It also sought to verify the magnitude of response of mechanical control compared to treatment without intervention, for similar sites where the experiment was installed and conducted. The treatments were: T1 - mechanical (mowing and crowning); T2 - chemical (application of glyphosate syrup); T3 - mechanical cultural (weeding, seeding and cultivation of Cajanus cajan and Canavalia ensiformes); T4 - chemical cultural (application of glyphosate, seeding and cultivation of legumes); T5 - absolute control (no intervention after planting). Activities and evaluations were carried out up to 30 months after planting the seedlings of the five species used. It was observed that in all treatments the survival of the plants reached values higher than 80%, at 6 and 18 months after planting. It was found that, on average, the tree plants in T2, T3, and T4 showed significantly higher growth than those in T1 and T5, which did not differ. The control with glyphosate is indicated for areas with predominance of Urochloa sp. Strategy control with glyphosate and cultivation of herbaceous legumes has potential use and needs adjustments to reduce costs. Also, that the control with mowing and crowning is not indicated due to the high cost and not favoring the growth of the planted trees, because it did not show significant differences in relation to the controls.","PeriodicalId":37865,"journal":{"name":"Fronteiras","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42113155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic procedure for searching the literature was used to, which covered a total of 28 research-based papers from computerized Scopus database.

Results demonstrated that except for Haegele et al (2017)/Meletti & Ribeiro (2104) among the studies, deficiencies exist in past literature relative to the adapted physical education in Brazilian public schools. In practical terms this highlights that the voice of children with special educational needs have not been heard yet in the official literature.

The objective of this work was to evaluate the effect of bean seed treatment with bay leaf on the physiological and sanitary quality of seeds stored at room temperature. The seeds were treated with concentrations of 1%, 2.5% and 5% w/w (measured in g/kg) and stored at room temperature in multiwall paper bags for a period of 24 months. The results indicate a decrease in germination after 24 months of storage for all treatments studied.

Municipal solid waste recycling cooperatives (MSWRCs) provide environmental benefits as well as better working and living conditions for waste pickers. This article analyzes the economic viability of a MSWRC in Brazil using economic-financial indicators, with data from September 2021. Economic viability was analyzed considering the net present value (NPV), annualized net present value (ANPV), internal rate of return (IRR), benefit-cost ratio (BCR) and discounted payback with a minimum attractiveness return rate (MARR) of 3% per year. Financial risk was evaluated using the Monte Carlo method, considering three scenarios for income and the remuneration of cooperative members. The base scenario (operating conditions prioritizing the remuneration of the members of the cooperative) places the future sustainability of the business at risk. Variations in the revenue from the sale of recyclable materials and in the remuneration of cooperative members exert a considerable influence on economic and financial indicators, representing a high risk of losses (between 23% and 26.6%). In conclusion, the future sustainability of MSWRCs depends on strategies for increasing revenue whether through the enterprises themselves or through public policies. The need for the better remuneration of cooperative members constitutes a challenge for management due to the need to make investments in the maintenance and growth of the production unit.","PeriodicalId":37865,"journal":{"name":"Fronteiras","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47618811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
