The Method of Optimizing Blasting Parameters for Driving Tunnel Based on the Outcome Analyses

, 2011
To get optimum blasting parameter bringing out the best blasting outcome is very helpful to increase the speed and efficiency in tunnel-building. For this reason, the effect of blasting parameters on blasting outcome is analyzed based on that the rocks ...

Fragment Edges Benefit a Common Predator of Pollinators via Bottom‐Up Effects

Integrative Zoology, EarlyView.
This study investigated the hypotheses regarding the effects of habitat fragmentation on spider biomass and causing bottom‐up or top‐down effects on multi‐trophic relationships. ABSTRACT Defaunation following habitat fragmentation typically threatens predators at higher trophic levels, which further alter prey and plants via top‐down effects.

Chromosome‐Level Genome Assembly of Strauchbufo raddei and Multi‐Omic Insights Into Drought Adaptation

Integrative Zoology, EarlyView.
ABSTRACT Understanding how amphibians adapt to terrestrial and arid environments is important for elucidating vertebrate terrestrialization. In this study, we present the first chromosome‐level, high‐quality genome assembly of Strauchbufo raddei, constructed using PacBio HiFi long‐read sequencing and Hi‐C scaffolding. The assembled genome is 4.47 Gb in

Current Approaches to Support Patients to Withdraw From Image and Performance Enhancing Drugs

Clinical Endocrinology, EarlyView.
ABSTRACT Image and performance‐enhancing drugs (IPEDs) include agents such as androgens, growth hormone, and erythropoietin, which are used to enhance appearance and physical performance. Androgens, also known as anabolic‐androgenic steroids (AAS), are the most used IPEDs worldwide.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Study on the Effects of Joints on Tunnel Blasting

, 2011
In the smooth blasting of the tunnel, many studies indicate that the effects of joints on blasting are over than the nature of the rock itself. By analyzing the effects of joints on the strength of blasting rock, the rock surge impedance and the stress ...
