Authors: DALCI İlhan , ÖZYAPICI Hasan
Published: January 2020

This study aims to investigate how firm size
moderates the relationship between debt and accounting quality of the
non-financial firms listed on Borsa Istanbul (BIST) in Turkey. The financial
data are downloaded from Orbis including the years from 2010 to 2018. Ordinary
least squares regression has been applied. This study contributes to the
literature by investigating how firm size shapes the impact of leverage on
accounting quality. The results of this
study show that the effect of leverage on accounting quality is changing
depending on the firm size. Accordingly, this study concludes that the
magnitude and the direction of the effect of leverage on accounting quality
become stronger when the firm size gets smaller.
CENTRAL AUDIT ACTIVITIES AS A CONTINUOUS AUDIT APPROACH IN THE TURKISH BANKING SECTOR: A CASE STUDY ABOUT FRAUDS IN SAVINGS ACCOUNTS
Authors: KABAN İsmail
Published: January 2020

Developments in information technology constitute the core of a fundamental transformation of internal audit approaches. The traditional concept of internal audit on periodic and traditional auditing with the inclusion of concepts such as data mining, artificial intelligence, and machine learning is replaced by modern continuous, risk-focused auditing. Recently, in sectors that have high transaction volume such as banking, continuous audit activities combined with data mining applications have become prominent in effectively managing fraud risk. In this study, an example of the examination process related to savings account fraud in Turkey has been presented by providing basic information about the central audit activities applied as a continuous audit approach in the banking sector. The banking transactions used as data in this fraud auditing were generated realistically and at random. Data mining techniques have been applied to these transactions to detect fraud risks.

Osmanlı sefaret (elçilik) ve şehbenderlikleri (konsolosluk) bulundukları ülkelerde ve şehirlerde devleti temsilen önemli görevler üstlenmişlerdir. Devletin dış dünyadaki gözü ve kulağı olmak gibi bir misyonla faaliyet gösteren temsilciliklerin en önemli görevlerinden biri, Osmanlı meskûkâtı (madeni para) ve kâğıt parasının sahtelerini dışarıda üretip, içeride başta İstanbul olmak üzere çeşitli vilayetlerde piyasaya süren muhtelif ülke vatandaşı yabancı kalpazanlarla sorunun kaynağında mücadele etmek olmuştur. Sefaret ve şehbenderlikler görev yaptıkları ülke ve şehirlerde kalp paraların ve kalpazanların izini sürerek yakalanmalarını sağlamaktan, gerektiğinde bizzat davacı taraf olarak devleti temsilen kalpazanların yargılanma süreçlerini ve mahkemelerini takibe kadar her ne gerekiyor ise üzerlerine düşeni yaparak kalpazanlıkla mücadelede aktif bir rol üstlenmişlerdir. Kalpazanlık sorununa ilişkin resmi yazışmalara yansıyan olaylara bakıldığında, Osmanlı piyasalarında tedavüle sürülen sahte sikkelerin ve kâğıt paranın üretim ve sürümünde yabancıların rolünün son derece fazla olduğu, yabancı ülke ve şehirlerin adının sıklıkla geçtiği görülür. Dolayısıyla buralarda devletin hak ve hukukunu korumakla görevli sefaret ve şehbenderliklerin kalpazanlıkla ve kalp paralarla mücadeledeki rolü de o nispette önemli olmuştur.

Numerical Investigation of Heat Transfer and Fluid Flow Characteristics in Circular Wavy Microchannels with Sidewall Rib
Authors: Valaparla Ranjith Kumar , Balasubramanian Karthik , Kiran Kumar Kupireddy
Published: January 2020

Purpose: Numerical investigation was carried out to study the hydro-thermal characteristics in circular wavy microchannels (CWMCs) with sidewall rib. Thermal resistance and pressure drop penalty were compared with sinusoidal wavy microchannels (SWMCs) design. Parametric study on sidewall rib was also carried to minimize the pressure drop penalty and to achieve lower thermal resistance. Introducing sidewall rib in the CWMCs leads to the formation of more Deans vortices. This leads to an effective fluid mixing and augments the convective heat transfer. Design methodology/approach: A computational solid domain was created in SOLIDWORKS and the fluid domain was produced by circular arc profile for the entire length of heat sink. 3-D numerical investigation was carried out using ANSYS FLUENT software. Created computational domain was imported into ANSYS WORKBENCH. Meshing was executed in ANSYS mesh module. The computational domains were meshed using hexahedral elements adopting match control on both sides of microchannel (MC). The numerical investigation was carried out in the Re range from 100 to 300 with constant heat flux (50 W/cm2) applied at the bottom of the channel. Heat transfer and fluid flow characteristics were explained with velocity vectors, velocity contours and temperature contours. Findings: From numerical studies, it is concluded that CWMC with sidewall rib width (0.15 mm) leads to 33.6 % lower thermal resistance than SWMC with pressure drop penalty. Originality/Value: Present study is useful to identify the optimum deign to augment the heat dissipation performance of microchannel heat sink.
Numerical Evaluation of Liquid Mixing in a Serpentine Square Convergent-divergent Passive Micromixer

Published: January 2020

Micromixers are crucial components to carry out chemical, biomedical and bio-chemical analyses on µTAS (micro total analysis system) or Lab-on-chips. Simple planar type passive mixers are always most desirable over three dimensional or complex geometries of passive mixers or active mixers as they are less expensive, easy to fabricate, and easy to integrate into complex miniaturized systems. However, at very low Reynolds numbers (0 to 100), due to the inherent laminar nature of the microfluidic flows, mixing remains challenging in passive mixers. Previous studies reported that serpentine square-wave micromixer is one of the simple and effective passive device for micromixing. In the present study, to further enhance the mixing efficiency of the device, horizontal straight portions of serpentine square wave mixer are replaced with convergent-divergent passages and the mixing performance of both mixers are evaluated in the Re range of 0 to 100. It is observed in the low Re (0 to 10), mixing in the square wave mixer with convergent-divergent portions (SQW-CD mixer) is governed completely by pure diffusion as in the case of square wave mixer with straight horizontal portions (SQW mixer). However, at high Re (Re > 10), the presence of convergent-divergent portions in the SQW-CD mixer considerably intensify the stretching and folding of samples in the mixing channel. Additionally, the extra recess available at the bends of SQW-CD mixer creates recirculation zones in the mixer. Therefore, a significant improvement in the mixing performance is achieved at high Re (Re > 10) for SQW-CD mixer as compared to conventional SQW mixer. This would allow shorter mixing lengths for SQW-CD mixer as compared to Sq wave mixer. However, with increase in Re, the rise in pressure drop is considerably high for SQW-CD mixer as compared to SQW mixer.

Published: January 2020

In this paper, fractional order PID controller, as well as integer order PID controller, is designed for non-linear system to enhance the system’s performance and gain the stability. The novelty of the work is achieved by the development of a new methodology for integer order PID and fractional order PID control tuning by optimizing the parameters of controllers using the Genetic Algorithms optimization technique. The performance of any system mainly depends upon how efficiently the controller will be working and hence that’s how most crucial part of the designing of FOPID controller or any controller is the tuning of its parameters. The uniquely designed and tuned parameters of the FOPID controller which is obtained by optimizing all the five parameters by using an evolutionary algorithm optimization technique i. e. a genetic algorithm which is a very powerful search tool and carrying heuristic characteristics. This method of tuning the FOPID controller which is designed and has been applied over the conical tank (nonlinear) system. The most important step in applying genetic algorithm is the selection of the fitness function and hence Integral of time multiplied by absolute error (ITAE) have been used here as the fitness function. Each chromosome comprised of all the five parameters of FOPID controller, which have been further optimised using above mentioned fitness function. From the simulation results, it can be observed that the solutions which are obtained optimally, presents an excellent performance for the system studied, by improving the behaviour of the system satisfactorily. Simulation results also show that the proposed FOPID controller gives improved performance over classical PID controller in terms of IAE and TV.
Benthic Diatoms as Valuable Indicators of Anthropogenic Eutrophication in Biomonitoring of Ribbon Lake
Authors: Messyasz Beata , Treska Ewa
Published: January 2020

In Europe the monitoring of lakes with regard to benthic diatoms is still conducted in line with the European Water Framework Directive. Ribbon lakes are a special case as extremely steep slopes of the lake basin cause their littoral zone to be narrow. The Durowskie ribbon lake was chosen as a model for the assessment of the ecological status of waters based on its Diatom Index. Given its use in recreation, it is under heavy anthropogenic pressure. Physicochemical and biological parameters were monitored in the peak of the vegetational season (July, August) between 2010 and 2018 at 12 varied littoral sites across the full length of the shoreline. This long-term analysis of the Diatom Index, despite showing an improvement in the quality of water, demonstrated the ecological state of Lake Durowskie to be weak (southern, deep part) to moderate (north, shallow part). The taxonomic structure of diatoms (referral and indicator taxa) in phytobenthos communities allowed to show the changes in physicochemical parameters of the environment such as pH, oxygen dissolved in water and its trophic status. Research results are shown in relation to the anthropogenic changes to the lake’s direct catchment area and the results of the physicochemical monitoring of waters.

Authors: Korzeniowska Joanna , Panek Ewa
Published: January 2020

The aim of this study is to test two plant species, the common dandelion Taraxacum officinale and moss Pleurozium schreberi, as bio monitors of trace metal pollution emitted by motor vehicles. The samples of the moss Pleurozium schreberi (green segments) and the common dandelion Taraxacum officinale (leaves) were collected within 12 transects along the state road No. E77 near Chyzne, Sothern Poland. The transects were located on the eastern and western side of the road (downwind and upwind towards prevailing winds), at the following distances from the road: 5, 50, 100, 300 500 and 600 m. Total concentrations of Cr, Cu, Ni, Pb, Sb and Zn in the plant material were determined. The studied species accumulated trace metals in the similar amounts. Statistically significant differences in metal concentrations between two plant species were observed only in the case of Cu and Pb. Copper concentrations were higher in the common dandelion, while the moss Pleurozium schreberi accumulated considerably higher amounts of Pb. There is a statistically significant negative correlation between the trace metal concentrations in plants and the distance to the road. There are also statistically significant differences in concentrations of Cr, Cu, Ni, Pb and Zn in the common dandelion between the samples collected from the opposite sides of the road: upwind/downwind towards the prevailing wind direction at the distance up to 300 meters. The concentrations are higher on the downwind side of the road.

Authors: Oz Nurtac , Topal Bayram , Uzun Halil Ibrahim
Published: January 2020

The Riva River is a water basin located within the borders of Istanbul in the Marmara Region (Turkey) in the south-north direction. Water samples were taken for the 35 km drainage area of the Riva River Basin before the river flows into the Black Sea at 4 stations on the Riva River every month and analyses were carried out. Changes were observed in the quality of water from upstream to downstream. For this purpose, the spatial and temporal variations of water quality were investigated using 13 water quality variables with the ANOVA test. It was observed that COD, DO, S and BOD were important in determining the spatial variation. On the other hand, it was found out that all the variables were effective in determining the temporal variation. Moreover, the correlation analysis which was carried out in order to assess the relations between water quality variables showed that the variables of BOD-COD, BOD-EC, COD-EC, BOD-T and COD-T were correlated and the regression analysis showed that COD, TKN and NH4-N explained BOD and BOD, NH4-N, T and TSS explained COD by approximately 80 %. Consequently, the Artificial Neural Network (ANN), Decision Tree and Logistic Regression models were developed using the data of training set in order to predict the water quality classes of the variables of COD, BOD and NH4-N. Quality classes were predicted for the variables by inputting the data of testing set into the developed models. According to these results, it was seen that the ANN was the best prediction model for COD, the Decision Tree for BOD and the ANN and Decision Tree for NH4-N.

Authors: Tokarčíková Michaela , Seidlerová Jana , Motyka Oldřich , Šafaříková Mirka
Published: January 2020

Biochar produced from fermentation residue of maize hybrid was used in untreated form as a sorbent for the removal of Cd(II), Pb(II) and Zn(II) from aqueous solution. The capability of biochar to immobilized ions was investigated by leaching test. Equilibrium between biochar sample and studied elements in solution was reached at a contact time 30 min for Zn(II) and 90 min for Pb(II) and Cd(II). The experimental data were described by pseudofirst-order and pseudo-second-order kinetic model, two- and three-parameter isotherms in non-linear form. The maximum sorption capacity achieved was 30.07 mg·g−1 in the case of Cd(II) ions, 99.44 mg·g−1 in the case of Pb(II) and 40.18 in the case of Zn(II). Biochar developed for this study is comparable to conventional biochar, low cost, non-toxic and experimental results show that is a suitable and efficient sorbent for Cd(II), Pb(II) and Zn(II) removal from aqueous solutions.

Authors: Quek Check Shyong , Ngadi Norzita , Zaini Muhammad Abbas Ahmad
Published: January 2020

This work was aimed at evaluating the sorption of dispersed oil by kapok fiber. The physicochemical characteristics of kapok fiber were investigated using BET, SEM, FTIR, XRD, contact angle and elemental analysis. The oil droplet size distribution at different temperatures was analysed using a Coulter counter, and its relationship with sorption was investigated. The effects of dosage, hydraulic retention time and temperature, on the sorption performance were studied. The result indicates that the sorption of dispersed oil by kapok fiber is spontaneous, endothermic and agreed with the pseudo-first-order reaction kinetics. The amount of oil that could be removed is about 28.5 %, while that of water is less than 1 % of the original amount (0.5 dm3). Kapok is a promising natural hydrophobic fiber for dispersed oil removal from oily wastewater.

Authors: Szutt Adriana , Dołhańczuk-Śródka Agnieszka , Sporek Monika
Published: January 2020

Plants have been used for their aromatic and medicinal purposes for centuries. The genus Pelargonium contains about 250-280 species and cultivated around the world for the production of essential oils and absolutes. Pelargonium species are remarkable for their odour diversity, from fresh, lemon and minty scent, through floral, rose, fruity up to spicy and camphoreous smell as well as many health beneficial properties, that is why their essential oils are widely used in perfume, cosmetic, food and pharmaceutical industries. The aim of this study was to determine variability in populations of Pelargonium genus by evaluating their differences in quantitative and qualitative essential oils compositions. This study determined that of all the examined essential oil, the one of P. graveolens indoor cultivar has the closest C:G ratio (1.16) which makes it a very valuable product. In comparison with available literature, beside the geographical region of plant growth, all essential oils from P. graveolens contain a diverse range of compounds, nevertheless, in every single one, geraniol and citronellol are present in the most significant fraction of the total oil. The examined P. roseum essential oil was characterized by the highest level of citronellol (44.62 % of total oil), but it can be due to the chemical reactions (conversion geraniol into citronellol) occurring in stored product.

Authors: Ghauri Aymen Owais , Ahmad Saeed , Rehman Tayyeba
Published: January 2020

Background

Diabetes is the one of the leading cause of morbidity and mortality. Traditionally phytotherapy is widely being used for diabetes treatment and highly valued. Citrus colocynthis has known anti-diabetic potential. However, anti-diabetic potential of hydro-ethanolic extract of C. colocynthis pulpy flesh with seeds is not reported yet.

Methods

The extract of C. colocynthis pulpy flesh with seeds was done by maceration method using 70% ethanol. To evaluate anti-diabetic and antioxidant potential of the seeded fruit in vitro, α-glucosidase and DPPH inhibition assays was done, respectively. In vivo study used streptozotocin (STZ) induced diabetes model of rats. Rats were randomized in five groups i. e. normal control, negative control, standard control, C. colocynthis 150 and 300 mg/kg. STZ was administered to all groups except normal control. After wards, plant extract and glibenclamide is continued for 14 days. Blood samples were collected from rat tail vein daily and from Cardiac puncture at the end of study. The blood glucose levels were monitored daily by using one-touch blood glucose monitoring system. The blood glucose level was monitored on 0, 1st, 5th, 8th, 11th, and 14th day of induction.

Results

Hydro-ethanolic extract of C. colocynthis pulpy flesh with seeds was able to decolorize DPPH and therefore possess antioxidant potential, continuous administration for 14 days showed a marked decrease in serum glucose levels (p 0.01) it is found to be somewhat less effective as glibenclamide (standard control) (p 0.001). A time-dependent decrease in blood glucose levels was observed (351.3 ± 4 to 258 m/kg).

Conclusion

Hydro-ethanolic extract of C. colocynthis pulpy flesh with seeds lowered the serum triglyceride and cholesterol levels in diabetic rats significantly as compared to negative control. The hypoglycemic effect of hydro-ethanolic extract of C. colocynthis pulpy flesh with seeds is may be due to α-glucosidase inhibition potential.

La protección penal del agua como recurso natural. Una valoración crítica de las diferencias entre España y Portugal
Authors: Rodríguez Vázquez Virxilio
Published: January 2020

Éste es un estudio de Derecho comparado sobre la protección penal del agua en España y Portugal para reflejar las diferencias entre ambos países, valorar las posibles repercusiones prácticas de aquéllas y hacer propuestas para una homogenización normativa. Para llevar a cabo este estudio se utiliza el método dogmático, propio de las Ciencias penales, que parte del Derecho positivo contenido en el Código Penal español (CPe) y portugués (CPp) entendido como un «dogma», postulados establecidos por el legislador, para analizarlos siguiendo la teoría del delito, comprobando su coherencia interna y con el propio sistema jurídicopenal. A continuación, se comparan las conductas penalmente relevantes contempladas en uno y otro texto, los resultados exigidos para calificar aquéllas como delitos, así como los sujetos penalmente responsables, y sus penas. Las consideraciones finales tratan de poner de manifiesto las relevantes diferencias existentes entre el CPe y el CPp en materia de protección del agua.
La eficacia eximente de los programas de prevención de delitos
Authors: González Cussac José Luis
Published: January 2020

El art. 31 bis Código Penal español atribuye eficacia eximente o atenuante de la responsabilidad penal de la persona jurídica a los programas de prevención de delitos. Pero esta eficacia no es automática, sino que requiere la concurrencia de una serie de condiciones. Así, si el delito de referencia fue cometido por un representante, administrador o directivo, se precisa, conforme al art. 31 bis 2, el cumplimiento de cuatro condiciones. Por el contrario, si el delito de referencia fue cometido por un subordinado, solo se exige explícitamente una condición de acuerdo al art. 31 bis 4. Por su parte, las sociedades de pequeñas dimensiones presentan un régimen parcialmente singular en esta materia.Por último, advertir que no deben confundirse las condiciones requeridas legalmente para eximir o atenuar, con los requisitos de los programas descritos en el art. 31 bis 5.
Ser y deber ser de la comunicación de las mujeres reclusas en las prisiones de Sinaloa, México: una propuesta socioeducativa.
Authors: Coronel Cabanillas Ana Imelda , Gastélum Escalante Jorge Antonio
Published: January 2020

El presente artículo tiene como objetivo conocer las necesidades y obstáculos que las mujeres presas en Sinaloa enfrentan para comunicarse al interior y al exterior del reclusorio. El enfoque metódico es mixto o qualimétrico. En lo cuantitativo se aplicó una encuesta de 37 ítems agrupados en siete dimensiones de la vida personal, familiar, legal, de salud, seguridad, educativa y laboral de las reclusas. En lo cualitativo se les entrevistó a fin de conocer sus necesidades comunicativas con su familia, amigos, abogado, autoridad penitenciaria y visita conyugal, así como los medios usados para comunicarse.Los procesos comunicativos no se completan; son visibles los déficits al respecto, lo que contradice el deber ser teórico y jurídico referente: más del 50% de ellas no reciben visita de sus familiares, cónyuges o novios, y quienes son frecuentadas por sus parejas no disponen de áreas exclusivas para el caso; asimismo, menos del 10 % son visitadas por sus amistades. Sin embargo, las mujeres reclusas minimizan esta carencia afectiva comunicándose con su familia a través de sus teléfonos celulares que poseen de manera clandestina, ya que las casetas telefónicas  de los reclusorios no pueden usarlas porque generalmente están descompuestas. En general conocen sus derechos y la obligación estatal de proporcionarles abogado defensor, sin embargo, su representante de oficio no les informa ni atiende ni en tiempo ni en forma y con las autoridades penitenciarias no establecen ningún tipo de comunicación. En razón de la problemática de comunicación de estas mujeres, se propone humanizar las cárceles para mujeres de Sinaloa.

Published: January 2020

Com a passagem de uma cidade moderna para contemporânea, novas questões e desafios surgiram, na qual mudanças de ordem tecnológica desorganizaram e reorganizaram o território e, para compreender as consequências causadas nas cidades e no seu funcionamento é necessário que seja feita uma leitura sociocultural. Estudos têm demonstrado a importância das relações dialógicas entre a arquitetura do lugar e as reais necessidades socioeconômicas e culturais dos usuários. A Agenda2030 da ONU propõe a melhoria da vida das pessoas em todos os lugares para garantir uma vida com dignidade, na qual um de seus objetivos visa tornar as cidades e os assentamentos humanos inclusivos, seguros, resilientes e sustentáveis. Este estudo pretende oferecer novos parâmetros para o desenvolvimento de um olhar que tornará possível a existência de, a partir de uma análise social e cultural, um espaço público inclusivo como uma nova maneira de olhar a cidade.

Published: January 2020

From August 2017 to September 2018, IOM (International Organization for Migration) experimented for the first time, participatory video methodology integrated in the activities of its Global Migration Film Festival (GMFF). The main purpose was to innovate and enable communities in the frontlines of displacement and different humanitarian action settings into creating through film their own narratives with their own hands and style. Their videos would then integrate the film festival that traditionally curates professionally produced movies. Amongst the six countries and areas with displaced population reached by the project is Roraima, Brazil, that has been hosting thousands of Venezuelans that crossed the Brazilian border fleeing from degrading living conditions. In May 2018 the authors spent a week at Pintolândia Indigenous Shelter located in the capital Boa Vista, facilitating displaced Venezuelans of the ethical groups of Warao and Eñepas make their own films to be screened locally and around the world. Furthermore, the facilitators would observe the potential benefits of the method to generate some level of social cohesion and integration between the participating displaced communities that came from different regions of Venezuela.

Published: January 2020

Na trajetória de Marshall McLuhan, conceitos fundamentais como “os meios como extensõesdo homem” e “o meio é a mensagem” representam muito mais do que uma revolução. Sãosínteses e rupturas. Traço de uma revolução tecnológica travada naquele contexto, meados doséculo XX. As últimas conferências e entrevistas de McLuhan revelam outra face muitoimportante do pensador, verdadeiros diagnósticos das dificuldades de se lidar com umuniverso como o do autor. Ressalta-se, acima de tudo, sua sensibilidade vanguardista, aplicadaaos Media com desdobramentos ainda em processos de sistematização. Suas ideias tinham acapacidade de atualizar e também de absorver as contínuas, constantes e fluidas mudanças. Asúltimas conferências e entrevistas estão repletas de manifestações subjetivas e de ironias sutisque esboçam uma teoria original. Este artigo busca delinear as condições em que surgiram osprimeiros argumentos da construção dos conceitos principais para que deles se possa extrair o essencial como processo condutor e catalisador de suas teorias sobre imediatos da tecnologia sobre o sistema nervoso central.
The Unique Antimicrobial Recognition and Signaling Pathways in Tardigrades with a Comparison Across Ecdysozoa

Published: January 2020

Tardigrades are microscopic animals known to withstand unfavorable abiotic conditions. These animals are also constantly exposed to biotic stresses, including parasites and internal microbiomes. However, the tardigrade immune mechanisms against these biotic stresses are largely uncharacterized. Due to the contentious phylogenetic position of tardigrades, it is not intuitive whether they possess an immune system more similar to that of arthropods (e.g., Toll, Imd, and JNK pathways of the Drosophila melanogaster antimicrobial response) or to that of nematodes (e.g., the Tir-1/Nsy-1/Sek-1/Pmk-1/Atf-7 signaling cassette [called Tir-1 pathway here]) in Caenorhabditis elegans). In this study, comparative genomic analyses were conducted to mine homologs of canonical D. melanogaster and C. elegans immune pathway genes from eight tardigrades (Echiniscoides cf. sigismundi, Echiniscus testudo, Hypsibius exemplaris, Mesobiotus philippinicus, Milnesium tardigradum, Paramacrobiotus richtersi, Richtersius cf. coronifer, and Ramazzottius varieornatus) and four non-arthropod ecdysozoans (two onychophorans: Epiperipatus sp. and Opisthopatus kwazululandi; one nematomorph: Paragordius varius; and one priapulan: Priapulus caudatus) in order to provide insights into the tardigrade antimicrobial system. No homologs of the intracellular components of the Toll pathway were detected in any of the tardigrades examined. Likewise, no homologs of most of the Imd pathway genes were detected in any of the tardigrades or any of the other non-arthropod ecdysozoans. Both the JNK and Tir-1 pathways, on the other hand, were found to be conserved across ecdysozoans. Interestingly, tardigrades had no detectable homologs of NF-κB, the major activator of antimicrobial response gene expression. Instead, tardigrades appear to possess NF-κB distantly related NFAT homologs. Overall, our results show that tardigrades have a unique gene pathway repertoire that differs from that of other ecdysozoans. Our study also provides a framework for future studies on tardigrade immune responses.
Chromosome-Level Assembly of Drosophila bifasciata Reveals Important Karyotypic Transition of the X Chromosome

Published: January 2020

The Drosophila obscura species group is one of the most studied clades of Drosophila and harbors multiple distinct karyotypes. Here we present a de novo genome assembly and annotation of D. bifasciata, a species which represents an important subgroup for which no high-quality chromosome-level genome assembly currently exists. We combined long-read sequencing (Nanopore) and Hi-C scaffolding to achieve a highly contiguous genome assembly approximately 193 Mb in size, with repetitive elements constituting 30.1% of the total length. Drosophila bifasciata harbors four large metacentric chromosomes and the small dot, and our assembly contains each chromosome in a single scaffold, including the highly repetitive pericentromeres, which were largely composed of Jockey and Gypsy transposable elements. We annotated a total of 12,821 protein-coding genes and comparisons of synteny with D. athabasca orthologs show that the large metacentric pericentromeric regions of multiple chromosomes are conserved between these species. Importantly, Muller A (X chromosome) was found to be metacentric in D. bifasciata and the pericentromeric region appears homologous to the pericentromeric region of the fused Muller A-AD (XL and XR) of pseudoobscura/affinis subgroup species. Our finding suggests a metacentric ancestral X fused to a telocentric Muller D and created the large neo-X (Muller A-AD) chromosome ∼15 MYA. We also confirm the fusion of Muller C and D in D. bifasciata and show that it likely involved a centromere-centromere fusion.

Published: January 2020

Background and aims. To compare pain levels experienced during initial alignment with three different orthodontic appliance types and to correlate pain with male and female differences, if any.

Methods. A prospective, randomized 3- arm parallel trial allocated 36 adult orthodontic patients into three appliance groups: MBT 0.022” slot (Mini Twin, Ormco, Glendora, USA), self ligating 0.022" slot Damon 3MX (Ormco, Glendora, USA) and clear aligners (Smile align, Mumbai, India). The level of discomfort was assessed through a questionnaire based on the visual analogue scale at four hours, twenty four hours, third and seventh day after appliance placement.

Results. Patients treated with clear aligners reported less pain than patients treated with conventional and self ligating fixed appliances. Patients treated with MBT conventional appliances showed greater pain levels than Damon appliances. A significantly higher visual analogue scale score was observed at 24 hours and the least visual analogue scale scores on the seventh day post appliance placement.

Conclusion. During the first week of orthodontic treatment, patients treated with clear aligners reported lower pain than those treated with conventional and self-ligating appliances.
Admissibility of the Use of Electronic Means of Evidence Obtained Unlawfully in a Civil Proceeding
Authors: Klich Aleksandra
Published: January 2020

The admissibility of the use of evidence obtained unlawfully, referred to as the fruit of the poisonous tree, still remains an unresolved issue on the basis of Polish procedural law. The author in her paper will focus on such forms of evidence, which are more and more often the subject of evidentiary procedures, noting that this mainly concerns the content of private conversations conducted with the use of messengers and community portals, call recordings, and telephone billings, data obtained from mobile phones, or so-called print screens, which are often obtained in an illegal manner, interfering with the sphere of privacy of the other person.
The Relevance of Consumer Behavior and Competition of Products to Levying Excise Duties on Cosmetics under EU Law
Authors: Mickutė Karolina
Published: January 2020

In Bene Factum, the Court of Justice of the European Union ruled that cosmetic products should be exempt from excise duty on alcoholic beverages if they contain ethyl alcohol regardless the actual use of the product (consumer behavior). In order to assess the prerequisites for the proper application of EU law in the field of excise duty, the article assesses the mechanism of determining product competition at the EU and International Trade Law levels, which is important for the classification of products for tax purposes, including the extent to which cosmetic products compete with alcoholic beverages, how private business is limited by consumer habits, and possible governmental intervention in this context.

REGIMENTAL PRISON IN HETMANATE: APPEARANCE AND CONDITION OF BUILDING IN THE MIDDLE OF THE XVIII CENTURY
Authors: Sapronov Andrii
Published: January 2020

The article attempts to investigate a condition of the buildings for the prisoners and guardians in the middle of the XVIII century in the regimental prisons of the Hetmanate and in Hlukhiv. The prison was an essential public building in the early modern towns. The excellent condition of the walls of the jail was a guarantee of successful punishment for the thieves and the prevention of new offences.In the legal sources (in the Statutes of Lithuania and in the Laws by Which the Little Russian People Are Judged), there are three types of places where prisoners could be held – the “lower” and “upper” prisons and a separate room for convicted prisoners. The appearance of prisons in domestic historiography is poorly researched and untold. The studies indicate that various types of buildings were used as a prison, such as a hut, a shed. However, sometimes researchers mentioned the prisons with a binary structure (upper and lower).Typically, in criminal proceedings, the appearance of prisons was not reported. If the court session ended successfully, that is the punishment of the thief, then the description of the prison in the document was unnecessary. Therefore, the author used the materials, which illustrated the cases of escapes from the prisons. In addition to them, the researcher used the documents of the regimental offices, in which they requested permission from the capital authorities to carry out repair works.As a result of the study, it was found that the prisons of the regimental cities and Hlukhiv in the middle of the XVIII century usually consisted of a prison, an upper (1-2 huts) and a lower jail and a building for security. Sometimes houses of local residents were used to hold the prisoners. Regardless of the location of criminals, prisoners regularly suffered from the weather (cold, snow, rain). Not much better were the conditions for service in the guardians of the prisoners.Natural factors always destroyed wooden structures, even in the absence of fires. The fence around the prison and its walls over time were rubbed, and criminals were given the opportunity to escape. It is worth noting that the construction became much more unusable due to constant attempts to escape criminals. The practice of partial repair of prisons could not solve the problem, and for some time again, there was a need to upgrade the institution.According to the author, there were three ways of providing materials for the construction or repair of prisons. In the first case, resources were taken from the residents of the regiment on the basis of distribution, which was conducted by the regimental office with the consent of the capital authorities. In the second - the money from the treasury was used only for those materials that were not in the inhabitants of the regiment. The third option for carrying out repair works was that the state treasury assumed the funds for the purchase of all materials.
