Syntaxonomic Analysis Of Forests, Shrubs, And Steppes Of Tavşan Mountain(Amasya, Turkey), Cengi̇z Yildirim, Erkan Yalçin, Arzu Cansaran, Hasan Korkmaz

Turkish Journal of Botany

The aim of this study is to reveal the syntaxonomical structure of Tavşan Mountain in the Euxinian transition area in northern Turkey. Eight plant associations were determined and classified using the Braun?Blanquet phytosociological approach. Detrended correspondence analysis was also used to reveal the environmental heterogeneity among the plant associations. Raunkiaer life form ratios of syntaxa were calculated. Shannon?Wiener index values also were determined for each plant association. The results of this study suggested that which environmental factors could be decisive in community diversity and syntaxonomical status.


Design And Test Of An Apparatus For Transient Measurements Of The Thermalconductivity And Volumetric Heat Capacity Of Solids, Florian Gather, Ekrem Güneş, Peter J. Klar Jan 2019

Design And Test Of An Apparatus For Transient Measurements Of The Thermalconductivity And Volumetric Heat Capacity Of Solids, Florian Gather, Ekrem Güneş, Peter J. Klar

Turkish Journal of Physics

Knowledge of the thermal conductivity (κ) of solids is crucial for all thermoelectric devices. A new approach in transient measurement to determine this value as well as electric conductivity (σ) and the Seebeck coefficient (S) is presented here. This approach can be combined with current steady-state methods. A cylindrical sample is mounted between two heat-flux sensors that can be heated or cooled at their outer ends. The input signals defining the heat fluxes at the sensors can be any arbitrary function of time, although some waveforms yield more valid results. The method is evaluated by employing a one-dimensional numerical model …


Modified Newton's Gravitational Law From Deformed Poisson Bracket, Ch'ng Han Siong Jan 2019

Modified Newton's Gravitational Law From Deformed Poisson Bracket, Ch'ng Han Siong

Turkish Journal of Physics

In this paper, we obtain the modified Newton's gravitational law from deformed Poisson bracket motivated by the generalized uncertainty principle. The modified Newton's gravitational law that we obtain contains a term that plays an important role only in the regime of first order in $\bar{\beta}$. In the ordinary situation or condition, the modified Newton's gravitational law reduces to the conventional Newton's gravitational law.


Various Paths To The Spontaneous Growth Of $P$-Form Fields, Fethi̇ Mübi̇n Ramazanoğlu Jan 2019

Various Paths To The Spontaneous Growth Of $P$-Form Fields, Fethi̇ Mübi̇n Ramazanoğlu

Turkish Journal of Physics

We show that $p$-form fields can go through spontaneous growth due to various couplings in gravity theories, forming a new example of spontaneous tensorization. Generalizing the spontaneous scalarization theory of Damour and Esposito-Farèse where the original idea has been applied to different fields from vectors to spinors has received high levels of interest in recent years. We first review this existing literature on spontaneous growth in gravity, and then apply the known mechanisms to $p$-forms. We show that one can induce spontaneous growth in $p$-forms for each of the regularized instability mechanisms, which was not the case for other types …

Turkish Journal of Earth Sciences

The Hamech area is located in the west of Kuh-e-Shah volcano-plutonic complex, close to the boundary between the Lut Block and Sistan Suture Zone (SSZ), and is composed of monzonite to diorite porphyries and rare gabbro that intruded into older volcanic rocks. U-Pb zircon dating indicates an age of 36.9 ± 1 Ma for gabbro (Late Eocene, Priabonian) and 38.6 ± 0.5 Ma for dacite (Late Eocene, Bartonian). Geochemically, the studied intrusions are dominantly I-type, high-K calc-alkaline, and metaluminous features. Primitive mantle-normalized trace-element spider diagrams of these rocks present enrichment in ion lithophile elements such as Cs, Rb, Ba, K, …

Miocene Sediment Mineralogy Of The Lower Chelif Basin (Nw Algeria):Implications For Weathering And Provenance, Fatiha Hadji, Abbas Marok, Ali Mokhtar-Samet

Turkish Journal of Earth Sciences

Mineralogical investigations of clay and nonclay minerals were conducted on the Miocene sediments from three sections of the lower Chelif basin, northern Algeria. Bulk rock analyses of Miocene sediments show that these clastic sediments are dominated by variable mineralogical compositions and concentrations. Quartz is the dominant mineral through the three stratigraphic intervals and calcite (except in the upper layers) and dolomite are lacking in the Messinian deposits. The clay mineralogy is dominated by smectite (24%) and mixed-layer illite-smectite (I-S) (22%) during the Burdigalian-Langhian, illite (36%) and kaolinite (28%) in the Tortonian, and illite (49%) and I-S (20%) in the Messinian …

Relationship Between The Anisotropy Of Magnetic Susceptibility And Development Of The Haymana Anticline, Central Anatolia (Turkey), Murat Özkaptan, Erhan Gülyüz

Turkish Journal of Earth Sciences

Integrated structural and anisotropy of magnetic susceptibility (AMS) analyses were carried out on the Campanian- Maastrichtian shale-mudstone dominated sedimentary sequences (Haymana Formation) cropping out within the doubly plunging Haymana Anticline in Central Anatolia (Turkey). In order to understand the relationship between the development of magnetofabrics and the tectonic processes, six sites from different parts of the anticline were sampled and analyzed. AMS lineations from 634 cylindrical samples and structural data were collected in the field. The results show very high correlation with the structural trend of the region and indicate that the maximum susceptibility vector (k1) is almost parallel to …

Blue Sky At Midnight - Earthquake Lightning, Neil Whitehead, Ülkü Ulusoy Jan 2019

Blue Sky At Midnight - Earthquake Lightning, Neil Whitehead, Ülkü Ulusoy

Turkish Journal of Earth Sciences

Earthquake light, emerging from the ground as flashes at night (neglecting other more minor forms), usually has a white hemispherical center and blue outer part. The blue resembles daytime blue sky. Its existence is increasingly verified, with about 80 videos on the web to mid-2017. However, the light must be differentiated from power-grid faults, so sound/color/form/length criteria were developed in this paper through examination of many videos. Light should be coseismic (i.e. when the S-waves arrive), hemispherical, not during a storm, less than 1 s long, without fire or smoke, and without many rapid color changes. Warnings about camera artifacts …

Journal Articles: Biostatistics

Nutritional status is a well-recognized prognostic indicator in chronic obstructive pulmonary disease (COPD); however, very little is known about the relationship between lung function and saturated fat intake. We used data from the cross-sectional National Health and Nutrition Examination Surveys (NHANES) to assess the relationship between saturated fatty acid (SFA) intake and lung function in the general US adult population. Adults in NHANES (2007⁻2012) with pre-bronchodilator spirometry measurements and dietary SFA intake were included. Primary outcomes were lung function including forced expiratory volume in one second (FEV₁)

Pso Trained Hybrid Intelligent Classifier Using Wavelet And Statistical Features For Pipeline Leak Classification, Hanan A. R., Wael A., Ibraheem H. M. Al-Dosari

Iraqi Journal of Computers, Communications, Control and Systems Engineering

One of the main problems in the oil industrial field is the leakage in transporting pipelines due to its effect on human society , environment, and money loss. Therefore, the bottleneck for most researches in this subject is to minimize false alarm rate (FAR) for the adopted leak detection method. Although some recent methods succeed in classifying the existence or absence of the leak as a binary classification problem. But this paper proposed a novel leak detection technique which predicts the leak location and estimates its size within certain pre-defined ranges. In order to simulate the environmental conditions for real-time …

Speed Controller Of Three Phase Induction Motor Using Sliding Mode Controller, Dr.Farazdaq R., Walaa H.

Iraqi Journal of Computers, Communications, Control and Systems Engineering

A Sliding Mode Control (SMC) with integral surface is employed to control the speed of Three-Phase Induction Motor in this paper. The strategy used is a modified field oriented control to control the IM drive system. The SMC is used to calculate the frequency required for generating three phase Voltage of Space vVector Pulse Width Modulation (SVPWM) invertor. When the SMC is used with current controller, the quadratic component of stator current is estimated by the controller. Instead of using current controller, this paper proposed estimating the frequency of stator Voltage whereas the slip speed is representing a function of …


Holmes, Humility, And How Not To Kill Each Other, John D. Inazu Jan 2019

Holmes, Humility, And How Not To Kill Each Other, John D. Inazu

Scholarship@WashULaw

Oliver Wendell Holmes’s dissent in Abrams v. United States is one of the intellectual anchors of modern First Amendment doctrine. In the century since Abrams, we have witnessed changes in society, technology, and politics that have shaped and reshaped the contours of our First Amendment landscape. But not everything has changed — some aspects of our human experience remain remarkably similar to the context in which Holmes wrote. One unchanged aspect of the human condition is our inability to know with certainty. Confronted with this reality in his own day, Holmes at times gestured toward a foundationless relativism. But even …

Course Taking And Teacher Data-Driven Decision Making Self-Efficacy And Anxiety: A Secondary Analysis, Valerie M. Hamilton Jan 2019

Course Taking And Teacher Data-Driven Decision Making Self-Efficacy And Anxiety: A Secondary Analysis, Valerie M. Hamilton

Graduate Research Theses & Dissertations

An expanding culture of accountability in education has led to an influx in the amount and types of data teachers are expected to collect and use to increase student achievement. Research has identified data-driven decision making (DDDM) as a way for teachers to use educational data to promote more effective instruction and ultimately, to better student outcomes. Despite available data and research that supports the use of DDDM, using it to make instructional decisions is still a struggle for teachers. Therefore, this study looks at the relationship between DDDM-related coursework and teacher self-efficacy and anxiety for DDDM. In theory, DDDM-related …

Explicitly Teaching Scientific Argumentation: Using Action Research To Study High School Science Readiness And Detracking, Ami Lefevre

Dissertations

Access to advanced-level science courses can be difficult for those students who start in a tracked system. Tracking is an educational practice where students are assigned to different classes based on ability level. African American and Hispanic students are most at risk since most minority students are found in the lower level track (Burris, 2014; Mehan, 2015; Oakes, 2005). This investigation used an action research approach to determine how explicitly taught elements of scientific argumentation would impact student mastery of argument skills and influence instructional practices by a professional learning community. A mixed method study was used to collect qualitative …
