Abstract. Tirkaamiana MT, Partasasmita R. Kamarubayana L. 2019. Growth patterns of Shorea leprosula and Dryobalanops lanceolata in Borneo’s forest managed with Selective Cutting with Line Replanting System. Biodiversitas 20: 1160-1165. Dryobalanops lanceolata is a species of plant in the family Dipterocarpaceae, which indigenous of Borneo. It is found in at least five protected areas (Kabilli-Sepilok Forest Reserve, Danum Valley Conservation Area, Ulu Temburong, Lambir, and Gunung Mulu National Parks), but is threatened elsewhere due to habitat loss. The demand for its timber is very high, so it requires conservation efforts while at the same time maintaining its productivity to meet the timber demand. One of the efforts to increase productivity of production forest in Indonesia is implementing Selective Logging with Line Replanting System (TPTJ). In this system superior species are planted in the planting lines. This study aimed to determine the growth of Shorea leprosula and Dryobalanops lanceolata planted in different planting line widths. Data of diameter increment of S. leprosula and D. lanceolata were obtained by observing 4 permanent sample plots (PUP) at concession areas of PT Balikpapan Forest Industries in Penajam Paser Utara, East Kalimantan, Indonesia. The results showed that the average diameter increment of S. leprosula and D. lanceolata at the planting line width of 3 meters was 1.47cm/yr and 0.74 cm/yr respectively, and at the planting line width of 6 meters was 2.08 cm/yr and 1.14 cm/yr respectively. The differences in planting line width had very significant effect on the growth and diameter increment of S. leprosula, presumably due to the increase of light intensity to optimal level which accelerates stomata opening and transpiration rate, thus affecting the rate of photosynthesis.
Affective variables and informal digital learning of English: Keys to willingness to communicate in a second language
Authors: Lee Ju Seong , Drajati Nur Arifah
Published: March 2019

This study examined the under-researched relationship between informal digital learning of English (IDLE) activities (receptive IDLE activities and productive IDLE activities), affective variables (grit, motivation, self-confidence and second language speaking anxiety) and willingness to communicate in a second language. Data (N = 183) were collected through a questionnaire from one state university in an English-as-a-foreign-language Indonesian context. The results showed that students’ willingness to communicate correlated significantly with all of the IDLE activities and affective variables. However, only productive IDLE activities, grit, self-confidence, and motivation were identified as the significant predictors of students’ willingness to communicate. Findings suggest that students’ IDLE engagement and affective states play a significant role in a second language communication. In particular, pedagogical benefits of affective variables (e.g., grit, self-confidence, and motivation) and productive IDLE activities should be emphasised to facilitate students’ willingness to communicate in a second language. These results will broaden current knowledge of IDLE and second language communication behaviour, which can contribute to bridging the interdisciplinary gap between computer assisted language learning, second language acquisition, and psychology.
Interdisciplinary approach for simulation of starting points for optical and architectural design
Authors: Livshits Irina L. , Glebovskyi Alexander S. , Protsuto Marina V. , Volkova Svetlana L.
Published: March 2019

Modern science becomes more complex day after day. Besides, there appeared many unpredictable links between different subjects, which we never expected to be connected. This is called ‘interdisciplinary’ science. For example, just occasionally we found common points in the simulation of the starting input for optical and architectural design, and moreover, we discovered a lot of similar procedures in both of them. Basing on the analysis of these two fields of knowledge, as well as using optical expert and architectural expert evaluations, we propose an approach to build a heuristic algorithm for computer aided design in these two fields. Later, we expect that it grows into a set of expert systems under the roof of artificial intelligence. We see in the near future a prospective of using new technology in design–building information modeling, which could be expanded from architectural design to optical design, etc. Besides, this is our first experience in this field. We consider that it is possible to widen it further to other subjects. The main ideas of this approach are presented.
Intensity of stripping and sugar content in the bark and the bast of European beech (Fagus sylvatica)
Authors: Kurek Tomasz , Todys Jacek , Pazdrowski Witold , Szymański Marek , Łukowski Adrian
Published: March 2019

The choice of particular trees for stripping by deer is puzzling because a preference is observed for trees of the highest social class. Trees ranked highest in the stand can produce more carbohydrates as a product of carbon assimilation. Among the many important nutrient and defense groups of metabolites in plants, high sugar content is postulated to be an attractant due to its impact on the sense of taste of different herbivores. Thus, we hypothesize that the carbohydrate content in the bast of the European beech is the most important factor by which deer make their choice. Our aim was to assess whether the sugar content in the bark and in the bast can be a factor which influences the intensity of bark stripping of particular trees in a beech thicket by red deer. A single episode connected with tree damaging pertained to 7% of the trees on the analyzed sampling plots. In total, 27% of the trees were damaged, including old damages. The mean size of damage to a given tree equaled 36% of the tree’s circumference and 0.06 m2 of the trunk’s surface. Analysis of the sugar content in the bast and in the bark jointly indicates that the trees subjected to bark stripping possessed a distinctly higher sugar content than the trees which were not damaged. The probability of bark stripping grows together with an increase in the sugar content of the bark and of the bast.

The present study was conducted to evaluate the impact of monometallic and bimetallic nanoparticles (NPs) of copper (Cu) and silver (Ag) from Justicia spicigera on the photochemical efficiency and phenol pattern of Prosopis glandulosa. In this study, the existence of localized surface plasmon resonance absorption associated with the nano-sized nature of Ag, Cu and Cu/Ag particles was confirmed by the presence of a single peak around 487, 585, and 487/580 nm respectively. Zeta potential and electrophoretic mobility were found to be 0.2 mV and 0.02 μmcm/(Vs) for synthesized NPs indicating less stability and thus tendency to agglomerate, and broad distribution of particles. Cu-NPs and Cu/Ag-NPs demonstrate that the dispersed phase is stable and has a minimum particle size at zeta potentials above –30 mV. Changes in phenolic compounds, total chlorophyll, and photochemical efficiency in leaves exposed to Ag, Cu and Cu/Ag phyto-nanoparticles were evaluated up to 72 hours. The results revealed that Ag-NP and Cu-NP from J. spicigera at 100 mg/L showed significant reduction in chlorophyll, epidermal polyphenol content and photochemical efficiency of P. glandulosa. In contrast, the application of bimetallic Cu/Ag-NP from J. spicigera showed a positive impact on physiological parameters of P. glandulosa after 72 h of exposure.
Edge Patch-Wise Local Projection Stabilized Nonconforming FEM for the Oseen Problem
Authors: Biswas Rahul , Dond Asha K. , Gudi Thirupathi
Published: March 2019

In finite element approximation of the Oseen problem, one needs to handle two major difficulties, namely, the lack of stability due to convection dominance and the incompatibility between the approximating finite element spaces for the velocity and the pressure. These difficulties are addressed in this article by using an edge patch-wise local projection (EPLP) stabilization technique. The article analyses the EPLP stabilized nonconforming finite element methods for the Oseen problem. For approximating the velocity, the lowest-order Crouzeix–Raviart (CR) nonconforming finite element space is considered; whereas for approximating the pressure, two discrete spaces are considered, namely, the piecewise constant polynomial space and the lowest-order CR finite element space. The proposed discrete weak formulation is a combination of the standard Galerkin method, EPLP stabilization and weakly imposed boundary condition by using Nitsche’s technique. The resulting bilinear form satisfies an inf-sup condition with respect to EPLP norm, which leads to the well-posedness of the discrete problem. A priori error analysis assures the optimal order of convergence in both the cases, that is, order one in the case of piecewise constant approximation and

in the case of CR-finite element approximation for pressure. The numerical experiments illustrate the theoretical findings.
Social Kinds, Reference, and Meta-Ontological Revisionism
Authors: Xhignesse Michel-Antoine
Published: March 2019

Julian Dodd has characterized the default position in metaphysics as meta-ontologically realist: the answers to first-order ontological questions are thought to be entirely independent of the things we say and think about the entities at issue. Consequently, folk ontologies are liable to substantial error. But while this epistemic humility is commendable where the ontology of natural kinds is concerned, it seems misplaced with respect to social kinds since their ontology is dependent upon the human social world. Using art and art-kinds as paradigmatic examples of social kinds, I argue that meta-ontological realism sets conditions that are too strict to apply to social kinds. Nevertheless, I argue that we should not be too quick to embrace the conclusion that our folk theories of social kinds cannot err substantially. By modelling the reference of social kind-terms on that of natural kind-terms, it becomes clear that in both cases, our sole epistemic privilege lies in our ability to pinpoint the subject of our inquiries.
Bringing Fiscal Sponsor Activity to Light
Authors: Andersson Fredrik O. , Neely Daniel G.
Published: March 2019

We explore the extent to which nonprofits engaging as fiscal sponsors publicly disclose their fiscal sponsor activities. Fiscal sponsors can play an important role in the nonprofit sector by providing capacity support that is often lacking. However, the option to employ a fiscal sponsor is often not well known to smaller entities that would be in the best position to take advantage of the administrative efficiency provided by fiscal sponsors. In reviewing the publicly disclosed information of 74 fiscal sponsors we find that the majority of fiscal sponsors do not disclosure their fiscal sponsorship activity on the Form 990 nor on their website. In order to enhance the sector’s understanding of the important role fiscal sponsors play, and ensure fiscal sponsors are held accountable for their fiscal sponsorship activity, we recommend enhanced disclosures of fiscal sponsorship.

Alkoholos májbetegség: a genetikai-epigenetikai tényezők szerepe és az absztinencia hatása
Authors: Pár Alajos , Pár Gabriella
Published: March 2019

Abstract:

The pathogenesis of alcoholic liver disease depends not only on the toxic effects of alcohol, but also on the complex interaction of host’s and environmental factors. Thus, the genetic pre-disposition, co-morbidities and behavioral factors all play a role in the individual variations in the disease outcomes. On the other hand, the essential part of the therapeutic strategy is the complete withdrawal of the harmful etiological agent. The present paper is devoted to overview the genetics, the environmental factors and the effects of abstinence in alcoholic liver disease. Genetic variants in two enzymes involved in the metabolism of ethanol, alcohol-dehydrogenase ADH1B *2 and aldehyde-dehydrogenase ALDH2 *2 through increasing the blood level of acetaldehyde, may play a “protective” role against alcoholism. The P450 CYP2E1 *5 c2, an inducible microsomal oxidase, upregulated by ethanol and by formation of acetaldehyde and reactive oxygen species, increases liver toxicity. Three novel gene polymorphisms – such as the patatin-like phospholipase domain-containing 3 (PNPLA3 I148M C>G), the transmembrane 6 superfamily member 2 (TM6SF2 E167K), and the membrane-bound O-acyltransferase domain-containing 7 (MB0AT7 rs641738 C>T) – have been proven as risk factors of steatosis, fibrosis and even hepatocellular carcinoma in both alcoholic and non-alcoholic fatty liver disease patients. Alcohol-induced epigenetic effects, reversible but inheritable gene expression alterations – as histon modulations, DNA methylation and micro-RNA-s – are of importance in the pathogenesis as well, and in the future, they may serve as diagnostic markers and therapeutic targets. Women are at greater risk of developing alcoholic cirrhosis, furthermore, malnutrition, obesity, diabetes, smoking, and hepatitis virus infections are also risk factors. Alcoholic liver disease should be regarded as a preventable disease. Several clinical studies revealed that abstinence may result in the regression of steatohepatitis and fibrosis, compensation of cirrhosis, improving disease outcome and increasing survival even in patients with advanced stages. Early diagnosis and multidisciplinary interventions are highly required to achieve long-term abstinence and to prevent alcoholic cirrhosis. Orv Hetil. 2019; 160(14): 524–532.

Purpose. Analysis of electron microscopic changes in rabbit eyes with intravitreal tamponade of perfluorocarbon liquids (PFCL) (perfluoro-1,3-dimethylcyclohexane and perfluorodecalin).Material and Methods. The study was performed on Chinchilla breed rabbits. 25G vitrectomy with PFCL intravitreal tamponade was performed on 12 eyes of 6 rabbits (perfluorodecalin (Bausch+Lomb «Dk-line», USA) and perfluoro-1,3-dimethylcyclohexane (ZAO “Optimedservis”, Russia). Standard three-port vitrectomy technique was used. After removal of the vitreous body 2.5 ml of PFCL were injected in vitreous cavity. Research studies were performed in 5, 14 and 30 days after surgery by electron microscopy. Eyes were enucleated in 20 minutes after animal was killed by air embolization. Intact eyes were used as a control. All samples were prepared in same conditions. The damage of the retina architectonics and the presence of intracellular inclusions were evaluated.Results. Tamponade of the vitreous cavity by both types of PFCL in 5, 14 and 30 day caused following similar electron microscopic changes at date: swelling ganglion layer and dystrophy of inner and outer nuclear layer. Electron microscopic changes in outer nuclear layer appeared at 30 days. The photoreceptor neurons were characterized by single ultrastructural changes. Retina pigment epithelium cells had a typical ultrastructure.Conclusion. Intravitreal perfluoro-1,3-dimethylcyclohexane tamponade caused similar electron microscopic changes as well as perfluorodecalin in the experiment and it was relatively harmless to rabbit retina for up to 14 days. Irreversible changes in the retinal ultrastructure were not observed.

To verify real-time properties of UML statecharts one may apply a UPPAAL, toolbox for model checking of real-time systems. One of the most suitable ways to specify an operational semantics of UML statecharts is to invoke the formal model of Hierarchical Timed Automata. Since the model language of UPPAAL is based on Networks of Timed Automata one has to provide a conversion of Hierarchical Timed Automata to Networks of Timed Automata. In this paper we describe this conversion algorithm and prove that it is correct w.r.t. UPPAAL query language which is based on the subset of Timed CTL.
Tree Slicing in Clone Detection: Syntactic Analysis Made (Semi)-Semantic
Authors: Akhin Marat , Itsykson Vladimir
Published: March 2019

Nowadays most of software contains code duplication that leads to serious problems in software maintenance. A lot of different clone detection approaches have been proposed over the years to deal with this problem, but almost all of them do not consider semantic properties of the source code. We propose to reinforce traditional tree-based clone detection algorithms by using additional information about variable slices. This allows to find intertwined/gapped clones on variables; preliminary evaluation confirms applicability of our approach to real-world software.

Treatment of Extensive Plaque Psoriasis and Psoriatic Arthropathy using Methotrexate in a Patient with High Serum Alkaline Phosphatase
Authors: HH Suad , El Amin Muna Mohammed , Modawe Gad Allah , Elbasheer Osman
Published: March 2019

Background: Psoriasis is an autoimmune inflammatory, chronic, and relapsing disease of the skin, which can also present with severe joint inflammation and deformity. There are many treatment options, but the severe forms of psoriasis are treated successfully with cytotoxic and biologic therapies. Methotrexate being cheap and available in Sudan is considered a good option for patients with severe and extensive forms of psoriasis.One of the main drawbacks is hepatotoxicity. The aim of this report is to share an experience of treating the patient with oral methotrexate in the presence of a relative contraindication to this therapy.
Method: We present a 60-year-old female with extensive skin psoriasis and psoriatic arthropathy. Investigations showed high serum alkaline phosphatase and low serum albumen. Other liver enzymes, CBC, ultrasound abdomen were all unremarkable. Patient was admitted and a weekly dose of methotrexate was given in addition to topical preparation and supportive treatment; three months later, patient improved andwas moved to topical therapy. A check of serum alkaline phosphatase and albumen every week was done.
Results: The patient was successfully and safely treated with methotrexate. Serum alkaline phosphatase was normal within the second month treatment, and serum albumen was normal after only one month of treatment.
Conclusion: High serum alkaline phosphatase is considered a relative contraindication to the use of methotrexate, high level can be found in bone diseases. Serum albumen can be low in dermatologic diseases with excessive shedding of scales and can be corrected with protein formulas and high protein diets.
Recommendations: Methotrexate is recommended for the treatment of severe morbid forms of psoriasis. The biologic therapy for severe forms of psoriasis is now available and can be a good alternative for the treatment of severe forms of psoriasis in good centers and for patients who can afford and in patients with absolute contraindications to methotrexate therapy.
Microbiological Profile of Neonatal Sepsis at a Maternity Hospital in Omdurman, Sudan

Published: March 2019

Background: Neonatal sepsis is a clinical syndrome characterized by systemic signs of infection and accompanied by bacteremia in the first month of life. It is a major cause of morbidity and mortality in neonatal period. The study was conducted to determine microbiological profile and antibiogram of neonatal sepsis at Omdurman Maternity Hospital.
Methods: This was a cross-sectional hospital-based study involving 202 neonatal blood cultures at Omdurman Maternity Hospital during the period from April 2017 to April 2018. Specimens were cultured in Brain Heart Infusion broth followed by subculture of isolates on blood agar, MacConkey agar, and Chocolate agar and incubated aerobically at 37ºC for 24 h. The isolates were tested for their susceptibility to antimicrobial agents using the Kirby Bauer disc diffusion method.
Results: Of 202 positive blood cultures, 130 cases (64.4%) were early onset and 72 cases (35.6%) were recorded for late onset sepsis. Gram-negative pathogens approaching (123, 60.9%). Staphylococcus aureus was the most common organism in both groups of neonatal sepsis being isolated from (71, 35.7%), followed by Klebsiella pneumoniae (43, 21.2%). Gram-negative organisms were sensitive to Imepenem (97.3%) and Meropenem (80.5%) and resistant to third-generation Cephalosporins (65.3%) and Amoxicillin/Clavulanic acid (91.4%). Gram-positive organisms were resistant to Cefotaxime (75%), Amoxicillin/Clavulanic acid (65.4%), and Clindamycin (68.2%); 91.6% of gram-positive isolates were sensitive to Vancomycin.
Conclusion: Gram-negative pathogens took the major spectrum of isolates. Klebsiella pneumoniae (21.2%) was the most frequent gram-negative organism. Methicillinresistant Staphylococcus aureus (MRSA) (33.7%) was the most common isolate. Most of the isolates were multidrug resistant. The best choice for treatment is Vancomycin (8.4%) and Imepenem (2.7%) for gram-positive and gram-negative, respectively. Adherence to antibiotic policy, antimicrobial surveillance, and policy updating is necessary.
Functional properties of the Su(Hw) complex are determined by its regulatory environment and multiple interactions on the Su(Hw) protein platform

Published: March 2019

The Su(Hw) protein was first identified as a DNA-binding component of an insulator complex in Drosophila. Insulators are regulatory elements that can block the enhancer-promoter communication and exhibit boundary activity. Some insulator complexes contribute to the higher-order organization of chromatin in topologically associated domains that are fundamental elements of the eukaryotic genomic structure. The Su(Hw)-dependent protein complex is a unique model for studying the insulator, since its basic structural components affecting its activity are already known. However, the mechanisms involving this complex in various regulatory processes and the precise interaction between the components of the Su(Hw) insulators remain poorly understood. Our recent studies reveal the fine mechanism of formation and function of the Su(Hw) insulator. Our results provide, for the first time, an example of a high complexity of interactions between the insulator proteins that are required to form the (Su(Hw)/Mod(mdg4)-67.2/CP190) complex. All interactions between the proteins are to a greater or lesser extent redundant, which increases the reliability of the complex formation. We conclude that both association with CP190 and Mod(mdg4)-67.2 partners and the proper organization of the DNA binding site are essential for the efficient recruitment of the Su(Hw) complex to chromatin insulators. In this review, we demonstrate the role of multiple interactions between the major components of the Su(Hw) insulator complex (Su(Hw)/Mod(mdg4)-67.2/CP190) in its activity. It was shown that Su(Hw) may regulate the enhancer–promoter communication via the newly described insulator neutralization mechanism. Moreover, Su(Hw) participates in direct regulation of activity of vicinity promoters. Finally, we demonstrate the mechanism of organization of “insulator bodies” and suggest a model describing their role in proper binding of the Su(Hw) complex to chromatin.
