Institut de Technologie du Cambodge , also known as Techno , is the only institution in Cambodia whose mission is to form superior and middle managers whom private companies need. It is so in narrow relation with the industrial world directly involved in the regional context. It benefited from a frame of action which allowed ITC to start without time losing. The ITC was founded in 1964. The first objective is to prepare executives arranging qualities allowing the students to face the labour market in Cambodia and in the region. The quality of the scientific and technical educations, the practice of foreign languages predispose them to a regional brilliance.ITC elaborated new educational programs in accordance with the socio-economic reality of the country and the region. On this subject, the qualitative analysis of the employment market in Cambodia which is in full reconstruction, and in the most active region of the globe puts the following sectors in first priority : Public works and Building Prospection, production and energy distribution Transformation of agricultural products and food technology Drinking water and sanitation Industrial maintenance Telecommunications Automatic systems Agricultural hydrology and irrigation Electronics Information Technology Wikipedia.

A Zeta converter is a fourth-order DC-DC converter made up of two inductors and two capacitors and capable of operating in either step-up or step-down mode. Compared with other converters in the same class, such as Cuk and SEPIC converters, the Zeta converter has received the least attention, and more importantly, its dynamic modeling and control have never been reported before in the literature. This paper presents dynamic modeling and control of a Zeta converter operating in Continuous Conduction Mode (CCM). The State-Space Averaging (SSA) technique is applied to find small-signal linear dynamic model of the converter and its various transfer functions. Based on the derived control-to-output transfer function, the PWM feedback controller is designed to regulate the output voltage. Results show that the converter exhibits good performance in steady state and during a step-load change. © 2010 IEEE.

The aim of the current study was to determine, via reverse transcription quantitative polymerase chain reaction (RT-qPCR) analysis, the effect of oregano essential oil (Origanum heracleoticum) and carvacrol, its major component, on the expression of virulence-associated genes in enterohaemorrhagic Escherichia coli (EHEC) O157:H7 ATCC strain 35150. Both oregano oil and carvacrol demonstrated their efficacy firstly, by inhibiting the transcription of the ler gene involved in upregulation of the LEE2, LEE3 and LEE4 promoters and of attaching and effacing lesions and secondly by decreasing both Shiga toxin and fliC genes expression. In addition, a decrease in luxS gene transcription involved in quorum sensing was observed. These results were dose dependent and showed a specific effect of O. heracleoticum and carvacrol in downregulating the expression of virulence genes in EHEC O157:H7. These findings suggest that oregano oil and carvacrol have the potential to mitigate the adverse health effects caused by virulence gene expression in EHEC O157:H7, through the use of these substances as natural antibacterial additives in foods or as an alternative to antibiotics. © 2014 FEMS.

Millions of people around the world are currently living under the threat of developing serious health problems owing to ingestion of dangerous concentrations of arsenic through their drinking water. In many places, treatment of arsenic-contaminated water is an urgent necessity owing to a lack of safe alternative sources. Sustainable production of arsenic-safe water from an arsenic-contaminated raw water source is currently a challenge. Despite the successful development in the laboratory of technologies for arsenic remediation, few have been successful in the field. A sustainable arsenic-remediation technology should be robust, composed of local resources, and user-friendly as well as must attach special consideration to the social, economic, cultural, traditional, and environmental aspects of the target community. One such technology is in operation on the Indian subcontinent. Wide-scale replication of this technology with adequate improvisation can solve the arsenic crisis prevalent in the developing world.

Watershed management and hydrological modeling require data related to the very important matter of precipitation, often measured using rain gauges or weather stations. Hydrological models often require a preliminary spatial interpolation as part of the modeling process. The success of spatial interpolation varies according to the type of model chosen, its mode of geographical management and the resolution used. The quality of a result is determined by the quality of the continuous spatial rainfall, which ensues from the interpolation method used. The objective of this article is to review the existing methods for interpolation of rainfall data that are usually required in hydrological modeling. We review the basis for the application of certain common methods and geostatistical approaches used in interpolation of rainfall. Previous studies have highlighted the need for new research to investigate ways of improving the quality of rainfall data and ultimately, the quality of hydrological modeling.

This paper deals with a numerical investigation of the behavior of a new joint typology to connect continuously composite beams in bridges. This beam-to-beam joint consists of butt-plates and headed stud anchors connected to a transverse concrete beam. It has been designed and tested under fatigue and monotonic loading. To describe the joint behavior, a general 3D model is required. However, due to the nonlinearities involved (plasticity, cracking, contact, friction, etc.) the convergence of the iterative process is very difficult to reach with such a model. For an accurate interpretation of the test results and a better understanding of specific local behavior, not accessible to measurement, an equivalent 2D finite element model has been proposed to approach the actual 3D problem. After calibration against experimental data, performances of this 2D model have been illustrated through two studies: the parametric influence of the butt-plate thickness and the internal force transfer mechanism in the joint. © 2014 Elsevier Ltd.
