Microwave deicing properties and carbon emissions assessment of asphalt mixtures containing steel slag towards resource conservation and waste reuse
Full text linkFunding Information: This work was supported by the National & Local Joint Engineering Research Center of Transportation and Civil Engineering Materials, Chongqing Jiaotong University (Grant number: TCEM-2023-02 ). Fan Zhang would like to thank Ruimeng Song (Chang'a University, China) for her assistance on laboratory experiments. Publisher Copyright: © 2023 The AuthorsA large amount of solid waste, such as steel slag (SS), is generated annually. At the same time, the shortage of road construction materials is becoming a concern. In this study, to recycle and reuse SS as a substitute for natural aggregates to achieve resource conservation and sustainable development of roads were conducted. First, the electromagnetic performance of SS was explored to evaluate its wave-absorbing properties. Next, the effect of different SS contents on heating properties, surface temperature, heating uniformity, and ice melting time (IMT) were investigated. Finally, the carbon emissions assessment (CEA) of conventional asphalt mixture (CAM) and steel slag asphalt mixture (SSAM) was compared. Results indicated that SS has ferromagnetic behavior and higher electromagnetic parameters, showing better wave-absorbing properties than limestone. There were three stages during microwave heating (MH): ice melting, moisture emitting, and stabilization. In addition, heating uniformity tends to be poor with the increase of SS, and samples with 100 % content of SS have the highest standard deviation of 21.04 °C and 20.77 °C after 270 s at −10 °C and − 20 °C. Samples containing 50 % SS have the best microwave deicing properties, which can reduce the IMT by 28.57 % to 46.18 % at different initial freezing temperatures and ice thickness compared to CAM. Furthermore, CEA revealed that CAM and SSAM's carbon emissions over road construction's life cycle are similar (around 27,000 kg) and originate mainly from the mixing and raw material extraction phases. However, SSAM leads to better environmental and economic benefits and provides an exemplary resource conservation and waste reuse solution.Peer reviewe

RIC-HSCT for MF/SS
Full text linkAdvanced-stage mycosis fungoides and Sezary syndrome (MF/SS) have a poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT), particularly using a reduced-intensity conditioning (RIC) regimen, is a promising treatment for advanced-stage MF/SS. We performed RIC-HSCT in nine patients with advanced MF/SS. With a median follow-up period of 954days after HSCT, the estimated 3-year overall survival was 85.7% (95% confidence interval, 33.4-97.9%) with no non-relapse mortality. Five patients relapsed after RIC-HSCT; however, in four patients whose relapse was detected only from the skin, persistent complete response was achieved in one patient, and the disease was manageable in other three patients by the tapering of immunosuppressants and donor lymphocyte infusion, suggesting that graft-versus-lymphoma effect and "down-staging" effect from advanced stage to early stage by HSCT improve the prognosis of advanced-stage MF/SS. These results suggest that RIC-HSCT is an effective treatment for advanced MF/SS

No full textSubmarine features of modern open-sea fan deltas, Huon Peninsula, Papua New Guinea
No full textA series of fan deltas has been delineated in water depths between 300 and 1900 m along the 75 km shelf and slope of the northern Huon Gulf, Papua New Guinea using the HAWAII MR1 side-scan system. Comparison of these fan deltas suggests that submarine slope profiles and feeder systems (i.e., type and size) are the most important factors controlling the construction and the geometry of the submarine fan deltas. Fan deltas are fully developed only at large rivers in areas with a SS-shaped slope profile.
Six zones are recognised on the SS-profiled fan delta surface based on the submarine topographic characteristics, dominant acoustic facies and slopes. The zonation differs from that of Prior and Bornhold (1989) from fan deltas in a British Columbian fjord in terms of magnitude, slope profiles and submarine channelling patterns. The Huon fan deltas represent larger, more dynamic, deep-water delta systems with individual fan deltas up to 200 km2. The main parts of the Huon fan deltas are deposited below 500 m, 5 km from river mouths. Large quantities of coarse-grained sediments are found in water depths over 1400 m, 13 km from river mouths. The relief of the interfingered narrow ridges and gullies in Zone 3 is up to 100 m. Zone 6 has a slope gradient of 4.4°, much steeper than Zone 5 (1.5°).
The Huon fan deltas can not be easily fitted into any of the existing classification. They warrant a comparative study of fan deltas with similar feeder systems but different slope profiles, and with similar slope profiles but different feeder systems in the same basin regime. Delta classification and nomenclature needs to reflect seven attributes: feeder system, basin dynamics, water depth (depth ratio), slope profile, dominant slope process, delta-front grain size and geometry
