Biological invasion is one of the most threatening factors for biodiversity conservation. Lacking information on alien species in certain regions of the world hampers a balanced understanding of invasion processes and efficient data exchange among stakeholders. Current knowledge gaps are in need of urgent concern. We therefore conducted a review on alien animals in Xinjiang, an unknown region o...

The Solution.?The required dose should be dissolved in sterile distilled water in order to make a 5 per cent, solution, i.e., 0.05 gramme will require 1 c.c., 0.1 gramme 2 c.c., 0.2 gramme 4 c.c., and 0.3 gramme 6 c.c. The solution should not be boiled and should be prepared freshly. (We have used solutions that have been kept 48 and even 72 hours without any ill-effects but as there is danger ...

The Governor’s Proclamation of a Continued State of Emergency, issued on April 25, 2014, suspends the California Environmental Quality Act (CEQA) (Public Resources Code 21000 and following) for all actions taken by local agencies that are identified by the State Water Resources Control Board as vulnerable to acute drinking water shortages and that are necessary to implement solutions to such sh...

We study various solutions of the sine-Gordon model in (1+1) dimensions. We use the Hirota method to construct some of them and then show that the wobble, discussed in detail in a recent paper by Kälberman, is one of such solutions. We concentrate our attention on a kink and its bound states with one or two breathers. We study their stability and some aspects of their scattering properties on p...

the complexation reaction between hydroxyl ammonium (honh3+ ) cation with 18-crown-6 (18c6) ligand was studied in dimethylsulfoxide – water (dmso-h2o), methanol – water (meoh-h2o) and dimethylformamid – methanol (dmf-meoh), binary solutions at different temperatures using conductometric method. the obtained results show that the stoichiometry of the complex formed between honh3+ cation with (18...

In this work the effect of electrolytes on hydrate formation was investigated. To do so, a new model was used in predicting the hydrate formation conditions in presence of both single and mixed electrolyte solutions. The new model is based on the van der Waals - Platteeuw hydrate equation of state. In order to evaluate the values for the activity of water in electrolyte solutions t...

1. Previous work has suggested that living cells may acquire and then maintain different water contents and hence volume, in solutions containing different concentrations of solutes that are permeant to the cell membrane. Toward better understanding of this phenomenon, two hypotheses were introduced: one hypothesis is based on the membrane-pump theory; another represents an extension of the pol...

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

In this paper, we obtained the 1-soliton solutions of the symmetric regularized long wave (SRLW) equation and the (3+1)-dimensional shallow water wave equations. Solitary wave ansatz method is used to carry out the integration of the equations and obtain topological soliton solutions The physical parameters in the soliton solutions are obtained as functions of the dependent coefficients. Note t...

Edible and biodegradable films have been successfully explored at experimental level, attracting interest in the food preservation and packaging technology fields. However, film technology still presents several challenges for researchers. Namely, there is a lack of systematic information on the relationship between the composition and properties of film forming solutions and the properties of ...
