Tick‐Tac‐Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets
Public Health Challenges, Volume 5, Issue 2, June 2026.ABSTRACT Zoonotic diseases account for over ∼60% of infectious diseases and present a significantly growing fatality threat in Africa. Live and wet markets (LWMs) in Africa function as key economic venues that support human livelihoods through social interaction and trade in food stuff, including meat and other animal‐based products.

Development of Planetary Precessional Transmission with Multicouple Gear
, 2013 Some problems of mechanical transmissions can be solved with special effects by developing new types of transmissions based on planetary precessional transmissions with multiple gear, that were developed by the authors. Absolute multiplicity of precessional gear (up to 100 % pairs of teeth simultaneously involved in gearing, compared to 5–7 %—in ...
