This paper presents the construcrion, newly developed design technologies and performance characteristics of a compact horizontal scroll-type compressor for room air conditione~:s. The authors were able lo develop a compacl variable speed horizontal scroll-type compressor with a cooling capacity of I. 8 kW, which necessitated the development of new mechanisms, namely, an alCial compliance mecha...

In large volumes produced activated sludges from wastewater treatment plants (WWTPs) with low concentrations of heavy metals can be utilized as agricultural fertilizers and soil conditioners. Increased contents of toxic xenobiotics are limiting factors that affect the utilization of these heterogeneous wastes. The main aim of our paper was to show the utilization of dried activated sludge (DAS)...

Gamasoidosis (acariasis, avian-mite dermatitis or bird-mite dermatitis) is a challenging diagnosis that is becoming more common because of the frequent use of window air conditioners in tropical countries. These devices may serve as shelters for nests of urban birds such as pigeons. Dermatologists should become familiar with this infestation to establish the correct diagnosis and treatment.

Over the past few decades, advanced polymeric materials have gained popularity in development of sustainable agricultural applications. Smart systems extensively contributed to industry by increasing efficiency pesticides, herbicides, and fertilizers facilitating controlled release and, therefore, enabling lower doses be used. Superabsorbent been used as soil conditioners control impact drought...

Replacing R-22 by HFC refrigerants in stationary air conditioners is forcing oil producers to develop a new lubricant which has good miscibility with HFC, lubricity and electric resistivity. Mitsui has selected a carbonate compound for a new lubricant candidate with HFC and developed it forcusing on its thermal stability, which is one of the most important factors to get good lubricity. By supp...

PURPOSE The purpose of this study was to evaluate the efficacy of two different metal conditioners for non-precious metal alloys for the bonding of porcelain to a cobalt-chromium (Co-Cr) alloy. MATERIALS AND METHODS Disk-shaped specimens (2.5×10.0 mm) were cast with Co-Cr alloy and used as adherend materials. The bonding surfaces were polished with a 600-grid silicon carbide paper and airborn...
