One of the possibilities to mass-produce dye-sensitized solar cell (DSSC) device is if it could be embedded to the area atop metal roof. However, the use of metal substrate is constrained by the corrosion caused by the electrolyte solution used in the DSSC device such as iodide/tri-iodide (I-/I3-). In this study, we propose the utilization of polyaniline/reduced graphene o...

COMPARISON OF ATTENUATION CHARACTERISTICS OF THE ACOUSTIC REFLEX AND THE V-5IR EARPLUG OBJECT To compare the attenuation characteristics of the acoustic reflex and the V-5IR earplug, RESULTS Pre-and post-exposure thresholds were obtained for 13 subjects exposed under two conditions to 100 rounds of machine gun fire (fired one round at a time). In condition I the acoustic reflex (AR) was activat...

Surge protective device is a part of internal lightning protection and it crucially to divert the certain amount of surges to the ground before the protected load able to handle. Therefore, this paper studying the enhancement of SPD through the effect of adding a filter in hybrid surge protection circuit using simulation modeling. Ordinarily, filter is used as in eliminating noises in certain a...

The increasing use of electronics in residential applications has been paralleled by a realization that surge protection may be necessary for this type of equipment. Installing a surge-protective device on the power-line port as well as on the communications-line port of an equipment might appear sufficient to ensure this protection. However, the normal operation of one of the protective device...

As one of the solution of the increase problem of the fault current in a power system, the superconducting fault current limiter (SFCL) has been noticed as the attractive device because it has no power loss in a normal time and can limit the fault current rapidly without additional device to detect the fault current. However, the introduction of the SFCL in a power distribution system affects t...

Intensive potato production technology provides for improving the process of planting tubers with a planter simultaneous treatment protective and stimulating liquids. To this end, design device was developed, parameters pneumatic slot sprayers recommended treated working fluids were optimized.

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...
