PROBLEMS RAISED BY NOXES CONTROL AT FCAW
Flux cored arc welding (FCAW) is applied due to its remarkable results and advantages (high productivity, joint quality etc) in various fields (industrial construction, naval, chemistry, petrochemistry etc.). FCAW disadvantages, mainly the emission of pollutants, can be counteracted by their rigorous control and local forced ventilation in the production. Control measures that can be used for measuring “in-situ” noxes resulting from the FCAW process are presented. Case studies are presented as well, containing data regarding two new tubular wire produced in order to be used with the flux cored arc welding process.
Determination of some Mechanical Characteristics by Vibration Testing of Welded Structures with Tubular Wire
Applicability of the welded structures in different operating conditions requires experimental research developed in conditions previously imposed for each punctual application. There are analyzed in this case, in terms of vibration testing, some welded joints made with usual tubular steel wire. This is the case of the type carbon steel plates S235 JR according to EN 10025, with a thickness of 3 mm welded with MIG/MAG welding process with R713 tubular wire with a diameter of 1.2 mm, using SelcoNeoMig 3500 equipment. By processing the received signal based on the vibrations response to determine the elastic modulus of the welded structure, which will then be compared both with the modulus value obtained by tensile tests, and with the theoretical value obtained. The results thus obtained will be the basis of design, in optimal conditions of the welded structures regarding the appropriate behavior to the demands imposed.
Critical Care Medicine Tutorials
CCMTutorials.com is a comprehensive, interactive website that introduces the reader to the field of critical care medicine. It includes both information in lecture format and clinical scenarios covering a variety of conditions that are commonly encountered in intensive care units. The website has six main subjects (introduction, problem oriented approach, respiratory failure, shock, renal failure, and sepsis), which are hierarchically subdivided into numerous smaller topics. Each topic has a main menu containing numerous subtopics. The discussion of each subtopic is one or more pages long, often with links to related subjects. The site is thorough and well organized, and has information for visitors of all levels of training. However, much of the information is introductory, and more experienced clinicians can expect a lower yield from the site than may medical students. 
 
CCMTutorials.com has much to offer the casual, interested viewer. However, the site only works well if one thinks like the author. Because it does not have a 'search' feature, the site can be quite difficult to navigate if one is looking for a topic that does not appear in one of the main menus. In addition, the clinical scenarios are superficial and brief. They do not allow any direct participation and often discuss only one point of interest before moving on to the next scenario. For help with these, or any other questions, there is a window that allows the visitor to e-mail a question to Dr Neligan (the author). 
 
The main disadvantage of CCMTutorials.com is that there is no information about the website itself. Although the site is clearly licensed to a physician at the University of Pennsylvania, no other information about the site's author is presented. Much of the information posted on the site is not referenced. There is no indication of how often the site is updated. Text is often written from the first person perspective, implying that we are getting only this author's opinion on a particular subject. This is substantiated by the author's acknowledgement that the 'tutorials are not peer reviewed'.
