Quantifying endothelial cell proliferation in the zebrafish embryo
Authors: Bowley George , Chico Timothy JA , Serbanovic-Canic Jovana , Evans Paul C
Published: October 2021

Introduction: Endothelial cell (EC) proliferation is a fundamental determinant of vascular development and homeostasis, and contributes to cardiovascular disease by increasing vascular permeability to blood-borne lipoproteins. Rodents have been traditionally used to analyse EC proliferation mechanisms in vascular health and disease; however, alternative models such as the zebrafish embryo allow researchers to conduct small scale screening studies in a physiologically relevant vasculature whilst reducing the use of mammals in biomedical research. In vitro models of EC proliferation are valuable but do not fully recapitulate the complexity of the in vivo situation. Several groups have used zebrafish embryos for vascular biology research because they offer the advantages of an in vivo model in terms of complexity but are also genetically manipulable and optically transparent.

Methods: Here we investigated whether zebrafish embryos can provide a suitable model for the study of EC proliferation. We explored the use of antibody, DNA labelling, and time-lapse imaging approaches.

Results: Antibody and DNA labelling approaches were of limited use in zebrafish due to the low rate of EC proliferation combined with the relatively narrow window of time in which they can label proliferating nuclei. By contrast, time-lapse imaging of fluorescent proteins localised to endothelial nuclei was a sensitive method to quantify EC proliferation in zebrafish embryos.

Discussion: We conclude that time-lapse imaging is suitable for analysis of endothelial cell proliferation in zebrafish, and that this method is capable of capturing more instances of EC proliferation than immunostaining or cell labelling alternatives. This approach is relevant to anyone studying endothelial cell proliferation for screening genes or small molecules involved in EC proliferation. It offers greater biological relevance than existing in vitro models such as HUVECs culture, whilst reducing the overall number of animals used for this type of research.
Perceived risk and condomless sex practice with commercial and non-commercial sexual partners of male migrant sex workers in London, UK
Authors: Ruiz-Burga Elisa
Published: October 2021

Background: Since the emergence of HIV and the AIDS pandemic, the majority of risk-reduction interventions have been centred on the use of condoms in sex workers.

Methods: This qualitative study recruited 25 male migrant sex workers in London to understand their risk perception and condomless sex experiences within the context of sex work and private life. The data was collected using face-to-face interviews, analysed using thematic analysis, and the findings interpreted through the theory of planned behaviour.

Results: The themes explain that condomless sex with clients occurred when participants consciously accepted to perform this service deploying a risk assessment of clients, faulty strategies, and sexual practices to reduce their risk; or when they lost control because of recreational drugs, feeling attraction to clients, in precarious circumstances, or were victims of violence. Conversely, condomless sex with non-commercial partners occurred according to the type of relationship, with formal partners it was rationalised through emotional aspects attached to this kind of relationship, while with casual partners it was connected to sexual arousal and the use of alcohol and drugs. 

Conclusions: Reinforce educational interventions to deliver STI-HIV information, enhance the use of condoms, and to address specific contextual factors that facilitate condomless practice with commercial and non-commercial sexual partners.
The Evolutionary Dynamics of the Artificial Intelligence Ecosystem
Authors: Jacobides Michael G. , Brusoni Stefano , Candelon Francois
Published: October 2021

We analyze the sectoral and national systems of firms and institutions that collectively engage in artificial intelligence (AI). Moving beyond the analysis of AI as a general-purpose technology or its particular areas of application, we draw on the evolutionary analysis of sectoral systems and ask, “Who does what?” in AI. We provide a granular view of the complex interdependency patterns that connect developers, manufacturers, and users of AI. We distinguish between AI enablement, AI production, and AI consumption and analyze the emerging patterns of cospecialization between firms and communities. We find that AI provision is characterized by the dominance of a small number of Big Tech firms, whose downstream use of AI (e.g., search, payments, social media) has underpinned much of the recent progress in AI and who also provide the necessary upstream computing power provision (Cloud and Edge). These firms dominate top academic institutions in AI research, further strengthening their position. We find that AI is adopted by and benefits the small percentage of firms that can both digitize and access high-quality data. We consider how the AI sector has evolved differently in the three key geographies—China, the United States, and the European Union—and note that a handful of firms are building global AI ecosystems. Our contribution is to showcase the evolution of evolutionary thinking with AI as a case study: we show the shift from national/sectoral systems to triple-helix/innovation ecosystems and digital platforms. We conclude with the implications of such a broad evolutionary account for theory and practice.
Health concerns with backyard pigs
Authors: Carr John , Smith Jenny
Published: October 2021

The care of pet pigs and pigs in small holdings can be challenging, as pigs are less commonly seen in general veterinary practice. Although, the majority of health problems in pigs require only basic veterinary care. This article discusses the most likely clinical presentations and outlines several of the more serious conditions in pigs, such as the threat posed by infectious diseases such as African swine fever. Effective communication between vets and owners is very important in the care of pigs and this article also highlights how this can be maintained. It is also important to note that members of the Pig Vet Society are always willing to help colleagues through the more difficult cases
Ultrasound-guided blockade of the dorsal nerve of the penis in a Great Dane
Authors: Dagnall Clare , Coss Peter , Bird Alice
Published: October 2021

This report describes an approach to regional anaesthesia of the dorsal nerves of the penis in a Great Dane, as part of an anaesthetic protocol for surgical urethral resection and anastomosis. Bupivacaine (0.5%) was infiltrated around the left and right dorsal nerves of the penis, with ultrasound guidance. The locoregional approach was trans-perineal, with the ultrasound probe orientated at a right angle to the anus, at the level of the ischial symphysis. The described technique provided good visualisation of the urethra and dorsal arteries of the penis. No adverse events relating to the nerve blockade were encountered and no additional analgesia, other than the methadone premedication, was required intra-operatively. The locoregional approach was subsequently repeated on a cadaver using the same technique and, on dissection, demonstrated deposition of injectate next to the target neurovascular bundles. The technique described may provide a simple method of distal penile anaesthesia in the dog, where ultrasound is available.
Using acupuncture to manage wound healing and chronic back pain in a guinea pig
Authors: Green Krissy
Published: October 2021

Acupuncture is being increasingly used in veterinary medicine in the management of wound healing and chronic pain. In this case study, a guinea pig responded to chronic back pain caused by fractures to multiple thoracic vertebral spinous processes and subsequent vertebral luxation, with severe compulsive self-injurious behaviour. This resulted in a large, full thickness skin wound. Wound healing was managed with a combination of support dressings, multi-model analgesia and manual acupuncture. The underlying back pain was initially managed with manual acupuncture and multimodal analgesia, then subsequently successfully managed long term with non-steroidal anti-inflammatories and electroacupuncture.

Published: October 2021

Antidepressant medications are prescribed to treat depression and related psychiatric illnesses. In patients with depression, many categories of drugs are prescribed to treat clinical conditions and comorbidities. Hence, it is essential to screen such patients for potential drug interactions. The study aimed to assess the frequency of potential drug interactions (pDDIs) associated with antidepressant medications administered to the outpatients of the psychiatry department. This cross-sectional investigation was conducted in a psychiatry outpatient setting. Patients satisfying inclusion criteria were screened for pDDIs by reviewing the patients’ electronic case records. All the identified pDDIs were further evaluated using Micromedex database 2.0.A total of 131 eligible patients’ case records were reviewed. The frequency of pDDIs between antidepressants and other psychotropic medications, antidepressants and non-psychotropic medications, antidepressants,tobacco, antidepressants, and ethanol was 48.1%,9.2%, 7.6%, and 3.8%, respectively. Use of more than three medications [RR: 1.5; CI: 1.1-2.1], presence of total [RR: 7.9; CI: 1.1-52.5] as well as psychiatric polypharmacy [RR: 4.8; CI: 1.3-17.9] were identified as predisposing factors of pDDIs.The results of the multiple regression indicated that the model was a significant predictor of pDDIs (F[3, 127]= 6.368, p<0.01, R2 = 0.13). In comparison,psychiatric polypharmacy was the only variable contributing significantly to the model (B = -0.423, p<.05). Nearly fifty percent of patients taking antidepressant medications were found to have the potential for developing drug interactions. Review of treatment charts for psychotropic, non-psychotropic, and non-prescription medications, along with different medical conditions that patients suffer from and the social habits of patients,is essential to identify and resolve potential drug interactions in at-risk patients.

Mode Analysis of Tectorial Membrane in Cochlea
Authors: Kitamura Toshiaki
Published: October 2021

We investigated the dispersion characteristics of the propagation modes that progress on the tectorial membrane (TM). Recent studies have uncovered complex TM behavior and a possibility that TM might play an important role in the hearing system. An interaction between the TM and the fluid induces propagation modes, which are called TM modes. We found that there are several kinds of TM modes and analyzed the direction of the displacement of the TM that is caused by each mode. We also investigated the structural dependency of the angular wavenumber of each mode.

Published: October 2021

Background:Methicillin-resistant Staphylococcus aureus (MRSA) has gained significant health solicitude globallydue to its resistance to nearly almost antimicrobial agents, and garlic is one of nature's most powerful antibiotics that must be used as a pharmaceutical regimen. The current study aimed to determine the In-Vitro antibacterial efficacy of crude garlic extract against MRSA. Methods: The aqueous and 70% ethanol crude garlic (Alllium sativum)extract was prepared. Disc diffusion method was performed to assess the antimicrobial activity for100 clinical isolates of MRSA collected,The reference standard strain was Staphylococcus aureus (ATCC 25923). Results: All MRSA strains assessed were significantly sensitive to 70% ethanolic extract at various concentrations range from 200 to 25%, exhibited inhibitory effects against clinical isolates and Staphylococcus aureus (ATCC 25923) with the means of inhibition zones ranging from 17.76- 14.35 mm and 15-13 mm in length, while the aqueous extracts were less in both clinical isolates and Staphylococcus aureus (ATCC 25923) ranging from 11.93-8.62 mm and 11-8 mm respectively, methanol and distilled water were not effected on growth. Conclusion: The findings demonstrate that 70%ethanol extract of crude Allium sativum has significantly inhibitory effect on methicillin-resistant Staphylococcus aureus is better than aqueous extract. This study does not undermine the value of antibiotic use, but instead the probability of using them in low dosage to minimize their negative consequences.

Published: October 2021

An ultrawide bandwidth and single-mode polarization beam splitter (PBS) based on an air-gap type of dual-hollow-core antiresonant fiber (DHC-ARF) is proposed. Nested tubes are introduced into two cladding tubes between two cores to weaken the wavelength dependence of coupling length in DHC-ARF for obtaining ultrawide bandwidth. By tuning the cladding tube sizes, higher-order core modes with the lowest loss can be coupled with cladding tube modes, and thus, effectively, single-mode operation is achieved. Numerical results demonstrate that an 8.15 cm long DHC-ARF can be used to develop a PBS with an operating bandwidth of 370 nm ranging from 1.28 to 1.65 µm, where a polarization extinction ratio is below

Extracting epsilon-near-zero wavelength of ultrathin plasmonic film
Authors: Dai Xinhai , Wang Heng , Sun Lixun , Meng Chao , Li Shuang , Zhang Wending , Mei Ting
Published: October 2021

Strong optical nonlinearities of plasmonic thin films exist at their epsilon-near-zero (ENZ) wavelengths, which are essential to be acquired first for the design and fabrication of ENZ photonic devices. However, it has been challenging to obtain the ENZ wavelength precisely when the film thickness is reduced to tens of nanometers or less. By enhancing both electric field intensity and light–matter interaction distance in the film, we propose that the ENZ wavelength and the medium model of ultrathin films can be extracted accurately from the transmittance and reflectance spectra under oblique light excitation. A characteristic valley in the transmittance spectrum, which originates from the increased light absorption caused by the ENZ electric field enhancement, can be used to determine the ENZ wavelength with significantly improved fitting accuracy of the Drude parameters. The work in this paper provides an accurate and effective method for the acquisition of ENZ wavelength and will contribute to the research of nonlinear plasmonic devices.
Suppression of motion artifacts in intravascular photoacoustic image sequences
Authors: Sun Zheng , Du Jiejie
Published: October 2021

Intravascular photoacoustic (IVPA) imaging is an image-based imaging modality for the assessment of atherosclerotic plaques. Successful application of IVPA for in vivo coronary arterial imaging requires one overcomes the challenge of motion artifacts associated with the cardiac cycle. We propose a method for correcting artifacts owing to cardiac motion, which are observed in sequential IVPA images acquired by the continuous pullback of the imaging catheter. This method groups raw photoacoustic signals into subsets corresponding to similar phases in the cardiac cycles. Thereafter, the sequential images are reconstructed, by representing the initial pressure distribution on the vascular cross-sections based on the clustered frames of signals by time reversal. Results of simulation data demonstrate the efficacy of this method in suppressing motion artifacts. Qualitative and quantitative evaluations of the method indicate an enhancement of the image quality. Comparison results reveal that this method is computationally efficient in motion correction compared with the image-based gating.

Incorrect endotracheal tube (ETT) cuff inflation pressure causes significant problems for intubated patients. The technical development and first in vivo use of a smart ETT for measurements at the cuff-trachea interface during mechanical ventilation are described. The intra-tracheal multiplexed sensing (iTraXS) ETT contains integrated optical fibre sensors to measure contact pressure and blood perfusion. The device is tested during mechanical ventilation in a porcine model (N=6). For contact pressure, signals were obtained in all 30 measurements. For perfusion, data could be obtained in all 33 measurements. In the 3 cases where the cuff was inflated to an artificially high-level, blood occlusion is observed.

Published: October 2021

Acquired brain injury (ABI), which is the umbrella term for all brain injuries, is one of the most dangerous diseases resulting in high morbidity and mortality, making it extremely significant to early diagnosis of ABI. Current methods, which are mainly composed of X-ray computed tomography and magnetic resonance angiography, remain limited in diagnosis of ABI with respect to limited spatial resolution and long scanning times. Here, we reported through-skull fluorescence imaging of mouse cerebral vasculature without craniotomy, utilizing the fluorescence of down-conversion nanoparticles (DCNPs) in the 1.3 - 1.7 μm near-infrared window (NIR-II window). Due to its high spatial resolution of 22.79 μm, the NIR-II fluorescence imaging method could quickly distinguish the brain injury region of mice after performing the stab wound injury (traumatic brain injury) and ischemic stroke (non-traumatic brain injury), enabling it a powerful tool in the noninvasive and early diagnosis of ABI.
End-to-end learned single lens design using fast differentiable ray tracing
Authors: Li Zongling , Hou Qingyu , Wang Zhipeng , Tan Fanjiao , Liu Jin , Zhang Wei
Published: October 2021

In traditional imaging system design, the optical lens is often optimized toward the artificial optimization target like modulation transfer function and field-of-view (FoV). This usually leads to complex stacks of lenses. In order to reduce the complexity, we propose an end-to-end single lens imaging system design method. First, the imaging and processing model is established, whose input end is the ground truth image, and the output end is the restored image by Res-Unet. Then, with the optimization target of minimizing the difference between the restored image and the ground truth image, the parameters of the lens surface and the parameters of the restoration algorithm are optimized simultaneously by deep learning. In order to realize the end-to-end design, the imaging model is required to be differentiable to the lens parameters, so a fast differentiable ray tracing model is proposed. A single lens imaging system with high-quality large FoV (47°) has been designed by the end-to-end method. This method will have a wide application prospects in the design of light and small optoelectronic imaging systems.

Published: October 2021

Digitales Lernen ist ein zentraler Bestandteil der heutigen Bildungslandschaft geworden. Insbesondere Lernvideos haben in den letzten Jahren deutlich an Popularität gewonnen und Plattformen wie YouTube sind heute ein fester Bestandteil von Lernprozessen. Bildungseinrichtungen haben diese Entwicklung erkannt und Lernvideos in ihre Lernsysteme integriert. Allerdings sind die heutigen Lernvideos oft nicht sehr ansprechend, weil es an Gestaltungswissen mangelt, wie Interaktionen und gamifizierte Elemente die Motivation und den Lernerfolg steigern können. Dieser Mangel an Gestaltungswissen führt zu minderwertigen Lernvideos, die den Lernprozess der Lernenden meist nicht in dem Maße unterstützen, wie sie es könnten. Um effektive Lernvideos zu entwickeln, welche die Lernenden adäquat unterstützen, ist handfestes und praktisches Gestaltungswissen für die Lehrenden notwendig. Vor diesem Hintergrund entwickeln wir Entwurfsmuster für interaktive gamifizierte Lernvideos, um Praktiker*innen bei der Erstellung effektiver Lernvideos anzuleiten, die die Motivation und das Engagement von Lernenden zu fördern, welche sie aktiv in ihrem Lernprozess unterstützen zu können. Wir setzen damit zusätzlich die Grundlage für zukünftige Forschung zur Gestaltung effektiver Lernvideos. Dabei folgen wir einem gestaltungsorientierten Forschungsansatz, um die Entwicklung unserer Entwurfsmuster zu systematisieren.
Prevalence and associated factors of malaria in children under the age of five years in Wogera district, northwest Ethiopia: A cross-sectional study
Authors: Tsegaye Adino Tesfahun , Ayele Andualem , Birhanu Simon
Published: October 2021

Background

Malaria is a major public health problem in sub-Saharan Africa, and children are especially vulnerable. In 2019, an estimated 409,000 people died of malaria, most (274,000) were young children and 94% of the cases and deaths were in Africa. Prior studies in Ethiopia focused on the adult population and high transmission areas. Hence, this study aimed to determine the prevalence and associated factors of malaria in children under five years in low transmission areas.

Method

A facility-based cross-sectional study was conducted among 585 under-five children who attended public health facilities in the Wogera district from September to October, 2017. Health facilities were selected by stratified cluster sampling, and systematic random sampling was held to select study participants from the selected facilities. Multivariable logistic regression was used to identify correlates of malaria.

Result

Of 585 children who provided blood samples, 51 (8.7%) had malaria. The predominant Plasmodium species were P. falciparum 33 (65%) and P. vivax 18 (35%). Regularly sleeping under long-lasting insecticide treated nets (LLIN) was associated with decreased odds of malaria (AOR = 0.08, 95% CI: 0.01–0.09), and an increased odds of malaria was observed among children who live in households with stagnant water in the compound (AOR = 6.7, 95% CI: 3.6–12.6) and children who stay outdoors during the night (AOR = 5.5, 95% CI: 2.7–11.1).

Conclusion

The prevalence of malaria in the study population was high. Environmental and behavioral factors related to LLIN use remain potential determinants of malaria. Continued public health interventions targeting proper utilization of bed nets, drainage of stagnant water, and improved public awareness about reducing the risk of insect bites have the potential to minimize the prevalence of malaria and improve the health of children.

The unprecedented growth of educated workforce following the economic development and diversity in workplace has widened the career choices of young people in Bangladesh. However, it intensifies a dilemma among the job seekers about determining their career goals, because career goals are often influenced by certain socio-demographic and cultural aspects. Hence, this cross-sectional study was designed to investigate the career choices of university students in Bangladesh and to identify its determinants. Administering a self-administered questionnaire (SAQ), data were collected from 422 students at a public university using the multistage stratified sampling. Data were analyzed by bivariate (chi-square) and multivariate (exploratory factor analysis and binary logistic regression) analyses. Findings suggest that the career choices of students vary regarding their gender, religion, and academic track. For example, female (AOR: 0.281; 95% CI: 0.144 to 0.547) and Muslim (AOR: 3.648; 95% CI: 1.765 to 7.542) students preferred public jobs, whereas students of commerce (AOR: 0.344; 95% CI: 0.144 to 0.820) went for private ones. Among socioeconomic issues, only the father’s occupation had a substantial effect on career decisions (AOR: 0.347; 95% CI: 0.144 to 0.820). The career choice was also determined by the job prospects (AOR: 1.251; 95% CI: 1.161 to 1.347), preference of family (AOR: 1.238; 95% CI: 1.099 to 1.394), as well as job diversity (AOR: 0.879; 95% CI: 0.795 to 0.972). Based on the findings of this study, it is recommended that the government should address the trends and patterns of career choices of students through empirical research when formulating future educational and career-related policies in Bangladesh.

In France, social distancing measures have been adopted to contain the spread of COVID-19, culminating in national Lockdowns. The use of hand washing, hydro-alcoholic rubs and mask-wearing also increased over time. As these measures are likely to impact the transmission of many communicable diseases, we studied the changes in common infectious diseases incidence in France during the first year of COVID-19 circulation. We examined the weekly incidence of acute gastroenteritis, chickenpox, acute respiratory infections and bronchiolitis reported in general practitioner networks since January 2016. We obtained search engine query volume for French terms related to these diseases and sales data for relevant drugs over the same period. A periodic regression model was fit to disease incidence, drug sales and search query volume before the COVID-19 period and extrapolated afterwards. We compared the expected values with observations made in 2020. During the first lockdown period, incidence dropped by 67% for gastroenteritis, by 79% for bronchiolitis, by 49% for acute respiratory infection and 90% for chickenpox compared to the past years. Reductions with respect to the expected incidence reflected the strength of implemented measures. Incidence in children was impacted the most. Reduction in primary care consultations dropped during a short period at the beginning of the first lockdown period but remained more than 95% of the expected value afterwards. In primary care, the large decrease in reported gastroenteritis, chickenpox or bronchiolitis observed during the period where many barrier measures were implemented imply that the circulation of common viruses was reduced and informs on the overall effect of these measures.
Streaming platforms’ contribution to capitalization of local audio-visual producers in Mexico and Canada
Authors: Muñoz Larroa Argelia
Published: October 2021

This article examines the contribution of streaming platforms in providing financial investment – in the form of co-productions, commissions and acquisitions of audio-visual content – as well as capital returns to local audio-visual producers. It will focus on the North American region, particularly on Mexico and Canada, as gravitating around stronger US audio-visual companies. Studies of traditional audio-visual windows in the countries studied have pointed out the undercapitalization of independent content producers due to financial structures and capital return models that are disadvantageous to them. This article questions: what is streaming’s contribution, as a new commercialization window, to the capitalization of local independent producers? The research conducted a qualitative study of interviews with film producers and distributors as well as an industrial analysis based on previous studies, media and business reports. The research has found that streaming tends to provide: (1) equal or slightly less returns than what the DVD window used to offer; and (2) equal or more generous figures than those delivered by TV and cinema exhibition windows. Furthermore, streaming has promoted a burgeoning production activity – adding to the production from traditional players (film and TV). These are benefits that should not be overlooked. However, streaming has not altered independent producers’ disadvantageous position: (1) revenue shares are still relatively small; (2) licences represent small percentages of what content costs to make; (3) commissioning and co-production budgets are fairly close to production costs; and (4) the boom of platforms’ original production is actually a battle among large corporations to control intellectual property (IP). All the above keep hindering the financial capacity of local independent producers.

The first part of the study introduces the various interpretations of liquidity and gives a detailed description of the adjustments that need to be made on accounting data for an a posteriori examination of liquidity and to be able to forecast liquidity. The second part discusses the possible means and tools of analysis, including the differences between static and dynamic methods and the calculation and interpretation of the various ratios widely used by professionals. The conclusion is that there is no best-practice method or ratio, but rather a wide range of tools is to be used when one is willing to gain a complex and comprehensive insight about an entity’s liquidity.
Fenntarthatóság a hazai vállalati gyakorlatban – A „Versenyben a világgal” kutatási program 2009. évi kérdőíves felmérés eredményeinek vizsgálata (Sustainability in the practice of Hungarian firms)
Authors: Bárth-Fehér Szilvia
Published: October 2021

A fenntarthatóság kérdésköre napjainkban egyre inkább a figyelem középpontjába kerül. Egyes szerzők egyenesen a következő, a minőségi és az információs forradalomhoz hasonló megatrendnek tartják a fenntarthatóságot (Lubin – Esty, 2010). A tanulmány célja megvizsgálni, mennyiben érvényesül ez a megatrend Magyarországon: mennyiben kezelik stratégiai, versenyképességi kérdésként a magyar vállalatok a környezetvédelmet és a fenntarthatóságot? A szerző tanulmányában bemutatja a fenntartható fejlődés vállalati vonatkozásait, majd megvizsgálja, mennyiben jelennek meg a hazai vállalatok stratégiájában és gyakorlatában a fenntarthatóság aspektusai. Az elemzéshez a Budapesti Corvinus Egyetem Versenyképesség Kutató Központjában 2009-ben lebonyolított kérdőíves felmérés adatait használta fel. _______ Sustainability has been receiving an ever increasing attention in recent years. Some authors even cite sustainability as the next megatrend after quality and IT revolutions (Lubin–Esty, 2010). This paper aims to examine to what extent this megatrend prevails in Hungary: do Hungarian companies treat environmental protection and sustainability as a strategic element of competitiveness? The paper studies the concept of corporate sustainability, then examines the presence of the three aspects of sustainability in the strategy and practice of Hungarian firms. The analysis is based on the results of a survey on competitiveness carried out by the Competitiveness Research Centre of Corvinus University of Budapest in 2009.

Panel fotovoltaico de 10 W diseñado usando Comsol multiphysics
Authors: Velásquez-Garzón Michael Jair , Aguilar-Arévalo David Alejandro , Puin-Ávila Harold David
Published: October 2021

En la actualidad, la energía solar constituye la segunda fuente de energía renovable de mayor aprovechamiento en el mundo, por lo que se ha progresado en la eficiencia y reducción de área de impacto de paneles solares. No obstante, aun, en comparación con otras fuentes de energía eléctrica, su costo de adquisición sigue elevado en implementaciones de alta potencia. En el presente artículo, mediante el software COMSOL Multiphysics -utilizando elementos finitos-, se simula y analiza una de las celdas de un panel solar fotovoltaico de 10(W). Se realizan pruebas en periodos distintos de tiempo y con intensidad de radiación solar diferentes, identificándose curvas características adquiridas de corriente vs tensión, y potencia vs tensión. Se evalúan, por comparación, los datos arrojados con respecto a los dados por el fabricante encontrándose plausibles dado un error relativo admisible de 1,428% y 1,639%, respectivamente. Como el comportamiento del panel solar depende en gran parte de la radiación solar proyectada en él, y de la temperatura ambiente, se evidencia que a mayor radiación solar sobre el panel la corriente demandada capaz de otorgar aumenta.

Diabetes melitus merupakan penyakit kelainan metabolic yang ditandai dengan hiperglikemia kronis yang disebabkan tidak cukupnya produksi insulin dan resistensi insulin. Diabetes telah diketahui dapat menyebabkan komplikasi berupa kerusakan pada jaringan ginjal. Mimba (Azadirachta indica A.Juss) memiliki kandungan antioksidan flavonoid yang mampu menangkal radikal bebas dan memperbaiki jaringan ginjal yang rusak akibat diabetes. Penelitian ini menggunakan 18 tikus putih yang menjadi 6 kelompok perlakuan. P0 (kontrol normal) merupakan tukus normal diberi aquades. P1(Kontrol negatif) merupakan tikus hiperglikemia diberi aquades. P2 (kontrol positif) merupakan tikus hiperglikemia diberi glibenklamid dosis 2,25 mg/ kg BB. P3, P4, dan P5 merupakan tikus hiperglikemia yang diberi ekstrak etanol daun mimba dosis 100, 200, dan 400 mg/kg BB. Data penelitian kemudian dianalisis dengan uji Anova. Untuk data yang tidak terdistribusi normal diuji dengan uji Kruskal-Wallis. Hasil menunjukkan bahwa pemberian ekstrak etanol daun mimba tidak memberikan pengaruh nyata terhadap bobot ginjal, konsumsi air minum, diameter glomerulus, ruang kapsula bowman, tebal sel epitel tubulus proksimal, dan tebal sel epitel tubulus distal. Kesimpulan dari penelitian ini adalah ekstrak etanol daun mimba  mampu melindungi jaringan ginjal tikus putih dari paparan hiperglikemia Diabetes is  a metabolic disorder that treats chronic hyperglycemia caused by insufficient insulin production and insulin resistance. Diabetes has been  known to cause complications in the form of damage to kidney tissue. Neem (Azadirachta indica A.Juss) has flavonoid antioxidants that can ward off free radicals and repair kidney tissue damaged by diabetes. The purpose of the study was to examine the ethanol extract of neem leaves repairing kidney tissue. The study used 18 albino rats were divided into 6 treatment groups. P1 (negative control) was a hyperglycemic rats group were given distilled water. P2 (positive control) was a hyperglycemic rats were given 2.25 mg/kg BW of glibenclamide. P3, P4, and P5 were rats were given 100, 200, and 400 mg/kg BW of ethanolic neem leaf extract The research data were analyzed by ANOVA. The non-normally distributed data were analyzed by  Kruskal-Wallis. The results showed that the ethanol extract of neem leaves had no significant effect on kidney weight, water consumption, glomerular diameter, bowman's capsule space, proximal tubular epithelial cell thickness, and distal tubular epithelial cell thickness. The conclusion of this study was  the ethanol extract of neem leaves  was able to protect the kidney tissue of white rats from hyperglycemia.
