Currently, there is either no or scant information that describes the influence of climate changes and variability to watermelon production in Zanzibar. Thus, this study aimed to determine the influence of climate variability on the quantity of watermelon production in Zanzibar. The study used both primary and secondary datasets, which include the anecdotal information collected from interviewers’ responses from four districts of Unguja and Pemba, and climate parameters (rainfall, maximum and minimum temperature (Tmax and Tmin) acquired from Tanzania Meteorological Authority (TMA) at Zanzibar offices. Pearson correlation was used for analyzing the association between watermelon production and climate parameters, while paired t-test was applied to show the significance of the mean differences of watermelon and climate parameters for two periods of 2014-2017 and 2018-2021, respectively. Percentage changes were used to feature the extent to which the two investigated parameters affect each other. The anecdotal responses were sorted, calculated in monthly and seasonal averages, plotted and then analyzed. Results have shown a strong correlation (r = 0.8 at p ≤ 0.02, and r = 0.7) between watermelon production, Tmax and rainfall during OND, especially in Unguja, as well as Tmin during JJA (i.e. r = - 0.8 at p ≤ 0.02) in Pemba. Besides, results have shown the existence of significant differences between the means of watermelon production and climate parameter for the two stated periods, indicating that the climate parameters highly affects the watermelon production by either enhancing or declining the yields by 69% - 162% and 17% - 77%, respectively. Moreover, results have shown that respondents were aware that excess temperature intensity during dry periods can lead to high production costs due number of 展开更多

Two marl (Asl Marl) and shale (Hawara Formation) sections of possible source enrichment are detected above and below this oil sand section, respectively. This study aims to identify the content of the total organic carbon based on the density log and a combination technique of the resistivity and porosity logs (Δlog R Technique). The available geochemical analyses are used to calibrate the constants of the TOC and the level of maturity (LOM) used in the (Δlog R Technique). The geochemical-based LOM is found as 9.0 and the calibrated constants of the Asl Marl and Hawara Formation are found as 11.68, 3.88 and 8.77, 2.80, respectively. Fair to good TOC% content values (0.88 to 1.85) were recorded for Asl Marl section in the majority of the studied wells, while less than 0.5% is recorded for the Hawara Formation. The lateral distribution maps show that most of the TOC% enrichments are concentrated at central and eastern parts of the study area, providing a good source for the hydrocarbons encountered in the underlying Asl Sand section.展开更多

Even though Britain was excluded from the list of embargoed nations, the impact of the embargo for the British economy, especially the fear of insufficient energy in the industrial sector, was real. Consequently, Britain had to implement an effective plan to face the oil crisis. She revised her diplomatic strategy and even considered launching military action to protect her interests in the Arab world. The research is based upon archival documents from The National Archives of England and Wales.展开更多

The victory of the October Revolution turned socialism from an ideal into a reality and brought Marxism to a new stage： the stage of Leninism. The October Revolution changed the direction of world history and the Chinese revolution, a continuation of the October Revolution, became part of the proletarian-socialist world revolution. Any talk about Marxism in isolation from China＇s characteristics is merely Marxism in the abstract, Marxism in a vacuum. We can put Marxism into practice only when it is integrated with the specific characteristics of our country and acquires a definite national form. Deng Xiaoping Theory comes down in one continuous line from Leninism and Mao Zedong Thought and is Marxism in practice with the characteristics of the times and national traits. The magnificent achievements in the development of contemporary Chinese society are the outcome of unwavering adherence to and development of socialism with Chinese characteristics. In the context of economic globalization, we are still living in a transitional time from capitalism to socialism, an era started with the October Revolution. The 21 st century will see the rejuvenation of socialism, for the replacement of capitalism by socialism is an inevitable trend of world history.展开更多
