RESUMO: Este trabalho apresenta um mapeamento e análise das manifestações patológicas que intervêm nos revestimentos argamassados externos de quatro edifícios residenciais constituídos de múltiplos pavimentos, situados no município de Presidente Prudente – SP, assim como a identificação de suas prováveis causas, o que permitiu reconhecer se as origens da maioria dos problemas patológicos provêm de falhas ou indefinições de projetos, qualidade do reboco, falhas de execução e, de falta ou falhas de manutenção nos sistemas estruturais e em elementos construtivos, durante o uso destes edifícios. Os resultados obtidos possibilitaram classificar os efeitos e as causas dos problemas patológicos identificados nos revestimentos argamassados externos dos edifícios objetos de estudo, bem como desenvolver quadros comparativos para sua análise envolvendo os efeitos ocorridos, a provável origem e, a intercessão da temperatura e da umidade nas causas das manifestações patológicas identificadas nos edifícios. Diante do exposto, as manifestações patológicas nos revestimentos argamassados estudados foram concedidas ao desatento de ações e a não consideração de agentes agressivos, levando a constatação de que as anomalias identificadas são provenientes de omissões, lapsos no detalhamento e/ou intercessões de projetos. Por fim, este estudo contribui com dados que servem de alerta aos profissionais da área de construção civil. ABSTRACT: This paper aimed to mapping and analyze the pathological manifestations that interfere in the external mortar coverings of four residential buildings with multiple floors, located in the municipality of Presidente Prudente – SP – Brazil, as well as the identification of their probable causes, which allowed to recognize if the origins of the majority of the pathological problems arise from project failures or inaccuracies, plaster quality, failures of execution and, faults or failures of maintenance in structural systems and in constructive elements, during the use of these buildings. These results made it possible to classify the effects and causes of the anomalies identified in the external mortar coverings of the buildings, as well as to develop comparative tables for their analysis involving the effects, the probable origin and the influence of temperature and humidity on the causes of manifestations observed in buildings. In view of the above, the pathological manifestations in the mortar coatings studied were attributed to the negligence of actions and the non-consideration of aggressive agents, leading to the finding that the anomalies identified are due to omissions, lapses in detail and / or project interferences. Finally, this study contributes with data that serve as a warning to professionals in the area of civil construction.

Soybean wastewater is a kind of nutrients wastewater. Using yeast to treat this kind of wastewater can not only degrade high concentration organic pollutants, but the yeast cell itself also can be harvest and realize the resources recycling. In this work, the feasibility and the optimal conditions of using yeast to treat soybean wastewater were investigated. Results showed that the initial COD and hydraulic retention time were the critical factors influencing COD degradation. Under 28 °C and with the initial soybean wastewater of 4800 mg/L, usingCandida utiliswith 20% of inoculums dosage could realize the higher reduction of the concentration of COD. And after 18 h’s treatment with rotating speed of 160 rpm, the COD removal could reach to 90%. The yeast wastewater treatment technology has the prospect of resources recycling. Besides, the pH value is very important for yeast to treat soybean wastewater.

The yield of proteolylic hydrolysis for spent brewer’s yeast by protease and aminoacid contents of hydrolysates (the main  factors influencing in taste of hydrolysed product) depends on factors influencing in catalytic activities of enzymes as temperature, pH value, type of used  enzymes and ratio enzyme/substrate. With the purpose to hydrolyse the spent brewer’s yeast for food application, bitterness of hydrolysate takes the firth consideration, and than the yield of hydrolysing process plays economic role. In this paper, it is dealt with determination of optimal conditions to obtain the highest yield of hydrolysis process and the lowest bitterness of hydrolysate (the bitterness is determined by sensory evaluation, expressed equivalently with concentration of quinine). Response surface methodology (RSM) was used to determine optimum condition for batch proteolytic hydrolysis of spent brewer’s yeast. The influencing factors were investigated as temperature (X1): 40 oC–60 oC; pH (X2): 6.0–9.0, ratio E (flavourzyme)/S (X3): 5–10 U/g and hydrolysis time (X4): 6–9 hours. The experimental responses including degree of hydrolysis (Y1) (%) and bitterness of hydrolysate (Y2) (μmol quinine/ml) are performed in second-degree model. The optimal conditions for obtaining high degree of hydrolysis and low bitterness are determined: Ratio of enzyme mixture (alcalase 7.5 U/g and flavourzyme 8.5 U/g), pH 7.5, hydrolysis temperature at 52oC and hydrolysis time 9 hours. Under the optimal conditions, the actual values obtained for the yield of hydrolysis was 40.81  ± 0.044 % and the bitterness equivalently with concentration of quinine was 16.37 ± 0.03 μmol quinine/ml.

The purpose of the article is to analyze the state of housing construction in the Kharkiv region and identify factors influencing the dynamics of its development. It is noted that the housing problem remains extremely relevant for the Kharkiv region where there is a large delayed demand for housing. Housing construction accelerates the growth of the gross domestic product of the region, employment of its population, growth of budget revenues. Factors influencing the amount of housing built are not constant and require periodic analysis. Statistical data of housing construction in Kharkiv region are investigated. It is noted that the area of housing commissioned has decreased in recent years. In 2012, half of the total area of residential buildings commissioned in the Kharkiv region fell on the city of Kharkiv. The last three years the area of residential buildings built in other cities and towns of the region is 17–30%. The leaders in housing construction among the cities of regional significance in different years were: Lyubotyn (2014), Izyum (2015, 2019), Kupyansk (2016-2017) and Chuguiv (2018). Among the districts, the most active housing construction is carried out in Kharkiv and Derhachiv districts. It is noted that the volume of construction work performed by enterprises of Kharkiv region in January-June 2020 amounted to 8.9% of the national volume, but the pace of construction of residential buildings decreased by 13%. The index of residential construction products for the first half of 2020 compared to the first half of 2019 amounted to 88%. It is determined that the number of commissioned housing primarily on the amount of capital investment in the region and other factors influencing the dynamics of housing development, such as the socio-political situation in the country, the state of the economy, the availability of mortgage lending and others. The housing programs operating in the Kharkiv region to provide the population with their own housing are considered.

The article identifies the main patterns of construction of Boyko residential buildings, which are based on an archaic three-part plan. It was found that Boyko's three-chamber dwellings existed in three variants, where the oldest type is considered to be one in which the dwelling cage is located in the middle, and the hayloft and pantry - on the sides of the dwelling. Based on measurements of existing buildings, analysis of literature and archival drawings, an ideal model of traditional three-chamber Boyko housing was created and it was substantiated that the idea of an archaic three-chamber house was based on the laws of the golden section. However, in practice, most houses had minor deviations from this rule, which were due to the different width of the ancillary premises and the violation of the proportions of the living space. The construction of traditional residential buildings of the Boyko construction school meets four basic rules: symmetry or the desire for symmetry in the construction of plans and facades with a possible asymmetrical arrangement of individual elements and parts of the house; staticity of the whole volume of the building; balance of the main elements of the house; variety in the use of details and decor. Despite the typical plans and ancient rules of the general compositional construction of houses, the masters sought uniqueness and artistic expression with the help of details. The location of the yards was influenced by the terrain and local natural conditions. It is revealed that the identity of architectural and natural forms is the main principle that makes it possible to harmoniously link static architectural forms with constantly changing natural. The predominance of the sloping lines of the silhouette of the house over the vertical lines provided an organic connection with the environment.

The successful development of a territory as a tourist destination is not always associated with a variety of recreational resources. In the modern conditions of informatization, of great importance is a favorable image of the territory, which helps to promote the created recreational center. Our study aims to identify the factors that have contributed to the recreational development of the Finnish city of Kouvola, which, in the absence of significant recreational facilities, is one of the most important tourist destinations in southeastern Finland. We have analyzed the features of the economic and geographical position of the city, and identified the most attractive objects of tourist interest based on the content analysis of reviews about Kouvola on tourist Internet portals. We have also examined how careful attitude to the industrial history of the city made it possible to create new attractive recreational objects. The following factors have been found among those making Kouvola attractive for tourists: the border position of the city and its location at the intersection of important transport routes, as well as the presence of interesting recreational facilities in the adjacent territories and large shopping centers in the city itself. Consequently, Kouvola is used as an ‘entry point’ into adjacent territories with richer recreational potential. At the same time, the most important factor in the tourism development of Kouvola is no t the position near the border, but the location on the way of tourist flows. On the other hand, the tourist infrastructure created in the city contributes to the fact that tourists also use it as a point of main stay. Analysis of the recreational development experience of such places can be applied for planning tourism development of geographically similar territories.
