Fermentation is an environmentally friendly method to improve feed quality. Fermented liquid feed and airtight stored moist crimped cereal grain systems that are of increasing importance in agricultural practice were studied. Both rely on spontaneous microbial developments with poorly understood population dynamics, resulting in unpredictable final quality. Temperature, fermentation time and in...

The present study provides a correlation and regression analysis of lightweight waste aggregate concretes with varying degrees fibre reinforcement. concrete mix contains pre-soaked red ceramic aggregate, expanded clay coarse Portland cement. Copper-coated crimped steel was used as the experimental results included properties measured by destructive test methods—compressive strength, splitting t...

A completely randomised design study involving 132 continental crossbred beef steers was undertaken to evaluate the effects of method of grain treatment and feed level, and grass silage feed value on animal performance, carcass characteristics and meat quality of beef cattle. Winter wheat was harvested and the grain was stored either ensiled crimped and treated with 4.5 l/t of a proprietary aci...

Three-point bending tests on notched beams of three types of steel fiber-reinforced self-compacting concrete (SFRSCC) have been performed by using both a servo-hydraulic machine and a drop-weight impact instrument. The lo ading rates had a range of six orders of magnitude from 2.20 × 10-3 mm/s (quasi-static) to 2.66 × 10³ mm/s. These SFRSCCs had the same matrix, but various types of steel fiber...

Using electromechanical technique, various conductive carbon fibers and graphite and steel filaments/epoxy micro-composites were evaluated by measuring electrical resistivity to investigate the interfacial properties including the microfailure modes and interfiber distance effect with a aid of acoustic emission (AE). Micromechanical techniques, such as pull-out and fragmentation tests, and elec...

Steel Fiber-Reinforcement is a way to strengthen concrete structures which results to be more flexible and less expensive than the conventional hand-tied rebars, while still increasing the tensile strength. In order to ensure the prescribed tensile strength, the conglomerate needs to have a certain volumetric density of fibers uniformily distributed over the structure. In this paper, a novel st...

in this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. in the created model, both pile and surrounding soil are modeled using fiber elements in a practical beam on nonlinear winkler foundation (bnwf) concept. herein, the features of drain–3dx finite element software are ...

Background: This paper investigates different types of crimped, braided sleeve used for a soft arm for robotic abdominal surgery, with the sleeve required to contain balloon expansion in the pneumatically actuating arm while it follows the required bending, elongation and diameter reduction of the arm. Methods: Three types of crimped, braided sleeves from PET (BraidPET) or nylon (BraidGreyNylon...

There are several methods available for precision cutting of thin metals less than 0.06-inch thick used for these applications, which include materials such as stainless steel, titanium, nickel, and aluminum. The major options, lasers, electric discharge machining (EDM), water-jet, and chemical machining each have a role to play. However, precision fiber laser cutting technology is now emerging...
