Study of e+e- →π+π-π0ηc and evidence for Zc (3900)± decaying into ρ±ηc STUDY of e+e- →π+π-π0ηc ... M. ABLIKIM et al.
No full textWe study the reaction e+e-→π+π-π0ηc for the first time using data samples collected with the BESIII detector at center-of-mass energies s=4.226, 4.258, 4.358, 4.416, and 4.600 GeV. Evidence of this process is found and the Born cross section σB(e+e-→π+π-π0ηc), excluding e+e-→ωηc and ηηc, is measured to be (46-11+12±10) pb at s=4.226 GeV. Evidence for the decay Zc(3900)±→ρ±ηc is reported at s=4.226 GeV with a significance of 3.9σ, including systematic uncertainties, and the Born cross section times branching fraction σB(e+e-→π Zc(3900)±)×B(Zc(3900)±→ρ±ηc) is measured to be (48±11±11) pb, which indicates that e+e-→π Zc(3900)±→πρ±ηc dominates the e+e-→π+π-π0ηc process. The Zc(3900)±→ρ±ηc signal is not significant at the other center-of-mass energies and the corresponding upper limits are determined. In addition, no significant signal is observed in a search for Zc(4020)±→ρ±ηc with the same data samples. The ratios RZc(3900)=B(Zc(3900)±→ρ±ηc)/B(Zc(3900)±→π±J/ψ) and RZc(4020)=B(Zc(4020)±→ρ±ηc)/B(Zc(4020)±→π±hc) are obtained and compared with different theoretical interpretations of the Zc(3900)± and Zc(4020)±. © 2019 authors.

Study of the decays psi(3686) -> gamma chi(cJ) -> gamma(p)over-barK*(+)Lambda + c.c. and psi(3686) -> (p)over-barK*(+) Lambda plus c.c.
No full textBased on the data sample of 448.1×106 ψ(3686) events collected with the BESIII detector at BEPCII, we present a study of the decays ψ(3686)→γχcJ→γp̄K∗+Λ+c.c. and ψ(3686)→p̄K∗+Λ+c.c. The branching fractions of χcJ→p̄K∗+Λ+c.c. (J=0, 1, 2) are measured to be (4.8±0.7±0.5)×10-4, (5.0±0.5±0.4)×10-4, and (8.2±0.9±0.7)×10-4, respectively, where the first uncertainties are statistical and the second systematic. The branching fraction of ψ(3686)→p̄K∗+Λ+c.c. is measured to be (6.3±0.5±0.5)×10-5. All these decay modes are observed for the first time. © 2019 authors. Published by the American Physical Society
Freedom of The Press in Coalition Governments: True Path Party and Social Democratic People's Party/Republican People's Party Case (1991-1996)
No full textThe DYP-SHP/CHP coalition government between 1991 and 1996 became the longest-running coalition in Turkey. In this process, it was observed that although there were changes in the parties and the leaders that formed the government, the unity continued. During the partnership period established as a result of the agreement of parties in different ideologies, radical transformations were experienced in many areas, especially in economics and law. On the other hand, throughout the country, terrorist incidents have increased and many people were killed. In addition to these developments, significant changes and problems were experienced in the press during this period. In this context, legal arrangements made to the press and the general situation of the press were examined under the direction of the DYP-SHP/CHP coalition government within the scope of this study. This study discusses whether the press is free in the DYP-SHP/CHP coalition government. In this context, the aim of the study is to show how the freedom of the press and the laws enacted are shaped. This study is crucial since it reflects the state of the press during the DYP-SHP/CHP coalition period. In this study, the descriptive method and written sources related to the area were used. As a result of this study, it can be stated that during the period of the DYP-SHP/CHP coalition government, intense pressure and control imposed on the press were determined and freedom of the press was clearly restricted
Improved measurements of the absolute branching fractions of the inclusive decays D+(0) -> phi X
No full textBy analyzing 2.93 fb(-1) of e(+)e(-) annihilation data taken at the center-of-mass energy root s = 3.773 GeV with the BESIII detector, we determine the branching fractions of the inclusive decays D+-> phi X and D-0 -> phi X to be (1.135 +/- 0.034 +/- 0.031)% and (1.091 +/- 0.027 +/- 0.035)%, respectively, where X denotes any possible particle combination. The first uncertainties are statistical, and the second are systematic. We also determine the branching fractions of the decays D -> phi X and their charge conjugate modes (D) over bar -> phi(X) over bar separately for the first time, and no significant CP asymmetry is observed

No full textIn this study, the role of negative thoughts of special education teachers on job satisfaction and burnout is examined. The study was carried out with 287 participants from schools in Istanbul. The sample was selected by easy sampling method. The study is a quanlitative research. Maslach Burnout Inventory is used to determine the level of burnout, The Minnesota Satisfaction Questionnaire is used to scale level of job satisfaction on participants and negative automatic thoughts are measured by Automatic Thoughts Scale. T-Test, ANOVA, correlation and regression analyzes were used to evaluate the data. According to the results, negative automatic thoughts of teachers have been found to increase their burnout and decrease their job satisfaction. When the results were examined, it was found that the burnout levels of the participants differed significantly with gender, marital status, graduation status and economic status; job satisfaction levels of teachers differ according to the variables of gender, age, graduation status and economic status; and their negative automatic thoughts differ significantly according to gender, age, length of working years, graduation status and economic status. © 2019, Ankara University.

Measurement of branching fractions of psi(3686) -> phi eta ', phi f(1) (1285) and phi eta(1405)
No full textUsing a sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector, we perform a study of the decay psi(3686) -> phi pi(+)pi(-)eta. The branching fraction of psi(3686) -> phi eta' is determined to be (1.51 +/- 0.16 +/- 0.12) x 10(-5), which is consistent with the previous measurement but with significantly improved precision. The resonances f(1)(1285) and eta(1405) are clearly observed in the pi(+)pi(-)eta mass spectrum with statistical significances of 18s and 9.7 sigma, respectively. The corresponding product branching fractions are measured to be B(psi(3686) -> phi f(1)(1285), f(1)(1285) -> pi(+)pi(-)eta) = )1.03 +/- 0.10 +/- 0.09) x 10(-5) and B(psi(3686) -> phi eta(1405), eta(1405) -> pi(+)pi(-)eta) = (8.46 +/- 1.37 +/- 0.92) x 10(-6). These results are used to test the perturbative QCD "12% rule.

No full textNesnelerin kendileri dışında bir olguya atıfta bulunduğu temel ilkesi ile çalışmalar
yapan göstergebilim, maddi kültürü, kültürel anlamı üzerinden okuyarak nesnelerin
iletişim yeteneklerini ortaya koymaktadır. Maddi kültür ögelerinden birisi olan
giyime yönelik göstergebilimsel yaklaşımda anlam, giyim paradigmaları içerisinden
yapılan seçim ve yüksek uzlaşıma dayalı dizim ile oluşmakta, simgesel düzeyde
gerçekleşen bir iletişim dizgesini meydana getirmektedir. Öte yandan, giyim
kodunun okumasında, vericinin gönderilmesini amaçladığı anlam ile alıcının
iletiden çıkarımsadığı anlamın farklı olmasına sebep olan değişkenler söz konusu
olabilmektedir. Çalışmada bu kod açımında anlam sapmasına sebep olan değişkenler
örnekler ile açıklanmıştır. Bu iletişim dizgesinde: alıcının vericininkine denk ya
da benzer bir kültürel arka plana sahip olmaması, alıcının ilgili giysinin okuması
için gerekli art alan bilgisine sahip olmaması, alıcı ve vericinin toplumdaki farklı
deneyim alanlarına sahip olmaları, gösterenlerin değişik bölgelerde farklı simgesel
referanslarının olabilmesi giyim göstergelerinin göstergebilimsel çözümlemedeki
değişkenleri olduğu sonucuna varılmıştır

Immune histochemical study of KI-67 level and ribonucleic acid in the process of healing of burn wounds after treatment with drugs containing dexpanthenol and ceramide
No full textCeramides are structural components of the stratum corneum that regulate cell proliferation and differentiation. The study of the effect of the cream containing dexpanthenol and ceramide on the proliferation processes and regeneration of burn wounds in rats. Experimental rats with III-A degree thermal burn were treated separately with the following preparations: Cream with ceramides, cream with dexpanthenol and ceramides and cream "Bepanten". The proliferative-regenerative activity of the drugs was investigated by studying the content of the Ki-67 producing cells and the content of ribonucleic acid (RNA) in the cytoplasm of the granulation tissue fibroblasts. Ceramides contributed to wounds healing, increasing the content of Ki-67 antigenpositive cells, accelerating the formation of scar in the wound. The therapeutic effect of creams with ceramides exceeds the efficacy of the reference preparation “Bepanten” cream. The addition of ceramides to dexpanthenol increases the quality and reduces the wound healing time. © 2019, AMG Transcend Association. All rights reserved

No full text15th European Congress of Psychology (ECP) --JUL 12-14, 2017 -- Amsterdam, NETHERLANDSWOS: 000480458500001Objective: The aim of this study was to analyze the predictive role of depressive symptoms and childhood psychological trauma on impulsive, self-injuring, and suicidal behaviors in groups diagnosed and not diagnosed (control group) with borderline personality disorder (BPD). Methods: The study sample included a diagnosis group (n1=72) that was followed by the psychiatry clinics of a university hospital and a public hospital in Istanbul, Turkey, along with a control group (n2=71) that included healthy volunteers who participated in the study. All study participants were evaluated using the Sociodemographic Information Form, Borderline Personality Inventory (BPI), Beck Depression Inventory (BDI), Hamilton Depression Rating Scale (HAM-D), Barratt Impulsivity Scale (BIS-11), Childhood Trauma Questionnaire (CTQ), Inventory of Statements about Self-injury (ISAS), and Suicide Behavior Questionnaire (SBQ). The study results were analyzed statistically. Findings: First, the hierarchical regression analysis revealed that the BDI and emotional abuse scores in the diagnosis group and the HAM-D in the control group were significant predictors based on the Barratt Impulsiveness Scale. Secondly, the emotional abuse score in the diagnosis group and physical neglect and HAM-D score in the control group were significant predictors of self-injury behavior inventory scores. Thirdly, BDI and sexual abuse scores in the diagnosis group and the emotional and physical abuse scores in the control group were found to be the significant predictors of suicide behavior. Conclusion: Emotional and sexual abuse during childhood and depressive symptoms (BDI) were found to be significant risk factors in terms of impulsive, self-injury and suicidal behaviors in BPD
