Effect of electrolyte on synergism of anionic-nonionic surfactant mixture

In this study, anionic (Sodium Dodecyl Sulfate) and nonionic (Triton X l00) surfactants mixture (1:1 mass ratio) were evaluated for synergism in Critical Micelle Concentration (CMC) at different ionic strength values. Interaction between the binary surfactant mixture was studied by surface and interfacial tensions. The composition of mixed micelles and the interaction parameter, β evaluated from the CMC data obtained by both surface and interfacial tensions for different systems using Rubingh’ s theory were discussed. It has been shown, that the, micellization behavior of the mixture was improved significantly in presence of salt in particular after equilibration with shale

Sustainable Transportation Modes and Infrastructure

With the aim of achieving a lower carbon footprint on the environment, green technology has been introduced in transportation systems in the past decade. Vehicles powered by renewable energy and smart road plans will need to be utilised. In this hypothetical project, glow-in-the-dark roads, road heating elements, intelligent road lighting system, Urban Maglev, bicycle hire system, electric vehicle charging system and Bus Rapid Transit were proposed for implementation in York, to pioneer an eco-transport city. Problems this project sought to tackle included: bad weather conditions such as flood; snowy and icy roads; road congestion; excessive carbon emission; wastage of clean renewable energy. Public transport services provided through this project will reduce car usage in York, encourage cycling and walking, provide easy access for York residents and visitors, and pioneer renewable energy usage for private vehicles. We advocated the aforementioned solutions based on a review of the literature, case studies, archival research and a survey. As York is a city full of historical structures and with a growing population, factors of both technology and local needs have been integrated to produce a pioneering city in the United Kingdom while advancing the technology growth. As a result, renewable energy is hoped to be used in a much wider context as it would help to pave a healthier and more sustainable future

Compact single-stage input-powered bridge rectifier with boost switch with high output power for energy harvesting system using 0.18-micron CMOS technology / Roskhatijah Radzuan

The demand on microwatt to milliwatts energy harvesting systems has been increasing recently with the increase of the needs for wireless self-powered device applications. With the small output voltage and the AC output from the micro harvesting generators, highly precise specifications, leading to challenging designs, optimizations and realizations of its every component are imposed. Rectifier, which is normally located right after the energy generator in the energy harvesting system, is required to be compact, with high efficiency to produce as high output power as possible. It is in this context that this thesis is focusing, where a new topology of CMOS bridge rectifier is proposed, offering advantages in terms of the compactness and high output power, which is suitable for wireless power devices applications. CMOS technology is seen as a straightforward solution for compactness as it offers possibility to reduce the full wave rectifier circuit size. The proposed rectifier circuit topology is designed such that the threshold voltage, which is a common source of voltage drop in the system, can be reduced, in order to maintain high output voltage

Synthesis Of Light Colour Medium Chain Triglycerides From Palm Kernel Oil Products

The synthesis of light colour medium chain triglycerides (MCTs) from medium chain fatty acids (MCF As) and glycerol was investigated in this study. The production of light colour medium chain triglycerides is tedious and consists of several purification steps. This causes an increase in production cost and its economic viability. In this study, homogeneous catalyst, homogeneous catalysts with an absorbent and heterogeneous catalyst were used in an effort to establish methods to minimise cost. Catalyst was used in order to reduce the reaction temperature, time and produce higher percentage conversion of MCTs, whereas absorbent helps in producing light colour MCTs. The results showed that the use of homogeneous catalyst reduced the temperature and time of the reaction with higher conversion rate of MCTs, but the product obtained was dark in colour. However, with the presence of absorbent, the colour of the product obtained improved tremendously to almost colourless

Vendor managed inventory performance in Malaysian manufacturing companies

The implementation of the Vendor Managed Inventory (VMI) in the Malaysian manufacturing sector can be viewed as a solution to mitigate the increment of operational costs and low performance in customer services. Many factors contributed to the performance of the VMI programme, but only a few attempts were made to determine the contribution of the VMI elements and the organizational factors on VMI performance; and the influence of the types of products in this relationship. The objectives of this study were to determine the relationship and to examine the impact of the VMI elements, the organizational factors on VMI performance, and the moderating effect of the types of products on the relationship between the VMI elements, the organizational factors and VMI performance. The study used the survey method. Data were tested from 101 manufacturing companies listed in the Federation of Malaysian Manufacturers. The findings from the Pearson Correlation test showed that inventory location, managerial commitment, decentralized decision- making, information- system capability and trust have significant and positive relationships with cost performance. Meanwhile, inventory location, demand visibility, inventorycontrol limits, managerial commitment, information- system capability, and trust have significant and positive relationships with service performance. In addition, the multiple regression analysis showed that demand visibility, inventory- control limits, inventory location, trust, and managerial commitment contribute to VMI performance. The hierarchical regression analyses revealed that the types of products have a significant moderating effect to warrant desirable performance from demand visibility, inventory location, inventory control limits, and inventory- ownership. Therefore, the implementation of VMI in the Malaysian manufacturing sector needs to share demand information, apply minimum and maximum limits for inventory control, locate storage locations near customer premises, establish trust, and provide sufficient managerial commitment to benefit from the VMI programme. This study also suggests that the application of inventory- control limits on innovative products would decrease the cost performance of VMI. Also, inventory- ownership by the supplier on functional products would decrease the service performance of VM

A Case Study on the Strategy of Bank Negara Malaysia to Curb Loan Growth

1997 was a challenging year for the con duct of monetary policy. The first quarter of the year saw high levels of monetary growth driven by rapid growth in credit, which had also prevaile d during the most part of 1996. In addition, loans were increasingly channelled towards less productive activities. Such developments raised several concerns. High levels of monetary expansion, if left unchecked, would have inflationary implications on the economy. Furthermore, the rise in loans to the property sector and to stock market-related activities increase d the exposure of banking institutions to these sectors, raising the potential risk to the soundness of the institutions. Given these concerns, Bank Negara Malaysia (BNM) has to introduce strategic measures, to ensure that the stability of the banking system was not undermined by excessive exposure to the relatively more volatile sectors of the economy

Flexural strength of concrete prism strengthened using CFRP with modified mortar

Reinforced concrete (RC) is a good durable material that commonly used in construction compared to others. However, reinforced concrete structures may be damaged and are suffering from various deteriorations because of overloading and an inadequacy of design which may be attributed to cracks, spalling, large deflection, and more. Hence, it is essential to find repair and strengthening techniques of deteriorated concrete structures not only suitable in terms of the economy, but also to use them for their intended service life
