Hope, Solidarity, and Justice
Authors: Stockdale Katie
Published: June 2021

This article defends an account of collective hope that arises through solidarity in the pursuit of justice. I begin by reviewing recent literature on the nature of hope. I then explore the relationship between hope and solidarity to demonstrate the ways in which solidarity can give rise to hope. I suggest that the hope born of solidarity is collective when it is shared by at least some others, when it is caused or strengthened by activity in a collective action setting, and when the reciprocal hopeful expressions of individual group members result in an emotional atmosphere of hope that extends across the group. In the context of social movements, collective hope emerges alongside the collective intentions and actions of the solidarity group; namely, in the pursuit of a form of social justice that inspires the movement. I then suggest that the object of collective hope born of solidarity is the guiding ideal of justice and reflect on what it might mean to hope well for justice.
Soluciones de las comunidades autónomas de régimen general a algunas deficiencias de la Ley 49/2002 de Régimen fiscal de las entidades no lucrativas en el ámbito del mecenazgo cultural
Authors: Palacios Ronda Esteban
Published: June 2021

La vigente Ley 49/2002 de Régimen fiscal de las entidades no lucrativas y de los incentivos fiscales al mecenazgo nació con la voluntad declarada de establecer un conjunto de estímulos aplicables a la actividad de mecenazgo en general y al cultural en particular. Sin embargo, la aplicación práctica de este principio inspirador se revela en la actualidad como una mera proposición normativa. Por su parte, las comunidades autónomas de las Islas Baleares, Comunidad Valenciana y Castila-La Mancha han promulgado sendas leyes de incentivos fiscales al mecenazgo cultural que podrían resolver en el ámbito de sus competencias algunas dificultades de que adolece la norma estatal. Con estos antecedentes analizaremos el alcance efectivo de las medidas fiscales autonómicas en sede de la imposición sobre la renta y su conexión con el régimen fiscal general del mecenazgo lo que, tras detenernos en alguna de las deficiencias advertidas, nos permitirá apuntar algunas propuestas de reforma del régimen fiscal del mecenazgo, considerado en su conjunto, que permita romper la actual estanqueidad normativa.
Increasing the efficiency of blast-furnace smelting by improving the quality of iron ore materials
Authors: Nesterov A.S. , Garmash L.I.
Published: June 2021

It is noted in the work that when mastering the technology of pulverized
coal injection (PUT) at the metallurgical enterprises of Ukraine, it is necessary to
intensify work, including research, in the direction of improving the quality
characteristics of the sinter, the stability of its chemical composition and strength
parameters. The analysis of the quality of iron ore raw materials used in sintering
production in Ukraine and foreign countries is carried out. The requirements of
international and domestic standards for the quality of raw materials and fuels, providing
for the injection of large quantities of firearms into the furnace, are given. A
methodology for determining the quality of raw materials developed in the HMI is
described. The results of a study of the quality of iron ore raw materials according to the
developed method are presented. Based on the analysis of the results of the research,
requirements were developed for the quality of granular iron ore wastes and their
rational amount in the composition of the sinter charge, and the process for the
production of granules was developed. Recommendations have been developed on the
use in the sinter mixture of a part of the granular components of secondary waste, which
allowed to increase the content of secondary resources in the mixture. As a result, the
chemical composition of the sinter was stabilized, its strength was improved, the yield of
sinter of the second grade was reduced, the removal of blast furnace dust and coke
consumption were reduced. Improving the quality of the sinter and the rational
distribution of charge materials over the cross-section of the top of the blast furnace
allows for self-renewal of the protective skull, to reduce the removal of top dust by 4.3
kg / t of cast iron, and to reduce coke consumption by 19.6 kg / t of cast iron. The
developed measures make it possible to increase the competitiveness of products, even
at the additional cost of preparing the sinter mixture for sintering.
Teaching assimilations to improve listening skills for Vietnamese students
Authors: Tran Du Thanh
Published: June 2021

Few would deny that at the very first stage of learning, language learners have to spend most of their time on practising listening skills in communication inside and outside class. They have to listen to others speaking, listen to themselves while talking and even implicitly while reading and writing. Listening is an important way of acquiring the language as well as picking up the structures and vocabulary. With a careful observation of the current situation of Vietnamese learners’ listening competencies and a thorough review of reference materials in English language teaching and learning, it is hoped that the study will help heighten students’ awareness of the problematic sounds that they encounter when listening to colloquial, casual and connected speech.

Authors: Rahman M. Moshiur , Rahman M. Mizanur , Mian M. Abdul Khaleque , Islam M. Ariful
Published: June 2021

A multi location trial with five promising strawberry genotypes viz., Sweet Charlie, Festival, Camarosa, FA 008 and BARI Strawberry-1 was conducted under different sub tropical climatic conditions of Bangladesh to study their G ´ E interaction. Location were Gazipur, Rajshahi and Chittagong during the period from August 2009 to May 2011. Combined analysis of variance indicated significant variation among the genotypes as well as location for almost all the characters studied. Genotype ´ environment studies indicated different response of genotypes over locations for most of the characters suggesting location wise environmental variation. Stability parameter revealed that a particular genotype did not perform consistently for all the characters. The genotype Festival considered as stable for most of the characters except days to flowering and ascorbic acid content of fruits, and considered as stable over different locations. For this reason, the genotype Festival could be well thought-out and less receptive to the environmental conditions and might be recommended for all environments. On the other hand, environmental indices indicated that the environment of Rajshahi was found to be most favourable for strawberry cultivation followed by that of Gazipur and Chittagong.

Authors: Rehman Asim , Nawaz Muhammad , Chughtai Arshad , Butt Muhammad Arif , Sattar Abdul
Published: June 2021

In this study, a new prospective regarding application of gas liquid reactions in the presence of catalyst was studied for pollution abatement in the novel reactor. Catalytic hydrodechlorination (CHDC)of 2,4-dichlorophenol (2,4-DCP) in aqueous system was carried out under the operating conditions at 25- 75 °C, 1 atm in co-current down flow contactor reactor. Under these reaction conditions complete conversion  of 2,4-DCP into less toxic products (phenol and cyclohexanone) was achieved using 5% Pd/C catalyst. At typical temperature the hydrodechlorination reaction of 2,4-DCP was completed after 10 min. 2,4-DCP was converted to 96.19% of phenol and 3.81% of cyclohexanone using 0.4 g/L of 5% Pd/C catalyst. The increase in initial concentration of 2,4-DCP resulted in the increase in time for the dechlorination of 2,4- DCP. The calculated activation energy values amounted to 43 KJ/mol for the CHDC of 2,4-DCP exhibiting that this reaction occurs mainly under the surface reaction rate controlled condition.

Published: June 2021

Performance of injection moulded short wollastonite fibre and chopped glass fibre reinforced hybrid epoxy composites was studied. The results showed that hybridisation of glass fibre and wollastonitewas in congruence to epoxy glass fibre composite system. Effect of fibre length, fibre orientation in matrix and analysis and fracture surface was undertaken. The mechanical properties of injection moulded, chopped glass fibre/wollastonite/epoxy hybrid composites were investigated by considering the effect of hybridisation by these two fillers. It was observed that the tensile, flexural, and impact properties of the filled epoxy were higher than those of unfilled epoxy. The effect of filler on epoxy matrix subjected to the tensile strength and modulus was studied and compared with the rule of mixture. The actual results are marginally low as compared with the values obtained by the rule of hybrid mixtures (RoHM).
Manufacturing of Kevlar/Polyester Composite by Resin Transfer Moulding using Conventional and Microwave Heating
Authors: Abdullah Iram
Published: June 2021

Microwave heating was incorporated into the resin transfer moulding technique. Polytetrafluoroethylene (PTFE) mould was used to cure the composite panel. Through the use of microwave heating, the mechanical and physical properties of produced Kevlar fibre/polyester composites were compared to those manufactured by conventional resin transfer moulding. The flexural modulus and flexural strength of 6-ply conventionally cured composites was 45% and 9% higher than the flexural modulus and flexural strength of 6-ply microwaved cured composites, respectively. However, 19% increase in interlaminar shear strength (ILSS) and 2% increase in compressive strength was observed in 6-ply microwave cured composites. This enhancement in ILSS and compressive strength is attributed to the better interfacial bonding of polyester resin with Kevlar fibres in microwaved cured composite, which was also confirmed via electron microscopy scanning. Furthermore, the microwave cured composite yielded maximum void contents (3%).
SN2 Mechanism of Cationic Micelles on the Hydrolysis of Bis-p-Methoxyphenyl Phosphate Ester
Authors: Kumar Abanish
Published: June 2021

Hydrolysis of bis-p-methoxyphenyl phosphate ester (bis-p-MPPE) was studied in micellar solutions of cityltrimethylammoniumbromide n-C16H33N+(CH3)3Br- (CTABr) at pH-9.0. The hydrolysis followed first order kinetics with respect to bis-p-MPPE concentration. At the concentration of critical micelle concentration (CMC) the rate of hydrolysis increased with increasing CTABr concentration. Surfactant with cationic or polar head group form micelles in water with hydrocarbon like interior or polar groups at the surface and bind cationic solute. The binding constant of micelle for bis-p-MPPE and the rate constant in micellar pseudo phase were determined from kinetic data using the pseudophase model.

Published: June 2021

Effect of heat treatment on yield and some quality parameters of loofah seed (Luffa cylindrica Linn.) oil was the focus of this study. Central composite rotatable response surface methodology design for two variables was used for this investigation. Fatty acid composition of the un-treated oil was determined. The independent variables roasting temperature were 102, 110, 130, 150, 158 °C and duration 16, 20, 30, 40, 44 min while oil yield, moisture content, free fatty acid, colour, refractive index and specific gravity of the oil were the dependent variables. All determinations were done using standard methods. Linoleic acid  (50.66%), oleic acid (27.66%), palmitic acid (12.28%) and stearic acid (6.44%) were the major fatty acids. Mean oil yield, moisture, free fatty acid, colour, refractive index and specific gravity were 25.91±5.16%,0.035±0.003%, 5.3±2.47%, 15.23±1.83 mg/100g, 1.47±0.002 ND40  and 0.913±0.02, respectively. All the parameters were significantly affected by heat treatment (p<0.05). Regression models were not fit to expressthe relation, thus optimisation using response surface approach was not adequate.

Authors: Huang Zhongqiang , Zhang Ping , Liu Ruigang , Li Dongxu
Published: June 2021

The identification of immature apples is a key technical link to realize automatic real-time monitoring of orchards, expert decision-making, and realization of orchard output prediction. In the orchard scene, the reflection caused by light and the color of immature apples are highly similar to the leaves, especially the obscuration and overlap of fruits by leaves and branches, which brings great challenges to the detection of immature apples. This paper proposes an improved YOLOv3 detection method for immature apples in the orchard scene. Use CSPDarknet53 as the backbone network of the model, introduce the CIOU target frame regression mechanism, and combine with the Mosaic algorithm to improve the detection accuracy. For the data set with severely occluded fruits, the F1 and mAP of the immature apple recognition model proposed in this article are 0.652 and 0.675, respectively. The inference speed for a single 416×416 picture is 12 ms, the detection speed can reach 83 frames/s on 1080ti, and the inference speed is 8.6 ms. Therefore, for the severely occluded immature apple data set, the method proposed in this article has a significant detection effect, and provides a feasible solution for the automation and mechanization of the apple industry.

Recently, deep learning has been successfully applied to robotic grasp detection. Based on convolutional neural networks (CNNs), there have been lots of end-to-end detection approaches. But end-to-end approaches have strict requirements for the dataset used for training the neural network models and it’s hard to achieve in practical use. Therefore, we proposed a two-stage approach using particle swarm optimizer (PSO) candidate estimator and CNN to detect the most likely grasp. Our approach achieved an accuracy of 92.8% on the Cornell Grasp Dataset, which leaped into the front ranks of the existing approaches and is able to run at real-time speeds. After a small change of the approach, we can predict multiple grasps per object in the meantime so that an object can be grasped in a variety of ways.

Deliberate poisoning with intentional ingestion of elemental mercury is reported not to result in systemic toxicity due to minimal absorption from the gastrointestinal tract. We report a case of a 43 year old male who intentionally ingested 200ml elemental mercury which resulted in abdominal pain and vomiting. The patient subsequently aspirated globules of mercury which was confirmed on chest x-ray and his blood mercury levels were markedly raised. He was treated with chelating agents and managed in a negative pressure room to reduce the risk of staff being exposed to exhaled mercury vapour from the patient.

Published: June 2021

Introduction: First dose intravenous antimicrobial therapy should be administered within 1 hour of admission but this is achieved in a minority of patients.. Methods: We performed a retrospective analysis at the largest Oncology hospital in Europe. Nurse-led administration of initial antibiotic therapy was introduced to the admissions unit. Results: The nurse led protocol increased compliance with the 1 hour target from 40% to 88.6%. There was a statistically significant decrease in the mean length of stay (p=0.045) which was more pronounced in the neutropenic population (p=0.006). There was a trend to improved 30 day mortality. Conclusions: A nurse led protocol can be effective in improving compliance with the 1 hour target. Early administration of intravenous antibiotics in cancer patients with sepsis is associated with a shorter length of inpatient stay and a trend to decreased mortality.

The use of point of care ultrasound (POCU) is increasing across a number of specialties, becoming mandatory within some specialist training programmes (for example respiratory and emergency medicine). Despite this, there are few data looking at the prevalence of use or the training clinicians have undertaken; this survey sought to address this. It shows that the majority of POCU undertaken on the Acute Medical Unit (AMU) is without formal accreditation, with significant barriers to training highlighted including a lack of supervision, time and equipment. For those who undertook POCU, it was shown to regularly speed up clinical decision making, while 76.3% respondents believed a lack of access to POCU out of hours may affect patient safety. The data provide support to the concept of developing AMU specific POCU accreditation, to ensure robust and safe use of this modality on the AMU.

Introduction: Sepsis is one of the most frequent reasons for referral to emergency departments (EDs) worldwide. Sepsis becomes more serious when left untreated with a high mortality rate, exceeding even those of myocardial infarction and stroke. Therefore, much effort has been put in to start with appropriate therapy as early as possible. Emergency medical services (EMS) personnel have already made a significant difference in improving care for patients with acute coronary syndrome, multiple trauma and stroke. Patients with severe sepsis or septic shock could also benefit from timely prehospital care. Earlier recognition and initiation of treatment by EMS personnel may improve survival of these critically ill patients. Methods and analysis: The Prehospital Antibiotics against Sepsis (PHANTASi) trial is an investigator- initiated, multicentre, randomized controlled open-label clinical trial nested within a step wedge design. This study compares the effects of usual care to that of training EMS personnel in recognizing and initiating treatment in the prehospital setting together with early administration of antibiotics for patients suspected of (severe) sepsis and septic shock. Primary outcome is 28 day mortality. Secondary outcomes include, length of hospital stay and admission to intensive care units. Ethics and dissemination: This study has been approved by the research ethics committee of VU University Medical Centre, Amsterdam, The Netherlands (Protocol 2013.458/ NL 42001.029.13). The results of the study will be disseminated at several research conferences and international peer reviewed journals. The study will be implemented and reported in line with the CONSORT statement.

Older people form a growing proportion and volume of those accessing urgent care. Non-specific presentations, multiple comorbidities and functional decline make assessment and management of this cohort challenging. Comprehensive Geriatric Assessment offers an evidence based framework to assess and mange older people, especially those with frailty. In this article we describe the CGA approach, underpinned by specific examples illustrating some of the key competencies required, and describe the role of the Acute Frailty Network (AFN). The AFN is a national improvement collaborative designed to support hospitals in delivering evidence based care for older people with frailty and urgent care needs. We describe the principles underlying the approach of the AFN, derived from working with over 20 hospitals, and some of the early successes.

Uso de agentes antimicrobianos como solução refrigerante no ultrassom para tratamento das doenças periodontais: uma revisão de literatura
Authors: Cardoso Matheus Völz
Published: June 2021

Objetivo: revisar a literatura quanto ao uso de soluções no reservatório líquido do ultrassom (US) para o tratamento das doenças periodontais, avaliando as contribuições dessa associação e as soluções mais eficazes para essa terapêutica. Métodos: foi realizada pesquisa bibliográfica nas bases de dados Public Medline (PubMed), Lilacs, Science Direct e ISI web of knowledge. As palavras-chave utilizadas foram: “periodontal disease”, “ultrasonic”, “cooling solution”, “antimicrobial” e “irrigation”. Como critérios de inclusão, foram selecionados estudos prospectivos, retrospectivos, caso controle, transversal e relatos de casos, publicados em inglês. Resultados: após pesquisa e minuciosa revisão por título e resumo de cada estudo, 15 estudos foram selecionados para avaliação dos desfechos investigados. As principais soluções associadas ao US foram povidono-iodo (PVPI), clorexidina, óleos essenciais, bicarbonato de sódio. O irrigante mais utilizado foi o PVPI, seguido por clorexidina e óleos essenciais. Os agentes podem conferir discretas melhoras no nível clínico de inserção e profundidade de sondagem, porém os resultados são controversos, já que nem todos os ensaios demonstraram efeitos positivos. Uma importante evidência observada foi em relação à redução dos níveis de microrganismos derivados do aerossol do US quando essas substâncias foram utilizadas no reservatório de água, sendo esse um aspecto positivo de seu uso como solução refrigerante ao US. Considerações finais: de modo geral, não puderam ser confirmados benefícios adicionais dos irrigantes antimicrobianos nos principais parâmetros periodontais avaliados, porém não se pode descartar o potencial uso desses agentes para a redução da dispersão de microrganismos advindos do aerossol, promovendo assim maior proteção ao paciente e ao profissional.

En Nicaragua la falta de información sociodemográfica actualizada a nivel de ciudades, municipios, territorios, comunidades, sectores y barrios constituye una limitante para la realización de estudios sobre las características de desarrollo local y territorial y así proponer acciones basadas en evidencias que sean más eficientes y que contribuyan al bienestar de la sociedad, aun cuando los actores institucionales existentes en los territorios tengan claro lo que desean. Esta investigación tuvo como objetivo caracterizar la economía del municipio de León desde la perspectiva planteada por Rodríguez (2015), respecto a las dimensiones de innovación y de interrelación de los sectores económicos del municipio (Modelo Sectorial-Territorial). El estudio se basó en la teoría del desarrollo endógeno, utiliza la clasificación sectorial propuesta por el Instituto Nacional de Información de Desarrollo (INIDE) el cual propone 10 sectores económicos y tiene un enfoque cuantitativo, dado que se realizaron 20 entrevistas a informantes calificados y actores económicos locales para posteriormente cuantificar sub índices e índices propuestos por el modelo, e identificar si el municipio se clasifica en Desarrollo Bajo DB, Desarrollo Defensivo DD, Desarrollo Sectorial DS o Desarrollo Territorial DT. Los resultados muestran que el 50.8% del empleo formal se encuentra concentrado en sectores con DS (industria manufacturera, financiero, electricidad, gas y agua, agricultura, ganadería) el 36.5% en sectores de Desarrollo Defensivo (servicios comunales, sociales y personales, hoteles y restaurantes) y el 12.7% en sectores con Desarrollo Bajo (pesca, minas y canteras, comercio al por mayor y por menor, transporte, almacenamiento y comunicaciones). Finalmente, la economía de León se encuentra en DB (1.56,1) con perspectiva a trasladarse hacia un DD, el cual concentra el empleo formal en actividades con altos niveles de innovación pero con poca relación importante con el resto de la economía local.

Published: June 2021

This research’s objectives were to assess the risk factors associated with ovarian disorders in dairy cattle in Hanoi Capital, Ha Nam Province, Vinh Phuc Province, and Moc Chau District in Son La Province. The ovarian diseases were evaluated by rectal palpation combined with information collected based on the questionnaire and surveys. Records of feeding management and ovarian disorders were comprising of persistent corpus luteum (PCL), cystic ovarian disease (COD), inactive ovary (IO) from 818 females, including heifers and cows from the first to the eighth parities. A multinomial logistic regression procedure in SAS9.0 was applied for data analysis. The results have shown that the changes of region, age classes, housing condition, and body condition scores were associated with the odds of suffering from dairy cattle’s ovarian disorder categories. The cows got the odds of suffering from PCL in the old age or fatter condition, and IO at the younger or angular cows. When cattle were confined in simple houses or laid on rubber bedding, they suffered from IO, but they tended to get the odds of suffering from PCL when the cattle were raised in modern houses or laid on concrete bedding. In conclusion, region, parity, body condition score, housing type, and bedding material affect ovarian disorders in dairy cattle in northern Vietnam.

Published: June 2021

The study was conducted to estimate factors affecting the information sources and communication channels that were used by pig farmers to access information about African Swine Fever (ASF) in Tra Vinh Province, Vietnam, and to determine the perception of pig farmers about ASF epidemic. The survey used the questionnaires to gather data from 150 pig farmers which was conducted in a purposive method and was analyzed by multiple logistic regression model. The respondents were pig farmers who had experienced at least one year and have been affected by ASF epidemic in raising or trading pigs and other activities of the value chain. The result showed that the decision to choose information from government extension worker as the main information resource was affected by gender, pig herd size, informal education, and formal education (p<0.01) while only gender and education affecting the choice of farming visit as their communication channel (p<0.01). When farmers can access to ASF information, they know how to anticipate the disease and deal with the outbreak. It was concluded that socio- demographic have affected the choice of information sources while only gender and formal education affected communication channels. Furthermore, when accessing information sources and communication channels, pig farmers had an awareness of basic information about ASF.
Untangling Decision Routes in Moral Dilemmas: The Refugee Dilemma
Authors: Barque-Duran Albert , Pothos Emmanuel M.
Published: June 2021

It is sometimes considered that there are 2 routes to moral choice, deontological and utilitarian (with debate as to whether each of these routes uniquely reflect emotional vs. analytic components). Yet in moral judgments we are often faced with a third route to choice, based on rules imposed by an outside agency (most typically the legal framework of a country). Whether we agree with these rules or not, we can choose to guide moral choice in this way. Moreover, depending on the situation, we can sometimes choose to prioritize such external rules or not. Sometimes external rules coincide with either deontological or utilitarian biases. But what happens when they do not? Using a novel paradigm for moral judgment, the refugee dilemma, we provide evidence for such a route to moral choice based on external rules. We show in 3 experiments that participants with high scores on a cognitive reflection test or under cognitive load were more likely to adopt utilitarian or rule-based responses, as opposed to emotional ones. We also found that rule-based respondents reported the highest average psychological distance. These findings extend the predominant approach of dual process models.

Horror Videogame Sound Effects, Cardiovascular Arousal, and Ethnic Bias in the Decision to Shoot
Authors: Ballard Mary E. , Spencer Michael , Holtkamp Megan K. , Sakrison Evan , Kindle Ta’rah
Published: June 2021

This study used a survival horror videogame to examine the impact of scary sound effects on cardiovascular and affective arousal and determine whether differences in cardiovascular arousal increased bias in shooting people of color (POCs) first in a shooter task. We expected that participants who played the horror videogame with scary sound effects would have higher cardiovascular arousal and fear than those who played without sound effects. We also expected that increased cardiovascular arousal would increase the likelihood of shooting a POC first (first shot bias) later in a shooter game. The hypothesis that playing the survival horror videogame with scary sound effects would result in higher cardiovascular arousal was supported. First shot bias was not correlated with cardiovascular arousal. However, first shot bias was significantly and positively correlated with enjoyment of the shooter game. A post hoc, exploratory analysis indicated that participants in the scary sound effects condition were significantly more likely to shoot a POC first in the shooter task than those in the no sound effects condition when enjoyment of the shooter game was used as a covariate but not when the covariate was not included. However, this effect was small.
Mechanical Proof of the Maxwell-Boltzmann Speed Distribution With Numerical Iterations
Authors: Lin Hejie , Lin Tsung-Wu
Published: June 2021

The Maxwell-Boltzmann speed distribution is the probability distribution that describes the speeds of the particles of ideal gases. The Maxwell-Boltzmann speed distribution is valid for both un-mixed particles (one type of particle) and mixed particles (two types of particles). For mixed particles, both types of particles follow the Maxwell-Boltzmann speed distribution. Also, the most probable speed is inversely proportional to the square root of the mass.

This paper proves the Maxwell-Boltzmann speed distribution and the speed ratio of mixed particles using computer-generated data based on Newton’s law of motion. To achieve this, this paper derives the probability density function ψ^ab(u_a;v_a,v_b)  of the speed u_a of the particle with mass M_a after the collision of two particles with mass M_a in speed v_a and mass M_b in speed v_b. The function ψ^ab(u_a;v_a,v_b)  is obtained through a unique procedure that considers (1) the randomness of the relative direction before a collision by an angle α. (2) the randomness of the direction after the collision by another independent angle β.

The function ψ^ab(u_a;v_a,v_b) is used in the equation below for the numerical iterations to get new distributions P_new^a(u_a) from old distributions P_old^a(v_a), and repeat with P_old^a(v_a)=P_new^a(v_a), where n_a is the fraction of particles with mass M_a.

P_new^1(u_1)=n_1 ∫_0^∞ ∫_0^∞ ψ^11(u_1;v_1,v’_1) P_old^1(v_1) P_old^1(v’_1) dv_1 dv’_1

                          +n_2 ∫_0^∞ ∫_0^∞ ψ^12(u_1;v_1,v_2) P_old^1(v_1) P_old^2(v_2) dv_1 dv_2

P_new^2(u_2)=n_1 ∫_0^∞ ∫_0^∞ ψ^21(u_2;v_2,v_1) P_old^2(v_2) P_old^1(v_1) dv_2 dv_1

                          +n_2 ∫_0^∞ ∫_0^∞ ψ^22(u_2;v_2,v’_2) P_old^2(v_2) P_old^2(v’_2) dv_2 dv’_2

The final distributions converge to the Maxwell-Boltzmann speed distributions. Moreover, the square of the root-mean-square speed from the final distribution is inversely proportional to the particle masses as predicted by Avogadro’s law.

Published: June 2021

A malária é uma doença com risco de vida evitável e curável, mas houve mais de 228 milhões de casos de malária e 405.000 mortes por malária em 2018. Enquanto mais de 42 milhões de brasileiros estão sob risco de malária, 99% de todos os casos de malária no Brasil estão localizados dentro ou ao redor da floresta amazônica. Apesar do declínio de casos e mortes, a malária continua sendo um grande problema de saúde pública no Brasil. Em resposta a pedidos de novas pesquisas sobre estratégias de eliminação da malária para atender às condições locais, este artigo propõe modelos de machine learning e deep learning para prever a probabilidade de casos de malária no Estado do Amazonas. Usando um conjunto de dados de aproximadamente 6 milhões de registros, avaliamos os modelos {Random Forest, LSTM e GRU e comparamos desempenho por área geográfica usando a classificação de regionais de saúde do Estado do Amazonas e clusters através do algoritmo k-means. Os resultados sugerem que todos os modelos têm uma precisão satisfatória e forte potencial para prever novos casos de malária na região.
