Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States. [PDF]
Conserv BiolAbstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

Feeding the future in Ghana: Gender inequality, poverty, and food insecurity
World Medical &Health Policy, Volume 15, Issue 4, Page 638-671, December 2023., 2023 Abstract As women's empowerment is critical for the adoption of agricultural technologies by farmers, some governments have over the last three decades adopted a gender equality approach to food security. In Ghana, women play a vital role as farmers and food processors, which means they impact household nutrition in important ways.

Veterinary Dermatology, Volume 33, Issue 6, Page 523-526, December 2022., 2022 Background: There is increasing evidence of cross‐reactivity between allergens of close or distant species. The A‐RISC (Allergens'–Relative Identity, Similarity and Cross‐reactivity) index helps evaluate the risk of theoretical cross‐reactivity between proteins of the same family among different species.

Material and Energy Conversion of Integrated 100,t/a-Scale Bio-Jet Fuel-Range Hydrocarbon Production System via Aqueous Conversion of Biomass [PDF]
, 2017 以农业废弃物生物质为原料，利用水相转化技术，进行了百吨/年规模生物航油类烃(C8~C15)合成试运行.过程中采用两步酸解法分别将玉米秸秆中半纤维素和纤维素转化为糠醛和乙酰丙酸，作为生物质基平台化合物.在碱性条件下糠醛与乙酰丙酸经Aldol缩合反应实现碳链增长，生成的长链含氧中间体经过低温预加氢、高温加氢脱氧及精制，生成C8~C15范围内液态烃，可作为生物航油组分.以试运行实验结果为基础，进行了过程的物质与能量转化分析.结果表明，该路线获得液态烃类的基本性质满足合成航油ASTM-7566标准要求 ...
