Two vessels from different sites of the Iranian Plateau, dating to the late 4th or early 3rd millennium BCE are presented aspalaeotechnological case studies. In the fractures of the vessels’ walls, interfaces left by added clay parts (enhanced inthe two illustrations) are quite recognizable. It is proposed that in both cases potters, in order to construct the bases, usedto make bowls comparable...

Reinfusion of shed blood during surgery could avoid the need for blood transfusions. Prior to reinfusion of the red blood cells, the shed blood must be washed in order to remove leukocytes, platelets, and other contaminants. Further, the hematocrit of the washed blood must be increased. The feasibility of using computational fluid dynamics (CFD) to guide the design of better centrifuges for pro...

Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues--such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz) than in smaller (12-oz) bowls, whereas introverted children were unaffected by bowl size (+5.6%, n...

Fall-risk factors were compared between older women who regularly participate in lawn bowls and controls. Participants were 74 healthy women age 60-75 yr. Postural stability, timed up-and-go score, isometric knee-extensor strength, reaction time, range of motion, and calcaneal broadband ultrasonic attenuation (BUA) were assessed. Bowlers and controls were similar in regard to mean age, height, ...

two fish. In the wild, kittiwakes have to learn to look for particular colours and patterns in the ocean to find the best place to fish. The researchers tried to recreate this for the captive birds by making them search for their food among a chequerboard of different coloured bowls. Chicks on the unrestricted fatty diet quickly learned which bowls contained food, but chicks on lean rations wer...
