Judul: The Occurrence Of Canine Parvovirus On Dog In Segar Veterinary Hospital Kuala Lumpur, Malaysia From January To April 2022
Abstrak: Canine parvovirus (CPV) merupakan penyakit sangat menular dan menyebar dari anjing ke anjing melalui kontak langsung atau tidak langsung dengan kotorannya. Vaksin dapatmencegah infeksi ini, tetapi kematian dapat mencapai 91% pada kasus yang tidak diobati. Tujuan penelitian ini adalah untuk mempelajari prevalensi atau frekuensi kejadian dan persentase canine parvovirus di Rumah Sakit Hewan Segar, Kuala Lumpur Malaysia. Setiap canine parvovirus yang disajikan dan dicatat satu per satu antara bulan Januari hingga April 2022. Data kasus canine parvovirus pada anjing dikumpulkan dari rekam medik di Segar Veterinary Hospital Kuala Lumpur. Berdasarkan data primer penyakit menular anjingselama Januari- April menunjukkan ada 23 kasus penyakit menular anjing. Kasus canine parvovirus memiliki insiden tertinggi (7/23; 30,4%) dibandingkan dengan penyakit menular anjing lainnya seperti leptospirosis, rabies. Selama penelitian ini, tercatat bahwa jumlah anjing(3/7; 42,8%) yang tidak divaksinasi yang terinfeksi parvovirus anjing dan dirawat di rumah sakit dipulangkan, dengan sisa anjing (4/7; 57,2 %) yang terlambat masuk dan mati karena pengobatan yang tidak berhasil. Hal ini menunjukkan bahwa persentase keberhasilan pengobatan anjing yang tidak divaksinasi terinfeksi parvovirus anjing rendah. Persentase keberhasilan pengobatan dapat lebih tinggi jika didiagnosis dan diobati sejak dini. Umumnya, karena gejalanya biasanya jelas dan terlihat, pengobatan dan pengendalian dini dapat dilakukan., Canine parvovirus (CPV) is highly contagious and is spread from dog to dog by director indirect contact with their faeces. Vaccines can prevent this infection, but mortality can reach 91% in untreated cases. The objective is to study the occurrence of canine parvovirus at Segar Veterinary Hospital in Kuala Lumpur, Malaysia. The data of canine parvovirus cases on dogs will be collected from medical records in Segar Veterinary Hospital Kuala Lumpur. Each canine parvovirus which are presented and recorded individually between the month of January to April 2022. According to primary data collected of canine infectious diseases during January-April showed there were 23 cases canine infectious diseases. The canine parvovirus cases had the highest incidence (7/23; 30.4 %) compared to other canine infectious diseases such as leptospirosis, rabies. During this research, it is noted that the number of dogs(3/7; 42.8%) which are unvaccinated that are infected with canine parvovirus and being admitted to the hospital are discharged, with the rest of the dogs (4/7; 57.2%) that are admittedtoo late and deceased due to unsuccessful treatment. Therefore, this proves that the percentageof successful treatment of unvaccinated dogs infected with canine parvovirus is low. Usually,the percentage of successful treatment can be higher if diagnosed and treated early. Generally,as the symptoms are usually obvious and noticeable, early treatment and control can be done.

Judul: Kejadian Penyakit Distemper dan Parvo pada Anjing Melalui Pendekatan Klinis, Studi di Rumah Sakit Hewan Institut Pertanian Bogor
Abstrak: Dog’s viral diseases, such as Distemper and Parvo have a high morbidity and mortality rate. There is no cure, the treatment is only based on the clinical signs which veterinarian could see. Vaccination is the only way to prevent these viral diseases. Based on Animal Hospital Bogor Agricultural University’s data, in Parvo case, pure breed dogs have a higher incidence rate than local and mix breed dogs. Then the age of infected dogs under 1 year with the highest incidence rate at age 3-6 months, whereas the male gender has a higher incidence rate than female. For the case of Distemper, mix breed dogs have a higher incidence rate compared with pure breed dogs. Age of Distemper infected dogs are varied between 2 months to 1 year and there is no gender specific has the higher-level events. Study which is conducted at Animal Hospital Bogor Agricultural University to obtain secondary data of the Distemper and Parvo suspects, as comparison to another secondary data of Bogor’s climate. Changes of rainfall amount as one of weather elements can indirectly affect the incidence of disease Parvo and Distemper, but has no specific pattern. This is seen in both Parvo and Distemper cases, but the number of Parvo cases more than Distemper because CPV is more resistant due to the environment and easily mutate.

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.
