Dysregulation of immune system, such as elevation levels of proinflammatory mediators and their roles in disease progression and pathogenesis as well as imbalance between innate and adaptive immune cells, are discussed in this review.

A Control Chart Based on Moving Average Model Functioned for Poisson Distribution

/in /by

A control chart used with MA control chart to track the number of faulty products or faults suggested. When the characteristics of quality of interest obey a Poisson distribution. A specified number of objects are observed at various time intervals in order to observe the number of non-conformities. By measuring ARLs under different sample sizes and parameters by considering ARLs in power, the output of the proposed chart is evaluated. It should be noted The proposed control chart seems to be more reliable than the traditional current control charts in detecting small adjustments in the manufacture process.

/in /by

The purpose of this paper is to study, in the first place, the theoretical relationship between Islamic financial development, investment and economic growth. Second, we empirically try to discover the interaction between “Islamic financial development, investment and economic growth”. Our empirical study highlights the direct effects of Islamic financial development on growth and investment. Finally, we also clarify the indirect effects of Islamic financial development on growth through Investment and vice versa, also on other socio-economic indicators over the period from 1990 to 2018, while using the model with simultaneous equations for the MENA region and East Asia and the Pacific.
