Stylistics of Syntactic Layer in the Story of Samak-e Ayyar
No full textIn stylistics, surface structures are very important. The surface structure that the author chooses from possible surface structures to express his view of deep structure causes to produce sub-meanings, resonances, stylistic, and rhetorical devices. Thus, the syntactic structure of a text plays an important role in its style. The story of Samak-e Ayyar is one of the most prominent championship chivalry written in the sixth century. Using the descriptive-analytic method, this study examines the syntactic layer of the tale and its proportion to the theme. The most important features are artistic conciseness; high frequency of verbs in sentences; abundance of short sentences, independent and dependent sentences; the beginning of verbs, displacement part of sentences because of rhetorical motive, the abundance of active and state verbs, and creating active voice, use of prefixed verbs, the emergence of grammatical mood in verbs of sentences, dominant of the indicative mood, rising and falling intonation in speech. Also, linking sentences are a mixture of discrete and coherent styles that give the story some kind of movement and fluency. It can be said that the syntactic structure of this story is proportional to its theme and plays a key role in its conveyance of meaning, clarity, enjoyment, and acceptance
The Possible Impacts of Different Global Warming Levels on Major Crops in Egypt
No full textClimate change implications are a severe risk to food security and the economy. Global warming could disturb the production of both rainfed and irrigated agriculture thru the amplify of yield water requests in many areas. In this study, the fast-track projections available through the Inter-Sectors Impact Model Intercomparison Project (ISI-MIP) were presented and analyzed to assess the effects of two global warming (GW) levels (1.5 and 2.0 °C) on the maize and wheat yields in Egypt. Outcomes proposed spatial variations in the effects of temperature change on crop yield. Compared with the referenced situation, an observed national average change in wheat yield about 5.0% (0.0% to 9.0%) and 5.0% (−3.0% to 14.0%) under GW1.5 and GW2.0 respectively. While for maize yield, the change in national average about −1.0% (−5.0% to 3.0%) and −4.0% (−8.0% to 2.0%) under GW1.5 and GW2.0 respectively. GW1.5 could be helpful for wheat yield, but the positive effect decayed when the warming level reached 2.0 °C overhead the pre-industrial level. Nevertheless, the possible deviations to Egypt’s maize production under the GW1.5 and GW2.0 scenarios are unclear where the models do not agree with the sign of change. Adjusting the temperature rise within 1.5 °C would diminish the yield reduction, as it is an extraordinary priority to safeguard crop production. To achieve Progress of innovative agronomic managing plans and swapping to additional drought-resistant crops may be valuable for coping with climate change in regions vulnerable to yield decline
A stable porous vessel for photocatalytic degradation of Azocarmine G dye
No full textPorous nanocomposite of polystyrene (PS) is fabricated by non-solvent induced phase separation, and with the addition of ZnO nanomaterials through electrospinning, the different evaporation rates of solvent/non solvent mixture causes phase separation and improves the porosity of the fiber. The spherical particles of ZnO are uniformly distributed within the polymer chains, creating a networking effect that further restricts the motion of the PS chains and higher pores generation. The specific surface area and average pore size values were respectively 48 m2/g and 82.5 nm for the PS/ZnO with 3 wt% filler concentration, much higher than the neat polymer (23 m2/g and 61.1 nm). The PS/ZnO composite showed 95% degradation efficiency when irradiated with natural sunlight for Azocarmine G dye. This study addresses the correlation of porous structural characteristic with the sunlight driven photocatalysis as the porous sites provide active centers for the catalysis to take place. The porous structural integrity is maintained, and improved with ZnO addition and promising catalysis efficiency is achieved. Moreover, the ZnO imparts excellent antibacterial activity against S. aureus bacteria and the PS/ZnO fibers show good functional and structural stability.This publication was made possible by NPRP grant 10-0127-170269 from the Qatar National Research Fund (a member of Qatar Foundation ).

No full textExpanding her previous research on the literary representation of ‘ayyār, in this stimulating article the author offers a new insight into the evolution of this character type. M. Gaillard, who has already made important contributions to the study of the Samak-e ‘Ayyār (ca. 12 c.), here bases her investigation on a number of other works within the genre of Persian prose romance, namely, Qeṣṣe-ye Ḥamze (10-13 c.), Joneyd-nāme (ca. 15 c.), Dārāb-nāme-ye Bīġamī (14-15 c.), and ‘Ālam Ārā-ye Nāder..
Studying the effect of tillage depth combined with organic amendments and different nitrogen fertilization on improving calcareous soil properties and wheat productivity
No full textCalcareous soil suffers from deprived organic materials, structural properties, increased water holding capacity, deep percolation, crusts and cracks formation, which hinders the roots dispersion and decreases permeation speed. This inhibits the soil physical, hydraulic properties, and its nutritional status. The research objective is to enhance the calcareous soil status and its productivity using eco-friendly conditioners. A Split-split plot field experimental study has been laid at El-Nubaria Agri. Res. Stat., in 2018 and 2019 winter seasons with three replications. The main factor was two depths of tillage: (T1) surface tillage (0 – 15 cm) and (T2) deep tillage (0 – 60 cm). The sub-main factor was three types of mineral nitrogen (N) fertilization, control (C1) without N application, ammonium nitrate (F1) and urea formaldehyde (F2), while the sub-sub main factor was the types of soil amendments: no amendment (cont.), sugar beet waste (W), K-Humate (KH), Sulphur (S) and compost (Comp). Results have indicated that greater values of organic matter OM and aggregate measured were gained by the surface tillage treatment and using both sugar beet wastes (W) and compost applications. The combination between the deep tillage (T2) and ammonium nitrate (F1) and sugar beet waste (W) has increased the wheat grains and straw yield (ton ha-1) and 1000-grains weight (g). Sugar beet waste can be recommended as an economic conditioner enhances the calcareous soil to make it more productive
Fostering Sustainable Potato Prod: Enhancing Quality & Yield via Potassium & Boron Applications
No full textBoron deficiency significantly limits potato yield and quality in alkaline soils. This study investigated the impact of potassium and boron applications on potato yield and quality in boron-deficient alkaline soils, crucial aspects of sustainable potato farming. We evaluated the effects of soil and foliar applications of various potassium (silicate, alginate, citrate, sulfate) and nano-boron sources on potato growth, yield, and tuber quality. Two field trials, conducted over two growing seasons, demonstrated that foliar application of potassium silicate significantly enhanced potato yield and quality parameters, including tuber number, total yield, boron content, vitamin C content, and specific gravity. Foliar nano-boron application also significantly improved growth and yield compared to the control and soil-applied boron. The combination of foliar potassium silicate and nano-boron yielded the most superior results. Potassium silicate outperformed other potassium sources. These findings highlight the importance of foliar application for optimizing potassium fertilization and mitigating boron deficiency, promoting agricultural sustainability in alkaline soil conditions characteristic of many potato farming regions. Further research could explore optimal application methods and dosages for maximizing the synergistic effects of these nutrients
Does foreign portfolio investment reach small listed firms ?
No full textUsing a unique dataset, the author examines the impact of foreign portfolio investment on the capital issuance behavior of small listed firms. The author finds that foreign portfolio investment is associated with an increased probability of small firm security issuance in all nations, regardless of property rights development. Evidence suggests the mechanism by which this occurs is a freeing up of capital in domestic markets when large firms utilize the foreign investment directly. Debt levels in nations where property rights are more developed increase, suggesting that foreign portfolio investment may reach small firms through the banking channel as well as capital markets in these nations.Debt Markets,Access to Finance,Economic Theory&Research,Emerging Markets,Investment and Investment Climate
