Simultaneous measurement of temperature and pressure sensor for oceanography using Bragg gratings

A method enabling simultaneous pressure and temperature measurement using a single piezoresistive MEMS pressure sensor

“…A method enabling simultaneous pressure and temperature measurement using a single piezoresistive MEMS pressure sensor Miloš Frantlović 1,2 , Ivana Jokić 2 , Žarko Lazić 2 , Milče Smiljanić 2 , Marko Obradov 2 , Branko Vukelić 2 , Zoran Jakšić 2 and Srđan Stanković 1 [6]. The use of silicon as piezoresistive material results in as much as two orders of magnitude higher sensitivity compared to sensor structures made of metal.…”

“…The measurement method presented in this paper uti lizes the parasitic temperature sensitivity of a silicon MEMS piezoresistive pressure sensing element for both pressure measurement correction and temperature measurement, thus enabling simultaneous highperformance pressure and temper ature measurements using the same sensing element. Some methods for simultaneous pressure and temperature sensing were reported before [1][2][3][4], but for sensors based on different principles of operation. To the best of the authors' knowledge, a method similar to the one presented in this paper has not been described in the literature.…”

“…A vast variety of pressure and temperature sensors exist today, from simple passive sensors and probes to complex computerized devices, systems and sensor networks. Although there is a need for simultaneous pres sure and temperature measurement in industrial processes and other practical situations [1,2], such functionality is typically achieved by using separate sensors and/or sensing elements. Industrialgrade sensing elements capable of simultaneous pressure and temper ature measurement are rare, and so are the reports on the same topic in the literature [1][2][3][4].…”

Activity of metabolic enzymes in farmed rainbow trout Oncorhynchus mykiss Walb. Affected by bacterial septicemia: the effect of feed additives

“…определяли активность ферментов цитохром с оксидазы (ЦО), лактатдегидрогеназы (ЛДГ), глюкозо-6-фосфатдегидрогеназы (Г6ФДГ) и альдолазы в органах особей, выращиваемых на стандартном и обогащённом добавкой рационе. По активности ключевых ферментов аэробного и анаэробного синтеза АТФ, путей окисления глюкозы можно судить об энергетическом статусе и функциональной активности органов рыб: ЦО -показатель уровня аэробного обмена, ЛДГ -анаэробного гликолиза [4]; альдолаза характеризует степень использования углеводов в гликолизе [5]; Г6ФДГ -ключевой фермент пентозофосфатного пути (ПФП) [6].…”

“…Так, нашими коллегами отмечена высокая активность глутатион-S-трансферазы, фермента антиоксидантной системы, у особей из опытной группы [10]. Имеются данные о повышении активности Г6ФДГ и ЛДГ в печени карпа при бактериальной инфекции, вызванной Aeromonas hydrophila [6].…”
