V. An Inexpensive Water Motor

an iranian simple, inexpensive and programmable motor – driven treadmill for exercising small laboratory rodents

nowadays, research on exercise physiology has developed. many of studies try to discover body responses or adaptations to exercise training or physical activity. in many cases, human beings are not suitable models to study these mechanisms in vivo due to ethical and legal limitations. laboratory animals especially mice and rats are appropriate models for these researches. treadmill is an excell...

An inexpensive blackbody model

A blackbody is a fundamental concept in thermography. A perfect model of blackbody is characterized by emissivity =1 which is difficult to be obtained. There are black body simulators which are being used for calibration of infrared devices. Commercial solutions of blackbody simulators are based on mathematical models of cavity or surface blackbodies and their emissivity is closer to unity e.g....

An Inexpensive Light Stage Dome

This article describes a process for constructing a real-world 1 m-diameter icosahedral dome frame with equipment mounting points at the vertices. Such frames, called Light Stage domes, are important tools for computer graphics and vision measurements and relighting applications. Typical domes have 2 m diameter and are constructed from bolted steel parts. The new half-size dome is inexpensive, ...

An Inexpensive Suture Practice Board

OBJECTIVE We provide a design for an effective suture practice board for surgical instruction that is both easily assembled and repaired. METHODS This model's design is achieved through inexpensive materials that do not compromise adequate simulation through repetitive use. We used a wooden board, synthetic microfiber cloth, and metal plates and screws to create the suture board. Two pieces o...
