Female Genital Mutilation (FGM) which involves alteration of the female genitalia for non-medical grounds is prevalent in Sub-Saharan Africa, associated with long-term genitourinary complications, and possible HIV transmission. This mini-review aims to examine FGM and the possibility of HIV transmission through this procedure. We performed an electronic search using Medline for articles publish...

Floating-Gate Memory In article number 2105472, Young-Jun Yu and co-workers systematically design demonstrate multiple bits on non-volatile memory based vdW heterostructure floating-gate (FGM) by tuning the dimensions of 2D materials. A fingerprint mechanism is established that links bit crystals heterostructures. This approach could enable precise generation desired in layered-material-based F...

Cylindrical shell in engineering has different cross-section, i.e., circular section, oval rectangular and so on. In this work, numerical analysis is conducted on natural vibration of cylindrical with the difference studied between modal frequency shape from section shell. Numerical results show that, same length, width /thickness boundary condition, first 10 order nearly 60% bigger than that T...

understanding how a cutout influences the load bearing capacity and buckling behavior of cylindrical shells is fundamental in the design of structural components used in automobiles, aircrafts, and marine structures. in this article, simulation and analysis of steel cylindrical shells with various lengths, include quasi elliptical cutout, subjected to axial compression were systematically carri...

BACKGROUND Female genital mutilation (FGM) is a common traditional practice in developing nations including Ethiopia. It poses complex and serious long-term health risks for women and girls and can lead to death. In Ethiopia, the geographic distribution and factors associated with FGM practices are poorly understood. Therefore, we assessed the spatial distribution and factors associated with FG...

In this paper an optimization problem for a cylindrical shell is discussed. The aim is to look for an optimal thickness of a shell to minimize the deformation under an applied external force. As a side condition, the volume of the shell has to stay constant during the optimization process. The deflection is calculated using an approach from shell theory. The resulting control-to-state operator ...

~This report presents the first stage of an investigation of the response to random noise of a stiffened cylinder, representing an aircraft fuselage, including an analysis of the lower modes of such a cylinder. Preliminary investigations suggested that assumptions and approximations which are valid for the uniform, i.e., unstiffened, shell are not necessarily valid for a shell with heavy stiffe...

Bolted flange joints are commonly utilized in engineering constructions; nevertheless, their dynamic behavior is complicated when nonlinearity present. The bolted joint structure this research considered as a spring-mass system, and the equivalent axial two bi-linear springs-bending beam model, well system’s vibration control equation, created to examine structure’s characteristics under transv...

In some cases the optimum is the minimum of the objective function (mathematical optimum), but in other cases the optimum is given by a technical constraint (technical optimum). The present paper shows the both types in two problems. The first problem is to find the optimum dimensions of a ring-stiffened circular cylindrical shell subject to external pressure, which minimize the structural cost...
