Since Roll-Over Protective Structures (ROPS) are mandatory on tractors, the number of fatalities caused in the event of an upset is definitely reduced. Nevertheless, fatal accidents caused by machine loss of stability are still of great concern. In fact, despite ROPS have reduced injury to agricultural operators, tractor stability is still a complex issue due to its high versatility in use, especially considering normal operations in field, when interactions with the environment such as soil morphology and climatic conditions are involved, as well as interactions with operator skills and experience. With the aim of collecting data on different variables influencing the dynamics of tractors in field, a commercial device that allows the continuous monitoring of working conditions and the active configuration of the machines was fitted on standard tractors in normal operation at the experimental farm of the Bologna University. The device consists of accelerometers, gyroscope, GSM/GPRS, GPS for geo-referencing and a transceiver for the automatic recognition of tractor-connected equipment. A microprocessor processes data and provides information, through a dedicated algorithm requiring data on the geometry of the tested tractor, on the level of risk for the operator in terms of probable loss of stability and suggests corrective measures to reduce the potential instability of the tractor.

Regional Factors

In view of the significant increase in grain production in Russia, a methodological approach is proposed to analyze the significance of regional factors of grain crop yield growth in the country in recent years, especially against the background of the lack of expansion of acreage under grain crops. Based on the results of the calculations, the effectiveness of the influence of climatic, financial, infrastructural and production factors on the growth of grain yield was described. It is concluded that various factors had different effects on the growth of grain crop yields in regions with high-, medium - and low-intensity grain production complex. The role of reducing the influence of financial factors on the growth of grain yields and a sharp increase in the role of agro-climatic conditions is noted. The revealed trend of increasing depreciation of fixed assets of agriculture as a whole is particularly emphasized, with a slight increase in the volume of their renewal and modernization in the leading regions in terms of grain crop yield growth. Without taking appropriate measures to reduce the depreciation of fixed assets in the near future, this will result in a sharp decline in the achieved volumes of grain production in the country.

The North

Circumpolar territories and the regions related to the Arctic are those rich with natural resources. They have a high potential for the development of mining and extractive industries. The abundance with resources makes the North increasingly attractive for investments. However, circumpolar territories are characterized by peculiar socio-economic, natural, and climatic conditions which taken together frequently pose a negative impact on people and hinder the exploration opportunities of the Arctic resources. In global, regional, and sub-regional levels, the development of the Arctic is heavily regulated by multilateral international treaties. However, the issues of monitoring and assessment of the sustainable development of the Arctic remain open, which stems from the absence of agreed criteria and indicators for assessing sustainability in the context of national, regional, and scientific approaches. It necessitates the development of a specific methodological approach to the establishment of a system to monitor and assess the sustainable development of the Arctic.

ssible designing of reinforcement constructions. Yet some problems in simulation of landslide situation do occur. Options for using different soil models and calculation schemes are being analyzed on the example of protective structures construction for railway tunnel in the city of Sochi region. Simulation of landslide slope condition is carried out using geotechnical software Plaxis conside­ring different soil models (Linear Elastic и Mohr-Coulomb) and «reconstruction» of structures displacements. The value of retaining wall displacement alongside landslide slope as well as retaining walls sections inner movement is being estimated by results of complex monitoring. Recent developments were causing threat to the safety of building and construction works continuation at the railway and also to the normal operation of structures lower down the slope.

The Relationship

Fifty years down the line, the analysis of computer music is still a very complex issue, highly dependent on the identity of computer music itself: the variety of software, the lack of a common musical notation for scores, the absence or presence of computer data. This has led to the emergence of a multitude of analytical methods, including aesthesical analysis, which approaches music from the point of view of perception, and poietical analysis, which pays attention to the creative process.This study aims to combine these two methods of analysis in order to understand the relationship between technology and the actual piece of music. The article presents a methodological approach – focused on six pieces produced at IRCAM in Paris and at CSC in Padua, between 1975 and 1985 – via an in-depth consideration of Mauro Graziani's Winter leaves, a work conceived in 1980 at the CSC using Music360. The method used consists of comparing data collected using a diversity of practices: repeated listening, the tracing of graphical schematics, sonogram and spectrogram analysis, data listing analysis. An algorithm has also been created in order to calculate the degree to which the software is exploited and to enable a comparison between the different analyses. It is hoped that this procedure will combine traditional musicological methods with new approaches suited to the medium and grounded in a thorough knowledge of computer technology and musical environments.

The methodological approach was suggested to define a rational heat load of the air conditioning system (ACS) with taking into consideration the current climatic conditions of operation. The proposed approach is based on the hypothesis of sharing the current changeable heat load on the relatively stable share as the basic one for choosing installed (designed) refrigeration capacity of the refrigeration machine, operating with high energy efficiency in nominal or similar modes, and unstable heat load, corresponding to ambient air precooling at changeable current temperatures. To prove the methodological approach to defining a rational heat load of the ACS was carried out the analysis of current values of heat loads of the refrigeration machine ACS during cooling ambient air from its changeable current temperature to the temperature of 10, 15 and 20 ºС . It is shown that due to the different rates of annular refrigeration capacity production increment to cover the current heat loads with increasing the installed refrigeration capacity of the refrigeration machine, caused by the changes in heat load according to current climatic conditions during all the year round, it is necessary to choose a such heat load on the refrigeration machine of ACS (its installed refrigeration capacity), that provides a maximum or similar annular refrigeration capacity production at relatively high rates of its increment. Therein, the value of heat load for ambient air precooling is calculated according to remained principle as the difference between the rational total heat load and its basic relatively stable share. The proposed method is useful for defining a basic installed refrigeration capacity of the refrigeration machine of ACS with the accumulation of excessive (unapplied) refrigeration capacity at lowered current heat loads on ACS and its application for ambient air precooling, that is for covering unstable heat load share on ACS

The Impact

Situé dans une zone géographique où les ressources hydriques sont limitées, le Maroc a multiplié les efforts pour gérer ses ressources en eau. Ces efforts se sont concrétisés à travers l’amélioration continue du cadre législatif régissant le secteur de l’eau et s’adaptant aux nouvelles contraintes qu’elles soient climatiques, technologiques et/ou économiques. Dans ce sens, ce travail vise l’évaluation de l’impact de ces interventions publiques sur la croissance agricole et économique observées. La démarche méthodologique adoptée se base sur la méthode de comptabilité de croissance ou « Growth Accounting », développée par Solow en 1957. Elle permet de décomposer la croissance en contribution des facteurs et celle de la productivité. Les résultats de cette étude confirment le rôle primordial que joue l’agriculture en tant que moteur de croissance de l’économie marocaine. Ils montrent également que la contribution de l’eau à la croissance de la valeur ajoutée agricole est de l’ordre de 2% et qu’elle demeure tributaire des conditions climatiques, qui à leur tour changent sous l’effet du réchauffement climatique. Located in a geographical area with limited water resources, Morocco has multiplied its efforts to manage its water resources. These efforts have been materialized through the continuous improvement of the legislative framework governing the water sector and adapting to the new constraints whether they are climatic, technological and/or economic. In this sense, this work aims at evaluating the impact of these public interventions on the observed agricultural and economic growth. The methodological approach adopted is based on the growth accounting method developed by Solow in 1957. It allows for the decomposition of growth into factor contributions and productivity contributions. The results of this study confirm the primary role played by agriculture as an engine of growth in the Moroccan economy. They also show that the contribution of water to the growth of agricultural value added is around 2% and that it remains dependent on climatic conditions which are changing under global warming.

Abstract. In this paper, we present a methodological approach based on a comparative analysis of floods that occurred in a wide region over a long period and the climatic data characterising the same period, focusing on the climate trend. The method simplifies the comparative analysis of several time series by defining some indexes (e.g. the monthly, bi-monthly, and ... m-monthly indexes of precipitation, temperature, wet days and precipitation intensity and the monthly flood number) that can be used to study phenomena such as floods that are characterised by spatial and temporal variability. The analysis was used to investigate the potential effect of climate variation on the damaging floods trend. The approach was tested for the Calabria region (Italy) using historical flood and climatic data from 1880 to 2007. The results showed that the number of floods was correlated with the monthly indexes of precipitation, wet days, and daily precipitation intensity. The following trends were recognised: decreasing precipitation and wet days, almost constant precipitation intensity, increasing temperature, and linearly increasing floods. A second-order polynomial trend analysis showed a slight decrease in floods since the seventies, which might be explained by the favourable climatic conditions during the period and/or the effect of increasing awareness of flood vulnerability.

Target. To analyze the features of energy consumption of the building of the educational building No. 17 of the National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" in the conditions of quarantine restrictions in the implementation of energy-saving heating schemes.Methodology. Dynamic energetic modeling of a university academic building created in the DesignBuilder software environment under normal and quarantine modes.Results. Recommendations for the implementation of energy-saving modes of heating the building of the academic building of the university during the period of distance learning when introducing quarantine restrictions in Ukraine.Scientific novelty. An integrated approach has been developed to an in-depth analysis of energy consumption under conditions of partial use of the premises of educational buildings during the quarantine period. It is substantiated that the use of premises with partial operation of the building requires additional unit costs for heating needs.Practical significance. Simulation dynamic modeling of the building's energy consumption for heating for various modes of operation and employment / use of premises of educational buildings during the quarantine period in Ukraine, the results of the study will allow to obtain a set of energy characteristics of the building as a whole and its individual rooms / zones for hourly changes in internal operating conditions and external climatic conditions. The use of the proposed scheme of operation of the heating system of the building of the educational building allows to reduce energy consumption during the heating period by 8,5% compared to energy consumption during normal operation, which is economically feasible in conditions of partial occupancy of the building during quarantine restrictions (during lockdown) and an unpredictable macroeconomic situation on the energy market, causing a trend towards an increase in prices for basic energy resources.

AbstractLoess accumulation and paleosol formation are important Quaternary geoarchives in northern Iran. Two loess-paleosol sequences at Mobarakabad and Aghband were examined using soil morphology and micromorphology, mineralogy, magnetic susceptibility (MS), free Fe oxides and calcium carbonate equivalent. The loess-paleosol sequences provide a record of changes in paleo-rainfall in the northern Iran. Micromorphological and MS differences between the loess and paleosols in the sections reflect changes in climate. The different behaviors of magnetic susceptibility between Aghband and Mobar-akabad loess are mainly produced by their different pedogenic environments, topography and climatic conditions. As a result, the MS at the Mobarakabad section is much higher than at Aghband. Paleoeco-logical reconstructions coupled with magnetic depletion in paleosols at Mobarakabad suggest a wetter climate dominating during the formation of the paleosols.
