EFFECT OF MINIMUM QUANTITY LUBRICATION ON SURFACE ROUGHNESS IN TOOL-BASED MICROMILLING

open access: yesInternational Islamic University Malaysia Engineering Journal, 2017
Cutting fluid plays an important role in machining processes to achieve dimensional accuracy in reducing tool wear and improving the tool life. Conventional flood cooling method in machining processes is not cost effective and consumption of huge amount ...

Black holes from multiplets of scalar fields in 2+1- and 3+1-dimensions

open access: yes, 2016
We obtain classes of black hole solutions constructed from multiplets of scalar fields in 2+1 / 3+1 dimensions. The multi-component scalars don't undergo a symmetry breaking so that only the isotropic modulus is effective.

A methodology for the lightweight design of modern transfer machine tools [PDF]

open access: yes, 2018
This paper deals with a modern design approach via finite elements in the definition of the main structural elements (rotary table and working unit) of an innovative family of transfer machine tools. Using the concepts of green design and manufacture, as

Supersymmetric particle mass measurement with invariant mass correlations

open access: yes, 2009
The kinematic end-point technique for measuring the masses of supersymmetric particles in R-Parity conserving models at hadron colliders is re-examined with a focus on exploiting additional constraints arising from correlations in invariant mass ...

Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids

open access: yesMetalMat, EarlyView.
This study experimentally evaluates the performance of eco‐friendly vegetable‐based cutting fluids—coconut, sunflower, and palm oils—during turning of AISI 304 stainless steel under minimum quantity lubrication. Palm oil exhibited superior lubrication and cooling characteristics, yielding the lowest cutting force, temperature, and surface roughness ...

Multidimensional Quadrilateral Lattices are Integrable

open access: yes, 1996
The notion of multidimensional quadrilateral lattice is introduced. It is shown that such a lattice is characterized by a system of integrable discrete nonlinear equations. Different useful formulations of the system are given. The geometric construction

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

Modulating Electronic Properties of N‐Heterocyclic Carbene Ligands: Effects on the Pd‐Catalyzed Buchwald–Hartwig Amination

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 2, January 12, 2026.
Pd complexes with electronically modified NHCs (NHC = N‐heterocyclic carbene) were analyzed in the Buchwald–Hartwig Amination under both strongly and weakly basic conditions. Investigations into the steric and electronic properties of the ligands are detailed.
