This study investigates the effects of an AI-supported irrigation system on the production of natural plant species and irrigation efficiency at Rize Recep Tayyip Erdoğan University. To enhance water resource efficiency while utilizing Turkey’s rich plant diversity, Geranium psilostemon Ledeb. (Black-Eyed Crane’s-Bill) was selected for cultivation. The research includes adaptation trials and growth monitoring of this perennial taxon, which naturally grows at an altitude of 2000 m. The experiments were conducted in two different environments: one utilizing an AI-supported irrigation system and the other relying on manual irrigation. The findings reveal that AI-supported irrigation systems optimize irrigation strategies, providing a more efficient and effective plant cultivation process compared to manual irrigation. The AI-supported irrigation system continuously monitors air and soil moisture levels, ensuring optimal irrigation conditions and instant adaptation to seasonal variations. This innovative approach minimizes water losses while preventing soil salinization, thereby offering a significant solution for sustainable agricultural practices. In conclusion, this study demonstrates that natural plant species can be effectively cultivated using AI-supported irrigation systems and that these systems hold great potential for water conservation and ecological balance. These findings present a crucial step toward developing effective solutions for global water challenges and promoting sustainable landscape and agricultural practices.

In this article, a 3-D printed microwave (MW) probe is proposed to operate within 2.4–2.5-GHz industrial, scientific, and medical (ISM) band along with the numerical and experimental results for the local annihilation of contained tumor tissue that is the type of a human breast cancer cell line (MCF7) in MW ablation systems. The proposed MW ablation probe is fabricated by using an acrylonitrile butadiene styrene (ABS) material to construct a lightweight, cost effective, and easy to fabricate an MW applicator. The design principle of 3-D printed MW probe is based on the structural formation of coaxial transmission-line fed dielectric-loaded cone-shaped radiator for the near-field energy concentration in the close proximity of the cancerous tissue to be ablated at 2.45 GHz. Since conductive coating techniques have been improved recently, the inner surfaces of the designed MW applicator have been coated with the copper spray conveniently for the final fabricated probe prototype. The designed MW applicator has been numerically studied in CST MW Studio in an attempt to develop the near-field radiation performance, which can affect the ablation performance of MCF7 cells. The computation and experimental measurement results agree quite well with the indication of 3-D printed MW ablation probe to be utilized as an alternative medical device for cancer treatment.

Son dönemlerde artan yapılaşmalar, çevre kirlilikleri vb. çevre sorunlarının artmasıyla kentlerin termal konforu olumsuz etkilenmektedir. Rize kenti için önemli bir yere sahip olan Recep Tayyip Erdoğan Üniversitesi (RTEÜ ) Zihni Derin yerleşkesinde farklı özelliklere sahip alanlar, farklı yapı malzemeleri ve bitki dokuları termal kamera ile görüntülenmiştir. 2023 yılı ağustos ayı içerisinde aynı bakı, yükseklik ve yakın fiziksel özelliklere sahip (yeşil alan, gölgelendirme ve malzeme tipi) alanlardan seçilen mekânların yüzey sıcaklık değişimleri, 10 farklı alanda termal kamera kayıtlarının görüntü işleme metotları ile analiz edilmesiyle ortaya koyulmuştur. Aynı gün içerisinde 15:00-16:00 saatleri içerisinde yapılan ölçümler sonucu yeşil alan, sert zeminler ve yapı malzemeleri arsındaki yüzey sıcaklık farkları tespit edilmiştir. Bu veriler doğrultusunda ölçümü yapılan bölgelerin termal konfor bakımından ideal aralıkta olma durumları tespit edilmiştir. Bu değerlendirmeler sonucunda kentsel alanlardaki termal konfor açısından bitkilerin önemli olduğu, yapılan tasarımlarda bitkisel alanların, ahşap zeminlerin ve gölgelendirmelerin arttırılması gerektiği görülmüştür. Bu çalışmanın benzer çalışmalar için öncü olması düşünülmektedir.

In this paper, a radiation performance improved novel applicator is proposed which is called as reflector type microwave applicator as a part of microwave ablation (MWA) system operating at 2.45 GHz with experimentally measured bandwidth of 300 MHz in Industrial Scientific Medical (ISM) band for the local extermination of tumor with highly localized microwave power. The design principle of MW applicator is based on the structural formation of coaxial transmission line fed dielectric loaded with the metallic circular reflector for the near field energy concentration inside the tumorous tissue. To generate localized electromagnetic waves, a novel reflector type microwave applicator is designed by placing an aluminum disk near the 10 mm dielectric radiator section. The proposed applicator design has been numerically studied with finite integration technique (FIT) in CST Microwave Studio to develop the near field radiation pattern affecting the ablation level of tumorous tissue. In the light of performed numerical calculations, maximum SAR (Specific Absorption Rate) value on 1.76 g tumorous sample can be achieved to 208 W/kg under 15 W microwave power accepted by proposed probe. The experimental results confirm that proposed applicator can be utilized highly localized MWA applicator for cancer treatment hence the surface temperature of cylindrical shaped tumor sample which has the dimensions of 14.4 mm diameter and 8 mm height reaches from 25 to 68.3°C in 10 min.
