The effect of Agricultural Landscape Type on Field Margin Flora in South Eastern Poland
Authors: Wrzesień Małgorzata , Denisow Bożena 
Published: June 2016

Abstract
Plant species diversity is threatened in many agricultural landscapes due to the changes it has to undergo. Although the modification of the agricultural landscape pattern is observed across Europe, both extensive and intensive agricultural landscapes still co-exist in Poland. The objective of the study was to examine the flora in field margins in intensively and extensively managed agricultural landscapes, located across three regions in SE Poland. The flora was compared with respect to species richness, diversity, and evenness indices. Detrended correspondence analysis was employed to characterise variation in species composition. Agricultural landscape type made a higher contribution than the topography or geology to species richness and composition in field margins. Field margins function as important habitats for general vascular plant species diversity and are useful for the conservation of rare, threatened, endangered or bee plants. A significant decline in species diversity was observed over a distance of 1000 m from the habitat elements. Plants growing on field margins are mainly perennials; however participation of annuals clearly increases in intensive landscapes. The participation of wind-dispersed species decreased in an open-spaced intensive landscape. Animal-dispersed plants predominated in an extensive landscape with forest islands. Irrespective of landscape type, native species predominated. However, these habitats create the biota and corridors for alien-invasive species as well.

Abstract
The diversity of early spring vascular flora was studied in the Sub-Pannonic steppic grassland in the village of Bilje, north eastern Croatia. In all, 109 plant taxa within 35 families were found. The highest number of taxa belongs to the families Poaceae, Fabaceae, Asteraceae, Caryophyllaceae, Lamiaceae and Rosaceae. Specific habitat conditions, characterized by moderately wet and moderately acidic soil with intermediate fertility and the effects of the continental climate favour the development of different plant life forms. Out of the total recorded plant taxa, hemicryptophytes make up 59.6%, followed by therophytes (22.0%) and geophytes (13.8%). Chorological analysis shows that the most numerous are plants of Eurasian (33.9%), Pontic-Central-Asian (21.1%) and Central European (21.1%) floral elements. According to their status in the Red List, three critically endangered (CR), one vulnerable (VU) and three nearly threatened (NT) plant species were found. Altogether, the steppe-like grassland in Bilje is a unique habitat rich in valuable plants of the Croatian flora, including the critically endangered Doronicum hungaricum, therefore it is of great importance to preserve it. Important management tools include mowing and controlling the spreading of cultivated and invasive plant species.

Authors: Janke W. , Walczak M. 
Published: June 2016

Abstract
Small-signal input characteristics of BUCK and BOOST DC-DC power converters in continuous conduction and discontinuous conduction mode have been presented. Special attention is paid to characteristics in discontinuous conduction mode. The input characteristics are derived from the general form of averaged models of converters. The frequency dependence of input admittance and other input characteristics has been observed in a relatively low-frequency range. The analytical formulas derived in the paper are illustrated by numerical calculations and verified by experiments with a laboratory model of BOOST converter. A satisfying level of conformity of calculations and measurements has been obtained.
On analog comparators for CMOS digital pixel applications. A comparative study
Authors: Jendernalik W. 
Published: June 2016

Abstract
Voltage comparator is the only - apart from the light-to-voltage converter - analog component in the digital CMOS pixel. In this work, the influence of the analog comparator nonidealities on the performance of the digital pixel has been investigated. In particular, two versions of the digital pixel have been designed in 0.35 μm CMOS technology, each using a different type of analog comparator. The properties of both versions have been compared. The first pixel utilizes a differential comparator with the increased size and improved electrical performance. The second structure is based on a very simple non-differential comparator with a reduced size and degraded performance. Theoretical analysis of the comparator nonideality effect on the quality of the image obtained from the digital pixel matrix as well as simulation results are provided.

Published: June 2016

Abstract
Chronic heart failure is a syndrome consisting in clinical symptoms that arise as a result of complications of many disease entities. According to the definition it is a condition in which, as a consequence of permanent heart dysfunction, cardiac output is reduced in relation to tissues’ metabolic demand. This results in subjective symptoms or proper cardiac output is sustained over higher filling pressure of the left heart ventricle. The occurrence of disease among adults in Europe and North America is 0.4-2%. Heart dysfunction detected by echocardiography appears with the frequency of 3%, and in people over 60 years of age it doubles with each decade of life, reaching 10% after 80 years of age. The aim of the study is to make an acquisition of fremitus in apex beat place and quantitative evaluation of some of their features which are correlated with the advanced syndrome. We have built the apparatus for the heart signal recording and proposed the original method of its analysis based on the theory of chaos and recurrence plots. It gave us, on the group of 85 patients, sensitivity equal to 0.896 specificity equal to 0.676 and the accuracy of diagnostics of the chronic heart failure equal up to 80%.
Joint compression and encryption of visual data using orthogonal parametric transforms
Authors: Puchala D. , Yatsymirskyy M. M. 
Published: June 2016

Abstract
In this paper, we introduce a novel method of joint compression and encryption of visual data. In the proposed approach the compression stage is based on block quantization while the encryption uses fast parametric orthogonal transforms of arbitrary forms in combination with a novel scheme of intra-block mixing of data vectors. Theoretical analysis of the method indicates no impact of encryption stage on the effectiveness of block quantization with an additional step of first order entropy coding. Moreover, a series of experimental studies involving natural images and JPEG lossy compression standard were performed. Here, the obtained results indicate a high level of visual content concealment with only a small reduction of compression performance. An additional analysis of security allows to state that the proposed method is resistant to cryptanalytic attacks known for visual data encryption schemes including the most efficient NZCA attack. The proposed method can be also characterized by high computational efficiency and feasibility of hardware realizations.

Authors: Nadeem S. , Sadaf H. 
Published: June 2016

Abstract
The main objective of this article is to present a mathematical model for peristaltic transport in an inclined annulus. In this analysis, two-dimensional flow of a viscous nanofluid is observed in an inclined annulus with variable viscosity. Copper as nanoparticle with blood as its base fluid has been considered. The inner tube is unifom or rigid, while the outer tube takes a sinusoidal wave. Governing equations are solved under the well-known assumptions of low Reynolds number and long-wavelength. Exact solutions have been established for both velocity and nanoparticle temperature. The features of the peristaltic motion are explored by plotting graphs and discussed in detail

Published: June 2016

Abstract
The proliferation of online digital libraries offers users a great opportunity to search their desired literatures on Web. Cross-library search applications can help users search more literature information from multiple digital libraries. Duplicate literatures detection is always a necessary step when merging the search results from multiple digital libraries due to heterogeneity and autonomy of digital libraries. To this end, this paper proposes a holistic solution which includes achieving automatic training set, holistic attribute mapping, and weight of attribute training. The experiments on real digital libraries show that the proposed solution is highly effective.
Investigation of material characteristics and processing conditions effects on bubble growth behavior in a physical foaming process
Authors: Fasihi Mohammad , Asgari Targhi Ali 
Published: June 2016

AbstractBubble growth during polymeric foam production by a physical nucleating agent is a result of rapid gas phase separation in a polymer/gas solution media. The dynamics of bubble growth is thought to be influenced by the material properties and processing conditions. However, the degree of effectiveness of each parameter has not been evaluated in earlier studies. In this work, a simplified single bubble growth in a polymeric media was modeled to specify the critical parameters affecting the bubble growth phenomenon. The predicted bubble growth profile was compared with some experimental data reported in the literature. The model was able to predict the observed bubble growth profile with acceptable precision. Therefore, it was applied to investigate the effect of each physical property of the polymer, i.e. viscosity, surface tension and diffusion coefficient as well as processing conditions, i.e. temperature and pressure release rate on the bubble growth profile. Furthermore, the impact of each factor was clarified.

Optimization of the electrochemical pre-concentration of trivalent lanthanum from aqueous media
Authors: Doyle Jamie L. , Clark Sue B. 
Published: June 2016

Abstract
Electrochemical pre-concentration has been shown to effectively increase sample sensitivity and decrease processing time; however, the basic mechanism and optimal conditions of the technique remain unknown, specifically for lanthanides. To gain a better understanding of the mechanism of action, the aqueous solution conditions required to maximize the electrochemical pre-concentration of lanthanum (La) were studied. Parameters investigated included pH, applied potential, and ionic strength. To further optimize and elucidate the mechanism of lanthanide pre-concentration, specific interactions of lanthanum with the mercury film electrode were studied. Three possible mechanisms were proposed based on preliminary observations, including ligand bridging, hydroxide formation, and amalgamation.

AbstractA GGGGCC hexanucleotide repeat expansion in the C9orf72 gene is the most common genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia (C9ALS/FTD). C9orf72 encodes two C9orf72 protein isoforms of unclear function. Reduced levels of C9orf72 expression have been reported in C9ALS/FTD patients, and although C9orf72 haploinsufficiency has been proposed to contribute to C9ALS/FTD, its significance is not yet clear. Here, we report that C9orf72 interacts with Rab1a and the Unc‐51‐like kinase 1 (ULK1) autophagy initiation complex. As a Rab1a effector, C9orf72 controls initiation of autophagy by regulating the Rab1a‐dependent trafficking of the ULK1 autophagy initiation complex to the phagophore. Accordingly, reduction of C9orf72 expression in cell lines and primary neurons attenuated autophagy and caused accumulation of p62‐positive puncta reminiscent of the p62 pathology observed in C9ALS/FTD patients. Finally, basal levels of autophagy were markedly reduced in C9ALS/FTD patient‐derived iNeurons. Thus, our data identify C9orf72 as a novel Rab1a effector in the regulation of autophagy and indicate that C9orf72 haploinsufficiency and associated reductions in autophagy might be the underlying cause of C9ALS/FTD‐associated p62 pathology.
Telomere Dysfunction Triggers Palindrome Formation Independently of Double-Strand Break Repair Mechanisms
Authors: Raykov Vasil , Marvin Marcus E , Louis Edward J , Maringele Laura 
Published: June 2016

Abstract
Inverted chromosome duplications or palindromes are linked with genetic disorders and malignant transformation. They are considered by-products of DNA double-strand break (DSB) repair: the homologous recombination (HR) and the nonhomologous end joining (NHEJ). Palindromes near chromosome ends are often triggered by telomere losses. An important question is to what extent their formation depends upon DSB repair mechanisms. Here we addressed this question using yeast genetics and comparative genomic hybridization. We induced palindrome formation by passaging cells lacking any form of telomere maintenance (telomerase and telomere recombination). Surprisingly, we found that DNA ligase 4, essential for NHEJ, did not make a significant contribution to palindrome formation induced by telomere losses. Moreover RAD51, important for certain HR-derived mechanisms, had little effect. Furthermore RAD52, which is essential for HR in yeast, appeared to decrease the number of palindromes in cells proliferating without telomeres. This study also uncovered an important role for Rev3 and Rev7 (but not for Pol32) subunits of polymerase ζ in the survival of cells undergoing telomere losses and forming palindromes. We propose a model called short-inverted repeat-induced synthesis in which DNA synthesis, rather than DSB repair, drives the inverted duplication triggered by telomere dysfunction.
Mutation Is a Sufficient and Robust Predictor of Genetic Variation for Mitotic Spindle Traits in Caenorhabditis elegans
Authors: Farhadifar Reza , Ponciano José Miguel , Andersen Erik C , Needleman Daniel J , Baer Charles F 
Published: June 2016

Abstract
Different types of phenotypic traits consistently exhibit different levels of genetic variation in natural populations. There are two potential explanations: Either mutation produces genetic variation at different rates or natural selection removes or promotes genetic variation at different rates. Whether mutation or selection is of greater general importance is a longstanding unresolved question in evolutionary genetics. We report mutational variances (VM) for 19 traits related to the first mitotic cell division in Caenorhabditis elegans and compare them to the standing genetic variances (VG) for the same suite of traits in a worldwide collection C. elegans. Two robust conclusions emerge. First, the mutational process is highly repeatable: The correlation between VM in two independent sets of mutation accumulation lines is ∼0.9. Second, VM for a trait is a good predictor of VG for that trait: The correlation between VM and VG is ∼0.9. This result is predicted for a population at mutation–selection balance; it is not predicted if balancing selection plays a primary role in maintaining genetic variation.

Abstract: Handling criminal acts of terrorism by the government can be divided into two areas, within Correctional Institution and outside prisons. Legal approach based on Law No. 15 of 2003 on Combating Criminal Acts of Terrorism has not been optimally reduce the potential for violence of terrorism, since countermeasures tend to only show the use of weapons only. Successful handling of terrorism characterized by inmates terrorism cooperation with the government to inform the network of terrorism. Bina Damai development is applied to terrorists can reduce resistance and revenge, for promoting the process of dialogue rather than armed military action. Peaceful approach influenced legal and cultural communication strategy with the clarity of program coordination of the parties that have the authority handling criminal acts of terrorism. Abstrak: Penanganan tindak pidana terorisme yang dilakukan pemerintah dapat dibedakan atas dua bidang, di dalam Lembaga Pemasyarakatan dan di luar Lembaga pemasyarakatan. Pendekatan hukum yang berdasarkan UU Nomor 15 tahun 2003 tentang Pemberantasan Tindak Pidana Terorisme belum secara optimal mengurangi potensi kekerasan atas tindak terorisme karena cenderung mempertontonkan penggunaan senjata. Beberapa keberhasilan penanganan tindak pidana terorisme ditandai adanya kerjasama narapidana terorisme dengan pemerintah untuk memberi informasi jaringan terorisme sekaligus pengakuan terhadap Negara Kesatuan Republik Indonesia (NKRI) berdasarkan Pancasila. Pengembangan bina damai yang diterapkan pada teroris dapat menggurangi perlawanan dan balas dendam karena mengedepankan proses dialog daripada aksi militer bersenjata. Bina damai merupakan transisi dari proses rekonsiliasi menuju tahap konsolidasi untuk terbangunnya perdamaian yang permanen. Pendekatan damai dipengaruhi strategi komunikasi hukum dan budaya disertai kejelasan program koordinasi dari pihak-pihak yang memiliki kewenangan penanganan tindak pidana terorisme.

It is happen because regulary about dispute resolution mechanism to determination of the political parties participating in the election not certain. So, necesary legal certainty especially the regulation about the election law dispute resolution and must be clearly divided authority and responsibilities of each election institute bodies. Abstrak: Dalam rangka meningkatkan kualitas penyelenggaraan pemilu dibutuhkan lembaga penyelenggara pemilu yang profesional. Namun, hal tersebut sulit diwujudkan apabila terus terjadi perbedaan pendapat antar lembaga penyelenggara pemilu itu sendiriyaitu antara Komisi Pemilihan Umum (KPU), Badan Pengawas Pemilu (Bawaslu) dan Dewan Kehormatan Penyelenggara Pemilu (DKPP). Hal tersebut disebabkan karena adanya ketidakjelasan pengaturan mengenai mekanisme penyelesaian sengketa pemilu dalam penetapan partai Pemilu, khususnya mengenai alur penyelesaian sengketa penetapan partai politik. Karenanya pengaturannya harus diperbaiki dan secara tegas diperjelas tentang wewenang dan tanggungjawab masing-masing lembaga penyelenggara pemilu. DOI: 10.15408/jch.v4i1.3198
