The remarkable increase in chondrocyte volume is a major determinant in the longitudinal growth of mammalian bones. To permit a detailed morphological study of hypertrophic chondrocytes using standard histological techniques, the preservation of normal chondrocyte morphology is essential. We noticed that during fixation of growth plates with conventional fixative solutions, there was a marked m...

Abstract This study has quantified basic wood density and various types of shrinkage in relation to initial spacing (or planting density) tree growth based on a 48-year-old black spruce ( Picea mariana ) trial eastern Canada. A total 139 sample trees were collected from four spacings (3086, 2500, 2066, 1372 trees/ha) for this study. Analyses variance (ANOVA) show that is the most important para...

A brief review of the modern QCD theory of diffractive DIS is given. The recent progress has been remarkably rapid, all the principal predictions from the color dipole approach to diffraction-the (Q 2 +m 2 V) scaling, the pattern of SCHNC, shrinkage of the diffraction cone in hard diffractive DIS, the strong impact of longitudinal gluons in inclusive J/Ψ production at Tevatron-, have been confi...

Conventional breeding requires long breeding cycles which limits selection intensity due to large tree sizes and high costs associated with assessing properties. In contrast very early selection offers a short cycle and assesses corewood which is the poorest wood in the tree. Young Pinus radiata trees were deliberately leant to produce separately opposite wood (OW) and compression wood (CW). Th...

Longitudinal item response data are common in social science, educational and psychology, among other disciplines. Studying the time-varying relationships between items is crucial for assessment or designing marketing strategies from survey questions. Although dynamic network models have been widely developed, we cannot apply them directly to because there multiple systems of nodes with various...

Five native pyrokinin-like peptides (Neb-PK-1, Neb-PK-2, Neb-PVK-1, [L9]Neb-PVK-2, [I9]Neb-PVK-2) identified in the neuropeptidome of the flesh fly Neobellieria bullata were compared for their quantitative and/or qualitative effects on puparium formation (pupariation). In a standard pupariation bioassay, both Neb-PVK-1 and [I9]Neb-PVK-2 proved inactive, whereas [L9]Neb-PVK-2 demonstrated only w...

The early age shrinkage is responsible for the early age cracking of concrete. It is very critical for durability of concrete. The change in volume of concrete due to evaporation of water or dehydration process is known as shrinkage. To reduce the early age shrinkage utilized the supplementary cementitious material (SCM) in concrete. In present research industrial and agricultural waste byprodu...

The objective of this study was to investigate quality changes of salmon fillet muscle during thermal sterilization processes. Small samples (D 30 mm x H 6 mm) from the central dorsal region were heated in an oil bath at 121.1 degrees C for periods varying from 5 to 120 min. The quality variations along the longitudinal axis of salmon fillets (raw and heated) were examined. The quality properti...

because thin plate reinforced concrete members such as walls and slabs are greatly influenced by the drying shrinkage, cracks can occur in these members due to the restraint of the volume change caused by drying shrinkage. therefore, the control of cracking due to drying shrinkage is very important in building construction that the thin plate members are frequently used. however, few researches...
