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: A Study of Supportive Treatment Used in Canine Parvovirus at ‘Animal Republic’ Veterinary Clinic, Ipoh, Malaysia in 2021
Abstrak: Canine parvovirus first emerged in the 1970s in dogs in Australia where it appeared very similar but perhaps slightly worse than the disease seen in the cat and has rapidly become the primary cause of severe illness and death for puppies and adolescent dogs. This study aims to analyze secondary data of supportive treatments, find out the most susceptible age for canine parvovirus and to understand how various supportive treatments of canine parvovirus help the recovery process. The study was done by collecting data from ‘animal republic’ veterinary clinic in 2021. The data was analyzed in excel and the most susceptible age group for canine parvovirus was determined. In conclusion, Puppies of 2-4 months are most severely affected by Canine Parvovirus-2. Antiemetics help reduce fluid loss. Antibiotics help counter sepsis due to destruction of gastrointestinal lining and fluid therapy help restore hydration levels to the body.

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.
