Psychological and physiological stress impacts information processing at many levels, from attention and perceptual processes to reasoning and decision-making to motor execution. These effects can be highly adaptive, resulting in optimal performance. However, these effects can also result in serious degradation of performance, leading to human errors that often contribute to accidents. In this paper we review the variety of detrimental effects stress can have on different stages of information processing and provide examples of how these deficits can lead to accidents in motor vehicle operation and aviation.

Japanese companies, particularly Toyota, first began building quality into their products and becoming lean. Consequently, researchers associated with the international motor vehicle industry initially identified the “lean” manufacturing paradigm in the US automobile industry. Building upon their successes, the US aerospace industry initiated a study to ascertain whether a similar initiative focused on launch vehicles and spacecraft would bring value to military and commercial aerospace stakeholders in their ongoing efforts to be lean. This paper presents the findings of this investigation. It explores the relevance and value of the lean concepts to the US defense launch vehicle, spacecraft, and space operations industries, and it ascertains if there is interest within space industry firms in establishing a lean initiative similar to that of the automotive industry. Further, the relevance of lean manufacturing to other industries is considered.

In the Annaba plain (Northeast of Algeria), the anthropogenic activities have imposed serious unfavorable impacts on hydraulic, hydrochemical and biological balances that influence the socio-economic future of this area. A hydrochemical analysis was performed in 29 wells distributed over the whole of the plain region during the period of high water (December 2013) to assess the quality of groundwater for its suitability for irrigation. Several parameters were analyzed such as pH, TDS, Ca +2, Mg +2, Na+ , K+ , HCO3 - , Cl- and SO4 - . Analysis of results suggests that groundwater in the study area has the same qualities; however the observed degradation reflects a change in the water quality, and the SAR values vary from 0.08 to 16 with an average of 1.3. The US salinity laboratory, Wilcox, and percentage Na+ it suggest that the majority of groundwater samples are not good for irrigation.
