Opis:
Huang and Hsu (2008) investigated the inventory system as a cost minimization problem, with the objective to determine the retailer’s optimal inventory policy under the supply chain conditions. Then, Chung (2008) presented the comments to this problem, with the aim to overcome the shortcomings and present complete proofs for the results, relative to Huang and Hsu (2008). However, the proof, proposed by Chung is cumbersome, and can be followed with difficulty. The main purpose of this paper is to develop another proof, much more easy to comprehend.

Opis:
A numerical analysis of loss has been carried out to explore the loss mechanism of leading edge tubercles in a high speed compressor cascade. Taking the lead from flippers of the humpback whale, tubercles are passive structures of a blade for flow control. Evaluation of the overall performance in terms of entropy increase shows that the loss reduction is achieved both at high negative and high positive incidence angles, while a rise in the loss is obtained near the design point. And a smaller wave number as well as a smaller amplitude results in lower additional losses at the design point. Spanwise and streamwise distributions of pitchwise-averaged entropy increase combined with flow details have been presented to survey the loss development and, subsequently, to interpret the loss mechanism. The tubercle geometry results in the deflection flow and the consequent spanwise pressure gradient. This pressure gradient induces formation of counter-rotating streamwise vortices, transports away the low-momentum fluid near wall from crests towards troughs and leads to local high loss regions behind troughs as well as loss reduction behind the crests in comparison to the baseline. The interaction between these vortices and flow separation by momentum transfer leads to separation delay and the consequent loss reduction at the outlet.

Opis:
The effect of cone size on interfacial bonding strength of bimetallic composite pipe manufactured by drawing approach is studied on base of the plane strain assumption and ideal elastic-plastic model, a simple expression for the effect of cone size on the bonding strength of bimetallic composite pipes is proposed. The agreement of the predicted results with the experimental results shows the reliability.

Opis:
Pinellia ternata is one of the most important herbs in traditional Chinese medicine. Recently, its yield is hard to meet the market demand, therefore the system of in vitro micro-tubers was developed for its propagation and endogenous GA was revealed probably function negatively during micro-tubers induction. However, the mechanism is still unknown. In this study, 70 mg/L chlormequat chloride (CCC) was successfully used to inhibit the endogenous GA content and promote the micro-tubers induction. Subsequently, suppression subtractive hybridization (SSH) was performed to identify GA-related genes associated with in vitro micro-tubers formation in P. ternata. The cDNAs of micro-tubers induced with and without CCC were used as the “tester”, and “driver”, respectively. SSH library sequencing yielded 300 expressed sequence tags (ESTs). Finally, 226 ESTs were retained after screening, 84 of which had no significant homology to any of previously identified genes and 39 of the remaining 142 ESTs represented singletons. Real-time quantitative RT-PCR analysis of the expression patterns showed that all 5 transcripts showed signal alteration during the process of in vitro micro-tubers formation. The sequences appeared to be highly homologous with 60S ribosomal protein, 26S ribosomal RNA gene, zinc transporter protein, 12kD storage protein and malate dehydrogenase, respectively. These results would facilitate the functional characterization of the GA-related genes associated with in vitro micro-tubers development and subsequent in vitro manipulation.
