Judul: Obat Terapeutik dalam Pengobatan Feline Lower Urinary Tract Disease (FLUTD) di Rumah Sakit Hewan Gasing, Malaysia
Abstrak: Feline lower urinary tract disease (FLUTD) is a broad term often used in describing any disorders affecting the lower urinary tract which includes the bladder and urethra. Although there are multiple causes of FLUTD, the common clinical signs seen are hematuria, stranguria, dysuria, pollakiuria, and periuria. The study aims to obtain and analyze secondary data of therapeutic drugs used in the treatment of FLUTD at Gasing Veterinary Hospital in the year 2019. The highest proportion of drugs used were antibiotics at 37%. Muscle relaxants were the second most administered drug at 34%, followed by anti-inflammatories at 26%. Other therapeutic substances which were administered in smaller proportions include anti-fibrinolytic agents (2%) and nutritional supplements (1%). It was concluded that, the types of drugs that were administered in FLUTD cases comprised of antibiotics, anti-inflammatories, muscle relaxants, anti-fibrinolytic agents, and nutritional supplements., Feline lower urinary tract disease (FLUTD) adalah istilah luas yang sering digunakan untuk gangguan pada saluran kemih dan uretra. Meskipun terdapat beberapa penyebab FLUTD, tanda klinis yang umum terlihat adalah hematuria, stranguria, disuria, pollakiuria, dan periuria. Penelitian ini bertujuan untuk mendapatkan dan menganalisis data sekunder obat terapeutik yang digunakan dalam pengobatan FLUTD di Rumah Sakit Hewan Gasing tahun 2019. Obat yang paling banyak digunakan adalah antibiotik dengan proporsi 37%. Obat relaksan otot adalah obat kedua yang paling banyak diberikan dengan proporsi 34%, diikuti oleh obat antiinflamasi (26%).

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
