Day By Day

Fats and oils are an essential part of everyday cooking as well as food products development and their purity are a concern since very early in human history. Adulteration of fats and oils is increased day by day throughout the world, a greater extent. Hence an attempt has been taken to review to identify different suitable rapid detection techniques for ensuring food quality and safety. The study was designed on the basis of extensive literature review for collecting relevant scientific evidence from various sources like Google Scholar, PubMed/Medline database, Science direct database, published journal, newspaper and periodicals. Various techniques have been utilized to assess the purity of edible fats and oils but yet they are costly and time-consuming. This study summarized the rapid detection techniques so that a common person can perform at the level of the household so as to have a broad picture of the status of adulteration in his food in case of doubt. Edible fats and oils are reported to be adulterated with other low-price oils. For example, mustard oil adulterated with argemone oil and butter yellow and ghee adulterated with vanaspati ghee. The leading challenges include the lack of market survey, lack of acceptance in the wholesale and retail market because of suspecting its purity, community health problem and decrease in consumer confidence.

Classifying citations according to function has many benefits when it comes to information retrieval tasks, scholarly communication studies, and ranking metric developments. Many citation function classification schemes have been proposed, but most of them have not been systematically designed for an extensive literature-based compilation process. Many schemes were also not evaluated properly before being used for classification experiments utilizing large datasets. This paper aimed to build and evaluate new citation function categories based upon sufficient scientific evidence. A total of 2153 citation sentences were collected from Indonesian journal articles for our dataset. To identify the new categories, a literature survey was conducted, analyses and groupings of category meanings were carried out, and then categories were selected based on the dataset’s characteristics and the purpose of the classification. The evaluation used five criteria: coherence, ease, utility, balance, and coverage. Fleiss’ kappa and automatic classification metrics using machine learning and deep learning algorithms were used to assess the criteria. These methods resulted in five citation function categories. The scheme’s coherence and ease of use were quite good, as indicated by an inter-annotator agreement value of 0.659 and a Long Short-Term Memory (LSTM) F1-score of 0.93. According to the balance and coverage criteria, the scheme still needs to be improved. This research data was limited to journals in food science published in Indonesia. Future research will involve classifying the citation function using a massive dataset collected from various scientific fields and published from some representative countries, as well as applying improved annotation schemes and deep learning methods.

This study was designed to identify the status of shifting (jhum) cultivation and its impact on environment in Rangamati district. A total 55 jhum cultivators were selected on the basis of purposive sampling technique from 5 upazillas of Rangamati district. Data were collected during the period October to December, 2009. The researcher collected information himself using direct and open questionnaire. The study revealed that most of the jhum cultivators were middle age (30-50 years), with illiterate (47.27%) and main occupation possessing jhum cultivation. The present status of agricultural land (hill/slope) of jhumia family in the studied area, about 60% of the respondents have only 1-2 acres of land for jhum cultivation and 25% of the respondents have 2.1-3 acres of land. The use of agro-chemical remains limited in the CHT. This is mainly because of financial constraints, lack of market access, and low requirement of chemical for traditional jhum cultivation. The maximum percentage of irrigation (74.55%) was mainly depended on rainfed in jhum cultivation. On the other hand about 45.55% respondents were responded that their income status were medium through shifting cultivation, 30.90% were responded high. Similarly in the study area it was found that a majority (45.45%) portion of respondents were responded that labour utilization in shifting cultivation was medium. This study also found that the environment was degraded gradually day by day. The maximum respondents (94.55%) had given opinion that deforestation was the major environmental problem created by shifting cultivation, 74.55% respondents had given opinion that shifting cultivation accelerated loss of top soil and 60.00% respondents had given opinion that lost of wild animals was occurring due to shifting cultivation. Biodiversity also degraded mostly. Excluding shifting cultivation there were many reasons of environmental degradation in the study area. Population growth is considered by 90% of the respondents as a major factor causing severe degradation of environment. Indiscriminate forest fire was responsible for environmental degradation. In addition cutting of hill, collection of soil, and extraction of stone, river erosion and land slide as responsible for degradation of environment. The study recommended that new methods must be developed, applied, and tested for sustainable management of jhum cultivation and environmental protection.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14840 J.

In the post-COVID-19 era, virology-related research, which not only depends on the governments as its main source of funding but also requires international and interdisciplinary collaborations, is recognized as an essential defense for sustainability. Few published studies have examined the trend, but only for certain viruses before the mid-2010s. Moreover, it is challenging to define generally accepted virology-related research fields due to its broad spectrum. Thus, it is time that we confront the unprecedented pandemic to understand the status of nationally supported projects in developed nations to establish international collaborative research strategies from an interdisciplinary perspective. In this study, 32,365 national-funded projects were collected from the US, EU, and Japan and assigned to five scientific fields to conduct a cluster analysis. Then, an expert-based approach was utilized to define an individual cluster. Moreover, a comparative analysis between nations was carried out to determine if there was a competitive edge for collaboration. As a result, a framework for virology-related research areas was constructed to provide the status quo and differences between nations’ research capabilities, thereby eliciting practical global research and development (R&D) cooperation to achieve a common agenda and a direction for goals in the post-COVID-19 era. These findings have implications for viral response R&D, policy, and practice for future pandemics. A systematic approach based on scientific evidence and an R&D collaboration strategy between industry and academia is essential to resolve the interdisciplinary barriers between countries and promote sustainable virus R&D collaboration.

Potential Biomarkers

Malaria has been responsible for the highest mortality in most malaria endemic countries. Even after decades of malaria control campaigns, it still persists as a disease of high mortality due to improper diagnosis and rapidly evolving drug resistant malarial parasites. For efficient and economical malaria management, WHO recommends that all malaria suspected patients should receive proper diagnosis before administering drugs. It is thus imperative to develop fast, economical, and accurate techniques for diagnosis of malaria. In this regard an in-depth knowledge on malaria biomarkers is important to identify an appropriate biorecognition element and utilize it prudently to develop a reliable detection technique for diagnosis of the disease. Among the various biomarkers, plasmodial lactate dehydrogenase and histidine-rich protein II (HRP II) have received increasing attention for developing rapid and reliable detection techniques for malaria. The widely used rapid detection tests (RDTs) for malaria succumb to many drawbacks which promotes exploration of more efficient economical detection techniques. This paper provides an overview on the current status of malaria biomarkers, along with their potential utilization for developing different malaria diagnostic techniques and advanced biosensors.
