Enhancement of mechanical properties of concrete using microwave cured bamboo composites [PDF]

open access: yesArchives of Civil Engineering, 2022
Microwave curing of bamboo fiber increases the physical and mechanical qualities of cement concrete, according to previous studies. However, there are limited research on their endurance when used as an additive in concrete manufacturing to increase ...

Quantitative Characterization of Pore Structure Parameters in Coal Based on Image Processing and SEM Technology

open access: yesEnergies, 2023
The pore structure parameters of coal have an important influence on the exploration and development of coalbed methane. In this study, a series of pore structure parameters, including porosity, pore radius, pore throat radius, pore coordination number ...

Abundance and Equality

open access: yesFrontiers in Research Metrics and Analytics, 2022
The technology driven post-scarcity society is upon us. Ubiquitous technologies are eradicating scarcity in many industries. These macroscopic system trends are causing our economy to transition from relative scarcity to relative abundance. For many people in the world however, in both developed, developing, and underdeveloped countries, the notion of ...

Associations of 16-Year Population Dynamics in Range-Expanding Moths with Temperature and Years since Establishment

open access: yesInsects, 2023
Parallel to the widespread decline of plants and animals, there is also an ongoing expansion of many species, which is especially pronounced in certain taxonomic groups and in northern latitudes. In order to inform an improved understanding of population

Interannual Abundance Fluctuations of Two Oceanic Squids in the Pacific Ocean Can Be Evaluated Through Their Habitat Temperature Variabilities

open access: yesFrontiers in Marine Science, 2021
Neon flying squid (Ommastrephes bartramii) and jumbo flying squid (Dosidicus gigas) are two commercially essential oceanic squids in the Pacific Ocean.

Reducing bias in density estimates for unmarked populations that exhibit reactive behaviour towards camera traps

open access: yesMethods in Ecology and Evolution, 2023
Density estimates guide wildlife management, and camera traps are commonly used to estimate sizes of unmarked populations. Unfortunately, animals often alter their natural behaviour in the presence of camera traps, which may bias subsequent density ...

Consumptive and nonconsumptive effects of omnivorous tadpoles on aquatic invertebrate communities

open access: yesEcosphere, 2023
Consumptive effects (CEs) of predation have been well‐studied in most aquatic systems, but nonconsumptive effects (NCEs) on prey have only recently received limited attention.

Imperfect Estimation of Lepeophtheirus salmonis Abundance and Its Impact on Salmon Lice Treatment on Atlantic Salmon Farms

open access: yesFrontiers in Marine Science, 2021
Accurate monitoring of sea lice levels on salmon farms is critical to the efficient management of louse infestation, as decisions around whether and when to apply treatment depend on an estimation of abundance.

On Generalised Abundance, II [PDF]

open access: yesPeking Mathematical Journal, 2019
The goal of this paper is to make a striking connection between several central conjectures in algebraic geometry: the Nonvanishing Conjecture, the Abundance Conjecture and the Semiampleness Conjecture for nef line bundles on K -trivial varieties.
