In the title compound, [Mn(C(8)H(3)NO(6))(C(8)H(7)N(3))(2)(H(2)O)]·0.5H(2)O, the Mn(2+) ion is octa-hedrally coordinated by two 2-(1H-pyrazol-3-yl)pyridine ligands, one 4-nitro-phthalate ligand and one coordinated water mol-ecule leading to an overall MnN(4)O(2) coordination environment. The two 2-(1H-pyrazol-3-yl)pyridine ligands, which deviate from planarity by 0.0187 (2) and 0.0601 (2) Å, ma...

Problem statement: Digital transmission over band-limited communication channel largely suffers from ISIS and various noise sources. The presence of ISI and noise causes bit errors in the received signal. Equalization is necessary at the receiver to overcome these channel impairment to recover the original transmitted sequence. Traditionally equalization is considered as equivalent to inverse f...

The phase and orientation of manganese nitride grown on MgO~001! using molecular beam epitaxy are shown to be controllable by the manganese/nitrogen flux ratio as well as the substrate temperature. The most N-rich phase, u phase ~MnN!, is obtained at very low Mn/N flux ratio. At increased Mn/N flux ratio, the next most N-rich phase, the h phase ~Mn3N2!, is obtained having its c axis normal to t...

tehran is one of the most polluted metropolises in the world. sink capacity for absorption and assimilation of pollution is reduced generally due to failure in inclusion of ecological aspects in regional land use development planning. the present condition of air and water related issues in tehran are greatly affected by landscape structural alterations at urban level. in this research the focu...

If word strings violate grammatical rules, they elicit neurophysiological brain responses commonly attributed to a specifically human language processor or grammar module. However, an ungrammatical string of words is always also a very rare sequence of events and it is, therefore, not always evident whether specifically linguistic processes are at work when neurophysiological grammar indexes ar...

Investigation of the properties of MnxGa1-xN semiconductor alloy is performed on the basis of LCAO electron band structure of this semiconductor. The authors model this alloy on the basis of Mn substitutions on Ga sites and it is identified that the ternary semiconductor MnxGa1-xN has two tetrahedral binary constituents – GaN and MnN. It is found that the sp 3 hybrid orbital of the N atom attra...

Product-expiry date represent important information for products consumption. They must contain clear information in the label. The expiry date information stamped on the cover of product faced some challenges due to their writing in pencil and distorted characters. In this paper, an automated vision approach for recognizing expiry date numerals of industrial product is presented. The system co...

The incorporation of manganese into semiconducting ScN, using radio frequency molecular beam epitaxy, has been investigated. X-ray diffraction and reflection high energy electron diffraction measurements show the face-centered tetragonal rocksalt-type crystal structure with Sc and Mn cations and N anions. In addition to the solute incorporation into the lattice, which is clear from the position...

Digital images require large amounts of memory for storage. Thus, the transmission of an image from one computer to another can be very time consuming. By using data compression techniques, it is possible to remove some of the redundant information contained in images, requiring less storage space and less time to transmit. Artificial Neural networks can be used for the purpose of image compres...
