4D Printing Technology and Its Application Possibilities in Unmanned Aerial Vehicles (UAVs)

Ece Kalay | İskender Özkul

4D printing technology is an innovative manufacturing method that adds the dimension of time to traditional 3D printing, enabling materials to respond to environmental stimuli (such as temperature, humidity, light, etc.) by changing shape, properties, or functionality. This study examines the fundamental principles of 4D printing in detail and explores its advantages and potential applications in the context of Unmanned Aerial Vehicles (UAVs). The foundation of 4D printing lies in the use of smart materials such as shape-memory polymers, self-healing composites, and hydrogels. These materials allow UAV components to dynamically adapt to flight conditions through pre-programmed responses. The study also comparatively discusses 4D printing techniques (FDM, SLA, DIW, SLM) and their suitabilit...

Merkezi Elburz Dağlarının Papilionoidea ve Hesperioidea Faunası ve Taksonomisi Üzerine Araştırmalar (Lepidoptera).

HÜSEYİNOĞLU, Yusuf

Bu tez çalışması İran Merkezi Elburz Dağlarında gerçekleşmiştir. Araştırma sonucunda kelebeklere (Lepidoptera) ait 8 familya içinde 178 tür tespit edilmiştir. 133 taxon örnek toplanarak tespit edilmiştir. 47 taxon ise literatür kayıtlarına göre verilmiştir. İran faunası için Polyommatus admetus yeni bir tür olarak verilmiştir. Ayrıca birçok tür çalışma alanı için yeni kayıttır. Zoocoğrafik açıdan 46 taxa Elburz dağları için endemik olarak tespit edilmiştir. Çalışmada iran2da şimdiye kadar olan bilimsel çalışmalar kronolojik olarak verilmiştir (Lederer 1869 ile Hosseinpour 1996 yılları arasında).

Metaphoric Conceptualization of Love Pain or Suffering in Turkish Songs through Natural Phenomena and Natural Disasters

Muhammet Fatih Adıgüzel

Traditional Turkish love is identified with suffering. This study investigates how suffering in love is metaphorically conceptualized in Turkish via natural phenom ena and disasters. Based on figurative expressions in sad love songs of Arabesque and Art music genres, the study reveals that love pain/suffering is expressed through three salient metaphors: 1) LOVE PAIN/SUFFERING IS NATURAL PHENOMENA,2)LOVE PAIN/SUFFERING IS NATURAL DISASTERS, and 3) the overarching metaphor (the suffering) LOVER’SBODYISALANDSCAPE(affected by weather conditions or natural disasters). It was unearthed from metaphoric expressions in lyrics that as part of a cultural scenario, natural phenomena anddisastersareprofiledasinternalized forces culturally imagined to directly affect vital body parts to expres...
