A case study on acoustic performance and construction costs of noise barriers

In the study, the barriers used for reducing traffic noise are being examined in means of performance and construction cost. First a noise prediction is made in the sample highway under certain traffic conditions in order to determine the noise barrier requirement and the results are confirmed by measurement. According to the noise prediction equations used in Turkey, Germany and Canada, the effects of heavy vehicle...

A prediction model for the level of well water

There is a nonlinear relationship between rainfall and well water levels. This is one of the most complicated hydrologic phenomena to understand due to the existence of spatial and temporal incoherent geomorphic and climatic factors. The aim of this study is to predict the well water level by the artificial neural networks. A well is located on the campus area of Izmir Institute of Technology, Izmir, Turkey. While...

Preliminary studies on phytochemicals and larvicidal effects of Acacia nilotica L. extracts against Anopheles arabiensis Patton

Acacia nilotica is a natural forest tree with many traditional uses in Sudan. Preliminary laboratory studies were conducted to analyze the phytochemical constituents of three extracts (water, ethanol and petroleum ether) prepared from A. nilotica (leaves and fruits), and to evaluate their larvicidal effects against the malaria vector mosquito,Anopheles arabiensis. The knockdown and residual effects of the...

Measuring risk and designing risk management strategies for dry onion growing farms: A case study for Amasya Province of Turkey

The aim of this study was to measure the risks and to design appropriate risk management strategies for dry onion growing farms in Amasya Province of Turkey. The data used in the study belong to the 2007-2008 production period and were obtained through questionnaires from 101 farms, selected by stratified sampling method. Operational and financial risks exposed by farms were measured using probability distribution...
