DFT Analysis of Low-frequency Heme Vibrations in Soluble Guanylate Cyclase: Raman Mode Enhancement by Propionate–Protein Interactions
Authors: Kubo Minoru , Okuyama Orio , Kitagawa Teizo , Shigeta Yasuteru 
Published: August 2012

Abstract
Normal vibrational modes of heme have been analyzed using density functional theory, to assign a new Raman band observed at 312 cm−1 in the CO-bound, active form of soluble guanylate cyclase. The conserved YxSxR motif is incorporated into the model to reproduce the hydrogen-bonding network around propionates. A delocalized mode that involves Arg motions as well as pyrrole tilting and propionate bending is found to be the most likely candidate accounting for the new band.

Authors: Jin Xiongjie , Yamaguchi Kazuya , Mizuno Noritaka 
Published: August 2012

Abstract
An atom-efficient and green synthetic route to highly valuable imides (54–92% yields) from terminal alkynes and amides has been developed. This new route is composed of two consecutive reactions, that is, (i) the reported Cu(OH)2-catalyzed cross-coupling of terminal alkynes and amides to ynamides and (ii) the Sn–W mixed oxide-catalyzed regioselective hydration of ynamides.

Published: August 2012

Abstract
A novel pillaring procedure without alkylamine or tetraalkylammonium pretreatment has been developed to prepare SiO2/TiO2 pillared layered manganese oxide with large surface area. SiO2/TiO2 pillared layered manganese oxide is prepared by solvothermal treating H-type layered manganese oxide at 220 °C for 12 h in a mixed solution of absolute ethanol, tetraethylorthosilicate, and titanium isopropoxide. The obtained SiO2/TiO2 pillared layered manganese oxide is expected to be a selective catalyst or an improved battery material.

Published: August 2012

Abstract
Single-walled carbon nanotubes (SWNTs) with highly graphitized structure were synthesized by thermal chemical vapor deposition using an improved nitrogen-pretreated Fe–Mo/MgO catalyst. The effects of nitrogen pretreatment of Fe–Mo/MgO on the structure and properties of SWNTs were studied by TEM, Raman spectroscopy, and TGA. The investigations revealed that the nitrogen pretreatment of the catalyst promoted the growth of SWNTs. It also enhanced the structural features and thermal properties of SWNTs.
Consumer Mental Accounts and Implications to Selling Base Products and Add-ons
Authors: Erat Sanjiv , Bhaskaran Sreekumar R. 
Published: August 2012

Firms in a variety of industries offer add-on products to consumers who have previously purchased a base product. We posit that consumers, in making their decisions as to whether to purchase add-ons that complement the base products, find a greater need for the value offered by the add-ons when the “unrecovered” value (i.e., price paid minus the benefits obtained so far) associated with the base products is higher. We conduct experiments that test the proposed hypothesis and examine the strategic implications of such consumer decision making to a firm that sells base product add-on pairs. Consistent with our hypothesis, the experiments show that a consumer's unrecovered value associated with the base product is positively correlated to his likelihood of purchasing the add-on. Formal modeling of this bias shows that firms may find penetration pricing strategies (such as loss leader pricing) suboptimal. Furthermore, the identified bias leads the firm to spend more resources toward enhancing both the base product and the add-on quality, especially so when the add-on will be offered before the consumer has a chance to extensively use the base product. Finally, the effect of competition in the base product market is also considered.

Public Perceptions of Population Changes in Hungary
This study examines the public perceptions of population dynamics in Hungary. Based on a representative national sample survey from 2005, we discuss how the general public perceives demographic trends and attitudes people have towards the possible reasons behind these trends and solutions they believe are appropriate to contend with the trends. Rural populations were expected to have poorer knowledge of current population trends and changes and more conservative attitudes toward controversial demographic issues, but this expectation was not supported by the data. Since relatively little research has been conducted on population literacy, this study contributes to a better understanding of how public perceptions on population are formed and how this knowledge and attitudes may affect public policy addressing demographic trends.
Differences in Fertility Behaviour among the Farm, Rural and Urban Populations in Slovenia

Differences in Fertility Behaviour among the Farm, Rural and Urban Populations in Slovenia
Below replacement fertility in almost all European countries and lowest low fertility in a large part of the continent are significant demographic issues that concern contemporary policy makers and social scientists. Statistical data for Slovenia show that, with the exception of the farm population, all social groups have fertility levels that are below reproduction. This paper attempts to find out which factors are the most accountable for these differences and intends to contribute to broader scientific and public debates about the reasons for very low fertility in the ‘industrialized world’. The results of the analysis based on the survey "Generations and Gender Relationships on Slovenian Farms" (2007) indicate that differences in fertility behaviour among the farm and other parts of the Slovenian population are more related to the structural than cultural characteristics of the people.

Women's Contribution to Rural Development in Croatia: Roles, Participation and Obstacles
Unequal access to formal employment, decision-making power and social prestige can lead to vulnerabilities and social exclusion especially in rural areas. Feminist researchers and advocates for women assert that the preservation of agriculture, family farming and diverse rural culture in particular depend on the empowerment and participation of women (Hoff 1992, p. 79). In this paper, I attempt to evaluate rural/farm women's position and the extent of their vulnerability and social exclusion in an area of Slavonia in the eastern part of Croatia. Specifically, I use interview and fieldwork data to identify and elaborate their roles, participation in decision-making, and the obstacles/constraints that rural women face in these rural communities to evaluate the extent of their contribution to rural development. Further, it is my intention to explore if rural women represent an untapped resource in rural spaces that would contribute to rural development and raise the quality of life in these areas.

Sequential integration of measurements of navigational position parametersThe sequential method of integrating navigational parameters obtained from non-simultaneous navigational measurements is presented. The proposed algorithm of position coordinates estimation is general and includes two modes of data processing - from simultaneous and non-simultaneous measurements. It can be used in hybrid receivers of radionavigation systems integrating non-homogeneous position lines or in integrated navigation systems, particularly in receivers combining the measurements of various satellite navigation systems.
Conversion between Cartesian and geodetic coordinates on a rotational ellipsoid by solving a system of nonlinear equations

Conversion between Cartesian and geodetic coordinates on a rotational ellipsoid by solving a system of nonlinear equationsA new method to transform from Cartesian to geodetic coordinates is presented. It is based on the solution of a system of nonlinear equations with respect to the coordinates of the point projected onto the ellipsoid along the normal. Newton's method and a modification of Newton's method were applied to give third-order convergence. The method developed was compared to some well known iterative techniques. All methods were tested on three ellipsoidal height ranges: namely, (-10 - 10 km) (terrestrial), (20 - 1000 km), and (1000 - 36000 km) (satellite). One iteration of the presented method, implemented with the third-order convergence modified Newton's method, is necessary to obtain a satisfactory level of accuracy for the geodetic latitude (σφ < 0.0004") and height (σh< 10-6km, i.e. less than a millimetre) for all the heights tested. The method is slightly slower than the method of Fukushima (2006) and Fukushima's (1999) fast implementation of Bowring's (1976) method.
Any Lesson from the History of Sustainable Development?

Published: August 2012

Any Lesson from the History of Sustainable Development?Have we still got time for sustainability and reasonable application of ideas of sustainable development? It has been just over twenty years since the Brundtland Commission Report but, taken as an axiological term; sustainable development resonates with older historical horizons. At the heart of a long running history we are beginning to articulate more or less sustaining relationships between man and nature. We have described the (human) needs in the environmental, economic and social dimension of sustainable development to show some amazing shift in perception of sustainable development from local to global level. We are convinced that historical lesson of sustainable development shows there is no more time for sustainability, but time for SOStainability. Our proposed S-O-S in SOStainability means Save Our Sustainability! SOStainability represents the need to end the compromise between economic development and natural life supporting systems.

Analysis of Ecology of a Little Known White Oak Quercus Polycarpa Schur, Using Geobiocoenological Typology
Quercus polycarpa Schur is a little known oak species of the Sessile Oak aggregate (Quercus petraea s. lat.). Different habitats were studied using geobiocoenological typology system in order to investigate its ecology. In total, 65 experimental plots were set in forest stands with Q. polycarpa in the main storey in 12 protected areas situated in south-east of the Czech Republic. Ecological conditions, basic tree parameters and representation of Q. polycarpa within other oak species were evaluated on each plot. The mean values of height, height of life crown setting, stem and crown diameter were related to sub-categories of geobiocoenological system and compared by one-way ANOVA and Scheffé post-hoc test. It has been found out that Q. polycarpa grow in a high number in the 2nd altitudinal zone. It often occurs in a variety of habitats with different hydric and trophic conditions. As expected, the lowest values of measured parameters were found in the dry hydric range, this species reaches the highest values in the normal hydric and mesic ranges.

Transformation of the Slovak Cultural Landscape Since the 18th Cent. and its Recent Trends
The paper is focused on a long-term development of the selected Slovak cultural landscape types (plains, basins, uplands, highlands, and mountains) in approx. 200 years, which shaped the main land use features as well as on the recent transformation trends. The land use development analyses showed that from a long term view perspective several distinct periods can be distinguished. Each of these periods was characteristic for certain land use changes depending both on the landscape character or the socioeconomic situation. The recent trends as land use intensification (intense agriculture, sub-urbanisation, industrial construction) or land use extensification (agricultural land overgrowing) are considered to be common for the entire Slovak territory. Special transformation trends reflect more local conditions, human needs and preferences (construction of water reservoirs, wind calamities or tourism resorts) and though they are spatially isolated and small they influence the majority of Slovak inhabitants.
Topographic Exposure and its Practical Applications
Authors: Mikita Tomáš , Klimánek Martin 
Published: August 2012

Topographic Exposure and its Practical ApplicationsTopographic exposure is a topographic characteristic representing a degree of protection by a surrounding topography of a certain site. Detailed knowledge of topographic exposure has broad use in a number of applications ranging from studying forest wind damage through research on snow storage dynamics to optimisation in positioning wind power stations. This paper describes a method for creation of topographic exposure on the basis of a digital elevation model (DEM) using GIS. In combination with other climatic data on wind direction and speed, this factor is used to define the degree of terrain ventilation. Low terrain ventilation has, among other things, a significant influence on the creation of valley inversions and related vegetation zoning inversions. By combining the degree of terrain ventilation with DEM and forest vegetation zones in the area of the Training Forest Enterprise Křtiny, a clear relationship between the influence of topographic exposure, or terrain ventilation, and the creation of the vegetation zoning inversion was determined.
Integrative Research and Transdisciplinary Knowledge Production: A Review of Barriers and Bridges
Authors: Axelsson Robert 
Published: August 2012

Integrative Research and Transdisciplinary Knowledge Production: A Review of Barriers and BridgesContemporary policies about use of natural resources clearly pronounce sustainable development towards the goal sustainability as a focal objective. A key challenge for research is to support improvements and management by evaluation of sustainability policy implementation, i.e. outcomes on the ground and the social process in actual landscapes. However, while a landscape consists of integrated social and ecological subsystems and should thus be treated as a holistic unit or system, most research and postgraduate training is disciplinary. This means that very few researchers are equipped to solve problems or contribute to solutions in the non-academic world. There is thus a need for universities to learn integrative (interdisciplinary and transdisciplinary) research and knowledge production that meets complex challenges related to sustainable development and sustainability issues as for example management and governance of natural resources. In this paper I review the background, concepts and the barriers and bridges to integrative research and knowledge production. As a base for evaluation and development of integrative research projects I propose a normative model for integrative knowledge production processes. This was done through a literature review and a study of an integrative research project. I discuss how transdisciplinary research about landscapes and to solve complex sustainability issues can be designed, viz. (1) there is a need for a common understanding of different types of integrative research, (2) an outspoken aim to develop socially robust knowledge, (3) a model for transdisciplinary collaborative learning processes, and (4) a funding scheme that include academic and non-academic participants and matches the long process of partnership building during the full knowledge production process, from problem identification/definition to an improvement or a management solution.

Biosphere Reserves - Suggested Model of the Institution of Commons (Case study of the Šumava Biosphere Reserve)An attempt to address the interdependence between human economies and natural ecosystems has been articulated in ecological economics, among others, in terms of ecosystem services. Introducing ecosystem services yields positive result in the sense that the theoretical concept of cultural landscape has been complemented by the more or less effective political scheme, suitable as a basis for practical decision making. Nevertheless, practical management of ecosystem services on landscape scale is a rather complex task. The concept ofinstitution of commonscould be suggested to be used when dealing with the problem of implementation of ecosystem services concept in practice. The overall aim of the contribution is to discuss whether or not, or to which extent,UNESCO Biosphere Reserve, the modern strategy in biodiversity conservation backed up by internationally agreed upon conventions, can be used as a model for institution of commons in landscape-scale nature protection. The discussion is based on empirical evidence gained within a long-term research conducted in the Šumava Biosphere Reserve, Czech Republic.

Responses of Vegetation Stages with Woody Dominants to Stress and Disturbance During Succession on Abandoned Tailings in Cultural LandscapeStudies of ecological succession on tailing containments (abandoned sedimentation basins with waste deposited by a factory producing sulphuric acid from pyrite ore) near the village of Chvaletice (Eastern Bohemia, Czech Republic) were carried out since 1973 with increased intensity and complexity between 1986 and 2002 (Kovář 2004). Vegetation cover in its relationships to various factors has been periodically monitored up to now. The abandoned ore-washery deposit is characterized by relative strong toxicity of the sediment material (high heavy metal content) and fluctuations of the microsite conditions up to extreme values (pH, salinity, surface temperatures). Species richness and the courses of some ecological processes are influenced both by availability of plant diaspores (regional species pool) determined with the presence of adequate dispersal mechanisms (anemochory, zoochory) and by the seasonal moderation of environmental variables excluding stress non-tolerant species at extreme epizodes and enabling survival of resistant species during the competition. Long lasting existence of patches without any vegetation together with herbaceous types of stands and woody successional stages create mosaics on the surface plateau. The oldest tree stands (in average 20 - 30 years old) are predominantly formed byPopulus tremulaandBetula pendula, with minor admixture ofSalixsp. div. (mainlyS. caprea),Pinus sylvestris,Quercus roburorCerassus avium, rarelySarothamnus scoparius.The abundance ratio of two main dominants, aspen and birch, was changed for the benefit of the first one after the summer fire in extremely hot days. The effect of clonality on aspen regeneration and regrowth immediately after the fire disturbance was profitably manifested and it apparently facilitates the present state with aspen prevailing in the most forested tailing places at present, seventeen years after the fire. This fact supports the importance of clonal plant species role during primary succession.
Safety and Feasibility of an Exercise Prescription Approach to Rehabilitation Across the Continuum of Care for Survivors of Critical Illness
Authors: Berney Sue , Haines Kimberley , Skinner Elizabeth H. , Denehy Linda 
Published: August 2012

Background
Survivors of critical illness can experience long-standing functional limitations that negatively affect their health-related quality of life. To date, no model of rehabilitation has demonstrated sustained improvements in physical function for survivors of critical illness beyond hospital discharge.

Objective
The aims of this study were: (1) to describe a model of rehabilitation for survivors of critical illness, (2) to compare the model to local standard care, and (3) to report the safety and feasibility of the program.

Design
This was a cohort study.

Methods
As part of a larger randomized controlled trial, 74 participants were randomly assigned, 5 days following admission to the intensive care unit (ICU), to a protocolized rehabilitation program that commenced in the ICU and continued on the acute care ward and for a further 8 weeks following hospital discharge as an outpatient program. Exercise training was prescribed based on quantitative outcome measures to achieve a physiological training response.

Results
During acute hospitalization, 60% of exercise sessions were able to be delivered. The most frequently occurring barriers to exercise were patient safety and patient refusal due to fatigue. Point prevalence data showed patients were mobilized more often and for longer periods compared with standard care. Outpatient classes were poorly attended, with only 41% of the patients completing more than 70% of outpatient classes. No adverse events occurred.

Limitations
Limitations included patient heterogeneity and delayed commencement of exercise in the ICU due to issues of consent and recruitment.

Conclusions
Exercise training that commences in the ICU and continues through to an outpatient program is safe and feasible for survivors of critical illness. Models of care that maximize patient participation across the continuum of care warrant further investigation.
