Horton laws for hydraulic–geometric variables and their scaling exponents in self-similar Tokunaga river networks [PDF]

open access: yesNonlinear Processes in Geophysics, 2014
An analytical theory is developed that obtains Horton laws for six hydraulic–geometric (H–G) variables (stream discharge Q, width W, depth D, velocity U, slope S, and friction n') in self-similar Tokunaga networks in the limit of a large network order ...

Sources of Discomfort in Persons with Dementia: Scale and Initial Results

open access: yesBehavioural Neurology, 2015
The Sources of Discomfort Scale (SODS) assesses discomfort manifestations based on source of discomfort, thus making it both distinct from and complementary to pain assessments for persons with dementia.

The River Systems in Small Catchments in the Context of the Horton’s and Schumm’s Laws – Implication for Hydrological Modelling. The Case Study of the Polish Carpathians

open access: yesQuaestiones Geographicae, 2015
In ungauged catchments, flood hydrographs are usually simulated/reconstructed by simple rainfall-runoff and routing models. Horton’s and Schumm’s ratios serve as the input data for many of these models. In this paper, more than 800 Carpathian catchments (

Hierarchical ordering of reticular networks. [PDF]

open access: yesPLoS ONE, 2012
The structure of hierarchical networks in biological and physical systems has long been characterized using the Horton-Strahler ordering scheme. The scheme assigns an integer order to each edge in the network based on the topology of branching such that ...

AGU Hydrology Awards: Horton, Horton, and Horton

open access: yesEos, Transactions American Geophysical Union, 1984
There are three individual awards available to hydrologic researchers through the AGU. All three bear the name of Robert E. Horton, and because of this there appears to be considerable confusion among the membership as to the purpose of the awards, eligibility for them, and the method of their adjudication.The Horton Medal is a Union award. It is given

Strengthening Treaty Understanding: The Role of Education in Building Durable Indigenous–State Agreements

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Education is a central mechanism for ensuring that Indigenous–State treaties are understood, supported and endure through political change. Public knowledge shapes the negotiation, acceptance, implementation and long‐term stability of agreements. In Australia, however, treaty knowledge remains fragmented.

A pilot study demonstrating a non‐invasive method for the measurement of protein turnover in skin disorders: application to psoriasis

open access: yesClinical and Translational Medicine, 2013
Background Previous studies of epidermal kinetics in psoriasis have relied on invasive biopsy procedures or the use of radioactive labels. We previously developed a non‐invasive method for measuring keratin synthesis in human skin using deuterated water ...

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

Building families—Implementing balanced sexual and reproductive health

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract One of the main initiatives of the World Health Organization (WHO) is the promotion of Sexual and Reproductive Health (SRH). Sexuality, infertility, and contraception are three interconnected pillars of SRH, each essential for achieving global equity in family planning and family building.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...
