Reproductive skew models, which focus on the degree to which reproduction is shared equally (low skew) or monopolized by a single individual (high skew) within groups, have been heralded as providing a general unifying framework for understanding the factors determining social evolution. Here, we test the ability of optimal skew, or "transactional," models, which predict the level of skew neces...

in this study, total phenolics and flavonoids content, antiradical and antimicrobial activity of methanolic extract of two iranian acorn varieties, namely quercus.castaneifolia var castaneifolia and quercus.branti var persica were evaluated. total phenolic and flavonoid content and extraction yield of methanolic extract of castaneifolia variety (mc) were significantly higher than that of the ex...

Cocoa powder is a basic ingredient in the manufacture of chocolate, one most appreciated sweet products world for its sensory and nutritional properties. Furthermore, it displays central nervous system stimulant effect. This study aimed to investigate acorn-derived as an alternative cocoa powder, order obtain chocolate that does not contain stimulants system. Both technological process acorns r...

Components of the proteinaceous cement secreted by barnacles have yet to be studied because of their insolubility. We solubilized and characterized the proteins of secondary cement, which is produced when the barnacle is detached from the substratum, in Megabalanus rosa. The cement was fractionated, according to its solubility in aqueous formic acid, into a soluble fraction, SF1 (2 1%); a fract...

In this work we present a multi-modal machine learning-based system, which call ACORN, to analyze videos of school classrooms for the Positive Climate (PC) and Negative (NC) dimensions CLASS observation protocol that is widely used in educational research. ACORN uses convolutional neural networks spectral audio features, faces teachers students, pixels each image frame, then integrates informat...

The size distribution of saline and bronchodilator (terbutaline) aerosol droplets generated from four widely used jet nebulisers (Acorn, Upmist, Turret, and Inspiron Mini-neb) has been measured with a Malvern 2200 Laser Particle Sizer. The mass median diameter of aerosol droplets generated by each nebuliser was strongly influenced by the driving flow rate of compressed air. By increasing the fl...

This research was aimed to evaluate anti-herpes simplex virus type-1 (anti-HSV-1) activity of crude ethanol extract and 4 corresponding fractions of Quercus brantii acorn in vitro. Crude ethanol extract was prepared and subjected to fractionation with different polarity. Anti-HSV-1 activity was evaluated on baby hamster kidney cell line using MTT assay. The inhibitory effect of the plant materi...

Solid and liquid ba~ts were tested for the delivery the latter may be more useful because consumption can be of drugs to white-tailed deer. The solid bait was comprised measured directly, ingestion by nontarget animals is of a mineral block paired with apple, peanut butter, or acorn minimized, and bait degradation by weathering is reduced. extract. The liquid bait was comprised of water, apple ...
