چکیده

Garcinia forbesii King adalah anggota genus Garcinia. Tanaman ini tanaman endemik pulau Sumatera dan Kalimantan di Indonesia. Uji aktivitas isolasi senyawa aktif sudah dilakukan oleh para peneliti diantaranya bagian pericarp dari G. terbukti memiliki kemampuan antioksidan, antiplasmodial antidiabetes secara invitro. Oleh karena itu untuk menjaga kualiatas bahan mentah diperlukan uji autentikasi. Metode yang dipergunakan dalam autentikasi menggunakan kemometrik dikombinasi spektrofotometri UV-vis, komposisi G.forbesii: G.mangostana; 0;15;45;55;80 100%.. Analisis data digunaka PLSR. Hasil diperoleh pada daerah lamda 248.92-224.66 nm model derivatisasi kedua RMSEC 4.79; R2 0,9901; RMSEP 5,01; R2;0,9909; RMSECV 12,6; 0,9308. Pada 292.37- 256.16 pertama 6,1; 0,9839; 6,19; 18,6; 0,8642. Kesimpulannya Lamda berkisar merupakan terbaik forbesii.

UV Melting of G-Quadruplexes.

Absorbance versus temperature curves can provide information on the thermal stability of DNA or RNA quadruplexes. Quadruplex denaturation or renaturation can be followed by recording absorbance at 295 nm rather than 260 nm, the wavelength used to monitor duplex denaturation. This unit describes the use of absorbance versus temperature curves to determine melting temperatures (T(m) values) and m...

G-Frames, g-orthonormal bases and g-Riesz bases

G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.
