Carbon storages and sequestration potentials in remnant forests of different patch sizes in northern Ethiopia: an implication for climate change mitigation

Agriculture & Food Security, 2022
Background Forests provide various ecosystem services. They are natural capitals that enhance nature to regulate itself via carbon sinks. However, anthropogenic and natural factors have altered their CO2 sequestration and carbon storage potentials.

Surface, thermal and hemocompatible properties of novel single stage electrospun nanocomposites comprising polyurethane blended with bio oilTM

Anais da Academia Brasileira de Ciências, 2017
In this work, the physicochemical and blood compatibility properties of prepared PU/Bio oil nanocomposites were investigated. Scanning electron microscope (SEM) studies revealed the reduction of mean fiber diameter (709 ± 211 nm) compared to the pristine

Exploring Context with Deep Structured models for Semantic Segmentation

, 2017
State-of-the-art semantic image segmentation methods are mostly based on training deep convolutional neural networks (CNNs). In this work, we proffer to improve semantic segmentation with the use of contextual information.

Does the waggle dance help honey bees to forage at greater distances than expected for their body size? [PDF]

, 2015
A honey bee colony has been likened to an oil company. Some members of the company or colony prospect for valuable liquid resources. When these are discovered other group members can be recruited to exploit the resource. The recruitment of nestmates to a

Analysis of hypersensitivity in fragrance series by patch testing

Indian Dermatology Online Journal, 2019
Allergic contact dermatitis (ACD) is an inflammatory disorder, which occurs as a result of repeated contact with an allergen. Fragrances are the products obtained naturally or produced synthetically. The purpose of this study is to detect the fragrance allergens producing ACD.This is an open-label prospective observational study.
