Authors: Sebe Emese , Nagy Gábor , Kállay András Arnold
Published: November 2019

A pirolízis ígéretes eljárás hulladékokból történő szintézisgáz előállításra. Azonban a technológia melléktermékeként visszamaradó szilárd anyag még jelentős mennyiségben tartalmazhat karbont, ezáltal akár további szintézisgáz előállítására is felhasználható. Kísérleteink során egy Zalaegerszegen működő félüzemi méretű kísérleti pirolizáló berendezésből származó RDF pirolízise során visszamaradó koksz vízgőzzel történő elgázosítását vizsgáltuk 900 °C-on, egy fix-ágyas laboratóriumi elgázosító rendszerben. Továbbá végeztünk kísérleteket felsőnyárádi barnaszénnel is. Jelen munka célja, hogy megvizsgáljuk hatékonyan alkalmazható-e a pirolízis koksz szintézisgáz előállítására, valamint, hogy feltárjuk és bemutassuk a vizsgált alapanyagok termokémiai lebontása során felfedezhető hasonlóságokat és különbségeket.

A Miskolci Egyetem Műszaki Földtudományi Karán működő Fenntartható Természeti Erőforrás Gazdálkodás Kiválósági Központban elvégzett kutatások eredményei azt mutatják, hogy a megfelelő előkészítést alkalmazva és a körülményeket optimálva a hulladék alapanyagok eljárástechnikai jellemzőinek (szemcseméret eloszlás, fajlagos felület) megváltoztatásával az építőanyag termékek fizikai és mechanikai tulajdonságai (szilárdság, tömörség) javíthatók. Kutatásaink ugyanis kimutatták, hogy a kémiai aktiválás mellett a mechanikai aktiválás is egy igen hatékony eszköz a tulajdonságok szabályozására. Ez azonban  megváltoztatja nemcsak a termék fizikai, mechanikai, hanem a szerkezeti, ásványtani jellemzőit is, ezért ezen jellemzők meghatározása is kiemelten fontos.
Az Ipar 4.0 keretrendszere, valamint a kapcsolódó technológiák
Authors: Oláh Judit
Published: November 2019

Az erősödő verseny és a globalizáció következtében megváltozott a vállalatok mikro- és makrokörnyezete. Az Ipar 4.0 a negyedik ipari forradalmat jelenti, amely során szorosabban fonódik össze az információs technológia és az automatizálás, ezáltal alapvetően megváltoznak a gyártási módszerek. Nem csupán a technológia térhódításáról van szó, hanem az üzleti folyamatok paradigmaváltásáról is. Az Ipar 4.0 a hazai vállalatok számára is egyre inkább napi valósággá válik, egy új szintre fogja emelni a gyártásban felhasznált erőforrások és szereplők közötti interakciókat. Véleményem szerint az Ipari 4.0 át fogja alakítani a termelés szerkezetét – és meg fogja változtatni a globális versenyképességet – új lehetőségeket ad a vállalatoknak az értékteremtéshez. Kutatásomban bemutattam az Ipar 4.0 fogalmát, az újszerű technológiáit, keretrendszerét és a kapcsolódó technológiákat, feltártam az intelligens logisztikai megoldásokat és az Ipar 4.0 legfontosabb előnyeit. A fenti eszközök használatakor lényegében nem csak az ipar robbanásszerű fejlődéséről van szó, hanem a teljes gazdaság digitalizációjáról, mely az egész társadalmat érinti. Fontos, hogy a kis- és középvállalkozások is reagáljanak az új technológiai lehetőségekre, egyébként jelentős mértékben lemaradnak.
Nanoanyagok alkalmazásának munkabiztonsági vonatkozásai
Authors: Zákányiné Mészáros Renáta , Járdán Eszter , Zákányi Balázs Zsolt
Published: November 2019

Napjainkban, köszönhetően speciális tulajdonságaiknak a nanoanyagok egyre jelentősebb érdeklődést keltenek, ipari alkalmazásuk egyre inkább terjed. Különleges tulajdonságaikat főként annak köszönhetik, hogy a nanoanyagok főbb jellemzői nem minden esetben ugyanolyanok, mint ugyanannak az anyagnak a normál mérettartományú változata, sőt adott esetben akár jelentősen eltérhetnek, mindez főként a megnövekedett felületnek, illetve a kis méretű anyagok speciális fizikai-kémiai tulajdonságainak köszönhető. Miközben ezen anyagok az iparban jelentős új funkciót töltenek be, a környezettel és a biológiai szervezetekkel kialakuló kölcsönhatásaik egyre kiszámíthatatlanabbak, így alkalmazásuk kapcsán például humánbiztonsági szempontból a bizonytalanság egyre nagyobb. A rendkívül gyors technológiai fejlődés következtében ezen anyagok jóval hamarabb alkalmazásra kerültek, mint ahogyan az alkalmazásukhoz kapcsolódó jogi szabályozás kialakulhatott volna, így jelenleg a nanoanyagok alkalmazására vonatkozó kötelező érvényű rendelet jelenleg nem érhető el. Jelen pillanatban a nanoanyagot gyártó maga felel a termékek biztonságáért. Természetesen, mindemellett a kémiai biztonsághoz kapcsolódó jogi szabályozás és szabványok kezelésükhöz kiváló alapot jelentenek, azonban az anyagok specifikus tulajdonságai, újszerűsége és a hatásmechanizmusra vonatkozó hiányos ismeretek következtében egy kockázatértékelés elkészítése mégis kihívást jelenthet a szakember számára.
Optimizing the combustion processes of a small scale solid fuel-fired boiler
Authors: Mentes Dóra , Sajti Zoltán , Koós Tamás László , Póliska Csaba
Published: November 2019

Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.
Internet Searches for Medical Symptoms Before Seeking Information on 12-Step Addiction Treatment Programs: A Web-Search Log Analysis
Authors: Nitzburg George , Weber Ingmar , Yom-Tov Elad
Published: November 2019

Background

Brief intervention is a critical method for identifying patients with problematic substance use in primary care settings and for motivating them to consider treatment options. However, despite considerable evidence of delay discounting in patients with substance use disorders, most brief advice by physicians focuses on the long-term negative medical consequences, which may not be the best way to motivate patients to seek treatment information.

Objective

Identification of the specific symptoms that most motivate individuals to seek treatment information may offer insights for further improving brief interventions. To this end, we used anonymized internet search engine data to investigate which medical conditions and symptoms preceded searches for 12-step meeting locators and general 12-step information.

Methods

We extracted all queries made by people in the United States on the Bing search engine from November 2016 to July 2017. These queries were filtered for those who mentioned seeking Alcoholics Anonymous (AA) or Narcotics Anonymous (NA); in addition, queries that contained a medical symptom or condition or a synonym thereof were analyzed. We identified medical symptoms and conditions that predicted searches for seeking treatment at different time lags. Specifically, symptom queries were first determined to be significantly predictive of subsequent 12-step queries if the probability of querying a medical symptom by those who later sought information about the 12-step program exceeded the probability of that same query being made by a comparison group of all other Bing users in the United States. Second, we examined symptom queries preceding queries on the 12-step program at time lags of 0-7 days, 7-14 days, and 14-30 days, where the probability of asking about a medical symptom was greater in the 30-day time window preceding 12-step program information-seeking as compared to all previous times that the symptom was queried.

Results

In our sample of 11,784 persons, we found 10 medical symptoms that predicted AA information seeking and 9 symptoms that predicted NA information seeking. Of these symptoms, a substantial number could be categorized as nonsevere in nature. Moreover, when medical symptom persistence was examined across a 1-month time period, a substantial number of nonsevere, yet persistent, symptoms were identified.

Conclusions

Our results suggest that many common or nonsevere medical symptoms and conditions motivate subsequent interest in AA and NA programs. In addition to highlighting severe long-term consequences, brief interventions could be restructured to highlight how increasing substance misuse can worsen discomfort from common medical symptoms in the short term, as well as how these worsening symptoms could exacerbate social embarrassment or decrease physical attractiveness.
Digital Interventions to Support Adolescents and Young Adults With Cancer: Systematic Review
Authors: McCann Lisa , McMillan Kathryn Anne , Pugh Gemma
Published: November 2019

Background

The last decade has seen an increase in the number of digital health interventions designed to support adolescents and young adults (AYAs) with cancer.

Objective

The objective of this review was to identify, characterize, and fully assess the quality, feasibility, and efficacy of existing digital health interventions developed specifically for AYAs, aged between 13 and 39 years, living with or beyond a cancer diagnosis.

Methods

Searches were performed in PubMed, EMBASE, and Web of Science to identify digital health interventions designed specifically for AYA living with or beyond a cancer diagnosis. Data on the characteristics and outcomes of each intervention were synthesized.

Results

A total of 4731 intervention studies were identified through the searches; 38 interventions (43 research papers) met the inclusion criteria. Most (20/38, 53%) were website-based interventions. Most studies focused on symptom management and medication adherence (15, 39%), behavior change (15, 39%), self-care (8, 21%), and emotional health (7, 18%). Most digital health interventions included multiple automated and communicative functions such as enriched information environments, automated follow-up messages, and access to peer support. Where reported (20, 53% of studies), AYAs’ subjective experience of using the digital platform was typically positive. The overall quality of the studies was found to be good (mean Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields scores >68%). Some studies reported feasibility outcomes (uptake, acceptability, and attrition) but were not sufficiently powered to comment on intervention effects.

Conclusions

Numerous digital interventions have been developed and designed to support young people living with and beyond a diagnosis of cancer. However, many of these interventions have yet to be deployed, implemented, and evaluated at scale.
Antimicrobial Resistance of Neisseria Gonorrhoeae in a Newly Implemented Surveillance Program in Uganda: Surveillance Report (Preprint)

Published: November 2019

BACKGROUND

Neisseria gonorrhoeae (commonly known as gonorrhea) has developed resistance to all first-line therapy in Southeast Asia. East Africa has historically had absent or rudimentary gonorrhea surveillance programs and, while the existence of antimicrobial-resistant gonorrhea is recognized, the extent of its resistance is largely unknown. In 2016, the World Health Organization’s Enhanced Gonococcal Antimicrobial Surveillance Program (EGASP) was initiated in Uganda to monitor resistance trends.

OBJECTIVE

This study characterizes gonorrhea and antibiotic resistance in a large surveillance program of men with urethral discharge syndrome from Kampala, Uganda.

METHODS

Men attending sentinel clinics with urethritis provided demographic information, behavior data, and a urethral swab in line with the World Health Organization’s EGASP protocols for culture, identification, and antibiotic-sensitivity testing using 2 methods—disk diffusion (Kirby-Bauer test) and Etest (BioMérieux Inc). A subset of samples underwent detailed antimicrobial resistance testing.

RESULTS

Of 639 samples collected from September 2016 to February 2018, 400 (62.6%) were culture-positive though 414 (64.8%) had microscopic evidence of gonorrhea. The mean age of the men from whom the samples were collected was 26.9 (SD 9.6) years and 7.2% (46/639) reported having HIV. There was high-level resistance to ciprofloxacin, tetracycline, and penicillin (greater than 90%) by Kirby-Bauer disk diffusion and 2.1% (4/188) had reduced azithromycin sensitivity by Etest. Of the early isolates that underwent detailed characterization, 60.3% (70/116) were culture-positive, 94% (66/69) isolates were either ciprofloxacin-resistant or ciprofloxacin-intermediate by Etest, 96% (65/68) were azithromycin-sensitive, and 96% (66/69) were gentamicin-sensitive. Resistance profiles were comparable between methods except for ceftriaxone (disk diffusion: 68/69, 99%; Etest: 67/69, 97%) and for gentamicin (disk diffusion: 2/8, 25%; Etest: 66/69, 96%) sensitivity.

CONCLUSIONS

This is the first report from a systematic gonorrhea surveillance program in Uganda. Findings demonstrated resistance or increased minimum inhibitory concentration to all key antigonococcal antibiotics. There was evidence of poor antibiotic stewardship, near-universal resistance to several antibiotics, and emerging resistance to others. Individuals in the population sampled were at exceptionally high risk of STI and HIV infection requiring intervention. Ongoing surveillance efforts to develop interventions to curtail antimicrobial-resistant gonorrhea are needed.
Costing and Cost-Effectiveness of a Mobile Health Intervention (ImTeCHO) in Improving Infant Mortality in Tribal Areas of Gujarat, India: Cluster Randomized Controlled Trial (Preprint)
Authors: Modi Dhiren , Saha Somen , Vaghela Prakash , Dave Kapilkumar , Anand Ankit , Desai Shrey , Shah Pankaj
Published: November 2019

BACKGROUND

During 2013, a mobile health (mHealth) program, Innovative Mobile Technology for Community Health Operation (ImTeCHO), was launched in predominantly tribal and rural communities of Gujarat, India. ImTeCHO was developed as a job aid for Accredited Social Health Activists (ASHAs) and staff of primary health centers to increase coverage of maternal, neonatal, and child health care.

OBJECTIVE

In this study, we assessed the incremental cost per life-years saved as a result of the ImTeCHO intervention as compared to routine maternal, neonatal, and child health care programs.

METHODS

A two-arm, parallel, stratified cluster randomized trial with 11 clusters (primary health centers) randomly allocated to the intervention (280 ASHAs, n=2,34,134) and control (281 ASHAs, n=2,42,809) arms was initiated in 2015 in a predominantly tribal and rural community of Gujarat. A system of surveillance assessed all live births and infant deaths in the intervention and control areas. All costs, including those required during the start-up and implementation phases, were estimated from a program perspective. Incremental cost-effectiveness ratios were estimated by dividing the incremental cost of the intervention with the number of deaths averted to estimate the cost per infant death averted. This was further analyzed to estimate the cost per life-years saved for the purpose of comparability. Sensitivity analysis was undertaken to account for parameter uncertainties.

RESULTS

Out of a total of 5754 live births (3014 in the intervention arm, 2740 in the control arm) reported in the study area, per protocol analysis showed that the implementation of ImTeCHO resulted in saving 11 infant deaths per 1000 live births in the study area at an annual incremental cost of US $163,841, which is equivalent to US $54,360 per 1000 live births. Overall, ImTeCHO is a cost-effective intervention from a program perspective at an incremental cost of US $74 per life-years saved or US $5057 per death averted. In a realistic environment with district scale-up, the program is expected to become even more cost-effective.

CONCLUSIONS

Overall, the findings of our study strongly suggest that the mHealth intervention as part of the ImTeCHO program is cost-effective and should be considered for replication elsewhere in India.

Development of a National Caregiver Health Survey for Hematopoietic Stem Cell Transplant: Qualitative Study of Cognitive Interviews and Verbal Probing (Preprint)
Authors: Kedroske Jacob , Koblick Sarah , Chaar Dima , Mazzoli Amanda , O'Brien Maureen , Yahng Lilian , Vue Rebecca , Chappell Grant , Shin Ji Youn , Hanauer David A , Choi Sung Won
Published: November 2019

BACKGROUND

Roadmap 1.0 is a mobile health app that was previously developed for caregivers of patients who have undergone hematopoietic stem cell transplantation (HSCT). Formative research targeted toward its end users (caregivers) can help inform app design and development, allowing additional components to be incorporated into the app, which can then be tested in a future randomized controlled trial.

OBJECTIVE

This study aimed to create a methodologically rigorous national survey that would help inform the development of Roadmap 2.0.

METHODS

We conducted a prospective, qualitative research study that took place between November 18, 2018, and February 7, 2019, in a blood and marrow transplant unit within a large academic medical institution in the midwestern part of the United States. Cognitive interviews, including think-aloud and verbal probing techniques, were conducted in 10 adult caregivers (≥18 years) of patients who had undergone HSCT.

RESULTS

Most participants were female (9/10, 90%), white (9/10, 90%), married (9/10, 90%), employed at least part time (6/10, 60%), caregivers of adult patients (7/10, 70%), and had some college education (9/10, 90%) and an annual household income of $60,000 or higher (6/10, 60%). All but one interview was audio-recorded, with permission. Overall, participants were engaged in the cognitive interview process of the draft survey, which included 7 topics. The interviews highlighted areas wherein survey items could be further refined, such as offering more response choices (eg, “NA”) or clarifying the type of transplant (eg, autologous or allogeneic) or context of transplant care (eg, pre-HSCT, during HSCT, post-HSCT, inpatient, and outpatient). Apart from these findings, the items in demographics, caregiving experiences, technology, positive activities, and mood were generally interpreted as intended. On the basis of the transcript data and field notes by the interviewer, items within self-efficacy (Caregiver Self-Efficacy Scale) and coping (Brief Coping Orientation to Problems Experienced inventory) questionnaires generated more confusion among interviewer and participants, reflecting difficulties in interpreting the meaning of some survey items.

CONCLUSIONS

This study incorporated the four cognitive aspects of survey methodology that describe the question-answering process—(1) comprehension, (2) information retrieval, (3) judgment and decision making, and (4) responding—by using the think-aloud and probing techniques in cognitive interviews. We conclude that this methodologically rigorous process informed revisions and improved our final questionnaire design.

Published: November 2019

BACKGROUND

There are over 2 million newly diagnosed patients with breast cancer worldwide with more than 10,000 cases in Taiwan each year. During 2017-2018, the National Yang-Ming University, the Taiwan University of Science and Technology, and the Taiwan Breast Cancer Prevention Foundation collaborated to develop a breast cancer self-management support (BCSMS) mHealth app for Taiwanese women with breast cancer.

OBJECTIVE

The aim of this study was to investigate the quality of life (QoL) of women with breast cancer in Taiwan after using the BCSMS app.

METHODS

After receiving a first diagnosis of breast cancer, women with stage 0 to III breast cancer, who were recruited from social networking sites or referred by their oncologists or oncology case managers, were randomized 1:1 into intervention and control groups. Intervention group subjects used the BCSMS app and the control group subjects received usual care. Two questionnaires—the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire Core 30 (QLQ-C30) and the EORTC Breast Cancer-Specific Quality-of-Life Questionnaire (QLQ-BR23)—were distributed to subjects in both arms. Paper-based questionnaires were used at baseline; paper-based or Web-based questionnaires were used at 1.5-month and 3-month follow-up evaluations. All evaluations were self-assessed and anonymous, and participants were blinded to their allocation groups. Descriptive analysis, the Pearson chi-square test, analysis of variance, and the generalized estimating equation were used to analyze the data. Missing values, with and without multi-imputation techniques, were used for sensitivity analysis.

RESULTS

A total of 112 women were enrolled and randomly allocated to either the experimental group (n=53) or control group (n=59). The follow-up completion rate was 89.3% (100/112). The demographic data showed homogeneity between the two groups in age (range 50-64 years), breast cancer stage (stage II), marital status (married), working status (employed), and treatment status (receiving treatments). The mean total QoL summary scores from the QLQ-C30 (83.45 vs 82.23, P=.03) and the QLQ-BR23 (65.53 vs 63.13, P=.04) were significantly higher among the experimental group versus the control group, respectively, at 3 months.

CONCLUSIONS

This research provides support for using a mobile health care app to promote the QoL among women in Taiwan after a first diagnosis of breast cancer. The BCSMS app could be used to support disease self-management, and further evaluation of whether QoL is sustained is warranted.

Purpose: To compare nutritional habits, physical function and psychological constructs between Costa Rican older adults from urban and rural zones.Methods: Male and female older adults aged ? 65 yr. from urban (n = 185) and rural (n = 109) Costa Rica were assessed on nutritional habits, physical function measures, and cognitive function by a face-to-face interview.Results: Rural older adults consumed more daily carbohydrates, protein, and energy at breakfast and lunch (p < 0.05 for all), and more carbohydrates (p ? 0.001), fat (p = 0.002), protein (p ? 0.001), and energy (p ? 0.001) at dinner than urban elderly. Aerobic power (p = 0.044) was higher in urban compared to rural elderly. A correlation was found between aerobic power and global fatigue (r = -0.20, p = 0.014) in urban elderly. Lifetime cognitive activity correlated to total energy (r = 0.37, p = 0.003), carbohydrate (r = 0.37, p = 0.002), and protein (r = 0.34, p = 0.005) consumption in rural elderly. Higher depression scores (p = 0.048), and lower lifetime cognitive activity were observed in urban compared to rural elderly (p = 0.004).Conclusion: The health profile is positive for either group depending on the variable analyzed, except for a higher aerobic power, which provides benefits to the entire cohort.

Urbano cindido: tensões da metrópole em AU3 – Autopista Central
Authors: Goulart Marilia-Marie
Published: November 2019

Inserido no campo das artes visuais, o cinema pode ser definido como uma prática arquitetônica, como um agente na construção das visões das cidades. Mais do que ser o local onde transcorre a ação, os espaços fílmicos podem ser trabalhados como elementos potentes para descortinar o passado, trazendo à tona memórias e dinâmicas menos explícitas, fazendo ver e ouvir processos que a narrativa oficial buscou ocultar. Com sensibilidade, a construção espacial do documentário AU3 – Autopista Central (Alejandro Hartmann, 2010) coloca em cena a tensão social e urbana que atravessam diferentes períodos da história de Buenos Aires. Através do olhar atento aos espaços e moradores de Villa Urquiza, AU3 confere visibilidade aos processos de exclusão da cidade e também à inominável violência da ditadura, oferecendo uma mirada contra a tentativa de apagar narrativas indesejadas à história oficial.

IN VITRO DISSOLUTION STUDY OF GLIMEPIRIDE FROM BINARY AND TERNARY SOLID DISPERSION FORMULATION
Authors: Akhter Sharmin , Hossen Md. Sajjad , Salahuddin Md. , Sunny Muazzem Ahmed , Sathi Farzana Akther , Islam Md. Shahidul
Published: November 2019

Glimepiride (GMP) is poorly water soluble drug, so solubility is the main constraint for its oral bioavailability. Because, poor aqueous solubility and slow dissolution rate of the glimepiride lead to irreproducible clinical response or therapeutic failure in some cases due to sub therapeutic plasma drug levels. In this study, binary and ternary solid dispersion of glimepiride were prepared with polyethylene glycol 6000 (PEG 6000) and polyethylene glycol 4000 (PEG 4000) at different weight ratios using the solvent evaporation and melting method. It was found the drug was released 0.46% after 5 minutes and only 15.83% within 60 minutes from active glimepiride on the other hand the release pattern of glimepiride from the binary formulation containing PEG 4000 in 1:5 (Formulation coding: G5) showed the best result. It was found that the ternary different SD formulation containing(PEG4000:Glimepiride:Povidone) In ratio 1:1:0.25 (Formulation coding were : G13) showed the best result. The drug was changed to amorphous form after solid dispersion. Itwas also evident that solid dispersions improve solubility of drug particles thus enhancing dissolution characteristics of drugs they increase the oral bioavailability.
Peer Review History:
UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

A practical technique for preserving specimens of duckmeal, Wolffia (Araceae)
Authors: Brunton Daniel F.
Published: November 2019

Making identifiable herbarium vouchers of the minute aquatic vascular plant duckmeal, Wolffia (Lemnoideae; Araceae) has typically required plants to be preserved in transparent, space-consuming vials that are fragile, difficult to work with, and labourious to prepare. An alternative technique for dry-mounting Wolffia within a layer of transparent, acid-free glue presents a promising alternative. Although the largely water-filled individual plants still compress substantially, this preparation technique results in specimens that retain their colour, size, and, most important, their shape. This greatly enhances the possibility of confident identification and simplifies both specimen preparation and storage.

Published: November 2019

The aim of this study was to determine the effect of aluminablasting on the bond durability of universal adhesives and adherent surface characteristics. Adhese Universal (Ivoclar Vivadent), All-Bond Universal (Bisco), Bondmer Lightless (Tokuyama Dental), G-Premio Bond (GC), and Scotchbond Universal (3M ESPE) were used in self-etch mode. The prepared bovine enamel and dentin specimens were divided into two groups based on whether they received an aluminablasting prior to application of the universal adhesives. The resin composite bonded specimens were stored in distilled water at 37°C for 24 hours, following which the shear bond strength (SBS) of half of the specimens was measured (24-hour group). The other half was subjected to 30,000 thermal cycles between 5 and 55°C before SBS measurement (TC group). Surface roughness (Ra) and surface free energy (SFE) of the adherent surfaces were also measured, and scanning electron microscopy observation and scanning electron microscopy/energy-dispersive X-ray analysis were carried out. Most of the adhesives did not show any significant differences in enamel SBS values between the two pretreatment groups, regardless of the storage condition. However, the dentin SBS values were significantly lower in specimens that underwent aluminablasting compared with those that did not, irrespective of their storage conditions. Significantly higher Ra and SFE values were observed in the enamel and dentin of specimens that underwent aluminablasting. Although aluminablasting increased the Ra and SFE values of enamel and dentin, its effect on the SBS value was dependent on the tooth substrate. In addition to C, O, Na, Mg, P, and Ca, the element Al was detected in the enamel and dentin of samples that had undergone aluminablasting. These results suggest that although aluminablasting of the tooth surface is thought to be effective for modification of the adherent surface, it may not enhance enamel bond performance and may also adversely affect the dentin bond effectiveness of the universal adhesives.

O cinema de animação estabeleceu, desde os seus primórdios, um compromisso com os espectadores: estimular a sua imaginação. Fugindo à representação óbvia do mundo e cortejando a fantasia, a animação evoluiu lado a lado com o cinema para gestos e olhares cada vez mais complexos e diversificados sobre a realidade. Afirmava o cineasta português João Mário Grilo, durante uma aula de realização cinematográfica por si lecionada, que “o cinema é a construção de um olhar”. Um olhar atento sobre o mundo e sobre as pessoas. Um olhar multidimensional, construído pela relação entre autor, espectador, personagem e o próprio cinema. Um olhar honesto lançado ao primeiro toque do lápis no papel, da mão a envolver a plasticina, da agulha sobre o acetato, do dedo a empurrar o alfinete… Um olhar que desafia o espectador a mergulhar nas imagens e tomar consciência daquilo que simbolizam.

Authors: Eiada Rabab Reda , Badran Ebrahim A. , Mansy Ibrahim I. I.
Published: November 2019

The power disturbances in the transmission system can be controlled and reduced by using unified power flow controller (UPFC). UPFC is used for controlling power flow in electrical transmission system. In this paper an algorithm for optimizing and smart controlling of UPFC, using an artificial neural network controller (ANNC) and a Binary Particle Swarm Optimization (BPSO), is proposed for smarting transmission system. The proposed algorithm controls the parameters of the UPFC. Therefore, a best performance of the UPFC is achieved and the transmission losses are minimized at different load conditions and variation of generation.  Matlab is used for simulating the proposed algorithm and the test system. The results show that the UPFC using the proposed algorithm effectively act the proposed requirements.
