• Properties and Formation of Mineralized Veins in an Organic-Rich Shale Formation

  Publikacja

  • A. Małachowska
  • S. Green
  • J. Hupka

  - Rok 2017

  An earlier paper defined mineral and organic matter constituents in weak interfaces in shale formations (Ptaszynska, et. al., 2016). The formation studied in the earlier work and here is the Jurassic, early-Cretaceous Vaca Muerta formation in the Neuquen basin in Argentina. In this earlier work, mineralized "veins" were noted to be prevalent and complicated, sometimes being shear weak interfaces while in other cases they were not....

• An isogeometric finite element formulation for boundary and shell viscoelasticity based on a multiplicative surface deformation split

  Publikacja

  • K. Paul
  • R. Sauer

  - INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING - Rok 2022

  This work presents a numerical formulation to model isotropic viscoelastic material behavior for membranes and thin shells. The surface and the shell theory are formulated within a curvilinear coordinate system,which allows the representation of general surfaces and deformations. The kinematics follow from Kirchhoff–Love theory and the discretization makes use of isogeometric shape functions. A multiplicative split of the surface...

• Bending and buckling formulation of graphene sheets based on nonlocal simple first-order shear deformation theory

  Publikacja

  • H. R. Majidi

  - Materials Research Express - Rok 2018

  This paper presents a formulation based on simple first-order shear deformation theory (S-FSDT) for large deflection and buckling of orthotropic single-layered graphene sheets (SLGSs). The S-FSDT has many advantages compared to the classical plate theory (CPT) and conventional FSDT such as needless of shear correction factor, containing less number of unknowns than the existing FSDT and strong similarities with the CPT. Governing...

• Formation of acoustic field in rooms

  Publikacja

  • K. Leo

  - Archives of Acoustics - Rok 2011

  Paper describes known form literature method of sound diffusity index assesment, which utilizes impulse response of the room. Process of froming diffused sound field using this method was investigated.Increase of sound diffusity index in time was noted in rooms differing in shape,volume and reverberation time. Exponential growth of sound diffusion index was noted which correlates with other acoustical rooms measures.

• FORECASTING BIOGAS FORMATION IN LANDFILLS

  Publikacja

  • Z. Kneba
  • J. Kropiwnicki
  • J. Hadrzyński
  • M. Ziółkowski

  - Acta Mechanica et Automatica - Rok 2023

  : The aim of the present research was to develop a mathematical model for estimating the amount of viscous gas generated as a function of weather conditions. Due to the lack of models for predicting gas formation caused by sudden changes in weather conditions in the literature, such a model was developed in this study using the parameters of landfills recorded for over a year. The effect of temperature on landfill gas production...

• TBAF Promoted Formation of Symmetrical Trisulfides

  Publikacja

  • S. Lach
  • D. Witt

  - HETEROATOM CHEMISTRY - Rok 2014

  We have developed a new method for the synthesis of functionalized symmetrical trisulfides based on (5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorin-2-yl)disulfanyl derivatives prepared from readily available 5,5-dimethyl-2-sul-fanyl-2-thioxo-1,3,2-dioxaphosphorinane or bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl) disulfide. The symmetrical trisulfides can be obtained from aliphatic and aromatic thiols andL-cysteine derivatives...

• Agile Methods In Formation of Metropolis Neighbourhood

  Publikacja

  • J. Małuj
  • D. Załuski

  - Rok 2017

  A study of the zone adjoining the metropolis area of Tricity (Poland) was conducted on the basis of analyses of changes in spatial development, outline planning decisions and local plans of spatial development. Localities placed at several dozen kilometres from strongly urbanized areas do not constitute metropolis outskirts. The vicinity of large urban centres is an obstacle to the development of localities as self-sufficient units...
