We measured the rate of liquid filtration in isolated dog lung lobes inflated to a constant alveolar pressure of 25 cmH2O and with all open vessels filled with plasma. We measured lung weight gain at vascular pressures ranging from 5 to 40 cmH2O relative to pleural pressure. We confirmed that under zone 1 conditions the "arterial" and "venous" extra-alveolar segments have essentially the same filtration characteristics. Using the combined extra-alveolar vascular system, we determined when recruitment of filtration surface area occurred as we increased vascular pressure from 0 to 40 cmH2O. Base

Abstract Affected by groundwater exploitation in the riverside, the infiltration of river water to recharge groundwater will cause changes in the groundwater environment, which has an important impact on the geochemical behavior of arsenic in groundwater. In this study, the groundwater environment zones in the process of river water infiltration were divided, and the arsenic content in groundwater in the study area had a good correlation with the environment zones. In the weak oxidation environment zone and the weak reductive environment zone, as the distance from the riverbank increased, the

We studied the effects of an increase in pulmonary blood flow (PBF) on steady-state lung lymph flow (QL) and protein transport in anesthetized dogs (n = 7) to estimate the effect of vascular recruitment in zone 3 on transvascular filtration. At the end of each experiment, we increased left atrial pressure to 25-30 mmHg using a balloon catheter and obtained a washdown of the lymph protein concentration. PBF was increased with an extracorporeal circuit, which pumped blood from the left to the right atrium, and increases in pulmonary capillary pressure (Pc) were minimized by lowering left atrial

The scope of the presented research included real-time verification of groundwater dynamics in the zone of the filled erosion channel (crevasses) and in the non-transformed zone of the floodplain area during the transition of a flood wave in the river channel. The technical goal was to provide data for the calibration and verification of mathematical model of groundwater flow. For this purpose, automatic recorders of groundwater level and electrical conductivity were installed in the zones selected earlier with the use of DEM.

The drainage- and dewatering-controlling mechanisms in a screw press were detailed in this work. Three pulps (kraft pulp, bleached chemi-thermomechanical pulp, and thermomechanical pulp) were studied to compare a wide range of wood fibre types. The dewatering was controlled by the screw press parameters and the pulps’ properties. Filtration was found to be the controlling mechanism in the first part of the screw press for the three pulps, and it was less important when the fines content was greater. In the compression zone, the degree of compression was affected by the pulp flexibility and the

Abstract Methods of numerical modelling have helped to carry out the research of coupled processes of rock deformation around a gate road with methane drainage boreholes and methane filtration in terms of applying different techniques of its protection. The following has been shown: without the use of protective structures, underworked drainage boreholes are broken and stop functioning. If the protective structures are used, the rock-bolting beam above the mined-out space becomes stable. Boreholes go beyond the zones of inelastic deformations and remain in their operating conditions even after

An oil filter is a necessary and significant part of many manufacturing processes and equipment. Unlike the structural design and filter material selection, the particle movement in the filter during filtration is the fundamental factor influencing the filter’s performance, but this has not attracted enough attention. Due to the small size and large number of particles in the filter, it is difficult to monitor every particle’s movement. Therefore, this work used a hydraulic oil filter as a case study.

In well drilling operations, interactions between drilling fluid water-based and the well-bore present significant challenges, often escalating project costs and timelines. Particularly, fractures (both induced and natural) and permeable zones at the wellbore can result in substantial mud loss or increased filtration. Addressing these challenges, our research introduces a novel coupled numerical model designed to precisely calculate fluid losses in fractured and permeable zones. For the permeable zone, fundamental variables such as filtration velocity, filtrate concentration variations, permea

Abstract During drilling operations, mud is typically circulated at pressures above the reservoir pressure, and this causes solid particles to deposit along the wellbore creating a mud cake, while the mud filtrate can invade into the formation creating a damaged zone. Near wellbore damage can result in reduced permeability, increased skin and thereby lower productivity of the reservoir, while thick mud cakes can cause issues during drilling including stuck pipe, high torque as well as excessive swab and surge pressures during tripping. These can be prevented by designing the drilling fluid to

Today, it is common practice to produce oil from failure-prone, weakly cemented reservoirs. The operators’ desire to increase production requires operating wells at their maximum capacity, and therefore leads to more aggressive drainage of the reservoirs with high oil flow from the pay zone to the well bore. At the same time, the oil filtration rate increases significantly, especially in the near well bore zone. This promotes the active movement of rock particles together with the production from the bottomhole formation zone to the well bore. Sand movement to the well bore and removal into th

Abstract During waterflooding, suspend solids are usually contained in the injected water, which may gradually block pores and cause formation damage after flowing into a formation and being trapped there. Water treatment is usually conducted on the surface to reduce TSS (Total Suspended Solids) before being injected. However, to what extent the TSS should be controlled depends on specific water injection conditions and there are no methods in industry to quantitatively evaluate it. Meanwhile, the corrections between the injection parameters and the extent of formation damage are not clear. In
