This paper presents a new method for separating Rhenium, Molybdenum, Vanadium and Tungsten ions on a thin layer of Perlite using the thin layer -electro-chromatography method. This method is based on the combination between chromatographic forces and electric forces by applying different voltages on the separation plate for different times using several electrolytes as different mobile phase concentrations, at different applying field duarations on the process. This method also shows the possibility of using Perlite as a thin layer in this kind of separation process, which can apply in the separation of other types of biochemistry and inorganic ions This relatively simple method is cost effective.

Cancer stem cells (CSCs) are cancer cells that possess characteristics associated with normal stem cells, specifically the ability to give rise to all cell types found in a particular cancer sample. CSCs are therefore tumorigenic. The existence of CSCs is under debate and the origin of CSCs is an active research area. CSCs may generate tumors through the stem cell processes of self-renewal and differentiation into multiple cell types. Cancer stem cells (CSCs) have been identified in head and neck squamous cell carcinoma (HNSCC). So, development of specific therapies targeted at CSCs holds hope for improvement of survival and quality of life of cancer patients, especially for patients with metastatic disease like (HNSCC).

Melanoma is a leading fatal illness responsible for 80% of deaths from skin cancer. It originates in the pigment-producing melanocytes in the basal layer of the epidermis. Melanocytes produce the melanin (the dark pigment), which is responsible for the color of skin. As all cancers, melanoma is caused by damage to the DNA of the cells, which causes the cell to grow out of control, leading to a tumor, which is much more dangerous if it cannot be found or detected early. Only biopsy can determine exact malformation diagnosis, although it can rise metastasizing. When a melanoma is suspected, the usual standard procedure is to perform a biopsy and to subsequently analyze the suspicious tissue under the microscope.

Tax revenue is one of the most important ways for countries to supplement their public budgets with revenues needed for public spending. Given its characteristics and qualities, tax revenue is a very important tool of widespread fiscal policies used by countries to reduce the problems experienced by their economies, such as inflation, stagnation and unemployment. Tax changes are supposed to be in line with GDP changes, in the rise and fall. In this research I will examine the change in tax revenues in Syria compared to the change in GDP at current prices in the period from 2000 to 2016. The conclusion the study reaches is that the changes in taxes are incompatible with the changes in the GDP. This shows the inflexibility of the taxation system in Syria, which in turn has led to low tax revenues and a decrease in tax burden.
