A List of the Odonata of the La Rue-pine Hills Ecological Area [PDF]

open access: yes, 2017
A survey of the adult odonate fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted during 1983-1985. Thirty six. species were collected including the damselfly Telebasis byersi Westfall; this damselfly is known to occur ...

Estimating Soybean Radiation Use Efficiency Using a UAV in Iowa

open access: yesAgronomy, 2020
Radiation use efficiency (RUE) is difficult to estimate and unreasonable to perform on a small plot scale using traditional techniques. However, the increased availability of Unmanned Aerial Vehicles (UAVs) provides the ability to collect spatial and ...

Rain- and water-use efficiencies of a shrub ecosystem and its resilience to drought in the Central Asia region during 2000–2014

open access: yesGlobal Ecology and Conservation, 2019
As one of the more dominant and relatively stable ecosystems in arid Central Asia, the shrub ecosystem plays an important role in the maintenance of ecosystem stability; therefore, interpreting the results and increased understanding of rain use ...

An extension which is relatively twofold mixing but not threefold mixing

open access: yes, 2004
We give an example of a dynamical system which is mixing relative to one of its factors, but for which relative mixing of order three does not ...

“Not tonight zebrafish”: the effects of Ruta graveolens on reproduction

open access: yesPharmaceutical Biology, 2018
Context: There is growing interest in the pharmacological evaluation of Rue due to its potential to treat a variety of clinical diseases. The plant seems to present potent endocrine disrupting effects, and its excretion and disposal are not a concern ...

Effect of Decreasing Temperature Reciprocating Upsetting-Extrusion on Microstructure and Mechanical Properties of Mg-Gd-Y-Zr Alloy

open access: yesMetals, 2020
The decreasing temperature reciprocating upsetting-extrusion (RUE) deformation experiment was carried out on Mg-Gd-Y-Zr alloy to study RUE deformation on the influence of microstructure of the alloy. This work showed that with the gradual increase of RUE

Growth rate for the expected value of a generalized random Fibonacci sequence [PDF]

open access: yes, 2008
A random Fibonacci sequence is defined by the relation g_n = | g_{n-1} +/- g_{n-2} |, where the +/- sign is chosen by tossing a balanced coin for each n. We generalize these sequences to the case when the coin is unbalanced (denoting by p the probability

Cercetări arheologice în aşezarea eneolitică de la Mălăieştii de Jos (jud. Prahova), campaniile 2002–2010

open access: yesMateriale și Cercetări Arheologice, 2012
North of the Mălăieştii de Jos village (Prahova county), on the edge of a high terrace (295 m altitude), an Eneolithic settlement was noted. To the north and south the site is naturally bordered by deep gullies and ravines, and to the east by the river ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
