Noise from firearms is well known to be harmful to human hearing. This problem has been addressed by various military units through the use of muzzle suppressors. However, as suppressor technology has advanced, shooters report hearing the mechanical action of gas-operated semi-automatic rifles (ArmaLite Rifle Model 15 style aka AR-15) as being louder than the suppressed muzzle noise.

- - The study aimed to analyze how maintenance energy needs in limit-fed Angus cows relate to energy used for building maternal tissue and milk production, and how this retained energy impacts forage intake during the dry period.
- - Twenty-four Angus cows were monitored over a 79-day late lactation phase, with precise adjustments made to their daily feed intake based on changes in body weight, and milk production and composition were measured periodically.
- - Findings indicated that maintenance energy for lactation was lower than expected, suggesting that as cows retain more energy (gain less weight and produce more milk), their energy requirements for maintenance decrease, differing from earlier beliefs about the relationship between milk yield and maintenance needs.
The objective of this study was to examine the effects of diet energy density on ranking for dry matter intake (DMI), residual feed intake (RFI), and greenhouse gas emissions. Forty-two mature, gestating Angus cows (600 ± 69 kg body weight [BW]; body condition score [BCS] 5.3 ± 1.

The release of microbial methane from tailings emplaced within oil sands pit lakes, and its subsequent microbial oxidation, could inhibit the development of persistent oxygen concentrations within the water column, which are critical to the success of this reclamation approach. Here, we describe the results of a four-year (2015-2018) chemical and isotopic (δC) investigation into the dynamics of microbial methane cycling within Base Mine Lake (BML), the first full-scale pit lake commissioned in the AOSR.
