Decoding the response of complete autotrophic nitrogen removal over nitrite (CANON) performance and microbial succession to hydrazine and hydroxylamine: Linking performance to mechanism.

The influence of hydrazine (NH) and hydroxylamine (NHOH) on performance and microbial community structures of complete autotrophic nitrogen removal over nitrite (CANON) process were assessed in this study. Experimental results demonstrated that CANON process was successfully started up and got total nitrogen removal efficiency (TNRE) of 53.6 % ± 9.

Effect of CaCl on 2 heat-induced whey protein concentrate fibrillation pathways: Spontaneous and nuclear induction.

Amyloid fibrils have many excellent functional properties that facilitate their applications in the food industry. There are 2 pathways for whey protein concentrate (WPC) to form amyloid fibril aggregates: spontaneous pathway and nuclear induction pathway. Low ionic strength is a necessary condition for the spontaneous pathway to proceed successfully.

Unenhanced low-dose versus standard-dose CT localization in patients with upper urinary calculi for minimally invasive percutaneous nephrolithotomy (MPCNL).

Background & Objectives: With the ethical concern about the dose of CT scan and wide use of CT in protocol of suspected renal colic, more attention has been paid to low dose CT. The aim of the present study was to make a comparison of unenhanced low-dose spiral CT localization with unenhanced standard-dose spiral CT in patients with upper urinary tract calculi for minimally invasive percutaneous nephrolithotomy (MPCNL) treatment.

Methods: Twenty eight patients with ureter and renal calculus, preparing to take MPCNL, underwent both abdominal low-dose CT (25 mAs) and standard-dose CT (100 mAs).

A SMAD3 gene polymorphism is related with osteoarthritis in a Northeast Chinese population.

Variants in the SMAD family member 3 (SMAD3) have recently been reported to be associated with osteoarthritis (OA) in European populations. However, the results are contestable. To assess the role of such variants in SMAD3 in OA susceptibility in peripheral joints OA, we conducted a case-control study in a Northeast Chinese population.

Morphology and properties of hybrid composites based on polypropylene/polylactic acid blend and bamboo fiber.

The design of new composites based on a polypropylene (PP)/polylactic acid (PLA) matrix and filler bamboo fiber (BF) leads to changes in process ability, morphology, and rheological properties of the raw thermoplastic. We have designed more environmentally friendly composites blended with PLA, filled with bamboo fiber. To refine dispersion of PLA and improve composite toughness, MAH-g-PP was included in the filler-matrix interface to enhance interface strength for PP, PLA and BF.
