to evaluate the effect of chemical and bio-fertilizer on nitrogen, phosphorus and potash concentration, biochemical traits and calyxes yield of roselle, an experiment was conducted in the split plot based on randomized coplete block design with three replications, at the research station in zabol university, during 2013 and 2014. the main plot consisted of three levels: phosphorus, nitrogen and...

Bio-entity name recognition is the key step for information extraction from biomedical literature. This paper presents a dictionary-based bio-entity name recognition approach. The approach expands the bio-entity name dictionary via the Abbreviation Definitions identifying algorithm, improves the recall rate through the improved edit distance algorithm and adopts some post-processing methods inc...

A variety of renewable starting materials, such as sugars and polysaccharides, vegetable oils, lignin, pine resin derivatives, and proteins, have so far been investigated for the preparation of bio-based polymers. Among the various sources of bio-based feedstock, vegetable oils are one of the most widely used starting materials in the polymer industry due to their easy availability, low toxicit...

in order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (foeniculum vulgare miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. arbuscular mycorrhizal fungi (strain sebacina vermifera) and phosphate dissolving bacteria (genera peseudomonas) were applied as ...

A literature review, a datasheet review, and in-house experimental data were used to obtain a real-world comparison between bio-mimetic pectoral fins and traditional propeller-based thrusters. Only power consumption, forward thrust, and propulsive efficiency are compared. Scaling trends for both propulsion forms are discussed. Traditional thrusters are determined to be more efficient than curre...

there is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. we aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

today, environment protection and safe crop production are very important. the management of soil elements by bio-fertilizers is considered as important point for sustainable agriculture. mode of action of fertilizers is very different in drought stress conditions. to evaluate biological fertilizers (agrohumic, nitroxin, superabsorbent and vermicompost) and compare them with current chemical fe...

Recovering valuable compounds from waste streams of bio-based production processes is in line with the circular economy paradigm, and is achievable by implementing “simple-to-use” and well-established process separation technologies. Such solutions are acceptable from industrial, economic and environmental points of view, implying relatively easy future implementation on pilotand full-scale lev...

Most bituminous adhesives or binders that are used for pavement materials are derived primarily from fossil fuels. With petroleum oil reserves becoming depleted and the drive to establish a bio-based economy, there is a push to produce binders from alternative sources, particularly from biorenewable resources. However, until now, no research has studied the applicability of utilizing bio-oils a...
