The Effects of Cultural Values on Traditional Islamic-Arabic Houses in the Middle East
Culture and design determine the space-influenced values; they specifically outline space variations between values within a culture in relation to design space-influenced values. By the vision of an ideal life, one can shape and mold the vision of space by reflecting cultural forces such as religious beliefs. The purpose of this study will determine cultural values and religious beliefs and, in turn, assess the effects on the formation of houses in the Middle East. For this principle, the elements of traditional Islamic-Arabic homes showed effects by determining certain elements such as the bent entrance, the courtyard, the Haramlek and Salamlik (women’s and men’s quarters), and the Mashrabiya (wooden windows). Qualitative analysis was used as the method to analyze the case studies comparing traditional courtyard homes to today’s housing. The results have shown that today’s housing was unsuccessful when trying to imitate the provision of privacy as it was in the houses during the past.
Riyadh's vanishing courtyard houses
La decouverte de gisements petroliers en 1939 en Arabie Saoudite, leur exploitation et la croissance economique qui s'ensuivit eurent un fort impact sur les modes de vie, notamment sur l'architecture. Cet article a pour objet les styles architecturaux, alliant a la fois des lignes traditionnelles et occidentales, de la ville de Riyadh (region centrale du Najd).
LABORATORY AND FIELD TESTING OF SEED SPACING UNIFORMITY FOR SUGARBEET PLANTERS
Five planter configurations were evaluated for seed spacing uniformity at three field speeds using a seed 
location method in the field and a laboratory method involving an opto-electronic sensor system. Planter seed spacing 
uniformity was described using the Coefficient of Precision (CP3) measure. Results showed that CP3 measures 
determined using the laboratory test method were significantly different from those determined using the field test method. 
This indicated the laboratory test method cannot be used to predict planter seed spacing uniformity in the field. Seed 
spacing uniformity determined in laboratory tests was higher than, or equal to, seed spacing uniformity determined in 
field tests. This indicated the laboratory test method may be useful to screen out planters or planter units with poor 
uniformity of seed metering. Field testing of the planters that perform well in laboratory tests must be conducted to 
adequately determine the seed spacing uniformity of those planters in the field. Results from laboratory and field tests 
could be useful in determining areas for improvement of planters or planter units.
