Opis:
This study is a response to an ongoing debate on changes in the taxation of agricultural income. The current taxes applicable to farms in Poland do not concern income per se – they are property taxes which include: agricultural tax on land, forestry tax and property tax. Although these taxes do not refer to agricultural income, they are paid by it. It is important, therefore, to know how much this income is reduced by these taxes. Studies show that it is about 10%. Therefore, when a new income tax structure is introduced, its rate should not exceed 10%. The calculation of farm income in Poland will encounter many problems, such as establishing a catalogue of costs, which will include depreciation. In order to include it when calculating income, the present value of a farm’s fixed assets should first be established, which may encounter major substantive and organizational difficulties. More problems will surely follow, such as: dividing costs between household and agricultural holding, determining what a fixed asset is in the case of a farm, etc. It seems that calculating farm income is unavoidable. On the one hand, it is necessary for the potential introduction of income tax. On the other hand, having recognized the income situation of farms, one could resign from estimating losses caused by drought or other unfortunate events. Compensation could be granted due to income losses. This would be a clearer, more obvious and objective criterion. According to current practices, losses caused by unfortunate events (e.g. drought) do not always translate into losses in agricultural income, given that these losses are not always objectively estimated by the committees appointed by provincial governors. In the case of income losses, agricultural accounting data guarantee their objective appraisal. The aim of the paper is to evaluate the current situation regarding the taxation of agricultural activity and to present proposals for potential changes in the taxation of agricultural activity. Two research hypotheses were put forward: 1. the current level of taxation of income and revenue from agricultural activity with agricultural tax and property tax is symbolic, 2. in order to maintain the current tax treatment, the rate of the new tax on farm income cannot be higher than 10%. The article is based on descriptive, tabular and financial analysis methods. The sources of information were literature and FADN agricultural accounting data collected by the Institute of Agricultural and Food Economics – National Research Institute in Warsaw.
Opracowanie wychodzi naprzeciw toczącym się dyskusjom w sprawie zmian opodatkowania dochodów pochodzących z działalności rolniczej. Aktualnie istniejące podatki, odnoszące się do gospodarstw rolnych w Polsce, nie odnoszą się do dochodów. Mają one charakter podatków majątkowych, do których należy: podatek rolny od gruntów, podatek leśny i podatek od nieruchomości. Podatki te mimo, że nie nawiązują do dochodów z działalności rolniczej, są z nich pokrywane. Ważnym jest jaką część tych dochodów pomniejszają. Z badań wynika, że jest to ok. 10%. Stąd ewentualnie we wprowadzanym nowym podatku od dochodów jego stawka nie powinna przekraczać 10%. Obliczanie dochodów gospodarstw rolnych w Polsce będzie napotykać na wiele problemów. Jednym z nich będzie ustalenie katalogu kosztów, do których zaliczać będzie się amortyzacja. Aby ją uwzględnić w obliczaniu dochodów, należy wcześniej ustalić wartość bieżącą środków trwałych, wchodzących w skład gospodarstw rolnych. Mogą temu procesowi towarzyszyć spore trudności merytoryczne i organizacyjne. To jeden z wielu problemów. Prawdopodobnie będą i inne. Zaliczyć do nich można: podział kosztów na gospodarstwo domowe i gospodarstwo rolne, ustalenie co jest środkiem trwałym w gospodarstwie rolnym itp. Wydaje się, że liczenie dochodów w gospodarstwach rolnych jest nie uniknione. Z jednej strony jest to niezbędne dla ewentualnego wprowadzeniu podatku dochodowego. Z drugiej strony mając rozpoznaną sytuację dochodową gospodarstw rolnych można by zrezygnować z szacowania strat spowodowanych przez suszę, czy innymi zdarzeniami losowymi. Tytułem otrzymania rekompensat byłyby straty dochodów. Jest to kryterium bardziej klarowne oczywiste i obiektywne. Dotychczasowa praktyka wskazuje, że nie zawsze straty spowodowane zdarzeniami losowymi (suszę) przekładają się na straty w dochodach rolniczych. Zważywszy, że straty te nie zawsze są obiektywnie szacowane przez powoływane przez wojewodów komisje. W przypadku strat w dochodach, dane rachunkowości rolnej są gwarantem ich obiektywnej oceny. Celem opracowania jest dokonanie oceny aktualnej sytuacji dotyczącej opodatkowania działalności rolniczej oraz przedstawienie propozycji ewentualnych zmian w opodatkowaniu działalności rolniczej. Przyjęto dwie hipotezy badawcze: 1. Aktualny stopień opodatkowania dochodów, przychodów z działalności rolniczej podatkiem rolnym, podatkiem od nieruchomości jest symboliczny, 2. Dla zachowania dotychczasowego ujęcia podatkowego stawka nowego podatku od dochodów gospodarstw rolnych nie może przekraczać 10%. W artykule wykorzystano metody analizy opisowej, tabelarycznej i analizy finansowej. Źródłem informacji była literatura oraz dane rachunkowości rolnej FADN gromadzone przez Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej – Państwowy Instytut Badawczy w Warszawie.

Opis:
Observations of the shelf environment rarely associate internal solitary waves (ISWs) with the impact of their passage. An experiment observed during the Coastal Mixing and Optics 1996( CMO ’96), a sequence of long internal waves on a coastal shelf is reported, including both mode-1 and mode-2 waves, together with evidence related to the interaction of propagating ISWs and the benthic boundary layer. The observed ISW dynamics is shown to present a repetitive pattern or ‘climate cycle’. The ISW-associated benthic signature described here occurs frequently (at least once a day) in the CMO ’96coastal area and suggests that ISWs under calm, summer-like conditions may have a decisive influence on the fate of near-bottom pollutants or biological processes in shelf regions.

Opis:
The Airy beams propagation in atmospheric turbulence along a slant path was simulated numerically, based on the split-step Fourier method. Also, the self-repairing and non-diffraction characteristics of Airy beams were investigated and compared with beams propagation on a horizontal path. The effects of parameters including zenith angle, propagation distance, radii of Gaussian aperture and turbulence intensity on the two characteristics of beams were revealed. Additionally, the two characteristics of the Airy beam were compared with those of a Bessel–Gauss beam. The results showed that the two beams obscured by Gaussian apertures can be repaired after propagating some distance along a slant path. However, the non-diffraction characteristic of an Airy beam was stronger than that of a Bessel–Gauss beam and the amplitude attenuation rate of the Bessel–Gauss beam was greater than that of the Airy beam in the process of self-repairing. Results obtained can provide a theoretical basis for an outdoor experiment as well as theoretical guidance for various practical applications including laser communications, laser warning systems, and remote sensing.

The preliminary results suggest that moral adjectives don’t fall neatly under either category. In the second part we tackle the question of the scale of moral adjectives in a more theoretical fashion, i.e. by investigating their possible scales with mathematically precise tools.

The stable innovation system generation is one of the Russian economic policy priorities. Universities have the role of a central hub in the regional innovation systems formation. This article presents a study of factors influencing the formation and development of the university’s innovation environment and examples of innovation activities of the Krasnoyarsk State Pedagogical University V.P. Astafyev (KSPU) in the regional innovation ecosystem of social assistance. The second section of the article is devoted to the exchange of experience and the results of the university becoming the center of social development in the regional innovation ecosystem of social assistance. An important aspect of this part is a positive result in several key areas: Globalization - mobility and increased competition between universities in China, South Korea, Japan, Poland, Germany, France, Lithuania, Belarus, Ukraine, Kazakhstan and the United States; Multidisciplinary and Interdisciplinary - the integration of science, technology and design, teams from different faculties and universities; and Corporatization - specialized institutes of applied research, and extension of stakeholders. The final section presents the Transformation Program of the Krasnoyarsk State Pedagogical University at the University Center for Social Development of the Krasnoyarsk Territory for current and future operations. The program includes both initiatives and ongoing projects. Today, many successful examples prove that the Center for Social Development in the field of social assistance of the Krasnoyarsk State Pedagogical University plays an important role in the development of the region. Conclusion. Krasnoyarsk State Pedagogical University really stands on the route to the social entrepreneurship development and influx of new technologies, introduction of innovative approaches, and becomes the center of social and project competencies of the Krasnoyarsk Territory, one of the leading drivers of social development and of social assistance of the region.

Honey is a sweet substance produced by bees, well appreciated in many places and its consumption has been increased either as raw material or as a food ingredient. Its use as food by the consumer, or even for exportation, implies safety inherent in its quality and processing control. Gamma radiation can be applied in food or ingredients for many objectives like pathogens microorganisms’ reduction, disinfestations, and sterilization. The aim of this work was to verify some physicochemical modifications, as well as rheological evaluation of honey submitted to irradiation at 10 kGy. The physicochemical parameters analyzed were: moisture, HMF, free acidity, pH, sugars and ash. The rheological behavior was measured at different temperatures. The results indicated that few changes occurred; the rheological behavior was not impaired and did not present any significant physicochemical alteration.

Opis:
In Tropical Savannah flooded valley soils, very low infiltration rates often result in acidic conditions favourable to high concentrations of metallic ions, toxic for rice. Determination of the under-phreatic infiltration rate is important in drainage design to reclaim degraded soils. Several studies have addressed the mapping of the infiltration rate. Yet, its relationship with the toposequence of the valley is not clarified. This paper has investi- gated such a possibility, examining the case of the irrigated rice valley of Tiefora, Burkina Faso. Nine boreholes – from 1 to 5 m deep – were implemented from upstream to downstream. The Lefranc permeability test of the under-phreatic level in water- logged soils – used when the impervious layer is close to soil sur- face or absent – was conducted. First, a comparative regression was applied to the data, including all the parameters of the regression curves. In the case of dissimilarity of the infiltration processes, the comparison focused on the final permeability. The results show a permeability increase from upstream (0.10±0.10 cm h -1 ) to down- stream (greater than 20±10 cm h -1 in some places). Taking into account such a permeability increase in the subsurface drainage system design would result in implementation of more efficient and cost effective systems.

Opis:
Precise measurement of the inner structural strain of polymer bonded explosive (PBXs) granules during compression molding is highly desirable in order to investigate the inner stress distribution field and its underlying generation mechanism, with the aim of improving the stress distribution uniformity. In this contribution, TATB-based (1,3,5-triamino-2,4,6-trinitrobenzene) PBX granules were formulated and the stress-strain state of the PBX granules during the warm molding process was analyzed. Strain markers were implanted at different locations and the deformation characteristics and regularity of the embedded spherical strain markers were obtained by X-ray micro-tomography. Thus the local strain states at different locations could be obtained, and the local stress state could be deduced. The results showed that axisymmetric deformation occurred in all of the strain markers, where the flat strain ellipsoids were mainly compressed uni-axially. In the central region, the stress was mainly in an axial direction, and the shear force was small. Not only axial stresses, but also large shear stresses in the surrounding region of the cylindrical grains were present. The stress gradient in the central region was greater than that in the surrounding region. The stress was greater in the surrounding region because this region was squeezed by the mold. The maximum strain degree was 44.8% larger than the minimum strain degree. The local stress increment in each region was quantified. The stress increments of the three axes were in the range 14.2-19.5 MPa. This study examined the feasibility of evaluating the inner stress–strain state of PBX granules in a quantitative manner, which is significant in determining the inner strain and stress distribution in PBX granules during the molding process.

Opis:
This study describes ammonite taxa of the Perisphinctoidea in the Jurassic/Cretaceous boundary interval at Le Chouet (Drôme, France). Emphasis is placed on new and poorly known Himalayitidae, Neocomitidae and Olcostephanidae from the lower part of the Jacobi Zone auctorum. Significant results relate the introduction of Lopeziceras gen. nov., grouping himalayitid-like forms with two rows of tubercles, and Praedalmasiceras gen. nov., grouping the early Berriasian Dalmasiceras taxa. Study of the ontogenetic sequences of both genera show that they were derived from late Tithonian Himalayitidae. This supports the distinction between the subfamilies Himalayitinae and Dalmasiceratidae subfam. nov. Content, variation, dimorphism and vertical range of the Neocomitidae Berriasella, Pseudoneocomites, Elenaella and Delphinella are discussed. A conservative use of the Olcostephanidae Proniceras is followed herein.

The measurements were carried out using neutral aqueous solutions of the diethylenetriaminepentaacetic- acid-complexes with initial isotopes at 293 K and 77 K. It was shown that the $\text{}^{111}$Cd-diethylenetriaminepentaacetic-acid-complex in aqueous solutions at pH = 7.0 is characterised by the re-orientational correlation time of 7.7×10$\text{}^{-11}$ s and an electric field gradient V$\text{}_{zz}$=6.7(2)×10$\text{}^{21}$ V/m$\text{}^{2}$ with an asymmetry parameter η=0.75(5). A direct comparison of the electric quadrupole interaction parameters for diethylenetriaminepentaacetic- acid-complexes with $\text{}^{111}$In and $\text{}^{111m}$Cd confirmed the proposal about the fragmentation of the complexes caused by the after-effects of electron capture in $\text{}^{111}$In. An observed difference in the electric quadrupole interaction parameters obtained for the solutions with $\text{}^{111}$In and $\text{}^{111m}$Cd complexes reflects a process of a chemical rearrangement of the complex structure after the In decay into Cd

Opis:
This work proposes a methodology to analyze masonry historical structures (stone or brick). They are mainly characterized by their self-weight which is the dominant action that acts on them, such us churches, cathedrals, etc. The proposed methodology is based on the analysis of finite element models that simulate the real structure behaviour. Therefore, much more information can be obtained about the structure safety than applying the usual methodology (the graphical statics considering the limit analysis). Using the proposed methodology, the structure response can be determined applying some loads on the model and considering some support conditions that simulate foundation settlements. The effect of structural reinforcement, wear of some blocks, non linear properties of the materials, etc. can be also considered. The safety level of the studied structure is evaluated with the obtained analytical results.
W niniejszej pracy zaproponowano wykorzystanie metody elementów skończonych do analizy historycznych konstrukcji murowanych (kamienia lub cegły). Zasadniczą cechą tych konstrukcji jest ich ciężar własny, który stanowi w ich przypadku podstawowe obciążenie np.: kościoły, katedry itp. Zaproponowana metodologia jest oparta na analizie metodą elementów skończonych modeli, które symulują zachowanie rzeczywistej konstrukcji. Pozwala to na uzyskanie większej ilości informacji dotyczących bezpieczeństwa konstrukcji, niż przy użyciu zwykłych metod (statyka wykreślna z uwzględnieniem analizy stanów granicznych). Przy wykorzystaniu proponowanej metody, reakcja konstrukcji może być określona poprzez zwiększenie obciążenia na modelu i przebadanie warunków podparcia, które symulują osiadanie fundamentów. Efekt wzmocnienia konstrukcji, zużycie materiałów, ich nieliniowe właściwości, itp. mogą również zostać uwzględnione. Poziom bezpieczeństwa badanej konstrukcji jest oceniany na podstawie uzyskanych wyników analiz.

Opis:
The normal modes cannot be extracted even in the Pekeris waveguide when the source-receiver distance is very close. This paper introduces a normal mode extraction method based on a dedispersion transform (DDT) to solve this problem. The method presented here takes advantage of DDT, which is based on the waveguide invariant such that the dispersion associated with all of the normal modes is removed at the same time. After performing DDT on a signal received in the Pekeris waveguide, the waveform of resulting normal modes is very close to the source signal, each with different position and amplitude. Each normal mode can be extracted by determining its position and amplitude parameters by applying particle swarm optimization (PSO). The waveform of the extracted normal mode is simply the waveform of the source signal; the real waveform of the received normal mode can then be recovered by applying dispersion compensation to the source signal. The method presented needs only one receiver and is verified with experimental data.

Opis:
During the Late Pleistocene, several possibly endemic cingulate species, known mostly from isolated osteoderms, carapace fragments, and caudal tubes, coexisted in the Brazilian Intertropical Region. Here, we describe the osteoderm microstructure of Pachyarmatherium brasiliense, as well as the glyptodonts Panochthus greslebini, Panochthus jaguaribensis and Glyptotherium sp., in order to provide additional species-diagnostic characters and shed light on their evolutionary relationships. Pachyarmatherium brasiliense lacks several derived features shared by glyptodonts and pampatheres, such as extensive bone remodeling, fibers arranged in large bundles, and relatively poorly developed layers of compact bone, thus supporting its exclusion from glyptodonts as suggested by a recent cladistic study. The osteoderm histology of P. greslebini resembles that of other species of Panochthus (e.g., Panochthus frenzelianus). By contrast, the presence of relatively thick layers of compact bone, the configuration and size of resorption areas, the absence of randomly oriented lateral fiber bundles, and the absence of an intermediary region between the compact and trabecular bone potentially support the exclusion of Panochthus jaguaribensis from the genus. Finally, osteoderms of the Brazilian specimens of Glyptodontinae share histological features with Glyptotherium floridanus, rather than Glyptodon, thus reinforcing their assignment to Glyptotherium. These results highlight the relevance of histological osteoderm characters in cingulate systematics, ands call for further and more comprehensive studies.

Opis:
Finger millet is a staple food crop of many communities in Africa. The crop is highly nutritious and has incredible grain storage quality. Limited research investment in finger millet in the past has resulted in poor yields and there are currently no commercial hybrids. We investigated the response of different finger millet genotypes (Okhale-1, Gulu-E, KACCIMMI-72, IE 2872, IE 4115 and U-15) to the application of a plant growth regulator hormone (Ethrel). Six elite Kenyan finger millet varieties with contrasting agronomic traits were crossed in a 6 x 6 diallel pattern. To enhance male sterility across female parents, we subjected the plants to Ethrel at concentrations of 1,500ppm, 1,750ppm and 2,000ppm against a 0ppm check. Dwarfing of sprayed plants that resulted in less lodging and ultimately higher yields were observed among plants sprayed with Ethrel at different concentrations. Ethrel application at 2,000ppm had the most dwarfing effect on plants while spraying plants with 1,500ppm of Ethrel resulted in increased grain weight. Although our results demonstrate overall positive effect of Ethrel on finger millet production, the optimum concentrations for more efficient hybridization will still need to be determined.

Background. Nowadays the importance of lifestyles in the prevention of type 2 diabetes and the metabolic syndrome has been largely accertained. Objective. The purpose of our work is to implement programs that promote a nutritional culture in adolescents and young adults of the La Sabana University. Methods. The methodology entailed, after the corresponding informed consent, taking measures of the triceps and supraescapular skinfolds, waist circumference, body mass index (BMI), lean mass, and fat mass. Fasting blood samples were also taken to quantify cholesterol, triglycerides, high density lipoprotein (HDL) and low density lipoprotein (LDL). Results. The results obtained show that of the 165 students, 10.3% were underweight, 13.93% were overweight and 0.6% were obese. With regards to gender, 4.8% of the men and 9% of the women were overweight, 3% of the men and 7.2% of the women were underweight, and 0.6% of the women were obese. The blood chemistry showed that 30% had hypercholesterolemia, 18% hypertriglyceridemia, 17% reported low HDL levels and 67% reported high LDL levels. Of all the cases studied, 40% are at risk of a metabolic syndrome. 60% claimed not to practice any physical activity - especially women who reported 44.70%. Conclusions. These findings have allowed us at the institution to implement a culture of healthy habits. The have also allowed us to identify students with risk factors for type 2 diabetes and metabolic syndrome. This is why the cardio- metabolic monitoring and control based on healthy eating and physical activity are important.

The Radiation Technology Center from IPEN-CNEN/SP, Brazil, developed a revolutionary design and national technology, a small-sized continuous run and multipurpose industrial gamma irradiator, to be used as a demonstration facility for manufacturers and contract service companies, which need economical and logistical in-house irradiation system alternatives. Also, to be useful for supporting the local scientific community on development of products and process using gamma radiation, assisting the traditional and potential users on process validation, training and qualification of operators and radioprotection officers. The developed technology for this facility consists of a continuous tote box transport system, comprising a single concrete vault, where the automated transport system of products inside and outside of the irradiator utilizes a rotating door, integrated with the shielding, avoiding the traditional maze configuration. Covering 76 m2 of floor area, the irradiator design is a product overlap sources and the maximum capacity of cobalt-60 wet sources is 37 PBq. The performed qualification program of this multipurpose irradiator was based on AAMI/ISO 11137 standard, which recommends the inclusion of the following elements: installation and process qualification. The initial load of the multipurpose irradiator was 3.4 PBq with 13 cobalt-60 sources model C-188, supplied by MDS Nordion – Canada. For irradiator dose optimization, the source distribution was done using the software Cadgamma developed by IPEN-CNEN/SP. The polymethylmetacrylate (PMMA) dosimeter system, certified by the International Dose Assurance Service (IDAS) of the International Atomic Energy Agency (IAEA) was used for irradiator dose mapping. The economic analysis, performance concerning with dose uniformity and cobalt-60 utilization efficiency were calculated and compared with other commercial gamma irradiators available on the market.

There are few reports in literature about the selectivity of postemergence application of herbicides for the control of eudicotyledon weeds (broadleaf) in chickpea. For this reason, the aim of this study was to investigate the selectivity of diphenyl-ether herbicides in chickpea influenced by the herbicides and application rates. A field experiment was conducted from February to June 2017 in Urutaí, state of Goiás, Brazil. Cultivar BRS Aleppo was used in the experiment. The experiment was set up in a randomized block design with 2 × 3 + 1 factorial arrangement and three replications. The first factor was herbicides (fomesafen and lactofen) with the second factor being herbicide rate (50, 75, and 100% of referenced rate) plus an untreated check as a comparison. The applied rates of herbicides were 250 and 180 g ⋅ ha–1 of fomesafen and lactofen, respectively. The selectivity of herbicides was evaluated according to agronomic characteristics (plant population, height, dry matter, number of pods per plant and 100-grain weight) and yields. Both herbicides, regardless of dosage, were selective in chickpea cultivation, even exhibiting leaf necrosis symptoms with visible injuries below 20% with no effect on yield.

Opis:
Concerning the contribution of fungi to soil carbon sequestration, various methods have been used to extract ergosterol from soil samples. This study aims to explore the extraction ability and applicability of commonly used methods to extract ergosterol from two contrasting soils. An agricultural soil (chernozem) and a forest soil (podzol) were extracted with different types of cell lysis such as alkaline, glass bead, and ultrasonication methods in association with simple shaking. The ergosterol concentration was measured by high pressure liquid chromatography. Regardless of the method applied, ergosterol yield was higher in podzol than in chernozem. Alkaline extraction resulted in the highest ergosterol concentrations for both soils and miniaturized glass bead extraction produced comparable results in the case of chernozem. In terms of applicability, the non-alkaline methods were simpler to conduct and less demanding of labour, chemical use and glassware and more flexible in terms of the equipment used for mechanical disruption. Despite the limit of the two soil types in the present study, only the simple shaking method was revealed to be dependent on soil type. Based on our results, we recommend the miniaturized glass bead method for agricultural soils, low in organic matter for high throughput. However, not all of the methods described allow for the proper separation of coextracted organic substances from organic-rich soil.

Opis:
Root-knot nematodes, genus Meloidogyne, are among the most plant damaging pathogens worldwide. The action of natural products against plant pathogens has been investigated to assess their effectiveness in the control of diseases. Thus, the present study aimed to evaluate the phytochemistry potential of the Ficus species for the control of Meloidogyne javanica. In vitro inhibitory activity assays were performed with crude ethanolic extracts of leaves and branches from 10 Ficus species. Among these, Ficus carica extracts exhibited strong paralysis activity against second stage juveniles (J2) (EC50 = 134.90 μg ∙ ml–1 ), after 72 hours. In addition, high efficacy was observed in egg-hatching inhibition at different embryonic stages. Microscopy analysis revealed severe morphological alterations in the nematode tissues at the J2 stage, as well as immotility of juveniles released from eggs in the presence of F. carica extracts. The efficacy of the treatments for the other species was very low. These differences were supported by the variation in the compound classes, mainly for alkaloids and metabolite profiles by Gas Chromatography/Mass Spectrometry (GC/MS) when F. carica was compared with the other species. The results indicated that F. carica is a promising source for the isolation and identification of molecules capable of acting in the control of M. javanica.

Opis:
The Albergaria-a-Velha Unit is one of several tectonostratigraphic out-of-sequence units of the metamorphic belt associated with the Porto-Tomar shear zone (Ossa-Morena Zone, W Portugal). It is composed of considerably deformed - very low grade - metasediments, namely shales, siltstones and rare fine sandstones. In this work we present new sedimentological and biostratigraphical data that suggest the Albergaria-a-Velha Unit was deposited from the (?)early Frasnian to the Serpukhovian in a distal marine environment, where turbiditic and basinal sedimentation prevailed. Palynofacies analysis and lithological data point to a gradual increase of terrestrial input, suggesting a prograding system. Detrital framework data is indicative of a stable cratonic sediment source area composed of low grade metamorphic rocks. The timing of the onset of the Porto-Tomar shear zone activity and consequently its influence on the sedimentation of this unit is discussed. Organic petrology and geochemistry data indicate that the Albergaria-a-Velha Unit is within the dry gas window in terms of hydrocarbon generation ranges.
