These issues have been aggravatedby the current geopolitical chaos and climatechange. Nevertheless, the continent is projectedto grow at a steady rate of 4.3 percent in 2025.This means that Africa will retain its positionas the fastest-growing region after Asia. This isdriven by several positive factors.展开更多

Interaction between Earth's tectonic plates created the continents and oceans that characterise our planet, while forming the mineral and other resources that support our living lives in modern society. Active tectonic processes are also responsible for devastating hazards such as earthquakes and volcanic eruptions, and control Earth's surface topography which fundamentally affects the climate and environment.

The principle of fluid mechanics stipulates that water yields pressure everywhere in the container that holds it, and the water pressure against the wall of container generates force. Ocean basins are naturally gigantic containers of water, in which continents form the walls of the containers. In this study, we present that the ocean water pressure against the walls of continents generates enormous force, and determine the distribution of this force around continents and estimate its amplitude to be of the order of 1017 N per kilometer of continent width. Our modelling suggests that the stresses yielded by this force are mostly concentrated on the upper part of the continental crust, and their magnitudes reach up to 2.0 - 6.0 MPa. Our results suggest that the force may have significantly impacted the dynamics of continent (lithospheric plate) and its evolution.展开更多

文摘This study investigates the dominant modes of interannual variability of snowfall frequency over the Eurasian continent during autumn and winter,and explores the underlying physical mechanisms.The first EOF mode(EOF1)of snowfall frequency during autumn is mainly characterized by positive anomalies over the Central Siberian Plateau(CSP)and Europe,with opposite anomalies over Central Asia(CA).EOF1 during winter is characterized by positive anomalies in Siberia and negative anomalies in Europe and East Asia(EA).During autumn,EOF1 is associated with the anomalous sea ice in the Kara–Laptev seas(KLS)and sea surface temperature(SST)over the North Atlantic.Increased sea ice in the KLS may cause an increase in the meridional air temperature gradient,resulting in increased synoptic-scale wave activity,thereby inducing increased snowfall frequency over Europe and the CSP.Anomalous increases of both sea ice in the KLS and SST in the North Atlantic may stimulate downstream propagation of Rossby waves and induce an anomalous high in CA corresponding to decreased snowfall frequency.In contrast,EOF1 is mainly affected by the anomalous atmospheric circulation during winter.In the positive phase of the North Atlantic Oscillation(NAO),an anomalous deep cold low(warm high)occurs over Siberia(Europe)leading to increased(decreased)snowfall frequency over Siberia(Europe).The synoptic-scale wave activity excited by the positive NAO can induce downstream Rossby wave propagation and contribute to an anomalous high and descending motion over EA,which may inhibit snowfall.The NAO in winter may be modulated by the Indian Ocean dipole and sea ice in the Barents-Kara-Laptev Seas in autumn.
文摘Objective: Radical cystectomy(RC)is a standard treatment for localized muscle invasive bladder cancer and high-risk or very high-risk non-muscle invasive bladder cancer not responding to adequate endovesical therapy.In women,traditionally RC is performed with hystero-adnexectomy and resection of the anterior vaginal wall,often resulting in sexual disorders.Vaginal-sparing techniques have been developed to improve functional outcomes.The present study explores the safety and the functional outcome of vaginal-sparing techniques.Methods: We retrospectively analyzed all consecutive female patients undergoing robot-assisted RC(RARC)with neobladder diversion between October 2017 and February 2022.The indications for vaginal-sparing RC were absence of tumor on bladder neck or urethra and no sign of infiltration of posterior bladder wall at the preoperative MRI.Functional results were evaluated with the aid of five questions out of the Bladder Cancer Index questionnaire.Complications were reported according to the Clavien–Dindo classification and cancer control was evaluated by recurrence-free and cancer-specific survival.Results: A total of 22 female patients underwent RARC with neobladder diversion.Neoadjuvant chemotherapy was given in 17(77%)cases.Clavien–Dindo grades III–IV complications occurred in four(18%)cases.After a mean follow-up of 29(interquartile range 16–44)months,six(27.3%)patients developed distant metastases,and one(4.5%)woman loco-regional relapse.Sexual-sparing surgery was performed in 19(86%)patients,and in the others the anterior vaginal wall was resected,but neobladder was still performed.During daytime,no patients reported total incontinence and 73%(11/15)reported total continence or only occasional leaks.Sexual results showed that seven of 15(47%)women regained sexual activity after surgery,with a quality reported as“good”or“very good”in 40%of all 19 cases.Conclusion: RARC in female with anterior vaginal wall preservation is feasible.The approach showed a good safety profile,with satisfying results on continence and sexual activity.Sexual-sparing approaches should be carried out after correct patient selection.
文摘The idea of the hypothetical Magellanica Continent(Terra Australis Incognita)was introduced into China by the Jesuit missionaries during the seventeenth century.While not accepted by the Chinese government,it was affirmed and transmitted to the public by a few Chinese scholars,including Feng Yingjing,Cheng Bai'er,Zhang Huang,Xiong Mingyu,Xiong Renlin,You Yi,Zhou Yuqi,Jie Xuan,Wang Honghan,and Ye Zipei.Most of them communicated closely with the Jesuit missionaries,and several even helped the missionaries compose the maps.The concept was updated progressively by Matteo Ricci,Giulio Aleni,Johann Adam Schall von Bell,Francesco Sambiasi,and Ferdinand Verbiest.Chinese scholars copied the missionaries'relevant maps and textual introductions without much modification.However,they paid little attention to advancements in the idea,and many of them circulated outdated knowledge.It was not until the middle-and late-nineteenth century that Chinese scholars reexamined the correctness of this hypothetical continent.
文摘Around 71% of the Earth’s surface is covered by oceans with depths that exceed several kilometers, while continents are geographically enclosed by these vast bodies of water. The principle of fluid mechanics stipulates that water yields pressure everywhere in the container that holds it, and the water pressure against the wall of container generates force. Ocean basins are naturally gigantic containers of water, in which continents form the walls of the containers. In this study, we present that the ocean water pressure against the walls of continents generates enormous force, and determine the distribution of this force around continents and estimate its amplitude to be of the order of 1017 N per kilometer of continent width. Our modelling suggests that the stresses yielded by this force are mostly concentrated on the upper part of the continental crust, and their magnitudes reach up to 2.0 - 6.0 MPa. Our results suggest that the force may have significantly impacted the dynamics of continent (lithospheric plate) and its evolution.
文摘This book delves into an emerging trend in international student mobility specifically focusing on students from across the African continent enrolled in degree programmes at Chinese universities.While China stands out as a highly sought-after destination for African students,there has been limited research to date on this growing mobility pattern.
