With its 4.7 km/km² of public roads, Southern Belgium (Wallonia) has one of the densest road network of Western Europe. This network as well as the observed increase in main game species populations (red deer, roe deer and wild boar) make Wallonia an interesting region for studying the patterns of traffic accidents caused by animals. Moreover, compared to most of European countries, no statistics are available for this area. To shed light on the current situation of wildlife roadkills, the police database of traffic accident statement was thoroughly investigated. Those statements concern accidents that occurred between 2006 and 2010. Each record includes date, time, species involved and information about the location of the accident event. Based on this dataset, we have analysed (i) composition and percentage of involved species, (ii) the consequence (material damages / bodily injuries), (iii) the spatial (type of roads, proximity to landscape features, ‘hot spot’ map) and (iv) temporal (daily, weekly and seasonal) distribution of animal-related accidents. In conclusion future research perspectives are presented. [less ▲]

Controlled radical polymerization (CRP) techniques offer the opportunity to properly design polymer chains and adjust their chemical and physical properties. Among these techniques, cobalt-mediated radical polymerization (CMRP) distinguished itself by the high level of control imparted to the polymerization of acrylic and vinyl ester monomers, even for high molar masses. This article summarizes for the first time the advances in understanding and synthetic scope of CMRP since its discovery. Notably, the cobalt–carbon bond formation by dual contribution of reversible termination and degenerative chain transfer is discussed, as well as the impact of additives able to coordinate the metal. The potential of computational chemistry in the field of CMRP as a rationalization and predicting tool is also presented. These mechanistic considerations and achievements in macromolecular engineering will be discussed along with challenges and future prospects in order to assess the CMRP system as a whole. [less ▲]

Due to increase of the urbanization and raising the number of the vehicles road traffic incident and delay time in traffic jam are the main concern of countries in all over the world. Due to this problem drivers face an elevated crash risk especially when drivers on freeway ramp interchanges compared with other sections of freeways. The definition of ramp was based on the type and number of lanes used by traffic to freeways. The vehicle accidents are prevalent on highway ramps because of over-speeding, related to the characteristics and circumstances of ramps. Site survey and observation has been done for each location to identify the road condition, adjacent environment and vehicle operations. SPSS is used to analysis the accidents that they are collected data from case study. Descriptive analyses are performed by output of the analyzing data of accident. Differences in accident rates are due to driver behavior, weather potential safety issues were identified at interchanges. Ramps are scheduled for auditing based on descending road speed limits.

Introduction and Background: Carbohydrate-based surfactants (CBS) are, today, among the most attractive amphiphilic compounds owing to their high potentiality for a large product concept. The main fundamental reasons are the abundance of their precursors from renewable resources, the excellent environmental compatibility, and the quasi-unlimited availability of their molecular structure and geometry. Based on the latter aspect, CBS would be expected to generate a wide range of functionalities and activities for food and non-food applications. All kinds of amphiphilic compounds including small surfactants, bolaforms, geminis, oligomeric, and polymeric molecules with a single or a multiple hydrophobic tails can be designed by synthetic routes thanks to a large number of reactive chemical groups in their basic structure. Consequently, various methodologies are required, and could be used in complementary for identifying all of their potentiality for further development. Methodology: The methodology is based on the characterization in the laboratory scale, i.e. using only small amounts of sample, of CBS properties at fluid and solid interfaces, in bulk liquid phases, and at the solid state with simplified models. Results and Discussion: In this communication, an overview of functionality and activity-predicting methods for a wide range of CBS structures varying in head polar groups, hydrophobic tail and number, and linkers will be presented and discussed. Performances and complementarities of different approaches, methodologies, and techniques will be emphasized. These include sample preparation and analysis procedures, interfacial-characterizing instruments, mainly tensiometers and Langmuir balances used both in dynamic and (quasi)-static modes, particle size and electrical charge analyser, and (micro)calorimeters using differential scanning, isothermal titration, and thermogravimetry methods. Conclusion: The knowledge of these basic properties is helpful for predicting their main activities and functionalities like their aptitude for forming and stabilizing colloidal systems, and for developing biological activities. This is also necessary for the rational design of CBS amphiphilic structure regarding to specific properties. The same approach can also be applied for other required features as the compound stability, toxicity, and biodegradability. [less ▲]

Since the mid-1970s, infrared remote sensing at the Jungfraujoch, Switzerland, has been performed in response to the need to measure the concentrations and assess the seasonal and long-term changes of an increasing number of atmospheric constituents. Currently, the vertical column abundances of over 20 telluric gases are being monitored, based on the analysis of solar spectra recorded regularly between 2 and 14 microns, using two high-resolution Fourier transform spectrometers. In this paper, emphasis is placed on those activities more specifically performed within the framework of the NDSC (Network for the Detection of Stratospheric Change) whose objectives are briefly described in the introduction.

In this paper, we offer a short overview of a number of methods that have been reported in the computational-mechanics literature for quantifying uncertainties in engineering applications. Within a probabilistic framework, we describe the characterization of uncertainties using mathematical statistics methods, the propagation of uncertainties through computational models using either Monte Carlo sampling or stochastic expansion methods, and the sensitivity analysis of uncertainties using variance- and differentiation-based methods. We restrict our attention to nonintrusive methods that can be implemented as wrappers around existing computer programs, thus requiring no modification of the source code. We include some recent advances in the propagation and sensitivity analysis of uncertainties that are characterized by arbitrary probability distributions that may exhibit statistical dependence. Finally, we demonstrate the methods integrated in the proposed overview through a nonlinear engineering application relevant to metal forming. [less ▲]

This paper reviews a broad range of performance evaluation tools available for social enterprises and compare them. Therefore we develop an analytical framework based on the specificities of social enterprises and on performance management theory. This framework incorporates the most relevant criteria that will allow to determine whether a tool includes the ideal characteristics to evaluate performance in social enterprises and to what extent. Three of the most representative and widespread tools, the balanced scorecard, the social return on investment and the global reporting initiative framework, are then studied and compared through this analytical framework.
