Disperse dye inks are used in the inkjet textile printing of polyester fabrics. We aimed at developing a black disperse dye ink consisting of yellow, magenta, and cyan dyes that met the exacting requirements of safety, image durability, and storage stability. One difficulty we met was dye particles tending to aggregate/agglomerate, leading to sedimentation and the threat of head clogging and/or...

Once, Europe was one large natural area, across which species of animals and plants were able freely to move and disperse. Today, a satellite image of Europe looks like a Persian carpet cut into millions of small rectangular pieces, each fashioned by the plough and the spade over thousands of years of cultivation. The consequence of this change is that species have disappeared. For example, ani...

Radiological terrorism (radioterrorism) is the deliberate use of radiological weapons. These weapons use radioactive materials to disperse and emit ionizing radiation. There are two classes of radiological weapons - radiological dispersal devices (RDD) and radiation emission devices (RED). These weapons would no cause massive numbers of dead. In most radiological attack scenarios, only few peop...

In energy constrained Wireless Sensor Networks (WSN), network lifetime is considered as one of the most important metrics from the design point of view. In our paper, we have addressed the impact of a disperse node on network lifetime and have proposed a new design approach, Lifetime Enhancement for Disperse Networks (LEDN) to reduce its effect on a two tiered WSN. A mathematical analysis has a...

Thirty-one blood samples were obtained from wild male black bears at different times of the calendar year. The samples were assayed for serum testosterone and the results were correlated with testicular size, time of year and nutritional status. A significant annual testosterone rhythm was found with high values during March through mid-July (mean 153 ng per 100 ml) and low values from mid-July...
