In a generic spacetime massless field propagates not just on the surface of forward lightcone source, but in its interior. This inside-the-lightcone "tail radiation" is often described as having "scattered" off curvature. this work, we study propagation such tail radiation for compact, static, spherically symmetric weak-field (i.e. low density) mass distribution that well line-of-sight (LOS) be...

Amputation of the larval tail of Xenopus injures the notochord, spinal cord, muscle masses, mesenchyme, and epidermis, induces the growth and differentiation of cells in those tissues, and results in tail regeneration. A dorsal incision in the larval tail injures the same tissues and induces cell growth and differentiation, but never results in the formation of any extra appendages. The first s...

Syndrome de la queue de cheval. A propos de 4 cas.  Les auteurs rapportent quatre observations cliniques concernat des malades dont les pre­miers symptomes se manifesterent par des al­gies longitemps considerees comme "sciatique·s".  L' etude neurologique de ces cas demontrait qu'en realite "les algies sciatiques" n'etaient que des signes mono ou pluri-radiculaires en rapport avec un syndrome...

The long term aim with this study was to identify predictors or early indicators of tail biting outbreaks using registrations from electronic feeders. This study is based on information about daily frequency of feeder visits (DFV) and daily feed consumption (DFC) recorded in electronic feeders from 460 noncastrated boars in tail biting pens (TB pens, n = 21) and matched control pens (Con pens, ...

Tail docking of piglets is a routine procedure on farms to control tail-biting behaviour; however, docking can cause an acute stress response. The objectives of this research were to determine the stress responses to tail docking in piglets and to compare two methods of tail docking; cautery iron (CAUT) and the more commonly used blunt trauma cutters (BT). At approximately 6 days of age, piglet...

background and objective: due to the presence of some evidence for anti-diabetic and antioxidant activity of tribulus terrestris (tt), this study was designed to investigate the anti-nociceptive effect of tt in streptozotocin-diabetic rats using formalin test and hot tail immersion tests. materials and methods: rats were divided into control, tt-treated control, diabetic, sodium salicylate (ss)...
