RHEOLOGY OF MORTAR WITH PORTLAND-LIMESTONE CEMENT CEM II/A,B-LL IN RELATION TO PROPERTIES OF CEMENT
Authors: GOŁASZEWSKA Małgorzata
Published: May 2019

The paper presents the results of rheological research, conducted to examine how the properties and composition of cement affects the yield stress and plastic viscosity of Portland limestone cements. Portland limestone cements used in the research were obtained by mixing four Portland cements of various chemical and phase compositions with two limestones of different origin, in an amount of 6, 10, 20 and 30% of cement mass. The yield stress and plastic viscosity were determined using the Viskomat NT rheometer, after 5 and 60 minutes from combining the constituents. Obtained results indicate a significant effect of the C3A content in cement on the rheological properties of mortars, mainly yield stress. The specific surface area of the tested cements has a lesser effect on the rheological properties of mortars with Portland limestone cements.
APPLICATION OF POTASSIUM FERRATE(VI) FOR OXIDATION OF SELECTED POLLUTANTS IN AQUATIC ENVIRONMENT – SHORT REVIEW
Authors: KLIŚ Simona , BARBUSIŃSKI Krzysztof , THOMAS Maciej , MOCHNACKA Anna
Published: May 2019

The paper provides comprehensive information on the recent progress of the use of potassium ferrate(VI) (K2FeO4) for the removal of selected pollutants from water and wastewater. K2FeO4 provides great potential for diverse environmental applications without harm to the natural environment. Therefore K2FeO4 was used in removal of cyanides from gold ore purification processes, degradation of dyes and organic compounds in wastewater and algae removal in the water treatment process. The quoted research results indicate that K2FeO4 due to its strong oxidizing and coagulating properties, could be an alternative to the use of Advanced Oxidation Processes (AOPs) or be an additional option to conventional methods of water and wastewater treatment. As a result of using K2FeO4, the emerge intermediates of the impurities decomposition are nontoxic or show less toxicity than the initial substrates. The use of K2FeO4 is also associated with certain limitations of technical and technological nature, which requires further research in order to use its high efficiency in the degradation of various types of contamination on a technical scale.

Published: May 2019

The present state of the environment in the rural area has been analyzed. The main factors which led to the existing situation have been revealed. The structure of Ukraine’s crops area and the amount of accumulated waste in Ukraine influencing the agricultural landscapes of rural areas have been analyzed. The dependence between the amount of accumulated waste and the incidence within the time interval was revealed. As a result of calculations, we have received the social losses due to an increase in the morbidity of the population living in the area of the impact of landfills, the coefficient of ecological stability of the studied territories was calculated and it was found that the presence of landfills reduces the coefficient of ecological stability. It has been revealed that with the help of satellite data monitoring of agricultural landscapes is possible, which can be used in calculating the price of land considering the quality factor of this land.
USE OF THE MACROMODEL DNS/SWAT TO CALCULATE THE NATURAL BACKGROUND OF TN AND TP IN SURFACE WATERS FOR THE RAC PARAMETER
Authors: WILK Paweł , ORLIŃSKA-WOŹNIAK Paulina
Published: May 2019

Total nitrogen (TN) and total phosphorus (TP) get into surface waters from both natural and anthropogenic sources. Anthropogenic sources have been relatively well recognised but the natural emmission of nutrients into the rivers, in the case of many catchments, remains a mystery. The paper describes the possibility of using a tool, the Macromodel DNS/SWAT (Discharge Nutrient Sea/Soil and Water Assessment Tool), to estimate the concentration and load of natural background (Natural Pollutant Concentration – NPC and Natural Pollution Load – NPL) for TN and TP and thus to specify the previously developed method of river absorption capacity – RAC. A variant scenario was developed allowing for a “virtual” change in the use of the area of an analysed catchment. This allowed the simulation of the amount of TN and TP in the waters of the main river, the Warta, in a situation where there was no anthropogenic phenomenon in the area. NPC and NPL results were obtained for six calculation profiles located on the central Warta main stream. On this basis, the total absorbency of the Total River Absorption Capacity – RACT River was calculated. The obtained results indicate an increasing pollution of the analyzed river on subsequent Surface Water Bodies (SWB). The values of RAC and RACt parameters for both TN and TP were reduced between the opening and closing profiles of the analyzed catchment by 2651 t/y (TN) and 86 t/y (TP), respectively.

Published: May 2019

A new species of the genus Geocenamus was isolated from soil and root samples from the rhizosphere of Casuarina equisetifolia (Casuarinaceae) in Quang Nam province, Vietnam. This species is characterized by a round-to-hexagonal labial disc, the presence of a labial region, which is continuous or slightly offset from the body with six sectors, lateral sectors of first labial annulus being smaller than the submedian sectors, the presence of six to seven labial annules; the absence of deirids; stylet length 24 to 28 μ m long, body length 776 to 979 μ m long; lateral field with six to eight lateral lines, without areolation at mid-body and with areolation in outer bands at the tail region and a pointed tail terminus. Geocenamus vietnamensis n. sp. most closely resembles G. boghiae in having a non-sclerotized head framework and lacking a bursa in the males. It can be clearly distinguished from all other species of the genus Geocenamus by these characteristics. The combination of morphology, morphometric features, and phylogenetic trees, based on D2–D3 of 28S and ITS rDNA sequences, showed that this new species can be clearly separated from all other sequenced species. This record is the first for Geocenamus in Vietnam.
Effect of the trap crop, Solanum sisymbriifolium, on Globodera pallida, Globodera tabacum, and Globodera ellingtonae
Authors: Dandurand L. M. , Zasada I. A. , LaMondia J. A.
Published: May 2019

The effect of the nematode trap crop Solanum sisymbriifolium was assessed against three Globodera spp., the potato cyst nematode Globodera pallida (in Idaho), the recently described Globodera ellingtonae (in Oregon), and the tobacco cyst nematode Globodera tabacum (in Connecticut) in field trials. At all locations the ability of S. sisymbriifolium to reduce Globodera encysted second-stage juveniles (J2) in egg densities compared to fallow was considered. For G. ellingtonae, the impact of planting and termination dates of S. sisymbriifolium on final egg densities was also evaluated; and for G. pallida, the ability of the nematode to reproduce on potato (Solanum tuberosum) after exposure to S. sisymbriifolium was determined. Encysted J2 in egg densities of all three Globodera spp. declined from 25 to 68% after trap cropping with S. sisymbriifolium. For G. pallida, S. sisymbriifolium reduced final encysted J2 in egg density by 23 to 50% compared to the fallow treatment, and significantly decreased G. pallida reproduction on potato after exposure to S. sisymbriifolium by 99 to 100% compared to the fallow treatment (P < 0.0001). For G. ellingtonae, the planting date of S. sisymbriifolium in May or June did not impact final egg densities (P = 0.32). Rather, percentage reduction in G. ellingtonae encysted J2 in egg density was most influenced by the length of time to which nematodes were exposed to S. sisymbriifolium, with 30 and 81% reduction after 6 vs 12 wk of exposure, respectively (P < 0.0001). Similar levels of nematode reduction after S. sisymbriifolium were observed for G. tabacum after 12 to 14 wk of exposure to the trap crop; G. tabacum density changes consisted of a 114% increase after susceptible tobacco, a 65% decrease after resistant tobacco, and an 88% decrease after S. sisymbriifolium compared to bare soil. In conclusion, this research demonstrates the widespread applicability of S. sisymbriifolium in reducing a diversity of Globodera spp. present in the USA.

Ligand Potency, Efficiency and Drug-likeness: A Story of Intuition, Misinterpretation and Serendipity
Authors: Polanski Jaroslaw , Pedrys Anna , Duszkiewicz Roksana , Kucia Urszula
Published: May 2019

The concept of ligand potency is briefly discussed here as well as why this is still a challenge for its complete comprehension. In this context, we explain also the meaning of ligand efficiency (LE), which has been greeted with both enthusiasm and criticism among the drug design audience. A full understanding of LE requires the complex interpretation of the potency concept presenting the uncertainty similar to this of the Zeno paradox. In reality, the efficiency of LE is caused by the high degree of preference for slim pharma drug candidates.
PPARγ: Potential Therapeutic Target for Ailments Beyond Diabetes and its Natural Agonism
Authors: Shafi Sana , Gupta Pawan , Khatik Gopal Lal , Gupta Jeena
Published: May 2019

Intense research interests have been observed in establishing PPAR gamma as a therapeutic
target for diabetes. However, PPARγ is also emerging as an important therapeutic target for varied
disease states other than type 2 diabetes like neurodegenerative disorders, cancer, spinal cord injury,
asthma, and cardiovascular problems. Furthermore, glitazones, the synthetic thiazolidinediones, also
known as insulin sensitizers, are the largely studied PPARγ agonists and the only ones approved for
the treatment of type 2 diabetes. However, they are loaded with side effects like fluid retention, obesity,
hepatic failure, bone fractures, and cardiac failure; which restrict their clinical application. Medicinal
plants used traditionally are the sources of bioactive compounds to be used for the development
of successful drugs and many structurally diverse natural molecules are already established as
PPARγ agonists. These natural partial agonists when compared to full agonist synthetic thiazolidinediones
led to weaker PPARγ activation with lesser side effects but are not thoroughly investigated.
Their thorough characterization and elucidation of mechanistic activity might prove beneficial for
counteracting diseases by modulating PPARγ activity through dietary changes. We aim to review the
therapeutic significance of PPARγ for ailments other than diabetes and highlight natural molecules
with potential PPARγ agonistic activity.
“Water” Use it - Wisely WSN-Irrigation System (WSN-IS) for Smart Home Garden
Authors: Durugkar Santosh R. , Poonia Ramesh C. , Naik Radhakrishna B.
Published: May 2019

Background:

India is the land of agriculture. Agriculture and gardening is not only done at a
huge level but also at small piece of land, it is a backbone of Indian economy. Small gardens are maintained
within the boundary of home. Water consumption in agriculture and gardening is at high level.
But due to irregular monsoon and decreased ground water level it is hard to irrigate the farm and gardens.
We have referred 03 patents which motivated us to revolutionize the agriculture sector.

Objectives:

Initial stages our scope is limited to home garden and we have proposed a GUI with which
end user can get many things such as pH of the soil, conductivity and TDS of the water, temperature
and humidity relationship, effect of temperature and humidity on the moisture, soil analysis, moisture
holding capacity of the soil etc. Irrigation plays important role in yielding of any plant. In this proposed
system, we have proposed a priority driven based irrigation model that supplies optimum and good
quality water to the crops with the help of Wireless Sensor Network.

Methods:

This proposed model is based on sensing the soil moisture, temperature, humidity and other
factor which affect the irrigation and supplies the water according to the priority of the requirement to
the plant. It is crop independent system, which can be implemented for basic crops, commercials crops,
garden and orchards, as basis for this proposed system is important to immediately irrigate the plant
wherever soil moisture level will be less. Smart irrigation is the new trend and we can say thirst now a
days and it is the major requirement due to many critical factors such as irregularity of monsoon, less
availability of water etc. Even though sufficient water is available still we have to make sure whether it
is good to use for better yielding of crops. At the same time temperature, humidity, air flow, soil moisture
will play important roles in better crop yielding. Wireless sensor network in which ‘n’ no. of issues
need to be discussed for the smooth execution of various tasks. Some challenges have been pointed out
through this work and important issues which must be considered.

Conclusion:

final testing shows how this approach is beneficial to the society. In agriculture and gardening
now onwards water consumption will be at low level. At the same time this proposed system
shows additional advantages to the end user i.e. quality of water utilization in terms of TDS, Conductivity
and pH of the water. Similarly, w.r.t. soil, if due to excess utilization of fertilizers and pesticides pH
is changing then also same thing will be noticed by avoiding future losses.
Anaerobic Glycolysis and Glycogenolysis do not Release Protons and do not Cause Acidosis
Authors: Pesi Rossana , Balestri Francesco , Ipata Piero L.
Published: May 2019

Background:

A metabolic pathway is composed of a series of enzymatic steps, where the product of each reaction becomes the substrate of the subsequent one. We can summarize the single reactions to obtain the overall equation of the metabolic pathway, suggesting its role in the metabolic network.

Objective:

In this short review, we aim at presenting our present knowledge on the biochemical features underlying the interrelation between acidosis occurring during anaerobic muscle contraction and the glycolytic and glycogenolytic pathways. We emphasize that both pathways per se are not acidifying processes.

Conclusions:

The review emphasizes the following points: i) The importance that single reactions, as well as the overall equation of a metabolic pathway, are balanced; ii) Unbalanced reactions lead to unbalanced overall equations, whose functions cannot be correctly understood; iii) Glycogen acts as the major fuel for muscle anaerobic contraction. Anaerobic glycogenolysis not only does not release protons, but it also consumes one proton; iv) When dealing with metabolic acidosis, it should be always recalled that protons are released by muscle ATPase activity, not by glycolysis or glycogenolysis.

Published: May 2019

BACKGROUND

Monitoring during pregnancy is vital to ensure the mother’s and infant’s health. Remote continuous monitoring provides health care professionals with significant opportunities to observe health-related parameters in their patients and to detect any pathological signs at an early stage of pregnancy, and may thus partially replace traditional appointments.

OBJECTIVE

This study aimed to evaluate the feasibility of continuously monitoring the health parameters (physical activity, sleep, and heart rate) of nulliparous women throughout pregnancy and until 1 month postpartum, with a smart wristband and an Internet of Things (IoT)–based monitoring system.

METHODS

This prospective observational feasibility study used a convenience sample of 20 nulliparous women from the Hospital District of Southwest Finland. Continuous monitoring of physical activity/step counts, sleep, and heart rate was performed with a smart wristband for 24 hours a day, 7 days a week over 7 months (6 months during pregnancy and 1 month postpartum). The smart wristband was connected to a cloud server. The total number of possible monitoring days during pregnancy weeks 13 to 42 was 203 days and 28 days in the postpartum period.

RESULTS

Valid physical activity data were available for a median of 144 (range 13-188) days (75% of possible monitoring days), and valid sleep data were available for a median of 137 (range 0-184) days (72% of possible monitoring days) per participant during pregnancy. During the postpartum period, a median of 15 (range 0-25) days (54% of possible monitoring days) of valid physical activity data and 16 (range 0-27) days (57% of possible monitoring days) of valid sleep data were available. Physical activity decreased from the second trimester to the third trimester by a mean of 1793 (95% CI 1039-2548) steps per day (P<.001). The decrease continued by a mean of 1339 (95% CI 474-2205) steps to the postpartum period (P=.004). Sleep during pregnancy also decreased from the second trimester to the third trimester by a mean of 20 minutes (95% CI –0.7 to 42 minutes; P=.06) and sleep time shortened an additional 1 hour (95% CI 39 minutes to 1.5 hours) after delivery (P<.001). The mean resting heart rate increased toward the third trimester and returned to the early pregnancy level during the postpartum period.

CONCLUSIONS

The smart wristband with IoT technology was a feasible system for collecting representative data on continuous variables of health parameters during pregnancy. Continuous monitoring provides real-time information between scheduled appointments and thus may help target and tailor pregnancy follow-up.
Exploring the Determinants of Mobile Health Adoption by Hospitals in China: Empirical Study (Preprint)
Authors: Ramdani Boumediene , Duan Binheng , Berrou Ilhem
Published: May 2019

BACKGROUND

Although mobile health (mHealth) has the potential to transform health care by delivering better outcomes at a much lower cost than traditional health care services, little is known about mHealth adoption by hospitals.

OBJECTIVE

This study aims to explore the determinants of mHealth adoption by hospitals using the technology-organization-environment (TOE) framework.

METHODS

We conducted an interviewer-administered survey with 87 managers in Chinese public hospitals and analyzed the data using logistic regression.

RESULTS

The results of our survey indicate that perceived ease of use (β=.692; P<.002), system security (β=.473; P<.05), top management support (β=1.466; P<.002), hospital size (β=1.069; P<.004), and external pressure (β=.703; P<.005) are significantly related to hospitals’ adoption of mHealth. However, information technology infrastructure (β=.574; P<.02), system reliability (β=−1.291; P<.01), and government policy (β=2.010; P<.04) are significant but negatively related to hospitals’ adoption of mHealth.

CONCLUSIONS

We found that TOE model works in the context of mHealth adoption by hospitals. In addition to technological predictors, organizational and environmental predictors are critical for explaining mHealth adoption by Chinese hospitals.
The Potential for mHealth Interventions to Support Women with Breast Cancer after Active Treatment
Authors: Singleton Anna , Raeside Rebecca , Partridge Stephanie R. , Sherman Kerry , Elder Elisabeth , Redfern Julie
Published: May 2019

Breast cancer is the most commonly diagnosed cancer among women worldwide. Chances of living one-year after diagnosis are high (~98%), and health self-management is essential to reduce risks of recurrence. Mobile health (mHealth) has emerged as a wide-reaching and cost-effective way of providing health information and support. Therefore, we conducted a narrative review of the currently available mHealth literature and synthesised the literature according to the impacts of mHealth interventions on patient outcomes, the potential mechanism for behaviour change and innovative approaches to developing future mHealth interventions. Results found a small amount of evidence for the value of mHealth interventions (text message programs, smartphone applications and activity trackers) for supporting women after breast cancer treatment. However, accessibility, cost and gender inequities may pose barriers to implementation. Developing consumer-led mHealth interventions based on lived-experiences will be essential to improving user outcomes. In conclusion, mHealth interventions are widely available and have the potential to support women after breast cancer treatment and further robust research will determine effectiveness in specific subgroups and populations.
Typographic Effect on Learning Management System Effectiveness
Authors: Morrison-Jones Natasha , North Teresa L.
Published: May 2019

Learning Management Systems (LMS) harness and share knowledge. The most extensive and well-populated knowledge networks are useless if they remain underutilized, with lower performing students 40% less likely to effectively use the LMS than higher performing peers. This study investigated the effect of four typographic elements—typeface, size, alignment, and emphasis—on perceived knowledge sharing effectiveness. With a sample size of 108 participants, typeface, size, alignment, and emphasis each had a significant (p < .05) effect on knowledge sharing effectiveness. Arial was the preferred typeface (p < .0001), 12-point the preferred font size (p = .0001), left or justified the preferred alignment (p < .0001), and sentence case the preferred emphasis (p < .0001). The ease and increased prevalence of adjusting these typographic elements thus leads to potential adverse effects on student use of LMS and their learning outcomes.

La integración de políticas ambientales y climáticas en México: el camino hacia una agenda de investigación para las ciencias político-administrativas
Authors: Solorio Israel , Miranda Carla
Published: May 2019

Desde hace un par de décadas la integración de políticas se ha vuelto parte central de las discusiones sobre política pública, emergiendo tanto como un concepto clave de la literatura académica como un objetivo de primer orden para políticos y tomadores de decisión. Gracias al impulso brindado por las negociaciones internacionales en materia, medio ambiente y cambio climático son dos agendas que han destacado como un laboratorio internacional para la integración de políticas. En 1987, la publicación del Informe Brundtland puso en el centro del debate la necesidad de transitar hacia un desarrollo sustentable que integrase las preocupaciones medioambientales a las decisiones económicas y sociales, llevando a políticos y académicos por igual a la necesidad de hablar sobre la Integración de Políticas Ambientales (IPA). En años más recientes, como resultado de la cambiante agenda medioambiental, el interés a nivel internacional por la IPA ha disminuido considerablemente para dar paso a la Integración de Políticas Climáticas (IPC). Para el caso de México, la aparición de la IPA como objetivo político coincide con la adopción del discurso sobre desarrollo sustentable. En similitud con la tendencia internacional, más recientemente el énfasis de la integración ha ido inclinándose hacia cambio climático, tal y como quedó demostrado con la adopción en 2012 la Ley General de Cambio Climático (LGCC) que incluye los principios de transversalidad e integralidad. Paradójicamente, pese a la creciente importancia de la IPA y la IPC como objetivos políticos a nivel nacional, hasta el momento es escasa la literatura académica que atienda casos empíricos sobre la materia en el contexto nacional. Con este telón de fondo, este artículo tiene el objetivo de sentar las bases para una agenda de investigación sobre la IPA y la IPC en México. Para ello, en las siguientes páginas se presentan los principales debates sobre la IPA y la IPC, vinculándolos con la realidad política y administrativa de México en aras de delinear futuras líneas de investigación sobre la política ambiental mexicana a partir del enfoque de integración de políticas.
Editorial. Del estrés oxidante, el deber del médico y otros temas
Authors: Fortoul van der Goes Teresa I.
Published: May 2019

La vida en nuestro planeta evolucionó de la simbiosis de una cianobacteria y un procarionte. La aparición de los cloroplastos y las mitocondrias permitió a los nuevos organismos generar una atmósfera oxidante, obtener energía e implementar mecanismos para contender con ese ambiente; así aparecieron los antioxidantes. Un desequilibrio entre los antioxidantes y los prooxidantes dará como resultado al estrés oxidante, que se asocia con varias patologías. El compromiso del médico para el cuidado de su paciente, este último más informado (que no bien informado), más exigente, pero menos comprometido con su participación en el proceso de curación. El ritual para la formación del kusiyai revela un proceso de iniciación y selección. Varios casos de interés se incluyen en este número, y finalizamos con las flores del Museo de Botánica de Harvard.

Water use spatio-temporal mapping linked to hydraulic fracturing across the Eagle Ford Play, Texas (USA)
Authors: Hernández-Espriú Antonio , Arciniega-Esparza Saúl , Macías-Medrano Sergio
Published: May 2019

Massive development of unconventional resources using hydraulic fracturing (HF) procedures, has been carried out since the last three decades, with focus on Texas, USA, including the Eagle Ford (EF) play. International concerns have been raised regarding water and environmental impacts closely related to shale production. The aim of this paper is to map spatio-temporal trends of HF development (water use and well density) examining the entire production period in the EF. We used FracFocus as the main source of HF information, from 2009 to 2017. Our database managed in Python, SAGA GIS and QGIS, comprised 15,013 oil and gas well records. Statistical results show that median HF water use has been progressively increasing over time, from ~18,000 m3/well (2010) to ~38,000 m3/well (2017). Mapping results illustrate that both well density and HF water use peaked in 2014, whereas the area required for HF encompassed ~16,800 km2 or ~70% of the play surface area. We summarize our results in a public domain interactive GIS-based digital map.

Se  consideraron variables personales (edad, sexo, capacitación en TIC, nivel educativo de formación inicial y conectividad) y su incidencia en los niveles de competencia digital autopercibido por 175 estudiantes pertenecientes a las carreras de Pedagogía de una universidad chilena de carácter público. Se empleó una escala diseñada ad hoc para el estudio, la que obtuvo muy buenas cualidades psicométricas en el proceso de validación. Los resultados arrojan que los futuros maestros sienten poseer ciertos conocimientos sobre el uso de TIC desde una perspectiva pedagógica, pero en el marco de un enfoque tradicional. Las variables personales que tienen incidencia en dicha valoración fueron la edad, el sexo, el nivel educativo de formación inicial docente.

Reseña del libro Invención, inmersión y alteración. Tres claves para pensar la didáctica en la clase universitaria
Authors: Della Giustina Sandra
Published: May 2019

En Reinventar la clase en la Universidad  Mariana Maggio, una de las referentes latinoamericanas en  educación y tecnologías de la información y la comunicación, propone pensar la noción de innovación en el nivel superior de la enseñanza, desde una  perspectiva didáctica. Se trata de una obra que pone en jaque a la clase universitaria tradicional anclada en la exposición, la verificación y la repetición. Como alternativa, Maggio invita a pensar las prácticas de enseñanza en el nivel superior a partir de tres nociones: invención, inmersión y alteración. Toma distancia de las didácticas tradicionales invitando a repensar la clase expositiva y la lógica lineal de los programas al tiempo que propone una nueva categoría teórica a la que denomina didáctica en vivo.
Plagiering i forskning. Videnskabsetiske og videnskabssociologiske aspekter
Authors: Andersen Heine
Published: May 2019

Plagiering betragtes normalt som en af dødssynderne i den akademiske verden,
en form for videnskabelig uredelighed. For forskere kan plagiering have
meget alvorlige karrieremæssige konsekvenser, fx tilbagekaldelse af akademiske
grader og disciplinære sanktioner. I Tyskland har to ministre indenfor
de senere år måttet træde tilbage efter at være blevet grebet i plagiering. Plagiering
ser ud til at være et voksende problem og kontrollen er skærpet. Mange
universiteter, forlag og tidskrifter har indført rutinemæssig plagiatkontrol.
Efter en gennemgang af selve begrebet betydning og formelle regler i videnskabsetiske
kodekser præsenteres og diskuteres forskellige etiske begrundelser
for forbud mod plagiering. Tre positioner diskuteres. En naturretlig: åndelig
ejendomsret, retten til viden, man selv har frembragt følger af retten til
”frugten af eget arbejde” (Locke), eller en ret, som er forudsætning for personens
dannelse (Hegel). Den har svag støtte. En utilitaristisk – funktionalistisk
begrundelse (Mill/ Merton): at plagiat undergraver videnskabernes anerkendelsesregime,
der skal belønne efter præstation til gavn for vidensvækst. Den
har stærkere støtte, om end funktionalitet kan være vanskelig at opnå og påvise
i praksis. Dysfunktionalitet og perverse effekter, fx på grund af for stærkt
publiceringspres, kan forekomme. Afslutningsvis inddrages Axel Honneths
anerkendelsesteori op som et supplement og korrektiv til utilitarismen.

ENGELSK ABSTRACT

Heine Andersen: PLAGIARISM IN RESEARCH. Research ethical and sociological aspects

Plagiarism is usually regarded as one of the deadly sins in science, a form of
scientific misconduct. Plagiarism can have serious consequences for researcher
careers, such as revocation of academic degrees and disciplinary sanctions.
In recent years, two ministers in Germany had to resign after being
caught in plagiarism. Plagiarism seems to be a growing problem, and many
universities, publishers and scientific journals have introduced routine control
for it.
After a review of meaning and formal rules of ethical codes, this article discusses
three ethical traditions, representing different reasons for prohibiting
plagiarism. The first is natural law: a right to spiritual property, to knowledge
that you yourself have generated. This is a right to “the fruit of one’s own labor”
(John Locke), or that which is essential for the person’s self-realization
(Hegel). There appears to be weak support for this position. The second is
a utilitarian-functionalist reason (Mill/ Merton): plagiarism undermines the
recognition regime in modern science, the principle of reward according to
contribution to the growth of knowledge. This position has greater support,
but it is often difficult to validate in practice. The strong pressure on researchers
to publish may create dysfunctional and perverse effects. Finally, Axel
Honneth’s theory of recognition theory is presented as a supplement and corrective
to utilitarianism.

Keywords: Plagiarism, scientific misconduct, research ethics.
Avaliação de escoamento pluvial em módulos de telhados verdes com diferentes substratos

Published: May 2019

A substituição de coberturas impermeáveis por coberturas verdes têm apresentado-se como uma alternativa ambientalmente adequada para a redução do escoamento superficial das águas da chuva. Nesse sentido, essa pesquisa avaliou a eficiência da composição do substrato de telhados verdes na redução do escoamento pluvial. Para tanto, foi realizado o monitoramento de eventos de chuva e vazão, considerando 40 sistemas experimentais (10 tratamentos, com 4 repetições em cada) de telhados verdes modulares, compostos por solo puro, substrato comercial puro e pela combinação de diferentes substratos: casca de arroz carbonizada, casca de arroz in natura e solo. Não houve diferença estatisticamente significativa na taxa de retenção média entre os tratamentos avaliados. Apesar disso, verificou-se que todos os tratamentos testados apresentaram taxa média de retenção do escoamento pluvial igual a 74%, o que demonstra o potencial de utilização de resíduos como a casca de arroz na composição de substratos para telhados verdes, visto seu custo ser mais baixo que o custo de substratos comerciais, devido às suas propriedades como leveza, porosidade e boa drenagem, além de constituir-se em uma alternativa ambientalmente adequada para a destinação desse passivo ambiental.
Characterization of the surface water of a municipal natural park by quality indexes

Conservation units are important for maintaining environmental resources. In this study, the water quality of the Lages Natural Park was evaluated by commonly used indexes: WQI, BMWP' and Shannon Diversity. Water and sediments were collected at seven points inside the CU and at one point outside it. For the evaluation of the WQI, nine parameters were measured: dissolved oxygen and temperature at the site, and the others at the laboratory. For the calculation of the BMWP' and Diversity indexes, the benthic macroinvertebrates in the sediment were identified. The BMWP' and Shannon indexes indicate a worse quality of the waters at the points 1, 2, 6, 7 and 8 (contaminated water and less diversity) than the WQI (quality ranging from good to optimal). The points 3, 4 and 5 had little polluted water according to BMWP' and optimal according to WQI. The results show the contamination of the water inside the park. There is a need for an investigation of its surroundings to determine the sources of contamination. It was also possible to prove the influence the riparian forest exerts in preserving the quality of the water. The difference in the sensitivity of the indexes proves the need to use biological analysis in water monitoring systems.

Published: May 2019

Mung bean (Vigna radiata (L.) Wilczek) is one of the plants that rich in antioxidant compound. Antioxidant is a compound that can inhibit the skin aging process because of photoaging. The aim of this study was to formulate peel-off gel mask containing mung bean (Vigna Radiata (L.) Wilczek) extract  using polyvinyl alcohol (PVA) as a base of mask and Hidroxy Prophyl Methyl Cellulose (HPMC) as a viscosity increasing agent and to determine the antioxidant activity of the peel-off gel mask. Antioxidant activity was tested using DPPH (1,1-diphenyl-2-pycrilhidrazil) assay. Mung bean was extracted by maceration method using ethanol 96%. The concentration of mung bean extract in the peel-off mask gel was 4% and various concentration of PVA were 5% (F1), 7.5% (F2), 10%(F3). The evaluations were organoleptic, pH, viscosity, drying and film forming, and gel spreadness. The study result showed that the organoleptic of the gel was brownish yellow with pH approximately 6, 196-513 cps in viscosity, 0.0646-0.0730 cm/g in gel spreadness and 27.6-54.5 second in drying and film forming. F3 containing mung bean extract 4%, PVA 10%, HPMC 2%, propylene glycol 15%, potassium sorbate 0,2%, olive oil 0,5%, alpha tocopherol 0,05 and aquadest ad 100% was the best formula with IC50 value was 85,2793 ppm and significantly different than F1 and F2 (p < 0.05).Keywords: peel-off gel mask, mung bean extract, Vigna radiata (L.)
