A number of speculations are offered about the classification of building types and built forms, in the context of a project to build a database of the nondomestic building stock of England and Wales. This database will be used by the Department of the Environment to help assess national policy on greenhouse gas emissions and energy conservation. The speculations relate to the classification of building types by activities and forms; to criteria of room size and lighting for classifying built forms; to possible regularities in the relationships of wall area to floor area in forms so classified; and to the modelling of hybrid assemblies of different types of forms. Connections are drawn throughout to the land-use and built form studies pioneered by March and Martin at Cambridge in the 1970s, which have provided the starting point for many of the ideas put forward here.

Serbia’s Law on Planning and Building has imposed the topics of energy efficiency in building sector, requiring adequate policy making and providing a starting point for improvement of the current situation in this field. Considering the fact that there are more than 3.200.000 housing units without any statistical classification a need arose for establishing a national building typology as a starting point for further decision making and appropriate activities definition regarding the existing housing stock. After joining EU TABULA (Typology Approach for Building Stock Energy Assessment) project, methodologies and approaches of the European countries have been analysed providing a common experience, at the same illustrating a need for identification and classification of local characteristics. In order to obtain adequate data a comprehensive survey has been conducted, providing a starting point for creation of typology. The National Typology has identified typical “model” buildings and defined the levels of improvement ranging from standard (according to the current law) to the low-energy level. The paper explains the methodology, procedures and local characteristics of the process and gives an insight in the activity describing the problems and potentials of the approach.

Transport is a link between territories with different types of land use in urban areas. At the same time, the improved accessibility associated with the transport network can lead to increased segregation and a change in land use. The article analyzes the road network of the Najaf and Kufa cities, Najaf province, Iraq, in order to identify the spatial classification of roads and streets. Based on the analysis, three main types of roads and streets are identified with respect to their structural features and characteristics: regional, city and district. The dependence of the typology and location of transit-oriented zones on the classification of the road network is indicated. In the process of analyzing the study area, the most optimal points for the practice of transit-oriented development (TOD) are identified, the territories most favorable for the location of transit-oriented zones of regional, city and district significance are introduced, the main characteristics of these zones are given. In order to reach goals, this article includes the collection of data and the creation of a database for land use applying a geographic information systems (GIS) environment. The result of the spatial analysis are five regional nodes, six urban nodes and seven district nodes

This article has as a starting point the definition of the concept of ecological principles. Then, after classification of the principles of ecology (domestic principles and international principles), we present and critically analyze and compare the main principles in the field of ecology. Among the ecological principles on the domestic chain, we present and analyze 11 principles, namely: pollution must be combated at the source; the interests of environmental protection must be taken into account in all design or execution decisions; any exploitation or use of natural resources must be avoided if it is accompanied by damage; it is necessary to raise the level of scientific and technological knowledge, inter alia by supporting scientific research; the costs of preventing and combating pollution to be borne by the polluter; the activity of one state not to harm the environment of another state; during the elaboration of the community policy in the field of environmental protection to take into account the interests of the developing states; community environmental protection policy must be developed in the long term and protection must be comprehensive and international, which is achieved, inter alia, through cooperation within international bodies; the cause of environmental protection is everyone's responsibility and for this reason education is irreplaceable; depending on the source of pollution, the most appropriate level of action must be established taking into account the nature of the pollution, the necessary measures, the characteristics of the protected territory. This principle is defined as a "subsidiary principle"; it is necessary to harmonize and coordinate national policy in the field of environmental protection in accordance with the long-term commonly accepted directives. We also present and analyze the principle according to which environmental protection must be an essential element of the economic and social policy of the state. Finally, another ecological principle, the principle of prevention of ecological risks and damage

Newer integrated land use–transport models require as a base-year input a representation of existing built form (building stock by type, age, density, and other variables). Available data on floor space inventory have been found to be both incomplete and inconsistent with employment and population data in three land use–transport modeling exercises in the United States: in Sacramento, California; in the state of Oregon; and in Oahu, Hawaii. This paper reports on three methods used to synthesize a built-form input at a detailed microlevel for these three models. Each method uses existing land cover data and reconciles them with population data, employment data, and data on the consumption of floor space by activity. All three approaches assign floor space quantities by type to a detailed microlevel (grid cell or parcel) inventory of land. The approaches differ in their algorithmic approach, motivations, and data requirements.

Points Of View

Metallic clusters are interesting from various points of view, e.g. as a mean of spreading expensive catalysts on a support, or following heterogeneous and homogeneous catalytic events. It is also possible to study nucleation and growth mechanisms for crystals with the cluster as known starting point.Gold-clusters containing 55 atoms were manufactured by reducing (C6H5)3PAuCl with B2H6 in benzene. The chemical composition was found to be Au9.2[P(C6H5)3]2Cl. Molecular-weight determination by means of an ultracentrifuge gave the formula Au55[P(C6H5)3]Cl6 A model was proposed from Mössbauer spectra by Schmid et al. with cubic close-packing of the 55 gold atoms in a cubeoctahedron as shown in Fig 1. The cluster is almost completely isolated from the surroundings by the twelve triphenylphosphane groups situated in each corner, and the chlorine atoms on the centre of the 3x3 square surfaces. This gives four groups of gold atoms, depending on the different types of surrounding.

Increased Susceptibility

Keratitis and conjunctivitis (infections of the cornea or conjunctiva) are ocular infections caused by various bacteria, fungi, viruses or parasites; bacteria, however, are usually prominent. Systemic conditions such as alcoholism, diabetes, debilitating disease, AIDS and immunosuppressive therapy can lead to increased susceptibility but trauma and contact lens use are very important factors. Gram-negative bacteria are most frequently cultured in these situations and Pseudomonas aeruginosa is most usually isolated from culture-positive ulcers of patients using contact lenses. Smears for staining can be obtained with a special swab or spatula and Gram staining frequently guides choice of a therapeutic rinse prior to the report of the culture results upon which specific antibiotic therapy is based. In some cases staining of the direct smear may be diagnostic in situations where the culture will not grow. In these cases different types of stains occasionally assist in guiding therapy.

This paper reports on experiments designed to identify and implement mechanisms for enhancing the explanation capabilities of reasoning programs for medical consultation. The goals of an explanation system are discussed, as is the additional knowledge needed to meet these goals in a medical domain. We have focussed on the generation of explanations that are appropriate for different types of system users. This task requires a knowledge of what is complex and what is important; it is further strengthened by a classification of the associations or causal mechanisms inherent in the inference rules. A causal representation can also be used to aid in refining a comprehensive knowledge base so that the reasoning and explanations are more adequate. We describe a prototype system which reasons from causal inference rules and generates explanations that are appropriate for the user.

The article is devoted doctrinal issues of environmental and economic effectiveness of use land in conditions of infringement of institutional transformations. The modern approaches to the definition of content of ecological and economic effectiveness of land use are analyzed. It is established that the overwhelming majority of domestic researchers interpret this notion regarding the use of agricultural land or farm land. It is proved that such an approach is justified, taking into account the structure of the land fund of Ukraine. However, this reduces other goals of the land user and functions of the land. It is proposed to investigate the category of ecological and economic effectiveness of land use in accordance with the provisions of the ecological economics, social welfare theory, and concept of total economic value. Based on the classification of land functions, the criteria of selection material content and social form of ecological and economic effectiveness of land use are determined.

Chromatographic Parameters

Aim and Objective: In this study, chemometric methods as correlation analysis, cluster analysis (CA), principal component analysis (PCA), and factor analysis (FA) have been used to reduce the number of chromatographic parameters (logk/logkw) and various (e.g., 0D, 1D, 2D, 3D) structural descriptors for three different groups of drugs, such as 12 analgesic drugs, 11 cardiovascular drugs and 36 “other” compounds and especially to choose the most important data of them. Material and Methods: All chemometric analyses have been carried out, graphically presented and also discussed for each group of drugs. At first, compounds’ structural and chromatographic parameters were correlated. The best results of correlation analysis were as follows: correlation coefficients like R = 0.93, R = 0.88, R = 0.91 for cardiac medications, analgesic drugs, and 36 “other” compounds, respectively. Next, part of molecular and HPLC experimental data from each group of drugs were submitted to FA/PCA and CA techniques. Results: Almost all results obtained by FA or PCA, and total data variance, from all analyzed parameters (experimental and calculated) were explained by first two/three factors: 84.28%, 76.38 %, 69.71% for cardiovascular drugs, for analgesic drugs and for 36 “other” compounds, respectively. Compounds clustering by CA method had similar characteristic as those obtained by FA/PCA. In our paper, statistical classification of mentioned drugs performed has been widely characterized and discussed in case of their molecular structure and pharmacological activity. Conclusion: Proposed QSAR strategy of reduced number of parameters could be useful starting point for further statistical analysis as well as support for designing new drugs and predicting their possible activity.

Gathering Data

Chapter 4 provides an introduction to gathering data for scholarship of teaching and learning (SoTL) investigations, including the importance of triangulation, that is, collecting several different types of evidence. Examples are given of typical kinds of quantitative (numerical) and qualitative (non-numerical) data that might be used in a SoTL study. That quantitative and qualitative data are more closely related than it might seem at first is discussed. The taxonomy of SoTL questions—What works? What is? What could be?—provides a starting point for considering what type of data to collect. Suggestions are offered for ways to design assignments so that the coursework students produce can also serve as evidence, something that benefits both students and their instructor.
