Permeability of Sand-bentonite and Sand-fly Ash Mixtures
Laboratory hydraulic conductivity (HC) tests have been conducted on mixtures of fine sand with bentonite and fly ash with four fluids with different pH and metal concentrations with a view to assess their suitability for liner constructions for waste containment facilities.

Leishmaniasis transmission biology: Role of Promastigote Secretory Gel as a transmission determinant [PDF]
Leishmaniasis is a complex vector-borne disease caused by Leishmania sp. (Kinetoplastida: Trypanosomatidae) and is transmitted by female sand flies (Diptera: Psychodidae).

Breeding switchgrass for reduced nitrogen demand
Breeding has improved switchgrass biomass yield, but productivity is still heavily dependent on nitrogen fertilizer application. The genetic diversity needed to improve nitrogen use efficiency of switchgrass remains underused, mainly because of the slow and laborious breeding process, thus leaving the crop's high nitrogen demand as a major barrier to ...

Leishmania sand fly interaction: progress and challenges [PDF]
Complex interactions occurs between Leishmania parasites and their sand fly vectors. Promastigotes of Leishmania live exclusively within the gut, possess flagella and are motile, and kinesins, kinases and G proteins have been described that play a role in regulating flagellar assembly.

ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

We used GPS video camera collar data from barren‐ground caribou in the Porcupine and Western Arctic herds to validate antler‐ and movement‐based methods for estimating annual reproductive metrics. Antler retention was highly accurate for estimating parturition, but the movement methods we tested performed marginally for estimating parturition and ...

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is
