BS 1088. In materials, BS 1088 is the British Standard specification for marine plywood that applies to plywood produced with untreated tropical hardwood veneers that have a set level of resistance to fungal attack. The plies are bonded with Weather Boil Proof (WBP) glue. [1]
Increasing protection can be applied (in increasing order of attack and treatment) for: exposure to the atmosphere, implantation within soil, or insertion into a marine environment. In the last decade concerns were raised that the chemicals may leach from the wood into surrounding soil , resulting in concentrations higher than naturally ...
Natural durability is the inherent capability of wood to tolerate and resist fungal decay and insect attacks, such as woodboring beetles and termites, and marine organisms. [45] This protective feature is attributable to specific biological compounds, called extractives that are toxic to wood-destroying organisms.
The Lambda variant, also known as lineage C.37, is a variant of SARS-CoV-2, the virus that causes COVID-19. [1] It was first detected in Peru in August 2020. [2] On 14 June 2021, the World Health Organization (WHO) named it Lambda variant [1] and designated it as a variant of interest. [3] On 16 March 2022, the WHO has de-escalated the Lambda ...
SARS-related coronavirus is a member of the genus Betacoronavirus (group 2) and monotypic of the subgenus Sarbecovirus (subgroup B). [13] Sarbecoviruses, unlike embecoviruses or alphacoronaviruses, have only one papain-like proteinase (PLpro) instead of two in the open reading frame ORF1ab. [14] SARSr-CoV was determined to be an early split-off ...
Spike glycoprotein is a class I fusion protein that contains two regions, known as S1 and S2, responsible for these two functions. The S1 region contains the receptor-binding domain that binds to receptors on the cell surface. Coronaviruses use a very diverse range of receptors; SARS-CoV (which causes SARS) and SARS-CoV-2 (which causes COVID-19 ...
A small number of pet animals have been infected. There have been several cases of zoo animals testing positive for the virus, and some became sick. The virus has also been detected in wild animals. Cats, dogs, ferrets, fruit bats, gorillas, pangolins, hamsters, mink, sea otters, pumas, snow leopards, tigers, lions, hyenas, hippos, tree shrews ...
Characteristic thin dark reddish brown glue joints laminating the plies together of this exterior grade plywood. Resorcinol glue, also known as resorcinol- formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light. [1][2] The adhesive, introduced in 1943 ...
