In order to evaluate the effect of chromium content in carbon steel on corrosion resistance materials, behavior 1Cr and N80 steels was investigated this study by immersion weight loss method under three different CO2 partial pressure temperature conditions formation water for 72, 168 336 h. Detailed material surface morphological characterization performed scanning electron microscopy (SEM), en...

HE AIM OF WIND TURBINE SYSTEMS DEVELOPMENT is to continuously increase output power. A few years ago, the rated output power of production-type units reached 200 kW. By 1999, the average output power of new installations climbed to 600 kW. The largest series production units today are specified to deliver 1.5-MW output power (Table 1). It is anticipated that in the near future, power rating of ...

Oil well stimulation, usually done with hot solutions of hydrochloric acid, may induce severe corrosion attack on production tubing, downhole tools and casing. Inorganic, organic and combinations of acids along with surfactants are used in a variety of well stimulation treatments. To reduce the aggressive attack of the acid on tubing and casing materials (N80 steel), inhibitors are added to the...

The premotor theory of attention postulates that during response preparation, attention shifts are elicited towards the goal of a prepared movement. Support for this claim comes from research demonstrating enhanced performance at the location of upcoming saccades. To investigate whether attention shifts occur towards effectors or goal locations during the covert preparation of unimanual movemen...

Behavioural studies have shown that when engaging in a visual task response facilitation to tactile stimuli at exogenously cued locations is diminished. Here we investigated behavioural and also neural correlates of tactile exogenous attention when participants either watched a visual stream (single task) or also detected targets in the visual stream (dual task). During the visual stream, tacti...

BACKGROUND A cross-sectional study has reported that nickel allergy is associated with endometriosis. However, causal studies of this association are limited. OBJECTIVE The objective of this study was to compare the prevalence of nickel allergy in women with and without endometriosis. METHODS We used a National Health Insurance Service (NHIS) sample cohort dataset that included approximatel...
