extended abstract 1. introduction from about the 1950s, extraordinary growth of cities and increase of urban population have led to excessive growth of settlements in cities (muhallab taha, 2001(. this growth caused an unprecedented rise in land prices (zaheri & pour- mohammadi, 2006). land is an essential element in urban expansion and development (vander molen, 2002). therefore, quality and q...

In recent years we have witnessed the arrival of the technology necessary for building 3-dimensional electronic systems 1]. These systems could consist of a number of 2-dimensional electronic boards, stacked on top of each other. A large number of vertical interconnections, distributed over the surface of the boards, interconnect adjacent electronic planes. The primary alleged advantage of such...

Dendrochronological analysis was carried out for 13 historic icons from the collection of the Museum of the Folk Building in Sanok, painted on fir and spruce boards. Eleven sequences of the annual growth rings produced from the analysed fir boards were absolutely dated against the fir dendrochronological standard for S Poland, constructed by E. Szychowska-Krąpiec. Most of the analysed objects d...

Studies on vegetation changes of rangelands under grazed and non-grazedconditions are of great importance in the range management planning programs. To determinethe change process of vegetation, this study was performed in Inche Shorezar site of Golestanprovince for nine years (1997-2005). The vegetation parameters were measured every year inseveral fixed plots inside and adjacent of exclosures...

In the title compound, C(8)H(17)ClF(2)N(3)O(2)P, the phosphoryl group and the NH unit of the C(O)NHP(O) moiety adopt a syn conformation with respect to each other. The P atom is in a tetra-hedral coordination environment and the environment of the N atom of the C(O)NHP(O) moiety is essentially planar. In the crystal, adjacent mol-ecules are linked via N-H⋯O =P and N-H⋯O =C hydrogen bonds, build...

The retinal pigment epithelium (RPE) is a single cell layer adjacent to the rod and cone photoreceptors that plays key roles in retinal physiology and the biochemistry of vision. RPE cells were isolated from normal adult human donor eyes, subcellular fractions were prepared, and proteins were fractionated by electrophoresis. Following in-gel proteolysis, proteins were identified by peptide sequ...

Trophic survival mechanisms are crucial for the determination of cell numbers in the developing vertebrate nervous system, but important neurotrophic factor families such as the neurotrophins have not yet been found in either Drosophila or C. elegans. Two independent studies on distinct glial populations in Drosophila have now shown that their survival is regulated by EGF family members secrete...

Microorganisms are vital to environmental health, yet their association with disease often overshadows these benefits. Building citizen-science activities around the positive role of microorganisms and an understanding of their ubiquity can begin to dispel misconceptions while simultaneously engaging the public in research. Here, we describe a citizen-science microbiology project geared toward ...

Majorana bound states have been proposed as building blocks for qubits on which certain operations can be performed in a topologically protected way using braiding. However, the set of these protected operations is not sufficient to realize universal quantum computing. We show that the electric field in a microwave cavity can induce Rabi oscillations between adjacent Majorana bound states. Thes...

The topic of this paper arose out of a consideration of Costas sequences, which are used in sonar and radar applications. These sequences have the de/ning property that all di!erences of elements the same distance apart, are di!erent. Several in/nite families of Costas sequences are known; but there are many existence questions for length ¿ 32. In this article, we restrict ourselves to sequence...
