The vehicle routing problems are one of the most studied combinatorial optimization problems in the logistics literature. In real life applications, all of the parameters of the problem may not be known. In this paper, we considered the capacitated vehicle routing problem with stochastic demands. Uniform and normal distributions were analyzed on customer demands to observe the stochastic nature of the problem. These methods were compared by using GAMS with different test problems which were taken from the literature. The clustering analysis including the K-means algorithm also applied on large-sized test problems.

The effect of the geomagnetic field on the ionosphere can be examined separately for the geomagnetically quiet and disturbed days. In the current study, the performance of the ionospheric models was evaluated for three different severe geomagnetic storms periods during the year of 2015, which was in the beginning of the descending phase of the 24th solar cycle. These three storms occurred during 17-18 March, 22-23 June and 20-21 December of year 2015 in which first one expressed as St. Patrick's Day geomagnetic storm. The relationship between Total Electron Content (TEC) was measured by Global Positioning System (GPS) and evaluated with NeQuick 2, IRI 2016, IRI Plas (without any input- “IRI Plas”) and IRI Plas TEC (with TEC input- “IRI Plas TEC”) global models at three Turkey IGS station namely Ankara (39.57 N, 32.53 E), Istanbul (40.58 N, 29.05 E) and Erzurum (40.39 N, 40.42 E) investigated. The comparison was made separately for pre-storm, during storm and post-storm by using the Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) metrics and symmetric Kullback-Leibler Distance (KLD) methods. Among the empirical models, IRI Plas TEC is generally present to be better results than other models for all storm processes. It can be stated that IRI 2016 is better in the storm return phase compared to other phases of the storm.","PeriodicalId":437889,"journal":{"name":"Muş Alparslan Üniversitesi Fen Bilimleri Dergisi","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126021437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tanyildizi","doi":"10.18586/msufbd.1195067","DOIUrl":"https://doi.org/10.18586/msufbd.1195067","url":null,"abstract":"Flexible pavements, also called asphalt pavements, are constituted of a bituminous surface course, subbase, and base layer constructed over a subgrade. The bituminous surface layer consisting of one or two layers transfers the traffic loads to the lower layers. The subbase and base layers of flexible pavements are constructed to support the surface layers and to distribute the loads from these layers to the subgrade safely. These layers must have the sufficient bearing capacity to support the surface layers and should also be resistant to detrimental environmental effects. In addition, the thickness of pavements is directly dependent on the bearing capacity of the subgrade. The materials used for the construction of the subgrade, subbase, and base layers in Turkey must meet the requirements specified in the Turkish Highways Technical Specifications. The previous specification published in 2006 was replaced by a new specification in 2013, which is still in effect. The current study compares the geotechnical parameters of the Highways Technical Specification published in 2006 and 2013 with a particular focus on flexible pavements. For an appropriate flexible pavement design, the importance of using high-quality and rigid materials that are more resistant to heavy loads, fragmentation, water sensitivity, and wearing effects of freezing and thawing is highlighted.","PeriodicalId":437889,"journal":{"name":"Muş Alparslan Üniversitesi Fen Bilimleri Dergisi","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132081614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized silver nanoparticles (AgNPs) were confirmed by color conversion and ultraviolet-visible (UV-visible) spectrophotometry. The appearance of a dark brown color and a UV absorption spectrum range at 440 nm confirmed the synthesized silver nanoparticles. The antimicrobial activity of silver nanoparticles synthesized from the leaf of P. vulgaris; S. aureus 25±1, S. epidermidis 20±1, P. aeruginosa 20±1, A. hydrophila 21±1, C. albicans 25±1, C. tropicalis 25±1, C. parapsilosis 22±1 and C. glabrata 20±1 mm zone diameter was determined. The most antimicrobial effect of P. vulgaris leaf aqueous extract; S. aureus 20±1, S. epidermidis 18±1, A.hydrophila 15±1, P. aeruginosa 12±2, C. albicans 18±1, C. glabrata 18±1, C.tropicalis15±2, and C. parapsilosis 15±2 mm zone diameter was revealed. The presence of flavonoids, terpenoids, protein, and carbohydrates was found to be higher in silver nanoparticles synthesized in the flower part of P. vulgaris, according to phytochemical screening. While saponins were detected in P. vulgaris root extracts, tannins and protein were detected in the leaf extract. The flower had the highest total phenolic extract content of the silver nanoparticle (29.08±0 mg GAE/g DW), while the leaf and root had the lowest total phenolic content of 9.06±0.5 and 8.64±3.3 mg GAE/g DW, respectively. The flower had the highest total phenolic extract content of the plant aqueous extracts (25.10±0.2 mg GAE/g DW), while the leaf and root had the lowest (8.28±0.5 and 5.20±0.0 mg GAE/g DW, respectively).The DPPH (1,1-Diphenyl-2-picrylhydrazil) assay was used to assess free radical scavenging activity. The antioxidant activity of AgNPs biosynthesized using P. vulgaris flower extract was 90.6 %, while P. vulgaris flower aqueous extracts were 86.3 %. \u0000This can be concluded that silver nanoparticles synthesized using P. vulgaris flower extract are useful in the preparation of pharmacologically useful drugs.","PeriodicalId":437889,"journal":{"name":"Muş Alparslan Üniversitesi Fen Bilimleri Dergisi","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121212526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
