Field trials were conducted on a private farm cultivated with lime trees, Citrus aurantifolia Frank, 4 years old, in Kom Hamada, Behaira governorate. The influence of certain insecticides, oils, and foliar fertilizers was studied against citrus leafminer Phyllocnistis citrella on lime trees. The insecticides included abamectin, spinetoram, thiocyclam, azadirachtin, lambda-cyhalothrin, and profenofos; two oils (mineral and vegetable oils); and two foliar fertilizers (calcium nitrate and potassium nitrate). The results indicated that abamectin consistently showed the highest efficacy in eliminating the citrus leaf miner, on lime trees. This effectiveness was observed over five consecutive administrations conducted during the 2021 growing season. The treatment with abamectin exhibited the highest level of efficacy among the several treatments that were evaluated. It yielded reduction percentages of 79.60%, 85.90%, 81.20%, 89.40%, and 92.10%, respectively, and a grand reduction of 85.64%. The application of mineral oil came in the second order and resulted in a decrease in infestation levels by 64.90%, 63.10%, 65.70%, 70.90%, and 70.50% after five consecutive applications, with a grand reduction of 67.03%. Meanwhile, the treatments of vegetable oil, spinetoram, and lambda-cyhalothrin produced medium-significant reductions in infestation (̰50%), revealing grand reductions of 52.50, 52.04, and 49.92%, respectively, among the five consecutive applications. Based on the results of our research, it is evident that abamectin as well as mineral oil remain viable and advantageous options for effectively controlling the citrus leaf miner infestation in juvenile lime trees.
在贝海拉省科姆哈马达(Kom Hamada)一个种植了 4 年菩提树(Citrus aurantifolia Frank)的私人农场进行了实地试验。研究了某些杀虫剂、油和叶面肥对柑橘潜叶蝇(Phyllocnistis citrella)在菩提树上的影响。杀虫剂包括阿维菌素、辛硫磷、噻虫嗪、唑虫啉、氰戊菊酯和丙溴磷;两种油(矿物油和植物油);以及两种叶面肥(硝酸钙和硝酸钾)。结果表明,阿维菌素在消灭菩提树上的柑橘潜叶蛾方面一直表现出最高的效力。这种效果是在 2021 年生长季节连续施药五次后观察到的。在评估的几种处理方法中,阿维菌素处理的效力最高。其减少率分别为 79.60%、85.90%、81.20%、89.40% 和 92.10%,总减少率为 85.64%。矿物油的施用量排在第二位,连续施用五次后,虫害水平分别下降了 64.90%、63.10%、65.70%、70.90% 和 70.50%,总降幅为 67.03%。同时,植物油、辛硫磷和高效氯氟氰菊酯处理对虫害有中等程度的减少作用(̰50%),在连续施药五次后,虫害的总减少率分别为 52.50%、52.04%和 49.92%。根据我们的研究结果,阿维菌素和矿物油显然仍是有效控制菩提幼树柑橘潜叶蛾虫害的可行且有利的选择。

Date palms are important crop in arid and semi-arid regions because they provide food, income, and cultural significance. However, their cultivation is threatened by diseases such as root rot caused by various fungi. Climate change increases temperature stress, which worsens the severity of root rot. To predict the effects of temperature stress on date palm root rot, modeling techniques are used to simulate the complex relationships between temperature, fungal pathogens, and date palm health. These models enable the prediction of disease outbreaks under different climate scenarios. This study used meteorological data from the National Center for Environmental Information from 1988 to 2019. By analyzing the average air temperature and the severity of pathogenic fungi that cause root rot in date palms, the relationship between these variables was determined. The study took place at Kharga Oasis in New Valley governorate, where average temperatures over 32 years were observed. The influence of temperature stress on date palm root rot depends on factors such as date palm variety, fungal species, and other environmental factors. By integrating temperature monitoring, predictive modeling, and a deep understanding of the correlation between root rot and temperature, an efficient forecasting system can be established. To effectively control date palm root rot, integrated management strategies that include cultural practices, fungicides, and the use of resistant varieties are likely to achieve the best results. This comprehensive approach addresses the various factors that contribute to date palm root rot, promoting sustainability, and protecting this important crop from the threats it faces.
枣椰树是干旱和半干旱地区的重要作物,因为它们能提供食物、收入和文化意义。然而,它们的种植受到各种真菌引起的根腐病等病害的威胁。气候变化增加了温度胁迫,从而加剧了根腐病的严重程度。为了预测温度胁迫对椰枣根腐病的影响,使用了建模技术来模拟温度、真菌病原体和椰枣健康之间的复杂关系。这些模型可以预测不同气候条件下的病害爆发情况。本研究使用了国家环境信息中心 1988 年至 2019 年的气象数据。通过分析平均气温和导致枣椰根腐病的病原真菌的严重程度,确定了这些变量之间的关系。研究在新山谷省的哈尔加绿洲进行,在那里观测了 32 年的平均气温。温度胁迫对椰枣根腐病的影响取决于椰枣品种、真菌种类和其他环境因素。通过整合温度监测、预测模型以及对根腐病与温度之间相关性的深入了解,可以建立一个高效的预测系统。要有效控制枣椰根腐病,包括栽培措施、杀菌剂和使用抗病品种在内的综合管理策略可能会取得最佳效果。这种综合方法可以解决导致椰枣根腐病的各种因素,促进可持续性,保护这种重要作物免受威胁。

This study aims to test and examine the importance of innovation and performance for private and public organizations. Many organizations were benefiting from innovation in order to develop and improve their performance, while many studies have found empirical evidence of the importance of innovation in achieving higher performance in both the public and private sectors. At the same time, many argue Scientists say that this field still lacks scientific research, which creates a clear gap between theoretical and practical knowledge in the field of innovation and the performance of its importance as a result. Therefore, economic growth has been linked to the level of technology, as research has found at the same time a clear relationship between innovation and performance, the direct motivation for institutions to use and implement innovation strategies. Whether simple or complex strategies have proven their effects in increasing the performance of enterprise products, productivity and competitive advantage in the new market while at the same time reducing the cost of production. This study comes to investigate the impact of innovation on financial and non-financial performance in Egyptian organizations, as this area of research has not been explored in the literature. Therefore, this study comes in the hope of providing and adding guidance and a preliminary framework for future research on innovation and its impact on performance in Palestine. To achieve this, the study used types Innovation as the independent variable and organizational performance (financial and non-financial performance) as the dependent factor, and the variables were activated in line with the objectives of the study.
本研究旨在检验和研究创新与绩效对私营和公共组织的重要性。许多组织正在从创新中获益,以发展和提高其绩效,而许多研究也发现了实证证据,证明创新在公共和私营部门实现更高绩效方面的重要性。与此同时,许多科学家认为,这一领域仍然缺乏科学研究,这使得创新领域的理论和实践知识之间存在明显差距,创新的重要性也因此表现出来。因此,经济增长与技术水平息息相关,因为研究同时发现创新与绩效之间存在明确的关系,这也是各机构使用和实施创新战略的直接动力。事实证明,无论是简单还是复杂的战略,都能提高企业产品的性能、生产率和在新市场中的竞争优势,同时降低生产成本。本研究旨在调查创新对埃及组织的财务和非财务绩效的影响,因为这一研究领域尚未在文献中得到探讨。因此,本研究希望为今后研究创新及其对巴勒斯坦绩效的影响提供指导和初步框架。为此,本研究将创新类型作为自变量,将组织绩效(财务和非财务绩效)作为因变量,并根据研究目标对变量进行了激活。

The study aimed to test the impact of environmental disclosure on the application of corporate governance mechanisms. Environmental disclosure is the process by which information on environmental obligations resulting from the systems’ exercise of these obligations is presented so that various stakeholders can obtain the information necessary for planning, control, and performance evaluation. This is meant by corporate governance. The rules through which the company is led and directed include mechanisms to regulate the various relationships between the Board of Directors, executive directors, shareholders and stakeholders, by establishing special procedures to facilitate the decision-making process and give it a transparent and credible character for the purpose of protecting the rights of shareholders and stakeholders and achieving justice, competitiveness and transparency in the market and business environment. Data and information were collected using a survey list, as well as the field presence of the two researchers. The data was analyzed using the statistical program (SPSS) and a set of statistical methods. The study found a significant effect of environmental disclosure on the application of corporate governance mechanisms in companies listed on the Libyan Stock Exchange.
这项研究旨在检验环境披露对公司治理机制应用的影响。环境信息披露是一个过程,通过这个过程,各利益相关方可以获得规划、控制和绩效评估所需的环境义务信息。这就是公司治理。领导和指导公司的规则包括调节董事会、执行董事、股东和利益相关者之间各种关系的机制,通过建立特别程序来促进决策过程,使其具有透明性和可信性,以保护股东和利益相关者的权利,实现市场和商业环境的公正性、竞争力和透明度。数据和信息的收集采用了调查列表以及两位研究人员的实地考察。数据使用统计程序(SPSS)和一套统计方法进行分析。研究发现,环境信息披露对利比亚证券交易所上市公司公司治理机制的应用有重大影响。

The research aims to study and test the impact of the relationship between the disclosure of the Environmental Sustainability of Libyan companies with its dimensions (Environmental Sustainability towards society, Environmental Sustainability towards employees, Environmental Sustainability towards the environment, Environmental Sustainability towards shareholders) and the profitability of the company. The recent changes facing the environmental Sustainability have contributed to the increasing interest of researchers and regulatory bodies in environmental issues and companies' disclosure of information. Environmental disclosure is an important component, but there are few studies on environmental disclosure. The researcher used the questionnaire for the purpose of achieving the goal of the research, and the research community consisted of all the employees of the Libyan companies, and a random sample was chosen from the study community, as (250) questionnaires were distributed, and the number of retrieved questionnaires reached (221) at a rate of (88.4%), and thus the number of questionnaires became The valid questionnaires that were subjected to statistical analysis are (221) questionnaires from the total number of distributed questionnaires. The results of the research showed that there is an effect of disclosing corporate Environmental Sustainability in its dimensions (Environmental Sustainability towards society, Environmental Sustainability towards employees, Environmental Sustainability towards the environment, Environmental Sustainability towards shareholders) on corporate profitability, and there is a statistically significant effect at a significant level (α≤0.05). For the disclosure of Environmental Sustainability towards society on the profitability of Libyan companies, and the existence of a statistically significant effect at the level of significance (α≤0.05) for the disclosure of Environmental Sustainability towards employees on the profitability of Libyan companies, And there is a statistically significant effect at a significant level (α≤0.05) for disclosing Environmental Sustainability towards the environment on the profitability of Libyan companies, and there is a statistically significant effect at a significant level (α≤0.05) for disclosing Environmental Sustainability towards shareholders on the profitability of Libyan companies
本研究旨在研究和测试利比亚公司披露环境可持续性信息的维度(对社会的环境可持续性、对员工的环境可持续性、对环境的环境可持续性、对股东的环境可持续性)与公司盈利能力之间关系的影响。环境可持续发展所面临的最新变化促使研究人员和监管机构越来越关注环境问题和公司的信息披露。环境信息披露是一个重要组成部分,但有关环境信息披露的研究却很少。为实现研究目标,研究人员采用了问卷调查法,研究对象包括利比亚公司的所有员工,并从研究对象中随机抽取样本,共发放问卷(250 份),回收问卷(221 份),回收率为(88.4%),因此问卷数量为 从发放的问卷总数中抽取有效问卷(221 份)进行统计分析。研究结果表明,披露企业环境可持续发展各维度(对社会的环境可持续发展、对员工的环境可持续发展、对环境的环境可持续发展、对股东的环境可持续发展)对企业盈利能力有影响,且在显著水平(α≤0.05)上有统计学意义。对社会的环境可持续发展信息披露对利比亚公司盈利能力的影响,以及对员工的环境可持续发展信息披露对利比亚公司盈利能力的影响在显著性水平(α≤0.05)上存在统计学意义上的显著影响;对环境的环境可持续发展信息披露对利比亚公司盈利能力的影响在显著性水平(α≤0.05)上存在统计学意义上的显著影响;对股东的环境可持续发展信息披露对利比亚公司盈利能力的影响在显著性水平(α≤0.05)上存在统计学意义上的显著影响。

The management of the municipal solid waste system is one of the important environmental issues that haunt the governments of some countries, so they strive to enact legislation that guarantees integrated management. International legislation, laws, and agreements recognize the human right to live in a clean environment. During the past years, we find that the environmental legislation in Egypt did not give sufficient attention to municipal (household) waste management, and radical solutionsthat can be applied has absented.Perhaps this is due to the absence of specialized legislation or to the weakness of its texts, or the result of the failure to apply these texts in a manner that satisfies the ordinary individual in society.This research aims to evaluate the role of these legislations in achieving the integrated and correct management of municipal solid waste and using it in an economically beneficial manner.The descriptive analytical approach, which includes data collection, understanding, measurement, interpretation, and analysis, was used to verify the adequacy of the current legislation in regulating solid (municipal) waste management in Egypt, and then identify the deficiencies in these legislations, and provide appropriate recommendations to address the weaknesses. The findings showed that the current specialized legislation dealing with this issue is a great achievement that may have been long overdue for decades, but it may not be sufficient, and its practical application suffers from some weaknesses, which stand in the way of completely eliminating the negative environmental and health manifestations associated with municipal solid waste system management.
城市固体废物系统的管理是困扰一些国家政府的重要环境问题之一,因此这些国家政府努力制定法律,以保证综合管理。国际立法、法律和协议承认在清洁环境中生活的人权。在过去的几年中,我们发现埃及的环境立法并没有对城市(家庭)废物管理给予足够的重视,也没有可以应用的根本性解决方案。这也许是由于缺乏专门的立法或其文本的薄弱,或者是由于未能以满足社会中普通个人的方式应用这些文本。本研究旨在评估这些立法在实现综合、正确管理城市固体废物以及以经济有益的方式利用这些废物方面的作用。研究采用描述性分析方法,包括数据收集、理解、测量、解释和分析,以验证埃及现行立法在规范固体(城市)废物管理方面的适当性,然后找出这些立法的不足之处,并针对这些不足之处提出适当的建议。研究结果表明,目前处理这一问题的专门立法是一项巨大成就,可能早在几十年前就应制定,但可能还不够充分,其实际应用存在一些缺陷,妨碍了彻底消除与城市固体废物系统管理有关的负面环境和健康表现。
