Understanding vascular Ehlers-Danlos syndrome
Authors: Boheler Kenneth Richard
Published: November 2018

The discovery of experimentally derived induced pluripotent stem cells (iPSCs) has fostered prospects of patient-specific cell replacement therapies, novel toxicology and drug screening assays, and informative cell models for understanding disease pathogenesis. The latter is particularly
valuable to the study of human syndromes caused by gene defects where animal models are lacking or inadequately mimic the human condition. One such vascular variant is Ehlers-Danlos Syndrome (EDS), a heritable disease of connective tissues involving collagen types COL5A, COL3A, tenascin-X,
and to a lesser extent COL1A, lysyl hydroxlase and ADAM metallopeptidase. Among the six major types, the vascular form of EDS (vEDS) is the most severe. It results principally from mutations in the collagen III, alpha 1 (COL3A1) gene and is thought to cause aberrant collagen fibrillogenesis.
These mutations contribute to catastrophic ruptures of large arteries, strokes, pregnancy-related mortalities, and pre-mature death among young adults. The presentation of this disease is heterogeneous, even among patients with the same gene mutation, and it remains unclear why some individuals
exhibit severe phenotypes while others do not. In mouse models, COL3A1 deficiency mostly produces a weak disease variant without vascular ruptures, while a spontaneous COL3A1 mutation that leads to vascular defects lacks important disease features found in humans. Currently, there are no adequate
therapeutic treatments. To determine how COL3A1 mutations lead to vEDS, we propose to examine and exploit a human cell model of this disease using iPSC lines derived from fibroblasts obtained from two probands. We will correct the Col3A1 gene mutations with TALENs to ensure against phenotypic
iPSC variability and determine the principal source of COL3A1 secretion from iPSC-derived vascular progeny. We will examine basic growth characteristics and functional properties of these cells as well as determine the effects of doxycycline on collagen and matrix metalloproteinase synthesis
(RNA and protein), stability or activity. By establishing high quality, experimentally confirmed iPSC vascular progeny, this study should lead directly to the development of reliable human tissue models of vEDS suitable for examining the effects of COL3A1 mutations on vasculogenesis and vascular
integrity as well as establish a reliable system to test for possible therapeutic (pharmacological or regenerative) interventions.

PRO–CF–MED, Clinical Proof of concept for a RNA–targeting Oligonucleotide for a Cystic fibrosis–F508del MEDication, Horizon2020
Authors: Lamontagne Nicolas
Published: November 2018

Cystic fibrosis (CF) is a progressive life–shortening disease caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene leading to a dysfunctional CFTR protein. The disease affects over 70,000 patients worldwide and while many mutations are known,
the F508del mutation affects 90% of all patients. The absence of CFTR in the plasma membrane leads to a dramatic decrease in chloride efflux, resulting in viscous mucus that causes severe symptoms in vital organs like the lungs and intestines. For CF patients that suffer from the life threatening
F508del mutation only palliative treatment exist. PRO–CF–MED addresses the specific challenge of this call by introducing the first disease modifying medication for the treatment of the CF patients with F508del mutation. The PRO–CF–MED project has been designed
to assess the potential clinical efficacy of QR–010, an innovative disease modifying oligonucleotide–based treatment for F508del patients. Partners within PRO–CF–MED have generated very promising preclinical evidence for QR–010 which allows for further clinical
assessment of QR–010 in clinical trials. PRO–CF–MED will enable the fast translation of QR–010 towards clinical practice and market authorisation. PRO–CF–MED has the potential to transform this life–threatening condition into a manageable one.
Migration, Mortality and Medicalisation: investigating the long-run epidemiological consequences of urbanisation 1600 - 1945
Authors: Smith Richard , Davenport Romola
Published: November 2018

Today life expectancy is generally higher in urban than rural populations, but early modern towns and cities were demographic sinks with extraordinarily high mortality, especially among the young and migrants who were essential for city growth. The breakthrough to urban natural increase
that occurred in the late eighteenth century and the eradication of the urban penalty in the 1930s mark the endpoints of major epidemiological transitions. We seek to investigate how and when cities transformed from urban graveyards into promoters of health between 1600 and 1945. We hypothesize
that the processes of endemicisation and exogenous disease variation were key to the evolution of both urban and non-urban mortality regimes, especially with respect to: infectious disease among the young, maternal health, adult migrants and their health/immunological status. This project
brings together evidence from institutions (including medical and welfare), registrations of deaths and cause-of-death statistics to provide a continuous overview of the long-run pattern of urban life chances in Britain. The experiences of other European and North American populations will
also be employed to elucidate the extent to which towns were drivers of epidemiological change during the first demographic transition, and the differing roles of health and welfare provision, industrialisation and migration in these processes.
Application of 3D printing in cardiovascular intervention
Authors: Lee Alex Pui-Wai
Published: November 2018

This study aims to define the clinical history and significance of mitral leaflet (ML) adaptation in ischemic mitral regurgitation (IMR). Mitral regurgitation (MR) (leaking of left heart valve) frequently complicates myocardial infarction (MI) (heart attack) and is associated with doubled
mortality and morbidity. Unfortunately, its mechanism is incompletely understood and treatment options are often limited and ineffective. It has been widely accepted that IMR is purely "functional", because the ML appear grossly normal, but only tethered by left ventricular and annular dilatation,
preventing adequate closure. Therefore, contemporary treatment of IMR focus mainly on annular and ventricular remodeling. However, the ML tissues are metabolically active capable of cell activation and matrix proteins production. Recent animal studies has suggested that the ML actively adapt
to mechanical stretch by increasing its surface area and thickness, casting doubt on functional IMR being purely "functional". In clinical settings, our understanding of the natural history of ML adaptation is very limited. Its incidence, timing, clinical significance, and interactions with
annulus and ventricular remodeling remain undefined. The clinical data has been lacking because imaging techniques were previously unable to assess leaflet surface area in vivo. Recent advance in real-time 3-dimensional echocardiography (RT3DE) has enabled us to assess mitral valve 3D geometry
non-invasively, providing a new way to study ML adaptation in clinical settings. We hypothesize that ML adaptation does occur in IMR after MI, attempting to increase in size to compensate for the tethering caused by ventricular and annular dilatation. To test this hypothesis, we will prospectively
study 2 groups of patients presenting with MI, one group complicated with IMR, one group without. We will follow them up with serial RT3DE from the acute phase of MI to the chronic phase for 1 year. The 3D geometry of ML, annulus and left ventricle will be analyzed using a novel software developed
and validated collaboratively by the Chinese University of Hong Kong and the University of Hong Kong. We will (1) compare the prospective changes of ML geometry between the 2 groups, (2) define the long-term natural history of ML adaptation, (3) explore how it is related to pathogenesis of
IMR, and (4) identify potential factor(s) that affect ML adaptation. We believe the results of this project will significantly increase our knowledge on mitral valve adaptation in IMR. Understanding and potentially influencing the adaptive mechanisms will contribute to new, much needed treatment
for IMR, a common and often devastating disorder. Researcher ID (E-9217-2013) : http://www.researcherid.com/rid/E-9217-2013
The development of an artificial protein for periodontal application
Authors: Inoue Takashi
Published: November 2018

Most artificial implants in medicine are purely mechanical. They do not harness the natural biology, merely co-exist alongside it. This is no different in dentistry where false teeth tend not to interact with the biology of the mouth. Inoue and his team are developing bio-hybrid dental
implants that are capable integrating themselves into the jawbone. The new implant will be more stable and long-lasting as well as being able to replicate the function and feel of natural teeth. They also have the crucial ability of being able to adapt to the restructuring in the jawbone that
occurs as children age. Children's adult teeth must be able to move as the jawbone grows and adapt to new positions. Inoue summarises the issues surrounding dental implants: 'At present, dental implants are connected directly to the alveolar bone, with no mediation by periodontal tissues.
It must be remembered, however, that these tissues play an important role not only in tooth support, but also in maintaining various physiological functions, including sensation and the tooth movement that usually accompanies bone remodelling.' The implant designed by Inoue and his team
is based on a standard titanium core, but is enhanced in several different ways. The implant is coated in hydroxyapatite (HA), a mineral found in high concentrations in dentin and that is known to help stimulate bone growth. This basic implant is transplanted with a mixture of periodontal
tissue extracted from another tooth. Together, HA and the periodontal tissue work together to promote true ossointegraton and the creation of a bio-hybrid implant. In experiments with young mice, the implant has been shown to integrate fully in the jaw and move as and when necessary during
development, just like a normal tooth. In addition to these benefits, the novel hybrid actually maintains the ability of the tooth to sense noxious stimuli – something no current implant can do.
Investigating whether vitamin B12 and folic acid supplementation slows cognitive decline
Authors: Kwok Timothy Chi-yui
Published: November 2018

Given the increase in average lifespans in countries around the world, diseases that afflict the elderly are a major focus for scientists. Uppermost among these is dementia, a broad term which includes many types of cognitive decline from mild impairment to severe conditions such as
Alzheimer's disease. We lose brain volume and function as we age, and it is this atrophy of different parts of the brain that leads to loss of cognitive function. Although atrophy takes many different forms and thus results in a range of conditions, there are commonalities between each that
might be targets for treatment. One area of research is the possibility of using large doses of B vitamins to lower levels of the amino acid homocysteine, which has been linked to many conditions including cardiovascular disease and dementia. This is the focus of Professor Timothy Kwok's
ongoing research at the Chinese University of Hong Kong. Kwok is also a practising consultant geriatrician at the Prince of Wales Hospital in Hong Kong and has been inspired to pursue this field of inquiry by the need for simple and inexpensive treatments which could be made available to large
numbers of elderly patients. He says: 'A trial at the University of Oxford showed that lowering homocysteine levels led to a significant reduction in the rate of brain atrophy. However, many questions remain unanswered and our current two-year trial will hopefully give further insights into
the benefits or otherwise of vitamin B supplementation. If a causative link can be found between vitamin B supplementation and a slower rate of cognitive decline, this would be an inexpensive and safe way of treating people at the early stage of disease. In addition, these vitamins could
potentially be given as a preventative treatment in older people who are not yet showing signs of cognitive impairment. As Kwok says: 'Dementia is a major cause of dependency in old age and has a big impact on the people affected, their families and scarce medical resources. If supplementation
could prevent dementia in people with early symptoms, this simple intervention could make a huge difference to the quality of life of elderly people and reduce the burden of dementia on national health services.'
The Emergent Aspect Dualism View of Quantum Physics: A New Ontology to Resolve the Complementarity Conundrum
Authors: Tyler Christopher W.
Published: November 2018

To resolve the conceptual problem of the conflict between quantal and relativistic formulations of Quantum Physics, this paper proposes a new conceptual ontology, Emergent Aspect Dualism, that reconceptualizes the foundations of the field. Emergent Aspect Dualism is a philosophical approach that starts from the assumption is that the primary “material” of the universe is energy, which can be manifested as kinetic energy, potential energy or matter. The flow of such energy throughout the universe is described by the continuous Schrödinger Equation, but in order to account for the hierarchy of levels of organization reality, we need to invoke the concept of emergence, under which the operative principles of each level of organization of this energy are entirely dissociated from those of the levels below it, and, crucially, the functional emergence of the properties of the conscious mind that are dualistically dissociated from the underlying biochemical principles of brain organization. Rather than assigning probabilities to the quantal realm, Emergent Aspect Dualism treats probability as an operational concept that can be held only by a conscious mind, a philosophical category that incorporates the properties of a) the superposition of states and b) the collapse of this superposition once an observation is made. 
Microwave Disinfection of Biohazardous Carcasses
Authors: Zimmermann Klaus , Katschnig Roland
Published: November 2018

A Medister microwave device specifically developed for thermal disinfection of infectious waste was assessed concerning its efficacy for the disinfection of biohazard us animal carcasses. Employment of animals for the experiments was avoided by simulation of carcasses with deep frozen nutrient agar contaminated with bacillus subtilis spores. At a disinfection time of 45 minutes, the reduction rate of the spores was 7.90-8.58 decimal power levels. Controlled microwave disinfection is thus a valuable alternative tool for the treatment of contaminated carcasses.

De la estabilidad al Pacto: análisis del cambio en el sistema educativo mexicano
Authors: Gómez Zamarripa Erika Yazmin , Navarro Arredondo Alejandro
Published: November 2018

Este artículo tiene por objeto examinar los factores que han hecho posible el surgimiento de algunas reformas educativas en México. Comúnmente se asume que para su aprobación se requiere en mayor medida del consenso de diversos actores con poder, lo que ha centrado gran parte de los estudios en la toma de decisión ejecutiva o legislativa, segregando el análisis de los elementos contextuales que pueden influir en un momento determinado. Por este motivo, el texto se centra en la comprensión de la dinámica política en los casos en los que el cambio ha ocurrido. En particular, se explica por qué el sistema educativo mexicano ha mostrado estabilidad en sus políticas educativas durante largos periodos de tiempo, y por qué se han presentado oportunidades de reformas que trastocan varias dimensiones del sistema educativo. Para entender estas dinámicas se hará uso del marco de análisis del institucionalismo comparado y se examinarán las configuraciones causales de actores, ideas, intereses e instituciones que conducen al éxito o al fracaso de las reformas educativas.
Composición química de ejemplares de la almeja taquilla Mulinia edulis de bancos naturales del norte y sur de Chile
Authors: Abarca Alejandro , Toledo Pedro , Oliva Doris
Published: November 2018

Chemical composition, morphometry and meat yield of Mulinia edulis, were analyzed for two size groups and two locations. The clams were taken from natural beds, one located in the north (Peñuelas; 29°55´S) and the second in the south (Putemún; 42°25´S) of Chile. The first size group corresponds to legal catch size (>5.5 cm) and the second to ‘baby clams’ (<4 cm). The standardized AOAC methodology was used to determine the proximal values. Results show that M. edulis is a species with high water content in its tissues (>80%), high protein value (>11%) and low fat content (<2%). Proteins and total lipids were significantly higher in Peñuelas than Putemún. Furthermore, the water content (humidity) was higher in Putemún than in Peñuelas, and in baby clams than in large clams. Meat yield was higher in the Peñuelas clams (>20%) than those of Putemún (<20%). Finally, the clam M. edulis, independent of the origin and size, is a healthy food due to its low lipid content, but small clams (= baby clams) have a higher meat yield.

Published: November 2018

Mustelus lunulatus is the most important shark demersal species in the landings of the Ecuadorian artisanal fishery, this study was carried out to expand the knowledge about size, sex, type of growth (isometric or allometric) and reproductive aspects in males of the species. Biological traits of the sicklefin smooth-hound shark, M. lunulatus, caught in the Pacific coast of Ecuador were assessed by examining 199 individuals ranging from 41.2 to 135.0 cm in total length (TL). The means TL did not show significant differences between sexes. The sex ratio was not different from 1:1 and the weightlength relationship did not showed significant differences between males and females. Both sexes have a growth of isometric type (b males= 3.05 and b females= 3.15). Total length at sexual maturity (TL50) of male M. lunulatus, calculated from the clasper condition, was estimated to be 97.2 cm. The present study provides new information regarding the biology of M. lunulatus in Ecuadorian waters.
Redescripción de Percnon pascuensis (Brachyura, Grapsoidea, Percnidae) de Rapa Nui
Authors: Guzmán Guillermo L.
Published: November 2018

Percnon pascuensis is redescribed based on adult specimens collected in Easter Island (today Rapa-Nui). The gonopod (first two pair of pleopod of males) structure is described by first time and compare with the other species of the genus. The analysis conclude that P. pascuensis is closely to P. sinensis based on the gonopods morphology. P. sinensis is distributed to China Sea. Earlier papers claim that P. pascuensis is closely related with P. planissimum, a widely distributed species, but both species are different morphology of the gonopods. P. pascuensis is a valid species seemingly endemic of the Easter Island.

Mídias como expansão dos códigos culturais: a história da cultura segundo McLuhan
Authors: Machado Irene
Published: November 2018

Sem mediação tecnológica talvez não houvesse mudanças no modo de pensar. Essa é uma das teses que McLuhan examina em seus estudos sobre as transformações que a tecnologia dos meios de comunicação introduziram na cultura. Enquanto uns acreditavam que vincular o pensamento às ferramentas tecnológicas poderia ser puro delírio, outros conjecturavam: "E se McLuhan estivesse certo?'. Os quarenta anos que nos separam dessas inquirições talvez nos dêem aval para arriscar algumas hipóteses. Não para chegar a um veredicto, mas para assuntar a marcha de acontecimentos que criaram uma história: a história das mediações que, através de códigos culturais, subverteram os modos de pensar e de perceber o mundo. Tal é a história secreta da humanidade que McLuhan contou àqueles que, desde a invenção de Gutenberg, desfrutam de dispositivos cognitivos agenciados pela mente da cultura. Um pouco sobre dela falaremos nesse artigo.
O cinema e outras artes de Harold Pinter

O romance The Comfort of Strangers, de lan McEwan, publicado em 1982 o ponto de partida do roteiro cinematográfico escrito por Harold Pinter para o filme que leva o mesmo titulo dirigido por Paul Schrader no ano seguinte. Uma análise comparativa dos três fornecerá um exemplo consistente de como roteiros e adaptações de obras literárias para o cinema, ao não se limitarem a meramente tentar reproduzir o original, podem até melhorá-las através do uso competente e adequado de recursos cinematográficos. O resultado é uma autêntica recriação, que pode ainda envolver o uso de outros modos de expressão artística, tais como pintura e música.

Published: November 2018

One of the important processes of cocoa plants growing is pruning. It aims to eliminate sick, broken, or the appearance of water buds disturbing the cacao production. The period of pruning is varios. The various periods of pruning lead to leave wide waste of leaves, stems, and twigs. Yet the waste would not been used to other activities, only a small portion of the waste used as natural fuel (stems and twigs) and cocoa leaves waste as animal feed. Phytochemicals naturally present in every part of plants range from leaves, stem bark, fruits to roots. Secondary metabolites are natural products from plants which include alkaloid, flavonoid, steroid, terpenoid, sapponin compounds, etc. This study performed some phytochemical characterisations. It have confirmed that cacoa leaves consist some of bioactives compounds which are potential for furhter activities in pharmaceutical disease.

A partir del análisis crítico de diversas fuentes documentales, en especial sus actas de funcionamiento, el presente artículo analiza la actuación del Consejo de Rectores y el Consejo de Rectores de Universidades Nacionales, ámbitos de coordinación universitaria cuya actividad transcurre en el contexto de las dos últimas dictaduras militares en la Argentina. Aborda la problemática de la coordinación universitaria en períodos de autonomía restringida, procurando entender sus condiciones generales de funcionamiento, diferencias de contexto, como así también las continuidades y rupturas entre ambos. La ruta de las actas de funcionamiento nos permite reconstruir la agenda de trabajo, atribuciones normativas, prioridades, funcionalidad con los regímenes gobernantes, todo ello en un marco general de indagación sobre el papel desplegado por los rectores y sus respectivos consejos en la política universitaria del período.
Militancia Peronista para la liberación y su “alternativa” para el peronismo revolucionario. El debate con Montoneros y Juventud Peronista, 1973
Authors: Stavale Mariela
Published: November 2018

El presente artículo forma parte de una investigación más amplia, que reconstruye la experiencia editorial y militante de las revistas Militancia Peronista para la Liberación (MPL) y su continuación en De Frente, con las bases peronistas (DF) publicadas entre 1973-1974. Aquí, hacemos pie en la revista MPL y nos concentramos en el 1973, analizando las coyunturas conflictivas que hicieron que el peronismo revolucionario entre en crisis. En este escenario, el grupo político que surgió en torno a MPL atravesó un proceso de transformación de su identidad peronista que, a la vez, trastocó las apuestas políticas del grupo, dentro y fuera de la Tendencia Revolucionaria Peronista (TRP). Para dar cuente de este proceso, reponemos el debate entre el grupo MPL y Montoneros-Juventud Peronista (JP), por ser hegemónicas dentro de la TRP. Haremos énfasis en el análisis de El Descamisado, prensa orgánica de Montoneros-JP, porque expresó las posiciones públicas de la organización.

El Fair play, es uno de los contenidos importantes en el deporte escolar, ya que los centros educativos se enfocan ante todo en la formación integral de los niños y adolescentes, construyendo de esta manera una sociedad consecuente con los valores y derechos humanos. El objetivo del estudio es analizar el razonamiento moral de los/as escolares de tercer año medio, sobre la socialización tras una derrota deportiva, por medio de un dilema hipotético. La investigación respondió a una metodología cualitativa, en la que participaron 16 estudiantes de tercer año medio (10 hombres y 6 mujeres), con edades comprendidas entre los 16 y 17 años, pertenecientes a un colegio científico-humanista de la comuna de Quilpué, Chile. Los resultados indican seis dimensiones, que han sido percibidas por el alumnado como importantes para una manifestación de fair play ante la derrota deportiva y dos elementos que han de dificultar este objetivo. Se puede concluir que la educación valórica, la reflexión sobre la derrota y la inclusión de espacios de socialización entre los participantes de un encuentro competitivo, son factores identificados como relevantes para el fair play.
Soil – Plant Relations on Sandy Grassland in the Middle Vistula River Valley
Authors: Harasimiuk Andrzej , Cyrczak Magdalena
Published: November 2018

The paper is on environmental condition of sandy grassland on alluvial deposits. The soil and phytosociological study ware conducted south of Warsaw in middle Vistula river valley. Listing of vascular plants and shallow soil sampling were made in order to answer the question of plant and soil relationship. Standard chemical determination directed on trophism were done in plant and soil material. The spatial distribution of chemical parameters of plants and soils is related to local microrelief and distance of Vistula river. The plants dominating the study prefer less fertile habitats. The soil is being enriched by water from the Vistula river. High carbon content is correlated with the presence of the Salix arenaria. The greater the share of vegetation not belonging to the grass family, the greater the carbon content. Potassium and phosphorus looks like to be the less plant-dependent elements. Its documents an initial stage of development of the Vistula river valley environment.
Orographic Barrier of the Great Himalayas
Authors: Zgorzelski Marek
Published: November 2018

The entire geographical literature, starting with school textbooks, presents the Himalayas as a classical model of an impermeable orographic barrier, halting the masses of monsoon air and causing aridity of the Tibetan landscapes. Despite of that, however, the author, during his trips to Western and, particularly, to Central Tibet, organised exactly during the summer monsoon, always found the southern regions of these provinces flooded to a large extent with water. It is also puzzling that catastrophic floods occurring in China (connected with the high water in rivers originating in Tibet) are correlated in time with the period of the summer monsoon in the Himalayas.
Inferring Changes in Dynamic Groundwater Storage from Recession Curve Analysis of Discharge Data
Authors: Somorowska Urszula
Published: November 2018

Groundwater storage is an important element of terrestrial water storage. It influences the baseflow component of the river discharge which constitutes the majority of the outflow of Polish rivers. An evaluation of changes in the dynamic groundwater storage from point measurements of groundwater levels is usually a difficult task as groundwater data are scarce in time and space. Alternative approach involves recession curve analysis of discharge data. This study describes an approach to estimate the long-term changes in dynamic groundwater storage from daily discharges on a basin scale. Recession curve analysis is applied for identification of groundwater system functioning through derivation of master recession curve. The Master Recession Curve Tool developed by Lamb is used for automate analysis. Then results are coupled with a concept of nonlinear reservoir expressing discharge-storage relationship. As a result the volume of the groundwater storage and its temporal changes are derived on a yearly base, as a difference between highest values of storage during spring season and lowest values appearing in late summer or early autumn. The results show high annual variability of dynamic groundwater storage. The approach is presented on the example of lowland basin situated in central Poland, on the Mazovian Lowland (N 52°14’ – N 52°14’ and E 11°10’ – E 11°10’).
Inertia of the Catchment Systems Within the Polish Lowlands
Authors: Pokojski Wojciech
Published: November 2018

The paper presents a method for assessing the hydrological inertia of the river catchment areas using the autocorrelation function. The method presented can be used as the criterion for the determination of the degree of hazard to the river basins from the potential hydrological droughts. The basins with high inertia are less susceptible to the shortages of supply and are less threatened by the occurrence of hydrological droughts.
The Development of the Utilisation of Water Power in Poland
Authors: Mikulski Zdzisław
Published: November 2018

First hydroelectric power stations in Poland were built in 19th century, mostly in the region of Podhale (Carpathian tributaries of the Vistula River) and in the Old Polish Industrial District (for the needs of the iron and steel industry) from the initiative of Stanisław Staszic. They were used in mills and saw mills, for home lighting in settlements, etc. After World War I two medium size hydroelectric power stations were constructed in Pomerania (Gródek and Żar) and the construction of a dam (at that time the largest in Europe) was started in Rożnów on the Dunajec River (50 MW); the hydroelectric power station was opened as late as 1941. A small growth in this field took place in the 1950s and 1960s, and in the late 1960s / early 1970s large hydroelectric power stations were built (Solina, Włocławek, Żydowo). The largest growth occurred in the late 1980s and early 1990s, when the two giant peak-load, pumped-storage power stations were put into operation (Porąbka-Żar: 500 MW and Żarnowiec: 680 MW), reaching the total power of 2000 MW. The most recent two large installations are: Czorsztyn-Niedzica (92 MW, 1997) and the modernisation of Solina (200 MW, 2003).
The Problem of Cartographic Representation in Relation To the Polish Cultural Landscape
Authors: Opach Tomasz
Published: November 2018

The problem of representing the Polish cultural landscape consists of two components. The first component is the choice of content. Wishing to define the breadth of the content of a cultural landscape map, one needs to remember that it is composed of two facets. The first facet, the material result of human activity, is easily discernable in the field and easily illustrated on a map. Elements included in this facet are: sacred and secular historical structures, the spatial layout of cities, archeological sites etc. The second facet of cultural landscape needs to be considered in immaterial terms. It is difficult to illustrate on a map, because its elements do not lend themselves to being topographically situated. One could mention, for example, religions, customs and traditions, a common historical past etc. Most often, one can only indirectly speculate about this facet of the cultural landscape, on the basis of the material characteristics of the cultural landscape.

The second problem related to presenting cultural landscape on a map is the choice of graphic form for the map. The problem is to a large extent tied to difficulties stemming from the necessity of maintaining semantic correctness (the relation between “symbol” and “object”). In practice, during the graphic editing of a map representing the cultural landscape, one should remember to: a) choose a scale suitable for the representation, upon which depend the degree of detail and the generalization of the content; b) correctly depict the variation boundaries, taking into account sharp and fuzzy boundaries; c) make a well-designed symbol key.
Examples of Object-Oriented Classification Performed on High-Resolution Satellite Images
Authors: Lewiński Stanisław , Zaremski Karol
Published: November 2018

Information about the types of land cover and its use is obtained by the visual interpretation of the color composite of satellite images or by the use of automatic classification algorithms. For obvious reasons, the automatic classification methods make it possible to obtain information quicker and much faster than the traditional interpretation method.

The commonly used automatic methods of satellite image classification, based on supervised or unsupervised classification algorithms, are the most accurate when used with low resolution images. In the case of images with 1-meter-sized pixels, showing a diversity of land cover forms, it is not possible to obtain satisfactory results.

New classification techniques, based on object-oriented classification algorithms, have been developing for a couple of years now. In contrast to the traditional methods, the new operating procedure does not involve the classification of single pixels, but of entire objects, into which the content of the satellite image is divided. Aside from the spectral values of the pixels, the shape of the objects created by the pixels and the relationships between the objects, are also considered during the analysis. Similar to visual interpretation, variation in the texture of the image can also be taken into account in this case.

The aim of this article is to present the possibility of using high density satellite images in object-oriented classification. The classification presented is that of a high-rise built area in Wrocław and of bridges on the Vistula River in Warsaw.
