Flow regimes in wet conical spouted beds using glass bead mixtures

Particuology 2008年第2期6卷 72-80页

Using a high-viscosity Newtonian fluid, glycerol, an experimental investigation was carried out to evaluate the stable spouting regime in conical spouted beds using four particle mixtures： a reference （monoparticles）, a binary mixture, two ternary mixtures with flat and Gaussian distributions respectively. The mixtures were selected for particle diameters （dp） ranging from 1.09 to 4.98 mm and particle diameter ratios （dpL/dps） ranging from 1.98 to 4.0. Experimental data show that pressure fluctuation signals of the bed, as indicated by changes in their standard deviations, provide suitable information to identify the range of operational conditions for stable spouting. However, the analysis of skewness of curves of pressure fluctuation as a function of air velocity appears not sufficient to identify a particular flow regime. For glycerol in the spouting regime, the standard deviation is noted to increase with increasing glycerol concentration due to the growth of interparticle forces. The implications of these research findings on the drying of suspensions in conical spouted beds using glass bead mixtures are also discussed.

Natural Mg silicates with different structures and morphologies: Reaction with K to produce K2MgSiO4 catalyst for biodiesel production

In this work, different magnesium silicate mineral samples based on antigorite, lizardite, chrysotile(which have the same general formula Mg3Si2O5(OH)4), and talc(Mg3Si4O10(OH)2) were reacted with KOH to prepare catalysts for biodiesel production. Simple impregnation with 20 wt% K and treatment at 700–900°C led to a solid-state reaction to mainly form the K2MgSiO4 phase in all samples. These results indicate that the K ion can diffuse into the different Mg silicate structures and textures, likely through intercalation in the interlayer space of the different mineral samples followed by dehydroxylation and K2MgSiO4 formation. All the materials showed catalytic activity for the transesterification of soybean oil(1:6 of oil : methanol molar ratio, 5 wt% of catalyst, 60°C). However, the best results were obtained for the antigorite and chrysotile precursors, which are discussed in terms of mineral structure and the more efficient formation of the active phase K2MgSiO4.

Objective： To evaluate the treatment effect of acupuncture on patients with idiopathic trigeminal neuralgia（ITN） by case-control longitudinal blinded study. Methods： Sixty ITN patients and 30 healthy subjects were included. The ITN patients were randomly assigned to acupuncture group（15 cases）, sham-acupuncture group（15 cases） and carbamazepine group（30 cases）, respectively. Clinical orofacial evaluation（including pain intensity and medication doses）, research diagnostic criteria for temporomandibular disorders（RDC/TMD） and Helkimo indexes（for functional evaluation of the masticatory system）, and quantitative sensory testing for sensory thresholds（gustative, olfactory, cold, warm, touch, vibration and superficial and deep pain） were evaluated before treatment, immediately after treatment, and 6 months after treatment. Results： The mean pain intensity by the Visual Analogue Scale only decreased in the acupuncture group at the last evaluation（P=0.012）. Patients in the sham-acupuncture group had an increase in carbamazepine doses according to the prescriptions（P〈0.01）. There was a reduction in secondary myofascial pain and mandibular limitations at the acupuncture and sham-acupuncture groups, however only the acupuncture group kept the changes after 6 months（P〈0.01, P=0.023）. There was a decrease in mechanical thresholds in the acupuncture group（tactile, P〈0.01; vibration, P=0.027） and an increase in deep pain thresholds in both acupuncture and sham-acupuncture groups（P=0.013）. Conclusion： Acupuncture can be an option in the treatment of ITN due to its analgesic effect in both ITN and secondary myofascial pain associated with it.

Nutrient variability and its influence on nitrogen processes in a highly turbid tropical estuary(Bangpakong, Gulf of Thailand)

引用

Journal of Environmental Sciences 2016年第7期28卷 131-142页

作者： Adriano A.Bordalo Kashane Chalermwat Catarina teixeira Laboratory of Hydrobiology and Ecology Institute of Biomedical Sciences University of Porto Centre of Marine and Environmental Research University of Porto department of Aquatic Sciences Burapha University

Estuarine ecosystems in SE Asia have been poorly studied when compared to other tropical environments. Important gaps exist particularly in the understanding of their biogeochemical function and contribution to global change. In this work we looked into N-turnover in the water column and sediments of the Bangpakong estuary（13°N）. A seasonal sampling program was performed along the salinity gradient covering different stretches of the estuary（68 km）.Key physical and chemical characteristics were also monitored in order to unravel possible environmental controls. Results showed the occurrence of active denitrification in sediments（5.7–50.9 nmol N-N2/（cm3·hr））, and water column（3.5–1044 pmol N-N2/（cm3·hr））. No seasonal or spatial variability was detected for denitrification potential in sediment samples. However, in the water column, the denitrification activity peaked during the transition season in the downstream sites coinciding with high turbidity levels. Therefore, in that period of the year, the water column compartment may be an important contributor to nitrate reduction within the estuary. The rather low nitrification rates detected were not always measurable, probably due to the reduced oxygen content and high siltation. This study is one of the few dealing simultaneously with sediments and water column processes in a highly turbid tropical ***, it emerges as a valuable contribution for the understanding of the dynamics of the nitrogen cycle in tropical environments by exploring the role of estuarine N microbial activity in reducing the effects of increased nitrogen loads.

Femoral positioning influences ipsi-and contralateral anterior cruciate ligament rupture following its reconstruction:Systematic review and meta-analysis

引用

World Journal of Orthopedics 2017年第8期8卷 644-650页

AIM To systematically review the incidence of ipsilateral graft re-rupture and contralateral anterior cruciate ligament(ACL) rupture following its reconstruction, with special attention to the femoral drilling technique. METHODS Systematic review and meta-analysis of high-level prospective studies searched in MEDLINE database following PRISMA statement. The rate of ipsilateral graft re-rupture and contralateral rupture in patients submitted to either transtibial(TT) technique(isometric) or anteromedial(AM) technique(anatomic) was compared. RESULTS Eleven studies met the criteria and were included in final analysis. Reconstructions using the AM technique had a similar chance of contralateral ACL rupture when compared to the chance of ipsilateral graft failure(OR = 1.08, P = 0.746). In reconstructions using TT technique, the chance of contralateral ACL rupture was approximately 1.5 times higher than ipsilateral graft failure(OR = 1.49, P = 0.048). Incidence of contralateral lesions were similar among the techniques TT(7.4%) and AM(7.0%)(P = 0.963), but a trend could be noticed with a lower incidence of lesion in the ipsilateral limb when using the TT technique(4.9%) compared to the AM technique(6.5%)(P = 0.081).CONCLUSION ACL reconstruction by TT technique leads to lower incidence of graft re-injury than contralateral ACL lesion. There is no difference between the chance of re-injury after AM technique and the chance of contralateral ACL lesion(native ligament) with either technique.
