The excitation, growing and damping of current instability is an important and vital subject for a lot of studies through its importance in communication for instance and in understanding the nature of space and the interpretation of many phenomena in space and astrophysics. Recent analytical and numerical works are presented to describe and investigate the excitation and growing of kinetic electron-ion two streams instability in anisotropic inhomogeneous dusty space plasmas. We elucidated the thermal effects of plasma species on the characteristics of such instability. It is found that the gradient of space plasma temperature, , is a cause of interesting physical phenomena. Besides, different parameters, such as electron to ion temperature ratio , magnetized plasma and dust grains, are also found to play a crucial role in the growth and depression of such instability.

Background: dietary habit is one of the most universally recounted initiators of irritable bowel syndrome (IBS). The objective of the present study was to determine the role of some dietary habits in the etiology of IBS in Northern Saudi Arabia. Methodology: In this community based cross-sectional survey, data about IBS were obtained from 930 Saudi volunteers living in the city of Hail, Northern Saudi Arabia. IBS was diagnosed using Rome IV criteria. Results: The prevalence of IBS was 11% among males vs. 12.5% among females. The prevalence of IBS symptoms among males was 30% vs. 36.5% females. IBS was significantly associated with reduced water intake, the RR (95% CI) = 1.1800 (1.0146 to 1.3722), P = 0.0316. In the present study, the majority of the study population 904/929 (97.3%) didn’t accustom to vegetables/fruits intake. Conclusion: IBS is prevalent in Northern Saudi Arabia, both among males and females with relatively increasing among females. Low water intake and insufficient fibers intake (particularly, in vegetables and fruits) might be behind the growing prevalence of IBS in Saudi Arabia.
