The twenty-first century can be described as a challenging time to become media and technologically literate. Insufficient information has the effect of ruining lives, we all have responsibility fight it where see it. Research mostly concentrated on “bright side” technology, aiming understand support in leveraging multiple possibilities afforded its usage. As main channel communication for worl...

Gamma-ray bursts categorically produce broadband afterglow emission, but in some cases, emission the optical band is dimmer than expected based on contemporaneously observed X-ray flux. This phenomenon, aptly dubbed "optical darkness", has been studied extensively long GRBs (associated with explosive deaths of massive stars), possible explanations ranging from host environment extinction to hig...

Geographical conditions Indonesia has natural resources with good potential for the development of renewable energy. One them is wind, wind one in that can be utilized because an archipelagic country a coastline 81000 km. The largest energy are located at sea and near coast. This resource used to generate electricity using turbine, so this research prototype simulate power plant (PLTB). was tes...

The properties and the evolution of asymptotic giant branch (AGB) stars are strongly influenced by their mass loss through a stellar wind. This is believed to be caused radiation pressure due absorption scattering dust grains formed in atmosphere. optical often estimated using small particle limit (SPL) approximation, it has been used frequently modelling AGB winds when performing radiation-hyd...

Geminiviruses cause curly top disease, in dicotyledonous plants which constrains host crop production. Beet curly top Iran virus (BCTIV) is a widespread Becurtovirus (family Geminiviridae) in numerous areas within Iran. In this study, we isolated and analyzed a full-length genomic DNA of a new variant of BCTIV from pepper crops in the Kaftark region, east of Shiraz (proposed acronym: BCTIV-Kaf ...

The complaints, worries and dissatisfactions accrued to bulb users prompted the quest of this research. objective research is suitably assess few electrical parameters bulbs available in market order have an experimental proof disparity their ratings. In data, incandescent (100W 200W), LED (5W) CFL (40W) (of different powers) were selected for evaluation. power lux measured compared correspondi...

ABSTRACT The discs of active galactic nuclei (AGNs) have emerged as rich environments for the production and capture stars compact objects that they leave behind. These produce long gamma-ray bursts (GRBs) at their deaths, while frequent interactions among form binary neutron star–black hole binaries, leading to short GRBs upon merger. Predicting properties these transients emerge from dense AG...

This article presents a new method for effective detection of ac series arc fault (AF) (SAF) and extraction SAF characteristics in residential buildings, which addresses the challenges with conventional current methods discriminating arcing nonarcing due to their similarity. Different from traditional method, proposed differential magnetic flux is coupled obtain high-frequency signals by puttin...

Dye-sensitized solar cells (DSCs)as photovoltaics have been subject of intensive research in the last two decades owing to their outstanding features relative thermal stability, low cost, optical tunability, ability operate under conditions poor lighting, and environment friendliness as such, they offer a promising substitute for conventional monocrystalline silicon cells. Their output efficien...
