A method to create smart and flexible switches for the regulation of liquid flow across multiple channels is essential in paper microfluidics. Prior approaches are hampered by long response times, high actuation fluid volumes, and external control circuitry. To diminish these problems, we designed a distinctive actuator device fashioned entirely from chromatography paper and featuring folds. The fold can be selectively wetted by an actuation fluid at either the crest or trough, resulting in t...
Abstract Food drying is one of the methods for preserving perishable foods for long periods of time. The nutritional composition of tomato (Lycopersicum esculentus) and okra (Abelmoschus esculentum) was investigated using the commonly available drying methods (sun, oven, and solar drying). The nutritional compositions of these food crops were determined after they have been dried using various drying methods and milled to pass through mesh size. The moisture content of these food samples wa...
Abstract Garden egg is a plant with edible fruit and its potential as a medicinal fruit have also been investigated. Extract has been suggested to have effects that could be therapeutic and nutritional. Analyses were carried out to determine the proximate and phytochemical constituents of both processed and raw indigenous Africa eggplant (Solanum macrocarpon and solanum aethiopicum). Proximate analysis of process and raw solanum macrocarpon (WBA) per (100%) showed: 75.13% moisture, 3.50% ...
Abstract The study is to identify the presence of phytochemical composition, proximate composition and mineral composition of the fruit, leave, bark and root of Africa Black Velvet Tamarind (dialium guineense). It is aimed at investigating the nutritionall constituenrs of the fruit, leave, bark and root of Africa Black Velvet tamarind. The crude extract were obtained and were screened for the presence of Phytochemicals, in order to identify the therapeutic potential of the plant. The result ...
Abstract People usually think food processing bring about reduction in food nutrients as well as the quantity because few quantities must have been lost or wasted during processing, many said food processing affect the taste and color of the food when compared to its whole form. Meanwhile, food processing which also includes its preparation makes food last longer than when in its whole form (increases its shelf life), although its positive effects are numerous but its negative effects canno...

ABSTRACT Urban development in wetland ecosystems for human settlement, agriculture and industrial development is one of the biggest threats to wetland conversion and management. Prediction of future urban expansion is very useful for urban planners and environmental managers in rapidly growing cities. This study aims to examine urbanization and loss of wetland in the Port-Harcourt metropolis, using remote sensing techniques. The study analyzes land use /land cover changes (LULC) using landsa...
Pollution of soil with lead (Pb) and cadmium (Cd) has been gaining researchers’ attention because of their adverse health effects on the safety of the food chain and environmental health. Hence, their immobilization in the soil is of great interest to environmental scientists globally. In this study, eggshell-biochar modified with nanoscale zerovalent iron/activated carbon (ESB-nZVI/AC) were synthesized via carbothermal reduction synthesis and compared their immobilization efficiency at...
ABSTRACT Experimental research on soil amendment using poultry manure on the growth of improved maize seeds (SUWAN-1-SR) in diesel oil-contaminated soil was carried out at the Research farm behind the Department of Botany, site II, Delta State University, Abraka. The experiment was laid out in Randomized Complete Block Design with four replicates. Rates of poultry manure applied were Og, 2g, 4g, 6g, 8g, and 10g. Data collected were plant height, stem girth, number of leaves, and leaf area.
Five years after Super Typhoon Haiyan, mangroves have regrown, and mangrove-climbing sesarmid crabs were found in Cancabato Bay. In a three-month surveillance, four species of mangrove-climbing sesarmid crabs: Aratus pisonii, Episesarma versicolor, Perisesarma bidens, and Selatium brockii were observed in mangrove trees: Avicennia marina, Aegiceras corniculatum, Rhizophora mucronata, and Rhizophora apiculata. They were observed moving into the different parts of the mangrove tree and from one...
Diel patterns of epifaunal macroinvertebrates associated with seagrass beds are poorly investigated. This pattern indicated misconception in population and community dynamics, diel cycle, and overall functional activities in an ecosystem. A three-day diel sampling period was permanently established in four stations in Eastern Samar, Philippines, patterned of the same sites in an unpublished study by Pacoma, 2016. Collecting samples was done at 7:00-9:00 am and 7:00-9:00 pm, using a transect-q...
ABSTRACT The concept of Agriculture products and yield information system has been described as the integration and utilization of information technology system in farming related operations. Agriculture is a traditional trade and operations involved in production, having largely remained habitual in nature. Traditional methods of farming incorporated little or no use of information technology, despite its potential for dramatically increasing operations efficiency. The incorporation of inf...
