Influences of Thermal Martensites and Grain Orientations on Strain-induced Martensites in High Manganese TRIP/TWIP Steels

Strain-induced martensites in high manganese TRIP/TWIP steels were investigated in the presence of thermal martensites and under the influence of austenitic grain orientation by X-ray diffraction(XRD),scanning electron microscopy(SEM) and electron backscattered diffraction(EBSD).Before deformation,the morphology of α’-M depended mainly on the number of variants and growing period.Regardless of martensite morphologies and deformation,the Kurdjumov-Sachs(K-S) orientation relationships always maintained.The 6 α-M variants formed from a plate of ε-M were of 3 pairs of twins with a common axis <110>_(α’) parallel to the normal of {111}_γ habit plane to minimize transformation strain.When α’-M could be formed only by deformation,it nucleated at the intersection of ε-M variants and grew mainly in thick ε-M plates.Thick ε plates promoted significantly the α’-M and weakened the influence of grain orientations.During tension,the transformation in <100>-oriented grains was observed to be slower than that in <111>-oriented grains.Deformation twins promoted ε-M formation slightly and had no apparent effect on α’-M.Deformation increased the number of ε-M variants,but reduced that of α’-M variants.
Implication of Geochemical Simulation for CO_2 Storage Using Data of York Reservoir

In this paper, we build up a three-dimensional model for CO2 storage in the deep reservoir. And this paper gives the mathematical formalism of combined geochemical and multi-phase flow. The results give us the information about geochemical changing caused by CO_2 injection into aqueous, the dissolution or precipitation of reservoir minerals caused by aqueous components change, the change of water density, also the differences between this model and the simulation model without considering geochemical. The basic data for simulation is from York Reservoir.
Synthesis of Wax Esters by Lipase-catalyzed Esterification with Immobilized Lipase from Candida sp. 99-125

Wax esters were synthesized in a solvent free system catalyzed by immobilized lipase from Candida sp. 99-125, with oleic acid and cetyl alcohol. The effects of substrate molar ratio, lipase dosage and water removal were investigated in a 50 ml flask incubated in a thermostatic cultivation cabinet. The optimized conditions were: temperature 40 ℃, shaking at 170 r·min-1, acid/alcohol molar ratio 1:0.9, lipase dosage in 10% (by mass) of oleic acid, and open reaction for water removal. As a result, the conversion rate reached 98% for reaction of 8 h. The volume of reactor was scaled up to 1 L three-neck flask. The optimized parameters were: 200 r·min-1 agitation speed, 2.5% (by mass) lipase dosage, others were the same as the parameters described above. The conversion rate reached 95% for reaction of 24 h. The lipase retained 46% conversion rate after reuse for 6, 7 batches. The products were purified by removing remained cetyl alcohol and fatty acids with ethanol and saturated sodium carbonate so-lution, respectively. The purity of the wax ester, cetyl oleate, was 96%. The physical and chemical properties of cetyl oleate were tested and compared with those of jojoba oil. The results show that the product cetyl oleate has great potential to use as the substitute of natural jojoba oil.
Kinetics of Formic Acid-autocatalyzed Preparation of Performic Acid in Aqueous Phase

Performic acid (PFA) is an oxidant used in chemical processing, synthesis and bleaching. The macro kinetic models of synthesis, hydrolysis and decomposition of PFA were investigated via formic acid-autocatalyzed reaction. It was found that the intrinsic activation energies of PFA synthesis and hydrolysis were 75.2 kJ·mol-1 and 40.4 kJ·mol-1 respectively. The observed activation energy of PFA decomposition was 95.4 kJ·mol-1. The experi-mental results indicated that the decomposition of PFA was liable to occur even at the ambient temperature. Both the spontaneous decomposition and the radical-introduced decomposition contributed to the decomposition of PFA.
Modeling and Multi-objective Optimization of Refinery Hydrogen Network

The demand of hydrogen in oil refinery is increasing as market forces and environmental legislation, so hydrogen network management is becoming increasingly important in refineries. Most studies focused on single-objective optimization problem for the hydrogen network, but few account for the multi-objective optimization problem. This paper presents a novel approach for modeling and multi-objective optimization for hydrogen network in refineries. An improved multi-objective optimization model is proposed based on the concept of superstructure. The optimization includes minimization of operating cost and minimization of investment cost of equipment. The proposed methodology for the multi-objective optimization of hydrogen network takes into account flow rate constraints, pressure constraints, purity constraints, impurity constraints, payback period, etc. The method considers all the feasible connections and subjects this to mixed-integer nonlinear programming (MINLP). A deterministic optimization method is applied to solve this multi-objective optimization problem. Finally, a real case study is intro-duced to illustrate the applicability of the approach.
Effects of Photoperiod on Alternative Respiration Pathway in Nectarine Flower Buds During Dormancy Induction

Characteristics of dormancy induction and alternative respiration pathway (also known as cyanide-resistant respiration) of nectarine flower buds in different photoperiods were studied to determine the function of photoperiod and alternative respiration pathway in dormancy induction. Oxygen-electrode system and respiratory inhibitors were used to measure total respiratory rates and rates of alternative respiration pathway. The results showed that total respiration rate (V_t) in flower buds showed to be double hump-shaped curves. Short day raised, brought the first-hump of V_t forward and delayed the second-hump, while long day delayed the whole curve. The capacity (V_(alt)) and activity (ρV_(alt)) of SD and LD changed synchronously and both showed to be double hump-shaped curves. Short day made the first climax of V_(alt) and ρV_(alt) existed much earlier, while long day increased their rates significantly. The length of day had little effects on the later period climax. Long day also increased the contributions of alternative respiration pathway in total respiration rate (ρV_(alt)/V_t). The changes in alternative respiration pathway were correlated with the induction of dormancy and adjusted by photoperiod. Short day promoted dormancy induction of nectarine trees, while long day delayed it.
Effects of the Spatial Coupling of Water and Fertilizer on the Chlorophyll Fluorescence Parameters of Winter Wheat Leaves

Wheat is an important agricultural crop in the Loess region of China, where there is drought stress and low availability of soil nitrogen and phosphorus. Using a pulse modulation fluorometer, we studied the effects of water, nitrogen, and phosphorus on the kinetic parameters of chlorophyll fluorescence in winter wheat. The wheat was grown in layered columns of Eum-Orthic Anthrosol (Cinnamon soil), with the water content and nutrient composition of each layer controlled. The results showed that the kinetic parameters of chlorophyll fluorescence were sensitive to water stress. The basic fluorescence (F_0) of leaves was higher in the dry treatment (0-30 cm layer at 40-45% of field capacity, 30-90 cm at 75-80% of field capacity) compared to the wet treatment (entire soil column at 75-80% of field capacity). The maximal fluorescence (F_m), the variable fluorescence (F_v), the photochemical efficiency (F_v/F_m) and potential activites (F_v/F_0) of photosystem 2 (PS2) were significantly lower in the dry treatment. Although drought stress impaired PS2 function, this effect was significantly ameliorated by applying P or NP fertilizer, but not N alone. P application increased F_v/F_m, both in well-watered and water stressed plants, especially when fertilizer was applied throughout the column or within the top 30 cm of soil. A combined fertilizer improved photosynthesis in well watered plants, with F_m and F_v/F_m being the highest when fertilizer was applied throughout the columns. For drought stressed, plants F_v/F_m was significantly greater when combined fertilizer was added within the top 30 cm of soil. We concluded that, when growing winter wheat in both arid and semi-arid parts of the Loess region of China, it is important to guarantee the nutrient supply in the top 30 cm of the soil.
The Responses of Morphological Trait, Leaf Ultrastructure, Photosynthetic and Biochemical Performance of Tomato to Differential Light Availabilities

The whole-plant morphology, leaf ultrastructure, photosynthesis as well as enzyme activities of two tomato cultivars (Meifen-2 and Hongsheng) to differential light availabilities (450-500 μmol m~(-2) s~(-1), 75-100 μmol m~(-2) s~(-1)) were examined in controlled environment. The results showed that the plant biomass and root/shoot ratio decreased and the specific leaf area increased significantly under the low light condition. There was a significant increase in malondialdehyde (MDA) concentration, superoxide dismutase (SOD) and peroxidase (POD) activities and decrease in soluble sugar and protein contents in LL-grown plants. For both cultivars, downregulation of photosynthesis and electron transport components were observed in LL-grown plants, the inhibition of the photosynthesis under the LL condition could be partially explained by the decrease of stomata density and by the changes of chloroplast.
Fine Mapping and Cloning of the Grain Number Per-Panicle Gene (Gnp4) on Chromosome 4 in Rice (Oryza sativa L.)

Grain number per-panicle is one of the most important components for rice yield. Spikelets on the primary and secondary branches determine the grain number per-panicle in rice. In this study, we identified a natural mutant, gnp4, lack of lateral spikelet on the secondary branches in the field condition. In addition, the Gnp4 and Lax1-1 double mutant showed dramatically reduced secondary branches and spikelets in panicle at reproductive stage, and tillers at vegetative stage. By map-based cloning approach, and using four F_2 segregating populations, the Gnp4 gene was finally mapped to a 10.7-kb region on the long arm of chromosome 4 in rice. In this region, only one gene was predicted, and genomic DNA sequencing of the 10.7-kb region showed no nucleotide differences between the mutant and wild type. Interestingly, we found that the methylation level of several cytosines in the promoter CpG islands region of the predicted gene in gnp4 were different from the wild type. Thus, we propose that the DNA methylation changes at these sites may induce to decrease expression level of Gnp4, consequently, resulting in phenotypic variation.

手指全形再造的重要意义

手不仅是劳动的工具，还是人的仪表的重要组成部分。手指缺损不仅给人的生活与工作造成不便，而且还影响到人的形象和社交活动。因而，在临床上，对手指缺失进行修复与再造，就显得相当重要~([1])。数十年来，人们尝试了多种手指再造的方法。在这些方法中，从再造手指的功能与外形两方面综合来看，足趾移植再造手指是目前最好的方法之一~([2])。随着显微外科的深入发展，足趾移植再造手指的技术无论国内国外都已经较为普及。迄今，对手指缺损取足趾移植再造，显然不再有争议，但足趾移植再造手指这一术式并不完美：一是再造的手指细短，外形仍像个足趾，外观、指甲大小、指节长度、关节位置以及手指直径与总长度等方面与原先手指还有较大的差距；二是手术对足供区的破坏太大，特别是当多手指缺损、要切取3个以上的足趾再造“手”时，足的功能受到严重影响，因此，很多学者都认为，即使对于全手指缺失的病例，在施行足趾移植再造手指时，移植的足趾的数量最好也不要超过3个~([3])。
Cretaceous Sandbody Characters at Shallow-Water Lake Delta Front and the Sedimentary Dynamic Process Analysis in Songliao Basin, China

Based on the abundant information from drilling, cores, and logging, the influence of topography, size of rivers and lakes, climate changes and the lake level's fluctuation on the sandbodies at shallow-water delta front are systematically summarized and the sedimentary dynamic processes are analyzed. The interwell communication among the sandbodies and their planar distribution revealed from the hydrodynamic features of the development wells are integrated during the analysis. The fundamental requirements for the development of the shallow-water delta included flat topography and uniform subsiding rate. The delta plain was connected smoothly with the wide delta front and predelta, without the three-fold structure of topset, foreset, and bottomset as defined in the Gilbert Delta Model. Because of the weak fluvial effect and the lake energy is strong, the small and scattered shallow-water delta is destroyed by the scouring-backwashing, coastal current, and lake wave, resulting in the coastal sheet deposition. As the fluvial effect became stronger and the lake energy became weaker, the shape of the shallow-water deltas transferred from sheets to lumps and then branches.
China's First Independent Cobalt Deposit and its Metallogenic Mechanism: Evidence from Fluid Inclusions and Isotopic Geochemistry

The Tuolugou cobalt deposit is the first independent large-scale Co- and Au-bearing deposit discovered in northwestern China. It is located in the eastern Kunlun orogenic belt in Qinghai Province, and occurs conformably in low-grade metamorphic volcano-sedimentary rock series with well-developed Na-rich hydrothermal sedimentary rocks and typical hydrothermal sedimentary ore fabrics. Fluid inclusions and isotopic geochemistry studies suggest that cobalt mineralizing fluid is dominated by NaCl-H_2O system, accompanied by NaCl-CO_2-H_2O-N_2 system responsible for gold mineralization. Massive, banded and disseminated pyrite ores have similar compositions of He and Ar isotopes from the mineralizing fluid, with ~3He/~4He range between 0.10 to 0.31Ra (averaging 0.21Ra), and ~(40)Ar/~(36)Ar between 302 and 569 (averaging 373), which reflects that Co mineralizing fluids derived dominantly from meteoric water deeply circulating. δ~(34)S values of pyrite approaches to zero (δ~(34)S ranging from -4.5‰ to +1.5‰, centering around -1.8‰ to -0.2‰), reflecting its deep source. Ore lead is characterized by distinctly high radiogenesis, with ~(206)Pb/~(204)Pb>19.279, ~(207)Pb/~(204)Pb>15.691 and ~(208)Pb/~(204)Pb>39.627, and its values show an increase trend from country rocks, regional Paleozoic volcanic rocks to ores. This may have suggested that high radiogentic ore Pb derived mainly from country rocks by leaching meteoric water-dominated hydrothermal fluid during its circulation at depth. Cobalt occurs mainly in sulfide phase (such as pyrite), but cobalt enrichment, and presence and increasing contents of Co-bearing minerals have a positive correlation with metamorphic degree. The Tuolugou deposit and other typical strata-bound Co-Cu-Au deposits have striking similarities in the geological features and metallogenic pattern of primary cobalt. All of them are syngenetic hydrothermal exhalative sedimentation in origin.
Robust Hybrid Control for Ballistic Missile Longitudinal Autopilot

This paper investigates the boost phase's longitudinal autopilot of a ballistic missile equipped with thrust vector control. The existing longitudinal autopilot employs time-invariant passive resistor-inductor-capacitor (RLC) network compensator as a control strategy, which does not take into account the time-varying missile dynamics. This may cause the closed-loop system instability in the presence of large disturbance and dynamics uncertainty. Therefore, the existing controller should be redesigned to achieve more stable vehicle response. In this paper, based on gain-scheduling adaptive control strategy, two different types of optimal controllers are proposed. The first controller is gain-scheduled optimal tuning-proportional-integral-derivative (PID) with actuator constraints, which supplies better response but requires a priori knowledge of the system dynamics. Moreover, the controller has oscillatory response in the presence of dynamic uncertainty. Taking this into account, gain-scheduled optimal linear quadratic (LQ) in conjunction with optimal tuning-compensator offers the greatest scope for controller improvement in the presence of dynamic uncertainty and large disturbance. The latter controller is tested through various scenarios for the validated nonlinear dynamic flight model of the real ballistic missile system with autopilot exposed to external disturbances.

A Study of the Law of Herbal Administration in Treating Lung-distension by TCM Physicians through History Using Cluster Analysis

Objective: To review the herbal drugs used most often for treating lung-distension by determining those used by physicians throughout history; to study their property, taste, and channel tropism; and to explore their compatibility. Methods: Historical prescriptions for treating lung-distension were collected and sorted. Property, taste and channel tropism were determined, and the law of herbal administration was determined by cluster analysis. Results: One hundred and ninety five prescriptions were found, involving 166 herbal drugs, with a total appearance frequency of 1296 drugs. The herbs involved 8 properties (total appearance frequency, 1296), 7 forms of taste (total appearance frequency, 1991) and involved all 12 regular channels (total appearance frequency, 3382). Sixteen herbal drugs were used most often and formed 4 cluster prescriptions: C1: Xing Ren (Semen Armeniacae Amarum), Gan Cao (Radix Glycyrrhizae), and Ban Xia (Rhizoma Pinelliae); C2: Gui Zhi (Ramulus Cinnamomi), Wu Wei Zi (Fructus Schisandrae), and Sheng Jiang (Rhizoma Zingiberis Recens); C3: Da Zao (Fructus Jujubae), Ma Huang (Herba Ephedrae), and Shi Gao (Gypsum Fibrosum); and C4: Chen Pi (Pericarpium Citri Reticulatae), Jie Geng (Radix Platycodi), Fu Ling (Poria), Sang Bai Pi (Cortex Mori), Xi Xin (Herba Asari), Gan Jiang (Rhizoma Zingiberis), and Bai Shao (Radix Paeoniae Alba). Conclusion: In treating lung-distension, phlegm retention has been traditionally considered the underlying pathology, emphasizing regulation of the lung and spleen as key and stressing patient nourishment and mental improvement. Prescriptions for lung-distension should be made with reference to the property, taste, channel tropism, and effectiveness of the chosen herbal drugs.
Gualou Xiebai Banxia Decoction (瓜蒌薤白半夏汤) Inhibits NF-kappa B-dependent Inflammation in Myocardial Ischemia-reperfusion Injury in Rats

Objective: To evaluate the myocardial protective effect of Gualou Xiebai Banxia decoction (瓜蒌薤白半夏汤GXBD) and explore the mechanisms of inhibition of NF-kappa B activation and blockade of inflammatory responses induced by ischemia-reperfusion in rats. Methods: Twenty-four Sprague Dawley (SD) rats were randomly divided into three groups. Rats in the treatment group received GXBD (13 g crude drug/kg) for three weeks, while rats in the model control and normal control groups received equal volumes of distilled water. On the 22nd day, rats in the ischemia-reperfusion (I/R) control and GXBD-treated groups underwent 30 min occlusion of the left anterior descending (LAD) coronary artery, followed by 120 min reperfusion. Electrocardiogram was recorded, and the activities of cardiac enzymes, cytokines, and NF-κB were assessed after I/R. Results: Compared with the I/R control group, GXBD treatment restored the activity of the specific myocardial-injury marker creatine kinase (CK) and lactate dehydrogenase (LDH), and inhibited the inflammatory response involving the nuclear factor-κB (NF-κB) pathway, including down-regulation of interleukin (IL)-1β and IL-6, and up-regulation of IL-10 gene expression. Conclusion: GXBD strongly reduced myocardial impairment in our I/R model, including inhibition of NF-κB activation and inflammatory cytokine responses.
