    This study assesses the current patterns and levels of exposure to rubber fume and rubber process dust in the British rubber industry and compares and contrasts the data obtained from the general rubber goods (GRG), retread tire (RT) and new tire (NT) sectors. A total of 179 rubber companies were visited and data were obtained from 52 general rubber goods, 29 retread tire and 7 new tire manufacturers. The survey was conducted using a questionnaire and included a walk-through inspection of the workplace to assess the extent of use of control measures and the nature of work practices being employed. The most recent (predominantly 1995-97) exposure monitoring data for rubber fume and rubber process dust were obtained from these companies; no additional sampling was conducted for the purpose of this study. In addition to the assessment of exposure data, evaluation of occupational hygiene reports for the quality of information and advice was also carried out.A comparison of the median exposures for processes showed that the order of exposure to rubber fume (E, in mg m(-3)) is: E(moulding) (0.40) approximately E(extrusion) (0.33)>E(milling) (0.18) for GRG; E(press) (0. 32)>E(extrusion) (0.19)>E(autoclave) (0.10) for RT; and E(press) (0. 22) approximately E(all other) (0.22) for NT. The order of exposure to rubber fume between sectors was E(GRG) (0.40)>E(RT) (0.32)>E(NT) (0.22). Median exposures to rubber process dust in the GRG was E(weighing) (4.2)>E(mixing) (1.2) approximately E(milling) (0.8) approximately E(extrusion) (0.8) and no significant difference (P=0. 31) between GRG and NT sectors. The findings compare well with the study carried out in the Netherlands [Kromhout et al. (1994), Annals of Occupational Hygiene 38(1), 3-22], and it is suggested that the factors governing the significant differences noted between the three sectors relate principally to the production and task functions and also to the extent of controls employed. Evaluation of occupational

    Following chapter presents short introductory description of rubber and rubber industry. The main problem of rubber industry is the way of the usage of spent tires. Furthermore very important group of problems arise considering the metal and nonmetal additives which are significant component of the vulcanized rubber. The key attention is dedicated to typical ways of rubber usage in utilization and recovery of metals from spent rubber materials concentrating specifically on used tires processing. The method of recovery of rare metals from rubber tires was described. The rubber debris finds widest use in the field of waste metal solutions processing. The environmental pollution caused by metals poses serious threat to humans. Several applications of the use of waste rubber debris to remove metals from environmental waters were described. Moreover, the agriculture usage of waste tire rubber debris is described, presenting systems where the rubber material can be useful as a soil replacement.

    The production of complex organic shapes in sheet metals is gaining more importance in the food industry due to increasing functional and hygienic demands. Hence it is necessary to produce parts with complex geometries promoting cleanability and general sanitation leading to improvement of food safety. In this context, and especially when stainless steel has to be formed into highly complex geometries while maintaining desired surface properties, it is inevitable that alternative manufacturing processes will need to be used which meet these requirements. Rubber pad forming offers high potential when it comes to shaping complex parts with excellent surface quality, with virtually no tool marks and scratches. Especially in cases where only small series are to be produced, rubber pad forming processes offers both technological and economic advantages. Due to the flexible punch, variation in metal thickness can be used with the same forming tool. The investments to set-up Rubber pad forming is low in comparison to conventional sheet metal forming processes. The process facilitates production of shallow sheet metal parts with complex contours and bends. Different bending sequences in a multiple tool set-up can also be conducted. The planned contribution thus describes a brief overview of the rubber pad technology. It shows the prototype rubber pad forming machine which can be used to perform complex part geometries made from stainless steel (1.4301). Based on an analysis of the already existing systems and new machines for rubber pad forming processes, together with their process properties, influencing variables and areas of application, some relevant parts for the food industry are presented.

    Increased cancer risks have been reported among workers in the rubber manufacturing industry employed before the 1960s, but it is unclear for workers hired subsequently. The present study focused on cancer incidence among rubber workers first employed after 1975 in Sweden and the UK. Two cohorts of rubber workers employed for at least 1 year were analysed. Standardised incidence ratios (SIRs), based on country-specific and period-specific incidence rates, were analysed for all cancers combined (except non-melanoma skin), bladder, lung, stomach cancer, leukaemia, non-Hodgkin's lymphoma and multiple myeloma. Exploratory analyses were conducted for other cancers with a minimum of 10 cases in both genders combined. 16 026 individuals (12 441 men; 3585 women) contributed to 397 975 person-years of observation, with 846 cancers observed overall (437 in the UK, 409 in Sweden). No statistically significant increased risk was observed for any site of cancer. A reduced risk was evident for all cancers combined (SIR=0.83, 95% CI (0.74 to 0.92)), lung cancer (SIR=0.74, 95% CI (0.59 to 0.93)), non-Hodgkin's lymphoma (SIR=0.67, 95% CI (0.45 to 1.00)) and prostate cancer (SIR=0.77, 95% CI (0.64 to 0.92)). For stomach cancer and multiple myeloma, SIRs were 0.93 (95% CI (0.61 to 1.43)) and 0.92 (95% CI 0.44 to 1.91), respectively. No increased risk of bladder cancer was observed (SIR=0.88, 95% CI (0.61 to 1.28)). No significantly increased risk of cancer incidence was observed in the combined cohort of rubber workers first employed since 1975. Continued surveillance of the present cohorts is required to confirm absence of long-term risk and confirmatory findings from other cohorts would be important.

    Some physical and mechanical properties of oriented strandboards (OSBs) containing waste tire rubber at various addition levels based on the oven-dry strand weight, using the same method as that used in the manufacture of OSB. Two resin types, phenol-formaldehyde (PF) and polyisocyanate, were used in the experiments. The manufacturing parameters were: a specific gravity of 0.65 and waste tire rubber content (10/90, 20/80 and 30/70 by wt.% of waste tire rubber/wood strand). Average internal bond values of PF-bonded OSB panels with rubber chips were between 17.6% and 48.5% lower than the average of the control samples while polyisocyanate bonded OSBs were 16.5-50.6%. However, water resistance and mechanical properties of OSBs made using polyisocyanate resin were found to comply with general-purpose OSB minimum property requirements of EN 300 Type 1 (1997) values for use in dry conditions at the lowest tire rubber loading level (10%) based on the oven-dry panel weight. The tire rubber improved water resistance of the OSB panel due to its almost hydrophobic property. Based on the findings obtained from this study, we concluded that waste tire rubber could be used for general-purpose OSB manufacturing up to 10% ratio based on the oven-dry panel weight.

  9. Rubber - application of radiation to tire manufacture

    Since the advent of commercial accelerators during the last several years capable of producing controllable electron beams of high energy, Firestone has devoted a considerable effort to the better understanding of the possible applications of such radiation to the production of tires or tire components. A number of chemical reactions can occur when elastomeric compounds are exposed to high energy waves, but crosslinking and degradation are the most important. The degree to which the crosslinking reaction predominates depends upon the nature of the rubber, compounding ingredients and the dosage. In general then, the effects achieved by the radiation of a rubber are quite similar to those resulting from heat. However, radiation cure or precure of compounds offers the advantage that the degree of crosslinking can be better controlled. Uniform crosslinking is possible since the high speed electrons penetrate uniformly throughout the sample. Curing with heat on the other hand may result in a greater degree of crosslinking on the surface of the sample than the center because of low heat conductivity. In general, radiation can be used to advantage to crosslink partially rubber tire components so that they retain better their shape and dimension during tire assembly and final cure or vulcanization. Added advantages of radiation precure include: a reduction of material usage, substitution of synthetic for natural rubber without loss in strength and the fact that partially crosslinked components will not thin out or become displaced during construction and vulcanization of the tire.

    2017-12-01

    The paper investigates the production and processing of halide-modified chlorinated rubbers, such as isobutylene isoprene rubber and ethylene-propylene-diene-monomer rubber (IIR and EPDM), which are perspective in terms of application in rubber industry. Prospects for their production and application are determined by the specific properties of these rubbers (low gas permeability of IIR, high heat and ozone resistance of EPDM). These properties are governed by the structure of both initial IIR and EPDM and chlorinated rubbers (ChIIR and ChEPDM). A new alternative technology of obtaining chlorinated elastomers based on solid-phase mechanochemical halide modification is proposed. Novel chlorinated polyolefin rubbers obtained by the developed technology show good technological properties under industrial production conditions due to enhanced covulcanization.

    Full Text Available Currently, much attention is paid to development, allowing use of waste and by-products formed during certain manufacturing processes. This allows you to either reduce or completely eliminate the use of valuable and expensive raw materials. The use of this raw material in the production of synthetic rubber will not only reduce the cost of coagulation and acidifying agents, but also to improve the environmental situation. Featured in some cases effective coalescing agents based on polymeric quaternary ammonium salts (PCHSA have a high coagulating power, and hence low consumption of the allocation of the rubber latex (3-5 kg0t-1 rubber. Scarcity and high cost of these drugs leads to higher prices resulting rubber. Furthermore it is known that the application requires keeping PCHSA sufficiently precise dosage administered substances by the action of a latex, owing to the high capacity of the antiseptic may lead to discharge into natural waters polluted waters. However, using as the coagulating agent departing sugar production molasses solves a number of problematic steps in the production of synthetic rubber.

    2018-03-01

    Sustainable maintenance is a new challenge for manufacturing companies to realize sustainable development. In this paper, an interpretive structural model is developed to evaluate sustainable maintenance in the rubber industry. The initial key performance indicators (KPIs) is identified and derived from literature and then validated by academic and industry experts. As a result, three factors of economic, social, and environmental dividing into a total of thirteen indicators are proposed as the KPIs for sustainable maintenance evaluation in rubber industry. Interpretive structural modeling (ISM) methodology is applied to develop a network structure model of the KPIs consisting of three levels. The results show the economic factor is regarded as the basic factor, the social factor as the intermediate factor, while the environmental factor indicated to be the leading factor. Two indicators of social factor i.e. labor relationship, and training and education have both high driver and dependence power, thus categorized as the unstable indicators which need further attention. All the indicators of environmental factor and one indicator of social factor are indicated as the most influencing indicator. The interpretive structural model hoped can aid the rubber companies in evaluating sustainable maintenance performance.

    The main issue related to this research was to examine the feasibility of natural rubber SMR 20 in the manufacturing of cement mortar for sub-base layer construction. Subbase layers have certain functions that need to be fulfilled in order to assure strong and adequate permeability of pavement performance. In a pavement structure, sub-base is below the base and serves as the foundation for the overall pavement structure, transmitting traffic loads to the sub-grade and providing drainage. Based on this research, the natural rubber, SMR 20 was with the percentages of 0%, 5%, 10% and 15% to mix with sand in the manufacture of the cement mortar. This research describes some of the properties and cost of the materials for the natural rubber and sand in cement mortar manufacturing by laboratory testing. Effects of the natural rubber replacement on mechanical properties of mortar were investigated by laboratory testing such as compressive strength test and density. This study obtained the 5% of natural rubber replaced in sand can achieved the strength of normal mortar after 7 days and 28 days. The strength of cement mortar depends on the density of cement mortar. According to the cost of both materials, sand shows the lower cost in material for the cement mortar manufacturing than the uses of natural rubber. Thus, the convectional cement mortar which used sand need lower cost than the modified rubber cement mortar and the most economical to apply in industrial. As conclusion, the percentage of 5% natural rubber in the cement mortar would have the same with normal cement mortar in terms of the strength. However, in terms of the cost of the construction, it will increase higher than cost of normal cement mortar production. So that, this modified cement mortar is not economical for the road sub-base construction.

    The paper provides for the relevance of various industrial waste treatment and application, as well as their secondary commercialization. It considers treatment of secondary polymer materials turning to additives applied in rubber production, in particular, in production of conveyor and V-type belts used in mechanical engineering. It is found that oligomers obtained from petroleum by-products can be used as an impregnating compound for fiber materials. Such adhesive treatment prior to introduction of impregnating compounds into elastomeric materials improves adhesion and complements performance of obtained composites.

    The word "rubber" immediately brings to mind materials that are highly flexible and will snap back to their original shape after being stretched. In this chapter a variety of materials are discussed that possess this odd characteristics. There will also be a discussion on the mechanism of this "elastic retractive force." Originally, rubber meant the gum collected from a tree growing in Brazil. The term "rubber" was coined for this material by the English chemist Joseph Priestley, who noted that it was effective for removing pencil marks from paper. Today, in addition to Priestley's natural product, many synthetic materials are made that possess these characteristics and many other properties. The common features of these materials are that they are made up of long-chain molecules that are amorphous (not crystalline), and the chains are above their glass transition temperature at room temperature.

    Most data on carcinogenic risk in the rubber industry are based on data from Western countries. This study assessed cancer risks in a retrospective cohort in a Polish tire manufacturing plant, relying on quantified exposure to inhalable aerosols and aromatic amines instead of job titles or external comparisons. Cumulative exposure for all exposures was assigned to cohort members based on estimates from a company-specific JEM. Cancer risks associated with cumulative exposure adjusted for co-exposures, gender and year of birth were calculated. Exposure levels were higher for women than for men. Aromatic amine exposure was significantly associated with increased urinary bladder cancer risk (RR=7.32-8.27), depending on exposure level, and prostate cancer at low levels only (RR=5.86). In women, increased risks were found for all cancers (RR=2.50) and of the digestive organs and peritoneum (RR=4.54) at low level only, while an exposure-response association with breast cancer risk was found. Inhalable aerosol exposure was associated with cancers of the liver and intrahepatic bile ducts in a dose-dependent manner, while dose-dependent reduced risks were found for respiratory cancers (most notably the larynx) and cancer of the colon. Increased risks for specific cancer sites in this rubber plant were similar to Western Europe and the US. However, several cancer risks were gender-specific which could relate to higher exposure levels in women or to differences in exposures to chemicals not assessed in this study.

  15. Creep and Recovery Behaviour of Polyolefin-Rubber Nanocomposites Developed for Additive Manufacturing

    Full Text Available Nanocomposite application in automotive engineering materials is subject to continual stress fields together with recovery periods, under extremes of temperature variations. The aim is to prepare and characterize polyolefin-rubber nanocomposites developed for additive manufacturing in terms of their time-dependent deformation behaviour as revealed in creep-recovery experiments. The composites consisted of linear low density polyethylene and functionalized rubber particles. Maleic anhydride compatibilizer grafted to polyethylene was used to enhance adhesion between the polyethylene and rubber; and multi-walled carbon nanotubes were introduced to impart electrical conductivity. Various compositions of nanocomposites were tested under constant stress in creep and recovery. A four-element mechanistic Burger model was employed to model the creep phase of the composites, while a Weibull distribution function was employed to model the recovery phase of the composites. Finite element analysis using Abaqus enabled numerical modelling of the creep phase of the composites. Both analytical and numerical solutions were found to be consistent with the experimental results. Creep and recovery were dependent on: (i composite composition; (ii compatibilizers content; (iii carbon nanotubes that formed a percolation network.

    Full Text Available Since the early 1990s the Romanian manufacturing industry has improved in many ways. This headway concerns the labour-intensive sector rather than the technology-intensive one. Apart from local entrepreneurship, foreign direct investments (FDI have been instrumental in enhancing industrial competitiveness. TheLisbon Agenda revival and Romania’s EU accession will be further inducements for Western businesses to shift production here to fight back both low-cost producers (typically from emerging Asia and more quality-oriented producers (typically from OECD countries. Hopefully, the FDI spillover effects will send positive vibrationsacross the economy, and tone down the asymmetry at the core of the manufacturing industry.

    Full Text Available Ergonomic conditions in small manufacturing industries were investigated. Twenty seven managers of small manufacturing industries participated in the study. Old equipment and machines, poorly designed workplaces, lack of systematic planning, layout and organization, unsafe working conditions and poor environment were found common to these industries. Fifty-nine percent of companies indicated having equipment older than 15 years. Fifty-two percent of company managers reported receiving complaints of fatigue from their workforce, 41% complaints of back pain, and 33% complaints of upper-body pain. Seventy eight percent of companies reported a noisy environment (above 90 dBA while 63% reported a hot environment. Management in 44% of the companies acknowledged failure to ensure safety rules and 48% did not provide training on manual material handling. Lack of skills in ergonomics and training, communication and resources are believed to be some of the factors contributing to the poor ergonomic conditions in a sample of small manufacturing industries in Malaysia.

    Many nitrosamines are suspected of being human carcinogens, with the highest concentrations in the environment being measured in the rubber industry. Time trends of personal exposure to N-nitrosodimethylamine (NDMA) and to N-nitrosomorpholine (NMor) during the past two decades in the German rubber industry were analysed and compared with cross-sectional studies in the same period in the Netherlands, Poland, the UK and Sweden. In the majority of the surveyed departments exposures reduced over time, but considerable heterogeneity was present between departments and sectors. Significant reductions were primarily found in curing and post-treating departments and ranged from -3% year(-1) to -19% year(-1). In contrast, NDMA levels increased (+13% year(-1)) in maintenance and engineering in the tyres industry. Average NDMA-levels in general rubber goods (GRG) and NMor-levels in tyre production in Germany did not decrease significantly in the past two decades, whereas NDMA-levels in tyre production (-10% year(-1)) and NMor-levels in GRG (-7% year(-1)) declined significantly after the introduction of an exposure limit for total nitrosamines in Germany in 1988. Confidence intervals of average exposures in other studied countries largely overlap trends observed in Germany. Exposure to N-nitrosamines decreased on average two-to-five fold in the German rubber industry with comparable concentration levels in other European countries. Although average levels are well below the current limits exposure has not been eliminated, and incidental high exposures do still occur.

    Multi-objective optimization was used to evaluate the effect of adding banana (Musa paradisiaca L.) starch and natural rubber (cis-1,4-poliisopreno) at different ratios (1-13w/w) to the manufacturing process of biodegradable films, specifically the effect on the biodegradability, crystallinity and moisture of the films. A structural characterization of the films was performed by X-ray diffraction, Fourier transform infrared spectroscopy and SEM, moisture and biodegradability properties were studied. The models obtained showed that degradability vs. moisture tend to be inversely proportional and crystallinity vs. degradability tend to be directly proportional. With respect to crystallinity vs. moisture behavior, it is observed that crystallinity remains constant when moisture values remain between 27 and 41%. Beyond this value there is an exponential increase in crystallinity. These results allow for predictions on the mechanical behavior that can occur in starch/rubber films.

    2016-09-01

    Full Text Available Purpose: Lean Manufacturing is widely regarded as a potential methodology to improve productivity and decrease costs in manufacturing organisations. The success of lean manufacturing demands consistent and conscious efforts from the organisation, and has to overcome several hindrances. Industry 4.0 makes a factory smart by applying advanced information and communication systems and future-oriented technologies. This paper analyses the incompletely perceived link between Industry 4.0 and lean manufacturing, and investigates whether Industry 4.0 is capable of implementing lean. Executing Industry 4.0 is a cost-intensive operation, and is met with reluctance from several manufacturers. This research also provides an important insight into manufacturers’ dilemma as to whether they can commit into Industry 4.0, considering the investment required and unperceived benefits. Design/methodology/approach: Lean manufacturing is first defined and different dimensions of lean are presented. Then Industry 4.0 is defined followed by representing its current status in Germany. The barriers for implementation of lean are analysed from the perspective of integration of resources. Literatures associated with Industry 4.0 are studied and suitable solution principles are identified to solve the abovementioned barriers of implementing lean. Findings: It is identified that researches and publications in the field of Industry 4.0 held answers to overcome the barriers of implementation of lean manufacturing. These potential solution principles prove the hypothesis that Industry 4.0 is indeed capable of implementing lean. It uncovers the fact that committing into Industry 4.0 makes a factory lean besides being smart. Originality/value: Individual researches have been done in various technologies allied with Industry 4.0, but the potential to execute lean manufacturing was not completely perceived. This paper bridges the gap between these two realms, and identifies

    Natural rubber is an important strategic raw material for manufacturing a wide variety of industrial products. There are at least 2,500 different latex-producing plant species; however, only Hevea brasiliensis (the Brazilian rubber tree) is a commercial source. The chemical structure of natural rubber is cis-1,4-polyisoprene, but the exact structure of the head and end groups remains unknown. Since synthetic cis-1,4-polyisoprenes cannot match the superior properties of natural rubber, understanding the chemistry behind the biosynthetic process is key to finding a possible replacement. T his chapter summarizes our current understandings from the perspective of a polymer scientist by comparing synthetic polyisoprenes to natural rubber. The chapter also highlights biomimetic polymerization, research towards a synthetic match of natural rubber and the role of natural rubber in health care.

    Full Text Available Residential construction consumes an estimated 26 percent of the total U.S. wood harvest and thus plays an important role in the forest products value chain. While being a relatively small part of the U.S. residential construction market, the factory-built residential housing industry, originating from manufactured homes (e.g. mobile homes, is embracing emerging industry segments such as modular or panelized homes. Since indications exist that factory-built home production is slated to gain a more prominent role in the U.S. construction markets at the cost of traditional stick-built production, the factory-built home industry sub-segment is of considerable importance to the forest products industry. This research looks at manufactured home producers as a benchmark for analyzing the current economic state of the industry and discusses competitive strategies. The analysis concludes, through macroeconomic modeling, that manufactured homes are in the declining stage of their product life cycle due to changes to the U.S. residential construction sector and the factory-built home industry and by advancements of rival industry-segments. As market share continues to decline, firms operating in this industry-segment seek to either hedge their losses through product diversification strategies or remain focused on strategically repositioning the manufactured home segment.

  17. Air purification in industrial plants producing automotive rubber components in terms of energy efficiency

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available In automotive industry plants, which use injection molding machines for rubber processing, tar contaminates air to such an extent that air fails to enter standard heat recovery systems. Accumulated tar clogs ventilation heat recovery exchangers in just a few days. In the plant in which the research was conducted, tar contamination causes blockage of ventilation ducts. The effect of this phenomenon was that every half year channels had to be replaced with new ones, since the economic analysis has shown that cleaning them is not cost-efficient. Air temperature inside such plants is often, even in winter, higher than 30°C. The air, without any means of heat recovery, is discharged outside the buildings. The analyzed plant uses three types of media for production: hot water, cold water at 14°C (produced in a water chiller, and compressed air, generated in a unit with a rated power consumption of 180 kW. The aim of the study is to determine the energy efficiency improvement of this type of manufacturing plant. The main problem to solve is to provide an air purification process so that air can be used in heat recovery devices. The next problem to solve is to recover heat at such a temperature level that it would be possible to produce cold for technological purposes without air purification. Experimental studies have shown that air purification is feasible. By using one microjet head, a total of 75% of tar particles was removed from the air; by using 4 heads, a purification efficiency of 93% was obtained. This method of air purification causes air temperature to decrease from 35°C to 20°C, which significantly reduces the potential for heat recovery. The next step of the research was designing a cassette-plate heat exchanger to exchange heat without air purification. The economic analysis of such a solution revealed that replacing the heat exchanger with a new one even once a year was not cost-efficient. Another issue examined in the context of

    Park, Sun-Young; Yoo, Seung-Hoon

    2013-01-01

    Although LNG is an important input to industrial production for manufacturing firms, its economic value has been rarely investigated in the literature. This paper attempts to estimate the economic value of LNG in Korea's manufacturing sector by employing the concept of the value of marginal product (VMP). For this, we used data on 328 firms using LNG as an input. Two types of production functions (the Cobb–Douglas and trans-log functions) are applied. The result of the specification test indicates that the trans-log function is more appropriate for estimating the data. The output elasticity and VMP of industrial LNG are estimated to be 0.1346 and KRW 6844 (USD 6.22) per m 3 , respectively. The results have important implications for various areas of industrial LNG management. For example, any cost–benefit analysis of new projects providing industrial LNG requires information on the economic value of industrial LNG. In addition, such information is useful for the Korean government's future policies on LNG pricing. - Highlights: • We estimate the economic value of LNG in the Korean manufacturing industry. • We employ the concept of the value of marginal product (VMP). • The VMP of industrial LNG is estimated to be KRW 6844 (USD 6.22) per m 3 . • It significantly outweighs the price of industrial LNG (KRW 629.4 per m 3 )

    Full Text Available 120 Purpose: The purpose of this paper is to characterize the cyclical phases of the manufacturing industry in Spain and detect which industries have more influence on the Spanish business cycle. We assume that economic growth is a priority; we are going to determine which industries have a more/less appropriate cyclical behavior according this priority. We analyze if the industries with better cyclical behavior are the ones that achieve greater co-movement with the business cycle of the Spanish economy, as this means they have a positive influence on economic activity. Design/methodology/approach: We examine the disaggregated quarterly IPI data of 16 manufacturing industries. Our methodology follows three steps. Firstly, we define cycle turning points; we follow the Harding and Pagan (2002 methodology. Secondly, we characterize the cyclical phases of the manufacturing industries in terms of duration, amplitude, deepness and steepness. We also determine the degree of inter-industrial cyclical synchronization and between industries in the cycle of the Spanish economy. This analysis is performed in two ways. On the one hand, we use the concordance index and the correlation coefficient. On the other hand, we work with indicators based on a consistency table. In the Third step, we apply a multi-objective methodology, specifically the compromise programming, to determine which industries have a more/less appropriate cyclical behavior according to the growth priority. Findings and Originality/value: The business cycle of the Spanish economy is positively influenced by high- and medium-tech industries, which have demonstrated their competitive capacity in international markets, and by medium- low-tech industries, with major strengths in R&D, and in survival and consolidation strategies. These results enable manufacturing industries to exert a positive effect on the business cycle that is weakened because many of them show a high correlation between

An environmental risk assessment model was developed based on the network analytic method and fuzzy set theory. The "interval analysis method" was applied to deal with the on-site monitoring data as basic information for assessment. In addition, the fuzzy set theory was employed to allow uncertain, interactive and dynamic information to be effectively incorporated into the environmental risk assessment. This model is a simple, practical and effective tool for evaluating the environmental risk of manufacturing industry and for analyzing the relative impacts of emission wastes, which are hazardous to both human and ecosystem health. Furthermore, the model is considered useful for design engineers and decision-maker to design and select processes when the costs, environmental impacts and performances of a product are taken into consideration.

  4. Industrial energy thrift scheme. Report No. 27. Energy use in the rubber, and linoleum and plastics floor-covering sectors

    Energy Technology Data Exchange (ETDEWEB)

    1981-05-01

    A total of 374 establishments manufacturing rubber products and 42 establishments producing linoleum or other coated substrates were invited to take part in the scheme, leading to 77 and 16 visits respectively. Both sectors manufacture products which contain as a main ingredient polymers of high molecular weight. For purposes of comparison, the different types of products have been grouped under five product headings: new tires, remoulded tires, solid rubber based products, latex based products, and coated substrates. Five sources of energy were used at the sites visited. Fuel oil was the main source, supplying 49 percent of the total, followed by gas with 25 percent. Coal, supplying only 10 percent of the total, contributed much less than it did in the past. Process wastes and reject products, used as fuels, contributed only 1.5 percent to the total supply of energy - but could supply much more. Within the 93 sites visited 760 opportunities for saving energy were noted; nineteen different types of opportunity were observed in at least 20 percent of the sites. Opportunities for saving energy, in descending order of significance, lay in the recovery of waste heat from manufacturing processes, in the reduction of heat loss from process equipment, in the improvement of insulation of buildings, in better control of space heating, and in the recovery of heat from the blowdown of boilers.

    2017-06-01

    Full Text Available The ultimate goal of a company is to build the enterprise value, which is achievable thanks to abnormal profits generated in particular period. Moreover, firms are expected to take measures to maintain abnormal profit in the future. On the other hand, abnormal profits attract competitors, who increase competition and as a result abnormal profits disappear. The persistence of profit is a term that describes a situation, when the company is successful in maintaining the abnormal profit over time. The main aim of this paper is to investigate the persistence of abnormal profit in Polish manufacturing sector. In other words, the question is whether Polish manufacturing companies are able to maintain their abnormal profits over time. The persistence of abnormal profits is investigated using dynamic panel model with generalized method-of-moments estimators. The method is applied to a panel of 5303 Polish companies from manufacturing sector observed over the period 2006-2014. This paper contributes to the existing literature in two ways. First, analysis is performed for developing country. Second, analysis is performed both at the level of entire sector and at division level. Three main conclusions can be drawn from the conducted research: there are significant differences between profit rates within the same industry at division level; estimated persistence of abnormal profit coefficients are at moderate level; there are substantial differences between estimated persistence of profit coefficients for divisions in the same industry.

    Full Text Available This empirical paper explores trends in innovation activities measured by a countries’ total patent application submission intensity relative to its population, and by analyzing U.S. granted patents data for cohorts of developed countries and developing countries. In addition to tabular and graphical analyses, I use a baseline regression model and a variant model thereof to assess the relative influence of a set of aggregate variables on innovation activities in eight manufacturing industries across two cohorts of countries (developed and developing where each cohort contains eight individual countries. Eight industries included in this study are: Chemical, Petroleum, electrical and electronics equipment, machinery, pharmaceutical, plastic, computer, and textile. The cohort of developed countries includes Australia, Canada, Czech Republic, France, Italy, Poland, Switzerland, and the United States. The cohort of developing countries includes Brazil, China, India, Malaysia, Mexico, Russia, South Africa, and Turkey. Per regression results, ethnic diversity is a statistically significant positive determinant of innovation for all industry aggregate patent count for both high income and developing countries. Also, per capita electricity usage, R&D expenditure as percent of GDP, and percent of population with internet access are three positive factors of innovation irrespective of industrial subsectors and position of a country in the development echelon. Interestingly, impact of ICT-services export is statistically significant and innovation boosting in developing countries in the cohort relative to countries in the cohort of developed countries. It also appears that trade openness served as a stronger stimulant of innovation activities for developing countries’ but not as much for the cohort of developed or high-income countries.

    Full Text Available Purpose: Global competition and ever changing customers demand have made manufacturing organizations to rapidly adjust to complexities, uncertainties, and changes. Therefore, flexibility in manufacturing resources is necessary to respond cost effectively and rapidly to changing production needs and requirements.  Ability of manufacturing resources to dynamically reallocate from one stage of a production process to another in response to shifting bottlenecks is recognized as resource flexibility. This paper aims to develop and validate resource flexibility measures for manufacturing industry that could be used by managers/ practitioners in assessing and improving the status of resource flexibility for the optimum utilization of resources. Design/methodology/approach: The study involves survey carried out in Indian manufacturing industry using a questionnaire to assess the status of various aspects of resource flexibility and their relationships. A questionnaire was specially designed covering various parameters of resource flexibility. Its reliability was checked by finding the value of Cronback alpha (0.8417. Relative weightage of various measures was found out by using Analytical Hierarchy Process (AHP. Pearson’s coefficient of correlation analysis was carried out to find out relationships between various parameters. Findings: From detailed review of literature on resource flexibility, 17 measures of resource flexibility and 47 variables were identified. The questionnaire included questions on all these measures and parameters. ‘Ability of machines to perform diverse set of operations’ and ability of workers to work on different machines’ emerged to be important measures with contributing weightage of 20.19% and 17.58% respectively.  All the measures were found to be significantly correlated with overall resource flexibility except ‘training of workers’, as shown by Pearson’s coefficient of correlation. This indicates that

    Hydrogels are a class of soft material that is exploited in many, often completely disparate, industrial applications, on account of their unique and tunable properties. Advances in soft material design are yielding next-generation moldable hydrogels that address engineering criteria in several industrial settings such as complex viscosity modifiers, hydraulic or injection fluids, and sprayable carriers. Industrial implementation of these viscoelastic materials requires extreme volumes of material, upwards of several hundred million gallons per year. Here, we demonstrate a paradigm for the scalable fabrication of self-assembled moldable hydrogels using rationally engineered, biomimetic polymer-nanoparticle interactions. Cellulose derivatives are linked together by selective adsorption to silica nanoparticles via dynamic and multivalent interactions. We show that the self-assembly process for gel formation is easily scaled in a linear fashion from 0.5 mL to over 15 L without alteration of the mechanical properties of the resultant materials. The facile and scalable preparation of these materials leveraging self-assembly of inexpensive, renewable, and environmentally benign starting materials, coupled with the tunability of their properties, make them amenable to a range of industrial applications. In particular, we demonstrate their utility as injectable materials for pipeline maintenance and product recovery in industrial food manufacturing as well as their use as sprayable carriers for robust application of fire retardants in preventing wildland fires.

    This paper investigates occupational health and safety practices in manufacturing enterprises within Jordanian industrial estates. Response rates were 21.9%, 58.6% and 70.8% for small, medium and large sized enterprises, respectively. Survey results show that most companies comply with state regulations, provide necessary facilities to enhance safety and provide several measures to limit and control hazards. On the negative side, little attention is given to safety training that might be due to the lack of related regulations and follow-up, financial limitations or lack of awareness on the importance of safety training. In addition, results show that ergonomic hazards, noise and hazardous chemicals are largely present. Accident statistics show that medium enterprises have the highest accident cases per enterprise, and chemical industries reported highest total number of accidents per enterprise. The outcomes of this study establish a base for appropriate safety recommendations to enhance the awareness and commitment of companies to appropriate safety rules.

    The primary goal of this study was to use the Strain Index (SI) to assess the risk of developing upper extremity musculoskeletal disorders in a television (TV) manufacturing industry and evaluate the effectiveness of an educational intervention. The project was designed and implemented in two stages. In first stage, the SI score was calculated and the Nordic Musculoskeletal Questionnaire (NMQ) was completed. Following this, hazardous jobs were identified and existing risk factors in these jobs were studied. Based on these data, an educational intervention was designed and implemented. In the second stage, three months after implementing the interventions, the SI score was re-calculated and the Nordic Musculoskeletal Questionnaire (NMQ) completed again. 80 assembly workers of an Iranian TV manufacturing industry were randomly selected using simple random sampling approach. The results showed that the SI score had a good correlation with the symptoms of musculoskeletal disorders. It was also observed that the difference between prevalence of signs and symptoms of musculoskeletal disorders, before and after intervention, was significantly reduced. A well conducted implementation of an interventional program with total participation of all stakeholders can lead to a decrease in musculoskeletal disorders.

    As nodes progress into the 7nm and below regime, extreme ultraviolet lithography (EUVL) becomes critical for all industry participants interested in remaining at the leading edge. One key cost driver for EUV in the supply chain is the reflective EUV mask. As of today, the relatively few end users of EUV consist primarily of integrated device manufactures (IDMs) and foundries that have internal (captive) mask manufacturing capability. At the same time, strong and early participation in EUV by the merchant mask industry should bring value to these chip makers, aiding the wide-scale adoption of EUV in the future. For this, merchants need access to high quality, representative test vehicles to develop and validate their own processes. This business circumstance provides the motivation for merchants to form Joint Development Partnerships (JDPs) with IDMs, foundries, Original Equipment Manufacturers (OEMs) and other members of the EUV supplier ecosystem that leverage complementary strengths. In this paper, we will show how, through a collaborative supplier JDP model between a merchant and OEM, a novel, test chip driven strategy is applied to guide and validate mask level process development. We demonstrate how an EUV test vehicle (TV) is generated for mask process characterization in advance of receiving chip maker-specific designs. We utilize the TV to carry out mask process "stress testing" to define process boundary conditions which can be used to create Mask Rule Check (MRC) rules as well as serve as baseline conditions for future process improvement. We utilize Advanced Mask Characterization (AMC) techniques to understand process capability on designs of varying complexity that include EUV OPC models with and without sub-resolution assist features (SRAFs). Through these collaborations, we demonstrate ways to develop EUV processes and reduce implementation risks for eventual mass production. By reducing these risks, we hope to expand access to EUV mask capability for

    The article analyzes the relationship between the extractive activity of elastic rubber, during the period between the fourth part of 19th century and the first decades of the 20 Th century, in the Amazonian frontier between Brazil, Peru and Colombia, and the process of configuration and definition of the boundaries between these countries. The central aspect of the analysis and the discussion is the questioning of the deterministic and simplistic interpretations that associate, in a mechanical way, the relationship between the kind of rubber species exploited and their production organization, the effects on the indigenous societies, and even the politic organization and delimitation of the bordering territories. It is also expected to show how these interpretations have been wrongly or instrumentally used even in the ideological field, to justify and explain the results of the bordering agreements of these countries, which conduced to establish the current Political frontiers in the Amazon

    About 673 small-scale asbestos mining and milling facilities and 33 large - scale asbestos manufacturing plants, (17 asbestos-cement product manufacturing plants and 16 other than asbestos-cement product plants) are situated in India. The present study reveals the exposure of commercial asbestos (chrysotile) in the occupational as well as ambient air environment of the asbestos-cement (AC) sheets industry using membrane filter method of Bureau of Indian Standards (BIS). The fibre concentrations in 15 samples collected in the occupational environment at ingredient feeding site, sheet-producing site, fibre godown were 0.079, 0.057 and 0.078 f/cc, respectively and in five samples from surrounding ambient air at factory gate resulted fibre concentration of 0.071 f/cc. All the samples have shown fibre concentration lower than the threshold limit values (TLVs) prescribed by BIS. Morphological analysis of samples, further under phase contrast and polarized microscopy indicates the presence of chrysotile asbestos, which acts as carcinogen as well as co-carcinogen. A clinical examination of exposed subjects reveals that there was no case of clubbing, crepitation, ronchi and dyspnea on exertion; however, obstruction and restriction were 10.9 per cent and 25 per cent in exposed subjects, respectively while in control there were 12 per cent and 28 per cent, respectively. The study revealed that chrysotile asbestos is emitted in the occupational as well as ambient environment that may cause adverse health impact.

    Full Text Available In the context of energy demands by growing economies, climate changes, fossil fuel pricing volatility, and improved safety and performance of nuclear power plants, many countries express interest in expanding or acquiring nuclear power capacity. In the light of the increased interest in expanding nuclear power the supply chain for nuclear power projects has received more attention in recent years. The importance of the advanced planning of procurement and manufacturing of components of nuclear facilities is critical for these projects. Many of these components are often referred to as long-lead items. They may be equipment, products and systems that are identified to have a delivery time long enough to affect directly the overall timing of a project. In order to avoid negatively affecting the project schedule, these items may need to be sourced out or manufactured years before the beginning of the project. For nuclear facilities, long-lead items include physical components such as large pressure vessels, instrumentation and controls. They may also mean programs and management systems important to the safety of the facility. Authorized nuclear operator training, site evaluation programs, and procurement are some of the examples. The nuclear power industry must often meet very demanding construction and commissioning timelines, and proper advanced planning of the long-lead items helps manage risks to project completion time. For nuclear components there are regulatory and licensing considerations that need to be considered. A national nuclear regulator must be involved early to ensure the components will meet the national legal regulatory requirements. This paper will discuss timing considerations to address the regulatory compliance of nuclear long-lead items.

    The main objective of the project is to investigate different types of molding rubbers used for investment casting. The level of shape complexity which can be achieved by using these rubber molds is also studied. It was almost impossible to make complex shapes molds using metal molds, in that cases rubber molds are very important because they arc flexible and give accurate and precise part dimensions. Turbine blades are hi-tech components with air-foil geometries that have close dimensional tolerances. They are made of super-alloys and manufactured by investment casting. The final blade profile depends upon the dimensional accuracy in each of the processing steps. In the present work experimental study for the production of high quality low cost castings of turbine blades using rubber molds and injected wax patterns is presented. Natural Rubber molds and wax patterns from these molds were made. Different types of molding rubbers were studied including natural rubber, silicone rubber and liquid silicone rubber. It was found that by using rubber molds we can make most complex shape with very less finishing required. The shrinkage was 12% as compared to original master pattern. Rubber molds were made using laboratory hot press. Three layers of rubber above and below the master pattern. After that vulcanization was done by giving temperature and pressure. (author)

    Inhalation of dusts and fumes arising during the manufacture of sodium dichromate from chrome ore, chromic acid mist emitted during electroplating, and skin contact with chromate produce hazards to workers. (1) To elucidate the prevalence of skin and mucous membrane disorders among the workers engaged in the sodium dichromate manufacturing industry and chrome plating industry. (2) To know the relationship of prevalence with the duration of exposure to chrome mist, dust, and fumes. A cross-sectional study was conducted among all the workers engaged in sodium dichromate manufacturing and chrome plating from several industries situated near the Delhi-Haryana border in the districts of Faridabad and Sonepat of Haryana, India from January 01, 2014 to December 31, 2014. All the workers available from the concerned industries for the study were interviewed and medically examined after obtaining their informed consent. A total of 130 workers comprising 66 workers from the sodium dichromate manufacturing industry and 64 workers from the chrome plating industry were examined on a pretested schedule. Descriptive statistical methods (proportions, relative risk, and Chi-square test of significance with P value analyzed using Epi Info version 7). All the workers were found to be males and of the adult age group. Out of the total examined, 69.69% and 56.22% of the workers had disorders of the nasal mucous membrane in the sodium dichromate manufacturing industry and the chrome plating industry, respectively. 42.42% and 28.22% of the workers had perforation of the nasal septum in the sodium dichromate manufacturing industry and chrome plating industry, respectively. 6.06% and 3.12% workers had skin ulcers in the sodium dichromate manufacturing industry and chrome plating industry, respectively. Nasal irritation and rhinorrhea were the most commonly found symptoms in both the processes. 48.48% and 90.52% of the workers were using hand gloves in the sodium dichromate manufacturing

    The records of 40 867 men employed for at least one year in the rubber and cablemaking industries have now been observed for eight years. This analysis compares the mortality pattern for 1972-74 with that previously reported for 1968-71. It indicates a significant excess of deaths due to cancer of the bladder throughout the industry including men who had not been exposed to acknowledged bladder carcinogens. This excess is in deaths occurring in 1973 and 1974 in the 45-64 and 65 years plus age groups. The two sectors of the industry where this excess is significant are footwear and footwear supplies except adhesives, and the tyre sector. The excess of all cancers taken together previously noted throughout the study population for 1968-71 is confirmed for 1972-74 as is the excess for lung cancers. The greater excess in the tyre sector is also confirmed, particularly in those men in the 55-64 year age group and those who entered the industry between 1950 and 1960. While men employed in 1967 on moulding, press, autoclave, and pan curing, and workers in finished goods, stores, packaging, and despatch continue to have more lung cancer deaths than expected for 1972-74, the excess is no longer statistically significant. An excess of cancer of the stomach which was overlooked in 1968-71 is not confirmed in 1972-74 but is nevertheless high when the total period of study 1968-74 is considered. The limitations of the study are discussed with particular reference to extrapolating the results to the whole industry. We conclude that there is a higher rate of lung cancer in the tyre sector of the industry and that immediate investigations are required to test the hypothesis concerning the recent excess of bladder cancers. Attention should now be paid to the control of exposures to all potential hazards in the industry.

    2016-03-01

    While metal additive manufacturing (AM) technology has clear benefits, there are still factors preventing its adoption by industry. These factors include the high cost of metal AM systems, the difficulty for machinists to learn and operate metal AM machines, the long approval process for part qualification/certification, and the need for better process controls; however, the high AM system cost is the main barrier deterring adoption. In this paper, we will discuss an America Makes-funded program to reduce AM system cost by combining metal AM technology with conventional computerized numerical controlled (CNC) machine tools. Information will be provided on how an Optomec-led team retrofitted a legacy CNC vertical mill with laser engineered net shaping (LENS®—LENS is a registered trademark of Sandia National Labs) AM technology, dramatically lowering deployment cost. The upgraded system, dubbed LENS Hybrid Vertical Mill, enables metal additive and subtractive operations to be performed on the same machine tool and even on the same part. Information on the LENS Hybrid system architecture, learnings from initial system deployment and continuing development work will also be provided to help guide further development activities within the materials community.

  4. Construction of corporate social performance indicators for Czech manufacturing industry

    2013-01-01

    Full Text Available This article aims to map out the level of social performance measurement of Czech companies, i.e. what social performance indicators companies monitor and what information they provide to their stakeholders and to construct alternative corporate social performance indicators. Based on an analysis of 24 corporate voluntary reports and results of an empirical research performed among 79 large companies operating in the manufacturing industry, it was found that companies partially monitor their social performance, but from the perspective of international standards (e.g. Global Reporting Initiative, International Federation of Accountants it is still insufficient. Czech companies usually provide only absolute numbers which disguise real trends and do not allow year on year comparison or comparison with other companies. Czech companies should provide a comprehensive picture of their overall performance, they should not focus only on financial indicators based on accounting data, since it is known that the performance measurement based only on financial and economic performance does not lead to long-term success and sustainability of organizations. Companies should monitor more their impact on society within which they operate. Proposed corporate social performance indicators in a measurable and thus manageable way express social issues.

It also participates in the debate on the competitiveness of manufacturing companies.

  6. Manufacturing technology in the Danish pig slaughter industry.

    Hinrichsen, Lars

    2010-02-01

    The Danish pig meat industry is very export oriented. Ninety per cent of the production of the big cooperative slaughterhouses is exported to more than 100 countries all over the world. This poses a requirement for the industry to be globally competitive in the sense of quality, product safety and--of course--price. A big challenge for the industry is therefore to maintain sufficient low unit costs in spite of the high factor costs of Denmark. In particular the high labour costs must be accompanied by correspondingly high labour productivity. And, it should be emphasized, this high labour productivity must be achieved without compromising the concern for good working conditions of the employees in the manufacturing. Technology is one of the means to achieve this combination of good working conditions and high labour productivity. One of the most important benefits from automation is the improved working environment. Pig slaughtering, cutting and boning is traditionally very labour intensive and requires hard and repetitive work. For many people a job in a slaughterhouse is therefore not their first choice. This situation can be changed by automation, which will not only reduce arduous and repetitive work but in addition will introduce more motivating jobs in terms of planning, supervision and control of the new technology. Automation will also improve the hygiene and thereby the food safety. This applies in particular to the clean slaughter line where cross contamination between carcasses is reduced because of less manual handling and because the tools in the machines can be sterilised more effectively between each carcass. Automated processes are more accurate and repeatable than manual work. For some processes, in particular in cutting and boning, this will enhance the product yield. New technology can also improve the animal welfare. The group-stunning system and mechanised lairage systems are examples of that. Improved animal welfare has an ethical value in

    A total of 67 workers were examined from the production of "Ethyl benzene-styrene" and 184 workers from the production of "Synthetic rubber and latex", as well as a control group of 59 employees. The workers from the first production are exposed to the effect of styrene, ethyl benzene and toluene. The concentrations of the substances surpass MAC, with several times, at the majority of the working places. The workers with a length of service over 10 years predominate. The workers from the second production are exposed to the combined effect of styrene and divinyl, their concentrations fluctuating from 2 to 8 times over MAC. The workers with a length of service over 10 years are 71.7%. The deviations, established in the hematological indices studied are compared with the results from a study on the workers from those productions of 6 years ago. Dynamics in the changes was established among the workers from the production of "Synthetic rubber and latex", associated with the duration of occupational exposure to styrene and divinyl. In case of a shorter length of service, the deviations are functional (reduction of peroxidase activity in granulocytes), increase of hemoglobin and hematocrit, associated with the adaptive reaction of organism. Pronounced anemic syndrome was established in a considerable number (24 workers) after an exposure of 10 years as well as lymphocytosis (35 subjects) and leukopenia (9 subjects).

    1993-01-01

    Synthetic rubber markets in North America bounced back in no uncertain terms last year, with demand climbing an impressive 9.5%, to 2.97 million m.t.; and, according to the International Institute of Synthetic Rubber Producers (IIS-RP; Houston) latest five-year forecast, producers can look forward to a 3.3% increase in demand during 1993. This growth rate outpaced out 1992 forecast and demonstrates the resilience of the synthetic rubber industry, says William E. Tessemer, managing director of IISRP. We expect demand in 1993 to surpass 1992 and level off at a 2%/year growth rate for synthetic rubber - 2.5% including thermoplastic elastomers [TPEs]-over the 1993-97 period. The improvement reflects signs of a recovery in North America, especially the pickup in the auto and tire industry. The two major tire rubbers - styrene butadiene and polybutadiene rubber - notched up double-digit gains, and other materials that have autos uses, such as nitrile rubber and many of the specialty elastomers, also advanced strongly

  16. Are the determinants of markup size industry-specific? The case of Slovenian manufacturing firms

    Directory of Open Access Journals (Sweden)

    Ponikvar Nina

    2011-01-01

    Full Text Available The aim of this paper is to identify factors that affect the pricing policy in Slovenian manufacturing firms in terms of the markup size and, most of all, to explicitly account for the possibility of differences in pricing procedures among manufacturing industries. Accordingly, the analysis of the dynamic panel is carried out on an industry-by-industry basis, allowing the coefficients on the markup determinants to vary across industries. We find that the oligopoly theory of markup determination for the most part holds for the manufacturing sector as a whole, although large variability in markup determinants exists across industries within the Slovenian manufacturing. Our main conclusion is that each industry should be investigated separately in detail in order to assess the precise role of markup factors in the markup-determination process.

    Rising energy costs and concerns over the environment have contributed to a renewed focus on recycling for many governments and industries. This conference examined recent trends affecting rubber recycling activities as well as the legislative environment and its impacts on future recycling activities. Major rubber recycling markets were reviewed, and emerging product ideas were evaluated. Industry stewardship model and governance models were discussed. The impacts of new advances in tire technology and manufacturing on the rubber recycling industry were also investigated. Issues concerning fixed tipping fees and incentive structures were discussed, and effective management strategies for the recycling of large off-the-road tires were evaluated.

    In electronic manufacturing industry, the applications of an equipment emitting radiofrequency radiation (RFR) are numerous and Increasing. It is known that exposure to RFR at sufficiently high intensity and duration can produce a variety of adverse health effects. This paper presents some results from an extensive studies in the RFR field measurements at frequency range from 100 MHz to 1 GHz. All measurements were performed inside factories located at the Penang Free Trade Zone. In this case, the factories chosen are those that manufacture the electronic components whereby the applications of RFR equipment are likely to be intensive compared to other type of industries. The measurement system used in this study are the portable spectrum-analyzer, the passive log-periodic antenna and a desktop computer for data analysis. Results from this study have indicated that the RFR exposure levels in most factories are in the range of 7.7 x 10 sup -4 - 4.31 x 10 sup -3 Wm sup -2 and 0.01 - 0. 741 Vm sup -1 for power density and electric strength measurement respectively. These ranges are at least 100 times lower compared to the RFR protection guidelines proposed by the American National Standard Institute (ANSI). However, the exposure levels inside the factory are consistently 10 sup -3 - 10 sup -4 higher than the levels caused by natural sources and is about 10 sup 2 - 10 sup 6 higher than the levels measured at a distance of 30 m from a low-power output mobile phone transmitter. In the case of the health effect assessment, no sufficient evidence has been found to indicate the potential consequences resulting from excessive RFR exposure. Nonetheless, many factories surveyed are unaware of the existence of the international guidelines and codes on the safe use of radiofrequency energy even though, some measures are being taken to protect their employees against RFR

    An abstract of the radiation process of polymer materials and the polymer reaction by radiation is explained. Main radiation is 250 keV to 10 MeV of electron rays in the industry. Radiation cross-linked rubber has less the tensile strength than that by sulfur and organic peroxide crosslinking. The main origins of low tensile strength are caused by cut of backbone chain and ozone depend on radiation. Acceleration of crosslinking and short time of radiation are necessary to improve these defects. To accelerate crosslinking, we used crosslinking accelerators, for example, three poly-functional monomers (PFM). The maximum tensile strength of styrene-butadiene rubber (SBR) not added crosslinking accelerators showed 3 MPa at 110 kGy, but SBR added A-TMMT (tetramethylolmethane tetraacrylate) showed 5.5 MPa at 110 kGy. Radiation crosslinking of many kinds of rubber: isoprene (IR), SBR, CR, nitrile rubber (NBR), hydrogenated nitrile rubber (HNBR), butyl rubber (IIR), chlorinated butyl rubber (CIIR), EPM and TPE are explained.

    Full Text Available The manufacturing industry's loss in participation, phenomena called “deindustrialization”, has been observed for the Brazilian economy for a while and seems to have intensified from mid-2000s. However, the literature has not developed a consistent or integrated analysis of this process. We have used a detailed simulation model to identify how macroeconomic factors (such as exchange rate, labor costs, and household consumption have contributed to manufacturing dynamics. Our results indicate that the macroeconomic scenario explains a large portion of the manufacturing industry's participation loss. The rise in households consumption and investment, important factors in this period, were responsible for dampening of the pressures coming from the currency appreciation and the workforce costs, benefiting some industrial sectors, but not avoiding the manufacturings participation loss.

    Mustafa, Zainol; Jamaluddin, Z.

    2017-04-01

    The success of Six Sigma implementation is known to depend on a number of contributing factors. The purpose of this paper is to explore Six Sigma critical success factors (CSFs) in the context of Malaysian manufacturing organizations. Although Six Sigma success factors have been abundantly researched in the global context, in this paper, a maiden attempt is made to identify, through an extensive literature review, the CSFs for Six Sigma implementation followed by their validation using primary data collection from Malaysian manufacturing companies. A total of 33 indicators have thus been compiled through an extensive literature review which then been grouped into 6 contributing factors. These contributing success factors are then validated through an empirical research of selected Malaysian manufacturing companies at various stages of implementation of the Six Sigma process improvement methodology. There has been an overemphasis on the role and commitment of the management in the success of a Six Sigma program. Though it is undoubted, certain other factors also play an equally important role in ensuring that the Six Sigma programs are successful. The factor analysis of CSFs of the Malaysian manufacturing organizations selected in this study demonstrates that the top factor is a composite factor showing combination of the ability of the project teams to use the process management on quality initiative and a training using a proper analysis in problem solving. The CSFs extracted through the factor analysis could provide a basis for manufacturing organizations embarking on the Six Sigma journey to look beyond just management involvement. Thus, one can develop an integrated framework of other factors as outlined and give them appropriate priority and focus.

    Varigos, G A; Dunt, D R

    1981-03-01

    An epidemiological study of occupational dermatitis in a tyre company and a cement company is reported. Ninety-seven percent of 999 tyre workers and 78% of 151 cement workers were screened by an occupational nurse and subsequently assessed by a specialist dermatologist. Prevalence rates of occupational contact dermatitis were 37 per 1000 and 68 per 1000 in the tyre and cement companies, respectively. Maintenance workers and tyre builders - particularly if they were Yugoslav and female - had high prevalence rates amongst tyre workers. Worker's compensation claim rates for the tyre company are similar to U.K. and U.S. rates for this industry. Prevalence rates of 37 per 1000 can be considered as a lower limit for this industry. The high prevalence rates in the cement company are noteworthy and require further study.

    We present improved analyses of rheometric torque measurements as well as (1)H double-quantum (DQ) nuclear magnetic resonance (NMR) buildup data on polymer networks of industrial compounds. This latter DQ NMR analysis allows finding the distribution of an orientation order parameter (Dres) resulting from the noncomplete averaging of proton dipole-dipole couplings within the cross-linked polymer chains. We investigate the influence of the formulation (filler and vulcanization systems) as well as the process (curing temperature) ending to the final polymer network. We show that DQ NMR follows the generation of the polymer network during the vulcanization process from a heterogeneous network to a very homogeneous one. The time variations of microscopic Dres and macroscopic rheometric torques present power-law behaviors above a threshold time scale with characteristic exponents of the percolation theory. We observe also a very good linear correlation between the kinetics of Dres and rheometric data routinely performed in industry. All these observations confirm the description of the polymer network generation as a critical phenomenon. On the basis of all these results, we believe that DQ NMR could become a valuable tool for investigating in situ the cross-linking of industrial polymer networks at the nanometer scale.

    Full Text Available Anti-vibration rubber, because of its superior elasticity, plasticity, waterproof and trapping characteristics, is widely used in the automotive industry, national defense, construction and other fields. The theory and technology of predicting fatigue life is of great significance to improve the durability design and manufacturing of anti-vibration rubber products. According to the characteristics of the anti-vibration rubber products in service, the technical difficulties for analyzing fatigue properties of anti-vibration rubber materials are pointed out. The research progress of the fatigue properties of rubber materials is reviewed from three angles including methods of fatigue crack initiation, fatigue crack propagation and fatigue damage accumulation. It is put forward that some nonlinear characteristics of rubber under fatigue loading, including the Mullins effect, permanent deformation and cyclic stress softening, should be considered in the further study of rubber materials. Meanwhile, it is indicated that the fatigue damage accumulation method based on continuum damage mechanics might be more appropriate to solve fatigue damage and life prediction problems for complex rubber materials and structures under fatigue loading.

    Full Text Available The integration of modern internet technology and manufacturing technology, which has been denominated Industrie 4.0, allows for distributed manufacturing using additive manufacturing on a global scale with the integration of machines and processes. However, distributed manufacturing poses many challenges for standardization, quality control and management of information in different manufacturing sites. This article aims to investigate the formation of networks in distributed manufacturing projects, identifying the stake-holders and types of connections throughout the project. The methodological approach used was longitudinal action research for a distributed manufacturing project with a focus on flexible manufacturing. The central plant was located in Germany and the supplier located in Brazil, with a partnership between the Polytechnic School of the University of São Paulo and the Technical University of Darmstadt, Germany. The design and engineering that spawned the product model was developed in Germany, while the additive manufacturing site, the structure, and machinery was developed in Brazil, forming a development and distributed manufacturing network. The results showed how organized the communication and knowledge sharing was among those involved in the distributed manufacturing project, as well as an understanding of what kind of knowledge is shared among those involved.

    Fiber reinforced polymer (FRP) composites provide a lot of benefits, including strength-to-weight ratio / light weight, superior mechanical properties, low maintenance, prolonged service life, as well as corrosion, fatigue and creep resistance. However, sustainability of the FRP composites have not been studied in detail in terms of long term productions in various industries, such as aerospace, wind energy, automotive and defense. Carbon fibers are relatively expensive because of the energy intensive production systems, and lack of easy production options, which forces many companies to recycle and reuse the FRP composites in the same or different manufacturing industries. This study mainly deals with two important issues, including the disposal of composite wastes generated during the manufacturing of composite parts, and the disposal of the products at the end of their useful life. It is believed that the carbon fibers in the used composites will have still high mechanical strengths to use in different composite manufacturing after its end of life. The major manufacturing costs come from the labor and raw materials, so using the recycled carbon fibers will make sustainable composite productions in other industries. This paper presents the current status and outlook of the FRP composite recycling and re-manufacturing techniques in the same or different industries. A future vision of the FRP composites will be investigated with sustainability point of views. This study will also mention about the sustainability issues in laminate and honeycomb composites, new product design and developments and potential applications in different manufacturing industries.

    2004-01-01

    Who pays for new policies to reduce carbon dioxide and other greenhouse gas emissions in the United States? This paper considers a slice of the question by examining the near-term impact on domestic manufacturing industries of both upstream (economy-wide) and downstream (electric power industry only) carbon mitigation policies. Detailed Census data on the electricity use of four-digit manufacturing industries are combined with input-output information on inter-industry purchases to paint a detailed picture of carbon use, including effects on final demand. Regional information on electricity supply and use by region is also incorporated. A relatively simple model is developed which yields estimates of the relative burdens within the manufacturing sector of alternative carbon policies. Overall, the principal conclusion is that within the manufacturing sector (which by definition excludes coal production and electricity generation), only a small number of industries would bear a disproportionate short-term burden of a carbon tax or similar policy. Not surprisingly, an electricity-only policy affects very different manufacturing industries than an economy-wide carbon tax

    Full Text Available Purpose: The purpose of this study was to examine and obtain empirical evidence of the effects of external and internal environmental factors on the strategy and performance of manufacturing companies. Design/methodology/approach: This study used primary data obtained by distributing questionnaires to 150 respondents of manufacturing companies in Indonesia spreading over six major cities in Java such as Jakarta, Banten, Bandung, Yogyakarta, Semarang and Surabaya. Samples were taken by using the systematic random sampling technique. The technique was used since those major cities had different numbers of manufacturing companies. Subsequently, the feasibility of the model was tested. Several indices of model feasibility would be used to test the model developed in this structural equation model. In case of a sub-optimal model, a model modification was to be performed by adding or removing paths so that the chi-square values would decrease by the values of the index. Findings and Originality/value: Results showed that internal and external environmental factors, through the operating environments and the remote environments of manufacturing industries, jointly affected the companies’ understanding of the condition of the industrial environments to establish strategic goals in order to achieve optimal performance of manufacturing industry. Practical implications: The internal and external environmental factors through the operating and remote environments had effects on the strategy of manufacturing companies in Indonesia. However, both internal and external environments did not affect the performance of manufacturing companies in Indonesia. There was a tendency that manufacturing companies were to observe the occurring macro-economic conditions. Manufacturing industries were faced with the pressures from competition, customers and suppliers that affected companies’ revenue. Performance of manufacturing industries was more influenced by macro

    2017-07-01

    Exposure to low concentrations of heavy metals and metalloids represents a well-documented risk to animal and human health. However, current standards (European Pharmacopeia [EP], United States Pharmacopoeia [USP], International Organization for Standardization [ISO], YBB concerned with rubber closures) only require testing for Zn in pharmaceutical-grade rubber stoppers and then using only pure water as a solvent. We extracted and quantified heavy metals and trace elements from pharmaceutical-grade rubber stoppers under conditions that might occur during the preparation of drugs. Pure water, saline, 10% glucose, 3% acetic acid (w/v), 0.1 mol/L hydrochloric acid, and diethylenetriaminepentaacetic acid (4 mg/mL, 0.4 mg/mL, and 0.04 mg/mL) were used as extraction agents. We quantified the extracted arsenic, lead, antimony, iron, magnesium, aluminum, and zinc using inductively coupled plasma mass spectrometry. The concentration of extracted metals varied depending on the different extraction solutions used and between the different rubber stopper manufacturers. Rubber stoppers are ubiquitously used in the pharmaceutical industry for the storage and preparation of drugs. Extraction of heavy metals during the manufacturing and preparation of drugs represents a significant risk, suggesting a need for industry standards to focus on heavy metal migration from rubber stoppers.

    Rubber crumb obtained from worn out tires has been increasingly used over the last 15-20 years, especially in manufacture of asphalt and cement concrete mixtures. This review pays principal attention to application of the rubber crumb to cement concrete mixtures. Use of the rubber crumb in cement concrete is not as successful as in asphalt concrete mixtures, due to incompatibility problems linked to chemical composition and a significant difference in rigidity between the rubber crumb and concrete mixture aggregates. Different methods are proposed and studied to mitigate the adverse influence and increase the beneficial effects of the rubber crumb when added to cement concrete.

    Full Text Available This paper studies the evolution of the foreign trade specialization in manufacturing sectors of South Africa, Algeria, Nigeria and Egypt. These four countries, the so-called SANE, have recently been viewed as Africa's best chance of producing an economic bloc whose role for Africa might be comparable to that of the BRIC economies of Brazil, Russia, India and China for the world economy. Using data on trade flows since mid-1970s, the results show that the SANE group has experienced few changes in its trade structure, which is still based on low-technology and slow-growth world demand sectors. The degree of persistence in the specialization model is higher in the case of Algeria and Nigeria, where the dependence on products based on natural resources is stronger.

    M97* and M9763 belong to the M97xx series of cellular silicone materials that have been deployed as stress cushions in some of the LLNL systems. Their purpose of these support foams is to distribute the stress between adjacent components, maintain relative positioning of various components, and mitigate the effects of component size variation due to manufacturing and temperature changes. In service these materials are subjected to a continuous compressive strain over long periods of time. In order to ensure their effectiveness, it is important to understand how their mechanical properties change over time. The properties we are primarily concerned about are: compression set, load retention, and stress-strain response (modulus).

    Numerous companies are accepting sustainability as an organizational peremptory. There is, however, little convergence on how organizations become sustainable. The previous study suggests that a paradigm shift is necessary to incorporate more sustainable ways of thinking, while others advocate that sustainability requires only moderate behavioural changes as in attitude. In addition, it is also suggesting that sustainability develops most effectively when a singular view of sustainability is applied throughout the company; others contend that differentiated views of sustainability emerge within the various subcultures of an organization. The aim of this paper is to analyse the aftermath of considering attitudinal parameter into the initial data, portraying the true nature of personality during the survey. The research presented was carried out with employees from various manufacturing companies with different branches of knowledge and attitude. Survey methodology was employed by building a questionnaire combining Likert-type items, Sustainable Development Goals (SDGs), Green Project Management (GPM) P5 Integration and multiple-option items. The results allow identifying the knowledges and attitudes of the employees in Malaysia context, contributing relevant data in regard to future engagement relating to sustainability and attitudinal parameter.

    Planned and projected budget cuts over the next many years will reduce the number of Department of Defense (DoD) personnel and the diversity and quantity of their armaments and systems. Consequently, there is a requirement for the deployment of more effective defense equipment and their more efficient operation. Concomitant with this challenge is an opportunity for innovative technologies that can, at a lower cost, produce new, stronger, more durable materials-and do so with less environmental impact. Radiation processing offers this potential for (a) creating significant cost savings and performance advantages in a broad range of defense materials; (b) destroying and detoxifying dangerous chemicals, ordnance, and rocket propellants; (c) cleaning noxious gaseous effluents; and (d) purifying contaminated water. Radiation technology has the potential to immediately affect defense materials and, in the short and long terms, US industrial international competitiveness

    1996-01-01

    The center has carried out R and D of Radiation Vulcanization Natural Rubber Latex (RVNRL) technology and introduced it to the industries since the inauguration and operation of the latex pilot plant in 1983. After years of experiences and the environmental consideration, n-butylacrylate (n-BA) has replaced CCI, as the sensitizer. Until now the introduction program shows that radiation vulcanized latex is more suitable for home industries than large industries. The obstacle of the program is the marketing of the dipped products. In spite of these problems, the introduction of this technology to the people in some undeveloped area of Java has supported the national program to improve their living standard. The problems of nitrosamine and protein allergic have turn up RVNRL to be the substitute of sulfur vulcanized latex in the future. The cooperation with a national condom manufacturer (PT Mitra Banjaran) has applied RVNRL for condom production in the large scale. Soft condoms with less probability of pinhole are obtained, but the technical problem is stickiness after pilling. Supply to a baby teat and a rubber thread manufacturer offers great advantages by not using any chemicals. In spite of the advantages, the problem of latex viscosity for dipping and the low modulus of elasticity of the threads arise. Through those input CAIR-BATAN is conducting the research and development in improving the crosslinking among the rubber particles that are supposed to be the reason of the stickiness and low modulus of elasticity. This effort is expected to be able to broaden the application of RVNRL, and it will be achieved only by the involvement of rubber chemist, rubber technologist, and radiation chemist

    Full Text Available The production of waste by the tire industry has been a growing problem, indicating the need for its reuse. More than thirty million tires are discharged per year in Brazil, where regulation for the environment states that for each four new tires, five unusable ones must be adequately disposed by manufacturers and importers. Paving consumes an extremely large quantity of materials, which can be the source of rational application of waste and rejected materials. Research shows that tire rubber can be added to asphalt, which increases its durability and improves pavement quality and safety conditions by absorbing the rubber elastic properties, and also be used for architectural applications, among others. This study deals with the addition of rubber fibers from tire crushing in concrete for roadway pavements in order to provide proper indication about the alternative material disposal through an evaluation of the mechanical behavior of the modified concrete. Different concrete mixes were produced, within which, part of fine aggregates were substituted by tire rubber and mechanical experiment tests were performed, which show that, due to great resistance losses, the disposal of this alternative material in concrete should be considered for light traffic pavements, with the addition of rubber ranging up to 10% in mass.

    Full Text Available Abstract Biodiesel has been considered a suitable substitute for petroleum diesel, but their chemical composition differs greatly. For this reason, biodiesel interacts differently than petroleum diesel with various materials, including rubbers. Therefore, the resistance of some elastomers should be thoroughly evaluated, specifically those which are commonly used in automotive industry. Nitrile rubber (NBR is widely used to produce vehicular parts that are constantly in contact with fuels. This paper aimed to assess the resistance of carboxylated nitrile rubber (XNBR with 28% of acrylonitrile content to soybean biodiesel in comparison with non-carboxylated nitrile rubber samples, with high and medium acrylonitrile content (33 and 45%. NBR with medium acrylonitrile content showed little resistance to biodiesel. However, carboxylated nitrile rubber even with low acrylonitrile content had similar performance to NBR with high acrylonitrile content.

    Full Text Available The manufacturing industry is a key sector in many national economies and is involved in creating sustainable economic growth. At the same time, it is a sector sensitive to internal and external impacts that result in fluctuations in the economic cycle, copying its development or even outstripping the development of economic cycles. The main objective of this contribution was to identify the relationship between manufacturing and GDP, which represents the economic cycle in European Union countries. The time series of selected indicators of the manufacturing industry and GDP from the Eurostat database for Q1 2000-Q4 2016 were used for analysis purposes. An analysis of 296 time series with a quarterly periodicity from 22 EU countries (including the United Kingdom was performed. The results of analyses indicate that the processing industry is a sector with significant cyclical behavior. In most countries, production and sales in the manufacturing industry behaved as concurrent indicators, changes in production and sales almost immediately reflected in the growth or decline in GDP. Labor market indicators have been shown to be delayed cyclical indicators. Changes in the economic development of the countries have a strong impact on employment, the remuneration of employees and the number of hours worked in the sector. Strong cyclical industries must be constantly monitored, as negative changes in these sectors will automatically exacerbate the economic cycle recession. The results of our analyses represent a valuable platform for economic policy makers and regional strategic plans.

    Full Text Available Industrialized Building System (IBS is a potential technology to improve productivity of construction industry. Controlled production and minimum generation of construction waste are some of the benefits that can be achieved by replacing conventional construction with IBS. In business, IBS is giving a huge opportunity for manufacturer and supplier to expand their business while contributing to construction development. However, bad strategies will put the company in high risk due to higher initial capital for machines and equipment. Therefore, strategic planning for company’s growth, profit maximization, and enhancement of productivity is undeniable to ensure the success of business in construction industry. This preliminary paper is exploring associated factors that affect Economy of Scale (EOS and their relationships in catalyzing the IBS manufacturer especially precast concrete as the scope of study to continue their business in the construction industry. Thus, a framework of EOS is proposed to assist IBS manufacturers to ensure their company’s growth and stability, competitiveness in term of monopoly or an oligopoly, increasing productivity, leading constant returns to scale, and finally increasing the firm’s efficiency. The refined EOS’s conceptual framework is an important turning point to support the development of decision making tools for IBS manufacturer towards their stability and survival in this highly competitive industry.

    The study computes and analyses the sources of the change of energy intensity of the manufacturing industries in Thailand during the period (1991–2011) using the decomposition method. The Logarithmic Mean Divisia Index is computed and the results show that the energy intensity in the period (1991–2000) increased greatly from the increased energy intensity of each industry. In the more recent period (2000–2011) the energy intensity declined a little. However the decline was mainly from the structural change effect with negligible contribution from decreased energy intensity of each industry. The findings imply the need to balance industrial restructuring policies with efforts to reduce energy intensity for a sustainable economic development. Besides, there is much room for individual industries to improve their energy efficiency. Policies on restructuring energy prices and other non-price related measures should be devised to induce individual industries, particularly the highly energy intensive ones, to reduce their energy intensity. - Highlights: • Decomposing change of energy intensity of Thai manufacturing industries, 1991–2011. • 1991–2000 energy intensity rose due to increased energy intensity of each industry. • 2000–2011 energy intensity declined due mainly to the structural change effect. • Need to balance industrial restructuring policies to reduce energy intensity

    Full Text Available Given the significant requirements for transforming and promoting the process industry, we present the major limitations of current petrochemical enterprises, including limitations in decision-making, production operation, efficiency and security, information integration, and so forth. To promote a vision of the process industry with efficient, green, and smart production, modern information technology should be utilized throughout the entire optimization process for production, management, and marketing. To focus on smart equipment in manufacturing processes, as well as on the adaptive intelligent optimization of the manufacturing process, operating mode, and supply chain management, we put forward several key scientific problems in engineering in a demand-driven and application-oriented manner, namely: ① intelligent sensing and integration of all process information, including production and management information; ② collaborative decision-making in the supply chain, industry chain, and value chain, driven by knowledge; ③ cooperative control and optimization of plant-wide production processes via human-cyber-physical interaction; and ④ life-cycle assessments for safety and environmental footprint monitoring, in addition to tracing analysis and risk control. In order to solve these limitations and core scientific problems, we further present fundamental theories and key technologies for smart and optimal manufacturing in the process industry. Although this paper discusses the process industry in China, the conclusions in this paper can be extended to the process industry around the world.

    2015-05-01

    Nowadays, more and more manufacturing firms have started to implement lean production system in their operations. Lean production viewed as one of the mechanism to maintain the organisation's position and to compete globally. However, many fail to apply the lean concepts successfully in their operations. Based on previous studies, implementation of lean production in the manufacturing industry is more focused on the relationship between Lean and Operational Performance of one dimension only. Therefore, this study attempted to examine the relationship between Lean Production (LP) and Operational Performance in 4 dimensions which are quality, delivery, cost and flexibility. This study employed quantitative study using questionnaires. Data was collected from 50 manufacturing industries. The data was analysed using Statistical Package for Social Science (SPSS) 22.0. This study is hoped to shed new understanding on the concept of Lean Production (LP) in regards of Operational Performance covering the 4 dimensions.

    Over the past decade, significant wind manufacturing capacity has been built in the United States in response to an increasingly large domestic market. Recent U.S. manufacturing production levels exceed anticipated near-term domestic demand for select parts of the supply chain, in part due to policy uncertainty, and this is resulting in some restructuring in the industry. Factor location decisions are influenced by a combination of quantitative and qualitative factors; proximity to end-markets is often a key consideration, especially for manufacturers of large wind turbine components. Technology advancements in the wind sector are continuing, and larger blade designs are being pursued in the market, which may increase U.S.-based manufacturing opportunities.

    Bidis, the most common smoking tobacco product in India, remain largely untaxed and are subject to very few regulations to discourage their use. A major argument against tax increases is the large potential loss of economic activity and employment in the bidi industry from reduced consumption. We used a nationally representative survey of unorganised bidi manufacturing firms (n=2841) in India to estimate the economic contribution of the industry. We find that of the 35 states and union territories of India, the bidi industry operated across 17 states, with over 95% of its production concentrated in 10 states. Bidi manufacturing firms contributed 0.50% of total sales and 0.6% of the gross value added by the manufacturing economy in 2005-2006. The industry employed approximately 3.4 million full-time workers, which comprise about 0.7% of employment in all sectors. A further 0.7 million were part-time workers. Bidi workers were also among the lowest paid employees in India. The industry offered only 0.09% of all compensation provided in the manufacturing sector (organised and unorganised). Considering the relatively small economic footprint of the bidi industry in India, higher excise taxes and regulations on bidis are unlikely to disrupt economic growth at an aggregate level, or lead to mass unemployment and economic hardship among small bidi workers. On average, the economic annual output per bidi worker is about US$143, which is an order of magnitude smaller than the large economic losses from the several hundred thousand deaths due to bidi smoking per year.

    Full Text Available With the rapid development of science and technology, emerging information technologies have significantly changed the daily life of people. In such context, strategic project selection for high-end equipment manufacturing industries faces more and more complexities and uncertainties with the consideration of several complex criteria. For example, a group of experts rather than a single expert should be invited to select strategic project for high-end equipment manufacturing industries and the experts may feel difficulty to express their preferences towards different strategic projects due to their limited cognitive capabilities. In order to handle these complexities and uncertainties, the criteria framework of strategic project selection is firstly constructed based on the characteristics of high-end equipment manufacturing industries and then evidential reasoning (ER approach is introduced in this paper to help experts express their uncertain preferences and aggregate these preferences to generate an appropriate strategic project. A real case of strategic project selection in a high-speed train manufacturing enterprise is investigated to demonstrate the validity of the ER approach in solving strategic project selection problem.

    The most extensive action targeting the adoption of energy efficiency measures in small- and medium-sized manufacturing industries in Sweden over the past 15 years was project Highland. This paper presents an evaluation of the first part of this local industrial energy programme, which shows an adoption rate of more than 40% when both measures that have already been implemented and measures that are planned to be implemented are included. A comparison between this programme and another major ongoing programme for the Swedish energy-intensive industry indicates that the approach used in project Highland aimed at small- and medium-sized industries is an effective way to increase energy efficiency in the Swedish industry. The major barriers to energy efficiency among the firms were related to the low priority of the energy efficiency issue

    Full Text Available A necessidade de regulamentação no sistema agroindustrial (SAG da borracha natural no Brasil é evidente. Desde a metade do século, quando o país passou a importar esse produto, vários esforços governamentais vêm sendo definidos, objetivando o desenvolvimento sustentável do setor da produção agrícola nacional de borracha. No ano de 1997, criou-se uma política de subvenção direta à produção. Dada a estrutura desse SAG, associada à conjuntura do mercado internacional e a uma regulamentação falha do governo federal, começaram a surgir indícios de abuso de poder de mercado pela indústria pneumática instalada no país, principal consumidora do produto. Utilizando o arcabouço teórico da organização industrial, neste artigo se procurou levantar evidências nesse sentido.The need for regulation of Brazil’s natural rubber agro-industrial system (SAG is evident. Since the middle of the 20th century, when the country began importing rubber, many governmental efforts have been made to promote the sustainable development of Brazil’s natural rubber productive sector. In 1997, the Brazilian government created a direct subvention policy to assist rubber producers. Given the structure of Brazil’s SAG, the international rubber market, and imperfect regulation by the Federal Government, it would not be unexpected to find signs that Brazil’s largest natural rubber consumer, the domestic tire industry, has begun to abusively exercise its market power. Using the theoretical structure of Industrial Organization, this paper tries to show evidences of this abuse.

    While the progressive improvement of hygiene situations in the workplaces has taken to a reduction of chemical carcinogens exposure, in recent years in Italy the number of compensated occupational cancer resulting from carcinogens exposures of distant decades, has been increasing. Nevertheless, several experiences suggest that the proportion of occupational cancers unrecognised and not notified, as required by law, still remains important. This contribution concerns some experiences, performed between 2004-2008 by the Local Occupational Health Service (SPSAL) located in a highly industrialised province, on the working sector of rubber, iron and steel industry, the asphalt working and the poultry stock-breeders. This work concerns the following issues: - the evaluation of carcinogens exposure; - technical preventive measures and personal protection; - the level of workers' information and formation and the registration of exposed workers; - the characterization of work-related cancer. The results of the 5 years of activity allow us to underline that, in the most of 49 plants involved in the study, the carcinogens exposure evaluation and the prevention and protection measures were lacking. Information of workers was largely deficient and the registration of exposed workers was absent. A major attention to detect and to evaluate the work-related cancer has allowed us to recognize 50 new cases in the iron-steel industries and 21 new cases in a rubber industry. Although this experience concerns only few occupational fields, it provides the basis to call for a greater commitment of SPSAL addressed to companies and general practitioners to both, the promotion and surveillance of the correct procedures of carcinogens exposure evaluation and his prevention, and the active detection of occupational cancer, still missing.

    Full Text Available Abstract Background Previous reports have indicated an excess of leukaemia in Broome County, New York, particularly in the Town of Union. Surveillance of cancer incidence data indicates that a large proportion of these cases occurred among males ages 65 and older. Shoe and boot manufacturing has been the largest single industry in this area throughout much of the past century. Occupational studies from Europe suggest a link between leukaemia and employment in the shoe and boot manufacturing industry. However, researchers have not found a positive association between leukaemia and employment in the shoe industry among workers in the United States. Methods A matched case-control study was conducted to investigate the association between leukaemia incidence among males 65 and older and employment in the shoe and boot manufacturing industry. Thirty-six cases of leukaemia occurring between 1981–1990; among males age 65 and older; residing in the town of Union met the study case criteria. Death certificates were obtained for each of the cases. These were matched to death certificates of 144 controls on date of death and date of birth +/- 1 year. Death certificates were then examined to determine the employer and occupation of each study subject. Conditional logistic regression was used to determine the risk of leukaemia among those working in the industry. Results The risk of both leukaemia (OR = 1.47; 95% CI 0.70, 3.09 and acute myeloid leukaemia (OR = 1.19; 95% CI 0.33, 4.28 were elevated among those employed in the shoe and boot manufacturing industry, however neither was statistically significant. Conclusion The results, though suggestive of an association between leukaemia and employment in the shoe and boot manufacturing industry, were not statistically conclusive due mainly to limited study power. Several additional limitations may also have prevented the observance of more conclusive findings. Better exposure assessment, information on

    Green Manufacturing (GM) deals with manufacturing practices that reduces or eliminates the adverse environmental impact during any of its phases. It emphasizes the use of processes that do not contaminate the environment or hurt consumers, employees, or other stakeholders. This paper presents the comparative analysis of two Indian industries representing different sectors for validating GM framework. It also highlights the road map of the companies for achieving performance improvement through GM implementation and its impact on organisational performance. The case studies helps in evaluating the companies GM implementation and overall business performance. For this, a developed diagnostic instrument in the form of questionnaire was administered amongst employees in the companies respectively and their responses were analysed. In order to have a better understanding of the impact of GM implementation, the information about overall business performance was obtained over the last 3 years. The diagnostic instrument developed here may be used by manufacturing organisations to prioritise their management efforts to assess and implement GM.

    In the current competitive contexts, it is widely accepted and proved that inter-enterprise collaboration lead in many occasions to better results. The Spanish ceramic industry must improve, dropping its manufacturing costs in order to be able to compete with low cost products coming from Asia. In this sense, this work presents the main results obtained from applying an innovative model, which facilitates the transfer of manufacturing options between two ceramic enterprises that share a common supplier in the scenario where one of them needs more manufacturing capacity than the one booked according to its demand forecast and the another need less. Then, some decisional mechanisms are applied, which output the values for certain parameters in order to augment the benefit of all the three participants. With the application of this model better organisational results both economic and of service level are achieved. (Author)

    Marine product processing is one of the top priority clusters in the national development. Tuna, as a kind of deep ocean fishes, has the highest number of production that significantly increased throughout the years. Indonesia government encourages tuna processing industry, which are mostly dominated by small to medium enterprises, to grow continuously. Nowadays, manufacturers are facing substantial challenges in adopting modern system and technology that will lead a significant improvement through the internet of things (IoT). A smart factory transform integrated manufacturing process, in a high speed processing to respond customer needs. It has some positive impacts, such as increasing productivity, reducing set up time, shortening marketing and other support activities, hence the process is being more flexible and efficient. To implement smart manufacturing system, factories should know the readiness at any level of them, technology capability and strategy appropriateness. This exploratory study aims to identify the criterias, and develop an assessment tools to measure the level towards smart factory.

    The precautionary allergen labelling (PAL) and Voluntary Incidental Trace Allergen Labelling (VITAL ® ) tools were designed by industry to assist consumers with selecting safe foods for consumption. However, a sizeable proportion of food products bear no label, and it is unclear whether these products are free from allergens and therefore safe to consume or have simply not undergone a risk assessment and therefore remain unlabelled for that reason. To assess the prevalence of unlabelled products that have undergone a risk assessment process and to examine the factors influencing industry's uptake of the VITAL ® process. A web-based questionnaire was distributed to Australasian food and grocery manufacturers. One hundred and thirty-seven Australasian manufacturers were contacted, and 59 questionnaires were returned (response rate: 43%). The respondents represented 454 different manufacturing sites. Manufacturers reported that 23% (95% CI 19-28) of products (n=102/434) that had been through the VITAL ® risk assessment process had no PAL statement on the label. 34% (95% CI 30-38), (n=204/600) of products that had undergone another (non-VITAL ® ) risk assessment process had no PAL statement. In examining the factors that influenced industry's uptake of the VITAL ® process, 25 manufacturers reported on factors that influenced the uptake of the VITAL ® process, 76% (CI 95% 55-91) reported that VITAL ® was an effective tool because it was based on science; 52% (CI 95% 31-72) reported that it was too time-consuming and 36% (CI 95% 18-57) identified a concern with it not being endorsed by the government. Currently, we estimate that at least 30% of products may have been through a risk assessment process and yet bear no PAL statement on the label. Permissive labelling could be incorporated onto these products if they have been assessed to be safe for consumption. © 2017 John Wiley & Sons Ltd.

    Effective communication is the most significant ability for project manager and successful project. However, during the management of projects communication, it is very often forgotten, often overlooked or taken for granted. In the management of projects, it is principally necessary to deal with communication during all project lifecycle. Within the project communication, it is very important to define the main methods, tools, support of communication and frequency of communication; these belong to the most important elements of the communication channel which is very often forgotten. Therefore, the main aim of the paper is to analyse the utilisation of the communication channel: communication methods, communication tools, communication frequency and to support project communication in industrial manufacturing enterprises in Slovakia. Based on the research, we can conclude that communication channel is not adequately elaborated in international methodologies and standards of project management as well as in industrial manufacturing enterprises. These facts are very negative, conclusion and it is therefore necessary to deal with the problem.

    2017-05-01

    Full Text Available Because the industrial production requires the application of some transformation procedures on the material resources, so that a clothing product comes out with optimal use value in terms of maximum economic efficiency, one of the main influencial factors is the quality of the products. To make manufacturing processes more efficient, it is necessary to carry out the zero series in order to ensure the quality of the technological processes, as well as to prevent some design deficiencies. Among the main operations undertaken to ensure the quality of the zero series, we mention: creating the conditions for launch, tracking and finalizing the accompanying production documents under similar series production conditions; zero-series producers are usually the same workers who make up the series production line; equipping with the appropriate equipment and providing with necessary devices in order to create the technical conditions for the execution of the zero series; providing technical assistance in relation to manufacturing and control documentation for eliminating the design deficiencies. This paper presents the architecture of the zero series execution in manufacturing processes in the textile garment industry. The information obtained from the zero-series analysis is directed to the technical support, for possible corrections of the patterns according to which the products were manufactured.

    Cooling towers are the heat transfer devices commonly found in industries which are used to extract the high temperature from the coolants and make it reusable in various plants. Basically, the cooling towers has Fills made of PVC sheets stacked together to increase the surface area exposure of the cooling liquid flowing through it. This paper focuses on the study in such a manufacturing plant where fills are being manufactured. The productivity using the current manufacturing method was only 6 to 8 fills per day, where the ideal capacity was of 14 fills per day. In this plant manual labor was employed in the manufacturing process. A change in the process modification designed and implemented will help the industry to increase the productivity to 14. In this paper, initially the simulation study was done using ARENA the simulation package and later the new design was done using CAD Package and validated using Ansys Mechanical APDL. It’s found that, by the implementation of the safe design the productivity can be increased to 196 Units.

    Full Text Available The pharmaceutical industrial has five subsectors: medicines, cosmetics, phytotherapeutics, cleaning products and medical devices. The medicine subsector consists of organisations producing, importing and selling these products. Most studies about this industry have been guided by economic interests without assessing technological aspects of production. This article was aimed at proposing a methodology for assessing and describing the medicine sector according to its technological development by using the manufacturing capability concept. The main information was taken from the Colombian Medicaments and Food Surveillance Institute’s (Instituto Nacional de Vigilancia de Medicamentos y Alimentos - INVIMA databases related to pharmaceutical plant production in Bogotá, including material transformation facilities. This study led to three characteristics being identified for defining the pharmaceutical industry’s manufacturing capability: that related to the pharmacological group to which active pharmaceutical ingredients belong, that linked to specifications regarding medicines’ sterility and that related to the technology required for manufacturing each pharmaceutical product. An analysis of these features has thus been presented and some technologies have been identified which have not been transferred or assimilated by the organisations being studied. It was found that manufacturing capability should be considered as being an indicator of the degree of technological development in these subsectors in Colombia.

    Full Text Available In many modern manufacturing industries, data that characterize the manufacturing process are electronically collected and stored in databases. Due to advances in data collection systems and analysis tools, data mining (DM has widely been applied for quality assessment (QA in manufacturing industries. In DM, the choice of technique to be used in analyzing a dataset and assessing the quality depend on the understanding of the analyst. On the other hand, with the advent of improved and efficient prediction techniques, there is a need for an analyst to know which tool performs better for a particular type of dataset. Although a few review papers have recently been published to discuss DM applications in manufacturing for QA, this paper provides an extensive review to investigate the application of a special DM technique, namely support vector machine (SVM to deal with QA problems. This review provides a comprehensive analysis of the literature from various points of view as DM concepts, data preprocessing, DM applications for each quality task, SVM preliminaries, and application results. Summary tables and figures are also provided besides to the analyses. Finally, conclusions and future research directions are provided.

    Development of integrated mobilization preparedness policies requires planning estimates of available productive capacity during national emergency conditions. Such estimates must be developed in a manner to allow evaluation of current trends in capacity and the consideration of uncertainties in various data inputs and in engineering assumptions. This study developed estimates of emergency operating capacity (EOC) for 446 manufacturing industries at the 4-digit Standard Industrial Classification (SIC) level of aggregation and for 24 key nonmanufacturing sectors. This volume lays out the general concepts and methods used to develop the emergency operating estimates. The historical analysis of capacity extends from 1974 through 1986. Some nonmanufacturing industries are included. In addition to mining and utilities, key industries in transportation, communication, and services were analyzed. Physical capacity and efficiency of production were measured. 3 refs., 2 figs., 12 tabs. (JF)

    The pharmaceutical industry is one of the most regulated industries in Switzerland. Though the concept of good manufacturing practises (GMP) was implemented for chemical production in the early 1990s, the rules and regulations for our industry are in constant evolution. In this article we will highlight the impact of these changes to the industry using three recent guideline up-dates as examples: the implementation of ICH Q3D 'Guideline for elemental impurities', the EU-GMP Guideline Part III Chapter 'Guideline on setting health based exposure limits for use in risk identification in the manufacture of different medicinal products in shared facilities' from 01. June 2015, and the new guidelines to data integrity such as 'PIC/S 041-1 Good Practices for Data Management and Integrity in regulated GMP/GDP environments'. These examples show how scientific approaches help to modernize the control strategies for our products and increase product quality for a better patient safety. The requirements of data integrity regulations are also of interest to industries and universities not working under GxP requirements as they also support the business to improve data quality (traceability) for patent applications, and reduce risk of data falsification.

  11. From technology transfer to local manufacturing: China's emergence in the global wind power industry

    Science.gov (United States)

    Lewis, Joanna Ingram

    This dissertation examines the development of China's large wind turbine industry, including the players, the status of the technology, and the strategies used to develop turbines for the Chinese market. The primary goals of this research project are to identify the models of international technology transfer that have been used among firms in China's wind power industry; examine to what extent these technology transfers have contributed to China's ability to locally manufacture large wind turbine technology; and evaluate China's ability to become a major player in the global wind industry. China is a particularly important place to study the opportunities for and dynamics of clean energy development due to its role in global energy consumption. China is the largest coal consuming and producing nation in the world, and consequently the second largest national emitter of carbon dioxide after only the United States. Energy consumption and carbon emissions are growing rapidly, and China is expected to surpass the US and become the largest energy consuming nation and carbon dioxide emitter in coming decades. The central finding of this dissertation is that even though each firm involved in the large wind turbine manufacturing industry in China has followed a very different pathway of technology procurement for the Chinese market, all of the firms are increasing the utilization of locally-manufactured components, and many are doing so without transferring turbine technology or the associated intellectual property. Only one fully Chinese-owned firm, Goldwind, has succeeded in developing a commercially available large wind turbine for the Chinese market. No Chinese firms or foreign firms are manufacturing turbines in China for export overseas, though many have stated plans to do so. There already exists a possible niche market for the smaller turbines that are currently being made in China, particularly in less developed countries that are looking for less expensive

    A relative risk assessment is presented for the industrial fabrication of several nanomaterials. The production processes for five nanomaterials were selected for this analysis, based on their current or near-term potential for large-scale production and commercialization: single-walled carbon nanotubes, bucky balls (C60), one variety of quantum dots, alumoxane nanoparticles, and nano-titanium dioxide. The assessment focused on the activities surrounding the fabrication of nanomaterials, exclusive of any impacts or risks with the nanomaterials themselves. A representative synthesis method was selected for each nanomaterial based on its potential for scaleup. A list of input materials, output materials, and waste streams for each step of fabrication was developed and entered into a database that included key process characteristics such as temperature and pressure. The physical-chemical properties and quantities of the inventoried materials were used to assess relative risk based on factors such as volatility, carcinogenicity, flammability, toxicity, and persistence. These factors were first used to qualitatively rank risk, then combined using an actuarial protocol developed by the insurance industry for the purpose of calculating insurance premiums for chemical manufacturers. This protocol ranks three categories of risk relative to a 100 point scale (where 100 represents maximum risk): incident risk, normal operations risk, and latent contamination risk. Results from this analysis determined that relative environmental risk from manufacturing each of these five materials was comparatively low in relation to other common industrial manufacturing processes.

    It has been shown that female workers exposed to ethylene glycol ethers (EGEs) in the semiconductor industry have higher risks of spontaneous abortion, subfertility, and menstrual disturbances, and prolonged waiting time to pregnancy. To examine whether EGEs or other chemicals are associated with long menstrual cycles in female workers in the semiconductor manufacturing industry. Cross-sectional questionnaire survey during the annual health examination at a wafer manufacturing company in Taiwan in 1997. A three tiered exposure-assessment strategy was used to analyse the risk. A short menstrual cycle was defined to be a cycle less than 24 days and a long cycle to be more than 35 days. There were 606 valid questionnaires from 473 workers in fabrication jobs and 133 in non-fabrication areas. Long menstrual cycles were associated with workers in fabrication areas compared to those in non-fabrication areas. Using workers in non-fabrication areas as referents, workers in photolithography and diffusion areas had higher risks for long menstrual cycles. Workers exposed to EGEs and isopropanol, and hydrofluoric acid, isopropanol, and phosphorous compounds also showed increased risks of a long menstrual cycle. Exposure to multiple chemicals, including EGEs in photolithography, might be associated with long menstrual cycles, and may play an important role in a prolonged time to pregnancy in the wafer manufacturing industry; however, the prevalence in the design, possible exposure misclassification, and chance should be considered.

    Full Text Available Industries, nowadays, are concerned about energy consumption and ever narrowing rules of emissions by the governments. Therefore, a race to clean; green and less energy consuming manufacturing is going on throughout the world. But in authors’ perspective, the major part of energy exploitation lies in the production of a rejected product. Therefore alongside the use of energy saving processes and machinery, industry should primarily look for rejection reduction. This, apart from energy saving and profitability, will add to the moral responsibility of every person toward nature. Here in this paper, authors describe a case study in which the increased rejection rate of a part of cycle chain assembly is controlled by the application of Six Sigma. Six Sigma, from many years has proved to be an ultimate solution when it comes to the application part in manufacturing industries. It’s very generic and easily applicable methodology has drawn tremendous positive results throughout the world. A financial gain of INR 0.267 million was yielded by implying six-sigma approach. In a move toward energy saving, the money saved by the project was used for green manufacturing to promote energy conservation.

    Full Text Available Economic science has long recognized labour productivity as an important factor of economic growth. In the uncertain conditions of increasingly fierce and complex competition, it becomes one of the key prerequisites for an adequate response to global challenges. The development of labour productivity has to be observed as a multi-dimensional process including numerous interconnected quantitative and qualitative factors, in particular human factors and technological advancement realized through investments in research and development (innovations. The analysis of labour productivity in the manufacturing industry of the selected countries, Germany and China, is performed in the context of an important influential factor – innovations, and interdependently with the economic growth of the selected countries. The research results and the conducted regression analyses indicate a superiority of German labour productivity in the manufacturing industry, which is strongly affected by considerable investments in research and development. However, the technological convergence of China as the upcoming power is increasingly important, which shows that the gap in labour productivity is decreasing, making developed countries face new challenges posed by globalization. The analysis of the interdependence of economic growth (GDP and labour productivity in the manufacturing industry points to a positive link and the conclusion that the elasticity of the GDP to changes in labour productivity is greater in China than in Germany.

    Full Text Available Triggered by the subprime mortgage crisis in the United States (U.S., a financial tsunami has spread rapidly around the globe, from the U.S. to Europe and the rest of the world, causing the world economy to enter a recession. China is no exception, and has suffered a sharp reduction in the growth of its export and manufacturing sectors. In this paper, we attempt to model and analyze the impact of financial crisis on the manufacturing industry in China using data collected from March 2005 to November 2008 by the China Statistical Databases of the National Bureau of Statistics of China. The results indicate that China's manufacturing industry may have to tolerate a significant negative effect caused by the global financial crisis over a period of time, with its gross industrial output value declining continually throughout 2008 and 2009 before reaching a state of equilibrium. The intervention effect is described in this study as temporary but immediate and abrupt. It is found that the ARIMA-Intervention model is more precise at explaining and analyzing the intervention effects of the financial tsunami.

  17. Product manufacturing, quality, and reliability initiatives to maintain a competitive advantage and meet customer expectations in the semiconductor industry

    Capps, Gregory

    Semiconductor products are manufactured and consumed across the world. The semiconductor industry is constantly striving to manufacture products with greater performance, improved efficiency, less energy consumption, smaller feature sizes, thinner gate oxides, and faster speeds. Customers have pushed towards zero defects and require a more reliable, higher quality product than ever before. Manufacturers are required to improve yields, reduce operating costs, and increase revenue to maintain a competitive advantage. Opportunities exist for integrated circuit (IC) customers and manufacturers to work together and independently to reduce costs, eliminate waste, reduce defects, reduce warranty returns, and improve quality. This project focuses on electrical over-stress (EOS) and re-test okay (RTOK), two top failure return mechanisms, which both make great defect reduction opportunities in customer-manufacturer relationship. Proactive continuous improvement initiatives and methodologies are addressed with emphasis on product life cycle, manufacturing processes, test, statistical process control (SPC), industry best practices, customer education, and customer-manufacturer interaction.

  18. Influence of SEBS-MA and SBS compatibilizers on properties and morphology of blends of polystyrene/rubber residue (SBRr from the footwear industry

    Directory of Open Access Journals (Sweden)

    Carlos Bruno Barreto Luna

    Full Text Available Abstract The reuse of rubber waste is very important today, both to reduce the harmful effects on the environment, and to reduce the cost of new material development. Considering that most of the studies reported in literature refer to the reuse of tire waste, this article aims to evaluate the influence of styrene-butadiene-styrene (SBS and styrene-(ethylene-butylene-styrene grafted with maleic anhydride (SEBS-MA compatibilizers on the blend performance of polystyrene (PS/styrene-butadiene rubber residue (SBRr, which come from the footwear industry. The blends were prepared in a co-rotating twin screw extruder and then were molded by injection. They were analyzed by impact and tensile tests, heat deflection temperature (HDT, ductile-brittle transition temperature, dynamic mechanical thermal analysis (DMTA and transmission electron microscopy (TEM. The results evidenced that the use of any of the compatibilizers on the PS/SBRr blend significantly increased the impact strength, while the tensile properties and HDT were lower when compared to the polymer matrix. The ductile-brittle transition temperature remains at approximately 25°C range for all the blends. In general, it has been proved that the SBS was the most effective compatibilization process in the PS/SBRr system. The DMTA test shows the presence of two distinct temperature peaks. The morphologies obtained by TEM of binary and ternary blends were quite different and typical of immiscible blend. The results show a good perspective regarding the use of industrial waste (SBRr, since it may enhance a material that would be discarded.

    With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it. Windustry France is a showcase of the industrial know-how that can be used in the wind power industry both onshore and offshore. It includes local set-ups developed around major fields of activity (e.g. car industry, aeronautics, mechanics, etc.) and industrial port zones (Dunkerque, Rouen/Le Havre, Brest, Nantes Saint-Nazaire, Bordeaux, etc.). Several ministries, regional stakeholders and authorities are also involved (local authorities, Regional directorates for industry, research and the environment (DReal) networks and chambers of commerce and industry), all of which contribute to making Windustry France a collective approach to industrial policy.

    Mirzataheri, M.

    2000-01-01

    The effect of solvent, temperature, time, weight percent of catalyst on the rate and mechanism of cyclization of natural rubber was studied in toluene and xylene solutions having tin tetra chloride catalyst (SnCl 4 ). Iodo metric titration show, with 8% SnCl 4 (based on polymer weight) cyclization occurs, leaving 27.4% of the total unsaturation. Infrared spectra of cyclized natural rubber show decreased absorption intensity at 840 and 780 cm -1 which are characteristic bands of the linear polymer and the appearance of absorption band at 890 cm -1 as cycles were formed. By using this chemical modification, natural rubber is transformed into a resinous thermoplastic, hard, non rubbery cyclized material with much less unsaturation than the original rubber, which could find commercial applications ad adhesives, printing inks, industrial and ship paints

    Belzer, D.B.

    1997-02-01

    To develop integrated policies for mobilization preparedness, planners require estimates and projections of available productive capacity during national emergency conditions. This report develops projections of national emergency operating capacity (EOC) for 458 US manufacturing industries at the 4-digit Standard Industrial Classification (SIC) level. These measures are intended for use in planning models that are designed to predict the demands for detailed industry sectors that would occur under conditions such as a military mobilization or a major national disaster. This report is part of an ongoing series of studies prepared by the Pacific Northwest National Laboratory to support mobilization planning studies of the Federal Emergency Planning Agency/US Department of Defense (FEMA/DOD). Earlier sets of EOC estimates were developed in 1985 and 1991. This study presents estimates of EOC through 2005. As in the 1991 study, projections of capacity were based upon extrapolations of equipment capital stocks. The methodology uses time series regression models based on industry data to obtain a response function of industry capital stock to levels of industrial output. The distributed lag coefficients of these response function are then used with projected outputs to extrapolate the 1994 level of EOC. Projections of industrial outputs were taken from the intermediate-term forecast of the US economy prepared by INFORUM (Interindustry Forecasting Model, University of Maryland) in the spring of 1996.

    Kusano, Shigero

    1992-01-01

    City gas companies in Japan are experiencing an expansion in demand for gas in all manufacturing industries. The reason for this is, first and foremost, external, in that the first and second oil crises and the recent Gulf War have placed the oil market in a state of flux. That is to say, supply and demand in the oil products market is unstable while the stability of city gas, which is the main raw material for LNG, is being highly appraised. Another external reason is related to a subject much in the news recently the world over - the environment. City gas is highly regarded for its minimum environmental impact. Domestic reasons for the expansion include the fact that with the increase in use of city gas in manufacturing industries, the end user is beginning to recognize the various special qualities that city gas possesses. The expansion is also due in part to the unrelenting efforts in sales by the gas producers themselves. This report focuses on the expansion in demand in city gas over the past ten years from the point of view of Tokyo Gas as a producer that has been party to the increased sales of city gas in manufacturing industries for over 10 years giving views on the reasons for the increase. Graphic reports of the actual situation of the industry at meetings such as these are rare and therefore although this is slightly different from the main theme, I would like to proceed with the debate in the hope that this will be beneficial in the expansion of future gas demand in countries all over the world

    In order to make full use of the opportunities while responsibly managing the risks of working with manufactured nanomaterials (MNM), we need to gain insight into the potential level of exposure to MNM in the industry. Therefore, the goal of this study was to obtain an overview of the potential MNM exposure scenarios within relevant industrial sectors, applied exposure controls, and number of workers potentially exposed to MNM in Dutch industrial sectors producing and applying MNM-enabled end products in the Netherlands. A survey was conducted in three phases: (i) identification of MNM-enabled end products; (ii) identification of relevant industrial sectors; and (iii) a tiered telephone survey to estimate actual use of the products among 40 sector organizations/knowledge centres (Tier 1), 350 randomly selected companies (Tier 2), and 110 actively searched companies (Tier 3). The most dominant industrial sectors producing or applying MNM-enabled end products (market penetration >5%) are shoe repair shops, automotive, construction, paint, metal, and textile cleaning industry. In the majority of the companies (76%), potential risks related to working with MNM are not a specific point of interest. The total number of workers potentially exposed to MNM during the production or application of MNM-enabled end products was estimated at approximately 3000 workers in the Netherlands. The results of this study will serve as a basis for in-depth exposure and health surveys that are currently planned in the Netherlands. In addition, the results can be used to identify the most relevant sectors for policy makers and future studies focussing on evaluating the risks of occupational exposure to MNM.

    Full Text Available Failure modes and effects analysis ( F M E A substantially facilitates the efforts of industrial manufacturers in prioritizing failures that require corrective actions to continuously improve product quality. However, the conventional approach fails to provide satisfactory explanation of the aggregate effects of a failure from different perspectives such as technical severity, economic severity, and production capacity in some practical applications. To fulfill the existing gap in the F M E A literature, this paper proposes an extension by considering associated quality cost and the capability of failure detection system as additional determinants to signify the priority level for each failure mode. The quality cost and capacity are considered as key factors for sustainable survival and development of an industrial manufacturer in the fierce competition market these days. The performance of the extended scheme was tested in an empirical case at a non-woven fabrics manufacturer. Analytical results indicate that the proposed approach outperforms the traditional one and remarkably reduces the percentage of defective fabrics from about 2.41% before the trial period to 1.13%,thus significantly reducing wastes and increasing operation efficiency, thereby providing valuable advantages to improve organizational competition power for their sustainable growth.

    Full Text Available Recent advances in modern manufacturing industries have created a great need to track and identify objects and parts by obtaining real-time information. One of the main technologies which has been utilized for this need is the Radio Frequency Identification (RFID system. As a result of adopting this technology to the manufacturing industry environment, RFID Network Planning (RNP has become a challenge. Mainly RNP deals with calculating the number and position of antennas which should be deployed in the RFID network to achieve full coverage of the tags that need to be read. The ultimate goal of this paper is to present and evaluate a way of modelling and optimizing nonlinear RNP problems utilizing artificial intelligence (AI techniques. This effort has led the author to propose a novel AI algorithm, which has been named “hybrid AI optimization technique,” to perform optimization of RNP as a hard learning problem. The proposed algorithm is composed of two different optimization algorithms: Redundant Antenna Elimination (RAE and Ring Probabilistic Logic Neural Networks (RPLNN. The proposed hybrid paradigm has been explored using a flexible manufacturing system (FMS, and results have been compared with Genetic Algorithm (GA that demonstrates the feasibility of the proposed architecture successfully.

    Full Text Available South Africa needs to increase its inward foreign direct investment in order to achieve economic growth. The purpose of this article is to explore which intervention could be launched in the short term to enhance the country's attractiveness for foreign investors. The findings of the literature review demonstrated that incentives, as a determinant of investment, are the short-term intervention with the most significant potential to attract additional foreign direct investment. A comparative study, which provided insight into the incentives that are currently offered to the manufacturing sectors of three countries (South Africa, Malaysia and Singapore, assisted in identifying two additional incentives that the South African government could introduce and three existing incentives that could be amended. The introduction or modification of these incentives could ensure that South Africa has a competitive advantage to attract investment from foreign investors and thereby increase South Africa's inward foreign direct investment in the manufacturing industry.

    Proper management of human and non-human resources in construction and manufacturing projects can give-in considerable savings in time and cost. Construction and Manufacturing industry faces issues in connection with problems related with productivity and the problems are usually connected with performance of employees. The performance of employees is affected by many factors. In this paper a survey was made on respondents who are employed various projects of Saudi Arabia. The researcher developed a theoretical framework from the existing research which was used as a Model to collect and analyze the field data to test the hypothesis. In this research activity three predictors (commitment, job satisfaction and job performance) for determining the change in productivity. The results highlight that commitment and job performance (respectively) are the two predictors which are explaining 37% of variation in the productivity of the companies. The results also show that Job Satisfaction has no role in the prediction of productivity.

    Full Text Available Titanium’s strength-to-density ratio, corrosion resistance and high thermal compatibility makes it the perfect metal for aerospace. Titanium is for instance used for the structural airframe, seat tracks, engine components and landing gear of aircraft. The Boeing 787 that had its test flight in 2009 is one of the latest aircraft designs that incorporates a substantially higher percentage of parts manufactured from titanium due to the weight benefit. Titanium’s extensive use in aerospace applications ensures that the aerospace market is the main driver of titanium metal demand. South Africa is the second largest titanium producer in the world after Australia. The abundance of titanium in South Africa together with the growing demand has led it to be identified as a beneficiation priority in a collaborative government initiative, called Titanium Beneficiation Initiative (TBI. The purpose of this paper is to develop a supply chain model for the anticipated South African titanium component manufacturing industry.

    Understanding the safety climate level is essential to implement a proactive safety program. The objective of this study is to explore the possibility of having a safety climate scale for the Turkish furniture manufacturing industry since there has not been any scale available. The questionnaire recruited 783 subjects. Confirmatory factor analysis (CFA) tested a pre-existing safety scale's fit to the industry. The CFA indicated that the structures of the model present a non-satisfactory fit with the data (χ 2  = 2033.4, df = 314, p ≤ 0.001; root mean square error of approximation = 0.08, normed fit index = 0.65, Tucker-Lewis index = 0.65, comparative fit index = 0.69, parsimony goodness-of-fit index = 0.68). The results suggest that a new scale should be developed and validated to measure the safety climate level in the Turkish furniture manufacturing industry. Due to the hierarchical structure of organizations, future studies should consider a multilevel approach in their exploratory factor analyses while developing a new scale.

  18. The Fuzzy u-Chart for Sustainable Manufacturing in the Vietnam Textile Dyeing Industry

    Directory of Open Access Journals (Sweden)

    Kim-Phung Truong

    2017-07-01

    Full Text Available The inevitability of measurement errors and/or humans of subjectivity in data collection processes make accumulated data imprecise, and are thus called fuzzy data. To adapt to this fuzzy domain in a manufacturing process, a traditional u control chart for monitoring the average number of nonconformities per unit is required to extend. In this paper, we first generalize the u chart, named fuzzy u-chart, whose control limits are built on the basis of resolution identity, which is a well-known fuzzy set theory. Then, an approach to fuzzy-logic reasoning, incorporating the decision-maker’s varying levels of optimism towards the online process, is proposed to categorize the manufacturing conditions. In addition, we further develop a condition-based classification mechanism, where the process conditions can be discriminated into intermittent states between in-control and out-of-control. As anomalous conditions are monitored to some extent, this condition-based classification mechanism can provide the critical information to deliberate the cost of process intervention with respect to the gain of quality improvement. Finally, the proposed fuzzy u-chart is implemented in the Vietnam textile dyeing industry to replace its conventional u-chart. The results demonstrate that the industry can effectively evade unnecessary adjustments to its current processes; thus, the industry can substantially reduce its operational cost and potential loss.

    2010-04-01

    Addressing the risks of nanoparticles requires knowledge about release into the environment and occupational exposure. However, such information currently is not systematically collected; therefore, this risk assessment lacks quantitative data. The goal was to evaluate the current level of nanoparticle usage in Swiss industry as well as health, safety, and environmental measures, and the number of potentially exposed workers. A representative, stratified mail survey was conducted among 1626 clients of the Swiss National Accident Insurance Fund (SUVA), which insures 80,000 manufacturing firms, representing 84% of all Swiss manufacturing companies (947 companies answered the survey for a 58.3% response rate). The extrapolation to all Swiss manufacturing companies results in 1309 workers (95% confidence interval [CI]: 1073 to 1545) potentially exposed to nanoparticles in 586 companies (95% CI: 145 to 1027). This corresponds to 0.08% of workers (95% CI: 0.06% to 0.09%) and to 0.6% of companies (95% CI: 0.2% to 1.1%). The industrial chemistry sector showed the highest percentage of companies using nanoparticles (21.2%). Other important sectors also reported nanoparticles. Personal protection equipment was the predominant protection strategy. Only a few applied specific environmental protection measures. This is the first nationwide representative study on nanoparticle use in the manufacturing sector. The information gained can be used for quantitative risk assessment. It can also help policymakers design strategies to support companies developing a safer use of nanomaterial. Noting the current low use of nanoparticles, there is still time to proactively introduce protective methods. If the predicted "nano-revolution" comes true, now is the time to take action.

  20. The history of the peat manufacturing industry in The Netherlands: Peat moss litter and active carbon

    Directory of Open Access Journals (Sweden)

    M.A.W. Gerding

    2015-11-01

    Full Text Available This article describes the development of three major forms of peat processing by the manufacturing industry in The Netherlands since the last quarter of the 19th century. At a time when peat as a fuel was gradually being replaced by coal, the first form was the peat moss litter industry. Peat moss litter was made from white peat that was ground and sieved in factories which were located mainly in bog areas in the south-east of the province of Drenthe. It served as excellent bedding for horses and cattle. The second form of industrial peat processing was the manufacture, from 1921 onwards, of active carbon made from black peat. The Purit (Norit factory, now part of the Cabot Corporation, is still the only active carbon factory using peat as a raw material. The third form of peat processing was the production of garden peat and potting soil. This is still a widespread activity in peat areas all over the world. The peat moss litter industry thrived from the 1880s until shortly after the First World War. The arrival of the horse-drawn tram in all of the major cities of Europe created a great demand for animal bedding to be used in the vast stables of the tramway companies. Peat moss litter was cleaner, healthier and easier to handle than straw. There was similar demand from the armies, which used millions of horses during the First World War. Owing to the development of motorised vehicles, the peat market collapsed after the war and this plunged the industry into a prolonged crisis which was not overcome until peat was found to be a suitable growing medium for horticulture in the 1950s. Living and working conditions in peatlands were harsh, earnings irregular and labourers’ rights limited. The peat manufacturing industry was the first to introduce collective labour agreements, medical benefits and pension plans. Nonetheless massive unemployment, poverty and the necessity to migrate to other parts of the country were clear signs that the era of

    Full Text Available After the Sanlu tainted milk powder crisis in China in 2008, the entire powdered milk manufacturing industry, and in many ways the food industry as a whole, faced a crisis of reputation and consumer confidence. Through a study of the organisation and public relationships of dairy companies, the crisis communication strategies they used, and how they cultivated relationships, this paper explores how companies within the milk industry rebuilt their reputations to a point where customers and other key elements of the public once again felt confident about their products. This study explores the organisation­-public relationships (OPRs cultivation strategies of the dairy companies and the communication strategies they used to rebuild the industry's reputation after the Sanlu crisis. The author interviewed dairy company personnel and consumers in China (N=18 and conducted secondary document research. The communication strategies that dairy companies used to maintain their relationship with the public are analysed. This study develops the theory of relationship management and provides suggestions for other companies to utilise should they face an industry crisis in the future. The cultivation strategies the dairy companies use to maintain their relationship with the public is hard to separate from communication strategy employed after the crisis.

    Full Text Available With the intensification of international competition, there are many international technological collaborations in the integrated circuit manufacturing (ICM industry. The importance of improving the level of international technological collaboration is becoming more and more prominent. Therefore, it is vital for a country, a region, or an institution to understand the international technological collaboration characteristics of the ICM industry and, thus, to know how to enhance its own international technological collaboration. This paper depicts the international technological collaboration characteristics of the ICM industry based on patent analysis. Four aspects, which include collaboration patterns, collaboration networks, collaboration institutions, and collaboration impacts, are analyzed by utilizing patent association analysis and social network analysis. The findings include the following: first, in regard to international technological collaboration, the USA has the highest level, while Germany has great potential for future development; second, Asia and Europe have already formed clusters, respectively, in the cooperative network; last, but not least, research institutions, colleges, and universities should also actively participate in international collaboration. In general, this study provides an objective reference for policy making, competitiveness, and sustainability in the ICM industry. The framework presented in this paper could be applied to examine other industrial international technological collaborations.

  8. Understanding industrial energy use: Physical energy intensity changes in Indian manufacturing sector

    International Nuclear Information System (INIS)

    Sudhakara Reddy, B.; Kumar Ray, Binay

    2011-01-01

    This study develops and examines physical energy intensity indicators in five industrial sub-sectors-iron and steel, aluminum, textiles, paper, and cement-and investigates mitigation options for energy related CO 2 emissions (during 1991-2005). Decomposition analysis has been employed to separate the structural effect (share of different products in the sector) from pure intensity effect (efficiency increase through technical improvement) for each industry. The results show that the combined effect (considering both structural and intensity effects together) on both iron and steel and paper and pulp industries is negative while it is positive for aluminum and textiles. The intensity effect for all the industries, barring textiles, is negative showing improvement in energy efficiency; iron and steel in particular, has seen a decrease of 134 PJ in energy consumption owing to improvements in efficiency. However, energy intensity in textiles has risen by 47 PJ due to increased mechanization. Structural effect is positive in aluminum and iron and steel industries indicating a movement towards higher energy-intensive products. In the case of aluminum, positive structural effect dominates over negative intensive effect whereas negative intensive effect dominates iron and steel industry. The paper helps in designing policies for improving productivity and reduce energy consumption in India's manufacturing sector. - Highlights: → The study develops physical energy intensity indicators in industrial sub-sectors of India. → It identifies technological and other options for reduction in energy consumption. → The study quantifies savings in energy as well as CO 2 emissions. → The indicators are useful in examining structural changes.

    Directory of Open Access Journals (Sweden)

    Davies, Edward

    2016-11-01

    Full Text Available The increasing demand for water and energy in South Africa, and the capacity constraints and restrictions of both resources, have led to a rapid increase in their cost. The manufacturing industry remains South Africa’s third-largest consumer of water and second- largest consumer of national energy. The improvement of water and energy efficiency is becoming an increasingly important theme for both organisational success and national economic sustainability. This paper presents the ‘lean based water and energy stream mapping framework’ developed for the manufacturing industry, with the specific objective of decreasing its water and energy intensity. As with the traditional value stream mapping tool, the water and energy stream mapping focuses on eliminating water- and energy-specific wastes within a process. Water and energy waste categories that will be used in conjunction with the framework will also be discussed. The key objective of this paper is to detail the process of creating the water and energy stream mapping, and the statistical forecasting methodology used to develop the baseline water and energy demand data. The outcome of the implementation of the framework is the future state water and energy stream mapping, which is effectively a blueprint for increased water and energy efficiency within a studied process.

    Nowadays, soft factors have become the key factors of success in quality improvement of an organisation. Many organisations have neglected the importance of soft factors, this may influence the organisational performance. Hence, the purpose of this research is to examine the impact of soft factors on quality improvement in manufacturing industries. Six hypotheses were examined while considering six dimensions of soft factors including management commitment, customer focus, supplier relationship, employee involvement, training and education, and reward and recognition that have a positive impact on quality improvement. In this study, eighty one managers from the quality department were randomly selected in the manufacturing industry in Batu Pahat, Johor. The questionnaires were distributed to them. The researcher analysed the quantitatively collected data using descriptive analysis and correlation analysis. The findings of this study revealed that all soft factors are correlated to the quality improvement in an organisation with a high significant value but the regression analysis shows that the supplier relationship and employee involvement has more significant impact on quality improvement as compared to other soft factors which contributes of this study.

The length of the textile process and the variety of its technical processes lead to the coexistence of different sub-sectors in regards to their business structure and integration. The textile industry is developing expert systems applications to increase production, improve quality and reduce costs. The analysis of textile designs or structures includes the use of mathematical models to simulate the behavior of the textile structures (yarns, fabrics and knitting. The Finite Element Method (FEM has largely facilitated the prediction of the behavior of that textile structure under mechanical loads. For classification problems Artificial Neural Networks (ANNs haveproved to be a very effective tool as a quick and accurate solution. The Case-Based Reasoning (CBR method proposed in this study complements the results of the finite element simulation, mathematical modeling and neural networks methods.

    Iran imports nearly 55,000 tons of Chrysotile asbestos per year and asbestos cement (AC) plants contribute nearly 94% of the total national usage. In the present study, airborne asbestos concentrations during AC sheet manufacturing were measured. The fiber type and its chemical composition were also evaluated by scanning electron microscopy (SEM), with energy-dispersive X-ray analysis. Airborne total fiber concentrations of 45 personal samples were analyzed by phase contrast microscopy. The results have highlighted that 15.5% of samples exceed the threshold limit value (TLV) established the American Conference of Governmental Industrial Hygienists, which is 0.1 fiber per milliliter (f/ml). Personal monitoring of asbestos fiber levels indicated a ranged from 0.02 ± 0.01 to 0.16 ± 0.03 f/ml. The geometrical mean was 0.05 ± 1.36 f/ml, which is considerably lower than the TLV. SEM data demonstrate that the fibrous particles consisted, approximately, of Chrysotile (55.89%) and amphiboles (44.11%). We conclude that the industrial consumption of imported Chrysotile asbestos is responsible for the high airborne amphibole asbestos levels in the AC sheet industry. More research is needed to improve characterization of occupational exposures by fiber size and concentration in a variety of industries.

    Full Text Available Over the last three decades, new economic theories explode the factors depending on space and spatial characteristics. In this process, it is developed the theories on social-cultural aspects and spatial characteristics of regions instead of traditional economic theories. These theories have been main strategy for economic development and growth. Economic development has not been considered independently from space by these theories and economic performance of a region was emphasized importance of economic actors, institutional and economic infrastructure as well as geographic features. Geography or spatial features contribute to increase not only skilled workforce, knowledge spillover and distribution but also social relations and interaction. In other words, the social-cultural and humanity factors relating with spatial and geography are major factors affecting on the development and also growing of economic activities. Especially, while industrialization as engine of regional development has been benefiting from the advantages offered by spatial features, clustering of economic activities and relationships among actors are shaped according to socio-cultural and human factors revealed spatial features. In this context, clustering of economic activities has been one of the new areas of interest in the theory of economic geography. Therefore, clustering of economic activities and human-social-spatial resources has been emphasized to play a major role in growth and development of regions by essays of the new economic geography. In that context, the aim of this paper is to determine the effects of human and social capital in the spatial agglomeration of economic activities in case of Konya-Turkey. In this study, the agglomeration tendencies for manufacturing industry in Konya, which have major potentials in terms of human and social capital and manufacturing industry potential, is analysed comparatively depending on secondary resources and using

    2018-06-01

    Full Text Available This study investigated the implications of large-scale land concessions in the Red River Delta, Vietnam, and Northeast Cambodia with regard to urban and agricultural frontiers, agrarian transitions, migration, and places from which the migrant workers originated. Field interviews conducted near large-scale land concessions for industrial estates in the Red River Delta and rubber plantations in Northeast Cambodia suggest that these radically different concessions are paradoxically leading to similar reconfigurations of livelihoods, labor patterns, and landscapes despite basic differences in these forms of land use. Both the Red River Delta and Northeast Cambodia are frontier environments undergoing extensive agrarian change with migration to work in the large-scale land concessions leading to a shortage of farm labor that anticipates changes in farming practices and farm livelihoods. These population movements will lead to further land-use changes as governments invest in the infrastructure and services needed to support increased population density in the receiving areas. In addition, labor migrations associated with these investments affect land-use practices both at the site of the concession and the places from where the migrants originate.

    International Nuclear Information System (INIS)

    2000-02-01

    This report summarizes and analyses the work that have been carried out by the Transportation Equipment Manufacturing Sector (TEMS) Working Group of the National Climate Change Industry Table over the last 14 months, and presents the Group's view of appropriate policies for greenhouse gas emission reduction in Canada. To develop its approach, the Working Group conducted five separate studies which are included in this report as annexes. Annex A is a Foundation Paper, which provides an overview of the sector's performance vis-a-vis energy use and greenhouse gas production. Annex B analyzes the competitive position of the industry by reviewing growth trends in each of the industry sub-sectors and the key factors in maintaining and enhancing the sector's international competitive position. Annex C is a technology assessment. It provides an overview of the uptake of energy saving technology in the sector. Annex D provides a facility level analysis focusing on energy use in the automotive parts manufacturing sector. Annex E is a review of American policies on climate change, summarizing the approach currently being taken towards greenhouse gas emission reduction in the United States. Some of the key findings of this report are: (1) business-as-usual emissions will greatly exceed the implicit Kyoto target of six per cent reduction from 1990 levels, (2) relatively few opportunities exist for major emissions reductions through the use of existing technology, (3) sector-specific policies appear to be ill-advised, but cross-cutting policies provide good opportunities for the transportation equipment manufacturing sector to do its part in helping Canada meeting its Kyoto commitment. The report recommends investigation of barriers to adoption of new technologies and examination of market imperfections, promotion of cogeneration where it makes economic sense, and consideration of the use of flexible instruments such as carbon taxes and tradable emission permits. Overall, the

    Calls for emergency right-to-know in the 1980s, and, in the 1990s, risk management planning, motivated U.S. chemical manufacturing and refining industries to operationalize a three-pronged approach to risk minimization and communication: reflective management to increase legitimacy, operational safety programs to raise trust, and community engagement designed to facilitate citizens' emergency response efficacy. To assess these management, operational, and communication initiatives, communities (often through Local Emergency Planning Committees) monitored the impact of such programs. In 2012, the fourth phase of a quasi-longitudinal study was conducted to assess the effectiveness of operational change and community outreach in one bellwether community. This study focuses on legitimacy, trust, and response efficacy to suggest that an industry can earn legitimacy credits by raising its safety and environmental impact standards, by building trust via that change, and by communicating emergency response messages to near residents to raise their response efficacy. As part of its campaign to demonstrate its concern for community safety through research, planning, and implementation of safe operations and viable emergency response systems, this industry uses a simple narrative of risk/emergency response-shelter-in-place-communicated by a spokes-character: Wally Wise Guy. © 2015 Society for Risk Analysis.

    Full Text Available CPS is potential application in various fields, such as medical, healthcare, energy, transportation, and defense, as well as Industry 4.0 in Germany. Although studies on the equipment aging and prediction of problem have been done by combining CPS with Industry 4.0, such studies were based on small numbers and majority of the papers focused primarily on CPS methodology. Therefore, it is necessary to study active self-protection to enable self-management functions, such as self-healing by applying CPS in shop-floor. In this paper, we have proposed modeling of shop-floor and a dynamic reconfigurable CPS scheme that can predict the occurrence of anomalies and self-protection in the model. For this purpose, SVM was used as a machine learning technology and it was possible to restrain overloading in manufacturing process. In addition, we design CPS framework based on machine learning for Industry 4.0, simulate it, and perform. Simulation results show the simulation model autonomously detects the abnormal situation and it is dynamically reconfigured through self-healing.

    Universally musculoskeletal disorders are among the leading causes of low productivity in today's work environment. The situation is reportedly even worse in developing countries with appalling working conditions in many industries. In addition, there is often an acute lack of awareness of ergonomics issues, education and training programmes, and certification within developing countries. Numerous studies internationally have highlighted musculoskeletal risk factors associated with the textile industry and garment-making jobs because of highly repetitive work in awkward work postures. The objective of this study was to identify and describe possible ergonomics deficiencies in the workstation of sewing machine operators in a textile industry in Botswana as well as their perception of workload and bodily discomfort. This study focused on one textile manufacturing factory in Botswana where 157 female sewing machine operators were recruited as participants. A modified Corlett and Bishop body map questionnaire and the NASA TLX were administered and relevant anthropometric and workplace layout measurements were collected. The results of the study revealed a high prevalence of musculoskeletal disorders. Back, neck and shoulder discomfort are highly prevalent among these sewing machine operators. This study proposes intervention strategies including the re-design of the workstations and seating and the provision of training in basic ergonomics principles for improving the work-life of these operators and provides a base for further research on the prevalence of musculoskeletal disorders among sewing machine operators in developing countries.

    Enhancing food safety in developing countries, such as Indonesia, poses more challenges, especially those of the small- and medium-scale. Various food safety systems are available and readily implemented in the food industry. However, to ensure the effectiveness of such systems, pre-requisite programs should be applied prior to the implementation of food safety system. One of the most acknowledged pre-requisite program is Good Manufacturing Practices (GMP). The aim of this study is to assess the GMP compliance of some small-scale food companies in East Java. Three types of traditional food product were selected, include tempe chips, palm sugar, and instant herbal drink. A survey involving three companies for each type of traditional food was conducted. Data was obtained through observation and assessment based on tabulated criteria in GMP criteria. In essential, the result revealed the compliment level of the food companies being surveyed. There was different level of compliment between each type of the food industry, where the palm sugar industry had the lowest level of compliment compared to the other two. This difference is due to the food safety awareness, social and cultural influences, and also knowledge on food safety and hygiene practice.

    The high energy radiation on butyl rubber compounds causes a number of chemical reactions that occur after initial ionization and excitation events. These reactions lead to changes in molecular mass of the polymer through scission and crosslinking of the molecules, being able to affect the physical and mechanical properties. Butyl rubber has excellent mechanical properties and oxidation resistance as well as low gas and water vapor permeability. Due to all these properties butyl rubber is widely used industrially and particularly in tires manufacturing. In accordance with various authors, the major effect of high energy, such as gamma rays in butyl rubber, is the yielding of free-radicals along with changes in mechanical properties. There were evaluated effects imparted from high energy radiation on mechanical properties of butyl rubber compounds, non-irradiated and irradiated with 25 kGy, 50 kGy, 150 kGy and 200 kGy. It was also observed a sharp reducing in stress rupture and elongation at break for doses higher than 50 kGy, pointing toward changes in polymeric chain along build-up of free radicals and consequent degradation.

    Full Text Available The correlation between growth in export and economic growth, which is called “Export-led Growth Hypothesis” in the literature, is still a current issue in both the theoretical and empirical literature. In the present study, the effect of different classifications of export and import on economic growth in 22 developing countries in the 1998–2006 period was tested based on two models, via panel data analysis. According to the results of the first model, the analysis of which included variables such as high and low-tech manufacturing industry exports, investment and population, it was found that only two variables, high-tech manufacturing industry export and investment, have a positive and significant effect on growth. In addition to the first model which included the analysis of all variables, the second model investigated the effect of high and low-tech manufacturing industry imports on growth. The findings revealed that only high-tech manufacturing industry export, investment and low-tech manufacturing industry import have a positive and significant effect on growth.

  13. Software defined networking firewall for industry 4.0 manufacturing systems

    Full Text Available Purpose: In order to leverage automation control data, Industry 4.0 manufacturing systems require industrial devices to be connected to the network. Potentially, this can increase the risk of cyberattacks, which can compromise connected industrial devices to acquire production data or gain control over the production process. Search engines such as Sentient Hyper-Optimized Data Access Network (SHODAN can be perverted by attackers to acquire network information that can be later used for intrusion. To prevent this, cybersecurity standards propose network architectures divided into several networks segments based on system functionalities. In this architecture, Firewalls limit the exposure of industrial control devices in order to minimize security risks. This paper presents a novel Software Defined Networking (SDN Firewall that automatically applies this standard architecture without compromising network flexibility.   Design/methodology/approach: The proposed SDN Firewall changes filtering rules in order to implement the different network segments according to application level access control policies. The Firewall applies two filtering techniques described in this paper: temporal filtering and spatial filtering, so that only applications in a white list can connect to industrial control devices. Network administrators need only to configure this application-oriented white lists to comply with security standards for ICS. This simplifies to a great extent network management tasks. Authors have developed a prototype implementation based on the OPC UA Standard and conducted security tests in order to test the viability of the proposal. Findings: Network segmentation and segregation are effective counter-measures against network scanning attacks. The proposed SDN Firewall effectively configures a flat network into virtual LAN segments according to security standard guidelines. Research limitations/implications: The prototype implementation still

    2017-07-01

    Full Text Available Energy conservation is relevant to increasing efficiency in energy projects, by saving energy, by its’ rational use or by switching to other forms of energy. The goal is to secure energy supply on short and long term, while increasing efficiency. These are enforced by evaluating the companies’ energy status, by monitoring and adjusting energy consumption and organising a coherent energy management. The manufacturing process is described, starting from the state and properties of the raw material and ending with the glass drying technological processes involved. Raw materials are selected considering technological and economic criteria. Manufacturing is treated as a two-stage process, consisting of the logistic, preparation aspect of unloading, transporting, storing materials and the manufacturing process itself, by which the glass is sifted, shredded, deferrized and dried. The interest of analyzing the latter is justified by the fact that it has a big impact on the final energy consumption values, hence, in order to improve the general performance, the driers’ energy losses are to be reduced. Technological, energy and management solutions are stated to meet this problem. In the present paper, the emphasis is on the energy perspective of enhancing the overall efficiency. The case study stresses the effects of heat recovery over the efficiency of a glass drier. Audits are conducted, both before and after its’ implementation, to punctually observe the balance between the entering and exiting heat in the drying process. The reduction in fuel consumption and the increase in thermal performance and fuel usage performances reveal the importance of using all available exiting heat from processes. Technical faults, either in exploitation or in management, lead to additional expenses. Improving them is in congruence with the energy conservation concept and is in accordance with the Energy Efficiency Improvement Program for industrial facilities.

    This study quantified greenhouse gas (GHG) emissions from the Pakistan Tobacco Company (PTC) production using a life cycle approach. The PTC production chain comprises of two phases: agricultural activities (Phase I) and industrial activities (Phase II). Data related to agricultural and industrial activities of PTC production chain were collected through questionnaire survey from tobacco growers and records from PTC manufacturing units. The results showed that total GHG emissions from PTC production chain were 44,965, 42,875, and 43,839 tCO 2 e respectively in 2009, 2010, and 2011. Among the agricultural activities, firewood burning for tobacco curing accounted for about 3117, 3565, and 3264 tCO 2 e, fertilizer application accounted for 754, 3251, and 4761 tCO 2 e in 2009, 2010, and 2011, respectively. Among the industrial activities, fossil fuels consumption in stationary sources accounted for 15,582, 12,733, and 13,203 tCO 2 e, fossil fuels used in mobile sources contributed to 2693, 3038, and 3260 tCO 2 e, and purchased electricity consumed resulted in 15,177, 13,556, and 11,380 tCO 2 e in 2009, 2010, and 2011, respectively. The GHG emissions related to the transportation of raw materials and processed tobacco amounted to 6800, 6301, and 7317 respectively in 2009, 2010, and 2011. GHG emissions from energy use in the industrial activities constituted the largest emissions (i.e., over 80%) of GHG emissions as PTC relies on fossil fuels and fossil fuel based electrical power in industrial processes. The total emissions of carbon footprint (CFP) from PTC production were 0.647 tCO 2 e per million cigarettes produced in 2009, 0.675 tCO 2 e per million cigarettes in 2010 and 0.59 tCO 2 e per million cigarettes in 2011. Potential strategies for GHG emissions reductions for PTC production chain include energy efficiency, reducing reliance on fossil fuels in non-mobile sources, adoption of renewable fuels including solar energy, energy from crop residues, and promotion of

    This paper attempts to investigate the drivers and barriers that large-scale Greek manufacturing industries experience in adopting electronic invoices (e-invoices), based on three case studies with organizations having international presence in many countries. The study focuses on the drivers that may affect the increase of the adoption and use of e-invoicing, including the customers demand for e-invoices, and sufficient know-how and adoption of e-invoicing in organizations. In addition, the study reveals important barriers that prevent the expansion of e-invoicing, such as suppliers’ reluctance to implement e-invoicing, and IT infrastructures incompatibilities. Other issues examined by this study include the observed benefits from e-invoicing implementation, and the financial priorities of the organizations assumed to be supported by e-invoicing

    Full Text Available Certain authors describe some professions in the healthcare industry as the more susceptible ones to developing a burnout syndrome, while others suggest psychosocial aspects of the workplace as the primary cause in its creation, but not the aspects of the job itself. The main objective of the research was to investigate which specific factors were associated with the burnout syndrome among professionals working in pharmaceutical manufacturing industry and marketing. The study was conducted in June of 2016 as a cross-sectional study and it included 75 university educated professionals from the area of pharmaceutical industry and marketing employed in several local as well as internationally renowned pharmaceutical companies located in Belgrade. The participants were surveyed anonymously. The instruments used in the study were: a general socio-demographic questionnaire, an assertiveness self-evaluation questionnaire and the Maslach Burnout Inventory. An analysis of the responses in the burnout syndrome self-evaluation questionnaires showed that the highest level of burnout was expressed through reduced personal accomplishment (53%. The average assertiveness scores were the lowest in the individuals who demonstrated the highest level of emotional exhaustion (p=0.003, depersonalization (p=0.004, and the highest inefficiency on professional accomplishment scale (p=0.001. A statistically significant difference was observed in frequency and extent of emotional exhaustion with respect to respondents' gender (x2=10.779; p<0.05, as well as the line of business (x2=6.493; p<0.05. Levels of depersonalization are influenced by: line of work (x2=5.393; p<0.05, age (p=0.004, total years of service (p=0.009 and years of service in the profession (p=0.006. A sense of reduced personal accomplishment is influenced by a respondents' profession (x2=10.922; p<0.05 and line of business (x2=7.283; p<0.05.

    Full Text Available Background & objective: Perceived social support in the personnel of any organization is an important psychological factor that affects the efficiency of the workforce and exerts direct and positive effects on the their quality of life. The present study was conducted to investgiate the level of perceived social support in the personnel of a manufacturing industry in Urmia and to determine its relationship with certain demographic variables. Methods: The present descriptive study was conducted on 156 personnel of a manufacturing industry in Urmia. Data collection was conducted using the Perceived Social Support Questionnaire. The results obtained were then analyzed using descriptive and analytical statistics, including the chi-squared test and the one-way analysis of variance. Results: The mean value of perceived social support from coworkers (3.36±0.72 was higher than the mean value of perceived social support from managers (2.99±0.65. Perceived social support from coworkers and managers was found to have a statistically significant relashionship with age, work experience and type of employment contract (P-value<0.05. Conclusion: Given that perceived social support from coworkers and managers fell in the medium range in the present study, managers should make efforts to foster a greater social support in the workplace for their personnel and to create better relationships with them in the attempt to improve their performance in different domains. Due to the greater need of the less-experienced personnel for social support, managers are recommended to show their support through devising bonus schemes, providing emotional support and establishing a better relationship with their personnel.

    The spanish 'Real Decatur 783/2001', published as result of the adaptation of the European Council directive 96/29/EURATOM (B.S.S. directive), regulates in Spain the use of natural radioactive substances. This decree establishes the need to study and control those activities in which significant increases of the exposure of workers or members of the public could take place. One of these natural radioactive substances are zirconium minerals. They are widely employed in some industrial activities, such as the production of zirconia and zirconium chemicals, glazed ceramic products manufacture, refractories, foundry sands (including investment casting) and zirconium mineral manufacturing. Its major end uses are fine ceramics where it acts as an opacifier in glazes and enamels and also as an additive in special glass (i.e. TV glass). This paper provides a description of a measurement campaign carried out to estimate the risk of occupational exposure to natural radioactivity in the zirconium mineral manufacturing industries. Zirconium raw sands have generally a granular size of 100 to 200 μm, which may be reduced to around 2 μm for use in ceramics and paint applications by milling to flour. These sands contain varying concentrations of natural radionuclides: 232 Th, 235 U, and mostly 238 U, together with their progenies. The first part of the study is to identify situations and areas where worker s are exposed to radiation. Five pathways of exposure were found: inhalation of dust, ingestion of dust, inhalation of radon, skin contamination and external irradiation. Samples from raw materials and from the environment at the work areas are performed; both where the zircon sands are unloaded and stored and at the milling area. Secondly, collected samples are analysed to evaluate activities on those natural radionuclides. Gamma spectrometry analysis is performed for the whole of the samples. For this purpose, a Ge-HP detector (high purity Ge detectors) is used. Dust samples

    Full Text Available Benchmarking is a method used to measure the products, services and processes in comparison to an entity recognized as a leader in terms of performance of its operations. Used in the years 1970-1980 in the strategic management of the company currently has proven to be increasingly useful in many areas, including in international analysis models. In the European Union benchmarking indicators are used especially in the digital economy and as perspective indicators for 2011-2015 (Eurostat, Database. In the introduction we present and define forms of benchmarking, as well as a number of specific terms, which contribute to a better understanding of the content of this scientific work. Time series are used to highlight advances in labor productivity in EU countries, and the analysis is particularized for two countries: Romania and Germany. Quantitative data were collected from the source Eurostat website. A comprehensive indicator at macroeconomic level is resource productivity, representing GDP in relation with domestic consumption of material (DCM. DCM measures the amount of materials used directly by an economy. It is presented in tabular form for all European Union countries and Switzerland, as evolving over a period of eight years. Benchmarking method is used to highlight some differences (gaps between EU countries regarding productivity and particularly the one between Germany and Romania is highlighted, concerning the performance of manufacturing industries. It is expected that this gap will diminish. The gap was highlighted by relevant graphics and interpretations. The second part of the paper focuses on comparative analysis of factors productivity using the production function. We analyze labor and capital productivity and other factors that determine the level of production. For highlighting the contribution of the labour factor we used the number of hours worked, considering that it reflects the analyzed phenomenon more realistically. For

    2014-10-01

    Full Text Available This paper examines impact of employment agglomeration in fifteen U.S. manufacturing industries on their innovation activities measured by patent count. A count data model is employed in regressing patent count on employment agglomeration measures, measure of scale, and some control variables. Measures of employment agglomeration and market concentration are found to have negative impacts on innovation in U.S. manufacturing industries. Two agglomeration proxies -Gini index and Ellison-Glaeser index have a negative influence on U.S. patented innovation for the study period. This result implies that the external benefit of spatial agglomeration of similar firms has waned down. The impact of market concentration is also found to be a negative factor for innovation. This result implies that firms with larger plant size are less innovative than those with smaller plant size. Impact of ‘share of workers with post graduate degrees’ on innovation was found to be a positive but statistically not significant factor for innovation. The ‘goods pooling’ determinant displayed negative influence on innovation. These results are mostly consistent across fifteen manufacturing subsectors. Rising energy cost is found to be one of the most significant deterrents of innovation whereas, ethnic diversity is found to be a significant facilitator of it. Results of this research lend support in favor of regional economic development policies that promote coagglomeration of various interdependent and complementary industries and small scale industries, and supports ethnic diversity to spur innovation in U.S. manufacturing industries.

    This study quantified greenhouse gas (GHG) emissions from the Pakistan Tobacco Company (PTC) production using a life cycle approach. The PTC production chain comprises of two phases: agricultural activities (Phase I) and industrial activities (Phase II). Data related to agricultural and industrial activities of PTC production chain were collected through questionnaire survey from tobacco growers and records from PTC manufacturing units. The results showed that total GHG emissions from PTC production chain were 44,965, 42,875, and 43,839 tCO2e respectively in 2009, 2010, and 2011. Among the agricultural activities, firewood burning for tobacco curing accounted for about 3117, 3565, and 3264 tCO2e, fertilizer application accounted for 754, 3251, and 4761 tCO2e in 2009, 2010, and 2011, respectively. Among the industrial activities, fossil fuels consumption in stationary sources accounted for 15,582, 12,733, and 13,203 tCO2e, fossil fuels used in mobile sources contributed to 2693, 3038, and 3260 tCO2e, and purchased electricity consumed resulted in 15,177, 13,556, and 11,380 tCO2e in 2009, 2010, and 2011, respectively. The GHG emissions related to the transportation of raw materials and processed tobacco amounted to 6800, 6301, and 7317 respectively in 2009, 2010, and 2011. GHG emissions from energy use in the industrial activities constituted the largest emissions (i.e., over 80%) of GHG emissions as PTC relies on fossil fuels and fossil fuel based electrical power in industrial processes. The total emissions of carbon footprint (CFP) from PTC production were 0.647 tCO2e per million cigarettes produced in 2009, 0.675 tCO2e per million cigarettes in 2010 and 0.59 tCO2e per million cigarettes in 2011. Potential strategies for GHG emissions reductions for PTC production chain include energy efficiency, reducing reliance on fossil fuels in non-mobile sources, adoption of renewable fuels including solar energy, energy from crop residues, and promotion of organic

    Recent estimates indicate that more than 2 billion scrap tires are currently stockpiled in the United States and approximately 280 million more tires are added annually. Various engineering applications utilize recycled tires in the form of shredded tire crumb rubber. However, the use of tire crumb rubber may have negative environmental impacts, especially when the rubber comes into contact with water. A review of the literature indicates that leaching of zinc from tire crumb rubber is the most significant water quality concern associated with using this material. Zinc is generally used in tire manufacturing, representing approximately 1.3% of the final product by mass. This study will report results from the U.S. Environmental Protection Agency’s (EPA’s) Synthetic Precipitation Leaching Procedure, batch leaching tests, and column leaching tests performed to quantify the process by which zinc leaches from tire crumb rubber into water. Results are interpreted with a first-order kinetic attachment/detachment model, implemented with the U.S. Agricultural Research Service software HYDRUS-1D, in order to determine the circumstances when zinc leaching from tire crumb rubber would be expected to comply with the applicable discharge limits. One potential application for recycled tires is replacing sand with tire crumb rubber in granular media filters used for stormwater pollution control. For this to be a viable application, the total zinc in the stormwater discharge must be below the EPA’s benchmark value of 0.117 mg/L.

    Rubber groves are attached each to an upper end of a glove putting vessel having an air-sucking hole on the bottom by enlarging an opening end of the rubber glove and turning back the inside to the outside. When the sucking device is operated, air in the glove putting device is sucked and the rubber glove is expanded by an atmospheric pressure. After expansion of the rubber glove to some extent, the sucking device is stopped, and presence or absence of failures of the rubber glove is confirmed by shrinkage of the rubber glove and by an indication value of a pressure gauge for detecting the pressure change in the vessel. Then, a hand is inserted to the expanded rubber glove, and a detaching switch in the vessel is pushed by a finger tip. A detaching piece at the upper end of the vessel is protruded outwardly to enlarge the turned-back portion of the rubber glove to easily release the rubber glove from the putting vessel, and the rubber glove is put on. This enables to wear the rubber glove and conduct failure test simultaneously. Further, a user can put on the rubber glove without touching the outside of the rubber glove. (I.N.)

    Dimethyl ether can cause degradation of the rubber material seal in some applications. In order to use of natural rubber in industry, research about a blending of natural rubber (NR) and nitrile rubber (NBR) to produce rubber to meet the standard seal material application were conducted. This study will observe the degradation mechanisms that occur in the blending natural rubber and nitrile rubber (NR/NBR) by dimethyl ether. Nitrile rubber types used in this study is medium quality nitrile rubber with 33% of acrylonitrile content (NBR33). The observed parameters are percent change in mass, mechanical properties and surface morphology. This study is limited to see the effect of variation vulcanized blending ratio (NR/NBR33) against to swelling. The increase of nitrile rubber (NBR33) ratio of blending rubber vulcanized can reduce the tensile strength and elongation. The best elastomer variation was obtained after comparing with the standard feasibility material of seal is rubber vulcanized blending (NR/NBR33) with ratio 40:60 NR: NBR.

    To better understand job rotation in the manufacturing industry, we completed a systematic review asking the following questions: 1) How do job-rotation programs impact work-related musculoskeletal disorders (MSDs) and related risk control for these MSDs, as well as psychosocial factors? and 2) How best should the job rotation programs be designed? We searched MEDLINE, EMBASE, Business Source Premier, ISI Web of Knowledge, CINAHL, PsyINFO, Scopus, and SciELO databases for articles published in peer-reviewed journals. Eligible studies were examined by two independent reviewers for relevance (population of manufacturing workers, outcomes of musculoskeletal disorders, physical factors, psychosocial factors, and strategies used in job-rotation implantation) and methodological quality rating. From 10,809 potential articles, 71 were read for full text analysis. Of the 14 studies included for data extraction, two were non-randomized control trial studies, one was a case-control study, and 11 were cross-sectional comparisons. Only one, with a case-control design, was scored with good methodological quality. Currently, weak evidence exists supporting job rotation as a strategy for the prevention and control of musculoskeletal disorders. Job rotation did not appear to reduce the exposure of physical risk factors; yet, there are positive correlations between job rotation and higher job satisfaction. Worker training has been described as a crucial component of a successful job-rotation program. The studies reported a range of parameters used to implement and measure job-rotation programs. More rigorous studies are needed to better understand the full impact of job rotation on production and health. CRD42014013319. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Spain and Brazil are two of the world's biggest ceramic tile producers. The tile manufacturing process consumes a great quantity of thermal energy that, in these two countries, is mainly obtained from natural gas combustion, which entails CO 2 emission, a greenhouse gas. This study presents a comparative analysis of the thermal energy consumption and CO 2 emissions in the ceramic tile manufacturing process in Spain and Brazil, in terms of the different production technologies and different products made. The energy consumption and CO 2 emissions in ceramic tile manufacture by the wet process are very similar in both countries. In the dry process used in Brazil, less thermal energy is consumed and less CO 2 is emitted than in the wet process, but it is a process that is only used in manufacturing one particular type of product, which exhibits certain technical limitations. While in Spain the use of cogeneration systems in spray-dryers improves significantly the global energy efficiency. The average energy consumption in the different process stages, in both countries, lies within the range indicated in the Reference Document on Best Available Techniques in the Ceramic Manufacturing Industry (BREF of the Ceramic Manufacturing Industry) of the European Union.

    2016-04-01

    Full Text Available Furniture manufacturing in Malaysia is an established industry driven primarily by the availability of raw materials and labor. However, the industry suffers from the low-recovery rate of its materials, as it produces a substantial amount of waste during the manufacturing process. Although smaller waste fragments, or off-cuts, are recovered for other purposes, the splinters, shavings, and coarse dust have little economic value and are often discarded. Because wood is a well-established source of bioenergy, this study investigated the potential use of mill waste from the furniture-manufacturing industry for electrical energy generation. Waste from the rubberwood, bamboo, and rattan furniture industries was evaluated for its potential electrical energy generation, and the amount was compared with the electrical energy that was consumed by the furniture industry. The study also compared the emission of greenhouse gases from the combustion of these waste materials against fossil fuels used to generate electricity to assess its potential in terms of the environmental benefits. In conclusion, such mill waste could be utilized as substitute for fossil fuel to generate energy in the furniture industry.

    Korea is well known for its long work hours amongst employees. Because workers of the manufacturing industry are constantly exposed to extended work hours, this study was based on how long work hours affect their emotional well-being. The analysis was done using the secondary Korean Working Condition Survey (KWCS). Long work hours were defined to be more than 48 hours, and they were subcategorized into units of 52 hours and 60 hours. Based on the WHO (five) well-being index, emotional state was subdivided into three groups - reference group, low-mood group, and possible depression group- where 28 points and 50 points were division points, and two groups were compared at a time. Association between long work hours and emotional state was analyzed using binary and multinomial logistic regression analysis. Working for extended working hours in the manufacturing industry showed a statistically significant increase (t test p work-related characteristics were fixed as controlled variables, as work hours increased the odds ratio of the possible depression group increased compared to the reference group, and especially the odds ratio was 2.73 times increased for work hours between 48-52 and 4.09 times increased for 60 hours or more and both were statistically significant. In comparing the low-mood group and possible depression group, as work hours increased the odds ratio increased to 1.73, 2.39, and 4.16 times, and all work hours from working 48-52 hours, 53-60 hours, and 60 hours or more were statistically significant. Multinomial logistic regression analysis also showed that among the reference group and possible group, the possible depression group was statistically significant as odds ratio increased to 2.94 times in working 53-60 hours, and 4.35 times in 60 hours or more. Long work hours have an adverse effect on emotional well-being. A more diversified research towards variables that affect long work hours and emotional well-being and how they interact with each

    2011-05-15

    Modern manufacturing of printed wiring boards (PWBs) involves extensive use of various hazardous chemicals in different manufacturing steps such as board preparation, circuit design transfer, etching and plating processes. Two complementary environmental screening methods developed by the U.S. EPA, namely: (i) the Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) and (ii) Risk-Screening Environmental Indicators (RSEI), are used to quantify geographic and chemical environmental impacts in the U.S. PWB manufacturing industry based on Toxics Release Inventory (TRI) data. Although the release weight percentages of industrial chemicals such as methanol, glycol ethers and dimethylformamide comprise the larger fraction of reported air and water emissions, results indicate that lead, copper and their compounds' releases correspond to the highest environmental impact from toxicity potentials and risk-screening scores. Combining these results with further knowledge of PWB manufacturing, select alternative chemical processes and materials for pollution prevention are discussed. Examples of effective pollution prevention options in the PWB industry include spent etchant recovery technologies, and process and material substitutions. In addition, geographic assessment of environmental burden highlights states where promotion of pollution prevention strategies and emissions regulations can have the greatest effect to curb the PWB industry's toxic release impacts.

    In this laboratory study, a process has been developed for selectively leaching zinc and manganese from pyrometallurgical sludge produced in the steel manufacturing industry. In the first part, the yield of Zn extraction was studied using four factors and four levels of the Box-Behnken response surface design. The optimum conditions for the step of Zn leaching were determined to be a sulfuric acid concentration of 0.25 mol/L, a pulp density of 10%, an extraction temperature of 20 °C, and three stages of leaching. Under such conditions, 75% of the Zn should be leached. For Mn leaching, the optimum conditions were determined to be a sulfuric acid concentration of 0.25 mol/L, a Na2S2O5/Mn stoichiometry of 1, a leaching time of 120 min and two leaching steps. In this case, 100% of the Mn should be leached. Copyright © 2015 Elsevier Ltd. All rights reserved.

  16. Manufacturing economics of plant-made biologics: case studies in therapeutic and industrial enzymes.

    Tusé, Daniel; Tu, Tiffany; McDonald, Karen A

    2014-01-01

    Production of recombinant biologics in plants has received considerable attention as an alternative platform to traditional microbial and animal cell culture. Industrially relevant features of plant systems include proper eukaryotic protein processing, inherent safety due to lack of adventitious agents, more facile scalability, faster production (transient systems), and potentially lower costs. Lower manufacturing cost has been widely claimed as an intuitive feature of the platform by the plant-made biologics community, even though cost information resides within a few private companies and studies accurately documenting such an advantage have been lacking. We present two technoeconomic case studies representing plant-made enzymes for diverse applications: human butyrylcholinesterase produced indoors for use as a medical countermeasure and cellulases produced in the field for the conversion of cellulosic biomass into ethanol as a fuel extender. Production economics were modeled based on results reported with the latest-generation expression technologies on Nicotiana host plants. We evaluated process unit operations and calculated bulk active and per-dose or per-unit costs using SuperPro Designer modeling software. Our analyses indicate that substantial cost advantages over alternative platforms can be achieved with plant systems, but these advantages are molecule/product-specific and depend on the relative cost-efficiencies of alternative sources of the same product.

    Some of the ethical, environmental and social issues relating to the design and use of machine vision systems in manufacturing industry are highlighted. The authors' aim is to emphasize some of the more important issues, and raise general awareness of the need to consider the potential advantages and hazards of machine vision technology. However, in a short article like this, it is impossible to cover the subject comprehensively. This paper should therefore be seen as a discussion document, which it is hoped will provoke more detailed consideration of these very important issues. It follows from an article presented at last year's workshop. Five major topics are discussed: (1) The impact of machine vision systems on the environment; (2) The implications of machine vision for product and factory safety, the health and well-being of employees; (3) The importance of intellectual integrity in a field requiring a careful balance of advanced ideas and technologies; (4) Commercial and managerial integrity; and (5) The impact of machine visions technology on employment prospects, particularly for people with low skill levels.

  18. Microbubble enhanced ozonation process for advanced treatment of wastewater produced in acrylic fiber manufacturing industry

    2015-02-02

    This work investigated microbubble-ozonation for the treatment of a refractory wet-spun acrylic fiber wastewater in comparison to macrobubble-ozonation. CODcr, NH3-N, and UV254 of the wastewater were removed by 42%, 21%, and 42%, respectively in the microbubble-ozonation, being 25%, 9%, and 35% higher than the removal rates achieved by macrobubble-ozonation at the same ozone dose. The microbubbles (with average diameter of 45μm) had a high concentration of 3.9×105 counts/mL at a gas flow rate of 0.5L/min. The gas holdup, total ozone mass-transfer coefficient, and average ozone utilization efficiency in the microbubble-ozonation were 6.6, 2.2, and 1.5 times higher than those of the macrobubble-ozonation. Greater generation of hydroxyl radicals and a higher zeta potential of the bubbles were also observed in the microbubble ozonation process. The biodegradability of the wastewater was also significantly improved by microbubble-ozonation, which was ascribed to the enhanced degradation of alkanes, aromatic compounds, and the many other bio-refractory organic compounds in the wastewater. Microbubble-ozonation can thus be a more effective treatment process than traditional macrobubble-ozonation for refractory wastewater produced by the acrylic fiber manufacturing industry.

    2008-01-01

    Full Text Available Exploitation of low and medium temperature thermal sources, in particular those based on biomass combustion and on industrial residual heat recovery, has been increasingly investigated in the last decades, accordingly to the growing interest towards reduction in primary energy consumption and environmental issues. Organic Rankine cycle technology allows designing power plants that are less demanding in terms of auxiliaries, safety systems, maintenance and operating costs when compared to conventional water steam power plants. To support the preliminary technical and economic design of this kind of plants in different contexts, a simulation code of part load and off-design operation of an organic Rankine cycle unit for combined heat and power has been developed. In the paper, taking the real situation of a furniture manufacturing factory as a starting point, it is shown how all energy flows occurring all year long inside the combined heat and power plant, can be estimated on the basis of the thermal user duty time profile, the available biomass flow rate and the adopted operation strategy. This information is the basis in order to correctly evaluate the energetic, economic and environmental advantages of the proposed technical solution, with respect to a particular context, as it is shown in the concluding part of the paper.

    Electric power deregulation in Japan opens opportunity for further penetration of on-site generation (cogeneration) otherwise known as distributed generation. In the paper the authors present a survey on Japanese industrial plants to fill existing gaps for the assessment of modern cogeneration (combined heat and power, CHP). The objective of the paper is to empirically examine CHP systems based on cross-sectional binary models; second to review diffusion trends of CHP by system vintage during the 1980-2000 period in the manufacturing sector. The econometric results point that the probabilities of embracing this technology increase, in declining importance, with on-site power consumption, and steam demand, operational hours as well as with payback period, purchased power. For example the survey shows that the CHP is used for the purpose of exporting power rather than meeting the plant's own consumption. Some of our results are in line with those of Dismukes and Kleit (Resource Energy Econ. 21 (1999) 153) as well with Rose and Macdonald (Energy J. 12(12) (1991) 47). We also find that a unit increase in satisfaction with CHP will lead to a 54% in CHP capacity. We find significant evidence on the cost effectiveness of CHP under conservative assumptions. Regarding the influence of satisfaction and performance indicators for the several plants, the survey threw some unexpected evidence on the nature of CHP

    Full Text Available In this paper, for the sake of improving the reparatory hard-facing technology is especially analyzed reparatory hard-facing of tools for manufacturing compressed products in confectionary industry. Those products are being made of a mixture consisting of several powdery components, which is compressed under high pressure. In that way the connection between particles is realized, thus achieving certain hardness and strength of the confectionary product. The considered tool is made of high-alloyed stainless steel. The tool contains 30 identical working places. Besides the production process wear, on those tools, from time to time, appear mechanical damage on some of the products' shape punches, as cracks at the edges, where the products' final shapes are formed. Those damages are small, size wise, but they cause strong effect on the products' final shape. The aggravating circumstance is that the shape punch is extremely loaded in pressure, thus after the reparatory hard-facing, the additional heat treatment is necessary. Mechanical properties in the heat affected zone (HAZ are being leveled by annealing and what also partially reduces the residual internal stresses.

    Full Text Available A variety of social enterprises (SEs have recently emerged in many different countries in an effort to resolve diverse social problems. However, the value creation mechanism of SEs has not yet been disclosed. The purpose of this study is to reveal the value creation mechanism of SEs in manufacturing industry. To do so, we verify the role of social entrepreneurship and examine the effects of product innovation attributes and social capital on social value creation and financial performance by using structural equation modelling. Then, we conduct interviews with six experts in SE fields. According to the results of empirical study, the social entrepreneurship works as an antecedent of product innovation and social capital in SEs and the degrees of products’ simplicity, usability and standardization positively affect the social value creation of SEs. In addition, the social value creation works as a complete mediator between the product innovation of SEs and their financial performance. The interviews suggest policy implications for successful social value creation and sustainability of SEs. This research contributes towards further studies on innovation of SEs and provides social entrepreneurs with guidelines in planning their innovation strategy or developing their products.

    2016-01-01

    Climate change has become one of the most challenging issues facing the world. Chinese government has realized the importance of energy conservation and prevention of the climate changes for sustainable development of China's economy and set targets for CO_2 emissions reduction in China. In China industry contributes 84.2% of the total CO_2 emissions, especially manufacturing industries. Data envelopment analysis (DEA) and Malmquist productivity (MP) index are the widely used mathematical techniques to address the relative efficiency and productivity of a group of homogenous decision making units, e.g. industries or countries. However, in many real applications, especially those related to energy efficiency, there are often undesirable outputs, e.g. the pollutions, waste and CO_2 emissions, which are produced inevitably with desirable outputs in the production. This paper introduces a novel Malmquist–Luenberger productivity (MLP) index based on directional distance function (DDF) to address the issue of productivity evolution of DMUs in the presence of undesirable outputs. The new RAM (Range-adjusted measure)-based global MLP index has been applied to evaluate CO_2 emissions reduction in Chinese light manufacturing industries. Recommendations for policy makers have been discussed. - Highlights: •CO_2 emissions reduction in Chinese light manufacturing industries are measured. •A novel RAM based Malmquist–Luenberger productivity index has been developed. •Recommendation to policy makers for reducing CO_2 reduction in China are given.

  8. Role of embodied energy in the European manufacturing industry: Application to short-term impacts of a carbon tax

    Bordigoni, Mathieu; Hita, Alain; Le Blanc, Gilles

    2012-01-01

    Role of energy in the manufacturing industry is a major concern for energy and environmental policy design. Issues like energy prices, security of supply and carbon mitigation are often connected to the industry and its competitiveness. This paper examines the role and consequences of embodied energy in the European industry. To this end, a multi-regional input–output analysis including 59 industrial sectors for all European Union countries and 17 more aggregated industries for other regions of the World is developed. Other segments of the economy are not included. This base is combined with energy consumption, carbon emission as well as bilateral trade data for every sector in all included countries. Our main result is that embodied energy in manufactured products' imports represents a significant aspect of the energy situation in European industries, with quantities close to the direct energy consumption. These flows can further be broken down for detailed analysis at the sector level thanks to the number of distinct industries included. Results demonstrate that an important part of embodied energy inside European products is not concerned with domestic energy price changes. In addition, a European-wide carbon tax would induce an unbalanced burden on industries and countries. - Highlights: ► We calculate embodied energy and carbon flows in the European and World industry. ► A multi-regional input–output analysis is used with a detailed nomenclature. ► National industries' energy prices dependence is a domestic issue. ► With a European carbon tax energy-intensive industries would be penalised. ► Such a tax may also induce competition distortion among EU countries.

    2018-01-01

    Full Text Available Deflashing is the process of removal of excess flashes from the rubber products. Initially deflashing was a manual operation where dozen of workers, seated at small work stations would take each part and trim the excess rubber off with scissors, knives or by grinding. Still the same method is employed in most of the rubber industry. The drawbacks of this method are demand inconsistent and repeatable quality. Work done by hand is often inconsistent. There are commercially available cryogenic deflashing machine but they are too expensive hence cost effectiveness is also a prime factor. The objective of this paper is to develop a technique, to identify the media through which the flashes can be removed easily and effectively. Based on the test results obtained from testing of five different types of media, ABCUT Steel media gave best results. The testing of the ABCUT Steel media on rubber samples like O-rings, grommet tail door, bottom bush etc. shows good results.

  11. Sustaining Competitiveness: Moving Towards Upstream Manufacturing in Specialized-Market-Based Clusters in the Chinese Toy Industry

    Directory of Open Access Journals (Sweden)

    Huasheng Zhu

    2016-02-01

    Full Text Available Western industrial cluster literature pays little attention to specialized markets (SMs and the geographical agglomeration of distributors or sale agencies (SAs. This paper takes Linyin, Shandong, a famous commodity city in Northeastern China, as an example, to discuss the determinants that make SAs in SMs of the toy industry move towards upstream manufacturing. A structured questionnaire survey and subsequent interviews were carried out during 2011 and 2012 to collect data, and a Binary Logistic Regression Model was used to process the data. This paper looks from the perspective of global production networks theory, establishes an analytical framework that combines individual motivations of intra-firm coordination, local inter-firm relationships and dynamic cross-regional level relationships. The findings indicate that the expansion of SAs towards manufacturing allows them to sustain competitiveness under changing circumstances. The local inter-firm relationships within SM-based clusters not only makes it easy to obtain material and human resources with lower manufacturing costs, but also facilitates the access to production knowledge and technologies for an expansion of production scale. Cross-regional relationships with suppliers provide an informal channel for SAs to obtain skills, which is fundamental for an expansion into manufacturing. In addition, it is a preference for strengthening competitiveness rather than the simple pursuit of economic profit that encourages SAs to invest in manufacturing.

    Full Text Available Used tyre rubber wastes present a serious environmental problem of pollution and storage. The recycling of this waste in the industry of construction could be an appropriate solution to produce an eco-concrete and could contribute to the improvement of some of its properties. This paper aims to study the possibility of using tyre rubber waste as fine aggregate replacement in self-compacting concrete (SCC. Fines rubber particles of 0-2 mm of waste tyres were added SCC mixtures as a partial substitution of the total volume of sand at different percentages (5, 10, 15, 20 and 30%. The influence of fines rubber of used tyres on fresh and hardened properties of the SCC was investigated. The fresh properties of SCC were performed by using slump-flow, T50 flow time, L-box, V-funnel and segregation resistance tests. Characteristics of the hardened state were obtained by compressive strength and thermal conductivity. The experimental results showed that the inclusion of fines rubber in SCC decreases the workability, reduced its passing capacity and increases the possibility of blocking. A decrease in compressive strength is observed with the increase in rubber content. On the other hand, the incorporation of the rubber fines aggregates enhances in a remarkably way the thermal conductivity.

    Fresh natural latex (around 40% rubber and 60% water) can be transformed to concentrated natural latex (around 60% rubber and 40% water) in order to realise economical transportation and easier latex product’s preparation. The concentrated natural latex is an extremely valuable material. It can be applied for many types of products, for example, foam rubber as pillow and mattress, elastic band, etc. Industrially, the concentrated natural latex can be prepared by centrifugation which requires an enormous expensive machine. From the eco-friendly products point of view, most of rubber entrepreneurs in the world try to develop a green rubber product. So, the main objective of this study is to prepare the cream concentrated latex without any sophisticated machine. Thus, we work on a simple, cheap and green method that does not use any expensive machine but uses water-based chemical as sodium alginate to prepare the cream concentrated latex. The optimal amount of sodium alginate in the latex was studied. The main characteristics of the cream concentrated latex were tested by various technics, such as alkalinity, total solid content (TSC), dry rubber content (DRC), etc. We found that there are no significant differences of results between fresh natural latex and cream concentrated latex, except for the TSC and DRC. The TSC and DRC of cream latex are higher than those of fresh natural latex. Finally, we propose a model of natural rubber particle and sodium alginate to form the cream concentrated latex.

    Full Text Available In the following project, the theory of constraints was applied in order to implement a manufacture CAD-CAM system into the metal mechanic industry processes of polymers injection and blown of polymers. The research showed that the manufacture of the mold with the engraving took 223,17 hours. In the workflow for the manufacture of the mold, a restriction was found in the outsource service of CNC. It took 120 hours of the whole process and represent the 51,47 % the total time of tooling manufacturing. There is also a constraint found in the design time. It was 60 hours that corresponds to 26,88 % of the overall time. In order to reduce the time, a modern system of design in 3D and CAM was established to improve the model process of design and manufacture. A simulation by computational resource was applied to the plastic. The design was changed from 2D to 3D. The implementation was focused in the design. A software was installed to improve the speed of modeling methods with reliable information. In the manufacture of molds, a new CNC machine was acquired with three simultaneous axes to eliminate the outsource service. By acquiring the design system, the working time was diminished in 79% and regarding to the CNC process, the working time was improved in 88%.

  1. Air Pollution and 'Dirty' Industries. How and Why Does the Composition of Manufacturing Output Change with Economic Development?

    International Nuclear Information System (INIS)

    Cole, M.A.

    2000-01-01

    This paper examines the impact on air pollution of changes in the composition of manufacturing output in developed and developing countries. Pollution emissions from manufacturing output are estimated in a manner which holds constant the effect of technology and regulations allowing the impact of compositional changes alone on pollution to be estimated. The paper has three main findings; (1) the inverted-U estimated between per capita income and the pollution intensity of GDP arises due to both the composition of manufacturing becoming cleaner and the share of manufacturing output in GDP falling. Compositional changes alone are not responsible for the inverted-U between per capita income and per capita emissions; (2) changes to the composition of manufacturing output are consistent with the pollution haven hypothesis, however there is clear evidence that rising per capita incomes are associated with a failing income elasticity of demand for 'dirty' products. This fact may explain the compositional changes that occur with development; (3) in addition to the income elasticity effect, the analysis suggests that land prices and to a lesser extent the prices of labour and capital, determine the proportion of dirty industry within a country's manufacturing sector. 27 refs

    2012-06-01

    The purpose of this study is to evaluate the tire manufacturing work environments extensively and to identify workers' exposure to hazardous substances in various work processes. Personal air sampling was conducted to measure polycyclic aromatic hydrocarbons, carbon disulfide, 1,3-butadiene, styrene, methyl isobutyl ketone, methylcyclohexane, formaldehyde, sulfur dioxide, and rubber fume in tire manufacturing plants using the National Institute for Occupational Safety Health Manual of Analytical Methods. Noise, carbon monoxide, and heat stress exposure were evaluated using direct reading instruments. Past concentrations of rubber fume were assessed using regression analysis of total particulate data from 2003 to 2007, after identifying the correlation between the concentration of total particulate and rubber fume. Workers were exposed to rubber fume that exceeded 0.6 mg/m(3), the maximum exposure limit of the UK, in curing and production management processes. Forty-seven percent of workers were exposed to noise levels exceeding 85 dBA. Workers in the production management process were exposed to 28.1℃ (wet bulb globe temperature value, WBGT value) even when the outdoor atmosphere was 2.7℃ (WBGT value). Exposures to other substances were below the limit of detection or under a tenth of the threshold limit values given by the American Conference of Governmental Industrial Hygienists. To better classify exposure groups and to improve work environments, examining closely at rubber fume components and temperature as risk indicators in tire manufacturing is recommended.

    Full Text Available Abstract The objective of this paper was to present the factors that impede the implementation of ISO 9000 QMS within the manufacturing and service Industry of Ivory Coast. It wasnt the intention of the author to provide detailed strategies for the readers to implement ISO 9000. It was an effort to present the relationship if any between the lack of ISO 9000 adoption and the perception of Ivoirians business organization leaders. For that purpose five research questions were associated with this study. The population for this study was all non-ISO certified business organizations in both public and private sector and was physically located in Ivory Coast. The population sample for this study was the 5044 members of the Chambre de Commerce et dIndustrie de Cote dIvoire CCI from which the author utilized the sample size of 60 business organizations randomly selected. This study utilized a survey questionnaire of face to face interview as data collection method. The survey questionnaire contained thirty three 33 questions organized in six parts and was proposed to 60 business organizations leaders. The result showed that business organization leaders in Ivory Coast were aware of the ISO 900 QMS but do not have enough knowledge on the ISO 9000 QMS implementation and certification. This could be due to the poor job done by CODIMORM the local national bureau of standards as a source of information. However it was found that business organization leaders in Ivory Coast intended to pursue and obtain ISO 9000 QMS certification. With respect to perceived benefits they indicated customer satisfaction improvement as the most important benefit that ISO 9000 QMS certification could bring to their general management activities. With respect to perceived improvements they selected quality of productsservices as the most important improvement that ISO 9000 QMS implementation and certification could help to achieve.

    Objective: To explore the applicability of 2 different models of occupational health risk assessment in wooden furniture manufacturing industry. Methods: American EPA inhalation risk model and ICMM model of occupational health risk assessment were conducted to assess occupational health risk in a small wooden furniture enterprises, respectively. Results: There was poor protective measure and equipment of occupational disease in the plant. The concentration of wood dust in the air of two workshops was over occupational exposure limit (OEL) , and the C TWA was 8.9 mg/m 3 and 3.6 mg/m 3 , respectively. According to EPA model, the workers who exposed to benzene in this plant had high risk (9.7×10 -6 ~34.3×10 -6 ) of leukemia, and who exposed to formaldehyde had high risk (11.4 × 10 -6 ) of squamous cell carcinoma. There were inconsistent evaluation results using the ICMM tools of standard-based matrix and calculated risk rating. There were very high risks to be attacked by rhinocarcinoma of the workers who exposed to wood dust for the tool of calculated risk rating, while high risk for the tool of standard-based matrix. For the workers who exposed to noise, risk of noise-induced deafness was unacceptable and medium risk using two tools, respectively. Conclusion: Both EPA model and ICMM model can appropriately predict and assessthe occupational health risk in wooden furniture manufactory, ICMM due to the relatively simple operation, easy evaluation parameters, assessment of occupational - disease - inductive factors comprehensively, and more suitable for wooden furniture production enterprise.

    Kirkhill Rubber Company (KRC) has informed Thiokol Corporation that two raw materials used in the asbestos and silica filled acrylonitrile butadience rubber (NBR) formulation per STW 2621 are no longer available from their vendors. Agerite White (Di-beta-naphthyl-paraphenylene diamine), manufactured by B. F. Goodrich, is an antioxidant used in NBR. This raw material makes up roughly 1-2 percent of the finished product. KRC proposed that this raw material be replaced by Agerite Stalite S (mixture of octylated diphenylamines) distributed by R. T. Vanderbilt Co. Protox-166 zinc oxide, manufactured by Zinc Corporation of America, is an activator currently used in NBR. This material also makes up about 1-2 percent of the finished material. Protox-166 is an American process grade zinc oxide. It is proposed by KRC to replace Protox-166 with Kadox-930C, a French process grade zinc oxide. American process grades have an ASTM minimum purity of 99.0 percent; the French process grades have a minimum purity of 99.5 percent. Previous testing per WTP-0270 has demonstrated that the mechanical and thermal properties of the rubber with the new ingredients are comparable to the 'old' rubber. The test results are reported in TWR-61790. One igniter adapter, Part no. 7U77562-02 serial no. 2 was insulated per ETP-1206 using the new rubber formulation and a modified lay up and cure method to demonstrate that there is no impact on this process. The results of this demonstration are reported.

    Details of the Ontario Tire Recycling and Economic Development (OnTRED) plan were presented. The plan was developed to address deficiencies in the Ontario Tire Stewardship's (OTS) Scrap Tire Diversion Program plan. The OTS promotes the burning of scrap tires contrary to the Waste Diversion Act, and transfers the financial responsibility for scrap tire management from manufacturers to retailers. The OnTRED plan will attempt to improve the current 87 per cent recovery rate for passenger scrap tires in Ontario, and prevent the formation of any new tire stockpiles. The aim of the OnTRED plan is to ensure reuse and recycling consistent with provisions in the Waste Diversion Act and enhance the existing workings of the tire and scrap tire market through the promotion of reuse and recycling. In addition, the plan aims to minimize administration and compliance costs. A program summary of the OnTRED plan was presented, as well as details of market development plans and buy-recycled rebates. Issues concerning collector registration and transaction tracking were presented, as well as details of brand-owner and first importer pay-in models. Stakeholder roles and responsibilities were reviewed. A budget scenario was presented, as well as a rebate and diversion scenario. It was concluded that Ontario's 87 per cent scrap tire diversion rate can be improved through a focus on patterns of reuse and recycling. 3 tabs., 7 figs.

    Natural rubber, cis-1,4-polyisoprene, is an important raw material in chemical industries, but its biosynthetic mechanism remains elusive. Natural rubber is known to be synthesized in rubber particles suspended in laticifer cells in the Brazilian rubber tree (Hevea brasiliensis). In the rubber tree, rubber elongation factor (REF) and its homolog, small rubber particle protein (SRPP), were found to be the most abundant proteins in rubber particles, and they have been implicated in natural rubber biosynthesis. As lettuce (Lactuca sativa) can synthesize natural rubber, we utilized this annual, transformable plant to examine in planta roles of the lettuce REF/SRPP homologs by RNA interference. Among eight lettuce REF/SRPP homologs identified, transcripts of two genes (LsSRPP4 and LsSRPP8) accounted for more than 90% of total transcripts of REF/SRPP homologs in lettuce latex. LsSRPP4 displays a typical primary protein sequence as other REF/SRPP, while LsSRPP8 is twice as long as LsSRPP4. These two major LsSRPP transcripts were individually and simultaneously silenced by RNA interference, and relative abundance, polymer molecular weight, and polydispersity of natural rubber were analyzed from the LsSRPP4- and LsSRPP8-silenced transgenic lettuce. Despite previous data suggesting the implications of REF/SRPP in natural rubber biosynthesis, qualitative and quantitative alterations of natural rubber could not be observed in transgenic lettuce lines. It is concluded that lettuce REF/SRPP homologs are not critically important proteins in natural rubber biosynthesis in lettuce. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available At present, the development of alternative products for elastomers based on recycling petrochemical raw materials is a new trend of the rubber industry progress. Petrochemical raw materials include spent lubricants and motor oils are among such recycling products. In this context, the influence of the products of recycling waste engine oil (DVCH and RA in comparison with industrial oil (I-20 on the technological properties of filled elastomeric compositions was investigated. The elastomeric compositions were based on poly isoprene and divinyl rubbers. The plasticizing components were manufactured by IOOO “DVCH-Menedzhment”. They are mixture of hydro-carbons, C16–C20 and differ from each other in the content of linear and branched paraffin. Plastic-elastic properties of rubber compounds on the shear disk viscometer MV2000 in accordance with GOST 10722–76 was carried out. Kinetics of vulcanization on the rheometer ODR2000 according to GOST 12535–84 was defined. It is shown that the introduction of RA test plasticizing component provides a significant effect on Mooney viscosity, as compared to elastomeric compositions containing a plasticizer and I-20 and plasticizing additive DVCH. It revealed that the administration of all components in the studied plasticizing elastomer compositions based on a combination poly isoprene and divinyl rubbers has no significant effect on the rate of relaxation of stress of rubber compounds. It is found that elastomeric compositions containing as additives investigated processing waste oil products (DVCH and RA are characterized by a slightly smaller value of time to reach an optimal degree of vulcanization.

    With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it.

    Full Text Available Leather is a fibrous protein consisting of collagen in a three dimensionally crosslinked network. Chrome tanning of leather improves the appearance of leather but at the same time emits both solid and liquid chrome leather wastes. Scrap rubber recycling using untreated and neutralized leather fibrous particles in natural rubber has been studied. Vulcanization, mechanical, morphological and swelling properties of the natural rubber - scrap rubber composites containing neutralized leather have been discussed. Use of chrome leather particles has been found to improve the consumption of scrap rubber powder in natural rubber formulations. Polymer composites based on leather wastes as fillers are reported to be useful for many applications such as in construction materials, automobile interior moldings, heat and sound insulating boards, shoe soles, flooring materials and moldings with good anti-static properties, air permeability and good appearances.

    Magnetic Rubber Inspection (MRI) was developed to inspect for small cracks and flaws encountered in high performance aircraft. A formula of very fine magnetic particles immersed in a room temperature curing rubber is catalysed and poured into dams (retainers) on the surface of the part to be inspected. Inducing a magnetic field then causes the particles to be drawn to discontinuities in the component under test. These indicating particles are held to the discontinuity by magnetic attraction, as the rubber cures. The solid rubber cast (Replica) is then removed and examined under a microscope for indicating lines of particle concentrations. 3 refs., 6 figs

    2013-04-15

    The purpose of this research was to develop and test a transformational combustion technology for high temperature furnaces to reduce the energy intensity and carbon footprint of U.S. manufacturing industries such as steel, aluminum, glass, metal casting, and petroleum refining. A new technology based on internal and/or external Flue Gas Recirculation (FGR) along with significant enhancement in flame radiation was developed. It produces "Radiative Flameless Combustion (RFC)" and offers tremendous energy efficiency and pollutant reduction benefits over and above the now popular "flameless combustion." It will reduce the energy intensity (or fuel consumption per unit system output) by more than 50% and double the furnace productivity while significantly reducing pollutants and greenhouse gas emissions (10^3 times reduction in NOx and 10 times reduction in CO & hydrocarbons and 3 times reduction in CO2). Product quality improvements are also expected due to uniform radiation, as well as, reduction in scale/dross formation is expected because of non-oxidative atmosphere. RFC is inexpensive, easy to implement, and it was successfully tested in a laboratory-scale furnace at the University of Michigan during the course of this work. A first-ever theory with gas and particulate radiation was also developed. Numerical programs were also written to design an industrial-scale furnace. Nine papers were published (or are in the process of publication). We believe that this early stage research adequately proves the concept through laboratory experiments, modeling and computational models. All this work is presented in the published papers. Important conclusions of this work are: (1) It was proved through experimental measurements that RFC is not only feasible but a very beneficial technology. (2) Theoretical analysis of RFC was done in (a) spatially uniform strain field and (b) a planar momentum jet where the strain rate is neither prescribed nor uniform. Four important non

    2015-05-01

    Full Text Available In the age of globalization, the upgrading of China’s manufacturing industries has attracted great attention from both academicians and practitioners, as it certainly has great implications for the development of China and, even further, for the development of the whole world. To address this issue, the study clarifies the effects of the internal technological innovation capability (ITIC and external linkages (ELs on upgrading the Chinese automotive manufacturing industry (CAMI in the global value chain, in order to indicate the appropriate way for the CAMI to be further upgraded and provide references for the formulation of regional automotive industrial policies. Based on Chinese panel data, the results confirm that both ITIC and EL are important for the upgrading of the CAMI, with ITIC being the more important. Improvement of ITIC facilitates the industry’s cooperation with the EL, resulting in better knowledge access. Furthermore, the results of cluster analysis reveal that regions with relatively developed automotive industries place emphasis on both the ITIC and EL. However, in some regions (e.g., Shanghai and Chongqing, the utility of EL seems insufficient. Therefore, the results of this paper, on the one hand, suggest policies should be directed towards increasing the ITIC of CAMI. On the other hand, in some regions, managers and policymakers need to explore further the advantage of clustering.

  11. Prospects for global market expansion of China’s wind turbine manufacturing industry

    International Nuclear Information System (INIS)

    Gosens, Jorrit; Lu, Yonglong

    2014-01-01

    Emerging economies are increasingly contributing to global innovation, including clean-tech innovation. The development of China’s wind power sector has often been used to illustrate this point. China’s domestic wind power market is the largest in the world and is largely supplied by domestic manufacturers. Competition for market share in the domestic market may pressure firms to innovate, which consecutively improves prospects for global expansion. This paper reviews developments in China’s domestic wind turbine market using the Technological Innovation System framework. We analyze the pressure to innovate arising from market competition and assess the prospects for global expansion of Chinese wind turbine manufacturers. We conclude that domestic customers are not pressured or incentivized to perform with respect to power output, such that turbine manufacturers are not pressured to perform with respect to turbine efficiency or maintenance needs. Pressure to innovate is further reduced by formalizing connections between wind farm developers and turbine manufacturers. Chinese turbine manufacturers cannot yet compete with leading global brands in technological leadership. The prospects for exports are improved, however, by the preferential supply of project financing from institutional investors, such as the China Development Bank, from Chinese utilities that seek global expansion and from the manufacturers themselves. - Highlights: • We assess the pressure to innovate in the Chinese wind turbine market. • Customer demand is focused more strongly on turbine cost than quality. • Formalizing connections between users and suppliers reduce pressure to innovate. • Chinese manufacturers cannot yet compete globally in technological quality. • Preferential supplies of project finance may provide a vehicle for exports

  12. The Production, Value, and Reduction Responsibility of Carbon Emissions through Electricity Consumption of Manufacturing Industries in South Korea and Thailand

    Science.gov (United States)

    Kitikun, Medhawin

    This dissertation provides a new method of measuring efforts by manufacturing industries to reduce their emissions by curtailing electricity consumption. Employing comprehensive firm-level data from the National Manufacture Annual Surveys of South Korea and Thailand, I construct the measure from estimates of revenue functions by industry. The data consists of firms from more than 20 industries in each year from 1982 to 2005 for Korea and from 2001 to 2008 for Thailand. With a total of more than two million observations, I estimate revenue functions for each industry and year. Here, I use three inputs: number of employees(L), fixed asset stock(K), and electricity consumption(E) and two types of functional forms to represent each industry's revenue function. Second, under market competitive condition, I find that profit maximizing firms deviated their level of electricity usage in production from the profit-maximizing level during the time period for both countries, and I develop a theoretical framework to explain this behavior. Then, I tested the theory using my empirical models. Results support the notion of a hidden environmental value expressed by firms in the form of voluntary deviations from profit-maximizing levels of input demand. The measure used is the gap between the marginal revenue product of electricity and its price. This gap should increase with income, consistent with the Environmental Kuznets Curve literature. My current model provides considerable support for this proposition. Estimates indicate, in most industries, a negative relationship between per-capita income and emissions. In the final section of the dissertation, I consider the equitable distribution of emissions reduction burden under an international agreement such as the reduction effort, Kyoto Protocol. Both developed and developing countries have to cut their emissions to a specific reduction percentage target. Domestically, I present two extreme scenarios. In the first scenario

    Full Text Available Recently, Bangladesh readymade garments sector has started the trend of implementing ‘lean manufacturing’. To remain competitive in the global market the most important task for garments industry is to reduce the lead time which is also important for long-term stable development. A headlong rush to reduce lead time by becoming lean has created urgency for researchers and practitioners to apply new tools and techniques for dictating wastages. This research addresses the application of value stream mapping in garments industry to implement lean manufacturing. Value stream mapping is different than conventional recording approaches as it helps in the visualization of Material Flow, Information Flow, cycle times and utilization of resources. With the assurance of effective integration and communication, lean systems can be achieved with better efficiency. This research will stand as a benchmark to implement lean for other garment industries in Bangladesh.

    The demands for automobiles increased drastically in last two and half decades in India. Many global automobile manufacturers and Tier-1 suppliers have already set up research, development and manufacturing facilities in India. The Indian automotive component industry started implementing Lean practices to fulfill the demand of these customers. United Nations Industrial Development Organization (UNIDO) has taken proactive approach in association with Automotive Component Manufacturers Association of India (ACMA) and the Government of India to assist Indian SMEs in various clusters since 1999 to make them globally competitive. The primary objectives of this research are to study the UNIDO-ACMA Model as well as ISM Model of Lean implementation and validate the ISM Model by comparing with UNIDO-ACMA Model. It also aims at presenting a roadmap for Lean implementation in Indian automotive component industry. This paper is based on secondary data which include the research articles, web articles, doctoral thesis, survey reports and books on automotive industry in the field of Lean, JIT and ISM. ISM Model for Lean practice bundles was developed by authors in consultation with Lean practitioners. The UNIDO-ACMA Model has six stages whereas ISM Model has eight phases for Lean implementation. The ISM-based Lean implementation model is validated through high degree of similarity with UNIDO-ACMA Model. The major contribution of this paper is the proposed ISM Model for sustainable Lean implementation. The ISM-based Lean implementation framework presents greater insight of implementation process at more microlevel as compared to UNIDO-ACMA Model.

    Full Text Available Construction industry plays very important role in development of any country. The development of construction industry depends to a larger extent on quality of construction productions and projects. Quality of construction productions and projects is linked with the implementation of QMS (Quality Management System in construction organizations. ISO certification is one of the QMS which has been adopted in manufacturing and construction industry at the global level. The construction companies of developing countries have reaped many advantages from the effective implementation of ISO standards. The rate of adoption of ISO standards has remained slow in the construction sector of some developing countries like Pakistan. This paper presents the literature review of ISO in global construction industry. It highlights the advantages, disadvantages and barriers faced by construction companies in the implementation of ISO standards. This study also investigates the level of adoption of ISO standards in construction and manufacturing companies of Pakistan through a questionnaire survey. It presents the comparison of ISO standards\\\\\\' adoption in both construction and manufacturing sectors. The paper puts forward some suggestions and recommendation for the better adoption and improvement of ISO implementation in the construction sector of Pakistan. This study emphasizes that construction companies of Pakistan should learn from the benefits reaped by the construction companies of developed countries and take appropriate measures for implementing ISO standards. It also suggests that public sector clients should make it obligatory for the contractors and consultants to have ISO certification before awarding the works in order to enhance the the adoption of ISO standards in construction sector.

    For the fabrication of customized silicone rubber based implants, e.g. cochlear implants or electrocortical grid arrays, it is required to develop high speed curing systems, which vulcanize the silicone rubber before it runs due to a heating related viscosity drop. Therefore, we present an infrared radiation based cross-linking approach for the 3D-printing of silicone rubber bulk and carbon nanotube based silicone rubber electrode materials. Composite materials were cured in less than 120 s and material interfaces were evaluated with scanning electron microscopy. Furthermore, curing related changes in the mechanical and cell-biological behaviour were investigated with tensile and WST-1 cell biocompatibility tests. The infrared absorption properties of the silicone rubber materials were analysed with fourier transform infrared spectroscopy in transmission and attenuated total reflection mode. The heat flux was calculated by using the FTIR data, emissivity data from the infrared source manufacturer and the geometrical view factor of the system.

    Sueyoshi, Toshiyuki; Goto, Mika

    2014-01-01

    A balance between industrial pollution prevention and economic growth becomes a world-wide issue to develop a sustainable society in many industrial nations. To discuss the issue, this study proposes a new use of DEA environmental assessment to determine how to effectively allocate capital for developing regional industries. The amount of capital is used to invest for technology innovation for both local economic growth and environmental protection. In this study, the proposed approach separates outputs into desirable and undesirable categories. Inputs are also separated into two categories, one of which indicates an amount of investment on capital assets. The other category is used for production activities. The proposed approach unifies them by two disposability concepts. This study has evaluated the performance of manufacturing industries in 47 prefectures (local government units in Japan) by Unified Efficiency under Natural disposability (UEN), Unified Efficiency under Managerial disposability (UEM) and Unified Efficiency under Natural and Managerial disposability (UENM). The UENM is further separated into its two cases: with and without a possible occurrence on desirable congestion, or technology innovation, on undesirable outputs. This study has empirically confirmed that Japanese manufacturing industries need to make their efforts to reduce greenhouse gas emissions and air pollution substances by investing in technology innovation. Furthermore, most of economic activities are currently located at metropolitan regions (e.g., Tokyo) in Japan. To develop a sustainable society, Japan needs to allocate capital into regions with a high level of investment effectiveness by shifting the manufacturing industries from the metropolitan regions to much promising local areas identified in this study. Such a shift, along with technology innovation, makes it possible to reduce air pollutions in the entire Japan by balancing economic growth and pollution prevention. This

    The purification of heparin from offal is an old industrial process for which commercial recipes date back to 1922. Although chemical, chemoenzymatic, and biotechnological alternatives for this production method have been published in the academic literature, animal-tissue is still the sole source for commercial heparin production in industry. Heparin purification methods are closely guarded industrial secrets which are not available to the general (scientific) public. However by reviewing the academic and patent literature, we aim to provide a comprehensive overview of the general methods used in industry for the extraction of heparin from animal tissue.

    Due to the increase in use and production of polymer materials, there is a constant pressure of finding a solution to more environmental friendly composites. Beside the constant effort of recycling used materials, it seems more appropriate to manufacture and use biodegradable and renewable row materials. Natural polymers like starch, cellulose, lignin etc are ideal for preparing biodegradable composites. Some of the dynamic markets that use polymer materials are the food and pharmaceutical industries. Because of their desinfastation and sometimes sterility requirements, different treatment processes are applied, one of it being radiation treatment. The scope of this paper is to analyze the mechanical behaviour of rubber based materials irradiated with gamma rays at four medium doses, 30.1 kGy, 60.6 kGy, 91 kGy and 121.8 kGy. The objectives are the following: to identify the optimum radiation dose in order to obtain a good mechanical behaviour and to identify the mechanical behaviour of the material when adding different quantities of natural filler (20 phr, 60 phr and 100 phr).

  3. Amphiphilic semi-interpenetrating polymer networks using pulverized rubber

    Science.gov (United States)

    Shahidi, Nima

    Scrap rubber materials provide a significant challenge to either reuse or safe disposal. Every year, millions of tires are discarded to landfills in the United States, consuming a staggering amount of land space, creating a high risk for large fires, breeding mosquitoes that spread diseases, and wasting the planet's natural resources. This situation cannot be sustained. The challenge of reusing scrap rubber materials is mainly due to the crosslinked structure of vulcanized rubber that prevent them from melting and further processing for reuse. The most feasible recycling approach is believed to be a process in which the vulcanized rubber is first pulverized into a fine powder and then incorporated into new products. The production of fine rubber particles is generally accomplished through the use of a cryogenic process that is costly. Therefore, development of a cost effective technology that utilizes a large quantity of the scrap rubber materials to produce high value added materials is an essential element in maintaining a sustainable solution to rubber recycling. In this research, a cost effective pulverization process, solid state shear extrusion (SSSE), was modified and used for continuous pulverization of the rubber into fine particles. In the modified SSSE process, pulverization takes place at high compressive shear forces and a controlled temperature. Furthermore, an innovative particle modification process was developed to enhance the chemical structure and surface properties of the rubber particles for manufacturing of high value added products. Modification of rubber particles was accomplished through the polymerization of a hydrophilic monomer mixture within the intermolecular structure of the hydrophobic rubber particles. The resulting composite particles are considered as amphiphilic particulate phase semi-interpenetrating polymer networks (PPSIPNs). The modified rubber particles are water dispersible and suitable for use in a variety of aqueous media

    2016-09-01

    Full Text Available Whereas formerly metallic materials were used extensively and for various purposes in the machines manufacturing industry, nowadays new materials are sought that can replace the "conventional" machines manufacturing materials with new ones. This is especially challenging in areas where parts need to be able to withstand very tough conditions, such as high temperatures or large forces applied to them. The current paper intends to analyze some of the most widely used materials for high-strength applications. A special focus in this regard is on the one hand in fiber-reinforced composite materials with the polymer matrix and on the other hand on basalt. The most important properties, processing technologies and applications of these materials are analyzed and discussed and conclusions are drawn regarding their compatibility with the intended purpose.

The results indicated that benzene and toluene were the major species associated with letterpress printing, while ethyl acetate and isopropyl alcohol were the most abundant compounds of other two printing processes. Acetone and 2-butanone were the major species observed in the shoemaking sector. The source profile patterns were found to be similar for the paint manufacturing, wood furniture coating, and metal surface coating sectors, with aromatics being the most abundant group and oxygenated VOCs (OVOCs) as the second largest contributor in the profiles. While OVOCs were one of the most significant VOC groups detected in these five industrial sectors in the PRD region, they have not been reported in most other source profile studies. Such comparisons with other studies show that there are differences in source profiles for different regions or countries, indicating the importance of developing local source profiles.

  13. The German model of capitalism and the persistence of outward foreign direct investment: evidence from German manufacturing industries

    Full Text Available Against the backdrop of critique on the German model of capitalism in general, and German public policy in particular as to the ability to successfully adjust to rapid change and exogenous shocks in wake of economic globalisation, this paper investigates the degree of shock persistence in foreign direct investment (FDI of ten German manufacturing industries for the period 1976 to 2003. Theory on exports and non-FDI investment suggests that FDI should exhibit a considerable degree of shock persistence because they are subject to high sunk costs because of high entry and exit costs associated with the high level of asset specificity that is normally connected to FDI. Persistence in foreign direct investment time series data is established by applying various unit root tests. The results are robust to the potential presence of structural breaks in the data. The empirical analysis shows that German outward FDI in mature manufacturing industries, with one exception, exhibits a high degree of shock persistence. The results suggest, at least for mature German industries, that the sunk costs view on shock persistency is confirmed for outward FDI. The results furnish evidence for a tentative assessment of the relationship between German public policy and FDI strategies of multinational firms.

    The natural decomposition of rubber is a very slow process due to its three-dimensional network formed by vulcanized crosslinked structures becoming extremely difficult to reprocess this material. The present work aims to study the application of gamma irradiation as devulcanization process for material reuse/recycling. The interactions of elastomers with ionizing radiation of a gamma source were investigated and the changes in physicochemical properties of the materials were evaluated. Formulations of NBR (acrylonitrile - butadiene) and EPDM (ethylene - propylene - diene terpolymer) from the rubber industry were crosslinked by conventional sulfur-based mixing. Master - batch was processed with rubber powder (industrial waste) and virgin rubber. The raw material (master batch) was irradiated in 60 Co source at doses of 50, 100, 150 kGy and dose rate of 5 kGy h -1 at room temperature. The irradiated material was incorporated in classical sulfur-based formulations. The formulations were characterized by: infrared spectroscopy (FTIR), thermal analysis (TG and DTG), tensile strength, elongation at break, hardness, abrasion resistance, rheometry and swelling. The results showed a predominance of chain scission at a dose of 50 kGy for EPDM rubber. For nitrile predominance of chain scission was observed at a dose of 100 kGy. These results show the possibility of the use of gamma radiation for the reuse/recycling of EPDM and nitrile rubbers. (author)

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    Natural rubber (NR) is the key raw material used in the manufacture of other products such as rubber band, tire and shoes. Recently, the NR is used in natural rubber glove ( NRG) manufacturing in the industrial and medical fields. This research aims to investigate the electromagnetic wave propagation and heat transfer in NRG due to heating with microwave energy within the microwave oven at a microwave frequency of 2.45 GHz. Three-dimensional model of NRG and microwave oven are considered in this work. The comparative effects of waveguide position on the electric field and temperature profile in NRG when subjected to microwave energy are discussed. The finite element method (FEM) is used to solve the transient Maxwell’s equation coupled with the transient heat transfer equation. The simulation results with computer programs are validated with experimental results. The placement of waveguides in three cases are left hand side of microwave oven, right hand side of microwave oven and left and right hand sides of microwave oven are investigated. The findings revealed that the placing the waveguide on the right side of the microwave oven gives the highest electric field and temperature profile. The values obtained provide an indication toward understanding the study of heat transfer in NRG during microwave heating in the industry.

  18. The Competitiveness of Exports from Manufacturing Industries in Croatia and Slovenia to the EU-15 Market: A Dynamic Panel Analysis

    Full Text Available It is often stated that the growth prospects of nations are closely related to patterns of competitiveness exercised by their firms and industries in the international market. Building on foundations of endogenous growth and new trade theories academics and policy-makers postulate that quality-driven competitiveness bears higher growth potential than the ability to compete in terms of prices. The transition of Central and Eastern European Countries has been characterised by movement from the latter towards the former pattern of competitiveness. This process was facilitated by the transfer of knowledge and skills through the outsourcing of production from their most important trading partners, the West European members of the European Union (EU-15 countries, which paved the way for the development of intra-industry trade. This paper explores the competitiveness of manufacturing industries from Croatia and Slovenia in the EU-15 market. Using dynamic panel analysis we find that between 2002 and 2007 producers from the two countries followed different patterns of competitiveness. While in Slovenia the quality of exports is the main determinant of EU-15 market share, the competitiveness of Croatian producers still depends on their labour costs. We also find a strong impact of intra-industry trade on the competiveness of industries from the two countries in the EU-15 market.

    Recently the number of designed modular machine was increased. The term modular machine is used to denote different types of machinery, equipment and production lines, which are created using modular elements. Modular could be both mechanic elements, and drives, as well as control systems. This method of machine design is more and more popular because it allows obtaining flexible and relatively cheap solutions. So it is worth to develop the concept of modularity in next areas of application. The advantages of modular solutions are: simplification of the structure, standardization of components, and faster assembly process of the complete machine Additional advantages, which is particularly important for manufacturers, are shorter manufacturing times, longer production series and reduced manufacturing costs. Modular designing is also the challenge for designers and the need for a new approach to the design process, to the starting process and to the exploitation process. The purpose for many manufacturers is the standardization of the components used for creating the finished products. This purpose could be realized by the application of standard modules which could be combined together in different ways to create the desired particular construction as much as possible in accordance with the order. This solution is for the producer more favorable than the construction of a large machine whose configuration must be matched to each individual order. In the ideal case each module has its own control system and the full functionality of the modular machine is obtained due to the mutual cooperation of all modules. Such a solution also requires the modular components which create the modular machine are equipped with interfaces compatible one with another to facilitate their communication. The individual components of the machine could be designed, manufactured and used independently and production management task could be divided into subtasks. They could be also
