Emotional Intelligence: A Key for Nurse Managers’ Transformational Leadership Style

A review of the relationship between emotional intelligence and leadership outcomes described the ongoing debate between the proponents and critics of emotional intelligence as one that “thrives on hyperbolic claims on one hand, and empirical evidence to the contrary on the other”. The relationship between emotional intelligence with transformational leadership among nurse managers has received particular attention in these study, which can be attributed to both its popularity in the leadership and specific elements of transformational leadership style that seem relevant to emotional intelligence. Aim of the study: This study aims to explore emotional intelligence as the key “concept of possibility” to ignite transformational leader behavior. Research design: The design of study is descriptive correlation research design. Setting: The study was conducted at one hospital of the ministry of health hospitals. Sample: A convenient sample of (48) nurse managers. Tools of data collection: Tool 1: Background data sheet: it covered data related to age, gender, qualification, position, years of nursing experiences, years of nursing management experiences, if he/she has leadership program before and if he/she has an emotional intelligent program before. Tool 2: Multifactor Leadership Questionnaire (MLQ) Form 6S. This questionnaire provides a description of leadership style on seven factors; each factor has three items, related to transformational leadership. Tool 3: The Wong and Law Emotional Intelligence Scale (WLEIS) which consists of 16 items measures four dimensions. Result: the study conducted that there is a positive correlation between emotional intelligent and transformational leadership style among nurse managers. Conclusion and Recommendations: Offering continuing education, course content in curriculum education or professional development opportunities to develop emotional intelligence, as a key for transformational leadership that could have significant implications for health care systems, the quality of management skills, and for preparing effective future nurse managers.

Solar desalination/purification (solar stills, humidification-dehumidification, solar disinfection) in high altitude during COVID19: Insights of gastrointestinal manifestations and systems' mechanism.

From the starting of the pandemic different transmission routes of the pathogen was brought into the spotlight by researchers from different disciplines. This matter in high-altitudes was more boosted as the main parameters were not exactly realized. In this review we are about to highlight the possibility of consuming contaminated water generated form solar water desalination/disinfection systems in highlands. Three systems including solar still, solar disinfection (which experimented by the authors in 2019 in high altitude) and humidification-dehumidification were consider in this context. Ascribe to the risks of pathogens transmission in solar desalination/disinfection systems where the water resources are heavily polluted in every corner of the world, highlighting the risk of consuming water in high-altitude where there are many other parameters associated with spread of pathogen is of great importance. As it was reported, reliability of solar desalination and solar water disinfections systems against contaminated water by the novel coronavirus remained on the question because the virus can be transmitted by vapor in solar stills due to tiny particle size (60-140 nm) and would not be killed by solar disinfections due to low-temperature of operation <40 °C while for HDH contamination of both water and air by sars-cov-2 could be a concern. Although the SARS-CoV-2 is not a waterborne pathogen, its capability to replicate in stomach and infection of gastrointestinal glandular suggested the potential of transmission via fecal-oral. Eventually, it was concluded that using solar-based water treatment as drinking water in high altitude regions should be cautiously consider and recommendations and considerations are presented. Importantly, this critical review not only about the ongoing pandemic, but it aims is to highlight the importance of produced drinking water by systems for future epidemic/pandemic to prevent spread and entering a pathogen particularly in high-altitude regions via a new routes

Theoretical study of thermoelectric cooling system performance

This work provides a theoretical investigation to study the effect of different operational parameters on theperformance of TE cooling system including the system COP and the rate of heat transfer. The parametersinvestigated are, the applied input power, inlet working fluid velocity, the arrangement of utilized TECs modules andfluid type. The geometry is created with ANSYS multi-physics software as a two-dimensional base case, it isconsisted from two attached horizontal ducts of length (520 mm) and (560 mm), the interface surface between the twoducts contains three thermoelectric modules (4 mm height by 40 mm wide and 40 mm length). The distance betweentwo consecutive thermoelectric modules (150 mm), the inlet and outlet duct diameter (15 mm) and the height of eachduct (10 cm), the inlet voltage to thermoelectric modules ranges from 8.0 V to 12 V and the water inlet velocity to thetwo ducts from 0.001 to 0.01 m/s. Theoretical results showed that the overall COP of TE cooling system is increasedwith the applied input power up to 8.0 W then it decreases with input power up to 18 W after that it takes nearly aconstant value, a noticeable enhancement in the COP is found when the three TECs are in use (Case 10) and the COPof TE cooling system using pure water and nanofluid with 0.05% of nanoparticles as coolants takes the maximumvalue

The Correlation of Critical Thinking Disposition and Approaches to Learning among Baccalaureate Nursing Students

Background: Part of the 21st century skills is critical thinking and learning approaches of students. A part of that resurgence can be attributable to several studies on critical thinking, logic, and thinking skills. Health care professionals are challenged by the complexities of the health care environment. The practice of nursing requires critical thinking and clinical reasoning to define a client’s problem, examine the evidence-based practice in caring for the client, and make choices in the delivery of care.

Visual Evoked potential signal processing and analysis for normal and galucomic eyes

Visual evoked potentials (VEPS) are obtained from optic tract by recording the evoked potentials generated by retinal stimulation. The flash VEP (FVEP) is used less frequently than pattern reversal VEP (PRVEP) because; it shows great variation in both latency and amplitude. The present study was undertaken to evaluate the effect of change of wavelength of flash and change of check size on the parameters of visual evoked potential (amplitude and latency) in normal individuals and glaucoma patients. The group of healthy subjects in the age of 20-45 years while the group of glaucoma subjects where in the age of 25-50 years. The two groups were exposed to flash VEP with white light and blue color and they also were exposed to checks subtending a visual angles of 15, 30,60 and 120 minutes of arc. The measured data were statistically analyzed and summarized by histograms. The interindividual and intraindividual in latencies and amplitudes for FVEP were assessed using the coefficient of variation (COV). In conclusion, monochromatic flash VEP was preferred than white as there were minimal inter and intra individual variation of latencies and amplitudes. The most preferred check size in PRVEP was 120' for the two groups

Design of a Circular Concentric Microstrip Patch Antenna Array for WI-FI Band Energy Harvesting

Wireless networks have gone through unprecedented changes in the last decade owing to the rise in the number of users. Radio frequency (RF) energy harvesting (EH) (termed as RF-EH) can be a potential solution to exploit this traffic in communication systems, one of the key issues is designing a compact antenna array while providing reliable capturing characteristics over the operating band. In energy harvesting systems, printed slot antennas have received much attention owing to their matching characteristics. In addition, they present really appealing physical features, such as simple structure, small size, and low cost. In this paper, a small circular concentric antenna array utilizing rectangular radiating patch elements and defected ground structure for RF-EH is proposed. The antenna is designed using the CST Microwave Studio software package and realized on a Roger 5880 substrate with ���� = 2.2 and ℎ = 3.18 ����. The simulations demonstrated the effective performance of the proposed circular antenna array structure in terms of high gain of about 15.8 dBi, high efficiency, and the possibility to collect RF power from all direction

A Review of Hybrid Humidification and Dehumidification Desalination Systems

The escalating threat of water scarcity, coupled with the inclusion of numerous countries in the list of water-scarce nations, has elevated the issue of water availability to a paramount concern in today\u27s global landscape. Freshwater sources are becoming increasingly scarce, with their proportional decline steadily progressing. Consequently, a growing number of nations have resorted to the desalination of seawater as a viable solution. In response to this critical need, a surge of studies and research endeavors has been dedicated to the development and refinement of desalination processes. One of the most promising innovations in this field is Humidification-Dehumidification (HDH) desalination technology. This paper aims to delve into the potential of HDH desalination technology and its integration with another advanced desalination method known as a hybrid system. By combining these two distinct approaches, it becomes possible to not only enhance productivity but also address certain limitations inherent in each technology. In this paper, we provide an overview of various desalination processes, shedding light on their classifications and characteristics. Our primary focus, however, lies in exploring how HDH desalination technology can be effectively harmonized within a hybrid system to maximize efficiency and mitigate shortcomings observed in individual technologies. The integration of HDH with existing desalination methods has demonstrated notable success, as evidenced by numerous research studies in the field. This research underscores the significance of hybridization in advancing HDH sustainability practices within the desalination sector, ultimately contributing to the global effort to combat water scarcity
