In the monomeric and centrosymmetric title Ni(II) complex, [Ni(C(7)H(4)ClO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center. The asymmetric unit contains one 2-chloro-benzoate ligand, one diethyl-nicotinamide (DENA) ligand and one coordinating water mol-ecule, the ligands being monodentate. The four O atoms in the equatorial plane around the Ni(II) ion for...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Hepatocarcinogenesis was induced in Sprague Dawley rats by injecting diethylnitrosamine (DENA); 150 mg/kg body weight, ip, a well known liver carcinogen and a mutagenic agent. Concurrent with the induction of hepatocarcinoma, psychological stress was also elicited from the changes in brain neurotransmitters. Noradrenaline and dopamine, the neurotransmitters of sympathetic system were estimated ...

In the title centrosymmetric mononuclear Ni(II) compound, [Ni(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the central Ni(II) atom is coordinated by two O atoms from two 4-formyl-benzoate (FOB) ligands, two O atoms from two water mol-ecules and two N atoms from two diethyl-nicotinamide (DENA) ligands. The coordination geometry is slightly distorted octa-hedral, with four O atoms in the equa...

Landslides along road corridors in Alaska national parks pose threats to public safety, visitor access, subsistence activities, and result costly remediation of damaged infrastructure. Landslide risk these areas, which contain near-surface permafrost, is associated with mean annual air temperatures (MAATs) above freezing heavy precipitation events. Historical (1981–2020) values MAAT summer (JJA...

This study analyzed the expression of negation markers in Buginese. The employed a descriptive qualitative method. data for this are some snippets daily speech Buginese Sinjai Dialect setting which we have verified as native speakers. results indicated that there two main ways expressing marker dena' can be used interchangeably with enna'. Negation dena'/enna' is if predicate verbal, adjectival...

dena biosphere reserve located in iran and is a 550 biosphere reserve in the worlds. this research was investigated in the two protected and non-protected areas, in a dena biosphere reserve, kohkeloye va boyrahmad province, and central zagros forest, southwest of iran. inventory methods designed by systemetic-randomaiz method by use the rectangular plots that were 15×30 meters in the 100×100 m ...

Following the Russian invasion of Ukraine this February, a global community volunteers has endeavored to help preserve Ukraine’s online cultural heritage. While comprises over 1300 volunteers, many them work as librarians or in preservation, including two leaders group, Quinn Dombrowski and Anna Kijas. Kijas, along with Sebastian Majstorovic, have been instrumental coordinating experts across t...
