 AbstractThis study aims to determine whether speed and agility exercises have a significant effect on improving catching abilities in roundball games. The method used in this study is the experimental method, with the independent variables being speed and agility, and the dependent variable is the round ball catching technique. The sample used in this study was 40 students - 19 public elementary school students and as a comparison for students at the base of the city of Bengkulu. The data collection instrument or tool used in this study is a 30-meter sprint, running back and forth with a distance of 10 meters with 4 times back and forth and throwing a catch into the target wall of 2 meters in 30 seconds. Based on the management and analysis of the data obtained, the results of this study are the initial test average of 42.65. agility 19.66 and catching 59.60 the average test finally speeds 56.14. Agility 5.06 and throw catch 7.20 - the average difference of 1.9. The conclusion of this study, judging from the data, is that speed and agility training have a significant effect on round ball catching. Keywords: exercise speed and agility

M. M., female; single, æt. 37; admitted into Dundee Asylum 24th December, 1874. Patient had been more or less insane for eight months, during which time she had frequently threatened suicide, and declared that she had often tried to poison herself, but could never succeed in doing so. Has been in the habit of taking laudanum freely, although the quantities consumed could never be ascertained, Has taken no solid food for three days, giving as a reason that she could not get it over, as she had swallowed the knob of a mirror, and which was sticking in her throat. Her friends assured me that this must be a delusion, as she swallowed fluids easily. The first medical certificate on patient's admission paper testified that she “is highly nervous and excitable, insists that she has swallowed a round ball of mahogany to destroy herself;” the second one that she “says she has swallowed something that will be sure to kill her, and although quite able to swallow, declares that she is not able to let over even a mouthful of water. She has various other delusions.”

AbstractIn 1939 Weyl showed that the volume of spherical tubes around compact submanifolds M of Euclidean space depends solely on the induced Riemannian metric on M. Can this intrinsic nature of the tube volume be preserved for tubes with more general cross sections $$\mathbb {D}$$ D than the round ball? Under sufficiently strong symmetry conditions on $$\mathbb {D}$$ D the answer turns out to be yes.
