in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

cazro3 nanoceramics were successfully synthesized at 700 c using the molten salt method, and the effects of processing parameters, such as temperature, holding time, and amount of salt on the crystallization of cazro3 were investigated. cacl2, na2co3, and nano-zro2 were used as starting materials. on heating, cacl2–nacl molten eutectic salt provided a liquid medium for the reaction of caco3 an...

BACKGROUND The purpose of our investigation was to compare a digital templating system to conventional templating techniques when preoperatively planning for total hip arthroplasty. METHODS We included 18 consecutive patients with primary osteoarthritis undergoing uncemented total hip arthroplasty in our study. At separate sittings, we independently conducted preoperative templating. They per...

Reconfigurable cores support post-release updates which shortens time-to-market while extending circuits’ lifespan. Reconfigurable cores can be provided as hard cores (ASIC) or soft cores (RTL). Soft reconfigurable cores outperform hard reconfigurable cores by preserving the ASIC synthesis flow, at the cost of lowering scalability but also exacerbating timing closure issues. This article tackle...

BACKGROUND The Kato-Katz technique is recommended for the diagnosis of helminth infections in epidemiological surveys, drug efficacy studies and monitoring of control interventions. We assessed the comparability of the average amount of faeces generated by three Kato-Katz templates included in test kits from two different providers. METHODS Nine hundred Kato-Katz thick smear preparations were...

Zinc citrate was prepared and its thermal decomposition investigated by methods of thermogravimetric analysis differential scanning calorimetry. Products the were X-ray diffraction analysis. The proceeds at temperatures 50 - 420 °C in three stages leads to formation nanocrystalline ZnO with average grain size 23 nm. Subsequently, zinc used as a precursor hard template for preparation carbon mes...

In tissue engineering, biomaterials play a critical role, act as a 3D template, provide mechanical support, and give artificial extracellular matrix environment (ECM) for neo-tissue formation. Only one type of biomaterials is not enough for both hard and soft tissue engineering. That’s why all types of biomaterials i.e. metals, ceramics, & polymers have their own importance in making tissue eng...

computer aided pulmonary nodule detection has been among major research topics lately to help for early treatment of lung cancer which is the most lethal kind of cancer worldwide.some evidence suggests that periodic screening tests with the ct of patients will help in reducing the mortality rate caused by the lung cancer. acomplete and accurate computer aided diagnosis (cad) system for detectio...

gold nanoparticles were synthesized by chemical reduction of haucl4 inside the pores of a polycarbonate-based membrane followed by dissolving the membrane in dichloromethane and further sonication. sonication time as the main affecting factor on the nanoparticle size was investigated. the characterization by transmission electron microscopy showed the formation of gold nanoparticles with diamet...

We study the binary corrected X-ray light curve of Cygnus X-3 using the RXTE-ASM (All Sky Monitor) data and RXTE-PCA data. We find that the X-ray template derived from the EXOSAT observations adequately explains the binary variations. Using the recently determined quadratic binary ephemeris we correct the RXTE-PCA lightcurve and obtain the power spectrum which shows distinct features of shiftin...
