AbstractA field experiment was implemented during during of crop year 2023-2024 at the Agricultural Engineering Research Station of the University of Baghdad to evaluate the influence of row orientation and planting density on certain growth traits, grain yield, and quality indices of bread wheat cultivars. The experiment was designed as a split-plot arrangement within a randomized complete block design (RCBD) with three replications. The main plots included three wheat cultivars (Iba’a-99, Buhooth-22, and Buhooth-10), while the subplots consisted of three planting densities (80, 100, and 120 kg ha−1), and the sub-sub plots were assigned to two row orientations: East-West and North-South. The results indicated that the Iba-99 cultivar significantly excelled in the number of tillers per meter square (439.14 tiller m−2), flag leaf area (43.45 cm2), number of spikes per meter square (348.31 spike m−2), number of grains per spike (50.03 grain spike−1) and grain yield (5.027 tons ha−1), while the Buhooth-10 cultivar were significantly superior in the gluten content in grains (33.15%). The 120 kg ha−1 planting density was significantly superior in the number of tillers per meter square (433.39 tiller m−2), number of spikes per meter square (347.20 spike m−2) and grain yield (5.207 tons ha−1), whereas the 80 kg ha−1 seeding rate significantly excelled in the number of grains per spike (50.82 grain spike−1) and gluten content in grains (33.26%). The East-West row orientation significantly excelled in the number of tillers per meter square (419.98 tiller m−2), flag leaf area (43.39 cm2), number of spikes per meter square (331.98 spike m−2), number of grains per spike (48.93 grain spike−1), grain yield (4.934 tons ha−1) and gluten content in grains (33.11%). The di and tri-interaction between studied factors hadn’t a significant effects on the most studied traits.

Abstract:

Interest in the topic of prediction has increased in recent years and appeared modern methods such as Artificial Neural Networks models, if these methods are able to learn and adapt self with any model, and does not require assumptions on the nature of the time series. On the other hand, the methods currently used to predict the classic method such as Box-Jenkins may be difficult to diagnose chain and modeling because they assume strict conditions.

Background: Bacteriocin is a peptidic toxin has many advantages to bacteria in their ecological niche and has strong antibacterial activity. Objective: The aim of this study was to evaluation of bacteriocin using Streptococcus sanguinis isolated from human dental caries.

Subjects and Methods: Thirty five streptococcus isolates were diagnosed and tested for their production of bacteriocin, and then the optimal conditions for production of bacteriocin were determined. After that, the purification of bacteriocin was made partially by ammonium sulfate at 95% saturation levels, followed by and gel filtration chromatography

The Kurds' positions were characterized by insistence on their rights during the monarchy and choosing various solutions to obtain independence. After the revolution of July 14, 1958, the Kurds welcomed it, and the leaders of the Kurdistan Democratic Party sent a telegram to the Free Officers Organization congratulating them on the new era in order to build sound and correct relations between the two parties. However, the military conflict was renewed between the Iraqi government and the Kurds and continued even after the coup of February 8, 1963, and all the subsequent negotiating and peaceful attempts to resolve the Kurdish problem until 1966. It was a state of double contradiction for both parties that thwarted the peaceful attempts. The

AbstractDue to the wide distribution through the Iranian Plateau, especially in its western parts adjacent to Iraq’s northeastern borders, the occurrence of Brandt’s Hedgehog <italic>Paraechinus hypomelas</italic> (Brandt, 1836) was suspected, but no confirmed records were made. In 2021–2023, several sightings were obtained during <italic>in situ</italic> surveys in the Bamo-Khoshk Mountains in the Kurdistan region-northeastern Iraq which confirm the first occurrence of this species in the country.
