فرضیه: اصلاح شیمیایی کوپلیمرها و پلیمرهای تجاری و صنعتی مانند پلیپروپیلن (PP) یکی از تلاشها و چالشهای دانشمندان پلیمر است. در این کار پژوهشی، نانوکامپوزیت پلیپروپیلن اصلاحشده با پلیاستیرن و نانولوله کربن چنددیواره با روشهای جدید پلیمرشدن شامل پلیمرشدن رادیکالی زنده تهیه شدند. روشها: بدین منظور، ابتدا پلیپروپیلن عاملدارشده با مالئیک انیدرید تهیه شد. سپس برای ایجاد درشتآغازگر، پ...
The evolutionary origin of rhythm perception, a cognitive ability essential to musicality, remains unresolved [1-5]. The ability to perceive and memorize rhythmic sounds is widely shared among humans [6] but seems rare among other mammals [7, 8]. Although the perception of temporal metrical patterns has been found in a few species, this ability has only been demonstrated through behavioral trai...
the purpose of the present study was to investigate the effect of music tempo on heart rate and rate of perceived exertion of male physical education students. to this purpose, 45 male physical education students (height: 172.27 cm, sd=16.22, body mass index (bmi): 22.27kg/m², sd=3.08, weight: 68/05kg, sd=11.73, age: 21.93 years, sd=1.81) were randomly divided into control, high tempo (bpm=140)...
Problematic fermentations are common in the wine industry. Assimilable nitrogen deficiency is the most prevalent cause of sluggish fermentations and can reduce fermentation rates significantly. A lack of nitrogen diminishes a yeast's metabolic activity, as well as the biomass yield, although it has not been clear which of these two interdependent factors is more significant in sluggish fermenta...
Sensorimotor synchronization (SMS) is especially apparent—and therefore readily studied—in musical settings, as most people are naturally able to perceive a musical beat and synchronize to it (e.g. by tapping a finger). SMS processes have been tested extensively using pseudo-musical pacing signals, so we chose to extend this by using naturalistic, expressively timed piano music, characterized b...
This preliminary study investigates the relationship between tempo indications in a score and the tempo performed by musicians. As several 18 century theorists point out, the chosen tempo should depend not only on the tempo indication, but also on other factors such as the time signature and the fastest note values to be played. It is examined whether the four main tempo indications (Adagio, An...
Deficits in bimanual coordination of older adults have been demonstrated to significantly limit their functioning in daily life. As a bimanual sensorimotor task, instrument playing has great potential for motor and cognitive training in advanced age. While the process of matching a person's repetitive movements to auditory rhythmic cueing during instrument playing was documented to involve moto...
Neuroscientists interested in examining higher brain function hope to discover a common neural coding language that subserves complex mental processes (Calvin, 1997; Shaw, 2000). Identifying the structural features of such a neural code is of primary importance to cognitive scientists because it would provide an intermediate-level structure capable of linking cognitive functions to low-level ne...
