Dirty electricity is a ubiquitous pollutant. It flows along wires and radiates from them and involves both extremely low frequency electromagnetic fields and radio frequency radiation. Until recently, dirty electricity has been largely ignored by the scientific community. Recent inventions of metering and filter equipment provide scientists with the tools to measure and reduce dirty electricity...

In this research work, a multibeam antenna which is a combination of a beamformer network (BFN) and a linear array antenna, has been designed. A Rotman lens has been chosen as beamformer network and Vivaldi antennas have been selected for constructing array antenna. The Substrate Integrated Waveguide (SIW) was used for implementing Rotman lens. After explanation the structure of Substrate integ...

Abstract Shapiro ( Quarterly Journal of Economics , 2021) conducts an in‐depth empirical analysis to show that dirtier upstream goods face lower import tariffs than cleaner downstream goods. Inspired by paper, we examine how the welfare maximizing on final will differ depending dirtiness and extent cross border pollution. We countries concerned about controlling pollution but own would be encou...

Most embedded systems are equipped with flash memory owing to its shock resistance, fast access, and low power consumption. However, some of its distinguishing characteristics, including out-of-place updates, an asymmetric read/write/erase speed, and a limited number of write/erase cycles, make it necessary to reconsider the existing system designs to explore its performance potential. For exam...

BACKGROUND:Avian intestinal spirochetosis (AIS) is causedby spiral-shaped Gram-negative Brachyspira spp. in poultry. It isknown as a cause of diarrhea, low egg production, and increasedoccurrence of dirty eggs in layer hens. OBJECTIVES: In this study,the presence of some Brachyspira spp. was investigated in layinghens. METHODS: A total of 100 cloacal swab samples wereindividually collected from...

In the early 1900s in settler colonial states Southern Africa, nascent Jewish community institutions took actions to avoid racialised accusation of dirtiness, thus shaping into adopting white colonialist subjectivities. Using Albert Memmi’s analytic framework colonisers and colonialists, Anne McClintock’s conceptualisation racial function dirt, this article reassesses existing archival sources ...

The epidemics of obesity and diabetes most apparent in recent years had their origins with Thomas Edison's development of distributed electricity in New York City in 1882. His original direct current (DC) generators suffered serious commutator brush arcing which is a major source of high-frequency voltage transients (dirty electricity). From the onset of the electrical grid, electrified populat...
