The title extended solid coordination compound, {[Fe(C(44)H(40)N(2)O(4)P(2))(C(3)H(7)NO)(2)](ClO(4))(2)·2C(3)H(7)NO}(n), was crystallized un-ex-pectedly from the reaction mixture containing the Trost ligand (1R,2R)-(+)-1,2-diamino-cyclo-hexane-N,N'-bis-(2'-di-phenyl-phosphinobenzo-yl) and Fe(ClO(4))(2)·6H(2)O in a 1:1 ratio in dimethyl-formamide (DMF) under reflux conditions. The polymeric comp...

Portable sensors and biomedical devices are influenced by the recent advances in microfluidics technologies, compact fabrication techniques, improved detection limits and enhanced analysis capabilities. This paper reports the development of an integrated ultraportable, low-cost, and modular digital microfluidic (DMF) system and its successful integration with a smartphone used as a high-level c...

Yöntem: İstanbul ilinde yaşayan beş ila on üç yaş arasında diş tedavisi için Marmara Üniversitesi Pedodonti kliniğine başvuran; 325 (167 erkek, 158 kız) çocuktan oluşan çalışma grubunda siyah dışsal re...

Dimethyl fumarate (DMF) is an effective treatment option for relapsing-remitting multiple sclerosis (MS), but its therapeutic mechanism of action has not been fully elucidated. A better understanding of its mechanism will allow for the development of assays to monitor its clinical efficacy and safety in patients, as well as guide the development of the next generation of therapies for MS. In or...

The synthesis of several phosphine Cu(I) complexes is reported, and their reactivity towards the solvents ethylenediamine (en) and dimethylformamide (dmf) has been investigated. CuX(PPh3) [X = Cl (1), Br (2)], CuCl(PCy3) (3) and CuCl(PPr3)n [n = 1 (4), 2 (5)] were prepared according to adapted literature procedures. The complexes CuCl(PPr3)n were obtained in crystalline form from a hexane solut...

Cationic and mixed-valent forms of Fe3O(CO2)6 trigonal prismatic clusters have been linked by ditopic links, namely, 1,4-benzenedicarboxylate (1,4-BDC) and 1,3-benzenedicarboxylate (1,3-BDC), to produce two 3-periodic metal-organic frameworks (MOFs), [Fe3O(1,4-BDC)3 (DMF)3][FeCl4] x (DMF)3 (MOF-235) and Fe3O(1,3-BDC)3 (py)3 x (py)0.5(H2O)1.5 (MOF-236) (DMF = N,N-dimethylformamide, py = pyridine...

The asymmetric unit of the title complex, [Co(DMF)(6)](ClO(4))(2) (DMF = N,N-dimethyl-formamide, C(3)H(7)NO), consists of two half complex cations with the Co(2+) metal ions located on centers of inversion and two perchlorate anions. In the crystal packing, each Co(2+) ion is coordinated by six mol-ecules of DMF in a slightly distorted octa-hedral geometry. The crystal structure is mainly stabi...

The structures of micelles of the surfactant polysorbate 80 (Tween 80) in 0-50% aqueous N,N-dimethylformamide (DMF) solutions (pH 7.2, ionic strength 2.44 mM) were investigated by means of small-angle X-ray scattering. At all the tested DMF concentrations, core-shell cylinder micelles formed; that is, increasing the concentration of DMF did not result in changes in the shape of the micelles. Th...

This paper presents a low-power structure of digital matched filters (DMFs), which is proposed for direct sequence spread spectrum systems. Traditionally, low-power approaches for DMFs are based on either the transposedform structure or the direct-form one. A new hybrid structure that employs the direct-form structure for local addition and the transposed-form structure for global addition is u...

We examine the completeness of death reporting in the Social Security Administration's Death Master File (DMF) through comparison with deaths by year and age group reported in official U.S. vital statistics. For most years since 1973, results suggest that the DMF includes 93 percent to 96 percent of deaths of individuals aged 65 or older. Although studies have shown that the National Center for...
