ASCORBIC acid has been found to have a marked inhibitory effect on urease activity. With some preparations of the enzyme, the formation of ammonia from urea is completely inhibited by a concentration ...

I dag er der målt 41,7 grader i den tyske delstat Brandenburg. Dermed er varmerekorden fra i går allerede blevet slået. Det oplyser den tyske vejrtjeneste DWD ifølge Ritzau. De 41,7 grader er det ...

Helt usædvanlig varm luft fra Mellemeuropa strømmede lørdag op over Danmark og gav os med 37,0 grader den varmeste dag i dansk vejrhistorie, som nu er tilføjet et kapitel, hvor den 27. juni 2026 står ...

Vejrrekorder fortsætter med at blive slået i Europa, og de tårnhøje temperaturer begynder også at ramme lande helt tæt på Danmark, mens hedebølgen bevæger sig østpå. I Tyskland har man fredag ...

Carbonic anhydrases (CAs) are widespread enzymes in bacteria, archaea and eukaryotes, and catalyze a crucially important physiological reaction: the hydration of carbon dioxide to bicarbonate and ...

Abstract: A fiber-optic urea sensor based on surface plasmon resonance (SPR) and Mach-Zehnder interference (MZI) combined principle was designed and implemented. By plating gold film on the ...

Briterne og tyskerne oplever fredag rekordhøje temperaturer under en europæisk hedebølge. Vejrrekorder fortsætter med at blive slået i Europa, og de tårnhøje temperaturer begynder også at ramme lande ...

This paper estimates that the macroeconomic damages from climate change are an order of magnitude larger than previously thought. Exploiting natural global temperature variability, we find that 1°C ...

Abstract: A potentiometric urea biosensor is prepared by the immobilization of urease directly onto the surface of a solid-state ammonium ion-selective electrode. The enzyme is immobilized by ...

The agricultural industry widely uses urea, a white crystalline solid containing 46 percent nitrogen, as an animal feed additive and fertilizer. Here, we’ll focus on its role as a nitrogen fertilizer.
