Schistosomiasis has been described as “one of the most devastating diseases of mankind, second only to malaria in its deleterious effects on the social and economic development of populations in many warm areas of the world.” The disease is world wide and is probably spreading faster and becoming more intense than the overall research efforts designed to provide the basis for countering it. Moreover, there are indications that the development of water resources and the demands for increasing cultivation and food in developing countries may prevent adequate control of the disease, and thus, the number of infections are increasing.Our knowledge of the basic biology of the parasite causing the disease is far from adequate. Such knowledge is essential if we are to develop a rational approach to the effective control of human schistosomiasis. The miracidium is the first infective stage in the complex life cycle of schistosomes.

INTRODUCTION: Schistosomiasis has been described as “one of the most devastating diseases of mankind, second only to malaria in its deleterious effects on the social and economic development of populations in many warm areas of the world.” The disease is worldwide and is probably spreading faster and becoming more intense than the overall research efforts designed to provide the basis for countering it. Moreover, there are indications that the development of water resources and the demands for increasing cultivation and food in developing countries may prevent adequate control of the disease and thus the number of infections are increasing.Our knowledge of the basic biology of the parasites causing the disease is far from adequate. Such knowledge is essential if we are to develop a rational approach to the effective control of human schistosomiasis. The miracidium is the first infective stage in the complex life cycle of schistosomes. The future of the entire life cycle depends on the capacity and ability of this organism to locate and enter a suitable snail host for further development, Little is known about the nervous system of the miracidium of Schistosoma mansoni and of other trematodes. Studies indicate that miracidia contain a well developed and complex nervous system that may aid the larvae in locating and entering a susceptible snail host (Wilson, 1970; Brooker, 1972; Chernin, 1974; Pan, 1980; Mehlhorn, 1988; and Jones, 1987-1988).

The Web

Since it was first formally proposed in 1990 (and since the first website was launched in 1991), the World Wide Web has evolved from a collection of linked hypertext documents residing on the Internet, to a "meta-medium" featuring platforms that older media have leveraged to reach their publics through alternative means. However, this pathway towards the modernization of the Web has not been entirely linear, nor will it proceed as such. Accordingly, this paper problematizes the notion of "progress" as it relates to the online realm by illuminating two distinct perspectives on the realized and proposed evolution of the Web, both of which can be grounded in the broader debate concerning technological determinism versus the social construction of technology: on the one hand, the centralized and ontology-driven shift from a human-centred "Web of Documents" to a machine-understandable "Web of Data" or "Semantic Web", which is supported by the Web's inventor, Tim Berners-Lee, and the organization he heads, the World Wide Web Consortium (W3C); on the other, the decentralized and folksonomy-driven mechanisms through which individuals and collectives exert control over the online environment (e.g. through the social networking applications that have come to characterize the contemporary period of "Web 2.0"). Methodologically, the above is accomplished through a sustained exploration of theory derived from communication and cultural studies, which discursively weaves these two viewpoints together with a technical history of recent W3C projects. As a case study, it is asserted that the forward slashes contained in a Uniform Resource Identifier (URI) were a social construct that was eventually rendered extraneous by the end-user community. By focusing On the context of the technology itself, it is anticipated that this paper will contribute to the broader debate concerning the future of the Web and its need to move beyond a determinant "modernization paradigm" or over-arching ontology, as well as advance the potential connections that can be cultivated with cognate disciplines.

How teachers perform and react to the world-wide pandemic and how the epidemic affects an education system may also be used as new conditions to consider the way to enhance SDG4 in developing countries. Regarding that concern, this study investigated 294 teachers’ perspective on their teaching effectiveness and satisfaction during COVID-19. The findings underlined the significant roles of support from various stakeholders, school readiness toward digital transformation, and teachers’ anxiety over teacher satisfaction. Notably, teachers’ newly absorbed technological and pedagogical skills do elevate their teaching effectiveness but do not lead to higher satisfaction during the pandemic.

Do So

Poverty is no longer fashionable even in the less developed countries of the world. The world has deemed poverty-ridden regions of the world as ‘anathema', forbidden, and ignoble. At the same time ways to get out of the menace are regularly strategised over a period of time. The developed countries of the world had been able to nip poverty to the bud significantly, but the developing countries still have a lot to do so as to overcome the menace. Poverty in the developing countries operates in a cycle of repetitions. This makes it difficult to curtail. How can poverty be reduced in the developing countries? This study reveals the reason while poverty has become a domestic phenomenon in developing countries and the way forward. The theory on poverty is evaluated alongside the present economic situation in Africa. The cycle of poverty, which includes the social cycle of poverty (SCP), political cycle of poverty (PCP), and the economic cycle of poverty (ECP), are examined. This study analyses the strategies to break the cycle of poverty in Africa and other developing countries.

The Belt And Road

Since its launch in late 2013, China’s Belt and Road Initiative (BRI) has achieved many tangible results that may have lasting effect on the social and economic development of host countries and on the geopolitical dynamics of the world. Its emergence in international political discourse is changing the basic thinking and logic of traditional geopolitical competition. While Western countries tend to interpret the BRI as part of China’s hidden geopolitical strategy to ultimately rule the world, Chinese and most developing nations see it as China’s international cooperation strategy to enhance global connectivity, communication and cooperation, so as to foster a more balanced and equitable world system. To maintain a favorable international environment for further progress of the BRI, China needs to better explain the details concerning the initiative as well as its role in the country’s grand strategy of peaceful development. Meanwhile, China must keep striving to match its words with its deeds in global arenas, so as to win more trust and support from the international community in jointly implementing the initiative.

It will be presented the German Bertelsmann-Foundation which belongs to one of the world-wide biggest media companies. The enterprise-foundation exerts an important influence on several social reform movements in Germany. Doing this, the Bertelsmann-Foundation succeeds in integrating associations, parties and personalities representing nearly the entire range of society. This raises the question, weather the foundation is a political neutral institution as it claims to be. By having a critical look at the foundation-project „intellectual orientation“ the social character of production of ideas by the Bertelsmann-Foundation will be demonstrated. It can be shown, the role of the Bertelsmann-Foundation is that of a mediator, transforming different interests into a new kind of social corporatism.

The setting up of anesthesia units and any future planning in this field has to be considered in the context of the social and economic development of the country. The situation requires a different attitude towards the handling of anesthesia, where malnutrition, kwashiorkor and parasites are the dominant diseases. One sixth of the world's population is permanently undernourished, and the figure might even be higher in many “developing countries.”Problems of an esthesiain most areas in Africa include: (1) insufficient supply of drugs; (2) inadequate equipment; (3) lack of anesthetic manpower; and (4) underestimation of the importance of anesthesia.
