Petroacoustic Characterization of Reservoir Rocks for Seismic Monitoring Studies. Laboratory Measurement of Hertz and Gassmann Parameters

The production of oil and gas reservoirs, or the storage of gas in geological formations, always has direct repercussions on the fluid content and pore pressure, and hence on the seismic properties of reservoir rocks. This article describes the laboratory methods used to measure the effect of variations in differential pressure and saturating fluid on elastic wave propagation velocities in reservoir rocks. The pressure effect is easy to measure in the laboratory, via the Hertz coefficient, exponent of the power function linking the velocity to the differential pressure. It is difficult to estimate the representativity of core samples that have undergone the sudden stress relaxation caused by coring. A statistical comparison of the measurement results on surface samples and core samples confirms the reality of this damage. The values measured in the laboratory are often values from above. They are very useful for setting the upper bounds of the anticipated effect of differential pressure. This effect is often negligible in many limestone reservoirs. It may be high or overpressurized in shallow sandstone reservoirs (underground storage facilities). The effect of the saturating fluid is quantified by the Gassmann formula, the value of which is usually confirmed by experiment. The use of this formula requires the knowledge of certain elastic properties of the rock. These moduli can be determined at the laboratory. We propose an original method that is also simple in principle, based on the experimental measurement of the quasi linear relation predicted by the Biot-Gassmann theory, between the bulk modulus Ksat of the saturated rock and the bulk modulus Kfl of the saturating fluid. In sandstones, during substitution experiments, the liquids used must not disturb the clay minerals (and weathered feldspars). Apart from the case of perfectly clean sandstones, it is therefore highly preferable to preserve an irreducible saturation of brine (Swi) and hence to work with two-phase saturation (brine/hydrocarbons). In limestones, which usually contain no clay, fluid substitution experiments are facilitated by the possibility of single-phase flushing by liquids with highly varied bulk modulus. The advantage procured by this experimental expedient is unfortunately diminished by the difficulty of signal processing caused by the "path dispersion" mechanism corresponding to the scattering on heterogeneities of nonnegligible size compared with wavelength. These heterogeneities (obviously associated with the complex diagenesis of limestones) are omnipresent but not always detectable by a conventional petrographic study. The use of phase velocities in processing transmitted signals is the safest means to help solve this difficulty. In the case of rocks of simple mineralogical composition (limestone, clean sandstone), the knowledge of the bulk modulus of the solid matrix Kgrain offers an excellent means to check the results, thereby substantially facilitating interpretation.
Measuring PV Module Performance at Different Tilt Angles in Southern Iraq Based Simulation

This paper presented that how to calculate the tilt angles and solar irradiance on photovoltaic (PV) module in southern Iraq (latitude 30° N). The latitude and day number of the city is taken into account to calculate the tilt angle and solar irradiance by using a mathematical equation. The optimum tilt angles of PV module in southern Iraq are range from 38° to 84°. The yearly maximum total and average solar irradiance is needed to determine the optimum tilt angle of PV module. The result shows that 50° of tilt angle is the best performance of PV module in southern Iraq.
Games with Incomplete Information on One Side as Games with Incomplete Information on Both Sides and Asymmetric Computational Resources

Decision-making under uncertainty in the Iowa Gambling Task (IGT) has been intensively studied over the last twenty years regarding both “hot” and “cold” components. The ventromedial prefrontal cortex is a key region involved in processing somatic marker information, though recent findings suggest that dorsolateral regions are also important. The dorsolateral prefrontal cortex is also known as a substrate of executive functions—the cold component of decision-making. However, there is contradictory evidence about the role of executive functions, as well as the hot component of decision-making—emotional intelligence. This study seeks to address this inconsistency. Previous findings suggest that patients with right frontal lobe lesions should find decision-making more problematic in IGT. This article investigates the importance of emotional intelligence as the hot and executive functions as the cold components of decision-making in IGT. We obtained data from patients with right frontal lobe tumours and healthy controls who undertook IGT, Wisconsin Card Sorting Test (WCST) and D-KEFS Colour-Word Interference Test. The current findings imply that performance in IGT is highly correlated with several parameters of set-shifting in the WCST: correct answers, conceptual level responses and non-perseverative errors. However, no correlation is found with cognitive inhibition parameters in the Colour-Word Interference Test, while an interaction between the emotional intelligence parameters and the performance on IGT is low.

Value Stream Mapping Methodology for Lead Time Reduction: A Review

In today’s global competitive world, the era of mass production and pull system is over. Now customer satisfaction is prime objective as they compare value of the money and the value they received from that money. They will not pay for any waste. Thus, Value Stream Mapping (VSM) is one of the best and most common tools of lean manufacturing to identify and eliminate wastes. FVSM helps to reduce NVAs in a process and make a production flow efficient, effective and economic. This paper discusses methodology to implement value stream mapping and its benefits to various production industries as well as in service sectors. This paper also represents a literature review to summarize various applications of VSM. The paper concludes with highlighting VSM’s contribution to delight customers.
Production of agarwood fragrant constituents in Aquilaria calli and cell suspension cultures

Calli and suspension cell culture were established from Aquilaria species whose resinous portion was called agarwood and used as medicine and incense. Four different strains of calli were analyzed for fragrant compounds such as sesquiterpenoids and chromone derivatives which were the major components of agarwood. Main sesquiterpenoids detected from calli were a -guaiene, a -humulene and d-guaiene, and those of chromone derivatives were phenylethylchromones (AH3, AH4, AH5, AH6). Amount of these compounds differed among the four strains, indicating that Aquilaria plants may have variation in capacity for fragrant compound production. Incubation temperature analysis was also done from 20°C to 40°C and resulted that cell growth was the best at 25°C, whereas the amount of fragrant compounds was largest at 20°C. Salicylic acid (SA) and methyl jasmonate (MJ) were added to calli and suspension cell culture respectively in order to induce production of fragrant compounds. Both SA and MJ apparently induced production of three sesquiterpenoids, a - guaiene, a -humulene, and d-guaiene at early stage of treatment of SA or MJ, but did not induce that of chromone derivatives directly. Further studies of time course of chromone production and cell viability suggested that cell death may take part in chromone production, and that phenylethylchromones would be produced via oxydoagarochromones (OACs). These results indicate that sesquiterpenoids are synthesized in living cells, but chromone derivatives may be produced from debris of dying cells.
ARSENIC UPTAKE AND PHYTOTOXICITY OF T-AMAN RICE GROWN IN THE SOIL OF BANGLADESH

A pot-culture experiment was conducted with T-aman rice (Oryza sativa L.) named BR-22 in arsenic (As) amended soil (0, 1.0, 5.0, 10.0, 20.0, 30.0, 40.0 and 50.0 mg kg-1As) in Bangladesh. Experimental results revealed that addition of As to soil affected plant height, tiller and panicle numbers, grain and straw yield of T-aman rice significantly (p ≤ 0.05). Plant height and straw yield was reduced significantly at low level of As in soil (1.0 mg kg-1) but grain yield was not affected up to 5.0 mg kg-1 As treatment. In 50 mg kg-1 As treatment, grain and straw yield was found to reduce 93.1% and 77.2%, respectively as compared to control.A high grain As uptake (1.29 ± 0.04 to 1.62 ± 0.05 mg kg-1As dry weight) was observed in the treatments of 30-50 mg kg-1 As containing soil. These levels exceed the food hygiene concentration limit of 1.0 mg kg-1As. However, the straw As uptake varied significantly (p ≤0.05) from a low concentration of As in soil (5 mg kg-1) and the highest up take (2.26 ± 0.10 mg kg-1As) was noticed in 20 mg kg-1 As treatment, and later the accumulation was found to decline.

STBCs originally introduced by Alamouti, have evolved as a revolution coding scheme in modern wireless communication field. Here, after presenting a general overview of MIMO systems, we will compare the performance results of STB codes of various diversity orders through computer simulations. Then we will determine the optimum diversity order of STB codes for the MIMO systems.
Not Me: Collaboration and Co-production with Language Processing Systems

This paper explores the use of language processing technologies for interactive artwork and studio art production. I consider text in multiple roles: as data, as index, and as a medium for interaction. After describing initial efforts with a dysfunctional chatbot, I discuss my recent work with language processing in the creation of studio art objects, and speculate about the extension of those techniques to address the large corpora of personal media we accumulate online.
Analysis of different tapering techniques for efficient radiation pattern

Array antennas offer a wide range of opportunities in the variation of their directivity patterns through amplitude and phase control. Peak side lobe levels may be reduced via amplitude control or weighting across the array aperture. Several authors have made significant contributions in detailing processes for synthesizing these aperture amplitude distributions for the purpose of side lobe level control. One of the basic trades-offs when implementing amplitude weighting functions is that a trade between low side lobe levels and a loss in main beam directivity always results. In this paper we are implemented and compare the Binomial array, Dolph-Tchebyscheff array and Taylor-Line Source array antennas. Descriptions of the amplitude tapers and their utility will be presented.

Analysis of inland mode choice decision for imported waterborne cargo from New York & New Jersey ports

Accessibility to ports and their residential and industrial vicinities are constrained by truck congestion, whereby the truck share of transporting export/import shipments in comparison to alternative modes is quite significant. Despite port surrounding areas at least recognizing what is occurring to their accessibility and economic performance, the academic world has not yet taken much notice. Previous studies on mode choice and modal competition mainly focused on intercity movement of domestic trade, but scarce empirical studies have addressed additional choices for inland traffic of export and import waterborne freight fully dedicated to containerized trade. This study is intended to fill this gap by investigating the mode choice for inland movement of non-containerized imported waterborne shipments from the New York & New Jersey port complex. A logit mode choice model for truck and rail is estimated using 2194 non-containerized shipment samples from the Commodity Flow Survey 2007 database. These shipments were imported from EU and Asia and dispatched to the respective inland destinations via both modes available. According to results, mode choice is primarily affected by the difference between the two modes’ freight rates and transit times. In the model it was identified that commodities imported from the EU, even though homogenous, have a higher chance of being shipped by rail. In the current study, marginal effects and elasticities were employed to investigate the average level of changes in mode probability as a result of certain modifications in explanatory variables.
The Relationship between External Mechanisms of Corporate Governance and Dividends Policy (Companies Accepted in TSE)

This paper investigates the effects of corporate governance mechanisms on dividends policy. Corporate governance is examined by external corporate governance variables such as government influence, the amount of minor shareholder (flow share), the ownership percentage of major shareholder and the amount of institutional shareholders. Panel data method is used on 101 companies which are accepted in TSE (Tehran Security Exchange) during 2004-2011. The results show that government influence, the amount of minor shareholder (flow share) and the amount of institutional shareholders have an inverse and meaningful relationship with dividends policy but the number of institutional investors has no meaningful relationship with dividends policy.
Risk Factors for Mortality in Dengue Shock Syndrome (DSS)

Background: Dengue shock syndrome (DSS) is the most severe form of dengue hemorrhagic fever (DHF) and has a high mortality. There are two major pathological changes in DHF determining the severity of disease, plasma leakage and bleeding. Cytokines released during the immune response to dengue virus have been thought to be mediators of the process. Methods: The study involved 50 children with DSS, of whom 13 (26%) died. We investigated which clinical signs and laboratory findings are related to mortality. Results: We found that gastrointestinal bleeding and bilateral pleural effusion were significantly more frequent in non-survivors than in survivors (p<0.02 and p=0.0006, respectively). Also, mean admission levels of thrombin-antithrombin complexes (TATc) and plasminogen activator inhibitor type 1 (PAI-1), activation markers of coagulation and fibrinolysis, respectively, were significantly higher in non-survivors (p=0.004 and p=0.0006, respectively). In regression analysis, bilateral pleural effusion and admission levels of TATc were significantly associated with mortality (p=0.007 and p=0.048, respectively). Conclusions: Our data provide evidence for a relationship of mortality with pleural effusion, a marker of plasma leakage, and coagulation activation, both characteristic pathological changes in dengue shock syndrome. Keywords: Dengue shock syndrome, mortality, risk factor. ABSTRAK Faktor risiko kematian pada demam berdarah dengue dengan sindroma syok (DSS) Latar belakang: DSS merupakan bentuk klinik yang paling berat dari demam berdarah dengue (DBD) dan mempunyai angka kematian yang tinggi. Terdapat dua kelainan patologik utama pada DBD yang menentukan beratnya penyakit, yakni kebocoran plasma dan perdarahan. Sitokine yang dilepas sewaktu terjadi respon imun virus dengue diduga merupakan mediator proses ini. Metode: Studi dilaksanakan pada 50 penderita DSS anak, dimana 13 (26%) diantaranya meninggal. Investigasi dilakukan untuk mencari temuan klinik dan laboratorik yang berhubungan dengan kematian. Hasil: Perdarahan gastrointestinal dan efusi pleura bilateral secara bermakna lebih banyak ditemukan pada penderita yang meninggal dibandingkan dengan penderita yang hidup (berturut-turut p<0,02 dan p=0,0006). Rerata kadar thrombin-antithrombin complexes (TATc) sewaktu masuk rumah sakit dan kadar plasminogen activator inhibitor type 1 (PAI-1) juga merupakan petanda aktivasi koagulasi dan fibrinolisis, secara bermakna (berturut-turut p=0,004 dan p=0,0006) lebih tinggi pada penderita yang meninggal. Pada analisis regresi didapatkan bahwa efusi pleura bilateral dan kadar TATc sewaktu masuk rumah sakit berhubungan bermakna dengan kematian (berturut-turut p=0,007 dan p=0,048). Simpulan: Data dari studi ini membuktikan adanya hubungan antara kematian dan efusi pleura bilateral (suatu petanda kebocoran plasma) dan aktivasi koagulasi dimana keduanya merupakan kelainan patologik khas untuk DSS.
Housing Discrimination among a Sample of Aboriginal People in Winnipeg and Thompson, Manitoba

There is a paucity of research on housing discrimination in Canada, generally, and even less research on housing discrimination among Aboriginal people—despite the related critical policy issues. Housing discrimination occurs when a group of people are denied equal access to housing. Typically, this discrimination involves the restriction of choices in renting or owning accommodations. There is a consensus among Canadian researchers that Aboriginal people have experienced sustained and widespread housing discrimination even though there are federal, provincial, and constitutional laws and provisions that protect equal access for all ethnic racial groups (Beavis 1995; Quann 1979). Aboriginal people’s access to housing has historically been a controversial policy issue. However, it has become a more complex issue since the large scale migration of Aboriginal people to urban centres throughout Canada. Unlike the housing issues on reserves, housing in the urban context typically involves far more subtle forms of discrimination. In turn, developing effective policy responses is particularly challenging, especially given the different municipal, provincial, and federal jurisdictional issues. Given that the Aboriginal urban migration trend will continue and that available housing will also continue to be limited and expensive, it is vital to understand the types of housing discrimination that exist and how Aboriginal migrants perceive their attempts to access housing. In effect, government housing policies need to be informed by systematic empirical research concerning the contemporary Aboriginal housing experience. Clatworthy (1996) examined the migration, residential mobility, and housing patterns of Canadian Aboriginal people between 1986 and 1991. He found that Aboriginal people moving to urban centers are more commonly: female; younger; include large numbers of families with small children; and have less formal education than their non-Aboriginal counterparts.

Spatial-homogeneity of stable solutions of almost-periodic parabolic equations with concave nonlinearity

We study the spatial-homogeneity of stable solutions of almost-periodic parabolic equations. It is shown that if the nonlinearity satisfies a concave or convex condition, then any linearly stable almost automorphic solution is spatially-homogeneous; and moreover, the frequency module of the solution is contained in that of the nonlinearity.
The added value of neuromarketing tools in the area of marketing research

The knowledge about the brain and therefore the interest in the topic of neuromarketing has increased in recent years. Therefore the purpose of this paper is to examine the added value of neuromarketing tools in the area of marketing research. There is no literature which includes all the aspects of marketing research and the added value of neuromarketing tools to these aspects. In regard to the topic of neuromarketing this study will be done on the basis of a critical literature review. The inability of people to describe their feelings as a method of self-assessment is one of the most important reasons why neuromarketing could be useful. Another reason mentioned is that the brains of people also contain hidden information about their true preferences. Such information can be used to influence their buying behaviour. After a brief explanation of the neuromarketing techniques like the outside reflexes, input-/output models and the inside reflexes, this paper examines the added value of these neuromarketing tools in the area of marketing research. The results indicate a positive contribution of neuromarketing tools to the aspects of identifying the customers’ needs and wants and to all four aspects of the integrated marketing program: product, price, distribution and promotion. Therefore it may be concluded that neuromarketing adds a lot of value to the marketing research area.
A Study of Particle Swarm Optimization with Considering More Local Best Particles

The velocity updating formula of the standard particle swarm optimization (PSO) only considers two particles: the local best particle and the global best particle. The global best particle can be viewed as the optimal one of all local best particles. In order to improve the optimizing performance and exploit all existing resources as fully as possible, we further study other local best particles how to affect the results of optimization in this paper. Experimental results show that a suitable selection of the number of local best particles will result in higher performance.
The Microscopic Structure and Chemistry of Rapeseed and its Products

The location and distribution of some of the storage constituents in the structures of rapeseed and its products were investigated. Hand-cut or glycol methacrylate-embedded sections were stained with dyes or fluorochromes of known specificities and examined using fluorescence, bright-field and/or polarizing microscopy. Results obtained from the study were based upon observations of characteristics of the various stainings, birefringence, induced fluorescence and autofluorescence. The effects of enzymatic hydrolysis, solvents and processing on the cellular structures and their affinity for certain dyes/ fluorochromes were also investigated. Major and minor storage constituents were tentatively located in the structure of rapeseed. Lipids and proteins were stored within separate cellular organelles which were distributed throughout the aleurone layer of the endosperm and cells of the embryo. These two accounted for the major portions of rapeseed storage reserves. Phytin crystals were detected inside the protein bodies of the embryonic cells. Most of the rapeseed polysaccharides were present as structural (cellwall) carbohydrates of which amyloid was one of the major components. The seed coat of rapeseed is a complex structure containing structural carbohydrates, mucilage and lignin. The testa of the yellow seed-coated cultivar, Candle, was structurally and chemically different from that of other rapeseed varieties. Initial paper received February 3, 1982.
