Regarding the achievement of worldwide agricultural climate neutrality, focus is on a net-zero emission cradle-to-farmgate greenhouse gases (GHGs), while, when appropriate, including biogeophysical impacts practices longwave radiation balance. Increasing soil carbon stocks and afforestation have been suggested as that could be currently (roughly) sufficient to achieve neutrality. It appears in ...
Hubbell’s neutral theory of biodiversity has successfully explained the observed composition of many ecological communities but it relies on strict demographic equivalence among species and provides no room for evolutionary processes like selection, adaptation and speciation. Here we show how to embed the neutral theory within the Darwinian framework. In a fitness landscape with a quadratic max...
Background and Aim: High consumption of carbonated diet soda is the most common etiologic factor for dental erosion. The purpose of this study was to evaluate the microhardness of the enamel surface eroded by cola after treatment with Remin Pro and neutral sodium fluoride. Materials and Methods: This in vitro experimental study was performed on 20 extracted premolars with no corrosion, abras...
The rhizome of Anemarrhena asphodeloides is used as food and traditional Chinese medicine for its hypoglycemic effect. The aim of this study was to investigate the isolation, purification and hypoglycemic activity of Anemaran as the active component. The influence factors (isolation duration, ratio of residuals to water and extracting times) during the isolation process were evaluated. The opti...
Background and Objectives: Nowadays, to avoid the use of synthetic preservatives, which do more harm than good, numerous studies are currently focused on using natural ingredients to enhance food product quality and shelf life. Since no study has been conducted on combining coatings with electrolyzed water containing natural antimicrobial compounds, the present study has innovation and priority...
The presence of a proximal cationic group in zwitterionic aryltrifluoroborates such as o-(Ph(2)MeP)C(6)H(4)(BF(3)) stabilizes these compounds against hydrolysis.
This paper describes the APSEN system, a pre-screening tool for detecting sleep apnea in a home environment. The system was designed and evaluated in two parts; the apnea detection using SpO2 and the posture detection using IR images. The two parts can work together or independently. During the preliminary study, the apnea detection algorithm was evaluated using an online database, and the righ...
Previous work has shown that languages differ in their articulatory setting, the postural configuration that the vocal tract articulators tend to adopt when they are not engaged in any active speech gesture, and that this posture might be specified as part of the phonological knowledge speakers have of the language. This study tests whether the articulatory setting of a language can be acquired...
