TL;DR: Two copper-binding compounds/cofactors were isolated from the spent media of both the wild type and a constitutive soluble methane monooxygenase mutant, PP319, and high concentrations of CBCs were observed in the extracellular fraction of the sMMOC mutants PP319 and PP359 regardless of the copper concentration in the culture medium.
Abstract: Two copper-binding compounds/cofactors (CBCs) were isolated from the spent media of both the wild type and a constitutive soluble methane monooxygenase (sMMO C ) mutant, PP319 (P. A. Phelps et al., Appl. Environ. Microbiol. 58:3701–3708, 1992), of Methylosinus trichosporium OB3b. Both CBCs are small polypeptides with molecular masses of 1,218 and 779 Da for CBC-L 1 and CBC-L 2 , respectively. The amino acid sequence of CBC-L 1 is S?MYPGS?M, and that of CBC-L 2 is SPMP?S. Copper-free CBCs showed absorption maxima at 204, 275, 333, and 356 with shoulders at 222 and 400 nm. Copper-containing CBCs showed a broad absorption maximum at 245 nm. The low-temperature electron paramagnetic resonance (EPR) spectra of copper-containing CBC-L 1 showed the presence of a copper center with an EPR splitting constant between those of type 1 and type 2 copper centers (g ⊥ = 2.087, g ∥ = 2.42 G, ‖A ∥ ‖ = 128 G). The EPR spectrum of CBC-L 2 was more complex and showed two spectrally distinct copper centers. One signal can be attributed to a type 2 Cu 2+ center (g ⊥ = 2.073, g ∥ = 2.324 G, ‖A ∥ ‖ = 144 G) which could be saturated at higher powers, while the second shows a broad, nearly isotropic signal near g ⊥ = 2.063. In wild-type strains, the concentrations of CBCs in the spent media were highest in cells expressing the pMMO and stressed for copper. In contrast to wild-type strains, high concentrations of CBCs were observed in the extracellular fraction of the sMMO C mutants PP319 and PP359 regardless of the copper concentration in the culture medium.

TL;DR: It is found that labor pain relief medications diminish early suckling but are not associated with duration of breastfeeding through 6 weeks postpartum, and breastfeeding duration did not differ between unmedicated and medicated groups.
Abstract: We examined the relationship of labor pain relief medications with neonatal suckling and breastfeeding duration in 129 mothers delivering vaginally. Suckling was measured using the Infant Breastfeeding Assessment Tool (IBFAT). Controlling for infant age, birthweight, and gender, infants of unmedicated mothers had higher IBFAT suckling scores than those of medicated mothers (x = 11.1 vs. x = 8.2 respectively, P = .001). IBFAT suckling scores for intravenous and epidural groups were similar (x = 8.5) while those who received a combination of both intravenous and epidural medications were lower (x = 6.4 +/- 2.96, P = .001). Mothers evaluated their breastfeeding similarly to nurse evaluators (Z = 9.39, P = .001). Breastfeeding duration did not differ between unmedicated and medicated groups; however, dyads with low IBFAT scores weaned earlier than those with medium or high scores. Labor pain relief medications diminish early suckling but are not associated with duration of breastfeeding through 6 weeks postpartum.

TL;DR: In this article, a multiple objective formulation of the multi-product, multi-period aggregate production planning problem is presented, which provides individual consideration of the conflicting multiple objectives without resorting to a priori trade-off decisions through subjective cost estimation.
Abstract: This paper presents a multiple objective formulation of the multi-product, multi-period aggregate production planning problem. The proposed model provides for individual consideration of the conflicting multiple objectives without resorting to a priori trade-off decisions through subjective cost estimation. A numerical example is solved using three Multiple Objective Decision Making Methods.

TL;DR: In this paper, the authors demonstrate the importance of separating the bundled good of housing into land and improvements, arguing that changes in a property's overall value will depend critically on how much of its total value is contained in the land, a proportion we call land leverage.
Abstract: ∗∗∗ ∗∗∗ This article demonstrates the importance of separating the bundled good of housing into land and improvements, arguing that changes in a property’s overall value will depend critically on how much of its total value is contained in the land, a proportion we call land leverage. The importance of this deconstruction is demonstrated by highlighting how land leverage helps to explain variation in house price appreciation in Wichita, Kansas. Noting that land leverage should be relevant for many real estate issues and policies, we highlight four specific areas where consideration of land leverage could significantly improve our understanding of real estate markets. Land is the only thing in the world that amounts to anything ... for ‘tis the only thing in this world that lasts, and don’t you be forgetting it! ‘Tis the only thing worth working for, worth fighting for—worth dying for. Gerald O’Hara in Gone with the Wind 1 It has long been recognized that housing, despite its frequent treatment as single good in the press (e.g., the housing market, the housing bubble, etc.), is a bundled good. The academic literature has recognized the magnitude of the variation across dwellings, which has led to a general acceptance of “qualitycontrolled” price indexes over simple price indexes, such as those based on mean or median prices. At the same time, it is common to assume (often implicitly) that the prices of these heterogeneous attributes all appreciate at the same rate. In considering how the value of a home changes over time, however, it is important to recognize that the values of these bundled components do not necessarily

TL;DR: In this article, the effect of axial ligation on the photoinduced charge separation and charge recombination of a series of covalently linked porphyrin−C60 dyads is investigated.
Abstract: The effect of axial ligation on the photoinduced charge separation and charge recombination of a series of covalently linked porphyrin−C60 dyads is investigated Toward this, meso-tetraphenylporphyrin and its zinc(II) derivative are functionalized at the ortho or para positions of one of the aryl groups to bear a fulleropyrrolidine entity through a flexible ethylene dioxide bridge to probe the effect of intramolecular electron transfer phenomena In o-dichlorobenzene, 01 M (TBA)ClO4, the synthesized dyads exhibit seven one electron reversible redox reactions within in the potential window of the solvent and the measured redox potentials and UV−visible absorption spectra reveal charge−transfer interactions between the electron donor, porphyrin, and the electron acceptor, fullerene entities The geometric and electronic structures of the dyads probed by ab initio B3LYP/3-21G(*) methods also revealed the existence of charge−transfer interactions The excited state photochemical events are monitored by both
