The addition of biochar,sodium silicate,or earthworm is a feasible practice to repair soils disturbed by mining activities,and the reclamation is largely based on the alteration of the diversity and structure of soil *** objectives of this study were to assess the relative importance of these supplements on soil bacterial community diversity and structure in reclaimed mine areas.A field experiment with soybean was carried out in mining areas to assess the efficiency of nitrogen,phospho-rus and potassium(NPK)fertilizers plus those supplements on soil bacterial community structure and diversity by the 16S rRNA sequencing *** chemical properties were analyzed to their effects on the bacterial community *** results showed that the application of nitrogen,phosphorus and potassium(NPK)fertilizers significantly increased bacterial diversity,and a further increase was observed in NPK plus biochar,sodium silicate or earthworm ***,a higher number of genera were found in the NPK plus biochar and NPK plus earthworm treatments than that in the control,NPK and NPK plus sodium silicate *** bacterial community was significantly associated with nutrients,such as carbon(C)and nitrogen(N).Moreover,soil organic carbon(SOC)and pH were the most dominant factors in shaping the soil bacterial community structure and *** data indicate that the addition of earthworms to soil rather than biochar and sodium silicate was the best strategy to mitigate the detrimental effects of mining activities on soil bacterial diversity.

The viscosity at the glass transition of a liquid lubricant

引用

Friction 2019年第1期7卷 86-91页

作者： scott BAIR Center for High-Pressure Rheology George W.Woodruff School of Mechanical Engineering Georgia Institute of Technology

In the classical study of elastohydrodynamic lubrication(EHL) which does not employ real, measurable viscosity in analysis, the possibility of a glass transition has not been considered in many years. Indeed, the two rheological assumptions of classical EHL, the Newtonian inlet and the equivalence of a traction curve to a flow curve, would not have persisted so long had the pressure dependence of the viscosity been accurately stated. With the recent appearance of viscosity obtained from viscometers in EHL analysis, the possibility of a glass transition in the contact should be reexamined, especially for the fragile traction fluids. This article employs published data for a synthetic cycloaliphatic hydrocarbon to estimate the glass transition viscosity so that, when using real viscosities in EHL simulations, the state of the liquid may be assessed. Far into the glassy state the liquid should be treated as an elastic solid with a yield stress.

Investigation on Liquid Holdup in Vertical Zero Net-Liquid Flow

Chinese Journal of Chemical Engineering 2001年第3期9卷 284-290页

Zero net-liquid flow (ZNLF) is a special case of upward gas-liquid two-phase flow. It is a phenomenon observed as a gas-liquid mixture flows in a conduit but the net liquid flow rate is zero. Investigation on the liquid holdup of ZNLF is conducted in a vertical ten-meter tube with diameter of 76 mm, both for Newtonian and nonNewtonian fluids. The gas phase is air. The Newtonian fluid is water and the non-Newtonian fluids are water-based guar gel solutions. The correlations developed for predicting liquid holdup on the basis of Lockhart-Martinelli parameter are not suitable to ZNLF. A constitutive correlation for the liquid holdup of vertical ZNLF was put forward by using the mass balance. It is found that the liquid holdup in ZNLF is dependent on both the gas flow rate and the flow distribution coefficient.

Drug induced acute pancreatitis: Does it exist?

引用

World Journal of Gastroenterology 2014年第44期20卷 16529-16534页

作者： scott Tenner Division of Gastroenterology Department of Medicine State University of New York Downstate Medical Center State University of New York

As the incidence of acute pancreatitis continues to rise, establishing the etiology in order to prevent recurrence is important. Although the etiology of acute pancreatitis is not difficult in the majority of patients, almost a quarter of patients are initially labeled as having idiopathic acute pancreatitis. When confronted with a patient with acute pancreatitis and no clear etiology defined as an absence alcoholism, gallstones(ultrasound and/or MRI), a normal triglyceride level, and absence of tumor, it often appears reasonable to consider a drug as the cause of acute pancreatitis. Over 100 drugs have been implicated by case reports as causing acute pancreatitis. While some of these case reports are well written, many case reports represent poorly written experiences of the clinician simply implicating a drug without a careful evaluation. Over-reliance on case reports while ignoring randomized clinical trials and large pharmacoepidemiologic surveys has led to confusion about drug induced acute pancreatitis. This review will explain that drug induced acute pancreatitis does occur, but it is rare, and over diagnosis leads to misconceptions about the disease resulting in inappropriate patient care, increased litigation and a failure to address the true entity: idiopathic acute pancreatitis.

Daily shoaling patterns in the zebrafish Danio rerio

引用

Current Zoology 2013年第6期59卷 754-760页

作者： Timothy PACIOREK scott McROBERT Department of Biology Saint Joseph's University Philadelphia PA 19131 USA

Shoaling intensity in zebrafish Danio rerio is believed to vary throughout subjective day and night hours. This experiment examines long term variations in shoaling behavior. Adult zebrafish Dan io rerio were maintained under a 12：12 LD cycle （with dim red light serving as reduced visibility during subjective dark hours）, and their shoaling behavior was monitored every hour for a three-day period of time. Our results show that zebrafish perform shoaling behavior throughout subjective day and under reduced visibility conditions, although mean shoaling times during the light phase were significantly higher than mean shoaling times during the dark phase. However, on the 3^rd day of the experiment, mean shoaling times during the subjective night had increased and mean shoaling times during the subjective day had decreased. This shift in intensity was not seen on the first two days of the study, and may represent the influence of experience on the behavior of the test fish. We believe this study shows that shoaling behavior changes with light/dark cycles and that fish shoal even during reduced visibility conditions.
