2024-08-01
(Press-News.org)
The field of bridge engineering is witnessing a transformative era, as China leads the way with its recent advancements in constructing large-span arch bridges. Jielian Zheng, the member of the Chinese Academy of Engineering from Guangxi University, has authored a research article in Engineering, titled “Recent Construction Technology Innovations and Practices for Large-Span Arch Bridges in China.” The article elucidates the significant strides made in the construction of concrete-filled steel tubular (CFST) and steel-reinforced concrete (SRC) arch bridges, which have been propelled by technological breakthroughs over the past three decades.
Academician Zheng’s research underscores the pivotal role of innovation in enhancing the efficiency, safety, and economy of arch bridge construction. The article details the construction of two landmark bridges—the Pingnan Third Bridge with a 560-meter span and the Tian’e Longtan Bridge, which boasts an impressive 600-meter span. These projects exemplify the cutting-edge techniques that have been developed and implemented under Zheng’s guidance, marking a new chapter in the history of bridge engineering.
The technological innovations highlighted in the article include cable-stayed fastening-hanging cantilevered assembly methods for CFST bridges, and for SRC bridges, the development of new encasing concrete materials and advanced pouring techniques. These innovations have not only addressed the inherent challenges associated with arch bridge construction but have also significantly reduced construction risks and costs.
China’s achievements in arch bridge construction are a testament to the nation’s unwavering commitment to pushing the boundaries of infrastructure development. The progress made in this field has set a new benchmark for global bridge engineering practices, inspiring engineers worldwide to pursue excellence in their craft.
The article concludes by outlining future research directions and development opportunities for CFST and SRC arch bridges. It emphasizes the need for continuous innovation and the importance of addressing new challenges as they arise in the field of bridge construction.
China’s progress in arch bridge construction is a shining example of how engineering innovation can redefine the limits of infrastructure development. This research article is showcasing China’s leadership in the field of bridge construction and the potential for further advancements in the future.

(WASHINGTON, August 1, 2024) — In a year-long pilot program, external mentorship increased confidence, furthered career development, and facilitated networking opportunities for trainees in classical hematology, according to a study published in Blood Advances.
Classical hematology, the study of non-cancerous blood disorders such as sickle cell anemia and thrombotic and hemorrhagic disorders, is projected to face a significant workforce shortage in the coming years. The American Society of Hematology’s (ASH) previous surveys of hematology/oncology program ...

Fukuoka, Japan – Researchers from Kyushu University have discovered that blowflies, a family of flies strongly attracted to decaying flesh and feces, are carrying the bird flu virus in southern Japan. Their findings, published in Scientific Reports, introduce a potential new route of transmission for bird flu and highlight the need to develop new countermeasures to prevent and control the disease in poultry farms.
Since 2020, bird flu has been spreading rapidly around the globe, leading to the death of millions of wild birds and the culling ...

In a recent study published in Engineering, a team of Chinese researchers has uncovered a startling correlation between stock market volatility and the risk of major adverse cardiovascular events (MACEs) and suicide. The research, which analyzed over 12 million deaths across China from 2013 to 2019, provides compelling evidence that the psychological stress induced by stock market fluctuations has severe and immediate health implications.
The study, titled “Stock Volatility Increases the Mortality Risk of Major Adverse Cardiovascular Events and Suicide: A Case-Crossover Study of 12 Million Deaths,” is a wake-up call for investors, ...

Judging how happy you are could backfire and negatively impact life satisfaction and psychological well-being, according to research published by the American Psychological Association.
In three experiments comprising more than 1,800 participants, researchers found that having concerns or judgments about one’s own level of happiness were associated with lower well-being, due in part to greater negativity and disappointment about positive events.
The research was published in the journal Emotion.
Thinking too much about one’s own level of happiness could be related to fears about not measuring up or not being as happy as other people, said lead researcher Felicia ...

In the United States and worldwide, cardiovascular disease is the leading avoidable cause of premature death and disability. Primarily heart attacks and stroke, cardiovascular disease accounts for more than 900,000 annual deaths nationally and about 10 million deaths globally.
Uncontrolled hypertension or high blood pressure is a major risk factor for stroke and heart attacks. Prevention and management of cardiovascular disease involves therapeutic lifestyle changes such as diet and exercise and adjunctive drug therapies of proven benefit.

Researchers including those from the University of Tokyo’s Graduate School of Pharmaceutical Sciences transferred genes from simple organisms capable of regenerating their bodies into common fruit flies, more complex animals that cannot. They found the transferred gene suppressed an age-related intestinal issue in the flies. Their results suggest studying genes specific to animals with high regenerative capability may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan ...

Plant diseases pose significant challenges to agricultural productivity, presenting formidable hurdles that require urgent attention. Left unchecked, these diseases can spread rapidly, inflicting widespread damage on crops and leading to reduced yields and substantial economic losses. Therefore, accurately identifying the pathogens responsible for these diseases is crucial. This identification allows for targeted interventions that minimize risks and effectively mitigate the agricultural impacts.
Xanthomonas species are notorious plant pathogens that affect a broad spectrum of hosts, including key crops like rice, wheat, and tomatoes. These pathogens augment ...

When developing new drugs, understanding their effects on ion channels in the body, such as the human ether-a-go-go-related gene (hERG) ion channel found in neurons and heart muscle cells, is critical. Blocking hERG channels can disrupt normal heart rhythm, potentially leading to a fatal condition known as torsade de pointes. Current methods for assessing these effects typically involve invasive procedures like patch-clamp techniques or fluorescence microscopy. These methods alter cell properties and may affect measurement accuracy, requiring specialized equipment ...
