A review of soil fertility management communication in sub-Saharan Afrika
(2021-02-12)
In sub-Saharan Africa (SSA), declining soil fertility is among the factors a ecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socioeconomic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM ...

Investigation of potential drying strategies for quality maintenance of carrot
(2021-05-27)
Convective drying of carrots is a non-linear and unsteady-state process with simultaneous mechanism of heat and mass transfer leading to time varying quality changes along the process and finally causing irreversible quality modification. Inappropriate drying condition will generate many qualities related problems such as destruction of physical properties and discoloration of carrots causing by mechanical and thermal damage due to over-drying or extended drying periods. Inconsistent quality of the product was also ...

Stadtklimaanalyse light
(2021-08)
Aufgrund des Klimawandels und den damit verbundenen wachsenden Anforderungen an Städte muss in Zukunft ein genauer Blick auf die Grün- und Freiflächen von Städten geworfen werden. Die Analyse und Bewertung von stadtklimatischen Verhältnissen innerhalb einer Stadt ist dabei jedoch besonders herausfordernd. Hinzu kommt, dass Stadtklimaanalysen teuer sind und daher nicht zum Monitoring und zur Evaluation von Maßnahmen eingesetzt werden können. Daher ist ein auf offenen Daten basiertes GIS-Tool in Zukunft wichtig, um ...

Quantification of the In Vitro Predisposition to Glistening Formation in One Manufacturer’s Acrylic Intraocular Lenses Made in Different Decades
(2021-02-05)
Introduction
Foldable hydrophobic acrylic intraocular lenses (IOLs) are prone to develop a long-term postoperative material change called glistenings. The aim of this study was to investigate the changes in the predisposition for glistening formation in one type of hydrophobic acrylic IOL material from its introduction to the present day.
Methods
In a laboratory setup, an in vitro model was used to induce glistenings in hydrophobic acrylic IOLs manufactured by one company (Alcon, Fort Worth, TX, USA) in different ...
