In this study, fluoridated strontium apatite (SAP) nanoparticles with different mole percentages (5%, 10%, 30%, and 50%) synthesized using a hydrothermal method were used as biomaterials. The in vivo biocompatibility of the was investigated by embedding them biomaterials bone defects created rat tibiae. Through hematoxylin-eosin staining method, histopathological analysis performed for new form...

Subtropical mixed forest ecosystems are experiencing dramatic changes in precipitation and different plant functional types growing here expected to respond differently. This study aims unravel the water use patterns of their responses environmental a typical subtropical southern China. Diurnal seasonal sap flux densities evergreen broad-leaved trees (EBL), deciduous (DBL), conifers (CON), as w...

A new simple analytical model for prediction of cooling rate in the solidification process based on the local heat flux density extracted during solidification is introduced. In the modeling procedure, a solidifying control volume is considered in the mushy zone in which a heat balance equation is used to derive the present model. As the local heat flux density is a measurable parameter, the pr...

Low density lipoprotein (LDL) from patients with coronary heart disease (CHD) caused 78-286% increase in accumulation of cholesterol in human aortic subendothelial cells compared to 2-17% caused by LDL from normal subjects. Ricin-Sepharose affinity chromatography was used to separate LDL into two subfractions, one sialic acid-rich (SAR) and the other sialic acid-poor (SAP). SAP-LDL from CHD pat...

Nocturnal fluxes may be a significant factor in the annual water budget of forested ecosystems. Here, we assessed sap flow in two co-occurring evergreen species (Eucalyptus parramattensis and Angophora bakeri) in a temperate woodland for 2 years in order to quantify the magnitude of seasonal nocturnal sap flow (E(n)) under different environmental conditions. The two species showed different diu...

We investigated the effect of drought on canopy stomatal conductance (g(c)), and examined the hypothesis that g(c) is controlled by the chemical messenger abscisic acid (ABA) produced in roots. Beginning in November 1994, we subjected a mature stand of Scots pine (Pinus sylvestris L.) to an imposed 11-month drought. Control plots were maintained at average-season soil water content. Xylem sap w...
