:

Owing to their unique characteristics and diverse surface activities, gold nanoparticles (AuNPs) have been widely used in various fields of biology. The ease with which AuNPs can be functionalized makes it a useful platform for nanobiological assemblies containing oligonucleotides, antibodies, and proteins. AuNPs bioconjugates have also emerged as an interesting candidate for the development of novel biomaterials for the study of biological systems. AuNPs' flexibility has made them valuable in a variety of biomedical applications. The binding of analytes to AuNPs can change the physicochemical features of AuNPs, such as surface plasmon resonance, conductivity, and redox activity, resulting in observable signals in diagnostics. AuNPs can also be used as a therapeutic platform because of their large surface area, which allows for a dense presentation of multifunctional moieties (e.g., drugs and targeting agents). We present a brief summary of green synthesis, characteristics, and applications of gold nanoparticles in this paper, as well as their translational potential.
Design and Structural Testing of Blades for a 2MW Floating Tidal Energy Conversion Device
Authors: Jiang Y.
Published: December 2021

Abstract. The floating tidal energy is increasingly recognised to have the potential of delivering a step-change cost reduction to the tidal energy sector, by extracting energy from deeper water sites through energy conversion devices. To ensure the normal operation of a tidal energy convertor within its service life, the device should be designed properly and evaluated through a series of strength and durability testing. The Large Structures Research Group at NUI Galway is working closely with, renewable energy company, Orbital Marine Power and, blade manufacture, ÉireComposites Teo, to design and test the next generation of SR2000 tidal turbine blade, with aims to increase the turbine power production rate and to refine the design for low cost. This paper presents a brief description of the structural design and testing of a blade for the O2-2000 tidal turbine, one of the largest tidal turbines in the world. NUI Galway will utilise their in-house software, BladeComp, to find a blade laminates design that balances both blade strength and material cost. The structural performance of the designed blade will be assessed by conducting static and fatigue testing. To achieve this objective, a support frame to fix the blade is designed, a load application device is introduced and the methodology for design tidal loading conversion is proposed in order to complete the testing at NUI Galway.
A Review of Rapid Distortion Theory
Authors: Basu S.L.
Published: December 2021

Abstract. With the depleting non-renewable fuel sources like coal and an ever-increasing demand for energy, we need to start looking into renewable energy sources. These are of paramount importance for a sustainable and green future. Wind Energy is one of the most important sources of renewable energy. But, setting up a wind farm requires considerable land area and land acquisitions are often faced with legal hurdles. This necessitates setting up offshore wind turbines. But, when we talk about offshore wind farms, we need to address the age-old phenomenon: “Turbulence”. Presently, we are trying to develop enhanced controllers for wind farms which will increase the efficiency of the wind farms. The effects of rapidly changing wake aerodynamics i.e. breakdown of strong tip and hub vortices mixed up with low intensity turbulence in the inflow of the rotor and counter-rotation of the wake i.e. determinate velocity component in wake turbulence field will affect the overall performance of the wind farm. This paper provides a brief review on Rapid Distortion Theory (RDT) to model the turbulence.
Usability Testing of a Patient-Centered Mobile Health App for Supporting and Guiding the Pediatric Emergency Department Patient Journey: Mixed Methods Study
Authors: Rochat Jessica , Ehrler Frédéric , Siebert Johan N , Ricci Arnaud , Garretas Ruiz Victor , Lovis Christian
Published: December 2021

Background

Patient experience in emergency departments (EDs) remains often suboptimal and can be a source of stress, particularly in pediatric settings. In an attempt to support patients and their families before, during, and after their visit to a pediatric ED, a mobile health (mHealth) app was developed by a multidisciplinary team based on patient-centered care principles.

Objective

This study aims to evaluate the usability (effectiveness, efficiency, and satisfaction) of a new mHealth app, InfoKids, by potential end users through usability testing.

Methods

The app was assessed through an in-laboratory, video-recorded evaluation in which participants had to execute 9 goal-oriented tasks, ranging from account creation to the reception of a diagnostic sheet at the end of the emergency care episode. Effectiveness was measured based on the task completion rate, efficiency on time on task, and user satisfaction according to answers to the System Usability Scale questionnaire. Think-aloud usability sessions were also transcribed and analyzed. Usability problems were rated for their severity and categorized according to ergonomic criteria.

Results

A total of 17 parents participated in the study. The overall completion rate was 97.4% (149/153). Overall, they reported good effectiveness, with the task successfully completed in 88.2% (135/153) of cases (95% CI 83%-93%). Each task, with the exception of the first, created difficulties for some participants but did not prevent their completion by most participants. Users reported an overall good to excellent perceived usability of the app. However, ergonomic evaluation identified 14 usability problems occurring 81 time. Among these, 50% (7/14) were serious as their severity was rated as either major or catastrophic and indicated areas of improvements for the app. Following the suggested usability improvements by participants, mitigation measures were listed to further improve the app and avoid barriers to its adoption.

Conclusions

Usability of the InfoKids app was evaluated as good to excellent by users. Areas of improvement were identified, and mitigation measures were proposed to inform its development toward a universal app for all ED patients visiting a digitalized institution. Its contribution could also be useful in paving the way for further research on mobile apps aimed at supporting and accompanying patients in their care episodes, as research in this area is scarce.
Designing an Adaptive Adolescent Physical Activity and Nutrition Intervention for COVID-19–Related Health Challenges: Formative Research Study
Authors: Grimes Amanda , Lightner Joseph S , Pina Kimberly , Donis de Miranda Evelyn S , Meissen-Sebelius Emily , Shook Robin P , Hurley Emily A
Published: December 2021

Background

With rates of childhood obesity continually increasing, effective physical activity and nutrition interventions are needed. Formative research is used to tailor interventions to different cultural and geographic contexts and can be vital in adapting intervention strategies in the face of significant disruptive circumstances (like COVID-19).

Objective

We conducted formative research via in-person and web-based focus groups among middle schoolers and parents to better understand the facilitators and barriers to physical activity and fruit and vegetable consumption and to inform the design of a large intervention for a low-income, urban setting in the US Midwest.

Methods

We conducted 2 phases of qualitative focus groups with parents (n=20) and 6th-9th grade middle schoolers (n=23). Phase 1 was conducted prior to the COVID-19 pandemic in late 2019, and phase 2 was conducted during the COVID-19 pandemic in the summer of 2020. Focus groups were transcribed and thematically coded using the Dedoose software.

Results

The main facilitators of physical activity prior to the pandemic included the opportunity to have fun, peer influence, competition (for some), and incentives, while the main barriers to physical activity were time constraints and social discomfort. The main facilitators of eating fruits and vegetables included parental influence, preparation technique, and convenience, while barriers included dislike of vegetables, time constraints, and preparation or freshness. During the pandemic, facilitators of physical activity remained the same, while additional barriers to physical activity such as lack of motivation and limited time spent outside of the home were reported. For fruit and vegetable consumption, both facilitators and barriers remained the same for both time periods. Additionally, for some participants, the pandemic offered an opportunity to offer more fruits and vegetables to middle schoolers throughout the day.

Conclusions

Some themes identified were common to those reported in previous studies, such as peer influence on physical activity and parental influence on fruit and vegetable consumption. Novel themes such as lack of motivation to be active and limited time outside the home helped improve intervention adaptation, specifically during the COVID-19 pandemic. The continuity of formative research after a major unexpected change in the intervention context can be essential in targeting areas of an intervention that can be retained and those that need to be adjusted.

Published: December 2021

The global community is currently harnessing the lessons learnt from the COVID-19 Education response, to build more resilient education systems. This can effectively be achieved via empirical evidence of the experiences of all stakeholders in education in all nations during the COVID-19 pandemic and lockdown. The purpose of this study was to explore student factors in the lecturers’ experience of their online emergency remote teaching (ERT) in the College of Education, Agbor, Delta State, Nigeria during the COVID-19 lockdown. Using a quantitative descriptive design, the lecturers completed a structured questionnaire about their online ERT experiences. The findings suggest that generally, the students chose the familiar WhatsApp (chat and voice) messaging as against the use of zoom and other platforms for the ERT. Top students’ challenges are:unpreparedness for the ERT.experience of unavailable/unstable network/internet access andinability to purchase enough data.In addition, students lacked:smart phones/laptops/computers,necessary ICT skills, anddid not embrace the ERT, although it engaged them academically during the lockdown.Based on these results and in view of prevalent/imminent lockdown due to emerging new variants of the COVID-19 such as delta and omicron, interventions/strategies for achieving successful and satisfactory online teaching are recommended.

Published: December 2021

Un satélite es un dispositivo que se sitúa en órbita alrededor de la Tierra con fines científicos, militares, educacionales o de comunicaciones. Se pueden clasificar según su peso como: satélites grandes, que pesan más de 1,000 kilogramos (kg), satélites medianos, que pesan entre 500-1,000 kg, y satélites pequeños, que pesan menos de 500 kg. Dentro de los satélites pequeños se encuentran los nanosatélites, los cuales pesan entre 1-10 kg. La principal ventaja que poseen los nanosatélites es que son capaces de realizar misiones complejas a un menor costo. Dentro de las limitaciones que estos presentan es que tienen poca capacidad para captar y almacenar energía debido a su tamaño. Considerando la importancia del sistema de energía durante el funcionamiento de los satélites, este artículo analiza los modos de fallos que se presentan en el sistema y cómo estos afectan a los sistemas de generación y almacenamiento de energía. Para la simulación de estos sistemas se determinaron la cantidad mínima de paneles solares y baterías necesarios para su correcto funcionamiento. Los resultados obtenidos muestran que con este análisis se logra dimensionar correctamente el sistema de gestión de energía, reduciendo el tamaño de estos y a su vez el peso dentro del satélite.

Published: December 2021

Se analiza el discurso de la niñez venezolana como sujetos de migración forzada, a fin de explorar el significado que para ellos tiene el proceso migratorio experimentado y hacer visible sus ideas y representaciones del mismo, pues frecuentemente están ausentes en las agendas públicas. Estudio exploratorio y cualitativo realizado con cuatro niños y dos niñas, durante tres encuentros, usando como técnicas lluvia de ideas y conversaciones, a cuyas textualizaciones se les aplicó análisis de contenido siguiendo los aportes de Glaeser y Strauss (1967). Los resultados destacan: expresiones de desarraigo relativas al nuevo territorio, dificultades de integración por el rechazo como migrantes, al tiempo que en sus discursos interpretan el contexto social que les envuelve. Se percibe, aun cuando reconocen aspectos positivos del país de acogida, la necesidad de ofrecer programas de acompañamiento que permita incorporar sus ideas, garantizándoles sus derechos, en los proyectos educativos que contemplen la diversidad multicultural de la niñez migrante.
Deterioration of Accuracy Characteristics of Solid-State Wave Gyroscopes when the Excitation Frequency Is Adjusted from the Resonance Frequency
Authors: Vikhlyaev I.A. , Shishakov K.V. K.V.
Published: December 2021

The paper presents the calculated and experimental study of the measure of deterioration of accuracy characteristics of solid wave gyroscopes when adjusting their frequency from the resonance one. To do this, a simulation model was built, which was researched in the Matlab package. The measurement device is modeled at the alternating and direct current. It is shown that the measure of mismatch of the calculation grid with the period of vibrations of the gyroscope resonator was the main reason for errors in calculating the angle of the gyroscope in the simulation model. This is confirmed by the graphs of dependencies of errors on the deviation of the excitation frequency from the resonance one. Experimental studies on laboratory models of non-industrial production confirmed the principle possibility of making a solid-state wave gyroscope design without the contour of phase auto-adjustment frequency, without a significant loss of the accuracy. To do this, three models of low-precision gyroscopes were created and researched. In the first layout, a variable-current measuring device was used, and the parametric swing of oscillations was performed by one ring electrode with an additional inclusion of a different-frequency correction path with sixteen electrodes. In the second layout, the previous diagram replaced the measuring device for working on a direct current. The third mock-up examined a two-channel eight-electrode control system. On all layouts it was permissible to work at the excitation frequency deviation from the resonant 5 kHz equal to the value (20 Hz). At the same time, the form of the systematic drift function has not changed much. And its amplitude and random error rate also changed acceptably.

Arab Journal of Plant Protection, 39(4): 323-328. https://doi.org/10.22268/AJPP-039.4.323328 This study was conducted on six medicinal plants viz., Vitex negundo (leaves), Xanthium strumarium, Caesalpinia bonduc, Mucuna pruriens, Moringa oleifera (seed kernels), Tagetes erecta (petals) for their bio-insecticidal activity. The powders of various parts of plants were extracted using the MARS6 microwave acid digestion system. Three different concentrations (20, 30, and 40%) of plant extracts were tested against granary weevil, Sitophilus granarius L. (Coleoptera: Curculionidae) for their bio-insecticidal activities under laboratory conditions. The results of statistical analysis showed a good performance of all plant extracts, especially at the high concentrations of the extracts, where they showed different levels of insect mortality and their developmental rate was also reduced leading to significant reduction in insect numbers. The mortality rate ranged was 0-100% with S. granarius adults (p < 0.01). There was significant correlation (R=1) between mortality rate and the concentration of plant extracts. However, the extract of Mucuna pruriens with solvents (Acetone + Petroleum Ether) showed the highest mortality rate of 100% at the three concentrations used (p < 0.01), whereas, the lowest average mortality of 43.3% (p < 0.01) was observed with Xanthium strumarium and Vitex negundo extracts with solvents (Methanol + n-Hexane) compared with 0% mortality in the control. All plant extracts have revealed insecticidal as well as propitious protective effect on grains, and it can be selected as effective control treatment after proper dose formulation to prevent weevil infestation in stored grains.

Lexicogrammatical aspects in English for dentistry acquisition materials
Authors:   University of Latvia, Karapetjana Indra , Roziņa Gunta
Published: December 2021

In the 21st century, globalization and massive migration have increased the global demand for effective transnational communication skills in English in the health care workplace and academic contexts, including dentistry. English for Dentistry falls under the umbrella of English for Specific Purposes (ESP): this refers to teaching and learning English as a foreign language in a particular domain. While the role of grammar acquisition in ESP courses is often understated in the key theoretical literature on ESP, this article highlights the importance of lexicogrammatical knowledge. Dentistry students and practitioners in Latvia highly value the accuracy in communication since the knowledge of various syntactic and morphological rules of grammar and their use in the dentistry-related context contribute to the accuracy required in the performance of different communicative tasks, for instance, asking for, explaining, and providing information, giving instructions. Besides, if dentists are unable, for example, to explain a diagnosis, agree on treatment options with the patient in a meaningfully accurate way, the dentist’s authority may be undermined, resulting in unsuccessful communication. The case study reports on the tasks employing lexicogrammatical strategies in the material “Dentistry and Language Integrated Learning”, which has been developed by the authors of this article working in close collaboration with individual academic staff at the the Faculty of Medicine of the University of Latvia. The material piloted amongst both dentistry practitioners and students suggests that the applied strategies of morphological derivation, for instance, recognizing and building new words by gaining control of affixation devices, can be considered as useful tools in the new lexeme meaning-making process in dentistry. As a result, this study has attempted to support the assumption that ESP and content and language integrated learning (or CLIL) are compatible and can be efficiently mastered in the professional discourse development process.
Sufiksa -ul- desemantizēšanās Latvijas vietvārdos
Authors:   Latvijas Universitāte, Paidere Anita
Published: December 2021

Rakstā, balstoties uz piemēriem Latvijas toponīmijā, analizēts sinhroniskā aspektā desemantizējies sufikss -ul- un aplūkoti derivatīvie modeļi S + -ul- → S un S + -ul- + -āj- → S, galveno uzmanību pievēršot koku nosaukumu priede, apse, bērzs un liepa motivētiem atvasinājumiem. Vietvārdi, kas ir homonīmi sugasvārdiem, var sniegt vērtīgu materiālu dažādu valodas pārmaiņu procesu, t. sk. gramatizēšanās un desemantizēšanās, pētījumiem. Ja sufikss -ul- mūsdienu valodā zaudējis produktivitāti un arī vietvārdos atrodams daudz retāk, tad no mūsdienu vārddarināšanas viedokļa mazproduktīvs derivatīvais modelis S + -ul- + -āj- → S, galvenokārt saistīts ar atvasinājumu priedulājs, vietvārdos un arī uzņēmumu nosaukumos sastopams samērā bieži. Leksēma priedulājs, kura agrāk bija vērojama mežu, pļavu un purvu nosaukumos, mūsdienās vairāk saistīta ar oikonīmiem (pārsvarā mājvārdiem) un ergonīmiem (uzņēmumu nosaukumiem) un vairumā gadījumu tiek lietota daudzskaitļa formā priedulāji. Tradicionālajā onomastikā šādi toponīmu un onīmu kategorijas maiņas procesi tiek dēvēti par transtoponimizēšanos un transonimizēšanos. Neraugoties uz to, ka mūsdienu vārddarināšanā derivatīvais modelis S + -ul- + -āj- → S izmantots arvien retāk un tiek uzskatīts par mazproduktīvu, nosaukumu, kuru sastāvā ir leksēma priedulājs vai priedulāji, skaitam ir tendence pieaugt. Iespējamais skaidrojums varētu būt saistīts ar nosaukuma labskanību, semantisku piemērotību konkrētai vietai vai objektam, tomēr šāda atziņa būtu balstāma uz padziļinātiem pētījumiem, kā arī aptaujām par nosaukuma izvēles motivāciju.
Bērtin berot valodiņu: par kādu citu latviešu valodas verbālu konstrukciju korpuslingvistikas skatījumā

Published: December 2021

Rakstā aplūkota verbāla latviešu valodas konstrukcija, ko veido darbības vārds un apstākļa vārds pirms tā, turklāt šis adverbs ir atvasināts no tā paša verba, izmantojot piedēkli -us-/-šus-. Šo arhaisko darinājumu, kas tipisks latviešu tautasdziesmām, lieto arī mūsdienu latviešu valodā, kaut gan ievērojami retāk. Rakstā formulēti dažādi pētījuma jautājumi, arī tādi, kas pārsniedz latviešu valodas robežas – proti, kā šādu konstrukciju tulkot citās valodās. Minētā konstrukcija meklēta pieejamos latviešu valodas korpusos (galvenokārt LVK2018, lvTenTen14, InterCorp lv v13), un iegūtie lietojumi salīdzināti ar aprakstu pašreizējos latviešu valodas avotos – gan gramatikās, gan vārdnīcās. Novirzes no normas šajā rakstā aplūkotas deskriptīvi, resp., nevis kā kļūdas, bet gan kā runātāja vēlme panākt īpašu saziņas mērķi, kā arī šīs valodas parādības radoša attīstība mūsdienās. Raksts ir papildināts ar diviem pielikumiem: alfabētiskiem analizēto lemmu sarakstiem kopā ar to biežumu un nelielu fragmentu no iteratīvu konstrukciju datubāzes.

Publikācijā aprakstīts lībiskā dialekta dziļajām tāmnieku izloksnēm raksturīgais patskaņa  un tā fonētisko variantu e,  un a lietojums nomenu, verbu un adverbu gala zilbēs Popes, Ziru, Piltenes, Zlēku, Ances, Dundagas un Ugāles izloksnē. Pētījuma pamatā ir pētāmo izlokšņu runas dati, kas iegūti laikā no 2008. līdz 2019. gadam. Salīdzināšanai, kā arī aprakstāmās lingvistiskās parādības izplatības un dinamikas noskaidrošanai izmantoti 20. gs. 50. un 60. gados iegūtie izlokšņu materiāli, kas glabājas Latvijas Universitātes Latviešu valodas institūta (LU LaVI) izlokšņu arhīvā. Pētījuma rezultāti rāda, ka patskanis  dziļajās tāmnieku izloksnēs visbiežāk sastopams vienskaitļa un daudzskaitļa lokatīvā, mazāk – vienskaitļa un daudzskaitļa datīvā. Vietas adverbi, kas beidzas ar patskani  vai tā fonētiskajiem variantiem  un e, mūsdienās konstatēti visās pētāmajās izloksnēs. Ancē un Dundagā patskanis  un e joprojām saklausāms noteikto adjektīvu un kārtas numerāļu gala zilbēs.

Aim. An appraisal of practitioners with chronic constipation management details in older and senile adults.Key points. Chronic constipation is a common issue in geriatrics. Aside to age-related physiological bowel disfunction, a higher constipation incidence is conditioned by declined physical activity and frailty, polypharmacy and a series of secondary constipation-developing chronic states and diseases. Chronic constipation is associated with a higher risk of cardiovascular disease and complications, impaired general perception of health and pain, growing alarm and depression, and reduced quality of life. The treatment tactics in chronic constipation is cause-conditioned and should account for the patient’s history and therapy line, overall clinical condition, cognitive status and functional activity level. An essential baseline aspect of constipation management is apprising the patient and his family of the underlying factors and methods for non-drug and drug correction. An higher-fibre diet is recommended as first measure, with osmotic laxatives added and titrated to clinical response if none observed towards the non-drug and high-fibre regimens. Stimulant laxatives and prokinetics should be recommended in patients reluctant to fibre supplements and osmotic laxatives. Subsidiary correction includes biofeedback, transanal irrigation, acupuncture, foot reflexology and percutaneous tibial nerve stimulation.Conclusion. Elderly and senile chronic constipation is a prevalent multifactorial state requiring an efficient management via assessment and correction of total risk factors and consistent use of non-medication and drug therapies.

The tridharma of higher education in the form of education, research, and community service is the mandate of the legislation for universities. In implementing tridharma, universities should adapt to the development and needs of the community as well as science and technology (Science, Technology and the Arts). It can hardly be fulfilled by a university alone because of the growing needs of the society where all branches of science need to be integrated and connected. This study explained how collaboration could be applied in universities with a TQM approach. TQM has been widely used in various organizations and has proven its success for this approach was chosen in developing the existing collaboration model. Literature analysis method of TQM and collaboration was used in this study. The result is collaboration in fulfilling the Tridharma of higher education by using the TQM approach in a model stage could help organizations achieve previously agreed goals and adapt to existing science and technology needs.

Duas estruturas circulares geminadas, de aproximadamente 1 km de diâmetro cada, ocorrem na porção sul da região das minas do Seival (Caçapava do Sul, RS), em rochas da Formação Hilário (Grupo Bom Jardim da Bacia do Camaquã). Dentro das estruturas são descritas brechas piroclásticas monomíticas, formadas por blocos do andesito circundante, de até 1 m de comprimento. A matriz piroclástica da brecha é formada por litoclastos de andesito, cristaloclastos de plagioclásio e clinopiroxênio semelhantes aos fenocristais do andesito e cinza muito fina. Processos de fragmentação in situ em presença de fluidos são interpretados a partir de fraturas transgranulares e interclasto, muitas vezes dividindo fragmentos e cortando também a matriz de forma curviplanar, sendo geralmente preenchidas por calcita. A orientação de lineamentos estruturais e de planos de fraturas confirmam o trend regional NE – SW e ilustram o padrão localmente multi-direcional, característico das estruturas circulares. Dados gamaespectrométricos indicam o caráter shoshonítico dos andesitos (média de K 4,4%; U 4,4 ppm; Th 19,2 ppm; e contagem total 5070 cps), em contraste com a assinatura das brechas vulcânicas (média de K 1,7%; U 3 ppm; Th 6,1 ppm; contagem total de 2252 cps), e corroboram o contato mapeado. A integração destes dados permite interpretar as estruturas circulares como diatremas ou antigas chaminés vulcânicas.

Este trabalho apresenta novas constatações sobre a evolução do Granito Chasqueiro, uma das principais ocorrências de rochas graníticas cálcico-alcalinas alto-K no Cinturão Dom Feliciano, no extremo sul do Brasil. O objetivo deste trabalho é discutir as principais fontes e processos magmáticos envolvidos na evolução deste granito durante o Ediacarano (574 Ma), com base em novos dados de geoquímica isotópica (Sr-Nd, rocha total) em amostras representativas do granito e dos enclaves dioríticos associados. O granito mostra razões 87Sr / 86Sr(t) intermediárias (0,7095–0,7139), εNd(t) negativo (-0,36 a -2,94) e TDM entre 1,25 e 1,33 Ga. A amostra de enclave máfico apresenta razões 87Sr / 86Sr(t)  = 0,74672, mais elevadas que aquelas do granito, ƐNd negativo (-1,63) e TDM de 1,15 Ga. Com base nos dados de isótopos apresentados neste estudo, juntamente com dados geoquímicos de rocha total compilados de trabalhos anteriores, sugerimos que os principais processos de evolução magmática do Granito Chasqueiro são: (i) mistura de magmas, onde cada magmatismo (máfico e félsico) possui fontes e processos evolutivos diferentes; (ii) retrabalhamento crustal das rochas máficas e gnaisses do embasamento regional (εNd(t) negativo); (iii) processo de cristalização fracionada, marcado por concentrações e depleções expressivas em Ba, Sr, P, Nb, Ti, e Eu, que reforçam a extensa cristalização fracionada dos líquidos primários. Como resultado destes processos, o Granito Chasqueiro é altamente diferenciado, com composições semelhantes a granitos Tipo-I.

A pesar de algunas limitaciones éticas, los animales juegan un papel importante como  anfitriones sustitutos para investigar los mecanismos fisiopatológicos de enfermedades con el fin de indagar en ellos medicamentos contra diferentes patologías. Uno de los grandes problemas en salud pública a nivel mundial en el contexto farmacológico es la producción de antibióticos y la ocurrencia de resistencia microbiana, además, cada vez resulta más omplejo el uso de modelos animales por las restricciones bioéticas actuales, no obstante, es necesario usar modelos simples en los estudios preliminares que permitan evaluar las interacciones huésped-patógeno-antimicrobiano. Al validar que Caenorhabditis elegans es susceptible a varias bacterias y además tiene la capacidad de responder a estímulos ambientales con cambios observables en el comportamiento tras ser alimentado con diversas bacterias, resulta muy útil usarlo en este tipo de investigaciones ya que tiene una vida promedio corta y no cuenta con restricciones éticas para su uso. Por lo anterior, en este artículo se revisa la susceptibilidad que tiene C.elegans de infectarse con diferentes bacterias, además, ya que aún no se ha validado completamente como modelo para poner a prueba antimicrobianos se propone que este nematodo es útil como modelo In vivo para evaluar infecciones y tratamientos antibacterianos.
A Correlational Study on the Gross Domestic Product and Gross Domestic Product Per Capita of a Country and Its COVID-19 Incidence and Mortality Rates
Authors: Lopez Joseph Emmanuel G.
Published: December 2021

Some studies had shown that there is a relationship between the state of
the economy of a country and COVID-19 incidence and mortality rates.
However, these studies are mostly done on countries that are already
developed. This study aims to find the relationship between GDP and GDP
per capita and COVID-19 incidence and mortality rates in all countries.
In addition, they will also be analyzed based on their different income
levels. The data collected are from databases from World Bank and WHO
and are analyzed through MS Excel and JASP. Spearman’s rho is used to
analyze the overall data and stratified data. It has been found that the
GDP per capita and incidence (r = .656, p <
.001) and mortality rates (r = .521, p <
.001) have a strong and moderate correlation, respectively. GDP’s
relationship with incidence (r = .295, p <
.001) and mortality rates (r = .346, p <
.001) resulted in both weak correlations. Stratified analysis resulted
in no significant relationships, except for GDP per capita’s
relationship with incidence (r = .362, p = .011) and
mortality rates (r = .348, p = .014) in low-middle
countries, which yielded both weak correlations. These results show that
there is indeed a relationship between the incidence and mortality rates
and the economic status of a country before a pandemic, however, more
factors need to be accounted for in order to help countries improve
their pandemic response in the future.

Outer membrane lipoprotein A (OmlA) is a vaccine antigen against porcine
contagious pleuropneumonia (PCP), a disease severely affecting the swine
industry. Here, we aimed to systematically potentiate the secretory
production of OmlA in Corynebacterium glutamicum (C. glutamicum), a
widely used microorganism in the food industry, by establishing a
holistic development process based on our high-throughput culture
platform. The expression patterns, expression element combinations,
medium composition, and induction conditions were comprehensively
screened or optimized in microwell plates (MWPs), followed by
fermentation parameter optimization in a 4×1 L parallel fermentation
system (CUBER4). An unprecedented yield of 1.01 g/L OmlA was ultimately
achieved in a 5-L bioreactor following the scaling-up strategy of fixed
oxygen mass transfer coefficient (kLa), and the produced OmlA antigen
showed well-protective immunity against Actinobacillus pleuropneumoniae
challenge. This result provides a rapid and reliable pipeline to achieve
the hyper-production of OmlA, and possibly other recombinant vaccines,
in C. glutamicum.
