Titanium and titanium alloys are often used in orthopedic surgery and dentistry because of their especial characteristics such as biocompatibility, mechanical properties, and corrosion resistance. However, their bio- inertness is the most serious drawback for biomedical applications. Therefore, a bioactive coating like hydroxyapatite (HA) is coated on their surface. In this regard, in the prese...
Type of growing medium affects growth of the hydroponic crops. In order to select a suitable medium for hydroponic lemon balm, two greenhouse experiments were carried out on growing media containing different particle sizes of perlite and peat moss mixed with perlite. In the first experiment, growing media treatments were very fine perlite (<0.5 mm), fine perlite (0.5-1 mm), medium perlite (1-1...
Currently, the idea of integrating nature and buildings through green roofs and green walls has been considered as a sustainable strategy in cities. However, studies on the substrates which allow the plants to fully establish in these systems are still lacking. It is also a challenge to find the substrates which provide the plants with proper growth, nutrition, and environmental sustainabilit...
abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...
Because humans and animals encounter various situations, the ability to adaptively decide upon responses to any situation is essential. To date, however, decision processes and the underlying neural substrates have been investigated under specific conditions; thus, little is known about how various conditions influence one another in these processes. In this study, we designed a binary choice t...
Protein kinases are major signaling molecules that are involved in a variety of cellular processes. However, the molecular mechanisms whereby protein kinases discriminate specific substrates are still largely unknown. Ca(2+)-dependent protein kinases (CDPKs) play central roles in Ca(2+) signaling in plants. Previously, we found that a tobacco (Nicotiana tabacum) CDPK1 negatively regulated the t...
