Abstract According to the WHO, almost two thirds of the Ethiopian population are at risk of contracting malaria, where infection with Plasmodium falciparum accounts for approximately 60% of cases today. The risk of artemisinin resistance spreading from SE Asia to Africa is a major concern. We conducted a 28-day in vivo efficacy trial of Artemether-Lumefantrine (Co-Artem) for treatment of uncomplicated malaria (n = 97) in the Gondar Region, North West Ethiopia in 2017–2018. Our results confirmed 100% adequate clinical and parasitological response (ACPR) with no parasites observed at day 3 by microscopy. Further analysis of day 0 samples showed the expansion of a kelch13 mutation R622I to 9.5% from 2.4% of isolates reported three years earlier. Closer examination of the R622I mutation in vitro is warranted.

O Brasil mantém a segunda maior produção de abacaxi do mundo, movimentando bilhões e empregando milhares de pessoas anualmente. Contudo, a abacaxicultura no Nordeste ainda é insipiente, destacando-se principalmente nos estados da Paraíba e Bahia. As características morfológicas da planta apresentam resistência ao clima semiárido, podendo ser produzida nessas áreas sem grandes restrições. Dessa forma, este estudo tem como objetivo mapear a potencialidade, do ponto de vista geoclimático, à produção do abacaxi na microrregião de Araripina, a partir de aspectos físico-naturais e de uso de solo, procurando adequar a cultura do abacaxi à baixa oferta hídrica da região semiárida, de modo a otimizar o uso da água na região. Para tanto uma carta de potencialidade geoclimática foi gerada por meio do cruzamento de informações das cartas de geomorfologia, pedologia, índices pluviométricos anuais e uso e ocupação do solo, também sendo estimada a evapotranspiração da cultura do abacaxi e a necessidade hídrica da cultura na região. Os resultados indicaram que a microrregião de Araripina possui a predominância do grau de potencialidade à abacaxicultura das classes de “muito alta” a “alta”. Sendo a área cultivada na microrregião de aproximadamente 20ha de abacaxi, há uma demanda anual de 343.373m³ num sistema de irrigação por aspersão e de 286.512m³ de água num sistema de microaspersão para suprir as deficiências hídricas dessa cultura. Portanto, a irrigação e o manejo adequado do solo são atributos necessários para o desenvolvimento viável e competitivo da cultura no semiárido.  ABSTRACTBrazil maintains a second world's largest pineapple production, moving billion and employing thousands of people annually. However, the pineapple culture on Northeast is still and incipient, highlighting especially on Paraiba and Bahia states.

Seven and one-half square miles, or 4864 acres, of the Grand Valley in Western Colorado consists of high water-using landscapes. Overirrigation of Grand Valley soils flushes 580,000 tons of salt into the Colorado River each year. These salts negatively impact plant and animal health throughout the Colorado River basin. Proper watering of lawns can significantly reduce this problem. Correcting problems with a sprinkler irrigation system can reduce water use by an average of 40%. If water use on all 4864 acres was reduced by 40%, a savings of 11,187 acre feet, or over 3.6 billion gallons, of water would result. The annual historical evapotranspiration (ET) rate for the Grand Valley of Western is ≈61 inches; the ET rate during the irrigation season (April through October) is ≈49 inches. Since a typical sprinkler system is ≈70% efficient, in order to apply 49 inches of water to the soil, ≈70 inches of water is required. Irrigation system problems such as improperly spaced heads, sunken heads and heads not adjusted are typically responsible for 40% more water being applied than necessary. In Western Colorado, this equates to an over-application of 28 inches (2.3 acre feet) of water being applied each year. The 2005 Western Colorado irrigation audit problem covering 18.7 acres of turf. Assuming the problems noted were all corrected, a water savings of 43 acre feet, or 14,013,797 gallons, of water resulted. The 2006 audit program will continue this educational and water-saving effort. A grant from the Department of the Interior-Bureau of Reclamation will help fund the 2006 Irrigation Audit project.
