The evaluation of the embryonic root and stem of bread wheat (Triticum
aestivum L.) in the early stage of development (seedling stage) can be a
powerful tool in wheat breeding aimed at obtaining ...progenies with a greater
early vigour. It is revealed that genotypes with faster early vigour have
produced higher biomass and grain yield. In this study, the evaluation of
traits of the embryonic root and the embryonic stem of 101 bread wheat
genotypes was preformed at the 10-day old seedlings. The following eight
morphological traits of roots and stems were analysed: primary root length,
branching interval, the number of roots, total length of lateral roots,
angle of seminal roots, stem length, root dry weight and the stem dry
weight. Analysed lateral roots included seminal roots. The greatest, i.e.
the smallest variability of observed traits was detected in the branching
interval, i.e. the stem length, respectively. The highest positive
correlation was determined between the primary root length and the total
length of lateral roots. The cluster analysis, based on observed traits,
shows that genotypes were clearly divided into two main clusters, A and B.
The two clusters essentially differed from each other in the values of the
following traits: primary root length, total length of lateral roots, root
dry weight, stem dry weight and the stem length. Genotypes with shorter
primary and lateral roots, lower root and stem dry weight and a shorter stem
were grouped in the cluster B. On the other hand, the cluster A encompassed
genotypes with values of these traits above or around the average. The
values of the remaining analysed traits: the angle of seminal roots, the
number of lateral roots and the branching interval varied greatly between
obtained clusters. The cluster analysis showed the homogeneity of genotypes
originating from Serbia and the region; their values of the root and stem
length and weight were mostly around and below the average. However, the
values of the angle of seminal roots, number of lateral roots and the
branching interval were above average.
Environmental management accounting is a very important source of information for decision-making management of the company. In many companies there were created a detailed and dynamic system of ...recording and processing of data on environmental costs that companies mistakenly issued for environmental management accounting. And also today for environmental accounting in the CR it is characteristic that in organizations is not normal monitoring of the environmental costs considered as part of an integrated system for monitoring and evaluation of material, energy and financial flows. Companies do not use a wide range of options that the environmental management accounting provides. Why do not companies introduce environmental management accounting into its information system and do not use all the opportunities that EMA provides? In practice there are many barriers that prevent full-fledged process of implementation of environmental management accounting in the information system of companies. Many barriers were identified and were therefore subjected to cluster analysis. Clusters filled by identified barriers under the rules of cluster analysis are the result of cluster analysis.
Environmental Management Accounting (EMA) is a system, which collects, records, evaluates and disseminates information about environmentally induced financial impacts and environmental impacts of the ...system itself. EMA is an important source of information for decision-making processes such as management of an organization, for EMS or environmental reporting. Identified barriers were included in the study which was conducted in three phases – in organizations espousing to Responsible Care, in selected companies with ISO 14000 and in companies with environmental management systems, validated by European EMAS. In early 2010 research was completed in the field of environmental management accounting and barriers defending the implemention of EMA to organization’s information system and the subsequent use of EMA. Primary data obtained from this study were subjected to cluster analysis and the results are presented in this scientific thesis. In practise there are many obstacles to full-fledged EMA implementation process into practice organization and its functioning. Findings of the study give answers to the question: „What barriers act as obstacles to the implementation of EMA into the practise of the organization and its functioning?“
The experience gained in the use of visual and digital decoding methods of satellite imagery is considered (analysis of curves for spectral images, method of basic components) with the view of ...comparing their advantages for application in soil studies within the different natural zones of the country. Some methodical approaches are proposed to modify the decoding process for obtaining the more reliable information on the studied object
Under consideration is a regionalization version corrected with the aim to renew taxons, to give a new interpretation of farming systems and to specify the qualitative and quantitative ...characteristics of the soil cover in agricultural areas. It is of great interest from the historical viewpoint, permitting to study the stages in the development of the purposeful regionalization. The present data may be useful for elaborating new specialized regionalization using the modern GIS-technologies for forecasting the development of agriculture in the nearest future.
The methods of multidimensional statistics and claster analysis were used to create an automated classification and diagnostics of the pore space in 200 micromorphological vertically oriented thin ...sections prepared from podzolic soils (the Republic of Komi, Russia), soddy-podzolic soils in the Moscow region, gray forest soils (Tula region) and chernozems (Kursk and Voronezh regions in Russia, Odessa region in Ukraine). The computer imagination analysis permitted to study fine macro-voids ( d = 0.2-2 mm) in the field of vision 2x2 cm. Every void in the field of vision was measured to determine its section area ( S ), perimeter ( P ), diametrical ( D ) and longitudinal ( L ) sections, orientation of the long section axe in the plane thin section and the form factor F = (4 pS / P2 + D / L )/2. 100-150 voids were taken for measurements in every thin section. To characterize the pore space in thin sections, under use were also the empiric distribution of voids according to the form factor and orientation as well as the average length of voids in the field of vision. The discrimination analysis made it possible to elaborate an automated system and to give the morphometric characteristics of the pore space in the studied soils with varying structures so specific for loamy soils at the territory of European Russia including crumbly, granular, nutty, platy, massive-platy, fissure-like and massive structures. The results of the automated diagnostics have a rather high similarity with the expert visual assessment of the pore space in thin sections (75-90%).
The purpose of this study is to bear out the claim that the spread of ubiquitous society is improving our behaviors in architectural and urban space. Specifically, the current situation of working ...mobility over time and space is investigated through the log analysis of e-mail access by discretionary labor. For 81 workers of a certain organization, the each number of real and cyber workplaces is tallied from the 3,241,805 records of e-mail access log files from Sep 1, 2007 to Feb 29, 2008. The percentages of local and remote works are evaluated from the recorded IP addresses and protocol types (POP and IMAP). The percentages of working hour, overtime, and holiday works are also evaluated from time stamps of these records. Then, cluster analysis is performed on the 4 variables; number of workplaces, percentage of remote works, percentage of extra works, summation time of working. As the result, the workers of discretionary labor are categorized into the following 4 working styles; conservative type, temporally-modulated type, spatially-distributed type, and post sedentary type.
The Yatsushiro Sea in central Kyusyu, southwest Japan is representative enclosed sea in Japan. Recently, various environmental degradations are reported in Yatsushiro Sea, as red tide and anoxic ...water. In this study, we clarified distribution of sediments and benthos in Yatsushiro Sea by using claster analysys. As a result, pH and temperature showed a constant value. Total sulfide and mud component are strong value in Yatsushiro Sea inner part. In the benthos resalt, we suggested benthos is affected by nutrients and total sulfide.
