Study on the pollution mechanism of drinking water source water to ultrafiltration membrane

Research Article of International Journal of Natural Science and Reviews Study on the pollution mechanism of drinking water source water to ultrafiltration membrane Lv Jianxing, Geng Anchao, Wu Lingbing, Qiao Sha, Li Liuhuan Shanghai Maritime University, College of Marine Science and Engineering,shanghai, 201306,China The effects of particulate matter (represented by humic acid, kaolin and algae) on ultrafiltration membranes in micro-polluted water sources were investigated, and the mechanism of ultrafiltration membranes was further understood with the change of membrane flux and transmembrane pressure difference. The results showed that the removal rate of kaolin and algae by UF membrane was over 99%, while the removal rate of humic acid was only about 72%. Moreover, the extent of UF membrane fouling caused by humic acid was larger than that caused by kaolin and algae. The higher the concentration of humic acid, the more serious the membrane fouling was. Ultrafiltration membranes contaminated by humic acid were washed by 0.05mol/L NaOH alkali and 0.05mol/L HCL acid. The permeability of the membranes was restored to 91.24% of the cleaned surface, which was better than that of pure water, sodium hypochlorite and sodium hydroxide. It can provide better guidance for choosing appropriate cleaning agents for ultrafiltration membrane fouling. Keywords: Ultrafiltration membrane; Humic acid; Kaolin; Algae ...

The Use of Play as a Tool for Community Science Teaching

Research Article of International Journal of Natural Science and Reviews The Use of Play as a Tool for Community Science Teaching Narciso, M.L1 Souza, F.L2 Lucas, L.A.S3 SILVA, E.V4 Anjos FB.R4 Ferreira Neto, J5. Jimenez, G.C5 Bastos, D.M.S5 1,2,3Estudante do Curso de Ciências Biológicas – UFPE;4Pesquisador do Departamento de Histologia e Embriologia-UFPE, 5Pesquisador do Departamento de Morfologia e Farmacologia-UFRPE The teaching of science has, over the last years, gained space in academic discussions, due to the need to use more attractive methods and strategies for students. The tendency to combine the playful with the science teaching has been gaining prominence in the classrooms, and it can be observed the use of educational games, comic books, cartoons, plays, drawings. Clown therapy involves a professional who uses techniques to show and generate health from other angles of life. Laughter therapy is widespread in hospitals, this practice has become relevant for improving treatment in hospitalized children. This artistic resource is taken in schools, kindergartens and NGOs and enables personal development, allowing the critical spirit and the exercise of citizenship to be broadened. The objective of this work was to develop art workshops that connect social, ecological and cultural aspects, seeking the use of the ludic in science teaching. This work was carried out in an NGO located in Bode community, Pina neighborhood in Recife - PE, with children from the local community, between 5 and 12 years old. Teaching activities were selected to stimulate children’s reflective and scientific thinking associated with popular knowledge. In order to make the sustainability workshop a previous conversation was held with the children, with the purpose of knowing the group’s knowledge about the theme worked. Then toys were made of recyclable material, such as: pet bottle carts; Bookmark pages with popsicle stick and straw flute. For the insect ...

Plant Species Diversity for Climate Change Adaptation and Mitigation

Review Article of International Journal of Natural Science and Reviews Plant Species Diversity for Climate Change Adaptation and Mitigation Bikila Mengistu Oromia Agricultural Research Institute, Sinana Agricultural Research Center, P.O. Box 208, Bale-Robe, Ethiopia Climate is one of the most important factors that influence and determine the behavior, abundance and distribution of species, as well as having a strong influence on the ecology of habitats and ecosystems structure. Changes in the behavior, abundance and distribution of species are linked to climate. Diversity and plant species are highly interlinked and the relationship between biodiversity and climate change should be explored from several perspectives. This variety provides the building blocks to adapt to changing environmental conditions which are caused due to climate change. Conserved habitats can remove carbon dioxide from the atmosphere, thus helping to address climate change by storing carbon in the plant biomass. Climate is one of the major limiting factors which determine the survival and growth of plants. The conservation and restoration of biodiversity and ecosystem services can play a key role in helping societies to adapt to climate change. Biodiversity is affected by climate change, but biodiversity, through the ecosystem services and function it supports, also makes an important contribution to both climate-change mitigation and adaptation. Maintenance of agro-biodiversity and carbon sequestration through the process of photosynthesis is the two important and complementary environmental services of agro-ecosystems. Climate change affects biodiversity and one of the causes of biodiversity loss. At the same time climate change will accelerate further if biodiversity and ecosystems are not effectively protected. Generally due to the variation of genetic makeup within pants, different plant species diversity plays a great role in climate change adaption and mitigation process. Keywords:Adaptation, carbon, climate change, diversity, mitigation ...

Thermodynamics of the origin of life, evolution, and aging

Review Article of International Journal of Natural Science and Reviews Thermodynamics of the origin of life, evolution, and aging G. P. Gladyshev Russian Academy of Arts; International Academy of Creative Endeavors; N.N. Semenov Institute of Chemical Physics, Russian Academy of Sciences, 117977 Moscow, Kosygin, 4 The main provisions of hierarchical thermodynamics created on the basis of Gibbs thermodynamics are presented. The thermodynamic theory of the origin of life, its evolution and the aging of living beings is presented. The theory considers the change in the specific Gibbs function of the formation of structures of different hierarchies, that is, the change in the comparative stability of these structures in the course of their evolutionary transformations. The described approach should be considered structural kinetic thermodynamics, which allows us not to consider any kinetic mechanisms of processes in the evolution of various hierarchical structures. It is asserted that the principle of substance stability determines the direction of the processes of the origin of life and its evolutionary transformations. The thermodynamic theory of aging and thermodynamic nutrition allows predictions concerning healthy life and its duration. It is shown that hierarchical thermodynamics is the physical foundation of expanded Darwinism. All the conclusions and predictions of the theory are confirmed by numerous observations and experimental facts. Keywords: thermodynamics, hierarchy, origin of life, evolution, chemical evolution, aging, Darwinism, natural design ...
