Authors: Toce Michael S , Farias Michael , Powell Andrew J , Daly Kevin P , Vargas Sara O , Burns Michele M
Published: June 2018

Many reports of marijuana-associated myocardial infarct (MI) are limited by incomplete evaluation of the toxicologic exposure, a lack of definitive anatomic findings, and the potential for comorbid coronary atherosclerosis inherent in an adult population. We report a 16-year-old adolescent boy who presented with chest pain after smoking marijuana and was found to have acute MI. Electrocardiogram showed diffuse ST-segment elevations. Exhaustive toxicologic testing confirmed the presence of Δ-9-tetrahydrocannabinol metabolite and ruled out other drugs of abuse. Echocardiography demonstrated moderate global left ventricular systolic dysfunction. Coronary angiography demonstrated no focal coronary lesions or obstruction. Right ventricular septal endomyocardial samples biopsied 36 hours after the onset of pain showed a subendocardial acute MI with a sparse neutrophilic infiltrate. One month after the event, magnetic resonance imaging showed a severely dilated left ventricle and moderately to severely depressed global systolic function. Late gadolinium enhancement consistent with myocardial fibrosis was seen in nearly all myocardial segments. Our unusually well-documented findings strengthen the potential association between marijuana and MI. Furthermore, we demonstrate a disease distribution supporting a process that affects the coronary circulation globally, likely at the distal, small-vessel level.

Published: June 2018

Background

As body fat composition and metabolism differ between men and women, we evaluated sex-related differences in the association among epicardial adipose tissue (EAT), secretome profile, and myocardial function of subjects with suspected metabolic syndrome.

Methods

We evaluated 277 participants (men, n = 140; 56.1 ± 4.7 years) who underwent conventional echocardiography and two-dimensional speckle tracking from the Seoul Metabolic Syndrome cohort. EAT was measured from the right ventricular free wall perpendicular to the aortic annulus at end systole. Global longitudinal strain (GLS) was obtained from 18 apical segments. Apolipoprotein A1, apolipoprotein B, adiponectin, and high-sensitivity C-reactive protein (hs-CRP) levels were measured using immunoturbidimetry assay.

Results

Mean age, body mass index, and hs-CRP level did not differ by sex. Waist circumference, fasting blood glucose level, and triglyceride/high-density lipoprotein cholesterol ratio were higher, and apolipoprotein AI and adiponectin levels were lower in men. No significant difference in mean EAT thickness was found (7.02 ± 1.81 vs. 7.13 ± 1.70 mm, p = 0.613). Men had a higher left ventricular (LV) mass index and lower GLS. EAT thickness was associated with hs-CRP level in men alone (ß = 0.206, p = 0.015). LV mass index (ß = 2.311, p = 0.037) and function represented by e′ (ß = − 0.279, p = 0.001) and GLS (ß = − 0.332, p < 0.001) were independently associated with EAT thickness in men alone.

Conclusions

In middle-aged subjects with suspected metabolic syndrome, EAT was associated with inflammation represented by hs-CRP level, LV mass, and subclinical myocardial dysfunction only in men, suggesting that the inflammatory activity of EAT induced myocardial remodeling and dysfunction in middle-aged subjects but was attenuated in women.

Authors: Chaves Silva Rebeca Silvestre , Passos Tatiana Uchôa
Published: July 2018

Introdução: Uma alimentação adequada na fase pré-escolar é essencial, visto que os hábitos alimentares começam a ser consolidados nessa etapa. Objetivo: Verificar a adequação dos cardápios da alimentação escolar em creches municipais de Fortaleza, Ceará. Metodologia: A partir dos per capitas, os alimentos foram desmembrados em ingredientes separados por grupos alimentares da Pirâmide Alimentar Infantil e quantificados em frações conforme as porções do Guia Alimentar para a População Brasileira. Comparou-se a média de porções de cada módulo de cardápios com a recomendação da Pirâmide Alimentar Infantil. Consideraram-se adequados os grupos alimentares que atingissem 70% das porções, visto que o Programa Nacional de Alimentação Escolar (PNAE) preconiza atender a 70% das necessidades nutricionais de crianças matriculadas em tempo integral. Resultados e Discussão: Foram encontradas as seguintes médias relativas aos grupos alimentares: cereais 2,3±0,2; verduras e legumes 0,3±0,1; frutas 1,0±0,1; leite 0,8±0,2; carnes 0,5±0,0; feijões 0,6±0,2; óleos 0,2±0,0; e açúcar 0,4±0,2. O grupo de verduras e legumes apresentou o menor percentual (10,0%) de adequação, já o de feijões (60,0%) e o de cereais (46,0%), os maiores resultados. Conclusão: Todas as porções estavam abaixo da recomendação da Pirâmide Alimentar Infantil, não atendendo também às diretrizes do PNAE. Portanto, sugere-se que mudanças nos cardápios sejam realizadas, a fim de se adequar melhor às recomendações propostas, contribuindo, assim, para a promoção da saúde das crianças.

The Effect of High-Intensity Aerobic Exercise on the Pulmonary Function among Inactive Male Individuals
Authors: Rawashdeh Arwa , Alnawaiseh Nedal
Published: June 2018

A spirometer is an important instrument in the assessment of the lung functions. FVC, FEV1, MVV and ratio of FEV1/FVC are indicators of strong respiratory function that deteriorate due to a sedentary lifestyle. Prolonged aerobic exercises are thought to improve aerobic capacity and to have a favorable effect on lung function. Thus, the main aim of this study was to investigate the effect of such aerobic exercise for three weeks, specifically continuous treadmill running, on lung function (FVC, FEV1, ratio of FEV1/FVC, and MVV) in inactive yet healthy male individuals. For this study, 72 inactive male individuals were given a pulmonary function test. The test was performed three times for each session (starting with five minutes and increasing by ten minutes every three sessions, up to a maximum of 25 minutes), and its mean value was used for analysis. Exercise was performed three days a week for three weeks. The Wilcoxon test was done to determine changes pre- to post-test. Repeated-measure analyses were used to compare the changes of pulmonary values between high-intensity sessions. Spearman correlation rho was conducted to assess association between MVV, FVC, and FEV1, and the Friedman test was used to compare the mean ratio of FEV1/FVC before and after exercise of different intensities. FEV1, MVV and a ratio of FEV1/FVC were significantly improved after high-intensity aerobic exercise of different intensities. In addition positive relation of MVV with FEV1 improvements was found. In contrast, there were insignificant improvements in FVC before and after exercise of different intensities and with no positive relation of MVV improvements. The improvements in MVV could reflect subtle changes in lung function or airway reactivity not detected by the FVC test. In addition, higher exercise intensity or longer duration may be needed to affect other lung function parameters like MVV, FEV1 and FEV1/FVC. Thus our results demonstrate that high-intensity aerobic exercise on the treadmill has a positive effect on the pulmonary function of inactive healthy subjects.

Published: June 2018

Maxillofacial defects cause impact on oral health related quality of life (OHRQol) including limitations in functional activities, communication, social interaction, and intimacy. The obturator prosthesis is commonly used as an effective means for rehabilitating maxillectomy patients. The purpose of this study was to investigate impact of definitive obturator prosthesis on oral health related quality of life. In the period between 2015 -2017, a total of twenty five (25) patients with acquired maxillary defects based on Okay classification have been selected and rehabilitated with definitive obturator prostheses .The OHRQol was measured using the Oral Health Impact Profile (OHIP-Edent-19) and Obturator functioning scale (OFS) with standardized questionnaire after 2 weeks & 3months of prosthesis function.To find the significant difference between the bivariate samples in Paired groups the Wilcoxon signed rank test was used. With respect to oral health impact profile –Edent 19 scale, the mean functional limitation score were 6.72 and 5.20 indicates that there is significant improvement in chewing performance after 2 weeks and 3 months of prosthesis function. Significant improvement in oral health impact profile was noticed in physical (M = 5.84, 4.88), Psychological (M=4.84, 3.96) and social disabilities (M=5.28, 4.16). Similarly, when observed with Obturator functioning scale, significant improvement were noted in chewing performance phonetics, appearance and miscellaneous aspects. Analysing the OHIP –Edent-19 scale and obturator functioning scale (OFS-15), statistically significant differences (Wilcoxon rank test p value = 0.0005) were observed. Within the limits of this study, it can be concluded that highly positive correlation exists between definitive obturator prostheses and oral health related quality of life (OHRQol).

Published: June 2018

This in vitro study aimed to assess and compare premolars cuspal deflection that restored with different bulk fill resin materials types (SonicFillTM2, Beautifil Bulk Fill restorative, and FiltekTM Bulk Fill posterior restorative) to those incrementally restored group with conventional composite restorations (low shrinkage universal Tetric Evoceram). A total of 40 intact human maxillary first premolars were prepared into large MOD. Then teeth were randomly classified into four groups (n=10 for each group) according to restorative materials as following: Group A: Teeth were restored with Sonic FillTM2 composite, Group B: restored with Beautifil Bulk Fill restorative material, Group C: Teeth were restored with Filtek BulkTM Fill posterior restorative, and Group D: Teeth were restored with Universal Tetric Evo Ceram®. Digital microscope was used to measure intercuspal distance between two index reference points on the tips of the cusps before preparation, after preparation, and 15minutes after completion of restorations. The differences registered as cuspal deflection. All teeth were exposed to inward cuspal deflection after restoration and all groups that restored with bulk fill restoration reported lower cuspal deflection in compared to group D that restored with conventional composite in layering technique. Beautifil Bulk Fill restorative produced significantly greater cuspal deflection than other bulk fill groups. The study concluded that the use of new bulk fill restorative materials might reduce amount of cuspal deflection significantly. However, type of bulk fill restorative materials also influenced on amount of cuspal deflection so restoration with Sonic Fill™2 composite and Filtek Bulk™ Fill posterior reported lower cuspal deflection than Beautifil Bulk Fill restorative material.

Published: June 2018

Digital watermarking is one of the most efficient techniques to provide the highest secureness to the transmission of data like images or videos over the internet. Quite over the medical data which incorporates the EHR (Electronic Health Record) and medical images and conjointly the military data are crucial whose protection and privacy is extremely a lot of essential issues. To secure this data, the Digital watermarking plays a major role so that it will guarantee authentication, integrity, confidentiality and reliability. In the case of medical images, even a small change or modifications are strictly prohibited as it might lead to the incorrect diagnosis of the disease. Therefore, securing medical image is extremely essential. So as to provide high security for each patient’s data and also the various medical scanning images, we can employ the Digital Water Marking (DWM) technique. The DWM technique may be implemented in two ways: Spatial domain technique and Frequency domain technique. Although the spatial implementation is extremely straightforward and a very simple method, most of the implementations are done using frequency or transform/remodel domain strategies since it provides additional details and high effectiveness. The DWM may be implemented using numerous transform/remodel techniques like Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), also with the combination of these remodel techniques. Nowadays the work is also extended using a combination of transforming/remodel and spatial domain techniques. In this article the Digital Water Marking is being implemented by employing a combination of a transform technique DWT and a spatial domain technique SVD to provide security to the medical images and also the system efficiency is checked for numerous attacks.

Published: June 2018

Growth, yield, protein content, net photosynthetic rates, stomatal conductance and amino acid profiles were determined in wheat (Triticum aestivum L) plants in response to 50 ppb O3 during the growing season. This concentration is similar to the concentrations of O3 in ambient air. O3 decreased photosynthetic rates (24%) and stomatal conductance (25%), which were reflected in lower growth and yield in terms of number of grains and 100 grain weight. Scanning electron microscopy showed a collapse in the epidermal cells adjacent to stomata that led to stomatal closure and consequently reductions in stomatal conductance. The significance of O3-induced impairment of growth, yield and alteration in amino acid contents are discussed. To the best of our knowledge, this is the first study reporting impact of ozone on protein content, amino acids and yield of wheat in Saudi Arabia.

After obtaining the permission from the Institutional Ethical Committee (IAEC) Wistar albino rats were randomly selected and divided into 4 groups. The animals were fasted and deprived of food and water 20hrs prior to the experiment. On the day of experimentation, Group 1 negative control received Normal saline (25ml/kg), Group 2 positive control received Furosemide 20mg/kg body weight, and Group 3 received ethanonic extract of delonix regia 100mg/kg and Group 4 received ethanonic extract of delonix regia 200 mg/kg. Delonix regia increase the excretion of sodium and water at the dose of 100mg/kg and 200mg/kg of body weight. The diuretic index is 5.93 and 6.45 at 100mg/kg and 200mg/kg of delonix regia respectively. The diuretic activity if delonix regia 100mg/kg is 0.61 and 0.67 at dose 200mg/kg, which is more than that of negative control but less when compared to positive control. Ethanonic extract of Delonix regia showed significant diuretic activity at both 100mg/kg and 200mg/kg doses.

Published: June 2018

Systemic inflammation describes certain metabolic alterations which are mediated by inflammatory cytokines. Theses occur essentially as a defensive body response towards offending agents such as surplus nutrient staffs. Our aim is to find out the role of inulin as a protective agent against metabolic inflammation. Twenty eight type 2 diabetic females were subjected to the estimation of their serum high sensitivity C-reactive protein, lipopolysaccharides, tumor necrosis factor alpha, adiponectin and HOMA-IR test before and after three weeks of inulin ingestion. There was a significant drop in the level of serum high sensitivity C-reactive protein, lipopolysaccharides, tumor necrosis factor alpha, HOMA-IR and a non-significant rise in serum adiponectin after inulin ingestion. In summary inulin can act as a useful protective agent in systemic inflammation.

Published: June 2018

Radiography in dentistry is commonly used in modern dental health care. It acts as a diagnostic tool in identifying the physical condition of the patients. However the use of dental radiography should be carefully managed since it can cause some side effects toward normal cells and tissues especially in growing children. To assess the knowledge, attitude and practice of undergraduate dental students on radiation exposure protection for pedodontic patients. A self-administered questionnaire consists of 13 questions with both ‘yes’,’no’ and multiple choice pattern was prepared to obtain information about knowledge, attitude and practice on radiation exposure protection for pedodontic patients.A total of 100 dental students were chosen as the participants. The questionnaires were assessed by manual survey. The use of dental radiograph has bee significantly enhanced over the years for better diagnosis and treatment planning .Tough the application of has been increased, there is an increased risk for unwanted exposure for both patient and operator also. In this current study, conducted among third year and final year dental students, we observed that the students are able to take proper radiograph with unnecessary retakes with years of study and practice. To conclude, it can be noted that the final year dental students were much more knowledgeable in using radiograph judicially compared to the other group of participants which belong to third year dental students. However, in terms of practise both third year and final year dental students irrespective of year of study do not follow radiation protection measures even though they were aware of it.

Published: June 2018

Introduction

Parathyroidectomy is considered to be a safe procedure with low morbidity. However, while this is true for primary hyperparathyroidism, whether it applies to tertiary disease is not so well documented. The aim of this study was to assess the morbidity of surgery for tertiary hyperparathyroidism compared with primary disease and to establish whether there are predictive factors for poor outcomes.

Methods

Data for patients subjected to parathyroidectomy during the period 2007–2015 were retrospectively analysed from a prospectively collected database. Patient age, sex, American Society of Anesthesiologists (ASA) score, renal status, extent of operation and indications for surgery were examined. The complication and mortality rate were compared and independent predictors of outcome were examined.

Results

A total of 1079 patients were scheduled for a parathyroidectomy during the study period of whom 158 for renal related hyperparathyroidism (renal group) and 921 for primary disease (non-renal group). There was a significantly higher complication rate in the renal parathyroid group, including a higher mortality (1.3% vs 0.1%, P = 0.011), overall complication rate (7.0% vs 2.3%, P = 0.001), surgery related complication rate (4.4% vs 1.7%, P = 0.03) and systemic complication rate (2.5% vs 0.4%, P = 0.005). In patients with ASA score ≤ 2 reoperative surgery (OR 9.25, 95% confidence interval, CI 1.41–60.75), male sex (OR 4.12, 95% CI 1.46–11.63) and renal impairment were (OR 5.86, 95% CI 1.65–20.78) were predictors of worse outcomes. In patients with ASA score ≥3 renal impairment, in addition to other variables, were not predictors of complications.

Conclusions

Parathyroidectomy in renal-related disease is associated with a significantly higher risk of morbidity and mortality compared with primary hyperparathyroidism.

Adsorption Of Cs+ and IO3− Ions by Pseudoboehmite Before and After the Decomposition of Citrate Adsorbed on Its Surface
Authors: Kawano Motoharu , Yamada Eri
Published: June 2018

Citrate is distributed widely in the Earth’s surface environments as a biological product released by microbes and plants. Citrate is also often used as a chelating agent for the selective dissolution of iron coatings and free iron oxides in soils. Adsorption experiments of Cs+ and IO3− before and after the complexation of citrate with the pseudoboehmite surface were conducted to evaluate the effects of citrate on the adsorption of these ions on the surface of pseudoboehmite. Additional adsorption experiments of Cs+ and IO3− after the decomposition of citrate adsorbed on the pseudoboehmite surface were also performed to confirm the recovery of the original surface properties. Citrate decomposition was carried out by means of 10% H2O2 treatments at 75°C and pH 5, 7, and 9. The results indicated that citrate complexation decreased remarkably the adsorption of both Cs+ and IO3− in the pH range 3–10, which was due to a decrease in the number of active charged sites available for adsorption of these ions. Decomposition of citrate adsorbed on the pseudoboehmite surface was found to be complete after three rounds of treatment with 10% H2O2 at 75°C and pH > 7. After the decomposition of citrate adsorbed on the pseudoboehmite surface, the adsorption of both Cs+ and IO3− was restored completely to the initial amounts before citrate complexation, and the inhibition effect of citrate on the adsorption of these ions disappeared under all pH conditions.
Intergenerational dialogue: Connecting youth and older adults in urban spaces through community-based forum theatre
Authors: Parker Christina
Published: June 2018

Understanding generational diversity has important implications for building capacities for developing healthy intergenerational relations and social cohesion, and for challenging oppression. Preparing young people in urban communities to understand and empathize with older adults could have lasting benefits for engaging community members and families to come together to transform culturally divided urban spaces. This qualitative research project drew on arts-based approaches to examine how dialogue between youth and older adults in a community-based theatre education program sought to lessen intergenerational and intercultural divides. While forum theatre is widely used to challenge oppression, this article considers how it could also lead to further exclusion of marginalized voices if both facilitators and participants are inadequately prepared to engage in dialogue. It offers practical suggestions for community educators in diverse urban settings, particularly in the use and application of the arts.

Authors: Vlček Daniel , Caha Vojtěch , Ševeček Martin
Published: July 2018

This paper deals with Post-CHF (critical heat flux) heat transfer with the focus on different regimes of film boiling. The new thermal-hydraulic code TUBE 2.0 is presented. This code uses the equation of energy conservation and predefined correlations to establish wall temperature, the departure of nucleate boiling ratio as well as other parameters of cooling in a simple geometry - an isolated channel. With experimental data of inverted annular film boiling from Stewart, the best-performing correlation for calculation of post-CHF heat transfer in the channel was determined. Finally, the new presented code TUBE 2.0 and subchannel code SUBCAL owned by Chemcomex a.s. are compared using results of various experiments conducted by Becker. Data from Stewart could not be used because of inability to predict the onset of boiling crisis with several correlations.

This area of scientific and methodological research and development is relevant because of the need for searching reserves for the advancement of territories based on the inventory taking and the fullest use of available resource opportunities. In this regard, the article has improved the organizational and methodological approaches to conduct monitoring as a part of a comprehensive system diagnostics of peripheral territories of the region based on analytical criteria for socio-economic and tourist potential. The authors formulated a semantic and economic interpretation of the findings and outlined the prospects for using them when forming socio-economic development policy of regions and their economy sectors. The scientific novelty of the present article consists in development of elements of system research and diagnostic methodology with respect to development potential of peripheral areas, based on the analysis of the socio-economic and tourism factors. The combination of results and recommendations represents a contribution to the scientific substantiation of spatial and sectoral analysis.

The study aims to analyze the innovation strategy impact on improvement of man-made tourist visit in Indonesia. Nowadays, man-made tourism is very popular for society as an alternative family tourism for entertainment, education and refreshing. The type of study uses a qualitative approach. Data collection techniques are conducted by in-depth interviews with man-made tourism actors in Indonesia, especially at Jatim Park Batu Malang, East Java Province, Taman Mini Indonesia Indah, Jakarta Province, Ragunan Zoo, Jakarta Province and Ancol, Jakarta Province, Indonesia. The researcher team also conducted data collection through photographs and records in the field. The study result recommends that man-made tourism requires innovative, effective, efficient and not easily imitated innovation strategies to increase the number of tourists so they can compete with other tourism such as natural and cultural tourism. Man-made tourism business actors need to manage well and professionally so the man-made tourism visitors will increase in the long term.
Georg Kerschensteiner y la escuela del trabajo: su introducción en España en el primer tercio del siglo XX a través de la figura de Lorenzo Luzuriaga
Authors: Valbuena Canet Cecilia
Published: June 2018

Esta investigación nace con el objetivo de analizar la introducción en España de la idea de la Escuela del Trabajo (Arbeitsschule) desarrollada por Georg Kerschsensteiner en Alemania, cuya característica principal fue la de convertir el «trabajo» en el punto de partida en torno al cual se articulaban todas las materias de enseñanza, dotando a las actividades realizadas en la escuela de un carácter social además de formativo. Lorenzo Luzuriaga, como miembro de la Liga Internacional de Educación Nueva, incorpora el ideario de Kerschensteiner a su pensamiento pedagógico y tratará de introducirlo en España. Para llevar a cabo este trabajo se ha realizado una intensa labor de análisis, tanto de las obras traducidas del propio Kerschensteiner como de otro tipo de fuentes, entre las que destaca la prensa pedagógica española del momento, fundamentalmente la Revista de Pedagogía. La elección de esta publicación no es casual, ni tampoco se basa en su consabida importancia en el contexto pedagógico en el que surge, sino que resulta del mismo proceso de análisis de la misma, que, a medida que se fue realizando, puso de manifiesto el papel de su director y fundador, Lorenzo Luzuriaga, como principal introductor de la pedagogía de Kerschensteiner en España.

Authors: Fiscella Alessio , Pucci Patrizia , Zhang Binlin
Published: June 2018

This paper deals with the existence of nontrivial solutions for critical Hardy–Schrödinger–Kirchhoff
systems driven by the fractional p-Laplacian operator. Existence is derived
as an application of the mountain pass theorem and the Ekeland variational principle.
The main features and novelty of the paper are the presence of the Hardy terms as well as critical nonlinearities.
Zuwanderung und globale Migration als Herausforderung der Demokratie
Authors: Münkler Herfried
Published: June 2018

Warum und unter welchen Umständen schotten sich gerade Demokratien gegen Zuwanderung ab? Eine solche Tendenz ist nicht neu, sondern lässt sich bereits an der attischen Demokratie er Antike beobachten. Neu dagegen ist, dass die reichen Gesellschaften heute auf Zuwanderung angewiesen sind, wenn sie nicht schrumpfen sollen und das Wohlstandsniveau erhalten bleiben soll. Dieser längerfristige Aspekt kommt jedoch in einer auf kurzfristige Politik angelegtenDebatte selten zum Tragen. Freilich gibt es eine Grenze sozio-politischer Integration, die in der Erosion von Vertrautheit und Vertrauen liegt. Wo diese Grenze liegt, hängt indes von der Integrationskraft einer Gesellschaft ab.
Hat die offene Gesellschaft eine Zukunft?
Authors: Wilkens Andre
Published: June 2018

Die Kritik der etablierten Verhältnisse darf nicht zum Privileg der Neurechten werden. Am Setzen von eigenen Themen und an der Lösungskapazität für real existierende Probleme wird sich entscheiden, ob die offene Gesellschaft eine Zukunft hat oder nicht. Es braucht eine Dialektik des Erhaltens und des radikalen Veränderns – des Erhaltens vom Wertegerüst der offenen Gesellschaft und der Entwicklung radikal neuer Entwürfe des gesellschaftlichen Zusammenlebens, die den wirtschaftlichen und technologischen Entwicklungen des 21. Jahrhunderts entsprechen. Die offene Gesellschaft ist nicht einfach Status quo. Sie hat eine Zukunft jenseits der real existierenden Verhältnisse. Sie ist im wahrsten und kreativen Sinne Entwicklungsland.
Zivilgesellschaft in der sozialökologischen Krise
Authors: Adloff Frank
Published: June 2018

Welche Auswege aus der sozialökologischen Krise lassen sich aktuell identifizieren? Die meisten Nachhaltigkeitsansätze versuchen, ökologische Ressourcenschonung mit ökonomischer Modernisierung und insbesondere mit Wirtschaftswachstum zu versöhnen. Der Beitrag diskutiert hiervon abweichend eine radikale Transformationsperspektive, die davon ausgeht, dass eine nachhaltige Gesellschaft nur eine Postwachstumsgesellschaft sein kann. Ideen von Postwachstum und zivilgesellschaftliche Trägergruppen werden identifiziert und gefragt, welche Risiken und Umsetzungschancen ein solches Transformationskonzept mit sich bringen könnte.
Technik und Demokratie
Authors: Saretzki Thomas
Published: June 2018

Der wissenschaftlich-technische Wandel bringt spezifische Herausforderungen für die Demokratie mit sich. In der Bundesrepublik Deutschland gab es zwar eine ganze Reihe von Technisierungsprozessen, die Anlass zu Protesten geliefert haben. Aber bisher hat nur die Nutzung der Kerntechnik zu Konflikten geführt, die im Sinne einer Krise der Demokratie interpretiert werden können. Für eine zukunftsorientierte Krisenprävention könnte eine Lehre aus diesen Erfahrungen darin bestehen, in der Technologie- und Innovationspolitik kompetente zivilgesellschaftliche Akteure kontinuierlich an der Meinungs- und Willensbildung von demokratischen Institutionen wie dem Parlament zu beteiligen.
Gefährden bestehende soziale Defizite in der Europäischen Union die Demokratie?
Authors: Fojkar Thiemo , Backfisch Peter
Published: June 2018

Die Autoren geben einen historischen Überblick über die beispiellose Erfolgsgeschichte der Europäischen Union. Die Menschen können dadurch auf eine mehr als siebzigjährige Friedensphase zurückschauen. Auch der Wohlstand hat stetig zugenommen. Inzwischen ist aber eine gefährliche Schieflage eingetreten. Armut, Arbeitslosigkeit, Einschnitte in die sozialen Sicherungssysteme auch der Brexit sind dafür Symptome. Die Autoren sehen deshalb Gefahren für unsere demokratische Kultur in Europa und versuchen, Lösungsvorschläge aufzuzeigen.
Asymptotic expansion of holonomy
Authors: Grong Erlend , Pansu Pierre
Published: June 2018

Given a principal bundle with a connection, we look for an asymptotic expansion of the holonomy of a loop in terms of its length. This length is defined relative to some Riemannian or sub-Riemannian structure. We are able to give an asymptotic formula that is independent of choice of gauge. We also show how our results from sub-Riemannian geometry can give improved approximations for the case of studying expansions of holonomy of principal bundles over the Euclidean space.
The Impact of Financial Development on Energy Demand in Transition Economies
Authors: Oskenbayev Yessengali , Issabayev Murat
Published: June 2018

Financial development has proven to be one of the major determinants of energy consumption. Although, the U-curve relationship between financial development and energy demand is frequently featured in the literature, there is not much discussion of nonlinear relationships between financial development and energy consumption. In this study we investigated the nexus of these two phenomena in transitional economy countries over the period from 1990 to 2011 employing a Systems-GMM model and the panel cointegration method. The empirical results reveal strong evidence of an inverse U-shaped pattern for the impacts of financial development on energy consumption. The net total effect of financial development on energy demand implies that a one standard deviation increase in financial depth induces a decrease in energy consumption by 0.09 kg of oil equivalent per capita. We also found evidence of Granger causality of financial development on energy demand. The existence of a linkage between the two has been suggested in an earlier study conducted by Coban and Topcu [26]. Although they established the nonlinear nature of the relationship between financial development and energy consumption, this was only apparent after they divided the sample between older and newer EU members. In this respect the effect of financial development on energy consumption is rather dubious because that study used a dynamic panel data model for 15 countries over the period from 1990 to 2011.
Carbohydrate content of black liquor and precipitated lignin at different ionic strengths in flow-through kraft cooking
Authors: Dang Binh T.T. , Brelid Harald , Theliander Hans
Published: June 2018

The influence of sodium ion concentration [Na+] on the dissolution of carbohydrates in black liquor (BL) during flow-through kraft cooking of Scots pine wood meal (Pinus sylvestris) was studied. Fractions of BL were collected at different times and the carbohydrate content of the various fractions was analysed. Lignin was precipitated from the BL by lowering the pH, and the carbohydrate content of the precipitated lignins (Lprec) was also examined. The molecular weight distribution (MWD) of the Lprec samples was analysed. Xylose (Xyl) was found to be the most predominant sugar in BL aside from arabinose (Ara) and galactose (Gal), while the amounts of these sugars decreased with increasing levels of [Na+] in the cooking liquor. The minor amounts of mannose (Man) found in BL was not influenced by the [Na+]. The effects of NaCl and Na2CO3 on the carbohydrate dissolution were similar, but slightly lower concentrations of Ara and Xyl were found in the case of NaCl application. All of the Lprec samples contained some carbohydrate residues, the contents of which increased with increasing cooking time and decreased with higher [Na+]. It can be concluded that arabinoglucuronoxylan (AGX) along with arabinogalactans (AG) and arabinan, are covalently linked to lignin. The glucose (Glc) residue detected in Lprec may originate from 1,3-β-glucan linked to lignin.
Direct production of lignin nanoparticles (LNPs) from wood using p-toluenesulfonic acid in an aqueous system at 80°C: characterization of LNP morphology, size, and surface charge

Lignin nanoparticles (LNPs) from renewable lignocelluloses can be a valuable building block for a variety of applications and could contribute to the economic development in rural agricultural communities. Current technologies for producing LNPs are not cost effective and use toxic solvents. In this study, LNPs were produced by fractionating poplar wood at ≤80°C with a recyclable hydrotrope p-toluenesulfonic acid (p-TsOH) in an aqueous system. The dissolved lignin was separated as LNPs simply by diluting the spent liquor (SL) to the minimal hydrotrope concentration (HCmin) of 11.5%. The p-TsOH, a solid acid, can be easily recycled by re-concentrating the diluted SL after lignin separation. The LNP size, morphology, and surface charge were controlled by the dilution ratio, speed, pH, and ionic strength of the LNP sol. The LNPs were analyzed by dynamic light scattering (DLS) and found to be fairly stable in terms of mean particle size and surface charge over a period of 2 weeks. Fractionation conditions also affected LNP properties.
