Zoning of groundwater contaminated by Nitrate using geostatistics method (case study: Bahabad plain, Yazd, Iran) [PDF]
Desert, 2014 Groundwater quality management is one of the most important issues in many arid and semi-arid regions, including Iran.Nitrate (NO3-) is one of the most common anions contaminating groundwater.

Generalized Lattice Gauge Theory, Spin Foams and State Sum Invariants [PDF]
, 2001 We construct a generalization of pure lattice gauge theory (LGT) where the role of the gauge group is played by a tensor category. The type of tensor category admissible (spherical, ribbon, symmetric) depends on the dimension of the underlying manifold (

Risk assessment using IEUBK model for the Naica mine tailings
Environmental Progress &Sustainable Energy, EarlyView.Abstract Mexico has a long history of mineral extraction, during which limited environmental regulations allowed the accumulation of toxic waste near communities, primarily in rural or undeveloped areas. Some of these toxic substances, such as lead, pose significant risks to vulnerable populations, particularly children aged 0 to 7 years.

Damage location method for thin composites structures - application to an aircraft door [PDF]
, 2013 Piezoelectric sensors are widely used for Structure Health Monitoring (SHM) technique due to their high-frequency capability. In particular, electromechanical impedance (EMI) techniques give simple and low cost solutions for detecting damage in composite

Weak gravitational lensing with DEIMOS [PDF]
, 2011 We introduce a novel method for weak-lensing measurements, which is based on a mathematically exact deconvolution of the moments of the apparent brightness distribution of galaxies from the telescope's PSF.

International Journal of Climatology, EarlyView.The graphical abstract presents observed (1963–2023) and projected changes in hydroclimatic extremes in Rio Grande do Norte, Brazil. It integrates dry‐spell duration (CDD) and extreme precipitation (R95pTOT) using CMIP6 multimodel ensembles under SSP1‐2.6, SSP2‐4.5, and SSP5‐8.5.

A classical approach to TQFT's [PDF]
, 2002 We present a general framework for TQFT and related constructions using the language of monoidal categories. We construct a topological category C and an algebraic category D, both monoidal, and a TQFT functor is then defined as a certain type of ...
