In this paper, we examine existing literature on the way that the number of blades of a wind turbine affects its efficiency and power generation. A wind turbine blade is an important component of a clean energy system because of its ability to capture energy from the wind. The power that a wind turbine extracts from the wind is directly proportional to the swept area of the blades; consequently, the blades have a direct effect on power generation. The number and configuration of the blades is very important because it affects the speed and efficiency of turbine. Unfortunately, as the number of blades increases, so does the slipstream effect. Too few a number of blades results in poor efficiency and thus inadequate performance. Too large a number of blades increases weight and production cost. The correct number of blades is important to fit the generator performance curve to optimize overall turbine performance and efficiency.

View article, Correlation between conductivity and total dissolved solid in various type of water: A reviewPDF, Correlation between conductivity and total dissolved solid in various type of water: A reviewConductivity (EC) and total dissolved solids (TDS) are water quality parameters, which are used to describe salinity level. These two parameters are correlated and usually expressed by a simple equation: TDS = k EC (in 25 °C). The process of obtaining TDS from water sample is more complex than that of EC. Meanwhile, TDS analysis is very important because it can illustrate groundwater quality, particularly in understanding the effect of seawater intrusion better than EC analysis. These conditions make research in revealing TDS/EC ratios interesting to do. By finding the ratio value, TDS concentration can be measured easily from EC value. However, the ratio cannot be defined easily. Previous research results have found that the correlation between TDS and EC are not always linear. The ratio is not only strongly influenced by salinity contents, but also by materials contents. Furthermore, the analysis of TDS concentration from EC value can be used to give an overview of water quality. For more precision, TDS concentrations need to be analyzed using the gravimetric method in the laboratory.

View article, Urban heat islands: a review of contributing factors, effects and dataPDF, Urban heat islands: a review of contributing factors, effects and dataUrban Heat Island (UHI) is one of the most serious difficulties that humans have faced in the twenty-first century resulted due to urbanization and industrialization. The main causes of UHI are the vast amounts of heat produced by urban structures, which solar energy should be used and re-radiated as well as anthropogenic heat sources. The two heat sources cause an urban area’s temperature to rise in comparison to its surrounding areas, which refers to a phenomenon of the urban heat islands. Large cities and diverse economic activities face even more serious difficulties. This paper defined the concept and types of UHIs. This paper explained a comprehensive review of the phenomenon of UHI from its first appearance with regard to causing factors, its influences on people’s lives and the urban environments, and widely used data for measuring and evaluating the intensity of UHIs. The finding of most studies mentioned that UHI values are different from city to city based on land-use changes. It is revealed that an increasing trend occurred mainly because expand in built-up areas and a reduction in green cover. Also, a number of studies showed that the UHI intensity was low during summer afternoons and high during winter nights in many places around the world.

Coal deposits play a major role in energy production, and at the same time, coal mining causes adverse environmental effects. For this reason, the article is devoted to the study consequences of coal mining on water contamination and soil conditions. The investigation results show that coal mining causes dangerous and harmful particles to reach the surface of the water, degrades the soil, and causes chemical exposure. Hydrology and water quality throughout the mining lifecycle are influenced by such consequences, which can be observed across mining regions and under different extraction methods. In this regard, there exists a need for effective strategies and implementing best practices for mining operations, adopting preventive measures for acid mine drainage, and advanced water management techniques. Also, the experience of effective environmental management is discussed. Mining reclamation plans, adherence to specific standards, and the role of rocks selection in reclamation success are discussed. Considering the above balancing energy needs with sustainable environmental practices is crucial to ensuring the coexistence of mining and global water resources.

Leaves ExtractsKatuk is widely popular with its benefits for breastfeeding mothers. Katuk is also known as a plant with a high antioxidant content. This study aims to determine the effect of using variations in the ethanol concentration as an extracting solvent in producing Total Phenolics Content (TPC) and Total Flavonoids Content (TFC) and their activities in reducing DPPH free radicals. The dried katuk leaves were extracted by cold maceration method. The solvent used for extraction is ethanol with 3 variations in concentration: 50%, 70%, and 96% (absolute ethanol). TPC and TFC were determined by colorimetric method using a UV-Vis spectrophotometer. TPC was stated to be equivalent to gallic acid, while TFC was stated to be equivalent to quercetin. DPPH free radical scavenging activity was measured based on the IC50 value. The results showed that Katuk leaf extract produced from 50% ethanol solvent was able to produce TPC (42.18 ± 0.30 mg GAE / g), TFC (11.18 ± 0.38 mg QE / g) and reduction activity against DPPH radicals (IC50 = 88.33 ± 3.53 ppm). These were higher than ethanol with other concentrations. However, various things need to be considered when using this solvent given the high water content in the solvent.

Thus, basic knowledge of starch properties is important. This research aimed to evaluate the physical and thermal properties of various potential starch, i.e. corn, cassava, and potato starch. Granule size, thermal property, and functional group of starch were determined by optical microsopy, DSC, and FTIR, respectively. Our results demonstrated that the properties of starch (e.g. granule morphology and thermal property) varied according to its different sources. Potato starch has a bigger granule size and lower gelatinization temperature compare to corn and cassava starch. This implied that the granule size of starch affected gelatinization temperature. The larger the granule size, the more easily the starch to be gelatinized.

Different levels of integration can be envisaged, ranging from a BOQ export (Bill Of Quantity) based on the BIM-model to import in native LCA-software, up to a real time LCA-calculation within the native design environment, giving real time feedback on design decisions, or alternatively utilizing the standardized BIM-information exchange format IFC. Based on the evaluation of existing tools, this paper focuses on the possible workflows for the integration of LCA and BIM. A comparative analysis between these different information flow structures exposes their advantages and disadvantages, depending on the design phase they are used in and the availability of generic, product-specific or manufacturer-specific LCA-data.
