The petition references almost 500 scientific studies, most of which have been peer reviewed, that starkly illustrate the widespread dangers from lead ammunition and fishing tackle. Lead is an extremely toxic substance that is dangerous to people and wildlife even at low levels. Exposure can cause a range of health effects, from acute poisoning and death to long term problems such as reduced reproduction, inhibition of growth and damage to neurological development.

Their small size, durability, long lifetime, and cool emitting temperature are more suitable for plant based uses than many other light sources.This project aims to investigate energy use efficiency and photosynthesis with the evaluation and improvement of protected horticulture system. At the initial phase the effects of different supplemental light including LED light on plant growth and photosynthesis in lettuce have been studied, the higher luminous efficiency and positive impact for plant’s growth showed the great potential of LED facilities compared with other artificial light and indicated that it is the most appropriate light resource at this stage. Claims of 50% energy savings for similar biomass yields are now obtained in the study.

Or, does Fox News’s Ocasio Cortez obsession come from a darker place? Some call it “white anxiety,” while others, like myself, call it white supremacy. Fox News has a history of stoking racial divisions. Just take a look at Tucker Carlson and Laura Ingraham, who have used their shows to warn viewers about the “browning” of America..

A new imaging contrast agent is reported that provides an increased fluorescent signal upon application of ultrasound (US). Liposomes containing lipids labelled with pyrene were optically excited and the excimer fluorescence emission intensity was detected in the absence and presence of an ultrasound field using an acousto fluorescence setup. The acousto fluorescence dynamics of liposomes containing lipids with pyrene labelled on the fatty acid tail group (PyPC) and the head group (PyPE) were compared.

He to me, didn really stand out style wise, yet it was funny because he commented on the fact that I would wear the latest sneakers, and that I had style. So, looking back, I see this was a young lad who didn own his. But it crystal clear to me, that I own mine..

Steve Hall, creator and editor of industry blog Adrants, wrote in 2008 that most of the “viral” videos then (particularly the “guys backflip into jeans” clip that ended up being part of a Levi’s campaign) were, in fact, advertisements. And earlier this year, another tattoo related fake viral video was discovered to be a marketing gimmick from Ray Ban. Fake virility isn’t limited to YouTube; often, we find commercial entities trying to “push” supposedly non commercial content on platforms such as Digg, Facebook and Twitter..
