Is weight gain after smoking cessation inevitable?

Weight gain after smoking cessation was studied in a naturalistic setting where (1) all smokers quit and (2) risk factors for postcessation weight gain were modified. Participants were 332 military recruits (227 men, 105 women), 86 of whom were smokers who quit during 6 weeks of basic training. Results showed no significant weight changes for smokers who quit. Pretest smoking rates and feat of weight gain were unrelated to changes in weight. Results suggest that an intensive program that limits access to alcohol and foods that are high in fat and that increases physical activity can attenuate weight gain after smoking cessation.

Fluidisation and gas combustion in a rotating fluidsed bed

The background against which this novel type of high intensity combustor is being developed is described.Some of design, development and operating problems involved are reported. Conditions for satisfactory fluidisation of the particles and combustion of propane within a rotating fluidised bed are outlined.Running experience shows that stable, complete combustion of propane can be sustained at intensities exceeding 85 MW/m³ of bed particles when a centripetal acceleration of ten times gravity is applied to a shallow bed of particles without an unacceptable pressure drop.     

Database Support for Versions and Alternatives of Large Design Files

We identify the roles played by design versions and alternatives in an engineering database. The obvious way to implement versions is to maintain each in a separate collection of files. Because several versions must be kept on line in a design environment, the approach leads to large disk requirements. We develop B-tree-based storage structures to encode versions as ``negative' differential files. Our objective is to keep the disk requirements small. We discuss the effect of enormous amounts of cheap archival storage (write-once optical digital disks) on the proposed structures. We have implemented versions in the Wisconsin storage system (WiSS), an experimental database component developed at the University of Wisconsin-Madison.     

Increased disruption of sperm plasma membrane at sperm immobilization promotes dissociation of perinuclear theca from sperm chromatin after intracytoplasmic sperm injection in pigs

The effects of sperm-immobilization methods on decondensation of sperm chromatin and retention of subacrosomal sperm perinuclear theca (SAR-PT) after intracytoplasmic sperm injection (ICSI) were examined in pigs. Sperm membrane damage caused by different immobilization methods by rubbing with a micropipette without piezo pulses (R), or with a low (L) or high (H) intensity of piezo pulses while rubbing, was assessed by the time required for staining of sperm heads with eosin Y solution. The average time for staining of sperm heads immobilized by the R, L or H treatments was 76, 41 or 26 s, respectively. The fertilization rate following ICSI was increased by sperm immobilization by piezo pulses compared with R, but increased intensity of pulses from L to H did not cause further improvements (29, 48 and 47%, respectively). An immunofluorescence study revealed that H immobilization promoted the dissociation of SAR-PT from sperm chromatin compared with L and R, and it increased the frequency of male pronuclear formation in which chromatin appeared uniformly decondensed. With in vitro fertilization (IVF), SAR-PT disassembled coordinately with sperm chromatin decondensation and it was not detectable around male pronuclei. This was different from most of the oocytes after ICSI in which remnants SAR-PT were detected adjacent to male pronuclei. We concluded that increased damage on the sperm plasma membrane at immobilization improved fertilization rates and decondensation of sperm chromatin after ICSI due to the accelerated dissociation of SAR-PT from the sperm nucleus. Also, the behavior of SAR-PT after ICSI was different from that observed in oocytes after IVF.     

Pup: An Internetwork Architecture

Pup is the name of an internet packet format (PARC Universal Packet), a hierarchy of protocols, and a style of internetwork communication. The fundamental abstraction is an end-to-end media-in dependent internetwork datagram. Higher levels of functionality are achieved by end-to-end protocols that are strictly a matter of agreement among the communicating end processes. This report explores important design issues, sets forth principles that have guided the Pup design, discusses the present implementation in moderate detail, and summarizes experience with an operational internetwork. This work serves as the basis for a functioning internetwork system that provides service to about 1000 computers, on 25 networks of 5 different types, using 20 internetwork gateways.     

The process gas chromatography of fatty acid distillation streams. I. Analytical chemistry

It was decided to build a process gas chromatograph to monitor the fatty acid stills. The initial work led to the development of phosphoric acid treated polyester columns for the GLC of unesterified fatty acids. The design and construction of a process analyzer for the fatty acid stills was then begun. When this gas chromatograph was completed, it was used to monitor the still. Chromatograms of the fatty acid streams are shown and discussed. Quantitative results are compared to those obtained by conventional methyl ester analysis. Work with inert support column packings is also described.
