Report presenting an investigation to determine the effect of wing profile on the transonic aerodynamic characteristics of rectangular and triangular wings with aspect ratios of 3. Five wings were compared over a range of Mach and Reynolds number. Results regarding the rectangular and triangular wings and use of transonic area rule are provided

PARTICIPANTS: 544 Electric Powered Indoor/outdoor wheelchair (EPIOC) users. INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: Demographic, clinical/diagnostic details of EPIOC recipients including pain, (kypho)scoliosis and ventilators. Technical features including specialised (adaptive) seating (SS), tilt in space (TIS), and modified control systems. Factors were related to age groups: 1 (0-15), 2 (16-24), 3 (25-54), 4 (55-74) and 5 (75+). RESULTS: 262 men mean age 41.7 (range 8-82, sd 20.7) and 282 women mean age 47.2 (range 7-92, sd 19.7) years were studied. Neurological/neuromuscular conditions predominated (81%) with cerebral palsy (CP) (18.9%) and multiple sclerosis (16.4%). Conditions presenting at birth or during childhood constituted 39%. 99 had problematic pain, 83 a (kypho)scoliosis and 11 used ventilators. SS was provided to 169 users (31%), the majority had CP or muscular dystrophy. TIS was used by 258 (53%). Younger people were more likely to receive TIS than older ones. Only 92 had SS and TIS, mean age 29 (range 8-72, sd 17.8) years. 52 used modified control systems. CONCLUSIONS: The diversity of EPIOC users across age and diagnostic groups is shown. Their complex interrelationships with these technical features of EPIOC prescription are explored. Younger users were more complex due to age-related changes. This study provides outcomes of the EPIOC prescription for this heterogeneous group of very severely disabled people

Global Positioning System Time Transfer Receiver (GPS/TTR) prototype design and initial test evaluation

Time transfer equipment and techniques used with the Navigation Technology Satellites were modified and extended for use with the Global Positioning System (GPS) satellites. A prototype receiver was built and field tested. The receiver uses the GPS L1 link at 1575 MHz with C/A code only to resolve a measured range to the satellite. A theoretical range is computed from the satellite ephemeris transmitted in the data message and the user's coordinates. Results of user offset from GPS time are obtained by differencing the measured and theoretical ranges and applying calibration corrections. Results of the first field test evaluation of the receiver are presented

Indianola

[Verse 1] Chief Bug-a-Boo was a Redman who, Heard the call of war (aw aw aw,) Swift to the tent of his love he went, Sighing for his little Indianola, “Come be the bride of a chief” he cried, “Keep me wait no more (aw aw aw,) Come and help me make my war paint fit, I do my heap big bit.” [Chorus 1] “Me hear cannon roar, Me help Yank win war, Me much like to kill, Scalp old Kaiser Bill; Me go to fight in France, Me do a big war dance, Me love a maiden so, Wed Chief ‘fore he go. Indianola’s lover grunted twice, Huh! Huh! Indianola think her Chief much nice, Huh! Huh! Indianola ask her dad’s advice Chief keep pleading: Me hear the great big cannon roar, Me want to help Yank man win war, Me like to fight and to heap much kill, Got to go and tomahawk Kaiser Bill; Me go along to fight in France Me once again do big war dance, Me love the Indianola maiden so, Come and marry Bug-a-Boo ‘fore he go. [Verse 2] Then answered she to the Redman’s plea, “I will be your squaw (aw aw aw,) Chief Bug-a-Boo I will go with you, Riding o’er the plain to Redman’s wigwam, There will I sit and I’ll knit and knit, For my warrior bold And when you are whooping far away, To me you’ll seem to say.” [Chorus 2] “Me hear cannon roar, Me help Yank win war, Me much like to kill, Scalp old Kaiser Bill; Me go to fight in France, Me do a big war dance, Me love a maiden so, Wed Chief ‘fore he go. Indianola’s heart begins to yearn, Huh! Huh! Indianola’s cheeks begin to burn, Huh! Huh! Indianola sighs for his return And his pleading: Me hear the great big cannon roar, Me want to help Yank man win war, Me like to fight and to heap much kill, Got to go and tomahawk Kaiser Bill; Me go along to fight in France Me once again do big war dance, Me love the Indianola maiden so, Come and marry Bug-a-Boo ‘fore he go

Bacterial microcompartment-directed polyphosphate kinase promotes stable polyphosphate accumulation in E. coli

Processes for the biological removal of phosphate from wastewater rely on temporary manipula-tion of bacterial polyphosphate levels by phased environmental stimuli. In E. coli polyphosphate levels are controlled via the polyphosphate-synthesizing enzyme polyphosphate kinase (PPK1) and exopolyphosphatases (PPX and GPPA), and are temporarily enhanced by PPK1 overexpression and reduced by PPX overexpression. We hypothesized that partitioning PPK1 from cytoplasmic exopoly phosphatases would increase and stabilize E. coli polyphosphate levels. Partitioning was achieved by co-expression of E. coli PPK1 fused with a microcompartment-targeting sequence and an artificial operon of Citrobacter freundii bacterial microcompartment genes. Encapsulation of targeted PPK1 resulted in persistent phosphate uptake and stably increased cellular polyphos-phate levels throughout cell growth and into the stationary phase, while PPK1 overexpression alone produced temporary polyphosphate increase and phosphate uptake. Targeted PPK1 increased polyphosphate in microcompartments eight-fold compared with non-targeted PPK1. Co-expression of PPX polyphosphatase with targeted PPK1 had little effect on elevated cellular polyphosphate levels because microcompartments retained polyphosphate. Co-expression of PPX with non-targeted PPK1 reduced cellular polyphosphate levels. Thus, subcellular compartmentali-zation of a polymerizing enzyme sequesters metabolic products from competing catabolism by preventing catabolic enzyme access. Specific application of this process to polyphosphate is of potential application for biological phosphate removal
