In this paper, we take a creative look at the effect of cracking on the buckling of graphene sheets. We introduced a significant improvement in molecular mechanical calculations that more accurately examine the behavior of atomic bonds during the instability of nanostructures in the presence of defects. A molecular mechanics method based on the modified couple stress (MCS) theory to consider the size effect on the graphene plate is introduced. Primary cracks with different lengths, orientations, and numbers were examined. For each crack, buckling parameters such as critical load and buckling modes of graphene sheets were investigated. This model has better computational performance and less computational compactness than other models. Our studies show that cracks perpendicular to the load direction have a greater effect on buckling parameters, including modes and critical buckling load than cracks aligned to the critical load. Increasing the crack length will further reduce the critical buckling load. The effect of the number of cracks in two directions in buckling parameters was investigated. Increasing the number of cracks always decreases a critical buckling load. Increasing the number of cracks affects the first buckling mode more than others. The study of the eccentricity of cracks shows that with increasing the eccentricity distance, in cracks perpendicular to the loading direction, the critical buckling load will be further reduced. However, for cracks aligned with the load direction, increasing the eccentric distance has less effect on reducing the critical buckling load.

Tooth Size Discrepancy (TSD) forms part of the initial diagnosis and is considered when formulating a treatment plan for the individual patient. The present research aimed at determining the extent and prevalence in a representative orthodontic population in Libya, to determine the prevalence of tooth size discrepancies (TSDs) in orthodontic population among different malocclusion groups.

The classical Fisher exact test [1], which is unconditionally the uniformly most powerful unbiased (UMPU) test, requires randomization at the critical value(s) to be of size α. Obviously, one needs a non-randomized version of this. Rejecting the null only if the test-statistic’s outcome is more extreme than the critical values, reduces the actual size considerably. The modified Fisher exact test introduced in [2] additionally rejects the null when the test attains the critical value c(t) and the randomization probability γ(t) (that depend on the total number of successes T) exceeds a threshold γ0, which is determined such that, for all values of the nuisance parameter, the size of the unconditional modified test is smaller, but as close as possible to α. This greatly improves the size and power of the test as compared to, for example, the conservative nonrandomized Fisher exact test, while controlling the Type 1 error rate.

Temperature and size dependence magnetic moment of zigzag (n, 0) (n= 4, 6, 8, 10) copper oxide nanotubes (CuO NTs) have been computed by using a standard density functional theory. The computational work carried out by employing spin polarized generalized gradient approximation with revised Perdew Burke Ernzerhoff type parameterization along ab-initio approach. Bond length, binding energy and total magnetic moment have been analyzed and found that the bond length decreases at first and become saturated with increasing size of the nanotube.

Maintaining a healthy body weight is important for overall health and can help prevent and control many chronic conditions. However, the information surrounding the barriers to healthy eating (HE) and physical activity (PA) for weight maintenance among Saudi women of reproductive age is insufficient to design and develop intervention programs. To explore personal, social, and physical environmental factors that act as barriers to maintaining a healthy weight and how these barriers vary by socio-demographic and weight status. A cross-sectional study was conducted in 2014 using a stratified two-stage cluster sampling design comprising 408 Saudi women attending 12 Jeddah Primary Health Centers (JPHCCs). Data was collected using a structured questionnaire consisting of socio-demographic factors, eating habits (EHs), PA, and perceived barriers to a maintenance of healthy weight maintenance. Body mass index (BMI) and waist circumference (WC) data also were obtained.

High entropy alloys (HEAs) are alloys that contains multiple elements, often five or more principal elements in equiatomic or near equiatomic ratio with or without minor elements. As felt from the name, high mixing entropy is the sole parameter to decide the solid solution alloy formation in HEAs but, the mutual interaction between elements are key parameters to predict the phase formation in HEAs as proposed by some researchers. In this review the guideline for alloy design in HEAs for the formation of solid solution phases are proposed on basis of atomic size difference (δ), mixing entropy (ΔSmix), mixing enthalpy (ΔHmix), valence electron concentration (VEC) and electronegativity difference (Δχ).

Instant sorrel drink (IZD) was developed by processing purple sorrel calyx into powdery form by the method of infusion, and dehydration and size reduction. Another purple sorrel calyx was processed into liquid zobo drink (LZD); and both the IZD and LZD were subjected to sensory evaluation using the total number of thirty five (35) panels of judges and data was subjected to t-test and preference test analytical tools; and found that IZD was also acceptable by the sensory panelists because the T-tabulated is 2.064, while T-calculated is -14.37 with standard deviations of 0.32 (P≥0.05) between the means; hence, there was no significance difference between the reconstituted IZD and the LZD, because T-calculated is not greater than the T-tabulated.

Previous studies have shown that women who are overweight or obese are at risk for adverse reproductive outcomes, including infertility, gestational diabetes, and hypertensive disorders of pregnancy. However, information surrounding the risk factors for obesity among Saudi women of reproductive age is deficient due to the limited number of studies that assessed obesity prevalence among them.
