The paper presents results of radiation survey of terrestrial (natural and agrarian) ecosystems in the 30-km zone around the State Scientific Centre "Research Institute of Atomic Reactors" (SSC RIAR, Institute) before the commissioning of the fast neutron reactor MBIR. Due to long-term emissions during the RIAR operation, 137Cs was mainly emitted into the environment. The most part of the radionuclide activity never extends beyond the border of the Institute sanitary protec-tion zone. In 2011 the average density contamination of the soil with 137Cs was 11.16.5 in the sanitary protection zone (0-5 km), 3.12.3 in the observation zone (5-12.5 km), 1.30.4 kBq/m2 in the influence zone (12.5-30 km). The 137Cs/90Sr ratio is maximum in the soil cover in the sanitary protection zone – 24.519.4; it is 8.26.8 in the observation zone and it is close to the level of global fallout – 2.00.5 in the influence zone. More than 90% of 137Cs is deposited in the 0-5 cm soil layer in forest and meadow cenoses and the radionuclide is deposited at a depth of up to 20 cm in a swamp. The highest 137Cs concentration was found in ecosystems components: in vege-tation in the RIAR sanitary protection zone and, to a greater extent, in forest litter. At the initial pe-riod of RIAR operation discharges of process water happened, a piece of land of 0.12 km2 was contaminated with 137Cs, 90Sr and 239,240Pu. Over the past 15 years (2005-2020), the density of soil contamination with 137Cs and 90Sr in RIAR zones of observation and influence has been decaying in accordance with the radioactive decay law. It means that no significant emissions from the In-stitute have been registered. The content of artificial radionuclides in agricultural products and foodstuffs of local production fully meets the established radiological standards and does not have a significant effect on the additional exposure of the population living near RIAR. To assess the impact of the SSC “RIAR" activities on the environment and to assess the radiation safety of the MBIR after putting it in operation, a forecast of 137Cs and 90Sr contamination levels in soils of terrestrial ecosystems within 30-km around the Institute until 2080 was made.

Currently, a specific action on tumor cells with minimal toxicity to healthy tissues is the main re-quirement for radionuclide therapy of cancer. The molecular target of selective antitumor therapy is determined by somatostatin receptors (SSTR) overexpression in various tumors and its metas-tases. Natural somatostatin cannot be used as a vector molecule for radionuclide delivery due to its short half-life in blood (1-3 min). Synthetic peptide somatostatin analogs labeled with thera-peutic radionuclides (radiopeptides) also have high affinity to SSTR and better pharmacokinetics compared to somatostatin and therefore they are of great interest for targeted cancer therapy, al-so called peptide-receptor radionuclide therapy (PRRT). The data about the most important to date somatostatin analogs labeled with In-111, Y-90, Lu-177 radionuclides for therapy of tumors over-expressing SSTR is presented. The results of treatment efficacy and toxicity profile of PRRT, which is administered with various generations of targeting SSTR radiopharmaceuticals, includ-ing the randomized controlled trial NETTER-1, is reviewed. In addition, some strategies for opti-mization of PRRT such as tandem therapy, intra-arterial administration of radiopharmaceuticals, their modification for better pharmacokinetic properties, and the development of new compounds containing alfa-emitting radionuclides or SSTR antagonist analogs are discussed.

Bu çalışmada, Tavşanlı Ovası genelinde yer alan yüzey sularının hidrojeokimyasal özelliklerini ve su kalitesini belirlemek amacıyla Ekim (2018) döneminde 13 farklı lokasyondan su örnekleri alınmış ve fizikokimyasal parametreler (pH, oC, EC ve TDS) yerinde ölçülmüştür. Yüzey sularının hidrojeokimyasal özelliklerinin tanımlanmasında, öncelikle suların iyon içerikleri ile fizikokimyasal özellikleri incelenmiştir. Bunların yanı sıra suların kökenlerinin belirlenmesi amacı ile Schoeller ve Piper (1944) diyagramları kullanılarak değerlendirmeler yapılmıştır. Çalışma alanında yer alan suların içme suyu olarak kullanım özelliklerinin ve kalitesinin değerlendirilmesinde ise ulusal ve uluslararası standartların yanı sıra Su Kalite İndeksi (WQI) yönteminden yararlanılmıştır. Çalışma alanındaki yüzey suları iyon bollukları ile ilişkili olarak Ca-CO3 ve Ca-Mg-HCO3’lü sular fasiyesinde yer almaktadır. Su örneklerinin analiz sonuçları TSE-266 ve WHO (2008) ile belirlenmiş sınır değerler ile kıyaslandığında Sekiören Göletinden alınan örnek hariç diğer tüm su örneklerinin yüksek arsenik konsantrasyonuna (0,0082 - 0,7391 mg/l) sahip olduğu ve bu sebeple içme suyu olarak kullanıma uygun olmadığı sonucuna varılmıştır. Bu sonuçlara göre bölgede yüzeysularının içme suyu olarak kullanılmasının önlenmesi ve alternatif içme suyu kaynaklarının araştırılması gerekmektedir.

Published: June 2022

In this study, effect of aggregate specific gravity, which is directly related to origin of aggregates used in hot mix asphalt on optimum bitumen content, indirect tensile strength and tensile strength ratio of hot mix asphalt, was investigated. Specific gravity (SG) values of one kind of limestone aggregate were calculated according to Turkish Standard (TS), American Society for Testing and Materials (ASTM) and American Association of State Highway and Transportation Officials (AASHTO) standards, separately. Although one kind of limestone aggregate and 50/70 penetration grade bitumen are used in the mixtures, different values were obtained in terms of optimum bitumen content, indirect tensile strength and moisture sensitivity due to differences in the specific gravity values of the aggregates. Optimum bitumen contents were found by using TS, ASTM and AASHTO standards as 5.03%, 4.75% and 4.59%, respectively. According to the cost – benefit analysis, it can be said that changes in aggregate specific gravity values, which were calculated, based on different standards provide economic benefit. Overall, the results indicated that specific gravity values of one kind of limestone aggregate used in hot mix asphalt have significantly affected optimum bitumen content and indirect tensile strength of the mixtures.

PERFORMANCE ANALYSIS AND OPTIMIZATION OF A HELICAL CROSS-FLOW WATER TURBINE
Authors: ÖĞÜÇLÜ Özer
Published: June 2022

In this study, a Computational Fluid Dynamics model is designed to investigate the performance analysis of a helical cross-flow water turbine by using Comsol Multiphysics. In order to predict the main performance characteristics of turbine such as power output and torque, a numerical model is developed which is accurate, fast and quite simple to be used for a simulation. The flow field around turbine is solved with the Rotating Machinery feature in the Comsol CFD Module using a k-ω turbulence model and a steady state formulation. The Navier-Stokes equations are used in the model which are arranged in a rotating frame in the inner domain and in fixed coordinates in the outer domain. The boundary between the inner and the outer domain is a continuity boundary condition that transfers momentum to the fluid in the inner domain. This model also uses the Frozen Rotor study type which speeds up the computation time. Then, to increase the performance of the cross-flow water turbine, a new angular velocity profile is explored with Comsol Optimization Module. Thus, a variable speed turbine control method is developed. Compared to the constant velocity control method, new angular velocity control method yielded a 3% increase in the efficiency of turbine.

Published: June 2022

Beton yüksek basınç dayanımı yanı sıra çok düşük elektriksel iletkenliği sahiptir. Bu çalışmada kendiliğinden yerleşen betonun (KYB) elektriksel özdirenci, iletkenliği ve sıcaklık artışı üzerinde uzun ve kısa çelik liflerin etkisini, lif kombinasyonu (tek ve karma) ve kısa çelik liflerin boyuna (6 ve 13 mm) bağlı olarak belirlemek için dört adet karışım tasarlanmıştır. Bu karışımlar, lifsiz referans, sadece uzun tek lif takviyeli ve uzun lif ile iki farklı boya sahip kısa çelik lif içeren iki adet karma çelik lif takviyeli karışım olmak üzere dört farklı karışım tasarlanmıştır. Tüm çelik lif takviyeli KYB karışımları hacimce toplam %1 lif içermektedir. Karışımların belirlenmesinde EFNARC tarafından önerilen işlenebilirlik testleri (Çökme-yayılma, t500 ve J-halkası yükseklik farkı) dikkate alınmıştır. Karışımlara ait mekanik özellikler (basınç, yarmada çekme ve eğilme dayanımı) ile elektriksel özdirencin belirlenmesi için numuneler üretilmiş ve toplam 90 gün boyunca 23±2 0C’de su içerisinde kür edilmiştir. Sonuçta çelik lif takviyesinin betonun elektriksel özdirencini düşürdüğü ve dolayısıyla iletkenliğini artırdığı tespit edilmiştir. Bunun yanında karma lifli KYB numunelerinin en düşük elektriksel özdirenç ve en yüksek iletkenlik ile sıcaklık artışına sahip olduğu görülürken, narinliği yüksek olan 13 mm boyunda mikro çelik lifin betonun elektriksel özellikleri üzerinde 6 mm boyunda mikro çelik life göre daha olumlu etkiye sahip olduğu bulunmuştur.

YNCRG is a combination of five traditional Chinese ingredients with medicinal properties. We studied its effects and mechanism of action on a rat model of non-alcoholic fatty liver with metabolic syndrome. Eight-week-old male SHRcp rat(s) and Wister Kyoto (WKY) rats were adaptively fed for one week, after which they were randomly divided into three groups, including the control group (n = 9), the YNCRG group (n = 8), and the WKY group (n = 8). The WKY group could freely consume water, the control group was provided water every day, and the YNCRG group was gavaged with an aqueous solution of YNCRG (3.6 g/kg body weight/day) for eight weeks. After eight weeks of intervention, YNCRG effectively reduced the weight of rats and significantly reduced the serum levels of AST, ALT, CHO, and TG compared to the weight of the rats in the control group. The RT-PCR results showed that mRNA levels of NF-κB, TLR4, TNF-α, and IL-1β increased, and the levels of MCP-1 and ICAM-1 also increased, but YNCRG effectively reduced the mRNA levels. The results of the Western blotting assay showed that YNCRG did not affect the AMPK/ACC signaling pathway, but it strongly promoted the phosphorylation of PKA, ERK, and C/EBPβ in rat livers. YNCRG also significantly promoted the phosphorylation of IRS-1 (Tyr465) but inhibited IRS-1 (Ser1101); both are upstream factors of ERK. We found that YNCRG can reduce the accumulation of lipids in the liver of rats with metabolic syndrome, probably by affecting lipid metabolism and the signaling pathway associated with inflammatory reactions.
Health Consumer Engagement, Enablement, and Empowerment in Smartphone-Enabled Home-Based Diagnostic Testing for Viral Infections: Mixed Methods Study
Authors: LeRouge Cynthia , Durneva Polina , Lyon Victoria , Thompson Matthew
Published: June 2022

Background

Health consumers are increasingly taking a more substantial role in decision-making and self-care regarding their health. A range of digital technologies is available for laypeople to find, share, and generate health-related information that supports their health care processes. There is also innovation and interest in home testing enabled by smartphone technology (smartphone-supported home testing [smart HT]). However, few studies have focused on the process from initial engagement to acting on the test results, which involves multiple decisions.

Objective

This study aimed to identify and model the key factors leading to health consumers’ engagement and enablement associated with smart HT. We also explored multiple levels of health care choices resulting from health consumer empowerment and activation from smart HT use. Understanding the factors and choices associated with engagement, enablement, empowerment, and activation helps both research and practice to support the intended and optimal use of smart HT.

Methods

This study reports the findings from 2 phases of a more extensive pilot study of smart HT for viral infection. In these 2 phases, we used mixed methods (semistructured interviews and surveys) to shed light on the situated complexities of health consumers making autonomous decisions to engage with, perform, and act on smart HT, supporting the diagnostic aspects of their health care. Interview (n=31) and survey (n=282) participants underwent smart HT testing for influenza in earlier pilot phases. The survey also extended the viral infection context to include questions related to potential smart HT use for SARS-CoV-2 diagnosis.

Results

Our resulting model revealed the smart HT engagement and enablement factors, as well as choices resulting from empowerment and activation. The model included factors leading to engagement, specifically various intrinsic and extrinsic influences. Moreover, the model included various enablement factors, including the quality of smart HT and the personal capacity to perform smart HT. The model also explores various choices resulting from empowerment and activation from the perspectives of various stakeholders (public vs private) and concerning different levels of impact (personal vs distant).

Conclusions

The findings provide insight into the nuanced and complex ways health consumers make decisions to engage with and perform smart HT and how they may react to positive results in terms of public-private and personal-distant dimensions. Moreover, the study illuminates the role that providers and smart HT sources can play to better support digitally engaged health consumers in the smart HT decision process.

BACKGROUND

Pregnancy serves as an important chapter in the life of women since more attention needs to be paid to both their physical and psychological health during this period. Adequate prenatal knowledge plays a key role in ensuring the health and safety of not only the pregnant women but also their fetuses and the entire family. With the development of information technology, web-based prenatal education has been brought into focus owing to its accessibility to comprehensive information, with high-quality information available to improve the quality of the overall gestation period, labor process, perinatal outcomes, and fetal outcomes.

OBJECTIVE

This study aims to investigate the present situation of web-based prenatal education and to predict the future research direction of web-based prenatal education in China, thereby providing insights into improving the quality of health care of pregnant women.

METHODS

A national cross-sectional study was conducted on 590,912 pregnant women in 31 provincial administrations of mainland China between August 2018 and August 2019. These pregnant women were initially recruited from local hospitals across the nation during antenatal and postnatal periods via a web-based education school. Demographic information and course completion status (including the categories and the number of courses they completed) of all the participants were collected.

RESULTS

A total of 590,912 pregnant women participated in the web-based prenatal education in 2018. Among them, 188,508 (31.90%) participants were excluded because they did not complete any course, while 17,807 (3.01%) actively participated in web-based prenatal education and completed more than 100 courses. There were 5 categories of web-based courses; almost half of the pregnant women attended the courses on first and second trimesters (293,262/590,912, 49.63% and 298,168/590,912, 50.46%, respectively). We found that pregnant women were more concerned about the gestational diet, fetal-related knowledge, and other precautions before the labor.

CONCLUSIONS

In the era of digitalization where information is rapidly disseminated, web-based prenatal education could become a more convenient, productive, and effective pathway for pregnant women since it could help them obtain adequate and optimal pregnancy-related information and gain more intellectual awareness about their pregnancy or preparation for pregnancy.
Automatic Assessment of Intelligibility in Noise in Parkinson’s Disease: A Validation Method (Preprint)
Authors: Moya-Galé Gemma , Walsh Stephen J , Goudarzi Alireza
Published: June 2022

BACKGROUND

Most individuals with Parkinson’s disease (PD) experience a degradation in their speech intelligibility. Research on the use of automatic speech recognition (ASR) to assess intelligibility is still sparse, especially when trying to replicate communication challenges in real-life conditions (i.e., noisy backgrounds). Developing technologies to automatically measure intelligibility in noise can ultimately assist patients in self-managing their voice changes due to the disease.

OBJECTIVE

The goal of this study was to pilot-test and validate the use of a customized web-based app to assess speech intelligibility in noise in individuals with dysarthria associated with PD.

METHODS

Twenty individuals with dysarthria associated with PD and 20 healthy controls (HC) recorded a set of sentences using their phones. Google Cloud ASR API was utilized to automatically transcribe the speakers’ sentences. An algorithm was created to embed speakers’ sentences in +6dB SNR multitalker babble. Results from ASR performance were compared to those from 30 listeners who orthographically transcribed the same set of sentences. Data were reduced into a response defined as a success event: whether the AI system transcribed a random speaker/sentence as well-or-better than the average of three randomly chosen human listeners. These data were further analyzed by logistic regression to assess whether AI success differed by speaker group (HC or speakers with dysarthria) or was affected by sentence length. A discriminant analysis was conducted on the human listener data and AI transcriber data independently to compare the ability of each data set to discriminate between HCs and speakers with dysarthria.

RESULTS

The data analysis indicated a 0.8 probability (0.65, 0.91)95%CI that AI performance would be as-good-or-better than the average human listener. AI transcriber success probability was not found to be dependent on speaker group. AI transcriber success was found to decrease with sentence length, losing an estimate 0.03 probability of transcribing as well as the average human listener for each word increase in sentence length. The AI transcriber data were found to offer the same discrimination of speakers into HC and speakers with dysarthria categories as the human listener data.

CONCLUSIONS

Automatic speech recognition has the potential to assess intelligibility in noise in speakers with dysarthria associated with PD. Results hold promise for the use of artificial intelligence with this clinical population, although a full range of speech severity needs to be evaluated in future work, as well as the effect of different speaking tasks on ASR.

Published: June 2022

This study was aimed to provide suggestions for improvement of the value stream, which was illustrated using Value Stream Mapping through the reduction of wastes. The measure of improvement was focused on the process cycle efficiency (PCE) of the Callaway Diablo golf glove production systems at Adi Satria Abadi limited company. At the initial condition of Value Stream Mapping, the identified wastes were inventories, delays, transports, and defects. Those four wastes were then mapped using Value Stream Analysis Tool (VALSAT). The process cycle efficiency (PCE) value of the initial condition was equal to 5.06 %. The improvement formulations for the proposed Value Stream Mapping were made by determining optimal crew size, work-cell design, Kanban design, and idea of autonomation. The improvement formulations of the proposed Value Stream Mapping could reduce work in process (inventories) of 57.81 %, delays amounting to 55.52 %, and transportations between work stations at 52.54 %. The company’s PCE increased by 12.06 %.

The method used is the native tapioca cross-linked with Sodium Tripolyphosphat 2 and 5 % and acylated with stearic acid 2 and 4 % under alkaline conditions. Cross-link tapioca then substituted with Nagara beans flour in the ratio 50:50. The highest degree of substitution found in tapioca starch modified with 5 % STPP and 2 % stearic acid, i.e 0.14. The only maximum viscosity of tapioca starch of cross-linked acylation STPP 5 % and stearic acid 2% higher than native tapioca (5220 cP). The breakdown viscosity lower than native tapioca (3651 cP), final and setback viscosity higher than native tapioca (3023 cP and 1454 cP), and pasting temperature higher than native tapioca starch (67.65 °C). When added with Nagara beans flour then the maximum, breakdown, final, and setback viscosity is descended and pasting temperature is 78.5 oC. It is concluded that the granule of tapioca crosslink STTP 5 % and acylation stearic acid 2 % and substituted with Nagara beans flour in the ratio 50:50 is not easily fragile and broken.

In recent years, South Kalimantan has experienced rice surplus and been appointed as one of the nation’s rice barns. However, the distribution pattern of rice produce in the province is not clearly described. The distribution pattern itself plays an important role in the context of rice availability and food security. The study is aimed at investigating the rice distribution pattern in South Kalimantan. The method used was supply-demand model with system dynamics approach. Price was the experimental variable. Initially, the stakeholder roles were investigated, followed by the development of causal loop diagram (CLD), stock and flow diagram (SFD), validation, verification, and finally simulations. South Kalimantan rice supply chain is generally operated by farmers, village middleman, larger collectors, rice millers, urban wholesalers (distributors), retail sellers, and consumers. The distribution pattern is influenced by the location of rice producing area, the location of large miller/collector/wholesaler area, rice variety, and consumer preferences.

This study examines the development of an approach for modeling the response of plant growth to nutrient solution temperature in hydroponic cultivation in a dynamic system. Nutrient solution temperature is one of the essential manipulating factors for plant growth in hydroponic cultivation. Determining the optimal control strategy of nutrient solution temperature during cultivation could lead to maximize the growth of the plant. By identifying the process using a dynamic system, the optimal control strategy can be determined. However, developing a dynamic model of plant growth to nutrient solution temperature is not easy due to physiological behavior between them are quite complex and uncertain. We propose the long short-term memory (LSTM) networks to identify and develop a model of dynamic characteristics of plant growth as affected by the nutrient solution temperature. Chili pepper plants were used to obtain time-series data of plant growth, with five different types of dynamic nutrient solution temperature patterns for system identification. The results showed that the proposed LSTM model provides promising performance in predicting the response of plant growth to nutrient solution temperature in hydroponic cultivation.

Published: June 2022

The natural ripening of ambon kuning, a typical banana widely consumed in Indonesia, tends to produce a non-uniform yellowish peel color of the fruits. Some degreening techniques using calcium carbide or ethepon, although improving the peel color appearance, may pose a safety risk compared to ethylene degreening, a technique using ethylene gas, a gas naturally produced by the fruit. This study aimed to determine the effect of ethylene degreening on changes in peel color, physical quality, and chemical content of ambon kuning and determine the combination of treatment that produces the best results. Taguchi design, with two levels for each of the three treatment factors (ethylene gas concentrations of 185.2 and 277.8 ppm, storage temperatures of 16±1 and 29±1 °C, and gas exposure time of 48 and 72 hours) was applied to banana samples stored in a hermetic bag in a temperature-controlled container. Grey Relational Analysis (GRA) was applied to get the best results considering multiple performance measures: peel color (measured as lightness L*-, green -a*-, and yellow b*-values), hardness of peel and pulp, total dissolved solids, total chlorophyll, and total carotenoids contents. The best results were obtained when degreening was carried out with a gas concentration of 185.2 ppm at a storage temperature of 16±1 °C for 48 hours.

S. litura was reared on artificial meals in a controlled laboratory setting at 26.1°C, 16:8 h L:D, and 65.5% RH at the National Agricultural Research Center (NARC) in Islamabad, Pakistan, to evaluate its premature, mature adult stage characteristics and predation by C. cornea. On the artificial diet, the results for various parameters, including total larval duration (19.1 days, 45 percent), pre-pupal period (3.4 days, 92 percent), pupal period (7.05 days, 83 percent), and total immature duration from eggs to adult stage (33.4 days, 33 percent), as well as percent survival rate, were recorded. On a corn-based artificial diet, data on the pre-oviposition period (2.4 days), oviposition period (5.4 days), post-oviposition period (1.63 days), female fecundity (1366 eggs), and adult longevity (8.66 days) of mature stages of S. litura were collected. When supplied as prey, the predator's biological parameters and predatory capacity, C. carnea, were tested on two stages of S. litura (eggs and 1st instar larvae). The studies indicated that the prey significantly affected the total larval duration, immature duration, and % survival rate. The entire larval period was greatly minimized when C. carnea was offered eggs of S. litura for feeding. Additionally, higher % survival and fecundity were observed feeding with S. litura eggs, followed by 1st instar larvae. C. carnea consumed 443 S. litura eggs and 395 S. litura larvae during its larval development. Daily consumption of C. carnea larvae reached a maximum of 73 eggs and 53 1st instar larvae of S. litura. Comparatively, C. carnea larvae recorded maximum egg predation compared to 1st instar larvae of S. litura and the shorter developmental period when eggs were offered as prey. Moreover, 3rd instar larvae of C. carnea were found more voracious than early instars.

Abstract: A crane is a machine that is primarily used to handle big weights in a variety of jobs. For instance, building work, shipbuilding, cargo transportation, and the cement industry may all benefit from this technology since it allows them to monitor and control their video processing systems using a PC. Cranes are frequently utilized in the industrial sector around the world to boost productivity and minimize personnel. Cranes are used to transport loads from one location to another. During this movement, there are typically unwanted vibrations and variations in the hoisted weight that must be managed. This paper gives a review of a new way for operating an overhead crane that uses a PC (Portable Computer), RF (Radio Frequency), and video processing approach to operate the crane from a certain distance. The crane movement is now controlled directly by the crane operator; nevertheless, due to the human inability to handle the crane efficiently, the crane speed is severely limited. This procedure allows a single employee to handle the crane from a greater distance by watching the location of each and every movement towards and away from the crane using a video processing technology and a radio frequency controlling system. The technology use computer vision to identify load location, which is then used to optimize crane operation. The intimation of the PC monitors reveals that the accident levels to become decline for handling the overhead crane even by operator, according to the technology for sustaining job.
Desulphurization of Jet Fuel using Merox Process: A Review
Authors: Kolhe Nitin S.
Published: June 2022

Abstract: The complexity of the petroleum industry is also reflected in the manner of its treatment units. The treatment of fuels such as jet fuels, petroleum derivatives, gasoline, etc. is imperative for the industry that needs efficient methods for processing them for further utilization. Earlier conventional methods in today’s times are somewhat looked at with the eyes of suspicion owing to the increased hazards and pollution resulting in increased environmental degradation and concerns. Hence, in order to decrease the environmental impact of conventional treating methods, new techniques and processes are being used. For this, the major milestone for decreasing environmental impact resultant of usage of fuel and petroleum derivatives is to decrease the sulphur quantities in the products. Therefore, the process of desulphurization has gained a major attraction in the petroleum industry. For the purpose of understanding the concept of desulphurization, especially in terms of desulphurization of jet fuels, the present study was conducted. This study is a review comprising of meta-analysis of existing literature on the topic. Moreover, apart from different forms of desulphurization, the present study focuses on two methods, i.e., hydrodesulphurization and Merox process, with more inclination to understand use of Merox process as a contemporary method for desulphurization of jet fuels.
