摘要:
一段时间没出去参加新车发布会了,去到现场有媒体同行看到我带着相机,就打趣的跟我说:"唉呦,现在还拿相机参加新车发布会,你也算是Old School的代表了啊!"确实,我承认目前有些手机的拍照功能超级强,整出来的照片甚至比相机拍的还要专业,带相机上发布会有没必要性值得商榷,但不可否认的是,手机的镜头小,很多拍摄出来的图片都是靠强大软件调修,与相机大镜头先天光学优势拍摄出来的图片就是有所不同……

摘要:
The global population is aging,and so the number of older cirrhotic patients is increasing.Older patients are characterised by a risk of frailty and comorbidities,and age is a risk factor for mortality in cirrhotic patients.The incidence of nonalcoholic fatty liver disease as an aetiology of cirrhosis is increasing,while that of chronic viral hepatitis is decreasing.Also,cirrhosis is frequently idiopathic.The management of portal hypertension in older cirrhotic patients is similar to that in younger patients,despite the greater risk of treatment-related adverse events of the former.The prevalence of hepatocellular carcinoma increases with age,but its treatment is unaffected.Liver transplantation is generally recommended for patients<70 years of age.Despite the increasing prevalence of cirrhosis in older people,little data are available and few recommendations have been proposed.This review suggests that comorbidities have a considerable impact on older cirrhotic patients.

摘要:
The objective of this study was to describe the state of the scene of senile dementia in an intra-institutional environment in the city of Lubumbashi. We conducted a descriptive cross-sectional study, over a period of three months, from February 20 to May 20, 2016. The study population is made up of the residents of the 9 retirement institutions for senior citizens (old people’s home) which counts the city of Lubumbashi. Participation was voluntary with informed consent duly signed by the patient. The probable cases of dementia were detected through the CSI-D and the 5-word test. A predominance of Alzheimer’s was noted (76.92%) and most of them were widowed (69.23%). The mean age of the dementia population was 76.46 ± 9.87 years, while (69.23%) of the patients were out of school. In (23.08%) cases demented patients were male, with a sex ratio of 0.3. Nearly (46.15%) of the demented were drinking. It appears that (69.23%) of the dementias were hypertensive. There are associations between different risk factors and the presence of dementias. Alcohol with an OR (Odd Ratio) = 0.08 (95% CI [0.01 - 0.72], p < 0.05). In our environment, our results indicate a different situation with a much higher prevalence.

摘要:
Ali, a 53-year-old man, lives with his family in a Saint-Camille Paspanga center for leprosy located on the outskirts of Ouagadougou3, Burkina Faso. The land is flat and bare and the main industries are agriculture and animal breeding4. Given5 the terrain6, people in the area face the challenges of bad accessibility7 due to the poor condition of the roads, lack of electricity and difficulty in accessing8 clean water.

摘要:
The volcanic tuffs of Senegal-Oriental in Mako area are produced during a calc-alkaline volcanism which occurs in this region and which is dated from about 2.3 - 1.95 Ga. Despite their altered appearance, the X-Ray diffractions show mineral paragenesis: Quartz-Kaolinite-Illite and an important amorphous phase. On the Ternary Keil-Rankin diagram for the CaO-SiO2-Al2O3 the volcanic tuffs of Mako area are situated between pozzolan and the fly ash. The difference between silica and lime is greater than 34% in these volcanic tuffs. In this study, they have been mixed with Portland cement to obtain pozzolanic cements respectively with 20%, 30%, 35% and 40% of addition of volcanic tuffs. The pozzolanic reactivity is highlighted by the compressive strength increase until 90 days of conservation in water. It supposes that the vitreous phase of the volcanic tuffs reacts with the free CaO (CaOf) of Portland cement to produce new hydrated minerals. This study has a positive economic and environmental impact. Because the time of grinding of pozzolanic cements is reduced. Also, the addition of volcanic tuffs reduces the production of clinker, then the CO2 emission.

摘要:
A novel method was proposed to design the structure of a bone tissue engineering scafold based on triply periodic minimal surface.In this method,reverse engineering software was used to reconstruct the surface from point cloud data.This method overcomes the limitations of commercially available software packages that prevent them from generating models with complex surfaces used for bone tissue engineering scafolds.Additionally,the fluid feld of the scafolds was simulated through a numerical method based on fnite volume and the cell proliferation performance was evaluated via an in vitro experiment.The cell proliferation and the mass flow evaluated in a bioreactor further verifed the flow feld simulated using computational fluid dynamics.The result of this study illustrates that the pressure value drops rapidly from 0.103 Pa to 0.011 Pa in the y-axis direction and the mass flow is unevenly distributed in the outlets.The mass flow in the side outlets is observed to be approximately 24.3 times higher thanthe bottom.Importantly,although the mean value of wall shear stress is signifcantly more than 0.05 Pa,there is stil a large area with a suitable shear stress below 0.05 Pa where most cells can proliferate well.The result shows that th inlet velocity 0.0075 m/s is suitable for cell proliferation in the scafold.This study provides an insight into the design analysis,and in vitro experiment of a bone tissue engineering scafold.
