Land use changes of the Balcova-Guzelbahce shore line investigated using geographical information system (GIS) and remote sensing technique

  This study investigated and determined land use changes resulting from economic pressure to develop the land which means development pressures, more specifically anthropogenic stresses, originate urbanization on agricultural land such as dam, swamp, highway, settlement and recreation area. The study, based on aerial photographs and satellite images, geographical information system (GIS) and remote sensing...

Ergonomical evaluation of manually operated weeder under wet land condition

  Drudgery involved in weeding operation increases stress on the worker causing increase in heart rate and oxygen consumption. Ergonomic evaluation of weeding operations by different age group of workers at different working hours showed that the heart rates corresponding to cono- weeder and Mandava weeder were 154.54 beats/min and 140.17 beats/min, respectively. Oxygen consumption rate was 1.76...

Non linear analysis of a functionally graded beam with variable thickness

  The nonlinear analysis of a functionally graded beam under combined loads is investigated analytically in this paper. The point loads and moment is applied at the end of the beam. The area section is considered to vary continuously along the longitudinal axis of the beam. The most important idea for presentation of this paper is the application of the present method for a vast class of functionally graded and...

A new conditional invariant detection framework (CIDF)

  Software engineering included some different process such as designing, implementing and modifying of software. All these processes are done to have fast developed software as well as reach a high quality, efficient and maintainable software. Invariants help programmer and tester to do most steps of software engineering more easily. Invariants are mostly always true but of course with a specific confidence....

Endogenous ethanol production in the larva of oil palm weevil (Rhynchophorus palmarum, coleoptera; curculionidae)

  This study investigated the larva of oil palm weevil for the presence of endogenous ethanol. The body tissue fluid of the larva was made and its alcoholic content determined using the specific gravity method. The alcohol content as percentage by volume was estimated from the laboratory alcoholometry. For comparison, the alcohol contents of lager beer and red wine were also estimated. Results showed that the...
