The author was part of the Rotating Air Seal repair development team. He assisted in the Repair Process Launch Review preparation, which entails evaluating technical data, identifying critical to quality key product characteristics, evaulating capital requirements, identification of tooling requirements and creating summary of operations
Juvenalia, or How I came to own a Blu-Ray of Point Break
Agony Klub and Publication Studio Vancouver are pleased to present Whitney Houston, vol. 2. A continuation of Whitney Houston, et. al., editor/author Casey Wei invites six writers to reflect on their relationship to popular music in film, keeping in mind that popular music has always been as much about the desire for an image as about the catchiness of a song. The resulting essays on Elliot Smith, Amélie, Real Genius, The Pixies, Drive, and The Conversation explore themes of time, love, and evolution.final article publishedReal Genius (1985
Identification and characterisation of the Arabidopsis thaliana cell wall proteome: unravelling novel cell wall proteins and new potential functions of the plant extracellular matrix
The application of the proteomic approach has facilitated efforts directed toward the mapping of the entire Arabidopsis cell wall proteome. Proteins were sequentially extracted from purified cell walls using 0.2 M CaC1(_2) followed by a urea buffer. The extracts were resolved via large format two dimensional polyacrylamide gel electrophoresis (2-D PAGE) and were visualised via Coomassie brilliant blue staining. The aim was to identify and characterise as many cell wall proteins as possible, with the hope of identifying novel cell wall proteins. Out of 325 spots visualised on the 2-D polyacrylamide gel, 144 gave a positive protein identification representing 104 different proteins. The identified proteins were divided into 3 categories. The first category included proteins that have been previously identified as plant cell wall proteins. The second category was designated to include novel cell wall proteins (hypothetical proteins) and the third category was made up of proteins, which had recognised functions, but had never hitherto been known to be secreted to the extracellular matrix. Among the identified novel cell wall proteins there were several that shared high homology with protein kinases. These proteins possessed all the characteristics of secreted polypeptides, such as the cleavable N-terminal signal peptide, and were found to lack both the transmembrane domain and the endoplasmic reticulum retention tetrapeptides (HDEL and KDEL). These observations suggested that, as in animal cells, plant cells had extracellular protein kinase activity (phosphorylation). This was supported by the recent discovery that plant cells secrete ATP to the extracellular matrix (Thomas et al., 2000). Verification of the occurrence of extracellular protein kinase activity was further strengthened by the identification of phosphorylated bona fide cell wall proteins and stress responses caused by the depletion extracellular ATP

Cell wall involvement in desiccation tolerance in the resurrection plant Craterostigma wilmsii
Bibliography: leaves 92-129.Resurrection plants have the unique capacity to revive from an air-dried state. In order to cope with desiccation, resurrection plants have to overcome a number of stresses, mechanical stress being one. This occurs when the cytoplasm shrinks creating tension between the plasma membrane and the cell wall. In leaves of the Craterostigma species, an extensive shrinkage occurs during drying as well as a considerable wall folding. It is thought that this folding is a well controlled process rather than a simple collapse and that the ability of the wall to fold is important for the viability of the tissues upon drying. The aim of this study was to characterize the cell wall architecture and composition in hydrated and dry leaves of C. wilmsii using microscopical and biochemical techniques. Calcium and hormone contents were also determined during drying. The development of anhydrous fixation for microscopy confirmed the important folding of the wall previously observed with chemical fixation. Using immunocytochemical techniques and a variety of well characterized antibodies, the nature and composition of wall polymers was investigated. There was nothing unusual in the wall composition of C. wilmsii leaves as compared with other dicotyledonous plants. The results show a significant increase of the hemicellulosic polysaccharide xyloglucan and of the unesterified pectins during drying with levels declining again during rehydration. In contrast no increase was observed in others polysaccharides such as ß (1-4) galactans and methylesterified pectins. Biochemical analysis allowed further characterization of cell wall composition of C. wilmsii. The data demonstrate marked changes in the pectic and hemicellulosic wall fraction from dry plants compared to hydrated ones. The most conspicuous change was a decrease in glucose content in the hemicellulose fraction of the dry plant. Together these findings show that dehydration causes important alteration of polysaccharides content in the cell wall of C. wilmsii. Such modifications might be involved in the modulation of the mechanical properties of the wall during dehydration. Furthermore calcium ions content was shown to increase in the cell wall of dry plants, this could also have a role in stabilizing the wall architecture. All these alterations might be under the control of auxin, an hormone whose content was shown to increase during dehydration
Interview with Whitney Roberts: Interview
The history of the video game industry is filled with many people and events that helped develop and design how video games are currently accessed and perceived. As with all things however, this history tends to be swept away through time, and the pillars that helped forge this industry slowly fade into nothingness. While the general populace is content to let this natural erosion occur, a passionate few dare to resist the degradation of what they love. They do this, not for fame or glory, but to preserve what they can of the phenomena that not only touched, but defined the lives of so many of us today. One such guardian of the history of video games is Whitney Roberts. Whitney Roberts a prime guardian with multiple ties to the coin-op industry, even in Chicago. Whitney hails from Louisville, Kentucky, and he collects, plays, and runs his own podcast. Whitney collects all sorts of coin-operated games, even some rare games such as the Red Donkey Kong. He does this partially out of his love for these machines, but also to help preserve these games as well as the arcade experience for future generations to enjoy. Whitney is an advocate for arcades and thinks everyone should experience the atmosphere of an arcade. One of his favorite arcades is the Logan Arcade. In addition to collecting, Whitney Roberts runs BrokenToken, a podcast that he does as a hobby. The podcast is Whitney’s way of informing people of the important work he is undertaking, yet still trying to keep an audience by putting a southern spin on the coin-op industry
Whitney Twins, Whitney Duals, and Operadic Partition Posets
We say that a pair of nonnegative integer sequences is Whitney-realizable if there exists a poset for
which (the absolute values) of the Whitney numbers of the first and second kind
are given by the numbers and respectively. The pair is said to be
Whitney-dualizable if, in addition, there exists another poset for which
their Whitney numbers of the first and second kind are instead given by
and respectively. In this case, we say that and are Whitney
duals. We use results on Whitney duality, recently developed by the first two
authors, to exhibit a family of sequences which allows for multiple
realizations and Whitney-dual realizations. More precisely, we study edge
labelings for the families of posets of pointed partitions
and weighted partitions which are associated to the operads
and respectively. The first author and Wachs
proved that these two families of posets share the same pair of Whitney
numbers. We find EW-labelings for and and use
them to show that they also share multiple nonisomorphic Whitney dual posets.
In addition to EW-labelings, we also find two new EL-labelings for
answering a question of Chapoton and Vallette. Using these
EL-labelings of , and an EL-labeling of introduced by
the first author and Wachs, we give combinatorial descriptions of bases for the
operads and . We
also show that the bases for and are PBW
bases.Comment: 37 pages, 20 figure
