22 The impact of Bacillus weihenstephanensis KBAB4 sporulation temperature 23 history was assessed on spore heat resistance, germination and outgrowth capacity at a 24 temperature range from 7 to 30°C. Sporulation rate and efficiency decreased at low 25 temperature, as cells sporulated at 12, 20 and 30°C with approximately 99% 26 efficiency, whereas at 7°C and 10°C, a maximum 15% of sporulation...

modeling of drying kinetics of canola was studied at 30 to 100 ?c in a lab scale fluidized bed dryer. drying rate of the crop was assessed, using many conventional moisture ratio models employed in food science. effective diffusivity coefficient (deff) and activation energy (ea) of kernel moisture were determined using fick's law of diffusion and arrhenius equation. besides, the effects of...

to assess the effect of time and temperature (in the pumice mixing phase of olive oil extraction) on the quantity and quality features of the extracted oil, a series of experiments comprised of three levels of mixing time (10, 20, and 30 min), and three levels of mixing temperature (30, 45, and 60°c) were carried out. the recorded data were analyzed in the framework of a randomized complete blo...

Effect of low temperature stress treatment in five selected clones of Camellia sinensis (T-17, TV-19, TV-25, TV-29, TV-30) was found to be significant. Guaiacol Peroxidase (GPX) decreased with decreasing temperature. PPO decreased with decreasing temperature showing highest activities at 20°C in all clones. CAT activit ies decreased in T-17, TV29, and TV-30 with decrease in temperature with exc...

This paper presents an ultra-low embedded power temperature sensor for passive RFID tags. The temperature sensor converts the temperature variation to a PTAT current, which is then transformed into a temperature-controlled frequency. A phase locked loop (PLL)-based sensor interface is employed to directly convert this temperature-controlled frequency into a corresponding digital output without ...

Herein we describe a simple platform for rapid DNA amplification using convection. Capillary convective PCR (CCPCR) heats the bottom of a capillary tube using a dry bath maintained at a fixed temperature of 95°C. The tube is then cooled by the surrounding air, creating a temperature gradient in which a sample can undergo PCR amplification by natural convection through reagent circulation. We de...

A new oxazole-containing proteasome inhibitor, secomycalolide A, together with known mycalolide A and 30-hydroxymycalolide A, was isolated from a marine sponge of the genus Mycale. They showed proteasome inhibitory activities with IC50 values of 11-45 μg/mL.

The structure of the title salt, C(12)H(12)N(+)·HSeO(4) (-), consists of infinite parallel two-dimensional planes built of 4-benzyl-pyridinium and hydrogen selenate ions that are mutually connected by strong O-H⋯O and N-H⋯O hydrogen bonds. There are no contacts other than normal van der Waals inter-actions between the layers.

We investigated six cases of enterovirus infection in a neonatal unit. The index patient, a 5-day-old boy, was admitted with aseptic meningitis due to echovirus 30 (E30). Secondary infections with E30 occurred in five babies. Comparison of the complete VP1 sequences showed that the isolates recovered from the index patient and his mother were closely related to those recovered from the five bab...
