Production Estimating for Draglines

Dragline productin estimates, as derived from published tables, are compared to actual field production. Several equipment texts present dragline production estimating tables. The base data source for most of these tables are studies performed by the Power Crane and Shovel Association, PCSA. Only a small variance existed between the actual and estimated production.     

Materials for endosseous dental implants

Melatonin production by isolated pineal glands from guinea pigs was examined under conditions that affect membrane potential or the firing of action potential-like spikes. In glands from superior cervical ganglionectomized animals, depolarization resulting from increasing extracellular potassium concentration to 100 mM did not initiate melatonin production, and it delayed the response to the beta-adrenoceptor agonist orciprenaline. In glands from intact animals melatonin production was initiated by exposure to 100 mM potassium with a time-course similar to the response to orciprenaline. A proportion of this response was propanol resistant, suggesting that the normal control of melatonin production may involve a neurotransmitter in addition to norepinephrine. Exposure to verapamil or nifedipine, or removal of extracellular calcium, previously shown to eliminate action potential-like spikes, did not substantially affect the increase in melatonin production induced by orciprenaline. Phenylephrine, which stimulates spiking, produced only a slight increase in melatonin production. It is concluded that the depolarization and the spiking are not closely related to the stimulation of melatonin production, but may relate principally to the secretion of a substance other than melatonin.     

基于成本的线材生产计划系统优化设计

由于生产计划的编制涉及机组、库存、周期、品种、生产节点等多方面的因素,计划合理与否的评判标准长期以来一直是各方争论的焦点。将成本概念引入到生产计划中,以成本作为评定标准来衡量计划的合理性,从而使计划评判更加科学、规范和合理。基于成本的线材生产计划系统是通过建立实质意义上的预PONO(制造命令号)处理、预合同计划处理、制程优化模型、材料优化模型以及在制品库存的动态预报等功能,来实现最终的成本评估,使电炉连铸、线材的产能得到更为合理的发挥,在制品库存得到更有效的控制,原料的生产周期以及无委托量等方面有所下降,最终达到降低成本、提高效益的目的。

多策略代谢工程大肠杆菌高效生产辅酶Q10

Escherichia coli BW25113 was metabolically engineered for CoQ10 production by replacing ispB with ddsA from Gluconobacter suboxydans. Effects of precursor balance and reduced nicotinamide-adenine dinucleotide phosphate (NADPH) availability on CoQ10 production in E. Coli were investigated. The knockout of pykFA along with pck overexpression could maintain a balance between glyceraldehyde 3-phosphate and pyruvate, increasingCoQ10 production. Replacement of native NAD-dependent gapA with NADP-dependent gapC from Clostridium acetobutylicum, together with the overexpression of gapC, could increase NADPH availability and then enhanced CoQ10 production. Three effects, overcxpressions of various genes in CoQ biosynthesis and central metabolism,different vectors and culture conditions on CoQ10 production in E. Coli, were all investigated. The investigation of different vectors indicated that low copy number vector may be more beneficial for CoQ10 production in E. Coli.The recombinant E. Coli (AispB::ddsA, ApykFA and ΔgapA::gapC), harboring the two plasmids encoding pck, dxs,idi and ubiCA genes under the control of PT5 on pQE30, ispA, ddsA from Gluconobacter suboxydans and gapC from Clostridium acetobutylicum under the control of PBAD on pBAD33, could produce CoQ10 up to 3.24 mg.g-1 dry cell mass simply by changing medium from M9YG to SOB with phosphate salt and initial culture pH from 7.0 to 5.5. The yield is unprecedented and 1.33 times of the highest production so far in E. Coli.     

Decision Support System for Manufactured Housing Facility Layout

Productivity improvement of manufactured housing (MH) production systems has been a great concern to manufacturers and production managers. Studies show that a typical manufactured housing plant fails to produce at desired capacity and production rate because of several shortcomings. The evaluation of the production system efficiency in the factory is essential for meeting the growing demand of customers with respect to design and size of the housing product. It is imperative to explore alternative layout designs that would be more efficient and productive. A decision support system (DSS) is proposed to assist the user in selecting an efficient layout design matching specified requirements and business constraints. The DSS framework covers interrelated factors of: (1) the market demand; (2) MH organization; (3) MH production process; and (4) MH production planning and facility design. Existing MH factories can utilize simulation and optimization components of the DSS in streamlining their activities and locating then solving potential bottlenecks. Additionally, the DSS can be used in selecting optimal production system layout for new plant design.

Computer-based neuroanatomy laboratory for medical students

Bone is one of the most common sites of metastasis in melanoma and breast cancer cells. Human melanoma (A375M) and human breast cancer (MDA-MB-231) cells form osteolytic bone metastasis in vivo when these tumor cells are injected into the left ventricles of BALB/c nude mice. These tumor cells promote bone resorption in the in vitro neonatal murine calvaria organ culture system by indirectly stimulating the production of a bone resorption-inducing factor (or factors) from human osteoblast-like cells. This secreted factor was identified as interleukin-11 (IL-11). Although many cytokines and hormones were associated with IL-11 production from osteoblasts, transforming growth factor-beta (TGF-beta) was found to be involved in the promotion of IL-11 production from osteoblasts, because the addition of a neutralizing anti-TGF-beta antibody decreased the production of IL-11. However, these tumor cells did not produce TGF-beta by themselves. We found that they enhanced IL-11 production by activating latent TGF-beta produced from osteoblast-like cells. Our results indicate that metastatic tumor cells induce osteolysis by activating TGF-beta, which leads IL-11 production from osteoblasts to promote bone resorption.
