Measles is a highly infectious and contagious disease of the respiratory system caused by Morbilivirus (Hashiguchi et al., 2011). The clinical disease has been characterized by high fever , cough, conjunctivitis, coryza, malaise, maculopapular rash and erythematous patches throughout the body along with increased mortality among non-vaccinated children (Ellison, 1931; Fazlalipour et al., 2008)....

The presence of gas content in medium- and high-rank coal poses a threat to safety production. Safe extraction is based on correct understanding the pore structure coal. This work investigates characteristics evaluates their fractal structure. samples were collected from Huainan Coalfield Qinshui Coalfield, divided into four types, according difference surface bright characteristics. Through ad...

Stewart-Williams and Halsey provide an unusually broad synthesis of the enormous literature on gender gaps in hiring, letters recommendation, mathematical spatial abilities, email appointment-making, people vs things orientation, within-gender variability, salaries, occupational preferences, employment discrimination. They argue that sociocultural factors, while important, cannot by themselves ...

Gender disparities in participation many STEM fields, particularly computer science, engineering, and physics, remain prevalent Western societies. Stewart-Williams Halsey contend that an important contributor to these is gender differences career-related preferences are driven partly by biology. We argue understate the influence of cultural factors shaping preferences. provide evidence for over...
