Cereal is an essential source of calories and protein for the global population.Accurately predicting cereal quality before harvest is highly desirable in order to optimise management for farmers,grading harvest and categorised storage for enterprises,future trading prices,and policy planning.The use of remote sensing data with extensive spatial coverage demonstrates some potential in predicting crop quality traits.Many studies have also proposed models and methods for predicting such traits based on multiplatform remote sensing data.In this paper,the key quality traits that are of interest to producers and consumers are introduced.The literature related to grain quality prediction was analyzed in detail,and a review was conducted on remote sensing platforms,commonly used methods,potential gaps,and future trends in crop quality prediction.This review recommends new research directions that go beyond the traditional methods and discusses grain quality retrieval and the associated challenges from the perspective of remote sensing data.

The suitability of the abundant agro-industrial residues wheat straw(WS;control),barley and oats straw(BOS)and rice husk(RH),supplemented with various sources of oils(sunflower,corn oil),nitrogen(peptone,yeast extract)and calcium salts(CaSO_(4)⋅2H_(2)O,CaCl2),as novel substrates in solid-state fermentation of selected Pleurotus ostreatus and P.eryngii mushrooms was investigated.The possible effect of different additives on mycelial growth rate,biomass production and endoglucanase,laccase and lipase biosynthesis were evaluated.Moreover,their impact on essential cultivation aspects(earliness,total mushroom yield,biological efficiency)and carposome quality parameters(weight,morphological characteristics)was assessed.Both fungi showed their highest growth rates on BOS substrates and the most positive implementation was CaSO_(4)⋅2H_(2)O 6%w/w(Kr=9.58 mm/day;P.ostreatus,Kr=9.42 mm/day;P.eryngii),while different additives led to enhancement of biomass production.Pleurotus species demonstrated minimal levels of endoglucanase activity,with values ranging from 0.01 to 0.42 U/g of dry weight,regardless of the substrate and the stage of colonization.On the contrary,the maximum values of laccase activity were observed at 50%of colonization on BOS and RH,while supplementation with nitrogen and calcium sources positively affected its biosynthesis.P.ostreatus and P.eryngii cultivated on BOS supplemented with peptone at 2 and 5%w/w,synthesized significant laccase amounts,i.e.,12,165.78 and 8,624.55 U/g d.w.,respectively.Satisfactory amounts of lipase were produced,especially in substrates supplemented with sunflower 2%w/w,in quantities up to 1.42 U/g d.w.,whereas the highest lipase activity was achieved by P.eryngii on WS supplemented with corn oil at 2%w/w,with a value of 4.25 U/g d.***.being recorded.Regarding fermentation of Pleurotus species in polypropylene bags,WS and BOS supported faster colonization and shorter earliness period than RH substrates,whereas supplementation did not seem to affect these culture parameters.Furthe

Interspecific density-dependent model of predator-prey relationship in the chemostat

引用

International Journal of Biomathematics 2021年第1期14卷 51-72页

The objective of this study is to analyze a model of competition for one resource in the chemostat with general interspecific density-dependent growth rates,taking into account the predator–prey relationship.This relationship is characterized by the fact that the prey species promotes the growth of the predator species which in turn inhibits the growth of the first species.The model is a three-dimensional system of ordinary differential equations.With the same dilution rates,the model can be reduced to a planar system where the two models have the same local and even global behavior.The existence and stability conditions of all steady states of the reduced model in the plane are determined according to the operating parameters.Using the nullcline method,we present a geometric characterization of the existence and stability of all equilibria showing the multiplicity of coexistence steady states.The bifurcation diagrams illustrate that the steady states can appear or disappear only through saddle-node or transcritical bifurcations.Moreover,the operating diagrams describe the asymptotic behavior of this system by varying the control parameters and show the effect of the inhibition of predation on the emergence of the bistability region and the reduction until the disappearance of the coexistence region by increasing this inhibition parameter.

The productivity of two serial chemostats

This paper considers the production of biomass of two interconnected chemostats in series with biomass mortality and a growth kinetic of the biomass described by an increasing function.A comparison is made with the productivity of a single chemostat with the same mortality rate and with volume equal to the sum of the volumes of the two chemostats.We determine the operating conditions under which the productivity of the serial configuration is greater than the productivity of the single chemostat.Moreover,the differences and similarities in the results corresponding to the case with mortality and the one without mortality,are highlighted.The mortality leads to surprising results where the productivity of a steady state where the bacteria are washed out in the first chemostat is greater than the one where the bacteria are present in both chemostats.
