Apparatus for assembling space structure
An apparatus for producing a structure in outer space from rolls of prepunched ribbon or sheet material that are transported from the earth to the apparatus located in outer space is described. The apparatus spins the space structure similar to a spider spinning a web utilizing the prepunched ribbon material. The prepunched ribbon material is fed through the apparatus and is shaped into a predetermined channel-shaped configuration. Trusses are punched out of the ribbon and are bent downwardly and attached to a track which normally is a previously laid sheet of material. The size of the overall space structure may be increased by merely attaching an additional roll of sheet material to the apparatus
Testing the Standard Model with Radiative Penguin Decays at BaBar
The author discusses two recent results in b {yields} s{gamma} decays from BABAR. The first is a measurement of the branching fraction and photon energy spectrum in the B meson frame of the decay B {yields} X{sub s{gamma}}. The second result probes the photon polarization via time-dependent CP violation in neutral B decays to K*{sup 0}{gamma}
The Use of Knowledge Management Methodologies to Improve the Practice of Supply Chain Management: The Case of the Bullwhip Effect
Supply Chain Management is a critically important approach toward producing and delivering goods and services in a cost-effective, timely manner. However, many SCM systems in practice exhibit the bullwhip effect, a tendency towards increasing variability in demand as this type of information migrates downwards in the producing supply chain. We argue that one can reduce the size of the bullwhip effect through the judicious use of knowledge management technologies. We have advanced our arguments through several propositions, and we have derived a set of testable hypotheses from two of these propositions in order to demonstrate how one would go about verifying these arguments. We have identified two different general research methodologies in order to provide a multiple methodological approach to gaining greater confidence in the propositions. It now remains to carry out this plan of research
Rapid Communication: The Very-Long-Chain Acyl-CoA Dehydrogenase Gene Maps to Pig Chromosome 12
Source and Description of Primers. Primers for the very-long-chain acyl-CoA dehydrogenase (ACADVL) gene were designed from a bovine cDNA sequence (GenBank accession No. U30817) aligned with the human ACADVL gene (GenBank accession No. L46590). The forward primer was 5¢-TTT GGG GAG AAA ATT CAC AAC-3¢ and the reverse primer was 5¢-GCG GCC TCT ATC TGG AAG T-3¢. The amplification product was expected to span from exon 11 to exon 12 of the ACADVL gene. Exonic parts (103 bp) of the pig sequence were 91% identical at the nucleotide level with the human ACADVL sequence. The pig sequence produced here has been submitted to GenBank (accession no. AF022255)
Rapid Communication: A HincII Polymorphism in the Porcine Calpain, Large Polypeptide L3 (CAPN3) Gene
Source and Description of Primers. Primers were designed from a published, partial porcine cDNA sequence (Genbank accession no. U05678) in positions corresponding to exons 11 and 13 of the human CAPN3 gene (Genbank accession no. X85030). Sequences were obtained from the ends of the PCR fragment and compared with the porcine cDNA sequence showing 98.1% identity in a 108-bp overlap at the exon 11 end and 99.2% identity in a 124-bp overlap at the exon 13 end. Sequences produced in this study have been submitted to Genbank (accession no. AF025660-AF025661)
Quantitative Measurement of PIT1, GH, and PRL mRNA and Circulating Hormone Levels in Pig Families Segregating PIT1 Genotypes
PIT1 is a member of the POU-domain family gene and is a positive regulator for growth hormone (GH), prolactin (PRL), and thyrotroph-stimulating hormone β(TSHB) in several mammalian species. Previous studies in pigs have shown an association of PIT1 polymorphisms with growth and carcass traits in which the primarily Chinese alleles were associated with heavier birth weight and greater backfat. To further investigate the role of PIT1 in controlling pig growth traits, Chinese Meishan (MS) pigs segregating PIT1 polymorphisms were used to study the differences of GH and PRL at both mRNA and circulating hormone levels. A total of 60 animals from nine litters was used to collect both pituitary and blood samples at day 1, 15, and 30 after birth. A novel procedure that involves standard curve quantification was used to quantify mRNA amount for GH, PRL, PIT1-α, and PIT1-β. Conventional hormone assays were done to measure the circulating amount of GH and PRL from the blood. Statistical analyses of PIT1 genotypes, sex, and days on either mRNA (PIT1 alternative transcripts, GH, and PRL) or circulating hormone (GH and PRL) were done by using the leastsquares procedure. This study investigates GH and PRL at both mRNA and circulating hormone levels in MS pigs segregating PIT1 polymorphisms. Results from this study will provide useful information on the role of PIT1 in controlling pig growth traits
