Wellbore stability is considered as one of the most challenges during drilling wells due to the 
reactivity of shale with drilling fluids. During drilling wells in North Rumaila, Tanuma shale is 
represented as one of the most abnormal formations. Sloughing, caving, and cementing problems 
as a result of the drilling fluid interaction with the formation are considered as the most important 
problem during drilling wells. In this study, an attempt to solve this problem was done, by 
improving the shale stability by adding additives to the drilling fluid. Water-based mud (WBM) 
and polymer mud were used with different additives. Three concentrations 0.5, 1, 5 and 10 wt. % 
for five types of additives (CaCl2, NaCl, Na2SiO3, KCl, and Flodrill PAM 1040) was used. 
Different periods of immersion (1, 24 and 72 hours) were applied. The results of the immersion 
test showed that using 10 wt. % of Na2SiO3 for WBM gives a high recovery percentage (77.99 %) 
after 72 hr, while the result of the dispersion test (roller oven) of 10 wt % of sodium silicate with 
WBM was (80.97 %) after 16 hr. Also, the immersion test result of 10 wt% of sodium silicate 
with polymer mud was (79.76 %) after 72 hr and the results of dispersion test (roller oven) of 10 
wt. % of sodium silicate with polymer mud was (84.51 %) after 16 hr.
Species of genus Chrotogonus (surface grasshoppers) are phytophagous and damaging to various economical important plants in their seedling stages. In order to know the biodiversity of surface grasshoppers, the detailed study has been conducted from four provinces of Pakistan. During this study, biodiversity, taxonomy, diagnosis, morphometric analysis, habitat, global distribution, and remarks of each species have been described. Total of 826 specimens were collected and sorted out into three species and three subspecies: C. (Chrotogonus) homalodemus homalodemus (Blanchard, 1836), C. (Chrotogonus) homalodemus (Blanchard, 1836), C. (Chrotogonus) trachypter

Smart cities have recently undergone a fundamental evolution that has greatly increased their potentials. In reality, recent advances in the Internet of Things (IoT) have created new opportunities by solving a number of critical issues that are allowing innovations for smart cities as well as the creation and computerization of cutting-edge services and applications for the many city partners. In order to further the development of smart cities toward compelling sharing and connection, this study will explore the information innovation in smart cities in light of the Internet of Things (IoT) and cloud computing (CC). IoT data is first collected in the context of smart cities. The data that is gathered is uniform. The Internet of Things,

ethyl) diazinyl)-2-aminophenol were synthesized by simple substitution of tryptamine with 2-aminophenol. 
Structures of all the newly synthesized compounds were characterized by FT IR, UV-Vis, Mass spectroscopy
and elemental analysis. In addition measurements of magnetic moments, molar conductance and atomic 
absorption. Then study their thermal stability by using TGA and DSC curves. The DCS curve was used to 
calculate the thermodynamic parameters ΔH, ΔS and Δ G. Analytical information showed that all complexes 
achieve a metal:ligand ratio of [1:1]. In all complex examinations, the Ligand performs as a tri
The researchers have recently noticed the interest in the problem of overweight and how to find solutions to it until it is now at the forefront in terms of innovating various and different methods and treatment methods, and the interest in developing health fitness is one of the most important requirements of physical activity for the trainees, which led to the multiplicity of sports activities that promote the health aspect For the individual, in addition to the aesthetic aspect, the problem lies in not adopting training programs according to codified scientific foundations aiming, in addition to reducing weight, to raise the general health level of the trainee participating in fitness institutes, as the trainers do not follow the

The shell model calculations are performed for each sd isotope chain, considering the sensitivity of changing the sd two-body effective interactions USDA, USDE, CWH and HBMUSD in the calculation of the one-body transition density matrix elements. The calculations incorporate the single-particle wave functions of the Skyrme interaction to generate a one-body potential in Hartree–Fock theory to calculate the single-particle matrix elements. For most sd shell nuclei, the experimental data are well rep
