Kamel, S.H., R.F. Al-Jassani and H.A. Al-Shammari. 2022. Effects of Pseudomonas fluorescens, Bacillus thuringiensis tenebrionis Isolates and Biologically Synthesized Silver Nanoparticles on Cellulase Enzyme Activity in Workers' Digestive System of the Termite Microcerotermes diversus Silv. Arab Journal of Plant Protection, 40(4): 315-324. https://doi.org/10.22268/AJPP-40.4.315324 The purpose of this study was to investigate the effect of different bacterial isolates of P. fluorescens and B. t. tenebrionis and silver nanoparticles on the activity of the cellulase enzyme in termites' middle digestive system and its role in glucose release by treating cellulose media with bacterial strains and nanoparticles. Ultraviolet spectroscopy results revealed that silver nanoparticles synthesized by P. fluorescens isolated from termites, commercial P. fluorescens, and local B.t. tenrbrionis had the highest absorption at 385, 324, and 324 nm wave length, respectively. Infrared spectroscopy (FTIR) revealed that ketons, amines, alkanes, and alcohols were among the groups that contributed to silver ions reduction, capping and stabilizing nanoparticles. The particle diameters were measured using a scanning electron microscope (SEM) and found to be on average 32.43, 63.19, and 57.62 nm. The highest concentration of liberated glucose was recorded after 24 hours, which ranged between 0.453 and 1.285 mg/ml when treated with silver nanoparticles prepared from a commercial isolate of P. fluorescens bacteria and when treated with a bacterial isolate P. fluorescens, respectively. Only when treated with synthesized silver nanoparticles and when treated with commercial P. fluorescens isolates did the lowest concentrations of liberated sugar reached between 0.037 and 0.730 mg/ml after 72 hours, respectively. The high quantity of liberated sugar in the control treatment was constant, reaching 1.70 and 2.33 mg/ml after 24 and 72 hours, respectively. In addition to the variation in cellulase enzyme inhibition rates in termite digestive systems due to the effect of different treatments, it was discovered that the local isolate of B. t. tenrbrionis was better than the rest of the isolates in affecting the enzyme, causing inhibition rates of 71.42%. Furthermore, silver nanoparticles synthesized from a commercial isolate of P. fluorescens outperformed other treatments in inhibiting enzyme activity, with an inhibition rate of 78.57% . Keywords: Pseudomonas fluorescens, Bacillus thuringiensis tenebrionis, silver nanoparticles, Microcerotermes diversus

Effect of cultivars and harvest dates on rice seeds vigore
...Show More Authors

A laboratory experiment was carried out according to a completely randomized design with four repetitions on the seeds resulting from a field experiment applied for the two seasons, 2020 and 2021, to find out the effect of the cultivars (Ambar 33, Yasamin, Dijlah, Ambar Al-Baraka and Furat 1) and the harvest dates (at physiological maturity and after 7 and 14, 21 and 28 days of physiological maturity) on the vigour of rice seeds. The results showed the superiority of the seeds of the cultivar Anbar Al-Baraka at first and final counting, dry weight of the seedling, seedling vigor index and electrical conductivity, and the superiority of the seeds of Dijla cultivar at accelerated aging test and cold test without significant difference with th

Neuromemrisitive Architecture of HTM with On-Device Learning and Neurogenesis
...Show More Authors

Hierarchical temporal memory (HTM) is a biomimetic sequence memory algorithm that holds promise for invariant representations of spatial and spatio-temporal inputs. This article presents a comprehensive neuromemristive crossbar architecture for the spatial pooler (SP) and the sparse distributed representation classifier, which are fundamental to the algorithm. There are several unique features in the proposed architecture that tightly link with the HTM algorithm. A memristor that is suitable for emulating the HTM synapses is identified and a new Z-window function is proposed. The architecture exploits the concept of synthetic synapses to enable potential synapses in the HTM. The crossbar for the SP avoids dark spots caused by unutil

Adsorption and Kinetic of para-Nitroaniline on Iraqi Siliceous Rocks
...Show More Authors

UV-Vis technique has been used to study the adsorption of para-nitroaniline (PNA) on Iraqi siliceous rocks powder. Adsorption isotherms were investigated, temperature effect on adsorption was calculated, Results showed that the adsorption was an exothermic process and the thermodynamic functions were calculated. The effect of the pH on adsorption was studied and the ionic strength effect on adsorption was studied, It was found that adsorption increases with the presence of sodium chloride ions. The kinetic study of adsorption before equilibrium showed that the adsorption was pseudo first order according to according (Lagergren equation).

Literal Translation and Its Impact on Political Terms Translation in Television Journalism
...Show More Authors

The research tackles the potential challenged faced the translator when dealing with the literal translation of nowadays political terms in media. Despite the universal complexity of translating political jargon, adopting literal translation introduces an added layer of intricacy. The primary aim of literal translation is to maintain faithfulness to the original text, irrespective of whether it is in English or Arabic. However, this method presents several challenges within the linguistic and cultural dimensions. Drawing upon scholarly sources, this article expounds upon the multifaceted issues that emerge from the verbatim translation of political terms from English into Arabic. These problems include political culture, language differenc

A Review Study on Forgery and Tamper Detection Techniques in Digital Images
...Show More Authors

Digital tampering identification, which detects picture modification, is a significant area of image analysis studies. This area has grown with time with exceptional precision employing machine learning and deep learning-based strategies during the last five years. Synthesis and reinforcement-based learning techniques must now evolve to keep with the research. However, before doing any experimentation, a scientist must first comprehend the current state of the art in that domain. Diverse paths, associated outcomes, and analysis lay the groundwork for successful experimentation and superior results. Before starting with experiments, universal image forensics approaches must be thoroughly researched. As a result, this review of variou

A Review on Urban Planning and Its Role in Managing Flood Risks
...Show More Authors

This review delves deep into the intricate relationship between urban planning and flood risk management, tracing its historical trajectory and the evolution of methodologies over time. Traditionally, urban centers prioritized defensive measures, like dikes and levees, with an emphasis on immediate solutions over long-term resilience. These practices, though effective in the short term, often overlooked broader environmental implications and the necessity for holistic planning. However, as urban areas burgeoned and climate change introduced new challenges, there has been a marked shift in approach. Modern urban planning now emphasizes integrated blue-green infrastructure, aiming to harmonize human habitation with water cycles. Resil
