Abstract

The article presents a comprehensive economic analysis of a CO2 injection project in one of the Polish oil fields for both increased production (CO2-EOR) and underground storage (CCS). An interesting differentiator of this work is the use of a multilayered reservoir, which is actually not one reservoir but several located in the same place, as an example. It allows the optimization of the processes of injection, production and storage. Such projects are becoming more and more important because recently, after a period of long-term stagnation, costs of carbon allowances have started to rise which affects e.g. the electricity market in Poland. This can be an important incentive for the development of CCS technology, especially in combination with CO2-EOR. In the case of very high costs of carbon emissions rights CCS may turn out to be a cheaper solution. Economic efficiency is the main determinant of the EOR project’s success, as well as a very significant factor influencing the potential development of CO2 underground storage. Results are based on the numerical simulation of a combined CO2-EOR and CCS project. This analysis has been divided into two parts. The first uses a standard, deterministic approach, based on the DCF method and NPV indicator. It also provides a detailed sensitivity analysis, with particular reference to the impact of oil prices and the cost of carbon emissions rights on a project’s profitability. The second part of the economic analysis is probabilistic and involves estimating the maximum amount of CAPEX using the Monte Carlo method. Two cases were taken into account. The first assumes that the CO2 emitter pays for CO2 storage and the price is equal to 80% of the emissions rights price (with storage revenue). In the second one the emitter does not pay for storage (without storage revenue).

Abstract

Love is the most widespread phenomenon at the individual, social and cultural level. Our knowledge of love comes both from our individual experiences and the social and cultural models that depict the nature of love in that particular era. There are a number of tools for measuring individual attitudes, feelings, manifestations, and behaviours relating to love. The Individual Representations of Love Scale is based on the fact that representations of love are created at the point where the individual intersects with the culture. The psychometric parameters of the Individual Representations of Love Scale were verified on a sample of 755 young people aged 18-35. Cultural resources and differentiation ability with regard to religious status, gender, and multiple partner relationship characteristics are taken into account. The results show that there are five factors of individual representations of love: 1. biological and selfcentred love, 2. spiritual love, 3. physical love, commitment, searching and building, 4. strength and positive benefits of love, and 5. reverse side of love. The cultural resources of these five factors and the scale’s differentiation ability are discussed.

Abstract

This research explored different types of two-phase flow patterns that influenced heat transfer rate by assessing rectangular two-phase closed thermosyphon (RTPCT) made from glass with the sides of equal length of 25.2 mm, aspect ratio 5 and 20, evaporation temperature of 50, 70, and 90 °C, working substance addition rate of 50% by volume of evaporator, and water inlet temperature at condensation of 20 °C. Upon testing with aspect ratios 5, three flow patterns emerged which were: bubble flow, slug flow and churn flow respectively. As per the aspect ratio 20, four flow patterns were discovered which were: bubble flow, slug flow, churn flow and annular flow, respectively. Aspect ratio 5 pertains characteristic which resulted in a shorter evaporation rate of the RTPCT than that of the aspect ratio 20, thus, a shorter flow distance from the evaporator section to heat releaser was observed. Therefore, flow patterns at aspect ratio 5 exhibited a faster flow velocity than that of the aspect ratio 20. Furthermore, changes of flow pattern to the one that is important for heat transfer rate can be easily achieved. Churn flow was the most important type of the flow for heat transfer, followed by slug flow. Moreover, with aspect ratio 20, annular flow was the most important flow for the heat transfer, followed by churn flow, respectively. Throughout the test, average heat flux as obtained from the aspect ratio 5 were 1.51 and 0.74 kW/m2 which were higher than those of the aspect ratio 20. The highest heat flux at the operating temperature of the evaporator section was 90 °C, which was equivalent to 2.60 and 1.52 kW/m2, respectively.

Abstract

Spectroscopy has become one of the most used non-invasive methods to detect plant diseases before symptoms are visible. In this study it was possible to characterize the spectral variation in leaves of Solanum lycopersicum L. infected with Fusarium oxysporum during the incubation period. It was also possible to identify the relevant specific wavelengths in the range of 380–1000 nm that can be used as spectral signatures for the detection and discrimination of vascular wilt in S. lycopersicum. It was observed that inoculated tomato plants increased their reflectance in the visible range (Vis) and decreased slowly in the near infrared range (NIR) measured during incubation, showing marked differences with plants subjected to water stress in the Vis/NIR. Additionally, three ranges were found in the spectrum related to infection by F. oxysporum (510–520 nm, 650–670 nm, 700–750 nm). Linear discriminant models on spectral reflectance data were able to differentiate between tomato varieties inoculated with F. oxysporum from healthy ones with accuracies higher than 70% 9 days after inoculation. The results showed the potential of reflectance spectroscopy to discriminate plants inoculated with F. oxysporum from healthy ones as well as those subjected to water stress in the incubation period of the disease.

Abstract

It has already been well established that long exposure to low doses of pesticidesis linked to consumer risks. So, this study purposed to investigate the amounts of pesticide residues and potential health risks associated with them. The risk assessment was determined by two methods: 1. Pesticide toxicity index (PTI) depending on the maximum residue limit (MRL) to calculate the hazard quotient (HQ); 2. Health risk assessment (HR) using acceptable daily intake (ADI) and estimated daily intake (EDI) to calculate the health index (HI). Pesticide residues were estimated in 176samples of the most popularly consumed vegetables collected from major retailers and markets in Dakahlia, Egypt (during 2018). There were 111 samples contaminated with pesticide residues (63.1%), of which 29 samples (16.48%) were higher than the maximum residue limits (MRL).Residues of 23 compounds were found in the analyzed samples, of which chlorpyrifos was the most frequentin 33 samples (18.75%);while cypermethrin was the lowest (detected in one sample). According to WHO toxicity classification, 12 of the detected pesticides were moderately hazardous (class II), seven pesticides belonged to class III (slightly hazardous), three compounds were found in class U (unlikely to pose an acute hazard with normal use), while carbofuran is a highly toxic compound (class Ib). Also, the obtained data revealed that, the HI’s for the individual pesticides ranged from 0.0018 to 64.0% of ADI indicates no risk of adverse effects following exposure to the individual pesticides. The cumulative exposure amounts (PTI values) ranged from 1.58 in snake cucumber to 128.44 in potato tubers, indicating that, the combined risk index of pesticide residues was a significant health risk for consumers according to the individual risk index.It can be concluded that there is a need for strict regulation and regular monitoring of pesticide residues in foodstuff for consumers’ health protection.

Abstract

Postharvest insect pests constitute major threats to food security because they cause qualitative and quantitative damage to agricultural produce. Therefore, eco-friendly and cost-effective measures should be used for their management. In this study, five botanical powders ( Trema orientalis and Crataeva religiosa leaves; and Citrus tangelo, Citrus maxima and Citrus aurantifolia peels) were admixed with Spintor® [1.25 active ingredient (a.i.) mg · kg –1] and evaluated as toxicants against Tribolium castaneum. Each botanical powder and spintor was solely applied at 1000 mg · kg –1 millet seeds. Spintor-botanical powder mixtures admixed at a ratio of 1 : 1 (w/w) were applied at 500 and 1000 mg · kg –1, corresponding to 0.313 and 0.625 a. i. mg · kg –1 for spintor in the mixtures, respectively. On the 14th day of exposure, the Citrus species admixed with spintor and applied at 500 mg · kg –1 evoked significantly (p < 0.05) higher percentage mortality (72.22–90.28%) than what was observed in the mixture of spintor with T. orientalis (22.08%) or the mixture of spintor with C. religosa (17.92%) applied at 500 mg · kg –1. There was a significant difference (p < 0.05) in the Kaplan-Meier estimates of the treatments against the insects. The time required to kill 50% of the assayed insects (LT50) when Citrus species were admixed with spintor at 500 mg · kg –1 (10 days) was shorter than 14 days observed in the mixture of spintor with T. orientalis or C. religiosa. Therefore, admixing spintor with any of the Citrus powders [at 1 : 1 (w/w)] applied at 500 mg · kg –1 seed is recommended for the protection of millet seeds against T. castaneum.,

Abstract

Using microorganisms in eliminating or reducing the impacts of harmful remnants is very ancient manner. The current study was conducted to explore the potential of utilizing some fungi species that isolated from the main sewage treatment plant in Al-Muamirah area, Babylon-Iraq, in reducing some pollutants. Six fungi taxa Aspergillus flavus, A. niger, A. terrues, Candida albicans, C. krusei, and Penicillium digitatum were identified before any treatment process, whereas only four fungi species A. flavus 20%, A. niger 20%, A. terrues 10%, and P. digitatum 18% were recognized after completing the physical and chemical treatment stages. Only three taxa A. niger, A. terrues, and P. digitatum were employed to reveal their capability in treating the sewage water, which represent the biological treatment stage as the final step of the treatment processes. The results showed a considerable capability of these fungi species in decreasing many variables values such as pH, total soluble solids (TSS), electrical conductivity (EC), salinity, total alkalinity, chlorides, nitrite, and phosphate. Where, slightly low reduction was detected in TSS value in all experiments (1.1–5.9%), similarly, both EC and salinity which were decreased with low ratios (6.6%, 3.9%, respectively). Taxon A. terrues exhibited high ability in reducing the total alkalinity and chloride ions in the treated water (30.9%, 43%, respectively) in comparison with the other two fungi species. Furthermore, all three fungi species were posed high capability in decreasing nutrients, where both nitrite and phosphate ions were highly reduced (87–97% and 22.8–32.1%, respectively). Based on these findings, we suggest using other microorganisms and exploring their capacity in removing the pollutants, and revealing the ability of the above fungi taxa in removing other pollutants.

Abstract

In the present study, a novel PVA–g–PMA hybrid membrane was developed for application in direct methanol fuel cell (DMFC). Maleic anhydride (MA) was grafted on polyvinyl alcohol (PVA) both ionically and chemically using potassium persulfate (KPS), for the first time. ThePVA–g–PMA thus synthesized was then blended with 3–Amino–4–[3–(triethylammonium sulfonato)phenyl amino]phenylene hydrochloride. The prepared membranes were characterized by FT–IR, TGA. 0.0104 S/cm of proton conductivity was found for the membrane. The ion exchange capacity was found to be 2.175 meq/g and the water uptake capacity as 14.9%. The single-chamber fuel cell power density was higher (34.72 mW/cm2) and current density (62.11 mA/cm2) when compared to Nafion 117 membrane.

Abstract

Fe-based bulk metallic glasses (BMGs) have been extensively investigated due to their ultrahigh strength and elastic moduli as well as desire magnetic properties. However, these BMGs have few applications in industrial productions because of their brittleness at room temperature. This study is focused on the effect of cooling rate on the mechanical properties (especially toughness) in the Fe41Co7Cr15Mo14Y2C15B6 BMG. For this aim, two samples with the mentioned composition were fabricated in a water-cooled copper mold with a diameter of 2 mm, and in a graphite mold with a diameter of 3 mm. The formation of crystalline phases of Fe23(B, C)6, α-Fe and Mo3Co3C based on XRD patterns was observed after the partial crystallization process. To determine the toughness of the as-cast and annealed samples, the indentation technique was used. These results revealed that the maximum hardness and toughness were depicted in the sample casted in the water-cooled copper mold and annealed up to 928°C. The reason of it can be attributed to the formation of crystalline clusters in the amorphous matrix of the samples casted in the graphite mold, so that this decrease in the cooling rate causes to changing the chemical composition of the amorphous matrix.

Abstract

The growing population and the development of industries in all countries of the world have created a very important and complex issue for water supply to cities. Today, many parts of the world are facing the problem of water shortage and this problem cannot be easily solved. In addition to the proper use of water resources and preventing the loss of natural water, the establishment of regional water supply networks is effective in meeting the future needs of the people. A water distribution network (water supply network) is a set of interconnected pipelines used to transport and distribute water in a complex. In designing the water distribution network, factors such as the type of water distribution network, water pressure, water velocity, design flow, minimum pipe diameter, pipe material and many other factors should be considered. In this study, we have tried to design the water supply network of a part of Balikpapan city in Indonesia. The design method led to the determination of pressure values in the connection nodes, pipe diameters, flow rate and velocity in the pipes. All the existing criteria are considered in the design of the water supply network. Although this study has been implemented for a specific study area, it can be of great help to designers in designing the water supply network.

The essay will focus on a mid-nineteenth century medallion from the vast collection of Polish bibliophile Ludwik Gocel (1889–1966). Made in 1854 in the U.S. capital, Washington, D.C., it depicts a prominent nineteenth century American, Judge Charles Mason (1804–1882), and is a valuable token of the U.S. history. It was designed and completed by Polish distinguished medalist, Henryk Dmochowski (in the U.S. known as Henry Dmochowski Saunders; b. 1810–d. 1863) who can be called a “soldier-artist,” since he participated in three Polish uprisings. Expelled from partitioned Poland, in 1851 he came to America where he was offered the chance to work as a sculptor. This essay’s main aim is to describe the fate of the medallion, apparently almost unknown in both America and Poland, with special emphasis on the role of Ludwik Gocel in its preservation. This rare piece of art has never been included in Polish or American art publications in the field of sculpture.

Abstract

The aim of this study was to investigate the effect of the addition of fungal solid-state fermented product (FP) enriched with gamma-linolenic acid (GLA) and β-carotene to feed on the haematological and immunological parameters of broiler chickens. Eighty 1-day-old COBB 500 broiler chickens were divided into two groups. The control group was fed with basic diets and chickens of the experimental group received 10% addition of FP, while the amount of basic diet was reduced. FP was produced during a solid-state fermentation (SSF) process using Umbellopsis isabellina CCF2412 as a producer of GLA and β-carotene. After 38 days of feeding, blood samples were collected and analyzed. Lower total and LDL-cholesterol values were measured in blood samples of the experimental animals (p<0.05). However, the triacylglycerol content was higher in the experimental group (p<0.05). Significantly higher levels of hematocrit and hemoglobin, and lower eosinophil and basophil content in the experimental group were recorded (p<0.05). The experimental group showed higher numbers of B lymphocytes and greater phagocytic capacity (p<0.05). The results indicate that a fermented product produced by SSF, using the fungal strain Umbellopsis isabellina, is a good source of GLA and β-carotene, which can influence the biochemical, hematological and immunological parameters of broiler chickens.

Abstract

51 samples from the Middle Triassic black shales (organic carbon−rich silt− stones; up to 4.9% TOC – Total Organic Carbon) from the stratotype section of the Bravaisberget Formation (western Spitsbergen) were analyzed with respect to isotopic composition of pyritic sulphur (δ34S) and TOC. Isotopic composition of syngenetic py− rite−bound sulphur shows wide (δ34S from −26‰ to +8‰ VCDT) and narrow (δ34S from −4‰ to +17‰ VCDT) variation of the δ34S in upper and lower part of the section, respec− tively. Range of the variation is associated with abrupt changes in dominant lithology. Wide δ34S variation is found in lithological intervals characterized by alternation of black shales and phosphorite−bearing sandstones. The narrow δ34S variation is associated with the lithological interval dominated by black shales only. Wide and narrow variation of the δ34S values suggests interplay of various factors in sedimentary environment. These fac− tors include oxygen concentration, clastic sedimentation rate, bottom currents and bur− rowing activity. Biological productivity and rate of dissimilatory sulphate reduction had important impact on the δ34S variation as well. Wide variation of the δ34S values in the studied section resulted from high biological productivity and high rate of dissimilatory sulphate reduction. Variable degree of clastic sedimentation rate and burrowing activity as well as the activity of poorly oxygenated bottom currents could also cause a co−occurrence of isotopically light and heavy pyrite in differentiated diagenetic micro−environments. Occurrence of organic matter depleted in hydrogen could also result in a wide variation of the δ34S values. Narrow variation of the δ34S values was due to a decrease of biological productivity and low rate of dissimilatory sulphate reduction. Low organic matter supply, low oxygen concentration and bottom currents and burrowing activity were also responsible for narrow variation of the δ34S. The narrow range of the δ34S variation was also due to occurrence of hydrogen−rich organic matter. In the studied section the major change in range of the δ34S variation from wide to narrow appears to be abrupt and clearly associated with change in lithology. The change of lithology and isotopic valuesmay sug− gest evolution of the sedimentary environment from high− to low−energy and also facies succession from shallow to deeper shelf. The evolution should be linked with the Late Anisian regional transgressive pulse in the Boreal Ocean.

Abstract

The Cracow districts have the status of auxiliary self-governing units within this city and, generally should be communities of residents living in particular parts of the city, close to them, in which they implement their daily practices. In theer article, the authors, by examining the sense of belonging to the district, undertook to identify its perception by residents and relations between the residents and their auxiliary units, on the example of two such districts this of VIII Dębniki and X Swoszowice. Attitudes of their residents towards self-governing districts were identified on the basis of 1141 questionnaires, obtaining during surveys conducted in 2017. The authors have found relatively weak relations of residents with their auxiliary units, as evidenced by small involvement in initiatives taken for the benefit of this districts. The analysis, however, showed also considerable differences in the detailed assessment of the attitudes of residents at the level of their division according to their age groups, period of the residence, as well as to the type of housing a single-family, multi-family or mixed ones.

Abstract

Gothenburg is the second-largest city in Sweden, capital of Västra Götaland County Region. It is situated on the west coast of Sweden with the port area located along the Göta Älv River. Due to economic restructuring, waterfront redevelopment emerges as an attractive option to boost economic growth of the city. The aim of this paper is to shed light on conditions of the transformation process of two neighboring areas: Frihamnen and Ringön. Publicly initiated and privately executed waterfront redevelopment in Gothenburg transforms industrial grounds into residential and service oriented areas in Eriksberg, Lindholmen and Frihamnen. The collaborative process of a “developer dialogue” crafts a redevelopment in a consistent way with taking into consideration city’s long-term planning strategy, specifi c needs and opportunities of the neighbourhoods, but also market and fi nancial realities of development community. Another example is a slow and spontaneous transformation of post-industrial areas in Ringön, where still active small industrial fi rms, services, cultural and artistic initiatives take place in the close proximity to the city centre. Results show the waterfront transformation attracts “developers’ dialogue” giving the opportunity to build a coherence for spatial, environmental and socio-economic development. Yet fragmented redevelopment of brownfi eld areas strengthen polarization between dynamic and carefully planned Frihamnen and spontaneously growing Ringön. This paper contributes to the knowledge on the complexity of urban post-industrial transformation.

Abstract

The revitalization of brownfi elds and post-industrial facilities is a long-term and multistage process. In the first stage of revitalization, it is important to assess the material, emotional and utilitarian value of the preserved cultural heritage. On the example of a revitalization project that has been ongoing since 1996, the former areas of the Gdańsk Shipyard, where the remains of the Imperial Shipyard and Schichau Shipyard are located, the process of formulating the value of the preserved cultural material heritage has been presented. The impact of this process on the subsequent stages of the revitalization of the Young City in Gdańsk was also presented. Gdańsk Shipyard is the cradle of Solidarity, so the emotional value associated with the events accompanying the creation of the Solidarity movement was considered to be the dominant one. Only two objects were entered in the register of monuments; BHP Hall and Solidarity Square (Plac Solidarności). When the Local Development Plan has been passed many investments have begun by various investors without comprehensive integrated activities. The demolition of the preserved halls and the dismantling of shipyard equipment began. This caused that in 2015 the uniqueness of the survived post-industrial complex, qualifying it for inclusion in the World Heritage list, was appreciated. In 2018, the Provincial Pomeranian Monument’s Conservator began the procedure of entry of the preserved objects to the register of monuments. This resulted in the suspension of all investments that commenced legally in the area covered by the proceedings. Lack of proper assessment of the cultural value of material heritage at the stage of preparing the revitalization process led to the loss of part of this heritage and caused increase of the investment activities risk in this area.

Abstract

The literature is undisputed regarding the impact of mental health on public health, and there has been an increase in the use of primary healthcare, in particular, the consultations of general practitioners (GPs), with issues at this level. In the literature on the subject, the psychological intervention has been indicated as a positive factor in reversing this trend, and it is in this context that the present study was developed. We intend to explore the differences in the number of GP consultations prior to and after the psychology consultation in a Primary Healthcare Centre (PHC). To this end, data from 845 healthcare center users were collected between June 2004 and September 2014. Student’s t-test and mixed analysis of variance (ANOVA) was performed. The results point out a decrease in the number of GP consultations in the period subsequent to the first psychological consultation. We discuss that psychological intervention seems to have a positive effect, not only in improving the mental health of the population but also in the containment of costs in the health sector. The importance of the role of psychology in PHC was assumed.

Abstract

Subspace-based methods have been effectively used to estimate enhanced speech from noisy speech samples. In the traditional subspace approaches, a critical step is splitting of two invariant subspaces associated with signal and noise via subspace decomposition, which is often performed by singular-value decomposition or eigenvalue decomposition. However, these decomposition algorithms are highly sensitive to the presence of large corruptions, resulting in a large amount of residual noise within enhanced speech in low signal-to-noise ratio (SNR) situations. In this paper, a joint low-rank and sparse matrix decomposition (JLSMD) based subspace method is proposed for speech enhancement. In the proposed method, we firstly structure the corrupted data as a Toeplitz matrix and estimate its effective rank value for the underlying clean speech matrix. Then the subspace decomposition is performed by means of JLSMD, where the decomposed low-rank part corresponds to enhanced speech and the sparse part corresponds to noise signal, respectively. An extensive set of experiments have been carried out for both of white Gaussian noise and real-world noise. Experimental results show that the proposed method performs better than conventional methods in many types of strong noise conditions, in terms of yielding less residual noise and lower speech distortion.

Abstract

Many precision devices, especially measuring devices, must maintain their technical parameters in variable ambient conditions, particularly at varying temperatures. Examples of such devices may be super precise balances that must keep stability and accuracy of the readings in varying ambient temperatures. Due to that fact, there is a problem of measuring the impact of temperature changes, mainly on geometrical dimensions of fundamental constructional elements of these devices. In the paper a new system for measuring micro-displacements of chosen points of a constructional element of balance with a resolution of single nanometres and accuracy at a level of fractions of micrometres has been proposed.

Abstract

The article addresses the problem of properties and epistemic functions of Russellian ‘knowledge by acquaintance’ interpreted here as a variant of intuition. The epistemic functions of intuition can be performed in two ways: first, as propositional knowledge of direct and immediate kind (a foundational function), and secondly, as a non-‑propositional form of consciousness that provides a justifying basis for intuitive truths. The distinction between these two functions of intuition presupposes a differentiation – not explicitly articulated by Bertrand Russell – between acquaintance and knowledge by acquaintance. Acquaintance as a form of non‑propositional consciousness is not epistemically autonomous, which is to say that it is not a judgment and cannot be qualified as either true or false, so a separate epistemic problem arises here, one of the shift from acquaintance to knowledge by acquaintance. The author points out that the shift from acquaintance to knowledge by acquaintance is difficult to accomplish, and she offers the opinion that the epistemic function of acquaintance or, more generally, of various similar kinds of consciousness, should not be interpreted in terms of justification. They should be understood not as a justifying element or a justifying reason for propositions that underlie other propositions, but as a factor that is an indispensable genetic and simultaneously structural element of propositional content in the sense assumed in transcendental philosophy.

Abstract

Narrative synergies – Christ stopped at Eboli: The writing of Carlo Levi in the view of Francesco Rosi – In Christ Stopped at Eboli, Carlo Levi recounts his confinement in a recondite village of southern Italy, in an archaic world, by which he remains completely fascinated. In 1978, the director Francesco Rosi, adapting the documentary structure to the lyric moments of the literary text, offers us a wonderful film re-creation in which the intense autobiographical story of the anti-fascist writer intersects with geographical space at a historical moment crucial to Italy.
