How to Conduct Security Studies with Software Developers
Danilova, Anastasia (2022-07-13)As our everyday life depends on software and its security, studies with software developers become ever more important. Motivated by multiple security breaches caused by issues during software development, more studies ... -
How to control cyclic nucleotide signaling by light
Jansen, Vera; Jikeli, Jan F.; Wachten, Dagmar (2017-03-10)Optogenetics allows to non-invasively manipulate cellular functions with spatio-temporal precision by combining genetic engineering with the control of protein function by light. Since the discovery of channelrhodopsin has ... -
How to develop Knowledge and Skills for Mechanization in Africa: Historical examples from the United States and Germany
Daum, Thomas; Huffman, Wallace E.; Birner, Regina (2018-01)Agricultural mechanization is now high on the policy agenda of many African countries, yet few of these efforts emphasize the development of knowledge and skills. However, without the appropriate knowledge and skills, using ... -
How to engage smallholder producers in scaling the dairy and poultry sectors: Lessons from India
Konok, Khadeja Akter; Gulati, Ashok; Ritika, Juneja (2024-02)India is a land of smallholders and its dairy and poultry sectors are no exception. The average herd size of the dairy sector is less than four animals per household. Nevertheless, India is the largest milk producer in the ... -
How to keep tractors running in Africa?: Lessons for knowledge and skills development from Zambia
Thoelen, Jan; Daum, Thomas (2019-02)Successful agricultural mechanization requires building knowledge and skills of machinery owners, operators and technicians on how to manage, run, maintain and repair machinery. Building such knowledge and skills still ... -
