Abstract: The invention relates to a process for removing 5poly(propylene oxide) from propylene oxide, comprising: a) sending a stream comprising propylene oxide and poly(propylene oxide) to a filtration screen having openings with an average diameter of at most 50 ?m; and b) sending the filtrate stream resulting from step a) to a membrane 10 having an average pore size of from 0 to 30 nm and recovering a permeate stream from the membrane as a purified propylene oxide stream.

Abstract: A fishing lure device attracts fish using sound, movement, reflection and appearance. The device includes an elongated main body having a front end, a rear end and a perimeter surface coupled to and extending between the front end and the rear end. A longitudinal axis extends through the main body between the front end and the rear end. At least one hook is attached to the main body. Each hook is configured to catch a fish thereon. A pair of panels is coupled to the main body. Each of the panels is angled upwardly and outwardly away from a top side of the main body. The panels are orientated in opposite directions with respect to each other and orientated perpendicular with respect to the longitudinal axis of the main body.

Abstract: The invention discloses the sequences of variant forms of alpha-fetoprotein transcripts that have been identified in human hemopoietic progenitors but not in differentiated mature cells. The variant forms of AFP (vAFP) cDNA sequences isolated from a multipotent hemopoietic cell line, K562, differ from the authentic AFP transcript, consisting of 15 exons, by lacking only exon 1. Instead of exon 1, vAFP transcripts use an additional one or two exons located in the 5?-untranslated region of the AFP gene. K562 expressed selectively vAFP, whereas a hepatocellular carcinoma cell line, HepG2, showed no detectable expression of vAFP. In normal adult tissues, vAFP transcripts is detected in the bone marrow, thymus and brain, but not the spleen, suggesting the expression occurs in normal hemopoietic progenitors. Moreover, CD34+Lin? hemopoietic stem/progenitor cells purified by flow cytometric sorting also express the variant transcripts.

Abstract: A wireless sensor and actuator network includes a number of wireless nodes, each of which may be connected to any one or combination of analog sensors, digital sensors, and actuators, and is powered by an autonomous power supply such as a battery or solar panel. Since autonomous power sources may not have sufficient voltage for powering many types of analog sensors, digital sensors, and actuators, power management techniques are used in the node and in the autonomous power supply as needed to enable effective and long life operation of the node and connected devices. These power management techniques include the use of a low impedance energy reservoir and a variable voltage boost converter whose output voltage magnitude, duration, and operating times are software configurable and controllable. The power management techniques are particularly useful for operating a wide range of different types of sensors and actuators.
