Consequences of non-appearance before the international court of justice: debate and developments in relation to the case Nicaragua vs. Colombia
Authors: Arévalo-Ramírez Walter , Sarmiento-Lamus Andrés
Published: September 2022

The article analyzes the non-appearance before the International Court of Justice motivated by the turbulent reception by the Colombian Government of the 2012 and 2016 sentences of the I.C.J in the cases between Nicaragua and Colombia, with the objective of establishing the consequences of such conduct. Methodologically, the jurisprudence that has applied Article 53 of the Statute, and the different consequences of nonappearance in cases before the Court are studied. Through an analysis of jurisprudence the document discusses the nature of non-appearance, its effects on the sentence, the agents, the applicable law, the evidence and the procedure, to conclude that, although non-appearance is a behavior allowed to the State Parties, it is in general detrimental to its procedural interests, its defense of the case and the administration of international justice as a system, especially in such technical cases as those related to maritime delimitation and liability in relation to alleged violations of sovereign rights and maritime spaces.

La prescripción de servidumbres de transmisión y de distribución de energía eléctrica
Authors: Echeverría-Molina Judith Sofía , Nieto-Ariza Luis José
Published: September 2022

Este artículo tiene como objetivo analizar la figura de las servidumbres eléctricas y su posibilidad de ser adquiridas por prescripción a partir de lo establecido en el artículo 939 del Código Civil colombiano, norma que dispone que las servidumbres continuas y aparentes puedan adquirirse bajo esta figura. Este trabajo tiene como finalidad reflexionar sobre este conflicto jurídico, doctrinal y jurisprudencial existente en el ordenamiento jurídico colombiano, respecto a la posibilidad de adquirir, por prescripción, servidumbres de transmisión y de distribución de energía eléctrica. Es preciso establecer que este estudio gira sobre dos figuras del derecho civil como son: la prescripción y servidumbres; y sobre el servicio público domiciliario de energía eléctrica. Estas nociones han sido estudiadas de manera separada pero, al combinarse y aplicarse al régimen de las servidumbres de transmisión y de distribución de energía eléctrica, evidencian un interesante aspecto de controversia, y de distintas posturas doctrinales y jurisprudenciales.
El valor de la jurisprudencia en el derecho mercantil colombiano
Authors: León-Robayo Édgar Iván
Published: September 2022

El Código de Comercio establece en sus nueve primeros artículos cuáles son las fuentes del derecho mercantil colombiano. Sin embargo, la entrada en vigencia de la Constitución Política de 1991 y los pronunciamientos de la Corte Constitucional han traído consigo modificaciones directas al sistema jurídico que orienta el derecho comercial, abriendo paso a la constitucionalización y la aplicación de la teoría del precedente judicial. Este artículo tiene por objeto determinar claramente cuál es la verdadera ubicación de la jurisprudencia en la escala de fuentes del derecho mercantil en Colombia, para precisar su ubicación como fuente principal y auxiliar, siguiendo los criterios que para tal efecto ha determinado la Corte Constitucional.

Authors: Pabón Giraldo Liliana Damaris , Jiménez Henao Daniela , Mazuera Zuluaga Andrés Gustavo
Published: September 2022

El presente artículo identifica la forma como las sociedades tipo BIC en Colombia se pueden convertir en una empresa social y así brindar una nueva óptica al derecho comercial. Para su desarrollo se empleó una metodología teórica y analítica, en donde a través del estudio de la ley y de las experiencias de otros países frente a este tipo de sociedades se analiza el tema, se abordan los vacíos existentes y se genera una propuesta. Para tal efecto se parte del estudio de las sociedades BIC creadas en Colombia por medio de la Ley 1901 de 2018 y reglamentadas mediante el Decreto 2046 de 2019. Luego se realiza un análisis frente al tema en países tales como Estados Unidos, Reino Unido, Italia y España, en donde se evidencia que las mismas tienen mayor desarrollo y cuentan con incentivos que no existen en nuestro país. En consecuencia, este artículo realiza una invitación para el país respecto de la implementación de incentivos en las sociedades BIC, tomando como base los planteados desde la experiencia internacional, para ello propone: la implementación de beneficios tributarios, mayor facilidad para contratar con el Estado, mayor apoyo bancario, beneficios para los trabajadores de esta sociedad y mayor agilidad en el procedimiento de certificación como B Corporation; pues solo así se podrá dar real efectividad a la normativa creada y sedinamiza el derecho comercial en el país.

Cultivating Urban Storytellers: A Radical Co-Creation to Enact Cognitive Justice for/in Self-Built Neighbourhoods
Authors: Ortiz Catalina
Published: September 2022

We all carry an imperative to imagining collectively more just cities, to engaging more meaningfully with multiple urban actors and their different sensibilities through their stories. Storytelling helps to foster empathy, to understand the meaning of complex experiences, and, most importantly, to inspire action. With the rise of the digital era and new technologies at hand, we have an opportunity to redefine not only the way we tell, connect, and engage with our collective stories, but also how we work together in forming them. Based on the research design project Patrimonio Vivo | Living Heritage, grounded in the city of Medellín, this article illustrates the dynamics and potentials of co-creation with cultural organizations and creative teams through learning alliances. Our alliance among a cultural community centre, a cooperative of architects, a grassroot organisation and post-graduate students around the world used storytelling to propel an ecology of urban knowledges. Working online during the global lockdown, we mobilised stories of solidarity, care, memory, and livelihoods through the narrative of people, places, and organisations following their trajectories as the basis for the design of spatial strategies. This collaborative work aimed at contributing to the recognition of everyday spatial practices in self-built neighbourhoods as a form of “living heritage” of the city and a key building block for reframing a more progressive “integral neighbourhood upgrading” practice. I argue that using storytelling as a co-creative methodology, based on learning alliances, we can bridge the ecology of urban knowledges to foster cognitive justice and transform the current stigmatizing urban narrative of self-built neighbourhoods.
METHODS AND TOOLS FOR STIMULATING THE INNOVATION ACTIVITY OF SMALL ENTERPRISES IN THE RUSSIAN FEDERATION
Authors: Koneva A. A.
Published: September 2022

The article considers theoretical approaches to the identification and systematization of methods and tools of state stimulation of innovation, and provides an overview of foreign practice. In world practice, various methods of stimulating innovation activity are used, both economic and organizational and legal. The current system of stimulating the innovation activity of small enterprises in the Russian Federation is systematized and analyzed. As a result, problems were identified at the level of financial and non-financial methods. In terms of financial methods, there is a bureaucratic procedure for obtaining financing, difficulty in obtaining preferential loans, poorly developed preferential taxation, the venture capital investment market is practically not developed, difficulties in attracting private investment through online platforms, etc. Among non–financial methods there is a lack of information about possible support tools, insufficient use of tools that stimulate cooperation of participants in the innovation process. It is concluded that it is necessary to create an organizational tool – a meeting place for participants in the innovation process to solve the problem of transferring innovation from a research center or university to a corporation.

Authors: Ongarbayev Yerdos , Baigulbayeva Moldir , Tileuberdi Yerbol , Zhumakhan Kairat
Published: September 2022

In the paper the sorption capacity of shungite rocks of the Koksu field (Kazakhstan) in relation to the oil from the Karazhanbas and Tengiz fields (Kazakhstan) were studied. Oil spills occurring during production, gathering, transportation, storage and refining, and repair work on wells are an urgent environmental problem. There are effective methods of soil purification, including particular interests addressed to sorption process. The aim of this research is to study oil sorption by shungite rocks of the Koksu deposit after mechanochemical activation. The mechanochemical activation of shungite rock samples was carried out in a planetary ball mill at different speeds of rotation and ratios of ball mass to the sample. The developed sorbents based on shungite rocks of the Koksu deposit were tested for cleaning samples of oil-contaminated soils and their sorption capacities under dynamic and static conditions were determined. For the sorption of oil, the sorbent based on shungite of shale grade (TS) after mechanochemical activation is recommended, which sorption capacity under dynamic conditions is 2.57-2.85 g/g. Sorption of oil from 10 % of oil contaminated soil samples with the sorbents based on shungite after mechanochemical activation showed sorption capacity of 0.44-0.45 g/g in 60 days under static conditions. The practical significance of the research lies in the prospects of using shungite rocks to clean up oil spills.

Published: September 2022

The presence of sand particles flowing along with reservoir fluids in a pipeline increases the probability of pipeline failure. The risk of pipeline failure is either accentuated or abated by the flow conditions of the fluids in the pipeline. In this study, a quantitative risk analysis of the effect of sand on pipelines during multiphase flow, under the pipeline failure modes; sanding up, erosion, and encountering abnormal pressure gradient was conducted. Three piping components were considered: line pipe (nominal size 1.5 in [3.8 cm]), swing check valve (nominal size 12.007 in [30.5cm]) and 90 deg LR Elbow (nominal size 2.25 in [5.7cm]). Correlations that indicate the critical velocities and the critical sand concentrations above/below which these failures occur were employed and implemented in a Visual Basic program. The analysis was conducted at a temperature of 204 °C and pressure of 604 psi [4.2×106 Pa]. A probability distribution, simulating real-life scenario was developed using Monte Carlo simulation. This determines the probability of deriving critical sand concentration values that fall beyond the set statistical limits which indicates the probability of occurrence of the failure being investigated. For all three failures, the severity of occurrence (represented by CAPEX incurred in solving the failures) was multiplied with the probability of failure which gave rise to the risk indexes. Based on the histogram plot of average risk index and analysis, the study reveals that larger diameter components are prone to turbulence which lead to greater risk of erosion. The risk of abnormal pressure drop and sanding up were considerably lower than that for erosion (abrasion).

AIM: To estimate clinical manifestation of decreased ovarian reserve in women of reproductive age from Eastern Siberia.
MATERIAL AND METHODS: A total of 1119 women aged 18 to 40 years who underwent an annual preventive medical examination at their place of work were invited to participate in a cross-sectional study performed in 20172019 in Irkutsk Region and Buryat Republic (Russia). Among the 1119 women, 907 aged 31.785.13 years were included in the study, after which clinical, instrumental, and laboratory research methods and statistical analysis were utilized. Among the 907 women included in the study, 117 (12.9%) had 5 follicles per ovary and were diagnosed with decreased ovarian reserve (DOR). The laboratory study showed that 56 of the 117 (47.8%) women had an antimullerian hormone (AMH) level below 1.2 ng/mL, the average value of which was 0.530.43 ng/mL.
RESULTS: In women with reduced AMH levels, a shortening of the menstrual cycle (p=0.0187) and high parity were observed. Moreover, premature ovarian failure was diagnosed in 4 of the 117 (3.4%) patients with a reduced number of antral follicles.
CONCLUSION: The frequency of women with DOR in the Eastern Siberia region based on one AFC criterion was 12.9%. Only 3.4% of women satisfied all criteria for premature ovarian failure. The average age of women with signs of DOR in this region was 35.123.87 years and did not depend on ethnicity. Moreover, 47.8% of the women with an AMH 1.2 had a follicle-stimulating hormone (FSH) level of 12.14 ME/mL, while 52.2% of the those with AMH 1.2 had a FSH level of 5.91 ME/mL. Patients with AMH 1.2 can be characterized by high parity in the anamnesis and shortening of the menstrual cycle.
Critical Proximity
Authors: Kruth Jeffrey , Keslacy Elizabeth
Published: September 2022

The architecture curriculum is usually divided into studio courses and lecture or seminar courses where design and research, respectively, are separately pursued. Although the curriculum is designed to unite the approaches of design, the humanities, and the sciences that together comprise the architectural endeavor, in practice these epistemological forms of inquiry are divided into separate courses and rarely allowed to crossover into one another. Two structures common to architecture programs avoid these divisions: the community design center and the research studio. The first unifies design with community engagement and exposure to the real-world issues of marginalized communities, while the second incorporates humanities-based research into the studio. In this paper, we will present the work of a three course-sequence recently taught at Miami University as a “Humanities Lab” that pursued methodological promiscuity by mixing community-based research and design. In so doing, we jettisoned the expertise traditionally claimed by architecture to create a more inclusive practice–inclusive of community members and their expertise and centering the experiences and histories of marginalized people instead of buildings. We do so by engaging in what Eyal Weizman has called “critical proximity,” in which the distanciated position of the researcher is jettisoned in favor of working alongside and for marginalized communities. Over the course of three semesters, we explored the impact of critical proximity in three different endeavors–a seminar, research studio, and exhibition design–and discovered inclusive pedagogical strategies: thickness, research-in-community, and decentered production. Together, these strategies allowed us to refigure the role of the architect as a researcher aligned with community interests.

Published: September 2022

Marburg virus disease (MVD) is a highly fatal disease caused by the Marburg virus (MARV) which belongs to the family Filoviridae. The disease has been recently reported from Ghana, an African country, and nearly 15 outbreaks of MVD have been reported in the past five decades. Various species of bats viz., Rousettus aegyptiacus, Hipposideros caffer, and certain Chiroptera act as the natural source of infection. Pathophysiology of the disease reveals severe antiviral suppression due to changes in gene expression and interferon-stimulated gene (ISG) production in the hepatic cells. With the progression of the disease, there may be the development of pain in the abdomen, nausea, vomition, pharyngitis, and diarrhea along with the onset of hemorrhagic manifestations which may lead to the death of a patient. The advent of molecular detection techniques and kits viz., reverse transcription polymerase chain reaction (RT-PCR) kit has greatly aided in the diagnosis of MVD. Identification of the virus in the specimen with great accuracy can be done by whole viral genome sequencing. The use of a combination of MR-186-YTE (monoclonal antibody) and an antiviral drug named remdesivir in the NHP model is greatly effective for eliminating MARV. The protective effect of a Vesicular stomatitis virus (VSV) (recombinant) - based vaccine expressing the glycoprotein of MARV has been revealed through animal model studies, other vaccines are also being developed. Proper health education, personal hygiene and precautions by health care workers while handling patients, good laboratory facilities and service along with the establishment of enhanced surveillance systems are the need of the hour to tackle this highly fatal disease. This article presents an overview of different aspects and salient features of MARV / MVD, and prevention and control strategies to be adopted.
Application of Fungi as Meat Alternatives in Industry: Mini Review
Authors: Kok Kee Wong , Hock Ong Ghim , Yee Sabrina Ling Shuet , Er Loh Kyle
Published: September 2022

Human consumption has outpaced meat production and manufacturing due to the rising human population and limited land for livestock agriculture. Meat consumption can have negative effects on human health, but meat production can negatively affect the environment by causing global warming and water pollution. Hence, this study produces the idea of using fungus as an alternative to replacing meat. Fungus is an ideal choice as a meat replacement because it has high nutritional content and a fast growth rate. The main objective of this review was to assess the nutritional potential of nine fungal species namely Fusarium venenatum, Neurospora intermedia, Tuber sp., Xerocomus badius, Ganoderma lucidum, Pleurotuseryngii, Agaricus bisporus, Pleurotus sajor-caju and Lentinula edodes and to determine which species is the best candidate for meat replacement. The nutritional values, toxicity, and growth rate of each fungus were assessed. Comparative data analysis suggests that F. venenatum, N. intermedia, P. eryngii, A. bisporus, P. sajor-caju, and L. edodes are found suitable for producing fungi-based meat.

Published: September 2022

The present study aimed to synthesize the magnesium doped ferric sulphate nanoparticles (Mg-Fe2SO3 NPs) and investigate their seed germination efficacy. Mg-Fe2SO3 NPs were prepared by a simple and cost-effective method and subjected to characterization. The X-ray Diffraction (XRD) spectrum revealed the crystalline nature of Mg-Fe2SO3 NPs with an average crystallite size of 36.41 nm. The field emission scanning electron microscope (FESEM) image displayed the agglomeration of Mg-Fe2SO3 NPs with the shape of the grains appeared like starfish which has limbs grown from a common cluster. The energy dispersive X-ray spectroscopy (EDS) demonstrated the existence of C (10.5%), O (49.14%), Fe (26.67%), Mg (0.78%) and S (13.35%) elements in Mg-Fe2SO3 NPs. It also revealed the absence of impurities in the synthesized NPs. Through Fourier transform infrared spectroscopy (FTIR), Mg-Fe2SO3 NPs showed the characteristic peaks at 615.29cm-1, 1130.29cm-1, 1400.32 cm-1and 1633.71cm-1 which corresponded to Fe-O, C-N, O-H and N-H vibration respectively. Further, the seed germination study revealed that the Mg-Fe2SO3 NPs treatment caused a significant increase in seedling growth of cowpea (Vigna unguiculata) seeds compared to the untreated samples.

Authors: M Suganthi , R Logeshwaran , G Abirami , B Rupa Shree , P Anandaraj , P Senthilkumar
Published: September 2022

Hibiscus rosa-sinensis is a widely grown evergreen valuable medicinal, ornamental species planted in India. Scale insects are small herbivorous insects found on all continents and they are serious sap sucking pests of many ornamental plants. These scale insects are undetectable due to their tiny size, basic morphology, and polyphagous feeding nature. Hence, the management of these tiny insects become a serious concern across the globe. To afford a prospective solution to the problem, an accurate, simple, and developmental-stage-independent identification method is required, hence this study attempted the molecular identification of scale insect in Hibiscus rosa-sinensis using mitochondrial gene Cytochrome Oxidase Subunit I (mtCOI) sequencing. The experiment was carried out by isolating insect DNA using a modified CTAB method. Through two or three rounds of error-prone PCR followed by a steady procedure to amplify a mtCOI region. This region of mtCOI has been used as a standard DNA barcode for a diverse array of taxa. The confirmation has been done by sequencing of mtCOI which suggest the highest similarities with Eulecanium giganteum. This study addresses the questions of biodiversity and molecular characterization of scale insects. Further, the information obtained in this study provides baseline data for future crop improvement programs and integrated pest management strategies.

Published: September 2022

Low adaptive capacity and oxidative stress are the factors leading to cellular dysfunction, protein and lipid peroxidation, and the development of diseases. In recent decades, there has been a trend toward the active use of plant-based antioxidants. Trifolium pratense L. is a promising plant for the pharmaceutical and food industry and has anti-radical properties. This work is devoted to studying the antiradical and oxidative stress-released properties of T. pratense in Caenorhabditis elegans under oxidative and temperature stress. The objective of this research was to evaluate the anti-radical properties of the T. pratense extracts and individual BAS (chlorogenic acid, ononin, biochanin A, genistein) and analysis their influences on the oxidative stress of Caenorhabditis elegans in the presence of paraquat. Analysis of the antiradical properties revealed that chlorogenic acid has the maximum ability to neutralize the free radical (35.49µmol). A separate analysis of oxidative stress revealed high ononin activity at concentrations of 10, 50, and 100 µmol at 48 hours of cultivation.  Biochanin A increases survival by 13.1% compared to the control. The use of the extract (500µmol) contributed to an increase in survival on day 1 of incubation. Under conditions of thermal stress, ononin (50 and 200 µmol) has a positive effect on the viability of C. elegans.  The extract and BAS of T. pratense are characterized by high antiradical activity. In addition, the ability to influence the viability of C. elegans was revealed. Therefore, it is worthwhile to further study the biological properties of T. pratense for use in geroprotective therapy.

Published: September 2022

Mosses have long been used in traditional Chinese medicine due to the presence of secondary metabolites which have shown high biological activities. In particular, these secondary metabolites have demonstrated effective antibacterial activity against pathogenic microorganisms. In this study, the influence of different extraction solvents on the antibacterial activities of the Polytrichum commune was carried out using the disc diffusion method. Results showed that both 12.5 mg/mL of methanol moss extract and 6.25 mg/mL of ethanol moss extract were the most effective concentrations against Bacillus cereus and Pseudomonas aeruginosa. Additionally, the P. commune extracts were included as an added ingredient in soap bases to produce antibacterial soap prototypes where the effectiveness of the soaps containing the extracts in removing microorganisms from actual test individuals was carried out. Results of the thumb impression test of test individuals showed that the growth of microbial reduced after washing hands with the usage of both liquid and solid soap with the addition of P. commune extracts. Moreover, the antibacterial soaps performed better in eliminating microorganisms in comparison to control soaps without P. commune extracts. Taken together, P. commune extract could be a good candidate as a value-added ingredient utilized to produce antibacterial soaps due to its antibacterial properties.

Introduction to NJWLS 2022-3
Authors: Buch Anders
Published: September 2022

The third issue of volume 12 of Nordic Journal of Working Life Studies brings four new research articles and a book review.The first article of this issue is authored by Helena Håkansson: Contradictions of Ordered Trust: Trust-based Work and Conflicting Logics in Municipal Care. In this article, Håkansson explores the implementation of a trust-based development project in the social care service in a municipal district in Sweden. The research took place in 2017–2019 and comprised semi-structured interviews and observations among managers and staff involved in the project. Using an institutional logics framework to interpret and discuss the findings, Håkansson illuminates how a managerial logic and a logic of care manifests themselves, and how the logics relate to power structures in the organization. She shows how the managerial logic tends to relativize trust into a question of financial accountability, and highlights the inherent paradox of ordering trust as a one- way communication by the upper management.
Bearing Fault Classification using Empirical Mode Decomposition and Machine Learning Approach
Authors: Manjunatha G. , Chittappa H. C.
Published: September 2022

Industrial machinery often breakdowns due to faults in rolling bearing. Bearing diagnosis plays a vital role in condition monitoring of machinery. Operating conditions and working environment of bearings make them prone to single or multiple faults. In this research, signals from both healthy and faulty bearings are extracted and decomposed into empirical modes. By analyzing different empirical modes from 8 derived empirical modes for healthy and faulty bearings under different fault sizes, the first mode has the most information to classify bearing condition. From the first empirical mode eight features in time domain were calculated for various bearing conditions like healthy, rolling element fault, outer and inner race fault. The feature extraction of vibration signal based on Empirical Mode Decomposition (EMD) is extensively explored and applied in diagnosis of fault in rolling bearings. This paper presents mathematical analysis for selection of valid Intrinsic Mode Functions (IMFs) of EMD. These chosen features are trained and classified using different classifiers. Among them K-star classifier is most reliable to categorize the bearing defects.

An Artificial Intelligent Prediction Model For Evaluating The Engine Performance And Emission Characteristics Using Waste Cooking Oil Biodiesel Blends
Authors: Mamilla Venkata Ramesh , Sreedhar S. Bhagavan , Krishna Padilam Rama
Published: September 2022

Bio-fuels or bio-diesels are biodegradable fuels and are not toxic in nature. In this study, bio-fuels are produced by transesterification process from waste oils of cooking, animal fat and vegetable oils. During the process, these oils are reacted with an alcohol generally ethanol or methanol in the presence of sodium hydroxide as catalyst resulting in ester called as bio-diesel with a byproduct of glycerin. The manufactured pure bio-diesel is generally less flammable when compared to diesel and having burning point of 50 degrees celsius. Bio-diesel blends are formed by combination of bio-diesel and petroleum diesel in different proportions and the flash and gel points lie between those of pure fuels depending on the mixture. Artificial neural networks (ANNs) are soft computational models that mimic the behaviour of human neurons. ANNs are formed by the interconnections between the building blocks called neurons which are simple processing units that process the data and the performance of network depends on parameters involved and the architecture used. These are used for obtaining the correlation between the dependent and independent process parameters that are nonlinear in nature. ANNs find application in classification and prediction problems, provides results that are fast and are very close approximation to actual output. This study indicates bio-diesel is produced from waste cooking oil methyl ester and various blends are made with different proportions of bio-diesel and petroleum diesel. The experiments are conducted on diesel engine with bio-diesel blends and the performance parameters are brake power (BP), specific fuel consumption (SFC), brake thermal efficiency and the engine exhaust emissions. The ANNs are trained with the partial blend data used for experimentation as input to the model and the performance parameters as output using different activation functions. The model is tested with the remaining data to assess the percentage error between the actual and predicted values. The results reveal that blends of bio-diesel provide good performance and emission characteristics. It is concluded from the study that the ANN model can predict the exhaust emissions and engine performance well.

The stability of a horizontal sparsely packed porous layer of a ferromagnetic fluid heated from below is examined when the fluid layer is subjected to time-dependent magnetic field modulation. The effects of the oscillating magnetic field are treated by a perturbation expansion in powers of the amplitude of the applied field. The onset criterion is derived based on the condition that the principle of exchange of stabilities is valid. The stability of the system, characterized by a correction Rayleigh number, is computed as a function of magnetic, porous parameters and the frequency of magnetic field modulation. It is found that the onset of magnetic field modulated ferroconvection can be delayed or advanced by controlling these parameters. The effect of various parameters is found to be significant for moderate values of the frequency of magnetic field modulation. The problem throws some light on external means of regulating convection in ferromagnetic fluid applications.

Natural fibre reinforced polymer (NFRP) is a renewable, recyclable and biodegradable polymer found in many industrial applications. Few among many naturally available plants which are categorised under natural fibre reinforced polymer such as jute, pineapple, cotton hemp, coir, sisal, banana, bamboo, ramie and kenaf. These plants are found to be rich in lingo cellulosic fibres and hence they are often used as reinforcement for composites. Among these plants, jute is the most commonly available natural fibre in third world countries and recognised as the second most important fibre in the world. It has found its vast applications as a decorative and furnishing material. In the present study, an effort has been made to investigate one of the critical and most influential vibration characteristics of one such natural reinforced polymer, jute fibre polymer composite. In this investigation, the jute fibre has been fabricated with unsaturated polyester resin and maleic anhydride and the experimental trials were conducted for varying percentages of maleic anhydride using Fast Fourier transform. The damping factor for each trial was computed and analysed to retrieve the vibration characteristics of jute fibre polymer.

This endeavour also entails developing novel materials for composites that are superior to existing composites. Lapox L-12 resin, E glass fibre material, and cerium oxide, which are the rare earth material family member in the periodic table. The combination of these materials was utilised to investigate the wear loss, and surface roughness in a dry sliding wear in two conditions: with and without postcuring (at 100oC for 60 minutes) with process parameters such as percentage of filler material, normal load and sliding speed. The experiments were planned according to L16 orthogonal array based on Taguchi design. Results reveal that wear loss and surface roughness is minimum in post-cured glass fiber reinforced polymer (GFRP) composites compoared to without post-cured specimens. The optimum process parameters level for minimum wear loss of post-cured GFRP composites, optimum process parameters are percentage of filler material is 20%, load is 15N and sliding speed is 0.25 m/s.

Fracture is a new failure mode due to unstable propagation of a delamination crack growth in composite structures caused by applied load. The efficient characterization of the crack growth in composite structures enhances to estimate the duration of life. This paper mainly focusses on characterization of the fracture toughness of GFRP/epoxy matrix with SiO2 filler form of composites and studying the crack behaviour in the (Mode II) ENF specimen which leads to interlaminar fracture in structural applications. The laminates are arranged to specify the Mode II interlaminar fracture toughness and interlaminar shear strength of GFRP/ epoxy matrix, GFRP/5% wt SiO2, GFRP/10% wt SiO2, using ASTM D7905 M-14 and JIS test methods. The results show that unfilled SiO2 GFRP/epoxy matrix composites are of more facture toughness; the result reveals that the JIS methods in plane shear Mode II test were lower value of fracture toughness than that of ASTM D7905 M-14 Mode II test. As recommend in ASTM standard, ENF (shear pre-cracked) specimen is applicable to measure Mode II fracture toughness.

Published: September 2022

The classical linear stability analysis is used to examine the effect of thermal radiation on the onset of Darcy-Brinkman ferroconvection. The boundaries of the fluid layer are treated as black bodies and the optical properties of the transparent ferromagnetic fluid are independent of the wave length of radiation. The fluid and solid matrix are assumed to be in local thermal equilibrium. Considering realistic boundary conditions, the principle of exchange of stabilities is shown to be valid and the critical values pertaining to the stationary instability are obtained by means of the higher order Galerkin method. It is observed that the basic temperature profile turns out to be exponential and symmetric as the radiative parameters increase and that the effect of thermal radiation is to delay the onset of Darcy- Brinkman ferroconvection. The destabilizing influence of magnetic forces is affected by the radiative parameters. The effect of magnetic, radiative and porous parameters on the convection cell size is also discussed.

Published: September 2022

The high temperature corrosion and wear of steels in coal based power plant at elevated temperature is the primary reason behind downtime in power generating plants. The failure of steel components is big hazard to the effectiveness of the power-plant and responsible for the economic loss. To counter the effect of environmental degradation on steels, the chemical composition has been improved and their microstructures are also modified. But these changes have provided limited protection to the steels. The other useful method to control the degradation of steels is to apply coating of the protective material on the surface of target metal with the help of thermal spray technology. In this article, a systematic study of literature has been done to understand the level of protection provided by the HVOF (thermal spray technique) sprayed coatings to the different steels employed in degrading environments in coal based power plant. This article may help to researchers to select the HVOF technique with best coating combination to resist the failure of steels in coal based power plants.

Efficient heat recovery from low-grade heat sources is an achievable scientific frontier in the coming decade. One of the promising technologies in waste heat recovery is the organic Rankine cycle (ORC) system. Major obstacles to low-grade heat recovery include economic viability, scale, system efficiency, and exergy efficiency. In low temperature ORC systems, the cost of condenser becomes significant and hence air-cooled condenser is a feasible option. However, the performance of the air-cooled condenser is sensitive to the variation in ambient air conditions. India, being a tropical country, have villages and cities whose average temperature varies from -2oC in winter to 50oC in summer. The present work involves the study of heat transfer effects on the condenser using common organic working fluids and quantifying the consequences of environmental temperature variations. The constant thermal evaporator load is supplied with a medium-enthalpy heat source at 100 and 150oC. The atmospheric temperature associated with heat rejection from the condenser is varied from 273K to 313K for 5 working fluids. A MATLAB model of the ORC system is developed to study the effect of condenser performance on the first and second law efficiency of the ORC system. The MATLAB model is used to investigate the effect of varying inlet temperatures of the working fluid on the performance of ORC system to choose an organic working fluid suitable for Indian climatic conditions. R365 mfc, and R1233zd exhibit higher expander work and show higher heat rejection. At higher heat source temperatures of 150oC, the simulation shows a higher second law efficiency for the working fluid R1224yd(Z), which has critical temperature closed to the heat source temperature.
