Hybrid EEFIT mission to february 2023 Kahramanmaraş earthquake sequence

The southwestern part of Türkiye was hit on 6 February 2023 by an Mw 7.8 (epicentre:Pazarcık) and then an Mw 7.5 earthquake (epicentre: Elbistan). The event was followed by tensof thousands of aftershocks including the Mw 6.3 event on 20 February (epicentre: Uzunbağ).This paper reports on the preliminary findings of the mission organised by the UK’s EarthquakeEngineering Field Investigation Team (EEFIT) to the Kahramanmaraş Earthquake sequence ofFebruary 2023. This mission followed a hybrid model, combining field and remote investigationtechniques, to investigate the characteristics of the earthquake sequence, its impact on buildingsand infrastructure, as well as the efficacy of relief, response and recovery operations. The keymessages include that the building stock is hard to categorise which brings along difficulties withdamage assessment, that the recovery and reconstruction require multi-sectoral engagement ofkey stakeholders, and that the auditing and quality control mechanisms within the constructionindustry need revisiting in the way forward for better disaster resilience in Türkiye

Deposition of ZnO thin films by RF&DC magnetron sputtering on silicon and porous-silicon substrates for pyroelectric applications

In this study, the temperature response of ZnO thin film is investigated in an attempt to enhance its pyroelectric performance. The film is formed on PS and Si substrates utilizing RF&DC magnetron sputtering deposition technique. The outcome of study reveals a pyroelectric coefficient observed from ZnO film on PS which is 40 times higher than that on Si and a pyroelectric voltage as high as 2.4 V due to PS's profound effect on film formation, large surface to volume area and low thermal conductivity. Thus, this study can lead the way to a robust, reliable and more efficient pyroelectric operation of ZnO with employment of PS structure. © 2017 Elsevier B.V

Spinal trauma is never without sin: A tetraplegia patient presented without any symptoms

SUMMARY: Spinal cord injuries are amongst the most dangerous injuries, leading to high mortality and morbidity. Injured patients are occasionally faced with life-threatening complications and quality-of-life changing neurological deficits. Thoracic and cervical spinal segments are the most effected sites of injury and a wide range of complications including paraplegia, respiratory and cardiovascular compromise secondary to autonomic dysfunction or tetraplegia may ensue. We aim to draw attention to the progressive nature of the neurological deficits in a patient admitted asymptomatically. Also, we would like to discuss the importance of swift diagnosis and management in such patients. In asymptomatic patients in whom no fractures are diagnosed with CT scans, a neurological examination should be repeated several times to exclude any neurological injuries that were missed. MRI should be ordered in an emergency setting even though it is not frequently used as a diagnostic modality. This should be done especially in patients without any fractures on CT but with neurological signs. ÖZET: Spinal kord yaralanmaları yüksek mortalite ve sakatlanma oranlarına neden olan en tehlikeli yaralanmalar arasında sayılmaktadır. Etkilenen hastalarda sıklıkla yaşamı tehdit edici komplikasyonlar ve hastanın hayat kalitesini etkileyen nörolojik bozukluklar gelişebilmektedir. Torakal ve servikal segmentler en sık etkilenen yaralanma yerleri olup, hastalarda otonom disfonksiyona ikincil parapleji, solunumsal ve kardiyovasküler bozukluklar gelişebilir ya da tetrapleji görülebilir. Bu olgu sunumuyla, semptomsuz olarak başvuran bir hastanın nörolojik bozukluklarının ilerleyici doğasına dikkat çekmek istiyoruz. Ayrıca, bu tip hastalarda hızlı tanı ve yönetimin önemini tartışmak istemekteyiz. Semptomsuz olarak başvuran ve bilgisayarlı tomografilerinde kırık saptanmayan hastalarda nörolojik muayene sık aralıklarla tekrarlanarak herhangi bir nörolojik hasarın gelişip gelişmediği izlenmelidir. Acil servislerde manyetik rezonans görüntüleme sık kullanılan tanı testlerinden biri olmamasına rağmen özellikle bilgisayarlı tomografisinde herhangi bir patoloji tespit edilmeyen ancak nörolojik bulguları mevcut olan hastalarda mutlaka istenmelidir.
