Experimental Mechanical Characterization of Silica Fume-based No-fines Concrete Reinforced by Steel or Nylon Fibers

Aims: In this study, the mechanical characterization of no-fines concrete solutions is addressed experimentally, with the purpose of possibly increasing their strength by using silica fume and embedded fibers (steel and nylon fibers) as possible efficient reinforcement. Background: Due to competition between developed and advanced countries, the contemporary construction sector is currently experiencing a shortage of fundamental building materials. In this regard, no-fines concrete is becoming increasingly popular, and it has been proven in the literature that it can offer some advantages as an economic and lightweight solution compared to conventional concrete. However, experiments and investigations are still needed to investigate the potential mechanical advantages for its efficient use in buildings, given that the major limitation compared to normal concrete is represented by limited strength. Objective: The primary objective of the present study is to assess the mechanical strength of no-fines concrete samples in which steel fibers, nylon fibers, and partial cement replacement with silica fume are used. For this purpose, no-fines concrete specimens are produced with fixed mix proportions of 1:6 cement-aggregate (c-a) ratio, various coarse aggregate gradations ((20-10) mm and (10-5) mm), and fixed w/c ratio (0.42). Methods: The experiments are carried out on cubes, cylinders and prisms of concrete samples with various aggregate solutions. The nominal length of both types of fibers is fixed at 20 mm. Steel fibers with 1 mm in diameter and nylon fibers with 0.3 mm, 0.4 mm, 0.5 mm, or 0.6 mm diameters, respectively, are taken into account to explore their effects on compressive strength, split tensile strength, and flexural strength. Results: The presented experimental results showed various mechanical advantages, such as increased compressive, splitting tensile and flexural strength parameters, for most of the examined samples. Nylon fibers, in particular, proved to significantly increase compressive, splitting tensile, and flexural strength values, compared to normal concrete, with additional benefits compared to steel fibers (for the examined arrangements and configurations). Conclusion: Overall, the examined compositions and mixtures of silica fume-based no-fines concrete samples encourage further investigations for the optimization of these solutions. In this regard, in addition to mechanical capacities, further key parameters (such as weight, cost, impact on concrete microstructure, etc.) will be taken into account

Assessment of active pharmaceutical ingredients in drug registration procedures in Pakistan : implications for the future

Introduction: There are concerns over the quality of generic medicines in Pakistan. This is due to perceived non-compliance with good manufacturing practice (GMP), whereby the quality of the raw materials is not being assessed. If not addressed, this will impact on the potential for generics exports from Pakistan, as well as on patient care. Consequently, there is a need to assess the current assessment and regulatory situation in Pakistan and to recommend a way forward that ensures the future quality of products. Objective: To assess the quality of the raw materials that are either imported to, or manufactured in Pakistan, that are then used to produce a leading analgesic (ibuprofen). As part of the assessment, the presence and levels of impurities will be determined. Subsequently, the findings will be used to recommend potential regulatory changes to improve patient care. Methods: The quality of 27 sourced raw materials and the reference product were assessed using a variety of quality assessment methodologies, including assay tests, and infrared spectroscopy and UV-spectrophotometry. The calculated values were then compared to values documented in the Certificate of Analysis (CoA), and high performance liquid chromatography (HPLC). Results: All but one sample passed the spectroscopy identification tests. However, 81.5% of samples failed to comply with pharmacopoeia assay limits. There were also concerns with the use of HPLC methods used to assess the quality of raw materials, and over the fact that assay values obtained were not the same as those listed in the CoA. In addition, where manufacturers had concerns over the amount of ibuprofen in the raw material, rather than rejecting the product, they typically used higher quantities to make up any shortfall. Conclusions: The results of this study demonstrate that there is an urgent need to improve the registration process for generic products in Pakistan. This should include implementing Common Technical Documents (CTDs) based on international standards. In this way, we will see generics being produced that result in improved patient care and that have potential for export from Pakistan

Privacy and security challenges in smart and sustainable mobility

The current era of computing is witnessing a huge amount of data being generated with every passing moment. This massive data if nourished efectively can open new horizons for the computing world. The modern world is slowly but surely moving towards the automation age where every entity and object is being automated to perform desired tasks without the need of human interventions. This has made the lives of people more convenient and comfortable. Automation has taken over every single feld of computing and even beyond. Smart mobility is one such example of automation wherein the users get real time information about the trafc conditions as well as alternate route suggestions in case of trafic jams. Transportation is considered as the backbone of every business. The automated intelligent transportation system (ITS) has completely transformed the way how people, goods and services are transported and is quite important for achieving sustainability. This paper provides an overview of the existing ITS system, concept of smart mobility and existing vulnerabilities in these systems. Their security concerns and scenarios are also analyzed. Furthermore, in this paper the importance and need for securing these intelligent systems is highlighted and future trends in ITS is also suggested. Although ITS and smart mobility technology are already providing convenient transportation and navigational facilities, there is still a huge scope to improve these facilities for the end users. The suggested future trends if integrated in an efective manner can provide exemplary means to provide state-of-the-art navigational facilities and smart mobility in a true sense.5311-8814-F0ED | Sara Maria da Cruz Maia de Oliveira PaivaN/

Techno-Economic Feasibility Analysis of Concentrated Solar Thermal Power Plants as Dispatchable Renewable Energy Resource of Pakistan: A case study of Tharparkar

Pakistan is identified to be one of the next-11 the top emerging economies of the world after the BRICS. This emphasizes the establishment of a competitive electricity market that can fulfil the demand of the country considering the environmental concerns. In this scenario reliability of power is something that cannot be compromised. Dispatchable power stations play a major role in balancing supply and demand; this balance is essential for maintaining the power cuts free country. All dispatchable power stations incorporate some form of storage particularly thermal or chemical (i.e. a stored fuel).  Earlier dispatchable power was regarded as the generation which can start quickly and meet the peak demand requirements but arrival of renewables in power system has increased worth of its presence since it has just not to supply peak demand but also to meet during the unavailability of other renewable energy sources because of their intermittent behavior meanly at times of dark hours and slow wind speed. This study considers the viability of Concentrated Solar Thermal Power in Pakistan and thoroughly analyses several characteristics i.e., Availability of fuel, water, road and communication network, flexibility and environmental impacts of the technology for the cite of Tharparkar
