The Performance of a Cross-flow Turbine as a Function of Flowrates and Guide Vane Angles
Authors: Adeyanju Anthony A. , Manohar K. 
Published: February 2022

This study looked at the effects of flow rates and guide vane angles on the performance of a cross flow turbine, which can be used to generate energy and hydraulic power with low head and low flow rates of water. A fluid dynamic analysis was performed on the cross-flow turbine with the aid of finite element techniques. The simulation was solved after validating the convergence of the provided model and its boundary conditions, with the outputs being the velocity profiles of the flow in the rotor and the pressure distribution on the rotor surface during its rotations. Experimental evaluation of the cross-flow turbine guide vane positions at a flow rate of 0.8, 0.6, and 0.5 m3/s was conducted, and it was discovered that a maximum turbine speed of 482 rpm and a generator speed of 1920 rpm were produced at the rotor shaft at a flow rate of 0.8 m3/s with a head of 25 m, and this data was validated by the results produced from the simulation.

Evaluation and Optimization of the Aerodynamic Noise Reduction of Vehicle Side View Mirrors: Experimental and Numerical Study
Authors: Gohari Mohammad , Norozi Rasoul , Hajizadeh Aghdam Abolfazl 
Published: February 2022

Automobile passengers are usually sensitive to the noises generated by the engine and vehicle body. One of the noise sources is the generated turbulent flow around the Vehicle Side View Mirror (VSVM) and around the A-pillar, producing fluctuating pressure. Unwanted noise is a result of fluctuating pressure around the car's body. Modification of the geometry of the vehicle body may affect the generated noise by turbulent flow. In this paper, the original side view mirror of a small sedan car named Tiba was aimed at geometry modification to decrease airborne noise. The mirror was assessed by CFD simulation and an outdoor test. Road tests were applied at three forward speeds (80, 100, and 120 km/h) to measure the sound level generated by the vehicle's side mirrors. Then, the geometry of VSVM was modified to diminish the sound pressure level of that based on decreasing turbulent flow and fluctuating pressure around the side mirror. Finally, the achieved geometry was evaluated using road tests, which showed a noise reduction of 8 to 12%. Road tests were done for the modified side car mirror. It shows that a modified mirror can reduce the sound level of airborne noise. By using this suggested modified side view mirror, the risk of annoying noise may be diminished and passenger comfort ability can be increased through driving.

Published: February 2022

Esse artigo visa compartilhar a experiência de discussão e realização da Assembleia sobre à Consulta Prévia, Livre e Informada junto ao povo Mura iniciada em dezembro de 2017 e finalizada em fevereiro de 2018. Originou-se dentro do processo que se conhece na Justiça Federal a partir da Ação Civil Pública impetrada pelo Ministério Público Federal (processo 19192-92.2016.4.01.3200) diante das denúncias do povo Mura contra atividades do empreendimento minerário para exploração de Silvinita, denominado Projeto Potássio Autazes/Amazonas, desenvolvido pela Empresa Potássio do Brasil após obter a licença prévia para fazer a prospecção do minério em Autazes sem realizar a Consulta Prévia, Livre e Informada como determina a Convenção 169 da Organização Internacional do Trabalho. O presente artigo pretende demonstrar a importância dessa discussão que antecedeu a elaboração do Protocolo de Consulta e Consentimento Prévio Livre e Informado, e que serviu para definir seus instrumentos e planejamento para os povos indígenas que ainda não construíram seus protocolos e principalmente a metodologia usada fundamentada na participação, autonomia e organização social, política e cultural destes. Como resultado, os Mura decidiram elaborar o Protocolo de Consulta antes da realizar a Consulta Prévia, definiram a metodologia para a elaboração do protocolo e ampliaram o número de Terras, comunidades e aldeias que seriam consultadas extrapolando os limites do município de Autazes não importando se estavam regularizadas ou não, pois todas são Terra Mura. Essa discussão prévia em assembleia, foi fundamental para que os Mura pudessem entender o que é Consulta Prévia como mais um instrumento de autonomia.

Marriage Rituals in Kol Tribe
Authors: Om Prakash  
Published: February 2022

Marriage is a sacred bond in which the bride and groom, taking their clan gods and fire as witnesses, commit to live together in each other's happiness and sorrow and in future life. In the Kol tribe, marriages are performed by many small rituals. Mandap Chhajan and Mayan Puja, Matrika Puja or Maati Mangal, the ritual of offering oil, Parchan, Janvasa, Dwarchar or Dwar Puja, Oli Bharai, Lava Parswai, Sindoordan, Mangal Phere, Kanyadaan, foot worship and Khobar. But in the present scenario, the role of the pandit in the marriage ceremony is visible from beginning to end. In the evening, men and women gather under the pavilion in the courtyard for entertainment, singing and singing with the help of musical instruments like dholak etc. Koldahka dances while playing. The groom resolves the bride to keep the promise. Always give advice to live happily with each other. After the marriage at the young age of the first bride, the gauna was performed in the third, fifth or seventh year when the bride became an adult. But now after becoming an adult, due to the marriage taking place, the cow is also done immediately. Remarriage among tribes is not difficult nor is it considered wrong. Yet divorce or divorce is not encouraged in any tribe.

Abstract in Hindi Language
विवाह एक पवित्र बंधन होता है जिसमें अपने कुल देवताओं तथा अग्नि को साक्षी मानकर वर तथा कन्या एक दूसरे के सुख-दुःख तथा भावी जीवन में साथ रहने के लिए वचनबद्ध होते है। कोल जनजाति में विवाह अनेक छोटी-छोटी रस्मों द्वारा सम्पन्न किया जाता है। मण्डप छाजन तथा मायन पूजा, मातिृका पूजन या माटी मंगल, तेल चढ़ाने की रश्म, परछन, जनवासा, द्वारचार या द्वारपूजा, ओली भराई, लावा परसवाई, सिन्दूरदान, मंगल फेरे, कन्यादान, पाँव पुजाई और कोहबर।शायद पहले इन संस्कारों को बिना पण्डित के सम्पन्न किया जाता रहा होगा किन्तु वर्तमान परिदृश्य में विवाह संस्कार में पण्डित की भूमिका शुरू से अन्त तक दिखाई देती है।शाम के समय कोल पुरुष तथा महिलाएँ मनोरंजन के लिए आंगन में मण्डप के नीचे एकत्रित होकर ढोलक आदि वाद्य यंत्रों की सहायता से गाते व बजाते हुए कोलदहका नृत्य करते है। वर वधू को वचन निभाने के लिए संकल्पित करते है। एक दूसरे के साथ सदैव सुखपूर्वक जीवनयापन की सलाह देते हैं। पहले वधू की छोटी उम्र में विवाह के बाद तीसरे, पांचवे या सातवें वर्ष जब वधू वयस्क हो जाती थी गौना सम्पन्न किया जाता था। परन्तु अब वयस्क होने के उपरान्त विवाह होने के कारण तुरन्त ही गौना भी करा लिया जाता है। जनजातियों में पुनर्विवाह में कठिनाई नहीं होती है और न ही इसे गलत माना जाता है। फिर भी किसी भी जनजाति में विवाह विच्छेद या तलाक को प्रोत्साहन नहीं दिया जाता है।

Keeping Good Company
Authors: Leuchter Shira 
Published: February 2022

A personal reflection on how Shira Leuchter’s desire to preserve existent family memories led her to create the live art performance All the Things I’ve Lost, which she performed with her mother, Joyce. All the Things I’ve Lost was commissioned by the Gardiner Museum in Toronto and premiered in August 2016. Through performing the piece, Shira discovered that casting her mother to help her recreate lost childhood objects prompted audience members to share their stories of loss with her during impromptu sessions after each performance. Acknowledging the apparent need for sharing and companioning stories of loss, Shira created the live art performance Lost Together. Lost Together premiered as part of the SummerWorks Festival Lab in 2018. While Shira and co-performer Michaela Washburn recreate and reimagine lost things for audience participants during this intimate performance, Shira recognizes that they can never be successful in resolving loss for their audience participants. Instead, they can hold the weight of the loss with their audience and offer community and connection. Shira contends that collaborating with audiences and leading with tenderness is a radical act of performing care in a culture that prizes individualism.
A brexit kalandos útvesztői – recenzió a brexit forgatókönyvei és hatásai című könyvről
Authors: Malustyik Brigitta 
Published: February 2022

A jelen recenzió tárgyául szolgáló kötet szerzői A modern állam gazdasági szerepének legújabb dimenziói elnevezésű Ludovika Kutatóműhely keretében végzett kutatásaik eredményeit mutatják be A brexit forgatókönyvei és hatásai című könyvben, kitérve annak gazdasági, kereskedelmi, pénzügyi, bel- és külpolitikai, valamint munkaerőpiaci vonatkozásaira. Bár a témával foglalkozó szakirodalom mára már rendkívül terjedelmes és sokoldalú, a kötet innovatív jellege több szempontból is megmutatkozik. Egyrészt, mert a laikus olvasó számára is érthető módon, ugyanakkor kellő tudományos megalapozottsággal mutatja be a kilépési folyamat kapcsán tárgyalandó részterületeket; másrészt pedig, mert a kötet nem csupán a brexittárgyalások előrehaladásának bemutatására törekszik, hanem a szélesebb jogi, közgazdasági és politikai összefüggéseket elemzi. Így az idő rohamos előrehaladása ellenére is érdemes a kötetet akár tankönyvként, akár ismeretterjesztő jelleggel egyéb forrásként alkalmazni, mert a tanulmányok tartalma továbbra is változatlanul időszerű.

Analyzing the Overfitting of Boosted Decision Trees for the Modelling of Stencil Printing
Authors: Martinek Péter , Krammer Oliver 
Published: February 2022

Stencil printing is one of the key steps in reflow soldering technology, and by the spread of ultra-fine-pitch components, analysis of this process is essential. The process of stencil printing has been investigated by a machine learning technique utilizing the ensemble method of boosted decision trees. The phenomenon of overfitting, which can alter the prediction error of boosted decision trees has also been analyzed in detail. The training data set was acquired experimentally by performing stencil printing using different printing speeds (from 20 to 120 mm/s) and various types of solder pastes with different particle sizes (particle size range 25–45 µm, 20–38 µm, 15–25 µm) and different stencil aperture sizes, characterized by their area ratio (from 0.35 to 1.7). The overfitting phenomenon was addressed by training by using incomplete data sets, which means that a subset of data corresponding to a particular input parameter value was excluded from the training. Four cases were investigated with incomplete data sets, by excluding the corresponding data subsets for: area ratios of 0.75 and 1.3, and printing speeds of 70 mm/s and 85 mm/s. It was found that the prediction error at input parameter values that have been excluded from the training can be lowered by eliminating the overfitting; though, the decrease in the prediction error depends on the rate of change in the output parameter in the vicinity of the respective input parameter value.
A matriz SWOT como ferramenta de análise para subsidiar a criação de consórcio intermunicipal na gestão e gerenciamento de Resíduos Sólidos Urbanos
Authors: Bozzini Aloisio Calsoni , Schalch Valdir 
Published: February 2022

Esta pesquisa teve como objetivo utilizar a matriz SWOT como ferramenta de análise para subsidiar a possibilidade de criação de um consórcio intermunicipal na gestão e gerenciamento de Resíduos Sólidos Urbanos (RSU), na microrregião da Baixa Mogiana, Minas Gerais (MG). Foi realizado um levantamento bibliográfico, e o diagnóstico da região ocorreu a partir de pesquisa documental e pesquisa de campo. A partir destes resultados foi aplicada a técnica da matriz SWOT. Os resultados apontam que: a população concentrada na área urbana, com coleta de resíduo domiciliar, bem como a presença de catadores representam uma “força”; a ausência de Usina de Triagem e Compostagem (UTC), de um aterro sanitário, a presença de lixões e aterros controlados configuram entre as “fraquezas”. Uma “ameaça” é o esvaziamento do consórcio durante a fase de implementação. A adoção de consórcio entre os municípios surge como “oportunidade” viável à medida em que alcança ganhos de escala por meio de medidas de caráter regional.
Raw Data to Results: A Hands-On Introduction and Overview of Computational Analysis for Single-Molecule Localization Microscopy
Authors: Martens Koen J. A. , Turkowyd Bartosz , Endesfelder Ulrike 
Published: February 2022

Single-molecule localization microscopy (SMLM) is an advanced microscopy method that uses the blinking of fluorescent molecules to determine the position of these molecules with a resolution below the diffraction limit (∼5–40 nm). While SMLM imaging itself is becoming more popular, the computational analysis surrounding the technique is still a specialized area and often remains a “black box” for experimental researchers. Here, we provide an introduction to the required computational analysis of SMLM imaging, post-processing and typical data analysis. Importantly, user-friendly, ready-to-use and well-documented code in Python and MATLAB with exemplary data is provided as an interactive experience for the reader, as well as a starting point for further analysis. Our code is supplemented by descriptions of the computational problems and their implementation. We discuss the state of the art in computational methods and software suites used in SMLM imaging and data analysis. Finally, we give an outlook into further computational challenges in the field.
Impacts of Metal–Support Interaction on Hydrogen Evolution Reaction of Cobalt-Nitride-Carbide Catalyst

Published: February 2022

Cobalt-nitride-carbide (Co-N-C) catalysts are promising cost-efficient transition metal catalysts for electrocatalytic hydrogen evolution, but few works investigate the metal–support interaction (MSI) effect on hydrogen evolution reaction (HER) performance. Herein, efficient Co-N-CX catalysts with controllable MSI between encapsulated Co nanoparticles and nitrogen-doped graphitic carbon nanosheets were synthesized via a facile organic–inorganic hybridization method. Results demonstrate that the Co-N-C0.025M catalyst with the coexistence of single-atom Co sites and Co nanoparticles prepared by 0.025 M cobalt nitrate shows excellent HER performance, achieving a low overpotential of 145 mV to reach 10 mA cm−2 in 0.5 M sulfuric acid, which is mainly because the optimal MSI, which leads to a moderate hydrogen adsorption energy and improved electroactive sites, not only facilitates the charge transfer to improve the HER kinetics, but also improves the durability of the catalyst by Co-N bond anchoring and encapsulation of active Co species. This work provides guidance to further reveal the influence of MSI on their catalytic activity.
Secoyanhusamine A, an Oxidatively Ring-Opened Isoquinoline Inner Salt From Corydalis yanhusuo
Authors: Wang Lingyan , Xia Huan , Wu Yuzhuo , Wang Yanan , Lin Pengcheng , Lin Sheng 
Published: February 2022

Secoyanhusamine A (1), a rare rearranged seco-isoquinoline alkaloid derived from ring oxidative cleavage, was isolated from an aqueous extract of Corydalis yanhusuo tubers, together with its biosynthetic precursor dehydrocorybulbine (2). Secoyanhusamine A (1) was the first example of a highly oxidized isoquinoline inner salt resulting in a 5-(2-azanylethyl)-2-carboxylate-4-oxo-4H-pyran ring system. The biosynthetic pathway of 1 was also postulated. Secoyanhusamine A (1) exhibited potent inhibition against acetylcholinesterase (AChE) with an IC50 value of 0.81 ± 0.13 μM. Molecular simulation docking demonstrated that 1 created a strong interaction with the Asp-74 residue of AChE via attractive charge of the quaternary nitrogen.

The hydrothermal relationship between vegetation and seasonal frozen soil is one of the key research contents in the fields of permafrost ecological environment, hydrology and climate change in alpine mountainous areas. Based on the monitoring data of air temperature, precipitation and soil hydrothermal conditions at the depth of 0–5 m from site TS-04 (with high vegetation coverage) and site TS-05 (with low vegetation coverage) in the alpine grassland of the Tianshan Mountains, this study compared and analyzed the characteristics of freezing-thawing process, temperature and moisture changes of seasonal frozen soil with different vegetation coverage. The results show that the maximum seasonal freezing depth of the two sites is almost comparable, but site TS-04 has a smaller freezing and thawing rate, and a shorter duration of freeze-thaw at all depths. TS-04 also has a smaller annual range of surface temperature and ground-air temperature difference. The analysis indicates that vegetation acts as a thermal buffer and has a good thermal insulation effect on the ground surface. Site TS-04 had high unfrozen water content in the unfrozen period and the water content increased with depth, while the unfrozen water content was low in site TS-05. In addition, the thresholds of soil water content response to rainfall events at 5 cm depth of site TS-04 and site TS-05 were 5 and 11 mm precipitation respectively, which indicated that the high vegetation coverage is conducive to rainwater infiltration, and the underlying soil of the site has a faster response to rainfall events.

Published: February 2022

The potential of a drug delivery system of the longan seed extract (LSE) incorporated in the alginate/chitosan (Alg/CS) beads has been studied. The LSE-loaded Alg/CS beads were prepared using the ionic gelation method via the interaction between protonated amino groups of CS and negatively charged carboxylic groups of Alg. Properties of the LSE-loaded Alg/CS beads were investigated including the morphology of the beads, particle sizes, encapsulation efficiency (%EE), controlled release profile, cytotoxicity, and biocompatibility. From the results, the amount of gallic acid, ellagic acid, and corilagin found in LSE was 25.61 ± 0.48,18.83 ± 3.75, and 21.92 ± 1.42 mg/g (based on the weight of LSE), respectively. The half-maximum inhibitory concentration (IC50) of LSE was 24.29 ± 1.08 μg/ml. SEM images of the LSE-loaded Alg/CS beads showed spherical shapes and rough surfaces with some aggregation. The particle sizes were between 1.9 and 2.5 µm with the PDI values of 0.1503–0.3183. Encapsulation efficiencies were between 11 and 18%. The released amount of LSE from the LSE-loaded Alg/CS beads was ranging between 68 and 93%. Moreover, cytotoxicity and biocompatibility tests showed that the beads were non-toxic to both NCTC clone 929 and NHDF cells and promoted the attachment of NHDF cells. Thus, these beads could be used as polymeric drug carriers.
