Porous, biphasic CaCO3-calcium phosphate biomedical cement scaffolds from calcite (CaCO3) powder

Tas, A.C.

Article | 2007 | International Journal of Applied Ceramic Technology4 ( 2 ) , pp.152 - 163

Calcite (CaCO3) is a geologically abundant material, which can be used as a starting material in producing biomedical scaffolds for clinical dental and orthopedic applications. Bone-filling applications require porous, biocompatible, and resorbable materials. Commercially available CaCO3 powders were physically mixed, for 80-90 s, with an orthophosphoric acid (H3PO4) solution, which was partially neutralized to pH 3.2 by adding NaOH, to form biphasic, micro-, and macroporous calcite-apatitic calcium phosphate (Ap-CaP) cement scaffolds of low strength. The resultant carbonated and Na-doped Ap-CaP phase in these scaffolds crystallogra . . .phically and spectroscopically resembled calcium hydroxyapatite. Upon mixing CaCO3 powders and the setting solution, carbon dioxide gas was in situ generated and formed the pores. Thus formed scaffolds contained pores over the range of 20-750 µm. Scaffolds were also converted to single-phase Ap-CaP, without altering their porosity, by soaking them in 0.5 M phosphate buffer solutions at 80°C for 36 h in glass bottles. Soerensen's buffer solution was also shown to be able to convert the calcite powders into single-phase Ap-CaP powders upon soaking at 60-80°C. This robust procedure of synthesizing Ap-CaP bioceramics is simple and economical. © 2007 Blackwell Publishing Ltd Daha fazlası Daha az

Deep vein thrombosis in athletes: Prevention and treatment

Altıntaş, F. | Uluçay, Ç.ğ.A.

Book Part | 2012 | Sports Injuries: Prevention, Diagnosis, Treatment, and Rehabilitation , pp.1065 - 1070

Deep vein thrombosis (DVT) can be seen in almost all races and age groups. Although many of the risk factors have been identified and several agents are currently used in its management and prevention, still it is not possible to predict accurately its development, symptoms, and progression to pulmonary embolism (PE) in a particular setting. Every year, at least 100,000 individuals die of DVT and PE in the USA. DVT is a complication usually occurring after hip fractures of the elderly or surgery for total joint replacement or spinal stenosis and mostly affecting elderly and bedridden patients. But, the frequency of DVT is quite high . . . among athletes and professional sport players. In general, DVT risk is 85% greater among athletes when compared to normal population due to the specific risk factors of sports. DVT and PE may be seen in athletes actively taking part in sportive activities, traveling, exposing to sportive trauma, or undergoing surgery for any reason, even at a relatively young age. In this chapter, the risk factors, diagnosis, prevention, and treatment of DVT and PE in athletes are discussed. © Springer-Verlag Berlin Heidelberg 2012 Daha fazlası Daha az

A process oriented supplier quality contorl approach based on dynamic SPC

High quality suppliers are necessary for the success of any organization. To guarantee good quality products from suppliers, it is necessary to optimize the process parameters immediately when deviations of the part quality, that is required by the customer, have been observed. Optimization of process parameters are only possible when an experienced process operator adjusts the parameters of the process manually. Although statistical process control (SPC) enable the quality of conformance to be monitored and special causes of process variability to be identified, it is not well applied in some enterprises due to fact that operators . . .cannot determine the 'out-of-control' position of the process, and the root causes of the quality problems with the limited knowledge they have. Therefore, the presented approach develops a system which combines dynamic control chart with the expert knowledge library. The system is carried out in two steps: the first step, a quality controller checks the product quality according to the reference values, when the process is going to be out of control, the system will give a warning to remind operators to take action exactly and keep the process in normal; in the second step, the system will give the related information and valuable suggestions to operator and help them to take correct action to keep the process in control.

Effect of Polypropylene Fibers on Freeze-Thaw Resistance, Surface Scaling and Flexural Toughness of Concrete

Soylev, TA | Ozturan, T

Conference Object | 2012 | 7TH ASIAN SYMPOSIUM ON POLYMERS IN CONCRETE , pp.737 - 744

Fibers do not provide significant increase in the strength of concrete at low fiber volumes commonly used in practice. The main benefits of fibers result from the control of the width of cracks in concrete. Polypropylene fiber is one of the most popular polymer fibers used in concrete, which has been shown to be effective in controlling the plastic shrinkage at the content of approximately 0.1% by volume. However, as polypropylene fibers are low modulus fibers and used at such low contents, it is difficult to expect an improvement in the crack control of hardened concrete in theory. In the present study, the effect of a multi-filame . . .nt polypropylene fiber on the resistance of concrete to surface scaling and freeze-thaw attack is investigated. Polypropylene fiber reinforced concrete was also tested under flexural load. Two different water/cement ratios were used for concrete production. The results indicated that polypropylene fibers can be beneficial in the control of micro-cracking induced by freeze-thaw cycling and surface scaling. The development of cracks under flexural load was not affected significantly by the presence of the polypropylene fibers Daha fazlası Daha az

A phenomenological study of spatial experiences without sight and critique of visual dominance in architecture

Basvazici-Kulac, B | Ito-Alpturer, M


Architectural phenomenology suggests that the basis of perceptual integrity between the subject and a space is multi-sensorial. However, the advancement of visual representation techniques within architecture has led to predominance of the visual experience over other sensory modalities. As a consequence, the integrity of the user's multi-sensorial appreciation of space has been largely neglected which may impact on the holistic experience of the individual. The present study uses an architectural phenomenology approach to explore user experiences of architectural spaces without reference to visual input: the aim being to elucidate . . .key sensory modalities that drive a synthesis of the spatial experience in the absence of visual cues. In this way, the study aims to highlight the role of the non-visual, as a criticism against the tendency to present architecture as a predominantly visual phenomenon. A qualitative study of spatial experiences from four congenitally blind and three late blind individuals was carried out within the framework of architectural phenomenology. Thus, although all suffered total loss of sight, it was possible to assess the impact of latent visual memories within the second group. In-depth interviews with each participant explored responses to four semi-structured, open-ended questions. They were asked to describe; 1) what an architectural space means to them, 2) the place they live, 3) the most important architectural features that affect their experience either positively or negatively and 4) the most favourable and unfavourable place they had ever been. No time limit was imposed for answering the questions. The answers were audio recorded with permission. All participants judged an architectural space predominantly by its acoustic properties, with no clear difference between the congenital or late blindness subgroups. A frequently mentioned construct was the sense of spaciousness with the acoustic properties of architectural features such as materials and ceiling height identified as critical determinants. Tactile experiences, in the form of air circulation felt on the skin also helped the participants to judge spaciousness. But, it was odour that was often described as the feature that defines the identity of a place. Contrary to common beliefs, tactile experiences using the hands were mentioned least. We conclude that non-visual senses subserve a central role in the formulation of spatial experiences for the visually impaired and postulate that they may have similarly significant impact on the experiences of the visually adept. Designing the properties of different acoustical ambiances to promote a synergy of sensory experiences through, for example, the selection of materials or dimensional adjustment at intersections, voids, openings and atria rather than concentrating on visual impact alone would enrich the environmental experience significantly Daha fazlası Daha az

The development of nationalism in india

Dinçşahin, Şakir | Arslan, Melis

Article | 2013 | Yakın Doğu Üniversitesi Sosyal Bilimler Dergisi6 ( 2 ) , pp.228 - 250

Hindistan’da ortaya çıkan birbirinden farklı ve hatta birbirine rakip milliyetçilik hareketleri koloni yönetiminden bağımsızlık kazanmak amacıyla işbirliği yaparlar. Ancak bağımsızlık sonrası dönemde milliyetçilik hareketleri arasında rekabet işbirliğinin önüne geçer. Sonuç bölünme, ayrılma, pek çok insanın hayatına mal olan nüfus mübadelesi, otoriter yönetim, dinsel-ulusal elitler arasında siyasal ikileşme, siyasi suikastların iktidar devirme aracı olarak kullanılması ve büyük bir demokrasinin yaşaması için gerekli uzlaşının ortadan kalkması olur. This article illustrates that different and competing nationalist movements were able . . . to join forces for the purpose of achieving self-rule in India in the presence of an external hegemonic force (Britain) controlling politics. However, once independence was accomplished, these competing movements have traded self-rule for self-interest. The result has been secession, threats of secession, mass population exchange at great cost to human life, authoritarian rule, political bifurcation along religio-national nomenclatures, violent transfers of power through assassination, and a general absence of compromise necessary for the successful rule of a large democracy Daha fazlası Daha az

Aim. Three incisional ventral abdominal wall hernias were repaired by placing a 20 30cm composite mesh via single incision of 2cm. Methods. All three cases had previous operations and presented with giant incisional defects clinically. The defects were repaired laparoscopically via single incision with the placement of a composite mesh of 20 30cm. Nonabsorbable sutures were needed to hang and fix the mesh only in the first case. Double-crown technique was used in all of the cases to secure the mesh to the anterior abdominal wall. Results. The mean operation time was 120 minutes. The patients were mobilized and led for oral intake at . . . the first postoperative day. No morbidity occurred. Conclusion. Abdominal incisional hernias can be repaired via single incision with a mesh application in experienced centers. © 2011 Umut Barbaros et al Daha fazlası Daha az
