A review of the literature reveals potential advantages that papermakers can achieve by placing minerals in the lumens or cell walls of fibers before the pulp is formed into paper. Loading of filler into the fiber lumen by mechanical deposition or within the cell wall by in-situ precipitation has been reported to generally result in a moderate reduction in light scattering coefficient and incre...

The deposition of thin films bioactive materials is the most common approach to improve bone bonding ability an implant surface. With this purpose, several wet and plasma assisted methods were proposed in scientific literature. In review, we considered obtained by nanosecond Pulsed Laser Deposition (PLD). Since hydroxyapatite (HA) has composition structure similar that mineral component bone, i...

The tendons in the turkey leg have specific well-defined areas which become mineralized as the animal ages and they are a thoroughly characterized model system for studying the mineralization process of bone. In this study, nondestructive Raman spectroscopic analysis was used to explore the hypothesis that regions of the turkey tendon that are associated with mineralization exhibit distinct and...

This study focuses on explaining variations in real constant-quality house prices in jurisdictions located in multiple MSAs. Using a hedonic house price framework, we test competing theories of house price determination. Using two variants of the random coefficients model, we find that public school quality has a very large impact on real constant-quality house prices. Our results suggest that ...

The agro-climatic environments in subtropical islands around Japan were analyzed by using meteorological data (average for 1971–2000). This study found that the horizontal distribution of monthly mean temperatures in both the subtropical islands and Japan’s main islands can be expressed accurately as a function of latitude for all seasons. These relationships cannot be applied to the monthly me...

The process of mineral formation following periods of growth interruption (growth bands) is described. Flat pearl implantation as well as a new trepanning method are used to observe the transitory phases of calcium carbonate which nucleate and grow during this process. An initial random nucleation of the aragonite polymorph is observed followed by a transition towards spherulitic growth. During...

Biowaste composting at several plants in Scandinavia has been troubled by low pH in the collected waste as well as after the composting process. Our hypothesis was that increased aeration would give a higher and faster rise in pH during the composting process, and that this would give a higher decomposition rate. The objective was to test this hypothesis by experiments in full scale, with an em...

Processes that occur in clouds cover a wide range of spatial scales, from micrometers in the condensation and evaporation of individual cloud droplets through a few hundred meters in the case of fair weather cumulus clouds up to several hundred kilometers for the cloud systems associated with extratropical baroclinic systems. In order to describe the main effects clouds have on the atmosphere a...

Tendon attaches to bone across a functionally graded interface, "the enthesis". A gradient of mineral content is believed to play an important role for dissipation of stress concentrations at mature fibrocartilaginous interfaces. Surgical repair of injured tendon to bone often fails, suggesting that the enthesis does not regenerate in a healing setting. Understanding the development and the mic...
