Economic Analysis of a Water Truck for Feedyard Dust Suppression [PDF]

Dust created in feedyards can adversely affect cattle performance. Dust suppression can be accomplished by moistening pen surfaces with traveling gun(s) sprinklers, solid-set sprinklers, and water trucks.

Cerebrospinal Fluid Cytokine Expression and Relationships With Neurological Measures in Virologically Controlled People With HIV

Annals of Neurology, EarlyView.
Objective Quantify cytokines in cerebrospinal fluid (CSF) of virologically suppressed people with HIV (PWH) and people without HIV (PWoH) and correlate these with neuroimaging, neuropsychometric (NP), and neurodegenerative measurements. Methods CSF samples were collected from virologically suppressed PWH and demographically matched PWoH under a natural

The Origin of Dust in the Early Universe [PDF]

, 2011
In this talk I will describe the origin of dust in the early universe. I will be presenting observations of the spectral energy distribution of the galaxy J1148+5251, and present estimates of the dust mass in this high redshift (z=6.4) object.

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

First evidence of a mandibular crest in Brasileodactylus Kellner, 1984 (Pterosauria, Pteranodontoidea, Anhangueridae), with comments on pterosaur headcrests

The Anatomical Record, EarlyView.
Abstract Brasileodactylus araripensis Kellner, 1984, is a toothed pterosaur from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. Traditionally regarded as crestless, the species has been central to debates on anhanguerid taxonomy, as most members of the clade possess well‐developed sagittal cranial or dentary crests.

Confined Circumstellar Material as a Dust Formation Site in Type II Supernovae

The Astrophysical Journal
We propose a model for dust formation in Type II supernovae (SNe) interacting with confined circumstellar material (CSM), motivated by recent time-domain surveys that have revealed a substantial fraction of SN progenitors to be surrounded by CSM ejected ...

Sport, Agency and Pigeon Snaring in the Ancient Tongan Chiefdom

Archaeology in Oceania, EarlyView.
ABSTRACT Pigeon snaring was an élite sport in the traditional Tongan chiefdom, undertaken on purpose‐built mounds known as sia heu lupe. LiDAR imagery combined with field survey and mound documentation on the island of Tongatapu has identified a comprehensive corpus of these sites.

A Study on Dust Dry Deposition: Wind-tunnel Experiment and Improved Parameterization [PDF]

, 2013
Dust deposition is a key component of the dust cycle in the Earth system. The lack of understanding for the mechanisms of dust deposition has been a major bottle neck to the development of the dust-related research field.
