| 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 |

| 4 | Heat Transfer and Energy Analysis of a Pusher Type Reheating Furnace Using Oxygen Enhanced Air for Combustion显示文摘Oxy-fuel firing is more energy efficient and environmental friendly than conventional air-fuel firing and its application to reheating furnaces has begun since 1990s.A computational method was presented to predict the steady heat transfer to the billets and temperature distribution in a continuous pusher type reheating furnace in which combustion air was enhanced by oxygen.Radiation heat flux calculated from the radiation heat exchange within the furnace was modeled using the FVM considering the effects of furnace walls and billets.Energy consumption per ton of steel,production rate and thermal efficiency of furnace,and trend of NOx emission in various levels of oxygen enrichment were investigated by comparing with baseline furnace(21% of O2 in air).The results showed that the best range of oxygen enrichments was between 21% and 45% by volume,as the higher slope of flame temperature and production increase occur in this range.The reduction of energy consumption can be obtained up to 18% per ton of steel for oxygen enrichment of 60% by volume. | Hamzeh Jafar Karimi Mohammad Hassan Saidi | 2010 | Journal of Iron and Steel Research(International)2010，17，4： | 7 |
| 5 | UFMylation of RPL26 links translocation-associated quality control to endoplasmic reticulum protein homeostasis显示文摘Protein biogenesis at the endoplasmic reticulum(ER)in eukaryotic cells is monitored by a protein quality control system named ER-associated protein degradation(ERAD).While there has been substantial progress in understanding how ERAD eliminates defective polypeptides generated from erroneous folding,how cells remove nascent chains stalled in the translocon during co-translational protein insertion into the ER is unclear.Here we show that ribosome stalling during protein translocation induces the attachment of UFM1,a ubiquitin-like modifier,to two conserved lysine residues near the COOH-terminus of the 60S ribosomal subunit RPL26(uL24)at the ER.Strikingly,RPL26 UFMylation enables the degradation of stalled nascent chains,but unlike ERAD or previously established cytosolic ribosome-associated quality control(RQC),which uses proteasome to degrade their client proteins,ribosome UFMylation promotes the targeting of a translocation-arrested ER protein to lysosomes for degradation.RPL26 UFMylation is upregulated during erythroid differentiation to cope with increased secretory flow,and compromising UFMylation impairs protein secretion,and ultimately hemoglobin production.We propose that in metazoan,co-translational protein translocation into the ER is safeguarded by a UFMylation-dependent protein quality control mechanism,which when impaired causes anemia in mice and abnormal neuronal development in humans. | Lihui Wang Yue Xu Heather Rogers Layla Saidi Constance Tom Noguchi Honglin Li Jonathan Wilson Yewdell Nicholas Raymond Guydosh Yihong Ye | 2020 | Cell Research2020，30，1： | 5 |
| 6 | Carbothermic Reduction of Zinc Oxide Concentrate by Microwave显示文摘Industrial application of microwave, as a heating source for material processing, was reviewed. The feasibility ofcarbothermic reduction of zinc oxide concentrate, as well as the effect of operating parameters was investigated,using a home style microwave oven at 2.45 GHz. Zinc oxide concentrate does not effectively absorb microwaveenergy, while any source of carbon, which is used as the reduction agent, absorbs microwave energy very well. In thisrespect coke breeze was found to be the best, and thus, coke was used both as the reducing agent and the absorbentof microwave energy. It was also found that any increase in the carbon content and size, increases the reductionrate. Increasing the microwave power and the size of the sample could also increase the reduction rate. Furtherinvestigation shows that when zinc oxide is exposed to the microwave for some time, the rate of the reduction byconventional method increases. | Ali Saidi Kamran Azari | 2005 | Journal of Materials Science & Technology2005，21，5： | 4 |
| 7 | Effectiveness of MRA on embolized intracranial aneurysms: a comparison of DSA, CE-MRA, and TOF-MRA显示文摘Purpose: The endovascular treatment of intracranial aneurysms was proven safe and effective compared to the alternative method of surgical clipping, despite the high recurrence rate. Follow-up of embolized intracranial aneurysms is mandatory for the early detection of recurrence and improved outcomes. DSA is used as the reference standard for this assessment. To determine the effectiveness of MRA in follow-up evaluations of intracranial aneurysms after embolization by comparing DSA, CE-MRA, and TOF-MRA. Materials and Methods: Sixty-eight consecutive patients undergoing DSA, TOF-MRA, and CE-MRA during an interval of <1 week were enrolled in this 6-month study. Images were evaluated for occlusion status, patency of the parent vessels, and artifacts. The modified Raymond-Roy occlusion classification and Aneurysm Embolization Grades were used to assess the occlusion status and initial DSA images for detection of recurrence in two filtered study phases with optimized selection criteria. Seventeen observers(phase I: 9, phase II: 8) independently interpreted the double-blinded images. Agreement was expressed with a Fleiss kappa value; p < 0.05 was considered significant. Results: This study included 68 patients with 77 aneurysms; 38(49.35%) were treated with coil alone and 39(50.65%) with stent-assisted coiling. In both phases, DSA was superior to TOF-MRA and CE-MRA using MRRC(Phase I: k = 0.567, p ≤ 0.001; k = 0.287, p ≤ 0.001; k = 0.117, p ≤ 0.001, respectively; Phase II: k = 0.503, p ≤ 0.001; k = 0.303, p ≤ 0.001; k = 0.115, p = 0.038, respectively). TOF-MRA was as effective as DSA(TOF: k = 0.335, p ≤ 0.001; DSA: k = 0.323, p ≤ 0.001) for recurrence detection. Conclusion: We suggest TOF-MRA as a first-line follow-up tool to detect aneurysm recurrence, and DSA to quantify the filling space to make a definite decision on re-embolization. | Ally Mohamed Qassim Sheng Guan Halfan Saidi Ngowo Binghui Liu Haowen Xu | 2018 | Journal of Interventional Medicine2018，1，1： | 4 |
| 8 | Distracted walking:Examining the extent to pedestrian safety problems显示文摘Pedestrians,much like drivers,have always been engaged in multi-tasking like using handheld devices,listening to music,snacking,or reading while walking.The effects are similar to those experienced by distracted drivers.However,distracted walking has not received similar policies and effective interventions as distracted driving to improve pedestrian safety.This study reviewed the state-of-practice on policies,campaigns,available data,identified research needs,and opportunities pertaining to distracted walking.A comprehensive review of literature revealed that some of the agencies/organizations disseminate useful information about certain distracting activities that pedestrians should avoid while walking to improve their safety.Various walking safety rules/tips have been given,such as not wearing headphones or talking on a cell phone while crossing a street,keeping the volume down,hanging up the phone while walking,being aware of traffic,and avoiding distractions like walking with texting.The majority of the past observational-based and experimental-based studies reviewed in this study on distracted walking is in agreement that there is a positive correlation between distraction and unsafe walking behavior.However,limitations of the existing crash data suggest that distracted walking may not be a severe threat to the public health.Current pedestrian crash data provide insufficient information for researchers to examine the extent to which distracted walking causes and/or contributes to actual pedestrian safety problems. | Judith Mwakalonge Saidi Siuhi Jamario White | 2015 | Journal of Traffic and Transportation Engineering(English Edition)2015，2，5： | 3 |

| 11 | Current status of glucocorticoid usage in solid organ transplantation显示文摘Glucocorticoids(GCs)have been the mainstay of immunosuppressive therapy in solid organ transplantation(SOT)for decades,due to their potent effects on innate immunity and tissue protective effects.However,some SOT centers are reluctant to administer GCs long-term because of the various related side effects.This review summarizes the advantages and disadvantages of GCs in SOT.PubMed and Scopus databases were searched from 2011 to April 2021 using search syntaxes covering“transplantation”and“glucocorticoids”.GCs are used in transplant recipients,transplant donors,and organ perfusate solution to improve transplant outcomes.In SOT recipients,GCs are administered as induction and maintenance immunosuppressive therapy.GCs are also the cornerstone to treat acute antibody-and T-cell-mediated rejections.Addition of GCs to organ perfusate solution and pretreatment of transplant donors with GCs are recommended by some guidelines and protocols,to reduce ischemia-reperfusion injury peri-transplant.GCs with low bioavailability and high potency for GC receptors,such as budesonide,nanoparticle-mediated targeted delivery of GCs to specific organs,and combination use of dexamethasone with inducers of immuneregulatory cells,are new methods of GC application in SOT patients to reduce side effects or induce immune-tolerance instead of immunosuppression.Various side effects involving different non-targeted organs/tissues,such as bone,cardiovascular,neuromuscular,skin and gastrointestinal tract,have been noted for GCs.There are also potential drug-drug interactions for GCs in SOT patients. | Simin Dashti-Khavidaki Reza Saidi Hong Lu | 2021 | World Journal of Transplantation2021，11，11： | 3 |
