a sensitive and selective kinetic-spectrophotometric method was developed for the determination of trace amounts of uric acid. the method is based on the inhibitory effect of uric acid on the oxidation of janus green by bromate in the presence of sulfuric acid. the reaction was followed spectrophotometrically by measuring the absorbance at 518 nm using the fixed-time method. under optimum exper...
In this study, using Sediment rating curve models USBR, seasonal model, monthly model, data model based on separating dry and wet seasons, data separation based on flow measurement time (months of low water and high water seasons) and separation of data based on months with no green vegetation and green vegetation] on 6 hydrometric station in Gharesoo River in Golestan Province with aim of se...
Background & Objective: Interferon belongs to a family of cytokines, which has the most important role in the innate immune response to virus infections. While producing recombinant interferon in biological host, some pieces of host nucleic acids remain in product. Because of limitations in previous techniques for detection of these impurities, the objective of this study is to use rapid ...
We prove the Prym–Green conjecture on minimal free resolutions of paracanonical curves of odd genus. The proof proceeds via curves lying on ruled surfaces over an elliptic curve.
Accurately modeling the land surface phenology based on satellite data is very important to the study of vegetation ecological dynamics and the related ecosystem process. In this study, we developed a Sigmoid curve (S-curve) function by integrating an asymmetric Gaussian function and a logistic function to fit the leaf area index (LAI) curve. We applied the resulting asymptotic lines and the cu...
(2) More seriously, the friction force depends on how you control the temperature in the simulation. Temperature is typically controlled in these simulations using a thermostat attached to the bottom of the system. As the green curve shows, by varying the thermostat parameter, one can basically get the friction to become arbitrarily small, even though the temperature of the heat bath is the sam...
background identification of a normal range for biomarkers, based on pregnancy outcomes (caused by their high or low values) is of special importance in clinical studies. as some pregnancy outcomes can happen in both high and low levels of biomarkers, the receiver-operating characteristic (roc) curve is unsuitable for identifying these levels separately; rather, a statistical method is preferab...
In Iran, there is a general risk of runoff and flood, and since this country has a dry to semi-arid climate, its predominant rainfall is not evenly distributed in terms of time and place. Routine runoff at the earth's surface can lead to risks such as groundwater abatement, social issues such as population migration, erosion and loss of soil fertility, sedimentation in reservoirs and water q...
In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...
A biofuel cell is a device for converting chemical energy to electrical energy by a simple way. A high-impact anode is prepared in this research. Here, carboxylated multiwall carbon nanotube (COOH-MWCNT), polydiallyldimethyl ammonium chloride (PDDA) and alcohol dehydrogenase were cast on modified glassy carbon with polymethylene green to construct the bioanode for ...
