The Behavior of Online Consumer Opinions Case Tunisian Communities

Online consumer opinions are an essential source of information on goods and services, with the framework of a Research Online Purchase Offline behavior. However, in a virtual environment, there are two types of consumers: opinion leaders and "lurkers" who do not participate in virtual communities. This research presents the results of a qualitative study on the obstacles and motivations for the participation of "lurkers" in Social Media and especially case of Facebook groups. It shows that even though "Lurkers" consider virtual communities as a public space that can triturate their confidentiality, in some cases they can manifest themselves and give rise to new behavior, which is "mobilizing behavior". Background/Objectives: The main purpose of the research is to study and understand, through a preliminary qualitative study, the barriers, and motivations of passive users in a virtual community on Facebook. The theoretical scope of this research is based on a lack of theoretical work, addressing the barriers and motivations to convert a Lurker into an Opinion Leader (Vasic, N & al. 2019) in the context of Research Online Purchase Offline "ROPO" behavior. Methods/Statistical. Methodological tools of the research methods were qualitative, a survey based on an interview is conducted with a sample of the relevant population, namely, subsidiaries of Tunisian communities’ groups. Given the exploratory nature of this study, the choice of a qualitative analysis seems appropriate. The method of data collection through semi-structured interviews Findings: This study examined the literature on online behaviors and aimed to provide a comprehensive understanding of Lurkers' behavior context through a qualitative exploratory study. The qualitative study shows that the "Lurkers" brakes are mainly around the fact that they want to protect their private lives by leaving as little data as possible so as not to receive abusive requests for additions, they try to keep some perspective to avoid any kind of conflict with strangers when it comes to different opinions. Improvements: This study can provide input at the managerial level, especially for creators of virtual communities. In practice, brands develop virtual communities intending to improve the "consumer-brand" relationship as well as the relationship between consumers. The obstacles for Lurkers to participate can give brands a clear idea of the need to develop engagement platforms. More specifically, the brand must give more opportunities to the lurkers to give their opinions so that they can participate without fear.

The evolution of transport networks and the regional water environment: the case of Chinese high-speed rail

ABSTRACT We investigate empirically the role of an evolving high-speed rail (HSR) network in improving the regional water environment via industry agglomeration. We use Graph Theory to construct a data set reflecting a continuous evolution of cities’ accessibility to the HSR network. We find that cities with higher degree and closeness centralities in the HSR network tend to have less industrial water pollution. The reallocation of a high-skilled labour force leads to the agglomeration of skill-intensive and clean industries in cities with higher HSR centralities. We show that the evolution of the HSR networks is indeed conducive to the sustainable regional development.
A Bioinspired Humanoid Foot Mechanism

This paper introduces an innovative robotic foot design inspired by the functionality and the anatomy of the human foot. Most humanoid robots are characterized by flat, rigid feet with limited mobility, which cannot emulate the physical behavior of the foot–ground interaction. The proposed foot mechanism consists of three main bodies, to represent the heel, plant, and toes, connected by compliant joints for improved balancing and impact absorption. The functional requirements were extracted from medical literature, and were acquired through a motion capture system, and the proposed design was validated with a numerical simulation.
Power Loop Busbars Design and Experimental Validation of 1 kV, 5 kA Solid-State Circuit Breaker Using Parallel Connected RB-IGCTs

This article investigates the design of a 1 kV, 5 kA solid-state circuit breaker by using parallel connection of reverse blocking IGCTs (RB-IGCT). The presented breaker topology is based on the parallel connection of low conduction loss RB-IGCTs which delivers efficiency as high as 99.9%. The focus of this article is on the power loop design and experimental validation of parallel connection of two and three RB-IGCTs with emphasis on current sharing during dynamic events such as short-circuits. A 3-D CAD-based design of power loop busbars was verified by several simulation test cases to represent dynamic current sharing under variations in RB-IGCT package impedances. An optimized busbar design approach and its tradeoffs are also discussed with simulation verification. The experimental results confirm that the parallel topology is able to perform current interruption during overload and short-circuit situations up to 10 kA for two devices in parallel and up to 14 kA for three devices in parallel - with current deviation from the mean as little as 6%.
Transcriptome Analysis for Fraxinus mandshurica Rupr. Seedlings from Different Carbon Sequestration Provenances in Response to Nitrogen Deficiency

To explore the molecular regulatory mechanism of high-carbon (C) sequestration Fraxinus mandshurica Rupr. (F. mandshurica) provenance and the expression profile of F. mandshurica during nitrogen (N) starvation, the foliage and roots of the annual Wuchang (WC) seedlings with greater C amount and Hailin (HL) seedlings with smaller C amount, which were grown in N-deficient nutrition and complete N, were used for RNA-seq and physiological determination, respectively. One thousand and fifty-seven differentially expressed genes (DEGs) between WC and HL and 8173 DEGs related to N deficiency were identified, respectively. The root of F. mandshurica responded to N deficiency more strongly than foliar. The target genes that responded to N deficiency in roots were mainly regulatory genes (transcription factors, hormones and protein kinases), and their response patterns were upregulated. The growth and N concentration in both WC and HL were reduced by the N deficiency, which might result from the decrease of the leaf Nitrate reductase (NR) and glutamine synthetase (GS) enzyme activity and ABA content, although the root-to-shoot ratio; lateral root number; lignin content; endogenous hormones content (GA, IAA and ZR); root GS and glutamate synthetase activity and transcriptional level of most of the regulatory genes were increased. The C sequestration capacity in WC was greater than that in HL, which related to the higher GS enzymes activity and transcriptional levels of regulatory genes and metabolic genes (terpenes, carbohydrates, and lipid energy). However, the C sequestration advantage of WC was significantly reduced by the N deficiency, which was due to the smaller response to N deficiency compared to HL.
Sustainability Assessment and Agricultural Supply Chains Evidence-Based Multidimensional Analyses as Tools for Strategic Decision-Making—The Case of the Pineapple Supply Chain in Benin

Contributing to Sustainable Development Goals and Agenda 2030 is a shared objective of all institutions and people. The challenges differ according to the characteristics of every context. In developing countries, strongly dependent on the agricultural sector, agricultural supply chains are recognized as crucial for economic growth and enablers for livelihood improvement. Moreover, sustainable development issues are correlated and can meet in agricultural supply chains. For several decades, parallel to decision-makers, the research community has elaborated sustainability assessment tools. Such tools evolved to fit with actuality, but it is challenging to find decision-making support tools for sustainable development adequate in agricultural supply chains and developing countries contexts. There is a necessity to define evidence-based tools and exhaustive analytical frameworks according to sustainability multidimensionality and strategical tradeoffs necessity. The VCA4D method aims to go beyond the limits of previous methods. It proposes a combination of multidisciplinary analytical tools applied empirically to analyze agricultural supply chains in their context. It provides evidence-based analytical results allowing to identify enablers for strategic sustainable and inclusive interventions. However, to even better meet contextual exhaustiveness’s expectations and indicators’ robustness to lead to relevant interventions, we should insist on a stricter framing of contextual data collection processes.
Wireless Motion Capture System for Upper Limb Rehabilitation

This work is devoted to the presentation of a Wireless Sensor System implementation for upper limb rehabilitation to function as a complementary system for a patient’s progress supervision during rehabilitation exercises. A cost effective motion capture sensor node composed by a 9 Degrees-of-Freedom (DoF) Inertial Measurement Unit (IMU) is mounted on the patient’s upper limb segments and sends wirelessly the corresponding measured signals to a base station. The sensor orientation and the upper limb individual segments movement in 3-Dimensional (3D) space are derived by processing the sensors’ raw data. For the latter purpose, a biomechanical model which resembles that of a kinematic model of a robotic arm based on the Denavit-Hartenberg (DH) configuration is used to approximate in real time the upper limb movements. The joint angles of the upper limb model are estimated from the extracted sensor node’s orientation angles. The experimental results of a human performing common rehabilitation exercises using the proposed motion capture sensor node are compared with the ones using an off-the-shelf sensor. This comparison results to very low error rates with the root mean square error (RMSE) being about 0.02 m.
Nanocellulose: a bioadsorbent for chemical contaminant remediation

Chemical contaminants such as heavy metals, dyes, and organic oils seriously affect the environment and threaten human health. About 2 million tons of waste is released every day into the water system. Heavy metals are the largest contributor which cover about 31% of the total composition of water contaminants. Every day, approximately 14 000 people die due to environmental exposure to selected chemicals. Removal of these contaminants down to safe levels is expensive, high energy and unsustainable by current approaches such as oxidation, biodegradation, photocatalysis, precipitation, reverse osmosis and adsorption. A combination of biosorption and nanotechnology offers a new way to remediate these chemical contaminants. Nanostructured materials are proven to have higher adsorption capacities than the same material in its larger-scale form. Nanocellulose is very promising as a high-performance bioadsorbent due to its interesting characteristics of high adsorption capacity, high mechanical strength, hydrophilic surface chemistry, renewability and biodegradability. It has been proven to have higher adsorption capacity and better binding affinity than other similar materials at the macroscale. The high specific surface area and abundance of hydroxyl groups within lead to the possible functionalization of this material for decontamination purposes. Several research papers have shown the effectiveness of nanocellulose in the remediation of chemical contaminants. This review aims to provide an overview of the most recent developments regarding nanocellulose as an adsorbent for chemical contamination remediation. Recent advancements regarding the modification of nanocellulose to enhance its adsorption efficiency towards heavy metals, dyes and organic oils were highlighted. Moreover, the desorption capability and environmental issue related to every developed nanocellulose-based adsorbent were also tackled.

Models and Mechanisms of Oxygen Evolution Reaction on Electrocatalytic Surface

A profound change has taken place in understanding surface electrochemistry during water-splitting reaction due to the accumulated knowledge over the past decades and supported by recent advances in spectroscopic techniques and high-performance quantum chemical simulations. The design of electrocatalysts has been improved due to better understanding of surface structures of electrocatalysts and their active sites. This review provides insights into both theoretical and experimental electrochemistry that are directed towards a better understanding of the rate-determining step of water splitting, i.e., oxygen evolution reaction (OER). The emphasis of this review is on the origin of the electrocatalytic activity of nanostructured catalysts toward the aforementioned reaction by correlating the electrode performance with their intrinsic electrochemical properties. Also, the design aspects of acidic- and alkaline-medium electrocatalysts is discussed from preliminary discussion on active site engineering to a more applied concern of achieving highly stable and active electrode fabrication. The design concerns while choosing a support for OER electrocatalyst has also been discussed. At the end, challenges in electrolyser designs and problems faced by the industry to commercialize the electrolyser in a cost-effective manner have been discussed.
Wastewater Clarification and Microbial Load Reduction Using Agro-Forestry and Agricultural Wastes

Five agro-wastes, namely: cassava peels, Irish potato peels, Jatropha curcas seeds, Moringa oleifera seeds and rice husks were investigated as plant-based coagulants for turbidity and microbial load removal from sewage wastewater. Moringa oleifera and Jatropha curcas seeds before usage were defatted with 95% ethanol and the active coagulating component was extracted with 1.0 M NaCl. For the other three agro-wastes, their ashes were evaluated for turbidity and microbial load removal. The ash was prepared through pyrolysis of the raw biomass at a temperature of 800 °C for 3 h. The effect of pH, coagulant dose, settling time on turbidity reduction was investigated using sewage wastewater with an initial turbidity of 464.11 ± 0.13 NTU. The microbial load removal of the coagulants was investigated using three media onto which 1 mL of treated wastewater was poured and streaks were made using sterile swabs and then incubated at 37 °C for 24 h. Jatropha curcas and rice husks ashes exhibited the maximum turbidity reduction of 97.0% and 95.0%, respectively at pH 2, whereas for Moringa oleifera, the highest turbidity removal (96.0%) was achieved between pH 6 and 10. Additionally, it was observed that the electrical conductivity and total dissolved solids of the clarified wastewater increased as the doses were increased for all coagulants due to inorganic salts contained in seeds. The microbial load understudy was successfully reduced in wastewater clarified with Jatropha curcas and rice husks ashes, contrary to Moringa oleifera that increased microbial load content. The raw biomass and ashes for cassava and Irish potato peels could not clarify sewage wastewater. The results from this study have demonstrated that plant-based materials used performed effectively in turbidity and bacteria removal from sewage wastewater.

High-Level Doping of Nitrogen, Phosphorus, and Sulfur into Activated Carbon Monoliths and Their Electrochemical Capacitances

The present report demonstrates a new technique for doping heteroatoms (nitrogen, phosphorus, and sulfur) into carbon materials via a versatile post-treatment. The heat-treatment of carbon materials with a reagent, which is stable at ambient temperatures and evolves reactive gases on heating, in a vacuum-closed tube allows the introduction of various heteroatom-containing functional groups into a carbon matrix. In addition, the sequential doping reactions give rise to dual- and triple-heteroatom-doped carbons. The pore properties of the precursor carbon materials are preserved through each heteroatom doping process, which indicates that independent tuning of heteroatom doping and nanostructural morphology can be achieved in various carbon materials. The electrochemical investigation on the undoped and doped carbon monolithic electrodes applied to supercapacitors provides insights into the effects of heteroatom doping on electrochemical capacitance.
Acoustic phonon softening and reduced thermal conductivity in Mg2Si1−xSnx solid solutions

The measured thermal conductivity κph of Mg2Si1−xSnx solid solutions exhibits a dramatic decrease compared with Mg2Si and Mg2Sn. By solving the full Boltzmann equation, the significantly reduced κph was quantitatively reproduced by our calculations. Besides the expected increase in phonon-phonon scattering, we also observed acoustic phonon softening in Mg2Si1−xSnx, despite their smaller average atomic mass relative to Mg2Sn. In agreement with measurements, the lowest κph appears in Mg2Si0.375Sn0. 625, which has the shortest mean free path and lowest group velocity. According to our calculated cumulative curve, nanoinclusions of tens of nanometers are suggested for the further reduction of κph in Mg2Si1−xSnx solid solution.

Retinal Genomic Fabrics Remodeling after Optic Nerve Injury

Glaucoma is a multifactorial neurodegenerative disease, characterized by degeneration of the retinal ganglion cells (RGCs). There has been little progress in developing efficient strategies for neuroprotection in glaucoma. We profiled the retina transcriptome of Lister Hooded rats at 2 weeks after optic nerve crush (ONC) and analyzed the data from the Genomic Fabric Paradigm (GFP) to bring additional insights into the molecular mechanisms of the retinal remodeling after induction of RGC degeneration. GFP considers for the expression of each gene 3 independent characteristics: level, variability and correlation with each other gene. Thus, the 17,657 quantified genes our study generated a total of 155,911,310 values to analyze. This represents 8,830x more data per condition than a traditional transcriptomic analysis. ONC led to a 57% reduction in RGC numbers as detected by retrograde labeling with DiI. We observed a higher Relative Expression Variability after ONC. Gene expression stability was used as a measure of transcription control and disclosed a robust reduction in the number of very stably expressed genes. Predicted Protein-Protein interaction (PPI) analysis with STRING revealed axon and neuron projection as mostly decreased processes, consistent with RGC degeneration. Conversely, immune response PPIs were found among up-regulated genes. Enrichment analysis showed that Complement Cascade and Notch Signaling Pathway, as well as Oxidative Stress and Kit Receptor Pathway were affected after ONC. To expand our studies of altered molecular pathways, we examined the pair-wise coordination of gene expressions within each pathway and within the entire transcriptome using Pearson correlations. ONC increased the number of synergistically coordinated pairs of genes and the number of similar profiles mainly in Complement Cascade and Notch Signaling Pathway. This deep bioinformatic study provides novel insights beyond the regulation of individual gene expression and discloses changes in the control of expression of Complement Cascade and Notch Signaling functional pathways that may be relevant for both RGC degeneration and remodeling of the retinal tissue after ONC.
