It may increase the effect of diabetic, high blood pressure, and diuretic drugs. Don't use during pregnancy. A standard herb infusion or weak decoction is prepared as the traditional remedy. Depending on what it's employed for, cups are taken daily.

Microsoft ExcelTM any version from onwards Compatibility: CurTiPot is widely disseminated in universities, companies, etc. Analysis and Simulation freeware, version 4. This advanced resource takes ionic strength effects and activity coefficients in account.

Check dissociation constants now Configuration and Acid rain analysis 5 CurTiPot is released as freeware for personal, educational and non-commercial use; for other applications, contact the author copyright holder. There is no need to install or uninstall CurTiPot.

All preprogrammed equations and Visual Basic embedded macros are self-contained and completely removed when closing CurTiPot no functions added, no changes made to Excel. It is necessary to enable macros in Excel to activate the buttons that run the macros for iterative computing of pH, distribution curves generation, smoothing, etc.

If, while opening CurTiPot, Excel does not display an option 'enable macros' to click, update the configuration only once for a computer following simple instructions on the front page of CurTiPot, cell AM In addition, the CurTiPot option i version contains balloons bubble text with a numbered sequence of first steps to be followed by beginners, like a recipe.

Balloons can be deleted as they become superfluous. The Regression module of CurTiPot uses an Excel supplement named Solver for the determination of concentrations and pKas of acids and bases from titration data by nonlinear least squares regression. If not yet visible in the Excel Data tab, Solver needs to be activated by checking the box in the Excel Supplements list.

Solely instantaneous protonation-deprotonation equilibria and effects of ionic strength are computed. No other type of chemical reaction or phase transition is taken in account in the calculations, although they may occur for many combinations of acids and bases listed or not in the Database. The pH Calculator, Simulation and Regression modules estimate activity coefficients with help of the Davies equation.

There are more complete equations applicable at higher I e. Ion-ion iteration corrections are disregarded Titration and Distribution modules of CurTiPot; this does not affect the volume of titration end points stoichiometric points or equivalence points.

The author has not introduced any spyware, adware, viruses or malicious code in the program, as checked and assured by many of the distributors of the software see list. Bug reports and suggestions welcomed by e-mail gutz iq. Evaluate CurTiPot freeware Examples and Comments The all-in-one modular and interactive design of CurTiPot is user-friendly and lets you rapidly calculate the pH of any aqueous solution, from the simplest to the most complex one.

The Virtual Titrator makes the simulation of the titration curve of any acid, base or mixture a breeze; flexibility in the selection of sample size, concentration of ingredients, titration range, type, size and speed of titrant addition and dispersion of the "measurements" give great realism to the process.

Quick loading of dissociation constants and one-click data transfer from the Virtual Titrator to both of the data analysis modules - Evaluation and Regression - make it easy to compare a "graphical" or empirical method with the numerical one in a matter of seconds!

This is great for learning and teaching as well as for the optimization of new titrations. Introduce your experimental data pairs of volume of titrant and pH readings from de pH meter potentiometer with a combined glass electrode or another pH sensor directly into the spreadsheet of the Evaluation module.

Visualize the curve as you enter data point by point during the titration in the laboratory, or afterwards. Select the smoothing factor of the spline that shows the most accurate interpolation of the endpoints stoichiometric points or equivalence points on the derivative curves.

You will be pleasantly surprised with the effectiveness of spline smoothing for volumetric titration curves with clearly defined inflections and with the power of the Regression module to deal with more difficult data analysis.

Try the Regression module to obtain the best possible estimation of the concentrations and pKas of species involved in protonation chemical equilibria.

The chemometric approach of multiparametric least-squares nonlinear regression is effective when all relevant pKas fall within or near outside the pH range covered by your titration data.

A background in chemometrics, statistics or numerical data analysis is valuable but not essential to profitably explore the power and recognize the limits of the Regression module, in special, for data untreatable by graphical and linearization methods Gran plot.

For example, with Regressionminute concentrations of some acidic and basic components in acid rain samples titrated with strong base can be determined individually or grouped as follows:New eruption begins in early September , forcing evacuation of thousands.

Ambae (formerly called Aoba) is a large basaltic shield volcano in the New Hebrides arc that has generated periodic phreatic and pyroclastic explosions originating in the summit crater lakes Manaro Lakua and Voui during the last 25 years; the central edifice with the active summit craters is also commonly referred to.

Amphibian diversity is highest in the tropics, especially in the Amazon. Brazil has the most described species, over a 1, contrast, the United States. is nearly the same size as Brazil with about a third of the amphibian species (although it has many more salamanders!).

Leaching and recovery processes for zinc and copper from brass slag by sulfuric acid were carried out and iron and aluminum were also precipitated as hydroxides in addition to silica gel.

The Acid Rain Program is a market-based initiative taken by the United States Environmental Protection Agency in an effort to reduce overall atmospheric levels of sulfur dioxide and nitrogen oxides, which cause acid rain.

The program is an implementation of emissions trading that primarily targets coal-burning power plants, allowing them to buy and sell emission permits (called "allowances. Chanca piedra is a small, erect, annual herb that grows 30–40 cm in height. It is indigenous to the rainforests of the Amazon and other tropical areas throughout the world, including the Bahamas, southern India, and China.
