2. Retinoids and vitamin D in skin and parathyroid glands
Abstract : Vitamin D3 (VitD3) and retinoids are important factors involved in differentiation and proliferation in many cell systems. Their effects in skin, where retinoids and vitamin D are known to be crucially involved in keratinocyte differentiation and function,, and in the parathyroid, the overall regulatory organ in calcium homeostasis were studied.

3. Electro-thermal simulations and measurements of silicon carbide power transistors
Abstract : The temperature dependent electrical characteristics of silicon carbide power transistors – 4H-SiC metal semiconductor field-effect transistors (MESFETs) and 4H-SiC bipolar junction transistors (BJTs) have been investigated through simulation and experimental approaches. Junction temperatures and temperature distributions in devices under large power densities have been estimated. READ MORE
