We investigated the effects of CO2 enrichment on fine root chemical composition of two tree species common to northern hardwood forests. Two-year-old Betula papyrifera and 3-year-old Acer saccharum saplings were grown under ambient (400 μmol·mol–1) and elevated (700 μmol·mol–1) CO2 in a glasshouse experiment. In both species, root/shoot ratios and fine root percentages (of total biomass) were u...

The paper presents the test results from investigation of nature and mechanical behaviour mudbricks ancient mudbrick wall Eleusis in Attica, Greece. remains preserved to date site are some largest Small fragments were taken laboratory for experimental investigation. Testing included index tests toclassify soil material made of, mineralogical analyses their fines’ content, testing suitable mater...

Multi-use marine parks achieve conservation through spatial management of activities. Zoning of marine parks in New South Wales, Australia, includes high conservation areas and special purpose zones (SPZ) where maritime activities are concentrated. Although such measures geographically constrain anthropogenic impacts, we have limited understanding of potential ecological effects. We assessed se...

In this paper design and fabrication of compact fluidized bed gasifier with increased gas – solid interaction is proposed for automotive vehicle. The aim of the design is generate a nitrogen (N2) free product gas with low tars and fines content. Firstly a compact size gasifier with fluidized bed is designed and after that it fabricated. Design was done with the help of CATIA design/modeling sof...

The study investigates ibuprofen with wax-like properties as a multifunctional agent (as an active component and as a melt binder). Binding efficiency was compared with granules prepared by wet granulation using polyvinylpyrollidone (PVP K-30) as a binder for micromeritic, physical and mechanical properties such as angle of repose, particle size distribution Carr's index, Hausner's ratio, crush...

A sampling protocol was developed to examine particles released from granular activated carbon filter beds. A gauze filter/Swinnex procedure was used to collect carbon fines from 201 granular activated carbon-treated drinking water samples over 12 months. Application of a homogenization procedure (developed previously) indicated that 41.4% of the water samples had heterotrophic plate count bact...

Response surface methodology was used with four factors to screen for the best starch and optimize the use of chemicals in order to maximize precipitated calcium carbonate (PCC) filler retention in a peroxidebleached TMP suspension. Three commercial starches were used in conjunction with colloidal silica and flocculant. The PCC loading level and the interactions between PCC level, starch, flocc...
