The paper presents 15 years of research conducted on the Bremen Autonomous Wheelchair “Rolland”. Rolland is a mobility assistant for the handicapped and the elderly. The paper presents the different versions of Rolland that were built over the years, as well as the special input devices that are used with Rolland. Contributions were made to the state of the art in the areas of self-localization...
This study investigated potential carry-over effects of increased growth rates prior to breeding at seven months age on mammary glands two-year-old ewes bearing one or two lambs, and examined the association between ewe structures their progeny. Ewe live weight ultrasound measures were recorded 119 days pregnancy, 29 lactation (L29), weaning progeny (L79) in 64 selected from treatments. The hea...
Variation in ovulation rate of ewes was studied with particular reference to the heterosis effect in a 3-breed (Dorset Horn, South Australian Merino, Corriedale) experimental sheep population. For the population as a whole, heterosis effect on the young (1 1/2 year-old) ewes (+0.17 k 0.06** ova, or 14.5%) was similar to that on the mature (5 1/2 year-old) ewes (+0.19 f 0.06** ova, or 12.5%), in...
Three-hour milk production measurements determined by machine milking at 3-d intervals throughout a 63-d lactation period were used to describe lactation curves for crossbred ewes lambing at 1 and 2 yr of age and rearing single and twin lambs. Age of ewe, type of rearing, and day of lactation affected (P < 0.05) milk production. Over the 63-d lactation, average daily milk production was 2.56 an...
Mating behavior is known to be heritable in several species, but it is not known if selection schemes for ewe reproductive traits affect mating behavior of rams. Therefore, our objectives were to determine if divergent (high vs low index) selection of a female reproductive trait (lambs born divided by age of ewe minus one) affects mating behavior patterns of male offspring during training to se...
A case of a bilateral simultaneous traumatic obturator dislocation of both hip joints in an 18-year-old young man following a traffic accident is presented. We reduced the dislocated femoral heads immediately under general anesthesia followed by passive and active exercises and early full-weight bearing mobilization. After 5 years, the result was excellent.
A 3-yr study was conducted to comprehensively evaluate Columbia, Suffolk, USMARC-Composite (Composite), and Texel breeds as terminal sires in an extensive rangeland production system. The objective was to estimate breed-of-ram effects on ewe fertility, prolificacy, and dystocia, and sire breed effects on lamb survival and growth until weaning at approximately 132 d of age. Data were from 22 Col...
Methods Thirty four patients were enrolled: twenty two males, twelve females, age between 15 days and 80 years old (mean 38 years old) with diagnosis of cardiac mass underwent echo and CMR before biopsy or surgery. Echo gradient cine images in multiple views, T1 and T2 weighted sequences, and additional information derived from first pass perfusion imaging and inversion recovery post gadolinium...
