Eutectic mixtures (EMs) were used for functionalization of carbon nanotubes (CNTs). The process consists of two main steps: a pretreatment with an acidic KMnO4 solution followed by an ultrasound treatment of CNT with the EM as a new class of environmentally-friendly solvents. Various ammonium and phosphonium based-EMs were used in the process and c

Specific odd harmonics can be mitigated by operating the semiconductor switches in H-bridge inverters at optimized switching angles of the PWM signals. These switching angles can be achieved by deriving a set of nonlinear equations using Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM) technique. Modulation index (ma) is a significan

Clay is an inherently occurring material constituted with fined-grained mineral. The minerals are generally less than 2 microns and occur to be plastic in water content which solidify when dried. In the earth surface, clay represents the most available mineral and forms rocks known as shale and is the major component of sedimentary rocks. The small

During pregnancy, increased acidity in the mouth increases the risk of antenatal mother to get dental caries. It is worsen if antenatal mother has morning sickness like vomiting during pregnancy. It can aggravate the problem by exposing the teeth to more gastric acid. In addition, antenatal mothers have hormonal changes that they are more susceptib

This book addresses fundamental components associated within the concept of environmental science. It covers the components of ecosystem, environmental hazards,environmental pollution, natural resources, environmental conservation, sustainable development, urban development control as tool for sustainable development, contribution of natural resour

The Declaration of Alma-Ata in 1978 was the first international declaration supporting primary healthcare as the most important approach in achieving the World Health Organisation (WHO) goal of “Health for All”. The Primary Healthcare (PHC) approach adopted the values of equity, people-centeredness, society participation and autonomy, which was

Introduction: The recommendation to lose weight has been the guiding principle in the treatment of type 2 diabetic patients. However, to facilitate this process, it is vital to understand factors associated with personal feelings about body weight and related behaviour. Methods: The objectives of this cross-sectional study were (1) to determine mea

Ten solvents were used to extract phytochemicals from the peel of Carica papaya cv. Sekaki/Hong Kong to determine their antibacterial activities. Moderate to clear inhibition on Corynebacterium diphtheriae, Streptococcus pneumoniae, Bacillus subtilis and Clostridium perfringens were obtained from the disk diffusion test out of fourteen pathogens te
