We report on the optical performance, structure and thermal stability of periodic multilayer films con- taining Zr and Al（lwt.-%Si） or Al（pure） layers designed for the use as extreme ultraviolet （EUV） high reflective mirrors in the range of 1~19 am. The comparison of A1/Zr （Al（lwt.-%Si）/Zr and Al（pure）/Zr） multilayers fabricated by direct-current magnetron sputtering shows that the optical and structural per- formances of two systems have much difference because of Si doped in A1. From the results of grazing incidence X-ray reflection （GIXR）, X-ray diffraction （XRD）, and EUV, the Si can disfavor the crystalliza- tion of AI and smooth the interface, consequently increase the reflectance of EUV in the Al（lwt.-%Si）/Zr systems. For the thermal stability of two systems, the first significant structural changes appear at 250 ~C. The interlayers are transformed from symmetrical to asymmetrical, where the Zr-on-A1 interlayers are thicker than Al-on-Zr interlayers. At 295 ~C for Al（pure）/Zr and 298 ~C for Al（lwt.-%Si）/Zr, the interfaces consist of amorphous Al-Zr alloy transform to polycrystalline Al-Zr alloy which can decrease the surface roughness and smooth the interfaces. Above 300 ~C, the interdiffusion becomes larger, which can enlarge the differences between Zr-on-Al and Al-on-Zr interlayers. Based on the analyses, the Si doped in Al cannot only influence the optical and structural performances of Al/Zr systems, but also impact the reaction temperatures in the annealing process.

Focal segmental glomerulosclerosis (FSGS) is characterized histologically by hyalinosis and sclerosis of glomeruli associated or not with podocyte involvement. The objective of our work was to clarify the epidemiological aspects and histological variants of FSGS in Côte d’Ivoire. Materials and Methods: This was a descriptive retrospective study, conducted from January 2015 to December 2019 using the renal biopsy registers (RB) of the Pathological Anatomy and Cytology departments of the Teaching Hospital of Cocody and Bouake in collaboration with the Nephrology Services of Côte d'Ivoire and the sub-region. The biopsies underwent conventional histopathology and/or immunofluorescence techniques. The parameters analyzed were: frequency, age, gender, proteinuria, biopsy indications and histological aspects and the different correlations between histological aspects and socio-demographic characteristics. Results: FSGS represented 58.1% (n = 104) of glomerular nephropathies. The average age of patients was 32.1 ± 13.3 years, with extremes of 13 and 70 years. The sex ratio was equal to 1. Nephrotic syndrome (68.9%), chronic renal failure (14.3%) and acute renal failure (10.1%) were the main indications for renal biopsy (RB). The mean proteinuria at the time of diagnosis was 4 ± 3.7 g/24 h. It was massive (3.5 g/24 h) in 42.3% of patients. FSGS was primary in 29.8% (n = 31) and secondary in 70.2% (n = 73) of patients, of which 27.9% (n = 35) was due to HIV. According to the Columbia classification, 62.5% NOS type was found;23.1% collapsing type;7.7% tip lesion type;4.8% cell type and 1.9% perihilary type. Conclusion: FSGS is a complex heterogeneous entity. It affects young people in our context with a homogeneous gender distribution. Understanding its histogenesis is essential for optimal patient management.

Background: Extracorporeal membrane oxygenation is a rescue life support technique used in life threatening conditions of refractory respiratory and/or cardiac distress. Indication for extracorporeal life support in children depends on age and varies from pulmonary to cardiac pathologies. In some cases, it may be used as a bridge to a therapeutic procedure. We described here the management of respiratory failure due to hemoptysis in a child with a Fontan circulation and veno-venous extracorporeal membrane oxygenation which served as a bridge to angio-embolization. Hemoptysis can be a life threatening condition which can lead to hypovolemic shock and impaired alveolar gas exchange. The latter can result in respiratory failure and consequent asphyxia. When hemoptysis occurs in a patient with a univentricular heart and a Fontan circulation, management of this clinical situation can be challenging due to the particular physiology of the latter. Total cavopulmonary connection is a palliative surgical repair whi

对各种类型的铝试件进行疲劳试验以研究组合片材对破损和未破损铝试件的增强效果,探讨加工过程和试件尺寸对疲劳性能的影响。对破损和未破损试件进行修补,比较了其疲劳强度与普通铝S-N曲线上相对应的值。研究显示:黏合剂的抗剪强度对试件的疲劳性能影响很大,尤其在最高荷载水平时。通过准静态试验和相应的数学模型可以获得黏合剂抗剪强度。当黏合剂最大剪应力与抗剪强度近似相等时,可观察到疲劳荷载下试件的早期破坏,很显然后者对修复结构疲劳响应有很大的影响。
