Possibilities of safe yield increase in the Wydrzany well field (Uznam Island, Poland) by surface water from a drainage system
Authors: Hoc Ryszard , Sadurski Andrzej , Wiśniowski Zenon
Published: January 2020

In parallel with intensified development of the Polish part of Uznam Island, there is an increase in the demand for drinking water in this area. This island ranks among areas with low water resources, which at the present time are allocated. In order to create the prospect of increased groundwater resources, a concept has been developed that allows for the recovery of part of the freshwater from drainage systems which discharge into the waters of Szczecin Lagoon or the River Świna. The present article discusses the secondary use of water from drainage systems for supply of the Wydrzany resource area. The notion of using water from the White Bridge pumping station was considered the most promising. The catchment area of the polder is 880 ha, 280 ha of which are located on Polish territory. The White Bridge pumping station transfers water from the polder, which it leads to the Peat Channel which, in turn, drains water gravitationally into Szczecin Lagoon. Here, results of simulations aimed at the use of drainage water to improve upon groundwater resources in the “Wydrzany” intake are discussed. On the basis of these simulations of artificial water supply to the intake, an increase of available resources by up to 50 per cent may be expected.
In-Situ and Laboratory Investigation on Leaching and Effects of Early Curing of Shotcrete
Authors: Sjölander Andreas , Ansell Anders
Published: January 2020

During the construction of a rock tunnel in Stockholm, several sections with leaching shotcrete (sprayed concrete) were found one year after the spraying was completed. An investigation was therefore conducted, and its results are presented in this paper. The amount of leaching after such a short time indicated that a one-sided water pressure existed in combination with a permeable shotcrete. The reason for the water pressure was likely a partly unsuccessful grouting that created sections with leaking water. The permeable shotcrete could be a combined result of insufficient curing and the use of accelerators, and the effect of in-situ curing was therefore investigated. A total of six slabs were sprayed and cured under different conditions in the tunnel. Test results according to standards indicated that curing has no significant effect on the development of mechanical strength or water penetration through the shotcrete. However, this is believed to be a result of the test method rather than the non-existing effect of curing. Lastly, some modifications to the test standard were proposed for future studies of in-situ curing.
Effect on Radon Exhalation Rate Due to Cracks in Concrete
Authors: Döse Magnus , Silfwerbrand Johan
Published: January 2020

The second largest cause of lung cancer in the World is related to radon (222Rn) and its progenies in our environment. Building materials, such as concrete, contribute to the production of radon gas through the natural decay of 238U from its constituents. The Swedish Cement and Concrete Research Institute (CBI), part of RISE (Research Institute of Sweden AB), has examined the effects of cracks in concrete on two different concrete recipes where an Ordinary Portland Cement, OPC-CEM-I concrete (REF) and an OPC concrete including a hydrophobic additive (ADD) were addressed. Two concrete prisms from each concrete recipe were examined. The radon exhalation rate was measured in the pristine state and after concrete cracks had been induced into the concrete prisms. Measurements were performed with an ATMOS 33 ionizing pulsation chamber. The results indicate a strong influence of cracks on the radon exhalation rate. An increase in radon exhalation rate was calculated for every test prism. The increase in radon exhalation rate varied between 80 and 260 %. The crack apertures may play a significant role on the exhalation rate. The concrete prisms with the largest apertures (ADD) also generated the highest radon exhalation rates. The results imply that there could be a substantial variation in the exhalation rate, due to numerous factors, but nonetheless, the results should, raise the awareness of the impact cracks in concrete structures, may have on the final exhalation rate of radon. The exhalation rate of the recipe with an additive (ADD) also showed a lower exhalation rate than for the reference recipe (REF), when compared in a pristine state. This was in part expected. However, the effect of induced cracks and its aperture, seemingly trumps the effect that an additive may play on the radon exhalation rate, when cracks are induced.

The hypothesis is in part verified in view of the results of the prism for the ordinary Portland recipe (REF-prisms), were an increase of approximately 100 % would be expected due to the total surface increase. The results also indicate this. The major increase in the radon exhalation rate of the ordinary Portland recipe including an additive, implies however other factors, such as minor internal cracks, that may substantially contribute to the final exhalation rate.
Emil Cioran – with Marin Sorescu

Published: January 2020

Marin Sorescu”s trips to Paris meant, each time, meeting Emil Cioran. The spiritual closeness between the two so different personalities develops over the years, as prooved by the numerous notes in the diaries of the Romanian poet. Despite the political restrictions of the regime, Marin Sorescu promotes Emil Cioran’s work in Romania, in the magazines of the time and in volumes. About his appreciation is written also in the correspondence between the two of them, we publish here some unique texts kept in the archive of Sorescu family.
Hermeneutical Perspectives In Matei Vişniec’s Poetical Discourse
Authors: Popa Savu
Published: January 2020

In Matei Vişniec’s literature, there is a gap between poetry and theater, which consists primarily on the ability of creating, in both species mentioned, areas or dramatic situations by using a parabolic or symbolic dimension of images. Matei Vişniec wrote poems that follow closely to the plays he wrote, which both his poems and plays including the same ingredients: the presence of characters, narrative situations, symbols, irony, and life seen as a complex spectacle. By using fantasy, the poet tends to transfer reality in a symbolic gap between the surface image and the depth image. Therefore, we will discuss two crucial aspects that involve the semnification of the theatrical dimension of look, by analysing a couple of important example of poems from his books and by consulting some critical point of views. In his poetry, we will find an interesting perspective of the so called the overturned look, which involves the relation of approaching and distancing between the surface image and the depth image. The first meaning of this dimension is to reveal a daily spectacle of life by presenting his apparently ordinary situations and people. In this case, the concept of mask will be discussed and its relation between essence and appearance. The second meaning involves the aspects that underline the loneliness and anxiety in the modern times.
From the prehistoric to the posthuman selfie
Authors: Stănese Radu
Published: January 2020

LeRoy McDermott’s hypothesis proposes a perceptual interpretation of the Venus statues from to the Upper Paleolithic period these being in fact the first examples of human self-representations. The arguments he brings are of an artistic nature par excellence and they refer to the visual distortions arising from the subject’s point of view. The fantasy of being admired by others through the means of the nude selfie has generated a whole trend in today’s pop culture and Kim Kardashian is a prime example in this sense. The “shareware body” has gone through an entire history of significance, from Albrecht Dürer’s mystical meaning of the body, to Érika Ordosgoitti’s activist take on the matter. The widespread presence of the nude selfie raises the issue of virtual identity “pornification” while Katherine N. Hayles’ hypothesis questions the future of a posthuman reality that has already been foreshadowed.

Published: January 2020

The objective of the study is the presentation of the chemical properties of forest chernozems and the features of forest habitats developed on chernozems in south-eastern Poland. The assessment of the trophic status of chernozems was presented based on the Trophic Soil Index (SIG). Moreover, the paper presents the diversity of forest vegetation on chernozems. The research covered 15 plots from the habitat inventory performed for the Mircze and Strzelce Forest Districts (SE Poland). Habitat conditions were characterised on the research plots, with particular consideration of the soil and vegetation. The analysed soils were featured by the presence of thick humus horizons and the occurrence of calcium carbonate. High SIG values confirm the eutrophic status of the analysed soils. In general, fresh and wet habitats of broadleaved forests (Lśw and Lw), as well as fresh habitats of broadleaved upland forest (Lwyżśw) develop on chernozems in Poland. They are associated with multi-species broadleaved tree stands. The conducted research indicates that, in current environmental conditions, the potential plant community is oak-hornbeam forest with predominance of oak, hornbeam, and abundant admixtures of other broadleaved species. High trophic status of the analysed chernozems is confirmed by high bonitation of tree stands and richness of forest floor vegetation.

Published: January 2020

The purpose of the paper was the description of classification of chernozems applied in agriculture, the agricultural suitability of these soils, as well as processes contributing to their degradation. The study showed that the principles of chernozems classification into subtypes and varieties have not changed significantly since the introduction of the bonitation classification and legend of the soil-agricultural map. Lower-order units in chernozems type include typical and degraded chernozems considering deluvial varieties for both units. Chernozems are one of the most fertile soils in Poland, mostly classified from I to III bonitation classes and 1, 2 and 8 of the soil suitability complex. They constitute only 0.8% of the total area of the country, and their largest areas are located in : Opolskie, Świętokrzyskie and Lubelskie Voivodeships. Intensive agricultural use causes that chernozems are subject to progressive degradation mainly due to plaugh and water erosion as well as acidification of the crop layer.
Visibilidad, corporalidad y publicidad en los discursos gorgianos
Authors: Álvarez Lucas Manuel
Published: January 2020

Nos proponemos en este trabajo resaltar un par de ejes significativos de la reflexión gorgiana soslayados por los intérpretes. Hablamos de los ejes de la visibilidad y de la corporalidad que, en el marco de un espacio público, parecen comportar para el sofista efectos quizás tan poderosos como los del lógos. Específicamente, indagaremos el rol que cumplen esas dimensiones en dos discursos gorgianos, Defensa de Palamedes y Encomio de Helena. En efecto, en sendas obras, la corporalidad y la visibilidad resultan, en mayor o menor medida, argumentos decisivos para demostrar la inocencia Palamades y exculpar a Helena respectivamente.
Perplejidades de la dignidad humana en el marco de los derechos humanos
Authors: Delgado Parra Concepción
Published: January 2020

Este ensayo postula que la noción de dignidad humana formulada filosófica y moralmente desde la civilización occidental moderna, demanda hoy una re-lectura de sentido, a la luz de las perplejidades que anidan en la disonancia entre los principios morales y el derecho legal justiciable de los Derechos Humanos en las democracias contemporáneas. Si bien, la noción de Derechos Humanos deriva de la pertenencia a la familia humana en la que se asienta idealmente la universalidad de sus titulares y por el principio de autonomía, el resultado de esta mixtura tiene su traducción en dos concepciones problemáticas: una abstracta del ser humano sobre la que se instrumenta una supuesta universalidad que derivó en otra individualista que convierte a los hombres en sujetos aislados y egoístas. Identificar el núcleo de esta perplejidad en Platón, Aristóteles y Benhabib, constituye el propósito de esta reflexión.

1. La experiencia de lo cotidiano [se] nos brinda siempre con anomalías, incongruencias, contradicciones. Y, cuando intentamos explicarlas, explicaciones a primera vista razonables acaban por revelarse insatisfactorias después de un examen más cuidadoso. La naturaleza de las cosas y de los acontecimientos no nos parece fácilmente inteligible. Las opiniones y los puntos de vista de los hombres son difícilmente conciliables o, incluso, unos con otros inconsistentes. Consensos quizá emergentes se muestran provisionales y precarios. Quien siente la necesidad de pensar con un espíritu más crítico e intenta comprender mejor, esa diversidad toda lo desconcierta.
Atributos divinos y el problema de la unicidad en Averroes
Authors: Delgado Gómez Joen Laureth , Castellanos Diego Giovanni
Published: January 2020

El artículo aborda la discusión acerca de la unicidad divina y la existencia de atributos, tanto en la filosofía como en la teología islámica medieval, haciendo énfasis en la obra de Averroes. Se analiza cómo en el pensamiento Islámico, al tiempo que se afirma el dogma de la unicidad divina se sostiene la existencia de atributos reales, apuntando directamente a conceptos dialecticos como unidad y multiplicidad, identidad y diferencia, o igualdad y alteridad. Así mismo, partiendo del análisis de su obra, se busca mostrar la manera en la que el pensador cordobés legitimó el uso de la razón filosófica como camino optimo y recomendado para el abordaje de las verdades religiosas. Se considera que Averroes avanzó en una doctrina teológico-filosófica particular diferente del asharismo que se estaba imponiendo en la época, resistiéndose a Al Ghazali, y reivindicando el valor la perspectiva peripatética para enriquecer el debate en el Islam.

Como alternativa al descenso en la rentabilidad del cultivo de café, principal fuente económica en el municipio de Inzá (Cauca, Colombia), se establecieron cultivos de pitaya amarilla sin conocer las limitantes fitosanitarias para este cultivo en esta zona. Este trabajo presenta la entomofauna asociada a cultivos de pitaya amarilla en tres predios productivos de Inzá, contrastantes por sus características agronómicas y de paisaje. Se realizó muestreo directo de insectos sobre cada estructura de la planta, muestreo con pases dobles de red entomológica a 50 cm de distancia de la planta y se consideraron factores abióticos e índices de diversidad ecológica. Con muestreo directo se reconocieron 58 familias, prevaleciendo Formicidae (n = 22), Coreidae (n = 11) y Lonchaeidae (n = 7). Con red entomológica se recolectaron cinco órdenes y 56 familias de insectos. Las plantas con mayor densidad de cladodios favorecieron a las familias Lonchaeidae (τ = 1,0; P = 0,00), Formicidae (τ = 1,00; P = 0,007) y Cicadellidae (τ = 1,00; P = 0,00). La precipitación (τ = 1,00; P = 0,00) y la temperatura (τ = 1,00; P = 0,00) se correlacionaron positivamente beneficiando a Lonchaeidae. No se encontraron daños asociados a Dasiops spp. (Diptera). No se confirmó la presencia de D. saltans porque todos los especímenes correspondieron a machos. Los índices de diversidad de Margalef (DMg) = 7,42; Shannon-Wiener (H’) = 3,217 (Alfa) y Whittaker (βw) = 1,0; y Routledge (βr) = 0,25 (Beta) representados principalmente por gran variedad de familias de insectos benéficos. Debe establecerse un sistema de vigilancia entomológica regular y acompañamiento técnico a los productores con miras al sostenimiento económico a largo plazo para este cultivo en el municipio.

Cubeba Officinalis is traditionally effective in the treatment of various kidney ailments, and the main adverse effect of tacrolimus is nephrotoxicity. There is no documented evidence about the ameliorative potential of Cubeba Officinalis in tacrolimus induced nephrotoxicity. The main endeavor of the study was to determine the nephroprotective activity of ethanolic extract of Cubeba Officinalis dried fruits against tacrolimus induced nephrotoxicity in Wistar albino rats. The Cubeba Officinalis dried fruits were collected from the local market, and Male albino rats weighing 200-250 g were used for the study. The dose of is lower 200mg/kg, higher dose 400 mg/kg of test drug (EECO) was used, and silymarin is used as the standard at the dose of 20 mg/kg. The animals were divided into five groups, six animals each, which is started prior to oral administration of tacrolimus and continued with the fourteen days tacrolimus treatment. After the whole period of study, the rats were sacrificed, and histopathological studies and biochemical estimations were carried out. The BUN values  were decreased from 33.60±3.84 in nephrotoxic rats to 28.27±2.48 (200mg/kg) and 20.70±0.81 (400mg/kg),creatinine levels from 1.645±0.21 to 0.926±0.19 (200mg/kg) and 0.638±0.07(400 mg/kg),uric acid levels from 1.822±0.249 to 1.092±0.306 (200 mg/kg) and 0.806±0.181 (400 mg/kg) sodium, potassium and chloride levels from 1.607± 0.091, 2.548± 0.293 and 259.8±6.42 to 1.302± 0.169 , 1.023±0.174 and 134.7±9.138 (200mg/kg of EECO) and 0.586±0.092 , 0.831±0.174 and 130.2±2.29 (400mg/kg of EECO).

Assessing public perceptions about road lighting in five neighborhoods of Tirana, Albania
Authors: Laze Kuenda
Published: January 2020

The light use was assessed in ten indoor and outdoor environments of Tirana, Albania, in November 2017. The five indoor environments presented one lecture hall, one library and three labs in a school environment. The five major streets of the capital city of Tirana presented outdoor environments. Questionnaires were respectively used to assess two criteria of “Vista” and “Visual comfort” of daylight in indoor environments and security, obstacle detection and visibility in outdoor environments. Lighting quality aspects of “Vista” were evaluated at a higher rank compared to “Visual comfort”. The approximately 87 and 60 percent of respondents respectively were not able to detect a pavement obstacle after the sunset (dark) or to distinguish a familiar face at a distance of 5 and 10 m in outdoor environments. Lighting was respectively inadequately comfort to 86 percent of users in five indoor environments. Road lighting after dark was not satisfactory to 60 percent of respondents in outdoor environments. These initial findings identify that lighting could generally be inadequate in indoor and outdoor environments in Tirana. Further research is required on the light use in built environments in Tirana, Albania.

This study was aimed to examine energy, density, proximate, dietary fiber and
macronutrients ratio on the glycemic index and glycemic load of 6 kinds Indonesian local
package menus made of red rice as a staple food and several other potentially antidiabetic
food ingredients. The design was a quasi-experimental with 20 participants each of which
were10 non-diabetic subjects (4 males and 6 females) aged between 20.3±1.0 years old
and 10 subjects with type 2 diabetes (5 males and 5 females) aged between 54.4±9.3 years
old. The results showed test package menu 1 (nasi liwet) has glycemic index and glycemic
load can be accepted as healthy menu package in both, non-diabetic subjects (glycemic
index = 23.8±9.2; glycemic load = 11.9±4.6) and diabetes subjects (glycemic index =
17.5±8.5; glycemic load = 8.7±3.3). There is a moderate to a strong negative correlation
between glycemic index and the incremental area under the curve with the content of
protein, fat, total dietary fiber, soluble dietary fiber, and moderate to strong positive
correlation with macronutrients ratio. In conclusion, prevention of increased postprandial
blood glucose in the management of type 2 diabetes mellitus diet can be done by
preparing a local Indonesian menu package based on red rice food ingredients by
considering the type of menu, protein, fat, total and soluble dietary fiber, and
macronutrient ratio.

(Labouring Under Strong Mental Derangement) the Wretched Woman
Authors: DeCoste Katherine
Published: January 2020

Single-sheet, cheap-to-print publications popularized in urban centres in the seventeenth and eighteenth centuries, broadsides were used to disseminate knowledge and entertainment among the common reading classes of England. Murder broadsides were a particularly common genre during the Victorian period in the mid-to-late-nineteenth century, and while the majority of these focused on the downfalls of male criminals, a significant number of publications concerning female murderers survives. Studying how broadsides were produced, read, and shared, especially in London, this paper examines the significance of their representations of female murderers. Ultimately, murder broadsides about women embodied the anxieties of the Victorian age. In the city, social boundaries were pushed, crossed, and blurred relentlessly; broadsides and their representations of women were active expressions of and responses to such anxieties. But while the tendency of broadsides was towards “moral conservativism” which sought to condemn violent crime, promote sexual purity, and sanctify chaste mothers and wives, broadsides also afforded the women they portrayed a certain notoriety and voice, complicating the common reading of the broadside as a prescriptive or even repressive document.
A Strange Half-World
Authors: Rudderham Hannah
Published: January 2020

The Second World War caused unprecedented population dislocation; 8 million people within the borders of Germany alone were categorized as displaced persons (DPs), civilians outside their national borders. While most were rapidly repatriated, nearly half a million Soviet DPs refused repatriation, and spent years of their lives in DP camps. This article seeks to better understand the experience of these DPs, for whom the camps were not merely a waystation, but a refuge. I examine three aspects of daily life in DP camps: coverage of basic needs, community building, and interaction with the world outside the camps, from the perspective of both DPs and camp personal to arrive at a more comprehensive understanding of the DP crisis. Doing so serves to humanize statistics, and offers insight into contemporary refugee crises.

This study aimed is to develop students’ soft skills through the implementation of the Culturally Responsive Transformative Teaching (CRTT) in chemistry learning. Indonesia's ethnic and cultural diversity is a challenge for teachers to design the chemistry lessons which is relevant with students’ characteristics. The research methodology applied is qualitative and applied on chemistry learning in the topics of acid and base, electrolyte and non electrolyte solution in five stages: self identification, cultural understanding, collaboration, critical reflections, and transformative construction. This research was conducted in two schools in DKI Jakarta and West Java in 2018. The data was collected by interview, reflective journal, and observations. The results showed that the chemistry learning through CRTT model can develop students' soft skills such as collaboration skills, critical thinking skills, nationality, social and cultural awareness, leadership, environmental caring, and curiosity. The teachers’ interview and reflections showed that the challenges in applying this approach were creativity in integrating cultural concepts in chemistry learning, students' understanding, time constraints, and the paradigm of students and teachers. Integration of ethnochemistry in CRTT can be developed in other chemical concepts with the principle of students’ character development

Forests have an important role in the life of living things. Nowadays forest fires (Karhutla) become a serious problem that can disrupt the symbiosis and life chain of living things. This problem has become a concern for the community, government and the world. Data obtained until August 2019 recorded 328,724 hectares and burned forest land. To overcome this problem, the government has made various efforts in the form of appeals or legal sanctions on actions that threaten forest sustainability whether carried out individually or in groups. Many cases of forest fires are known when a fire has occurred and little can be detected early. Information on the occurrence of many fires was obtained by residents around the location of the fire. To get the help of the fire department, community participation is needed, to contact the fire department so that they can anticipate the fire disaster early. The aim of this research is to develop a forest fire early warning system using the nodemcu module and the Telegram BOT with the Internet of Things (IOT) concept. Based on the test results of the Forest Fire early warning system using the Nodemcu module and the Telegram BOT with the concept of the Internet of Things (IOT) it is very helpful to provide quick information to find out fires that occur in the forest, by using the Internet of Things method, the officer will be able to know the conditions in real time, because this technology is capable of monitoring hardware using internet communication tools such as Telegram so that distance and location are not affected as long as the sensor used detects changes that occur.Keywords: Internet Of Things, Nodemcu, Telegram, Thingspeak, Forest fires

The journey to get to the Holy Land is somewhat complicated but along with the times, departing Umrah becomes easy because now many travel agents receive Umrah travel services. At present many agents accept Umrah travel services, but there are also some travel agents that are illegal and are not registered with the Ministry of Religion. Such travel agents harm Umrah pilgrims who want to practice their religion. With the price of cheap Umrah trips become an attraction for pilgrims and do not pay attention to the legality of the travel agent. And in the end pilgrims did not depart with various reasons to cover up the crime of the travel agent. For this reason, pilgrims need an application that can provide information searching for Umrah packages with consideration of the same facilities. And making this application can make it easier for prospective pilgrims to choose the same facilities with prices according to ability. Not only can know the price, prospective pilgrims can also see information on facilities and also the officiality (legality) of the travel agent. This research was conducted to make it easier for prospective pilgrims to choose facilities, prices and legality of the travel agent, and also apply the Rabin Karp algorithm and design a web-based Umrah package catalog application. Based on the results of the analysis, this system can help prospective Umrah pilgrims visitors with a success rate of 79.45% to determine the search results for prospective Umrah pilgrims.Keywords: umroh package catalog, rabin karp, string matching

Along with the development of technology at this time some programmers have found a solution to overcome the problem of storing important files that we worried about before the file security by making several applications that we often refer to as online file storage. Files saved to online file storage are usually document files and image files. However, the problem that arises is the image file has a large size and takes up large storage space and requires a long time in the process of exchanging data. To reduce the size of an image file compression techniques can be used. Compression is a way to compress data so that it only requires a smaller storage space so that it is efficient in storing or shortening time in exchanging information. Compression technique has several algorithms, in this study the authors used the Adaptive Arithmetic Coding algorithm. From the results of the study the authors managed to compress a color image file with jpg extension using the Adaptive Arithmetic Coding algorithm.

Security of data stored on computers is now an absolute requirement, because every data has a high enough value for the user, reader and owner of the data itself. To prevent misuse of the data by other parties, data security is needed. Data security is the protection of data in a system against unauthorized authorization, modification, or destruction. The science that explains the ways of securing data is known as cryptography, while the steps in cryptography are called critical algorithms. At this time, there are many cryptographic algorithms whose keys are weak especially the symmetric key algorithm because they only have one key, the key for encryption is the same as the decryption key so it needs to be modified so that the cryptanalysts are confused in accessing important data. The cryptographic method of Word Auto Key Encryption (WAKE) is one method that has been used to secure data where in this case the writer wants to maximize the encryption key and description of the WAKE algorithm that has been processed through key formation. One way is to apply the algebraic pascal triangle method to maximize the encryption key and description of the WAKE algorithm, utilizing the numbers contained in the columns and rows of the pascal triangle to make shifts on the encryption key and the description of the WAKE algorithm.Keywords: Cryptography, WAKE, pascal
