The Relationship between the WES Interventions and the Incidence of Diarrhoea
No full textAccess to clean drinking water and sanitation facilities have a direct positive impact on health through prevention of water-borne diseases, especially diarrhoeal morbidity of children. Lack of WES (Water and Environmental Sanitation) services and poor hygiene practices in Pakistan contribute significantly to the prevalence of diarrhoea, a major cause of infant death and children less than five years of age. The estimates show that about 30 percent of total deaths among children are attributed to diarrhoeal disease [Gallup (2001); UNICEF (2000)], and 4.1 years in life expectancy can be added if water borne diseases are eliminated [Ali and Haq (2003)]. Hence, reduction of diarrhoeal morbidity stands out as an important policy goal, which can ultimately lead to reduction in infant/child mortality. In this paper, we shall examine the relationship of WES interventions with that of the incidence of diarrhoea among children under age 10.
Synthesis of Organic–Inorganic Nanohybrids-Based Polymeric Nanocomposites
No full textOrganic–inorganic nanohybrids-based polymer nanocomposites are made up of two different components, and these hybrids attained great attention over last decades due to their diversified framework and fascinating features. These nanohybrids possess synergistic characteristics of both organic and inorganic substances. Different synthetic routes are used to synthesize these materials with enhanced morphology, tunable features, and fine nanostructures. This chapter focuses on various synthetic routes for fabrication of organic–inorganic-based nanopolymeric composites. Synthetic strategies and protocols of different routes have been described in details. We have also discussed the advantages and limitations of all synthetic methods in details.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.Aerospace Manufacturing Technologie

Performance Analysis of Cloud Computing for Distributed Data Center using Cloud-Sim
No full textCloud Computing, a key enabling technology for speedy wide-area networks are one of the emerging technologies in Computer Science. One of the pressing challenges in the ongoing research in this particular domain is data confidentiality. There is an immense need to preserve important data and confidentiality in cloud computing, which means a more critical requirement for robust mechanisms to protect it from attackers or intruders. This paper proposes a broad and thorough probing multiple simulation-based software that examines and evaluates the execution, extensibility, strength, and intricacy of Cloud data center. This paper analyzes different Cloud services using Cloud-Sim, Cloud Analyst, and OPNET simulation tool. Services, cloud management, load-distributing, cloud strength, and expand-ability are the main scope of this paper. Hence, results are compared in the real-time framework to identify the performance and extensibility, as well as consider the experiment as challenges for further discussion
On-body antennas: Design considerations and challenges
No full textThis paper highlights the considerations and challenges when designing antennas suitable for on-body communication in Wireless Body Area Networks. Designing antennas that are required to operate in near body scenario make it more challenging for antenna designers as several important factors need to be taken into consideration along with the human body effects. These factors include antenna detuning, impedance matching, radiation pattern, Specific Absorption Rate, size, cost, weight, positioning, bending and stable performance with the variation of the gap between the antenna and the human body. An antenna addressing these challenges is suitable for on-body communication and wearable application
Comparison of direct–indirect emissions of conventional and advanced technologies in European aviation
No full textThis research aims to investigate and compare new and existing technologies and their impact on overall emissions during climb, cruise, and descent (CCD). The data is obtained from the International Civil Aviation Organization (ICAO) and the European Environmental Agency related to fuel flow rates, types of aircraft and engines, and emission factors. Based on the data obtained, the nitrogen oxide (NOx), carbon monoxide (CO), and hydrocarbon (HC) emissions of each aircraft are carefully analyzed to estimate accurately their impact on the environment. The developed fuel flow model considers various factors to estimate the fuel consumption of selected aircraft and provide a comprehensive understanding of the environmental influence of each aircraft. The findings of the study reveal that in scope 1, traditional aircraft generate 27% higher emissions than biofuel-powered (100% blend with Jet-A1 fuel) aircraft, and this disparity increases to 31.4% when compared to hybrid electric aircraft. The analysis shows that electric aircraft emissions are 85.1% lower than conventional aircraft. Furthermore, it is estimated that in the majority of instances involving the chosen aircraft, the levels of NOx emissions are consistently greater in comparison to HC. Further, this study offers valuable insights to policymakers and regulators in their efforts to develop more effective emission regulations and incentives for the aviation industry, particularly concerning CCD emissions. It also provides a comparison of the top 10 European airports that are responsible for the highest emissions in Europe based on the data provided by OAG. In general, the results of this study possess the capacity to stimulate innovation and facilitate the advancement of environmentally friendly aircraft technology within Europe. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025
Fracture toughness and failure mechanism of high performance concrete incorporating carbon nanotubes
No full textCement and concrete composites are inherently brittle and exhibit very less tensile/flexural strength capacity as compared to their compressive strength. Use of thoroughly dispersed carbon nanotubes in the concrete matrix is one of the possible solution for enhancing mechanical properties in tension/flexure. In the present research work, small fractions of multiwall carbon nanotube (MWCNTs) i.e. 0.05 and 0.10 wt% of cement have been integrated into the cement concrete to study their effect on the mechanical properties of the resultant concrete mixtures. The enhanced performance of the whole mix lies on a single point that MWCNTs must be thoroughly disperse in the mixture. Hence, special arrangement through usage of high energy sonication along with amended acrylic based polymer (performing as a surfactant) was made to have a uniform dispersion of MWCNTs in the concrete mix. The testing of concrete samples includes i.e., flexure, splitting tensile and compressive strengths after 3, 7, 28 and 56 days of curing. After having comparison with the control mix cured for 28 days, it was observed that the addition of 0.05 wt% MWCNTs increased the splitting tensile strength by 20.58%, flexural strength by 26.29% and compressive strength by 15.60%. Through above results, which verify the increase in concrete mix strength after adding MWCNTs, these MWCNTs may be incorporated in the treatment of Nano/micro cracks completed through process of connecting, branching and pinning. Similarly, as proved in threepoint bending tests, MWCNTs also enhances the breaking strains as well as the fracture energy of the concrete mixes, besides, imparting increase to the strength. The investigations have shown that incorporating lesser amounts of MWCNTs i.e., 0.05 and 0.10 wt% of cement to the concrete mixes after insuring there complete dispersion, unusually improve their properties like mechanical strengths and fracture behavio
