Title: Winter weeds add organic matter to soil in orchards
Time : 13:45-14:15
Biography:
Judith M Tisdall has experience in basic and applied research in soils. She was awarded JK Taylor Medal for excellence in research and communication (2012). Her 52 papers have been cited 3487 times in the scientific literature (HI=18). She was the first to recognize the mycorrhizal effect on soil aggregation. She led a project on soil management for crops in Indonesia that enabled farmers to double their incomes. She contributed to new soil management for fruit trees on Tatura Trellis. She is an Editor-in-Chief of Soil & Tillage Research and is a Member of Editorial Board of Agronomy.
Abstract:
Fruit trees need soft stable soil (with plenty of organic matter) in the tree-line to enable feeder roots to grow and take up water and nutrients in summer. Why does a plant bother to produce roots? The plant uses energy, carbon, nutrients and water to produce the roots. Why? The plant needs roots for uptake and storage of nutrients and water, anchorage and production of hormones and phytoelexins (defense against pathogens). Organic matter (OM) helps to supply most of these needs and ranges from living plants and animals (>0.25 mm diameter), to highly decomposed humic materials (<2 µm diameter). OM provides: (1) Nutrients to plants, (2) Nutrients, carbon and energy to the many organisms in soil, (3) Buffers soil against rapid changes in chemistry, (4) Acts as slow-release fertilizer and (5) Improves soil structure. The rhizosphere (near the root surface) supports a large population of organisms; all part of OM. Winter weeds are an easy way of adding OM to soil in the tree-line. Living roots of weeds continually exude simple organic materials, then die and are replaced by new roots. The grower should allow weeds to grow in the traffic-line in winter but kill them with herbicide in summer, so they will not compete with the tree roots for nutrients, water and space. The grower should slash dead weeds in the traffic-line and throw them onto the tree-line as mulch. Soil animals gradually mix the organic mulch with the soil and avoid tillage. The mulch also decreases evaporation from the surface and protects the soil from heavy rain and lethal high temperatures in summer. This enables feeder tree roots to grow in soft stable soil and the trees to produce high yields.

Abstract:
Scientists in different fields study behavior of rivers, which is significantly influenced by human activities, climatic change and many other factors that change mass and energy balance of the rivers. Influenced by the aforementioned factors, the river flow may range from being simple to complex, fluctuating in both time and space. Therefore, it is of interest to determine the nature of complexity in river flow processes, in particular in different parts of its course that cannot be done by traditional mathematical statistics which requires the use of different measures of complexity. It seems that one of the key problems in hydrology is that instead of use of complexity measures in analysis of river flow, hydrologists rather use traditional statistical methods, which are not usually adequate since they are mostly based on assumptions which cannot find a niche in complex systems analysis. We have used the Kolmogorov complexities and the Kolmogorov complexity spectrum to quantify the randomness degree in river flow time series of seven rivers with different regimes in Bosnia and Herzegovina, representing their different type of courses, for the period 1965-1986. We have calculated the Kolmogorov Complexity (KC) based on the Lempel-Ziv Algorithm (LZA) (lower-KCL and upper-KCU), Kolmogorov complexity spectrum highest value (KCM) and overall Kolmogorov complexity (KCO) values for each time series. The results indicate that the KCL, KCU, KCM and KCO values in seven rivers show some similarities regardless of the amplitude differences in their monthly flow rates. The KCL, KCU and KCM complexities as information measures do not see a difference between time series which have different amplitude variations but similar random components. However, it seems that the KCO information measures better takes into account both the amplitude and the place of the components in a time series.

Abstract:
The near-surface temperatures of the Earth are strongly affected by the precession angle (Ψ). Precession, in a revolving body, occurs due to the deviation of its mass distribution from the complete arrival symmetry. Precession angle affects the Earth’s climate. Decrease of the precession angle is accompanied by a noticeable cooling of the climate. Glaciation emerges as soon as the Earth’s average temperature reaches some critical value. As a result of the interaction between the Moon and Earth during the Pleistocene time, slow (but orderly) climate cooling episodes occurred periodically. The cooling periods lasted about 100,000-120,000 years and magnitude of cooling was 8-10 oC. After the formation of thick ice covers, the climate warmed up by the same amount after a few thousand years. Glaciation degraded just as rapidly. Thus, Sorokhtin et al. (2010) were able to forecast the climate changes in the future. In the future (2020), despite releases of atmospheric gases, there will be a severe cooling down period.

Abstract:
There is a perception among the inhabitants of the Aburra Valley Region, that the zone has been suffering big temperature raises in the last years, especially in the last decade. To give perspective about this issue, the authors have gone through the available information about temperature changes on three meteorological stations and have correlated it with a set of variables of urban, climatic and energetic nature with the intention of developing an approximate model to understand the temperature changes. Raises in the mean temperature, based on the linear tendencies were estimated on 0.47 °C for the 20 years between 1995 and 2015; 60% of the raise is due to the local activity and 40% due the impact of global warming. Nevertheless it is a complex behavior, which has oscillations. In order to visualize and model the changes, it was necessary to linearize the behavior and understand the relation between the measuring stations, its geographical position and their altitude above the sea level. On the most representative station of the urban impact, the linearized temperature behavior was correlated with the mentioned variables. The differences between the temperatures and their linearized changes were acceptably correlated with global and local climatic influences. Significant results allowed understanding the city impact and its energetic performance on the temperature.

Abstract:
Most researchers agree that Pleistocene is characterized by glacial and inter glacial periods which are strongly related to dry/cool and wet/warm climates. Apparently these are reflected on their pollen records. The period of dry climate (glacial climate) is characterized by abundant Gramineae pollen, whilst the period of wetter climate (interglacial climate) is indicated by an increase of coastal and mangrove palynomorphs but greatly reduced frequencies of Gramineae pollen. On the contrary, previous works on the Pleistocene sediments of Java indicated high abundance of grass pollen along this age marking drier climate condition. This paper publishes the study which is intended to evaluate paleoclimate of Java and other area of Indonesia during Pleistocene. For this purpose, some well samples from East Java and Papua were collected. Standard laboratory preparation was employed to extract pollen from the cutting samples. This study applies quantitative method which allows detail climate change interpretation. This study shows that Pleistocene of East Java is characterized by abundant grass pollen of Monoporites annulatus which may correspond to the period of expansion of savanna vegetation coinciding with glacial period. Moreover, it is indicated by abundant charred Gramineae cuticles which are derived from burning grass. This might have been caused by extreme heat which could relate to the volcanic activities existed in East Java. Slightly different record appears in Papua which shows repetition of dry/wet condition or low/high sea level. The moist climate related to the phase of sea level rise is marked by abundant brackish pollen which possibly represented interglacial period. It is also supported by the increase of peat swamp and freshwater palynomorphs. On the other hand, dry climate representing glacial period is defined by significant decrease of these brackish and freshwater elements.

Abstract:
Thermal treatment is one of the effective methods to rapidly treat the oil-contaminated soil. However this method costs much due to the high energy consumption comparing with other conventional treatments. Microwave is recently regarded as an energy source to enhance the energy efficiency for the thermal treatment of the oil-contaminated soil. In this study, the feasibility of microwave thermal desorption technology was investigated to treat the polluted lubricating oil-contaminated soil. Microwave thermal desorption technology has been recently developed in Korea as a technically-effective as well as cost-effective technology for the remediation of lubricating oil-polluted soil. This technology uses microwave and microwave absorber as an energy source to enhance the energy efficiency for the thermal treatment of the lubricating oil-contaminated soil. Based on a series of field test results from this study, it was found that microwave thermal desorption technology can substantially reduce the remediation cost of oil-contaminated soil with low electric power consumption and contribute to low CO2 emission.

Abstract:
India is one among the many water-starved nations of the world and it increasingly faces declining surface and groundwater resources while the usage continues to escalate aggressively in recent decades. Although the annual monsoons bring enough rain, most of the rainwater cannot be harvested and stored due to inadequate water storage facilities. The world water use has tripled since the 1950s, so politicians have met this increasing water demand by building more big dams that alarmed environmentalist due to various negative side effects that range from loss of farmlands to repatriation of millions of displaced people. So, the question is, can big dams resolve all the looming water shortages and climate change consequences? What about building more eco-friendly small dams across all rivers? Can they mitigate climate change? A small non-profit agency in India has assisted over 1,000 villages in the semi-arid regions of Gujarat, Rajasthan and Madhya Pradesh States to build cost-effective check dams in rivers to harvest rain water for three decades. Water saved through the check dams not only transformed the infertile dry lands into productive agricultural lands but also increased ground water recharge ultimately benefiting the environment. This model has remarkable potential to be replicated in developing countries to reduce irrigation water stress and river water conflicts.

Title: Aqua-space suit as new geotechnology and universal human preventive mean during of heliophysical and climatic changes
Biography:
Alexander Trofimov has received Diploma of the Doctor from Novosibirsk State Medical University in 1973 and Doctor of Medical Sciences in 1998. He has served as ISA Professor in 1999, Academician of International Academy Energy-informative Sciences in 2001, Academician of ABI, USA in 2010, General Director and Chief of Scientific Council of International Scientific Research Institute of Cosmoplanetary Anthropoecology (ISRICA) and Chief of Laboratory Helioclimatopathology of Science Center of Clinical and Experimental Medicine of Siberian Department of Russian Academy of Medical Science. He has also received DSc from Open International University for Complementary Medicine in India in 1998. He wrote more than 300 scientific works, 7 monographs and received 9 patents. His basic research interests are in heliobiology, cosmic anthropoecology, geoecology, geophysics, helioclimatopathology, preventive medicine and investigation of water as a helioprotective mean.
Abstract:
We believe that at sequence of climatic and heliophysical events of last time, the main role have our magnetosphere. Accordingly the buffering properties of the geomagnetic field, which protects biosystems from excess solar proton-electron beams, are decreasing. Our main aim was the development at these conditions of preventive non-medicinal geotechnologies. It is shown, that our new technological means, so as informational holograms and drinking water, patented by ISRICA in Russia, has helioprotective properties and contributes to significant positive inversion of the functional dependence of activity of many human functional systems on heliogeophysical impacts. The non-medicinal means on the basis of drinking water treated light-hologram’s impact in the weakened geomagnetic field, which reduces the excess heliomagnetotropic reactions of a man and promotes prevention of crisis states (on an example of patients with hypertension) was developed and successfully tested. Treatment of drinking water by informational holograms in the weakened geomagnetic field, in our opinion, leads to such changes in its nanoclusteral structure, energy-information capacity and bio-catalytic activity that provide heliomagnetoprotective effect in relation to a man on the systemic and organism levels.

Title: Coal fires a major source of greenhouse gases: A forgotten problem
Time : 13:00-13:30
Biography:
Hartwig Gielisch is an Exploration Geologist, studied at the Ruhr-University Bochum, Germany. Since more than 20 years he works as Geologist and Exploration Manager in natural resource exploration projects, mainly searching for hard coal and lignite. He is a qualified/competent person for natural resource estimation reports and registered as European Geologist (Certificate No. 752) with the European Federation of Geologists EFG, Brussels, Belgium. Since 2006, he works in India, exploring several coal fires and has extinguished fires together with Coal India Ltd.
Abstract:
Coal fires seriously pollute the environment in several states of the world. Today most coal fires are manmade and emerge from illegal or unprofessional mining activities. The most disastrous coal fires of the world currently occur in China and India. In China the program "Big Step Forward" in the beginning of the 60’s together with inefficient small scale mining is the main reason of the 750 coal fires in China, where almost 200 m of excellent, near surface coal were burned in uncontrolled coal fires. In India disregard of standards with regards to coal fire prevention is the reason of the burning coal fields. The Jharia Coalfield in Jharkhand started burning in 1916 and burns this year for 100 years. General data on the volume of coal, which burns in Indian coal mine, are not available. In general, coal fires start as result of unprofessional or illegal mining activities in open pits and uncontrolled, inactive coal mines by self-combustion of coal. Self-combustion is mainly controlled by the grain size of the coals, in other words the smaller the grain size the higher the risk of oxidation and subsequent temperature build-up. Many coal fires burn underground with variable supply of oxygen. Hence, the coal does not burn completely like in power plants, but it smolders in the underground. Emissions from these smoldering fires and an incomplete combustion of the coal create dust and greenhouse gases such as NOX, CO2, CO2, CO and CH4. These emissions pollute the soil, groundwater and the atmosphere. Coal fire experts discuss since years the percentage and the cumulative influence of coal fires on global warming and climate change. Until now the percentage of greenhouse gases resulting from coal fires is unknown. The quantification of this percentage is a future duty of firefighting companies and organizations.

Abstract:
Extreme weather events such as floods, storm surges, hurricanes, snowstorms, thunderstorms, tornados, droughts, heat/cold waves and others are among the most pronounced impacts of climate change. It is a commonly accepted knowledge that frequency of extreme weather events is increasing due to climate change which causes an increasing monetary damage to economic systems. In this study, extreme weather events are classified and their major attributes are discussed. Accordingly various statistical techniques to derive relationships between those events and their attributes are reviewed. As well, various methodologies to estimate economic impact from extreme weather events are analyzed in terms of their strengths and weaknesses. Main goal of this study is to design a model that connects economic monetary loss from extreme weather events due to climate change to its attributes in order to be able to predict future losses and to find the threshold for investments in mitigation and adaptation measures.

His area of expertise includes CO2 capture and sequestration, biotechnology, water treatment and purification, membrane separation and plasma technology. Most of his recent research work focuses on the development of new, environmental-friendly technologies for the oil and gas industry.
Abstract:
Carbon dioxide is known to be a major contributor to global warming and climate change and hence has an adverse effect on environmental sustainability. CO2 is emitted by various activities associated with industrial processes and the burning of various types of carbonaceous fuels such as coal, oil and gas. Over the past few years, there has been a considerable amount of interest in carbon capture and storage (CCS) as an option to mitigate the harmful effects of CO2 emissions. This study evaluates a new approach to the capture and sequestration of CO2 through reactions with high salinity water in the presence of an alkaline agent. Processes such as the Solvay process have been successful in utilizing the reactions of CO2 with ammoniated high salinity water to sodium bicarbonate. This process, however, suffers from several drawbacks such as inefficient contact mechanism and the need for the regeneration of ammonia as alkaline catalyst in the process. Such drawbacks have been addressed through developing a new, inert particles reactor system that offers efficient mixing and stable operation. At the same time, carbon dioxide is reacted with high salinity water in the presence calcium hydroxide instead of ammonia to provide the alkalinity needed for the reaction of CO2 and NaCl. The new process and reactor system were able to achieve high CO2 capture efficiency (up to 99%) and effective reduction in water salinity (up to 40%), while storing the CO2 in a stable solid form, namely sodium bicarbonate. The new process can utilize any alkaline solid waste and the inert particles reactor system can be used to capture CO2 from different sources such as natural gas or flue gas.
