بررسی رفتارخاکهای ماسه ای مسلح و غیر مسلح زیر پی نواری به کمک روش PIV [PDF]

مهندسی عمران فردوسی, 2012
در تحقیق حاضر مکانیسم گسیختگی، تغییر شکل خاک ماسه ای و تاثیر مسلح کننده ها بر این فرآیند در زیر یک پی نواری به کمک روش PIV بررسی شده است. بدین منظور مدلسازی‌های فیزیکی بر روی خاک ماسه‌ای انجام شده و برای مسلح سازی از مواد ژئوسنتتیکی مناسب استفاده گردیده

Dimension conservation for self-similar sets and fractal percolation [PDF]

, 2014
We introduce a technique that uses projection properties of fractal percolation to establish dimension conservation results for sections of deterministic self-similar sets.

Essential work, invisible workers: The role of digital curation in COVID‐19 Open Science

Journal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 703-717, April 2025.
Abstract In this paper, we examine the role digital curation practices and practitioners played in facilitating open science (OS) initiatives amid the COVID‐19 pandemic. In Summer 2023, we conducted a content analysis of available information regarding 50 OS initiatives that emerged—or substantially shifted their focus—between 2020 and 2022 to address ...

Validation of the granular temperature prediction of the kinetic theory of granular flow by particle image velocimetry and discrete particle model [PDF]

, 2004
In order to give a detailed description of the hydrodynamics in large industrial scale fluidized beds, continuum models are required. Continuum models often use the kinetic theory of granular flow (KTGF) to provide closure equations for the internal ...

Painleve equations from Darboux chains - Part 1: P3-P5

, 2003
We show that the Painleve equations P3-P5 can be derived (in a unified way) from a periodic sequence of Darboux transformations for a Schrodinger problem with quadratic eigenvalue dependency.

Opposing consensus science through scholarly practices: The role of claims maintenance

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Prognostic Effect of pan-Immune-Inflammation Value Indices in Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention

Clinical and Applied Thrombosis/Hemostasis
Background This study aimed to investigate the association of pan-immune-inflammation value (PIV), PIV/HDL-C (high-density lipoprotein cholesterol), PIV*LDL-C (low-density lipoprotein cholesterol) with the prognosis of patients with acute coronary ...

Treatment of biodiesel wastewater using ferric chloride and ferric sulfate [PDF]

, 2017
The production of biodiesel through the transesterification method produces a large amount of wastewater that contains high level of chemical oxygen demand (COD) and oil and grease. In this study, coagulation was adopted to treat the biodiesel wastewater.

Single and multiphase CFD approaches for modelling partially baffled stirred vessels: comparison of experimental data with numerical predictions [PDF]

, 2007
Whilst the use of CFD to study mixing vessels is now common-place, there are still many specialised applications that are yet to be addressed. Here we present CFD and PIV results for a hydrodynamic study of a partially baffled vessel with a free surface.
