“Nada puede dar una idea de ella sino es la vista”
Authors: Ramírez Hugo Rueda
Published: April 2024

Early on and after it reached its political independence, the elites in charge of the Republic of Chile made various attempts to create a museum for the country, which finally became a reality in 1841 under the title “Museo Nacional” (National Museum). This article examines the movements in the very notion of museum that circulated both among those elites and among those who undertook the task of bringing the project to fruition, identifying different shifts in its use and meaning. In a genealogical journey through the history of the Museo Nacional de Chile during the nineteenth century, this article posits that its definition was plastic in nature, which allowed it to be used for different purposes. During the first half of the century, this plasticity enabled the hierarchization of its properties, relegating the exhibition of collections to a secondary role. During the second half of the century, however, Rudolph Philippi, its director, would lead a modernization process that would attempt to inscribe the institution under his charge in the canons of the modern Western museum. In this process, the visual consumption of collections would become intrinsic to the notion of the museum. Its “optical” nature and the importance of the visual in the ways of experiencing it would demonstrate, as I postulate here, a relationship between the museum, observational practices, and national identity. As Philippi affirmed, nothing but sight could give a person an idea of the collection of “Chilean nature.”
Chicano Art and the Mass Media
Authors: Harris Ana Pozzi
Published: April 2024

This essay explores three paintings by Mel Casas dating to 1967. I argue that these paintings communicate the artist’s critical consciousness about the social disadvantages of Mexican Americans, both historically and at the crucial period of change that led to the formation of Chicano groups in San Antonio, Texas. Casas incorporates skin tones in his painted characters, which prompts a racialized interpretation. The analysis is grounded in the dualistic picture space represented in Casas’s remarkable series, the Humanscapes, where the artist both critiqued and incorporated mass media and advertising images. To construct an interpretative context for these works, I explore sources extracted from San Antonio newspapers, tracing debates about the changing racialization of Mexican Americans and about the formation of combative political groups in this city where Casas lived and worked. The three paintings, then, engage with a politicized context and with the artist’s personal experiences, establishing a continuous narrative with his best-known Chicano-period works, such as Brownies of the Southwest.

La transformación de los espacios residuales en lugares públicos de calidad: debajo de las líneas del Metro de Medellín
Authors: Bullaro Luca , Narváez Cárdenas Daniel Leandro
Published: April 2024

El artículo presenta resultados de la investigación “Nuevos enfoques” – desarrollada por el grupo de investigación Transepto, de la Universidad Nacional de Colombia, sede Medellín- del cual forma parte el trabajo de grado realizado por el arquitecto Daniel Narváez y es una reflexión sobre la posible y urgente transformación ecológica de los espacios residuales en nuestras ciudades: específicamente aquellos espacios vinculados a las grandes obras de infraestructura vial como los viaductos, los cuales en la mayoría de los casos se diseñan y construyen sin tener en cuenta su contexto inmediato, descuidando, por ejemplo, el espacio público que los rodea, convirtiéndose en lugares oscuros con presencia de basura y delincuencia, generando rechazo por parte de los habitantes del sector y la ciudad. Así pues, dentro de la investigación se identificaron y analizaron varios tipos de problemáticas relativas a estas franjas urbanas y se definieron unas aproximaciones iniciales con el fin de generar unas respuestas proyectuales que permitieran aprovechar estos lugares en función de la regeneración del espacio público, de la redefinición del paisaje natural y de los programas funcionales que puedan albergar.

Published: April 2024

Background: This pilot study explores the impact of quantitative flow ratio (QFR) guidance on decision-making for angioplasty and post-intervention procedures in stable coronary artery disease. Aim: The primary aim was to evaluate the vessel-oriented composite endpoint (VOCE) at 6 months, encompassing cardiac death, vessel-related MI and ischaemia-driven target vessel revascularisation. Secondary objectives included assessing individual components of VOCE and the influence that the QFR had on decision-making before and after interventions. Methods: The pilot study was conducted from 1 January to 31 July 2023 and included all angiogram patients. Cardiologists used QFR readings for decision-making, with QFR >0.80 indicating non-significance and <0.80 denoting significant stenosis, prompting angioplasty. The lesions were re-evaluated post-angioplasty and QFR >0.90 indicated that no further intervention was necessary. Results: A total of 770 subjects were screened. Most of the patients in the post-percutaneous coronary intervention (PCI) without QFR group were Malaysian (36.1%), while there were more Chinese patients in the PCI with QFR group (49.2%). Hypertension was the primary risk factor for both groups (79.5% and 73%, respectively). Decision changes were more common in pre-intervention assessments (39%), with 34% of these opted not to proceed whereas 66% agreed to proceed. Post-PCI decision changes were less common (22%); 19% of these opted for further intervention and 81% accepted the angiographic results before the QFR reading. VOCE at 6-month follow-up showed one cardiac death in the PCI without QFR group and none in the PCI with QFR group (p=0.316). Conclusion: QFR readings demonstrated significant value in guiding pre-PCI decisions. This study underscores the potential for enhanced decision-making and improved patient outcomes by using QFR-guided interventions.

Published: April 2024

The purpose of this report is to preset the changes that are being undertaken in the revenue models by companies in response to the conditions formed by VUCA environment. Depending on product variety, used distribution channels, pricing policy, and the speed of conversion of resources and costs into income (receipt), different revenue models are determined. Key concepts which are referred here directly to the revenue models are segmentation strategy, revenue sources, and revenue streams. The report presents the impact that a VUCA environment during the period of successive COVID waves had on the companies’ revenue models and their ability to generate profitable income. It also examines the actions companies undertook to exploit the opportunities and minimize threats in the short-term period and to face challenges in the medium and long term. The empirical results presented in the report are based on two studies carried out by SRC "Innovations and Competitiveness" (U2B) at UNWE in the period March 2020-March 2021.

The Turkish Table
Authors: Işın Priscilla Mary
Published: April 2024

There is a long tradition of humour in Turkish oral and written literature, ranging from slapstick to satire. Forms include anecdotes, jokes, riddles, comic verse, nonsense rhymes, humorous narrative, and witty debates characterized by plays on words, insight into human nature and a keen sense of the ridiculous. Within this tradition, food and food culture figure widely; not because food is intrinsically funnier than any other subject, but because of its deep-seated role in society. This paper concerns how humour has played a part in a particular type of occasion, known as a Helva Party, where guests participate in making this pudding as well as describing other instances where food and humour converge in literature and folklore.

The Workers' Reward at Middleton Hall 1567
Authors: Dawson Mark
Published: April 2024

The evidence for the ‘feast’ explored in this article is found in the house­hold, personal and estate accounts of the Willoughby family, whose main residences in the sixteenth century were Wollaton Hall, near Nottingham and Middleton Hall in Warwickshire. This paper looks at what workers performing "boon work" (not paid for except by a meal) would have been fed by the gentry who received their assistance on a particular occasion in May 1567.
Comparative Characteristics of Patients Structure in the Orthopedics Department of a Clinical Hospital in a Region Remote from the Front Line during Peacetime and the First Year of a Full-Scale War in Ukraine

Published: April 2024

Objective. To analyze changes in the nosological structure of patients, treatment technologies, to outline the peculiarities of surgical interventions in the trauma profile of a civilian clinical hospital during the war period and to emphasize the need for relevant knowledge and skills of specialists in the treatment of combat trauma and its consequences.Methods. A comparative analysis of the clinical and nosological structure of 2,475 patients were treated during the year before the war and 3,838 patients during the full-scale war year. Among them, 83.1 % were civilians, 7.7 % were temporarily resettled, and 9.2 % were military personnel. The study utilized bibliosemantic, medical-statistical, and clinical methods. Results. During the active phase of the war, the Orthopedics Department of the civilian clinical hospital provided specialized medical assistance to both civilian populations and military personnel injured during hostilities. The relative number of hospitalized men increased by 4.83 %, and although the absolute number of those urgently hospitalized decreased. Despite the overall increase in the number of operations per patient, surgical activity in the Orthopedics Department decreased from 86 to 80 %. The intensification of inpatient treatment organization, patient preparation for subsequent stages of surgical interventions in the Rehabilitation Department, and outpatient medicine work collectively reduced the average bed-day in the Orthopedics Department by 12.3 %. Conclusions. Thus, during the war, the structure of patients in the Orthopedics Department of the civilian medical clinical institution changed, with an increase in the relative number of male patients and those with multiple and combined injuries. A notable feature of the treatment process organization during hostilities is the phasing of the treatment of the wounded not only at the levels of medical evacuation but also within the clinical hospital. The intensification of the organizational component and the outpatient link of the treatment process allowed for a reduction in bed-days and the provision of inpatient treatment to a larger number of patients.
The Materiality of Scribal Practice in Isaiah 8:1–2: Papyrus, Pens, and Authority in Inscribing Prophecy
Authors: VanDyke Elizabeth
Published: April 2024

Isaiah 8:1–2 is an elusive text, in regard to both its interpretation and its import. In these verses, YHWH commands Isaiah to write למהר שלל חש בז on a large גליון with a חרט אנוש. The writing surface, writing tool, and message are obscure and contested. However, I argue that the puzzle of Isaiah’s writing materials has not yet been persuasively solved, as scholarship has failed to consider Judah’s Egyptian scribal heritage. With this context, the prophet’s writing surface (גליון) can be correctly understood as a section of papyrus, and his tool (חרט אנוש) can be read as a red rush pen. These proposed identifications of Isaiah’s tools harmonize with comparative, etymological, epigraphic, and art-historical evidence for scribalism in the Levant and Egypt. Moreover, they illuminate the purpose and genre of YHWH’s message. It appears that Isaiah was borrowing the format and tropes of royal decrees, which were transcribed on large pieces of papyrus in front of witnesses. The use of red ink also hints at the text’s significance. The scene described in Isa 8:1–2 thus indicates that prophecy had taken on the garb of written record. The word of God was becoming not just an oral message but an authoritative document.
Thomas in Alexandria: Arguments for Locating the Gospel and Book of Thomas in Alexandria
Authors: Litwa M. David
Published: April 2024

In this article, I argue that the Gospel of Thomas and the Book of Thomas were composed in Alexandria, Egypt. For the Gospel of Thomas, I examine the manuscript attestation and quotations of the gospel from known Alexandrian figures (e.g., Julius Cassianus, Basilideans) and texts (the Gospel according to the Egyptians), and from texts that are arguably Alexandrian (e.g., the Testimony of Truth, Excerpts from Theodotus, and the Naassene discourse). With respect to the Book of Thomas, I examine the treatise’s use of the tradent Matthias, the Philonic paradigm of the spiritual athlete, the use of the Alexandrian Apocalypse of Peter, and distinctive overlaps with other Alexandrian figures and texts. Determining the provenance of anonymous ancient texts is hypothetical, but the most reliable and precise evidence for the Gospel and Book of Thomas supports a composition in Alexandria more so than it does the regions of Edessa, Jerusalem, or Antioch.
Negacionismo: definições, confusões epistêmicas e implicações éticas
Authors: Gomes Sally Ramos , Zamora Maria Helena
Published: April 2024

Resumo: Durante a pandemia da COVID-19, o negacionismo científico teve uma imensa repercussão midiática e a palavra negacionista se tornou um dos termos depreciativos mais utilizados no Brasil. Porém, nem sempre ele é definido com precisão, em toda a sua complexidade e nuances. A utilização errônea de conceitos pode criar confusões epistêmicas com noções adjacentes, que não equivalem ao negacionismo, como ceticismo, ignorância, pseudociência ou agnotologia. O objetivo do presente artigo é definir negacionismo, com base em revisão teórica, e diferenciá-lo destes termos. Como conclusão, propõe-se uma reflexão sobre as implicações éticas do negacionismo, que pode levar à perda de vidas em casos extremos, e da importância do letramento científico na tomada de decisões.
Relevância de Deus para a evolução biológica: percepções de professores de Biologia em três países latino-americanos
Authors: Silva Heslley Machado
Published: April 2024

Resumo: Na América Latina, o ensino da evolução se tornou um tema delicado devido às constantes mudanças no panorama religioso. Este estudo analisa as concepções dos professores sobre a evolução em três países latino-americanos: Argentina, Brasil e Uruguai, com diferentes níveis de secularismo. A importância de Deus na evolução das espécies foi analisada por meio das respostas à pergunta B.48 do questionário Biohead-Citizen. As respostas dos professores argentinos e uruguaios não consideraram Deus importante para a evolução, apesar de serem majoritariamente religiosos. Em contraste, muitos professores brasileiros buscaram integrar a ciência com a religião no contexto da evolução e acreditam que Deus é importante para o processo evolutivo. Entrevistas semiestruturadas e outras respostas do questionário confirmaram essas conclusões.

The digital transformation applied to bed management in hospitals
Authors: Freitas Rute , Araújo Claudia
Published: April 2024

Abstract Purpose: This article aims to identify the benefits and difficulties managers perceive regarding implementing digital transformation (DT) in hospital bed management. Originality/value: The article contributes to academia by analyzing a rele-vant topic, DT of health, that is scarcely explored in the multifactorial perspective of its technological, organizational, and social elements. No similar study was identified with application in a large private hospital located in a developing country. By analyzing managerial perceptions about implementing DT applied to hospital bed management, the study allows a better understanding and potential strengthening of this DT process by the professionals involved, which can contribute to expanding access to hospital care. Design/methodology/approach: A single case study was carried out to investigate the implementation of DT for managing hospital beds in a private general hospital in São Paulo, Brazil. We interviewed 19 managers responsible for hospital bed management. The interviews were analyzed using two methods: content analysis and data mining, and they were classified according to their technological, organizational, and social elements (Reis et al., 2018). Findings: DT’s most cited potential benefits were efficiency gains, real-time information, and employee and patient satisfaction. The main dificulties reported were systems integration, data availability in real-time, instituting new processes, and challenges related to organizational culture and the necessary changes. DT can positively impact bed flow management, but it is crucial to consider the technological, organizational, and social elements involved in its success.
Oscilador anarmônico clássico com simetria U(1): por que deve haver dinâmica em uma teoria de calibre?
Authors: Perovano M.M.F. , Spalenza W. , Belich H. , Helayël-Neto J.A.
Published: April 2024

A simetria de “gauge” e, em consequência, as teorias de calibre, que de forma natural se estabeleceram no contexto da teoria eletromagnética, constituem uma abordagem muito apropriada e bem-sucedida para descrever as interações eletrofracas e fortes, e consolidaram as teorias quânticas de campo como uma formulação universal para tratar as diferentes interações fundamentais. O sucesso desta proposta é devido ao fato de que, incluindo um campo de calibre como mediador de uma dada interação, emerge um formalismo padrão para descrever os campos de força conhecidos. Nesta contribuição, adotamos o exemplo dos osciladores bidimensionais harmônicos/anarmônicos clássicos para apresentar, de forma introdutória, o procedimento geral de construção de uma teoria de calibre. Para relacionar esta discussão com um cenário de uma teoria de campos, partimos da eletrodinâmica escalar e utilizamos a técnica de redução dimensional para se chegar à lagrangiana de um sistema mecânico. E, com este exemplo, tentamos motivar e mostrar por que é necessário que os campos de calibre devem corresponder a graus de liberdade dinâmicos.

Authors: Silva Fernanda Roberta de Faria Rocha da , Simões-Zenari Marcia , Nemr Katia
Published: April 2024

ABSTRACT Purpose To describe the knowledge of amateur singers who perform in religious services, about vocal health and hygiene, and compare these findings at two different moments. Methods Descriptive, longitudinal research with 100 participants who practice amateur singing in religious services; ages between 18 and 82 years (average 33.72 years), 54 women and 46 men. Participants answered the Initial Questionnaire (Q1), which includes personal data and vocal self-assessment, and the Vocal Health and Hygiene Questionnaire (QSHV), on two occasions with an interval of 20 days and with the questions randomized. The participants were given a feed-back of the QSHV after each application i.e. the correct answers to each item. The data were analyzed descriptively and inferentially. Results Most singers reported some degree of self-assessed vocal alteration and reported at least one vocal symptom (mainly throat clearing and voice failure). The score was higher in the second application of the QSHV and there was no correlation between the vocal self-assessment and the score obtained in the QSHV. Conclusion Amateur singers of both sexes who perform in religious services demonstrated knowledge about vocal health and hygiene corresponding to that of vocally healthy individuals, above the cutoff point in both applications; however, the majority reported vocal changes and symptoms. There was an increase in knowledge about vocal health and hygiene in the second application, however discreet. The level of knowledge about vocal health and hygiene did not correlate with the degree of vocal alteration.

Published: April 2024

ABSTRACT The aim of this study was to assess the internal quality of free-range eggs available for sale in Alfenas – MG, Brazil, and stored under refrigerated conditions (maximum and minimum temperatures of 9.7 and 6.7 °C, respectively). The experimental design was completely randomized, structured as a 2x5 factorial arrangement involving two types of retail outlets (supermarket (S) and open-air market (OA)) and five storage periods (1, 8, 15, 22, and 29 days), resulting in 10 treatments. Each treatment had six replicates, represented by individual eggs. The following parameters were evaluated: Haugh unit (HU); percentage of egg weight loss (WL%); percentages of albumen, yolk, and shell; yolk index (YI); albumen index (AI); yolk pH; and yolk color. Egg weight loss increased (p<0.05) with the length of the storage period. Eggs acquired from S were deemed to be of inferior quality (HU < 60), in contrast to those obtained from OA (p<0.05). A significant interaction effect was noted for YI (p<0.05), with eggs from S exhibiting higher YI values than those from OA at 15 and 22 days of storage. Additionally, eggs from S had diminished AI values (p<0.05) when compared to those acquired from OA. The yolk color in eggs from S was more intense than that in eggs from OA (p<0.05). A lower yolk percentage was detected in eggs from S relative to those from OA (p<0.05). Therefore, eggs sold in Alfenas – MG, Brazil, from open-air markets possess superior quality compared to those sold in supermarkets.

Heterophase synthesis of rare-earth zirconates
Authors: Nikishina E. E. , Grechishnikov N. V. , Drobot D. V.
Published: April 2024

This study focuses on developing a heterophase process for synthesizing rare-earth zirconates, specifically R2Zr2O7 /R2O3·2ZrO2 (R = La, Sm, Gd, Dy). We investigated the sorption properties of low-hydrated zirconium hydroxide, a precursor for complex-oxide phases, towards rare-earth elements' ions (La, Sm, Gd, Dy). The results indicate that sorption by low-hydrated zirconium hydroxide is a multifaceted process, involving the incorporation of rare-earth cations into the pores of low-hydrated hydroxide and ion exchange. The paper details the synthesis of R2Zr2O7 /R2O3·2ZrO2 (R = La, Sm, Gd, Dy), considering both «light» and «heavy» elements. The process process involves the interaction between Zr(OH)3÷1O0.5÷1.5·(1.6÷2.6)H2O, low-hydrated zirconium hydroxide, and an aqueous solution of rare-earth acetate (С(La3+) = 0.155 mol/l, С(Sm3+) = 0.136 mol/l, С(Gd3+) = 0.141 mol/l, С(Dy3+) = 0.120 mol/l) followed by heat treatment. The resulting phases and their thermolysis products were analyzed using differential thermal analysis and X-ray phase analysis. Single-phase rare-earth zirconates R2Zr2O7 (R = La, Sm, Gd) and the Dy2O3·2ZrO2 solid solution were only obtained at 800 °С. The lattice parameters are calculated for each phase. Lanthanum, samarium, and gadolinium zirconates exibited a cubic pyrochlore structure (Fd3–m), while dysprosium displayed a fluorite structure (Fm3–m). The average particle size of all zirconates was 1.14 ± 0.02 μm.

Published: April 2024

In recent years, the development of additive technologies has been one of the priority tasks in the sector. Primarily, additive technologies enable the effective implementation of various design and engineering ideas in high-tech industries, such as the aircraft industry, engine technology, and rocket engineering. The expanded range of standardized materials for additive technologies will facilitate their integration into large-scale production. Of significant interest is the potential use of nitrogen-containing heat-resistant powder alloys to produce complex-shaped aircraft parts using additive technologies. This paper describes the complete process of obtaining samples from powders of alloys with superequilibrium nitrogen content using the selective laser melting (SLM) method. Four different compositions of high-nitrogen steels were obtained through mechanical alloying. Subsequently, the powders of these steels underwent processing using the plasma spheroidization method to be utilized in the SLM process. The SLM method was also employed to produce samples for mechanical tests. Throughout each stage of the process, the powders were thoroughly analyzed. One of the most critical parameters was the nitrogen content in the resulting powders. At each subsequent production stage, its proportion decreased, yet it remained at the superequilibrium content level of 0.13–0.44 wt. %. The mechanical tests confirmed that the alloys fabricated by the SLM method are not inferior in terms of their properties compared to those obtained using classical metallurgical technologies.
Effects of intermittent overload doses of oral vitamin D3 on serum 25(OH)D concentrations and the incidence rates of fractures, falls, and mortality in elderly individuals: A systematic review and meta-analysis

Published: April 2024

Vitamin D is commonly used to prevent and treat osteoporosis, with studies indicating its potential to reduce fractures, falls, and mortality. However, meta-analyses present inconsistent findings regarding its efficacy, particularly reflecting significant variability in data and outcomes related to various dosing regimens. In this meta-analysis, we assessed the impact of high-dose intermittent oral administration of vitamin D3 on serum 25(OH)D levels, fractures, falls, and mortality among elderly individuals. We included 14 randomized controlled trials (RCTs) and employed Review Manager 5.4 for statistical analysis. Our findings indicate that intermittent monthly administration of vitamin D3 (over 800 IU per day) significantly raised serum 25(OH)D levels at all timepoints after six months, maintaining levels above 75 nmol/L throughout the year. This regimen showed no increase in all-cause mortality, with a risk ratio (95% CI) of 0.95 (0.87-1.04). Likewise, it did not significantly reduce the risks of falls and fractures, with risk ratios of 1.02 (0.98-1.05) and 0.95 (0.87-1.04) respectively. Although one-year intermittent administration significantly increased the concentration of 25(OH)D in serum, further research is needed to determine if this method would increase the incidence of falls. Therefore, it is not recommended at this stage due to the lack of demonstrated safety in additional relevant RCTs. This study had been registered at PROSPERO (CRD42022363229).

The handling of the ball is considered to be a determining factor in the precision and power of handball throws. To facilitate ball handling, the rules allow players to use an adhesive material called ‘resin’. The aim of the study was to analyse the influence of the resin on the throw velocity and accuracy, both in men and women in formative (U-18) and senior categories. The sample consisted of 46 players (31 men and 15 women) who performed a protocol of 6 distance throws with the intention of maximum velocity and accuracy. Randomly, each subject threw 3 times without resin and 3 times with resin. The results showed a higher velocity with the use of resin in the whole sample analysed. Throws with resin were 6.56% faster (p < 0,001). However, no significant differences in throwing accuracy were found (p > 0,05). Furthermore, no differences were found between the analysis subgroups (p > 0.05). The use of resin seems to be a determinant of throwing velocity. These results are highly applicable both in the field of sport training and for the evaluation of the importance of the throw in the offensive performance of a handball team.

In this study we try to observe, code and analyze the performance that different tactical systems offer to a professional soccer team. Through the observational method and the use of the SWOT analysis tool, the use of the game systems of the matches carried out before the covid19 (n = 25) of the 19-20 season is analyzed. Performance-related variables were analyzed taking into account the gaming system used and its context, in addition to performing a SWOT that would allow obtaining data on strategic factors of each system. The game systems were (1-4-2-2-2; 1-3-1-4-2; 1-3-4-3; 1-3-4-1-2; 1-4-2- 3-1). The 1-4-2-2 system was the most used (52%), it achieved more victories (57.14%), more draws (50%), most used as a visitor (46.15%) and at home (58.33%). The 3-defense game system prevailed when the rival used a striker (54.55%) and at the offensive level a system with two forwards was used 83% of times against a defense of 3. We can conclude that the analyzed team obtained a high performance After using a wide variety of game systems, obtaining advantages in competition that the SWOT tool helps us to collect in a simple, economical and efficient way.

The aim of this study was to analyze the current rules of play of the different regional basketball federation in Spain, in the under 10, under 12, under 13 and under 14 (U10, U12, U13 and U14), with incidence on the following variables: a) mode disputed, b) players called; c) time of the game; d) breaking times and time outs; e) change system; f) ball size; g) three-point line distance; h) score system and i) other modifications. The most significant results showed: a) a wide variety of rules in the under 10 and under 12 levels; b) a lack of consensus regarding the distance of three-point line, change system and size ball in the under 13 level, and c) a wide consensus from under 14 level. Despite the wide variability in the basketball's use game in the young levels in the different federations, it can be concluded that: a) in the last years it has been observed constant changes; b) the regional federations act in isolation; c) there is a shortage of scientific criteria for the choice for its rules proposals. It is proposed a permanent search of rules modifications, supported by scientific evidences.

The intervention of female basketball Players during competition has not been widely studied. In addition, it is necessary to differentiate their intervention according to the specific position they occupy. The intervention of the Players is in turn conditioned by the competitive phase. The objectives of this work were to identify the differences in the performance indicators in professional basketball Players based on their role and discover the differences in the performance indicators based on the competition phase. For this, an empirical, descriptive and observational study was carried out, analyzing 572 matches of the 78 days of the regular phase and 20 of the Play-Offs between the 2015/2016, 2016/2017 and 2017/2018 seasons. The game indicators recorded by the competition were normalized according to the minutes Played in order to make comparisons. The Mann-Whitney U Test was performed to identify differences in performance indicators between specific roles in function of competition phase. A change in the intervention of the Players is identified depending on the competition phase. The bases have a greater contribution in the field shots and 2 points during the regular league. Guards and power forwards increase their effectiveness in the Play-Offs on 3-point shooting. Power forwards during the regular season provide more free throws. Finally, during the PlayOffs, the collective game is favored by the contribution of the bases through assists and the defensive game with the contribution of the pivots, through rebounds and the defensive intensity of the forwards. Relevant information can have important applications such as training preparation, prior planning of the competition, making changes to matches, specific instructions on Players and making signings that meet the needs of the team.

The aim of this study was to analyze and compare the spatial performance indexes of laterality and depth as a function of the final classification of the teams that competed in the men's (Germany-Denmark 2019) and women's (Germany 2017) senior handball world championships, considering for this aim the total number of throws made as a function of the finishing zones. A documentary study was carried out based on the total number of throws made in 192 men's and 154 women's participations of 48 national teams belonging to 33 countries, which participated in the previous World Cups. The data were collected by the IHF. The results showed that the lower ranked teams in both World Cups compared to the champions finished a greater number of times both from the side lanes of the field and from shallow offensive areas. This information will be useful for coaches in improving their training design and for players in their decision making.

Opentrons Dual-Index Primer Plate Workflow v2
Authors: Douglas Russell Stephen
Published: April 2024

This protocol is designed to utilize the Opentrons robotic automation platform to generate dual-index primer - master mix plates for PCR reactions for NGS, particularly for DNA barcoding large specimen pools with Oxford Nanopore Technologies (ONT) MinION devices. It is designed for the indexing strategy where you start with a plate of 96 different forward or reverse primers, and then use a single forward/reverse index for each PRC plate you are running for the pool. I typically use eight plates (768 reactions) of specimens for a given Flongle run. So each plate of reactions has a single unique forward tag corresponding with that plate number and a standard plate of 96 reverse tags. The protocol is broken down into three primary areas. 1. OT-2 "Working" Primer Plates - 100uM->10uM These steps and automated protocol turns a single 100uM primer plate into four 10uM "working" primer plates. 2. OT-2 Dual-Index PCR Stock Plates This portion of the protocol will generate four "stock" dual-index primer / master mix plates. Each of these stock plates will generate 16 PCR ready plates for a single ONT single index (Ex - ONT01). This protocol will need to be repeated twice to create stock plates for each of the eight unique indexes for a run. 3. OT-2 Dual-Index PCR Ready Plates This protocol will create eight PCR ready plates from one PCR stock plate. Each cell has half-reactions (11.5uL; 12.5 total reaction volume with template) or quarter-reactions (5.7uL; 6.3uL total reaction volume). At the end of this step, you are left with dual indexed PCR plates that are ready for DNA template to be added and to be put in the thermocycler.
