Adat as Strategy for Legal Struggle and Legal Mobilization
Authors: Arizona Yance ,   Universitas Gajah Mada
Published: May 2023

The word "adat" has several different meanings in Indonesia. Adat can be used to describe informal dispute settlement procedures, a habit that keeps repeating itself, or a norm that develops into a code of behavior. Adat is perceived in this article as a narrative and a strategy employed by oppressed groups to fight against various forms of exclusion, particularly in relation to land grabbing for resource extraction and conservation carried out by the state and private sectors. This article will analyze the evolution and distinctions of Adat-based studies and movements in Indonesia during the colonial and national periods. Using existing secondary material from various studies on indigenous studies and movements, this article shows the differences in agendas, strategies and actors that use adat in legal discourse and legal mobilization over time. The connection between local, national, and international contexts will also be covered in this study, along with how rural communities dealing with agrarian issues have turned to adat as a strategy for legal mobilization.
AFRICAN INDIGENOUS PHILOSOPHICAL FOUNDATIONS AND ETHICS: A DECONSTRUCTION AND RECONSTRUCTION OF KENYAN EDUCATION SYSTEM
Authors: Mwanzia Ruth M
Published: May 2023

One of the objectives of education is to promote ethical behaviour among learners. This is emphasized by various commissions and reports on education. Despite the enormous investment in education over the years and the high academic qualification, the level of impunity, corruption and intolerance among graduates and other leavers has become a major concern among educationists and stakeholders. Efforts through reforms and commissions have not yielded much in developing ethics among learners. This raises concern on the influence of African indigenous philosophical foundations on ethics. The current study aimed at determining the influence of deconstruction and reconstruction of African indigenous philosophical foundations on ethics among learners in all levels of education. The study was carried out in Kenyan universities and communities. Descriptive survey and correlation research design were adopted for the study. A sample size of 384 respondents comprising of 324 students and 60 academic staff participated in the study. Data collection was done using questionnaires and interviews. Instrument validity was enhanced through expert judgement by supervisors. Reliability of instruments was estimated by use of Cronbach Alpha. Descriptive statistics and inferential statistics were used to analyze the data. Research hypothesis was tested using regression and correlation analysis at a significance level of α = 0.05. The study found out that the African indigenous philosophical foundations contribute significantly towards ethics. The null hypothesis that there exists no significant influence on deconstruction and reconstruction of philosophical foundations on ethics is not supported in the current study. The study recommends the need to integrate the African indigenous philosophical foundations in order to influence ethics among learners in all the levels of education.

Published: May 2023

Background: Metabolic stress is one of the risk factors of lead-induced functional abnormalities of the tissue. The present study aimsat determining the effect of lead on certain energy metabolic profiles in renal tissue of mice.Method: Swiss albino mice were exposed to Pb by gavages at a 5mg/kg body weight dose for 30 days. After treatment, urinary glucose,glucose 6-phosphatase, lactate dehydrogenase, TCA cycle enzymes, different proteolytic enzyme activities, total, acidic, basic and neutralproteins, protein carbonyl content, glyceraldehyde 3-phosphate dehydrogenase activity, tissue Pb deposition and renal morphologywere examined.Results: Lead exposure resulted in glycosuria and decreased glucose 6-phosphatase activity in the kidney, whereas the lactatedehydrogenase activity was increased in that tissue. The malate dehydrogenase and succinate dehydrogenase activities were stimulatedby Pb, whereas the glyceraldehyde 3-phosphate dehydrogenase activity was inhibited. Degradation of tissue protein was accompaniedwith enhanced protein carbonylation. Significant changes in trypsin, cathepsin and pronase activities were noted. Decreased aminoacid nitrogen in kidney was associated with altered transaminase activity. Additionally, fatty infiltration was observed in associationwith accumulation of elemental lead.Conclusion: It is suggested that sub-acute Pb exposure modulated certain enzymes and intermediates of major energy metabolismpathways in the renal tissue of mice to establish an adaptive mechanism against metabolic distress.

Authors: Mishra Neha , MISHRA PRAGYA , Gupta Ena , Singh Priyanka
Published: May 2023

Nannochloropsis, due to its high lipid content, small size and growth rate, can be exploited for the production of biofuel and other value-added products. This study analyzed synergistic responses of high irradiance and nitrogen deprivation on Nannochloropsis cells to enhance biomass and lipid production. The growth of Nannochloropsis was first optimized under different irradiance 50, 100, 150, 200 and 250 μmol photons m-2 s-1. The maximum specific growth rate (0.25 day-1) and dry weight (0.67 g L-1) were obtained (p<0.05) at photosynthetically active radiation (PAR) of 200 µmol photons m-2 s-1, further increase in light intensity decreased the growth rate and dry weight up to 0.2 day-1 and 0.41g L-1, respectively. The stress of high light for a short period increased the lipid content by 51.1% and decreased the protein content by 35.2% over the control values. In the second phase of the study, the combined stress of high light intensity of 200 µmol photons m-2 s-1 PAR and nitrate depletion (50%, 75%, 100% N-) were studied and observed significant (p<0.05) increase in lipid content from 21.3±1.4% to 43.2±1.56% DCW and decrease in protein from 30.7±1.3% to 16.3±1.2% DCW, respectively. The highest lipid productivity (140 mg L-1 d-1) had been observed in a culture grown at 75% N- starved cells (p<0.05). However, the further increase of nitrate deprivation to 100% decreased the lipid productivity to 107 mg L-1 d-1. Maximum accumulations of TG (19.6% DCW) were observed on 6 days (early stationary phase) in a 100% nitrogen deprived medium, although significant accumulation was observed on 4 days and 6 days of nitrate reduction.

Published: May 2023

In recent years, nanoparticles of noble metals such as silver have gained enormous attraction owing to their distinct physical, chemical, and biological properties. In the present study, silver nanoparticles (AgNPs) were synthesized from silver nitrate (AgNO3) using extracted chitosan as the reducing agent. The chitosan was extracted from the exoskeleton of the marine crab Portunus pelagicus. Three different sample solutions were prepared using 0.02mM AgNO3 in 0.5% (w/v) chitosan, 0.04 mM AgNO3 in 0.5% (w/v) chitosan, 0.06 mM AgNO3 in 0.5% (w/v) chitosan. Preliminary characterization of the formed silver nanoparticles was made based on the measurements of ultraviolet-visible (UV-Vis) spectroscopy and scanning electron microscopy (SEM). The characteristic absorbance peak corresponding to silver nanoparticles was observed at 400nm. The average size of chitosan-based silver nanoparticles was in the range of 160-530nm. The synthesized nanoparticles were further tested for their antimicrobial activity. The synthesized chitosan-based silver nanoparticles exhibited effective antibacterial activity against Gram-negative bacteria Pseudomonas aeruginosa, Escherichia coli as well as Gram-positive bacteria Bacillus subtilis, Staphylococcus aureus, and antifungal activity against Candida albicans, Aspergillus flavus, Penicillium chrysogenum. Among the different concentrations of silver nitrate solutions, a maximum zone of inhibition against all the microbial cultures was observed with chitosan-based silver nanoparticles produced using 0.06mM silver nitrate solution. The synthesized nanoparticles were further incorporated in Cotton Gauze to evaluate its antibacterial activity. It showed higher bactericidal activity against Pseudomonas aeruginosa followed by Bacillus subtilis, Staphylococcus aureus, and Escherichia coli and thus proved to have the potential to be used as wound dressing material.

Authors: Priyanka S  , Varsha R  , Riya Verma  , Ayenampudi Surendra Babu
Published: May 2023

Spirulina, blue-green algae is now worldwide used as a dietary supplement owing to its richness in protein (50-60%), antioxidants, essential fatty acids, etc. The amino acid composition of Spirulina protein ranks among the best in the plant world, more than that of soya beans.  This review article serves as an overview of why Spirulina is considered as a ‘superfood’. Its methodologies of cultivation, richness in nutrients and bioactive components, therapeutic properties in the health food circuits, and versatile utilization in various food supplements are elaborately introduced. All possible fortification of Spirulina platensis emphasizing the elevation of nutrient levels in bakery products, beverages, dairy products, extruded snacks, energy bars, infant foods, and confectionaries is briefed. Beyond, these algae convert carbon dioxide into organic substances and produce oxygen during their growth in alkaline and saline water thereby not wasting fresh water and allowing the production in barren areas. Such an organism with a plethora of health profits to humans, animals and the environment is limitless and has probably more to offer in the future.
ENCAPSULATION OF EUCALYPTUS LEAVES PHYTOPRODUCTS INTO LIPOSOMAL NANOPARTICLES AND STUDY OF THEIR ANTIBACTERIAL ACTIVITY AGAINST STAPHYLOCOCCUS AUREUS IN VIVO
Authors: Krasnopolsky Yuriy , Pylypenko Daria
Published: May 2023

Plant oils are high effective active pharmaceutical ingredients, but the extremely low bioavailability of lipophilic compounds limits their use in drugs. The encapsulation of essential oils into nanoparticles are actively studied. The aim of the research was to prepare liposomal forms of eucalyptus leaves extract and Chlorophyllipt and to study their antibacterial activity. Liposomal forms of Chlorophyllipt and eucalyptus oil extract was prepared using egg phosphatidylcholine and cholesterol by high pressure homogenization and sonication method. The average particle sizes of liposomal Chlorophyllipt and liposomal eucalyptus extract were 156.5 and 210.4 nm, respectively. Active pharmaceutical ingredient encapsulation in liposomal Chlorophyllipt and liposomal eucalyptus extract were at least 85% and at least 90%, respectively. Antibacterial activity of liposomal drugs was studied in white mice with model of staphylococcal infection, initiated by Staphylococcus aureus ATTC 209. The use of liposomal eucalyptus oil and liposomal Chlorophyllipt demonstrates no toxicity in mice. Both investigated drugs demonstrated antibacterial activity against Staphylococcus aureus in mice. A single administration of the liposomal drugs increased the survival rate up to 30-40% compared with model animals. Double administration of liposomal drugs both in liquid form and in lyophilized form increased the survival rate by at least 70 %. Moreover, in the group of animals treated liposomal eucalyptus oil, the number of surviving animals was 100%, while in a group of liposomal Chlorophyllipt it was 80%.

Authors: Alshehrei Fatimah
Published: May 2023

Food additive azo dyes are toxic substances added to food to enhance taste or appearance. Synthetic dyes are widely used in the color of some products such as jelly, sweets, or medicines.
Tartrazine (E102) is one of the synthetic dyes used in food coloring. World health organization (WHO) recommended the acceptable daily intake of this dye is (7.5 mg/kg) body weight. In the human body, the microorganism can degrade these substances to intermediate compounds that can be more toxic in case of increasing these substances in the human body. Pseudomonas aeruginosa is one of the human intestinal microflorae which is able to degrade tartrazine. Decolorization assays by spectroscopy and chromatography analysis confirmed that P. aeruginosa can degrade tartrazine to toxic products such as Sodium 2- amino benzenesulfonate (195.15) m/z. This study discussed the effect of tartrazine and its degradation products on liver and kidney tissues. Twenty-eight female albino rats were examined by injecting them with this dye for two months. We divided the Rats into four groups each one received different treatment. Results showed a significant decrease in the body weight of rats in the control group in G2, G3, and G4. Physiological analysis of kidney and liver parameters including AST, ALT, and ALP, were markedly elevated in rats of all treated groups. Histological examination of liver tissues indicated hepatic changes in all tested groups as compared with the control group. Treatment with tartrazine and its products led to mild hepatocytes lesions. Histopathological analysis of the kidney tissues revealed an average renal capsule and other interstitial tissues in the control group, other groups received different doses of tartrazine, revealed that blood vessels appeared mildly congested with interstitial inflammatory infiltrate.
PERSPECTIVE ON THE PROS AND CONS, MANUFACTURING ASPECTS, AND RECENT ADVANCES IN NON-DAIRY MILK ALTERNATIVES
Authors: DHANKHAR JYOTIKA
Published: May 2023

Cow's milk has served as a crucial part of the human diet for ages due to its nutritional benefits. However, in recent years, non-dairy milk alternatives (NDMAs) have surpassed cow's milk in its popularity due to different issues associated with cow's milk consumption. Although NDMAs contain additives, sweeteners, are deficient in good quality protein and entail a lack bioavailability of nutrients, they make for an appealing choice of consumers since they are a good source of bioactive components and carry a healthy fatty acid profile. Despite their popularity, there are concerns regarding their commercialization, as they lack stability upon storage and standardized technology for their large-scale production. The problems present a broad field for both the food industry and researchers to work synergistically in developing novel milk alternatives that are wholesome, healthy, cost-effective, and have better techno-functionality. This review comprehensively assesses the current scenario, health aspects, and production technologies in developing NDMAs, considering the accompanying challenges and promising prospects.

Published: May 2023

The purpose of this study was to evaluate the antifungal effects of thymol on fungi planktonic and biofilm cells. Firstly, the antifungal activity of a thymol-based product on reducing fungi load in poultry drinking water samples was assessed in vitro using the plate count method. Samples were treated by increasing concentrations of thymol (1, 2 and 4 g.l-1 of product). Reduction is about one log unit for 1 g.l-1, about two log units for 2 g.l1, and a total desperation for 4 g.l-1. Secondly, the antifungal activity was tested on biofilms formed on coiled pipes using an experimental arrangement simulating animals watering conditions in poultry farming. Two concentrations (1 and 2 g.l-1) were used in two ways, preventive and curative treatment. The first one consisted in preventing fungal development on pipes and the biofilm formation. The second consisted in treating biofilms that have already settled on pipes. The plat count method was used to check the antifungal activity of thymol. Data of this experiment data have shown that thymol may prevent Candida albicans and Aspergillus niger proliferation in the experimental arrangement. After just a week, a significant reduction (P<0,05) was shown with the concentration 1 g.l-1. The reduction was much important when the product was used at a concentration of 2 g.l-1 (about tree log units). For curative treatment, results showed a significant reduction (P<0,05) of C. albicans load after only 24 hours with 1 g.l-1 (about one log unit). With this same concentration, reduction is more important over time for both spices (about four log units after a week). A significant reduction (more than two log units) was showed in just 24 hours of treatment with the concentration of 2 g.l-1. This work offers an alternative solution to chemical biocides, which can treat water and disinfect distribution system in poultry farming.

Published: May 2023

Large gray and Large white geese breeds were created in Ukraine and are widespread. At the same time, the nutritional value of their meat is insufficiently studied. Therefore, this work aimed to study and compare the chemical composition and amino acid profile of the muscles of the chest and thighs of geese of these breeds in semi-intensive growing. The study used 20 heads of geese of both sexes of the Large gray and Large white breeds, which were raised under similar housing and feeding conditions. Muscle samples were analyzed following current regulations in Ukraine, harmonized with relevant international standards. Studies have shown no significant differences in the muscle content of males and females of these breeds in terms of moisture, protein and ash, but a more significant difference in fat content was observed. In the thighs of females of Large gray geese fat content was higher than in the thighs of males of this breed by 0.29% (P<0.05). At the same time, in females of the Large white breed, on the contrary, higher fat content than in males (by 0.27%) was observed in the chest muscles (P<0.05). The chest muscles of both males and females of both breeds had more moisture and more crude protein than the thigh muscles. In contrast, the thigh muscles had a higher fat content (P<0.05). As for protein, the muscles of the chest and thighs contained all the essential amino acids. However, the amino acid profile of male and female proteins of the same type in different muscle types, both within one breed and between breeds, differed slightly in the content of some amino acids, with the statistically reliable (P<0.05) difference in some of them. Comparison of the amino acid profile of chest and thigh muscle proteins of both breeds of geese with the reference protein (FAO/WHO, 2013), showed that the muscle protein of geese of Large gray and Large white breeds contains a sufficient amount of all essential amino acids. The essential amino acid indices of the chest and thigh muscle proteins were similar for both breeds and were approximately 1.8-fold higher than the reference protein index. These data indicate the high nutritional value of meat of both goose breeds and the feasibility of their further use for meat production in Ukraine.

Wind energy can be used as an inexhaustible option for human consumption. Wind turbines offer a promising solution for off-grid areas. Darrieus turbine is one of the types of turbines that can be more efficient than other types if it is used by knowing its characteristics. The complex dynamic mechanism of the flow around the machine has led to its aerodynamic optimization problems remaining complex. This article reviews the applied methods in modeling vertical axis turbines and implicitly shows the turbine operation by presenting the results of these methods. Knowing these methods is important because each has its advantages and disadvantages and should be selected depending on the purpose of the research. One of the problems with Darrieus turbines is their poor start-up, which has been little researched so far. Finally, a suitable method that can model the start-up is introduced.

Published: May 2023

Plant production requires improvement in nursery-field techniques to increase yield and economic gains. Manipulating the interaction between biotic and abiotic factors in the production of forest seedlings can improve productivity. In this context, we examined and selected the climatic variables that influence the yield of forest seedlings treated with different dosages of growth biopromoter Trichoderma sp. Climatic data were obtained from the NASA Power platform and correlated with growth data from forest seedlings treated with Trichoderma sp. The growth variables used were base diameter, height, and north-south and east-west canopy diameters. Climatic variables were selected by multiple regression models via forward-backward stepwise regression, and artificial intelligence via random forest (RF) method. The climatic variables that most influenced the growth of plants treated with Trichoderma sp. were the incidence of shortwave insolation on the horizontal surface, longwave thermal infrared radiative flux, relative air humidity, temperature, wind speed, and precipitation. Wind speed influenced only seedling height, while temperature, precipitation, and radiative flux interfered with all growth variables. Both the multiple regression and RF methods similarly describe the interaction of fungus × plant × environment. Most of the climatic variables detected via multiple regression coincided with the RF procedure. Future studies on the application of Trichoderma sp. as a biopromoter of growth should consider the identified climatic variables to optimize the production of forest seedlings in nurseries and in the field.

Published: May 2023

The structure evolution of amorphous metallic alloys during different kinds of thermal effects is an important problem of disordered systems physics. A precise evolutional model would allow predicting the formation of such a structural state, providing the necessary physical and mechanical alloy properties.The paper is devoted to the problem of modelling the explosive crystallisation process in metal glasses induced by laser, supplemented by experimental results.A theoretical model of laser-induced explosive crystallisation in metal glasses is proposed. A pulse laser heating method for the surface processing was developed, making it possible to obtain two-layer structures with an adjustable thickness of the amorphous crystalline layer.The proposed model is assumed to test and optimes for metal glasses of other chemical compositions.A theoretical model of laser-induced explosive crystallisation in metal glasses allows for predicting and controlling structure changes to obtain the desired properties.The investigation of structure changes at rapid heating of amorphous alloys by experimental methods is very limited in obtaining data and their interpretation. For that reason, combining the modelling with experimental measurements is proposed. The results of this work have value for a scientist in material science, physics and engineering, which use nonequilibrium physical processes to obtain new materials, including nanoscale systems.

Point-of care ultrasound (PoCUS) is a diagnostic paradigm, instrumental in the evolving anaesthesiologist’s role towards a perioperative physician. The purpose of this article is to propose expert suggestions for a national standard towards official certification in perioperative PoCUS. Previously published recommendations in this journal constituted a first move towards a structured PoCUS pathway for Belgian anaesthesia residents1. This article defines in detail a pathway towards obtaining competency in airway ultrasound, lung ultrasound, gastric ultrasound, hemodynamic volume assessment, basic transthoracic and transesophageal echocardiography. An updated overview of the international literature on the education of perioperative PoCUS serves as a scientific backbone.

En la actualidad la conservación de los recursos hídricos es fundamental para preservar el medio ambiente y la vida de los diferentes ecosistemas y de los seres humanos. Las empresas a nivel global depositan sus efluentes en los cursos de los cuerpos hídricos, por tal motivo, se realiza este estudio técnico para mejorar el proceso de tratamiento de aguas oleosas que son descargadas al Río Teaone por la Central Termoesmeraldas II. Mediante el análisis experimental se determinan los análisis físico-químicos y microbiológicos del agua aceitosa, utilizando instrumentos como: pH-metro, conductímentro, colorímetro y varios reactivos. Posteriormente se procede analizar y tabular los resultados. Con el análisis del caudal, la turbidez, pH, y sólidos totales disueltos se determinó que no cumple con la legislación ambiental ecuatoriana para descargar a un curso de agua dulce. Por tanto, se analizó el filtrado y el tiempo de sedimentación, observando que por gravedad no se lograría separar el agua del aceite, pero adicionando policloruro de aluminio se logra la separación por sedimentación de los flóculos. De tal manera que con la prueba de tratabilidad se determinó que adicionando 70 mg/L se forman flóculos y se puede separar el agua del aceite, por tanto, se sugiere a la empresa aplicar este procedimiento que mejorará la condición de las aguas oleosas descargadas al Río Teaone.

This study examines the relationship between macroeconomic factors and foreign direct investment (FDI) inflows in developing countries. The data from the World Bank covers 21 years, from 2000 to 2020 was analyzed using the panel regression approach with E-Views. Panel regression analysis, including model selections and diagnostics, is used for inferential analysis. The main contribution of this study is the influence of political factors on FDI inflows. Political stability and corruption control are technically the most important conditions for FDI inflows in developing countries and were introduced in this study. This study found a positive relationship between GDP growth rate, imports, inflation, and corruption index with FDI inflow, confirmed by previous studies. The study also implies that the exchange rate, exports, and political stability have a negative relationship with the level of FDI in developing countries. In addition, the study found that GDP growth rate, imports, and exports significantly impact FDI inflows in developing countries, while the other variables are not significant. In other words, this result shows that macroeconomic and political factors such as import, export, exchange rate, corruption control, and political stability impact FDI inflows. Moreover, this paper provides policy recommendations to support developing countries' economies by attracting FDI and increasing its inflow.

Authors: Mohajan Devajit , Mohajan Haradhan Kumar
Published: May 2023

The minimal amount of body fat is necessary for normal physiological functions that manages body temperature, creates energy to perform all the physical activities, and protects the organs of human body. Storage body fat consists of fat accumulation in adipose tissue. Total body fat in human body is the sum of essential fat and storage fat. At present body fat percentage is considered as one of the most accurate obesity evaluation tools. To determine body fat accurately the clinicians should use the most appropriate, accurate, and accessible strategies available in the scientific research area. Accurate measurement of body fat and lean body is essential for the nutrition assessment, and an individual’s overall health and well-being. In this study some measurement processes are discussed to determine body fat percentage (BFP) properly of a person by the analysis of two compartment model: fat mass and fat free mass.

The present study purposed to investigate the degree of stress on companion dogs after grooming service. For this purpose, we analyzed the effect of skin service on changes in the concentration of serum cortisol, the body weight, body temperature, heart rate and skin lesions, and obtained results as follows. Compared to the control group or the ordinary grooming group, the stress grooming group showed high concentration of serum cortisol, and their recovery was slow but they were recovered to the normal state in 24 hours. Body temperature increased in the ordinary grooming group and the stress grooming group compared to the control group. Body temperature after 4 hours from grooming service was lower than that just after the service, and the temperature before the grooming service was restored in 24 hours from the grooming service. The results of this experiment showed that grooming service to pet dogs causes stress and increases the rise of body temperature, heart rate and the concentration of serum cortisol. However, these symptoms disappeared within 24 hours from the experiment, and skin inflammation was observed in a dog but not serious.

While the population raising companion animals is rapidly increasing and related industries are growing, social problems caused by companion animals, including dog bite accidents, are also increasing. Dog biting is an important issue for personal safety and public health, and is a major issue that causes social conflicts and costs. However, there is still a lack of accurate statistical data or research related to dog biting in Korea, and the legal system is also insufficient. In this study, after examining the current status of dog biting in Korea, related statistics, research data, and related laws in foreign countries, laws and cases that effectively reduced dog biting accidents were introduced. Then, based on this, alternatives applied to reality in Korea were presented.

Sixteen types of plant foods were selected, which could add taste, aroma, and functional efficacy during cooking and manufacturing processed products. Hot-water extracts were prepared to examine the antioxidant activities. 1,1-diphenyl -2-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzothiazoline-6- sulfonic acid (ABTS) radical scavenging ability were measured and compared. In addition, the content of anti-oxidative compounds was also evaluated by measuring the total phenol content and flavonoid content of the extracts. As for the DPPH radical scavenging activity, perilla leaf, sesame leaf, potato, and pepper showed a scavenging rate of over 60%, and seaweed, soybean, and radish showed low activity. In ABTS scavenging activity, perilla leaf and broccoli showed high antioxidant activity, and seaweed showed the lowest value. Antioxidant properties appear better as the contents of some polyphenolic compounds and flavonoid-based components are higher. Perilla leaf had the highest total phenolic content and flavonoid content, and sesame leaf, radish seed, and mallow also showed high content of anti-oxidative compounds.
