Water quality monitoring through remote sensing with UAVs is best conducted using multispectral sensors; however, these sensors are expensive. We aimed to predict multispectral bands from a low-cost sensor (R, G, B bands) using artificial neural networks (ANN). We studied a lake located on the campus of Unisinos University, Brazil, using a low-cost sensor mounted on a UAV. Simultaneously, we co...

Hyperspectral imaging offers enormous potential for measuring grape composition with a high degree of representativity, allowing all exposed grapes from the cluster to be examined non-destructively. On-the-go hyperspectral images were acquired using push broom camera (400–100 nm) that was mounted in front part motorized platform moving at 5 km/h commercial Tempranillo vineyard La Rioja, Spain. ...

bananas are climacteric fruits and controlling ripening is effective in reducing loss. this experiment studied the effect of packaging (plastic bag, edible wax and plastic bag, plastic bag and 2 or 4 g/kg potassium permanganate) over 5 weeks of cold storage on the quality and characteristics of cavendish cultivar bananas. the samples were removed from storage at 8, 16, 24, 32 and 40 days and fr...

The environmental problems of paper board industry are not limited by the high water consumption, generate wastewaters and solid wastes. This paper presents the paper board industry effluent treatment plant components performance and physio-chemical characteristics of wastewater and sludge. In ETP operation most important factors is effluent characterization, flow rate, aeration tank dissolved ...

Twelve different liquid market milks of Bangladesh were examined to evaluate their chemical and sanitary quality. Six of these were open raw milk bought from local daily markets and the other six were processed packet milk (both pasteurized and UHT [Ultra High Temperature] processed) available in shops. The twelve samples were examined for the determination of percentage of water, total soluble...

pomegranate is one of the major horticultural crops in iran, but studies about this product; especially its pruning is very little. therefore this study was carried out to assess the effect of pruning and nutrition on pomegranate cultivar “robab” in qaemieh, fars province during 2008-2009. this research was conducted factorial experiment based on randomized complete block design (rcbd) with 5 p...

A quantitative comparative study was performed to assess the relative applicability of Total Suspended Solids (TSS) models published in the last decade for the Moderate Resolution Imaging Spectroradiometer (MODIS) and Landsat-based sensors. The quantitative comparison was performed using a suite of statistical tests and HydroLight simulated data for waters ranging from clear open ocean case-1 t...

Food-service establishments that use on-site wastewater treatment systems are experiencing pretreatment system and/or drain field hydraulic and/or organic overloading. This study included characterization of four wastewater parameters (five-day biochemical oxygen demand [BOD5]; total suspended solids [TSS]; food, oil, and grease [FOG]; and flow) from 28 restaurants located in Texas during June,...

Abstract Garifta-merah is one of the mango varieties released by Ministry Agriculture in 2009 with advantage having red-yellow peel when it reaches full maturity. The distinctive taste fruit flesh makes types mangoes favored consumers local and foreign countries. As a new variety, there not much data regarding mango, especially optimal maturity stage to harvest. This study aims determine physic...
