Organismal homeostasis requires regulation of extracellular acid-base status; however, the mechanisms by which insects regulate haemolymph pH are poorly known. We evaluated the recovery of desert locusts Schistocerca gregaria Forskal from acute acid loads, initiated by HC1 injections into the haemolymph (0.5 pH unit decrease). Haemolymph pH, PCO2 and [HCO3~] recovered in 8-24h, providing the fi...

Delay jitter is a critical factor that must be considered in many real-time applications that require accurate prediction of packet delivery times. Delay jitter can be smoothed by holding packets in a play-back buffer for a certain time called a play-back delay. In this paper, we extensively examine the new scheme that we have proposed in [1] to enhance the prediction of the play-back delay in ...

Abstract It is increasingly evident that climate sustainability depends not only on societal actions and responses, but also ecosystem functioning responses. The capacity of global ecosystems to provide services such as sequestering carbon regulating hydrology being strongly reduced both by change itself unprecedented rates degradation. These rely functional aspects are causally linked—the same...

Riparian buffer strips are a widely accepted tool for helping to sustain aquatic ecosystems and to protect downstream resources and values in forested areas, but controversy persists over how wide a buffer strip is necessary. The physical integrity of stream channels is expected to be sustained if the characteristics and rates of tree fall along buffered reaches are similar to those in undistur...

On path tracking control of vehicles via the Internet, transmission delay and jitter prevent them from a target accurately. To improve accuracy, it is effective to apply digital twin computing buffer system. The system with has an issue optimizing buffering time. Through simulations by using some realistic models, we quantitatively evaluated accuracy depending on As result, showed that buffered...

The objective was to quantify how the concentration and particle size of unreacted “residual” limestone affected pH buffering capacity for ten commercial and nine research container substrates that varied in residual calcium carbonate equivalents (CCE) from 0.3 to 4.9 g CCE·L. The nine research substrates contained 70% peat:30% perlite (by volume) with dolomitic hydrated lime at 2.1 g·L, follow...

Abstract Here, we report the results of experiments regarding chemical repositioning 4‐(2‐hydroxyethyl)‐1‐piperazine ethane sulfonic acid ( HEPES ), a representative buffering agent. In this work, confirmed that could disaggregate amyloid plaques, hallmark Alzheimer's disease, and verified its sustained‐release system (release for up to 2 weeks) via hybridization with biocompatible polymer (Eud...

This report describes the challenges in meeting the requirements for optical buffering devices in next -generation optical routers. Slow light and delay line buffering approaches are described and several recent results and issues are summarized.
