Nest architecture and colony composition in two populations of Ectatomma ruidum sp. 2 (E. ruidum species complex) in southwestern Colombia
Authors: Santamaría Carlos , Armbrecht Inge , Lachaud Jean-Paul
Published: February 2022

Nest architecture plays a fundamental role in the adaptation of ants to their habitat, favoring the action of economically important species. Ectatomma ruidum sp. 2 (ruidum species complex) is a biological control agent in Neotropical agroecosystems, exhibiting high bioturbation impact due to high nest densities. The architecture and composition of 152 nests were studied in two Andean populations of southwestern Colombia, 24 of them being cast using the paraffin wax technique. Nest entrance was a single, circular, 4 mm hole at ground level, without any special external structure, connected to a single vertical tunnel communicating with successive half ellipsoidal chambers. Nests were extremely shallow (depth range: 28.7–35.4 cm), with an average of six chambers and an overall volume of 92.2 cm3 per nest. The deeper the chamber, the smaller its volume. Nest building was independent of plants or roots, and no surface or underground physical connections were found between neighboring nests. Few nests possessed a queen, and neither ergatoids nor microgynes were recorded. Despite significant interactions between localities and the number of both males and workers, queen presence had an overall highly positive effect on the number of workers and larvae and a negative one on the number of gynes. Overall, the studied Colombian populations of E. ruidum sp. 2 retained the simple nest structure described for other species of this species complex and for colonies of the same species from other geographical areas, though they constrasted in their extreme shallowness. Our data suggest that E. ruidum sp. 2, at the local level, does not follow the usual monodomic pattern of this species with facultative polygyny but, rather, has a polydomic pattern with monogyny, perhaps related to the extreme shallowness of the nests due to soil structure, which could significantly enhance the queen’s reproductive inhibition previously reported for this species.

Authors: Petrović Vladimir , Vuković Vladimir , Patić Aleksandra , Marković Miloš , Ristić Mioljub
Published: February 2022

Background

Mass vaccination is the key element in controlling current COVID-19 pandemic. Studies comparing immunogenicity of different COVID-19 vaccines are largely lacking. We aimed at measuring anti-S antibody (Ab) levels in individuals fully vaccinated with BNT162b2, BBIBP-CorV and Gam-COVID-Vac, as well as in COVID-19 convalescents.

Methods

In this cross-sectional study, serum was collected from 400 age- and sex-matched participants, 100 fully vaccinated with BNT162b2, 100 with BBIBP-CorV and 100 with Gam-COVID-Vac on the 28th day after the second vaccine dose, and 100 recovered from COVID-19 at least 28 days after symptom(s) resolution. Sera were analyzed using the LIAISON SARS-CoV-2 S1/S2 IgG assay (DiaSorin, Saluggia, Italy). Wilcoxon rank-sum or Kruskal–Wallis tests was used for comparison of Ab levels.

Results

Highest mean value (210.11, SD = 100.42) was measured in the BNT162b2 group, followed by Gam-COVID-Vac (171.11, SD = 120.69) and BBIBP-CorV (68.50, SD = 72.78) AU/mL (p<0.001). Significant differences in antibody levels were found between BNT162b2 and BBIBP-CorV (p<0.001), BNT162b2 and Gam-COVID-Vac (p = 0.001), as well as BBIBP-CorV and Gam-COVID-Vac groups (p<0.001). Percentage of seropositive was 81% in the convalescent group, 83% in BBIBP-CorV vaccinated and 100% in BNT162b2 and Gam-COVID-Vac. When comparing measured antibody levels in vaccinated to those in COVID-19 recovered, significantly higher antibody levels were found for vaccinated with BNT162b2 (p<0.001), and with Gam-COVID-Vac (p<0.001), while for BBIBP-CorV there was no statistically significant difference (p = 0.641).

Conclusions

All three investigated vaccines, BNT162b2, BBIBP-CorV and Gam-COVID-Vac, provide robust immune response 28 days after the second dose of vaccine, in the majority of participants. All individuals vaccinated with BNT162b2 and Gam-COVID-Vac seroconverted, while in vaccinated with BBIBP-CorV and COVID-19 recovered seroconversion rates were lower. Although less potent compared to other two vaccines, immune response after BBIBP-CorV was similar to response measured in convalescents. Challenge still remains to examine dynamics and durability of immunoprotection.

El Poder Local y la Modernización Autoritaria en Granada.
Authors: Hidalgo Álvarez Roque , Morente Muñoz Carmen , Pérez Serrano Julio
Published: February 2022

Después de cinco años de administración local bajo la presidencia del marqués de Casablanca ninguno de los proyectos de modernización de Granada había comenzado. El alcalde-presidente se negó a solicitar empréstitos a entidades bancarias. Tras su dimisión un nuevo Ayuntamiento presidido por el abogado Mariano Fernández Sánchez-Puerta fue cooptado por el Directorio Civil para ejecutar los proyectos.  Las prioridades fueron el alcantarillado, el agua potable, el ensanche de la ciudad y la construcción de un Camino de Ronda. El coste de la modernización se estimó en treinta y dos millones y medio de pesetas, incluyendo los dieciséis y medio del proyecto prioritario del alcantarillado y aguas potables. Tanto en la operación del empréstito como en la adjudicación de la contrata se aceptó la oferta más barata que pronto se demostró inviable. La modernización autoritaria impulsada por el Ayuntamiento no alcanzó ninguno de sus objetivos iniciales y resultó un rotundo fracaso

Published: February 2022

Tradicionalmente, el negocio del vino ha sido una de las principales actividades económicas desarrolladas en la provincia de Cádiz, cobrando especial relevancia desde mediados del siglo XIX, época de crecimiento y prosperidad. Sin embargo, hacia finales de esa centuria, la llegada de una crisis al sector vitivinícola andaluz traería consigo serias dificultades para las empresas vinateras de la región, entre las que se encontraba Lacave y Compañía, objeto de este estudio. A partir del análisis de su contabilidad, la documentación de los protocolos notariales, los padrones y censos de extranjeros y otras publicaciones de la época, se tratará de conocer cómo desarrollaba su actividad vitivinícola a finales de la centuria decimonónica esta compañía. Concretamente, se pretende analizar cuáles fueron las estrategias desarrolladas por esta sociedad mercantil para hacer frente a las dificultades del sector en esos años de crisis, así como la efectividad de las mismas.

Objective: The present study aimed to evaluate the effect of baseline frailty status (as measured by modified frailty index-5 [mFI-5]) versus age on postoperative outcomes of patients undergoing surgery for spinal tumors using data from a large national registry.Methods: The National Surgical Quality Improvement Program database was used to collect spinal tumor resection patients’ data from 2015 to 2019 (n = 4,662). Univariate and multivariate analyses for age and mFI-5 were performed for the following outcomes: 30-day mortality, major complications, unplanned reoperation, unplanned readmission, hospital length of stay (LOS), and discharge to a nonhome destination. Receiver operating characteristic (ROC) curve analysis was used to evaluate the discriminative performance of age versus mFI-5.Results: Both univariate and multivariate analyses demonstrated that mFI-5 was a more robust predictor of worse postoperative outcomes as compared to age. Furthermore, based on categorical analysis of frailty tiers, increasing frailty was significantly associated with increased risk of adverse outcomes. ‘Severely frail’ patients were found to have the highest risk, with odds ratio 16.4 (95% confidence interval [CI],11.21–35.44) for 30-day mortality, 3.02 (95% CI, 1.97–4.56) for major complications, and 2.94 (95% CI, 2.32–4.21) for LOS. In ROC curve analysis, mFI-5 score (area under the curve [AUC] = 0.743) achieved superior discrimination compared to age (AUC = 0.594) for mortality.Conclusion: Increasing frailty, as measured by mFI-5, is a more robust predictor as compared to age, for poor postoperative outcomes in spinal tumor surgery patients. The mFI-5 may be clinically used for preoperative risk stratification of spinal tumor patients.

Published: February 2022

Objective: The aim of this study was to compare the clinical and radiologic outcomes of 3 types of minimally invasive posterior cervical foraminotomy (PCF): uniportal endoscopic surgery, biportal endoscopic surgery, and microsurgery.Methods: Between January 2019 to January 2020, PCF was performed using 3 different approaches to treat foraminal stenosis. The foraminal expansion rate, facet resection rate, and surgical foraminal approach angle were measured using magnetic resonance imaging. Visual analogue scale (VAS) scores for neck and arm pain, neck disability index (NDI), MacNab criteria, operation time, hospital stay, and complications were assessed. Clinical and radiologic parameters were compared among the 3 surgical groups.Results: There were 38, 30, and 50 patients in the uniportal endoscopy, biportal endoscopy, and microscopy groups, respectively. Microscopy group displayed significantly higher foraminal expansion compared to uniportal endoscopy group (p = 0.001). Facet resection rates and inclination angle for facet joint undercutting were significantly different among the 3 groups. Uniportal endoscopy group had the highest inclination angle and the least facet resection. On the 6 months and final follow-up, VAS scores and NDI were significantly lower in the uniportal endoscopy group than in the microscopy group (p = 0.000).Conclusion: All 3 types of PCF displayed favorable clinical outcomes and sufficient expansion of the midforaminal area. Two endoscopy groups showed a significantly higher inclination angle for undercutting the facet joint and a lower facet resection rate than the microscopy group. Reduced facet joint resection using an inclinatory approach did not interfere with sufficient foraminal expansion and enhanced the clinical result after 6 months of follow-up.

Published: February 2022

Spinal cord gliomas are rare entities that often have limited surgical options. Immunotherapy has shown promise in intracranial gliomas with some research suggesting benefit for spinal cord gliomas. A focused review of immunotherapies that have been investigated in spinal cord gliomas was performed. The primary methods of immunotherapy investigated in spinal cord gliomas include immune checkpoint inhibitors, adoptive T-cell therapies, and vaccine strategies. There are innumerable challenges that must be overcome to effectively apply immunotherapeutic strategies to the spinal cord gliomas including low incidence, few antigenic targets, the blood spinal cord barrier, the immunosuppressive tumor microenvironment and neurotoxic treatment effects. Nonetheless, research has suggested ways to overcome these challenges and treatments have been effective in case reports for metastatic non-small cell lung cancer, melanoma, midline glioma and glioblastoma. Current therapies for spinal cord gliomas are markedly limited. Further research is needed to determine if the success of immunotherapy for intracranial gliomas can be effectively applied to these unique tumors.
„Fény és árnyék” nemzetközi kitekintésben: A turizmus két oldala - nemcsak a turista lehet áldozat…
Authors: Ernszt Ildikó
Published: February 2022

A vágyak iparágában, azaz a turizmusban mindenki megpróbálja a saját álmait valóra váltani. Ez azonban nemcsak idegen kultúrák, emberek, a földi tájak szépségének a megtapasztalását jelenti sokak számára, hanem mások kihasználását, mások szenvedéséből való gazdagodást, vagy egyszerűen a helyi közössé­gek érdekeinek a semmibe vételét. A cikkben annak a vizsgálatára kerül sor, hogy melyek azok a negatív jelenségek, amelyek a turistákkal együtt megjelennek a desztinációkban, és a helyi lakosság biztonságát veszélyeztetik. Ugyanis az iparág érthető okokból rendkívül „turista-, azaz vendégcentrikus”, és hajlamos teljes mértékben elfelejtkezni a másik oldalról: a vendéglátókról. Holott a turisták sok esetben rossz vendég módjára „lerohanják” a desztinációkat, törnek-zúznak, randalíroznak, és nemcsak a pénztárcájukat hozzák a „bőröndjeikben”, hanem a sötét vágyaikat is. Olyanok pedig mindig voltak, és lesznek is, akik ezeket az ördögi szenvedélyeket – természetesen jó pénzért – kielégítik. Az úti célok lakosságának leginkább veszé­lyeztetett csoportjai közé a gyermekek, nők, idősek tartoznak, akik a sérülékenységüknek köszönhetően még könnyebben áldozattá válhatnak. A cikk a teljesség igénye nélkül említ meg néhány, a desztinációkban élő lakosság biztonságát veszélyeztető jelenséget, bűncselekményt: a szexturizmust, ezzel kapcsolatban kü­lön kiemelve a gyermekprostitúciót, illetve a gyermekmunka és gyermekkereskedelem bűntettét. Végezetül javaslatok tételére is sor kerül a vendéglátók védelme érdekében, hiszen ennek elmulasztása esetén nagy árat kell fizetnünk.

Az elmúlt évtizedben a városi turizmus kínálatában a hagyományos elemek mellett új, innovatív termé­kek jelentek meg. A kreatív turizmus különösen olyan desztinációk esetében fejlődik gyorsan, amelyek az élményszerzés és aktivitás új, alternatív formáit keresik és alkalmazzák. A kreatív turizmus egyik új fej­lődési iránya a gamifikáció, amikor egy játék áll a turisztikai aktivitás középpontjában, és új vonzerőként ez szolgáltat emlékezetes élményeket a turisták számára. Napjainkban a kreatív turizmus és gamifikáció egyik nemzetközi szinten is legnépszerűbb szolgáltatása a szabadulószoba, amelynek európai meghono­sításában a magyar szolgáltatók úttörő szerepet játszottak. Tanulmányunkban longitudinális internetes weboldalelemzés, tartalomelemzés, terepbejárás és empirikus megfigyelések eredményein keresztül először rendszerezzük és kategorizáljuk Budapest kreatív turisztikai kínálatát, majd részletesen bemutatjuk a szabadulószoba szolgáltatások kínálati piacát és a szabadulójátékok legfontosabb jellemzőit. A nemzetközi összehasonlítás és konkurenciaelemzés segítségével a budapesti szabadulószoba-piac nemzetközi verseny­képességét és pozícióját elemezzük.
Methodologies for decolonising geography curricula in the secondary school and in initial teacher education
Authors: Nayeri Cyrus , Rushton Elizabeth A.C.
Published: February 2022

While a clear rationale for the need to decolonise school geography curricula has been proposed, there are few examples of what this looks like in practice. Drawing on our professional practice in both a secondary school and a university setting, we outline two case studies of decolonising the curriculum that centre on promoting student agency. The first is a Year 7 geography unit of work, and the second is a walking tour of London for an initial teacher education programme for secondary school geography teachers. Through these case studies, we argue for the importance of encouraging students to think about geographical relations with other places, and build on studies which foreground the importance of place as a pedagogic device through which the aims of decolonisation can be furthered.
Spatiotemporal Temperature Fusion Based on a Deep Convolutional Network
Authors: Wang Xuehan , Shao Zhenfeng , Huang Xiao , Li Deren
Published: February 2022

High-spatiotemporal-resolution land surface temperature (LST) images are essential in various fields of study. However, due to technical constraints, sensing systems have difficulty in providing LSTs with both high spatial and high temporal resolution. In this study, we propose a multi-scale
spatiotemporal temperature-image fusion network (MSTTIFN) to generate high-spatial-resolution LST products. The MSTTIFN builds nonlinear mappings between the input Moderate Resolution Imaging Spectroradiometer (MODIS) LSTs and the out- put Landsat LSTs at the target date with two pairs
of references and therefore enhances the resolution of time-series LSTs. We conduct experiments on the actual Landsat and MODIS data in two study areas (Beijing and Shandong) and compare our proposed MSTTIFN with four competing methods: the Spatial and Temporal Adaptive Reflectance
Fusion Model, the Flexible Spatiotemporal Data Fusion Model, a two-stream convolutional neural network (StfNet), and a deep learning-based spatiotemporal temperature-fusion network. Results reveal that the MSTTIFN achieves the best and most stable performance.

Published: February 2022

O presente artigo foi elaborado a partir de estudos do grupo sobre Vigotski e Marx do LIEPPE para defender a pertinência da Psicologia Histórico-Cultural, perspectiva teórica capaz de subsidiar a compreensão das relações entre Psicologia e Educação, de modo a instrumentalizar a prática de psicólogos/as e professores/as. Apresenta os pressupostos teórico-metodológicos que orientam o estudo, delineando quatro teses, resultantes de um amplo trabalho de síntese. Propõe a concepção materialista histórica dialética que permite tanto superar concepções hegemônicas de Psicologia que, tradicionalmente, buscam as causas do fracasso escolar nos processos individuais, quanto concepções que abdicam de sua especificidade teórico-metodológica como ciência, privilegiando a denúncia dos problemas do contexto escolar em detrimento da instrumentalização conceitual dos processos pedagógicos. Essa perspectiva possibilita aos/às trabalhadores/as da Psicologia Escolar uma atuação comprometida com a emancipação humana, que só será alcançada por meio da superação do modo de produção capitalista rumo à construção de uma nova sociedade.

Atividade de estudo como conceito central para a psicologia escolar
Authors: Asbahr Flávia da Silva Ferreira , Mendonça Ana Bárbara Joaquim
Published: February 2022

A Psicologia Escolar em uma perspectiva crítica, historicamente, buscou superar a culpabilização dos estudantes frente às dificuldades de aprendizagem e compreender o processo de escolarização em suas múltiplas determinações. No entanto, avalia-se que a fim de não permanecermos apenas no lugar da crítica e da denúncia ao fracasso escolar, necessitamos também desenvolver teórica e praticamente meios que possam instrumentalizar uma atuação propositiva. Dessa forma, este ensaio visa apresentar a atividade de estudo enquanto um conceito fundamental à atuação da/o psicóloga/o escolar que se orienta a partir da Psicologia Histórico-Cultural. Para tanto, busca inicialmente justificar a necessidade do conceito e, em um segundo momento, apresentar o que é atividade de estudo, como esta se forma e se estrutura. Por fim, propõe-se a articular este conceito com a atuação da Psicologia Escolar.
As possibilidades de crise inscritas na reprodução do capital social
Authors: Cris de Aquino Dayani
Published: February 2022

Este artigo tem como objetivo analisar o processo de reprodução do capital social a fim de identificar em quais pontos deste processo as possibilidades de crise estão inscritas. Trata-se de uma análise teórica acerca das crises econômicas que resgata o método de investigação de Marx tomando como instrumental de análise o conceito de contradição. Primeiro, apresenta-se uma revisão do significado do termo contradição nas obras de Marx e em especial nos trechos em que o autor se ocupa da análise das possibilidades de crise. Em seguida utilizam-se os esquemas da reprodução de Marx a fim de identificar os pontos nos quais contradições existentes colocam possibilidades de crise inscritas na reprodução do capital social. Assim, conclui-se que o entendimento das crises concretas, portanto, reais, requerem diversas mediações, as quais não estão contempladas nos esquemas de reprodução dada sua natureza abstrata.
Taxa de lucro e acumulação de capital no Brasil: concepções teóricas, análise histórica e relação de causalidade
Authors: De Abreu Grazziotin Henrique , Fornari Ana Paula , Marquetti Adalmir Antonio
Published: February 2022

O presente trabalho analisa a relação entre a taxa de lucro e a acumulação de capital a partir de perspectivas teórica e empírica. Na teórica, discutimos as principais abordagens sobre o papel da lucratividade na análise macroeconômica, com ênfase na economia política marxiana. Na empírica, apresentamos uma breve descrição histórica da evolução da taxa de lucro e da taxa de acumulação para o Brasil entre 1953 e 2017, avaliando seus componentes por meio da decomposição de Weisskopf (1979). Por fim, aplicamos o procedimento de Toda e Yamamoto (1995) para testar a hipótese de não causalidade de Granger nas variáveis taxa de lucro e taxa de acumulação de capital. Os resultados são consistentes com a presença de causalidade de Granger unidirecional da taxa de lucro para a taxa de acumulação no Brasil entre 1953 e 2017.

Arctic observing and data systems have been widely recognized as critical infrastructures to support decision making and understanding across sectors in the Arctic and globally. Yet due to broad and persistent issues related to coordination, deployment infrastructure and technology gaps, the Arctic remains among the most poorly observed regions on the planet from the standpoint of conventional observing systems. Sustaining Arctic Observing Networks (SAON) was initiated in 2011 to address the persistent shortcomings in the coordination of Arctic observations that are maintained by its many national and organizational partners. SAON set forth a bold vision in its 2018 – 28 strategic plan to develop a roadmap for Arctic observing and data systems (ROADS) to specifically address a key gap in coordination efforts—the current lack of a systematic planning mechanism to develop and link observing and data system requirements and implementation strategies in the Arctic region. This coordination gap has hampered partnership development and investments toward improved observing and data systems. ROADS seeks to address this shortcoming through generating a systems-level view of observing requirements and implementation strategies across SAON’s many partners through its roadmap. A critical success factor for ROADS is equitable participation of Arctic Indigenous Peoples in the design and development process, starting at the process design stage to build needed equity. ROADS is both a comprehensive concept, building from a societal benefit assessment approach, and one that can proceed step-wise so that the most imperative Arctic observations—here described as shared Arctic variables (SAVs)—can be rapidly improved. SAVs will be identified through rigorous assessment at the beginning of the ROADS process, with an emphasis in that assessment on increasing shared benefit of proposed system improvements across a range of partnerships from local to global scales. The success of the ROADS process will ultimately be measured by the realization of concrete investments in and well-structured partnerships for the improved sustainment of Arctic observing and data systems in support of societal benefit.

Desde o início da pandemia do novo coronavírus (Covid-19) no Brasil, profissionais de saúde residentes, entre eles o farmacêutico, estão desempenhando um papel fundamental na adoção de estratégias para minimizar os impactos da pandemia. O presente estudo tem como objetivo descrever as experiências vivenciadas por um farmacêutico residente vinculado ao programa de residência multiprofissional em saúde da família durante ações de testagem rápidas para Covid-19 realizadas no o município de Aracaju-SE. As ações foram realizadas em vários bairros da capital, de segunda a sexta-feira, obtendo uma média de 600 atendimentos diários. O processo de testagem foi organizado em três etapas: 1) acolhimento; 2) coleta da amostra biológica e 3) entrega do resultado. A atuação do farmacêutico se deu nas etapas 2 e 3 onde, além do cumprimento da etapa em si, alguns serviços farmacêuticos foram prestados a exemplo da educação em saúde e da gestão da condição de saúde. Ainda na etapa de entrega do resultado, foi realizada a leitura do laudo junto ao cliente, bem como houveram esclarecimentos e orientações acerca o isolamento social e uso de máscara. Os casos positivos foram encaminhados para as unidades referências de síndrome gripal. Diante disso, pode-se concluir que a atuação do farmacêutico foi importante para a população devido ao cuidado prestado por meio dos serviços farmacêuticos de Educação em saúde e Gestão da condição de saúde.

Este foi realizado no Ambulatório de Oncologia do HGP em quatro diferentes etapas, sendo elas sensibilização da equipe, mapeamento do  processo de trabalho, diagnóstico do processo e desenvolvimento do plano de ação. As informações foram coletadas por meio de reuniões com a equipe composta por farmacêuticos, médicos, enfermeiros e recepcionistas. Foram utilizadas ferramentas da gestão da qualidade, que são Bizagi modeler,  Diagrama de Ishikawa e plano de ação 5W2H, para traçar um fluxo lógico de atendimento do paciente pela unidade ambulatorial e esquematizar os processos de trabalho, para assim poder apresentar uma solução para os problemas encontrados. A falta da esquematização do atendimento aos pacientes dentro do Ambulatório de Oncologia do HGP prejudica a gestão do estoque de medicamentos por não ser possível identificar falhas e duplicidade de atividades. Por outro lado, a melhoria desses processos de trabalho agrega ganhos de eficiência e, via de consequência, redução de custos relativos com potencial ampliação do acesso aos usuários do serviço. Algo extremamente importante em tempos de pandemia, que trouxe  ampliação dos gastos no seu enfrentamento.
Citizen Carbon Fund: Harmonized International Carbon Taxes and Transfers to Increase Treaty Size
Authors: Klis Anna A. , McGinty Matthew
Published: February 2022

A uniform carbon tax and Citizen Carbon Fund are proposed as a zero-sum system of transfers that can increase equilibrium participation and result in a positive carbon check for each citizen covered by the agreement. The carbon tax results in efficient abatement, generates tax revenue and finances transfers that increase equilibrium participation in a climate agreement. A single carbon price is easier to negotiate than many different abatement requirements, but mirrors the results of a cap-and-trade agreement. An example using the four largest carbon emitters illustrates the set of stable agreements, the transfers required for stability and the resulting carbon checks.

In order to improve the performance of engines fueled with diesel fuel or diesel-like e-fuels so as to realize greener transportation, the V-type and Y-type intersecting hole nozzles, in which each hole is formed by the coalescence of two or three subholes, have been designed. In this article, the multiphase flow inside and outside the nozzle was numerically investigated using a volume-of-fluid large eddy simulation (VOF-LES) method to clarify the effects of the nozzle structure on the cavitating flow and primary atomization characteristics. The calculation was carried out at an injection pressure of 150 MPa and a back pressure of 0.1 MPa. Numerical results showed that unlike the L-shape pressure distribution along a cylindrical hole, for intersecting type hole nozzles, the pressure showed a stepped shape drop along the holes due to the overall convergent hole structure, which restrained the inception of cavitation. Consequently, the global loss of the flow over an intersecting type hole nozzle was lower by 24–37% than those of a cylindrical hole nozzle. Additionally, the jets emerging from the intersecting hole nozzles showed 50% wider spreading angles and 27% smaller droplet sizes than those of the cylindrical hole nozzle. Furthermore, the jets emerging from a Y-type intersecting hole nozzle showed enhanced atomization, which was found to be due to the unstable air suction near the outlets of this type of nozzle hole.

Authors: Pisapan Phatrakit , Wongpanyo Watchara
Published: February 2022

This research was conducted on the ability of Power Line Communication (PLC) technology to communicate data for home energy management system through the traditional home electrical grids in Thailand. The study found that the Narrow-Band Power Line Communication (NB-PLC) is most suitable for smart home applications and safe for health of the residents. The results showed that the efficacy of PLC is mostly dependent on the service life time factor of the cables. The regression rate of signal level for the newest electric wire (1–15 years) is 83% lower than the oldest (30–45 years) and 47% lower than the middle life time (16–30 years). Also, the regression rate of signal level for the middle life time was 69% lower than the oldest wire. Whereby we could predict the signal level according to the changing length and service life time of electric cable. In this research, it was found that the carrier frequencies also are influence on the signal level of the power line communication. The signal level of KNX PL110 standard which used the frequency range 105 and 115 kHz is higher than the signal level of IDIS that used the frequency range 63.3 and 74.5 kHz and the regression of signal level of KNX PL110 standard is 68% lower than the IDIS standard. The experimental results also showed that baud rate “2400” is the best for power line communication because it generates more stable signal levels.

Published: February 2022

This investigation was aimed to assess and evaluate the effect of frying process with three different oils (corn, olive and margarine) on fatty acids and lipid classes’ composition of clam and their impact on the nutritional value and tissues quality. The results indicated that the contents of saturated, monounsaturated and polyunsaturated fatty acids varied significantly in fried clams and frying oil. Our data demonstrated that all lipid classes’ contents increased significantly after all frying processes. It was concluded that the frying process decreased the n-3/n-6 and DHA+EPA and increased the levels of atherogenic; thrombogenic indices. Additionally, these culinary processes promoted lipid peroxidation through the enhancement of TBARs, PV and FFA. These changes were more significant and intensive after frying with margarine and corn oils followed by virgin olive oil. These results suggest that clam fried with olive oil can be classified as highly nutritive in regard to its lipid content, major fatty acid profile; and nutritional value.
Evaluation of QZSS orbit and clock products for real-time positioning applications
Authors: Bramanto Brian , Gumilar Irwan
Published: February 2022

The Quasi-Zenith Satellite System (QZSS) is the recent Japanese satellite positioning system to enhance the positioning accuracy in Japan’s urban areas. Additionally, they provide precise orbit and clock corrections and can be obtained through their experimental signals (LEX), streaming access, and published site. Multi-GNSS Advanced Demonstration tool for Orbit and Clock Analysis (MADOCA) is one of the precise products offered in QZSS services that can be obtained on a global scale. In this study, we evaluated the performance of MADOCA orbit and clock corrections, particularly for real-time positioning applications using LEX signals. Based on the simulation, we predict that 16 countries in the East Asia and Oceania regions will gain the maximum benefit of the LEX signals. However, we stress that one may have difficulties decoding the LEX signals at regions where only one QZSS satellite is observed. During our sailing expedition at Sumatran Sea, we could only decode up to 37 % LEX signals for the observation period. It profoundly increased up to 95 % at Sulawesi Strait where at least three QZSS satellites with an elevation angle of, at its minimum, 40° were observed. The orbit and clock accuracy is estimated to be 5.2 cm and 0.6 ns with respect to International GNSS Service (IGS) final products. Our simulation of using the Real-Time Precise Point Positioning (RTPPP) method revealed that the accuracy of the corresponding positioning applications was less than one decimeter. Further, we compared the MADOCA products for RTPPP applications with Apex5 positioning solutions in static field observations. The positioning accuracy for MADOCA-RTPPP during the field observations was estimated to be centimeter to decimeter level and is slightly worse than Apex5 positioning solutions. Nevertheless, we highlight vast positioning applications using MADOCA-RTPPP, e. g., survey and mapping, smart agriculture, and offshore engineering navigation.

Objectives

The aim of this study was to recognize the efficacy and safety of curcumin ointment on patients with knee osteoarthritis (OA) compare to diclofenac as standard medication.

Methods

The topical effects of curcumin (10%) and diclofenac (1%) ointments were assessed through the visual analog scale (VAS) and Western Ontario and McMaster Universities Arthritis (WOMAC) index after three times a day administration for two weeks in 60 patients.

Results

Desirable effects compared to the pre-treatment period were observed after two weeks of continuous treatment. Based on our results, VAS and WOMAC index were altered after treatment significantly (p<0.0001).

Conclusions

Two-week use of curcumin ointment could ameliorate the pain, stiffness and function disability in patients with OA.
Variation determinants within massage therapists’ professional identity
Authors: Baskwill Amanda , Vanstone Meredith , Harnish Del , Dore Kelly
Published: February 2022

Objectives

Individuals have multiple, competing identities that vary in importance to the self. Professional identity is a way in which individuals attribute meaning to their contribution to society and is influenced by complex factors. Globally, the roles and responsibilities of massage therapists (MTs) vary, making it challenging to articulate a cohesive professional identity. This article describes the investigation into the variables which influenced response regarding MTs’ professional identity in Ontario, Canada.

Methods

An online questionnaire was distributed to active MTs with available email addresses in the public register of the College of Massage Therapists of Ontario. Chi-square tests of independence were used to compare dependent variables with independent variables. Significance was adjusted post hoc, using Bonferroni’s correction, to reduce the chance of a type I error occurring. The threshold for significance was adjusted from p≤0.05 to p≤0.01 as multiple analyses were conducted with a high response rate.

Results

The results provided insight into the variables associated with differences in responses. Variation was seen based on gender, primary practice setting, length in practice, additional education, additional roles within the profession, additional designation as a healthcare provider, and membership in the RMTAO (Registered Massage Therapists’ Association of Ontario).

Conclusions

While previous studies sought to describe the common and unifying features of MTs’ identity, these findings provide insight into variables that determine differences in responses. These findings are valuable for the development of future studies. They provide a priori assumptions regarding the inclusion of these demographic items that can inform decisions regarding enrollment of the sample and data analysis.

Objectives

Raudra rasa is an ayurvedic medicine explicitly prescribed for the treatment of arbuda (cancer), whereas hiraka bhasma has the potential to promote cancer healing properties. Together, these two medicines provide multifunction benefits. This paper analyses the functional groups of Raudra rasa modified with hiraka bhasma and compares it with the classically prepared raudra rasa. To identify the functional group, organic ligands, and active compounds present in samples of raudra rasa (CRR) and modified raudra rasa with hiraka bhasma (MRR) contributing to cancer alleviation by using Fourier transform infrared spectroscopy (FTIR) & LC-MS analysis.

Methods

Classical raudra rasa (CRR), its ingredients, shadguna kajjali (SK); decoction of Piper betel Linn. (PBD); Amaranthus spinosus Linn. (ASD); Boerhaavia diffusa Linn. (BDD); Piper longum Linn. (PLD); cow urine (GM), & similarly modified raudra rasa (MRR), its ingredients, hiraka bhasma (HB); shadguna rasasindura (SHR); water-soluble extract of Piper betel Linn. (PBE); Amaranthus spinosus Linn. (ASE); Boerhaavia diffusa Linn. (BDE); cow urine ark (GA); Piper Longum Linn. (PLE) were subjected to FTIR and LC-MS analysis.

Results

Among all 15 samples studied, maximum numbers of peaks (21) were seen in MRR indicating a greater number of functional groups. Further, in MRR, a maximum peak in the double bond region is suggestive of its higher stability compared to CRR. Both the compound is preliminarily a mixture of the number of functional groups like; fluoro, methyl, amino, hydroxy, nitro, methylamino, carbonyl, and iodo groups, having known anti-proliferative activities. By the FT-IR analysis, the biologically active compounds in aqueous and methanol extract of CRR & MRR were identified that have anti-cancerous compounds. In the present study, a total of 40 major compounds like alkaloids, amino acid, carboxylic acid, Flavonoids, Nucleoside, Nucleotide, phenylpropanoid, Sphingosine, stilbenoid, sugar, phosphate, terpenoids, vitamin from aqueous & methanol extract of CRR & MRR were identified by LC-MS.

Conclusions

This research paper highlights the presence of different functional groups and bioactive compounds known to have anti-cancer activities. Thus, this review suggests future recommendations for the design and development of improved anticancer drugs with higher efficacy.
