    Full Text Available Evaluating of oils condition in agricultural machinery is very important. With monitoring and evaluating we can prevent technical and economic losses. In this paper there were monitored the liquid lubricants taken from mobile thresher New Holland CX 860. Chemical and viscosity degradation of the lubricants were evaluated. Temperature dependence dynamic viscosity was observed in the range of temperature from −10 °C to 80 °C (for all oils. Considerable temperature dependence dynamic viscosity was found and demonstrated in case of all samples, which is in accordance with theoretical assumptions and literature data. Mathematical models were developed and tested. Temperature dependence dynamic viscosity was modeled using a polynomial 6th degree. The proposed models can be used for prediction of flow behavior of oils.

    Full Text Available We need to produce enough healthy and cheap food as well as to preserve the ecologic equilibrium. This can be achived by using modern machinery and up- to-date knowledge and technology. Agricultural machinery, in which 40-60% of all funds are invested, is poorly maintained and underused. The main causes for this are poor knowledge and extensive farm land fragmentation. The fact that over 140,000 tractors in Slovenia are on average 9.6 years old, i.e. that more than 80% of overall agricultural machinery is obsolete, should be a matter of serious concern. In the paper we follow tribological conditions in particular tractor assemblies. In the first part of the paper we have treated the required conditions of tractor manufacturers in Europe and primarily in Slovenia, what has served us in the final phase of the research for elaboration of the model. In this way we have got data about the presence of particular tractor types. We have separately elaborated the necessary specifications of engine lubricants, transmission, gears, hydraulics and wet breaks. We have carried out chemical and mechanical analyses of all accessible lubricants in agricultural mechanisation. The results of the new oils were coordinated with the required specifications of tractor manufacturers and so we have got such a model, that certainly meet all lubricating requirements of our tractors.

    The number of recognized accidents with fatalities during agricultural and forestry work, despite better technology and coordinated prevention and trainings, is still very high in Austria. The accident scenarios in which people are injured are very different on farms. The common causes of accidents in agriculture and forestry are the loss of control of machine, means of transport or handling equipment, hand-held tool, and object or animal, followed by slipping, stumbling and falling, breakage, bursting, splitting, slipping, fall, and collapse of material agent. In the literature, a number of studies of general (machine- and animal-related accidents) and specific (machine-related accidents) agricultural and forestry accident situations can be found that refer to different databases. From the database Data of the Austrian Workers Compensation Board (AUVA) about occupational accidents with different agricultural machinery over the period 2008-2010 in Austria, main characteristics of the accident, the victim, and the employer as well as variables on causes and circumstances by frequency and contexts of parameters were statistically analyzed by employing the chi-square test and odds ratio. The aim of the study was to determine the information content and quality of the European Statistics on Accidents at Work (ESAW) variables to evaluate safety gaps and risks as well as the accidental man-machine interaction.

    As an important approach to the realization of agricultural sustainable development, multifunctionality has become a hot spot in the field of urban agriculture. Taking 13 agricultural counties of Beijing City as the assessing units, this study selects 10 assessing index from ecological, economic and social aspects, determines the index weight using Analytic Hierarchy Process (AHP) method, and establishes an index system for the integrated agricultural function. Based on standardized data from agricultural census and remote sensing, the integrated function and multifunctionality of urban agriculture in Beijing City are assessed through the index grade mapping. The results show that agricultural counties with the highest score in ecological, economic, and social function are Yanqing, Changping, and Miyun, respectively; and the greatest disparity among those counties is economic function, followed by social and ecological function. Topography and human disturbance may be the factors that affect integrated agricultural function. The integrated agricultural function of Beijing rises at the beginning then drops later with the increase of mean slope, average altitude, and distance from the city. The whole city behaves balance among ecological, economic, and social functions at the macro level, with 8 out of the 13 counties belonging to ecology-society-economy balanced areas, while no county is dominant in only one of the three functions. On the micro scale, however, different counties have their own functional inclination: Miyun, Yanqing, Mentougou, and Fengtai are ecology-society dominant, and Tongzhou is ecology-economy dominant. The agricultural multifunctionality in Beijing City declines from the north to the south, with Pinggu having the most significant agricultural multifunctionality. The results match up well with the objective condition of Beijing's urban agriculture planning, which has proved the methodological rationality of the assessment to a certain extent.

  12. Systems and methods for autonomously controlling agricultural machinery

    Hoskinson, Reed L.; Bingham, Dennis N.; Svoboda, John M.; Hess, J. Richard

    2003-07-08

    Systems and methods for autonomously controlling agricultural machinery such as a grain combine. The operation components of a combine that function to harvest the grain have characteristics that are measured by sensors. For example, the combine speed, the fan speed, and the like can be measured. An important sensor is the grain loss sensor, which may be used to quantify the amount of grain expelled out of the combine. The grain loss sensor utilizes the fluorescence properties of the grain kernels and the plant residue to identify when the expelled plant material contains grain kernels. The sensor data, in combination with historical and current data stored in a database, is used to identify optimum operating conditions that will result in increased crop yield. After the optimum operating conditions are identified, an on-board computer can generate control signals that will adjust the operation of the components identified in the optimum operating conditions. The changes result in less grain loss and improved grain yield. Also, because new data is continually generated by the sensor, the system has the ability to continually learn such that the efficiency of the agricultural machinery is continually improved.

    Full Text Available ABSTRACT: Customer Relationship Management can be regarded as a business approach. The objective was to know the customers, meet their expectations, and thus build customer loyalty. Although, the agricultural sector makes significant economic contributions to the Brazilian market and induces sharp competition among its companies, a huge opportunity still presents itself for the diffusion and implementation of CRM in the agricultural machinery sector. This study aimed to highlight the importance of customer management, by introducing the customer relationship management (CRM concept. This is possible in the event of reselling agricultural machines, with the intention of retaining the customers and raising the profitability of these companies. It is necessary to understand CRM as more than a mere a concept or a tool. It is a business strategy, an endeavor that must be endorsed by the entire company. The concessionaire must be perceived as greater than a mere reseller. It is to be viewed rather as a problem solver, as one who offers services that are high in quality and meet client specifics.

    2016-08-01

    There is strong advocacy for agricultural machinery appropriate for smallholder farmers in South Asia. Such 'scale-appropriate' machinery can increase returns to land and labour, although the still substantial capital investment required can preclude smallholder ownership. Increasing machinery demand has resulted in relatively well-developed markets for rental services for tillage, irrigation, and post-harvest operations. Many smallholders thereby access agricultural machinery that may have otherwise been cost prohibitive to purchase through fee-for-service arrangements, though opportunity for expansion remains. To more effectively facilitate the development and investment in scale-appropriate machinery, there is a need to better understand the factors associated with agricultural machinery purchases and service provision. This paper first reviews Bangladesh's historical policy environment that facilitated the development of agricultural machinery markets. It then uses recent Bangladesh census data from 814,058 farm households to identify variables associated with the adoption of the most common smallholder agricultural machinery - irrigation pumps, threshers, and power tillers (mainly driven by two-wheel tractors). Multinomial probit model results indicate that machinery ownership is positively associated with household assets, credit availability, electrification, and road density. These findings suggest that donors and policy makers should focus not only on short-term projects to boost machinery adoption. Rather, sustained emphasis on improving physical and civil infrastructure and services, as well as assuring credit availability, is also necessary to create an enabling environment in which the adoption of scale-appropriate farm machinery is most likely.

    As the size, complexity, and speed of agricultural tractors and self-propelled machinery have increased, so have the visibility-related issues, placing significant importance on the visual skills, alertness, and reactive abilities of the operator. Rearward movement of large agricultural equipment has been identified in the literature as causing both fatalities and injuries to bystanders who were not visible to the operator and damage to both the machine and stationary objects. The addition of monitoring assistance, while not a new concept, has advanced significantly, offering agricultural machinery operators greater options for increasing their awareness of the area surrounding the machine. In this research, we attempt to (1) identify and describe the key contributors to agricultural machinery visibility issues, i.e., operator-related and machine-related factors, and (2) enumerate and evaluate the potential solutions being offered that address these factors. Enhanced operator safety and efficiency should result from a better understanding of the efforts to solve the visibility problems inherent in large tractors and self-propelled agricultural machinery.

    The aim of this study was the identification of accident scenarios and causes by analysing existing accident reports of recognized agricultural occupational accidents with tractors, self-propelled harvesting machinery and materials handling machinery from 2008 to 2010. As a result of a literature-based evaluation of past accident analyses, the narrative text analysis was chosen as an appropriate method. A narrative analysis of the text fields of accident reports that farmers used to report accidents to insurers was conducted to obtain detailed information about the scenarios and causes of accidents. This narrative analysis of reports was made the first time and yielded first insights for identifying antecedents of accidents and potential opportunities for technical based intervention. A literature and internet search was done to discuss and confirm the findings. The narrative text analysis showed that in more than one third of the accidents with tractors and materials handling machinery the vehicle rolled or tipped over. The most relevant accident scenarios with harvesting machinery were being trapped and falling down. The direct comparison of the analysed machinery categories showed that more than 10% of the accidents in each category were caused by technical faults, slippery or muddy terrain and incorrect or inappropriate operation of the vehicle. Accidents with tractors, harvesting machinery and materials handling machinery showed similarities in terms of causes, circumstances and consequences. Certain technical and communicative measures for accident prevention could be used for all three machinery categories. Nevertheless, some individual solutions for accident prevention, which suit each specific machine type, would be necessary.

    Full Text Available Recently, land use and land cover change have received increased attention, and an approach is required that can assess agricultural land use intensity on a general basis. This study demonstrated the usefulness of a tool for characterizing and assessing agricultural land use intensity in Beijing mountainous region. An emergy analysis and principal component analysis (PCA were adopted to obtain agricultural input and output intensity data. Correlation and regression analyses were used to study the relationship among land capability, agricultural input, output intensity, and agricultural system sustainability. Ultimately, the agricultural land use intensity types in the Beijing mountainous region were identified through a cluster analysis. The results produced five indices of agricultural input intensity and five indices of output intensity. Non-renewable energy was the overwhelming input, and grain, meat, eggs, and vegetables were the major outputs of the agricultural system. The results also showed that there was better natural land quality, higher input intensity, greater output intensity, and lower agricultural system sustainability. Eight types of agricultural intensity were classified and assessed, and they may be used to evaluate and monitor sustainable land use and provide baseline measurements of land use intensity for land use analyses and change detection.

    Full Text Available The wear of machines and mechanisms after rubbing is a major concern. The costs of manufacturing and restoration parts for agricultural machinery are enormous such as the trunnions pinions of hydraulic pumps. Finishing treatment antifriction without abrasive (FTAA is the existing method of manufacturing and restoration, but it has disadvantages like low work efficiency and the frequent replacement of the instrument. That is why a new method of FTAA parts type ''tree'' has been developed called vibratory finishing treatment antifriction without abrasive, (VFTAA method. The study was conducted at the laboratory of the State Technical University of Kirovograd (Ukraine where turn 16K20, the profilograph-profilometer "Talysurf-5", the scanning electron microscope REM-106I, friction machine MI-1M and the stand KI-28097-02M were used respectively for machining, study of micro relief before and after the VFTAA, microstructure, wear resistance and the determination of the break-in period of parts. The results showed that the VFTAA helped reduce the roughness Ra of the samples studied by half compared to the samples processed by polishing and 1.3 times compared to those treated with the FTAA, the break-in period has been reduced four times , this leads to an increase in the life of the hydraulic pump. This technology can be recommended for manufacturing and repair of hydraulic units of agricultural machineries.

    Full Text Available Santa Catarina showed a significant increase in its fleet of agricultural machinery in the past 40 years. For the historical origins, the state experienced a strong farm household that grows in small portions of land. This small size of farms boosted the purchase of farm machinery such as small power tillers. It is estimated that in Santa Catarina there are more than 20,000 machines like these. The initial design of this machine its use is intended for operations on foot position for possessing it commands designed for the walking posture. But a large proportion of power tillers is used to transport cargo and personnel, by adapting implement that allows driving in the sitting position. This modification is incomplete because it does not allow the installation of steering wheel. Thus the inadequacy of command increases the difficulty in driving the vehicle and may potentiate human error, leading to the accident. To compare the usability and rate of errors in triggering commands power tiller and tractors, the work used two methods: analysis uses the model Usa-Design (U-D© and usability testing. A panel was positioned in front of the two agricultural machines simulated obstacles appearing on the right or left side of operator, in a position to rise or fall, and observed the reaction to the same stimulus. A sample of 53 volunteers showed that for all groups (experience levels the error was greater for the  power tiller. The tractor had 5.7 % error while the power tiller this value was 49.1 %. The results found by U-D© model was similar with the found in the test and pointed out serious deficiencies in functional and safety aspects of power tiller.

    Full Text Available Agricultural and transport equipment is ideally suited to use hydraulic oils. After engine oils, hydraulic fluids are the second most important group of lubricants. More than 85 % of these materials are currently mineral oil-based. In view of their high ecotoxicity and low biodegradability, mineral oil-based lubricants constitute a considerable threat to the environment. In contrast, most hydraulic fluids based on plant oils have a low environmental impact and are completely biodegradable. Moreover, lubricants based on plant oils display excellent tribological properties and generally have very high viscosity indices and flash points. For this reason, therefore, particularly soybean, sunflower and rapeseed seem to possess the relevant properties as a potential hydraulic fluid. There are several tribotechnical methods how to assess the current technical state of used lubricants (viscosity, water content, flash point, acidity. One of the modern methods how to detect wear particles is LaserNet Fines, which is a suitable technique for machine condition monitoring. The ageing of test oils is analysed by the Fourier transform infrared spectroscopy (FT-IR; for determining anti-wear properties of hydraulic oils, the standard STN EN ISO 20623:2004 indicates 1 hour under an applied load of 150 N. The objective of the paper is to show the description and examples of modern tribotechnical methods used for determination of the technical state of used biolubricants utilized in agriculture and transport machinery.

    2016-03-01

    Full Text Available The interest in environmental assessments about agricultural processes is fast growing and asking for new tools for accurate impact evaluations. The methodology commonly used to go through these studies is the life cycle assessment, of which the inventory phase (life cycle inventory, LCI is an essential step. For studies focusing on agricultural productions, the completion of LCI is particularly complex: taking into account the pedo-climatic and mechanical operative variability is evidently difficult. However, the prediction of the environmental impact of mechanical operations caused by the agricultural sector is essential to quantify the impact categories for which it is responsible. A new tool, ENVIAM, was developed to complete LCI to guarantee the availability of local data that describe the mechanical and pedo-climatic conditions occurring in the Po Valley area and widely applicable as well. It calculates mechanical power requests, directly consumed inputs (i.e., fuel, lubricant and material consumption of a productive system by taking into account soil texture, specific machinery operations and coupling solutions as defined by the user. A subdivision of working time and defined engine load have been considered to calculate fuel consumption; with regard to outputs, exhaust gases emissions from internal combustion engines have been assessed by evaluating the emissive stages of belonging as stated by the EU Directive. A case study was also performed to highlight the differences that occur when an analysis is fulfilled in a context with features different from the average, and resulted in significant variations for the inventory. In more details, a comparison was carried out both with Ecoinvent database and within ENVIAM. With regard to fuel consumption, by changing the soil texture, the analysis showed a range between 64%-184% for sandy and clay soils, respectively, if compared with medium texture ones. With this tool, local contexts defined

    2015-12-01

    Full Text Available Beijing is one of the most water-stressed regions in the world. Reducing agricultural water use has long been the basis of local policy for sustainable water use. In this article, the potential to reduce the life cycle (cradle to gate water footprints of wheat and maize that contribute to 94% of the local cereal production was assessed. Following ISO 14046, consumptive and degradative water use for the wheat-maize rotation system was modeled under different irrigation and nitrogen (N application options. Reducing irrigation water volume by 33.3% compared to current practice did not cause a significant yield decline, but the water scarcity footprint and water eutrophication footprint were decreased by 27.5% and 23.9%, respectively. Similarly, reducing the N application rate by 33.3% from current practice did not cause a significant yield decline, but led to a 52.3% reduction in water eutrophication footprint while maintaining a similar water scarcity footprint. These results demonstrate that improving water and fertilizer management has great potential for reducing the crop water footprints at the farm scale. This situation in Beijing is likely to be representative of the challenge facing many of the water-stressed regions in China, where a sustainable means of agricultural production must be found.

    2013-09-01

    Full Text Available Roll-Over Protective Structure (ROPS represents the state of art for the driver’s protection in case of tractors roll-over. Despite their real risk of overturning, the ROPS approach for the Self-Propelled agricultural Machinery (SPM is quite recent. Due to the several SPM categories available on the market, characterized by very different mass, dimension and working functions, the fitting of a ROPS and consequently the ascertainment of its protection level is quite complicated. SPM could be preliminarily divided into at least two categories: - large SPM: combine, forage, potato, sugar-beet and grape harvesters; sprayer; etc.; - small SPM: ride-on tractor, mower, comb side-delivery rake, etc. The most followed approach at present is to check preliminarily the overturning behavior of the SPM considering its longitudinal and lateral stability; if a real risk of overturning is ascertained, in order to minimize the likelihood of driver’s injury the manufacturer often installs a ROPS. The consequent need is to provide some test criteria of them. Sprayers between large SPM, and comb side-delivery rake between small SPM were the machine types on which ROPS were tested, adopting in both cases the procedure provided by Code 4 issued by the Organization for Economic and Cooperation Development (OECD, dedicated to ROPS fitted on conventional agricultural and forestry tractors. Notwithstanding the very different dimensions of these two SPM, this standard was selected considering the predictable roll-over behavior, also in relation with the front and rear track values. On the 4950 kg mass sprayer was fitted a closed cab, while on the 690 kg mass comb side-delivery rakes a 3-pillars frame was applied. In both cases the response of the tests was positive, so indicating a general suitability of OECD Code 4 to assure a ROPS good driver’s protection level in case of overturning. On the other hand, to ascertain more in detail the roll-over behavior of the SPM

    Full Text Available The success or failure of operating a rainwater harvesting system (RWH depends on both technological and non-technological factors. The importance of non-technological factors in attaining sustainable RWH operation is rarely emphasized. This study aims to assess the contribution of non-technological factors through determining decisive factors involved in the use of RWHs for agriculture irrigation in Beijing. The RWHs for agriculture irrigation in Beijing are not operating as well as expected. If the decisive factors are identified to be non-technological, the significance of non-technological factors will be highlighted. Firstly, 10 impact factors comprising non-technological and technological factors are selected according to both a literature review and interviews with RWH managers. Following this, through an artificial data mining method, rough set analysis, the decisive factors are identified. Results show that two non-technological factors, “doubts about rainwater quality” and “the availability of groundwater” determine whether these systems will continue or cease RWH operation in Beijing. It is, thus, considered necessary to improve public confidence in and motivation on using rainwater for agriculture irrigation, as this is the main obstacle in the sustainable and successful operation of RWHs. Through a case study of RWHs in Beijing, the study verifies the importance of acknowledging non-technological factors to achieve sustainable water management and considers that such factors should receive more attention by decision makers and researchers.

    Phosphorus (P) in agricultural ecosystems is an essential and limited element for plants and microorganisms. However, environmental problems caused by P accumulation as well as by P loss have become more and more serious. Oxygen isotopes of phosphate can trace the sources, migration, and transformation of P in agricultural soils. In order to use the isotopes of phosphate oxygen, appropriate extraction and purification methods for inorganic phosphate from soils are necessary. Here, we combined two different methods to analyze the oxygen isotopic composition of inorganic phosphate (δ(18)OP) from chemical fertilizers and different fractions (Milli-Q water, 0.5 mol L(-1) NaHCO3 (pH = 8.5), 0.1 mol L(-1) NaOH and 1 mol L(-1) HCl) of agricultural soils from the Beijing area. The δ(18)OP results of the water extracts and NaHCO3 extracts in most samples were close to the calculated equilibrium value. These phenomena can be explained by rapid P cycling in soils and the influence of chemical fertilizers. The δ(18)OP value of the water extracts and NaHCO3 extracts in some soil samples below the equilibrium value may be caused by the hydrolysis of organic P fractions mediated by extracellular enzymes. The δ(18)OP values of the NaOH extracts were above the calculated equilibrium value reflecting the balance state between microbial uptake of phosphate and the release of intracellular phosphate back to the soil. The HCl extracts with the lowest δ(18)OP values and highest phosphate concentrations indicated that the HCl fraction was affected by microbial activity. Hence, these δ(18)Op values likely reflected the oxygen isotopic values of the parent materials. The results suggested that phosphate oxygen isotope analyses could be an effective tool in order to trace phosphate sources, transformation processes, and its utilization by microorganisms in agricultural soils.

    Full Text Available The research reported here sought to more fully understand the types and causative factors of injury/fatality incidents resulting from the rearward-movement of tractors and other self-propelled agricultural machinery, with the view that such findings might lead to the development, improvement, and/or better utilization of safety procedures, design principles, and technologies that would prevent—or at least markedly reduce—their occurrence. Thus, the scope of this study focused only on rearward-travel (not mechanical malfunction incidents, and principally on agricultural equipment (although cases involving similar equipment in industrial or construction settings were also drawn upon. Applying these two criteria, a search of published and online sources uncovered more than 100 documented cases, 35 of which could clearly be identified as rearward-movement incidents, of which 28 (80% were fatal. Each of these 35 cases were then assessed, based on the type of machine, type of worksite, and type/description of incident (i.e., ‘scenario’, which fell into one of three distinct categories or classifications—(1 co-worker run over/crushed/otherwise injured because operator loses visual contact with co-worker; (2 bystander run over/crushed/otherwise injured because operator is unaware of bystander’s presence; and (3 operator run over/crushed/otherwise injured because operator loses visual contact with, or is unaware of, a stationary object or a hazard. Then, from each scenario, a representative incident (i.e., case study was selected for a more in-depth analysis. The collective findings, from these three case studies and all 35 machinery rearward-movement incidents, were as follows: (1 The ‘victim’ could be the machine operator as well as a co-worker or a bystander; (2 The specific site of the co-worker or bystander injury/fatality was at the base of the machine’s rear tires or tracks, at the hitching point, or behind a towed implement; (3

    2014-09-01

    Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were analyzed in 25 background and 80 agricultural soil samples collected from 21 sites in Beijing, China. The levels of PCDD/Fs in the north agricultural soils were low (0.15-0.58 ng international toxic equivalent quantity [I-TEQ]/kg), which were comparable with those of the background soils (0.091-0.35 ng I-TEQ/kg). In the southern agricultural soils, however, concentrations were several times higher (0.27-3.3 ng I-TEQ/kg). Comparison of PCDD/Fs congener compositions between possible sources and samples indicated that agricultural soils in Beijing had not been contaminated by the 3 main PCDD/F contamination sources in China--ferrous and nonferrous metal, waste incineration, and power generation. They had, however, been slightly contaminated by the impurities of some organochlorine pesticides, such as sodium pentachlorophenate, and by open burning of biomass, vehicle exhaust, atmospheric deposition, sediment, and sewage sludge. These results have been supported by the principal components analysis.

    2015-12-01

    Full Text Available Material and technical resources form a large part of the costs in agricultural production and determine the level of intensity of agriculture, productivity and competitiveness of the industry. The most important role in agricultural production is played by transport operation, from productivity and quality of which directly depends the volume and the grade of final products. More preferable is tractor transport, particularly for on-farm transport, taking into account the impact of navigation systems on the ground. Continuous growth in the saturation of tractors carried out around the world, improves the performance of tractor transport aggregate by increasing their capacity and speed, either on the road or in the field. However, if you increase the saturation of tractors, it encounters problems related to the deterioration of the controllability of the tractor and transport unit. The reduced controllability leads to an increase of damage to transported agricultural products owing to increased oscillatory processes in the system of "road – trailer – tractor – operator" when driving on-farm trails, deteriorating the smoothness and braking properties. Especially sharp these questions relate to transportation of easy-to-damage agricultural products at farm transportation. The feature of data traffic lies in the sharp drop in grade products (products receive numerous mechanical damages, deteriorating its quality, and lose marketability and accordingly reduced its cost. Influence on fruit and vegetable products of unfavorable factors can lead not only to a dramatic loss of quality at the time of transportation, but also reduce the resistance during further storage. To solve the problems emerging when increasing the saturation of tractors, we have proposed devices, allowing reducing negative impact on the production of elevated oscillatory processes, to increase the permeability and straightness of movement of tractor-transport unit

    2017-04-01

    Several soil-pressure-models deal with the impact of agricultural machines on soils. In many cases, these models were used for single spots and consider a static machine configuration. Therefore, a statement about the spatial distribution of soil compaction risk for entire working processes is limited. The aim of the study is the development of an application for the spatial modelling of traffic lanes from agricultural vehicles including wheel load, ground pressure and wheel passages at the field scale. The application is based on Open Source software, application and data formats, using python programming language. Minimum input parameters are GPS-positions, vehicles and tires (producer and model) and the tire inflation pressure. Five working processes were distinguished: soil tillage, manuring, plant protection, sowing and harvest. Currently, two different models (Diserens 2009, Rücknagel et al. 2015) were implemented to calculate the soil pressure. The application was tested at a study site in Lower Saxony, Germany. Since 2015, field traffic were recorded by RTK-GPS and used machine set ups were noted. Using these input information the traffic lanes, wheel load and soil pressure were calculated for all working processes. For instance, the maize harvest in 2016 with a crop chopper and one transport vehicle crossed about 55 % of the total field area. At some places the machines rolled over up to 46 times. Approximately 35 % of the total area was affected by wheel loads over 7 tons and soil pressures between 163 and 193 kPa. With the information about the spatial distribution of wheel passages, wheel load and soil pressure it is possible to identify hot spots of intensive field traffic. Additionally, the use of the application enables the analysis of soil compaction risk induced by agricultural machines for long- and short-term periods.

    Full Text Available In the new agricultural scenarios, the interaction between autonomous tractors and a human operator is important when they jointly perform a task. Obtaining and exchanging accurate localization information between autonomous tractors and the human operator, working as a team, is a critical to maintaining safety, synchronization, and efficiency during the execution of a mission. An advanced localization system for both entities involved in the joint work, i.e., the autonomous tractors and the human operator, provides a basis for meeting the task requirements. In this paper, different localization techniques for a human operator and an autonomous tractor in a field environment were tested. First, we compared the localization performances of two global navigation satellite systems’ (GNSS receivers carried by the human operator: (1 an internal GNSS receiver built into a handheld device; and (2 an external DGNSS receiver with centimeter-level accuracy. To investigate autonomous tractor localization, a real-time kinematic (RTK-based localization system installed on autonomous tractor developed for agricultural applications was evaluated. Finally, a hybrid localization approach, which combines distance estimates obtained using a wireless scheme with the position of an autonomous tractor obtained using an RTK-GNSS system, is proposed. The hybrid solution is intended for user localization in unstructured environments in which the GNSS signal is obstructed. The hybrid localization approach has two components: (1 a localization algorithm based on the received signal strength indication (RSSI from the wireless environment; and (2 the acquisition of the tractor RTK coordinates when the human operator is near the tractor. In five RSSI tests, the best result achieved was an average localization error of 4 m. In tests of real-time position correction between rows, RMS error of 2.4 cm demonstrated that the passes were straight, as was desired for the

    The absolute position of the sensor with respect to identifying the coordinate system is estimated based on identifying the azimuth angle for agricultural machinery full visual positioning system. The positioning algorithm was a key for the omnidirectional vision positioning system. A novel agricultural machinery positioning system was developed based on an omnidirectional vision and four or less than four artificial landmarks utilizing abundant imaging information and unchangeable directional angle for spatial point and imaging point. The positioning system has preferable features for agricultural machinery compared with GPS because of the simpler structures, higher precision, better adaptability and able to work in the night. Four artificial landmarks are built on the four corners of the enclosing rectangle around the working area. The estimated position is calculated according to the circumferential theorem and geometric transformation based on the direction angles of the landmarks with the principal point of camera. The algorithms mainly included the imaging system calibration, noise elimination, landmarks’features extraction and position estimation. Considering the noise of environment or some light obstacles, one or more of four landmarks’features extractions may be defeated. The algorithms of four landmarks detection and three landmarks detection to estimate sensor position were studied. First, the coloured landmark pixels beyond the threshold are extracted as a small area and the center of gravity is calculated for the extracted small area representing the position of one landmark. Then, the position of four representative landmarks is obtained and the four directional angles of the landmarks are estimated using only one omnidirectional image. Sensor position is able to be estimated using the center of gravity of the four intersections formed by four arcs according to geometric transformation based on the four directional angles of the extracted four

    Reviewing the development history of metropolitan agriculture is the prerequisite for sustainable agricultural development and the formulation of land consolidation strategies in metropolitan areas. Since economic reforms in 1980s, the agricultural structure has been progressively adjusted under a market-oriented development mode. Production and economic resources have been transferred to other departments with higher economic benefits. The percentage of the employment structure in the primary, secondary, and tertiary industries has changed from 28.3:40.1:31.6 (in 1978) to 6.4: 21.1:72.4 (in 2008). Because of urban sprawl,agricultural sown areas reduced from 69.1 × 104ha to 32.2× 104ha from 1978 to 2008. However, grain crops and vegetables are always the dominant parts of local agriculture. With reduction in cultivated land and marginal productivity, incomes from the primary industry contributed decreasingly to farmers' revenue. With rising of living standards of people, people would pay more attention to environmental and ecological protection, as well as scenery enjoying. The main function of farmland has been transferred to ecological protection and sightseeing in metropolis areas. Taking agricultural land as the green space would be greatly helpful in multi-purpose uses of cultivated land. Adequate utilization of agricultural landscape with its ecological functions would also be a promising way to make urban areas more comfortable for living. On the basis of the comparative advantage theory, the present study analyzes the comprehensive comparative advantage of agriculture between different counties in Beijing Municipality from 1985 to 2005.Results indicate that the comparative advantage of agriculture has shifted into the outer parts of Beijing. For achieving the multi-function of agriculture, the spatial arrangement of land consolidation should be in accord with environment protection and scenery requirement.

Futhermore, with the quick increase of numbers of such diesel engines and their wider and wider application, it becomes more and more difficult to evaluate the total exhaust emissions from such sources. To solve the said problem, the present authors have put forward a model for estimating such emissions. In proceeding with our research, we have first of all normalized the emission factors of the fuel consumption and evaluated the total activity and the total fuel consumption of the farm machinery. As a result, we have determined that the emission factors of the farm-use diesel machinery in Beijing were 9.38 g· kg

    Full Text Available This paper looks into the possibilities that local development strategies inspired in the reality of European countries may be applied to peripheral countries such as Argentina. A difference is made between a global/national context and a local one. the analysis takes into account geographical, sociological and economic discourses which, considering the Italian and French experience, among others, relativize the national scale as the axis of analysis and focus on the local birth as scale of reference. The agricultural machinery businesses of Las Parejas, in the province of Santa Fe, are used to exemplify how a medium-sized city can generate associative projects which help actors to deal with the context, though this is still a business performance and local productive networks life variable.

    对我国农用运输车的概念作了进一步深入阐述,并在科学理论基础上,提出了农用运输车应具备的特色技术,特别提出对农用运输车的越野性能要有足够的重视。%Since the model of four-wheeled farm transport vehicle was selected by the government 14 years ago, it has not been satisfied with its market profits. For example, it shared only 16% of a total production of three million farm transport vehicles in 1998, which was farless than that of the three-wheeled model. Especially, there is a trend recently for the four-wheeled farm transport vehicles to follow the concept of an automobile, which makes its price higher and even a poorer market in China.   The paper gives a detailed discussion concerned with the concept and design principle of a farm transporter in China and points out the technical features it should possess, such as low speed under the full load, climbing property at heavy load, large tire size, axial load distribution for the stability, big driven force of an overloaded vehicle and so on. Besides those, a special attention should be paid to their off-road capability.

    To develop the low-carbon agriculture in modern city is essential to reduce greenhouse gas emission, which is one of the important component parts to realize national macroscopical strategy. In this paper, we propose the definition and characteristics for the low-carbon agriculture. It is regarded as a modern agriculture system with low input, high productivity, low ( i. e. , negative) carbon and being eco-friendly, which can be established through technology improvement and system creation. The low-carbon agriculture has four characteristics, namely open system, integrated technology, life-cycle management and process safety. Using the balanced method of carbon source/sink, we analyze the situation of agriculture in Beijing. The results indicate that the carbon source and carbon sink are 10-20 TgCO2eq · a-1 and 10.23 -14. 16 TgCO2eq · a-1 respectively,the carbon source might keep a stable level, and carbon sink has a great potential. According to the specific eco-characteristics and the future position of agriculture in Beijing, the development of low-carbon agriculture at a technical level should be focused on the soil carbon sink and breeding techniques, which is closely related to cultivation system and greenhouse emission. At the institutional level, we should establish a mechanism that can adjust and optimize the patterns of agricultural production, and development of cleaner production mechanism, ecological compensation mechanism, agricultural market access mechanism and integrated regulating mechanism should also be taken into account. For the prospect of the low-carbon agriculture in Beijing, the preliminary results indicate that the amount of carbon sink potential might reach to 20 - 30 TgCO2 eq · a-l, and the direct carbon source might decrease to 4 -5 TgCO2eq · a-1 In conclusion, through the application of the low-carbon agriculture in Beijing, the agricultural carbon source might be offset, and total carbon dioxide emission from greenhouse gases

    The occurrence of ∑HCHs, ∑DDTs, protozoa abundance and their community structure in surface soils of orchards, vegetable lands, and barren lands in northern west outskirts of Beijing were detected in order to investigate the protozoa responses to low dose organic chlorinated Pesticides (OCPs) after long-term field-based exposure. Significant differences in total concentrations of HCHs and DDTs were found among the three general groups ranking in decreasing order of concentration from orchard>vegetable lands >barren lands. Ciliate was the rare group in surface soils of all the sampling groups. The abundance of flagellate, ciliate, and amoebae in vegetable soils were significantly higher than those in orchard soils. The abundance of all the taxa of protozoa was strongly negative correlated with the residue level of ∑HCHs and ∑DDTs (Pprotozoa abundance was shown in both the orchard and the barren soils. This field study demonstrated a considerable long-term impact of the OCPs residue on the abundance of protozoa in soils, and that the abundance of soil protozoa was much more influenced by land use type in association with different soil properties.

    Kjeldsen, M.

    1996-11-01

    The main purpose of this doctoral thesis on cavitation in hydraulic machinery is to change focus towards the coupling of non-stationary flow phenomena and cavitation. It is argued that, in addition to turbulence, superimposed sound pressure fluctuations can have a major impact on cavitation and lead to particularly severe erosion. For the design of hydraulic devices this finding may indicate how to further limit the cavitation problems. Chapter 1 reviews cavitation in general in the context of hydraulic machinery, emphasizing the initial cavitation event and the role of the water quality. Chapter 2 discusses the existence of pressure fluctuations for situations common in such machinery. Chapter 3 on cavitation dynamics presents an algorithm for calculating the nucleation of a cavity cluster. Chapter 4 describes the equipment used in this work. 53 refs., 55 figs.,10 tabs.

    Full Text Available The approach of material embodiment in agricultural production systems is important because it determines the convergence of inputs (indirectly, the natural resources to the field. Additionally, material flow is the basis for both environmental (energy analysis, emergy synthesis, life-cycle analysis and carbon inventories and economical analyses. Since different materials cannot compose a single index, generally these flows are not shown, making comparisons among approaches difficult. Another aspect that makes comparisons difficult is the definition of the boundary of the studied system. If these boundaries differ, results will also be different, hiding actual distinctions among systems. The present study aims to suggest an arrangement of existing models to determine material flow in agricultural production systems. The following steps were considered: i the adoption of a diagram language to represent the analyzed system; ii determination of the material flow for directly applied inputs; iii determination of the material flow for indirectly applied inputs, which included: determination of the effective field capacity; fuel consumption; machinery depreciation; and labor. Data on fuel consumption were compared with the models presented. The best model applied was a fixed parameter based on engine power (0.163 L kW-1 h-1. The determination of the material flow for maize silage production presented similar results as those obtained in regional databases.A abordagem da incorporação material em sistemas agrícolas é importante, pois determina a convergência de insumos (indiretamente, de recursos naturais no campo.

    China is a large agricultural country, and the tractor is the main agricultural machinery; therefore, its automation degree can represent the level of agricultural mechanization in a country to a large extent. As the core driving part of the tractor, clutch is directly connected with the engine, transfers power by the friction torque of master-slave movable sheets, and realizes the working state of the vehicle powertrain system through the clutch engaging and disengaging. Clutch reliability is worth attention due to that the quality of its separation and bonding directly affects the quality and safety of vehicle shift, however, current study on the clutch is mainly in terms of engagement and gear shifting impact, more emphasis is on the research of the individual parts, and there are few attentions in the analysis of the assembly characteristics for the clutch. The reliability of the clutch assembly cannot be separated from the interaction between the components. Gray relational theory is used to explore the actual movement laws, and mainly according to the known information, it uses the sequence operator to further extract valuable information to realize the correct description and effective monitoring of system behavior and evolution law. After the investigation of the actual working conditions of the clutch, the structural failure of the clutch is mainly attributed to 20 factors. Among the verified factors, strength, stiffness, damping, and heat resistance of key parts of clutch are selected as the research targets. In order to analyze the influence of the components on the clutch, the three-dimensional model of the clutch is established in UG (Epigraphics NX, UG)according to the specific structure of the clutch. Considering the failure form, production process, test engineering and customer feedback of clutch, the performance index of the clutch is treated according to the mathematical model of the subjective comprehensive evaluation, the clutch grey

Among the four habitats, orchard had the highest α-diversity of carabid assemblage, followed by woodland and maize field, and peanut field had the lowest one. The species composition of the assemblage in woodland, peanut field, and orchard had evident difference, but was similar to that in maize field to some extent. The number of the individuals of predatory and omnivorous carabid sub-assemblages was larger in orchard, and the predatory sub-assemblage presented more distinct difference in its species turnover rate than the omnivore sub-assemblage among the habitats. This study showed that low-intensively managed orchard habitat could sustain higher α-diversity of carabid assemblage than semi-natural woodland habitat, and the landscape with diversified habitats could benefit the β-diversity of carabid assemblage

    Methane sulphonate (MSA) and sulfate (SO42-), the main oxidation products of dimethyl sulfide (DMS), are the target of atmospheric chemistry study, as sulfate aerosol would have important impact on the global climate change. It is widely believed that DMS is mainly emitted from phytoplankton production in marine boundary layer (MBL), and MSA is usually used as the tracer of non-sea-salt sulfate (nss- SO42-) in marine and coastal areas (MSA/SO42- = 1/18). Many observations of MSA were in marine and coastal aerosols. To our surprise, MSA was frequently (>60%) detected in Beijing TSP, PM10, and PM2.5 aerosols, even in the samples collected during the dust storm period. The concentrations of MSA were higher than those measured in marine aerosols. Factor analysis, correlation analysis and meteorology analysis indicated that there was no obvious marine influence on Beijing aerosols. DMS from terrestrial emissions and dimethyl sulphoxide (DMSO) from industrial wastes could be the two possible precursors of MSA. Warm and low-pressure air masses and long time radiation were beneficial to the formation of MSA. Anthropogenic pollution from regional and local sources might be the dominant contributor to MSA in Beijing aerosol. This was the first report of MSA in aerosols collected in an inland site in China. This new finding would lead to the further study on the balance of sulfur in inland cities and its global biogeochemical cycle.

    <正>Nothing can compare to looking down this old city from above. Beijing’s physical growth during the last 30 years makes it difficult to appreciate the layout of the city and the relationship of each district to the city as a whole. It would be great to actually see it from the air, but the city’s airport is to the east of the built-up area and only on very clear days can the whole city stretching to the Western Hills be seen during descent. Maps of Beijing, updated with the layout of the city every year, can give a two-dimensional view of the city’s shape and particularly the development of the urban highway network. However, nothing can compare to looking down from above.

    2012-01-01

    Agricultural land use right transfer (LURT) is an important rural land reform in recent years in China. The LURT was affected by many factors, and social-economic factors were usually studied. However, the land- scape processes of LURT and the impact of regional land use types on LURT is little understood. According to the effects of LURT on landscape, LURT can be divided into two processes: land use right transfer in rural op- erating land and non-agricultural occurrence in the transferred land. Based on the two processes, this article de- fined the transferred type and non-transferred type for the land use right transfer, and non-agricultural type and agricultural type for the non-agricultural occurrence. Changping district of Beijing was took as a case, and the relationships between the regional land use types and LURT landscape processes were established with Logis- tic and Autologistic models. The results showed that urban and city land is the most important land use type to cause the occurrence of land use right transfer, meanwhile, the type also stimulated the change of agricultural use to non-agricultural use in transferred land. On the scale of historical land uses effects, the influence of these land uses was mainly reflected at the medium scale region (1-5 km) and the small scale region (0-1 km) for the occurrence of land use right transfer and the occurrence of non-agricultural uses in transferred patches respectively. Compared with traditional Logistic model, Autologistic model containing the spatial autocorrela- tion effects has higher accuracy, thusspatial autocorrelation effects cannot be ignored for the study the driven forces on LURT.%以北京市昌平区为例,将农村土地经营权流转分为流转发生及流转后土地非农化发生等两个变化过程。分别采用传统Logistic和Autologistic回归模型分析了流转发生前、后区域土地利用方式对土地流转景观过程的影响。结果显示,城镇用地是推动

    Full Text Available Statistics on the machinery performance are essential for farm managers to make better decisions. In this paper, the performance of all machineries in five sequential operations, namely bed forming, stone separation, planting, spraying and harvesting in the potato production system, were investigated during one growing season. In order to analyse and decompose the recorded GPS data into various time and distance elements for estimation of the machinery performance, an automatic GPS analysis tool was developed. The field efficiency and field capacity were estimated for each operation. Specifically, the measured average field efficiency was 71.3% for bed forming, 68.5% for stone separation, 40.3% for planting, 69.7% for spraying, and 67.4% for harvesting. The measured average field capacities were 1.46 ha/h, 0.53 ha/h, 0.47 ha/h, 10.21 ha/h, 0.51 ha/h, for the bed forming, stone separation, planting, spraying, and harvesting operations, respectively. These results deviate from the corresponding estimations calculated based on norm data from the American Society of Agricultural and Biological Engineers (ASABE. The deviations indicate that norms provided by ASABE cannot be used directly for the prediction of performance of the machinery used in this work. Moreover, the measured data of bed forming and stone separation could be used as supplementary data for the ASABE which does not provide performance norms for these two operations. The gained results can help farm managers to make better management and operational decisions that result in potential improvement in productivity and profitability as well as in potential environmental benefits.

    Full Text Available Giovanni Arrighi's Adam Smith in Beijing (ASB subverts the temporality and conceptual vocabulary employed by most writers working in a Marxist tradition. In this view, capitalism is a mode of production which eventually encompasses the entire world. Perhaps it began in England and expanded from there. Perhaps its expansion through colonial empires should be seen as part of its constitution, rather than an after effect (i.e. the perspective of Wallerstein. In any case, it eventually dominates the world and every place that is a part of it through such phenomena as, multinational corporations, wage labor, and international capital flows. The particular class relations, political systems, and international relations that held before the spread of capitalism are only of interest to the extent that they leave a residue which may be reclaimed by actors seeking to reinforce or undermine the rule of capital in particular places. For Arrighi, Chinese development neither is, nor ever was, simply “capitalist.” Rather, it was, and continues to be “Smithian,” devoted to the maintenance and expansion of a market society (the obvious irony here is that China is seen as more “Smithian” than those places which most heartily celebrate the Scottish political economist.

  5. Stochastic noise in splicing machinery.

    2009-08-01

    The number of known alternative human isoforms has been increasing steadily with the amount of available transcription data. To date, over 100 000 isoforms have been detected in EST libraries, and at least 75% of human genes have at least one alternative isoform. In this paper, we propose that most alternative splicing events are the result of noise in the splicing process. We show that the number of isoforms and their abundance can be predicted by a simple stochastic noise model that takes into account two factors: the number of introns in a gene and the expression level of a gene. The results strongly support the hypothesis that most alternative splicing is a consequence of stochastic noise in the splicing machinery, and has no functional significance. The results are also consistent with error rates tuned to ensure that an adequate level of functional product is produced and to reduce the toxic effect of accumulation of misfolding proteins. Based on simulation of sampling of virtual cDNA libraries, we estimate that error rates range from 1 to 10% depending on the number of introns and the expression level of a gene.

    The product development process (PDP, if well-structured and managed, can become a business process that directly influences the companies' competitiveness increase. The PDP in Brazilian SMEs in the agricultural machinery and implement industry Sector (AMI is little known since most publications on product development focuses on the reality of large and multinational companies, which have a quite different structure from SMEs. The purpose of this paper is to characterize and analyze the management maturity profiles of the product development process in small and medium sized Brazilian companies in the agricultural machinery and implement industry sector located in the state of São Paulo. Therefore, the addressed actions of PDP improvements in those companies can be undertaken. A survey research was conducted in 40 companies. An in loco interview was applied to the respective individual in-charge of PDP by means of a structured questionnaire. For the data analysis, descriptive statistics and the multivariate cluster analysis techniques were used. The findings indicated that the SMEs in AMIs of the state of Sao Paulo present a heterogeneous structure with respect to PDP management. Three groups of companies were identified in the sample with different maturity PDP profiles: Group I (20% of companies in the sample, Group II (50% of the sample, and Group III (30% of the sample. Differences in the management of PDP were observed, especially among companies of Group I (smallest level of PDP maturity and Group III (highest level of PDP maturity. However, despite the differences in PDP management presented in the groups of companies, according to the literature on PDP management, all groups are in the basic (initial maturity level of PDP. The identification of the maturity level, in which these companies are, can help the determination of activities that link the internal actions to improve the PDP of these companies and the proposal of specific public policies that encourage the

    Agricultural machinery is a major source of injury on farms. The importance of machinery safety practices as potential determinants of injury remains incompletely understood. We examined two such safety practices as risk factors for injury: (1) the presence of safety devices on machinery and (2) low levels of routine machinery maintenance. Our data source was the Saskatchewan Farm Injury Cohort baseline survey (n=2390 farms). Factor analysis was used to create measures of the two operational safety practices. The farm was the unit for all analyses and associations were evaluated using multiple Poisson regression models. Limited presence of safety devices on machinery during farm operations was associated with higher risks for injury (RR 1.94; 95% CI 1.13-3.33; p(trend)=0.02). Lower routine maintenance scores were associated with significantly reduced risks for injury (RR 0.54; 95% CI 0.29-0.98; p(trend)=0.05). The first finding implies that injury prevention programs require continued focus on the use of safety devices on machinery. The second finding could indicate that maintenance itself is a risk factor or that more modern equipment that requires less maintenance places the operator at lower risk. These findings provide etiological data that confirms the practical importance of operational safety practices as components of injury control strategies on farms. Copyright 2010 Elsevier Ltd.

    Agricultural land evaluation is defined as evaluating land resources suitability for crop growth and ana-lyzing the feasibility of land use for agriculture. Agricultural land evaluation system is perfected based on qualityand site of farmland in order to be accustomed to the farmland protection. This system is designed as a gradationframework which includes (1)the suitable types of farmland, (2)the suitable orders of farmland, (3)the valueclasses of farmland use, and (4)land resources units. In this paper, the evaluating unit is farmland plot which isused in town area and shown on land-use map with one to ten thousands scale. Corresponding to the differentgradation of agricultural land evaluation system, the different factors evaluating farmland are chosen. In the light of the above-mentioned agricultural land evaluation system, with Liangxiang, a town of Fang-shan District, Beijing, as an example, the operating pattern evaluating the suitable types and orders of farmlandis put forward based on GIS technique. Firstly, according to the national criteria of farmland fertility drafted byChina Ministry of Agriculture and the land evaluation framework published by FAO, the agricultural land quali-ty reference frame is established, which is composed of four kinds of factors including soil fertility, environmentcondition, engineering and management of farmland. Then farmland units which is fit to cultivation are separat-ed by "Reselect” command of PC ARC/info based on the land quality reference frame. Secondly, the selectedfarmland units are evaluated further. The farmland quality is evaluated by employing the fuzzy closeness algo-rithmic technique, and the farmland site is assessed adopting the model of factor scoring sum, then the possibili-ty and feasibility of agricultural land-use are revealed, and the prime farmland is confirmed. The data of farm-land quality factors come respectively from the datum of Fangshan soil general survey, Liangxiang topographicmap and

    Wiedemann, Nils; Pfanner, Nikolaus

    2017-03-15

    Mitochondria are essential organelles with numerous functions in cellular metabolism and homeostasis. Most of the >1,000 different mitochondrial proteins are synthesized as precursors in the cytosol and are imported into mitochondria by five transport pathways. The protein import machineries of the mitochondrial membranes and aqueous compartments reveal a remarkable variability of mechanisms for protein recognition, translocation, and sorting. The protein translocases do not operate as separate entities but are connected to each other and to machineries with functions in energetics, membrane organization, and quality control. Here, we discuss the versatility and dynamic organization of the mitochondrial protein import machineries. Elucidating the molecular mechanisms of mitochondrial protein translocation is crucial for understanding the integration of protein translocases into a large network that controls organelle biogenesis, function, and dynamics. Expected final online publication date for the Annual Review of Biochemistry Volume 86 is June 20, 2017. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    The rRNAs constitute the catalytic and structural components of the ribosome, the protein synthesis machinery of cells. The level of rRNA synthesis, mediated by Pol I (RNA polymerase I), therefore has a major impact on the life and destiny of a cell. In order to elucidate how cells achieve the stringent control of Pol I transcription, matching the supply of rRNA to demand under different cellular growth conditions, it is essential to understand the components and mechanics of the Pol I transcription machinery. In this review, we discuss: (i) the molecular composition and functions of the Pol I enzyme complex and the two main Pol I transcription factors, SL1 (selectivity factor 1) and UBF (upstream binding factor); (ii) the interplay between these factors during pre-initiation complex formation at the rDNA promoter in mammalian cells; and (iii) the cellular control of the Pol I transcription machinery.

    Full Text Available Global Positioning System (GPS has made a great evolution in different aspects of modern agricultural sectors. Today, a growing number of crop producers are using GPS and other modern electronic and computer equipments to practice Site Specific Management (SSM and precision agriculture. This technology has the potential in agricultural mechanization by providing farmers with a sophisticated tool to measure yield on much smaller scales as well as precisely determination and automatic storing of variables such as field time, working area, machine travel distance and speed, fuel consumption and yield information. This study focuses on how to interpret and process raw GPS data for operational analysis of farm machinery. Exact determinations of field activities using GPS data along with accurate measurements and records of yield provide an integrated tool to calculate field efficiency and field machine index which in turn increases machine productivity and labor saving. The results can also provide graphical tools for visualizing machine operator’s performance as well as making decision on field and machine size and selection.

  8. Wintertime Haze Formation in Beijing

    Levy Zamora, M. E.

    2015-12-01

    Recent severe haze events in China have attracted significant public attention due to the severely reduced visibility and unprecedentedly high pollutant concentrations. Particular attention has been given to the high concentrations of particulate matter with a diameter less than 2.5 microns (PM2.5), which can exceed several hundred micrograms per cubic meter over several days. During January and February of 2015, a suite of aerosol instruments was deployed in Beijing to directly measure a comprehensive set of aerosol properties, including the particle size distribution, effective density, and chemical composition. In this presentation, we will discuss the particulate matter formation mechanisms, the evolution of aerosol properties throughout the event, and how the winter formation mechanisms compare with the warmer seasons. We show that the periodic cycles of severe haze episodes in Beijing are largely driven by meteorological conditions. During haze events, stagnation typically develops as a result of a low planetary boundary layer and weak southerly wind from polluted industrial source regions. Stronger northerly winds were frequently observed during the clean period, which carry unpolluted air masses from the less populated northern mountainous areas. Nucleation consistently occurs on clean days, producing a high number concentration of nano particles. The particle mass concentration exceeding several hundred micrograms per cubic meter is attributed to the continuous size growth from the nucleation-mode particles (diameter less than 10 nm) over multiple days to produce a high concentration of larger particles (diameter greater than 100 nm). The particle chemical composition in Beijing is similar to those commonly measured in other urban centers, which is indicative of chemical constituents dominated by secondary aerosol formation. Our results reveal that the severe haze formation in Beijing during the wintertime is similar to the mechanism of haze formation

    Full Text Available Beijing Municipality, characterised by the ‘off-ground’ architecture distinguishing neo-liberal privatisation, is attempting to mitigate the damaging effects of rampant development on the social fabric, cultural heritage, and the environment by adopting sustainable urban planning. I argue that the sustainability rhetoric in the Beijing Municipality 2020 Plans functions in part as strategic metaphors masking unnamed, imminent threats to governance. In this article I diagnose four Beijing plans (Beijing 2006-2015 ‘Rail Transit Plan’ for Compact City, Beijing 2005-2020 ‘Underground Space Plan’ for Alternative Space, Beijing 2006-2020 ‘Undeveloped Area Plan’ for Ecological Responsibility, and Beijing 2006-2010 ‘Low-income Housing Plan’ for Affordability and Liveability. A diagrammatics of the plans illuminates not so much a mapping of Beijing’s future as the forms of spontaneity preoccupying the nation at this historical juncture. The Beijing 2020 plan, as city mapping more generally, discloses the imminence of ungovernable city. The fact that citizens are demanding greater authority over Beijing governance suggests that radical alterations to its urban fabric and quality of life have incited the imminent sociability that is the city.

    This paper presented computational design methods for liquid hydrogen fluid machinery for which the aerospace industry holds a particular interest. The main design points are reliability, efficiency and predictability. The methods described here were based on experience gained in the liquefied natural gas sector. The main design validation tools presented in this paper were computational fluid dynamics, computational rotordynamics, and computational stress analysis. Recent advances have made it possible to incorporate the influence of unsteady phenomena. These new design techniques make it possible to increase the reliability, efficiency and predictability of fluid machinery. A design example for an Ebara Cryodynamics multi-stage impeller/diffuser-return vane combination operating in liquefied natural gas was presented. The fluid machinery characteristics were compared for liquid hydrogen and liquefied natural gas to demonstrate the technical feasibility of industrial liquid hydrogen fluid machinery. Currently, no significant demand exists for liquid hydrogen turbomachinery except for the rocket engine industry. But the emergence of the hydrogen economy will promote the growth in liquefied natural gas and or liquid hydrogen cryogenic turbomachinery. 11 refs., 3 tabs., 6 figs.

    As the demands on limited water resources intensify, concerns are being raised about the human carrying capacity of these resources. However, few researchers have studied the carrying capacity of regional water resources. Beijing, the second-largest city in China, faces a critical water shortage that will limit the city's future development. We developed a method to quantify the carrying capacity of Beijing's water resources by considering water-use structures based on the proportions of water used for agricultural, industrial, and domestic purposes. We defined a reference structure as 45:22:33 (% of total, respectively), an optimized structure as 40:20:40, and an ideal structure as 50:15:35. We also considered four domestic water quotas: 55, 75, 95, and 115 m3/(person x yr). The urban carrying capacity of 10-12 million was closest to Beijing's actual 2003 population for all three water-use structures with urban domestic water use of 75 m3/(person x yr). However, after accounting for our underlying assumptions, the adjusted carrying capacity is closer to 5-6 million. Thus, Beijing's population in 2003 was almost twice the adjusted carrying capacity. Based on this result, we discussed the ecological and environmental problems created by Beijing's excessive population and propose measures to mitigate these problems.

    2001-01-01

    The 29th Olympic Game will be held in Beijing in 2008. It will be a green game to promote sustainable development of men,cities and regions through ecological development advocating "man and nature be in one". "Eco" here means a process, a driving force, an action, a culture and a kind of vitality leading to sustainable development. It is a mechanism embodying the Olympic spirit ofcompetition, cooperation and self-reliance. The paper explained the ecological significance, connotation and objectives of Beijing Green Olympic Game. Ten major ecological heritages of Beijing have been investigated including ecologically sound landscape, culture, trnsportation, physical exercise, health care, sanitation, food, family relationship, agriculture, and human ecological totality. To preserve or restore the above mentioned old tradition, a green Olympic action plan has been made out in Beijing initiated by NGOs, supported by entrepreneurs and coordinated by government agencies. Four kinds of eco-engineering have been planned for blue sky, cleanwater, green land and eco-city development. The demonstration role of Beijing Green Olympic Game to developing regions and countries is also discussed.

    2008-01-01

    This paper considers a problem of optimal preventive maintenance and replacement schedule ofequipment devoted to extracting resources from known deposits. Typical examples are oil drills, mine shovels, etc. At most one replacement of the existing machinery by a new one is allowed. The problem is formulated as an optimal control problem subject to the state constraint that the remaining deposit at any given time is nonnegative. We show that the optimal preventive maintenance, production rates, and the replacement and salvage times of the existing machinery and the new one, if required, can be obtained by solving sequentially a series of free-end-point optimal control problems. Moreover, an algorithm based on this result is developed and used to solve two illustrative examples.

  18. The Autophagic Machinery in Enterovirus Infection

    Directory of Open Access Journals (Sweden)

    Jeffrey K. F. Lai

    2016-01-01

    Full Text Available The Enterovirus genus of the Picornaviridae family comprises many important human pathogens, including polioviruses, rhinovirus, enterovirus A71, and enterovirus D68. They cause a wide variety of diseases, ranging from mild to severe life-threatening diseases. Currently, no effective vaccine is available against enteroviruses except for poliovirus. Enteroviruses subvert the autophagic machinery to benefit their assembly, maturation, and exit from host. Some enteroviruses spread between cells via a process described as autophagosome-mediated exit without lysis (AWOL. The early and late phases of autophagy are regulated through various lipids and their metabolizing enzymes. Some of these lipids and enzymes are specifically regulated by enteroviruses. In the present review, we summarize the current understanding of the regulation of autophagic machinery by enteroviruses, and provide updates on recent developments in this field.

  20. The exportomer: the peroxisomal receptor export machinery.

    Science.gov (United States)

    Platta, Harald W; Hagen, Stefanie; Erdmann, Ralf

    2013-04-01

    Peroxisomes constitute a dynamic compartment of almost all eukaryotic cells. Depending on environmental changes and cellular demands peroxisomes can acquire diverse metabolic roles. The compartmentalization of peroxisomal matrix enzymes is a prerequisite to carry out their physiologic function. The matrix proteins are synthesized on free ribosomes in the cytosol and are ferried to the peroxisomal membrane by specific soluble receptors. Subsequent to cargo release into the peroxisomal matrix, the receptors are exported back to the cytosol to facilitate further rounds of matrix protein import. This dislocation step is accomplished by a remarkable machinery, which comprises enzymes required for the ubiquitination as well as the ATP-dependent extraction of the receptor from the membrane. Interestingly, receptor ubiquitination and dislocation are the only known energy-dependent steps in the peroxisomal matrix protein import process. The current view is that the export machinery of the receptors might function as molecular motor not only in the dislocation of the receptors but also in the import step of peroxisomal matrix protein by coupling ATP-dependent removal of the peroxisomal import receptor with cargo translocation into the organelle. In this review we will focus on the architecture and function of the peroxisomal receptor export machinery, the peroxisomal exportomer.

    2012-12-01

    Plastids divide by constriction of the plastid-dividing (PD) machinery, which encircles the division site. The PD machinery consists of the stromal inner machinery which includes the inner PD and filamenting temperature-sensitive mutant Z (FtsZ) rings and the cytosolic outer machinery which includes the outer PD and dynamin rings. The major constituent of the PD machinery is the outer PD ring, which consists of a bundle of polyglucan filaments. In addition, recent proteomic studies suggest that the PD machinery contains additional proteins that have not been characterized. The PD machinery forms from the inside to the outside of the plastid. The constriction seems to occur by sliding of the polyglucan filaments of the outer PD ring, aided by dynamin. The final fission of the plastid is probably promoted by the 'pinchase' activity of dynamin.

Since modern machines are complex and the amount of data to be interpreted is huge, we need precise and fast methods in order to arrive at the best recommendations to prevent catastrophic failure and to prolong the life of the equipment. In the present work using vibration characteristics of a rotor-bearing system, the condition of a rotating machinery (electrical rotor is predicted using an off-line expert system. The analysis of the problem is carried out in an Object Oriented Programming (OOP framework using the finite element method. The expert system which is also developed in an OOP paradigm gives the type of the malfunctions, suggestions and recommendations. The system is implemented in C++.

  19. Evolution of the chloroplast division machinery

    Institute of Scientific and Technical Information of China (English)

    Hongbo GAO; Fuli GAO

    2011-01-01

    Chloroplasts are photosynthetic organelles derived from endosymbiotic cyanobacteria during evolution.Dramatic changes occurred during the process of the formation and evolution of chloroplasts,including the large-scale gene transfer from chloroplast to nucleus.However,there are still many essential characters remaining.For the chloroplast division machinery,FtsZ proteins,Ftn2,SulA and part of the division site positioning system- MinD and MinE are still conserved.New or at least partially new proteins,such as FtsZ family proteins FtsZl and ARC3,ARC6H,ARC5,PDV1,PDV2 and MCD1,were introduced for the division of chloroplasts during evolution.Some bacterial cell division proteins,such as FtsA,MreB,Ftn6,FtsW and Ftsl,probably lost their function or were gradually lost.Thus,the chloroplast division machinery is a dynamically evolving structure with both conservation and innovation.

    Full Text Available In the process of maintenance management of machinery and devices there is necessity to keep in the mind "construction technologicity” (ability of construction technology. This term is used in evaluating of machinery construction, their groups and components in terms of production. The aim of management and planning maintenance of machinery is the failure-free operation in the application process. The range of machinery maintenance machines from routine one and inspection to general repairs is important to organize in a way to prevent unplanned idle time and failures or very likely to accidents.

  4. Genomic diversity among Beijing and non-Beijing Mycobacterium tuberculosis isolates from Myanmar.

    Directory of Open Access Journals (Sweden)

    Ruth Stavrum

    Full Text Available BACKGROUND: The Beijing family of Mycobacterium tuberculosis is dominant in countries in East Asia. Genomic polymorphisms are a source of diversity within the M. tuberculosis genome and may account for the variation of virulence among M. tuberculosis isolates. Till date there are no studies that have examined the genomic composition of M. tuberculosis isolates from the high TB-burden country, Myanmar. METHODOLOGY/PRINCIPLE FINDINGS: Twenty-two M. tuberculosis isolates from Myanmar were screened on whole-genome arrays containing genes from M. tuberculosis H37Rv, M. tuberculosis CDC1551 and M. bovis AF22197. Screening identified 198 deletions or extra regions in the clinical isolates compared to H37Rv. Twenty-two regions differentiated between Beijing and non-Beijing isolates and were verified by PCR on an additional 40 isolates. Six regions (Rv0071-0074 [RD105], Rv1572-1576c [RD149], Rv1585c-1587c [RD149], MT1798-Rv1755c [RD152], Rv1761c [RD152] and Rv0279c were deleted in Beijing isolates, of which 4 (Rv1572-1576c, Rv1585c-1587c, MT1798-Rv1755c and Rv1761c were variably deleted among ST42 isolates, indicating a closer relationship between the Beijing and ST42 lineages. The TbD1 region, Mb1582-Mb1583 was deleted in Beijing and ST42 isolates. One M. bovis gene of unknown function, Mb3184c was present in all isolates, except 11 of 13 ST42 isolates. The CDC1551 gene, MT1360 coding for a putative adenylate cyclase, was present in all Beijing and ST42 isolates (except 1. The pks15/1 gene, coding for a putative virulence factor, was intact in all Beijing and non-Beijing isolates, except in ST42 and ST53 isolates. CONCLUSION: This study describes previously unreported deletions/extra regions in Beijing and non-Beijing M. tuberculosis isolates. The modern and highly frequent ST42 lineage showed a closer relationship to the hypervirulent Beijing lineage than to the ancient non-Beijing lineages. The pks15/1 gene was disrupted only in modern non-Beijing

  5. Analysis of Input and Output of China’s Agriculture Based on Canonical Correlation

    2011-01-01

    I select effective irrigated area, consumption of agricultural chemical fertilizer, electricity consumed in rural areas, and total power of agricultural machinery as input variables of China’s agriculture; I select grain, bean, tobacco, oil-bearing crop and fruit as output variables of China’s agriculture. By using the data of China Statistical Yearbook in 2010, based on the analysis method of canonical correlation, I conduct research on the input and output of China’s agriculture. The results show that consumption of chemical fertilizer has the biggest impact on the agricultural output of China, followed by the input of total power of agricultural machinery; the canonical variable of agricultural output of China is mainly impacted by grain, oil-bearing crop and fruit; in terms of the selected variables, the output increase of grain, oil-bearing crop and fruit in China arises from the input increase of agricultural chemical fertilizer and machinery, and there is high-degree correlation between the two. According to the conclusions, the policy suggestions are put forward as follows: gradually decrease consumption of chemical fertilizer; increase the use of modern agricultural machinery; increase agricultural irrigation input.

  6. Accessorizing the human mitochondrial transcription machinery.

    Science.gov (United States)

    Bestwick, Megan L; Shadel, Gerald S

    2013-06-01

    The human genome comprises large chromosomes in the nucleus and mitochondrial DNA (mtDNA) housed in the dynamic mitochondrial network. Human cells contain up to thousands of copies of the double-stranded, circular mtDNA molecule that encodes essential subunits of the oxidative phosphorylation complexes and the rRNAs and tRNAs needed to translate these in the organelle matrix. Transcription of human mtDNA is directed by a single-subunit RNA polymerase, POLRMT, which requires two primary transcription factors, TFB2M (transcription factor B2, mitochondrial) and TFAM (transcription factor A, mitochondrial), to achieve basal regulation of the system. Here, we review recent advances in understanding the structure and function of the primary human transcription machinery and the other factors that facilitate steps in transcription beyond initiation and provide more intricate control over the system.

  7. On the mechanochemical machinery underlying chromatin remodeling

    Science.gov (United States)

    Yusufaly, Tahir I.

    This dissertation discuss two recent efforts, via a unique combination of structural bioinformatics and density functional theory, to unravel some of the details concerning how molecular machinery within the eukaryotic cell nucleus controls chromatin architecture. The first, a study of the 5-methylation of cytosine in 5'-CG-3' : 5'-CG-3' base-pair steps, reveals that the methyl groups roughen the local elastic energy landscape of the DNA. This enhances the probability of the canonical B-DNA structure transitioning into the undertwisted A-like and overtwisted C-like forms seen in nucleosomes, or looped segments of DNA bound to histones. The second part focuses on the formation of salt bridges between arginine residues in histones and phosphate groups on the DNA backbone. The arginine residues are ob- served to apply a tunable mechanical load to the backbone, enabling precision-controlled activation of DNA deformations.

  8. The SNARE machinery in mast cell secretion

    Directory of Open Access Journals (Sweden)

    Axel eLorentz

    2012-06-01

    Full Text Available Mast cells are known as inflammatory cells which exert their functions in allergic and anaphylactic reactions by secretion of numerous inflammatory mediators. During an allergic response, the high-affinity IgE receptor, FcεRI, becomes cross-linked by receptor-bound IgE and antigen resulting in immediate release of pre-synthesized mediators – stored in granules – as well as in de novo synthesis of various mediators like cytokines and chemokines. Soluble N-ethylmaleimide-Sensitive Factor (NSF Attachment Protein (SNAP Receptors (SNARE proteins were found to play a central role in regulating membrane fusion events during exocytosis. In addition, several accessory regulators like Munc13, Munc18, Rab GTPases, SCAMPs, complexins or synaptotagmins were found to be involved in membrane fusion. In this review we summarize our current knowledge about the SNARE machinery and its mechanism of action in mast cell secretion.

    2005-01-01

    Numerical methods successively became important in the design and optimization of fluid machinery. However,as noise emission is considered, one can hardly find standardized prediction methods combining flow and acoustical optimization. Several numerical field methods for sound calculations have been developed. Due to the complexity of the considered flow, approaches must be chosen to avoid exhaustive computing. In this contribution the noise of a simple propeller is investigated. The configurations of the calculations comply with an existing experimental setup chosen for evaluation. The used in-house CFD solver SPARC contains an acoustic module based on Ffowcs Williams-Hawkings Acoustic Analogy. From the flow results of the time dependent Large Eddy Simulation the time dependent acoustic sources are extracted and given to the acoustic module where relevant sound pressure levels are calculated. The difficulties, which arise while proceeding from open to closed rotors and from gas to liquid are discussed.

  10. Temporary migration in Shanghai and Beijing.

    Goldstein, A; Guo, S

    1992-01-01

    The Shanghai Floating Population Study was carried out in 1984 with the objective of estimating the number of temporary residents in the city. This was supplemented by the Shanghai Temporary Migration Survey, which obtained information from a sample of 8716 temporary migrants living in households with permanent residents. The Beijing Temporary Migration Survey of 1985 also obtained information from temporary migrants yielding a sample of 3418. The sex ratio of 68 males per 100 females among Beijing's household temporary migrants was considerably lower than the ratio of 92 for those in Shanghai. The median age was 29.6 years for males and 27.7 years for females in the Beijing sample compared to 20.0 and 22.6 years, respectively, in the Shanghai sample. In the Beijing sample 1/3 came from urban places and 2/3 were of rural origin. In contrast, in Shanghai 2/3 came from other urban locations. 1/3 of migrants in Beijing originated in Hebei, the province immediately adjoining the city. Most other temporary migrants came from the regions closest to Beijing. Migrants who stayed in Beijing's hotels cited business as their motivation: over half the men and almost 1/3 of the women. Multiple logistic analysis using pooled data from both cities suggest that under 10% of migrants migrated for work, but far larger percentages came to visit or to stay. 25-44 year olds, males, and nonrelatives cited mainly the economic motive. Children 5-14 years old, immediate relatives, and those from nonadjacent provinces came to the cities to live, while older people (65-69 years old), not immediate relatives, urban persons, and those from adjacent provinces were more likely to come for visits. Among people 25-29 years old over half were expected to come to Beijing to work, while this was true for only 18% of migrants in Shanghai. Temporary migrants living in Beijing had been there for 34 months, while those in Shanghai had an estimated duration of residence of only 26 months.

    2009-05-01

    An integrated ecological evaluation of the Beijing economy was presented in the paper based on the emergy accounting with the data in 2004. Through calculating environmental and economic inputs within and outside the Beijing economy, this paper discusses the Beijing's resource structure, economic situation and trade status based on a series of emergy indicators. Through the comparison of the systematic indicators of Beijing with those of the selected Chinese cities, the general status of the Beijing economy in China is identified. The results also show that most indicators of Beijing are located at middle levels among the selected Chinese cities. Particularly, the environmental impacts, expressed by the ratio of waste to the renewable emergy, and the ratio of waste to the total emergy use, are 84.2 and 0.26, respectively in Beijing in 2004, which indicate that the Beijing economy is greatly reliant on the imported intensive fuels, goods and services with high empower density and environmental loading.

    Straub, Sebastian P; Stiller, Sebastian B; Wiedemann, Nils; Pfanner, Nikolaus

    2016-11-01

    Mitochondria contain elaborate machineries for the import of precursor proteins from the cytosol. The translocase of the outer mitochondrial membrane (TOM) performs the initial import of precursor proteins and transfers the precursors to downstream translocases, including the presequence translocase and the carrier translocase of the inner membrane, the mitochondrial import and assembly machinery of the intermembrane space, and the sorting and assembly machinery of the outer membrane. Although the protein translocases can function as separate entities in vitro, recent studies revealed a close and dynamic cooperation of the protein import machineries to facilitate efficient transfer of precursor proteins in vivo. In addition, protein translocases were found to transiently interact with distinct machineries that function in the respiratory chain or in the maintenance of mitochondrial membrane architecture. Mitochondrial protein import is embedded in a regulatory network that ensures protein biogenesis, membrane dynamics, bioenergetic activity and quality control.

    2016-01-01

    Recently, with the availability of various traffic datasets, human mobility has been studied in different contexts. Researchers attempt to understand the collective behaviors of human movement with respect to the spatio-temporal distribution in traffic dynamics, from which a gravitational scaling law characterizing the relation between the traffic flow, population and distance has been found. However, most studies focus on the integrated properties of gravitational scaling, neglecting its dynamical evolution during different hours of a day. Investigating the hourly traffic flow data of Beijing subway network, based on the hop-count distance of passengers, we find that the scaling exponent of the gravitational law is smaller in Beijing subway system compared to that reported in Seoul subway system. This means that traffic demand in Beijing is much stronger and less sensitive to the travel distance. Furthermore, we analyzed the temporal evolution of the scaling exponents in weekdays and weekends. Our findings m...

    Full Text Available Suburban farmland ecosystems are known to be affected by intensive land use/cover change (LUCC during the process of urbanization in Beijing. We investigated inter-annual changes in carbon sequestration, source, footprint, and eco-efficiency from 2004 to 2012 in the agro-ecosystem of suburban Beijing. Our findings indicated that: (1 Carbon sink increased 2.8 percent annually and the average annual carbon storage amount was 1 058 200 t, with food crops constituting the highest proportion at 80.4% of carbon storage in farmland ecosystems, of which maize contributed 68.5% as the largest constituent; (2 Carbon emission in the system showed a gradually decreasing trend, with agricultural chemicals as significant contributors. The annual average carbon emission was 276 000 tons in the Beijing farmland ecosystem, and decreased approximately 1.3 percent per year. The largest amount of carbon emissions came from agricultural chemicals at 85.4%, of which nitrogen fertilizer was the biggest contributor at 83.7%; ( 3 The carbon footprint also showed a decreasing trend along with an ecological surplus of carbon. The average carbon footprint was 5.71 hm2 in the Beijing farmland ecosystem with decreasing rate at 5.5% annually; however, the carbon surplus showed a downward trend due to reduction in the amount of arable land; (4 Finally, the increasing carbon sink capacity led to higher carbon eco-efficiency, with an annual average of 3.854 kg C·kg-1 CE, carbon sequestration was greater than the amount of carbon released. In summary, the agro-ecosystem in suburban Beijing has sustained a relatively high carbon eco-efficiency, and agricultural production continues to have high sustainability potential.

  17. Ribosome evolution: Emergence of peptide synthesis machinery

    Indian Academy of Sciences (India)

    Koji Tamura

    2011-12-01

    Proteins, the main players in current biological systems, are produced on ribosomes by sequential amide bond (peptide bond) formations between amino-acid-bearing tRNAs. The ribosome is an exquisite super-complex of RNA-proteins, containing more than 50 proteins and at least 3 kinds of RNAs. The combination of a variety of side chains of amino acids (typically 20 kinds with some exceptions) confers proteins with extraordinary structure and functions. The origin of peptide bond formation and the ribosome is crucial to the understanding of life itself. In this article, a possible evolutionary pathway to peptide bond formation machinery (proto-ribosome) will be discussed, with a special focus on the RNA minihelix (primordial form of modern tRNA) as a starting molecule. Combining the present data with recent experimental data, we can infer that the peptidyl transferase center (PTC) evolved from a primitive system in the RNA world comprising tRNA-like molecules formed by duplication of minihelix-like small RNA.

    Full Text Available There have been suggested the courses of the machine technologies refinement in the process of spiked cereals production. The course of their technical update was studied in our previous article. There were analyzed the drawbacks of the modern machine production of crops and we presented the course of their elimination due to the technology optimization, resource and energy preservation, machine technologies of soil improvement and new innovative technological solutions. The suggested technology optimization was designed taking into account rigorous alternation of crops in the rotation, optimizing of breeds and crossbreeds, application of intermediate crops simultaneously with harvesting the previous crop, introducing progressive methods of chemical treatment and synchronous tillage. The resource and energy preservation is based on the combination of technological operations coinciding with the tasks in agricultural terms during a single machinery pass across the field, application of the mobile power unit (UPU-450, low- and ultralow capacity spraying, optimization of choice of certain agrimethods in the process of crop production and the resource calculation of estimated crop yield. In the set of soil improvement courses we have studied the mechanization of the restoration processes of natural soil formation, defecate introduction, the use of stubbly remains, compulsory presence of permanent grasses in crop rotation. New innovative solutions in the crop production technologies include the refinement of the mechanization facilities in tillage, spraying, new methods of crop harvesting (unwinnowed bread, root tow, cleaning of thrashed heap after the harvesting, etc. We have analyzed the ways of mechanization of “organic farming” and seed treatment with biologic mixtures

    The ESCRT machinery drives a diverse collection of membrane remodeling events, including multivesicular body biogenesis, release of enveloped retroviruses and both reformation of the nuclear envelope and cytokinetic abscission during mitotic exit. These events share the requirement for a topologically equivalent membrane remodeling for their completion and the cells deployment of the ESCRT machinery in these different contexts highlights its functionality as a transposable membrane-fission machinery. Here, we will examine recent data describing ESCRT-III dependent membrane remodeling and explore new roles for the ESCRT-III complex at the nuclear envelope.

    2013-04-01

    Fungal aerosols constitute the most abundant fraction of biological aerosols in the atmosphere, influencing human health, the biosphere, atmospheric chemistry and climate. However, the total abundance of fungal spores in the atmosphere is still poorly understood and quantified. PM10 and PM2.5 samples were collected by high volume samplers simultaneously at a rural site (MY) and an urban site (THU) in Beijing, China. Various carbohydrates were quantified by high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD), including the sugar alcohols mannitol and arabitol, proposed as molecular tracers for fungal aerosol. The annual average concentrations of arabitol in PM2.5 and PM10 at the THU site were 7.4±9.4 ng/m3 and 10.3±9.5 ng/m3, and the respective mannitol concentrations were 21.0±20.4 ng/m3 and 31.9±26.9 ng/m3. Compared to PM10, the monthly average concentrations of arabitol and mannitol in PM2.5 did not vary significantly and were present at nearly consistent levels in the different seasons. Moreover, during summer and autumn higher arabitol and mannitol levels than during spring and winter were observed in coarse particles, probably due to different dominant sources of fungal spores in different seasons. In the dry period (i.e., winter and spring) in Beijing, probably only the suspension from exposed surfaces, (e.g., soil resuspension, transported dust, etc.) can be regarded as the main sources for fungal aerosols. On the other hand, in summer and autumn, fungal spores in the atmosphere can be derived from more complex sources, including plants, vegetation decomposition and agricultural activity, such as ploughing; these fungal spore sources may contribute more to coarse PM. Mannitol and arabitol correlated well with each other, both in PM10 (R2 = 0.71) and PM2.5 (R2 = 0.81). Although fungal spore levels at rural sites were consistently higher than those at urban sites in other studies, the findings in our study were

    Full Text Available The "Blue Sky Project" was proposed in 1998 to investigate by how much emissions should be reduced to increase blue sky frequency in Beijing, which hosted the Summer Olympics in 2008. This paper focuses on the temporal variation of visibility and its dependence on meteorological conditions and suspended particles at Beijing using the hourly observed visibility data in Beijing Capital International Airport (BCIA from 1999 to 2007. It has been found that about 47.8% (24.2% of the hours in Beijing are "bad" ("good" hours with visibility below 10 km (equal or higher than 20 km between 1999 and 2007. Due to the high Relative Humidity (RH, summer is the season with the lowest mean visibility in a year. Although PM10 index was reported in a decreasing trend, the increase of RH has resulted in a decreasing trend of visibility over BCIA in the summer from 1999 to 2007. To ensure blue sky ("good" visibility for Olympics 2008, daily mean PM10 index should be reduced to 44 from 86.5. This requires that not only vehicle emissions, but also other emissions should be limited. Observations during Olympics 2008 verify that blue-sky-hour rate has been increased significantly after mean PM10 index was reduced to 56, however, the visibility during the same period of 2009 has returned to the mean standard before 2008.

    Full Text Available For on-orbit calibration of the Beijing-1 multispectral imagers (Beijing-1/MS, a field calibration campaign was performed at the Dunhuang calibration site during September and October of 2008. Based on the in situ data and images from Beijing-1 and Terra/Moderate Resolution Imaging Spectroradiometer (MODIS, three vicarious calibration methods (i.e., reflectance-based, irradiance-based, and cross-calibration were used to calculate the top-of-atmosphere (TOA radiance of Beijing-1. An analysis was then performed to determine or identify systematic and accidental errors, and the overall uncertainty was assessed for each individual method. The findings show that the reflectance-based method has an uncertainty of more than 10% if the aerosol optical depth (AOD exceeds 0.2. The cross-calibration method is able to reach an error level within 7% if the images are selected carefully. The final calibration coefficients were derived from the irradiance-based data for 6 September 2008, with an uncertainty estimated to be less than 5%.

    Kardos, Gregory R; Robertson, Gavin P

    2015-09-01

    Control of the protein synthetic machinery is deregulated in many cancers, including melanoma, to increase the protein production. Tumor suppressors and oncogenes play key roles in protein synthesis from the transcription of rRNA and ribosome biogenesis to mRNA translation initiation and protein synthesis. Major signaling pathways are altered in melanoma to modulate the protein synthetic machinery, thereby promoting tumor development. However, despite the importance of this process in melanoma development, involvement of the protein synthetic machinery in this cancer type is an underdeveloped area of study. Here, we review the coupling of melanoma development to deregulation of the protein synthetic machinery. We examine existing knowledge regarding RNA polymerase I inhibition and mRNA translation focusing on their inhibition for therapeutic applications in melanoma. Furthermore, the contribution of amino acid biosynthesis and involvement of ribosomal proteins are also reviewed as future therapeutic strategies to target deregulated protein production in melanoma.

    Zhang, Yan; Yang, Zhifeng; Fath, Brian D

    2010-09-15

    Using ecological network analysis, we analyzed the network structure and ecological relationships in an urban water metabolic system. We developed an ecological network model for the system, and used Beijing as an example of analysis based on the model. We used network throughflow analysis to determine the flows among components, and measured both indirect and direct flows. Using a network utility matrix, we determined the relationships and degrees of mutualism among six compartments--1) local environment, 2) rainwater collection, 3) industry, 4) agriculture, 5) domestic sector, and 6) wastewater recycling--which represent producer, consumer, and reducer trophic levels. The capacity of producers to provide water for Beijing decreased from 2003 to 2007, and consumer demand for water decreased due to decreasing industrial and agricultural demand; the recycling capacity of reducers also improved, decreasing the discharge pressure on the environment. The ecological relationships associated with the local environment or the wastewater recycling sector changed little from 2003 to 2007. From 2003 to 2005, the main changes in the ecological relationships among components of Beijing's water metabolic system mostly occurred between the local environment, the industrial and agricultural sectors, and the domestic sector, but by 2006 and 2007, the major change was between the local environment, the agricultural sector, and the industrial sector. The other ecological relationships did not change during the study period. Although Beijing's mutualism indices remained generally stable, the ecological relationships among compartments changed greatly. Our analysis revealed ways to further optimize this system and the relationships among compartments, thereby optimizing future urban water resources development.

  18. Agriculture: access to technology limited.

    Science.gov (United States)

    1997-01-01

    From country to country and even regionally, the roles of women in agriculture vary, but most of their labor is in unpaid subsistence production and their contributions tend to be underestimated, according to the results of the [UN] Secretary-General's report. Depending on circumstances, they have complementary roles with men, sharing or dividing tasks in the production of crops, care of animals, and forestry management. In sub-Saharan Africa, for example, women contribute 60-80% of labor in food production for both household consumption and sale, while in Malaysia the women account for only 35% of the agricultural labor force, and in Ireland the participation rate is only 10.4%. Although women make this important amount of labor contributions to agricultural production, "development policies tend to favor export crops to earn foreign exchange and the agricultural research tends to address the improvement of production and technologies for commercial production". This results in limited access for women to technical knowledge and innovations, including irrigation, machinery, farming techniques and extension services. This is strengthened by the fact that most of the extension services target farmers who own land and can obtain credit to invest in input and technology. full text

  20. Analysis of spatial variations and sources of heavy metals in farmland soils of Beijing suburbs.

    Directory of Open Access Journals (Sweden)

    Jianmei Zou

    Full Text Available To understand the effect of intense human activities in suburbs on environmental quality, we obtained 758 measurements of the heavy metals in certain farmland soils of the Beijing suburbs. Multivariate statistical analysis and geostatistical analysis were used to conduct a basic analysis of the heavy metal concentrations, the distribution characteristics and the sources of pollution of the farmland soils in these suburbs. The results showed the presence of eight heavy metals in the agricultural soils at levels exceeding the background values for As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn. In particular, all the measured Cr concentrations exceeded the background value, while As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn were present at 1.13, 1.68, 1.95, 1.43, 1.63, 0.79, 0.92 and 1.36 times their background values, respectively. The results of correlation, factor and spatial structure analyses showed that Cd, Cu, Pb and Zn were strongly homologous, whereas Cr and Hg showed a degree of heterogeneity. The analysis further indicated that in addition to natural factors, Cd, Cu, Pb and Zn in the soil were mainly associated with distribution from road traffic and land use status. Different agricultural production measures in the various areas were also important factors that affected the spatial distribution of the soil Cr concentration. The major sources of Hg pollution were landfills for industrial waste and urban domestic garbage, while the spatial distribution of As was more likely to be a result of composite pollution. The regional distribution of the heavy metals indicated that except for Cr and Hg, the high heavy metal levels occurred in districts and counties with higher organic matter concentrations, such as the northwestern and southeastern suburbs of Beijing. There was no significant Ni pollution in the agricultural soils of the Beijing suburbs.

  8. Aerosol Index Dynamics over Athens and Beijing

    Christodoulakis, J.; Varotsos, C.; Tzanis, C.; Xue, Y.

    2014-11-01

    We present the analysis of monthly mean Aerosol Index (AI) values, over Athens, Greece, and Beijing, China, for the period 1979- 2012. The aim of the analysis is the identification of time scaling in the AI time series, by using a data analysis technique that would not be affected by the non-stationarity of the data. The appropriate technique satisfying this criterion is the Detrended Fluctuation Analysis (DFA). For the deseasonalization of time series classic Wiener method was applied filtering out the seasonal - 3 months, semiannual - 6 months and annual - 12 months periods. The data analysis for both Athens and Beijing revealed that the exponents α for both time periods are greater than 0.5 indicating that persistence of the correlations in the fluctuations of the deseasonalized AI values exists for time scales between about 4 months and 3.5 years (for the period 1979-1993) or 4 years (for the period 1996-2012).

The increasing range was 1%, dropping 5.45% compared with the previous year, as shown in Figure 1. Since 2005, the annual growth rate of the total energy consumption showed a decreasing trend each year. The city's GDP over the same period reached RMB 1.048803 trillion, increasing 9%. The energy consumption rate fell clearly. In 2008, the energy consumption rate was 0.61 tons of standard coal per 10 thousand yuan GDP, a decline of 7.4%.

  12. The challenge of improving visibility in Beijing

    Full Text Available The "Blue Sky Project" was proposed in 1998 to investigate by how much emissions should be reduced to increase blue sky frequency in Beijing, which hosted the Summer Olympics in 2008. This paper focuses on the temporal variation of visibility and its dependence on meteorological conditions and suspended particles at Beijing using the hourly observed visibility data at Beijing Capital International Airport (BCIA from 1999 to 2007. It has been found that about 47.8% (24.2% of the hours in Beijing are "bad" ("good" hours with visibility below 10 km (equal or higher than 20 km between 1999 and 2007. Due to the high Relative Humidity (RH, summer is the season with the lowest mean visibility in a year. Although PM10 index was reported in a decreasing trend (Chan and Yao, 2008, the increase of RH has resulted in a decreasing trend of visibility over BCIA in the summer from 1999 to 2007. To ensure blue sky ("good" visibility for Olympics 2008, daily mean PM10 index should have been reduced from 81 to 44. This requires that not only vehicle emissions, but also other emissions should be limited. Observations verify that blue-sky-hour rate increased significantly after mean PM10 index was reduced to 53 during Olympics 2008, however, the visibility of 2009 returned to the mean level from 1999 to 2007 during the period 8−24 August. RH (aerosol contribute 24% (76% of the improvement of visibility during August 2008.
