Abstract:

The authors analyze the differences between the behavior of private firms and that of producer cooperatives in a matched sample of the two organizational types from the regions of Emilia Romagna and Toscana in North-Central Italy, where producer cooperatives are numerous. Individual firm-level surveys provide new detailed comparative data on key issues such as investment, productivity, wages, employment, and industrial relations. Differences between the two types of firm are found in labor relations, employment, pay, production methods, the relationship to the external market environment, and the level of economic performance. The authors find no significant differences in investment horizons or criteria for finance, despite theoretical assertions to the contrary. The cooperatives apparently have higher productivity, more labor-intensive production methods, lower income differentials, and a more tranquil industrial relations environment than the private firms.

Abstract:

- This paper presents a new approach that measures and analyses the economic growth of regions in relation to a macro-system. The primary findings are that southern and central regions of Italy have different spatial patterns and magnitudes of relative economic growth in comparison with the North of Italy. More specifically, the morphology of the growth shows that several regions have a negative disproportionate economic growth (allometry) when compared to the North of Italy. These are important results for policy makers, who should balance these regional inequalities. In particular, economic and industrial policies should boost regional economic development through an increase in regional productivity, which is positively affected by R&D activities, human capital and infrastructures of neighbouring regions.Keywords: Regional economic growth, regional inequalities, italian regions.JEL classification: O10, O47, R11

Abstract:

Purpose This paper aims to know the dimension and scope that research on the district effect has had in the literature about industrial districts, as well as to shed some light on the connection between industrial districts and business results; or expressed differently, on how being located in an industrial district or not affects or might influence the performance of the firms located therein. Design/methodology/approach The purpose of this paper has been achieved through an exhaustive review of the empirical literature dedicated to the so-called district effect. The papers selected in the analysis were selected on the basis of the following criteria: (1) publications in scientific journals; (2) studies carried out in Spain and Italy; and (3) works published between 1994 and 2017. Findings The outcome of the literature review suggests, on the one hand, that the debate on the extent to which the territory influences the competitiveness of firms located in industrial districts still remains a topic of great interest. It can additionally be observed that most of the works dedicated to measuring the district effect have done so using three dimensions: (1) productivity/efficiency; (2) international competitiveness; and (3) innovation. Practical implications From a theoretical perspective, the findings of this paper make it possible to carry out an integrating proposal for the measurement of the district effect which revolves around three dimensions (productivity/efficiency; international competitiveness; and innovation). Originality/value This paper makes a twofold contribution to the literature: (i) it brings together the most important empirical contributions that measure the competitive advantages obtained by firms located in industrial districts through the district effect; and (ii) it theoretically and empirically establishes the essential dimensions of that effect.

Abstract:

Purpose The purpose of this paper is to investigate the relational dynamics for innovation and, in particular, the impact of the openness of innovation process on the innovation capacity of organisations in restricted geographical contexts. Design/methodology/approach Through a negative binomial regression, the work analyses how the characteristics of the openness of the organisation’s innovation process in the period 2004-2010 influence the firm’s patent productivity in the following period (2011-2016). Findings The breadth of the open innovation (OI) process, here measured by the number of external network ties that an organisation realises for the realisation of its patents, has a positive effect on patent productivity. The depth of the openness, that is, the intensity of external network ties, has an equally positive influence on the innovative performance. However, after a tipping point, the patent productivity tends to decrease, underlining the costs and problems of OI practices. Research limitations/implications This study considers only patent collaborations in the city of Florence. Therefore, it focusses on codified innovations and on a single territorial case study. Practical implications The results underline the importance of the adoption of OI practices in restricted geographical contexts (such as cities, clusters or industrial districts) but with several limitations. Only collaborating more with others does not foster the organisation’s invention productivity, but different types of evidence are found here. Originality/value An original database has been created, containing all the information on patents realised in the area of Florence from 2004 until 2016, and a social networks analysis was applied to identify the local innovation networks.

Abstract:

The recent labor reforms implemented in Italy by the so-called "technocratic" Monti Government have challenged the traditional role of trade unions. On one side, the reforms in the pension and labor market have been approved without real consultation or bargaining with social parties, under the pressures from the financial and economic crisis and the austerity demanded by the EU central authorities. On the other side, the Government is urging trade unions to contribute to stimulating labor productivity in order to produce more growth and escape from such a long period of recession. The main aim of this article is to analyze the changing role of trade unions and then the real opportunities to open a new phase of social concertation, also taking into account the historical background of Italian industrial relations.

Abstract:

This pioneering work provides a systemic and comparative analysis of on-the-job training and research in Italy. This is done through an examination of industrial PhDs and apprenticeships for research purposes, which also takes account of the complex relations between businesses, tertiary education, and the labour market. To this end, the paper discusses the relationship between universities and employers, which is usually investigated through a perspective that only considers PhDs’ employability. Although a long-established research strand at both national and supranational level, the author tries to move away from this approach, questioning the effects that these new arrangements might have on productivity and the employers’ innovation capability in Italy. Cooperative research, and industrial and professional doctorates have been extensively covered in international literature. On the contrary, little interest has been shown towards industrial PhDs in Italy, even following the enforcement of Art. 11, par. 2 of Ministerial Decree No. 45 of 8 February 2013. A year since the Decree’s entry into force has elapsed, yet uncertainty still lingers over how to implement these innovative doctoral programmes. Consequently, this analysis sets out to be a first attempt at analyzing industrial PhDs, drawing on a comparison with those countries where they have been in place for a long time. The paper identifies a number of obstacles which act as stumbling blocks to the implementation of on-the -job training in higher education: the absence of placement services in the planning of training schemes and little commitment on the part of industrial relations actors. These shortcomings are the same which hamper the diffusion of apprenticeship schemes –including those for research purposes– which are decisive to fill the void between education and the labour market.

Abstract:

Identifying new tomato (Solanum lycopersicum L.) genotypes with improved technological performances is an important requisite for achieving high yield and quality of industrial produce. An open-field experiment was carried out in southern Italy in order to assess the effects of three elongated tomato hybrids oriented to ‘peeled’ chain (Max 14802, Massaro, Taylor) in terms of crop productivity and nutritional value. The hybrid Taylor showed the highest marketable yield due to the highest fruit number, whereas Massaro showed the highest processing efficiency. Among the three genotypes compared, titratable acidity and fiber were highest in Max 14802 fruits (0.45 g anhydrous citric acid·100 g-1 and 0.94 g·100 g-1 respectively), Taylor was best ranking in terms of fat and sucrose content, and Massaro achieved the highest glucose, fructose and rutin accumulation. Compared to fresh fruits, peeled tomatoes attained higher values of total and soluble solids, reducing sugars, total polyphenols (referred to fresh weight), rutin and naringenin, but had a decreased value of colour coordinate a/b ratio. No significant differences between the three tomato cultivars were recorded in terms of sensorial traits. From the present research interesting clues have arisen regarding the best performances of the hybrid Taylor in terms of fruit yield and organic acid content, and of the hybrid Massaro regarding the processing efficiency and fruit health-beneficial properties.

Abstract:

This paper analyzes robotized manipulation in the production of TV screens in a Videocolor plant in Anagni. A general procedure for manipulation analysis, based on the elementary actions concept, was applied to the study of robotized workcell performance and parameters. Manipulation analysis is presented as a practical application to stress its feasibility for practicing engineers. Kinescope manipulation by an industrial robot in a robotized workcell was analyzed and critical movement recognized and numerically evaluated. We also focused on performance and design parameters of workcell operation to significantly improve productivity through adjustments in robot and workcell programming and by slightly redesigning the workcell. This work was done under a research contract supported by Videocolor Ltd., Anagni, Italy, and results implemented in a new robotized workcell.

Abstract:

Purpose – The purpose of the paper is to highlight the considerations and lessons learned from a re-layout project in an assembly area for productivity improvement. The case study took place in Bosch Rexroth Oil Control Nonantola (Italy) with satisfactory results. The paper suggests how to approach reorganization projects with focus on productivity improvements following defined targets. Design/methodology/approach – After an analysis of the initial status, the authors examine several plausible layout alternatives: the main comparison criteria and their weights are defined. Then a scoring/measuring procedure follows for the criteria of each alternative, and the alternatives are compared using principal parameters analysis (PPA). Findings – The paper lists common considerations and lessons learned in the re-layout process. Using the PPA, the authors validate the best solution for the company. Originality/value – This paper shares a valuable experience that is general enough to be shared with many other assembly systems. A unique experience combining re-layout planning, MTM and use of PPA is shared with the readers.

Abstract:

Eucalyptus spp. has received attention from the research and industrial field as a biomass crop because of its fast growth and high productivity. The features of this species match with the increasing demand for wood for energy production. Commonly, the wood used for energy production is converted in chips, a material susceptible to microbial degradation and energy losses if not properly stored before conversion. This study aims at investigating two outdoor storage systems of Eucalyptus wood chips (covered vs. uncovered), assessing the variation in moisture content, dry matter losses and fuel characteristics. The class size of the material was P16, which was obtained using a commercial chipper appositely searched to conduct the study. The results highlighted how the different storage methods were influenced by the climatic condition: the woody biomass covered showed the best performances in terms of dry matter losses achieving 2.7% losses vs. the 8.5% of the uncovered systems. However, fuel characteristics displayed minor changes that affected the final energy balance (∆En = −0.2% in covered; ∆En = −6.17% in uncovered). Particle size varied in both methods with respect to the start conditions, but the variation was not enough to determine a class change, which remained P16 even after storage.

Abstract:

This article analyses the rules on wage coordination and their effectiveness in the Italian two-tier bargaining system. It seeks to cast light on bargaining coordination by starting from the analysis of collective agreements, rather than focusing exclusively on normative and institutional aspects of wage bargaining. Accordingly, the study examines a dataset of 498 company-level collective agreements concluded between 2012–2015 in three sectors – metalworking, food, banking and finance – to analyse wage developments in company-level bargaining. The study considers the extent to which local wage negotiations are consistent with the rules on wage bargaining coordination laid down in economy-wide agreements and national collective labour agreements. Wage coordination rules are generally respected, though a significant number of company-level agreements still provide fixed-rate pay rises in breach of the rule that wage increases at company level should be linked to productivity and other factors relating to the workers’ and/or the firm’s economic performance. Although the violation of wage bargaining rules between national agreements and company-level collective agreements is in line with the favourability principle, it is argued that local negotiations on fixed-rate pay rises could be regarded as a form of uncoordinated decentralization, diminishing the effectiveness of horizontal coordination policies and the normative role of the social partners.

Abstract:

The author examines the process of the labour market reform in Italy. The main provisions of the subsequent waves of reform are highlighted, with special emphasis on the reform of dismissal regulations, the role of the standard employment contract in response to labour market dualism, the measures aimed at enhancing functional flexibility and productivity, the growing importance of decentralized collective bargaining and the persistent shortcomings of security measures. The intrinsic limits of these reforms, deriving from their mainly neoliberal inspiration, are then examined. At the same time, it is argued that they have offered a chance for modernization of the labour law approach, which needs to be further developed in a constructive perspective going beyond a mere reaction to neoliberal challenges.

Abstract:

- Effectiveness, efficiency and affordability have been among the key criteria for municipal solid waste management in the Italian legal framework since the so-called "Ronchi Decree" of 1997. The paper analyses the economic performance of waste-collection firms in Italy. We construct a dataset that includes almost all the companies performing waste collection in the provincial capitals of Italy. We investigate their capital structure, profitability, value added, productivity, investment and business development by means of a set of financial ratios. The research is developed through the assessment of the effects on firms' performance of specialisation, localisation, temporal evolution, size and legal form of firms and the remuneration system for waste collection. The aim of this paper is twofold. First, given the almost universal nature of the sample under investigation, we describe the economic and financial structure of waste collection firms in Italy; second, we empirically evaluate the extent to which the sector has taken on the industrial characteristics set forward in the legal framework. Hence the analysis is conducted both at sector level and at firm level. At the aggregate level, it is possible to identify a trend for the sector as a whole towards convergence with the rest of the economy. However, waste management still displays clear signs of backwardness, especially due to weaker financial structure, higher incidence of labour costs on value added and lower investment. Firm-level data are analysed with both univariate and multivariate statistical techniques. The results confirm the general backwardness of the sector, with businesses located in Southern part of Italy lagging even further behind. Moreover, firms simultaneously providing multiple utility services are more profitable than those specialized in the waste sector only. However this appears attributable to cross-subsidisation between services, not economies of scope. Both scale of operations and legal form have a positive impact on firms' profitability, thanks in part to a negative correlation with degree of specialisation. Moreover, the economic performance of waste management firms is significantly pro-cyclical. Finally, the new cost-based remuneration system for collection services produces ambiguous results. It has a positive effect on operational efficiency and productivity but does not increase the return on capital. A simple econometric model is estimated to evaluate the simultaneous impact on firms' performance of specialisation, localisation, temporal evolution, size, legal form and remuneration system, confirming the outcome of the univariate analysis. In the light of our results, the successful "industrialization" of the waste management sector appears still far away.Keywords: local public services, waste management, regulationJEL classifications: L32, L51, Q53Parole chiave: servizi pubblici locali, gestione dei rifiuti urbani, regolamentazione

Abstract:

The aim of the research was to present the state of the art on the use of open and crowd-based platforms and the advantages in terms of business performance that emerging practices employing such technologies are able to provide. The analysis was performed by extracting information on emerging practices from the repository Business Process Framework for Emerging Technologies developed by the Department of Industrial Engineering of the University of Salerno (Italy). Contingency tables allowed analysis of the association of such practices with industry, business function, business process, and impact on performance. From the analysis of the results, many implementation opportunities emerge, mainly in manufacturing, healthcare, and transportation industries, providing benefits not only in terms of efficiency and productivity, cost reduction, and information management but also in product/service differentiation. Therefore, the research provides an overview of opportunities for organizations employing open and crowd-based platforms in order to improve market and organizational performance. Moreover, the article highlights in what specific business contexts these technologies can be mainly useful.

Abstract:

This article contributes to the political economic literature regarding the effects of industrial relations institutions on national economic outcomes. Based on an econometric analysis of the determinants of wage moderation in sixteen industrialized countries between 1974 and 2000, it argues that the organizational characteristics of trade unions have a significant impact on wage dynamics. Controlling for a number of institutional and economic factors, the countries in which trade union confederations directly involve workers in the process of collective bargaining ratification have on average lower wage growth relative to productivity than others. The authors also find that collective bargaining coordination and contract ratification magnify each other's wage-dampening effect. Through case studies of Ireland and Italy, the article examines the causal mechanisms underlying the uncovered statistical regularities and concludes that, particularly at a time in which classic political exchange is waning, worker involvement in contract ratification allows confederation leaders to resolve conflicting claims inside their organizations at lower wage levels than are achieved by a less participatory governance process.

Abstract:

Cotton is one of the most important industrial crops in the world. Though widely cultivated in Sicily (Italy) in the past, cotton growth on the island has disappeared today due to a complex variety of agronomic, economic and socio-political reasons. In recent years, increased interest in natural fibers worldwide has led to a revival in cotton plants in the Mediterranean area. The aim of this paper was to assess the response of Gossypium hirsutum L. cultivars to different environments and sowing times. Elsa and Juncal were selected from the most promising cotton cultivars regarding earliness and productivity. Plants were tested with three sowing times and in two Sicilian environments. Cotton yield and yield components were significantly affected by experimental station, sowing time and cultivar. Lint yield of cultivars was 1.60 t ha−1 on average, and the highest value of 1.99 t ha−1 was obtained from an early sowing time. The three indices of agronomic earliness varied significantly based on treatments. In conclusion, the evaluation of response genotype-by-environment under different sowing times could represent a strategy to obtain optimal cotton seed and lint yields, although other general aspects, such as labor costs, land availability and capital resources, should be also considered when evaluating the reintroduction of the species in Sicily.

Abstract:

Demand for automated processes in the manufacturing industry is now shifting toward flexible, human-centered systems that combine productivity and high product quality, thus combining the advantages of automated and robotic systems with the high-value-added skills of operators and craftsmen. This trend is even more crucial for small and medium-sized enterprises operating in the “Made in Italy” fashion industry. The paper presents the study, simulation, and preliminary testing of a collaborative robotic system for shoe polishing that can reduce manual labor by limiting it to the finishing stage of the process, where the aesthetic result is fully achieved, with a benefit also in terms of ergonomics for the operator. The influence of process parameters and design solutions are discussed by presenting preliminary test results and providing hints for future developments.

Abstract:

Plant growing substrates obtained by composting agro-industrial waste can serve as organic soil amendments. However, it is crucial to determine the maturity and quality of organic amendments before their application to soil. This study aimed to evaluate the suitability of compost obtained from poultry wastes combined with five different vegetal residues (tree trimmings, sugarcane bagasse, sawdust, cotton residues, and Napier grass) as growth media for container-grown Giant of Italy parsley. Fourier-transform infrared and laser-induced fluorescence spectra were used to characterize the humification extent in composts before and after the addition of charcoal at five inclusion rates (0%, 15%, 30%, 45%, and 60%, weight basis). Spectroscopic measurements identified absorption bands between 1625 and 1448 cm−1 specific to each of the 25 organic amendments evaluated. The most suitable amendments (composts made from sawdust and sugarcane bagasse) were associated with O–H stretching of phenols and aromatic rings. Charcoal addition to composts changed some of their physical characteristics, leading to increased nutrient availability in some cases. Experimental and calculated dry matter yield were compared via multiple linear regression and simple non-linear regression as a function of the spectroscopic and physicochemical (N, P, K, pH, EC, C, HLIF, C:N, CEC, HA:HA) properties of the organic amendments. Regression models accurately assigned high yields to the sawdust- and bagasse-based composts and low yields to the Napier grass- and cotton-based composts. Electrical conductivity (EC) was the main factor limiting potted-parsley productivity, an indication that efficient management of charcoal rate and compost EC levels can aid in predicting parsley yield.

Abstract:

Este trabajo se propone analizar el desempeño de la economía argentina desde mediados del siglo XX, recurriendo al análisis de la distribución funcional del ingreso y sus componentes –salario real y la productividad–, tanto para la economía agregada como para el sector industrial. A partir de la comparación con un conjunto de países desarrollados (Estados Unidos, Francia, Italia, Japón y España), encontramos que dichas variables presentan desde mediados de la década del setenta una evolución particularmente llamativa: la productividad crece a un ritmo inferior –incluso con momentos de caída o estancamiento– y el salario real retrocede marcadamente. En este marco, discutimos la explicación según la cual el empobrecimiento de los trabajadores argentinos es el resultado del proceso de desindustrialización sufrido –aunque sus indicadores se verifican con similar intensidad en aquellos países–, cambiando el eje hacia el débil desempeño de la productividad -y la consecuente ampliación de su brecha relativa–, que implica mayores costos para las empresas, que deben ser compensados con fuentes extraordinarias de ganancia. Una de ellas es, claro está, el salario real, de modo que el empobrecimiento de los trabajadores en Argentina resulta una pieza necesaria en el marco de la forma que adopta el proceso económico. This paper analyses the performance of the Argentine economy since the 1950s, through the analysis of the functional distribution of income and its components –real wage and productivity– for the economy and especially the manufacturing sector. Through comparisons with a group of developed countries (France, Italy, Japan and Spain, USA), we find that those variables have a striking evolution: the productivity grows at an inferior rate –including periods of stagnation– and the real wage falls dramatically. We then challenge the existing explanation of the impoverishment of the Argentine working class: the decline of our manufacturing sector. Since Argentinean indicators are no different than those of other countries, we emphasize the weak performance of the productivity –and the growth of the relative gap- that means higher costs for the firms, that must be compensated with extraordinary sources of profit. One of them is the real wage, and therefore the impoverishment of Argentine workers is a necessary piece of the economic process.

Abstract:

Maize silage is one of the most used feedstock for the anaerobic digestion plants in Italy. As biomass, it is necessary to choose maize hybrids and sowing times to reach the maturity stage at the planned harvest period. In addition, the contractor has to set up transport chains considering distances and other factors affecting the forward speed in function of the supplied biogas plants. This work examined different road conditions (length, weather and congestion) that might influence the maize silage transportation under both the energy and economic points of view. Tests were carried out with an agricultural tractor equipped with two trailers (a turntable steering and a dumper) along six itineraries (6.2, 15.3, 22.1, 32.5, 44.4, and 58.2 km) in two different traffic conditions: high congestion (early morning) and low congestion (evening). Tests were also performed in two seasons with different weather conditions: late Summer and early Autumn. The average forward speed was 27.40 km h–1 with a 15% difference between the best (evening and late Summer) and the worst (early morning and early Autumn) condition, with a productivity that varied between 9.50 and 81.98 m3h–1 respectively. The performed tests confirmed that the energetic evaluation is always positive also in the longest itinerary (58.2 km), but the actual market value of maize silage (52.00 € t–1) limits the convenience of the transportation distance up to 18 km. In conclusion, the study showed that the maize silage transportation using agricultural tractors not only depends on the travelled distance, but also on the road congestion and the weather conditions.

Abstract:

The economic crisis in Italy, as in Europe, affects heavily private companies and Public Administrations. In a few cases, however, organizations displayed an admirable capability of coping, due to innovation in design and management. An Italian Way of Doing industry is emerging. The paper advocates a new stream of policy oriented researches about cases and new paradigms Italian production system and Public Administration made in cooperation among institutions, universities, companies, associations: the basis for a new industrial policy. Collaborative projects of innovation and change management in specific companies and administrations should be fostered and supported, by developing best cases, new paradigms and communities of innovators. Innovation and changes in the organization may have a relevant impact upon macro dimensions of economy. Our society of organizations requires to all of them an improved capacity for coping dramatic changes. On the other hand, new forms of organizations may have a decisive impact on productivity and regulation. New products and services, new processes and a new model of consumption are part of a destructive creation that should be managed. The proposal is to cope the crisis by raising a strong scientific, cultural, professional movement oriented to invent a regenerate organization in private and public sector. Criteria drawn by our recent research are suggested. An agenda includes research and actions and the following areas of design and development: networks of territories and enterprises opened to the international market; integral enterprises as a basis of the Italian Way of Doing Industry; Public Administrations doing more with less; high reliability organizations; sustainable organizations; organization for social defence; new model of consumption; enterprises web 2.0.; broad professions.

Abstract:

The article highlights the general regularities of the economic development of commercial sea ports in the USSR and defines their role in industrialization of the country. For the first time there has been carried out a comparative analysis of sea port cargo turnover dynamics in relation to the ports of Great Britain, Germany, Italy, the Netherlands, the USA and France. The rates of port cargo turnover growth are investigated in comparison with the rates of industrial production growth, the volume of railway and inland water transport. The changes in the main cargo flows connected to the industrialization of the economy in all sea basins of the USSR have been studied. The dynamics of different types of cargo transshipment has been investigated. There has been stated the increasing rate of coastal cargo transshipment against the significant decrease in the export-import cargo transshipment due to the policy of self-reliance. The structure of foreign commercial cargos has been studied, a significant excess of exports over imports has been revealed. It has been found that the high growth rates of cargo turnover in the Soviet ports were due to the increase in the volume of oil cargo transshipment in the ports of the Caspian Sea. There have been calculated the average age and deadweight of Soviet ships in 1939, compared to the similar average international parameters and figures of the previous years. It was determined how the port's technical characteristics and lack of funding influenced these parameters. Investments to the seaports were hundreds of times less than investments to heavy industry and railway transport, and dozens of times less in inland waterways, since the seaports were not the priority objects in the program of economic industrialization. As a result, plans were not fulfilled, ships were idling in the ports, and labor productivity was low. It has been inferred that the activity of seaports during the first five-year plans was not profitable. There have been studied the specific features of the state system of seaports management during the first five-year plans.

Abstract:

Purpose This paper aims to explore if firms located in industrial districts (IDs) have different adoption paths concerning Industry 4.0 technologies and get different results with respect to other similar firms located outside IDs. Design/methodology/approach The study is based on a quantitative analysis related to an original data set of 206 Italian manufacturing firms specializing in made in Italy industries and adopting Industry 4.0 technologies. A case study of a district firm is also presented to explain the rationale of investment strategies and results obtained. Findings The analysis shows that there are differences between district and non-district firms when Industry 4.0 technology investments are concerned (higher investment rate in big data/cloud and augmented reality for district firms than non-district ones). In contrast to a breakthrough view of the fourth industrial revolution, the study suggests that 4.0 technologies emphasize the peculiarities and competitiveness factors typical of the district model in terms of customization and flexibility. There are differences in the motivations of adoption (product diversification for district firms vs productivity enhancement for non-district firms) and in the results achieved. Originality/value The paper is one of the first attempts to empirically explore the technological innovation paths related to Industry 4.0 within IDs, therefore, contributing to the debate on the possible evolution of the district model

Abstract:

The goal of this study was to compare the technical and economic performance of terrain chipping and roadside chipping, applied to short rotation biomass plantations. The null hypothesis was that no significant difference are in the performance of the two work systems, when applied to short rotation coppices. Those systems especially designed for non-industrial SRF plantations, were used for conventional logging operations. The difference on the above mentioned systems consisted especially in the chipping location: chipping was performed directly to the field (containers reach the chipper in the field) or at the field’s edge (roadside chipping). Both systems were tested on two of the most common SRF poplar clones in Italy, namely: AF2 and Monviso. Plots were allocated randomly to the two treatment levels ( roadside or field chipping) than blocked for two main clone types ( AF2 and Monviso ) so that each of the 4 treatments level and clone types has a minimum repetition plot of 6 times (total of 24 replications). The Plot were identified with paint markings at the stump so each plot area could be identified at the ground. Net weight of each charge was obtained by a certified weighbridge, so each plot has its own productivity in terms of weight and time consumption. Results were encouraging: harvesting cost varied from 16.3 to 23.2 􀀔 tonne-1, and was lower for terrain chipping and for the most productive clone (Monviso). Despite its higher cost, roadside chipping was preferred for its better terrain capability and for the superior storage quality of uncomminuted biomass. Both systems were suboptimal in their current configurations. They could offer a better performance, subject to minor improvements.

Abstract:

The globalization of the tobacco production has led to a drop in competitiveness of the Italian tobacco on the world market. Burley is the main variety of tobacco cropped in Campania region of Southern Italy. Its leaves have to be sewn, in the curing phase. Aim of this work is to show the results of the implementation of a new harvest machine prototype. Basically, the machine used for Bright tobacco, totally mechanical harvested, which doesn’t need to be sewn because it requires an indirect-fire treatment into the curing furnaces. The machine was modified in order to mechanize harvesting of Burley tobacco, and tested on four cultivars of Burley tobacco under three different planting layouts. The Burley tobacco leaves can be harvested mechanically by pulling individual leaves off the stalk; leaves are then sorted and tied in bundles prior to sewing. A mechanical burley tobacco harvesting system was evaluated. This machine consists in realizing a leaves orientation system based on the different weight between the leaf blade and the stalk enhanced by an air flow. The measurements taken were harvest timing, work capacity, and quality standards of the work carried out. The results, in terms of user time, range from 6.67 h/ha to 7.80 h/ha while in terms of operational efficiency are between 88% and 89%. The average user capacity recorded for the four cultivars is equal to 0.14 ha/h, a value far from the one recorded for the same harvesting machine used for Bright tobacco (0.25 ha/h). The harvest timing capacity, range from 0.51 t/h to 0.99 t/h. The work productivity goes from 0.17 t to 0.33 t per hour of human unit respectively. The average number of detached leaves, depending on the cultivar, has been between 523 and 744. Concerning the leaf orientation, a general percentage of 73% was achieved.

Abstract:

The competition for freshwater between agricultural, industrial, and civil uses has greatly increased in Mediterranean basin characterized by prolonged dry seasons. The aim of this study was to evaluate biomass production and the potential ethanol production of promising “no-food” herbaceous crops irrigated with low quality water at different ETc restitutions (0%, 50 and 100%). The research was carried out, in 2011 and 2012, in an open field near the full-scale constructed wetland (CW) municipal treatment plant located in the Eastern Sicily (Italy). The CW effluent has been applied in a experimental irrigation field of Vetiveria zizanoides (L.) Nash, Miscanthus x giganteus Greef et Deu. and Arundo donax (L.). Physical, chemical and microbiological analyses were carried out on wastewater samples collected at inlet and outlet of CW and pollutant removal efficiencies were calculated for each parameter. Bio-agronomical analysis on herbaceous species were made with the goal to evaluate the main parameters such as the plant dimension, the growth response and the biomass production. Biomass dry samples were processed with a three-step chemical pretreatment, hydrolysed with a mix of commercial enzymes and next fermented to obtain the yield of ethanol production. Average TSS, COD and TN removal for CW were about 74%, 67% and 68%, respectively. Although the satisfactory Escherichia coli removal, about 3.5 log unit for both beds on average, CW didn’t achieve the restrictive Italian law limits for wastewater reuse. As expected, irrigation was beneficial and the full ET replenishment increase the biomass productivity as compared to the other two treatment. The mean productivity of Vetiveria zizanoides and Myscanthus x giganteus were about 9, 26 and 38 t ha–1 and 3, 7 and 12 t ha–1 respectively in 0%, 50% and 100% ETc restitutions. Arundo donax gave higher values of dry biomass (78 t ha–1 in 100% ETc restitution in 2011 season), and potential ethanol production (about 3,744 kg ha–1). These results suggest the interest in the use of constructed wetland effluents for the irrigation of energy crops to obtain second generation ethanol, particularly in semiarid regions such as the Mediterranean area.

Abstract:

Баклажан имеет широкое распространение на юге России. Площади под культурой имеют тенденцию к росту. Кроме открытого грунта баклажан возделывают в утепленном и защищенном грунте, расширяются и направления использования продукции. Значительные объемы плодов в свежем виде и после промышленной переработки вывозят в более северные регионы. Для каждого направления использования и способа возделывания требуется соответствующий сортимент с комплексом нужных признаков и свойств. Привлечение нового исходного материала позволяет решить основные задачи селекции. Наибольшие перспективы имеет создание исходного материала с высокой продуктивностью в условиях разных способов возделывания, имеющего устойчивость к комплексу неблагоприятных биотических и абиотических факторов среды, лежкого и транспортабельного, пригодного для различных направлений использования и с комплексом морфологических признаков, улучшающих его технологичность в производстве. При выполнении селекционных программ наблюдается недостаток генисточников многих признаков и свойств. Это потребовало проведения специальных исследований по привлечению нового исходного материала. В задачи исследований входили как сбор коллекционного материала, так и его оценка на наличие ценных признаков, создание источников и доноров этих признаков и формирование на их основе банка генплазмы, вовлечение их в селекционный процесс. Исследования проведены в Селекционно-семеноводческом центре Ростовский Агрохолдинга Поиск в 2010-2019 годах в открытом грунте и весенних теплицах. Почвы в опытах черноземы обыкновенные. Погодные условия в годы проведения опытов были типичными для климатической зоны юга России. Лето было жарким и сухим, с продолжительными периодами полного отсутствия осадков при температурах свыше 30 С. Сумма активных температур за вегетационный период превышала 3500 С, а сумма осадков в среднем составляла 280 мм. Применялись технологии выращивания баклажан, принятые в регионе. Исходный материал изучали по стандартным методикам. На основе проведенных исследований был собран разнообразный материал из разных регионов мира, прежде всего из стран, где культура баклажан наиболее развита (Китай, Индия, Таиланд, Италия, Турция Голландия, Япония и др.). Собранные сорта и гибриды оценивали по наличию ценных признаков и свойств, на их основе создавался линейный материал источников и доноров признаков, востребованных в селекционных программах. Из лучших линий сформирован банк источников и доноров наиболее важных признаков коллекция генетической плазмы в количестве 70 образцов. Эта коллекция активно вовлечена в селекционные программы по созданию сортимента для юга России и на ее базе получено более 10 сортов и гибридов баклажан, отличающихся по направлениям использования, способам выращивания, с высокой продуктивностью и адаптивными качествами.Eggplant is widespread in southern Russia. Areas under the crop tend to grow. In addition to the open ground, the eggplant is cultivated in the comforted and protected soil, and the directions of use of products are expanded. Significant volumes of fruit in fresh form and after industrial processing are exported to more northern regions. Each use and method of cultivation requires an appropriate cultivar with a set of the right features and properties. Attracting new source material allows to solve the main problems of selection. The greatest prospects are the creation of the source material with high productivity in the conditions of different ways of cultivation, which is resistant to a set of adverse biotic and abiotic factors of the environment, lying and transportable, suitable for various uses and with a set of morphological features that improve its technological in production. In the implementation of breeding programs there is a lack of genetic sources of many signs and properties. This required special research to include new source material. The tasks of the research included both collecting the collection material and assessing it for the presence of valuable features, creating sources and donors of these traits and forming a gene plasma bank based on them, involving them in the breeding process. The research was carried out at the Rostovskii Breeding Centre of The Poisk Agro Holding in 2010-2019 in the open ground and spring greenhouses. Soils in experiments are ordinary blackearths. Weather conditions during the years of experiments were typical for the climate zone of southern Russia. Summer was hot and dry, with long periods of complete lack of precipitation in temperatures over 30 C. The amount of active temperatures during the growing season exceeded 3500 C, and the amount of precipitation averaged 280 mm. The technologies of eggplants growing adopted in the region were used. Based on the research, a variety of material was collected from different regions of the world, primarily from the countries where the eggplant culture is most developed (China, India, Thailand, Italy, Turkey Holland, Japan, etc.). Collected cultivars and hybrids were evaluated on the presence of valuable features and properties, on their basis created linear material of sources and donors of traits in demand in breeding programs. From the best lines formed a bank of sources and donors of the most important features - a collection of genplasma in the number of 70 samples. This collection is actively involved in breeding programs to create a variety for southern Russia and on its basis received more than 10 cultivars and hybrids of eggplant, differing in terms of use, methods of cultivation, with high productivity and adaptive qualities.

Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

Lartsev,Dmitrii A. Rasputin,Sergey D. Zuev-Ratnikov,Pavel V.Ryzhov,Dmitry S. Kudashev,Anton A. Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

Belyayeva,Fatima S. Datieva,Larisa R. Datieva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00046 Abstract: The aim of this work was to assess the functional reserves of the body to quantify individual health; adaptation, psychophysiological characteristics of the health quality of medical students in different seasons of the year. When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
