At the last decade of the 20th century, Womack et. Al introduced Lean concept to the industrial world. Since 1990 up to now, existed studies mostly have focused on lean production in the step of manufacturing, but in this research leanness concept has developed in the plant life cycle. In this paper leanness concept will be described as elimination of wastes in the phases of investment, plant d...

Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...

N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide was used as a selective sensing material in the PVC membrane to construction of a new chromium ion selective electrode. This liquid membrane electrode worked well with a Nernstian response of 19.7 ±0.4 mV decade-1 of Cr(III) in a wide dynamic concentration range of 8.0× 10-6-1.0×10-1 M. The electrode had relatively short response time ...

the construction industry is a major consumer of new materials. given that material production for construction work accounts for a significant percentage of all energy consumed nationally in newly developing countries, it becomes vital that the construction industry strives to reduce waste at all stages of construction. however, the importance of these construction wastes in terms of types and...

Kish Island is a popular tourist destination in Iran, and tourism plays an important role in its economy. The volume of waste produced in the island has increased given the construction of numerous industrial projects over the past decade, as well as an increase in the tourist population. This expansion signals a need to create new methods of waste disposal. Environmental Impact Assessment (EIA...

Objectives: Because of the high rates of accidents, the construction industry has become a hazardous industry in Iran and therefore paying more attention is required. This paper investigates safety management in construction companies for improving workers’ safety as one of the ergonomics aims. Methods: In order to survey the safety management in construction companies a questionnaire was pr...

The launching of the JOT provides a welcome opportunity to resume the Eiffel column that ran for many years in JOOP from 1998 (edited first by Rock Howard from whom I took over in 1998). It will run pretty much like its predecessor, with a mix of contributions by guest columnists and by me, and a mix of topics — from language matters to methodological issues of object-oriented software construc...

a:4:{s:10:"Background";s:2314:"The research made on stem cells through the last decade and following that the great achievements made applying stem cells in treating vast number of diseases have turned the issue of Cord Blood collecting and saving (cryopreserving) to a critical one. A prompt demand and access to stem cells and applying them in treating a wide range of terminal diseases have led...

Sign languages (SL) require a fundamental rethinking of many basic assumptions about human language processing because instead of using linear speech, sign languages coarticulate facial expressions, shoulder and hand movements, eye gaze and usage of a three-dimensional space. SL researchers have therefore advocated SL-specific approaches that do not start from the biases of models that were ori...

Construction Grammar has reached a stage of maturity where many researchers are looking for an explicit formal grounding of their work. Recently, there have been exciting developments to cater for this demand, most notably in Sign-Based Construction Grammar (SBCG) and Fluid Construction Grammar (FCG). Unfortunately, like playing a music instrument, the formalisms used by SBCG and FCG take time ...
