Published: April 2023

Runoff is a valuable water resource during seasonal freezing and thawing period in arid and semi-arid areas, and is of great significance to ecological restoration in coal mining subsidence areas. Through automatic in-situ monitoring of the dynamic changes of soil moisture and temperature inside and outside the coal mining subsidence area of different site types, the spatio-temporal heterogeneity of soil moisture and temperature during freezing and thawing period was analyzed, so that to explore the characteristics of soil moisture and temperature changes in the loess-aeolian mining subsidence area during the seasonal freeze-thaw process in the area connected Shanxi and Inner Mongolia. The results show that: (1) The study area belongs to seasonal frozen soil, and the freezing time is generally from December to March of the following year, and there is a certain hysteresis of soil freezing and thawing to atmospheric temperature. The influence of temperature on soil temperature is mainly concentrated in 0 ~ 40cm topsoil, and such effect intensity is negatively correlated with soil depth. (2) Different types of coal mining subsidence areas have different characteristics in soil Hydro-thermal coupling. The thawing time of the four sites from early to late: outside the loess subsidence area > within the loess subsidence area > outside the aeolian sand subsidence area > within the aeolian sand subsidence area. Among them, soil thawing in the sand and loess coal mining subsidence area lags behind the outside area. 2d. (3) The variation coefficient of soil moisture in the aeolian sand subsidence area during freezing and thawing period ranges from 0.1568 to 0.6271, which is larger than that in the loess subsidence area. Except for the 20-30cm soil layer in the loess coal mining subsidence area, the water content of other soil layers is higher than the outside; while the 0-20cm, surface layer, in the wind-sand coal mining subsidence area has higher soil water content than the 20-60cm layer outside the subsidence area. The water content is lower than outside the subsidence zone. (4) During the freeze-thaw process, the soil temperature and moisture at different depths showed a polynomial function relationship, and the correlation in the surface layer was stronger than that in the deep one. The research results can provide an important reference for understanding the relationship between soil freezing-thawing and hydrological processes in coal mining subsidence areas.

Published: April 2023

Purpose: Multifocal/multicentric glioblastomas (mGBM) account for up to 20% of all newly diagnosed glioblastomas. The present study investigates the impact of cytoreductive surgery on survival and functional outcomes in patients with mGBM.Methods: We retrospectively reviewed clinical and imaging data of 71 patients with newly diagnosed primary (IDH1 wildtype) mGBM who underwent operative treatment in 2015–2020 at the authors’ institution. Multicentric/multifocal growth was defined by the presence of ≥ 2 contrast enhancing lesions ≥ 1 cm apart from each other.Results: 36 (50.7%) patients had a resection and 35 (49.3%) a biopsy procedure. MGMT status, age, preoperative KPI and NANO scores as well as the postoperative KPI and NANO scores did not differ significantly between resected and biopsied cases. Median overall survival was 6.4 months and varied significantly with the extent of resection (GTR: 13.6, STR: 6.4, biopsy: 3.4 months; P = 0.043). 21 (58.3%) of resected vs. only 12 (34.3%) of biopsied cases had radiochemotherapy (p = 0.022). Multivariate analysis revealed chemo- and radiotherapy and also (albeit with smaller hazard ratios) extent of resection (resection vs. biopsy) and multicentric growth as independent predictors of patient survival. Involvement of eleoquent brain regions, as well as neurodeficit rates and functional outcomes did not vary significantly between the biopsy and the resection cohorts.Conclusion: Resective surgery in mGBM is associated with better survival. This benefit seems to relate prominently to an increased number of patients being able to tolerate effective adjuvant therapies after tumor resections. In addition, cytoreductive surgery may have a survival impact per se.

Published: April 2023

Telemedicine has become increasingly important in healthcare, especially with the COVID-19 pandemic. Alodokter, one of the pioneers of health applications providing telemedicine services in Indonesia since 2014, has gained significant attention. Younger generations–Millennials and Gen Z–are more fluent in using technology. However, previous study shows that older generations (Gen X) is more satisfied in using telemedicine compared to younger generations. This study aims to identify the factors influencing user satisfaction and behavioral intention towards Alodokter's telemedicine service application usage among Millennials and Gen-Z in Indonesia. A survey was conducted on 160 respondents using a purposive sampling technique. The data was analyzed using the PLS-SEM based method with the SmartPLS MacOS application version 3.2.9. The study focused on examining the relationships between the variables of behavioral intention, customer satisfaction, and factors including performance expectancy, effort expectancy, price value, and social influence. The study findings indicate that customer satisfaction positively affects behavioral intention. Performance expectancy, effort expectancy, price value, and social influence positively impact customer satisfaction. Price value was shown to have the most positive influence on behavioral intention. The study provides insights into the factors influencing user satisfaction and behavioral intention towards telemedicine service application usage among younger generations in Indonesia. The results can be used to improve telemedicine services and enhance the experience of users, particularly Millennials and Gen-Z.

Published: April 2023

A low-roughness ultra-thin copper foil was prepared by pulsed electrodeposition on titanium substrate. The influence of sodium 3,3'-dithiodipropane sulfonate (SPS), hydroxyethyl cellulose (HEC), gelatin and collagen additives on the microstructure, mechanical properties and electrochemical behavior of electrolytic copper foil was explored. Furthermore, the reaction mechanism of SPS and collagen additives on electrodeposited copper was discussed. The results showed that at 0.08 g/L collagen concentration, the lowest thickness, the highest microhardness and the optimal surface roughness were achieved to be 5.12 µm, 279.63 HV0.05 and 1.885 µm, respectively. X-ray diffraction results confirmed that electrolytic copper foils prepared by SPS was introduced into the blank solution had a preferred orientation of (220) texture, which benefitted from the synergistic effect of copper ions and additives. The intermediates formed by the additive and Cu+ occupied the active sites on the cathode surface that increased nucleation sites for deposition. Besides, the formed complexes can act as a barrier to narrow ion deposition channels and inhibit the growth of Cu ions.
Untangling the role of optimism, pessimism and coping influences on student mood, motivation and satisfaction.
Authors: Gibbons Chris
Published: April 2023

The aims explored the associations between stress and eustress ratings and influences on coping (control, support and personality), on mood, course satisfaction and learning motivation. Undergraduate students, (N = 175), were surveyed on student stressors, personality, support and control against mood, course satisfaction and motivation. Defensive pessimism, context control and agreeableness lowered anxiety, while neuroticism, extraversion and hassle ratings of tutor support, increased it. Control and neuroticism mediated between the hassle ratings accorded to support from family and friends and anxiety. Optimism and defensive pessimism lowered depression scores. Those in the upper quartile on Defensive pessimism, compared to those in the upper quartile on optimism, scored lower on anxiety, higher on learning motivation and course satisfaction and this is despite the optimism group being higher in self-efficacy, control and conscientiousness. Both groups scored higher than the cohort average on GPA, with the upper quartile in optimism, highest. The results suggest context control, defensive pessimism and optimism all offer effective coping, with individual difference an important caveat – for those capable and high in anxiety, defensive pessimism was effective. An optimistic outlook is unlikely to be helpful. It may even have negatives, while optimistic thinking strategies together with defensive pessimism are likely to boost motivation, satisfaction and mood.

Published: April 2023

About 40 years ago, plastic packaging was almost never used in Ukraine. Food products were sold in glass bottles, iron cans or in paper wrappers, which were decomposed in the environment or handed over to recycling centres. However, in recent years, the situation has fundamentally changed all over the world. Almost all products have several layers of packaging made of synthetic polymer materials. It has led to the significant growth of landfills and, therefore, to the emergence of a new problem – their proper maintenance. Landfills are areas of land where household, construction and other wastes are stored without control. To reduce the volume of waste, landfills are often set on fire. This approach is unacceptable, as landfills are a serious source of soil, air and water pollutions. Arbitrarily created waste disposal points are not equipped appropriately, the products of waste decay fall into the soil and groundwater, which is the source of water supply for a large number of the national population. The decay temperature in some cases is so high that it often leads to their ignition, and large amounts of harmful substances are released into the air. In this article, the authors conducted a study of the terminological orientation of scientific publications in the context of identifying the impact on human health of the waste conversion into energy compared to the impact of the landfill operation. Bibliographic information about scientific publications in peer-reviewed publications were preliminarily acquired from the Scopus database. The obtained results showed that researchers are investigating the impact of landfills on the population health, mainly focusing on such concepts as “health”, “landfills”, “waste incineration”. The authors analysed the dynamics of scientific interest levels in this topic and determined that the highest rate would be in 2022. It confirms the growing relevance of the researched problem in the modern world. All authors’ considerations are illustrated by corresponding diagrams and tables.

The genus Capsicum has been distinguished by its lack of compatible rootstocks with commercial cultivars to successfully protect against Phytophthora capsici. Criollo de Morelos 334 (CM334) has been used worldwide in crosses and as a rootstock to protect against P. capsici. However, novel sources of resistance to this pathogen, such as ‘Pasilla 18M’ have not yet been explored as rootstocks. A good rootstock should be highly compatible with the scion and also maintain the quality and/or provide a benefit to the grafted cultivar. Our objectives were 1) to evaluate grafting survival using ‘Pasilla 18M’ and CM334 as rootstocks of two susceptible commercial cultivars: Sweet Pepper California Wonder (CW) and Serrano Coloso; and 2) to evaluate the efficiency of ‘Pasilla 18M’ as rootstock against P. capsici using CM334 as a resistant control. Grafting survival was analyzed over 58 days after grafting in sets of 60 plants per varietal combination. Disease severity and incidence were recorded during 24 days after inoculation with P. capsici (DAI). Incidence was also evaluated at 54 and 84 DAI. A severity scale from 0 (healthy plant) to 4 (dead plant) was applied to evaluate root rot per plant. Incidence was recorded as the percent of diseased plants (severity >0). Grafting survival of intervarietal grafts was 87% to 94%, similar to ungrafted cultivars, and exceeding autograft survival. Ungrafted and autografted Sweet Pepper and Serrano showed root rot severities 2.3 to 3.3, with 89% to 100% incidence. In contrast, intervarietal grafts remained almost free of infection (severity 0.14; incidence 0% to 4%). CM334 and ‘Pasilla 18M’ rootstocks are highly compatible with ‘Serrano Coloso’ and ‘Sweet Pepper CW’. ‘Pasilla 18M’ confers the same level of protection against P. capsici as CM334.

Authors: Kovaleva Yu. S. , Vedler A. A.
Published: April 2023

Introduction. The systemic psoriatic process affects not only the skin, but also other organ systems, including the cardiovascular system. Immunopathological inflammation that occurs in the skin and articular tissues is a central link in the pathology of the cardiovascular system in psoriasis.

Objective. Identify diseases of the cardiovascular system and factors of their development in patients with psoriasis and to assess their severity depending on the severity of dermatosis.

Materials and methods. The study included 406 patients with psoriasis aged 18 to 74 years, who were divided into three subgroups depending on the severity of the course. Assessment of the state of the cardiovascular system was carried out using the following methods: uestionnaire, clinical, physical, laboratory and statistical. The comparison group consisted of 200 people.

Results. In 53.9% of patients, psoriasis occurred against the background of cardiovascular comorbidity. More than 90% of patients with moderate to severe psoriasis have more than three risk factors for CCC diseases. Patients are more susceptible to the development of hypertension, hypercholesterolemia, obesity, abdominal obesity, stress and smoking. The higher the cardiovascular risk, the more severe psoriasis is.

Conclusions. The presence of unmodified and modifiable risk factors for the development of cardiovascular diseases is aggravating for the course of psoriasis, which means that the risk of undesirable fatal events is higher. Patients with psoriasis need additional preventive measures aimed at preventing the development of cardiovascular pathology.

Seguimiento de las poblaciones de tritones torrentícolas Calotriton asper y Calotriton arnoldi. Marco conceptual y casos prácticos
Authors: Montori Albert
Published: April 2023

Existen distintas metodologías para conocer tendencias poblacionales, detectar declives y disponer de los elementos de diagnosis necesarios para la gestión de poblaciones y especies. Hasta hace poco muchos seguimientos sólo valoraban el estado de las poblaciones comparando distribuciones. Sin embargo, es necesario realizar seguimientos a largo plazo teniendo en cuenta que una gran parte de las especies de anfibios tienen una estructura metapoblacional. Estos seguimientos se basan en el censo de ejemplares en los puntos de reproducción por detección de cantos, conteo visual o captura de larvas. Este tipo de metodología es muy útil para especies que habitan fundamentalmente medios lénticos. La dificultad de localizar los ejemplares adultos y sus larvas en medios acuáticos reófilos obliga a realizar seguimientos muy específicos. En este estudio se presentan la metodología empleada en el seguimiento durante 21 años de una población de Calotriton asper (Dugès, 1852) en el Parc Natural del Cadí-Moixeró (Barcelona, Girona y Lleida) y la usada para la caracterización de todas las poblaciones del Parque, con el objetivo de determinar las poblaciones clave para realizar seguimientos a largo plazo con costes asumibles. Se describen las distintas tipologías de seguimiento utilizadas en las poblaciones de Calotriton arnoldi Carranza & Amat, 2005 dentro del Proyecto Life Tritó del Montseny, y finalmente se exponen los criterios y la metodología de seguimiento utilizados en el proceso de creación de nuevas poblaciones de esta especie catalogada como en peligro crítico.
La justice constitutionnelle en France, du rejet à l’adoption
Authors: Martial Mathieu
Published: April 2023

L’histoire constitutionnelle française a longtemps été dominée par une tradition d’hostilité au gouvernement des juges. En effet, la Révolution française consacre une conception de la loi qui place les juges dans un rapport de subordination et de dépendance à l’égard de la législation. Elle condamne ainsi les prétentions des cours supérieures de justice, qui ont tenté de soumettre la législation royale au respect de principes constitutionnels. Des Lumières au Second Empire, les tentatives visant à imposer la suprématie des normes constitutionnelles se heurtent à la souveraineté de la loi parlementaire, qui connaît son apogée sous la Troisième République. Au cours de la seconde moitié du XXe siècle, cette tradition légicentriste s’érode progressivement, face au développement de la justice constitutionnelle dans les pays d’Europe occidentale. Pourtant, au lendemain de la Seconde guerre mondiale, les partisans du contrôle de constitutionnalité sont loin de tous considérer qu’il faut confier cette tâche à une juridiction. L’hostilité au gouvernement des juges conduit ainsi à l’instauration du contrôle de constitutionnalité sans justice constitutionnelle. L’émergence progressive de la justice constitutionnelle sous la Cinquième République procède d’une rupture avec l’esprit de la constitution de 1958. Initiée par le Conseil constitutionnel, cette évolution a ensuite été confirmée par la révision de la constitution, consacrant l’adoption laborieuse de la justice constitutionnelle par les institutions françaises.

Authors: Thornton Christopher , Lanyi Kate , Wilkins Georgina , Potter Rhiannon , Hunter Emily , Kolehmainen Niina , Pearson Fiona
Published: April 2023

BACKGROUND

Health technology innovation is increasingly supported by a bottom-up approach to priority setting, aiming to better reflect the concerns of its intended beneficiaries. Web-based forums provide parents with an outlet to share concerns, advice, and information related to parenting and the health and well-being of their children. They provide a rich source of data on parenting concerns and priorities that could inform future child health research and innovation.

OBJECTIVE

The aim of the study is to identify common concerns expressed on 2 major web-based forums and cluster these to identify potential family health concern topics as indicative priority areas for future research and innovation.

METHODS

We text-mined the r/Parenting subreddit (69,846 posts) and the parenting section of Mumsnet (99,848 posts) to create a large corpus of posts. A generative statistical model (latent Dirichlet allocation) was used to identify the most discussed topics in the corpus, and content analysis was applied to identify the parenting concerns found in a subset of posts.

RESULTS

A model with 25 topics produced the highest coherence and a wide range of meaningful parenting concern topics. The most frequently expressed parenting concerns are related to their child’s sleep, self-care, eating (and food), behavior, childcare context, and the parental context including parental conflict. Topics directly associated with infants, such as potty training and bottle feeding, were more common on Mumsnet, while parental context and screen time were more common on r/Parenting.

CONCLUSIONS

Latent Dirichlet allocation topic modeling can be applied to gain a rapid, yet meaningful overview of parent concerns expressed on a large and diverse set of social media posts and used to complement traditional insight gathering methods. Parents framed their concerns in terms of children’s everyday health concerns, generating topics that overlap significantly with established family health concern topics. We provide evidence of the range of family health concerns found at these sources and hope this can be used to generate material for use alongside traditional insight gathering methods.

Published: April 2023

BACKGROUND

Rheumatoid arthritis (RA) is distinguished by the presence of modified bone microarchitecture, also known as 'texture,' in the periarticular regions. The radiographic detection of such alterations in RA can be challenging.

OBJECTIVE

To train and to validate a deep learning model to quantitatively produce periarticular texture features di-rectly from radiography and predict the diagnosis of early RA without human reading. Two kinds of deep learning models were compared for diagnostic performance.

METHODS

Anterior-posterior bilateral hands radiographs of 891 early RA (within one year of initial diagno-sis) and 1237 non-RA patients were split into a training set (64%), a validation set (16%), and a test set (20%). The second, third, and fourth distal metacarpal areas were segmented for the Deep Texture Encod-ing Network (Deep-TEN; texture-based) and residual network-50 (ResNet-50; texture and structure-based) models to predict the probability of RA.

RESULTS

The area under the curve of the receiver operating characteristics curve for RA was 0.69 for the Deep-TEN model and 0.73 for the ResNet-50 model. The positive predictive values of a high texture score to classify RA using the Deep-TEN and ResNet-50 models were 0.64 and 0.67, respectively. High mean tex-ture scores were associated with age- and sex-adjusted odds ratios (ORs) with 95% confidence interval (CI) for RA of 3.42 (2.59–4.50) and 4.30 (3.26–5.69) using the Deep-TEN and ResNet-50 models, respectively. The moderate and high RA risk groups determined by the Deep-TEN model were associated with adjusted ORs (95% CIs) of 2.48 (1.78–3.47) and 4.39 (3.11–6.20) for RA, respectively, and those using the ResNet-50 model were 2.17 (1.55–3.04) and 6.91 (4.83–9.90), respectively.

CONCLUSIONS

Fully automated quantitative assessment for periarticular texture by deep learning models can help in the classification of early RA.
Analysis on the Protection of Short Video Copyright and Countermeasures for Short Video Copyright Protection
Authors: Liao Zhiya , Fu Xiaoling , Yang Qianhui
Published: April 2023

Short video is born with the development and operation of the Internet environment and has become one of the most popular entertainment consumer products. However, while the short video industry is booming, it also faces the problem of copyright infringement. The reason is that the creation, secondary creation and dissemination of short videos are simple and the cost of infringement is low, so the frequent infringement cases hinder the development of short video market which discourage the enthusiasm of video creators. Alleviating copyright infringement will help copyright protection agencies and relevant laws and regulations improve. Therefore, this paper studies the current short video industry, the current typical infringement phenomenon was described. To be specific, it describes in detail the problems existing in the current governance of copyright in the field of short video. The definition and ownership of short video copyright is not clear, the short video content supervision system is not perfect, and the responsibilities of short video platforms are still to be solved. In view of the outstanding problems, the paper proposed the countermeasures to complete the definition and attribution of short video, establish a sound supervision system, and improve the responsibility of short video platform.

Corn stover is a low-quality forage rich in lignocellulosic material. However, it is also a palatable and low-cost feedstuff for cattle. In this study, we hypothesized that feeding exclusively a corn stover-based diet (CSD), compared with one based on corn silage-oat hay, increases the abundance of the bacterial families and genera involved in cellulose and hemicellulose metabolism. For that purpose, we collected filtered ruminal fluid from six dry Holstein cows during two periods: Period 1, cows consumed a control diet based on corn silage and oat hay (CD), and in the Period 2, cows were fed CSD for 45 days. Ruminal fluid was collected through esophageal tubing. Ruminal microorganisms were identified by sequencing the 16S rRNA gene using the Illumina MiSeq platform. Compared with CD, feeding CSD for 45 days increased bacterial families and genera associated with higher neutral detergent fiber content and esterase and hemicellulolytic activities, such as Rikenellaceae, Prevotella, and Pseudobutyrivibrio. These results indicate that the liquid fraction of ruminal digesta contains a large number of microorganisms that help degrade lignocellulosic complexes, especially when diets with low-quality forages such as CSD are fed.

Os filtros lentos são de fácil construção, operação e manutenção, tornando-se adequados para o tratamento de água também em pequenas comunidades. Apesar do meio filtrante comumente empregado ser de areia, estudos sugerem a substituição integral ou parcial da mesma por materiais não convencionais, desde que mantenha a eficiência no tratamento de água. Assim, o objetivo desse trabalho foi verificar a eficiência de filtros lentos utilizando os materiais sustentáveis fibras de coco e resíduo cerâmico misturados à areia como meio filtrante. Para isso, montou-se em escala laboratorial, três filtros lentos com diferentes meios filtrantes, são eles: areia misturada com resíduo cerâmico (Filtro 1), areia misturada com fibras de coco (Filtro 2) e filtro convencional de areia (Filtro 3). Os filtros operaram com fluxo descendente à taxa de filtração de 3 m³/m².dia (± 10%) de forma contínua, alimentados com água subterrânea com adição de lodo de ETA. A água bruta e a água tratada pelos filtros foram analisadas quanto aos padrões de qualidade da legislação vigente. Os filtros também foram comparados entre si em termos de eficiência, para verificar qual deles apresentou melhor desempenho no tratamento. Embora os três modelos de filtros analisados tiveram desempenhos semelhantes e trouxeram benefícios ao tratamento água contaminada com coliformes totais e termotolerantes, o Filtro 1 apresentou maior eficiência na remoção dos parâmetros físico-químicos turbidez e cor aparente, o Filtro 2 apresentou maior eficiência apenas na remoção de coliformes termotolerantes e o Filtro 3 na remoção de sólidos dissolvidos totais. Portanto, nos casos em que houver disponibilidade de resíduo cerâmico ou fibra de coco, é indiciado que estes materiais sejam misturados à areia para melhor desempenho dos meios filtrantes.

O descarte e tratamento dos resíduos do coco em aterros de resíduos sólidos urbanos é um problema recorrente em locais onde seu consumo é bastante elevado. As propriedades de biodegradação deste material, somadas ao seu grande volume, contribuem para a redução da vida útil dos aterros sanitários. Como forma de buscar alternativas para o aproveitamento desse tipo de resíduo no contexto geotécnico não saturado, este trabalho propõe a inserção de fibras de coco para melhorar o comportamento geotécnico de solos argilosos compactados. Para tanto, foram analisadas misturas de solo com teor de fibras nas proporções de 0, 0.5, 1 e 2% em peso seco do solo em uma matriz argilosa compactada. A curva de retenção de água obtida experimentalmente e numericamente foram avaliadas. Os resultados mostraram que as misturas com 0.5 e 1% de fibras de coco apresentaram aumento na saturação e umidade volumétrica residual em relação ao solo natural, refletindo em maior nível de sucção para entrada de ar. Visando aplicações geotécnicas dessas misturas, houve uma melhora significativa nas características em aplicações onde o solo está sujeito a variações de ciclos de umedecimento e secagem, como nas camadas de cobertura de aterros e barreiras de contaminantes. A inserção dessas fibras tende a reduzir a produção de chorume e a emissão de gases através de camadas de cobertura de aterros ou barreiras de contaminantes por reter mais água do que o solo natural.

Published: April 2023

La generación de aguas residuales de la industria de nixtamalización del maíz (conocida como nejayote) en México asciende a 14.4 millones de m3/año. Este tipo de aguas residuales se distinguen por tener un pH alcalino >10, alto contenido de materia orgánica (33.2 gDQO/L en promedio) y una relación DBO5/DQO de 0.4, indicando que corresponde a un residuo con alta biodegradabilidad a través de su tratamiento por procesos biológicos anaerobios  con valorización energética. En este sentido, la fermentación oscura y la digestión anaerobia son procesos que ofrecen alternativas de aprovechamiento de esta agua residual, ya que además de estabilizar el residuo, genera subproductos de valor agregado como los ácidos grasos volátiles, metano, hidrógeno y digestato. Pocas investigaciones se han centrado en la producción de biogás a partir del nejayote, reportando rendimientos máximos de 282 mLCH4/gDQO y 49.3 NmLH2/gDQO, remociones entre el 50% hasta el 95% en términos de DQO. La valorización energética del agua residual de la nixtamalización tiene un potencial energético que puede alcanzar hasta 20.4 kWh/m3 , la cual puede ser utilizada para cubrir el requerimiento energético de los equipos dinámicos y servicios auxiliares dentro del tratamiento y el remante puede ser utilizado dentro del giro industrial.

Abstract: Increase in human population increases the need for energy. Sustainable energy production is gaining importance day by day. At the same time rapid urbanization and industrialization combined with improper town planning has led to the destruction and death of nearby water bodies. Discharge of drainage water without aeration or any other treatment in Metropolitan Indian cities such as Delhi, Mumbai, Nashik and all others have to led to the blackening of water sources. Indian city drains handle sheer volumes of water every day. A new method of aerating water combined with power generation could go a long way in solving the problem of water treatment as well as power generation. Even under low head this much amount of water if efficiently utilized can generate sufficient power not only for the plant but also for the grid. By using the power of water in vortex flow under gravity, an attempt is made to make power from Indian drains. To generate electricity, water must be in motion. This is kinetic (moving) energy. When flowing water turns blades in a turbine, the form is changed to mechanical energy. The vortex is a form of kinetic energy storage by which water under motion is trapped in a dynamic way. This increased amount of kinetic energy that gets trapped inside a vortex boosts the power inside a vortex.
