The present invention relates to novel triazolo4,3-apyridine derivatives of Formula wherein all radicals are as defined in the claims. In one implementation, a plurality of prior queries are selected wherein each of the prior queries was submitted as a search query a number of times during a recent time period and satisfies a criterion. The microfluidic array card reader includes a housing, a receiving section for receiving the microfluidic array card, a viewing section, and a light source that directs light to the array window of the microfluidic array card and to the viewing section. The resulting positioning of the web apex presents a maximum surface area for welding the web to the chord member.
