Farmers living in the near by forest villages fullfilled their living needs mainly through exploiting the forest resources. Controlled forest exploitation created serious forest degradation. The annual forest degradation rate was 2 to 6 million hectares. In this relation the objectives of this study were to asses the relationship of farmer’s characteristics and their competencies in forest conservation. The population of this study was four hundreds farmers living in 12 village near the national forest park. Data was collected from may to october 2005. Data obtained were analized by Kendall W Concordance procedure and SEM. The result pointed out that farmers lacked competencies in both farm and forest conservation.

The article is devoted to the problems of disturbed lands that are part of urban territories, the need for reclamation and the creation of recreational spaces based on them. There are a large number of quarries on the territory of the Belgorod region, many of which are no longer functioning and they need to be transformed. The work in this direction entails an improvement in the environmental situation, increases the quality of the urban environment and makes these objects attractive for investment. The authors consider the main factors affecting the reclamation of the territory, analyze the types of soil and identify the relationship of geodesy with the architectural component of reclamation, present foreign and domestic experience in solving problems related to disturbed lands, comply a table of the main quarries of the Belgorod region in order to identify features characteristic of this region. As a result of the research, proposals and methods are put forward, taking into account regional peculiarities, for the reclamation of a chalk quarry in order to create a recreational space and then integrate it into the forest park framework in Belgorod, which will lead to an improvement in the environmental situation and aesthetic perception of the city as a whole.

The significance of afforestation in Serbia is high because only in this way the forest area can be increased and brought to the level which corresponds to the demands of the population. This is also indicated by the content of some documents, such as 'Professional base for the design of the National Forest Action Programme', which emphasises this problem from the very beginning. Special significance is assigned to afforestation with Austrian pine and Scots pine, which are most frequently applied in the afforestation of the most unfavourable terrains. This study analyses the scope of afforestation over the period 1961-2007, the percentage of Austrian pine and Scots pine and the relationship of the afforested areas, and generates the forecasts of the changes in the future period. In this way, the socialeconomic significance of afforestation can be assessed from the aspect of satisfying the objectives of forest policy, and particularly of afforestation with Austrian pine and Scots pine, as the specific tree species.

The concept of National Forest Park (NFP) is mainly used in mainland China. Originating in 1982, NFP embodies a “top-down” concept and associated program launched by the Chinese government. It is aimed at promoting forest-based tourism and economic development under the premise of protecting forest resources. After 30 years of development, NFPs have made great achievements in protecting specific forest resources, promoting forest-based tourists, promoting regional economic development, and they have gained popularity worldwide. However, due to the fast pace of NFP expansion, lack of predictable planning and innovative thinking, and ineffective governance, some problems like overexploitation, scenic pollution, monotonous development patterns, and ecological degradation associated with NFP constrain its sustainable development. In order to solve these problems effectively, a holistic review of the status of NFPs in China is needed. To help meet this need, the origin, evolution, and current status of NFPs in China were analyzed. The presented research also included retrospective analyses of challenges and opportunities for NFPs sustainable development in China. Results show that from 1982 to 2015, the number of NFPs grew dramatically, and this development occurred in four phases. In addition, NFP development has been unbalanced in regional distribution. When analyzing the evolution of NFPs, the main issues to date have included failure to implement Master Plans in practice, unclear supervisory responsibilities, ambiguous classification, unbalanced distribution, destruction of natural resource and ecosystems, insufficient cultural protection, weak awareness of nature education, lack of resource statistics, monotonous planning, and weak marketing. Study findings can contribute to promoting the sustainable future development of NFPs and support the forest-based tourism industry.

Abstract A study of serum and plasma of patients receiving dicumarol reveals that a good correlation exists between the "degradation rate" of "prothrombin-converting factor" in the serum and the concentration of prothrombin in the plasma. As prothrombin concentrations falls, the rate of degradation of "prothrombin-converting factor" becomes slower, while a rise in prothrombin concentration is associated with an accelerated "degradation rate."

Near forest village residents was one of the main forest share holders. So, they should be involved in various forest conservation efforts. Their involvements not only in activities to keep out people from illegal cutting of the forest trees or to put off forest fire, but also in replanting the forest and in other conservation activities. To improve these people welfare, a study on the villagers’ participation in forest conservation was needed. In this conjunction, the objectives of this study were: (1) to determine the villagers’ distributions on their selected characteristics, (2) to identify the villagers’ participation in the forest conservation, and (3) to determine the extent of relationships amongst the villagers’ characteristics and their participations in forest conservation. The population of the study was the residents of nine near forest villages in Parung Panjang sub-district, District of Bogor. The sample was 115 residents taken randomly from the population in those villages. In conjunction with this, this study was designed as a descriptive-correlation research. The independent variables were the villagers’ characteristics and some supporting factors; whereas the dependent variable was the villagers’ participations in the forest conservation. Data were collected through interviews with the villagers in February through April 2006. Descriptive statistic procedure was used to analyze the obtained data. The research findings pointed out that: (1) most of respondents involved in the study were in the older age category, of the Sundanese ethnic, low in education, had never received any training in forest conservation, low in forest conservation knowledge, mostly worked as up-land farmers for five hours daily, and had also low income, (2) their participations in planning, implementing, and evaluating forest conservation as well as in using the forest products were low, and (3) the extents of relationship amongst their characteristics included some supporting factors and their participations in forest conservation were either low or negligible.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Electron microscopy has proved to be an invaluable discipline in studies on the relationship of viruses to the origin of leukemia, sarcoma, and other types of tumors in animals and man. The successful cell-free transmission of leukemia and sarcoma in mice, rats, hamsters, and cats, interpreted as due to a virus or viruses, was proved to be due to a virus on the basis of electron microscope studies. These studies demonstrated that all the types of neoplasia in animals of the species examined are produced by a virus of certain characteristic morphological properties similar, if not identical, in the mode of development in all types of neoplasia in animals, as shown in Fig. 1.
