In recent years, Kabul city's rapid urbanization has adversely affected the urban land cover, such as surface water bodies and croplands. Surface resources are threatened due to overpopulation in city either qualitatively or quantitatively, also croplands being lost with development of activities through city. To monitor assess changes accurately, we classified area using satellite images both ...
For centuries, game meat has been an important source of proteins, vitamins and minerals in the human diet. Interest for during last few decades is increasing, mainly due to lower ecological footprint a preferred chemical composition comparison domestic animals. In recent years, Europe facing overpopulation wild boars, which affects availability wider niche consumers. Therefore, great alternati...
Urban space is a dynamic system influenced by many factors. The formation of the transport structure in city determines type planning that forms spatial framework, and then functional organization territories determined. This allows us to create an effective urban space. But cities are changing, their needs, definitions, especially functions so modifying existing approaches pressing issue for u...
When mutual developed and developing world accusations of overpopulation and overconsumption are analyzed, several levels of confusion can be pointed out. Since proposals to change global patterns of consumption come from different and even conflicting sources, they should be the object of careful consideration. Changes in consumption influence employment, and therefore they could be detrimenta...
For the development of rural environment, education should be taken on priority as it is the most important factor. Education is the basis for creativity and foresightedness that triggers change; it helps in economic growth, quality of life and quality of human resource. Education takes us away from tradition backwardness, darkness, poverty, misery and overpopulation to enlighten, prosperity an...
Perlecan is a heparan-sulfate proteoglycan abundantly expressed in pericellular matrices and basement membranes during development. Inactivation of the perlecan gene in mice is lethal at two developmental stages: around E10 and around birth. We report a high incidence of malformations of the cardiac outflow tract in perlecan-deficient embryos. Complete transposition of great arteries was diagno...
Urban problems—such as resources depletion, environment pollution and waste generation—usually occur during rapid urbanisation processes, especially in mega-urban agglomerations. Finding solutions to sustainable urban development is a global research interest, and urban metabolism is an effective approach to analysing the socio-economic system and ecosystem. In this study, three cities in the J...
Although the concept that cancers originate from stem cells (SC) is becoming scientifically accepted, mechanisms by which SC contribute to tumor initiation and progression are largely unknown. For colorectal cancer (CRC), investigation of this problem has been hindered by a paucity of specific markers for identification and isolation of SC from normal and malignant colon. Accordingly, aldehyde ...
Although the initial formulation of modern concepts of adaptive radiation arose from consideration of the fossil data, rigorous attempts to identify this phenomenon in the fossil record are largely uncommon. Here I focus on direct evidence of the diet (through tooth-wear patterns) and ecologically-relevant traits of one of the most renowned fossil vertebrates-the Miocene ruminant Hoplitomeryx f...
