Assessment of occupational noise exposure of a plant in oil industry
Dal, Ufuk; Birlik, Gülin; Department of Engineering Sciences (2010)
Noise, which is a noteworthy problem in the world of workers, influences the health, safety, productivity and efficiency of those working in heavy industries and especially those working in petroleum industry. The objective of this study is to reassess the protective measures, taken previously by the company, from the point of view of the negative effects of noise on the workers. For this purpose, two approaches are adopted. Firstly, through questionnaires (response rate: 86%) distributed to workers, their ...
Assessment of health risks associated with the consumption of wastewater-irrigated vegetables in urban areas
Jabeen, F.; Manzoor, M.; Ibrahim, M.; Mahmood, A.; Adrees, M.; Aslam, A.; Kanwal, U.; Vithanage, M.; Yousaf, Balal (2022-08-01)
Several health issues are related to toxic metals among which Pb, Cr, Cd, and Ni are categorized as human carcinogenic. We analyzed the health risks linked with food chain contamination due to vegetables irrigated with wastewater containing metals. Thirty-six samples of each vegetable, water, and soil (at two depths, 0-15 cm, and 15-30 cm) were collected individually from 12 different locations near Paharang drain, Faisalabad, and the contamination level of each metal (Cd, Cr, Mn, Ni, and Pb) was determined...
Assessment of carbon dioxide transmission through porous building materials in relation to indoor air quality
Yüncü, Başak; Tavukçuoğlu, Ayşe; Saltık, Emine Nevin; Department of Building Science in Architecture (2016)
There is lack of knowledge on breathing features adequacy of porous building materials for sustaining indoor air quality. There is necessity to examine gas diffusion characteristics of breathing porous building materials and the relation of those characteristics with IAQ. A comprehensive study, therefore, was conducted on mud brick as a traditional building material and AAC as a contemporary building material which are well-known by their high breathable characteristics. Their air permeability features were...
Assessment of liquefaction susceptibility of fine grained soils
Pehlivan, Menzer; Çetin, Kemal Önder; Department of Civil Engineering (2009)
Recent ground failure case histories after 1994 Northridge, 1999 Kocaeli and 1999 Chi-Chi earthquakes revealed that low-plasticity silt-clay mixtures generate significant cyclic pore pressures and can exhibit a strain-softening response, which may cause significant damage to overlying structural systems. These observations accelerated research studies on liquefaction susceptibility of fine-grained soils. Alternative approaches to Chinese Criteria were proposed by several researchers (Seed et al. 2003, Bray ...
Assessment of fuel quality parameters of sewage sludge samples from different treatment schemes
Atak, Onur; Atimtay, Aysel; Sanin, Faika Dilek (2018-05-01)
The fuel quality of dried sewage sludge samples was investigated to assess their potential use as auxiliary fuel in combustion processes. Dewatered sewage sludge samples were taken from six wastewater treatment plants in Turkey using different wastewater and sludge treatment processes. The fuel quality of the dried sludge was examined from the calorific point of view. The effects of wastewater and sludge treatment processes on calorific value, carbon and volatile matter content were determined. Dried sewage...
