This study combines palynological, ecological, and molecular techniques to elucidate the taxonomic relationships within the complex genus Centaurea. By analysing quantitative parameters such as P, E, P/E ratio, colpus length, exine thickness, and ornamentation from SEM studies, we investigated pollen morphology across five species—C. behen, C. regia, C. iberica, C. virgata, and C. solstitialis—collected along a climatic gradient in Iraq, Iran, and Turkey. The findings indicate significant ecotypic variation strongly associated with local environmental conditions. Iranian populations, adapted to dry conditions, exhibit thicker exines and longer colpi, suggesting enhanced desiccation resistance. Turkish populations tend to have thinner exines and longer grains, likely optimised for temperate pollination environments. Iraqi populations show intermediate pollen traits, reflecting their role as transitional ecotypes in semi-arid regions. These results highlight how environmental adaptation shapes reproductive morphology and offer a basis for integrative taxonomy, leveraging adaptive traits to refine species delimitation and clarify phylogenetic relationships within Centaurea.
O’Malley and Chamot (1990) define learning strategies as “the special thoughts or behaviors that individuals use to help them comprehend, learn or retain new information†(p. 1). In recent decades, many Iranian scholars have concentrated on learning strategies as an effective way for acquiring knowledge. This paper aims to have a profound, comparative look at the start, development and the current position of EFL learning strategy field of study in Iran.

Abstract. Iraq is characterized by a distinctive botanical and geological diversity with different plant families, monocotyledons and dicotyledons, the spread of dicotyledonous plants was more unique and of other species, For example, in Al-Tib, Maysan, Iraq, which through field trips to study the plant diversity and the surrounding conditions at these areas, it was found that the species belong for many plant families, dicotyledonous and monocotyledonous plants, including: Amaranthaceae, Apiaceae, Asteraceae, Boraginaceae, Brassicaceae, Capparidaceae, Caprifoliaceae, Caryophyllaceae, Convolvulaceae, Euphorbiaceae, Fabaceae, Geraniaceae, Lamiaceae, Malvaceae, Papaveraceae, Plantaginaceae, Primulaceae, Salicaceae, Ranunculaceae, Solanaceae,

All experiments conducted in this field were based on the following nanoparticles: gold nanoparticles, silver nanoparticles, zinc nanoparticles, and sodium chloride nanoparticles. Most of these experiments were reviewed in terms of differences in the concentrations of nanoparticles and the method that was used in the experiments whether it was in vivo or in vitro. These particles used in most experiments succeeded in inhibiting the growth of Leishmania parasites.
Reservoir characterization is an important component of hydrocarbon exploration and production, which requires the integration of different disciplines for accurate subsurface modeling. This comprehensive research paper delves into the complex interplay of rock materials, rock formation techniques, and geological modeling techniques for improving reservoir quality. The research plays an important role dominated by petrophysical factors such as porosity, shale volume, water content, and permeability—as important indicators of reservoir properties, fluid behavior, and hydrocarbon potential. It examines various rock cataloging techniques, focusing on rock aggregation techniques and self-organizing maps (SOMs) to identify specific and

In order to study the malacological diversity of this site, a survey of the marsh molluscs species was made during this study. About 177 specimens were collected, seven species of gastropods belonging to six families and two species of Bivalves belonging to one family were identified, remarks on the nomenclature, taxonomy and distribution of these species. According to this study Al-Dalmaj Marsh includes diverse molluscs species and the presented results will provide important information for future studies concerned with the molluscs or Invertebrates
