Abstract: The present disclosure relates generally to roofing structures, for example, suitable for covering houses and other structures. The present disclosure relates more particularly to a roofing structure including a decking layer, a base layer, a cap layer, and a plurality of rails disposed over the cap layer. The base layer includes a plurality of strips that form seams including a first base layer seam. The cap layer also includes a plurality of strips that form seams including a first cap layer seam that is spaced from the first base layer seam. The rails include a first rail that is aligned with the first base layer seam and a second rail that is aligned with the first cap layer seam.

Abstract: A reverse osmosis system includes a membrane unit, an energy recovery device, high and low pressure inlet lines, and a concentrate line. The membrane unit has a membrane, an inlet for receiving a feed fluid, a permeate outlet for discharging a permeate fluid and a concentrate outlet for discharging a concentrate fluid. The energy recovering device has a turbine portion, a turbine inlet and a turbine outlet, a pump portion, a pump inlet and a pump outlet, a motor, and a motor control unit for controlling the motor. The low pressure inlet line is connected to the pump inlet for supplying the feed fluid at a low pressure. The high pressure inlet line connects the pump outlet with the inlet for supplying the feed fluid at a high pressure. The concentrate line connects the concentrate outlet with the turbine inlet for supplying the concentrate fluid to the turbine portion.

Abstract: The present disclosure describes methods of inserting lithium into an electrochromic device after completion. In the disclosed methods, an ideal amount of lithium can be added post-fabrication to maximize or tailor the free lithium ion density of a layer or the coloration range of a device. Embodiments are directed towards a method to insert lithium into the main device layers of an electrochromic device as a post-processing step after the device has been manufactured. In an embodiment, the methods described are designed to maximize the coloration range while compensating for blind charge loss.

Abstract: Methods and compositions for the prevention and treatment of recent and old dermatitis, especially psoriasis, using lecithin or a lecithin-rich extract. According to one embodiment, phospholipids constituting the lecithin are esterified by Omega 3-type polyunsaturated fatty acids, in particular by docosahexaensic acid (DHA) and eicosapentaenoic acid (EPA) or by an alkyl glycerol. The lecithin can be of marine origin, extracted from a marine organisms such as fish, shrimp, krill, zooplankton, algae, and phytoplankton, which are advantageous in that their phospholipids, especially phosphatidylcholine, are naturally esterified by Omega 3 fatty acids, and essentially by DHA and EPA.

Abstract: A toy hat, mask, puppet or the like on which fanciful animal, human or monster faces can be created by attaching discrete facial elements comprised of a nose, eyes, ears, cheeks and the like. They are made, in whole or part, from fabric materials of a "loop" fastening nature, which with selective parts may be transformed (intra-changed) to make different styled nose, ear, tongue, eyebrow and the like. These discrete formable parts along with the other inter-changeable parts may then be mounted to the "hook" fastening composite materials of the curved compound surface located in the area of the face, forehead and front scalp region of the toy and other like items. At least 50% of the area of this curved compound composite surface is covered by a "hook" material layer made up of an essentially non-extensively flexible "hook" of a woven and/or extruded product.
