Judul: Studi Kasus Penyakit Periodontal Pada Anjing Yorkshire Terrier Dengan Alat Diagnosa Radiografi Serta Penanganannya
Abstrak: Penyakit periodontal merupakan penyakit yang sering terjadi pada anjing. Penanganan penyakit periodontal dapat dilakukan dengan teknik operasi dibantu dengan alat diagnosa radiografi. Tujuan studi kasus ini adalah mengetahui gambaran radiografi serta penanganan kasus penyakit periodontal pada anjing Yorkshire Terrier. Penanganan penyakit periodontal dilakukan dengan pemeriksaan keadaan gigi anjing yang hasilnya dicatat ke diagram gigi anjing terlebih dahulu. Radiografi dilakukan dengan menggunakan teknik paralel pada gigi premolar dan molar mandibula anjing. Hasil pengambilan gambar radiografi menunjukan adanya penurunan densitas pada sekitar gigi molar 308 yang memiliki nilai indeks plak, gingivitis, dan furcation yang tinggi dibandingkan dengan gigi yang memiliki nilai indeks yang kecil yaitu gigi 306. Selain itu, pada gigi 308 didapatkan sulkus gingiva sedalam 0.3 mm. Pencabutan gigi anjing dilakukan pada seluruh gigi incisor mandibula. Berdasarkan studi kasus yang dilakukan, diagnosa untuk melakukan penanganan penyakit periodontal dapat dilakukan dengan radiografi. Selain indeks plak, gingivitis, dan furcation pencabutan gigi dilakukan dengan melihat mobilitas gigi.

Judul: Studi Kasus Kelainan Regio Abdomen Anjing Melalui Interpretasi Radiografi di Klinik Hewan MyVets Kemang dan Bumi Serpong Damai
Abstrak: The aim of this study was to analyze abnormality and disease in abdomen region of dog by radiographic interpretation. The study was done by radiographic interpretation and confirmed with medical record that was taken from MyVets Animal Clinic Kemang and Bumi Serpong Damai. Interpretation was done by seven of basic Roentgen signs with changes of size, shape, number, location, margination, opacity, and alteration of organ function. Interpretation result was grouped by three system organ which are gastrointestinal, urinary, and reproduction system. Nine cases were taken for further discussion and compared it with literature. Abnormalities that were found in gastrointestinal system are constipation with prolaps ani, gastric foreign body, and bloating. Abnormalities that were found in urinary system are urolithiasis in urethra, renal failure, and nephromegaly with urolithiasis. Abnormalities that were found in reproduction system are dystocia fetalis, mummification, and pyometra.

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.
