The most commonly used method for including photovoltaic system in the control of frequency is to operate a PV power plant at reduced while maintaining specific amount available reserve. Such operating regime, often referred as de-loaded, can cause additional costs and, consequently, determining required reduction becomes vitally important. This paper introduces minimum de-loaded reserve system...

The construction and characterization of a new ion-selective electrode for the determination of the antipsychotic ziprasidone in mixed solvents is presented. The electrode contains a plasticized polymeric membrane based on a ziprasidone-tetraphenylborate ion-exchanger. The influence of membrane composition on the electrode response towards ziprasidone in hydroalcoholic solutions was studied. Th...

Body size determination is a process that is tightly linked with developmental maturation. Ecdysone, an insect maturation hormone, contributes to this process by antagonizing insulin signaling and thereby suppressing juvenile growth. Here, we report that the microRNA miR-8 and its target, u-shaped (USH), a conserved microRNA/target axis that regulates insulin signaling, are critical for ecdyson...
