background: target-controlled infusion is a new delivery system for intravenous anesthetic agents with which the anesthetist targets a plasma or effect-site drug concentration to achieve a predetermined effect. with this system, the tedious task of calculating the amount of administered drug required to achieve the target concentration is left in charge of a microprocessor which commands the in...

A novel delivery system using micron-scale grape skin powder (GSP) was developed that enhanced loading, stability and bioaccessibility of trans-resveratrol (trans-Res). Vacuum assisted infusion GSP results in a high yield (~1 mg/g) trans-Res improved photostability infused exposed to UV-A light. The release from ~ 45% during gastric digestion the total intestinal phase sequential processes low ...

Here we show how food and beverage manufacturers report more incisive sustainability product fulfilment outcomes for their business enterprises when innovative processing technologies are used. The reported steam infusion technology heats materials within a Vaction Pump device so that is directed into the material much reduced volume, reducing use of time. This study reports such technological ...

Ultimate pressure of a well-designed vacuum system very much depends on pretreatments, processing and procedures [1, 2]. Until now much attention has been paid to minimizing hydrogen outgassing from the vacuum chamber wall materials, however, procedures and processing deserve further scrutiny. For reducing the gas load, high sensitivity helium leak detection techniques with sensitivities better...

This study aims to determine the effect of volume fraction corn husk fiber as reinforcement in epoxy matrix composites on tensile strength and fracture analysis specimens. used a variation 20%, 30%, 40%, 50% by using Vacuum Assisted Resin Infusion (VARI) method. Tensile testing patterns were carried out mechanical properties material. The results showed that addition reinforced resin composite ...

This research work aimed to develop smart multifunctional composites via a process for uniformly dispersing carbon nanotubes (CNT) on an orthogonal three-dimensional (3D) woven glass fabric with minimised filtering effect. These could detect strain under tensile and flexural loading by the piezoresistive response of infused CNT network. Conventional vacuum assisted resin transfer moulding was m...

In this study, the mechanical properties, fatigue life, and endurance limit values were investigated for composite materials containing natural fiber reinforcement (flax, wool), which arranged by 0°/90° Angle orientation a combination of 45°/-45° angle orientation, then wool woven mixed flax unidirectional interfered with jute woven. Binary blends epoxy polyurethane at v various weight percent ...

Bismaleimide (BMI) resins are used in carbon fiber reinforced composites for high-temperature applications. Conventional BMI require high cure and post-cure processing temperatures, which limit fabrication methods contribute to residual stress microcracking. Recently, BMIs with lower temperatures have been developed; however, little data on the properties of low-temperature carbon/BMI available...

An investigation was carried out concerning the hydrothermal aging effect on water intake character of aramid/epoxy composites based dimension effect. The were manufactured by vacuum assisted resin infusion method (VARIM) kept in distilled and sea at 25 °C 70 for 6 weeks a controllable cabin. absorption behavior composite samples cut with different length/width (L/w) ratios assessed according t...

Advances in material processing such as silicon micromachining are opening the way to vacuum microelectronics. Two-dimensional vacuum components can be fabricated using the microsystems processes. We developed such devices using a single metal layer and silicon micromachining by DRIE. The latter technological step has significant impact on the characteristics of the vacuum components. This pape...
