Value-based teaching English language and literature
Aim. The ultimate aim became the realisation of the political ideas of democracy, equality, and social justice (Orlenius, 2001; Svingby, 1994, p. 57). The current study aimed to explore the concept of value education at Poornaprajna institutions that have adopted value education in their curriculum. Methods. The study was designed in a qualitative exploratory research approach. The researcher had adopted the interviews for a case study as a microscopic social study through observation and also studied the archival records in Poornaprajna institutions. The informal group interviews were administered as part of a qualitative research approach, which aimed to collect data from twenty eight English teachers and students of Poornaprajna institutions. Result. The validity and trustworthiness of the study were established by adopting Miles and Hubemans formula, which amounted to 0.91. The exploration and findings revealed the need and implication of value education in the present scenario. Further-more, the data analysis revealed that value education is a process that begins at home and continues in society, and further, it continues in formal educational institutions. Conclusion. The study envisions that the educational institutions must integrate the curriculum with value education so that students cultural worlds, meanings they attribute to behaviour, events which essentially lead to the developmental process of the society. The National Education Policy 2020, aims to universalise education in India by 2025; it also aims at inter-and multidisciplinary approaches in Indian education. The pre-sent study juxtaposes an interdisciplinary approach to English and value education. 2021, Pro Scientia Publica Foundation. All rights reserved. -
Value Ingredients Private Limited: engaging farmers for achieving triple bottom line
Learning outcomes: After completion of this case study, students will be able to apply the triple bottom line concept to a spice manufacturing and export company (RBT 3); to examine the options before Value Ingredients Private Limited (VIPL), namely, to cultivate spices in the traditional way versus adopting integrated pest management (IPM) to cater to international markets (RBT 4); to analyse the returns for an IPM farmer vis-vis a conventional farmer, and to compare the returns therein (RBT 4); and to evaluate the ways and means of engaging farmers to change their way of cultivation (RBT 5) Case overview/synopsis: The COVID-19 pandemic heightened awareness about the benefits of spices and buoyed its demand worldwide, which presented an opportunity to VIPL, a spice manufacturing company based in Chennai, to expand its business. However, the export markets demanded residue-free spices grown with little or no use of pesticides. Traditional farmers supplying spices to VIPL were accustomed to spraying pesticides whenever there was a pest attack. This case study discussed the options that the protagonist Mr Sijil Karim, managing director and CEO of VIPL, had, who wanted to onboard farmers for pesticide-free cultivation. The options before him were either to continue traditional farming or adopt IPM. This case study discussed the merits, demerits and challenges of each of these options. The triple bottom line concept discussed three Ps people, planet and prosperity for this case as follows: The farmers and the consumers constituted the people in the spice supply chain. The farmers supplying organic, export-worthy spices under the guidance of VIPL gained 30% more than regular spice farmers, which were accrued through cost savings and better prices. The consumers benefitted from the pesticide-free, organic spices through accrued health gains. The manufacture of organic, pesticide-free spices helped the planet, as the process did not release hazardous chemicals into the atmosphere. VIPL manufactured pesticide-free spice with a focus on prosperity. Complexity academic level: The case study can be introduced in a course on sustainability while discussing the triple bottom line concept. This case study showed how a for-profit company grew without losing sight of the planet or its focus on people. This case is best suited for students who have preliminary knowledge of supply chain management, operations and sustainability. Therefore, it is suited for sophomore-year students of MBA. Supplementary materials: Teaching notes are available for educators only. Subject code: CSS 11: Strategy. 2023, Emerald Publishing Limited. -

Value addition to international students' exchange programs through engagement in services
Social responsibility has been an emerging concept in Higher Educational Institutions in India. Promoting social responsibility through international students' exchange programs helps students' capacity to improve their cultural, social and service knowledge to bring about sustainable and meaningful development. This chapter looks at the impact of the interventions of international students in slum communities, especially working with children and women for their academic, health and economic empowerment. This was a qualitative study using a self-structured interview schedule. Data were collected from twenty international students from universities of Norway and the Netherlands who were placed in urban slums for five years and thirty children and women from urban slums of Bangalore who benefitted from this program. A purposive sampling method was used, and the data were analyzed using thematic analysis. This chapter reveals the development of children and women through international students' programs and helps showcase further planning for innovative programs for vulnerable populations. Attitudes of both groups towards cultural differences and the expectation and effectiveness of the exchange program may also be described in this chapter. This chapter intends to help plan international exchange programs from different dimensions benefiting the slum communities for their development and sensitizing cultural differences from different perspectives. 2024 Nova Science Publishers, Inc. -
Value Addition for Technology Start-Ups Through Physical Co-Location
Numerous economic theories, knowledge, social, and communication theories have extensively explored the phenomenon of physical co-location in various contexts. However, limited scholarly attention has been given to co-location in emerging contexts such as co-working spaces, predominantly used by start-ups. One of the critical questions examined is how co-location adds value to technology start-ups in the early and growth stages of their development. We chose a premium coworking space in Bangalore, Indias start-up capital, as the studys research setting during January March 2020. The qualitative research employed semi-structured interviews to explore the phenomenon. Our findings revealed that start-ups actively used co-located resources to explore, experiment, and validate new business ideas in the early stage. As they transitioned into the growth phase, they exploited co-located industry networks to expand into new markets. They also learned vicariously from other co-located resources and used them to solve complex problems and refined their processes and routines. As start-ups begin to grow and expand, co-location infrastructure-related costs are not justifiable, operations are less secure, and the meta culture of the co-located environment is in conflict with the firms operating culture. The results of this study have the potential to be significant for technology start-ups that are exploring new ways of working and addressing uncertainties during the early and growth stages of their development. 2021, Associated Management Consultants Pvt.

Valorization of waste chilli stalks (Capsicum annuum) as a sustainable substrate for cellulose extraction: insights into its thermomechanical, film forming and biodegradation properties
Rising global population accelerates food waste generation, thereby creating a crisis in food waste management. A solution involves deriving value-added products like cellulose biopolymer from food waste. Chilli stalk wastes are one such food waste which are generated in large quantities and are unsuitable for field use or incineration due to health and environmental challenges. A greener alternative is extracting cellulose biopolymer from chilli stalk waste. The extraction of cellulose biopolymer from chilli stalk results in a renewable, biodegradable and economically efficient biomaterial with a broad range of applications. The extraction process involving alkali treatment (NaOH) and bleaching (alkaline H2O2), resulted in a yield of 29.85% cellulose biopolymer. The extracted cellulose was subjected to quantification and functional property analysis followed by characterization (FTIR, XRD, TGA, DSC and SEM) to analyse functional groups, crystallinity, thermal properties and surface morphology. Functional property analysis resulted in higher values when compared with commercial cellulose. The characterization techniques confirmed the effective removal of impurities such as lignin, hemicellulose and pectin by the chemical treatments. Cellulose sheets, fabricated using solvent casting, exhibited exceptional biodegradability (85.36%) within 20days, surpassing conventional food packaging materials, commercial food packaging paper (15.95 0.12% [%w/w]) and plastic sheets (7.89 0.33% [%w/w]) over the same time period. The novelty of this research lies in the innovative valorization of chilli stalk waste, which often remains unused in large quantities globally. This study introduces a cost-effective method to convert it into a value-added, highly biodegradable biopolymer. The resulting cellulose sheets provide an eco-friendly substitute for traditional food packaging materials. 2024, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. -

Valorization of pineapple peels through single cell protein production using saccharomyces cerevisiae NCDC 364
Background and objective: Pineapple peels contain significant quantities of carbohydrates, which can be used as cheap raw materials for production of commercially important products through fermentation. The aim of this study was to use this feed stock for the cultivation of Saccharomyces cerevisiae NCDC 364 and its use as single cell protein. Material and methods: The single cell protein was produced using discarded pineapple peels and Saccharomyces cerevisiae NCDC 364. Optimization of bioprocess variables (temperature, pH, incubation period, carbon source and nitrogen source) affecting single cell protein production was carried out using classical "one factor at a time" approach. The harvested cells from optimized media were screened for amino acid content using high-performance thin-layer chromatography. Results and conclusion: The Saccharomyces cerevisiae NCDC 364 produced maximum single cell protein in pineapple peel based media, compared to non-optimized media. The "one factor at a time" approach showed that the maximum biomass production was achieved at optimized levels of temperature of 25C, pH of 5, incubation period of 120 h, carbon source of 1% sucrose and nitrogen source of 0.5% beef extract. The amino acid profiling of the harvested biomass using high-performance thin-layer chromatography analysis revealed that tryptophan included a comparatively higher concentration of 6.52%, followed by threonine (3.25%). Results of this study suggest that easily available raw materials such as fruit peels offer cost-effective substrates for production of commercially important microbial proteins for alarming global issues linked to protein malnutrition.

Valorization of pineapple peel waste for fungal pigment production using Talaromyces albobiverticillius: Insights into antibacterial, antioxidant and textile dyeing properties
The present study explores natural pigments as sustainable alternatives to synthetic textile dyes. Due to their therapeutic applications and easy production, fungal pigments have gained attention. However, data on pigment production using solid-state fermentation and optimization is limited. Milk whey was used to grow Talaromyces sp., followed by an evaluation of pigment production in solid and liquid media. Pineapple peels were used as a cost-effective substrate for pigment production, and a one-factor-at-a-time approach was used to enhance pigment production. Pineapple peel-based media produced 0.523 0.231 mg/g of pigment after eight days of incubation. The crude pigment had promising antibacterial and significant antioxidant properties. The extraction fungal pigment's possible use as an eco-friendly textile dye was assessed through fabric dyeing experiments with different mordants. This work contributes to the valorization of agricultural waste and provides insight into using fungal pigments as sustainable alternatives to synthetic textile dyes. 2023 Elsevier Inc. -
Valorization of Fish Waste for Chitosan Production: A Sustainable Approach
Fish waste can be used as an ideal substrate for extraction of commercially important bio-polymers like chitosan. Chitosan is a versatile biopolymer with various biological and chemical properties such as biocompatibility, biodegradability and antimicrobial properties and can be a major applicant in different industries. The present research work focuses on extracting chitosan from fish scale waste through chemical extraction methods. Demineralization in this study is done using 1% HCl for 36 hours at 150 rpm and deproteinization is done using dilute 0.5N NaOH for 18 hours at 150 rpm. The final step deacetylation is done using a concentrated 40% NaOH solution at 90?C for 6 hours. The extracted chitosan had a yield of 12% per 100g of fish scale and characterization was done using FTIR, XRD, TGA and DSC. Further the possibility of fabrication of chitosan films followed by assessing their biodegradability will be the future scope of the work. The Electrochemical Society -
Valorization of bovine tannery fleshing waste as a fish meal replacer: a conceivable green approach
The study intended to utilize bovine tannery fleshing (BTF) a significant contributor of solid wastes in leather industries, in its unhydrolyzed form (raw fleshing flour [RFF]) as well as in fermented form (fermented fleshing flour [FFF]) as fish meal (FM) replacer in formulated aqua feeds. In line with this, experimental diets were formulated, characterized, and evaluated for their virtue. Improvement in the physical quality of diets was achieved with FFF incorporation, enabling better pelletability, palatability, and feed texture. As the formulated diets were of sinking type, feeding trials on column as well as bottom feeders were concertedly attempted, as a value-added application of proteinaceous feed ingredient (BTF) in aquaculture sector. FFF inclusion diets proved superior to RFF inclusion diets. Maximum protein and lipid retentions of 89% and 92% were evidenced. Fish feeding experiments disclosed the productive impact of substituting FM with FFF by 50 and 75% on the performance (fish growth) of Cirrhinus mrigala (19.03 cm final length, 112.89 g Kg-1 final body weight, and 99% survival rate) and Labeo rohita (22.19 cm final length, 214.99 g Kg-1 final body weight, and 97% survival rate) respectively, with enhanced muscle biochemical compositions. FFF inclusion diets best suited column feeders than bottom feeders, with acceptable feed conversion ratio (< 2) and about 65% and 69% of protein in Rohu and Mrigal, respectively after 90 days of feeding. Absence of feed related mortality and multimycotoxins in FFF inclusion diets authenticated its invulnerable nature, signifying the need of bacterial fermentation processes to pull out the maximum worth of the solid waste. Thus, bovine tannery fleshing (BTF) would probably be used as a relatively inexpensive, effectual, safe, and an absolute source of protein for marine animals, reinforcing aquaculture business to strengthen up its profitability and eventually; this is an assuring conscientious solid waste management strategy that could be scaled-up to develop high-quality aquaculture feeds. 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. -
Valorization of agro-industrial fruit peel waste to fluorescent nanocarbon sensor: Ultrasensitive detection of potentially hazardous tropane alkaloid
Millions of tonnes of agro-industrial waste are generated each year globally, with the vast majority of it going untreated, underutilized, and disposed of by burning or landfilling, causing severe environmental distress and economic downturn. A practical solution to this global issue is to use green chemistry to convert this waste into value-added products. Accordingly, in the present study, agro-industrial orange peel waste was valorized into fluorescent nanodiamond-like carbon sensor via a green route involving hydrothermal treatment of microwave carbonized orange peel waste. The developed sensor, used for the fluorescence detection of potentially hazardous drug atropine sulfate, exhibits unique dual linearity over concentration ranges of 300 nM to 1 M and from 1 M to 10 M, as well as ultra-low sensitivity of 34.42 nM and 356.46 nM, respectively. Additionally, the sensor demonstrates excellent reproducibility, high stability, and satisfactory recovery when used to identify and quantify atropine sulfate in biological samples and commercially available pharmaceuticals, indicating promising multidisciplinary applications.

Valorisation of coffee husk as replacement of sand in alkali-activated bricks
The coffee industry is known to generate voluminous amount of waste during its production process. Different types of waste such as coffee hush ash and spent coffee ground, to name a few, have been extensively researched as a substitute in the construction industry. However, the utilization of coffee husk as a substitute for construction materials has seen limited exploration. In particular, there are no studies which investigate the utilization of waste coffee husk (WCH) in alkali-activated bricks. Therefore, in this research WCH was employed as a substitute to sand in alkali-activated bricks. Alkali-activated bricks were synthesized with ground granulated blast furnace slag (GGBFS), fly ash (FA), sand, and sodium silicate solution (SS). Sand was replaced with WCH at replacement rates of 0 %, 5 %, 10 %, 15 %, 20 %, and 30 % by volume. The developed bricks were evaluated for strength, density, water absorption, porosity, and efflorescence. Additionally, structural and morphological characteristics of bricks were assessed by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA), and Scanning electron microscopy (SEM) analysis. The results indicate that bricks with WCH improve the compressive strength with a maximum value of 15.7 MPa, and reduce the density with a minimum value of 1509 kg/m3 for composites with 30 % WCH, respectively. The water absorption and porosity of bricks increased with incorporation of WCH due to porous structure of WCH. The physico-chemical analysis of the bricks shows effective geopolymerization in the composite system with WCH, and further the bricks with 30 % WCH depict thermal stability with insignificant weight loss at 575 ?. Finally, the composites with 30 % WCH classify as good quality bricks as per IS 1077: 1992 specifications, and this will improve practical feasibility of such materials in the construction industry. 2024 The Authors -

VALIDATION OF CONTINUOUS FLOW METAL PLATE REACTORS IN THE TERPENE KETONE SYNTHESIS BY ALCOHOL OXIDATION
The present study elucidates the oxidation of alcohols to terpene ketones using dichloro(p-cymene) ruthenium (II) dimer catalyst by continuous flow process using a metal plate reactor. The synthesized products were separated and validated using GC, GCMS,1 H-NMR, and13 C-NMR techniques. The reaction process exhibited product yield in the range of 80-95% on a scale of 1-80 grams. Optimization studies were conducted to calibrate the reaction conditions to improve the product yield. The scope of the reaction was explored using aromatic, cyclic, and aliphatic alcohols under optimized conditions, which resulted in high yields of terpene ketones. A reaction mechanism is proposed for the oxidation of alcohols by a continuous flow process. The significant advantages of the current protocol include synthesis at mild conditions, safer handling of reagents, flexibility to tune reaction conditions, and straightforward scale-up in the range of 1-80 grams with high efficiency and reproducibility. 2024, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.

Vacuum annealed tin sulfide (SnS) thin films for solar cell applications
Thin films of tin sulfide (SnS) were grown on a glass substrate at an optimum temperature of 300 C by thermal evaporation technique. Following the deposition, films were vacuum annealed at different temperatures in the range of 100 to 300 C for 2 h. The effect of annealing temperature (Ta) on the composition, surface morphology, microstructure, optical and electrical properties was investigated. Elemental analysis showed sulfur deficiency of annealed films and the Sn to S atomic percent ratio increased from 1.0 to 1.1. XRD analysis confirmed the orthorhombic crystal structure of the films with (111) preferred orientation and phase purity. Degree of preferred orientation decreased with increase in Ta and the diffraction peaks corresponding to other planes intensified. Increasing the Ta to 300 C led to an increase in crystallite size to 129 nm. Results indicated presence of several crystallites in the grains of as-deposited films. AFM studies revealed the fragmentation of larger grain and the average grain size reduced form 265 nm for as-deposited films to 132.8 nm for the film annealed at 300 C. An apparent shift in absorption edge towards longer wavelengths is observed for films annealed at Ta > 200 C. The optical constant such as optical band gap, extinction coefficient (k), absorption coefficient (?) and refractive index (n) have been evaluated. The optical band gap of SnS thin films varied marginally with the annealing temperature and remained in between 1.331.29 eV. The extinction coefficient of the film annealed at 300 C was enhanced and is found to be 0.85 at 700 nm. At the annealing temperature of 300 C, the SnS films had enhanced electrical properties: the electrical resistivity was 7.8 ? cm, the p-type carrier concentration was up to 2.17 1016 cm?3, and the mobility was about 36.9 cm2V?1s?1. The variation of physical parameters with Ta has been explained by taking into account the crystallite size and the presented values are discussed with relevance to solar cells. 2017 Elsevier B.V. -
UVIT view of NGC 5291: Ongoing star formation in tidal dwarf galaxies at ? 0.35 kpc resolution
NGC 5291, an early-type galaxy surrounded by a giant H I ring, is believed to be formed from collision with another galaxy. Several star forming complexes and tidal dwarf galaxies are distributed along the collisional ring which are sites of star formation in environments where extreme dynamical effects are involved. Dynamical effects can affect the star formation properties and the spatial distribution of star forming complexes along the tidal features. To study and quantify the star formation activity in the main body and in the ring structure of the NGC 5291 system, we use high spatial resolution FUV and NUV imaging observations from the Ultraviolet Imaging Telescope onboard AstroSat. A total of 57 star-forming knots are identified to be part of this interacting system out of which 12 are new detections (star forming complexes that lie inside the H I contour) compared to the previous measurements from lower resolution UV imaging. We estimate the attenuation in UV for each of the resolved star-forming knots using the UV spectral slope ?, derived from the FUV - NUV colour. Using the extinction corrected UV fluxes, we derive the star formation rate of the resolved star forming complexes. The extinction corrected total star formation rate of this system is estimated as 1.75 0.04 M? yr-1. The comparison with dwarf galaxy populations (BCD, Sm, and dIm galaxies) in the nearby Universe shows that many of the knots in the NGC 5291 system have SFR values comparable to the SFR of BCD galaxies. 2023 The Author(s).
