description: A cosmological theory that predicts a late-time accelerated attractor with a constant dark matter to dark energy ratio can be said to solve the Coincidence Problem. Such cosmologies are naturally generated in the context of non-standard gravity theories under conformal transformation because of the resulting couplings between scalar fields and matter. The present work examines four classes of these transformed theories and finds that only a small subset--those with a single scalar field--are capable of solving the Coincidence Problem.

description: Given an anisotropic fluid source, we determine in closed forms, upon solving the field equations of general relativity (GR) and teleparallel gravity (TEGR) coupled to a cosmological constant, cylindrically symmetric four-dimensional cosmological rotating wormholes, satisfying all local energy conditions, and cosmological rotating solutions with two axes of symmetry at finite proper distance. These solutions have the property that their angular velocity is proportional to the cosmological constant.

description: New zinc(II) Schiff base complexes (Z1 and Z2) were prepared through the treatment of ONNO tetradentate Schiff base ligands (H2L1 and H2L2) with zinc acetylacetonate. Elemental analysis (C, H and N) and other spectroscopic techniques such as FT-IR and 1H NMR were used to characterize the produced ligands and their associated Zn(II) complexes. The structure of Z1 was explored by single crystal X-ray diffraction analysis. The structural investigations of Z1 demonstrate that it exists in the form of a centrosymmetric dimer in which penta coordinated Zn(II) ions are inter connected via µ-phenoxo bridges from one of the phenolic oxygen atoms of each tetradentate Schiff base ligand to the opposite zinc(II) ions. The theoretical calculations, performed by DFT using the B3LYP/Def2-TZVP level of theory, directed that the intended outcomes are in compliance with the actual consequences. The nature and types of non-covalent interactions present among the sample molecules were also investigated by using QTAIM and NCI calculations. Furthermore, antimicrobial activities of the synthesized Schiff base ligands and their respective zinc(II) complexes were also examined against two Gram-positive (Staphylococcus aureus and Bacillus cereus) and two Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria, and two fungal species (Aspergillus brasiliensis and Candida albicans). The agar well diffusion method and poisoned media technique were used for the study of biological properties of bacterial and fungi species, respectively. According to assessments of inhibitory zones, metal chelates are found to be somewhat more efficient than free ligands.

description: There are broadly three channels to probe axion-like particles (ALPs) produced in the laboratory: through their subsequent decay to Standard Model (SM) particles, their scattering with SM particles, or their subsequent conversion to photons. Decay and scattering are the most commonly explored channels in beam-dump type experiments, while conversion has typically been utilized by light-shining-through-wall (LSW) experiments. A new class of experiments, dubbed PASSAT (Particle Accelerator helioScopes for Slim Axion-like-particle deTection), has been proposed to make use of the ALP-to-photon conversion in a novel way: ALPs, after being produced in a beam-dump setup, turn into photons in a magnetic field placed near the source. It has been shown that such hybrid beam-dump-helioscope experiments can probe regions of parameter space that have not been investigated by other laboratory-based experiments, hence providing complementary information; in particular, they probe a fundamentally different region than decay or LSW experiments. We propose the implementation of PASSAT in future neutrino experiments, taking a DUNE-like experiment as an example. We demonstrate that the magnetic field in the planned DUNE multi-purpose detector is already capable of probing the ALP-photon coupling down to $g_{aγγ} \sim {\rm few}\times 10^{-5}$ GeV$^{-1}$ for ALP masses $m_a \lesssim 10$ eV. The implementation of a CAST or BabyIAXO-like magnet would improve the sensitivity down to $g_{aγγ} \sim 10^{-6}$ GeV$^{-1}$.

Understanding land and resources management planning processes in British Columbia : a qualitative approach
Creators: name: Mascarenhas, Michael
Publisher: name: University of British Columbia

description: The introduction of public participation into land and resource management planning processes in British Columbia is portentous in terms of its scope and involvement. This program, known as the Provincial Land Use Strategy, is based on the concept of consensus or shared decision-making. This planning approach has required a major commitment of time and use of resources, not only by the provincial government but also by the individuals involved in these processes. Yet, at the same time, it has been a tremendous challenge and struggle, and many questions still remain unanswered. This research seeks to explore and understand people's views in public participation and land and resource management planning processes through their own unique experiences and associations. It is hoped that this research can lead to a better understanding of the way these planning processes appear to these people, and through that insight, lead to improvements in practice. This research uses alternative dispute resolution theory, conflict resolution, and human dimensions research (HDR) frameworks as an analytical model. This study utilises a qualitative case study approach, in-depth interviewing, a rigorous approach to data collection and analysis, and appropriate verification procedures (Creswell 1998). Qualitative analysis of the data revealed three overarching themes reflecting important issues or concerns to participants: legitimacy, efficacy, and efficiency. These themes were identified as essential planning components that contribute to either the promotion or preclusion of these planning processes. The recognition of these themes and the factors that comprise them elucidates the complexities of the concerns and issues of participants regarding land and resource management planning processes in British Columbia. It provides a comprehensiveness not identified in other studies and highlights categories of concern that need to be probed and examined further. Finally these cntena presents an alternative measure to some of the traditional approaches used to evaluate similar public dispute processes.

description: We present a thermodynamically consistent mesoscopic model of protein adsorption at liquid-solid interfaces. First describing the equilibrium state under varying protein concentration of the solution and binding conditions, we predict a non-trivial (non- monotonic) dependence of the experimentally observable properties of the adsorbed layer (such as the surface density and surface coverage) on these parameters. We subsequently proceed to develop a dynamical model consistent with the equilibrium description, which qualitatively reproduces known experimental phenomena and offers a promising way of studying the exchange of the adsorbed proteins by the proteins of the solution.

description: Reaction-diffusion equations (RDEs) are often derived as continuum limits of lattice-based discrete models. Recently, a discrete model which allows the rates of movement, proliferation and death to depend upon whether the agents are isolated has been proposed, and this approach gives various RDEs where the diffusion term is convex and can become negative (Johnston et al., Sci. Rep. 7, 2017), i.e. forward-backward-forward diffusion. Numerical simulations suggest these RDEs support shock-fronted travelling waves when the reaction term includes an Allee effect. In this work we formalise these preliminary numerical observations by analysing the shock-fronted travelling waves through embedding the RDE into a larger class of higher order partial differential equations (PDEs). Subsequently, we use geometric singular perturbation theory to study this larger class of equations and prove the existence of these shock-fronted travelling waves. Most notable, we show that different embeddings yield shock-fronted travelling waves with different properties.

description: Three metal complexes, [Cu(L1)]2 (1), [Cu(L2)] (2) and [Ni(L2) (H2O)2]·1.5H2O (3), were synthesized using two different ligands (H2L1=N,N′-bis(2-hydroxy-3-methyl-benzylidene)-2-hydroxy-propane-1,3-diamine and H2L2=N,N′-bis(2-acetyl-indane-1,3-dione)-2-hydroxy-propane-1,3-diamine) and characterized by different spectroscopic methods. Complex 1 was studied by single-crystal X-ray diffraction analysis. In 1, each Cu(II) metal center has distorted square pyramidal structure. Complexes 2 and 3 have square planar and octahedral geometries, respectively. The interaction of calf-thymus DNA (CT-DNA) with H2L2 and the metal complexes (1–3) has been probed by UV–Vis absorption, photoluminescence, cyclic voltammetry and viscosity measurements.
title: How entrepreneurial orientation can leverage innovation project portfolio management
Creators: name: Kock, Alexander

Publisher: name: Wiley-Blackwell
Year: 2024

description: Innovation project portfolio management (IPPM) is a key task in R&D management because this decision‐making process determines which R&D projects should be undertaken and how R&D resources are allocated. Previous research has developed a good understanding of the role of IPPM in R&D strategy implementation and of successful IPPM practices. But the fundamental orientations that drive the strategy formation and implementation process have never been investigated in the context of IPPM, and it is unclear whether successful practices are equally valid for different strategic orientations. This study, therefore, investigates the moderating impact of a firm’s entrepreneurial orientation on the relationship between strategic portfolio management practices and portfolio success. An empirical analysis of 257 firms shows that both innovativeness and risk taking as entrepreneurial orientation’s dimensions positively moderate the relationship between managerial practices and performance. Specifically, we find that firms high in innovativeness profit more from stakeholder engagement compared to firms low in innovativeness. Firms high in risk‐taking profit more from a clearly formulated strategy. With increasing innovativeness and risk‐taking propensity, firms also profit more from business case monitoring and agility in portfolio steering. The results suggest that a firm’s entrepreneurial orientation can leverage the effect of IPPM practices. Vice versa, a lacking entrepreneurial orientation can render these practices ineffective. Strategic orientation and IPPM practices should, therefore, be aligned with each other to enable firms to better implement their strategy and generate competitive advantage.

description: A modified Chevron N-Layer computer program has the capability of calculating the "work" done by the total load on a given load group. Earlier analyses of AASHO Road Test sections and test vehicles had permitted the development of damage factor relationships. This paper presents seven, namely two-tire and four-tire single axles, tandems, triaxles, and four-axle, five-axle, and six-axle groups. The two-tire axle (front or steering axle) has the most severe damage relationship. The 80-kN (18-kip) four-tire single axle was used as the reference axle and was assigned a damage factor of 1.0 for a specific amount of "work". Other axle arrangements and total loads producing that amount of "Work" were 63.6 kN (14.3 kips) for the two-tire axle, 166.4 kN (37.4 kips) for eight-tire tandems, 250.2 kN (56.25 kips) for twelve-tired triaxles, 333.6 kN (75.0 kips) for a sixteen-tired four-axle group, 415.0 kN (93.3 kips) for a twenty-tired five-axle group, and 496.4 kN (111.6 kips) for a twenty-four-tired six-axle group.  Using the damage factors for the various axle groupings, one trip of a vehicle having a gross weight of 534 kN (120 kips) can produce up to approximately 17 times the damage of an 80-kN (18-kip) axleload, depending on the particular axle groupings involved. Equally as significant effects can be attributed to the distribution of loads on a given type of vehicle. For example, a 355.9-kN (80-kip) vehicle having 53.4 kN (12 kips) on the steering axle and 151.3 kN (34 kips) on each of two sets of tandem axles has an equivalent damage factor of 1.80 per trip. If the load distribution is changed to 40.0 kN (9 kips) on the steering axle and 157.9 kN (35.5 kips) on each of two sets of tandem axles, the total damage factor per trip is reduced to 1.76. Other configurations and various ranges of loads are presented, evaluated in terms of damage per trip, and discussed.

description: A Zn(II) complex with two nicotinamide (nia) ligands, two chloride ions, and two co-crystallized nicotinamide molecules, [ZnCl2(nia)2].2nia, was synthesized and characterized on the basis of elemental analysis, spectroscopic techniques (UV-vis, FT-IR, 1H and 13C NMR), conductivity measurements, DFT and single-crystal X-ray crystallography. The complex crystallized in orthorhombic crystal system with pccn space group and cell dimensions: a = 27.1852(2), b = 7.6705(4), c = 12.7502(8) Å and α = β = γ = 90°. Single-crystal structural analysis revealed the presence of a neutral complex having tetrahedral geometry. In this complex, Zn(II) is coordinated to two chloride and two nicotinamide ligands in the coordination sphere and two nicotinamide molecules are co-crystallized. Hydrogen bonding interactions (N-H…O, C-H…O, N-H…N, C-H…Cl) along with π…π bonding interactions (between the coordinated nicotinamide and free nicotinamide moiety) stabilize the crystal lattice. The DFT studies consolidated the experimental findings and provided deeper insight into vibrational spectra, excitation spectra and hydrogen bonding interactions between nicotinamide molecules. The interactions and binding parameters of this complex with bovine serum albumin (BSA) have been probed through absorption and fluorescence spectroscopy which revealed the presence of static quenching mechanism and good binding propensity of the Zn complex.

description: We present a comprehensive study of the reversal process of perpendicular magnetization in thin layers of the ferromagnetic semiconductor Ga1-xMnxAs. For this investigation we have purposely chosen Ga1-xMnxAs with a low Mn concentration (x ~ 0.02), since in such specimens contributions of cubic and uniaxial anisotropy parameters are comparable, allowing us to identify the role of both types of anisotropy in the magnetic reversal process. As a first step we have systematically mapped out the angular dependence of ferromagnetic resonance in thin Ga1-xMnxAs layers, which is a highly effective tool for obtaining the magnetic anisotropy parameters of the material. The process of perpendicular magnetization reversal was then studied by magneto-transport (i.e., Hall effect and planar Hall effect measurements). These measurements enable us to observe coherent spin rotation and non-coherent spin switching between the (100) and (010) planes. A model is proposed to explain the observed multi-step spin switching. The agreement of the model with experiment indicates that it can be reliably used for determining magnetic anisotropy parameters from magneto-transport data. An interesting characteristic of perpendicular magnetization reversal in Ga1-xMnxAs with low x is the appearance of a double hysteresis loops in the magnetization data. This double-loop behavior can be understood by generalizing the proposed model to include the processes of domain nucleation and expansion.

description: A titanium(IV) Schiff base complex, [Ti(L)2]·H2O, was synthesized by treating TiO(acac)2 with an ONO-donor Schiff base ligand (H2L) derived from the condensation of 4-aminobenzohydrazide and 3-methoxysalicylaldehyde. The synthesized ligand and its respective complex were characterized by various spectroscopic techniques like FT-IR, 1H NMR, 13C NMR and elemental analysis (CHN). A single-crystal X-ray diffraction (SC-XRD) analysis was also accomplished to ensure the molecular structure of the complex. The geometry around the central metal ion in [Ti(L)2]·H2O was distorted octahedral as revealed by the data collected from diffraction studies. Hirshfeld surface analysis showed that H…H interatomic contact is the most significant contributor to the crystal packing of the complex. Moreover, theoretical calculations of the Schiff base complex were carried out by DFT at the B3LYP/Def2-TZVP level of theory, which showed a good correlation with the experimental findings.

description: Stellar halos in early-type galaxies (ETGs) are shaped by their accretion and merger histories. We use a sample of 1114 ETGs in the TNG100 simulation with stellar masses $10^{10.3}\leq M_{*}/M_\odot\leq 10^{12}$, selected at z=0 within the range of g-r colour and lambda-ellipticity diagram populated by observed ETGs. We study how the rotational support and intrinsic shapes of the stellar halos depend on the fraction of accreted stars, overall and separately by major, minor, and mini mergers. Accretion histories in TNG100 ETGs as well as the radial distributions of ex-situ stars $f_{ex}(R)$ strongly correlate with stellar mass. Low-mass ETGs have characteristic peaked rotation profiles and near-oblate shapes with rounder halos that are completely driven by the in-situ stars. At high $f_{ex}$ major mergers decrease the in-situ peak in rotation velocity, flatten the $V_{*}/σ_{*}(R)$ profiles, and increase the triaxiality of the stellar halos. Kinematic transition radii do not trace the transition between in-situ and ex-situ dominated regions, but for systems with $M_{*}>10^{10.6}M_\odot$ the local rotational support decreases with the local ex-situ fraction $f_{ex}(R)$ and triaxiality increases with $f_{ex}$. These correlations are followed by fast and slow rotators alike with a continuous and overlapping sequence of properties. Merger events dynamically couple stars and dark matter: in high mass ETGs and at large radii where $f_{ex}\gtrsim0.5$, both components tend to have similar intrinsic shapes and rotational support, and nearly aligned principal axes and spin directions. Based on these results we suggest that extended photometry and kinematics of massive ETGs ($M_{*}>10^{10.6}M_\odot$) can be used to estimate the local fraction of ex-situ stars and to approximate the intrinsic shapes and rotational support of the co-spatial dark matter component.

description: Cracking of portland cement concrete pavements is a common, even expected, occurrence. To minimize potentially detrimental effects, it is necessary to understand mechanisms that might be used to explain such behavior so that measures may be developed and implemented to control the occurrence of such cracking. Several "theories" are discussed that might provide the mechanisms of pavement cracking. An alternate meachanism, based on fatigue loading of the concrete by temperature expansions-contrations, for the development of so-called D-cracking is offered.

description: We classify the constraints on a stationary point of the potential invariant under a finite group into intrinsic and extrinsic based on whether they are independent of the coefficients in the potential or not. We find that the symmetry group of a set of stationary points can be larger than that of the potential and the stabilizer under this group generates intrinsic constraints. By applying these findings in the framework of the auxiliary group, we show that the constraints that can only be obtained extrinsically in an elementary theory can be generated intrinsically in an effective theory.

description: We investigate magnetic properties of lightly doped antiferromagnetic Mott insulators in the presence of non-magnetic impurities. Within the framework of the t-J model we calculate the doping dependence of the antiferromagnetic order parameter using the self-consistent diagrammatic techniques. We show that in the presence of non-magnetic impurities the antiferromagnetic order is more robust against hole doping in comparison with the impurity-free host, implying that magnetic order can re-appear upon Zn doping into lightly hole-doped cuprates. We argue that this is primarily due to the loss of coherence and reduced mobility of the hole quasiparticles caused by impurity scattering. These results are consistent with experimental data on Zn-doped LaSrCuO.

description: We study holographic aspects of mixed state entanglement measures in various large $N$ top-down as well as bottom-up confining models. For the top-down models, we consider wrapped $D3$ and $D4$ branes gravity solutions whereas, for the bottom-up confining model, the Einstein-Maxwell-dilaton gravity solution is considered. We study entanglement entropy, mutual information, entanglement wedge cross-section and entanglement negativity for the strip subsystems and find model independent features of these entanglement measures in all confining theories. The entanglement negativity and entropy exhibit a phase transition at the same critical strip length $L_{crit}$, at which the order of these measures changes from $\mathcal{O}(N^2)$ to $\mathcal{O}(N^0)$. The entanglement wedge cross-section similarly shows an order change at $L_{crit}$ and exhibits a discontinuous behaviour each time a phase transition between different entangling surfaces occur. We further test the inequality involving mutual information and entanglement wedge cross-section, and find that the latter always exceeds half of the former.

description: Burning of rice stubbles is widely practised in Punjab, India, due to a lack of suitable machinery to direct drill wheat into combine-harvested rice residues. Although burning is a rapid and cheap option, and allows quick turn around between crops, it has serious effects on human and animal health due to air pollution, reduced soil fertility due to loss of nutrients and organic matter, and green house gas (GHG) emissions. The recently developed Happy Seeder (HS) overcomes the technical problems associated with direct drilling into rice residues. The primary aim of the present study was to conduct a preliminary evaluation of the direct financial benefits and costs to farmers of use of the HS in comparison with the current practices of straw burning followed by direct drilling or conventional tillage prior to sowing. The results of the evaluation suggest that the HS technology is more profitable than conventional cultivation or direct drilling after burning, and that it is viable for farmers from a financial perspective. The net present value (NPV) of the benefits is highly sensitive to yield; a 5% increase in yield with the HS doubles the increase in NPV of the HS over conventional tillage. The NPV is also quite sensitive to changes in herbicide use, and less sensitive to changes in irrigation water saving and discount rate. Furthermore, there are significant economic, community and environmental benefits through adoption of the technology. For widespread adoption of the technology, a range of potential mechanical, technical, social, institutional and policy constraints need to be considered and addressed in conjunction with a detailed economic assessment of the HS technology.

description: When the term highway pavement is used, most people think of the moderate to thick systems on which their vehicles travel on intermediate- or high-type roadways. These pavement systems are typically constructed of bituminous concrete or portland cement concrete. This is not to say that low-volume roads do not have a pavement system; however, in case of low-volume roads, the pavement system usually consists of unbound aggregates, sod, soil materials, or at the most very thin or moderate applications of a binding material. It is the high-type pavement systems to which the comments in this paper will be addressed specifically.  These high-type pavements serve two primary functions. On the one hand, these pavements are the wearing surface upon which the tires of the vehicles travel. Because of high stresses at the tire-pavement interface, the surfacing materials must be extremely stable. The hard, bound surface provides a dust-free and smooth-riding surface. Secondly, the pavement system provides a means of transferring the total load of the vehicle to the supporting subgrade or earth foundation. The design of such a pavement system is thus a structural problem very similar to the design of bridges or office buildings.

description: We present the current status of ongoing searches for molecular hydrogen in high-redshift (1.8 < zabs <= 4.2) Damped Lyman-alpha systems (DLAs) capitalising on observations performed with the ESO Very Large Telescope (VLT) Ultraviolet and Visual Echelle Spectrograph (UVES). We identify 77 DLAs/strong sub-DLAs, with log N(HI) >= 20 and z_abs > 1.8, which have data that include redshifted H2 Lyman and/or Werner-band absorption lines. This sample of HI, H2 and metal line measurements, performed in an homogeneous manner, is more than twice as large as our previous sample (Ledoux et al. 2003) and considers every system in which searches for H2 could be completed so far, including all non-detections. H2 is detected in thirteen of the systems with molecular fractions of values between f=5x10^-7 and f=0.1, where f=2N(H2)/(2N(H2)+N(HI)). Upper limits are measured for the remaining 64 systems with detection limits of typically log N(H2)=14.3, corresponding to log f=-1.3 (i.e., 1/20th solar), with X = Zn, S or Si, have molecular fractions log f>-4.5, while H2 is detected -- regardless of the molecular fraction -- in 50% of them. In contrast, only about 4% of the [X/H]-4.5. We show that the presence of H2 does not strongly depend on the total neutral hydrogen column density, although the probability of finding log f>-4.5 is higher for log N(HI)>=20.8 than below this limit (19% and 7% respectively). The overall H2 detection rate in log N(HI)>=20 DLAs is found to be about 16% (10% considering only log f>-4.5 detections) after correction for a slight bias towards large N(HI). [truncated]

Measuring Retail Food Price Variation: Does the Data Source Matter?

description: The main area of focus in this paper is variation across regions and over time in the U.S. as estimated by different food price data sets. There are a variety of potential sources for food price data, but it is important to compare the relative strengths and weaknesses of the data sources in order to estimate the magnitude of the variation in average prices from the different sources. No one data source can account for all potential measurement problems, but by estimating average food prices for similar, or even identical products, one can test for whether there are significant differences in average food prices based on the data source.

description: Simple Malthusian models remain an important tool for understanding pre-modern demographic systems and their connection to the economy. But most recent literature has lost sight of the institutional context for demographic behavior that lay at the heart of Malthus’s own analysis. This paper estimates a short-run version of a Malthusian model for two Württemberg communities from 1646 to 1870. Württemberg differed institutionally from the northwest European societies analyzed in previous studies. The impact of institutional differences shows clearly in differing demographic reactions to economic shocks. Mortality was less sensitive to shocks than one would expect, while nuptiality was especially sensitive.

description: This paper reports on a case study to establish dollar values for loss of biodiversity in the New Zealand coastal marine environment. The study uses the European Shore Crab (Carcinas maenas) as the example alien invasive species and the Pauatahanui Inlet, Wellington, New Zealand, as the ecosystem representative of the coastal marine environment. Choice modelling is the stated preference tool used to elicit marginal dollar values for these various attributes of the inlet. Reallocation of existing government expenditure is used as the payment mechanism. Results indicate a wide range of dollar values for the marginal losses to the environment, with no clear trend on a distance-decay relationship. The probability distributions of the dollar values of the environmental attributes tended to have a concentration around the median with very wide tails, especially on the high side. This indicates that most people generally agreed on a dollar value, but a very few individuals expressed extremely high values. The study concludes that the dollar values for loss of biodiversity and other environmental attributes do provide useful information to decision makers, but considerable caution needs to be exercised when applying these values in benefit cost studies. Marginal rate of substitution estimates between environmental attributes will be useful for estimating money values for attributes identified given future work estimates a statistically significant money value for one.
The Harder They Fall, the Bigger They Become: Tidal Trapping of Strings by Microstate Geometries

description: We consider the fate of a massless (or ultra-relativistic massive) string probe propagating down the BTZ-like throat of a microstate geometry in the D1-D5 system. Far down the throat, the probe encounters large tidal forces that stretch and excite the string. The excitations are limited by the very short transit time through the region of large tidal force, leading to a controlled approximation to tidal stretching. We show that the amount of stretching is proportional to the incident energy, and that it robs the probe of the kinetic energy it would need to travel back up the throat. As a consequence, the probe is effectively trapped far down the throat and, through repeated return passes, scrambles into the ensemble of nearby microstates. We propose that this tidal trapping may lead to weak gravitational echoes.

description: The ep -> e'pi^+n reaction was studied in the first and second nucleon resonance regions in the 0.25 GeV^2 < Q^2 < 0.65 GeV^2 range using the CLAS detector at Thomas Jefferson National Accelerator Facility. For the first time the absolute cross sections were measured covering nearly the full angular range in the hadronic center-of-mass frame. The structure functions sigma_TL, sigma_TT and the linear combination sigma_T+epsilon*sigma_L were extracted by fitting the phi-dependence of the measured cross sections, and were compared to the MAID and Sato-Lee models.

description: 2-Methylimidazolium pyridine-2,5-dicarboxylato zinc(II) dihydrate crystal (1) is synthesized and characterized by Fourier transform infrared spectroscopy (FTIR), single crystal X-ray diffraction analysis (SCXRD), thermogravimetric-differential thermal analysis (TG-DTA), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), powder X-ray diffraction analysis (PXRD), proton nuclear magnetic resonance (1H NMR) studies, electronic absorption studies (UV-VIS) and DNA interaction studies. 1 was then explored for anti-microbial, anti-oxidant and anti-cancer activity. The SCXRD studies show that the compound crystallizes in the triclinic system and exhibits a distorted octahedral geometry with methyl imidazole ion as the cation. An exothermic decomposition at 400 °C implies high temperature stability in TG-DTA. PXRD confirms the phase purity of the sample. 1H NMR and UV-VIS results show that the solution structure of 1 is in agreement with SCXRD data. DNA interactions evaluated by agarose gel electrophoresis method substantiate the intercalative mode of binding. Anti-oxidant analysis shows that it exhibits good scavenging ability against DPPH and NO radicals. Anti-microbial activity suggests that 1 has better activity against Escherichia coli than Staphylococcus aureus. Further, the potential anti-cancer activities of complex indicate that the compound has good activity with a half-maximal inhibition concentration (IC50) value of 21.3 against MCF-7 human breast cancer cell line, suggesting that it may act as an anti-breast cancer drug.

description: Making conservation program payments conditional on outcomes offers potential efficiency and innovation improvements over input based contracts. This paper explores the trade-offs involved in choosing the payment criteria for biodiversity tenders. A model where the budget for a conservation tender can be allocated to input, outcome or mixed payments is used to explore the impacts of hidden actions, adverse selection, and landholder risk aversion on the optimal policy design. We discuss the implications of these results for the design of the ‘Nest Egg’ tender. This tender is targeting habitat and breeding of ground-nesting birds in the New South Wales Murray Catchment.
