Field an experiment was carried out in the farms of Agriculture and forestry academy at University in Nineveh. The research was conducted to investigate a practical study for the effect of four forward speeds (1.9, 2.6, 3.8 and 4.7 km/hr.) and three acceleration direction of axes lateral, longitudinal and vertical, and two types machines control (Mower and Rotovators) on the vibrations transferred to the steering wheel horticulture tractor type (Goldoni). The vibration points on the handgrip were calculated and tested. Root mean square acceleration (RMS), given in m/sec2, was calculated. Results showed increased acceleration vibration of the three directions (longitudinal, lateral and vertical) transferred to the steering wheel tractor by increased forward speed. The Mower score recorded the highest acceleration vibration for the three directions of Rotovators. The levels of vibration emitted from tractor to hand an operator during the experiment was high comparing with standard mechanical vibration. Handgrip vibration intensity in the vertical direction is bigger than the lateral and longitudinal direction. The total vibration evaluating was denoted as the square root mean of the three sum value (lateral, longitudinal and vertical) directions. The paper purpose was measuring and analyzing vibration level transferred to the steering wheel and reduces the machine vibration. This paper is helpful for design in order to increase the develop safety systems in easy and economical way.

This paper for the first time improved a Robust Multi-Output machine learning regression model for seismic hazard zoning of Turkey, Iraq and Iran using constructed 3-D shear-wave velocity(Vs), seismic tomography dataset model for the crust and uppermost mantle beneath the study area. The focus of this paper’s opportunity is to develop a scientific framework leveraging machine learning that will ultimately provide the rapid and more complete characterization of earthquake properties. This work can be targeted at improving the seismic hazard zones system ability to detect and associate seismic signals, or at estimating other seismic characteristics(crust acceleration and crust energy) while traditionally, methods cannot monitor the earthquakes system. This work has derived some physical equations for extraction of many variables as inputs for our developed machine learning model based on a reliable understanding of the tomography data to physical variables by preparing huge dataset from different physical conditions of crust. We have extracted the velocity values of the shear waves from the original NETCDF file, which contains the S velocity values for every one km of the depths of the crust for the study area from one km down to the uppermost mantle beneath the Middle East. For the first time, this study calculated new seismic hazard parameter called Peak Crust Acceleration(PCA) for seismic hazard analysis by considering the transmitted initial seismic energy through the Earthy wrote in python language ’s crust layers from hypocenter.

AIM： To validate gastric anti-ulcer properties of Rocket ＂Eruca sativa＂ on experimentally-induced gastric secretion and ulceration in albino rats. METHODS： Gastric acid secretion studies were undertaken using pylorus-ligated rats. Gastric lesions in the rats were induced by noxious chemicals including ethanol, strong alkalis, indomethacin and hypothermic restraint stress. The levels of gastric wall mucus （GWM）, nonprotein sulfhydryls （NP-SH） and malondialdehyde （MDA） were also measured in the glandular stomach of rats following ethanol administration. The gastric tissue was also examined histologically. The extract was used in two doses （250 and 500 mg/kg body weight） in all experiments. RESULTS： In pylorus-ligated Shay rats, the ethanolic extract of Rocket ＂Eruca sativa L.＂（EER） significantly and dose-dependently reduced the basal gastric acid secretion, titratable acidity and ruminal ulceration. Rocket extract significantly attenuated gastric ulceration induced by necrotizing agents （80% ethanol, 0.2 mol/L NaOH, 25% NaCl）, indomethacin and hypothermic restraint stress. The anti-ulcer effect was further confirmed histologically. On the other hand, the extract significantly replenished GWM and NP-SH levels, as well as the MDA level significantly reduced by extract pretreatment. CONCLUSION： Rocket extract possesses antisecretory, cytoprotective, and anti-ulcer activities against experimentally-induced gastric lesions. The anti-ulcer effect is possibly through prostaglandinmediated activity and/or through its anti-secretory and antioxidant properties.

Vitiligo is a common pigmentary disorder. Many studies across decades and all over the world have attempted to illustrate the pathogenesis behind it; however, the pathogenesis of vitiligo remains elusive. This review article, we present the findings behind the most and updated theories behind this psychologically debilitating and disfiguring disease. The discussion begun with the role of genetic predisposition followed by neural theory first proposed in the 1950 s. Wehighlight the autoimmune hypothesis, followed by the reactive oxygen species model, zinc-α2-glycoprotein deficiency hypothesis, viral theory, intrinsic theory and biochemical, molecular and cellular alterations accounting for loss of functioning melanocytes in vitiligo. Many theories were elaborated to clarify vitiligo pathogenesis. It is a multifactorial disease involving the interplay of several factors. Future research is needed to clarify the interaction of these factors for better understanding of vitiligo pathogenesis and subsequent successful treatment.

AIM： To assess the objective and subjective results of a two-stage procedure for management of keratoconus： clear lensectomy with aspherical intraocular lens（IOL） implantation followed by wave front-guided photorefractive keratotomy（WFG-PRK）.METHODS： This prospective interventional non-randomized study included patients aged 35 years old or more with grade I and II stable keratoconus, a clear visual axis, minimal corneal thickness（MCT） 420 μm or more and average keratometric reading（K） less than 54 diopter（D）. Refraction of all selected eyes should be-8.00 D sphere or more with less than-6.00 D cylinder and could be corrected two lines or more with spectacles or contact lenses. All studied eyes underwent a two-stage approach treatment： first refractive lens exchange and aspherical IOL implantation followed, after at least 3 mo, by WFGPRK. Pre and postoperative complete ophthalmological examination were performed. Topographical, visual and aberrometric results were recorded and evaluated during 6 mo follow up period. Moreover, patient satisfaction and other subjective outcomes were also ***： The 13 eyes of 11 patients diagnosed with stable keratoconus and aged from 39 to 49 y（42.4±6.2 y） were enrolled in the study. At baseline, 8 eyes had grade I and 5 eyes had grade II keratoconus. The manifest sphere was-10.3±4.2 D（ranged from-8.0 to-14.0 D） and the manifest cylinder was-4.2±1.2 D（ranged from-1.75 to-5.50 D）. After the two-stage procedure, sphere and cylinder reduced significantly to-0.43±0.22 D and-1.3±0.72 D respectively（P〈0.001）. There was also a highly significant improvement in the mean uncorrected distance visual acuity（UDVA） from logMAR 1.41±0.49 preoperatively to 0.51±0.16 postoperatively（P〈0.001） and the mean corrected distance visual acuity（CDVA） from 0.76±0.24 preoperatively to 0.49±0.13 after the operation（P〈0.001）. All aberrometric and mesopic vision parameters and most of the topographical indices demonstrated highly significant improveme

四川盆地位于中国西南部,经历了复杂的构造演化过程,也是中国油气资源最为丰富的盆地之一。四川盆地东部褶皱带(简称“川东褶皱带”)以发育隔档式褶皱为主要构造特征,构造变形较为复杂。同时,在川东褶皱带,发现了三套塑性滑脱层分别为中下寒武统膏盐岩、志留系泥岩、中下三叠统膏盐岩。以这三套滑脱层为界可将川东地层划分为三套构造层:深部寒武系-奥陶系构造层(以中下寒武统膏盐岩滑脱层为底界),中部石炭系-二叠系构造层(以志留系泥岩滑脱层为底界)和浅部中生界构造层(以中下三叠统膏盐岩滑脱层为底界)。三套滑脱层将川东地区垂向上划分为上中、下三套构造层,各构造层之间的构造变形具有显著差异。尽管前人已经针对川东褶皱带开展了大量的研究工作并取得了一定的认识,然而关于这三套滑脱层对川东褶皱带构造变形过程所起到的控制作用尚待明确。本文在地震解译和构造平衡恢复的基础之上,结合多滑脱层砂箱物理模拟实验开展研究,重点探讨川东地区多套滑脱层对川东褶皱带构造变形的控制作用。首先,通过地震解译和构造平衡恢复(Midland Valley),刻画出川东褶皱带的构造特征,其构造平衡恢复结果表明:川东褶皱带最大缩短量为26.13km(缩短率约为20.34%),最大缩短速率为0.090 mm/a。在此基础上,根据川东褶皱带地层发育特点和构造特征,设置了五组构造物理模拟实验,通过控制滑脱层数量、滑脱层厚度、缩短量与缩短速率等参数,模拟和研究川东褶皱带构造变形的运动学过程,并定量评价了构造变形的过程。实验结果表明,滑脱层配置(数量、垂向分布等)和变形速率对川东多套滑脱层发育区的构造变形样式及构造演化过程具有重要的控制作用:(1)深部滑脱层的拆离效果显著强于浅部滑脱层,导致垂向上深部构造层内的构造变形差异性高于浅部构造层(2)缩短速率减小时,滑脱层的拆离效果明显增加,各构造层变形样式的差异性也随之增强。结合地震资料和砂箱模拟实验结果分析,推测川东地区在早期弱挤压变形阶段(缩短速率较低),其三套滑脱层的拆离作用明显,以发育滑脱褶皱及小型调节断层为主要构造变形特征,同时各构造层变形特征产生了明显的垂向差异性;在后期强烈挤压变形阶段(缩短速率快速提升),缩短速率限制了各滑脱层的拆离作用,各构造层以发育高陡逆冲断层和反冲断层为主,变形特征趋于一致。
