Baiguoyuan silver-vanadium deposit is generally thought to be of sedimentary-diagenetic origin. Based on the characteristics of barites, it is suggested that hydrothermal transformation has been involved in mineralization. The barites in black shale can be grouped into irregular ones which were formed during early diagenesis and tabular ones which were formed during late diagenesis. The tabular barites are replaced by pyrite and have formed a regular girdle around them. PIXE analysis states that Ag is greatly concentrated in pyrite replacement girdle. The girdle is the product of hydrothermal transformation. The transformation is one of the main mineralization stages of Baiguoyuan deposit.

In order to improve ride comfort and handling performance of the vehicle, an adaptive hybrid control algorithm is proposed for semi-active suspension systems. The virtues of sky-hook is combined with ground-hook control strategies and a more suitable compromise for the suspension systems is chosen. The hybrid coefficient is tuned according to the longitudinal and lateral acceleration so as to improve the vehicle stability especially in high speed conditions. Damping continuous adjustable absorber is used to continuously control the damping force so as to eliminate the damping force jerk instead of traditional on-off control policy. Based on suspension stroke measured by sensors, unscented Kalman filter is designed to estimate the suspension states in real-time for the realization of hybrid control, which improves the robustness of the control strategy and is adaptive to different types of road profiles. Finally, the proposed control algorithm is validated under the following two typical road profiles: half-sine speed bump road and the random road. The simulation results indicate that the hybrid control algorithm could offer a good coordination between ride comfort and handling of the vehicle.

: By means of kerogen purification, the proton induced X-ray emission (PIXE) and instrumental neutron activation analysis (INAA), the authors have studied the organic/inorganic occurrence modes of the metallic elements of the Baiguoyuan silver-vanadium deposit hosted in black shale in Hubei Province, China. The result shows that Au, Hg and Ta have a strong tendency to occur organically, with more than 70% of these elements being associated organically. Se, Ga, Ag and Hf are partly associated with organic matter, with more than 20% of them occurring organically. Compared with the above elements, Zn, Cu, As and Sb are weakly associated organically, and tend to be enriched in kerogen. However, Mn, Th, U, V, Co, Cr, AI, Fe and Sc usually occur inorganically. Of the rare earth elements (REE), La, Ce, Tb, Dy, Yb and Lu have stronger ability to be associated with organic matter than Sm and Eu.

BACKGROUND Takayasu arteritis is a rare but intractable chronic disease in young female patients. Percutaneous transluminal angioplasty of the involved renal arteries has been reported;however, few studies have reported the use of drug coated balloon angioplasty in the treatment of Takayasu arteritis. We aimed to demonstrate five young female patients who presented with a history of hypertension due to Takayasu arteritis. CASE SUMMARY From April 2017 to October 2018, five female patients were diagnosed with hypertension due to Takayasu arteritis by computed tomography angiography (CTA) and laboratory tests. Four patients had a complaint of headache with or without dizziness, and one patient showed no symptom. There was no significant family or past history of hypertension or kidney disease, and the physical examinations were almost normal on admission. We performed a treatment by drug coated balloon angioplasty. Blood pressure decreased dramatically in all patients after balloon angioplasty, and the patency of treated renal artery was demonstrated with CTA over 5 months after the angioplasty procedure. CONCLUSION Drug coated balloon angioplasty is safe and effective for renal artery stenosis due to Takayasu arteritis. A prospective study with a larger sample size is necessary to further demonstrate the effectiveness of the treatment.

塔里木盆地天山南地区古隆起周缘砂岩储层发育的主控因素及致密化成因一直制约着该区的增储上产。综合利用薄片和阴极发光观察、物性测试、压汞分析等方法对下白垩统舒善河组-巴西盖组砂岩储层特征进行了研究,明确了制约储层物性发育的主控因素。研究表明:研究区目的层的孔隙度φ多<10%,渗透率k<1×10^(-3)μm^(2),是典型的致密砂岩储层,其中辫状河三角洲相砂岩储层的物性和孔隙结构均最好(φ=12.3%,k=60.4×10^(-3)μm^(2)),扇三角洲相砂岩次之(φ=6.9%,k=1.9×10^(-3)μm^(2)),滩坝相砂岩最差(φ=6.7%,k=0.34×10^(-3)μm^(2));古隆起的演化控制了沉积相的差异,同时也影响了砂岩的成岩作用,辫状河三角洲和扇三角洲沉积环境水动力较强,砂岩颗粒较粗,受胶结作用弱,因此孔隙度和渗透率较高;滩坝相砂岩沉积时远离陆源输入,颗粒较细,水下古隆起的发育在成岩阶段控制了其较高含量的碳酸盐胶结物的形成,堵塞孔喉,显著降低砂岩储层物性,导致砂岩呈现致密化。研究成果可以为天山南地区下白垩统致密油气的勘探开发提供参考。

The coadsorption of cyclohexanone and oxygen on Pt(111) has been investigated by HREELS and TDS. At 205 K the presence of oxygen induces an "extra" red\|shift of the C--O stretching of coadsorbed cyclohexanone. heating this coadsorbed surface from 205 to 250 K leads to further dehydrogenation to form intermediate species and to complete disappearance of the C--O stretching band. Above 300 K, the molecule rings of dehydrogenation species cleave to form hydrocarbon fragments and CO molecules which directly desorb into the vacuum or react with preadsorbed oxygen to produce CO\-2 which leave the surface immediately. TDS results provide further evidence that the preadsorbed oxygen promotes the decomposition of cyclohexanone.
