Journal of Chemistry, Volume 2026, Issue 1, 2026.Environmental contamination by trace and heavy metals (THMs), driven by anthropogenic activities like industry, mining, and agriculture, poses a persistent global public health threat. These nondegradable contaminants lead to widespread human exposure via ingestion, inhalation, and dermal contact, causing diverse adverse health outcomes, including ...

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.ABSTRACT Pistacia species are widely used in traditional medicine, particularly for wound healing. This study investigated the fatty acid composition of fruits from four Pistacia species collected from various regions of Algeria. Dried fruits of Pistacia lentiscus L. were extracted using hexane in a Soxhlet apparatus.

Heat Transfer, Volume 54, Issue 5, Page 3193-3207, July 2025.ABSTRACT High‐pressure turbine blade tips operate under extreme thermal stress, generating significant aerodynamic losses that must be continually optimized to improve engine efficiency and durability. This study uses computational fluid dynamics (CFD) to investigate the aerodynamic and thermal behavior of advanced turbine blade tip configurations ...

REFINEMENTS OF SOME RETARDED INTEGRAL INEQUALITIES OF GRONWALL-BELLMAN-BIHARI TYPE AND THEIR APPLICATIONS [PDF]
Surveys in Mathematics and its Applications, 2020 In this study, some generalizations and refinements of some retarded integral inequalities of Gronwall-Bellman-Bihari type are established. To show the feasibility of the obtained inequalities, some illustrative examples are also introduced.

Microcylinder and Slot Combination for Flow Separation Control Over a Wind Turbine Airfoil
Wind Energy, Volume 28, Issue 7, July 2025.ABSTRACT This study explores a novel passive flow control strategy combining a microcylinder and slot configuration to mitigate flow separation over an S809 wind turbine airfoil under stall conditions at a Reynolds number of 106. Numerical simulations are conducted using the Reynolds‐averaged Navier–Stokes (RANS) approach. The primary objectives are to

Hydrochemical study of Drean–Annaba aquifer system (NE Algeria)
Journal of Water and Land Development, 2017 Abstract Water quality is subject to frequent changes in the Drean-Annaba alluvium aquifer. Water-rock interaction can not be the only process that produces the observed modification, but dryness that the country knew during the last two decades has highly contributed to the water quality changes.
