The city of Aripuana is one of the largest wood producer in the state of Mato Grosso, Brazil. Wood residues are used in the electricity generation at three thermoelectric plants in this region. However, the plants have high costs in transporting the wood residues (due to poor road conditions). Hence, this paper compares the energy performance of wood residues in natura and compacted as briquettes by calculating the heating value and determining the influence of moisture content on the energy characteristics of wood residues. The goal is to demonstrate the viability of using briquettes in order to improve thermoelectric generation. The wood residues from this region are affected by the high humidity of the biome. An alternative to improve the use of energy contained in the wood residues is to produce briquettes with lower humidity. This allows one to maintain high levels of heat energy in a lower volume, facilitating handling and storage. The results show that the use of briquettes improved the performance of thermoelectric plants, generating 1 MW of electricity power with less than 1 ton of briquettes. This contributes to the preservation of the environment, reducing operating costs, transportation and storage of the raw materials.

Building energy-use models and tools can simulate and represent the distribution of energy consumption of buildings located in an urban area. The aim of these models is to simulate the energy performance of buildings at multiple temporal and spatial scales, taking into account both the building shape and the surrounding urban context. This paper investigates existing models by simulating the hourly space heating consumption of residential buildings in an urban environment. Existing bottom-up urban-energy models were applied to the city of Fribourg in order to evaluate the accuracy and flexibility of energy simulations. Two common energy-use models—a machine learning model and a GIS-based engineering model—were compared and evaluated against anonymized monitoring data. The study shows that the simulations were quite precise with an annual mean absolute percentage error of 12.8 and 19.3% for the machine learning and the GIS-based engineering model, respectively, on residential buildings built in different periods of construction. Moreover, a sensitivity analysis using the Morris method was carried out on the GIS-based engineering model in order to assess the impact of input variables on space heating consumption and to identify possible optimization opportunities of the existing model.

AbstractA pre-economic feasibility study was undertaken to determine the potential of cereal straw for industrial utilization in Minnesota. Specifically, utilizing straw for pulp and paper manufacture was of interest. The availability of cereal straw fiber supplies at various locations across the state of Minnesota, along with pre-processing issues such as transportation, harvesting, handling, and storage, are discussed and priced. The greatest economic advantage of straw for industrial use appears to be the low cost of the raw material compared to traditional raw materials. This also provides an excellent opportunity for additional income for farmers. The methodology and information provided here should be helpful in evaluating the feasibility of utilizing straw for other industrial purposes in other parts of the world. However, in some Third World countries, long-standing on-farm, traditional uses of cereal straws for fuel, fiber, and animal feed may limit their availability for industrial utilization.

The considerable diffusion of ready-to-eat products has focused attention on the reasons for their increasingly prominent success in the market. Although their prices are much higher than the prices of simple raw materials, their consumption has increased rapidly and with no end in sight, a situation that has challenged the conclusions of the classical literature on the importance of price and/or income in consumer decisions. In fact, more recent literature has broadened the classical vision by introducing potential additional variables that could influence consumer choice of certain foods. These variables, however, are not always easy and clear to identify because they reflect the cultural characteristics of a society. For this reason, the French scholar Malassis has introduced the concept of a model of food consumption, which, in fact, stems from a concept of food consumption as driven by factors that are not the same for all the societies that might be studied. Among these variables, regarding the consumption of ready-to-eat products, a factor that certainly acts as a driving force in an increasingly frenetic and dynamic society is the time saving that they are able to provide. Thus, it was considered essential to analyze this in a concrete way, through the variance analysis of a sample of 77 subjects resident in the city of Palermo, noting their characteristics in terms of age, education level, and number of nuclear family members. The results obtained indicate that subjects who consumed ready-to-eat products at a higher frequency belonged to a higher age group, had a higher level of education, and belonged to a family that was not particularly numerous. With these results, it can be stated that the consumption of ready-to-eat products is influenced by people’s need to optimize their available time, considered as a real, scarce resource.

This paper looks at the City of Melbourne's new office development CH2 as a case study of world class energy performance. In particular, the integrated design of conventionally independent systems has led to the potential to deliver significant savings to the Council and to deliver better environmental conditions to building occupants that in turn may contribute to satisfaction, well-being and productivity. It is concluded that this project has the potential to be an iconic example of effective implementation of ESD (environmental sustainable design) principles and therefore act as a demonstration project to others. Energy efficiency of more than 50% of current benchmarks for Melbourne is effected. Energy harvesting is defined as arising from squander, waste and nature, which is a new concept introduced in this paper to better describe the design decision process.

The high rate of divorce, especially in West Sumatra, is an important note for religious extension workers to increase their role and quality in providing counseling. Therefore, fast and progressive action is needed to overcome this. Another phenomenon revealed from the above data is that the divorce case is dominated by the wife's lawsuit. Therefore, it takes the role of religious counselors at the Office of Religious Affairs (KUA) to increase family resilience. The purpose of this study was to determine the role of religious instructors in increasing family resilience in the city of Padang from physical, social, and psychological aspects. Data collection techniques used interviews and were analyzed with the Miles and Huberman models following the stages of data reduction, data display, conclusion. The role of religious counselors in increasing family resilience has been carried out quite well, although not yet maximized because the raw materials are not yet available, the methods used are only advice and lectures and have not been evaluated continuously.

Standardization in Ayurvedic formulations ensures the establishment of standards for the quality and purity of raw materials, quality control during the drug manufacturing process, production of a good quality finished product, storage and distribution to maintain the quality of the final product. It is an essential tool for establishing quality control methods for Ayurvedic drugs. In Ayurveda, standardization has been well defined and documented in the classical and contemporary texts. Still, these have been written with an individualistic intent and not for industrial or commercial purposes.  Careful contemplation of the classical literature of Ayurveda was done, the current guidelines of WHO on standardization of herbal drugs, latest researches on the same via the internet were explored and examined in the purview of the newest standardization procedures.  In this article, an attempt has been made to bring to light the classical references related to standardization, the milestones in this on-going pursuit have been exhibited, with the use of the latest scientific methods being incorporated for a standardized Ayurvedic drug. It can be concluded from the review that standardization in Ayurveda is an on-going process where one needs to be strictly vigilant about the new scientific methods to study the fine chemical procedures and the intermediate compounds formed, but at the same time be aware of the classical. Ayurvedic methods concepts of the procedure. Asava-arista's medicinal characteristics of Ayurvedic classical dosage forms, liquid dosage forms based on self-generated alcohol with faster absorption, long shelf life, and increased market conformity have led to a continuous rise in demand. New fermentation methods and packaging innovations tend to have been embraced by many Ayurvedic processing units. The importance of standardization of such goods is underlined by these advances in manufacturing, distribution and storage. Therefore, it is of concern to examine the latest manufacturing situation and the standardization of the dosage type regarding the procedure and the consistency and effectiveness of the finished product. In addition to the effort to include criteria of consistency and standardization, the study consists of an overview and deliberates on the importance of improvements made to the conventional preparation processes, ingredients and material used in the process and the potential impact on its efficacy.

Abstract This study discusses the interplays between urban form and energy performance using a case study in Singapore. We investigate educational urban quarters in the tropical climate of Singapore using simulation-based parametric geometric modelling. Three input variables of urban form were examined: street network orientation, street canyon width, and building depth. In total, 280 scenarios were generated using a quasi-Monte Carlo Saltelli sampler and Grasshopper. For each scenario, the City Energy Analyst, an open-source urban building energy simulation program, calculated solar energy penetration. To assess the variables’ importance, we applied Sobol’ sensitivity analysis. Results suggest that the street width and building depth were the most influential parameters.
