The lake sediments of Hässeldala Port in south-east Sweden provide an archive local and regional environmental conditions ~14.5-9.5 ka BP (thousand years before present) allow testing DNA sequencing techniques to reconstruct past vegetation changes. We combined shotgun with plant micro- macrofossil analyses investigate dating the Allerød (14.1-12.7 BP), Younger Dryas (12.7-11.7 BP) Preboreal (<11.7 BP). Number reads taxa were not associated sample age or organic content. This suggests that,...
New biostratigraphic (ammonoids and conodonts) geochemical data (carbonate carbon oxygen stable isotopes, organic isotopes) are presented for the Carnian (Upper Triassic) marine succession of Ma'antang, Jiangyou County, in Upper Yangtze Block (NW margin Sichuan Basin, China). In this locality, Ma'antang Formation lies on top Tianjingshan Formation, which is identified by occurrence peritidal cycles with stromatolite layers, includes a distinct karst surface its upper part. Below surface,...
Two significant stratigraphical microfossils, conodonts and radiolarians, are usually used for the Upper Triassic chronostratigraphy. The Baoshan Block was located in eastern Tethys during Late where biostratigraphical data of still poorly known. We collected new samples from Hongyan section (HY) study. This 24-m-thick Dabaozi Village, City, is mainly composed thin-layered limestones, sandstone siltstone. conodont fauna referred to Sevatian 1 (late Norian), which species Mockina englandi,...
Abstract The Sinemurian-Pliensbachian boundary event (ca. 193 Ma) is recorded as a global perturbation of the carbon cycle, evidenced by large negative carbon-isotope excursion in many marine sedimentary successions. Whereas multiple lines evidence testify that was associated with environmental and climatic changes, sea-level oscillations, biotic turnovers settings, record effects on continents are poorly known. In this paper, we report high-resolution δ13Corg palynological data from Lower...
Early Triassic microbialites are distributed widely in the shallow marine facies of Tethys Region, especially carbonate platform where they were deposited immediately after latest Permian mass extinction (LPME). Ten Griesbachian domed microbial mounds found an outcrop uppermost first member Feixianguan (FXG) Formation at Baimiaozi, which is located Beibei Upper Yangtze Region southwest China. Field investigations and thin-sections analyses indicated that oolitic limestone, bioclastic...
Due to the special tectonic background and complex geological evolution characteristics of South China Sea, reef dolomite reservoirs (sush as Well Xike 1) are widely developed. Based on drilling core data 1, structure geochemical reservoirs, including carbon, oxygen, hydrogen isotopes REE were systematically studied using petrological methods. It is found that show main diagenetic environment dolomites a low-temperature alkaline semi open oxidation environment; carbon oxygen generally lack...
Abstract Egg processing products lose their attraction due to protein oxidation and degradation, while the edible coating incorporating antioxidant antimicrobial agents can address this deficit. In work, chitosan (CS) in combination with ε-polylysine hydrochloride, tea polyphenols, nisin, vitamin C (CS-NH-TC) was applied as a novel material for preserving marinated eggs 20 days its effects on egg quality, structure were determined. The CS-NH-TC exhibited highest antibacterial activities...
Water quality safety early warning system is the key point of ensuring water resources and sustainable use. This paper describes by using RBF (Radical Basis Function) neural network model. The consists four parts: monitoring, evaluation, signal identify quality, decision management. study applied to determining analyzing hazard degree in Songhua River Basin. Results show that grade four, which at serious alert. practice result fuzzy evaluation method prove it feasible scientific combining...
Miocene is an important period for the development of global stromatolites. The petrological and geochemical characteristics stromatolite (dense porous) laminae record changes in paleo-environment, from a drilling hole, ZK-1 at Wudaoliang Hoh Xil Basin, Northern Tibetan Plateau. Based on core observations, these lacustrine stromatolites are hummocky, stratiform, or domelike shape. consist dense (microspar-rich) porous (microcrystalline). oxygen isotopes suggest that Formation formed...
Abstract Egg processing products lose their attractions due to protein oxidation, while the edible coating incorporating antioxidant and antimicrobial agents can address this deficit. In work, chitosan (CS) in combination with ε-polylysine hydrochloride, tea polyphenols, nisin, vitamin C (CS-NH-TC) was applied as a novel material for preserving marinated eggs 20 days its effects on oxidation structure, including total sulfhydryl, dityrosine, solubility hydrophobicity, intermolecular forces,...
In order to predict the capacity of lithium-ion batteries with small sample data. this paper, a grey neural network model composed and is presented, which used in an aeronautical equipment. Based on project example, Battery terminal voltage, Voltage measurement at charger Time vector for cycle are taken as main factors judge battery capacity. Take it input model. The results show that has high prediction accuracy, can effectively change reduce work intensity maintenance personnel.
Abstract This study aimed to develop and characterize the chitosan-edible coating solution (CS-NH-TC) incorporated with ε-polylysine hydrochloride, tea polyphenols, Nisin, ascorbic acid, then investigate their effect on physicochemical, antibacterial, sensory properties of marinated eggs stored at 4 °C for 24 days, without were set as control. The CS-NH-TC edible exhibited lowest particle size (582.6 ± 16.6 nm) polydispersity index (0.49) highest zeta potential (30.96) among coatings. FT-IR...
