Authors: Abraham Thankam K , Somaraj Anej
Published: May 2023

Brandon Reynolds addresses issues of environment in his editorial cartoons and the paper aims to unravel how he manipulates the conventions of the medium for public awareness and opinion formation. Both the formal and thematic aspects of the cartoons are analysed. Reynolds’ cartoons are an ample testimony of how cartoons hold their own as literary texts in the dissemination of ideas. The paper discusses how they serve as texts of ecocriticism. Since the medium has not much been brought under ecocritical analysis like poems and novels earlier the unique features of cartoons are focused. The dynamics of verbal and visual components are brought under study. The ecological and historical aspects are discussed.
SHILPA GUPTA: AN ARTIST CONCEPTUALIZING WITH TECHNOLOGY
Authors: Babbar Akshi , Singh Gurcharan
Published: May 2023

India follows the catchy, trendy, uncertain, and spontaneous concepts of new media art for the last few decades. New media practice in India has dealt with issues of identity, critiques of violence, narrative, and performance, and other subjects that come under the umbrella of new issues. New media art began to appear in India since the inception of the 21st century, but it showed in the works of artists like Vivan Sundaram, Nalini Malam, Ved Nayar, Rummana Hussain in the 1990s. New media ideologically mixed art with scientific craft, which resulted in an amplified narrative of our country and world that is a union of different creative languages. New media create a futuristic ethos in the art that is developing every second. It is a medium that symbolizes freedom of mediums, as it is spontaneous and enough. In all this, Shilpa Gupta came as a ‘blind star and star blind’.Shilpa Gupta is one of the leading contemporary, influential, and critically acclaimed new media artists of India’s new generation of international artists. A transcultural artist even when influenced with regional specificity. She considers new media art (a web of technology) as a key part of today’s existence, and, ensuing, prefers various forms of cutting-edge technology as the vehicle for her interactions with the viewer. Although Gupta’s works are developed largely through technological means their significance lies in their candid communication, the various issues that shape contemporary life, particularly the lives of young and adults. Her work is often coded with meanings that are not always instantly available but require the efforts of the viewer. Uniquely and humorously, Gupta reminds us of the danger of taking for granted – that it is indeed technology that connects us to the world. She is an artist who deals with her viewers, her audience is 70 percent part of her artwork. She brings reality from a new perspective.
SOCIAL METAPHORS IN THE INSTALLATION ART OF CONTEMPORARY INDIAN WOMEN ARTISTS
Authors: Negi Neetu , Singh Gurcharan
Published: May 2023

Art can be manifested and interpreted by artists to express and transcend changes in their surroundings, as well as showcases tragedies. Art can be used as one of the parameters which broaden our insight towards society. Artists examine social atrocities such as dysfunctional systems, criminal injustices, curbs on the freedom of expression, and childhood traumas which may be embedded in the artists’ minds. Art is the mirror of society and both modernists and post-modernists have tended to demonstrate communal riots and political unrest at the time of global distress. Meanwhile, in the contemporary art world, art is represented with bleak and abject constructions of contemporary subjectivity where, artists basically tend to depict themes such as political issues and reforms, ecological evils, and narratives with social concern. Contemporary paradigms explore new directions to reconnect and be the definition of society in different modes of art. In this study, art and artists will be explored who have contributed to society in profound ways. Their installations will determine the social metaphors evoked and how they unveil the provocative binary of community, how their art has broken stereotypes and became the benefactors of community. This study will also reveal the significance of art in society, in the nation and in the market with visual inputs. In the contemporary domain, art can be shown as personal experiences or with universal themes such as war and migration, which is unfortunately still exists with people suffering irreplaceable scars. This study highlights leading women artists who are critically involved with their societies.
Diallyl trisulfide induces pro-apoptotic autophagy via the AMPK/SIRT1 signalling pathway in human hepatocellular carcinoma HepG2 cell line
Authors: Sun Shuoshuo , Liu Xiyu , Wei Xiao , Zhang Shaohong , Wang Weimin
Published: May 2023

Background: Liver cancer is associated with a high mortality rate worldwide. Hepatocellular carcinoma (HCC) constitutes a large proportion of primary liver cancers, and most of its alterations currently remain untreatable. Diallyl trisulfide (DATS), the main chemical constituent of allicin, affects tumour development by regulating cell apoptosis. Allicin-induced autophagy could contribute to apoptosis in HepG2 cells. We rigorously examined the autophagy-related mechanism of allicin-induced apoptosis in HepG2 cells. We treated HepG2 cells with DATS to explore the effect of DATS on pro-apoptotic autophagy in HepG2 cell lines and examine its specific molecular mechanism.

Methods: HepG2 cells were treated with various concentrations of DATS for 24 and 48 h. Subsequently, cell viability was measured using the cell counting kit-8 (CCK-8) assay and cell clone formation assay. The HepG2 cell apoptosis was measured using Hoechst 33258 staining and western blotting. Autophagy and the AMP-activated protein kinase (AMPK)/NAD-dependent deacetylase sirtuin-1 (SIRT1) signalling pathway were detected using western blotting.

Results: Our results indicated that DATS inhibited HepG2 cell growth. Moreover, the ability of DATS to promote apoptosis in HepG2 cells increased with increasing concentration. We verified the phenomenon of DATS-induced autophagy in HepG2 cells and demonstrated that DATS treatment upregulated the protein expression of LC3-II/I. By measuring the expression of potential autophagy stimulators, we documented that DATS could induce pro-apoptotic autophagy by activating the AMPK/SIRT1 signalling pathway.

Conclusion: DATS induced pro-apoptotic autophagy via the AMPK/SIRT1 signalling pathway in the human HCC HepG2 cell line. Our findings further implicate allicin as a potential therapeutic agent against liver tumours in clinical settings, providing a basis for combining allicin with an autophagy agonist for treating liver cancer.

The treated seeds were kept in moisture vapour pervious (cloth bag) and moisture vapour proof (700 gauge polythene bag) containers under ambient conditions for six months. With regard to seed quality attributes, significant differences were observed among seed treatments, storage containers and periods of storage. The seed quality evaluations at monthly intervals revealed that increasing trend in germination per cent, speed of germination, drymatter production, vigour index, electrical conductivity, moisture content and free fatty acid content were observed with the increase in storage period. Among the seed pelleting treatments, seeds pelleted with arappu leaf powder showed superiority over other treatments and control. Arappu pelleting treatment proved to be the best in maintaining vigour and viability of seed throughout the storage period of six months. Reduction of oil content in arappu treatment was less compared to other treatments and control. Pelleting with neem leaf powder showed poor performance. With regard to containers, 700 gauge polyethylene bag proved to be superior to cloth bag in maintaining germination, vigour and drymatter production. With the advance in the storage period, an increase in electrical conductivity, moisture and free fatty acid content of seed were observed.

Studies were carried out to assess the influence of weather parameters on the incidence of coffee berry borer, Hypothenemus hampei (F.) at three locations in lower Pulney hills of Tamil Nadu during 2004 - 05 and 2005 - 06. In all the three locations, the infestation was higher (19.71%) in robusta than in arabica coffee varieties. In both the varieties, the peak period of infestation occurred between November and December. Correlation between weather parameters and infestation of coffee berry borer revealed a negative association with maximum temperature and rainfall at all the three locations while a positive relationship with maximum and minimum relative humidity with reference to the infestation of berry borer. Irrespective of the locations surveyed the population build-up of coffee berry borer in left over berries had served as a main source of inoculum for their carryover to the next season. The mean number of borer adults emerged from gleaning was high (21.72) due to rain followed by 12.93 and 12.52 recorded in mere water spray and surface temperature, respectively.

Published: May 2023

An automatic surge irrigation system was fabricated and field tested to establish its efficacy under on-farm irrigation water management. The system was based on sequential operation. A time switch and an electromagnetic valve were the main components of the system. Field evaluation of this automatic surge irrigation system was carried out at Tamil Nadu Agricultural University, Coimbatore. Efficacy of automatic surge irrigation system over continuous flow system was experimentally evaluated in paired row furrows of 120 cm width in terms of waterfront advance times, infiltration patterns and soil moisture distribution efficiencies. Automatic surge flow was found to make the soil reach its basic infiltration rate much quicker, 35 to 50 percent of the time elapsed in continuous flow. This facilitates quicker waterfront advance resulting in more uniform storage and distribution of soil moisture from head to tail end of the field with minimum losses. Surge flow in 160 m long furrow was found to cause 48 percent reduction in the advance time as taken by the continuous flow and it took 59 percent of the net duration of irrigation to advance to the tail end. Though it is better than continuous flow in saving advance time the greater proportion for its advance time (59%) over the net irrigation time limits its application up to 120 m long furrows only. The longitudinal distribution of soil moisture after irrigation was found to be more uniform in furrows under automatic surge flow compared to continuous flow.

Dried arecanut (Areca catechu) is widely used as a component of the betel leaf chewed in India. The arecanut processing industries are currently drying the nuts after boiling of nuts by open sun drying for 8 to 10 days. The moisture content of processed arecanut is reduced from 40 to 11 % during drying operation for safe storage and to maintain food quality. For the drying process, a solar cum biomass based dryer with a capacity of 1 tonne per batch was developed to meet the thermal energy requirement. The dryer consists of PAU (Punjab Agricultural University) packed bed model solar collector of 20m2 area, biomass burner, heat exchanger, air blower and hot air duct. The results showed the system to have a capacity to increase air temperature by 15-20°C above. In addition, the organoleptic evaluation reveals that the arecanut being dried in the solar cum biomass dryer system was completely protected from rain, insects and dust. The dried arecanut was of higher quality in terms of flavor and colour compared to open sun dried product, besides saving of time.

Yield is the result of interaction between genotype and environment (G x E). It is closely associated with many growth and yield attributing characters. This relation may be positive or negative. It can be studied through correlation. In other words, the systematic inter-relationship between the variables can be understood by using correlation (Rangaswamy, 2005). Path coefficient analysis helps in separating the direct effect from indirect effect by partitioning the correlation coefficients. The information on correlation and path coefficient studies in regular agronomic experiments is meagre. Hence, the present investigation was undertaken to assess and measure the magnitude of relationship between grain yield of rice and other characters.

In rainfed cultivation, sorghum seeds are sown as premonsoon sowing, where in seeds must emerge out with the available moisture. Thus, to impart drought resistance to young plants seed hardening is given as presowing management technique which is a boon for dryland agriculture. Short term hydration of seed before planting, greatly benefits stand establishment, but use of chemicals in water like potassium or sodium phosphate will give additional advantage. Apart from seed hardening, pelleting with nutrients or leaf powders is recommended, for absorbing and regulating the soil moisture and to enhance the better seed soil relationship under stress conditions. With this in view, the present investigation was carried out to study the effect of hardening combined with DAP pelleting on productivity and the storability of hardened seeds of sorghum var. APK 1 under rainfed cultivation.

Seed size is one of the characters associated with seed quality. The influence of seed size on seedling vigour and crop performance has been established in different crops like soybean, maize, gram and ashgourd. Variability in fruit size and shape is seen in pumpkin, even under good management. A significant correlation was reported between the fruit weight and number of good seeds in cucumber. Large sized fruits selected at the field level ensured recovery of large size seeds, which produce healthy, vigorous seedlings that was reported in ashgourd. Such information is lacking in pumpkin. The present studies were undertaken to trace out the influence of fruit grading on seed quality in pumpkin cv. CO2

Generally in crop cultivation sowing is taken up with two to three seeds per hill and are thinned at later stage to one to two seedlings per hill. For seed production maintenance of one seedling per hill is highly recommended as minimum number of seedlings to enable the plant to grow profusely which ultimately increases the yield and quality characters of the resultant seed. Moreover, studies on number of seedlings per hill will be appropriate as entering into field after cultivation will be much difficult in spiny types of safflower. Standardization of such management technique would be useful for increased seed yield with better seed quality characters. Hence, studies were made with spiny type safflower cv. K 1 released from TNAU, Coimbatore, Tamil Nadu, India.

Maize is the fourth major grain crop grown in Tamil Nadu for poultry feed. Intensive cropping coupled with introduction of high yielding varieties have extensively exhausted the soil fertility with respect to macro and micronutrients. Further, use of S free fertilizers has caused depletion of S in soils. Zinc deficiency in Indian soils and responses to its application on various crops has been reported earlier (Singh, 1999). Next to Zn, B deficiency is wide spread in many soils and in calcareous and coarse textured soils in particular leading to low crop yields. The research carried out on the use of organics. The treatments involving Zn application registered higher DTPA Zn and the treatment of 2.5 kg Zn + 1.5 kg B ha-1 enriched FYM (T5) accounted for higher value of 1.03 mg kg-1 followed by 5.0 kg Zn ha-1) enriched with FYM (T4) with 1.01 mg kg-1.

Reliability in engineering is defined as the probability that a device will satisfactorily perform its specified function for a specified period of time under a given set of operating conditions. Reliability is thus a mathematical expression of the likelihood of satisfactory operation. Though the repair cost of tractor is high the subsequent loss due to delay in carrying out the repair is potentially much greater than the cost of repair. Under such condition any stoppage of tractor can cause sizeable loss, due to delay in carrying out the timeliness of farm operations during the peak seasons apart from inefficient labour utilization. Hence the reliability of tractor has become more important, while the breakdown of an individual subsystem of a tractor is an annoyance

Post harvest losses are considerably high in India. Dehydration technology plays a vital role in the preservation of fruits and vegetables, by converting them to a stable form that can be stored throughout the year. Tomato is an important seasonal vegetable widely grown in India. It contains 0.9% protein, 48% calcium and 3.6% carbohydrates and offers 20 Kilocalories of energy. Biochemical analysis showed that, the total ash content was found to increase as the percentage of dextrose levels increases. Treatment with 1200 ppm SMBS and 1% calcium chloride had an increased crude fat level, that caused a higher level of discolouration in the dehydrated sample. Reducing sugar levels were the highest in the best-treated sample.
O que faz a Música ser Especial e o seu Ensino Especializado

A música ocupa o lugar intermédio perfeito de ser de todos e ao mesmo tempo de cada um de nós. Neste sentido, quando perguntámos o que é música a um habitante do norte do Alaska, a um da África Austral, e a um outro da Indonésia, todos saberão dar uma resposta, mas cada um poderá dar como exemplos expressões musicais não reconhecidas pelos outros. Deste mesmo modo, as escolas de música de cada uma dessas regiões ensinam um ‘tipo de música’, que ao ser aprendida não garante capacidades de interpretar as ‘outras músicas’. Na era da híper-globalização, e sendo também um dos objetivos maiores da educação o formar e educar para o futuro, é então premente o constante (re)pensar do que fazemos no presente, tentando antecipar o futuro. Considerando que a prática musical tem por um lado funções societais práticas (e.g. para dança; som ambiente), mas também é (ou poderá ser) arte, neste artigo ir-se-á refletir sobre contínuos paradigmas do seu ensino: o que realmente ensinamos; o porquê; e para quem.

O presente estudo indaga o recurso a diferentes géneros musicais nas aulas de Coro e o impacto na motivação dos alunos. O interesse pelo tema surgiu, principalmente, da experiência enquanto discente, já que, frequentemente, o repertório escolhido comprometia a motivação, assim como a não oportunidade de participação ou a rejeição de sugestões dos alunos. Surgiu, então, a questão de investigação: a introdução dos géneros musicais Pop e Musical poderá ser um fator de motivação nos alunos, nas aulas de Coro? Diversos autores realçam que a escolha do repertório tem influência na motivação dos coralistas, auxiliando a formação de músicos cultos e conhecedores do património coral. A aplicação de questionários pré e pós intervenção, incidindo nos fatores motivacionais, permitiu determinar que os alunos: gostaram das aulas lecionadas que utilizaram o Pop e o Musical; gostaram mais de cantar uma canção proposta por eles; estiveram mais motivados quando se utilizaram os géneros em estudo. Concluiu-se que, a utilização dos géneros Pop e Musical e a participação dos alunos na escolha do repertório geraram mais motivação, com impacto positivo aparente na performance coral. Os resultados obtidos permitem deduzir que a inclusão de géneros não eruditos nas aulas de Coro pode ser benéfica e motivadora.

O presente estudo resultou da intervenção pedagógica no âmbito do Estágio Profissional do Mestrado em Ensino de Música da Universidade do Minho e descreve um conjunto de atividades musicais baseadas no pensamento jazzístico aplicadas ao ensino da Formação Musical e História da Música. Neste trabalho, contextualizamos o recurso à improvisação musical nos diferentes períodos da História da Música Ocidental e referimos o seu declínio. Mencionamos a sua revitalização na construção da linguagem jazz e analisamos os processos que permitiram a sua consolidação ao longo do século XX. Desta análise, abordamos o valor educativo deste tipo de ensino, nomeadamente a valorização de técnicas de imitação e escuta atenta. Associamos a estas aprendizagens os principais pedagogos, designadamente os que defendem as teorias de ensino construtivistas, e procuramos demostrar os benefícios da construção de conhecimento alcançado através de mecanismos de pensamento semelhantes aos de um improvisador de jazz.
Performance Musical: Melhor com Recurso à Partitura?
Authors: (danieljflemos@gmail.com) Daniel Joaquim Ferreira Lemos

O presente projeto resultou do Estágio Pedagógico desenvolvido no âmbito do Mestrado em Ensino de Música da Universidade do Minho e teve como finalidade dar uma resposta acerca da importância do uso da partitura na performance musical. A escolha desta temática deveu-se ao facto de sempre me interrogar acerca do que seria melhor na performance musical: ter a partitura em palco ou executar a performance de memória, sem o recurso à partitura. Do ponto de vista do público, e tendo em conta o aspeto cénico, pretendo perceber o que este prefere na performance de um músico em palco. Será para o público mais apelativo a execução instrumental com ou sem partitura? Será que o público consegue perceber se há diferenças na performance musical com o recurso à partitura ou sem ela? Os dados obtidos, aplicados aos diferentes intervenientes, através de audições públicas, questionários a músicos profissionais e ao público em geral, revelam que a performance musical sem o recurso à partitura obteve uma maior aceitação. Contudo, os resultados obtidos entre executar a performance de memória, sem o recurso à partitura, e executar com o recurso à partitura não são muito acentuados. Existe a preferência em tocar de memória, sem o auxílio da partitura, no entanto as diferenças entre as duas opções não são muito significativas.
