Abstract Gram staining is a laboratory technique used to differentiate gram negative and gram positive bacterial cells using light microscopy. The procedure was invented in 1884 by a bacteriologist, Christian Gram. Gram negative bacterial cells have a thin peptidoglycan wall within the cell membrane. During gram staining, these cells decolorize and the peptidoglycan wall maintains … Read more
The paper analyzes a solar photovoltaic power plant serving an office building located in southern Italy. Space heating and cooling building demand is satisfied by a ground source heat pump partly activated by electric energy available from photovoltaic panels. Thermo-economic performance of this system varying photovoltaic peak power (4.5-7.5 kW) and electric battery capacity (3.2-9.6 … Read more
Feeding the ever-growing world population with limited environmental resources is a topic of growing concern. Specifically, consumer demand for animal-based protein sources such as meat and milk have risen due to increased wealth of some populations (Follett and Hatfield, 2001; Helms, 2004; Robinson, 2010).

Metals recycling from WEEE helps substantial level of energy saving then metal minimizing from ores. For instance, Cui and Forssberg (2003), advised that the extaction and recovering of metals (Al:95%, Cu:85%, Fe:74%, Pb:65%, and Zn:60%) saves level of the overall energy needed to mine them from primary resources. Thus, recovery of metals from WEEE has … Read more
