Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 2,   Pages 219-230 doi: 10.1007/s11783-012-0469-9

Abstract: Nan), a selected typical pollution-safe cultivar (Cd-PSC), and cv. Pennongjianyexian (cv.Pen), a selected typical non-Cd-PSC, under different Cd exposure conditions were compared.The results indicated that amaranth is capable of enduring high level of Cd pollution when grown as vegetableTherefore, adopting Cd-PSC strategy would help reducing the risk of Cd pollution in amaranth.Nan was identified as a Cd-PSC and recommended to be applied production practice.

Urban constructed wetlands: Assessing ecosystem services and disservices for safe, resilient, and sustainable

Frontiers of Engineering Management 2023, Volume 10, Issue 4,   Pages 582-596 doi: 10.1007/s42524-023-0268-y

Abstract: Climate change and rapid urbanization are pressing environmental and social concerns, with approximately 56% of the global population living in urban areas. This number is expected to rise to 68% by 2050, leading to the expansion of cities and encroachment upon natural areas, including wetlands, causing their degradation and fragmentation. To mitigate these challenges, green and blue infrastructures (GBIs), such as constructed wetlands, have been proposed to emulate and replace the functions of natural wetlands. This study evaluates the potential of eight constructed wetlands near Beijing, China, focusing on their ecosystem services (ESs), cost savings related to human health, growing/maintenance expenses, and disservices using an emergy-based assessment procedure. The results indicate that all constructed wetlands effectively purify wastewater, reducing nutrient concentrations (e.g., total nitrogen, total phosphorus, and total suspended solids). Among the studied wetlands, the integrated vertical subsurface flow constructed wetland (CW-4) demonstrates the highest wastewater purification capability (1.63E+14 sej/m2/yr) compared to other types (6.78E+13 and 2.08E+13 sej/m2/yr). Additionally, constructed wetlands contribute to flood mitigation, groundwater recharge, wildlife habitat protection, and carbon sequestration, resembling the functions of natural wetlands. However, the implementation of constructed wetlands in cities is not without challenges, including greenhouse gas emissions, green waste management, mosquito issues, and disturbances in the surrounding urban areas, negatively impacting residents. The ternary phase diagram reveals that all constructed wetlands provide more benefits than costs and impacts. CW-4 shows the highest benefit‒cost ratio, reaching 50%, while free water surface constructed wetland (CW-3) exhibits the lowest benefits (approximately 38%), higher impacts (approximately 25%), and lower costs (approximately 37%) compared to other wetlands. The study advocates the use of an emergy approach as a reliable method to assess the quality of constructed wetlands, providing valuable insights for policymakers in selecting suitable constructed wetlands for effective urban ecological management.

Major Technologies for Safe Construction of High Earth-Rockfill Dams

Hongqi Ma, Fudong Chi

Engineering 2016, Volume 2, Issue 4,   Pages 498-509 doi: 10.1016/J.ENG.2016.04.001

Abstract:

The earth-rockfill dam is one of the primary dam types in the selection of high dams to be constructed in Western China, since it is characterized by favorable adaptability of the dam foundation; full utilization of local earth, rock, and building-excavated materials; low construction cost; and low cement consumption. Many major technical issues regarding earth-rockfill dams with a height of over 250 m were studied and solved successfully in the construction of the 261.5 m Nuozhadu earth core rockfill dam. This paper describes research achievements and basic conclusions; systematically summarizes the accumulated experiences from the construction of the Nuozhadu Dam and other high earth-rockfill dams; and discusses major technical issues, such as deformation control, seepage control, dam slope stability, safety and control of flood discharging, safety and quality control of dam construction, safety assessments, early warning, and other key technical difficulties. This study also provides a reference and technological support for the future construction of 300 m high earth-rockfill dams.

Homoharringtonine is a safe and effective substitute for anthracyclines in children younger than 2 years

Frontiers of Medicine 2019, Volume 13, Issue 3,   Pages 378-387 doi: 10.1007/s11684-018-0658-4

Abstract: Homoharringtonine (HHT), a plant alkaloid from , exhibits a unique anticancer mechanism and has been widely used in China to treat patients with acute myeloid leukemia (AML) since the 1970s. Trial SCMC-AML-2009 presented herein was a randomized clinical study designed based on our previous findings that pediatric AML patients younger than two years old may benefit from HHT-containing chemotherapy regimens. Patients randomized to arm A were treated with a standard chemotherapy regimen comprising mainly of anthracyclines and cytarabine (Ara-C), whereas patients in arm B were treated with HHT-containing regimens in which anthracyclines in all but the initial induction therapy were replaced by HHT. From February 2009 to November 2015, 59 patients less than 2 years old with AML (other than acute promyelocytic leukemia) were recruited. A total of 42 patients achieved a morphologic complete remission (CR) after the first course, with similar rates in both arms (70.6% vs.72.0%). At the end of the follow-up period, 40 patients remained in CR and 5 patients underwent hematopoietic stem cell transplantation in CR, which could not be considered as events but censors. The 5-year event-free survival (EFS) was 60.2%±9.6% for arm A and 88.0%±6.5% for arm B ( =0.024). Patients in arm B experienced shorter durations of leukopenia, neutropenia, and thrombocytopenia and had a lower risk of infection during consolidation chemotherapy with high-dosage Ara-C. Consequently, the homoharringtonine-based regimen achieved excellent EFS and alleviated hematologic toxicity for children aged younger than 2 years with AML compared with the anthracycline-based regimen.

Approaches to achieve high grain yield and high resource use efficiency in rice

Jianchang YANG

Frontiers of Agricultural Science and Engineering 2015, Volume 2, Issue 2,   Pages 115-123 doi: 10.15302/J-FASE-2015055

Abstract: This article discusses approaches to simultaneously increase grain yield and resource use efficiency in rice. Breeding nitrogen efficient cultivars without sacrificing rice yield potential, improving grain fill in later-flowering inferior spikelets and enhancing harvest index are three important approaches to achieving the dual goal of high grain yield and high resource use efficiency. Deeper root distribution and higher leaf photosynthetic N use efficiency at lower N rates could be used as selection criteria to develop N-efficient cultivars. Enhancing sink activity through increasing sugar-spikelet ratio at the heading time and enhancing the conversion efficiency from sucrose to starch though increasing the ratio of abscisic acid to ethylene in grains during grain fill could effectively improve grain fill in inferior spikelets. Several practices, such as post-anthesis controlled soil drying, an alternate wetting and moderate soil drying regime during the whole growing season, and non-flooded straw mulching cultivation, could substantially increase grain yield and water use efficiency, mainly via enhanced remobilization of stored carbon from vegetative tissues to grains and improved harvest index. Further research is needed to understand synergistic interaction between water and N on crop and soil and the mechanism underlying high resource use efficiency in high-yielding rice.
