A case study on fault detection in power transformers using dissolved gas analysis and electrical test methods

This paper presents methodologies for power transformer fault diagnosis using dissolved gas analysis and electrical test methods. These methods are widely used in determination of inception faults of power transformers. Dissolved gas analysis test provides fault diagnosis of power transformers. On the other hand the electrical test methods are used for detection of root causes and fault locations and they provide more specific information about the faults. The aim of this work is to study the faults that are measured and recorded in Turkish Electricity Transmission Company (TEIAS) power systems. For this purpose, four specific cases are considered and analyzed with dissolved gas analysis and electrical testing methods. Three of these cases are defective situations and one case is a non-defective situation. These real cases of measurements have been analyzed with both methods in detail. Assessment results showed that a single method cannot yield accurate enough results in some specific fault conditions. Therefore it was concluded that cooperation of both methods in the assessment of fault condition gives more trustworthy results. © JES 2016 on-line : journal/esrgroups.org/jes

Çalışma Macrophomina phaseolina'nın çilekte neden olduğu solgunluk ve kuruma sorunları üzerine bazı organik madde uygulamalarının etkisini incelemek amacıyla yürütülmüştür. Bu amaçla toprağa zeytin karasuyu, tavuk gübresi, kükürt, pamuk delintasyon atığı, vermikompost; bitki artığı olarak soğan, pırasa, karnabahar, brokoli, lahana, buğday, bakla, marul, hardal bitkileri karıştırılmıştır. Çalışmada çilekten izole edilmiş virulensi yüksek M. phaseolina izolatı (Omp1) toprağa 50 ms/g olacak şekilde bulaştırılmıştır. Uygulamaların M. phaseolina mikrosklerotları üzerine etkisini saptamak için ise organik madde karıştırılmış steril ve steril olmayan toprağa inokulum bulaştırılmış ve 30 gün inkube edildikten sonra mikrosklerot izolasyonu yapılmıştır. Bitkiler söküldükten sonra saksı toprağındaki mikrosklerot canlılığına organik maddelerin etkililiğini saptamak için topraktan mikrosklerot izolasyonu yapılmıştır. En düşük mikrosklerot sayısı kükürt (100 gr/da) uygulamasında 8,8 mikrosklerot / 1 gr toprak olarak saptanmıştır. Steril toprak koşullarında en düşük 1 gr topraktaki mikrosklerot sayısı ise sırasıyla zeytin karasuyu (0,8), brokoli (2,5), vermikompost (6,0) ve hardal (6,7) olarak saptanmıştır. M. phaseolina bulaştırılmamış saksı topraklarında en iyi bitki gelişimi tavuk gübresi, kükürt (100 kg/ da) ve kükürt (50 kg/da), M. phaseolina bulaştırılmış saksı topraklarında ise kükürt (50 kg/da), kükürt (100 kg/ da) uygulamalarında olmuştur. This study were conducted to assess the effectiveness of some organic amendments on Macrophomina phaseolina that cause collapsed and dying problems on strawberry plants. For this purpose, olive oil waste, poultry manure, sulphur, cotton delintation waste, vermicompost; as a plant material onion, leek, cauliflower, broccoli, cabbage, corn, wheat, broad bean, lettuce, mustard were incorporated in soil. In this study, high virulent M. phaseolina (Omp 1), isolated from strawberry plant were inoculated at a rate of 50 ms/g soil. In order to determine the effects on microsclerotia of M. phaseolina, organic amendment incorporated sterile and non-sterile soil was infested with M. phaseolina inoculum and microsclerotia isolation were done after incubated for 30 day. In pot studies, the plants growing in the soil which was infested M. phaseolina, were evaluated in terms of disease severity during the trial and at the end of the trials plants uprooted and recorded their weights to determine the effects on plant growth. After uprooting strawberry plants from pots, to determine the effects of organic amendments on microsclerotia viability in pot soil, microsclerotia were isolated from the pot soil. The lowest microsclerotia were detected sulphur (100 gr/da) added soil at 8,8 microsclerotia/1 gr soil. In sterile soil, lowest microsclerotia were detected respectively incorporated with olive oil waste (0,8), broccoli (2,5), vermicompost (6) and mustard (6,7). In pot trials without M. phaseolina, poultry manure, sulphur (100 kg/da) and sulphur (50 kg/da) gave the best results according the plant growth rate. In pot trials inoculated with M. phaseolina best plant growth rate were obtained respectively, sulphur (50 kg/ da), sulphur (100 kg/da)

Enhancing EFL Learners’ Free Writing Skill with a Web 2.0 Tool ‘Storybird’; an Action Research

Freewriting is perceived as a pre-writing activity to collect language learners' initial ideas before the actual writing process. Unlike brainstorming activities, language learners should write their ideas and thoughts without concerning grammatical rules, spelling, punctuation or coherence, etc. throughout the given time. Freewriting activity prepares the student for an actual writing activity and enables them to produce more comprehensible and eligible texts. Current research aims to investigate whether free writing activity can be digitalized through a handy tool, which is Storybird, in preparatory classrooms. The research was carried out with 54 EFL learners in the 2019 fall term of the academic year. The participants were English language teacher candidates who have studied English for many years in Turkey. The research was designed as action research and qualitative finding were gathered. The treatment process lasted for four weeks and a written structured interview was administered at the end of the treatment process. Results of the current study show that nearly all the participants are satisfied with the utilization of Storybird in free writing activities. Additionally, they thought that the tool boosts their attitudes toward writing. The results indicate that free writing activities can be carried out digitally to make language learners more engaged and productive in writing

The importance of community-based natural resource management in the development of nature-based tourism activities

Doğaya dayalı turizm faaliyetlerinin gelişimi hiç kuşkusuz doğal kaynakların korunması ile yakından ilişkilidir. Doğal kaynakların korunması ise toplumlar tarafından ciddiye alınması gereken önemli bir konudur. Bu durum ise toplum temelli doğal kaynak yönetimini (TTDKY) ön plana çıkarmaktadır. TTDKY son yıllarda biyolojik korunmanın sürdürülebilirliğinin gerçekleşmesi ve sosyo-ekonomik hedeflerin sağlanması amacıyla toplumlar tarafından yaygın olarak teşvik edilmektedir. TTDKY; doğal kaynakların korunması, sürdürülebilirliğinin sağlanması ve gelecek nesillere bırakılması amacıyla gerekli olan tüm sorumluluğun sadece belirli ya da görevli bir kesim tarafından değil toplumun her kesimi tarafından paylaşılmasını içermektedir. Bu çalışmada doğaya dayalı turizm faaliyetlerinin gelişiminde TTDKY’nin öneminin vurgulanması amaçlanmaktadır.Undoubtedly, development of nature-based tourism activities is closely related to the conservation of natural resources.
