Authors: Chronopoulou Maria-Ioanna , Fokides Emmanuel
Published: September 2021

The study presents results from the use of a 3D simulation for teaching functional skills to students with learning, attentional, behavioral, and emotional disabilities, attending regular schools. An A-B single-subject study design was applied. The participating students (eight eight-to-nine years old) explored the simulation (a virtual school), encountered situations in which they observed how they are expected to behave, and had to demonstrate what they have learned. Each student attended a total of four two-hour sessions. Data were collected by means of observations and semi-structured interviews. All students demonstrated improved functional skills both in terms of the number of behaviors they acquired and in terms of those that were retained and manifested in the real school environment. On the basis of the results, it can be argued that 3D simulations are a promising tool for teaching functional skills to students with disabilities.

Authors: Muñoz-Arteaga Jaime
Published: September 2021

Reading is an important competency to be developed for children in the first years of elementary school. Reading becomes a mechanism that allows the children to interact with the world and identify their characteristics. Dyslexia is one learning disability frequently manifested in elementary school, and to identify it, teachers require extra educative resources, in particular educational applications. This work proposes a process model to design and develop educational applications considering the learning needs of children with dyslexia. It involves a user-centered approach because different perceptions of several actors are considered. The performance of the proposed model is explored in a case study and an evaluation, taking into account usability and accessibility factors.
Attitude of General Public, Family Members, and Health Professionals Towards People With Intellectual Disabilities (PWID)
Authors: Hazarika Mythili , Choudhury Sandamita
Published: September 2021

Attitude defines one's behavior towards the people with intellectual disability (PWID). History on PWID indicates influence of psycho-social, biological, religious, and educational factors for the existence of stereotypical attitudes. But since the early part of the 21st century efforts have been reported across countries in integrating the PWID in the community at large. Families of PWID undergo high levels of stress and emotional reactions which call for intervention. Families often adopt strategies to hide the existence of a disability, which delays the treatment and rehabilitation of PWID. Also, stakeholder attitudes towards them highly influences their rehabilitation and integration in the mainstream society. Hence, this chapter is an attempt to focus on the importance of attitude towards individuals with intellectual disability by general public, family members, teachers, students, employers, and health professionals and its implications and further recommendations for the betterment of their condition.

It has a significant role in interpersonal and couple's relationships. The sexuality of people with intellectual disability is important from the view of medical, pedagogical, psychological, and ethical aspects. As intellectually disabled person approach puberty their control of behavior and expression of sexuality may manifest in unacceptable ways. They are also at increased risk for physical, sexual, and emotional abuse. The chapter focused on the sexuality, the risk of sexual abuse, marriage, partner violence among people with intellectual disability. The requirement of sex education and components of sex education for various age ranges were also explained and effectiveness of such programs were also discussed. The chapter also discussed the parenting and challenges involved in parenting among intellectually disabled individuals.
Tourism Promotion and Disability
Authors: Gandin Stefania
Published: September 2021

This study illustrates the preliminary results of a corpus-based analysis aimed at discovering the main linguistic features characterising the promotion of tourism for special-needs travellers. Even if accessible tourism represents an important sector in the market, not only for its social and moral importance but also for its strong economic potential, detailed research on the linguistic properties of tourism for disabled people is still rather limited and mainly tends to focus on the problems of physical access rather than considering the ways to improve its promotional strategies. Through a comparative corpus-based analysis, this paper will investigate the relevant linguistic features of a corpus of promotional materials advertising holidays and tourist services for the disabled, and relate them to the communicative strategies of two other corpora dedicated to the standard and translational language of tourism. The aim of this research is to show how mainstream tourism discourse still considers disability as a taboo topic, mostly ignoring or vaguely mentioning it in the general promotion of tourist destinations. The study will also attempt to suggest new linguistic and social attitudes aimed at stylistically improving and further including the accessible tourism sector within the overall tourism promotion.

Fuzzy Logic Theory and Applications in Uncertainty Management of Linguistic Evaluations for Students
Authors: Solo Ashu M. G. , Gupta Madan M.
Published: September 2021

Fuzzy logic can deal with information arising from perception and cognition that is uncertain, imprecise, vague, partially true, or without sharp boundaries. Fuzzy logic can be used for assigning linguistic grades and for decision making and data mining with those linguistic grades by teachers, instructors, and professors. Many aspects of fuzzy logic including fuzzy sets, linguistic variables, fuzzy rules, fuzzy math, fuzzy database queries, computational theory of perceptions, and computing with words are useful in uncertainty management of linguistic evaluations for students. This chapter provides many examples of this after describing the theory of fuzzy logic.

Authors: Sood Rohit
Published: September 2021

The traditional trade and business are increasingly getting tough competition from e-commerce. E-commerce has reached most of the consumers in the urban sector and the youth, but the challenge lies in front of the companies so that it reaches the rural sector and the aged people. The rural population of India has to go to nearby cities to purchase luxury products. E-commerce can widen its area of operations and come to their help. Also, thanks to Jio, the people aged more than 45 and the retired are increasingly getting digital in the urban areas. Many of them still purchase the old-fashioned way, but they may adapt to e-commerce as they are adopting the digital world. Here, e-commerce can get new market segment without changing much in their logistics. A thing that is critical within the digital marketplace is the profound understanding of people, their behavior, and their community.

Authors: Annaç Göv Sabiha
Published: September 2021

The aim of the study is to reveal Gaziantep Airport qualifications by applying the SWOT method. Qualitative research method was used in this study. SWOT analysis of Gaziantep Airport has been done. According to the results, although the airport has significant strengths and opportunities, it has some weaknesses and threats. The usability of the cargo terminal, having more destinations, being an international airport are determined as the strong dimensions of the airport. The insufficiency of the passenger terminal and parking area, the inefficiency of the instrument landing system were determined to be the weakness of the airport. However, investments made to overcome these deficiencies can be considered as opportunities. In addition, population growth, tourism potential due to the city of gastronomy, and the increase in the trade volume of the city have been identified as the opportunities of the airport. The proximity of the airport to the Syrian border, where the war has been going on since 2011, can be seen as a threat.

Authors: Gui Haixia , Zhao Banglei , Li Huizong , Che Wanliu
Published: September 2021

Overlapping coalition formation is a very active research field in multi-agent systems (MAS). In overlapping coalition, each agent can participate in different coalitions corresponding to multiple tasks at the same time. As each agent has limited resources, resource conflicts will occur. In order to resolve resource conflicts, we develop an improved encoding revision algorithm in this paper which can revise an invalid two-dimensional binary encoding into a valid one by checking the encoding for each row. To verify the effectiveness of the algorithm, differential evolution was used as the experimental platform and compared with Zhang et al. The experimental results show that the algorithm in this paper is superior to Zhang et al. in both solution quality and encoding revision time.
A Novel Machine Learning-Based Approach for Outlier Detection in Smart Healthcare Sensor Clouds
Authors: Dwivedi Rajendra Kumar , Kumar Rakesh , Buyya Rajkumar
Published: September 2021

A smart healthcare sensor cloud is an amalgamation of the body sensor networks and the cloud that facilitates the early diagnosis of diseases and the real-time monitoring of patients. Sensitive data of the patients which are stored in the cloud must be free from outliers that may be caused by malfunctioned hardware or the intruders. This paper presents a machine learning-based scheme for outlier detection in smart healthcare sensor clouds. The proposed scheme is a hybrid of clustering and classification techniques in which a two-level framework is devised to identify the outliers precisely. At the first level, a density-based scheme is used for clustering while at the second level, a Gaussian distribution-based approach is used for classification. This scheme is implemented in Python and compared with a clustering-based approach (Mean Shift) and a classification-based approach (Support Vector Machine) on two different standard datasets. The proposed scheme is evaluated on various performance metrics. Results demonstrate the superiority of the proposed scheme over the existing ones.
Chronic Patients' Emotions Toward Self-Managing Care IT
Authors: Savoli Azadeh , Bhatt Mamta
Published: September 2021

Patients’ emotions toward health IT can play an important role in explaining their usage of it. One form of health IT is self-managing care IT, such as activity trackers that can be used by chronic patients to adopt a healthy lifestyle. The goal of this study is to understand the factors that influence the arousal of emotions in chronic patients while using these tools. Past studies, in general, tend to emphasize how IT shapes emotions, underplaying the role of the individual user’s identity and, specifically, how central health is to the user’s self in shaping emotions. In this research, the authors argue that patients’ health identity centrality (i.e., the extent to which they consider health as central to their sense of self) can play an important role in forming their dependence on health IT by affecting their use of it directly and shaping their emotions around it.
Short and Long Term Determinants of Bank Credit Growth in Sri Lanka
Authors: Dharmadasa P. D. C. S.
Published: September 2021

The Purpose: The aim of this paper is to identify the determinants of credit growth of commercial banks in Sri Lanka during the period from 2008 to 2019. Design/ methodology/approaches: The analysis consists of macro-level data collected from monthly basis including bank-specific, macroeconomic, and monetary policy variables that affect credit growth. Co-integration test is conducted using Autoregressive Distributed Lag (ARDL) approach to determine the long-term determinants of credit growth. Findings: The results revealed that growth of money supply, non-performing loan ratio, lending rate, and inflation rate and efficiency ratio have a strong link with credit growth compared to other bank-specific variables, and therefore they can be considered as long term determinants of commercial banks’ credit growth in Sri Lanka. The findings further revealed that growth of GDP and credit growth tend to have a relationship which supports the ‘demand following’ hypothesis of finance-growth theory. All other bank specific variables indicated marginal impact on the credit growth in the short-run. Policy implications: The results suggested that the government should prioritize all growth promoting policies, because, low economic growth disturbs aggregate demand in the country. To achieve a desired growth, continuation of expansionary monetary and fiscal policies is necessary with a close coordination between them. Continuation of the monetary targeting framework of the CBSL is also necessary since money supply growth influences credit growth in the country. Originality: This research is expected to be a pioneering work in the field as studies focusing especially on credit growth are relatively limited in the Sri Lankan setting.

Authors: Malthouse Theo , Rudd Ian , Down Chris , Moore James
Published: September 2021

There has been an increasing interest in mesh-free surgical options for Stress Urinary Incontinence (SUI). Traditionally rectus fascia autologous slings were placed at the bladder neck but more recently they are positioned at the mid-urethra (aMUS). The long-term outcomes for these patients are described. A retrospective analysis of aMUS patients between 2009-2014 by a single surgeon for primary SUI was performed. All patients were evaluated preoperatively with urodynamics. Patient reported outcomes were collected via postal questionnaire using the ICIQ-UI short-form questionnaire, 7-point Global Impression of Improvement score, questions on pad usage, self-catheterisation, overactive bladder treatment and re-operation rates. Results included 31 patients (response rate 63.8%). The median age was 49 years and median BMI was 27. Twenty-seven per cent (27%) of patients had stress predominant mixed urinary incontinence pre-operatively. Median length of follow up was 8 years (5- 11); 60% of patients were dry and pad-free. Seventy-seven per cent (77%) found the surgery led to “much improvement” or “very much improvement” in quality of life. Thirteen per cent (13%) of patients reported a deterioration in quality of life. The median ICIQ-UI short form score was 5.5. 16.7% were taking medication and 1 patient received botulinum toxin therapy for overactive bladder symptoms. All these patients had mixed urinary incontinence on preoperative urodynamics. The re-operation rate was 13.3%. One patient was selfcatheterising. Three out of 31 (10%) had experienced pelvic pain, with 2 out of 31 (6%) experiencing dyspareunia. AMUS shows good long-term continence outcomes and is associated with low rates of de-novo overactive bladder symptoms and voiding dysfunction.

Authors: Shah Sagar Jatish , Kulkarni Gaurav , Ramachandran Naren , Chandrasekhar Padmini , Podar Rajesh Satyanarain , Singh Shishir
Published: September 2021

Background:

Cone beam computed tomography (CBCT) is a three-dimensional digital imaging which provides an image that can be viewed in multiple planes thus providing a better understanding of the anatomy of the root canal. Aim: This study aimed to evaluate the endodontic treatment quality of root-filled teeth and to determine the relationship between endodontic technical errors and complications.

Materials and Methods:

One hundred and fifty-two root canals were evaluated by CBCT from December 2017 to January 2019. Three endodontists assessed the root canals for the presence of technical errors and treatment complications using the periapical and endodontic status scale. Chi-square test and descriptive analyses were performed.

Results:

Sixty-one (40.4%) root canals had periapical radiolucency followed by 45 (29.8%) root canals with short obturations. Sixty-nine root canals (45.7%) and 45 (29.8%) root canals had nonhomogenous root canal filling and coronal seal (CS), respectively. Statistically significant association was seen with the length of the root canal filling, homogeneity, CS, and complications (P < 0.05).

Conclusions:

There was high prevalence of apical radiolucency in root-filled teeth. The presence of short obturations, poor CS, and nonhomogenous obturation led to higher prevalence of endodontic complications.

Published: September 2021

The Nigeria ports plays a vital role in socio-economic growth by being a cheap mode of conveying shipments for importation and  exportation. The number of vessels coming into the Nigerian ports every year is on the average of about 4,900. A well flourishing and efficient ports and cargo management will in no doubt put a developing economy such as Nigeria in a leading pedestal with developed nations. Thus, stakeholders in container terminals are concerned about discharging containers as fast as possible, with the purpose of saving terminal costs. This study is driven to minimize the time being used up by ships in container terminal using genetic algorithm (GA) and thus attain maximum efficiency. The limited berth space in the wharf lead to berth allocation problem (BAP) and an optimal solution is required. Moreover, high berth occupancy results in congestion where vessels are queuing to be served. This leads to high turn-around time and results in bad service for the container terminal. The aim of this study is to develop and implement a genetic algorithm based model for berth allocation (i.e. GAMBA) with the view to minimize the total delay times of vessels at container terminals. A study of the operations in Apapa wharf was done with the view to understand the berth allocation process vis-à-vis the challenges therein. The relevant parameters required for berth allocation were identified and GAMBA was developed using the identified parameters. GAMBA was  implemented using real life data collected from the container terminal, Apapa, Lagos, Nigeria. The results showed that increasing the quay length by 250m has a very similar outcome on the container port’s efficiency as reducing the proportion of increasing handling time by 0.0025 h/m. This revealed that the outcome on the container port’s efficiency by increasing the quayside length was the same as reducing the proportion of increasing management time. Based on these results, the optimized allocation of container storage and the automation of the handling process can be proposed as cheaper alternatives to construction and development of the containers port in relation to increasing the productivity of the port.

Published: September 2021

While the development of information systems in workplaces with the aim of achieving cost-effectiveness, efficiency and quality of service delivery remain sacrosanct, issues of effective utilization and its resultant implications on organizational performance remain critical from one context to another. Unfortunately, few studies had considered focusing on these causal relationships among information system deployments in the construction industry especially in developing countries like Nigeria. This work modelled the interactions causal relationships associated with task technology fit, system usage and performance variables using the TUSPEM model. Through convenience and stratified sampling techniques, the views of 136 senior staff including top level management staff, sectional heads and other senior staff of a construction firm in Nigeria were sought. Smart PLS structural equation modeling software was used for the analysis of the dataset. The result showed significant relationships between causal variables in the TUSPEM model such as Application utilization to performance (t-value 2.44, P< 0.02), utilization to user satisfaction (t-value 2.87, P< 0.01). TTF to performance (t-value 2.86, P< 0.06), satisfaction (t-value 4.40, P< 0.00), User attitude to utilization (t-value 5.40, P< 0.00). Computer 2self-efficacy to utilization (t-value 4.47, P< 0.00). User satisfaction to performance (t-value 2.47, P< 0.01). Critical appraisal and integration of quality feedback on information system usage and its resultant effects on the numerous information systems being deployed must not be sideline if the sustainability of information system is anything to go by. Other implications are discussed.

Published: September 2021

Identity management concerns transcends technical design issues as users disposition, awareness and attitude play a vital role in the effectiveness of such systems. A framework that supported some important digital identity management system security related features was presented in a previous study. In this current study, an attempt to empirically demonstrate the functioning of these features and to access how user’s awareness, disposition and attitude impact on the proper functioning of such systems was undertaken. To achieve these, a system was modeled and implemented using object oriented analysis and design method. The developed system empirically generates forensic evidence and an implicit mutual authentication scheme. The resulting system developed was tested for these features. The results obtained showed that the framework did provide for reliable forensic evidence generation and it also provided for the implementation of an implicit form of mutual authentication scheme. However, the outcome of a brief test conducted to gauge the reliability of this implicit mutual authentication scheme showed that the support provided was not very reliable based on these users’ factors (awareness, attitude and deposition)

Published: September 2021

The Random Early Detection (RED) algorithm has not been successful in keeping the average queue size low. In this paper, we an improved RED-based algorithm called QLRED which divides the dropping probability function of the RED algorithm into two equal segments. The first segment utilises a quadratic packet dropping function while the second segment deploys a linear packet dropping function respectively so as to distinguish between light and high traffic loads. The ns-3 simulation performance evaluations clearly showed that QLRED algorithm effectively controls the average queue size under various network conditions resulting in a low delay. Replacing/upgrading the RED algorithm in Internet routers requires minimal effort since only the packet dropping probability profile needs to be adjusted.

Published: September 2021

The advent of the internet with its attendant democratization of data and deluge of information had given rise to the avalanche of news media agencies. These agencies publish news articles with varying emotional reports especially stories conveying bad sentiments to the public. As major news agencies operate micro-blogging websites and establish their presence on social media channels, the distribution of bad news increases. It has been shown that constant exposure to bad news presented in a body of texts, graphics, and videos/audios contribute to increase in high blood pressure, anxiety attacks, bowel disorders, stroke and/or heart failure. In this work, we presented a sentiment analysis framework to extract news articles from FrontPage of online newspapers and generate contextual wordlists to support positive news broadcasting. Using a set of 12 Nigerian online news channels, we employed a hybrid method of dictionary and corpus-based lexicon approaches to achieve the wordlist derivation. The result advocates for an alternative way of reporting negative news to reduce the adverse impact it has on the masses.

The objective was to evaluate the effect of increasing the dietary inclusion of spineless cactus (Nopalea cochenillifera Salm Dyck) on the carcass characteristics and meat quality of confined lambs. Thirty-two male Santa Inês lambs with an average age of 140 days and an initial body weight of 20.4 ± 2.60 kg were used in this study. The lambs were housed in individual stalls for 70 days and individually fed a ration with spineless cactus included at 0, 241, 519, or 753 g/kg of dry matter (DM). The lambs were slaughtered, and characteristics of the carcass and meat were recorded and analysed. Inclusion of spineless cactus had a quadratic effect on the bodyweight at slaughter and on the empty bodyweight of the lambs. The inclusion of 500 g/kg of spineless cactus provided the highest predicted cold carcass weight (16.03 kg). There was a quadratic effect of the inclusion of spineless cactus on the weight of meat cuts and leg composition of lambs. The inclusion of spineless cactus did not influence pH, tenderness, and water-retention capacity of the meat. However, the intramuscular fat content increased 1 mg for every 10 g/kg inclusion of spineless cactus in the diet. Quadratic effects were observed of the inclusion of spineless cactus on the weights of the liver, heart, rumen, blood, skin and internal fat of the lambs. Up to 500 g/kg of spineless cactus could be included in the diet of confined lambs.

Published: September 2021

The goal of this research was to evaluate the nutritive value of full-fat de-hulled sunflower seeds (DHSS) in feeding broiler chickens. Three experiments were conducted. Experiment 1 determined the proximal analysis of DHSS, the essential amino acid content, and apparent metabolizable energy (AME). In experiment 2, two diets were formulated, namely a control and a diet containing 10% DHSS. Apparent ileal digestibility (AID) of dry matter (DM), crude protein (CP), and ether extract (EE) were calculated. In experiment 3, the performances of broilers fed the two diets were evaluated in terms of the relative weights of digestive system organs, breast meat colour, growth and feed consumption. Full-fat de-hulled sunflower seeds were characterized as having 507.9 g/kg EE, 282.1 g/kg CP, 21.02 MJ/kg AME and 9.3 g/16 g N arginine. Apparent ileal digestibility of DM in the 10% DHSS diet was 658.0 g/kg, similar to that of the control diet (643.0 g/kg). Partial substitution of DHSS for soybean meal (SBM) did not affect the relative weight of digestive system organs, except for the liver. The relative weights of the liver were 17.90 g/kg bodyweight in birds fed the DHSS diet and 16.37 g/kg bodyweight (P <0.05) in the control. The colour of the breast meat was 3.5% darker and 13.8% less yellow for DHSS birds compared with the control. Growth and feed consumption were unaffected by the dietary treatments. Therefore, 10% DHSS can partially replace SBM in broiler finisher diets.

This study evaluated the effects of sodium hydroxide (NaOH) treatment on the nutritional value of Arundo donax (A. donax). Its ultimate goal was to develop an environmentally friendly animal feed alternative that could be produced sustainably while combatting the spread of A. donax. Plants were collected and dried at 60 °C in an oven with controlled air circulation to determine the dry matter (DM) content. The dry plant material was then sprinkled with an NaOH solution of 2%, 4%, 6%, or 8% and placed in leak-proof containers for four weeks. The chemical and in vitro digestibility properties of treated and untreated A. donax samples were analysed in triplicate. The treatment led to significant decreases in neutral detergent fibre (NDF) from 81.06% DM to 69.39% DM, acid detergent fibre (ADF) from 46.99% DM to 43.19% DM, and ether extract (EE) from 2.06% DM to 1.39% DM, in the untreated samples compared with those treated with 8% NaOH, respectively. In addition, DM digestibility increased from 24.61% to 33.78%, ash content from 11.75% DM to 19.92% DM, and ADL from 7.43% M to 15.38% DM. Thus, treatment of A. donax with an 8% solution of NaOH concentration improved its nutritional value.

A meta-analysis was conducted to examine the effect of supplementing the diet of broiler chickens with propolis on growth, bacterial population of the intestine, antiviral serum concentration, intestinal morphology, and digestive enzyme activities in broiler chickens. Forty peer-reviewed articles that had been published between 2003 and 2019 were identified using the PRISMA protocol and included in the study. Data were analysed with mixed model methodology, in which the studies were considered random effects, whereas the level of supplemental propolis was considered a fixed effect. Responses to propolis supplementation in bodyweight (BW) and average daily gain (ADG) were quadratic, but average daily feed intake (ADFI) was not affected. Propolis supplementation improved feed conversion ratio (FCR) significantly as a linear function of the level of supplement. The optimum level of supplementation was between 256 and 262 mg/kg feed and produced maximum ADG and final BW. There was a tendency for mortality to decrease because of propolis supplementation. Propolis had no detectable effect on serum antiviral concentration, intestinal bacterial population or intestinal morphology. Among digestive enzymes, only sucrase increased linearly as propolis was increased. Thus, supplementation with propolis increased the growth performance of broiler chickens positively and the effect was dose dependent. This may have been partly because of an improvement in sucrase activity and other factors related to the nutritional content of propolis. Future study to evaluate specific bioactive compounds of propolis is therefore warranted.

Nấm Pythium vexans là một trong những tác nhân lớn gây ra bệnh thối rễ và ức chế cây rau phát triển. Hiện nay, nghiên cứu ứng dụng chế phẩm sinh học trong kiểm soát, phòng trừ nấm gây hại đang ngày càng được quan tâm trong chiến lược phát triển một nền nông nghiệp sạch và bền vững. Nhiều loài xạ khuẩn thuộc chi Streptomyces được đánh giá là an toàn cho con người cũng như cây trồng, có khả năng ức chế sự phát triển của nhiều loại nấm gây bệnh ở cây trồng nhờ tiết ra một số hoạt chất sinh học. Trong nghiên cứu này, chúng tôi đã phân lập được 20 chủng xạ khuẩn từ 15 mẫu đất tại các vườn trồng rau ở tỉnh Lâm Đồng. Trong đó, chủng Streptomyces LD5.4 được đánh giá có hiệu quả ức chế cao nhất đối với nấm Pythium vexans (51.80%), sau 48h bằng phương pháp khuếch tán đĩa trên môi trường Potato Dextrose Agar (PDA) ở nhiệt độ phòng. Dựa trên đặc điểm hình thái và trình tự 16S rRNA, chủng xạ khuẩn LD5.4 được xác định thuộc loài Streptomyces filamentosus. Với những đặc tính này, chủng Streptomyces filamentosus LD5.4 có tiềm năng ứng dụng vào sản xuất chế phẩm sinh học ức chế bệnh thối rễ trên rau ăn lá họ thập tự do nấm Pythium vexans gây ra.

Streptococcus agalactiae (GBS) là tác nhân truyền nhiễm hàng đầu gây nhiễm trùng huyết sơ sinh giai đoạn sớm. Tầm soát GBS và tiêm kháng sinh dự phòng ở phụ nữ thai sản có thể giúp ngăn chặn hữu hiệu tỷ lệ nhiễm GBS ở trẻ sơ sinh. Phương pháp truyền thống phát hiện và nuôi cấy GBS trên đĩa thạch máu rất tốn thời gian, công sức và độ nhạy thấp. Nghiên cứu này tiến hành tối ưu hóa phản ứng realtime PCR với cặp mồi và mẫu dò được thiết kế nhằm phát hiện gen đặc hiệu cfb của GBS. Các thí nghiệm tối ưu hóa được thực hiện trên chủng S. agalactiae ATCC 13813. Độ đặc hiệu của quy trình tối ưu được kiểm tra trên DNA của chủng Staphylococcus aureus ATCC 25923, Gardnerella vaginalis và Chlamydia trachomatis. Ngoài ra, quy trình tối ưu được thử nghiệm trên 30 mẫu dịch phết âm đạo-trực tràng của phụ nữ mang thai trong giai đoạn 35-37 tuần. Quy trình tối ưu đặc hiệu với chủng GBS, có độ nhạy 50 bản sao/phản ứng, độ chính xác 99.94%, và hiệu quả khuếch đại EA% = 94.5%. Trong số 30 mẫu thử nghiệm, 10 mẫu được phát hiện là có hiện diện của GBS, trong khi nuôi cấy truyền thống chỉ phát hiện 08 mẫu có GBS.

Mục tiêu của nghiên cứu này là khảo sát ảnh hưởng của nhiệt độ nhiệt phân đến đặc tính hóa lý của than sinh học từ trấu nhằm ứng dụng trong lĩnh vực công nghệ sinh học môi trường như làm chất mang trong sản xuất chế phẩm vi sinh và vật liệu lọc thân thiện với môi trường trong xử lý nước thải. Sử dụng các phương pháp phân tích thường quy, phân tích vật liệu (SEM, FTIR, XRD, BET) để đánh giá tính chất than sinh học từ trấu trong khoảng nhiệt phân từ 350-650°C. Khối lượng riêng, pH, EC, khả năng giữ nước và độ tro của than sinh học có xu hướng tăng khi nhiệt độ nhiệt phân tăng trong khi đó hiệu suất tạo than có xu hướng giảm mạnh. Kết quả phân tích cho thấy than sinh học sau khi nung ở 550°C có diện tích bề mặt riêng là 42.22m2/g. Thành phần nguyên tố chủ yếu là C (10.19%), O (52.74%) và Si (36.16%). Kết quả phân tích phổ kế hồng ngoại biến đổi Fourier (FTIR) cho thấy trên bề mặt than sinh học tồn tại liên kết O–H (tần số 3,443.88cm‒1), –CH3 (tần số 2.360cm‒1), –C=O hoặc C=C (tần số 1,600-1,650cm‒1), điểm điện tích không của than ở pHPZC 6.8. Giản đồ nhiễu xạ tia X thấy than sinh học từ trấu có dạng carbon vô định hình khi nung ở 55°C.

Gypsies of the Belarusian Provinces and Land Management Policy at the turn of the 1830s-1840s
Authors: Shaidurov Vladimir N.
Published: September 2021

At the turn of the 18th-19th centuries, the tsarist government in Russia faced the Gypsy question in the context of implementation of the society homogenization policy. There were campaigns initiated to fight with Gypsy vagrancyduring the 1770s-1810s, the primary target of which was to modernize the Gypsies of the Russian Empire and turn them into a constant component of rural or urban societies. However, despite the repressive tools included, these measures did not effect the desired result. The purpose of the present paper is to study the relationship between the Belarusian Gypsies and the authorities when it came to acquisition of land and set up of arable farms in the late 1830s-early 1840s as part of implementation of the subsequent campaign to turn the Gypsies of Russia into a settled population. The basis of the research were archival materials from the fund of the Second Department of the Ministry of State Property of the Russian State Historical Archive (St. Petersburg). Studying of various historical sources revealed the features of implementation of the decree of Nicholas I (1839) in the Belarusian provinces. Despite the willingness of the local gypsy camps to adopt the sedentary life, they faced various forms of latent chauvinism at the local level: officials sabotaged orders from St. Petersburg; peasants did not want to accept Gypsies into their societies. The article is intended for specialists in the history of the Roma and the national politics in the Russian Empire.
We Will Feed Our and a New World: Several Cases of Food Ways of Frontier Regions. Part 2
Authors: Yakushenkov Serguey N.
Published: September 2021

This article is the second part of the study of regional foodways. If the first part is devoted to the analysis of the foodscape of Astrakhan, the second part analyzes the food system of the Republic of Peru. The choice of this object of study is based on the frontier nature of the region, the diversity of economic and cultural types, and hybridity. All these factors allow us to compare the ways of formation of the foodways of these regions.

The Peruvian alimentary landscape began to form in the 16th century, after the conquest of Peru by the Spanish conquistadors. As a result of mutual influences and struggles between elements of autochthonous and alien cultures, a new "hybrid" phenomenon takes shape. The turning point in the development of national cuisine was in the 1930s, when, as a result of gastropolitical strategies, the government managed to create a food system accessible to the workers of large cities. The opening of “people's restaurants” allowed workers to have calorie-dense food. It also contributed to the creation of a national food system.

The search for national identity among the Peruvian elite led to the “discovery” of their national roots. The fact that Peruvian culture was based on natural and ethnic diversity made the country's alimentary system diverse and rich. This process coincided with global trends in the approach to food in the sense of a focus on “simple” and “healthy” peasant foods, as opposed to foods undergone of maximum processing. Ultimately, this was manifested in the creation of a “new Andean cuisine” that embraced Peru's centuries-old traditions and the country's natural diversity. In doing so, Peruvian restaurateurs used both familiar approaches to business and invented new ones that went beyond the culinary arts. As a result of the efforts of many culinary masters and restaurateurs, in competition with internationally renowned culinary brands, a new global culinary brand has been created, recognized around the world.
