The field of rapid prototyping has been evolving at a fast pace since stereolithography, one of the first new solid freeform fabrication technologies, got introduced. Although, commercially available at the market for less than 8 years, it seems those new technologies are on the way to succeed all other existing prototyping technologies such as computer-numerically-controlled machinery, in many...

Biomass production systems include multiple-crops rotations, various machinery systems, diversified operational practices and several dispersed fields located in a range of distances between the various facilities (e.g., storage and processing facilities). These factors diversify the energy and cost requirements of the system. To that effect, assessment tools dedicated a single-crop production ...

a cross-sectional study to determine whether occupational exposure to antineoplastic drugs can cause hematologic changes was performed. blood samples were collected from a group of 24 hematology/oncology nurses who were exposed to antineoplastic drugs during a mean preiod of 5.5 years (standard error =1.1). the control group, matched by sex, and age, consisted of 18 nurses, worked on other sect...

This research was conducted at Food Micro, Small and Medium Enterprises (MSMEs) in Medan City. In this study, observations were made on all activities, so that the process stages risks affect halal each stage of are known. Furthermore, risk factors identified, House Risk (HOR) method is used to find dominant cause through calculation Aggregate Potential (ARP). The results showed there 9 process...

This paper describes a new formalization of Lexical-Functional Grammar called R-LFG (where the “R” stands for “Resource-based”). The formal details of R-LFG are presented in Johnson (1997); the present work concentrates on motivating R-LFG and explaining to linguists how it differs from the “classical” LFG framework presented in Kaplan and Bresnan (1982). This work is largely a reaction to the ...
