AGATE: Unifying Languages and Operating Systems

Noncompliance in antiplatelet trials: the AGATE trial perspective.

Noncompliance in Antiplatelet Trials: The AGATE Trial Perspective To the Editor: Recent studies have highlighted the importance of patient compliance in clinical trials of antiplatelet therapy. The AGATE trial1 was designed as a head-to-head comparison of the antiplatelet properties of Aggrenox (a combination of aspirin and dipyridamole) versus aspirin alone in patients with a recent history of...

Study of agate using the OSL technique and application in

The possibility of using Brazilian stones in gamma high-dose dosimetry was investigated at IPEN using the optically stimulated luminescence (OSL) technique. Agate samples were studied in relation to their OSL dosimetric properties, in this work. The samples were irradiated at a Gamma-Cell system (Co). The calibration curves show a sublinear behavior between 50 Gy and 300 kGy, and the lower dete...

Cost–benefit analysis of installing dust control devices in the agate industry, Khambhat (Gujarat)

It is well known that an exposure to crystalline silica gives rise to silicosis and silico-tuberculosis (TB). In the agate industry of Khambhat (Gujarat) not only workers but also people staying in the vicinity of the agate-grinding facilities are exposed to crystalline silica. To reduce their dust exposure, dust control devices were developed. There are approximately 500 grinding machines loca...

Evolving eyes.

Despite the incredible diversity among extant eyes, laws of physics constrain how light can be collected resulting in only eight known optical systems in animal eyes. Surprisingly, all animal eyes share a common molecular strategy using opsin for catching photons, but there are a diverse collection of mechanisms with proteins unrelated to each other used to focus light for vision. However, opsi...
