Abstract: The study addresses the persistent wheat production-consumption gap, estimated at around 47.5%, driven by population growth and increasing wheat demand. This situation necessitates bridging the gap by boosting per-acre wheat productivity, expanding both horizontally and vertically, and utilizing technology to increase self-sufficiency and reduce import dependence.

Objectives: The study aims to improve the economic efficiency of wheat production by encouraging farmers to adopt modern technological packages.

Key Findings: Results indicate that the total revenue from wheat in demonstration fields reached approximately 38,600 EGP per acre in Abu Hammad, around 35,920 EGP per acre in Zagazig, and 37,250 EGP per acre on average. In contrast, revenue from traditional fields was approximately 31,450 EGP per acre in Abu Hammad, around 29,600 EGP per acre in Zagazig, and averaged 30,575 EGP per acre for the sample.

It is evident that the total revenue for wheat in demonstration fields exceeds that of traditional fields by around 6,675 EGP per acre on average. This discrepancy in total revenue represents an estimated loss of 2.8 billion EGP in total wheat revenue for Al Sharqia Governorate and around 22.8 billion EGP nationwide for the same year. The results also reveal that the net income from wheat in demonstration fields reached about 16,790 EGP per acre in Abu Hammad, around 14,270 EGP per acre in Zagazig, and an average of 15,520 EGP per acre. By contrast, net income from traditional fields was around 8,700 EGP per acre in Abu Hammad, approximately 6,800 EGP per acre in Zagazig, and an average of 7,800 EGP per acre.

This analysis highlights a difference in net income of about 7,720 EGP per acre between demonstration and traditional fields.

Recommendations: 

1. Collect farmers' feedback on improving performance efficiency and addressing issues to enhance wheat production in terms of quantity and quality.

2. Reinforce the role of agricultural cooperatives in providing high-quality seeds in the required quantities, at fair prices, and at suitable times and locations.

3. Place demonstration fields at village entrances and in visible locations to encourage farmers to observe results multiple times at different stages.

4. Expand the use of wheat planting with seed drills, given their economic and productive efficiency.

Abstract: In the past decade, the field of organic synthesis has witnessed tremendous advancements in the areas of photoredox catalysis, electrochemistry, C–H activation, reductive coupling and flow chemistry. While these methods and technologies offer many strategic advantages in streamlining syntheses, their application on the process scale is complicated by several factors. In this Review, we discuss the challenges that arise when these reaction classes and/or flow chemistry technology are taken from a research laboratory operating at the milligram scale to a reactor capable of producing kilograms of product. We discuss how these challenges have been overcome through chemical and engineering solutions. Specifically, this Review will highlight key examples that have led to the production of multi-hundred-gram to kilogram quantities of active pharmaceutical ingredients or their intermediates and will provide insight on the scaling-up process to those developing new technologies and reactions.

ABSTRACT: Using animals for our purposes we exercise varying degrees of control over the quality and duration of their lives. That control gives us the opportunity to manage them humanely. Moreover, using them for our own purposes, not theirs, requires us to do so. Accordingly, we have an ethical ‘duty of care’ towards the animals in our control and this translates into a practical obligation to keep their welfare at acceptable levels. To do this we need an understanding of what animal welfare is. Moreover, when assessing the welfare status of animals in practical contexts different emphasis has been placed on different aspects of current definitions. The biological function view holds that, in general, welfare is good when the animals are healthy, growing and reproducing well. For farm animals in particular, when good meat, milk, egg and fiber productivity of individuals is broadly aligned with good health and reproductive performance. I suggest that an animal is in a poor state of welfare only when physiological systems are disturbed to the point that survival or reproduction are impaired.

Abstract: Landslide problems are abundant in the mountainous areas of Iran due to a different geological conditions, abundant rainfall and anthropogenic factors, which leads to enormous loss of life and property every year. To control such problems, systematic studies of landslides are necessary, including inventory mapping and risk assessment. This study applies the analytical hierarchy process method in the south west of Iran. A landslide susceptibility map is prepared on the basis of available digital data and remote sensing imagery. The landslide susceptibility map is produced through physical and statistical methods. The results reveal that the predicted susceptibility levels are found to be in good agreement with the past landslide occurrences, and, hence, the map is trustworthy for future land-use planning.

Abstract: The use of nanoparticles as corrosion inhibitors has gained popularity because of its increased corrosion efficiency due to increase surface to volume ratio. Nanoparticles which undergo physisorption/chemisorption to the corrosion metal surface and inhibit the corrosion efficiently also have low toxicity, low cost and easy production. In this research work, weight lost method was applied to study the inhibitive properties of silver nanoparticles (AgNPs) synthesized using Senna occidentalis root extract as environmentally benign corrosion inhibitor of mild steel in 0.5M H₂SO₄ medium at 298K and 308K. It was observed that the corrosion rate of the steel sample decreases with increase in concentration of the silver nanoparticles but increased with rise in temperature.  The highest inhibition efficiency of 65.59 % was obtained at 308K at the concentration of 5gdm^-3 and the least of 10.58% at the concentration of 1 gdm^-3 at 308K. The decrease in inhibition efficiency with rise in temperature is suggestive of physical adsorption mechanism. The surface coverage was observed to increase with increasing concentration of the nanoparticles and decreased with increase in temperature. This could be as a result of physical adsorption mechanism. The evaluated activation energy was found to be higher for the inhibited process than for the uninhibited process. The increase in apparent activation energy in the presence of the nanoparticles denotes physical adsorption mechanism, while the reverse is usually attributed to chemical adsorption. The negative values of heat of adsorption Q_ads suggest that the adsorption phenomenon is exothermic.

Abstract: This paper focuses on improving the language skills and content construction ability of science and engineering students in science and technology information communication, especially for students who do not have rich language background. To this end, we propose an innovative rapid learning teaching design, which is based on the three-stage teaching concept, including theoretical learning, observation demonstration and practical application in three stages, aiming to optimize the learning experience and improve the learning efficiency. Through theoretical analysis, we explain the key role of language technology in interdisciplinary communication and the cultivation of innovative thinking, and emphasize that the cultivation of language expression ability should not be neglected in science and engineering education. In the teaching design part, we introduce in detail how to combine theoretical knowledge with practical operation through the combination of case analysis and practical projects, students can quickly master the core skills of language technology. In addition, we also share practical cases of the implementation of this teaching reform program in science and engineering universities, showing its remarkable effect in improving students' language application ability. In the chapter of Teaching Reform Practice and Effectiveness Evaluation, we evaluate the effectiveness of this teaching reform measure based on curriculum feedback, student performance and ability improvement data. The results show that after the adoption of rapid learning instructional design, students have made significant progress in the mastery and application of media language technology, and also have a deeper understanding of interdisciplinary communication and innovative thinking. These positive changes confirm the importance and practical significance of language and technology courses in science and engineering education. To sum up, this study aims to explore effective teaching methods of language technology in science and engineering education, in order to promote the comprehensive development of science and engineering students, and lay a solid language foundation for future science and technology work and interdisciplinary cooperation. This teaching reform practice provides a valuable reference for similar courses, which is helpful to further optimize the course structure and teaching strategy of science and engineering education.

Binary opposition and conflict -- A study on the "polarity" of A Dream of Red Mansions from the perspective of imagology

GAO Minghui

Abstract: "Polarity" is an important concept put forward by German art historian Aby Warburg, the founder of iconography, which refers to a kind of binary opposition and conflict. "Polarity" is a summary of Warburg's profound thinking on the primitive society to the modern society, and it is concretely expressed as the opposition and conflict of human emotions. It embodies the symbolic forms of dualistic conflicts between human self and the external world, classical mythology and modern civilization, reason and passion, pathos and mania, Christianity and paganism. In recent years, the theory of literary images has become a hot topic in academic circles. In A Dream of Red Mansions, many characters are depicted in different ways when they face their tragic fate. By juxtating the "polarity" forms of representative characters in the text, we can conclude the presentation of the binary conflict between silence and agitation. In the study of A Dream of Red Mansions, imagology theory is used to explore how to reproduce and sublimate the meaning of A Dream of Red Mansions in the integration of Chinese and Western cultures through open and cross-border art theory. In order to explore the profound social, cultural and psychological symbolic meaning of the ancient classic A Dream of Red Mansions, which carries social memory and human emotion, and its life aesthetic connotation which has been neglected in the contemporary era.
