Mathematical modelling of electrical potential difference in a non-uniform electric field
This work offers an unproblematic teaching tool for the instruction of challeng-ing concept of electric potential difference in a non-uniform electric field. Specifically, mathematical modelling process is employed and managed to comprehend and teach exceedingly difficult concepts of uniform and non-uniform electric fields, electrical potential difference, scalar products of vectors and also concept of path integral. In order to accomplish those tasks, initially a basic conducting panel/sheet, that is simply a wet cardboard, is designed as a part of the apparatus, together with a dc power supply, a multi meter and connecting cables. The established method is interesting in the sense that the 3D wet cardboard is novel, very practical and minimal costing, hence the approach offers physics educators fresh teaching routes and opportunities to clarify the puzzling concept of electrical potential difference and further
Assessment of the Prevalence of Pulp Stones in a Sample of Turkish Central Anatolian Population
Objective. The aim of this study was to determine the prevalence of pulp stones (PS) in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. Materials Methods. A retrospective study was performed using bitewing radiographs of 814 patients ranging in age from 15 to 65. All data (age, sex, and location) was obtained from the files. These patients were analyzed for pulp stones. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Results. Of the patients, 462 (56.8%) were female and 352 (43.2%) were male. Sixty (12%) had one or more teeth that contained pulp stones. Pulp stones were identified in 518 (63.6%) of the subjects and in 2391 (27.8%) of the teeth examined. Pulp stone occurrence was significantly more common in the females than in males. With the increasing of age, the prevalence of pulp stones increased. Molars had statistically more pulp stones than premolars. Pulp stones were significantly more common in the maxilla compared with mandible. Conclusion. Prevalence of pulp stones in Turkish population was 27.8% but further larger-scale studies are required to assess its prevalence in the general population to compare it with other ethnic groups
Psikolojik danışman adaylarının empati düzeyleri ve kişisel anlam profilleri: Boylamsal bir çalışma
The aim of this longitudinal study was to examine the empathy levels and personal meaning profiles of
the psychological counseling candidates studying at university. The research was based on descriptive method. The
main purpose was to comparatively examine the changes in the empathy levels and personal meaning profiles of the
participants with respect to years. The study group consisted of 36 participants (30.6% of whom were boys, and
69.4% of whom were girls) who were studying at university between the academic years of 2015 and 2019. The data
were collected once each year (first, second, third, and fourth grades) from the participants involved in the study
group. In order to collect data, which were then analyzed using Statistical Package (SPSS), One Way Anova with
repeated measures and the Friedman Test were used. The findings revealed that the basic empathy levels of the
prospective psychological counselors did not change during their undergraduate studies, whereas the level of their
pursuit of personal meaning in religion and intimacy did change. Counselor Candidates received the highest score in
the first year and the lowest score in the fourth year on the dimensions of religion and intimacy of the Personal
Meaning Profile scale.Bu araştırmanın amacı, üniversitede öğrenim görmekte olan psikolojik danışman adaylarının empati düzeyleri

Continuous auditing effectiveness as a fraud deterrent
İşletme yapılarının giderek büyümesi ve karmaşıklaşması ile yöneticilerin işletme faaliyetleri üzerindeki
kontrol gücü, azalmaya başlamakta ve buna bağlı olarak işletmelerde hata ve hile riski de artmaya
başlamaktadır. Bu bağlamda işletmelerin büyüklüğü ne olursa olsun hilelerin ortaya çıkartılması ve bu
eylemleri önlemeye yönelik uygulamaların gerçekleştirilmesi gerekmektedir. Hile önlemede birçok
yöntem kullanılmakla birlikte en çok kullanılan yöntemlerden biri de sürekli denetim tekniğidir. Sürekli
denetim, gerçek zamanlı muhasebe sistemleri altında dijital ortamlarda verilerin kaydedilmesi,
raporlanması ve denetimini ifade etmektedir. Kavramsal olarak tasarlanan bu çalışmanın amacı, sürekli
denetimin hile önlemedeki rolünü incelemektir. Bu amaçla ilk olarak hata ve hile kavramları ve türleri ile
ilgili bir kavramsal bir çerçeve oluşturularak denetim ve sürekli denetim kavramı açıklanmıştır. Son
olarak hile önlemede sürekli denetimin rolü incelenmiştir.With the continuous growth and increasing complexity of the business structures, control power of the
managers on the business activities began to decrease and subsequently fault and fraud risks in the
businesses started to increase. In this context, eliciting the frauds and execution of the applications aimed
to prevent such actions no matter the size of the businesses is necessary. Various methods are being
utilized in preventing frauds and continuous auditing technique is one of the most commonly used
method. Continuous auditing means registry, report and auditing of the data given in digital mediums
under the real time accounting systems. The goal of this study which was conceptually designed is to
analyze the role of continuous auditing in preventing the frauds. For this purpose, auditing and concept of
continuous auditing were first explained by creating a conceptual framework regarding the fault and fraud
concepts and their types. Finally, the role of continuous auditing was analyzed in the prevention of frauds
Growth performance and some morphological traits of Honamli goat kids until weaning age in extensive condition
The aim of this study was to determine growth performance until weaning age of Honamli goat kids reared in extensive conditions in Turkey. Study was carried out with 75 Honamli kids (44 female, 31 male), kept at the Research and Training Farm of the Faculty of Veterinary Medicine of Mehmet Akif Ersoy University in Burdur, Turkey. Birth weight of male kids was higher than that female kids and also birth weight of single kids was higher than that twin kids. Live weight in the 120th day of male, female, single and twin kids were 24.4 kg, 22.0 kg, 26.9 kg and 21.2 kg, respectively. Withers height, body length, chest circumference and nose length on the 120th day were detected as 61.6 cm, 58.4 cm, 59.2 cm and 18.4 cm, respectively in female Honamli kids. Same measurements were 63.9 cm, 61.7 cm, 62.7 cm and 20.0 cm for males Honamli kids
The effects of lycopene on hepatic ischemia/reperfusion injury in rats
There is a very little information about the protective effect of lycopene (LYC) against hepatic ischemia-reperfusion injury. The present study was designed to examine the possible protective effect of the strong antioxidant and anti-inflammatory agent, LYC, on hepatic ischemia/reperfusion injury. For this purpose, rats were subjected to 45 min of hepatic ischemia followed by 60 min of reperfusion period. LYC at the doses of 2.5 and 5 mg/kg body weight (bw) were injected intraperitoneally, 60 min prior to ischemia. Upon sacrification, hepatic tissue samples were used for the measurement of catalase (CAT) activity and malondialdehyde (MDA) levels. Also, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were assayed in serum samples. As a result of the use of LYC at the doses of 2.5 and 5 mg/kg bw; while improvements of the ALT, AST, LDH and MDA values were partial and dose-dependent, the improvement of CAT activity was total and dose-independent (p < 0.05). Our findings suggest that LYC has a protective effect against ischemia/reperfusion injury on the liver
Forgiveness Flexibility
Forgiveness flexibility is the skill to minimize the negative effect of an event by using cognitive, affective and behavioral skills while taking a stand at the end of an injurious process. A number of studies were conducted to test the flexibility of the structure of forgiveness. The theoretical structure, structural validity and the confirmatory factor analysis supported the theoretical structure of forgiveness flexibility. The criterion validity evaluated in similar manners was found high. Forgiveness flexibility designed as a three dimensional structure and its sub-dimensions was confirmed theoretically as the recognition of forgiveness andthe internalization of forgiveness through insight and its practice
Evaluation of the diagnostic value of platelet indices in pediatric acute appendicitis
Objective: Abdominal examination findings in pediatric acute appendicitis (AA) significantly vary by age. Therefore, grading systems have been developed for diagnosing pediatric appendicitis, and laboratory and radiological findings have an important role in this diagnosis. However, there is a need to develop new parameters for diagnosing AA. This study aimed to investigate the diagnostic value of platelet indices in AA. Methods: This retrospective, observational study included 207 pediatric patients who were admitted to the Emergency Department and operated on for AA. The patients were divided into three groups on the basis of their surgical and histopathological findings (non-AA, uncomplicated AA, and complicated AA). Results: There was no significant difference in the mean platelet volume/platelet count (MPV/PC) ratio among the groups. The white blood cell (WBC) count and the MPV/PC ratio showed a significant negative relationship (r = −0.239). The specificity for MPV was 61.8% and the sensitivity was 68.8%. Receiver operating curve analysis of WBC and MPV showed significance for diagnosing AA. Conclusion: There is a negative, but weak, relationship between the WBC count and the MPV/PC ratio. However, the MPV/PC ratio could be a useful parameter for diagnosing pediatric AA according to receiver operating curve analysis. © The Author(s) 2020
