objective: traditional methods for storing microbial dna samples use the low-temperatures of 4 °c, -20°c or -80 °c. the dbc card is a new method of storing microbial dna at room temperature. this study evaluates the stability and determine the best storing method of bacterial dna on the dbc card. methods: in this study, we used a pair of primers from the conserved domain of 16srrna designed to...

A heuristic algorithm is proposed for dynamic calculation qf the median and other quantiles. The estimates are produced dynamically as the observations are generated. The observations are not stored; therefore, the algorithm has a very small and fixed storage requirement regardless of the number of observations. This makes it ideal for implementing in a quantile chip that can be used in industr...

Summary Some molecular photoisomers can be isomerized to a metastable high-energy state by exposure light. These molecules then thermally or catalytically converted back their initial state, releasing heat in the process. Such reversible photochemical process has been considered for developing solar thermal (MOST) systems. In this review, we introduce concept, criteria, and state-of-th...
