Behaviorally mediated trophic cascades (BMTCs) occur when the fear of predation among herbivores enhances plant productivity. Based primarily on systems involving small-bodied predators, BMTCs have been proposed as both strong and ubiquitous in natural ecosystems. Recently, however, synthetic work has suggested that the existence of BMTCs may be mediated by predator hunting mode, whereby passiv...

Abstract The aim of this case study is to develop a process model including both heat integration and separation processes by means of ASPEN PLUS simulation software. Previous studies have attempted to develop kinetic models or to retrieve optimal policies for operating the process multitubular catalytic fixed-bed reactor. This time a rigorous model is developed in ASPEN CUSTOM MODELER and expo...

purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...

Three-dimensional computational fluid dynamics (CFD) modeling of the gasification performance in a one-stage, entrained-bed coal gasifier (Shell Coal Gasification Process (SCGP) gasifier) was performed, for the first time. The parametric study used various O2/coal and steam/coal ratios, and the modeling used a commercial code, ANSYS FLUENT. CFD modeling was conducted by solving the steady-state...

This paper describes the ASPEN system for automation of planning and scheduling for space mission operations. ASPEN contains a number of innovations including: an expressive but easy to use modeling language, multiple search (inference) engines, iterative repair suited for mixed-initiative human in loop operations, real-time replanning and response (in the CASPER system), and plan optimization....

The petrochemical industry is traditionally a high energy consumption industry, thus saving in this of great significance terms trying to achieve the national goal “carbon-peak and carbon neutrality” China. Diesel one main products enterprises. diesel hydrotreating (HDT) unit relatively due reaction temperature pressure HDT reactors. In order further explore units under different operating cond...

Vegetative regeneration of aspen can be initiated through manipulations that provide hormonal stimulation, proper growth environment, and sucker protection—the three elements of the aspen regeneration triangle. The correct course of action depends upon a careful evaluation of the size, vigor, age, and successional status of the existing clone. Soils and site productivity, competition from other...

At low-energy radioactive ion beam facilities such as SHIPTRAP and the Low-Energy Branch of the Super-FRS at FAIR, mass measurements and spectroscopy for a broad range of nuclei can be performed. Access to these nuclei is limited by their lifetime and the amount of isobaric contamination. To help to overcome these limitations, a multiplereflection time-of-flight mass spectrometer (MR-TOF-MS) sy...
