Years of service in industrial plant operating environments can cause varying types and degrees concrete deterioration on reinforced hyperbolic shell natural draft cooling towers. Exposure to water potentially result material erosion corrosion embedded reinforcing steel associated delamination spalling over time. Such affect the integrity structure degree that repair programs are required relia...
Let M (n) k be the space of Siegel modular forms of degree n and even weight k. In this paper firstly a certain subspace Spez(M (2n) k ) the Spezialschar of M (2n) k is introduced. In the setting of the Siegel three-fold it is proven that this Spezialschar is the Maass Spezialschar. Secondly an embedding of M (2) k into a direct sum ⊕ ⌊ k 10 ⌋ ν=0 Sym 2 Mk+2ν is given. This leads to a basic cha...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
The full exploration of gene-environment interactions requires model organisms with well-characterized ecological interactions in their natural environment, manipulability in the laboratory and genomic tools. The waterflea Daphnia magna is an established ecological and toxicological model species, central to the food webs of freshwater lentic habitats and sentinel for water quality. Its tractab...
We have produced draft whole-genome sequences for two bacterial strains reported to produce the bulgecins as well as NRPS-derived monobactam β-lactam antibiotics. We propose classification of ATCC 31363 as Paraburkholderia acidophila. We further reaffirm that ATCC 31433 (Burkholderia ubonensis subsp. mesacidophila) is a taxonomically distinct producer of bulgecins with notable gene regions shar...
In order to develop the land fund and help state be more proactive inallocating land, Ministry of Natural Resources Environment has proposed ChapterVIII on development in Draft amended Law Land. Within scope ofthis article, focus is analyzing evaluating limitations inadequacies theregulations based a comparison between amendedLaw Land current Land, thereby making some suggestions improvelegal p...
Due to yield increase, some farmers in Iran plant sugarbeet in 50-cm row spacing instead of conventional 60-cm row spacing. Low row spacings force farmers to harvest three consecutive rows instead of two alternate rows. This would increase the amount of draft requirement to pull the lifter through the soil. In order to use common medium tractors for pulling the three-unit sugarbeet lifter and p...
Abstract Laborers and draft animals played underexamined roles in building operating the waterworks of Mughal gardens landscapes. This article analyzes four sources evidence about water-related work: paintings; historical texts on political economy waterworks; assessed relation to modern estimates human animal energy needed build operate considered work natural waters shaping land society mater...
