We studied hydraulic traits of young plants of the Mediterranean cedar species Cedrus atlantica (Endl.) G. Manetti ex Carrière (Luberon, France), C. brevifolia (Hook. f.) Henry (Cyprus), C. libani A. Rich (Hadeth El Jebbe, Lebanon) and C. libani (Armut Alani, Turkey). With an optimum water supply, no major differences were observed among species or provenances in either stem hydraulic conductiv...

Timo Heikkinen. Bonding of Composite Resin to Alumina and Zirconia Ceramics with Special Emphasis on Surface Conditioning and Use of Coupling Agents. Department of Biomaterials Science, Institute of Dentistry, University of Turku. Annales Universitatis Turkuensis, Turku, Finland 2011. Dental oxide ceramics have been inspired by their biocompability and mechanical properties which have made dura...

The water scarcity that Iraq suffers from and the low irrigation efficiency in projects, therefore, it was necessary to evaluate performance of system western canal for Ishaqi project Salah al-Din Governorate determine management strategies can be used improve project. field evaluated on two fields different crops methods according agricultural reality study area Western Al-Ishaqi Irrigation Pr...

Experiments were performed in a cylindrical 0.14 m diameter bubble column with a metal perforated plate. Air and aqueous solutions of glycerol with viscosity 1–22 mPa s were the phases. Gas holdup was measured and plotted against the gas flow rate. The critical point where the homogeneous–heterogeneous regime transition begins was determined by the drift-flux plot of the primary data. The homog...

This paper proposes the Marine Predators algorithm (MPA) linked with reservoir simulation model and considering sedimentation, in order to improve rule curves. The release criteria of hedging (HR) standard operating policy (SOP) were investigated this study. results showed that patterns new optimal curves from MPA technique sedimentation using HR practically useful study, as SOP those existing ...

The YSZ-NiO ceramics for solid oxide fuel cells (SOFCs) anode have been investigated. A series of specimens were singly reduced in a hydrogenous atmosphere (Ar-5 vol% H2 mixture) at 600 °C under the pressure of 0.15 MPa or subjected to 'reduction in the mixture-oxidation in air' (redox) cycling at 600 °C. The YSZ-Ni cermets formed in both treatment conditions were then aged in 'water vapor in A...

Six different tetracalcium phosphate (TTCP) products were synthesized by solid state reaction at high temperature by varying the overall calcium to phosphate ratio of the synthesis mixture. The objective was to evaluate the effect of the calcium to phosphate ratio on a TTCP-dicalcium phosphate dihydrate (DCPD) cement. The resulting six TTCP-DCPD cement mixtures were characterized using X-ray di...

European Directives consider mercury a priority hazardous substance due to its adverse effects on human health and the environment. In response to environmental concerns, a microencapsulation process has been developed within the European LIFE program as a long-term storage option for mercury. This process leads to the obtainment of a stable concrete-like sulfur matrix that allows the immobiliz...

OBJECTIVES The bonding effectiveness of five adhesive luting agents to enamel and dentin using different application procedures was determined using a micro-tensile bond strength protocol (microTBS). METHODS Enamel/dentin surfaces of human third molars were flattened using a high-speed diamond bur. Composite resin blocks (Paradigm, 3M ESPE) were luted using either Linkmax (LM; GC), Nexus 2 (N...

Nocturnal water flux has been observed in trees under a variety of environmental conditions and can be a significant contributor to diel canopy water flux. Elevated atmospheric CO(2) (elevated [CO(2)]) can have an important effect on day-time plant water fluxes, but it is not known whether it also affects nocturnal water fluxes. We examined the effects of elevated [CO(2)] on nocturnal water flu...
