Dataset describing plant materials used in the Colombian cotton production system

This dataset describes Upland cotton cultivars used for fiber production in Colombia in the last century. Data describing genealogy, yield and fiber quality traits of these cultivars (and the introduced ones mainly from USA) is scattered across grey literature which reduces chances of discovering, accessing and assessing this information. The data was extracted from grey literature mainly produced by ICA and CORPOICA (rebranded today as AGROSAVIA), the Colombian agricultural research agencies. The dataset also includes a description of cotton breeding lines developed by these institutions for adaptation to tropical environments specially for the monsoon and savanna climates: the LC and LCER series of Upland cotton breeding lines. Bibliographic description of the grey literature used for building this dataset is also included and can be provided under request

IMR, poverty and academic performance at municipality level in Colombia

This dataset contains data for multidimensional poverty, infant mortality rate (IMR) and academic performance at municipality level for Colombia. It was developed with the purpose of assessing regional inequality in Colombia in the decade between 2005 - 2015 and its effect over academic performance at the end of high school. This dataset includes 1106 municipalities describing: average IMRs during a decade (2005-2015), fifteen variables describing poverty in 2005 (extracted from census data) and normalized scores for the cognitive skills test for college admissions (CSTCA). Poverty and IMR can be used as proxy of economic development and population health and scores on standardized tests as proxy of academic achievement. This dataset was generated to provide better understanding of the inequality in Colombia at regional level. Colombia is a middle income country, and one of the most unequal economies in the world. Regional disparities of economic growth and development in Colombia are visible in terms of poverty, population health and education. The reported data cover 3 categories of indicators that can be used to proxy poverty, population health and education achievement. IMR, health access and academic performance information at municipality level were obtained from data repositories of the Colombian government agencies

EFFECT OF SULFATE LOADING RATE AND ORGANIC LOADING RATE ON ANAEROBIC BAFFLED REACTORS USED FOR TREATMENT OF SANITARY LANDFILL LEACHATES

AbstractThis study investigated the effect of organic loading rate (OLR) and sulfate loading rate (SLR) on landfill leachate treatment by a lab-scale anaerobic baffled reactor (ABR). Landfill leachate contained a concentration of organic matter between 3966 and 5090 mg COD.L-1 and no detectable amounts of sulfate. Reactors were started-up by feeding them with iron-sulfate at a SLR of 0.05 g SO42-.L-1.day-1 (4 weeks). Factorial design and response surface techniques were used to evaluate and optimize the effects of these operating variables on COD removal. ABRs were operated at OLRs ranging from 0.30 up to 6.84 g COD.L-1.day-1 by changes in influent volumetric flow. SO42- was added to the influent at a SRL from 0.06 to 0.13 g SO42-.L-1.day-1. The highest value of COD removal (66%) was reached at an OLR of 3.58 g COD.L-1.day-1 and SLR of 0.09 g SO4-2.L-1.day-1 with a COD/SO4-2 ratio of 40. Under these conditions sulfate is mainly used for molecular hydrogen consumption while organic matter is preferentially degraded via methanogesis
