Assessing the need for community health nursing services in the UAE
The rapid socio-economic development in the United Arab Emirates (UAE) has had a great impact on the establishment and growth of the health care system in the country. Despite the development of the health care system, various shortcomings interact with and impact upon health and the way the health system functions and operates. Hence, the aim of this study was to assess to what extent the introduction of Community Health Care Nursing (CHCN) services in the UAE would address some of these shortcomings, In order to achieve this aim, a better understanding of the UAE health care system and health needs was required. This was obtained through a comparison with the United Kingdom and Bahrain, with a special focus on Primary Health Care and CHCN services. In recognition of the importance of the views of the public regarding any new service, fieldwork was conducted with a sample of the community and health services staff living in the city of Al Ain, UAE. The data required were collected by means of quantitative (questionnaires) and qualitative (the focus group technique and interviews) research methods. The findings from this study demonstrated that some shortcomings characterising the current health services need to be addressed before planning and implementing the proposed service. Furthermore, the results suggested that CHCN, preventive, curative or both, could contribute to meeting some of the identified health care needs. The findings also indicated a lack of understanding on the part of the general public of the function of primary, secondary and tertiary health facilities, in particular that of hospitals. It is therefore argued that PHC centres could be suitable places to host a CHCN service in the country. The findings also indicated that, despite the many advantages of such a service, more effort needs to be made to tackle the barriers to its successful implementation and to raise public awareness of the proposed service within the UAE community
The Legend of Orpheus between the narrative and religious presence: the poem Dar Jeddi by Al-Sayab model
The research provides a knowledge reading of one of the most important Greek legends, the legend of Orpheus, and the way it is used within the poetic construction of the Arabic poem. The use of this myth has varied among poets, but Badr Shaker al-Sayyab can be one of the poets who presented the legend of Orpheus in its religious spiritual form and not in its legendary ity, and the poem Dar Jeddi by Al-Sayab was a cognitive achievement to employ the legend of Orpheus through her spiritual discourse, the research will present the integration of the legend in the construction of the poem according to the psychological features and letters of the poet. The researcher relied on the descriptive analytical approach in showing the image of the legend of Orpheus by dividing the research into three main titles, distributed according to the following: the first title: poetry and the reference of the search for truth in legend, in which the researcher presented the meanings of legend and its composition within the literary work. Title 2: The Legend of Orpheus genesis and presence, in which the scholar presented the formation of this myth, and the way it is understood; Title 3: Dar Jeddi\u27s poem between the legendary Orpheus and the spiritual Orpheus, a study and analysis, the researcher was able to read the poem according to the evidence of the Orphe legend, and confirm the presence of this legend from the beginning of the poem to the end
Axial and Lateral Quasi-Static Crushing Behaviour of Segmented and Non-Segmented Composite Tubes
Considerable research interest has been directed towards the use of composite for
crashworthiness applications, because they can be designed to provide impact energy
absorption capabilities which are superior to those of metals when compared on
weight basis. The use of composite circular tubes i n structural applications IS
becoming more widespread throughout the auto motives, aircraft industry.
This work examines the effect of segmentation on the crushing behaviour, energy
absorption and failure mode of composite circular tubes. The segmented composite
tube consists of more than one material, each with its own specific functions.
Through out this study, segmented and non segmented composite tubes with
different sequences were experimentally investigated under axial and lateral loading
conditions. The effect of fibre reinforcement type and segments sequence on energy
absorption and load carrying capacity were also presented and discussed. Load-displacement curves and deformation histories of typical specimens are
presented and discussed. The results showed that non-segmented composite tubes
were found to be very brittle (i.e. tissue mat glass fibre/epoxy tubes), and show very
low initial failure crush load value of 1 .8 9kN, as well as low specific energy
absorption value of O.065kJ/kg under axial crushing. Whereas, the carbon fabric fibre
reinforced plastic (CFRP) tubes showed highest load-carrying capacity among the
tested specimens with initial fai lure crush load value of I8.85kN as well as specific
energy absorption value of I9 .27kJ/kg.
On the other hand, segmented composite tubes including the tissue mat glass fibres
were found to suffer from low energy absorption and the catastrophic failure
mechanism initiated at the part made of tissue mat glass fibre/epoxy. Segmented
Composite tubes from carbon fabric fibre and cotton fabric fibres exhibited good
specific energy absorption value of 13.53 kj/kg as well as stable load-carrying
capacity under axial loading. A change in segmentation sequence affects the crush
loads significantly just for double fibre segmented composite tubes under lateral
loading.
The axial loaded segmented composite tubes have better load carrying capacity and
energy absorption capability compared to the laterally loaded segmented composite
tubes, and the failure modes were quite different
Explicit Solution of the Time Domain Volume Integral Equation Using a Stable Predictor-Corrector Scheme
An explicit marching-on-in-time (MOT) scheme for solving the time domain volume integral equation is presented. The proposed method achieves its stability by employing, at each time step, a corrector scheme, which updates/corrects fields computed by the explicit predictor scheme. The proposedmethod is computationally more efficient when compared to the existing filtering techniques used for the stabilization of explicit MOT schemes. Numerical results presented in this paper demonstrate that the proposed method maintains its stability even when applied to the analysis of electromagnetic wave interactions with electrically large structures meshed using approximately half a million discretization elements
Employee Well-Being During COVID-19 Pandemic: The Role of Adaptability, Work-Family Conflict, and Organizational Response
Well-being has always been a topic of interest for individuals, organizations, and policy-makers. COVID-19 pandemic made it tremendously relevant as employees were forced to work from home due to the successive lockdowns that governments have implemented to curb the spread of the virus. This crisis has raised concerns about employees’ well-being due to the implementation of these tight measures. In the present study, we examined the direct and indirect effects of employees’ adaptability, work-family conflict, and organizational response on employees’ well-being through the mediating role of perceived stress. Data have been collected from 184 employees working in various organizations in Malaysia and analyzed using Smart-PLS Structural Equation Modeling with the bootstrapping procedure. The results indicated that organizational response, work-family conflict, and adaptability directly affect perceived stress and well-being, except for organizational response, which has no direct effect on well-being. Furthermore, it was found that perceived stress mediates the relationship of organizational response and work-family conflict with well-being but not adaptability
Agents of Socialization among Gulf Arab Youth
In the contemporary sense of the term, political socialization in the Arab Gulf is a recent phenomenon. The literature on the area has been essentially of a historical or journalistic nature. Empirical studies of social change, especially in the advent of the oil era, have only begun to appear. This paper will attempt to study some of the causes and consequences of these changes which are unique in many ways. (1) An empirical investigation of the process of socialization will seek to answer some specific questions :
1. What are the agents of socialization?
2. What role do they play in shaping the attitude of the citizen?
3. To what extent have these socialization agents changed and influenced
Arab culture in the drive toward modernity?
4. What is the role of ,the state in promoting some agents over others?
5. Is there evidence of fragmentation in the state?
6. What are some of the orientations of the youth
Turmeric dyeing and chitosan/titanium dioxide nanoparticle colloid finishing of cotton fabric
The possibility of combining the finishing and natural dyeing of cotton fabric has been studied using a single-stage, paddry-cure technique, by treating it with chitosan/titanium dioxide nanoparticle colloids and turmeric dye. Differentparameters have been studied to optimise the process, such as the chitosan/TiO2 nanoparticle colloid concentration, citricacid crosslinker concentration, sodium pyrophosphate catalyst concentration, dye concentration, pH, curing time, andtemperature. To investigate the effects of combined treatment on the dyeing and functional properties of the treated cottonfabric, its ultraviolet protection factor, antibacterial activity, self-cleaning properties, rigidity, colour strength (K/S), fastnessbehaviour, nitrogen content, and wettability are determined. In addition, the cotton fabric surface is characterised usingscanning electron microscopy. The samples treated with chitosan/TiO2 in the presence of citric acid exhibit excellentprotection against ultraviolet radiation as well as antibacterial activity. The optimum conditions are 0.75% TiO2 (w/v), 10% dye (w/v), 2.5% chitosan (w/v), 30 g/L citric acid, 4 g/L sodium pyrophosphate, 70°C drying temp. and 5 min drying time,180°C curing temp. and 2 min curing time. The results also indicate the efficiency of the treatment in improving the selfcleaningproperties of the fabric. A significant improvement in the colour fastness is observed for the treated fabrics
Can plastic waste management be a novel solution in combating the novel Coronavirus (COVID-19)? A short research note
The year 2020 has been noted to be one of major calamity the world over, in which the majority of efforts in research and development have been dedicated towards combating the threat of the novel Coronavirus (COVID-19). Ever since the announcement of COVID-19 as a pandemic, such efforts were dedicated towards the research of its spread and vaccination. Yet still, the world might reach a resolution via an environmental solution that various entities have overlooked, with a plethora of environmental benefits vis-à-vis waste management. In this short communication, the possibility of using plastic solid waste as a substrate to employ copper, and copper alloys and their nanocomposite nanopowders to be used as permanent surface protective coats, is presented. The fact that we present such materials to be of waste origin, is an added value advantage to their beneficial advantage of developing various commodities and products that could be used in our daily lives. Furthermore, the fact that such recyclable materials are susceptible to antiviral properties and chemicals, is an added value that we should not neglect

Fuel Production Using Membrane Reactors
The constant increase in population has led to greater fossil fuel consumption, and subsequently a significant increase in greenhouse gases emission to the atmosphere. This presents a serious threat to the environment and impacts climate change to a great extent. Fossil fuel supplies are depleting fast, and the price of these fuels is also increasing due to their heightened demand. The environmental concerns regarding this are the increased emissions of harmful pollutants
such as carbon dioxide, sulphur dioxide and hydrocarbons. Here we review the alternative fuel technologies which are currently employed to aid the eradication of the current environmental problems. Most notably, this review will demonstrate how membrane reactors are implemented
to improve and intensify the existing renewable fuel production processes. Furthermore, the advantages of membrane reactors when compared to the conventional ones, will be discussed; and the environmental benefits these particular reactors pose will also be highlighted. We will
showcase how these membrane reactors have been applied successfully to improve biodiesel, hydrogen and Fischer-Tropsch synthesis processes. The application of membranes aids the increase in the conversion of desired products, whilst shifting the equilibrium of the reaction
and reducing undesired by-products. Membrane reactors also overcome immiscibility issues that hinder conventional reactor processes. Moreover, they have also demonstrated a significant reduction in the separation and purification of impurities, as they couple them both in one step.
This shows drastic economic and energy requirement reductions in the amount of wastewater treatment associated with conventional fuel production reactor
