Energy Consumption

The substitution of this potential applied in the equation for energy consumption renders an equation for energy consumption as a function of the cleanup time and characteristics of the system, but not of the electrical operation conditions In conclusion, several factors affect energy requirements for electrokinetic remediation at a specific site, including the properties of soil and contaminants, electrode configuration, and time of operation. As previously explained, the current or potential is changing along the process because soil resistance is doing it the energy consumption does it as well. However, these kinds of approximate procedures using average values permit an estimative calculation of the energy expenditure per unit volume of treated soil for electrokinetic remediation with one- and two-dimensional configurations of electrodes

Practical Applications

Using NCR, we have quantitatively imaged boron in plants at the tissue and cell levels for agronomical purpose 30, 57, 77, 83, 98, 106 . A part of this work was done in Costa Rica with the support of the International Atomic Energy Agency . In flax seedlings, boron concentrations were measured in the vacuoles and in the primary and secondary walls of cells in various tissues. In the foliar parenchyma of clover seedlings, boron was shown to come from seed reserves and root uptake in

Energy Demand and Carbon Sequestration

While some North American research has studied the reduction of energy demand through shading of houses in summertime and shelter in winter (e.g., McPherson 1994), no comparable studies have been performed in a European context. Energy studies have concentrated mostly on the built environment. The overall direct carbon sequestration by urban trees accounts for less than one percent of carbon emissions from urban areas (McPherson 1994). Still, more important will be the indirect effects of trees in reducing energy demand of buildings. It has been estimated that, for Sacramento County, California, the urban forest of approximately 6 million trees sequesters 238 000 t of CO2 per year. The urban forest further reduces energy consumption indirectly as carbon dioxide emissions from the local power plant are avoided by an estimated 75 600 t CO2 yr this is because the presence of trees leads to reduced demands for household heating and air conditioning (McPherson 1998). Moreover, the use of...

D1 Metabolism is Photoregulated

Directly affects the photochemistry at the reducing side of PS II. This would support theories regarding this protein as a functional component of the secondary acceptor of PS II. On the other hand, maintenance of the low, steady-state level of the 32 kDa protein in the light, in spite of its massive synthesis, represents a programming of gene expression designed for regulation. Expression of such regulatory genes is characterized by high energy costs, which purchase an ability to respond quickly, dramatically, and temporarily to perturbations in the steady state. Such features are characteristic of the 32 kDa protein. Thus, further experimentation will be required to decipher the exact role of this protein in photosynthetic electron transport.

Low Oxygen Effects on Seed Metabolism

As shown above, legume embryos develop in a hypoxic environment. The question arises what is the significance for seed metabolism The principal effects of O2 deficiency are well described. An initial pH shift caused by ATP hydrolysis and onset of fermentation is followed by the inhibition of metabolic activity and the induction of anaerobic response genes, including fermentative and some glycolytic enzymes (Drew, 1997 Geigenberger et al., 2000). The balancing of ATP demand and supply pathways is shifted towards energy-saving metabolic pathways, thereby conserving the energy charge of the cells. Can such changes be found in seed development The low O2 levels found here could represent a signal that induces adaptive energy-saving metabolic responses. The repression of invertase but induction of sucrose synthase by low O2 is considered to be part of this metabolic shift (Zeng et al., 1999). Compared with invertase, sucrose synthase saves one ATP molecule and therefore represents an...

31PNMR studies of phosphate metabolism

Phosphorus-31 has been the most extensively studied nuclide in intact cells by NMR (for reviews see Loughman and Ratcliffe, 1984 Ratcliffe, 1987 Campbell-Burk and Shulman, 1987). These studies have generally sought information about the energetic status and the cytoplasmic pH of the cell or tissue, the former from the levels of intracellular high- and low-energy phosphates (primarily ATP and Pi), and the latter from the chemical shift of Pi and some other endogenous or added titratable phosphorus-containing compounds. In yeasts (Gillies et al., 1981), mycorrhizal fungi (Martin et al., 1983), and algae (Kuesel et al., 1989) 31P-NMR has also been used to study polyphosphate (PolyP) metabolism.

Rehydration of Leaves and Resynthesis of Functional Chloroplasts

Three days after rewetting Xerophyta leaves, the ultrastructure of chloroplasts is back to normal and their photosynthetic apparatus is again fully active in photosynthetic quantum conversion and net CO2 assimilation. This is also the time range in nature when the rainy season begins after a longer dry period. In the nature, desiccation as well as regreening and revival of desiccated leaves can proceed various times for the same leaf. Even with detached desiccated Xerophyta leaves, collected at the natural habitat, we could perform several desiccation and rewetting cycles in the laboratory. This again demonstrates that the desiccoplast is a unique chloroplast that is different in its revival capacity from the gerontoplast stage of the chloroplasts of other plants. The PDT strategy can be thought of as not only being superimposed on an existing cellular protection mechanism of vegetative desiccation tolerance (Oliver et al. 2000), but as a distinct new class of DT strategy. The...

Nodule Metabolism Nitrogenase complex

Since this reaction uses high amounts of ATP it has high-energy costs ( 960 kJ mol of fixed N2). The nitrogenase enzyme can use instead of N2 other substrates like cyanide, azide, NO and acetylene. The latter is used in the acetylene reduction test to quantify the nitrogenase activity.

Nitrogen fixation and assimilation

The high-energy costs of the nitrogen fixation process are paid by the plant by photosynthesis products. It has been estimated that nitrogen fixation in the nodules of clover and other leguminous plants may consume as much as about 20 of the total photosynthate (Haystead et al. 1980). To provide this energy sacharose is transported from the leaves via phloem to the nodules. There it is hydrolysed to monosaccharides and subsequently phosphoenolpyruvate is formed. The high metabolic activity of the nodule is reflected by the abundance of phosphoenolpyruvate carboxylase, which is about 1 to 2 of total soluble nodule protein (Pathirana et al. 1992). It catalyses the formation of oxaloacetate, which is subsequently reduced to malate. This dicarboxylic acid is the major energy source for the bacteroids and plant mitochondria and is used for

Revival of Metabolism Reassembly or Repair

The ATP amount conserved in the desiccated state is highly variable among the HDT and PDT desiccation-tolerant species. Besides this, there is no indication of extreme energy costs of a desiccation-rehydration cycle (Gaff and Ziegler 1989). Therefore, the speed of recovery is not a matter of available energy. It depends rather on the extent a certain species retains its internal structures during desiccation. This, in turn, is determined mostly by the strategy (i.e., HDT or PDT) adopted by the plant in order to avoid harmful excitation of chlorophyll in the drought-stressed state (Sherwin and Farrant 1996, 1998).

Electric Operative Conditions

Other authors 44,72,73 prefer to operate in a laboratory, applying constant DC potential gradients in the range 30 to 400 V m-1. In this operative mode, when the resistance of the soil increases, the electrical current naturally goes down. Obviously, in this case, the conductivity control of soil is determining for cleaning time because the capacity of the electromigration to move ions basically depends on intensity through the soil. If the process operates to constant voltage and is not controlled 72,73 , at the beginning of operation, a sharp increase in the protons and hydroxyl concentrations is produced in the anode and cathode compartments, respectively, and is responsible for the corresponding increment of electric current and cleanup rate. Afterwards, the depletion of free ions due to extraction and neutralization results in a high resistance in a specific zone of the soil and a high useless drop potential. This effect produces a reduction of the most important electrokinetic...

Metal Element Cycling and Translocation by ECMF

ECMF are considered highly efficient recyclers of mineral nutrients, which minimize element losses through leaching. Very high affinities to certain nutrients can result in the uptake of similar non-essential elements, for example Rb and Cs that are accumulated by certain ECMF along with K. High bioconcentration factors (BCFs) for certain non-essential trace elements are a side effect of high affinity essential element capture. The efficiency of ECM element recycling can be illustrated by the observation that radioactive Cs has hardly been leached from forest soils more than 20 years after the fall out impact caused by the accident in the nuclear power plant in Chernobyl (Dighton et al. 2008). The ability of ECM fungi to capture cationic nutrient elements and to limit losses due to leaching is particularly

Urban Climate in Europe

The most important factors are the change of the natural surface characteristics into artificial structures with artificial materials. This results in changes of the biosphere with less green covered surfaces with a pronounced effect on the physical environmental conditions of radiation, wind, temperature and humidity. Urban trees and urban forests play a key role in controlling the local and regional aspects of these changes. On the micro-scale, each tree has a potential to influence the microclimate conditions as well as energy consumption for housing and living (Cofaigh et al. 1996). The green space in the urban environment not only influences the urban climate but also has a pronounced effect of the whole city interacting with the surrounding landscape. Therefore, urban greenery faces changed climate conditions in urban areas but also influences the complete urban environment.

Weight Sizing Color Sorting And Packaging Apples Pears Peaches Nectarines Plums and Apricots

Fruit-packing orientation and materials are very important. Fruit that look good going into the shipping carton may not look good upon arrival at their destination because the wrong packing materials were used. During shipping, fruit are exposed to vibrations and changes in acceleration that can result in significant bruising. Compression bruising can also appear if cartons collapse or fruit are packed too tightly. If fruit are not immobilized in the carton, they can develop scuffing marks from the friction of vibration. All these factors can result in the rejection of the product by retailers and or consumers. It is imperative to select packing materials that protect the fruit, minimize weight loss, are lightweight to reduce shipping and energy costs, and are recyclable and environmentally friendly.

A A Role For Biomass Crops

How much biomass is needed Of the 105 exajoules (EJ, 1018 J) of energy consumed in the US in 2008, only 4 or 4.1 EJ came from biomass sources, mainly from combustion of wood residues for heat and power by paper manufacturers (DOE, 2009). Energy consumption is expected to increase by 14 by 2034, to 120.8 EJ (DOE, 2010). Multiple acts of legislation currently under consideration in the US could further increase renewable energy demand 10-40 , leading it to comprise 14 of the total US energy demand, or 17 EJ y 1, by 2035 (DOE, 2010).

Improving Sequence Coverage of Peptides and Proteins

Another way to avoid missing any co-eluted peptides is the so-called expression scanning 20 . The instrument scans peptide ions in a single MS mode but alternates between low and high collision energy in the collision cell. At low energy, peptides are detected as precursor ions. Conversely, at high energy they are detected as fragment ions that are corresponding to MS MS. Sequences of individual pep-tide precursors can be deduced from the high-energy spectra using an automated program to precisely align the m z and retention time between a precursor and its fragments. In this case, all co-eluted peptides become fragmented in the high-energy mode without selection or discrimination, which differs from DDA-based MS MS that is selective scanning for individual peptide precursors. However, the sequence data generated from the expression scanning is a mix of many peptide precursors, and highly intelligent software is required to perform the analysis. At present, there is still need for...

Active Monitors of Stress in Forest Ecosystems

Two differently polluted forest sites in the emission area of Thermal Power Plant Sostanj were submitted to studies of mycorrhizal inoculum potential in different years, before and after the installation of cleaning blocks in the Thermal Power Plant. Emissions were reduced from 80.516 t SO2 in 1994 to 44.253 t in 2000, and the tests were done in 1992-1993 and in 2002-2003. The percentage of mycorrhizal short roots of potted seedlings from Zavodnje (polluted substrate) was significantly lower (p 0.05) in comparison with that of Pohorje (unpolluted), suggesting that the mycorrhizal potential of the more polluted area was lower (Fig. 13.4). Other growth parameters of the seedlings were also different the fresh weights of roots, stems, and needles were higher in Pohorje (Al Sayegh Petkovsek and Kraigher 2003). Pollution influenced the mycorrhizal potential of forest soils and this negative impact was still present more than 5 years after the reduction of the emissions. We conclude that...

Signals Mediated by Reactive Oxygen Species and Stress Related Processes

Hydrogen peroxide (H2O2) is the principle ROS in plants. It is mainly generated at PSI under conditions when excitation exceeds energy usage by the dark reaction, e.g. under high light or in low temperature. Such conditions lead to over-reduction of the electron transport chain and to electron transfer from ferredoxin to oxygen generating superoxide (Fig. 4). This is detoxified by the superoxide dismutase (SOD) resulting in accumulation of hydrogen peroxide which is reduced to water by antioxidant enzymes such as APX. In this reaction ascorbate is used as electron donor and replenished by reduction via glutathione (Pfannschmidt 2003). Cytosolic APX enzymes are induced by oxidative conditions and therefore represent good markers for cellular stress (Shigeoka et al. 2002). In Arabidopsis high-light induction of nuclear genes apx1 and apx2 could be correlated to the action of H2O2 as a signalling molecule (Karpinski et al. 1997, 1999. Foyer and Noctor 1999) . Interestingly apx2 was also...

Applications of Stoichiometric Modeling

Examples of the application of stoichiometric modeling to photosynthetic systems include the work by Yang et al. 95 who used a stoichiometric model of central metabolism to investigate carbon and energy metabolism of Chlorella pyrenoidosa under autotrophic, mixotrophic, and cyclic light (autotrophic) and dark (heterotrophic) conditions (assuming steady state under both light and dark conditions). The model was divided into two compartments a chloroplast and a combined cytosol and mitochondrion, with a total of 67 reactions and 61 metabolites describing glycolysis gluconeogenesis, Calvin cycle pentose phosphate cycle, the TCA cycle, nitrate assimilation, amino acid synthesis, and reactions related to energy transduction via cofactors such as NAD(P)H and ATP. Measured inputs to the model included glucose and nitrate uptake rates, biomass composition and growth rate, and incident light flux. Care was taken to remove singularities (linearly dependent reactions) from the metabolic network,...

Performance of a potential C4 rice overview from quantum yield to grain yield

Analysis of losses of potential fixed carbon when scaling up from quantum yield to RCF identifies the differences between C3 and C4 plants. The scaling-up progresses from photochemistry in the cell (nanoseconds) through leaf and canopy photosynthesis (seconds to hours) to crop growth (weeks to months). Rice and maize differ in several respects. Rice has losses from photorespiration but maize has a lower theoretical quantum yield because of the energy costs of the C4 pathway. In the hierarchy of scale, there are losses at the cell level from inactive absorption of PAR and these are smaller in maize than in rice. The loss at the transition between leaf and canopy photosynthesis is also smaller in maize. Scaling up from leaf to canopy includes changing from leaf photosynthesis unsaturated for PAR (in which each additional unit of absorbed PAR produces the same additional amount of fixed carbon) to photosynthesis by the canopy with leaves at varying saturation depending on PAR Incident on...

Uptake of Radionuclides by Higher Plant Roots

Following the steady accumulation of radionuclide inventories in soils around the world during the period of atmospheric nuclear weapons testing prior to 1963 interest in the contribution of root uptake processes to crop contamination burgeoned. Of particular concern were the relatively long-lived isotopes 90Sr and 137Cs (half-lives 28 years and 30 years, respectively) which, as chemical analogues of Ca and K, are particularly prone to biological incorporation. The principal interest during this classical period of radioecology was the equilibrium situation where an approximately constant input of radioactivity to the ground surface as a result of fallout from the atmosphere led to a steady rate of transfer into the plant from surface layers of soils. More recently, however, and particularly since the accident at the Chernobyl nuclear power plant in 1986, the effect of 'spike' releases on plant contamination via root uptake has become of great importance, especially when the...

Decision Support Systems

The system seems especially suitable to show, in a cost effective way, that is easy to understand for non-experts, how preserving green areas will lead to reduced expenses for storm-water retention and energy consumption. Furthermore air quality improvement and carbon sequestration can be estimated.

The Dissipative Ecological Unit DEU the interdependence of organisms

Within the DEU, there is regulation through a potentially perfect feedback, wherein the 'bottom-up' and 'top-down' controls collapse into one another, in favour of a basic 'control loop'. Its stability and durability may be assessed from the temporal efficiency of local resource use. This control loop implies that there is a management span, in which management by the food chain is regulating energy efficiency in such a way that the daily energy pulses, for example, are smoothed to give an increased efficiency of energy use. With resource cycling at a maximum, residual energy potentials can be better deployed. Expressed in ecological terms, relating to the processes of production and respiration, this means the maximisation of gross productivity but with a reduction in net productivity towards zero. Energy pulses are more completely dissipated and energy flux is maximally attenuated. In a typical DEU, attenuation of the energy flux proceeds by way of (1) evaporation of water (2)...

Natural convection dryer

It is an up gradation of the Bhatti curing system, developed by TATA Energy Research Institute, New Delhi. The solid fuel i.e. firewood through biomass gasification and thermo chemical reaction is converted into gaseous fuel by partial combustion. A mixture of producer gas consisting of CO (Carbon monoxide), H2 (Hydrogen), CH4 (Methane), CO2 (Carbon dioxide) and N2 (Nitrogen) is obtained, which is combustible and is used to burn. Through updraft type of biomass gasifier, air enters the gasifier from bottom and producer gas is taken out from top for curing cardamom.

The UrReaction Center

The Ur-RC probably had a bidirectional electron transfer chain, using chlorophyll-type pigments, although likely not the exact pigments that we know today. These pigments are clearly the product of a long evolutionary process that has optimized them for light absorption and efficient electron transfer properties. There is every reason to expect that the impressive quantum efficiencies of close to one for modern RCs developed over a long time, and that earlier complexes were significantly less efficient. As Erasmus said, In the land of the blind, the one-eyed man is king, so even an inefficient light-storage system is better than none at all. Evolution subsequently relentlessly improved the quantum efficiency so that there remains little more room for improvement. The same cannot be said for the energy efficiency of photochemistry, which is significantly less -in most cases, it is only a few tenths of percent. While the dramatic difference in the evolutionary optimization of quantum...

International organisations and analyses of global change

The sum of many small individual decisions This ranges from individuals to the world society (see Fig. 5.4.3). Within this range are a number of organisations that have particular interest in global change (WBGU 2001b), those that have direct influence on land use, e.g. FAO (Food and Agriculture Organisation), or indirectly through the decisions it makes, e.g. the WTO (World Trade Organisation). Between these types of organisation are the financial organisations that have no direct contact with agriculture and forestry, but that distribute resources and so have a more direct impact on nations than the WTO. A few examples are the World Bank, IMF (International Monetary Fund) and the GEF (Global Environmental Facility, which finances projects in the area of biodiversity and energy saving), as well as the UNDP (United Nations Development Programme).

Bioaccumulation And Trophic Transfer Of Trace Elements

Exposure resulting from terrestrial and aquatic food chains to humans and biota must be analyzed separately due to the fundamental differences between them. The number of trophic levels in the terrestrial food chain is greatly reduced compared to the aquatic food chain. Moreover, the terrestrial herbivores demonstrate low efficiency of converting plant biomass into protein due to a large percentage of indigestible structural material containing high levels of cellulose and lignin in terrestrial plants. However, the low energy efficiency causes higher consumption rates of food stuffs in herbivores, which can effectively intensify metal uptake in food webs within contaminated areas 17 .

Genetic Basis of Agronomically Significant traits

A collection of attributes sets most rosaceous crops apart from field crops and model species. These attributes include perenniality, large plant size, extended juvenility, use of rootstocks, clonal propagation and highly perishable products (strawberry being an exception to the first four attributes). Product quality, rather than yield, is critical for profitability. From the perspective of Rosaceae crop industries, key needs are to (1) improve fresh and processed product quality, shelf life and safety, including the development of novel or improved flavors, textures, aromas, and colors, for a healthier and more satisfied consumer (2) reduce chemical pesticide use and develop stress tolerant plants for greater environmental sus-tainability and (3) decrease labor and energy costs of crop production (The U.S. Rosaceae Genomics, Genetics, and Breeding Initiative White Paper, 2006). The traits associated with these needs, including (1) fruit, nut, and flower postharvest quality, (2)...

Transgenic soybean boom and policy support

Demonstrated in South American countries (Brazil, Argentina and Bolivia). In Argentina, there is widespread legalization and adoption of transgenic soybean. In Brazil, soybean-producing states have been offered tax breaks to stimulate production, while in Bolivia the state has subsidized energy costs. In Brazil and Argentina, public funds have been used for research that benefits the private sector.

Concluding Remarks

Current advanced greenhouse technology for plant propagation and transplant production has been well developed for a large-scale production. Thus, for the development of a large-scale photoautotrophic micropropagation and transplant production system, technologies of plug seedling production, hydroponic culture, greenhouse environment control, and greenhouse crop management can be applied with careful consideration of disease protection. The current photoautotrophic micropropagation system can be improved further for a larger scale production by incorporating recent technologies of computers, robotics, energy-saving, recycling, environmental conservation, ecological engineering, etc. At the same time, photoautotrophic micropropagation is suitable also for a small-scaled operation.

Conclusions and Implications Policy and Research for the Soybean Sector

The review performed in this chapter has finally generated some unanswered questions for future research. Due to its strategic importance in terms of foreign currency earning and its versatile uses, governments of the soybean-producing countries (especially in South America) invest a great deal in supporting the soybean sector. Are all the policy support interventions (e.g. tax breaks, subsidies on energy costs, commodity price support to domestic producers, export subsidies) economically justified and worth implementing Are they sustainable Should they be replicated in other soybean countries or regions The ever-changing climate is expected to influence soybean production and thereby processing and marketing. Is the change in favour or against soybean production, and how What is the environmental impact of the expansion of soybean production Soaring energy costs have huge implications for the production, processing, marketing, import and export of soybean crops. The need for...

Effect of policy on pattern of soybean trade

The USA has now enacted the Energy Policy Act of 2005, which set a goal of producing 28.5 billion l of biofuel by the year 2012. More ambitious is the Energy Independence and Security Act of 2007, which sets a goal of producing 136 billion l of biofuel (of which 4 billion l will be biodiesel) by 2022 (Tyner, 2008). This has led to a robust growth in biodiesel production from soybean. The Acts are accompanied by subsidies and other incentives for farmers, developers of technologies and biofuel producers (see Tyner, 2008, for a complete review). Efforts to increase biofuel production have been driven by the need to reduce CO2 and sulphur emissions. The USA enacted Clean Air Act amendments in 1990, seeking to lower sulphur emissions (Tyner, 2008). Assuming that only soybean-based biodiesel is blended with fossil diesel to achieve the Clean Air Act, it will require 15 of USA soybean production (Ash et al., 2006).

Constraints to Global Soybean Marketing and Trade

The South American soybean sector model has inherent limitations. The three cases of Brazil, Argentina and Bolivia show the limitations of the South American soybean sector model. While liberalization and an agro-export orientation have benefitted some producers, the strategy is based on undervalued natural resources and foreign enterprises dominate all parts of the industry except the farming - financing, input supply, processing, marketing and export operations. Despite dynamic growth in productivity and output, the soybean sector in South America has seen a significant drop in employment (Perez et al., 2008). This fall in employment, in addition to foreign dominance and the capital-intensive nature of this sector in South America, raises questions as to the role of this crop in the lives of the poor and equity implications. In this context, the governments of soybean-producing South American countries have adopted various policies to support the industrial soybean sector, which...

Advantages and Disadvantages of Dryers

Disadvantages higher specific energy consumption, danger of uneven drying across the height of layer, higher labor demand for filling and discharging of dryer or high investment costs for automation of product handling, staged drying can be carried out only with high expense in time control of relative humidity of waste air. Advantages high throughput per drying area, suitable for a small range of different products, staged temperatures and air velocities easy to adapt to the drying curve of all products, even drying through several product turning by gravity dumping, lower energy consumption, corresponds to the structure of a working day in medium and large farms and agricultural enterprises, low labor demand for filling and discharging. In general the investment costs rise with increased degree of automation, causing lower specific energy costs and lower specific labor costs, too.

Trends Of Melissopalynological Work In India

The small stingless bees (Meliponinae) and honeybees (Apinae) are often described as cross-pollinators because of their opportunistic behaviour, low energy demand and short flight ranges. These bees are known to move 'en masse' with the pollen adhered to them to other conspecific plants in the flower (Bawa 1980). This kind of en masse movement has been also demonstrated in the mass blooming Terminalia tomentosa where nectar respertion occurs simultaneously in all open flowers (Atluri et al., 2000 b).

Plastids In Root Of Taeniophyllum

Velamen Radicans

In exposed habitats, quantasomes will be smaller. In the shade, antenna size (thus quantasome size) increases, the better to harvest scarce photons the Chi a b ratio decreases. Investments in carboxylases, electron carriers, and other components of the energy-transducing apparatus are also cut dark respiration lessens as metabolic rate is generally reduced. A lower specific leaf weight (dry weight per surface area) is an especially effective economy measure in low-energy sites. Other distinctions between sun and shade photosynthesis are based on more complex, poorly understood mechanisms (Chazdon and Pearcy 1986). Shade leaves quickly respond to sunflecks and can store enough acquired energy to continue fixation briefly after shade returns. Sun leaves are better able to dissipate excess energy and avoid photoinhibition of photosystem II.

Percent Survival During Acclimatization Ex Vitro

Of the total costs for ex vitro acclimatization in the PAM, 20 was spent on the construction of the greenhouse, 56 was spent on labor, 19 was spent on supplies such as substrate, electricity, water, fertilizer and pesticide and 5 was spent on other items. On the other hand, in the PMM, 11 was spent on the construction of the greenhouse, 38 was spent on labor, 11 was spent on supplies such as substrate, electricity, water, fertilizer and pesticide and 40 was spent on other items. The lower cost of ex vitro acclimatization in the PAM than in the PMM was mainly due to a higher percentage of survival ex vitro and less labor. The cost for in vitro multiplication, which was equal to that for in vitro rooting, in the PAM was 58 of that in the PMM (Table 6). Labor cost in the PAM was less than half of that in the PMM. This result is consistent with the prediction by Kozai et al. (2000). The reduced labor cost in the PAM significantly reduced the cost for in vitro...

Quantifying Amenity Benefits in Monetary Terms

The methods used in estimating non-priced benefits of forests include the contingent valuation method (CVM), the hedonic pricing method (HPM), and the travel cost method (TCM). Furthermore, approaches such as tree pricing and environmental benefit valuation have been applied in assessing urban forest benefits (Tyrvainen 1999). The methods have different abilities to capture different benefits (Table 4.2). For example, hedonic pricing mainly captures recreational and aesthetic benefits of green areas, whereas environmental benefit valuation focuses on air quality and the energy saving function of trees.

Features of Organic Farming

Conventional farms consumed considerably more energy than organic farms largely because they used more petrochemicals. Also, organic farms were considerably more energy-efficient than conventional farms. Between 1974 and 1978 the energy consumed to produce a dollar's worth of crop on organic farms was only about 40 percent as great as on conventional farms.

Materials And Methods Used

Fly ash was collected from the electrostatic precipitator of a lignite-fired electric power plant in Northern Greece and aged for 3 months by maintaining in open air and leaching periodically with deionized water. The material was strongly alkaline (pH 12.1) its heavy metal composition is shown in Table 4.2. Sewage sludge was the same for both experiments and it was collected from the waste water treatment plant of the city of Tirnavos (central Greece). Its composition determined according to Leschber et al. 24 is shown in Table 4.3.

Inhibition of chlorophyll biosynthesis

Chlorophyll is the principal pigment in photosynthesis. In addition to a light-harvesting function, chlorophyll is located within reaction centres, and so it plays a pivotal role in the movement of electrons from low energy (H-O) to high energy (NADP+). The Observations that diphenyl ether action was particularly sensitive to low energy blue light led to the suggestion that carotenoids could mediate singlet oxygen generation. However, Matringe and Scalla (1988) have shown typical phytotoxic symptoms in carotenoid-free cell lines and instead reported the accumulation of protoporphyrin IX in treated plants. These authors have since conclusively demonstrated that protopor-phyrinogen oxidase is the target enzyme (Matringe et al., 1989).

Dedication

The editors dedicate this volume in the series Advances in Photosynthesis and Respiration to Teruo Ogawa, who has made numerous original contributions to the field of photosynthesis. Teruo began his graduate studies in the laboratory of Professor Kazuo Shibata in the early 1960s, at the Tokyo Institute of Technology. At that time, techniques for the biochemical separation of chlorophyll-protein complexes using detergents began to flourish. Teruo described the first electro-phoretic separation of chlorophyll-protein complexes using sodium dodecyl sulfate. This and the concurrent work of Philip Thornber solidified the concept that chlorophyll is coordinated by protein in the photosynthetic membrane and marked a signal point in the path that has ultimately led to the high resolution crystal structures of the photosystems and light-harvesting complexes. Teruo continued this line of investigation joining the lab of Professor Leo Vernon as a postdoc at the Charles F. Kettering Research...

Part I

Photosynthesis is carried out by virtually all land plants. The only exceptions are some non-green parasitic or saprophytic species. The algae are also photosynthetic and land plants plus algae are sometimes collectively referred to as 'the green plants'. The green plants are photoautotrophic (literally 'light-self-feeding'), needing only light and inorganic compounds CO2, water and mineral ions. There are also photosynthetic bacteria (although some of these are photo-heterotrophic, i.e. they need a supply of organic C compounds). The photoautotrophs are the primary producers and they form the basis of food chains. Plant organic matter is ingested as food by animals, fungi and other microorganisms. Any organic material synthesized by these non-photosynthetic organisms is regarded as secondary production, being derived from the photosynthetic products. As indicated in the lower part of Fig. 2.1, the cycles of biosynthesis and respiration are repeated in the secondary producers....

Natural Ventilation

To improve the air exchange and thus the growth, normality and quality of the plants, the vessel need to be ventilated i) naturally (natural ventilation) or ii) forcedly (forced ventilation). Natural ventilation is the energy-efficient process of bringing outer fresh air inside the culture vessel and extracting the same amount of air from the vessel. Natural ventilation generally takes place through the air gap between the vessel and the lid or through a gas permeable microporous film (pore diameter 0.2 - 0.5 m Figure 1a) attached on the lid (Figure 1b) or on the wall of the vessel. Driving force for gas exchange in a tissue culture vessel under natural ventilation are i) the pressure gradient between the inner and the outer environment ii) the temperature gradient between the inner and the outer environment and iii) the velocity and current pattern of the air surrounding the vessels. Therefore, the shape of the vessel, orientation of the lids and vents, air current and environment...

Batch Method

The plant material is brought and evenly distributed in a supporting basket of the still. After tightly screwing on the cover, steam is introduced. The distillation is carried out at atmospheric pressure. To prevent water distillation, condensed water is drained off through an outlet provided for this purpose. The specific lighter chamomile oil is separated in a Florentine bottle. Because of the water-soluble nature of the chamomile oil, a series of several Florentine bottles is necessary. An almost complete separation of the oil is achieved through a coalescence filter at the end of the series 3 . The alternating feeding and emptying of the vessel results in process interruptions, which necessitate high operational and energy costs.

Energy Resource

On the other hand, use of solar energy for heating water for washing, autoclaving and other purposes is practical for reducing energy costs in micropropagation. Temperature of well or city water ranges between 15 and 30 C in most places and this can be raised to 50-70 C using a solar energy collector with a black-colored double layer panel through which the water flows. If water of 100 C is required then instead of heating the water of 25 C directly using fuel, if it is preheated to 70 C using the solar energy collector and then heated to 100 C using fuel, the fuel consumption is reduced by 67 100 (70-25) (100-25) .

Oil extraction

Soya Lecithin Plant

Technology has improved plant capacity and reduced solvent and energy losses. The technology of supercritical (SC) fluid extraction (SCFE) is emerging as a safe and viable extraction system. Extrusion-aided mechanical extraction of soybean oil is an environment-friendly technology for the production of soybean oil and edible-grade soy cake. Membrane technology may be used for separation of oil from miscella. Physical refining offers an increased oil yield and reduced energy consumption. Refined soybean oil is used in various types of cooking and may also be converted into margarines, shortenings and other products. Soy lecithin has many usages. Soy by-products such as soy meal, with 50 protein, offer a wide range of products for food and livestock feed. Soy hull is a good source for the production of single-cell protein for animal feed. throughout the world. Solvent extraction technology is normally preferred for low-oil seeds such as soybean. Better mechanical and thermal designs...

Carrion flower

Ecology Unlike most species of Smilax, carrion flower is an herbaceous, rather than woody, vine with smooth, rather than prickly, stems. Both male and female flowers are strongly odiferous, producing a carrion-like odor (hence the common name) that attracts flies, bees, and beetles. Bees and carrion flies are the primary pollinators. Beetles are less effective because they rarely move among flowers or plants, and their smooth bodies carry less pollen. The flowers lack nectar, so pollen (present only in male flowers) is the sole reward. The large stigma lobes of female flowers mimic the pollen-laden anthers of male flowers thus, female flowers use a form of deception to attract potential pollinators. This deception is reinforced by the nearly identical appearance and odor of the male and female inflorescences. Most populations have more males than females because the higher energy costs of producing fruit results in higher mortality rates for female plants.
