Individual iso-α-acids that are responsible for the bitter taste of beer need to be isolated because these acids are required as reference standards in quantitative analysis and when studying the parameters which effect the quality of beer. However, these pure compounds are very expensive, due to inefficient isolation methods. In this study a new

This study was conducted to investigate the effect of preheating through inductive heating mechanism in end milling of AISI D2 hardened steel (60-62 HRC) by using coated carbide tool inserts. Apart from preheating, two other machining parameters such as cutting speed and feed were varied while the depth of cut constant was kept constant. Tool wear

Emotion perception similar to thinking, learning and remembering is consequent of complicated brain processes which are related to specific biological metabolism. Different human’s emotional states are recognizable by measuring and interpreting of human physiological signals. Bio-sensors possess a number of advantages against other emotion recogn

We have developed one approach to fingerprint and estimate the active compounds in the leaves of Vitex trifolia Linn possessing anti-tracheospasmolytic assay using two-dimensional TLC pattern comparison. Based on the two-dimensional TLC pattern and the activity of the centrifugal partition chromatography fractions, we concluded that the semi polar

This paper presents an EEG-based emotion recognition system using self-organizing map for boundary detection. Features from EEG signals are classified by considering the subjects’ emotional responses using scores from SAM questionnaire. The selection of appropriate threshold levels for arousal and valence is critical to the performance of the rec

Aims: To present findings on low blood vitamin D status and its association with obesity among primary school children in Kuala Lumpur. Methods: A cross-sectional study of primary aged school children was undertaken in 2008. Six primary schools were randomly selected from a zone in Kuala Lumpur with a multi-ethnic population from middle income leve

This paper investigates and presents conditions that guarantee disturbance decoupled fault reconstruction using sliding mode observers, which are less stringent than those of previous work, and show that disturbance reconstruction is not necessary. An aircraft model validates the ideas proposed in this paper.

One important feature of Islamophobia is to caricature Islam as misogynistic and oppressive to women and thus to advance imperialist hegemony. This “gendered Islamophobia” stigmatizes the religion even though, compared to other world religions, its treatment of women is arguably preferable and more enlightened. Historically, one treasonous use

Key Performance Indicators (KPIs) is an example of private sector practices developed and implemented in public sector organizations to improve the performance of public services delivery to its optimum level. This paper proposes a case study on one Local Governments (LGs) in Malaysia to investigate the organizational changes through the developmen
