Abstract: Agricultural mechanization is an essential factor influencing agricultural output and the profitability of farming activities. The influence of agricultural mechanization on agricultural production in Lagos State, where the majority of the farmers use modern technologies for their farming operations, was investigated. The investigative research approach method was employed to retrieve information from farmers through a structured questionnaire. A five rating scale questionnaire was utilized for the respondents to show their level of agreement or disagreement. The percentage was used to analyze the respondents' bio-data. At the same time, the mean was employed to answer the research questions. The null hypotheses were tested using Chi-square statistics at 0.05 significant levels. The results revealed that agricultural mechanization increased the cultivated land, crop yields, and farmers’ income with cumulative means of 2.34, 1.07, and 1.44, respectively. Socioeconomic characteristics, available technology, and government policies influenced agricultural mechanization with cumulative means of 1.93, 1.24, and 1.79, respectively. The entire six hypotheses were rejected based on the results of the Chi-square statistics with the calculated X² values of 8,989.09, 473.59, 3,977.42, 2,192.63, 226.07 and, 1,878.05; and critical X² values of 46.19, 46.19, 36.42, 31.41, 21.03, and 31.41, for the significant effect on the size of land cultivated, crop yield, farmer’s income, socioeconomic characteristics, available technology, and government policies respectively. The study showed that agricultural mechanization had a significant influence on crop production and farmers’ income. Therefore, there is a need to improve the available technologies and formulate and implement policies to make agricultural mechanization accessible and sustainable.

Abstract: Nowadays, the type of foamed concrete performs a group of cemented composite materials that can compete with conventionally used autoclaved aerated concrete. Improving microstructure of the foamed concrete by inventive mixing technology allows to homogenizate the mix of foamed concrete. This original research is applied to inspection on mixing technology of foamed concrete by using a planetary ball mill. The objective of this paper is to clarify the correlation between physical-mechanical properties and intensive mixing time.

Abstract: The article addresses the problem of noise from the perspective of protected building space near the construction. If they are near a building already populated, the residents should not be exposed to elevated noise burden, and according to Government Regulation No. 272/2011 of 24 August 2011 on health protection before adverse effects of noise and vibrations, which are set noise limits. In the process optimization production planning is therefore necessary to address the areas of in-situ noise, its creation, modeling, design methodologies to assess the overall noise at the site. The Article analyzed the issue introduction of new approaches when optimizing for the site and the necessity aspects of noise pollution site in construction technological preparations for the construction. The article defines in detail the sources of noise during construction, dealing with modeling of site noise sources and the value of the protected space structures. It presents examples of noise studies, where captured effect of noise on the nearest places protected sites and residential areas. Presents the methodology of work with the values of the inputs and outputs when working with software support.

Abstract: In the recent years, antibiotics and heavy metals have become common pollutants in soil. Plant-microbial remediation is promising for the management of antibiotics and heavy metals pollution in soil. This paper talks about the mechanization of plant-microbial remediation, finds the advantages and disadvantages about plant-microbial technology, summarizes the method of selection of the plant and microbial, influential factors, and discusses the future research priorities of plant-microbial remediation.

Abstract: Airing on-field, airing on-bed and airing on-machine are the usual way on production of Luzhou-flavor liquor. The essay makes a brief introduction about the three airing ways, at the same time it researches the effect of different airing ways on fermented grains and pits fermentation. As the way of mechanization airing, the machine of airing absolutely meets the technology demand on the production of Luzhou-flavor liquor, moreover, it has saved labor. Furthermore, it not only benefits for the stability and uniformity of fermented grains, fermenting, but raises productivity of liquor.

Abstract: Earth as a construction material is being announced as capable to answer the construction sectors demands with considerable reductions on environmental impacts. It is an abundant raw material, commonly available at the construction site, which requires low energy consumption to be produced or transformed and which also doesnt need to be fired, what means that its production emits very small amounts of CO₂. In terms of results for the built environment, it may provide excellent thermal and acoustic comfort, besides contributing to regulate the environments humidity. At the end of its cycle the material can be discarded bringing no harm to soil and water, it is rapidly absorbed by the environment conversely, it can be recycled by turning it into mud again, so it can be used to prepare new construction elements. However, in Brazil and in many other developing countries, the application of the earth construction technologies usually occurs as handmade work. Particularly on the adobe production, the blocks are mostly molded one by one or in pairs, depending on the type of the molds, aiming to accomplish a production of thousands of unities. The soil used for block molding has to be in a plastic consistency and, to achieve that quality, intensive human effort is generally employed. Considering those difficulties this paper intends to present an initial roll of machines used on production processes of Brazilian construction sector, and other industrial sectors, that can be integrated to adobe fabrication procedures to help mixing the mud. From the collected information, a preliminary evaluation will be formulated revealing which of the equipment contribute effectively for the comfort and safety of workers. Another factor that may be considered for this selection is the investment amount needed. As high costs interfere with the control of the means of production, the workers may have their access to this condition denied, situation that affects the possibility of social advances that can be promoted by the appliance of adobe.
