This study assessed the properties and toxicity (water cress germination trials) of 38 waste-derived, novel biochar-mineral composites (BMCs) produced via slow pyrolysis and hydrothermal carbonization (hydrochars). The biochars were produced from sewage sludge and compost-like output (CLO) by varying the type of mineral additive (zeolite, wood ash and lignite fly ash), the mineral-to-feedstock ratio and the carbonization process. While pure hydrochars completely inhibited germination of water cress, this effect was ameliorated by mineral additives...

To improve the methane yield and digestate utilization of anaerobic digestion (AD), low-cost composited accelerants consisting of urea (0.2-0.5%), bentonite (0.5-0.8%), active carbon (0.6-0.9%), and plant ash (0.01-0.3%) were designed and tested in batch experiments. Total biogas yield (485.7-681.9 mL/g VS) and methane content (63.0-66.6%) were remarkably enhanced in AD systems by adding accelerants compared to those of control group (361.9 mL/g VS, 59.4%). Composited accelerant addition led to the highest methane yield (454...

BACKGROUND & RATIONALE: High-mobility group box-1 (HMGB1) is a damage-associated molecular pattern (DAMP) increased in response to liver injury. Since HMGB1 is a ligand for the receptor for advanced glycation end-products (RAGE), we hypothesized that induction of HMGB1 could participate in the pathogenesis of liver fibrosis via RAGE cell-specific signaling mechanisms. RESULTS: liver HMGB1 protein expression correlated with fibrosis stage in patients with chronic Hepatitis C virus (HCV) infection, primary biliary cirrhosis (PBC) and alcoholic steatohepatitis (ASH)...

REVIEW
Craig F Morris
Noodles are a leading food in the world, and color is a key determinant of consumer acceptance. In this review the two prominent forms of wheat noodles are considered, white salted and alkaline. Many of the preparation and evaluation strategies are the same for both, with prominence placed on 'brightness' (L*) or a lack of discoloration (ΔL*), and the absence of 'specks'. All raw noodles darken over time. Increasing protein content of flours almost always translates into darker noodles. Greater discoloration is also associated with higher flour extraction rates, higher ash contents and higher starch damage...

Permian-Triassic (P-Tr) altered volcanic ashes (tuffs) are widely distributed within the P-Tr boundary successions in South China. Volcanic altered ashes from terrestrial section-Chahe (CH) and marine section-Shangsi (SS) are selected to further understand the influence of sedimentary environments and volcanic sources on diagenetic alterarion on volcanic tuffs. The zircon 206 Pb/238 U ages of the corresponding beds between two sections are almost synchronous. Sedimentary environment of the altered tuffs was characterized by a low pH and did not experience a hydrothermal process...

REVIEW
Yue She, Defa Li, Shuai Zhang
The role of phosphorus (P) in swine nutrition has been taken on new significance in recent years. Methods to determine the available phosphorus (AP) content of swine feeds include relative bioavailability (RBV), apparent total tract digestibility (ATTD), standardized total tract digestibility (STTD), and true total tract digestibility (TTTD). The RBV of P is determined by measuring bone ash or bone P, whereas the ATTD of P is determined by calculating the difference between P intake and P excretion in feces...

To understand the main properties of cement, a ubiquitous material, a sound description of its chemistry and mineralogy, including its reactivity in aggressive environments and its mechanical properties, is vital. In particular, the porosity distribution and associated sample carbonation, both of which affect cement's properties and durability, should be quantified accurately, and their kinetics and mechanisms of formation known both in detail and in situ . However, traditional methods of cement mineralogy analysis ( e...
