Numerical methods for incompressible viscous flows with engineering applications

A numerical scheme has been developed to solve the incompressible, 3-D Navier-Stokes equations using velocity-vorticity variables. This report summarizes the development of the numerical approximation schemes for the divergence and curl of the velocity vector fields and the development of compact schemes for handling boundary and initial boundary value problems

A general review of concepts for reducing skin friction, including recommendations for future studies

Four main concepts which have significantly reduced skin friction in experimental studies are discussed; suction, gaseous injection, particle additives, and compliant wall. It is considered possible that each of these concepts could be developed and applied in viable skin friction reduction systems for aircraft application. Problem areas with each concept are discussed, and recommendations for future studies are made

Occlusion, TMDs, and dental education

The paradigmatic shift to evidence-based dentistry (EBD) that relates to occlusal therapy, selective occlusal adjustment (OA) and stabilization splints therapy (SS) for TMDs has had an unfavourable impact on the teaching of many of the important aspects of occlusion needed in dental practice. The teaching of OA systematically in dental schools has been nearly abandoned because of the belief that OA is an irreversible procedure and gives the impression that it is without merit elsewhere in the management of occlusion. However, a particular dose of knowledge and practice of occlusion that is necessary for all aspects of dental care should be taught systematically in dental schools. The uses and misuses of OA and SS and their limitations should be emphasized because of their importance to bring clinical reality into the dental curriculum. Thus, and irrespective of EBD induced contradictions, OA and SS should still have a significant place in systematically teaching of occlusal therapy. However, there are many more aspects of the management of occlusion that should to be considered. Hopefully, because of their importance, other aspects of the management of occlusion will once again become a significant part of the dental curriculum

PENINGKATAN KEMAMPUAN MEMBACA PEMAHAMAN MELALUI METODE WHOLE LANGUAGE (BAHASA UTUH) SISWA TUNANETRA KELAS IV SLB A YAKETUNIS YOGYAKARTA

Tujuan penelitian ini adalah meningkatkan kemampuan membaca pemahaman siswa tunanetra kelas 4 SLB A Yaketunis Yogyakarta dengan menggunakan metode whole language (bahasa utuh). Penelitian ini merupakan penelitian tindakan kelas (classroom action research) dengan desain yang terdiri dari perencanaan, tindakan, observasi, dan refleksi. Penelitian ini terdiri dari 2 siklus yang terdiri dari 3 pertemuan pada setiap siklusnya. Tindakan pada siklus 1 merupakan penerapan metode whole language dalam pembelajaran membaca pemahaman. Tindakan siklus 2 merupakan perbaikan dari tindakan siklus 1 karena belum tercapainya kriteria ketuntasan minimal sebesar 65%. Perbaikan tersebut dalam bentuk pemberian motivasi dan pancingan serta tips praktis untuk bisa menjawab pertanyaan. Pengumpulan data dilakukan dengan tes kemampuan membaca pemahaman, observasi, wawancara, dan dokumentasi. Analisis data menggunakan deskriptif kuantitatif dan penyajian data dalam bentuk tabel dan grafik histogram. Hasil penelitian menunjukkan bahwa metode whole language (bahasa utuh) dengan 2 siklus dapat meningkatkan kemampuan membaca pemahaman siswa tunanetra kelas 4 SLB A Yaketunis Yogyakarta. Pada siklus 1 skor pencapaian subjek 1 meningkat dari 56,52% menjadi 75,00%, subjek 2 meningkat 46,87% meningkat menjadi 62,50%, dan subjek 3 meningkat dari 43,75% menjadi 68,75%. Pada siklus 2 skor yang dicapai subjek 1 mencapai 84,37%, subjek 2 sebesar 68,75%, dan subjek 3 sebesar 78,12%. Peningkatan kemampuan membaca pemahaman dibuktikan dengan ketiga subjek sudah dapat menjawab pertanyaan bacaan, menemukan ide pokok dan kata kunci, serta dapat menceritakan kembali secara tepat dengan bahasa sendiri. Hasil tes pada siklus II menunjukkan bahwa semua siswa telah mencapai kriteria keberhasilan yang ditentukan yaitu sebesar 65%. Kata kunci: metode whole language, kemampuan membaca pemahaman, siswa tunanetr
