In the recent years, we have witnessed a growing consumption of carbonated beverages like soft drinks and beer, marketed in attractive containers and packaging. Technology has certainly played its part in the increased consumption of carbonated beverages with the adventof glass bottles, cans, plastic bottles, high speed packaging lines and evolving packaging systems. Packaging carbonated produc...

Recyclable cellulose nanofibril (CNF) and lignin-containing (LCNF) coated wood flour composites were fabricated using a vacuum-filtration process for food serving applications. The had excellent mechanical, oil, grease barrier properties compared to commercial container. However, the with both LCNF CNF coating layers poor performance in wet conditions addition of 1 wt.% aluminum sulfate (alum) ...

A finite element (FE) model of a 1998 Audi Model A8 has been developed for the crash analysis associated with the NHTSA NCAP program. The AUDI model A8 is an all aluminum four-door passenger vehicle; it is classified as a ‘large sedan’ car. The model developed is to be used to analyze frontal impact against a rigid barrier as specified in standard procedures associated with the assessment of pa...

The equilibrium and fluctuations of an ideal gas in a rigid container are studied by every student statistical mechanics. Here, we examine the less well-known case when box is floating freely; particular, determine velocity position due to interactions with it contains. This system toy model for black hole surrounded stars at center galaxy. These may be observable nearby galaxies.

Liquid storage cylindrical containers are built for storing a variety of liquids. The seismic behavior of tanks is, however, quite complex problem. The interaction of tank and liquid can be simplified with the concept of generalized single-degree-of-freedom systems representing the convective, rigid impulsive and flexible impulsive vibration modes. This paper presents the theoretical background...

In this thesis we consider a three-dimensional packing problem arising in industry. The task is to pack a maximum number of rigid boxes with side length ratios of 4 : 2 : 1 into an irregularly shaped container. Motivated by the structure of manually constructed packings so far, we pursue a discrete approach. We discretize the shape of the container as well as the set of possible box placements....

Beryllium is the fourth element in the periodic table and the second lightest metal known. Discovered as an oxide in 1798 by the French chemist L. N. Vauquelin, beryllium was first isolated in 1828, when it was called "glucinium" owing to the sweet taste of its salts. Beryllium is the lightest of all solid, chemically stable substances and has an unusually high melting point (12870C). Silver gr...

Rigid metallic fiber structures made from a variety of different metals and alloys have been investigated mainly with regard to their functional properties such as heat transfer, pressure drop, or filtration characteristics. With the recent advent of aluminum and magnesium-based fiber structures, the application of such structures in light-weight crash absorbers has become conceivable. The pres...
