Heavy metal pollution in roadside soil fuel stations has been recognized for a long time of Nasiriyah city, south of Iraq.The study was conducted to examine the heavy metals content of three fuel stations in the nearby soil and control sample from rural area. The accumulation of heavy metals was tested, including the Lead (Pb), Nickel (Ni), Chrome (Cr)and Arsenic (As).Heavy metals were detected by using an atomic absorption spectrometer. The concentrations of Pb, Ni, Cr, and As in roadside soil was affected by fuel stations. Significant difference (p<0.05) in Pb, Ni, Cr, and As content were found in nearby soil samples of fuel stations compare with control sample. The results showed that urban samples had significantly (p<0.05) higher heavy metals compared to rural samples in all heavy metals studies. The results indicated that the rural areahad the lowest heavy metals content compared with nearby soil samples of fuel stations. It could be concluded that impaction of fuel station on the accumulation of heavy metals in roadside soils in urban area was slight.

Cystic hydatid disease is a significant global health concern and a hazardous obstacle for public health and the livestock industry. The present investigationisaimedto determinethe prevalence of hydatid cysts and economic losses in slaughtered animals (sheep,cattle, buffalo and camel) inThi-Qar province,south of Iraq.This research was carried out fromthe beginning ofFebruary 2022 to the end of January2023. The study focused on the prevalence of cystic echinococcosis in slaughtered animals from the central slaughterhouse of Nasiriyah city. The total cases (8847)were examined and the proportion of infection of hydatid cysts was: out of 2792 of examinedsheep, 343 (12.29%) were infected, out 3209 of examined cattle, 288 (8.97.%) were infected, out of 1865 of examined buffalo 154 (8.26 %) were infected and out 980 of examined camels, 40 (4.08%) were infected. Among the infected animals in the Al-Nasiriyahabattoir, sheep recorded the highest prevalence, while camel abattoir recorded the lowest prevalenceamong other animals intermediate hosts. The incidence of hydatid cysts has a positive proportion to the age of animals. Regarding organ involvements, the liver and lungs were the most infected organs, the liver had a higher prevalence than the lung with infection rates of 62.3 % and 37.70% respectively.Females of sheep, cattle, buffalo, and camel were statistically higher than males, and were significant differences between the
severityof infection and sex of hosts at (P≤0.05).Sheep was the highest fertility with 84.26%, this attributed to the sheep strains in this region have a higher morbidity rate compared to other regions.

About five million people lose their lives every year to lung cancer, making it one of the leading causes of mortality worldwide. In the last few years, a lot of methods of detection of lung cancer were improved however these could not efficiently diagnose cancer. In this paper, a convolutional neural network (CNN) of robust deep learning is developed. CNN precision raises the deeper that is, however, it causes over-fitting or vanishing gradient problems simultaneously. To solve the issue, the CNN used resort to parallel CNN.It used Pictures the LIDC-IDRI consortium image collection has thoracic CT images that have been annotated for lung cancer diagnosis and screening purposes. The presented model includes result models of CNN which are integrated via ensemble methods and it compare with every model. Results of the simulation illustrate that the presented method's accuracy has developed by 2.18 percent in comparisonwith the method of the main paper

This paper centers on an eco-epidemiological predator-prey model that accounts for hunting cooperation among predators and prey shelter and fear in afflicted prey. The objective is to investigate the effects of parameter factors on the model's bifurcation behavior. Theoretical part of this study demonstrate that a transcritical bifurcation can result from infection rate and refuge rate. Furthermore, fear rate can cause a Hopf-bifurcation to arise close to the positive equilibrium point. The presence of local bifurcations close to the non-trivial equilibrium points is verified by numerical analysis, which also guarantees the veracity of the theoretical results.

arious forms of boundedness in rectangular fuzzy n-normed linear spaces of type (????,????,∗)are examined in this work, where ∗represents an arbitrary t-norm. Some of these highly general notions of boundedness have no counterpart in the traditional topological metrizable linear spaces. We list the properties of these bounded sets and conduct a comparative analysis of the variousforms of boundedness. Among these are a number of ideas on the symmetrical characteristics of the objects under study that come from the classical context and are relevant to the issues of this magazine. We define their consequences and provide instances to show how different these notions are from one another.
