BACKGROUND Carbohydrate Deficient Transferrin (CDT) is a new alcohol biomarker recently approved by the Food and Drug Administration for alcohol screening. Limited information is available on the economic benefits of alcohol biomarkers. Our objective was to conduct a cost-benefit analysis (CBA) of the CDT test in a primary care sample of patients being treated for diabetes and hypertension. M...

Many multimedia communication applications require a source to transmit messages to multiple destinations subject to quality of service (QoS) delay constraint. To support delay constrained multicast communications, computer networks need to guarantee an upper bound end-to-end delay from the source node to each of the destination nodes. This is known as multicast delay problem. On the other hand...

abstract export of nonoil goods in economic activities is so important and its effect on economic and comparative growth is undeniable. so, emphasize on agricultural sector and development of export in this sector prepares good conditions, for iran, to be present at international markets relying its advantages. the study tries to recognize necessary policies to enhance agricultural export poten...

The controversies surrounding intellectual property protection are most obvious when it comes to protecting indigenous knowledge. The firmly entrenched patenting laws in the developed world provide recognition and economic monopoly to individual inventors. Consequently, large and small companies have been able to appropriate the economic benefits from the technological knowledge protected throu...

A factorial experiment begun in 1980 included ‘Hamlin’ and ‘Valencia’ sweet-orange scions [Citrus sinensis (L.) Osb.], and Milam lemon (C. jambhiri Lush) and Rusk citrange [C. sinensis x Poncirus trifoliata (L.) Raf.] rootstocks, tree topping heights of 3.7 and 5.5 m, between-row spacings of 4.5 and 6.0 m, and in-row spacings of 2.5 and 4.5 m. The spacing combinations provided tree densities of...

Managers are typically interested in using equations that provide accurate volumes for large, merchantable trees while modelers are often more interested in equations that meet statistical assumptions. Therefore, modelers often use weighted (WLS) rather than ordinary least squares (OLS) to fit individual tree volume equations since the random error variance is not constant. Since OLS and WLS pr...

ecological changes resulting from climate conditions can severely affect human societies especially in the area of economy and safety. climate catastrophes may cause social and economic tension. forecasting such changes accurately can help the government to control the disasters and to achieve possible benefits (such as water supply in flood). weather forecasting is the application of science a...
