Combine harvesters are important in that grain and legumes directly affect the production *** the other hand,it forms an important branch of the agricultural machinery *** are many unknown constraints on machines when harvesting with a combine harvester,including the noise and vibration that occur in the combine harvester *** study aims to analyze noise and vibration in conventional combine harvesters using *** accelerometers were installed on each side of the concave and two microphones were used to register the noise of the threshing *** result showed that effects of machine speeds(3.5 km/h,4.5 km/h and 5.5 km/h)and rotor speeds(950 r/min,850 r/min and 950 r/min)were significantly important for the mean range values of the left and right accelerometer in the X,Y and Z *** machine’s speed and rotor speed were not significantly important for the mean range values of the left and right microphones.

Introduction: Oncocytic neoplasms of the adrenal cortex are extremely rare and are usually nonfunctioning. Only a little more than fifty cases have been described in the literature. Case Presentation: We report the case of an adrenocortical oncocytic neoplasm with malignant potential in a 21-year-old female with co-secrete testosterone and cortisol. The patient had been operated of adrenal mass. Fallowing operation, the Cushing’s syndrome and high testosterone levels resolved. Conclusion: In our knowledge this is the first case in the l?terature which co-secret cortizol and testosterone in malign oncystoma.

联合收割机的重要性在于粮食和豆类作物直接影响生产经济。另一方面,它也形成了农业机械领域的一个重要分支。联合收割机在运行时,存在许多未知的约束条件,包括脱粒机中产生的噪声和振动。该研究旨在利用传感器分析传统联合收割机的噪音与振动。在凹面的两侧分别安装了两个加速度计,再用两个麦克风记录脱粒过程中的噪音。结果表明,机械转速(3.5 km/h、4.5 km/h和5.5 km/h)和转子转速(950 r/min、850 r/min和950 r/min)对左右加速度计在X、Y和Z方向上的平均量程值有显著影响。机器速度和转子速度对左右麦克风的平均范围值影响不大。

In the present paper, we derive some third-order differential subordination results for analytic functions in the open unit disk, using the operator Bcκf by means of normalized form of the generalized Bessel functions of the first kind, which is defined as z（Bκ＋1^c f（z））′= κBκ^c f（z）-（κ- 1）Bκ＋1^c f（z）,where b, c, p ∈ C and κ = p ＋（b ＋ 1）/2 ∈ C ／ Z0^-（Z0^-= {0,-1,-2, … }）. The results are obtained by considering suitable classes of admissible functions. Various known or new special cases of our main results are also pointed out.
