Sistesis aliran ekuivalen tree dengan menggunakan algoritma gomary - hu

ABSTRAK Suatu jaringan komunikasi tak berarah G(V, E, c, f) merupakan suatu jaringan komunikasi dengan himpunan titik V, himpunan garis E, fungsi kapasitas c dan fungsi aliran f. Dalam jaringan komunikasi ini, medium antar dua station yang dalam hal ini digambarkan sebagai garis mempunyai kapasitas yang disebut sebagai kapasitas garis. Dad kapasitas garis ini dapat ditentukan kapasitas terminalnya. Setiap jaringan komunikasi tak berarah -n-titik adalah ekuivalen terhadap tree dan terdapat paling banyak n - 1 bilangan kapasitas terminal yang berbeda. Algoritma Gomory - Hu membangun jaringan yang ekuivalen terhadap tree dengan menyelesaikan secara tepat masalah aliran maksimum n - 9. Masalah aliran maksimum ini diselesaikan daiam suatu jaringan yang lebih sederhana daripada jaringan asli

Determinants of healthcare utilisation and predictors of outcome in colorectal cancer patients from Northern Iran

We aimed to assess healthcare utilisation (HU), its determinants, as well as its relationship with survival in colorectal cancer (CRC) patients. This study was conducted on incident CRC cases from Northern Iran. Information on HU was collected using a valid questionnaire, considering eight diagnostic and four therapeutic services. The results were categorised as good and poor HU. Multivariate logistic regression analysis was used to assess the relationship between HU and other variables. Cox regression analysis was performed to determine major predictors of survival. In total, 227 new cases of CRC were enrolled. HU could be assessed in 218 subjects (96). Living in rural areas was the strongest variable related to poor HU (adjusted OR, odds ratio=2.65; CI, confidence interval: 1.30-5.40). The median survival time was 40.5months. The 1-, 3- and 5-year survival rates were 71, 52 and 44 respectively. Cox regression analysis showed a significant lower survival rate in patients with poor HU (HR=2.3; CI: 1.46-3.64). HU was an independent predictor of survival in our CRC patients. Patients' place of residence was a significant determinant of HU. Regarding its effects on patients' outcome, HU and its determinants should be considered in designing CRC controlling programmes in our region and similar high-risk populations. © 2016 John Wiley & Sons Ltd

The Making of a Movement: The Archival Reconstruction of Chicanismo in Northern New Mexico

The recovery of a movement is explored in this project inspired by the New Mexico Highlands University (HU) Archives and Special Collections. Known for its liberal student body in the 1960s and 1970s, I argue that HU was a catalyst for the Chicano Movement in northern New Mexico. The movement was punctuated by an influx of visitations by prominent activists such as Reies Lopez Tijerina and Rudolfo “Corky” Gonzales. Campus life at HU shifted from an Anglo-centric atmosphere to fostering a cultural space fueled by the Spanish language and the overt accusations of racism against minority students. Through my work, I show how Anglo and Chicano students confided in their school newspaper to express personal opinions and engage in racially charged correspondences across both groups. These conversations ignited a Chicano-student-based effort to elect the first Nuevomexicano and Chicano president of HU. These protests necessitated the involvement of the HU Board of Regents, whose readiness to elect a university president under such stipulations oscillated over the course of a year. Their responses to Chicano students are recorded in the HU Archives. I assert that the contrast of dialogues produced from the administrative entity and Chicano students reveals the latent racial tensions present on the HU campus. Finally, I demonstrate the manifestation of Mexican-American identity by investigating its historical contexts in New Mexico and its implications through a national lens. Post-Vietnam War sentiments speckle the racial commentary of students’ published works through art, poetry, and articles published in Spanish. By investigating primary, non-fictional sources, I work to reconstruct an historical movement and weave social commentary within a politically infused undertaking of exploring identity

Effect of antimicrobial use on the resistance of Escherichia coli in faecal flora of pigs

The antimicrobial use in veterinary medicine is of concern because of possible transmisston of resistant bacteria to humans. However the relation between use and occurrence of resistance is poorly documented in the field. Sixteen farrow-to-fimsh herds were selected and classified on the frequency of antimicrobial administrations (low (LU), medium (MU) and high (HU) users). lndtcative Eschenchia coli strains were tsolated from faeces of sows (5 per herd) and young pigs (3 per sow) at several ttmes during animals\u27 hfe and tested for reststance to amoxicillin, gentamicin, trimethoprim-sulfamids and tetracyclin. The percentages of resistant strams were compared between herd groups
