Crested wheatgrass (Agropyron cristatum (L.) Gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. The main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of Iran as low-maintenance turfgrass. The experimental design was a randomized complete block design with 3 re...

Dimensional analysis is widely used in physics and engineering to contribute to modeling systems in which variables are measured in incompatible units. I used dimensional analysis to rank the airlines in overall quality based on US Department of Transportation data: on-time arrivals, denied boardings, mishandled baggage, and customer complaints. The results conflict with the well-known airline ...

an experiment was conducted to evaluate the effects of different levels of mineral and vitamin premix on performance and egg traits of laying hens from 37 to 49 weeks of age. two hundred and forty laying hens (hy-line w-36 strain) were randomly assigned to 5 dietary treatments of four replicates each with 12 hens per replicate). the levels of mineral and vitamin premixes in the experiment were ...

in this study, the relationships between human resource practices (hrps), firm performance (service quality), and the mediation effects of employees’ abilities were examined. to assess the relationships between variables, before evaluating the fitted structural model, the measurement model was defined to verify that the measurement variables used to reflect the unobserved constructs do so in a ...

this study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, ph value of gastrointestinal (gi) tract and small intestinal morphology of laying hens. the experiment was a completely randomized design with 160 laying hens strain (w-36) from 32 to 42 weeks of age, with five treatments, four replicates an...

In the ICT sector, product-software is an important factor for the quality of the products (e.g. cell phones). In this context, open source software enables firms to avoid quality competition as they can cooperate on quality without an explicit contract. The economics of open source (OS) versus closed source (CS) business models are analyzed in a general two-stage model that combines aspects of...
