能量与物质的先验图像和经验图像
----
纪念中国数学家吴学谋教授逝世四周年
科孝文
摘要：本文是纪念中国数学家吴学谋教授逝世四周年，以解读《泛系:万悖痴梦》，其中《泛系史记》《泛系方程》由吴学谋教授编著、中国科技大学出版社2005年出版的学术著作；该书虽属于泛系理论研究的专业书籍；吴学谋教授还去华中科技大学办过讲座，但也引起争议----什么是能量与物质的先验图像和经验图像？

评《组成论》中的“
张学文悖论”
----三旋环量子双曲率的不确定性研究
王德奎
摘要：张学文教授在《组成论》一书中提出的最复杂原理，有些情形类似一个悖论，实际是个重大发现：即最大复杂度“熵”与热力学“熵”和信息“熵”都能在“不确定性原理”下统一，这是三旋环量子双曲率的不确定性，对《组成论》个体单曲率的决定论的深化。

雷元星科学社会波澜探秘
柯猜----一块永恒的金芯片
长江康
摘要：读2022年出版的美国普林斯顿大学理论物理学家戴森教授的《宇宙波澜----科技与人类前途的自省》一书，使我们想到1996年在四川省委宣传部退休后，发表了三百多万字的学术研究与科普创作的雷元星教授的事迹，他的科学社会波澜探秘，能否揭示科技与人类前途的自省？

Abstract:
This study
evaluated noise levels in selected sawmills in Owerri
Metropolis, Nigeria. The study aims to measure and
analyze noise intensity and frequency, assess potential
health risks, and recommend mitigation strategies. A
purposive sampling technique was used to select 40
respondents. A semi-structured questionnaire was used to
collate information from sawmill workers using the Kobo
Collect mobile application. Information gathered
captured the perceptions of noise exposure and its
impacts on health (symptoms of hearing loss, stress, and
other related health issues) of the workers.
Noise
measurements were taken using sound level meters at
various distances (of 1, 5 and 9 meters) within the
sawmills during peak operational hours (2 – 4 pm West
African Time) to ensure accuracy and representatives of
typical working conditions. The study revealed that
62.5% of workers were between 30-49 years old, and 62.5%
were male. Noise levels exceeded recommended safety
limits, posing serious threats to workers' hearing and
overall health. The Umuonyeali sawmill recorded an
average of 85.4889 dB for the Circular saw machine,
while the Naze sawmill recorded 94.0889 dB. The Spindle
moulder machine recorded 94.2556 dB at Umuonyeali and
90.7556 dB at Naze. A significant difference in noise
levels was found between the two sawmills (p<0.1). To
mitigate these risks, the study recommends introducing
work rotation schedules, conducting regular hearing
tests, and installing mass-loaded vinyl or heavy
materials on roofs to reduce noise levels. These
measures can help protect workers' hearing and overall
health, ensuring a safer working environment in the
sawmills.
