AIM The purpose of this study was to investigate the effect of light-emitting diode (LED) light curing units (LCUs) compared with halogen LCUs on the shear bond strength (SBS) of one nanofill composite (Filtek Supreme) and one microhibrid composite (Artemis) with self-etch adhesives. METHODS AND MATERIALS The buccal surfaces of 60 non-carious extracted human molars were flattened to expose de...
Light plays a key role in the development, production performance, health, and well-being of poultry. Yet there are no standards regarding light type, spectrum, intensity and diurnal photoperiod for poultry production. Thus, it is of socio-economic as well as scientific values to assess light needs of pullets and laying hens, especially considering the emergence of LED lights intended for poult...
Recently, BEMS(Building Energy Management System) are emerging in the field of energy savings. Energy management approaches for Unmanned Building often become unreliable in complex building controls due to False detection, lighting changes, and other factors. We present a new framework to robustly and efficiently to detect people staying and going out based on background subtraction and foregro...
Spotlighting is one illumination field where the application of light emitting diodes (LED) creates many advantages. Commonly, the system for spot lights consists of a LED light engine and collimating secondary optics. Through angular or spatial separated emitted light from the source and imaging optical elements, a non uniform far field appears with colored rings, dots or patterns. Many feasib...
In this study, we determined the effects of raising seedlings with different light spectra such as with blue, red, and blue + red light-emitting diode (LED) lights on seedling quality and yield of red leaf lettuce plants. The light treatments we used were applied for a period of 1 week and consisted of 100 mmol m s of blue light, simultaneous irradiation with 50 mmol m s of blue light and 50 mm...
By the example of sp-bonded semiconductors, we illustrate what 3rd-generation muffintin orbitals (MTOs) are. We demonstrate that they can be downfolded to smaller and smaller basis sets: spd, sp, and bond orbitals. For isolated bands, it is possible to generate Wannier functions a priori. Also for bands, which overlap other bands, Wannierlike MTOs can be generated a priori. Hence, MTOs have a u...
Biofuel production from renewable sources is widely considered to be one of the most sustainable alternatives to petroleum sourced fuels and a viable means for environmental and economic sustainability. Microalgae are currently being promoted as an ideal third generation biofuel feedstock because of their rapid growth rate, CO2 fixation ability and high production capacity of lipids; they also ...
Background: Experts and scholars of higher education believe that entrepreneurship is the condition for the survival and development of universities. Therefore, the purpose of the present study was to recognize the influential factors and design a model in order to transform Mashhad University of Medical Sciences into a third generation university. Methods:</stron...
This paper examines the development of adaptive hypermedia systems and proposes adaptive characteristics for third generation adaptive hypermedia systems. First generation adaptive hypermedia systems predated the World-Wide Web (WWW) and were primarily single user adaptive hypermedia systems. Second generation systems have exploited the distributed nature and ease of authoring of the WWW to dev...
