Firing deformation in large size porcelain tiles. Effect of compositional and process variables

Ponencia presentada en el XV Congreso Mundial de la Calidad Del Azulejo y del Pavimento Cerámico (QUALICER 18), celebrado en Castellón (Spain) los días 12 y 13 de febrero de 2018.The manufacture of porcelain stoneware has undergone a spectacular growth in the last years, as a result of the good technical and functional performance associated to the impervious feature of the sintered product, together with the great technological advance that the ceramic tile manufacturing sector is experiencing [1]. To such an extent, that today, porcelain stoneware is the most demanded product for use in flooring surfaces, but at the same time, it is becoming important to incorporate in other applications such as ventilated facades

Corinthian capitals of Augustian period from stratoniceia with Egyptian influence

Corinthian capitals, formed in the second half of the 5th century B.C. were common from the Hellenistic Period onwards in Anatolian architecture as carrying architectural elements with rich ornaments which obtain the structure an aesthetic look. Corinthian capitals are seen on many structures in the ancient city of Stratoniceia after the first half of the second century B.C. Especially during the Augustian Period the structural activities increased in the city. The gymnasium, theatre, bouleuterion and the north street constructions with their Corinthian capitals are the sign of this fact. Stratoniceia, as it was renamed by the Seleucids, offers capitals dated to the Augustian Period which carry Egyptian and Cilician influences. Three Augustian capitals which form the content of this article are the best examples of this fact. Both local and exterior features can be determined on these three capitals. Based on these examples it is possible to understand much better the rich decorative style applied to the architectural monuments in the city

A cross-sectional analysis of sagittal knee laxity and isokinetic muscle strength in soccer players

PubMed ID: 15532002In this cross-sectional study, sagittal knee laxity and isokinetic strength of knee extensor and flexor muscle groups were measured and differences related to leg dominance were evaluated. A total of 44 healthy male soccer players (who had trained regularly at least for the last five years) and 44 sedentary people as their control counterparts were involved in this study. All participants were tested using a KT-1000 knee arthrometer for knee laxity. Isokinetic concentric knee peak torque and hamstring/quadriceps (H/Q) ratio were also measured at 60, 180, 300°/s through a Cybex 2-340 dynamometer. Posterior laxity in the non-dominant side of soccer players was significantly higher than in the dominant side (p < 0.005) while there were no significant anterior and total anteroposterior (total AP) laxity differences in both groups. Soccer players had significantly lower anterior and total AP laxity values than controls (p < 0.0001) while there was no significant difference between posterior laxity values in both sides. Dominant extremity demonstrated significantly higher knee flexor peak torque and H/Q ratio at 180°/s in soccer players (p < 0.05). Similarly in sedentary controls, H/Q ratio at 60°/s of the dominant side was significantly higher than that in the non-dominant side (p < 0.05). Soccer players had significantly higher extensor and flexor peak torque values and H/Q ratios than sedentary subjects for both extremities. In both groups, there were no significant correlations between knee laxity and isokinetic knee extensor and flexor strength and H/Q ratios except weak negative correlation between posterior knee laxity and isokinetic extensor peak torque at 60, 180 and 300°/s (p < 0.005, r = -0.43, p < 0.05, r = -0.39, p < 0.05, r = -0.32 respectively) in the non-dominant side of soccer players and at 300°/s (p < 0.05, r = -0.32) in the non-dominant side of controls. Soccer players demonstrated significantly less sagittal knee laxity and higher isokinetic strength of the knee flexors and extensors compared to sedentary controls. Isokinetic strength difference was found to be higher for the flexor muscle group. Further prospective studies are needed to explain whether the increased H/Q ratio decreases the risk of ligamentous injury

THE COMPARISON OF SOME PHYSICAL, PHYSIOLOGIC AND ANTHROPOMETRIC PARAMETERS OF JUNİOR MALE NATIONAL AND AMATEUR BADMINTON PLAYERS

Bu çalışmada; yıldız milli ve amatör düzeyde erkek badmintoncuların bazı fiziksel, fizyolojik ve antropometrik parametrelerinin karşılaştırılması amaçlandı. Araştırmaya gönüllü 10 yıldız milli (yaş:11.20 ± 0.6) ve 10 amatör (yaş:11.80 ± 0.63) erkek badmintoncu olmak üzere 20 sporcu katıldı. İstatistiksel veriler SPSS paket programında Mann Whitney U testi ile değerlendirildi. Yıldız milli ile amatör sporcular arasında fiziksel ve fizyolojik testlerden 30, 60 m, zik-zak (4x10m), pençe kuvveti, dikey sıçrama ve reaksiyon zamanı testlerinden sağ, sol el ışık, sol el ve sol ayak ses testi parametreleri yönünden mili sporcular lehine anlamlı fark bulunmuştur. Milli sporcular ile amatör sporcular arasında yapılan antropometrik ölçümlerden vücut yağ oranı ile çevre ölçümlerinden karın çevresi ölçümlerinde milli sporcular lehine anlamlı fark tespit edilmiştir. Badminton milli ve amatör sporculara yapılan ölçümlerden omuz, göğüs, kalça, üst kol, üst ve alt bacak çevresi, otur uzan esnekliği, anaerobik güç, sağ el ve sağ ayak ses, sağ ve sol ayak ışık reaksiyon testleri arasında anlamlı fark bulunmamıştır. Sonuç olarak; araştırmada karşılaştırılan yıldız milli ve amatör sporcular arasındaki farkın nedeni, yıldız milli düzeyde sporcu olabilmek belli düzeyde fiziksel, fizyolojik ve antropometrik parametrelere sahip olmayı gerektirmektedir.The aim of this study was the comparison of some physical, physiologic and anthropometric parameters of junior national and amateur level male badminton players. For volunteering purpose 20 sportsmen were participated 10 national Junior (age:11.20 ± 0.6) and 10 amateur (age:11.80 ± 0.63). The statistical analysis was evaluated by the use of SPSS package program containing Mann Whitney U test. The physical and physiological tests were done among national and amateur sportsmen, 30, 60 m, Zig-zag (4x10m), vertical jump and an important difference was found in the reaction time tests of right, left hand light, left hand ve left foot sound test parameters of the national sportsmen. As for the anthropometric measurements which were done between national and amateur sportsmen an important difference was determined in body fat rate with circumference measurement of waist measurement. The measurement were done the Badminton National and amateur sportsmen: An important difference was not found among shoulder, chest, hip, upper arm and leg, lower leg circumference, sit and reach flexibilty, anaerobic strength, right hand and right foot sound, right and left foot light reaction tests. As a result: In this research the comparison among the national junior and amateur sportsmen, it is seen that to be a national junior level sportsman it is neccesary to have a certain level of physical, physiological and anthropometric paramaters.

Investigation of Turkish nurses frequency and knowledge of administration of intramuscular injections to the ventrogluteal site: Results from questionnaires

Background Intramuscular injection is important in the administration of parenteral medication and is a frequently-performed nursing responsibility. Objective The objective of this study was to identify the frequency of use of the ventrogluteal site and the level of nurses' knowledge of administering an intramuscular injection to this site. Design A descriptive cross-sectional study was conducted of nurses working in four hospitals (n = 362). Data collection tools included a 12 item sociodemographic questionnaire and a 24 item questionnaire on knowledge of the ventrogluteal site for intramuscular injection. Findings 17.1% of participants reported using the VG site frequently in intramuscular injections. On the other hand, 35.9% reported that they do not use the VG site in intramuscular injections just because they are not used to giving injections on this site. Level of knowledge of ventrogluteal site was also limited with the mean score of correct answers from 24 questions being 14.37. Conclusion It was found in the study that nurses' knowledge of the ventrogluteal site was limited, and they are not preferentially using the ventrogluteal site for intramuscular injections to adults even though it is recommended in recent nursing literature. © 2017 Elsevier Lt

What do patients really know about cardiopulmonary rehabilitation: A cross-sectional survey study

Background. Although it is known that cardiopulmonary rehabilitation (CPR) reduces mortality and morbidity, it is not widely implemented as is in Turkey. One factor might be lack of demand since the levels of knowledge and awareness among patients who are eligible for CPR seem to be insufficient. Aim. It is aimed to investigate the level of awareness and knowledge of CPR among patients with cardiopulmonary problems. Design. Cross-sectional survey study Setting. Outpatient Methods. Knowledge regarding CPR was assessed by questionnaires given to 690 patients recruited in seven university hospitals and six training and research hospitals in which either comprehensive or limited CPR services are available. Population. Patients who have cardiopulmonary problems Results. Of the patients, 34.7% were given information on CPR by healthcare staff, and 25.3% reported that their source of information was physicians. Although 49-9% of the patients knew that they needed to exercise for their cardiac/pulmonary problems, only 23.4% and 32.1% of those were aware that fast walking and climbing stairs, respectively, would not pose a risk to their cardiac/pulmonary health. The majority of the patients believed that activities of daily living, which comprise the most important component of exercise-based CPR, were harmful for their cardiopulmonary health. We found that 31.1% of the patients exercised regularly. During their stay at the hospital, certain kinds of exercises were suggested to 62.7% of the patients, and 34.7% of these patients performed various exercises. Of the patients who were given detailed information on cardiopulmonary rehabilitation, 69% stated that they would be willing to participate in a similar program. Conclusion. Although nearly half of the patients stated that they needed CR, it was observed that the ratio of patients who had true knowledge of CPR was low among patients. It is imperative to furnish patients with information on CPR, both in the field of PMR and throughout Turkey, and to put more effort into running those services effectively. Furthermore, we should make an effort to increase the level of liaison between patients and physicians and other healthcare professionals who participate in the treatment of cardiac/pulmonary patients
