Problems with mites : Sometimes a mealworm colony gets infested by grain mites ( Acarus sp .) The mites may come from the mealworm supplier, in bran, or litter from poultry production, and may infest a colony that has been around for a long period of time.

问题螨 ：有时，一个mealworm殖民地获得布满粮食螨螨可能来自mealworm供应商，在麦麸，或乱抛垃圾，从家禽生产，并有可能滋生一个殖民地，我们一直在相当长的时期时间。

The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

确定了粗粒土与结构接触面厚度约为5～6倍的平均粒径，首次揭示了接触面的细观结构异向性以及由此所引起的宏观剪切异向性，发现了在单调和往返剪切荷载作用下土颗粒破碎和剪切压密两种物态变化机制共同支配着接触面力学性质的变化，通过细观分析证实了接触面的变形可分解为一般同时发生的土与结构交界面上的滑移变形以及结构面位移约束范围之内土体本身的剪切变形两部分，观测到接触面受剪时表现出明显的相对法向位移，并可分解为可逆性和不可逆性两个分量；(4)建立了第一个能够统一地描述单调与往返剪切特性、剪应变与体应变耦合特性、细观结构和宏观剪切异向性以及土颗粒破碎等物态变化特性的土与结构接触面弹塑性损伤本构数学模型，并采用多种法向边界条件复杂加载路径的试验成果验证了新模型的合理性和有效性；(5)提出了新模型的二、三维有限元格式并结合实际边值问题进行了应用计算分析，比较了不同接触面本构模型对计算结果的影响，证实了新模型及其有限元格式不仅能够合理地描述土与结构接触面的主要力学特性，还能够较好地反映土体与结构物在接触面处的滑移、脱开等不连续现象。

Results show 1 the total water requirement of the crops in the Jinghe Watershed is 740543.20×10^4 m^3, accounting for 41.58% of the total water requirement of the region; 2 of the two major groups of crops, grain crops are higher than cash crops in water requirement quotas; and among specific crops, vegetables, melons, rice and cotton are higher and sunflower, potato and benne are lower than other crops; 3 water requirement per hectare varies from county to county with the highest being 5682m^3hm^(-2), in Jingyang County, and the lowest 4022 m^3hm^(-2) in Dingbian County, averaged to 4 583 m^3hm^(-2), but the water requirement quota of a crop does not vary with the county, so calculation of water requirement quota of a county is closely related to its cropping structure; and 4 because of serious waste of water in farming, the actual water consumption in agriculture in the region is much higher than the calculated crop water requirement.

结果表明，泾河流域农作物需水量总计740543.20万立方公尺，农作物需水占总需水量的比例较高，为41.58%。粮食作物需水定额较经济作物高；就具体作物而言，菜、瓜类、水稻、棉花等需水定额较高，向日葵、薯类、胡麻等较低。各县单位面积需水量差异较大，平均值为4583立方公尺hm^(-2)；泾阳县最高，为5682立方公尺hm^(-2)，定边县最低，为4022立方公尺hm^(-2)。由于事先设定大多数作物的需水定额不随县的改变而改变，因此需水量与作物结构密切相关。农业用水浪费严重，使泾河流域农作物实际用水量远高于需水量的理论计算值。

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340～1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230～2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ～20and the lake returned to high level during 2330～930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.

Comparison of the coding regions of BH1-BH4 genes showed that BH1 had a lower sequence identity to other previously published B-hordeins than the other three B-hordeins obtained in this study. BH1 was then cloned in a bacterial expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid produced a 28.15 kDa protein in Escherichia coli. The potential value of B-hordein genes in grain quality improvement of hull-less barley has been discussed.

A neighbor next to our house, i saw he is brushing his car again today morning, as matter of fact, his car is clearest in this community since he brought it, i don't want to say more about the weather in Beijing, ourbodies can see it, the sand and some tiny grain in the air, these all would upload into the weather forecast everyday, so, the sand is in everycornor, yet, his car is very clear, even no a little bit sand in the surface of car, that's as if a poor beautiful girl, dresses up a pretty cloth, and feeling good inside when somebody say you are beauty as a car-host.
