Umid Mirzakulov, Muzaffar Makhkamov, Islomjon Khudoyberdiyev
American Journal of Polymer Science, 2023, 12(2), pp. 32-36
DOI: 10.5923/j.ajps.20231202.02

Open Access
In this work, the sorption of malachite green (MG) from aqueous solutions by polymer composite gels (PCG) prepared on the basis of polyacrylic acid and bentonite clay (BG) was studied. It was found that the sorption capacity of PCG containing 50 weight % BG is almost three times greater than that of ...

Urban Spatial Structure and the Density of Retail Shops in Cities
Peter Maluki Samburu, Fredrick Omondi Owino, Naomi Apali Mogoria
Architecture Research, 2023, 13(2), pp. 59-83
DOI: 10.5923/j.arch.20231302.03

Open Access
The variability of the location and retail shop density relative to the urban structure of informal and formal settlements are pervasive issues in many cities. Therefore, this study examines the relationship between street metric properties and retail shop density and the association between spatial ...

Discovery of a Universal Static Thermal Repulsive Force
Liu Ke Dian
International Journal of Theoretical and Mathematical Physics, 2023, 13(3), pp. 59-74
DOI: 10.5923/j.ijtmp.20231303.01

Open Access
This paper aims to present the key points of the discovery of a universal static thermal repulsive force. The breaking through point is to clarify and verify the gas pressure being not caused by the collisions of gas molecule but by a universal static thermal repulsive conservative contact force. If ...

Sarhan Hasan, Salah Eddin Altaher Albakoush, Mawloud Jummah Mawloud Albakoush, Abdelhamid Egzil, Salah Eltief
Electrical and Electronic Engineering, 2023, 13(2), pp. 19-23
DOI: 10.5923/j.eee.20231302.01

Open Access
Voltage control and system stability rely heavily on reactive power. In electric power systems, various Volt/VAR techniques are used to keep the voltage profile within a defined acceptable range, providing reliability, stability, and economic benefits. Reactive power has traditionally been generated ...

Derivation of a Most Reasonable Novel Atom Model
Liu Kedian
Physical Chemistry, 2023, 12(1), pp. 1-12
DOI: 10.5923/j.pc.20231201.01

Open Access
This paper aims to present the derivation of a most reasonable novel atom model. In the novel atom model, the nucleus-electrons system is in a static equilibrium state between a universal static thermal repulsive conservative force and Coulomb force.
