A dual-band printed dipole antenna with integrated balun feed is given in this paper. First, the fork-shaped slot is etched on the arms of the printed dipole antenna to achieve the dual-band operation with resonances at WLAN bands. The radiating element without balun is optimized and operates at 2.4 GHz (2180–2750MHz) and 5.2GHz (5040 MHz–5480MHz) where return loss is less than −10 dB. In order...

Cocoa production is one of the leading causes deforestation in West Africa. Agroforestry cocoa systems are increasingly promoted as a possible solution to deforestation. This study seeks understand trade-offs within agroforestry full-sun and high-tech plantation Ghana. It uses secondary data collected from an extensive literature search. The results established various between yields other prov...

ABSTRACT Seed germination events modulate microbial community composition, which ultimately influences seed-to-seedling growth performance. Here, we evaluate the germinated maize (variety SHS 5050) root bacterial of disinfected seed (DS) and non-disinfected (NDS). Using a gnotobiotic system, sodium hypochlorite (1.25%; 30 min)-treated seeds showed reduction population size an apparent increase ...

We performed deep observations to search for radio pulsations in the directions of 375 unassociated Fermi Large Area Telescope (LAT) gamma-ray sources using Giant Metrewave Radio (GMRT) at 322 and 607 MHz. In this paper we report discovery three millisecond pulsars (MSPs), PSR J0248+4230, J1207$-$5050 J1536$-$4948. conducted follow up timing around 5 years with GMRT derived phase coherent model...

As part of an All-Sky Automated Survey for SuperNovae (ASAS-SN) search sources with large flux decrements, we discovered a transient where the quiescent, stellar source, ASASSN-V J192114.84+624950.8, rapidly decreased in by $\sim55\%$ ($\sim0.9$ mag) g-band. The \textit{TESS} light curve revealed that source is highly eccentric, eclipsing binary. Fits to using \textsc{phoebe} find binary orbit ...

Abstract The global film industry is shaped by gender inequality. Women are structurally underrepresented in professional roles that include high levels of creative and economic decision-making power, such as directors, writers, producers. In our study, we ask to what extent the festival sector, a prestigious sub-field industry, structured biases. To address this question, conceptualize sector ...
