Function approximation technique (FAT)-based nonlinear control strategies for smart thin plates with cubic nonlinearities
Authors: Al-Shuka Hayder , Abbas Ehab
Published: June 2022

The current work introduces three nonlinear control solutions for the regulation of a vibrating nonlinear plate considering model uncertainty. These solutions are feedback linearization control (FBL), virtual velocity error-based control (VVEC), and backstepping control (BSC). In the FBL control, a nonlinear control law is designed with linear closed-loop dynamics such that dynamic stability is ensured. Whereas, by the VVEC (or so-called passivity-based approach in the robotics community) the limitations of the feedback linearization are overcome. On the other side, the BSC selects virtual control variables with stabilized intermediate control laws based on Lyapunov theory. Systematic modeling for the target vibrating plate with piezo patches is described. In effect, considering the nonlinear influence makes the resulted mode shapes for the vibrating structure are highly coupled and careful control design is required. Using the Galerkin approach, the partial differential equation for the smart plate is transformed into definite ordinary differential equations; the multi-input multi-output model is established. The aforementioned control strategies are evaluated and investigated in detail. In essence, they are powerful tools for dealing with nonlinear dynamic systems, however, the VVEC could be considered superior in comparison with the FBL control and the BSC since the designed control structure does not include inertia inverse matrix and modal coordinate acceleration that could make computational problems. As a result, simulation experiments were focused on the VVEC strategy, and the latter was implemented on a simply supported thin plate structure with collocated piezo-patches. The results show the validity of the proposed control architecture.
Energy-saving and performance-enhancing of a high speed on/off solenoid valve
Authors: Aborobaa Abdelfatah , Ghamry Khaled , Saleh Amr , Mabrouk Mohamed
Published: June 2022

High-speed on/off solenoid valves (HSVs) are digital vales commonly used in hydraulic power systems. These valves are usually used in pressure and flow control which requires high dynamic and energy performance to improve the control accuracy. This paper aims to propose a new control method used to improve the dynamic and energy performance of HSVs. The proposed method is based on the pulse width modulation (PWM) technique implemented by LabVIEW software and NI myRIO. Based on that, NI myRIO has a real-time module; no feedback is needed. A mathematical model of the HSV is introduced, describing each subsystem of the vale and its interactions with each other. The proposed method is validated under different operating conditions. The results show that applying the proposed control method on the HSV will reduce the valve spool closing time by 72% and reduce energy consumption by 94% compared to the traditional on/off control method.

Published: June 2022

In paper was used the panel data from the Nigeria General Household Survey and commodity prices from alternative sources between 2010-2016 to estimate farm households' food and non-food demand in Nigeria. The commodity bundles of all the food groups were necessities goods, as their budget elasticities were positive and also inelastic. Animal products were a luxury good. There is no strong complementary and substitutive relationship existing between the commodity groups as the cross price elasticities estimated were smaller than the own price elasticities. Households' expenditure on pulses is not affected by changes in their own prices. Policy issue such as stable food prices is important in ensuring that households are assisted in and encourage consuming balance diets.

Published: June 2022

Assessing the socio-economic and demographic impact of the reforms in Romanian agriculture, since 1990, on rural families, is one of the important components in the new context of the CAP, which includes new perspectives on the concept of rural family. From subsistence to sustainability, it implies the medium and long term objective of the main reforms in Romania's agriculture after the December 1989 Revolution, which were mainly represented by the start of the process of transition to market economy, by benefiting from the advantages of land rent and maybe the most important reform is Romania's accession to the EU. This paper aims to conduct an analysis of the evolution of the Romanian rural area in its many facets, focusing on the main reforms in post-December Romania agriculture, as well as the concepts of rural development in terms of sustainability and multifunctionality. In the context of a Romania that, since the accession of the EU, being considered perhaps the most important reform is the reform of agriculture, which is in the process of implementing the European model of agriculture and rural development. In order to demonstrate how the rural areas have been changed across the years, an empirical study has been assessed. It shows that there is a representative relationship between the farmers' productivity and incomes, proving how the economic prosperity of the rural citizens is determined by labour effectualness, while multiple reforms have been reshaped families' welfare.
Alternative digital currencies in international monetary law: Global stablecoins
Authors: Dimitrijević Marko
Published: June 2022

Alternative digital currencies were created to correct the shortcomings of the so-called first generation of cryptocurrencies. Their impact on the monetary order stability, systemic risk, and monetary policy strategy pursued by the Central Bank has been insufficiently examined, primarily because they are issued by large technology companies rather than the Central Bank as the custodian of monetary sovereignty. The treatment of cryptocurrencies in tort law is different from the monetary law standpoint. As such, the former is not considered in this paper because it is a private law relationship. On the other hand, monetary law refers to public law relations, including the regulatory powers of the Central Bank and the legal definition of alternative money by the provisions of the Central Bank law. As the supreme monetary institution, the Central Bank has a monopoly over the legal tender for designating and issuing money. In that sense, it would be useful to deal with the place and importance of alternative money in monetary law first, and then with other branches of private and public law. In legal terms, the acceptance and circulation of alternative money impose simultaneous (and highly demanding) consideration of the legal nature of cryptocurrency, where we can see the primacy of the social theory of money over state monetary nominalism. However, this primacy must be only temporary because the historical development of money (in all its forms) clearly shows that the emergence of any currency must sooner or later be regulated by adequate laws, for the sake of legal security and preservation of monetary stability. In a way, the accelerated technical-technological development has "caused" the existing status quo in the classical and (to some extent) the contemporary monetary law thought about how money is legally defined and who can take the role of money issuer, which has shaken the centuries-old awareness of the nature and functions of money in modern society. The circumstances that have influenced the reconsideration of already acquired habits include the emergence of reduced use of cash in circulation, the emergence of "sharing" technology that enabled the creation of cryptocurrencies, the announcement of leading technology and other multinational companies on issuing private cryptocurrencies, as well as the circumstances related to the global economic and financial crisis and the Covid-19 pandemic which point to certain advantages of alternative money.
Some disputable issues concerning the validity of testamentum allographum in Serbian judicial practice
Authors: Krstić Novak , Vidić Jelena
Published: June 2022

Testamentum allographum (an allographic will)is a written will signed by the testator and attested by two witnesses. It is one of the most common forms of written wills in Serbian legal practice. In order to ensure the validity of this will, the legislator prescribes strict formal conditions which have to be fulfilled. In practice, lawsuits for annulment of this will often refer to some contested formal deficiencies. In this paper, the authors first elaborate on the legal conditions for the validity of this will, and then analyze numerous court decisions made in the proceedings for annulment of this form of will. The authors examine in detail the positions in judicial practice on the fulfillment or non-fulfillment of the legal conditions for the validity of this written will, with reference to each element of its form. The authors emphasize the inconsistency of court practice in certain cases and discuss how the courts should have acted in specific cases. The critical analysis focuses on the court decisions in which the courts have declared the nullity of a will due to formal deficiencies, even though these shortcomings make the will voidable.
The impenetrable wall of administrative silence in Serbia
Authors: Cucić Vuk
Published: June 2022

The administrative silence, as an apparent manifestation of maladministration, has become an ever-increasing problem in Serbia. The number of administrative silence lawsuits submitted to the Administrative Court has increased more than 26 times in the last 10 years. Two potential reasons why the parties do not submit administrative appeals and administrative silence lawsuits to the Administrative Court even more often could be the lack of necessary legal knowledge (most of the parties are lay persons) or their distrust in the available legal protection mechanisms. Unfortunately, the legislator and the judiciary have undertaken measures that further aggravate the situation. This paper discusses two forms of legislative and judicial support to administrative silence, which discourage parties from using legal remedies against administrative silence and engaging lawyers. The legislator effectively supports administrative silence by, save for one exception, preventing parties from claiming damages for the damage they sustained due to the failure of competent administrative authorities to decide in their cases in a timely manner. The Administrative Court supports the administrative silence by a legal stand prescribing that a party is not entitled to reimbursement of the costs of the proceedings, including the costs of lawyer's services, provided that the first-instance administrative authority replaced its act challenged by an administrative appeal before the Administrative Court decided on the administrative silence lawsuit.
Development of a Six Degree of Freedom Velocity Prediction Program for the Foiling America's Cup Vessels
Authors: Patterson Neil , Binns Jonathan
Published: June 2022

Since the introduction of hydrofoils to the Moth sailing class in the early 2000’s foiling has become increasingly popular in sailing from windsurfers to large 75’ foiling monohulls. The last 3 America’s Cups have been competed on hydro foiling vessels. Design programs such as Velocity Prediction Programs (VPP) have become a key asset to America’s Cup teams to allow for the optimisation and testing of designs before manufacture. Presented is the development of a Six Degree-of-Freedom (6DoF) Quasi-Static Velocity Prediction Program (SVPP) and Dynamic Velocity Prediction Program (DVPP) for the 35th and 36th America's Cup foiling AC50 Catamaran and AC75 Monohull. The models have been validated against race data from the 35th and 36th America’s Cup showing good correlation for a wide wind range of 8 to 22 kn. The paper presents how the AC50 SVPP was used for analysis on the impact of Rudder Rake Differential (RRD) on overall performance, and predicting the optimal wind range for use of the light and heavy weather dagger boards on the AC50 Catamaran. The AC75 SVPP and DVPP were used to analyse the affect of hull shape and the main foils’ fixed angle-of-attack (AOA) on time-to-fight and peak velocity to determine optimal foil setup and pitch angle when foiling. The SVPP and DVPP use XFLR5 software suite to model the foils. Experimental data for a T-foil tested in the Australian Maritime College towing tank facility has been used to predict viscous and free surface effect adjustments to the predictions from XFLR5.
Towards the Dynamic Velocity Prediction of a NACRA 17
Authors: Knudsen Stig Staghoi , Walther Jens Honore , Legarth Brian Nyvang , Shao Yanlin
Published: June 2022

NACRA 17 is a small foiling catamaran used in Olympic sailing. Sailing in the NACRA 17 is truly unsteady, especially in the foiling conditions. Dynamic velocity prediction has gained a lot of attention in recent years due to the unsteady nature of foiling sailboats. Different approaches have been applied to predict the motions of foiling or skimming boats in unsteady conditions. Typically, the aerodynamic forces are computed by the quasi-steady theory assumption. Static coefficients are used and the applied velocities are corrected with boat motions. The hydrodynamic forces of a fully foiling boat can be computed in a similar fashion, but this method fails to include the effect of changes in the free surface as well as added mass. This paper proposes an approach where dynamic coefficients of the NACRA 17 hydrofoils are determined based on unsteady Computational Fluid Dynamics (CFD) simulations with a free surface. In the simulations the foil is moved in prescribed motions in one degree of freedom (DOF) at a time and dynamic coefficients are extracted for different frequencies of motion. All coefficients are combined in a coupled system of equations, and the equations can be solved in 6 DOFs in the time domain. A number of test scenarios with time varying conditions are simulated and compared with full dynamic CFD simulations. The initial investigation of the approach shows promising results, but more investigations are needed to validate the approach and to identify possible limitations.
Development of a Blockage Correction for Highly Cambered 2D Circular Arcs
Authors: Souppez Jean-Baptiste R. G. , Viola Ignazio Maria
Published: June 2022

Model-scale testing of yacht sails and wings often suffers from blockage due to the physical constraints of experimental facilities. With blockage, a greater increase in flow speed occurs in the vicinity of the geometry compared to an unblocked flow as a direct consequence of the restricted cross-sectional area. This leads to artificially higher forces, making comparison and validation between tests conducted in different facilities difficult, while also flawing performance prediction if the forces are not suitably corrected. Blockage correction for streamlined bodies and bluff bodies such as flat plates normal to the flow, are well-established. However, it is not the case for lift-generating bluff bodies, or lifting body, experiencing high trailing-edge separation, such as highly cambered plates and downwind yacht sails. This study focusses on the development of a blockage correction for highly cambered plates, specifically circular arcs, comparable to horizontal sections of downwind yacht sails. Measurements are undertaken at positive incidences below deep-stall for Reynolds numbers ranging from 53,530 to 218,000 in a towing tank and a water tunnel to devise a blockage correction. The critical impact of the free surface deformation on wake blockage is evidenced. This allows to set a maximum limit to the amount of blockage a cambered plate can experience before blockage correction is no longer accurate, hence the importance of closed measurement sections to prevent free surface deformation. Furthermore, the experiments revealed that flow behaviours such as the laminar-to-turbulent transition are preserved even with high blockage. The angle of attack at which transition occurs is also preserved in pressurized wind tunnel tests. However, the effect on the forces cannot be fully corrected, and thus further work would be needed to extend the applicability of the proposed blockage correction to such facilities. These findings provide experimental insights into the effect of blockage on highly cambered plates, and it is anticipated they will support future force experiments conducted on high-camber plates and downwind sails in water tunnels.

O Cerrado brasileiro apresenta uma certa previsibilidade em relação a pluviosidade, caracterizando-se em dois períodos: um chuvoso e outro seco. A oferta de água e seu consumo se tornam relevantes, para os diversos cultivos, isso porque a água é o principal preditor do desenvolvimento vegetal. A cultura do trigo surge como alternativa para produção no Brasil central, sendo importante sua adaptabilidade e eficiência nas condições do ambiente. O objetivo do trabalho foi submeter três cultivares de trigo, BRS264, BRS394, BRS404, indicadas para região central do Brasil, submetidas à cinco tensões hídricas: 12; 24; 36; 48 e 60kPa; em casa de vegetação, dispostos em vasos sob o delineamento em blocos ao acaso, esquema fatorial (5X3), com cinco repetições. O Monitoramento das irrigações foi a partir da leitura do sensor de capacitância (modelo- ML3, Delta T). As características avaliadas foram altura de plantas, número de espiguetas por espiga, número de grãos por espiga e índice de colheita. As cultivares BRS394 e BRS264 possuem as melhores respostas para as variáveis: altura de plantas, número de espiguetas por espiga e índice de colheita, em relação a cultivar BRS404 que demonstra menor adaptabilidade sob deficiência hídrica, A tensão hídrica do solo de 12KPa obteve os melhores resultados em relação as outras tensões.

O reconhecimento das espécies nativas remanescentes e as relações ecológicas entre elas na etapa inicial do manejo agroflorestal se torna indispensável, para fins de compreensão do papel de cada espécie, dos serviços ecossistêmicos destas e as possíveis relações com as espécies a serem introduzidas. Nesse sentido, o objetivo desta pesquisa foi reconhecer a composição florística natural e suas relações ecossistêmicas em área de Caatinga nativa como etapa essencial de implantação e sugestão de modelo de agrofloresta, considerando uma maior oferta de serviços ecossistêmicos. A metodologia utilizada se deu por meio do Levantamento florístico, fitossociológico e fitossanitário, onde para o levantamento florístico partiu da inventariação de dados florestais in loco. Para o levantamento fitossociológico foram calculados os referidos diâmetros a altura do peito (DAP), Número total de Indivíduos (NI), Densidade Relativa (DRe), Área Basal (AB), Frequência Relativa (FeR), Dominância Relativa (DoR), Valor de Importância (VI), Valor de Cobertura (VC), Índice de Diversidade de Shannon-Weaver (H’) e equitabilidade de Pielou (J’). E o levantamento fitossanitário foi utilizado metodologia adaptada do índice de condição geral das árvores, coletando informações de fitossanidade, injúrias, necroses e infestações gerando por fim o índice baseado na média aritmética ponderada do número de indivíduos dentro de uma das classes de sanidade boa, satisfatória, ruim ou morta. Os resultados obtidos inferem que as espécies inventariadas apresentaram bom estado fitossanitário e fenotípico em boas condições ambientais, distribuídas em diferentes famílias botânicas de hábitos distintos. O referido índice demonstrou relevância na avaliação ambiental corroborando com dados florísticos e fitossociológicos coletados em campo, auxiliando na definição de SAF sucessional como melhor alternativa de transição.

O babaçu (Orbignya phalerata Mart.) tem uma ocorrência elevada em algumas partes da Amazônia, mas raramente é usado pela população regional, podendo ser um fator de desenvolvimento econômico e social na região, como ocorre comumente no Estado do Maranhão. Para que isso ocorra, torna-se necessário aproveitar o mesocarpo, rico em amido, em produtos ou subprodutos que sirvam de base de suprimento de matéria prima para bioindústrias capazes de converter esses compostos em algo de maior valor econômico. Foram realizados experimentos de laboratório com 40 rizobactérias, avaliando-se seus crescimentos em meio de cultura contendo manitol (controle) e, em meio contendo farinha de babaçu em duas temperaturas, 27 °C e 55 °C.  Os principais resultados indicaram que das 40 rizobactérias testadas, as com maiores crescimentos no meio contendo farinha de babaçu foram as INPA R236, INPA R262, INPA R266, INPA R269, INPA R015, INPA R296 e INPA R689. Nenhuma das 40 rizobactérias apresentou crescimento visível nas placas de Petri contendo meio com farinha de babaçu à temperatura de 55 °C.
Titanium in commercial shrimp from anthropized tropical bays and estimated quantities of TiO2

Published: June 2022

Titanium (Ti) is a metal with low toxicity in organisms; however, Ti in the form of TiO2 nanoparticles is a contaminant of emerging concern. This study determined the concentration of total Ti in the muscle of pink shrimp (Penaeus brasiliensis and P. paulensis) from two anthropized tropical bays (Guanabara and Sepetiba Bays, southeast Brazil) and presented the first estimates of TiO2 in shrimp. Differences in the total Ti concentration were associated with fishing site and season, showing a spatial-temporal trend. The level of anthropization per se did not explain the metal concentration. Both trophic position (Î´15N) and trophic habitat (Î´13C) of shrimp had negligible influence on the metal concentration. We suggest that Ti point sources into Sepetiba Bay and/or differences regarding fishing sites inside the bays are possible explanations for the results. The estimates of TiO2 in shrimps based on the total Ti concentration are baseline values for future monitoring. Since shrimps are targets of commercial fisheries, monitoring the Ti concentration is a public health interest.

O ofício dos catadores de materiais recicláveis é descrito como insalubre, e permeada por uma ampla variedade de agravos entre estes o contato com agentes biológicos vetores de doenças a portadores de peçonha. Posto isto, a corrente pesquisa almeja analisar a relação da fauna sinantrópica nociva como ameaça à saúde dos trabalhadores da Associação de Catadores de Materiais Recicláveis da Comunidade Nossa Senhora Aparecida (ARENSA). Para esta finalidade o estudo decorreu em três etapas de desenvolvimento, que abrangem: a aplicação de questionários sócio-demográficos, seguido de coletas de espécimes sinantrópicas in situ entre agosto de 2019 a fevereiro de 2020, e por fim, a identificação dos espécimes com auxílio de chaves taxonômicas. O público entrevistado caracterizou-se como uma população vulnerável, compelida ao ofício de catadores de materiais recicláveis como alternativa de subsistência, além disso, segundo os relatos, pode-se constatar que ocorre uma alta exposição dessa aos mais variados agravos de cunho biológico, como os relatos de envenenamento por escorpionismo em acidentes em 21% (3) dos colaboradores. A incidência sinantrópica comprovada por meio de coleta se concentrou em 7 (sete) famílias: Salticidae, Uloboridae, Pholcidae, Theridiidae, Muscidae, Calliphoridae e Blatidae. Destacando-se as famílias Muscidae, Calliphoridae e Blattidae, responsáveis pela disseminação de uma ampla gama de patógenos relacionados a adoecimentos relatados no cotidiano dos colaboradores. Como fatores que influenciam este cenário, ressalta-se a ausência de dedetizações e medidas de controle da fauna sinantrópica ao longo da história da ARENSA, potencializados pela falta de seleção dos resíduos sólidos por parte da fonte geradora. Essas são competências compartilhadas com o a fonte geradora e o Estado através do SUS e da vigilância sanitária.

Published: June 2022

O monitoramento ambiental de microbacias hidrográficas possibilita diagnosticar as alterações no uso e ocupação do solo, tornando possível avaliar os efeitos das atividades humanas sobre os ecossistemas. A aplicação de instrumentos de avaliação de alguns parâmetros físicos do habitat,características da água, dos sedimentos e da cobertura que sejam sensíveis às alterações do ambiente pode contribuir fortemente para a conservação das microbacias. O objetivo desse trabalho foi avaliar o estado de conservação de pontos da microbacia do ribeirão Mantiqueira inserida nas comunidades Sarandi e Indaiá no município de Luziânia em Goiás, utilizando um Protocolo de Avaliação Rápida (PRAVIA) para a região do Brasil Central, e o Índice de Qualidade de água (IQA). Observou-se qualidade das águas dos tributários alterada e impactada. Todavia, os dois últimos pontos mais próximos da foz do ribeirão Mantiqueira apresentaram classificação natural segundo avaliação do PRAVIA. Uma melhoria da qualidade do ambiente alterado e impactado para natural, nos dois últimos pontos próximo à foz, contribuiu para uma pequena diminuição dos valores de IQA, porém a classificação se manteve em um índice “qualidade Boa” da água. Escassez de cobertura vegetal nativa para o solo, implica em erosão. Nos trechos estudados foram observados processos erosivos de diversas intensidades, de erosão laminar moderada a ravinas e voçorocas, e consequente, assoreamento dos cursos d’água. Por outro lado, ambientes considerados naturais foram aqueles com presença de Mata de Galeria com cobertura vegetal no leito, árvores de porte mais altos (>8m) e fluxo de água perene. O protocolo PRAVIA, como ferramenta de análise da qualidade ambiental, demonstrou de fácil aplicação, simples, rápido e de baixo custo, e que pode ser utilizado pelos pequenos agricultores de forma participativa e integrada para monitoramento e tomada de decisão sobre o manejo de microbacias hidrográficas, visando à conservação dos seus recursos hídricos.

This paper reinterprets these transformations, departing from notions of ‘relational space’, re-conceptualizing urban spaces as mobile and relational, continuously reconstructed and reground ed by flows of people, knowledge, and capital. We examine the representations of mobility and the embodied mobile practices in relation to the ongoing mutation of a Barcelona's neigh borhood, in which the urban transformations linked to the 1992 Olympic Games, the renewal of the waterfront and the later development of a hi-tech cluster has triggered a profound and long-lasting process of social change.

THE PORTUGUESE’S BEHAVIOR TOWARDS TRAVEL AGENCIES
Authors: Gavina Beatriz , Silva Susana
Published: June 2022

It is stated that tourism has greatly grown in Portugal. Thus, one must ponder if the Portuguese use traditional travel agencies or online travel agencies. As such, the main objective of this study is to characterize the Portuguese’s behavior towards travel agencies, hence the use of a quantitative methodology. Gender, income, and promotions influence the Portuguese’s decision on whether to purchase in a specific type of travel agency, being that price is not the most relevant factor. While this study is relevant to the current lack of literature, there must be further studies on this theme.

Se afirma que el turismo ha crecido mucho en Portugal. Por lo tanto, hay que reflexionar si los portugueses utilizan las agencias de viajes tradicionales o las agencias de viajes online. Por ello, el objetivo principal de este estudio es caracterizar el comportamiento de los portugueses hacia las agencias de viajes, de ahí que se utilice una metodología cuantitativa. El género, la renta y las promociones influyen en la decisión de los portugueses sobre la compra en un determinado tipo de agencia de viajes, siendo el precio el factor menos relevante. Si bien este estudio es relevante para la actual falta de literatura, deben realizarse más estudios sobre este tema.

The importance of cultural globalization in the creation and aesthetic orientation of Chinese painting

Chinese painting has always been a unique product of our ancient civilization, which has survived to the present day. During its 2000-year development, Chinese painting has gradually turned into a unique and non-reproducible art form capable of expressing the thoughts and feelings of the artist. Over time, Chinese painting also demonstrates a new trend of inheritance and innovative development. Changes in Chinese painting occur simultaneously with the processes of globalization. This gives rise to new research on the trends of diversification of artistic creativity. The focus of artistic expression has shifted from the depiction of direct natural objects towards the spiritual plane, which is a direct result of the creative activity of artists whose aspirations are manifested in the use of traditional Chinese ink painting in combination with new methods of figurative representation and deep understanding of spiritual content. Since ancient times, artists have actively sought to harmonize and balance the subjective and objective, as well as to achieve their organic combination. This article examines traditional Chinese painting as a source and driving force of the transformation of Chinese painting、prints of the era and integration in the content of paintings、attempts to introduce the Western concept of frontal composition, as well as updating the language of painting and artistic concepts. It is argued that the fundamental driving force and the main support for the development of Chinese painting in the context of globalization should be traditions integrated with new creative elements and techniques, thus it is possible to better promote Chinese culture and inherit the essence of traditional Chinese painting.

The vacuole has a space-filling function, allowing a particularly rapid plant cell expansion with very little increase in cytosolic content (Löfke et al., 2015; Scheuring et al., 2016; Dünser et al., 2019). Despite its importance for cell size determination in plants, very little is known about the mechanisms that define vacuolar size. Here, we show that the cellular and vacuolar size expansions are coordinated. By developing a pharmacological tool, we enabled the investigation of membrane delivery to the vacuole during cellular expansion. Our data reveal that endocytic membrane sorting from the plasma membrane to the vacuole is enhanced in the course of rapid root cell expansion. While this ‘compromise’ mechanism may theoretically at first decelerate cell surface enlargements, it fuels vacuolar expansion and, thereby, ensures the coordinated augmentation of vacuolar occupancy in dynamically expanding plant cells.
Systematic lncRNA mapping to genome-wide co-essential modules uncovers cancer dependency on uncharacterized lncRNAs

Quantification of gene dependency across hundreds of cell lines using genome-scale CRISPR screens has revealed co-essential pathways/modules and critical functions of uncharacterized genes. In contrast to protein-coding genes, robust CRISPR-based loss-of-function screens are lacking for long noncoding RNAs (lncRNAs), which are key regulators of many cellular processes, leaving many essential lncRNAs unidentified and uninvestigated. Integrating copy number, epigenetic, and transcriptomic data of >800 cancer cell lines with CRISPR-derived co-essential pathways, our method recapitulates known essential lncRNAs and predicts proliferation/growth dependency of 289 poorly characterized lncRNAs. Analyzing lncRNA dependencies across 10 cancer types and their expression alteration by diverse growth inhibitors across cell types, we prioritize 30 high-confidence pan-cancer proliferation/growth-regulating lncRNAs. Further evaluating two previously uncharacterized top proliferation-suppressive lncRNAs (PSLR-1, PSLR-2) showed they are transcriptionally regulated by p53, induced by multiple cancer treatments, and significantly correlate to increased cancer patient survival. These lncRNAs modulate G2 cell cycle-regulating genes within the FOXM1 transcriptional network, inducing a G2 arrest and inhibiting proliferation and colony formation. Collectively, our results serve as a powerful resource for exploring lncRNA-mediated regulation of cellular fitness in cancer, circumventing current limitations in lncRNA research.

Introduction: Spinal anaesthesia is the preferred anaesthetic technique for fractures of the hip and femur. Ultrasound-guided Fascia Iliaca Compartment Block (FICB) provides more intense analgesia which can prolong the duration of postoperative analgesia and also mitigate the pain encountered while positioning for spinal anaesthesia. Aim: To evaluate the efficacy of ultrasound-guided pre-emptive FICB in hip and femur fracture surgeries. Materials and Methods: This randomized, double-blinded, clinical study was conducted between May 2019 and December 2019, at SRM Medical College Hospital and Research Centre, Chennai, Tamil Nadu, India. Total 66 patients scheduled for hip and femur fracture surgeries under spinal anaesthesia were randomly divided into two groups i.e, group A received Ultrasound-Guided (UG) FICB preoperatively and group B received no block. All the patients received fentanyl 1 mcg/kg intravenous (i.v.) 15 min before spinal anaesthesia. The anaesthesiologist performing spinal anaesthesia graded the score of positioning as 0 as not satisfactory, 1 as satisfactory, 2 as good, 3 as optimal. The time for the first request for analgesia, consumption of analgesics and Visual Analog Scale (VAS) scores for 24 hours postoperatively and any adverse effects were compared between the two groups. Student’s t-test was used to compare continuous data and unpaired t-test for categorical data. Results: The time for the first request for analgesia was 671.52±66.73 min in group A and 480.3±57.65 min in group B and was statistically significant (p-value <0.0001). In group A, the quality of positioning for spinal anaesthesia was optimal in 13 and good in 14 patients. In group B, it was unsatisfactory in 12 and just satisfactory in four patients (p-value=0.0009). Majority of the patients (24) in group A required three doses of paracetamol, while 26 patients required two doses for group B. The total number of doses for tramadol was 4 in group A, and 17 in group B. The VAS scores were reduced at the 8th and 10th hours following surgery in group A. No adverse effects were encountered in the study. Conclusion: The FICB prolongs the time to first request for analgesia postoperatively, improves patient positioning for spinal anaesthesia, reduces the consumption of analgesics, and improves VAS scores postoperatively without any adverse effects.
