Application of Glycerol‐Based Adhesives in the Manufacture of Medium‐Density Particleboards

Journal of Applied Polymer Science, EarlyView.
In this study, glycerol‐ and diacid‐based wood adhesives were synthesized and applied to Pinus elliottii wood residues for the manufacture of medium‐density particleboards (MDP). ABSTRACT In this study, glycerol‐ and diacid‐based adhesives were synthesized and applied in the manufacture of medium‐density particleboards (MDP) using pine wood (Pinus ...

Investigation of the surface properties of gangue minerals in PGM bearing ores [PDF]

, 2005
Bibliography: leaves 90-95.The recovery of Platinum Group Minerals (PGM) and associated sulphides by froth flotation from the Bushveld Igneous Complex is complicated by the presence of naturally floatable gangue minerals such as talc.

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

Journal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Clinical resistance to platinum chemotherapy in ovarian cancer [PDF]

, 2009
Platinum drugs are the most active agents in ovarian cancer. Their cytotoxicty results from DNA crosslinking. High tumour response rates are seen, but 80 % of patients relapse. Major mechanisms of platinum resistance in patients remain to be established.

MICRO-PIXE ANALYSIS OF PLATINUM-GROUP MINERALS FROM PLACER DEPOSITS

, 1992
Micro-PIXE and EPMA analyses of platinum-group minerals from placer deposits are being used in an attempt to determine whether the PGM are derived from ultramafic rocks by weathering, or formed directly in the placer by chemical accretion.

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.
