Its impacts may also be serious and costly. This study, considering the fact that drought is a significant natural disaster, aimed to investigate the characteristics of drought in the Küçük Menderes River Basin. Among several drought indices, the Standardized Precipitation Index (SPI) and Streamflow Drought Index (SDI) were used for drought analysis. SPI and SDI were applied to the monthly precipitation data of Selçuk and Ödemis meteorological stations with nos. 17854 and 17822, and to the monthly flow data of Selçuk and Bülbüller flow gauging stations with nos. E06A001 and D06A012, respectively. Drought classes for each month were obtained through the referred drought indices. Using the drought classes, meteorological and hydrological droughts were statistically investigated at a regional scale by determining the drought classes’ occurrence probabilities, the expected residence time in each drought severity class, the expected first transition time, and the drought class with the highest probability of occurrence in the near future.</span></div> Serbay Tatar Ebru Eris Copyright (c) 2022 Scientific Research Communications 2022-07-28 2022-07-28 2 2 10.52460/src.2022.006 Application of the WASP Model for Assessment of Aeration Impact on Water Quality of Porsuk River, Turkey <p>Porsuk Stream is the longest branch of the Sakarya Basin which originates from Murat Mountain and bypasses the provinces of Kutahya and Eskisehir. Based on recent increasing pollution concentrations reported in the literature, the main river is experiencing problems with decreased water quality. In this study, hydrodynamics and water quality parameters are simulated in the Porsuk River via the application of the Water Quality Analysis Simulation Program (WASP) using the available flow and meteorological data. After the validation of the hydrodynamics along the main river, water quality parameters are simulated using the eutrophication module. Simulation of dissolved oxygen concentrations pointed out hypoxia, especially at two locations; Kutahya-Reservoir1 and Alpu-Guroluk segments where dissolved oxygen values stayed well below the standard limits throughout the year. As a mitigation option, aeration applications at these two stations are proposed and the effects of aeration on the simulated parameters of dissolved oxygen, phosphorus and nitrate concentrations are investigated. Aeration at two segments has significantly improved the dissolved oxygen concentrations (from ~3 mg/l to &gt;14 mg/l) whereas it has a more subtle effect on nitrate and phosphorus concentrations.</p> Emre Dumlu Sebnem Elci Copyright (c) 2022 Scientific Research Communications 2022-10-28 2022-10-28 2 2 10.52460/src.2022.008 The Conceptual Study of Non-Stick Cookware Coatings and the Effect of Some Corresponding Additives on Their Performance <p>In this study the effect of some additives including Alumina, B4C and different types of SiC on glossiness, impact resistance, pencil hardness, conical bent resistance, corrosion, humidity and chemical resistance of non-stick coatings were studied. The results revealed that glossiness of the coatings decrease by addition of the additives but the overall resistance of the coatings grow by adding these substances among which boron carbide additive had the best effect on the coating general performance.</p> Jabir Ismaeili Jigneshkumar Patel Bikem Övez Copyright (c) 2022 Scientific Research Communications 2022-08-24 2022-08-24 2 2 10.52460/src.2022.007 Effects of Bio-Particles on Mechanical and Quasi-Static Punch Shear Behaviors of Glass/Epoxy Composites <p>In this study, the effect of acorn powder reinforcement at different percentages on the mechanical and quasi-static penetration behavior of glass fiber reinforced composites was investigated. Reinforcement materials used are woven E-glass fiber and cleaned acorn micro powders. Powders were cleansed from impurities with a sodium hydroxide solution. Cleaned powders were mixed with resin by using a mechanical mixing method. Thereafter, resin mixture was applied to glass fibers with hand lay-up method and composite plate was produced by vacuum bag method. Quasi-static penetration tests were performed at room temperature as well as mechanical tests. While 1, 10 and 20 mm/min were selected as quasi-static penetration test speed, tension, compression and three point bending tests were selected as mechanical tests. Force and energy test results of quasi-static penetration tests of composites were compared with each other. Additionally, tensile, compressive and flexural strengths of the composites were investigated.</p> Halis Kandas Okan Özdemir Copyright (c) 2022 Scientific Research Communications 2022-12-10 2022-12-10 2 2 10.52460/src.2022.010 Biological Activities of Plant Ethanolic Extracts from Asplenium trichomanes (Maidenhair spleenwort) and Lagenaria siceraria (Bottle gourd) <p>Plant is commonly known as one of the main dietary sources of the human being. Many plant-derived compounds have been used as drugs, either in their original or semi-synthetic form. There are also several plant extracts or “phytomedicine” in clinical trials for the treatment of various diseases. Plant-derived compounds will still be an essential aspect of the therapeutic array of medicines available to the physician, particularly with the availability of new hyphenated primary analytical methods by determining biological activities of medicinal plants. The ethanolic extracts of two creeper plants namely Asplenium trichomanes (Maidenhair spleenwort), Lagenaria siceraria (Bottle gourd), originated from different geographical part of the world were chosen to be determine its antimicrobial, antioxidants, anti-inflammatory and UV radiation absorbance activity which is mainly characterize the anticancer activity which is nowadays become the most fatal disease. Such kind of biomedical and biotechnology approaches have been aimed to eradicate naturally such illness which is the main objective of this work. The present study shows that different ethanolic leaf extracts have an important and necessary antioxidant and anti-inflammatory properties with UV absorbing activity at UV–A region. These results show that Asplenium trichomanes and Lagenaria siceraria will be potential natural sources of antioxidant and anti-inflammatory activity. They could have greater importance as therapeutic agents in preventing or treating oxidative stress and inflammation related disorders, such as cancer and other health disorders. While the negative result of the antimicrobial activity of most of both ethanolic extract is considered as a positive result depending to main purpose of future work. Because it shows that extracts will never upset the gastric flora, in which they must be applied safely away from any harmful reaction and allergic or side effects for the living organism.</p> Mohamed Chanfiou MKOUBOI Nasar Rahman J.
