Perbedaan Jarak dan Sudut Dua Pertiga Wajah Bagian Atas pada Sefalometri dan Fotometri Lateral (Tinjauan pada Anak dengan Maturasi Vertebra Servikal Tahap Dua dan Tiga Ras Deutro Melayu) = Differences in Linear and Angular the Upper Two-Thirds of the Face in Cephalometry and Lateral Photometry (A Review of Children with Stage Two and Three of Cervical Vertebra Maturation in Deutro Malay Race)
" Latar Belakang : Sefalometri lateral merupakan pemeriksaan radiograf penunjang yang menjadi standar utama dalam mengetahui kelainan kompleks kraniofasial anak terutama pada kelainan pola skeletal serta menegakkan diagnosis dan penentuan rencana perawatan. Sefalometri memiliki efek paparan radiasi yang kumulatif dan dapat menginduksi kematian sel sehingga dapat merusak fungsi organ. Sekarang ini, terdapat pergeseran paradigma tujuan perawatan ortodontik yang lebih mengutamakan penilaian jaringan lunak. Fotometri lateral telah digunakan sebagai alat diagnostik non-invasif dan dapat memprediksi nilai keselarasan ... "

Color science and photometry for lighting with LEDs and semiconductor nanocrystals
" This book reviews the application of semiconductor nanocrystals also known as colloidal quantum dots (QDs) to LED lighting for indoors and outdoors as well as LED backlighting in displays, summarizing the color science of QDs for lighting and displays and presenting recent developments in QD-integrated LEDs and display research. By employing QDs in color-conversion LEDs, it is possible to simultaneously accomplish successful color rendition of the illuminated objects and a good spectral overlap between ... "

Circadian lighting design in the LED era
" This book explores how lighting systems based on LED sources have the ability to positively influence the human circadian system, with benefits for health and well-being. The opening chapters examine the functioning of the human circadian system, its response to artificial lighting, potential health impacts of different types of light exposure, and current standards in circadian photometry. A first case study analyzes the natural lighting available in an urban interior, concluding that it is unable ... "
