In this work, the impact of variables; age sex cancer type, and frailty on patient survival has been estimated using Cox proportional hazards model. Fitting the model to the cancer data obtained from Ahmadu Bello University Teaching Hospital (ABUTH) Zaria, Cancer Registry Center, the results indicate that the covariates studied are relevant prognostic factors to patients’ survival. Also, presence of frailty has impact on the estimates. Female patients were found to be slightly more prone to failure than the male patients.

In this study a flood plain extension has been developed in ArcGIS and HE-CRAS models and a comparison has been made within three different scenarios of discharge. The results showed in low and medium discharge scenarios the buffer zone acts as a safety factor zone to adjacent infrastructure either agricultural or residential, but in high discharge condition buffer zone is entirely filled with stream water hence yet more safety regulation should be considered in order to avoid human and resource loss or damage within adjacent areas.

This solid waste further undergoes the process of decomposition producing several by-products such as odorous gases and volatile organic compounds. Both of these compounds have potential to severely damage physical and mental health of human. These components were analysed using AERMOD by United States Environmental Protection Agency (USEPA). AERMOD needs uniform and horizontally consistent surface and upper air parameters of meteorology. Along with AERMOD, Landfill Gas Emission Model (LandGEM Version 3.02) was used to form an emission inventory. LandGEM analyses odorous gases and VOCs. The dispersion of odorous gases over areas adjacent to landfill of Pune, India has been estimated from information on advances in emission inventory and field monitoring operation. Four odorous gases namely Total Landfill gas, Methane, Carbon Dioxide and Non Methane Organic Compounds (NMOC) were detected at 17 discrete places and were found within permissible limits.","PeriodicalId":89778,"journal":{"name":"International journal of biomaterials research and engineering","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83545371","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}

Calculations were carried out using the Finite Difference Time Domain (FDTD) Method. The results indicate that the SAR distribution does not much depend on the shape and size but it depends mainly on the electrical properties of the tissues. There is a drop in the magnitude of the SAR in the brain when moving from a cubical model to the spherical model. There is a magnitude drop in the eye, when going from a spherical model to the cubical model. For both brain and eye, when the size is decreased, the volume is reduced and therefore the electromagnetic energy absorption goes up. The human eye at 2500 MHz was considered to observe how the electrical properties of the tissues affect the electromagnetic energy absorption in an organ. When relative permittivity is perturbed in small percentages with conductivity remaining unchanged; the value of the maximum SAR also changes by small values. However, both these cases, when the electrical properties are changed, the location of maximum SAR remains unchanged. It is exactly at the center of the eye.","PeriodicalId":89778,"journal":{"name":"International journal of biomaterials research and engineering","volume":"102 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89747896","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}
