Boosting of the enhanced permeability and retention effect with nanocapsules improves the therapeutic effects of cetuximab

open access: yesCancer Biology & Medicine, 2020
Objective: The introduction of therapeutic antibodies (tAbs) into clinical practice has revolutionized tumor treatment strategies, but their tumor therapy efficiency is still far below expectations because of the rapid degradation and limited tumor ...

Method for machining holes in composite materials [PDF]

open access: yes, 1987
A method for boring well defined holes in a composite material such as graphite/epoxy is discussed. A slurry of silicon carbide powder and water is projected onto a work area of the composite material in which a hole is to be bored with a conventional ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

The bi-composite transition joint [PDF]

open access: yes, 1972
The application of advanced composite materials to high performance structure frequently results in the desire to fabricate a structure from more than one composite system in order to tailor the composite material capabilities to the design requirements.

Scattering loss in electro-optic particulate composite materials [PDF]

open access: yes, 2007
The effective permittivity dyadic of a composite material containing particulate constituent materials with one constituent having the ability to display the Pockels effect is computed, using an extended version of the strong-permittivity-fluctuation ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Synthesis and Antibacterial Activities of Sulfur-Containing Bissalicylaldehyde Schiff Base and Binuclear Nickel(II) Nanorod Complex

open access: yesJournal of Chemistry, 2013
Nickel(II) acetate tetrahydrate was treated with the ligand CH2(H2sal-sbdt)2 in methanol heated at reflux to yield a novel binuclear Ni(II) nanorod complex of the formula CH2{Ni(II)(sal-sbdt)(H2O)}2.

Computational analysis of projectile impact resistance on aluminium (a356) curvilinear surface reinforced with carbon nanotubes (cnts) for applications in systems of protection [PDF]

open access: yes, 2017
Computational tests for ballistic impact energy absorption were developed on A356/CNTs composite material with the goal of estimating the improvement of the material’s mechanical properties by the contribution of the CNTs [1].

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using
