Push/pull hemodiafiltration is characterized by alternate filtration and backfiltration, while sterile pyrogen-free dialysate is flowing through a hemodiafilter. During the filtration phase, uremic substances are eliminated not only by diffusive, but also by convective transport. During the backfiltration phase, dialysate is quickly pushed to the blood

AbstractTwo push‐pull‐cyclobutadienes 10b and 10c are prepared by reaction of two eq. of the corresponding acetylenes having electrondonating and electronaccepting groups (4) with one eq. of HBF4 to cyclic cyanine salts, followed by elimination of HBF4 with KOC(CH3)3.

Development of Push-Pull Ventilation
AIHAJ, 1985Push-pull ventilation (air is blown across a contaminant generation area toward an exhaust hood) can have distinct advantages over exhaust ventilation alone. It can control contaminant emission into the workplace better than exhaust only, and much less conditioned air must be exhausted so there are energy savings. This paper presents suggested push and

Push-pull electrostatic deformable mirrors
SPIE Proceedings, 2008Deformable membrane mirrors have a lot of advantages if compared with other adaptive optics devices such as bimorph mirrors, liquid crystal modulators, and thermal mirrors. Their properties are good optical power, low cost, limited power consumption, achromaticity and a good dynamic behavior. Their use in technological applications is limited by the

Push-Pull Laser-Atomic Oscillator
Physical Review Letters, 2007A vapor of alkali-metal atoms in the external cavity of a semiconductor laser, pumped with a time-independent injection current, can cause the laser to self-modulate at the "field-independent 0-0 frequency" of the atoms. Push-pull optical pumping by the modulated light drives most of the atoms into a coherent superposition of the two atomic sublevels ...

Push‐Pull and Schooling Investment
American Journal of Agricultural Economics, 1968U NITED STATES census data for 1960 are used in this study to reexamine the push-pull theories of migration. One contention is that the aphorism "last hired and first fired" applies to the least educated among regions as well as over the course of time. Those with least education are most influenced by depressed economic conditions within a region, and

Distributed energy resources are expected to radically change the way energy is produced and distributed through decentralised generation and storage. Current distributed energy models tend to hide the complexity of these systems in order to improve ease of use, while restricting people's participation to predefined roles of passive users who can ...

The “push–pull strategy” is based on a novel cropping system approach involving behavioral manipulation of insect pests and their natural enemies for integrated pest and weed management in farming systems. This technology works through integration of stimuli that act to make the main crop unattractive or unsuitable to the pests, the intercrop repels ...

Non-planar push–pull chromophores
Chemical Communications, 2010The development of a unique class of non-planar push-pull chromophores by means of [2 + 2] cycloaddition, followed by cycloreversion, of electron-deficient olefins, such as tetracyanoethene (TCNE), 7,7,8,8-tetracyanoquinodimethane (TCNQ) and 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F(4)-TCNQ), as well as dicyanovinyl (DCV) and ...
