Judul: Uremia pada anjing
Abstrak: Uremia adalah suatu keadaan peningkatan kadar urea didalam plasma darah yang melebihi dari kadar normalnya. Sering juga digunakan sebagai istilah klinik 'clinical uraemia yang berarti menunjukkan gejala kompleks yang terlihat pada kasus kegagalan ginjal baik yang akut maupun kronis, sehingga terjadi retensi nitrogen. Urea merupakan senyawa nitrogen bukan protein yang di- sintesis oleh hati sebagai hasil dari katabolisme protein. Urea tersebut kebanyakan diekskresikan melalui air kemih dan hanya sedikit yang lewat tinja ataupun keringat. Kadar urea darah anjing normal berkisar antara 10-30 mg/100 ml darah. Namun pada kasus uremia yang parah kadar urea bisa meningkat sampai 500 mg/100 ml darah. Uremia ini sering terjadi pada anjing-anjing sudah berumur tua atau anjing yang mengalami gangguan pada ginjalnya. ...

Judul: Studi Kasus: Morfopatologi Anjing Penderita Ehrlichiosis yang Disertai Sindrom Uremia
Abstrak: Ehrlichiosis adalah penyakit infeksius dengan morbiditas tinggi yang disebabkan oleh Ehrlichia canis pada anjing. Di sini menjelaskan tentang morfopatologi anjing jenis German Sheperd dan Labrador retrivier yang menderita Ehrlichiosis disertai uremia yang dating ke Divisi Patologi, Departemen Klinik, Reproduksi, dan Patologi, IPB University. Anjing ditemukan mati dengan perdarahan hebat di seluruh subkutis dan berbagai organ, edema subkutis di semua tungkai, jaringan lidah nekrotik, dan mukosa pucat. Studi kasus ini bertujuan untuk mengkaji perubahan patologi-anatomi dan histopatologi dari berbagai organ anjing sehingga diketahui perjalanan penyakit dan penyebab kematiannya. Sampel organ kedua ekor anjing meliputi jantung, paru-paru, lidah, lambung, usus, hati, limpa, dan ginjal dibuat preparat histopatologi dan diwarnai dengan pewarnaan Haematoksilin-Eosin. Hasil pemeriksaan patologi-anatomi menunjukkan kedua ekor anjing mengalami perdarahan di berbagai organ, bentuk jantung double apex, hipertrofi ventrikel kiri, chicken fat clot di ventrikel kanan dan kardiomiopati, kongesti paru-paru dan bronkitis, stomatitis ulseratif, gastritis ulseratif, enteritis mukopurulenta, hati ikterus dan kongesti, splenitis dan nefritis interstisial kronis. Hasil pemeriksaan histopatologi paru-paru menunjukkan bronkheolitis dengan banyak koloni bakteri dan sel radang netrofil, serta nefritis interstitialis kronis dengan glomerulopati. Kardiomiopati menyebabkan kegagalan jantung yang berakibat kongesti pada seluruh organ. Kematian pada kedua ekor anjing ini disebabkan sepsis, kegagalan fungsi organ terutama jantung, hemoragik shok, dan uremia.

Judul: Algorithm construction of HLI hash function
Abstrak: Cryptography is a study of mathematical techniques related to aspects of information security regarding on confidentiality, data integrity, entity authentication, and data origin authentication. Data integrity is a service, which is associated with the conversion of data carried out by unauthorized parties. To maintain data integrity, one can use hash functions. An hash function is a computationally efficient function to map an arbitrary length bitstring to a fixed length bitstring called as hash value. The use of hash function in maintaining the information integrity and authentication is in digital signatures, virus protection, and software distribution. Illustration of the hash function in the integrity and authentication of information that is emailed as follow. The sender sends the information and hash value to the recipient. If the hash value of the information is equal to the hash value that is sent by the sender, then information has not been changed. Otherwise the information has been changed. An hash function has two properties, one way and collision resistance. An hash function is called one way if it is computationally infeasible to find any input such that when given any hash value . Meanwhile an hash function is called collision resistant if it is computationally infeasible to find any two inputs where such that . The purpose of this study is to construct a HLI hash function algorithm, to analyze the speed and security of the hash functions as a results of construction. Furthermore, it is to compare it with SWIFFT. Hash function is constructed based on the result of algebraic operations on modular polynomial ringwith . Modular polynomial ring noted as is a set of all polynomials of degree at most with coefficients in . can be represented as a set of integer vector of modulo in dimension . So, it is simple to implement in a computer. In vector operations, is lattice . Furthermore, alattice that is defined from certain polynomial ring is called ideal lattice. HLI hash function is consists of addition and multiplication algorithm in the ring. Addition algorithm consists of sumation operations of modulo and multiplication consists of multiplication operations of modulo . Generally, algorithm of HLI hash function consists of multiplication operations of modulo and addition operations of modulo . However, if the input is binary number then multiplication algorithm only consists of multiplication operation of modulo , so algorithm of HLI hash function consists of multiplication operations of modulo and addtion operations of modulo . An hash function is secured if it has two properties, i.e., one way and collision resistance. HLI hash function hash is one way, it is following the proof of Micciancio. It is has collision resistant because of polynomial is irreducible over and monic. Moreover, it is proved that for every unit vector , the vector is small vector. If the input of hash function is a binary number then HLI hash function only involves addition operations of modulo . So the time that used almost same with SWIFFT. The excellence of HLI hash function is the key size smaller than SWIFFT. This effect on
