Authors: Apiñaniz Estibaliz , Salazar Agustín , Oleaga Alberto , Mendioroz Maria Aranzazu
Published: April 2020

Artikulu honetan, termografia infragorri aktiboaren bidez, pieza handietako pitzadura bertikalak karakterizatzeko metodo bat aurkeztuko dugu. Metodo honen bidez materialaren gainazala abiadura konstantez mugitzen den laser sorta batekin argiztatzen dugu, eta abiadura handiko kamera infragorri bat erabiliz gainazaleko tenperaturaren aldaketaren garapena neurtzen dugu. Gainazaleko pitzadura bertikalak uhin termikoentzat hesi termiko bat dira, eta, beraz, gainazaleko tenperaturaren profilean ez-jarraitasun bat sortzen dute. Matematikoki garatutako modelo teorikoa esperimentalki lortutako tenperatura profilarekin doituz, pitzaduraren ezaugarriak lor ditzakegu. Garatutako metodoa baliozkoa da laser sorta mugitu beharrean laserra geldi utzi eta lagina mugitzen dugunean; azken hori interesgarria da ekoizpen-kateetan pitzadurak in situ karakterizatu ahal izateko. Lan honetan, beraz, gure ikerketa taldeak pitzadura bertikalak karakterizatu ahal izateko jarraitutako ibilbidea azalduko dugu, eta lortutako metodoa balioztatzeko kalibratutako laginekin egindako neurketak aurkeztuko ditugu.

Published: April 2020

Azken hamarkada arte ez gara itsas ingurumenean mikroplastikoen (MPen) presentziaz kontziente izan. MPak itsaso eta kostaldeetan metatzen diren eta 5 mm baino tamaina txikiagoko plastiko-partikulak dira; zenbait produktu eta aplikaziotan erabilitako plastikozko material txikiak isurtzearen edo beste objektu handiago batzuen zatikapenaren ondorioz sortzen dira. Beraien arriskuaren benetako zenbaterainokoa ezezaguna da eta mundu osoan zehar jatorria, presentzia eta eraginak ikertzen ari dira. Lan honek MPei buruz munduan zehar egin diren hainbat ikerketa-lan bildu ditu, mundu-mailan itsas konpartimentu ezberdinetan MPei dagokienez aurkitu daitekeen egoera orokorra aurkezteko helburuarekin, mugak eta ezagutze-hutsuneak azpimarratuz. Itsaso-konpartimentu guztietan topatu dira MPak: ur-azalean, sedimentuetan (itsas hondoan, hondartzetan eta kostan, oro har) eta biotan; MP kopuruak nabarmenki aldatzen delarik behatutako konpartimentuaren, neurketa-teknikaren, eremu geografikoaren eta neurketa momentuaren arabera. Ikerketak alderatzeko zailtasunak nabarmentzen dira, erabilitako metodologia ezberdinak direla medio. Hori dela eta, prozedurak bateratzeko premiazko beharra dago. Mundu-mailan gehien ekoizten diren polimero motak izaki, polipropilenoa, polietilenoa eta poliestirenoa dira MPetan gehien azaltzen direnak. Ozeanoetako MPen banaketa eta eraginaren efektuei buruzko informazioa mugatua da oraindik. Horregatik guztiagatik, egindako lana sakondu beharra dago eskala ezberdinetan (lokalean, eskualdean eta mundu mailan): metodologiak adostu, monitorizazio-programak ezarri, iturriak hausnartu, MP sekundarioen degradazio-mekanismoetan sakondu, eta konpartimentuen arteko dinamikak eta ingurumenaren zein giza osasunaren gaineko eraginak aztertu.

Euskal kostaldean eta, nagusiki, estuarioetan, sedimentu ugari aurkitzen ditugu, egungo zein iraganeko giza jardueren eraginez substantzia toxiko ugari metatzen dituztenak. Horrek ingurumen-arazoak dakartza, eta sedimentu horiek modu egokian kudeatzera bultzatu behar gaitu. Horretarako, kutsatzaileok sedimentuetan duten portaera ulertu behar da, bai eta sedimentuen karakterizazio sakona egin ere. Gaur egunean indarrean dagoen legediak zenbait gidalerro eskaintzen dituen arren, hainbat lanek gidalerro horien mugak agerian utzi dituzte. Bereziki garrantzitsua da ohiko neurketa kimikoak sedimentuetan bizi diren organismoen ikerketekin uztartzea. Izan ere, haietan burutzen diren entseguek informazio oso baliagarria eskain dezakete sedimentuen toxikotasunaren eta, beraz, haien kudeaketa-beharraren inguruan. Entsegu horietarako erabiltzen diren bizidunek sedimentuan bizitzea eta han funtzio ekologiko garrantzitsua izatea komeni da. Horien artean Hediste diversicolor poliketoa dugu, sedimentuen kutsaduraren ebaluaziorako eta bioentsegu zehatz eta fidagarriak burutzeko organismo aproposa dena. Horiez gain, in vitro teknika egokiak eta sentikorrak garatu dira espezie honetan, eta horrela esperimentazioan erabiltzen diren bizidunen kopurua mugatu egiten da. Beraz, gure sedimentuetan metatutako kutsatzaileen maila altuek izan ditzaketen arriskuen ebaluazio fidagarria lor daiteke, baldin eta analisi kimikoak eta ekologikoki adierazgarriak diren espezieetan gertatutako efektuak (analisi ekotoxikologikoak) integratzen badira.

Ingurumen Hezkuntza iraunkortasunaren alde jardungo duten indibiduoak eratzeko ezinbestekoa da. Horretan, hezkuntza ez formaleko baliabide eta zentroetara ikasleek egindako irteerak garrantzi handia dute. Irteerak ordea, ez dira ondo pasatzeko egonaldi hutsak izan behar, hau da, buruturiko jarduerek ikasketa bat bultzatu behar dute. Lan honetan, bi tailer aztertu dira Kutxa Ekogunearen Bigarren Hezkuntzarako prestakuntza-programaren barruan. Programa hori EAEko beste zentro batzuetan aurki dezakegun eskaintza zabalaren adierazgarria izan daiteke. Diagnosia honetan identifikaturiko ahulguneak eta indarguneak kontuan izanik, hobekuntza proposamen bat egin da, alde metodologiko eta pedagogiko ezberdinetan oinarrituz.

Published: April 2020

Este trabalho integra e articula os principais resultados do projeto “Jogo patológico em 3D: Variáveis familiares, conjugais e individuais”, dispersos por cinco artigos científicos. Os resultados indicam que os jogadores patológicos constituem um grupo heterogéneo com diferentes severidades do problema jogo, revelando-se uma relação positiva entre o aumento da gravidade do jogo patológico e da quantidade e intensidade de dificuldadesindividuais, conjugais e familiares associadas. A ordem pela qual estas dificuldades se fazem notar parece colocar as dificuldades familiares e a diferenciação do self em último lugar e as dificuldades conjugais e individuais em primeiro. As áreas conjugal e familiar são pouco consensuais entre jogador(es) e cônjuge(s), sendo a perspetiva do(s) primeiro(s) menos marcada pelo défice ou mais otimista do que a do(s) segundo(s). A articulação destes dados conduziu a uma reflexão integradora sobre o tema, sistematizada através da reformulação do Modelo Sistémico Integrador do Jogo Patológico.
Intestinal cestodes of chicken are effectively killed by quinoline-rich extract of Spilanthes acmella
Authors: Lalthanpuii Pawi Bawitlung , Lalchhandama Kholhring
Published: April 2020

Background and Aim: Spilanthes acmella is used for the treatment of intestinal helminth infections in Mizo traditional medicine. In spite of a variety of drugs developed for helminthiases, an entirely safe and absolutely effective drug is still lacking, so much so that infections remain a major problem in human and animal welfare. In this study, we attempted to substantiate S. acmella as an anticestodal agent.

Materials and Methods: The aqueous extract of the aerial parts of S. acmella was prepared and from it a bioactive fraction was obtained using column chromatography. Chemical analyses were done using thin-layer chromatography (TLC) and gas chromatography–mass spectrometry (GC–MS). Helminth survival test was performed in vitro on an intestinal cestode, Raillietina tetragona. Structural effects on the cestode were examined under scanning electron microscopy.

Results: From the bioactive fraction of S. acmella extract, TLC indicated the presence of an aromatic quinone, which was identified using GC–MS as a quinoline derivative (2,2,4-trimethyl-1,2-dihydroquinoline having a retention time of 24.97 min and chemical formula of C12H15N). The quinoline-rich fraction showed concentration-dependent activity against R. tetragona as that of albendazole. Scanning electron microscopy of the treated cestode revealed classic anthelmintic effects such as tegumental shrinkage and damage of surface organs. The scolex was shrunk, suckers were degenerated with disintegrated spines, and rostellum was completely collapsed. There were severe damages on the tegument and formation of pit-like scars on the proglottids.

Conclusion: The efficacy of S. acmella extract and structural damages it caused on the cestode indicates that it is a potential source of anthelmintic agent and that 2,2,4-trimethyl-1,2-dihydroquinoline contributes to its antiparasitic activity.

Published: April 2020

A tanári pályán tapasztalható nehézségeket gyakran említik a kiégés-szindróma kialakulásával, és a pályaelhagyással kapcsolatban. Emiatt érdemes megvizsgálni, hogy melyek azok a nehézséget jelentő tényezők a pedagógusok számára, amelyek saját benyomásaik szerint akadályozzák őket a hatékony munkavégzésben. A kiégés-szindróma hátterében ugyanis sok tényező állhat, és ezek közül a személy számára leginkább erőteljesen észlelt faktorok fejtik ki legerősebben a hatásukat. Vizsgálatunkban két módszerrel alkottunk képet a pedagógusok észlelt nehézségeiről. Elsőként kvalitatív elemzéssel tártuk fel tanárok (N = 103) válaszaiból a munkájukat akadályozó okozó tényezőket. Ezt követően, a feltáró elemzés adatai alapján létrehozott kérdőívvel mértük fel a tényezők megítélést és összefüggéseit a kiégés tüneteivel pedagógusok között (N = 605). A feltáró eredmények szerint a legfontosabb nehézséget okozó tényező közé a munkához szükséges környezeti feltételek hiánya, a diákok magatartási nehézségei, a munka túl nagy mennyisége és az adminisztráció tartozik. A kérdőíves vizsgálat eredményei alapján a kiégés tüneteinek kialakulását a diákok viselkedése, a túlterheltség, a vezető negatív hozzáállása és a személyes kimerültség határozta meg legnagyobb mértékben. Az eredmények fontos információt tártak fel a hazai oktatásban jelenleg tapasztalható viszonyokról. Ez alapján számos olyan munkahelyi tényező azonosítható, amely jelentősen hozzájárul a tanárok kimerültségéhez és az őket érő stressz növekedéséhez. Az adatok fontos iránymutatást jelenthetnek intervenciós- és prevenciós módszerek kidolgozására, tekintve, hogy ezek a tényezők kapcsolatban állnak a burnout tüneteinek kialakulásával.

Authors: Nazneen Sahima , Rezapour Mashhadi Mahdi , Ksaibati Khaled
Published: April 2020

Indian Reservations have suffered from high crash rates that lead to fatal and incapacitating injuries for years. Among numerous issues, resource gap, rustic nature of the reservations, cross jurisdictional issues, and scarce crash data, act as obstacles in an effort to reduce the number of these fatal and serious crashes. Numerous organizations have recognized the importance of addressing issues on Indian reservations and improving roadway safety. Wyoming Technology Transfer Center / Local Technical Assistance Program (WYT2/LTAP) center developed a safety toolkit for tribal communities to ascertain high-risk crash locations and determine the low-cost safety improvement countermeasures. This safety toolkit acts as a guideline providing information, field examples, and resources in key topic areas to improve roadway safety through the use of the five-step methodology from Wyoming Rural Road Safety Program. These steps included compiling and crash data analysis, level I field evaluation, combined ranking, level II field evaluation, and benefit-cost analysis. In this study, the safety toolkit was implemented on the Fort Peck Indian Reservation (FPIR), Montana, to provide the tribes with a real-life example. This study reveals that low- cost safety countermeasures have significant impacts in reducing the number of fatal and serious injury crashes on the FPIR. This methodology with slight modification can be applied to other Indian reservations or similar entities to improve roadway safety.
Port deregulation and productivity in Nigeria: Some implications for economic regulators
Authors: Onwuegbuchunam Donatus Eberechukwu
Published: April 2020

Regulation in seaports broadly covers port safety, security, pollution and terminal operations which generally fall within the purview of national government’s administrative authority. Port deregulation policy in the era of global port reforms beginning in 1990’s, was introduced to limit government interference in commercial aspects of port operations, attract private sector funding and improve port productivity etc. However, in unregulated port market environment, the involvement of private sector in port terminal management can arguably generate risk of collusion especially among terminal operators offering the same or similar services. This paper examined port user welfare following private sector participation in a deregulated port environment. The Nigeria’s port terminal concession policy implementation was analysed as case study. From the findings, we demonstrated the essence for and role of economic regulator in ensuring that optimal port user welfare gains were achieved and maintained in post port reform regime.

Sensitivity analysis of performance of Nigerian ports using data envelopment analysis
Authors: Nze Obiageli N. , Ejem Ejem Agwu
Published: April 2020

With cognizance to some differences among the ports and complexities in productivity measurement, the research tries to identify and evaluate productive issues in terms of technical efficiencies (managerial efficiency) and scale efficiencies (managerial and allocative efficiency) experienced at individual Nigeria ports. It equally provided a technical benchmark for assessing the overall efficiencies of the respective ports in Nigeria during the pre-concessioned and post-concessioned era. The level of inputs required for each DMU to be efficient is given i.e. for DMU 2014 to be efficient input-wise, the number of berth may be reduced by two units as a result of idleness of this two (2) berths, the average turnaround time may be reduced by 3 hours and the berth occupancy may be reduced by 3%. Since a fixed asset such as berth cannot be reduced therefore technically and complimentarily the turnaround time and berth occupancy rate need to be decreased more than 5hours and 3% respectively by allocating the queue ship at the over-utilized berth to the idle berths which in turn will mitigate underutilization of this berths been required to be reduced or alternatively the port should embrace more cargo handling technology to enhance fast loading and discharging of cargoes thus attracting more vessels to the Port.

Authors: Branco José Eduardo Holler , Bartholomeu Daniela Bacchi , Vettorazzi Ana Carolina
Published: April 2020

Recentemente foi lançado pelo governo brasileiro o programa Renovabio, visando ampliar a participação do etanol na demanda por combustíveis para veículos leves e contribuir para o cumprimento das metas de redução de emissão de gases causadores do efeito estufa (GEE) firmadas no Acordo de Paris. O sucesso desse projeto pode ser favorecido por um sistema dutoviário que está sendo implantado e deve proporcionar uma alternativa logística de menor custo e com baixíssima emissão de GEE. Tendo em vista esse contexto, esse artigo propõe o desenvolvimento de um modelo de programação linear para otimizar os fluxos de transporte de etanol com o objetivo de mensurar as emissões de CO2 geradas pelas operações de transporte de etanol, assim como, para avaliar o impacto decorrente da implantação desse projeto dutoviário na mitigação das emissões de CO2 e na redução do custo de transporte. Os resultados indicam que a implantação plena dessa alternativa logística apresenta potencial para reduzir em 14% as emissões de CO2 e gerar uma economia de R$ 136 milhões por ano, no custo de transporte de etanol. O ferramental desenvolvido contribui para avaliar o impacto econômico e a mitigação de GEE causada por novas infraestruturas de transporte.

Published: April 2020

O Processamento Digital de Imagens (PDI) está estabelecido como ferramenta para a caracterização das propriedades de forma de agregados (forma, angularidade e textura superficial). Entre as principais técnicas de PDI, utilizadas na área de Infraestrutura de Transportes, está o uso do Aggregate Imaging Measurement System (AIMS). Este artigo tem como objetivo principal avaliar a qualidade das medidas das propriedades de forma de agregados, geradas com o uso de dois AIMS, através de análises estatísticas de repetibilidade e de reprodutibilidade. Para tanto, dois agregados de origem fonolítica, produzidos por diferentes processos de britagem, foram utilizados. Os resultados baseados em estatística descritiva e inferencial mostraram que houve repetibilidade e reprodutibilidade o que contribui na seleção de agregados, na fase de projeto, com propriedades de forma fornecidas a partir de curvas de distribuição e não por valores médios.

Published: April 2020

Em geral os defeitos em pavimento são identificados quando tornam-se visíveis a olho nu, sendo diagnosticados por meio de métodos destrutivos e de modo amostral. O ground penetrating radar (GPR) é um método de investigação não destrutiva (IND), utilizado no pavimento desde a década de 1970. Este trabalho tem como objetivo demonstrar a importância da modelagem numérica ao se trabalhar com GPR para a investigação de defeitos em pavimentos e suas gêneses utilizando o método das diferenças finitas no domínio do tempo no simulador numérico gprMax. Foram modelados levantamentos em três cenários: ausência de defeitos aparentes; afundamento por consolidação em trilha de roda e presença de tapa-buraco. As respostas obtidas por modelagem foram comparadas aos resultados dos levantamentos de campo. Como contribuição do artigo pode-se demonstrar a importância da modelagem como ferramenta na formação de profissionais; no planejamento dos serviços de campo, além de facilitar a interpretação dos dados.

Published: April 2020

Este estudo avalia o comportamento mecânico de três misturas asfálticas, uma de referência e duas com substituição dos agregados naturais por rejeitos finos de minério de ferro. Os rejeitos são provenientes de uma inovadora tecnologia de obtenção, a separação magnética a seco. A metodologia consistiu de um programa experimental dividido em quatro etapas: (i) determinação das características físicas, mineralógicas e ambientais dos agregados; (ii) obtenção as propriedades reológicas e empíricas do cimento asfáltico de petróleo; (iii) dosagem dos materiais de revestimento asfáltico pela metodologia Superpave; (iv) realização de ensaios de dano por umidade induzida, resistência à tração por compressão diametral, fadiga à tensão controlada, módulo de resiliência e uniaxial de cargas repetidas nas misturas asfálticas. Os concretos asfálticos que continham agregados alternativos apresentaram propriedades de rigidez e fadiga similares à mistura de referência. Entretanto, com a utilização de rejeitos de minério de ferro houve maior susceptibilidade ao acúmulo de deformações permanentes.
Avaliação da percepção de segurança em relação à presença de três tipos de infraestrutura cicloviária em cruzamentos não semaforizados
Authors: Diniz Claudinei Moreira , Ferreira Marcos Antônio Garcia
Published: April 2020

Nos cruzamentos, a concentração de pontos de conflito e a necessidade de circulação em meio ao fluxo de veículos motorizados causa nos ciclistas uma maior sensação de insegurança. Desse modo, o presente estudo analisa a percepção de segurança viária em cruzamentos urbanos não semaforizados em relação a presença de infraestrutura cicloviária dedicada aos ciclistas. A metodologia foi baseada na coleta de dados por questionário on-line que buscou identificar a percepção de segurança de usuários de bicicleta para uma série de cenários, com e sem a presença de infraestrutura cicloviária. Os dados foram analisados por meio de métodos de estatística descritiva e inferencial, nos quais foram comparadas as respostas por tipo de infraestrutura e por tipo conflito. Os resultados encontrados mostram que cenários com a presença de ciclovia no canteiro central tendem a ser percebidos como os mais seguros, enquanto que cenários com vias compartilhadas são percebidos como os mais inseguros.

Published: April 2020

The purpose of law is to implement the ideals of order and justice into the interpersonal space of life that is society. Therefore, every legal regulation must abide and be based on norms that exist in society which envisages the modern ordered and just society. The law should be prospective, understandable, clear, fixed and certain. In Indonesia, Pancasila is a set of five principles by which the whole systems of government, law, and social life should be adopted by the nation. However, the current political climate has changed the political reception towards reinforcing Pancasila as the basic philosophy of regulation-making. This conceptual article discussed about how the process of regulation-making should be based on Pancasila as grundnorm, or basic norms of the nation’s life. This article concluded that the elaboration of the grundnorm in the formation of laws and regulations by taking into account the principles of the formation of laws and regulations as well as the principles of material content along with the guidelines and techniques for their formation, so that the formation of laws and regulations fulfills the rules in substance (materially) and formally.
THE IMPORTANCE OF LAND REGISTRATION TO SUPPORT SUCCESSFUL ENVIRONMENTAL MANAGEMENT
Authors: Ardani Mira Novana
Published: April 2020

Land registration provides legal certainty and protection to holders of land rights. In its implementation it does not always go well, so that what is the goal can not be achieved. A person or legal entity cannot prove that he is the legal owner of a parcel of land. This can lead to land conflicts. Land conflicts can cause overlapping land tenure and overlapping land permits which often results in environmental damage. This research uses a normative juridical approach. Normative juridical research is research focused on examining the application of rules or norms in positive law. The research objective is to find out what ways can be done so that through land registration activities can support the success of environmental management. The results of the study explained that land registration activities through systematic land registration acceleration resulted in land certification for plots of land that had met the requirements, and could strengthen the one map policy database, so that administrative order could be achieved. It also makes land use plans to support the achievement of national development goals and the greatest prosperity of the people,  so as to realize environmental sustainability.

Authors: Rayhan Glenn Mochamad , Fachrina Salsabila , Amalia Rizka
Published: April 2020

Paper production has been identified with industries that destroy forests (deforestation). Utilizing alternative wood substitute raw materials, such as pineapple leaves can be one solution to the problem. Pineapple plants can produce more than 70 leaves with cellulose content in the leaves which reaches 69.5-71.5%, so it has the potential to be used as raw material for paper. The organosolv process was chosen as a pulp manufacturing process because it produces high purity in the byproducts (lignin and hemicellulose), high pulp yield, easy recovery of black liquor and no sulfur element, making it safer for the environment. This study aims to determine the most influential factors in the organosolv pulping process with a factorial experimental design method 23. Variables used include solvent types (ethanol and acetic acid), pulp cooking time (60 minutes and 110 minutes) and types of leaf dryness (wet leaves) and dried leaves). From the results of the analysis, the most influential factor in the organosolv pulping process is the type of solvent (ethanol). Optimal operating conditions were obtained for solvent ethanol, cooking time of 60 minutes with wet leaves, where cellulose content was 96.31% and lignin content decreased by 17.80% in dry pulp.

Therefore it must be maintained so that it is always in good condition with regular maintenance. Prior to maintenance, PMT is terminated from the bus bar, which is called the rack out process. After maintenance, the PMT is reconnected with the bus bar, which is called the rack in process. Usually, 20 KV PMT rack in and rack out process in maintenance or disturbance is still using the manual method. The 20 KV PMT can only be racked in and racked out in one way, by turning the lever. The lever will rotate the bolt as a PMT rail. In the manual method, there is no system for monitoring the condition of the bus bar whether it is has electric-voltage or not. There is also no remote control that can rack in and rack out. So officers must ensure the conditions of PMT and bus bars are safe manually, before maintenance is carried out. This is quite troublesome and dangerous for officers. From these problems, in this research  designed a system that could ensure the condition of the PMT and the bus bar was safe before the rack in and rack out process was carried out and could monitor and control the system remotely using SCADA. Rack-in and rack-out automation system using VT SCADA, using Ethernet Shield that has been connected with Arduino Mega. Ethernet is connected to a mini PC. The microcontroller pins will be connected to the relays that will turn or stop the motor. The rack in and rack out commands from VT SCADA will determine the rotation of the motor so that the PMT moves. The current sensor reads the current flow and detects interference. Interference detection will automatically make PMT Rack out. System testing shows that the process of racking out in a state of maintenance or disturbance can be carried out automatically controlled by VT SCADA. Current sensor works to detect the current flowing, so that it can detect PMT interference and perform automatic rack out. The rack-in process is also capable of being remotely controlled with VT SCADA. This makes it easier for officers to also become additional reliability of PMT in the 20 KV cubicle.

Smart agriculture has an emerged concept by using IoT sensors capable of providing various information about their field condition and conducting environmental monitoring to improve the yield of efficient crops. This research aims to develop a microclimate monitoring system in a closed house. The microclimate being monitored is the effective temperature, which is the temperature felt by broilers at that time in a fast area. In this research, IoT has been implemented using WeMos D1 R32 by sending sensor data to observe the effective temperature parameters as actual temperature, humidity, and wind speed into an MQTT cloud server. Microclimate control in the cage is based on effective temperature. The data can be displayed on a 16x4 LCD screen and accessed via an Android smartphone from anywhere and at any time.

Published: April 2020

The paper presents the impact of the initial processing, cultivar, and storage time on the physico-chemical quality of freeze-dried crisps. Sweet pepper after initial washing and crushing was subjected to further four combinations of the initial processing. The first combination included freezing, the second one blanching in 98°C and 2-minutes time, the third one -dehydration in 2% solution of ascorbic acid and the fourth one -dehydration in 2% solution of sodium chloride. Both types of dehydration were carried out in 70°C for 20 minutes with a 1:4 participation of raw material to osmotic solution. Blanched and dehydrated raw materials were subjected to freezing in -18°C for 24 hours. After the completed process of freezing, the samples were moved to a freezer-drier and were dried by sublimation in -18°C and the reduced pressure of 63 Pa. Based on the research analyses a significant variability of physico-chemical properties of the obtained freeze-dried sweet pepper with regard to a cultivar, processing type and storage time were reported. Freeze-dried yellow sweet pepper was the most similar to the fresh raw material. It was dehydrated in the ascorbic acid solution. The storage time considerably influenced the reduction of the quality properties of sweet pepper crisps.

The paper presents the impact of the initial processing, cultivar, and storage time on the physical and chemical quality of freeze-dried sweet pepper crisps. Sweet pepper after initial washing and crushing was subjected to further four combinations of the initial processing. The first combination included freezing, the second one blanching in 98°C and 2-minutes time, the third one -dehydration in 2% solution of ascorbic acid and the fourth one - dehydration in the 2% solution of sodium chlo-ride. Both types of dehydration were carried out in 70°C for 20 minutes with a 1:4 participation of raw material to osmotic solution. Blanched and dehydrated raw materials were subjected to freezing in -18°C for 24 hours. After the completed process of freezing, the samples were moved to a freezer-drier and were dried by sublimation in -18°C and the reduced pressure of 63 Pa. The research that was carried out proved that the microbiological quality of the obtained sweet pepper lyophilizes was significantly affected by the cultivar, treatment type and storage time. These factors significantly diversified the number of micro-organisms in sweet pepper crisps. No initial processing before sublimation drying caused a considerably average increase of the number of psychrophile and mesophilic bacteria in crisps from both sweet pepper cultivars. A considerable reduction of their total number took place during blanching and dehydration in the ascorbic acid solution and sodium chloride solution. Additionally, along with the storage time, reduction of the total number of psychrophilic, mesophilic bacteria, fungi and yeasts was reported.
If I knew they were the expression of creativity in people with blindness, I would rate them higher - Bias in Evaluating the Work of People with Blindness

Objective: In our pilot study, we tested to what extent subjective understanding and aesthetic appreciation of em-bossed drawings were dependent on the information that their creators were people with disability. Method: Our research was carried out in a gallery of contemporary art with 30 adults who were non-experts in the field of visual arts. Subjects were asked to view the current exhibition and then evaluate their subjective understanding and aesthetic appreciation (liking and interest) of 12 embossed drawings on seven-point scales. Results: Participants who were aware that persons with blindness had created the drawings (the informed group) in contrast to those who remained unaware (the uninformed group) declared – both – greater subjective understanding and higher appreciation of the exhibited works. In the informed group (N = 15), in comparison to the uninformed group (N = 15), the correlation between appreciation and subjective understanding of artwork was stronger. Conclusions: We discuss our pattern of results considering the attributional approach to creativity (Kasof, 1995) and the model of a cognitive mastering process of aesthetic experiences (Leder, Belke, Oeberst, & Augustin, 2004). Our results can be used, among others, by educators working in art galleries and museums.
Students and Teachers Implicit and Explicit Theories of Creativity

Published: April 2020

The current research aims to analyse ways of conceptualising the termcreativitywith the help of drawings, as a form of cognitive rendering by primary school students, pedagogy students and primary school teachers. The research seeks to find answers to three questions: What common notions of creativity are held by both primary school pupils and teachers and pedagogy students? Are there any differences in the understanding of this term among these groups of people? How far is the implicit, personal understanding ofcreativityin line with the scientific notion of this term? The visual ethnography method was applied in the study. Qualitative visual data (177 drawings of pupils, students and teachers) were used as the main source of data for analysis in addition to verbal data (written descriptions by the participants). Empirical data were analysed from the perspective of both an elitist and egalitarian approach to creativity, and using various ways to define creativity, as well as selected understandings of the term. Analysis of the qualitative data, demonstrated that pupils, students and teachers are able to treat creativity holistically and systematically, although they tend to associate creativity with the person who is the creator or with a broadly understood product, rather than the process or external circumstances that support creative activity. The research suggests that pupils’ definitions of creativity focus around four aspects of meaning: 1) creativity as self-expression; 2) creating new things; 3) ability to utilise the internal resources of imagination and creative thinkingoutside the system; 4) participation in solving everyday problems. Furthermore, it is possible to say that the knowledge of teachers in this matter is more consistent (cultural knowledge) and that of students is more personal (atypical, original, referring to a larger number of different problems and themes).

Published: April 2020

The research is intended to determine the absorption behavior of a newly fabricated, sansevieria cylindrica–reinforced vinyl ester composite (SCVEC) under a different immersion medium. For this purpose, seawater, distilled water, and groundwater was taken. The samples of untreated and sodium hydroxide (NaOH)-treated SCVEC with varying fiber content and fiber length was subjected to water absorption studies. The diffusion coefficient, permeability coefficient, and sorption coefficient were determined to study the kinetics of water molecules penetrating the SCVEC. The results show that SCVEC can resist seawater effectively compared to other medium. This is because of the salt molecule, which disables the secure transport of water molecules into the composite. NaOH-treated composites showed better results compared to the untreated composites irrespective of immersion medium. Scanning electron microscopic studies reveal the water absorption mechanism of SCVEC materials.

Natural genetic variants of Neuregulin1 (NRG1) and its cognate receptor ErbB4 are associated with a risk for schizophrenia. Whereas most studies on NRG1-ErbB4 signaling have focused on GABAergic interneurons, ErbB4 is also expressed by midbrain dopaminergic neurons where it modulates extracellular dopamine (DA) levels. Here, we report that extracellular steady-state levels of DA are reduced in the medial prefrontal cortex (mPFC; −65%), hippocampus (−53%) and nucleus accumbens (NAc; −35%), but are elevated in the dorsal striatum (+25%) of ErbB4 knock-out mice (ErbB4 KOs) relative to wild-type controls. This pattern of DA imbalance recapitulates the reported prefrontal cortical reduction and striatal increase of DA levels in schizophrenia patients. Next, we report on a battery of behavioral tasks used to evaluate locomotor, cognitive and motivational behaviors in ErbB4 KOs relative to controls. We found that ErbB4 KOs are hyperactive in a novel open field but not in their familiar home cage, are more sensitive to amphetamine, perform poorly in the T-maze and novel object recognition (NOR) tasks, exhibit reduced spatial learning and memory on the Barnes maze, and perform markedly worse in conditioned place preference (CPP) tasks when associating cued-reward palatable food with location. However, we found that the poor performance of ErbB4 KOs in CPP are likely due to deficits in spatial memory, instead of reward seeking, as ErbB4 KOs are more motivated to work for palatable food rewards. Our findings indicate that ErbB4 signaling affects tonic DA levels and modulates a wide array of behavioral deficits relevant to psychiatric disorders, including schizophrenia.
