A Comparative Discourse Analysis of TRT World and Al Jazeera News Channels on the News Reports of the Syrian War

In the last two decades, we have witnessed the rising of new international news networks such as Al Jazeera, Russian Today, and TRT World in order to challenge the main media corporations of the Western world like, CNN, BBC, and MSNBC, etc. particularly on the news regarding the Middle East. While the results of the Gulf War in 1990 and the invasion of Iraq in 2003 have made checks and balances on Western news associations necessary, Al Jazeera, the Qatar-based broadcaster, emerged as a remarkable voice by taking the role of a contra-flow news agency, and succeeded in producing different and original opinions within its region in the international news arena. In this context, this study selected a critical approach to TRT World, one of the recent news players in the region of the Middle East, in order to identify if it is achievable for the channel to bring a unique perspective on the news regarding the Middle East, as Al Jazeera has accomplished. A critical discourse analysis was conducted by analyzing the news reports of TRT World and Al Jazeera’s stories regarding the Syrian Civil War. However, the study results suggest that TRT World misses the claim of ‘‘new and accurate perspectives ‘to the international arena due to political factors

A Compact Millimeter-Wavelength Fourier-Transform Spectrometer

We have constructed a Fourier-transform spectrometer (FTS) operating between 50 and 330 GHz with minimum volume (355 x260 x64 mm) and weight (13 lbs) while maximizing optical throughput (100 $\mathrm{mm}^2$ sr) and optimizing the spectral resolution (4 GHz). This FTS is designed as a polarizing Martin-Puplett interferometer with unobstructed input and output in which both input polarizations undergo interference. The instrument construction is simple with mirrors milled on the box walls and one motorized stage as the single moving element. We characterize the performance of the FTS, compare the measurements to an optical simulation, and discuss features that relate to details of the FTS design. The simulation is also used to determine the tolerance of optical alignments for the required specifications. We detail the FTS mechanical design and provide the control software as well as the analysis code online.Comment: Submitted to Applied Optics. [Copyright 2019 Optical Society of America].

Effects of live yeast supplementation on ruminal parameters and lactation performance of dairy cows fed medium or high levels of dietary concentrate

The objectives of this study were to determine the effect of live yeast (LY) supplementation and dietary concentrate level interaction on ruminal parameters, dry matter intake (DMI), milk yield, and milk composition of lactating dairy cows. Four multiparous Holstein cows were assigned to one of four dietary treatments in a 4x4 Latin Square design in a 2x2 factorial arrangement with 21-d periods The dietary treatments were:1) 50% concentrate + live yeast (10 g/cow/d; 50LY), 2) 50% concentrate + no live yeast (50NLY), 3) 70% concentrate + live yeast (10 g/cow/d; 70LY), and 4) 70% concentrate + no live yeast (70NLY). A more distinct effect of the LY supplementation on ruminal pH was observed at 9 h of post-feeding, where cows that received 70NLY had the lowest ruminal pH (5.81) compared to cows that received 70LY (6.40; P< 0.05). The LY supplementation decreased the sum of ruminal isobutyrate, isovalerate, and valerate concentrations (4.3 vs. 4.6 mol/100 mol and 4.7 vs. 4.8 mol/100 mol) in both 50 and 70% concentrate diets compared to NLY (P= 0.02). Overall, the LY supplementation had only numerically higher on DMI (18.0 vs. 17.5 kg/d), milk yield (20.2 vs. 19.1 kg/d), and 3.5% fat corrected milk (19.4 vs. 18.8 kg/d) compared to NLY supplementation, respectively. The LY supplementation tended to increase (P= 0.06) milk fat yield in 50LY (0.66 kg/d) compared to 50NLY (0.62 kg/d). Similarly, the LY supplementation tended to increase (P= 0.08) solid non-fat (SNF) percentage in 50LY (9.83%) compared to 50NLY (9.63%). Although there were only numerical increases in DMI, milk yield, and 3.5% fat corrected milk with the supplementation of the LY, results indicated that the LY supplementation in the 50% concentrate diet would increase milk protein, SNF, and lactose percentages. In conclusion, ruminal pH reductions associated with feeding high dietary concentrate (70%) diets in dairy cows can be prevented with the LY supplementation

The Southern Wide-field Gamma-ray Observatory reach for Primordial Black Hole evaporation

The Southern Wide-field Gamma-ray Observatory (SWGO) is a proposed ground-based gamma-ray detector that will be located in the Southern Hemisphere and is currently in its design phase. In this contribution, we will outline the prospects for Galactic science with this Observatory. Particular focus will be given to the detectability of extended sources, such as gamma-ray halos around pulsars; optimisation of the angular resolution to mitigate source confusion between known TeV sources; and studies of the energy resolution and sensitivity required to study the spectral features of PeVatrons at the highest energies. Such a facility will ideally complement contemporaneous observatories in studies of high energy astrophysical processes in our Galaxy

Study of water Cherenkov detector designs for the SWGO experiment

The Southern Wide-field Gamma-ray Observatory (SWGO) is a next-generation ground-based gamma-ray detector under development to reach a full sky coverage together with the current HAWC and LHAASO experiments in the northern hemisphere. It will complement the observation of transient and variable multi-wavelength and multi-messenger phenomena, offering moreover the possibility to access the Galactic Centre. One of the possible SWGO configurations consists of an array of water Cherenkov tanks, with a high fill-factor inner array and a low-density outer array, covering an overall area of one order of magnitude larger than HAWC. To reach a high detection efficiency and discrimination capability between gamma-ray and hadronic air showers, various tank designs were studied. Double-layer tanks with several sizes, shapes and number of photomultiplier tubes have been considered. Single-particle simulations have been performed to study the tank response, using muons, electrons, and gamma-rays with energies typical of extensive air showers particles, entering the tanks with zenith angles from 0 to 60 degrees. The tank response was evaluated considering the particle detection efficiency, the number of photoelectrons produced by the photomultiplier tubes, and the time resolution of the measurement of the first photon. The study allowed to compare the performance of tanks with circular and square base, to understand which design optimizes the performance of the array. The method used in the study and the results will be discussed in this paper
