Background According to the free radical theory, a gradual accumulation of the free radicals normally produced in the body underlies the changes associated with aging. Thyroid hormones (THs) are related to oxidative stress not only due to their stimulation of metabolism but also due to their effects on antioxidant mechanisms. Thyroid dysfunction increases with age; thus, changes in TH levels in elderly individuals could be a factor affecting the development of neurodegenerative diseases. However, the relationship is not always clear, based on current evidence regarding synaptic plasticity. Met ...Daha fazlası

Wireless Sensor Networks (WSNs) have gained importance with a rapid growth in their applications during the past decades. There has also been a rise in the need for energy-efficient and scalable routing along with the data aggregation protocols for the large scale deployments of sensor networks. The traditional routing algorithms suffer from drawbacks such as the presence of one hop long distance data transmissions, very large or very small clusters within a network at the same moment, over-accumulated energy consumption within the cluster-heads (CHs) etc. The lifetime of WSNs is also decrease ...Daha fazlası
Background Surgical masks have become an important accessory of physical activity in daily life due to the COVID-19 pandemic. Aims To determine the efects of the surgical mask on respiratory gas exchange parameters, dyspnoea, and hemodynamic responses during maximal exercise in diferent age groups and gender. Methods Twenty-six healthy participants between 18 and 65 years (mean 37.35±15.99) performed a maximal exercise test twice randomly, with and without a mask. To determine the respiratory gas exchange parameters (peak oxygen consumption (VO2peak), minute ventilation (VE), energy expenditur ...Daha fazlası
This study was designed to test the efficacy of the health promotion program used on maternal-infant attachment, parental self-efficacy, infant development. For this experimental study parallel-group rand-omised control design was used. Data was collected from 64 mother and their infants. The intervention group received the health promotion program in addition to standard care, the control group received only the standard care. Family Information Form, Prenatal Attachment Inventory, Maternal Attachment Inventory, Parenting Self-Efficacy Scale, and Denver II Developmental Screening Tests were u ...Daha fazlası
Limited şirket, Alman kanun koyucusu tarafından evrensel hukuk sistemine kazandırılan bir şirket türüdür. Özellikle aile şirketlerine olan benzerliği sebebiyle sadece küçük ölçekli işletmeler tarafından tercih edileceği düşünülmüşse de beklenen olmamış, zaman içinde orta ölçekli işletmelerin en çok tercih ettiği şirket türü olmayı başarmıştır. Bu çalışmada ilk olarak Roma Hukukundaki şirket kavramı üzerinde durulmuş, daha sonra limited şirketin günümüz hukuk sistemlerindeki varlığı ve gelişimi incelenmiştir. Bu noktada çalışmanın konusu, limited şirketlerin başta Alman Hukuku olmak üzere, İngi ...Daha fazlası

Hypereutectic Al-Si alloys are typically used in applications where wear resistance is required. The primary factor that determines the wear properties is the morphology of Si in these types of alloys. Pouring temperature is one of the ways to control Si size and shape. On the other hand, bifilm defects that may be present in the liquid can significantly alter the morphology of Si acting as a heterogeneous nucleant. Therefore in this work, castings were made at 800 degrees C with varying holding time and the effects of bifilm on the Si morphology was studied. Bifilm content was measured by Red ...Daha fazlası
First results on the longitudinal asymmetry and its effect on the pseudorapidity distributions in Pb–Pb collisions at √sNN = 2.76 TeV at the Large Hadron Collider are obtained with the ALICE detector. The longitudinal asymmetry arises because of an unequal number of participating nucleons from the two colliding nuclei, and is estimated for each event by measuring the energy in the forward neutron-Zero- Degree-Calorimeters (ZNs). The effect of the longitudinal asymmetry is measured on the pseudorapidity distributions of charged particles in the regions |η| < 0.9, 2.8 < η < 5.1 and −3.7 < η < −1 ...Daha fazlası
he second and the third order anisotropic flow, V2 and V3, are mostly determined by the corresponding initial spatial anisotropy coefficients, ε2 and ε3, in the initial density distribution. In addition to their dependence on the same order initial anisotropy coefficient, higher order anisotropic flow, Vn (n > 3), can also have a significant contribution from lower order initial anisotropy coefficients, which leads to mode-coupling effects. In this Letter we investigate the linear and non-linear modes in higher order anisotropic flow Vn for n = 4, 5, 6 with the ALICE detector at the Large Hadr ...Daha fazlası

The strength of forward-backward (FB) multiplicity correlations is measured √ s = 0.9, 2.76 and 7TeV. The measurement is performed in the central pseudorapidity region (|η| < 0.8) for the transverse momentum pT > 0.3GeV/c. Two separate pseudorapidity windows of width (δη) ranging from 0.2 to 0.8 are chosen symmetrically around η = 0. The multiplicity correlation strength (bcorr) is studied as a function of the pseudorapidity gap (ηgap) between the two windows as well as the width of these windows. The correlation strength is found to decrease with increasing ηgap and shows a non-linear increas ...Daha fazlası
Neutral pion and η meson invariant differential yields were measured in non-single diffractive p–Pb colli- sions at √sNN = 5.02 TeV with the ALICE experiment at the CERN LHC. The analysis combines results from three complementary photon measurements, utilizing the PHOS and EMCal calorimeters and the Photon Conversion Method. The invariant differential yields of π0 and η meson inclu- sive production are measured near mid-rapidity in a broad transverse momentum range of 0.3 < pT < 20 GeV/c and 0.7 < pT < 20 GeV/c, respectively. The measured η/π0 ratio increases with pT and saturates for pT > 4 G ...Daha fazlası
