The Vegetation of Isoëto-Nano-Juncetea Class in the Sluch River Valley (Ukraine)
Authors: Korotka Inna , Pashkevych Nataliia 
Published: October 2018

Abstract
Vegetation of Isoëto-Nano-Juncetea class has been investigated in the Sluch River valley within the forest-steppe zone. We distinguished three associations belonging to Verbenion supinae (Pulicario vulgaris-Menthetum pulegii Slavnić 1951), Eleocharition ovatae (Cyperetum micheliani Horvatić 1931 and Veronico anagalloidis-Lythretum hyssopifoliae Wagner ex Holzner 1973) alliances. The floristic composition of these syntaxa, is rich in diagnostic species of Bidentetea tripartitae and Phragmito-Magnocaricetea classes, which could indicate a transition to more sustainable communities in the succession row. Our current work is a small portion of a large task to clarify the location of ‘hot spots’ across the overall diversity of Isoëto-Nano-Juncetea, and to identify where and how this diversity can be maintained best.
New distribution data for Alburnus sava Bogutskaya, Zupančič, Jelić, Diripasko & Naseka, 2017 and Telestes souffia (Risso, 1827) in the Western Balkans
Authors: Vucić Matej , Sučić Ivana , Jelić Dušan 
Published: October 2018

Abstract
The distribution data of Alburnus sava and Telestes souffia has been updated in Croatia in comparison to the previously known data. Alburnus sava is much more widespread in the Sava drainage and also occurs in the River Sava near the town of Županja, rivers Drina and Bosna. Telestes souffia has a much more restricted range in Croatia than previously believed and is only known from the Bregana, small, right tributary of the River Sava on the Croatian-Slovenian border. Both species are poorly known and threatened.
The relationship between condition and form factors of the Adriatic fishes in the Zadar area
Authors: Treer Tomislav , Babačić Helena 
Published: October 2018

Abstract
The relationship between the mean Fulton’s condition and form factors of 12 marine species (N=209 fish specimens) caught in the Zadar area (middle eastern Adriatic) was analysed. The lowest mean condition factor (K = 0.6329) referred to the elongated Trachinus draco, while the highest one (K = 1.7758) referred to the deep-bodied Scorpaena porcus. The correlation between the mean Fulton’s condition and form factors of these 12 populations was highly significant (K = 0.404 + 0.663 a3.0; r2 = 0.815; P < 0.01). Including more species in the calculation would give even more accurate results.
From extra- to intratextual characteristics: Charting the space of variation in Czech through MDA

Published: October 2018

AbstractThis paper is part of a larger research effort on language variability aimed at uncovering the relations between extra- and intratextual characteristics of Czech texts by means of multi-dimensional analysis. The palpable lack of prior art on quantitative register analysis of Czech led to several distinctive methodological decisions, concerning namely corpus design, feature selection and the parameters of factor analysis, especially the number of dimensions to extract. We report on these for their potential relevance to other researchers embarking on a similar journey. In order to demonstrate the viability of the model, we also present a brief interpretation of the resulting dimensions.
Turing Patterns and Biological Explanation
Authors: Serban Maria 
Published: October 2018

AbstractTuring patterns are a class of minimal mathematical models that have been used to discover and conceptualize certain abstract features of early biological development. This paper examines a range of these minimal models in order to articulate and elaborate a philosophical analysis of their epistemic uses. It is argued that minimal mathematical models aid in structuring the epistemic practices of biology by providing precise descriptions of the quantitative relations between various features of the complex systems, generating novel predictions that can be compared with experimental data, promoting theory exploration, and acting as constitutive parts of empirically adequate explanations of naturally occurring phenomena, such as biological pattern formation. Focusing on the roles that minimal model explanations play in science motivates the adoption of a broader diachronic view of scientific explanation.
A certain family of subgroups of ℤ𝑛⋆ is weakly pseudo-free under the general integer factoring intractability assumption
Authors: Anokhin Mikhail 
Published: October 2018

AbstractLet {\mathbb{G}_{n}} be the subgroup of elements of odd order in the group {\mathbb{Z}^{\star}_{n}}, and let {\mathcal{U}(\mathbb{G}_{n})} be the uniform probability distribution on {\mathbb{G}_{n}}.
In this paper, we establish a probabilistic polynomial-time reduction from finding a nontrivial divisor of a composite number n to finding a nontrivial relation between l elements chosen independently and uniformly at random from {\mathbb{G}_{n}}, where {l\geq 1} is given in unary as a part of the input.
Assume that finding a nontrivial divisor of a random number in some set N of composite numbers (for a given security parameter) is a computationally hard problem.
Then, using the above-mentioned reduction, we prove that the family {((\mathbb{G}_{n},\mathcal{U}(\mathbb{G}_{n}))\mid n\in N)} of computational abelian groups is weakly pseudo-free.
The disadvantage of this result is that the probability ensemble {(\mathcal{U}(\mathbb{G}_{n})\mid n\in N)} is not polynomial-time samplable.
To overcome this disadvantage, we construct a polynomial-time computable function {\nu\colon D\to N} (where {D\subseteq\{0,1\}^{*}}) and a polynomial-time samplable probability ensemble {(\mathcal{G}_{d}\mid d\in D)} (where {\mathcal{G}_{d}} is a distribution on {\mathbb{G}_{\nu(d)}} for each {d\in D}) such that the family {((\mathbb{G}_{\nu(d)},\mathcal{G}_{d})\mid d\in D)} of computational abelian groups is weakly pseudo-free.
Oxidative stress and antioxidants in the pathophysiology of malignant melanoma
Authors: Obrador Elena , Liu-Smith Feng , Dellinger Ryan W. , Salvador Rosario , Meyskens Frank L. , Estrela José M. 
Published: October 2018

Abstract
The high number of somatic mutations in the melanoma genome associated with cumulative ultra violet (UV) exposure has rendered it one of the most difficult of cancers to treat. With new treatment approaches based on targeted and immune therapies, drug resistance has appeared as a consistent problem. Redox biology, including reactive oxygen and nitrogen species (ROS and RNS), plays a central role in all aspects of melanoma pathophysiology, from initiation to progression and to metastatic cells. The involvement of melanin production and UV radiation in ROS/RNS generation has rendered the melanocytic lineage a unique system for studying redox biology. Overall, an elevated oxidative status has been associated with melanoma, thus much effort has been expended to prevent or treat melanoma using antioxidants which are expected to counteract oxidative stress. The consequence of this redox-rebalance seems to be two-fold: on the one hand, cells may behave less aggressively or even undergo apoptosis; on the other hand, cells may survive better after being disseminated into the circulating system or after drug treatment, thus resulting in metastasis promotion or further drug resistance. In this review we summarize the current understanding of redox signaling in melanoma at cellular and systemic levels and discuss the experimental and potential clinic use of antioxidants and new epigenetic redox modifiers.
The associations between sleep duration and sleep quality with self-rated health in young adults: a population-based study
Authors: Štefan Lovro , Sporiš Goran , Krističević Tomislav 
Published: October 2018

Abstract

Background
The main purpose of the present study was to explore significant associations between sleep duration and sleep quality with poor self-rated health.

Methods
Subjects were 2100 university students (49.6% of women), aged 18–24 years. The associations between sleep duration and sleep quality with self-rated health were examined by using structured questionnaires.

Results
After adjusting for sex, body mass index (BMI), socio-economic status, smoking status, alcohol consumption, presence or absence of chronic diseases, psychological distress and physical activity, very short [<6 h, odds ratio (OR) = 4.78; 95% confidence interval (CI) 1.95–11.76] and very long (>10 h, OR = 4.09; 95% CI 2.26–7.39) sleep duration and poor sleep quality (OR = 1.44; 95% CI 1.01–2.05) were associated with poor self-rated health.

Conclusions
Our results show both dependent and independent associations between sleep duration and sleep quality with self-rated health in a large sample of young adults. Thus, policies that promote adequate sleep duration and good sleep quality are warranted.
Unpreparedness, impurity and paradoxical feeling: menstruation narratives of Iranian women
Authors: Seyed Hosseini Afsaneh Sadat 
Published: October 2018

Abstract

Background
Menstruation is universally experienced by all healthy females from menarche to menopause, although the cognitive and emotional dimension of this experience may differ across time and place.

Objective
This qualitative study was conducted to explore the menstruation experiences of Iranian women.

Methods
Eight Iranian university students, aged between 21 and 25 years, who were resident in Tehran, were interviewed and data were analyzed using an interpretive phenomenological analysis approach.

Results
Two main themes of the participant narratives were identified: “The menarche” and “women’s perception of menstruation”. Each of these elements comprised a number of sub-themes. The menarche experience was related to “inadequate preparation”, “fear and horror” and “the mother”. Women perceived menstruation as “shameful and secret”, “sickness and impurity”, “bothersome and painful”, accompanied with “paradoxical feelings” and “irregularity and unpredictability”.

Discussion
The results of this study revealed that menarche experience for most of the women was a negative experience. Feelings of being fearful, shocked or worried could be influenced by inadequate preparation for menstruation. They reveived insufficient information from school or their friends and their mothers, specifically. Menstruation is shameful, kept secret and is usually hidden from men. Most of them experienced menstruation as a sickness and considered menstruating women as impure who must obey religious rules. Some of them had symptoms of premenstrual syndrome. For some women menstruation was both painful and pleasing and its irregularity and unpredictability made women anxious. The findings of this study highlight the effect of sociocultural factors on the menstruation experience.

Published: October 2018

Abstract

Introduction
Almost all the bone mass in females is accumulated during adolescence and especially in the years immediately following menstruation. Self-efficacy plays an important role in moderating the relationship between knowledge and behavior. This study aimed to determine the self-efficacy of osteoporosis preventive behaviors and its predictors in female high school students.

Methodology
This descriptive-analytical cross-sectional study was conducted on 330 female high school students in Saveh, Iran during 2016–2017. A two-stage cluster sampling method was used to select the participants. Data were collected using a socio-demographic questionnaire, the Osteoporosis Knowledge Test (OKT) and the Osteoporosis Self-Efficacy Scale (OSES). A general linear model was used to determine the self-efficacy predictors of osteoporosis preventive behaviors.

Results
The mean [standard deviation (SD)] of the total OKT score was 11.08 (4.08) of attainable range from 0 to 32. The mean (SD) of the total OSES score was 121.97 (37.36) of attainable range from 0 to 200. The mean (SD) of the exercise and calcium subscales of OSES were 58.39 (22.56) and 63.57 (21.02), respectively. There were significant relationships between the total OKT score with the total OSES score (r = 0.16, p = 0.003) and its subscales, including exercise (r = 0.16, p = 0.002) and calcium (r = 0.11, p = 0.03) scores. According to the adjusted general linear model, the variables of economic status, educational level and osteoporosis knowledge were predictors of the self-efficacy in the studied students.

Conclusion
Findings suggested that most of the students had moderate levels of knowledge and self-efficacy regarding osteoporosis preventive behaviors; therefore, improving the knowledge and self-efficacy of this group can play a significant role in promoting their health.

Published: October 2018

Abstract
The water splitting reaction using aluminum represents one of the best methods for on-demand hydrogen requirements. The present paper describes the hydrogen generation in water splitting reaction using aluminum in presence of potassium hydroxide as an alkaline activator. The effect of concentration of KOH, temperature, and shape of aluminum particles on the hydrogen generation in water splitting reaction was experimentally studied using various concentrations of aqueous KOH viz. 0.25 N, 0.50 N, 0.75 N and 1.0 N, at different temperatures of 30 °C, 40 °C, and 50 °C for Al powder (diameter: 200 mesh) and Al foil (thickness: 11 microns). The complete conversion of Al was recorded for all the experimental runs. The average hydrogen generation rate was found to vary between 3.40 ml/min to 21 ml/min per 0.1 g aluminum under considered concentrations and temperatures. The shrinking core model was applied to the experimental data for predicting the rate controlling mechanism.

Published: October 2018

Abstract
The effects of drying temperature by continuous and intermittent drying on the drying characteristics of soybean were determined in this study. Among the thin-layer drying models, the Midilli–Kucuk model showed the best fit (R
2 > 0.99) to describe the drying of soybean. At 300 min of the effective drying time, the moisture content of continuous drying at 35, 40, and 45 ºC were 9.38 (±0.00), 8.69 (±0.17), and 7.70 % (±0.48), respectively; while the moisture content of intermittent drying at 35, 40, and 45 ºC were 8.28 (±0.21), 7.31 (±0.41), and 6.97 % (±0.07), respectively. The image analysis method for detection of the crack in soybean demonstrated that at the target moisture content (7.7 %), cracked grain ratios with intermittent drying at 35, 40, and 45 ºC were reduced by 52.08, 27.59, and 18.24 %, respectively. With the effective drying time, the activation energy for intermittent drying (9.33 kJ/mol) was significantly lower than that value for continuous drying (21.23 kJ/mol).

is outputted of the classical Jacobi polynomial (see Definition 2.3). Also, we list and derive some facts related to the shifted fractional-order Jacobi orthogonal function. Spectral collocation techniques are addressed to solve the multidimensional distributed-order diffusion equations (MDODEs). A mixed of shifted Jacobi polynomials and shifted fractional order Jacobi orthogonal functions are used as basis functions to adapt the spatial and temporal discretizations, respectively. Based on the selected basis, a spectral collocation method is listed to approximate the MDODEs. By means of the selected basis functions, the given conditions are automatically satisfied. We conclude with the application of spectral collocation method for multi-dimensional distributed-order diffusion equations.

Authors: Rshikesan P. B. , Subramanya Pailoor , Nidhi Ram 
Published: October 2018

Abstract

Background
Globally obesity increase is a big challenge. Obesity causes many non-communicable diseases. Options to control obesity are in search.

Aim: To assess the outcome of 3 months follow-up period, after 14 weeks yoga intervention, for body composition and sleep quality parameters on obese male in urban setting.

Materials and methods
Design: Parallel group RCT (randomized controlled trial) on obese male. The two groups were yoga and control groups, with yoga (n = 37, age 40.03 ± 8.74), control (n = 35, age 42.20 ± 12.06). The IAYT (integrated approach of yoga therapy) training was given to yoga group for 14 weeks, and the unsupervised yoga practice was continued by the subjects at their home, for further 3 months. Training was 1.5 hour daily for 5 days in a week, which included the IAYT module of Suryanamaskara Asana Pranayama and relaxation. No yoga activity but walking etc. for the same time, was given to control group. Body composition parameters were assessed through BIA (bioelectrical impedance) method using InBody R 20 model. The sleep quality was assessed using PSQI (Pittsburgh sleep quality index). Within group and between group analysis were performed, using SPSS version 21. The correlation analysis was carried out on the difference in pre follow-up values.

Results
During the follow-up period within the group, the body composition parameters improved and the parameters of quality of sleep showed trends of improvement. Also some of the gain obtained during 14 weeks intervention was lost during follow-up period.

Conclusions
The changes observed may indicate the long-term benefits of yoga practice for control of obesity in urban setting for males.
Arrayed Waveguide Grating and Re-Circulating Buffer Based Optical Packet Switch
Authors: Shukla Manahar Prashant , Srivastava Rajiv 
Published: October 2018

Abstract
Optical packet switching has gained popularity in past decade. However, due to technical challenges all- optical switching is not implemented till date, still hybrid switching where both optical and electrical switching are used simultaneously by-passing the limitations of both the technologies. In fiber delay lines (FDLs) buffering is limited due to accumulated losses and noises, and most of the times short term storage is enough in optical switching, but in case of long term storage, re-circulating type buffer can be used, but again due to accumulation of degrading terms re-circulation count is limited therefore in case of longer duration storage, electronic buffer is better choice. In this paper, we have proposed a hybrid buffer based optical switch where both optical and electronic buffers are used for storage of contending packets, and optical buffer is re-circulating in nature. The performance of the switch is measured in terms of bit error rate (BER) and packet loss probability, and BER performance is compared with recently proposed design, and it has been found that the proposed switch is comparatively much superior to earlier one.
Multi-verb constructions in Malto
Authors: Puttaswamy Chaithra 
Published: October 2018

AbstractThis paper discusses the classification of verbal constructions in Malto based on functions expressed through the co-occurrence of verb words at various levels within clauses. Multi-verb constructions in Malto are discussed within the framework of the theories of juncture and nexus proposed by Van Valin, Robert D, and Randy J LaPolla. 1997.Syntax: Structure, Meaning and Function. Cambridge: Cambridge University Press. The functional classes of multi-verb constructions in Malto discussed in this paper include explicator compound verbs, conjunctive participle constructions, and reduplicated verbs. Rank-defining properties where the inflectional properties relate to the concept of finiteness in verbs are compared with rank shift in Malto. This includes several possibilities such as two clauses coalescing into a single core, category change where nominals are derived from verbs by attaching a nominaliser, or verbs functioning as adverbials by virtue of their position relative to a finite verb.
An inventory of Medieval Greek Apocalyptic Sources (c. 500 – 1500 AD): Naming and dating, editions and manuscripts
Authors: Kraft András 
Published: October 2018

AbstractThis bibliographical inventory surveys 50 medieval Greek apocalyptic sources ranging from the turn of the sixth century until the late fifteenth century. The surveyed material consists of historical and moral apocalypses, oracular prophecies and end-time calculations. The survey enumerates the various appellations and dating attempts for each text as proposed in modern scholarship. Moreover, references to editions and translations of each source are provided; they are followed by a preliminary list of the known manuscript witnesses. The purpose of the inventory is twofold: (i) it presents a quantitative estimation of the respective manuscript distribution. Altogether 1024 textual witnesses in 688 manuscripts have been identified to contain the surveyed apocalyptic texts. It has been found that about 70 % of all manuscript material dates to the fifteenth century or later. Consequently, it can be established that the period surrounding and following the halōsis of 1453 functions as a filter that, to a large extent, regulates our access to and conditions our understanding of medieval Greek apocalyptic thought. Moreover, the inventory (ii) provides a holistic yet concise overview of a large section of Byzantine apocalypticism, which appears necessary for any comprehensive research that engages in (or steps beyond) intertextual analysis.
