SEMIOTICS OF BUANG-BUANG AE’ TRADITION: RELATIONSHIP BETWEEN HUMANS, MODERN MEDICINE, AND ISLAM ON COASTAL COMMUNITIES IN DABONG, KUBU RAYA, WEST KALIMANTAN
Authors: Abong Rustam , Hakim Muhammad Luthfy , Darmadi Didi
Published: April 2019

This study aims to reveal the relationship between humans and nature. Researchers used data from Buang-buang Ae’ tradition discussed in terms of semiotics to see Buang-buang Ae’ Tradition': Relationship Between Humans, Modern Medicine, and Islam in Coastal Communities in Dabong, Kubu Raya, West Kalimantan. Data obtained from the field shows that: 1. A waste of tradition is aimed at treatment, facilitating the birth process so that it is not difficult (difficult) and so that it is not disturbed by spirits. Although now there is community who do not believe anymore, they are still only carried out as a condition or formality. 2. The semiotic of Buang-buang Ae’ tradition is a myth that describes human relationships with nature and the creator that takes place in balance and moderation. 3. From modern medicine, the community has been able to accept the presence of midwives as partners of traditional birth attendants in the labor process for Dabon people, because both of them aim to save the lives of those who want to give birth and their babies. The Prophet Khaidir is considered as a horizontal and vertical axis because the water ruler represents Allah. So that with the tradition of Buang-buang ae' is considered capable of connecting ordinary people with Prophet Khaidir. Moreover, in the pronunciation of word ‘mantra’, there is a sentence of ‘Assalamu ‘alaikum, Prophet Khaidir’ and ‘Bismillahirrahmanirrahim’, which proves Islamization by previous preachers, known as Sufistic Islam or Muslim moderation. There are some informants who argue that the tradition of Buang-buang ae’ contains syirk, but it is limited to the implementation of this tradition.

Authors: Kausar A.
Published: April 2019

In this study, novel polyacrylonitrile/polystyrene (PAN/PS) blend has been prepared and reinforced with carbon nanoparticle to form polyacrylonitrile/polystyrene/carbon nanoparticle (PAN/PS/CNP) nanocomposite foam. Acid-functional carbon nanoparticle (0.1-3 wt.%) was used as nano-reinforcement for PAN/PS blend matrix. 2’-azobisisobutyronitrile was employed as foaming agent. The PAN/PS/CNP nanocomposite foams have been tested for structure, morphology, mechanical properties, thermal stability, non-flammability, water uptake, and toxic ion removal. Field-emission scanning electron microscopy and transmission electron microscopy exposed unique nanocellular morphology owing to physical interaction between the matrix and functional CNP. PAN/PS/CNP 0.1 Foam with 0.1 wt.% nanofiller had compression strength, modulus, and foam density of 41.8 MPa, 22.3 GPa, and 0.9 mgcm−3, respectively. Nanofiller loading of 3wt.% (PAN/PS/CNP 3 Foam) considerably enhanced the compression strength, modulus, and foam density as 68.2 MPa, 37.7 GPa, and 1.9 mgcm−3, respectively. CNP reinforcement also enhanced the initial weight loss and maximum decomposition temperature of PAN/PS/CNP 3 Foam to 541 and 574 ºC, relative to neat foam (T0 = 411 ºC; T10 = 459 ºC). Nanocomposite foams have also shown excellent flame retardancy as V-0 rating and high char yield of up to 57% were attained. Due to hydrophilic nature of functional carbon nanoparticle, water absorption capacity of 3 wt.% nanocomposite foam was 30% higher than that of pristine foam. Moreover, novel foams were also tested for the removal of toxic Pb2+ ions. PAN/PS/CNP 3 Foam has shown much higher ion removal capacity (166 mg/g) and efficiency (99 %) than that of PAN/PS foam having removal capacity and efficiency of 90 mg/g and 45 %, respectively.
The Influence of Laser Alloying of Ti13Nb13Zr on Surface Topography and Properties
Authors: Tęczar P. , Majkowska-Marzec B. , Bartmański M.
Published: April 2019

The laser alloying is a continually developing surface treatment because of its significant and specific structuration of a surface. In particular, it is applied for Ti alloys, being now the most essential biomaterials’ group for load-bearing implants. The present research was performed on the Ti13Nb13Zr alloy subject to laser modification in order to determine the treatment effects on surface topography and its some mechanical properties like nanohardness, Young’s modulus, roughness. A pulse laser Nd:YAG was applied at three different laser pulse regimes: either 700 W, 1000 W or 1000 W treatment followed by 700 W modification at a pulse duration of 1 ms. The surface topography and morphology were examined using light microscopy and scanning electron microscopy with spectroscope of X-ray energy dispersion. The mechanical properties were determined by nanoindentation tests and surface roughness with a use of profilograph. The wettability was tested with a goniometer. The obtained results demonstrate complex behavior of the material surface: decrease in penetration distance and increase in hardness after first laser treatment, maintenance of this trend when machining using a higher laser pulse power, followed by an increase in penetration and decrease in hardness after additional laser treatment at lower power input, due to which a surface with fewer defects is obtained. The change in Young’s modulus follows the change in other mechanical properties, but not a change in roughness. Therefore, the observed hardening with the increase of the laser pulse power and then a small softening with the use of additional treatment with lower power can be attributed to some processes of remelting, diffusion and crystallization, sensitive to the previous surface state and heat energy flux. Despite that, the laser treatment always caused a significant hardening of the surface layer.

Published: April 2019

The paper presents the results of the investigation of microstructure of the welded X5CrNiCuNb16-4 (17-4PH) steel after solution treatment and aging at 620°C for different periods. The microstructure and the phase composition of the steel was investigated using light microscopy (LM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM) and the X-ray diffraction (XRD). Hardness was measured for samples aged at different times. Density distributions of Cu precipitates were established. The investigation has shown that the microstructure of the X5CrNiCuNb16-4 steel welds after aging at 620 ° C consists of tempered martensite, fine Cu precipitates and austenite. It was observed that the size of the Cu precipitates increases with increasing the aging time, what affects the decrease of hardness. Simultaneously, the quantity of reversed austenite increases with increase of aging time. It was revealed that enrichment of the austenite in Ni, Cu and C affects the increase of Ms, but this factor does not determine the stability of austenite.

Published: April 2019

The aim of the study was to find associations between the process of neoplastic transformation and mtDNA mutations/polymorphisms, i.e. factors with potential prognostic significance, and to determine their impact on the biochemical properties, as well as structural, and functional properties of proteins. Blood and neoplastic tissue samples were collected from a 9-year-old Labrador dog with a diagnosed malignant mammary tumour. Next-generation genome sequencing (NGS) of the entire mitochondrial genome was performed using Illumina technology, and bioinformatics analyses were carried out. This is the first report demonstrating the application of NGS in the analysis of the canine mtDNA genome in neoplastic disease. The proposed strategy is innovative and promising. For the first time in the literature, the sequence of 29 genes was analysed to determine their association with the prevalence of tumour. In total, 32 polymorphic loci and 15 mutations were identified. For the first time, as many as 24 polymorphisms and all the mutations have been described to be associated with the neoplastic process in dogs. Most polymorphisms/mutations were found in the D-loop (31% of the polymorphisms and 93% of the mutations) and the COX1 gene sequence (16% of the polymorphisms). Blood or cancer heteroplasmy was noted in 93% of the mutations. Four of the 18 polymorphisms detected in the protein-coding genes were non-synonymous polymorphisms that have not been described in the literature so far (m.T7593C in COX2, m.G8807A in COX3, m.A9911G in ND4L, and m.T13299A in ND5) but resulted in changes in amino acids in proteins. These mutations and polymorphisms can affect mitochondrial functions and may be a result of cell adaptation to the changes in the environment occurring during carcinogenesis. The replacement of “wild type” mtDNA by a mutated molecule may be an important phenomenon accompanying carcinogenesis.

Published: April 2019

The study of CT angiographies performed on a CT scanner GE LightSpeed VCT16 Slice CT revealed some morphological features of the ophthalmic artery related to origin, morphometry and the internal carotid arteries in the vicinity of this artery. The diameter of the left internal carotid artery under the origin of the ophthalmic artery was between 4.0-5.8 mm and that of the right ophthalmic artery at the same level was between 4.1-5.3 mm. Under the origin of the ophthalmic artery, the internal carotid arteries were larger in diameter on the leftside in 80% of cases, with differences of 0.1-0.3 mm, and on the right side these differences were between 0.1-0.2 mm, 20% of cases. The diameter of the left internal carotid artery above the origin of the ophthalmic artery was 3.7-5.0 mm, and the origin of the right carotid artery at the same level was 3.8-5.0 mm.
AmpC beta-lactamase enzymes are ubiquitous in catfish (Clarias gariepinus) cultured in the Nigerian catfish grow-out pond systems
Authors: Akinnibosun Faith I. , Imade Odaro S.
Published: April 2019

This research was performed to ascertain the ubiquity of bacterial pathogens which hyper-produced AmpC β-lactamase enzymes in adult catfish cultured in the Nigerian catfish grow-out pond systems. Phenotypic and molecular methods were used to isolate and identify bacterial pathogens that hyper-produced AmpC β-lactamase enzymes. The AmpC β-lactamase enzymes produced by the bacterial pathogens were subsequently characterized by BLASTX and RPS-BLAST bioinformatics software as well as with the Cn3D molecular modelling software. Findings from the present study indicated that pathogenic bacterial strains which hyper-produced the AmpC β-lactamase enzymes were isolated from 49 catfish samples out of the 54 catfish samples which were examined. The pathogenic bacterial strains were mainly identified as Citrobacter freundii MGH 150, Enterobacter cloacae NG 14, and Enterobacter cloacae subspecies dissolvens HKE 15. The AmpC β-lactamase enzymes produced by the bacterial pathogens were also respectively identified as cephalosporinase hydrolyzing class C CMY-LAT-MOX-ACT-MIR-FOX, CMY2/MIR/ACT/EC family class C beta-lactamase, and CMY2/MIR/ACT/EC family class C beta-lactamase. The presence of AmpC enzymes that are hyper-produced by bacterial pathogens which were isolated from almost all the catfish examined calls for urgent monitoring/surveillance of the Nigerian catfish ponds by the relevant regulatory agencies.

A note on testing hypotheses concerning interaction with special reference to a graphical presentation in the space of canonical variates
Authors: Kayzer Dariusz
Published: April 2019

Results of ecological studies that involve the use of multivariate analysis of variance techniques for testing various hypotheses, interesting from the point of view of comparing the linear functions of parameters, were considered. For testing the most interesting hypotheses on a variety of interaction effects and on contrasts of class means, the application of a multivariate test statistic is recommended. Canonical variate analysis is used for graphical presentation of the results of multidimensional experiments. In this paper it is shown how a generalized form of canonical variate analysis can be useful to reveal which parametric functions of a multivariate analysis of variance model are responsible for rejecting the linear hypothesis. As an example, an analysis was made of an ecological study of trace element accumulation in plants of Italian ryegrass as a method of biomonitoring of air pollution.

Performance Characteristics of Buildings in the Assessment of Revitalization Needs
Authors: Nowogońska Beata
Published: April 2019

Performance characteristics are an indicator of both, the technical as well as aesthetic state of buildings. Aesthetic needs are in disagreement with the merciless aging process. The beauty of a city is formed not only by the original forms of new residential buildings, but also by existing tenement housing; thus preserving their aesthetics becomes a necessity. One of the most important problems connected with using any building, but especially a residential building, is ensuring an adequate technical condition. Process of revitalization of residential buildings is connected with familiarity with the technical problems of passing. However, the secret of lasting is found, above all, in the propagation of aesthetics. The diagnosis of the technical condition is an initial stage of renovating historical buildings. Conclusions drawn from the diagnosis are a basis for planning revitalization works.
The Effect of an Electronic Exchange on Prices and Return Volatility in the Fine Wine Market
Authors: Czupryna Marcin , Oleksy Paweł
Published: April 2019

Fine wine has become an attractive alternative asset class in recent decades. In our study, we take the market microstructural perspective and verify how innovations in trading infrastructure affect the fine wine market. More specifically, we examine the average prices and the return volatility of fine wines traded on three different trading systems: automated electronic exchange, auctions and over-the-counter agreements (the OTC market). Our findings confirm an important role of a fully automated, cost-effective wine exchange in improving pricing efficiency and reducing market risk. This may constitute useful information for professional wine traders and institutional investors, who might consider shifting from less transparent trading systems into an automated on-book venue. This may also be a valuable indication for the future development of trading infrastructure in wine and other agricultural commodity markets.
Understanding the Informal Economy in Practice – Evidence from Bosnia and Herzegovina
Authors: Efendic Nirha , Pasovic Edin , Efendic Adnan S.
Published: April 2019

This paper provides insights into the informal economy of Bosnia and Herzegovina (BiH), a post--conflict transition economy in the Western Balkan region aspiring to became part of the European Union. After the introductory section and literature review, we introduce the economic outlook of BiH and then provide evidence estimating the size of the informal economy, which is identified to be around 30% over the last couple of years. As the size of the informal economy is high and persistent, this implies that current policy approaches are not efficient in tackling this economic challenge. To understand how the informal economy operates in practice, we use data from two different surveys to assess tax morality, undeclared work and the structure of the participants in the informal economy. In the next section, we supplement the study with ethnographic insights. In particular, we identify how participants in the informal economy use it for different purposes and with different motives. This includes reliance on the informal economy as a survival strategy for households, as a way to supplement insufficient formal income, to compensate for economic insecurity, or to decrease costs of formal business by using “envelope wage” practices, but equally importantly to overcome formal institutional rigidities linked to current contradictory laws. Still, we find indications that the growth of informal business is converging to formalisation, as informality at some stages of business development becomes a burden to higher entrepreneurial growth aspirations.
Changes in the activity of ovine blood-derived macrophages stimulated with antimicrobial peptide extract (AMP) or platelet-rich plasma (PRP)
Authors: Wessely-Szponder Joanna , Szponder Tomasz , Bobowiec Ryszard , Michalska Joanna
Published: April 2019

Introduction: Antimicrobial peptides (AMP) are a large group of innate immune effectors, which apart from antimicrobial activity show immunomodulative properties. Platelet-rich plasma (PRP) is a source of autologous growth factors and is used for stimulation of bone and soft tissue healing. The purpose of this study was to assess the influence of PRP and AMP extract on ovine monocyte-derived macrophage cultures. Material and Methods: The study was conducted on ovine macrophages (Mfs) previously stimulated with LPS or dexamethasone and then with preparations of PRP or AMP. Following activation of the Mfs their morphological and functional features were assessed. Results: The study revealed pro-inflammatory influence of both examined preparations on Mfs cultures on the basis of morphology, ROS generation and arginase activity. Both preparations enhanced the pro-inflammatory response of cultured Mfs. Conclusion: This activity may intensify the antimicrobial action of Mfs, however, in cases of excessive and prolonged inflammation the use of these preparations should be limited.
The role of the novel in shaping a city’s imageand its choice as a tourist destination: The case of Łódź
Authors: Włodarczyk Bogdan , Duda Michał
Published: April 2019

Following in the footsteps of one’s favourite literary characters has become a significant part of tourism. It remains unknown, however, how many readers decide to visit the places described in a book, or what factors determine their decision to do so. This issue was analysed using the example of Łódź, the third largest city in Poland, which struggles with a negative image. In contrast to the research on literary tourism conducted so far, a questionnaire was completed by readers and not by tourists visiting the places described. The readers remembered many real locations and had become familiar with the city’s topography. Some declared their reluctance to accept its stereotypically ‘bad’ image, while others were fascinated with its ‘unique atmosphere’. To many the city has become more familiar and a significant number of readers have changed their perception of it as a result. By means of linear modelling, several factors were established which encouraged readers to visit the city for tourism purposes. These factors included the size of the reader’s home location, changes of opinion, and the first impression the book made. This research project clearly points to the significant role of the novel in creating images of the places it depicts.

Published: April 2019

The paper presents design, structure and architecture of the Universal Autonomous Control and Management System (UACAMS) for multipurpose unmanned surface vessel. The system was designed, installed and implemented on the multipurpose platform - unmanned surface vessel named HydroDron. The platform is designed to execute hydrographic survey missions with multi-variant configuration of the survey system (payload?) including multi-beam echo sounder, sonar, LiDAR, automotive radar, photographic and spectral camera systems. The UACAMS designed to provide flexibility that enables to operate on the different kind of surface platform and different type of functional payload. The full system configuration provides all four level of autonomy starting from remotely controlled to full autonomous mission. Each level can be implemented and run depending on user specific requirements. The paper explains the differences between autonomous and automatic mission and shows how the autonomy is implemented into the presented system. The full hardware structural design as well as the software architecture are described. In order to confirm initial assumptions the applied system was tested during four- week sea trials and tuned for a selected vessel to confirm assumptions. In the project, also the original shore control station was designed, produced and tested for the vessel, including specific user controls and radio communication system. Conclusions sum up all crucial points of the design and system implementation process.
Motion Control and Collision Avoidance Algorithms for Unmanned Surface Vehicle Swarm in Practical Maritime Environment
Authors: Zhuang Jiayuan , Zhang Lei , Qin Zihe , Sun Hanbing , Wang Bo , Cao Jian
Published: April 2019

The issue of controlling a swarm of autonomous unmanned surface vehicles (USVs) in a practical maritime environment is studied in this paper. A hierarchical control framework associated with control algorithms for the USV swarm is proposed. In order to implement the distributed control of the autonomous swarm, the control framework is divided into three task layers. The first layer is the tele-operated task layer, which delivers the human operator’s command to the remote USV swarm. The second layer deals with autonomous tasks (i.e. swarm dispersion, or avoidance of obstacles and/or inner-USV collisions), which are defined by specific mathematical functions. The third layer is the control allocation layer, in which the control inputs are designed by applying the sliding mode control method. The motion controller is proved asymptotically stable by using the Lyapunov method. Numerical simulation of USV swarm motion is used to verify the effectiveness of the control framework.
Water Entry of A Wedge Into Waves in Three Degrees Offreedom
Authors: Sun Shi Yan , Chen Hai Long , Xu Gang
Published: April 2019

The hydrodynamic problem of a two-dimensional wedge entering into a nonlinear wave in three degrees of freedom is investigated based on the incompressible velocity potential theory. The problem is solved through the boundary element method in the time domain. To avoid numerical difficulties due to an extremely small contact area at the initial stage, a stretched coordinate system is used based on the ratio of the Cartesian system in the physical space to the distance travelled by the wedge in the vertical direction. The mutual dependence of body motion and wave loading is decoupled by using the auxiliary function method. Detailed results about body accelerations, velocities and displacements at different Froude numbers or different waves are provided, and the mutual effect between body motion and wave loading is analysed in depth.
A Multi-Layered Potential Field Method for Water-Jet Propelled Unmanned Surface Vehicle Local Path Planning with Minimum Energy Consumption
Authors: Wang Shasha , Fu Mingyu , Wang Yuanhui , Zhao Liangbo
Published: April 2019

Focusing on the influence of wind and surface currents on local path planning in the marine environment, a multilayered potential field (MPF) method is proposed to minimize the energy consumption of a water-jet propelled unmanned surface vehicle (USV). A synthetic environment framework that can incorporate the information of the base potential field layer and the environment layer is constructed first. This framework provides a base for minimizing the energy consumption of the water-jet propelled USV through proper force weighting. For the purpose of USV path planning, the traditional potential field method is extended by including the velocity information of the USV and the approached obstacles to avoid collisions with dynamic obstacles. The proposed method integrates kinematic control to prevent considering the vehicle as a point mass or rigid body. Finally, simulation and comparison experiments are performed to demonstrate the energy-saving efficiency of the proposed local path planning approach for the water-jet propelled USV.
Analysis of County Geoportals in Terms of Opportunities to Purchase Data of the Register of Real Estate Prices and Values Online
Authors: Halik Łukasz
Published: April 2019

We live in an information society for which the Internet, as a global system of connections between computers and, consequently, databases stored in them, plays a highly important part. Hence, more and more real property data are available. This article is devoted to the analysis of the opportunities to purchase the Register of Real Estate Prices and Values (RREPV) online from county geoportals. RREPV is one of the sources of information used in the process of real estate value estimation. Pursuant to § 74 of the Regulation on the Land and Property Register, the register is kept by the head of the county. There are 380 counties in Poland, including 66 city counties. Such a big number of administrative units in Poland, along with a great variety of different information and communication systems used for keeping RREPV, results in the fact that online access to the register data is not possible everywhere. The aim of the paper is to present the spatial layout of counties which: created the opportunity to access the National Geodetic and Cartographic Resource data via county geoportals, launched special modules for handling real estate appraisers and made it possible to purchase RREPV data online.
Use of Investment Areas in Special Economic Zones in Poland in the Context of Planned Legislation Changes
Authors: Lizińska Wiesława
Published: April 2019

Boundaries of Special Economic Zones (SEZs) in Poland change constantly and preferential conditions, including attractive investment land sites, become important factors underlining a decision to choose the location of an enterprise.

Not all land allocated to investment projects within special economic zones in Poland has been developed and, in the context of planned amendments to the law regulating SEZs, it is worth asking whether the extent to which the zones are developed will change once the new law becomes effective. This is an important question because much of the investment land offered by SEZs is composed of land plots ready to be developed.

The aim of this paper has been to diagnose and assess the current level and changes in the development of investment areas within special economic zones in Poland. Attention was paid to potential consequences of the planned amendments in the Act on the Principles of Supporting New Investments to the management of areas enclosed in SEZs.

The research data were obtained from the Ministry of Development, published in Reports on the Implementation of the Act on Special Economic Zones (covering the years 2009-2016), and from the Polish Investment and Trade Agency (PAIH).

Published: April 2019

A significant workforce shortage of urologists available to serve the US population has been projected to occur over the next decade. Accordingly, much of the management of urologic patients will need to be assumed by other specialties and practitioners. Since primary care physicians are often first evaluate common urologic complaints, it makes sense that these physicians are in an excellent position to intervene in the management of these patients when appropriate. One of the most common complaints in urology is voiding dysfunction. The incidence of voiding dysfunction increases with age, with conservative estimates showing that over 50% of elderly patients suffer. Despite this high prevalence and its negative impact on quality of life, however, few seek or receive treatment, as many do not readily disclose these impactful yet personal symptoms. We sought to summarize the typical presentation, evaluation, assessment and therapeutic options for both male and female patients presenting with voiding dysfunction.

Published: April 2019

In production it is necessary to achieve conditions that lead to the minimum decarburization of a steel product’s surfaces. In this study, the hypo-eutectoid carbon steel C45 was annealed in air in the temperature range T
a = 600–1100 °C. The annealing times were between t
a = ½ h and t
a = 2 h. Different decarburizations occurred in different microstructures: ferrite–pearlite (T
a = 600 °C and 700 °C, T
a < AC1, no visible decarburization); ferrite–austenite (T
a = 760 °C, AC1 < T
a < AC3, visible decarburization); austenite at the beginning, ferrite– austenite after the incubation period (Ta = 850 °C, AC3 < T
a < 912 °C, visible decarburization); and austenite (T
a= 950 °C and 1100 °C, T
a> 912 °C, visible decarburization and overheating of steel). The edges were more prone to decarburization and to overheating. Stress relieving, normalizing and annealing before quenching of the steel C45 can be carried out in air.

Material e Métodos: Foram analisadas as seguintes variáveis: idade, sexo, dias de internação hospitalar, sinais e sintomas dos critérios de Frammingham, fatores de risco/comorbidades (Diabetes, hipertensão, etilismo, tabagismo, anemia, doença renal crônica e outros), exames (hemograma, Na+, ureia, creatinina, e e fração de ejeção – FE) e medicamentos prescritos na internação hospitalar. Resultados e Discussão: Neste estudo, verificou-se que a idade média foi similar ao estudo BREATH (64±16 anos). O período de internação hospitalar foi extenso nesta casuística. Estudos como ADHERE tem descrito que os DIH de pacientes com IC são em média de 4 a 5 dias para os casos não graves e de 9 a 11 dias para aqueles mais graves. Quanto a Fração de Ejeção (FE), observou-se maior prevalência de FE preservada nas mulheres em relação aos homens, que tiveram maiores taxas de FE reduzida. Correlacionando-se as variáveis clínico-demográficas com os dias de internação hospitalar (DIH), verificou-se associação estatisticamente significativa para hiponatremia e FE reduzida, e menor correlação com sexo, idade e anemia. Conclusão: Conclui-se que a IC com fração de ejeção reduzida (ICFER) foi mais associada ao sexo masculino, internação prolongada, idade avançada e sinais e sintomas dos critérios de Frammingham. Quanto ao tratamento empregado na ICFER, predominou o uso de IECA ou BRA, espironolactona e betabloqueador.

Published: April 2019

Türkiye çok sayıdaki akarsu ve gölleri, jeolojik ve topografik özellikleri ve farklı coğrafik bölgelerin kesişme noktasında olması nedeniyle bitki çeşitliliği yönünden dünyanın en zengin ülkeleri arasında yer almaktadır. Doğada besin zincirinin ilk halkasını oluşturan fitoplanktonik organizmaların ülkemiz iç sularında yayılış gösteren türlerinin belirlenmesi ve mevsimsel değişimlerinin incelenmesi yönünde yapılmış çok sayıda çalışma mevcuttur. Bununla birlikte iç suların büyük bir alana sahip olduğu Türkiye‘de, suların içme ve kullanımına yönelik önemli belirteçlerinden olan fitoplankton kompozisyonu belirlenmemiş, biyoçeşitliliği ortaya çıkartılıp kayıt altına alınmamış çok sayıda su kaynağı bulunmaktadır.

Ergene Nehri tatlısu yönünden zengin havzalarımızdan biridir ve bu alanda alg kompozisyonu ile ilgili yapılmış kapsamlı bir çalışma mevcut değildir. Bu amaçla Ergene Nehri‘ni besleyen yan ve ana kollarda (çay, dere, ırmak, nehir) dağılım gösteren Bacillariophyta üyesi mikroalglerin, mevsimsel olarak toplanıp teşhisleri ve sistematik pozisyonları saptanmış ve fotoğraflamaları yapılmıştır.

Çalışmanın sonucunda, Ergene Nehri ve nehri besleyen havzadaki akarsularda yayılış gösteren Bacillariophyta bölümüne ait Coscinodiscophyceae (4) ve Bacillariophyceae (110) olarak farklı sınıflara ait toplam 114 takson tespit edilmiştir.

Tespit edilen taksonların, mevsimsel ve örnekleme noktaları yönüyle nasıl dağılım gösterdiği ortaya çıkarılmıştır. Türkiye tatlısu alg florası açısından tespit edilen taksonların tamamı bölge için, 22 tanesi Türkiye için yeni kayıt olma özelliği taşımaktadır.
Kuru Üretim Zeytin Bahçelerinde Yağmur Suyu Hasadı Malç Uygulamasıyla Toprak ve Su Muhafazasının İncelenmesi
Authors: Kuzucu Meryem
Published: April 2019

Su hasadı teknikleri kurak alanlarda yağmur sularını biriktirerek su sıkıntısının ve kuraklığın etkilerini azaltmanın yanı sıra, toprak ve su koruma açısından da yarar sağlamaktadır. Bu çalışmada, yağışların yetersiz olduğu yarı kurak iklime sahip Güneydoğu Anadolu bölgesinde, sulama olanağı bulunmayan genellikle eğimli arazilere tesis edilmiş zeytin bahçelerinde toprak ve su erozyonu kontrolünü sağlamak amacıyla, Negarim mikro havza yağmur suyu hasadı tekniği uygulanmıştır. Bu çalışmada; yağmur suyunun bitkinin kök bölgesinde birikimini sağlamak amacıyla Negarim adı verilen mikro havzalar içerisine yerleştirilen plastik örtü, taş örtü, mikro-havza yüzeyinin sıkıştırılması ve kontrol konularından oluşan 36 adet mikro-havzanın toprak ve su erozyonuna olan etkisi değerlendirilmiştir. Araştırmada 2009-2010 yılları boyunca yüzey akış ve sediment kayıpları ile bitki gelişimi ölçülmüştür. Araştırma sonuçlarına göre yıllık ortalama yağışı 250 ile 400 mm arasında değişen deneme alanında, 2 su yılı boyunca meydana gelen ortalama maksimum yüzey akış 6201 L/parsel ile plastik örtü konusunda, ortalama minimum yüzey akış 810 L/parsel ile taş örtü konusunda belirlenmiştir. Ortalama maksimum sediment kaybı 1163 g/parsel ile yüzey sıkıştırma konusunda, ortalama minimum sediment kaybı ise 673,5 g/parsel ile taş örtü konusunda ölçülmüştür. Mikro-havza yüzeyi plastik örtü ile kaplı olduğundan erozyon kontrolünü en iyi şekilde sağlayan uygulama plastik örtü olarak saptanmıştır. Plastik örtü konusu en iyi yüzey akışı gerçekleştirdiğinden bitki boyu gelişimi yönünden ortalama 107,5cm uzunluk ile en iyi uygulama olmuştur. Sonuç olarak kuru koşullarda ve eğimli arazilerde üretimi yapılan zeytin bahçelerinde Negarim mikro havza su hasadı tekniğinin ağaçların büyüme ve gelişimi arttırmanın yanı sıra toprak ve su muhafazası açısından da yararlı ve uygulanabilir bir teknik olduğu sonucuna ulaşılmıştır.

Physical and Virtual Performance: From The Black Ribbon, The Women in Black, to the Film Industry
Authors: Mirković Saša
Published: April 2019

This article aims to compare the physical and virtual performance embodied in the anti-war campaign Black Ribbon and Women in Black performances, and Hollywood actresses’ gowns at the prestigious award event, supporting the #MeToo campaign, as well as to prove that, except for the black color permeating them all, significant difference in the success of these performances is caused not only by technological advancement, but also by the circumstances and the context they take place in. The idea is to analyze in chronological review, using literature and archival material, the symbolism of the color black in performances connecting antiwar activists, citizens, the non-governmental sector and the film industry.
The article will deal with the motives behind the narratives of the mentioned actions, as well as the scope of these performances, from stopping a war, punishment of war criminals, to prosecution for years of sexual harassment of women. It will stress the importance of the constant fight against the culture of impunity in different areas, and the importance of the contribution of technological development during the past 30 years, for moving the above-mentioned ‘black color’ performances, from the real to the virtual world. Here, this shift will be symbolized by space-restricted performances ranging from mass street protest marches to #MeToo.

An Embodied Challenge to Femininity as Disciplinary Power in the Contemporary American Young Adult Sports Novels
Authors: Riestra-Camacho Rocío
Published: April 2019

The goal of this paper is to investigate the role of disciplinary power regimes of femininity in sporting institutions depicted in sports fiction. With a renewed interest in analyzing sports practices as specifically gendered, this paper addresses how contemporary narratives’ deeper address of the affective encounters of characters has reconfigured the sports literary panorama. As represented in Miranda Kenneally’s novel, Coming Up for Air (2017), friendship poses a challenge to the institutionalized, parental and gendered bodily vulnerability of sports. The analysis reveals how the adolescent body is manageable but can also contest, in direct questioning of the interests of authority. Enjoying friendship in sports, eventually, reveals paths towards more inclusive (bodily) practices in them. Finally, this paper speaks of the fact that juvenile fiction, traditionally considered an archive of negative influence on young readers’ behaviors, can exercise the opposite effect too.

In(k)scribed Identities: A Sociological Analysis of Catholic Croat Tattoos
Authors: Barabas Timea
Published: April 2019

For centuries, a number of Catholic Croat women from the territory of modern day Bosnia and Herzegovina have participated in a traditional form of tattooing. Rooted in the socio-political context marked by the rule of the Ottoman Empire (16th–19th century), it was believed that the symbols would offer protection against kidnapping by the Turks. While the practice carried on, outliving the context of its creation, it entered into a slow decline; today not more than a handful of people still bear these markings. Using interviews collected by Ilinčić (2016) as secondary data, I apply Foucauldian discourse analysis to follow the construction of meaning associated to tattoos along the interpersonal-intergroup continuum. Drawing upon structuralism and feminist theories about the body and social identity theory, I focus on how tattooing is used as a communicative signifier of social and or self-identity.
