Judul: Kajian Mikroskopis Induksi N-Methyl-N-Nitrosourea Pada Kelenjar Mammari Kelinci
Abstrak: The aim of this research is to study the N-Methyl-N-Nitrosourea (MNU) induction on the rabbit’s mammary gland tumour formation. Six 6-9 month old, female rabbit were induced by N-Methyl-N-Nitrosourea (MNU) intramammary dose 50 μg/kg Body Weight, every 1 weeks for 4 week. After 4 weeks of induction, mastectomy were done. The mammary glands were processed for histopathological examination stained with HE. One lactating rabbit was act as normal mammary control. The result showed that the N-Methyl-N-Nitrosourea (MNU) could induced tumorigenesis which characterized as benign and slow growth tumor, as well as the inflammatory reaction.

Judul: The Effect of Ethanol Extract of Curcuma Zedoaria Rhizome on Clinical Signs in Rabbit during the formed process of Mammary Neoplasm which Induced by Methyl-N-Nitrosourea
Abstrak: DATA PUTRA S. B04050439. The Effect of Ethanol Extract of Curcuma Zedoaria Rhizome on Clinical Signs in Rabbit during the formed process of Mammary Neoplasm which Induced by Methyl-N-Nitrosourea. Under Recommendation of GUNANTI and RINI MADYASTUTI. The aim of this research was to determine the effect of ethanol extract Curcuma zedoaria on clinical signs in rabbit (Oryctolagus cuniculus) during the formed process of mammary neoplasm which induced by Methyl-N-Nitrosourea. Nine rabbits were divided into three groups. First group was untreated which used as control group and also not Induced by Methyl-N-Nitrosourea, the second group was positive control which induced by Methyl-N-Nitrosourea 50 mikrogram/kg BW and gave curcumin 60 mg/kg BW treatment, the third group was induced by Methyl-N-Nitrosourea and treated with extract ethanol of Curcuma zedoaria rhizome 250 mg/kg BW each rabbit. The result showed that extract ethanol can keep the body temperature 39.23±0.59, heart rate 133±8.22 still in normal range in rabbit which induced by Methyl-N-Nitrosourea and given extract ethanol of Curcuma zedoaria rhizome and curcumin Key words : Curcuma zedoaria, Extract, Rabbit, Clinical Signs, Methyl-N-Nitrosourea

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
