Judul: Urolitiasis pada anjing
Abstrak: Urolitiasis adalah suatu penyakit dimana terjadi proses pengendapan batu pada traktus urinaria. Kalkuli yang paling banyak dijumpai pada kasus urolitiasis anjing adalah kalkuli magnesium amonium fosfat (struvite), jika dibandingkan dengan kalkuli oksalat, sistin dan urat (Osborne et al., 1982). Infeksi oleh Staphylococcus aureus pada traktus urinaria memgang peranan penting dalam proses pembentukan kalkuli, karena bakteri tersebut dapat menghasilkan enzim urease, raktor predisposisi tidak dapat dinisankan dari infeksi traktus urinaria. Pada anjing, tempat yang banyak didapati pengandapan kalkuli adalah kantung air kemih dan uretra, sedangkan pada ginjalnya jarang. Pada anjing jantan lebih sering kejadiannya dibanding dengan pada anjing betina, karena anatomi traktus urinaria pada anjing jantan lebih memungkinkan untuk terjadinya obstruksi, yaitu lebih panjang dan sempit. Besarnya, kalkuli bervariasi, dari kecil dan halus seperti pasir sampai besar dan kasar seperti batu karang. ...

Judul: Kasus urolitiasis pada anjing dan kucing
Abstrak: Tujuan studi kasus ini adalah untuk mengetahui banyaknya kejadian kasus urolitiasis pada anjing dan kucing. Data kasus diperoleh melalui data rekam medis Rumah Sakit Hewan Jakarta, Rumah Sakit Hewan IPB, dan Klinik PDHB 24 jam drh. Cucu Kartini S., dkk pada tahun 2007-2008. Hasil studi menunjukkan kasus urolitiasis meningkat di tahun 2008. Kasus pada jantan lebih banyak daripada betina. Begitu pula kasus pada anjing lebih banyak daripada kucing. Kejadian urolitiasis pada anjing paling banyak didapatkan pada anjing berumur 7 tahun dan jenis batu yang didapatkan adalah kalsium oksalat 42%, struvite 33% dan sisanya adalah silica 17% serta cystine 8%. Ras anjing yang mendominasi adalah Pomeranian dan ras campuran. Ras kucing yang mendominasi adalah ras Persia dan paling banyak terjadi pada umur 5 tahun. Berdasarkan permeriksaan laboratorium dari enam buah sampel, diketahui bahwa masing-masing batu memiliki penampilan fisik yang berbeda serta tersusun dari banyak jenis kristal.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
