The Help of God and Fear of Man: Comparing Anxiety and Religiosity in Fury (2014) and Merah-Putih (2009)

This research aims at investigating the influence of religiosity on anxiety during the war. This research compares two contrasting military leader characters to identify the influence on the way that these characters cope with war-induced anxiety. The main comparative objects are the characters Don from the movie Fury (2014) and Amir in Merah-Putih (2009). Both characters show similar anxiety and religiosity but differ in how they cope with anxiety. The general assumption is that religiosity helps to cope with anxiety. This research uses Freud’s psychoanalysis theory to study the characters. By comparing these characters, we may find the relation of religiosity towards anxiety, and we may also find other influences such as the character’s motivation and backstory. The five dimensions of religiosity, as explained by Glock Stark and Freud’s psychoanalytic theory on anxiety, determine religiosity and anxiety. The variables are expressed through practice, discourse, and symbols by both characters in scenes and dialogues. The findings are listed in three items: 1) The coping mechanism for anxiety works not only to repress but also to create new anxiety. 2) The new anxiety can be so much worse than the initial anxiety. 3) Religiosity is not a necessary variable in dealing with anxiety. Additionally, the founding of new anxiety contributes to previous theory on anxiety.

Harnessing the metabolic modulatory and antioxidant power of 1-(3-Phenyl-Propyl) cyclopropane and melatonin in maintaining mango fruit quality and prolongation storage life

BackgroundThe aim of this study was to compare and investigate the effects of 1-(3-phenyl-propyl) cyclopropene (PPCP) and melatonin (MT) as anti-ethylene agents on postharvest senescence, quality, chilling tolerance, and antioxidant metabolism in the mango fruit cv. “Keitt”. The study involved exposing the fruit to 20 μL L− 1 PPCP or 200 μM MT, in addition to a control group of untreated fruit, before storing them at 5 ± 1 °C for 28 d. The findings revealed that the treatments with PPCP and MT were effective in reducing chilling injury and preserving fruit quality when compared to the control group.ResultsThe use of 20 μL L− 1 PPCP was an effective treatment in terms of mitigating chilling injury and preserving fruit quality for 28 d. This was attributed to the decrease in metabolic activity, specifically the respiration rate and the production of ethylene, which led to the maintenance of fruit firmness and bioactive compounds, energy metabolism, and antioxidant activity, such as ascorbic acid, total flavonoids, trolox equivalent antioxidant capacity, dehydroascorbate reductase, glutathione reductase activity, ATP, and ATPase activity. The study also found that the MT treatment at 200 μM was effective in reducing chilling injury and weight loss and improving membrane stability. Additionally, it led to a decrease in malondialdehyde content and electrolyte leakage, and the maintenance of fruit quality in terms of firmness, peel and pulp colour values for mango peel and pulp total carotenoid content, as well as phenylalanine ammonia lyase and tyrosine ammonia lyase activity. These findings indicate that PPCP and MT have the potential to be efficient treatments in maintaining mango quality and minimizing post-harvest losses.ConclusionThe utilisation of treatments with 20 μL L− 1 of PPCP or 200 μM MT was found to effectively preserve the postharvest quality parameters, in terms of bioactive compounds, energy metabolism, and antioxidant activity, of mangoes cv. “Keitt” that were stored at 5 ± 1 °C for 28 d.

On the Path to Sustainable Cosmetics: Development of a Value-Added Formulation of Solid Shampoo Incorporating Mango Peel Extract

The excessive use of water and plastic packaging in the cosmetic industry imposes the need to develop sustainable alternatives. Moreover, agricultural by-products are reported in the literature to be rich in bioactive properties, namely high antioxidant capacity, suggesting their potential use in cosmetic formulations as substitutes for commercial additives. The aim of this work was the development of a sustainable formulation of solid shampoo, incorporating extracts from mango peel as antioxidants. The characterization of the extracts revealed the presence of several phenolic compounds and a strong antioxidant capacity. Six formulations of solid shampoo were produced by varying the quantity of the additives: tocopherol and butylated hydroxytoluene, used as positive controls, and mango peel (MP) extract. The antioxidant capacity assays demonstrated that the MP extract increased the antioxidant activity of the shampoos, in comparison to the positive controls and the stability tests revealed that the MP extract is a stable ingredient. Hence, it was concluded that the MP extract is a strong source of antioxidants with the potential to replace commercial antioxidants in cosmetics. Thus, it was possible to develop a value-added formulation of solid shampoo, eliminating the use of water and plastic for the packaging, and reusing waste from the food sector.

Spreadability, Total Dissolved Solids and Likeability of Mango Jam with a Combination of Mango Flesh and Peel Arum Manis (Mangifera Indicates L)

After being harvested, mango fruit will quickly spoil due to the high water content in the fruit, so efforts need to be made to process it to extend its shelf life, one of which is processing it into jam. To get good jam you need the right composition of sugar, acid and pectin. The part of the mango fruit that is widely consumed and processed is the flesh, while the skin and seeds are not widely used even though the skin of the mango fruit contains quite high pectin. This research aims to determine the effect of the combination of mango flesh and mango skin on spreadability, total soluble solids, and panelists' preferences for jam. The method used is Completely Randomized Design (CRD) 1 factor, namely a combination of mango skin and mango flesh with 5 treatment levels: P1 (20%: 80%), P2 (30%: 70%), P3 (40%: 60%), P4(50%: 50%) and P5 (60%: 40%). Parameters observed: spreadability, total dissolved solids, and preference test. Data were analyzed using Variance Analysis and the smallest significant difference (if there is a difference) with a confidence level of 5%. The liking test will be carried out on 30 panelists (untrained) using a 5-level liking scale: very dislike (1), dislike (2), neutral (3), like (4) and very like (5). The results of the study showed that the higher the use of mango peel pulp and the less mango fruit pulp, the lower the spreading power, where the highest spreading power was in treatment P1 and was not different in treatment P2. However, the total dissolved solids value is getting higher. Panelists liked the color, taste and spreadability of treatments P1, P2 and P3 (not significantly different), while the aroma was preferred up to treatment P4.

A multicriteria approach for biomass availability assessment and selection for energy production in Burkina Faso: A hybrid AHP-TOPSIS approach

Burkina Faso's agricultural and industrial sectors are sources of biomass production which are not well tapped. However, the exact quantities available and mobilizable with connection to recovery technologies are not available in the literature. Also, there is very little data on the criteria for the optimal selection of the biomasses to be valorized. In this article, quantification of the main biomasses produced in Burkina Faso has been carried out. Additionally, sustainable biomass selection criteria have been established. A hybrid (AHP-TOPSIS) multi-criteria decision-making (MCDM) approach was used to prioritize suitable biomass resources based on defined criteria for bioenergy production. Based on expert opinions and an in-depth review of the literature, six main biomass selection criteria were established: i) biomass availability and accessibility, ii) competitive uses, iii) pollution potential related to residue accumulation, iv) economic impact, v) biomass energy content, and vi) availability of appropriate biomass conversion technologies. Moreover, five potential biomasses were investigated, including cotton stalks, rice husks, cashew nutshells, mango peels, and mango pits. The results of the evaluation showed that cotton stalks were the best option.

Yogurt Enriched with Mango Peel Extracts (Mangifera indica) in Chitosan–Xanthan Gum Dispersions: Physicochemical, Rheological, Stability, and Antioxidant Activity

Different strategies have been developed to incorporate bioactive compounds into food products to improve their biological activity against degradation effects. The aim of this study was to develop natural yogurt enriched with mango (Mangifera indica) peel extracts (MPEs) in chitosan–xanthan gum dispersions and to evaluate their physicochemical, rheological, and antioxidant activity. A hydroethanolic extract of mango peel was obtained, with a yield of 33.24 ± 1.27%, a total content of phenolic compounds of 305.04 ± 10.70 mg GAE/g, and an antioxidant activity of 1470.41 ± 59.75 μMol Trolox/g. The encapsulation of the extracts was achieved using a chitosan–xanthan gum dispersion, resulting in the rheological characteristic of a strong gel. The incorporation of dispersions into yogurt did not modify the physicochemical properties and increased their bioactive properties. The rheological properties show samples with double yield points and a decrease in viscoelastic parameters. These results show dispersions as a strategy to incorporate bioactive compounds into dairy products, preserve the physicochemical and rheological properties of yogurt, and improve their biological activities (such as antioxidant activity) and activities related to the compounds found in the MPE.

Investigating the Water Relations in Aqueous Extract Powders of Mango (Mangifera indica) Peel and Seed Waste for Their Use in Food Matrices as a Value-Added By-Product.

This study investigated the potential uses of discarded mango peel and seed parts by analyzing their water sorption behavior, hydration kinetics, and stability when converted into extract powders at pH 3 and 10. The results revealed that peel extracts had a higher water adsorption capacity compared with seed extracts due to differences in their composition. Peel extracts were primarily composed of carbohydrates (approximately 75%) with a low protein content, while seed extracts contained fewer carbohydrates (less than 30%) but higher levels of proteins (more than 30%) and lipids. The critical water content for maintaining the glassy state of peel extract powders during storage was found to be 0.025 and 0.032 g of water/g for extracts obtained at pH 3 and 10, respectively. In contrast, the Tg values of seed extracts remained relatively unchanged across different water content levels, suggesting that proteins and lipids inhibited the water's plasticizing effect in the solid matrix. These findings indicate that both mango waste fractions exhibit distinct hygroscopic behaviors, necessitating different approaches to processing and utilization. These extracts hold potential applications for various food products such as beverages, gels, sauces, or emulsions, contributing to the reduction in waste and the creation of value-added products from mango residues.

Upcycling mango peels into a functional ingredient by combining fermentation and enzymatic-assisted extraction

This study aims at upcycling mango peels by a sequential application of enzymatic hydrolysis, using Viscozyme and Pectinex at 50 °C for 2 h; and fermentation, using L. plantarum and B. animalis at 48 h for 37 °C. The use of Viscozyme led to a considerable increase in the concentration of galacturonic and glucuronic acids in the unfermented samples (308.96 and 12.97 mg/100 ml higher than control, respectively), whereas the use of Pectinex resulted in higher oligosaccharide solubilization (5.3 % more than control). None of the enzymes influenced microbiological growth. The recovery of gallic acid aglycone increased 17-fold over the control when Pectinex and B. animalis were used. Similarly, the recovery of mangiferin aglycone increased by 60 % after fermentation by either bacteria. The results indicate that this sequential processing strategy might be utilized to extract phenolic aglycones and produce functional ingredients from mango peels.

“Be Spiritual and Employ Technology in your Ministry”: An Experience of Sermons Amid COVID-19 by Bishop Harrison Sakala of Tabernacle of David Assembly of God in Zambia

Pentecostal preachers in Zambia, like Bishop Harrison Sakala of the Tabernacle of David Assembly of God, reoriented their sermons during online worship services in response to the COVID-19 pandemic in its early stages. The article shows that the outbreak of COVID-19 reshaped the sermons and the role of the “men of God” therein. They blended their sermons with an emphasis on embracing science as opposed to being overly spiritual, adhering to prevention and control measures stipulated by the health authorities and the state, and instilling hope in the masses. The article concludes that the sermons not only pointed to the media as sites for communicating shifts within Pentecostal circles on tackling the pandemic but also signified the collaborative role played by Pentecostal preachers in mitigating the pandemic through the media.

Comparing and integrating TMT-SPS-MS3 and label-free quantitative approaches for proteomics scrutiny in recalcitrant Mango (Mangifera indica L.) peel tissue during postharvest period.

Despite substantial advances in the use of proteomic technologies, their widespread application in fruit tissues of non-model and recalcitrant species remains limited. This hampers the understanding of critical molecular events during the postharvest period of fleshy tropical fruits. Therefore, we evaluated label-free quantitation (LFQ) and TMT-SPS-MS3 (TMT) approaches to analyse changes in the protein profile of mango peels during postharvest period. We compared two extraction methods (phenol and chloroform/methanol) and two peptide fractionation schemes (SCX and HPRP). We accurately identified 3065 proteins, of which, 1492 were differentially accumulated over at 6 days after harvesting (DAH). Both LFQ and TMT approaches share 210 differential proteins including cell wall proteins associated with fruit softening, as well as aroma and flavour-related proteins, which were increased during postharvest period. The phenolic protein extraction and the high-pH reverse-phase peptide fractionation was the most effective pipeline for relative quantification. Nevertheless, the information provided by the other tested strategies was significantly complementary. Besides, LFQ spectra allowed us to track down intact N-glycopeptides corroborating N-glycosylations on the surface of a desiccation-related protein. This work represents the largest proteomic comparison of mango peels during postharvest period made so far, shedding light on the molecular foundation of edible fruit during ripening.

Optimization of gallic acid-enriched ultrasonic-assisted extraction from mango peels

Abstract Gallic acid is recognized as a notable bioactive compound among secondary polyphenolic metabolites. In the current study, gallic acid-enriched extracts were obtained from mango peels using different solvents (ethanol or water) via ultrasound-assisted extraction, and optimized yields were compared with the conventional extraction technique (decoction). Independent variables for the optimization through response surface methodology were ethanol concentration (0–60%), solvent ratio (10–50 mL/g), temperature (30–60℃), and time (10–30 min) for ethanolic extraction. However, extraction carried out by using water had extraction conditions of pH (2–8), solvent ratio (20–0 mL/g), extraction temperature (40–70℃), and time (30–60 min). The optimized yield of gallic acid obtained through ethanol was 5.75 ± 0.21 mg/g, whereas 3.14 ± 0.24 mg/g of gallic acid was quantified in extraction through water. The results were compared with the aforementioned conventional method of decoction, and it was concluded that the ethanolic extracts of mango peels showed the highest gallic acid yield and total flavonoid contents. The obtained extracts could be a potential source of polyphenolics, especially gallic acid, for use in nutraceuticals as well as in other food applications.

A SYSTEMATIC REVIEW OF THE APPLICATION OF NATURAL POLYMERS IN THE FORMULATION OF ORO-DISPERSIBLE TABLET

Oral drug delivery is still the preferred method for administering many medications. Recent technological advancements have led to the development of orally disintegrating drugs, which offer improved patient compliance and convenience. Orodispersible(ODTs) drugs are a unique dosage form that dissolves in the mouth within 1-3 min without the need for chewing or water. Over the past three decades, orodispersible drugs have gained popularity as an alternative to traditional drugs due to their increased patient compliance, solubility, and stability. This new technology meets both the pharmaceutical and patient demands and provides a comfortable dosage method for pediatric, geriatric, and psychiatric patients with dysphagia. Natural substances are preferred over synthetic ones because they are more accessible, less expensive, non-toxic, and chemically inert. Natural polymers, such as locust bean gum, banana powder, mango peel pectin, and Mangifera indica gum, enhance drug characteristics and are used as binders, diluents, and super disintegrants to speed up disintegration, increase solubility, and provide supplements. Manufacturers are increasingly using natural polymers due to various issues with medication release and adverse effects. This review article views the development of ODTs, challenges in formulation, new ODT technologies, and our suspects.

Word of God and Word of Man as an Argument for Diachronic Differentiation in the Book of Jeremiah

According to some scholars some of the oldest texts in the book of Jeremiah can be found in the words from the foe from the north in Jer 4–6. Originally these texts were words of the prophet and spoken from a human point of view. Their characterization as Words of YHWH and the divine perspective is therefore regarded as a result of the literary development of these texts and the theological reflection on the disaster of 587 BC. The paper will follow this approach. The possibilities and limits of the distinction between Word of God and word of man as an indication for literary development in the texts from the foe from the north shall be examined.

Sewage sludge co-digestion with mango peel liquor: impact of hydraulic retention time on methane yield and bioenergy recovery

Sewage sludge co-digestion with mango peel liquor: impact of hydraulic retention time on methane yield and bioenergy recovery

Conceptualism Philosophy of the “Biblical Time” in the Works of Jacob Druskin

In the article the author analyzes the time ontology as noumenal relation, developed in the treatises of Ja.S. Druskin and genetically associated with the “leap” to biblical thinking implemented by L.I. Shestov. It is shown that the path of “conversion” of consciousness described by Ja.S. Druskin has the character of “inner mystery” of the soul, ascending to the counter gifts of the Spirit. This is a kind of “inner ritual” that the soul performs in every momentary effort to stand before the Creator and Judge, seeking reciprocal grace. Methodologically Ja.S. Druskin radicalizes the way of overcoming the “natural attitude” of consciousness, started by E. Husserl, and characterizes it as “philosophical paganism”, which can be overcome only by the biblical attitude of consciousness. The latter is a relation that transcends any ontology of the created world and carries out the act of returning the created “I” to its uncreated image, which is assumed as a relation to the absolute “Thou” of the Creator. This is the “personal eternity” that opens not as a logical timelessness, but as a special vision – as being in the Face of God. Exploring the architectonics of the noumenal “I – You” relationship, Ja.S. Druskin develops the philosophy of dialogue as new Philosophia prima, which includes the whole gamut of the traditional metaphysical problematics in the context of the primary absolute “I – Thou” relationship, including rethinking the category of time. In this context, the category of time acquires new eschatological meaning, since it is fi lled not with just simple duration, but with the process of human transformation – the transition from the “shadow of death” into eternity, from the state of immanent lies to the recovery of the gift of grace and the rediscovery of the image of God in man.

The potential of in-house pectinolytic enzymes for industrial application

Pectinases are one of the essential groups of enzymes in the field of biotechnology and have applications in various industries including food, textile, paper industries, and waste management. Pectinases, like other industrial enzymes, are usually expensive. This research aimed at producing in-house pectinase from waste fruits, by an inductive mechanism. The study specifically optimized the production of in-house pectinases from mango and pawpaw peels used as substrates and also demonstrated the hydrolytic potential of the substrate-based in-house pectinase enzymes through viscosity analysis. The mango and pawpaw peels obtained from Blue Skies Co. Ltd. were oven-dried and milled to sieve particle sizes depending on the mode of the fermentation process. Measured amounts of the substrates were put into 50 ml Falcon tubes and subjected to both solid-state and submerged fermentation processes. The substrates were inoculated with one milliliter of Aspergillus niger isolate suspension and incubated at 30 °C for 2, 4, 6, 8, and 10 days under both fermentation processes. The crude enzyme extracts (in-house pectinolytic enzymes) obtained from the mango and pawpaw peels of both fermentation processes were used as enzyme sources for the hydrolysis of 1% w/v pectin solution prepared in phosphate buffer, pH 6.8 at 40 °C in viscosity analysis. The viscosities of the various treatments were recorded at different time intervals of 10, 20, and 30 min. Based on the viscosity analysis, it was observed that pectinolytic enzymes from pawpaw peels showed higher pectinolytic potential relative to the mango counterpart for both fermentation processes. However, there were consistent optima at day 4 for the mango peels and day 6 for the pawpaw peels using the submerged fermentation process. Also, there was a linear correlation between the pectinolytic activity and incubation period. The results obtained from this study show a higher potential to produce pectinases from agro-wastes such as mango and pawpaw peels for industrial purposes using an appropriate fermentation process.

An Overview of Natural Disintegrating Agent Used in Dispersible Tablets

The oral therapy is the most commonly used method for administering many medications since it is thought to be the safest, most practical, and least expensive method. Fast dissolving pills are highly popular right now because they dissolve or easily dissolve in the mouth after administration without the need for water. Fast dissolving tablets have been developed to address the drawbacks of conventional dose forms, particularly dysphagia (refers to problem in which it becomes difficult to swallow), in pediatric and geriatric patients. Natural materials offer an advantage in comparison to the synthetic ones since they are more easily accessible, cost effective, not harmful, and chemically inert. By acting as a binder, diluent, and superdisintegrant, natural polymers such as locust bean gum, banana powder, mango peel pectin, Mangifera indica gum, and Hibiscus rosa-sinensis mucilage improve tablet properties, increase the solubility of drugs which are insoluble or poorly soluble, helps in reducing the disintegration time, and aid as nutritional supplements. Natural polymer is derived from natural source, are economical, not harmful, decomposable, and environmentally helpful, free of negative effects, restorable, and serve as nutritional supplements. Studies have shown that natural polymers are more effective and safer than manufactured polymers. The aim of the current article is to study and examine natural polymers which have been approved by Food and Drug Administration for use in quick dissolving tablets.

Formulation and Evaluation of Orodispersible Tablets of Rizatriptan Benzoate

The major intention of this work is to formulate and evaluate the orodispersible tablets of Rizatriptan benzoate by direct compression technique for the management of migraine. In this work natural superdisintegrants are utilized for rapid disintegration of the formulated dosage form. In addition the natural superdisintegrants were compared for superior effect which was shown by the dehydrated banana powder. The formulation containining banana powder showed the lesser disintegrationt time and higher drug release when compared with the formulations containing mango peel pectin and Gellan gum.

Chitosan/polyvinyl alcohol-based nanocomposite films incorporated with L-Glu surface functionalized ZnO NPs: Physicochemical, photocatalytic, antimicrobial and antioxidant properties evaluation

Present work describes fabrication of active nanocomposite films (NCs) by incorporation of functionalized ZnO NPs (2, 4, 6 and 8 wt%) onto blended polymers chitosan/polyvinyl alcohol (CS/PVA). The required ZnO NPs prepared for this work by novel biogenic method using water extract of mango peel ash (WEMPA), and surface functionalized by L-Glutamic acid (L-Glu) and composite films were prepared by solvent casting method. The barrier properties, tensile strength, and antioxidant activity of the prepared films showed improved by addition of different percentage content of the ZnO-L-Glu NPs. The photocatalytic activity of the prepared films were confirmed by degradation of the methylene blue dye up to 98% in 120 min duration under sun light expose noticed. Further, prepared NC films were tested for inhibition to S. aureus (gram-positive) and E. coli (gram-negative) bacteria, and emerged as a good antibacterial. Therefore, the new CS/PVA/ZnO NPs-Glu films prepared in this work (CPZG), could be used for the food packaging as well as photo decolorization for the environmental remediation applications.

Interaction mechanism of carotenoids and polyphenols in mango peels

In this study, carotenoids and polyphenols were demonstrated to be the major active substances in the crude pigment extracts (CPE) of mango peels, accounting for 0.26 mg/g and 0.15 mg/g, respectively. The interactions between carotenoids and polyphenols in CPE was observed, as evidenced by that polyphenols significantly improved the antioxidant activity and storage stability of carotenoids in the CPE. Meanwhile, scanning electron microscopy showed that polyphenols are tightly bound to carotenoids. To further elucidate the interaction mechanism, the monomers of carotenoids and polyphenols were identified by HPLC and LC-MS analysis. Lutein (203.85 μg/g), β-carotene (41.40 μg/g), zeaxanthin (4.20 μg/g) and α-carotene (1.50 μg/g) were authenticated as the primary monomers of carotenoids. Polyphenols were mainly consisted of gallic acid (95.10 μg/g), quercetin-3-β-glucoside (29.10 μg/g), catechin (11.85 μg/g) and quercetin (11.55 μg/g). The interaction indexes between carotenoid and polyphenol monomer of CPE were calculated. The result indicated that lutein and gallic acid showed the greatest synergistic effect on the scavenging of DPPH and ABTS radical, suggesting the interaction between carotenoids and polyphenols in CPE was mainly caused by lutein and gallic acid. Molecular dynamics simulations and thermodynamic parameters analysis demonstrated that hydrogen bonding, electrostatic interactions, and van der Waals forces played dominant roles in the interaction between lutein and gallic acid, which was confirmed by Raman and X-ray diffraction. These results provided a new perspective on the interaction mechanism between carotenoids and polyphenols, which offered a novel strategy for the enhancement of the activities and stability of bioactive substances.
