Effects Conservation Tillage On Ground Water Quality: Nitrates and Pesticides
by Terry J LoganNowadays the environmental sustainability of the cropping systems is increasingly requested by the consumers. Conventional tillage practices, totally turning over the soil between the vineyard rows, may cause erosion due to rain as well as structure destruction of the soil in the long term. Conservation tillage is a soil management technique, poorly widespread in Sardinia, allowing cover cropping between vineyard rows. Furthermore, this technique makes the canopy development control of herbage possible by cutting it up during specific phenological phases. Conservation tillage usually involves direct benefits to farmers such as increasing soil fertility as well as reductionof tillage costs, soil erosion and carbon dioxide (CO2) emissions in the atmosphere. This long term trial, during at least five years aims to assess the conservation tillage impact on chemical-physical soil characteristics in comparison with traditional tillage by evaluating the change of organic matter, C.E.C. and availability of major plant nutrients in the soil and to estimate their probable rise. The field plots are located in a 35% slope condition vineyard, showing massive erosion problem and organic matter low content. A split/plot design with four replications was set up, with the comparison between conservation and traditional tillage apart as main plots. Moreover, the effects of two different irrigation levels were evaluated in the subplots of each main plot. At the beginning of the trial (2011) a pedological survey was made. Three soil profiles were described and sampled along the field slope and soil sampling in each plot were made both to characterize the soil and to find the zero point. The soil chemical and physical characteristics were monitored through a second soil sampling made at the end of 2013. Conservation tillage caused increasing organic matter content and C.E.C. values. As for major plant nutrients in soil, results were more uncertain. Grapevine yield and quality parameters did not show any negative effect when passing from conventional to conservation tillage techniques. The trial provided a preliminary positive evaluation of conservation tillage. However, more years are required to confirm this trend.

Effects of Electromagnetic Radiation on Living Beings
by Felix A. FarretThe objective of this book is to show in detail how electromagnetic waves existing in the environment can affect the electrochemical currents present in the brains and bodies of living beings that serve to communicate with their internal organs as well as with other living beings. These electromagnetic waves are distributed intensively by current means of communication (television, cell phones, radar, medical equipment, electrical machines, electrical networks, etc.) and by the stars in the Universe. Such waves can affect in one way or another the electrochemical currents of living beings, which seem to be currently interpreted as sensations, hypnosis, telepathy, intuition, spells, mediumship, visions and precognition, as well as other less widespread forms, such as telekinesis, radiesthesia, clairvoyance, precognition and teleportation. Several world-famous examples of these possibilities are illustrated in the final chapter of this book.Key Features: 14 examples of diverse international case studies included Challenges conventional ways of thinking by exploring the intersection of electromagnetic waves and extrasensory perception Equips readers with insights into the various effects of electromagnetic waves in daily life, which promotes awareness of their environment and its different influences and how they impact people Provides an engineering framework for understanding extrasensory beliefs and aims to explain the concept of historical brain believing in a better manner
Effects of Herbicide-Tolerant Crop Cultivation
by Michel Beckert Yves DessauxOverall, this work identifies key points to be taken into account when drawing up guidelines that govern the use of herbicide-tolerant (HT) crops in order to preserve the effectiveness of this innovation over time. This multidisciplinary expert report, based on an international literature review, assesses the effects of the cultivation of crops possessing HT traits. HT crops may appear to be useful complementary tools when farmers are facing certain difficult weed-management situations or in the context of a diversification of weed-control strategies. Their repeated use, however, can rapidly induce changes in the weed flora that can constitute more complex challenges in terms of weed control. Issues coming up with the development of agricultural production systems including HT crops are the objects of this expert report: what are the perceptions of these varieties by society and the reasons for their adoption by farmers? Are the savings on herbicides promoted by seed companies long-lasting? Can the cultivation of HT crops impact biodiversity?

Effects of Wetland Conversion to Farming on Water Quality and Sediment and Nutrient Retention in a Tropical Catchment (IHE Delft PhD Thesis Series)
by Abias UwimanaThe study used a combination of landscape-scale synoptic surveys (catchment, reaches) and mesocosm surveys (experimental plots) to assess the impacts of conversion of natural valley-bottom wetlands to farming land on the water quality and retention of sediment and nutrients. The results showed that temperature, pH, electrical conductivity and dissolved oxygen concentration decreased, and total suspended solids (TSS) increased with storm water increase. Nitrogen (TN) and phosphorus (TP) accumulated in the catchment during the dry season and washed into the water courses during the early stages of the higher flows, with subsequent lower concentrations at the end of the rains due to dilution. Large proportions of the annual loads of TSS, TP and TN (93%, 60% and 67%, respectively) were transported during rainfall events that occurred in 115 days. Fishponds acted as temporal traps of TSS, TN and TP at the early stages of farming, and were a source of and TN and TP at the end of the farming period, in contrast to rice farming that generated sediments and nutrients early in the farming period and trapped them at the end of the farming season. Wetlands mostly acted as sinks but sometimes as a source of sediment and nutrients.
Effects of the Deletion of Chemical Agent Washout on Operations at the Blue Grass Chemical Agent Destruction Pilot Plant
by Engineering Medicine National Academies of SciencesThe United States manufactured significant quantities of chemical weapons during the Cold War and the years prior. Because the chemical weapons are aging, storage constitutes an ongoing risk to the facility workforces and to the communities nearby. In addition, the Chemical Weapons Convention treaty stipulates that the chemical weapons be destroyed. The United States has destroyed approximately 90 percent of the chemical weapons stockpile located at seven sites. As part of the effort to destroy its remaining stockpile, the Department of Defense is building the Blue Grass Chemical Agent Destruction Pilot Plant (BGCAPP) on the Blue Grass Army Depot (BGAD), near Richmond, Kentucky. The stockpile stored at BGAD consists of rockets and projectiles containing the nerve agents GB and VX and the blister agent mustard. Continued storage poses a risk to the BGAD workforce and the surrounding community because these munitions are several decades old and are developing leaks. Due to public opposition to the use of incineration to destroy the BGAD stockpile, Congress mandated that non- incineration technologies be identified for use at BGCAPP. As a result, the original BGCAPP design called for munitions to be drained of agent and then for the munition bodies to be washed out using high-pressure hot water. However as part of a larger package of modifications called Engineering Change Proposal 87 (ECP-87), the munition washout step was eliminated. Effects of the Deletion of Chemical Agent Washout on Operations at the Blue Grass Chemical Agent Destruction Pilot Plant examines the impacts of this design change on operations at BGCAPP and makes recommendations to guide future decision making.

Efficiency Evaluation of Energy Systems
by Ibrahim Dincer Mehmet Kanoğlu Yunus A. ÇengelEfficiency is one of the most frequently used terms in thermodynamics, and it indicates how well an energy conversion or process is accomplished. Efficiency is also one of the most frequently misused terms in thermodynamics and is often a source of misunderstanding. This is because efficiency is often used without being properly defined first. This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies. The book will be particularly useful for a clear understanding of second law (exergy) efficiencies for various systems. It may serve as a reference book to the researchers in energy field. The definitions and concepts developed in the book will be explained through illustrative examples.

Efficient Algorithms for Discrete Wavelet Transform
by K K Shukla Arvind K. TiwariDue to its inherent time-scale locality characteristics, the discrete wavelet transform (DWT) has received considerable attention in signal/image processing. Wavelet transforms have excellent energy compaction characteristics and can provide perfect reconstruction. The shifting (translation) and scaling (dilation) are unique to wavelets. Orthogonality of wavelets with respect to dilations leads to multigrid representation. As the computation of DWT involves filtering, an efficient filtering process is essential in DWT hardware implementation. In the multistage DWT, coefficients are calculated recursively, and in addition to the wavelet decomposition stage, extra space is required to store the intermediate coefficients. Hence, the overall performance depends significantly on the precision of the intermediate DWT coefficients. This work presents new implementation techniques of DWT, that are efficient in terms of computation, storage, and with better signal-to-noise ratio in the reconstructed signal.
