objective: the purpose of this study was to evaluate the dental movements of the labial segment and the canines during leveling and alignment using pre-adjusted appliances and light forces with the mbt technique. the effect of lacebacks on the horizontal movement of the first molars was also assessed. materials and methods: fourteen patients with a mean age of 14.08 years were selected for this...

Four decades ago in Silent Spring, Rachel Carson (1962) wove together a fabric of evidence suggesting that parts of the modern chemical revolution were having unintended consequences, undermining human and wildlife health in unexpected ways. At the time that fabric was more Chantilly lace than Afghan rug, with the scientific pattern defined as much by the holes as by the threads of connecting e...

Lace is liable to stretch as it is passed through the feed mechanism, in which a vision system is engaged to detect the changes of the motif and find the cutting path (river) across the lace pattern. The vision system has to work with many different lace patterns, sizes and tolerate misalignment, stretch and other distortions. A Fuuy Reasoning Rule-based technique is employed in order to overco...

John Whitworth Wallace: Characterization of arboviral disease in western North Carolina (Under the direction of Steven R. Meshnick) La Crosse encephalitis (LACE) is the most commonly reported mosquito-borne illness in North Carolina, and the annual incidence of LACE in NC is among the highest in the nation—North Carolina accounts for 25% of all LACE cases reported to the Centers for Disease Con...

BACKGROUND Death or urgent readmission after hospital discharge is a common adverse event that can be used to compare outcomes of care between institutions. To accurately adjust for risk and to allow for interhospital comparisons of readmission rates, we used administrative data to derive and internally validate an extension of the LACE index, a previously validated index for 30-day death or ur...

Geographic variation in the traits of a species is shaped by variation in abiotic conditions, biotic interactions, and evolutionary history of its interactions with other species. We studied the geographic variation in the density of the lace bug, Corythucha marmorata, and the resistance of tall goldenrod Solidago altissima to the lace bug herbivory in their native range in the United States an...

" Pre-release efficacy assessment of biological control of Chinese privet was evaluated by lace bug inoculation on privet. " 15 Pairs of adult inoculation significantly reduced leaf biomass by more than 59% compared to 0 and 3 lace bug pairs, while 3 and 9 pairs had no effect. " The percentage of leaf feeding damage is positively correlated with the density of lace bugs inoculated. " Increasing...

This led wider collaborations exhibition ‘Lace Unarchived’, held at Trent University intended reveal legacy art school, established in 1843, impa...

Cephalopods are renowned for changing the color and pattern of their skin for both camouflage and communication. Yet, we do not fully understand how cephalopods control the pigmented chromatophore organs in their skin and change their body pattern. Although these changes primarily rely on eyesight, we found that light causes chromatophores to expand in excised pieces of Octopus bimaculoides ski...
