Published: May 2024

Background

Periprosthetic joint infection (PJI) is one of the most serious and debilitating complications that can occur after total joint arthroplasty. Therefore, early diagnosis and appropriate treatment are important for a good prognosis. Recently, molecular diagnostic methods have been widely used to detect the causative microorganisms of PJI sensitively and rapidly. The Multiplex Loop-Mediated Isothermal Amplification (LAMP) method eliminates the complex temperature cycling and delays caused by temperature transitions seen in polymerase chain reaction (PCR) methods, making it faster and easier to perform compared to PCR-based assays. Therefore, this study developed a multiplex LAMP assay for diagnosing bacterial PJI using LAMP technology and evaluated its analytical and clinical performance.

Methods

We developed a multiplex LAMP assay for the detection of five bacteria: Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae, Pseudomonas aeruginosa, and Escherichia coli, frequently observed to be the causative agents of PJI. The method of analytical sensitivity and cross-reactivity were determined by spiking standard strains into the joint synovial fluid. The analytical sensitivity of the multiplex LAMP assay was compared with that of a quantitative real-time PCR (qPCR) assay. Clinical performance was evaluated using 20 joint synovial fluid samples collected from patients suspected of having bacterial PJI.

Results

The analytical sensitivity of the gram-positive bacterial multiplex LAMP assay and qPCR were 105/104 CFU/mL, 103/103 CFU/mL, and 105/104 CFU/mL against S. agalactiae, S. epidermidis, and S. aureus, respectively. For P. aeruginosa and E. coli, the analytical sensitivity of the multiplex LAMP and qPCR assays were 105/104 and 106/104 CFU/mL, respectively. The multiplex LAMP assay detects target bacteria without cross-reacting with other bacteria, and exhibited 100% sensitivity and specificity in clinical performance evaluation.

Conclusions

This multiplex LAMP assay can rapidly detect five high-prevalence bacterial species causing bacterial PJI, with excellent sensitivity and specificity, in less than 1 h, and it may be useful for the early diagnosis of PJI.
Brood indicators are an early warning signal of honey bee colony loss—a simulation-based study
Authors: Groeneveld Jürgen , Odemer Richard , Requier Fabrice
Published: May 2024

Honey bees (Apis mellifera) are exposed to multiple stressors such as pesticides, lack of forage, and diseases. It is therefore a long-standing aim to develop robust and meaningful indicators of bee vitality to assist beekeepers While established indicators often focus on expected colony winter mortality based on adult bee abundance and honey reserves at the beginning of the winter, it would be useful to have indicators that allow detection of stress effects earlier in the year to allow for adaptive management. We used the established honey bee simulation model BEEHAVE to explore the potential of different indicators such as population size, number of capped brood cells, flight activity, abundance of Varroa mites, honey stores and a brood-bee ratio. We implemented two types of stressors in our simulations: 1) parasite pressure, i.e. sub-optimal Varroa treatment by the beekeeper (hereafter referred as Biotic stress) and 2) temporal forage gaps in spring and autumn (hereafter referred as Environmental stress). Neither stressor type could be detected by bee abundance or honey reserves at the end of the first year. However, all response variables used in this study did reveal early warning signals during the course of the year. The most reliable and useful measures seem to be related to brood and the abundance of Varroa mites at the end of the year. However, while in the model we have full access to time series of variables from stressed and unstressed colonies, knowledge of these variables in the field is challenging. We discuss how our findings can nevertheless be used to develop practical early warning indicators. As a next step in the interactive development of such indicators we suggest empirical studies on the importance of the number of capped brood cells at certain times of the year on bee population vitality.
Intelligent fault detection strategy for knowledge entities in fault semantic networks of distribution network based on siamese networks
Authors: Sun Xinjie , Qin Tao , Tong Lingyun , Zhang Haoliang , Xu Weihan
Published: May 2024

The advent of smart grid technologies has brought about a paradigm shift in the management and operation of distribution networks, allowing for intricate system information to be encapsulated within semantic network models. These models, while robust, are not immune to faults within their knowledge entities, which can arise from a myriad of issues, potentially leading to verification failures and operational disruptions. Addressing this critical vulnerability, our research delves into the development of a novel fault detection methodology specifically tailored for the knowledge entity variables of semantic networks in distribution networks. In our approach, we first construct a state space equation that models the behavior of knowledge entity variables in the presence of faults. This foundational framework enables us to apply an unknown input observer strategy to effectively detect anomalies within the system. To bolster the fault identification process, we introduce the innovative use of a siamese network, a neural network architecture which is proficient in differentiating between similar datasets. Through simulation scenarios, we demonstrate the efficacy of our proposed fault detection method.
An insight into the causal relationship between sarcopenia-related traits and venous thromboembolism: A mendelian randomization study
Authors: Du Xinchao , Yao Zhiwei , Wang Dongwei , Dong Xinwei , Bai Juncai , Gu Yingchun , Yu Yaohua , Zhang Weifeng , Qi Qingxia , Gu Shengyuan
Published: May 2024

Background

As a geriatric syndrome, sarcopenia has a high prevalence in the old population and represents an impaired state of health with adverse health outcomes. A strong clinical interest in its relationship with venous thromboembolism (VTE), which is a complex trait disease with a heterogeneous annual incidence rate in different countries, has emerged. The relationship between sarcopenia and venous thromboembolism has been reported in observational studies but the causality from sarcopenia to VTE remained unclarified. We aimed to assess the causal effect of sarcopenia on the risk of VTE with the two-sample Mendelian randomization (MR) method.

Methods

Two sets of single-nucleotide polymorphisms (SNPs), derived from two published genome-wide association study (GWAS) meta-analyses and genetically indexing muscle weakness and lean muscle mass separately, were pooled into inverse variance weighted (IVW), weighted median and MR-Egger analyses.

Results

No evidence was found for the causal effect of genetically predicted muscle weakness (IVW: OR = 0.90, 95% CI = 0.76–1.06, p = 0.217), whole body lean mass (IVW: OR = 1.01, 95% CI = 0.87–1.17, p = 0.881) and appendicular lean mass (IVW: OR = 1.13, 95% CI = 0.82–1.57, p = 0.445) on the risk of VTE. However, both genetically predicted whole-body lean mass and appendicular lean mass can causally influence diabetes mellitus (IVW of whole-body lean mass: OR = 0.87, 95% CI = 0.78–0.96, p = 0.008; IVW of appendicular lean mass: OR = 0.71, 95% CI = 0.54–0.94, p = 0.014) and hypertension (IVW of whole-body lean mass: OR = 0.92, 95% CI = 0.87–0.98, p = 0.007; IVW of appendicular lean mass: OR = 0.84, 95% CI = 0.73–0.96, p = 0.013).

Conclusions

Genetically predicted sarcopenia does not causally influence VTE directly, but it might still have an indirect effect on VTE incidence via diabetes mellitus and hypertension.
Songs tell a story: The Arc of narrative for music
Authors: Alberhasky Max , Durkee Patrick K.
Published: May 2024

Research suggests that a core lexical structure characterized by words that define plot staging, plot progression, and cognitive tension underlies written narratives. Here, we investigate the extent to which song lyrics follow this underlying narrative structure. Using a text analytic approach and two publicly available datasets of song lyrics including a larger dataset (N = 12,280) and a smaller dataset of greatest hits (N = 2,823), we find that music lyrics tend to exhibit a core Arc of Narrative structure: setting the stage at the beginning, progressing the plot steadily until the end of the song, and peaking in cognitive tension in the middle. We also observe differences in narrative structure based on musical genre, suggesting different genres set the scene in greater detail (Country, Rap) or progress the plot faster and have a higher rate of internal conflict (Pop). These findings add to the evidence that storytelling exhibits predictable language patterns and that storytelling is evident in music lyrics.
How healthcare providers and the right information may play a critical role in quitting success among smokers interested in using e-cigarettes for quitting: Results from a survey of U.S adults
Authors: Sharma Akshika , King Jaelen , Krishnan-Sarin Suchitra , O’Malley Stephanie S. , Morean Meghan , Bold Krysten
Published: May 2024

Introduction

Promoting smoking cessation is a global public health priority. E-cigarettes are increasingly being used by individuals to try quitting smoking. Identifying sources and types of information available to adults who are trying to quit, and the impact of this information during a quit attempt, is critical to augment the potential public health benefit of e-cigarettes for reducing cigarette smoking.

Methods

US adults (N = 857) who reported using e-cigarettes in a recent smoking cessation attempt completed an anonymous, cross sectional, online survey. We examined sources of information and type of information received when using e-cigarettes to quit smoking and their associations with the duration of abstinence achieved.

Results

The two most commonly reported information sources were friends (43.9%) and the internet (35.2%), while 14.0% received information from a healthcare provider. People received information on type of device (48.5%), flavor (46.3%), and nicotine concentration (43.6%). More people received information about gradually switching from smoking to vaping (46.7%) than abruptly switching (30.2%). Obtaining information from healthcare providers (β (SE) = 0.16 (0.08), p = 0.04), getting information about abruptly switching to e-cigarettes (β (SE) = 0.14 (0.06), p = 0.01) and what nicotine concentrations to use (β (SE) = 0.18 (0.05), p = 0.03) were associated with longer quit durations.

Conclusions

Amidst the growing popularity of e-cigarettes use for quitting smoking, our results highlight common sources of information and types of information received by individuals. Few people received information from healthcare providers indicating a gap in cessation support that can be filled. Providing information about immediate switching to e-cigarettes and nicotine concentrations to use may help in increasing quit rates and duration.
Development and performance evaluation of a solenoid valve assisted low-cost ventilator on gas exchange and respiratory mechanics in a porcine model
Authors: Shyu Daniel , Bliss Peter , Adams Alexander , Cho Roy Joseph
Published: May 2024

Introduction

During the COVID-19 pandemic, ventilator shortages necessitated the development of new, low-cost ventilator designs. The fundamental requirements of a ventilator include precise gas delivery, rapid adjustments, durability, and user-friendliness, often achieved through solenoid valves. However, few solenoid-valve assisted low-cost ventilator (LCV) designs have been published, and gas exchange evaluation during LCV testing is lacking. This study describes the development and performance evaluation of a solenoid-valve assisted low-cost ventilator (SV-LCV) in vitro and in vivo, focusing on gas exchange and respiratory mechanics.

Methods

The SV-LCV, a fully open ventilator device, was developed with comprehensive hardware and design documentation, utilizing solenoid valves for gas delivery regulation. Lung simulator testing calibrated tidal volumes at specified inspiratory and expiratory times, followed by in vivo testing in a porcine model to compare SV-LCV performance with a conventional ventilator.

Results

The SV-LCV closely matched the control ventilator’s respiratory profile and gas exchange across all test cycles. Lung simulator testing revealed direct effects of compliance and resistance changes on peak pressures and tidal volumes, with no significant changes in respiratory rate. In vivo testing demonstrated comparable gas exchange parameters between SV-LCV and conventional ventilator across all cycles. Specifically, in cycle 1, the SV-LCV showed arterial blood gas (ABG) results of pH 7.54, PCO2 34.5 mmHg, and PO2 91.7 mmHg, compared to the control ventilator’s ABG of pH 7.53, PCO2 37.1 mmHg, and PO2 134 mmHg. Cycle 2 exhibited ABG results of pH 7.53, PCO2 33.6 mmHg, and PO2 84.3 mmHg for SV-LCV, and pH 7.5, PCO2 34.2 mmHg, and PO2 93.5 mmHg for the control ventilator. Similarly, cycle 3 showed ABG results of pH 7.53, PCO2 32.1 mmHg, and PO2 127 mmHg for SV-LCV, and pH 7.5, PCO2 35.5 mmHg, and PO2 91.3 mmHg for the control ventilator.

Conclusion

The SV-LCV provides similar gas exchange and respiratory mechanic profiles compared to a conventional ventilator. With a streamlined design and performance akin to commercially available ventilators, the SV-LCV presents a viable, readily available, and reliable short-term solution for overcoming ventilator supply shortages during crises.
Analysis of a new negevirus-like sequence from Bemisia tabaci unveils a potential new taxon linking nelorpi- and centiviruses

Published: May 2024

This study presents the complete genome sequence of a novel nege-like virus identified in whiteflies (Bemisia tabaci MEAM1), provisionally designated as whitefly negevirus 1 (WfNgV1). The virus possesses a single-stranded RNA genome comprising 11,848 nucleotides, organized into four open reading frames (ORFs). These ORFs encode the putative RNA-dependent-RNA-polymerase (RdRp, ORF 1), a glycoprotein (ORF 2), a structural protein with homology to those in the SP24 family, (ORF 3), and a protein of unknown function (ORF 4). Phylogenetic analysis focusing on RdRp and SP24 amino acid sequences revealed a close relationship between WfNgV1 and Bemisia tabaci negevirus 1, a negevirus sequence recently discovered in whiteflies from Israel. Both viruses form a clade sharing a most recent common ancestor with the proposed nelorpivirus and centivirus taxa. The putative glycoprotein from ORF 2 and SP24 (ORF 3) of WfNgV1 exhibit the characteristic topologies previously reported for negevirus counterparts. This marks the first reported negevirus-like sequence from whiteflies in the Americas.

Note for the Fermat Equation
Authors: Vega Frank
Published: May 2024

The Fermat's Last Theorem was first stated as a theorem by Pierre de Fermat around 1637 in the margin of a copy of Arithmetica. Fermat added that he had a proof that was too large to fit in the margin. He claimed to have discovered a proof for the equation $a^{n} + b^{n} = c^{n}$ having no solutions in positive integers for $n$ greater than $2$. However, he didn't provide the details of his proof. This theorem remained unproven for centuries until Andrew Wiles published a proof in 1994. Wiles proof is very far for being closed to the Fermat's claimed theorem due to its long extension, complexity and tools that were only available during the 20th century. This work could be closer to the Fermat's claimed proof.

Authors: Rahman Sarli , Suyono Suyono , Setyawan Onny , Irman Mimelientesa
Published: May 2024

This study focuses on factors that can improve SME business performance, from a theoretical market-base view perspective, with a market orientation construct, and from a resource-base view theory, specifically from innovation resources, with a market orientation construct. In addition, this study also aimed to look at the factors that can hinder SMEs from carrying out innovation practices, and how these barriers affected the innovation practices and performance of SMEs. Through an online survey, collected of 352 answered of respondents analyze using Structural Equation Methods. From the results of the AMOS SEM analysis, it was found that market orientation directly affects the performance of SMEs without finding the mediating role of innovation practices. However, innovation practices can mediate the effect of innovation barriers on SME performance in a negative direction. The result of this study has theoretical and practical implications that will also be discussed.

River debris in Jakarta is generated in several locations by conventional transportation. Waste transportation with traditional models is usually not time-efficient, primarily when river debris is generated every time. Transport systems that can be used for river debris include compactor systems, pre-compactor systems, and baller systems. This research uses literature study and secondary data in determining alternatives. Meanwhile, the alternative selection was carried out using the Multi-Criteria Decision Making (MCDM) method. This study uses four criteria for selecting alternatives: initial capital, type of transport container, operation and maintenance, and processing capability. The utility value of waste transportation with compaction and pre-compacting systems does not significantly have utility values of 0.722 and 0.833, respectively. At the same time, the baller system has a utility value of 0.222. This shows that the compacted system is more suitable to be applied to SPA river debris in Jakarta. The presence of a pr-compactor can also reduce the water content in-river debris.

Endogenous Financial Friction and Growth
Authors: Jeong Minhyeon
Published: May 2024

Financial frictions have been considered a crucial factor in explaining growth disparities across countries. These frictions are typically viewed as an exogenous constraint on borrowing capacity that is assumed to be invariant to economic conditions, such as the level of GDP and business cycle fluctuations. However, assuming the exogenous constraint on borrowing often leads to unrealistic dynamics in macroeconomic variables, such as constant investment-to-GDP and loan-to-value ratios. Motivated by these limitations, we develop a growth model in which the severity of the borrowing constraint is endogenously determined. The borrowing constraint adversely affects growth and amplifies the negative effect of volatility on growth. However, these growth effects gradually disappear as the economy continues to grow, because debtors become more willing to honor their debts along with economic growth, resulting in an endogenous relaxation of the borrowing constraint.
Population Dependent Two-Sex Branching Process with Random Mating and Overlapping Generations
Authors: Molina Manuel , Mota Manuel
Published: May 2024

This research focuses on stochastic modeling of the evolution over time of biological populations through branching processes. We introduce a new class of discrete time two-sex branching processes with random mating and overlapping generations. Mating and reproduction are considered to be influenced by the numbers of females and males existing in the population. This evolution over time with generational overlap is a novel research in two-sex branching process literature. We study general probabilistic properties and establish some limiting results of biological interest.

Published: May 2024

Recognizing the flow behaviours across a Riga plate can reveal information about the aerodynamic efficiency of aircraft, heat propagation, vehicles, and other structures. These data are critical for optimizing design and lowering drag. Therefore, the purpose of the current analysis is to examine the energy and mass transfer across the mixed convective nanofluid flows over an extending Riga plate. The fluid flow is deliberated under the influences of viscous dissipation, exponential heat source/sink, activation energy, and thermal radiation. The Buongiorno’s concept is utilized for the thermophoretic effect and Brownian motion along with the convective conditions. The modelled are simplified into the lowest order by using similarity transformation. The obtained set of non-dimensional ordinary differential equations is then numerically solved through the parametric continuation method. For accuracy and validation of the outcomes, the results are compared to the existing studies. From the graphical analysis, it can be observed that the fluid velocity boosts with the rising values of the divider thickness parameter. The fluid temperature also improves with the effect of Biot number, Eckert number, and heat source factor. Furthermore, the effect of heat source sink factor drops the fluid temperature.
‚Versicherungsfremde Leistungen‘ in der gesetzlichen Krankenversicherung: Kritik eines gesundheitspolitischen Leitbegriffs
Authors: Simon Michael
Published: May 2024

Der Beitrag befasst sich mit der Diskussion über ‚versicherungsfremde Leistungen‘ in der gesetzlichen Krankenversicherung (GKV). Es wird ein Überblick gegeben über die Entwicklung der Diskussion seit den 1950er Jahren und darüber, welche Elemente und Leistungen der GKV bisher als ‚versicherungsfremd‘ bezeichnet wurden. Bei den als ‚versicherungsfremd‘ bezeichneten Elementen handelt es sich um solche, die konstitutiv für die GKV sind, und die als ‚versicherungsfremd‘ bezeichneten Leistungen sind Bestandteil des Leistungskataloges der GKV. Die Verwendung des Begriffs ‚versicherungsfremd‘ impliziert folglich die Forderung nach Beseitigung dieser Elemente und Ausgliederung dieser Leistungen aus der GKV. Es wird gezeigt, dass der Verwendung des Begriffs letztlich das Geschäftsmodell der privaten Krankenversicherung als Maßstab zugrunde liegt. Die Verwendung des Begriffs impliziert somit die Forderung nach Angleichung der GKV an das Geschäftsmodell der PKV.
Rapid Learning and Long-term Memory in the Speech-to-song Illusion
Authors: Kubit Benjamin M. , Deng Christine , Tierney Adam , Margulis Elizabeth H.
Published: May 2024

The speech-to-song illusion is a perceptual transformation in which a spoken phrase initially heard as speech begins to sound like song across repetitions. In two experiments, we tested whether phrase-specific learning and memory processes engaged by repetition contribute to the illusion. In Experiment 1, participants heard 16 phrases across two conditions. In both conditions, participants heard eight repetitions of each phrase and rated their experience after each repetition using a 10-point scale from “sounds like speech” to “sounds like song.” The conditions differed in whether the repetitions were heard consecutively or interleaved such that participants were exposed to other phrases between each repetition. The illusion was strongest when exposures to phrases happened consecutively, but phrases were still rated as more song-like after interleaved exposures. In Experiment 2, participants heard eight consecutive repetitions of each of eight phrases. Seven days later, participants were exposed to eight consecutive repetitions of the eight phrases heard previously as well as eight novel phrases. The illusion was preserved across a delay of one week: familiar phrases were rated as more song-like in session two than novel phrases. The results provide evidence for the role of rapid phrase-specific learning and long-term memory in the speech-to-song illusion.
Artificial Intelligence and Musicking
Authors: Berkowitz Adam Eric
Published: May 2024

Artificial intelligence (AI) deployed for customer relationship management (CRM), digital rights management (DRM), content recommendation, and content generation challenge longstanding truths about listening to and making music. CRM uses music to surveil audiences, removes decision-making responsibilities from consumers, and alters relationships among listeners, artists, and music. DRM overprotects copyrighted content by subverting Fair Use Doctrine and privatizing the Public Domain thereby restricting human creativity. Generative AI, often trained on music misappropriated by developers, renders novel music that seemingly represents neither the artistry present in the training data nor the handiwork of the AI’s user. AI music, as such, appears to be produced through AI cognition, resulting in what some have called “machine folk” and contributing to a “culture in code.” A philosophical analysis of these relationships is required to fully understand how AI impacts music, artists, and audiences. Using metasynthesis and grounded theory, this study considers physical reductionism, metaphysical nihilism, existentialism, and modernity to describe the quiddity of AI’s role in the music ecosystem. Concluding thoughts call researchers and educators to act on philosophical and ethical discussions of AI and promote continued research, public education, and democratic/laymen intervention to ensure ethical outcomes in the AI music space.

Este artículo de investigación aborda la importancia de regular la figura jurídica de los servicios intragrupo en el ordenamiento jurídico nicaragüense. Se contextualiza la práctica de provisión de estos servicios y se expresa la necesidad de una pronta regulación, analizando los antecedentes de la Ley de Concertación Tributaria. Además, se plantean propuestas para incorporar esta regulación en el ordenamiento jurídico tributario del país. En este sentido, se busca incrementar la certidumbre jurídica de las empresas que operan en Nicaragua, reducir el riesgo y la probabilidad de obtener ajustes fiscales y disminuir la necesidad de que la autoridad tributaria nicaragüense dedique sus escasos recursos a auditar este tipo de transacciones. Para desarrollar estos puntos, se hace referencia a las directrices de la OCDE aplicables en materia de precios de transferencia a empresas multinacionales y administraciones tributarias, así como a la definición y determinación del precio de plena competencia.

バイオクロッギング（bioclogging）は、土壌の間隙に微生物のバイオマス（微生物そのものと微生物が分泌する細胞外高分子物質のような物質）が目詰まりをする現象である。微生物のバイオマスは土壌間隙の水の通り道をブロックして、土壌中に一定の厚さの難透水層を形成し、水の浸透速度を著しく低下させる。生物的目詰まり（biological clogging）とも言う。 バイオクロッギングは、水が浸透する様々な現場で観察される。たとえば、ため池、浸透トレンチ、灌漑水路、下水処理場、人工湿地、廃棄物処分場における遮水ライナー、川床や土壌のような自然環境などである。また、透過反応壁 (PRB) や微生物利用石油増進回収法 (MEOR) などにおいて、帯水層における地下水の流れにも影響を及ぼす。適度な水の浸透速度を保つことが必要とされるような現場では、バイオクロッギングが問題となり、定期的に水を抜くなどの対策が取られることがある。一方で、たとえば、難透水層を作って浸透速度を低下させたり、地盤工学的性質を改善させたりするなど、バイオクロッギングが有効に活用されることもある。

Correlación entre las soluciones extractoras KCl-Olsen modificado y Mehlich 3, usadas en los laboratorios de suelos de Costa Rica
Authors: Bertsch Floria , Bejarano José Antonio , Corrales Marco
Published: May 2024

Se discute la correlación encontrada entre las 2 soluciones de uso más común en los Laboratorios de Suelos de Costa Rica, para las determinaciones de Ca, Mg, K, Zn y P en los análisis de suelos. Dada la coexistencia de metodologías de extracción, es de gran relevancia poner a disposición de los usuarios información que permita una interpretación adecuada de los resultados de los análisis. Con los datos de intercambio entre laboratorios, llevado a cabo a nivel nacional, se establecieron relaciones entre la solución KCl-Olsen Modificado y Mehlich 3. Para todos los elementos determinados, con excepción del P, la asociación entre ambas soluciones es muy clara y definida. Ambas soluciones extraen lo mismo de Ca y Mg, Mehlich 3 extrae 1,5 veces más K que Olsen Modificado; en el caso de Zn, en suelos ricos en Ca ( > 10 cmol(+) l-1), Mehlich 3 extrae más Zn, por lo que hay que subir el nivel crítico a 3,5 mg l-1; mientras que en suelos bajos en Ca ( < 10 cmol(+) l-1) Mehlich 3 extrae menos Zn que Olsen Modificado, por lo tanto hay que bajar el nivel crítico a 2,5 mg l-1. Para P la asociación no es clara en absoluto.
Transformación genética de Echinacea purpurea y E. angustifolia mediante Agrobacterium rhizogenes
Authors: Loaiza Jorge , Valverde Roberto
Published: May 2024

Secciones de tallos de vitroplántulas de Echinacea purpurea y E. angustifolia fueron inoculadas con Agrobacterium rhizogenes cepa SV3101, con la finalidad de obtener plántulas transformadas. Se evaluó el efecto de la acetosiringona en combinación con floroglucinol sobre la transformación. El proceso de transformación aumentó proporcional y significativamente conforme se incrementó las concentraciones de ambos productos; llegándose a obtener un 100% de trasformación cuando se usó 200 μM de acetosiringona en combinación con 50 mg l –1 de floroglucinol. La eliminación de la bacteria se logró con 6 ml l-1 del Plant Preservative Mixture (PPM). También, se logró el cultivo in vitro de sólo raíces trasformadas, las cuales incrementaron su peso seco 11 veces en un periodo de 24 días de cultivo, momento en el cual se hace necesario iniciar un nuevo cultivo.
Variables físicas, químicas y biológicas del suelo sobre las poblaciones de colémbolos en Costa Rica
Authors: Guillén Cesar , Soto Adames Felipe , Springer Monika
Published: May 2024

Se ha discutido que las variables físicas, químicas y biológicas del suelo influyen sobre las poblaciones de colémbolos; sin embargo, la información acerca de la interacción de estas variables, en conjunto, con relación a la diversidad y abundancia de colémbolos, es escasa. En el presente estudio se determinó la relación entre estas variables y la diversidad y abundancia de colémbolos en los suelos de un bosque primario, un bosque secundario y un cafetal en el Parque Nacional Tapantí. El bosque primario presentó los contenidos más altos de materia orgánica y biomasa microbiana, contrario a lo sucedido con la resistencia a la penetración y el pH. Los resultados mostraron una clara asociación entre estas variables y algunas especies de colémbolos, lo cual indica que los cambios en la estructura de las comunidades de colémbolos, por efecto de los cambios en las variables físicas, químicas y biológicas del suelo, pueden ser utilizados como un bioindicador de calidad del suelo y de manejo de los ecosistemas.

Se estudió los niveles críticos de Ca, Mg, K, P, S, Cu, Zn y Mn en Ultisoles, Inceptisoles, Vertisoles y Andisoles de Costa Rica, con la solución extractora Mehlich 3. Los niveles críticos en los Ultisoles para Ca, Mg y K fueron 4,0, 0,8 y 0,2 cmol(+) l-1, respectivamente, y para P, S, Cu, Mn y Zn 3,0, 36,0, 0,4, 4,0 y 1,5 mg l-1, respectivamente. En los Inceptisoles se encontró 3,1, 1,1 y 0,2 cmol(+) l-1 para el Ca, Mg y K, y 6,0, 32,0, 0,4, 4,0 y 1,7 mg l-1 para P, S, Cu, Mn y Zn. En los Vertisoles los valores correspondieron a 27,0, 13,0 y 0,27 cmol(+) l-1 para Ca, Mg y K, y 13,0, 32,0, 0,4, 4,0 y 3,0 mg l-1 para P, S, Cu, Mn y Zn. En los Andisoles se encontraron valores para Ca, Mg y K de 5,0, 0,75 y 0,22 cmol(+) l-1, y para P, S, Cu, Mn y Zn de 16,0, 31,0, 0,4, 4,0 y 2,5 mg l-1. Cuando se analizaron todos los suelos en conjunto se obtuvo niveles críticos de 5,0, 0,7 y 0,17 cmol(+) l-1 para Ca, Mg y K, y de 10,0, 31,0, 0,4, 4,0 y 2,0 mg l-1 para P, S, Cu, Mn y Zn.

Authors: WingChing-Jones Rodolfo , Rojas-Bourrillón Augusto
Published: May 2024

El objetivo de este trabajo fue determinar el efecto de la fuente y cantidad de nitrógeno (N) aplicado sobre las fracciones proteicas del sorgo Negro (Sorghum almun) cosechado a 54 días con cobertura permanente de maní forrajero (Arachis pintoi CIAT 18744). Para la fracción A se obtuvo de 5,76 a 9,14 (% PC), en la fracción B1 4,03-6,09, la fracción B2 23,61-28,24; la fracción B3 fue la de mayor concentración en el sorgo con 40,66-43,91, y la fracción C 18,48-18,96. El número de corte fue significativo para todas las fracciones analizadas, y solo para la fracción B2 el nivel de N aplicado al suelo fue significativo, causando la fertilización un incremento en esta fracción. Con relación a los contenidos de la proteína soluble (10,38-14%), proteína insoluble aprovechable (67,52- 70,65%) y proteína indigerible (18,48-18,96%) de la PC total del sorgo, este forraje presenta un comportamiento insoluble aprovechable, el cual podría limitar el crecimiento microbial en los rumiantes, en sistemas de alimentación como única fuente de alimento.
Síntesis histórica de la política de importación de banano de la Unión Europea

Síntesis histórica de la política de importación de banano de la Unión Europea. Este artículo resume los principales eventos en el conflicto entre la Unión Europea, los países productores de banano de África, el Caribe y el Pacífico, los productores latinoamericanos, y Estados Unidos, relacionados con la importación de banano en la Unión Europea. Se discute el debate histórico acerca de estas políticas entre las partes interesadas, debate que ha llegado a conocerse como "la guerra del banano". Describe eventos recientes relacionados con el proceso de transición de un mercado altamente protegido a un sistema de importación de tarifa única, el cual podría suavizar el conflicto pero no terminar con esta "guerra". El artículo está dividido en 7 partes: 1) descripción de la política de importación de banano de la Unión Europea antes de implementar la Política Comunitaria; 2) descripción de la Política Comunitaria de Importación de Banano en 1993; 3) discusión de los eventos que se originaron después de la aprobación del régimen de importación de 1993; 4) descripción de la perspectiva de la Unión Europea sobre la llamada guerra del banano; 5) convenio entre los Estados Unidos y la Unión Europea; 6) algunos resultados de investigaciones relacionadas con el nuevo sistema de importación y 7) conclusión.
¿Qué son plagas vertebradas?
Authors: Monge Javier
Published: May 2024

Se ofrece un panorama de la problemática con especies vertebradas plaga. Se define plaga vertebrada y se contrasta con el concepto de condición de plaga, al asumirse que ninguna especie vertebrada es plaga de manera permanente, sino que una determinada población puede adquirir esa condición en un momento y lugar específicos. Se hace referencia a las causas por las cuales una especie vertebrada puede convertirse en plaga, y se analiza la influencia del ser humano para que eso suceda. Finalmente se presenta una lista de daños que pueden ocasionar especies de aves, mamíferos, reptiles, anfibios y peces; daños relacionados con consumo o destrucción en áreas de producción; consumo o contaminación de alimentos almacenados; daños a infraestructura y equipos; transmisión de enfermedades o provocar la muerte a personas o animales domésticos; así como el impacto que pueden provocar al ambiente.
