The consumption of special coffees has been gradually increasing and affecting in their prices, not only for the domestic market; but also in the foreign market. The different methods of coffee processing will directly influence the cup quality. Taking this into consideration, this study has as an objective evaluated the cup quality of two varieties of Peruvian special coffee subjected to submerged fermentation. This research was done in a Central Composite Rotational Design (CCRD) containing four factorial experiments, four axial experiments and three core repeats. It was evaluated the cup quality of two varieties of coffee subjected to different temperatures (8, 9, 12, 15 and 16 °C) and fermentation times (48, 62, 96,130 and 144) submerged in relation 70:30; having as a result that the geisha variety presents greater values than 86 points, continued by caturra variety with less values...

In the absence of local studies, the current study was conducted in four villages located in the province of Cajabamba (Cajamarca, Peru) to demonstrate and determine the point prevalence of enteric nematodes in guinea pigs (Cavia porcellus) raised in a family-commercial breeding system. A total of 384 faecal samples were collected from guinea pigs and processed using the Sheather Sugar method. The eggs of P. uncinata, Trichuris spp., and Capillaria spp. were identified in guinea pigs from all four villages, resulting in an overall prevalence of 66.15±4.73%. Among the villages, the highest prevalence was observed in Naranjos, with a prevalence of 78.16±8.68% (68 out of 87 guinea pigs). This was followed by Malcas with a prevalence of 67.24±8.54% (78 out of 116 guinea pigs), Ogosgуn-Paucamonte with a prevalence of 64.08±9.27% (66 out of 103 guinea pigs), and La Esperanza with a preval...

The 2022 mean temperature for central South America was 0.23°C above the 1991–2020 average (Fig. 7.13). Much of the region had near- to above-average mean annual temperatures (Fig. 7.11). Seasonally, during December–February, much of the northern half of Brazil and some areas in northwestern Peru and southwestern Bolivia had near- to below-average temperatures. Meanwhile, the rest of region had near- to above-average conditions. During boreal autumn (March–May), most of the region experienced near- to above-average temperatures, with southern Peru and southwestern Bolivia observing below-average temperatures. Above-average temperatures also encompassed much of the region during boreal winter (June–August), with some locations experiencing mean temperature anomalies that were +2°C or higher. Parts of southern Peru continued to experience near- to below-average conditions during ...
