Due to the continually increasing popularity of metal powder-based additive manufacturing as a production process in recent years, there has been growing research into improving surface quality parts manufactured this way. Laser polishing offers great potential finishing technique due its flexibility and suitability for automation. However, complexity components that can be produced with processes presents challenges developing practical flexible arrangements implementing laser process. In...

Artificial dens constructed for eastern woodrats (Neotoma floridana) were occupied readily by animals, and thus, their caches available repeated sampling over winter. Caches contained significantly fewer kilocalories in spring than winter (X̄ ± SE, = 6,808.6 637.08 kcal, 2,556.8 319.12 kcal). Male female using artificial did not differ weight or the spring. Additionally, change from autumn to spring, weights of individual correlated with caches. Of 17 different types food found dens, seven...

-Adult and juvenile eastern woodrats (Neotoma floridana) were given a choice between uninfected apple at three (first trial) two (second different levels of fungal infection. During the first trial, preferred highly infected over medium second same continued to prefer consume apples intermediate This preference was primarily consequence large amounts consumed by woodrats. Adult nearly equal all groups. Results this study suggest that vertebrates can do biologically important fungally food,...

In recent years additive manufacturing (AM) has been a subject of increased interest and development as it offers many advantages over traditional subtractive machining techniques. As-built surface quality however is rarely suited to the desired application in majority cases (e.g. medical implants), requires post processing.Two main finishing methods are currently used if high level finish required: electrochemical polishing mechanical (abrasive) polishing. The former not selective, latter...
