    (Bursa Uludağ Üniversitesi, 2021-11-25) Arslan, Aslı Ayhan; Biçen, Tuğba; Vardar, Ali; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Fen Bilimleri Enstitüsü/Biyosistem Mühendisliği Bölümü.; 0000-0001-6349-9687; 0000-0003-0018-0825; 0000-0001-6826-2494
    In this study, the objective was to find at what rate Bursa province of Turkey, is affected by the climatic process called "climate change" and the impacts of climate change on the potential of renewable energy resources, especially solar energy and wind energy. As a result of analyzes, it is seen that there is significant warming between 1960 and 2017. Especially soil temperatures and solar radiation intensity support this result. As a result of this work, it was determined that the changes in climate parameters for the province of Bursa have significant effects on renewable energy potential. According to the results obtained, there has been an increase of 34.5% in the solar energy potential, of 8.2% in thermal solar energy potential and of 3.6%-6.7 in soil temperature potential depending on the depths. In the wind energy potential, there was a decrease of 75% between 1960-1998 and an increase of 217.1% between 1999-2017.

    The design process of children's playgrounds connecting indoor and outdoor spaces: Case of Bornova children's world, Izmir
    (Bursa Uludağ Üniversitesi, 2020-12-14) Demir, Sara; Turan, Okan; Günay, Emre
    The spatial planning and design process are based on the user profiles and their needs. In this context, it is important to know the characteristics of the user groups consisting of children, young people, the elderly and individuals with special needs in terms of healthy and successful design. Therefore, in the design for child users, indoor and outdoor spaces serving the physical, cognitive, and socio-sensory development and based on the principles of colorfulness, mobility and naturalness should be designed. The Children’s World project designed in this context was realized in Bornova district of İzmir province in Turkey. The aim of this study is to design indoor and outdoor playgrounds that reflect the world of children. The children’s playgrounds aim to serve the developmental stages of the child and to be based on the landscape design principles in playgrounds. The landscape design process was implemented step by step for healthy children’s playgrounds. The physical, cognitive, and socio-sensory developmental stages of the children and the colorfulness, mobility and naturalness design criteria of the children’s playgrounds with the flooring materials with playful and colorful patterns, the movable cube game modules and seating units and the plant material that changes color in all seasons were handled within the framework of a holistic design and accordingly, portable and colorful indoor and outdoor playgrounds consisting of exhibition-information-experience areas, workshops and courtyards were created. As a result, in this study which includes original, qualified, functional, innovative and contemporary design solutions, settlement decisions, plan decisions, facade and material decisions, sustainability decisions, and open space decisions were taken. The findings and methodology of this study may serve as an example of the landscape design process for other similar projects to be designed in different regions that take into account the developmental periods and principles of children.

    Responses of Spinacia oleracea L. cv. matador plants to various abiotic stresses such as cadmium metal toxicity, drought and salinity
    (Bursa Uludağ Üniversitesi, 2020-12-25) Akpınar, Ayşegül; Cansev, Asuman; Acun, Deniz Zahide Altınşeker; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü Bölümü.; 0000-0002-3353-846X; 0000-0002-9716-3900
    Spinacia oleracea L. cv. Matador plants produced in many regions are exposed to many abiotic stresses from drought to metal toxicity. In this study, the effects of drought (control: 100% field capacity (FC), D1: 50% FC and D2: no-watering), salinity (100 and 200 mM NaCl) and cadmium (Cd; 100 and 200 µM CdCl2) metal toxicity, which are among the most common abiotic stress factors, on spinach plants were determined at the cellular level. There was not determined any alterations along 10 days’ drought, salinity and Cd stress in dry and fresh weights of spinach plants grown in plant growth chamber, in which there is a 16-hour photoperiod under a light intensity of 1200 lux at 24°C/20°C (day/night). However, all treatments caused oxidative stress. Cd treatments were more structurally damaging than drought and salinity treatments. In drought and salinity treatments, chlorophyll content and dry weight did not change despite the increased superoxide dismutase (SOD) and catalase (CAT) activities. The highest values in SOD activity were obtained at D2-drought treatment and 200 mM salinity treatment. SOD activity determined in Cd treatments was also increased compared to control, but this increase was lower than the other treatments. Thus, it can be considered that CAT enzyme is primarily scavenger of reactive oxygen species (ROS) in spinach plants under Cd stress. As a results, spinach plants had an ability to cope with this stresses. The different responses of spinach seedlings to various stress factors provide for estimate of the plant's powerful physiological mechanism. In the continuation of this study, it is recommended to conduct molecular studies and to investigate of the cellular responses to long-term stress on Spinacia oleracea L. cv. Matador plants, which we found to be tolerant to short-term stresses.
