| 1 | Microbiological parameters and maturity degree during composting of Posidonia oceanica residues mixed with vegetable wastes in semi-arid pedo-climatic condition显示文摘The aim of this study was to characterize the biological stability and maturity degree of compost during a controlled pile-composting trial of mixed vegetable residues (VR) collected from markets of Tunis City with residues of Posidonia oceanica (PoR), collected from Tunis beaches. The accumulation in beaches (as well as their removal) constitutes a serious environmental problem in all Mediterranean countries particularly in Tunisia. Aerobic-thermophilic composting is the most reasonable way to profit highly-valuable content of organic matter in these wastes for agricultural purposes. The physical, chemical, and biological parameters were monitored during composting over 150 d. The most appropriate parameters were selected to establish the maturity degree. The main result of this research was the deduction of the following maturity criterion: (a) C/N ratio < 15; (b) NH4+-N < 400 mg/kg; (c) CO2-C < 2000 mg CO2-C/kg; (d) dehydrogenase activity < 1 mg TPF/g dry matter; (e) germination index (GI) > 80%. These five parameters, considered jointly are indicative of a high maturity degree and thus of a high-quality organic amendment which employed in a rational way, may improve soil fertility and soil quality. The mature compost was relatively rich in N (13.0 g/kg), P (4.74 g/kg) and MgO (15.80 g/kg). Thus composting definitively constitutes the most optimal option to exploit these wastes. | SAIDI Neyla KOUKI Soulwene M'HIRI Fadhel JEDIDI Naceur MAHROUK Meriam HASSEN Abdennaceur OUZARI Hadda | 2009 | Journal of Environmental Sciences2009，21，10： | 32 |
| 2 | Isolation and characterization of facultative mixotrophic ammonia-oxidizing bacteria from constructed wetlands显示文摘Autotrophic ammonia-oxidizing bacteria (AOB) have been widely studied in constructed wetlands systems,while mixotrophic AOB have been less thoroughly examined.Heterotrophic bacteria were isolated from wastewater and rhizospheres of macrophytes of constructed wetlands,and then cultivated in a mixotrophic medium containing ammonium and acetic acid.A molecular characterization was accomplished using ITS-PCR amplification,and phylogenetic analysis based on 16S rRNA gene sequences.Results showed the presence of 35 bacteria,among 400 initially heterotrophic isolates,that were able to remove ammonia.These 35 isolates were classified into 10 genetically different groups based on ITS pattern.Then,a collection of 10 isolates were selected because of their relatively high ammonia removal efficiencies (ARE 80%) and their phylogenetic diversity.In conditions of mixotrophy,these strains were shown to be able to grow (increase of optical density OD 660 during incubation with assimilation of nitrogen into cellular biomass) and to oxidize ammonia (important ammonia oxidation efficiencies,AOE between 79% and 87%).Among these facultative mixotrophic AOB,four isolates were genetically related to Firmicutes (Bacillus and Exiguobacterium),three isolates were affiliated to Actinobacteria (Arthrobacter) and three other isolates were associated with Proteobacteria (Pseudomonas,Ochrobactrum and Bordetella). | Soulwène Kouki Neila Saidi Fadhel M'hiri Houda Nasr Hanène Cherif Hadda Ouzari Abdennaceur Hassen | 2011 | Journal of Environmental Sciences2011，23，10： | 9 |
| 3 | An Approach to Polynomial NARX/NARMAX Systems Identification in a Closed-loop with Variable Structure Control显示文摘Many physical processes have nonlinear behavior which can be well represented by a polynomial NARX or NARMAX model.The identification of such models has been widely explored in literature.The majority of these approaches are for the open-loop identification.However,for reasons such as safety and production restrictions,open-loop identification cannot always be done.In such cases,closed-loop identification is necessary.This paper presents a two-step approach to closed-loop identification of the polynomial NARX/NARMAX systems with variable structure control(VSC).First,a genetic algorithm(GA) is used to maximize the similarity of VSC signal to white noise by tuning the switching function parameters.Second,the system is simulated again and its parameters are estimated by an algorithm of the least square(LS) family.Finally,simulation examples are given to show the validity of the proposed approach. | O.M.Mohamed Vall R.M'hiri | 2008 | International Journal of Automation and computing2008，5，3： | 6 |
