In this paper we investigate the azimuthal pattern symmetry of an Archimedean spiral antenna which is designed to operate over the frequency range 3-10 GHz. The performance of the spiral in free space is compared with a structure that is backed by a perfect electric conductor with a separation distance of λ/4 at the operating frequencies. The latt

Several marine diatoms have been known for their high lipid content. Chaetoceros is the largest genus of marine planktonic diatoms with approximately 400 species described. Lipid is important as primary storage for nutrient and essential for cell's growth and function. Nowdays, there are increasing in demands for alternative source of fuel with

Actinomycetes are renowned as a rich source of bioactive molecules. However, the commercially potent secondary metabolites from well-known actinomycetes are difficult to discover due to the practice of screening that is leading to rediscovery of known bioactive compounds, thereby, emphasizing the need to isolate undiscovered actinomycetes. Mangrove

Psychrophilic organisms produce enzymes adapted to function at low temperature. These enzymes are characterized by a catalytic efficiency at low and moderate temperatures but are rather thermolabile. Thermophilic enzymes usually feature in discussion of industrial uses because their heat-stability makes them ideal biocatalyst for many reactions. Ho

Education is more than studying for examinations and getting ready for employability and satisfying industry needs. Rather, education now a days incorporates 4Ms (Manpower, Mind, Machine and Market). Education with soul and loaded with values and wisdom can nurture the humanising process that makes individual and professional achieve sustainable de

Abstract: This study aims to examine the influence of the competing values on firm performance mediated by diverse performance measurement system. With a different focus to that of Henri’s (2006) concept of dominant culture, we argue that in control dominant firms, flexibility and diverse performance measures (PM) can lead to improved performance

Strata living brings people of diverse interests, different cultures, values, ages and backgrounds under one roof. With that background, it is usual to have differences and disputes. While many would generally believe that problems can be resolved by prople involved talking about their problems and fulfilling their expected responsibilities, more o

Dye-sensitized solar cells (DSSCs) were constructed by using the Lawsonia inermis leaves, Sumac/Rhus fruits, and Curcuma longa roots as natural sensitizers of anatase-based nanostructure TiO2 thin film Paint-coated on ITO conducting glass. The orange-red Lawsone, red purple anthocyanin and yellow Curcumin are the main components in the natural dyes

Modern man is in search of spiritual solace to help relieve him of his mundane problems. In his search for such comfort he tends to land himself in the snare of some misguided spiritual claimants, who are packing religion to suit the person. Thus some are advancing the idea of segregation between the three fundamentals of Islam: iman, Islam and ihs

The Malaysia National Library (PNM) was established in 1966 as a unit of the National Archives of Malaysia. Today PNM is a Division under the Ministry of Information, communications and Culture. PNM plays a significant role in collecting, processing, disseminating, storing and utilizing knowledge. This role is parallel with the aspiration of Malays
