In this paper, we presented new types of Mc-function by using 𝜔-open and 𝑁-open sets some of them are weaker than Mc-function and some are stronger, which are 𝜔Mc-function, M𝜔c-function, 𝜔M𝜔c-function, 𝑁Mc-function, M𝑁c-function and 𝑁M𝑁c-function, also we submitted new kinds of continuous functions and compact functions and we illustrated the relationships between these types. The purpose of this paper is to expand the study of Mcfunction and to get results that we need to find the relationship with the types that have been introduced.

This is the first time that the mechanical activity of Hedgehog i leal

smooth muscle is a regular spontaneous contraction to be reported. It was  found  that  the different concent1·ations of  papaverine exerted different dcgces of inhibition on ileal smooth muscle. The minimum

effective  dose  was  (0.05)  mM.  Different  concentration  of acetylcholine and KCI caused tonic contraction in this kind of smooth muscle. High concentration of papaverine caused inst<mt relaxation in acetylcholine or Kcl- excited muscle. The inhibitory effect of the drug resul ted from the reduction of the available  free calcium and caused relaxation.

This work describes a green synthesis route for zirconium oxide nanoparticles (ZrO₂ NPs) by using Zr sulfate and mint extract. This method is distinguished from other processes (physical and chemical) by its simplicity, cost-effectiveness, and low potential risks during preparation. Multiple techniques have been used to characterize and analyze ZrO₂ NPs, including Fourier transform infrared and ultraviolet visible spectra, crystal size calculation by X-ray diffraction, scanning electron and atomic force microscopes, energy-dispersive X-ray, and Zeta potential. Kinetic stability of the ZrO₂ NPs system, as indicated by the Zeta potential of -25.8 mV, suggests a long-term persistence and high surface charge.

A total of 179 thalassemia major patients were subjected to analysis in the hereditary blood diseases centre, including (18(10.05 %)) of intermarriages between different ethnic groups origin, whereas the overall consanguinity marriage rate was estimated at (161 (89.9%)) including (63(35.1%)) for first cousi

In this paper, the problem of scheduling jobs on one machine for a variety multicriteria
are considered to minimize total completion time and maximum late work. A set of n
independent jobs has to be scheduled on a single machine that is continuously available from
time zero onwards and that can handle no more than one job at a time. Job i,(i=1,…,n)
requires processing during a given positive uninterrupted time pi, and its due date d
i.
For the bicriteria problems, some algorithms are proposed to find efficient (Pareto)
solutions for simultaneous case. Also for the multicriteria problem we proposed general
algorithms which gives efficient solutions within the efficient range

In this work we run simulation of gas dynamic problems to study the effects of Riemann
problems on the physical properties for this gas.
We studied a normal shock wave travels at a high speed through a medium (shock tube). This
would cause discontinuous change in the characteristics of the medium, such as rapid rise in
velocity, pressure, and density of the flow.
When a shock wave passes through the medium, the total energy is preserved but the energy
which can be extracted as work decreases and entropy increases.
The shock tube is initially divided into a driver and a driven section by a diaphragm. The
shock wave is created by increasing the pressure in the driver section until the diaphragm bursts,
