Faculty of Engineering, Universiti Putra Malaysia 43400 UPM, Serdang, Selengor, Malaysia

This paper explains development of a new self-assessment framework according to core values, fundamental principles and requirements of ISO 9001: 2000, and its compiling and validation .The studying activities finally led to developing a new self-assessment model with 33 criteria (key statements), and 300 indicators (focus areas), in 8 separated fundamental principles of ISO 9000 family. Developed model has been applied in 8 Iranian ISO certified companies, and results, analyzed by SPSS 13, suggested that validity of model (content, construct and predictive validity) is approved with Cornbach’s alpha (0.933-0.943).

Chia Chi Sun & Grace T R Lin*





Institute of Technology Management, National Chiao Tung University, Taiwan

Grey theory is an effective method to solve uncertainty problems with discrete data and incomplete information. This paper proposes an improved grey GM (1, 1) model, using a technique that combines residual modification with Markov chain model. Proposed Grey-Markov model, applied as a case study to annual output of Taiwan Hsinchu Industries Science Park, could clearly improve forecast accuracy of original Grey forecast model.

This study presents a new automated system for inspecting markings on surface mounted devices (SMDs) prior to packaging. In proposed design, marking region is identified using a normalized cross-correlation template-matching scheme. A multi-resolution pyramid image processing approach is used to enhance speed of search process. Target image is filtered using a hybrid digital logic filter (DLC) / mean and standard deviation gray scale (MSDGS) algorithm for noise filtering. Individual characters in marking are segmented and fed to a neural network for automatic recognition. DLC / MSDGS filtering scheme is found more straightforward and far more robust toward a noise filtering than conventional image processing schemes. System achieves a recognition rate of 99.14% with identifying each IC chip marking within 0.05 sec. System provides an ideal solution for real-time inspection of IC markings in high-throughput SMD packaging applications.

Silver ion exchanged titania nanotubes for decontamination of 2 chloro ethyl phenyl sulphide and dimethyl methyl phosphonate













G K Prasad*




Defense Research and Development Establishment, Jhansi Road, Gwalior 474 002, India

Decontamination reactions of chemical warfare agent (CWA) simulants (2 chloro ethyl phenyl sulphide and dimethyl methyl phosphonate) on silver ion exchanged titania nanotubes (Ag+-TiO2 NT) were studied by gas chromatography (GC). Nanotubes (NTs) were synthesized using hydrothermal-ion exchange method and characterized by SEM-energy dispersive analysis of X-rays, N2 BET, X-ray diffractometry and thermogravimetry. Formation of hydroxy ethyl phenyl sulphide and methyl phosphonic acid exemplified the role of hydrolysis reactions in decontamination of CWA simulants. Reactions seemed to occur considerably faster on Ag+-TiO2 NT indicating catalysis by Ag+.

This study presents comparative TLC of ethanol extract of plants, Euphorbia hirta L. (Euphorbiaceae) and Gomphrena celosioides Mart. (Amaranthaceae), and formulation (E. hirta + G. celosioides, 4:1) was compared with some of the available homeopathic drugs for piles. Comparative chemo profiling showed that major components, present in homeopathic formulations of piles, were also found in both these plants and their folk remedial combination. Microscopically, E. hirta can be identified due to the presence of various types of simple, multicellular, uniseriate, warty and smooth trichomes and laticifers in traverse section (TS) of root, stem and leaves and G. celosioides due to the presence of long multicellular simple trichomes, anomalous secondary growth and pith in TS of root.

This paper presents authentication and quality evaluation of stem bark of Saraca asoca (Roxb.) Wilde, officially considered as ‘Ashoka’, in comparison with stem barks of S. declinata Linn and Polyalthia longifolia Benth, which are also known as ‘Ashoka’. S. asoka is an important indigenous drugs for treatment of various female disorders. HPTLC profile shows characteristic band under UV 366 nm as follows: S. asoca, Rf 0.53; S. declinata, Rf 0.18; and P. longifolia, Rf 0.13 0.21, 0.27, 0.38, 0.49. Presence of stigmasterol in S. asoca and S. declinata and its b-sitosterol in stem bark of P. longifolia was observed.

Various indigenous strains of Saccharomyces sp. (SCP-1, SCP-3, SCP-4, SCP-5, SCP-7) isolated from datepalm (Phoenix dactylifera) sap were evaluated for alcohol dehydrogenase (ADH) enzyme activity, ethanol production and alcohol tolerance limits and compared with standard culture of S. cerevisiae (S.C.Std). Alcoholic contents in juice samples fermented with different yeast strains varied considerably (8.9-12.5%, v/v) as determined by GLC. Yeast cultures showed varied in vitro ethanol tolerance (3-12%). Isolate SCP-1 was found superior showing 12.5% ethanol production, high ADH enzyme activity (4.38 units/ml) and higher alcohol tolerance maintaining cell viability at 12% ethanol in YPD medium up to 48 h.

This study presents adsorption performances for Carbamazepine, Propyphenazone, and Sulfamethoxazole using polymer resin, Lewatit VP OC 1163. Adsorption capacities followed: Carbamazepine> Sulfamethoxazole> Propyphenazone. Lewatit VP OC 1163 showed a larger adsorption for pharmaceuticals having low solubility, with Freundlich adsorption parameter, Kf, reaching 46.068 [(mgg-1) (mgl-1)] for Carbamazepine (solubility,
179 mgl-1).
SAC254 (Spectral Absorption Coefficient at 254 nm) can be used as a control parameter for pharmaceutical adsorption studies.
