In this paper, a harvested prey-predator model involving infectious disease in prey is
considered. The existence, uniqueness and boundedness of the solution are
discussed. The stability analysis of all possible equilibrium points are carried out.
The persistence conditions of the system are established. The behavior of the system
is simulated and bifurcation diagrams are obtained for different parameters. The
results show that the existence of disease and harvesting can give rise to multiple
attractors, including chaos, with variations in critical parameters.
The transformation of a physical system to mathematical base is very important due to analysis of the systems behavior. In this paper an electric power system is considered, we design mathematical model for the determination of the increase in operational cost of transmission line from Haditha Dam substation to Qa'im substation . We derived relations which the approximate distance for VARS transmission must satisfy with considering minimum losses in the system. MATLAB computer programming is used to obtain the numerical results. The developed mathematical model and the numerical results could be useful to electric power systems engineers

An adaptive technique has been proposed to improve the performance of this method.Watershed transform algorithm based on clustering techniques: K-Means and FCM were implemented to reduce the oversegmentation problem. The K-Means and FCM clustered images were utilized as input images to the watershed algorithm as well as of the original image. The relative surface area of the extracted tumor region was calculated for each application. The results showed that watershed trnsform algorithm succeedeed to detect and extract the brain tumor regions very well according to the consult of a specialist doctor a

No inhibitory effect was noticed against Escherichia coli or Enterococcus faecalis. However, variable effects were developed against Methicillin resistant Staphylococcus aureus (MRSA), methicillin sensitive Staphylococcus aureus (MSSA), Klebsiella pneuminae and Staphylococcus epidermidis. The flaxseed exhibited antibiofilm activity against all tested bacterial isolates (MSSA, MRSA, S. epidermidis and K. pneumoniae) and showed various degrees of inhibition against them. Experimental wounds were healed by application of flaxseed oil. In conclusion, flaxseed oil is a good alternative medication can be u

The main problem is to divide these networks into partitions called communities, which are characterized by dense connections inside each part but sparse connections between them. Most networks in the real world display a community structure that must be detected and recovered. There are many approaches (techniques) for detecting communities, which may be arranged in classes according to various bases, like the operational method or the adopted definition of community. However, just a few desired algorithms are applied and adopted for identifying communities, like optimization of quality functions. This review highlights the existing modu

The genus is nearly worldwide distributed, but disjunct, sporadic, and localized throughout the range in North America, South America, Europe, Africa, and Australia. According to the published checklist, only two species of Sphaerocarpos were recorded in the middle east countries. These are S. texanus and S. michelii, both were found in Turkey, while only the latter was found in Iraq.

... Show MoreJudith Wright's (1915-2000) concern about man's disintegration with the natural world and the horror of the destruction of the earth reflects a high sense of ecological awareness caused by the threat of pollution that pervades the environment. Wright's ecopoetry draws attention to the danger of displacing oneself from the natural world that would also cause an inner alienation in man. The purpose of this paper is to explore Wright’s ecopoetical representation of the Australian ecology and its integral connection with Australia’s national unity. As the study examines Wright’s various volumes of poems, it argues that the lack of ecological awareness weakens the national and social fabric of Australia and deteriorates its environment.

A computer program has been created to calculate the Roche Limit of the rings and satellites of Saturn, showing that many of the rings of the planet are located outside the Roche Limit and still intact and do not accumulate and clump since ancient times, and that many of Saturn satellites are located within the Roche Limit and have not been influenced and crumbled by the tidal forces of the planet. The change of the rings width was studied as a relative function of the mass with the distance from the planet, and the satellite diameters change as a relative function of the mass with the distance from the planet. The results were compared with the condition of the planets and the sun showing almost similar change in the two cases, which in
