Anisotropic PP and PSv Prestack Depth Migration of 4C (OBC) Seismic Data, Offshore Trinidad

In November 2004, EOG Resources acquired an ocean-bottom cable (OBC) 4C swath survey across the Pamberi-1 well location in the Lower Reverse L block of the Columbus basin, eastern offshore Trinidad. The purpose of the 4C survey was to evaluate the potential of long-offset multicomponent technology for resolving lithology and stratigraphic detail in an area perturbed by shallow gas, overpressure and illumination shadows from normal regional faults and major anticlinal ridge trends acting as pressure seals. The motivation from EOG for attempting this was because a conventional 3D towed-streamer survey acquired the previous year failed to adequately image the target reflectors comprising the reservoir under the main growth fault.
Strategies for Retaining a Multigenerational Workforce

As organizations become more age diverse, some business leaders face challenges managing a multigenerational workforce. The purpose of this single case study was to explore strategies that leaders at a university in Northwest Florida implemented to retain their age-diverse workforce. The targeted population was higher education business managers who had success with retaining an age-diverse staff. The conceptual framework of the study was Herzberg’s 2-factor theory of motivation. A significant tenet of this theory is employees explain satisfying and dissatisfying experiences based on intrinsic and extrinsic factors related to their job functions. The data collection process included face-toface interviews with 4 participants and a review of company documents, including the university’s strategic plan and diversity and inclusion initiatives. Through coding and thematic analysis, 7 themes emerged that could help leaders retain a multigenerational workforce: foster a diversity-friendly workplace culture, implement effective interpersonal communication strategies, employ a formal approach, encourage a healthy work-life balance, value employees and their differences, offer professional growth opportunities, and eliminate negative generational stereotyping. Developing and cultivating retention strategies may contribute to social change by helping managers and leaders enrich retention rates, thereby increasing employment stability, improving productivity, and enhancing organizational and community relations.
VECTOR FINITE ELEMENT ANALYSIS OF MULTICOMPONENT INDUCTION RESPONSE IN ANISOTROPIC FORMATIONS

Abstract—Multicomponent induction logging responses are simulated by using hierarchical mixed order vector finite element method (FEM). In order to modeling three orthogonal magnetic dipoles, we adopt the method that the total field is separated into incident field and secondary field, and only the secondary field is computed by FEM. In addition, two techniques are applied to improve the modeling accuracy and computational efficiency: 1) Hierarchical mixed order vector basis functions are applied to FEM. Different order basis functions are used in different elements in accordance with the changing speed of the field. The mixed order scheme reduces greatly the number of unknowns without reducing accuracy, and can attain much higher computational efficiency. 2) The system of the FEM equations is solved by Distributed-SuperLU, and the results of multiple measure points can be got simultaneously. The FEM result is validated against volume integral equation method and the approach of planar layered media Green’s functions, and the comparisons show very good agreement. Finally, the multicomponent induction response in anisotropic formations involving eccentric tools and dipping beds is included to demonstrate the flexibility of the method.
Estimating Potential Output: a Survey of the Alternative Methods and their Applications to Brazil

This paper presents the main issues involved in estimating potential output. The objective is to describe the alternative methods and analyze their application and implications for growth forecasts and macroeconomic policy in Brazil. The text emphasizes the determinants of potential output under fixed and flexible coefficients of production. Given the wide use of aggregate measures of total factor productivity in growth accounting, and the sensitivity of such a variable to economic assumptions and errors of measurement, the text also presents the main applied critiques and alternatives to aggregate growth-accounting exercises. The main conclusions are: (1) the annual potential growth rate of Brazil’s GDP varies substantially depending on the method and hypotheses adopted and, what is most important, potential GDP is not separable from effective GDP in the long-run; (2) growth-accounting and time-series studies of Brazil result in low potential-output growth rates because they extrapolate the slow growth of 1981-2003 to the future; (3) capital seems to be the main constraint on growth in Brazil and, therefore, a demand-led increase in investment can raise both its effective and potential output levels; (4) however, because of the slow adjustment of the capital stock, an investment boom can also hit a supply constraint before the stock of capital has time to adjust to the growth rate of investment; and (5) aggregate measures of potential output do not carry much information about the economy and, therefore, they should be complemented by sectoral estimates of capacity utilization to identify the bottlenecks in inter-industry flows and the corresponding demand pressures on inflation.
Interactions between different biological forms of aquatic macrophytes in a eutrophic tropical reservoir in Northeastern Brazil

The aquatic plants and biological processes have different interactions and their knowledge may contribute to the understanding of environmental dynamics in wetlands. The aim of this study was to report the type of interactions that different biological forms of macrophytes stand in the eutrophic tropical reservoir of Penha reservoir, Northeastern Brazil. Data collection was captured every two months from October 2009 to October 2010, considering the hydrological cycle in one-year period. For this, twelve perpendicular transects (separated by 10 m) at the reservoir’s water edge were defined; each transect had two plots of 625 cm² (25 x 25 cm, separated by one meter) from which samples were obtained. Plants were collected and transported in identified plastic bags for subsequent quantification of the dry weight biomass; additionally, pressed samples were made in the field for identification purposes. The relative interaction index (RII) was used to identify the existence of positive and/or negative interactions between the biomass of the biological forms of aquatic plants. Student’s t-tests were used to analyze variations in the abiotic data and biomass over time, and to determine differences between the dry and rainy seasons. Pearson and Spearman correlation coefficients were calculated to determine correlations between the biological forms and the biomass of the macrophytes, as well as environmental variables and RII. In the dry season, the environment was mainly composed of floating macrophytes (1 013.98 g/m²), with mats of submerged macrophytes (98.18 g/m²) that demonstrated a range of positive (RII= 1.0) to negative (RII= -0.2) interactions. The biomass of emergent macrophytes increased throughout the dry season (4.87 to 106.91 g/m²) due to the nurse plant effect that served as a substratum (RII= 1.0). During the rainy season the biomass of submerged macrophytes was reduced by 97 % due to direct and indirect relationships (RII= -1.0) to other macrophytes. Rainfall and emergent plants contributed to a reduction in the biomass of floating macrophytes (19.16 g/m²). The emergence of a third group of plants (emergent) lead floating plants to occupy other areas and excluded submerged plants. Overall, the interactions among plants within ecosystems were not definite due to stand composition and seasonality.
Relation between Hypercholesterolemia and Insulin like growth factor-1 in Elderly Women suffer from Hypothyroidism

The present study included 40 female subjects. They were classified into two groups: group I included 20 females diagnosed as primary hypothyroidism with age ranged between 45 – 65 years and group II included 20 ages matched normal female volunteers and served as control group. Insulin like growth factor -1, (IGF-1) cholesterol, triglycerides, Thyroid stimulating hormone, thyroxine-3 (T 3 ) and thyroxine-4 (T 4 ) hormones were measured in both groups. The obtained results revealed that, there was a significant decrease in IGF-1 level in group I, when compared to control group (P ? 0.01). Correlation studies showed that IGF-1 is strongly positively correlated with T 3 (R=0.81, P ? 0.01) and moderately positively correlated with T 4 (R= 0.58, P ? 0.05). Meanwhile, it was moderately negatively correlated with cholesterol (R= 0.6, P ? 0.05). The results indicate that IGF-1 deficiency in elder women suffering from ? hypothyroidism may have a direct relation in the pathogenesis of hypercholesterolemia. Keywords : Hypercholesterolemia: Insulin like growth factor -1: Elderly: Hypothyroidism: growth hormone: thyroid hormone: cholesterol.
PROPERTY TAX COLLECTOR PERFORMANCE AND PAY

The few empirical studies on the relationship between performance and pay in the public sector have been unable to measure adequately public sector output This paper overcomes this measurement problem by focusing on the pay of the local property tax collector, for whom an output indicator—the property tax collection rate—can be objectively quantified. The empirical results suggest that higher levels of performance cause an increased amount of pay, ceteris pahbus. No evidence is found, however, linking higher pay to increased performance.
Investigation of Vacancy Defects on the Young's Modulus of Carbon Nanotube Reinforced Composites in Axial Direction via a Multiscale Modeling Approach

In this article, the influence of various vacancy defects on the Young’s modulus of carbon nanotube (CNT) - reinforcement polymer composite in the axial direction is investigated via a structural model in ANSYS software. Their high strength can be affected by the presence of defects in the nanotubes used as reinforcements in practical nanocomposites. Molecular structural mechanics (MSM)/finite element (FE) Multiscale modeling of carbon nanotube/polymer composites with linear elastic polymer matrix is used to study the effect of CNT vacancy defects on the mechanical properties. The nanotube is modeled at the atomistic scale using MSM, where as the interface we assumed to be bonded by Vander Waals interactions based on the LennarJonze potential at the interface and polymer matrix. A nonlinear spring is used for modeling of interactions. It is studied for zigzag and armchair Nanotubes with various aspect ratios (Length/Diameter). Finally, results of the present structural model show good agreement between our model and the experimental work.
The role of self-esteem in Internet addiction: a comparison between Turkish, Polish and Ukrainian samples

Background and Objectives: Internet use, which has become extremely important and essential in everyday life, often leads to problematic use. The main aim of our study was to answer the question of whether self-esteem is a predictor of Internet addiction. Methods: The participants were 1,011 people from three countries: Turkey (N = 320), Poland (N = 350), and Ukraine (N = 341). Young's Internet Addiction Test and Rosenberg's Self-Esteem Scale were used. Results: Results provide evidence that self-esteem is a predictor of Internet addiction and that this pattern is found across cultures. Conclusions: People who approach themselves with heavy self-criticism and evaluate themselves as unworthy are more prone to Internet addiction. More research is also needed to provide a better understanding of the Internet addiction phenomenon and its relation to self-esteem, personality, and culture.

TILLAGE TIME AFFECTS SOIL HYDRO-THERMAL PROPERTIES, SEEDLING GROWTH AND YIELD OF MAIZE (ZEA MAYS L.)

Two-year experiments were conducted to determine optimum tillage time to improve soil compaction and hydro-thermal properties for maize growth. Two tillage treatments: no-tillage (NT), and subsoiling (SS) were performed in correspondence to eight tillage times from March 25 to July 20 (I: March 25, II: April 10, III: April 25, IV: May 10, V: May 25, VI: June 10, VII: July 5, and VIII: July 20) at 15 days interval, synchronously with eight sowing times. SS significantly decreased soil bulk density (0-30 cm) by about 0.13 g cm -3 at times of I–V, and about 0.08 g cm -3 at VI–VIII. Increment in total soil porosity due to SS was about 3.88% during I–V and about 2.27% at VI–VIII. SS significantly increased soil moisture content by 1.60% in 10-30 cm soil profile. Soil minimum temperature significantly increased by about 0.58 °C (0-20 cm) for I–V, while an increase of 1.06 °C (0-10 cm) was seen for maximum soil temperature due to SS. Greater seedling dry matter coupled with higher growth, and yield improvement was achieved with SS. Dry matter accumulation and grain yield was maximum for May 25 to June 10 sowing as compared to early (22%, 43.5%) and late (60%, 41%, respectively) sowing due to SS versus NT. Initial SS intervals could alleviate soil compaction and low temperature stress for spring maize, with improved soil hydrothermal properties.
Former Food Products Safety Evaluation: Computer Vision as an Innovative Approach for the Packaging Remnants Detection

Former food products (FFPs) represent a way by which leftovers from the food industry (e.g., biscuits, bread, breakfast cereals, chocolate bars, pasta, savoury snacks, and sweets) are converted into ingredients for the feed industry, thereby keeping food losses in the food chain. FFPs represent an alternative source of nutrients for animal feeding. However, beyond their nutritional value, the use of FFPs in animal feeding implies also safety issues, such as those related to the presence of packaging remnants. These contaminants might reside in FFP during food processing (e.g., collection, unpacking, mixing, grinding, and drying). Nowadays, artificial senses are widely used for the detection of foreign material in food and all of them involve computer vision. Computer vision technique provides detailed pixel-based characterizations of colours spectrum of food products, suitable for quality evaluation. The application of computer vision for a rapid qualitative screening of FFP’s safety features, in particular for the detection of packaging remnants, has been recently tested. This paper presents the basic principles, the advantages, and disadvantages of the computer vision method with an evaluation of its potential in the detection of packaging remnants in FFP.
FISSION TRACK ANALYSIS OF DETRITAL APATITES FROM SITES 859 , 860 , AND 862 , CHILE TRIPLE JUNCTION

Fission track analysis of detrital apatite grains recovered from sediment samples of upper Pliocene to Quaternary age from the Chile Triple Junction (Sites 859, 860, and 862), shows that the apparent ages of individual grains are older than the stratigraphic ages. The apatite fission track data indicate that there has been no significant postdepositional heating (i.e., maximum paleotemperatures have never exceeded ~60°C). The apatite grains, therefore, derive their fission track characteristics from the source area. The mineral assemblages are similar in all samples and indicate that this source area was dominated by crystalline basement and a volcanic terrain. The track-length distributions characterized by relatively long means (13-14 μm) are a significant feature of the fission track data, given that the apatite grains were eroded from mixed sources of a known broad age range. These data record moderately rapid cooling through ~ 110°C, which we attribute to moderately rapid uplift and erosion of the source area, followed by transportation and deposition of the sediment. Two distinct age populations are recognized in the combined samples from each of the three sites. The younger population is represented by a fission track age of -7 ± 2 Ma, whereas the older population gives an age of -25 ± 5 Ma. The younger age group is interpreted as revealing the time of moderately rapid cooling, produced by uplift and erosion of the source area. Recognition of this late Miocene (~7 Ma) event in the fission track data coincides with several major processes, including magmatism and tectonism, which have been documented already in the area. Erosion of the source (arc-forearc) region at this time is most likely a direct result of tectonic uplift caused by collision and subduction of one or two segments of the Chile Ridge. The older age (-25 Ma) identified in the fission track data records a discrete cooling event which we interpret as denudation and/or deformation of the forearc-arc region as a consequence of oblique convergence at the Chile margin.
Microbiological comparison of microwave and traditional thawing processes for poultry meat

Health agencies official has been convinced of the efficiency of microwave based process mainly due to its bactericidal property and safety (non-ionizing radiation). However, many biotechnological aspects of this new method are still unknown and have raised safety concerns. This study aimed to validate the application of the thawing process of a large poultry meat block under high frequency microwave oven (2.45 Ghz within 60 s). Compared to the traditional thawing method (4°C for 48 h), we combined a visual observation and bacteriological analysis. The microwave thawing process was clearly faster than the conventional process, by at least three times. Both microwaved samples and control samples complied with the standard requirements, even after five weeks of microbial-screening of total mesophilic flora, fecal coliforms, sulfite-reducing anaerobic, Staphylococcus aureus and Salmonella. In the exposure to microwave, there was also less loss of water compared to the traditional method (2.33±0.21 l < 3.45±0.21 l). Although it showed overheating signs due to the high frequency used, it did not compromise the shelf life of the product. We validated the microbial-safety of the microwave thawing process; however, adjusting the frequency would result in better quality output and alleviate side effects in the frozen poultry. Key words: Thawing process, poultry meat, chicken, microwave oven, quality management.
Application of adaptive optics on the satellite laser communication ground station

The advance of satellite to ground laser communication station using adaptive optics (AO) is summarized. Adaptive optics is the dominant technology to solve the atmosphere induced coherence degradation and availability reduction in the USA and Europe researching relay satellites. Key technologies, such as adaptive optics, muti-ground station receiving in day and night, and coherent communication are planned to test in these projects. It indicates that the satellite to ground laser communication is advancing to the engineering application with high date rate coherence and round-the-clock high availability. Several satellite to ground laser communication experiments have been successfully carried out in domestic, and the high availability coherent laser communication test is in progress. Adaptive optics technology has been applied in several ground stations and pretty results are obtained in the preliminary experiment. The related technology progress keeps in the same level with the foreign countries.
Short‐term changes in body condition in relation to habitat and rainfall abundance in American redstarts Setophaga ruticilla during the non‐breeding season

In migratory birds, environmental conditions during the stationary period of the non-breeding season are crucial to consider because they ultimately affect the fitness of individuals by influencing their subsequent migration, breeding success and survival. Although a few studies have investigated the influence of non-breeding habitat on the capacity of individuals to cope with long-term seasonal rainfall fluctuations, it remains unknown how habitat quality and variations in rainfall abundance at a monthly scale interact to affect non-breeding condition of migrating birds. In this study, we examined the influence of monthly changes in rainfall abundance on body condition of non-breeding female redstarts Setophaga ruticilla living either in a high quality habitat (mangrove) or in a low quality habitat (scrub). Body condition of both mangrove and scrub redstarts showed important variations over the study period, demonstrating for the first time that body condition of non-breeding female redstarts can change rapidly in response to short-term fluctuations in rainfall. Importantly, we found that female redstarts living in mangrove were usually in better condition during periods of low rainfall compared to females living in scrub. However, body condition did not differ between mangrove females and scrub females during an episode of frequent, heavy precipitation. Importantly, our study also demonstrated that the duration of a perturbation is an important determinant of body condition in redstarts since a prolonged drought resulted in similar low body condition for birds from both habitats. Age was not correlated with body condition whatever the habitat and the rainfall conditions. Our results demonstrate that high quality habitat can temporarily reduce the deleterious effect of a short-term drought on body condition, but also, that a habitat of low quality does not constrain individuals when climatic conditions are optimal.
Fish aggregating devices (FADs): good or bad fishing tools? A question of scale and knowledge - FOREWORD: Tahiti International Conference “Tuna Fisheries and FADs”, November 2011

It is estimated that fish aggregating devices (FADs) are now used for over 40% of world tropical tuna catches, making this technique a major phenomenon for high seas fisheries worldwide, and one that has experienced great expansion over the past three decades. The question of whether the FAD is a good or a bad tool for the exploitation of marine resources depends on many parameters. To respond to this question, it is necessary to distinguish different scales of exploitation (artisanal vs. industrial) and various types of FADs (anchored vs. drifting), but it is also very important to gather more data and conduct further research on this topic to gain a better understanding of the phenomenon and of its impacts. As such, twelve years after the first international conference devoted to FADs, which was held in Martinique (French West Indies), a new multi-scalar global assessment of FAD fisheries development and a review of the progress of research in this field was deemed vital. The latest international conference, “Tuna Fisheries and Fish Aggregating Devices”, was held in Tahiti in November 2011, and it was an event that welcomed nearly 150 conference attendees from 40 different countries, three ocean regions, and the Mediterranean. This is an analysis of the relevant literature gathered by the author in the bibliographic database FADBASE. Then, the major issues already addressed by the scientific community are set out, and gaps and research priorities are highlighted for anchored and drifting FADs management.
