Latin American Policy, Volume 14, Issue 3, Page 388-407, September 2023., 2023 Abstract For years Colombia has been the world's largest coca producer. Its public management of crops for illicit use has swung between eradication, substitution, and, recently legalization. Forced eradication has been shown to be ineffective, and legalization is an incipient option, so the Peace Agreement puts forward substitution as the path to ...

The domestic struggle for traditional medical knowledge rights
Developing World Bioethics, Volume 23, Issue 1, Page 76-87, March 2023., 2023 Abstract In China, the local communities and various ethnic minorities still hold, sustain and develop traditional medicial knowledge (TMK), innovations, and practices within the original communities. TMK also has pharmaceutical option value, which has attracted interests in commercial use of TMK for pharmaceutical innovation in China.

Identifying treponemal disease in early East Asia
American Journal of Biological Anthropology, Volume 178, Issue 3, Page 530-543, July 2022., 2022 Syphilis in China before Vasco da Gama? Abstract Objectives Historic records suggest that a virulent form of treponematosis, sexually transmitted syphilis was introduced to Asia from Europe by the da Gama crew, who landed in India in 1498. Our objective is to assess the gross pathology of human skeletal remains from the Tang dynasty of China to test ...

Seawater desalination by ICP on a new microfluidic chip [PDF]
, 2015 全球淡水资源匮乏受到越来越多的国家的重视，特别是一些水资源短缺的国 家和地区。海水淡化被认为是获得淡水资源的最佳途径之一。现如今海水淡化方 法发展较为迅速，其中主流技术有反渗透法、电渗析法以及蒸馏法等。 虽然上述三种方法发展较早，技术相对成熟，但能耗大、运营成本高，需要 搭建大型配套设备且不便移动，不易全球推广，特别是在欠发达国家。在淡水资 源短缺急剧严重的今天，寻找一种低能耗、成本低、便携式、使用寿命长、易于 市场推广、适合家庭以及个人使用的新型海水淡化装置迫在眉睫，本文研究设计 ...

Synthesis, Separation and characterization of Fullerenes and Their Perchlorinated Fragments [PDF]
, 2000 回顾富勒烯科学的发展历程，不难看出宏量合成在其发展过程中的的重要地位。为了寻找高产率的宏量制备方法，人们进行了广泛的探索和深入的研究。经过多年的努力，富勒烯的合成已经有多种方法，但这些制备方法几乎都难以选择性地合成某一种富勒烯，所以分离仍是一个必要而关键的步骤。在富勒烯科学上，另一个至今仍令人迷惑不解的是富勒烯的形成机理，虽然，象C60、C70等都已经可以方便地商业购得，但其形成过程仍旧是一个值得推敲和争论的问题。人们提出了多种机理来解释富勒烯的形成，但没有一个能解释所有的实验现象 ...

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Shuitu Baochi Xuebao, 2022 为寻求一种能够有效估算宁夏中部干旱带压砂地土壤蒸发量的方法,通过微型蒸渗仪大田试验,研究了0(S1),20%(S2),40%(S3),60%(S4),80%(S5),100%(S6)6种砂土混合比条件下土水蒸发比与表层土壤含水量的关系,并构建了压砂地土壤蒸发量估算模型。结果表明:土水蒸发比随表层土壤含水量呈分阶段变化,即S2~S6为2个阶段,S1为3个阶段,且S1第2,3阶段与其余处理相比存在一定滞后性,表层土壤含水量临界值可用砂土混合比表示为θsi=0.0030si2-0.1705si+14.7340;
