Abstract:

Soil profiles are generally heterogeneous and consist of various horizontal layers due to geological processes, the formation of crusts, or other artificial or man-made activities. To quantify infiltration into these heterogeneous soil profiles, the Modified Green-Ampt Model (MGAM) is a physically-based hydrologic model that can efficiently perform under both steady and unsteady rainfall events. Based on the secondary data, this study sought to determine the effect of changing soil layers (soil textures) on infiltration rates and cumulative infiltrations in in both laboratory and field setting

Abstract:

Unbound granular materials (UGM) in permeable pavement will experience large numbers of infiltration during their service-life. The frequently changed moisture not only affects the cooling effect of permeable pavement, but also influences the mechanical behaviors of UGM. However, evidence is lacking to state the influence of infiltration on the behaviors of UGM, which is commonly in fully permeable pavement. Considering the influence of infiltration, this study conducted experimental tests to investigate the effect on the water-retaining and bearing capacity of UGM. With the water-retaining te

The following paper deals with the production of Interpenetrating Phase Composites (IPC) using semi-solid forming technology. Therefore, adequate ceramic foams were selected and infiltrated by processing the aluminium alloy A356 in the semi-solid state. In the studies presented in this paper, the infiltrations of two ceramic materials (Al2O3 and SiC) with three different pore sizes (10, 20 and 30 ppi) were investigated. During the forming process the liquid phase fraction of the aluminium was varied to analyze infiltration effects in relation to the raw material´s liquid phase fraction. Afterw

The pressure infiltration process of porous preforms by molten metals was investigated numerically in this paper.

Abstract Glioblastoma is the most common and malignant type of primary brain cancer with a median patient survival of only 15 months. Tumors are typically categorized into three molecular subtypes—proneural, classical, and mesenchymal—each linked to specific genomic and microenvironmental factors. However, the functional and clinical implications of these subtypes remain poorly understood. Standard treatment involves surgical resection followed by chemotherapy and radiotherapy. Despite this, malignant cells have already at the time point of diagnosis infiltrated healthy brain tissue, driving t

Transient responses to various infiltration events have been examined using an unsaturated flow model. Numerical simulations reveal a range of infiltration patterns which can be related to the ratio of infiltration rate to unsaturated hydraulic conductivity. A high value of this ratio reflects a prevailing hydraulic conductivity which cannot readily redistribute the newly infiltrated moisture. Moisture accumulates in the near-surface region before advancing down through the soil as a distinct wetting front. In contrast, low values of the ratio of rainfall to unsaturated hydraulic conductivity

Abstract:

313 Background: The reported aggregated PET/CT 18F-FDG radiotracer injection infiltration rate from 3 centers in 6 studies is 15.2% (425 infiltrations/2804 patients). Infiltrations can negatively affect cancer patient staging, therapy assessment, treatment planning, and can lead to unnecessary invasive procedures and patient radiation exposure. The radiotracer dose is essential to PET image quality and quantification. Efforts are made to ensure the exact dose administered is used to create the patient image; but, no measures ensure the administered dose completely enters the patient circulatio

Abstract:

Background The impact of infiltrating macrophages on tumor progression in malignant gliomas has been studied extensively. However, there is a lack of animal models for studying the role of infiltrating macrophages in malignant gliomas. Material and methods: The BT4C rat malignant glioma model was characterized by immunohistochemical analysis of inflammatory cell types associated with the tumors. Results BT4C malignant gliomas are highly vascularized tumors with an infiltrative behavior. BT4C gliomas demonstrated a high infiltration rate of macrophages.

Abstract:

Threshold pressure is a very important parameter for melt alloy successfully infiltrating into the porous preform. However, the precise measurement for threshold pressure is very difficult for the reason that infiltration process is undertaken very fast under extreme elevated temperature and high pressure without effective measuring devices to monitor it. A totally new measuring device was proposed and fabricated, which can be used to monitor the infiltration process “visually” and measure the threshold pressure directly at the same time. The infiltration speed can be controlled by adjusting t

Abstract:

PURPOSE: Accurate administration of radiotracer dose is essential to positron emission tomography (PET) image quality and quantification. Misadministration (infiltration) of the dose can affect PET/computed tomography results and lead to unnecessary or inappropriate treatments and procedures. Quality control efforts ensure accuracy of the administered dose; however, they fail to ensure complete delivery of the dose into the patient’s circulation. We used new technology to assess and improve infiltration rates and evaluate sustainability. METHODS: Injection quality was measured, improved, and s

Abstract:

Congenital infiltrating lipomatosis of the face is a rare lesion that comprises a subgroup of lipomatous tumor-like lesions of infancy and childhood. It is characterized by (1) no encapsulation, (2) diffuse infiltration of mature adipose tissue over normal muscle fiber and surrounding structures of face, (3) osseous hyperplasia of subjacent bone, and (4) a high recurrence rate. We report a case of a nine-month-old infant who presented with swelling over right face since birth. Early diagnosis of this lesion provides better surgical approach to control the infiltrative nature of its growth with

Abstract:

Liver resection is a curative treatment for hepatocellular carcinoma (HCC). Tumor-infiltrating leukocytes (TILs) are important players in predicting HCC recurrence. However, the invasive margin could not be confirmed as relevant for HCC. The migration of immune cells into HCC may originate from intratumoral vessels. No previous study has examined perivascular (PV) infiltration. Tumors from 60 patients were examined. Immunohistochemistry was performed against CD3, CD8, CD20, and CD66b. TILs were counted in the PV regions using an algorithm for quantification of the tumor immune stroma (QTiS). T

Unbound granular materials (UGMs) have advantages in their water storage and drainage capabilities in permeable pavement, which is a benefit for urban sustainable development. The plastic strain of UGM is a crucial mechanical property that affects its design and construction. During its service life, repeated load only, repeated load after infiltration, and simultaneous action with load and infiltration are the three inevitable working conditions that will impact plastic strain, especially dynamic water infiltration. How these working conditions influence plastic strain needs to be focused on

Background: Determining the infiltration of carcinomas is essential for the proper follow-up and treatment of cancer patients. However, it continues to be a diagnostic challenge for pathologists in multiple types of tumors. In previous studies (carried out in surgical specimens), the protein COL11A1 has been postulated as an infiltration marker mainly expressed in the extracellular matrix (ECM). We hypothesized that a differential expression of COL11A1 may exist in the peritumoral stroma of tumors that have acquired infiltrating properties and that it may be detected in the small biopsies usua
