A Study of Compost as an Adsorbent for Congo Red Dye Removal Process
Authors: Kristanto Gabriel Andari , Raindra Lamurvie Ariessyawtra , Koven William 
Published: May 2018

The human population continues to grow annually, and so does the number of textile industries. In textile industry, synthetic dye is one of the most polluting substance in its wastewate which the conventional treatment processes are usually ineffective. Another option is using activated carbon to remove the dye, but carbon is an expensive material. It is is interesting that material that is rich in carbon, such as compost, may become an alternative solution. The objective of the present study was to assess the capability of compost in treating wastewater dye by determining the optimum compost dosage, particle size, and column height, while considering dye percentage removal and adsoprtion capacity. The optimum compost dosage was 8g/L and the optimum particle size was 1–2 mm in treating the 200 ppm Congo Red dye molecule, resulting in 20.49% removal and a 5.33 mg/g adsorption capacity. The optimum compost column height was 60 cm with 90% removal, and the adsorption capacity was 0.38 mg/g. The dye molecule wore off tthe compost, therefore fresh compost must be introduced in order to maintain its percentage removal level. The compatibility of isotherm model developed in this study with the Freundlich model is similar with previous studies. Keywords: compost; congo red dye;adsorbent, batch, column
Short Sale Constraints, Correlation and Market Efficiency
Authors: Giannikos Christos , Gousgounis Eleni 
Published: May 2018

Abstract
This paper models a market where short sales are prohibited and investors have heterogeneous beliefs on asset values. We show that short sale constraints may cause overpricing, the magnitude of which depends on not only investors’ opinion dispersion on the value of the particular asset, but also on its correlation to other assets, as well as, the investors’ opinion dispersion for the values of those other assets.
A Zariski--Nagata theorem for smooth ℤ-algebras
Authors: De Stefani Alessandro , Grifo Eloísa , Jeffries Jack 
Published: May 2018

Abstract
In a polynomial ring over a perfect field, the symbolic powers of a prime ideal can be described via differential operators: a classical result by Zariski and Nagata says that the n-th symbolic power of a given prime ideal consists of the elements that vanish up to order n on the corresponding variety. However, this description fails in mixed characteristic. In this paper, we use p-derivations, a notion due to Buium and Joyal, to define a new kind of differential powers in mixed characteristic, and prove that this new object does coincide with the symbolic powers of prime ideals. This seems to be the first application of p-derivations to commutative algebra.
Controlling for Import Price Effects in Civil War Regressions
Authors: Janus Thorsten , Riera-Crichton Daniel 
Published: May 2018

Abstract
Several studies estimate the effects of commodity export prices on economic outcomes, such as conflict and democratic transitions. In this note, we argue that it is important to control for the effects of import prices due to two reasons. First, economic theory predicts that both import and export prices affect the economy’s performance, which can, in turn, affect its conflict propensity. Second, the facts that import prices might affect the conflict risk and that import and export prices can be correlated imply that the failure to control for import price effects can bias the export price coefficients. We illustrate these points using the dataset and one of the regression specifications in a recent civil war study.

HIGHER EDUCATION IN BULGARIAN CONTEXT: PECULIARITIES AND CHALLENGES
Authors: Milenkova Valentina , Hristova Svetlana D. 
Published: May 2018

Abstract
The objective of this article is to illustrate the issues and challenges which the higher education system in Bulgaria faces, with a particular accent on the phenomenon “education per kilogram”. The latter describes, in a popular language, the up-scaling of the university graduation, related to the mass proliferation of the higher education institutions (HEIs), the facilitated access to enrolment through paid tuitions, etc. The big quantity of HEIs in the country is in a mismatch with the low percentage of GDP which the government dedicates to education. The number of HEIs is also disproportionate against its population size - 54 HEIs in Bulgaria for population of 7.2 million. The research methodology includes a desktop study based on national statistical data and data from the governmentally-supported university rating system. An empirical survey, conducted among 250 tertiary education students enrolled in four Bulgarian universities, is a valuable contribution towards disclosing the pros and cons of the teaching practices in the tertiary education in the country. The first chapter describes at large the “education per kilogram” issue with regard to its possible origins, variations and consequences for the misbalance of labour market demand for certain qualifications and the universities supplies of qualified individuals. The second chapter reveals a comparative analysis by professional fields possible through the Ministry of Education and Science’s university rating system, i.e. students’ preferences for disciplines, universities and professions; the graduates’ professional fulfilment and how the income of the recent diploma-holders is a function of attending a particular HEI. The third chapter presents a sociological survey conducted among students in four Bulgarian universities which demonstrates learners’ attitudes towards various aspects of training, teaching methods and involvement in research assignments in the context of tertiary education.
The main conclusion of the article is that the “universities per kilogram” trend brought about other corresponding characteristics, such as “students per kilogram”, “academic titles per kilogram”, etc. Hence, the large number of HEIs in Bulgaria has not led to improving the quality and efficiency of education, and yet does not respond adequately to the changing labour market demands for qualified professionals.
THE POST-MODERN AS NEO-MEDIEVAL: INTERSECTIONS OF RELIGION, NATIONALISM, AND EMPIRE IN MODERNITY AND BEYOND (WITH AN EXCURSUS ON ALBANIAN NATIONALISM)
Authors: Demjaha Dritëro 
Published: May 2018

AbstractThis essay connects Benedict Anderson’s analysis of print capitalism as the enabling feature of modernity for the emergence of nationalism with an account of pre-modern sacral imaginings. It argues, following Bronislaw Szerszynski, that the contemporary post-modern ordering of the sacred vis-à-vis nature and culture designates a ‘partial-return’ to pre-modern imaginings and a reterritorialisation of religions which engenders emerging multiplicities and co-existing differences. It argues furthermore that the nation state (and its corollaries), an institution of modernity cannot adequately respond to the antagonisms generated by the post-modern ordering of human communities and their identities. However, though this new ordering may be conceived, following Robert Bellah, as neo-archaic, it may also be conceived as neo-medieval. Accordingly, this essay proposes that the most congenial configuration to the post-modern ordering is the neo-medieval model of fuzzy borders and overlapping jurisdiction, particularly as it pertains to Albanian national identity and EU integration as a post-secular alternative to secular national-determination on the one hand, and neo-Ottomanist theocracy on the other.

Abstract
Rodríguez-Rosell, D, Yáñez-García, JM, Torres-Torrelo, J, Mora-Custodio, R, Marques, MC, and González-Badillo, JJ. Effort index as a novel variable for monitoring the level of effort during resistance exercises. J Strength Cond Res 32(8): 2139–2153, 2018—This study aimed to analyze the acute mechanical and metabolic response to resistance exercise protocols (REPs) defined by 2 variables: the first repetition's mean velocity and the percentage of velocity loss (%VL) over the set. The product of these 2 variables was termed the effort index (EI) and was used as an indicator of the degree of fatigue induced during each REP. Twenty-one resistance-trained men (11 in full squat [SQ] and 10 in bench press [BP]) performed 16 REPs separated by 72 hours. Relative loads used (50, 60, 70, and 80% 1-repetition maximum) were determined from the load-velocity relationship for the SQ and BP, whereas volume was objectively determined using the %VL attained over the set (10, 20, 30, and 45% for SQ, and 15, 25, 40, and 55% for BP). Lactate concentration and velocity against the load that elicited a ∼1.00 m·s−1 (V1 m·s−1 load) were measured before and after each REP. Post-exercise velocity with the V1 m·s−1 load and lactate concentration were significantly different (P < 0.01–0.001) from pre-exercise after all REPs. A very close relationship was found between the proposed EI and %VL with the V1 m·s−1 load (r = 0.92–0.98) and post-exercise lactate concentration (r = 0.91–0.95) in both exercises. The correlations between this new index and fatigue indicators such as VL allow us to gain further insight into the actual degree of effort incurred during resistance exercise. In addition to being a valuable addition for training monitoring, the proposed EI could also be used as an independent variable in training studies by equalizing the effort between different interventions.

Published: May 2018

Objective: The present study was designed to evaluate the relationship between gender and coexisting anxiety in patients undergoing coronary artery surgery. Materials and Methods: A total of 137 patients (41 women and 96 men with a mean age 66.1 ± 6.0 years) patients underwent state and trait anxiety evaluation at baseline (preoperatively) and at six months after (postoperatively) coronary artery bypass graft (CABG). Anxiety symptoms were assessed at enrollment using the Spielberger State-Trait Anxiety Inventory (STAI). Psychological, social, clinical, and surgical data were assessed statistically. Results: There were statistically significant differences between female and male patient characteristics for the mean age, mean education year, and mean body mass index. The women were found to be statistically younger and less educated, and more likely to be overweight, diabetic, and hyperlipidemic. The mean hospitalization time, wound infection, and extreme postoperative pain complaints were found to be higher in the female group. 61 patients (33 female and 28 male) (44.5%) were classified as presenting clinically significant anxiety symptoms (STAI score of ≥ 40). The female patients’ STAI scores were significantly higher than men in state and trait anxiety, both preoperatively and six months postoperatively. Postoperatively, there was not any significant decrease in the level of trait anxiety when comparing the level of state anxiety in female patients. Conclusion: Even after adjusting for known risk factors for compromised STAI, women do not show the same long-term quality benefits of CABG surgery that men do. The results indicate that the STAI is a valuable instrument for identifying and supporting patients with higher levels of anxiety, which can aid in determining patients that may have poor adjustment after CABG surgery.
Histidine-Tryptophan-Ketoglutarate Solution versus Blood Cardioplegia in Cardiac Surgery: A Propensity-Score Matched Analysis
Authors: Pizano Alejandro , Montes Felix Ramon , Carreño Marisol , Echeverri Dario , Umaña Juan Pablo 
Published: May 2018

Background: Choosing a cardioplegic solution is a significant issue in modern cardiac surgery. Although different options are available, the optimal strategy for myocardial protection has not been established. The aim of this study was to compare intraoperative and postoperative effects of histidine–tryptophan–ketoglutarate (HTK) solution with those of standard blood cardioplegia with St Thomas No 2 solution. The study was conducted using a large cohort of adult patients undergoing complex cardiac surgery.Methods: This study was a single center retrospective review of prospectively collected data. Between January 2008 and December 2015, 4480 patients underwent cardiac surgery using cardiopulmonary bypass (CPB) and cardioplegic arrest. Patients were divided into a blood cardioplegia group (n = 3852) and an HTK solution group (n = 628). Propensity score matching was used to adjust for differences between the two groups, and 292 matched pairs were identified. The primary end point was Intensive Care Unit (ICU) length of stay (LOS). Secondary end points included intraoperative changes in serum sodium concentration, readmission to ICU, transfusion of blood products, 30-day hospital readmission, 30-day mortality, and the incidence of major postoperative complications. Results: No significant differences were found between the matched groups with regard to baseline characteristics. Aortic cross-clamp and CPB times were longer for the blood cardioplegia (147.4 versus 132.8 min; P < .001). Administration of HTK solution was associated with acute and transient hyponatremia (141 versus 130 mmol/L; P < .001). ICU LOS was comparable between the groups (5.4 versus 5.4 days; P = .585). No significant differences were noted in any other secondary end point.Conclusions: During complex cardiac surgery, both cardioplegia techniques were equivalent in terms of early clinical outcomes.

Published: May 2018

Background: Whether coronary artery bypass grafting (CABG) should be performed on- or off-pump remains a matter of debate. We aim to present our experience with off-pump CABG. Early clinical outcome and adverse events were analyzed over the time course of the study. Methods: A total of 4310 patients undergoing isolated off- pump CABG from January 2002 until December 2016 at the Malabar Institute of Medical Sciences in India were included. Preoperative, intraoperative, and postoperative, as well as follow-up data were prospectively collected. To analyze the differences of patient characteristics and outcomes over time, five-year periods were created (early: 2002-2006; middle: 2007-2011; late: 2012-2016). Traditional techniques of quality control monitoring were applied. Results: The mean age of our patients was 59 ± 9 years, and 13% (533) were female. Postoperative mortality was observed in 0.7% (25), acute renal failure and stroke in 0.2% (8) each, and mediastinitis in 1.2% (53) of the patients. Despite the progressive worsening of the patient risk profile, significant improvement in mortality was observed over time, while stroke, acute renal failure, and mediastinitis remained similar. Continuous quality control monitoring revealed that the system was within the control boundaries for the entire period of the study. The current probability of 30-day mortality or conversion to on-pump CABG is about 0.5%. Conclusion: Off-pump CABG is safe and effective for patients undergoing CABG. It can provide superior results compared to on-pump CABG, particularly when performed by a dedicated off-pump surgeon.
Assessment of an Organ-Specific de Novo Transcriptome of the Nematode Trap-Crop, Solanum sisymbriifolium

Published: May 2018

Abstract
Solanum sisymbriifolium, also known as “Litchi Tomato” or “Sticky Nightshade,” is an undomesticated and poorly researched plant related to potato and tomato. Unlike the latter species, S. sisymbriifolium induces eggs of the cyst nematode, Globodera pallida, to hatch and migrate into its roots, but then arrests further nematode maturation. In order to provide researchers with a partial blueprint of its genetic make-up so that the mechanism of this response might be identified, we used single molecule real time (SMRT) sequencing to compile a high quality de novo transcriptome of 41,189 unigenes drawn from individually sequenced bud, root, stem, and leaf RNA populations. Functional annotation and BUSCO analysis showed that this transcriptome was surprisingly complete, even though it represented genes expressed at a single time point. By sequencing the 4 organ libraries separately, we found we could get a reliable snapshot of transcript distributions in each organ. A divergent site analysis of the merged transcriptome indicated that this species might have undergone a recent genome duplication and re-diploidization. Further analysis indicated that the plant then retained a disproportionate number of genes associated with photosynthesis and amino acid metabolism in comparison to genes with characteristics of R-proteins or involved in secondary metabolism. The former processes may have given S. sisymbriifolium a bigger competitive advantage than the latter did.

Abstract: Owing to clinical trials and improvement over the past few decades, the majority of children with acute lymphoblastic leukemia (ALL) survive by first-line chemotherapy and combat with the problems of returning to community. However, many patients may have severe acute or late therapeutic side effects, and the survival rate in some groups (e.g., patients with MLL rearrangements, hypodiploidy, IKZF1 mutation or early precursor T cell phenotype) is far behind the average. Innovative strategies in medical attendance provide better clinical outcomes for them: complete gene diagnostics, molecularly targeted anticancer treatment, immuno-oncology and immune cell therapy. The number of genes with identified alterations in leukemic lymphoblasts is over thirty and their pathobiologic role is only partly clear. There are known patient groups where the use of specific drugs is based on gene expression profiling (e.g., tyrosine kinase inhibitors in Philadelphia-like B-cell ALL). The continuous assessment of minimal residual disease became a routine due to the determination of a leukemia-associated immunophenotype by flow cytometry or a sensitive molecular marker by molecular genetics at diagnosis. Epitopes of cluster differentiation antigens on blast surface (primarily CD19, CD20 and CD22 on malignant B cells) can be attacked by monoclonal antibodies. Moreover, antitumor immunity can be strengthened utilizing either cell surface markers (bispecific T cell engagers, chimeric antigen receptor T cell therapy) or tumor-specific immune cells (immune checkpoint inhibitors). This review gives an insight into current knowledge in these innovative therapeutic directions. Orv Hetil. 2018; 159(20): 786–797.

Abstract: Introduction: Data proves that Hungary has a leading role in the statistics of oral cancer and patients living with type 2 diabetes. Aim: Our aim was to understand the statistical correlation between oral cancer and metabolic disorder (diabetes mellitus and impaired fasting glucose) due to the valuable data from the Semmelweis University. Method: We analyzed the data of 835 patients diagnosed with malignant oral cancer and 587 tumor-free control patients. We investigated the incidence and location of oral cancer among patients living with diabetes, and compared these datasets with our previous data from 14 years earlier. Results: We found that in oral cancer patients, 26.1% had diabetes and 20.8% had impaired fasting glucose; in the control group these ratios were 10.8% and 11.1%. This difference is significant (p<0.05). 14 years ago in the tumor group 14.6%, in the control group 5.6% had diabetes, while 9.7% and 5.5% had impaired fasting glucose. Lip cancer had the biggest incidence. Conclusions: The rise of type 2 diabetes in the tumor group was significant. This could be a burden for the health care system. We want to highlight the importance of interdisciplinary cooperation between health care professionals. Orv Hetil. 2018; 159(20): 803–807.

Abstract: Ten years have passed since the publication of the DEWS Report that summarized the information based on scientific literature concerning dry eye disease. Hundreds of papers have been published since then and time has come for a new summary. Organized by the Tear Film & Ocular Surface Society, 12 working groups summerized former and recent data. The DEWS II Report was created. The authors of the present publication summarize the most important changes in definition, classification, diagnostics, and therapy concerning dry eye disease. They also disclose the relevant changes on which the non-ophthalmologist specialists have to be informed. The DEWS II Report published by TFOS consists of 11 chapters. Completely new chapters deal with the role of sensation/pain and iatrogenic dry eyes. Orv Hetil. 2018; 159(20): 775–785.
Stroke-prevenció időskorban: az edoxabán hatékonysága és biztonságossága idős betegekben az ENGAGE AF vizsgálat eredményei alapján
Authors: Márk László 
Published: May 2018

Abstract: Atrial fibrillation is the most common clinically relevant arrhythmia frequently causing systemic thromboembolic events. Traditionally vitamin K antagonists had been used for decades to prevent these events. The emerging of the new direct anticoagulants has revolutionized this treatment and a gradual growth and extensive spread of usage is expected. The latest one approved in Hungary, edoxaban, is a factor Xa inhibitor. Once-daily administration and favourable safety profile are major benefits of this drug. In a large clinical study with a high number of patients it proved to be at least as effective as warfarin in the prevention of stroke and systemic embolization while causing significantly less major bleedings. As the incidence of atrial fibrillation increases with age, the observation that, compared with the other direct oral anticoagulants, the administration of edoxaban in the elderly has a favourable net clinical benefit (in the rate of prevented thromboembolic events and the number of caused bleedings) may have a great importance.
