Summary: Spatial Filter Velocimetry (SFV) is utilized to monitor and control agglomeration processes, analyzing the impact of operating conditions and proposing a new approach to delineate stages in fluidized bed agglomeration based on particle size classes obtained from SFV probe data.

Summary: This study investigates the impact of droplet breakup and coalescence processes on droplet size distribution in annular flow. The influence of these processes is reflected in four factors: breakup-induced droplet birth, breakup-induced droplet death, coalescence-induced droplet birth, and coalescence-induced droplet death. These four effects collectively shape the probability density distribution of droplet size after reaching a dynamic equilibrium. A numerical procedure is developed to calculate the droplet size distribution and characteristic droplet sizes using microscopic mechanisms of droplet breakup and coalescence, and the predictions are validated against experimental data.

Summary: This study successfully recycled nanoparticles from wastewater using foam fractionation and developed a novel method to enhance foam drainage for improving nanoparticle recovery rate. The efficiency of nanoparticle recycling was found to be influenced by their shapes and structures, with tubular nanoparticles showing higher recovery rates than spherical nanoparticles.

Summary: Foam fractionation was used to remove P. aeruginosa from aqueous solution, with a novel strategy developed to strengthen foam drainage by inducing foam evolution. By increasing the size difference among adjacent bubbles, gas diffusion and bubble coarsening were significantly promoted, contributing to the removal of microbial contamination effectively.

Summary: Measurement of allele frequency shifts between temporally spaced samples has been used to estimate effective population size (N-e), also known as variance effective size (N-eV). Our study reveals that N-eV of a local population within a sub-structured population is influenced by genetic drift, migration rate (m), and census size (N-c). The relationship between N-e and N-c determines whether the realized N-eV of a local population increases or decreases with increasing m. The effect of N-c on N-eV is most significant at higher migration rates.

Summary: Soil bacterial communities in a coastal area follow a distance-decay relationship and the distribution is influenced by body size. This study collected soil samples from two adjacent ecosystems and found that the entire microbial community, as well as individual taxonomic groups, exhibited distance-decay patterns. The turnover rate of microbial communities was higher in nontidal soils and topsoil, with body size influencing the spatial limitation in nontidal topsoil but not in tidal soils.

Summary: The study examines the aerosol optical properties in the Western Mediterranean Sea using POLDER-3 data, showing a significant influence of North African desert dust on the region. The spatial distribution and seasonal cycles of both total and coarse-mode aerosol optical depth are largely controlled by this desert dust. The study also reveals a decreasing trend in fine-mode aerosol optical depth over the period of 2005-2013, potentially related to reduced emissions in surrounding European countries.

Summary: This study examines the evolution of variance and entropy in granule size during the fluidized bed agglomeration process using two different aggregation kernels. The first kernel allows unconstrained agglomeration process, leading to the fastest and largest increase in variance and entropy. The second kernel includes a growth-limiting mechanism, which significantly reduces both variance and entropy. It is shown that entropy provides a better measure of size evolution than variance as it represents the changing shape of the distribution more closely.

Summary: The optical properties of colored dissolved organic matter (CDOM) in the upper water of the western Arctic Ocean were studied. The study found a decoupling effect between CDOM concentration and biological productivity, and an increase in DOM molecular weight with salinity. Four fluorescent components were identified, with C3 and C4 components being associated with Pacific water inflow.

Summary: The local bubble size distribution and Sauter mean diameter in bubble columns are influenced by the lift force and parameters in the class method, rather than the radial positions. Including lift force and increasing the minimum and maximum bubble diameters can improve the prediction accuracy of bubble size distribution.

Summary: This paper examines the city size distribution in Spain from a new perspective, focusing on the influence of distance. The study reveals that the Pareto distribution is validated in most cases regardless of city size, while the lognormal distribution is valid at short distances.

Summary: This study investigated the feasibility of electrostatic demulsification for O/W emulsions, focusing on enhancing demulsification efficiency by adjusting parameters such as voltage, frequency, water content, and retention time. Results showed that applying a pulsed electric field was an effective technology for promoting the coalescence of emulsified oil droplets, leading to improved oil separation efficiency.

Summary: This study investigated the spatial variation and stability mechanisms of soil organic carbon (SOC) in tropical montane forests, showing that terrain, particularly convexity, plays a crucial role in influencing the distribution and accumulation of SOC. Terrain had a significant impact on the spatial variations in SOC, with convexity explaining the distribution of SOC and its physical stability fractions (HFC) best.

Summary: Outliers with highly superior performance are valuable in plants breeding. This study aimed to investigate their behavior and distribution in populations. The results showed that outliers exhibit a predictable pattern in populations but are rare due to small population sizes used in breeding. The parental characteristics were found to be indicative of the best chances of getting progeny with extreme performance. Additionally, a slight upward bias was observed when applying the usefulness criterion to the extreme upper tails of the population.
