objectives: the aim of this research was to study information seeking behavior and the pattern of reading behavior of faculty members of university of social welfare & rehabilitation sciences in using printed and electronic resources. methods: the descriptive research method was a survey method. the research was implemented by using an organized questionnaire which was distributed among the sta...

In general, visual clusters are preferred over large data sets; this is an attempt to take advantage of cluster techniques reduce the mathematical complexity small sets. To identify possibility implementing clustering technique in a dataset, wear observations PLA/Cu composite samples printed using Fused Deposition Model (FDM) taken into consideration. study, Self Organizing Map (SOM) tool as no...

This research is focused on structural and electrical characterisation of tin oxide (SnO2) applied as a thick film and investigation of its properties as gas sensitive material. Micron sized SnO2 powder was milled in an agate mill for six hours to fabricate SnO2 nanopowder, which was afterwards sieved by 325 mesh sieve and characterized by XRD and SEM. This powder was used as functional part in...

In the present study, inkjet-printing (IJP) technique is used for development of a planar microwave sensor aimed at dielectric characterization biological samples. The proposed consists two capacitively coupled split-ring resonators (SRRs) fabricated using microstrip technology. A silver-based conductive ink deposited by IJP on conventional 1.6-mm-thick FR4 substrate, thus creating resonant str...

The analysis of mechanical response and deformation-cracking behavior contributes to the high-efficiency extraction geo-energy long-term safety underground engineering structures. Compared natural cores, properties 3D-printed samples made from quartz sand as raw material are relatively homogeneous, can be used for quantitative studies on influence defects rocks. In this work, with single fractu...

This study investigates the addition of Poly-vinyl Alcohol (PVA) fibres and attapulgite nanoclay to alkali-activated materials (AAMs) with aim enhancing mechanical performance optimizing printability buildability AAMs. The fresh properties six mix formulations, including flowability, slump values, rheology, shape retention, extrusion window, were evaluated. best performing mixes, that exhibited...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

The purpose of this study was to investigate the effect of type of alcohols and humectants in inks formulation, and the papers surface morphology on the ink-jet printing properties. In order to investigate the influence of alcohol and humectant types on printing properties, the optimum ink formulation from previous study, which contained C.I. Reactive Blue 21 Ink2 was formulated with different ...
