In Africa, Prostephanus truncatus is a destructive pest of economic importance which has assumed a serious pest status on stored maize and dry cassava chips. This study investigates the effect of processing methods of cassava varieties Manihot esculenta on the proximate composition before and after exposure to P. truncatus. The four cassava varieties used for this study were; TMS 0505, TME 419, NR 8082 and TMS 0581 subjected to two processing method parboiling and plain sun-drying at temperature 28-34oC and relative humidity of 65-75%. The experiment was carried out in a Complete Randomized Design. Proximate composition was carried out to determine the Moisture, Ash, Crude fibre, Fat, Crude Protein and Carbohydrate of the different samples. Analysis of Variance was used for the statistical analysis of the data obtained. The result reveals that the proximate composition of the sundried chips are significant at P<0.05%. All the proximate contents of the sample were significant at P<0.05% before the introduction of P. trucatus. After the introduction of P. truncatus and the storage period of 30days, the sundried sample had a higher reduction in the moisture contents of TMS 0505 with 13.05±0.00a and carbohydrate contents of NR 8082 with 50.0±0.00a. The activity of P. truncatus also has a negative impact on some of the nutritional components of cassava chips.
在非洲,圆茎蚜是一种具有重要经济意义的破坏性害虫,对储存的玉米和干木薯片造成严重危害。研究了木薯品种马尼奥特(Manihot esculenta)不同加工方法对其暴露前后近似成分的影响。本研究使用的四个木薯品种是;TMS 0505, TME 419, NR 8082和TMS 0581在温度28-34℃,相对湿度65-75%的条件下,进行过沸煮和普通晒干两种处理方法。试验采用完全随机设计。采用近似组成法测定了不同样品的水分、灰分、粗纤维、脂肪、粗蛋白质和碳水化合物。采用方差分析对所得数据进行统计分析。结果表明,在P<0.05%的情况下,干屑的近似组成显著。所有样品的近似值含量均显著在P<0.05%。经干枯处理后的干枯样品中,TMS 0505的含水率降低了13.05±0.00a, NR 8082的碳水化合物含量降低了50.0±0.00a。该菌的活性对木薯片的某些营养成分也有负面影响。

Edible vegetable oils are very important resource that are in high demand globally, and used in a variety of ways as they are considered a concentrated source of energy for human beings and carriers of oil-soluble vitamins which supply the essential fatty acids that are required for a wide range of biological and physiological functions. This work was aimed at evaluating the physicochemical properties, cholesterol content and analyzes the vitamin A contents of commonly sold vegetable oils in Ado Ekiti metropolis. The physicochemical parameters such as density, acid value, iodine value, peroxide value and saponin value, cholesterol content as well as Vitamin A content were all analyzed using standard analytical methods. Results of the physicochemical analysis showed that there was no significant difference (p>0.05) in the densities of the oil samples, It was observed that sample 4 oil showed maximum (1.58 mgKOH/g) and sample 6 showed minimum (1.38 mg KOH/g) acid values. Highest iodine values were observed in sample 8 (68.13 g/I2/100g) and lowest in sample 4 (56.38 g/I2/100g). Peroxide value was found to range from 2.18 meq O2/kg to 2.67 meq O2/kg, while saponin value was highest in sample 6 (130.3 mg KOH/g) and lowest in sample 8 (122.4 mg KOH/g). All the oil samples were found to contain cholesterol which ranged from 1.21±0.04 mg/dl (sample 1) to 4.58±0.01 mg/dl (sample 4), while the vitamin A content ranged from 674.80±10.26 IU/g (sample 2) to 877.97±20.52 IU/g (sample 8). Findings from this research showed that the researched oils meet the acceptable physicochemical standard. However, the cholesterol levels were against the inscriptions of cholesterol free on the labels.

Background: Diabetes is a health problem worldwide. The prevalence of diabetes has been steadily increasing for the past three decades. Diabetes prevalence is growing most rapidly particularly in low- and middle-income countries. Areas undergoing rapid westernization and rapid nutrition transition are seeing the greatest increase in prevalence suggesting that environmental factors are important. Diabetes is known to have no cure but can be managed through diet and modification of lifestyles. The aim of this study was to evaluate the prevalence and the predictors of diabetes and its management in Kumba District Hospital (KDH). Study Design: A retrospective, and a cross sectional survey was done where semi structured questionnaires were administered to subjects. Methodology: Information from the hospital record for the past four years was used to evaluate the trend in the prevalence of diabetes. Information from questionnaires was used to assess the prevalence and management of the disease. Fasting plasma glucose was measured to know their diabetic status. Results: The results revealed an increasing trend in the prevalence but the increase was not statistically significant. The results showed that, there was an association between diabetes prevalence and management. The overall prevalence of diabetes from the study was evaluated at 43.98%. Age, level of education, dietary habit and alcohol were found to influence the prevalence of diabetes significantly. Management with respect to therapeutic education, and monitoring of blood sugar were statistically significant. The significant predictive variables of the occurrence of diabetes base on Ordinary least squares were found to be age, level of education, therapeutic education, alcohol consumption, sex, and frequency of eating white rice. Conclusion: The study revealed that, diabetes is highly prevalent among older persons and the less educated in KDH. Public health officials should educate the public on the risk factors of diabetes, and implement guidelines for adequate control and management.

This preliminary risk assessment is a result of self-tasking by the Panel on Biological Hazards, Norwegian Scientific Committee for Food Safety. The suggestion was offered to the Norwegian Food Safety Authority (Mattilsynet), which responded and requested a risk profile, or a preliminary risk assessment, to evaluate whether a full risk assessment would be needed at a later date. Yersinia enterocolitica is one of a few zoonotic bacteria that have a stable reservoir within the domestic animal population in Norway. This bacterial species has been isolated from human patients with acute enteritis, who sometimes exhibit symptoms resembling appendicitis. Y. enterocolitica has attracted considerable attention due to its ability to cause serious post-infectious complications. Serious clinical consequences occur relatively often with Y. enterocolitica as a relatively high frequency of people in Norway possess the tissue type HLA-B27. A severe sequela linked to this tissue type is reactive arthritis. The cold climate in Norway may enhance growth of Y. enterocolitica. Although the predominant cause of yersiniosis in Norway is Y. enterocolitica O:3, and the pig is considered the main source of infection, the relative contribution of pork consumption compared with other risk factors, for example drinking untreated water, is unknown. In Norway, a decline in human cases of yersiniosis has been recorded since the beginning of the 1990s. This decline has been attributed to implementation of improved slaughtering methods, including enclosure of the anus into a plastic bag after rectum-loosening. In Norway, most fattening pigs are slaughtered at the age of 150 to 180 days. By this age the tonsils may be an even more significant source of human pathogenic Y. enterocolitica than intestinal contents, since the occurrence in the intestinal tract and faeces is reduced at the time of slaughter. Accordingly, hygienic handling of the head and the plucks during slaughter and dressing is very important to avoid contamination of the carcass. The most efficient way to limit the spread from tongue and tonsils is probably decapitation early on in the carcass dressing procedure. In such a procedure, the head, including tongue and tonsils, should be removed on a separate line. Also, avoidance of incision of the sub-maxillary lymph nodes might reduce the spread, Epidemiological data suggest that it is possible to reduce the herd prevalence of Y. enterocolitica O:3 by minimising contact between infected and noninfected herds. Further, attempts to reduce the prevalence at the top levels of the breeding pyramids may be beneficial for the industry as a whole. The meat industry might be able to categorise herds using serological methods, and use these results in its strategy to reduce the risks for consumers. However, such a strategy has to be evaluated in a cost benefit context. The apparently low prevalence of pathogenic Y. enterocolitica in food may be due to lack of suitable select

In 2006 the, the Panel on Nutrition, Dietetic Products, Novel Food and Allergy in the Norwegian Scientific Committee for Food Safety (VKM) adapted a Danish model for assessing applications concerning food fortification into Norwegian conditions. The fortification model is presently used by the Norwegian Food Safety Authorities as a tool in the management of applications on food fortification. The model from 2006 was based on intake calculations from dietary surveys from 1997-2000. Since then, new national dietary surveys have been published. These are the comprehensive nationwide Norwegian dietary surveys among adults (Norkost 3, 2010-2011), among young children (Småbarnskost, 2007) and infants (Spedkost, 2006-2007). The Norwegian Food Safety Authority has requested VKM to implement the new data into the fortification model from 2006. In the model from 2006 it is assumed that 25% of the energy in the diet can be derived from fortified foods and drinks. Information from the Norwegian Food Safety Authority, including about a pilot study for Norkost 3 suggested that the overall intake of fortified foods and drinks was marginal. From management of applications for fortified foods, the Norwegian Food Safety Authority also experienced that there are few fortified foods on the market in Norway. The Norwegian Food Safety Authority has therefore requested VKM to evaluate whether the assumption that 25 energy percent (E%) deriving from fortified foods can be reduced to 15 E%, and if such a reduction will have health implications. In addition, the Norwegian Food Safety Authority has asked VKM to perform an evaluation of the safety factors in the model. VKM argues that the model for fortification should be based on the dietary intake of vitamins and minerals at the 95th percentile level in various age groups. This is in accordance with risk assessments performed in European Food Safety Authority (EFSA), and will assure that the dietary intake in a majority of the population will be covered, still within a reasonable secure use of dietary exposure calculations. Mean intake of vitamins and minerals from food supplements (among users only) was chosen, in an attempt to reduce the impact of those with a high intake of supplements. The intake at 95th percentile from the diet plus the mean nutrient intake from supplements is deducted from the tolerable upper intake level (UL) for each nutrient in each age group, giving the maximum amount of nutrients that can be “allocated” for food fortification. The maximum amount of a nutrient that can be “allocated” is then distributed over the energy intake at the 95th percentile level. In this manner an estimate is made showing which age group is most likely to have an excessive intake of a certain nutrient. VKM does not have access to any other information about available fortified foods on the Norwegian market than the information given by the Norwegian Food Safety Authority.

coli is part of the normal gastrointestinal microbial flora of humans and animals. E. coli bacteria causing enteric/diarrhoeal disease are categorized into different groups based on their virulence properties and pathogenic features in humans. Enterohaemorrhagic E. coli (EHEC) are E. coli strains that cause bloody diarrhoea and haemolytic uraemic syndrome (HUS) in humans, and have a defined zoonotic association. The major virulence factor of EHEC (and the actual cause of HUS) is the ability to produce Shiga toxins (Stx), thus the name Shiga Toxin Producing E. coli (STEC). With enteropathogenic Escherichia coli (EPEC), the diarrhoea in these patients is due to attaching and effacing (A/E) lesions in the enteric epithelium. This risk assessment was conducted after a human outbreak of STEC O103 in 2006, associated with contaminated dry-fermented sausages. The Norwegian Scientific Committee for Food Safety (Vitenskapskomitéen for mattrygghet), Panel on Biological Hazards, was asked by the Norwegian Food Safety Authority (Mattilsynet) for a risk assessment regarding shiga toxin-producing E. coli (STEC) in the Norwegian meat chain, with emphasis on dry-cured sausages. In response, an ad hoc Working Group of experts was appointed with the mandate to draft a risk assessment regarding this issue. The current report approaches the task by following and analysing the entire process, from the origin of the meats at farm level, to the final production and storage of dry-cured sausages. An overall aim of the report has been to identify and describe potential intervention options in various parts of this chain. The main conclusions from the risk assessment are as follows: It is not possible to give any reliable quantitative estimates of the current risk associated with consumption of dry-cured sausages. There are no clear indications of any general change in the epidemiology of STEC infections in humans in Norway over the last decade. There is no documentation that there has been any change in the occurrence of various STEC in the domestic animal reservoir during the last decade. The combination of proper slaughter hygiene and use of thermal decontamination of sheep, cattle and pig carcasses represents an efficient way to reduce STEC contamination. This approach would not only cause a reduction in the contamination level of STEC, but also provide a general beneficial effect on the level of other enteric pathogens, such as Salmonella and Yersinia enterocolitica.

大肠杆菌是人类和动物正常胃肠道微生物菌群的一部分。引起肠道/腹泻疾病的大肠杆菌根据其对人类的毒力特性和致病性特征被分为不同的组。肠出血性大肠杆菌(EHEC)是引起人类出血性腹泻和溶血性尿毒综合征(HUS)的大肠杆菌菌株,并具有明确的人畜共患关系。肠出血性大肠杆菌(也是溶血性尿毒综合征的实际原因)的主要毒力因子是产生志贺毒素(Stx)的能力,因此被称为产志贺毒素大肠杆菌(STEC)。患有肠致病性大肠杆菌(EPEC),这些患者的腹泻是由于肠上皮的附着和消退(A/E)病变。这一风险评估是在2006年与受污染的干发酵香肠有关的产肠毒素大肠杆菌O103人间暴发之后进行的。挪威食品安全局(Mattilsynet)要求挪威食品安全科学委员会(vitenskapskomitsamen for mattrygghet)生物危害小组对挪威肉类链中产生志贺毒素的大肠杆菌(STEC)进行风险评估,重点是干腌香肠。为此,任命了一个特设专家工作组,其任务是起草关于这一问题的风险评估报告。目前的报告通过跟踪和分析整个过程来完成这项任务,从肉类在农场一级的起源,到干腌香肠的最终生产和储存。该报告的总体目标是确定和描述在这一链的各个部分的潜在干预方案。风险评估的主要结论如下:不可能对目前与食用干腌香肠有关的风险给出任何可靠的定量估计。在过去十年中,没有明确的迹象表明挪威人类产志贺毒素大肠杆菌感染的流行病学有任何普遍变化。没有文献表明,在过去十年中,家畜储存库中各种产志贺毒素大肠杆菌的发生率有任何变化。适当的屠宰卫生和对羊、牛和猪尸体进行热消毒相结合是减少产肠毒素感染的有效方法。这种方法不仅会降低产肠毒素大肠杆菌的污染水平,而且还会对其他肠道病原体(如沙门氏菌和小肠结肠炎耶尔森菌)的水平产生普遍有益的影响。在发酵过程中适当使用发酵剂,再加上较高的发酵温度,将降低受污染的干腌香肠中产大肠杆菌生长的可能性。较高的发酵温度、过程中较低的pH值和最终产品的热处理相结合,应有效消除因食用干腌香肠而传播产大肠杆菌感染的潜在风险。减少5个对数是可能的。现有的技术选择可以显著减少潜在病原体通过肉类,特别是通过干腌香肠的传播。最重要的数据缺口是缺乏关于挪威人类产肠毒素大肠杆菌感染实际发生情况的信息。有必要改进实验室诊断程序和流行病学监测,同时在卫生保健系统中改进报告和追踪。建议对各种家畜进行适当设计的基线研究,以提供关于各种血清型的发生及其存在的毒力因子的数据。此外,这将为与人类分离株进行比较提供更好的基础。

E. coli bacteria causing enteric/diarrhoeal disease are categorized into different groups based on their virulence properties and pathogenic features in humans. Enterohaemorrhagic E. coli (EHEC) are E. coli strains that cause bloody diarrhoea and haemolytic uraemic syndrome (HUS) in humans, and have a defined zoonotic association. The major virulence factor of EHEC (and the actual cause of HUS) is the ability to produce Shiga toxins (Stx), thus the name Shiga Toxin Producing E. coli (STEC). With enteropathogenic Escherichia coli (EPEC), the diarrhoea in these patients is due to attaching and effacing (A/E) lesions in the enteric epithelium. \u0000 \u0000 \u0000This risk assessment was conducted after a human outbreak of STEC O103 in 2006, associated with contaminated dry-fermented sausages. \u0000 \u0000The Norwegian Scientific Committee for Food Safety (Vitenskapskomitéen for mattrygghet), Panel on Biological Hazards, was asked by the Norwegian Food Safety Authority (Mattilsynet) for a risk assessment regarding shiga toxin-producing E. coli (STEC) in the Norwegian meat chain, with emphasis on dry-cured sausages. In response, an ad hoc Working Group of experts was appointed with the mandate to draft a risk assessment regarding this issue. \u0000 \u0000The current report approaches the task by following and analysing the entire process, from the origin of the meats at farm level, to the final production and storage of dry-cured sausages.

Pasteurisation of all consumer milk became mandatory in Norway in 1953, and this has been an important component of the protective measures that have reduced the incidence of milk and food borne diseases. In 2004, a complete recast of the hygiene legislation addressing both food hygiene and veterinary aspects was adopted by the European Union, the so-called “Hygiene package”. According to this legislation, each member state may, on its own initiative, prohibit or restrict the marketing of some foods like raw milk or raw cream, intended for direct human consumption within its territory. In response to this, the Norwegian Food Safety Authority (Mattilsynet) commissioned the Panel on Biological Hazards of the Norwegian Scientific Committee for Food Safety (Vitenskapskomitéen for mattrygghet), to prepare a risk assessment regarding the consumption of raw milk and raw cream. In response, an ad hoc Working Group of experts was appointed with the mandate to draft a risk assessment which should include the following components: identification and characterization of microbiological hazardous agents present in Norwegian raw milk; characterization of the public health consequences of these agents; assessment of the probability of transmission of these agents to humans by distribution of raw milk and cream. Additionally, the risk assessment should identify potential hazards to human health from the importation of raw milk, identify hazards associated with equipment used for production and storage of raw milk, and assess the risks associated with the potential transfer of antimicrobial resistance genes. Observations concerning infections related to consumption of raw milk and raw cream in Norway, other European countries and North America, show that a number of pathogenic microorganisms, including emerging pathogens, can occur in raw milk and raw cream. These pathogenic microorganisms and their toxins may represent a real threat to human health. The panel concluded that the risks associated with E. coli O157:H7 and other EHEC, C. jejuni and L. monocytogenes in raw milk and cream are high. Furthermore the importation of raw milk to Norway may result in the (re)introduction of microorganisms, which have been eradicated, or never previously have been present, in Norway. This can have serious consequences for both human and animal health.
1953年,挪威对所有消费者的牛奶强制进行巴氏消毒,这是减少牛奶和食源性疾病发病率的保护措施的重要组成部分。2004年,欧盟对食品卫生和兽医方面的卫生立法进行了全面修订,即所谓的“卫生一揽子计划”。根据该立法,每个成员国可以主动禁止或限制在其领土内直接供人类食用的某些食品,如生牛奶或生奶油的销售。为此,挪威食品安全局(Mattilsynet)委托挪威食品安全科学委员会生物危害问题小组(vitenskapskomitsamen for mattryghet)编写一份关于食用生牛奶和生奶油的风险评估。为此,任命了一个特设专家工作组,其任务是起草一份风险评估报告,其中应包括以下内容:鉴定和描述挪威原料奶中存在的微生物危险剂;描述这些物质对公共卫生的影响;通过分发生牛奶和奶油评估这些病原体传染给人类的可能性。此外,风险评估应确定原料奶进口对人类健康的潜在危害,确定与生产和储存原料奶所用设备有关的危害,并评估与抗菌素耐药性基因潜在转移有关的风险。在挪威、其他欧洲国家和北美,对与食用生奶和生奶油有关的感染的观察表明,许多致病微生物,包括新出现的病原体,可能发生在生奶和生奶油中。这些致病微生物及其毒素可能对人类健康构成真正的威胁。该小组得出结论,生牛奶和奶油中的大肠杆菌O157:H7和其他肠出血性大肠杆菌、空肠梭菌和单核增生乳杆菌的风险很高。此外,向挪威进口原料奶可能导致(重新)引入微生物,这些微生物在挪威已经被根除,或者以前从未存在过。这可能对人类和动物健康造成严重后果。

The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of Lactobacillus paracasei ssp. paracasei F19 (F19) in processed cerealbased baby foods intended for small children 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search. A notification regarding two products of processed cereal-based baby foods (hereafter called cereals), intended for small children and supplemented with the bacterium F19 initiated this work. A daily supply of a monoculture of a particular bacterial strain in large quantities to an age group without a fully established intestinal flora, may have unknown adverse effects. There are however, to our knowledge, no studies investigating possible short or long term adverse health effects of F19 in processed cereal-based baby food given to children 13 months onwards. The documentation and information provided by the notifier regarding the genetic stability of F19 in the two products during processing and storage, is considered insufficient and does not allow any conclusions to be drawn. Moreover, the documentation obtained is not conclusive regarding the antibiotic resistance pattern of the bacterial strain used in the products in question, as the information on different antibiotics is partly inconsistent. The information about specific localization (chromosomal, plasmid) of the resistance genes is not sufficient. Studies demonstrate that F19, as well as other bacterial strains considered probiotic, is able to “crosstalk” with enterocytes in mice and that the result of the “crosstalk” depends upon the microbiota present. Whether F19 has a similar “crosstalk-profile” in humans is unknown. However, as the strain is originally of human origin, it seems reasonable to assume that such “crosstalk” may occur. Thus, before giving F19 daily for months and years, it seems reasonable to ask for additional molecular and physiological studies to unravel the functional impact of possible changes in genetic expression in children. Lactobacillus infections do occasionally occur, mainly as bacteremia, endocarditis and localized infections (e.g. abscesses, peritonitis, and meningitis) in patients with severe underlying diseases. Most of them are elderly, but children are not excluded. The species most often isolated are L. casei and L. rhamnosus, followed by L. paracasei. The increasing use of immunosuppressive therapy and broad spectrum antibiotics which are ineffective against Lactobacillus, might increase the importance of these bacteria as possible pathogens. In order to be able to draw any conclusions regarding beneficial effects of F19, there is a need for randomized placebo-controlled studies in larger populations and in the relevant age group.

The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of B. lactis Bb12 in baby foods focusing on the age groups 4-6 months, 612 months and 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search. An notification for use of processed cereal-based baby foods (from now on called cereals) intended for infants and small children supplemented with the microorganism Bifidobacterium lactis (B. lactis) Bb12 in Norway initiated this work. Studies of potential hazards and positive health effects from cereals containing B. lactis Bb12 intended for infants and young children have not been reported in the available literature. However, reports on safety of and positive health effects from infant and follow on formula supplemented with B. lactis Bb12 are available and have been assessed by VKM. In most of these clinical studies B. lactis Bb12 was administered in combination with other probiotic strains. Clinical studies report no serious adverse events of infant formula supplemented with B. lactis Bb12. The effect of long term daily consumption of such supplemented formula by the actual age groups is not known. A few studies have demonstrated some effect of supplementing baby food with probiotics, including B. lactis Bb12, on diarrhoea and atopic eczema while other studies do not show such effects. Thus, the scientific evidence for a favourable effect of supplementing formula or solid food with B. lactis Bb12, is weak and in some cases lacking. There are no studies demonstrating a positive effect of cereals supplemented with B. lactis Bb12 intended for infants and small children. Several health claims related to probiotics have been assessed by EFSA, including claims on reduction of gastro-intestinal discomfort, normal functioning of the alimentary tract, building of the natural intestinal barrier, improvement of the general immunity, mental and cognitive developments of children and immune system of children during growth. In the opinions so far, EFSA has concluded that a cause and effect relationship has not been established between the consumption of the probiotic containing products and the claimed effect. None of the products assessed so far contained B. lactis Bb12 (1 November 2009). Commercially produced cereals are frequent given to infants and small children in Norway from an early age and this is particularly important for the establishment of the intestinal bacterial flora and the development of the intestinal mucosal immune system. According to the notifier, one portion (25gram) of the cereal powder contains 1 x 109 B. lactis Bb12 in monoculture. Taking into consideration that the daily intake is often greater than one portion of cereals, even in infants below 6 months of age, this would represent a daily intake

Almond (Terminalia catappa) seeds are rich in oil; however, their study has received limited attention, with researches focused mainly on their health potentials. The present study assesses the composition of the fatty acid (FA) components present in the almond seed oils extracted using soxhlet apparatus and analysed by 1H-NMR (Proton Nuclear Magnetic Resonance) and Gas Chromatography Mass Spectrometry (GC-MS). Generally, there was significant agreement between the results from the 1H-NMR and GC-MS analyses, however, 1H NMR gave more reliable and reproducible results. The GC-MS and 1H NMR results revealed that the oils contained oleic acid (>18 %), linoleic (>28%) linolenic acid (≤0.03 %) and saturated fatty acids (>44 %).

The GC-MS and 1H NMR results revealed that the oils contained oleic acid (>18 %), linoleic (>28%) linolenic acid (≤0.03 %) and saturated fatty acids (>44 %).","PeriodicalId":11994,"journal":{"name":"European Journal of Nutrition & Food Safety","volume":"247 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88529072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
