Application of product data management within the product development process
No full textManufacturing companies need to be able to respond to customer demand quickly
and accurately. This requires the capability to manage product data effectively.
Product Data Management (PDM) systems have been identified as a solution to
deliver this capability by providing the right information to the right people at the
right time and in the right format.
The foundation of this research is that the concept of PDM is relevant and important
within the product development process. This research focuses upon how the PDM
concept is applied in practice to define and configure products and how it can be
integrated with other major information systems to enable an enterprise wide
information system. To enable the research aim, an extensive review of literature
was undertaken to investigate the effectiveness of PDM in enhancing the product
definition process and in creating an interface between different business functional
areas.
A survey ofPDM system usage was undertaken aimed at identifying the current level
of PDM usage within manufacturing enterprises in the UK. This was followed up by
three industrial case studies to provide some degrees of validation of the results
obtained. A need for effective one time order capture was identified from the three
case studies which led to the development of a model specification for a late product
configuration tool. A prototype system was produced to validate the design
specification and was successfully demonstrated to a collaborating company. During
the submission of this thesis, the collaborating company and the university are
working on funding a project to pursue with its implementation.
The work undertaken has firmly established the relevance ofPDM within the product
development process and the importance of effective interfaces between PDM and
other manufacturing information systems. The research will be of interest to small
and medium sized manufacturing companies searching solutions for improving the
management of their product data to enhance product definition and configuration

No full textRNA-sequencing data of Balb/c involuting mammary gland treated with anti-Ly6G antibody and estrogen
No full textFemale Balb/c mice were oxvariectomed at lactation day 2, pups forced weaned at lactation day 12 to initiate mammary involution. At 24 hours post-weaning, mice were treated with anti-Ly6G antibodies or isotype control. At 48 hours post-weaning, mice were treated with 20µg/kg of body weight estrogen or vehicle control. Mice sacrificed after 24 hours estrogen treatment and mammary sample collected and frozen. Mammary samples were extracted for total RNA using Trizol reagen and then treated with Dnase1 before sending for library preparation and sequencing by A*STAR GIS using illumina HiSeq4000

The date of the Leng-chia shih-tzu chi
No full textAmong the many manuscripts relating to Ch’an Buddhism included in the Tun-huang finds of the early years of this century, the Leng-chia shih-tzu chi has always been regarded by scholars as a discovery of unusual importance, since it presents an unrivalled picture of the early development of this type of Buddhism from the long-obscured viewpoint of the so-called Northern school of Ch’an. The text has been rendered into English lately by J. C. Cleary, but only in a translation intended for a non-scholarly audience. Fortunately, however, the new French-language translation and study by Bernard Faure is everything a scholar could wish for, a worthy product of many years of research, including several spent at the feet of Yanagida Seizan, Japan's outstanding authority on the early historiography of Ch’an. Faure's work, not surprisingly, shows a complete grasp of the complex issues of intellectual history raised by his text, and also provides copious commentary on its author, Ching-chüeh (683–c. 750), and his background.</jats:p
The origins of carbonatites and related rocks from the Grønnedal-Íka Nepheline Syenite complex, South Greenland: C-O-Sr isotope evidence
No full textThe Grønnedal-Íka ring complex (1299 ± 17 Ma) in the Gardar province, South Greenland is composed of a range of layered nepheline syenites which were intruded at a late stage by xenolithic syenite and a plug of carbonatite. The complex was subsequently intruded by a variety of basic dykes, including olivine dolentes, kersantites, vogesites, spessartites, camptonites and an alnöite, and then extensively faulted. The nepheline syenite magmas, produced by fractional crystallisation of basic magmas, show a range in δ13C (-3.86 to -7.57‰) and δ18O (8.27 to 15.12‰), distinctly different to the carbonatites which form a tight group with average δ13C= -4.31 ± 0.22 ‰, (1 s.d.) and average δ18O= 7.18 ± 0.41‰(1 s.d.). Initial 87Sr/86Sr isotope ratios (typically 0.703) suggest the syenites and carbonatites have not assimilated crustal rocks, and therefore the C and O isotope variation within each group is a result of isotopic evolution during fractional crystallisation. A suite of lamprophyre dykes (δ13C -3.86 to -7.86‰ and δ18O 9.12 to 10.81‰) form a coherent group whose stable isotope compositions overlap part of the syenite field, and again are distinctly different from the carbonatites. A single alnöite has δ13C = -3.32‰ and δ18C= 12.34‰. C and O isotope ratios are consistent with origins of syenitic and lamprophyric magmas from a similar source. Despite geochemical evidence which suggests a genetic link between nepheline syenites and carbonatites, C and O isotopic evidence shows that they are not related directly by liquid immiscibility. Comparisons are made between similar rock types from Grønnedal-Íka and from the Gardar Igaliko Dyke Swarm. The possible role of F in controlling δ13C and δ18O during crystallisation of calcite from carbonatite magmas is discussed
The Antigastric Cancer Activity of San Leng Powder Extract Induces Apoptosis in Balb/C Bearing-SGC-7901 Mice
No full textSan Leng powder extract has been used as medicinal compound for the prevention and treatment of cancers. The antitumor activity of SLPE was determined by treating BALB/C mice harboring a human gastric cancer xenograft with SPLE for 17 days. Mice were also treated with fluorouracil (5-Fu, 25 mg/kg) or a combination of SLPE and 5-Fu. Our results indicate that the inhibition of tumor growth by SLPE might be due to a block in the cell cycle and the induction of apoptosis. These results suggest that SLPE might be useful in the treatment of gastric cancer.</jats:p
