 Determinants of the Intention to Adopt the Social Network Whatsapp in a Professional Situation: An Empirical Study in Cameroon The coronavirus pandemic has further democratized the use of social media. Faced with health restrictions and physical distancing, workers have seen their working methods completely transformed. The objective of this work was to identify the predictors of the intention to adopt the social network Whatsapp by Cameroonian workers in a professional situation. A questionnaire based on the Unified Theory of Acceptance and Use of Technology was administered online to a sample of 358 subjects. The data collected were analyzed on SPSS 20.0. The multiple regression test was applied. The significance threshold was set at p<0.05. The results show that 42% of the variance in the intention to adopt the social network Whatsapp by Cameroonian workers in a professional situation was explained by the feeling of perceived effectiveness, ease of use, influence of colleagu...

 Sustainable Development: Reality Or Myth? Since the United Nations Environment Conference in Stockholm (1972), the concept of sustainable development has steadily made its way among individual scientists and international organizations. The apotheosis of this development was the adoption by the United Nations in 2015 of the 17 Sustainable Development Goals. However, many scientists and politicians were skeptical about the concept of sustainable development, since the results of implementing sustainable development in different countries were far from expected. Many decisions taken at the level of the UN and other international organizations turned out to be unfulfilled. In my opinion, as well as some other Russian scientists, the concept of sustainable development is an unrealistic project, it is a myth, although it is very positive and humane. Sustainable development goals can be achieved only by the most economically developed countries entering the era of post-industrialism. In...

 From Bronchial Asthma to Tuberculosis: Unravelling the Cytokine-Macrophage Axis in Diverse Diseases Cytokines, tiny proteins secreted by cells, play a critical role in mediating communication and interactions between cells. They also function as immunomodulating agents, adjusting immune responses. When released into the bloodstream or tissues, cytokines bind to specific receptors on target immune cells, triggering cellular responses. Cytokines are implicated in various diseases, including asthma, COPD, HIV infection, and multiple sclerosis. This review delves into the intricate interplay between cytokines and macrophages, focusing on their roles in inflammation and the immune response. Macrophages, which are scavenger cells of the immune system, exhibit remarkable heterogeneity, reside in diverse tissues, and play crucial roles in both innate and acquired immunity. They can be activated for proinflammatory or anti-inflammatory functions, contributing to tissue destruction or regen...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...

 Lateral Rock Characteristic Evidence of Hydrocarbon Restoration from Post-Stack Impedance Inversion: A Case Study of ZED-field Offshore Niger Delta Lateral predictions of rock properties that are descriptive of a reservoir have been studied using a model-established seismic inversion approach that was used to convert input seismic data into an acoustic impedance structure to optimize hydrocarbon restoration in the field. This was actualized by integrating wireline logs and 3D post stack seismic data procured from ZED-Field offshore Niger Delta. The inversion system employed in this study comprises of forward modelling of reflection coefficients starting with a low-frequency impedance model induced from well logs and convolution of the reflection coefficients with the source wavelet extracted from the seismic input. P-impedance analysis at reservoir C5000 delineated from the control well gave a near perfect correlation of 0.998109 (≈ 99.8 %) between the original P-impedance log, in...

Are Generational Psychological Traits Basic in the Practice?  We are dealing with a very important and sensitive issue of our days, the generational differences and characteristics within businesses. In fact, it’s about a qualitative presentation of HR within the Theory of the Firm. Knowing the characteristics of each generation, altogether with appropriate skills and know-how, both employees and entrepreneurs/CEOs, the positive results are granted, prosperity and return are achieved. Qualitative analysis is used, due to the fact we face psychological traits and behaviours based on them. Discussions, interviews, papers in media are used, along with my own expertise in higher education. Research sources mean, essentially, the opinions and training papers of some-well-known consultancy firms in the field, such as McKinsey, Deloitte, KPMG, which present sound materials, courses, based on the empirical observations of what is happening in HR field nowadays. As conclusions, generational...
