ISSN: 1540-5915Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: EconomicsNotes: In this paper, Virtual Cellular Manufacturing (VCM), an alternative approach to implementing cellular manufacturing, is investigated. VCM combines the setup efficiency typically obtained by Group Technology (GT) cellular manufacturing (CM) systems with the routing flexibility of a job shop. Unlike traditional CM systems in which the shop is physically designed as a series of cells, family-based scheduling criteria are used to form logical cells within a shop using a process layout. The result is the formation of temporary, virtual cells as opposed to the more traditional, permanent, physical cells present in GT systems. Virtual cells allow the shop to be more responsive to changes in demand and workload patterns. Production using VCM is compared to production using traditional cellular and job shop approaches. Results indicate that VCM yields significantly better flow time and due date performance over a wide range of common operating conditions, as well as being more robust to demand variability.Type of Medium: Electronic ResourceURL: -

Comparison of room-temperature spectra with those for standard Fe/NaY gave evidence for interaction between Pt and Fe. This result is discussed with respect to the phenomenon of chemical anchoring of Pt in zeolites.Type of Medium: Electronic ResourceURL: -

Published 1983Staff ViewISSN: 1432-0983Keywords: Saccharomyces cerevisiae ; Isoenzymes ; InductionSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Summary Tetrad analysis indicates that α-isopropylmalate synthase activity of yeast is determined by two separate genes, designated LEU4 and LEU5. LEU4 is identified as a structural gene. LEU5 either encodes another α-isopropylmalate synthase activity by itself or provides some function needed for the expression of a second structural gene. The properties of mutants affecting the biosynthesis of leucine and its regulation suggest that the expression of LEU1 and LEU2 (structural genes encoding isopropylmalate isomerase and β-isopropylmalate dehydrogenase, respectively) is controlled by a complex of a-isopropylmalate and a regulatory element (the LEU3 gene product). Similarities and differences between yeast and Neurospora crassa with respect to leucine biosynthesis are discussed.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-904XKeywords: hydrogels ; site-specific ; drug delivery ; chitosan ; poly-(ethylene oxide)Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract Purpose. The purpose of this study was to develop novel drug delivery systems with pH-sensitive swelling and drug release properties for localized antibiotic delivery in the stomach. Methods. The drug delivery systems were synthesized by crosslinking chitosan and poly(ethylene oxide) (PEO) in a blend to form semi-interpenetrating polymer network (semi-IPN). Scanning electron microscopy was used to compare the surface and bulk morphology of the freeze-dried and air-dried chitosan-PEO semi-IPN. The hydrogels were allowed to swell and release the antibiotics—amoxicillin and metronidazole—in enzyme-free simulated gastric fluid (SGF, pH 1.2) and simulated intestinal fluid (SIF, pH 7.2) at 37°C. Results. Freeze-dried chitosan-PEO semi-IPN with a porous matrix had swollen extensively as compared to the air-dried hydrogel. The swelling ratio of freeze-dried and air-dried chitosan-PEO semi-IPN after 1 h in SGF was 16.1 and 2.30, respectively. More than 65% of the entrapped amoxicillin and 59% of metronidazole were released from the freeze-dried chitosan-PEO semi-IPN after 2 h in SGF. Conclusions. The results of this study suggest that freeze-dried chitosan-PEO semi-IPN could be useful for localized delivery of antibiotics in the acidic environment of the gastric fluid.Type of Medium: Electronic ResourceURL: -

ISSN: 1435-1528Keywords: Key words Entangled polymers ; constitutive equation ; incomplete retraction ; partial extensibility ; time-strain separabilitySource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyPhysicsNotes: Abstract Beginning with a formal statement of the conservation of probability, we derive a new differential constitutive equation for entangled polymers under flow. The constitutive equation is termed the Partial Strand Extension (PSE) equation because it accounts for partial extension of polymer strands in flow. Partial extensibility is included in the equation by considering the effect of a step strain with amplitude E on the primitive chain contour length. Specifically, by a simple scaling argument we show that the mean primitive chain contour length after retraction is L=L 0 E 1/2, not the equilibrium length L 0 as previously thought. The equilibrium contour length is infact recovered only after a characteristic stretch relaxation time λ s that is bounded by the reptation time and longest Rouse relaxation time for the primitive chain. The PSE model predictions of polymer rheology in various shear and extensional flows are found to be in good to excellent agreement with experimental results from several groups.Type of Medium: Electronic ResourceURL:
