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.

Rice is a primary food source, vital vehicle in dealing with food security and eradicating poverty. In Benin rice is becoming increasingly important and its production and processing tasks are divided on the basis of gender, with women being responsible for much of the drudgery involved in processing. To have an overview of gender and socio-economic dimensions of local rice processing in Benin, a study was conducted in the north and south of Benin with 240 smallholder rice processors randomly selected. In addition to structured interviews and weekly report sheets, the participatory assessment on sustainable livelihood approach was used to appreciate the different states of their financial, social, human, natural and physical capitals assets. Rice processors are mostly women (67% in the whole sample). Men are more representative in white rice processing while women are more representative in parboiled rice processing. Women rice processors have less acces to formal learning source and have bad practices during white rice processing. The traditional rice parboiling methods that don’t lead to good quality rice is prevalence. The main actors of local rice commercialization are the rice producers; the bodies of the Ministry of Agriculture; Famers Organisation and smallholder local rice processors who are generally young women. During local rice commercialization, women are more representative in the sale without contract in the processing village while men are more representative in the sale under a contract. The overall state of capitals is low with better scores in human, physical and natural capitals stocks for men and in social capital for women. [less ▲]

SPICAV/SOIR is a suite of three spectrometers in the UV and IR range flying on ESA Venus Express orbiter, dedicated to the study of the atmosphere of Venus : UV (110-320 nm), Vis-Nir (0.65-1.65 µm), and mid IR (2.3-4.4 µm). The UV spectrometer discovered a high altitude layer of SO2 ( 85-105 km), apparently correlated with the density of haze particles. Ozone is detected for the first time in the atmosphere of Venus. The night side γ and δ bands of NO intensities are maximal at 2 am (influence of super-rotation), while the O2 emission mapped simultaneously by Virtis peaking at 95 km altitude ( 10 km below NO emission) is centered at midnight, a puzzle for general circulation models. The hot hydrogen component of the exosphere, extending at more than 30,000 km, is variable. The SPICAV VIS-IR sensor (0.7-1.7 μm, resolution 0.5-1.2 nm) employs a pioneering technology: acousto-optical tunable filter (AOTF). Day side observations indicate a variable latitude distribution of cloud top altitude (decreasing toward the pole) and water vapor mixing ratio. The SOIR spectrometer is a new Solar Occultation IR spectrometer in the range λ=2.2-4.3 µm, with a spectral resolution λ/Πλ>20,000, the highest ever flown in a planetary mission. This new concept includes a combination of an echelle grating and an AOTF crystal to sort out one order at a time. Vertical profiles of CO, HDO, H2O, HCl, SO[SUB]2[/SUB], CO[SUB]2[/SUB] isotopes and temperature are regularly retrieved, as well as aerosols. The CO mixing ratio (80-130 km), a tracer of atmospheric exchange from thermosphere to lower atmosphere, is 10 times less than the VIRA model prescription, showing also some time variability.
