THREE DIMENSIONAL INTERACTIVE HYDROGEOLOGICAL MODEL OF THE KEMALPASA PLAIN

Kemalpaşa Ovası, Türkiye'nin batısında İzmir ili sınırları içerisinde yer almaktadır. Her geçen gün artan su talebinin yüzeysel akiferden karşılanamaması üzerine birçok orta ve büyük ölçekli sanayi tesisi derin kuyular açtırarak derin akiferlerden su temini yoluna gitmektedir. Yapılan jeolojik etüdlerde ovada üç farklı kaya grubunun varlığı tespit edilmiştir. Çalışma alanının temelinde, Mesozoyik yaşlı Bornova Karmaşığı bulunmaktadır. Bornova Karmaşığı, allokton rekristalize kiraçtaşları, kumtaşı-şeyl, killi şistler ve fillitlerden oluşmaktadır. Konsolide olmuş Neojen tortullarını oluşturan kumtaşı, kiltaşı ve kireçtaşları uyumsuz olarak temel kayalarını örtmektedir. Kuvaterner yaşlı alüvyonel çökeller en üstte yer almaktadır. Ovada, bu üç formasyonda oluşmuş dört farklı akifer tespit edilmiştir. Bunlar, (i) Bornova karmaşığı içerisindeki Mesozoyik yaşlı allokton rekristalize kireçtaşları, (ii) Neojen birimler içerisindeki kumtaşları ve çakıltaşı tabakaları, (iii) Neojen kireçtaşları; ve, (iv) en üstte yer alan konsolide olmamış alüvyon sedimanlar olarak tanımlanabilir. Bu çalışma ile, Kemalpaşa ovasında yer alan farklı niteliklerdeki akiferlerin hidrojeolojik karakterizasyonları yapılmış ve akiferlerin üç boyutlu interaktif modeli hazırlanmıştır. The Kemalpasa Plain is located within the boundaries of the province of Izmir Province in western Turkey. The irrigational water demands of the farmers and the process water requirements of the industrial establishments are most supplied from groundwater resources of the plain. This ever-increasing demands for water could no longer be satisfied by the alluvial surfacial aquifer and, hence, numerous deep wells are being drilled in the lower aquifers to supply these high demands. Based on the geological surveys performed in the plain, three different rock formations are observed in the plain. The Mesozoic-aged Bornova Complex forms the foundation of the study area. The Bornova Complex is composed of allochthonous limestone, sandstone, clayey schist and phyllite. The consolidated Neogene sediment units overlay the basement rock by discordance. These sedimentary units are composed of sandstone, claystone and limestone. Finally, as the youngest units of the region, the Quaternary aged alluvial sediments overlay all other units. In accordance with this geological structure, four different aquifers are determined in the plain. These are classified as: (i) Mesozoic-aged allochthonous limestone in Bornova Complex, (ii) Neogene-aged sandstone and gravel, (iii) Neogene-aged limestone; and, (iv) Quaternary-aged unconsolidated alluvial sediments. In this study, hydrogeological characterization of Kemalpasa plain aquifers discussed above will be conducted and a three dimensional interactive model of these layers is prepared. Finally, a three dimensional hydrogeological model of Kemalpasa plain is prepared

The Turkish Clinical Microbiology and Infectious Diseases Society (KLİMİK) Evidence-Based Guideline for the Diagnosis and Treatment of Brucellosis, 2023

Bruselloz, dünyada ve ülkemizde çok yaygın olarak görülmesine rağmen hastalığın tanı ve tedavisini yönlendirmede kullanılabilecek kanıta dayalı bir rehber bulunmamaktadır. Bu rehber, brusellozun tanı ve tedavisi ile ilgilenen farklı uzmanlık alanlarından hekimlere kanıta dayalı öneriler sunmak üzere Türk Klinik Mikrobiyoloji ve İnfeksiyon Has- talıkları Derneği tarafından hazırlanmıştır. Rehberin hazırlanmasında, ABD İnfeksiyon Hastalıkları Derneği (IDSA)’nin Klinik Uygulama Rehberi Geliştirme Kı- lavuzu önerileri esas alınmıştır. Rehberi hazırlayan grup üyeleri tarafından, bruselloz tanı ve tedavisinde önemli olduğu düşünülen 20 soru belirlenmiş ve PICO [hasta/popülasyon (P), müdahale/indikator (I), karşılaştırma/kontrol (C), sonuç (O)] formatında oluşturulan bu sorulara yanıt verebilecek yayınlar, ULAKBİM TR Dizin, PubMed ve Cochrane veritabanlarından, tarih kısıtlaması olmadan taranmıştır. Her bir PICO sorusu ve her bir ayrı sonlanım için kanıtların derecelendirilmesinde ve önerilerin gücünün belirlenmesinde “Grading of Recommendations, Assessment, Develop- ment and Evaluation (GRADE) Working Group” yöntemi kullanılmıştır. PICO sorularına yanıt oluşturabilecek şekilde karşılaştırmalı klinik araştırmaların olması halinde bunların meta-analizleri, olmaması halindeyse olgu sunumları ve olgu serilerinden elde edilen verilerle “individual participant data” (IPD) meta-analizleri yapılmıştır. Önerilerin yeni çalışmaların sonuçları doğrultusunda belli aralıklarla güncellenmesi planlanmaktadır.Although brucellosis is very common in the world and Türkiye, there are no evidence-based guidelines to guide the diagnosis and treatment of the disease. This guide has been prepared by the Turkish Society of Clinical Microbiology and Infectious Diseases to provide evidence-based recommendations to physicians from different specialties interested in the diagnosis and treatment of brucellosis. The recommendations of the Clinical Practice Guide Development Guide of the Infectious Diseases Society of Amer- ica (IDSA) were taken as the basis for preparing this guide. The guideline preparation group determined 20 questions considered to be important in the diagnosis and treatment of brucellosis, and the publications that could answer these questions prepared in PICO (Population/Patient [P], Intervention [I], Comparison [C], Outcome [O]) format, were searched in ULAKBİM Tr Dizin, PubMed, Cochrane databases without date restrictions. The Grading of Recommen- dations, Assessment, Development, and Evaluation (GRADE) Working Group method was used to rank the evidence and determine the strength of the recommendations for each PICO question and for each individual outcome. Me- ta-analyses of comparative clinical studies were performed to answer the PICO questions. Individual participant data (IPD) meta-analyses with data obtained from case reports and case series were conducted in the absence of comparative clinical studies. It is planned to update the recommendations at regular intervals in line with the results of new studies

Intensity And Heart Rate Response Relationship In Different Treadmill Protocols

Araştırmanın amacını farklı protokollere katılan sporcuların yüklenme düzeyleriyle, kalp atım hızı (KAH) cevaplarının ilişkilendirilmesi oluşturmaktadır. 13 erkek sporcu (yaş: 22,594,25 yıl, antrenman yaşı 13,253,2 yıl, boy uzunluğu 175,557,10 cm, vücut ağırlığı 74,569,98 kg ve vücut yağ yüzdesi %10,263,68) devamlı, aralı ve artırmalı olmak üzere 3 farklı koşu bandı protokolünde birer gün arayla koşu testine katılmışlardır. Devamlı ve aralı koşu protokolleri öncesi 9km/s hızda, artırmalı koşu protokolünde ise 7km/s hızda 5 dakikalık ısınma koşusu yaptırılmıştır. Ardından devamlı koşu protokolünde 5 dakika boyunca hız her dakika 1km/s, 5. dakikadan sonra her dakika 0.5km/s artırılmıştır. Aralı koşu protokolünde hız dakikada 1km/s artırılmış ve her hız artırımı öncesinde 30sn pasif dinlenme verilmiştir. Artırmalı koşu protokolünde 8.05km/s sabit hız kullanılmış, ilk 3 dakikada eğim %0, 3 dakikadan sonra %2.5'a çıkartılmıştır. Sonrasında her 2 dakikada %2.5 artırılmıştır. Tüm koşu protokollerinde test bitiminde hız 4km/s'e indirilmiş ve sporcu 5 dakikalık soğuma koşusu yapmıştır. KAH değerlerindeki artış ve azalışa ait ilişki değerleri ve katsayıları için regresyon analizi uygulanmıştır. Sonuç olarak devamlı koşu protokolünde, KAHmaksdeğerine en kısa sürede ulaşıldığı, yüklenme aralığı yüzdeleri bakımından devamlı ve aralı koşu protokollerinde eşik üstü geçirilen süre arttırmalı koşudan daha fazla olmasıyla bu iki protokolün daha yüksek şiddette yüklenme oluşturduğu sonucuna varılmaktadır.The aim of this study was to define the correlation between the levels of exercise intensity of athletes using different protocols and the heart rate responses (HRR). 13 male athletes (age: 22,59±4,25 years, training age: 13,25±3,2 years, height: 175,55±7,10 cm, weight: 74,56±9,98 kg, body composition: 10,26±3,68 participated in running tests every other day on different treadmill protocols which are continous, interval and incremental. A 5 minute warm-up run was applied at 9km/h before continous and interval protocols and at 7km/h before incremental protocol. After that, the speed of treadmill was increased by 1km/h at at every minute during 5 minutes and then by 0.5km/h every minute in continuous protocol. In interval protocol, however, the speed was increased by 1km/h per minute and before each increase, a 30-second passive rest was given. In incremental protocol, the treadmill speed was set at 8.05km/h with the gradient starting at 0% for the first 3 minutes and then it was raised to 2.5%. Afterwards, it was increased by 2.5% every 2 minutes. At the end of all running protocols, the speed was decreased to 4 km/h and the athletes had a 5-minute cool-down run. A regression analysis was used to find the correlation coefficient on the increase and decrease of heart rate values. In conclusion, it was observed that maximum heart rate value was reached fastest in continuous protocol, regarding the percentage of intensity intervals, as the duration of the threshold time is longer in continuous and interval running protocols than that of the incremental running, it can be concluded that these two running protocols produce higher exercise intensity
