James Alexander Thomson [4], affectionately known as Jamie Thomson [4], is an American developmental biologist whose pioneering work in isolating and culturing non-human primate [5] and human embryonic stem cells [6] has made him one of the most prominent scientists in stem cell research. While growing up in Oak Park, Illinois, Thomson?s rocket-scientist uncle inspired him to pursue science as ...

Two new species of Onciderini are described and illustrated: Oncideres tavakiliani, from Brazil (Pará), and Clavidesmus egeri, from Peru. Oncideres defectiofasciata Gilmour, 1950 is a junior synonym of O. chevrolatii Thomson, 1868. The following four new country records are reported: O. crassicornis Bates, 1865 (Paraguay); O. glebulenta Martins, 1981 (Paraguay); O. gutturator (Fabricius, 1775) ...

manual citrus harvesting is commonly performing hard, expensive and time consuming. in this study, a factorial experiment with a completely randomized design in three replications was performed to find out the effect of frequency (three levels of 5, 7.5 and 10 hz), vibration time (three levels of 10, 15 and 20 seconds) on harvesting capacity and losses of thomson cultivar of orange. the results...

Heat exchangers are the critical components of refrigeration and liquefaction processes. Selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in Joule-Thomson cooling system results in improving the performance and efficiency. In the current study, a straightforward procedure is introduced to design an efficient Joule-Thomson co...
