Effect of Nursing Care Protocol on Nurses' Competency regards Children with Thalassemia
No full textAbstract: Thalassemia is estimated to affect one thousand children out of every 1.5 million live births in Egypt. Aim: This study aimed to evaluate the effect of nursing care protocol on nurses' knowledge and practice provided to children with thalassemia. Design: A quasi-experimental (pre, post, and follow-up test) was used. Setting: This study was conducted in Pediatric Department at El Menoufia University Hospital, Egypt. Sample: A purposive 35 pediatric nurses providing care to children with thalassemia. Instruments: A structured interview questionnaire to assess nurses’ knowledge about thalassemia and an observational checklist to assess nurses’ practice provided to children with thalassemia. Results: A highly statistically significant difference was found between pre and post-tests and between post and follow-up tests. It noted that none of the studied nurses had competent nursing practice on the pre-test. Meanwhile, all of them (100%) had competent nursing practice on post-test. Also, a highly statistically significant positive correlation between total knowledge and total practice score. Conclusion: Nurses who received nursing care protocol had a higher level of knowledge and practice on post and follow-up tests compared to the pre-test. Recommendations: Continuous training program for developing nurses' knowledge and practices regarding nursing care protocol of thalassemia.

Comparison of Different Optimization Techniques in Electron Lens Design
No full textTo design electron lens systems, applying a fully automated optimization routine has not yet been feasible, especially for the case where the optimization has many free variables of the lens system, such as all parameters that define the geometry of the lens electrodes and the voltage of each electrode. Hence, the study of the implementation of different optimization procedures has not yet been possible either. In one of our previous studies, we have proposed to use the so-called Second Order Electrode Method (SOEM) which performs the electrostatic field calculations in a very short time by the approximations of the field near the optical axis. There, using SOEM in field calculation, a Genetic Algorithm (GA) was successfully implemented to optimize the electron lens systems. One of the questions that has not been studied and answered in the literature yet, is whether the GA is the most suitable option among different optimization techniques for the design/optimization of electron lens systems. In this paper, by implementing the SOEM technique as the field calculation method, different optimization procedures are implemented and their performances are compared. For this study, a typical six electrode lens system is employed. The implemented optimization techniques include calculus-based local optimization (‘Fmin’) and metaheuristic methods such as GA, Particle Swarm Optimization (PSO), and Simulated Annealing (SA). The results demonstrate that the population-based global optimization techniques like GA and PSO significantly outperform single-based local optimization methods such as ‘Fmin’ and SA. Additionally, PSO shows slightly better performance than GA, although it cannot be concluded that PSO will always outperform GA for every electron lens design problem. Furthermore, in the comparison between the two single-based optimization techniques, the metaheuristic approach (SA) outperforms the calculus-based one (‘Fmin’). Hence, we recommend implementing metaheuristic, global, population-based optimization techniques like GA and PSO for the optimization electron lens systems.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Hagen groupHigh Voltage Technology GroupImPhys/Hoogenboom grou
<i>Report:</i> Globalization of Economic Activity: Issues for Tourism
No full text Economic activity is not only becoming more internationalized, but, more significantly, it is becoming increasingly globalized. Globalization is always regarded as the product of the liberalization that has been the hallmark of economic policy throughout the world during the past decade. It has also set in motion forces working to accelerate liberalization. One of the distinguishing features of trade at the end of the twentieth century and at the start of the new millennium has been the expansion of regional trade agreements and the multilateral agreements. The internationalization of services is at the core of today's economic globalization. Tourism has become one of the most important industries in the world, and its economic impacts are vital for many countries. It has long supported the idea of services agreements and has become a major component in the globalization of international trade, particularly with respect to services. There is no doubt that the World Trade Organization (WTO) and the General Agreement on Trade in Services (GATS) have assisted the growth of international trade in goods and services. However, the success of such instruments relies upon markets behaving in a Ricardian manner, incorporating the fluidity and transparency that form the substance of those markets. </jats:p
Globalization of Air Transport: The Challenges of the GATS
No full text The impacts of globalization on national and international policy making processes are illustrated by an examination of the effects on air transport industries. Trends towards the liberalization of air transport activities have been noted in many countries, mainly, to date, those of developed or rapidly developing status. Specific demand and supply conditions affect the air transport industries, and a particular regulatory framework has grown up since the 1940s. The study examines trends towards the privatization of airline companies in the context of (a) the development of so-called global ‘alliances’ or ‘partnerships’ and (b) liberalization at regional level and within trade groups such as the European Union. The new challenges of the General Agreement on Trade in Services (GATS) are considered, especially in terms of how developing countries can develop appropriate policies in response to the forces of globalization, increasing liberalization and competition. </jats:p
Local versus Global Optimization of Electron Lens System Design
No full textIn electron optics, the design of electron lens systems is still a challenge. To optimize such systems, the objective function which should be calculated, depends on the electric potential distribution in the space created by the lenses. To obtain the electric potential, the existing methods are generally based on some mathematical techniques which need to mesh the space of the lens system and derive the electric potential at all mesh points. Hence, calculation of the objective function for such systems are computationally expensive. Therefore, applying a fully automatic optimization routine has not yet been feasible, especially for lens systems with many free variables. Hence, the study of objective-function landscape of such problems has not yet been performed. One of the questions of interest for optical designers, that has not been studied in the literature, is whether this problem can be solved by a local optimizer or is it necessary to apply a global optimizer. Recently we succeeded in implementing a method (based on a so-called SOEM (Second Order Electrode Method) technique) which calculates the electric potential in a fast and reasonably accurate way. In this paper, that method, is implemented to perform the study of local versus global optimization for electron lens design. The global optimization method here is performed by GA (Genetic Algorithm). The objective function is taken to be the probe size of the electron beams at the image plane. The results of our study show that the objective function of this problem has many local minima and the optimization of such problems cannot be handled by a local optimizer. GA is shown to perform well by overcoming these multiple-local minima to arrive at a global minima.Virtual/online event due to COVID-19 Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Microscopy Instrumentation & TechniquesDC systems, Energy conversion & Storag
The impact of Gats: a case study of tourism development in Egypt.
No full textEconomic activity is becoming not only more internationalised, but, more significantly, it is becoming increasingly globalised. Globalisation is always regarded as a product of the liberalisation that has been the hallmark of economic policy throughout the world during the past two decades. Globalisation and liberalisation feed off each other and the former has certainly set in motion forces
working to accelerate liberalisation. Both globalisation and liberalisation have increased the potential for international trade to further establish itself as an engine of growth and an important mechanism for integrating countries into the global economy. Tourism is not only the dominant service in world trade, it has also become one of
the most important industries in the world and its economic impacts are vital for many countries. The tourism industry has long supported the idea of services agreements and has become a major force of the globalisation of international trade, particularly in services. The significance of tourism as a source of income and employment and as a major factor in the balance of payments for many countries has
been attracting increasing attention. Governments, private sector entities, regional and local authorities, and others with an interest in international trade and economic
development have recognised the role to be played by tourism. If the barriers to worldwide travel were eliminated or reduced substantially, international trade in
tourism services is likely to increase dramatically.
The globalisation of production and the liberalisation of trade offer opportunities for all countries and enable developing countries to play a more active role in the world
economy. However, these newfound opportunities do not come without a price and this is to be found in the increasing complexity associated with interdependence including instability and marginalisation. Therefore, the net result is one of trade off between economic gains and costs.
The World Trade Organisation (WTO) is the only international body dealing with the rules of trade between nations. At its heart are the WTO agreements, negotiated and
signed by the bulk of the trading nations of the world. Its main functions, as defined in article III of the Agreement, are to facilitate the implementation, administration
and operation of the Uruguay Round Agreements (GATT, GATS, TRIPS, act) and to provide a forum for negotiations among members. The WTO's overriding objective is to help trade flow smoothly, freely, fairly and predictably. There is no doubt that the WTO and the GATS have assisted the growth of
international trade in goods and services. However, the success of such instruments relies upon markets behaving in a Ricardian manner incorporating the fluidity and
transparency that form the substance of those markets.
The purpose of this research is, through analysis, to gain insight into the impacts of liberalisation brought about by the GATS on tourism development in Egypt and to explore stakeholders' perceptions of tourism liberalisation. This research aims to analyse the terms, codes and practice of the WTO and the GATS and their implications for the tourism sector. This examination is intended to enhance
understanding of how the General Agreement is intended to work and how it may help governments exploit the system to their own advantage, especially in the developing countries.
The research has five broad objectives. The first is to evaluate the level of openness in Egypt's trade in services in general and tourism in particular. The second is to
examine and display the main features of Egypt's GATS commitments. Third, is to explore whether the macroeconomic environment offers the necessary conditions for tourism liberalisation and for private business development (foreign and local alike). Fourth, to determine whether the institutional climate is amenable to the growth and
competitiveness of private firms. Finally, to evaluate the potential impacts of GATS on tourism development in Egypt. This research also has the objective of developing
policy options that embrace and reflect all the major relevant concepts of tourism liberalisation. There are likely to be transitional impacts of trade liberalisation through WTO and GATS. The World Bank (2000) states that globalisation and liberalisation do not benefit everyone equally. Developing countries and the least developing countries are always the least able to take advantage of the opportunities that GATS presents, and globalisation and liberalisation may lead to an increase in inequality in these countries. The future of tourism development in Egypt, as well as the ability of Egypt to integrate successfully into the global trading system will depend upon its ability to strengthen its capacity to produce internationally competitive services and upon the extent of liberalisation in the services sectors in general and the tourism sector in particular. In today's globalised market, a country competes with every other destination in the
type and price of tourism it offers. The main findings of this research indicate that if Egypt is to be successful in competing in the international tourism market, standards
of excellence must be introduced for its products, particularly for infrastructure and accommodation and services. Management and administration of the sector must
improve. Governments must shift to policies that encourage tourism. For example, the sector cannot develop without improvements in public health and personal safety in tourist areas. Air policies that support ease of access and traffic growth are also critical. Governments must also invest in expanded human resource development and institutional capacity building, and improve environmental mitigation and protection. The value to the final consumer is determined by the quality of all these components of the tourism package. Given its cross-sectoral nature, tourism will only develop in a sustainable manner if it is integrated into the country's overall policies and economic and physical planning mechanisms and if linkages are created across the many sectors spanned by tourism. Partial policy measures will be inadequate to address vested interests, underlying economic relationships and generic social or physical constraints. The creation of highly competitive products through good management of natural
and built tourist assets is most likely to convince the international industry to promote one country over another in the global market place. Countries can influence these external industry managers through an effective and continuing promotion and marketing campaign, but will be successful only if there is a highquality, competitive product to sell that competes in value and not just price.
It is hoped that these findings, which offer an understanding of the impacts of GATS and WTO on tourism development, may help address national and regional tourism
development policy-making and strategies in developing countries
NUMERICAL AND EXPERIMENTAL INVESTIGATION ON THE EFFECT OF RESTRICTION SHAPE ON CHARACTERISTICS OF AIRFLOW IN A SQUARE DUCT
No full text Experimental and numerical investigation has been under taken to study turbulent flow of air through duct using restriction in different shapes and positions for Reynolds numbers ranges of (8.2x104 → 5.6x104).The numerical approach used in this work is the finite volume method for solution of elliptic partial differential equation for the modeling of turbulent (k-) model as well as wall function concept near the wall which was used to take the turbulent effects into consideration have been employed.The experimental test rigs were constructed from Perspex, and a fivehole pressure probe was used to measure the three component of air flow velocity vector in space.The results show that the total pressure drop depends on the shape and position of the restriction, and the pressure drop coefficient due to the restriction shape and position (kR) depends on two parameters; blockage area ratio (Ab) and the ratio between wetted perimeter to the free remainder perimeter (pe/Pe) and dose not depend on the Reynolds number ( for the same blockage area ratio Ab if the pe/Pe increases 40%, the coefficient kR increases 7% , and for the same pe/Pe, if the blockage area ratio increases 50% ,the coefficient kR increases 10%). But the pressure drop coefficient due to the friction (Cf) is a function of Reynolds.
