Abstract: A reactor closed to the atmosphere and method using same for nitrate removal are disclosed.

Abstract: The present invention relates to a process for the selective removal of nitrates from ground water using a hybrid nanofiltration (NF)—reverse osmosis (RO) filtration system. The process generates product water that is low in nitrate and can be used for drinking, irrigation and other purposes, as well as waste water that is relatively low in salinity and can be safely discarded to sewage systems and recycled, e.g., for irrigation purposes.

Abstract: Embodiments of the invention are related to a method and a system for eyesight diagnosis. The system includes a vision test unit and a controller. The vision test unit includes at least one eye movement tracking unit configured to track the movement of a portion of the eye, at least one screen for visual stimulation and a shuttering unit configured to controllably block the field of view (FOV) of each eye separately. In some embodiments, the controller includes a processor and a non-volatile memory that store thereon instructions that when executed by the processor causes the controller to: display to a patient a first visual stimulation on the at least one screen, cause the shuttering unit to block the FOV of a first eye of the patient while unblocking the FOV of a second eye, receive a first signal indicative of the second eye movement of the patient from the at least one eye movement tracking unit and diagnose the patient's eyesight based on the received first signal.

Abstract: A method of attaching a cell or a membrane-coated particle-of-interest to a microtube is provided. The method comprising: co-electrospinning two polymeric solutions through co-axial capillaries, wherein a first polymeric solution of the two polymeric solutions is for forming a shell of the microtube and a second polymeric solution of the two polymeric solutions is for forming a coat over an internal surface of the shell, the first polymeric solution is selected solidifying faster than the second polymeric solution and a solvent of the second polymeric solution is selected incapable of dissolving the first polymeric solution and wherein the second polymeric solution comprises the cell or the membrane-coated particle-of-interest, thereby attaching the cell or the membrane-coated particle-of-interest to the microtube.
