Estudo do método Monte Carlo e sua aplicação no modelo SIR

In this work we present a discussion and the results of the simulation of disease spread using the Monte Carlo method. The dissemination model is the SIR model and presents as main characteristic the disease evolution among individuals of the population subdivided into three groups: susceptible (S), infected (I) and recovered (R). The technique used is based on the introduction of transition probabilities S-> I and I->R to do the spread of the disease, they are governed by a Poisson distribution. The simulation of the spread of disease was based on the randomness introduced, taking into account two basic parameters of the model, the power of infection and average time of the disease. Considering appropriate values of these parameters, the results are presented graphically and analysis of these results gives information on a group of individuals react to the changes of these parameters and what are the chances of a disease becoming a pandemic

Influência do volume reduzido e do estádio fenológico da planta de soja no controle da Anticarsia gemmatalis (Hübner, 1818)

Pós-graduação em Agronomia (Entomologia Agrícola) - FCAV

Potencial do controle biológico para o controle de Pseudoplusia includens (Walker, 1857) e Anticarsia gemmatalis Hubner, 1818 (Lepidoptera: Noctuidae) em soja

The soybean (Glycine max) is of great importance to national economic scenario being a major Brazilian agribusiness products. In most regions, the caterpillar-of-soy (Anticarsia gemmatalis) and caterpillar-false-Medideira (Pseudoplusia includes), act as defoliators, with the highest incidence, usually during the growing season, until the end of flowering, and thus causing a significant reduction in the production, which requires control measures. Due to market demands and the large external environmental awareness exists today, the methods of ecological management have been highlighted in modern agriculture. The use of chemical insecticides, besides being harmful to the environment and man, is, in most cases, the high cost to the farmer. The biological pest control using natural enemies can be used as an alternative control method. Thus this literature review is intended to provide the updated information about these pests and biological control as an alternative form of control, as well as one more tool in the integrated pest of soybean.

Samuel Avon Smith Diary- Accession 284 - M121 (154)

The Samuel Avon Smith Diary is a journal written Samuel Avon Smith who was a Confederate soldier during the American Civil War (Company H, 5th Regiment, SC) and a doctor. The journal was written from ca. 1830-1876 or beyond (some pages have been destroyed). The first part is a reminiscence of his life from 1830 to ca. 1873 and from that point on he gives a monthly account of life in Bullock’s Creek, SC. Subjects covered in the journal are the battles of Manassas and Seven Pines, Confederate Troops at Leesburg, the reorganization of the Confederate Army, the march to Richmond, the conditions of the troops, wounds received at the battle of Seven Pines and his medical treatment at the Confederate hospital in Manchester, Virginia, his education at the Ebenezer Academy and the Medical College of SC in Charleston; his life, practice, and health conditions in Gaston County, NC, Lincoln County, NC, and in Bullock’s Creek, SC; and sentiments towards the reconstruction government and Ku Klux Klan. There is also mention of a conflict between Blacks and Whites in Chester County, SC in 1871.

Alexander Samuel Salley Letters - Accession 45 - M20 (30)

The Alexander Samuel Salley Letters consist of a 1930 letter concerning Salley’s comments on the exchange between South and North Carolina of two strips of land that led to the King’s Mountain becoming a part of South Carolina in 1772, eight years before the battle and a 1921 letter in which Salley addresses various historical songs of South Carolina and his reputation as an historian.

Morphological structure of the liver in tambaqui, Colossoma macropomum (Cuvier, 1818)

This research aimed to describe the macroscopic and microscopic liver of tambaqui, Colossoma macropomum, Teleost freshwater Family Characidae, of great economic interest for the Amazon basin. We used six juveniles aged between six month and one year, from the small holding Esteio, Alta Floresta/MT, that develops mainly fish farming. The body was photographed in situ, described macroscopically, and fragments were removed and processed by routine histological techniques through paraffin embedding and HE staining. The liver, located ventrally to the swim bladder and craniodorsally to the stomach, is brownish red and consisted of three lobes, the right lateral, the left lateral and the ventral lobe. Microscopically, the parenchyma consists of hepatocytes varying from irregular rounded hexagonal to round forms with a large and central nucleus, and arranged in linear strings limited by sinusoids and radiating to central veins, but with absence of liver lobules. The central veins are distributed throughout the parenchyma, while the portal space consists in most cases only of a hepatic vein and bile duct; elsewhere exist artery and duct. Formation of portal triads was not founde. Melano macrophages were frequently seen dispersed throughout the central parenchyma. The morphofunctional study of the digestive system of fishes of the Amazon basin is important to obtain knowledge about their weight gain, large scale production for human consumption and preservation of the species, and has also its importance for being used as bioindicators today.

Negativi di memoria. La rappresentazione del trauma nel romanzo del Novecento. Samuel Beckett, Georges Perec, Agota Kristof

Oggetto di questa tesi è l’analisi delle modalità di rappresentazione del trauma nel romanzo del Novecento e, in particolare, nelle opere di Samuel Beckett, Georges Perec e Agota Kristof. Fondamento dello studio sarà una disamina dei procedimenti linguistici e narrativi di rappresentazione del trauma nelle prose degli autori citati, al fine tracciare le linee di un’estetica in grado di descrivere le caratteristiche peculiari delle narrazioni in cui la dimensione antinarrativa della memoria traumatica assume il ruolo di principio estetico guida. L’analisi si soffermerà sulla cruciale relazione esistente, in tutti e tre gli autori, tra rappresentazione del trauma e sviluppo di strategie narrativi definibili come “denegative”. L’analisi dei testi letterari è condotta sulla base del corpus critico dei Trauma Studies, dell’ermeneutica della narrazione di stampo ricœuriano e della teoria del linguaggio psicoanalitica e affiancata, ove possibile, da uno studio filologico-genetico dei materiali d’autore. Alla luce di tali premesse, intendo rivalutare il carattere rappresentativo e testimoniale della letteratura del secolo scorso, in contrasto con la consuetudine a vedere nel romanzo novecentesco il trionfo dell’antimimesi e il declino del racconto. Dal momento che le narrazioni traumatiche si costruiscono intorno e attraverso i vuoti di linguaggio, la tesi è che siano proprio questi vuoti linguistici e narrativi (amnesie, acronie, afasie, lapsus, omissioni e mancanze ancora più sofisticate come nel caso di Perec) a rappresentare, in modo mimetico, la realtà apparentemente inaccessibile del trauma. Si tenterà di dimostrare come questi nuovi canoni di rappresentazione non denuncino l’impossibilità del racconto, bensì una sfida al silenzio, celata in più sottili e complesse convenzioni narrative, le quali mantengono un rapporto di filiazione indiretto − per una via che potremmo definire denegativa − con quelle del romanzo tradizionale.
