The Wind River Indian Reservation undertook the development of an agricultural resource management plan in 2015. The reservation is 8903 *** of which 63% is in crop and grazing lands. This project’s aim was to create a community-based integrated plan. A series of community meetings identified 83 issues and topics relating to agricultural development on the reservation. Using information from community meetings, the final agricultural resource management plan consists of 9 major elements, with 12 goals, 46 objectives and 88 policies. Three key issues are addressed in the plan: provide the reservation with a plan that leads to self-management of their agricultural resources;integrate the major agricultural elements as defined by the community into policies;and, create a governance structure that fosters agricultural development into the future.

We investigate the bound states of the Yukawa potential V(r)=-λexp(-αr)/r, using different algorithms: solving the Schrodinger equation numerically and our Monte Carlo Hamiltonian approach. There is a critical α = αC, above which no bound state exists. We study the relation between αC and A for various angular momentum quantum number l. and find in atomic units, αC(l) = λ[A1 exp(-l/b1) + A2exp(-l/b2)], with A1 = 1.020(18), b1 = 0.443(14), A2 = 0.170(17), and b2 = 2.490(180).

We investigate the effects of a movable mirror (cantilever) of an optical cavity on the superradiant light scattering from a bose-Einstein condensate (bec. in an optical lattice. We show that the mirror motion has a dynamic dispersive effect on the cavity-pump detuning. Varying the intensity of the pump beam, one can switch between the pure superradiant regime and the bragg scattering regime. The mechanical frequency of the mirror strongly influences the time interval between two bragg peaks. We find that when the system is in the resolved side band regime for mirror cooling, the superradiant scattering is enhanced due to coherent energy transfer from the mechanical mirror mode to the cavity field mode.

Motivated by the experimental realization of Dicke model in optical cavities, we model an optomechanical system consisting of two-level bec.atoms with transverse pumping. We investigate the transition from normal and inverted state to the superradiant phase through a detailed study of the phase portraits of the system. The rich phase portraits generated by analytical arguments display two types of superradiant phases, regions of coexistence and some portion determining the persistent oscillations. We study the time evolution of the system from any phase and discuss the role of mirror frequency in reaching their attractors. Further, we add an external mechanical pump to the mirror which is capable of changing the mirror frequency through radiation pressure and study the impact of the pump on the phase portraits and the dynamics of the system. We find the external mirror frequency changing the phase portraits and even shifting the critical transition point, thereby predicting a system with controllable phase transition.

目的观察WWOX基因转染细胞对卵巢癌PE01细胞黏附能力的影响，并探讨其作用机制。方法利用已构建的WWOX转染细胞、质粒转染细胞及PE01母细胞进行黏附实验，观察不同细胞对纤粘连蛋白（Fn）介导的细胞黏附性。利用整合素仅和b介导的细胞黏附实验，筛选出与卵巢癌细胞黏附有关的整合素。利用筛选出的整合素，进行封闭卵巢癌细胞表面整合素的功能实验，流式细胞检测整合素的表达情况。结果在Fn包被的培养孔中培养2h后，WWOX转染细胞对Fn的细胞黏附性明显低于PE01母细胞和质粒转染细胞（均P〈0．01）。在质粒转染细胞中，整合素以和α3的表达明显高于WWOX转染细胞（均P〈0．05），而整合素β1、β2的表达无明显变化（P〉0．05）；封闭整合素α3后，所有转染细胞对Fn的黏附性明显降低，与非特异性抗体IgG相比，差异有统计学意义（P〈0．05），而封闭整合素以后，与非特异性抗体IgG相比，差异无统计学意义（P〉0．05）。流式细胞检测结果显示，在WWOX转染细胞中，整合素013的表达明显低于质粒转染细胞（P〈0，05）。结论WWOX基因通过调节卵巢癌细胞与细胞外基质的相互作用，降低整合素α3活性，进而降低卵巢癌细胞对Fn介导的黏附性。

The feasibility of semi solid processing of hypereutectic A390 alloys using a novel rheoforming process was investigated. A combination of the swirl enthalpy equilibration device （SEED） process, isothermal holding using insulation and addition of solid alloy during swirling was introduced as a novel method to improve the processability of semi solid slurry. The effects of isothermal holding and the addition of solid alloy on the temperature gradient between the centre and the wall and on the formation of a（Al） particles were examined. In additional tests, phosphorus and strontium were added to the molten metal to refine the primary and eutectic silicon structure to facilitate semi solid processing. The results show that the combination of the SEED process with two additional processing steps can produce semi-solid A390 alloys that can be rheoprocessed. The microstructure reveals an adequate amount of non-dendritic a（Al） globules surrounded by liquid, which greatly improves the processability of semi-solid slurry.
