In Vitro Evaluation of Apricot Cultivars Response to Pseudomonas syringae Pathovars: Image Processing as an Alternative Method

Türkiye, with an apricot (Prunus armeniaca L.) production amount of 833,398 tons per year, ranks first in fresh apricot production and dried apricot export in the world. Malatya, Iğdır, and Elazığ constitute the main apricot production centers in Turkey. Many table and dried apricot cultivars have been grown in Türkiye. Local apricot cultivars such as cv. Şalak (or Aprikoz), cv. Tebereze, cv. Ordubat, cv. Ağcanabat, and cv. Ağerik are widely grown in the Aras Valley, including Iğdır and Kağızman. In this study, DNA barcoding of local cultivars based on the ITS region was performed and their distribution demonstrated in the Aras Valley. The reactions of these apricot cultivars to the causal agents of bacterial canker, which negatively affect the yield and quality of apricot cultivation, were also determined. Alternative methods such as image-processing technology and CHAID analysis have also been successfully used for cultivar reaction tests. It was determined that "Şalak" is economically important and the most common apricot cultivar in the Aras Valley. In addition, the Ağcanabat cultivar was sensitive to the causal agents of disease, while other local apricot cultivars were tolerant to it

Topology Optimization of Masonry Structures

Designing structures that are more sustainable is a relevant topic within the construction industry. By choosing materials that have a low embodied energy value and optimizing the structures that can be constructed by these materials, one could potentially minimize the economical and environmental footprint of a structural design.As burnt clay bricks have a relatively low embodied energy value, are relatively cheap as a construction material and are relatively durable, it is interesting to investigate the optimization of masonry structures. To achieve this, use is made of topology optimization. To accurately optimize the topology of masonry structures however, this optimization must be performed based on the results of a discrete element analysis. This thesis presents several methods to set up such a model based on masonry structures of arbitrary size and lay-out, departing from the smallest scale: the individual brick.First, a method is developed to create arbitrary shapes for bricks. An algorithm is developed to parametrically create structures for two distinct shapes. A procedure to abstract these structures and translate their geometrical representation to a simplified numerical model is then presented. Severalmethods for structural analyses are detailed and their results are evaluated and compared. The results of these analyses are used to optimize the topology of the initial structure by means of the Method of Moving Asymptotes. The resulting structures are then verified using 3DEC. Finally, some applications of the developed method are presented along with future visions.Double degree in Civil Engineering | Structural Engineering and Architecture, Urbanism and Building Sciences | Building Technology This thesis is written to obtain a Master's degree from both Building Technology (BT) at the faculty of Architecture and the Built Environment, and Structural engineering (SE) at the faculty of Civil Engineering and Geosciences. Files that are specifically intended for one of the study programmes are prefixed by either BT or SE. The same report and presentation are written for both programmes. In the thesis report (section 1.4), it is noted which parts of the report are relevant for which study programme.Civil Engineering | Structural Engineering / Architecture, Urbanism and Building Sciences | Building Technolog

A rare epididymal mass: Leiomyoma

Leiomyoma is a benign smooth muscle tumor. It rarely rises from epididymal structures and usually is encountred in adults. The patient, who had undergone total epididymectomy for right scrotal mass at another center, was diagnosed with Epididymal Leiomyoma. He was admitted to our clinic for further evaluation and follow up. The previous eididymectomy specimens obtained and refered to our pathology department for confirmation of diagnosis. Microscopy revealed a benign neoplastic lesion, consisting of spindle cells. Which form interlacing bundels.Mitotic figures and tumor necrosis was not. Observed. The previous diagnosis is confirmed as the tumor showed immunohistochemical smooth muscule actin and Desmin posivity Whereas S-100 was not expressed with in the tumoral cells. This case report also overviews epididymal leiomyoma with recent literature findings. [Cukurova Med J 2014; 39(2.000): 399-402

Methodology the centres participating in the study were divided into three groups as tertiary referral centres, state hospitals and private practice hospitals. the number of outpatients, inpatients, daily interventions and urological surgeries were recorded prospectively between 9-March-2020 and 31-May-2020. All these variables were recorded for the same time interval of 2019 as well. the weekly change of the workload of urology during pandemic period was evaluated, also the workload of urology and the distributions of certain urological surgeries were compared between the pandemic period and the same time interval of the year 2019. Results A total of 51 centres participated in the study. the number of outpatients, inpatients, urological surgeries and daily interventions were found to be dramatically decreased by the 3rd week of pandemics in state hospitals and tertiary referral centres; however, the daily urological practice were similar in private practice hospitals throughout the pandemic period. When the workload of urology in pandemic period and the same time interval of the year 2019 were compared, a huge decrease was observed in all variables during pandemic period. However, temporary measures like ureteral stenting, nephrostomy placement and percutaneous cystostomy have been found to increase during Covid-19 pandemic compared with normal life. Conclusions Covid-19 pandemic significantly affected the routine daily urological practice likewise other subspecialties and priority was given to emergent and non-deferrable surgeries by urologists in concordance with published clinical guidelines
