Supercritical fluid extraction (SFE) of Pereskia bleo leaves was carried out with systematic experimental study to screen and optimize the factors affecting yield and antioxidant activity. Initially, five factors were studied by Plackett–Burman study to screen the most influential factors. Consequently, three significantly affecting factors were

Quantum cryptographic protocols solve the longstanding problem of distributing a shared secret string to two distant users by typically making use of one-way quantum channel. However, alternative protocols exploiting two-way quantum channel have been proposed for the same goal and with potential advantages. Here, we overview a security proof for tw

Multivariate analysis of thin-layer chromatography (TLC) images was modeled to predict antioxidant activity of Pereskia bleo leaves and to identify the contributing compounds of the activity. TLC was developed in optimized mobile phase using the 'PRISMA' optimization method and the image was then converted to wavelet signals and imported fo

Sedarkah anda, bahawa kita semua adalah “Perokok”? Apa perlu dilakukan? Adakah anda merasakan jumlah perokok di dunia umumnya dan di Malaysia khususnya semakin berkurangan? Adakah anda yakin bahawa masyarakat dunia semakin sedar akan bahaya merokok? Anda yakin usaha mengekang gejala merokok sangat berkesan? Adakah anda rasa duduk di rumah masih

This paper presents the effect of Jatropha curcas biodiesel on the wear properties of mild steel, which was coated by preplacement of TiC particulate and melting it using a conventional TIG torch arc heat source. The aim of the study is to investigate the wear behaviour of surface modified AISI 4340 steel and the uncoated AISI 4340 steel which were

Itu antara keluhan dan pertanyaan yang sering diungkapkan oleh para ibu bapa, mahupun pesakit itu sendiri apabila keadaan kulit mereka masih tidak sembuh sepenuhnya dalam tempoh masa yang diharapkan. Lebih tepat lagi, ianya seringkali diutarakan oleh pesakit-pesakit kulit kronik seperti eczema ketika mendapatkan rawatan di klinik pakar kulit mahupu

Food ingredients derived from plants are a rich source of polyphenols. In recent times, polyphenols have become popular for their therapeutic properties as antioxidants. 6-gingerol, the main bioactive phenolic compound in Zingiber officinale, is well known for its free radical scavenging capabilities in treating multiple ailments. The most common m

Waste materials (tailings) generated from mining processes contain significant amounts of palladium, which are considered uneconomical to be extracted using conventional methods. Studies have demonstrated that Arabidopsis thaliana (Arabidopsis) can accumulate palladium as nanoparticles in the plant tissues. In collaboration with the Green Chemistry

Diabetes has been one of the top ten causes of death in Malaysia. Recently, the oil palm Elaeis guineensis has been explored in several antidiabetic studies. Nevertheless, the oil palm fruit has never been investigated for its antidiabetic effect. Therefore, this study was conducted to evaluate the antidiabetic properties of oil palm fruit which sp

Human hand functions range from precise-minute handling to heavy and robust movements. Remarkably, 50 percent of all hand functions are made possible by the thumb. Therefore, developing an artificial thumb which can mimic the actions of a real thumb precisely is a major achievement. Despite many efforts dedicated to this area of research, control o
