The present invention relates to blood-free-diets for malaria mosquito vectors that support ovarian development, egg maturation and fertility, as well as low progeny larval mortality, and normal development of offspring into adult mosquitoes.

The formulated diets comprise supplements of physiological concentrations of several different human GPCR ligands and shown to be an effective artificial meal, free of blood that mimics a vertebrate blood meal and represents an important advance for the sustainability of Anopheles mosquito rearing in captivity.

The present invention is in the domain of genetic engineering, parasitology, entomology medicine, pharmaceuticals and diagnose.

The present invention relates to a door frame, particularly a door frame for a pre-hung door assembly, which is foldable to minimize storage space and to allow for enhanced logistic efficiencies. The door frame contains parallel, spaced apart, vertical jambs and a horizontal header connecting the top ends of the jambs. Each of the jambs and the horizontal header contains a front section and back section that are hingedly joined so that then can be folded on to each other. The hingedly joined front and back sections allow the door fame to be foldable to minimize space occupied during storage.

A window and door frame system comprising members that fit together to enable a wide variety of window and door frame configurations and sizes to be constructed. The system comprises interlocking components that can be arranged in a variety of spacing combinations to enable building of frames in different configurations with a small set of components.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly. The sash includes at least one magnet. The sash is slideably engaged with the frame. The at least one screen assembly includes a roller assembly, a control bar, and screen material attached to the roller assembly and the control bar. The roller assembly is substantially hidden from view. The control bar includes a ferromagnetic material. The screen assembly is configured to apply tension to the screen material to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly under a tension applied to move the control bar away from the roller assembly. The control bar automatically engages the at least one magnet of the sash when the sash is in the closed configuration to attach the control bar to the sash.

A mullion is adapted for use in a narrow stile door system. The mullion is a three-section mullion with top and bottom hollow mullion tubes and an I-shaped centerpiece. The top and bottom hollow mullion tubes have a first outside width and first outside depth and a second inside width and second inside depth, the second inside width and depth defined by the inside of the hollow tube walls. The I-shaped centerpiece is connected to and fixed in between the top and bottom mullion tubes. The I-shaped centerpiece comprises a thin middle portion and top and bottom flanges, and top and bottom insert portions connected to the top and bottom flanges, and the top and bottom insert portions having a third width and third depth that are smaller than the second inside width and depth of the top and bottom hollow mullion tubes, with the insert portions adapted to be inserted into the hollow portion of the top and bottom mullion tubes and fixed therein.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.
