Colloidal chemistry is a science to study the physicochemical properties of generalized colloidal dispersion systems. Polymer new comprehensive subject that studies synthesis, chemical reaction, physical chemistry, physics, processing and application polymer compounds. The development mainly experienced four periods: utilization natural polymers, modification production synthetic polymers estab...

Persistent oscillations are a common problem in process plants since they cause excessive variation in process variables and may compromise the product quality. This paper proposes a method for detecting oscillations in non-stationary time series. The method is based on the statistical properties of zero-crossings and it removes the non-stationary trend component from a signal before applying a...

more garbage than any other nationover 160 million tons of garbage each year or more than 1,200 pounds per person. EPA expects this to increase to more than 2,300 pounds of garbage per person each year within the next 1 2 years. Whether it is recycled, buried or burned, the fate of this refuse has major impacts on public health, the environment and the economy. United States citizens generate W...

A new design for permanent, low-cost, and planar fluidic channels on TiO2 nanoparticle coated paperboard is demonstrated. Initially superhydrophobic TiO2 nanoparticle coatings can be converted to hydrophilic by ultraviolet (UVA) light, and fluidic channels can be generated. A simple water treatment after the UVA illumination converts the channels permanent when nanoparticles are removed from th...

In his 19th century novel, Looking Backward, Edward Bellamy described a man who falls asleep in Boston in 1887 and awakens in the year 2000 to find that the United States has evolved into a utopian society. No longer are paper or metallic currency in circulation. Instead people pay for everything with paperboard cards that carry a certain value in dollars. To make a purchase, a person need only...

The press-forming process and the effects of parameter variation on forming have attracted great interest lately. dimensional accuracy formed trays rigidity stability packages are crucial factors for functionality in packaging lines, especially fast operating machinery. torsional stiffness must be at a sufficient level to ensure subsequent processes logistics. objective this study was develop b...

T. J. Urbanik A theory of thin plates which is physically as well as kinematically nonlinear is Research Engineer, developed and used to characterize elastic material behavior for arbitrary stretching Forest Products Laboratory, and bending deformations. It is developed from a few clearly defined assumptions Forest Service, and uses a unique treatment of strain energy. An effective strain conce...

Cellulose fibers come in a wide range of shapes and sizes. The heterogeneity the fiber length, width, wall thickness, curl external fibrillation is detrimental to mechanical performance products such as paper paperboard. Although micro-mechanical models these materials sometimes incorporate features this heterogeneity, so far there no standardized method fully incorporating this. We examine lar...
