A plant affiliation of Brassicaceae family. The objective of this study was to phytochemically analyzing of France purchased Hybrirock and local pactol seeds by Gas chromatography mass spectrophotometry and comparison of their essential oil components in relation with previous works. The French purchased hybrirock seeds and local pactol seeds were planted in Gerda rasha field Grdarash field, College of Agriculture, Salahaddin University-Erbil and seeda were stored for later chemical analysis. The GC-MS detections showed that the most abundant phytochemical constituents were E, E, 2, 4-Decadienal (22.3% for Hybrirock seed oils and 15.64% for pactol seed) and Hexanal (18.37 for hybrirock seed and 8.72% for Pactol seed oils), followed by 2-Undecenal (7.66% for hybrirock seed and 14.27% for pactol seed oils). Our study demonstrated that both studied genotypes of same species contained different important chemicals and beneficial polyunsaturated fatty acids however glucosinolates were significantly higher in pactol seeds in compare with hybrirock seeds, making pactol seeds less edible and more suitable as nematicides or as precursor of Bio-fuels and the two tested genotype seeds have shown sufficient hydrocarbon content which can be used as a substitute of petrol hydrocarbon. While hybrirock seeds with higher fatty acid contents and lower glucosinolates possessing more edibility features to be used as food products and medical agents.","PeriodicalId":7515,"journal":{"name":"Al-Mustansiriyah Journal of Sciences","volume":"12 1","pages":"65-71"},"PeriodicalIF":0.0,"publicationDate":"2020-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87385924","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}

They had unmistakably negative effects on people, plants, creatures, and distinctive monetary segments. Especially in urban areas, where most people are living, their prosperity, productivity and wellbeing were influenced, which even caused a generally high death rate. This is the reason an enormous intrigue still exists to analyze heat waves in the past by utilization of measurable strategies. As an examination on heatwaves isn't accessible for the domain of Baghdad city up to now, a review examination was directed. Its primary points were (1) to decide the recurrence of heatwave scenes for this nation and (2) to analyze their spatiotemporal dissemination, term, and force. Based on Baghdad city, from the Iraqi Meteorological Organization and Seismology and Ministry of Health day by day estimations of most extreme air temperature (Tmax) in summer months (June to August) were utilized to decide heatwave scenes as indicated by the definition prescribed by the IPCC. For all stations, total and dependable Tmax time arrangements were accessible for the period 2004–2018 concerning a few stations. We tried the 95th thresholds percentile. The extra wave impacts were assessed utilizing a one-stage model to guarantee that their belongings were evaluated subsequent to expelling the general impact of temperature.","PeriodicalId":7515,"journal":{"name":"Al-Mustansiriyah Journal of Sciences","volume":"1 1","pages":"15-23"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90591032","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}

Many algorithms have been developed for classification, such as Back Propagation (BP) neural networks, decision tree, Bayesian networks etc., and have been used repeatedly in many fields. These algorithms speak of the problem of imbalanced data, where there are situations that belong to more classes than others. Imbalanced data result in poor performance and bias to a class without other classes. In this paper, we proposed three techniques based on the Over-Sampling (O.S.) technique for processing imbalanced dataset and redistributing it and converting it into balanced dataset. These techniques are (Improved Synthetic Minority Over-Sampling Technique (Improved SMOTE), Borderline-SMOTE + Imbalanced Ratio(IR), Adaptive Synthetic Sampling (ADASYN) +IR) Algorithm, where the work these techniques are generate the synthetic samples for the minority class to achieve balance between minority and majority classes and then calculate the IR between classes of minority and majority. Experimental results show ImprovedSMOTE algorithm outperform the Borderline-SMOTE + IR and ADASYN + IR algorithms because it achieves a high balance between minority and majority classes.","PeriodicalId":7515,"journal":{"name":"Al-Mustansiriyah Journal of Sciences","volume":"13 1","pages":"25-29"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77698713","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 optimum ratio of ZnO-CNR was selected to be the tiny size of the ZnO nanorods that yielded a good stabilizer material and antibacterial activity. The ultraviolet-visible (UV-Vis) absorption spectrum of the ZnO-CNR nanocomposites appeared absorption peaks in the ultraviolet region at (350-360 nm) wavelength attributes with the energy gap of (3.41 eV) of ZnO-CNR.
