Genitourinary Dysfunction Prevalence in Parkinson Disease Patients
Authors: Irene Rasanu
Published: July 2019

The goal of this study was to estimate the prevalence of patient-reported genitourinary dysfunction symptoms in Parkinson’s disease patients from the Southeastern Romania.

The study was performed on 86 patients with idiopathic Parkinson’s disease from 5 Outpatients Clinics of Constanta, 56% males, mean age 70.6 years, mean disease duration 6.33 years. The patients have been assessed for the presence of genitourinary symptoms using the Scale for Outcomes in Parkinson’s Disease for Autonomic Symptoms (SCOPA-AUT) as a self-administered questionnaire.

The vast majority of study population (98.8%) reported at least one genitourinary dysfunction. The most common urinary symptom was nocturia (95.3%, 95% CI 90.8-99.7), followed by pollakiuria (82.5%, 95% CI 74.4-90.5), difficulty passing urine and urge to urinate (each present in 76.7% of studied PD patients, 95% CI 67.4-85.3), incomplete bladder emptying (75.5%, 95% CI 66.4-84.5), urinary incontinence (67.4%, 95% CI 57.5-77.3). As frequency, most of the study subjects experienced genitourinary symptoms only “sometimes”. None of the investigated PD patients affected by genitourinary symptoms used specific medication therapy.

Published: July 2019

Introduction. Numerous clinical symptoms found in patients with temporomandibular disorders include non-carious lesions, such as V-shaped lesions, wear facets, enamel cracks, and impressions on the tongue or changes in the buccal mucosa. In addition, loosening and dislocation of teeth may occur.

Aim. The aim of the study was to obtain a clinical assessment of the prevalence and severity of non-carious lesions of dental hard tissues (attrition and abrasion) in patients treated for functional temporomandibular disorders.

Material and methods. The clinical research was performed among 45 patients of both genders, aged 16-38 years, treated at the Department of Functional Masticatory Disorders at the Medical University of Lublin, Poland. The study group consisted of 30 patients with diagnosed temporomandibular disorders. The control group included 15 individuals with no diagnosed temporomandibular disorders. The control group was selected using the method of analogues (considering age, gender and dental status). The examinations were performed before the treatment and twelve weeks after its beginning.

Results. The study found significantly higher values of the prevalence and severity of attrition in the patients group, in comparison with the control group (p < 0.05). In the case of abrasion, higher values of the studied variables of prevalence and severity of lesions in the patients, compared to controls, were also found, but the differences were not statistically significant (p > 0.05).

Conclusions. Attrition occurs more frequently and is more severe in patients with diagnosed temporomandibular disorders than in those without such diagnosis. However, no significant differences have been found in the prevalence and severity of abrasion in both groups.
An underestimated technique. Does pressurized and pressure-assisted capillary electrochromatography have potential in drug and pharmacological-active compounds analysis?
Authors: Trzebiatowski Michal Zmuda , Gwarda Radoslaw L. , Dzido Tadeusz H.
Published: July 2019

Pharmaceutical analysis guarantees patient safety all over the world. Thus, continuous development of existing analytical techniques is still very important. Pressurized capillary electrochromatography and pressure-assisted capillary electrochromatography are hybrid separation techniques that combine the selectivity of liquid chromatography and the high separation efficiency of capillary electrophoresis. They use a smaller amount of reagents and samples, hence, reducing the total cost of analysis. Therefore they have found application in a number of pharmaceutical and biomedical analysis. This review article focuses on the use and importance of pressurized and pressure-assisted capillary electrochromatography in pharmaceutical and biomedical analysis, taking into account types of detectors and capillaries used. Despite the fact that pressurized capillary electrochromatography and pressure assisted capillary electrochromatography offer many possibilities and have been available for over a dozen years, they are still underdevelopment and not fully explored.

Authors: Elaigwu Audu Michael
Published: July 2019

The study assesses the proximate composition, amino acid profile and its content and chemical indices of the sun-dried Schilbe mystus, Bagrus bayad, Oreochromis niloticus, Clarias anguillaris and Petrocephalus bane bane from Tiga Dam Reservoir, Nigeria. The proximate composition varied significantly (p<0.05) in all five species of fish and these ranged as follows: Moisture (4.79 - 9.52 g/100 g), Crude Protein (42.20 - 57.71 g/100 g), Ash Content (0.90 - 12.51 g/100 g), Ether Extract (3.41 - 9.93 g/100 g), Crude Fibre (0.62 - 5.08 g/100 g), Nitrogen Free Extract (12.28 - 42.70 g/100 g) and Dry Matter (90.48 - 95.21 g/100 g). The amino acid also differed significantly (p<0.05). The nine essential amino acids found in the five species of fish were Lysine (4.21 - 6.34 g/100 g), Histidine (1.96 - 4.30 g/100 g), Arginine (5.80 - 8.21 g/100 g), Threonine (1.93 - 5.05 g/100 g), Valine (2.91 - 5.53 g/100 g), Methionine (1.74 - 3.80 g/100 g), Isoleucine (2.04 - 3.37 g/100 g), Leucine (3.64 - 7.18 g/100 g) and Phynylalanine (1.90 - 4.23 g/100 g). Whereas, the eight non-essential amino acids included: Serine (2.12 - 5.22 g/100 g), Glutamic acid (13.24 - 16.30 g/100 g), Proline (3.12 - 6.29 g/100 g), Glycine (4.20 - 9.08 g/100 g), Alanine (5.00 - 6.36 g/100 g), Cysteine (0.94 - 1.24 g/100 g), Tyrosine (2.33 - 3.33 g/100 g) and Aspartic acid (6.34 - 11.01 g/100 g). P. bane bane was first in terms of crude protein; S. mystus had the highest lipid and essential amino acid content. Also, C. anguillaris recorded the highest calorific value and best amino acid content. Thus, P. bane bane can serve as a source of animal protein to balance deficiencies in humans. Both S. mystus and C. anguillaris can be used as a nutrient base for high energy food and oil in the food industry.
Factors Influencing Walking Distance to the Preferred Public Transport Stop in selected urban centres of Czechia
Authors: Ivan Igor , Horák Jiří , Zajíčková Lenka , Burian Jaroslav , Fojtík David
Published: July 2019

One of the ways of improving the attractiveness of public transport is to bring it closer to its potential users. A long walking distance from a stop is often one of the critical factors limiting its more frequent and extensive use. Studies dealing with the accessibility of transport networks usually work only with the closest stop. This article analyses the actual walking distance from the place of residence to the preferred stop. The survey used a questionnaire method and was conducted in two cities in the Czech Republic—Ostrava and Olomouc. Based on the results of the study, the average walking distance was assessed and the impact of demographic characteristics (gender, age, education, number of members in the household, economic activity, the presence of a child in the household, and car ownership), transport behavior (preferred mode of transportation, car convenience and opinions on public transport), and urban characteristics (prevailing housing type) on the walking distance were analyzed. The main findings prove a significant impact on walking distance by a number of these factors, but the preferred use of a car for commuting or unemployment does not significantly affect walking distance.
The lawn grew too quickly! Perception of rural idyll by Czech amenity migrants
Authors: Píša Jan
Published: July 2019

The arrival of amenity migrants has significant impacts for many rural areas in economic, environmental and social terms. While the causes of relocation from cities to remote rural localities can be generally understood as attempts to change the way of life, the consequences of this phenomenon are relatively diverse. Perception of rural space from the migrant´s point of view stems partly from the so-called rural idyll, which shapes the image of the countryside across society, especially through media, tourism and recreation. This study aims to discover links between rural idyll and motivational factors of the Czech amenity migrants. Semi-structured interviews with the Czech amenity migrants have been used in order to uncover the social dimension of the phenomenon of rural idyll. Emphasis has been put both on the genesis of their relationship to the rural environment, but also on the consistency and differences between expectations and the reality of rural life. I identify the key role of tourism and recreation in shaping the initial perception of rural space, whereas the role of media is rather implicit. In the perception of amenity migrants, the initial image of rural space differed only slightly when the physical environment of rural space is considered but a mismatch is found between initial ideas about rural communities and their real experience after moving there.
Improving the quality of life in cities using community gardens: from benefits for members to benefits for all local residents
Authors: Dubová Lenka , Macháč Jan
Published: July 2019

Recent effects of globalization, urbanization and climate change have resulted in an increasing interest in the quality of life in cities and seeking pathways for its improvement. At the same time, there are changes in society and lifestyles that may challenge or facilitate these pathways. Community gardens (CGs) represent an effort to provide more sustainable urban economies, while reflecting on the public demand for cultivation of own crops. However, members of CGs may not perceive all the benefits that CGs provide for their surroundings. Using two case studied from Czechia (CG Kuchyňka and CG Vidimova in Prague) the aim of this paper is a comparison of the benefits perceived by community garden members and the evaluated net social benefits of community gardens in cities for all local residents. Through a questionnaire survey, the paper answers the research question of the benefits of community gardens perceived by community garden members. An economic assessment based on cost-benefit analysis was made to answer the question of the value of the net social benefits of community gardens in cities. Our comparison shows that the net social benefits are higher than perceived by their members. Net present benefits of EUR 31 550 for CG Kuchyňka and EUR 1 175 for CG Vidimova were quantified in a 50-year horizon. This economic analysis should contribute to greater support for community gardens by city governments and spatial planners.
Empirical verification of the relationship between creative life orientations of the creative class and the creative city
Authors: Sokół Aneta
Published: July 2019

In the last few years there has been a fundamental change in the approach to the issue of creativity in economics, and it is increasingly referred that the era of the economics of creativity has started. Currently, it is claimed that no matter how much knowledge one possesses, it is important how it is creatively processed and how it will be used. Both theoreticians and practitioners agree on its role as a source of competitive advantage in the micro and macroeconomic sphere. The aim of the article is to consider cognitive, theoretical and methodological as well as empirical issues (questionnaire research) on the development of creative life orientations of the creative class in creative cities. The research results allow us to present a recommendation for managers managing creative cities. They are for example: tolerance for new and unknown things; cooperation that are made by outstanding individuals and social support, acceptance of creativity and creators.
Public Ethnocentrism. An Obstacle of Worldwide Economic Development: Concept and a Preliminary Research
Authors: Dobrowolski Zbysław , Szejner Tomasz
Published: July 2019

Objective: The phenomenon of ethnocentrism in the public sector has not been well recognized. The study was aimed at initiating an effort to fill the research gap by introducing the concept of “public ethnocentrism” and presenting empirical evidence from a preliminary test of the concept.

Methodology: while analysing and seeking full contextual understanding of the public ethnocentrism the ethnographic public representative’s observation and open-ended interviews have been chosen. Study of public ethnocentrism in Poland have been supplemented by interviews with 11 representatives of public sector from the USA, Germany, Czech Republic, Austria, Indonesia, Malaysia, Tanzania, Namibia and Mexico.

Findings: Studies have shown a scale of willingness to use an ethnocentric attitude when making decisions in a public organization. It was found that public ethnocentrism restricts innovation by disrupting public choice.

Value Added: Two new research questions are identified.

Recommendations: There is a need to create an Ethnocentrism Perception Index (EPI). The tendency for ethnocentric behaviour should be taken into accounts when determining whether formal and informal institutions are conducive to running a business in a given country.
The energy union - Perspectives for consolidating the European Union through a common energy market
Authors: Şanta Ana-Maria Iulia
Published: July 2019

The European Union develops a new energy policy as an answer to the challenges of climate change which is a global issue affecting all of us. The package “Clean Energy for All Europeans” adopted by the European Commission in 2016, contains instruments for a new energy policy at the level of the European Union, based on an Energy Union, on promoting energy efficiency and the use of Clean Energy. These are the first steps in creating an institutional and legal framework for a common energy market of the European Union. This way the Internal Market of the European Union would be completed by a common energy market and the result would be a consolidated European Union. This is the research hypothesis the present paper is dealing with. It analyzes as well the impact of the new energy policies on the business environment in terms of new innovative business models at European Union level. The research is based on an interdisciplinary approach considering aspects of European policy, European law, business and economics. Qualitative research methods, such as the analysis of European regulations and provisions representing the basis for a harmonized framework in the energy sector at European Union level and case studies from European Union Member States will be applied. Relevant indicators provided by the European Commission and by Eurostat statistics analyzed in the present paper will complete this assessment.

Authors: Cojocaru Ioana , Luculescu Livia , Negoescu Daniela , Strâmbu Irina
Published: July 2019

Clostridium difficile is an anaerobic bacterium than can colonise the lower intestine and cause enterocolitis in susceptible patients. Clostridium difficile infection (CDI) is typically a nosocomial infection, favoured by treatment with antibiotics (especially with broad-spectrum drugs), proton pump inhibitors, but also comorbidities, old age and prolonged hospitalisation. Based on the observation that in the past years, the frequency of nosocomial CDI has increased in the Institute of Pulmonology, Bucharest, this retrospective observational study aimed to analyse the characteristics of admitted patients who develop CDI, in order to identify possible particular features and risk factors. Accordingly, medical files from 80 patients admitted from January 2015 to August 2017 were analysed for demographic data, respiratory diagnosis, comorbidities, blood tests, treatments prescribed, time of CDI onset, evolution and outcome. The number of patients studied was 29 in 2015, 16 in 2016 and 35 in 2017, with slight male predominance. Totally, 54 patients (67.5%) had tuberculosis (pulmonary or pleural), 12 had lung cancer, five had respiratory infections, two had chronic obstructive pulmonary disease and seven had other diseases. All patients but nine were receiving antibiotics: tuberculosis drugs, cephalosporins, fluoroquinolones and beta-lactams. About half of the patients received proton pump inhibitors. Most patients had several comorbidities. Mean time since admittance to onset of diarrhoea was 20 days. CDI was treated with metronidazole or vancomycin. The evolution was favourable in 90% of patients, but eight patients (10%) died

This study highlights a high frequency of CDI in patients treated for tuberculosis. Due to insufficient data, no epidemiological consideration could be made. Further studies are needed to assess the relationship among tuberculosis, tuberculosis treatment and CDI.
Comparison of three risk scores to predict outcomes in upper gastrointestinal bleeding; modifying Glasgow-Blatchford with albumin

Published: July 2019

Introduction. Management of upper gastrointestinal bleeding (UGIB) is of great importance. In this way, we aimed to evaluate the performance of three well known scoring systems of AIMS65, Glasgow-Blatchford Score (GBS) and Full Rockall Score (FRS) in predicting adverse outcomes in patients with UGIB as well as their ability in identifying low risk patients for outpatient management. We also aimed to assess whether changing albumin cutoff in AIMS65 and addition of albumin to GBS add predictive value to these scores.

Methods. This was a retrospective study on adult patients who were admitted to Razi hospital (Rasht, Iran) with diagnosis of upper gastrointestinal bleeding between March 21, 2013 and March 21, 2017. Patients who didn’t undergo endoscopy or had incomplete medical data were excluded. Initially, we calculated three score systems of AIMS65, GBS and FRS for each patient by using initial Vital signs and lab data. Secondary, we modified AIMS65 and GBS by changing albumin threshold from <3.5 to <3.0 in AIMS65 and addition of albumin to GBS, respectively. Primary outcomes were defined as in hospital mortality, 30-day rebleeding, need for blood transfusion and endoscopic therapy. Secondary outcome was defined as composition of primary outcomes excluding need for blood transfusion. We used AUROC to assess predictive accuracy of risk scores in primary and secondary outcomes. For albumin-GBS model, the AUROC was only calculated for predicting mortality and secondary outcome. The negative predictive value for AIMS65, GBS and modified AIMS65 was then calculated.

Result. Of 563 patients, 3% died in hospital, 69.4% needed blood transfusion, 13.1% needed endoscopic therapy and 3% had 30-day rebleeding. The leading cause of UGIB was erosive disease. In predicting composite of adverse outcomes all scores had statistically significant accuracy with highest AUROC for albumin-GBS. However, in predicting in hospital mortality, only albumin-GBS, modified AIMS65 and AIMS65 had acceptable accuracy. Interestingly, albumin, alone, had higher predictive accuracy than other original risk scores. None of the four scores could predict 30-day rebleeding accurately; on the contrary, their accuracy in predicting need for blood transfusion was high enough. The negative predictive value for GBS was 96.6% in score of ≤2 and 85.7% and 90.2% in score of zero in AIMS65 and modified AIMS65, respectively.

Conclusion. Neither of risk scores was highly accurate as a prognostic factor in our population; however, modified AIMS65 and albumin-GBS may be optimal choice in evaluating risk of mortality and general assessment. In identifying patient for safe discharge, GBS ≤ 2 seemed to be advisable choice.
Comparative Study of Self-Compacting Concrete Containing Lightweight and Normal Aggregates
Authors: Pannem Ramamohanrao , Kumar Padmaja P.
Published: July 2019

Based on the available literature, a simple method was adopted to calculate the packing density of aggregates and thereby reduce their void content by optimising their packing aggregates and by using two different sizes of coarse aggregates and fine aggregates. This study provides an understanding of the way in which the shape of aggregates affects the properties of self-compacting concrete (SCC). The fresh, hardened, and durable properties of SCC with normal and lightweight fly ash coarse aggregates are found at the corresponding age of the curing. Their values were compared with respect to SCC containing normal aggregates. A mix with fly ash aggregates was found to have better fresh concrete properties due to the round shape of the aggregates. After the packing of the aggregates, this mix was found to have better mechanical and durability properties than all the other concrete mixes.
The Use of Polyethylene Terephthalate Waste for Modifying Asphalt Concrete Using the Marshall Test
Authors: Ogundipe Olumide Moses
Published: July 2019

This study considers the use of polyethylene terephthalate (PET) waste for modifying asphalt concrete. In the study, the optimum bitumen content of asphalt concrete was replaced with 4%, 6%, 8%, 10%, 12%, 14% and 16% of PET waste; the Marshall test was conducted on the samples. A comparison of the unmodified and PET-modified asphalt concrete showed that the stability of the modified asphalt concrete was reduced. The maximum stability for the PET waste-modified asphalt concrete was recorded at a content of 12% PET waste. This gives about a 20.4% reduction in stability. The study reveals that the addition of PET waste to the asphalt concrete causes a reduction in the flow value except with the addition of 14% and 16 % waste. This implies that the introduction of PET waste could improve the permanent deformation resistance of asphalt, although there is concern about a reduction in fatigue resistance.
Alternative Micro-Milled Binders in Cold Recycling Technologies
Authors: Šedina Jakub , Valentin Jan , Mondschein Petr , Suda Jan
Published: July 2019

In addition to bituminous binders (bituminous emulsion, foamed bitumen), hydraulic binders are applied in cold recycling technologies to increase the strength of a final structural layer as well as to increase its resistance to water and frost impacts. This paper deals with the use of energy by-products from fluidized bed coal combustion and mineral waste and their modification into reactive material with the potential of replacing commonly used hydraulic binders. The increase in the reactive potential takes place through a high-speed milling process where the mechanical-chemical activation of the material takes place. This process is associated with the refinement of the material, a higher proportion of micro and nanoparticles, an increased surface area, opening of particles, etc. The material treated exhibits binding properties, and it can be used as an active filler that allows for the partial or complete substitution of hydraulic binders. The experimental part is focused on the application of alternative binders to cold recycling mixtures and their assessment according to valid technical regulations, i.e., an assessment of their indirect tensile strength and water susceptibility as well as compressive strength and resistance to the effects of water and frost.
The Use of Effective Coagulants and Flocculants to Intensify the Process of Water Purification at Coke Plants
Authors: Galkina Olena , Blahodarna Halyna
Published: July 2019

The paper proposes a reagent method of water purification at the Kharkiv Coke Plant when using the phenolic wastewater in the water-circulating system, which corresponds to industry standards, together with coagulant (aluminum sulfate, aluminum hydroxychloride Pro-AQUA-18) and flocculant treatment (Extraflock and Besfloc). The use of cationic flocculants in water treatment has shown a high degree of efficiency in the removal of suspended substances compared with the Pro-AQUA-18 coagulant at a dose of 50 mg/dm3 or flocculant – 2-4 mg/dm3; it does not lead to the secondary pollution of the water and does not increase its corrosive activity. The purification of the clarified water was carried out using a filtration unit with a filtering load from a layer of quartz sand. The use of the proposed reagent method of water purification will allow it to be used for the technical purposes of the enterprise, reduce the consumption of fresh water, and eliminate the discharge of phenolic wastewater into the municipal sewer network.
Study of the Mechanical Behaviour of a Clayey Soil Under Normal and Frozen Conditions
Authors: Kumar Amit , Soni Dharmender Kumar
Published: July 2019

Lime and cement are quite compatible for stabilizing clayey soils; changes in a thermal regime may inversely affect the advantages of stabilized soil. The present study interprets changes in the mechanical behaviour of frozen and unfrozen Himalayan soil samples through an unconfined compressive strength test. The soil was treated with ground eggshell powder (3%-9%) and alkali activator (Sodium chloride) (2%-6%); it was reinforced with arbitrarily distributed polypropylene fibers (0.05%-0.15%). Standard 7, 14 and 21-day-old soil specimens were tested in unfrozen conditions, while fresh 21-day-old soil specimens were tested after 3, 5 and 10 freeze-thaw cycles. The design of the experiments was based on the Taguchi technique and arranged in an orthogonal array. The results of the research clearly show that poultry waste (eggshell powder) and alkaline soil stabilizer improved the strength behaviour of the subject soil. On the other hand, the polypropylene fibers played an important role in changing the brittle behaviour of the stabilized soil to ductile behaviour. The sudden collapse of a structure may be avoided by using polypropylene fibers.

Published: July 2019

At present, high traffic intensity level on the roads currently saturates a great demand for individual transportation. Mobility is an important part of everyday activities in cities. The increasing number of passenger and freight vehicles on the widening transport infrastructure raises several problems. The range of use of public passenger transport does satisfy enough the citizens needs and its use is constantly decreasing, especially in the new EU countries. One of the reasons is also the growing sale and production of new passenger cars in the EU, resulting in congestion in the road infrastructure of cities and environmental problems. These issues are dealt with the modern City Logistics concept. The contribution focused on the basic principles of city logistics, the reasons for its development and, in particular, the possibilities of practical use. An example is the city of Trenčín in Slovakia, where a regional rail passenger transport is proposed for city traffic service including Park and Ride system.

Published: July 2019

Seaweed has potential nutrient content such as carotenoids, vitamins, fatty acids, carbohydrates, minerals, and other essential substances. Carotenoids have important biological functions as an antioxidant, and immunostimulatory which can prevent the disease, anti-inflammatory, anti-stress, anti-aging, and protect the skin from the harmful effects of ultraviolet radiation. Seaweed generally consumed as a vegetable by people in Bali, known as the local name Bulung Boni (Caulerpa spp.) and Bulung Sangu (Gracilaria spp.).. So far there has been no report or results of research on the effects of extract ethanol of Bulung Boni (Caulerpa sp.) and Bulung Sangu (Gracilaria sp.) as an antioxidant that can prevent lipid peroxidation which can be seen in decreased level of MDA in liver tissue or blood plasma. Therefore it is necessary to determine of plasmaMDA level of Wistar rat after fed high cholesterol diet treated with extract ethanol of Caulerpa sp. and Gracillaria sp. This experimental study used completely randomized design. Research using total of 24 Wistar rats divided into six sample groups of equal size, all fed with a diet high in cholesterol especially in negative control. The study consisted of negative control group (standard diet), positive control group (high cholesterol diet), high-cholesterol diet with Caulerpa sp. extract dose of 20 mg and 60 mg/100 g, high cholesterol diet with Gracilaria sp. extract dose of 20 mg and 60 mg/100 g body weight rat per day.The study resulted that rats fed high cholesterol diet with treated extract ethanol Caulerpa sp. and Gracilaria sp. with a dose of 20 mg and 60 mg per 100 g body weight rat / day had plasma MDA level significantly lower (p <0.05) compared with rats fed high cholesterol diet without treated with extract of Caulerpa sp. and Gracilaria sp.

Published: July 2019

One of the modern plant breedings through genetic engineering is Agrobacterium tumefaciens-mediated transformation. Agrobacterium tumefaciens-mediated transformation can be performed in vitro or in planta. In planta transformation arises from the weaknesses of the in vitro method such as need high hygiene standard, professional tissue culture experts, and more time to prepare explants and somaclonal variation. In planta transformation is a method to transfer the gene to the plant genome without any tissue culture stages. The aims of this research were to know the possibility of the prick and soak in planta method with the target of tomato seeds and to know the most suitable inoculation time for tomato seeds transformation by prick and soak method the transformation is done by pricking the seeds and soaking them in the A. tumefaciens suspension. The treatments in this study were 1 and 2 days inoculation time to test the efficacy of prick and soak in planta transformation method. Tomato seeds were pricked with a needle on the center once, and then soaked in A. tumefaciens strain LB4404 suspension carrying pKYS-SoSPS1 plasmid with Neomycin Phosphotransferase (NPTII) and Saccharum officinarum Sucrose Phosphate synthase (SoSPS1) genes. Visualization of tomato’s DNA samples after PCR showed that 1-day inoculation sample was positively integrated with NPTII gene and negative in the 2 days inoculation treatment.

Published: July 2019

One of grape cultivars widely used as raw material for wine production is ‘Shiraz’ cultivar. Propagation of this cultivar is necessary for the provision of grape as a wine making material in Bali. In vitro culture is an alternative propagation technique than can be employed to produce planting materials in a shorter time. This research aims to determine the most suitable medium and growth regulator combination in inducing grape cv. ‘Shiraz’ callus in vitro. The study was conducted from November 2017 until February 2018 at Plant Tissue Culture Laboratory, Biology Study Program, Udayana University. The explants used were young stem of grape cv. ‘Shiraz’ and the experiment was conducted using factorial design with two factors. The first factor was basal medium used (MS and WPM) and the second factor was IBA concentration (0; 0.5 and 1 mgL-1) and BAP (0, 1 and 2 mgL-1). The results showed that the highest percentage of callus induction (60%) was obtained on WPM medium without growth regulator combination (control). However, the fastest time of callus appear was on MS medium + 2 mgL-1 BAP without IBA, which was 17 days after planting. The texture and color of callus resulted on this research were friable with white, greenish white, greenish yellow and green in color.

At this moment composite resin is the most widely used material for dental restoration. The content of the resin is a mixture of monomer bisphenol A glycidyl methacrylate (Bis-GMA), trimethylene glycol dimethylmethacrylate (TEGDMA) and urethane dimethacrylate (UDMA) and special particle fillers made of radioopaque glass. Many studies have been conducted to study the biocompatibility of composite resin, especially the cytotoxicity and genotoxicity test. Genotoxicity tests that are often carried out are comet test for DNA damage protection and micronuclei test for protection of genome damage. The monomer content of composite resins can have a genotoxic effect.

Published: July 2019

Material komposit dengan laminasi serat penguat karbon dan basalt telah diproduksi melalui proses cetakan injeksi. Tujuan penelitian adalah menganalisa laju korosi material komposit oleh air laut. Perendaman komposit hibrida untuk masing-masing variasi dilakukan pada air laut dengan durasi waktu perendaman selama 2 minggu, 4 minggu, dan 6 minggu. Hasil uji menunjukkan seluruh variasi komposit hibrida mengalami penyerapan dibuktikan dengan meningkatnya massa benda uji dari setiap durasi waktu perendaman. Peningkatan massa untuk masing-masing komposit hibrida sangat besar terjadi pada minggu ke-2 (dua) yaitu 3,9%  untuk CFRP, 1,4% untuk B2C3B2C3, 1,3% untuk B4C6, 1,3% untuk C2B2C2B2C2, dan 1,5% untuk BFRP. Kemudian untuk durasi perendaman selanjutnya relatif tetap (constant). Dari hasil tersebut disimpulkan bahwa perendaman komposit hibrida dengan serat basalt/carbon/epoxy sangat rendah dari minggu ke minggu. Analisa SEM menunjukkan pada setiap komposit hibrida teramati terjadi korosi disebabkan karena serat basalt memiliki kandungan besi (Fe), tetapi laju korosi sangat rendah (< 0,5%). Efek korosi ditunjukkan dengan adanya zona delaminasi yang dapat menurunkan kekuatan dan keuletan dari komposit hibrida.

Composite materials with carbon fiber and basalt fiber laminates have been produced through the injection molding process. The aim is to analyze the corrosion rate of composite materials by sea water. Immersion of hybrid composites for each variation was carried out on sea water with a duration of immersion time of 2 weeks, 4 weeks and 6 weeks. The test results showed that all variations of hybrid composites experienced absorption as evidenced by the increase in the mass of the specimen from each duration of immersion time. The mass increase for each hybrid composite was very large at the second week is 3.9% for CFRP, 1.4% for B2C3B2C3, 1.3% for B4C6, 1.3% for C2B2C2B2C2, and 1,5% for BFRP. Then for the duration of subsequent immersion it is relatively constant. From these results it was concluded that immersion of hybrid composites with basalt / carbon / epoxy fibers was very low from week to week. SEM analysis showed that each hybrid composite observed corrosion due to basalt fibers having iron (Fe) content, but the corrosion rate was very low (<0.5%). Corrosion effects are indicated by a delamination zone which can reduce the strength and ductile of hybrid composites.

Diante do contexto econômico, baseado em incertezas e rodeado pela concorrência, no que tange a globalização, percebem-se vários efeitos na visibilidade de novas oportunidades e ameaças. Diante disso, existe a necessidade de manter o foco no cliente e sua fidelização como alternativa de permanência no mercado. O objetivo geral foi propor ações de pós-venda para retenção e fidelização de clientes. Justifica-se a abordagem deste tema, com o intuito de mostrar para as empresas que a venda não termina após o pagamento e a entrega do bem adquirido, mas que há muito trabalho a ser feito após isto, fator que leva as empresas a preocuparem-se mais com o cliente, e leva os clientes a valorizar mais as empresas que demonstram esta preocupação. A problemática que buscou-se solucionar: Quais as estratégias de pós-venda mais adequadas para a obtenção da vantagem competitiva? O referencial aborda conceitos de marketing, marketing de relacionamento, satisfação e fidelização do cliente, ações de pós-venda e vantagem competitiva. Quanto a metodologia elaborou-se um estudo de caso, com o intuito de conhecer a realidade da empresa no que tange as ações de pós-venda, por meio de uma entrevista com o gestor, bem como, elaborou-se uma pesquisa com os clientes da organização. Como principais resultados, a pesquisa apontou que os clientes possuem um alto grau de exigência no que tange ao assunto abordado, em contrapartida a empresa objeto de estudo não possui um sistema estruturado e voltado ao pós-venda.

Laguerre wavelet method for solving Troesch equation
Authors: GÜMGÜM Sevin
Published: July 2019

The purpose of this paper is to illustrate the use of the Laguerre wavelet method in the solution of Troesch’s equation, which is a stiff nonlinear equation. The unknown function is approximated by Laguerre wavelets and the equation is transformed into a system of algebraic equations. One of the advantages of the method is that it does not require the linearization of the nonlinear term. The problem is solved for different values of Troesch’s parameter (μ) and the results are compared with both the analytical and other numerical results to validate the accuracy of the method.

Perguruan tinggi swasta di Palembang dalam membangun SIE/sistem informasi eksekutif Nya secara sendiri-sendiri dan belum ada pedoman yang digunakan sebagai acuan, walaupun diketahui proses bisnis sistem informasi akademik di Perguruan Tinggi secara umum adalah sama. Berdasarkan pengamatan belum ada kerangka kerja SIE akademik yang tersedia dan bisa dijadikan sebagai pedoman untuk membangun SIE akademik. Tujuan penelitian ini adalah merancang kerangka kerja SIE akademik dengan memperhatikan berbagai faktor dan permasalahan yang ditemukan, seperti dari kerangka kerja SIE akademik, sistem bagaimana yang akan dibuat dan tatacara pembuatannya. Faktor lain, kerangka SIE akademik  yang akan dibuat harus bersifat dinamis yang bisa dimungkinkan untuk dilakukan perubahan sesuai dengan kondisi dan kebutuhan perguruan tinggi. Penelitian ini menggunakan metode EAP (Enterprise Architecture Planning) untuk menganalisis dan membuat kerangka kerja SIE akademik. Hasil dari penelitian ini adalah kerangka kerja sistem dalam bentuk arsitektur data dan  arsitektur aplikasi. Kerangka kerja SIE akademik ini diharapkan dapat digunakan sebagai pedoman dalam perencanaan dan pengembangan SIE akademik  di perguruan tinggi swasta di Palembang.

Abstract

Private universities in Palembang are building their own EIS / executive information systems and a guide is not used as a reference, although it is known that the business process of academic information systems in universities is generally the same. Based on the observations, there is no scientific EIS framework and it can be used as a guide to build the academic EIS. The purpose of this research is to design the scientific structure of the EIS, taking into account the various factors and problems encountered. Another factor, the scientific structure of the EIS that will be created, must be dynamic, which can be modified according to the conditions and needs of the university. This study uses the EAP (Enterprise Architecture Planning) methodology to analyze and build an academic EIS framework. The results of this study are system structures in the form of data architecture and application architecture. The scientific framework of the EIS serves as a guide for the planning and development of the academic EIS in the private universities of Palembang.

La construcción del entramado narrador -protagonista textual- autor en la obra del escritor santafesino Alcides Greca (1889-1956)
Authors: Antequera María Florencia
Published: July 2019

En este artículo nos interesa abordar cómo opera la articulación narradorprotagonista textual- autor, en los relatos de viajes del intelectual argentino Alcides Greca (San Javier 1889- Rosario, 1956). De alguna manera, esta cuestión nos conduce a plantearnos algunas aristas del funcionamiento de lo autobiográfico en su literatura. Teniendo en cuenta esos resortes del género relato de viajes, que ocupan un lugar de relevancia, como la descripción, la intertextualidad, la mirada performativa, por citar solo algunos, entendemos que el entramado narrador- protagonista textual- autor pivotea esta y otra serie de rasgos vinculados y que resulta, a las claras, necesario cartografiar: el pacto autobiográfico, el contrato de lectura, el despliegue del yo en el texto, el efecto de realidad. El estatuto ficcional del género (y de estos relatos de viajes particularmente) es peculiar: abonamos la tesitura de que tanto los recuerdos como los medios de locomoción vehiculizan la construcción de la cuestión autobiográfica.
Kritik Sastra Ekologis terhadap Novel-novel Terbaru Indonesia
Authors: Andriyani Noni , Piliang Wilda Srihastuty Handayani
Published: July 2019

Environmental literary works appear as a form of literary sensitivity to society and the environment which has specific environmental tendencies. Studies using the theory of ecological literature began in around 2008 and above with a very limited number. Therefore, the development of studies of literary works with this theory is very necessary. The creation of public opinion about the importance of protecting the environment to reduce the impact of global warming is very necessary. Later, through several novels, authors have done it. However, not all messages in the novel are clearly conveyed so that they still need ecological literary criticism to understand them. Based on this, the problem raised in this study is "What is the ecological literary criticism of Indonesia's latest novels?". Data collection and data analysis is done by descriptive and content analysis methods. Data are classified and analyzed with ecological literary concepts according to Garrard including (1) pollution; (2) wilderness; (3) disaster; (4) housing / residence; (5) animals; and (6) earth. The research findings and discussion show that Indonesia's latest novels are friendly with their environment, want to describe as much detail as possible about the universe, worship nature, and are always interested in natural changes. Ecological literary concepts are contained in Indonesia's latest novels to describe the natural situation as well as to criticize human treatment of nature. Indonesia's latest novels teach that an attitude of compassion for nature gives rise to desire and behavior to protect and preserve nature as well as possible.
Coverage and Stability of NHx Terminated Cobalt and Ruthenium Surfaces: a First Principles Investigation
Authors: Liu Ji , Nolan Michael
Published: July 2019

In the atomic layer deposition (ALD) of Cobalt (Co) and Ruthenium (Ru) metal using nitrogen plasma, the structure and composition of the post N-plasma NHx terminated (x = 1 or 2) metal surfaces are not well known but are important in the subsequent metal containing pulse. In this paper, we use the low-index (001) and (100) surfaces of Co and Ru as models of the metal polycrystalline thin films. The (001) surface with a hexagonal surface structure is the most stable surface and the (100) surface with a zigzag structure is the least stable surface but has high reactivity. We investigate the stability of NH and NH2 terminations on these surfaces to determine the saturation coverage of NHx on Co and Ru. NH is most stable in the hollow hcp site on (001) surface and the bridge site on the (100) surface, while NH2 prefers the bridge site on both (001) and (100) surfaces. The differential energy is calculated to find the saturation coverage of NH and NH2. We also present results on mixed NH/NH2-terminations. The results are analyzed by thermodynamics using Gibbs free energies (ΔG) to reveal temperature effects on the stability of NH and NH2 terminations. Ultra-high vacuum (UHV) and standard ALDoperating conditions are considered. Under typical ALD operating conditions we find that the most stable NHx terminated metal surfaces are 1 ML NH on Ru (001) surface (350K-550K), 5/9 ML NH on Co (001) surface (400K-650K) and a mixture of NH and NH2 on both Ru (100) and Co (100) surfaces.
