Advantages of early intervention with arterial embolization for intra-abdominal solid organ injuries in children

PURPOSEActive bleeding due to abdominal trauma is an important cause of mortality in childhood. The aim of this study is to demonstrate the advantages of early percutaneous transcatheter arterial embolization (PTAE) procedures in children with intra-abdominal hemorrhage due to blunt trauma.METHODSChildren with blunt abdominal trauma were retrospectively included. Two groups were identified for inclusion: patients with early embolization (EE group, n=10) and patients with late embolization (LE group, n=11). Both groups were investigated retrospectively and statistically analyzed with regard to lengths of stay in the intensive care unit and in the hospital, first enteral feeding after trauma, blood transfusion requirements, and cost.RESULTSThe duration of stay in the intensive care unit was greater in the LE group than in the EE group (4 days vs. 2 days, respectively). The duration of hospital stay was greater in the LE group than in the EE group (14 days vs. 6 days, respectively). Blood transfusion requirements (15 cc/kg of RBC packs) were greater in the LE group than in the EE group (3 vs. 1, respectively). The total hospital cost was higher in the LE group than in the EE group (4502 USD vs. 1371.5 USD, respectively). The time before starting enteral feeding after first admission was higher in the LE group than in the EE group (4 days vs. 1 day, respectively).CONCLUSIONEarly embolization with PTAE results in shorter intensive care and hospitalization stays, earlier enteral feeding, and lower hospital costs for pediatric patients with intra-abdominal hemorrhage due to blunt trauma

Reconciling the stratigraphy and depositional history of the Lycian orogen-top basins, SW Anatolia

Terrestrial fossil records from the SWAnatolian basins are crucial both for regional correlations and palaeoenvironmental reconstructions. By reassessing biostratigraphic constraints and incorporating new fossil data, we calibrated and reconstructed the late Neogene andQuaternary palaeoenvironments within a regional palaeogeographical framework. The culmination of the Taurides inSWAnatolia was followed by a regional crustal extension from the late Tortonian onwards that created a broad array of NE-trending orogen-top basins with synchronic associations of alluvial fan, fluvial and lacustrine deposits. The terrestrial basins are superimposed on the upper Burdigalian marine units with a c. 7 myr of hiatus that corresponds to a shift from regional shortening to extension. The initial infill of these basins is documented by a transition from marginal alluvial fans and axial fluvial systems into central shallow-perennial lakes coinciding with a climatic shift from warm/humid to arid conditions. The basal alluvial fan deposits abound in fossil macro-mammals of an early Turolian (MN11–12; late Tortonian) age. The Pliocene epoch in the region was punctuated by subhumid/humid conditions resulting in a rise of local base levels and expansion of lakes as evidenced by marsh-swamp deposits containing diverse fossilmammal assemblages indicating late Ruscinian (lateMN15; late Zanclean) ageWe are grateful for the support of the international bilateral project between The Scientific and Technological Research Council of Turkey (TUBITAK) and The Russian Scientific Foundation (RFBR) with grant a number of 111Y192.

Usage of segmentation for noise elimination in reconstructed images in digital holographic interferometry

In this paper, we propose to enhance the image in digital holography by using an artificial neural network and an iterative algorithm with Nakamura's approach based on segmentation. It is well known that reconstructed three-dimensional (3D) images suffer from noise in digital holography. In addition, obtaining 3D reconstructed images takes a long time due to large pixel numbers in reconstructed images and lack of memory in the system. The segmentation process is an application that overcomes these problems. Therefore, we focus on the implementation of segmentation for image enhancement. In addition, the results of the segmentation process for both methods are compared in terms of image enhancement. Later, the relative errors are calculated. © 2018 TÜBITAK

Türkiye’de 2022 Yılı Asgari Ücret İstisnasının Vergi Takozuna Tahmini Etkileri

ürkiye’de 2021’in son ayında ücret artış oranları için aralık ayı enflasyon verileri beklenirken Hükümet tarafından Gelir Vergisi ve Damga Vergisi kanunlarına getirilen bir düzenlemeyle brüt ücretin bir kısmı istisna kapsamına alınır ve ücretlere enflasyon rakamlarına ek ve örtülü olarak bir zam yapılır. Esas olarak çalışanların ücretlerini ilgilendirse de bu düzenleme, işverenlerin işgücü talebi neticesinde katlandıkları maliyetleri de oransal olarak azaltıcı niteliktedir. Buna göre, getirilen istisnalar brüt ücreti kapsasa da brüt ücret, işverenlerin maliyetidir. Đşverenlerin işçilere yaptıkları ücret ödemeleriyle yasalar gereği işçiler adına ödemek zorunda oldukları bazı yükümlülükler, brüt ücretin unsurlarıdır. Đşverenlerin her bir işçi istihdamı karşılığında ücret ödemesi dışında üstlenmek zorunda oldukları bu maliyetler, vergi takozu olarak adlandırılır. Türkiye, iki yılda bir yayınlanan OECD verilerine göre 2020 yılında tüm ücret seviyeleri için yüzde 38,8 ortalama vergi takozu oranıyla, grup ortalamasının iki puan üzerindedir. Asgari ücrete getirilen vergi istisnasının vergi takozunu azaltıcı etkisinin olacağı ve bunun OECD ortalamasının altında gerçekleşeceği tahmin edilmektedir. Bu çalışmada 2020 yılına kadar olan dönemde Türkiye’nin vergi takozu istatistikleri ele alınarak (i) 2022 yılının Ocak ayı itibariyle getirilen asgari ücret istisnası sayesinde vergi takozu oranın düşeceği, lakin istisna nedeniyle ödenmeyen vergi doğrudan net ücretlere yansıdığından işverenin lehine sonuç doğurmayacağı, (ii) hem vergi takozu oranının hem de işveren maliyetini azaltılması için brüt ücret içerisinde yer almayan yasal kesintilerde indirim yapılması gerektiği ve (iii) asgari ücret istisnasının çalışanların asgari ücretlileşmesi yolunda etkiler doğuracağı ve gelir dağılımında adaleti bozucu nitelikte olacağı savunulmuştur.While waiting for December inflation data for wage increase rates in Turkey in the last month of 2021, a part of the gross wage is included in the exemption with a regulation brought by the Government to the Income Tax and Stamp Tax laws, and an implicit increase is made to the wages in addition to the inflation figures. Although it mainly concerns the wages of the employees, this regulation also proportionally reduces the costs incurred by the employers as a result of the labor demand. Accordingly, although the exceptions include the gross wage, the gross wage is the employer's cost. Some of the obligations that employers have to pay on behalf of workers, as required by law, are elements of gross wage. These costs, which employers have to undertake other than paying wages for each worker employment, are called tax wedges. According to OECD data published biennially, Turkey is two points above the group average with an average tax wedge rate of 38.8 percent for all wage levels in 2020. It is estimated that the tax exemption brought to the minimum wage will have a reducing effect on the tax wedge and this will be below the OECD average. In this study, Turkey's tax wedge statistics for the period until 2020 are taken into account, (i) thanks to the minimum wage exemption introduced as of January 2022, the tax wedge rate will decrease, but the tax not paid due to the exemption will not result in favor of the employer since it directly reflects on net wages, (ii) It has been argued that legal deductions that are not included in the gross wage should be reduced in order to reduce both the tax wedge rate and the employer's cost, and (iii) the minimum wage exemption will have effects on the minimum wage of the employees and will distort the justice in the income distribution

Crack Detection by Optical Voice Recorder Based on Digital Holography

The detection of crack on materials is an important issue in industry. On the contrary to conventional methods, such as manual inspection, sensor detection, and image processing techniques, a new simple method to detect the crack is proposed with optical voice recorder based on digital holography in this paper. Holograms obtained with sound waves passing through the materials are recorded by using the digital holography technique. Temporal behavior of the sound wave passing through the material, which is obtained from these holograms, gives image of crack. In this article, cracks in various materials are determined by the proposed new method, and crack images obtained with this new system are presented. © 2019, The Author(s).116E303 Türkiye Bilimsel ve Teknolojik Araştirma Kurumu 2016-75737790-04We acknowledge the director of research and development of UÇAR Metal Company who contributed towards the article.

Comparing of phase shifting method and one-dimensional continuous wavelet transform method for reconstruction using phase-only information

The one-dimensional continuous wavelet transform method has some advantages in hologram reconstruction, when used in the only phase, compared with the phase shifting method. This paper aims to discuss these advantages. One advantage is related to image quality. Another advantage is less power spent and saving time, because the one-dimensional continuous wavelet transform method uses only one hologram and the phase shifting method uses four holograms for recording and reconstruction processes. One nal advantage is that the one-dimensional continuous wavelet transform method can also be used in real-time applications. Within the context of the ongoing optimization studies, this study will make a signi cant contribution to the literature because of these mentioned advantages.The one-dimensional continuous wavelet transform method has some advantages in hologram reconstruction, when used in the only phase, compared with the phase shifting method.

Non-contact performance analysis of the core materials by digital holographic interferometry

In this study, it is intended to determine how a core material behaves under the influence of a static magnetic field (MF), which causes magnetic losses in electrical machines. In addition, it is aimed to design an optical system, which can determine the performance of the core materials under MF effect. First, when standard core materials are exposed to a MF, these materials make rotational movements. The amount of rotation is then calculated and the work amount done after this rotation is tracked. Consequently, from the work quantities, it can be decided whether the materials are good core materials or not. This shows that the optical system can make a non-contact performance analysis for the materials in certain thicknesses, which may be the core material. Thus, this system can be used to determine whether the newly manufactured core material is a good one according to the work quantities obtained for standard equivalents. At the same time, this is the first study about performance analysis of core materials achieved by optical methods. © The Institution of Engineering and Technology
