Abstract: A prenatal screening system includes a wet-laboratory arrangement and a data processing arrangement to exchange instructions and data with the wet-laboratory arrangement. The data processing arrangement includes a database arrangement storing genetic information accessible to one or more algorithms executable on the data processing arrangement. The wet-laboratory arrangement collects one or more maternal blood samples from a pregnant mother. The wet-laboratory arrangement isolates free fetal DNA fragments present in cell-free DNA derived from plasma of the one or more maternal blood samples. The isolation utilizes baits based upon coordinates of cell-free fetal DNA fragment specific end-points, and the data processing arrangement analyses the isolated free fetal DNA and compares with one or more DNA templates stored in the data processing arrangement for determining an occurrence of one or more biological characteristics of fetal DNA present in the one or more maternal blood samples.

Abstract: A prenatal screening system including a wet-laboratory arrangement and a data processing arrangement to exchange instructions and data with the wet-laboratory arrangement. The data processing arrangement includes a database arrangement in which is stored genetic information accessible to one or more algorithms executable on the data processing arrangement. The wet-laboratory arrangement collects one or more maternal blood samples from a pregnant mother. The wet-laboratory arrangement isolates free fetal DNA (ffDNA) fragments present in cell-free DNA (cfDNA) derived from plasma of the one or more maternal blood samples.

Abstract: A solar powered distillation system without the need for any moving parts. Air from the atmosphere enters an evaporator (FIG. 2. parts 1,2, and 4) and passes over seawater (FIG. 2., contained in part 3) that is heated by sunlight. As the air increases in temperature and humidity, it becomes less dense. The air then enters a condensation structure (FIG. 2, part 6). Buoyancy forces allow the air to rise through the condensation structure and exit to the atmosphere through an outlet at the top of the condensation structure. While passing through the condensation structure, the air loses heat energy to the structure and water vapor condenses on its inner surface. The condensation then flows down the inner surface of the condensate collector into a container of fresh water (FIG. 2, part 7). The distiller can also be heated by a source of energy other than the sun, and can be used to distill volatile liquids other than water.
