Botan Vadisi Milli Parkı
No full textBotan Çayı Vadisi ve Milli Parkı, Siirt ve çevresinde, Güneydoğu Anadolu Bölgesi’nin plato alanı ile Güneydoğu Toroslar arasında, Siirt şehrinin doğusunda yer alan jeolojik ve jeomorfolojik açıdan zengin bir sahadır. Vadi ve çevresi, Jura tipi kıvrımlı yapılar üzerinde kurulmuş olup, Garzan, Sadak ve Kavika antiklinalleri ile senklinaller yörenin topografyasını şekillendirmiştir. Botan Çayı, Kezer ve Reşan çayları, derin vadiler yararak plato yüzeyi ile vadi tabanı arasında yaklaşık 500 metrelik yükselti farkı oluşturmuştur. Bu akarsular, tektonik hareketlerin etkisiyle kafesli drenaj ağına sahip kıvrımlı ve kırıklı bir arazi yapısı sergiler.
Bölgenin jeolojik yapısı Üst Kretase’den günümüze uzanan çeşitli formasyonlardan oluşur. Garzan Formasyonu (Üst Kretase), karstik yapılar ve yer altı çökmeleriyle dikkat çekerken, Germav Formasyonu (Üst Kretase-Paleosen) gri marn serisiyle tanınır. Gercüş Formasyonu (Paleosen-Alt Eosen), kırmızı marn ve konglomera tabakalarıyla erozyona duyarlıdır. Hoya (Midyat) Formasyonu (Orta Eosen) ise plato yüzeylerini örten, erozyona dirençli kalkerleriyle öne çıkar. Tektonik açıdan aktif bir konumda bulunan yöre, Arap platformu ile Anadolu levhasının temas hattında yer alır ve kuzey-güney yönlü sıkışmalar sonucu kıvrımlar, faylar ve bindirmeler oluşmuştur.
Jeomorfolojik olarak, Botan Vadisi tektonik hareketler ve akarsu aşındırmalarının etkileşimiyle şekillenmiştir. Botan Çayı, Kavika ve Gökçedağ antiklinallerini yararak derin kanyon vadiler ve gömük menderesler oluşturmuştur. Bu vadiler, erozyon, heyelan ve taş düşmesi gibi kütle hareketlerine duyarlıdır. Bölgedeki barajlar (Alkumru, Kirazlık ve Ilısu), vadi ekosistemini ve jeomorfolojik dengeyi etkileyen, ayanı zamanda vadiye yeni peyzaj görünümü kazandıran beşeri unsurlardır.
İklimsel olarak, Siirt’in yıllık yağış ortalaması 735,2 mm, ortalama sıcaklığı 16,1°C’dir. Botan Çayı’nın akımı ilkbahar aylarında (nisan-mayıs) pik yapar ve yıllık ortalama 133,453 m³/sn’dir. Flora ve fauna açısından zengin olan vadi, meşe ormanları, Akdeniz ve İran-Turan fitocoğrafya bölgelerine ait bitki türleri ile kurbağa, sürüngen, kuş ve memeli türlerini barındırır.
15 Ağustos 2023’te Resmi Gazete’de yayımlanan kararla “Botan Vadisi Milli Parkı” ilan edilen saha, 120 bin dönümlük alanı ve 29 kilometrelik güzergahıyla Siirt merkez, Tillo ve Eruh ilçelerini kapsar. Tarihi İpek Yolu’nun bir kısmı, kiliseler, manastırlar ve Rasıl Hacar Tepesi gibi doğal güzellikleriyle ziyaretçilerin ilgisini çeken Milli park çevresinin, tektonik ve kütle hareketleri, erozyon ve barajların çevresel etkileri gibi riskleri barındıran, korunması gereken hassas bir çevre olduğu unutulmamalıdır
Synthesis And Characterization Of Polystyrene/layered Hydroxide Salt Nanocomposites [síntese E Caracterização De Nanocompósitos De Poliestireno/hidroxissal Lamelar]
No full textPolystyrene/layered hydroxide salt (LHS) modified with sodium dodecyl sulfate was synthesized by in situ polymerization. The materials synthesized were characterized by gravimetry, X-ray diffraction (XRD), thermogravimetry analyses (TGA), differential scanning calorimetry (DSC) and the flammability test (FT). XRD demonstrated that synthesized nanocomposites in all compositions studied showed poor global dispersion of LHS in polystyrene. TGA showed a slight decrease in thermal stability. DSC curves showed that the glass transition temperature of polystyrene and nanocomposites were similar. The FT showed that the nanocomposite with low load of LHS exhibited good results.3711821Botan, R., Nogueira, T.R., Lona, L.M.F., Wypych, F., (2011) Polímeros, 21, p. 34Souza, M.A., Pessan, L.A., Rodolfo, Jr.A., (2006) Polímeros, 16, p. 257Nogueira, T., Botan, R., Wypych, F., Lona, L., (2011) Composites Part A, 42, p. 1025Camargo, P.H.C., Satyanarayana, K.G., Wypych, F., (2009) Mater.

Candidate perceptions of the UK Recorded Consultation Assessment: cross-sectional data linkage study
No full textThe Recorded Consultation Assessment (RCA) was rapidly developed to replace the Clinical Skills Assessment (CSA) for UK general practice licencing during COVID-19. We aimed to evaluate candidate perceptions of the RCA and relationships with performance. We conducted a cross-sectional survey of RCA candidates with attitudinal, demographic, and free text response options, undertaking descriptive and factor analysis of quantitative data with qualitative thematic analysis of free text. Binomial regression was used to estimate associations between RCA pass, candidate characteristics and questionnaire responses.
645 of 1551 (41.6%) candidates completed a questionnaire; 364 (56.4%) responders permitted linkage with performance and demographic data. Responders and non-responders were similar in exam performance, gender and declared disability but were significantly more likely to be UK graduates (UKG) or white compared with international medical (IMG) or ethnic minority graduates. Responders were positive about the digital platform and support resources. A small overall majority regarded the RCA as a fair assessment; a larger majority reported difficulty collecting, selecting, and submitting cases or felt rushed during recording.
Logistic regression showed that ethnicity (white vs minority ethnic: odds ratio [OR] 2.99,95% confidence interval [CI] 1.23, 7.30, p = 0.016), training (UK vs IMG: OR 6.88, 95% CI 2.79, 16.95, p < 0.001), and English as first language (OR 5.11, 0% CI 2.08, 12.56, p < 0.001) were associated with exam success but questionnaire subscales, consultation type submitted, or extent of trainer review were not. The RCA was broadly acceptable but experiences were variable. Candidates experienced challenges and suggested areas for improvement

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
