Germany is a most appropriate place for this exploration. Johannes Gutenberg’s western invention of the printing press about 1450 made the Renaissance possible and the printed text both possible and affordable. Martin Luther’s insistence fifty years later that the written word was not a danger to people and that the Bible and other texts should be “unchained” and made available in the vernacula...
The search for ever smaller violations of Einstein’s weak equivalence principle continues to be an important experimental goal at the close of the 20th century, with string theory providing new motivations. Currently, the most sensitive laboratory and terrestrial-scale tests are carried out with instrumentation based on the 18th century concept of the torsion pendulum, but not with 18th century...
Pulsations of the brain were observed and noted since antiquity. Galenic concepts that the brain pulsations propel psychic pneuma to the nerves were challenged during the Renaissance and replaced by other theories. During the age of the Enlightenment, scientists began to study by observation and experiment whether these pulsations were generated by the dura mater, the respiratory movements or t...
This essay is a response to Askegaard and Linnet’s (2011) call for a greater epistemological plurality within consumer culture theory (CCT). The paper begins with a brief review of what these authors refer to as the dominant existential-phenomenological perspective and their Morinian alternative, and then presents contemporary political philosophy as another alternative. Political philosophy ha...
this study focuses on achieving high stiffness/strength and good fr characteristic of nylon 66/mca/nc nanocomposites, prepared via melt compounding by twin screw extruder. a synergistic effect of flame retardant systems based on melamine cyanurate and zinc borate on the flammability and mechanical behaviours of crysnanoclay reinforced nylon 66 nanocomposites have been reported. mechanical test ...
در سال های اخیر زیست فناوری کاربردهای فراوانی در واحدهای تکمیل و رنگرزی صنعت نساجی داشته است. آنزیم ها ترکیب هایی پروتئینی هستند که در بسیاری از واکنش های مورد نیاز در فرایندهای نساجی می توانند شرکت کنند. این تحقیق به منظور اصلاح ویژگی های الیاف نایلون 66 و بررسی ویژگی های متفاوت آن شامل رنگ پذیری، جذب رطوبت، تغییرهای سطحی و ثبات های رنگی با استفاده از آنزیم پروتئاز انجام شده است. بدین منظور من...
