On the night of February 21st, 2010, the county road 724 that connects the Malu cu Flori-Pucheni village was destroyed by a violent landslide, isolating it. In a few hours the road, together with the electrical, phone and water systems were moved downstream 30m along 100 meters. The area has been known for more than 100 years as being affected by landslides, which have appeared immediately after massive deforestation, regularly engaging local roads, house hold settlements. After the sliding in 1970, a series of wo...

The principal tool used for the implementation of spatial policy in Polish communes is a local spatial management plan. It is an act of local law and its provisions are binding in respect of the purpose of land development and the way it is achieved, development conditions and localisation of public aim investments. All actions undertaken by the commune authorities must be carried out in a manner which is both socially and economically efficient, in compliance with the requirements of environmental protection. The...

Different species of plant aphids can be found in greenhouses worldwide, depending on the crop and climatic condition. Aphids may occur in large colonies on new growth, the base of buds, or the undersides of mature leaves. The aphids damage the plants directly by sucking plant sap from the plant tissues and indirectly as a vector of different plant viruses. The aim of this paper was to identify the most abundant aphid species causing damages to pepper cultivated in greenhouses. The two year experiment (2015 and 20...

Employing models in science teaching is considered to be fundamental for an authentic learning of science. In fact, the use of models in science classes may help students in the development of a better understanding of scientific content, of inquiry skills and also in the understanding of the nature of models and of the nature of science. Also, the analysis of historical models may also play a major contribution to the understanding of scientific knowledge construction and development. Moreover, in geoscience educ...

To increase the efficiency of conversion of plant raw materials, a search for new enzymes is required. The hydrolysis of xylan using industrial xylanases is widely used in the production of bleached cellulose. However, an increase in activity, selectivity and thermostability of enzymes is relevant for modern biotechnology. Recently, the sources of bacteria that have important practical significance are very diverse: from sea depths to volcanoes. But there are also accessible habitats, for example deposits of waste...

Genesis of the Uralian oxide-silicate supergene nickel deposits remains disputable. There are supergene and polygenic hypogenous model of their origin. The second model usually involves supergene and hydrothermal-hypogenous stages of formation. To solve this problem isotope ratio 87Sr / 86Sr was determined for the first time for the Ufalei and Sakhara supergene nickel deposits. The obtained data on the 87Sr / 86Sr isotopic ratio in samples from ore zones are divided into two groups, which indicate two sources of s...

During the last decades, scientists have confirmed that global climate change is a result of human activities, aspects emphasized by long-term observation on different climate elements. Rural people, who make up approximately 40% of the global population, are generally more vulnerable to the adverse consequences of climate change. Despite the growing knowledge base on climate change and its impacts, much remains to be understood about the linkages between climate change and rural development. Climate change affect...

The examined materials were compared in the regard to their toxicity of the combustion products based on the carbon m...

Every day more than 60 tons of hydrolyzed lignin are produced only on one bioethanol manufacturing factory, 25000 tons per year. More than 1 million tons of lignin is produced by wood-recycling factories worldwide, which is being combusted to compensate energy costs or just stored as a waste. We suppose that there is a more sufficient way of its recycling and provide another way of lignin use, assuming the pyrolysis process as one of the pretreatment methods of its reproduction into more favorable derivatives. Pyr...

The presence of metals in aquatic environment is known to cause several health problems to animals and human beings. The levels of heavy metals in wastewater and drinking water must be reduced to the maximum permissible concentration. Clays are abundant and inexpensive layered alumino-silicate minerals that have adsorbent properties. In general, chemical species can interact with clays either by ion exchange or physisorption, both being reversible processes. Among the mineral clays, smectites, especially montmoril...
