Abstract Wild oat is a herbicide resistance-prone global weed species that causes significant economic losses in dryland and horticultural agriculture. As result, there has been research effort to control this species. A major impediment the seed coat-mediated dormancy of wild oat, which requires labor-intensive incision or puncturing coat initiate germination. This study defines most efficient...

The process of vaccination introduced by Jenner generated immunity against smallpox and ultimately led to the eradication of the disease. Procedurally, in modern times, the virus is introduced into patients via a process called scarification, performed with a bifurcated needle containing a small amount of virus. What was unappreciated was the role that scarification itself plays in generating p...

Infectious bovine keratoconjunctivitis (IBK) is a common corneal disease of calves that adversely affects animal welfare by causing pain and weight loss. Identifying behavioral indicators of pain and sickness in calves with IBK is necessary for designing studies that aim to identify effective means of pain mitigation. Consistent with principles of the 3Rs for animal use in research, data from a...

Anthyllis barba-jovis is a salt and drought tolerant evergreen shrub, native of the western-central Mediterranean coasts, with ornamental characteristics that make it worthy to be exploited for commercial use as an landscape plant. Therefore, present study aimed determine germination affected by seed-coat, temperature, photoperiod, seed storage period, first approach introduce species into flor...

INTRODUCTION The finishing and polishing phases are essential to improve smoothness and shining on the surface of acrylic resins used to make removable orthodontic appliances. A good surface finishing reduces roughness, which facilitates hygiene, prevents staining and provides greater comfort to the patients. OBJECTIVE The aim of this paper was to analyze the changes on surface morphology of ...

Mountain mahogany (Cercocarpus montanus Raf) is a useful reclamation species because it can occupy and improve poor soils. Literature regarding seed propagation of tbis species is var· ied and often contradictory, recommending stratification dura· tions of 14 to 90 days, and sulfuric acid scarification durations of none to 60 minutes. To assess variability in propagation require. ments among se...

Scarification of the skin is a possible route of entry for scrapie infectivity in sheep, and for Creutzfeldt-Jakob disease agent in humans within the context of occupational exposure to infected brain in the autopsy room or laboratory. The effectiveness of skin scarification routes as portals of entry for infectivity had not previously been tested experimentally but this study has shown that th...

The emission of the airborne particles from epoxy resin test sticks with different CNT loadings and two commercial products were characterized while sanding with three grit sizes and three disc sander speeds. The total number concentrations, respirable mass concentrations, and particle size number/mass distributions of the emitted particles were measured using a condensation particle counter, a...

Enright [(1995). Perception, 24 (suppl.), 32-33; (1996). Vision Research, 36, 307-312] described a simple piece of equipment for demonstrating a perceptual mechanism he called sequential stereopsis. The equipment requires an observer to set two textured targets seen behind a pair of small viewing ports to appear equi-distant. The principle upon which the apparatus depends is the use of textures...
