Abstract:
Abstract The Soleris Non-fermenting Total Viable Count method was previously validated for a wide variety of food products, including cocoa powder. A matrix extension study was conducted to validate themethod for use with cocoa butter and cocoa liquor. Test samples included naturally contaminated cocoa liquor and cocoa butter inoculated with natural microbial flora derived from cocoa liquor. A probability of detection statistical model was used to compare Soleris results at multiple test thresholds (dilutions) with aerobic plate counts determined using the AOAC Official Method966.23 dilution plating method. Results of the two methods were not statistically different at any dilution level in any of thethree trials conducted. The Soleris method offersthe advantage of results within 24 h, compared tothe 48 h required by standard dilution plating methods.

Abstract:
ABSTRACT This paper investigates the potential of using a frequency response mode to reduce the dilution effect of non-diagnostic evidence on auditors' fraud risk judgments. In two experiments, we test one hypothesis and examine a research question related to the dilution effect where response mode (frequency versus probability) and type of non-diagnostic or irrelevant information are manipulated between-participants. Results of the hypothesis tests show that auditors' fraud risk judgments demonstrate a significantly lower dilution effect when they evaluate diagnostic and non-diagnostic or irrelevant evidence using a frequency response mode, as compared to the probability response mode; this effect is most pronounced when auditors are provided with favorable non-diagnostic or irrelevant evidence.

Abstract:
Operational dilution in open-pit mining can influence short-term mine planning and affect the adherence between designed and executed plans, impacting the reconciliation results. This type of dilution may occur due to several reasons, such as erroneous assumptions regarding contacts, inefficient mining performance, and uncertainties associated with the planned grades. The use of uncertainties enables better predictability and achievement of planned targets. Using the mine planning polygons and grade models, a methodology is proposed to measure the dilution ranges in each region. The methodology considers the uncertainty associated with the ore grades to verify the probability of occurrence of dilution in the short-term mine plan. The results demonstrated that the use of uncertainties enabled identification of the areas with a higher potential of incurring operational dilution. Using this information, the plans can be adjusted to minimize dilution, or the result can be used as a factor to correct the planned data.

Abstract:
Abstract Studies on the propagation of medicinal and ornamental plant species show of great relevance as they contribute to the domestication, cultivation and production of these species. However, there are not enough information concerning the interaction of the different plant growth regulators and the recommended dilution vehicles. This work aimed to evaluate the effects of sodium hydroxide (NaOH) and ethanol as rooting inducers, as well as their performance as vehicles for diluting indolebutyric acid (IBA) and naphthalene acetic acid (NAA) in stem cuttings of the species Varronia curassavica and Melaleuca alternifolia. Stem cuttings of both species were submitted to the treatments: control with distilled water, hydroethanolic solution (50% v v-1), NaOH solution in distilled water, indolebutyric acid diluted in hydroethanolic solution, indolebutyric acid diluted in NaOH solution, naphthalene acetic acid diluted in hydroethanolic acid and naphthalene acetic acid diluted in NaOH solution (0.5 N). The design used was completely randomized, with the averages compared by the Scott-Knott test at 5% probability. Better rooting of the cuttings was observed when IBA was applied using both dilution vehicles. For M. alternifolia, percentages of average survival of 26.43% were verified. Rooting was more satisfactory when using NaOH as a dilution vehicle for both IBA (16.66%) and NAA (23.33%). For V. curassavica, IBA (2000 mg L-1) is the most suitable plant regulator, diluted in both hydroethanolic solution and in NaOH, while for M. alternifolia, NaOH is recommended as a dilution vehicle for plant growth regulators NAA (500 mg L-1) and IBA (500 mg L-1). When applied isolated, the dilution vehicles do not stimulate and do not harm the rooting of the two species.

Abstract:
Abstract A study was conducted to determine the efficacy of the Soleris Non-fermenting-Total Viable Count (NF-TVC) automated growth-based method for semiquantitative detection of mesophilic, aerobic microorganisms in a variety of food products. A probability of detection (POD) statistical model was used to compare Soleris results at multiple test thresholds (dilutions) with aerobic plate counts determined using reference dilution plating procedures. Nine naturally contaminated food products were tested, with Soleris testing performed at three or four threshold levels for each food. Using the POD model, all Soleris test results were in statistical agreement with the reference plating procedures with the exception of a single threshold level in two trials with black pepper, and a single threshold level in the independent laboratory trial with cheesecake. Results of ruggedness testing showed that the Soleris method produced accurate results even when minor variances in operating parameters, including sample volume and incubation temperature, were introduced. Results of the internal and independent laboratory validation studies showed that the Soleris NF-TVC method can be used as an accurate alternative to conventional dilution plating procedures for evaluation of microbial counts at threshold levels, while saving 24 h or more in analysis time.

Abstract:
Dilution and transport predictions for an ocean outfall proposed for the Barra da Tijuca, Rio de Janeiro are summarized. The initial characteristics of the wastefield are predicted using the results of recent experiments on submerged wastefield characteristics in stratified flows. Using measured currents and stratifications, it is predicted that the proposed design will result in a wastefield which is always submerged, whose thickness varies from 8.5 to 23.1 m and whose dilution varies from about 200 to well over 2000. The wastefield will often stay near the ocean bottom. Far field transport due to currents is calculated and expressed in terms of spatial “visitation frequency,” the probability of the wastefield visiting any location. It is shown that no effluent reaches shore with a travel time less than 5.5 hours, and computations including oceanic diffusion and bacterial mortality suggest maximum shoreline coliform concentrations of 500 per 100 mℓ, and 98% of the time they will be less than this. For reasons discussed these estimates of shoreline bacteria are conservatively high, and much lower than computed by methods assuming steady onshore currents.

Abstract:
Background: Homeopathy is highly controversial. The main reason for this is its use of very highly dilute medicines (high homeopathic potencies, HHP), diluted beyond the Avogadro/Loschmidt limit. Research using Nano Tracking Analysis has demonstrated the presence of particles in HHPs. This study aims to verify the results of a previous publication that identified the ionic composition of these particles in all dilutions. Methods: We used Scanning Electron Microscopy & Energy Dispersive X-Ray Spectroscopy (SEM-EDX) to examine dilutions of a commonly used homeopathic medicine, an insoluble metal, Cuprum metallicum, for the presence of particles (NPs). The homeopathic medicines tested were specially prepared according to the European pharmacopoeia standards. We compared the homeopathic dilutions/dynamizations of copper with simple dilutions and dynamized lactose controls. Results: We observed an ionic diversity common to all preparations including HHPs but also significant differences in the relative quantity of each ion between manufacturing lines of homeopathic copper and lactose controls. The probability that the observed differences could have occurred chance alone (especially above Avogadro limit) can be rejected at p < 0.001. The essential component of these homeopathic medicines is sodium hydrogen carbonate, modulated by some other elements and by its quantity, size and shape. Conclusion: Homeopathic medicines made of Cuprum metallicum do contain material with a specific ionic composition even in HHPs diluted beyond the Avogadro/Loschmidt limit. This specificity can be attributed to the manufacturing process. This material demonstrates that the step-by-step process (dynamized or not) does not match the theoretical expectations of a dilution process. The starting material and dilution/dynamization method influences the nature of these NPs. Further measurements are needed on other raw materials using the same controls (solvent and simply diluted manufacturing lines) to support these findings. The role of sodium bicarbonate must be carefully studied in the future.

We report on the synthesis of Si1−x Ge x alloy nanocrystals by very-high-frequency plasma-enhanced chemical vapor deposition (VHF PECVD) technique at different silane to germane gas flow ratio (R) in a mixture of (H2+Ar) dilution gas and H2 dilution gas alone. TEM, SAED, EDS studies and HAADF-STEM mapping of the samples were done to investigate the NCs' size, crystallinity and distribution of Si and Ge in the Si1−x Ge x alloy NCs. The average estimated size of the NCs in all the samples are in the order of exciton Bohr radius of Ge (24.3 nm), thereby indicating the probability of good quantum confinement. The alloy nature of NCs was confirmed in Raman study. The content of Ge in SiGe NCs was evaluated from Raman spectra which show a direct correlation with the fraction of hydrogen flow in the dilution gas mixture.

Abstract:
SUMMARYThe twin concepts of zooprophylaxis and the dilution effect originated with vector-borne diseases (malaria), were driven forward by studies on Lyme borreliosis and have now developed into the mantra “biodiversity protects against disease”. The basic idea is that by diluting the assemblage of transmission-competent hosts with non-competent hosts, the probability of vectors feeding on transmission-competent hosts is reduced and so the abundance of infected vectors is lowered. The same principle has recently been applied to other infectious disease systems – tick-borne, insect-borne, indirectly transmitted via intermediate hosts, directly transmitted. It is claimed that the presence of extra species of various sorts, acting through a variety of distinct mechanisms, causes the prevalence of infectious agents to decrease. Examination of the theoretical and empirical evidence for this hypothesis reveals that it applies only in certain circumstances even amongst tick-borne diseases, and even less often if considering the correct metric – abundance rather than prevalence of infected vectors. Whether dilution or amplification occurs depends more on specific community composition than on biodiversityper se. We warn against raising a straw man, an untenable argument easily dismantled and dismissed. The intrinsic value of protecting biodiversity and ecosystem function outweighs this questionable utilitarian justification.

Several factors, such as interfering microbes, toxins, or disaggregation of adhering microbes, may distort the results of a serial dilution experiment. A mild enough distortion may not raise suspicion with a single outcome. The test introduced here judges whether the entire set of serial dilution outcomes appears unusual. This test forms lists of the possible outcomes. The set of outcomes is declared unusual if any occurrence of an observed outcome is on the first list, or more than one is on the first or second list, etc. A similar test can apply when there are only a finite number of possible outcomes, and each outcome has a calculable probability, and few outcomes have tied probabilities.

Abstract:
Selection of mutants in a microbial population depends on multiple cellular traits. In serial-dilution evolution experiments, three key traits are the lag time when transitioning from starvation to growth, the exponential growth rate, and the yield (number of cells per unit resource). Here, we investigate how these traits evolve in laboratory evolution experiments using a minimal model of population dynamics, where the only interaction between cells is competition for a single limiting resource. We find that the fixation probability of a beneficial mutation depends on a linear combination of its growth rate and lag time relative to its immediate ancestor, even under clonal interference. The relative selective pressure on growth rate and lag time is set by the dilution factor; a larger dilution factor favors the adaptation of growth rate over the adaptation of lag time. The model shows that yield, however, is under no direct selection. We also show how the adaptation speeds of growth and lag depend on experimental parameters and the underlying supply of mutations. Finally, we investigate the evolution of covariation between these traits across populations, which reveals that the population growth rate and lag time can evolve a nonzero correlation even if mutations have uncorrelated effects on the two traits. Altogether these results provide useful guidance to future experiments on microbial evolution.

Abstract:
This paper establishes a mathematical model of assessing the various factors of the uncertainty in analysis of nitrite in water by HPLC-DAD, investigates all the steps of the measurement by HPLC and calculates the various factors of evaluating the uncertainty analysis. The result shows: in this method the nitrite content in certain domestic sewage is measured 1.161 mg·L-1, and the uncertainty from the standard material and the test standard deviation under the repeatable conditions contribute mainly to the uncertainty of measuring the nitrite content in water. The uncertainty from the standard material generally includes the uncertainties from standard dilution, standard product purity and the environment temprature, in which the extraction, dilution and stability of the standard solution are the main contributors to the uncertainty from standard dilution. After calculation the relative uncertainty synthesis of nitrite content in water uncertainty is 0.0050, when the confidence probability P=95% and the expanded uncertainty 0.012mg·L-1. Without regard to the inhomogeneity of the nitrite distribution in water sample, the content of nitrite in water sample can be presented as (1.161±0.012) mg·L-1.
