Tsavo Trust is an action‐orientated, field‐based, not‐for‐profit conservation organization headquartered in Tsavo, Kenya. In association with Kenya Wildlife Service and other partners, Tsavo Trust utilizes a unique strategy to work on direct wildlife‐conservation projects. Tsavo Trust also engages with specific local communities in the stewardship of conservancies, in order to encourage participation in conservation activities that benefit the marginalized people who live on the border of the formal Protected Area. Tsavo Trust recognizes the importance of a holistic approach to biodiversity conservation, using a combination of professional wildlife conservation activities, grass‐roots community engagement, valued partnerships and committed supporters to create a virtuous circle for the protection of Tsavo. The mission is to conserve the vast wilderness of the Tsavo Conservation Area, which encompasses Kenya's biggest Protected Area, and is home to Kenya's largest elephant population, including several iconic ‘Tuskers’, and numerous high‐value species. Tsavo Conservation Area is one of the few truly wild places with significant wildlife left in Africa. This national heritage is under threat and faces multiple challenges, including wildlife crime, climate change and habitat loss. At the time of writing, the Tsavo elephant population contains eight bull ‘Tuskers’ and five iconic cow ‘Tuskers’, as well as c. 26 younger bulls that may emerge as ‘Tuskers’ in the next 5 years. Tsavo Trust's work focuses on four core programmes: ‘Wildlife Conservation Program: Big Tusker Project’, ‘Community Conservancy Program’, ‘Animal Welfare Program’ and ‘Conservation Partnerships’. Through the Big Tusker Project, Tsavo Trust, in partnership with Kenya Wildlife Service, provides extra protection for the last ‘Super Tuskers’ of Tsavo using aerial surveillance and mobile ground‐based units.

A scheme for an electrical classification of the solution concentration of bioconjugated colloidal gold particles is presented. It is based on the immobilization of the particles in the gap of microstructured electrodes, followed by a metal enhancement step and electrical measurements. The surface density of particles depends on the solution concentrations, and the metal enhancement classifies this density by yielding conductive surfaces only for densities above a threshold. Size enhancement ratios of up to 10 were observed for 30 nm particles and could be controlled by the incubation time.

We have studied the processpp???+X at GeV in the central rapidity region. We report a positive signal at 96% C.L., a ratio ??/e+e-=4.0±3.0 when the transverse momentum of each photon is above 2 GeV/c, and a cross-sectionds/dydM??=(5.5±2.7)×10-34 cm2/GeV when |y|<0.5,4??<6 GeV.

Using the tip of a scanning tunneling microscope thin films of the copolymer poly(vinylidenefluoride-trifluoroethylene) have been locally polarized. The size of the poled area could be reduced to 2·10-14 m2. Switching times down to 100 ns have been found.
