墨西哥西南部加利斯科地块记录了叠加在聚敛大陆边缘上大陆裂谷化的初始阶段。在地块内北北西走向的地堑体系中,上新世一第四纪喷发作用形成了各种类型的熔岩,色括云煌岩、白榴岩、橄榄粒玄岩和安山岩。散见其中的是好几种在组成上类似于洋岛熔岩的玄武质盾状火山。在加利福尼亚湾较多见的中新世盆岭仲展作用证据,只能在沿加利斯科地块北部边缘可以见到。在中新世晚期大体积的碱性玄武岩沿这一北部边缘的好几处喷发。我们认为加利斯科地块有所限制的范围内,上新世一第四纪的拉张作用以及火山作用都是复杂板块边界重组的结果,并引起地块从黑西哥大陆裂解出去。

Science Societies’ Climate Statements: Some Concerns

引用

Open Journal of Applied Sciences 2024年第6期14卷 1573-1603页

作者： wallace Manheimer United States Naval Research Laboratory (Retired) Washington USA

The assertion that a climate crisis is rapidly approaching due to excess carbon dioxide (CO2) in the atmosphere is said to be based on science. This science is summarized in the statements of the major scientific societies. These statements, have motivated, governments, the media, and much of the public to commit to abandoning fossil, i.e. going to “net zero” at some time in the not-so-distant future, perhaps by 2050, 26 years from now. The claims of these scientific societies clearly have a profound impact on the government, the media and the public, and therefore the scientific basis for these claims needs to be frequently and rigorously reexamined by the societies, and scrutinized by the public. This paper illustrates some serious concerns regarding the claims of these societies. It is not difficult to question these claims by comparing them with actual data from well-established organizations such as NOAA and NASA. Furthermore, the claims seem to go against such well-established scientific laws as the Stefan Boltzman radiation law, and le Chatelier’s principle. If the statements of the societies overstate the danger, or are even incorrect, they may be motivating the United States, the western world, or even the whole world to make an enormously expensive and unnecessary transition to an energy infrastructure that is more expensive, less reliable, and more environmentally damaging than the one we have today. This article suggests that these scientific societies reexamine their climate statements with the goal of making them more moderate and more scientifically correct.

Fusion: It’s Time to Color outside the Lines

引用

Open Journal of Applied Sciences 2024年第3期14卷 740-800页

作者： wallace Manheimer US Naval Research Laboratory (Retired) Washington DC USA

There has been some good news, and some bad news in the controlled fusion community recently. The good news is that the Lawrence Livermore National Laboratory (LLNL) has recently produced a burning plasma. It succeeded on several of its shots where ~1.5 - 2 megajoules from its laser (National Ignition Facility, or NIF) has generated ~1.3 - 3 megajoules of fusion products. The highest ratio of fusion energy to laser energy it achieved, defined as its Q, was 1.5 at the time of this writing. While LLNL is sponsored by nuclear stockpile stewardship, this author sees a likely path from their result to fusion for energy for the world, a path using a very different laser and a very different target configuration. The bad news is that the International Tokamak Experimental Reactor (ITER) has continued to stumble on more and more delays and cost overruns, as its capital cost has mushroomed from ~$5 billion to ~ $25 B. This paper argues that the American fusion effort, for energy for the civilian economy, should switch its emphasis not only from magnetic fusion to inertial fusion but should also take much more seriously fusion breeding. Over the next few decades, the world might well be setting up more and more thermal nuclear reactors, and these might need fuel which only fusion breeders can supply. In other words, fusion should begin to color outside the lines.
