Abstract:

Systematic sampling is one of the simplest and popular methods for selecting a random sample from a finite population. The diagonal systematic sampling scheme is a type of systematic sampling design which has gained the attention of researchers during the last two decades. In this paper, a modification to the conventional diagonal systematic sampling design is proposed for use in situations where population units follow a linear trend. It is found that the proposed strategy reduces the variance of the diagonal systematic sampling thus resulting in an efficient sampling design. The mathematical conditions under which the suggested modified diagonal systematic sampling design is more precise than some of the available sampling designs are derived. With the help of a numerical illustration using milk yield data, it is shown that the proposed sampling scheme is more efficient than some of the available sampling schemes.

Abstract:

SUMMARY: Widely used probability-proportional-to-size (PPS) selection methods are not well adapted to circumstances requiring sample augmentation. Limitations include: (1) an inability to augment selections while maintaining PPS properties, (2) a failure to recognize changes in census stratum membership which result from sample augmentation, and (3) imprecise control over line item sample size. This paper presents a new method of PPS selection, a modified version of sieve sampling which overcomes these limitations. Simulations indicate the new method effectively maintains sampling stratum PPS properties in single- and multi-stage samples, appropriately recognizes changes in census stratum membership which result from sample augmentation, and provides precise control over line item sample sizes. In single-stage applications the method provides reliable control of sampling risk over varied tainting levels and error bunching patterns. Tightness and efficiency measures are comparable to randomized systematic sampling and superior to sieve sampling.

<em>Abstract.</em>—A systematic, standardized approach to monitor fish assemblages has been applied in Ohio’s rivers since 1979. A primary objective is the assessment of changes in response to water pollution abatement and other water quality management programs. All major, nonwadeable rivers were intensively sampled using standardized electrofishing methods and a summer–early fall index period. Most rivers were sampled two or three times, before and after implementation of pollution controls at major point source discharges and best management practices for nonpoint sources. A modified and calibrated index of biotic integrity (IBI) was used to demonstrate and evaluate changes at multiple sampling locations in major river segments. An area of degradation value (ADV) and an area of attainment value (AAV) were also calculated from IBI results to demonstrate the magnitude and extent of changes in fish assemblage condition along segments and between sampling years. Positive responses in the IBI and the ADV/AAV were observed 4 to 5 years after implementing improved municipal wastewater treatment. Positive responses were much less apparent in rivers predominantly influenced by complex industrial sources, agricultural nonpoint sources, and extensive hydrologic modifications. The ADV/AAV showed incremental improvements in river fish assemblages, unlike pass/fail IBI thresholds, and tiered IBI biocriteria provided more appropriate benchmarks than chemical, physical, or qualitative biological criteria. The results show the value of standardized and intensive fish assemblage monitoring and the use of tools that reveal the extent and severity of impairments to determine the effectiveness of water pollution control programs.

Abstract:

Abstract Recent developments in sampling and analytical techniques have enabled scientists to identify and track compositional changes in the molecular weights of paraffin hydrocarbons in organics rich shales wells towards higher molecular weight paraffin hydrocarbons. High molecular weight carbon chains (HMWCs) are generally regarded as the problematic hydrocarbons as they have the highest tendency to precipitate, deposit, and restrict flow in near wellbore zones, flowlines, valves, and chocks. This paper presents a systematic laboratory approach for monitoring and screening for of C60+paraffin waxes in shale oils and field deposits. A comprehensive validation methodology for benchmarking polymeric chemistries in laboratory for controlling and inhibiting C61 – C100 paraffin waxes is discussed based on the results from gas chromatography analysis (GC), differential scanning calorimetry analysis (DCS), X-ray diffraction analysis (XRD), and cold finger wax deposit testing. Modes of action of four polymeric chemistries are discussed based on laboratory data. Results showed none of the polymeric compounds performed as wax crystal modifiers for C60+paraffins, but more likely did disperse C60+wax crystals to some degree. This leads to the alarming conclusion that use of some paraffin inhibitors could lead to a much severe wax deposition when higher amounts of very large paraffin molecules are present in reservoir hydrocarbons. A plausible theory is proposed based on the "folded chain model" and common understanding of how polymeric inhibitors interact with paraffin wax molecules. It was found that model oil systems are more realistic for suitable to screening existing and new inhibitor chemistries for wax control and management when very high molecular weight paraffin molecules are present.
