AbstractA new concept, which combines existing fieldproven technology with new innovative features, has been evaluated as an attractive technique for collection and retrieval of tophole drill cuttings, excavated during offshore drilling. Simplified, the presented technique is based on using a collar that is thread on the drill string prior to the spudding in commences. The collar is fitted with a connecting hose and a pump that help suck the fluid and the excavated drill cuttings into settling and filtration bags. After collection of solids the bags are easily displaced. By its simplicity and efficiency the technology appears as an attractive solution for drilling wells in sensitive areas where a zero discharge regime of drill cuttings prevail.

The squaring of the circle is impossible, but it can be represented geometrically. One such construction is similar to a diagram used to analyze two early Norwegian cathedrals. Further investigation revealed that it was not quite that simple. However, this pursuit revealed some alternative, but related possibilities, including a way of combining 2 and 5 -albeit approximately.

We investigated coaches’ mindsets of athletic talent as conceptualised by Dweck (athlete talent mindset, A-TM) along with the athlete age at which they believe talent can be identified. We also looked at the age of talent identification in coaches of different A-TM. Using data collected as part of a survey conducted in Norway, the 3,830 participating coaches were men and women between 16 and 83 years of age. Overall, the coaches held a predominantly growth A-TM. However, older coaches, those not born in Norway, and coaches in athletics, gymnastics, and football were found to have a more fixed A-TM. Regarding their views about talent identification age, one fifth of the coaches believe that talent can be seen before 12 years of age, with football, gymnastics, and swimming coaches and those not born in Norway being more prone to detect talent at younger ages. Analyses also showed that the more fixed A-TM coaches believed that they could identify talented athletes at younger ages; however, not all of them reported such talent identification age views. These findings indicate that coaches’ A-TM and views regarding talent identification operate as two separate beliefs, which may be useful for understanding coaches’ early talent identification and development approaches.
