This work deals with the numerical and experimental investigation of flow in protective filters which combine fibrous pleats absorbent cartridge. The through complete 3D geometry all parts filters, including complex pleats, is numerically modeled using high-quality computational grids. sorbent filling, textile dividers as well material filtration are porous media coefficients quadratic Forchhei...

Cementitious materials will be used during the construction and operation of a geological repository for spent nuclear fuel at Olkiluoto in Finland. Upon contacting water, cement dissolution generate high-pH leachates, which might eventually reach proximity canister deposition hole through an interconnected network fractures crystalline host rock. Highly-alkaline conditions near bentonite buffe...

Abstract In order to study the influence of structural factors launch device on missile tilt projectile dynamics, a dynamic model platform was established based finite element method. The effects shock absorber stiffness, angle between and horizontal plane were studied platform’s ejection response characteristics. research results show that greater rigidity absorber, smaller plane, vibration am...

This paper presents the control of Spark Ignition (SI) Internal Combustion (IC) engine Fuel-to-Air Ratio (FAR) using an adaptive control method of time-delay systems. The objective is to maintain the in-cylinder FAR at a prescribed set point, determined primarily by the state of the Three-Way Catalyst (TWC), so that the pollutants in the exhaust are removed with the highest efficiency. The FAR ...

BACKGROUND Interplay between the components of a lipoplasty system (suction pump, suction tubing, collection canister, and cannula) determines liposuction efficiency. However, in clinical practice, none of the components are more important than the cannula. Cannula design including port design, port placement, and shaft characteristics is the single most influential contributor to flow resistan...

In search for a test measuring positive emotions in pigs for application in on-farm welfare auditing, three small experiments were conducted to examine the sensitivity of a novel object test designed to measure the pigs’ (residual) need/motivation for enrichment. In the experiments the interactions with a novel piece of rope were measured at pen level using a so-called AMI sensor (AMI: animal–m...

We present the development and application of small buoy systems for wave energy harvesting (free-floating or slackly moored), to produce about 1 KW per unit at full scale. These systems are targeted for powering distributed marine surveillance and instrumentation networks, and should be simple in concept, easily deployable, storm resilient, and low maintenance. Our work involved design, experi...

The effect of Bacillus subtilis exposure to the human spaceflight environment on growth, mutagenic frequency, and spectrum of mutations to rifampicin resistance (RifR) was investigated. B. subtilis cells were cultivated in Biological Research in Canister-Petri Dish Fixation Units (BRIC-PDFUs) on two separate missions to the International Space Station (ISS), dubbed BRIC-18 and BRIC-21, with mat...

BUTT LITTERING TRUST There is growing concern about this form of unsightly and dangerous pollution. Google shows 63 500 hits for ‘‘cigarette butt’’ and ‘‘litter’’ and the international tobacco industry has got a nasty lungful of this new ill-wind and may be coming soon with a big environmentally friendly smile to run a publicity campaign near you. In Australia, British American Tobacco has set ...

UNLABELLED This study examined the degree to which measures of spontaneous and movement-evoked pain accounted for shared or unique variance in functional disability associated with whiplash injury. The study also addressed the role of fear of movement as a mediator or moderator of the relation between different indices of pain and functional disability. Measures of spontaneous pain, single-poin...
