Braneworld Mimetic Cosmology

We extend the idea of mimetic gravity to a Randall-Sundrum II braneworld model. As for the 4-dimensional mimetic gravity, we isolate the conformal degree of freedom of 5-dimensional gravity in a covariant manner. We assume the bulk metric to be made up of a non-dynamical scalar field $\Phi$ and an auxiliary metric $\tilde{{\cal{G}}}_{AB}$ so that ${\cal{G}}_{AB}= \tilde{{\cal{G}}}^{CD}\,\Phi_{,C}\,\Phi_{,D}\,\tilde{{\cal{G}}}_{AB}$ where $A, B, ...$ are the bulk spacetime indices. Then we show that the induced conformal degree of freedom on the brane as an induced scalar field, plays the role of a mimetic field on the brane. In fact, we suppose that the scalar degree of freedom which mimics the dark sectors on the brane has its origin on the bulk scalar field, $\Phi$. By adopting some suitable mimetic potentials on the brane, we show that this brane mimetic field explains the late time cosmic expansion in the favor of observational data: the equation of state parameter of this field crosses the cosmological constant line in near past from quintessence to phantom phase in a redshift well in the range of observation. We show also that this induced mimetic scalar field has the capability to explain initial time cosmological inflation. We study parameter space of the models numerically in order to constraint the models with Planck2015 data set.Comment: 17 pages, 7 figure

Thermodynamic analysis of gravitational field equations in Lyra manifold

Considering the Einstein field equations in Lyra manifold, and applying the unified first law of thermodynamics as well as the Clausius relation to the apparent horizon of FRW universe, we find the entropy of apparent horizon in Lyra manifold. In addition, the validity of second law of thermodynamics and its generalized form are also studied. Finally, we use the first law of thermodynamics in order to find the horizon entropy of static spherically symmetric spacetimes. Some results of considering (anti)de-Sitter and Schwarzschild metrics have also been addressed.Comment: Accepted by AHE

Effectiveness of acceptance and commitment therapy on emotion regulation in epileptic patients

Background: Epilepsy can severely affect cognitive-emotional and behavioral function. Using an appropriate treatment method to deal with it in order to treat emotional disorders can be an effective action due to the importance of this disorder. This study attempted to investigate the effectiveness of Acceptance and commitment therapy (ACT) on the emotion regulation in patients with epilepsy. Methods: It was a quasi-experimental study (pretest-posttest design with equal control group) and the sample consisted of 30 patients with epilepsy selected purposefully and assigned into experimental (n=15) and control (n=15) groups randomly. The instrument included the Garnefski et al. Cognitive Emotion Regulation Questionnaire (CERQ). Data were analyzed using SPSS software version 21 conducting MANCOVA and ANCOVA analysis of covariance. Results: The results showed that the ACT decreased negative emotion regulation and also increased positive emotion regulation in patients with epilepsy in the experimental group compared to the control group. The results of one-way analysis of covariance with the pretest control showed that there was a significant difference between the experimental and control groups in patients with epilepsy in terms of positive emotion regulation (F = 100.55, p <0.001) and negative emotion regulation (F = 154.64, p <0.001). Conclusion: It can be argued that ACT reduced negative emotion regulation and increased positive emotion regulation in patients with epilepsy

Effect of conservation tillage systems on growth, yield and yield components of soybean

Conservation tillage systems have been used during recent years in many areas of Iran. In this study, the effect of conservation tillage on soybean yield, yield components and phenological characteristics was evaluated in Golestan province located at the northern Iran. Four different treatments including conventional tillage (CT), minimum tillage (MT), no- tillage with no-till planter (NT-Planter) and no-tillage with no-till grain drill (NT-Grain Drill) were considered. A randomized complete block design with four replications was designed for the experiment. Soybean yield and yield components and some phenological characteristics were measured. Data were analyzed using SAS software and Duncan’s multiple range tests was used to compare the means. The results of two year experiments showed that in year 2012, NT-Grain drill with mean yield of 3612 kg ha-1 had the highest yield while the treatment MT had the lowest yield of 2794 kg ha-1. In year 2013, NT-Planter had the highest yield of 3617 kg ha-1 whereas CT method had the lowest yield of 3054 kg ha-1. It was concluded that NT methods with respect to yield increase are appropriate alternative to replace conventional tillage method in soybean cultivation. Phenological characteristics gave promising response to conservation tillage especially to no tillage

Generalized uncertainty principle and burning stars

Gamow's theory of the implications of quantum tunneling on the star burning has two cornerstones including quantum mechanics and equipartition theorem. It has vastly been proposed that both of these foundations are affected by the existence of a non-zero minimum for length which usually appears in quantum gravity scenarios and leads to the Generalized Uncertainty principle (GUP). Mathematically, in the framework of quantum mechanics, the effects of GUP are considered as perturbation terms. Here, generalizing the de Broglie wavelength relation in the presence of minimal length, GUP correction to the Gamow's temperature is calculated and in parallel, an upper bound for the GUP parameter is estimated

Ilkhanid period archıtecture in Sultaniye City, Zanjan, Iran

İran ve Türkiye iki komşu ülke olarak ortak bir tarih ve kültürel mirasi paylaşmaktalardır. Bu ortak mirasın en önemli belirteçlerinden, İlhanlı İmparatorluğu döneminde her iki ülkede de yapılan ortak mimari yapılarıdır. İran'da Selçuklu İmparatorluğunun sona ermesi ile Selçuklu mimarisi Anadolu'da devam etmiştir ve böylece Anadolu'daki mimari eserlerde Azerbaycan mimarlarının katkısı yadsınamaz bir gerçektir. Buna ek olarak, her iki ülkede Moğol istilasına uğramış ve İlhanlı İmparatorluğu idaresi altında yaşamışlardır. Dolaysıyla, mimari ortaklık açısından İlhanlı döneminin mimari kültürü çok önemlidir. Ancak, 1564 yılında Şah İsmail ile Yavuz Sultan Selim arasındaki savaş ve 1639 yılından sonraki Kasrı Şirin antlaşması sonucunda, iki ülke arasındaki mimari etkileşim giderek azalmaya başladı. İpek Yolunun önemini kaybetmesi nedeniyle bu etkileşim daha da azaldı. Günümüzde Selçuklu ve İlhanlı dönemine ait inşaat ve yapılar her iki ülkede hala mevcudiyetini korumaktadır.. Sultaniye kompleksi olarak bilinen İlhanlı mimari bunlara bir örnektir. Her iki ülkede de Sultaniye kompleksi hakkında bilimsel araştırma ve yorumlar yürütülmesine rağmen, bu eserlerin daha önce derli toplu bir şekilde incelenmemesi ve literatürlerde görülmemesi bizi bu yolda azimli kılmıştır.Iran and Turkey are two neighboring countries and share a common history is a historical and cultural. The most important factor in this common heritage is the common architectural structures made in both countries in the period of The Ilkhanate Empire. At the end of Seljuk Empire in the Iran, Seljuk architecture was continued in the Anadolia so Azerbaijani architects contribution is an undeniable fact. In addition, both countries have suffered Mongolian invasions and lived under the administration of The Ilkhanate Empire. Thus, the period of Ilkhanate architectural culture in terms of partnership is important. However, in 1564, the war between Shah Ismail and Yavuz Sultan Selim and the subsequent Qaser-e Shirin treaty in 1639, architectural interaction between between Safavid Empire and the Ottoman Empire gradually decreased. This interaction with the loss of importance of the Silk Road gradually reduced. Nowadays in both countries construction and building belonging to the Seljuk and Ilhanid period is still remains. Ilkhanates architectural complex known as Sultaniye is a sample of them. However, scientific research and reviews carried out in both contries separately. This works not previously examined in a tidy and does not appear in the literature have made us this way ambitious

Assessment of nursing MSc theses and their levels of evidence

Introduction: Nursing theses are one of the most important sources to provide knowledge and evidence for nursing practice. Thus, this study aimed to investigate the status of research outcomes of nursing MSc theses and their levels of evidence. Methods: This study was a cross-sectional descriptive study. All MSc nursing theses conducted from 1381 to 1390 in Mashhad Nursing and Midwifery School were investigated. The articles extracted from these theses were studied as well .These articles were evaluated in terms of their levels of evidence and type of journal in which they were published. Results: Out of 92 theses conducted in this period, 70 articles were published. 39 percent of these theses were in level 6 (descriptive, quantitative, and cross sectional), 38 percent were in level 4 (case-control and cohort studies) and 23 percent were in level 2 (randomized controlled trial). Comparisons between the first five years and the second five years regarding the study type showed that 38 percent and 77 percent of these theses were experimental and quasi-experimental studies in the first and second periods, respectively. Also 41 percent of the theses were published in journals in the first period whereas this number increased to 82 percent in second period Conclusion: The results showed that the methodology of nursing MSc theses has moved toward clinical interventions and important nursing challenges and their resulting articles have been published in more scientific journals. Given the importance of evidence-based practice, it is necessary to develop individual and organizational mechanisms for promoting the levels of evidence in nursing research
