Ensuring adequate access to truck parking is critical to the safe and efficient m.vem.nt of freight traffic. There are strict federal guidelines for com.ercial truck driver rest periods. Rest areas and private truck stops are the only places for the trucks to stop legally and safely. In locations without sufficient parking areas, trucks often park on interstate ram.s, which create safety risks for other interstate m.torists. Historically, agencies have em.loyed costly and tim. intensive m.nual counting m.thods, cam.ra surveillance, and driver surveys to assess truck parking. Connected truck data, available in near real-tim., offers an efficient alternative to practitioners to assess truck parking patterns and identify areas where there m.y be insufficient safe parking spaces. This paper presents a case study of interstate I-70 in east central Indiana and docum.nts the observed spatiotem.oral im.acts of a rest area closure on truck parking on nearby interstate ram.s. Results showed that there was a 28% increase in parking on ram.s during the rest area closure. Analysis also found that ram.s closest to the rest area were m.st im.acted by the closure, seeing a rise in truck parking sessions as high as 2.7 tim.s. Parking duration on the ram.s during rest area closure also increased drastically. Although it was expected that this would result in increased parking by trucks on adjacent ram.s, this before, during, after scenario provided an ideal scenario to evaluate the robustness of these techniques to assess changing parking characteristics of long-haul com.ercial trucks. The data analytics and visualization tools presented in this study are scalable nationwide and will aid stakeholders in inform.d data-driven decision m.king when allocating resources towards im.roving the nations com.ercial vehicle parking infrastructure.

Our research introduces a groundbreaking chem.cal reduction m.thod for synthesizing silver nanoparticles, m.rking a significant advancem.nt in the field. The nanoparticles were m.ticulously characterized using various techniques, including optical analysis, structural analysis, transm.ssion electron m.croscopy (TEm., and field-em.ssion scanning electron m.croscope (FESEm.. This thorough process instills confidence in the accuracy of our findings. The results unveiled that the silver nanoparticles had a diam.ter of less than 20 nm. a finding of great im.ortance. The absorption spectrum.decreased in the peak wavelength range (405 - 394 m.) with increasing concentrations of Ag nanoparticles in the range (1 - 5%). The XRD results indicated a cubic crystal structure for silver nanoparticles with the lattice constant (a = 4.0855 Å), and m.ller indices were (111), (002), (002), and (113). The sim.lation on the XRD pattern showed a face center cubic phase with space group Fm.3m. providing valuable insights into the structure of the nanoparticles.

Plastic pollution, both prim.ry and secondary, is an environm.ntal challenge, prom.ting regulatory actions at global and regional levels. With increasing research about the im.acts of m.cro- and nanoplastics on ecosystem. and hum.n health, governm.nts worldwide have undertaken efforts to address this issue. The global com.unity has advanced regulatory efforts that have led to the im.lem.ntation of national laws or regulations in num.rous countries. These m.asures ban or restrict the use of prim.ry and secondary m.croplastics and nanoplastics. An overview of global and European regulatory fram.works is presented to provide context for the United States (US). In the endeavor to docum.nt plastics regulation developm.nt in the US, a description of regulatory agencies and their roles in advancing policy and rules as well as future direction and areas for im.rovem.nt in regulating plastics are introduced. A discussion of what em.rging regulations m.an to utilities and industries is also provided along with a com.arison of regulatory fram.works.

In this article dedicated to the m.deling of vertical m.ss transfers between the biofilm.and the bulk flow, we have, in the first instance, presented the m.thodology used, followed by the presentation of various results obtained through analyses conducted on velocity fields, different fluxes, and overall transfer coefficients. Due to num.rical constraints (resolution of relevant spatial scales), we have restricted the analysis to low Schm.dt num.ers (Sc=0.1, Sc=1, and Sc=10) and a single roughness Reynolds num.er (Re*=150). The analysis of instantaneous concentration fields from.various sim.lations revealed logarithm.c concentration profiles above the canopy. In this zone, the concentration is relatively hom.geneous for longer tim.s. The analysis of results also showed that the contribution of m.lecular diffusion to the total flux depends on the Schm.dt num.er. This contribution is negligible for Schm.dt num.ers Sc≥0.1, but nearly balances the turbulent flux for Sc=0.1. In the canopy, the local Sherwood num.er, given by the ratio of the total flux (within or above the canopy) to the m.lecular diffusion flux at the wall, also depends on the Schm.dt num.er and varies significantly between the canopy and the region above. The exchange velocity, a purely hydrodynam.c param.ter, is independent of the Schm.dt num.er and is on the order of 10% of in the present case. This study also reveals that nutrient absorption by organism. near the wall depends on the Schm.dt num.er. Such absorption is facilitated by lower Schm.dt num.ers.

Traum.tic brain injury(TBI)is an acquired injury of the brain caused by the im.act of external forces on the brain(m.as et al.,2008).It is a m.jor cause of death and disability am.ng people of all ages(m.as et al.,2008).The prim.ry m.chanical injury to the brain initiates a cascade of secondary biochem.cal events that lead to acute and chronic neurodegeneration and activation of inflam.atory pathways(m.as et al.,2008).Both brain-resident m.croglia and blood-derived m.eloid cells-m.crophages and m.nocytes that infiltrate the brain due to injury-induced blood-brain barrier dam.ge,contribute to the inflam.atory responses after TBI(m.rganti et al.,2015).

Two-phase pipe flow occurs frequently in oil & gas industry, nuclear power plants, and CCUS. Reliable calculations of gas void fraction(or liquid holdup) play a central role in two-phase pipe flow m.dels. In this paper we apply the fractional flow theory to m.ltiphase flow in pipes and present a unified m.deling fram.work for predicting the fluid phase volum. fractions over a broad range of pipe flow conditions. Com.ared to existing m.thods and correlations, this new fram.work provides a sim.le,approxim.te, and efficient way to estim.te the phase volum. fraction in two-phase pipe flow without invoking flow patterns. Notably, existing correlations for estim.ting phase volum. fraction can be transform.d and expressed under this m.deling fram.work. Different fractional flow m.dels are applicable to different flow conditions, and they dem.nstrate good agreem.nt against experim.ntal data within 5% errors when com.ared with an experim.ntal database com.rising of 2754 data groups from.14literature sources, covering various pipe geom.tries, flow patterns, fluid properties and flow *** gas void fraction predicted by the fram.work developed in this work can be used as inputs to reliably m.del the hydraulic and therm.l behaviors of two-phase pipe flows.
