Effects of densification of poplar wood(Populus nigra) impregnated with nano-aluminum oxide(NA) and pre-treated with water vapor for 4 and 6 h were investigated in the present study. Physical and mechanical properties of treated poplar wood were measured according to the ASTM D-143 standard specifications, and then compared with the untreated specimens. Results showed significant improvement in all properties as a result of densification. A 4-h vapor pre-treatment improved effects on both physical and mechanical properties. When the duration of vapor-treatment increased to 6 h, wood polymers degraded to the extent that the improvements due to the vapor pre-treatment decreased substantially, though the final results were still significant improvements compared with the control specimens. High thermal conductivity coefficient of NA slightly but not significantly improved properties. Due to the high spring-back after 15 days,densified poplar is not recommended for applications in which densified wood will be exposed for long periods to high humidity or to direct water. 展开更多

A 4-week low dosage (500 mg/day) L-carnitine supplementation in combination with motivation training was carried out in 24 overweight (BMI 25.8 - 26.6 kg/m2) Japanese males in the course of a double-blind randomized placebo-controlled study. L-carnitine motivated group showed significant body weight loss and a decrement of serum triglyceride level vs. the non-motivated placebo group. Serum adiponectin levels increased in both L-carnitine supplemented groups. The beneficial effects of L-carnitine were amplified by motivation training. For clinical evaluation of supplements, whose efficacy is potentially affected by inter-individual life style variability, supportive motivation training might be advisable for future clinical trials. 展开更多

Kinetic parameters of the decomposition of hazardous chemicals can be applied for the estimation of their thermal behavior under any temperature profile.Presented paper describes the application of the advanced kinetic approach for the determination of the thermal behavior also under adiabatic conditions occurring e.g.in batch reactors in case of cooling failure.The kinetics of the decomposition of different samples(different manufacturers and batches) of 3-methyl-4-nitrophenol were investigated by conventional DSC in non-isothermal(few heating rates varying from 0.25 to 8.0K/min) and isothermal(range of 200~260℃) modes.The kinetic parameters obtained with AKTS-Thermokinetics Software were applied for calculating reaction rate and progress under different heating rates and temperatures and verified by comparing simulated and experimental signals.After application of the heat balance to compare the amount of heat generated during reaction and its removal from the system,the knowledge of reaction rate at any temperature profiles allowed the determination of the temperature increase due to the self-heating in adiabatic and pseudo-adiabatic conditions.Applied advanced kinetic approach allowed simulation the course of the Heat-Wait-Search(HWS) mode of operation of adiabatic calorimeters.The thermal safety diagram depicting dependence of Time to Maximum Rate(TMR) on the initial temperature was calculated and compared with the results of HWS experiments carried out in the system with Ф-factor amounting to 3.2.The influence of the Ф-factor and reaction progress reached at the end of the HWS monitoring on the TMR is discussed.Presented calculations clearly indicate that even very minor reaction progress reduces the TMRad of 24h characteristic for a sample with initial reaction progress amounting to zero.Described estimation method can be verified by just one HWS-ARC,or by one correctly chosen ISO-ARC run of reasonable duration by knowing in advance the dependence of the TMR on the initial temperature for any Ф-factor.Proposed procedure results in significant shortening of the measuring time compared to a safety hazard approach based on series of ARC experiments carried out at the beginning of a process safety evaluation. 展开更多

A new method for the fast detection and evaluation of optimization potentials for separation processes is presented within this work. The method disclaims the application of difficult rigorous mathematical optimization techniques by a number of different smart workarounds. The basis for the optimization is the application of different heuristics, shortcut methods and simulation studies. The method was applied to a real process in which the overall yield was improved of about 58%. Due to the new configuration an alternative control scheme containing unusual control loops was implemented. 展开更多

This study evaluated the relationship between serum L-carnitine level and sperm parameters in young boars. Serum L-carnitine and semen characteristics were determined for 61 young Duroc boars between the ages of 590 and 630 days. Multiple linear regression analysis was performed to predict total and progressive motility and the total number of spermatozoa based on serum total L-carnitine and free L-carnitine levels. Total number of spermatozoa was not associated with basal serum L-carnitine levels. A regression equation was found in which both total L-carnitine levels and free L-carnitine levels were significant predictors of total and progressive motility (P 0.05). These results suggest that serum L-carnitine level is an important selection parameter for stock boars. 展开更多

Background Specific nutrients combined with exercise may prevent a loss of lean body mass and consequently prevent sarcopenia.We examined the effects of 2 weeks of supplementation with L-carnitine and a single dose of branched-chain amino acids(BCAAs)on energy metabolism and body composition before and after exercise and on post-exercise muscle soreness in healthy subjects.Methods A total of 12 young,untrained,healthy women were randomly assigned to two groups who received either 2 weeks of supplementation with L-carnitine(1000 mg/day)and a single dose of BCAAs plus 200 kcal energy(LCAR+BCAA group,n=6)or 200 kcal energy alone(control group,n=6)before 60 min of exercise.Energy substrate metabolism and body composition by bio-impedance were examined before and after exercise.Delayed-onset muscle soreness(DOMS)was evaluated by using a visual analogue scale for 3 days after exercise.Results Serum concentrations of free and acyl-L-carnitine in the LCAR+BCAA group were not significantly different from those in the control group.There were no significant differences in body composition before or after exercise between the two groups.Although serum free fatty acid levels 120 min after the oral ingestion of BCAAs were significantly lower in the LCAR+BCAA group than in the control group,there were no significant differences in serum free fatty acid levels immediately after and 60 min after exercise.DOMS for 3 days after exercise was lower in the LCAR+BCAA group than in the control group,but this difference was not significant.Conclusion Continuous supplementation with L-carnitine combined with a dose of BCAAs in young,untrained,healthy subjects caused a blunted response of stimulated lipolysis after exercise. 展开更多

In the phloem cap region o i Arabidopsis plants,sulfur-rich cells(S-cells)accumulate>100 mM glucosinolates(GLS),but are biosynthetically inactive.The source and route of S-cell-bound GLS remain elusive.In this study,using single-cell sampling and scanning electron microscopy with energy-dispersive X-ray analysis we show that two GLS importers,NPF2.10/GTR1 and NPF2.11/GTR2,are critical for GLS accumulation in S-cells,although they are not localized in the S-cells.Comparison of GLS levels in S-cells in multiple combinations of homo-and heterografts o lg t r l gtr2,biosynthetic null mutant and wild-type plants indicate that S-cells accumulate GLS via symplasmic connections either directly from neighboring biosynthetic cells or indirectly to non-neighboring cells expressing GTR1/2.Distinct sources and transport routes exist for different types of GLS,and vary depending on the position of S-cells in the inflorescence stem.Based on these findings,we propose a model illustrating the GLS transport routes either directly from biosynthetic cells or via GTR-mediated import from apoplastic space radially into a symplasmic domain,wherein the S-cells are the ultimate sink.Similarly,we observed accumulation of the cyanogenic glucoside defensive compounds in high-turgor cells in the phloem cap of Lotus japonicus,suggesting that storage of defensive compounds in high-turgor cells may be a general mechanism for chemical protection of the phloem cap. 展开更多

Most organisms adjust their development according to the environmental conditions.For the majority,this implies the sensing of alterations to cell walls caused by different cues.Despite the relevance of this process,few molecular players involved in cell wall sensing are known and characterized.Here,we show that the wall-associated kinase-like protein RESISTANCE TO FUSARIUM OXYSPORUM 1(RFO1)is required for plant growth and early defense against Fusarium oxysporum and functions by sensing changes in the pectin methylation levels in the cell wall.The RFO1 dwell time at the plasma membrane is affected by the pectin methylation status at the cell wall,regulating MITOGEN-ACTIVATED PROTEIN KINASE and gene expression.We show that the extracellular domain of RFO1 binds de-methylated pectin in vitro,whose distribution in the cell wall is altered during F.oxysporum infection.Further analyses also indicate that RFO1 is required for the BR-dependent plant growth alteration in response to inhibition of pectin de-methyl-esterase activity at the cell wall.Collectively,our work demonstrates that RFO1 is a sensor of the pectin methylation status that plays a unique dual role in plant growth and defense against vascular pathogens. 展开更多
