Investigating the effect of processing conditions on the content of
glycyrrhizic acid in licorice (Radix et Rhizoma
Glycyrrhizae)
Authors: Truong Minh-Nhut , Tran Quang-Tu , Qua Le Thi , Le Lan-Phuong Thi
Published: April 2024

Licorice is the root of Glycyrrhiza uralensis Fisch or
Glycyrrhizae inflata L. or Glycyrrhiziae
glabra L. It was a familiar medicinal herb in traditional
medicine, which was commonly used in two different forms raw licorice (Sinh
Cam thao) and honey-fried licorice (Chich Cam thao), with completely
different effects. The processing enhanced the impact on the
Spleen and Stomach organs and tonified
Qi but reduced the bioactivities of clearing heat,
antitussive, and detoxifying. The purpose of this study was to propose a
processing method that minimizes the degradation of the main bioactive
compound, glycyrrhizic acid in licorice.

Honey-fired licorice was processed according to the guidance of Circular
30/2017/TT-BYT of the Vietnamese Ministry of Health. The frying conditions
such as frying temperature, honey soaking time, the ratio of honey to
licorice, and the ratio of water to honey were investigated in order. The
content of glycyrrhizic acid was determined according to the process of
Vietnamese Pharmacopoeia V.

Glycyrrhizic acid was least decomposed when processing honey-fired licorice
under the following conditions: the frying temperature of 260°C, the
honey soaking time of 1 hour, the ratio of honey to licorice was 1:10, and
the ratio of water to honey was 1:1.

The content of glycyrrhizic acid in licorice was influenced by the frying
process, in which temperature was the most significant factor. Honey was an
ingredient that altered the effects of licorice in traditional medicine,
however, the presence of honey also contributed to the degradation of
glycyrrhizic acid in this medicinal herb.
Is turning food waste into insect feed an uphill climb? A review of persistent challenges
Authors: Biteau Corentin , Bry-Chevalier Tom , Crummett Dustin , Ryba Ren , St. Jules Michael
Published: April 2024

One major hurdle for our current food system is the enormous amount of food that goes to waste. Insect farming has been proposed as a potential solution, offering one way to turn waste into agricultural resources such as livestock and aquaculture feed. In this article, we review the types of materials currently used to raise insects at commercial scales, and we examine whether those materials compete with conventional animal agriculture or other economic sectors. While the idea of turning trash into treasure for insect agriculture may be appealing in theory, the reality is more challenging. Only some types of insects can be farmed using food waste, while others perform poorly. The inconsistent nature of food waste, in terms of both supply and quality, makes food waste poorly suited for large-scale insect farms that need to produce a consistently high-quality product. This means that insect-farming companies tend to rely on the same high-quality feeds already sought by other industries. Furthermore, competition exists for the types of food waste that could be used by insect agriculture, with agriculture, aquaculture, pet food manufacturing, and biogas production already seeking to use this waste. The types of food waste that can be used in insect farming are limited due to risks that contamination poses to food safety. To truly leverage food waste in insect agriculture, especially considering the dispersed nature of household and municipal waste streams, substantial logistical investments would be required. Overall, turning food waste into insect feed faces a range of persistent challenges that makes the widespread use of insects in addressing food waste an uphill climb.

ENGINEERING PREPARATION OF THE SOIL BASE FOR THE FOUNDATIONS OF THE CONSTRUCTIONS OF THE DERHACHI SOLID WASTE LANDFILL

Published: April 2024

After conducting engineering and geological investigations, it became necessary to provide scientific support for construction in terms of engineering preparation of the soil base for the foundations of the structures due to extreme unsustainability in the plan and depth of the rocks. Such engineering-geological conditions significantly impact the choice of foundation structures and the justification of measures to reduce or eliminate the negative effect on the environment and the development of dangerous geological processes and phenomena. We thoroughly studied the deformation and strength properties of the supporting soil layers and developed recommendations for their engineering preparation and improvement of the indicators. Bulk soil is present in local depressions: construction debris, sand, and compacted loam. Based on the analysis of physical and mechanical properties, we could conclude that this soil cannot be used as a soil base for the foundations of buildings due to its loose composition and enrichment with organic substances and must be completely replaced during the production of earthworks. They can be used as a basis for laying engineering networks.
After excavation pits for individual columns, before setting up the preparation, it is necessary to carefully inspect the soil foundation to ensure that it is the same engineering and geological element specified in the project.
The soil base of the foundations is redeposited subsidence loess loams, which have mostly lost their subsidence properties, but local inclusions with subsidence properties have remained in the thickness of these soils. If there are lenses of soils in the soil base with indicators of physical and mechanical characteristics that are lower than those adopted in the project and that have a thickness of less than one meter, they should be removed and replaced with sand or sand-crushed soil with layer-by-layer compaction and compaction quality control. Doing so will create the same soil conditions for the building foundation.
The performed scientific and technical support of the construction made it possible to choose a method of technical soil reclamation—partial replacement of weak soils with sand and crushed stone, which, after layer-by-layer compaction, can withstand a significant load and stability under vibrational influences.

ASSESSMENT OF THE EFFICIENCY OF FIRE EXTINGUISHING SYSTEMS
Authors: Abramov Yu. , Kolomiiets V. , Sobyna V.
Published: April 2024

As previously shown, many indicators characterise the quality of fire extinguishing systems. The most common quality indicator is fire extinguishing time. For fire extinguishing systems focused on extinguishing Class B fires using sprayed water, the authors have constructed a transcendental equation, the root of which is the fire extinguishing time. We derived the equation provided that the intensity of the sprayed water supply to the combustion centre to be described by the Heaviside function. The dynamic properties of fire are defined using the integral Laplace transform. We obtained the functional dependence of class B fire extinguishing time on fire parameters and showed that this time does not exceed a tenth of the constant fire time. In the first approximation, the inertial properties of the fire extinguishing system can be taken into account by the transfer function of an aperiodic link with a generalised time constant. For this case, we constructed a transcendental equation that determines the fire extinguishing time by the inertial fire extinguishing system. We note that, according to inertial properties, fire extinguishing systems fall into three classes. For each of the three classes, estimates of the extinguishing time of a class B fire were obtained, depending on the dynamic properties of this fire. The results show that this time can change several times. The authors have introduced the criterion for the efficiency of fire extinguishing systems, which characterises the degree of approximation of the speed of the fire extinguishing system to the maximum possible value. This criterion also indicates how much it is necessary to increase the extinguishing agent mass supplied per unit area of the fire relative to the extinguishing agent mass supplied in leaps per unit area of the fire, provided that the extinguishing times are the same. We obtained estimates of the effectiveness of fire extinguishing systems using this criterion. Furthermore, we provided recommendations on the use of the efficiency criterion.

DETERMINING THE RECOVERY TIME OF THE FIRE-SAFE CONDITION OF HYDROGEN STORAGE AND SUPPLY SYSTEMS
Authors: Abramov Yu. , Kryvtsova V. , Mykhailiuk A.
Published: April 2024

The fire prevention system can function in passive or active modes. In active mode, such a system implements a set of measures aimed at restoring the fire-safe state of the hydrogen storage and supply system after it is in a fire-hazardous state. The authors consider variants of its functioning for a highly reliable fire prevention system. The first option has the reliability of the fire inspection, which is equal to one, and the second option has the reliability of the fire inspection, which is different from one. Using graphs of the states of the hydrogen storage and supply system, we constructed systems of Kolmogorov equations and derived expressions for the probabilities of finding this system in the corresponding states. The article shows that the time to restore the fire-safe state of the hydrogen storage and supply system in the first variant should not exceed the probability of its being in a fire-hazardous state, reduced to the unit of the intensity of the transition of this system from a fire-safe state to a fire-hazardous state. In the second option, the time to restore the fire-safe state of the hydrogen storage and supply system increases following the law described by a hyperbola of the first order, the argument of which is the reliability of the fire safety inspection of such a system. We have obtained an expression for the reliability of the functioning of the fire prevention system focused on ensuring the fire safety of hydrogen storage and supply systems. We show that the reliability of the functioning of such a prevention system depends significantly on the reliability of the fire-engineering inspection of the hydrogen storage and supply system. We have also derived an expression for the time to restore the fire-safe state of the hydrogen storage and supply system that is determined a priori by the reliability of the fire prevention system functioning, the reliability of the fire inspection, and the intensity of the transition of the hydrogen storage and supply system from the fire-safe to the fire-hazardous state.

Western Mongolian (Oirat-Kalmyk) loanwords in Kyrgyz
Authors: Alimov Rysbek
Published: April 2024

The Kyrgyz are one of the Turkic peoples that have had extensive contact with Mongolian tribes throughout history, and their language has one of the largest numbers of loanwords of Mongolian origin. Careful analysis shows that these words were borrowed from several historical Mongolian idioms at various times. Western Mongolian loanwords make up the most recent stratum in terms of chronology. They were acquired in the 16th–18th centuries from Western Mongolian idioms, whose living successors are Oirat and Kalmyk. This article is the first attempt to deal specifically with loanwords from Western Mongolian languages to a particular Turkic language.
The author of the paper offers numerous, especially phonological, criteria, for identifying Western Mongolian loanwords in Kyrgyz, and provides examples that meet these criteria.
The fact that Mongolian loanwords from the late period are more prevalent than those from earlier layers, and that they also include examples related to Lamaism, Mongolian culture and ethnography, suggests that the Oirat-Kalmyk and Kyrgyz tribes had more intensive interaction than is often recognized.

Microwave usage and cancer: Do microwaves cause cancer?
Authors: Abd Rahman Muhammad Abdullah Al Azam , A Rahman Zairina
Published: April 2024

Materials containing water, for example foods, fluids or tissues, absorb microwave energy readily, which is then converted into heat. This principle is applied in microwave ovens, an electrical appliance that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. Amidst the hustle and bustle of modern life, the microwave oven has been a great help, as the rapid development of technology keeps consumers in the fast lane. Cancer is defined as the uncontrolled growth and spread of cells. It can affect almost any part of the body. The growths often invade surrounding tissue and can metastasize to distant sites. In this paper, we will explore the function of microwave ovens, the pathophysiology of cancer, and whether is there any evidence of a relationship between microwave ovens and cancer.

Published: April 2024

The utilization of biopolymer derived from Moringa oleifera bark using ZnCl2 and H2SO4 as activating agents for eliminating Methylene blue, Escherichia coli and Pseudomonas aeruginosa from producing wastewater. In this study, Methylene blue and both bacteria were effectively adsorbed by activated carbon with lowest dosage. The activated carbon was prepared from natural-by product of Moringa oleifera bark by pyrolysis in a furnace at 700°C for 1 h. The characteristics of activated carbon have been determined using Scanning Electron Microscopy (SEM), Brunauer-Emmett-Teller (BET), pHzpc (zero point charge), and FTIR spectroscopy. The obtained result were closely fitted with Freundlich isotherm model and adsorption kinetics follow the pseudo-second order model with the highest value of correlation coefficient (R2~1). Adsorption quantity was dose dependent and bacteria were maximum adsorbed using 10 mg of activated carbon as well as 25mg for methylene blue. The maximum adsorption capacity showed within 1 hour. The bacterial load was reduced by 98% for E. coli, 96% for P. aeruginosa as well as methylene blue reduced 94.2% from aqueous solution using batch adsorption methods. Adsorption process controlled by film diffusion mechanism. These result proposed that the activated carbon of Moringa oleifera can be used as a good adsorbent for the removal of Methylene blue, E. coli and P. aeruginosa.
Biogenic Amines as Freshness Indicator in Halal and Non-Halal Slaughtered Chicken Meat Using Chromatographic Approach
Authors: Mohd Yusoff Muhammad Nazmin , Jaffri Muhammad Haziq , Azhari Syaza
Published: April 2024

Biogenic amines are naturally occurring organic bases produced by bacterial decarboxylation of amino acids that have been associated with harmful toxicology effects to humans. The main objective of this work is to investigate the possible role of biogenic amines (BAs) as indicators of spoilage in fresh chicken meat stored at 4°C for 15 days. A reversed-phase high-performance liquid chromatographic method with isocratic elution system is used for the quantification of four biogenic amines (putrescine, histamine, tyramine, cadaverine and spermine as well as spermidine) in chicken meat. Amines were extracted with 5% of trichloroacetic acid (TCA) and derivatised using dansyl chloride. The variation storage time differentiated the chicken meat on the microbiological characteristics. The results obtained shows that histamine, spermidine, tyramine, cadaverine, and putrescine increased slowly while spermine decreased for both chicken breast in halal and non-halal chicken meat. Thus, this BAs could be used as a spoilage index of fresh chicken meat.

Published: April 2024

This is a clinical case describing a hypertensive female patient with a drug-influenced gingival enlargement (DIGE) on the labial and lingual gingivae of the lower anterior dentition. DIGE is attributed to the prolonged use of medications in a susceptible individual. She had undergone non-surgical periodontal therapy prior to surgical intervention for the removal of gingival enlargement (GE) using diode laser therapy. A diode laser is a type of laser widely used in dentistry. This laser therapy is a less invasive technique for the removal of GE. After 6 months of follow-up, no recurrence of GE was observed, and regular supportive periodontal therapy was adopted to sustain the gingival health. The utilization of the diode laser showed excellent predictability and clinical outcomes.
The application of hurdle technology in extending the shelf life and improving the quality of fermented freshwater fish (Pekasam): A Review
Authors: Nadhira Hananiah  , Abdul Rahim Alina
Published: April 2024

Hurdle technology combines several preservation methods to secure the quality of foods by eliminating or controlling the growth of pathogens, making them last longer and, most importantly, safer for consumption. The hurdle approaches used for this Pekasam is microbially derived hurdle and physico-chemical hurdles. Inoculation of starter cultures with amine oxidase (AO) activity like lactic acid bacteria (LAB) in Pekasam is proven to reduce the accumulation of harmful biogenic amines, especially histamine, for up to 59.9%. This review also involves controlling the water activity and pH of Pekasam to a state where it inhibits the growth of microbes. This can be done by adding natural, cheap, and easy to find ingredients like lime juice (Citrus aurantifolia) to the basic Pekasam recipe. The presence of organic acids in the lime juice act as acidulants; it provides a low pH environment for microbes to retard their growth and therefore reduce the total plate count (TPC) whilst enhancing the flavour of Pekasam. However, in a long- ripened Pekasam, only the water activity hurdle is strengthened with time. Hence, a proper amount of salt is needed to sustain and maintain the water activity level below 0.94. The use of affordable herbs and spices with antimicrobial properties such as garlic, ginger and onion can prevent the proliferation of some pathogenic microbes, commonly found in Pekasam; thus, this helps in increasing the stability of the product. This review aims to outline the application of hurdle technology on fermented freshwater fish quality and shelf life. It focuses on recent accessible applications when combined, providing affordable food which helps those underprivileged people, especially during flash floods and other disruptive calamities such as the COVID-19 pandemic.

Published: April 2024

Nowadays, Machine Learning (ML) plays a significant role in the economy, especially in the stock trading strategy. However, there is an inadequate extensive data analysis using various ML methods. Previous findings usually focus on the forecasting stock index or selecting a limited number of stocks with restricted features. Therefore, the contribution of this paper focused on evaluating different supervised learning algorithms, namely Logistic Regression (LR), Support Vector Machine (SVM), and Extreme Gradient Boosting (XGB), on a big dataset from 28 stocks in Bursa Malaysia. By setting their parameter along and using Walk-Forward Analysis (WFA) method, the trading signal was evaluated based on Accuracy Rate, Precision Rate, Recall Rate, and F1 Score. For stock trading strategies in Malaysia in particular, the findings of this study show that SVM has a better performance compared to LR and XGB in time series forecasting. The ML algorithms have values ranging from 53% to 66% for Accuracy Rate (AR), Recall Rate (RR), and F1 Score (F1). In addition, SVM has the highest Precision Rate (PR) of 73% among the ML algorithms.

A field experiment was conducted to assess the effect of different nursery media on performances of Bush mango (Irvingia gabonensis) and African pear (Dacryodes edulis) seedlings. Five nursery media were formulated from topsoil, poultry manure and river sand in the following ratios; 0:3:3, 1:2:3, 1:3:2, 2:3:1 and 3:2:1. The media formulated were analyzed for the physico-chemical properties and seeds of the test crops were sown in each filled polythene bags with the formulated media. The experiment was arranged in a completely randomized design (CRD). The results obtained show significant (P≤0.05) media effects on days to first and 50% seedling emergence and percentage total emergence in Bush mango but non-significant in African pear. Number of days to last seedling emergence was significantly (P≤0.05) influenced by media in African pear leaf number and plant height for 10 weeks were responsive to differences in media in both crops. Media influenced total dry weight only in Bush mango while dry matter distribution pattern varied significantly in African pear. In both crops, percentage total seedling emergence and seedling vigour were better in medium 1:2:3. Therefore, from the results, the differential influence of media on seedling growth as evidence in the study suggested the need for broader evaluation of media for different tropical tree species to identify the most appropriate medium for each species that will ensure better vigorous seedling production for plantation and/or orchard establishment. Also, the results showed significant variation in weed flora composition, comprised of 35 species made up of 14 families. The families of Asteraceae, Gramineae, Amaranthaceae and Acanthaceae were predominant. Annual weed species and broadleaf were predominant.

Published: April 2024

Language-in-education policy in the apartheid era in South Africa reflected a divide-and-rule strategy, which stipulated that each ethnic group was to be taught in its language. Thus, the post-1994 period in South Africa involved a dramatic re-imagination of the country from a racially divided nation to a diverse but united, non-racial nation. This is pertinent to South Africa, a linguistically diverse country whose history of language in education has been shaped by political interests, as well as pedagogical considerations. Against this background, since the impact of cultural diversity on education policy and reforms is a strategically significant issue for us all, this study sought to explore how Grade 4 English First Additional Language (EFAL) teachers incorporate Grade 4 EFAL learners’ linguistic diversity in teaching and learning. For this qualitative study, 10 Grade 4 teachers in 5 primary schools in one district in South Africa were used as respondents. The researcher used one-on-one telephonic interviews to collect data. The results revealed that teachers acknowledge the need to use some approaches to support oral language development. Besides, teachers use a range of strategies, from translanguaging, and code-switching to translation, to encourage learners to use their home languages to develop proficiency in the EFAL. Also, the study has shown that cooperative language learning, which shares some characteristics with communicative language teaching helps learners develop a great liking of EFAL.
