The whole study was conducted for the Municipality of Prizren and aims to to determine the effect that the population density has on land surface temperature (LST). All this was achieved through the connection of land surface temperature (LST) and population density. The free Landsat 8 satellite image downloaded from the United States Geological Survey website was used and then processed using GIS...
The article showed the result of investigation of the length of hydraulic jump in trapezoidal channel. In this study, the basic factors that affect the length (Lj) and roller length (Lr) of hydraulic jump were investigated by physical trapezoidal channel’s model. The experiment carried out in purpose to establish a new empirical equation for calculating the roller length (Lr) of the jump in the horizontal...
The study assesses the pollution discharged from 251 wastewater treatment plants (WWTPs) throughout the Odra river basin in the Czech Republic. The development of pollution production over a period of 15 years (2004–2018) together with a number of WWTPs in the Odra river basin were analyzed. The Grey Water Footprint (GWF) of discharged pollution was determined both in terms of individual size categories...
A study was conducted to explore the effect of palm oil boiler ash (POBA) on foamed concrete by varying the percentage of POBA over sand quantities (0, 4, 8 and 12%). This paper primarily discusses the water absorption test, uniaxial compressive strength, and dry density findings. It indicates that substituting sand with POBA greatly enhances the strength of foamed concrete. When the quantity of POBA...
The hospitals close to the residences can make problems for the environment as a consequence of sewage drained into the water stream. Sequencing batch biofilm reactor (SBBR) offers advantages for treating sewage; such as simple operation, flexible process, and cost-effective. The laboratory bench-scale experiments were carried out treating hospital wastewater (HWW) of one of Basrah hospital city by...
This paper deals with an analysis of causes that lead to the change in price (value of construction costs) of road infrastructure projects in selected phases of the building structure life-cycle, more specifically procurement and construction phases, with the aim to refine the price estimation in the Estimated Value determination phase. The sample of regional road construction projects in the South...
An increase in Indonesian forest fires has infuriated Malaysia and Indonesia, where residents are inhaling smoke from peat and trees burned hundreds of miles away. The global COVID-19 lockdowns caused carbon monoxide (CO) emissions decreased seen over Malaysia and Indonesia regions. The main objective of this study is to investigate the CO distribution over Malaysia and Indonesia, within the period...
This article focused on comparing the development of the price level of the water and sewerage charge rates in the regions of the Czech Republic to the development of macroeconomic indicators expressing the performance of the individual region. The following were selected as macroeconomic indicators: gross domestic product, gross domestic product per capita, net disposable income of households, net...
Girders with corrugated steel web are preferred and widely used in recently constructed bridges and industrial buildings. Sandwich core girders with corrugated web are constructed by adding two plates (skins) to the corrugated web. This study aims to investigate the shear span-to-depth ratio impact on the performance of sandwich core steel girders with corrugated web. Three span-to-depth ratios (a/d):...
Fiber’s addition to concrete mixture attracts researchers to determine the effect of fiber type on durability properties of hybrid performance concrete. In the present work, steel and polypropylene fibers are used in hybrid form in the experimental program. The objective of this paper is to investigate the mechanical properties of hybrid fiber reinforced concrete subjected to four various media: air,...
Damaged tires or ended-life tires represent a difficult problem due to their ability to sustain for a long time which are not able to be dissolved easily. Present study focuses on the ability of using the damaged tires strips (DTS) in the field of structural engineering as an innovative reinforcing material used additionally with the main reinforcement. The adopted technique in the present work represents...
Chlorpyrifos-methyl (CM) is a broad-spectrum organophosphate insecticide, which is widely used in pest control. In this research, the isolation, and biochemical and molecular identification of bacterial strains obtained from three soils located in northeastern Algeria were carried out, as well as the evaluation of their ability to grow in the presence of CM. Out of 48 bacterial isolates between Gram-negative...
Applied element method (AEM) is a recently displacement-based structural analysis method. It provides the benefits of both the finite element method (FEM) and the discrete element method (DEM). This method relies on those structures are segmented into rigid elements linked by normal and shear springs. In this paper a brief note of the AEM is given. Then, using the AEM, a 2D MATLAB open source program...
The influence of styrene butadiene rubber (SBR) or low-density polyethylene (LDPE) polymers on the characteristics of local asphalt binder was analyzed to characterize the rheological properties. The results indicated that the SBR or LDPE increased the softening point. The softening point was enhanced by around 35% when 9% of SBR was used in comparison to the unmodified asphalt, while there was a...
The construction activities are based on structural concrete, which is one of the most commonly used materials. The fundamental aim of using lightweight concrete (LWC) was to reduce the concrete self-weight of the structure parts. As a result, LWC has been used successfully in a variety of installations for several years. In this paper, the mechanical properties of concrete made with lightweight expanded...
The study aimed to establish the relationship between values and people’s preferences for sustainable improvement in Nigeria’s indigenous housing context. The relationship was tested in SEM using ordinal survey data obtained between February and March 2022 with 241 valid samples. The mainstream values were statistically validated using CFA while the relationships were generated in the SEM. Results...
This study simulates and assesses the hydraulic features and residual chlorine in Al-Najaf city’s water supply network using WaterGEMS. Field and laboratory work was done to determine pressure heads, velocities, and chlorine residual. Constructed model was validated using field data. Values of RMSE were between 0.08 and 0.1, and 0.05 and 0.06 for pressure and residual chlorine, respectively. The examination...
This study shows the results of long-term inland water monitoring using Sentinel-2 data for Głuszyńskie Lake in the years 2015–2022. Four water quality parameters: biological oxygen demand (BOD), dissolved organic carbon (DOC), chlorophyll concentration (CHL) and electrical conductivity (EC) were calculated according to formulas found in the literature. The results were validated based on measurements...
Research and development help improve the reliability of EVs range, battery capacity, and trouble-free charging (or service). These factors affect consumers’ interest in EVs. The quality of EV use can be supported by a modern technology called Energy Assistant (EA). The task of EA is to inform the driver about the current range, the necessity to recharge the batteries, and so on to avoid a critical...
Increasing waste recycling has become an essential process in the construction industry due to the environmental and economic advantages, such as minimizing waste in landfills, saving natural resources, and decreasing pollution. Crushing and sieving waste from standard compression test cubes is used to produce the recycled concrete aggregate (RCA). A set of standard concrete cylinders, cubes, and...
