With the threat of significant morbidity and mortality following an influenza pandemic, stockpiling of antiviral agents such as oseltamivir is recommended. Shelf-life extension was explored to maximize use of an existing stockpile. This analysis demonstrated that oseltamivir retains potency defined by United States Pharmacopeia acceptance criteria beyond the labeled expiration date.

Phosphogypsum is an acidic solid waste mainly composed of CaSO₄-2H₂O by-products of the wet process phosphoric acid industry, which has the characteristics of high impurity content, poor stability of stockpiling, but can be utilized in a resourceful way. Phosphogypsum waste utilization can reduce environmental pollution, save resources and create economic value. In order to investigate the fatigue characteristics and the mechanism of dynamic strength change of cement-phosphogypsum-red clay under wet and dry cycles, the cumulative deformation characteristics and the rule of change of critical dynamic stress of the mixed materials were investigated by dynamic triaxial fatigue test, SEM and XRD test, and the mechanism of dynamic strength change was analyzed according to the microstructure and the chemical mineral composition of the mixed materials.

Accurate estimation of the quantity of localized construction and demolition waste (CDW) is critical for optimizing the upstream operations of the CDW's reverse supply chain (RSC). However, existing studies extensively focus on downstream RSC operations with approaches that quantify large-scale material stockpiles through semi-automated workflows relying on expensive, non-portable devices. These approaches are impractical for upstream operations such as quantifying small-scale, localized CDW stockpiles scattered around urban environments, requiring frequent estimations.

The cold recycling (CR) technique is gaining traction, with an increasing demand for sustainable pavement construction practices. Cold in-place recycling (CIR) and cold central plant recycling (CCPR) are two strategies under the umbrella of cold recycling. These techniques use reclaimed asphalt pavement (RAP) to rehabilitate pavement, and CCPR offers the added advantage of utilizing stockpiled RAP.

The worldwide accumulation of scrap tires presents a significant waste management challenge with major environmental and health implications, where, the stockpiles of waste serve as breeding grounds for disease-carrying insects. Meanwhile, the rapid rise in energy demand brings mounting pressure to develop renewable and sustainable fuel options. One strategy is to produce hydrogen based fuel via waste thermochemcial recycling but transporting and storing hydrogen remains difficult due to its physical properties.

Thraustochytrids are marine protists of ecological and biotechnological importance. Like many other eukaryotes, their life cycle includes a critical transition from a flagellated, swimming zoospore dispersal stage to a settled, surface-attached, growing vegetative cell. Unlike other eukaryotes, the settling vegetative cells of thraustochytrids (and their labyrinthulomycete relatives) attach to surfaces by producing a unique structure known as the ectoplasmic network, and its associated connection to the cytoplasm, the bothrosome.
