Anatomical and histological analysis of the salpinx and ovary in Anatolian wild goat (Capra aegagrus aegagrus)

Background: This study determined the anatomical and histological structure of the salpinx and ovary of the Anatolian wild goat (C. aegagrus aegagrus). Materials and methods: The salpinges and ovaries from four wild goats of similar ages were used. These goats were brought to the Kafkas University Wildlife Rescue and Rehabilitation Centre (Kars, Turkey) for various reasons such as traffic accidents or firearm injury, but either could not be saved or were euthanased. Results: The mean length of the ovary was 13.22 +/- 1.27 mm, width was 8.46 +/- +/- 0.88 mm, thickness was 5.67 +/- 0.79 mm, and weight was 0.59 +/- 0.17 g. The mean length of the salpinx was 58.11 +/- 14.02 mm, width was 0.80 +/- 0.22 mm, thickness was 0.41 +/- 0.01 mm, and weight was 0.30 +/- 0.08 g. The salpinx consisted of three different regions (infundibulum, ampulla, and isthmus). These regions consisted of tunica mucosa, tunica muscularis, and tunica serosa. Prismatic epithelial cells were observed in the lamina epithelialis of the tunica mucosa in every region. Conclusions: The data resulting from this study regarding anatomical and histological structures of the salpinx and ovary in the genital system organs of Anatolian wild goat will support other studies seeking to improve reproductive efficiency and eliminate the danger of extinction of this species

Sıvılaşabilir zeminler üzerinde yer alan binalarda sıvılaşma etkisinin doğal sismik taban izolatörü olarak kullanılması

TÜBİTAK İÇTAG Proje01.06.20061985 Meksika depreminde Mexico-City’de ve 1999 Kocaeli Depreminde Adapazarı’nda, suya doygun silt-kil karışımları üzerinde yer alan sığ radye temeller kalıcı deplasmanlara maruz kalmıştır. Yumuşak yüzey zeminleri, sığ yer altı suyu, kısıtlı temel derinliği, ve derin alüvyon çökelleri her iki durumda temel deplasmanlarına ilişkili olarak görülen ortak özelliklerdir. Edinilen deneyime bağlı olarak, düzgün temel oturmaları aşırı olması durumunda dahi bina türü yapıların deprem sonrası kullanılabilirliğini etkilemediği, ancak temellerde meydana gelecek eğilmelerin yapının kullanılabilirliği bakımından özellikle sorun yarattığı bilinmektedir. Bu çalışmada, ince daneli zeminler üzerinde yer alan sığ radyelerin sismik yükler altındaki kalıcı eğilme potansiyelinin öngörülebilmesi amacıyla basitleştirilmiş bir yöntem geliştirilmiştir. Adapazarı’nda temel deplasmanlarının belirgin olarak meydana geldiği sahalarda karşılaşılan silt-kil karışımlarının drenajsız kayma ve deformasyon davranışları, anisotropik olarak konsolide edilmiş doğal zemin örnekleri üzerinde bir dizi standart ve hızlı monotonik, ve gerilme-kontrollü çevrimsel üç eksenli testler gerçekleştirilerek incelenmiştir. Test sonuçları, bu zeminlerin kayma dayanımının Kocaeli depremi ile kıyaslanabilir yükler altında önemli oranda değişmediğini; ancak plastik birim deformasyon özelliklerinin, yükleme moduna ve yük seviyesinin monotonik kayma dayanımına göre seviyesine bağlı olduğunu ortaya koymaktadır. Laboratuvar sonuçlarına bağlı olarak, doğrusal olmayan zemin-temel-yapı sisteminin tepkisi tekderece-serbestisi olan elastik-mükemmel plastik titreşir sistem davranışına indirgenmiştir. Bu idealize sistemin doğal peryodu basit zemin-yapı-etkileşimi denklemlerine bağlı olarak ifade edilmiştir. Temelde taşıma kapasitesi yenilmesine sebep olan ve yapısal kütleye uygulanan pseudo-statik akma ivmesi, sonlu elemanlar yöntemi ile tahmin edilmektedir. Neticede, temellerin dönme potansiyeli sistemin doğrusal olmayan tepkisi kullanılarak tahmin edilmektedir. Deprem hız dalgası peryodunun saha peryodu ile tutarlı olduğu derin alüvyon sahaların sismik mukabelesinin, düşük taşıma kapasitesine sahip temel sistemlerinin elastik olmayan davranışı üzerindeki etkisi belirgindir. 1 Geliştirilen yöntemin öngörü kapasitesi vaka verileri kullanılarak denenmiştir. Yöntemin, düşük sismik taşıma kapasitesinin söz konusu olduğu durumlar dışında dışında, kalıcı temel eğilmesi potansiyelini tutarlı olarak tahmin edebildiği gözlemlenmiştir. Sapmalar, düşük mukavemetli sistemlerin asimetrik davranışa olan hassasiyeti ve sismik talepteki belirsizlik ile açıklanmıştır.Occurrence of displacements of the shallow mat foundations resting on saturated silt-clay mixtures were reported in Mexico City during 1985 Mexico Earthquake, and in Adapazarı during 1999 Kocaeli Earthquake. Soft surface soils, shallow ground water, limited foundation embedment and deep alluvial deposits were the common features pertaining to such foundation displacements in either case. Experience shows, while uniform foundation settlements, even when excessive, do not limit post earthquake serviceability of building structures; whereas, tilting is particularly problematic in this respect. In this study, a simplified methodology is developed to estimate the seismically induced irrecoverable tilting potential of shallow mats on fine saturated soils. The undrained shear and deformation behavior of silt-clay mixtures encountered at the Adapazarı sites with significant foundation displacements are investigated through a series of standard and rapid monotonic, and stress-controlled cyclic triaxial tests conducted over anisotropically consolidated natural soil samples. Test results show that, while the shear strength of these soils do not significantly degrade under means of loading comparable to that of Kocaeli earthquake, their plastic strain accumulation characteristics critically depend on the mode of loading as well as the relative levels of applied load with regard to the monotonic strength. Based on the results of laboratory tests, the response of nonlinear soil-foundation-structure system is reduced to a single-degree-of-freedom oscillator with elastic-perfectly plastic behavior. The natural period of the system is expressed by simplified soil-structure-interaction equations. Pseudo-static yield acceleration, which is required to initiate the foundation bearing capacity failure when applied to the structural mass, is estimated by the finite-element method. Eventually, the tilting potential of the foundations is estimated utilizing inelastic response of the nonlinear oscillator. Response of the deep alluvium sites, which involves velocity pulses with periods consistent with the fundamental site period, is significant in determination of inelastic response of low bearing capacity systems. 3 Predictive capability of the methodology developed is tested with actual case data. The methodology is observed to predict irrecoverable tilting potential of foundations consistent with the observations, except for the cases with low seismic bearing capacity. Deviations are explained considering the sensitivity of low-strength systems to asymmetrical behavior and uncertainties involved in seismic demand

Two Electrons in a Quantum Dot: A Unified Approach

Low-lying energy levels of two interacting electrons confined in a two-dimensional parabolic quantum dot in the presence of an external magnetic field have been revised within the frame of a novel model. The present formalism, which gives closed algebraic solutions for the specific values of magnetic field and spatial confinement length, enables us to see explicitly individual effects of the electron correlation.Comment: 14 page

Norm Values of Head Circumference in Turkish Children

Objective: Measuring head circumference is a quick, simple, cheap, noninvasive and reliable procedure for determining underlying brain size and provides information about risk for medical problems. Growth percentages of head vary from one community to another. Methods: We aim to create head circumference growth curves for children aged 0-18 years in Turkish community. Measurements were performed by same person using a rigid and calibrated tape meter. In addition, the parents were asked to fill out a questionnaire with variables that could affect children's growth. Results: Data analysis has shown that there is no relationship between the children's head circumference and whether there exists someone with a large/small head circumference in their families, or the average monthly income of their families and the parent’s education level. Only the independent variables child’s school performance, birth weight, nutrition, smoking are significantly effective on the HC measures of boys at alpha=0.05 level. For girls, only the independent variables birth weight and nutrition form are significantly important in explaining the variability of HC at the level of alpha=0.05. One gram increase in birth weight causes a 0.001 cm increase in the HC of both genders. In addition, head circumference growth curves were created for both genders to include all children aged 0-18. Conclusions: Our study offers recent and gender-specific head circumference norms. These new values can be used more effectively in child follow-up

Multivariate sensor data analysis for oil refineries and multi-mode identification of system behavior in real-time

Large-scale oil refineries are equipped with mission-critical heavy machinery (boilers, engines, turbines, and so on) and are continuously monitored by thousands of sensors for process efficiency, environmental safety, and predictive maintenance purposes. However, sensors themselves are also prone to errors and failure. The quality of data received from these sensors should be verified before being used in system modeling. There is a need for reliable methods and systems that can provide data validation and reconciliation in real-time with high accuracy. In this paper, we develop a novel method for real-time data validation, gross error detection and classification over multivariate sensor data streams. The validated and high-quality data obtained from these processes is used for pattern analysis and modeling of industrial plants. We obtain sensor data from the power and petrochemical plants of an oil refinery and analyze them using various time-series modeling and data mining techniques that we integrate into a complex event processing engine. Next, we study the computational performance implications of the proposed methods and uncover regimes where they are sustainable over fast streams of sensor data. Finally, we detect shifts among steady-states of data, which represent systems' multiple operating modes and identify the time when a model reconstruction is required using DBSCAN clustering algorithm.Turkish Petroleum Refineries Inc.

Parental psychological distress associated with COVID-19 outbreak: A large-scale multicenter survey from Turkey

Aims: Pandemics can cause substantial psychological distress; however, we do not know the impact of the COVID-19 related lockdown and mental health burden on the parents of school age children. We aimed to comparatively examine the COVID-19 related the stress and psychological burden of the parents with different occupational, locational, and mental health status related backgrounds. Methods: A large-scale multicenter online survey was completed by the parents (n = 3,278) of children aged 6 to 18 years, parents with different occupational (health care workers—HCW [18.2%] vs. others), geographical (İstanbul [38.2%] vs. others), and psychiatric (child with a mental disorder [37.8%]) backgrounds. Results: Multivariable logistic regression analysis showed that being a HCW parent (odds ratio 1.79, p <.001), a mother (odds ratio 1.67, p <.001), and a younger parent (odds ratio 0.98, p =.012); living with an adult with a chronic physical illness (odds ratio 1.38, p <.001), having an acquaintance diagnosed with COVID-19 (odds ratio 1.22, p =.043), positive psychiatric history (odds ratio 1.29, p <.001), and living with a child with moderate or high emotional distress (odds ratio 1.29, p <.001; vs. odds ratio 2.61, p <.001) were independently associated with significant parental distress. Conclusions: Parents report significant psychological distress associated with COVID-19 pandemic and further research is needed to investigate its wider impact including on the whole family unit. © The Author(s) 2020
