Single-particle analysis and electron tomography

Both single-particle analysis and electron tomography are special tools for the structural analysis of biological components by transmission electron microscopy. Single-particle analysis enables us to determine the structures of relatively large proteins and macromolecular complexes without crystallisation. Electron tomography is often used to visualise organelles and subcellular structures at ...

Oil Analysis for Hydraulic Systems

Hydraulic systems are used in industrial, mobile and aviation applications to transmit power to operate equipment. They are incredibly efficient, compact, and lightweight relative to a mechanical equivalent. Hydraulic fluids transmit force in the system, and as such are carefully chosen by the system maker. Chemical stability, high flash and fire points, viscosity, and oxidation resistance are ...

Particle removal in a novel sequential mechanical filter system loaded with blackwater

A novel sequential mechanical filter system was developed as an alternative primary treatment method for onsite wastewater treatment. The filter combines traditional screening with a novel type of counter-flow filter using wood-shavings as a biodegradable filter matrix. This study tested the system in a batch loading regime simulating high frequency toilet flushing using blackwater from a ...

Using sediment particle size class analysis to better understand urban land-use effects

Abstract A nested-scale experimental watershed study design was used to demonstrate rainfall-runoff and sediment particle size class variability in a representative urbanizing watershed in central Missouri USA. On average, sediment particle size classes were almost twice as large (2.0 to 500um size range) in headwaters, relative to an urban setting. Eighty percent of total sediment in ...

An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

Observation based analysis for the determination of equilibrium time constant between ammonia, acid gases, and fine particles

Experimental measurements of ammonia, acid gases, and the inorganic components of atmospheric aerosols were made at a commercial hog farm in eastern North Carolina from May 1998 to June 1999 by an annular denuder system (ADS). The ADS consisted of a cyclone separator, one diffusion denuder coated with sodium carbonate, another diffusion denuder with citric acid, and a filter pack containing ...

Comparison of digital and manual methods of snow particle size estimation

Maintaining long time series of observations of the Cryosphere is a key issue in climate research. Long observational time series involve problems due to change in methodology or observers. In order to extend time series and introduce new methods, careful comparisons must be made to ensure homogeneity in the observational data. We have compared an established method for snow grain-size ...

Granulometric Evaluation of Particle Size Using Suspension Pressure During Sedimentation

A new method, computerized granulometric analysis in suspension (C-GRAINS), is suggested for the sedimentation analysis of soil particles based on the relation between the specific weight and liquid pressure of a soil suspension. Theoretical aspects concerning this new testing method are discussed, and a prototype C-GRAINS system is fabricated accordingly. The general behavior of the new system ...

Flocculation performance of magnetic particles with high-turbidity surface water

The sharp increase in raw-water turbidity following heavy rain presents considerable treatment problems due to low sedimentation rates. The objective of this study was to evaluate the removal of negatively charged suspended solids (SS) in surface water treatment using magnetic particles (nFeO; FeO · Fe2O3) synthesised in our laboratory. The performance of nFeO in removing ...

Noncovalent immobilization of streptavidin on in vitro- and in vivo-biotinylated bacterial magnetic particles

Biotinylated magnetic nanoparticles were constructed by displaying biotin acceptor peptide (BAP) or biotin carboxyl carrier protein (BCCP) on the surface of bacterial magnetic particles (BacMPs) synthesized by Magnetospirillum magneticum AMB-1. BAP-displaying BacMPs (BAP-BacMPs) were extracted from bacterial cells and incubated with biotin and ...

Particle retention in compact constructed wetlands treating highway stormwater

Three pilot-scale compact constructed wetland systems were constructed to treat stormwater from a highway. They each comprised a sedimentation tank, and a vertical flow (VF) wetland bed equipped with a recirculation device. The VF wetland beds were filled with woodchip, pumice and volcanic gravel, respectively. According to the analysis of the particle size distributions (0.52–500 ...
