Arisaema siahaense sp. nov. (Araceae) from India

Nordic Journal of Botany, EarlyView.
A new species of Arisaema Mart. (Araceae) belonging to sect. Fimbriata is described and illustrated here from the Siaha District, Mizoram, India. This new species is characterized by an evergreen, dioecious herbaceous habit, up to 1.08 m high, having a subglobose tuber, with a solitary trifoliate leaf.

Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

Sustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

Charring rate for fire exposed X-Lam [PDF]

, 2017
Design of timber structures has been outlined in Eurocode 5. Notional charring rate for softwood and hardwood timber is given. For the performance of X-LAM panels in fire, only little information on charring is available and whether the fire behaviour of

Incremental upper bound modeling of concrete failures in timber‐concrete notched connections

Structural Concrete, EarlyView.
Abstract This paper introduces a novel theoretical framework for developing incremental upper bound solutions, which is applied to predict the response of two local concrete failures in timber‐concrete composite (TCC) decks with notched connections. The new approach enables a prediction of the capacity at the onset of failure as well as the entire post‐

Method for calculating cross laminated timber panels

Вестник гражданских инженеров, 2020
Cross-laminated timber (CLT) panels are widely used in the construction of buildings and structures abroad. Regulatory documentation in the Russian Federation does not contain provisions for calculating such structures. The paper considers the method of calculating the floor slab made of CLT panel using the Euler Bernoulli beam theory.

Structural response of cross-laminated timber compression elements exposed to fire [PDF]

, 2017
A set of novel structural fire tests on axially loaded cross-laminated timber (CLT) compression elements (walls), locally exposed to thermal radiation sufficient to cause sustained flaming combustion, are presented and discussed.

Elevation reverses the effects of forest structure on folivory and leaf asymmetry

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Centuries of timber production have homogenized many forests by reducing variation in canopy density and deadwood availability, with far‐reaching consequences for biodiversity and trophic interactions.
