The aim of this study was to evaluate the biodiversity ofplant associations in On Ebn-e-Ali Mountain in Tabriz and its relationship to various biodiversity indices. Four plant associations including 1) Noaea mucronata- Poetum bulbosa, 2) Noaea mucronata- Brometum tomentellus, 3) related to bush form as well as Poeto bulbosa-Brometum tomentellus and4) Brometo ...

The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an exotic woodborer first detected in 2002 in Michigan and Ontario and is threatening the ash resource in North America. We examined the effects of light exposure and girdling on green ash (Fraxinus pennsylvanica Marsh) volatile production, and effects of light exposure, girdling, and leaf age on emerald ash bore...

euphorbia is a genus of flowering plants belonging to the family euphorbiaceae. consisting of 2008 species. the genus euphorbia produces an irritant, which constitute a health hazard to humans and livestock. the genus euphorbia is one of the largest and most complex genera of flowering plants, however, several botanists have made unsuccessful attempts to subdivide it to smaller genera.  many eu...

Liner design is becoming an increasingly more important tool for the AG/SAG mill performance optimization. The Gol-E-Gohar iron ore concentration plant uses three 9 m × 2.05 m autogenous mills (AG) in parallel in a dry operation. Due to large variations in feed characteristics and inadequate blending, the performance of AG mills has been lower than the target value. In order to increase the cir...

In this paper, we develop an economically optimizing Nonlinear Model Predictive Controller (E-NMPC) for a complete spray drying plant with multiple stages. In the E-NMPC the initial state is estimated by an extended Kalman Filter (EKF) with noise covariances estimated by an autocovariance least squares method (ALS). We present a model for the spray drying plant and use this model for simulation...

In order to screen a suitable resin for the preparative simultaneous separation and purification of syringin, eleutheroside E and isofraxidin from Acanthopanax senticosus, the adsorption and desorption properties of 17 widely used commercial macroporous resins were evaluated. According to our results, HPD100C, which adsorbs by the molecular tiers model, was the best macroporous resin, offering ...

Among apolipoproteins, apolipoprotein E (Apo E) plays a pivotal role in lipid transport and is proposed to be involved in neural repair. Because of a long divergence history of apolipoproteins, it is unclear how Apo E evolved in time. To investigate relationships among Apo E proteins, we used the information from molecular data and analysed the phylogeny of Apo E proteins from various species. ...

A new anthraquinone derivative, named anthrasesamone F, was isolated from the seeds of Sesamum indicum. Its structure was determined to be (Z)-6,7-dihydroxy-2-(6-hydroxy-4-methyl-3-pentenyl)anthraquinone on the basis of spectroscopic evidence.

In the arid Mojave Desert, the phenological response of vegetation is largely dependent upon the timing and amount of rainfall, and maps of annual plant cover at any one point in time can vary widely. Our study developed relative annual plant growth models as proxies for annual plant cover using metrics that captured phenological variability in Moderate-Resolution Imaging Spectroradiometer (MOD...
