Excessive usage of chemicals in crops, especially in leafy vegetables, caused people exposed to health and environmental risks. In Iran, spinach used as a winter vegetable that believed has high Iron and is useful for anemia. The objective of the experiment was to determine the optimum use of each macronutrients to obtain safe maximum growth and yield for scaling up among farmers. Treatments were chemical fertilizers including ammonium sulfate, triple superphosphate and potassium sulfate at 50, 100, 150 and 200 kg/h against control in a randomized complete block design. Results showed that nitrogen caused elevation of fresh and dry weight in spinach as the maximum obtained in 200 kg/h ammonium sulfate. Results obtained from effect of phosphorus showed that super phosphate increased fresh and dry weight of spinach; but potassium sulfate had no effect on its growth and yield. Analysis of variance on cross effect of data showed significant differences in fresh and dry weight, number of leaves, chlorophyll content and nitrate, and non-significant differences in length and wide of leaves.
This study applies the multiple streams theory. It will further analyze the internal factors of the confluence of multiple sources, in order to explain why the “Joint Recruitment of Four Universities in Macao” policy has become the agenda of the Macao government. The entrance examination requirements from Macau universities are various. They increase local students’ pressure and consume their energy, thus serving as the source of the Problem Stream. The Policy Stream is represented by the Macau government’s intention to reduce students’ educational burden through establishing a unified assessment system. The Political Stream includes the Macau government’s commitment to improving the Macau education system, such as strengthening the multi-assessment system and the “The Fundamental Law of Non-tertiary Education System”. The convergence of these three sources has opened a policy window for the “Joint Recruitment of Four Universities in Macao” system, leading to a new student evaluation system. This policy not only addresses Macau’s social challenges and improves education governance while also highlighting the city’s educational diversity endeavors. Additionally, the strategies for implementing the “Four-University Joint Examination” policy include reducing the number of exams for students, implementing multi-education and multi-enrollment in higher education institutions, analyzing and improving the examination system based on educational big data, and understanding the basic elements and integration paths of big data in higher education. The Macau government can adjust major settings and enrollment quota allocation in the future, draw in more students from the Community of Portuguese-Speaking Countries and the “Belt and Road” regions, and integrate the joint admission method into the Greater Bay Area education cooperation in order to meet the needs of the growing Macao education industry.
This study aims to analyze Closed Varosha, a prominent tourist destination in the Eastern Mediterranean, as a traumatic landscape in the 1970s. This study also seeks to evaluate this site from the perspective of landscape architecture, with a particular focus on urban memory and dark tourism concepts, and to introduce the concept of “traumatic landscapes” to the existing literature on the subject. The case study analysis, on-site observation and document examination techniques were employed as research methods. A comprehensive literature review was conducted as part of this study, encompassing data on Closed Varosha, the study area, and its surrounding context. The Varosha city visited with the assistance of a travel guide, and comprehensive information and visual materials (photographs, video footage, etc.) collected in the field study. Study results proposed that the landscapes where social traumas are experienced and which have become a symbol should be used for cultural and scientific activities. This may be achieved by making use of urban memory in order to transform these landscapes into an improved version of the existing ones. Furthermore, this could serve to awaken the awareness of universal peace in visitors within the scope of dark tourism. Another potential avenue for exploration is the organization of common sense workshops with the participation of stakeholders from both communities. This could facilitate the development of future solutions through a participatory approach. Additionally, there is a need to expand transnational and multidisciplinary studies. This would enable future generations to engage in dialogue about Closed Varosha in a constructive manner.
