EARLY IRON AGE POTTERY FROM HALICARNASSUS PENINSULA: TWO NEW AMPHORA FRAGMENTS FROM PEDASA
No full textWOS: 000336913900003The recent surveys and excavations carried out in Pedasa and its territory, one of the Lelegian settlements in the Halicarnassus Peninsula, present new evidence which sheds light on the Early Iron Age settlements and the culture of the region. Pedasa enjoyed a broad territory extending from the Konacik district to the ridge of Torba. The site is characterized by local burial customs, particularly the large number of burial tumuli. The pottery encountered in these tumuli enhances our knowledge of the local pottery style of coastal Caria. The amphora fragments evaluated in this study are among the finds uncovered in one of the tumuli located at Sivricam Tepe to the south of Pedasian acropolis
Time-resolved in-situ analysis of densification of nano-boron carbide under superimposed electric and thermal fields with energy dispersive x-ray diffraction
No full textBoron carbide (B4C) is characterized by high melting temperature, high hardness, and low density. Such exceptional properties make B4C is an important covalent solid which is considered the foremost material of choice for high-technology applications. However, low diffusivity caused by the highly directional and stiff character of the covalent bond makes the thermally activated sintering of B4C difficult. Highly covalent bonded ceramics are sintered with hot pressing and spark plasma sintering (SPS) to achieve high densities. However, these two techniques are limited to simple shape components and costly, involving expensive equipment. Pressureless sintering of B4C is desired to avoid expensive die designs and post sintering diamond machining, but very high sintering temperatures close to melting point is necessary to obtain high densities. Recently introduced flash sintering technique is a low voltage two electrode method which enhances the densification of ceramics. The sintering time and temperature can be reduced substantially with flash sintering that provide essential energy savings. In this study, the feasibility of flash sintering of nanoparticulate boron carbide is investigated. Firstly, we analyze the thermal expansion of boron carbide under different constant electric field strength to obtain fundamental data to provide insight into understanding of flash sintering. The electric field strength has an effect on the non-linear thermal expansion coefficients of B4C, and expansion becomes more non-linear with the increase of applied e-field. Secondly, the variety of non-isothermal and isothermal flash sintering experiments have been performed to achieve densification of B4C. By using low voltage, densities up to 95% of the theoretical density have been accomplished at temperatures as low as 711oC and short times on the order of few minutes. The very low process densification temperatures and time clearly indicate that mass transport in this nanoparticulate system under the action of both thermal and electrical fields are of an electrochemical origin. The implementation of ultrahigh energy EDXRD method in flash sintering of B4C enables us to monitor the evolution of nanoparticulate matter at the unit cell scale that is otherwise not possible with conventional Bragg-Brentano-method. EDXRD analysis reveals the transient anomalous unit cell expansion which is consistent with the flash sintering phenomena, and we demonstrate that flash sintering of B4C is possible with help of new coupling mechanism called the galvanomechanical effect. Moreover, we investigate the effect of different flash sintering conditions on densification of B4C.Ph.D.Includes bibliographical referencesby Hulya Bice
Comparison the effects of using different organic acids on gelatin extracted from cultured sea bream (Sparus aurata) scales
No full textIn the current study two different types of organic acids were used in gelatin extraction. The scales of gilthead seabream (Sparus aurata) were used as a source of gelatin. Also the effects on quality and gelling properties of used organic acids were investigated. Due to the determined gel strength values, high quality gelatins were produced in both groups with good functional properties. Total yield of the obtained products was found to be 31.10% (acetic acid), and 31.19% (propionic acid). According to the results, scale gelatin recovered by using acetic acid was found more suitable for industry with its 8.9 degrees C gelling point. Foam formation ability of acetic acid group was determined as 2.8 where the value of propionic was 3.0. Organic acids difference did not effect the colour of the product, both groups determined colourless and transparent. Result of the study showed that recovered collogen from gilthead sea bream scales have the potential to be an alternative source of gelatin with the determined functional properties.Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [112O952]; Ege University Scientific Research Projects Coordination UnitEge University [2012-SUF-021]This study was supported and funded by The Scientific and Technological Research Council of Turkey (TUBITAK) Project No. 112O952 and supported by Ege University Scientific Research Projects Coordination Unit (Project No. 2012-SUF-021).

Nursing students' perspectives on assisting cancer patients
No full textObjective: The objective of this study was to examine the experiences of student nurses who have provided care to cancer patients. Methods: A mixed method approach consisting of semistructured focus groups (n = 61) and a survey questionnaire (n = 129) was used in the study. Student nurses were first interviewed, and then, a questionnaire was developed for them to answer. Following the content analysis, three themes and 19 subthemes were identified. Frequency and percent were used for qualitative data. Results: Among the student nurses, 80.6% reported that working with cancer patients was “difficult.” Difficulties experienced by the student nurses included patients rejecting their care, a large number of problems cases encountered when providing care to cancer patients, communication problems (38.0%), working with patients and attendants who fear death, and problems arising from family attendants who obstruct care. The majority of students experienced patients fearing death (28.7%) and felt feelings such as pity (71.1%), sadness (50.0%), and fear of cancer (41.9%) during their internships in oncology clinics. Conclusions: Students should be supported by instructors and oncology nurses, and nursing curricula should contain topics on how to best approach cancer patients

Assessing the Validity and Reliability of the Peristomal Skin Lesion Assessment Instrument Adapted for Use in Turkey.
No full textMany ostomy patients experience peristomal skin lesions. A descriptive study was conducted to assess the validity, usability, and reliability of the Peristomal Skin Lesions Assessment instrument (SACS instrument) adapted to Turkish from English. The SACS Instrument consists of 2 main assessments: lesion type (utilizing definitions and photographs) and lesion area by location around the ostomy. The study was performed in 2 stages: 1) the SACS language was changed and its content validity established; and 2) the instrument\'92s content validity and inter-observer agreement (consistency) were determined among pairs of nurses who used the tool to assess peristomal skin lesions. Patients (included if they were >18 years old and receiving treatment/observation at 1 of the 4 participating stomatherapy units) and 8 stomatherapy nurses also completed appropriate sociodemographic questionnaires. Of the 393 patients screened during the 7-month study, 100 (average age 56.74 \'b1 14.03 years, 55 men) participated; most (79) had a planned operation. A little more than half (59) of the patients had colorectal cancer and 28 had their stoma site marked preoperatively by a stomatherapy nurse. The most common peristomal skin lesion risk factors were having an ileostomy and unplanned surgery. The content validity index of the entire Turkish SACS instrument was 1, and the inter-observer agreement Kappa statistic was very good (K = 0.90, 95% CI 0.80- 0.99). Individual SACS item K values ranged from K = 0.84 (95% CI 0.63\'961) to K = 1 (95% CI 1). Most (62.5%) nurses found the terms and pictures used in the SACS classification adequate and suitable, and 50% believed the Turkish version of the SACS instrument was a valid and suitable assessment tool for use by Turkish stomatherapy nurses. Validity and reliability studies involving larger and more diverse patient and nurse samples are warranted
