Definition Of

A scientific project focused on the development of a methodology for assessing energy efficiency classes of industrial facilities identified the primary research problems. The first and most important of them is the absence of a categorical and conceptual apparatus in the field of energy efficiency in industry, both in the Russian Federation and at the global level. This fact limits the definition of the system of indicators in the diagnosis of energy consumption. The study analyzed the definitions of an industrial facility contained in the current legislative and regulatory documents, as well as related assessment categories, such as: an industrial building and an industrial enterprise. The lack of unity in the definition of the identified categories, and in some cases their contradiction, demanded clarification of the category “industrial facility” as an object of diagnostics of energy consumption in industry, within the framework of an expert survey with the involvement of Russian and foreign experts in the field of energy. The practical significance of the results of the study is that the clarification of the category “industrial facility” is an integral attribute of the process of developing a methodological framework for assessing energy efficiency in industry, affecting its substantive part.

Basic principles for definition of a tolerable risk as a criterion for decision-making in risk management are considered. It has been shown that the principle of common sense (ALARP) allows define boundaries for justifiable costs of risk reduction. Examples for definition of tolerable risk to hazardous production facilities personnel, population, and environment are presented. It has been demonstrated that regardless of hazardous production facilities management for tolerable risk definition may be used risks of natural, man-made or other nature of the impact on people, property and environment. These risks may be evaluated either by objective statistics or by other methods. Tolerable risk level definition by stakeholders with participation of concerned parties, and not by formal approval this level by government agencies, makes the decision more effective.

Priority is given to ensure safety and efficiency of technological processes in hazardous industries, especially in mining operations. Such factories utilize enormous amount of safety sensors. Triggering any one of them stops operations both locally and globally. For example, a single belt conveyor is fitted with up to a hundred sensors and reaches few kilometers length. It is very important to quickly localize a position of a triggered safety sensor to proceed with elimination of an accident. The purpose of this work is to create a hardware-software monitoring system of extended objects (f.e. belt conveyor), which detects a triggering of a two-wire safety line. According to the purpose of this work the following were developed and tested: a physical control model that replicates the triggering of safety sensors, a hardware architecture of monitoring system, a mathematical model of separate nodes of devices, electrical schematics, and a device prototype. A function algorithms and software architectures for each device were developed and tested. As a result an experimental system prototype was developed with accordance to the rules of hazardous environment. On a basis of a monitoring system and a physical control model a simulation bench was developed. By results of concluded experiments following system specifications were deducted: safety sensor triggering detection in less than 100 ms, an address definition from 1 up to 3 simultaneously triggered safety sensors, definition of the type of accident. Created monitoring system may be used to control a variety of industrial extended objects, in particular in gas- and dust-hazardous environment, using discrete safety sensors.

Residential proximity to industrial facilities that release pollutants is a source of exposure to a high number of toxics, many of them known or suspected carcinogens. The objective of the study was to analyze the association between lung, larynx, bladder, and kidney cancer mortality and deprivation in areas proximate to polluting industrial facilities in Cadiz, a highly industrialized province in Spain. An ecological study at census tract level was carried out to estimate the mortality rates associated with deprivation and proximity to polluting industrial facilities (1–5 km) using the Besag–York–Mollié model. The results show a negative social gradient for lung and larynx cancers in males and greater risk of lung cancer was observed in the least deprived areas in females. These associations were found regardless the distance to industrial facilities. Increasing excess risk (relative risk; 95% credibility interval) of lung cancer for males (1.09; 1.02–1.16 at 5 km vs 1.24; 1.08–1.41 at 1 km) and bladder cancer for males (1.11; 1.01–1.22 at 5 km vs 1.32; 1.08–1.60 at 1 km) and females (1.32; 1.04–1.69 at 4 km vs 1.91; 1.28–2.86 at 1 km) was found as proximity to polluting industrial facilities increased. For kidney cancer, high risks were observed near such facilities for both sexes. Knowing the possible influence of industrial pollution and social inequalities over cancer risk allows the definition of policies aimed at reducing the risk.

Recent research in the area of computer-aided engineering design has focused on the development of environments that provide effective integration of several domain specialties for complex multidisciplinary synthesis problems. The definition of communication requirements for co-operative interaction—and the subsequent establishment of a conceptual model for automating the process—are important considerations in the development of such environments. A communication model can also provide the basis for development of a knowledge engineering strategy by defining the organizational and representational requirements for domain knowledge in the automated system. This paper presents a conceptual model for communication in automated interactive design and demonstrates how the model can be employed as a knowledge engineering tool to facilitate the acquisition and organization of domain expertise. Both the process architecture and semantic modeling aspects of the communication problem are considered. An example is included which illustrates the use of the model in formulating an automated integrated engineering system in the domain of floor and equipment layout and design for industrial facilities.

LABURPENA: Gaur egun jarduera industrialak behera egin du nabarmenki, eta horrek esan nahi du gero eta enpresa gehiagok jarduera utzi behar dutela. Ingurune fisikoari lotutako elementuak kutsatzen duten instalazioak eraikitzen badituzte, ingurumen-erantzukizuna xedatzen duten arauei men egin behar diete, kaltea eta kaltetutako ondasunak berrezartzeko neurriak har ditzaten. Lan honek zalantzak argitzea du xede zenbait gaitan, esaterako, kaltea zehaztu, kalte historikoen edo jarraituen eta operadorearen erantzukizunaren gainean. Halaber, baimenak eta Administrazioak duen esku hartzeko baliabideak aztertzen dira, ezagutzeko ea ezartzen dituzten tresnak ingurumen-erantzukizunari dagozkion arauak osatu, hobetu edo garatzen dituztenak. Azkenik, ingurumen-erantzukizunari araubide batua ematen dioten proposamenak azaltzen dira, behintzat teknikoki funtsezkoak diren kontuetan, adibidez, hartu beharreko neurriak eta diru kopurua zehaztea. RESUMEN: En la actualidad ha decrecido sensiblemente la actividad industrial y eso significa que cada vez más empresas deben cesar en su actividad. Si han llevado a cabo actividades que pueden contaminar elementos del medio físico, deberían someterse a las normas sobre responsabilidad medioambiental para determinar el daño y las medidas que han de adoptar para restaurar los bienes dañados. Este trabajo tiene por objeto solventar algunas dudas que presenta la normativa en materia de responsabilidad ambiental en ciertos aspectos, como la determinación del daño, los daños históricos o acumulativos y la responsabilidad del operador. Asimismo, se analizan los permisos y técnicas de intervención administrativa para conocer si establecen mecanismos que complementen, mejoren o desarrollen los remedios que ofrece la normativa sobre responsabilidad ambiental. Por último, se presentan unas propuestas que tienen por objeto dotar de un régimen unificado a la responsabilidad ambiental, al menos en aspectos técnicamente esenciales como las medidas a adoptar y su cuantificación. ABSTRACT: Currently industrial activity has decreased significantly and that means more and more individual companies need to close it down. In case they settle industrial facilities that can pollute elements of the environment, they should be subject to the rules on environmental liability in order to determine the liability and the measures they must take to restore the damaged goods. This work is aimed at solving some doubts raising the legislation about the environmental liability regarding some aspects, such as the definition of the damage, historical or sustained damages and operator´s accountability. Likewise, licences and permits are analyzed in order to know whether they set mechanisms complementing, improving or developing the regulation on environmental liability. Finally, some suggested improvements are proposed that are aimed at achieving a unified regime for the environmental liability, at least on technically essential issues, like the necessary measures and their economic value.

1. The definition of “normal” stars in spectral classification changes with time; at the time of the publication of theYerkes Spectral Atlasthe term “normal” was applied to stars whose spectra could be fitted smoothly into a two-dimensional array. Thus, at that time, weak-lined spectra (RR Lyrae and HD 140283) would have been considered peculiar. At the present time we would tend to classify such spectra as “normal”—in a more complicated classification scheme which would have a parameter varying with metallic-line intensity within a specific spectral subdivision.

Earth Dynamics

An ideal definition of a reference coordinate system should meet the following general requirements:1. It should be as conceptually simple as possible, so its philosophy is well understood by the users.2. It should imply as few physical assumptions as possible. Wherever they are necessary, such assumptions should be of a very general character and, in particular, they should not be dependent upon astronomical and geophysical detailed theories.3. It should suggest a materialization that is dynamically stable and is accessible to observations with the required accuracy.

Original Type

No paper of this nature should begin without a definition of symbiotic stars. It was Paul Merrill who, borrowing on his botanical background, coined the termsymbioticto describe apparently single stellar systems which combine the TiO absorption of M giants (temperature regime ≲ 3500 K) with He II emission (temperature regime ≳ 100,000 K). He and Milton Humason had in 1932 first drawn attention to three such stars: AX Per, CI Cyg and RW Hya. At the conclusion of the Mount Wilson Ha emission survey nearly a dozen had been identified, and Z And had become their type star. The numbers slowly grew, as much because the definition widened to include lower-excitation specimens as because new examples of the original type were found. In 1970 Wackerling listed 30; this was the last compendium of symbiotic stars published.
