Drying colloidal systems: laboratory models for a wide range of applications

The drying of complex fluids provides a powerful insight into phenomena that take place on time and length scales not normally accessible. An important feature of complex fluids, colloidal dispersions and polymer solutions is their high sensitivity to weak external actions. Thus, the drying of complex fluids involves a large number of physical and chemical processes. The scope of this review is the capacity to tune such systems to reproduce and explore specific properties in a physics laboratory. A wide variety of systems are presented, ranging from functional coatings, food science, cosmetology, medical diagnostics and forensics to geophysics and art

Peningkatan Taraf Kesehatan Gigi dan Mulut Komunitas Sekolah Dasar dan Masyarakat Kelurahan Jatipulo Kecamatan Palmerah, Jakarta Barat

According to Riskesdas 2018 data, the prevalence of caries in Indonesia is 88.8%. Maintaining healthy teeth and mouth is very important because oral health is an integral part of body health which is interrelated with general health in our bodies. The community in the elementary school environment and the people of Petamburan Village, Jatipulo, West Jakarta, have a low economic level, where people prioritize meeting their daily basic needs compared to spending on maintenance and treatment of teeth and mouth. Through counseling and dental and oral health services, it will improve understanding and quality of dental and oral health in the school community and community in the jatipolo-West Jakarta district. About 90 primary school communities and 50 communities participated in this program. There were 86 people from 90 elementary school communities and 48 people from 50 people who received treatment in the form of filling and extractions. From the data obtained, around 99.95% of the total primary school community and the community have dental and oral health problems. Therefore it is necessary to provide ongoing assistance to improve the level of oral health in the Jatipulo area, West Jakart

Correlation between Osteoprotegerin Serum Levels and Arterial Stiffness Assessed by Cardio-ankle Vascular Index (CAVI) in Hypertensive Patients

Abstract The cardio-ankle vascular index (CAVI) is a newly developed clinical measurement for evaluating arterial stiffness from the origin of the aorta to the ankle. Osteoprotegerin (OPG) is widely known as a vascular calcification mediator, which have a role to affect atherogenesis. Thirty subjects participated in this research and each subject underwent a CAVI examination to assess arterial stiffness and their blood samples were collected for OPG measurement. This study is analyzed with Pearson Correlation Test. There is a positive, strong and significant correlation between osteoprotegerin serum level and arterial stiffness using Cardio-Ankle Vascular Index (CAVI) in hypertensive patients. (r = 0.730 and p <0,0001). There was a positive, strong and significant correlation between osteoprotegerin serum level and arterial stiffness using Cardio-Ankle Vascular Index (CAVI) in hypertensive patients

Analisis Motivasi Belajar Intrinsik pada Pembelajaran Matematika Kelas XI SMA Negeri 1 Kedungreja

Penelitian ini bertujuan untuk menganalis motivasi belajar intrinsik pada pembelajaran matematika siswa SMA Negeri 1 Kedungreja. Subjek pada penelitian ini adalah seorang guru matematika dan 20 siswa kelas XI-MIPA 4 SMA Negeri 1 Kedungreja. Deskriptif kualitatif adalah metode yang digunakan pada penelitian ini. Pengumpulan data dilakukan dengan kuesioner dan wawancara. Hasil penelitian menunjukkan bahwa terdapat 15 orang siswa dengan kategori motivasi belajar intrinsik tinggi dan 5 orang siswa berkategori sedang. Analisis rata-rata skor per indikator untuk kedua kategori motivasi belajar intrinsik menunjukkan bahwa semua indikator berada pada kategori tinggi baik motivasi tinggi maupun sedang. Namun selisih rata-rata skor yang paling tinggi di antara ketiga indikator lain adalah pada indikator kebiasaan baik dengan nilai selisih 0.81. Penghitungan tersebut juga terkonfirmasi melalui wawancara bahwa siswa bermotivasi belajar intrinsik tinggi akan mempelajari materi sebelumnya jika besok adalah jadwal pelajaran matematika, sedangkan siswa dengan kategori motivasi belajar intrinsik sedang menyatakan bahwa jika besok adalah jadwal pelajaran matematika mereka hanya melihat materi sebelumnya
