The use of computer-based tools and methods in the development process is essential respectively quality, time and costs. Meanwhile the general business conditions are similar worldwide: product life cycles decline drastically and technological leadership of the highest possible quality is required in order to react to constantly increasing innovation dynamics. Engineers have to decrease the ti...

Curcuma ochrorhiza ('temu putih') and C. heyneana ('temu giring') are two Zingiberaceous species which are commonly used in traditional medicine in Malaysia and Indonesia. Phytochemical investigations on these Curcuma species have resulted in the isolation of six sesquiterpenes, namely zerumbone (1), furanodienone (2), zederone (3), oxycurcumenol epoxide (4), curcumenol (5) and isocurcumenol (6...

The accumulative partitioning of Pb and Cu in the Rhizophora apiculata was studied randomly in the Setiu mangrove forest, Terengganu. Samples of leaves, barks and roots were collected randomly from the selected studied species. Sediments between the roots of the sampled mangrove plants were also collected. The results from analysis for Rhizophora apiculata shows that the concentration of Pb and...

The effect of heat-dispersing on sticky substances in a deinking pulping line was studied under different conditions including varying temperature, disc clearance, and pulp consistency. Sticky substances were quantitatively investigated before and after the heat-dispersing, and categorized into macro-, mini-, and micro-stickies as well as dissolved and colloidal substances. Meanwhile, their ext...

OBJECTIVE This study aimed to assess adherence and knowledge of manicures/pedicures on the use of Personal Protective Equipment (PPE). METHODS It was a survey with 235 manicures/pedicures in salons, Belo Horizonte/Brazil. Data were analyzed with the software Statistical package for the social sciences (17.0), using descriptive statistics, chi-square and logistic regression. RESULTS The adhe...

The complex and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the nano structured films had particle size in the range of 28 to 34 nm. The energy-dispersive spectroscopy (EDS) showed the existing of carbon in complex-structured amorphous carbon f...

Objective: The purpose of the study was to explore the relationship between hepatitis B virus (HBV) infection and hepatic metastasis in non-small cell lung cancer (NSCLC). Methods: Four hundred and eighty cases of NSCLC were retrospectively analyzed from January 2003 to January 2010, and the prevalence of hepatic metastasis of NSCLC in patients with and without hepatitis B virus infection were ...

Three sulphonic acid-doped polyanilines were synthesized through chemical oxidation at low temperature (0-5 C) and potential of these polymers as sensing agent for O2 gas detection in terms of fluorescence quenching was studied. Sulphuric acid, dodecylbenzene sulphonic acid (DBSA) and camphor sulphonic acid (CSA) were used as doping agents. All polymers obtained were dark green powder. Polymers...
