Effect of fertilizers on growth and productivity of saffron: a review

Received: October 21st, 2022 ; Accepted: December 13th, 2022 ; Published: December 21st, 2022 ; Correspondence: [email protected] management involves a systematic approach to nutrient management. Controlling the amount, form, combinations and timing of nutrients delivered to plants is a prerequisite for getting optimum yield and quality potential of saffron. Therefore, nutrient use efficiency and integrated nutrient management is a crucial tool for balanced fertilization and sustainable crop production. The impact and the need of organic and inorganic fertilization for saffron growth are discussed along with the possibilities of increasing qualitative and quantitative parameters by the integration of multiple fertilizers. The goal of this review is to give an overview of saffron nutrition management in order to maximize saffron growth and yield

A Survey of Air-to-Ground Propagation Channel Modeling for Unmanned Aerial Vehicles

In recent years, there has been a dramatic increase in the use of unmanned aerial vehicles (UAVs), particularly for small UAVs, due to their affordable prices, ease of availability, and ease of operability. Existing and future applications of UAVs include remote surveillance and monitoring, relief operations, package delivery, and communication backhaul infrastructure. Additionally, UAVs are envisioned as an important component of 5G wireless technology and beyond. The unique application scenarios for UAVs necessitate accurate air-to-ground (AG) propagation channel models for designing and evaluating UAV communication links for control/non-payload as well as payload data transmissions. These AG propagation models have not been investigated in detail when compared to terrestrial propagation models. In this paper, a comprehensive survey is provided on available AG channel measurement campaigns, large and small scale fading channel models, their limitations, and future research directions for UAV communication scenarios

Challenges and Opportunities in Sourcing, Preparing and Developing a Teaching Force for the UAE

Teacher education occurs along a continuum that encompasses teacher candidate recruitment, teacher candidate preparation, novice teacher induction, teacher professional development, and advanced teacher qualifications. Since the formation of the state in 1971, teacher recruitment and teacher education in the UAE have undergone several stages of development, beginning with the sourcing of teachers from the Arab world, through the establishment of in-country teacher education programs designed to produce native teachers, to the hiring of teachers from high performing school systems in the Anglophone world. Teacher education is quite a challenging enterprise, being impacted by changes in the constantly evolving education system in this young nation. High-quality teacher education candidates can be elusive, and it is difficult to attract nationals to teaching, especially males. Yet, at the same time, there are opportunities for teacher education as the country works valiantly to raise educational standards, including the development of Arabic language teacher education, the provision of continuing professional development around teacher licensure, and induction programs for novice teachers

A new hereditary colorectal cancer network in the Middle East and eastern mediterranean countries to improve care for high-risk families

Colorectal cancer (CRC) has a very high incidence in the western world. Data from registries in the Middle East showed that the incidence of CRC is relatively low in these countries. However, these data also showed that CRC incidence has increased substantially over the past three decades and that a high proportion of cases are diagnosed at an early age (<50 years). In view of these findings, more attention should be paid to prevention. Because of the often limited financial resources, focused screening of individuals with hereditary CRC, in particular those with Lynch syndrome, appears to be the most cost-effective strategy. During recent meetings of the Palestinian Society of Gastroenterology and the Mediterranean Task force for Cancer Control (MTCC) in Jericho, and the Patient�s Friends Society of Jerusalem in Hebron the issue of hereditary CRC in the Middle East was discussed and the idea was conceived to establish a network on hereditary colorectal cancer (HCCN-ME) with the goal of improving care for high-risk groups in the Middle East and (Eastern) Mediterranean Countries. © 2017, The Author(s)

Pediatric Measles Vaccine Expressing a Dengue Antigen Induces Durable Serotype-specific Neutralizing Antibodies to Dengue Virus

Dengue disease is an increasing global health problem that threatens one-third of the world's population. Despite decades of efforts, no licensed vaccine against dengue is available. With the aim to develop an affordable vaccine that could be used in young populations living in tropical areas, we evaluated a new strategy based on the expression of a minimal dengue antigen by a vector derived from pediatric live-attenuated Schwarz measles vaccine (MV). As a proof-of-concept, we inserted into the MV vector a sequence encoding a minimal combined dengue antigen composed of the envelope domain III (EDIII) fused to the ectodomain of the membrane protein (ectoM) from DV serotype-1. Immunization of mice susceptible to MV resulted in a long-term production of DV1 serotype-specific neutralizing antibodies. The presence of ectoM was critical to the immunogenicity of inserted EDIII. The adjuvant capacity of ectoM correlated with its ability to promote the maturation of dendritic cells and the secretion of proinflammatory and antiviral cytokines and chemokines involved in adaptive immunity. The protective efficacy of this vaccine should be studied in non-human primates. A combined measles–dengue vaccine might provide a one-shot approach to immunize children against both diseases where they co-exist
