Judul: Radiographic views of fracture in horse proximal sesamoid bone
Abstrak: Radiography is commonly use in veterinary medical purpose to help in diagnose abnormalities of animal organs and bones. This study aims to find and evaluate the fracture of proximal sesamoid bone in horse by digital radiography. The local horse named Belang was found with blindness and severe lameness. Physical examination result and clinical signs were written on the medical report. Radiography imaging was carried out on the left forelimb with a lateromedial and dorsopalmar point of view then used with digital radiography. Radiopaque lesions were obviously found surrounds the proximal sesamoid bone, on craniodistal third metacarpal bone, caudoproximal second phalanx bone and a little bit change of navicular bone in lateromedial view of the radiographic result. Fracture lesion on laterodistal of third metacarpal bone and radiopaque lesion still found around the proximal sesamoid bone in dorsopalmar view. Presence of callus is the sign of proximal sesamoid bone fracture., DESY ERIANTI. Gambaran Radiografi Kasus Fraktur Os Sesamoid pada Kuda. Dibimbing oleh BUDHY JASA WIDYANANTA dan DEWI RATIH. Radiografi umum digunakan dalam dunia kedokteran hewan sebagai alat menunjang diagnosa terhadap kelainan pada pertulangan maupun organ hewan. Penelitian ini bertujuan untuk mempelajari kasus fraktur os sesamoid proksimal pada kuda menggunakan radiografi digital. Seekor kuda betina lokal bernama Belang memiliki anamnesa kebutaan dan kepincangan yang parah. Hasil pemeriksaan fisik dan tanda klinis dicatat pada lembar rekam medik. Gambaran radiografi digital diambil pada kaki kiri depan kuda Belang menggunakan standar pandang lateromedial dan dorsopalmar. Lesi radiopak tampak jelas ditemukan di sekitar os sesamoid proksimal, craniodistal dari os metacarpal III, caudoproximal dari os phalanx II, perubahan sudut hoof dan perubahan os navicular (os sesamoid proksimal) pada standar pandang lateromedial. Lesi fraktur pada laterodistal os metacarpal III dan lesi radiopak masih ditemukan di sekitar os sesamoid proksimal pada standar pandang dorsopalmar. Kalus yang teridentifikasi menunjukkan os sesamoid proksimal mengalami fraktur.

Judul: Interpretasi Radiografi Regio Fetlock dan Pemeriksaan Fisik Kuda Warmblood di Direktorat Polisi Satwa.
Abstrak: Kuda memiliki kecerdasan yang dapat dimanfaatkan salah satunya sebagai hewan penunjang dalam patroli. Kegiatan kuda patroli meningkatkan risiko terjadinya cedera pada persendian fetlock. Penelitian ini bertujuan untuk menginterpretasikan radiografi pada regio fetlock kaki depan kuda warmblood di Direktorat Polisi Satwa. Pengamatan ini menggunakan 6 ekor kuda partoli. Pengambilan gambar radiografi dilakukan dengan posisi dorsopalmar, lateral, dan oblique. Berdasarkan posisi pengambilan radiografi terlihat tulang sesamoid proximal, os. metacarpal II, os. metacarpal III, os. metacarpal IV, dan phalanx proximal tidak mengalami perubahan dari segi bentuk, jumlah, lokasi, ukuran, marginasi, dan opasitas. Hasil pemeriksaan klinis menunjukkan kelainan sebanyak 1 kuda (16.67%) pada saat walk, 2 kuda (33.33%) pada saat trot, 2 kuda (33.33%) pada saat lungeing, 1 kuda (16.67%) pada saat fleksi pasif, dan 2 kuda (33.33%) pada saat fleksi aktif. Hasil pemeriksaan fisik menunjukkan adanya kelainan cara berjalan pada beberapa kuda, namun hasil evaluasi radiografi pada posisi dorsopalmar, lateromedial, dan oblique menunjukkan tidak adanya kelainan.

Abstrak: Planetary Boundary Layer is the lowest part of the atmosphere directly affected by the earth’s surface and responds to surface forcings within a time period of hourly to daily. The thickness of boundary layer varies over space and time, ranging from hundreds of meters to a few kilometers. The objective of this study consist of the analysis of Boundary Layer based on diurnal and nocturnal vertical profiles of meteorological properties and identification of characteristics pertaining to tropical atmosphere (represented by Soekarno-Hatta (6.110S, 106.650E), Polonia (3.560N, 98.680E), and Da Nang (16.030N, 108.200E) stations) and subtropical atmosphere (represented by Perth (31.930S, 115.960E), Nanjing (32.000N, 118.800E), and Hakasskaja (43.780N, 87.620E) stations). Virtual potential temperature, specific humidity, wind speed and direction, atmospheric stability, and Bulk-Richardson number are used to estimate the boundary layer thickness. Vertical profile of the virtual potential temperature and specific humidity are used to determine the Mixed Layer heights during the day and Residual Layer heights during the night. On the other hand, the mean value of Turbulent Flow Thickness is derived from the vertical profile of the Bulk-Richardson number (RiB). Analytical results of this study revealed that Mixed Layer height in the tropical atmosphere varies in a range from 260 m to 1410 m, Residual Layer height varies in a range from 267 m to 925 m, whereas the Turbulent Flow Thickness variation is confined between 0 m to 335 m. In subtropical atmosphere Mixed Layer height varies in a range from 101 m to 1483 m, Residual Layer height varies in a range from 121 m to 1276 m, whereas the Turbulent Flow Thickness variation is confined between 0 m to 769 m. This study also revealed that, except during summer, Mixed Layer Heights in the tropics are normally higher than in the subtropics.
