take place inside of the human body such as the firing of action potentials in neuronal cells in the brain. The research presented in the paper “High-Fidelity optical reporting of neuronal electrical activity with an ultrafast fluorescent voltage sensor” shows just how far brain mapping has come and how far it still has to go before all pathways are truly understood. This paper presents the medical community the opportunity to harness the versatility of Green Fluorescent Protein (GFP) in order…

One of the parameters that determines water quality is pH. It is defined as the negative logarithm of the hydrogen ion and is intended to be a measurement of the balance of acids and bases. Temperature affects pH. In pure water, a decrease in pH of 0.45 occurs when temperature is increased by 25°C [11]. There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of…

methods are spectroscopic methods requiring costly and huge equipments and need proper sampling and storage [10]. They also have their limitations when concentration to be measured is in ppm level .Optical Fiber grating(OFG) sensors may provide a good option as a chemical sensor in determining the concentration of trace elements in drinking water. This method is simple, requires minimum equipments and most important, can be monitored on line so as to check the concentration of the element in…

was KTS 570 which can be connected directly to the car through the OBD port. When the check was run with the help of the ESI tronic the fault was found in the right front wheel speed sensor . wheel speed sensor cannot be serviced so it has to be replaced. Typical problems include loss of sensor signal due to sensor failures or wiring faults, problems in the ABS modulator, pump motor, pump relay or high pressure accumulator. Always check for vehicle manufacturer technical service bulletins any…

ADC outputs a value of 0111 1010, what is the distance measured? 7. Design the basic interface circuit (using an op amp) for a temperature sensor that covers a range of 0° to 70°C if the output of the sensor is 2 mV/1°C and the ADC voltage range is 0 to 4 V. 8. Design an amplifier suitable for converting the output voltage from an LM35 temperature sensor (10 mV/°C) into a signal that makes use of the full input voltage range (0-5V) of the HCS12 ADC port pins. Assume the LM35 is to measure…

changes to the industry and competitive environment. The sensor industry occurred mainly as domination. This did not give the industry much of a market share; the industry recognized that it could not supply distinctive balance to a consumer base for the same reason. As an alternative, they decided to divide the industry into six diminutive businesses. All six-sensor businesses focal points were based on a diverse consumer type. By doing this the sensor industry, market share became more…

different seeds. We know that aerobic respiration requires oxygen gas and an organic molecule, and produces carbon dioxide, water, and energy. The goal of cellular respiration is to harvest ATP. However, the carbon dioxide can be measured using a gas sensor. Since we know that more reactants generally equals more products, more organic molecules should result in more carbon dioxide, thus, increasing the rate of cellular respiration. We can measure the rate of carbon dioxide production to…

by connecting micro structured resistive pressure sensors, flexible printed organic electronic circuits, and nerve cells containing light activated ion channels. The pressure sensors are made out of carbon nanotube-elastomer composite shaped into micro pyramidal structures that are covered on top of a surface. The sensors will respond according to programed pressure. Bao in the past had made very similar capacitive sensors, but these new sensors are better at detecting the range of pressures…

In this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…
