A lack of aquatic plants in aquatic ecosystem may suggest a reduced population of wildlife whereas the absence of aquatic plants may indicate problems in water quality. However an overabundance of aquatic plants may due to excessive nutrients, organic or heavy metals interference. Aquatic plants are well known as a good accumulator for heavy metals

Over the past decade, medical tourism has been growing progressively in developing countries of Eastern Europe, South Asia, Southeast Asia, and Middle East. This paper aims to conceptually understand medical tourists’ (or consumers) intentional behaviour to destined countries of their choice within the ‘Halal’ (Permissible) medical tourism se

The awareness towards Shariah compliant concept to be implementing in Hotel sector has been discussed since 1982. An extensive literature and research described variety of approaches and methods to improve the understanding of the concept. Specifically in many of the hotel operations, one of the prior parts is to provide comfortable and affordable

Aquatic plants or macrophytes are beneficial to fresh water bodies because they produce oxygen, which assists with overall fresh water bodies functioning, and provide food and shelter for aquatic living organisms. A lack of aquatic plants in a freshwater bodies system where they are expected to occur may suggest a reduced population of macro and mi

This study aimed at establishing callus cultures as an alternative research tool to study the regulatory mechanisms of the carotenoid biosynthesis in plant through a controlled environment. Previous studies established that selasih or O. basilicum is rich with carotenoids such as neoxanthin, lutein, violaxanthin, α-carotene and ß-carotene. Intere

Abiotic stress factors are the main limitation to plant growth and yield in agriculture. Orange sweet potatoes may become major sources of carotenoids in the diet, but the extent of environmental and genetic influences on plant carotenoid biosynthesis are poorly understood. Carotenoid biosynthesis is regulated by several factors such as water, ligh

Most of developing countries used to develop various technologies to decrease the percentage of heavy metals contaminant from landfill site such as incineration, solvent extraction, soil washing by using physical separation methods or chemical agents, solidification or stabilization technology, indirect thermal treatment, soil venting, membrane tec

The growth of solid waste generation in Malaysia from year 2005 to 2013 statistically has risen from 19,000 tonne to 33,000 tonne per day. This rapid increase mainly affected the number of landfill which is the final disposal destination of solid waste. Landfill is very crucial site which need to be managed properly or it can be hazardous to the li

Phytohormone abscisic acid (ABA) plays a regulatory role in many physiological processes in plants and is regulated and controlled by specific key factors or genes. Different environmental stress conditions such as water, drought, cold, light, and temperature result in increased amounts of ABA. The action of ABA involves modification of gene expres

Colour is one important characteristic to food products as it dictates consumers’ first perception on the foods’ flavour and quality. In the current food industry, most of the colorants used were derived from synthetic sources. However, due to negative health impacts of the synthetic colorants, the urgency to find natural colorants and impose i
