A paixão pela Arte Moderna e Contemporânea nasce da conveniência com vários autores e colecionadores. Perante tal situação, chegou a fase da comercialização.

Objetivou-se, com este trabalho, avaliar a possibilidade de aplicação do pendimethalin à casca de arroz e à serragem para o controle de plantas daninhas em Ixora chinensis. Dois experimentos foram conduzidos aplicando-se o pendimethalin às coberturas mortas através de embebição e pulverização do herbicida, variando-se também a quantidade de cobertura utilizada. As espécies de plantas daninhas que ocorreram com maior frequência foram Alternanthera tenella, Blainvillea rhomboidea, Cenchrus echinatus e Commelina benghalensis. Há possibilidade de aplicação do herbicida pendimethalin à palha de arroz ou à serragem para controle de plantas daninhas em I. chinensis, principalmente quando ocorrem chuvas regulares e bem distribuídas. Há evidências de que a embebição da cobertura morta no herbicida seja um pouco mais eficiente no controle das plantas daninhas que a sua pulverização sobre a cobertura. Possivelmente, a quantidade de cobertura morta utilizada influencia na eficiência de controle, apesar deste fato não ter ficado claro neste trabalho.

OCD was once thought to be uncommon, but since 1980, epidemiologic studies have revealed lifetime prevalence rates ranging from 1.9% to 4% in community samples, both in adults and adolescents. Moreover, studies examining case series of patients with OCD have found that the majority have an age of onset before 18 years. Described as a "hidden epidemic" in the past, OCD is the fourth most common psychiatric disorder and is receiving more public recognition (consider Hollywood's portrayal of a man with OCD in the movie "As Good As It Gets"). The increased public visibility of OCD has paralleled the emergence of effective treatments-both psychotherapeutic: for the most part the use of a cognitive-behavioral approach and also a pharmacologic one, primarily utilizing SSRI agents. We will review current pharmacologic agents available for OCD in children and adolescents. First-line agents, such as selective serotonin reuptake inhibitors (SSRI) and serotonin reuptake inhibitors (SRI)-as well as augmenting and alternative agents-will be discussed. FDA-Approved Agents for OCD Four pharmacologic agents have undergone extensive, multicenter, double-blind placebo controlled trials demonstrating safety and efficacy. These agents are currently FDA-approved for the treatment of OCD in children and adolescents. The four drugs include: clomipramine (Anafranil), fluvoxamine (Luvox), paroxetine (Paxil) and sertraline (Zoloft). Clomipramine is a non-selective serotonin reuptake inhibitor (SRI), and fluvoxamine, paroxetine, and sertraline are selective serotonin reuptake inhibitors (SSRI). Other SSRIs also used in the treatment of OCD include fluoxetine (Prozac) and citalopram (Celexa). There are no head-to-head comparison studies between any of the five SSRI agents on the market, and clinical experience shows that all are effective in treating OCD in children and adolescents. Clomipramine use is accompanied by a greater incidence of side effects. In children and adolescents, agent selection in the treatment of OCD should therefore be based on side effect and metabolism (cytochrome-P450, CYP-450) profiles, as well as more practical consideration such as types of preparations available.
