Effect of Stocking Density on the Post-larval Production of Macrobrachium rosenbergii in A Two-Phase Larval Rearing System
Authors: Pillai Bindu R. , Rao K. J.
Published: November 2023

The effect of stocking density on the post-larval production of Macrobrachium rosenbergii has been studied. A two-phase larval rearing technique involving high-density rearing of early larvae for 10-12 days followed by low-density rearing of advanced larvae (stage VI) was followed. In the first phase of rearing, the stocking density did not show any effect on survival. However, in the second phase of rearing, percentage of survival decreased with increasing stocking density. Post-larval production per litre was found to be maximum at a stocking density of 55/1, and both higher and lower stocking densities resulted in decreased production per litre of the medium.
Content and Composition of Organic Matter in Some Sewage-Treated Fish Pond Soils in Relation to Productivity
Authors: Saha P. K. , Manda L. N.
Published: November 2023

The organic matter content and its composition in relation to primary productivity of soil in 12 sewage-treated fish ponds were studied. Organic carbon contents of the soils were fairly high, ranging between 1.02 and 3.85%. The amount of humus carbon, on an average, constituted 23.7% of the total organic carbon. The carbon content of humic and fulvic acids of the soils ranged from 0.066 to 0.222 and 0.210 to 0.560%, respectively, constituting, on an average, 27.7 and 72.3%, respectively, of the total humus carbon. Primary productivity of the pond was found to be significantly correlated with total organic carbon, humus carbon, and humic acid and fulvic acid carbon contents of the soils.

Authors: Aluko P. O. , Aluko J. F. , Aremu A.
Published: November 2023

Tetraploidy was successfully induced in Clarias anguillaris. Hatchability in tetraploids ranged between 50% and 70%, and above 95% in diploid control. About 80% and 100% of the tetraploid and diploid fry survived in the first seven days, respectively. Tetraploids showed better growth performance (12.61 g) but not significant compared to 11.2 g for the diploid. Metaphase chromosome complement of tetraploid was 108 and diploid was 54. About 20% of cells in tetraploid preparation showed 3n and 2n chromosome complements. About 1% phenotypic abnormalities were recorded after hatching in tetraploid but absent in the control.

Authors: Routray P. , Routray M. D.
Published: November 2023

Studies were carried out at the low saline (2-7%%) brackishwater areas of Chilka lake. Three experiments were set to explore the culture possibilities of grass carp, Ctenopharyngodon idella in terms of growth and survival, effects of pen rearing system and control of a brackishwater weed, Potamogeton pectinatus by biological means. Three pens, having an water area of 0.5 ha each, were barricaded by knitted bomboo strips ( 5 - 1 5 111111 dia) and the space between the strips were 8 - 10 mm. The grass carp were stocked at the rate of 1200, 600 and 300 nos/ha in pens I, II and I I I , respectively, for a period of 62 days without fertilization, manuring and artificial feeding. It was noticed that the aquatic weed served as a good source of feed for the grass carp. The survival in pens I, II and III were 68.6%, 87.2% and 58.3%, respectively. The growth rate of grass carp was 1.69 g/day in pen I, 1.61 g/day in pen II and 3.6 g/day in pen III

Authors: Mahapatra B . C . , Nayak G. B.
Published: November 2023

Toxic effects of ripe fruit pulp of hingan, Balanites roxburghii, containing saponin on fishes Glossogobius giurus, Chanda nama, Sarotherodon mossambica and Channa marulius have been evaluated in the laboratory. A dose 0.04 g/I killed all the fishes within 24 hours of exposure. C. marulius was found more resistant to the toxic effect of hingan fruit than the other three fishes. The possibilities of using hingan fruit pulp for eradication of weed and unwanted fishes from the culture ponds are also reviewed.

Published: November 2023

Incidence of large-scale mortality of cultured shrimp due to white spot disease caused by the white spot syndrome virus (WSSV) has been recorded from the confined rain-fed pond culture system in Haridas and Kusubenti villages of Chilka Lake, Orissa (India). Gross signs and symptoms of the disease and behavioural changes in shrimp were observed. Some of the soil and water quality parameters have been analysed and no adverse conditions could be observed. Detailed histopathological observations made on the moribund shrimp indicated the presence of WSSV. The probable source of the disease transmission in the confined culture system is discussed.

Aflatoxicosis due to acute toxicity was studied through two experimental trials conducted on Indian major carp, Catla catla using crude as well as pure aflatoxin B. In the first experiment where fishes were fed crude toxin mixed with diet @ 5 mg/kg, no clinical sign as mortality could be observed, whereas in the second experiment where pure aflatoxin B was fed with the diet @ 0.5 mg/kg resulted in 40% mortality with signs of lethargy, listlessness and excess mucus secretion. Histopathological alterations in the liver, kidney, spleen, heart and gastrointestinal tract have been described and discussed.
Fatty Liver Disease (Lipoid Liver Degeneration) of Indian Major Carps and Its Management
Authors: Mishra B. K.
Published: November 2023

Fatty liver disease was observed in some of the private fish ponds around Bhubaneswar. Affected specimens, mostly, Catla catla were having the disease in varying degrees. There was mortalitv at advanced stages of the disease. On an examination of live as well as freshly dead specimens, the liver of the affected fish was found to be damaged due to fatty infiltration of hepatic cells. However, externally the fish appeared normal. Fish fed with poor quality feed with rancid fat developed the disease which could be successfully controlled by withdrawing the rancid feed and providing fresh feed with high protein (about 22%) content.

Authors: Das P. C. , Rath R. K.
Published: November 2023

Effect of intraperitoneal injection of different inducing agents viz., pituitary gland (PG) extract, PG + domperidone (DOM), PG + pimozide (PIM) (all in two split doses) and ovaprim (in single dose) on ovulation and spawning in three Indian major carps such as rohu, catla and mrigal were investigated. Injection of PG extract alone to rohu, catla and mrigal resulted in ovulation of 93.3, 90.6 and 100% individuals, respectively. The spawning success achieved was 91.6, 71.8 and 100% in rohu, catla and mrigal, respectively. PG at the same dose alongwith dopamine antagonist (DOM/PIM) resulted in ovulation in all the individuals of the three species of carp but partial spawning to complete spawning was observed in them. The present study revealed that the domperidone alongwith hormonal suspension is more effective in rohu and mrigal, while pimozide with hormonal suspension is more effective in catla.

Authors: Paul B. N. , Sarkar S. , Mukhopadhyay P. K.
Published: November 2023

Rohu fingerlings (average weight 5.24 ± 0.46 g) were reared for 8 weeks on four totally plant protein based test diets of which control diet (T-I) consisted of soybean meal, groundnut cake and rice bran. In other three diets, mustard cake (roasted) was incorporated at 3 different proportions replacing soybean meal and groundnut oil cake. The fishes were maintained in triplicate treatment groups having 10 fishes in each in a flow-through system fitted with fiber glass tanks (60 I capacity) with a flow rate of 1.5 1/h. Stored ground water was used for fish rearing. The diets were isonitrogenous and isoenergetic. The growth performance was significantly higher (P < 0.01) in T-I; there was no difference in growth between T-2 and T-3 groups, and growth performance was significantly lower in T-4 groups. The feed cost (Rs/kg) were 9.15, 8.50, 8.10 and 7.90, respectively for T-1, T-2, T-3 and T-4. It may be concluded that roasted mustard cake can be incorporated up to 35 per cent (w /w) in carp diet.
Effect of Water Transparency on the Growth of Black Tiger Shrimp,Penaeus monodon
Authors: Mohanty R. K.
Published: November 2023

The present study was carried out at "Shrimp Culture Pilot Project", Chandipur coast of Orissa, India, during 1995-1996 to study the role of water transparency on water quality and growth of Penaeus monodon under semi-intensive culture system. It was observed that satisfactory range of average daily growth (ADG) of P. monodon achieved when transparency ranged between 29-35 cm in winter and 30-45 cm in summer. Influence of water transparency on various stages of growth was highly significant (P < 0.01) under semi-intensive culture system. Irrespective of stocking density, high growth rate was mostly obtained during 60-100 days of culture when transparency ranged between 37 ± 8 cm. Growth rate was low at high and low transparency probably due to low nutrient content and high organic load with maximum daily fluctuation of pH (>1.0) and dissolved oxygen (8.1-10.6 mg/1), respectively.

Authors: Rangacharyulu P. V. , Sarkar S. , Mukhopadhyay P. K.
Published: November 2023

A study was conducted to know the vitamin A requirement of rohu (Labeo rohita) fry. Rohu fry of average initial weight 0.27g were fed with purified diets containing 0, 1000, 2000, 3000 and 4000 IU vitamin A/kg diet for a period of 120 days under laboratory conditions. Vitamin A unsupplemented diet served as control. A significantly (P < 0.05) higher growth of 1.72 g was obtained in fish fed with diet containing 2000 IU/kg vitamin A. The lowest FCR of 2.52 was recorded in the same group. The study indicated that vitamin A can be added @ 2000 IU/kg diet for rohu fry to achieve better growth and feed efficiency.

Published: November 2023

Integration of aquaculture in vast rainfed waterlogged lowlands can be an acceptable option for improvement of farm productivity and income in the country, particularly in the easter India. An adaptable technology on rice-fish, prawn, vegetable, fruits and other crops diversified farming system called Rice-fish System· has been developed at Central Rice Research Institute, Cuttack for waterlogged rainfed lowlands (Sinhababu and Venkateswarlu, 1995). Studies on the food and feeding habit of fish in this system is an important aspect for optimizing the fish productivity. Some information is available on the plankton profile of the irrigated rice field mainly (Saha and Ramakrishna, 1962; Li and Pan, 1992) and deep water ecology (Das et al., 1991) and also in shallow rainfed rice-fish seed system (Sinhababu et al., 1992), but not in the rice-fish system. We studied the seasonal changes in the zooplankton population in the system.
Some Observations on Phytoplankton Bloom, Water pH and Dissolved Oxygen in Aerated Shrimp Ponds
Authors: Mohanty R. K.
Published: November 2023

The purpose of water quality management is to create a good and stable aquatic environment for the growing shrimp so as to obtain the optimum possible yield in the shortest possible time, and to attain a healthy and dynamic symbiotic environment. Maintaining optimum levels of physico-chemical parameters and their balance induce growth of shrimp, while fluctuation impairs the ecology and its balance, causes stress, deterioration and negative effects on shrimp. When, among all the hydrological parameters, pH and DO are considered as most critical for shrimp growth and survival. Phytoplankton plays a significant role in stabilizing the whole pond ecosystem, in minimizing the fluctuation of water quality and lowers the levels of NH,, HS, etc., which are toxic to shrimp. Since growth, survival and yield of Penaeus monodon depend largely upon the water quality, it is essential to maintain a stable water colour and to understand the role of these variables in shrimp pond ecosystem, where aquatic environment is artificially controlled by periodic liming, water exchange and aeration.

An Overall View of Different Taxonomical Parameters for Identification of Fishes
Authors: Mukhopadhyay S. K. , Bose A. K.
Published: November 2023

For identification of fishes, different taxonomical (conventional and non-conventional) parameters of usage have been reviewed here. Among non-conventional parameters, cytotaxonomical and chemotaxonomical parameters have been discussed. All the scientists in the field of cytotaxonomy and chemotaxonomy of fishes have advocated to use cytotaxonomical and chemotaxonomical parameters as additional tools for the characterisation and classification of fishes. Till to-day, classification of the fishes are mainly based on conventional parameters. A fool-proof classification of the fishes in the world as far as practicable is demand of the day, basing on both conventional and non-conventional parameters.

Published: November 2023

Fatty acid composition of six freshwater microalgae namely, Anabaena cylindrica (AN), Enteromorpha intestnalis (El), Gracillarin edulis (GE), Nostoc salbasa (NS), Spintlina platensis (SP) and Westleopsis prolifica (WS) was determined in the present study. The algal species were collected from their natural habitat and the pure strain of each algae was obtained through repeated sub-cultures in agar medium. The cultures were maintained in their respective media with an illumination of 2,200 Lux at the upper glass surface at 24 ± 2 °C and 12:12 h light:dark cycle. Cells were harvested during their log phase. Saturated fatty acid (SAFA) of C16 (16:0, palmitic acid) and C18 (18:0, stearic acid) chain lengths were found to be dominant in the fatty acid profile of all six algae. Cyanophytes (AN, NS, SP and WS) were found to be rich in 16:ln7 MUFA (monounsaturated fatty acid) while, Chlorophyte (El) and Rhodophyte (GE) contained relatively high amount of 18:ln7 and 24:ln9 MUFAs, respectively. Spirulina being completely devoid of n3 PUFA (polyunsaturated fatty acid) contained substantial quantity of gammalinolenic acid (18:3n6) which was absent in other algae. The n3/n6 ratio for Westleopsis was found to be much higher (2.07) as compared to other algal groups.

Published: November 2023

A feeding trial of 60 days duration was conducted on rohu fingerlings (2.70 ± 0.06 g) to develop a diet having least polluting effect vv'ith respect to ammonia in the ambient water. Nine practical diets with 20, 30 and 40% crude protein, and 3 energy levels (300, 335 and 370 kcal/100 g) per each protein level were prepared. The medium protein and high energy diet (30% protein and 370 kcal energy/100 g) showed significantly higher growth and nutrient utilization compared to other groups. Dissolved ammonia load was less in low and medium protein diets compared to high protein diets. The study demonstrated that diet having 30% protein and 370 kcal energy yield optimum growth compared to high protein and high energy diets in rohu accompained by reduced nitrogenous waste discharge.
Effect of Feeding Schedule on the Growth, Feed Efficiency and Body Composition of Young Indian Major Carps, Catla (Catla catla) and Rohu (Labeo rohita)
Authors: Das Nityananda , Mishra Kirti , Samantaray Kasturi
Published: November 2023

Fingerlings of catla (Catla catla), average weight 1.4 ± 0.3 g and rohu (Labeo rohita), average weight 1.7 ± 0.3 g, were held under laboratory condition for 56 days and fed a test diet at a rate of 4% of their body weight daily either at 0730 h (MF), 1600 h (AF) or half ration at both these times (TF). The feeding time conducive to total growth (0730 h) differed from that conducive for the deposition of protein and fat in the muscle (1600 h), for both the species. The food conversion ratio and protein efficiency ratio were same for MF and TF of rohu and these were better at TF than MF for catla. Feeding schedule appeared to be an important factor in determining the growth and metabolic fate of the nutrients in these major carp species.
Seasonal Reproductive Activity in the Ovaries of the Cirrhinus mrigala (Hamilton)
Authors: Trehan Nirupma , Garg S. K.
Published: November 2023

The Indian major carp, Cirrhinus mrigala, is a seasonal breeder and spawns during monsoon season. On tlie basis of ovarian weights and histological studies, the ovarian cycle has been divided into four phases: (i) Postspawning period or the resting phase, (ii) Preparatory period, (iii) Prespawning period and (iv) the spawning period. Three types of primary oocytes have been identified in the stained ovarian sections, viz., stage 1 non-yolky oocytes, stage II vitellogenic oocytes and stage III yolky oocytes. Maximum ovarian weights were recorded during June-July, while maximum plasma vitellogenin titers were observed during May. Ova diameter was maximum during July and minimum during November-December. Morphological changes observed during follicular development include the appearance of many nucleoli and development of egg envelops. Yolk nucleus or Balbiani's vitelline body, a highly basophilic structure was observed adjacent to the nuclear envelope, which subsequently moved towards the periphery and finally disintegrated. Following vitellogenesis, the germinal vesicle (GV) migrates from a central position to the oocyte periphery and thereafter where subsequently it disappears. The phenomenon is called oocyte maturation. Theca, follicular epithelium and zona radiata surround the growing egg, A micropyle in zona radiata internus was also identified in the yolky and ovulated oocytes. A progressive decrease in the diameter of zona radiata, thinning and withdrawl of microvilli and stretching of the evelope perhaps appear to expell the egg resulting in ovulation.

Published: November 2023

Three experiments were conducted with golden mahseer (Tor putitora Ham.), snow trout (Schizothorax richardsonii) and Chinese carps to study the effect of supplemental vitamins on growth, survival and feed conversion efficiency (FCE). The test diets were prepared by adding Vit. A (8000 lU/kg), Vit. E (100 lU/kg) and Vit. C (400mg/kg) to the basal diet comprising soybean meal, groundnut oil cake, fish meal, rice bran and vitamin-mineral premix and fed at 5-10% body weight of the fish. The golden mahseer and snow trout recorded significantly higher (p < 0.01) weight gain of 21.4-46.2 and 142.5-317.3%, and 4.57-10.80 and 2.58-5.25% better feed conversion efficiency (FCE) in the vitamin supplemented diets than that of control diet. Survival of golden masher was not affected by supplementation of vitamins, whereas in snow trout it was significantly higher. Among Chinese carps, only common carp recorded significantly (p < 0.01) better weight gain (27.6-78.6%) in the vitamin-supplemented diets than that of control diet. Grass carp and silver carp did not show any significant difference in growth, survival and FCE in the vitamin-supplemented diets. It is concluded that the combination of Vit. A+E-i-C has significant effect on growth and FCE in golden masher, snow trout and common carp.
Rearing of Carp of Fry and Post-Larvae of Freshwater Prawn in Simulated Seasonal Waterlogged Condition of Different Depths
Authors: Mohanty Rajeeb K.
Published: November 2023

The study was carried out to explore the possibility of raising carp fry to advanced fingerlings stage alongwith post-larv'al rearing of freshwater prawn, in simulated waterlogged conditions of various depths. Growth performance of all species improved with increase in water depth, probably due to less mutual competition for food and space that cause physiological stress and relatively stable water quality. With the increase in water depth from 20 -110 cm (T1-T4), the productivity increased significantly (524.4 - 1051.3 kg/ha/120 days). However, the percentage increase in productivity reduced from 32% (T1-T2) to 20.5% (T3-T4) probably due to higher survival rate and density-dependent growth.
Study of the Soil Properties and the Bentonite Clay to Reduce Water Loss from the Fish Ponds
Authors: Srivastava Sanjeev Kr , Mahanta P. C. , Singh A. K. , Ram Babu
Published: November 2023

Water loss from the fish pond due to seepage and percolation has been the major problem of farm managers in the semi-arid and arid regions. The soils of such regions have been characterized for low clay content, deep water table, high CaCO3 and high potential evaporation. This leads to very high water loss rates from the fish ponds. In an effort to overcome the problem of water loss, an experiment was conducted at the farm site of National Bureau of Fish Genetic resources, Lucknow. The experiment was conducted in eight pits (total surface area 57.44 m2 and volume 30.34 m2), which were divided into two groups, each consisting of four pits. The first group was having high CaCO3 and other was having low CaCO3. Composite sample were taken from these pits and were analyzed for texture, bulk density, true density, pH, CaCO3 and organic carbon. The readings on daily water loss and on pan evaporation rate were recorded in relation to clay, silt, sand and CaCO3 and also after application of bentonite treatment. The results showed marked reduction in . water loss after application of a coating of 5% bentonite and 95% local soil mixture. The seepage rate was much higher in the pits having higher CaCO3 content. It was concluded from this study that presence of CaCO3 content of the soil increase the water loss which requires treatment to reduce the water percolation to a manageable level in a fish farm.

Giaime Pintor, Leonello Vincenti e Teatro tedesco
Authors: Basili Maurizio
Published: November 2023

In February 1941, through the mediation of Leone Traverso, German literature expert Giaime Pintor began a productive collaboration with the publisher Bompiani. He had already worked as an editorial consultant for Einaudi and agreed to work for Bompiani on two volumes in the “Pantheon” series, directed by Elio Vittorini. He then translated some texts for the anthology Germanica and assembled a “collection of plays and comedies from the origins to the present day”, titled Teatro tedesco. This essay analyzes the structure and critical principles of this anthology, as well as the human, commercial and political circumstances that led to the inclusion of certain authors and translators, or the exclusion of others.
Carlo Bo e Narratori spagnoli
Authors: De Benedetto Nancy
Published: November 2023

Carlo Bo’s anthology, Narratori spagnoli, is conceived for high-brow readers and constitutes a meeting point for editors and publishers promoting a novel conception of literary circulation and marketability. Bo’s project reflects the new perception of Spain that circulated in Italy after the Civil war and the killing of Federico García Lorca, marking the definitive distancing of Italian intellectuals from fascism. Since the 1930s, the Italian literary field showed a preference for Spanish authors and texts in line with the cultural scenario of the time and prefiguring future change. Narratori spagnoli deviates from previous Spanish works published mainly to entertain readers and adopts a diachronic perspective that also includes unknown or forgotten authors, thereby laying the foundations for a more systematic cultural project.
Leone Traverso e Germanica
Authors: Sisto Michele
Published: November 2023

Germanica was published in 1942, concomitantly with Elio Vittorini’s Americana, and shows the negotiation of three dominants (Jakobson): first, the editorial one, i.e. Valentino Bompiani and his invention of the anthological series “Pantheon”; the second dominant, the political one, was the fascist censorial politics, which proved particularly restrictive towards German literature. Third, the literary dominant was represented by Leone Traverso, the editor and an acknowledged hermeticist, and Elio Vittorini, “Pantheon” director and promoter of a new realist poetic. Despite its innovative potential in the Italian repertoire of German literature, Germanica, differently from Americana, did not succeed in establishing as a post-war literary manifesto.
Linking genotypic and phenotypic changes in the E. coli long-term evolution experiment using metabolomics
Authors: Favate John S , Skalenko Kyle S , Chiles Eric , Su Xiaoyang , Yadavalli Srujana Samhita , Shah Premal
Published: November 2023

Changes in an organism’s environment, genome, or gene expression patterns can lead to changes in its metabolism. The metabolic phenotype can be under selection and contributes to adaptation. However, the networked and convoluted nature of an organism’s metabolism makes relating mutations, metabolic changes, and effects on fitness challenging. To overcome this challenge, we use the long-term evolution experiment (LTEE) with E. coli as a model to understand how mutations can eventually affect metabolism and perhaps fitness. We used mass spectrometry to broadly survey the metabolomes of the ancestral strains and all 12 evolved lines. We combined this metabolic data with mutation and expression data to suggest how mutations that alter specific reaction pathways, such as the biosynthesis of nicotinamide adenine dinucleotide, might increase fitness in the system. Our work provides a better understanding of how mutations might affect fitness through the metabolic changes in the LTEE and thus provides a major step in developing a complete genotype–phenotype map for this experimental system.
Replication of “null results” – Absence of evidence or evidence of absence?
Authors: Pawel Samuel , Heyard Rachel , Micheloud Charlotte , Held Leonhard
Published: November 2023

In several large-scale replication projects, statistically non-significant results in both the original and the replication study have been interpreted as a “replication success”. Here we discuss the logical problems with this approach: Non-significance in both studies does not ensure that the studies provide evidence for the absence of an effect and “replication success” can virtually always be achieved if the sample sizes are small enough. In addition, the relevant error rates are not controlled. We show how methods, such as equivalence testing and Bayes factors, can be used to adequately quantify the evidence for the absence of an effect and how they can be applied in the replication setting. Using data from the Reproducibility Project: Cancer Biology we illustrate that many original and replication studies with “null results” are in fact inconclusive. We conclude that it is important to also replicate studies with statistically non-significant results, but that they should be designed, analyzed, and interpreted appropriately.
Addressing SDG16.2: Eliminating violence towards children – An applied theatre approach
Authors: Gregorzewski Moema , O'Connor Briar , O'Connor Peter
Published: November 2023

We offer a case study of a long-running Aotearoa New Zealand-based applied theatre programme, Everyday Theatre. As both academics and Everyday Theatre practitioners, we explore how the programme addresses the aspirations of the United Nations’ Sustainable Development Goal (SDG) 16.2, which is centred on eliminating violence towards children. Our reflections are informed by the qualitative data collected in our ongoing discussions as facilitators, our reflective journals, teacher evaluations of the programme, and a series of collaborative research workshops. We investigate the role and place of the drama conventions of teacher-in-role, pre-text, aesthetics, and framing. They are potent constituents of participatory theatre practice that can provoke both students and teachers to collaboratively conceptualise themselves and each other as active, responsible, critical, and empathetic agents for social change. These explorations throw light on how applied theatre practice can form small but significant contributions to engendering opportunities for students and teachers to consider how they could change their own future narratives, creating more socially cohesive local communities, and, in this way, addressing SDG 16.2.

The UN Sustainable Development Goal 4 (SDG4) addresses equal access to quality education, focusing on literacy, numeracy and the science-field STEM subjects (Science, Technology, Engineering, Mathematics), - seemingly forgetting the importance of developing practical skills like craftsmanship. STEAM includes Arts into STEM, where the arts represent several independent artistic forms including music, theater, dance, visual arts, crafts and so on.
In this article we focus on education for sustainable development through craftsmanship in embroidery. In a transdisciplinary collaboration that includes art, craftsmanship has its own innate value. Our research question is: In which ways can creative collaboration in embroidery enhance a sustainable STEAM education learning experience?
We attempt to find answers to this by looking into how STEAM collaboration may affect the ways we teach craftsmanship, and the challenges and opportunities of doing so in a holistic transdisciplinary project, with a focus on ecological sustainability.
Three groups of teacher-students help examine how crafts may contribute in building ecological awareness in themselves and an audience through conveying meaningful artistic narratives. Their embroideries were inspired by the UN’s Decade of Ecosystem Restoration. The results were shared through the Global Science Opera, an international STEAM-education initiative.
Our analysis of the research data is influenced by posthumanizing creativity, which emphasizes ethically contributing world citizenship through embodied, collaborative creativity between creator and creation. This journey of making and being made shows a reciprocal relationship between humans and non-humans. The slow-art of embroidery invites the students into an embodied dialogue with the materials, tools, techniques and the scientific topics in the transdisciplinary context. As researchers we wonder how this dialogue and in-depth experience affected the students’ attitudes and actions towards sustainability. We found that the data supports the embodied, co-creative embroidery process, that it improved the students' craft experience, as well as increased the understanding and respect for the challenges in the new eco-reality.

Life below water, as well as at waters, is threatened due to human activity that has caused global warming. As UNESCO stresses, “the time to learn and act for our planet is now”. This article reports on a literature review of existing action research on water education, ocean literacy and arts integration carried out by an emerging interdisciplinary research group stretching across the fields of marine science, arts and science education. Joined by a concern for water education and ocean literacy, the interdisciplinary teams screened 368 research articles with the assistance of the program Covidence which helps with streamlining the literature review processes in a team. Ending up with 14 relevant articles that were analysed in-depth, the authors argue that arts-integrated water education projects take place locally across higher education, formal education and informal education in collaborative teams. The action research projects screened promote and develop open-ended, inquiry-based and creative pedagogies, seeking to foster the capacity to act for sustainable living in a more-than-human world. However, all research projects screened in the review seemed to develop water education more generally. There is a lack of literature researching how the connection to ocean literacy including life below water specifically, can be nurtured.

For the past decade, RESEAU has been engaging with Indigenous and rural communities across Canada in pursuit of water-health equity. RESEAU consists of a team of engineers, community partners, industry groups, and government officials working together to develop innovative solutions for water-health in small communities. Over the last six years, RESEAU has partnered with the UBC Research-based Theatre Lab to develop Treading Water, a research-based theatre play that brings to life some of the rich stories discovered during these community collaborations. The play flows between the intersecting narratives of individuals in a community dealing with unsafe drinking water and explores the resulting challenges to their health and well-being. Water operators and their experiences are central in Treading Water, and the research-based play illustrates their pivotal role in the community. This article, like the theatre initiative described, aims to open conversations addressing water quality and health issues facing rural communities in the 21st century. The article shares the collaborative process of developing the play with the various partners, the short script, as well as feedback from a performer and an evaluator.

Authors: Bergaust Kristin
Published: November 2023

The video works A Ship with a View and The Kitchen Garden were made during 2010 at the M/S Innvik, run by Nordic Black Theatre. This turned out to be the last year of the ship’s existence as an intercultural creative environment in the urban development Bjørvika. The works are created as montages with contributions of music, art and performance from people connected to the M/S Innvik. It shows glimpses of activities on board and the changing surroundings.  This work pertains to the Sustainable Development Goal no 11: “Make cities and human settlements inclusive, safe, resilient and sustainable, and partly to the SDG no 7: “Clean and affordable energy”. It also suggests culture should be included in sustainability discourse.

Censorship Crisis
Authors: Hallová Jana
Published: November 2023

The following research studies the use of memes on the social platform Twitter with regards to celebrity representation. Specifically, it analyzes two memetic posts by Elon Musk and the representation tactics behind them, using elements of multimodal analysis and critical discourse analysis. Subsequently, the study looks at the reception of these posts via comparative content analysis with custom classification to determine how successful the tactics behind these posts are and whether there is any evidence observable in the reception regarding censorship on Twitter after its purchase by Elon Musk. The comparative study comes in a form of quantitative analysis of the first 150 responses to each of the two posts. The study does not only demonstrate instances of attempts at diminishing the distance which the inherent power of a celebrity personage on social media creates, but also how successful these attempts are and whether they manage to distract the audience from the personage in question and their power over them.

The integration of Internet of Things (IoT) technologies, particularly the Internet of Medical Things (IoMT), with wireless sensor networks (WSNs) has revolutionized the healthcare industry. However, despite the undeniable benefits of WSNs, their limited communication capabilities and network congestion have emerged as critical challenges in the context of healthcare applications. This research addresses these challenges through a dynamic and on-demand route-finding protocol called P2P-IoMT, based on LOADng for point-to-point routing in IoMT. To reduce congestion, dynamic composite routing metrics allow nodes to select the optimal parent based on the application requirements during the routing discovery phase. Nodes running the proposed routing protocol use the multi-criteria decision-making Skyline technique for parent selection. Experimental evaluation results show that P2P-IoMT protocol outperforms its best rivals in the literature in terms of residual network energy and packet delivery ratio. The network lifetime is extended by 4% while achieving a comparable packet delivery ratio and communication delay compared to LRRE. These performances are offered on top of the dynamic path selection and configurable route metrics capabilities of P2P-IoMT.

Background

To analyze individually and interactively critical risk factors, which are closely related to low bone mineral density (BMD) in patient with ankylosing spondylitis (AS).

Methods

A total of 249 AS patients who visited China-Japan Friendship Hospital were included in this training set. Patients with questionnaire data, blood samples, X-rays, and BMD were collected. Logistic regression analysis was employed to identify key risk factors for low BMD in different sites, and predictive accuracy was improved by incorporating the selected significant risk factors into the baseline model, which was then validated using a validation set. The interaction between risk factors was analyzed, and predictive nomograms for low BMD in different sites were established.

Results

There were 113 patients with normal BMD, and 136 patients with low BMD. AS patients with hip involvement are more likely to have low BMD in the total hip, whereas those without hip involvement are more prone to low BMD in the lumbar spine. Chest expansion, mSASSS, radiographic average grade of the sacroiliac joint, and hip involvement were significantly associated with low BMD of the femoral neck and total hip. Syndesmophytes, hip involvement and higher radiographic average grade of the sacroiliac joint increases the risk of low BMD of the femoral neck and total hip in an additive manner. Finally, a prediction model was constructed to predict the risk of low BMD in total hip and femoral neck.

Conclusions

This study identified hip involvement was strongly associated with low BMD of the total hip in AS patients. Furthermore, the risk of low BMD of the femoral neck and total hip was found to increase in an additive manner with the presence of syndesmophytes, hip involvement, and severe sacroiliitis. This finding may help rheumatologists to identify AS patients who are at a high risk of developing low BMD and prompt early intervention to prevent fractures.

Chronic Kidney Disease (CKD) progression is associated with an increased risk of bleeding due to various reasons, some of which are iatrogenic. Bleeding at unusual sites, such as the iliopsoas muscle, is difficult to suspect as awareness about this condition is sparse, and the literature about the reasons for this condition is unclear. Iliopsoas bleed continues to be an enigma, and herein, the authors present a case series of three cases of spontaneous iliopsoas haematoma. The first case was a 64-year-old male with acute coronary syndrome and CKD on dual antiplatelet agents who had an iliopsoas bleed after dialysis. The second patient was a 51-year-old male with end-stage renal disease on Maintenance Haemodialysis (MHD) who bled into the iliopsoas after anticoagulation for Coronavirus Disease-2019 (COVID-19) related illness. The third patient was a 52-year-old female who had a Catheter-Related Bloodstream Infection (CRBSI) and Atrial Fibrillation (AF) requiring anticoagulation, and she developed an abdominal wall haematoma extending upto the iliopsoas. The authors highlighted the sudden occurrence, challenges in diagnosis and management of iliopsoas bleed in CKD, with a stress on the careful use of anticoagulation.

In the current scenario, Nosocomial infections (NI) due to environmental contamination in shared settings of health care, are a serious public health issue affecting millions of people every year worldwide. Therefore, this study aims to create a microbiological profile of high touch areas of Critical and Non-Critical units in Teaching Hospital of Madhya Pradesh. This Cross-sectional Study deals with bacterial (aerobic and anaerobic) surveillance and its antimicrobial susceptibility testing which will aid in enlisting antimicrobial-resistant bacteria and guide us in the use of antimicrobials judiciously. A total of 128 samples were taken from Critical care units and non-Critical units from eight surface locations classified into categories of immediate patient environment and commonly used equipment. These samples were then processed for isolation and identification by standard methods. Out of 128 samples, 28 (21.8%) samples were culture positive for aerobic only and none for anaerobic bacteria. Among which more culture positive samples were isolated from non-Critical units 53.5%, topping the list of contamination were General Medicine ward and Gynecology ward (17.8 %). The majority of isolated microorganisms were Staphylococcus aureus of which 38.4% were MRSA. It showed maximum resistance for Ampicillin (AMP) and was most sensitive to Gentamicin (GEN). Present study highlights that control of Staphylococcus aureus infection (including MRSA) in hospitals is essential. It can be achieved by proper implementation of hospital infection control measures and regular surveillance activity.
