Effect Of Phosphogypsum On Properties And Microstructure Of All-Solid-Waste Geopolymer Materials, Zong Wei, Zhang Qixin, Dong Xianzheng, Liu Cheng, Zheng Wuxi Aug 2026

Effect Of Phosphogypsum On Properties And Microstructure Of All-Solid-Waste Geopolymer Materials, Zong Wei, Zhang Qixin, Dong Xianzheng, Liu Cheng, Zheng Wuxi

Journal of China & Foreign Highway

The influence of phosphogypsum dosages on geopolymer performance was investigated to address the high drying shrinkage and slow later-stage strength development of all-solid-waste geopolymer materials. Combined with XRD, SEM, and MIP test results, the effects of phosphogypsum on the properties and microstructure of geopolymer materials were discussed. The results indicate that the incorporation of phosphogypsum reduces the early-stage compressive strength of the geopolymer. However, as the curing age increases, the strength continues to grow and stabilizes by 28 d. Meanwhile, phosphogypsum effectively inhibits early drying shrinkage of geopolymer and induces controlled micro-expansion in the later stage. The reaction of phosphogypsum …

Experimental Study On Physical And Mechanical Properties Of Soft Soil During The Construction Of Wenzhou Shield Tunnels, Zheng Kai, Cao Zhigang, Liu Yaoxing

Journal of China & Foreign Highway

In the subway engineering of soft soil areas, the physical indicators and static-dynamic properties of soft clay are important factors influencing subway design, construction, and project cost. In particular, during subway operation, cyclic dynamic stress induced by running trains acts on the underlying soft soil foundation of the tunnels, thus greatly affecting the operational safety and maintenance of the subway. Based on the Wenzhou Metro M1 Line project, laboratory geotechnical tests and systematic research were carried out on the soft soil through shield tunnels to obtain the basic physical indicators of Wenzhou soft clay, with its consolidation, shear characteristics, and …

Recognition Sight Distance And Minimum Radius Of Vertical Curves At Expressway Tunnel Entrances, Fu Zhipeng, Zhou Shiyang, Pan Binghong, Liu Zhi, Liu Yutong, Liu Yuying

Journal of China & Foreign Highway

Lane changing is generally prohibited and strict speed limits are imposed in expressway tunnels in China. To ensure that drivers can safely and comfortably complete lane changes and speed adjustments before entering a tunnel, horizontal curves should satisfy the tunnel entrance recognition sight distance requirement, and the radii of vertical curves in the longitudinal profile should also satisfy this requirement. If the vertical curve radius of the section before a tunnel entrance is improperly designed, drivers may be unable to recognize the tunnel entrance in time, resulting in rushed lane changes or delayed speed adjustments before entering the tunnel, which …

Trump's Rise: Will China Disrupt The Current Order Or Maintain It?, Ahmad Nurcholis, Wasisto Raharjo Jati

Global: Jurnal Politik Internasional

This paper examines the long-term likelihood of a US-China war, particularly in light of Donald Trump's US presidential win. The two nations have consistently experienced strained relations and intense rivalry, especially throughout the Trump and Biden presidencies. Both leaders are worried about China's growing assertiveness. While these nations are still battling over trade, this situation could easily escalate into an armed conflict later on. Due to China's increasing economic power and America's reduced influence in specific areas, there are predictions of a change in how the world is governed. This paper examines the question of whether China will become a …

Elite Mobilisation And Norm Contestation In A Pluralistic Legal System: A Case Study Of The Gambia, Oumie Njie, Abdou Barrow Aug 2026

Elite Mobilisation And Norm Contestation In A Pluralistic Legal System: A Case Study Of The Gambia, Oumie Njie, Abdou Barrow

Global: Jurnal Politik Internasional

This paper examines elite mobilisation and norm contestation within The Gambia's pluralistic legal framework, encompassing common, customary, and Sharia law, in the context of implementing the Convention on the Rights of the Child (CRC). Despite ratification and domestic legislation, implementation has been significantly challenged by religious leaders and traditional authorities who mobilised resistance against key CRC provisions, including prohibitions on child marriage, child labour, and female genital mutilation (FGM), citing incompatibility with local customs and beliefs. This resistance manifested both implicitly through neglect and explicitly through direct contestation. The paper highlights the tension between civil society organisations and international human …

Relational Reasoning Across Cultures: Consistency And Variation In South Korea, The United States, And China, Alexandra Carstensen, Minju Kim, Youngon Choi, Caren M. Walker Aug 2026

Relational Reasoning Across Cultures: Consistency And Variation In South Korea, The United States, And China, Alexandra Carstensen, Minju Kim, Youngon Choi, Caren M. Walker

Psychology Faculty Articles and Research

Abstract reasoning in early childhood is often described as following a “relational shift,” over which children become increasingly sensitive to relations. However, recent work has challenged the generality of this account, showing that children in the US and China follow distinct trajectories in a relational match-to-sample task. This difference aligns with multiple cultural and linguistic factors implicated in relational reasoning, where the US and China appear at opposite ends of a continuum, focusing on objects (US) versus relations (CN). This raises the possibility that differences in culture and language may shape variation in the development of abstract reasoning. Here, we …

Division of Cardiology Faculty Papers

Traumatic brain injury (TBI) is associated with cardiovascular dysfunction that worsens clinical outcomes, yet the underlying mechanisms are poorly under stood. Clinical studies are limited by heterogeneity, highlighting the need for con trolled experimental models. Controlled cortical impact (CCI) provides precise control of injury severity, and invasive pressure- volume (PV) loop analysis allows detailed hemodynamic assessment. Adult male Wistar rats underwent sham op eration or mild or severe CCI- induced TBI. PV- loop assessment and transtho racic echocardiography were performed at 8 or 24 h after TBI or sham. Serum epinephrine (EPI) and norepinephrine (NE) were quantified by ELISA. At …
