Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Study on the failure mechanism of the shield excavation face in the sandy cobble stratum under different buried depths

Deep Underground Science and Engineering, EarlyView.
Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

Deep Underground Science and Engineering, EarlyView.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

The natural history of periodontal disease—Part 2: In populations with access to dental care: The Studies of Health in Pomerania (SHIP)

Periodontology 2000, EarlyView., 2023
Abstract In this descriptive analysis of the 21‐year follow‐up data from the SHIP‐START cohort and the 7‐year follow‐up data from the SHIP‐TREND cohort, we report the progression of clinical attachment levels (CAL), age effects on CAL change, and a detailed description of CAL progression and remission. At baseline, 4307 and 4420 persons participated in

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

Developmental Dynamics, EarlyView.
Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic

THE RELATIONSHIP BETWEEN THE MECHANICAL PARAMETERS IN THE TAKE-OFF OF A VAULT AND THE DROP JUMP ABILITY

Science of Gymnastics Journal, 2015
In the vault in gymnastics, the take-off motion is important to the success of the vault and to perform more difficult vaults. Vaulting ability has been studied by motion analysis, but this method is not effective for easy evaluation.

Study on the Influence of Slope Static Load on Shallow Lining Support Structure

Energy Science &Engineering, EarlyView.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.
