Four Steels,C-Mn-0.05V,C-Mn-0.11V,C-Mn-0.03nb and C-Mn were subjected to heat treatment to simulate the microstructure of a coarse grained heat affected zone (CGHAZ) and an intercritically reheated coarse grained heat affected zone (ICCGHAZ).this involved reheating to 1350°C,rapid cooling (Δt 8/5 =24s) to room temperature and then reheating to either 750°C or 800°*** toughness of the HAZs was assessed using both Charpy and CtOd *** features were characterised by optical,scanning` and transmission electron *** examinations of the Charpy and CtOd specimens were carried out to understand the micromechanism of fracture under different microstructural and test *** CGHAZ toughness was similar for the steels except that Steel C-Mn-0.05V had a slightly lower Itt compared to the *** toughness deteriorated in the ICCGHAZ for all the steels,again Steel C-Mn-0.05V had a superior toughness compared to the other three steels in both ICCGHAZ *** the level of vanadium to 0.11% caused a decrease in ICCGHAZ *** C-Mn-nb exhibited a greater degradation of impact toughness after the intercritical *** presence of M-A constituents was the dominant factor in determining the toughness of the *** size and area fraction of the M-A constituents were the smallest in Steel *** vanadium level to 0.11% resulted in a greater area fraction of the M-A constituents,larger average and maximum sizes of M-A particles,and significantly more fields containing the *** addition of 0.031% nb produced the largest M-A particles and the greatest area fraction for the steels tested.

Critical Limb Ischaemia (CLI) is defined as the presence of rest pain, ulcers and/or gangrene in a limb for over 2 weeks. Associated exercise intolerance is caused by muscle fibre atrophy, fibro- fatty infiltration, nerve dysfunction, mitochondrial damage and myofibril disorder. We aimed to determine the behaviour of satellite cells, responsible for the repair and regeneration of damaged muscle, in repairing the damage caused to critically ischaemic adult human skeletal muscle. Cd34, pax7 and Myod are all markers of satellite cells at different stages of the cell cycle and allow for an assessment of their number and activity in ischaemia. Local ethical committee approval and informed consent was obtained. Samples of harvested gastrocnemius muscle of patients undergoing major perigenicular amputation for CLI (n = 10) were analysed and compared to a control group undergoing coronary artery bypass grafting (n = 10). Using immunohistochemistry, the expression of pax7, Cd34 and Myod was assessed in five sequential blinded randomly generated fields. Statistical testing of the data collected was made via the Mann Whitney U test. Protein electrophoresis was used to confirm overall protein expression of the satellite cell markers. there was a significant increase in the number of satellite cells observed in CLI muscle sections as demonstrated by the expression of pax7 (2.4×?fold p ?Haematopoietic Stem Cells?(HSCs) and satellite cells were also more abundant, with a 2×?fold increase observed (p t those cells expressing both Cd34 and pax7 and identified as quiescent satellite cells, were significantly greater in number in the CLI samples (2.9×?fold p nfirmed via immunohistochemistry and protein electrophoresis. there was a significant decrease in the expression of Myod positive or activated satellite cells (p this indicates an increase in the proliferation of the satellite cell population as a response to CLI but less active cells are obs

Objective: to investigate the long-term differential drug effects on cognitiv e functioning in school-aged children exposed to antiepileptic drugs (AEds) in utero. Methods: Mothers with epilepsy were recruited from specialist epilepsy cl inics and obstetric clinics from the Liverpool and Manchester region. the mother s and their children were recruited without prior knowledge of their AEd treatme nt during pregnancy or the health of the offspring. A battery of neuropsychologi cal tests was applied to each mother-child pair in order to obtain a neuropsych ological profile for each child. Results: neuropsychological investigation was p erformed on 249 children between the ages of 6 and 16. Children exposed to sodiu m valproate had a significantly lower verbal IQ when compared to children expose d to other antiepileptic drugs or not exposed at all. the same children were mor e likely to have an IQ below 69 and more likely to have memory impairment when c ompared to the othergroups. the mothers’IQ, exposure to sodium valproate, and t he number of tonic-clonic seizures during pregnancy were significant predictors of verbal IQ in this population. Conclusions:this retrospective study highlights the potential harmful effects of sodium valproate exposure in utero on neuropsychological development.

A search for the doubly charmed baryon ■^+cc is performed through its decay to theΛ^+c K^-π^+ final state,using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7,8 and 13 *** data correspond to a total integrated luminosity of 9 fb^-*** significant signal is observed in the mass range from 3.4 to 3.8 GeV/c^*** limits are set at 95%credibility level on the ratio of the ■^+cc production cross-section times the branching fraction to that ofΛ^+c and ■^++cc *** limits are determined as functions of the ■^+cc mass for different lifetime hypotheses,in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/c.

Waste Cashew Apple (Anacardium occidentale) as Feedstock for Simultaneous Production of two Main Ecofriendly Fuels

Journal of Power and Energy Engineering 2023年第8期11卷 16-31页

作者： delphine n’guessan Micaël Bedikou Verdier Abouo Lamine Samagaci Charlotte Ehon Camara Yacouba Eric Akpa department of Biotechnologies Felix Houphou&#235t-Boigny University Abidjan C&#244te d’Ivoire departement of Food Sciences Felix Houphou&#235t-Boigny University Abidjan C&#244te d’Ivoire

the present work investigated an effective low-cost production of bioethanol by the use of rejected cashew apples (CAs) in Ivorian plantations. Fresh CAs were cut into 8-10 mm slices and submitted to a drying cycle of two periods (for the sake of easing their rehydration) in an oven with forced air convection. temperature was first set at 30˚C for 3 hours, and then raised at 50˚C until constant weight. drying brought about 82% weight loss, and the dried slices were rehydrated in a ratio of 1:4 (w/v) in warm distilled water to reconstitute a 10 Brix degree (˚B) juice with 1.042 g/cm3 density. the sugar content of the juice was increased to 20˚B (syrup) by thermal evaporation. the process was optimized using a response surface methodology (RSM) by applying a central composite plan in order to minimize heat-sensitive compound degradation. the optimal operating conditions for temperature and time of heating were precisely 68,239˚C and 83,314 min, respectively. the commercial baker’s yeast Saccharomyces cerevisiae was used to seed the 20˚B cashew apple syrup following a batch fermentation at 30˚C. the total alcohol content recorded after 24 hours was 8.24% ± 0.11% made up of almost 97% of ethanol and isobutanol (a higher alcohol). Analysis of alcoholic profiles by flam ionization detector-gas chromatography (GC-FId) showed an ethanol content of 3.92% and an almost similar but higher quantity of isobutanol (4.05%) with the latter being a by-product. As bio-based isobutanol attracts more and more attention due to its wide application and excellent fuel performance as compared to ethanol, it emerged from this study that neglected cashew apples can be successfully employed as valuable raw material for the simultaneous production of both biofuels currently used as sustainable sources of renewable energy.
