However, the engineering practice shows that high percentage of cracks and failures in structures are related to soil settlement reasons, non-uniform soil settlement for example. Geotechnical engineers developed many methods to calculate the settlement of soil, but the majority of these methods are geotechnical engineering oriented, and standard structural engineer may struggle using them. Therefore, because of the importance of finding the approximate soil settlement in many cases during the design process or during the implementation of the structure, this study gives simple equations that can predict the soil settlement with acceptable accuracy, by creating a relationship between the soil settlement and the displacement of the structure. The targeted equation will allow us to find the soil settlement from knowing the approximate displacement of the structure . Such an equation gives a conceptual value to be used in 3D analysis of structures using computer programs like SAP2000 and ETABS. The targeted structure in this study is a simple one rectangular column and footing structure.","PeriodicalId":274683,"journal":{"name":"An-Najah University Journal for Research - A (Natural Sciences)","volume":"1105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131908649","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}

In this study, 480 eggs were collected in two different periods from various retail markets, both Palestinian governorates Tulkarm and Jenin. All collected eggs were evaluated for their safety and external and internal quality. The results showed that about 40.0% of the collected samples had eggshell abnormalities. A high variation in the egg's weight was detected in the eggs collected from Tulkarm. According to the Haugh unit, the results indicated that the most collected eggs were in class B. The average yolk color score of all periods in both governorates is around 8. Some eggs had yolk pH values of more than 6.6 in both governorates. Most collected eggs in both periods and governorates were fresh according to the yolk index. Escherichia coli was present in the eggshell collected from Jenin governorate. Meanwhile, Salmonella enteritidis was present in Tulkarm governorate. In conclusion, this study confirms that grading, cleaning, and cooling is not practiced before the sale, which may lead to microbiological health hazard to the general public. Thus, this study recommends avoiding eating raw or undercooked egg yolks and whites or their products.","PeriodicalId":274683,"journal":{"name":"An-Najah University Journal for Research - A (Natural Sciences)","volume":"95 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126114923","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}

To address these challenges, hydrological modeling has been used to gain understanding of the hydro-logical systems and to provide the required inputs needed for sustainable water resources management. Further-more, coupling hydrological models with climatic models provides even more understanding of the influence of the climatic parameters on hydrological processes and systems, and hence on runoff generation mechanism. In this research, WRF-Hydro (the Weather Research Forecasting model coupled with the Distributed Hydrologic Modeling System) was used for streamflow forecasting in the Faria catchment. Faria (320 km2), located in the northeastern part of the West Bank, Palestine, is a gauged catchment where rainfall and streamflow data are available for more than ten years. This study aims to assess the functionality of the WRF-Hydro to predict reliable streamflow hydro-graphs at the upper part of the catchment. Additionally, a new channel loss function was incorporated into WRF-Hydro to model the amount of water lost in the ephemeral (loosing) streams of the catchment. Hence, the rainfall and streamflow data for the rainy season; 2017-2018.were utilized. Results indicate that WRF-Hydo model is well functioning, but model calibration and validation is still required to further improve the model performance.","PeriodicalId":274683,"journal":{"name":"An-Najah University Journal for Research - A (Natural Sciences)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127918756","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}
