- Planning sustainable green blue infrastructure in colombo to optimize park cool Island intensityPublication . Wijesundara, A. A. S. G.; Sewwandi, B. G. N.; Panagopoulos, ThomasColombo, a rapidly urbanizing city, increasingly faces the Urban Heat Island (UHI) effect due to urban expansion and climate change. Urban parks mitigate UHI by creating cool microclimates, quantified as Park Cool Island Intensity (PCII), the temperature difference between parks and surrounding areas. Colombo exhibits an average cooling effect of 0.98 ◦C } 0.21%. The results found that the park area has the most significant positive relationship with the PCII, where the model explained 87.7% of the variance (R2 = 0.877), indicating a strong fit, following the park perimeter (R2 = 0.811). Park vegetation characteristics exert a significant influence to enhance the cooling effect, with canopy density emerging as a primary factor with a variance of 87.1% (R2 = 0.871). Notably, canopy density of more than 80% demonstrates a marked PCII exceeding 1.0 ◦C. Additionally, other vegetation attributes, tree basal area (R2 = 0.868), tree height (R2 = 0.784), DBH (R2 = 0.757), and stem density (R2 = 0.717), exhibit a significant positive correlation with PCII, following canopy density in descending order. Furthermore, park composition analysis reveals that higher water and green cover contribute to maximizing PCII, underscoring the importance of reducing impervious cover in urban park design. These findings provide valuable insights for urban planners in facilitating the development of more effective urban park designs aimed at maximizing cooling effects, promoting sustainable urban development, and contributing to the achievement of SDG 11 and SDG 13.
- Phytochemicals and bioactivities of the halophyte sea mayweed (Tripleurospermum maritimum L.)Publication . Lemoine, Clément; Rodrigues, Maria João; Dauvergne, Xavier; Cérantola, Stéphane; Custódio, Luísa; Magné, ChristianSea mayweed (Tripleurospermum maritimum L. syn. Matricaria maritima) is a halophytic species widely distributed along the Atlantic shoreline. Unlike other Tripleurospermum species, the chemical composition and biological activities of this halophyte have received no attention. Here, a hydroalcoholic extract of sea mayweed leaves was evaluated for in vitro antioxidant (DPPH, ABTS, and FRAP bioassays), anti-inflammatory (NO reduction in RAW 264.7 macrophages), anti-diabetic (alpha-glucosidase inhibition), neuroprotective (inhibition of acetylcholinesterase), and skin protective (tyrosinase, melanogenesis, elastase, and collagenase inhibition) activities. Solid–liquid partition chromatography of the extract and NMR characterization of its fractions allowed the identification of some major compounds, including fructo-oligosaccharides in the MeOH20% fraction, a new carbohydrate called tripleurospermine (1), 3-5-dicaffeoylquinic acid (2) in the MeOH40% fraction, and matricaria lactone (3) in the MeOH80% fraction. MeOH40 fraction exhibited strong antioxidant, anti-tyrosinase (thus skin-whitening potential), and anti-glycosidase activities (anti-diabetic potential), whereas MeOH80% fraction showed anti-inflammatory and anti-diabetic potential. Overall, our results suggest that sea mayweed may have dietary or medicinal uses due to its biochemical composition and bioactivities.
- Literary tourism, collective memory, and education: cultural memory experience at the Yahya Kemal MuseumPublication . Çevik, Samet; Baleiro, Rita; Sariipek, SemihThis study explores the educational function of the Yahya Kemal Museum within the scope of literary tourism and its role in the transmission of collective memory. The primary data for the research was obtained through an in-depth interview with the museum representative and analysed using content analysis, focusing on the museum's daily operations, visitor profile, and narrative strategies. Findings indicate that the museum positions Yahya Kemal not merely as a poet but as a symbolic figure of cultural memory and national identity, particularly through presentations, multivision screenings, and guided narrations designed for school groups, who constitute the largest segment of visitors. Personal belongings and archival materials serve to concretise an individual life story, while school collaborations, travelling presentations, and multilingual informational materials transform the museum from a static exhibition space into an active educational venue that communicates memory rather than just preserving it. Thus, the Yahya Kemal Museum is conceptualised not only as a place of display but as a literary hub that teaches, recalls, and reconstructs memory. In this respect, the study argues that literary museums should be examined not solely as nostalgic spaces but as dynamic environments of cultural learning.
