Landless rooftop farming is an artificial cultivation on the roof which uses organic solid or liquid media called solution culture “media culture” or water culture “hydroponics”. Media culture and hydroponics has been used sporadically throughout the world in rooftop and tissue culture also has been used  the world as commercial means of growing both food and ornamental plants. It supplies fresh vegetables in countries with limited arable land as well as in small countries with large populations. Plants grown by hydroponics have concisely superior quality, high yield, rapid harvest, and high content, at present it is used widely in research facilities as a technique for studying plant nutrition. Gravel or sand is sometimes used in soilless systems to provide plant support, and retain some nutrients and water. The retention and water can be for their improvement through the used materials, but others  such as rice hulls, bagasse, sedge peat, and sawdust are used sometime as constituents in soilless mixture straw bales have been used as the growing medium in England and Canada. Rockwool (porous stone fiber) is used in Europe. Since the major constituent of the media in artificial growing systems may be solid or liquid, it is appropriate to use the term soil culture in reference to this general type of growing system and reserve the term hydroponics for those in which water is the principal constituent. Soilless organic media preparation and use has a tremendous effect in land less culture. It is basically used in Rooftop vegetable cultivation.

SummaryThe preparation of a monoclonal antibody (MAB) against high molecular weight (HMW) urokinase light chain (20,000 Mr) is described. This MAB was immobilized and the resulting immunosorbent was used to isolate urokinase starting with an impure commercial preparation, fresh urine, spent tissue culture media, or E. coli broth without preliminary dialysis or concentration steps. Monospecific antibodies appear to provide a rapid single step method of purifying urokinase, in high yield, from a variety of biological fluids.

AbstractBiomass gasification, especially distribution to power generation, is considered as a promising way to tackle global energy and environmental challenges. However, previous researches on integrated analysis of the greenhouse gases (GHG) abatement potentials associated with biomass electrification are sparse and few have taken the freshwater utilization into account within a coherent framework, though both energy and water scarcity are lying in the central concerns in China’s environmental policy. This study employs a Life cycle assessment (LCA) model to analyse the actual performance combined with water footprint (WF) assessment methods. The inextricable trade-offs between three representative energy-producing technologies are explored based on three categories of non-food crops (maize, sorghum and hybrid pennisetum) cultivated in marginal arable land. WF results demonstrate that the Hybrid pennisetum system has the largest impact on the water resources whereas the other two technology options exhibit the characteristics of environmental sustainability. The large variances in contribution ratio between the four sub-processes in terms of total impacts are reflected by the LCA results. The Anaerobic Digestion process is found to be the main contributor whereas the Digestate management process is shown to be able to effectively mitigate the negative environmental impacts with an absolute share. Sensitivity analysis is implemented to detect the impacts of loss ratios variation, as silage mass and methane, on final results. The methane loss has the largest influence on the Hybrid pennisetum system, followed by the Maize system. Above all, the Sorghum system demonstrates the best performance amongst the considered assessment categories. Our study builds a pilot reference for further driving large-scale project of bioenergy production and conversion. The synergy of combined WF-LCA method allows us to conduct a comprehensive assessment and to provide insights into environmental and resource management.

The practice of treating the environment with disdain has gradually become unfashionable. Yet in many developing nations, Nigeria among them, environmental education and awareness campaigns remain something regarded as unnecessary. According to Berry (1993: 158):The term “sustainable development” has become a shibboleth of governments and industries, to present a respectful image to a society that is becoming even more strident in its concern for the environment. It is a concept that was projected onto the world by the Stockholm Conference of 1972, and has been carried ever since by the United Nations Environment Programs (UNEP), the World Conservation Union (IUCN), and the World Wildlife Fund for nature (WWF) in their world conservation strategy. It has the ring of truth and worldwide acceptance, but it is poorly understood by those who use it.

Virtual Influencers (VIs) are computer-generated characters, many of which are often visually indistinguishable from humans and interact with the world in the first-person perspective as social media influencers. They are gaining popularity by creating content in various areas, including fashion, music, art, sports, games, environmental sustainability, and mental health. Marketing firms and brands increasingly use them to capitalise on their millions of followers. Yet, little is known about what prompts people to engage with these digital beings. In this paper, we present our interview study with online users who followed different VIs on Instagram beyond the fashion application domain. Our findings show that the followers are attracted to VIs due to a unique mixture of visual appeal, sense of mystery, and creative storytelling that sets VI content apart from that of real human influencers. Specifically, VI content enables digital artists and content creators by removing the constraints of bodies and physical features. The followers not only perceived VIs' rising popularity in commercial industries, but also are supportive of VI involvement in non-commercial causes and campaigns. However, followers are reluctant to attribute trustworthiness to VIs in general though they display trust in limited domains, e.g., technology, music, games, and art. This research highlights VI's potential as innovative digital content, carrying influence and employing more varied creators, an appeal that could be harnessed by diverse industries and also by public interest organisations.

Adaptation strategies to the climate change include measures that can be taken to take account of the new climatic conditions. This paper aims at assessing the effects of climate change on environmental sustainability. This sustainability constitutes a major problem in many countries and regions around the world that experience industrial pollution, degradation of land as well as natural disasters caused by the global warming. The paper shows that adaptation strategies are often parallel strategies that can be integrated simultaneously with the management of natural resources. They can make resources more efficient and resilient to climate change. The paper shows that reducing the carbon footprint by more than 50 percent by 2030 and eliminating it by 2050 might be a viable solution how to tackle the climate change and support the environmental sustainability.

National Stereotypes

The issue of national stereotypes requires, in the situation of dynamic changes in Europe and in the world, to update and consider new sources. A new area for tracking changes in the mutual perception of neighbouring nations are the texts of media culture, combining verbal and visual code. In the article, I elaborate on the legitimacy of using such intersemiotic messages, such as memes, demotivators, posters, advertisements, to study stereotypes. The Internet stereotype of a Pole functions on two levels, language and imagination, therefore it is a continuation of the national stereotype in a changed form.

The largest countries of the world are inevitably involved in various global processes, both natural and socio-economic. These countries have common features and characteristic differences in the state of their territorial resources; the study of these characteristics is of interest for the global prospects of sustainable development. A large territory provides a variety of natural conditions and resources for the country; however, not in all countries it is possible to effectively use them in the economy throughout the all country. An analysis of their territorial resources was carried out for the six largest countries of the world according to the following parameters: area, efficiency, environmental load on the territory of the country, number, density, forecast of population growth or decline for 2050, main agricultural land (arable land, pastures, the provision of the population, degradation and pollution of the soils), forest resources (including security per capita, share in the area of countries), fresh water resources (including per capita provision and availability), greenhouse gas emissions, including per capita, the proportion of mammals endangered, proportion of areas of preserved ecosystems. The data obtained was displayed on the maps; a common legend is built for them in tabular form. A number of other parameters of the state of territorial resources and the environment were also studied. In the process of research, the most important cities of these countries were also studied and diagrams showing their similarities and differences in a number of indicators were constructed: area, population and population density, time of foundation, climatic and landscape parameters, the presence of UNESCO World Heritage Sites, high-rise construction parameters. The developed methodology is effective for assessing a variety of data on territorial resources that can be used to build models of sustainable development of the largest countries and regions of the Earth.

Term Monitoring

Rational use of natural resources and preservation of environment in good conditions are the basis of stable state of the ecosystem. Mountain soil erosion is the most common process of degradation. Soil protection from erosion is becoming a global problem in the world, and in Uzbekistan, in particular. Natural conditions of the region create a potential danger of soil erosion. The reason for its manifestation is the misuse of land, non-compliance with necessary requirements for soil protection. In most cases, it is due to the location of homesteads and crops on erosion-prone soils that poorly protect soil from erosion, improper cultivation of soils on arable land, unregulated grazing of pastures, and damage to soil protective plantations.
