Shanxi Agricultural University is a university in Shanxi, China under the authority of the provincial government.It is located in the county town of Taigu , a fairly rural area with a population of about 40,000 people. The school was founded in 1907 as the Ming Hsien school by a group of missionaries from Oberlin College, including the financier H.H. Kung, the future husband of Soong Ai-ling, the eldest of the three Song sisters.More precisely, the Oberlin missionaries founded a primary school in Taigu in the 1880s. When he was still as boy, H.H. Kung became friends with the missionaries after they cured an eye disease that he suffered from. The missionaries were killed in the Boxer Rebellion during the summer of 1900, but Kung was sheltered by his family and survived. A few years later, now a young man, Kung was invited to continue his studies at Oberlin College. After graduating from Oberlin, he obtained his Masters degree at Yale and then returned to China.In 1907 Kung founded Ming Hsien high school in his hometown of Taigu. . Beginning in 1908, Oberlin began sending recent graduates to teach at Ming Hsien and support Kung's efforts under the auspices of the Oberlin-Shansi Memorial Association.In 1950, following the Communist victory in the civil war, Ming Hsien was taken over by the party, turned into a university, and renamed "Shansi Agricultural University." The American teachers from Oberlin were expelled and did not return until 1982, following China's "reform and opening."Primarily an agricultural university , the school also has departments in the arts, physical education and English language study. The university maintains connections with Oberlin Shansi, a non profit organization operating out of Oberlin College, engaging in cross-cultural and education exchange programs. Each year, the university hosts young English teachers who have recently graduated from Oberlin College.In addition to the Oberlin Shansi program, Shanxi Agricultural University also has established academic relations with universities and research institutions in Germany, Japan, Australia and Britain.

Although their high-cost and complex preparation technology processing have limited their applications in engineering areas, whiskers are being increasingly used as reinforcing materials for the aim of mechanical or thermal property improvement of other materials, such as polymers. Accordingly, the work of this paper proposes the preparation of magnesium hydroxide whiskers. And the magnesium hydroxide whiskers, whose length being about 30μm and its diameter being about 3μm, was prepared by hydrothermal conditions successfully. Besides, the effect of preparation technology, which includes the reaction temperature and reaction time, was discussed according to the results of XRD, TEM, and SEM. Moreover, the mechanism of the preparation of magnesium hydroxide whiskers was studied. © 2017 Trans Tech Publications, Switzerland.

Artificial neural net technology can reflect the relationship between the actual state development tendency and the state input signal. CaCO3 is the number one inorganic fillers in all inorganic materials used in the industry. And the continued developments of these related areas has focused research attention on the possibilities offered by CaCO3 nanocrystalline for its excellent characters. Accordingly, a three-layer structure back-propagation network model based on the non-linear relationship between the size of the CaCO3 nanocrystalline and the technological factors, such as reaction time, reaction temperature, raw material adding amount of Na2CO3 and CaCl2, was established in this paper. Moreover, in order to accelerate the converging rate and avoid the non-converging situation, the momentum terms are introduced. Besides, the variable learning speed is adopted. At the same time, the input variables were pretreated by using the main component analysis firstly. And the results show that the improved back propagation neural networks model is very efficient for predication of the CaCO3 nanocrystalline size. © 2017 Trans Tech Publications, Switzerland.

Based on qualitative and quantitative melissopalynological analyses, 19 Chinese honeys were classified by botanical origin to determine their floral sources. The honey samples were collected during 2010-2011 from the central region of Shanxi Province, North China. A diverse spectrum of 61 pollen types from 37 families was identified. Fourteen samples were classified as unifloral, whereas the remaining samples were multifloral. Bee-favoured families (occurring in more than 50% of the samples) included Caprifoliaceae (found in 10 samples), Laminaceae (10), Brassicaceae (12), Rosaceae (12), Moraceae (13), Rhamnaceae (15), Asteraceae (17), and Fabaceae (19). In the unifloral honeys, the predominant pollen types were Ziziphus jujuba (in 5 samples), Robinia pseudoacacia (3), Vitex negundo var. heterophylla (2), Sophora japonica (1), Ailanthus altissima (1), Asteraceae type (1), and Fabaceae type (1). The absolute pollen count (i.e., the number of pollen grains per 10 g honey sample) suggested that 13 samples belonged to Group I (<20,000 pollen grains), 4 to Group II (20,000-100,000), and 2 to Group III (100,000-500,000). The dominance of unifloral honeys without toxic pollen grains and the low value of the HDE/P ratio (i.e., honey dew elements/pollen grains from nectariferous plants) indicated that the honey samples are of good quality and suitable for human consumption. © 2012 Song et al.

Palmitoleate (cis-Δ9-16:1) shows numerous health benefits such as increased cell membrane fluidity, reduced inflammation, protection of the cardiovascular system, and inhibition of oncogenesis. Plant oils containing this unusual fatty acid can also be sustainable feedstocks for producing industrially important and high-demand 1-octene. Vegetable oils rich in palmitoleate are the ideal candidates for biodiesel production. Several wild plants are known that can synthesize high levels of palmitoleate in seeds. However, low yields and poor agronomic characteristics of these plants limit their commercialization. Metabolic engineering has been developed to create oilseed crops that accumulate high levels of palmitoleate or other unusual fatty acids, and significant advances have been made recently in this field, particularly using the model plant Arabidopsis as the host. The engineered targets for enhancing palmitoleate synthesis include overexpression of Δ9 desaturase from mammals, yeast, fungi, and plants, down-regulating KASII, coexpression of an ACP-Δ9 desaturase in plastids and CoA-Δ9 desaturase in endoplasmic reticulum (ER), and optimizing the metabolic flux into triacylglycerols (TAGs). This review will mainly describe the recent progress towards producing palmitoleate in transgenic plants by metabolic engineering along with our current understanding of palmitoleate biosynthesis and its regulation, as well as highlighting the bottlenecks that require additional investigation by combining lipidomics, transgenics and other "-omics" tools. A brief review of reported health benefits and non-food uses of palmitoleate will also be covered. © 2012 Elsevier Ltd. All rights reserved.

The coordination of plant cell division and expansion controls plant morphogenesis, development, and growth. Cyclin-dependent kinases (CDKs) are not only key regulators of cell division but also play an important role in cell differentiation. In plants, CDK activity is modulated by the binding of INHIBITOR OF CDK/KIP-RELATED PROTEIN (ICK/KRP). Previously, ICK2/KRP2 has been shown to mediate auxin responses in lateral root initiation. Here are analysed the roles of all ICK/KRP genes in root growth. Analysis of ick/krp null-mutants revealed that only ick3/krp5 was affected in primary root growth. ICK3/KRP5 is strongly expressed in the root apical meristem (RAM), with lower expression in the expansion zone. ick3/krp5 roots grow more slowly than wildtype controls, and this results not from reduction of division in the proliferative region of the RAM but rather reduced expansion as cells exit the meristem. This leads to shorter final cell lengths in different tissues of the ick3/krp5 mutant root, particularly the epidermal non-hair cells, and this reduction in cell size correlates with reduced endoreduplication. Loss of ICK3/KRP5 also leads to delayed germination and in the mature embryo ICK3/KRP5 is specifically expressed in the transition zone between root and hypocotyl. Cells in the transition zone were smaller in the ick3/krp5 mutant, despite the absence of endoreduplication in the embryo suggesting a direct effect of ICK3/KRP5 on cell growth. It is concluded that ICK3/KRP5 is a positive regulator of both cell growth and endoreduplication. © 2013 The Authors.

The pressure distribution in balance chamber is the key technology that centrifugal pump with floating impeller balances axial force automatically. Based on two important parameters, ring seal diameter of impeller and area of balancing hole, different combination groups were formed to construct the 3-D model of 3BA-6 single stage single suction centrifugal pump. Through the numerical simulation after the model by computational fluid dynamics (CFD) theory, the pressure distributions in balance chamber were obtained. Then axial compound stress was calculated and balance analysis was made. Simultaneously, the pressure in balance chamber was tested practically. The results show that axial force of centrifugal pump with floating impeller can be balanced under the condition that rate of flow amounted to 0.002~0.006 m3/s, and when k=1.2, A=7.07 mm2. And the pressure in balance chamber is 13%~20% of lift corresponding operating condition. Simulated values are closely matched with the measured value, which proved the appropriateness of numerical simulation. The practical significance is supplied by using CFD technology and changing parameters to design the most proper structure. © 2011 Chin. Soc. for Elec. Eng.

In order to improve the productivity and the production efficiency of the greenhouse, the canopy photosynthesis model of tomato - one of the main species cultivated in greenhouse was developed based on simple leaf photosynthesis, after the comprehensive consideration of leaf area index and light density distribution in greenhouse. At the same time, the model has considered the influence of the environment (temperature, CO 2 concentration and moisture). Utilizing the test data materials to evaluate the model, the simulation result shows that the relative error of photosynthetic rate between observed value(except for 0) and simulated value is 0∼10.0% and they had good consistency. The model developed in this study could give satisfactory predictions of the variation of photosynthetic rate, which established the foundation for the next study on the effects of environmental factor on the growth and further automatic control of greenhouse tomato production. © 2010 Published by Elsevier Ltd.

Sedimentary samples from 28 sites throughout the Fenhe reservoir and upstream watershed in China were measured, to study the relationships between PAHs and PCBs as well as perform quantitative source apportionment of toxicity. The distributions of ∑16PAHs and ∑123PCBs showed high correlation. The ∑7C-PAHs (total concentrations of seven carcinogenic PAHs) varied from 87.7 to 2005.0ngg-1dw, and the ∑6DL-PCBs (total concentrations of six dioxin-like PCB congeners) were n.d.-5.96ngg-1dw. Toxicity and biological risk were assessed using toxic equivalent quantity (TEQ) and sediment quality guideline quotient (SQGQ). The BaP played the dominant role for TEQPAH at most sites (37.17-89.40%), although the CHR showed the highest concentration level. PCB-81 contributed the highest TEQPCB. High correlations were observed between ∑16PAHs and ∑7C-PAHs, ∑123PCBs and ∑6DL-PCBs, ∑7C-PAHs and ∑6DL-PCBs as well as TEQPAH and TEQPCB. Furthermore, quantitative source apportionments for PAHs concentrations and TEQ were carried out, combining the positive matrix factorization (PMF) with the formula of TEQ. For most sites, the vehicular sources were the largest contributors to TEQPAH (46.58%), while coal combustion sources were the highest contributor for PAHs concentrations (43.31%). The relatively higher correlations between PCBs and contributions of coal combustion to PAHs might imply the similar distribution of industrial sources for PAHs and PCBs. © 2013 Elsevier B.V.

The inlet setting angle of a space guide vane is an important geometric parameter that affects performance of a submersible pump. Based on theoretical analysis, space guide vanes with the same impeller and different inlet setting angles were formed to construct the 3-D model of the submersible pump. Through the numerical simulation after the model by computational fluid dynamics (CFD) theory, the performance curves are obtained. Then influence of inlet setting angle variation on submersible pump performances was analyzed. Simultaneously, the simulation results are tested. The results show that the optimum operating point of a submersible pump is shifted to the large flow rate under the condition that the inlet setting angle of the space guide vane increases. The efficiency is 75%~81% and the flow rate amounts to 95~125 m 3/h under the condition that the inlet setting angle of the space guide vane amounts to 27°~30°. Simulated values are closely matched with the measured ones. Variation of inlet setting angles of the space guide vane can maintain a high efficiency of submersible pumps under certain operating conditions, which provides a new way of increasing specifications and expanding application scopes. © 2012 Chinese Society for Electrical Engineering.

Silver nanoparticles were successfully synthesized from aqueous silver nitrate through a simple green route using the extract of Mango peel as a reducing as well as capping agent. The possible biochemical mechanism leading to the formation of silver nanoparticles was studied using FTIR. The various operational parameters were evaluated for biosynthesis process. The results obtained from UV-vis spectrum, X-ray diffraction (XRD), and Transmission electron microscope (TEM) revealed that the biosynthesis of silver nanoparticles are in the size range of 7-27. nm and is crystallized in face centered cubic symmetry. Further, the antibacterial application of these biologically synthesized silver nanoparticles loaded onto non-woven fabrics has also been discussed. The results show that non-woven fabrics loaded with biosynthesis silver nanoparticles displayed excellent antibacterial activity. © 2013 Elsevier B.V.
