Authors: Abd Hadi Nurul Hidayah , Ooi Foong Kiew , Abdul Kadir Azidah , Ahmad Nur Syamsina
Published: June 2022

Channa striatus contains biochemical components and albumin, which elicit beneficial effects to the consumers. This review aimed to clarify the effects of Channa striatus consumption on humans and animals in in vivo studies. A systematic search in four electronic databases namely ProQuest, EBSCOhost, PubMed, and SpringerLink was performed to choose the studies on Channa striatus as the interventions, and its effects on animals and humans. The intervention involved: (i) Channa striatus with placebo-controlled, (ii) Channa striatus pre-treated and treated with drugs, (iii) Channa striatus with the combination of Chronic Unpredictable Mild Stress (CUMS), and (iv) Channa striatus pre-treated with amino acids and methylene blue. Thirteen animal studies and seven human studies were included in the final analysis. They investigated the effects of Channa striatus on wound healing, anti-depressant-like effects, anti-inflammatory effects, and effects on human diseases. Consumption of Channa striatus supplements was found in seven studies to benefit wound healing processes due to the contents of amino acids and fatty acids found in Channa striatus extract. Two studies were found regarding Channa striatus lipid decreased the corticosterone level and nuclear factor-kappa B, while two studies reported of DHA content in Channa striatus inhibited the production of inflammatory mediators. Channa striatus elicits a positive effect on the wound healing process and enhanced antidepressant-like and anti-inflammatory effects due to its high content of amino acids and fatty acids.

Published: June 2022

East African highland bananas (EAHBs) contain high amount of phenolics especially tannins, and are used to produce low-viscosity banana juice by a purely mechanical process. Occasional juice failure and cloudy appearance are the major problems facing juice production. The present work thus examined the variations in phenolic content of EAHB cultivars and their changes during ripening. The aim was to obtain a better knowledge of the various forms and amounts of phenolic compounds in different EAHBs, and how these properties may affect the ability of cultivars to produce low viscosity banana juice. Eleven banana cultivars including juice-producing and cooking bananas were harvested at the green maturity stage and analysed for total phenolic content (TPC), tannin content (TC), and tannin monomers at different ripening stages for five days. Analyses of TPC and TC were performed using the Folin-Ciocalteu method, whereas tannin monomers were identified by High-Performance Liquid Chromatography (HPLC) with UV detection. Multivariate analysis of variance was used to evaluate the relationship between cultivar, ripeness stage, and TPC/TC. A substantial difference in TPC was observed between juice-producing and cooking cultivars. The highest TPC was found in the juice-producing cultivar Kibungara (360.68 ± 17.12 mg GAE/100 g) at day 5 (the ripe stage), while the lowest TPC (8.67 ± 0.22 mg GAE/100 g) was observed in the cooking cultivar Malindi at ripening day 5. The results revealed that TPC and TC of banana pulp seemed to be more related to cultivar (p ≤ 0.05) than physiological changes during ripening (p ≥ 0.05). Further, HPLC analysis showed that among the individual catechins, gallocatechin was the predominant monomer in juice-producing cultivars, whereas in cooking cultivars, gallic acid was dominant. The present work indicated that high amount of total phenolic such as tannins especially gallocatechin in juice-producing banana cultivars favour the release of banana juice, and that analysis of phenolic compounds will provide a basis in the selection of banana cultivars with high potential for juice production.

Authors: Badrul Syafiqa , Jaafar Ahmad Haniff
Published: June 2022

A commercial rosemary extract was evaluated for antioxidant effectiveness in rendered chicken fat and antibacterial activity against selected foodborne pathogens. Four treatments were used in the experiment comprising of 25 and 50 ppm rosemary extract (RE), 200 ppm butylated hydroxyanisole (BHA; commercial antioxidant as positive control), and a negative control without antioxidant. All treatments were subjected to oxidative stability analysis tests including free fatty acid (FFA), peroxide value (PV), p-Anisidine value (AV), and total oxidation value (TOTOX), which were analysed weekly for a total period of seven weeks. In addition, RE was tested for antibacterial activity against Bacillus cereus, Escherichia coli, Klebsiella pneumoniae, Listeria monocytogenes, Salmonella enterica, and Staphylococcus aureus using disc diffusion assay (DDA). The results showed that the addition of 50 ppm of RE yielded the most potent antioxidant effect as evidenced by the lowest amounts for negative oxidation indicators (i.e., FFA, PV, AV, and TOTOX) as compared to the other treatments. BHA showed significant antioxidant effect between treatments for FFA and PV, and 25 ppm RE showed significant antioxidant effect between treatments for FFA only. DDA resulted in inhibition zones against all the tested bacteria ranging from 7.7 ± 0.6 mm (S. enterica; weakest inhibition) to 11.8 ± 0.4 mm (K. pneumonia; strongest inhibition). The findings showed that rosemary extract can be used as a natural antioxidant that effectively delays oxidation and exhibits antibacterial properties.

Published: June 2022

Vacuum packaging and modified atmosphere packaging (MAP) are important techniques used for the extension of fish and fish product shelf life. The present work evaluated the quality and shelf life of Rohu fish (Labeo rohita) by biochemical and microbiological analyses under different packaging types namely (1) unsealed pack (control), (2) vacuum pack, (3) MAP-1 (50% CO2 and 50% N2), and (4) MAP-2 (50% CO2 and 50% O2) at 3-day intervals during 18 days of refrigerated storage (4°C). Result showed that pH, total volatile base nitrogen (TVB-N), and thiobarbituric acid reactive substances (TBARS) values for all packaging conditions were within the acceptable limit during the storage period, except for TBARS value in MAP-2 sample. The total viable count (TVC) gradually increased with the progress of time in all packaging conditions. However, the TVC values were significantly (p < 0.05) lower on 9th and 12th day of storage in MAP samples as compared to that of the control sample. Considering the total bacterial counts, 7 log CFU/g, the shelf life was determined at approximately 8, 11, 13, and 16 days for control, vacuum pack, MAP-1, and MAP-2 sample, respectively. Therefore, MAP is recommended to be used to display and preserve fishes in the superstores.

Published: June 2022

The objective of the present work was to evaluate the effects of the administration of spearmint (Mentha spicata L.) infusion into drinking water (0, 5, and 10 g.L-1) in rabbits during 28 days of fattening on the microbiological and lipid stability of the end meat product, as well as the evaluation of meat and carcass quality. The rabbits were sacrificed, and the quality of the carcass and meat was evaluated. Once the meat was obtained, burger patties were made, which were then subjected to microbiological and physicochemical evaluation through the application of various treatments for 14 days. The results did not show an effect on the quality of the carcass; however, for the infusion treatment with 5 g of spearmint, the previous portion corresponding to the skeletal muscle, longissimus dorsi, was greater than the control treatment. Regarding the meat quality, the hardness parameter of the texture profile analysis was higher in the control and treatment with 5 g of spearmint. The microbiological analysis on day 0 showed that there was no growth of Staphylococcus in the treatments with spearmint infusion as compared to the control; the enterobacterial count at day 7 was higher in the control group than in the treatments with spearmint infusion; and on day 14, the total viable count was higher in control than in the treatments with spearmint infusion. In the physicochemical analysis, only the colour (L*, a*, and b*) showed significant differences in the parameters at 0 and 14 days for the control. In conclusion, the spearmint infusion in drinking water for fattening rabbits could influence the physicochemical and microbiological characteristics of the end meat product, and could be considered as an alternative for improving the lipid and microbiological stability of rabbit meat products.
A comparative study on the functional properties of mealworm (Tenebrio molitor) larvae and soybean protein isolates and hydrolysates
Authors: Yu Xiaotong , Oh Eunyoung , Kim Yookyung
Published: June 2022

The present work aimed to compare the functional and antioxidant properties of mealworm larvae and soybean proteins at different processing steps. The mealworm larvae protein isolate (MPI) was hydrolysed with 2% alcalase at pH 8 and 60°C for 3 h to produce mealworm protein hydrolysate (MPH). The content of amino acids were higher in MPI than in soybean protein isolates (SPI), except for those of threonine, arginine, glutamic acid, and serine. MPI contained a higher amount of hydrophobic amino acids (941.4 µmol/L) than hydrophilic amino acids (697.1 µmol/L). The emulsifying activity, stability, and fat absorption capacity of MPI were higher than those of SPI, whereas their water absorption and holding capacities were similar. Alcalase hydrolysis increased MPI solubility. MPI showed lower solubility at pH 3 - 9 than that of SPI, whereas MPH had higher solubility than that of soy protein hydrolysate (SPH). The foam expansion capacity and foam stability of MPI were lower than those of SPI, but hydrolysis improved those of MPI. MPI formed a gel at pH 5, 7, and 9 at 15% concentration or at pH 7 and 9 at 10% concentration. However, MPH showed no gel formation under any conditions. The total phenolic content and antioxidant capacity of MPI were higher than those of SPI. The DPPH activity of MPH (70%) was higher than that of MPI (18%), SPI (12%), or SPH (34%). MPI can be used as an alternative to SPI. Alcalase hydrolysis can increase the antioxidant effect, digestibility, and functionality of MPI as a sustainable ingredient in high value-added products.
Replacing animal fat with edible mushrooms: a strategy to produce high-quality and low-fat buffalo meatballs
Authors: Ramle Nurfatin Azma , Zulkurnain Musfirah , Ismail Fitry Mohammad Rashedi
Published: June 2022

The present work investigated the effects of replacing the fat in meatballs with enoki, brown beech, shiitake, white oyster, brown, or king oyster mushrooms on the physicochemical and sensorial characteristics of the reduced-fat meatballs. The water holding capacity of the reduced-fat meatballs increased significantly (14.4 - 36.5%) in parallel to a significant increase in the moisture (3.3 - 5.6%) and protein (4.1 - 7.5%) contents, with a decrease in fat (16.3 - 86.3%) content as compared to the control. No differences were found for the cooking yield and texture properties of the samples, except for the king oyster mushroom which reduced the hardness of the reduced-fat meatballs. The redness of the reduced-fat meatballs was comparable with the control, but reduced in yellowness and lightness. Most of the reduced-fat meatballs had better sensory characteristics as compared to the control, in particular, the meatballs with shiitake mushroom. In conclusion, all the mushrooms tested have the potential to be used as a full fat replacer in meatballs, except for king oyster mushroom which reduced the texture quality of the reduced-fat meatballs.
Effect of oxidation on the structural and functional properties of myofibrillar in Coregonus peled
Authors: Deng Xiaorong , Lei Yongdong , Liu Juan , Lu Shiling , Zhang Jian
Published: June 2022

The effects of the degree of oxidation (0.01 mmol/L FeCl3, 0.1 mmol/L ascorbic acid, 1 - 20 mmol/L H2O2) principally induced by Fenton systems on the structural and functional properties of Coregonus peled myofibrillar proteins (MP) was investigated. When the oxidation levels of MP increased, their carbonyl groups increased but sulfhydryl groups decreased (p < 0.05). SDS-PAGE analysis revealed more cross-linking and protein polymerisation in oxidised MP. FTIR properties suggested that oxidation increased conformational changes of MP. The functional results indicated that moderate oxidation (5 - 10 mmol/L H2O2) of MP improved their foaming capacity thus providing better functional properties; while excessive oxidation (≥ 15 mmol/L H2O2) led to the deterioration of their functional properties due to the formation of large aggregates, and therefore, should be avoided in their application in the food processing industry.
Effect of Dimocarpus longan var. obtusus seed aqueous extract on lipid oxidation and microbiological properties of cooked pork patties during refrigerated storage
Authors: Nitteranon Viriya , Sayompark Dhoungsiri
Published: June 2022

Meat spoilage is a predominant cause of rancidity, colour, texture, and flavour alterations in meat products. The use of natural compounds as antioxidants in food products has been of considerable interest for consumers in recent years. The purpose of the present work was therefore to determine the peroxide value, thiobarbituric acid reactive substances, physicochemical, and sensory characteristics of Lumyai Thao (LT) (Dimocarpus longan var. obtusus) seed aqueous extract incorporated in cooked pork patties during storage at 4°C for 21 days. Different concentrations of LT seed aqueous extract (0, 0.05, 0.10, and 0.20% (w/w)) and butylated hydroxyanisole (BHA) (0.01% (w/w)) were added to cooked pork patties. Results revealed that the addition of 0.20% LT seed aqueous extract was the most effective in inhibiting lipid oxidation in cooked pork patties, and the inhibition was observed to be stronger than that with BHA treatment (p < 0.05). LT seed aqueous extract at 0.20% could significantly preserve the colour of cooked pork patties (p < 0.05). The increasing concentration of LT seed aqueous extract decreased the moisture content, while the textural properties of cooked pork patties were enhanced. LT seed aqueous extract at 0.20% effectively inhibited the growth of microorganisms in cooked pork patties. A sensory analysis using a 9-point hedonic scale showed that the treatments of LT seed aqueous extract (0.05 - 0.20%) exhibited no significant difference in terms of appearance, taste, and overall acceptability of cooked pork patties in comparison to control (p > 0.05). The present work demonstrated the benefit of LT seed aqueous extract at 0.20% as a natural antioxidant, and that it may be used as a food preservative to extend the shelf life of cooked pork patties, and possibly other meat products.

Published: June 2022

Gynura procumbens (GP) grows abundantly in Southeast Asia. The present work was conducted to investigate the cardioprotective potential of ethanol extract of GP on cardiac markers, antioxidant levels, and histopathology of isoproterenol-induced myocardial infarction (MI). A total of 36 adult Sprague Dawley rats were randomly divided into six groups. Treatments were given via oral gavage for 28 days: two groups were given normal saline 0.9%; two groups were given GP250 mg/kg/day; and two groups were given GP500 mg/kg/day. On day 27 and 28, MI was induced with a subcutaneous injection of 85 mg/kg isoproterenol. The rats were sacrificed 48 h after the 1st injection. Cardiac markers, lipid peroxidation, oxidative status, and histopathological analyses were evaluated. Isoproterenol significantly increased the levels of troponin T, creatine kinase MB isoenzyme (CKMB), lactate dehydrogenase (LDH), and malondialdehyde (MDA), whereas the level of superoxide dismutase (SOD), catalase, and glutathione peroxidase were significantly decreased. In addition, the histopathological findings showed a necrosis of the myocardium as evidenced by neutrophil infiltration, and interstitial oedema with acceleration of apoptosis in MI. Interestingly, treatment with GP restored the levels of troponin T, LDH, MDA, SOD, and catalase significantly. Moreover, GP preserved the myocardial architecture while decreasing both necrosis and apoptosis. GP has the potential to limit myocardial injury after MI, and this is most likely achieved through its modulation of antioxidant enzyme activities.
Detection of spongy pulp in guava using light properties and near infrared spectroscopy
Authors: Noypitak Sirinad , Jaitrong Nuntinee , Terdwongworakul Anupun
Published: June 2022

Spongy pulp defect in guava is recognised by a dry-looking pulp with a brown colour, and not acceptable to consumers which causes substantial loss in value. Current detection of spongy pulp uses visual assessment of the flesh, which is half cut from the sample. The present work aimed to develop a classifying model based on non-destructive technique for the detection of spongy guava. Guava samples harvested at full maturity were determined for visible light properties, visible light reflectance, and near infrared reflectance. The light properties and light reflectance of guava peel were used to derive a classification model which was then compared with a near infrared reflectance model, which in turn provided absorbance of the flesh and peel using stepwise discriminant analysis. The models were used to classify the guavas into normal and spongy flesh groups, which were assigned with reference to the visual assessment on half cut samples. The classification accuracy for the model using gloss and light reflectance at 650 nm (chlorophyll b) was 90.4%. However, the model developed from the near infrared absorbance provided better accuracy (92.7%). It appeared that the largest wavenumber at 4,721 cm-1 contributed to the total sugar content, which implied that spongy and normal guavas had different total sugar contents in the flesh. The present work demonstrated the potential of near infrared spectroscopy to discriminate spongy from normal guavas. However, the accuracy of the classification could be further improved by analysing more samples from the next season.
Effects of freeze-dried Ecklonia cava hot water extract as a gel enhancer for fried fish cakes with threadfin bream (Nemipterus spp.) surimi
Authors: Shim Kilbo , Nam Kiho , Jeong Yeongyeom
Published: June 2022

In the present work, we used threadfin bream (Nemipterus spp.) surimi fish cakes to test the viability of freeze-dried Ecklonia cava hot water extract (ECWE) as a gel enhancer. The effects of freeze-dried ECWE on the gel strength and the colour of the fish cakes were investigated. The gel strength increased in fish cakes incorporated with 0.5% freeze-dried ECWE as compared to the control (no ECWE). The lightness and whiteness values of samples containing ECWE were lower than those of the control samples. Scanning electron microscopy (SEM) observations of fish cakes containing 0.5% freeze-dried ECWE exhibited a finer and more continuous matrix as compared to the control samples. Incorporating 0.5% ECWE improved the gel strength, and produced high-quality emulsions with a finely distributed gel network due to the presence of mannitol and some polyphenolic compounds in freeze-dried ECWE. The use of freeze-dried ECWE in the production of fish cakes is effective as a natural gel enhancer for surimi-based products.

Authors: Carrasco Cristina , González-Mateos Antonio , Gómez María de los Ángeles , Rodríguez Ana Beatriz
Published: June 2022

Nowadays, halal meat is attracting consumers as a healthier product. However, little is known about its nutritional content and possible health effects. A comparative analysis of the protein and amino acid contents between halal and non-halal meats (beef and lamb) was carried out in the present work. Additionally, a pilot study was also simultaneously performed to analyse the impact of their consumption on sleep/wake cycles and mood state profile in general population. Participants (n = 25) were asked to exclusively consume halal meats (1,000 g of gross weight/week) for 30 days. Objective and subjective sleep qualities, mood state profile, and levels of the urinary metabolites of serotonin and melatonin were assessed at baseline and post-intervention. Significantly higher contents of proteins and some amino acids were observed in halal-lamb and halal-beef, respectively. The consumption of halal meats for 30 days caused a slight improvement in men’s diurnal activity and mood state profile, as well as in women’s subjective sleep quality. Significantly higher urine levels of serotonin were also reported, particularly in men. Halal meat consumption seems to have a positive impact on sleep/wake cycles and mood state profile, likely due to the higher protein and amino acid contents. Additional scientific research is needed to support consumer trends in the coming years.

Published: June 2022

Zebrafish (Danio rerio), a freshwater fish, has become a favoured animal model to assess the teratogenicity effects of various compounds. Momordica charantia is a fruit traditionally used as a functional food to treat various ailments. In the present work, 80% ethanolic extract of M. charantia fruit was investigated for its teratogenicity effects on the zebrafish embryos. The embryos of 12 h post-fertilisation were immersed in the ethanolic extract at various concentrations of 250, 500, 750, 1,000, and 1,250 mg/L prepared in 2% DMSO. Microscopic observation was carried out every 24 h. Results showed an increased mortality rate, and a delayed hatching rate with increasing concentration. Some of the deformities observed included hyperactivity, crooked backbone, reduced pigmentation, awkward positioning, and coagulation at the highest concentration. Probit analysis resulted in 725.90 mg/L as the median lethal concentration (LC50). Chromatographic analysis revealed the presence of propanedioic acid, malic acid, contrunculin-A, glutamine, D-fructose, sorbopyranose, xylitol, galactonic acid, D-mannitol, and mannose. These compounds may contribute to the deformities observed in a concentration-dependent manner. Therefore, M. charantia fruit must be consumed with caution and within the recommended amount.

Published: June 2022

The present work aimed to produce edible oil that is low-cost and rich in ω-3 fatty acids (mainly α-linolenic acid; ALA). Silkworm pupae are industrial wastes which could be a good choice as the raw material for silkworm pupal oil (SPO) is. Solvent extraction (SE), supercritical fluid extraction (SFE), and aqueous enzymatic extraction (AE) were compared (oil yields of 28.34, 26.75, and 23.11%, respectively), and crude SPOs showed similar fatty acid compositions. Crude SPO extracted by SE contained a total tocopherol of 289.56 µg/g, which was higher than that of AE. SE was recommended due to its low cost, high oil yield, and high preservation of bioactive compounds, and a further refinement process was adopted only for crude SPO from SE. The fatty acid composition of the refined SPO was not different from that of the crude SPO, which contained 37.51% ω-3 fatty acids. A low acid value (AV, 0.65 mg KOH/g) and peroxide value (PV, 5.79 meq O2/kg), with almost no detectable toxicants indicated that SPO would be a high-quality edible oil for ω-3 fatty acid supplementation.

Published: June 2022

The present work demonstrated the application of a non-thermal technique to solidify nanometre-scaled atomised droplet using electrostatic atomiser or electrospray. The droplets were prepared in an aqueous solution, and consisted of bioactive compounds extracted from jasmine flower. The jasmine flower extracts were electrosprayed at various concentrations of 5, 15, and 25 wt%, with the working distances between the needle’s tip to an aluminium collector being 10, 20, and 30 cm. During the process, the water evaporation rate decreased from 2.02 to 1.02 nm3/s when the distance was increased from 10 to 30 cm at 5 wt% concentration. The same decreasing evaporation rate pattern was also observed when the concentration was increased from 5 to 25 wt%. On the contrary, increasing droplet fission numbers were observed as the distance was increased from 10 to 30 cm (i.e., from 7 to 406 at 25 wt% concentration) due to the electrostatic charge increment per unit area as the water left the droplet surface. Therefore, water evaporation and droplet fission number are important for solidifying the compounds when the droplets have exceeded their Rayleigh limit.

Published: June 2022

The article is devoted to the study of the perspectives of steganography to ensure integrity. The definition of information integrity is presented, which meets the new requirements and the definition of cybersecurity. Integrity is achieved through the control and recovery of information. The article provides a detailed analysis of existing approaches to the construction of modern steganometric systems. The greatest attention in the article was paid to the method of hiding information in graphic containers. The proposed method is a modification of the well-known method of replacing the least significant bits. The main difference from the known method is that not all least significant bits are changed. The selection of the bits to be changed is carried out using a pseudo-random sequence generator, while, thanks to the proposed algorithm, no more than 3.12 percent of the bits are changed, which is the limit of visibility for the steganalyst. There are 6.25 percent of information bits in such a message.

Published: June 2022

Recently, the diversity of data collected on both social networks and digital interfaces is extremely increased. This diversity of data raises the problem of heterogeneous variables that are not favourable to classification algorithms. Although machine learning and predictive analysis have significantly improved the efficiency of the classification in customer relationship management (CRM) systems, their performance remains very limited by heterogeneous data processing. In this paper, we propose a new predictive classification approach well adapted for targeting actual CRM systems. Our approach consists of preprocessing each type of feature and constructing a reduced array. From this reduced array, the class membership computations become very faster and perform the predictive targeting of a new instance great accurately. The results of the experiments carried out on four types of data from the CRMs showed that the proposed algorithm is a good tool for strengthening these systems not only to optimize their loyalty actions but also to efficiently acquire new customers.
Kurgudan Gerçeğe İslam Peygamberi Algısı: The Message (Çağrı)
Authors: ŞAHİN Ayşe
Published: June 2022

Oryantalizm, Doğu ve Batı arasındaki tarihsel kültürel ilişkiyi araştıran bilimsel disiplin olarak ortaya çıkmış zamanla bu iki kültür arası araştırmalar Doğu hakkında kurgusal bir tasvire dönüşmüştür. Bu hayali kurgunun kaynağı, Kuran’a ve Hz. Peygamber’e (s.) dayandırılmıştır. Bu bağlamda Batı’nın kimliğini Doğu üzerinden kurma teşebbüsü, Doğu’yu tanımadan tanımlama şeklinde yansımıştır. Batı, tanımladığı Doğu’yu televizyon ve sinema vasıtasıyla sunmaktadır. Oryantalist söylemde Hz. Muhammed’in (s.a.v) şehvet düşkünü, şiddet yanlısı, yaratıcı bir düşünür olduğu ifade edilmektedir. Bu durum sinemaya da konu edilmiştir. Hz. Muhammed’in (s.a.v) şahsında tüm Müslümanlar, çirkin davranış ve negatif bir kisve giydirilerek sinemada tasvir edilmektedir. Çalışmada bunun aksini gösteren nadir örneklerden birisi olan Mustafa Akkad'ın yönettiği, 1976 yapımı Çağrı filmi nitel doküman analiz yöntemi kullanılarak ele alınmıştır. Çağrı filminde, İslam’ın emir ve yasaklarının ne olduğu hakkında bilgi verilmiş Hz. Peygamber’in (s.) zevk düşkünü olmayan, adaletli, merhametli, yardımsever gibi özelliklerine vurgu yapılmıştır. Bu bağlamda oryantalist söylemdeki kurgu yerine gerçeğe daha yakın bir İslam ve İslam Peygamberi tasviri yapılmıştır.

To address the challenges of oil shale formation well wall instability,micro and nano pore blocking, long horizontal section well friction and borehole purification.We have analysed the nature of formation lithology,matrix pore size and specific surface by using linear expansion method,rolling recovery method and nuclear magnetic resonance method,and developed a white W/O drilling fluid system with an oil-to-water ratio of 70:30 by developing emulsifiers,tackifying and shear strength-improving agents,plugging agents and preferably filter loss agents,and wetting agents.The system was evaluated by using the breakthrough pressure test triaxial compression test and relaxation measurement method in the laboratory. The evaluation results showed that the system could not only maintain the strength of the rock sample but also improve the plasticity of the rock sample after the drilling fluid soaked with the breakthrough pressure of 6.5MPa,and it had good suspension capacity after the relaxation value reached 60s.The field test results show that the system has stable rheological properties and solves the problems of well wall instability and borehole purification,with the well diameter expansion rate of only 3.8% and the mechanical drilling speed of up to 10.85m/h.The SY-1 well has set a record for the longest horizontal section of 1800m in the Liaohe River oil area.

Authors: Qian Zhiwei
Published: June 2022

In response to the difficult problem that the lithology of the target formation of Well RT1 is prone to hydrate and expand,the bottom hole temperature is high,and bicarbonate pollution is prone to occur, by analyzing the formation characteristics and technical difficulties of drilling fluids,and preferentially selecting key treatment agents such as organic salts,filtrate reducers and blocking agents,the formulation of high temperature resistant organic salt drilling fluid is developed.The results of laboratory experiments show that the drilling fluid system is resistant to temperatures up to 180℃,the difference in density between the upper and lower parts is only 0.06g/cm3 after hot rolling for 8 days,the HTHP filtration loss is less than 4 ml,the 16-hour expansion rate is only 0.88%,the secondary rolling recovery rate reaches 92%, the core blocking rate is more than 75%,and the resistance to bicarbonate contamination is more than 22000mg/L.It has good rheological properties,filtration properties,inhibition performance,plugging performance, anti-bicarbonate pollution performance and sedimentation stability performance.The results of the field experiment show that the good diameter expansion rate of the lower part of the two-open lower and the three-open lower is only 3.8%,the drilling fluid still has good rheological properties at 170℃,and the performance varies slightly when the bicarbonate ion concentration in the drilling fluid is 30230mg/L. It indicates that the developed high temperature resistant organic salt drilling fluid has effectively solved the difficult problems of easy hydration,expansion and dispersion of the mudstone in the target layer of well RT1,high temperature at the bottom of the well and bicarbonate contamination,and has broad application prospects in high-temperature deep wells.

THE BROADENING OF CREATIVE WRITING STUDENTS’ CONCEPTS ABOUT FANFICTIONS
Authors: Placido Carlos Eduardo de Araujo
Published: June 2022

The multimodal gerne fanfictions have been one of the commonest cyberliterary texts produced on the internet. However, the various definitions of fanfictions seem not to be related to the cyberspace (JENKINS, 1992; TUSHNET, 1997; PUGH, 2005; THOMAS, 2006; HELLEKSON, 2014; COPPA, 2017). Therefore, the first objective of this article was to identify the students’ actual concepts about fanfictions (VYGOTSKY, 2004, 2007). The qualitative data was collected in a fanfictional creative writing (FCW) course. This course was organized and taught based on the Vygotskian sociocultural theory. The second objective was then to analyze if the FCW course did help its students broaden their concepts about fanwriting. As a result, the FCW students displayed signs of syncretizing, complexifying and conceptualizing about the fanwriting process.

Escherichia coli O157: H7 strain was used as the standard strain for bacteriophages isolated from polluted environmental foci and animal waste-contaminated waters, and some of the enteroinvasive Escherichia coli strains previously isolated from sporadic cases were used to determine the host diversity of phages. The physiological properties of bacteriophages specific to Escherichia coli O157:H7, designated Escherichiaphage NL1, were studied. After the isolation step, bacteriophages were purified and their titer was increased. Cross-antigenic properties of the hosts were investigated with Escherichia phage NL1 phage. One-step growth curve parameters such as adsorption time of phages, latent period, burst size, multiplicity of infection value (MOI) were determined. Results showed that bacteriophage NL1 completely lysed the E.coli O157:H7 (RSKK 09007) and E.coli O:164 RSKK 324. In the study, the effects of phage NL1 only on E.coli O157:H7 were investigated. The calculated highest titer was determined as Optimal multiplycity of infection (2.16x108). It was determined that the latent period lasted for 20 minutes and the phage was reached the burst size at approximately 90 minutes.

Man has needed and used energy at an increasing rate for the substance and well - being since time immemorial. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway stations, temples, etc., are overcrowded all round the clock. Now days energy and power are the one of the basic needs in this modern world. Energy demand is increasing day by day. On the other hand, the many energy resources are getting exhausted and wasted. Millions of people move around. This whole energy is wasted. If this energy made possible for utilization, then it will be a great invention. In this project we are converting non-conventional from just walking foot step into electrical energy. This project uses simple drive mechanism such as rack and pinion assembly. The control mechanism carries the rack pinion; D.C generator, gears, shafts, plates and multi-meter to show output. We have discussed the various applications and further extension. Non-conventional energy system is very essential at this time to our nation. Non- conventional energy using foot step needs no fuel input power to generate the electrical power. In this project the simple drive mechanism such as rack and pinion assembly mechanism is used for generating power by utilization of force which is obtained during the walking on steps is converted in to electrical energy with the help of mechanical systems. We have discussed its various alternate applications with extension also. The power generation is much worthy but it has little initial cost-effective factors.

Filters are devices that remove undesirable or polluting particles from a required environment. Filters are used to ensure the purity of electrical power in electrical systems. Power filters are used to handle power quality concerns such as power factor, voltage stability, and harmonics. There are two types of filters: passive filters and active filters. The current waveform is injected by the active filter in response to the recognized harmonic in the unit. The active filter is made up of electronic semiconductor switching devices. It takes current from an external source (typically DC) and injects it into the system as a specified current waveform to eliminate harmonics. The ability to give signal gain through amplification and lower output impedance are two major advantages of active filters. Active harmonic filters have seen numerous adjustments and upgrades in their implementation to suit specific applications since its introduction. As a result, series and shunt active filters have been implemented to meet the application's needs. Shunt Active Power Filter as a Smart Impedance with proportional resonant (P + R) controller is presented in this work to reduce current harmonics. The results of a MATLAB simulation model are presented in this paper.
An RCG-based analysis of the Translation of Polysemous Verb ‘Yao’ in A Dream of Red Mansions
Authors: Humblé Philippe , Zhang Tao , Xu Wen
Published: June 2022

This research investigates the applicability of a relatively new concept from cognitive linguistics, Radical Construction Grammar (RCG) (Croft：2001), as an analytical model in the study of the translation process. Based on the fundamental concepts of RCG, this article puts forward a construction-oriented view of translation and the following six construction-based translation principles: the semantic function priority principle, the conceptual space-based principle, the gestalt principle, the interactivity principle, the taxonomic principle, and the prototype priority principle. These RCG-based translation conceptions and principles will be detailed and verified in translation examples with the Chinese polysemic word 'yao' in different constructions, selected from the translation of the Chinese classic A Dream of Red Mansions (Cao & Gao:1994). The results of this study show that RCG can provide an innovative linguistic model for translation studies, particularly for the issue of polysemy.
