Відомо, що шавлія лікарська (ШЛ) має виражений протизапальний ефект, який можна порівняти з таким у нестероїдних протизапальних препаратів. Доцільним є з’ясування впливу екстрактів ШЛ на сечовидільну функцію нирок. Мета дослідження – вивчення впливу 11 різних екстрактів ШЛ на діурез у щурів за умов водного навантаження. Дослідження виконано за стандартною методикою Є. Б. Берхіна. Досліджувані екстракти вводили внутрішньошлунково (в/ш) в дозах 10, 15, 20, 50, 70 мг/кг (екстракти № 1, 2 і 3) і 10, 20, 50, 70 мг/ кг (екстракти № 4, 5, 6, 7, 8, 9, 10 і 11). Препарати порівняння – фуросемід (10 мг/кг, в/ш), гідрохлортіазид (50 мг/кг, в/ш), адіурекрин (2 ОД, підшкірно). Білих нелінійних щурів розподіляли в групи по 6 тварин. Діурез реєстрували через 2 і 4 год після водного навантаження. За результатами дослідження встановлено, що 10 з 11 екстрактів ШЛ виявляють антидіуретичні властивості. Досліджувані сполуки статистично значущо зменшували об’єм виведеної сечі на 15,7– 58,3 % порівняно з показником контрольних тварин (р < 0,05). Для екстрактів № 1, 2, 3, 6, 8, 9, 10 і 11 встановлено зворотний дозозалежний ефект, тобто, у разі зменшення дози (до 10–20 мг/кг) посилювалась антидіуретична дія. На відміну від цих екстрактів, екстракти № 4 і 5 виявляли антидіуретичну активність у всьому діапазоні досліджуваних доз (10–70 мг/кг). Екстракт № 7 у жодній з досліджуваних доз не чинив антидіуретичного ефекту. Зважаючи на те, що основним компонентом екстрактів ШЛ є фенольні сполуки, зокрема, гідроксикоричні кислоти, зроблено припущення, що в основі антидіуретичного ефекту є їхня здатність зменшувати синтез простагландинів. Амінокислоти L-лізин і L-аргінін у цьому випадку проявили потенціювальний ефект.

Мета дослідження – вивчення антиексудативних властивостей рідкого спиртово-водного екстракту листя аїру звичайного (Acorus calamus L.) (РСВЕЛА). РСВЕЛА був отриманий на кафедрі ботаніки НФаУ під керівництвом професора Т. М. Гонтової. Протизапальні властивості РСВЕЛА досліджені на білих безпородних щурах на моделях карагенінового та гістамінових набряків. Досліджуваний РСВЕЛА (0,5 мл / кг) і препарати порівняння, а саме: диклофенак натрію (у дозі 8 мг / кг), кверцетин (у дозі 11 мг / кг) і лоратадин (у дозі 1 мг / кг), на моделі карагенінового та гістаміновими набряків застосовували в лікувально-профілактичному режимі: внутрішньошлунково одноразово щодня протягом 5 діб до моделювання запалення й за 1 год до ін'єкції флогогену (карагеніну або гістаміну відповідно). Розвиток набряку спостерігали в динаміці за показником об'єму лапи, який визначали за допомогою цифрового плетизмометра. Через 24 год після введення флогогену в тварин визначали кількість лейкоцитів і ШОЕ. Встановлено, що на моделі карагенінового та гістамінового набряку РСВЕЛА чинить протинабрякову дію. Антиексудативна активність РСВЕЛА склала 68,9 % (р < 0,05) на 120 хв запалення та 79,5 % (р < 0,05) на 180 хв у разі карагенінового набряку. На моделі гістамінового набряку антиексудативна дія РСВЕЛА склала 50,8; 27,7 і 50,0 % відповідно на 30, 60 і 90 хв набряку. За виразністю антиексудативної дії, ступенем зниження ШОЕ та показника лейкоцитозу РСВЕЛА не поступається всім трьом препаратам порівняння: диклофенаку натрію, кверцетину і лоратадину. Таким чином, встановлено, що РСВЕЛА має антиексудативну дію, що є обгрунтуванням подальших досліджень з перспективою створення на його основі нових ефективних фітопрепаратів для профілактики та фармакокорекції запальних процесів.

Published: January 2020

Неспецифічна дія протипухлинної хіміотерапії на прилеглі до пухлини тканини сама по собі здатна погіршити стан організму додатково до наслідків розвитку неопластичного процесу і навіть справити вирішальну роль у виживанні організму. Тому актуальним є проведення паралельних досліджень впливу нових протипухлинних засобів на етапі доклінічних випробувань як на пухлини, так і на тканини того самого організму, які неуражені неопластичним процесом, для подальшої оптимізації хіміотерапії. Мета дослідження – вивчити вплив Іфітинібу на ДНК, РНК, білки хроматину, процеси фрагментації ДНК, вміст небілкових і пов’язаних з білками SH-груп у карциномі Герена та незмінених тканинах матки. Дослідження впливу Іфітинібу проводили на білих щурах-самицях лінії Вістар. Тварини були розподілені за методом рандомізації на 3 групи по 6 тварин у кожній: 1 – інтактні щури, 2 – негативний контроль (карцинома Герена), 3 – карцинома Герена + 29,93 мг/кг Іфітинібу. Вивчення впливу Іфітинібу на ДНК, РНК, білки хроматину, процеси фрагментації ДНК, вміст небілкових і пов’язаних з білками SH-груп у карциномі Герена та незмінених тканинах матки показало, що даний препарат вірогідно змінював більшість досліджуваних показників як порівняно з інтактними тваринами, так і з карциномою Герена без лікування. Специфічність впливу Іфітинібу на клітини пухлин була найвираженішою у випадку ДНК-фрагментації та змін вмісту небілкових і пов’язаних з білками SH-груп.

Pharmacotherapy of prostate cancer is an important part in combating oncologic diseases. This is very relevant, because prostate cancer is a cause of 10 % of deaths from all cancerous diseases in males. The aim of the study – to synthesize novel derivatives of 1-(41-isopropylphenyl)-4-(42-chlorophenyl)5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd]azulene-2-carboxylic acid arylamides and to evaluate their antitumor activity against PC-3 prostate cancer cells. By reaction of equimolar amounts of 2-methoxy-3,4,5,6-tetrahydro-7H-azepine with a-amino-4-chloroacetophenone chlorohydrate, 3-(4-chlorophenyl)-6,7,8,9- tetrahydro-5Н-imidazo[1,2-a]azepine was synthesized. By alkylation of a-bromo-4-іsopropylacetophenone in ethylacetate and following treatment of the obtained intermediary quaternary salt with excess of 5 % NaOH solution,1-(41-isopropylphenyl)-4-(42chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd] azulene was synthesized. By boiling it with equimolar amounts of correspondding arylisocyanates in dried benzol, an array of 1-(41-iso propylphenyl)-4(42-chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd]azulene-2-carboxylic acid arylamides were synthesized. Structure and purity of all compounds obtained were confirmed by data of MR1Н spectroscopy. Lipophilicity (LogP) of compounds 6 and 8 a-i was calculated with the ACD LogP program. Antitumor activity of 1-(41-isopropylphenyl)-4-(42-chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd]azulene-2-carboxylic acid (3-methylphenyl) and (3-methoxyphenyl)-amides was evaluated at in vitro test on prostate cancer PC-3 cell lines. It is indicated, that at concentration of 10–5 M these compounds exceed 5-fluorouracil as comparison drug in inhibiting PC-3 prostate cancer cells growth by 52.32 % and 3.93 % correspondingly. The data obtained substantiate feasibility of further studies of 1-(41-isopro pylphenyl)-4-(42-chlorophenyl)-5,6,7,8-tetrahydro-2,4а-diazacyclopenta[cd] azulene-2-carboxylic acid arylamides as new, potential antitumor medicines for prostate cancer treatment.

Authors: Załuski Dariusz , Tworkowski Józef , Krzyżaniak Michał , Stolarski Mariusz J. , Kwiatkowski Jacek
Published: January 2020

Camelina (Camelina sativa (L.) Crantz) is an alternative oilseed crop that is garnering increasing popularity due to its multiple applications and greater tolerance to adverse environmental conditions than oilseed rape. The study analyzed selected traits of 10 Canadian and Polish spring camelina genotypes grown in a field experiment in north-eastern Poland in 2015–2018. The greatest differences were observed in seed yield where the effect of weather and environmental conditions explained 72.7% of variance, the effect of genotype explained 5.9% of variance, and the effect of the genotype-by-environment interaction explained 5.7% of total variance. In contrast, 1000-seed weight was not affected by environmental conditions, and it was differentiated only by genotype which explained 73.3% of variance. Genotype was responsible for 4.5%–25.3% of the variance in the remaining traits. The genotype-by-environment interaction explained 2.0%–18.8% of variance in the examined traits. The additive main effects and multiplicative interaction model (AMMI) revealed that genotype 13CS0787-15 was potentially most suited for cultivation in the temperate climate of north-eastern Poland, Central Europe. This genotype was characterized by the highest seed yields and straw yields, as well as the greatest yield stability.
The Use of Appropriate Cultivar of Basil (Ocimum basilicum) Can Increase Water Use Efficiency under Water Stress
Authors: Kalamartzis Iakovos , Dordas Christos , Georgiou Pantazis , Menexes George
Published: January 2020

Drought is one of the major yield constraints of crop productivity for many crops. In addition, nowadays, climate change creates new challenges for crop adaptation in stressful environments. The objective of the present study was to determine the effect of water stress on five cultivars of basil (Mrs Burns, Cinnamon, Sweet, Red Rubin, Thai) and whether water use efficiency (WUE) can be increased by using the appropriate cultivar. Water stress affected the fresh and dry weight and also the partitioning of dry matter to leaves, flowers, and stems. Also, there are cultivars, such as Mrs Burns and Sweet, which were not affected by the limited amount of water and continued to produce a high amount of dry matter and also showed high essential oil yield. Essential oil content was not affected by the irrigation; however, essential oil yield was affected by the irrigation, and the highest values were found at Mrs Burns. The water use efficiency was affected by the cultivar and irrigation level, and the highest was found at Mrs Burns. The results show that using appropriate cultivars basil can achieve higher WUE and allow saving water resources and utilizing fields in areas with limited water resources for irrigation.
Physiological Beneficial Effect of Rhizophagus intraradices Inoculation on Tomato Plant Yield under Water Deficit Conditions
Authors: Fracasso Alessandra , Telò Luca , Lanfranco Luisa , Bonfante Paola , Amaducci Stefano
Published: January 2020

Increasing drought, under current climate change scenarios, will reduce the sustainability of tomato cultivation in the Mediterranean region. The present study evaluates the effect of Rhizophagus intraradices inoculation on tomato plant physiology and yield in response to progressive water deficit conditions. Two commercial products (Prod1 and Prod2) containing only R. intraradices were tested at two different concentrations (1% and 5% of the substrate volume) using three methods of inoculation: (a) mixed to substrate, (b) dissolved in water, (c) spread on seedlings root blocks before transplant. The highest mycorrhization of root fragments (F%) was found with Prod2 at 1% w/w at 40 days after sowing (DAS); this product was therefore used in a second experiment to inoculate tomato plants and test their physiological response to progressive water deficit induced withholding irrigation. Phenology, plant height, stem diameter, chlorophyll content and fluorescence, whole canopy gas exchange, biomass production and partitioning and phosphorus content were investigated in inoculated and not inoculated tomato plants under well-watered and water stressed conditions. Vegetative period and plant height were shorter in inoculated than in control plants; moreover, inoculation with R. intraradices increased fruit production by enhancing chlorophyll content under water stress condition, PS2 efficiency, ETR, Fv/Fm, net photosynthetic rate and whole canopy WUE.

The aim of this study was to investigate the blood concentrations of L-arginine, asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and L-homoarginine, which are regulators of nitric oxide (NO) synthesis, in single, twin, and triplet pregnancies in ewes undergoing either a dietary energy restriction or receiving 100% of their energy requirements. From day 24 to 100 of pregnancy, the ewes were fed ryegrass hay and two different iso-proteic concentrates fulfilling either 100% of ewes’ energy requirements (control group; n = 30, 14 singleton pregnancies, 12 twin pregnancies, and 4 triplet pregnancies) or only 45% (feed-restricted group; n = 29; 11 singleton pregnancies, 15 twin pregnancies, and 3 triplet pregnancies). Blood samples were collected monthly to measure, by capillary electrophoresis, the circulating concentrations of arginine, ADMA, homoarginine, SDMA, and of other amino acids not involved in NO synthesis to rule out possible direct effects of diet restriction on their concentrations. No differences between groups were observed in the circulating concentrations of most of the amino acids investigated. L-homoarginine increased markedly in both groups during pregnancy (p < 0.001). SDMA (p < 0.01), L-arginine, and ADMA concentrations were higher in feed-restricted ewes than in controls. The L-arginine/ADMA ratio, an indicator of NO production by NOS, decreased towards term without differences between groups. The ADMA/SDMA ratio, an index of the ADMA degrading enzyme activity, was higher in controls than in feed-restricted ewes (p < 0.001). Obtained results show that circulating concentrations of L-arginine, of its metabolites, and the ratio between NO synthesis boosters and inhibitors are altered in energy-restricted ewes, and that these alterations are more marked in ewes carrying multiple fetuses.

Published: January 2020

Free faecal liquid (FFL) is a condition in horses where faeces are voided in one solid and one liquid phase. The liquid phase contaminates the tail, hindlegs and area around the anus of the horse, resulting in management problems and potentially contributing to impaired equine welfare. The underlying causes are not known, but anecdotal suggestions include feeding wrapped forages or other feed- or management-related factors. Individual horse factors may also be associated with the presence of FFL. This study, therefore, aimed to characterize horses showing FFL particularly when fed wrapped forages, and to map the management and feeding strategies of these horses. Data were retrieved by a web-based survey, including 339 horses with FFL. A large variety of different breeds, ages, disciplines, coat colours, housing systems and feeding strategies were represented among the horses in the study, meaning that any type of horse could be affected. Respondents were asked to indicate if their horse had diminished signs of FFL with different changes in forage feeding. Fifty-eight percent (n = 197) of the horse owners reported diminished signs of FFL in their horses when changing from wrapped forages to hay; 46 (n = 156) of the horse owners reported diminished signs of FFL in their horses when changing from wrapped forages to pasture; 17% (n = 58) reported diminished signs of FFL when changing from any type of forage batch to any other forage. This indicated that feeding strategy may be of importance, but cannot solely explain the presence of FFL. The results also showed that the horses in this study had a comparably high incidence of previous colic (23%, n = 78) compared to published data from other horse populations. In conclusion, the results showed that FFL may affect a large variety of horse types and that further studies should include detailed data on individual horse factors including gastrointestinal diseases as well as feeding strategies, in order to increase the chance of finding causes of FFL.

Published: January 2020

The article presents the results of estimates of thermodynamic parameters (oxygen balance, pressure, temperature, gaseous products produced in the reaction, specific energy, and the combustion heat) for 11 pyrotechnic mixtures and the final product—gas generator prototype (RSP), which can be used in mines for producing blocks. In addition, formal and legal considerations have been presented, as well as the results of gas generators in Polish mines. In order to compare the effects induced by using a detonating cord and a gas generator prototype, a test was carried out in granite quarries involving the measurement, at the same points, of vibration and the air blast. As a result of the tests, limitations and possibilities of using gas generators were indicated.

Published: January 2020

At the moment, many engineer-to-order manufacturers are under pressure, the overcapacity in many sectors erodes prices and many companies, especially in Europe have gone into recent years in bankruptcy. Due to the increasing competition as well as the new customer requirements, the internal processes of an ETO company play an essential role in order to achieve a unique selling proposition (USP). Therefore this paper exposes how the production planning and control of an engineer-to-order manufacturer can be designed in order to increase its OTD (order-to-delivery) rate as well as decrease the WIP (work-in-progress) and the production lead times. To prove the optimized planning logic, it was applied in a simulation case study and based on the results; the conclusions about its potential are derived.

Published: January 2020

The aim of this paper is to propose the 2-tuple spherical fuzzy linguistic aggregation operators and a decision-making approach to deal with uncertainties in the form of 2-tuple spherical fuzzy linguistic sets. 2-tuple spherical fuzzy linguistic operators have more flexibility than general fuzzy set. We proposed a numbers of aggregation operators, namely 2-tuple spherical fuzzy linguistic weighted average, 2-tuple spherical fuzzy linguistic ordered weighted average, 2-tuple spherical fuzzy linguistic hybrid average, 2-tuple spherical fuzzy linguistic weighted geometric, 2-tuple spherical fuzzy linguistic ordered geometric, and 2-tuple spherical fuzzy linguistic hybrid geometric operators. The distinguishing feature of these proposed operators is studied. At that point, we have used these operators to design a model to deal with multiple attribute decision-making issues under the 2-tuple spherical fuzzy linguistic information. Then, a practical application for best company selection for feeds is given to prove the introduced technique and to show its practicability and effectiveness. Besides this, a systematic comparison analysis with other existent methods is conducted to reveal the advantage of our method. Results indicate that the proposed method is suitable and effective for decision making problems.

Published: January 2020

For the effective detection of acoustic emission (AE) impulses against a noisy background, the correct assessment of AE parameters, and an increase in defect location accuracy during data processing are needed. For these goals, it is necessary to consider the waveform of the AE impulse. The results of numerous studies have shown that the waveforms of AE impulses mainly depend on the properties of the waveguide, the path along which the signal propagates from the source to the sensor. In this paper, the analytical method for modeling of AE signals is considered. This model allows one to obtain model signals that have the same spectrum and waveform as real signals. Based on the obtained results, the attenuation parameters of the AE waves for various characteristics of the waveguide are obtained and the probability of defect detection at various distances between the AE source and sensor utilized for evaluation.
Recovery and Transport of Industrial Waste Heat for Their Use in Urban District Heating and Cooling Networks Using Absorption Systems
Authors: Atienza-Márquez Antonio , Bruno Joan Carles , Coronas Alberto
Published: January 2020

The use of industrial excess heat in district heating networks is very attractive. The main issue is the transport of the heat from the point of generation to the local distribution network, in a way similar to the structure of electricity transport and distribution networks. Absorption systems have been proposed to transport and distribute waste heat using two absorption stations. In one of them (step-up station), industrial heat at a low temperature is pumped to a higher temperature to facilitate its transport and at the same time increase the temperature difference between the supply and return streams, in this way reducing the hot water mass flow rate circulating through the heat transport network. Heat is then used in a second absorption system (step-down station) to provide heat to a low temperature local district network. In this paper, several absorption system configurations are analyzed for both stations. A detailed thermodynamic analysis of each configuration is performed using selected energy performance indicators to calculate its global performance. The implementation of these kind of systems could enable the use of waste heat to produce heating and cooling for smart communities located a few dozens of kilometers away from industrial sites.

Published: January 2020

A numerical study of the fire whirl formation under symmetrical and asymmetrical entraining configuration is presented. This work aims to assess the effect of eddy-generation configuration on the evolution of the intriguing phenomenon coupled with both flow dynamics and combustion. The numerical framework implements large-eddy simulation, detailed chemistry to capture the sophisticated turbulence-chemistry interaction under reasonable computational cost. It also adopts liquid-based clean fuel with fixed injection rate and uniformed discretisation scheme to eliminate potential interference introduced by various aspects of uncertainties. The result reveals that the nascent fire whirl formulates significantly rapidly under the symmetrical two-slit configuration, with extended flame height and constrained vortex structure, compared with the asymmetrical baseline. However, its revolution orbit gradually diverges from domain centreline and eventually stabilises with a large radius of rotation, whereas the revolution pattern of that from the baseline case is relatively unchanged from the inception of nascent fire whirl. Through the analysis, the observed difference in evaluation pathway could be explained using the concept of circular motion with constant centripetal force. This methodology showcases its feasibility to reveal and visualise the fundamental insight and facilitate profound understanding of the flaming behaviour to benefit both research and industrial sectors.

Published: January 2020

In this paper, a novel combined heat and power (CHP) system is proposed in which the waste heat from a supercritical CO2 recompression Brayton cycle (sCO2) is recovered by a LiBr-H2O absorption heat pump (AHP). Thermodynamic and exergoeconomic models are established on the basis of the mass, energy, and cost balance equations. The proposed sCO2/LiBr-H2O AHP system is examined and compared with a stand-alone sCO2 system, a sCO2/DH system (sCO2/direct heating system), and a sCO2/ammonia-water AHP system from the viewpoints of energy, exergy, and exergoeconomics. Parametric studies are performed to reveal the influences of decision variables on the performances of these systems, and the particle swarm optimization (PSO) algorithm is utilized to optimize the system performances. Results show that the sCO2/LiBr-H2O AHP system can obtain an improvement of 13.39% in exergy efficiency and a reduction of 8.66% in total product unit cost compared with the stand-alone sCO2 system. In addition, the sCO2/LiBr-H2O AHP system performs better than sCO2/DH system and sCO2/ammonia-water AHP system do, indicating that the LiBr-H2O AHP is a preferable bottoming cycle for heat production. The detailed parametric analysis, optimization, and comparison results may provide some references in the design and operation of sCO2/AHP system to save energy consumption and provide considerable economic benefits.
Advanced Automatic Welding System for Offshore Pipeline System with Seam Tracking Function
Authors: Park Jin-Hyeong , Moon Hyeong-Soon
Published: January 2020

Automatic welding technology is a solution to increase welding productivity and improve welding quality in offshore pipe welding. To increase welding productivity, it is necessary to save time during the assembly/disassembly of the guide track from the welding carriage and pipe to move the next station. The guide track consists of a pneumatic system that does not separate the welding carriage, and two welding carriages operate on a half-pipe joint to increase productivity. These welding carriages automatically operate under the controller command. An automatic welding system consists of a DC motor module, a step motor module, a welding control module, a welding monitoring module, and a central control module. The control systems incorporate control modules and transmit commands to each module for an automatic welding system. In order to minimize the inevitable misalignment between the centerline of the welding seam and the welding torch for each welding pass, a moving average algorithm for seam tracking is proposed, which was proven to be suitable for the root pass, filling pass, and cap pass. Welding experiments were also carried out to verify the validity of the weld seam tracking system.
Active Switching of Extremely High-Q Fano Resonances Using Vanadium Oxide-Implanted Terahertz Metamaterials

Published: January 2020

In this paper, we demonstrate an active switching of extremely high Q-factor Fano resonances using vanadium oxide (VO2)-implanted THz asymmetric double C-shaped metamaterial (MM) structures. The simulation results indicate the highly temperature-sensitive nature of the double Fano resonances that can be switched at very low external thermal pumping (68 °C), which is only slightly higher than room temperature. We employ the surface current and electric field distributions of the structure to analyze the physical mechanism of the observed switching behavior in the thermally excited Fano MMs. More importantly, by optimizing the asymmetric parameter (offset length), the linewidth of the Fano resonance can reach only 0.015 THz and the Q-factor is as high as 98, which is one order of magnitude higher than that of the traditional MMs. The findings of this work would enable a thermally-induced high-Q Fano resonance MMs for ultra-sensitive sensors, modulators, low threshold switching in metadevices.
Natural Kenaf Fiber and LC3 Binder for Sustainable Fiber-Reinforced Cementitious Composite: A Review
Authors: Baghban Mohammad Hajmohammadian , Mahjoub Reza
Published: January 2020

Low impact on the environment and low cost are the key drivers for today’s technology uptake. There are many concerns for cement production in terms of negative environmental impact due to greenhouse gas (GHG) emission, deficiency of raw materials, as well as high energy consumption. Replacement of the cement by appropriate additives known as supplementary cementitious materials (SCMs) could result in reduction in GHG emission. Limestone-calcined clay cement (LC3) is a promising binder in the concrete sector for its improvements to environmental impact, durability, and mechanical properties. On the other hand, the advantages of fiber-reinforced concrete such as improved ductility, versatility, and durability have resulted in increasing demand for this type of concrete and introduction of new standards for considering the mechanical properties of fibers in structural design. Thus, using natural fibers instead of synthetic fibers can be another step toward the sustainability of the concrete industry, which is facing increasing demand for cement-based materials. This review studies the potential of natural Kenaf fiber-reinforced concrete containing LC3 binder as a step toward green cementitious composite. While studies show that energy consumption and GHG emission can be reduced and there is a significant potential to enhance mechanical and durability properties of concrete using this composition, adjustment of the mix design, assessing the long-term performance and standardization, are the next steps for the use of the material in practice.

Deep Fake Image Detection Based on Pairwise Learning
Authors: Hsu Chih-Chung , Zhuang Yi-Xiu , Lee Chia-Yen
Published: January 2020

Generative adversarial networks (GANs) can be used to generate a photo-realistic image from a low-dimension random noise. Such a synthesized (fake) image with inappropriate content can be used on social media networks, which can cause severe problems. With the aim to successfully detect fake images, an effective and efficient image forgery detector is necessary. However, conventional image forgery detectors fail to recognize fake images generated by the GAN-based generator since these images are generated and manipulated from the source image. Therefore, in this paper, we propose a deep learning-based approach for detecting the fake images by using the contrastive loss. First, several state-of-the-art GANs are employed to generate the fake–real image pairs. Next, the reduced DenseNet is developed to a two-streamed network structure to allow pairwise information as the input. Then, the proposed common fake feature network is trained using the pairwise learning to distinguish the features between the fake and real images. Finally, a classification layer is concatenated to the proposed common fake feature network to detect whether the input image is fake or real. The experimental results demonstrated that the proposed method significantly outperformed other state-of-the-art fake image detectors.
