Air conditioner is an equipment which present in most buildings around the world, either serving to provide greater thermal comfort its users, or as part of industrial processes. This while operation produces water from condensation air contact with coil, has potential be used for non-potable purposes within buildings. study aims evaluate quality condensate conditioners purposes. Water collecti...

In this study, potassium vapor was prepared by using carbonate (K2CO3) and activated carbon (C) reagents to simulate the actual situation of adsorbing from sinter in blast furnace. The potassium-rich characterized X-ray diffraction (XRD), flame atomic absorption spectrometry (FAAS), scanning electron microscopy (SEM-EDS). effects content on enrichment ratio, adsorption rate, low-temperature red...

Copper foam has been prepared using the powder metallurgy process and carbonate dissolution in water. The potassium ratio that added to mixture were (30, 40, 50) wt % respectively. Compacted samples fabricated at pressure of 200 Mpa. was undertaken warm sintering 875 oC for 3 hours an argon (Ar) atmosphere. results show copper foams with porosity 71.8 83 successfully, have a pore size (0.130, 0...

PURPOSE To compare the Jay Sensitivity Sensor Probe (Jay Probe), a new microprocessor-based, pre-calibrated instrument, with well accepted methods used to evaluate sensitivity, i.e. tactile response to the Yeaple Probe, air blast (Schiff scale), and patient responses by Visual Analog Score (VAS). METHODS Jay Probe assessments were accomplished using several approaches. With a cohort of 12 sub...

Tissue sections are prepared and coated with NTB 3 Eastman Kodak emulsion for radioautography in the usual way. After they have been exposed for a suitable time they are processed with no agitation in the following solutions, which must be freshly prepared. Place for 3 min at 24° C in a developer solution which contains per litre 40 g sodium carbonate, 2 g sodium sulphite, 1 g potassium bromide...

Consumption of acidic foods and drinks and other factors that cause enamel wear are responsible for the daily enamel loss and degradation. Use of some toothpastes that have been showed to possess different properties of remineralisation and/or repair of the enamel surface may help to protect tooth enamel. The aim of this study was to evaluate whether the use of toothpaste containing Zn-carbonat...

Surface facilities including tubing and valves at the oilfield have been plagued by mineral scale deposits, which are constitute of calcium carbonate (CaCO3). Penta-potassium diethylenetriaminepentaacetic acid salt (DTPA-K5) has a higher affinity for metal cations complexes during chelation process. The eight complexing sites (five carboxylate three amines) empower ion interactions. This work i...

Beaches are good indicators for local microplastic distribution and pollution. Multiple methods have been developed extracting microplastics from sediment through density separation. However, the chemicals applied often expensive harmful to user or environment. We briefly review problems associated with use of these present a new floatation medium, potassium carbonate (K 2 CO 3 ), that has many...
