microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. in some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. maintaining higher biosorption capability and understanding the biosorption properties of dead cells are the keys to heavy metal removal and recov...

The anomalous dimensions of the gluon and ghost fields as well as those of the ghost-ghost-gluon and quark-quark-gluon vertexes are analytically computed at four loops in pQCD. Taken together with already available anomalous dimensions of the coupling constant, the quark field and the mass the results lead to complete knowledge of all renormalization constant entering into the renormalization o...

Problem Based Learning (PBL) and Cooperative Learning are both supported in a rich environment for active group learning. Groups of students are given a medical exploration environment to support learning by discovery and exploration. The environment implements a current approach to problem based learning (PBL) and extends it to support the joint reasoning and cooperation aspects in medical tea...

Recently rediscovered photographs of the remains thirteen individuals buried in Sado Valley Mesolithic shell middens Poças de S. Bento and Arapouco, excavated 1960 1962, show potential revisiting excavation archives with new methods. The analysis, which applies principles archaeothanatology is enriched by experimental taphonomic research, confirmed details concerning treatment dead body provide...

Empty mollusk shells may act as colonization surfaces for sclerobionts depending on the physical, chemical, and biological attributes of the shells. However, the main factors that can affect the establishment of an organism on hard substrates and the colonization patterns on modern and time-averaged shells remain unclear. Using experimental and field approaches, we compared sclerobiont (i.e., b...

A minute limpet-shaped shell, Qingjianglepas elegans n. gen. sp., is reported from the 518 million-year-old Qingjiang biota in Hubei, China. The new shell exhibits a typical limpet morphology with sculpture of strongly developed radial ribs, an anterior fold, and distinctive shape shift. Feature combinations such as are unique among Cambrian mollusk assemblages, but strikingly resemble that som...

Marine sediment records from the north Icelandic shelf, which rely on tephrochronological age models, reveal an average ΔR (regional deviation from the modeled global surface ocean reservoir age) of approximately 150 yr for the last millennium. These tephra-based age models have not hitherto been independently verified. Here, we provide data that corroborate ΔR values derived from these sedimen...

Curls and curves of a shell interweave its various strain modes and link them together. This interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. Such a test fails to work for shell elements and must be reconstructed. In this paper, it is tried to study shell interactional behavior a...

In the architecture of the mosque, the light entering into the dome is a functional necessity and due to the structure, the weight of the dome and its one or more shells has caused limitations in any kind of skylights to be encumbered. The research main question is that due to the mechanism of the dome parts, how the creation and the entering of skylights to the dome were done. The research met...

Topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine CSR2, CSR4 and CSR2XCSR4 crossbreed races of the silkworm, Bombyx mori L. The results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoo...
