plant density affects yield components and seed yield by influencing the changing vegetative growth and environmental resources. these effecting factors were studied in the spring of 2006 at ramin agricultural research and natural resources university, mollasani in northeast of ahwaz, using a randomized complete block design of a factorial layout with 4 replications. main factors were planting ...
We report that planar chiral structures affect the polarization state of light in a manner similar to three-dimensional chiral (optical active) media. In experiments with artificial metal-on-silicon chiral planar gratings of 442 wallpaper group symmetry, containing millions of chiral elements per square centimeter, we observed rotation of the polarization azimuth in excess of 30 degrees of ligh...
Self-signaling models predict less selfish behavior in a probabilistic giving setting as individuals are expected to invest pro-social identity. However, there is also substantial evidence that people tend exploit situational excuses for choices (for instance, uncertainty) and behave more selfishly. We contrast these two motivations (identity management self-deception) experimentally order test...
BACKGROUND Mandibular resections are routinely carried out for achieving a R0 resection for oral cancers. However, the need of mandibular resection to achieve this has always been questioned. The present study was carried out to define the pattern of mandibular involvement in carcinoma of the mandibular region. PATIENTS AND METHODS A total of 25 consecutive patients who had undergone mandibul...
Fungi metabolise organic matter in situ and so alter both the bio-/physico-chemical properties and microbial community structure of the ecosystem. In particular, they are responsible reportedly for specific stages of decomposition. Therefore, this study aimed to extend previous bacteria-based forensic ecogenomics research by investigating soil fungal community and cadaver decomposition interact...
abstract narcissus species (amaryllidaceae) are highly suitable outdoor ornamental plants and also as cut flower. narcissus is used in folk medicine and is a medicinal plant, because of galanthamine properties. south area of iran such as khouzestan province, is one of the most important areas of producing cut flower of narcissus in winter season. in this research, the effects of planting distan...
Optimal bucking methods were applied to two operational sites of the Nasu-machi Forest Owners’ Co-operative to maximize profits, with and without taking log size into consideration, and to maximize revenues considering a new subsidy system and higher unit prices of smallsized logs. Corresponding optimum extraction rates and small-sized log prices were examined. Extraction rates from stands usin...
