In 1895 Wilhelm Conrad Roentgen was the professor and head of the department of physics at the Julius-Maximillan University at Wurzburg in Germany. On the 8 November of that year, he was working with cathode rays using evacuated glass bulbs. Rontgen noted that when a current was passed across the bulb, a barium platinocyanide screen was seen to fluoresce. He at once realised the significance of...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...

Holomorphic dynamics has been a key area of study for 100 years. In this survey, we focus on the dynamics of rational functions.
increasing academic and professional language demands around the world are not a deniable fact. the purpose of this study was to investigate english language needs and communication needs of the chemistry students at master and ph.d. levels at the iranian universities. in this research, different methods were used including un-structured interview, structured interview, and two sets of question...
Poliovirus was first isolated nearly 100 years ago in a landmark experiment that established the viral etiology of poliomyelitis.

This anniversary is a milestone in American psychiatry for "The history of American psychiatry is the history of the American Psychiatric Association, and the tradition of this Association permeates all the pages which are herewith submitted to the reader...
This historical review takes a few selected issues from the rheological studies of extensional flow that fill the literature, starting with extracts from the seminal papers of Trouton (Proc. Roy. Soc. A77 (1906) 426-440) and Fano (Archivio di fisiologio, 5 (1908) 365-370). Work in the first half of the twentieth century on spinnability and extensional viscosity measurement is highlighted, follo...
