Programmable‐Stiffness Tensegrity Continuum Robot for Adaptive Multicurvature On‐Orbit Assembly

open access: yesAdvanced Intelligent Systems, EarlyView.
A bioinspired tensegrity‐based continuum robot (BTCR) with programmable stiffness enables adaptive multicurvature morphing via coordinated intra‐ and intermodule regulation. A unified energy‐based framework predicts self‐equilibrium and deformation for serial modules. Experiments and Simulations demonstrate reconfiguration into hexagonal, circular, and

Sourcing african ivory in chalcolithic Portugal [PDF]

open access: yes, 2009
A recent review of all ivory from excavations in Chalcolithic and Beaker period Iberia shows a marked coastal distribution – which strongly suggests that the material is being brought in by sea.

Fused Deposition Modeling of Industrial Waste LDPE‐Polystyrene Blends: Comparing Low and Medium Melt Flow Index of LDPE Waste

open access: yesJournal of Applied Polymer Science, EarlyView.
Schematic overview of the upcycling of industrial LDPE waste via fused deposition modeling (FDM). ABSTRACT This study explores the potential of additive manufacturing (AM) to upcycle industrial waste low‐density polyethylene (LDPE) by investigating the effect of LDPE waste's melt flow index (MFI) on the printability of LDPE/polystyrene (PS) blends via ...

Preferensi Dan Pendugaan Produktivitas Pakan Alami Populasi Gajah Sumatera (Elephas Maximus Sumatranus Temmick, 1847) Di Hutan Produksi Khusus (Hpkh) Pusat Latihan Gajah (Plg) Sebelat, Bengkulu Utara [PDF]

open access: yes, 2011
The isolation of habitat, shrinking of natural habitat and diminishing of habitat quality have increased conflicts between man and elephant to utilize space and abundance of food.

The Complex Links Between Governance and Biodiversity [PDF]

open access: yes, 2006
We argue that two problems weaken the claims of those who link corruption and the exploitation of natural resources. The first is conceptual. Studies that use national level indicators of corruption fail to note that corruption comes in many forms, at ...

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Why do elephants destroy woodland?

open access: yesPachyderm, 1984
The increase in the number of elephants in some of the conservation areas was followed by a decline in woodland density due to a combination of the destruction by elephants and burning by man.
