AbstrakKarya ini sebenarnya adalah sebuah eksperimen, sebuah eksplorasi atas kemungkinan-kemungkinan penerapan motif jumputanbiru pada permukaan keramik. Proses ini bagaimana sebuah penjelajahan tanpa akhir yang hasil-hasilnya menawarkan secaravisual ruang untuk berimajinasi yang selalu penuh dengan kejutan yang dihasilkan dari ikatan, lipatan, kerutan, jelujur, danpewarnaan. Warna dan motif pada kain shibori biru dan pada keramik warna biru cobalt memiliki persamaa yang dekat dalamhal warna. Kesamaan ini dipandang sebagai representasi shibori biru yang diterapkan pada tekstil. Efek visual memunculkanspirit jumputan biru pada keramik yang tidak lagi mengacu pada pemaknaan yang ada pada kain jumputan biru.AbstractThe work I have completed is basically an experiment, an exploration of the possibilities applying blue shibori motif on ceramicsurface. This process is like a never-ending exploration of which the results visually offer space to have imaginations, alwaysfull of surprises resulting from the process of knotting, folding, wrinkling, stitching and coloring. The color and motif on blueshibori cloth and on cobalt blue ceramic have close similarity in color. This similarity is regarded as the representation of blueshibori as applied on textile. The visual effect of this process brings out the spirit of blue shibori on ceramic, which does notrefer to the meaning existing in the blue shibori cloth.

A modular X-ray scanning system was developed, to fill in the gap between portable instruments (with a limited analytical area) and mobile instruments (with large analytical areas, and sometimes bulky and difficult to transport). The scanner has been compared to a commercial tabletop instrument, by analysing a Portuguese tile (azulejo) from the 17th century. Complementary techniques were used to achieve a throughout characterisation of the sample in a complete non-destructive approach. The complexity of the acquired X-ray fluorescence (XRF) spectra, due to inherent sample stratigraphy, has been resolved using Monte Carlo simulations, and Raman spectroscopy, as the most suitable technique to complement the analysis of azulejos colours, yielding satisfactory results. The colouring agents were identified as cobalt blue and a Zn-modified Naples-yellow. The stratigraphy of the area under study was partially modelled with Monte Carlo simulations. The scanners performance has been compared by evaluating the images outputs and the global spectrum.

Microscopic examination and electron microprobe analysis were employed to determine the materials and techniques used to decorate ten glazed types of medieval Islamic ceramics from North Yemen. Eight types were underglaze-painted, one was slip-painted, and one was monochrome glazed. The glazes were of two compositions, soda–silica and lead oxide – silica with annealing temperatures of approximately 835 and 640 °C, respectively. The colourants used in the glazes and paints were cobalt (blue), iron (green), copper (green and blue), and antimony (yellow). Where clay slips or slip-paints were present, alumina enrichment of the glaze had occurred during application or firing, and pigment-paints on top of slip grounds masked enrichment. The Mellor ratio for the lead glazes ranges from 0.68 to 0.74 and is well above the acceptable safety limit of 0.5.

AbstractObjective:Knowledge of injuries of earthquake victims is important to plan relief efforts. This cross-sectional study was conducted following the 08 October 2005 earthquake in Northern Pakistan to determine the pattern of injuries sustained and their relationship with age and gender in order to identify the medical needs in an earthquake-affected zone.Methods:The study was conducted between 13 October and 23 October 2005 at the Emergency Relief Hospital, Doraha, Mansehra. From the 1,700 patients registered in the hospital, 310 were sampled randomly for the study. Demography and details of the patients' injuries were noted by history and physical examination. Twelve cases were omitted due to incomplete data.Results:Of the cases, 54% were female. Children ≤10 years old formed the largest age group. Isolated bone injuries were present in 41%, soft tissue injuries in 36%, and mixed injuries in 23% of the patients.The most common bone injury was lower limb fracture (52%), while the most common non-bone injury was non-infected, soft tissue wounds on the limbs (33%). Among patients with soft tissue injuries, gangrenous wounds were present in 9%, and grossly infected wounds in 30% (20% on limbs and 10% on rest of the body).Conclusions:The population injured during the earthquake showed a higher proportion of females and children ≤10 years old, and lower limb bone injuries. The data highlight the need to address orthopedic, pediatric, and women's health issues, and for logistic arrangement of relevant diagnostic and therapeutic facilities at the initial stages of relief activities after earthquakes.
