Authors: Nurfiqih Deifa , Hakim Lukman , Muhammad Muhammad
Published: November 2021

Asam lemak merupakan hasil hidrolisa dari minyak sawit, didalam minyak sawit terdapat berbagai macam asam lemak, tetapi didalam perhitungan asam lemak yang digunakan adalah asam palmitate. Selain proses hidrolisa, proses oksidasi juga dapat terjadi karena kenaikan asam lemak bebas. Air dapat menguap pada minyak sawit jika dipanaskan pada suhu 150oC, karena itu pemanasan perlu dilakukan untuk mengurangi pertambahan asam lemak bebas pada CPO dengan proses hidrolisa. Penelitian ini bertujuan untuk membandingkan antara lama penyimpanan, suhu pemanasan dan persentase air didalam minyak kelapa sawit. Metode yang digunakan yaitu persiapan bahan baku dan tahap pengujian. Untuk hasil dalam analisa asam lemak bebas dan kadar air yang paling bagus yaitu waktu penyimpanan selama 8 jam pada suhu 60oC dengan nilai asam lemak bebas (ALB) yaitu 2,5% dan kadar airnya dengan nilai 0,38%. Hasil analisa yang dihasilkan persentase air sangat berpengaruh besar dalam kenaikan asam lemak bebas (ALB) dibandingkan dengan suhu pemanasan dalam minyak kelapa sawit. Diharapkan untuk penelitian selanjutnya dapat dilakukan variasi waktu pemanasan agar memperoleh hasil yang sesuai dengan standar mutu.

Published: November 2021

None of the known native actinorhizal species in Turkey, Alnus glutinosa and A. orientalis (Betulaceae), Datisca cannabina (Datiscaceae), Elaeagnus angustifolia and Hippophae rhamnoides (Elaeagnaceae), and the widely-planted exotic Casuarina cunninghamiana (Casuarinaceae), have confirmed records of actinorhizae in Turkey. This study determined the capacity of representative actinorhizal plants in Turkey to form nodules, cluster roots and ectomycorrhizal roots in a typical central Anatolian soil with and without amendment of soil and nodule extracts, as well as in soil from Adana and Izmir. Nodulation was confirmed experimentally for E. angustifolia and C. cunninghamiana in Niğde soil (the latter only with addition Adana or Izmir soil), but only observationally for A. glutinosa during sample collection in Rize. Cluster roots developed strongly in C. cunninghamiana, and likewise ectomycorrhizal roots in Allocasuarina verticillata (included as a reference species) but only to a lesser extent in C. cunninghamiana. The nodulation status of the natives, D. cannabina and H. rhamnoides, remains to be investigated.

Indonesia's coal reserve is abundant with its lower price and widely distributed than oil and natural gas. However, the coal emits high carbon dioxide gas (CO2) and sulfur compounds (H2S, SOx) to the environment during utilization. Plasma gasification can overcome those lacks using the external electric energy through a plasma torch. The chemical properties of coal have impacts on the energy content and environmental benchmarking. Using steam as a gasifying agent should be adequate to produce H2 and CO syngas. A research has been carried out to analyze and understand the benefit of using different gasifying agent for maximizing the H2 production and minimizing the environmental impact. Pure Steam (PS) gasifying agent to coal ratio of 0.4 has shown 43.76% H2 composition in syngas and cold gasification efficiency (CGE) with 37.71%. The PS to coal ratio of 0.2 has a significant carbon conversion efficiency of 4.75% and the PS to coal ratio of 0.6 has a gross energy potential of 86.5 kW. Using such the PS is significantly better than the mixture of steam oxygen (SO) as the gasifying agent since it needs to have a greater SO flow rate to have the SO to coal ratio of 1.00.

Bijih nikel laterit merupakan mineral yang mengandung senyawa oksida besi-nikel. Teknologi pengolahan nikel laterit secara umum ada 3 metode yaitu hidrometalurgi, pirometalurgi dan reduksi selektif. Hidrometalurgi merupakan metode yang menggunakan pelindian dan larutan seperti asam untuk mengekstraksi nikel laterit. Metode dengan pelindian asam yang bertekanan adalah metode yang paling optimal untuk mendapatkan nikel dengan grade dan recovery tertinggi. Akan tetapi metode ini memiliki dampak pencemaran lingkungan akibat hasil proses pelindian dan waktu yang lama. Metode yang kedua, yaitu pirometalurgi menggunakan temperatur tinggi sampai 1600°C sehingga membutuhkan banyak energi seperti proses blast furnace. Metode dengan rotary kiln-electric furnace merupakan metode optimal dalam pengembangan nikel laterit. Akan tetapi kekurangannya yaitu tanpa pemisahan pengotor, energi yang besar, serta masih ada permasalahan teknis seperti adanya material yang mengalami melt partial. Metode yang ketiga yaitu reduksi selektif merupakan proses pemisahan dengan menyeleksi terbentuknya besi oksida sehingga mendapatkan kadar nikel yang tinggi tanpa energi yang tinggi. Hal ini disebabkan adanya penambahan aditif untuk menghambat terbentuknya besi dan menurunkan temperatur reduksi. Metode ini sebagai alternatif pengolahan bijih nikel laterit jenis limonit dan saprolit menjadi konsentrat nikel dengan kadar nikel di atas 5 %.

Published: December 2021

The rate of removal of internal combustion (IC) engine thermostat when engines are imported to Ghana and other part of African continent is alarming. Such phenomenon calls for an experiment to compare the performance of IC engines imported here in Ghana running with and without engine thermostat. The analysis was done by determine engine performance characteristic such as engine torque, indicated power (Ip), brake power (bp), frictional power (fp), fuel consumption, exhaust gas temperature (EGT) as well as exhaust emission at engine speed of 1500 rpm for engine running with thermostat (WT) and without thermostat (WOT). Descriptive statistics and analysis of variance (ANOVA) were done using GenStat software (VSN International, 2021). Statistical significance was carried out at p≤0.05. The best fuel mean value of 103 ml was recorded for engine condition WT at EGT of 283.2 °C while fuel consumed for engine condition WOT was 170 ml at EGT of 155.4 °C. The recorded mean exhaust emission gases for Ex, O2, CO, H2S were 13.2%, 16.2%, 1000 ppm and 35.2 ppm and 0%, 18.38%, 393.2 ppm and 0.4 ppm for engine condition WOT and WT respectively. There was significant difference (p≤0.05) in mean values of EGT, Fuel consumption and exhaust emissions for engine condition WOT with the exception of O2. The removal of engine thermostat affect engine working temperature which result in incomplete combustion, high fuel consumption and high exhaust emissions.

Published: November 2021

Many different disciplines use deep Learning algorithms for various purposes. In recent years, object detection by deep learning from aerial or terrestrial images has become a popular research area. In this study, object detection application was performed by training the YOLOv2 and YOLOv3 algorithms in the Google Colaboratory cloud service with the help of Python software language with the DOTA dataset consisting of aerial photographs. 43 aerial photographs containing 9 class objects were used for evaluation. Accuracy analyzes of these two algorithms were made according to Recall, Precision and F-score for 9 classes, and the results were compared accordingly. YOLOv2 gave better results in 5 out of 9 classes, while YOLOv3 gave better results in recognizing small objects. While YOLOv2 can detect objects in an average photograph in 43 seconds, YOLOv3 has achieved superior performance in terms of time by detecting objects in an average of 2.5 seconds.
Development of Modeler for Automated Mapping of Land Surface Temperature Using GIS and LANDSAT-8 Satellite Imagery
Authors: Sutariya Sachin , Ankur Hirapara , Tiwari Mukesh
Published: November 2021

Land surface temperature (LST) can be described as the temperature of the earth’s surface and it is most important parameters in climate change, evapotranspiration, urban climate, vegetation monitoring and environmental studies. LST, calculated from remote sensing data, is used in many areas of science such as; hydrology, agriculture, forestry, oceanography etc. The main objective of this study was to develop a model making the LST retrieval process quite simple and automated. This model developed using the ArcGIS Desktop 10.3.1 with the Model Building. Without the model, the process of retrieving LST is very long, and it is susceptible to many mistakes. In this model when user inputs required bands (4,5 and 10) of Landsat-8 data then the model calculate automatically LST and display output. The model first makes the conversions to top of atmosphere (TOA) spectral radiance. Then NDVI is calculated based on band 4 and 5 (NIR and RED) reflectance. Then using the TOA and NDVI model calculates brightness temperature (BT) and Proportion of Vegetation respectively. After that it calculate Land Surface Emissivity with the help of NDVI and Proportion of Vegetation and finally, the model calculates land surface temperatures in degrees Celsius. The findings highlight the capabilities of GIS modelers for such spatial estimation. The developed model can be helpful to field engineers and researchers for using Landsat-8 images for direct estimation of LST, to be used for different other studies to derive LST based products.
Regulation of Mineral Resource Activities in Antarctica
Authors: Ergüven Nasıh Sarp , Ozsoy Burcu , Yirmibeşoğlu Sinan , Oktar Özgün
Published: November 2021

Mineral resource activities in Antarctica were brought to the agenda at the 6th Antarctic Treaty Consultative Meeting (ATCM) held in Tokyo for the first time in 1970. The Convention on the Regulation of Antarctic Mineral Resource Activities (CRAMRA), which regulates the issue in detail, could not enter into force after France and Australia decided not to sign the Convention. The Protocol on Environmental Protection to the Antarctic Treaty (PEPAT) was signed after the Special ATCMs that took place in Madrid in 1991 to review the Antarctic Treaty. The Protocol entered into force on 14 January 1998, after the ratification of all Consultative Parties. PEPAT, which does not modify the Antarctic Treaty in any way, is among the legal documents within the Antarctic Treaty System (ATS) as its annex. Unlike CRAMRA, with the provision of PEPAT Article 7, mineral resource activities are completely prohibited. The only exception to the related prohibition is mineral resource activities for scientific research. This does not mean that the mentioned activities will be carried out in an unlimited way. These activities are subject to PEPAT and Annex 1 Environmental Impact Assessment. Continuity of the absolute prohibition of mineral resource activities is a significant issue. Accordingly, in accordance with Article 25/1 of PEPAT, provisions of the PEPAT may be modified or amended by the unanimous agreement of the Consultative Parties including Article 7. Apart from this, in the ongoing paragraph of the same article, after the expiration of 50 years from the date of entry into force of PEPAT, this period corresponds to 2048, a conference will be held to review the functioning of PEPAT with the notification of any of the Consultative Parties. It was envisaged that the proposed amendments to the PEPAT at the Review Conference would be adopted by a majority of the Parties, including 3/4 of the States which are Consultative Parties at the time of PEPAT's entry into force (1998), including Article 7, which prohibits mineral resource activities. When signed, PEPAT, which is considered to be difficult to enter into force since all of the Consultative Parties' approval has to be given, took effect in line with the emergence of the common interest in this direction. This shows the Consultative Parties' commitment to the protection of Antarctica and especially the prohibition of mineral resource activities. The determination in question was once again expressed by the Declaration published after the 32nd ATCM and the Resolution adopted in the 39th ATCM, although they were not legally binding. Especially in the Resolution, the emphasis on both the continuity of the prohibition on mineral resource activities and the incorrect belief in the media that PEPAT will be expired in 2048 is noteworthy.
Transfer Factors of Natural Radionuclides from Soil to Medicinal Plants used by Local People in Eastern Anatolia, Turkey
Authors: Bilgici Cengiz (eker) Gülçin , Çağlar İlyas
Published: November 2021

Medicinal plants are very useful plants for humans with the various molecules and vitamins they contain. Most of the plants that grow spontaneously in nature were taken into agricultural production practices after their healing properties were discovered. The use of pure active ingredients obtained from plants is quite common. These effective compounds are also used by the pharmaceutical industry in the preparation of modern drug formulations. However, possible high levels of natural radionuclides in medicinal plants, particularly 226Ra, 232Th and 40K, have upraised anxieties regarding radiological risks from plant consumption. In this study, the natural radionuclide activity concentrations of 8 commonly used medicinal plants in the Eastern Anatolia Region of Turkey were determined by gamma spectrometric method using NaI(Tl) detector. Mean transfer factor (TF) values from soil to plant were found to be 0.59, 0.88 and 1.52 for 226Ra, 232Th and 40K, respectively.
The Character of Soil Temperature Regime over Turkey
Authors: Tekkanat İlyas Sadık , Öztürk Beyhan
Published: November 2021

This paper presents the spatial and temporal characteristics of Turkish soil temperature regimes. Basic data consists of the monthly soil temperature averages from 153 stations at depths of 5, 10, 20, 50 and 100 cm for 44 years (1975-2018) record length. The soil temperature regime of Turkey has been analyzed based on both classical climatic regime approach (monthly average soil temperature change) and Soil Taxonomy. As expected, The annual course of soil temperatures differs between the coastal and inland areas of Turkey and in the western and eastern half. Latitude and continentality shapes the soil temperature regime in the eastern half of Turkey while elevation shapes the soil temperature regime in the western half of Turkey. The frost is seen in the eastern half of Turkey in January and February, except for coastal areas. Morever, the frost period goes up to 4 months (November-February) in northeastern Anatolia. Frost reaches up to 90 cm in this area. The high soil temperatures adversely affecting plant life (35 °C and above) is seen in the South-East Anatolia Region and Çukurova region in Turkey in July and August. These high temperatures are effective up to 80 cm in the region. The majority of Turkey has thermic soil or mesic soil. Considering long-term averages (1975-2018), there are four main soil temperature regimes in Turkey as frigid, thermic, mesic, hyperthermic. The eastern Mediterranean coastline and the southwestern Anatolian coastline are hyperthermic soil temperature regime character and the northeast Anatolia (Ardahan surroundings) show a frigid temperature regime character. Percentages of thermic and hyperthermic soil temperature regime have been increasing in the last 10 years. The increase is probably due to the above normal average air temperatures from July to December and the breaking of air temperature records in the last 10 years.

Published: November 2021

Na hipótese de Kuznets (1955), a associação entre desigualdade e crescimento econômico se caracteriza por correlação positiva (concentração de renda), nos estágios iniciais do desenvolvimento econômico, e correlação negativa (desconcentração de renda), nos estágios finais. Existe uma vasta agenda tentando verificar tal hipótese, porém os resultados são inconclusivos. Assim, este trabalho buscou tanto verificar a hipótese de Kuznets nos municípios mineiros entre os anos de 2000 e 2010, quanto identificar se a desigualdade municipal responde por heterogeneidades municipais não observáveis. Utilizando dados em painel e adotando a renda média domiciliar per capita e o coeficiente de Gini, estimou-se dois modelos: quadrático e cúbico. As evidências permitiram tanto a não validação da hipótese de Kuznets quanto a verificação de heterogeneidades municipais não observáveis. Em geral, os resultados realçam o papel das políticas públicas centradas em transferências de renda e fornecimento de serviços públicos de qualidade enquanto mecanismos de promoção da equidade.

Authors: Ewim Daniel , Opateye Johnson
Published: November 2021

Assessment is essential in the learning and teaching process. In chemistry teaching, deployment of assessment to ascertain the levels of assimilation and understanding of concepts being taught in the class is considered central in the learning process. Through the assessment for learning, teachers check students’ understanding and get valuable feedback data on students’ learning. This data is used to modify and improve instruction. Educational world order has drastically changed due to the emergency of COVID-19 that influenced the modes of educational delivery at such a time like this. The only option to deliver learning and assessment processes is the deployment of technology to be able to meet the demands of pandemic and its associational protocols. Information and Communication Technology (ICT) affects every facet of life including education. This paper, therefore, examined the nature of assessment of chemistry learning and the ICT tools that are required to drive the assessment procedures. In addition, it discussed the ICT feedback mechanisms in assessing the learning process in chemistry. Consequently, the paper suggested that relevant ICT tools should be used by chemistry teachers to monitor students’ academic progress and foster ICT-driven effective feedback for assessment of chemistry learning. As a result, ICT should be deployed to assist chemistry teachers in carrying out assessment for learning to diagnose learners’ understanding and difficulties during the process of instruction.

Violation of the law at sea is one indicator to measure the security level of a country. To maintain security stability at sea in Indonesia, the Government needs to forecast the number of violations of the law at sea to determine the next policy. Forecasting is a picture of events that will occur in the future. The method used to predict law violations in the Indonesian seas is the Triple Exponential Smoothing (TES) Hold-Winters, the TES method is a pretty good forecasting method for long-term, medium-term and short-term forecasting. The processed data is data on law violations in the Indonesian seas from 1996 to 2019 from the Indonesian Maritime Security Agency. The results obtained from this study are the results of the analysis of the level of accuracy of the MAD, MSE, MAPE, MSE and RMSE data to find the smallest error value.

A dolgozat egy amerikai performanszművész és politikai aktivista, Billy tiszteletes példáján keresztül egy olyan performatív működésmódot elemez, amelyet rituális, teátrális és politikai szintek összjátéka hoz létre. A tanulmány két párhuzamos példával világítja meg a Billy performanszainak logikáját: az egyik a középkori Corpus Christi hagyomány misztériumjátékainak rituális teatralitása, a másik pedig a performatív munka, amellyel a fogyasztók fenntartanak egy brandet, azáltal, hogy általa a felkínált szerepeket magukra öltik. Az érvelés Weimann locus és platea definícióit Victor Turner segítségével igyekszik árnyalni, hogy a mundus terminus bevezetésével (a két weimanni terminust kiegészítendő), rámutasson a teatralitásnak egy olyan fajtájára, amely a közönség választása vagy hite nyomán jön létre, és alakítja a társadalmi valóságot.
The Role of Gendered Entitlement in Understanding Inequality in the Bedroom
Authors: Klein Verena , Conley Terri
Published: December 2021

Five studies (using U.S. samples) examined whether men’s higher entitlement contributes to a sexual pleasure gap that disadvantages women. Participants indicated that men receive more sexual pleasure from their partners, whereas women provide more pleasure (Study 1a). Participants believed that men have more of a right to experience orgasm in both hook-up and relationship encounters and attributed higher negative affect to the male target than to the female target when the target did not experience an orgasm in a sexual scenario (Study 1b). In concert with the idea that pleasure is a privilege that men are perceived as being more entitled to, participants preferred men’s orgasm when forced to choose between the male and the female partner in an orgasm allocation task (Study 1c) and in an experiment (Study 2). Study 3 examined why people believe that men are more entitled to pleasure than women. Men’s higher sense of entitlement as an obstacle to gender equality in sexuality is discussed.

Published: December 2021

Background. COVID-19 research has relied heavily on convenience-based samples, which—though often necessary—are susceptible to important sampling biases. We begin with a theoretical overview and introduction to the dynamics that underlie sampling bias. We then empirically examine sampling bias in online COVID-19 surveys and evaluate the degree to which common statistical adjustments for demographic covariates successfully attenuate such bias. Methods. We analysed responses to identical questions from three convenience and three largely representative samples (total N = 13,731) collected online in Canada within the International COVID-19 Awareness and Responses Evaluation Study (www.icarestudy.com). We compared samples on 11 behavioural and psychological outcomes (e.g., adherence to COVID-19 prevention measures, vaccine intentions) across three time points and employed multiverse-style analyses to examine how 512 combinations of demographic covariates (e.g., sex, age, education, income, ethnicity) impacted sampling discrepancies on these outcomes.Results. Significant discrepancies emerged between samples on 73% of outcomes. Participants in the convenience samples held more positive thoughts towards and engaged in more COVID-19 prevention behaviours. Covariates attenuated sampling differences in only 55% of cases and increased differences in 45%. No covariate performed reliably well. Conclusion. Our results suggest that online convenience samples may display more positive dispositions towards COVID-19 prevention behaviours being studied than would samples drawn using more representative means. Adjusting results for demographic covariates frequently increased rather than decreased bias, suggesting that researchers should be cautious when interpreting adjusted findings. Using multiverse-style analyses as extended sensitivity analyses is recommended.

Published: November 2021

Retention and recruitment of clinical faculty is crucial for the success of quality veterinary education. Clinical faculty in busy teaching hospital environments have the potential to experience significant burnout, though few studies have focused on identifying stressors in this group. The objective of this study was to measure burnout and professional fulfillment in clinical faculty using a recently validated instrument, the Stanford Professional Fulfillment Index (PFI). The survey was distributed to faculty in July 2020, a time that coincided with the COVID-19 pandemic. The survey was completed by 80% (52/65) of survey recipients. Scores for Overall Burnout were significantly higher (p = .027) and Professional Fulfillment scores significantly lower (p < .001) for veterinary faculty when compared with a reference group of academic physicians; 61.7% (29/47) of the faculty met the criteria for burnout, and 20.4% (10/49) met the criteria for professional fulfillment. Overall Burnout and Professional Fulfillment scores were not affected by faculty rank or gender, although interpersonal disengagement was greater in faculty who had worked > 6 years at the institution (p = .032). Responses indicated that faculty valued their work and their patients but faced an excessive workload and lacked autonomy to make changes. Faculty proposed improving efficiency, increasing staffing, and distributing work to technical staff. The PFI is a brief, no-cost instrument validated for measuring burnout and fulfillment in health care workers that can be used to assess well-being among veterinary faculty. Involving faculty in suggesting interventions may yield a variety of creative and actionable options.

Introduction
Authors: Barthelemy Martine , Jaume Lucien
Published: December 2021

Contrairement à la démocratie américaine, dont Tocqueville vantait au début du XIXe siècle la puissante vie associative, la République française a longtemps paru méfiante à l’égard de tout ce qui pouvait rappeler les « corps intermédiaires » de l’Ancien Régime. Ces réticences n’ont certes pas empêché la France de connaître, durant tout le XIXe siècle et jusqu’à nos jours, le développement d’innombrables groupements en tout genre. Les pratiques semblent ainsi contredire les représentations, marquées par une culture politique de l’intérêt particulier face à l’intérêt général, du citoyen isolé devant l’Etat maître du social.
The lyric oeuvre of Afanasy Fet and Chinese idyllic poems
Authors: Lu Zh.
Published: November 2021

There are compelling similarities between Afanasy Fet’s lyric poetry and classical Chinese lyric poetry. This connection is traced in the article with speciﬁc examples. Fet, carried away by the ideas of Schopenhauer, argued that thepoetic feeling lives in every person and can be called the sixth and highest feeling. In classical Chinese poetry, the Confucian concept of ‘the sense of things,’ the Taoist formula ‘words and forms’ and the idea of the unity of man and nature played an important role. With characteristic ﬁxation of subtle changes of light and shadow, with the transmission of flushed feelings, Fet’s oeuvre reminds the readers of the ancient Chinese lyric poetry. Like classic Chinese texts, Fet’s poems are textbooks where the idea of the unity of man and nature is developed. In both Chinese poetry and Fet’s works, human life goes into natural life, gaining eternity in the nature. As a result, although Fet was not familiar with Chinese culture, the intuitions that fed his work surprisingly coincided with pictorial techniques as a way of conveying emotion in classical Chinese poetry, separated from him by many centuries.

Published: November 2021

The collection prepared by IMLI RAN contains letters of the eminent specialist in local history N. Antsiferov and focuses on the biography of this St. Petersburg Imperial University alumnus, who, despite many arrests by the Soviet regime on trumped-up charges, incarceration in prisons and guarded camps and exile, preserved his inner freedom and, therefore, his scholarly potential. The book details the political context that brought about the outrageous persecution of this highly skilled and staunchly apolitical scholar aswell as the abrupt clearance of charges. Also included is a summary of his scholarly output in literary history, local history and cultural studies. The book lists the scholar’s acquaintances and correspondents, e. g., M. Bakhtin, V. Vernadsky, M. Lozinsky, A. Meyer, K. Chukovsky, B. Eichenbaum, and many other members of the intellectual elite. The book is celebrated as a landmark scholarly publication; highly praised are the text preparation eﬀorts and explanatory notes.
‘A type of a literary Cheka agent’: G. Benn on S. Tretiakov’s Berlin lectures
Authors: Kovalyov N. I.
Published: November 2021

The article examines an incident in the history of Russo-German literary relations — the lectures delivered by a LEF (Leﬅ Front for Arts) leader Sergey Tretiakov in Germany (1930–1931) and their reception by German literary circles. Along with ecstatic feedback from leﬅist writers, Tretiakov’s appearance provoked criticism from a more conservative public. It is to the criticism of the lecture from the viewpoint of ‘art for art’s sake’ that Gottfried Benn devotes his radio broadcast of ‘The New Literary Season’ (1931), subjected to a detailed analysis in this article. Although contesting Tretiakov’s views of the relationship between literature and politics, as well as oﬀering their slightly cartoonish depiction, Benn provides a fairly detailed description of thetheses; it becomes an important source of information about the contents of Tretiakov’s lectures since one of them was never published. Comparing Benn’s rendering of Tretiakov’s ideas with other publications by Tretiakov, the author discovers that Benn presents an accurate summary of Tretiakov’s critical views on Russian classics and the role of a writer in a Socialist society.

Published: November 2021

In conditions of high business competition, IT organizations need to respond quickly to the needs of their users who need resources to support business applications. This is due to the rapid spread of the cloud computing model, in which resources can be deployed independently and on demand. Cloud computing is a source of tools to automate the deployment of resources, so IT organizations do not have to spend so much time doing this process manually. When deploying new applications, moving virtual servers or commissioning new instances due to dynamic applications, the network must respond quickly and provide the required type of connection. There has been a significant breakthrough in software configured networks (SDN / NFV) over the past few years. SDN / NFV organizations need to increase network adaptability by automating the network on cloud computing platforms.However, the new challenges posed by the combination of cloud computing and SDN / NFV, especially in the area of enterprise network security, are still poorly understood. This article is about solving this important problem. The article examines the impact on the mechanisms of protection against network attacks in the corporate network, which uses both technologies, simulates DDoS-attacks on cloud computing systems. It has been shown that SDN / NFV technology can really help protect against DDoS attacks if the security architecture is designed correctly.
