This research aimed to determine the physical properties and advantages of cement boards made from sago stem bark waste based on the test results of several parameters according to JIS A 5908 (2003) standard. The results showed that the physical properties of cement board from sago stem bark waste with the addition of the CaCl2 catalyst were good, with the average value of density ranged from 1.19-1.26 gr/cm³, water content 7,67-8,02%, and water absorption after immersion 2 hours 6,03-7.65% as well as after 24-hour immersion 11,62-12,91%, respectively. The averages swelling value of board thickness was 1.62-12,91% after immersion 2 hours and 1.40-3.41% after immersion 24 hours. Furthermore, what sago bark waste in various positions of the tree trunk (tree base, middle and top) can be utilized to manufacture cement board. The board made from sago stem bark waste at the base position with a catalyst CaCl2 6% has the best physical properties and meets JIS A 5908 (2003) standard. Cement board from sago stem bark waste has an excellent waterproof capability and can be used as outdoor materials.

Furthermore, sago bark waste in various positions of the tree trunk (tree base, middle, and top) can be utilized to manufacture the cement board. However, the board made from sago stem bark waste at the ground with the addition of a catalyst CaCl2 6% has the best physical properties and meets JIS A 5908 (2003) standard. Cement boards from sago stem bark waste have an excellent waterproof capability and can be used as outdoor materials.

Flexography is an evolving printing technology that is suitable for printing on coated and uncoated paperboard and board, nonporous substrates including metalized and paperboard foils, and plastic films used especially in the packaging industry. This study evaluated the effect of paperboard and ink characteristics on flexographic print density in paperboard. Three commercial paperboards from different companies were prepared: brown kraft from Thailand, white kraft from Spain, and test liner from Iran. Four samples of process print inks from Iran were used in this investigation. Paperboard properties, such as roughness and water absorption, and ink characteristics, including solids content, PH and particle diameter, were measured. The inks were printed on paperboards using a roll no.15 applicator with a blade metering device, and the print densities were measured. Results showed that solids content, pH, and particle diameter of printing inks influenced print density, while the roughness and water absorption of the three types of paperboard had no significant influence on print density. Results also illustrated that two levels of ink viscosity (25–30 and 50–55 mPa·s) were insignificant to print density.

The present investigation deals with the formulation of fast disintegrating tablets of Meloxicam that disintegrate in the oral cavity upon contact with saliva and there by improve therapeutic efficacy. Meloxicam is a newer selective COX-1 inhibitor. The tablets were prepared by wet granulation procedure. The influence of superdisintegrants, crosspovidone, croscaremellose sodium on disintegration time, wetting time and water absorption ratio were studied. Tablets were evaluated for weight and thickness variation, disintegration time, drug content, in vitro dissolution, wetting time and water absorption ratio. The in vitro disintegration time of the best fast disintegrating tablets was found to be 18 sec. Tablets containing crospovidone exhibit quick disintegration time than tablets containing croscaremellose sodium. The fast disintegrating tablets of Meloxicam with shorter disintegration time, acceptable taste and sufficient hardness could be prepared using crospovidone and other excipients at optimum concentration.
