done in modeling ultra‐dense cellular (UDC) network. However, at present, there are no satisfactory models for medium dense cellular (MDC) network. Motivation of our work is to fill this gap in the literature. In particular, we propose to develop a model for the MDC network and derive the coverage probability. In this article, an optimization problem based on sparse dictionary learning (SDL) has been used to find a linear dependency between the UDC region and MDC region with respect to the base stations. A model for the MDC network is defined based on the linear dependency produced using SDL. The linear dependency allows us to define a relation connecting the distance metric between the MDC and UDC regions. Different terms in the expression for the equivalent distance metric have been identified, and the most relevant terms have been used to evaluate the coverage probability of the MDC network. Validation of our model has been done by comparing the correlation graph between the proposed model and the ideal model. Our proposed network model opens up the scope for more accurate modeling and analysis of medium‐dense cellular networks.

Autonomous Multiframe Point Cloud Fusion Method for mmWave Radar

This article proposed an autonomous multiframe fusion method of millimeter-wave (mmWave) radar point cloud suitable for low-crowd density indoor scenes to overcome the problem of sparse target points in the application of frequency-modulated continuous wave (FMCW) radar in indoor 4-D point cloud imaging. Without other sensors, in the static or translational state of the radar, the static and dynamic target points in the radar field of vision are distinguished through multiple velocity iterations, and then, the static target points are used to estimate the velocity of the radar itself. By calculating the displacement of the radar within a frame time, we carry out velocity filtering on the point cloud to remove the target points with large differences. Finally, the radar point cloud data of each frame is converted to the same geographic coordinate system to achieve 4-D point cloud multiframe fusion. The experimental results show that the presented method can accurately estimate the velocity of the radar and correct the coordinates of each frame point cloud. According to the imaging results, the proposed algorithm can greatly increase the imaging density of point cloud without defocusing, which improves the accuracy and readability of point cloud image with the imaging ability of static and dynamic targets.
The Assessment of Withdrawal Interval for Enrofloxacin in Yellow Catfish (Pelteobagrus fulvidraco) after Multiple Oral Administrations at Disparate Temperatures

Simple Summary Enrofloxacin (EF) is an important antibiotic in global aquaculture. Due to the abuse and the emergence of drug resistance, the excess use of EF has occurred in recent years to result in residue exceeding in the edible tissues of aquatic animals. Withdrawal time (WT) is a red line to ensure food safety for humans. However, there is no related report of WT for EF in yellow catfish (Pelteobagrus fulvidraco). In addition to yellow catfish being sensitive to temperature, it can alter the disposition and elimination of EF and its main metabolite in fish bodies, ciprofloxacin (CF), thereby changing the WT in tissues. Therefore, we will conduct a WT estimation of EF in yellow catfish at different temperatures to establish related regulations to help residue surveillance in fish products. Abstract The objective of the present study was to investigate the residue depletion of EF and CF in yellow catfish to estimate its WTs in plasma and tissues after multiple oral doses for 3 days at 20 mg/kg at 15, 20, and 25 °C. Samples were collected at pre-designed time points after oral doses. A validated method was performed to quantify EF and CF in plasma and tissues by high-performance liquid chromatography. Statistical differences were conducted using one-way ANOVA analysis. According to the maximum residue limit of China and Europe considering 95% percentile with 95% confidence, the WTs were estimated to be 44, 72, 66, 99, and 95 days at 15 °C; 32, 66, 65, 86, and 73 days at 20 °C; and 32, 61, 64, 55, and 59 days at 25 °C in the plasma, muscle and skin, gill, liver, and kidney, respectively. We found that increased temperature shortened the WTs in plasma and tissues. Therefore, this study can help the risk assessment of EF in aquatic products for human health at different temperatures to avoid residue violation.
Anti-aliasing and Continuity with Trapezoidal Shadow Maps

This paper proposes a new shadow map technique termed trapezoidal shadow maps to calculate high quality shadows in real-time applications. To address the resolution problem of the standard shadow map approach, our technique approximates the eye's frustum as seen from the light with a trapezoid to warp it onto a shadow map. Such a trapezoidal approximation, which may first seem straightforward, is carefully designed to achieve the goal of good shadow quality for objects from near to far, and to address the continuity problem that is found in all existing shadow map approaches. The continuity problem occurs mainly when the shadow map quality changes significantly from frame to frame due to the motion of the eye or the light. This results in flickering of shadows. On the whole, our proposed approach is simple to implement without using complex data structures and it maps well to graphics hardware as shown in our experiments with large virtual scenes of hundreds of thousands to over a million of triangles.
Plasma Electrolytic Modification of Zirconium and Its Alloys: Brief Review

The review focuses on the surface modification of Zr and its alloys, which is necessary to expand the applications of these kinds of materials. Data on the properties of pure zirconium and its alloys are presented. Since surface engineering and the operation of the above materials are in most cases associated with the formation of oxide coatings, information on the characteristics of ZrO2 is given. In addition, attention is paid to phasing in the zirconium–oxygen system. It is noted that the most effective method of surface engineering of Zr and its alloys is plasma electrolytic modification (PEM) technology. Specific examples and modes of modification are described, and the reached results are analyzed. The relevance, novelty and originality of the review are determined by the insufficient knowledge about a number of practical features concerning the formation of functional oxide coatings on Zr and some of its alloys by the technology of PEM. In particular, the information on the phase composition and possibilities of stabilization of the tetragonal and cubic modifications of ZrO2, the effects of the component composition of electrolyte solutions and electrolyte suspensions, and the specifics of the treatment of additive shaping and deformed materials are rather contradictory. This review aims to collect recent advances and provide insights into the trends in the modification of Zr and its alloys, promote the formulation of practical recommendations and assess the development prospects.
Petroleum Exploration Risk Reduction Using New Geoscience Technology

As economics of the oil and gas industry become more restrictive, the need for new means of improving exploration risks and reducing expenses is becoming more acute. Partnerships between industry and academia are making significant improvements in four general areas: Seismic acquisition, reservoir characterization, quantitative structural modeling, and geochemical inversion. In marine seismic acquisition the vertical cable concept utilizes hydrophones suspended at fixed locations vertically within the water column by buoys. There are numerous advantages of vertical cable technology over conventional 3-D seismic acquisition. In a related methodology, ‘Borehole Seismic,’ seismic energy is passed between wells and valuable information on reservoir geometry, porosity, lithology, and oil saturation is extracted from the P-wave and S-wave data. In association with seismic methods of determining the external geometry and the internal properties of a reservoir, 3-dimensional sedimentation-simulation models, based on physical, hydrologic, erosional and transport processes, are being utilized for stratigraphic analysis. In addition, powerful, 1-D, coupled reaction-transport models are being used to simulate diagenesis processes in reservoir rocks. At the regional scale, the bridging of quantitative structural concepts with seismic interpretation has lead to breakthroughs in structural analysis, particularly in complex terrains. Such analyses are becoming more accurate and cost effective when tied to highly advanced, remote-sensing, multi-spectral data acquisition and image processing technology. Emerging technology in petroleum geochemistry enables geoscientists to infer the character, age, maturity, identity and location of source rocks from crude oil characteristics (‘Geochemical Inversion’) and to better estimate hydrocarbon-supply volumetrics, which can be invaluable in understanding petroleum systems and in reducing exploration risks and associated expenses.
Rodent Whole-Brain fMRI Data Preprocessing Toolbox.

Rodent Whole-Brain fMRI Data Preprocessing Toolbox is a generally applicable and user-friendly functional magnetic resonance imaging (fMRI) preprocessing toolbox for whole-brain group datasets in rodents. Preprocessing of rodent fMRI data is challenging when using toolboxes designed for human data, so this toolbox contains procedures and parameters that are specific for mice and rats. It provides the standard preprocessing procedures for preprocessing rodent brains as described in Chuang et al. (1) and Lee et al. (2). It normalizes the group datasets to a standard template and then extracts time series based on an atlas. Different from the existing preprocessing pipelines, which are applicable only for a single animal model [e.g., either rats (3, 4) or mice (5)], this is the first software toolbox that is generalized for both mouse and rat group data. This is also the first software toolbox that allows a variety of combinations of preprocessing procedures and parameters that are specified by users depending on the applications. Moreover, a user-specified repressors file can be added for task pattern regressions in addition to the classical detrending, motion parameters, brain tissue or noise regressions, etc. (see Figure 1). This software toolbox and a comprehensive user manual are available at https://github.com/GT-Emory MINDlab/rodent-whole-brain-preprocessing-recipe. A Linux or Mac system with FSL5.0 (6), AFNI (7, 8), advanced neuroimaging tools (ANTs; 9, 10), and MATLAB (R.2018a or a later version) installed is required. For Windows systems, it is also possible to install these packages through a Windows Subsystem for Linux (WSL; see “SoftwareInstallation_fsl_afni_ants.txt” for more details), which is less preferable due to the lack of broad usages and support.

Verification set Haringvliet

The project HYDRA was set-up by the National Institute for Coastal & Marine Management / RIKZ to provide the hydraulic input parameters for the safety analysis along the coast and in the estuaries of the Netherlands. One part of the HYDRA project considers wave measurements (field as well as laboratory) which are necessary for validation of numerical wave modelling. A very interesting measurement campaign was conducted in fall 1982 in a shallow water region off-shore the Haringvliet-sluices in the Netherlands. The field data were presented and used in several publications, which have lead to some confusion and misunderstanding of interpretation of the data and availability. That is why Rijkswaterstaat decided in 1994 to process and present the original wave data again and focus on the storm that took place at October 14 and 15 in 1982. This report gives a presentation of the Haringvliet wave data 1982, and the way the standard classification of the wave data sets is available at RIKZ. Chapter 2 gives a description of the Haringvliet area. Bathymetry, monitoring stations and available field data will be summerized. Definitions of hydraulic parameters and classification of the files that contain the relevant data are given in chapter 3. Chapter 4 reviews the obtained data set. Observed time histories of hydraulic parameters as well as energy density spectra are presented in appendices.
Integrative review: postcraniotomy pain in the brain tumour patient.

AIM To conduct an integrative review to examine evidence of pain and associated symptoms in adult (≥21 years of age), postcraniotomy, brain tumour patients hospitalized on intensive care units. BACKGROUND Healthcare providers believe craniotomies are less painful than other surgical procedures. Understanding how postcraniotomy pain unfolds over time will help inform patient care and aid in future research and policy development. DESIGN Systematic literature search to identify relevant literature. Information abstracted using the Theory of Unpleasant Symptoms' concepts of influencing factors, symptom clusters and patient performance. Inclusion criteria were indexed, peer-reviewed, full-length, English-language articles. Keywords were 'traumatic brain injury', 'pain, post-operative', 'brain injuries', 'postoperative pain', 'craniotomy', 'decompressive craniectomy' and 'trephining'. DATA SOURCES Medline, OVID, PubMed and CINAHL databases from 2000-2014. REVIEW METHOD Cooper's five-stage integrative review method was used to assess and synthesize literature. RESULTS The search yielded 115 manuscripts, with 26 meeting inclusion criteria. Most studies were randomized, controlled trials conducted outside of the United States. All tested pharmacological pain interventions. Postcraniotomy brain tumour pain was well-documented and associated with nausea, vomiting and changes in blood pressure, and it impacted the patient's length of hospital stay, but there was no consensus for how best to treat such pain. CONCLUSION The Theory of Unpleasant Symptoms provided structure to the search. Postcraniotomy pain is experienced by patients, but associated symptoms and impact on patient performance remain poorly understood. Further research is needed to improve understanding and management of postcraniotomy pain in this population.

Characterising cytotoxicity and genotoxicity of chemotherapeutic agents (Etoposide and Vincristine) on TK6, a human lymphoblastoid cell line

The ability of the chemotherapeutic agents namely etoposide and vincristine to cause cytotoxic and genotoxic damage to the human lymphoblastoid cell line, TK6, was at the centre of this study. Four different cytotoxic assays were tested for their ability to assess the cytotoxicity of the agents as well as two genotoxic assays to examine their ability to induce DNA damage. The TK6 cell line was exposed to increasing doses of the chemotherapeutic agents and cytoxicity assessed by in vitro trypan blue, neutral red uptake, LDH leakage and the glucose oxidase assays. The trypan blue assay was deemed to be the most beneficial due to its ease and speed of quantifying the number of non-viable cells as through the loss of their membrane integrity they stain the characteristic blue colour. Genotoxicity on the other hand was measured by two assays; the micronucleus and Comet assays. Both are currently used within the laboratory setting but this study concluded the Comet assay was the best method for measuring DNA damage. Additionally, vincristine was found to be more cytotoxic than etoposide and also exerted further genotoxic effects upon the cells. Although only a pilot study, this work aimed to define the best cytotoxic and genotoxic detection methods using two widely used chemotherapeutic agents and show how they can impact upon cells and cancer/leukemic treatment regimens.
