На основе анализа факторов, оказывающих влияние на долговечность работы технологического оборудования промышленных предприятий, показана роль научно обоснованной системы планирования как функции управления техническим обслуживанием и ремонтом оборудования. Показано, что применение системы планово-предупредительного ремонта позволяет подготовить управляемую и прогнозируемую на длительный период ремонтную программу по видам ремонтов, типам оборудования, цехам и предприятию в целом; прогнозировать материальные, финансовые и трудовые ресурсы, необходимые капитальные вложения в развитие производственной базы ремонтной службы; осуществить предварительную подготовку ремонтных работ, выполнять их в минимальные сроки; повышает качество ремонта и, в конечном итоге, увеличивает надежность работы оборудования. Однако существующий уровень планирования технического обслуживания и ремонта оборудования не всегда отвечает стоящим задачам, поскольку используются устаревшие нормы и нормативы, разработанные еще в период командно-административной системы, не учитывающие технологические, материальные, временные, трудовые ограничения и зачастую устанавливаемые на основе достигнутого в отчетном периоде уровня и сложившейся динамики. Применение цифровых технологий предприятиями традиционного уклада, использующими современные технологии в качестве своей инфраструктуры, открывает возможности устранения несовершенства существующей информационной базы планирования и производства ремонтных работ и услуг на предприятии. Для этого необходимо провести исследования износостойкости групп сопрягаемых деталей (вал - втулка, винт - гайка, трущиеся плоскости) по типам технологического оборудования, размерам, точности обработки, видам материалов при различных скоростных режимах. Задача архисложная, но решение проблемы позволит реализовать упреждающее планирование и осуществление ремонтных воздействий с целью предупреждения аварийных ситуаций.
Geoinformation Mapping Through the Types of Geological and Geomorphological Structure of the Katun Valley (Altay Mountains) Based on Morphometric Indicators
Authors: Kotler S.A. , Zolnikov I.D. , Pchelnikov D.V.
Published: October 2018

The types of geological and geomorphological structure of the Katun valley are distinguished in the work. For this, a method of geoinformation mapping using morphometric indicators of the valley’s width and meandering of the channel was developed. The morphometric parameter of the valley’s width was calculated as the total area of terraces. As the morphometric parameters of the channel’s meandering, the angles of the river segments’ deviation relative to each other were calculated. Conjugated analysis of these morphometric indicators enabled identifying 18 morphotypes. These morphotypes according to the geological and geomorphological structure of the valley were combined into 4 classes. Separation of the Katun valley in certain classes and morphotypes is due to the different geological history of these sites during the Quaternary period. The most important reasons predetermining the modern variety of geological and geomorphological types of the valley are neotectonic movements and exogenous phenomena (glaciers, dam lakes, landslides, etc.) naturally localized in the space from the upstream of the river to its exit into the foothills. The developed method can be applied for quantitative morphometric classification of the mountain rivers’ valleys in other regions.

Side-stream sludge treatment using free ammonia for reducing sludge production
Authors: Song Kang , Zhou Xu , Zhou Yi-Wen , Jin Wenbiao , Tu Renjie
Published: October 2018

Much attention has been paid to reducing of excess sludge production in the activated sludge process, due to high treatment and disposal costs. In this study, an innovative approach for achieving sludge reduction, which featured recirculating a portion of the activated sludge through a side-stream sludge treatment unit, was applied by adding free ammonia (FA, i.e., NH3). The results showed that sludge production was significantly reduced after FA treatment, while the sludge production rate was decreased by 21%. Meanwhile, the treatment performance and the sludge properties were not negatively affected by the FA-treated sludge during the experiment (e.g. effluent quality, nitrification activity, sludge settleability). Economic analysis also indicated that the FA treatment approach would be an economically favorable technology, and the sludge treatment costs could be cut by 16.6%.
The influence of combined active fillers on the properties of elastomeric materials for eco-friendly tyres

Published: October 2018

Reinforcing of elastomers by the addition of various nanofillers has led to
significant improvements in elastomer properties, and therefore, to the
increase of potentials for use as suitable materials for special
applications. The aim of this study was to investigate the effects of
combinations of two active fillers (carbon black and synthesized silica
(50/0; 35/15; 25/25; 15/35; 0/50; phr)) on the morphology, curing, as well
as thermal, dynamic-mechanical and mechanical properties of nanocomposites
based on the styrene-butadiene rubber as the network precursor. Based on SEM
results, the largest agglomerates were observed in the structure of the
nanocomposite containing 25 phr of carbon black and 25 phr of SiO2.
Determination of curing characteristics indicated that the minimum torque at
100, 150 and 160?C had higher magnitudes for the compounds with silica
filler, which is in accordance with the tendency of SiO2 to form
filler-filler interactions. Values of the scorch time and the optimal time
of crosslinking increased by increasing the silica phr content in the
fillers mixture. It could be thus supposed that the fraction of occluded and
trapped chains in the structure of elastomer reinforced by SiO2 is higher
due to the almost 2-fold higher value of the silica NDBP number as compared
to the NDBP number of carbon black particles. On the basis of MDSC results,
it was assessed that the addition of combined active fillers had negligible
effects on the glass transition temperature, registered at about -47?C for
all tested samples. The obtained DMA data, concerning storage moduli in the
temperature range from -20 to 0?C, (characteristic for "Payne" effect) are
very significant for predictions of the properties of the tyre tread such as
the slip resistance on the road on ice and in the wet conditions. The
increase of silica content in the combined filler induced a decrease of the
dynamic mechanical loss factor of prepared nanocomposites in the temperature
range from 40 to 80?C. The obtained results are very important for the
structuring of elastomeric materials aimed for production of tyres with
reduced rolling resistance and fuel consumption. The elastomer containing
the highest content of carbon black showed the highest value of the tensile
strength (21.8 MPa). The abrasion resistance of the synthesized
nanocomposites increased as the silica content was reduced in the combined
fillers.
Modeling the water side corrosion and hydrogen pickup of VVER 1000 fuel clad
Authors: Ramezani Leila , Mansouri Masoud , Rahgoshay Mohammad
Published: October 2018

Zirconium alloys, are usually used as fuel cladding materials in VVER (water-cooled, water-moderated energy reactor) type reactors, mainly, due to their low neutron absorption cross-section, desirable mechanical properties, and good corrosion resistance under reactor operating conditions. During exposure to water at high temperature, water reacts with zirconium alloys, which results in the production of an oxide layer. The entire area of corrosion along with the accompanying absorption of hydrogen in the zirconium metal matrix has attracted a lot of attention when the performance of the core components as well as the operation of the reactor is emphasized. The growth of the zirconium oxide layer plays a destructive role in decreasing thermal efficiency of the reactor by restricting the inlet temperature and chemical properties of the coolant. The present study aimed to develop a computer code to predict long-term water side corrosion weight gain, oxide thickness and determine the concentration of absorbed hydrogen in VVER-1000 reactors during normal operating conditions. The proposed model can be utilized to estimate the pre-transition and post-transition corrosion weight gain and the oxide thickness in operating conditions.

Published: October 2018

Background/Aim. Consensus on the exercise effect on the fatty acid metabolism has not been reached, and probably depends on the type of sports (aerobic, anaerobic or mixed). The aim of this study was to investigate effect of long-term handball training on the body composition, lipid profile and the plasma phospholipid fatty acid composition in female and male younger players. Methods. Seventeen female and 15 male active handball players, aged 16?20 years, who competed at the national/international level, were enrolled in the study. A control group was established from healthy, sedentary individuals (13 females and 19 males, aged 17?21 years), comparable to the athletes in terms of age, sex and body mass index. Results. In both groups of handball players a higher percentage of palmitoleic acid and alpha linolenic acid (18:3, n-3), were found and lower percentage of oleic acid and docosahexaenoic acid (22:6, n-3), when compared with corresponding control group. On the other hand, the lower level of stearic acid and estimated activity of plasma elongase was detected in female players than in sedentary women. Furthermore, higher proportion of linoleic acid (18:2, n-6), n-6 polyunsaturated fatty acids (PUFA) and total PUFA was found only in female players in comparison to the control group. Conclusion. The observed differences between handball players and sedentary individuals showed that handball training influenced lipid and fatty acid metabolism. Follow-up of these changes could indicate potential need for supplementation or nutritional intervention in young handball players.
Third molar tooth agenesis and pattern of impaction in patients with palatally displaced canines
Authors: Alhaija Elham S. Abu , Wazwaz Fedaa T.
Published: October 2018

Objectives:

To investigate the association between third molar agenesis and pattern of impaction, missing teeth, and peg-shaped lateral incisor with palatal canine displacement (PDC).

Materials and Methods:

The pretreatment orthodontic orthopantomograms of 438 patients (122 males and 316 females) diagnosed with PDC were included. A total of 338 patients with normally erupted canines who had a preexisting radiograph as part of their orthodontic treatment (125 males and 313 females) served as controls. Orthopantomograms were evaluated for missing third molars, third molar eruption status, and type of impaction, third molar spaces, third molar width, and angulation.

Results:

In the PDC group, at least one third molar was missing in 48% and 19% in the upper and lower arches, respectively. Also, 38% and 67% of PDC patients had at least one third molar impaction in the upper and lower arches, respectively. The difference between the PDC and control groups was significant for both missing and impacted third molars (P < .001 for each). The most common type of third molar impaction in the upper arch was vertical and distoangular in the PDC and control groups, respectively. Upper and lower third molar width and spaces were reduced in PDC patients when compared with the control group (P < .001). In PDC patients, missing teeth and peg-shaped lateral incisors were recorded in 5.6% and 9.1%, respectively.

Conclusions:

PDC patients showed a high prevalence of third molar agenesis and impaction. Upper and lower third molar width and space were reduced in the PDC patients. There were no significant associations between tooth agenesis (other than third molars) and the PDC anomaly.
Long-term follow-up of camouflage effects following resin infiltration of post orthodontic white-spot lesions in vivo
Authors: Knösel Michael , Eckstein Amely , Helms Hans-Joachim
Published: October 2018

Objectives:

To reassess the long-term camouflage effects of resin infiltration (Icon, DMG, Hamburg, Germany) of white spot lesions (WSL) and sound adjacent enamel (SAE) achieved in a previous trial. The null hypothesis was tested that there were no significantly different CIE-L*a*b*-ΔE-values between WSL and SAE areas of assessment after at least 24 months (T24) compared to those at baseline (T0).

Materials and Methods:

Of twenty subjects who received previous resin infiltration treatment of nteeth = 111 nonrestored, noncavitated postorthodontic WSL after multibracket treatment during a randomized controlled trial and were contacted 20 months after baseline, eight subjects (trial teeth nteeth = 40; m/f ratio 1/7; age range (mean; SD) 12–17 [15.25; 2.12] years); response rate: 40%) were available for follow-up after at least 24 months (T24). CIE-L*a*b* differences between summarized color and lightness values (ΔEWSL/SAE) of WSL and SAE were assessed using a spectrophotometer and compared to baseline data assessed prior to infiltration (T0), and those after 6 (T6), and 12 (T12) months using paired t tests at a significance level of α = 5%.

Results:

T24 assessments were performed after a mean 33.86 (SD: 8.64; Min: 24; Max: 45) months following T0. Mean (SD) ΔEWSL/SAE units of available teeth were 8.76 (5.33) at baseline; 5.5 (2.75) at T6; 5.2 (2.41) at T12; and 5.57 (2.6) at T24. Comparisons of T6, T12, and T24 with T0 yielded highly significant differences, whereas T6–T24 and T12–T24 differences were found to be not significant.

Conclusions:

Assimilation of infiltrated WSL to the color of adjacent enamel by resin infiltration is considered to be suitable for the long-term improvement in the esthetic appearance of postorthodontic WSL.

Published: October 2018

The impact of glycemic variability on brain glucose transport kinetics among individuals with type 1 diabetes mellitus (T1DM) remains unclear. Fourteen individuals with T1DM (age 35 ± 4 years; BMI 26.0 ± 1.4 kg/m2; HbA1c 7.6 ± 0.3) and nine healthy control participants (age 32 ± 4; BMI 23.1 ± 0.8; HbA1c 5.0 ± 0.1) wore a continuous glucose monitor (Dexcom) to measure hypoglycemia, hyperglycemia, and glycemic variability for 5 days followed by 1H MRS scanning in the occipital lobe to measure the change in intracerebral glucose levels during a 2-h glucose clamp (target glucose concentration 220 mg/dL). Hyperglycemic clamps were also performed in a rat model of T1DM to assess regional differences in brain glucose transport and metabolism. Despite a similar change in plasma glucose levels during the hyperglycemic clamp, individuals with T1DM had significantly smaller increments in intracerebral glucose levels (P = 0.0002). Moreover, among individuals with T1DM, the change in brain glucose correlated positively with the lability index (r = 0.67, P = 0.006). Consistent with findings in humans, streptozotocin-treated rats had lower brain glucose levels in the cortex, hippocampus, and striatum compared with control rats. These findings that glycemic variability is associated with brain glucose levels highlight the need for future studies to investigate the impact of glycemic variability on brain glucose kinetics.

OBJECTIVE

Specific lipid molecular changes leading to type 2 diabetes (T2D) are largely unknown. We assessed lipidome factors associated with future occurrence of T2D in a population at high cardiovascular risk.

RESEARCH DESIGN AND METHODS

We conducted a case-cohort study nested within the PREDIMED trial, with 250 incident T2D cases diagnosed during 3.8 years of median follow-up, and a random sample of 692 participants (639 noncases and 53 overlapping cases) without T2D at baseline. We repeatedly measured 207 plasma known lipid metabolites at baseline and after 1 year of follow-up. We built combined factors of lipid species using principal component analysis and assessed the association between these lipid factors (or their 1-year changes) and T2D incidence.

RESULTS

Baseline lysophosphatidylcholines and lysophosphatidylethanolamines (lysophospholipids [LPs]), phosphatidylcholine-plasmalogens (PC-PLs), sphingomyelins (SMs), and cholesterol esters (CEs) were inversely associated with risk of T2D (multivariable-adjusted P for linear trend ≤0.001 for all). Baseline triacylglycerols (TAGs), diacylglycerols (DAGs), and phosphatidylethanolamines (PEs) were positively associated with T2D risk (multivariable-adjusted P for linear trend <0.001 for all). One-year changes in these lipids showed associations in similar directions but were not significant after adjustment for baseline levels. TAGs with odd-chain fatty acids showed inverse associations with T2D after adjusting for total TAGs.

CONCLUSIONS

Two plasma lipid profiles made up of different lipid classes were found to be associated with T2D in participants at high cardiovascular risk. A profile including LPs, PC-PLs, SMs, and CEs was associated with lower T2D risk. Another profile composed of TAGs, DAGs, and PEs was associated with higher T2D risk.

Published: October 2018

El objetivo de la presente investigación fue conocer, a través de foros presenciales, la opinión de un grupo egresados de la licenciatura en Idiomas de la Universidad Juárez Autónoma de Tabasco (UJAT) sobre las competencias, habilidades y actitudes que tendrían que dominar los futuros profesionales de esa especialidad para desempeñarse con éxito en el mercado laboral. Para elegir a los participantes se realizó una convocatoria, a la cual acudieron 37 egresados que en ese momento se encontraban trabajando en distintas instituciones de la región. Los resultados demuestran que a muchos aún les cuesta dominar los tres idiomas que conforman su área de estudio (inglés, francés e italiano), por lo que consideran que en la carrera se deben diseñar más actividades prácticas y promover la actualización constante de los docentes de las distintas cátedras.

Get off my land! Towards mutual understanding in archaeological field conflicts
Authors: Mapunda Bertram
Published: October 2018

Genuine community participation in research and conservation projects is crucial for sustainable protection, management and development of archaeological sites, especially in sub-Saharan Africa where the scientific value of such resources is less appreciated. Local people often become suspicious of and discontented with field researchers who do not inform them of what they are doing around their courtyard, just as they are displeased with government officials who impose conservation projects upon them. Their discontent often comes for good reasons: either the given research or project is not a priority to them or its objectives differ from theirs. As a result, a conflict of expectations emerges, often leading local communities into disliking the project and hence investing little or just superficial commitment to it. Such feelings may be expressed verbally in formal or informal gatherings or through indifference, resentment, or vandalism, all of which are detrimental to the proper management of the heritage resource in question. Using specific cases of researchers/administrators-villagers differences and conflicts of expectations experienced in various places in Tanzania, the paper discusses causes of such differences, critically examines the Community Participatory technique exposing its strengths and weaknesses, as well as suggests solutions and outlining potential benefits should villagers be genuinely incorporated in such undertakings.

Digging up memories: Collaborations between archaeology and oral history to investigate the industrial housing experience
Authors: Massheder-Rigby Kerry
Published: October 2018

This paper forms part of a wider PhD project exploring whether there can be an informative research relationship between archaeology and oral history. Its focus is on the working class housing experience in the North of England during the Industrial Revolution period. Oral history as a discipline applied within archaeological investigation is growing in popularity and in application in the UK as a form of ‘community archaeology’. Evidence suggests that there is potential for combining the memories of oral history testimonies and the physical archaeological evidence from excavation to enhance our understanding of an event, person, time and place. However, establishing what evidence of the housing experience survives in an archaeological context and what survives in memory is crucial to the success of a combined investigative approach. This paper will use the example of The Public Archaeology Programme of the site Dixon’s Blazes as a relevant example in which to explore this, with evidence of sanitation, overcrowding and architecture surviving in both.
Decentering the discipline? Archaeology, museums and social media
Authors: Walker Dominic
Published: October 2018

In recent years archaeologists have asserted the value of social media for achieving goals such as ‘shared authority’ and the ‘empowerment’ of various communities. These assertions often resemble techno-utopian discourse. However, it is essential to critically consider these assertions with reference to the important studies emerging from the fields of new media studies and Indigenous and collaborative archaeology, which have particularly emphasised the need for a greater awareness of sociopolitical contexts. Informed by this literature, this paper surveys some of the emerging and established uses of social media by archaeologists and museums, and proceeds to introduce factors that challenge the broadly positive discourses about the impact of social media on various communities. It also highlights the need for short- and long-term impact studies.
Local Communities’ Perceptions of Archaeology and Cultural Heritage Resources in the Mtwara Region of Tanzania
Authors: Gabriel Festo W.
Published: October 2018

This paper examines local communities’ understanding of archaeology and cultural heritage resources. This study was conducted among the Makonde communities of the Mtwara Region of south-eastern Tanzania. The paper presents and critically discusses local communities’ views upon the meaning of archaeology and cultural heritage resources in general. The study used community-based methods by use of interviews, archaeological ethnography and focus group discussions. The results of this study reveal that the local communities in the Mtwara Region are not aware of the meaning of archaeology regardless of the number of archaeological researches that have been conducted in the region. Their understanding of the past is very much confined to intangible cultural traditions which are inherited and practised from one generation to another. Some conclusions are provided which undoubtedly indicate that according to the local communities’ perceptions cultural heritage resources are mainly characterized by intangible cultural practices and beliefs. As this study unveils, in this case tangible heritage resources have less importance to the local communities. This is contrary to the professional or academic conceptions which provide a dual focus on conservation and protection of tangible cultural heritage resources. It is only very recently that we see some studies being conducted focusing on intangible cultural heritage resources.
Blogging about the End Times: Dealing with the Fringes of Archaeology
Authors: Normark Johan
Published: October 2018

The 2012-phenomenon is based on the idea that something important was expected to occur on December 21, 2012, a date associated with the ancient Maya Long Count calendar. Even though the date has passed, the overall phenomenon is unlikely to disappear because the dominant themes of the end of the world and/or a transformation of consciousness can be found in other ‘alternative’ histories. These non-academic histories are ultimately apocalyptic in nature. The 2012-phenomenon is also an example of an ‘incorporeal hyperobject’, i.e. an object widely distributed and repeated. It is not anchored in a specific time-space unit but it is manifested in many different corporeal objects. The 2012-phenomenon is different from the academic Mayanist incorporeal hyperobject because each of them uses different distinctions of what exists or not. These different objects cannot communicate directly in different media ecologies since different distinctions have formed each one. Hence, there can never be a sincere understanding of each camp. Only by perturbing another object can information be translated into meaning. The blog is such a medium that can affect incorporeal hyperobjects. This article discusses the way one blog has interacted with the 2012-phenomenon.
Punk, DIY, and Anarchy in Archaeological Thought and Practice
Authors: Morgan Colleen
Published: October 2018

Recent developments in archaeological thought and practice involve a seemingly disparate selection of ideas that can be collected and organized as contributing to an anti-authoritarian, “punk” archaeology. This includes the contemporary archaeology of punk rock, the DIY and punk ethos of archaeological labor practices and community involvement, and a growing interest in anarchist theory as a productive way to understand communities in the past. In this article, I provide a greater context to contemporary punk, DIY, and anarchist thought in academia, unpack these elements in regard to punk archaeology, and propose a practice of punk archaeology as a provocative and productive counter to fast capitalism and structural violence.

The aim of this article is to identify, document and analyse three participatory actions undertaken in Mexico. They offer an alternative ground for analysis and reflection, as they were conducted outside the control of the State, offering the possibility to use different methodologies that contain key elements to think about a reorganization of the existing relation between Institutions and society. Based on extremely simple principles of action (painting, sweeping and cooking) their effects can help reshape the value and use of archaeological heritage in Mexico.
“Oriental” Churches of Levant and Mesopotamia in Continuing Social Fragmentation
Authors: SARABIEV A. V.
Published: October 2018

In the present difficult circumstances in the Middle East, the position of the so-called Oriental Churches, which is united by the similarity of the liturgical language, the language of the patristic and historical heritage – Syriac, is indicative. The pre-Chalcedon faith confession of these Christians and their special Eastern church rites, despite the separation of the Uniate Catholic communities, gave them an identity that persists to this day. The fate of these ancient autochthonous Christian communities was formed not only in conditions of an alien and heterodox environment, but also in isolation, and even confrontation with the main branches of Christianity. Now, serious efforts are being made by them in the mainstream of the activities of world supra-church structures, primarily the World Council of Churches. A characteristic feature of these communities are relatively prosperous diasporal communities, which far exceed the number of co-religionists in their historical homeland, and therefore, an important part of the ministry of their church hierarchy has become diverse contacts with foreign dioceses. Moreover, against the backdrop of the rise of the national aspirations of the Kurds – their neighbors in the territories of historical settlement – the national argument often referring to the Aramaic or Assyrian origin is often used. The vulnerable position of the flock of these ancient but few communities in the Middle East forces them to seek material, and sometimes even political, support abroad. Russia is still using the resource of only inter-church relations, which once showed its inadequacy, but at the same time the development of cultural ties with these communities in their homeland, the financial recharge of these projects on a secular basis could also contribute to strengthening our country’s image in the Middle East. The implementation of cultural, scientific and educational initiatives to support “Oriental” communities could become additional direction for Russia’s fruitful participation in the fate of the region, could prevent fragmentation of the Middle Eastern societies, to improve the situation of these communities and to normalize interfaith relations in general.
Efficient Iris Recognition Management in Object-Related Databases
Authors: Alvez Carlos , Miranda Ernesto , Etchart Graciela , Ruiz Silvia
Published: October 2018

Biometric applications have grown significantly in recent years, particularly iris-based systems. In the present work, an extension of an Object Relational Database Management System for the integral management of a biometric system based on the human iris was presented. Although at present, there are many database extensions for different domains, in no case for biometric applications. The proposed extension includes both the extension of the type system and the definition of domain indexes for performance improvement. The aim of this work is to provide a tool that facilitates the development of biometric applications based on the iris feature. Its development is based on a reference architecture that includes both the management of images of the iris trait, its associated metadata and the necessary methods for both manipulation and queries. An implementation of the extension is performed for PostgreSQL DBMS, and SP-GiST framework is used in the implementation of a domain index. Experiments were carried out to evaluate the performance of the proposed index, which shows improvements in query execution times.
Artificial Bee Colony Algorithm Improved with Evolutionary Operators
Authors: Minetti Gabriela , Salto Carolina
Published: October 2018

In this paper, we design, implement, and analysis the replacement of the method to create new solutions in artificial bee colony algorithm by recombination operators, since the original method is similar to the recombination process used in evolutionary algorithms. For that purpose, we present a systematic investigation of the effect of using six different recombination operators for real-coded representations at the employed bee step. All the analysis is carried out using well known test problems. The experimental results suggest that the method to generate a new candidate food position plays an important role in the performance of the algorithm. Computational results and comparisons show that three of the six proposed algorithms are very competitive with the traditional bee colony algorithm.
Are GPUs Non-Green Computing Devices?
Authors: Pi Puig Martín , De Giusti Laura , Naiouf Marcelo
Published: October 2018

With energy consumption emerging as one of the biggest issues in the development of HPC (High Performance Computing) applications, the importance of detailed power-related research works becomes a priority. In the last years, GPU coprocessors have been increasingly used to accelerate many of these high-priced systems even though they are embedding millions of transistors on their chips delivering an immediate increase on power consumption necessities. This paper analyzes a set of applications from the Rodinia benchmark suite in terms of CPU and GPU performance and energy consumption. Specifically, it compares single-threaded and multi-threaded CPU versions with GPU implementations, and characterize the execution time, true instant power and average energy consumption to test the idea that GPUs are power-hungry computing devices.

New kind of Cu based paste for Si solar cells front contact formation
Authors: Musztyfaga-Staszuk Małgorzata , Major Łukasz , Putynkowski Grzegorz , Sypień Anna , Gawlińska Katarzyna , Panek Piotr , Zięba Paweł
Published: October 2018

Potential impact of copper replacing silver in the paste used for the front electrode fabrication in crystalline silicon solar cells was investigated. The copper was applied as a new CuXX component with about 2 wt.% to 6 wt.% share of XX modifier. The generated CuXX molecules were analyzed using transmission microscopy. Based on the commercial Du Pont PV19B paste, CuXX and XX materials, the new PV19B/CuXX paste with 51 wt.% share of Cu and the PV19B/XX paste with 51 wt.% share of XX only were developed. Comparative studies of the effect of the commercial PV19B paste made by DuPont Company, and the pastes with the CuXX component and with the modifier XX alone on the electrical parameters of solar cells produced on crystalline silicon were carried out. The solar cells were characterized by the current-voltage technique. As a final result, the Cz-Si solar cell with the 51 wt.% share of Cu in the front electrode having a series resistance of 0.551 Ω·cm2, an efficiency of 14.08 % and, what is more important, the fill factor of 0.716, was obtained. It is the best result ever obtained concerning direct Cu application for solar cells fabricated in thick-film technology.
Use of scanning area related multiple degradation profiles for AFM assessment of polystyrene/PC61BM nanocomposite surface deterioration
Authors: Sikora Andrzej , Moczała Magdalena , Boharewicz Bartosz
Published: October 2018

In this paper, we present a novel approach developed in order to increase the reliability and accuracy of AFM investigation of morphological changes in a nanocomposite due to exposure to the media causing its degradation. By precise sample positioning and repetitive determination of the roughness changes at specific spots, we were able to create space-related degradation profiles. As the multi-step experiment based on exposure/scanning cycle was performed, we were able to observe a unique response of investigated samples revealing spatial inhomogeneity of the material. In order to present the measurement methodology, we used polystyrene samples containing various quantities of PC61BM nanofiller (0 %, 5 %, 10 % and 20 % of mass proportion), which was exposed to 370 nm UV radiation. Obtained data can be recognized as specific fingerprints of investigated materials. The solution based on creation and analysis of degradation profiles can be particularly useful for diagnostics of nanomaterials and nanocomposites to test their resistance to various conditions.
Adolescents’ Misuse of Over-The-Counter Medications: The Need for Pharmacist-led Intervention
Authors: Abraham Olufunmilola , Chmielinski Jessica
Published: October 2018

Adolescents’ misuse of over-the-counter (OTC) medications is a growing patient safety concern, resulting in an alarming number of poisonings and emergency department visits. OTC medications are easily accessible and adolescents often have the misconception that these medications are safe, even at higher than recommended doses. Dextromethorphan and acetaminophen are the most common and frequently misused OTC medications among adolescents, with significantly dangerous health risks if used improperly. Pharmacists are critical to the provision of education on safe OTC medication use for adolescents and their family caregivers by leading and implementing relevant community-based interventions. Ideal channels in which to do this in the community are pharmacies and schools. It is challenging to gain the attention of adolescents and to engage them; methods that include innovative measures and initiatives may be the solution. Research is needed to determine how pharmacists can improve adolescents’ knowledge and safe use of OTC medications. Pharmacists must be supported through training and acquisition of expertise specific to adolescent engagement and education. The development of pharmacist-led educational interventions that are tailored for adolescents that address their limited OTC medication knowledge and raise awareness of safety risks associated with misuse is crucial to preventing and reducing this patient safety problem in the community.

The stress levels of parents of premature infants and related factors in Nenoatal Intensive Care Units
Authors: Çekin Burcu , Turan Türkan
Published: October 2018

The aim of this study is to determine the stress levels of parents whose premature baby are hospitalized in the neonatal intensive care unit (NICU) and to determine the factors affecting their stress. The study sample included 101 parents of premature babies in the NICU of a university hospital. Interviews were conducted with the parents. Additionally, the Parental Stress Scale: Neonatal Intensive Care Unit (PSS:NICU) was administered. When the stress levels of parents in the NICU were analyzed, it was found that their scores on the infant`s appearance and behaviors subscale of the PSS:NICU reflected the highest rate of stress. The mean score on the parental role alterations subscale was higher among mothers than fathers (p < 0.05). Additionally, high stress levels were found among parents who had children other than their baby in the NICU, parents whose baby had a young gestation age and a low birthweight, parents whose baby was on a respiration device, and parents who had experienced a stressful event in the past year. The stress levels of parents whose premature baby was hospitalized in the NICU were also high. The family-centred approach is recommended to identify and meet all the needs of all such parents.
