This study aims to monitor and analyze the recent trends of the researches about the impact of the artificial intelligence on the journalism and television at the level of Arab and foreign studies from different research schools on all over the world in the period from 2017 to 2021.Also, it aims to know the subject fields about the artificial intelligence studies and to know the use of its techniques in journalism and television. This study is of the descriptive and analytical studies, and it depends on using the analysis style of the second level,According to this, the study depends on the qualitative analysis for the scientific studies related to the field of the artificial intelligence studies and its impact on the journalism and television,The results of this study are the following: - There is a variety for the recent trends of the researches about the impact of the artificial intelligence on the journalism and television in the period from 2017 to 2021. - The researches about the impact of artificial intelligence on the journalism are at the top of the interests list with average (84.2%), whereas the researches about the impact of artificial intelligence on television are with average (15.8%),The importance of using the technology of unmanned aerial vehicles (Drones), which allows the journalists to take photos from different angles for the news events such as the volcanic eruptions, war-torn villages and natural disasters.

Despite significant progress in recent years, the therapeutic approach of the multiple different forms of human cancer often remains a challenge. Besides the well-established cancer surgery, radiotherapy and chemotherapy, immunotherapeutic strategies gain more and more attention, and some of them have already been successfully introduced into the clinic. Among these, immunotherapy based on natural killer (NK) cells is considered as one of the most promising options. In the present review, we will expose the different possibilities NK cells offer in this context, compare data about the theoretical background and mechanism(s) of action, report some results of clinical trials and identify several very recent trends. The pharmaceutical industry is quite interested in NK cell immunotherapy, which will benefit the speed of progress in the field.

Abstract Increases in the frequency of extreme rainfall occurrence have emerged as one of the more consistent climate trends in recent decades, particularly in the eastern United States. Such changes challenge the veracity of the conventional assumption of stationarity that has been applied in the published extreme rainfall analyses that are the foundation for engineering design assessments and resiliency planning. Using partial duration series with varying record lengths, temporal changes in daily and hourly rainfall extremes corresponding to average annual recurrence probabilities ranging from 50% (i.e. the 2-year storm) to 1% (i.e. the 100-year storm) are evaluated. From 2000 through 2019, extreme rainfall amounts across a range of durations and recurrence probabilities have increased at 75% of the long-term precipitation observation stations in the Middle-Atlantic region. At about a quarter of the stations, increases in extreme rainfall have exceeded 5% from 2000 through 2019, with some stations experiencing increases in excess of 10% for both daily and hourly durations. At over 40% of the stations the rainfall extremes based on the 1950-1999 partial duration series show a significant (p >0.90) change in the 100-yr ARI relative to the 1950-2019 period. Collectively the results indicate that given recent trends in extreme rainfall, routine updates of extreme rainfall analyses are warranted on 20-year intervals.
