Although the columella cells of the root cap have been identified as the site of gravity perception, the cellular events that mediate gravity signaling remain poorly understood. To determine if cytoplasmic and/or wall pH mediates the initial stages of root gravitropism, we combined a novel cell wall pH sensor (a cellulose binding domain peptide-Oregon green conjugate) and a cytoplasmic pH senso...

BACKGROUND Bacterial contamination or platelet (PLT) metabolism can change the pH of stored PLT concentrates (PCs). Measurement of pH for quality control is currently done on a limited basis. An easy noninvasive method was developed to obtain sequential pH measurements over time, without risking contamination and/or consuming PCs. STUDY DESIGN AND METHODS The objective was to measure pH profi...

Wearable sensor systems have become promising tools in modern health care. Vital signs are recored to monitor the condition of a subject in a continuous manner. In order to assess sports performance and optimize training, as much as possible information on the athlethes condition is helpful. We present a wearable and disposable sensor that measures heart rate, oxygen saturation, pH value, skin ...

In this study, a high-performance inductively coupled thin film multifunctional sensor for structural monitoring applications is presented. A versatile layer-by-layer self-assembly sensor fabrication technique is employed to encode different sensing mechanisms (e.g. strain and corrosion/pH) within one homogeneous thin film structure. Judicious selection of various polyelectrolyte species, along...

A Wireless Sensor Network (WSN) is emerging field in Information and communication technology. In WSN data transmission and data collection are unsecure because of sensor node Incompatibility. So providing security to Sensor network is very important. The key based Mechanism is secure data collection and it’s mainly used to guarantee data confidentiality. Range pair wise key is largely used due...

-The conservation of milk is of major concern in developing countries like India, due to the lack of supply at many household in rural and Industrial areas. In existing system a collection vehicle is assigned for each group of areas. If the vehicle fails to arrive at a particular destination at correct time the milk gets spoiled and becomes useless. The proposed method eliminates this drawback ...
