Acceleration of microglial clearance function by small TREM2-activating anionic disaccharides
(2014-07-29)Triggering receptor expressed on myeloid cells-2 (TREM2) is an innate immune receptor, which is expressed on myeloid cells, like microglia inside the central nervous system. TREM2 signals via the adaptor protein DAP12. ... -
Acceptance Analysis of New Technology for Sustainable Water Management and Sanitation: A Case Study of Operating Farm Households in the Mekong Delta, Viet Nam
(2005)Recent development in agricultural und industrial production leads to increasing pollution of the water sources in the Mekong Delta of Vietnam. According to the "Vietnam Environment Monitor 2003 - Water", no safe drinking ... -
Acceptance of innovations for sustainable food production: A consumer and farmer perspective on the use of soil-microbes
(2024-02-05)In alignment with a transition to sustainable agriculture, alternatives for conventional harmful agricultural inputs are needed. Researchers in the field of plant production have emphasised that beneficial soil-microbes ... -
Access and Barriers to Health Care Services in rural Malawi
(2021-02-25)Background: In its Vision 2020, the Malawi Sustainable Development Network Programme (SDNP) acknowledges that lacking access to quality health care services is one of the most serious problems of Malawi's health sector. ... -
Access to and reactions of P-functional tetrathiafulvalene derivatives
(2023-05-09)This Ph.D. thesis describes the chemistry of the first P-functional tetrathiafulvalenes; the chlorophosphanyl-substituted TTFs were subjected to a reaction with Galliumtrichloride, as a chloride abstraction reagent, to ... -
Accountability in the parliament of Malaysia: A study on interruptions by the Chairperson in the Dewan Rakyat
(2021-09-03)The election of the chairman of the House of Representatives, a chamber of the Malaysian parliament, has always been determined by the ruling party. The centralization of executive power has also absorbed the function of ... -
