Abstract: The aim of the present work is to measure radon concentration in wood. Solid state nuclear track detectors of type CR – 39 was used as measurement device. Eight different samples of imported and local wood were collected from markets. Samples were grinded, dried in order to measure radon concentrations in it. Cylindrical diffusion tube was used as detection technique. Results show that the higher concentration was in Iraqi sample 1 which recorded (14.02 ± 0.9) Bq / m3, while the less was in Emirates Sample which recorded (5.35 ± 1.2) Bq / m3. From the present work, all wood samples were with lowest concentrations of radon gas than other building materials.

Analysis the economic and financial phenomena and other requires to build the appropriate model, which represents the causal relations between factors. The operation building of the model depends on Imaging conditions and factors surrounding an in mathematical formula and the Researchers target to build that formula appropriately. Classical linear regression models are an important statistical tool, but used in a limited way, where is assumed that the relationship between the variables illustrations and response variables identifiable. To expand the representation of relationships between variables that represent the phenomenon under discussion we used Varying Coefficient Models

Groundwater is an essential source because of its high quality and continuous availability characterize this water resource. Therefore, the study of groundwater has required more attention. The present study aims to assess and manage groundwater quality's suitability for various purposes through the Geographical Information System GIS and the Water Quality Index WQI. The study area is located in the city of Baghdad in central Iraq, with an approximate area of ​​900 , data were collected from the relevant official departments representing the locations of 97 wells of groundwater in the study area for the year 2019, as it included physicochemical parameters such as  pH, EC, TDS, Na, K, Mg, Ca, Cl,  , and &nbs

  An experiment was conducted  to study the effect of four isolates of Pseudomonas   spp. on the growth of two plants  Radish & Cowpea  and on the concentrations of macro elements & microelements  . This experiment included two parts , the 1st. part included isolation and characterization of 4  isolates of Pseudomonas bacteria from local  Iraqi soils  Baghdad  . The 2nd part included planting two plants  Radish & Cowpea  in plastic pots size 5Kg -soil in the green house Biology Dept. College of Science , after planting  we added the isolates to the pots , and after 50 days, the growth parameters  length , fresh and dry  weight , percentage  of ger

 This article aims to identify the traditional industries and crafts that exist in the old city of Sana’a in Yemen. It also aims to explain the pioneering role that these industries play in attracting tourism,
