the commercial profile of the amoco cd mgcl2 supported polypropylene catalyst is presented. the development, the unique method of preparation/production, with emphasis on particle morphology, and the parameters affecting particle size (ps), particle size distribution (psd), and particle shape are discussed in detail. the outstanding performance of the catalyst, tailoredmade for the amoco-chisso...

Paracetamol crystals often exhibit poor compressibility properties, which results in capping issues. The Particle Size Distribution (PSD) of paracetamol was engineered to improve the crystals. This accomplished by growing presence additives. active pharmaceutical ingredient Phenacetin and impurity 4-chloroacetanalide were used modify crystal properties paracetamol. In solution, phenacetin or mo...

Soil pore size and arrangement control the heterogeneous distribution of nutrients, water, air and, therefore, are likely a superimposed integrated factor dictating soil microbial community structure. It is known that with more large pores can potentially harbor diverse microbes under low hydraulic connectivity. Still, there scant information on how (PSD) governs composition association communi...

Particle Size Distribution (PSD) is one of the prime guiding factors granular media response. Degradation via weathering a process, which brings about gradual shift in PSD. In nature, chemically sensitive material like calcite undergoes chemo-mechanical degradation bringing variations their behaviour. present study, an experimental investigation carried out to get insight into mechanical respon...

Common Carp Cyprinus carpio and Bigmouth Buffalo Ictiobus cyprinellus are widespread across the Midwest, where they can achieve high population densities in shallow lakes. Despite their contrasting statuses as invasive native fishes, these species commonly managed together due to capacity have deleterious effects on water quality. However, intra-annual sampling variability is poorly understood ...

OBJECTIVE To evaluate the Humphrey visual field parameters in patients with pituitary adenoma and classify the visual field defects in this patient group. METHODS Forty primary pituitary adenoma patients underwent neuro-ophthalmological examination and Humphrey Perimetry 30-2 visual field test at Baskent University, Departments of Ophthalmology, and Neurosurgery, between 2003 and 2005. Global...

The different expressions of NR2 and synaptic-associated proteins have been studied by protein and mRNA level with immunoblotting, in situ hybridization, or immunogold analysis. But the relationship between NR2 subunits and PSD-95 family proteins is still controversial. In this study, we used immunofluorescent staining to assess NR2B and PSD-95 expressions and the relationship between them in C...

BACKGROUND Mixing is an energy demanding process which has been previously shown to affect enzymatic hydrolysis. Concentrated biomass slurries are associated with high and non-Newtonian viscosities and mixing in these systems is a complex task. Poor mixing can lead to mass and/or heat transfer problems as well as inhomogeneous enzyme distribution, both of which can cause possible yield reductio...

a study of the atmospheric particulate size distribution of total suspended particulate matter(tspm) and associated heavy metals concentrations has been carried out for the urban part of sarajevo city,bosnia and herzegovina. urban particles (n=150) were collected using a high volume air sampler equippedwith a 6-stage impactor. apart from fe which has been determined by flame atomic absorption s...

dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for ress (rapid expansion of supercritical solution) process. supercritical co2 was used as solvent and ibuprofen was applied as the model component in all runs. the resulting ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by sem and laser diffraction particle size ana...
