Zero Energy Buildings

In the current century, a suitable strategy is concerned for optimal consumption of energy, due to limited natural resources and fossil fuels for moving towards sustainable development and environmental protection. Given the rising cost of energy, environmental pollution and the end of fossil fuels, zero-energy buildings became a popular option in today's world. The purpose of this study is to investigate the factors affecting the design of zero-energy buildings, in order to reduce energy consumption and increase productivity, including plan form, climatic characteristics, materials, coverage etc. The present study collects the features of zero-energy building in Isfahan, which is based on the Emberger Climate View in the arid climate, by examining the books and related writings, field observations and using a descriptive method, in the form of qualitative studies. The results of the research showed that some actions are needed to save energy and, in general, less consumption of renewable energy by considering the climate and the use of natural conditions.

During the last few decades there has been a sharp transition in economic doctrine, within the context of economic growth, on the relative contributions of agriculture and industrial development. There has been a shift away from the earlier 'industrial fundamentalism' to an emphasis on the significance of growth in agricultural productivity and production. The focus, especially in the context of the present-day less developed countries like Pakistan, has sharpened with the rapid growth in demand for food, resulting from the increasing growth in population and the high income-elasticities of the demand for food. Coupled with this is the transition from resource-based agriculture to science-based agriculture. Agricultural economists are unanimous in the view that by the end of this century all increases in world food production will come from higher yields, i.e. increased output per hectare. This increasing emphasis on 'land-saving' technology to increase productivity and production has resuited from the growing population pressures on land and declining land-man ratios. Agricultural research has come to the fore in providing technologies that increase productivity and production. However, these technologies do not explicitly take into account the equity aspects of the problem. The extent to which the poor gain or lose from the introduction of a new agricultural technology depends on a host of complex and interrelated socio-economic and political factors such as the existing distribution of productive resources, access to modem inputs, the structure of the market, etc.

Chemical Disinfection

This study aimed to identification of an ecological alternative for the chemical disinfection of soil in the greenhouses from Romania. Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops in the world. The carbohydrate, vitamins, salts of important mineral elements and organic acids content of tomato fruits is very important. Tomato crops are very sensitive to climatic vagaries, so fluctuation in climatic parameters at any phase of growth can affect the yield and the fruit quality. Grafting on Solanaceae is a method which has improved and spread quickly during the past years, a similar approach to crop rotation, a practice meant to increase productivity, resistance or tolerance to biotic and abiotic stress factors and at increasing fruit quality. The research was conducted in a glass greenhouse of the Horting Institute, Bucharest, Romania. The biological material used was a Romanian tomato hybrid (Siriana F1), a Dutch tomato hybrid (Abellus F1) and four rootstocks, a Dutch tomato hybrid (Emperador F1) and three Romanian tomato cultivars (L542, L543 and L544) obtained from the Research and Development Station for Vegetable Growing, Buzău, Romania. The rootstocks have had resistance to biotic stress factors (soil diseases and pests) and the chemical disinfection of soil has was eliminated. The result of this research are presented in this paper.

Rice being a staple food crop of Kashmir valley, the focus is on enhancement of yield in order to meet the needs of ever-growing population.Identification of new parental lines is crucial for developing ecology-specific hybrids with ideal agronomic performance. Exploitation of heterosis in the form of hybrid rice technology can be one of the approaches to increase productivity in this crop, especially exploiting diversity among japonica lines can serve as an excellent route.A number of CMS lines suitable formountainous areas of Kashmir have been developed, however, the availability of promising restorer lines remains to be the major limitation for utilization of these lines.Identification of potential restorers acts as the main limiting factor for hybrid development in the Kashmir valley. Marker based screening for Rf3 and Rf4 fertility restorer genes can be helpful in rapid selection of restorer lines while dealing with the large quantity of genetic materials. In the present study, 100 rice germplasm were screened with the help of SSR markers, RM3148 and RM6100linked to Rf3 and Rf4 genes on chromosome 1 and 10, respectively. In total, 19 lines revealed the presence of both Rf3 and Rf4 genes. These lines amplified fertility restorer specific alleles for both the genes and may serve as potential restorers for obtaining heterotic rice hybrids. Further the germplasm lines were also evaluated for yield and quality traits.The present results would help in selection of suitable restorers along with preferred grain shape/size.

Background: The use of nutritional supplementation of the brewer&#039;s wort can be an interesting option to increase cell viability and yeast fermentability. </P><P> Objective: This study aims to evaluate the effects of the variables wort concentration and nutritional supplementation with palm oil in the production of beer in high-density wort. </P><P> Methods: The process effects were evaluated through the central composite rotational design of type 22 associated with the Response Surface Methodology (RSM). The fermentations were carried out using the commercial Saccharomyces cerevisiae yeast, lager type, at 15&#176;C. </P><P> Results: The mathematical models and RSM obtained were an efficienct strategy to determine the optimum fermentation point for the ethanol volumetric productivity (wort concentration of 20.90 &#176;P and palm oil content of 0.19 % v/v) and for the apparent degree of fermentation (wort concentration of 16.90 &#176;P and palm oil content of 0.22% v/v). There was a good correlation between the experimental values observed and predicted by the model, indicating that the fit of the model was satisfactory and it can be inferred that the increase of the wort concentration and the nutritional supplementation with the palm oil reached an ethanol volumetric productivity of 0.55 g/L.h and an apparent degree of fermentation of 50.20 %. </P><P> Conclusion: Therefore, it can be concluded that our study demonstrates that nutritional supplementation with palm oil is an alternative and promising option for the breweries to increase productivity. There are recent patents also suggesting the advantages of using alternative nutritional supplements in beverage production.

The rise of collaborative robots urges the consideration of them for different industrial tasks such as sanding. In this context, the purpose of this article is to demonstrate the feasibility of using collaborative robots in processing operations, such as orbital sanding. For the demonstration, the tools and working conditions have been adjusted to the capacity of the robot. Materials with different characteristics have been selected, such as aluminium, steel, brass, wood, and plastic. An inner/outer control loop strategy has been used, complementing the robot’s motion control with an outer force control loop. After carrying out an explanatory design of experiments, it was observed that it is possible to perform the operation in all materials, without destabilising the control, with a mean force error of 0.32%. Compared with industrial robots, collaborative ones can perform the same sanding task with similar results. An important outcome is that unlike what might be thought, an increase in the applied force does not guarantee a better finish. In fact, an increase in the feed rate does not produce significant variation in the finish—less than 0.02 µm; therefore, the process is in a “saturation state” and it is possible to increase the feed rate to increase productivity.

The agro-industrial sector consumes a significant amount of natural resources for farming and meat production. By 2050, population growth is expected, generating more demand and, consequently, more consumption of scarce resources. This challenging scenario is a concern of the European Commission, revealed in the Green Deal commitment and by the United Nations’ 12th goal of sustainable development. Thus, organizations must increase productivity and be more sustainable as soon as possible. Internet of Things (IoT) is introduced as a solution to facilitate agro-food companies to be more eco-efficient, mainly facing difficulties on farms, such as food loss and waste, best efficiency in management of resources, and production. The deployment of this technology depends on the stage of maturity and potential of implementation. To assess and characterize companies, with respect of IoT implementation, a survey was applied in 21 micro, small and medium agro-food companies, belonging to milk, honey, olive oil, jams, fruticulture, bakery and pastry, meat, coffee, and wine sectors, in the central region of Portugal. As results, this paper reveals the stage of maturity, level of sophistication, potential, opportunities, solutions, and barriers for implementation of IoT. Additionally, suggestions and recommendations to improve practices are discussed.
