The decline in freshwater availability has spurred research into employing solar desalination technology. Recent research has concentrated on investigating the use of surface modification to improve the productivity of solar still for desalination. This paper presents the use of femtosecond laser texturing to induce a porous surface on the polymeth

Refurbishment is one of the solutions to address the environmental issues the construction industry faces. However, even though many existing buildings have gone through refurbishment, many buildings still lack consideration to incorporate sustainable elements. Realizing that sustainable refurbishment is one of many ways to solve environmental prob

Sukuk market has hitherto focused on issuances based on intangible underlying assets. Right (haqq) is intangible in nature which can in principle include government awards, goodwill, trademarks, receivables and other related rights as applied in the Islamic capital markets. This paper looks into the opinions of classical Muslim schools and scholars

Zero was a brilliant innovation and most significant achievement but it has threatened the foundations of modern physics and is behind all of the big puzzles in physics. Today, zero lies at the heart of one of the biggest scientific controversies of all time. The mysterious zero is posing challenges not only to intellectuals, philosophers, scientis

The problem of mitigating narrowband interference (NBI) due to coexistence between Digital Video Broadcasting-Terrestrial (DVB-T) and International Mobile Telecommunication-Advanced (IMT-A) system is considered. It is assumed that a spectrum of IMT-A system between 790-862 MHz interfere the spectrum of the OFDM signal in DVB-T band. Two types of co

Carbon fibre reinforced plastic (CFRP) is a composite which has the best strength to weight ratio among the construction materials. It becomes valuable as the demand for this composite has increased dramatically especially in automobile and aerospace industry. Cutting speed of 160–194 m/min and a feed rate of 0.14–0.225 mm/tooth on solid uncoat

As new technologies evolve, new demands are created for protective coatings which are required to have stability over a range of quite aggressive service conditions. For instance, the surfaces of shafts, bearings and steam turbine blades for use in turbine engines are to be protected against daunting effect of high-temperature dry sliding wear. Und

Hardsurface layer was developed by tungsten inert gas (TIG) surface melting on AISI 4340 alloy steel with pre-placed TiC powder and energy input of 1344 J/mm in an argon gas environment. The composite coating layer was produced using an 80 A current, 35 volts potential difference and with a traversing speed reaching 1 mm /sec. The developed hardsur

Dual and multi-band rectangular microstrip antennas can be realized by cutting U slots inside the patch. In this paper, the length and width of U-slots are optimized in order to achieve dual-band and multi-band. Computer Simulation Technology (CST) software was used to design, simulate and optimization of antenna. Two resonant frequencies at 1.8 GH

After half a century of development, Islamic finance has grown into an industry that is very different from the ideals envisioned by its pioneers. There have been widespread calls for reform, but the direction of this reform has been a subject of great debate. This paper looks at the current state of the Islamic finance, defining where the main iss
