Climate-Based Suitability Assessment for Methane Mitigation by Water Saving Technology in Paddy Fields of the Central Plain of Thailand

The alternate wetting and drying (AWD) water management technique has been identified as one of the most promising options for mitigating methane (CH$_{4}$) emissions from rice cultivation. By its nature, however, this option is limited only to paddy fields where farmers have sustained access to irrigation water. In addition, large amounts of rainfall often make it difficult to drain water from paddy fields. Therefore, it is necessary to understand the specific conditions and suitability of an area in which AWD is foreseen to be applied before its CH$_{4}$ mitigation potential can be assessed in view of planning regional and national mitigation actions. In this study, we applied a methodology developed for assessing the climatic suitability of AWD to paddy fields in the central plain of Thailand in order to determine the potential spatial and temporal boundaries given by climatic and soil parameters that could impact on the applicability of AWD. Related to this, we also assessed the CH$_{4}$ mitigation potential in the target provinces. Results showed that the entire area of the six target provinces was climatically suitable for AWD in both the major (wet) and second (dry) rice seasons. A sensitivity analysis accounting for uncertainties in soil percolation and suitability classification indicated that these settings did not affect the results of the suitability assessment, although they changed to some extent the distribution of moderate and high climatic suitability areas in the major rice season. Following the methodologies of the Intergovernmental Panel on Climate Change Guidelines, we estimated that the AWD scenario could reduce annual CH$_{4}$ emissions by 32% compared with the emissions in the baseline (continuously flooded) scenario. The potential of AWD for annual CH$_{4}$ emission reduction was estimated to be 57,600 t CH$_{4}$ year$^{-1}$, equivalent to 1.61 Mt CO$_{2}$-eq year$^{-1}$, in the target provinces. However, we recognize the possibility that other parameters not included in our current approach may significantly influence the suitability of AWD and thus propose areas for further improvement derived from these limitations. All in all, our results will be instrumental in guiding practitioners at all levels involved in water management for rice cultivation.

Water Saving Technologies: A Measure to Avert Fluoride Contamination in Tamil Nadu

Over abstraction of groundwater and over use of phosphatic fertilizer in the farmer's field, one of the cause of fluoride contamination in groundwater. In India, many studies have reported that the groundwater contaminated with fluoride. Tamil Nadu is one among fluoride contaminated state. Farmers are irrigating the crops through groundwater for high water consumption crops such as paddy, maize and sugarcane. Water saving technologies shifted the production function up and also reduced the abstraction of groundwater. An attempt was made to study the level of adoption of agricultural technologies among fluoride affected farmers for major crops and analysed the factors influencing water saving technologies in fluoride affected locales. Primary data was collected from 184 farmers through multistage random sampling technique. Technology adoption index and logit model was used. The results showed that most of the farmers were non adopters of water saving technologies compared to adopters of technologies in fluoride affected locales. Age, education, experience of farmers, farm income, depth of well, awareness about fluoride contamination and contact with extension personnel were significantly influenced the water saving technologies adoption. Therefore, the efforts are required to intensify the extension education activity to increase awareness among the farmers so as to accelerate the process of adoption as it is one of the measure to avert fluoride contamination.

Correction of Postoperative Anemia in Patients undergoing Mitral Valve Replacement through Blood Saving Technology

The aim. To investigate anemia of chronic disease (ACD) in patients with mitral valvular disease, to provide preoperative correction in these patients and to determine the level of postoperative anemia after mitral valve replacement (MVR) through blood saving technology (BST) under artificial circulation (AC).Materials and methods. This is a study of 104 patients operated due to acquired mitral heart defects under AC. According to the baseline Hb, Ht, serum iron (SI) as well as the use of BST during MVR, all the patients were divided into 3 groups. Group A included 47 patients with normal Hb concentration, Ht and SI, who underwent the surgical intervention without BST with blood transfusion. Group B included 35 patients without ACD who were operated without blood transfusion with the use of BST. The group C included 22 patients with preoperative ACD with low Hb, Ht, and SI. A week before surgery the patients of group C underwent preoperative correction of SI and erythropoiesis stimulation using erythropoietin. The patients of group C were operated using BST. Preoperative correction of anemia and the use of blood and BST during surgery in groups A, B, C were compared. The effect of preoperative ACD correction and erythropoiesis stimulation on the level of postoperative anemia in patients operated due to mitral heart disease through BST in group C and with or without correction in group B was studied.Results. The presented research results show that in group A, in order to sufficiently stabilize the level of Hb and Ht during the operation, donated blood components (590.0 ± 83.0 ml of packed red blood cells and 563.0 ± 68.0 ml of fresh frozen plasma) were used. The use of BST in the group B reduced the level of Hb by 17.4%, Ht by 15.8%, thrombocyties by 20.5%, and the intervention could be performed without donated blood transfusion. Preoperative correction of SI and administration of erythropoietin in patients with ACD resulted in 8.6-fold increase in SI, 5.5-fold increase in ferritin and increase in Hb by 8.1% before the intervention. The use of BST and hematopoietic technology during MVR in patients of group C stabilized SI, Hb and platelets in the operative period, which facilitates operations under AC without transfusion of donated blood components.Conclusions.1. In patients of group A, donor blood components (590.0 ± 83.0 ml of packed red blood cells and 563.0 ± 68.0 ml of fresh frozen plasma) were used to stabilize Hb and Ht during MVR without the use of BST.2. ACD correction in patients of group C with mitral heart disease has led to a 8.6-fold increase in SI (p˂0.05), increase in transferrin saturation coefficient by 36.8% (p˂0.05), and 5.5-fold increase in ferritin activity (p˂0.05).3. The use of BST in patients of group B undergoing MVR reduces the level of Hb by 17.4% (* p˂0.05) and platelets by 20.5% (* p˂0.05).4. Preoperative correction of SI with iron (III) hydroxide and hemapoiesis stimulation by erythropoietin in patients of group C with MVR using BST reduces anemia by 10.7% and thrombocytopenia by 5%.

Development of Energy Saving Technologies for Smart Buildings by Using Computer Algebra

Intelligent energy saving and energy efficient technologies are a modern large-scale global trend in the development of energy systems. Accurate estimates of energy savings are important for promoting energy-efficient construction projects and demonstrating their economic potential. The growing digital measurement infrastructure used in commercial buildings increases the availability of high-frequency data that can be employed for anomaly detection, diagnostics of equipment, heating systems, and ventilation, as well as optimization of air conditioning. This implies the application of modern machine learning methods capable of generating more accurate energy consumption forecasts for buildings to improve their energy efficiency. In this paper, based on the gradient boosting model, a method for modeling and forecasting energy consumption of buildings is proposed and computer algorithms for its software implementation in the SymPy computer algebra system are developed. To assess the efficiency of the proposed algorithms, a dataset that characterizes energy consumption of 300 commercial buildings is used. Results of computer simulations show that these algorithms improve the accuracy of energy consumption forecasts in more than 80% of cases as compared to other machine learning algorithms.

Infrastructure, Urban Sprawl, and Naturally-Occurring Asbestos: An Ontological Thought Model for Wicked and Saving Technologies

Abstract Recently, geologists in Southern Nevada discovered new deposits of naturally occurring asbestos and microscopic fibers in rocks and soil. The danger is that inhaling them can lead to mesothelioma. One problem is that this rare cancer often takes decades to manifest. This discovery abruptly stalled a highway project near Las Vegas. Due to this condition, management developed numerous protocols to keep workers safe. Using this case as a “thought model,” the author challenges an established way of categorizing kinds of technologies as they relate to the concept of being. In turn, this thought model reveals that climate change alters the conditions for being, as recognized in the literature. Advancing this conversation requires that we must reclassify some technologies and develop a categorization for those that reflect a different way of thinking as it concerns being.

Optimal Arrangements for Distribution in Developing Markets: Theory and Evidence

A large literature examines demand-side barriers to product adoption. In this paper, we examine supply-side barriers in a setting with limited contract enforcement. We model the relationship between a distributor and its credit-constrained vendors. We show that the optimal self-enforcing arrangement can be implemented by providing vendors with a line of credit and the option to buy additional units at a fixed price. Moreover, the structure of this arrangement is optimal both for profit-maximizing firms and for non-profit organizations with limited resources. We test the arrangement using a field experiment in rural Uganda. We find that the model-implied optimal arrangement increased distribution significantly compared to a standard contract. However, growth was lower than predicted by the model because vendors (i) were unwilling to extend credit to customers, and (ii) did not have access to a reliable savings technology. We discuss several recent technological innovations that help to overcome both of these challenges.

Impact of a low thermal conductive lightweight concrete in building: Energy and fuel performance evaluation for different climate region

Evaluation of energy performance of a proposed lightweight concrete, a structural component, in a building application is a novel approach and significant attempt for the future of energy-efficient buildings. Buildings are one of the largest energy consumers in the world. Thermal protection in a building is the most effective way for energy saving. Many stimulatory measures for the spreading of energy savings technologies have been recently applied into the building sectors. In this study, an investigation was carried out based upon an experimental investigation to decide the thermal properties of the lightweight concrete with different ratios of vermiculite. Moreover, analytical simulation to evaluate the energy consumption in a real building application was carried out for various fuels and different climate regions of Turkey. The results show that the most significant reduction in the total heat need occurs in the 4th region, with about 5.6 kWh/m2-year for a thickness of 0.2 m. An energy-saving of 7.5% can be achieved in the 1st region. The proposed concrete can provide a significant reduction in energy consumption and can reduce the carbon emission related to the lower energy need of the buildings. The annual saving can increase to 0.61 $/m2 for LPG in the 4th region. The payback period varies between 1.4 years and 9 years, depending on the fuel. Many OECD countries having a high population pay higher prices for electricity and natural gas compared to Turkey. It means that such an energy-efficient material can save more price due to their higher fuel cost.

Banker my neighbour: Matching and financial intermediation in savings groups

Efforts to promote financial inclusion have largely focused on microcredit and micro-savings separately, less so on promoting financial intermediation across poor borrowers and savers. Village Savings and Loan Associations (VSLAs) may enable borrowers and savers to meet each others' needs, by combining a borrowing and a commitment savings technology. On the other hand, frictions such as imperfect information and enforcement may limit VSLAs’ ability to attract both borrowers and savers into the same group. To investigate whether VSLAs provide effective financial intermediation, we use a large-scale survey of mature VSLA groups in rural Malawi. We find that VSLAs mobilize large quantities of savings that are then lent to individual members at high interest rates, yielding savers a large return on their savings. We examine whether this process is assisted by the sorting of members across VSLAs. We find that present-biased individuals tend to group with time-consistent members, consistent with the hypothesis that the former gain a commitment savings technology by lending to the latter. In contrast, members of the same occupation sort into groups together, indicating unrealised intermediation possibilities between farming and non-farming households. This has implications for the design of such groups.

Discussion on Energy Saving Technology of Pumps and Fans in Thermal Power Plants

Pumps and fans play an important role in various sectors of the national economy, and are widely used in metallurgical, chemical, textile, petroleum, coal, electric power, national defense, light industry and agricultural production sectors. Because pumps and fans are general machinery, they are in nationals. The various sectors of the economy are widely used in production and life. From the production point of view, the proportion of power consumption of pumps and fans is very high, and its annual electricity consumption accounts for about one-third of the national electricity consumption, accounting for 40% to 45% of the national industrial electricity consumption. It can be seen that the power consumption of the pump and the fan itself is quite large, which requires the pump and the fan to work under low energy consumption and high efficiency conditions to achieve energy saving. I analyzed and summarized the actual problems encountered in daily production operations, and provided technical support. These technical experiences provide some reference experience for daily operation and equipment management.
