Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…
The metal ions accelerate drug action and efficiency of therapeutic compounds [1]. Metal complexes may inhibit the protein synthesis because of interference in the cellular respiration. Cancer is leading cause of fatality in recent years and remained as a ch…
Gelişen teknoloji ve artan nüfusun etkisiyle enerji tüketimi giderek artmaktadır ve bu durum tüm dünyada olduğu gibi ülkemizde de önemli bir problem olarak karşımıza çıkmaktadır. Fosil enerji kaynakları gün geçtikçe azalmaktadır ve bu nedenle araştırmacılar …
Cherry trees do not reproduce from seed. Desirable cultivars are grafted onto rootstocks which is generally clonally propagated. Many cherry rootstocks have been released around the world and a wide range of cherry rootstocks is available for growers. The cu…
Radyo ve Televizyon Üst Kurulu’nun derlediği verilere göre 2017 yılında Türk insanı, günlük 5 saat 30 dakika televizyon izleyerek dünyada birincidir. Türkiye’de ürünlerin tanıtımı ve marka bağlılığı yaratmanın en kolay ve hızlı yollarından biri, televizyon p…
Forest workers generally work under severe conditions. Wood work; far from social spaces, weather conditions and rugged terrain. There is also no room for errors that are connected to a plan. Accident risk is high in forest workers. Accident risk must be hig…
Optimal operation of the power systems is very important. In this paper, a new approach for both the economic active power flow and active power loss minimization in multi-terminal HVDC systems is proposed. In the proposed optimization approach, system constra…
Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…
The reuse of wastewater reduces both the consumption of freshwater resources and minimizes the environmental impact of discharged wastewater. Biological treatment technologies have been utilized in wastewater reclamation for over a century. Membrane Bioreactor…
Low energy and water consumption of green buildings during the life cycle, waste management, minimizing the impact of projects on the ecosystem and increasing the use of environmentally friendly materials have made high performance green buildings attractive…
We are at a time when electronic systems are structured in a manner similar to the human brain.The memristor, a neuromorphic circuit designed by Chua in 1971, is a modeling of synaptic learning and associative learning. Neuromorphic circuit elements and memris…
Bitumen polymer modification has a long history. However, most of the polymers currently used as additive in bitumen are not economically attractive. Thus, employing recycled materials in flexible highway instead of virgin ones has become a fundamental case …
Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding …
To follow the class attendance of the students is a challenging and time consuming process in terms of lecturer. Followup of class attendance at universities is done by circulating the attendance sheet in class. The number and signature of each student is got.…
When the traditional fuel reserves are limited and the environmental factors of these fuels are taken into consideration, the importance of renewable energy sources is increasing day by day. Especially, obtaining electricity from solar energy has become popula…
