A Semantics and Complete Algorithm for Subsumption in the CLASSIC Description Logic
Authors: Borgida A. , Patel-Schneider P. F.
Published: July 2018

This paper analyzes the correctness of the subsumption algorithm used in CLASSIC, a description logic-based knowledge representation system that is being used in practical applications. In order to deal efficiently with individuals in CLASSIC descriptions, the developers have had to use an algorithm that is incomplete with respect to the standard, model-theoretic semantics for description logics. We provide a variant semantics for descriptions with respect to which the current implementation is complete, and which can be independently motivated. The soundness and completeness of the polynomial-time subsumption algorithm is established using description graphs, which are an abstracted version of the implementation structures used in CLASSIC, and are of independent interest.
Pac-Learning Recursive Logic Programs: Efficient Algorithms
Authors: Cohen W. W.
Published: July 2018

We present algorithms that learn certain classes of function-free recursive logic programs in polynomial time from equivalence queries. In particular, we show that a single k-ary recursive constant-depth determinate clause is learnable. Two-clause programs consisting of one learnable recursive clause and one constant-depth determinate non-recursive clause are also learnable, if an additional ``basecase'' oracle is assumed. These results immediately imply the pac-learnability of these classes. Although these classes of learnable recursive programs are very constrained, it is shown in a companion paper that they are maximally general, in that generalizing either class in any natural way leads to a computationally difficult learning problem. Thus, taken together with its companion paper, this paper establishes a boundary of efficient learnability for recursive logic programs.
A pessoa humana como categoria fundamental da educação sexual: uma perspectiva fenomenológica
Authors: Gomes Vânia
Published: July 2018

In this article we discuss the ontological foundations of the human person for sexual and gender education. The extremes of materialism, mechanicism, idealism and essentialism tends to annul bodiliness when approaching these foundations, thus we explore the necessity of an anthropological foundation of body-centered sexuality. Methodologically, we made a choice for the phenomenology of bodiliness in Merleau-Ponty and analyzed the concrete aspects of bodiliness and sociableness, discussing its overture to transcendence and its challenges of the necessary utopias to the exercise of human freedom. We conclude that bodiliness is not a sufficient condition, but it is a necessary condition for the integral study of human sexuality, which allows us to situate sociableness and develop transcendence. This prevents a study of sexuality without body, as it occurs in the essentialist and mechanistic approaches.
Manifestaciones de violencias entre alumnos de educación superior: Los usos del WhatsApp
Authors: Lucio-López Luis Antonio , Prieto Quezada María Teresa , Carrillo Navarro José Claudio
Published: July 2018

In this article we present the results of an investigation regarding violence demonstration through WhatsApp among students of Higher Education, carried out in 11 educational programs. To learn the new types of mistreatment that faculty students enrolled in a public university in the city of Guadalajara, Jalisco, Mexico do and suffer through WhatsApp. 541 students were surveyed as part of a probabilistic sample of a population of 17 000 students, working with a 95% confidence level to estimate a proportion by means of a bilateral interval with a conservative approach obtaining an error limit of. 041 (4.1%).
Among the most relevant results, we found that 48% of the sample has felt uncomfortable and disgusted by pornographic photographs that their contacts have sent without their consent; the same happened with 37.4% of the sample of students to whom pornographic videos were sent. These types of messages constitute new abuses that offend those who receive them, which is also the case for 18.7% of the students who have been targets of seemingly harmless memes, however, those who appear in them suffer ridiculing. Another important finding was the one related to indifference and how it has become a new type of violence suffered by 77.8% of students.

Sexual harassment in institutions of higher education (IHE) is a problematic about which awareness and exploration is on the rise in Ecuador. However, there is a notorious lack of data to aid in estimating the magnitude of the phenomenon. This feeds into the idea that we are not dealing with a problem that needs to be prioritized. In this article, we describe the process for validating contents among experts for the construction of an instrument to measure the prevalence of this phenomenon. This process was carried out with the judgment of experts of the practices by the level of interrater agreement method. (Grant y Davis, 1996). We concluded that the content validation phase for experts is important for the development of instruments on sexual harassment because there are multiplicity of definitions and it isn’t clear the delimitation of the phenomenon. The panel of experts incorporated notions that are not contemplated in the literature. In reference to the hierarchy, emergent relationships in intersectional dynamics are included, something that cannot be left aside in the Ecuadorian context. The delimitation of practices related to content, effect, frequency, purpose, context and mode was also considered. Finally, the common approach favored having the same indicators to allow comparing results between universities in a feminist perspective.

Authors: Karale Anand , Shinde Kunaal K. , Damle Hemant
Published: July 2018

Background: An Intrauterine Fetal Demise (IUFD) is a major obstetrical catastrophe at any gestational age but the emotional pain and distress caused by this event increases in direct relation to the duration of pregnancy. The objective of the present study was to determine the incidence and possible causes of Intrauterine Fetal Demise (IUFD), and to determine preventive measures.Methods: Retrospective observational study was done from Jan 2015 to Dec 2017 at Smt. Kashibai Navale Medical College and General Hospital, Narhe, Pune. Inclusion criteria were all the pregnant women with IUFD delivered at the centre, at or above 24 weeks of gestation. The methodology followed were parameters of assessment for analysis were maternal age, parity, probable causes for IUFD, booked or unbooked cases, mode of delivery, maternal complications, and placental histopathology. Statistical data were analyzed using SPSS version 25.Results: The incidence of IUFD at authors’ hospital was 27/1000 live births. The IUFD rate was similar in maternal age <20years and >30years (p value 0.26). The incidence of IUFD increased with decreasing gestational age which was statistically significant (p value 0.001). IUFD incidence was higher in multiparous women compared to primiparous women (p value 0.036 with OR of 1.6 and 95% CI 1.02 to 2.54). The rate of IUFD was similar when sex of the baby was analyzed. 49.4% of fetuses had signs of maceration. The major cause of IUFD was severe preeclampsia (48.1%) which included HELLP syndrome, IUGR, Abruption. Maternal anemia (20.4%), GDM (3.8%), SLE (2.5%), APLA positive (2.5%), anhydramnios (6.3%) were some of the other important causes of IUFD.Conclusions: This study was conducted to determine the incidence of IUFD and associated maternal risk factors. By understanding the contributing factors, we can seek ways of avoiding recurrence of IUFD by proper antenatal care and early diagnosis of obstetric complications and its appropriate management.

Published: July 2018

A study was conducted to examine the physiological responses and yield of contrasting mungbean genotypes viz, MH 421, MH 318 and Basanti differing in their sensitivity to high temperature raised in earthen pots (30 cm diameter) filled with 5.5 kg of dune sand (Typic Torrispamments) under screen house conditions. High temperature stress was given by manipulating sowing dates i.e. normal (12th March, 2013) and late (29th March, 2013) sown. Samplings were done at 3 and 7 days after exposure (DAE) of temperature above 35°C at reproductive stage. Sampling below 35°C temperature was considered as control. High temperature resulted in decreased chlorophyll stability index, chlorophyll and carotenoid contents, relative stress injury and yield. Sensitive genotypes showed large reductions in aforementioned physiological traits. On the other hand, tolerant genotype (MH 421) maintained higher chlorophyll stability index, chlorophyll and carotenoid contents, relative stress injury and yield. After 7 days of exposure to high temperature under late sown, A significant decrease was noticed in genotypes MH 318 and Basanti.

The materials were planted in a randomized block design with three replications. The general combining ability and Specific combining ability effects were significant indicating the presence of both additive and non-additive types of gene actions. Heterosis was determined as the superiority over mid parent heterosis as well as better parent (HBP). Grain yield showed highly significant heterosis ranging from -36.29 to 8.77and relative heterosis ranged from -25.85 to 13.19 respectively.
Assessing the impact of agro-climatic factors on pod filling of grass pea
Authors: Ghosh Argha
Published: July 2018

Field experiments were conducted for two successive years with grass pea (cv. ‘Prateek’) sown on nine dates at weekly interval at Instructional Farm (22°58´ N, 88°31´ E), Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India to investigate the impact of agroclimatic factors on pod filling of grass pea. Results showed that pod filling percentage (PFP) increased with delay in sowing dates, attaining the highest value (96.7 %) in crop sown on 30th November, beyond which it decreased gradually with further delay in sowing. Maximum and minimum temperatures, morning and afternoon soil temperatures, recorded at 5, 15 and 30 cm soil depths, morning and afternoon vapour pressure deficits at pre-flowering phase exhibited negative association and contrarily, when prevailing during reproductive and pod development phases, these parameters demonstrated positive correlation with PFP. Temperature range during reproductive phase increased with delay in sowing dates and it exhibited significant positive correlation with PFP. As demonstrated by stepwise regression analysis, Accumulated photothermal unit (APTU) prevailing at maturity phase alone accounted for 67.4 % of the total variation in PFP and together with temperature range it explained 91.3 % variation. APTU, temperature range, afternoon vapour pressure deficit and afternoon soil temperature seem to be the critical agroclimatic variables influencing the pod filling percentage significantly.
Trust and Confidence in Institutions: Religious Beliefs and Educational Attainment
Authors: Miles Daniel , Rossi Maximo
Published: July 2018

The main objective of the paper is the analysis of intergenerational or cultural transmission of religious values during adolescence in order to explain interpersonal trust and confidence in institutions in adulthood. Trust and confidence in institutions outcomes are examined using the International Social Survey Program (ISSP) 2008 Religion III survey. Overall, the results are in line with previous literature: religious intensity and educational attainment are significantly and positively correlated with trust and confidence in institutions. When instrumental variables are used, the results suggest that religious engagement does not significantly explain interpersonal trust though it is significantly related to confidence in institutions.
Understanding the Impact of the Cultural Factors on Hospital Information System Acceptance: A Literature Review and Proposal of a New Model
Authors: Ouiame Benali Idrissi , Khalid Chafik , Omar Boubker
Published: July 2018

The behavioural intention to accept information system technologies remains an interesting research field for information system management specialists and researchers. However, the cultural dimension has rarely been treated by researchers in the healthcare context. This paper focuses on identifying the impact of national culture on users’ intention to accept the Hospital Information System in public healthcare establishments in Morocco. Thus, we propose a research model which is based on a strong literature review, taking into consideration the previous studies’ recommendations and limitations. The proposed model was developed through the extension of the Technology Acceptance Model (TAM) (Davis, 1989), by Hofstede’s cultural dimensions.

Authors: OSADEBE Patrick Uzo , NWABEZE Chukuka  Prince
Published: July 2018

The purpose of the study was to construct and
validate a Physics Aptitude Test (PAT) for senior secondary schools. The test
was designed primarily as an assessment tool for senior secondary school
students who have aptitude for Physics. Four research questions guided the
study. It was an instrumentation study designed to produce an assessment tool
for senior secondary school students. A sample of 200 students was randomly
selected through stratified random sampling technique. The data collected were
analysed to determine the validity of the test, item validity through item
analysis and reliability of the Physics Aptitude Test. The findings revealed
that the Physics Aptitude Test (PAT) has adequate face and content validities.
It is made up of 50 items. The difficulty and Discrimination indices were
appropriate because they are within the standard range of indices for the test.
Difficulty indices range from 0.30 to 0.70, Discrimination indices range from
.30 to 0.44. A reliability coefficient of 0.94 was obtained through Kuder
Richardson formula 20 as a measure of internal consistency. Since the Physics
Aptitude Test (PAT) was highly valid and reliable, it was recommended that it
should always be used as an assessment tool for determining the
aptitude of senior secondary school students in Physics.

Как сознание решает задачи научения и заучивания
Authors: Аллахвердов Виктор Михайлович
Published: July 2018

It is not an organism but consciousness, that studies, remembers andlearns to use the resources of the organism for solving the problems. Consciousness tries to guess the information that is kept in the organism’s memory or the actions that an organism is able for and that are essential for the achievement of the required effect. It verifies its hypotheses in the experience, but simultaneously tries to protect them from the disproof.Such conception has been illustrated by many experiments, in whichthree tendencies of subjects are proved: not to realize the thing that has once already been not realized; to repeat one’s own mistakes, first of all, in the cases of increasing successfulness of the acts; to raise the effectiveness of memorizing and learning by complicating irrelevant components of task.

Published: July 2018

Background & Objective: Notoginsenoside R1 (NGR1) is one of the main effective components
of Panax notoginseng.

Method:

Primary cortical neurons were harvested from neonatal rats and cultured to analyze the role
of NGR1 in neuronal growth and the effects of NGR1 on the Wnt/β-catenin signaling pathway. Following
treatment with NGR1, immunocytochemistry was used to detect expression of Tuj1 and
MAP2, and RT-qPCR was used to measure mRNA levels of key factors in the Wnt signaling pathway.

Results:

Results showed that NGR1 promotes growth of cultured neurons and significantly upregulates
mRNA levels of β-catenin, Dishevelled, and Frizzled. To further confirm whether NGR1
promoted cortical neuron growth via the Wnt/β-catenin signaling pathway, we knocked down β-
catenin mRNA by siRNA interference; following NGR1 treatment of β-catenin-knockdown neurons,
β-catenin mRNA levels increased significantly.

Conclusion:

In conclusion, these results demonstrate that NGR1 promotes growth of cultured cortical
neurons from the neonatal rat, possibly via the Wnt/β-catenin signaling pathway.
Patients’ Experiences of Web- and Mobile-Assisted Group Therapy for Depression and Implications of the Group Setting: Qualitative Follow-Up Study
Authors: Schuster Raphael , Sigl Sophia , Berger Thomas , Laireiter Anton-Rupert
Published: July 2018

Background

Blended group therapy combines group sessions with Web- and mobile-based treatment modules. Consequently, blended group therapy widens the choice within blended interventions at reasonable costs. This is the first qualitative study on blended group therapy.

Objective

The objective of this study was to investigate the patient-centered feasibility of blended group therapy for major depression, with special emphasis on the fit and dynamic interplay between face-to-face and internet-based elements.

Methods

A total of 22 patients who had a variety of experiences through participating in one of the two blended group therapy interventions were interviewed following a semistructured interview guide. In-depth interviews were analyzed by three trained psychologists, using thematic analysis and a rule-guided internet-based program (QCAmap). The transcript of the interviews (113,555 words) was reduced to 1081 coded units, with subsequent extraction of 16 themes.

Results

Web- and mobile-based elements were described as a treatment facilitator and motivator, increasing the salience and consolidation of cognitive behavioral therapy materials, resulting in in- and inter-session alignment to the treatment. Additionally, patients valued the option of intimate Web-based self-disclosure (by lateral patient-therapist communication), and therapists were provided with tools for between-session monitoring and reinforcement of exercising. In this context, group phenomena seemed to back up therapists’ efforts to increase treatment engagement. The dissonance because of noncompliance with Web-based tasks and the constriction of in-session group interaction were considered as possible negative effects. Finally, issues of tailoring and structure seemed to fulfill different preconditions compared with individual therapy.

Conclusions

Blended group therapy constitutes a structured and proactive approach to work with depression, and the integration of both modalities initiates a beneficial interplay. Results support the patient-centered value of blended group therapy and provide the first insight into blended group therapy’s role in fostering therapeutic treatment factors. However, potential negative effects should be considered carefully.
A expansão dos investimentos externos diretos chineses. O caso do setor energético brasileiro.
Authors: Schutte Giorgio Romano , Debone Victor Sant'Anna
Published: July 2018

A partir do final da década de 2000, houve um fluxo de investimento expressivo de estatais chinesas do setor energético para o Brasil, em particular para os segmentos de petróleo e elétrico. Esses fluxos corresponderam a movimentos mais amplos, que transformaram a China de importador líquido em exportador líquido de capital. Este artigo analisa a dinâmica dessa presença no Brasil no contexto da busca por uma nova inserção internacional por parte do governo chinês e da atuação internacional das empresas envolvidas. Os investimentos no setor de petróleo refletem principalmente uma dinâmica anterior de resource-seeking que continua atual devido à alta dependência da matriz energética de fontes fósseis no geral e de importação de petróleo em específico. De outro lado, os investimentos das estatais do setor elétrico correspondem a uma estratégia de exportação de capitais e à conquista de mercados mais recentes, baseadas na liderança tecnológica.

Mais do que porta de entra e saída de mercadorias (gateways), os portos são atores que geram fluxos – mercadorias, renda, trabalho – e cujas atividades impactam o meio ambiente de diversas formas. Por sua posição peculiar que atravessa as escalas local, nacional e global, os portos tanto agem quanto sofrem influência dessas diferentes escalas. Busca-se analisar se existiria um conjunto de regras e princípios capazes de contribuírem para um regime internacional voltado pra lidar com o setor portuário em um mundo globalizado e buscando a sustentabilidade das atividades desse setor. O estudo é analítico, com abordagem descritiva e qualitativa, com uso de referências bibliográficas e documentais. O trabalho demonstra que já há um regime estabelecido internacionalmente que vincula o comportamento dos portos à questão ambiental e promove a consciência ambiental portuária.
Quality improvement of the surface of laser micro welds by using a dual beam setup
Authors: Haeusler André , Hollatz Sören , Olowinsky Alexander , Gillner Arnold , Poprawe Reinhart
Published: July 2018

Laser micro welding on functional surfaces, for example, in medical engineering applications or in food industries, is gaining more and more importance. The ongoing development of high-brilliance laser beam sources allows processing of parts in the micron range with a minimum of energy input. Nonetheless, the welding process reduces the surface quality of the processed part. Every weld defect or irregularity in the molten pool has a direct impact on the surface roughness and therefore on the quality of the weld, which can cause increased expenditure for post-processing cleaning or damages on sensitive objects. By using a spatial power modulation – a linear feed with superposed circular motion – the molten pool dynamic can be influenced to achieve a more stable process, leading to a decreased surface roughness. Furthermore, an additional laser source can heat up and extend the end of the molten pool on the surface to decrease the dynamics of the molten pool even more. To achieve this, the second laser source is focused with a larger spot diameter to avoid a second keyhole generation and to create a longer molten pool with a shallower solidification front and a more stable fluid dynamic. As a further parameter, the output power of the continuously-emitting laser beam source can be modulated with a varied frequency and amplitude. This paper presents recent results on the influence of the spatial and temporal power modulation method in connection with a second laser source on the surface roughness during laser micro welding via laser measuring of the weld surface.
Comparative advantages in Polish export to the European Union ? food products vs selected groups of non-food products
Authors: Szczepaniak Iwona
Published: July 2018

Research background: Globalisation and economic integration are the reasons for which the competitiveness of economic entities is analysed more and more often in the context of their relations with the international market. One of the ways to assess the competitiveness of the Polish food sector is an analysis of comparative (relative) advantages in the export of this sector?s products.

Purpose of the article: The objective of this paper is to assess comparative advantages in Polish export of food products to the European Union against a background of selected groups of non-food products.

Methods: The study used the B. Balassa?s revealed comparative advantage (RCA) index. The study is preceded by a brief review of foreign trade results. The source of data was the WITS-Comtrade commercial database. The analysis was carried out at the level of the HS sections (in commodity terms). The research period covered the years 2003?2015.

Findings & Value added: In the years 2003?2015, export of food increased nearly six times and its import ? more than 4.5 times. The major partners of Poland as regards trade in food were the EU countries. The food sector was one of few sectors of the economy with the positive trade balance. Polish export to the EU was characterised by a diversified level of comparative advantages. From among 20 HS sections, in 2015 Poland had comparative advantages in export to the EU countries for products from 10 sections (2 food and 8 non-food). Those products accounted for 11% and 70% of Polish export to the EU, respectively. The development of Polish foreign trade in food products during the Polish membership in the EU as well as fairly high comparative advantages in the export of these products to the EU indicate the competitiveness and significant importance of the Polish food sector for the national economy.

Authors: Korcsmáros Enikő , Šimova Monika
Published: July 2018

Research background: Businesses are directly affected by the outside world, i.e. the business environment. Literature review lists a number of factors of the business environment affecting businesses. These factors may be oriented towards inputs, outputs, sales, or can be an instrument of regional policy. With regard to future development of businesses, it is crucial to identify which factor and to what extent can influence the operation of the business.

Purpose of the article: The main objective of the primary research was to provide a comprehensive assessment of how different factors influence enterprises of different economic sectors as well as help to verify the research question defined and formulate recommendations for future development of enterprises. The questionnaire survey to verify the research question was conducted on a sample of 496 small and medium-sized enterprises.

Methods: We chose quantitative method of ANOVA for processing the results of the survey, and we also set the limit of significant impact of different influence factors on the basis of analysed data of primary research, and the limit of significant impact.

Three new nitrosalicylatocopper(II) complexes have been prepared and characterized. Compounds of the composition Cu(5-NSal)2(2-ampy)2 (1), Cu(5-NSal)2(2-hmpy)2 (2) and Cu(3,5-DNSal)2(2-hmpy)2 (3), where 2-ampy = (2-aminomethyl)pyridine, 2-hmpy = (2-hydroxymethyl)pyridine, 5-NSal = 5-nitrosalicylate anion and 3,5-DNSal = 3,5-dinitrosalicylate anion, were characterized by elemental analyses, EPR and IR spectroscopy. EPR spectra are consistent with the dx2-y2ground electronic state. Spectral properties have shown “classic” monodentate coordination of 5-nitrosalicylate anion. Similarly, bonding mode of the 3,5‑dinitrosalicylate anion in (3) is assumed to be unidentate via the carboxyl group, which is surprising compared with the previously studied complex, where the preferred coordination via the phenolate group anion was observed.

In recent years, the prevalence of hookah smoking has increased worldwide, particularly in young people, which may have potentially serious consequences for their health. The aim of this study was to examine the factors associated with the consumption of hookah by high school students. The present study was conducted in the city of Novi Pazar, and students aged 17-19 years attending the following high schools were included: Medical School, Grammar School, Economic-Commerce School and Catering School. The study was designed as a case-control study. The cases were students who consumed nargile, while the control group consisted of students who had never smoked nargile. A special questionnaire was constructed for the purpose of this research, which was used to evaluate the opinions of adolescents on the consumption of nargile. Our research included a total of 270 seniors in high schools in Novi Pazar. The average age of the students was 18 years. The most important factors that may contribute to start using nargile were: previous consumption of nargile by older family members, divorced parents, and active smoking of cigarettes by other family members. Most students emphasized that hookah smoking is socially unacceptable form of behavior. Also, hookah smoker were neither more attractive nor popular. Nargile consumption is more common by adolescents whose parents are divorced, as well as by adolescents whose family members are smoking nargile or tobacco. The most common reason for nargile consumption among adolescents is a desire for relaxation.
AMMI and GGE Biplot for genotype × environment interaction: a medoid–based hierarchical cluster analysis approach for high–dimensional data
Authors: Neisse Anderson Cristiano , Kirch Jhessica Letícia , Hongyu Kuang
Published: July 2018

The presence of genotype-environment interaction (GEI) influences production making the selection of cultivars in a complex process. The two most used methods to analyze GEI and evaluate genotypes are AMMI and GGE Biplot, being used for the analysis of multi environment trials data (MET). Despite their different approaches, both models complement each other in order to strengthen decision making. However, both models are based on biplots, consequently, biplot-based interpretation doesn’t scale well beyond two-dimensional plots, which happens whenever the first two components don’t capture enough variation. This paper proposes an approach to such cases based on cluster analysis combined with the concept of medoids. It also applies AMMI and GGE Biplot to the adjusted data in order to compare both models. The data is provided by the International Maize and Wheat Improvement Center (CIMMYT) and comes from the 14th Semi-Arid Wheat Yield Trial (SAWYT), an experiment concerning 50 genotypes of spring bread wheat (Triticum aestivum) germplasm adapted to low rainfall. It was performed in 36 environments across 14 countries. The analysis provided 25 genotypes clusters and 6 environments clusters. Both models were equivalent for the data’s evaluation, permitting increased reliability in the selection of superior cultivars and test environments.

Published: July 2018

Biodegradability of pollution contained in examined industrial wastewater was assessed according to methodology based on Zahn-Wellens (OECD 302B) test. The following kinds of wastewater were examined: - metal industry wastewater from aluminium pressure foundry; - wastewater from industrial waste treatment processes, such as: filtration waste, chemical reagents, coolants, water emulsions, oil wastes and other industrial wastes, galvanising waste treatment processes sludge. Samples COD value decrease in the subsequent days of the experiment proves that organic substances contained in the examined wastewater undergo gradual biodegradability in aerobic conditions. The highest biodegradability degree of aluminium pressure foundry wastewater equal 65.7% was noted during 28 day of the experiment. However, the minimum biodegradability degree equal 80% after 13 aeration days, which in Zahn-Wellens test allows to determine the examined substance to be biodegradable, has not been achieved. Meanwhile, Zahn-Wellens test conducted for wastewater from industrial waste treatment processes showed that in the day 14 of the process, high (87.1%) organic substance degradation degree, measured with COD value decrease, was achieved. Further aeration of the samples did not increase biodegradability, which equalled 87.9% after 28 days.

Published: July 2018

In this paper, the mathematical model of shakedown optimization problem of limit analysis for the thin-wall metal frames under variable quasi-static loads is presented. Authors assume the elastic-plastic flexural buckling in one plane without lateral torsional buckling behavior of members on conditions of the ideal elastic-plastic behaviour of the frames materials. According to Eurocodes requirements, the features of these frames taking into account rigidity of their foundations are described. There is problem with definition equivalent uniform moment factors for frames under variable quasi-static loads, because moment diagram is not constant. Classification of joints by stiffness was analyzed. The cases when the conditions of rigidity are not satisfied were described. The variants of solving tasks for thin-wall metal frames have been developed, for which there is a discrepancy between the classification by stiffness of the column base and the initial design model. It’s demonstrated on the principle scheme of the iteration process. With the help of numerical example, the problems which deal with classification of joints by stiffness on the final step of the optimal design of the thin-wall metal frames were performed.

Published: July 2018

Contaminated and marginal lands are favourable place for biomass feedstock establishment, especially due to European Union directive 2009/28/EC. This strategy not only cover local demand for energy and heat but also can be valuable in those land phytomanagment. The second-generation perennial energy crop species are the most feasible for such purpose. We studied the impact of two different fertilizer treatments on plant physiological parameters associated with photosynthesis, heavy metals (HMs) and primary macronutrients accumulation in Sida hermaphrodita cultivated on HMs contaminated soil under field conditions. NPK fertilized plants showed the highest values of photosynthetic parameters at the beginning of growing season when compared to control and microbial inoculated plants. However, at the end of the growing season inoculated and control plants showed better photosynthetic performance than NPK treated. NPK fertilizer caused higher Cd and Zn shoot concentrations while microbial inoculation caused higher K and the lowest N and P concentrations in shoot. Due to Cd, Pb and Zn concentrations in plants which should not result in alleviation of photosynthetic apparatus efficiency and biomass production it could be summarize that Sida hermaphrodita is a suitable plant for cultivation on land contaminated with HMs under different fertilization regimes.

Published: July 2018

The paper provides an overview of the trend in the concentration of the total assets of banks in Croatia for the period from 2007 to 2016 with the aim of analysing and presenting the changes that occurred in the system. Also, the paper shows the theoretical framework of the indicators used in the research as well as the comparison of their obtained values. The data used to calculate the total assets concentration are taken from the Croatian National Bank. The concentration indices used in the study include the entropy measure, the Theil entropy, the Gini coefficient, the Pietra index, the Atkinson index and the coefficient of variation. The results indicate a very slight decrease in concentration over the past several years, while the coefficient of variation points to the heterogeneity of the system, as well as to inequalities among the banks, which are most evident in the size of banks assets.

Background

We analyzed cardiovascular inflammatory (C-reactive protein (CRP), interleukin 6 (IL-6)), haemostatic (homocysteine) risk markers in lean and obese patients at admission and acute hyperglicemic crisis (AHC) resolving, involving diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS).

Methods

In that context, we included group A: N = 20 obese, B: N=20 lean patients with DKA; C: N = l0 obese, D: N=10 lean patients with HHS; E: N = 15 obese, F: N=15 lean controls. CRP IL-6, homocysteine were determined by ELISA.

Results

Our results showed that CRP IL-6, and homocysteine levels decreased in all groups: (A: p<0.001; B: p<0.001, C: p<0.05; D: p<0.001 mg/L), (A: p<0.001 B: p<0.001, C: p<0.001, D: p<0.01 pg/mL), (A: p<0.001, B: p <0.001; C: p<0.05, D: p=0.001 μmol/L), respectively, at resolving AHC. However, CRP persisted higher (p<0.001, p<0.01), IL-6 lower (p<0.05, p<0.001), while homocysteine levels turned out to be similar to controls.

Conclusions

AHC is associated with increased inflammatory and hemostatic cardiovascular risk markers. Also, insulin therapy in AHC has had more pronounced favorable effect on IL-6 and homocystein than on CRP
