Intense and constant anthropic interventions transform extensive forest landscapes into mosaics of disturbed or degraded ecosystems. These ecosystems can restore themselves spontaneously, depending on the attributes offered by the physical environment and their capacity for resilience. This study’s objectives were the identification of plant formations in a conservation unit and the variables of the physical environment which favor the spontaneous restoration processes of the landscape. These variables were divided into classes using ArcGIS 10 and analyzed through the Principal Component Analysis. The concave curvature of the terrain was the physical factor which best contributed to the formation of a secondary forest in medium and advanced stages of succession, indicating that curvature is the determining factor for the spontaneous restoration of the landscape.

Exposome research is focused on all the exposures individuals experience during their lifetime and how it shapes their health and development of disease. The chemical and biological aspects of the exposome are readily available in data formats. In comparison there is a lack of data frameworks available for physical factors (e.g. noise, lighting, electromagnetic fields) and their biological relationships which would allow a greater understanding of the contribution of the physical environment on disease development and burden. We present the construction of a prototype that captures knowledge on physical factors and their interactions with genes and diseases derived from the biomedical literature to reflect the physical exposome.

Forest restoration is needed to improve the condition of degraded ecosystems and boost up the ecological services. The existence of forest areas, especially in Indonesia, cannot be separated from the livelihoods of the people living around them. The purpose of this study was to evaluate whether the feasabiluty of the community-based forest restoration programme, implemented by the Gunung Gede Pangrango National Park Agency (BBGGPNP) and its partners, is feasible and can support efforts to restore forest ecosystem functioning and build community independence in managing the forest ecosystem. This study used the Context, Input, Process and Product (CIPP) method. This is an evaluation model which provides an analytical and rational basis for programme decision-making, based on a cycle of planning, structuring, implementing and reviewing and revising decisions, examined through a different aspect of evaluation –context, input, process and product evaluation. Data were obtained from field observations, interviews and document analysis. Aspects of the programme ‘Context’ were found to be categorized as good and can become the basis for programme implementation, Programme ‘Inputs’ were also determined to be good, and fulfilled the criteria required to support the achievement of programme objectives. The ‘Process’ aspects were found to be sufficient, with key areas for improvement included the need for better coordination with partners and the need to respond to technical restoration requirements by adjusting the area of land to be restored, the number of trees to be planted, and by considering the technical rule of restoration. The ‘Product’ aspect of the programme were shown to be good, is shown by the achievement of the target amount and growth of trees and the increased capacity of human resources as well as the development of independent businesses in the ex-encroachers who were the programme participants. Based on these results, it can be concluded that the community-based forest restoration programme such as conducted by the GGPNP Agency is feasible and can be implemented in similar sites.Restorasi hutan diperlukan untuk memperbaiki fungsi ekosistem hutan yang terdegradasi.

The paper deals with urgent issues of development of resource-saving methods of biotechnological processes intensification. The main purpose of the work is to show the efficiency of using extremely low doses of physical factors impact in food biotechnology. Acoustic and electric treatment was in various modes. Impact capacity did not exceed 10-4 W/kg. The duration of exposure ranged from 5 to 15 min. Barley grains enzymes and lactic acid microorganisms were subjected to treatment. Impact of vibration as a physical factor, its frequency is considered as a priority in controlling growth and biochemical processes in biological objects. Impact frequency in the range of 50–10000 Hz influences the activity of hydrolytic enzymes in bimodal way. It is presented in the article. The coincidence of the frequency ranges of the maximum activity of enzymes in the model reactions with the ones in the grain of barley under the treatment of alternating current and sound is noted. Improvement of all indexes of germinating barley and improvement of the quality of the finished malt were observed in these ranges. Low-intensity acoustic treatment at a frequency of 2000 Hz contributed to an increase in β-galactosidase activity of the CT-95 Str. thermophilus strain. Selected ST-95 Str. thermophilus strain was used in the starter composition for the experimental sample production of fermented melted milk. The fermentation process intensification was observed. The lactose content of this product is 30% less in comparison with the feedstock. The use of traditional starter without a selected strain can reduce the lactose content by an average of 7.5%. The results of biotechnological processes modification by means of the treatment of enzymes and extremely low doses of physical factors impact used in meat technologies are observed. Thus, the prospects of using low-intensity physical effects of vibration in the development of innovative food technologies are substantiated. It is also promising to use these technologies in making absolutely new food products with different qualities.

This study aims to conduct the analysis of the physical fragility of the Municipal Natural Park Luis Roberto Correia Sampaio, correlating the different physical factors of the environment, analysing of the physical fragility of the environment supporting the environmental planning of this Conservation Unit. Checking through this correlation the consequences for the environment, determining the potential and emerging fragility of Park Municipal Natural Luis Roberto Correia Sampaio, Municipal Conservation Unit of Integral Protection, located in the municipality of Barbalha, CE. The choice of this Conservation Unit gave for its environmental importance, which in its natural features makes it unique. Therefore we adopted a methodology, which is based on cross-thematic maps of soil, slope and vegetation cover using geoprocessing tools. The tools used allowed the crossing of cartographic bases to the area classification by environmental fragility levels segregating the area in five levels of fragility, ranging from very weak to very strong. This type of study has practical application, since it provides a broad overview of the study area and serves as a tool for planning geared to sustainable development, and application of conservation practices.

The forest tent caterpillar, Malacosoma disstria Hbn., and the eastern and western tent caterpillars, M. americanum (Fab.) and M. pluviale (Dyar), are common pests of several species of deciduous trees in Canada. All are colonial during the larval stage, but M. disstria differs from the others in one respect: it does not construct a communal tent. This difference in habit merits special consideration in any comparative study of larval behaviour, particularly in one concerned with the effects of physical factors upon the insects, since a tent modifies the effects of the physical environment considerably. Recently, a series of such studies was carried out, and one part of the work consisted of laboratory and field observations on the light reactions of larvae. The results obtained have raised a number of new questions which unfortunately cannot be answered now, hecause two of the species have been difficult to obtain in quantity since 1950. Nevertheless, the findings are presented here without additional delay, since they are of general interest, and other workers may wish to use them.

MANETs is a network which has nodes. Communication is done without use of infrastructure. Quality based routing is developed which considers end to end qualitatiove data communication. A number of protocols were designed and suggested by researchers to achieve effective communication in MANETs. Considering number of quality factors as energy, trust, bandwidth etc a number of protocols are existing. But still there are number of factors those can consider to enhance the performance of the protocols used for the communication purpose. The existing schemes were effective enough but still as factors those were considering only the resources held by a node not the physical factors were present as node is to survive and communication in network. So further enhancements were possible by considering the physical parameters. Inspired from that in this paper a proposed scheme considering physical factor name as Distance is considered as the improvement to the traditional scheme. The distance factor is behaving as finding the physical presence of the node in the network also the distance factor will help to find the appropriate node for the next hop to communicate. A simulation is conducted in MATLAB software and performance factors as throughput and energy are analyzed, also an comparison with existing system is done and the results shows that the proposed scheme is effective enough to achieve QOS based routing with reduced energy consumption and high throughput.

Soil-vegetation interrelationships in a secondary forest of South-Southern Nigeria were studied using principal component analysis (PCA) and canonical correlation analysis (CCA). The grid system of vegetation sampling was employed to randomly collect vegetation and soil data from fifteen quadrats of 10 m × 10 m. PCA result showed that exchangeable sodium, organic matter, cation exchange capacity, exchangeable calcium, and sand content were the major soil properties sustaining the regenerative capacity and luxuriant characteristics of the secondary forest, while tree size and tree density constituted the main vegetation parameters protecting and enriching the soil for its continuous support to the vegetation after decades of anthropogenic disturbance (food crop cultivation and illegal logging activities) before its acquisition and subsequent preservation by the Cross River State government in 2003. In addition, canonical correlation analysis showed result similar to PCA, as it indicated a pattern of relationship between soil and vegetation. The only retained canonical variate revealed a positive interrelationship between organic matter and tree size as well as an inverse relationship between organic matter and tree density. These extracted soil and vegetation variables are indeed significantly important in explaining soil-vegetation interrelationships in the highly regenerative secondary forest.

Microlaena stipoides is widespread in the higher rainfall areas of Australia. It is consistently reported in the literature as providing high quality forage, yet anecdotal evidence suggests a wide range of opinions about the value of M. stipoides among graziers who manage areas with abundant M. stipoides. This paper addresses three questions relating to this divergence of opinion. Are landholders responding to inherent variability within M. stipoides? Is M. stipoides responding to different site and management conditions, prompting landholders to value it preferentially where site or management suit? Or are the landholders' judgments of M. stipoides influenced less by the actual performance of the grass on their properties than by social factors? Data collected from ten properties in the Victorian Upper Murray included a morphological assessment of M. stipoides samples, quantitative site and pasture information and qualitative data from interviews with property managers. Ecotypic variation and responses to site and management variables were found, but there were no apparent relationships between these parameters and the value judgments made by the landholders. The only physical factor which appeared to have any influence on landholder opinion was the annual rainfall for their property, although this was not through direct impact on other site attributes. It seems that social rather than physical factors may need to be explored in order to understand the factors influencing landholder opinion of M. stipoides.
