1. Herbicides applied in pre and post-emergence to control Chamaesyce hirta
ABSTRACT In view of the increase in the infested areas and the difficulty in controlling Chamaesyce hirta (L.) Millsp (garden spurge) there is growing interest in identifying herbicides that can be applied in pre and post-emergence, helping to reduce infestation and to provide species control. The objective of this work was to evaluate efficient alternatives

2. Hemorrhagic Versus Ischemic Risk in Patients with Atrial Fibrillation on Hemodialysis
Abstract Background Hemodialysis (HD) patients with atrial fibrillation (AF) have a particularly high risk of stroke and bleeding, but no high-quality evidence-based recommendations exist to properly manage these patients. Objectives We aim to evaluate the ischemic versus the hemorrhagic risk in a HD population with AF. Methods We selected incident pat

3. Immunohistochemical and clinicopathologic features of estrogen receptor-negative, progesterone receptor-positive, HER-2 negative breast carcinomas
SUMMARY OBJECTIVE: Currently, there is an ongoing debate whether progesterone receptor positive and estrogen receptor negative breast carcinomas represent a true distinct subtype of tumor or a mere immunohistochemical artifact. In this study, we conducted an immunohistochemistry panel with the antibodies TFF1, EGFR, and CK5 to reclassify this phenotype in a

4. A new device to autonomously feed individualized mantids on extended periods of time
ABSTRACT Mantises can live for many months, are naturally voracious, and feed invariably on live prey. Many species have a propensity for cannibalism and cannot be kept together for most of their life cycle, which makes large-scale rearing typically time-consuming, thus easily becoming prohibitive. This is particularly true for early instars, because they ar

5. HUME SOBRE A MÁXIMA CAUSAL: CONCEPTIBILIDADE E POSSIBILIDADE
RESUMO Uma das críticas mais contundentes ao argumento de Hume contrário ao status a priori ou logicamente verdadeiro da máxima causal - a de que todo evento deve ter uma causa - é a de Anscombe. Ela critica a passagem de Hume da contingência das associações causais particulares - que este evento deva ter esta causa - para a contingência de qualquer

6. Indirect estimation of infant mortality in small areas*
Resumo Métodos indiretos do tipo Brass para estimar a mortalidade nas primeiras idades da vida têm sido usados por mais de quatro décadas, fornecendo estimativas muito robustas para países que não possuem sistemas confiáveis de estatísticas vitais. No entanto, quando as áreas de estimativa são pequenas, o número de crianças mortas pode ser muito b

7. IS-LM: uma história?
RESUMO Para alguns economistas, o modelo IS-LM já passou, correspondendo a uma fase remota da história do pensamento econômico. Neste artigo, tentamos demonstrar que isso não é necessariamente verdade. Ao mesmo tempo, aproveitamos a longevidade do modelo para fornecer uma breve descrição de alguns eventos em Macroeconomia. Além disso, chamamos a aten

8. Histometry Analysis of Osteoclasts, Osteoblasts and Fibroblasts in Immediate Placement Implants with Addition of Aloe Vera Extract
Abstract Objective: To analyze the effect of immediate placement of implants with extract from the new bone formation histometically. Material and Methods: In this true-experimental design with randomized post test control group, 9 mongrel dogs weighing 10 to 12 kg were used, which were divided into 3 groups, based on observation time of 14 days, 28 days a

9. Implant-based factor as possible risk for peri-implantitis
Abstract Peri-implantitis is currently a topic of major interest in implantology. Considered one of the main reasons of late implant failure, there is an emerged concern whether implant characteristics could trigger inflammatory lesion and loss of supporting bone. The purpose of this narrative review is to provide an evidence based overview on the influence

10. Post-treatment of landfill leachate using rice husk ash as adsorbent medium
Resumo O aterro sanitário é o método mais geral de disposição de resíduos sólidos urbanos. Porém, no processo de degradação da matéria orgânica é produzido um líquido de coloração escura de alto potencial poluente sendo necessário tratamento adequado antes de seu lançamento nos corpos de água. Diversas tecnologias podem ser utilizadas no t

11. Neuroprotective Effect of Low Mean Arterial Pressure on Postoperative Cognitive Deficit Attenuated by Prolonged Coronary Artery Bypass Time: A Meta-Analysis
Abstract Introduction: The true influence of the low mean arterial pressure (low MAP) during coronary artery bypass grafting (CABG) on the development of postoperative cognitive deficit (POCD) remains controversial. We aimed to perform a meta-analysis and meta-regression to determine the effect of low MAP on POCD, as well as moderator variables between low

12. Influence of Crystallization and Ageing Time on the Reproducibility of Mesoporous Molecular Sieve SBA-15
ABSTRACT The study aimed to assess how the crystallization and ageing times in SBA-15 synthesis influence the reproducibility and particle size of mesoporous molecular sieves. X-ray diffraction showed that higher crystallization times provide greater reproducibility of mesoporous silica, due to the fact that there is no significant variation in the width and
