Soil Erosion, the Quiet Crisis : Soil Erosion Problems and Soil Conservation Measures

open access: yes, 2013
現在世界の各地で土壌侵食によって膨大な量の養分を豊かに含んだ表土が流亡し表層を失った土壌の肥沃度が劣化し,農作物の生産量を減少させ続け,深刻な飢餓をもたらす食糧の不足を加速させている。土壌侵食そのものは自然の営みであって,地表で起こる風化生成物の移動であるが,世界各地特に熱帯・亜熱帯の森林または森林跡地で進行中の土壌侵食は,自然の土壌形成速度をはるかに上回る速さで進行し大きな問題となっている。土壌侵食は表土の流亡を加速化し土地生産力を急速に低下させるとともに,土地の環境保全機能を著しく低下させる ...

‘It's all very well having a diverse curriculum, but if there is no curriculum, it can be as diverse as you like’: Precarity and decolonising in the neoliberal UK higher education system

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Drawing upon interview research across two academic departments as part of the early stages of a ‘decolonise the curriculum’ initiative at a Southern UK university, this study highlights a growing gulf between policy and practice in efforts to address systemic racial inequalities in UK universities. A reliance upon precarious labour, a culture

Magnetoelastic Cell Monitoring System for Evaluating the Effects of Surface Chemistry on the Performance of Mesenchymal Stem Cell Growth

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The recent clinical adoption of cell therapies has increased the need for more efficient, robust, and reproducible manufacturing technologies. Human mesenchymal stromal cells (hMSCs), a major component of the cell and immunotherapeutic market, remain challenging to manufacture at scale because they require surface attachment and are highly ...
