Five transport media were selected for testing, in vitro, the survival of a pure strain of Prevotella intermedia (Bacteroides intermedius) for 6, 24, and 72 hours. Two were non-nutrient transport media (RTF and VMG IV). The three others (TG, PY, PYG) were nutrient media. An increase in the transport time, and manipulations in an aerobic atmosphere compromised the survival of the bacteria. PY ensured good survival of the bacteria. RTF seems to be the best medium for the transport of P. intermedia, when quantitative analysis is required.

Understanding energy transport in semiconductors is critical for the design of electronic and optoelectronic devices. Semiconductor material properties, such as charge carrier mobility or diffusion length, are commonly measured in bulk crystals and determined using models that describe transport behavior in homogeneous media, where structural boundary effects are minimal. However, most emerging semiconductors exhibit nano- and microscale heterogeneity.

Erhai Lake, a vital drinking water source for Dali, a highland agricultural city, faces potential contamination from pesticide residues, yet limited studies have assessed their distribution and impacts. This study investigates the occurrence, transport, partitioning, and ecological risks of pesticides in the lake's dissolved phase (DP), suspended particulate matter (SPM), and sediment (SD) samples collected from 22 sites across different seasons. The results showed significant temporal variations across different media, with spatial variations driven by crop-related patterns.

Background: Children with disabilities encounter obstacles attaining basic education. Significantly, previous studies on South Africa have shown that up to 70% of the children with disabilities are out of school. Despite efforts to support inclusive education through White Paper 6 policy, the deployment of resources and transformation of the education sector has been a slower process.

Carrot callus grown on a medium with increased nitrogen have reduced carotenoid accumulation, changed gene expression, high amount of vesicular plastids and altered cell wall composition. Carotenoid biosynthesis is vital for plant development and quality, yet its regulation under varying nutrient conditions remains unclear. To explore the effects of nitrogen (N) availability, we used carrot (Daucus carota L.

In-space biomanufacturing provides a sustainable solution to facilitate long-term, self-sufficient human habitation in extraterrestrial environments. However, its dependence on Earth-supplied feedstocks renders in-space biomanufacturing economically nonviable. Here, we develop a process termed alternative feedstock-driven in-situ biomanufacturing (AF-ISM) to alleviate dependence on Earth-based resupply of feedstocks.
