COMPARATIVE STUDY OF GLUCOSE AND XYLOSE PRODUCTION IN ENZYMATIC HYDROLYSIS RESULT BY BATCH AND FED BATCH METHOD
Authors: Yudiastuti Silvia Oktavia Nur , Mardawati Efri , Kresnowati MTAP , Bindar Yazid
Published: December 2018

Xylose is a five carbon chain monosaccharide that can be used as a substrate in the fermentation of low-calorie xylitol. While glucose is a six carbon chain monosaccharide that can be processed into glucose syrup as a more stable natural sweetener in the food processing industry. Xylose is xylan monomer produced from hydrolysis of hemicellulose from plants or biomass woody waste.  While glucose is the result which is also produced in xylan hydrolysis by xylanase enzymatic hydrolysys. In the search for the source of hemicellulose, oil palm empty fruit bunch (OPEFB) as a solid waste from crude palm oil processing is a source that can be utilized in this research. OPEFB waste is abundant by the increasing world demand for vegetable oil. Considering the OPEFB enzymatic hydrolysis was a hetrogenous solid-liquid reaction, fed batch feeding of substrate was thought to improve the reaction performance. Hydrolysis experiments were performed at temperature 500C, pH 5 and for 96 hours hydrolysys time with substrate concentration at 15% and enzyme dose of 1%. The result showed that the feed-batch hydrolysis configuration provided higher yield of xylose and glucose than batch configuration but unsignificant.Keywords : Enzymatic Hydrolysis, Fed-batch, glucose, Xylan, Xylanase, Xylose.
Prostitución reglamentada, moral sexual y familia patriarcal en Junín, Provincia de Buenos Aires (1891-1936).
Authors: Orsi Agustín
Published: December 2018

El presente artículo aborda la situación de la prostitución femenina reglamentada, las concepciones sobre ella y el control de su ejercicio por parte de las autoridades estatales de la localidad bonaerense de Junín. Se analiza en función de su relación con el modelo de familia patriarcal que distintos sectores intentaron imponer en el país entre finales del siglo XIX y principios del XX. En este período adquirió una serie de rasgos específicos y una marcada relevancia debido a la dimensión y las características del desarrollo atravesado por el país y, particularmente, la localidad. Por una serie de concepciones fuertemente arraigadas en la época se concebía como una actividad fundamental para el mantenimiento de un orden social y de género específicos, pero que a su vez encarnaba algunos peligros. Por ello se optó por regularla a través de los municipios centrándose principalmente en aspectos morales, higiénicos y de seguridad.
Mujeres y participación política en Tlaxcala. Desempeño parlamentario 2013-2017
Authors: Cazarín Martínez Angélica
Published: December 2018

La participación política de las mujeres ha sido un tema de estudio recurrente desde diversas disciplinas y enfoques. Los estudios de género han diversificado su campo de análisis siendo uno de ellos el relativo a las cuotas de participación de mujeres para atender la subrepresentación en los órganos legislativos. En México, las cuotas han transitado del 70/30 por ciento en 2002, pasando por el 60/40 en 2008, hasta lograr la paridad 50/50 en la reforma política de 2014, contexto en el que se destaca el incremento gradual en el desempeño parlamentario de las mujeres diputadas a pesar del número de mujeres en funciones. El presente documento hace un análisis del caso de las mujeres diputadas en la LXI Legislatura del Congreso del Estado de Tlaxcala, con el objetivo principal de conocer las condiciones de equidad sustantiva en las que ejercen sus cargos, así como describir y contextualizar su trabajo y desempeño legislativo en dicho periodo.
Empobrecimiento de las clases medias y la persistencia de la pobreza en México
Authors: Millán Henio
Published: December 2018

La incidencia de la pobreza en México muestra niveles similares a los de 1992. Sin embargo, su evolución exhibe dos períodos claramente diferenciados: en el primero (1996-2006) declinó permanentemente, mientras en el segundo (2006-2014) aumentó. A través de un ejercicio de descomposición, se prueba que el efecto redistributivo cambió de naturaleza en los dos períodos: en el primero, las transferencias eran entre no pobres, mientras que en el último ocurren de pobres a no pobres.
An Approach for Computing the Heat Sources in Logs Subjected to Freezing
Authors: Deliiski Nencho , Tumbarkova Natalia
Published: December 2018

This study suggests an approach for computing the specific energies of the internal heat sources in logs subjected to freezing. The approach maximally considers the physics of the freezing processes of both the free and the bound water in wood. It reflects the influence on the mentioned energies of the wood density above and below the hygroscopic range. It also considers the icing degrees formed separately by both the free and bound water in the logs, as well as the influence of the fiber saturation point of each wood species on its respective amount of non-frozen water depending on temperatures below 272.15 K. Mathematical descriptions of the specific heat energies Qv-fw and Qv-bw released in logs during free water freezing in the range from 0 °C to −1 °C and of the bound water below –1 °C, respectively, have been executed. These descriptions are introduced in own 2D non-linear mathematical model of the freezing process of logs. For the solution of the model and computation of the energies Qv-fw and Qv-bw, a software program based on the suggested approach and mathematical descriptions was prepared in FORTRAN, which was input into the calculation environment of Visual Fortran. With the aid of the program, computations were completed to determine the energies Qv-fw and Qv-bw and their sum, Qv-total of a beech log subjected to freezing. The beech log had a diameter of 0.24 m, a length of 0.48 m, an initial temperature of 20.5 °C, a basic density of 683 kg·m−3, and a moisture content of 0.48 kg·kg–1 during its 30 hours in a freezer at approximately −30 °C.
Entropy as a measure of dependency for categorized data
Authors: Skotarczak Ewa , Dobek Anita , Moliński Krzysztof
Published: December 2018

Data arranged in a two-way contingency table can be obtained as a result of many experiments in the life sciences. In some cases the categorized trait is in fact conditioned by an unobservable continuous variable, called liability. It may be interesting to know the relationship between the Pearson correlation coefficient of these two continuous variables and the entropy function measuring the corresponding relation for categorized data. After many simulation trials, a linear regression was estimated between the Pearson correlation coefficient and the normalized mutual information (both on a logarithmic scale). It was observed that the regression coefficients obtained do not depend either on the number of observations classified on a categorical scale or on the continuous random distribution used for the latent variable, but they are influenced by the number of columns in the contingency table. In this paper a known measure of dependency for such data, based on the entropy concept, is applied.

Published: December 2018

Cryptographic protocols are the backbone of information security. Unfortunately the security of several important components of these protocols can be neglected. This causes violation of personal privacy and threats to democracy. Integration of biometrics with cryptography can overcome this problem. In this paper an enhanced session key agreement protocol which uses the data derived from iris signature is suggested to improve the security of biometric based applications like e-Passport, e-Driving license, etc. The authenticity and security properties of the proposed protocol are analyzed using ProVerif tool and demonstrate it satisfies the intended properties.
Eco-physiological responses and biochemical characterization of different accessions of Corchorus olitorius (L.)
Authors: Giro Andrea , Ferrante Antonio
Published: December 2018

Corchorus olitorius (L.) is one of the main crops for fibre production, cultivated in tropical and subtropical environments, from Africa to Japan, across the Middle East and India. In developing countries, the leaves are used as a medicine and also as food. In this study, we evaluated the physiological responses of nine accessions of C. olitorius in order to nominate the most suitable one for introduction into southern Europe. African and Asian accessions obtained from the Leibniz Institute IPK gene bank were analysed for their photosynthetic variables and quality traits during cultivation. Accessions from Africa, in particular those from Egypt and Libya, showed higher intrinsic water-use efficiency. However, at high temperatures, the Japanese accession also showed a high level of water-use efficiency, as evidenced by the high carbon fixation rate. Chinese and Indian accessions showed a reduction in growth performance, although a high concentration of antioxidants in the leaves and biomass accumulation have been reported in those accessions. C. olitorius demonstrated an intrinsic attitude to adaptation; according to their subtropical origin, all of the plants grew at sub-optimal status (Fv/Fm). These data, however, do not seem to compromise the potential of these plants as a crop for growing in southern Europe. Moreover, their introduction can be based solely on their biochemical quality traits.
Psychological obstacles to multiculturalism: how stereotypes and mechanisms of defence may cause adverse behaviours to multiculturalism.
Authors: Amoretti Guido
Published: December 2018

Migration flows are part of human history. The process of globalization, if on the one hand it seems to favour the movement of human beings, on the other hand it is creating the conditions for the recovery of migratory flows, especially within some areas of the world and, in part, directed towards advanced development countries. This creates problems of acceptance on the part of the host with respect to the customs and habits of the guest. Resistance to reception, used for political ends by populist parties, has deep roots that have to do with psychological and social factors: defence mechanisms, stereotypes and prejudices. The article stresses the importance of training in overcoming these obstacles to building a society that is first multicultural and then intercultural.
Detecting Reporting Errors in Data from Decentralised Autonomous Administrations with an Application to Hospital Data
Authors: van Delden Arnout , van der Laan Jan , Prins Annemarie
Published: December 2018

Administrative data sources are increasingly used by National Statistical Institutes to compile statistics. These sources may be based on decentralised autonomous administrations, for instance municipalities that deliver data on their inhabitants. One issue that may arise when using these decentralised administrative data is that categorical variables are underreported by some of the data suppliers, for instance to avoid administrative burden. Under certain conditions overreporting may also occur.

When statistical output on changes is estimated from decentralised administrative data, the question may arise whether those changes are affected by shifts in reporting frequencies. For instance, in a case study on hospital data, the values from certain data suppliers may have been affected by changes in reporting frequencies. We present an automatic procedure to detect suspicious data suppliers in decentralised administrative data in which shifts in reporting behaviour are likely to have affected the estimated output. The procedure is based on a predictive mean matching approach, where part of the original data values are replaced by imputed values obtained from a selected reference group. The method is successfully applied to a case study with administrative hospital data.
The characteristics of geographical information systems in terms of their current use
Authors: Mierzejowska Aleksandra , Żogała Monika
Published: December 2018

From the beginning of human existence, man collected and analysed information about the space that surrounded him. Nowadays, due to the huge amount of data, it would be impossible without geographic information systems. According to the definition, the main function of GIS (Geographic Information Systems) is to collect, process, integrate, analyse and present data directly collected in the database or obtained through analysis. The basis of each information system’s functioning is the collection of relevant data about real-world objects, in terms of their completeness, quality and reliability. Due to the very rapid development of information technology, GIS systems have found a wide application, eg. in spatial planning, real estate management, administration, infrastructure management and many other areas of life. The authors within the article have made a detailed review of the current using of GIS, with particular emphasis on the mining industry. In the latter, particular attention was focused on the use of this type of tools to monitor and analyse the effects of mining activities. At the same time, the authors indicated new possibilities related to the application of geographic information systems in this branch.
Morphometric analysis and sub-watersheds prioritization of Nagmati River watershed, Kutch District, Gujarat using GIS based approach
Authors: Said Saif , Siddique Rabab , Shakeel Mohammad
Published: December 2018

Morphometric analysis of any watershed and its prioritization is one of the important aspects of planning for implementation of management programmes. Present study evaluates the quantitative morphometric characteristics of Nagmati River watershed in Kutch District of Gujarat by utilizing Cartosat-1 data (CartoDEM). In all 19 aerial and 6 linear morphometric parameters of the watershed have been evaluated. Drainage map of the study area reveals a dendritic drainage pattern with sixth order stream network comprising 492 numbers of streams and confining an area of 129.41 km2. Mean bifurcation ratio (Rb) and stream length ratio (RL) of the watershed evaluated are 3.44 and 0.54 respectively which corroborates the fact that drainage pattern is not influenced by the geological evolutions and disturbances in the recent past. The drainage density of 2.68 kmꞏkm−2 indicates impermeable subsoil material with sparse vegetation and moderate to low relief. Elongation ratio of 0.956 infers the basin to be closer to a circular shape. The geologic stage of development and erosion proneness of the watershed is quantified by hypsometric integral (HI) bearing value as 0.5, indicating the landscape to be uniform and in early mature stage. The study prioritizes eight sub-watersheds as high, medium and low for taking up soil and water conservation activities. Hence, remote sensing applications proved to be highly useful in extracting the precise data for the evaluation and analysis of watershed characteristics.

Published: December 2018

En los últimos años en la Amazonía peruana se ha venido desarrollando la piscicultura de especies nativas de gran potencial, destacándose al “boquichico”, Prochilodus nigricans como una de las especies más promisorias. Este pez en cautiverio puede estar sometido a grandes niveles de estrés lo que puede influenciar negativamente en su resistencia contra infecciones parasitarias. A pesar de su enorme importancia económica, poco o casi nada se conoce con respecto a su fauna parasitaria. Por tanto el presente estudio pretende identificar los monogenoideos branquiales que parasitan a juveniles de P. nigricans provenientes del medio natural y de estanques de cultivo. Cuarenta branquias de P. nigricans provenientes del medio natural y cuarenta provenientes de un estanque de cultivo fueron analizados. Las especies de monogenoideos identificadas fueron: Apedunculata discoidea, Tereancistrum curimba y T. toksonum. Mayor número de indivíduos fue registrado en peces provenientes del médio natural. El presente estúdio registra por primera vez estas tres espécies en P. nigricans. La presencia de las mismas espécies de monogenoideos en peces provenientes de ambos ambientes despierta uma alerta a los piscicultores de la región, ya que bajo condiciones inadecuadas de cultivo, proliferaciones masivas de estos parasitos pueden ocurrir, colocando en riesgo la salud y calidad de los peces.

Authors: PEREIRA Jeffson Nobre , MOREY Germán Augusto Murrieta , MALTA José Celso de Oliveira
Published: December 2018

Branchiurans are parasites from the buccal cavity, gills, skin, and fins of various fish species. The Neotropical region has one of the highest diversity of branchiurans. On Arapaima gigas, only four species of branchiurans have been reported. The present study improves the knowledge on host and geographical range of Dolops striata. Fish were collected from a fish farm in the State of Pará, Brazil. All A. gigas were parasitized by Dolops striata, which were collected from the fins and body surface. This is the first record of D. striata in A. gigas. The high prevalence detected warns the possibility of an increase in the number of D. striata infesting A. gigas, which may cause some problems for fish-farmers.

Published: December 2018

Interspecific cross was made between the common sunflower inbred line HA89 and an accession of wild Helianthus nuttallii (2n=2x=34) resistant to the most harmful disease complex and tolerant to drought and high temperature. The recombinant inbred line was a BC1F15 progeny. The most remarkable feature observed was the vigorous plant habit that manifests itself in measurable morphological characters such as increment plant height, stem diameter and diameter of the head. The line was non-branched (monocephalic) without anthocyanin pigmentation and possessed good agronomic characteristics. Along with the morphological and reproductive traits, some biochemical characteristics related to antioxidant activity were associated to wide hybridization. The overall characteristics of HA-Hnutt line make it a useful plant material for research on interspecific hybridization in Helianthus genus.

Published: December 2018

To investigate some interesting functional properties of Bacillus spp. in cocoa fermentation processing, 702 strains of Bacillus sp. strains were isolated from six main Ivorian cocoa producer regions. Three mains technological and useful properties for good cocoa beans fermentation were monitored. Among the 386 pectinolytic Bacillus spp. strains, 86.79% of them were confirmed for enzymes production in liquid medium. These 335 pectinolytic Bacillus strains displayed variety of pectinolytic activity with 50.45% of them producing both pectinase and polygalacturonase (PG) enzymes. Among these 169 strains, 70% displayed both the ability to acidify the medium and to degrade the citrate. In mimic conditions of pH and temperature variations as for fermentation heap, 11 strains were able to maintain their activity ranged within 2.12 ± 0.02 to 0.41 ± 0.03 Âµmol/min/mg of proteins for PG and 2.36 ± 0.03 to 0.25 ± 0.03 Âµmol/min/mg of proteins for pectinase. Two species (T10T2 and T6HS10) identified as Bacillus subtilus and Bacillus thuringiensis, were selected as the best based on pectinase production level. They were able to continuously produce both pectinolytic enzymes in different conditions of organic acids and ethanol contents. The highlighted properties in this study and the performance of these two strains may make them best candidate as starters for cocoa fermentation control.

A Coordinative Solubilizer Method to Fabricate Soft Porous Materials from Insoluble Metal-Organic Polyhedra
Authors: Carné-Sánchez Arnau , Craig Gavin A. , Larpent Patrick , guillerm vincent , Urayama Kenji , Maspoch Daniel , Furukawa Shuhei
Published: December 2018

Porous molecular cages have a characteristic processability arising from their solubility, which allows their incorporation into porous materials. Attaining solubility often requires covalently bound functional groups that are unnecessary for porosity, and which ultimately occupy free volume in the materials and decrease their surface areas. Here, we describe a method that takes advantage of the coordination bonds in metal-organic polyhedra (MOPs) to render insoluble MOPs soluble by reversibly attaching an alkyl-functionalized ligand. We then use the newly soluble MOPs as monomers for supramolecular polymerization reactions, obtaining permanently porous, amorphous polymers with the shape of colloids and gels, which display increased gas uptake in comparison with materials made with covalently functionalized MOPs.
Correspondence: Hydrogen Bond to Gold? 1H NMR is Not a Proof of Hydrogen Bonds in Transition Metal Complexes
Authors: Vícha Jan , Foroutan-Nejad Cina , Straka Michal
Published: December 2018

Illusive AuI/III···H hydrogen bonds and their effect on structure and dynamics of molecules have been a matter of debate. While a number of X-ray studies reported gold compounds with short AuI/III···H contacts, a solid spectroscopic evidence for AuI/III···H bonding has been missing. Recently, Bakar et al. (NATURE COMMUNICATIONS 8:576) reported compound with four short Au···H contacts (2.61­–2.66 Å; X-ray determined). Assuming the central cluster be [Au6]2+and observing the 1H (13C) NMR resonances at relevant H(C) nuclei deshielded with respect to precursor compound, the authors concluded with reservations that “the present Au···H–C interaction is a kind of “hydrogen bond”, where the [Au6]2+serves as an acceptor”. Here, we show that the Au6cluster in their compound bears negative charge and the Au···H contacts lead to a weak (~1 kcal/mol) auride···hydrogen bonding interactions, though unimportant for the overall stability ofthe molecule. Additionally, computational analysis of NMR chemical shifts reveals that the deshielding effects at respective hydrogen nuclei are not directly related to Au···H–C hydrogen bonding .
Dynamic Order-Disorder Transition in the S = ½ Kagome Antiferromagnets Barlowite and Claringbullite

Published: December 2018

The nature of the structural phase transition in the quantum magnets barlowite, Cu4(OH)6FBr, and claringbullite, Cu4(OH)6FCl was investigated. These materials consist of parallel-stacked Cu2+ kagome layers, separated by planes that contain Cu2+ cations and halide anions. The structural transition is of an order-disorder type, where at ambient temperature the interlayer Cu2+ ions are disordered over three equivalent positions. In barlowite, the dynamic disorder becomes static as the temperature is decreased, resulting in a lowering of the overall symmetry from hexagonal P63/mmc to orthorhombic. The dynamic disorder in claringbullite persists to lower temperatures, with a transition to orthorhombic space group Pnma observed in some samples. Ab initio density functional theory calculations explain this temperature-dependent structural phase transition and provide additional insights regarding the differences between these two materials.

How lymph node stromal cells (LNSCs) shape peripheral T-cell responses remains unclear. We have previously demonstrated that murine LNSCs, lymphatic endothelial cells (LECs), blood endothelial cells (BECs), and fibroblastic reticular cells (FRCs) use the IFN-γ–inducible promoter IV (pIV) of the MHC class II (MHCII) transactivator CIITA to express MHCII. Here, we show that aging mice (>1 yr old) in which MHCII is abrogated in LNSCs by the selective deletion of pIV exhibit a significant T-cell dysregulation in LNs, including defective Treg and increased effector CD4+ and CD8+ T-cell frequencies, resulting in enhanced peripheral organ T-cell infiltration and autoantibody production. The proliferation of LN-Tregs interacting with LECs increases following MHCII up-regulation by LECs upon aging or after exposure to IFN-γ, this effect being abolished in mice in which LECs lack MHCII. Overall, our work underpins the importance of LNSCs, particularly LECs, in supporting Tregs and T-cell tolerance.

Abstract: University library plays an important role in serving all lecturers and students as it is a place where books and other information resources are collected and gathered for the purposes of reading and reference. Â AsÂ time goes by, university libraries have gradually open to the public to fully make use of its function as an educational and social platform. The socialized service of university library has the advantages of promoting cultural virtue and moral integrity to the public. However, there remain many issues during the development of socialized service in the university library. Â Besides analyzing the difficulties and obstacles faced in socialized services of the university library, this paper aims to provide countermeasures to solve the problems.Â

Este trabalho objetiva analisar a prática docente do curso de Ciências Contábeis de uma universidade do Nordeste. A pesquisa classifica-se como: descritiva, pois apresentou características da prática docente do curso; abordagem qualitativa, uma vez que analisou a percepção dos contadores atuantes no mercado de trabalho e professores em relação à prática docente do curso. Quanto aos procedimentos, tratou-se de um estudo bibliográfico com embasamento em literaturas publicadas, pois foram utilizados questionários e entrevistas semiestruturadas para comparação dos resultados com as literaturas. No que diz respeito aos resultados, foram analisados a partir dos discursos e sentimentos transmitidos pelos entrevistados. Os dados revelaram a insatisfação dos contadores com relação à ausência de práticas contábeis durante as aulas, o que dificulta o ingresso dos futuros profissionais no mercado de trabalho. Relataram ainda que o curso está mais voltado à formação de acadêmicos. Identificou-se na pesquisa que os contadores e professores acreditam ser necessário que estes últimos obtenham experiências profissionais além do magistério, para aperfeiçoar suas práticas de ensino no curso de contabilidade.

QuEChERS metodu ile “Golden Delicious” ve “Starking Delicious” elma çeşitlerinde chlorpyrifos etken maddenin kalıntı analizi için 0.05, 0.5 ve 5.0 mg/kg seviyelerinde zenginleştirme yapılarak validasyon gerçekleştirilmiştir. Analizler yapıldıktan sonra LC-MS/MS kullanılarak kromatografik ayrıştırma yapılmıştır. Matris etkisini elimine etmek için matrisli kalibrasyon (MC) kullanılmıştır. Bu yüzden, MCGolden D ve MCStarking D kalibrasyonları kullanılmıştır. Metodun validasyonu, gerçeğe yakınlık (accuracy), kalibrasyonun doğrusallığı, geri alım, cihaz dedeksiyon limiti, metodun tespit limiti, tekrar edilebilirlik ve kesinlik gibi kriterler ile gerçekleştirilmiştir. Her iki çözücü kalibrasyon kurvesi ve her iki matris kalibrasyon eğrisi 5-200 pg/µl aralığında lineer olarak bulunmuştur. Golden D örneğinden geri alımı; %8.36-14.03 tekrar edebilirlik değerleri ile %70.87-112.99 arasında bulunmuştur (ortalama geri alım %89.32). Starking D elma örneği için ise geri alım; %1.96-12.88 tekrar edebilirlik değerleri ile  %69.08-100.3 arasında bulunmuştur (ortalama geri alım %79.82). Tüm metodun geri alımı %15.68 relatif standart sapma ile  %84.60 olarak bulunmuştur. Tüm bulgular olması gereken geri alım sınırlarına (%70-120) ve tekrar edebilirlik kabul oranı için belirtilen değerlere (RSD ≤% 20) uygundur.

Published: December 2018

Sentetik açıklıklı radarın (SAR)
güçlü bir yer gözlem aracı olduğu artık ispatlanmıştır. Son on yılda, faz bilgisini muhafaza
ederken birden fazla kutuplaşma durumunu ölçebilen SAR sensörleri geliştirilmiştir.
Polarimetrik SAR (PolSAR) adı verilen sistemler hem dikey hem de yatay
polarizasyonlu mikrodalga sinyalleri göndermekte ve almaktadır. Optik veriler
elektro-optik sensörler yardımıyla spektral yoğunluk açısından, hedeflerin
yansıtıcı ve dağıtıcı özellikleri hakkında çeşitli bilgi sağlarken SAR
verileri, polarizasyon durumu ile doğal ve insan yapımı nesnelerin geometrik
yapısı, yüzey pürüzlülüğü ve dielektrik özellikleri hakkında detaylı bilgiler
içerir. Bu çalışmada C-band
Sentinel-1A uydusunun ikili polarimetrik çok zamanlı uydu görüntülerinden dilim
birleştirme ile üretilen polarimetrik görüntülerin sınıflandırılmasında,
polarimetrik ayrışma analizinin uygulama kolaylığı ve polarimetrik imzaların
yorumlanabilirliği nedeni ile kontrolsüz sınıflandırma yöntemi tercih
edilmiştir. Çalışma kapsamında, daha
önce (Single Look Complex) SLC mod ikili polarimetrik görüntüler kullanılarak PolSAR
sınıflandırması ile test edilmemiş bölgede, çalışma
alanına ait Sentinel-1A uydusu 2014 ve 2018 yılları ikili polarimetrik çok zamanlı
SAR görüntüleri kullanılarak belirtilen hedef ve yöntemlerle, PolSAR görüntülerine
H-alfa ayrışma algoritması uygulanarak polarimetrik parametreler yorumlanmıştır.
Kontrolsüz sınıflandırma ile çalışma alanındaki değişimlerin ortaya konulması ve
görsel analizi sağlanmıştır. Sınıflandırma sonucunda genel sınıflandırma doğrulukları, 2014
yılı için % 88,5 ve 2018 yılı için %89,0 olarak hesaplanmıştır. 2014 ve 2018 yılları
için kentsel ve kırsal alandaki arazi değişimleri belirlenmiştir. Çalışma,
arazi kullanımı arazi örtüsü sınıflandırması için ikili polarimetrik C-band SAR
verilerinin yeteneklerini incelemeyi de amaç edinmiştir. Ayrıca çalışmanın
devamı niteliğinde, farklı bantta çalışan dörtlü polarimetrik SAR ve optik
görüntülerin birlikte kullanımının sınıflandırma analizine etkisi
araştırılacaktır.
Çanakkale Civarından Toplanan Lissotriton vulgaris (Linnaeus, 1758) (Amphibia: Urodela) Örneklerinde Mikronukleus Analizi ve Nuklear Anomaliler*
Authors: TAŞCI Bircan , TOK Cemal Varol
Published: December 2018

Bu
çalışmada, Çanakkale’nin iki farklı bölgesinden toplanan [Kalabakbaşı köyü 12
(5♂♂, 7♀♀), Kirazlı köyü 9 (4♂♂, 5♀♀)] Lissotriton
vulgaris örneklerinden hazırlanan kan preparatlarında genetik materyaldeki
hasarın göstergelerinden biri olan mikronukleus (MN) ve nuklear anomaliler (NA)
belirlenmiştir. Çalışmada
mikronukleusun yanısıra binukleat, tomurcuklu nukleus, loblu nukleus ve
çentikli nukleus olmak üzere 4 tip nuklear anomaliye ilaveten sitoplazmik
vakuol (SV) ve mikrosit saptanmıştır. İki lokalite arasında sırasıyla çentikli,
tomurcuklu ve loblu nuklear anomaliler bakımından istatistiki olarak yüksek
düzeyde anlamlı fark bulunmuştur. Nüklear anomali sayıları bakımından
Kalabakbaşı ve Kirazlı lokalitelerindeki L.
vulgaris dişi ve erkek popülasyonları kendi aralarında
karşılaştırıldığında, önemli derecede istatistiki fark bulunmuştur. Ayrıca
cinsiyet karşılaştırılması yapıldığında iki lokalitede de SV, MN ve NA sayısı
bakımından önemli fark bulunmadığı gözlemlenmiştir. Çalışmadan elde edilen
sonuçlar, Kirazlı bölgesindeki altın madeninde yapılan çalışmalardan dolayı genotoksik
maddelerin bulunabileceğini ve genotoksik hasarın göstergelerinden biri olan MN
oluşumlarının burada bulunan kirleticilerden kaynaklanabileceğini
düşündürmektedir.
Kompleks Etken Madde Oranına Bağlı Olarak ZnFe2O4 Filmlerin İncelenmesi
Authors: SARF Fatma , YAKAR Emin
Published: December 2018

Son yıllarda spinel ferrit malzemeler (MFe2O4; M= Fe,Ni,Co,Mg vb.) oldukça farklı alanlarda, örneğin indüktörler, manyetik sensörler, magneto-optik depolama ve kayıt cihazları vb., kullanımı ile dikkat çekmektedir. Spinel ferrit malzeme grubu içerisinde yer alan ZnFe2O4 (çinko-ferrit) yüksek direnci, mekanik stabilitesi ve düşük dielektrik kayıpları ile özellikle yüksek frekans uygulamalarında karşımıza çıkmaktadır. Basit sentezlenme sürecine ve düşük üretim/güç maliyetine sahip ZnFe2O4 malzemelerine olan ihtiyaç bu yöndeki araştırma ve geliştirme çalışmalarını arttırmaktadır.Bu çalışmada çinko-ferrit filmleri kimyasal banyo depolama ile ITO alttaşlar üstüne farklı oranlarda kompleks etken madde kullanılarak sentezlenmiştir. Kompleks etken madde olarak amonyak tercih edilmiştir. Filmlerin amonyak oranına ve dolayısıyla çözeltinin pH’ına bağlı olarak değişen yapısal, yüzeysel ve optik özellikleri sırasıyla XRD, SEM ve Uv-Vis/Raman spektroskopisi ile incelenmiştir. XRD spektrumlarından elde edilen veriler ışığında, kristalleşmenin amonyak oranı artışı ile birlikte arttığı tespit edilmiştir. SEM-yüzey morfoloji görüntüleri ile amonyak oranı değişiminin farklı biçimlerde nanoparçacıklar oluşumuna sebep olduğu gözlenmiştir. Ayrıca filmlerin optik özelliklerinin amonyak oranı artışı ile iyileştiği tespit edilmiştir.
