Tujuan dari penelitian ini untuk mengetahui efektivitas penambahan Zat Pengatur Tumbuh ( ZPT) pada pertumbuhan tunas dan perakaran stek mikro kulit umbi tanaman porang (Amorphophallus muelleri blume) talas beneng (Xanthosoma undipes k.koch). Rancangan Acak Lengkap (RAL) digunakan dalam dengan 8 perlakuan : Z1 = tanpa ZPT, Z2= + Auksin 1,5 ml/L, Z3= +Thidiazuron 1 ppm, Z4= +Auksin ml/L Th...

Vitamin D reaches the body from two totally dissimilar sources, first by cutaneous synthesis under the action of ultraviolet light and secondly in the diet. The relative contribution of these sources to human vitamin D nutrition is uncertain; this paper will examine some of the factors which determine their efficacy and the ultimate production of rickets. Our studies have also provided evidence...

This paper develops and implements a new algorithm for calculating wave trace invariants of a bounded plane domain around a periodic billiard orbit. The algorithm is based on a new expression for the localized wave trace as a special multiple oscillatory integral over the boundary, and on a Feynman diagrammatic analysis of the stationary phase expansion of the oscillatory integral. The algorith...

BACKGROUND Recently, the increased demand of energy has strongly stimulated the research on the conversion of lignocellulosic biomass into reducing sugars for the subsequent production, and β-glucosidases have been the focus because of their important roles in a variety fundamental biological processes and the synthesis of useful β-glucosides. Although the β-glucosidases of different sources ha...

Objectives: The use of a biomaterial scaffold can improve the healing process bone defects. Using radiologic and ultrasonographic methods, this study aimed to evaluate effects zeolite/collagen nanocomposite nanohydroxyapatite (nHA) scaffolds on defect in rabbit femur. Materials Methods: Twenty-eight mature male New Zealand white rabbits were classified into four equal groups (n=7 each). In firs...
