Retinoic acid receptor-related orphan receptor (ROR) agonists have been shown to regulate circadian rhythms in cultured cells and improve various disease outcomes animal models. Because expression of the core nucleotide excision repair protein XPA is governed by clock, we examined whether a natural synthetic ROR agonist (nobiletin SR1078, respectively) impact cellular responses UV radiation hum...

ABSTRACT Quantifying the marine radiocarbon reservoir effect, offsets (ΔR), and ΔR variability over time is critical to improving dating estimates of samples while also providing a proxy water mass dynamics. In northeastern Pacific, where no high-resolution series has yet been established, we sampled ( 14 C) from exactly dated growth increments in multicentennial chronology long-lived bivalve, ...

Abstract The presence of toxic compounds in wastewater can cause problems for organic matter and nutrient removal. In this study, the long-term effect a model xenobiotic, 2-fluorophenol (2-FP), on ammonia-oxidizing bacteria (AOB), nitrite oxidizing (NOB) phosphate accumulating organisms (PAO) aerobic granular sludge was investigated. Phosphate (P) ammonium (N) removal efficiencies were high (&a...

To analyze the effects of nitrifying bacterial community structure on partial nitrification (PN) characteristics in a PN-immobilized carrier municipal wastewater under low-temperature shock, two carriers with different communities were investigated. The E1-immobilized contained high abundance ammonia-oxidizing bacteria (AOB; 38.59%), and E2-immobilized had low AOB 4.78%. results experiments dis...

As a new type of biological treatment process, membrane aerated biofilm reactors (MABRs), which have received extensive attention and research in recent years, could reduce energy consumption by 70% compared to the traditional activated sludge process. The MABR system uses bubble-free aeration material as carrier, counter-diffusion mechanism oxygen pollutants enables ammonium oxidizing bacteria...

Đề tài được thực hiện nhằm đánh giá khả năng chuyển hóa đạm của các chủng vi khuẩn nitrate chọn lọc từ ao nuôi tôm sử dụng cho hệ thống tuần hoàn trong thẻ trên bể. Thí nghiệm gồm 4 thức, mỗi thức lập lại 3 lần. Đối chứng: không bổ sung khuẩn; 2) Nghiệm 1: AOB TB7.2; 2: NOB TV4.2 và 3: hỗn hợp TB7.2 TV4.2. Kết quả thấy việc vào bể sinh học làm giảm hàm lượng khí độc ammonia nitrite nuôi, tăng t...

Controlling the spin dynamics and lifetimes is one of main challenges in spintronics. To this end, study diffusion two-dimensional electron gases (2DEGs) shows that when Rashba Dresselhaus spin-orbit couplings (SOC) are balanced, a persistent helix regime arises. There, striped pattern long lifetime, limited only by cubic SOC, its can be controlled in-plane drift fields. Here, we derive spin-di...
