18/12/2000· (A) Schematic of a diffusion immunoassay (DIA) implemented in the simplest possible T-sensor. Reagents are pumped separately through device inlets and meet at the junction. At this point, under laminar flow conditions, reagents flow side by side and mix only by

Environmental monitoring - Wikipedia

Environmental monitoring describes the processes and activities that need to take place to characterize and monitor the quality of the environment. Environmental monitoring is used in the preparation of environmental impact assessments , as well as in many circumstances in which human activities carry a risk of harmful effects on the natural environment .

METER Environment | METER

ZENTRA Cloud and the ZL6 data logger work together to simplify your ability to visualize, manage, and share measurements from up to six different types of sensors. With METER’s multi-parameter sensors, you can potentially visualize dozens of different near-real

Lighting Assessment in the Workplace

The light sensor of the luxmeter should be placed on the work plane. Major Task Area For example, if the task position is mostly at the central front area of an ordinary writing desk or a counter (as shown in the following figure), this area may be divided into 4

Directed diffusion for wireless sensor netwong

This enables diffusion to achieve energy savings by selecting empirically good paths and by caching and processing data in-network (e.g., data aggregation). We explore and evaluate the use of directed diffusion for a simple remote-surveillance sensor network

Four Things That Affect Rate of Diffusion | Sciencing

In diffusion, atoms tend to spread themselves evenly, as when the smoke moves from the high concentration in the kitchen to a lower concentration all through your home. The diffusion rate depends on several factors.

Diffusion - Wikipedia

Diffusion is net movement of anything (for example, atom, ions, molecules) from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. For example, if you spray perfume at one end of a room eventually the gas particles will be all over the room The concept of
